All ltems other than Part ll - ltem 8. are combined for the reporting companies. ITEM 1. BUSINESS ovERvtEw On October 1,20'18, we completed a reorganization into a holding company structure. We believe that our holding company structure is an agile and efficient platform from which to pursue, finance, and oversee new opportunities, such as in the water sector, while also providing legal separation between regulated natural gas distribution operations and other businesses. ln this reorganization, shareholders of NW Natural (the predecessor publicly held parent company) became shareholders of NW Holdings, on a one-for-one basis, with the same number of shares and same ownership percentage as they held in NW Natural immediately prior to the reorganization. NW Natural became a wholly- owned subsidiary of NW Holdings. Additionally, certain subsidiaries of NW Natural were transferred to NW Holdings. As required under accounting guidance, these subsidiaries are presented as discontinued operations in the consolidated results of NW Natural within this report. NW Holdings is a holding company headquartered in Portland, Oregon and owns NW Natural, NW Natural Waler Company (NWWater), and other businesses and activities. NW Natural is NW Holdings' largest subsidiary. NW Natural distributes natural gas to residential, commercial, and industrial customers in Oregon and southwest Washington. NW Natural and its predecessors have supplied gas service to the public since 1 859, was incorporated in Oregon in 1910, and began doing business as NW Natural in 1997. NW Natural's natural gas distribution activities are reported in the natural gas distribution (NGD) segment, formerly titled and reported as the utility segment. All other business activilies, including certain gas storage activities, water businesses, and other investments and activities are aggregated and reported as "other" at their respective registrant. ln addition, NW Holdings has reported discontinued operations results related to the pending sale of Gill Ranch Storage, LLC (Gill Ranch). NW Natural Gas Storage, LLC (NWN Gas Storage), currently an indirect wholly-owned subsidiary of NW Holdings, entered into a Purchase and Sale Agreement during the second quarter of 2018 that provides for the sale of all membership interests in Gill Ranch. Gill Ranch owns a 75% interest in the natural gas storage facility located near Fresno, California known as the Gill Ranch Gas Storage Facility. Pacific Gas and Electric Company (PG&E) owns the remaining 25% interest in the Gill Ranch Gas Storage Facility. NATURAL GAS DTSTRBUTiON (NGD) SEGMENT Both NW Holdings and NW Natural have one reportable segment, the NGD segment, which is conducted by NW Natural. The NGD business purchases and distributes natural gas through approximately 750,000 meters in Oregon and southwest Washington. Approximately 89% of customers are located in Oregon and 11o/o are located in southwest Washington. NW Natural has been allocated an exclusive service territory by the OPUC and WUTC, which includes the major population centers in western Oregon, including the Portland metropolitan area, most of the Willamette Valley, the Coastal area from Astoria to Coos Bay, and portions of Washington along the Columbia River. Portland seryes as one of the largest ports on the West Coast and is a key distribution center. Major businesses located in NW Natural's service terrilory include retail, manufacturing, and high-technology industries. Customers The NGD business serves residential, commercial, and industrial customers with no individual customer accounting for more than 10% of NW Natural or NW Holdings revenues. On an annual basis, residential and commercial customers typically account for approximately 60% of NGD volumes delivered and approximately 90% of margin. lndustrial customers largely account for the remaining volumes and margin. The following table presents summary meter information for the NGD segment as of December 31, 201 8: Number of Meters o/o of o/o of Volumes Margin (') Residential Commercial lndustrial Other Total 680,1 34 69,259 1,028 N/A 37o/o 22o/o 41o/o N/A 650/0 27o/o 8o/o -o/o 750,42'l lOOo/o Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 9 of210 1O0o/o 8 Table of Contents o)NGD margin is also affected by other items, including miscellaneous services, gains or losses from our gas cost incentive sharing mechanism, and other service fees. Generally, residential and commercial customers purchase both their natural gas commodity (gas sales) and natural gas delivery services (transportation services) from the NGD business. lndustrial customers also purchase transportation services, but may buy the gas commodity either from NW Natural or directly from a third-party gas marketer or supplier. Gas commodity cost is primarily a pass{hrough cost to customers; therefore, profit margins are not materially affected by an industrial customer's decision to purchase gas from NW Natural or from third parties. lndustrial and large commercial customers may also select between firm and interruptible service levels, with firm services generally providing higher profit margins compared to interruptible services. To help manage gas supplies, industrial tariffs are designed to provide some certainty regarding industrial customers'volumes by requiring an annual service election, special charges for changes between elections, and in some cases, a minimum or maximum volume requirement before changing options. Customer groMh rates for natural gas utilities in the Pacific Northwest historically have been among the highest in the nation due to lower market saturation as natural gas became widely available as a residential heating source after other fuel options. We estimate natural gas was in approximately 63% of single-family residential homes in NW Natural's service territory in 2018. Customer growth in our region comes mainly from the following sources: single-family housing, both new construction and conversions; multifamily housing new construction; and commercial buildings, both new construction and conversions. Single- family new construction has consistently been our strongest performing source of growth. Continued customer growth is closely tied to the comparative price of natural gas to electricity and fuel oil and the economic health of Portland, Oregon and Vancouver, Washington. We believe there is potential for continued growth as natural gas is a preferred energy source due to its affordable, reliable, and clean qualities. Comoetitive Conditions ln its service areas, the NGD business has no direct competition from other natural gas distributors. However, it competes with other forms of energy in each customer class. This competition among energy suppliers is based on price, efficiency, reliability, performance, preference, market conditions, technology, federal, stale, and local energy policy, and environmental impacts. For residential and small to mid-size commercial cuslomers, the NGD business competes primarily with providers of electricity, fuel oil, and propane. ln the industrial and large commercial markets, the NGD business competes with all forms of energy, including competition from wholesale natural gas marketers. ln addition, large industrial customers could bypass NW Natural's natural gas distribution system by installing their own direct pipeline connection to the interstate pipeline system. NW Natural has designed custom transportation service agreements with several large industrial customers to provide transportation service rates that are competitive with the customer's costs of installing their own pipeline. Seasonality of Business The NGD business is seasonal in nature due to higher gas usage by residential and commercial customers during the cold winter heating months. Other categories of customers experience similar seasonality in their usage but to a lesser extent. Regulation and Rates The NGD business is subject to regulation by the OPUC and WUTC. These regulatory agencies authorize rates and allow recovery mechanisms to provide the opportunity to recover prudently incurred capital and operating costs from customers, while also earning a reasonable return on investment for investors. ln addition, the OPUC and WUTC also regulate the system of accounts and issuance of securities by NW Natural. NW Natural files general rate cases and rate tariff requests periodically with the OPUC and WUTC to establish approved rates, an authorized ROE, an overall rate of return on rate base (ROR), an authorized capital structure, and other revenue/cost deferral and recovery mechanisms. NW Natural is also regulated by the FERC. Under NW Natural's Mist interstate storage certificate with FERC, NW Natural is required to file either a petition for rate approval or a cost and revenue study every five years to change or justify maintaining the existing rates for the interstate storage service. For further discussion on our most recent general rate cases, see Part ll, Item 7, "Results of Operations-Regulatory Matters-Regulation and Rales". Gas Supoly NW Natural strives to secure sufficient, reliable supplies of natural gas to meet the needs of customers at the lowest reasonable cost, while maintaining price stability and managing gas purchase costs prudently. This is accomplished through a comprehensive strategy focused on the following items:. Reliability - ensuring gas resource portfolios are sufficient to satisfy customer requirements under extreme cold weather conditions;. Diverce Supply - providing diversity of supply sources;. Diverce Contracts - maintaining a variety of contract durations, types, and counterparties; and. Cost Management and Recovery - employing prudent gas cost management strategies. Reliability The effectiveness of the natural gas distribution system ultimately rests on whether reliable service is provided to NGD customers. To ensure effectiveness, the NGD business has developed a risk-based methodology in which it uses a planning standard to serve the highest firm sales demand day in any year with 99% certainty. The projected maximum design day firm NGD cuslomer sendout is approximately 1 0.0 million therms. Of this total, Exhibit 3 J. Palfreyman, Falls Water Co., Inc. Page 10 of210 I Table of Contents the NGD business is currently capable of meeling about 560/o of requirements with gas from storage located within or adjacent to the service territory, while the remaining supply requirements would come from gas purchases under firm gas purchase contracts and recall agreements. To supplement near-term natural gas supplies, NW Natural can segment transportation capacity, if needed. Pipeline segmentation is a natural gas transportation mechanism under which a shipper can leverage its firm pipeline transportation capacity by separating it into multiple segments with alternate delivery routes. The reliability of service on these alternate routes will vary depending on the constraints of the pipeline system. For those segments with acceptable reliability, segmentation provides a shipper with increased flexibility and potential cost savings compared to traditional pipeline service. Since 2014, the NGD business has relied on segmentation of firm pipeline transportation capacity that flows from Stanfield, Oregon to various points south of Molalla, Oregon. We believe gas supplies would be sufficient to meet exisling NGD firm customer demand in the event of maximum design day weather conditions. The following table shows the sources of supply projected to be used to satisfy the design day sendout for the 2018-2019 winter heating season Thems in millions Therms Percent Diversitv of Supply Sources NW Natural purchases gas supplies primarily from the Alberta and British Columbia provinces of Canada and multiple receipt points in the U.S. Rocky Mountains to protect against regional supply disruptions and to take advantage of price differentials. For 2018, 61 % of gas supply came from Canada, with the balance primarily coming from the U.S. Rocky Mountain region. We believe gas supplies available in the western United States and Canada are adequate to serve NGD customer requirements for the foreseeable future. NW Natural continues to evaluate the long-term supply mix based on projections of gas production and pricing in the U.S. Rocky Mounlain region as well as other regions in North America. Additionally, the extraction of shale gas has increased the availability of gas supplies throughout North America for the foreseeable future. NW Natural supplements firm gas supply purchases with gas withdrawals from gas storage facilities, including underground reservoirs and LNG storage facilities. Storage facilities are generally injected with natural gas during the off-peak months in the spring and summer, and the gas is withdrawn for use during peak demand months in the winter. The following table presents the storage facilities available for NGD business supply: Sources of NGD supply: Firm supply purchases Mist underground storage (NGD only) Company-owned LNG storage Off-system storage contract Pipeline segmentation capacity Recall agreements Peak day citygate deliveries Total 10.0 The OPUC and WUTC have IRP processes in which utilities define different growth scenarios and corresponding resource acquisition strategies in an effort to evaluate supply and demand resource requirements, consider uncertainties in the planning process and the need for flexibility to respond to changes, and establish a plan for providing reliable service at the least cost. NW Natural files a full IRP biennially for Oregon and Washington with the OPUC and the WUTC, respectively, and files updates between filings. The OPUC acknowledges NW Natural's action plan; whereas the WUTC provides notice that the IRP has met the requirements of the Washington Administrative Code. OPUC acknowledgment of the IRP does not constitute ratemaking approval of any specific resource acquisition strategy or expenditure. However, the Commissioners generally indicate that they would give considerable weight in prudence reviews to actions consistent with acknowledged plans. The WUTC has indicated the IRP process is one factor it will consider in a prudence review. For additional information see Part ll, ltem 7, "Results of Operations-Regulatory Matters". Maximum Daily Deliverability (therms in millions) Designed Storage Capacity (Bcf) Gas Storage Facilities Owned Facility Mist, oregon(') Contracted Facility Jackson Prairie, Washingtone) LNG Facilities Owned Facilities Newport, Oregon Portland, Oregon Total 3.1 (1)The Mist gas storage facility has a total maximum daily deliverability of 5.4 million therms and a total designed storage capacity of aboul 16.0 Bcf, of which 3.1 million therms of daily deliverability and 10.6 Bcf of storage capacity are reserved for NGD business customers. The storage facility is located near Chehalis, Washington and is contracted from Northwest Pipeline, a subsidiary of The Williams Companies. The Mist facility serves NGD segment customers and is also used for non-NGD purposes, primarily for contracts with gas storage customers, including utilities and third-party marketers. Under regulatory agreements with the OPUC and WUTC, gas storage at Mist can be developed in advance of NGD customer needs but is subject to recall when needed to serve such customers as their demand increases. When storage capacity is recalled for NGD purposes it becomes part of the NGD segment. ln 2018, the NGD business did not recall additional deliverability or associated storage capacity to serve customer needs.

Diverse Contract rations and Types NW Natural has a diverse portfolio of shorl-, medium-, and long{erm firm gas supply contracts and a variety of contract types including firm and interruptible supplies as well as supplemental supplies from gas storage facilities. The portfolio of firm gas supply contracts typically includes the following gas purchase contracts: year-round and winter-only baseload supplies; seasonal supply with an option to call on additional daily supplies during the winter heating season; and daily or monthly spot purchases. During 2018, a total of 743 million therms were purchased under contracts with durations outlined in the chart below: These activities, net of the amount shared, are included in other for segment reporting purposes. Gas Cost Recovery Mechanisms for gas cost recovery are designed to be fair and reasonable, with an appropriate balance between the interests of customers and NW Natural. ln general, natural gas distribution rates are designed to recover the costs of, but not to earn a return on, the gas commodity sold. Risks associated with gas cost recovery are minimized by resetting customer rates annually through the PGA and aligning customer and shareholder interests through the use of sharing, weather normalization, and conservation mechanisms in Oregon. See Part ll, Item 7, "Results of Operations-Regulatory Maffers"and "Results of Operations-Business Segments-Natural Gas Distribution Operations-Cosf of Gas. " Transportation of Gas Supplies NW Natural's gas distribution system is reliant on a single, bi-directional interstate transmission pipeline to bring gas supplies into the natural gas distribution system. Although dependent on a single pipeline, the pipeline's gas flows into the Portland metropolitan market from two directions: (1) the north, which brings supplies from the British Columbia and Alberta supply basins; and (2) the east, which brings supplies from Alberta as well as the U.S. Rocky Mountain supply basins. NW Natural incurs monthly demand charges related to firm pipeline transportation contracts. These contracts are multi-year contracts with expirations ranging from 2019 to 2060. The largest pipeline agreements are with Northwest Pipeline. NW Natural actively works with Northwest Pipeline and others to renew contracts in advance of expiration to ensure gas lransportation capacity is sufficient to meet customer needs. Rates for interstate pipeline transportation services are established by FERC within the U.S. and by Canadian authorities for services on Canadian pipelines. As mentioned above, the service territory is dependent on a single pipeline for its natural gas supply. ln October 2018, a critical natural gas pipeline in western Canada experienced a rupture and gas supply to the Pacific Northwest was disrupted. NW Natural was able to serve firm NGD business customers during the incident with natural gas from the Mist storage facility and realignment of other supplies. Pipeline disruptions, replacement projects, and long{erm projected natural gas demand in our region underscore the need for pipeline transportation diversity. ln addition, there are potential industrial projects in the region, which could increase the demand for natural gas and the need for additional pipeline capacity and diversity. Currently, there are various interstate pipeline projects proposed, including the Trail West pipeline in which NW Holdings has an interest, that could meet the forecasted demand groMh for NW Natural and the region. However, the location of any future pipeline project will likely depend on the location of committed industrial projects. NW Holdings and NW Natural will continue to evaluate and closely monitor the currently prospected projects to determine the best option for our customers. NW Holdings Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 12 of 210 Percent of Purchases Long{erm (one year or longer) Short{erm (more than one month, less than one year) Spot (one month or less) Total 28o/o 27 45 lOOo/o Gas supply contracts are renewed or replaced as they expire. During 2018, no individual supplier provided over 10% of the NGD business gas supply requirements. Gas Cost Manaqement The cost of gas sold to NGD customers primarily consists of the following items, which are included in annual PGA rates: gas purchases from suppliers; charges from pipeline companies to transport gas to our distribution system; gas storage costs; gas reserves contracts; and gas commodity derivative contracts. The NGD business employs a number of strategies to mitigate the cost of gas sold to customers. The primary strategies for managing gas commodity price risk include:. negotiating fixed prices directly with gas suppliers;. negotiating financial derivative contracts that: (1) effectively convert floating index prices in physical gas supply contracts to fixed prices (referred to as commodity price swaps); or (2) effectively set a ceiling or floor price, or both, on floating index priced physical supply contracts (referred to as commodity price options such as calls, puts, and collars);. buying physical gas supplies at a set price and injecting the gas into storage for price stability and to minimize pipeline capacity demand costs; and. investing in gas reserves for longer term price stability. See Note 12 for additional information about our gas reserves. NW Natural also contracts with an independent energy marketing company to capture opportunities regarding storage and pipeline capacity when those assets are not serving the needs of NGD business customers. Asset management activities provide opportunities for cost of gas savings for customers and incremental revenues for NW Natural through regulatory incentlve-sharing mechanisms. 11 Table of Contents has an equily investment in Trail West Holdings, LLC (TWH), which is developing plans to build the Trail West pipeline. This pipeline would connect TransCanada Pipelines Limited's (TransCanada) Gas Transmission Northwest (GTN) interstate transmission line to NW Natural's natural gas distribution system. lf constructed, this pipeline would provide another transportation path for gas purchases from Alberta and the U.S. Rocky Mountains in addition to the one that currently moves gas through the Northwest Pipeline system. Gas Distribution The primary goals of gas distribution operations are safety and reliability of the system, which entails building and maintaining a safe pipeline distribution system. Safety and the protection of employees, customers, and the public at large are, and will remain, top priorities. NW Natural constructs, operates, and maintains the pipeline distribution system and storage operations with the goal of ensuring natural gas is delivered and stored safely, reliably, and efficiently. NW Natural has one of the most modern distribution systems in the country with no identified cast iron pipe or bare steel main. The final known bare steel was removed from the system in 2015 and cast iron pipe removal was completed in 2000. Since the 1980s, NW Natural has taken a proactive approach to replacement programs and partnered with the OPUC and WUTC on progressive regulation to further safety and reliability efforts for the distribution system. ln the past, NW Natural had a cost recovery program in Oregon that encompassed programs for bare steel replacement, transmission pipeline integrity management, and distribution pipeline integrity management as appropriate. For discussion on current regulatory programs, see Part ll, ltem T, "Results of Operations-Regulatory Matters". Natural gas distribution businesses will continue to be subject to greater federal and state regulation in the future due lo pipeline incidents involving other companies. Additional operating and safety regulations from the U.S. Department of Transportation's Pipeline and Hazardous Materials Safety Administration (PHMSA) are currently under development. ln 2016, PHMSA issued proposed regulations lo update safety requirements for natural gas transmission pipelines. Final regulations are anticipated to be issued in 2019. Current proposed regulations indicate a 1S-year timeline for implementation of compliance requirements. NW Natural will continue to work diligently with industry associations as well as federal and state regulators to ensure the safety of the system and compliance with new laws and regulations. The costs associated with compliance with federal, state, and local rules are expected to be recovered in rates. North Mist Gas Storaqe Expansion Proiect ln Oregon, there is a need to integrate intermittent resources, such as wind and solar, into the power system with policymakers committing to the elimination of coal-fired electric generation and moving toward a 50% renewable electricity standard by 2040. Flexible natural gas-fired electric generation facilities and associated gas storage are necessary to support the integration of renewable resources. ln 2016, NW Natural began expanding its gas storage facility near Mist, Oregon to provide innovative long-term, no-notice underground gas storage service to support gas-fired electric generating facilities that are intended to facilitate the integration of more wind power into the region's electric generation mix. Natural gas storage enables generation to adjust quickly when renewable energy, such as wind and solar, rises and falls. This expansion project will be dedicated solely to Portland General Electric (Portland General), a local electric company, to support their gas- fired electric power generalion facilities under an inilial 30-year contract with options to extend, totaling up to an additional 50 years upon mutual agreement of the parties. The expansion project includes a new reservoir providing up to 2.5 Bcf of available storage, an additional compressor station with design capacity of 1 20,000 dekatherms of gas per day, no-notice service thal can be drawn on rapidly, and a 13-mile pipeline to connect to Portland General's gas plants at Port Westward. The expansion project is considered part of the NGD segment and has an estimated cost of approximately $149 million, with a targeted in-service date during the spring of 2019. See additional discussion in Part ll, ltem 7 "Financial Condition-Cash Flows-/nyestrn g Activitie s" . When the expansion is placed into service, the investment will be included in rate base under an established tariff schedule already approved by the OPUC, with revenues recognized consistent with the schedule. Billing rates will be updated annually to the current depreciable asset level and forecasted operating expenses. While there are additional expansion opportunities in the Mist storage field, further development is not contemplated at this time and any expansion would be based on market demand, project execution, cost effectiveness, available financing, receipt of future permits, and other rights. OTHER Certain businesses and activities of NW Holdings and NW Natural are aggregated and reported as other for segment reporting purposes. These include the following businesses and activities aggregated and reported as other under NW Holdings:. water businesses and water acquisition activities;. an equity method investment in TWH, a joint venture to build and operate a gas transmission pipeline in Oregon. TWH is owned 50% by NWN Energy, a wholly-owned subsidiary of NW Holdings, and 50% by TransCanada American lnvestments Ltd., an indirect wholly- owned subsidiary of TransCanada Corporation;. a minority interest in the Kelso-Beaver Pipeline held by our wholly- owned subsidiary NNG Financial Corporation (NNG Financial); and. holding company and corporate activities as well as adjustments made in consolidation. Additionally, the following businesses and activities are aggregated and reported as other under NW Natural, a wholly owned subsidiary of NW Holdings: Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 13 of210 12 Table of Contents 5.4 Bcf of the Mist gas storage facility contracted to utilities and third- party marketers; natural gas asset management activities; and appliance retail center operations. WATER. During 2018, NW Water completed the purchase of four privately-owned regulated water utilities serving approximately 22,000 people through 7,400 connections in the Pacific Northwest. Several additional acquisition agreements for privately-owned water utilities have been signed, the largest of which is a water and wastewater business in Sunriver, Oregon serving 9,400 connections. These pending transactions are subject to public utility commission approvals and are expected to close during 2019. MIST GAS STORAGE. The Mist gas storage facility began operations in 1989. lt is a 16 Bcf facility with 10.6 Bcf used to provide gas storage for the NGD business. The remaining 5.4 Bcf of the facility is contracted with other utilities and third-party marketers with these results reported in other. The overall facility consists of seven depleted natural gas reservoirs, 22 injection and withdrawal wells, a compressor station, dehydration and control equipment, gathering lines, and other related facilities. The capacity at Mist serving other utilities and third-party marketers provides multi-cycle gas storage services to customers in the interstate and intrastate markets. The interstate storage services are offered under a Iimited jurisdiction blanket certificate issued by FERC. Under NW Natural's interstate storage certificate with FERC, NW Natural is required to file either a pelition for rate approval or a cost and revenue study every five years to change or justify maintaining the existing rates for the interstate storage service. lntrastate firm storage services in Oregon are offered under an OPUC-approved rate schedule as an optional service to certain eligible customers. Gas storage revenues from the 5.4 Bcf are derived primarily from firm service customers who provide energy-related services, including natural gas distribution, electric generation, and energy marketing. The Mist facility benefits from limited competition as there are few storage facilities in the Pacific Northwest region. Therefore, NW Natural is able to acquire high value, multi-year contracts. ASSET MANAGEMENT ACTIVITES. NW NaturAI CONITACtS With AN independent energy marketing company to provide asset management services, primarily through the use of natural gas commodity exchange agreements and natural gas pipeline capacity release transactions. The results of these activities are included in other, except for the asset management revenues allocated to NGD business customers pursuant to regulatory agreements, which are reBorted in the NGD segment. ENVIRONMENTAL MATTERS Properties and Facilities NW Natural owns, or previously owned, properties and facilities that are currently being investigated that may require environmental remediation and are subject to federal, state, and local laws and regulations related to environmental matters. These laws and regulations may require expenditures over a long time frame to address certain environmental impacts. Estimates of liabilities for environmental costs are difficult to determine with precision because of the various factors that can affect their ultimate disposition. These factors include, but are not limited to, the following:. the complexity of the site;. changes in environmental laws and regulations at the federal, state, and local levels;. the number of regulatory agencies or other parties involved;. new technology that renders previous technology obsolete, or experience with existing technology that proves ineffective;. the ultimate selection of a particular technology;. the level of remediation required;. variations between the estlmated and actual period of time that must be dedicated to respond to an environmentally-contaminated site; and. the application of environmental laws that impose joint and several liabilities on all potentially responsible parties. NW Natural has received recovery of a portion of such environmental costs through insurance proceeds, seeks the remainder of such costs through customer rates, and believes recovery of these costs is probable. ln Oregon, NW Natural has a mechanism to recover expenses, subject to an earnings test and allocation rules. See Part ll, ltem 7, "Results of Operations-Rate Matters-Rate Mechanisms- Environmental Cosfs", Note 2, and Note 17. Greenhouse Gas Matters We recognize our businesses are likely to be affected by requirements to address greenhouse gas emissions. Future federal, state or local requirements may seek to limit emissions of greenhouse gases, including both carbon dioxide (CO2) and methane. These potential laws and regulations may require certain activities to reduce emissions and/or increase the price paid for energy based on its carbon content. Current federal rules require the reporting of greenhouse gas emissions. ln September 2009, the Environmental Protection Agency (EPA) issued a final rule requiring the annual reporting ofgreenhouse gas emissions from certain industries, specified large greenhouse gas emission sources, and facilities that emit 25,000 metric tons or more of CO2 equivalents per year. NW Natural began reporting emission information in 2011. Under this reporting rule, local natural gas distribution companies like NW Natural are required to report system throughput to the EPA on an annual basis. The EPA also has required additional greenhouse gas reporting regulations to which NW Natural is subject, requiring the annual reporting of fugitive emissions from operations. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 14 of210 13 Table of Contents The Oregon and Washington legislatures and governors continue to consider various greenhouse gas reduction proposals and initiatives. For example, the Oregon legislature will be considering a cap and trade bill during the 2019 legislative session that could create a declining cap on greenhouse gas emissions emitted by a wide variety of emission sources, including electric and natural gas utilities, and would require those entities with a compliance obligation to hold permits, or allowances, to emit greenhouse gas emissions on a per ton basis. While there is uncertainty regarding the extent of the legislation, potential compliance costs, and cost sharing impacts of these and other similar proposals, NW Natural currently expects to be able to recover compliance costs associated with this type of legislation in rates. The state of Washington's Department of Ecology (DOE) enacted the Clean Air Rule (CAR) in 2016, which capped the maximum greenhouse gas emissions allowed from stationary sources, such as natural gas utilities. For gas distribution utilities, the production of emissions from usage by their customers was considered to be production of emissions attributable to the utility. ln December 2017, a Washington State Court ruled that the DOE lacked legislative authority to regulate non-emitting sources, such as local distribution companies. The DOE has appealed the ruling and oral arguments for the appeal are expected to take place during 2019. The outcome of these or any additional federal, state or local climate change policy developments cannot be determined at this time, but these initiatives could produce a number of results including new regulations, legal actions, additional charges to fund energy efficiency activities, or other regulatory actions. The adoption and implementation of any regulations limiting emissions of greenhouse gases could require NW Natural to incur compliance costs associated with our customers' use, resulting in an increase in the prices charged to those customers and in a potential decline in the demand for natural gas over time. With environmental stewardship as one of our core values, we continue to take proactive steps to address greenhouse gas emissions in our region and the communities we serve. We believe NW Natural and its modern pipeline system has an important role to play in helping the Pacific Northwest move to a low-carbon, renewable-energy future. We intend to vigorously pursue our role in a low-carbon future, and believe we are positioned to do so. Currently, NW Natural delivers more energy in Oregon than any other utility, and use of natural gas by our Sales and Transportation customers' accounts for approximately 8% of Oregon's greenhouse gas emissions according to the State of Oregon Department of Environmental Quality ln-Boundary GHG lnventory Preliminary 2015 Figures. Sales of natural gas to residential and commercial customers - customers NW Natural procures gas for - accounls for approximately 5% of the state's emissions. Using this as a starting baseline, in2017, NWNatural initiated a multi-pronged, multi- year core utility strategy to deliver greater emission reductions. Key components of this strategy include energy efliciency and the continued adoption of the company's voluntary Smart Energy carbon offset program. NW Natural is also actively pursuing the potential to procure renewable natural gas for our customers, and is engaging in longer- term efforts to explore the development of renewable hydrogen through power to gas. EMPLOYEES At December 31 , 2018, our workforce consisted of the following: NW Natural: Unionized Employees(') Non-Unionized Employees Total NW Natural 1,167 Other Entities: Water Company Employees Other Total Other Entities 31 Total Employees 1 ,198 (1) Members of the Office and Professional Employees lnternational Union (OPEIU) Local No. 11, AFL-CIO. NW Natural's labor agreement with members of OPEIU covers wages, benefits, and working conditions. On May 22, 2014, NW Natural's unionized employees ratified a labor agreement (Joint Accord) that extends to November 30, 2019, and thereafter from year to year unless either party serves notice of its intent to negotiate modifications to the collective bargaining agreement. Certain subsidiaries may receive services from employees of other subsidiaries. When such services involve regulated entities, those entities receiving services reimburse the entity providing services pursuant to shared services agreements.

RISK FACTORS NW Holdings' and NW Natural's business and financial results are subject to a number of risks and uncertainties, many of which are not within our control, which could adversely affect our business, financial condition, and results of operations. Additional risks and uncertainties that are not currently known to us or that are not currently believed by us to be material may also harm our businesses, financial condition, and results of operations. When considering any investment in NW Holdings' or NW Natural's securities, investors should carefully consider the following information, as well as information contained in lhe caption "Forward-Looking Statements", ltem 7A, and our other documents filed with the SEC. This list is not exhaustive and the order of presentation does not reflect management's determination of priority or likelihood. Additionally, our listing of risk factors that primarily affects one of our businesses does not mean that such risk factor is inapplicable to our other businesses. Risks Related to our Business Generally REGULAToRY RISK. Regulafion of NW Holdings'and NW Natural's regulated businesses, including changes in the regulatory environment, failure of regulatory authorities to approve rates which provide for timely recovery of costs and an adequate return on invested capital, or an unfavorable outcome in regulatory proceedings may adversely impact NW Holdings' and NW Natural's financial condition and results of operations. The OPUC and WUTC have general regulatory authority over NW Natural's gas and NW Holdings'water utility businesses in Oregon and Washington, respectively, including: the rates charged to customers; authorized rates of return on rate base, including ROE; the amounts and types of securities our regulated utility companies, like NW Natural, may issue; services our regulated utility companies provide and the manner in which they provide them; the nature of investments our utility companies make; and, deferral and recovery ofvarious expenses, including, but not limited to, pipeline replacement, environmental remediation costs, commodity hedging expense, transactions with affiliated interests, certain employee benefit expenses such as pension, weather adjustment mechanisms, and other matters. The OPUC and WUTC also regulate actions investors may take with respect to our utility companies, NW Natural and NW Holdings. Similarly, FERC has regulatory authority over NW Natural's interstate storage services, and the CPUC has regulatory authority over NW Holdings' Gill Ranch storage operations. Additionally, expansion of our businesses, including into water or other sectors, could result in regulation by other regulatory authorities. For example, NW Holdings' has acquired a water utility business in ldaho that is correspondingly subject to regulatory authority of the IPUC. The prices the OPUC, WUTC, IPUC, and possible future regulators allow us to charge for retail service, and the maximum FERC-approved rates FERC authorizes us to charge for interstate storage and related transportation services, are the most significant factors affecting both NW Natural's and NW Holdings' financial position, results of operations and liquidity. The OPUC, WUTC, IPUC and possible future regulators have the authority to disallow recovery of costs they find imprudently incurred or otherwise disallowed. Additionally, the rates allowed may be insufficient for recovery of costs incurred. We expect to continue to make expenditures to expand, improve and operate our gas and water utility distribution and gas storage systems. Regulators can find such expansions or improvements of expenditures were not prudently incurred, and deny recovery. Additionally, while the OPUC, WUTC and IPUC have established an authorized rate of return for our utility businesses through the ratemaking process, the regulatory process does not provide assurance that we will be able to achieve the earnings level authorized. Moreover, in the normal course of business we may place assets in service or incur higher than expected levels of operating expense before rate cases can be filed to recover those costs- this is commonly referred to as regulatory lag. The failure of any regulatory commission to approve requested rate increases on a timely basis to recover increased costs or to allow an adequate return could adversely impact NW Holdings' or NW Natural's financial condition and results of operations. As companies with regulated utility businesses, we frequently have dockets open with our regulators. The regulatory proceedings for these dockets typically involve multiple parties, including governmental agencies, consumer advocacy groups, and other third parties. Each party has differing concerns, but all generally have the common objective of limiting amounts included in rates. We cannot predict the timing or outcome of these deferred proceedings or the effects of those outcomes on NW Holdings' and NW Natural's results of operations and financial condition. ENVIRONMENTAL LIABILITY RISK. Cerfa,n of NW Natural's, and possibly NW Holdings', propefties and facilities may pose environmental risks requiring remediation, the costs of which are difficult to estimate and which could adversely affect NW Holdings'and NW Natural's financial condition, results of operations, and cash flows. NW Natural owns, or previously owned, properties that require environmental remediation or other action. NW Holdings or NW Natural may now, or in the future, own other properties that require environmental remediation or other action. NW Natural and NW Holdings accrue all material loss contingencies relating to these properties. A regulatory asset at NW Natural has been recorded for estimated costs pursuant to a Deferral Order from the OPUC and WUTC. ln addition to maintaining regulatory deferrals, NW Natural settled with most of its historical liability insurers for only a portion of lhe costs it has incurred to date and expects to incur in the future. To lhe extent amounts NW Natural recovered from insurance are inadequate and it is unable to recover these deferred costs in utility customer rates, NW Natural would be required to reduce its regulatory assets which would result in a charge to earnings in the year in which regulatory assets are reduced. ln addition, in Oregon, the OPUC approved the SRRM, which limits recovery of deferred amounts to those amounts which satisfy an annual prudence review and an earnings test that requires NW Natural to contribute additional amounts toward environmental remediation cosls above approximately $10 million in years in which NW Natural earns above its Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 17 ol 210 16 Table of Contents authorized ROE. To the extent NW Natural earns more than its authorized ROE in a year, it would be required to cover environmental expenses greater than the $10 million with those earnings that exceed its authorized ROE. The OPUC ordered a review of the SRRM in 2018 or when we obtain greater certainty of environmental costs, whichever occurs first. We submitted information for review in 2018, and believe we could be subject to further review. These ongoing prudence reviews, the earnings test, or the periodic review could reduce the amounts NW Natural is allowed to recover, and could adversely affect NW Holdings' or NW Natural's financial condition, results of operations and cash flows. Moreover, we may have disputes with regulators and other parties as to the severity of particular environmental matters, what remediation efforts are appropriate, and the portion of the costs NW Natural or NW Holdings should bear. We cannot predict with certainty the amount or timing of future expenditures related to environmental investigations, remediation or other action, the portions of these costs allocable to NW Natural or NW Holdings, or disputes or litigation arising in relation thereto. Environmental liability estimates are based on current remediation technology, industry experience gained at similar sites, an assessment of probable level of responsibility, and the financial condition of other potentially responsible parties. However, it is difficult to estimate such costs due to uncertainties surrounding the course of environmental remediation, the preliminary nature of certain site investigations, and the application of environmental laws that impose joint and several liabilities on all potentially responsible parties. These uncertainties and disputes arising therefrom could lead lo further adversarial administrative proceedings or litigation, with associated costs and uncertain outcomes, all of which could adversely affect NW Holdings' or NW Natural's financial condition, results of operations and cash flows. ENVIRONMENTAL REGULATION COMPLIANCE RISK. NW Holdings and NW Natural are subject to environmental regulations for our ongoing buslnesses, compliance with which could adversely affect ou operations or financial results. NW Holdings and NW Natural are subject to laws, regulations and other legal requirements enacted or adopted by federal, state and local governmental authorities relating to protection of the environment, including those legal requirements that govern discharges of substances into the air and water, the management and disposal of hazardous substances and waste, groundwater quality and availability, plant and wildlife protection, and other aspects of environmental regulation. For example, our natural gas operations are subject to reporting requirements to the EPA and the ODEQ regarding greenhouse gas emissions. These and other current and future additional environmental regulations could result in increased compliance costs or additional operating restrictions, which may or may not be recoverable in customer rates or through insurance. lf these costs are not recoverable, they could have an adverse effect on NW Holdings' or NW Natural's financial condition and results of operations. GLOBAL CLIMATE CHANGE RISK. Fufure legislation, regulation or other initiatives (including ballot initiatives) to address global climate change may expose NW Holdings and NW Natural to regulatory and financial risk. Additionally, ourbusrnesses may be subject to physical risks associated with climate change, all of which could adversely affect NW Holdings' or NW Natural's financial condition, results ol operations and cash flows. There are a number of international, federal and state legislative and regulatory initiatives being proposed and adopted in an attempt to measure, control or limit the effects of global warming and climate change, including greenhouse gas emissions such as carbon dioxide and methane. For example, there are current legislative efforts in Oregon, Washington, and other states in which we operate to cap or otherwise restrict the maximum GHGs an entity may emit without reduction efforts or other undertakings. Such current or future legislation, regulation or other initiatives (including ballot initiatives) could impose on our natural gas businesses operational requirements, additional charges to fund energy efficiency initiatives, or levy a tax based on carbon content. Such initiatives could result in us incurring additional costs to comply with the imposed restrictions, provide a cost advantage to energy sources otherthan natural gas, reduce demand for natural gas, impose costs or restrictions on end users of natural gas, impact the prices we charge our customers, impose increased costs on us associated with the adoption of new infrastructure and technology to respond to such requirements, and may impact cultural perception of our services or products negatively, diminishing the value of ourbrand, all of which could adversely affect NW Holdings' or NW Natural's business practices, financial condition and results of operations. Climate change may cause physical risks, including an increase in sea level, intensified storms, water scarcity and changes in weather conditions, such as changes in precipitation, average temperatures and extreme wind or other climate conditions. A significant portion of the nation's gas infrastructure is located in areas susceptible to storm damage that could be aggravated by wetland and barrier island erosion, which could give rise to gas supply interruptions and price spikes. These and other physical changes could result in disruptions to natural gas production and transportation systems potentially increasing the cost of gas and affecting our natural gas businesses' ability to procure gas to meet customer demand. These changes could also affect our distribution systems resulting in increased maintenance and capital costs, disruption of service, regulatory actions and lower customer satisfaction. Similar disruptions could occur in NW Holdings'water utility businesses. Additionally, to the extent that climate change adversely impacts the economic health or weather conditions of our service territory directly, it could adversely impact customer demand or our customers' ability to pay. Such physical risks could have an adverse effect on NW Holdings' or NW Natural's financial condition, results of operations, and cash flows. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page '18 of 210 't7 Table of Contents STRATEGIC TRANSACTION RISK. NW Holdings'and NW Natural's ability to successfully complete strategic transactions, including merger, acquisition, divestiture, joint venture, business development projects or other strategic transactlons rs subject to significant risks, including the risk that required regulatory or governmental approvals may not be obtained, risks relating to unknown problems or liabilities or problems or liabilities undisclosed to us, and the isk that for these or other reasons, we may be unable to achieve some or all of the benefits that we anticipate from such transactions, which could adversely affect NW Holdings' or NW Natural's financial condition, results of operations, and cash flows. From time to time, NW Holdings and NW Natural have pursued and may continue to pursue strategic transactions including merger, acquisition, divestiture, joint venture, business development projects or other strategic transactions, including the entry by NW Holdings into the water sector through the acquisition of a number of water utilities and a water services company, with NW Holdings' continuing to seek other such opportunities to acquire additional water companies. Any such transactions involve substantial risks, including the following:. purchase or sale transactions that are contracted for may fail to close for a variety of reasons;. acquired businesses or assets may not produce revenues, earnings or cash flow at anticipated levels;. acquired businesses or assets could have, environmental, permitting, or other problems for which contractual protections prove inadequate;. there may be difficulties in integration or operation costs of new businesses;. there may be liabilities that were not disclosed to us, that exceed our estimates, or for which our rights to indemnification from the seller are limited;. we may be unable to obtain the necessary regulatory or governmental approvals to close a transaction, such approvals may be granted subject to terms that are unacceptable to us, or we may be unable to achieve anticipated regulatory treatment of any such transaction, or such benefits may be delayed or not occur at all; or. we may agree to sell assets for a price that is less than the book value ofthose assets. One of more of these conditions could affect NW Holdings' and NW Natural's financial condition, results of operations, and cash flows. BUSINESS oEVELOPMENT RISR. NW Holdings'and NW Nafural's busrness development projects may encounter unanticipated obstacles, cosfs, changes or delays that could result in a project becoming impaired, which could negatively impact NW Holdings' or NW Natural's financial condition, results of operations and cash flows. Business development projects involve many risks. We are currently engaged in several business development projects, including, but not limited to, NW Holdings' early planning and development stages for a regional pipeline in Oregon, and NW Natural's expansion of its gas storage facility at Mist. We may also engage in other business development projects such as investments in additional long{erm gas reserves, CNG refueling stations, RNG projects, or projects in the water sector. These projects may not be successful. Additionally, we may not be able to obtain required governmental permits and approvals to complete our projects in a cost-efficient or timely manner, potentially resulting in delays or abandonment of the projects. We could also experience issues such as: startup and construction delays; construction cost overruns; disputes with contractors; the inability to negotiate acceptable agreements such as rights-of-way, easements, construction, gas supply or other material contracts; changes in customer demand or commitment; public opposition to projects; changes in market prices; and operating cost increases. Additionally, we may be unable to finance our business development projects at acceptable interest rates or within a scheduled time frame necessary for completing the project. One or more of these events could result in the project becoming impaired, and such impairment could have an adverse effect on NW Holdings' or NW Natural's financial condition and results of operations. JOINT PARTNER RISK. /nyesf,ng,n bus,ness development projects through padnerships, joint ventures or other busrness anangements affects our ability to manage ceftain isks and could adversely impact NW Holdings' or NW Natural's financial condition, results of operations and cash flows. We use joint ventures and other business arrangements to manage and diversify the risks of certain development projects, including NW Holdings' Trail West pipeline and Gill Ranch Facility and NW Natural's gas reserves agreements. NW Holdings or NW Natural may acquire or develop part-ownership interests in other projects in the future, including but not limited to, in the water sector. Under these arrangements, we may not be able to fully direct the management and policies of the business relationships, and other participants in those relationships may take action contrary to our interests, including making operational decisions that could negatively affect our costs and liabllities. ln addition, other participants may withdraw from the project, divest important assets, become financially distressed or bankrupt, or have economic or other business interests or goals that are inconsistent with ours. For example, in January 2019, Pacific Gas & Electric Company, which owns the remaining 25 percent of the Gill Ranch Facility (75 percent of which is owned by NW Holdings), filed for bankruptcy protection. While NW Holdings will monitor that bankruptcy proceeding, and take appropriate actions in an attempt to protect its interests, it does not control, and cannot predict, the outcome of such proceedings and the impact, if any, of the proceeding on the operations of Gill Ranch or the planned sale by NW Holdings' of its interest in Gill Ranch. NW Natural's gas reserves arrangements, which operate as a hedge backed by physical gas supplies, involve a number of risks, including: gas production that is significantly less than the expected volumes, or no gas volumes; operating costs that are higherthan expected; changes in the consolidated tax position or tax laws that could affect NW Natural's ability to take, or the timing of, certain tax benefits that impact the financial outcome of this transaction; inherent risks of gas production, including disruplion to Exhibit 3 J. Palfreyman, Falls WaterCo., lnc. Page 19 ot21O 18 Table of Contents operations or a complete shut-in of the field; and one or more participants in one of these gas reserves arrangements acting contrary to NW Natural's interests. ln addition, while lhe cost of the original gas reserves venture is currently included in customer rates and additional wells under that arrangement are recovered at specific costs, the occurrence of one or more of these risks could affect NW Natural's ability to recover this hedge in rates. Further, new gas reserves arrangements have not been approved for inclusion in rates, and regulators may ultimately determine to not include all or a portion of future transactions in rates. The realization of any of the above mentioned situations could adversely impact NW Holdings' or NW Natural's financial condition, results of operations and cash flows. OPERATING RISK. Iransporf,ng and storing natural gas involves numerous risks that may result in accidents and other operating risks and costs, some or all of which may not be fully covered by insurance, and which could adversely affect NW Holdings' or NW Natural's financial condition, results of operations and cash flows. NW Holdings and NW Natural are subject to all of the risks and hazards inherent in the businesses of gas distribution and storage, and water distribution, including :. earthquakes, floods, storms, landslides and other severe weather incidents and natural hazards;. leaks, losses or contamination of natural gas by other chemicals or compounds or by or of local water as a result of the malfunction of equipment or facilities;. damages from third parties, including construction, farm and utility equipment or other surface users;. operator errors;. negative performance by our storage reservoirs, facilities, or wells that could cause us to fail to meet expected or forecasted operational levels or contractual commitments to our customers;. problems maintaining, or the malfunction of, pipelines, wellbores and related equipment and facilities that form a part of the infrastructure that is crltical to the operation of our gas distribution and storage facilities;. collapse of underground storage caverns;. operating costs that are substantially higher than expected;. migration of natural gas through faults in the rock or to some area of the reservoir where existing wells cannot drain the gas effectively, resulting in loss of the gas;. blowouts (uncontrolled escapes of gas from a pipeline or well) or other accidents, fires and explosions; and. risks and hazards inherent in the drilling operalions associaled with the development of the gas storage facilities, and wells. These risks could result in personal injury or loss of human life, damage to and destruction of property and equipment, pollution or other environmental damage, breaches of our contractual commitments, and may result in curtailment or suspension of operations, which in turn could lead to significant costs and lost revenues. Further, because our pipeline, storage and distribution facilities are in or near populated areas, including residential areas, commercial business centers, and industrial sites, any loss of human life or adverse financial outcomes resulting from such events could be significant. Additionally, we may not be able to maintain the level or types of insurance we desire, and the insurance coverage we do obtain may contain large deductibles or fail to cover certain hazards or cover all potential losses. The occurrence of any operating risks not covered by insurance could adversely affect NW Holdings' or NW Natural's financial condition, results of operations and cash flows. BUSINESS COI{TINUITY RISK. NI4lHoldings and NW Natural may be adversely impacted by local or national disasters, pandemic illness, tenorist activities, cyber-attacks or data breaches, and other extreme events to which we may not be able to promptly respond, which could adversely affect NW Holdings' or NW Natural's operations or financial condition. Local or national disasters, pandemic illness, terrorist activities, cyber- attacks and data breaches, and other extreme events are a threat to our assets and operations. Companies in critical infrastructure industries may face a heightened risk due to exposure to acts of terrorism, including physical and security breaches of our information technology infrastructure in the form of cyber-attacks. These attacks could target or impact our technology or mechanical systems that operate our distribution, transmission or storage facilities and result in a disruption in our operations, damage to our system and inability to meet customer requirements. ln addition, the threat of terrorist activities could lead to increased economic instability and volatility in the price of natural gas or other necessary commodities that could affecl our operations. Threatened or actual national disasters or terrorist activities may also disrupt capital or bank markets and our ability to raise capital or obtain debt financing, or impact our suppliers or our customers directly. Local disaster or pandemic illness could result in part of our workforce being unable to operate or maintain our infrastructure or perform other tasks necessary to conduct our business. A slow or inadequate response to events may have an adverse impact on our operations and earnings. We may not be able to maintain sufficient insurance to cover all risks associated with local and national disasters, pandemic illness, terrorist activities and other events. Additionally, large scale natural disasters or terrorist attacks could destabilize the insurance industry making insurance we do have unavailable, which could increase the risk that an event could adversely affect NW Holdings' or NW Natural's operations or financial results. HOLDING COMPANY DIVIDEND RISK. As a holding company, NW Holdings depends on its operating subsidiaries, including NW Natural, to meet financial obligations and the ability of NW Holdings to pay dividends on its common stock is dependent on the receipt of dividends and other payments from its subsidiaries, including NW Natural. As a holding company, NW Holdings' only significant assets are the stock and membership interests of its operating subsidiaries, which at this time is primarily NW Natural. NW Holdings'direct and indirect subsidiaries are separate and distinct legal entities, managed by their own boards of directors, and have no obligation to pay any amounts to their respective shareholders, whether through dividends, loans or other payments. The ability of these companies to pay dividends or make other distributions on their common stock is subject to, among other things: their results of operations, net income, cash flows and financial condition, as well as the success of their business strategies and Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 20 of 210 19 Table of Contents general economic and competitive conditions; the prior rights of holders of existing and future debt securities and any future preferred stock issued by those companies; and any applicable legal restrictions. ln addition, the ability of NW Holdings' subsidiaries to pay upstream dividends and make other distributions is subject to applicable state law and regulatory restrictions. Under the OPUC and WUTC regulatory approvals for the holding company formation, if NW Natural ceases to comply with credit and capital structure requirements approved by the OPUC and WUTC, il will not, with limlted exceptions, be permitted to pay dividends to NW Holdings. Under the OPUC and WUTC orders authorizing the holding company reorganization, NW Natural may not pay dividends or make distributions to NW Holdings if NW Natural's credit ratings and common equity levels fall below specified ratings and levels. lf NW Natural's long{erm secured credit ratings are below A- for S&P and A3 for Moody's, dividends may be issued so long as NW Natural's common equity is 45% or above. lf NW Natural's long-term secured credit ratings are below BBB for S&P and Baa2 for Moody's, dividends may be issued so long as NW Natural's common equity is 46% or above. Dividends may not be issued if NW Natural's long{erm secured credit ratings fall to BB+ or below for S&P or Ba1 or below for Moody's, or if NW Natural's common equity is below 44o/o.ln each case, with the common equity level to be determined on a preceding or projected '13- month basis. EMPLOYEE BENEFIT RISK. Ihe cost of providing pension and postretirement healthcare benefits is subject to changes in pension assefs and /labilities, changing employee demographics and changing actuarial assumptions, which may have an adverse effect on NW Holdings' or NW Natural's financial condition, results of operations and cash flows. Until NW Natural closed the pension plans to new hires, which for non- union employees was in 2006 and for union employees was in 2009, it provided pension plans and postretirement healthcare benefits to eligible full-time utility employees and retirees. About half of NW Natural's current utility employees were hired prior to these dates, and therefore remain eligible for these plans. Other businesses we acquire may also have pension plans. The costs of NW Natural, or the other applicable businesses we may acquire, for providing such benefits is subject to change in the market value of the pension assets, changes in employee demographics including longer life expectancies, increases in healthcare costs, current and future legislative changes, and various actuarial calculations and assumptions. The actuarial assumptions used to calculate our future pension and postretirement healthcare expenses may differ materially from actual results due to significant market fluctuations and changing withdrawal rates, wage rates, interest rates and other factors. These differences may result in an adverse impact on the amount ofpension contributions, pension expense or other postretirement benefit costs recorded in future periods. Sustained declines in equity markets and reductions in bond rates may have a material adverse effect on the value of the pension fund assets and liabilities. ln these circumstances, NW Natural may be required to recognize increased contributions and pension expense earlier than it had planned to the exlent that the value of pension assets is less than the total anticipated liability under the plans, which could have a negative impact on NW Holdings' and NW Natural's financial condition, results of operations and cash flows. WORKFORCE RlsK. NW Holdings'and NW Nafural5 busrnesses are heavily dependent on being able to attract and retain qualified employees and maintain a competitive cost structure with ma*et-based salaries and employee benefits, and workforce disruptions could adversely affect NW Holdings' or NW Natural's operations and results. NW Holdings' and NW Natural's ability to implement our business strategy and serve our customers is dependent upon our continuing ability to attract and retain talented professionals and a technically skilled workforce, and being able to transfer the knowledge and expertise of our workforce to new employees as our largely older workforce retires. We expect that a significant portion of our workforce will retire within the current decade, which will require that we attract, train and retain skilled workers to prevent loss of institutional knowledge or skills gaps. Wilhout an appropriately skilled workforce, our ability to provide qualig service and meet our regulatory requirements will be challenged and this could negatively impact NW Holding's and NW Natural's earnings. Additionally, a majority of NW Natural workers are represented by the OPEIU Local No.11 AFL-ClO, and are covered by a collective bargaining agreement that extends to November 30, 2019. Disputes with the union representing NW Natural employees over terms and conditions of their agreement, or failure to timely and effectively renegotiate the agreement, could result in instability in our labor relationship and work stoppages that could impact the timely delivery of gas and other services from our utility and storage facilities, which could strain relationships with customers and state regulators and cause a loss of revenues. The collective bargaining agreements may also limit our flexibility in dealing with NW Natural's workforce, and the ability to change work rules and practices and implement olher efficiency-related improvements to successfully compete in today's challenging marketplace, which may negatively affect NW Holdings' and NW Natural's financial condition and results of operations. LEG|SLATIVE, COMPLIANCE AND TAXING AUTHORITY RISK. NW Holdings and NW Natural are subject to governmental regulation, and compliance with local, state and federal requirements, including taxing requirements, and unforeseen changes in or interpretations of such requirements could affect NW Holdings' or NW Natural's financial condition and results of operations. NW Holdings and NW Natural are subject to regulation by federal, state and local governmental authorities. We are required to comply with a variety of laws and regulations and to obtain authorizations, permits, approvals and certificates from governmental agencies in various aspects of our business. Significant changes in federal, state, or local governmental leadership can accelerate or amplify changes in existing laws or regulations, or the manner in which they are interpreted or enforced. For example, the current U.S. presidential administration has made numerous leadership changes at federal administrative agencies since the 2016 U.S. presidential election. Moreover, the U.S. Congress and the U.S. presidential administration may Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 21 of 210 20 Table of Contents make substantial changes to fiscal, tax, regulation and otherfederal policies. The current U.S. presidential administration has called for and implemented significant changes to U.S. fiscal policies, U.S. trade, healthcare, immigration, foreign, and government regulatory policy. To the extent the U.S. Congress or U.S. presidential administration implements changes to U.S. policy, those changes may impact, among other things, the U.S. and global economy, international trade and relations, unemployment, immigration, corporate taxes, healthcare, the U.S. regulatory environment, inflation and other areas. ln addition, foreign governments may implement changes to their policies, in response to changes to U.S. policy or otherwise. Although we cannot predict the impact, if any, of these changes to our businesses, they could adversely affect NW Holdings' or NW Natural's financial condition and results of operations. Until we know what policy changes are made and how those changes impact our businesses and the business of our competitors over the long term, we will not know if, overall, we will benefit from them or be negatively affected by them. Though we cannot predict changes in laws, regulations, or enforcement, we expect there to continue to be a number of significant changes. We cannot predict with certainty the impact of any future revisions or changes in interpretations of existing regulations or the adoption of new laws and regulations. Additionally, any failure to comply with existing or new laws and regulations could result in fines, penalties or injunctive measures that could affect operating assets. For example, under the Energy Policy Act of 2005, the FERC has civil authority under the Natural Gas Act to impose penalties for current violations of in excess of $1 million per day for each violation. ln addition, as the regulatory environment for our businesses increases in complexity, the risk of inadvertent noncompliance may also increase. Changes in regulations, the imposition of additional regulations, and the failure to comply with laws and regulations could negatively influence NW Holdings' or NW Natural's operating environment and results of operations. Additionally, changes in federal, state or local tax laws and their related regulations, or differing interpretations or enforcement of applicable law by a federal, state or local taxing authority, could result in substantial cost to us and negatively affect our results of operations. Tax law and its related regulations and case law are inherently complex and dynamic. Disputes over interpretations of tax laws may be settled with the taxing authority in examination, upon appeal or through litigation. Our ludgments may include reserves for potential adverse outcomes regarding tax positions that have been taken that may be subject to challenge by taxing authorities. Changes in laws, regulations or adverse iudgments and the inherent difficulty in quantifoing potential tax effects of business decisions may negatively affect NW Holdings' or NW Natural's financial condition and results of operations. ln this regard, the Tax Cuts and Jobs Act of 201 7 was approved by the U.S. Congress on December 20,2017 and signed into law by the U.S. President on December 22,2017. This legislation makes significant changes to the U.S. lnternal Revenue Code. Such changes include a reduction in the corporate tax rate from 35% to 21o/o and limitations on certain corporate deductions and credits, among other changes. Certain of these changes may negatively affect NW Holdings' and NW Natural's financial condition and results of operations. There is uncertainty as to how our regulators will reflect the impact of the legislation in rates. The resulting ratemaking treatment may negatively affect NW Holdings'or NW Natural's financial condition and results of operations. SAFETY REGULATION RISK. NW Holdings and NW Natural may experience increased federal, state and local regulation of the safety of our systems and operations, which could adversely affect NW Holdings' or NW Natural's operating costs and financial results. The safety and protection ofthe public, our customers and our employees is and will remain our top priority. We are committed to consistently monitoring and maintaining our distribution systems and storage operations to ensure that natural gas is acquired, stored and delivered safely, reliably and efficiently. Given recent high-profile natural gas explosions, leaks and accidents in other parts of the country involving both distribution systems and storage facilities, we anticipate that the natural gas industry may be the subject of even greater federal, state and local regulatory oversight. Forexample, in 2016, the Protecting our lnfrastructure of Pipelines and Enhancing Safety Act (PIPES Act) was signed into law increasing regulations for natural gas storage pipelines and underground storage facilities. Similarly, in 2016, California passed legislation directing the Department of Oil, Gas and Geothermal Resources (DOGGR) to develop regulations affecting gas storage operations. DOGGR has issued regulations which require certain integrity testing and tubing for wells at the Gill Ranch Facility within the next 7 years. We intend to work diligently with industry associations and federal and state regulators to seek to ensure compliance with these and other new laws. We expect there to be increased costs associated with compliance, and those cosls could be significant. lf these costs are not recoverable in our customer rates, they could have a negative impact on NW Holdings' and NW Natural's operating costs and financial results. HEDGING RISK. Nl4l Natura I's risk management policies and hedging activities cannot eliminate the risk of commodity price movements and other financial market risks, and its hedging activities may expose it to additional liabilities for which rate recovery may be disallowed, which could result in an adverse impact on NW Holdings'and NW Natural's operating revenues, cosfs, derivative assets and liabilities and operating cash flows. NW Natural's gas purchasing requirements expose it to risks of commodity price movements, while its use of debt and equity financing exposes it to interest rate, liquidity and other financial market risks. NW Natural attempts to manage these exposures with both financial and physical hedging mechanisms, including its gas reserves transactions which are hedges backed by physical gas supplies. While NW Natural has risk management procedures for hedging in place, they may not always work as planned and cannot entirely eliminate the risks associated with hedging. Additionally, NW Natural's hedging activities may cause it to Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 22 of 210 21 Table of Contents incur additional expenses to obtain the hedge. NW Natural does not hedge its entire interest rate or commodity cost exposure, and the unhedged exposure will vary over time. Gains or losses experienced through hedging activities, including carrying costs, generally flow through NW Natural's PGA mechanism or are recovered in future general rate cases. However, the hedge transactions NW Natural enters into for utility purposes are subject to a prudence review by the OPUC and WUTC, and, if found imprudent, those expenses may be, and have been previously, disallowed, which could have an adverse effect on NW Holdings' or NW Natural's financial condition and results of operations. ln addition, NW Natural's actual business requirements and available resources may vary from forecasts, which are used as the basis for its hedging decisions, and could cause its exposure to be more or less than anticipated. Moreover, if NW Natural's derivative instruments and hedging transactions do not qualify for regulatory deferral and it does not elect hedge accounting treatment under U.S. GAAP, NW Holdings'or NW Natural's results of operalions and financial condition could be adversely affected. NW Natural also has credit-related exposure to derivative counterparties. Counterparties owing NW Natural or its subsidiaries money or physical natural gas commodities could breach their obligations. Should the counterparties to these arrangements fail to perform, NW Natural may be forced to enter into alternative arrangements to meet its normal business requirements. ln that event, NW Holdings' or NW Natural's financial results could be adversely affected. Additionally, under most of NW Natural's hedging arrangements, any downgrade of its senior unsecured long{erm debt credit rating could allow its counterparties to require NW Natural to post cash, a letter of credit or other form of collateral, which would expose NW Natural to additional costs and may trigger significant increases in borrowing from its credit facilities or equity contribution needs from NW Holdings, if the credit rating downgrade is below investment grade. Further, based on current interpretations, NW Natural is nol considered a "swap dealer" or "major swap participant" in 2019, so NW Natural is exempt from certain requirements under the Dodd-Frank Act. lf NW Natural is unable to claim this exemption, it could be subject to higher costs for its derivatives activities, and such higher costs could have a negative impact on NW Holdings' and NW Natural's operating costs and financial results. INABILITY TO ACCESS CAPITAL MARKET R\SR. NW Holdings'or NW Natural's inability to access capital, or significant increases in the cost of capital, could adversely affect NW Holdings' or NW Natural's financial condition and results of operations. NW Holdings'and NW Natural's ability to obtain adequate and cost effective shortterm and long{erm financing depends on maintaining investment grade credit profiles as well as the existence of liquid and stable financial markets. NW Holdings relies on access to equity and bank markets to finance equity contributions to subsidiaries and other business requirements. NW Natural relies on access to capital and bank markets, including commercial paper and bond markets, to finance its operations, construction expenditures and other business requirements, and to refund maturing debt that cannot be funded entirely by internal cash flows. Disruptions in capital markets could adversely affect our ability to access short{erm and long-term financing. Our access to funds under committed credit facilities, which are currently provided by a number of banks, is dependent on the ability of the participating banks to meet their funding commitments. Those banks may not be able to meet their funding commitments if they experience shortages of capital and liquidity. Disruptions in the bank or capital financing markets as a result of economic uncertainty, changing or increased regulation of the financial sector, or failure of major financial institutions could adversely affect NW Holdings' and NW Natural's access to capital and negatively impact our ability to run our businesses and make strategic investments. NW Natural is currently rated by S&P and Moody's and a negative change in its credit ratings, particularly below investment grade, could adversely affect its cost of borrowing and access to sources of liquidity and capital. Such a downgrade could further limit its access to borrowing under available credit lines. Additionally, downgrades in its current credit ratings below investment grade could cause additional delays in NW Natural's ability to access the capital markets while it seeks supplemental state regulatory approval, which could hamper its ability to access credit markets on a timely basis. NW Holdings'credit profile is largely supported by NW Natural's credit ratings and any negative change in NW Natural's credit ratings would likely negatively impact NW Holdings' access to sources of liquidity and capital and cost of borrowing. A credit downgrade to NW Natural, or resulting negative impacl on NW Holdings, could also require additional support in the form of letters of credit, cash or other forms of collateral and othenvise adversely affect NW Holdings'or NW Natural's financial condition and results of operations. REPUTATIONAL RISKS. Cusforners', legislators', and regulators' opinions of NW Holdings and NW Natural are affected by many factors, including system reliability and safety, protection of customer information, rates, media coverage, and public sentiment. To the extent that customers, legislators, or regulators have or develop a negative opinion of our busrnesses, NW Holdings' and NW Natural's linancial positions, results of operations and cash flows could be adversely affected. A number of factors can affect customer satisfaction including: service interruptions or safety concerns due to failures of equipment or facilities or from other causes, and our ability to promptly respond to such failures; our ability to safeguard sensitive customer information; the timing and magnitude of rate increases; and volatility of rates. Customers', legislators', and regulators' opinions of us can also be affected by media coverage, including the proliferation of social media, which may include information, whether factual or not, that damages our brand and reputation. lf customers, legislators, or regulators have or develop a negative opinion of us and our services, this could result in increased regulatory oversight and could affect the returns on common equity we are allowed to earn. Additionally, Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 23 of 210 22 Table of Contents negative opinions about us could make it more difficult for us to achieve favorable legislative or regulatory outcomes. Negative opinions could also result in sales volumes reductions or increased use of other sources ofenergy. Any ofthese consequences could adversely affect NW Holdings' or NW Natural's financial position, resulls of operations and cash flows. RELnNCE ON TECHNOLOGY R|SK. Nt//Holdings' and NW Natural's efforts to integrate, consolidate and streamline each of their operations has resulted in increased reliance on technology, the failure or security breach of which could adversely affect NW Holdings' or NW Natural's financial condition and results of operations. Over the last several years NW Holdings and NW Natural have underlaken a variety of iniliatives to integrate, standardize, centralize and streamline operations. These efforts have resulted in greater reliance on technological tools such as, at NW Natural: an enterprise resource planning system, an automated dispatch system, an automated meter reading system, a customer information system, a web-based ordering and tracking system, and other similar technological tools and initiatives. The failure of any of these or other similarly important technologies, or our inability to have these technologies supported, updated, expanded or integrated inlo other technologies, could adversely impact operations. We take precautions to protect our systems, but there is no guarantee that the procedures we have implemented to protect against unauthorized access to secured data and systems are adequate to safeguard against all security breaches. Our businesses could experience breaches of security pertaining to sensitive customer, employee, and vendor information maintained by us in the normal course of business, which could adversely affect our reputation, diminish customer confidence, disrupt operations, materially increase the costs we incur to protect against these risks, and subject us to possible financial liability or increased regulation or litigation, any of which could adversely affect NW Holdings' or NW Natural's financial condition and results of operations. Furthermore, we rely on information technology systems in the operation of our businesses. There are various risks associated with these systems, including hardware and software failure, communications failure, data distortion or destruction, unaulhorized access to data, misuse of proprietary or confidential data, unauthorized control through electronic means, programming mistakes and other inadvertent errors or deliberate human acts. ln particular, cyber security attacks, data breaches, terrorism or other malicious acts could damage, destroy or disrupt all of our business systems. Any failure of information technology systems could result in a loss of operating revenues, an increase in operating expenses and costs to repair or replace damaged assets. As these potential cyber security attacks become more common and sophisticated, we could be required to incur costs to strengthen our systems or obtain specific insurance coverage against potential losses. REGULATORY ACCOUNTTNG R|SK. /n the future, NW Holdings or NW Natural may no longer meet the criteria for continued application of regulatory accounting practices for all or a portion of our regulated operations. lf we can no longer apply regulatory accounting, we could be required to write off our regulatory assets and precluded from the future deferral of costs not recovered through rates at the time such amounts are incurred, even if we are expected to recover these amounts from customers in the future. GAS PRICE RISK. Higher natural gas commodity prices and volatility in the pice of gas may adversely affect NW Natural's NGD busrnesq whereas lower gas price volatility may adversely affect NW Natural's and NW Holdings' gas storage busrness, in each case negatively affecting NW Holdings' and NW Natural's results of operations and cash flows. The cost of natural gas is affected by a variety of factors, including weather, changes in demand, the level of production and availability of natural gas supplies, transportation constraints, availability and cost of pipeline capacity, federal and state energy and environmental regulation and legislation, natural disasters and other catastrophic events, national and worldwide economic and political conditions, and the price and availability of alternative fuels. At NW Natural, the cost we pay for natural gas is generally passed through to customers through an annual PGA rate adjustment. lf gas prices were to increase significantly, it would raise the cost of energy to NW Natural's customers, potentially causing those customers to conserve or switch to alternate sources of energy. Significant price increases could also cause new home builders and commercial developers to select alternative energy sources. Decreases in the volume of gas NW Natural sells could reduce NW Holdings or NW Natural's earnings, and a decline in customers could slow growth in future earnings. Additionally, because a portion (10o/o or 20o/o) of any difference between the estimated average PGA gas cost in rates and the actual average gas cost incurred is recognized as current income or expense, higher average gas costs than those assumed in setting rates can adversely affect NW Holdings' and NW Natural's operating cash flows, liquidity and results of operations. Additionally, notwithstanding NW Natural's currenl rate structure, higher gas costs could result in increased pressure on the OPUC or the WUTC to seek other means to reduce NW Natural's rates, which also could adversely affect NW Holdings' and NW Natural's results of operations and cash flows. Higher gas prices may also cause NW Naturalto experience an increase in short-term debt and temporarily reduce liquidity because it pays suppliers for gas when it is purchased, which can be in advance of when these costs are recovered through rates. Significant increases in the price of gas can also slow collection efforts as customers experience increased difficulty in paying their higher energy bills, leading to higher than normal delinquent accounts receivable resulting in greater expense associated with collection efforts and increased bad debt expense. Conversely, storage businesses benefit from price volatility, which impacts the level of demand for services and the rates that can be charged for storage services. Largely due to the abundant supply of natural gas made available by hydraulic fracturing techniques, natural gas prices have dropped significantly to levels that are near historic lows. lf prices and volatility remain low or decline further, then the Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 24 of 210 23 Table of Contents demand for storage services, and the prices that we will be able to charge for those services, may decline or be depressed for a prolonged period of time. Prices below the costs to operate a storage facility could result in a decision to shut-in all or a portion of the facility. A sustained decline in these prices or a shut-in of all or a portion of the facility could have an adverse impact on NW Holdings'or NW Natural's financial condition, results of operations and cash flows. IMPAIRmENT OF LONG-LIVED ASSETS OR G@DWILL RISK. lmpairments of the value of long-lived assets or goodwill could have a material effect on NW Holdings' or NW Natural's financial condition, or results of operations. NW Holdings and NW Natural review the carrying value of long-lived assets whenever events or changes in circumstances indicate the carrying amount of the assets might not be recoverable. The determination of recoverability is based on the undiscounted net cash flows expected to result from the operation of such assets. Projected cash flows depend on the future operating costs and projected revenues associated with the asset. ln 2017, NW Natural recognized a $192.5 million impairment of long-lived assets at the Gill Ranch Facility as of December 31 , 2017 . We review our other long-lived assets to determine if an impairment analysis is necessary. We review the carrying value of goodwill annually or whenever evenls or changes in circumstances indicate that such carrying value may not be recoverable. A goodwill impairment analysis begins with a qualitative analysis of events and circumstances. lf the qualitative assessment indicates that the carrying value may be at risk, we will perform a quantitative assessment and recognize a goodwill impairment for any amount in which the fair value of a reporting unit exceeds its fair value. Any impairment charge taken with respect to our long-lived assets or goodwill could be material and could have a material effect on NW Holdings' or NW Natural's financial condition and results of operations. CUSToMER GROWTH RlsK. NW Holdings' and NW Natural's NGD margin, earnings and cash flow may be negatively affected if we are unable to sustain customer growth rates in our NGD segment. NW Natural's NGD margins and earnings growth have largely depended upon the suslained growth of its residential and commercial customer base due, in part, to the new construction housing market, conversions of customers to natural gas from other energy sources and growing commercial use of natural gas. The last recession slowed new construction. While new home construction has resumed and the multi- family composition has been higher than its pre-recession pace, overall construction has not returned to the pre-recession pace, and there are predictions of an impending new recessionary cycle. lnsufficient growth in these markets, for economic, political or other reasons could adversely affect NW Holdings' or NW Natural's utility margin, earnings and cash flows. RISK OF COMPETITION. Our NGD busrness ls subject to increased competition which could negatively affect NW Holdings'or NW Natural's results of operations. ln the residential and commercial markets, NW Natural's NGD business competes primarily with suppliers of electricity, fuel oil, and propane. ln the industrial market, NW Natural competes with suppliers of all forms of energy. Competition among lhese forms of energy is based on price, efficiency, reliability, performance, market conditions, technology, environmental impacts and public perception. Technological improvements in other energy sources such as heat pumps, batteries or other alternative technologies could erode NW Natural's competitive advantage. lf natural gas prices rise relative to other energy sources, or if the cost, environmental impact or public perception of such other energy sources improves relative to natural gas, it may negatively affect NW Natural's ability to attract new customers or retain our existing residential, commercial and industrial customers, which could have a negative impact on our customer growth rate and NW Holdings' and NW Natural's results of operations. Our natural gas storage operations compete primarily with other storage facilities and pipelines. Natural gas storage is an increasingly competitive business, with the ability to expand or build new storage capacity in California, the U.S. Rocky Mountains and elsewhere in the United States and Canada. lncreased competition in the natural gas storage business could reduce the demand for our natural gas storage services, drive prices down for our storage business, and adversely affect our ability lo renew or replace existing contracts at rates sufficient to maintain current revenues and cash flows, which could adversely affect NW Holdings' and NW Natural's financial condition, results of operations and cash flows. RELIANCE ON THIRO PARTIES TO SUPPLY NATURAL GAS RISK. NW NatuTaI relies on third parties to supply the natural gas in its NGD segment, and limitations on NW Natural's ability to obtain supp/res, or failure to receive expected supplies for which it has contracted, could have an adverse impact on NW Holdings'or NW Natural'sfinancial results. NW Natural's ability to secure natural gas for current and future sales depends upon its ability to purchase and receive delivery of supplies of natural gas from third parties. NW Natural, and in some cases, its suppliers of natural gas, does not have control over the availability of natural gas supplies, competition for those supplies, disruptions in lhose supplies, priority allocations on transmission pipelines, or pricing of those supplies. Additionally, third parties on whom NW Natural relies may fail to deliver gas for which it has contracted. For example, on October 9, 2018, a 36-inch pipeline near Prince George, British Columbia owned by Enbridge ruptured, disrupting natural gas flows from Canada into Washington while the ruptured pipeline and an adjacent pipeline were assessed and the ruptured pipeline was repaired. Once repaired, pressurization levels for those pipelines were reduced for assessment and testing. lf NW Natural is unable or limited in its ability to obtain natural gas from its current suppliers or new sources, it may not be able to meet customers'gas requirements and would likely incur costs associated with actions necessary to mitigate service disruptions, both of which could significantly and negatively impact NW Holdings' and NW Natural's results of operations. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 25 ol21O 24 Table of Contents SINGLE TRANSPORTATION PIPELINE RISK. /Vt/VNatural relies on a single pipeline company for the transpoftation of gas to its service tenitory, a disruption of which could adversely impact its ability to meet customers' gas requirements, which could significantly and negatively impact NW Holdings' and NW Natural's results of operations. NW Natural's distribution system is directly connected to a single interstate pipeline, which is owned and operated by Northwest Pipeline. The pipeline's gas flows are bidirectional, transporting gas into the Portland melropolitan market from two directions: (1) the north, which brings supplies from the British Columbia and Alberta supply basins; and (2) the east, which brings supplies from the Alberta and the U.S. Rocky Mountain supply basins. lf there is a rupture or inadequate capacity in the pipeline, NW Natural may not be able to meet its customers' gas requirements and we would likely incur costs associated with actions necessary to mitigate service disruptions, both of which could significantly and negatively impact NW Holdings'and NW Natural's results of operations. THIRD PARTY PIPELINE RISK. NW Holdings'and NW Natural's gas storage buslnesses depend on third-party pipelines that connect our storage facilities to interstate pipelines, the failure or unavailability of which could adversely affect NW Holdings' or NW Natural's financial condition, results of operations and cash flows. Our gas storage facilities are reliant on the continued operation of a third-party pipeline and other facilities that provide delivery options to and from our storage facilities. Because we do not own all of these pipelines, their operations are not within our control. lf the third-party pipeline to which we are connected were lo become unavailable for current or future withdrawals or injections of natural gas due to repairs, damage to the infrastructure, lack of capacity or other reasons, our ability to operate efficiently and satisfy our customers' needs could be compromised, thereby potentially having an adverse impact on NW Holdings' or NW Natural's financial condition, results of operations and cash flows. WEATHER RISK. Warmer than average weather may have a negative impact on our revenues and results of operations. We are exposed to weather risk in our natural gas business, primarily at NW Natural. A majority of NW Natural's gas volume is driven by gas sales to space heating residential and commercial customers during the winter heating season. Current NW Natural rates are based on an assumption of average weather. Warmer than average weather typically results in lower gas sales. Colder weather typically results in higher gas sales. Although the effects of warmer or colder weather on utility margin in Oregon are expected to be mitigated through the operation of NW Natural's weather normalization mechanism, weather variations from normal could adversely affect utility margin because NW Natural may be required to purchase more or less gas at spot rates, which may be higher or lower than the rates assumed in its PGA. Also, a portion of NW Natural's Oregon residential and commercial customers (usually less than 10%) have opted out of the weather normalization mechanism, and 1 1% of its customers are located in Washington where it does not have a weather normalization mechanism. These effects could have an adverse effect on NW Holdings' and NW Natural's financial condition, results of operations and cash flows. CUSTOIIIER CONSERVATION RISK. Cusfome rs' co n se rv ati on effo ft s m ay have a negative impact on NW Holdings'and NW Natural5 revenues. An increasing national focus on energy conservation, including improved building practices and appliance efficiencies may result in increased energy conservation by customers. This can decrease NW Natural's sales of natural gas and adversely affect NW Holdings' or NW Natural's results of operations because revenues are collected mostly through volumetric rates, based on the amount of gas sold. ln Oregon, NW Natural has a conservation tariff which is designed to recover lost utility margin due to declines in residential and small commercial customers' consumption. However, NW Natural does not have a conservation tariff in Washington that provides it this margin protection on sales to customers in that state. Similar conservation risks exist for waler utilities. Customers' conservation efforts may have a negative impact on NW Holding's and NW Natural's financial condition, revenues and results of operations. Risks Related Primarily to NW Holdings'Illate!€eglqI Businesses NEw WATER SECTOR BUSINESS. NW Holdings has entered the water sector through the acquisition of a number of water companies. Water busrnesses are subject to a number of risks in addition to the risks described above. Although the water businesses are not currently expected to materially contribute to the results of operations of NW Holdings, these businesses are subject to risks, in addition to those described above that could adversely affect their results of operations, including: contamination of water supplies, including water provided to customers; interruptions in water supplies and droughls; conservation efforts by customers; regulatory requiremenls; and weather conditions. Significant losses, liabilities or impairments arising from these businesses may adversely affect NW Holdings'financial position or results of operations. ITEM 1B.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS On October 1,2018, we completed a reorganization into a holding company structure. We believe that our holding company structure is an agile and efficient platform from which to pursue, finance, and oversee new opportunities, such as in the water sector, while also providing legal separation between regulated natural gas distribution operations and olher businesses. ln this reorganization, shareholders of NW Natural (the predecessor publicly held parent company) became shareholders of NW Holdings, on a one-for-one basis, with the same number of shares and same ownership percentage as they held in NW Natural immediately prior to the reorganization. NW Natural became a wholly- owned subsidiary of NW Holdings. Additionally, certain subsidiaries of NW Natural were transferred to NW Holdings. As required under accounting guidance, these subsidiaries are presented as discontinued operations in the consolidated results of NW Natural within this report. NW Holdings is a holding company headquartered in Portland, Oregon and owns NW Natural, NWN Water, and other businesses and activities. NW Natural is NW Holdings'largest subsidiary. NW Natural's natural gas distribution activities are reported in the natural gas distribution (NGD) segment, formerly titled and reported as the utility segment. All other business activities, including certain gas storage activities, water businesses, and other investments and activities are aggregated and reported as other at their respective registrant. References in this discussion to "Notes" are to the Notes to the Consolidated Financial Statements in ltem 8 of this report. ln addition, NW Holdings has reported discontinued operations results related to the pending sale of Gill Ranch Storage, LLC (Gill Ranch). NW Natural Gas Storage, LLC (NWN Gas Storage), currently an indirect wholly-owned subsidiary of NW Holdings, entered into a Purchase and Sale Agreement during the second quarter of 201 8 that provides for the sale of all membership inlerests in Gill Ranch. Gill Ranch owns a 75% interest in the natural gas storage facility located near Fresno, California known as the Gill Ranch Gas Storage Facility. Pacific Gas and Electric Company (PG&E) owns the remaining 25% interest in the Gill Ranch Gas Storage Facility. For more information, see "Results of Operations - Pending Sale of Gill Ranch Storage" below. The following is management's assessment of NW Holdings' and NW Natural's financial condition, including the principal factors that affect results of operations. The discussion covers the years ended December 31, 2018, 20'17, and2016 and refers to the consolidated results of NW Holdings, the substantial majority of which consist of the operating results of NW Natural. When significant activity exists at NW Holdings that does not exist at NW Natural, additional disclosure has been provided. NW Holdings'direct and indirect wholly-owned subsidiaries include: Northwest Natural Gas Company (NW Natural);. Northwesl Energy Corporation (Energy Corp);. NWN Gas Reserves LLC (NWN Gas Reserves); NW Natural Energy, LLC (NWN Energy);. NW Natural Gas Storage, LLC (NWN Gas Storage);. Gill Ranch Storage, LLC (Gill Ranch), which is presented as a discontinued operation; NNG Financial Corporation (NNG Financial); " KB Pipeline Company (KB); NW Natural Water Company, LLC (NWN Water);.

NW Natural Water of Washington, LLC (NWN Water of Washington);. NW Natural Water of ldaho, LLC (NWN Water of ldaho); and. Gem State Water Company, LLC (Gem State) The NGD segment includes our NW Natural local gas distribution business, NWN Gas Reserves, which is a wholly-owned subsidiary of Energy Corp, and the NGD-portion of NW Natural's Mist storage facility in Oregon. Other activities aggregated and reported as other at NW Natural include the non-NGD storage activity at Mist as well as asset management services and the appliance retail center operations. Other activities aggregated and reported as other at NW Holdings include NWN Energy's equity investment in Trail West Holding, LLC (TWH), which is pursuing the development of a proposed natural gas pipeline through lts wholly-owned subsidiary, Trail West Pipeline, LLC (TWP); NNG Financial's investment in Kelso-Beaver Pipeline (KB Pipeline); and NWN Water, which owns and continues to pursue investments in the water sector. See Note 4 for further discussion of our business segment and other, as well as our direct and indirect wholly-owned subsidiaries. NON-GAAP FINANCIAL MEASURES. ln addition to presenting the results of operations and earnings amounts in total, certain financial measures are expressed in cents per share or exclude the effects of certain items, which are non-GAAP financial measures. We present net income or loss and earnings or loss per share adjusted for certain items along with the U.S. GAAP measures to illustrate their magnitude on ongoing business and operational results. Although the excluded amounts are properly included in the determination of net income or loss and earnings or loss per share under U.S. GAAP, we believe the amount and nature of these ilems make period to period comparisons of operations difficult or potentially confusing. We use such non-GAAP financial measures to analyze our financial performance because we believe they provide useful information to our investors and creditors in evaluating our financial condition and results of operations. Our non-GAAP financial measures should not be considered a subslitute for, or superior to, measures calculated in accordance with U.S. GAAP. Reconciliations of the non-GAAP financial Exhibit 3 J.

Loss from discontinued operations, net of tax 2018 COMPAREDTO2017. NW Holdings'and NW Nalural's net income from continuing operations were $67.3 million and $68.0 million, respectively, in 2018 compared to $72.1 million and $71.7 million, respectively, in 2017 . The decrease was primarily due to the benefit associated with the TCJA deferred income tax remeasuremenlin20lT Excluding the benefit in2017 associated with the TCJA remeasurement, NW Holdings adjusted net income from continuing operations decreased $1.4 million. See the Non-GAAP reconciliations at the beginning of ltem 7 for additional information. The decrease was primarily due to the following factors, all of which were driven by activity at NW Natural:. an $8.9 million decrease in NGD segment margin primarily due to the deferral of excess revenue associated with the federal income tax rate decrease as a result of the TCJA;. a $4.3 million increase in operations and maintenance expense driven by general payroll and benefits increases as well as increases in professional services and contract labor; a $4.1 million increase in depreciation and amortization primarily due to additional capital expenditures; and a $3.3 million decrease in other income (expense), net primarily due to an increase in pension and postretirement benefit expense, partially offset by an increase in the equity portion of AFUDC; partially offset by a $20.2 million decrease in income tax expense due to the decrease in the federal income tax rate as a result of the TCJA and lower pretax earnings. 2017 comPARED To 2016. NW Holdings' and NW Natural's net income from continuing operations were $72.1 million and $71.7 million, respectively, in 2017 compared to $62.4 million and $62.8 million, respectively, in 2016. The increase included a $3.4 million benefit due to the deferred income tax balance remeasurement associated with the TCJA in 2017 and a $3.3 million pre{ax regulatory environmenlal disallowance in 2016.

See the Non-GAAP reconciliations at the beginning of ltem 7 for additional information. The increase was primarily due to the following factors, all of which were driven by activity at NW Natural:. a $16.0 million increase in NGD segment margin primarily due to customer growth and effects of colder than average weather in 2017 compared to warmer than average weather in 2016; and. a $6.9 million increase in other income (expense), net primarily due an increase in the equity portion of AFUDC; partially offset by. a $15.7 million increase in operations and maintenance expense driven by higher NGD segment payroll and benefits increases, as well as increased NGD segmenl safety equipment upgrade costs; and. a $1.0 million decrease in revenues from asset management agreements for Mist storage and transportation capacity. 32 Exhibit 3 J.

At NW Natural, we are working closely with the Oregon commission and other stakeholders on several significant items, including the best way to return benefits from the TCJA to NW Natural customers and complete its Oregon general rate case, which we filed in Decembet 2017. With regard to Washington regulation, NW Natural filed a general rate case with Washington in December 2018 and will seek to work productively with parties in an effort to conclude that case in 2019. NW Natural will continue working with the EPA and other stakeholders on an environmentally protective and cost effective clean-up for the Portland Harbor Superfund Site. Finally, we are engaged in policy discussions both in Oregon and Washington al the state and community level to build support for a constructive role for natural gas in a low-carbon future. Enable NW Natural Growth Lead in a Low-Carbon Future lntegrate and Grow our Water Businesses Nw NATURAL GROWTH. Natural gas is the preferred energy choice in NW Natural's service territory given its efficient, affordable, and reliable qualities. We are focused on leveraging these key attributes to capitalize on our region's strong economic grolvth. We continue to grow our market share in the single-family residential sector and capture new commercial customers as well as multifamily or mixed-use developments. ln addition, one of the largest and most innovative capital projects in the history of NW Natural, the North Mist Gas Storage Expansion, is expected to be completed and begin supporting the integration of renewables into the electric grid in 2019. We will continue to look for opportunities to serve and grow with our communities. LOW-CARBON PATHWAY. We are deeply committed to a clean energy fulure. lt's why NW Natural launched a low-carbon initiative to reduce emissions in the customers and communities NW Natural serves by leveraging modern pipeline systems in new ways, working closely with customers, policymakers and regulators, and embracing cutting-edge technology. NW Natural partnered with the City of Portland to bring renewable natural gas (RNG) onto its system. We expect the entire project to be operational in 2019 with several other RNG projects underway for completion this year or in 2020. To further understand the role of natural gas in a low-carbon future, NW Natural engaged a premier environmental consultant to complete a deep decarbonization study. The study outlines how natural gas can help achieve crucial emission reductions of 80% by 2050. We will continue helping our customers reduce and offset their consumption as we support the development of renewable natural gas supply and explore other cutting edge solutions to lower the carbon intensity of natural gas, such as power to gas. INTEGRATE AND GRow WATER. NW Water began its expansion into the water business more than a year ago with a focus on water sector investments that fit our conservative risk profile and core competencies. ln 20'19 we plan to close our largest acquisition to date in Sunriver, Oregon that serves approximately 9,400 water and wastewater connections. Once all outstanding transactions are closed, NW Water will serve 18,000 connections and have invested nearly $70 million in the water sector. Exhibit 3 J. Palfreyman, Falls Water Co., lnc.

NW Natural's natural gas distribution business is subject to regulation by the OPUC and WUTC with respect to, among other matters, rates and terms of service, systems of accounts, and issuances of securities by NW Natural. ln 201 8, approximately 89o/o of NGD customers were located in Oregon, with the remaining 1 1% in Washington. Earnings and cash flows from natural gas distribution operations are largely determined by rates set in general rate cases and other proceedings in Oregon and Washington. They are also affected by weather, the local economies in Oregon and Washington, the pace of customer growth in the residential, commercial, and industrial markets, and NW Natural's ability to remain price competitive, control expenses, and obtain reasonable and timely regulatory recovery of its natural gas distribution-related costs, including operaling expenses and investment costs in plant and other regulatory assets. See "Most Recent General Rate Cases"below. MIST INTERSTATE GAS STORAGE. NW Natural's interstate storage activity at Mist is subject to regulation by the OPUC, WUTC, and FERC with respect to, among other matters, rates and terms of service. The OPUC also regulates the intrastate storage services at Mist, while FERC regulates the interstate storage services at Mist. The FERC uses a maximum cost of service model which allows for gas slorage prices to be set at or below the cost of service as approved by each agency in their last regulatory filing. The OPUC Schedule 80 rates are tied to the FERC rates, and are updated whenever NW Natural modifies FERC maximum rates. OTHER. ln June 2018, NWN Gas Storage entered into a Purchase and Sale Agreement for the sale of all of its ownership interests in Gill Ranch, a natural gas storage facility located near Fresno, California, which is subject to approval by the CPUC and other customary closing conditions. See Note 18 for more information. Most Recent Rate Cases OREGON. Effective November 1, 2012,through October 31, 2018, the OPUC authorized rates to customers based on an ROE of 9.5%, an overall rate of return of 7 .78o/o, and a capital structure of 50% common equity and 507o long{erm debt. Effective November 1,2018, the OPUC authorized rales to customers based on an ROE of 9.4o/o, an overall rate of return of 7 .317o/o, and a capital structure of 50% common equity and 50% long-term debt. For add itional information, see " Reg u I ato ry Proceed i n g Updales" below. WASHINGToN. Effective January 1, 2009, the WUTC authorized rates to customers based on an ROE of '10.'lo/o and an overall rate of return of 8.4% with a capital structure of 51% common equity, 5% short{erm debt, and 44o/o long-term debt. On December 31 , 2018, NW Natural filed a general rate case in Washington requesting an ROE of 10.3o/o, an overall rate of return of 7.63%, and a capital structure ot 49.5o/o common equity, 49.5% long-term debt, and 1% short{erm debt. For additional information, see " Reg u I atory P roce edi ng Updafes" below. FERC. NW Natural is required under its Mist interstate storage certificate authority and rate approval orders to file every five years either a petition for rate approval or a cost and revenue study to change orjustify maintaining the existing rates for its interstate storage services. ln January 2018, various state parlies filed a request with the FERC to adjust the revenue requirements of public utilities to reflect the recent reduction in the federal corporate income tax rate and other impacts resulting from the TCJA. ln July 2018, the FERC issued an order finalizing its regulations regarding the effect of the TCJA. The new regulations required NW Natural to file a petition for rate approval or a cost and revenue study to reflect the new federal corporate income tax rate within thirty days of the rate effective date of NW Natural's Oregon rate case. On October 12,2018, NW Natural filed a rate petition with FERC for revised maximum cost-based rates, which incorporated the new federal corporate income tax rate. The revised rates became effective November 1, 20'18. NW Natural continuously evaluates the need for rate cases in its jurisdictions. For additional information, see "Regulatory Proceeding Updates-Rafe Case" below. Requlatorv Proceeding Updates During 2018, NW Natural was involved in the regulatory activities discussed below. INTERSTATE STORAGE AND OPTIMIZATION SHARING. NW Natural received an Order from the OPUC in March 201 5 on their review of the current revenue sharing arrangement that allocates a portion of the net revenues generated from non-NGD Mist storage services and third-party asset management services to NGD business customers. The Order required a third-party cost study to be performed . ln 2017 , a third-party consultant completed a cost study and their final report was filed with the OPUC in February 20'18. The OPUC concluded on this matter in the Oregon general rate case proceeding. For additional information, see "Oregon General Rate Case" below. HOLDING COMPANY REORGANIZATION. ln February 2017, NW Natural filed applications with the OPUC, WUTC, and CPUC for approval to reorganize under a holding company structure. ln 20'17, the OPUC and WUTC approved NW Natural's applications subject to certain restrictions or "ring-fencing" provisions applicable to NW Natural, the company that currently engages, and would continue to engage, in NGD business operations. During the second quarter of 201 8, NW Natural received approval to reorganize into a holding company structure from the CPUC. On October 1 ,2018, we completed the reorganization to a holding company structure. Effective November 1 , 2018 there are a number of conditions under the agreement with the OPUC and the WUTC related to the formation of a holding company structure. One of the conditions is that, for three years, NW Natural will be required to provide an annual $500,000 credit to Oregon customers and a $55,000 credit Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 37 of21O 35 Table of Contents to Washington customers. The first-year credit to both Oregon and Washington customers was given in conjunction with the PGA filings, with the rate adjustments commencing on November 1,2018. TAx REFoRIUI DEFERRAL. ln December 2017, NW Natural filed applications with the OPUC and WUTC to defer the overall net benefit associated with the TCJA that was enacted on December 22,2017 . Through the Oregon general rate case, in October 2018 the OPUC issued an order directing NW Natural and the other parties to the rate case to engage in further regulatory proceedings to resolve open issues with respect to the treatment of the 1O-month deferral period of benefits associated with the TCJA. On February 4, 20'19, NW Natural and the other parties to the rate case agreed upon terms by which the deferred benefits would be returned to customers via a joint stipulation filed with the OPUC. For it to be effective, the OPUC must issue an Order. See "Regulatory Proceeding Updates-Oregon General Rate Case" belowfor more information. NW Natural expects to work with the WUTC regarding the Washington deferral for the TCJA as part of the general rate case filed in Washington on December 31,20'18, and is currently deferring all amounts for the benefit of Washington customers. WATER BUSINESS. Since we initiated our water strategy in December 2017,we have entered into the following agreements which require or required regulator approval:. Salmon Valley Water Company - We received regulatory approval for this Welches, Oregon acquisition in September 201 8, and the transaction closed in November 201 8.. Falls Water Company - We received regulatory approval for this ldaho Falls, ldaho acquisition in July 20 t 8 from the IPUC and closed the transaction in September 2018.. Lehman Enterprises, lnc. and Sea View Water LLC - We received regulatory approval from the WUTC for these Whidbey lsland, Washington acquisitions in October 2018 and closed the transaction in November 2018.. Sunriver Water, LLC and Sunriver Environmental, LLC - We filed an application for regulatory approval from the OPUC for the Sunriver Water, LLC acquisition in October 2018 and anticipate receiving regulatory approval in 2019. Sunriver Environmental, LLC is not under the OPUC's jurisdiction. The transaction is expected to close in the first half of 201 9.. Spirit Lake East Water Company and Lynnwood Water - We filed an application for regulatory approval from the IPUC for these Coeur d'Alene, ldaho acquisitions in February 20'19.. Estates Water Systems lnc. and Monterra lnc - We filed an application for regulatory approval from the WUTC for these Sequim, Washington acquisitions in February 2019. The acquisitions described above are expected to, upon the closing of the Sunriver transaction, represent approximately $70 million of aggregate investment. OREGON GENERAL RATE CASE. On October 26, 201 8, the OPUC issued an order regarding NW Natural's general rate case originally filed in December 2017 and approved the following items:. Annual revenue requirement increase of $23.4 million or 3.72% over NW Natural's revenue from existing rates, which includes approximately $12.1 million that would otherwise be recovered under the conservation tariff deferral;. Capital structure of50% debt and 50% equity;. Return on equity of 9.4o/o;. Cost of capital oI7 .317o/o;. Rate base of $1.186 billion, or an increase of $300 million since the last rate case in2012;. Commencing November 1,2018, ASC 715 pensionexpenses for the qualified pension plan will be recovered through rates with an increase of $8.1 million to revenue requirement for a total of $1 1.9 million; and. The sharing of asset management revenues related to NGD business pipeline and storage assets will be 90%/10% with 90% being credited to customers. Previously customers received 67% ofthese revenues. The rate changes listed above went into effect on November 1 ,2018. ln addition to the items above, the OPUC issued an order on October 26, 20'18, to freeze NW Natural's pension balancing account as of October 31 , 2018. The order directed NW Natural and the other parties to the rate case to engage in further regulatory proceedings extending the general rate case docket to resolve open issues with respect to the recovery of the pension balancing account, and treatment of the 1 o-month deferral period benefits associated with the TCJA. On February 4, 2019, NW Natural, OPUC Staff, Oregon Citizen's Utility Board (CUB), and the Alliance of Western Energy Customers (AWEC), which comprise all of the parties to the 2018 Oregon rate case, filed with the OPUC a joint stipulation addressing remaining items related to NW Natural's pension balancing account and the return of deferred TCJA benefits to customers (Settlement). The Settlement is subject to the review and approval of the OPUC. For it to be effective, the OPUC must issue an Order, which may approve or deny the terms of the Settlement or be issued under the OPUC's own terms. Under the Settlement, the stipulating parties agree that NW Natural properly recorded the remeasurement of regulated NGD excess deferred income taxes pursuant to the effects of the TCJA, and agree that all of NW Natural's TCJA-related dockets will be resolved in accordance with the terms of the Settlement. Under the Settlement, NW Natural would return excess deferred income taxes pursuant to the TCJA as follows: (i) an annual credit to base rates of $3.4 million; (ii) a credit of $3.0 million per year for five years to sale customers; (iii) a credit to customers' benefit of $5.44 million of deferred income taxes, and $7.07 million of TCJA benefits deferred between January 1 , 201 8 and October 31 , 201 8, reflected as a reduction to NW Natural's pension balancing account, described below. As a result of these returns and credits, NW Natural's rate base is expected to increase by approximately $15.38 million, and the revenue requirement is expected to increase approximately $1.43 Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 38 of 210 36 Table of Contents million. lf NW Natural files a general rate case within five years of the date of the Order implementing the Settlement, this revenue requirement may be adjusted as part of that general rate case. As to the future operation and liming of rate recovery of amounts reflected in NW Natural's pension balancing account, under the Settlement, the stipulating parties agree that, effective October 31 , 2018, NW Natural would: (i) reduce the amount ofthe frozen pension balancing account by $10.5 million, and apply $12.51 million of the Company's deferred TCJA benefits, for a total reduction of the pension balancing account of approximately $23.01 million; and (ii) reduce the interest rate on the pension balancing account from NW Natural's authorized rate of return of 7.317 percent to 4.3 percent. NW Natural would then collect the remainder of the pension balancing account balance over ten years in a customer tariff of $7.3 million per year beginning on the rate effective date. lf the Settlement is approved, NW Natural expects to recognize an after{ax charge to earnings of approximately $6.7 million in the quarter in which an order is issued. The Settlement is subject to lhe review and approval of the OPUC with a decision and order expected in March 20'19, and new rates expected to be effective April 1, 2019. WASHINGTON GENERAL RATE CASE. On December 31 , 2018, NW Natural filed for a general rate case in the state of Washington. The requested increase, the first in approximately 10 years, is intended to recover operating costs and investments made in the Washington distribution system and is based upon the following assumptions or requests:. Capital structure ot 49.5o/o long-term debt, 1 .0% short-term debt, and 49.5olo common equity;. Return on equity of 10.3%;. Cost of capital of 7.630/o: and. Rate base of $186.5 million, an increase of $58.7 million since the last rate case. The filing also includes a proposal to return federal tax reform benefits to customers related to the TCJA. NW Natural estimates the total liability for tax reform benefits allocated to Washington customers to be approximately $20.2 million, which is comprised of a historical deferred liability of $18.1 million primarily related to property, plant, and equipment and an expected $2.1 million associated with interim lax benefits accumulated from January 1 ,2018 to November 30, 2019. NW Natural is requesting that the $18.1 million historical deferral be credited to rates in compliance with the TCJA guidance, which is currently at a rate of approximately $0.5 million annually for the first five years, and which would be reviewed and adjusted in year five for the next five years. NW Natural is requesting that the interim $2.1 million tax benefit be returned to customers over two years. ln addition, NW Natural is requesting a decoupling tariff for Washington customers, which is intended to allow the NGD business to continue encouraging customers to conserve energy without adversely affecting earnings due to reductions in sales volumes. The proposed decoupling tariff would also adjust for any deviation from normal usage, including weather. Finally, NW Natural is requesting that the WUTC review costs allocable to Washington related to environmental remediation expenses and consider a mechanism for recovery of these costs. The requested costs are estimated to be approximalely 3.32o/o of total costs associated with those sites related to serving Washington customers. NW Natural's filing will be reviewed by the WUTC and other stakeholders. The process is anticipated to take up to 1'l months. NW Natural has requested that the new rates take effect December 1 , 201 9. I]{TEGRATED RESOURCE PLAil (lRP). NW Natural files a full IRP biennially for Oregon and Washington with the OPUC and WUTC, respectively. NW Natural filed its 2018 Oregon and Washington lRPs in August 2018, and received both a letter of compliance from the WUTC and acknowledgment by the OPUC in February 2019. The lRPs included analysis of different growth scenarios and corresponding resource acquisition strategies. This analysis is needed to develop supply and demand resource requirements, consider uncertainties in the planning process, and to establish a plan for providing reliable and low cost natural gas service. DEPRECIATION STUDY. Under OPUC regulations, NW Natural is required to file a depreciation study every five years to update or justiry maintaining the existing depreciation rates. ln December 2016, NW Natural filed the required depreciation study with the OPUC. ln September 2017, the parties to the docket filed a settlement with the Commission requesting approval ofupdated depreciation rates. ln January 2018, OPUC issued an order adopting the stipulation. A corresponding docket was filed and approved in Washington for the same depreciation rates. FERC also adopted the new depreciation rates which were included in the rate petition described in Regulation and Rates - FERC above. The new depreciation rates were effective and implemented as of November 1, 2018 for Oregon, Washington, and FERC regulated customers. The new depreciation rates did not materially change NW Natural's depreciation rates and did not have a material impact to flnancial results. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 39 oI 210 37 Table of Contents Rate Mechanisms During 2018, NW Natural's approved rates and recovery mechanisms for each service area included: OR ln September 2018, NW Natural filed its annual PGA and received OPUC and WUTC approval in October 2018. PGA rate changes were effective November 1 ,20'18. Rates between states can vary due to different rate structures and mechanisms. Oregon residential customers' rates declined 2.1o/otrom the combined effect of the PGA and Oregon rate case and Washington residential customers' rates declined by 7.2o/o.ln addition, as required with the Washington PGA filing, NW Natural provided the WUTC with a full strategy implementation plan to incorporate risk-responsive hedging strategies in its natural gas procurement process. The plan calls for a flexible hedging approach that reacts to changes in market conditions as those changes occur. NW Natural expects to begin implementing risk-responsive hedging strategies for the 2019-20 PGA for its Washington gas supplies. Under the current PGA mechanism in Oregon, there is an incentive sharing provision whereby NW Natural is required to select each year an 80% deferral or a 90o/o deferral of higher or lower actual gas costs compared to estimated PGA prices, such that the impact on NW Natural's current earnings from the incentive sharing is either 20% or '10% of the difference between actual and estimated gas costs, respectively. Forthe 2017-18 and 2018-19 gas years, NW Natural selected the 90% deferral option. Under the Washington PGA mechanism, NW Natural defers 100% of the higher or lower actual gas costs, and those gas cost differences are passed on to customers through the annual PGA rate adjustment. EARNINGS TEST REVlEw. NW Natural is subject to an annual earnings review in Oregon to determine if the NGD business is earning above its authorized ROE threshold. lf NGD business earnings exceed a specific ROE level, then 33% of the amount above that level is required to be deferred or refunded to customers. Under this provision, if NW Natural selects the 80% deferral gas cost option, then NW Natural retains all earnings up to '150 basis points above the currently authorized ROE. lf NW Natural selects the 90% deferral option, then it retains all earnings up to 100 basis points above the currently authorized ROE. For the 201 7- 18 and 201 8-19 gas years, it selected the 90% deferral option. The ROE threshold is subject to adjustment annually based on movements in long-term interest rates. For calendar years 2016,2017, and 2018, the ROE threshold was 11.06%, 10.66%, and 10.48o/o, respectively. There were no refunds required for 201 6 and 2017. NW Natural does not expect a refund for 201 8 based on results, and NW Natural anticipates filing its 2018 earnings test in May 2019. cAS RESERVES. ln 201'1, the OPUC approved the Encana gas reserves transaction to provide long-term gas price protection for NGD business customers and determined costs under the agreement would be recovered on an ongoing basis through the annual PGA mechanism. Gas produced from NW Natural's interests is sold at then prevailing market prices, and revenues from such sales, net of associated operating and production costs and amortization, are included in cost of gas. The cost of gas, including a carrying cost for the rate base investment made under the original agreement, is included in NW Natural's annual Oregon PGA filing, which allows NW Natural to recover these costs through customer rates. The net Exhibit 3 J. Palfreyman, Falls Water Co., lnc.

Rate changes are established for NW Natural each year under PGA mechanisms in Oregon and Washington to reflect changes in the expected cost of natural gas commodity purchases. The PGA filings and filings coincident with the PGA include gas costs under spot purchases as well as contract supplies, gas costs hedged with financial derivatives, gas costs from the withdrawal of storage inventories, the production of gas reserves, interstate pipeline demand costs, temporary rate adjustments, which amortize balances of deferred regulatory accounts, and the removal of temporary rate adjustments effective for the previous year. Each year, NW Natural typically hedges gas prices on a portion of NW Natural's annual sales requirement based on normal weather, including both physical and financial hedges. NW Natural entered the 201 8-1 9 gas year with its forecasted sales volumes hedged al 49o/o in financial swap and option contracts and 260/o in physical gas supplies for Oregon and Washinglon. As of December 31,2018, NW Natural is also hedged in future gas years at approximately 17o/o for lhe 2019-20 gas year and between 1o/o dnd 8o/o for annual requirements over the subsequent five gas years. Hedge levels are subject to change based on actual load volumes, which depend to a certain extent on weather, economic conditions, and estimated gas reserve production. Also, gas storage inventory levels may increase or decrease with storage expansion, changes in storage contracts with third parties, variations in the heat content of the gas, and/or storage recall by NW Natural. 9.5olo 7.8o/o 5Oo/ol5oo/o 9.4o/o 7.3o/o 5Oo/ol50o/o x x x x x x x x x x x x x x X x xx 38 2018 Rate Case (effective 11t1t2018) Table of Contents investment under the original agreement earns a rate of return ln2014, NW Nalural amended the original gas reserves agreement in response to Encana's sale of its interest in the Jonah field located in Wyoming to Jonah Energy. Under the amended agreement with Jonah Energy, NW Natural has the option to invest in additional wells on a well- by-well basis with drilling costs and resulting gas volumes shared at the amended proportionate working interest for each well in which NW Natural invests. Volumes produced from the additionalwells drilled after the amended agreement are included in NW Natural's Oregon PGA at a fixed rate of $0.4725 per therm. NW Natural did not have the opportunity to participate in additional wells in 2016,20'17, or 2018. DEcoUPLlNc. ln Oregon, NW Natural has a decoupling mechanism. Decoupling is intended to break the link between earnings and the quantity of gas consumed by customers, removing any financial incentive to discourage customers' efforts to conserve energy. The Oregon decoupling mechanism was reauthorized and the baseline expected usage per customer was reset in the 201 I Oregon general rate case. This mechanism employs a use-per-customer decoupling calculation, which adjusts margin revenues to account for the difference between actual and expected customer volumes. The margin adjustment resulting from differences between actual and expected volumes under the decoupling component is recorded to a deferral account, which is included in the annual PGA filing. ln Washington, customer use is not covered by such a tariff. However, NW Natural's general rate case filed in Washington on December 31, 2018, requests that such a tariff be implemented. See "Regulatory Proceeding Updates-Wash ington General Rate Case " above. WARM. ln Oregon, NW Natural has an approved weather normalization mechanism, which is applied to residential and commercial customer bills. This mechanism is designed to help stabilize the collection of fixed costs by adjusting residential and commercial customer billings based on temperature variances from average weather, with rate decreases when the weather is colder than average and rate increases when the weather is warmer than average. The mechanism is applied to bills from December through mid-May of each heating season. The mechanism adjusts the margin component of customers' rates to reflect average weather, which uses the 2s-year average temperature for each day of the billing period. Daily average temperatures and 2S-year average temperatures are based on a set point temperature of 59 degrees Fahrenheit for residential customers and 58 degrees Fahrenheit for commercial customers. The collections of any unbilled WARM amounts due to tariff caps and floors are deferred and earn a carrying charge until collected, or returned, in the PGA the following year. This weather normalization mechanism was reauthorized in the 2012 Oregon general rate case without an expiration date. Residential and commercial customers in Oregon are allowed to opt out of the weather normalization mechanism, and as of December 31, 2018, 8% of eligible customers had opted out. NW Natural does not have a weather normalization mechanism approved for residential and commercial customers in Washington, which account for about 11% of total customers. See "Business Segments-Nafura/ G a s D i stri b ution " below. INDUSTRIAL TARIFFS. The OPUC and WUTC have approved tariffs covering NGD service to major industrial customers, which are intended to give NW Natural certainty in the level of gas supplies needed to serve this customer group. The approved terms include, among other things, an annual election period, special pricing provisions for out-of-cycle changes, and a requirement that industrial customers complete the term of their service election under NW Natural's annual PGA tariff. ENVIRONMENTAL COST DEFERRAL AND SRRM. NW NatuTaI has a SRRM through which it tracks and has the ability to recover past deferred and future prudently incurred environmental remediation costs allocable to Oregon, subject to an earnings test. Under the SRRM collection process, there are three types of deferred environmental remediation expense:. Pre-review - This class of costs represents remediation spend that has not yet been deemed prudent by the OPUC. Carrying costs on these remediation expenses are recorded at NW Natural's authorized cost ofcapital. NW Natural anticipates the prudence review for annual costs and approval of the earnings test prescribed by the OPUC to occur by the third quarter of the following year.. Post-review - This class of costs represents remediation spend that has been deemed prudent and allowed after applying the earnings test, but is not yet included in amortization. NW Natural earns a carrying cost on these amounts at a rate equal to the five-year treasury rate plus 100 basis points.. Amortization - This class of costs represents amounts included in current customer rates for collection and is generally calculated as one-fifth of the post-review deferred balance. NW Natural earns a carrying cost equal to the amortization rate determined annually by the OPUC, which approximates a short-term borrowing rate. NW Natural included $6.1 million and $7.4 million of deferred remediation expense approved by the OPUC for collection during the 201 8-1 9 and 2017 -1 I PGA years, respectively. ln addition, the SRRM also provides for the annual collection of $5.0 million from Oregon customers through a tariff rider. As it collects amounls from customers, NW Natural recognizes these collections as revenue and separately amortizes an equal and offsetting amount of the deferred regulatory asset balance through the environmental remediation operating expense line shown separately in the operating expenses section of the Consolidated Statements of Comprehensive lncome (Loss). See Note 17 for more information on our environmental matters. The SRRM earnings test is an annual review of adjusted NGD ROE compared to authorized NGD ROE. For 2018, the first ten months will be weighted at 9.5% and the last two months dl9.4o/o, reflecting the ROE change from NW Natural's most recent rate case effective November 1, 2018. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 41 ot 210 39 Table of Contents To apply the earnings test NW Natural must first determine what if any costs are subject to the test through the following calculation: Annual spend Less: $5.0 million base rate rider Prior year carry-ovell) $5.0 million insurance + interest on insurance Total deferred annual spend subject to earnings test Less: over-earnings adjustment, if any Add: deferred interest on annual spend(2) Total amount transferred to post-review(') Prior year carry-over results when the prior year amount transferred to post- review is negative. The negative amount is carried over to offset annual spend in the following year.e) Defened interest is added to annual spend to the extent the spend is recoverable. To the extent the NGD business earns at or below its authorized ROE, the total amount transferred to post-review is recoverable through the SRRM. To the extent more than authorized ROE is earned in a year, the amount transferred to post-review would be reduced by those earnings that exceed its authorized ROE. For2018, NW Natural has performed this test, which is anticipated to be submitted to the OPUC in May 2019, and no earnings test adjustment is expected for 201 8. The WUTC has also previously authorized the deferral of environmental costs, if any, that are appropriately allocated to Washington customers. This Order was effective in January 20'l 1 with cost recovery and carrying charges on amounts deferred for costs associated with services provided to Washington customers to be determined in a future proceeding. Annually, or more often if circumstances warrant, NW Natural reviews all regulatory assets for recoverability. lf NW Natural should determine all or a portion of these regulatory assets no longer meet the criteria for continued application of regulatory accounting, then NW Natural would be required to write-off the net unrecoverable balances against earnings in the period such a determination was made. PEilSION COST DEFERRAL AND PENSION BALANCING ACCOUNT. FTOff].2O1l through October20'18, the OPUC authorized a regulatory mechanism in which NW Natural deferred annual pension expenses above the amount set in rates, with recovery of these deferred amounts through the implementation of a balancing account, which included the expectation of higher and lower pension expenses in future years. During this period the mechanism permitted for NW Natural to accrue interest on the account balance at the NGD business' authorized rate of return. On October 26, 2018, the OPUC issued an order to freeze NW Natural's pension balancing account as of October 31 ,20'18. The order directed NW Natural and the other parties to the 2018 Oregon rate case to engage in further regulatory proceedings extending the general rate case docket to resolve open issues with respect to the recovery of the pension balancing account. On February 4, 201 9, NW Natural and the olher parties to the rate case filed a.ioint stipulation with the OPUC outlining a resolution to the issue. See "Regulatory Proceeding Updates-Oregon General Rate Case" above. Pension expense deferrals, excluding interest, were $10.3 million, $6.5 million, and $6.3 million in 2018, 2017 and2016, respectively. INTERSTATE STORAGE AND OPTIMIZATION SHARING. On an annual basis, NW Natural credits amounts to Oregon and Washington customers as part of a regulatory incentive sharing mechanism related to net revenues earned from Mist gas storage and asset management activities. Generally, amounts are credited to Oregon customers in June, while credits are given to customers in Washington as reductions in rates through the annual PGA filing in November. The following table presents the credits to NGD customers: ln millions 2018 2017 Oregon $ 11.7$ 11.7$ 9.4 Washington 1.0 1 .0 1.0 Business Segment - Natura! Gas Distribution (NGD) NGD margin results are primarily affected by customer growth, revenues from rate-base additions, and, to a certain extent, by changes in delivered volumes due to weather and customers' gas usage patterns because a significant portion of NGD margin is derived from natural gas sales to residential and commercial customers. ln Oregon, NW Natural has a conservation tariff (also called the decoupling mechanism), which adjusts margin up or down each month through a deferred regulatory accounting adjustment designed to offset changes resulting from increases or decreases in average use by residential and commercial customers. NW Natural also has a weather normalization tariff in Oregon, WARM, which adjusts customer bills up or down to offset changes in margin resulting from above- or below-average temperatures during the winter heating season. Both mechanisms are designed to reduce, but not eliminate, the volatility of customer bills and natural gas distribution eamings. See "Regulatory Matters-Rafe Mechanisms" above.

NGD net income was $57.5 million in 2018 compared to $60.5 million in 2017. NGD net income in2017 includes a $1.0 million loss from the remeasurement of deferred income tax balances due to the enactment of the TCJA. Excluding this item, adjusted NGD net income decreased $4.0 million, or $0.14 per share. See the NW Holdings non-GAAP reconciliations at the beginning of ltem 7 for additional information. The primary factors contributing to the decrease in adjusted NGD net income were as follows:. a $8.9 million decrease in natural gas distribution margin primarily due to:. a $7.9 million decrease due to revenues collected and deferred in association with the TCJA; partially offset by. a $4.8 million increase from customer growth; and. the majority of the remaining decrease was due to the effects of warmer than average weather in 2018 compared to colder than average weather in 2017 , partially offset by higher rates from the 2018 Oregon general rate case effective November 1 , 2018.. a $6.0 million increase in operations and maintenance expense driven largely from payroll and benefits due to increased headcount, general salary increases, and increased professional services and contract labor expense;. a$4.2 million decrease in other income (expense), net, primarily due to increases in pension non-service component costs, partially offset by increases in the equity portion of AFUDC in 201 8; and. a $4.0 million increase in depreciation expense primarily due to additional capital expenditures; partially offset by. a $20.0 million decrease in income tax expense primarily due to the reduction in the federal statutory tax rate from the TCJA and lower pretax income. Total natural gas sold and delivered in 201 8 decreased 9o/o ovet 2017 primarily due to the impact of weather that was 26% warmer than the prior period and 15o/o warmer than average. 2017 COMPARED TO 2016. NGD net income was $60.5 million in2017 compared to $54.6 million in 2016, which includes the $1.0 million loss from the remeasurement of deferred income tax balances associated with the TCJA in 2017 and the aftertax $2.0 million regulatory disallowance in 2016. Excluding these items, adjusted NGD net income increased $4.9 million, or $0.10 per share. See the Non-GAAP reconciliations at the beginning of ltem 7 for additional information. The primary factors contributing to this increase in adjusted NGD net income were as follows:. a $16.0 million increase in NGD margin primarily due to:. a $6.8 million increase from customer growth; partially offset by;. a$2.7 million decrease from gains in gas cost incentive sharing due to actual gas prices being lower than those estimated in the 2016-2017 PGA, but not by the same magnitude as in the prior period;. a portion of the remaining increase was due to the effects of colder than average weather in 2017 compared to warmer than average weather in 2016. a $2.2 million increase in other income (expense), net, primarily due to an increase in the equity portion of AFUDCin2017; partially offset by a $10.4 million increase in operations and maintenance expense driven largely from payroll and benefits due to increased headcount, general salary increases, and increased safety equipment update costs; and a $3.4 million increase in depreciation expense primarily due to additional capital expenditures. Total natural gas sold and delivered in 2017 increased 14o/o ovet 2016 primarily due to the impact of weather that was 48% colder than the prior period and 15% colderthan average. Exhibit 3 J.

The impact of weather on margin is significantly reduced through NW Natural's weather normalization mechanism in Oregon; approximately 81% of NW Natural's total customers are covered under this mechanism. The remaining customers either opt out of the mechanism or are located in Washington, which does not have a similar mechanism in place.

Under the sales service, the customer buys the gas commodity. Under the transportation service, the customer buys the gas commodity directly from a third-party gas marketer or supplier. The NGD gas commodity cost is primarily a pass-through cost to customers; therefore, NGD profit margins are not materially affected by an industrial customer's decision to purchase gas from third parties. lndustrial and large commercial customers may also selecl between firm and interruptible service options, with firm services generally providing higher profit margins compared to interruptible services. To help manage gas supplies, industrial tariffs are designed lo provide some certainty regarding industrial customers'volumes by requiring an annual service election which becomes effective November 1, special charges for changes between elections, and in some cases, a minimum or maximum volume requirement before changing options.

Other NGD Revenues Other NGD revenues include miscellaneous fee income as well as regulatory revenue adjustments, which reflect current period deferrals to and prior year amortizations from regulatory asset and liability accounts, except for gas cost deferrals which flow through cost of gas. Decoupling and other regulatory amortizations from prior year deferrals are included in revenues from residential, commercial, and industrial firm customers. Exhibit 3 J.

Cost of Gas Cost ofgas as reported by the NGD segment includes gas purchases, gas withdrawn from storage inventory, gains and losses from commodity hedges, pipeline demand costs, seasonal demand cost balancing adjustments, regulatory gas cost deferrals, gas reserves costs, and company gas use. The OPUC and WUTC generally require natural gas commodity costs to be billed to customers at the actual cost incurred, or expected to be incurred. Customer rates are set each year so that if cost estimates were met the NGD business would not earn a profit or incur a loss on gas commodity purchases; however, in Oregon we have the incenlive sharing mechanism described under "Regulatory Matters- Rate Mechanisms-Purchase d Gas Adjustment" above. ln addition to the PGA incentive sharing mechanism, gains and losses from hedge contracts entered into after annual PGA rates are effective for Oregon customers are also required to be shared and therefore may impact net income. Further, NW Natural also has a regulatory agreement whereby it earns a rate of return on its investment in the gas reserves acquired under the original agreement with Encana and includes gas from the amended gas reserves agreement at a fixed rate of$0.4725 pertherm, which are also reflected in NGD margin. See "Application of Critical Accounting Policies and Estimates-Accounting for Derivative Instruments and Hedging Activlfies" below. compared to warmer than average weather in 2016, and customer growth. The effect on net income from NW Natural's gas cost incentive sharing mechanism resulted in a slight margin loss in 20't 8 and margin gains of $t.2 million and $4.0 million for2017 and 2016, respectively. ln 2018, actual prices closely aligned with estimated prices included in customer rates. ln 2017 and 2016, actual prices were lower than the estimated prices included in customer rates due to warmer than average weather nationally, which resulted in lower national natural gas commodity prices. For a discussion of the gas cost incentive sharing mechanism, see "Regulatory Matters-Rate Mechanisms-Purchased Gas Adjustment" above. Other Other activities aggregated and reported as other at NW Natural include the non-NGD storage activity at Mist as well as asset management services and the appliance retail center operations. Other activities aggregated and reported as other at NW Holdings include NWN Energy's equity investment in Trail West Holding, LLC (TWH), which is pursuing the development ofa proposed natural gas pipeline through its wholly-owned subsidiary, Trail West Pipeline, LLC (TWP); NNG Financial's investment in Kelso-Beaver Pipeline (KB Pipeline); and NWN Water, which owns and continues to pursue investments in the water sector. See Note 4 for further discussion of our business segment and other, as well as our direct and indirect wholly-owned subsidiaries, and Note 13 for further details on our investment in TWH. At Mist, NW Natural provides gas storage services to customers in the interstate and intrastate markets using storage capacity that has been developed in advance of NGD customers' requirements. Pre{ax income from gas storage at Mist and asset management services is subject to revenue sharing with NGD customers. Under this regulatory incentive sharing mechanism, NW Natural retains 80% of pre-tax income from Mist gas storage services and asset management services when the underlying costs of the capacity being used are not included in NGD business rates. The remaining 20% is crediled to a deferred regulatory account for credit to NGD customers.

Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 47 of 210 Table of Contents 20{7 COMPARED TO 2016, Other income (expense), net, increased $6.9 million and $6.8 million at NW Holdings and NW Natural, respectively, primarily due to the January 2016 Order from the OPUC, which resulted in a pretax $2.8 million interest disallowance in 2016, an increase of $2.7 million in the equity portion of AFUDC, and $0.8 million in higher gains from company-owned life insurance. ln addition to fluctuations in other income (expense), net reported above, trom20ll through October 31, 2018, NW Natural had OPUC approval to defer certain pension costs in excess of what was recovered in customer rates, with the majority of such costs being non-service component costs reflected within other income (expense), net. This pension cost deferral was recorded to a regulatory balancing account, which stabilized the amount ofother income (expense), net each year. Total pension cost deferrals, excluding interest, were $10.3 million, $6.5 million, and $6.3 million forthe years ended December 31 , 20'18,2017 and 2016, respectively. As a result, increased pension costs had a minimal effect on other income (expense), net in 2018, 2017, and 20'16, with the increase principally related to the costs allocated to NW Natural's Washington operations, which were not covered by the pension balancing account. On October 26, 2018, the OPUC issued an order to freeze NW Natural's pension balancing account as ofOctober 31,2018. The order directed NW Natural and the other parties to the rate case to engage in further regulatory proceedings extending the general rate case dockel to resolve open issues with respect to the recovery of the pension balancing account.

Pendinq Sale of Gill Ranch Storaoe On June 20,2018, NWN Gas Storage, a wholly owned subsidiary of NW Holdings, entered into a Purchase and Sale Agreement (the Sale Agreement) that provides for the sale by NWN Gas Storage of all of its membership interests in Gill Ranch. Gill Ranch owns a 75% interest in the natural gas storage facility located near Fresno, California known as the Gill Ranch Gas Storage Facility. PG&E owns the remaining 25% interest in the Gill Ranch Facility. ln the Sale Agreement, NWN Gas Storage makes representations and warranties concerning, among other lhings, Gill Ranch, the Gill Ranch Facility and Gill Ranch's business and contractual relationships, and agrees to cause Gill Ranch to conduct its business and maintain its properties in the ordinary course, consistent with material agreements and past practice. The Sale Agreement provides for an initial cash purchase price of $25.0 million (subject to a working capital adjustment), plus potential additional payments to NWN Gas Storage of up to $26.5 million in the aggregate if Gill Ranch achieves certain economic performance levels for the first three full gas storage years (April 1 of one year through March 31 of the following year) occurring after the closing and the remaining portion of the gas storage year during which the closing occurs. The closing of the transaction is subject to approval by the CPUC, other customary closing conditions and covenants, including the requirement that all of the representations and warranties be true and correct as of the closing date except, as would not, in the case of certain representations and warranties, be reasonably expected to have a material adverse effect on Gill Ranch. The agreement is subject to termination by either party if the transaction has not closed by June 20, 2019, subject to automatic extension for six months if the CPUC has not issued an order approving the transaction by lhat date. ln July 2018, Gill Ranch filed an application with the CPUC for approval of this transaction. On February 14,2019, the active parties to the CPUC proceeding filed a settlement agreement with the CPUC. The CPUC is expected to rule on the settlement agreement within 90 days of its filing, but may grant further time for public comment. We expect an order on this matter by the end of June. On January 29, 2019, PG&E filed voluntary petitions for relief under chapter 11 bankruptcy. Although we do not currently anticipate that the PG&E filing will affect the sale of Gill Ranch, we cannot fully predict the course of the bankruptcy proceedings or the impact on the sale and will continue to monitor the situation closely. We will continue to seek to close the transaclion in the first half of 2019. The results of Gill Ranch Storage have been determined to be discontinued operations and are presented separately, net oftax, from the results of continuing operations of NW Holdings for all periods presented. See Note 18 for more information on the Sale Agreement and the results of our discontinued operations. The CPUC regulates Gill Ranch under a market-based rate model which allows for the price of storage services to be set by the marketplace. The CPUC also regulates the issuance of securities, system of accounts, and regulates intrastate storage services. The California Department of Oil Gas and Geothermal Resources (DOGGR) regulations for gas storage wells were finalized in June 2018, and the U.S. Department of Transportation's Pipeline and Hazardous Materials Safety Administration (PHMSA) proposed new federal regulations for underground natural gas storage facilities, which are expected to be finalized during 2019 and increase costs for all storage providers. NW Holdings will continue to monitor and assess the new regulations until the sale is complete, which is expected in 2019. Short-term liquidity for Gill Ranch is supported by cash balances, internal cash flow from operations, equity contributions from its parent company, and, if necessary, additional external financing. Capital Structure One of our long-term goals is to maintain a strong and balanced consolidated capital structure, while maintaining a long{erm target capital structure at NW Natural of 50% common stock and 50% long- term debt to align to allocations prescribed by NW Natural's regulators. When additional capital is required, debt or equity securities are issued depending on both the target capital structure and market conditions. These sources of capital are also used to fund long{erm debt retirements and short{erm commercial paper maturities. See "Ligurdlfy and Capital Resources" below and Note 8. Achieving ourtarget capital structure and maintaining sufficient liquidity to meet operating requirements are necessary to maintain attractive credit ratings and provide access to capital markets at reasonable costs. NW Holdings'consolidated capital structure was as follows December 31 2018 2017 Common stock equity Long{erm debt Shortterm debt, including cunent maturities of long{erm debt Total 44.4o/o 41 .1 14.5 47.1o/o 43.3 9.6 100 0%100.0olo Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 49 of21O 47 FINANCIAL CONDITION Table of Contents NW Natural's consolidated capital structure was as follows: December 31, 2018 requirements for dividends in excess of 5% of NW Natural's retained earnings. Additionally, if NW Natural's common equity (excluding goodwill and equity associated with non-regulated assets), on a preceding or projected 13-month average basis, is less than 46% of NW Natural's capital structure (common equity and long-term debt excluding imputed debt or debt-like lease obligations), NW Nalural is required to notify the OPUC, and if the common equity ratio falls below 44%, file a plan with the OPUC to restore its equity ratio to 44%. This condition is designed to ensure NW Natural continues to be adequately capitalized under lhe holding company structure. Under the WUTC order, the average common equity ratio must not exceed 56%. At December 31 ,2018, NW Natural satisfied the ring-fencing provisions described above. Nw HoLDINGS DlvlDENo POLlcY. Quarterly dividends have been paid on common stock each year since NW Holdings' predecessor's stock was first issued to the public in 1951. Annual common stock dividend payments per share, adjusted for stock splits, have increased each year since t 956. The declarations and amount of future dividends to shareholders will depend upon earnings, cash flows, financial condition, NW Natural's ability to pay dividends to NW Holdings and other factors. The amount and timing of dividends payable on common stock is at the sole discretion of the NW Holdings Board of Directors. Based on several factors, including current cash reserves, committed credit facilities, its ability to receive dividends from its operating subsidiaries, in particular NW Natural, and an expected ability to issue long-term debt and equity securities in the capital markets, NW Holdings believes its liquidity is sufficient to meet anticipated near-term cash requirements, including all contractual obligations, investing, and financing activities as discussed in"Contractual Obligations and Cash F/ows"below. Natural Gas Distribution Segment For the NGD business segment, short-term borrowing requirements typically peak during colder winter months when the NGD business borrows money to cover the lag between natural gas purchases and bill collections from customers. Short-term liquidity for the NGD business is primarily provided by cash balances, internal cash flow from operations, proceeds from the sale of commercial paper notes, as well as available cash from multi-year credit facilities, short-term credit facilities, company- owned life insurance policies, the sale of long-term debt, and equity contributions from NW Holdings. NW Natural's long-term debt and contributions from NW Holdings are primarily used to finance NGD capital expenditures, refinance maturing debt, and provide temporary funding for other general corporate purposes of the NGD business. Based on NW Natural's current debt ratings (see "Credit Ratings" below), it has been able to issue commercial paper and long-term debt at attractive rates and has not needed to borrow or issue letters of credit from its back-up credit facility. ln the event NW Natural is not able to issue new debt due to adverse market conditions or other reasons, NW Nalural expects lhat near-term liquidity needs can be met Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 50 of21O 2017 Common stock equity Long{erm debt Short-term debt, including current maturities of long{erm debt Total 42.2 42.9o/o 14.9 47.10k 43.3 9.6 100.0olo 100.0olo During 2018, changes to NW Holdings'and NW Natural's capital structures were primarily due to increases in short term debt at NW Natural partially offset by lower net proceeds from long-term debt activity at NW Natural. See further discussion below in "Cash Flows -Financing Activities". Liquidity and Capital Resources At December 31, 201 8 and December 31 ,2017 , NW Holdings had approximately $12.6 million and $3.5 million, and NW Natural had approximately $7.9 million and $3.1 million of cash and cash equivalents, respectively. ln order to maintain sufficient liquidity during periods when capital markets are volatile, NW Holdings and NW Natural may elect to maintain higher cash balances and add short term borrowing capacity. NW Holdings and NW Natural may also pre-fund their respective capital expenditures when long-term fixed rate environments are attractive. NW Holdinqs For NW Holdings, short-term liquidity is primarily provided by cash balances, dividends from its operating subsidiaries, in particular NW Natural, available cash from a multi-year credit facility, and short-term credit facilities. NW Holdings also has a universal shelf registration statement filed with the SEC for the issuance of debt and equity securities. NW Holdings long-term debt, if any, and equity issuances are primarily used to provide equity contributions to NW Holdings'operating subsidiaries for operating and capital expenditures and other corporale purposes. NW Holdings' issuance of securities is not subject to regulation by state public utility commissions, but the dividends from NW Natural to NW Holdings are subject to regulatory ring-fencing provisions. As part of the ring-fencing conditions agreed upon with the OPUC and WUTC in connection with the holding company reorganization, NW Natural may not pay dividends or make distributions to NW Holdings if NW Natural's credit ratings and common equity ratio fall below specified levels. lf NW Natural's long term secured credit ratings are below A- for S&P and A3 for Moody's, dividends may be issued so long as NW Natural's common equity ratio is 45% or more. lf NW Natural's long term secured credit ratings are below BBB for S&P and Baa2 for Moody's, dividends may be issued so long as NW Natural's common equity ratio is 46% or more. Dividends may not be issued if NW Natural's long-term secured credit ratings are BB+ or below for S&P or Ba1 or below for Moody's, or if NW Natural's common equity ratio is below 44ol0. ln each case, common equity ratios are determined based on a preceding or projected 13-month average. ln addition, there are certain OPUC notice 48 Table of Contents using internal cash flows, issuing commercial paper, receiving equity contributions from NW Holdings, or, for the NGD segment, drawing upon a committed credit facility. NW Natural also has a universal shelf registration statement filed with the SEC for the issuance of secured and unsecured debt securities. As of December 31 , 201 8, NW Natural has Board authorization to issue up to $325 million of additional FMBs and OPUC approval to issue up to $25 million of additional long-term debt for approved purposes. ln the event senior unsecured long-term debt ratings are downgraded, or outstanding derivative positions exceed a certain credit threshold, counterparties under derivative contracts could require NW Natural to posl cash, a letter of credit, or other forms of collateral, which could expose NW Natural to additional cash requirements and may trigger increases in short-term borrowings while in a net loss position. NW Natural was not required to post collateral at December 31, 2018. However, if the credit risk-related contingent features underlying these contracts were triggered on December 31, 2018, assuming longterm debt ratings dropped to non-investment grade levels, NW Natural could have been required to post $4.5 million in collateral with our counterparties. See "Credft Rafrngs" below and Note 15. Other items that may have a significant impact on NW Natural's liquidity and capital resources include NW Natural's pension contribution requirements and environmental expenditures. PEilSION COilTRIBUTION. NW Natural expects to make contributions to its company-sponsored defined benefit plan, which is closed to new employees, over the next several years until the plan is fully funded under the Pension Protection Act rules, including the rules issued under the Moving Ahead for Progress in the 21 st Century Act (MAP-21 ) and the Highway and Transportation Funding Act of 20't4 (HATFA). See "Application of Critical Accounting Policies-Acco unting for Pensions and P o stre ti re m e n t Benefits" bel ow. BoNUS DEPRECIATIoN. Fifty perc€nt bonus depreciation was available for a large portion of our capital expenditures in 2016 and 2017 for both federal and Oregon taxes. This reduced taxable income and provided cash flow benefits. However, due to the enactment ofthe TCJA on December 22, 2017, bonus depreciation is eliminated for regulated NGD-business property acquired afler December 31 ,2017 . Accordingly, we do not anticipate similar cash flow benefits related to bonus depreciation in the future. ENVIRONMENTAL EXPENDITURES. NW Natural expects to continue using cash resources to fund environmental liabilities. ln 2015, NW Natural received an Order from the OPUC regarding the SRRM mechanism and began recovering amounts through NGD business rates in November 2015. ln addition, the OPUC issued a subsequent Order regarding SRRM implementation in January 2016. See Note 17, and "Results of Operations-Regulatory Matters-E viro n me nta l Cosfs" above. Based on several factors, including current credit ratings, NW Natural's commercial paper program, current cash reserves, committed credit facilities, and an expected ability to issue long-term debt and receive equity contributions from NW Holdings, NW Natural believes its liquidity is sufficient to meet anticipated near{erm cash requirements, including all contractual obligations, investing, and financing activities as discussed in "Contractua| Ob|igations" and "Cash F/ows" below. Nw NATURAL DIVIDEND POLICY. The declarations and amount of future dividends to NW Holdings will depend upon earnings, cash flows, financial condition, the satisfaction of OPUC and WUTC regulatory ring- fencing restrictions, and other factors. The amount and timing of dividends payable on common stock is subject to approval of the NW Natural Board of Directors. OFF-BALANCE SHEET ARRANGEITIENTS. Except for certain lease and purchase commitments, NW Holdings and NW Natural have no material off-balance sheet financi n g arra ngements. See " Conlractu al Obl ig ati on s" below. ln October 2017, NW Natural entered into a 20-year operating lease agreement for a new headquarters location in Portland, Oregon. The existing headquarters lease expires in 2020 and after an extensive search and evaluation process with a focus on seismic preparedness, safety, reliability, least cost to customers and a continued commitment to NW Natural's employees and the communities NW Natural serves, NW Natural executed a new lease for suitable commercial office space in Portland, Oregon. Payments under the lease are expected to commence in 2020 and total estimated base rent payments over the life of the lease are approximately $160 million. NW Natural has the option to extend the term of the lease for two additional seven-year periods. Additionally, the lease was analyzed in consideration of build-to-suit lease accounting guidance with the conclusion that NW Natural is the accounting owner of the asset during construction. As a result, NW Natural recognized $25.5 million and $0.5 million during 2018 and 20'17 , respectively, in property, plant and equipment and an obligation in other non-current liabilities for the same amount on its consolidated balance sheet. These accounting transactions are non-cash in nature, and as such, are not included in the cash flow analysis and capital expenditures forecasts below, and have no impact on short{erm liquidity. When the new lease accounting standard became effective for NW Holdings and NW Natural in 2019, the associated build-to-suit asset and liability were de-recognized in accordance with the new standard. See Note 2 for more information on the impacts of the new lease standard. Exhibit 3 J. Palfreyman, Falls Water Co., lnc.

See Note 9.(') Gas purchases include contracts which use price formulas tied to monthly index prices. The commitment amounts presented incorporate the December 2018 first of month index price for each supply basin from which gas is purchased. For a summary of gas purchase and gas pipeline capacity commitments, see Note 16.(3) Other purchase commitments primarily consist of remaining balances under existing purchase orders. timing of these payments are uncertain; however, these payments are unlikely to all o@ur in the next '12 months.o Short- and long-term obligations include short- and long{erm debt obligations and other immaterial liabilities. ln addition to known contractual obligations listed in the above table, NW Natural has also recognized liabilities for future environmental remediation or action. The exact timing of payments beyond 12 months with respect to those liabilities cannot be reasonably estimated due to numerous uncertainties surrounding the course of environmental remediation and the preliminary nature of site investigations. See Note 17 fot a further discussion of environmental remediation cost liabilities. At December 31, 2018, 635 of NW Natural's natural gas distribution employees were members of the Office and Professional Employees lnternational Union (OPEIU) Local No. 11. ln May 2014, our union employees ratified a new labor agreement (Joint Accord) that expires on November 30, 201 9, and thereafter from year to year unless either party serves notice of ils intent to negotiate modifications to the collective bargaining agreement. The remaining terms of Joint Accord include the following items: a scheduled 3% wage increase effective December 1 each year with the potential for up to an additional 3Yo per year based on wage inflation at or above 4o/o.fhe Joint Accord also maintains competitive health benefits, including a 15o/olo 20% premium cost sharing by employees, a 401(k) contribution of 4% for employees hired after our pension plan was closed on December 31 , 2009, and a 401 (k) match of 50% of the first 6% of savings, and other flexibility provisions benefiting the Company. Short-Term Debt The primary source of short{erm liquidity for NW Holdings is cash balances, dividends from its operating subsidiaries, in particular NW Natural, available cash from a multi-year credil facility, and short-term credit facilities it may enter into from time to time. The primary source of shortterm liquidity for NW Natural is from the sale of commercial paper and bank loans. NW Holdings and NW Natural have separate commercial paper programs and separate bank facilities. ln addition to issuing commercial paper or bank loans to meet working capital requirements, including seasonal requirements to finance gas purchases and accounts receivable, short-term debt may also be used to temporarily fund capital requirements. For NW Natural, commercial paper and bank loans are periodically refinanced through the sale of long-term debt or equity contributions from NW Holdings. Commercial paper, when outstanding, is sold through two commercial banks under an issuing and paying agency agreement and is supported by one or more unsecured revolving credit facilities. See "Credit Agreements" below. At December 31, 20'18 and 2017 , NW Holdings had short-term debt outstanding of $217.6 million and $54.2 million, respectively, and NW Natural had short-term debt outstanding of $217.5 million and $54.2 million, respectively.

Credit Agreements NW Holdings ln October 2018, NW Holdings entered into a $1 00 million credit agreement, with a feature that allows it to request increases in the total commitment amount, up to a maximum of $150 million. The maturity date of the agreement is October 2,2023, with available extension of commitments for two additional one-year periods, subject to lender approval. All lenders under the NW Holdings credit agreement are major financial institutions with committed balances and investment grade credit ratings as of December 31, 2018 as follows: ln millions Lender rating, by category Loan Commilment NW Natural ln October 2018, NW Natural entered into a new multi-year credit agreement for unsecured revolving loans totaling $300 million, with a feature that allows NW Natural to request increases in the total commitment amount, up to a maximum of $450 million.

The NW Natural credit agreement permits the issuance of letters of credit in an aggregate amount of up to $60 million. The principal amount of borrowings under the credit agreement is due and payable on the maturity date. There were no outstanding balances under this credit agreement or the prior credit agreement at December 31, 2018 or 2017 . The credit agreement requires NW Natural to mainlain a consolidated indebtedness to total capitalization ratio of 70o/o or less. Failure to comply with this covenant would entitle the lenders to terminate their lending commitments and accelerate the maturity of all amounls outstanding. NW Natural was in compliance with this covenant at December 31, 2018 and 2017, with consolidated indebtedness to total capitalization ratios of 57 .1o/o and 52.9%, respectively. The agreement also requires NW Natural to maintain credit ratings with S&P and Moody's and notify the lenders of any change in NW Natural's senior unsecured debt ratings or senior secured debt ratings, as applicable, by such rating agencies. A change in NW Natural's debt ratings by S&P or Moody's is not an event of default, nor is the maintenance of a specific minimum level of debt rating a condition of drawing upon the credit agreement. Rather, interest rates on any loans outstanding underthe agreement are tied to debt ratings and therefore, a change in the debt rating would increase or decrease the cost of any loans under the credit agreement when ratings are changed.

The credit agreement requires NW Holdings to maintain a consolidated indebtedness to total capitalization ratio of 70% or less. Failure to comply with this covenant would entitle the lenders to terminate their lending commitments and accelerate the maturity of all amounts outstanding. NW Holdings was in compliance with this covenant at December 31 ,2018, with a consolidated indebtedness to total capitalization ratio of 55.6%. The agreement also requires NW Holdings to maintain debt ratings (which are defined by a formula using NW Natural's credit ratings in the event NW Holdings does not have a credit rating) with Standard & Poor's (S&P) and Moody's lnvestors Service, lnc. (Moody's) and notify the lenders of any change in its senior unsecured debt ratings or senior secured debt ratings, as applicable, by such rating agencies.

Table of Contents Credit Ratings NW Holdings does not currently maintain ratings with S&P or Moody's. NW Natural's credit ratings are a factor of liquidity, potentially affecting access to the capital markets including the commercial paper market. NW Natural's credit ratings also have an impact on the cost of funds and the need to post collateral under derivative contracts.

NW Natural was in compliance with both of these ring-fencing provisions as of December 31, 2018. NW Natural may file a voluntary petition for bankruptcy only if approved unanimously by the Board of Directors of NW Natural, including the independent director, and by the holder of the preferred share. The significant drivers of changes in cash provided by operating activities discussed below apply to both NW Holdings and NW Natural. 2018 COMPAREOTO 2017. The significant factors contributing to the $37.9 million and $33.0 million decreases in NW Holdings and NW Natural cash flow provided by operating activities, respectively, were as follows:. a decrease of $31.5 million in cash flow benefits from changes in deferred gas cost balances primarily due to higher gas prices in the fourth quarler of 2018 and lower current year PGA rates reflecting over-collections of certain fixed costs from customers in the prior year when weather was colder than average;. a decrease of $1 2.6 million due lo $27 .4 million income taxes paid in 201 8 due to the elimination of bonus depreciation as a result of the TCJA, compared to income taxes paid of $14.8 million in 2017; partially offset by. a net increase of $1 0.2 million from changes in working capital related to receivables, inventories, and accounts payable reflecting warmer than average weather in 2018 compared to the prior period; and. an increase of $3.9 million due to a decrease in contributions paid to qualified defined benefit pension plans 2017 COMPARED TO 2016, The significant factors contributing to the $15.4 million and $15.7 million decreases in NW Holdings and NW Natural cash flows provided by operating activities, respectively, were as follows:. a decrease of $21.9 million due to $14.8 million income taxes paid in 2017 compared to a refund of $7.2 million in 2016 as a result of the enactment of bonus depreciation in December 2015;. a decrease of $5.0 million due to an increase in contributions paid to qualified defined benefit pension plans; and. a net decrease of $12.2 million from changes in working capital related to receivables, inventories, and accounts payable reflecting colder than average weather in 2017 compared to the prior period; partially offset by Exhibit 3 J.

During the year ended December 31 , 201 8, NW Natural contributed $15.5 million to its qualified defined benefit pension plan, compared to $19.4 million ior 2017 and $14.5 million for 2016. The amount and timing of future contributions will depend on market interest rates and investment returns on the plans' assets. See Note 9. Bonus depreciation of 50% was available for a large portion of capital expenditures for federal and Oregon purposes in 201 6 and 201 7. This reduced ourtaxable income and provided cash flow benefits. Bonus depreciation tor 20'15 was not enacted until December 18, 2015, and was extended retroactively back to January 1 , 201 5 of the respective year. As a result, estimated income tax payments were made throughout 2015 without the benefit of bonus depreciation for the year. This delayed the cash flow benefit of bonus depreciation until refunds could be requested and received. We received refunds of federal income tax overpayments of $7.9 million during 2016. As a result of the enactment of the TCJA on December 22, 2017, bonus depreciation was eliminated for NGD business property acquired afler December 31 ,2017. Accordingly, we do not anticipate similar cash flow benefits related to bonus depreciation in the future. We have lease and purchase commitments relating to our operating activities thal are financed with cash flows from operations. For information on cash flow requirements related to leases and other purchase commitments, see "Financlal Condition-Co ntractual Obligations" above and Note 16. lnvesting Activities lnvesting activity highlights include: NW Holdings ln millions 2018 2017 2016 Mist Gas Storage Expansion Project as well as customer groMh, system reinforcement, technology, and facilities. NW NATURAL 2018 COMPARED TO 2017, The $24.3 million increase in cash used in investing activities was primarily due to NW Natural's initial cash contribution of $20 million to its then subsidiary, and now parent, NW Holdings, in addition to continued capital expenditures primarily related to NW Natural's North Mist Gas Storage Expansion Project as well as customer growth, system reinforcement, technology, and facilities. 2017 CoMPARED To 2016. The $77.6 million increase in cash used in investing activities was primarily due to higher capital expenditures primarily related to NW Natural's North Mist Gas Storage Expansion Project as well as customer growth, system reinforcement, technology and facilities. The operating subsidiaries of NW Holdings invest in capital expenditures to maintain and enhance the safety and integrity of their distribution systems, to expand the reach or capacity of those assets, and improve the efficiency of operations. CAPITAL EXPENDITURES. NW Holdings'largest subsidiary, NW Natural, expects to make a significant level of investments in its NGD segment in 20 1 I and through 2023. Over the five-year period from 201 9 to 2023, the NGD segment is expected to invest $820 to $910 million in capital expenditures to support system reliability, customer growth, and operate effective technology for the business. ln 2019, NW Natural anticipates several significant projects for the NGD segment, including completing the replacement of end of life equipment at the Mist gas storage facility, and renovating several resource facilities across NW Natural's service territory. Projects in 2019 also include leasehold improvements and technology for the new headquarters in Portland, Oregon and the completion of the North Mist gas storage expansion project. NW Holdings'wholly-owned water subsidiaries expect to invest in their facilities to support growth and upgrade their systems with $30 to $40 million expected to be invested from 2019 1o2023. NW Holdings expects an immaterial amount of non-NGD capilal investments for Gill Ranch and other activities in 2019 and through 2023. lnvestments in our infrastructure during and after 201 9 beyond the amounts provided below will depend largely on additional regulations, growth, and expansion opportunities.

NW NATURAL 2018 COMPARED TO 2017. The $62.4 million increase in cash provided by financing activities was primarily due to increases in short term debt issuances of $162.4 million, partially offset by $107.0 million lower net proceeds from long-term debt activity in 20'18. NW Natural cash provided by financing activities was $12.0 million higher in comparison to NW Holdings primarily due to the payment of the November 1 5, 2018 dividend to NW Holdings shareholders using NW Holdings funds. 2017 coirlPARED TO 20l6.The $93.6 million increase in cash provided by financing activilies was primarily due to $217.6 million lower repayments of shortterm debt compared to the prior period, partially offset by $65 million lower net proceeds from long-term debt activity in 2017 and $52.8 million of common stock proceeds in 2016. Pension Cost and Fundino Status of Qualified Retirement Plans NW Natural's pension costs are determined in accordance with accounting standards for compensation and retirement benefits. See "Application of Critical Accounting Policies and Estimates - Accounting for Pensions and Postretirement Benefits" below. Pension expense for NW Natural's qualified defined benefit plan, which is allocated between operations and maintenance expenses, capital expenditures, and through October 31, 20"18, the deferred regulatory balancing account, totaled $20.7 million in 2018, an increase of $2.6 million from 2017. The fair market value of pension assets in this plan decreased to $257.8 million at December 31 , 2018 from $287.9 million at December 31 , 2U7.fhe decrease was due to a loss on plan assets of $25.9 million and benefit payments of $19.7 million, offset by $15.5 million in employer contributions. Contributions made to NW Natural's company-sponsored qualified defined benefit pension plan are based on actuarial assumptions and estimates, tax regulations, and funding requirements under federal law. The qualified defined benefit pension plan was underfunded by $162.4 million at December 31, 2018. NW Natural plans to make contributions during 2019 of $1 'l .0 million. See Note I for further pension disclosures. Continqent Liabilities Loss contingencies are recorded as liabilities when it is probable that a liability has been incurred and the amount of the loss is reasonably estimable in accordance with accounting standards for contingencies. See"Application of Citical Accounting Policies and Estimates" below. At December 31 ,2018, NW Natural's total estimated liability related to environmental sites was $128.7 million. See Note 17 and "Results of Operations-Regulatory Matters-Rate Mechanisms- E nvi ron me ntal Cosfs" above. NW Holdings is not currently party to any direct claims or litigation, though in the future it may be subject to claims and litigation arising in the ordinary course of business. Exhibit 3 J.

APPLICATION OF CRITICAL ACCOUNTING POLICIES AND ESTIMATES ln preparing financial statements in accordance with U.S. GAAP, management exercises judgment in the selection and application of accounting principles, including making estimates and assumptions that affect reported amounts of assets, liabilities, revenues, expenses, and related disclosures in the financial statements. Management considers critical accounting policies to be those which are most important to the representation of financial condition and results of operations and which require management's most difficult and subjective or complex judgments, including accounting estimates that could result in materially different amounts if reported under different conditions or used different assumptions. Our most critical estimates and judgments for both NW Holdings and NW Natural include accounting for:. regulatory accounting;. revenue recognition;. derivative instruments and hedging activities;. pensions and postretirement benefits;. income taxes;. environmental contingencies; and. impairment of long-lived assets and goodwill. Management has discussed its current estimates and judgments used in the application of critical accounting policies with the Audit Committees of the Boards of NW Holdings and NW Natural. Within the conlext of critical accounting policies and estimates, management is not aware of any reasonably likely events or circumstances that would result in materially different amounts being reporled. Regulatory Accounting The NGD segment is regulated by the OPUC and WUTC, which establish the rates and rules governing services provided to customers, and, to a certain extent, set forth special accounting treatment for certain regulatory transactions. ln general, the same accounting principles as non-regulated companies reporting under U.S. GAAP are used. However, authoritative guidance for regulated operations (regulatory accounting) requires different accounting treatment for regulated companies to show the effects of such regulation. For example, NW Natural accounts for the cost of gas using a PGA deferral and cost recovery mechanism, which is submitted for approval annually to the OPUC and WUTC. See "Results of Operations-Regulatory Malters- Rate Mechanisms-Purchase d Gas Adjustment" above. There are other expenses and revenues that the OPUC or WUTC may require NW Natural to defer for recovery or refund in future periods. Regulatory accounting requires NW Natural to account for these types of deferred expenses (or deferred revenues) as regulatory assets (or regulatory liabilities) on the balance sheet. When the recovery of these regulatory assets from, or refund of regulatory liabilities to, customers is approved, NW Natural recognizes the expense or revenue on the income statement at the same time the adjustment to amounts included in rates charged to customers The conditions that must be satisfied to adopt the accounling policies and practlces of regulatory accounting include:. an independent regulator sets rates;. the regulator sets the rates to cover specific costs of delivering service; and. the service territory lacks competitive pressures to reduce rates below the rates set by the regulator. Because NW Natural's NGD operations satisfy all three conditions, NW Natural continues to apply regulatory accounting to NGD operations. Future accounting changes, regulatory changes, or changes in the competitive environment could require NW Natural to discontinue the application of regulatory accounting for some or all of our regulated businesses. This would require the write-off of those regulatory assets and liabilities that would no longer be probable of recovery from or refund to customers. Based on current accounting and regulatory competitive conditions, NW Natural believes it is reasonable to expect continued application of regulatory accounting for NGD activities. Further, it is reasonable to expect the recovery or refund of NW Natural's regulatory assets and liabilities at December 31 ,2018 through future customer rates. lf it is determined that all or a portion of these regulatory assets or liabilities no longer meet the criteria for continued application of regulatory accounting, then NW Natural would be required to write-off the net unrecoverable balances against earnings in the period such determination is made. The net balance in regulatory asset and liability accounts was a net liability of $245.3 million and a net liability of $217 .7 million as of December 3'l ,2018 and 2017 , respectively. See Note 2 for more detail on regulatory balances. Revenue Recognition Revenues, which are derived primarily from the sale, transportation, and storage of natural gas, are recognized upon the delivery of gas commodity or services rendered to customers. Accrued Unbilled Revenue For a description of the policy regarding accrued unbilled revenue, most of which relates to the NGD business at NW Natural, see Note 2. The following table presents changes in key melrics if the estimated percentage of unbilled volume at December 31 was adjusted up or down by 1o/o: 2018 ln milions Up 1% Down 1olo Unbilled revenue increase (decrease;r') $ 0.8 $ Margin increase ldecrease)(') 0.1 Net income before tax increase (decrease)(') 0.1(1) lncludes impact of regulatory mechanisms including decoupling mechanism and excludes the impact of unbilled revenue from water services. Derivative lnstruments and Hedqing Activities NW Natural's gas acquisition and hedging policies set forth guidelines for using financial derivative instruments to Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 57 of210 (0.8) (0 1) (0 1) 55 Table of Contents support prudent risk management strategies. These policies specifically prohibit the use of derivatives for trading or speculative purposes. Financial derivative contracts are utilized to hedge a portion of natural gas sale requirements. These contracts include swaps, options, and combinations of option contracts. NW Natural primarily uses these derivative financial instruments to manage commodity price variability. A small portion of NW Natural's derivative hedging strategy involves foreign currency exchange contracts. Derivative instruments are recorded on the balance sheet at fair value. lf certain regulatory conditions are met, then the derivative instrument fair value is recorded together with an offsetting entry to a regulatory asset or liability account pursuant to regulatory accounting, and no unrealized gain or loss is recognized in current income or loss. See "Regulatory Accounting" above for additional information. The gain or loss from the fair value of a derivative instrument subject to regulatory deferral is included in the recovery from, or refund to, NGD business customers in future periods. lfa derivative contract is not subject to regulatory deferral, then the accounting treatment for unrealized gains and losses is recorded in accordance with accounting standards for derivatives and hedging which is either in current income or loss or in accumulated other comprehensive income or loss (AOCI or AOCL). Derivative contracts outstanding at December 31,2018,20'17 and 2016 were measured at fair value using models or other market accepted valuation methodologies derived from observable market data. Estimates of fair value may change significantly from period-to-period depending on market conditions and prices. These changes may have an impact on results of operations, but the impact would largely be mitigated due to the majority of derivative activities being subject to regulatory deferral treatment. For more information on derivative activily and associated regulatory treatment, see Note 2 and Note 15. The following table summarizes the amount of losses realized from commodity price transactions for the last three years: ln millions 2018 2017 2016 NGD business net loss on: union and union employees hired or re-hired after December 31, 2006 and 2009, respectively, and employees of certain NW Holdings subsidiaries are provided an enhanced Retirement K Savings Plan benefit. The postretirement Welfare Benefit Plan for non-union employees was also closed to new participants several years ago. Net periodic pension and postretirement benefit costs (retirement benefit costs) and projected benefit obligations (benefit obligations) are determined using a number of key assumptions including discount rates, rate of compensation increases, retirement ages, mortality rates and an expected long{erm return on plan assets. See Note 9. Accounting standards also require balance sheet recognition of unamortized actuarial gains and losses and prior service costs in AOCI or AOCL, net of tax. However, the retirement benefit costs related to qualified defined benefit pension and postretirement benefit plans are generally recovered in rates charged to NGD customers, which are set based on accounting standards for pensions and postretirement benefit expenses. As such, NW Natural received approval from the OPUC to recognize the unamortized actuarial gains and losses and prior service costs as a regulatory asset or regulatory liability based on expected rate recovery, rather than including it as AOCI or AOCL under common equity. See"Regu|atory Accounting" above and Note 2, "/ndustry Regulation". ln 2011, NW Natural received regulatory approval from the OPUC and began deferring a portion of pension expense above or below the amount set in rates to a regulatory balancing account on the balance sheet. On October 26, 2018, the OPUC issued an order to freeze NW Natural's pension balancing account as of October 31,2018. The order directed NW Natural and the other parties to the rate case to engage in further regulatory proceedings extending the general rate case docket to resolve open issues with respect to the recovery of the pension balancing account. On February 4, 201 I, NW Natural and the other parties to the rate case filed a joint stipulation with the OPUC outlining a resolution to the issue. See "Regulatory Matters-Regulatory Proceeding Updates-Oregon General Rate Case"for more information. At December 31 , 2018, the cumulative amount deferred for future pension cost recovery was $74.2 million, including accrued interest. The regulatory balancing account includes the recognition of accrued interest on the account balance at NW Natural's authorized rate of return, with the equity portion of this interesl deferred until amounts are collected in rates. A number of factors, as discussed above, are considered in developing pension and postretirement benefit assumptions. For the December 3't, 2018 measurement date, NW Natural reviewed and updated:. the weighted-average discount rate assumptions for pensions increased lrom 3.52"/o lor 201 7 lo 4.20o/o for 20 1 8, and our weighted- average discount rate assumptions for other postretirement benefits increased lrom3.44o/olor2017 1o4.13o/o for20'18. The new rate assumptions were determined for each plan based on a matching of benchmark interest rates to the estimated cash flows, which reflect the timing and amount of future benefit payments. Benchmark interest rates are Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 58 of 210 Commodity Swaps $ 7.4 $ 7.8 $ 26.9 Realized losses from commodity hedges shown above were recorded as increases to cosl of gas and were, or will be, included in annual PGA rates. Pensions and Postretirement Benefits NW Natural maintains a qualified non-contributory defined benefit pension plan, non-qualified supplemental pension plans for eligible executive officers and certain key employees, and other postretirement employee benefit plans covering certain non-union employees. NW Natural also has a qualified defined contribution plan (Retirement K Savings Plan) for all eligible employees. Only the qualified defined benefit pension plan and Retirement K Savings Plan have plan assets, which are held in qualified trusts to fund the respective retirement benefits. The qualified defined benefit retirement plan for union and non- union employees was closed to new participants several years ago. Non- 56 Table of Contents drawn from the FTSE Above Median Curve, which consists of high quality bonds rated AA- or higher by S&P or Aa3 or higher by Moody's; the expected annual rate of future compensation increases, which was updated to a range of 3.25o/o to 3.5% at December 31 , 2018; the expected long{erm return on qualified defined benefit plan assets, which remained unchanged at a rate of 7 .50o/o; the mortality rate assumptions were updated from RP-2006 mortality tables for employees and healthy annuitants with a fully generational projection using scale MP-2017 to RP-2014 mortality tables using scale MP-2018, which contributed to the decrease of our projected benefit obligation; and other key assumptions, which were based on actual plan experience and actuarial recommendations. At December 31, 2018, the net pension liability (benefit obligations less market value of plan assets) for NW Natural's qualified defined benefit plan increased $0.7 million compared lo 2017. The increase in the net pension liability is primarily due to the $30.1 million decrease in plan assets, partially offset by a $29.5 million decrease in the pension benefit obligation. The liability for non-qualified plans decreased $1.3 million, and the liability for other postretirement benefits decreased $0.8 million in 2018. The expected long{erm rate of return on plan assets is determined by averaging the expected earnings for the target asset portfolio. ln developing expected return, historical actual performance and long-term return projections are analyzed, which gives consideration to the current asset mix and target asset allocation. NW Natural believes its pension assumptions are appropriate based on plan design and an assessment of market conditions. The following shows the sensitivity of retirement benefit costs and benefit obligations to changes in certain actuarial assumptions: lmpacl on Retirement lmpact on 2018 Benefit Change in Retirement Obligations at Dollag in miilions Assumption Benefit Costs Dec. 31, 2018 Discount rate: Qualifled defi ned benefit plans Non-qualifled plans Other postretirement benefits Expected long-term retum on plan assets: Oualified defined benefit plans (0.25\o/o operational costs of running a pension plan. Prior to MAP-21, interest rates based on a 24-month average yield of investment grade corporate bonds (also referred to as "segment rate") were used to calculate minimum contribution requirements. MAP-21 established a new minimum and maximum corridor for segment rates based on a 2s-year average of bond yields, which resulted in lower minimum contributions requirements than those under previous regulations. ln August 2014, HATFA was signed and extended funding relief for an additional five years. lncome Taxes Valuation Allowances Deferred tax assets are recognized to the extent that these assets are believed to be more likely than not to be realized. ln making such a determination, available positive and negative evidence is considered, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. NW Holdings and NW Natural have determined that all recorded deferred tax assets are more likely than not to be realized as of December 31,2018. See Note '10. Uncertain Tax Benefits The calculation of tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in the jurisdictions in which we operate. A tax benefit from a material uncertain tax position will only be recognized when it is more likely than not that the position, or some portion thereof, will be sustained upon examination, including resolution of any related appeals or litigation processes, on the basis of the technical merits. NW Holdings and NW Natural participate in the Compliance Assurance Process (CAP) with the lnternal Revenue Service (lRS). Under the CAP program companies work with the IRS to identify and resolve material tax matters before the federal income tax return is filed each year. No reserves for uncertain tax benefits were recorded during 2018, 2017,or2016. See Note 10. Tax Leoislation When significant proposed or enacted changes in income tax rules occur we consider whether there may be a material impact to our financial position, results of operations, cash flows, or whether the changes could materially affect existing assumptions used in making estimates of tax related balances. On December 22, 2017 , H.R.1 - An Act to provide for reconciliation pursuant to titles ll and V of the concurrent resolution on the budget for fiscal year 201 8, also known as the Tax Cuts and Jobs Act (TCJA), was enacted. The TCJA lowers the U.S. federal corporate income tax rate to 21o/o from the existing maximum rate of 35%, effective for our tax year beginning January 1,2018. The TCJA includes specific provisions related to regulated public utilities that generally provide for the continued deductibility of interest expense and the elimination of bonus depreciation. Certain rate normalization requirements for accelerated cost recovery benefits related to regulated plant balances also continue. See Note 10 for more information on how we are impacted by the TCJA. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 59 of 210 Q 1.s $ 0.1 13.4 0.8 0.8 N/A (o.2s)%o 0.7 ln July 2012, President Obama signed MAP-21 into law. This legislation changed several provisions affecting pension plans, including temporary funding relief and Pension Benefit Guaranty Corporation (PBGC) premium increases, which reduces the level of minimum required contributions in the near-term but generally increases contributions in the long-run as well as increasing the 57 Table of Contents The reduced U.S. corporate income tax rate had a material impact on our financial statements in 2O'17. As a result of the reduction of the U.S. corporate income tax ralelo2lo/o, U.S. GAAP requires deferred tax assets and liabilities be revalued as of the date of enactment, with resulting tax effects accounted for in the reporting period of enactment. We recorded a nel revaluation of deferred tax asset and liability balances of $196.4 million as of December 3'l ,2017 , utilizing the reduced federal rale ol21o/o expected to apply when these temporary differences are realized or settled, based upon balances in existence at the date of enactment. This revaluation had no impact on our 2017 cash flows. With respect to other tax legislation, the final tangible property regulations applicable to all taxpayers were issued on September 13, 2013 and were generally effective for taxable years beginning on or after January 1,2014.ln addition, procedural guidance related to the regulations was issued under which taxpayers may make accounting method changes to comply with the regulations. We have evaluated the regulations and do not anticipate any material impact. However, unit-of- property guidance applicable to natural gas distribution networks has not yet been issued and is expected in the near future. We will further evaluate the effect of these regulations after this guidance is issued, but believe the current method is materially consistent with the new regulations and do not expect this additional guidance to have a material effect on our financial statements. Regulatorv Matters Regulatory tax assets and liabilities are recorded to the extent it is probable they will be recoverable from, or refunded to, customers in the future. At December 31, 2018 and 2017, NW Natural had net regulatory income tax assets of $21.4 million and $22.2 million, respectively, representing future rate recovery of deferred tax liabilities resulting from differences in NGD plant financial statement and tax bases and NGD plant removal costs. These regulatory assets are currently being recovered through customer rates. ln 2017,Ihe regulatory asset balance, and its associated defened tax liability, were both reduced by $17.4 million as a result of the TCJA revaluation to reflect the lower corporate income tax rate. At December 31 , 2018 and 20'17 , regulatory income tax assets of $2.3 million and $0.9 million, respectively, were recorded by NWNatural, representing probablefuture rate recovery ofdeferred tax liabilities resulting from the equity portion of AFUDC. ln 201 7, the regulatory asset balance, and its associated deferred tax liability, were both reduced by $0.8 million as a result of the TCJA revaluation to reflect the lower corporate income tax rate. On December 29,2017, NW Natural filed applications with the OPUC and WUTC seeking authorization to defer the overall net benefits of NGD resulting from the TCJA. On the same day, Staff of the OPUC filed an application seeking deferral of changes in NW Natural's federal tax obligations resulting from the TCJA. On January 8, 2018, the WUTC issued a statement acknowledging receipt of NW Natural's application and indicating their intention to incorporate the impact into future rate case proceedings. At December 31 , 2018 and 20'17 , regulatory liability balances, representing the estimated net benefit to NGD customers resulting from the change in deferred taxes as a result of the TCJA, of $217.1 million and $213.3 million, respectively, were recorded by NW Natural. These balances include a gross up for income taxes of $57.5 and $56.5 million, respectively. The TCJA includes specific guidance for determining the shortest time period over which the portion of this regulatory liability resulting from accelerated cost recovery of NGD plant may accrue to the benefit of customers to avoid incurring federal normalization penalties. However, it is anticipated that until such time that customers receive the direct benefit of this regulatory liability, the balance, net of the additional gross up for income taxes, will continue to provide an indirect benefit to customers by reducing the NGD rate base which determines customer rates for service. lt is not possible at this time to determine when the final resolution of these regulatory proceedings will occur, and as result, this regulatory liability is classified as non-current. On February 4,2019, NW Natural and the parties to the 20't 8 Oregon rate case filed a joint stipulation addressing the relurn of net tax benefits to cuslomers. See "Regulatory Matters-Regulatory Proceeding Updates-Ore gon Gene ral Rale Case" for more information. NGD rates in effecl for Oregon through October 3'l , 2018 and for Washington through December 31, 2018 included an allowance to provide for the recovery of the anticipated provision for income laxes incurred as a result of providing regulated services. The provision for income taxes during these periods included an allowance for federal income taxes determined by utilizing the pre-TCJA federal corporate income tax rate of 35 percent. NW Natural recorded an additional regulatory liability representing the deferral of NGD's net benefit from a lower provision for income taxes due to the newly enacted 21 percent federal corporate income tax rate, including a gross up for income taxes. As of December 31, 2018, a regulatory liability of $8.2 million, including accrued interest, was recorded to reflect this revenue deferral. Environmental Contingencies Environmental liabilities are accounted for in accordance with accounting standards under the loss contingency guidance when it is probable that a liability has been incurred and the amount of the loss is reasonably estimable. Amounts recorded for environmental contingencies take numerous factors into consideration, including, among other variables, changes in enacted laws, regulatory orders, estimated remediation costs, interest rates, insurance proceeds, participation by other parties, timing of payments, and the input of legal counsel and thlrd-party experts. Accordingly, changes in any of these variables or other factual circumstances could have a material impact on the amounts recorded for our environmental liabilities. For a complete discussion of environmental accounting policies refer to Note 2. Fot a discussion of current environmental sites and liabilities refer to Note 17. ln addition, for information regarding the regulatory treatment of these costs and NW Natural's regulatory recovery mechanism, see "Results of Operations- Regulatory Matters-Rate Mechanisms-Environmental Cosls" above. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 60 of 210 58 Table of Contents Impairment of Long-Lived Assets and Goodwill Long-lived assets We review the carrying value of longJived assets whenever events or changes in circumstances indicate the carrying amount of the assets might not be recoverable. Factors that would necessitate an impairment assessment of long-lived assets include a significant adverse change in the extent or manner in which the asset is used, a significant adverse change in legal factors or business climate that could affect the value of the asset, or a significant decline in the observable market value or expected future cash flows ofthe asset, among others. When such factors are present, we assess the recoverability by determining whether the carrying value of the asset will be recovered through expected future cash flows. An asset is determined to be impaired when the carrying value of the asset exceeds the expected undiscounted future cash flows from the use and eventual disposition of the asset. lf an impairment is indicated, we record an impairment loss for the difference between the carrying value and the fair value of the longJived assets. Fair value is estimated using appropriate valuation methodologies, which may include an estimate of discounted cash flows. ln the fourth quarter of 2017, we recognized a non-cash pretax impairment of long-lived assets at the Gill Ranch Facility of $192.5 million. We determined circumstances existed that indicated the carrying value ofthe assets may not be recoverable. Those circumstances included the completion of a comprehensive strategic review process that evaluated various alternatives including a potential sale, as well as contracting for available storage at lower than anticipated values for the coming storage year. Given these considerations, management was required to re-evaluate the estimated cash flows from our interests in the Gill Ranch Facility, and determined that those estimated cash flows were no longer sufficient to cover the carrying value of the assets. We used the income approach to estimate fair value, using the estimated future net cash flows. We also compared the resulls of the income approach to our own recent sale experience and recent market comparable transactions in order to estimate fair value. Many factors and assumptions impact the net cash flows used. The most significant and uncertain estimates included ourforecast of gas storage pricing, our ability to successfully identify and contract with higher-value customers in and/or near the northern California market that Gill Ranch serves, and exploring the possibility of providing energy storage services such as compressed gas energy storage (CGES). After completing the strategic evaluation, which included a potential sale in the fourth quarter of 2017, we lowered our views of a near-term market recovery and decreased the likelihood associated with contracting with higher-value customers. These changes were the most significant estimates that caused our cash flow projections to decrease to a point where they were no longer sufficient to cover the carrying value of the asset. On June 20,2018, NWN Gas Storage, NW Holdings' wholly-owned subsidiary, entered into a Purchase and Sale Agreement that provides for the sale by NWN Gas Storage of all of the membership interests in Gill Ranch. As a result of our strategic shift away from California gas storage operations and the significance of Gill Ranch's financial results in 2017 ,we concluded that the pending sale of Gill Ranch qualifies as assets and liabilities held for sale and discontinued operations. As such, the assets and liabilities associated with Gill Ranch have been classified as discontinued operations assets and discontinued operations liabilities, respectively, and, the results of Gill Ranch are presented separately from the results of continuing operations, net of tax, as discontinued operations for the consolidated results of NW Holdings in all periods presented. The expenses included in the results of discontinued operations within the consolidated results of NW Holdings are the direct operating expenses incurred by Gill Ranch that may be reasonably segregated from the costs of our continuing operations. See "Results of Operations - Pending Sale of Gill Ranch Sforage" above, Note 4, and Note 18 for additional information. Goodwill ln a business combination, goodwill is initially measured as any excess of the acquisition-date fair value of the consideration transferred over the acquisition-date fair value of the net identifiable assets acquired. The carrying value of goodwill is reviewed annually during the fourth quarter using balances as of October 1, or whenever events or changes in circumstance indicate that such carrying values may not be recoverable. NW Holdings and NW Natural early-adopted ASU 2017-04, "Simplifying the Test for Goodwill lmpairment" in the third quarter of 2018. The ASU removes Step 2 from the goodwill impairment test and under the amended guidance an entity should perform its annual goodwill impairmenl test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount in which the carrying amounts exceed the fair value of the reporting unit. ln accordance with the updated guidance per ASU 2017-04, NW Holdings' and NW Natural's policy for goodwill assessments begins with a qualitative analysis in which events and circumstances are evaluated, including macroeconomic conditions, industry and market conditions, regulatory environments, and the overall financial performance of the reporting unit. lf the qualitative assessment indicates that the carrying value may be at risk of recoverability, a quantitative evaluation is performed to measure the carrying value against the fair value of the reporting unit. This evaluation may involve the assessment of future cash flows and other subjective factors for which uncertainty exists and could impact the estimation of future cash flows. These factors include, but are not limited to, the amount and timing of future cash flows, future growth rates, and the discount rate. Unforeseen events and changes in circumstances or market conditions could adversely affect these estimates, which could result in an impairment charge. A qualitative assessment was performed during the fourth quarter of 2018 which indicated a quantitative assessment was not required; thus, no goodwill impairment was recorded. See Note 2 and Note '14 for additional information. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 6'l of 210 59 Table of Contents ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK NW Holdings and NW Natural are exposed to various forms of market risk including commodity supply risk, commodity price risk, interest rate risk, foreign currency risk, credit risk and weather risk. The following describes NW Holdings'and NW Natural's exposure to these risks, as applicable. Commodity Supplv Risk NW Natural enters into spot, short-term, and long-term natural gas supply contracts, along with associated pipeline transporlation contracts, to manage commodity supply risk. Historically, NW Natural has arranged for physical delivery of an adequate supply of gas, including gas in Mist storage and off-system storage facilities, to meet expecled requirements of core NGD customers. NW Natural's long-term gas supply contracts are primarily index-based and subject to monthly re-pricing, a strategy that is intended to substantially mitigate credit exposure to physical gas counterparties. Absolute notional amounts under physical gas contracts related to open positions on derivative instruments were 472.3 million therms and 520.3 million therms as of December 31 , 2018 and 2017, respectively. Commodity Price Risk Natural gas commodity prices are subject to market fluctuations due to unpredictable factors including weather, pipeline transportation congestion, drilling technologies, market speculation, and other factors that affect supply and demand. Commodity price risk is managed with financial swaps and physical gas reserves from a long{erm investment in working interests in gas leases operated by Jonah Energy. These financial hedge contracts and gas reserves volumes are generally included in NW Natural's annual PGA filing for recovery, subject to a regulatory prudence review. Notional amounts under financial derivative contracts were $77.7 million and $1 08.1 million as of December 31 , 2018 and 2017, respectively. The fair value of financial swaps as of December 31, 2018 was an unrealized loss of $7.8 million with future cash outflows of $2.8 million in 2019, $2.5 million in2020, and $2.5 million in 2021. lnterest Rate Risk NW Holdings and NW Natural are exposed to interest rate risk primarily associated with new debt financing needed to fund capital requirements, including future contractual obligations and maturities of long{erm and short{erm debt. lnterest rate risk is primarily managed through the issuance of fixed-rate debt with varying maturities. NW Holdings and NW Natural may also enter into financial derivative instruments, including interest rate swaps, options and other hedging instruments, to manage and mitigate interest rate exposure. NW Holdings and NW Natural did not have any interest rate swaps outstanding as of December 31, 201 I or 2017 . Foreign Currencv Risk The costs of certain pipeline and off-system storage services purchased from Canadian suppliers are subject to changes in the value of the Canadian currency in relation to the U.S. currency. Foreign currency forward contracts are used to hedge against fluctuations in exchange rates for NW Natural's commodity-related demand and reservalion charges paid in Canadian dollars. Notional amounts under foreign currency forward contracts were $6.9 million and $7.7 million as of December 31, 2018 and 2017 , respectively. lf all of the foreign currency fonivard contracts had been settled on December 31 , 2018, a loss of 90.3 million would have been realized. See Note 15. Credit Risk Credit Exposure to Natural Gas Suopliers Certain gas suppliers have either relatively low credit ratings or are not rated by major credit rating agencies. To manage this supply risk, NW Natural purchases gas from a number of different suppliers at liquid exchange points. NW Natural evaluates and monitors suppliers' creditworthiness and maintains the ability to require additional financial assurances, including deposits, letters of credit, or surety bonds, in case a supplier defaults. ln the event of a supplier's failure to deliver contracted volumes of gas, the NGD business would need to replace those volumes at prevailing market prices, which may be higher or lower than the original lransaction prices. NW Natural expects these cosls would be subject to its PGA sharing mechanism discussed above. Since most of NW Natural's commodity supply contracts are priced at the daily or monthly market index price tied to liquid exchange points, and NW Natural has adequate storage flexibility, NW Natural believes it is unlikely a supplier default would have a material adverse effect on its financial condition or results of operations. Credit Exposure to Financial Derivative Counterparties Based on estimated fair value at December 31, 2018, NW Natural's overall credit exposure relating to commodity contracts is considered immaterial as it reflects amounts owed to financial derivative counterparties (see table below). However, changes in natural gas prices could result in counterparties owing NW Natural money. Therefore, NW Natural's financial derivatives policy requires counterparties to have at least an investment-grade credit rating at the time the derivative instrument is entered into and specific limits on the contract amount and duration based on each counterparty's credit rating. Due to potential changes in market conditions and credit concerns, NW Natural continues to enforce strong credit requirements. NW Natural actively monitors and manages derivative credit exposure and places counterparties on hold for trading purposes or requires cash collateral, letters of credit, or guarantees as circumstances warrant.

Customers in Oregon are allowed to opt out of the weather normalizalion mechanism. As of December 31, 2018, approximalely 8o/o of Oregon customers had opted out. ln addition to the Oregon customers opting out, Washington residential and commercial customers account for approximately 1 1% of our total customer base and are not covered by weather normalization. The combination of Oregon and Washington customers not covered by a weather normalization mechanism is 1 9% of all residential and commercial customers. See "Results of Operations-Regulatory Matters-Rate Mechanisms-WARM" above. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 63 of 210 $ $ $ $ (22.3') ln most cases, NW Natural also mitigates the credit risk of financial derivatives by having master netting arrangements with counterparties which provide for making or receiving net cash settlements. Generally, transactions of the same type in the same currency that have settlement on the same day with a single counterparty are netted and a single payment is delivered or received depending on which party is due funds. Additionally, NW Natural has master contracts in place with each derivative counterparty that include provisions for posting or calling for collateral. Generally, NW Natural can obtain cash or marketable securities as collateral with one day's notice. Various collateral management strategies are used to reduce liquidity risk. The collateral provisions vary by counterparty but are not expected to result in the significant posting of collateral, if any. NW Natural has performed stress tests on the portfolio and concluded the liquidity risk from collateral calls is not material. Derivative credit exposure is primarily with investment grade counterparties rated AAJAa3 or higher. Contracts are diversified across counterparties to reduce credit and liquidity risk. At December 31 ,2018, financial derivative credit risk on a volumetric basis was geographically concentrated 33% in the United States and 67% in Canada, based on counterparlies'location. At December 31, 2017, financial derivative credit risk on a volumetric basis was geographically concentrated 36% in the United States and 64% in Canada with our counterparties. Credit Exposure to lnsurance Companies Credit exposure to insurance companies for loss or damage claims could be material. NW Holdings and NW Natural regularly monitor the financial condition of insurance companies who provide general liability insurance policy coverage to NW Holdings, NW Natural, their predecessors, and their subsidiaries. Weather Risk NW Natural has a weather normalization mechanism in Oregon; however, it is exposed to weather risk primarily from NGD business operations. A large percentage of NGD margin is volume driven, and current rates are based on an assumption of average weather. NW Natural's weather normalization mechanism in Oregon is for residential and $(7.8) $ 61 Table of Contents ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA TABLE OF CONTENTS 2. 3. 1.

Palfreyman, Falls Water Co., lnc. Page 79 ot21076 36,023 17,157) Table of Contents NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. ORGANIZATION AND PRINCIPLES OF CONSOLIDATION On October 1,20'18, we completed a reorganization into a holding company structure. ln this reorganization, shareholders of NW Natural (the predecessor publicly held parent company) became shareholders of NW Holdings on a one-for-one basis; maintaining the same number of shares and ownership percentage as held in NW Natural immediately prior to the reorganization. NW Natural became a wholly-owned subsidiary of NW Holdings. Additionally, cerlain subsidiaries of NW Natural were transferred to NW Holdings. Thls reorganization was accounted for as a transaction among entities under common control. As required under accounting guidance, these subsidiaries are presented in this report as discontinued operations in the consolidated results of NW Natural. See Note 18 for additional information. The accompanying consolidated financial statements represent the respective, consolidated results and financial results of NW Holdings and NW Natural and all respective companies that each registrant directly or indirectly controls, either through majority ownership or otherwise. This is a combined report of NW Holdings and NW Natural which includes separate consolidated financial statements for each registrant. NW Nalural's natural gas distribution activities are reported in the natural gas distribution (NGD) segment, formerly titled and reported as the utility segmenl. The NGD segment is NW Natural's core operating business and serves residential, commercial, and industrial customers in Oregon and southwest Washington. The NGD segment is the only reportable segment for NW Holdings and NW Natural. All other business activities, including certain gas storage activities, water businesses, and other investments and activities are aggregated and reported as other at their respective registrant. ln addition, NW Holdings has reported discontinued operalions results related to the pending sale of Gill Ranch Storage, LLC (Gill Ranch). NW Holdings'direct and indirect wholly-owned subsidiaries include: Northwest Natural Gas Company (NW Natural);. Northwest Energy Corporation (Energy Corp);. NWN Gas Reserves LLC (NWN Gas Reserves); NW Natural Energy, LLC (NWN Energy); " NW Natural Gas Storage, LLC (NWN Gas Storage);. Gill Ranch Storage, LLC (Gill Ranch), which is presented as a discontinued operation; NNG Financial Corporation (NNG Financial);. KB Pipeline Company (KB); NW Natural Water Company, LLC (NWN Water); " Falls Water Co., lnc. (Falls Water);. Salmon Valley Water Company; Cascadia Water, LLC (Cascadia); NW Natural Water of Oregon, LLC (NWN Water of Oregon); NW Natural Water of Washington, LLC (NWN Water of Washington); and NW Natural Water of ldaho, LLC (NWN Water of ldaho); and. Gem State Water Company, LLC (Gem State) lnvestments in corporate joint ventures and partnerships that NW Holdings does not directly or indirectly control, and for which it is not the primary beneficiary, include NWN Financial's investment in Kelso-Beaver Pipeline and NWN Energy's investment in Trail West Holdings, LLC (TWH), which is accounted for under the equity method. NW Holdings and its direct and indirect subsidiaries are collectively referred to herein as NW Holdings, and NW Natural and its direct and indirect subsidiaries are collectively referred to herein as NW Natural. The consolidated financial statements of NW Holdings and NW Natural are presented after elimination of all intercompany balances and transactions. During the second quarter of 2018, we moved forward with our long{erm strategic plans, which include a shift away from the California gas storage business. ln June 2018, NWN Gas Storage, a wholly-owned subsidiary of NW Natural at the time and now a wholly-owned subsidiary of NW Holdings, entered into a Purchase and Sale Agreement that provides for the sale of all of the membership interests in its wholly- owned subsidiary, Gill Ranch, subject to various regulatory approvals and closing conditions. We have concluded that the pending sale of Gill Ranch qualifies as assets and liabilities held for sale and discontinued operations. As such, the results of Gill Ranch have been presented as a discontinued operation for NW Holdings for all periods presented and for NW Natural up until the holding company reorganization was effective on October 1 , 2018 on the consolidated statements of comprehensive income and cash flows, and the assets and liabilities associated with Gill Ranch have been classified as discontinued operations assets and liabilities on the NW Holdings consolidated balance sheet. See Note 18 for additional information. Additionally, we reevaluated reportable segments and concluded that the remaining gas storage activities no longer meet the requirements to be separately reported as a segment. lnterstate Storage Services is now reported in Other under NW Natural and all prior periods reflect this change. See Note 4, which provides segment information. Notes to the consolidated financial statements reflect the activity of continuing operations for both NW Holdings and NW Natural for all periods presented, unless otherwise noted. Note 4 and Note 18 provide information regarding reportable segments and discontinued operations, respectively. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 81 ot210 77 Table of Contents All prior period amounts have been retrospectively adjusted to reflect the change in reportable segments and the designation of Gill Ranch as a discontinued operation for NW Holdings, and the designation of subsidiaries previously owned by NW Natural that are now owned by NW Holdings as discontinued operations for NW Natural. These 2. SIGNIFICANT ACCOUNTING POLICIES reclassifications and the reorganization activities described above had no effect on the prior year's consolidated results of operations, financial condition, or cash flows. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect reported amounts in the consolidated financial statements and accompanying notes. Actual amounts could differ from those estimates, and changes would most likely be reported in future periods. Management believes the estimates and assumptions used are reasonable. lndustry Regulation NW Holdings' principal business is to operate as a holding company for NW Natural, NWN Water and its other subsidiaries. NW Natural's principal business is the distribution of natural gas, which is regulated by the OPUC and WUTC. NW Natural also has natural gas storage services, which are regulated by the FERC, and to a certain extent by the OPUC and WUTC. Additionally, certain NW Holdings' subsidiaries own water businesses, which are regulated by the OPUC, WUTC, or IPUC. Accounting records and practices of the regulated businesses conform to the requirements and uniform system of accounts prescribed by these regulatory authorities in accordance wilh U.S. GAAP. The businesses in which customer rates are regulated by the OPUC, WUTC, IPUC, and FERC have approved cost-based rates which are intended to allow such businesses to earn a reasonable return on invested capital. ln applying regulatory accounting principles, we capitalize or defer certain costs and revenues as regulatory assets and liabilities pursuant to orders of the OPUC, WUTC, or IPUC, which provide for the recovery of revenues or expenses from, or refunds to, utility customers in future periods, including a return or a carrying charge in certain cases. At December 31, NW Natural deferred the following amounts as regulatory assets and liabilities: Regulatory Assets ln thousands 2018 2017 Cunent: Unrealized loss on derivatives(') Gas costs Environmental costs(') Decoupling(t) lncome taxes Othe/o) Total cunent Non-current: Unrealized loss on derivatives(') Pension balancing(s) lncome taxes Pension and other postretirement benefit liabilities Environmental costse) Gas costs Demuplingo) Other'o) Total non-current ln thousands 18,712 154 6,1 98 11,227 2,218 7,272 $ 41,930 $ 45,781 $12,381 $ 2,873 5,601 9,1 40 2,218 9,717 $3,025 $ 74,173 19,'185 4,649 60,383 19,991 179,824 72,128 84 3,970 15,579 174,993 76,149 9,978 2,545 11,738 $ 371,786 $ 356,608 Regulatory Liabilities 2018 2017 Current: Gas costs Unrealized gain on derivatives(') DecouplingG) other(t) Total cunent Non-current: Gas costs Unrealized gain on derivatives(1) Decoupling€) lncome taxes(u) Accrued asset removal coslso Other'') Total non-current c$ 725 225,408 380,464 4,411 4,630 '1,306 957 213,306 360,929 4,965 $ 611,560 $ 586,093(') Unrealized gains or losses on derivatives are non-cash items and, therefore, do not eam a rate of return or a carrying charge.

See Note 1 0.o Estimated costs of removal on certain regulated properties are collected through rates. See'Accounting Policies-Plant, Property, and Accrued Asset Removal Costs" below. The amortization period for NW Natural's regulatory assets and liabilities ranges from less than one year to an indeterminable period. Regulatory deferrals for gas costs payable are generally amortized over 12 months beginning each November 1 following the gas contract year during which the deferred gas costs are recorded. Similarly, most other regulatory defened accounts are amortized over 12 months. However, certain regulatory account balances, such as income taxes, environmental costs, pension liabilities, and accrued asset removal cosls, are large and tend to be amortized over longer periods once NW Natural has agreed upon an amortization period with the respective regulatory agency. We believe all costs incurred and deferred at December 31 , 2018 are prudent. All regulatory assets and liability are reviewed annually for recoverability, or more often if circumstances warrant. lf it is determined that all or a portion of these regulatory assets or liabilities no longer meet the criteria for continued application of regulatory accounting, then NW Natural would be required to write-off the net unrecoverable balances in the period such determination is made. Environmental Requlatory Accounting See Note 17 for information about the SRRM and OPUC orders regarding implementation. New Accounting Standards NW Holdings and NW Natural consider the applicability and impact of all accounting standards updates (ASUs) issued by the Financial Accounting Standards Board (FASB). ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on the consolidated financial position or results of operations. Recentlv Adopted Accountinq Pronouncements STOCK COMPENSATION. On May 10,2017, the FASB issued ASU 2017- 09, "Stock Compensation - Scope of Modification Accounting." The purpose of the amendment ls to provide clarity, reduce diversity in practice, and reduce the cost and complexity when applying the guidance in Topic 718, related to a change to the terms or conditions of a share- based payment award. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. The amendments in this update were effective beginning January 1 ,2018, and will be applied prospectively to any award modified on or after the adoption date. The adoption did not have a material impact to the financial statements or disclosures of NW Holdings or NW Natural. RETIREMENT BENEFITS. On March 10,2017, the FASB issued ASU 2017- 07, "lmproving the Presentation of Net Periodic Pension Cost and Net Periodic Post Retirement Benefit Cost." The ASU requires entities to disaggregate current service cost from the other components of net periodic benefit cost and present it with other current compensation costs for related employees in the income statement. Additionally, the other components of net periodic benefit costs are to be presented elsewhere in the income statement and outside of income from operations if that subtotal is presented. Only the service cost component of the net periodic benefit cost is eligible for capitalization. The amendments in this update were effective beginning January 1,2018. Upon adoption, the ASU required that changes to the income statement presentation of net periodic benefit cost be applied retrospectively, while changes to amounts capitalized must be applied prospectively. As such, the interest cost, expected return on assets, amortization of prior service costs, and other costs have been reclassified from operations and maintenance expense to other income (expense), net on the consolidated statements of comprehensive income for the years ended December 31 , 2017 and 2016. We did not elect the practical expedient which would have allowed for the reclassification of amounts disclosed previously in the pension and other postretirement benefits footnote disclosure as the basis for applying retrospective presentation. As mentioned above, on a prospective basis, the other components of net periodic benefit cost will not be eligible for capitalization. The retrospective presentation requirement related to the other components of net periodic benefit cost affected the operations and maintenance expense and other income (expense), net lines on the NW Natural consolidated statements of comprehensive income. For the years ended December 31 , 2017 and 2016, $5.6 million and $6.6 million of expense was reclassified from operations and maintenance expense and included in other income (expense), net, respectively. GOODWILL. On January 26,2017, the FASB issued ASU 2017-04, "Simplifying the Test for Goodwill lmpairment." The ASU removes Step 2 from the goodwill impairment test and under the amended guidance an entity should perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount in which the carrying Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 84 of210 79 Table of Contents amounts exceed the fair value of the reporting unit. The amendments in this standard are effective beginning January 1,2020 and early adoption is permitted for interim or annual goodwill impairment tests performed after January 1 ,2017 - ASU 2017-04 was early adopted in the third quarter ended September 30, 2018. The adoption of this ASU did not materially affect the financial statements or disclosures of NW Holdings or NW Natural and is currently not applicable to NW Natural. STATEMENT OF CASH FLOWS. On August 26,2016, the FASB issued ASU 2016-1 5, "Classification of Certain Cash Receipts and Cash Payments." The ASU adds guidance pertaining to the classification of certain cash receipts and payments on lhe statement of cash flows. The purpose of the amendment is to clarify issues that have been creating diversity in practice. The amendments in this standard were effective beginning January 1,2018, and the adoption did not have a material impact to financial statements or disclosures as our historical practices and presentation were consistent with the directives of this ASU for NW Holdings and NW Natural. FINANCIAL INSTRUMENTS. On January 5, 2016, the FASB issued ASU 2016-01, "Financial lnstruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities." The ASU enhances the reporting model for financial instruments, which includes amendments to address aspects of recognition, measurement, presentation, and disclosure. The new standard was effective beginning January 1,20'18, and the adoption did not materially impact the financial statements or disclosures of NW Holdings or NW Natural. REVENUE RECOGNITION. On May 28,2014, the FASB issued ASU 2014- 09 "Revenue From Contracts with Customers." The underlying principle of the guidance requires entities to recognize revenue depicting the transfer of goods or services to customers at amounts the entity is expected to be entitled to in exchange for those goods or services. The ASU also prescribes a five-step approach to revenue recognition: (1) identify the contract(s) with the customer; (2) identify the separate performance obligations in the contract(s); (3) determine the transaction price; (4) allocate the transaclion price to separate performance obligations; and (5) recognize revenue when, or as, each performance obligation is satisfied. The guidance also requires additional disclosures, both qualitative and quantitative, regarding the nature, amount, timing and uncertainty of revenue and cash flows. The new accounting standard and all related amendments were effective beginning January 1 , 201 8. The accounting standard was applied to all contracts using the modified retrospective method. The new standard is primarily reflected in the consolidated statements of comprehensive income and Note 6. The implementation of the new revenue standard did not result in changes to how NW Holdings and NW Natural currently recognize revenue, and therefore, no cumulative effect or adjustment to the opening balances of retained earnings was required. The implementation did result in changes to the disclosures and presentation of revenues and expenses. The comparative information for prior years has not been restated. There is no material impact to the financial results of NW Holdings or NW Natural and no significant changes to our control environment due to the adoption of the new revenue standard on an ongoing basis. As previously discussed, the adoption of the new revenue standard did not impact the consolidated balance sheets or statements of cash flows but did result in changes to the presentation ofthe consolidated statements of comprehensive income for NW Holdings and NW Natural. Had the adoption of the new revenue standard not occurred, operating revenues forthe year ended December 31, 2018 would have been $676.0 million for NW Holdings, compared to the reported amount of $706.1 million underthe new revenue standard. Similarly, absent the impact ofthe new revenue standard, operating expenses would have been $543.9 million for NW Holdings, compared to the reported amount of $574.0 million under the new revenue standard for the year ended December 31 , 201 8. The effect of the change was an increase in both operating revenues and operating expenses of $30.1 million at NW Holdings and NW Natural for the year ended December 31, 201 8; due to the change in presentation of revenue taxes. As part of the adoption of the new revenue standard, we evaluated the presentation of revenue taxes under the new guidance and across our peer group and concluded that the gross presentation of revenue taxes provides the greatest level of consistency and transparency. Prior to the adoption of the new revenue standard, a portion of revenue taxes was presented net in operating revenues and a portion was recorded directly on the balance sheet. During year ended December 31 , 2018, $30.1 million in revenue taxes for NW Holdings and NW Natural was recognized in operating revenues and operating expenses. ln comparison, for the years ended December 31 ,2017 and 2016, $32.2 million and $28.3 million was recognized in revenue taxes for NW Holdings and NW Natural, of which $19. 1 million and $17.1 million were recorded in operating revenues and $13. 1 million and $1 1 .2 million were recorded on the consolidated balance sheets, respectively. The change in presentation of revenue taxes had no impact on NGD margin, net income or earnings per share. Recentlv lssued Accounting Pronouncements CLOUD COMPUTING. On August 29, 2018, the FASB issued ASU 2018- 15, "Customer's Accounting for lmplementation Costs lncurred in a Cloud Computing Arrangement That ls a Service Contract." The purpose of the amendment is to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain intemal-use software. The amendments in this update are effective beginning January 1,2020. Early adoption is permitted. The amended guidance can be applied either retrospectively or prospectively to all implementation costs incurred afler the date of adoption. We are currently assessing the effect of this standard on NW Holdings'and NW Natural's financial statements and disclosures. RETIREMENT BENEFITS. On August 28,2018, the FASB issued ASU 2018-'l4, "Changes to the Disclosure Requirements for Defined Benefit Plans." The purpose of the amendment is to modify the disclosure requirements for Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 85 of 210 80 Table of Contents defined benefit pension and other postretirement plans. The amendments in this update are effective for the year ended December 31 ,2020. Early adoption is permitted. The amended presentation and disclosure guidance should be applied retrospectively. We are currently assessing the effect of this standard on NW Holdings' and NW Natural's disclosures. FAIR VALUE MEASUREMENT. On August 28,20'18, the FASB issued ASU 2018-13, "Changes to the Disclosure Requirements for Fair Value Measurement." The purpose of the amendment is to modify the disclosure requirements for fair value measurements. The amendments in this update are effective beginning January 1 , 2020. Early adoption is permitted. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty should be applied prospectively. All other amendments should be applied retrospectively. We are currently assessing the effect of this standard on NW Holdings' and NW Natural's disclosures. ACCUMULATED OTHER COMPREHENSIVE INCOME. On February 14, 2018, the FASB issued ASU 2018-02, "lncome Statement-Reporting Comprehensive lncome: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive lncome." This update was issued in response to concerns from certain stakeholders regarding the current requirements under U.S. GAAP that deferred tax assets and liabilities are adjusted for a change in tax laws or rates, and the effect is to be included in income from continuing operations in the period of the enactment date. This requirement is also applicable to items in accumulated other comprehensive income where the related tax effects were originally recognized in other comprehensive income. The adjustment of deferred laxes due to the new corporate income tax rate enacted through the TCJA on December 22,2017 recognized in income from continuing operations causes the tax effects of items within accumulated other comprehensive income (referred to as stranded tax effects) to not reflect the appropriate tax rate. The amendments in this update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the TCJA and require certain disclosures about stranded tax effects. The amendments in this update are effective beginning January 'l ,2019, and should be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the federal corporate income tax rate in the TCJA is recognized. The reclassification allowed in this update is elective, and we are currently assessing whether we will make the reclassification. This update is not expected to have a material impact on the financial condition of NW Holdings or NW Natural. DERIVATIVES AND HEDGING. On August 28,2017, the FASB issued ASU 2017-12, "Derivatives and Hedging: Targeted lmprovements to Accounting for Hedging Activities." The purpose of the amendment is to more closely align hedge accounting with companies' risk management strategies. The ASU amends the accounting for risk component hedging, the hedged item in fair value hedges of interest rate risk, and amounts excluded from the assessment of hedge effectiveness. The guidance also amends the recognition and presentation of the effect of hedging instruments and includes other simplifications of hedge accounting. The amendments in this update are effective beginning January 1 , 20'19. Early adoption is permitted. The amended presentation and disclosure guidance is required prospectively. We do not anticipate the adoption of this standard to have a material impact on NW Holdings'and NW Natural's financial statements and disclosures. LEASES. On February 25,2016, the FASB issued ASU 2016-02, "Leases," which revises the existing lease accounting guidance. Pursuant to the new standard, lessees will be required to recognize all leases, including operating leases that are greater than 12 months at lease commencement, on the balance sheet and record corresponding right-of-use assets and lease liabilities. Lessor accounting will remain substantially the same under the new standard. Quantitative and qualitative disclosures are also required for users of the financial statements to have a clear understanding of the nature of NW Natural's leasing activities. On July 30, 2018, the FASB approved an optional alternative transition approach that would allow entities to apply the transition requirements on the effective date of the standard. Additionally, on January 25,2018, the FASB issued ASU 2018-01, "Land Easement Practical Expedient for Transition to Topic 842", to address the costs and complexity of applying the transition provisions of the new lease standard to land easements. This ASU provides an optional practical expedient to not evaluate existing or expired land easements that were not previously accounted for as leases under the current lease guidance. The standard and associated ASUs were effective for us beginning January 1 , 2019. We elected the alternative prospective transition approach for adoption of ASC 842 beginning January 1 , 2019. All comparative periods prior to January 1 , 20'19 will retain the financial reporting and disclosure requirements of ASC 840 "Leases" ('ASC 840). We elected the land easement optional practical expedient to not evaluate existing or expired land easements that were not previously accounted for as leases under the current lease guidance. For the existing lease portfolio, we did not elect the optional practical expedient package to retain the legacy lease accounting conclusions upon adoption; rather, we re-assessed our existing contracts under the new leasing standard including whether the contract meets the definition of a lease and lease classification. As a result, we determined that most of our underground gas storage contracts no longer meet the definition of a lease under the new lease standard. Our lease portfolio under the new standard consists primarily of our leased headquarters, which expires in 2020. Upon adoption, NW Holdings expects to record a right-of-use lease asset and an associated lease liability of approximately $7.3 million, of which $7.0 million is expected to be recorded at NW Natural. ln October 2017, NW Natural entered into a 20-year operating lease agreement commencing in 2020 for the new headquarters location in Portland, Oregon. Under the new lease standard, NW Natural is no longer considered the accounting owner ofthe asset during construction. As such, Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 86 o1210 81 Table of Contents we expect to de-recognized the build{o-suit asset and liability balances of $26.0 million as of December 31 ,2018 thatwere recorded underASC 840 within property, plant and equipment and other non-current liabilities in the consolidated balance sheet. Refer to Note 16 for current lease commitments. CREDIT LOSSES. On June 16, 2016, the FASB issued ASU 2016-13, "Measurement of Credit Losses on Financial lnstruments," which applies to financial assets subject to credit losses and measured at amortized cost. The new standard will require financial assets measured at amortized cost to be presented at the net amount expected to be collected and the allowance for credit losses is to be recorded as a valuation account that is deducted from the amortized cost basis. The amendments in this update are effective beginning January '1,2020. Early adoption is permitted for fiscal years beginning after December '15, 2018. We are currently assessing the effect of this standard on the financial statements and disclosures of NW Holdings and NW Natural. Accountinq Policies The accounting policies discussed below apply to both NW Holdings and NW Natural. Plant, Property, and Accrued Asset Removal Costs Plant and property are stated at cost, including capitalized labor, materials, and overhead. ln accordance with regulatory accounting standards, the cost ofacquiring and constructing longJived plant and property generally includes an allowance for funds used during construction (AFUDC) or capitalized interest. AFUDC represents the regulatory financing cost incurred when debt and equity funds are used for construction (see "AFUDC' below). When constructed assets are subject to markelbased rates rather than cost-based rates, the financing costs incurred during construction are included in capitalized interest in accordance with U.S. GAAP, not as regulatory financing costs under AFUDC. ln accordance with long-standing regulatory treatment, our depreciation rates consist ofthree components: one based on the average service life of the asset, a second based on the estimated salvage value of the asset, and a third based on the asset's estimated cost of removal. We collect, through rates, the estimated cost of removal on certain regulated properties through depreciation expense, with a corresponding offset to accumulated depreciation. These removal costs are non-legal obligations as defined by regulatory accounting guidance. Therefore, we have included these costs as non-current regulatory liabilities rather than as accumulated depreciation on our consolidated balance sheets. ln the rate setting process, the liability for removal cosls is treated as a reduction to the net rate base on which the NGD business has the opportunity to earn its allowed rate of return. The costs of NGD plant retired or otherwise disposed of are removed from NGD plant and charged to accumulated depreciation for recovery or refund through future rates. Gains from the sale of regulated assets are generally deferred and refunded to customers. For assets not related to NGD, we record a gain or loss upon the disposal of the property, and the gain or loss is recorded in operating income or loss in the consolidated statements of comprehensive income. The provision for depreciation of NGD property, plant, and equipment is recorded under the group method on a straight-line basis with rates computed in accordance with depreciation studies approved by regulatory authorities. The weighted-average depreciation rate for NGD assets in seryice was approximately 2.8o/o tor 2018,2017, and 2016, reflecting the approximate weighted-average economic life of the property. This includes 2018 weighted-average depreciation rates for the following asset categories'.2.7o/o for transmission and distribution plant, 2.1o/o for gas storage facilities, 4.5% for general plant, and 3.1% for intangible and otherfixed assets. AFUDC. Certain additions to NGD plant include AFUDC, which represents the net cost ofdebt and equity funds used during construction. AFUDC is calculated using actual interest rates for debt and authorized rates for ROE, if applicable. lf short{erm debt balances are less than the total balance of construction work in progress, then a composite AFUDC rate is used to represent interest on all debt funds, shown as a reduction to interest charges, and on ROE funds, shown as other income. While cash is not immediately recognized from recording AFUDC, it is realized in future years through rate recovery resulting from the higher NGD cost of service. Our composite AFUDC rate was 5.2o/o in 2018,5.5o/o in 2017 , and 0.7o/o in 2016. IMPAIRMENT OF LONG-LIVED ASSETS. We review the carrying value of longJived assets whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable. Factors that would necessitate an impairment assessment of longJived assets include a significant adverse change in the extent or manner in which the asset is used, a significant adverse change in legal factors or business climate that could affect the value of the asset, or a significant decline in the observable market value or expected future cash flows ofthe asset, among others. When such factors are present, we assess the recoverability by determining whether the carrying value of the asset will be recovered through expected future cash flows. An asset is determined to be impaired when the carrying value of the asset exceeds the expected undiscounted future cash flows from the use and eventual disposition of the asset. lf an impairment is indicated, we record an impairment loss for the difference between the carrying value and the fair value of the long-lived assets. Fair value is estimated using appropriate valuation methodologies, which may include an estimate of discounted cash flows. ln the fourth quarter of 2017, a non-cash pre-tax impairment of long-lived assets at the Gill Ranch Facility of $192.5 million was recognized. The income approach was used to estimate fair value, using the estimated future net cash flows. We also compared the results of the income approach to our own recent sale experience and recent market comparable transactions in order to estimate fair value. The Gill Ranch Facility was originally included in the gas storage segment, which has since been eliminated, and is now included in discontinued operations. We determined Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 87 of210 82 Table of Contents circumstances existed that indicated the carrying value of the assets may not be recoverable. Those circumstances included the completion of a comprehensive strategic review process that evaluated various alternatives including a potential sale, as well as contracting for available storage at lower than anticipated values for the coming storage year. Given these considerations, management re-evaluated the estimated cash flows from our interests in the Gill Ranch Facility, and determined that those estimated cash flows were no longer sufficient to cover the carrying value of the assets. The results of Gill Ranch have been presented as a discontinued operation for NW Holdings and NW Natural on the consolidated statements of comprehensive income and cash flows, and the assets and liabilities associated with Gill Ranch have been classified as discontinued operations assets and liabilities on the consolidated balance sheets. See Note 18 for additional information. Cash and Equivalents For purposes of reporting cash flows, cash and cash equivalents include cash on hand plus highly liquid investment accounts with original maturity dates of three months or less. At December 3'l , 2018 and 2017 , NW Holdings had outstanding checks of approximately $2.7 million and $4.8 million, respectively, substantially all of which is recorded at NW Natural. These balances are included in accounts payable in the NW Holdings and NW Natural balance sheets. Revenue Recoqnition and Accrued Unbilled Revenue Revenues, derived primarily from the sale and transportation of natural gas, are recognized upon delivery of the gas commodity or service to customers. Revenues include accruals for gas or water delivered but not yet billed to customers based on estimates of deliveries from meter reading dates to month end (accrued unbilled revenue). Accrued unbilled revenue is dependent upon a number of factors that require management's judgment, including total natural gas receipts and deliveries, customer use of natural gas or water by billing cycle, and weather factors. Accrued unbilled revenue is reversed the following month when actual billings occur. NW Holdings' accrued unbilled revenue at December 31 , 2018 and 2017 was $57.8 million and $62.4 million, respectively, substantially all of which is accrued unbilled revenue at NW Natural. Revenues not related to NGD are derived primarily from lnterstate Storage Services, asset management activities at the Mist gas storage facility, and other investments and business activities. At the Mist underground storage facility, revenues are primarily firm service revenues in the form of fixed monthly reservation charges. ln addition, we also have asset management service revenue from an independent energy marketing company that optimizes commodity, storage, and pipeline capacity release transactions. Under this agreement, guaranteed asset management revenue is recognized using a straight- line, pro-rata methodology over the term of each contract. Revenues earned above the guaranteed amount are recognized as they are earned. Revenue Taxes Revenue-based taxes are primarily franchise taxes, which are collected from customers and remitted to taxing authorities. ln 2018, revenue taxes are included in operating expenses in the statements of comprehensive income for NW Holdings and NW Natural. ln 2017 and 2016, revenue taxes are included in operating revenues in the statements of comprehensive income for NW Holdings and NW Natural. All revenue taxes are recorded at NW Natural and were $30.'1 million, $'1 9.1 million, and $17.1 million for 2018,2017, and 2016, respectively. Accounts Receivable and for Uncollectible Accounts Accounts receivable consist primarily of amounts due for natural gas sales and transportation services to NGD customers, plus amounts due for gas storage services. At NW Holdings and NW Natural we establish allowances for uncollectible accounts (allowance) for trade receivables, including accrued unbilled revenue, based on the aging of receivables, collection experience of past due account balances including payment plans, and historical trends of write-offs as a percent of revenues. A specific allowance is established and recorded for large individual customer receivables when amounts are identified as unlikely to be partially or fully recovered. lnactive accounts are written-off against the allowance afier they arc 120 days past due or when deemed uncollectible. Differences between the estimated allowance and actual write-offs will occur based on a number of factors, including changes in economic conditions, customer creditworthiness, and natural gas prices. The allowance for uncollectible accounts is adjusted quarterly, as necessary, based on information currently available. lnventories NGD gas inventories, which consist of natural gas in storage for NGD, are stated at the lower of average cost or net realizable value. The regulatory treatment of these inventories provides for cost recovery in customer rates. NGD gas inventories injected into storage are priced in inventory based on actual purchase costs, and those withdrawn from storage are charged to cost ofgas during the current period they are withdrawn at the weighted-average inventory cost. Gas storage inventories, which primarily represent inventories at the Gill Ranch Facility and are included in Discontinued operations - current assets on the consolidated balance sheets, mainly consist of natural gas received as fuel-in-kind from storage customers. Gas storage inventories are valued at the lower of average cost or net realizable value. Cushion gas is not included in inventory balances, is recorded at original cost, and is classified as a long-term plant asset. Materials and supplies inventories consist of inventories both related to and unrelated to NGD and are stated at the lower of average cost or net realizable value. NW Natural's NGD and gas storage inventories totaled $29.9 million and $36.7 million at December 31 ,2018 and 2017 , respectively. At December 31, 2018 and 2017 , NW Holdings' materials and supplies anventories, which are comprised Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 88 oI 210 83 Table of Contents primarily of NW Natural's materials and supplies, totaled $14.2 million and $10.9 million, respectively. Gas Reserves Gas reserves are payments lo acquire and produce natural gas reseryes. Gas reserves are stated at cost, adjusted for regulatory amortization, with the associated deferred tax benefits recorded as liabilities on the balance sheet. The current portion is calculated based on expected gas deliveries within the next fiscal year. NW Natural recognizes regulatory amortization of this asset on a volumetric basis calculated using the estimated gas reserves and the estimaled therms extracted and sold each month. The amortization of gas reserves is recorded to cost ofgas along with gas production revenues and production costs. See Note 12. Derivatives NW Natural's derivatives are measured at fair value and recognized as either assets or liabilities on the balance sheet. Changes in the fair value of the derivatives are recognized currently in earnings unless specific regulatory or hedge accounting criteria are met. Accounting for derivatives and hedges provides an exception for contracts intended for normal purchases and normal sales for which physical delivery is probable. ln addition, certain derivative contracts are approved by regulatory authorities for recovery or refund through customer rates. Accordingly, the changes in fair value ofthese approved contracts are deferred as regulatory assets or liabilities pursuant to regulatory accounting principles. NW Natural's financial derivatives generally qualify for deferral under regulatory accounting. NW Natural's index-priced physical derivative contracts also qualifo for regulatory deferral accounting treatment. Derivative contracts entered into for NGD requirements after the annual PGA rate has been set and maturing during the PGA year are subject to the PGA incentive sharing mechanism. ln Oregon, NW Natural participates in a PGA sharing mechanism under which it is required to select either an 80% or 90% deferral of higher or lower gas costs such that the impact on current earnings from the gas cost sharing is either 20o/o ot 10Yo of gas cost differences compared to PGA prices, respectively. For the PGA years in Oregon beginning November 1 ,2018, 2017, and 2016, NW Natural selected the 900/0, 90%, and 90% deferral of gas cost differences, respectively. ln Washington, '100% of the differences between the PGA prices and actual gas costs are deferred. See Note 15. NW Natural's financial derivatives policy sets forth the guidelines for using selected derivative products to support prudent risk management strategies within designated parameters. NW Natural's objective for using derivatives is to decrease the volatility of gas prices, earnings, and cash flows without speculative risk. The use of derivatives is permitted only after the risk exposures have been identified, are determined not to exceed acceptable tolerance levels, and are determined necessary to support normal business activities. NW Natural does not enter into derivative instruments for trading purposes. All derivatives for NW Holdings are currently held at NW Natural. Fair Value ln accordance with fair value accounting, we use the following fair value hierarchy for determining inputs for our debt, pension plan assets, and derivative fair value measurements:. Level 1: Valuation is based on quoted prices for identical instruments traded in active markets;. Level 2: Valuation is based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market; and. Level 3: Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect our own estimates of assumptions market participants would use in valuing the asset or liability. When developing fair value measurements, it is our policy to use quoted market prices whenever available or to maximize the use of observable inputs and minimize the use of unobservable inputs when quoted market prices are not available. Fair values are primarily developed using industry-standard models that consider various inputs including: (a) quoted future prices for commodities; (b) forward currency prices; (c) time value; (d) volatility factors; (e) current market and contractual prices for underlying instruments; (f) market interest rates and yield curves; (g) credit spreads; and (h) other relevant economic measures. NW Natural considers liquid points for natural gas hedging to be those points for which there are regularly published prices in a nationally recognized publication orwhere the instruments are traded on an exchange. Goodwill NW Holdings, through its wholly-owned subsidiary NWN Water and NW Water's wholly-owned subsidiaries, has completed various acquisitions that resulted in the recognition of goodwill. Goodwill is measured as the excess of the acquisition-date fair value of the consideration transferred over the acquisition-date fair value of the net identifiable assets assumed. Adjustments are recorded during the measurement period to finalize the allocation of the purchase price. The carrying value of goodwill is reviewed annually during the fourth quarler using balances as of October 1, or whenever events or changes in circumstance indicate that such carrying values may not be recoverable. The goodwill assessment policy begins with a qualitative analysis in which events and circumstances are evaluated, including macroeconomic conditions, industry and market conditions, regulatory environments, and overall financial performance of the reporting unit. lf the qualitative assessment indicates that the carrying value may be at risk of recoverability, a quantitative evaluation is performed to measure the carrying value of the goodwill against the fair value of the reporting unit. The reporting unit is determined primarily based on current operating segments and the level of review provided by the Chief Operating Decision Maker (CODM) and/or segment management on the operating segment's financial results. Reporting unils are evaluated periodically for changes in the corporate environment. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 89 of 210 84 Table of Contents As of December 31 ,2018, NW Holdings had goodwill of $9.0 million. All of NW Holdings'goodwill was acquired in 2018 through the business combinations completed by NWN Water and its wholly-owned subsidiaries. No impairment charges were recorded as a result of the fourth quarter goodwill impairment assessment. lncome Taxes We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences ofevents that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the enactment date period unless, for NW Natural, a regulatory Order specifies deferral of the effect of the change in tax rates over a longer period of time. For NW Natural, deferred income tax assets and liabilities are also recognized for temporary differences where the deferred income tax benefits or expenses have previously been flowed through in the ratemaking process of the NGD business. Regulatory tax assets and liabilities are recorded on these deferred tax assets and liabilities to the extent it is believed they will be recoverable from or refunded to customers in future rates. Deferred investment tax credits on NGD plant additions, which reduce income taxes payable, are deferred for financial statement purposes and amortized over the life of the related plant. lnterest and penalties related to unrecognized tax benefits, if any, are recognized within income tax expense and accrued inlerest and penalties are recognized within the related tax liability line in the consolidated balance sheets. No accrued interest or penalties for uncertain tax benelits have been recorded. See Note 10. Environmental Continqencies Loss contingencies are recorded as liabilities when it is probable a liability has been incurred and the amount of the loss is reasonably estimable in accordance with accounting standards for contingencies Estimating probable losses requires an analysis of uncertainties that often depend upon judgments about potential actions by third parties. Accruals for loss contingencies are recorded based on an analysis of potential results. With respect to environmental liabilities and related costs, estimates are developed based on a review of information available from numerous sources, including completed studies and site specific negotiations. NW Natural's policy is to accrue the full amount of such liability when information is sufficient to reasonably estimate the amount of probable liability. When information is not available to reasonably estimate the probable liability, or when only the range of probable liabilities can be estimated and no amount within the range is more likely than another, it is our policy to accrue at the low end of the range. Accordingly, due to numerous uncertainties surrounding the course of environmental remediation and the preliminary nature of several site investigations, in some cases, it may not be possible to reasonably estimate the high end of the range of possible loss. ln those cases, the nature ofthe potential loss and the fact that the high end of the range cannot be reasonably estimated is disclosed. See Note 17. Subsequent Events We monitor significant events occurring after the balance sheet date and prior to the issuance of the financial statements to determine the impacts, if any, of events on the financial statements to be issued. We do not have any subsequent events to report. Exhibit 3 J. Palfreyman, Falls Water Co., lnc.

During the second quarter of 2018,we moved forward with our long-term strategic plans, which include a shift away from the California gas storage business, by entering into a Purchase and Sale Agreement that provides for the sale of all of the membership interests in Gill Ranch, subject to various regulatory approvals and closing conditions. As such, we reevaluated reportable segments and concluded that the remaining gas storage activities no longer meet the requirements of a reportable segment. lnterstate Storage Services and asset management activities at the Mist gas storage facility are now reported as other under NW Nalural. NW Natural and NW Holdings also have investments and business activities not specifically related to NGD, which are aggregated and reported as other and described below for each entity. No individual customer accounts for over '10olo of NW Holdings' or NW Natural's operating revenues. Natural Gas Distribution The NGD segment is a regulated utility principally engaged in the purchase, sale, and delivery of natural gas and related services to customers in Oregon and southwest Washington. With regulated utility operations, NW Natural is responsible for building and maintaining a safe and reliable pipeline distribution system, purchasing sufficient gas supplies from producers and marketers, contracting for firm and interruptible transportation of gas over interstate plpelines to bring gas from the supply basins into its service territory, and re-selling the gas to customers subject to rates, terms, and conditions approved by the OPUC or WUTC. NGD also includes taking customer-owned gas and transporting it from interstate pipeline connections, or city gates, to the customers'end-use facilities for a fee, which is approved by the OPUC orWUTC. Approximately 89% of NGD customers are located in Oregon and 11o/o in Washington. On an annual basis, residential and commercial customers typically account for around 60% of total NGD volumes delivered and around 90% of NGD margin. lndustrial customers largely account for the remaining volumes and NGD margin. A small amount of the margin is also derived from miscellaneous services, gains or losses from an incentive gas cost sharing mechanism, and other service fees. lndustrial sectors served by NW Natural include: pulp, paper, and other forest products; the manufacture of electronic, electrochemical and electrometallurgical products; the processing of farm and food products; the production of various mineral products; metal fabrication and casting; the production of machine tools, machinery, and textiles; the manufacture of asphalt, concrete, and rubber; printing and publishing; nurseries; and government and educational institutions. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 91 of21O 86 assumed exercise of stock options and the payment of estimated stock awards from other stock-based compensation plans that are outstanding at the end of each period presented. Antidilutive stock awards are excluded from the calculation of diluted earnings or loss per common share. Table of Contents ln addition to NW Natural's local gas distribution business, the NGD segment also includes the portion of the Mist underground storage facility used to serve NGD customers, the North Mist gas storage expansion in Oregon, and NWN Gas Reserves, which is a wholly-owned subsidiary of Energy Corp. NW Natural NW Natural activities included in Other includes lnterstate Storage Services and third-party asset management services for the Mist facility in Oregon, appliance retail center operations, and corporate operating and non-operating revenues and expenses that cannot be allocated to NGD operations. Earnings from lnterstate Storage Services assets are primarily related to firm storage capacity revenues. Earnings from the Mist facility also include revenue, net of amounts shared with NGD customers, from management of NGD assets at Mist and upstream pipeline capacity when not needed to serve NGD customers. Historically, under the Oregon sharing mechanism, NW Natural retained 80% of the pretax income from these services when the costs of the capacity were not included in NGD rates, or 33% of the pre{ax income when the costs have been included in these rates. The remaining 20o/o and 670/o, respectively, were recorded to a deferred regulatory account for crediting back to NGD customers. After November 1 ,2018 NW Natural retains 1 0% of the pre-tax income when the costs have been included in these rates, and the remaining 90% is recorded to a deferred regulatory account for crediting back to NGD customers. ln thousands NGD NW Holdings NW Holdings'activities included in Other includes all remaining activities not associated with NW Natural, specifically NWN Water, which consolidates the water operations and is pursuing other investments in the water sector itself and through its wholly-owned subsidiaries, NWN Gas Storage, a wholly-owned subsidiary of NWN Energy, NWN Energy's equity investment in TWH, which is pursuing development of a cross- Cascades transmission pipeline project (TWP), and other pipeline assets in NNG Financial. For more information on TWP, see Note 13. Other also includes corporate revenues and expenses that cannot be allocated to other operations. All prior period amounts have been retrospeclively adjusted to reflect the change in reportable segments and the designation of Gill Ranch as a discontinued operation for NW Holdings, and the designation of subsidiaries previously owned by NW Natural that are now owned by NW Holdings as discontinued operations for NW Natural.

Natural Gas Margin NGD margin is a financial measure used by the CODM, consisting of NGD operating revenues, reduced by the associated cost of gas, environmental recovery revenues, and revenue taxes. The cost of gas purchased for NGD customers is generally a pass{hrough cost in the amount of revenues billed to regulated NGD customers. Environmental recovery revenues represent collections received from customers through the environmental recovery mechanism in Oregon. These collections are offset by the amortization of environmental liabilities, which The following table presents additional segment information concerning NGD margin ln thousands is presented as environmental remediation expense in operating expenses. Revenue taxes are collected from NGD customers and remitted to taxing authorities. The collections from customers are offset by the expense recognition of the obligation to the taxing authority. By subtracting cost ofgas, environmental remediation expense, and revenue taxes from NGD operating revenues, NGD margin provides a key metric used by the CODM in assessing the performance of the NGD segment. 2018 2017 2016 NGD margin calculation: NGD operating revenues Less: NGD cost of gas Environmental remedtation expense Revenue taxes{') NGD margin o) $680,648 $ 255,743 11,127 30,082 732,942 $ 325,019 15,291 650,477 260,588 13,298 383,696 $392,632 $ 376,59'l The change in presentation of revenue taxes was a result of the adoption of ASU 2014-09 "Revenue From Contracts with Customers" and all related amendments on January 1 , 201 8.

COMMON SrOCK As part of the reorganization of NW Holdings and NW Natural into a holding company structure effective October 'l ,2018, NW Natural shareholders automatically became shareholders of NW Holdings on a one-for-one share basis with the same number of shares and same relative ownership percentage in NW Holdings as was held in NW Natural immedialely prior to the reorganization. As of December 31 , 2018, NW Holdings had 100 million shares of common stock authorized. As of December 31, 2018 and 20'l7, NW Natural had 100 million shares of common stock authorized. As of December 31, 201 8, NW Holdings had 24,339 shares reserved for issuance of common stock under the Employee Stock Purchase Plan (ESPP) and 394,204 shares reserved for issuance under the Dividend Reinvestment and Direct Stock Purchase Plan (DRPP). At NW Holdings' election, shares sold through the DRPP may be purchased in the open market or through original issuance of shares reserved for issuance under the DRPP. The Restated Stock Option Plan (SOP) was terminated with respect to new grants in2012: however, options granted before the Restated SOP was terminated remain outstanding until the earlier of their expiration, forfeiture, or exercise. Options are now exercisable for shares of NW Holdings common stock. There were 55,938 options outstanding at December 31 ,2018, which were granted prior to termination of the plan During November 2016, NW Natural completed an equity issuance consisting ofan offering of880,000 shares of common stock along with a 30-day option for the underwriters to purchase an additional 132,000 shares. The offering closed on November 16, 2016 and resulted in a total issuance of 1,012,000 shares as both the initial offering and the underwriter option were fully executed. All shares were issued on November 16, 2016 at an offering price of $54.63 per share and resulted in total net proceeds of $52.8 million. Stock Repurchase Proqram NW Holdings has a share repurchase program under which it may purchase its common shares on the open market or through privately negotiated transactions. NW Holdings currently has Board authorization through May 201 9 to repurchase up to an aggregate of the greater of 2.8 million shares or $100 million. No shares of common stock were repurchased pursuant to this program during the year ended December 31, 2018. Since the plan's inception in 2000 under NW Natural, a total of 2.1 million shares have been repurchased at a total cost of $83.3 million. Exhibit 3 J. Palfreyman, Falls Water Co., lnc.

Revenue from contracts with customers contain one performance obligation that is generally satisfied over time, using the output method based on time elapsed, due to the continuous nature ofthe service provided. The transaction price is determined per a set price agreed upon in the contract or dependent on regulatory tariffs. Customer accounts are settled on a monthly basis or paid at time of sale and based on historical experience. lt is probable that we will collect substantially all of the consideration to which we are entitled. NW Holdings and NW Natural do not have any material contract assets, as net accounts receivable and accrued unbilled revenue balances are unconditionaland only involve the passage of time until such balances are billed and collected. NW Holdings and NW Natural do not have any material contract liabilities. Revenue-based taxes are primarily franchise taxes, which are collected from NGD customers and remitted to taxing authorities. Beginning January 1,2018, revenue taxes are included in operating revenues with an equal and offsetting expense recognized in operating expenses in the consolidated statements of comprehensive income. Natural Gas Distribution Natural gas sa/es. NW Natural's primary source of revenue is providing natural gas to customers in the NGD service territory, which includes residential, commercial, industrial and transportation customers. NGD revenue is generally recognized over time upon delivery of the gas commodity or service to the customer, and the amount of consideration received and recognized as revenue is dependent on the Oregon and Washington tariffs. Customer accounts are to be paid in full each month, and there is no right of return or warranty for services provided. Revenues include firm and interruptible sales and transportation services, franchise taxes recovered from the customer, late payment fees, service fees, and accruals for gas delivered but not yet billed (accrued unbilled revenue). The accrued unbilled revenue balance is based on estimates of deliveries during Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 94 ot210 89 Table of Contents the period from the last meter reading and management judgment is required for a number of factors used in this calculation, including customer use and weather factors. We applied the significant financing practical expedient and have not adjusted the consideration NW Natural expects to receive from NGD customers for the effects of a significant financing component as all payment arrangements are settled annually. Due to the election of the right to invoice practical expedient, we do nol disclose the value of unsatisfied performance obligations as of December 31 ,20'|8. Alternative revenue. Weather normalization (WARM) and decoupling mechanisms are considered to be alternative revenue programs. Alternative revenue programs are considered to be contracts between NW Natural and its regulator and are excluded from revenue from contracts with customers. Leasing revenue. Leasing revenue primarily consists of rental revenue for small leases of property owned for NGD to third parties. The majority ofthe transactions are accounted for as operating leases and the revenue is recognized on a straight-line basis over the term of the lease agreement. Lease revenue is excluded from revenue from contracts with customers. NW Natural Other Gas storage revenue. NW Natural's other revenue includes gas storage activity, which includes lnterstate Storage Services used to store natural gas for customers. Gas storage revenue is generally recognized over time as the gas storage service is provided to the customer and the amount of consideration received and recognized as revenue is dependent on set rates defined per the storage agreements. Noncash consideration in the form of dekatherms of natural gas is received as consideration for providing gas injection services to gas storage customers. This noncash consideration is measured at fair value using the average spot rate. Customer accounts are generally paid in full each month, and there is no right of return or warranty for services provided. Revenues include firm and interruptible storage services, net of the profit sharing amount refunded to NGD customers. Asset management revenue. Asset management revenue is generally recognized over time using a straight-line approach over the term of each contract, and the amount of consideration received and recognized as revenue is dependent on a variable pricing model. Variable revenues earned above guaranteed amounts are estimated and 7. STOC K.BAS ED COMPEN SATI O N recognized at the end of each period using the most likely amount approach. Revenues include the optimization of the storage assets and pipeline capacity provided, net of the profit sharing amount refunded to NGD customers. Asset management accounts are settled on a monthly basis. As of December 31,2018, unrecognized revenue for the fixed component of the transaction price related to gas storage and asset management revenue was approximately $56.0 million. Of this amount, approximately $'14.1 million will be recognized in 201 9, $1 1.7 million in 2020, $1 0.7 million in 2021,$7.0 million in 2022,$5.8 million in 2023, and $6.7 million thereafter. The amounts presented here are calculated using current contracted rates. On October 12,2018, NW Natural filed a rate petition with FERC for revised maximum cost-based rates, which incorporated the new federal corporate income tax rate. The revised rates became effective November 1,2018. Appliance retail center revenue. NW Natural owns and operates an appliance store that is open to the public, where customers can purchase natural gas home appliances. Revenue from the sale of appliances is recognized at the point in time in which the appliance is transferred to the third party responsible for delivery and installation services and when the customer has legal title to the appliance. lt is required that the sale be paid for in full prior to transfer of legal title. The amount of consideration received and recognized as revenue varies with changes in marketing incentives and discounts offered to customers. NW Holdings Other NW Holdings'primary source of other revenue is providing water distribution services to customers. Water distribution revenue is generally recognized over time upon delivery of the water commodity or service to the customer, and the amount of consideration received and recognized as revenue is dependent on the Oregon, Washington and ldaho tariffs. Customer accounts are to be paid in full each month, and there is no right of return or warranty for services provided. We applied the significant financing practical expedient and have not adjusted the consideration we expect to receive from water distribution customers for the effects of a significant financing component as all payment arrangements are settled annually. Due to the election of the right to invoice practical expedient, we do not disclose the value of unsatisfied performance obligations as of December 31, 2018. Stock-based compensation plans are designed to promote stock ownership in NW Holdings by employees and officers. These compensation plans include a Long Term lncentive Plan (LTIP), an ESPP, and a Restated SOP. Long Term lncentive Plan The LTIP is intended to provide a flexible, competitive compensation program for eligible officers and key employees. Under the LTIP, shares of NW Holdings common stock are authorized for equity incentive grants in the form of stock, restricted stock, restricted stock units, stock options, or performance shares. An aggregate of 1,100,000 shares were authorized for issuance as of December 31,2018. Shares awarded under the LTIP may be purchased on the open market or issued as original shares. Of the 1,100,000 shares of common stock authorized for LTIP awards at December 3'1 , 2018, there were 574,787 shares available for issuance under any type of award. This Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 95 of 210 90 Table of Contents assumes market, performance, and service-based grants currently outstanding are awarded at the target level. There were no outstanding grants of restricted stock or stock options under the LTIP at December 31 , 201 8 or 2017 . The LTIP stock awards are compensatory awards for which compensation expense is based on the fair value of stock awards, with expense being recognized over the performance and vesting period ofthe outstanding awards. Forfeitures are recognized as they occur. Performance Shares Since the LTIP's inception in 2001, performance shares, which incorporate market, performance, and service-based factors, have been granted annually with three-year performance periods. The following table summarizes performance share expense information: Expense During Total Expense Dottars in thousands Shares(') Award Year(2) for Award Estimated award: 201&2018 granto 28,218 $ 598 $ 1,413 Actual award: 2O1s2O17 gtanl 18,3(x (346) 1,'169 2014-2016grant 31,388 168 1,685(1) ln addition to common stock shares, a participant also receives a dividend equivalent cash payment equal to the number of shares of common stock received on the award payout multiplied by the aggregate cash dividends paid per share during the performance period.o Amount represents the expense recognized in the third year of the vesting period noted above. For the 2015-2017 gtanl, targets were not met and expense was reversed during 201 7 that had been previously recognized.(') This represents the estimated number of shares to be awarded as of December 31 , 201 8 as certain performance share measures have been achieved. Amounts are subject to change with final payout amounts authorized by the Board of Directors in February 2019. The aggregate number of performance shares granted and oulstanding at the target and maximum levels were as follows: the performance of the Russell 2500 Utilities lndex over the three-year performance period and a growth modifier based on accumulative EBITDA measure. For the 2018-2020 performance period, performance share awards are based on the achievement of a three-year ROIC threshold that must be met and a cumulative EPS factor, which can be modified by a TSR factor relative to the performance of the Russell 2500 Utilities lndex over the three-year performance period. The 20'18-2020 performance period allows for one of the performance factors to remain variable until the first quarter of the third year of the award period. As the performance factor will not be approved until the first quarter of 2020, there is not a mutual understanding of the award's key terms and conditions between NW Natural and the participants as of December 31, 201 8, and therefore, no expense was recognized for the 2018-2020 performance period. NW Natural will calculate the grant date fair value and recognize expense once the final performance factor has been approved. lf the target was achieved forthe 2018 award, NW Holdings would grant 34,702 shares in the first quarter of 2020. Compensation expense is recognized in accordance with accounting standards for stock-based compensation and calculated based on performance levels achieved and an estimated fair value using the Monte-Carlo method. The weighted-average grant date fair value of nonvested shares at December31,2018 and 2017 was $57.05 and $56.40 per share, respectively. The weighted-average grant date fair value of shares vested during the year was $56.23 per share and there were no performance shares granted during the year for accounting purposes. Asof December3l, 2018, therewas $1.1 million of unrecognized compensation expense related to the nonvested porlion of performance awards expected to be recognized through 2019. Restricted Stock Units !n2012, RSUs began being granted underthe LTIP instead ofstock options under the Restated SOP. Generally, the RSUs awarded are forfeitable and include a performance-based threshold as well as a vesting period of four years from the grant date. Upon vesting, the RSU holder is issued one share of common stock plus a cash payment equal to the total amount of dividends paid per share between the grant date and vesting date of that portion of the RSU. The fair value of an RSU is equal to the closing market price of NW Holdings' common stock on the grant date. During 2018, total RSU expense was $1 .8 million compared to $1 .6 million in 2017 and $1 .5 million in 201 6. As of December 31 , 2018, there was $3.1 million of unrecognized compensation cost from grants of RSUS, which is expected to be recognized over a period extending through 2023. Exhibit 3 J.

Additionally, these plans are based on performance results achieved relative to specific core and non-core strategies (strategic factor).

Palfreyman, Falls Water Co., lnc. Page 97 of 210 Table of Contents 8. DEBT Short-Term Debt The primary source of short-term liquidity for NW Holdings is cash balances, dividends from its operating subsidiaries, in particular NW Natural, available cash from a multi-year credit facility, and short{erm credit facilities it may enter into from time to time. The primary source of shortterm liquidity for NW Natural is from the sale of commercial paper and bank loans. NW Natural has a commercial paper program, and NW Holdings and NW Natural have separate bank facilities. ln addition to issuing commercial paper or bank loans to meet working capital requirements, including seasonal requirements to finance gas purchases and accounts receivable, short-term debt may also be used to temporarily fund capital requirements. For NW Natural, commercial paper and bank loans are periodically refinanced through the sale of long{erm debt or equity contributions from NW Holdings. NW Natural's commercial paper is sold through two commercial banks under an issuing and paying agency agreement and is supported by one or more unsecured revolving credit facilities. See "Credrt Agreements" below. At December 31 ,2018 and 2017 , NW Holdings had shortterm debt outstanding of $217.6 million and $54.2 million, respectively, substantially all of which was recorded at NW Natural and was comprised primarily of NW Natural's commercial paper. The weighted average interest rate of commercial paper outstanding at December 31 2018 and 2017 was 3.0% and 1.9%, respectively. The carrying cost of commercial paper approximates fair value using Level 2 inputs, due to the short{erm nature of the noles. See Note 2 for a description of the fair value hierarchy. At December 31 , 201 8, NW Natural's commercial paper had a maximum remaining maturity of 46 days and an average remaining maturity of 22 days. Credit Agreements NW Holdings ln October 2018, NW Holdings entered into a $100.0 million credit agreement, with a feature that allows it to request increases in the total commitment amount, up to a maximum of $150.0 million. The maturity date of the agreement is October 2,2023, with available extensions of commitments for two additional one-year periods, subject to lender approval. The NW Holdings credit agreement permits the issuance of letters of credit in an aggregate amount of up to $40.0 million. The principal amount of borrowings under the credit agreement is due and payable on the maturity date. The credit agreement requires NW Holdings to maintain a consolidated indebtedness to total capitalization ratio of 70% or less. Failure to comply with this covenant would entitle the lenders to terminate their lending commitments and accelerate the maturity of all amounts outstanding. NW Holdings was in compliance with this covenant at December 3 1, 201 8. The agreement also requires NW Holdings lo maintain debt ratings (which are defined by a formula using NW Natural's credit ratings in the event NW Holdings does not have a credit rating) with Standard & Poor's (S&P) and Moody's lnvestors Service, lnc. (Moody's) and notify the lenders of any change in its senior unsecured debt ratings or senior secured debt ratings, as applicable, by such rating agencies. A change in NW Holdings'debt ratings by S&P or Moody's is not an event of default, nor is the maintenance of a specific minimum level of debt rating a condition of drawing upon the credit agreement. Rather, interest rates on any loans outstanding underthe credit agreements are tied to debt ratings and therefore, a change in the debt rating would increase or decrease the cost of any loans under the credit agreements when ratings are changed. NW Holdings does not currently maintain ratings with S&P or Moody's. There were no outstanding balances and no letters of credit issued or outstanding under the NW Holdings agreement at December 31 , 2018. NW Holdings had $2.8 million of letters of credit issued and outstanding, separate from the aforementioned credit agreement, at December 31, 2018. NW Natural ln October 2018, NW Natural entered into a new multi-year credit agreement for unsecured revolving loans totaling $300.0 million, with a feature that allows NW Natural to request increases in the total commitment amount, up to a maximum of $450.0 million. The maturity date of the agreement is October 2,2023 with available extensions of commitments for two additional one-year periods, subject to lender approval. The new credit agreement is substantially similar to the prior credit agreement which was terminated upon the closing of the New Credit Agreement. The new credit agreement permits the issuance of letters of credit in an aggregate amount of up to $60.0 million. The principal amount of borrowings under the credit agreement is due and payable on the maturity date. There were no outstanding balances under NW Natural's prior credit agreement or the new credit agreement and no letters of credit issued or outstanding at December 31, 2018 and 2017. NW Natural's prior credit agreement and the new credit agreement require NW Natural to maintain a consolidated indebtedness to total capitalization ralio ot 70o/o or less. Failure to comply with this covenant would entitle the lenders to terminate their lending commitments and accelerate the maturity of all amounts outstanding. NW Natural was in compliance with this covenant at December 31 , 2018 and 2017 . The new credit agreement also requires NW Natural to maintain credit ratings with S&P and Moody's and notify the lenders of any change in NW Natural's senior unsecured debt ratings or senior secured debt ratings, as applicable, by such rating agencies. A change in NW Natural's debt ratings by S&P or Moody's is not an event of default, nor is the maintenance of a specific minimum level of debt rating a condition of drawing upon the new credit agreement. Rather, interest rates on any loans outstanding under the new credit agreement are tied to debt ratings and therefore, a change in the debt rating would increase or decrease the cost of any Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 98 of 210 93 Table of Contents loans under the new credit agreement when ratings are changed. Long-Term Debt NW Natural's issuance of FMBs, which includes NW Natural's medium- term notes, under the Mortgage and Deed of Trust (Mortgage) is limited by eligible property, adjusted net eamings, and other provisions of the Mortgage.

NW Natural also has a qualified defined contribution plan (Retirement K Savings Plan) for all eligible employees. The qualified defined benefit pension plan and Retirement K Savings Plan have plan assets, which are held in qualified trusts to fund retirement benefits. Effective January 1,2007 and 2010, the qualified defined benefit pension plans and postretirement benefits for non-union employees and union employees, respectively, were closed to new participants. Non-union and union employees hired or re-hired after December 31, 2006 and 2009, respectively, and employees of NW Natural subsidiaries are provided an enhanced Retirement K Savings Plan benefit.

A total of $0.6 million will be amortized from AOCL to earnings related to actuarial losses in 2019. The assumed discount rate for NW Natural's pension plan and other postretirement benefit plans was determined independently based on the FTSE Above Median Curve (discount rate curve), which uses high quality corporate bonds rated AA- or higher by S&P or Aa3 or higher by Moody's. The discount rate curve was applied to match the estimated cash flows in each of the plans to reflect the timing and amount of expected future benefit payments for these plans. The assumed expected long-term rate of return on plan assets for NW Natural's qualified pension plan was developed using a weighted- average of the expected returns for the target asset portfolio. ln developing the expected long-term rate ofreturn assumption, consideration $(8,438) $(6,951) (2,7e4) 1,052 946 1,694 (444) (1,848) 1,250 (1,4871 (7,188) $(8,438) was given to the historical performance of each asset class in which the plan's assets are invested and the target asset allocation for plan assets. The investment strategy and policies for qualified pension plan assets held in the retirement trust fund were approved by the NW Natural Retirement Committee, which is composed of senior management with the assistance of an outside investment consultant. The policies set forth the guidelines and objectives governing the investment of plan assets. Plan assets are invested for total return with appropriate consideration for liquidity, portfolio risk, and return expectations. All investments are expected to satisfy the prudent investments rule under the Employee Retirement lncome Security Act of 1974. The approved asset classes may include cash and short-term investments, fixed income, common stock and convertible securities, absolute and real return strategies, and real estate. Plan assets may be invested in separately managed accounts or in commingled or mutual funds. lnvestment re-balancing takes place periodically as needed, or when significant cash flows occur, in order to maintain the allocation of assets Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 102 of210 642 361 $ 96 ln thousands Table of Contents within the stated target ranges. The retirement trust fund is not currently invested in NW Holdings or NW Natural securities. The following table presents the NW Natural pension plan asset target allocation at December 31 , 2018: Asset Category Target Allocation These are unfunded, non{ualified plans with no plan assets; however, a significant portion of the obligations is indirectly funded with company and trustowned life insurance and other assets. Other postretirement benefit plans are unfunded plans but are subject to regulatory deferral. The actuarial gains and losses, prior service costs, and transition assets or obligations for these plans are recognized as a regulatory asset. Net periodic benefit costs consist of service costs, interest costs, the expected returns on plan assets, and the amortization of gains and losses and prior service costs. The gains and losses are the sum of the actuarial and asset gains and losses throughout the year and are amortized over the average remaining service period of active participants. The asset gains and losses are based in part on a market- related valuation of assets. The market-related valuation reflects differences between expected returns and actual investment returns with the differences recognized over a two-year period from the year in which they occur, thereby reducing yearto-year net periodic benefit cost volatility.

On October 26, 2018 the OPUC ordered that the balancing account be frozen as of October 31,2018, with recovery subject to future proceedings. Effective November 'l , 2018 the OPUC authorized an additional $8.1 million to be included in rates for defined benefit pension plan expenses. 97 Exhibit 3 J. Palfreyman, Falls Water Co., lnc.

These trend rates apply to both medical and prescription drugs. Medical costs and prescription drugs are assumed to decrease gradually each year to a 'ale ot 4.75o/o by 2025. Assumed health care cost trend rates can have a significant effect on the amounts reported for the health care plans; however, other postretirement benefit plans have a cap on the amount of costs reimbursable by NW Natural.

The Pension Protection Act of 2006 (the Act) established funding requirements for defined benefit plans. The Act establishes a 100o/o funding target over seven years for plan years beginning after December 31 , 2008. ln 2012 the Moving Ahead for Progress in the 21st Century Act (MAP-21) legislation changed several provisions affecting pension plans, including temporary funding relief and Pension Benefit Guaranty Corporation (PBGC) premium increases, which reduces the level of minimum required contributions in the nearterm but generally increases contributions in the long-run and increases the operational costs of running a pension plan. ln 2014, the Highway and Transporlation Funding Act (HATFA) was signed and extended funding relief for an additional five years. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 104 o1210 98 Table of Contents The qualified defined benefit pension plan was underfunded by $162.4 million at December 31, 2018. lncluding the impacts of MAP-21 and HATFA, NW Natural made cash contributions totaling $15.5 million to its qualified defined benefit pension plan for 2018. During 2019, NW Natural expects to make contributions of approximately $'l 1.0 million to this plan. Multiemplover Pension Plan ln addition to the NW Natural-sponsored defined benefit plans presented above, prior to 2014 NW Natural contributed to a multiemployer pension plan for its NGD union employees known as the Western States Office and Professional Employees lnternational Union Pension Fund (Western States Plan). The plan's employer identification number is 94- 6076144. Effective December 22, 2013, NW Natural withdrew from the plan, which was a noncash transaction. Vested participants will receive all benefits accrued through the date of withdrawal. As the plan was underfunded at the time of withdrawal, NW Natural was assessed a withdrawal liability of $8.3 million, plus interest, which requires NW Natural to pay $0.6 million each year to the plan for 20 years beginning in July 2014. The cost of the withdrawal liability was deferred to a regulatory account on the balance sheet. Payments were $0.6 million for 2018, and as of December 31, 2018 the liability balance was $6.8 million. For 2017 and 2016, contributions to the plan were $0.6 million and $0.6 million, respectively, which was approximately 4o/o lo 60/o of the total contributions to the plan by all employer participants in those years. Defined Co Plan NW Natural's Retirement K Savings Plan is a qualified defined contribution plan under lnternal Revenue Code Sections 401(a) and 401 (k). NW Natural contributions totaled $6.5 million, $5.4 million, and $4.6 million for 2018,2017, and 2016, respectively. The Retirement K Savings Plan includes an Employee Stock Ownership Plan. Deferred Gompensation Plans NW Natural's supplemental deferred compensation plans for eligible officers and senior managers are non-qualified plans. These plans are designed to enhance the retirement savings of employees and to assist them in strengthening their financial security by providing an incentive to save and invest regularly. Fair Value Below is a description of the valuation methodologies used for assets measured at fair value. ln cases where NW Natural's pension plan is invested through a collective trust fund or mutual fund, the fund's market value is utilized. Market values for investments directly owned are also utilized. U.s. EQulTY. These are non-published net asset value (NAV) assets. The non-published NAV assets consist of commingled trusts where NAV is not published but the investment can be readily disposed of at NAV or market value. The underlying investments in lhis asset class includes investments primarily in U.S. common stocks. INTERNATIONAUGLOBAL EQUIW. These are Level 1 and non-published NAV assets. The Level 1 asset is a mutual fund, and the non-published NAV assets consist of commingled trusts where the NAV/unit price is not published but the investment can be readily disposed of at the NAV/unit price. The mutual funds has a readily determinable fair value, including a published NAV, and the commingled trusts are valued at unit price. This asset class includes investments primarily in foreign equity common stocks. LlABlLlw HEDGING. These are non-published NAV assets. The non- published NAV assets consist of commingled trusts where NAV is not published but the investment can be readily disposed of at NAV or market value. The underlying investments in this asset class include long duration fixed income investments primarily in U.S. treasuries, U.S government agencies, municipal securities, mortgage-backed securities, asset-backed securities, as well as U.S. and international investmentgrade corporate bonds. OPPORTUNISTIC. These are non-published NAV assets consisting of commingled trusts where the investments can be readily disposed of at unit price, and a hedge fund of funds where the valuation is not published. This hedge fund of funds is winding down. Based on recent dispositions, NW Natural believes the remaining investment is fairly valued. The hedge fund of funds is valued at the weighted average value of investments in various hedge funds, which in turn are valued at the closing price of the underlying securities. This asset class includes investments in emerging market debt, leveraged loans, RElTs, high yield bonds, a commodities fund, and a hedge fund offunds ABSOLUTE RETURN STRATEGY. This is a non-published NAV asset consisting of a hedge fund of funds where the valuation is not published This hedge fund of funds is winding down. Based on recent dispositions, NW Natural believes the remaining investment is fairly valued. The hedge fund of funds is valued at the weighted average value of investments in various hedge funds, which in turn are valued at the closing price of the underlying securities. This asset class primarily includes investments in common stocks and fixed income securities. CASH AND CASH EQUIVALENTS. These are Level 1 and non-published NAV assets. The Level 1 assets consist of cash in U.S. dollars, which can be readily disposed of at face value. The non-published NAV assets represent mutual funds without published NAV's but the investment can be readily disposed of at the NAV. The mutual funds are valued at the NAV of the shares held by the plan at the valuation date. The preceding valuation methods may produce a fair value calculation that is not indicative of net realizable value or reflective of future fair values. Although we believe these valuation methods are appropriate and consistent with other market participants, lhe use of different methodologies or assumptions to determine the fair value of certain investments could result in a different fair value measurement at the reporting date. lnvestment securities are exposed to various financial risks including interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of NW Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 105 of21O 99 Table of Contents Natural's investment securities will occur in the near term and such changes could materially affect NW Natural's investment account balances and the amounts reported as plan assets available for benefit payments.

These regulatory income tax assets primarily represent future rate recovery ofdeferred tax liabilities, resulting from differences in NGD plant financial slalement and tax bases and NGD plant removal costs, which were previously flowed through for rate making purposes and to take into account the additional future taxes, which will be generated by that recovery. These deferred tax liabilities, and the associated regulatory income tax assets, are currently being recovered through customer rates. At December 31, 20'18 and 2017, regulatory income tax assets of $2.3 million and $0.9 million, respectively, were recorded by NW Natural, representing future recovery of deferred tax liabilities resulting from the equity portion of AFUDC. At December 31, 2018 and 2017, deferred tax assets of $57.5 million and $56.5 million, respectively, were recorded by NW Natural representing the future income tax benefit associated with the excess deferred income tax regulatory liability recorded as a result of the lower federal corporate income tax rate provided for by the TCJA. At December 31 , 2018 and 20't 7, regulatory liability balances representing the net tax benefit of the change in deferred taxes as a result of the TCJA ot $217 .1 million and $213.3 million, respectively, were recorded by NW Natural. NW Natural's natural gas utility rates include an allowance to provide for the recovery of the anticipated provision for income taxes incurred as a result of providing regulated services. As a result of the 21 percent federal corporate income tax rate enacted in 2017 , NW Natural recorded an additional regulatory liability in 20'18 reflecting the estimated net reduction in the provision for income taxes. This revenue deferral is based on the estimated net benefit to customers and includes a gross- up for income taxes. As of December 31,2018, a regulatory liability of $8.2 million, including accrued interest, was recorded to reflect this estimated revenue deferral. NW Holdings and NW Natural assess the available positive and negative evidence to estimate if sufficient taxable income will be generated to utilize their respective existing Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 108 of210 101 Table of Contents deferred tax assets. Based upon this assessment, NW Holdings and NW Natural determined that it is more likely than not that all of their respective deferred tax assets recorded as of December 3 l , 2018 will be realized. Uncertain tax positions are accounted for in accordance with accounting standards that require an assessment of the anticipated settlement outcome of material uncertain tax positions taken in a prior year, or planned to be taken in the current year. Until such positions are sustained, the uncertain tax benefits resulting from such positions would not be recognized. No reserves for uncertain tax positions were recorded as of December 31, 2018, 2017, ot 2016. NW Holdings files a consolidated U.S. federal income tax return that includes NW Natural. lncome tax expense is allocated on a separate company basis. The federal income tax returns for tax years 2014 and earlier are closed by statute. The IRS Compliance Assurance Process (CAP) examination of the 201 5, and 201 6 tax years have been completed. There were no material changes to these returns as filed. The 2017 and 2018 tax years are currently under IRS CAP examination. Our 2019 CAP application has been accepted by the lRS. Under the CAP program, NW Holdings and NW Natural work with the IRS to identify and resolve material tax matters before the tax return is filed each year. As of December 31 , 2018, income tax years 201 5 through 201 8 remain open for state examination. The State of Oregon is currently examining the Oregon corporate income tax returns for tax years 201 5, 2016, and 2017. No material changes are anticipated as a result of this examination. U.S. Federal TCJA Matters On December 22,2017, the TCJA was enacled and lowered the U.S. federal corporate income tax rate lo 21o/o from the existing maximum rate of 35%, effective for the tax year beginning January 1, 2018. The TCJA included specific provisions related to regulated public utilities that provided for the continued deductibility of interest expense and the elimination of bonus tax depreciation for property both acquired and placed in service on or after January 1,2018. Under pre-TCJA law, business interest was generally deductible in the determination of taxable income. The TCJA imposed a new limitation on the deductibility of net business interest expense in excess of approximately 30 percent of adjusted taxable income. Taxpayers operating in the trade or business of a regulated utility are excluded from these new interest expense limitations. Proposed U.S. Treasury Regulations were published in November of 2018 which provide a de minimis rule whereby if 90 percent or more of a taxpayer's adjusted asset basis is allocable to regulated utility activities, then all of the business interest expense of that taxpayer is deemed to be excepted business interest of the regulated utility activity and is thereby not limited under the TCJA. As a result of the de minimis rule, NW Holdings and NW Natural anticipate that business interest expense will not be limited under the TCJA. The TCJA generally provides for immediate full expensing for qualified property both acguired and placed in service after September 27 ,2017 and before January 1 , 2023. This would generally provide for accelerated cost recovery for capital investments. However, the definition of qualified property excludes property used in the trade or business of a regulated utility. Proposed U.S. Treasury Regulations were published in August of 2018 which indicated that bonus tax depreciation would not be available for regulated utility activity assets acquired and placed in service by NW Holdings or NW Natural on or after January 1,2018, but bonus tax depreciation would be available for regulated utility activity assets acquired and placed in service by NW Holdings or NW Natural before January 1,2018. The SEC staff previously issued Staff Accounting Bulletin 1 18, which provided guidance on accounting for the tax effects of the TCJA. SAB 1 18 provided a measurement period that should not extend beyond one year from the TCJA enactment date for companies to complete the accounting for the TCJA under ASC 740. To the extent that a company's accounting for certain income tax effects of lhe TCJA was incomplete but a reasonable estimate could be made, a company would record a provisional estimate in the financial statements. NW Natural previously disclosed that due to uncertainties with respect to the availability of bonus tax depreciation for regulated utility activity assets under the TCJA that the effects of bonus tax depreciation for assets placed in service after September 27 ,20'17 but before January 1 , 20'l 8 had not been recorded. The determination to exclude all assets placed in service after September 27, 2017 bul before January 1 , 20 1 8 from bonus tax depreciation was provisional as provided for under SAB 1 18. As a result of the Proposed Regulations on bonus tax depreciation published in August of 2018, NW Natural revised the provisional estimate of deferred taxes and income taxes payable to reflect the effects of bonus tax depreciation for assets placed in service after September 27 , 2017 but before January 1 ,2018. ln the third quarter, NW Natural recognized increases to prepaid income tax of $7.4 million, deferred income tax liability of $4.1 million, and regulatory liability of $3.3 million. ln the fourth quarter, NW Natural recognized additional increases to prepaid income tax of $0.5 million, deferred income tax liability of $0.3 million, and regulatory liability of $0.2 million. The accounting for income tax effects of the TCJA is now complete. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 1 10 of 210 102 Table of Contents 11. PROPERTY, PLANT, AND EQUIPMENT The following table sets forth the major classifications of property, plant, and equipment and accumulated depreciation at December 31: ln lhousands 2018 2017 Accumulated depreciation does not include the accumulated provision for asset removal costs of $380.5 million and $360.9 million at December 31 , 201 I and 201 7, respectively.

NW Holdings Other plant balances include longJived assels associated with water operations and non-regulated activities not held by NW Natural or its subsidiaries. NW Natural Other plant balances include longJived assets not related to NGD. The weighted average depreciation rate for NGD assets was 2.8% during 2018, 20'17 , and 2016.

Gas reserves are stated at cost, net of regulatory amortization, with the associated deferred tax benefits recorded as liabilities in the consolidated balance sheets. The investment in gas reserves provides long-term price protection for NGD customers through the original agreement with Encana Oil & Gas (USA) lnc. under which NW Natural invested $178 million and the amended agreement with Jonah Energy LLC under which an additional $10 million was invested. NW Natural entered into the original agreements with Encana in 2011 under which NW Natural holds working interests in certain sections of the Jonah Field. Gas produced in these sections is sold at prevailing market prices, and revenues from such sales, net ofassociated operating and production costs and amortization, are credited to the NGD cost of gas. The cost of gas, including a carrying cost for the rate base investment, is included in the annual Oregon PGA filing, which allows NW Natural to recover these costs through cuslomer rates. The investment under the original agreement, less accumulated amortization and deferred taxes, earns a rate of return. ln March 2014, NW Natural amended the original gas reserves agreement in order to facilitate Encana's proposed sale of its interest in the Jonah field to Jonah Energy. Underthe amendment, NW Natural ended the drilling program with Encana, but increased its working interests in its assigned sections of the Jonah field. NW Natural also retained the right to invest in new wells with Jonah Energy. Under the amended agreement there is still the option to invest in additional wells on a well-by-well basis with drilling costs and resulting gas volumes shared at NW Natural's amended proportionate working interest for each well in which it invests. NW Natural elected to participate in some of the additional wells drilled in 20'14, but did not participate in additional wells since 2014. However, there may be the opportunity to participate in more wells in the future. Gas produced from the additional wells is included in the Oregon PGA at a fixed rale o1$0.4725 per therm, which approximates the 1O-year hedge rate plus financing costs at the inception of the investment.

The amount in the above table is reported at cash surrender value, net of policy loans. lnvestments in Gas Pioeline TWP, a wholly-owned subsidiary of TWH, is pursuing the development of a new gas transmission pipeline that would provide an interconnection with NW Natural's NGD system. NWN Energy, a wholly-owned subsidiary of NW Holdings, owns 50% of TWH, and 50% is owned by TransCanada American lnvestments Ltd., an indirect wholly-owned subsidiary of TransCanada Corporation. Variable lnterest Entity (VlE) Analysis TWH is a VlE, with NW Holdings'investment in TWP reported under equity method accounting. lt has been determined that NW Holdings is not the primary beneficiary of TWH's activities as it only has a 50% share of the entity, and there are no stipulations that allow NW Holdings a disproportionate influence over it. lnvestments in TWH and TWP are included in other investments on NW Holdings' balance sheet. lf this investment is not developed, then the maximum loss exposure related to TWH is limited to NW Holdings'equity investment balance, less its share of any cash or other assets available to NW Holdings as a 50% owner. The investment balance in TWH was $13.4 million at December 31, 2018 and 2017. lmpairment Analvsis lnvestments in nonconsolidated entities accounted for under the equity method are reviewed for impairment at each reporting period and following updates to our corporate planning assumptions. lf it is determined a loss in value is other than temporary, a charge is recognized for the difference between the investment's carrying value and its estimated fair value. Fair value is based on quoted market prices when available or on the present value of expected future cash flows. Differing assumptions could affect the timing and amount of a charge recorded in any period. ln 2011, TWP withdrew its original application with the FERC for a proposed natural gas pipeline in Oregon and informed FERC that it intended to re-file an application to reflect changes in the project scope aligning the project with the region's current and future gas infrastructure needs. TWP continues working with customers in the Pacific Northwest to further understand their gas transportation needs and determine the commercial support for a revised pipeline proposal. A new FERC certificate application is expected to be filed to reflect a revised scope based on these regional needs. NW Holdings' equity investment was not impaired at December 31 , 2018 as the fair value of expected cash flows from planned development exceeded NW Holdings' remaining equity investment of $13.4 million at December 31, 2018. However, if NW Holdings learns that the project is not viable or will not go forward, it could be required to recognize a maximum charge of up lo approximately $13.4 million based on the current amount of the equity investment, net of cash and working capital at TWP. NW Holdings will continue to monitor and update the impairment analysis as required. Exhibit 3 J. Palfreyman, Falls Water Co., lnc.

BUS,,VESS COMBINATIONS Falls Water On September 13, 2018, NWN Water, then a wholly-owned subsidiary of NW Nalural and now a wholly-owned subsidiary of NW Holdings, completed the acquisition of Falls Water Co., lnc. (Falls Water), a privately-owned water utility in the Pacific Norlhwest for preliminary non- cash consideration of $8.5 million, subject to closing adjustments, in the form of 125,000 shares of NW Natural common stock. Falls Water became a wholly-owned subsidiary of NWN Water and marked its first acquisition in the water services sector. This acquisition aligns with NW Holdings'water sector strategy as the acquisition provides NWN Water entry into ldaho, expands service area, and opens further opportunity for growth. Falls Water is based in ldaho Falls, ldaho and serves approximately 5,300 connections. Through the purchase of all of the outstanding shares of Falls Water, NWN Water acquired the net assets and 100% control of Falls Water. We determined that the Falls Water acquisition met the criteria of a business combination, and as such performed a preliminary allocation of the consideration to the acquired assets and assumed liabilities based on their fair value as of the acquisition date, the majority of which was allocated to goodwill. The allocation is considered preliminary as of December 31 , 2018, and is primarily associated with certain tax positions and goodwill. Subsequent adjustments are not expected to be significant, 1 5. DERIVATIVE INSTRUMENTS and any such adjustments are expected to be completed within a one- year measurement period. The acquisition costs were insignificant and were expensed as incurred. The results of Falls Water are not material to the consolidated financial results of NW Holdings. Preliminary goodwill of $6.4 million was recognized from this acquisition and is attributable to Falls Water's regulated service tenitory and experienced workforce as well as the strategic benefits expected from this high-growth service territory. NW Holdings has included this goodwill in other for segment reporting purposes, and it is not deductible for income tax purposes. No intangible assets aside from goodwill were acquired. See Note 2 for goodwill impairment information. Other Acquisitions During 2018, in addition to the Falls Water acquisition, NWN Water completed three acquisitions qualifying as business combinations. The aggregate fair value of the preliminary consideration transferred for these acquisitions was approximately $2.8 million. These business combinations, both individually and in aggregate, were not significant to NW Holdings' results of operations. As a result of all acquisitions completed, total goodwill was $9.0 million as of December 31, 201 8. NW Natural enters into financial derivative contracts to hedge a portion of the NGD segment's natural gas sales requirements. These contracts include swaps, options, and combinations of option contracts. These derivative financial instruments are primarily used to manage commodity price variability. A small portion of NW Natural's derivative hedging strategy involves foreign currency exchange contracts. NW Natural enters into these financial derivatives, up to prescribed limits, primarily to hedge price variability related to physical gas supply contracts as well as to hedge spot purchases of natural gas. The foreign currency forward contracts are used to hedge the fluctuation in foreign currency exchange rates for pipeline demand charges paid in Canadian dollars. ln the normal course of business, NW Natural also enters into indexed- price physical forward natural gas commodity purchase contracts and options to meet the requirements of NGD customers. These contracts qualify for regulatory deferral accounting treatment. NW Natural also enters into exchange contracts related to the third-party asset management of its gas portfolio, some of which are derivatives that do not qualify for hedge accounting or regulatory deferral, but are subject to NW Natural's regulatory sharing agreement. These derivatives are recognized in operating revenues, nel of amounts shared with NGD customers. Notional Amounts The following table presents the absolute notional amounts related to open positions on NW Natural derivative instruments: At December 31, ln thousands 2018 2017 Natural gas (in therms): Financial Physical Foreign exchange 408,850 472,275 $ 6,936 $ 429j00 520,268 7,669 105 Purchased Gas Adiustment (PGA) Derivatives entered into by NW Natural for the procurement or hedging of natural gas for future gas years generally receive regulatory deferral accounting treatment. ln general, commodity hedging for the current gas year is completed prior to the start of the gas year, and hedge prices are reflected in the weighted-average cost of gas in the PGA filing. Hedge contracts entered into after the start of the PGA period are subject to the PGA incentive sharing mechanism in Oregon. NW Natural entered the 2018-19 and 2017-18 gas yearwith forecasted sales volumes hedged at 48o/o and 49% in financial swap and option contracts, and 24o/o and 260/o in physical gas supplies, respectively. Hedge contracts entered into prior to the PGA filing, in September 2018, were included in the PGA for the 201 8-1 I gas year. Hedge contracts entered into after the PGA filing, and related to subsequent gas years, may be included in future PGA filings and qualify for regulatory deferral. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 1 13 of 210 Table of Contents Unrealized and Realized Gain/Loss The following table reflects the income statement presentation for the unrealized gains and losses from NW Natural's derivative instruments, which also represents all derivative instruments at NW Holdings: December31,2018 December 31, 2017 ln thousands Natural gas commodity Foreign exchange Natural gas commodity Foreign exchange Benefit (expense) to cost of gas Operating revenues Amounts deferred to regulatory accounts on balance sheet Total gain (loss) in pre-tax earnings UNREALIZED GAIN/LOSS. Outstanding derivative instruments related to regulated NGD operations are deferred in accordance with regulatory accounting standards. The cost offoreign currency forward and natural gas derivative contracts are recognized immediately in the cost of gas; however, costs above or below the amount embedded in the current year PGA are subject to a regulatory deferral tariff and therefore, are recorded as a regulatory asset or liability. REALIZED GAIN/LOSS. Net gains of $7.4 million and net losses of $7.8 million were realized for the years ended December 31, 2018 and 2017 respectively, from the settlement of natural gas financial derivative contracts. Realized gains and losses are recorded in cost ofgas, deferred through regulatory accounts, and amortized through customer rates in the following year. Credit Risk Management of Fi I Derivatives lnstruments No collateral was posted with or by NW Natural counterparties as of December 31, 2018 or 2017 . NW Natural attempts to minimize the potential exposure to collateral calls by counterparties to manage liquidity risk. Counterparties generally allow a certain credit limit threshold before requiring NW Natural to post collateral against loss positions. Given NW Natural's counterparty credit limits and portfolio diversification, it was not subject to collateral calls in 2018 or 2017.The collateral call exposure is set forth under credit support agreements, which generally contain credit limits. NW Natural could also be subject to collateral call exposure where it has agreed to provide adequate assurance, which is not specific as to the amount of credit limit allowed, but could potentially require additional collateral in the event of a material adverse change. Based on current commodity financial swap and option contracts outstanding, which reflect unrealized losses of $7.8 million at December 31, 2018, we have estimated the level of collateral demands, with and without potential adequate assurance calls, using current gas prices and various credit downgrade rating scenarios for NW Natural as follows: (211)26,665 210 $$(356) $ Credit Rating Downgrade Scenarios (Current ln thousands Ratings) A+/43 BBB+/Baa1 BBB/Baa2 BBB- /Baa3 $(1,23s) $ 1,660 (284) $(26,000) $ (1,o21) 107 (107)284 $ Specu- lative with Adequate Assurance Calls \Mthout Adequate Assurance Calls $$$$(3,940) $(6,059) 106 (3,e40) (4,452) NW Natural's financial derivative instruments are subject to master netting arrangements; however, they are presented on a gross basis in NW Natural's consolidated balance sheets. NW Natural and lts counterparties have the ability to seloff obligations to each other under specified circumstances. Such circumstances may include a defaulting party, a credit change due to a merger affecting either party, or any other termination event. lf netted by counterparty, NW Natural's derivative position would result in an asset of $3.6 million and a liability of $9.3 million as of December 31, 2018, and an asset of $2.9 million and a liability of $23.3 million as of December 31, 201 7. NW Natural is exposed to derivative credit and liquidity risk primarily through securing fixed price natural gas commodity swaps to hedge the risk of price increases for natural gas purchases made on behalf of customers. NW Natural utilizes master netting arrangements through lnternational Swaps and Derivatives Association contracts to minimize this risk along with collateral support agreements with counterparties based on their credit ratings. ln certain cases, NW Natural requires guarantees or letters of credit from counterparties to meet its minimum credit requirement standards. NW Natural's financial derivatives policy requires counterparties to have a certain investment{rade credit rating at the time the derivative instrument is entered into, and the policy specifies limits on the contract amount and duration based on each counterparty's credit rating. NW Natural does not speculate with derivatives; instead, derivatives are used to hedge exposure above risk tolerance limits. Any increase in market risk created by the use of derivatives should be offset by the exposures they modifo. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 114ot210 Table of Contents We actively monitor NW Natural's derivative credit exposure and place counterparties on hold for trading purposes or require other forms of credit assurance, such as letters of credit, cash collateral, or guarantees as circumstances warrant. The ongoing assessment of counterparty credit risk includes consideration of credit ratings, credit default swap spreads, bond market credit spreads, financial condition, government actions, and market news. A Monte-Carlo simulation model is used to estimate the change in credit and liquidity risk from the volatility of natural gas prices. The results of the model are used to establish earnings-a! risk trading limits. NW Natural's credit risk for all outstanding financial derivatives at December 31 , 2018 extends to October 31 ,2021 . We could become materially exposed to credit risk with one or more of our counterparties if natural gas prices experience a significant increase. lf a counterparty were to become insolvent or fail to perform on its obligations, we could suffer a material loss; however, we would expect such a loss to be eligible for regulatory deferral and rate recovery, subject to a prudence review. All of our existing counterparties currently have investment-grade credit ratings. 1 6. COMMITMENTS AND CO'VT"VGEA'C'ES Fair Value ln accordance with fair value accounting, non-performance risk is included in calculating fair value adjustments. This includes a credit risk adjustment based on the credit spreads of NW Natural's counterparties when it is in an unrealized gain position, or on NW Natural's own credit spread when it is in an unrealized loss position. The inputs in the valuation models include natural gas futures, volatility, credit default swap spreads, and interest rates. Additionally, the assessment of non- performance risk is generally derived from the credit default swap market and from bond market credit spreads. The impact of the credit risk adjustments for all outstanding derivatives was immaterial to the fair value calculation at December 31, 2018. As of December 31, 2018 and 2017, the net fair value was a liability of $5.7 million and a liability of $20.3 million, respectively, using significant other observable, or Level 2, inputs. No Level 3 inputs were used in the derivative valuations, and there were no transfers between Level 1 or Level 2 during the years ended December 31 , 201 8 and 2017 . 2019 2020 2021 2022 2023 Thereafter Total Leases Land, buildings, and equipment are leased under agreements that expire in various years, including a 99-year land lease that extends through 2108. Rental costs for continuing operations were $5.9 million, $7.3 million, and $5.9 million for the years ended December 31, 2018, 2017, and 2016, respectively, a portion of which was capitalized. The following table reflects NW Natural's future minimum lease payments due under non-cancelable operating leases for continuing operations at December 31 , 2O18. These commitments relate principally to the lease ofthe office headquarters and underground gas storage facilities. Minimum lease ln lhousands payments $ Additionally, the lease was analyzed under the lease standard in effect at the time of signing in consideration of build-to-suit lease accounting implications, and NW Natural concluded that it was the accounting owner of the asset during construction. As a result, NW Natural recognized $26.0 million and $0.5 million in property, plant and equipment and an obligation in other non-current liabilities for the same amount in its consolidated balance sheet at December 31 , 2018 and 2017, respectively. Gas Purchase and Pipeline Capacity Purchase and Release Commitments NW Natural has signed agreements providing for the reservation of firm pipeline capacity under which it is required to make fixed monthly payments for contracted capacity. The pricing component of the monthly payment is established, subject to change, by U.S. or Canadian regulatory bodies. ln addition, NW Natural has entered into long-term sale agreements to release firm pipeline capacity. NW Natural also enters into short{erm and long{erm gas purchase agreements. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page I 15 ol 210 5,368 4,812 7,077 I ,ZZC 7,304 '149,881 $181,665 ln October 2017, NW Natural entered into a 20-year operating lease agreement for a new headquarters in Portland, Oregon in anticipation of the expiration of the current lease in 2020. Payments under the new lease are expected to commence in 2020. Total estimated base rent payments over the life of the lease are approximately $160 million and have been included in the table above. There is an option to extend the term of the lease for two additional seven-year periods. 107 Table of Contents The aggregate amounts of these agreements were as follows at December 3'l , 2018:Total payments for fixed charges under capacity purchase agreemenls were $82.6 million for2018, $85.3 million tor2017, and $85.0 million for 2016. lncluded in the amounts were reductions for capacity release sales of $4.3 million for 2018, $4.5 million tor 2017, and $4.5 million for 2016. ln addition, per-unit charges are required to be paid based on the actual quantities shipped under the agreements. ln certain take-or-pay purchase commitments, annual deficiencies may be offset by prepayments subject to recovery over a longer term if future purchases exceed the minimum annual requirements.

ENVIRONMENTAL MATTERS 923,434 201,224 183 NW Natural owns, or previously owned, properties that may require environmental remediation or action. The range of loss for environmental liabilities is estimated based on current remediation technology, enacted laws and regulations, industry experience gained at similar sites, and an assessment of the probable level of involvement and financial condition of other potentially responsible parties (PRPs). \lVhen amounts are prudently expended related to site remediation of those sites described herein, NW Natural has a recovery mechanism in place to collect 96.68% of remediation costs from Oregon customers, and NW Natural is allowed to defer environmental remediation costs allocated to customers in Washington annually until they are reviewed for prudence at a subsequent proceeding. These sites are subjecl lo the remediation process prescribed by the Environmental Protection Agency (EPA) and the Oregon Department of Environmental Quality (ODEQ). The process begins with a remedial investigation (Rl) to determine the nature and extent of contamination and then a risk assessment (RA) to establish whether the contamination at the site poses unacceptable risks to humans and the environment. Next, a feasibility study (FS) or an engineering evaluation/cost analysis (EE/CA) evaluates various remedial alternatives. lt is at this point in the process when NW Natural is able to estimate a range of remediation costs and record a reasonable potential remediation liability, or make an adjustment to the existing liability. From this study, the regulatory agency selects a remedy and issues a Record of Decision (ROD). After a ROD is issued, NW Natural would seek to negotiate a consent decree or consent judgment for designing and implementing the remedy. NW Natural would have the ability to further refine estimates of remediation liabilities at that time. Remediation may include treatment of contaminated media such as sediment, soil and groundwater, removal and disposal of media, institutional controls such as legal restrictions on future property use, or natural recovery. Following construction of the remedy, the EPA and ODEQ also have requirements for ongoing maintenance, monitoring, and other post-remediation care that may continue for many years. Where appropriate and reasonably known, NW Natural will provide for these costs in the remediation liabilities described below. Due to the numerous uncertainties surrounding the course of environmental remediation and the preliminary nature of several site investigations, in some cases, NW Natural may not be able to reasonably estimate the high end of the range of possible loss. ln those cases, the nature ofthe possible loss has been disclosed, as has the fact that the high end of the range cannot be reasonably estimated where a range of potential loss is available. Unless there is an estimate within the range of possible losses that is more likely than other cost estimates within that range, NW Natural records the liability at the low end of this range. lt is likely changes in these estimates and ranges will occur throughout the remediation process for each of these sites due to the continued evaluation and clarifi cation concerning responsibility, the complexity of environmental laws and regulations, and the determination by regulators of remediation alternatives. ln addition to remediation costs, NW Natural could also be subject to Natural Resource Damages (NRD) claims. NW Natural will assess the likelihood and probability of each claim and recognize a liability if deemed appropriate. Refer to " Othe r Portl a nd H a rbo /' below. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 116 of210 108 Table of Contents Environmenta! Sites The following table summarizes information regarding liabilities related to environmental sites, which are recorded in other current liabilities and other noncurrent liabilities in NW Natural's balance sheet at December 31: Current Liabilities Non-Current Liabilities ln thousands 2018 2017 2018 2017 Portland Harbor site: Gasco/Siltronic Sediments Other Portland Harbor Gasco/Siltronic U pland site Central Service Center site Front Street site Oregon Steel Mills Total PORTLAND HARBOR SITE. The Portland Harbor is an EPA listed Superfund site that is approximately 10 miles long on the Willamette River and is adjacent to NW Natural's Gasco uplands sites. NW Natural is one of over one hundred PRPs to the Superfund site. ln January 201 7, the EPA issued its Record of Decision, which selects the remedy for the clean-up of the Portland Harbor site (Portland Harbor ROD). The Portland Harbor ROD estimates the present value total cost at approximately $1.05 billion with an accuracy between -30% and +50% of actual costs. NW Natural's potential liability is a portion of the costs of the remedy for the entire Portland Harbor Superfund site. The cost of that remedy is expected to be allocated among more than 100 PRPs. ln addition, NW Natural is actively pursuing clarification and flexibility under the ROD in order to better understand its obligation under the clean-up. NW Natural is also participating in a non-binding allocation process with the other PRPs in an effort to resolve its potential liability. The Portland Harbor ROD does not provide any additional clarification around allocation of costs among PRPs and, as a result of the issuance of the Portland Harbor ROD, NW Natural has not modified any of the recorded liabilities at this time. NW Natural manages its liability related to the Superfund site as two distinct remediation projects, the Gasco/Siltronic Sediments and Other Portland Harbor projects. Gasco/Siltronic Sediments. ln 2009, NW Natural and Siltronic Corporation entered into a separate Administrative Order on Consent with the EPA to evaluate and design specific remedies for sediments adjacent to the Gasco uplands and Siltronic uplands sites. NW Natural submitted a draft EE/CA to the EPA inMay 2012 to provide the estimated cost of potential remedial alternatives for this site. At this time, the estimated costs for the various sediment remedy alternatives in the draft EE/CA, for the additional studies and design work needed before the cleanup can occur, and for regulatory oversight throughout the clean-up range from $49.5 million to $350 million. NW Natural has recorded a liability of $49.5 million for the sediment clean-up, which reflects the low end of the range. At this time, we believe 5,117 2,600 13,983 10 11,402 2,683 1,949 13,422 25 1,009 44,351 6,273 44,830 3 45,346 4,163 47,835 $ 179 10,757 179 33,112 $ 19,088 $ 95,636 $ 108,280 sediments at this site represent the largest portion of NW Natural's liability related to the Portland Harbor site discussed above. other Portland Harbor. \A/hile we believe liabilities associated with the Gasco/Siltronic sediments site represent NW Natural's largest exposure, there are other potential exposures associated with the Portland Harbor ROD, including NRD costs and harborwide clean-up costs (including downstream petroleum contamination), for which allocations among the PRPs have not yet been determined. NW Natural and other parties have signed a cooperative agreement with the Portland Harbor Natural Resource Trustee council to participate in a phased NRD assessment to estimate liabilities to support an early restoration-based settlement of NRD claims. One member of this Trustee council, the Yakama Nation, withdrew from the council in 2009, and in 2017 , filed suit against NW Natural and 29 other parties seeking remedial costs and NRD assessment costs associated with the Portland Harbor, set forth in the complaint. The complaint seeks recovery of alleged costs totaling $0.3 million in connection with the selection of a remedial action for the Portland Harbor as well as declaratory judgment for unspecified future remedial action costs and for costs to assess the injury, loss, or destruction of natural resources resulting from the release of hazardous substances at and from the Portland Harbor site. The Magistrate Judge has recommended granting NW Natural and certain other defendants' motion to stay the case. NW Nalural has recorded a liability for NRD claims which is at the low end of the range of the potential liability; the high end of the range cannot be reasonably estimated at this time. The NRD liability is not included in the aforementioned range of costs provided in the Portland Harbor ROD. GASCO UPLANDS SITE. A predecessor of NW Natural, Portland Gas and Coke Company, owned a former gas manufacturing plant that was closed in 1958 (Gasco site) and is adjacent to the Portland Harbor site described above. The Gasco site has been under investigation by NW Natural for environmental contamination under the ODEQ Voluntary Clean-Up Program (VCP). lt is not included in the range of remedial costs for the Portland Harbor site noted Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 1 17 of210 109 $ Table of Contents above. The Gasco site is managed in two parts, the uplands portion and the groundwater source control action. NW Natural submitted a revised Remedial lnvestigation Report for the uplands to ODEQ in May 2007 . ln March 2015, ODEQ approved the RA, enabling commencement of work on the FS in 2016. NW Natural has recognized a liability for the remediation of the uplands portion of the site which is at the low end of the range of potential liability; the high end of the range cannot be reasonably estimated at this time. ln October 2016, ODEQ and NW Natural agreed to amend their VCP agreement to incorporate a portion of the Siltronic property adjacent to the Gasco site formerly owned by Portland Gas & Coke between 1939 and 1960 into the Gasco RA and FS, excluding the uplands for Siltronic. Previously, NW Natural was conducting an investigation of manufactured gas plant constituents on the entire Siltronic uplands for ODEQ. Siltronic will be working with ODEQ directly on environmental impacts to the remainder of its property. ln September 2013, NW Natural completed construction of a groundwater source control system, including a water treatment station, at the Gasco site. NW Natural has estimated the cosl associated with the ongoing operation of the system and has recognized a liability which is at the low end of the range of potential costs. NW Natural cannot estimate the high end of the range at this time due to the uncertainty associated with the duration of the operation of the water treatment station, which is highly dependent on the remedy determined for both the upland portion as well as the final remedy for Gasco sediment exposure. OTHER SITES. ln addition to those sites above, NW Natural has environmental exposures at three other sites: Central Service Center, Front Street, and Oregon Steel Mills. NW Natural may have exposure at other sites that have not been identified at this time. Due to the uncertainty of the design of remediation, regulation, timing of the remediation, and in the case of the Oregon Steel Mills site, pending litigation, liabilities for each of these sites have been recognized at their respective low end of the range of potential liability; the high end of the range cannot be reasonably estimated at this time. central Service center site. NW Natural is currently performing an environmental investigation of the property under ODEQ's lndependent Cleanup Pathway. This site is on ODEQ's list of sites with confirmed releases of hazardous substances, and cleanup is necessary. Front Street site. The Front Street site was the former location of a gas manufacturing plant NW Natural operated (the former Portland Gas Manufacturing site, or PGM). At ODEQ's request, NW Natural conducted a sediment and source control investigation and provided findings to ODEQ. ln December 2015, a FS on the former Portland Gas Manufacturing site was completed. ln July 2017, ODEQ issued the PGM ROD. The ROD specifies the selected remedy, which requires a combination of dredging, capping trealment, and natural recovery. ln addition, the selected remedy also requires institutional controls and long{erm inspection and maintenance. NW Natural revised the liability in the second quarter of 201 7 to incorporate the estimated undiscounted cost of approximately $10.5 million for the selected remedy. Further, NW Natural has recognized an additional liability of $0.9 million for additional studies and design costs as well as regulatory oversight throughout the clean-up. NW Natural plans to complete the remedial design in early 201 9 and expects to construct the remedy during 201 9. oregon Steel Mills site. Refer to the "Legal Proceedings," below. Site Remediation and Recoverv Mechanism (SRRM) NW Natural has an SRRM through which it tracks and has the ability to recover past deferred and fulure prudently incurred environmenlal remediation costs allocable to Oregon, subject to an earnings test, for those sites identified therein. ln the February 20't 5 Order establishing the SRRM (2015 Order), the OPUC addressed outstanding issues related to the SRRM, which required NW Natural to forego the collection of $1 5 million out of approximately $95 million in total environmental remediation expenses and associated carrying costs. As a follow-up to the 2015 Order, the OPUC issued an additional Order in January 20'16 (20'16 Order) regarding the SRRM implementation in which the OPUC: (1) disallowed the recovery of $2.8 million of interest earned on the previously disallowed environmental expenditure amounts; (2) clarified the state allocation of 96.68% of environmental remediation costs for all environmental sites allocable to Oregon; and (3) confirmed NW Natural's treatment of $13.8 million of expenses put into the SRRM amortization account was correct and in compliance with prior OPUC orders. As a result of the 2016 Order, NW Natural recognized a $3.3 million non-cash charge in the first quarler, of which $2.8 million is reflected in other income and expense, net and $0.5 million is included in operations and maintenance expense. COLLECTIONS FROM OREGON CUSTOMERS. Under the SRRM collection process there are three types of deferred environmental remediation expense:. Pre-review - This class of costs represents remediation spend that has not yet been deemed prudent by the OPUC. Carrying costs on these remediation expenses are recorded at NW Natural's authorized cost of capital. NW Natural anticipates the prudence review for annual costs and approval ofthe earnings test prescribed by the OPUC to occur by the third quarter of the following year.. Poslreview - This class of costs represents remediation spend that has been deemed prudent and allowed after applying the earnings test, but is not yet included in amortization. NW Natural earns a carrying cost on these amounts at a rate equal to the five-year treasury rate plus 100 basis points.. Amortization - This class of costs represents amounts included in current customer rates for collection and is generally calculated as one-fifth of the poslreview deferred balance. NW Natural earns a carrying cost equal to the amortization rate determined annually by the OPUC, which approximates a short-term borrowing rate. Exhibit 3 J. Palfreyman, Falls Water Co., lnc.

As NW Natural collects amounts from customers, it recognizes these collections as revenue and separately amortizes an equal and offsetting amount of its deferred regulatory asset balance through the environmental remediation operating expense line shown separately in the operaling expense section of the income statement. NW Natural received total environmental insurance proceeds of approximately $150.0 million as a result of settlements from litigation that was dismissed in July 2014. Under the 201 5 OPUC Order, one-third of the Oregon allocated proceeds were applied to costs deferred through 2012wilh the remaining two-thirds applied to costs at a rate of $5.0 million per year plus interest over the following 20 years. NW Natural accrues interest on the insurance proceeds in the customer's favor at a rate equal to the five-year treasury rate plus 1 00 basis points. As of December 31, 2018, NW Natural has applied $73.2 million of insurance proceeds to prudently incurred remediation costs allocated to Oregon. The following table presents information regarding the total regulatory asset deferred as of December 31: ln thousands 2018 2017 $5.0 million tariff rider and $5.0 million insurance proceeds are recoverable through the SRRM. To the extent NW Natural earns more than its authorized ROE in a year, it is required to cover environmental expenses and interest on expenses greater than the $10.0 million with those earnings that exceed its authorized ROE. Under the 2015 Order, the OPUC stated they would revisit the deferral and amortization of future remediation expenses, as well as the treatment of remaining insurance proceeds three years from the original Order, or earlier if NW Natural gains greater certainty about its future remediation costs, to consider whether adjustments to the mechanism may be appropriate. NW Natural filed an update with the OPUC in March 2018 and recommended no changes. WASHINGTON DEFERRAL. ln Washington, cost recovery and carrying charges on amounts deferred for costs associated with services provided to Washington customers will be determined in a future proceeding. Legal Proceedings NW Holdings is not currently party to any direct claims or litigation, though in the future it may be subject to claims and litigation arising in the ordinary course of business. NW Natural is subject to claims and litigation arising in the ordinary course of business. Although the final outcome of any of these legal proceedings cannot be predicted with certainty, including the matter described below, NW Natural and NW Holdings do not expect that the ultimate disposition of any of these matters will have a material effect on financial condition, results of operations, or cash flows. OREGON STEEL MILLS SITE. ln 2004, NW Natural was served with a third-party complaint by the Port of Portland (the Port) in a Multnomah County Circuit Courl case, Oregon Steel Mills, lnc. v. The Port of Portland. The Port alleges that in the 1940s and 1 950s petroleum wastes generated by NW Natural's predecessor, Portland Gas & Coke Company, and 10 other third-party defendants, were disposed of in a waste oil disposal facility operated by the United States or Shaver Transportation Company on property then owned by the Port and now owned by Evraz Oregon Steel Mills. The complaint seeks contribution for unspecified past remedial action costs incurred by the Port regarding the former waste oil disposal facility as well as a declaratory judgment allocating liability for future remedial action costs. No date has been set for trial. ln August 2017, the case was stayed pending outcome of the Portland Harbor allocation process or other mediation. Although the final outcome of this proceeding cannot be predicted with certainty, NW Natural and NW Holdings do not expect the ultimate disposition of this matterwill have a material effect on NW Natural's or NW Holdings' financial condition, results of operations, or cash flows.

Environmental costs relate to specific sites approved for regulatory defenal by the OPUC and WUTC. ln Oregon, NW Natural earns a carrying charge on cash amounts paid, whereas amounts accrued but not yet paid do not eam a carrying charge until expended. NW Natural also accrues a carrying charge on insurance proceeds for amounts owed to customers. ln Washington, a carrying charge related to deferred amounts will be determined in a future proceeding. Current environmental costs represent remediation msts management expects to collect from customers in the next 12 months. Amounts included in this estimate are still subject to a prudence and eamings test review by the OPUC and do not include the $5.0 million tariff rider. The amounts allocable to Oregon are recoverable through NGD rates, sub.lect to an earnings test. t2) ENVIRONMENTAL EARNINGS TEST.

DISCO NTIN U ED OPERATION S NW Holdinos On June 20,2018, NWN Gas Storage, then a wholly-owned subsidiary of NW Natural, entered into a Purchase and Sale Agreement (the Agreement) that provides for the sale by NWN Gas Storage of all of the membership interests in Gill Ranch. Gill Ranch owns a 75% interest in the natural gas storage facility located near Fresno, California known as the Gill Ranch Gas Storage Facility. PG&E owns the remaining 25% interest in the Gill Ranch Gas Storage Facility. The CPUC regulates Gill Ranch under a market-based rate model which allows for the price of storage services to be set by the marketplace. The CPUC also regulates the issuance of securities, system of accounts, and regulates intrastate storage services. The Agreement provides for an initial cash purchase price of $25.0 million (subject to a working capital adjustment), plus potential additional payments to NWN Gas Storage of up to $26.5 million in the aggregate if Gill Ranch achieves certain economic performance levels for the first three full gas storage years (April 1 of one year through March 3't of the following year) occurring after the closing and the remaining portion of the gas storage year during which the closing occurs. We expect the transaction to close in 2019. The closing of the transaction is subject to approval by the CPUC, satisfaction of representations, warranties and covenants of the Agreement, and other customary closing conditions. ln July 2018, Gill Ranch filed an application with the CPUC for approval of this transaction. On February 14,2019, the active parties to the CPUC proceeding filed a settlement agreement with the CPUC. The CPUC is expected to rule on the settlement agreement within 90 days of its filing, but may grant further time for public comment. We expect an order on this matter by the end of June. As a result of the strategic shift away from the California gas storage market and the significance of Gill Ranch's financial results in 2017, we concluded that the pending sale of Gill Ranch qualified it as assets and liabilities held for sale and discontinued operations. As such, the assets and liabilities associated with Gill Ranch have been classified as discontinued operations assets and discontinued operations liabilities, respectively, and, the results of Gill Ranch are presented, net of tax, as discontinued operations separate from the results of continuing operations for all periods presented. The expenses included in the results ofdiscontinued operations are the direct operating expenses incurred by Gill Ranch that may be reasonably segregated from the cosls of our continuing operations. The following table presents the carrying amounts of the major components of Gill Ranch that are classified as discontinued operations assets and liabilities on NW Holdings'consolidated balance sheets: NW Holdings Discontinued Operations ln thousands 2018 2017 Assets: Accounts receivable lnventones Other current assets Property, plant, and equipment Less: Accumulated depreciation Other non-current assets Discontinued operations - current assets Discontinued operations - non-current assets Total discontinued operations assets '13,269 3,057 10,817 $ 13,269 $ 13,874 $390 $ 685 333 11,621 7 247 2,126 396 535 10,816 Liabilities: Accounts payable Other cunent liabilities Other non-current liabilities Discontinued operations - current liabilities Discontinued operations - non-current liabilities Total discontinued operations liabilities $aaa a 307 11,779 1,287 306 12,043 112 12,959 1,593 12,043 $ 12,959 $ 13,636 The total assets and liabilities of Gill Ranch are classified as current as of December 31, 2018 because it is probable that the sale will be completed within one year.

On February 27,2019,the Organization and Executive Compensation Committee (the "Committee") of the Company's Board of Directors (the "Board") awarded restricted stock units to Recipient pursuant to Section 6 of the Company's Long Term Incentive Plan (the "Plan"). Recipient desires to accept the award subject to the terms and conditions of this Agreement. NOW, THEREFORE, the parties agree as follows: I . Grant of Restricted Stock Units: Dividend Equivalents. Subject to the terms and conditions of this Agreement, the Company hereby grants to the Recipient restricted stock units (the "RSUs"). The grant of RSUs obligates the Company, upon vesting in accordance with this Agreement, to deliver to the Recipient one share of Common Stock of the Company (a "Share") for each RSU. Upon vesting of each RSU, the Company also agrees to make a dividend equivalent cash payment with respect to each vested RSU in an amount equal to the total amount of dividends paid per share of Company Common Stock for which the dividend record dates occurred after the date of this Agreement and before the date of delivery of the underlying Shares. The RSUs are subject to forfeiture as set forth in Sections 2.1 and 2.10 below. 2. Vestine; Forfeiture Restriqliqn. 2.1 Vestine Schedule. (a) All of the RSUs shall initially be unvested. Subject to Sections 2.3,2.4,2.5,2.10 and 5.2, the RSUs shall vest as follows: (l) one-fourth of the RSUs shall vest on March l, 2020 if the Performance Threshold (as defined in Section 2.2 below) is satisfied for 2019; (2) an additional one-fourth of the RSUs shall vest on March 1,2021if the Performance Threshold is satisfied for2020; (3) an additional one-fourth of the RSUs shall vest on March 1,2022 if the Performance Threshold is satisfied for 2021; and (4) the finalone-fourth of the RSUs shallvest on March l, 2023 if the Performance Threshold is satisfied for2022. (b) If the Performance Threshold is not satisfied for any year set forth in ( I ), (2), (3) or (a) above, the RSUs that would have vested if the Performance Threshold had been satisfied for that year (the "Performance Year") shall be forfeited to the Company effective as of the last day of the Performance Year. For example, if the Performance Threshold is not Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page'148 of 210 satisfied for 2019, all RSUs that were scheduled to vest on March 1,2020 shall be forfeited effective as of December 31,2019 (c) If a Change in Control (as defined in Section 2.6 below) occurs, the Performance Threshold shall be deemed to be satisfied for all Performance Years that were not completed prior to the Change in Control, with the effect that the RSUs outstanding at the time of the Change of Control shall vest upon completion of the applicable time periods in Section 2.1(a). 2.2 Performance Threshold. (a) For purposes of this Agreement, the "Performance Threshold" for any year shall be satisfied if the ROE (as defined below) for that year is greater than the 5 Yr Avg Cost of LT Debt (as defined below) for that year. (b) The "ROE" for any year shall be calculated by dividing the Company's Adjusted Net Income (as defined below) for the year by the Average Equity (as defined below) for the year. Subject to adjustment in accordance with Section 2.2(c) below, the Company's "Adjusted Net Income" for any year shall be equal to the Company's net income attributable to common shareholders for the year, as set forth in the audited consolidated statement of income of the Company and its subsidiaries for the year. Subject to adjustment in accordance with Section 2.2(c) below, "Average Equity" for any year shall mean the average of the Company's total common stock equity as of the last day of the year and the Company's total common stock equity as of the last day of the prior year, in each case as set forth on the audited consolidated balance sheet ofthe Company and its subsidiaries as ofthe applicable date. (c) The Committee may, at any time, approve adjustments to the calculation of ROE to take into account such unanticipated circumstances or significant, non-recuning or unplanned events as the Committee may determine in its sole discretion, and such adjustments may increase or decrease ROE. Possible circumstances that may be the basis for adjustments shall include, but not be limited to, any change in applicable accounting rules or principles; any gain or loss on the disposition of a business; impairment of assets; dilution caused by Board approved business acquisition; tax changes and tax impacts ofother changes; changes in applicable laws and regulations; changes in rate case timing; changes in the Company's structure; and any other circumstances outside of management's control. (d) The "5 Yr Avg Cost of LT Debt" for any year shall mean the average of five numbers consisting of the Avg Cost ofLT Debt (as defined below) for that year and for each ofthe four preceding years. The "Avg Cost ofLT Debt" for any year shall be equal to the sum of the Weighted Costs (as defined below) calculated for each series or tranche of long-term debt of the Company outstanding on the last day of the year. The "Weighted Cost" for a series or tranche of long-term debt as of any date shall be calculated by multiplying the Effective Interest Rate (as defined below) on the debt as of that date by the outstanding principal balance of the debt on that date, and then dividing the resulting amount by the Company's total outstanding principal balance oflong-term debt as ofthat date. The "Effective Interest Rate" for a series or tranche oflong-term debt as ofany date shall be the yield calculated based on the Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 149 of 210 2 settlement date for the original issuance ofthe series or tranche, the maturity date ofthe series or tranche, the stated annual interest rate of the series or tranche in effect on that date, the number of interest payments per year under the terms ofthe series or tranche, the initial borrowing ofan amount equal to the principal balance net ofDebt Issuance Costs (as defined below) forthe series ortranche, and the repayment of principal at maturity or otherwise according to the terms of the series or tranche. The "Debt Issuance Costs" for a series or tranche oflong-term debt shall include the fees, commissions and expenses ofissuance ofsuch debt, any other purchase discount from the face amount of such debt, and any premiums, write-offs of unamortized debt issuance costs and other costs incuned in connection with retiring debt refinanced with the proceeds ofsuch debt, all as reflected in the Company's accounting records. For purposes ofthis Section 2.2(d), the Company's long term debt and the interest rates and outstanding principal balances ofthe outstanding series or tranches of long-term debt as of any date shall be those amounts as set forth in the audited consolidated financial statements of the Company and its subsidiaries for the year ending on that date, and shall in all cases include the cunent portion ofany long-term debt and exclude bonowings under a revolving credit facility. For the avoidance of doubt, the Effective Interest Rate for purposes of this Agreement of each series of fixed-rate long-term debt outstanding as of the date of this Agreement is set forth on Exhibit A hereto. 2.3 Effect of Retirement. Death. or Disability (a) If Recipient's employment by the Company or any parent or subsidiary of the Company (the "Employer") terminates because of Retirement (as defined below), death or physical disability (within the meaning of Section 22(e)(3) of the Code and a Change in Control has not previously occuned, all outstanding RSUs shall remain outstanding and subject to potential future vesting upon satisfaction ofthe Performance Threshold for the applicable years.

Certification and Delivery. As soon as practicable following the completion of each Performance Year, the Company shall calculate the ROE and the 5 Yr Avg Cost of LT Debt for that Performance Year, and shall submit those calculations to the Committee. At or prior to the regularly scheduled meeting of the Committee held in February of the year immediately following each Performance Year (each, a "Certification Meeting"), the Committee shall certify in writing (which may consist of approved minutes of the meeting) whether or not the Performance Threshold was satisfied for that Performance Year. Unless otherwise required under this Agreement as a result of the occunence of a Change in Control, no amounts shall be delivered or paid unless the Committee certifies that the Performance Threshold has been satisfied for the applicable Performance Year. Subject to applicable tax withholding, on a date (a Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 153 of210 6 "Payment Date") that is on or as soon as practicable after the date any of the RSUs become vested or, if later, five business days following the Certification Meeting relating to those RSUs, the Company shall deliver to Recipient (a) the number of Shares underlying the RSUs that vested (rounded down to the nearest whole share), and (b) the dividend equivalent cash payment determined under Section I with respect to the number of Shares that are delivered; provided, however, that if accelerated vesting of the RSUs occurs pursuant to Section 2.3(b) as a result of Recipient's Retirement after a Change in Control has previously occuned, the Payment Date shall be delayed until a date that is on or as soon as practicable after the earlier of(x) the date the RSUs would have vested under Section 2.1, or (y) the date that is six months after Recipient's separation from service (within the meaning of Section 4094 of the Internal Revenue Code). Notwithstanding the foregoing provisions of this Section 3, if Recipient shall have made a valid election to defer receipt of the Shares and dividend equivalent cash payment pursuant to the terms of Northwest Natural's Deferred Compensation Plan for Directors and Executives (the "DCP"), payment of RSUs that vest shall be made in accordance with that election. 4. Tax Withholdine. 4.1 Recipient acknowledges that, on any Payment Date when Shares are delivered to Recipient, the Value (as defined below) on that date of the Shares so delivered (as well as the amount of the related dividend equivalent cash payment) will be treated as ordinary compensation income for federal and state income and FICA tax purposes, and that the Employer will be required to withhold taxes on these income amounts. To satisfr the required withholding amount, the Employer shall first withhold all or part of the dividend equivalent cash payment, and if that is insufficient, the Employer shall withhold the number of Shares having a Value equal to the remaining withholding amount. For purposes of this Section 4, the "Value" of a Share shall be equal to the closing market price for Company Common Stock on the last trading day preceding the Payment Date. 4.2 Recipient acknowledges that under current tax law, the Employer is required to withhold FICA taxes with respect to the RSUs at the earlier of (a) the issuance of shares underlying the RSUs or (b) the date after a Change in Control on which Recipient becomes eligible for Retirement (or the date of the Change in Control if Recipient is eligible for Retirement at the time of the Change in Control). To satisfy the required minimum FICA withholding in the event that subsection (b) applies, Recipient shall, immediately upon notification of the amount due, pay to the Company in cash or by check amounts necessary to satisfr applicable FICA withholding requirements. If Recipient fails to pay the amount demanded, the Company may withhold that amount from other amounts payable to Recipient, including salary, subject to applicable law. 4.3 Notwithstanding the foregoing, Recipient may elect not to have Shares withheld to cover taxes by giving notice to the Company in writing prior to the Payment Date, in which case the Shares shall be issued or acquired in Recipient's name on the Payment Date thereby triggering the tax consequences, but the Company shall retain the certificate for the Shares as security until Recipient shall have paid to the Company in cash any required tax withholding not covered by withholding of the dividend equivalent cash payment. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 154 of21O 7 5. Sale of the Company. If there shall occur a merger" consolidation or plan of exchange involving the Company pursuant to which the outstanding shares of Common Stock of the Company are convefted into cash or other stock, securities or property, or a sale, lease, exchange or other transfer (in one transaction or a series ofrelated transactions) ofall, or substantially all, the assets ofthe Company, then either: 5. I the unvested RSUs shall be converted into restricted stock units for stock of the surviving or acquiring corporation in the applicable transaction, with the amount and type of shares subject thereto to be conclusively determined by the Committee, taking into account the relative values ofthe companies involved in the applicable transaction and the exchange rate, ifany, used in determining shares of the surviving corporation to be held by the former holders of the Company's Common Stock following the applicable transaction, and disregarding fractional shares; or 5.2 all of the unvested RSUs shall immediately vest and the underlying Shares and related dividend equivalent cash payment shall be delivered simultaneously with the closing of the applicable transaction such that Recipient will participate as a shareholder in receiving proceeds from such transaction with respect to those Shares. 6. Chanses in Capital Structure. If, prior to the full vesting of all of the RSUs granted under this Agreement, the outstanding Common Stock of the Company is increased or decreased or changed into or exchanged for a different number or kind of shares or other securities of the Company by reason of any stock split, combination of shares or dividend payable in shares, recapitalization or reclassification, appropriate adjustment shall be made by the Committee in the number and kind of shares subject to the unvested RSUs so that Recipient's proportionate interest before and afterthe occurrence of the event is maintained. Notwithstanding the foregoing, the Committee shall have no obligation to effect any adjustment that would or might result in the issuance of fractional shares, and any fractional shares resulting from any adjustment may be disregarded or provided for in any manner determined by the Committee. Any such adjustments made by the Committee shall be conclusive. 7. Recoupment On Misconduct. 7 .l If at any time before a Change in Control and within three years after any date on which any RSUs vested, (a) the Company's financial statements for the corresponding Performance Year are the subject of a restatement due to the Misconduct (as defined below) of any person (whether or not Recipient was personally involved in such Misconduct), and (b) based on the Company's financial statements as restated, the Performance Threshold was not satisfied for that Performance Year, then Recipient shall repay to the Company the Shares (the "Excess Shares") and dividend equivalent cash payment (the "Excess Dividends") that vested under this Agreement on that vesting date. If any Excess Shares are sold by Recipient prior to the Company's demand for repayment (including any shares withheld for taxes under Section 4 of this Agreement), Recipient shall repay to the Company 100% of the proceeds of such sale or sales. The Committee may, in its sole discretion, reduce the amount to be repaid by Recipient to take into account the tax consequences of such repayment for Recipient. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 155 of2lO 8 7.2 If the Committee determines that Recipient engaged in any Misconduct after the date of this Agreement and prior to a sale of any of the Shares (the "Tainted Shares"), and this determination is made before a Change in Control and within three years after the vesting of the Tainted Shares, Recipient shall repay to the Company the Excess Proceeds (as defined below). The Committee may, in its sole discretion, reduce the amount ofExcess Proceeds to be repaid by Recipient to take into account the tax consequences ofsuch repayment or any other factors. The retum ofExcess Proceeds is in addition to and separate from any other reliefavailable to the Company due to Recipient's Misconduct. 7 .3 "Misconduct" shall mean (a) willful commission of an act of fraud or dishonesty resulting in economic or financial injury to the Company, (b) willful misconduct that substantially impairs the Company's business or reputation, or (c) willful gross negligence in the performance of the person's duties; provided, however, that such acts shall only constitute Misconduct if the Committee determines that such acts contributed to an obligation to restate the Company's financial statements for any quarter or year or otherwise had (or will have when publicly disclosed) an adverse impact on the market price of the Company Common Stock. 7 .4 "Excess Proceeds" shall mean the excess of (a) the actual aggregate sales proceeds from Recipient's sales of Tainted Shares, over (b) the aggregate sales proceeds Recipient would have received from sales ofTainted Shares at a price per share determined appropriate by the Committee in its discretion to reflect what the market price of the Company Common Stock would have been if the restatement had occurred or other Misconduct had been disclosed prior to such sales. 7.5 If any portion of the Excess Shares and Excess Dividends was deferred under the DCP, that portion shall be recovered by canceling the amounts so deferred under the DCP and any dividends or other eamings credited under the DCP with respect to such cancelled amounts. The Company may seek direct repayment from Recipient of any Excess Shares, Excess Dividends and Excess Proceeds not so recovered and may, to the extent permitted by applicable law, offset such amounts against any compensation or other amounts owed by the Company to Recipient. In particular, such amounts may be recovered by offset against the after-tax proceeds of defened compensation payouts under the DCP, Northwest Natural's Executive Supplemental Retirement Income Plan or Northwest Natural's Supplemental Executive Retirement Plan at the times such deferred compensation payouts occur under the terms of those plans. Amounts that remain unpaid for more than 60 days after demand by the Company shall accrue interest at the rate used from time to time for crediting interest under the DCP. 8. Approvals. The obligations of the Company under this Agreement are subject to the approval of state and federal authorities or agencies with jurisdiction in the matter. The Company will use its best efforts to take steps required by state or federal law or applicable regulations, including rules and regulations of the Securities and Exchange Commission and any stock exchange on which the Company's shares may then be listed, in connection with the award under this Agreement. The foregoing notwithstanding, the Company shall not be obligated to issue or deliver Common Stock under this Agreement if such issuance or delivery would violate applicable state or federal law.

Any indemnification under Sections 3, 4, 5 or 6 of this Agreement shall be made no later than 90 days after receipt of the written request of lndemnitee for indemnification and shall not require that a determination be made in accordance with the Act by the persons specified in the Act that indemnification is required under this Agreement.

Palfreyman, Falls Water Co., lnc. Page 170 of21O 5 Agreement, but the burden of proving this defense shall be on the Company. Neither a failure of the Company (including its Board of Directors or its shareholders) to make a determination prior to the commencement of the enforcement action that indemnification of Indemnitee is proper in the circumstances, nor an actual determination by the Company (including its Board of Directors or its shareholders) that indemnification is improper shall be a defense to the action or create a presumption that Indemnitee is not entitled to indemnification under this Agreement or otherwise. The termination of any Proceeding by judgment, order of court, settlement, conviction or upon a plea of nolo-contendere, or its equivalent, shall not, of itself, create a presumption that Indemnitee is not entitled to indemnification under this Agreement or otherwise. I 2. Partial Indemnification. If Indemnitee is entitled under any provisions of this Agreement to indemnification by the Company for some or part of the Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by Indemnitee in the investigation, defense, appeal or settlement of any Proceeding but not, however, forthe total amount, the Company shall indemnify Indemnitee for the portion of the Expenses, judgments, fines and amounts paid in settlement to which Indemnitee is entitled. 13.

Palfreyman, Falls Water Co., lnc. Page 176 of210 J is against public policy and is, therefore, unenforceable and that claims for indemnification should be submitted to appropriate courts for adjudication); or (e) in connection with any Proceeding (or part of any Proceeding) initiated by Indemnitee, or any Proceeding by Indemnitee against the Company and its directors, officers, employees or other indemnitees, unless (i) the Company is expressly required by law to make the indemnification, (ii) the Proceeding was authorized by the Board of Directors of the Company, (iii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law, or (iv) Indemnitee initiated the Proceeding pursuant to Section I I of this Agreement and Indemnitee is successful in whole or in part in the Proceeding. 8.

Advances shall be made without regard to Indemnitee's ability to repay the expenses and without regard to Indemnitee's ultimate entitlement to indemnification under the other provisions of this Agreement. Advances made under this Section 8 shall be paid by the Company to Indemnitee as soon as practicable but in any event within thirty (30) business days after written request by Indemnitee to the Company pursuant to this Section 8. 9.

With respect to any Proceeding as to which Indemnitee notifies the Company of the commencement: (a) The Company will be entitled to participate in the Proceeding at its own expense. (b) Except as otherwise provided below, the Company may, at its option and jointly with any other indemnifying party similarly notified and electing to assume such defense, assume the defense ofthe Proceeding. rvith legal counsel reasonably satisfactory to the Indemnitee.

Palfreyman, Falls Water Co., lnc. Page 177 of 210 4 assumption of the defense, unless (i) lndemnitee reasonably concludes that there may be a conflict of interest between the Company and Indemnitee in the conduct ofthe defense ofthe Proceeding or (ii) the Company does not use legal counsel to assume the defense ofsuch Proceeding. The Company shall not be entitled to assume the defense of any Proceeding brought by or on behalf of the Company or as to which Indemnitee shall have made the conclusion provided for in (i) above. (c) If two or more persons who may be entitled to indemnification from the Company, including the Indemnitee, are parties to any Proceeding, the Company may require Indemnitee to use the same legal counsel as the other parties, Indemnitee shall have the right to use separate legal counsel in the Proceeding, but the Company shall not be liable to Indemnitee under this Agreement, including Section 8 above, forthe fees and expenses ofseparate legal counsel incurred after notice from the Company ofthe requirement to use the same legal counsel as the other parties, unless the Indemnitee reasonably concludes that there may be a conflict of interest between Indemnitee and any of the other parties required by the Company to be represented by the same legal counsel. (d) The Company shall not be liable to indemnifr Indemnitee under this Agreement for any amounts paid in settlement of any Proceeding effected without its written consent, which shall not be unreasonably withheld.

Procedure Upon Application for Indemnification. Any indemnification under Sections 3, 4, 5 or 6 of this Agreement shall be made no later than 90 days after receipt of the written request of Indemnitee for indemnification and shall not require that a determination be made in accordance with the Act by the persons specified in the Act that indemnification is required under this Agreement. However, unless it is ordered by a court in an enforcement action under Section I I of this Agreement, no such indemnification shall be made if a determination is made within such 90-day period by (a) the Board of Directors by a majority vote of a quorum consisting of directors who were not parties to the Proceeding, or (b) independent legal counsel in a written opinion (which counsel shall be appointed ifa quorum is not obtainable), that the Indemnitee is not entitled to indemnification under this Agreement. 1 l. Enforcement. Indemnitee may enforce any right to indemnification or advances granted by this Agreement to Indemnitee in any court of competent jurisdiction if (a) the Company denies the claim for indemnification or advances, in whole or in part, or (b) the Company does not dispose of the claim within 90 days of a written request for indemnification or advances. Indemnitee, in the enforcement action, if successful in whole or in part, shall be entitled to be paid also the expense of prosecuting the claim. It shallbe a defense to any such enforcement action (other than an action brought to enforce a claim for advancement ofExpenses pursuant to Section 8 above, if Indemnitee has tendered to the Company the required affirmation and undertaking) that Indemnitee is not entitled to indemnification under this 5 Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 178 of210 Agreement, but the burden of proving this defense shall be on the Company. Neither a failure of the Company (including its Board of Directors or its shareholders) to make a determination prior to the commencement of the enforcement action that indemnification of Indemnitee is proper in the circumstances, nor an actual determination by the Company (including its Board of Directors or its shareholders) that indemnification is improper shall be a defense to the action or create a presumption that Indemnitee is not entitled to indemnification under this Agreement or otherwise. The termination of any Proceeding by judgment, order of court, settlement, conviction or upon a plea of nolo-contendere, or its equivalent, shall not, of itself, create a presumption that Indemnitee is not entitled to indemnification under this Agreement or otherwise. 12. Partial Indemnification. If Indemnitee is entitled under any provisions of this Agreement to indemnification by the Company for some or part of the Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by Indemnitee in the investigation, defense, appeal or settlement of any Proceeding but not, however, for the total amount, the Company shall indemnify Indemnitee forthe portion of the Expenses, judgments, fines and amounts paid in settlement to which Indemnitee is entitled. 13. Nonexclusivity and Continuity of Rights. The indemnification provided by this Agreement shallnot be deemed exclusive of any other rights to which Indemnitee may be entitled under the Restated Arlicles, the Company's Bylaws, any other agreement, any vote of shareholders or directors, the Act, or otherwise, both as to action in Indemnitee's official capacity and as to action in another capacity while holding office. The indemnification under this Agreement shall continue as to Indemnitee even though Indemnitee ceases to be a director or officer and shall inure to the benefit ofthe heirs and personal representatives oflndemnitee. I 4. Business Combinations. If any person or group (as defined in Section I 3(dX3) of the Securities Exchange Act of 1934, as amended) acquires the legal right to elect a majority of the Board of Directors of the Company in a transaction or series of transactions that has not received the prior approval of the Board of Directors of the Company, the Company or its successor, as the case may be, shall, for a period of two years following the date that such legal right is acquired (the "Trigger Date"), maintain any and all directors and officers' liability insurance in effect prior to the Trigger Date that covers Indemnitee. 15. Severabilitv. If this Agreement orany portion of it is invalidated on any ground by any court of competent jurisdiction, the Company shall indemnify Indemnitee as to Expenses, judgments, fines and amounts paid in settlement with respect to any Proceeding to the full extent permitted by any applicable portion of this Agreement that is not invalidated or by any other applicable law or anangement. 16. Subrogation. ln the event of payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee. Indemnitee shallexecute all documents required and shalldo allacts that may be necessary to secure such rights and to enable the Company effectively to bring suit to enforce such rights. 17.

Palfreyman, Falls Water Co., lnc.

NORTHWEST NATURAL HOLDING COMPANY INDEMNITEE ByBy: Signature Signature Type or Print Name Type or Print Name Title Address @e4-Is-Iep) Section 6: EX-10.Q (EXHIBIT 10.Q) As amended effective October 1, 201 8 NORTHWEST NATURAL GAS COMPANY EXECUTIVE ANNUAL INCENTIVE PLAN This amended Executive Annual Incentive Plan (the "Plan") is executed by Northwest Natural Gas Company, an Oregon corporation (the "Company"), effective October 1,2018. Effective October 1,2018, the Company became a wholly-owned subsidiary of Northwest Natural Holding Company ("Parent") and holders of Company common stock became holders of Parent common stock ("Parent Common Stock"). PURPOSE OF PLAN The success ofthe Company is dependent upon its ability to attract and retain the services ofkey executives ofthe highest competence and to provide incentives for superior performance. The purpose of the plan is to advance the interests of the Company and its shareholders through an incentive compensation program that will attract and retain key executives and motivate them to achieve performance goals. PROGRAM TERM This Plan is an annual incentive plan and each new calendar year commences a new Program Term. Each Program Term will begin on January I and conclude on December 3 l. PARTICIPATION 8 All executive officers of Executive Compensation Plan. the company and any other highly compensated employees as designated by the CompangsSgryization and Commiffee (the "Committee") are eligible to receive awards $.4Um$V)rUn9F#Sfv:igltUa.l+t"ld Incentive Page 18'l of 210 At the beginning of each Program Term. the Committee shall determine eligibility for Awards and establish for each participant. the target incentive levelas a percentage of year-end annualized based salary ("Target Award"). This information will be set forth in Exhibit I of the Plan document for the Program Term. Each such participating employee shall be referred to as a "Participant." To be eligible for payout of an Award the Participant must have a minimum of three months of service during the Program Term. If the Participant is a new employee or is newly eligible to participate in the Plan, that Participant must be in an eligible position on or before September 30 of the Program Term and will receive a prorated Award. In addition, the Participant must be employed by the Company or Parent on December 3 I of the Program Term to be eligible for payout of the Award for the Program Term unless the Participant is eligible for a prorated Award as provided in the next sentence. Eligibility for a prorated Award occurs when a Participant has three or more I Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 182 of 210 months of participation in the Program Term but the Participant's employment is terminated prior to December 3l of the Program Term due to one of the following: Retirement (unless such Retirement results from a termination of the Participant's employment by the Company or Parent for Cause), disability and death. Prorated Awards will be determined by prorating the Participant's final Award by the number of days employed during the Program Term. "Retirement" shall mean termination of employment after Participant is (a) age 62 with at least five years of service as an employee of the Company and Parent, or (b) age 55 with age plus years of service (including fractions) as an employee of the Company and Parent totaling at least 70. "Cause" shall mean (a) the willful and continued failure by a Participant to perform substantially the Participant's assigned duties with the Company or Parent (other than any such failure resulting from incapacity due to physical or mental illness) after a demand for substantial performance is delivered to the Participant by the Company or Parent which specifically identifies the manner in which the Participant has not substantially performed such duties, (b) willful commission by a Participant of an act of fraud or dishonesty resulting in economic or financial injury to the Company or Parent, (c) willful misconduct by a Participant that substantially impairs the Company's or Parent's business or reputation, or (d) willful gross negligence by a Participant in the performance ofhis or her duties. In the event of a change in job position during the Program Term, the Committee may, in its discretion, increase or decrease the amount of a Participant's Award to reflect such change. INCENTIVE FORMULA The formula for calculating Awards for each Program Term is as follows: Target Award x [( P/IPF Factor Weight )l:Participant Award Company Performance X Factor (CPF) CPF Factor Weight Priority/lndividual Performance Factor X (rPF) +( COMPANY PERFORMANCE FACTOR The Company performance goals in the Plan are intended to align the interest of Participants with those of the shareholders. The goals and the formula for determining the Company Performance Factor will be established by the Committee at the start of each Program Term and set forth as Exhibit IL The Committee may, at any time, approve adjustments to the calculation of the results under any Company performance goal to take into account such unanticipated circumstances or significant, non-recurring or unplanned events as the Committee may determine in its sole discretion, and such adjustments may increase or decrease the results. Possible circumstances that may be the basis for adjustments shall include. but not be limited to, any change in applicable accounting rules or principles; any gain or loss on the disposition of a business; impairment of assets; dilution caused by acquiring a business; tax changes and tax impacts of other changes; changes in applicable laws Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 183 of210 2 ) and regulations; changes in rate case timing; changes in the Company's structure; and any other circumstances outside of management's control. PRIORITY/INDIVIDUAL PERFORMANCE FACTOR The P/IPF weight used in calculating the Priority/lndividual Performance Factor will be established for each Participant by the Committee at the beginning of the Program Term and set forth as part of Exhibit I. Also included in Exhibit I will be the CPF Factor Weight for the Company Performance Factor. Priority/lndividual goals for each Participant will be established at the beginning of each Program Term and performance against these goals willbe assessed by the Participant's superior and approved by the C.E.O. at the end of the Program Term. This assessment will result in a rating on a scale of 0% to 175%.This rating is called the Priority/lndividual Performance Factor. The Participant will not receive a payout under the Priority/lndividual Performance component of an Award if the Priority/lndividual Performance Factor is less than 50%. ADMINISTRATION Award payouts will be calculated and paid no later than the March l5 following the end of the Program Term. Award payouts are subject to tax withholding unless the Participant made a prior election to defer the Award payout under the terms of the Defened Compensation Plan for Directors and Executives ("DCP"). All Award payouts shall be audited by the Internal Audit department and approved by the Committee prior to payment. The Plan shall be administered by the Committee. The Committee shall have the exclusive authority and responsibility for all matters in connection with the operation and administration of the Plan. Decisions by the Committee shall be final and binding upon all parties affected by the Plan, including the beneficiaries ofParticipants. The Committee may rely on information and recommendations provided by management. The Committee may delegate to management the responsibility for decisions that it may make or actions that it may take under the terms of the Plan, subject to the Committee's reserved right to review such decisions or actions and modify them when necessary or appropriate under the circumstances. The Committee shall not allow any employee to obtain control over decisions or actions that affect that employee's Plan benefits. RECOUPMENT ON EARNINGS RESTATEMENT If at any time before a Change in Control and within three years after the payout of Awards for a Program Term, Parent's financial statements for that Program Term are the subject of a restatement due to the Misconduct of any person, each Participant who received an Award payout for that Program Term (whether or not such Participant was personally involved in such Misconduct) shall repay to the Company the Excess Bonus Compensation (as defined below). For purposes of the Plan, "Excess Bonus Compensation" for any Participant means the positive difference, if any, 3 Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 184 of210 between (i) the Participant's Award payout as originally calculated, and (ii) the Participant's Award payout as recalculated with the results for Company performance goals being based on Parent's financial statements as restated. Excess Bonus Compensation shall not include any amounts in respect of any individual performance goals or in respect of Company performance goals that are not measured in whole or in part on financial results reported in Parent's financial statements. The Committee may, in its sole discretion, reduce the amount of Excess Bonus Compensation to be repaid by any Participant to take into account the tax consequences of such repayment for the Participant. If any portion of an Award payout was deferred under the DCP, any Excess Bonus Compensation to be repaid with respect to that Award shall first be recovered by canceling all or a portion of the amount so deferred under the DCP and any interest credited under the DCP with respect to such cancelled amount. The Company may seek direct repayment from the Participant of any Excess Bonus Compensation not so recovered and may, to the extent permitted by applicable law, offset such Excess Bonus Compensation against any compensation or other amounts owed by the Company to the Participant. In particular, Excess Bonus Compensation may be recovered by offset against the after-tax proceeds of deferred compensation payouts under the DCP, the Company's Executive Supplemental Retirement Income Plan or the Company's Supplemental Executive Retirement Plan at the times such defened compensation payouts occur under the terms of those plans. Excess Bonus Compensation that remains unpaid for more than 60 days after demand by the Company shall accrue interest at the rate used from time to time for crediting interest under the DCP. "Misconduct" shall mean (a) willful commission by any person of an act of fraud or dishonesty or (b) willful gross negligence by any person in the performance of his or her duties. "Change in Control" shall mean the occunence of any of the following events: (a) The consummation of: (i) any consolidation, merger or plan of share exchange involving Parent (a "Merger") as a result of which the holders of outstanding securities of Parent ordinarily having the right to vote forthe election of directors ("Voting Securities") immediately priorto the Merger do not continue to hold at least 50% of the combined voting power of the outstanding Voting Securities of the surviving corporation or a parent corporation of the surviving corporation immediately after the Merger, disregarding any Voting Securities issued to or retained by such holders in respect of securities of any other party to the Merger; (ii) any consolidation, merger, plan of share exchange or other transaction involving the Company as a result of which Parent does not continue to hold, directly or indirectly. at least 50% of the outstanding securities of the Company ordinarily having the right to vote for the election ofdirectors; or (iii) any sale, lease, exchange or other transfer (in one transaction or a series of related transactions) of all, or substantially all, the assets of Parent or the Company; Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 185 of210 4 (b) At any time during a period of two consecutive years, individuals who at the beginning of such period constituted Parent's Board of Directors ("lncumbent Directors") shall cease for any reason to constitute at least a majority thereof; provided, however, that the term "lncumbent Director" shall also include each new director elected during such two-year period whose nomination or election was approved by two-thirds of the Incumbent Directors then in office; or (c) Any person (as such term is used in Section l4(d) of the Securities Exchange Act of 1934, other than Parent or any employee benefit plan sponsored by Parent) shall, as a result of a tender or exchange offer, open market purchases or privately negotiated purchases from anyone other than Parent, have become the beneficial owner (within the meaning of Rule l3d-3 under the Securities Exchange Act of 1934), directly or indirectly, of Voting Securities representing twenty percent (20%) or more of the combined voting power of the then outstanding Voting Securities.

(Back To Too) Section 7: EX-l0.SS (EXHIBIT 10.SS) ANI\UAL INCENTTVE PLAII NW Natural Gas Storage LLC ("companytt, or "the companytt) PURPOSE The purpose of the Annual Incentive Plan (AIP) is to recognize and reward Non-Bargaining Unit (NBU) employees who have performed well and contributed to successful company performance as measured by key performance indicators. PROGRAM TERM This Plan is an annual incentive plan and each new calendar year commences a new Program Term. Each Program Term will begin on January I and conclude on December 31. PARTICIPATION AIINBU regular employees of the company are eligible to participate in the Annuallncentive Plan. For all purposes of this AIP, a person who is an employee of Northwest Natural Gas Company (NW Natural) on full-time assignment to the company and designated by the Company Board of Directors (BOD) shall be considered to be a regular employee of the company during the period of that full-time assignment. In these situations, a designated participant in this AIP shall not be eligible for incentive compensation from NW Natural. NW Natural Oversight If the President of NWNGS is considered by NW Naturalto be an executive officer of NW Natural for purposes of public disclosure, any decision ofthe BOD under this AIP that affects an award to the President shall be subject to and conditioned upon the approval of that decision by the Board of Directors of NW Natural or as delegated by the Board of Directors of NW Naturalto the Organization and Executive Compensation Committee. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 190 of210 9 To be eligible for an award the Participant must have been employed by the company in an NBU role for at least one month during the Program Term. In addition, the Participant must be employed on the date of the plan payout to be eligible for any award for the Program Term unless the Participants' employment is terminated prior to the payout date of the Program Term due to one of the following: retirement(*), disability or death, Board approved exception due disposition of an affiliated business which results in the participant's termination of employment with NWNGS. Prorated awards will be determined by prorating the Participant's final award by the number of days employed during the Program Term. In the case of a Board approved exception due to disposition of an affiliated business occurring during the Program Term, the participant's prorated award will be based upon their target award and not actual Company performance for the Program Term. Such award will be paid within thirty (30) days following the completion of the transition period as defined by the Board. The disposition of Gill Ranch Storage qualifies as Board approved and the Board will define the end of the transition period. However, participating employees with Company approved Retention Agreements, will be eligible for prorated AIP awards consistent with such agreements. Employees who transfer to or from employment or full-time assignment to Northwest Natural or another subsidiary will be eligible for a prorated award based upon the number of days they were eligible to participate in the AIP. (*) Retirement is defined as a minimum of 5 years of service (with the company or with an affiliate company) and age and service equals 70. INCENTIVE TARGETS Target incentive award opportunities will be established by salary grade for each Plan Year and approved by the Board of Directors. The target incentive levels for each salary grade are shown in Exhibit I to the Plan document for the PIan Year. The target incentive opportunity is assigned by salary grade and calculated by multiplying the Target Incentive percentage times the following for each employee category: NBU Salary Paid/Exempt - Annual Base Salary as of December 3l" of the plan year NBU Hourly Paid/i.{on-Exempt - Actual eligible eamings. including regular pay" overtime pay. & lump sum merit payments INCENTIVE FORMULA The formula for calculating the incentive award for the Program Term is as follows: Participant Award = Target Award X (CPF X CPF Factor Weight) + (lPF X IPF Factor Weight)) COMPANY PERFORMANCE FACTOR (CPF) The company performance goals in the Plan are intended to align the interest of Participants with those of the company. The goals and the formula for determining the Company Performance Factor will be established by the NW Natural Gas Storage, tta="Un:Bifff Directors (the "Board of Directors") at the start of each Program Term and set forth as Exhibit tlg.qadffUlilti{,{lF4&qfV$gggdl, qnd.fo.rula are Page 191 of210 established for a Program Term, the Board of Directors retains discretion to modify the goals and formula, including adjusting the calculation of any financial or other goal to eliminate the effects of significant extraordinary, non-recurring or unplanned items. INDIVIDUAL PERFORMANCE FACTOR (IPF) The IPF weight used in calculating the Individual Performance Factor will be established for each Participant by the President, subject to the approval of the Board of Directors atthe beginning of the Program Term. Individualgoals foreach Participant willbe established by the Participant's leader (subject to the approval ofthe President, and for the President subject to the approval ofthe Board ofDirectors) at the beginning of each Program Term. Performance against these goals will be assessed by the Participant's leader at the end of the Program Term (subject to the approval of the President, and for the President subject to the approval of the Board of Directors). This assessment will result in a rating on a scale of 0 to 1.5 (the "lndividual Performance Factor"). The Participant will not receive an award if the Individual Performance Factor is less than 0.5. ADMINISTRATION Awards will be calculated and paid no later than March I 5 following the end of the Program Term. Awards are subject to tax withholding unless the Participant made a prior election to defer the Award under the terms of the NW Natural Gas Company Deferred Compensation Plan for Directors and Executives if they are eligible for this plan. All awards shall be audited and approved by the Board of Directors prior to payment. The Plan shall be administered by the Board of Directors. Except to the extent provided under 'NW Natural Oversight" above. The Board of Directors shall have the exclusive authority and responsibility for all matters in connection with the operation and administration of the Plan. Except to the extent provided under "NW Natural Oversight: above. Decisions by the Board of Directors shall be final and binding upon all parties affected by the Plan, including the beneficiaries ofParticipants. The Board of Directors may rely on information and recommendations provided by management. The Board of Directors may delegate to management the responsibility for decisions that it may make or actions that it may take under the terms of the Plan, subject to the Board ofDirectors reserved right to review such decisions or actions and modifo them when necessary or appropriate under the circumstances. The Board of Directors shall not allow any employee to obtain control over decisions or actions that affect that employee's Plan benefits. AMENDMENTS AND TERMINATION The Board of Directors has the power to terminate this Plan at any time or to amend this Plan at any time and in any manner that it may deem advisable. (Back To Top) Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 192 of 210 Section 8: EX-10.2 (E){H.IBIT l0.Z) PERFORMANCE SHARE LONG TERM INCENTIVE AGREEMENT This Agreement is entered into as of February _, 2019, between Northwest Natural Holding Company, an Oregon corporation (the "Company"), and ("Recipient"). On February _,2019, the Organization and Executive Compensation Committee (the "Committee") of the Company's Board of Directors (the "Board") authorized a performance-based stock award (the "Award") to Recipient pursuant to Section 6 of the Company's Long Term Incentive Plan (the "Plan"). Recipient desires to accept the Award subject to the terms and conditions of this Agreement. NOW, TIIEREFORE, the parties agree as follows: l. Award. Subject to the terms and conditions of this Agreement, the Company shall issue or otherwise deliver to the Recipient the number of shares of Common Stock of the Company (the "Performance Shares") determined under this Agreement based on (a) the performance of the Company during the three-year period from January 1,2019 to December 31,2021(the "Award Period") as described in Section 2 and (b) Recipient's continued employment during the Award Period as described in Section 3. If the Company issues or otherwise delivers Performance Shares to Recipient, the Company shall also pay to Recipient the amount of cash determined under Section 4 (the "Dividend Equivalent Cash Award"). Recipient's "Target Share Amount" for purposes of this Agreement is shares. 2. Performance Conditions. 2.1 Payout FactoI.Subject to possible reduction under Section 3, the number ofPerformance Shares to be issued or otherwise delivered to Recipient shall be determined by multiplying the Payout Factor (as defined below) by the Target Share Amount. The "Payout Factor" shall be equal to (a) the TSR Modifier as determined under Section 2.2, multiplied by (b) the EPS Payout Factor as determined under Section 2.3 below; provided, however, that the Payout Factor shall not be greater than200Yo and the Payout Factor shall be 0% if the ROIC Performance Threshold (as defined in Section 2.4 below) is not satisfied. Notwithstanding the foregoing, if a Change in Control (as defined in Section 3.7) occurs before the last day of the Award Period, the Payout Factor shall be 100%. 2.2 TSR Modifier (a) The "TSR Modifier" shall be determined under the table below based on the TSR Percentile Rank (as defined below) of the Company: TSR Percentile Rank TSR Modifier less than 25% 25o/o to 75Yo more than 75%o 75% 100% l25o/o (b) To determine the Company's "TSR Percentile Rank," the TSR of the Company and each of the Peer Group Companies (as defined below) shall be calculated, and 1 00 t7 4498.2 00s5570-00335 Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 193 of21O the Peer Group Companies shall be ranked based on their respective TSR's from lowest to highest. If the Company's TSR is equal to the TSR of any other Peer Group Company, the Company's TSR Percentile Rank shall be equal to the number of Peer Group Companies with a lower TSR divided by the number that is one less than the total number of Peer Group Companies, with the resulting amount expressed as a percentage and rounded to the nearest tenth ofa percentage point. Ifthe Company's TSR is between the TSRs ofany two Peer Group Companies, the TSR Percentile Ranks of those two Peer Group Companies shall be determined as set forth in the preceding sentence, and the Company's TSR Percentile Rank shall be interpolated as follows. The excess of the Company's TSR over the TSR of the lower Peer Group Company shall be divided by the excess of the TSR of the higher Peer Group Company over the TSR of the lower Peer Group Company. The resulting fraction shall be multiplied by the difference between the TSR Percentile Ranks of the two Peer Group Companies. The product of that calculation shall be added to the TSR Percentile Rank of the lower Peer Group Company, and the resulting sum (rounded to the nearest tenth of a percentage point) shall be the Company's TSR Percentile Rank. The intent of this definition of TSR Percentile Rank is to produce the same result as calculated using the PERCENTRANK function in Microsoft Excel to determine the rank of the Company's TSR within the array consisting of the TSRs of the Peer Group Companies. (c) The "Peer Group Companies" consist of those companies that were components of the Russell 2500 Utilities Index on October l, 201 8 and that continue to be components of the Russell 2500 Utilities Index through December 31, 2021. lf the Russell 2500 Utilities Index ceases to be published prior to December 31,2021, the Peer Group Companies shall consist of those companies that were components of the Russell 2500 Utilities Index on October 1,2018 and that continued to have publicly-traded common stock through December 31,2021. (d) The "TSR" for the Company and each Peer Group Company shall be calculated by (l) assuming that $100 is invested in the common stock of the company at a price equal to the average of the closing market prices of the stock for the period from October 1,2018 to December 31,2018, (2) assuming that for each dividend paid on the stock during the Award Period, the amount equal to the dividend paid on the assumed number of shares held is reinvested in additional shares at a price equal to the closing market price of the stock on the ex-dividend date for the dividend, and (3) determining the final dollar value of the total assumed number of shares based on the average of the closing market prices of the stock for the period from October I , 2021 to December 31, 2021 . The "TSR" shall then equal the amount determined by subtracting $ I 00 from the foregoing final dollar value, dividing the result by I 00 and expressing the resulting fraction as a percentage. (e) If during the Award Period any Peer Group Company enters into an agreement pursuant to which all or substantially all of the stock or assets of the Peer Group Company will be acquired by a third party (a "signed Acquisition"), and if the Signed Acquisition is not completed by the end of the Award Period, then that company shall not be a Peer Group Company. If a Signed Acquisition of a Peer Group Company is terminated (other than in connection with the execution of another Signed Acquisition) before the end of the Award Period, then that company shall remain a Peer Group Company, and the TSR for that Peer Group Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 194 of210 2 Company shall be calculated as provided in Section 2.2(d), except that if the announcement of the termination of the Signed Acquisition occurs during the last three months of the Award Period, for purposes of determining the final dollar value under clause (3) of Section 2.2 (d), the three-month period for which closing market prices are averaged shall be shortened to exclude any trading days preceding the announcement of the termination of the Signed Acquisition. 2.3 EPS Payout Factor. (a) The "EPS Payout Factor" shall be determined under the table below based on the Cumulative EPS Achievement Percentage (as defined below) achieved by the Company for the Award Period: Cumulative EPS Achievement Percentage EPS Payout Factor 0% 40% r00% 185% If the Company's Cumulative EPS Achievement Percentage is between any two data points set forth in the first column of the above table, the EPS Payout Factor shall be interpolated as follows. The excess of the Company's Cumulative EPS Achievement Percentage over the Cumulative EPS Achievement Percentage of the lower data point shall be divided by the excess of the Cumulative EPS Achievement Percentage of the higher data point over the Cumulative EPS Achievement Percentage of the lower data point. The resulting fraction shall be multiplied by the difference between the EPS Payout Factors in the above table corresponding to the two data points. The product of that calculation shall be rounded to the nearest hundredth ofa percentage point and then added to the EPS Payout Factor in the above table conesponding to the lower data point, and the resulting sum shall be the EPS Payout Factor. (b) The Company's "Cumulative EPS Achievement Percentage" for the Award Period shall equal the Cumulative EPS (as defined below) divided by the Cumulative EPS Target (as defined below), expressed as a percentage and rounded to the nearest tenth ofa percentage point. (c) The Company's "Cumulative EPS" for the Award Period shall equal the sum of the Company's diluted eamings per share of common stock ("EPS") for each of the three years in the Award Period. Subject to adjustment in accordance with Section 2.5 below, the Company's diluted eamings per share of common stock for any year shall be as set forth in the audited consolidated financial statements of the Company and its subsidiaries for that year. After giving effect to any adjustments required by Section 2.5,the EPS for each year shall be rounded to the nearest penny. (d) The Company's "Cumulative EPS Target" for the Award Period shall equal the sum of the EPS targets approved by the Committee for each of the three years in Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 195 of 210 J the Award Period. The EPS target for the first year of the Award Period as approved by the Committee is $_. Within the first 90 days of the second year of the Award Period, the Committee shall approve the EPS target for that year. Within the first 90 days of the third year of the Award Period, the Committee shall approve the EPS target for that year. 2.4 ROIC Performance Threshold. (a) For purposes of this Agreement, the "ROIC Performance Threshold" shall be satisfied if the Company's Average ROIC (as defined below) for the Award Period is greater than or equal to _%. (b) The Company's 'Average ROIC" for the Award Period shall equal the simple average of the Company's ROIC (as defined below) for each ofthe three years in the Award Period, rounded to the nearest hundredth ofa percentage point. The Company's "ROIC" for any year shall be calculated by dividing the Company's Adjusted Net Income (as defined below) for the year by the Company's Average Long Term Capital (as defined below) for the year, and rounding the result to the nearest hundredth of a percentage point. Subject to adjustment in accordance with Section 2.5 below, the Company's "Adjusted Net Income" for any year shall be equal to the Company's net income for the year, increased by the Company's interest expense, net for the year and reduced by the Company's interest income (including net interest on deferred regulatory accounts) for the year, in each case as set forth in the Company's Annual Report on Form l0-K for that year. "Average Long Term Capital" for any year shall mean the average of the Company's Long Term Capital (as defined below) as of the last day of the year and the Company's Long Term Capital as of the last day of the prior year. Subject to adjustment in accordance with Section 2.5 below, "Long Term Capital" as of any date shall equal the sum of the Company's total shareholders' equity as ofthat date and the Company's long-term debt (including current maturities) as ofthat date, in each case as set forth on the audited consolidated balance sheet ofthe Company as ofthat date. 2.5 EPS and ROIC Adiustments. The Committee may, at any time, approve adjustments to the calculation of Cumulative EPS and/or Average ROIC to take into account such unanticipated circumstances or significant, non-recurring or unplanned events as the Committee may determine in its sole discretion, and such adjustments may increase or decrease Cumulative EPS andlor Average ROIC. Possible circumstances that may be the basis for adjustments shall include, but not be limited to, any change in applicable accounting rules or principles; any gain or loss on the disposition of a business; impairment of assets; dilution caused by Board approved business acquisition; tax changes and tax impacts ofother changes; changes in applicable laws and regulations; changes in rate case timing; changes in the Company's structure; and any other circumstances outside of management's control. 3. Employment Condition. 3.1 Except as provided in Sections 3.2,3.3 or 7 .2, in order to receive a payout of Performance Shares, Recipient must be employed by the Company or any parent or subsidiary of the Company (the "Employer") on the last day of the Award Period. Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 196 of210 4 3.2 lf Recipient's employment by the Employer is terminated at any time prior to the end of the Award Period because of death, physical disability (within the meaning of Section 22(e)(3) of the Intemal Revenue Code of 1986 (the "Code")), or Retirement (unless such Retirement results from a termination of Recipient's employment by the Employer for Cause), Recipient shall be entitled to receive a pro-rated award. The number of Performance Shares to be issued or otherwise delivered as a pro-rated award under this Section 3.2 shall be determined by multiplying the number of Performance Shares determined under Section 2 by a fraction, the numerator of which is the number of days Recipient was employed by Employer during the Award Period and the denominator of which is the number of days in the Award Period. If Recipient's employment by the Employer terminates because of Retirement, death or physical disability and a Change in Control subsequently occurs before the end of the Award Period, the number of Performance Shares determined under Section 3.3 shall immediately be paid to Recipient. If a Change in Control occurs and Recipient's employment by the Employer subsequently terminates before the end of the Award Period because of Retirement, death or physical disability, the number of Performance Shares determined under Section 3.3 shall immediately be paid to Recipient. 3.3 CIC Acceleration. (a) If Recipient is a party to a Change in Control Severance Agreement with the Company or a parent or subsidiary of the Company, Recipient shall immediately be paid a pro-rated award if Recipient becomes entitled to a Change in Control Severance Benefit (as defined below). The number of Performance Shares to be issued or otherwise delivered as a pro-rated award under this Section 3.3 shall be determined by multiplying the Target Share Amount by a fraction, the numerator of which is the number of days Recipient was employed by the Employer during the Award Period and the denominator of which is the number of days in the Award Period. A "Change in Control Severance Benefit" means the severance benefit provided for in Recipient's Change in Control Severance Agreement with the Company or a parent or subsidiary of the Company; provided, however, that such severance benefit is a "Change in Control Severance Benefit" for purposes of this Agreement only if, under the terms of Recipient's Change in Control Severance Agreement, Recipient becomes entitled to the severance benefit (i) after a Change in Control of the Company has occurred, (ii) because Recipient's employment with the Employer has been terminated by Recipient for good reason in accordance with the terms and conditions of the Change in Control Severance Agreement or by the Employer other than for cause, and (iii) because Recipient has satisfied any other conditions or requirements specified in the Change in Control Severance Agreement and necessary for Recipient to become entitled to receive the severance benefit. For purposes ofthis Section 3.3(a), the terms "change in control," "good reason," "cause" and "disability" shall have the meanings set forth in Recipient's Change in Control Severance Agreement. (b) If Recipient is not a party to a Change in Control Severance Agreement with the Company or a parent or subsidiary of the Company, Recipient shall immediately be paid a pro-rated award in the amount stated in Section 3.3(a) if a Change in Control (as defined in Section 3.7 below) occurs and at any time after the earlier of Shareholder Approval (as defined in Section 3.8 below), if any, or the Change in Control and on or before the Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 197 of210 5 second anniversary of the Change in Control, (i) Recipient's employment is terminated by the Employer (or its successor) without Cause (as defined in Section 3.6 below), or (b) Recipient's employment is terminated by Recipient for Good Reason (as defined in Section 3.9 below). 3 .4 If Recipient's employment by the Employer is terminated at any time prior to the end of the Award Period and Section 3.2,3.3 or 7.2 does not apply to such termination, Recipient shall not be entitled to receive any Performance Shares. 3.5 "Retirement" shall mean termination of employment (a) on or after the first anniversary of the date of this Agreement, and (b) after Recipient is (l) age 62 with at least five years of service as an employee of the Company or a parent or subsidiary of the Company, or (2) age 60 with age plus years of service (including fractions) as an employee of the Company or a parent or subsidiary of the Company totaling at least 70. 3.6 "Cause" shall mean (a) the willful and continued failure by Recipient to perform substantially Recipient's assigned duties with the Employer (other than any such failure resulting from incapacity due to physical or mental illness) after a demand for substantial performance is delivered to Recipient by the Employer which specifically identifies the manner in which Recipient has not substantially performed such duties, (b) willfulcommission by Recipient of an act of fraud or dishonesty resulting in economic or financial injury to the Company or Employer, (c) willful misconduct by Recipient that substantially impairs the business or reputation of the Company or Employer, or (d) willful gross negligence by Recipient in the performance of his or her duties. 3.7 For purposes of this Agreement, a "Change in Control" of the Company shall mean the occurrence of any of the following events: (a) The consummation of: (l) any consolidation, merger or plan of share exchange involving the Company (a "Merger") as a result of which the holders of outstanding securities of the Company ordinarily having the right to vote for the election of directors ("Voting Securities") immediately prior to the Merger do not continue to hold at least 50% of the combined voting power of the outstanding Voting Securities of the surviving corporation or a parent corporation of the surviving corporation immediately after the Merger, disregarding any Voting Securities issued to or retained by such holders in respect of securities of any other party to the Merger;or (2) any consolidation, merger, plan of share exchange or other transaction involving Northwest Natural Gas Company ("NW Natural") as a result of which the Company does not continue to hold, directly or indirectly, at least 50% of the outstanding securities of NW Natural ordinarily having the right to vote for the election of directors; or (3) any sale, lease, exchange or other transfer (in one transaction or a series ofrelated transactions) of all, or substantially all, the assets of the Company or NW Natural; Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 198 o'f 210 6 (b) At any time during a period of two consecutive years, individuals who at the beginning of such period constituted the Board ("Incumbent Directors") shall cease for any reason to constitute at least a majority thereof; provided, however, that the term "Incumbent Director" shall also include each new director elected during such two-year period whose nomination or election was approved by two-thirds of the Incumbent Directors then in office; or (c) Any person (as such term is used in Section l4(d) ofthe Securities Exchange Act of 1934, other than the Company or any employee benefit plan sponsored by the Company or NW Natural) shall, as a result of a tender or exchange offer, open market purchases or privately negotiated purchases from anyone other than the Company, have become the beneficial owner (within the meaning of Rule I 3d-3 under the Securities Exchange Act of 1934), directly or indirectly, of Voting Securities representing twenty percent (20o/o) or more of the combined voting power of the then outstanding Voting Securities. 3.8 For purposes of this Agreement, "Shareholder Approval" shall be deemed to have occurred if the shareholders of the Company approve an agreement entered into by the Company, the consummation of which would result in the occurrence of a Change in Control. 3.9 For purposes of this Agreement, "Cood Reason" shall mean the occunence after Shareholder Approval, if applicable, or the Change in Control, of any of the following circumstances, but only if (x) Recipient gives notice to Employer of Recipient's intent to terminate employment for Good Reason within 30 days after the later of (l ) notice to Recipient of such circumstances, or (2) the Change in Control, and (y) such circumstances are not fully corrected by the Employer within 90 days after Recipient's notice: (a) the assignment to Recipient of a different title, job or responsibilities that results in a decrease in the level of Recipient's responsibility; provided that Good Reason shall not exist ifRecipient continues to have the same or a greater general level of responsibility for the former Employer operations after the Change in Control as Recipient had prior to the Change in Control even though such responsibilities have necessarily changed due to the former Employer operations becoming a subsidiary or division of the surviving company; (b) a reduction by the Employer in Recipient's base salary as in effect immediately prior to the earlier of Shareholder Approval, if applicable, or the Change in Control; (c) the failure by Employer to continue in effect any employee benefit or incentive plan in which Recipient is participating immediately prior to the earlier of Shareholder Approval, if applicable, or the Change in Control (or plans providing Recipient with at least substantially similar benefits) other than as a result of the normal expiration of any such plan in accordance with its terms as in effect immediately prior to the earlier of Shareholder Approval, if applicable, or the Change in Control, or the taking of any action, or the failure to act, by Employer which would adversely affect Recipient's continued participation in any of such plans on at least as favorable a basis to Recipient as is the case immediately prior to the earlier of Shareholder Approval, if applicable, or the Change in Control or which would materially reduce Recipient's benefits in the future under any of such plans or deprive Recipient Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 199 ot21O 7 of any material benefit enjoyed by Recipient immediately prior to the earlier of Shareholder Approval, if applicable, or the Change in Control; (d) the failure by the Employer to provide and credit Recipient with the number of paid vacation days to which Recipient is then entitled in accordance with the Employer's normal vacation policy as in effect immediately prior to the earlier of Shareholder Approval, if applicable, or the Change in Control; or (e) the Employer's requiring Recipient to be based more than 30 miles from where Recipient's office is located immediately prior to the earlier of Shareholder Approval, if applicable, or the Change in Control except for required travel on the Employer's business to an extent substantially consistent with the business travel obligations which Recipient undertook on behalf of the Employer prior to the earlier of Shareholder Approval, if applicable, or the Change in Control. 4. Dividend Equivalent Cash Award. The amount of the Dividend Equivalent Cash Award shall be determined by muttiplying the number of Performance Shares deliverable to Recipient as determined under Sections 2 and 3 by the total amount of dividends paid per share of the Company's Common Stock for which the dividend record date occuned after the beginning of the Award Period and before the date of delivery of the Performance Shares. 5. Certification and Payment. At the regularly scheduled meeting of the Committee held in February of the year immediately following the final year of the Award Period (the "Certification Meeting"), the Committee shall review the Company's results for the Award Period. Prior to the Certification Meeting, the Company shall calculate the number of Performance Shares deliverable and the amount of the Dividend Equivalent Cash Award payable to Recipient, and shall submit these calculations to the Committee. At or prior to the Certification Meeting, the Committee shallcertifi in writing (which may consist of approved minutes of the Certification Meeting) the number of Performance Shares deliverable to Recipient and the amount of the Dividend Equivalent Cash Award payable to Recipient. Subject to applicable tax withholding, the amounts so certified shall be delivered or paid (as applicable) on a date (the "Payment Date") that is the later of March 1,2022 or five business days following the Certification Meeting, and no amounts shall be delivered or paid prior to certification. No fractional shares shall be delivered and the numberofPerformance Shares deliverable shall be rounded to the nearest whole share. Notwithstanding the foregoing, if Recipient shall have made a valid election to defer receipt of Performance Shares or the Dividend Equivalent Cash Award pursuant to the terms of Northwest Natural's Defened Compensation Plan for Directors and Executives (the "DCP"), payment of the award shall be made in accordance with that election. 6. Tax Withholdine. Recipient acknowledges that, on the Payment Date when the Performance Shares are issued or otherwise delivered to Recipient, the Value (as defined below) on that date of the Performance Shares (as well as the amount of the Dividend Equivalent Cash Award) will be treated as ordinary compensation income for federal and state income and FICA tax purposes, and that the Employer will be required to withhold taxes on these income amounts. To satisfy the required withholding amount, the Employer shall first withhold all or part of the Dividend Equivalent Cash Award, and if that is insufficient, the Employer shall withhold the number of Performance Shares having a Value equal to the remaining withholding amount. For Exhibit 3 J. Palfreyman, Falls Water Co., lnc. Page 200 of 210 8 purposes of this Section 6, the "Value" of a Performance Share shall be equal to the closing market price for Company Common Stock on the last trading day preceding the Payment Date. Notrryithstanding the foregoing, Recipient may elect not to have Performance Shares withheld to cover taxes by giving notice to the Company in writing prior to the Payment Date, in which case the Performance Shares shall be issued or acquired in the Recipient's name on the Payment Date thereby triggering the tax consequences, but the Company shall retain the certificate for the Performance Shares as security until Recipient shall have paid to the Company in cash any required tax withholding not covered by withholding of the Dividend Equivalent Cash Award. 7.

The number of Performance Shares to be delivered as a pro-rated award under this Section 7 .2 shall be determined by multiplying the Target Share Amount by a fraction, the numerator of which is the number of days of the Award Period elapsed prior to the closing of the transaction and the denominator of which is the number of days in the Award Period. 8.

The Committee may, in its sole discretion, reduce the amount of Excess LTIP Compensation to be repaid by Recipient to take into account the tax consequences ofsuch repayment or any other factors. Ifany Performance Shares included in the Excess LTIP Compensation are sold by Recipient prior to the Company's demand for repayment (including any shares withheld for taxes under Section 6 of this Agreement), Recipient shall repay to the Company 100% of the proceeds of such sale or sales. The return of Excess LTIP Compensation is in addition to and separate from any other relief available to the Company due to Recipient's Misconduct. 9.2 "Misconduct" shallmean (a) willful commission by Recipient of an act of fraud or dishonesty resulting in economic or financial injury to the Company, (b) willful misconduct by Recipient that substantially impairs the Company's business or reputation, or (c) willful gross negligence by Recipient in the performance of his or her duties. 9.3 If any portion of the Performance Shares or the Dividend Equivalent Cash Award was deferred under the DCP, the Excess LTIP Compensation shall first be recovered by canceling all or a portion of the amounts so deferred under the DCP and any dividends or other eamings credited under the DCP with respect to such cancelled amounts. The Company may seek direct repayment from Recipient of any Excess LTIP Compensation not so recovered and may, to the extent permitted by applicable law, offset such Excess LTIP Compensation against any compensation or other amounts owed by the Company to Recipient. In particular, Excess LTIP Compensation may be recovered by offset against the after-tax proceeds of defened compensation payouts under the DCP, Northwest Natural's Executive Supplemental Retirement Income Plan or Northwest Natural's Supplemental Executive Retirement Plan at the times such deferred compensation payouts occur under the terms of those plans. Excess LTIP Compensation that remains unpaid for more than 60 days after demand by the Company shall accrue interest at the rate used from time to time for crediting interest under the DCP. 10.
