Reference is made to Note 16 of the Notes to Financial Statements. 10. None I l. ll/ashington General Rate Cases 2014 General Rate Cases In November 2014, the UTC approved an all-party settlement agreement related to Avista Corp.'s electric and natural gas general rate cases filed in February 2014 and new rates became effective on January 1,2015. The settlement was designed to increase annual electric base revenues by $12.3 million, or 2.5 percent, inclusive of a $5.3 million power supply update as required in the settlement agreement (explained below). The settlement was designed to increase annual natural gas base revenues by $8.5 million, or 5.6 percent. The settlement agreement also included the implementation of decoupling mechanisms for electric and natural gas and a related after-the-fact earnings test, which are discussed in further detail in Note 17 of the Notes to Financial Statements. Specific capital structure ratios and the cost of capital components were not agreed to in the settlement agreement. The revenue increases in the settlement were not tied to the 7 .32 percent rate of return on rate base (ROR) used in conjunction with the after-the fact earnings test. The electric and natural gas revenue increases were negotiated numbers, with each party using its own set of assumptions underlying its agreement to the revenue increases. The parties agreed thatthe 7.32 percent ROR will be used to calculate the AFUDC and other purposes. 2015 General Rate Cases ln January 2016, the Company received an order (Order 05) that concluded its electric and natural gas general rate cases that were originally filed with the UTC in February 2015. New electric and natural gas rates were effective on January 11,2016. The UTC approved rates designed to provid e a 1 .6 percent, or $8.1 million decrease in electric base revenue, and a 7 .4 percent, or $ 10.8 million increase in natural gas base revenue. The UTC also approved an ROR on rate base of 7 .29 percent, with a common equity ratio of 48.5 percent and a 9.5 percent return on equity (ROE). Throughout the rate case process, certain circumstances and costs changed, causing Avista Corp. to revise our overall proposed rate requests downward, especially for our electric operations. The Company's need for electric rate relief was reduced primarily due to the following: o a decrease in power supply costs of approximately $24.0 million caused by the continuing decline in the price of natural gas used to run the Company's natural gas-fired generation and lower contract costs associated with a new PPA from Chelan PUD, FERC FORM NO.2 108.2 Name of Respondent Avista Corporation This Report is: (1) X An Original(2\ A Resubmission Date of Report (Mo, Da, Yr) 04t15t2016 Year/Period of Report 2015tQ4 lmportant Chanqes Durinq the Quarter/Year . updated information related to federal tax adjustments and state allocations, o the delay in the expected completion date of the Nine Mile hydroelectric generation project upgrade from late 2015 to late 2016, and . a delay of the start date to begin amortization of existing electric meters from 2016 to a future year, associated with Avista Corp.'s proposed AMI project. The natural gas revenue increase approved by the UTC is related to the Company's ownership and operating costs to run the natural gas business. Changes in the commodity costs of natural gas for natural gas customers are reflected in Avista Corp.'s annual PGA, which is generally effective November lst each year. On November 1,2015 natural gas customers' bills were reduced approximately l5 percent related to the decline in the market price of naturalgas. ln responsive testirnony filed by the UTC Staff in July 2015 in the Company's electric and natural gas generalrate cases, they recommended a disallowance of $12.7 million (Washington's share) of the costs associated with the replacement of the Company's customer information and work management systems (Project Compass) primarily related to the delay in the completion of the project. In the January 6,2016 UTC order, they approved the full recovery of Washington's portion of Project Compass costs. WC Issues Order Denying Industrial Customers of Northwest Utilities / Public Counsel Joint Motionfor Clarification, WC Staff Motion to Reconsider ond UTC Staff Motion to Reopen Record On February 19,2016, the UTC issued an order (Order 06) denying the Motions summarized below and affirmed their original January 2016 order of an $8.1 million decrease in electric base revenue, thus finalizing Avista Corp's 201 5 electric and natural gas general rate cases. On January 19,2016, the lndustrial Customers of Northwest Utilities (ICNU) and the Public Counsel Unit of the Washington State Office of the Attorney General (PC) filed a Joint Motion for Clarification with the UTC. In its Motion for Clarification, ICNU and PC requested that the UTC clarifu the calculation of the electric attrition adjustment and the end-result revenue decrease of $8.1 million. ICNU and PC provided their own calculations in their Motion, and suggested that the revenue decrease should have been $19.8 million based on their reading of the UTC's Order. On January 19,2016, the UTC Staff, which is a separate party in the general rate case proceedings from the UTC Advisory Staff that supports the Commissioners, filed a Motion to Reconsider with the UTC. ln its Motion to Reconsider, the Staffprovided calculations and explanations that suggested that the electric revenue decrease should have been a revenue decrease of $27 .4 million instead of $8.1 million, based on its reading of the UTC's Order. Further, on February 4,2016, the UTC Staff filed a Motion to Reopen Record for the Limited Purpose of Receiving into Evidence Instruction on Use and Application of Staff s Attrition Model, and sought to supplement the record "to incorporate all aspects of the Company' Power Cost Update." Within this Motion, UTC Staff updated its suggested electric revenue decrease to $19.6 million. None of the parties in their Motions raised issues with the UTC's decision on the natural gas revenue increase of FERC FORM NO,2 (12 108.3 Name of Respondent Avista Corporation This Report is: (1) X An OriginalQ\ A Resubmission Date of Report (Mo, Da, Yr) o4t15120',16 Year/Period of Report 20151Q4 lmoortant Chanqes Durinq the Quarter/Year $10.8 million. PC Petitionfor Judicial Review On March I 8, 20 I 6, PC filed in Thurston County Superior Court a Petition for Judicial Review of the UTC's January 2016 Order 05 and February 2016 Order 06. Order 05 approved new electric and natural gas rates that became effective on January 11,2016. ln its March 2016 Petition for Judicial Review, PC seeks judicial review of five aspects of Order 05 and Order 06, alleging, among other things, that (l) the UTC exceeded its statutory authority by setting rates for Avista Corp.'s natural gas and electric services based on amounts for utility plant and facilities that are not "used and useful" in providing utility service to customers; (2) the UTC acted arbitrarily and capriciously in granting an attrition adjustment for Avista Corp.'s electric operations after finding that the Company did not meet the newly articulated standard regarding attrition adjustments; (3) the UTC ened in applying the "end results test" to set rates for Avista Corp.'s electric operations that are not supported by the record; (4) the UTC did not correct its calculation of Avista Corp.'s electric rates after significant errors were brought to its aftention; and (5) the UTC's calculation of Avista Corp.'s electric rates lacks substantial evidence. PC is requesting that the Court (1) vacate or set aside portions of the UTC's orders; (2) identifr the errors contained in the UTC's orders; (3) find that the rates approved in Order 05 and reaffirmed in Order 06 are unlawful and not fair, just and reasonable; (4) remand the matter to the UTC for further proceedings consistent with these rulings, including a determination of Avista Corp.'s revenue requirement for electric and natural gas services; and (5) find the customers are entitled to a refund. The new rates established by Order 05 will continue in effect while the Petition for Judicial Review is being considered. The Company believes the UTC's Order 05 and Order 06 finalizing the electric and natural gas generalrate cases provide a reasonable end result for all parties. If the outcome of the judicial review were to result in an electric.rate reduction greater than the decrease ordered by the UTC, it may not provide Avista Corp. with a reasonable opportunity to earn the rate of return authorized by the UTC. 2016 General Rate Cases On February 19,2016, Avista Corp. filed electric and natural gas general rates cases with the UTC. The Company's proposal includes an I 8-month rate plan, with new rates taking effect on January l, 2017 and January I , 20 I 8. Under this plan, the Company would not file a future rate case for new rates to be effective prior to July 1, 2018. The 2017 increase, if approved, would increase overall base electric rates 7.8 percent (designed to increase annual electric revenues by $38.6 million) and overallbase natural gas rates 5.0 percent (designed to increase annual natural gas revenues by $4.a million). In addition, the Company has requested a second step increase effective January 1,2018, which would increase overall base electric rates by 3.9 percent (designed to increase annual electric revenues by $10.3 million) and overall base natural FERC FORM NO.2 (12 108.4 Name of Respondent Avista Corporation This Report is: (1) X An Original(2\ A Resubmission Date of Report (Mo, Da, Yr) 04t15t2016 Year/Period of Report 2015tQ4 lmportant Chanqes Durinq the Quarterf/ear gas rates by 1.8 percent (designed to increase annual natural gas revenues by $0.9 million). Avista Corp. has proposed to offset the electric increase, for the period January through June 2018, with available ERM dollars. As a result, customers would not see an electric general rate case bill increase in 20 I 8 prior to July I , 201 8. The requests are bas&d on a proposed ROR of 7 .64 percent with a common equity ratio of 48.5 percent and. a 9 .9 percent ROE. The UTC has up to I 1 months to review the filings and issue a decision. Idaho General Rate Cases 2014 Rate Plan Extension Avista Corp. did not file new general rate cases in Idaho in2014; instead, the Company developed an extension to the 2013 and 2014 rate plan and reached a settlement agreement with all interested parties. ln September 2014, the IPUC approved the settlement, which reflected agreement among all interested parties, for a one-year extension to the Company's current rate plan, which was set to expire on December 31,2014. Under the approved extension, base retail rates remained unchanged through December 31, 2015. The settlement provided an estimated $3.7 million increase in pre-tax income by reducing planned expenses in 2015 for the Company's Idaho operations. 2015 General Rate Cases In December 2015, the IPUC approved a settlement agreement between Avista Corp. and all interested parties related to its electric and naturirl gas general rate cases, which were originally filed with the IPUC on June l, 2015. New rates were effective on January 1,2016. The settlement agreement is designed to increase annual electric base revenues by $1.7 million or 0.7 percent and annual natural gas base revenues by $2.5 million or 3.5 percent. The settlement is based on a ROR of 7 .42 percent with a common equity ratio of 50 percent and a 9.5 percent ROE. The settlement agreement also reflects the following: o the discontinuation of the after-the-fact earnings test (provision for earnings sharing) that was originally agreed to as part ofthe settlement ofour 2012 electric and natural gas general rate cases, and r the implementation of electric and natural gas Fixed Cost Adjustment mechanisms, as discussed in Note 17 of the Notes to Financial Statements. Oregon General Rate Cases 2014 General Rate Case In January 2015, Avista Corp. filed an all-party settlement agreement with the OPUC related to our natural gas general rate case, which was originally filed in September 2014. On February 23,2015, the OPUC issued an order rejecting the all-party settlement agreement. The OPUC expressed concems related to, among other things, various rate design issues. In March 2015, Avista Corp. filed an amended all-party settlement agreement with the OPUC which addressed the FERC FORM NO.2 (12.108.5 Name of Respondent Avista Corporation This Report is: (1) X An Original(2\ A Resubmission Date of Report (Mo, Da, Yr) 04t15t2016 Year/Period of Report 2015tQ4 lmportant Changes Durins the Quarter/Year OPUC's concerns regarding the initial settlement agreement. The amended settlement agreement was designed to increase base natural gas revenues by $5.3 million. Included in this base rate increase is $0.3 million in base revenues that we are already receiving from customers through a separate rate adjustment. Therefore, the net increase in base revenues was $5.0 million, or 4.9 percent on a billed basis. The parties requested that new retail rates become effective on April 16, 20 1 5 . On April 9, 20 I 5, the OPUC issued an Order approving the amended settlement agreement as filed. This settlement agreement provided for an overall authorized ROR of 7.516 percent with a common equity ratio of 51 percent and a 9.5 percent ROE. 2015 General Rate Case On February 29,2016, the OPUC issued an order concluding the Company's natural gas general rate case, which was originally filed with OPUC in May 2015. The OPUC order approved rates designed to increase overall billed natural gas rates by 4.9 percent (designed to increase annual natural gas revenues by $4.5 million). New rates went into effect on March 1,2016. The final OPUC order incorporated the two partial settlement agreements described in further detail below. The OPUC order provides for an overall authorized ROR of 7.458 percent with a common equity ratio of 50 percent and a 9.4 percent ROE. In November 2015, Avista Corp. and all parties to the natural gas general rate case reached agreement on certain issues, and a partial settlement agreement was filed with the OPUC on November 6,2015. The partial settlement agreement reduced the requested natural gas revenue increase from $8.6 million to $6,7 million or 6.3 percent (on a billed basis). The partial settlement resolved a number of issues including the calculation of state income taxes for rate-making purposes, wages and salaries, the revenue forecast for the rate period, and working capital. In addition, the November partial settlement agreement included a provision for the implementation of a decoupling mechanism, similar to the Washington and Idaho mechanisms described in Note l7 of the Notes to Financial Statements. The Decoupling Mechanism has an initialterm concluding in September 2019. On January 19,2016, the Company entered into an additional all-party partial settlement to further reduce the revenue increase request to $6.1 million or 5.7 percent (on a billed basis), related to updated information related to deferred taxes and its effect on rate base. These agreements did not resolve the remaining issues, such as, the appropriate ROE and capital structure, the appropriate level of additions to rate base, and medical and pension expenses. In addition, the OPUC staff filed testimony which included a recommendation to disallow $1.2 million (Oregon's share) of Project Compass costs primarily related to the delay in the full completion of the project. In the February 29,2016 OPUC order, the OPUC approved the full recovery of Oregon's portion of Project Compass costs, as well as the capital investment included in the Company's case. The reductions to the Company's revenue requirement related to employee incentives, pension expense, and the reduction in the Company's proposed cost of capital. 12.

NOTES TO FINANCIAL STATEMENTS NOTE I. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Business Avista Corp. is primarily an electric and natural gas utility with certain other business ventures. Avista Corp. provides electric distribution and transmission, and natural gas distribution services in parts of eastem Washington and northern Idaho. Avista Corp. also provides natural gas distribution service in parts ofnortheastern and southwestern Oregon. Avista Corp. has electric generating facilities in Washington, Idaho, Oregon and Montana. Avista Corp. also supplies electricity to a small number of customers in Montana, most of whom are employees who operate Avista Corp.'s Noxon Rapids generating facility. On July 1,2014, Avista Corp. acquired AERC, and as of that date, AERC became a wholly-owned subsidiary of Avista Corp. The FERC FORM NO.2/3-Q 12-0 122.1 Name of Respondent Avista Corporation This Report is: (1) X An OriginalQ\ A Resubmission Date of Report (Mo, Da, Yr) 04t15t2016 Year/Period of Report 2015tQ4 Notes to Financial Statements primary subsidiary of AERC is AEL&P, comprising regulated electric utility operations in Juneau, Alaska. There are no AERC earnings included in the overall results of Avista Corp. prior to July 1,2014. See Note 3 for information regarding the acquisition of AERC. Avista Capital, a wholly owned subsidiary of Avista Corp., is the parent company of all of the subsidiary companies except AERC. During the first half of 2014 and prior, Avista Capital's subsidiaries included Ecova, which was an 80.2 percent owned subsidiary prior to its disposition on June 30,2014. Ecova was a provider of energy efficiency and other facility information and cost management programs and services for multi-site customers and utilities throughout North America. See Note 4 for information regarding the disposition of Ecova. Basis of Reporting The financial statements include the assets, liabilities, revenues and expenses ofthe Company and have been prepared in accordance with the accounting requirements of the Federal Energy Regulatory Commission (FERC) as set forth in its applicable Uniform System of Accounts and published accounting releases, which is a comprehensive basis of accounting other than accounting principles generally accepted in the United States of America (U.S. GAAP). As required by the FERC, the Company accounts for its investment in majority-owned subsidiaries on the equity method rather than consolidating the assets, liabilities, revenues, and expenses of these subsidiaries, as required by U.S. GAAP. The accompanying financial statements include the Company's proportionate share of utility plant and related operations resulting from its interests in jointly owned plants. In addition, under the requirements of the FERC, there are differences from U.S. GAAP in the presentation of (l) current portion of long-term debt (2) assets and liabilities for cost of removal of assets, (3) assets held for sale, (4) regulatory assets and liabilities, (5) defened income taxes associated with accounts other than utility properfy, plant and equipment, (6) comprehensive income, (7) unamortized debt issuance costs and (8) operating revenues and resource costs associated with settled energy contracts that are "booked out" (not physically delivered). Use of Estimates The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported for assets and liabilities and the disclosure ofcontingent assets and liabilities at the date ofthe financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates include: r determining the market value of energy commodity derivative assets and . pension and other postretirement benefit plan obligations, o contingent liabilities, r goodwill impairment testing, . recoverability ofregulatory assets, and o unbilled revenues. Changes in these estimates and assumptions are considered reasonably possible and may have a material effect on the financial statements and thus actual results could differ from the amounts reported and disclosed herein. System of Accoants The accounting records of the Company's utility operations are maintained in accordance with the uniform system of accounts prescribed by the FERC and adopted by the state regulatory commissions in Washington, Idaho, Montana and Oregon. Regulation FERC FORM NO.2/3-Q 12-O7 122.2 Name of Respondent Avista Corporation This Report is: (1) X An Original(2\ A Resubmission Date of Report (Mo, Da, Yr) 04t151?016 Year/Period of Report 2U5tA4 Notes to Financial Statements The Company is subject to state regulation in Washington, Idaho, Montana and Oregon. The Company is also subject to federal regulation primarily by the FERC, as well as various other federal agencies with regulatory oversight of parlicular aspects of its operations. Operating Revenues Operating revenues related to the sale of energy are recorded when service is rendered or energy is delivered to customers. The determination of the energy sales to individual customers is based on the reading of their meters, which occurs on a systematic basis throughout the month. At the end of each calendar month, the amount of energy delivered to customers since the date of the last meter reading is estimated and the corresponding unbilled revenue is estimated and recorded. Our estimate of unbilled revenue is based on: . the number of customers, . current rates, o rl€ter reading dates, actual native load for electricity, actual throughput for natural gas, and o electric line losses and natural gas system losses. Any difference between actual and estimated revenue is automatically corrected in the following month when the actual meter reading and customer billing occurs. Accounts receivable includes unbilled energy revenues of the following amounts as of December 3l (dollars in thousands): 2015 2014 Unbilled accounts receivable 59,405 $78,007 Depreciotion For utility operations, depreciation expense is estimated by a method of depreciation accounting utilizing composite rates for utility plant. Such rates are designed to provide for retirements of properties at the expiration of their service lives. For utility operations, the ratio of depreciation provisions to average depreciable property was as follows for the years ended December 3 1: 20ls 2014 Ratio ofdepreciation to average depreciable property 3.09% 2.97% The average service lives for the following broad categories of utility plant Electric thermal/other production Hydroelectric production Electric transmission Electric distribution in service are (in years): Avista Corp. 40 79 57 36 FERC FORM NO. 2/3-Q (REV 12-07)122.3 Name of Respondent Avista Corporation This Report is: (1) X An OriginalQ\ A Resubmission Date of Report (Mo, Da, Yr) 04t1512016 Year/Period of Report 2015tQ4 Notes to Financial Statements Natural gas distribution properfy Taxes Otlter Than Income Taxes Taxes other than income taxes include state excise taxes, city occupational and franchise taxes, real and personal properly taxes and certain other taxes not based on net income. These taxes are generally based on revenues or the value ofproperty. Utility related taxes collected from customers (primarily state excise taxes and city utility taxes) are recorded as operating revenue and expense and totaled the following amounts for the years ended December 3l (dollars in thousands): 2015 2014 Utility taxes $ 57,716 $ 57,599 Allowancefor Funds Used During Construction The AFUDC represents the cost of both the debt and equity funds used to lurance utility plant additions during the construction period As prescribed by regulatory authorities, AFUDC is capitalized as a part of the cost of utility plant and the debt component is credited against total interest expense in the Statements of Income in the line item "capitalized interest." The equity component of AFUDC is included in the Statement of Income in the line item "other income-net." The Company is permitted, under established regulatory rate practices, to recover the capitalized AFUDC, and a reasonable return thereon, through its inclusion in rate base and the provision for depreciation after the related utility plant is placed in service. Cash inflow related to AFUDC does not occur until the related utility plant is placed in service and included in rate base. The effective AFUDC rate was the following for the years ended December 3 l: 20tS 2014 Effective AFUDC rate 7.32%7.64% Income Taxes A defened income tax asset or liability is determined based on the enacted tax rates that will be in effect when the differences between the financial statement carrying amounts and tax basis of existing assets and liabilities are expected to be reported in the Company's consolidated income tax retums. The deferred income tax expense for the period is equal to the net change in the deferred income tax asset and liability accounts from the beginning to the end of the period. The effect on deferred income taxes from a change in tax rates is recognized in income in the period that includes the enactment date. Deferred income tax liabilities and regulatory assets are established for income tax benefits flowed through to customers. The Company recognizes the effect of state tax credits, which are generated from utility plant, as they are utilized. The Company did not incur any penalties on income tax positions in 20 I 5 or 2074. The Company would recognize interest accrued related to income tax positions as interest expense and any penalties incurred as other income deductions. Stock-B ased Comp ensation The Company cunently issues three types of stock-based compensation awards - restricted shares, market-based awards and performance-based awards. Historically, these stock compensation awards have not been material to the Company's overall financial results. Compensation cost relating to share-based payment transactions is recognized in the Company's financial statements based on the fair value of the equity or liabilify instruments issued and recorded over the requisite service period. The Company recorded stock-based compensation expense (included in other operating expenses) and income tax benefits in the Statements of Income of the following amounts for the years ended December 3l (dollars in thousands): 45 20t5 2014 FERC FORM NO.2/3.Q 1 122 4 Name of Respondent Avista Corporation This Report is: (1)X An OriginalQ\ A Resubmission Date of Report (Mo, Da, Yr) 04t15t2016 Year/Period of Report 2015tA4 Notes to Financial Statements Stock-based compensation expense Income tax benefits Restricted Shares Shares granted during the year Shares vested during the year Unvested shares at end ofyear Unrecognized compensation expense at end ofyear (in thousands) TSR Awards TSR shares granted during the year TSR shares vested during the year TSR shares earned based on market metrics Unvested TSR shares at end ofyear 6,974 $ 2,420 6,007 2,102 Restricted share awards vest in equal thirds each year over a three-year period and are payable in Avista Corp. common stock at the end of each year if the service condition is met. In addition to the service condition, the Company must meet a return on equity target in order for the CEO's restricted shares to vest. Restricted stock is valued at the close of market of the Company's common stock on the grant date. Total Shareholder Retum (TSR) awards are market-based awards and Cumulative Eamings Per Share (CEPS) awards are performance awards. CEPS awards were frst granted in20l4. Both types of awards vest after a period of three years and are payable in cash or Avista Corp. common stock at the end of the three-year period. The method of seftlement is at the discretion of the Company and historically the Company has settled these awards through issuance of Avista Corp. common stock and intends to continue this practice. Both types of awards entitle the recipients to dividend equivalent rights, are subject to forfeiture under certain circumstances, and are subject to meeting specific market or performance conditions. Based on the level of attainment of the market or performance conditions, the amount of cash paid or common stock issued will range from 0 to 200 percent of the initial awards granted. Dividend equivalent rights are accumulated and paid out only on shares that eventually vest and have met the market and performance conditions. For both the TSR awards and the CEPS awards, the Company accounts for them as equity awards and compensation cost for these awards is recognized over the requisite service period, provided that the requisite service period is rendered. For TSR awards, ifthe market-condition is not met at the end of the three-year service period, there will be no change in the cumulative amount of compensation cost recognized, since the awards are still considered vested even though the market metric was not met. For CEPS awards, at the end of the three-year service period, if the internal performance metric of cumulative earnings per share is not met, all compensation cost for these awards is reversed as these awards are not considered vested. The fair value of each TSR award is estimated on the date of grant using a statistical model that incorporates the probability of meeting the market targets based on historical returns relative to a peer group. The estimated fair value of the equity component of CEPS awards was estimated on the date of grant as the share price of Avista Corp. comrnon stock on the date of grant, less the net present value of the estimated dividends over the three-year period. The following table summarizes the number of grants, vested and unvested shares, earned shares (based on market metrics), and other pertinent information related to the Company's stock compensation awards for the years ended December 3l: 201 5 2014 58,302 (60,379) 106,091 1,705 $ 116,435 222,734 223,697 62,075 (52,899) 112,042 1,349 I 17,550 97,199 287,834 (171,334) (167,584) FERC FORM NO. 2/3-Q (REV 122.5 Name of Respondent Avista Corporation This Report is: (1) X An Original(2\ A Resubmission Date of Report (Mo, Da, Yr) 04t15t2016 Year/Period of Report 2015tQ4 Notes to Financial Statements Unrecognized compensation expense (in thousands) CEPS Awards CEPS shares granted during the year Unvested CEPS shares at end ofyear Unrecognized compensation expense (in thousands) 3,219 $ 58,259 I I 1,887 1,840 s 2,833 59,025 58,017 1,577 Outstanding TSR and CEPS share awards include a dividend component that is paid in cash. This component of the share grants is accounted for as a liability award. These liability awards are revalued on a quarterly basis taking into account the number of awards outstanding, historical dividend rate, the change in the value of the Company's common stock relative to an external benchmark (TSR awards only) and the amount of CEPS earned to-date compared to estimated CEPS over the performance period (CEPS awards only). Over the life of these awards, the cumulative amount of compensation expense recognized will match the actual cash paid. As of December3l,20l5 and2014,theCompanyhadrecognizedcumulativecompensationexpenseandaliabilityof$l.5millionand$1.3 million, respectively, related to the dividend component on the outstanding and unvested share grants. Cash and Cash Equivalents For the purposes of the Statements of Cash Flows, the Company considers all temporary investments with a maturity of three months or less when purchased to be cash equivalents. A llow an ce fo r Do u btful Ac c o unls The Company maintains an allowance for doubtful accounts to provide for estimated and potential losses on accounts receivable. The Company determines the allowance for utility and other customer accounts receivable based on historical write-offs as compared to accounts receivable and operating revenues. Additionally, the Company establishes specific allowances for certain individual accounts. Utility Plant in Service The cost of additions to utility plant in service, including an allowance for flrnds used during construction and replacements of units of properry and improvements, is capitalized. The cost of depreciable units of property retired plus the cost of removal less salvage is charged to accumulated depreciation. Ass el Ret irement O b lig ttt io ns The Company records the fair value of a liability for an asset retirement obligation (ARO) in the period in which it is incurred. When the liability is initially recorded, the associated costs of the ARO are capitalized as part of the carrying amount of the related long-lived asset. The liability is accreted to its present value each period and the related capitalized costs are depreciated over the useful life of the related asset. In addition, if there are changes in the estimated timing or estimated costs of the AROs, adjustments are recorded during the period new information becomes available as an increase or decrease to the liability, with the offset recorded to the related long-lived asset. Upon retirement of the asset, the Company either settles the ARO for its recorded amount or incurs a gain or loss. The Company records regulatory assets and liabilities for the difference between asset retirement costs currently recovered in rates and AROs recorded since asset retirement costs are recovered through rates charged to customers (see Note 7 for further discussion of the Company's asset retirement obligations). Derivative Assets and Liabilities Derivatives are recorded as either assets or liabilities on the Balance Sheets measured at estimated fair value. In certain defined conditions, a derivative may be specifically designated as a hedge for a particular exposure. The accounting for a derivative depends FERC FORM NO.2/3.Q 12-O 122.6 Name of Respondent Avista Corooration This Report is: (1)X An OriginalQ\ A Resubmission Date of Report (Mo, Da, Yr) 04t15t2016 Year/Period of Report 2015to,4 Notes to Financial Statements on the intended use ofsuch derivative and the resulting designation. The UTC and the IPUC issued accounting orders authorizing Avista Corp. to offset energy commodity derivative assets or liabilities with a regulatory asset or liability. This accounting treatment is intended to defer the recognition of mark-to-market gains and losses on energy commodity transactions until the period of delivery. The orders provide for Avista Corp. to not recognize the unrealized gain or loss on utility derivative commodity instruments in the Statements of Income. Realized gains or losses are recogrized in the periods of delivery, subject to approval for recovery through retail rates. Realized gains and losses, subject to regulatory approval, result in adjustments to retail rates through purchased gas cost adjustments, the ERM in Washington, the PCA mechanism in Idaho, and periodic general rates cases. Regulatory assets are assessed regularly and are probable for recovery through future rates. Substantially all forward contracts to purchase or sell power and natural gas are recorded as derivative assets or liabilities at estimated fair value with an offsetting regulatory asset or liability. Contracts that are not considered derivatives are accounted for on the accrual basis until they are settled or realized, unless there is a decline in the fair value ofthe contract that is determined to be other-than-temporary. For interest rate swap agreements, each period Avista Corp. records all mark-to-market gains and losses as assets and liabilities and records offsetting regulatory assets and liabilities, such that there is no income statement impact. Upon seftlement of interest rate swaps, the regulatory asset or liability (included as part of long-term debt) is amortized as a component of interest expense over the term of the associated debt. While the Company has not received any formal accounting orders from the various state commissions allowing for the offset of interest rate swap assets and liabilities with regulatory assets and liabilities, the Company has deemed this accounting treatment appropriate and future recovery probable due to the regulatory precedents set in prior general rate cases and the fact that the state commissions view interest rate swap derivatives as risk management tools similar to energy commodity derivatives. As of December 3 I , 20 15, the Company has multiple master netting agreements with a variety of entities that allow for cross-commodity netting of derivative agreements with the same counterparty (i.e. power derivatives can be netted with narural gas derivatives) under ASC 815-10-45. The Company does not have any agreements which allow for cross-affiliate netting among multiple affiliated legal entities. The Company nets all derivative instruments when allowed by the agreement for presentation in the Balance Sheets. Fair Value Messurements Fair value represents the price that would be received when selling an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. Energy commodity derivative assets and liabilities, deferred compensation assets, as well as derivatives related to interest rate swap agreements and foreign currency exchange contracts, are reported at estimated fair value on the Balance Sheets. See Note 14 for the Company's fair value disclosures. Regulatory Deferred Charges and Credits The Company prepares its financial statements in accordance with regulatory accounting practices because: . rates for regulated services are established by or subject to approval by independent third-party regulators, r the regulated rates are designed to recover the cost ofproviding the regulated services, and . in view of demand for the regulated services and the level of competition, it is reasonable to assume that rates can be charged to and collected from customers at levels that will recover costs. Regulatory accounting practices require that certain costs and/or obligations (such as incurred power and natural gas costs not currently included in rates, but expected to be recovered or refunded in the future), are reflected as deferred charges or credits on the Balance Sheets. These costs and/or obligations are not reflected in the Statements of Income until the period during which matching FERC FORM NO. 2/3-Q (REV 1 't22 7 Name of Respondent Avista Corporation This Report is: (1) X An OriginalQ\ A Resubmission Date of Report (Mo, Da, Yr) o4115t2016 Year/Period of Report 201slQ4 Notes to Financial Statements revenues are recognized. The Company also has decoupling revenue deferrals, which began in 2015. As opposed to cost deferrals which are not recognized in the Statements of Income until they are included in rates, decoupling revenue is recognized in the Statements of Income during the period it occurs (i.e. during the period of revenue shortfall or excess due to fluctuations in customer usage), subject to certain limitations, and a regulatory asseVliability is established which will be surcharged or rebated to customers in furure periods. GAAP requires that for any alternative regulatory revenue program, like decoupling, the revenue must be collected from customers within 24 months of the deferral to qualif, for recognition in the current period Statement of Income. Any amounts included in the Company's decoupling program that won't be collected from customers within 24 months are not recorded in the financial statements until the period in which revenue recognition criteria are met. This could ultimately result in more decoupling revenue being collected from customers over the life of the decoupling program than what is defened and recognized in the current period fi nancial statements. If at some point in the future the Company determines that it no longer meets the criteria for continued application of regulatory accounting practices for all or a portion ofits regulated operations, the Company could be: o roQUired to write off its regulatory assets, and . precluded fiom the future deferral ofcosts or decoupled revenues not recovered through rates at the time such amounts are incurred, even if the Company expected to recover these amounts from customers in the future. Investment in Exchange Power-Net The investment in exchange power represents the Company's previous investment in Washington Public Power Supply System Project 3 (WNP-3), a nuclear project that was terminated prior to completion. Under a settlement agreement with the Bonneville Power Administration in 1985, Avista Corp. began receiving power in 1987, for a32.5-year period, related to its investrnent in WNP-3. Through a settlement agreement with the UTC in the Washington jurisdiction, Avista Corp. is amortizing the recoverable portion of its investrnent in WNP-3 (recorded as investment in exchange power) over a 32.5-year period that began in I 987. For the Idaho jurisdiction, Avista Corp. fully amortized the recoverable portion of its investment in exchange power. Unamortized Debt Expense Unamoftized debt expense includes debt issuance costs that are amortized over the life of the related debt. Unamortized Loss on Reocquired Debt For the Company's Washington regulatory jurisdiction and for any debt repurchases beginning in2007 in all jurisdictions, premiums paid to repurchase debt are amortized over the remaining life of the original debt that was repurchased or, if new debt is issued in connection with the repurchase, these costs are amortized over the life of the new debt. ln the Company's other regulatory jurisdictions, premiums paid to repurchase debt prior to2007 are being amortized over the average remaining maturity of outstanding debt when no new debt was issued in connection with the debt repurchase. These costs are recovered through retail rates as a component of interest expense. App r op r iate d Reta ined E o rnings In accordance with the hydroelectric licensing requirements of section l0(d) of the Federal Power Act (FPA), the Company maintains an appropriated retained earnings account for any earnings in excess of the specified rate of return on the Company's investment in the licenses for its various hydroelectric projects. Per section l0(d) of the FPA, the Company must maintain these excess earnings in an appropriated retained earnings account until the termination of the licensing agreements or apply them to reduce the net inveshnent in the licenses of the hydroelectric projects at the discretion of the FERC. The Company typically calculates the earnings in excess of the specified rate ofretum on an annual basis, usually during the second quarter.

Future minimum lease payments required under operating leases having initial or remaining noncancelable lease terms in excess of one year were not material as of December 3 1 , 20 I 5. Equity in Earnings of Subsidiaries The Company records all the earnings from its subsidiaries under the equity method. The Company had the following equity in earnings of its subsidiaries for the years ended December 31 (dollars in thousands): 2014 Avista Capital Alaska Energy and Resources Company Total equity in earnings of subsidiary companies 4,857 $ 6,308 79,183 3,179 $ u,165 $82,362 Avista Capital, a wholly owned subsidiary of Avista Corp., is the parent company of all of the subsidiary companies, except AERC (and its subsidiaries). Avista Capital's subsidiaries and investments include sheet metal fabrication, venture fund investments, real estate investments, a company that explores markets that could be served with LNG and Ecova prior to its disposition on June 30, 2014. AERC, a wholly-owned subsidiary of Avista Corp. acquired on July 1,2014, is the parent company to all the Alaska subsidiary companies. The primary subsidiary of AERC is AEL&P, comprising the regulated utility operations in Alaska. Also, AERC owns AJT Mining Properties, Inc., an inactive mining company holding certain properties. Subsequent Events Management has evaluated the impact of events occurring after December 31, 2015 up to February 24,2016, the date that Avista Corp.'s U.S. GAAP financial statements were issued and has updated such evaluation for disclosure purposes through April 15, 2016. These financial statements include all necessary adjustments and disclosures resulting from these evaluations. Contingencies The Company has unresolved regulatory, legal and tax issues which have inherently uncertain outcomes. The Company accrues a loss contingency if it is probable that a liability has been incurred and the amount of the loss or impairment can be reasonably estimated. The Company also discloses losses that do not meet these conditions for accrual, if there is a reasonable possibility that a material loss may be incurred. As of December 3 I , 20 I 5, the Company has not recorded any significant amounts related to unresolved contingencies. See Note l6 for further discussion of the Company's commitments and contingencies. NOTE 2. NEW ACCOUNTING STANDARDS In April 2014, theFASB issued ASU No. 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and FERC FORM NO. 2/3-Q (REV 12-07)122.9 Name of Respondent Avista Corporation This Report is: (1) X An Originale\ A Resubmission Date of Report (Mo, Da, Yr) 04t15t2016 Year/Period of Report 20'l5lQ4 Notes to Financial Statements Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity," This ASU amends the definition ofa discontinued operation and requires entities to provide additional disclosures about discontinued operations as well as disposal transactions that do not meet the discontinued-operations criteria. ASU 20 l4-08 makes it more difficult for a disposal transaction to qualifu as a discontinued operation. In addition, the ASU requires entities to reclassifu assets and liabilities ofa discontinued operation for all comparative periods presented in the Balance Sheet rather thanjust the current period, and it requires additional disclosures on the face of the Statement of Cash Flows regarding discontinued operations. This ASU became effective for periods beginning on or after December 15,2014; however, early adoption was permitted. The Company evaluated this standard and determined that it would not early adopt this standard. Since the disposition of Ecova occurred before the effective date of this standard, and the Company did not early adopt this standard, there is no impact on the Company's financial condition, results of operations and cash flows in the current year. In May 2014,the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)," which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that an entity identifies the various performance obligations in a contract, allocates the transaction price among the performance obligations and recognizes revenue as the entity satisfies the performance obligations. This ASU was originally effective for periods beginning after December 15, 2016 and early adoption is not permitted. In August 2015, the FASB issued ASU 2015-14 Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which deferred the effective date of ASU 2014-09 for one year, with adoption as of the original date permitted. However, while this ASU is not effective until 2018, it will require retroactive application to all periods presented in the financial statements. As such, at adoption in 20 I 8, amounts in 2016 and 2017 may have to be revised or a cumulative adjustment to opening retained earnings may have to be recorded. The Company is evaluating this standard and cannot, at this time, estimate the potential impact on its future financial condition, results of operations and cash flows. In February 201 5, the FASB issued ASU No. 2015-02, "Consolidation (Topic 8 I 0): Amendments to the Consolidation Analysis." This ASU significantly changes the consolidation analysis required under GAAP, including the identification of variable interest entities (VIE). The ASU also removes the deferral of the VIE analysis related to investments in certain investment funds, which will result in a different consolidation evaluation for these lypes of invesffnents. This ASU is effective for periods beginning on or after December 15, 2015; however, early adoption is permitted. The Company evaluated this standard and determined that it will not early adopt this standard. The Company is evaluating this standard and cannot, at this time, estimate the potential impact on its future financial condition, results of operations and cash flows. In April 20 15, the FASB issued ASU No. 20 I 5-05, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Fees Paid in a Cloud Computing Arrangement." This ASU provides guidance on how organizations should account for fees paid in a cloud computing arrangement, including helping organizations understand whether their arrangement includes a software license. If the arrangement includes a software license, the software license would be accounted for in a manner consistent with internal-use software. If a cloud-computing arrangement does not include a software license, the customer is required to account for the arrangement as a service contract. This ASU is effective for periods beginning on or after December 15,2015; however, early adoption is permitted. The Company evaluated this standard and determined that it will not early adopt this standard. Upon adoption, an entity can elect to apply this ASU prospectively or retroactively and disclose the method selected. The Company is evaluating this standard and cannot, at this time, estimate the potential impact on its future financial condition, results of operations and cash flows. In May 2015, the FASB issued ASU No. 2015-07, "Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)." This ASU removes, from the fair value hierarchy, investments for which the practical expedient is used to measure fair value at net asset value (NAV). Instead, an entity is required to include those investments as a reconciling line item so that the total fair value amount of investments in the disclosure is consistent FERC FORM NO.2/3-Q 't2-07 122.10 Name of Respondent Avista Corporation This Report is: (1) X An OriginalQ\ A Resubmission Date of Report (Mo, Da, Yr) 04t15t2016 Year/Period of Report 2015tQ4 Notes to Financial Statements with the amount on the balance sheet. Further, entities must provide certain disclosures for investments for which they elect to use the NAV practical expedient to determine fair value. This ASU is effective for periods beginning on or after December 15,2015 and early adoption is permitted. The Company evaluated this standard and determined that it will early adopt this standard as of December 3 l, 2015. As required, this ASU is being applied retrospectively to all periods presented. The adoption of this standard did not affect the Company's future financial condition, results of operations and cash flows; however, it did affect the Company's disclosures. See Note 8 and l4 for the expanded disclosures surrounding the adoption of this ASU. In February 2016, the FASB issued ASU 2016-02 "Leases (Topic 842)." This ASU introduces a new lessee model that brings most leases on the balance sheet. The standard also aligns certain of the underlying principles of the new lessor model with those in ASC 606, the FASB's new revenue recognition standard. Furthermore, the ASU addresses other concems related to the current leases model; for example, eliminating the required use of bright-line tests in current GAAP for determining lease classification (operating leases versus capital leases). This ASU also includes enhanced disclosures surrounding leases. This ASU is effective for periods beginning on or after December 15, 2018; however, early adoption is permitted. The Company evaluated this standard and determined that it will not early adopt this standard as of December 31, 2015. Upon adoption, this ASU must be applied using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. The Company is evaluating this standard and cannot, at this time, estimate the potential impact on its future furancial condition, results of operations and cash flows. NOTE 3. BUSINESS ACQUISITIONS Alaska Energy and Resources Company On July 1,2014, the Company acquired AERC, based in Juneau, Alaska, and as of that date, AERC became a wholly-owned subsidiary of Avista Corp. The primary subsidiary of AERC is AEL&P, a regulated utility which provides electric services to approximately 17,000 customers in the City and Borough of Juneau (Juneau), Alaska as of December 3 I , 201 5. In addition to the regulated utility, AERC owns AJT Mining, which is an inactive mining company holding certain properties. The purpose of the acquisition was to expand and diversif Avista Corp.'s energy assets and deliver long-term value to its customers, communities and investors. In connection with the closing, on July I ,2014 Avista Corp. issued 4,500,0 l4 new shares of common stock to the shareholders of AERC based on a conkactual formula that resulted in a price of $32.46 per share, reflecting a purchase price of $170.0 million, plus acquired cash, less outstanding debt and other closing adjustments. The $32.46 price per share of Avista Corp. conunon stock was determined based on the average closing stock price of Avista Corp. corlmon stock for the I 0 consecutive trading days immediately preceding, but not including, the trading day prior to July l, 2014. This value was used solely for determining the number of shares to issue based on the adjusted contract closing price (see reconciliation below). The fair value of the consideration transferred at the closing date was based on the closing stock price of Avista Corp, common stock on July 1,2014, which was $33.35 per share. On October 1,2014, a working capital adjustment was made in accordance with the agreement and plan of merger which resulted in Avista Corp. issuing an additional 1,427 shares of common stock to the shareholders of AERC. The number of shares issued on October 1,2074 was based on the same contractual formula described above. The fair value of the new shares issued in October was $30.71 per share, which was the closing stock price of Avista Corp. common stock on that date. The contract acquisition price and the fair value of consideration hansferred for AERC were as follows (in thousands, except "per share" and number ofshares data): FERC FORM NO.2/3-Q 1 122.1'l Name of Respondent Avista Corporation This Report is: (1) X An OriginalQ\ A Resubmission Date of Report (Mo, Da, Yr) 04t1512016 Year/Period of Report 2015tQ4 Notes to Financial Statements Contract acquisition price (using the calculated $32.46 per share common stock price) Gross contract price Acquired cash Acquired debt (excluding capital lease obligation) Other closing adjustments (including the working capital adjustrnent) Total adjusted contract price Fair value of consideration transferred Avista Corp. common stock (4,500,014 shares at $33.35 per share) Avista Corp. common stock (1,427 shares at $30.71 per share) Cash Fair value oftotal consideration transferred Assets acquired: Current Assets: Cash Accounts receivable - gross totals S3,928 Materials and supplies Other current assets Total current assets Utility plant in service Utility properfy under long-term capital lease Construction work in progress Total utility property Other Non-current Assets: Non-utility property Electric plant held for future use Goodwill(1) Other deferred charges and non-current assets 170,000 19,704 (38,832) 37 1s0,909 154,911 The assets acquired and liabilities assumed related to the AERC transaction are not included in the FERC Balance Sheets. The information below is presented for information purposes only. The fair value of assets acquired and liabilities assumed as of July 1 , 2014 (after consideration of the working capital adjustrnent and the income tax true-ups during the second quarter of 201 5) were as follows (in thousands): July 1,2014 150,075 44 4,792 19,704 3,851 2,017 999 26,571 113,964 71,007 3,440 I 88,41 I 6,660 3,711 52,426 5,368 FERC FORM NO. 2/3-Q 1 't22.12 Name of Respondent Avista Corporation This Report is: (1) X An Original(2) A Resubmission Date of Report (Mo, Da, Yr) 04t15t2016 Year/Period of Report 2015tQ4 Notes to Financial Statements Total other non-current assets Total assets Liabilities Assumed: Current Liabilities: Accounts payable Current portion oflong-term debt and capital lease obligations Other current liabilities (l ) Total current liabilities Long-term debt Capital lease obligations Other non-current liabilities and deferred credits (l) Total liabilities Total net assets acquired 283,147 700 Jrl l) 2,80',7 7,280 37,227 68,840 14,889 128,236 154,91 r (l) During the second quarter of 2015, AEL&P recorded a reduction to goodwill of approximately $0.3 million due to income tax related adjustments. After consideration of the goodwill adjustment in the second quarter of 2015, the transaction resulted in a total amount of goodwill of $52.4 million. The goodwill associated with this acquisition is not deductible for tax purposes. The majority of AERC's operations are subject to the rate-setting authority of the RCA and are accounted for pursuant to GAAP, including the accounting guidance for regulated operations. The rate-setting and cost recovery provisions currently in place for AERC's regulated operations provide revenues derived from costs, including a return on investment, of assets and liabilities included in rate base. Due to this regulation, the fair values of AERC's assets and liabilities subject to these rate-setting provisions are assumed to approximate their carrying values. There were not any identifiable intangible assets associated with this acquisition. The excess of the purchase consideration over the estimated fair values of the assets acquired and liabilities assumed was recognized as goodwill at the acquisition date. The goodwill reflects the value paid for the expected continued growth of a rate-regulated business located in a defined service area with a constructive regulatory environment, the attractiveness of stable, growing cash flows, as well as providing a platform for potential future growth outside of the rate-regulated electric utility in Alaska and potential additional utility investment. NOTE 4. DISCONTINUED OPERATIONS On June 30,2014, Avista Capital, completed the sale of its interest in Ecova to Cofely USA Inc,, an indirect subsidiary of GDF SUEZ, a French multinational utility company, and an unrelated party to Avista Corp. The sales price was $335.0 million in cash, less the pa).rnent of debt and other customary closing adjustments. At the closing of the transaction on June 30,2074, Ecova became a wholly-owned subsidiary of Cofely USA Inc. and the Company has not had and will not have any further involvement with Ecova after such date. The purchase price of $335.0 million, as adjusted, was divided among the security holders of Ecova, including minority shareholders, option holders and a warrant holder, pro rata based on ownership. Approximately $ 16.8 million (5 percent of the purchase price) was held in escrow for l5 months from the closing of the transaction to satisfu certain indemnif,rcation obligations under the merger agreement (Escrow). An additional $1.0 million was held in escrow pending resolution of adjustments to working capital.

As expected, no claims were made against the Escrow as of September 30, 2015 (the end of the claims period) and accordingly, all Escrow amounts were released in October 201 5 and the Company received its full portion of the Escrow proceeds together with the remainder of the working capital adjustment escrow for a total amount of $13.8 million. After consideration of the escrow amounts received, the sales transaction provided cash proceeds to Avista Corp., net of debt, payment to option and minority holders, income taxes and transaction expenses, of $143.7 million and resulted in a net gain of $74.8 million. Almost all of the net gain was recognized in 2014 with some true-ups during 201 5. The summary of cash proceeds associated with the sales transaction are as follows (in thousands): Reconciliation of Gross Proceeds Contract price Closing adjustments Litigation settlement at Ecova Gross proceeds from sale (l) Cash sold in the transaction Gross proceeds from sale ofEcova, net ofcash sold (2) Reconciliation of total net proceeds Gross proceeds from sale (l) Repayment of long-term borrowings under committed line of credit Payment to option holders and redeemable noncontrolling interests Payment to noncontrolling interests Transaction expenses withheld from proceeds Net proceeds to Avista Capital (prior to tax payments) (2) Tax payments made in20l4 Tax payments made in 2015 Total net proceeds related to sales transaction 335,000 4,103 s88 339,691 (95,932) 243,759 339,691 (40,000) (20,871) (54,179) (5,461) 219,180 (74,842) (se0) 143,748 (l) Of this total amount, approximately $16.8 million was held in escrow for 15 months from the transaction closing date for any indemnity claims and an additional $1.0 million was held in escrow pending resolution of adjustments to working capital. Both of these escrow accounts were resolved during 2015. (2) Of the total gross proceeds and total net proceeds received, approximately $229.9 million and $205.4 million was received in 2014, respectively, with the remainder being received in 2015. NOTE 5. DERIVATIVES AND RISK MANAGEMENT E n e r gy Co mmo digt D eriv at ives Avista Corp. is exposed to market risks relating to changes in electricity and natural gas commodity prices and certain other fuel prices. FERC FORM NO. 2/3-Q (REV 12-07 122.14 Name of Respondent Avista Corporation This Report is: (1) X An OriginalQ\ A Resubmission Date of Report (Mo, Da, Yr) 04115t2016 Year/Period of Report 20151Q4 Notes to Financial Statements Market risk is, in general, the risk of fluctuation in the market price of the commodity being traded and is influenced primarily by supply and demand. Market risk includes the fluctuation in the market price of associated derivative commodity instruments. Avista Corp. utilizes derivative instruments, such as forwards, futures, swaps and options in order to manage the various risks relating to these commodity price exposures. The Company has an energy resources risk policy and control procedures to manage these risks. As part of the Company's resource procurement and management operations in the electric business, the Company engages in an ongoing process of resource optimization, which involves the economic selection from available energy resources to serve the Company's load obligations and the use of these resources to capture available economic value. The Company transacts in wholesale markets by selling and purchasing electric capacity and energy, fuel for electric generation, and derivative contracts related to capacity, energy and fuel. Such transactions are part of the process of matching resources with load obligations and hedging the related financial risks. These transactions range from terms of intra-hour up to multiple years. As part of its resource procurement and management of its natural gas business, Avista Corp. makes continuing projections of its natural gas loads and assesses available natural gas resources including natural gas storage availability. Natural gas resource planning typically includes peak requirements, low and average monthly requirements and delivery constraints from natural gas supply locations to Avista Corp.'s distribution system. However, daily variations in natural gas demand can be significantly different than monthly demand projections. On the basis of these projections, Avista Corp. plans and executes a series of transactions to hedge a portion of its projected natural gas requirements through forward market transactions and derivative instruments. These transactions may extend as much as four natural gas operating years (November through October) into the future. Avista Corp. also leaves a significant portion of its natural gas supply requirements unhedged for purchase in short-term and spot markets. The following table presents the underlying energy commodity derivative volumes as of December 3 1 , 20 I 5 that are expected to be settled in each respective year (in thousands of MWhs and mmBTUs): Purchases Electric Derivatives Physical (l) Financial (1) MWh MWh Gas Derivatives Electric Derivatives Gas Derivatives Physical (1) Financial (l) mmBTUs mmBTUs Physical (l) Financial (l) MWh MWh Physical (l) Financial (l) mmBTUs mmBTUsYear 2016 2017 20r8 2019 2020 Thereafter 407 1,954 397 97 397 235 17,252 142,693 280 675 49,200 255 l5,l 18 286 305 6,935 158 45s 905 2,656 3,182 112,233 483 1,360 26,965 1,360 2,738 1,345 1,430 1,060 (1) Physical transactions represent commodity transactions in which Avista Corp. will take or make delivery of either electricity or natural gas; financial transactions represent derivative instruments with delivery of cash in the amount of gain or loss but with no physical delivery of the commodity, such as futures, swaps, options, or forward contracts. The electric and natural gas derivative contracts above will be included in eitherpower supply costs or natural gas supply costs during the period they are settled and will be included in the various recovery mechanisms (ERM, PCA, and PGAs), or in the general rate case process, and are expected to be collected through retail rates from customers. Foreign Currency Exchange Contracls A significant portion of Avista Corp.'s natural gas supply (including fuel for power generation) is obtained from Canadian sources.

A portion of Avista Corp.'s short-term natural gas ffansactions and long-term Canadian transportation contracts are committed based on Canadian curency prices and settled within 60 days with U.S. dollars. Avista Corp. hedges a portion of the foreign currency risk by purchasing Canadian currency exchange contracts when such commodify transactions are initiated. This risk has not had a material effect on the Company's financial condition, results of operations or cash flows and these differences in cost related to currency fluctuations were included with natural gas supply costs for ratemaking.

The Company hedges a portion of its interest rate risk with financial derivative instruments, which may include interest rate swaps and U.S. Treasury lock agreements. These interest rate swaps and U.S. Treasury lock agreements are considered economic hedges against fluctuations in future cash flows associated with anticipated debt issuances.

The interest rate swap contracts were settled in connection with the pricing of $100.0 million of Avista Corp. first mortgage bonds that were issued in December 2015 (see Note l2). Upon settlement of interest rate swaps, the regulatory asset or liability is amortized as a component of interest expense over the term of the associated debt. The fair value of outstanding interest rate swaps can vary significantly from period to period depending on the total notional amount of swaps outstanding and fluctuations in market interest rates compared to the interest rates fixed by the swaps. The Company would be required to make cash payments to settle the interest rate swaps if the fixed rates are higher than prevailing market rates at the date of FERC FORM NO. 2/3-Q (REV 12-07 122.16 Name of Respondent Avista Corporation This Report is: (1) X An Original(2\ A Resubmission Date of Report (Mo, Da, Yr) o4t1st2016 Year/Period of Report 2015t44 Notes to Financial Statements settlement.

As a result, sudden and significant demands may be made against the Company's credit facilities and cash. The Company actively monitors the exposure to possible collateral calls and takes steps to mitigate capital requirements. The following table presents the Company's collateral outstanding related to its derivative instruments as of as of December 31 (in thousands): 201 5 20t4 Energy commodity derivatives Cash collateral posted Letters of credit outstanding Balance sheet offsetting (cash collateral against net derivative positions) Interest rate swaps Cash collateral posted Letters of credit outstanding Balance sheet offsetting (cash collateral against net derivative positions) 28,716 $ 28,200 14,526 34,030 9,600 34,030 20,565 14,500 I 5,5 10 28,880 10,900 28,880 Certain of the Company's derivative instruments contain provisions that require the Company to maintain an "investment grade" credit rating from the major credit rating agencies. If the Company's credit ratings were to fall below "investment grade," it would be in violation of these provisions, and the counterparties to the derivative instruments could request immediate payment or demand immediate and ongoing collateralization on derivative instruments in net liability positions.

The Company often extends credit to counterparties and customers and is exposed to the risk that it may not be able to collect amounts owed to the Company. Credit risk includes potential counterparty default due to circumstances: . relating directly to it, . saused by market price changes, and r relating to other market participants that have a direct or indirect relationship with such counterparty. Changes in market prices may dramatically alter the size of credit risk with counterparties, even when conservative credit limits are established. Should a counterparty fail to perform, tle Company may be required to honor the underlying commitrnent or to replace existing contracts with contracts at then-current market prices. The Company enters into bilateral transactions with various counterparties. The Company also transacts in enerry and related derivative insffuments through clearinghouse exchanges. In addition, the Company has concentrations of credit risk related to geographic location as it operates in the western United States and western Canada. These concentrations of counterparties and concentrations of geographic location may impact the Company's overall exposure to credit risk because the counterparties may be similarly affected by changes in conditions. The Company maintains credit support agreements with certain counterparties and margin calls are periodically made and/or received. Margin calls are triggered when exposures exceed contractual Iimits or when there are changes in a counterparty's creditworthiness. Price movements in electricity and natural gas can generate exposure levels in excess of these contractual limits. Negotiating for collateral in the form of cash, letters of credit, or performance guarantees is common indusky practice. NOTE 6. JOINTLY OWNED ELECTRIC FACILITIES The Company has a l5 percent ownership interest in a twin-unit coal-fired generating facility, Colship, located in southeastern Montana, and provides funancing for its ownership interest in the project. The Company's share of related fuel costs as well as operating expenses for plant in service are included in the corresponding accounts in the Statements of Income.

ASSET RETIREMENT OBLIGATIONS See Note I for a discussion of the Company's accounting policy associated with AROs. Specifically, the Company has recorded liabilities for future AROs to: (243,363) (239,845) . restore coal ash containment ponds at Colsffip, . cap a landfill at the Kettle Falls Plant, . remove plant and restore the land at the Coyote Springs 2 site at the termination of the land lease, and . dispose of PCBs in certain transformers. Due to an inability to estimate a range of settlement dates, the Company cannot estimate a liability for the: . removal and disposal of certain transmission and distribution assets, and o abandonment and decommissioning of certain hydroelectric generation and natural gas storage facilities. On April 17,2015, the EPA published a hnal rule regarding CCRs, also termed coal combustion byproducts or coal ash in the Federal Register and this rule became effective on October 15, 2015. Colship, of which Avista Corp. is a 15 percent owner of units 3 and 4, produces this byproduct. The rule establishes technical requirements for CCR landfills and surface impoundments urder Subtitle D of the Resource Conservation and Recovery Act, the nation's primary law for regulating solid waste. The Company, in conjunction with the other Colstrip owners, is developing a multi-year compliance plan to strategically address the new CCR requirements and existing State obligations while maintaining operational stability. During the second quarter of 20 I 5, the operator of Colstrip provided an initial cost estimate of the expected retirement costs associated with complying with the new CCR rule and this estimate was subsequently updated during the fourth quarter of 2015. Based on the initial assessments, Avista Corp. recorded an increase to its ARO of $12.5 million during 2015 with a corresponding increase in the cost basis of the utility plant. The actual asset retirement costs related to the new CCR rule requirements may vary substantially from the estimates used to record the increased obligation due to uncertainty about the compliance strategies that will be used and the preliminary nature of available data used to estimate costs, such as the quantity of coal ash present at certain sites and the volume of fill that will be needed to cap and cover certain impoundments. Avista Corp. will coordinate with the plant operator and continue to gather additional data in future periods to make decisions about compliance sffategies and the timing of closure activities. As additional information becomes available, Avista Corp. will update the ARO for these changes in estimates, which could be material. The Company expects to seek recovery of any increased costs related to complying with the new rule through customer rates.

PENSION PLANS AND OTHER POSTRETIREMENT BENEFIT PLANS The Company has a defined benefit pension plan covering the majority of all regular full-time employees at Avista Corp. that were hired prior to January 1,2014. Individual benefits under this plan are based upon the employee's years ofservice, date ofhire and average compensation as specified in the plan. Non-union employees hired on or after January 1,2014 participate in a defined contribution 40 I (k) plan in lieu of a defined benefit pension plan. The Company's funding policy is to contribute at least the minimum amounts that are required to be funded under the Employee Retirement Income Security Act, but not more than the maximum amounts that are currently deductible for income tax purposes. The Company contributed $12.0 million in cash to the pension plan in 2015, $32.0 million in2014 and $44.3 million in 2013. The Company expects to contribute $12.0 million in cash to the pension plan in 2016. The Company also has a SERP that provides additional pension benefits to executive officers and certain key employees of the Company. The SERP is intended to provide benefits to individuals whose benefits under the defined benefit pension plan are reduced due to the application of Section 4 I 5 of the Internal Revenue Code of I 986 and the deferral of salary under deferred compensation plans. The liability and expense for this plan are included as pension benefits in the tables included in this Note. The Company expects that benefit payments under the pension plan and the SERP will total (dollars in thousands): 20 l6 201'l 201 8 2019 2020 To1al202l-2025 Expected benefit payments $ 29,182 $30,260 $31,332 $32,804 $34,430 $189,919 The expected long-term rate ofretum on plan assets is based on past performance and economic forecasts for the types ofinvestments held by the plan. In selecting a discount rate, the Company considers yield rates for highly rated corporate bond portfolios with maturities similar to that of the expected term of pension benefits. The Company provides certain health care and life insurance benefits for eligible retired employees that were hired prior to January 1, 2014. The Company accrues the estimated cost of postretirement benefit obligations during the years that employees provide services. The liability and expense of this plan are included as other postretirement benefits. Non-union employees hired on or after January I , 2014, will have access to the retiree medical plan upon retirement; however, Avista Corp. will no longer provide a conhibution toward their medical premium. The Company has a Health Reimbursement Arrangement (HRA) to provide employees with tax-advantaged funds to pay for allowable medical expenses upon retirement, The amount earned by the employee is fixed on the retirement date based on the employee's years of service and the ending salary. The liability and expense of the HRA are included as other postretirement benefits. The Company provides death benefits to beneficiaries of executive offlrcers who die during their term of office or after retirement. Under the plan, an executive officer's designated beneficiary will receive a payment equal to twice the executive officer's annual base salary at the time of death (or if death occurs after retirement, a payment equal to twice the executive officer's total annual pension benefit). The liability and expense for this plan are included as other postretirement benefits.

The Company has conffacted with investment consultants who are responsible for managing/monitoring the individual investment managers. The investment managers' performance and related individual fund performance is periodically reviewed by an internal benefits committee and by the Finance Committee to monitor compliance with investment policy objectives and strategies. Pension plan assets are invested in mutual funds, trusts and partnerships that hold marketable debt and equity securities, real estate, absolute return and commodity funds. In seeking to obtain the desired return to fund the pension plan, the invesfment consultant recommends allocation percentages by asset classes. These recommendations are reviewed by the internal benefits committee, which then recommends their adoption by the Finance Committee. The Finance Committee has established target investment allocation percentages by asset classes and also investment ranges for each asset class. The target investment allocation percentages are typically the midpoint of the established range. The target investment allocation percentages by asset classes are indicated in the table below: 20ts 2014 27% 58% 6% 9o/o 27% 58% 6% 9% The fair value of pension plan assets invested in debt and equity securities was based primarily on fair value (market prices). The fair value ofinvestment securities traded on a national securities exchange is determined based on the reported last sales price; securities traded in the over-the-counter market are valued at the last reported bid price. Investment securities for which market prices are not readily available or for which market prices do not represent the value at the time of pricing, the investment manager estimates fair value based upon other inputs (including valuations of securities that are comparable in coupon, rating, maturity and industry). Investments in common/collective trust funds are presented at estimated fair value, which is determined based on the unit value of the fund. Unit value is determined by an independent trustee, which sponsors the fund, by dividing the fund's net assets by its units outstanding at the valuation date. The Company's investments in common/collective trusts have redemption limitations that permit quarterly redemptions following notice requirements of 45 to 60 days. The fair values of the closely held investments and partnership interests are based upon the allocated share ofthe fair value ofthe underlying assets as well as the allocated share ofthe undistributed profits and losses, including realized and unrealized gains and losses. Most of the Company's investments in closely held investments and partnership interests have redemption limitations that range from bi-monthly to semi-annually following redemption notice FERC FORM NO. 2/3-Q (REV 12-07)'t22.24 Name of Respondent Avista Corporation This Report is: (1) X An OriginalQ\ A Resubmission Date of Report (Mo, Da, Yr) 04t15t2016 Year/Period of Report 201510.4 Notes to Financial Statements requirements of 60 to 90 days. One investment in a partnership has a lock-up for redemption currently expiring in2022 and is subject to extension. The fair value of pension plan assets invested in real estate was determined by the investment manager based on three basic approaches: o properties are externally appraised on an annual basis by independent appraisers, additional appraisals may be performed as warranted by specific asset or market conditions, . property valuations are reviewed quarterly and adjusted as necessary, and o loans are reflected at fair value. The fair value of pension plan assets was determined as of December 3 I , 20 1 5 and 20 I 4. Effective December 3 1, 2015, the Company adopted ASU No. 2015-07, "Fair Value Measurement (Topic 820): Disclosures for Investrnents in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)," which removed from the fair value hierarchy, investments for which the practical expedient is used to measure fair value at net asset value (NAV). In prior years, the Company held investments fair valued using NAV and these amounts were included as level 3 items. This ASU was adopted retrospectively; therefore, the 2014 amounts have been reclassified to conform to the 2015 presentation. Also, since these amounts are no longer included in the fair value hierarchy as Ievel 3 items, the level 3 reconciliations are no longer applicable and have been excluded from this footnote.

The Company evaluated available evidence supporting the realization of its deferred income tax assets and determined it is more likely than not that deferred income tax assets will be realized. As of December 31, 2015, the Company had $15.3 million of state tax credit carryforwards of which it is expected $2.9 million will expire unused; the Company has reflected the net amount of $12.4 million as an asset at December 31, 2015. State tax credits expire from 2019 to2028. The Company and its eligible subsidiaries file consolidated federal income tax returns. The Company also files state income tax retums in certain jurisdictions, including Idaho, Oregon and Montana. Subsidiaries are charged or credited with the tax effects of their operations on a stand-alone basis. The Internal Revenue Service (IRS) has completed its examination of all tax years through 201 I and all issues were resolved related to these years. The IRS has not completed an examination of the Company's 2012 and2014 federal income tax returns. The Company believes that any open tax years for federal or state income taxes will not result in adjustments that would be significant to the financial statements.

As a result, these costs are recovered either through base retail rates or adjustments to retail rates as part ofthe power and natural gas cost deferral and recovery mechanisms. The above future contractual commitments for power resources include fixed contracfual amounts related to the Company's contracts with certain PUDs to purchase portions of the output of certain generating facilities. Although Avista Corp. has no investment in the PUD generating facilities, the fixed contracts obligate Avista Corp. to pay certain minimum amounts whether or not the facilities are operating. The cost of power obtained under the contracts, including payments made when a facility is not operating, is included in utility resource costs in the Statements of Income. The contractual amounts included above consist of Avista Corp.'s share of existing debt service cost and its proportionate share of the variable operating expenses of these projects. The minimum amounts payable under these contracts are based in part on the proportionate share of the debt service requirements of the PUD's revenue bonds for which the Company is indirectly responsible. The Company's total future debt service obligation associated with the revenue bonds outstanding at December 31,2015 (principal and interest) was $72.0 million. In addition, Avista Corp. has operating agreements, settlements and other contractual obligations related to its generating facilities and transmission and distribution services.

The Company has the option to request an extension for an additional one or two years beyond April 2019, provided, 1) that no event ofdefault has occurred and is continuing prior to the requested extension and 2) the remaining term ofagreement, including the requested extension period, does not exceed five years. The committed line of credit is secured by non-transferable first mortgage bonds of the Company issued to the agent bank that would only become due and payable in the event, and then only to the extent, that the Company defaults on its obligations under the committed line of credit. The committed line of credit agreement contains customary covenants and default provisions. The credit agreement has a covenant which does not permit the ratio of "consolidated total debt" to "consolidated total capitalization" of Avista Corp. to be greater than 65 percent at any time.

FAIR VALUE The carrying values ofcash and cash equivalents, special deposits, accounts and notes receivable, accounts payable and notes payable are reasonable estimates of their fair values. Bonds and advances from associated companies are reported at carrying value on the Balance Sheets. The fair value hierarchy prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level I measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The three levels of the fair value hierarchy are defined as follows: Level I - Quoted prices are available in active markets for identical assets or liabilities. Active markets are those in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2 - Pricing inputs are other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry-standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors, and current market and contractual prices for the underlying instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace throughout the full term of the instrument, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace. Level 3 - Pricing inputs include significant inputs that are generally unobservable from objective sources. These inputs may be used with internally developed methodologies that result in management's best estimate of fair value. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company's assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels. The determination of the fair values incorporates various factors that not only include the credit standing of the counterparties involved and the impact of credit enhancements (such as cash deposits and letters of credit), but also the impact of Avista Corp.'s nonperformance risk on its Iiabilities. The following table sets forth the carrying value and estimated fair value of the Company's financial instruments not reported at estimated fair value on the Balance Sheets as of December 3l (dollars in thousands): 201420r5 Carrying Value Estimated Fair Value Carrying Value Estimated Fair Value Bonds (Level 2) Bonds (Level 3) Advances from associated companies (Level 3) 951,000 $ 502,000 51,547 402,000 51,547 432,728 38,582 1,055,797 $ 505,768 36,083 95 t ,000 $ l,l 18,972 FERC FORM NO.2/3.Q 12-071 't22.32 Name of Respondent Avista Corporation This Report is: (1) X An OriginalQ\ A Resubmission Date of Report (Mo, Da, Yr) 04t15t2016 Year/Period of Report 2015tQ4 Notes to Financial Statements These estimates of fair value of long-term debt and long-term debt to affiliated ffusts were primarily based on available market information, which generally consists of estimated market prices from third parry brokers for debt with similar risk and terms. The price ranges obtained from the third party brokers consisted ofpar values of70.00 to I 19.70, where a par value of 100.00 represents the carrying value recorded on the Balance Sheets. Level2long-term debt represents publicly issued bonds with quoted market prices; however, due to their limited trading activity, they are classified as level 2 because brokers must generate quotes and make estimates if there is no trading activity near a period end. Level 3 long-term debt consists ofprivate placement bonds and Advances from associated companies, which typically have no secondary trading activity. Fair values in Level 3 are estimated based on market prices from third party brokers using secondary market quotes for debt with similar risk and terms to generate quotes for Avista Corp. bonds.

In addition, the Company nets derivative assets and derivative liabilities against any payables and receivables for cash collateral held or placed with these same counterparties. Avista Corp. enters into forward contracts to purchase or sell a specified amount of enerry at a specified time, or during a specified period, in the future. These contracts are entered into as part of Avista Corp.'s management of loads and resources and certain contracts are considered derivative instruments. The difference between the amount of derivative assets and liabilities disclosed in respective levels and the amount of derivative assets and liabilities disclosed on the Balance Sheets is due to netting arrangements with certain counterparties. The Company uses quoted market prices and forward price curves to estimate the fair value of utility derivative commodity instruments included in Level 2. In particular, electric derivative valuations are performed using market quotes, adjusted for periods in between quotable periods. Natural gas derivative valuations are estimated using New York Mercantile Exchange CNYMEX) pricing for similar instruments, adjusted for basin differences, using market quotes. Where observable inputs are available for substantially the full term of the contract, the derivative asset or liability is included in Level 2. FERC FORM NO. 2/3.Q (REV 1 122.34 Name of Respondent Avista Corporation This Report is: (1) X An OriginalQl A Resubmission Date of Report (Mo, Da, Yr) 04t15t2016 Year/Period of Report 2015tQ4 Notes to Financial Statements To establish fair values for interest rate swaps, the Company uses forward market curves for interest rates for the term of the swaps and discounts the cash flows back to present value using an appropriate discount rate. The discount rate is calculated by third party brokers according to the terms of the swap agreements and evaluated by the Company for reasonableness, with consideration given to the potential non-performance risk by the Company. Future cash flows of the interest rate swaps are equal to the fixed interest rate in the swap compared to the floating market interest rate multiplied by the notional amount for each period. To establish fair value for foreign currency derivatives, the Company uses forward market curves for Canadian dollars against the US dollar and multiplies the difference between the locked-in price and the market price by the notional amount of the derivative. Forward foreign currency market curyes are provided by third party brokers. The Company's credit spread is factored into the locked-in price of the foreign exchange contracts. Deferred compensation assets and liabilities represent funds held by the Company in a Rabbi Trust for an executive deferral plan. These funds consist of actively traded equity and bond funds with quoted prices in active markets. The balance disclosed in the table above excludes cash and cash equivalents of $0.6 million as of December 31, 2015 and $0.8 million as of December 31,2014. Level 3 Foir Value Under the power exchange agreement the Company purchases power at a price that is based on the on the average operating and maintenance (O&M) charges from three surrogate nuclear power plants around the country. To estimate the fair value of this agreement the Company estimates the difference between the purchase price based on the future O&M charges and forward prices for energy. The Company compares the Level 2 brokered quotes and forward price curves described above to an internally developed forward price which is based on the average O&M charges from the three surrogate nuclear power plants for the current year. Because the nuclear power plant O&M charges are only known for one year, all forward years are estimated assuming an annual escalation. In addition to the forward price being estimated using unobservable inputs, the Company also estimates the volumes of the hansactions that will take place in the future based on historical average transaction volumes per delivery year (November to April). Significant increases or decreases in any of these inputs in isolation would result in a significantly higher or lower fair value measurement. Generally, a change in the current year O&M charges for the surrogate plants is accompanied by a directionally similar change in O&M charges in future years. There is generally not a correlation between external market prices and the O&M charges used to develop the internal forward price. For the power commodity option agreement, the Company uses the Black-Scholes-Merton valuation model to estimate the fair value, and this model includes significant inputs not observable or corroborated in the market. These inputs include: I ) the strike price (which is an intemally derived price based on a combination of generation plant heat rate factors, natural gas market pricing, delivery and other O&M charges), 2) estimated delivery volumes, and 3) volatility rates for periods beyond January 201 8. Significant increases or decreases in any of these inputs in isolation would result in a significantly higher or lower fair value measurement. Generally, changes in overall commodity market prices and volatility rates are accompanied by directionally similar changes in the sfrike price and volatility assumptions used in the calculation. For the natural gas commodity exchange agreement, the Company uses the same Level 2 brokered quotes described above; however, the Company also estimates the purchase and sales volumes (within contractual limits) as well as the timing of those transactions. Changing the timing of volume estimates changes the timing of purchases and sales, impacting which brokered quote is used. Because the brokered quotes can vary significantly from period to period, the unobservable estimates of the timing and volume of transactions can have a significant impact on the calculated fair value. The Company currently estimates volumes and timing of transactions based on a most likely scenario using historical data.

COMMON STOCK The Company had a Direct Stock Purchase and Dividend Reinvesfrnent PIan under which the Company's shareholders could automatically reinvest their dividends and make optional cash payments for the purchase of the Company's common stock at current market value. This plan was terminated by the Company in 2014. The payment of dividends on common stock could be limited by: . certain covenants applicable to preferred stock (when outstanding) contained in the Company's Restated Articles of Incorporation, as amended (currently there are no preferred shares outstanding), . ceftain covenants applicable to the Company's outstanding long-term debt and committed line of credit agreements, o the hydroelectric licensing requirements of section l0(d) of the FPA (see Note l), and. . certain requirements under the Public Utility Commission of Oregon (OPUC) approval of the AERC acquisition. As of July I , 20 I 5 (one year following the acquisition date), the OPUC does not permit one-time or special dividends from AERC to Avista Corp. and does not permit Avista Corp.'s total equity to total capitalization to be less than 40 percent, without approval from the OPUC. However, the OPUC approval does allow for regular distributions of AERC earnings to Avista Corp. as long as AERC remains sufficiently capitalized and insured. The Company declared the following dividends for the year ended December 3l: 2015 2014 Dividends paid per common share $ 1.32 $ 1.27 FERC FORM NO. 2/3-O {REV 12-07 122.37 Name of Respondent Avista Corporation This Report is: (1) X An OriginalQ\ A Resubmission Date of Report (Mo, Da, Yr) o4115t2016 Year/Period of Report 2U5tA4 Notes to Financial Statements Under the covenant applicable to the Company's committed line of credit agreement, which does not permit the ratio of "consolidated total debt" to "consolidated total capitalization" to be greater than 65 percent at any time, the amount of retained earnings available for dividends at December 31, 2015 was limited to approximately $385.3 million. Under the requirements of the OPUC approval of the AERC acquisition as outlined above, the amount available for dividends at December 3 I , 201 5 was limited to approximately $23 1 .0 million. The Company has l0 million authorized shares of preferred stock. The Company did not have any preferred stock outstanding as of December 3 l, 201 5 and 2014. Stock Repurchase Programs During 2014, Avista Corp.'s Board of Directors approved a program to repurchase up to 4 million shares of the Company's outstanding cornmon stock (2014 program). Repurchases of common stock under this program began on July 7, 2014 and the program expired on December 31,2014. Repurchases were made in the open market or in privately negotiated transactions. Under the 2014 program the Company repurchased 2,529,615 shares at a total cost of $79.9 million and an average cost of $3 1.57 per share. The Company did not make any repurchases under this program subsequent to October 20 I 4. Avista Corp. initiated a second stock repurchase program on January 2,2015 that expired on March 31, 2015 for the repurchase of up to 800,000 shares of the Company's outstanding common stock (frst quarter 2015 program). The number of shares repurchased through the first quarter 201 5 program was in addition to the number of shares repurchased under t}te 2014 program, which expired on December 31,2014. Under the first quarler 2015 program, the Company repurchased 89,400 shares at a total cost of $2.9 million and an average cost of$32.66 per share. All repurchased shares under the 2014 program and the frst quarter 2015 program reverted to the status ofauthorized but unissued shares. NOTE 16. COMMITMENTS AND CONTINGENCTES In the course of its business, the Company becomes involved in various claims, controversies, disputes and other contingent matters, including the items described in this Note. Some of these claims, controversies, disputes and other contingent matters involve litigation or other contested proceedings. For all such matters, the Company intends to vigorously protect and defend its interests and pursue its rights. However, no assurance can be given as to the ultimate outcome of any particular matter because Iitigation and other contested proceedings are inherently subject to numerous uncertainties. For matters that affect Avista Corp.'s operations, the Company intends to seek, to the extent appropriate, recovery ofincurred costs through the ratemaking process. C al ifo r n ia Refund Pro c ee ding Recently, APX, a market maker in these proceedings in whose markets Avista Energy participated in the summer of 2000, has asserted that Avista Energy and its other customer/participants may be responsible for a share of the disgorgement penalty APX may be found to owe to the California parties. The penalty arises as a result of the FERC finding that APX committed violations in the Califomia market in the summer of 2000. APX is making these assertions despite Avista Energy having been dismissed in FERC Opinion No. 536 from the on-going administrative proceeding at the FERC regarding potential wrongdoing in the Califomia markets in the summer of 2000. APX has identified Avista Energy's share of APX's exposure to be as much as $16.0 million even though no wrongdoing allegations are specifically attributable to Avista Energy. Avista Enerry believes its settlement insulates it from any such liability and that as a dismissed party it.cannot be drawn back into the litigation. Avista Energy intends to vigorously dispute APX's assertions of indirect liability, but cannot at this time predict the eventual outcome. FERC FORM NO. 2/3.Q (REV 12.07)122.38 Name of Respondent Avista Corooration This Report is: (1) X An Original(2\ A Resubmission Date of Report (Mo, Da, Yr) 04t15t2016 Year/Period of Report 2015t44 Notes to Financial Statements Pacific No rtlrw est Refund Proceeding In July 2001, the FERC initiated a preliminary evidentiary hearing to develop a factual record as to whether prices for spot market sales of wholesale energy in the Pacific Northwest between December 25,2000 and June 20,2001 were just and reasonable. In June 2003, the FERC terminated the Pacific Northwest refund proceedings, after flurding that the equities do not justify the imposition of refunds. In August 2007 , the Ninth Circuit found that the FERC had failed to take into account new evidence of market manipulation and that such failure was arbitrary and capricious and, accordingly, remanded the case to the FERC, stating that the FERC's findings must be reevaluated in light of the new evidence. The Ninth Circuit expressly declined to direct the FERC to grant refunds. On October 3,2011, the FERC issued an Order on Remand. On April 5, 2013, the FERC issued an Order on Rehearing expanding the temporal scope of the proceeding to permit parties to submit evidence on transactions during the period from January 1, 2000 through and including June 20, 2001 . The Order on Remand established an evidentiary, trial-type hearing before an ALJ, and reopened the record to permit parties to present evidence of unlawful market activity. The Order on Remand stated that parties seeking refunds must submit evidence demonstrating that specific unlawful market activity occurred, and must demonstate that such activity directly affected negotiations with respect to the specific contract rate about which they complain. Simply alleging a general link between the dysfunctional spot market in California and the Pacihc Northwest spot market would not be sufficient to establish a causal connection between a particular seller's alleged unlawful activities and the specific contract negotiations at issue. The hearing was conducted in August through October 201 3. On July 11,2012 and March 28,2013, Avista Energy and Avista Corp. filed settlements of all issues in this docket with regard to the claims made by the City of Tacoma and the California AG (on behalf of CERS). The FERC has approved the settlements and they are final. The remaining direct claimant against Avista Corp. and Avista Energy in this proceeding is the City of Seattle, Washington (Seattle). With regard to the Seattle claims, on March 28,2014, the Presiding ALJ issued her Initial Decision finding that: l) Seattle failed to demonstrate that either Avista Corp. or Avista Energy engaged in unlawful market activity and also failed to identifr any specific contracts at issue; 2) Seattle failed to demonstrate that contracts with either Avista Corp. or Avista Energy imposed an excessive burden on consumers or seriously harmed the public interest; and that 3) Seattle failed to demonstrate that either Avista Corp. or Avista Energy engaged in any specific violations of substantive provisions of the FPA or any filed tariffs or rate schedules. Accordingly, the ALJ denied all of Seattle's claims under both section 206 and section 309 of the FPA. On May 22,2015, the FERC issued its Order on Initial Decision in which it upheld the ALJ's Initial Decision denying all of Seattle's claims against Avista Corp. and Avista Energy. Seattle filed a Request for Rehearing of the FERC's Order on Initial Decision which was denied on December 31, 2015. Seattle appealed the FERC's decision to the Ninth Circuit. The Company does not expect that this matter will have a material adverse effect on its financial condition, results of operations or cash flows. Sierrs CIub and Montana Environmental Information Center Complaint Against the Owners of Colstrip On March 6,2013, the Sierra Club and Montana Environmental Information Center (MEIC) (collectively "Plaintiffs"), filed a Complaint in the United States District Court for the District of Montana, Billings Division, against the Owners of the Colstrip Generating Project ("Colstrip"). Avista Corp. owns a l5 percent interest in Units 3 & 4 of Colstrip. The other Colstrip co-Owners are Talen (formerly PPL Montana), Puget Sound Energy, Portland General Elechic Company, NorthWestern Energy and PacifiCorp. The Complaint alleges certain violations of the Clean Air Act, including the New Source Review, Title V and opacity requirements. On September 27,2013, the Plaintiffs filed an Amended Complaint. The Amended Complaint withdrew from the original Complaint fifteen claims related to seven pre-January 1, 2001 Colstrip maintenance projects, upgrade projects and work projects and claims alleging violations of Title V and opacity requirements. The Amended Complaint alleges certain violations of the Clean Air Act and the New Source Review and adds claims with respect to post-January l, 2001 Colstrip projects. On August 27,2014, the Plaintiffs filed a Second Amended Complaint. The Second Amended Complaint withdraws from the FERC FORM NO.2/3-Q 1 122.39 Name of Respondent Avista Corporation This Report is: (1) X An Original(2\ A Resubmission Date of Report (Mo, Da, Yr) 04115t2016 Year/Period of Report 2015tQ4 Notes to Financial Statements Amended Complaint five claims and adds one new claim. The Second Amended Complaint alleges certain violations of the Clean Air Act and the New Source Review. The Plaintiffs request that the Court grant injunctive and declaratory relief, order remediation of alleged environmental damages, impose civil penalties, require a beneficial environmental project in the areas affected by the alleged air pollution and require payment of Plaintiffs' costs of litigation and attorney fees. The Plaintiffs have since indicated that they do not intend to pursue two of the seven projects, leaving a total of five projects remaining. A number of motions for summary judgment were filed by both the Plaintiffs and the defendants. The Court issued its rulings on these motions and, as a result, only two projects remain for trial. The Plaintiffs have filed objections to the order. The case has been bifurcated into separate liability and remedy trials. The Court has set the liability trial date for May 3 I , 2016. No date has been set for the remedy trial. Management believes that it is reasonably possible that this matter could result in a loss to the Company. However, due to uncertainties conceming this matter, Avista Corp. cannot predict the outcome or determine whether it would have a material impact on the Company. Cobinel Gorge Total Dissolved Gas Abstemenl Plsn Dissolved atmospheric gas levels (referred to as "TDG") in the Clark Fork River exceed state of Idaho and federal water quality numeric standards downstream of Cabinet Gorge during periods when excess river flows must be diverted over the spillway. Under the terms of the Clark Fork Settlement Agreement as incorporated in Avista Corp.'s FERC license for the Clark Fork Project, Avista Corp. has worked in consultation with agencies, tribes and other stakeholders to address this issue. Under the terms of a gas supersaturation mitigation plan, Avista is reducing TDG by constructing spill crest modifications on spill gates at the dam, and the Company expects to continue spill crest modifications over the next several years, in ongoing consultation with key stakeholders. Avista Corp. cannot at this time predict the outcome or estimate a range of costs associated with this contingency; however, the Company will continue to seek recovery, through the ratemaking process, of all operating and capitalized costs related to this issue. Fish Passage at Cabinet Gorge snd Noxon Ropids In 1999, the United States Fish and Wildlife Service (USFWS) Iisted bull trout as threatened under the Endangered Species Act. In 2010, the USFWS issued a revised designation of critical habitat for bull trout, which includes the lower Clark Fork River. The USFWS issued a final recovery plan in October 2015. The Clark Fork Settlement Agreement describes programs intended to help restore bull trout populations in the project area. Using the concept of adaptive management and working closely with the USFWS, the Company evaluated the feasibility of fish passage at Cabinet Gorge and Noxon Rapids. The results of these studies led, in part, to the decision to move forward with development of permanent facilities, among other bull hout enhancement efforts. Fishway designs for Cabinet Gorge have been completed, and the Company is developing construction cost estimates currently. The Company believes its ongoing efforts through the Clark Fork Settlement Agreement continue to effectively address issues related to bull trout. Avista Corp. cannot at this time predict the outcome or estimate a range of costs associated with this contingency; however, the Company will continue to seek recovery, through the ratemaking process, of all operating and capitalized costs related to fish passage at Cabinet Gorge and Noxon Rapids. Co I lective B ar g ain in g A g r eemenls The Company's collective bargaining agreements with the IBEW represents approximately 45 percent of all of Avista Corp.'s employees. The agreement with the local union in Washington and Idaho representing the majority (approximately 90 percent) of the Avista Corp.'s bargaining unit employees expires in March 2016. In October 2015, a new collective bargaining agreement concerning wages over the three-year period 20 l6 through 20 I 8 was approved by the local IBEW in Washington and Idaho. The new collective bargaining agreement will be effective in March 2016. A three-year agreement in Oregon, which covers approximately 50 employees, expires in March 2017. FERC FORM NO. 2/3-Q (REV 1 122.40 Name of Respondent Avista Corporation This Report is: (1) X An Original(2\ A Resubmission Date of Report (Mo, Da, Yr) 04115t2016 Year/Period of Report 2U5tA4 Notes to Financial Statements There is a risk that if collective bargaining agreements expire and new agreements are not reached in each of our jurisdictions, employees could strike. Given the magnitude of employees that are covered by collective bargaining agreements, this could result in disruptions of our operations. However, the Company believes that the possibility of this occurring is remote. Customer Information and lilork Management Systems Project Cosl Recovery Over the past four years, Avista Corp. has invested significant capital into Project Compass. Project Compass was completed and went into service during the frst quarter of 2015. As part of the Washington electric and natural gas general rate cases filed in February 2015 and the Oregon natural gas general rate case filed in May 2015, Avista Corp. requested the full recovery of the Washington and Oregon share of the costs associated with this project. On July 27 ,2075, the UTC Staff in the Company's electric and natural gas general rate cases filed responsive testimony. Included in their testimony was a recommendation to disallow $12.7 million (Washington's share) of Project Compass costs primarily related to the delay in the completion of the project. In a UTC order received in January 2016, the UTC approved the full recovery of Washington's share of Project Compass costs with no disallowances. In October 20 I 5, the OPUC staff filed testimony in the Company's natural gas general rate case which included a recommendation to disallow $ I .2 million (Oregon's share) of Project Compass costs, similar to the initial recommendation in Washington. In an OPUC order received in February 2016, the OPUC approved the full recovery of Oregon's portion of Project Compass costs, with no disallowances. Other Contingencies In the normal course of business, the Company has various other legal claims and contingent mafiers outstanding. The Company believes that any ultimate liability arising from these actions will not have a material impact on its financial condition, results of operations or cash flows. It is possible that a change could occur in the Company's estimates of the probability or amount of a liability being incurred. Such a change, should it occur, could be significant. The Company routinely assesses, based on studies, expert analyses and legal reviews, its contingencies, obligations and commitments for remediation of contaminated sites, including assessments of ranges and probabilities of recoveries from other responsible parties who either have or have not agreed to a settlement as well as recoveries from insurance carriers. The Company's policy is to accrue and charge to current expense identified exposures related to environmental remediation sites based on estimates of investigation, cleanup and monitoring costs to be incurred. For maffers that affect Avista Corp.'s or AEL&P's operations, the Company seeks, to the extent appropriate, recovery ofincurred costs through the ratemaking process. The Company has potential liabilities under the Endangered Species Act for species of fish, plants and wildlife that have either already been added to the endangered species list, listed as "threatened" or petitioned for listing. Thus far, measures adopted and implemented have had minimal impact on the Company. However, the Company will continue to seek recovery, through the ratemaking process, of all operating and capitalized costs related to these issues. Under the federal licenses for its hydroelectric projects, the Company is obligated to protect its property rights, including water rights. In addition, the company holds additional non-hydro water rights. The state of Montana is examining the status of all water right claims within state boundaries through a general adjudication, Claims within the Clark Fork River basin could adversely affect the energy production of the Company's Cabinet Gorge and Noxon Rapids hydroelectric facilities. The state of Idaho has initiated adjudication in northern Idaho, which will ultimately include the lower Clark Fork River, the Spokane River and the Coeur d'Alene basin. The Company is and will continue to be a participant in these and any other relevant adjudication processes. The complexity of such adjudications makes each unlikely to be concluded in the foreseeable future. As such, it is not possible for the Company to estimate the FERC FORM NO. 2/3.Q (REV 12-07 122.41 Name of Respondent Avista Corooration This Report is: (1) X An OriginalQ\ A Resubmission Date of Report (Mo, Da, Yr) 04t1512016 Year/Period of Report 2015tQ4 Notes to Financial Statements impact of any outcome at this time. The Company will continue to seek recovery, through the ratemaking process, of all operating and capitalized costs related to this issue. NOTE I7. REGULATORY MATTERS Power Cost Deferrals and Recovery Mechanisms Deferred power supply costs are recorded as a deferred charge on the Balance Sheets for future prudence review and recovery through retail rates. The power supply costs deferred include certain differences between actual net power supply costs incurred by Avista Corp. and the costs included in base retail rates. This difference in net power supply costs primarily results from changes in: . short-term wholesale market prices and sales and purchase volumes, . the level and availability of hydroelectric generation, . the level and availability of thermal generation (including changes in fuel prices), and r retail loads. In Washington, the ERM allows Avista Corp. to periodically increase or decrease electric rates with UTC approval to reflect changes in power supply costs. The ERM is an accounting method used to track certain differences between actual power supply costs, net of wholesale sales and sales of fuel, and the amount included in base retail rates for Washington customers. Total net deferred power costs under the ERM were a liability of $18.0 million as of December 31,2015 compared to a liability of $14.2 million as of December 31, 2014, and these deferred power cost balances represent amounts due to customers. Avista Corp. has a PCA mechanism in Idaho that allows it to modiff electric rates on October I of each year with IPUC approval. Under the PCA mechanism, Avista Corp. defers 90 percent of the difference between certain actual net power supply expenses and the amount included in base retail rates for its Idaho customers. These annual October I rate adjustments recover or rebate power costs deferred during the preceding July-June twelve-month period. Total net power supply costs deferred under the PCA mechanism were a regulatory asset of $0.2 million as of December 31, 2015 compared to a regulatory asset of $8.3 million as of December 31,2014. Natural Gas Cost Deferrols and Recovery Mecltunisms Avista Corp. files a PGA in all three states it serves to adjust natural gas rates for: l) estimated commodity and pipeline transportation costs to serve natural gas customers for the coming year, and 2) the difference between actual and estimated commodity and transportation costs for the prior year. Total net deferred natural gas costs to be refunded to customers were a liability of $ I 7.9 million as of December 31,2015 compared to a liability of $3.9 million as of December 31,2014. Decoupling and Earnings Sharing Mechanisms Decoupling is a mechanism designed to sever the link between a utility's revenues and consumers' energy usage. The Company's actual revenue, based on kilowatt hour and therm sales will vary, up or down, from the level included in a general rate case, which could be caused by changes in weather, energy conservation or the economy. Generally, the Company's electric and natural gas revenues will be adjusted each month to be based on the number of customers, rather than kilowatt hour and therm sales. The difference between revenues based on sales and revenues based on the number ofcustomers will be deferred and either surcharged or rebated to customers beginning in the following year. llashington Decoupling and Earnings Sharing In Washington, the UTC approved the Company's decoupling mechanisms for electric and natural gas for a five-year period that commenced January l, 2015. Electric and natural gas decoupling surcharge rate adjustments to customers are limited to 3 percent on an annual basis, with any remaining surcharge balance carried forward for recovery in a future period. There is no limit on the level of FERC FORM NO.2/3.Q 12-07 122.42 Name of Respondent Avista Corporation This Report is: (1) X An OriginalQ\ A Resubmission Date of Report (Mo, Da, Yr) 04115t20',t6 Year/Period of Report 2015tQ4 Notes to Financial Statements rebate rate adjustments. The decoupling mechanisms each include an after-the-fact earnings test. At the end ofeach calendar year, separate electric and natural gas earnings calculations will be made for the prior calendar year. These earnings tests will reflect actual decoupled revenues, normalized power supply costs and other normalizing adjustnents. As of December 31, 2015, the Company had a total net decoupling surcharge (asset) of $10.9 million for WashinSon elechic and natural gas customers and a liability (rebate to customers) for earnings sharing of $3.4 million for Washington electric customers. Idaho Fixed Cost Adjustment (FCA) and Earnings Sharing Mechanisms In ldaho, the IPUC approved the implementation of FCAs for electric and natural gas (similar in operation and effect to the Washington decoupling mechanisms) for an initial term of three years, cornmencing on January 1,2016. For the period 2013 through 2015, the Company had an after-the-fact eamings test, such that if Avista Corp., on a consolidated basis for electric and natural gas operations in Idaho, eamed more than a 9.8 percent ROE, the Company was required to share with customers 50 percent of any earnings above the 9.8 percent. There was no provision for a surcharge to customers if the Company's ROE was less than 9.8 percent. This after-the-fact earnings test was discontinued as part of the settlement of the Company's 2015 Idaho electric and natural gas general rates cases. As of December 3 I , 201 5 and December 31,2014, the Company had total cumulative earnings sharing liabilities (rebates to customers) of $8.8 million and $10.1 million, respectively for electric and natural gas customers.

For each construction overhead explain: (a) the nature and extent of work, etc., the overhead charges are intended to cover, (b) the general procedure for determining the amount capitalized, (c) the method of distribution to construction jobs, (d) whether different rates are applied to different types of construction, (e) basis of differentiation in rates for different types of construction, and (0 whether the overhead is directly or indirectly assigned.2. Show below the computation of allowance for funds used during construction rates, in accordance with the provisions of Gas Plant lnstructions 3 (17) ofthe Uniform System ofAccounts. 3. Where a net-of-tax rate for borrowed funds is used, show the appropriate tax effect adjustment to the computations below in a manner that clearly indicates the amount of reduction in the gross rate for tax effects. Construction costs with a direct relationship to new construction and capital replacement activities that cannot be clearly identified with specific projects are charged to overhead pools. The established pools are:. Construction Overhead North Gas. Construction Overhead South Gas Pool costs are allocated monthly to gas construction projects on a percent rate applied to direct project costs, excluding AFUDC. Each pool's rate is calculated separately and applied only to the related gas construction projects for allocation. Allowance for funds used during construction is calculated system wide using a rate that is equivalent to the allowed rate of return approved in the latest rate order from the company's primary state commission (Washington State). For 2015, Avista used a rate of 7.32%, which is the allowed Rate of Return contained in the Washington Utilities Transportation Commission Final Order 05 date August 18,2014 for consolidated Dockets UE-140188 and UG-140189.
