Loans under this agreement were unsecured and had a variable annual interest rate. The Company borrowed the entire $70.0 million available under this agreement, which was used to repay a portion of the $90.0 million in first mortgage bonds that matured in August2016. This term loan was subsequently repaid in full in December using the proceeds from the first mortgage bonds issued in December 2016 (discussed below). In December 2016, Avista Corp. issued and sold $175.0 million of 3.54 percent first mortgage bonds due in 2051 pursuant to a bond purchase agreement with institutional investors in the private placement market. The total net proceeds from the sale of the bonds were used to repay the $70.0 million term loan discussed above and to repay a portion of the borrowings outstanding under the Company's $400.0 million committed line of credit. In connection with the execution of the bond purchase agreement, the Company cash-settled seven interest rate swap derivatives (notional aggregate amount of $125.0 million) and paid a total of $54.0 million. The debt issuance was approved by regulatory commissions as follows: UTC (Docket No. UE-151822 Order 01) IPUC (Case No. AVU-U- l5-01 Order No. 33401) and the OPUC (Docket W 4294 Order No. l5-305). 7.

Washington General Rate Cases 2015 General Rate Cases In January 2016, we received an order (Order 05) that concluded our 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 are designed to provide a 1.6 percent, or $8.1 million decrease in electric base revenue, and a7.4 percent, or $10.8 million increase in natural gas base revenue. The UTC also approved an rate of retum on rate base (ROR) of 7.29 percent, with a common equity ratio of 48.5 percent and a 9.5 percent retum on equity (ROE).

In the Motion for Clarification, ICNU and PC requested that the UTC clariff 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 Stafl which is a separate party in the general rate case proceedings from the UTC Advisory Staff, filed a Motion to Reconsider with the UTC. In 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 Stafffiled a Motion to Reopen Record for the Limited Purpose of Receiving into Evidence Instruction on Use and Application of Stafls 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 $10.8 million. On February 19,2016, the UTC issued an order (Order 06) denying the Motions summarized above and affirmed Order 05 including an $8.1 million decrease in electric base revenue. FERC FORM NO.2 108.3 Name of Respondent Avista Corporation This Report is: (1) X An Originale\ A Resubmission Date of Report (Mo, Da, Yr) 03t31t2017 Year/Period of Report 2016/Q4 lmportant Changes During the Quarter/Year PC Petitionfor Judicial Review On March 18,2016, PC filed in Thurston County Superior Court a Petition for Judicial Review of the UTC's Order 05 and Order 06 described above that concluded our 2015 electric and natural gas general rate cases. In its 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 our 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 our electric operations after finding that the we did not meet the newly articulated standard regarding attrition adjustments; (3) the UTC erred in applying the "end results test" to set rates for our electric operations that are not supported by the record; (4) the UTC did not correct its calculation of our electric rates after significant errors were brought to its attention; and (5) the UTC's calculation of our electric rates lacks substantial evidence. PC is requesting that the Court (l) vacate or set aside portions of the UTC's orders; (2) identifu the errors contained in the UTC's orders; (3) find that the rates approved in Order 05 and reaffrrmed 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 our revenue requirement for electric and natural gas services; and (5) find the customers are entitled to a refund. On April 18,2016, PC filed an application with the Thurston County Superior Court to certify this matter for review directly by the Court of Appeals, an intermediate appellate court in the State of Washington. After briefing and argument, the matter was certified on April 29,2016 and accepted by the Court of Appeals on July 29,2016. The parties are providing briefs to the Court, after which the Court will set the matter for argument. A decision from the Court is not expected until late 2017, at the earliest. The new rates established by Order 05 will continue in effect while the Petition for Judicial Review is being considered. We believe the UTC's Order 05 and Order 06 finalizing the electric and natural gas general rate 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 us with a reasonable opportunity to eam the rate of retum authorized by the UTC. 2016 General Rate Cases On December 15, 2016, the UTC issued an order related to our Washington electric and natural gas general rate cases that were originally filed with the UTC in February 2016. The UTC order denied the Company's proposed electric and natural gas rate increase requests of $38.6 million and $4.4 million, respectively. Accordingly, our current electric and natural gas retail rates will remain unchanged in Washington State. FERC FORM NO. 2 108.4 Name of Respondent Avista Corporation This Report is: (1) X An Original(21 A Resubmission Date of Report (Mo, Da, Yr) 03t31t2017 Year/Period of Report 2016tQ4 lmportant Changes During the Quarter/Year Our original requests were based on a proposed ROR of 7.64 percent with a common equity ratio of 48.5 percent and a9.9 percent ROE. On December 23,2016 we filed a Petition for Reconsideration or, in the alternative, Rehearing (Petition) with the UTC related to our 2016 general rate cases. The UTC's Order and Avista Corp.'s Response The primary reason given by the UTC in reaching its conclusion is that, in our request, we did not follow an "appropriate methodology" to show the existence of attrition, as between historical data and current and projected data. Further, the order states that, among other things, we did not demonstrate, as a necessary condition to being allowed an attrition adjustment, that we have suffered from chronic under-earning caused by circumstances beyond our ability to control. We disagree with the UTC as to various questions of fact and law. In support of its decision, the UTC stated that we did not demonstrate that our current revenue is insuffrcient for covering costs and providing the opportunity to earn a reasonable return during the 2017 rate period. The UTC also stated that we did not demonstrate that our capital expenditures and increased operating costs are both necessary and immediate. Our Petition responding to the UTC's order points to evidence in the case that demonstrates, contrary to the UTC's findings, the following: o Current retail rates are not sufficient for the 2077 rate period, and therefore a revenue increase is necessary. In previously filed testimony, UTC Staffagreed that current rates were not sufficient. o The costs associated with the growth in rate base and operating expenses are growing at a faster pace than revenue from retail sales, and therefore a revenue adjustment is necessary to close this gap. The revenue adjustment to close this gap is sometimes called an attrition adjustment. In previously filed testimony, UTC Staffagreed that a revenue adjustment is necessary to close this gap. o All of the capital projects and operating expenses we included in the case are necessary in the time frame proposed in order for us to continue to provide safe, reliable service to customers. No party in the case identified a single capital project that should not be completed in the time frame we proposed (other than Public Counsel's general opposition to Advanced Metering Infrastructure). o We presented all of the studies and analyses in this case, consistent with our previous filings with the UTC, and the UTC Staff acknowledged in previously filed testimony, that we provided such studies. o We eamed close to our allowed retum on equity during each of the years 2013 through 2015, and into 2016. This opportunity was possible only with the revenue increases related to attrition adjustments, and an attrition adjustment is also necessary for 2017. FERC FORM NO.2 108.5 Name of Respondent Avista Corporation This Report is: (1) X An Originale\ A Resubmission Date of Report (Mo, Da, Yr) 03t3'U2017 Year/Period of Report 2016/Q4 lmportant Changes During the Quarter/Year In previously filed testimony, the UTC Staff supported electric and natural gas revenue increases totaling $28.4 million. Commissioner Jones dissented and did not support the decision. In his dissent, Commissioner Jones supported an electric revenue increase of $26.0 million, and a natural gas increase of $2.4 million, based on UTC Staffs analysis. On February 27,2017, we received an order from the UTC denying our Petition and the UTC confirmed its previous order in the case. In its order denying the Petition, the UTC generally referred back to its prior findings and conclusions. Consistent with the original order, Commissioner Jones dissented and did not support the decision in the latest order. We evaluated all options for appeal of the Commission's latest order and determined that appeal of the Commission's decision to the courts would bring a significant amount of uncertainty regarding the level of success of such an appeal, as well as the timing of any value that might come following a process that would take between one and two years. The Company believes greater long-term value can be achieved through focusing on upcoming new general rate cases, than through appealing the recent decision in the courts. Now that the 2016 case is concluded, we will request meetings with the Commissioners to better understand their concerns and their expectations going forward. The Company will also reach out to Commission Staff and other parties to discuss needs and expectations prior to filing the next general rate case. The Company plans to file a general rate case in the second quarter of 2017. Idoho General Rate Cases 2015 General Rate Cases In December 2015, the IPUC approved a settlement agreement between Avista Utilities and all interested parties related to our electric and natural gas general rate cases, which were originally filed with the IPUC on June 1, 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 an ROR of 7.42 percent with a common equity ratio of 50 percent and a9.5 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 of the settlement of our 2012 electic and natural gas general rate cases, and o the implementation of electric and natural gas Fixed Cost Adjustment mechanisms, as discussed below. FERC FORM NO.2 (12-96)108.6 Name of Respondent Avista Corporation This Report is: (1) X An OriginalQ\ A Resubmission Date of Report (Mo, Da, Yr) 03t31t2017 Year/Period of Report 20161Q4 lmportant Ghanges During the Quarter/Year 2016 General Rate Cases In December 2016, the IPUC approved a settlement agreement between us and other parties in our electric general rate case, concluding our Idaho electric general rate case originally filed in May 2016. New rates took eflect on January l,20ll under the settlement agreement. We did not file a natural gas general rate case in 2016. The settlement agreement increases annual electric base rates by 2.6 percent (designed to increase annual electric revenues by $6.3 million). The settlement revenue increase is based on a ROR of 7.58 percent with a common equity ratio of 50 percent and a 9.5 percent ROE. In addition to the agreed upon increase in electric revenues to recover costs primarily driven by our increased capital investments in infrastructure to serve customers, the settlement agreement includes the continued recovery of approximately $4.1 million in costs related to the Palouse Wind Project through the PCA mechanism rather than through base rates. In our original request we requested an overall increase in base electric rates of 6.3 percent (designed to increase annual electric revenues by $15.a million), effective January 1,2017. Our original request was based on a proposed ROR of 7 .78 percent with a cornmon equity ratio of 50 percent and a9.9 percent ROE. Oregon General Rate Cases 2014 General Rate Cose In March 2015, we filed an all-party settlement agreement with the OPUC related to our natural gas general rate case, which was originally filed in September 2014. The 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 were 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 16,2015. On April 9, 2015, the OPUC issued an Order approving the sefflement 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 a preliminary order (and a final order on March 15,2016) concluding our 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 OPUC order provided an authorized ROR of 7.46 percent with a common equity ratio of 50 percent and a 9.4 percent ROE. The November 2015 partial settlement agreement, approved by the OPUC, included a provision for the implementation of a decoupling mechanism, similar to the Washington and Idaho mechanisms described below. See further description and a summary of the balances recorded under this mechanism below. 2016 General Rate Case On November 30, 2016 we filed a natural gas general rate case with the OPUC. We have requested an overall increase in base natural gas rates of 14.5 percent (designed to increase annual natural gas revenues by $8.5 million). Our request is based on a proposed ROR of 7.83 percent with a common equity ratio of 50 percent and a 9.9 percent ROE. The OPUC has up to l0 months to review our request and issue a decision. 12. On May 16, 2016 Marian Durkin was named Corporate Secretary, in addition to her current role as Senior Vice President, General Counsel and Chief Compliance Officer. The former Corporate Secretary, Karen Feltes, will retain her previous responsibilities as Senior Vice President and Chief Human Resources Officer and continue to serve as the lead executive for the Board of Directors Compensation and Organization Committee. On June 30,2016, Avista Corp.'s Board of Directors decided to increase the number of board members from l0 to I I and elected Scott H. Maw to fill the vacancy and serve as a director on the board effective August 1,2016. On July 31,2016, Roger Woodworth, Vice President of Avista Corp. retired. 13.

NOTES TO FINAI\CIAL STATEMENTS NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Business Avista Corp. (the Company) 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 eastern Washinglon and northem Idaho. Avista Corp. also provides natural gas distribution service in parts of northeastern 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. AERC is a wholly-owned subsidiary of Avista Corp. The primary subsidiary of AERC is AEL&P, which comprises Avista Corp.'s FERC FORM NO. 2/3-Q 1 122.1 Name of Respondent Avista Corporation This Report is: (1) X An Originale\ A Resubmission Date of Report (Mo, Da, Yr) o3t31t2017 Year/Period of Report 2016tQ4 Notes to Financial Statements regulated utility operations in Alaska. AERC was acquired by Avista Corp. on July l, 2014 and there are no AERC earnings included in the overall results of Avista Corp. prior to that date. See Note 3 for information regarding the acquisition of AERC. Avista Capital, a wholly owned non-regulated subsidiary of Avista Corp., is the parent company of all of the subsidiary companies except AERC (and its subsidiaries). 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. See Note 4 for information regarding the disposition of Ecova. Bosis 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. ln 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) deferred income taxes associated with accounts other than utility property, 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 of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates include: o determining the market value of energy commodity derivative assets and liabilities, o pension and other postretirement benefit plan obligations, . contingent liabilities, o goodwill impairment testing, . recoverability ofregulatory assets, and r 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 Accounts 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. Regulafion 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 particular aspects of its operations. FERC FORM NO.2/3-O (REV't2-07)122.2 Name of Respondent Avista Corporation This Report is: (1) XAn OriginalQ\ A Resubmission Date of Report (Mo, Da, Yr) 03t31t2017 Year/Period of Report 2016/04 Notes to Financial Statements Operating Revenues Operating revenues related to the sale ofenergy 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: o the number of customers, . current rates, . meter reading dates, . actual native load for electricity, . actual throughput for natural gas, and r 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 31 (dollars in thousands): 2016 2015 Unbilled accounts receivable $ 69,544 $ 59,405 Depreciation 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 3l: 2016 2015 Ratio ofdepreciation to average depreciable property The average service lives for the following broad categories of utility plant in service are (in years) Electric thermaVother production Hydroelectric production Electric transmission Electric distribution Natural gas distribution property Other shorter-lived general plant 3.1l%o 3.09% Avista Corp. 4t 78 57 35 45 9 Taxes Other Than Income Taxes Taxes other than income taxes include state excise taxes, city occupational and franchise taxes, real and personal property taxes and certain other taxes not based on 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.

As prescribed by regulatory authorities, AFUDC is capitalized as a part of the cost of utility plant. The debt component of AIUDC 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 3l: 2016 201s Effective AFUDC rate 7.29%7.32Yo Income Taxes Deferred income tax assets represent future income tax deductions the Company expects to utilize in future tax retums to reduce taxable income. Deferred income tax liabilities represent future taxable income the Company expects to recognize in future tax returns. Deferred tax assets and liabilities arise when there are temporary differences resulting from differing treatment of items for tax and accounting purposes (such as depreciation). A deferred income tax asset or liability is determined based on the enacted tax rates that will be in effect when the temporary 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 unless a regulatory order specifies deferral of the effect of the change in tax rates over a longer period oftime. The Company establishes a valuation allowance when it is more likely than not that all, or a portion, of a deferred tax asset will not be realized. Deferred income tax liabilities and regulatory assets are established for income tax benefits flowed through to customers. The Company did not incur any penalties on income tax positions in 2016 or 20 I 5. The Company would recognize interest accrued related to income tax positions as interest expense and any penalties incurred as income deductions. S toc k- B as e d C omp e ns atio n The Company currently 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 liability 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): FERC FORM NO. 2/3-Q (REV 12-07)122.4 Name of Respondent Avista Concoration This Report is: (1) X An OriginalQl A Resubmission Date of Report (Mo, Da, Yr) 03131t2017 Year/Period of Report 2016tQ4 Notes to Financial Statements 20t6 2015 Stock-based compensation expense Income tax benefits (l) 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 $7,891 $ 6,914 4,359 2,420 (1) Income tax benefits for 2016 include $1.6 million associated with excess tax benefits on settled share-based employee payments. The excess tax benefits were recognized in the Statement of Income for 2016 due to the adoption of ASU 2016-09, effective January l, 2016. See Note 2 for further discussion. 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 retum on equity target in order for the Chief Executive Officer'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 Return (TSR) awards are market-based awards and Cumulative Earnings Per Share (CEPS) awards are performance awards. CEPS awards were first 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 settlement is at the discretion of the Company and historically the Company has seuled 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 con d iti ons. 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, if the 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. common 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: 20t6 2015 58,610 (52,385) 109,806 I,8s3 $ 58,302 (60,37e)) 106,091 1,705$ I 16,435 116,435 FERC FORM NO.

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 eamed 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 December 31,2016 and 2015, the Company had recognized cumulative compensation expense and a liability of $1.5 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 I I ow ance fo r D o u btfu I Ac c o u nts 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 funds used during construction and replacements of units of property 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 et Reti re me nt O blig at io ns The Company records the fair value of a liability for an 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 ofthe 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 ofthe 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 FERC FORM NO.2/3.Q 1 122.6 Name of Respondent Avista Corporation This Report is: (1) X An OriginalQ\ A Resubmission Date of Report (Mo, Da, Yr) 0313112017 Year/Period of Report 2016/Q4 Notes to Financial Statements asset retirement costs are recovered through rates charged to customers (see Note 7 for further discussion of the Company's asset retirement obligations). Goodwill Goodwill arising from acquisitions represents the future economic benefit arising from other assets acquired in a business combination that are not individually identified and separately recognized. The Company evaluates goodwill for impairment using a qualitative analysis (Step 0) for AEL&P and a combination of discounted cash flow models and a market approach for the other subsidiaries on at least an annual basis or more frequently if impairment indicators arise. The Company completed its annual evaluation of goodwill for potential impairment as of November 30, 2016 and determined that goodwill was not impaired at that time. While, the Company does not have any goodwill amounts recorded on its FERC balance sheets, it does have goodwill at its subsidiaries and the amounts for goodwill are reflected in the investment in subsidiary companies. The following amounts were recorded as goodwill at the subsidiary companies and reflected through the investment in subsidiary companies on the FERC balance sheets (dollars in thousands): Total Balance as ofthe December 31,2015 Balance as of the December 31,2016 $ 52,426 S 12,979 $ (7,733) $ 57,672 s 52,426 $ 12,979 $ (7,733) $ 57,672 Accumulated impairment losses are attributable to the other businesses. Derivative Assets and Liabilities Derivatives are recorded as either assets or liabilities on the Balance Sheets measured at estimated fair value. 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. Realized benefits and costs result in adjustments to retail rates through PGAs, the ERM in Washington, the PCA mechanism in Idaho, and periodic general rates cases. The resulting regulatory assets have been concluded to be probable ofrecovery 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 of the contract that is determined to be other-than-temporary. For interest rate swap derivatives, Avista Corp. records all mark-to-market gains and losses in each accounting period as assets and Iiabilities, as well as offsetting regulatory assets and liabilities, such that there is no income statement impact. The interest rate swap derivatives are risk management tools similar to energy commodity derivatives. Upon settlement of interest rate swap derivatives, the regulatory asset or liability is amortized as a component of interest expense over the term of the associated debt. The Company records an offset of interest rate swap derivative assets and liabilities with regulatory assets and liabilities, based on the prior practice of the commissions to provide recovery through the ratemaking process. As of December 31, 20l6,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 natural gas derivatives). In addition, some master netting agreements allow tbr the netting of commodity derivatives and interest rate swap FERC FORM NO. 2/3-Q (REV 12-07)122.7 AEL&P Other Accumulated Impairment Losses Name of Respondent Avista Corporation This Report is: (1) X An Original(2\ A Resubmission Date of Report (Mo, Da, Yr) 0313'112017 Year/Period of Report 2016/Q4 Notes to Financial Statements derivatives for the same counterparty. 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. F air Valu e M eas ureme nts 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, defened compensation assets, as well as derivatives related to interest rate swap derivatives and foreign currency exchange derivatives, are reported at estimated fair value on the Balance Sheets. See Note l4 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, o 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 revenues are recognized. The Company also has decoupling revenue deferrals, which began in 2015. Decoupling revenue deferrals are recognized in the Statements oflncome during the period they occur (i.e. during the period ofrevenue shorrfall 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 future periods. GAAP requires that for any altemative regulatory revenue program, like decoupling, the revenue must be expected to be collected from customers within 24 months of the defenal to qualify for recognition in the current period Statement of Income. Any amounts included in the Company's decoupling program that are not expected to 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 decoupling revenue being recognized in a future period. 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 reguired to write off its regulatory assets, and . precluded from 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. Unamortized Debt kpense Unamortized debt expense includes debt issuance costs that are amortized over the life of the related debt. Ununoilized Gain/Loss on Reacquired Debt For the Company's Washington regulatory jurisdiction and for any debt repurchases beginning in 2007 in all jurisdictions, premiums or discounts 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 amounts are amortized over the life of the new debt. In the Company's other regulatory jurisdictions, premiums or discounts paid to repurchase debt prior to 2007 are being amortized over the average remaining FERC FORM NO.

The premiums and discounts are recovered or returned to customers through retail rates as a component ofinterest expense. App rop riate d Retain ed E arning s 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 eamings 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) ofthe FPA, the Company must maintain these excess eamings in an appropriated retained earnings account until the termination of the licensing agreements or apply them to reduce the net investment 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 ofreturn on an annual basis, usually during the second quarter. The appropriated retained earnings amounts included in retained earnings were as follows as of December 31 (dollars in thousands): 2016 2015 Appropriated retained eamings $ 23,869 S 19,428 Operating Leases The Company has multiple lease arrangements involving various assets, with minimum terms ranging from I to 45 years. 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 31,2016. Equity in Earnings (Losses) of Subsidiaries The Company records all the earnings (losses) from its subsidiaries under the equity method. The Company had the following equity in earnings (losses) of its subsidiaries for the years ended December 31 (dollars in thousands): 2016 201 5 Avista Capital Alaska Energy and Resources Company Total equity in earnings of subsidiary companies $ 6,289 $ ll,165 Subsequent Events Management has evaluated the impact of events occurring after December 31,2016 up to February 21,2077, the date that Avista Corp.'s U.S. GAAP financial statements were issued and has updated such evaluation for disclosure purposes through March 31, 2017. 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 6, 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 STAI\IDARDS $(1,434) $ 't,723 4,857 6,309 ASU No. 2014-09, "Revenuefrom Contracts with Customers (Topic 606)" FERC FORM NO. 2/3-Q (REV 12-07)122.9 Name of Respondent Avista Corporation This Report is: (1) X An OriginalQ\ A Resubmission Date of Report (Mo, Da, Yr) 03t31t2017 Year/Period of Report 2016tQ4 Notes to Financial Statements In May 2014,the FASB issued ASU No. 2014-09, 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 should identiff the various performance obligations in a contract, allocate the transaction price among the performance obligations and recognize revenue when (or as) the entity satisfies each performance obligation. This ASU was originally effective for periods beginning after December 15,2016 and early adoption was not permitted. In August 2015, the FASB issued ASU No. 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which deferred the effective date of ASU No. 2014-09 for one year, with adoption as of the original date permitted. The Company has formed a revenue recognition standard implementation team that is working through several implementation issues described below. The Company has evaluated this standard and is planning to adopt this standard in 2018 upon its effective date. The Company is currently expecting to use a modified retrospective method of adoption, which would require a cumulative adjustment to opening retained eamings, as opposed to a full retrospective application. The Company is not far enough along in the adoption process to determine the amount, if any, of cumulative adjustment necessary. Since the vast majority of Avista Corp.'s revenue is from rate-regulated sales of electricity and natural gas to retail customers and revenue is recognized as energy is delivered to these customers, the Company does not expect a significant change in operating revenues or net income. The Company is in the process of reviewing and analyzing certain contracts with customers (most of which are related to wholesale sales of power and natural gas), but has not yet identified any significant differences in revenue recognition between current GAAP and ASU 2014-09. During the implementation process, the Company has identified several unresolved issues, the most significant of which are as follows based on our current assessment: Contributions in Aid of Construction - There is the potential that CIACs could be recognized as revenue upon the adoption of ASU 2014-09. Under current GAAP, CIACs are accounted for as an offset to the cost of utility plant in service. Utililv Related Tues Collected.from Customers - There are questions on the presentation of utility related taxes collected from customers (primarily state excise taxes and city utility taxes) on a gross basis. Under current GAAP, the Company is allowed to record these utility related taxes on a gross basis in revenue when billed to customers with an offset included in taxes other than income taxes in operating expenses. The Company is evaluating whether this presentation is appropriate under ASU 2014-09 or whether they should be presented on a net basis. To qualify for gross presentation under the new guidance, the Company must perform an analysis to determine if it is the principal or the agent in regards to utility related taxes. Collectibilitv - There are questions regarding the requirement that collection of a sale be probable and how, or if, utilities should consider bad debt collection mechanisms (riders, base rate adjustments, etc.) in assessing probability of collection on sales to low income customers. Within the utility industry, there is support for and against considering these recovery mechanisms when assessing collectibility of a sale. If the bad debt recovery mechanisms cannot be considered, there is the potential that certain sales to low income customers cannot be recognized as revenue until payment is received from the customers, which could result in revenues being recognized in periods other than when the energy was delivered to customers or not recognized at all. The Company is monitoring utility industry implementation guidance as it relates to unresolved issues to determine if there will be an industry consensus regarding accounting and presentation ofthese items. ASU No. 2016-02 "Leases (Topic 842)." FERC FORM NO. 2/3-Q 1 122.10 In February 2076,ihe FASB issued ASU No. 2016-02. This ASU introduces a new lessee model that requires most leases to be Name of Respondent Avista Comoralion This Report is: (1) X An Originale\ A Resubmission Date of Report (Mo, Da, Yr) 03t31t2017 Year/Period of Report 2016/Q4 Notes to Financial Statements capitalized and shown on the balance sheet with corresponding lease assets and liabilities. The standard also aligns certain of the underlying principles of the new lessor model with those in Topic 606, the FASB's new revenue recognition standard. Furthermore, this ASU addresses other issues that arise under the current lease 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. Upon adoption, this ASU must be applied using a modified retrospective approach to the earliest period presented, which will likely require restatements of previously issued financial statements. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. The Company evaluated this standard and determined that it will most likely not early adopt this standard before its effective date in 2019. The Company has formed a lease standard implementation team that is working through the implementation process. The most significant implementation challenge identified thus far relates to identifoing a complete population of leases and potential leases under the new lease standard. Also, the Company is monitoring utility industry implementation guidance as it relates to several unresolved issues to determine if there will be an industry consensus, including whether right-of-ways are considered leases. The Company cannot, at this time, estimate the potential impact on its future financial condition, results of operations and cash flows. ASU No. 2016-09 "Compensation-StockCompensotion (Topic 718): Improvements to Employee Share-Based Payment Accounting." In March 2016,the FASB issued ASU No. 2016-09. This ASU simplifies several aspects of the accounting for employee share-based payment transactions including: e allowing excess tax benefits or tax deficiencies to be recognized as income tax benefits or expenses in the Statements of Income rather than in Additional Paid in Capital (APIC), . excess tax benefits no longer represent a financing cash inflow on the Statements of Cash Flows and instead will be included as an operating activity, . excess tax benefits and tax deficiencies will be excluded from the calculation ofdiluted earnings per share, whereas under current accounting guidance, these amounts must be estimated and included in the calculation, o allowing forfeitures to be accounted for as they occur, instead of estimating forfeitures, and o changing the statutory tax withholding requirements for share-based payments. This ASU is effective for periods beginning after December 15,2016 and early adoption is permitted. The Company early adopted this standard during the second quarter of 2076, with a retrospective effective date of January 1,2016. The adoption of this standard resulted in a recognized income tax benefit of $l.6 million in 2016 associated with excess tax benefits on settled share-based employee payments. In addition, the Statement of Cash Flows for 2016 included the excess tax benefits as an operating activity rather than as a financing activity. Periods prior to 2016 were not restated for the adoption of this accounting standard as the Company has adopted this standard on a prospective basis beginning January 1 ,2016. ASU No. 2017-07 "Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost" In March 2017,the FASB issued ASU No. 2017-07, which amends the income statement presentation of the components of net period benefit cost for an entity's defined benefit pension and other postretirement plans. Under current GAAP, net benefit cost consists of several components that reflect different aspects of an employer's financial arrangements as well as the cost of benefits eamed by employees. These components are aggregated and reported net in the financial statements. ASU 2017-07 requires entities to (1) disaggregate the current-service-cost component from the other components ofnet benefit cost (other components) and present it with other current compensation costs for related employees in the income statement and (2) present the other components elsewhere in the income statement and outside of income from operations. FERC FORM NO.

This is a change from current practice, under which entities capitalize the aggregate net benefit cost when applicable. Because Avista Corp. is a rate-regulated entity and all components of net benefit cost are required to be capitalized within utility plant when applicable, this will result in a Regulatory/GAAP difference because for GAAP, the other components of net benefit cost will be capitalized as regulatory assets (because they are still allowable costs) but for regulatory reporting, they will be included in utility plant. This ASU is effective for periods beginning after December 15,2077 and early adoption is permitted. Upon adoption entities must use a retrospective transition method to adopt the requirement for separate presentation in the income statement and a prospective transition method to adopt the requirement to limit the capitalization of benefit costs to the service cost component. The Company evaluated this standard and does not expect to early adopt this standard. Also, the Company is still evaluating the impact to its financial statements upon adoption of this standard. NOTE 3. BUSINESS ACQUISITIONS Alaska Energlt snd 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 Juneau, Alaska. 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 diversiff Avista Corp.'s energy assets and deliver long-term value to its customers, communities and investors. In connection with the closing, Avista Corp. issued 4,501,441 new shares of common stock to the shareholders of AERC based on a contractual 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. Avista Corp. also paid S4.8 million in cash. The total fair value of all consideration transferred was $ I 54.9 million and resulted in goodwill of $52.4 million, which 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 retum 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 were 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 athactiveness 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 unrelated party to Avista Corp. The sales price was $335.0 million in cash, less the payment of debt and other customary closing adjustments. At the closing of the transaction on June 30,2014, Ecova became a wholly-owned subsidiary of Cofely USA Inc. and the Company has not had and will FERC FORM NO.

The purchase price of $335.0 million, as adjusted, was divided among all the security holders of Ecova pro rata based on ownership. After consideration of all 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 2015. NOTE 5. DERIVATIVES AND RISK MANAGEMENT E ne rglt C ommo di4t D e riv ative s Avista Corp. is exposed to market risks relating to changes in electricity and natural gas commodity prices and certain other fuel prices. 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 hansacts 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, the Company 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 the Company's distribution system. However, daily variations in natural gas demand can be significantly different than monthly demand projections. On the basis of these projections, the Company 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 Company is required to plan for sufficient natural gas delivery capacity to serve its retail customers for a theoretical peak day event. The Company generally has more pipeline and storage capacity than what is needed during periods other than a peak day. The Company optimizes its natural gas resources by using market opportunities to generate economic value that helps mitigate fixed costs. Avista Corp. also optimizes its natural gas storage capacity by purchasing and storing natural gas when prices are traditionally lower, typically in the summer, and withdrawing during higher priced months, typically during the winter. However, if market conditions and prices indicate that the Company should buy or sell natural gas during other times in the year, the Company engages in optimization transactions to capture value in the marketplace. Natural gas optimization activities include, but are not limited to, wholesale market sales of surplus natural gas supplies, purchases and sales of natural gas to optimize use of pipeline and storage capacity, and participation in the transportation capacity release market.

The electric and natural gas derivative contracts above will be included in either power 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. Any transactions that result in gains will be used to reduce retail rates charged to customers in the future. Foreign Currency Erchange Derivatives A significant portion of Avista Corp.'s natural gas supply (including fuel for power generation) is obtained from Canadian sources. Most of those ffansactions are executed in U.S. dollars, which avoids foreign currency risk. A portion of Avista Corp.'s short-term natural gas transactions and long-term Canadian transportation contracts are committed based on Canadian currency 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 derivatives when such commodity transactions are initiated. The foreign currency exchange derivatives and the unhedged foreign currency risk have 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 are 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 swap derivatives and U.S. Treasury lock agreements. These interest rate swap derivatives and U.S. Treasury lock agreements are considered economic hedges against fluctuations in future cash flows associated with anticipated debt issuances. The following table summarizes the unsettled interest rate swap derivatives that the Company has outstanding as of the balance sheet date indicated below (dollars in thousands): Mandatory Cash Settlement Balance Sheet Date Number of Contracts Notional Amount Date December 31,2016 75,000 275,000 70,000 20,000 60,000 2017 201 8 2019 2020 2022 6 l4 6 2 5 December 31,2015 6 J l1 2 I I 15,000 4s,000 24s,000 30,000 20,000 2016 2017 2018 2019 2022 During the third quarter 2016, in connection with the execution of a purchase agreement for bonds that the Company issued in December 2016,the Company cash-settled seven interest rate swap derivatives (notional aggregate amount of $125.0 million) and paid atotal of $54.0 million. The interest rate swap derivatives were settled in connection with the pricing of $175.0 million of Avista Corp. first mortgage bonds that were issued in December 2016 (see Note l2). Upon settlement of interest rate swap derivatives, the cash payments made or received are recorded as a regulatory asset or liability and are subsequently amortized as a component of interest expense over the life ofthe associated debt. The settled interest rate swap derivatives are also included as a part ofthe Company's cost of debt calculation for ratemaking purposes. The fair value ofoutstanding interest rate swap derivatives 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 swap derivatives if the fixed rates are higher than prevailing market rates at the date of settlement. Conversely, the Company receives cash to settle its interest rate swap derivatives when prevailing market rates at the time of settlement exceed the fixed swap rates.

NOTE 7. ASSET RETIREMENT OBLIGATIONS The Company has recorded liabilities for future AROs to: . restore coal ash containment ponds at Colstrip, . 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 final rule regarding coal combustion residuals (CCR), also termed coal combustion byproducts or coal ash, in the Federal Register, and this rule became effective on October 15, 2015. Colstrip, of which Avista Corp. is a 15 percent owner of units 3 & 4, produces this byproduct. The rule established technical requirements for CCR landfills and surface impoundments under 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, developed a multi-year compliance plan to strategically address the CCR requirements and existing state obligations while maintaining operational stability. During 2015, the operator of Colstrip provided an initial cost estimate of the expected retirement costs associated with complying with the new CCR rule. 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. During 2016, due to additional information and updated estimates, the ARO increased to $13.6 million (including accretion of $0.7 million). The actual asset retirement costs related to the CCR rule requirements may vary substantially from the estimates used to record the increased ARO 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 strategies 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 PLAIIS AIID 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 hiredpriortoJanuary l,2014.Individualbenefitsunderthisplanarebasedupontheemployee'syearsofservice,dateofhireand average compensation as specified in the plan. Non-union employees hired on or after January 1,2014 participate in a defined conhibution 401(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 2016, $12.0 million in 2015 and $32.0 million in2014. The Company expects to contribute $22.0 million in cash to the pension plan in 2017. 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): 2017 201 8 2019 2020 2021 Total 2022-2026 Expected benefit payments $ 30,971 $ 32,014 $ 33,047 $ 34,545 $ 35,892 $ 196,322 The expected long-term rate of retum on plan assets is based on past performance and economic forecasts for the types of investments 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 l, 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 l, 2014, will have access to the retiree medical plan upon retirement; however, Avista Corp. will no longer provide a contribution 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 officers 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 expects that benefit payments under other postretirement benefit plans will total (dollars in thousands): 2017 2018 2019 2020 2021 Total2022-2026 Expected benefit payments $ 6,991 $ 7302 $ 7,580 $ 6,479 $ 6,675 $ 34,704 The Company expects to contribute $7.0 million to other postretirement benefit plans in 2017, representing expected benefit payments to be paid during the year excluding the Medicare Part D subsidy.

The Company has contracted 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 intemal 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 investment consultant recommends allocation percentages by asset classes. These recommendations are reviewed by the intemal benefits committee, which FERC FORM NO. 2/3-Q (REV 12-07)122.21 Name of Respondent Avista Corporation This Report is: (1) X An Originale\ A Resubmission Date of Report (Mo, Da, Yr) 03t31t2017 Year/Period of Report 2016/Q4 Notes to Financial Statements 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 invesfrnent allocation percentages are typically the midpoint of the established range. The target investment allocation percentages by asset classes are indicated in the table below: 2016 2015 Equity securities Debt securities Real estate Absolute retum 37% 45o/o 8o/o 10% 27o/o 580 60/o 9% The 2016 target investment allocation percentages were revised in the fourth quarter of 2016 and the pension plan assets were subsequently reinvested during the fourth quarter of 2016 and first quarter of 2017 to move toward the new target investment allocation percentages. The target asset allocation percentages were modified to better align the asset allocations with the funded status of the pension plan. Future contributions to the plan will also be increased to improve the funded status of the plan. The fair value of pension plan assets invested in debt and equity securities was based primarily on fair value (market prices). The fair value of investment 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. lnvestment 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 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: . 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 Decemb er 3l , 2016 and 201 5. Pension plan other postretirement plan assets whose fair values are measured using net asset value (NAV) are excluded from the fair value hierarchy and are included as reconciling items in the tables below.

Employees can make contributions to their respective accounts in the plans on a pre-tax basis up to the maximum amount permitted by law. The Company matches a portion of the salary deferred by each participant according to the schedule in the respective plan. Employer matching contributions were as follows for the years ended December 3l (dollars in thousands): 2016 2015 Employer 401 (k) matching contributions $ 8,555 $ 7,875 The Company has an Executive Deferral Plan. This plan allows executive officers and other key employees the oppornrnity to defer until the earlier of their retirement, termination, disability or death, up to 75 percent of their base salary and/or up to 100 percent of their incentive payments. Deferred compensation funds are held by the Company in a Rabbi Trust. There were deferred compensation assets and corresponding deferred compensation liabilities on the Balance Sheets of the following amounts as of December 3l (dollars in thousands): 2016 2015 Deferred compensation assets and liabilities $ 7,679 $ 8,093 NOTE 9. ACCOUNTING FOR INCOME TAXES Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes and tax credit carryforwards. The realization of deferred income tax assets is dependent upon the ability to generate taxable income in future periods. 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 31,2016, the Company had $17.1 million of state tax credit carryforwards of which it is expected $7.9 million may expire unused; the Company has reflected the net amount of $9.2 million as an asset at December 31 ,2016. State tax credits expire from 2019 to2028. The Company and its eligible subsidiaries file consolidated federal income tax retums. The Company also files state income tax returns 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 Intemal Revenue Service (IRS) has completed its examination of all tax years through 2011 and all issues were resolved related to these years. The statute of limitations for the IRS to review the2012 tax year has expired, leaving the 2013 through 2015 taxyears still open for review. 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 contractual 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 31,2016 (principal and interest) was $65.2 million. In addition, Avista Corp. has operating agreements, settlements and other contractual obligations related to its generating facilities and transmission and distribution services.

Loans under this agreement were unsecured and had a variable annual interest rate. The Company borrowed the entire $70.0 million available under this agreement, which was used to repay a portion of the $90.0 million in first mortgage bonds that matured in August 2016. This term loan was subsequently repaid in full in December using the proceeds from the first mortgage bonds issued in December 2016 (discussed below). In December 2010, $66.7 million and $ I 7.0 million of the City of Forsyth, Montana Pollution Control Revenue Refunding Bonds (Avista Corporation Colstrip Project) due in2032 and2034, respectively, which had been held by Avista Corp. since 2008 and 2009, respectively, were refunded by new bond issues (Series 2010A and Series 2010B). The new bonds were not offered to the public and were purchased by Avista Corp. due to market conditions. The Company expects that at a later date, subject to market conditions, these bonds may be remarketed to unaffiliated investors. So long as Avista Corp. is the holder of these bonds, the bonds will not be reflected as an asset or a liability on Avista Corp.'s Balance Sheets. In December 2016, Avista Corp. issued and sold $175.0 million of 3.54 percent first mortgage bonds due in 2051 pursuant to a bond purchase agreement with institutional investors in the private placement market. The total net proceeds from the sale of the bonds were used to repay the $70.0 million term loan discussed above and to repay a portion of the bonowings outstanding under the Company's $400.0 million committed line of credit. In connection with the execution of the bond purchase agreement, the Company cash-settled seven interest rate swap derivatives (notional aggregate amount of $125.0 million) and paid a total of $54.0 million.

Under the Mortgage and Deed of Trust (Mortgage) securing its first mortgage bonds (including secured medium-term notes), Avista Corp. may issue additional fnst mortgage bonds under its mortgage in an aggregate principal amount equal to the sum of: 66-2/3 percent of the cost or fair value (whichever is lower) of property additions which have not previously been made the basis of any application under the Mortgage, or an equal principal amount of retired first mortgage bonds which have not previously been made the basis of any application under the Mortgage, or deposit ofcash. However, Avista Corp. may not issue any additional first mortgage bonds (with certain exceptions in the case of bonds issued on the basis of retired bonds) unless it has "net earnings" (as defined in the Mortgage) for any period of 12 consecutive calendar months out of the preceding l8 calendar months that were at least twice the annual interest requirements on all mortgage securities at the time outstanding, including the first mortgage bonds to be issued, and on all indebtedness of prior rank. As of December 3l ,2016, property additions and retired bonds would have allowed, and the net earnings test would not have prohibited, the issuance of $ I .2 billion in aggregate principal amount of additional first mortgage bonds at Avista Corp.

The Company owns 100 percent of Avista Capital II and has solely and unconditionally guaranteed the payment of distributions on, and redemption price and liquidation amount for, the Preferred Trust Securities to the extent that Avista Capital II has funds available for such payments from the respective debt securities. Upon maturity or prior redemption of such debt securities, the Preferred Trust Securities will be mandatorily redeemed. NOTE 14. 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 measurements) and the lowest priority to fair values derived from unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are defined as follows: Level 1 - 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 , but 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 judgmen! 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 FERC FORM NO.1 122.29 Name of Respondent Avista Corporation This Report is: (1) X An OriginalQ\ A Resubmission Date of Report (Mo, Da, Yr) 03t31t2017 Year/Period of Report 2016tQ4 Notes to Financial Statements 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 liabilities. 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 3 I (dollars in thousands): 2016 2015 Carrying Value Estimated Fair Value Carrying Value Estimated Fair Value Bonds (Level 2) Bonds (Level 3) Advances from associated companies (Level 3) December 31,2016 Assets: Energy commodity derivatives Level 3 energy commodity derivatives Natural gas exchange agreements Power exchange agreement Foreign curency exchange derivatives Interest rate swap derivatives Deferred compensation assets: Fixed income securities Equity securities Total Liabilities: $9s l,000 $ 587,000 51,547 1,048,661 S s83,073 38,660 951,000 $ 502,000 51,547 1,055,797 505,768 36,083 These estimates of fair value of long-term debt and long-term debt to affiliated trusts 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 parry brokers consisted of par values of 75.00 to 122.59, where a par value of 100.00 represents the carrying value recorded on the Balance Sheets. Level2 long-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 using comparable debt with similar risk and terms if there is no trading activity near a period end. Level 3 long-term debt consists of private placement bonds and debt to affiliated trusts, 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.

The difference between the amount of derivative assets and liabilities disclosed in respective levels in the table above and the amount of derivative assets and liabilities disclosed on the Balance Sheets is due to netting arrangements with certain counterparties. See Note 5 for additional discussion of derivative netting. FERC FORM NO. 2/3-Q 1 122.3'.1 $ Name of Respondent Avista Corporation This Report is: (1) X An Originale\ A Resubmission Date of Report (Mo, Da, Yr) 03t31t2017 Year/Period of Report 2016lA4 Notes to Financial Statements To establish fair value for energy commodity derivatives, 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 (I.[YMEX) 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 Level2. To establish fair values for interest rate swap derivatives, 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 derivatives 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 swap derivatives 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 ofthe 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 $0.4 million as of December 31,2016 and $0.6 million as of December 31,2015. Level 3 Fuir Vslue Under the power exchange agreement the Company purchases power at a price that is based 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 intemally 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 transactions 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 inpu8 not observable or corroborated in the market. These inputs include: l) the strike price (which is an internally 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. 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 strike price and volatility assumptions used in the calculation. FERC FORM NO. Z3.Q (REV 12-07)122.32 For the natural gas commodity exchange agreement, the Company uses the same Level 2 brokered quotes described above; however, Name of Respondent Avista Corporation This Report is: (1) X An OriginalQl A Resubmission Date of Report (Mo, Da, Yr) 03t31t2017 Year/Period of Report 2016tQ4 Notes to Financial Statemonts the Company also estimates the purchase and shles 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. Historically, the timing and volume of transactions have not been highly correlated with market prices and market volatility. The following table presents the quantitative information which was used to estimate the fair values of the Level 3 assets and liabilities above as of December 31,2076 (dollars in thousands): Fair Value (NeQ at December 31, 2016 Valuation Technique Unobservable Input Range Power exchange agreement $(13,449) Surrogate facility pricing O&M charges $33.59-$49.154{Wh (l) Escalation factor Transaction volumes 3o/o - 2017 to 2019 241,558 - 396,984 MWhs Power option agreement (76)Black-Scholes- Merton Strike price $37.83/MWh - 2019 Delivery volumes Volatility rates $54.404,1Wh - 2018 157,517 -285,979 MWhs 0.20 (2) Natural gas exchange agreement (5,885) Internallyderived weighted-average cost ofgas Forward purchase prices Forward sales prices Purchase volumes Sales volumes $1.83 - $3.06/mmBTU $1.90 - $5.14lmmBTU I15,000 - 310,000 mmBTUs 60,000 - 310,000 mmBTUs (l ) The average O&M charges for the delivery year beginning in November 2016 were $39.22 per MWh. For ratemaking purposes the average O&M charges to be included for recovery in retail rates vary slightly between regulatory jurisdictions. The average O&M charges for the delivery year beginning in 201 6 were $44.33 for Washington and $39.22 for Idaho. (2) The estimated volatility rate of 0.20 is compared to actual quoted volatility rates of 0.35 for 2017 to 0.26 in December 2018. The valuation methods, significant inputs and resulting fair values described above were developed by the Company's management and are reviewed on at least a quarterly basis to ensure they provide a reasonable estimate of fair value each reporting period.

Ln2016, the Company also issued $1.7 million (net of issuance costs) of common stock under the employee plans. NOTE 16. COMMITMENTS AIID CONTINGENCIES 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 litigation 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 of incuned costs through the ratemaking process. California Refund Proceeding In February 2016, APX, a market maker in the California Refund Proceedings in whose markets Avista Energy participated in the summer of 2000, 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 Pacific Gas & Electric (PG&E), Southern California Edison, San Diego Gas & Electric, the Califomia Attorney General (AG), the California Department of Water Resources (CERS), and the California Public Utilities Commission (together, the "Califomia Parties"). The penalty arises as a result of the FERC's 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 Energy believes its settlement with the California Parties in20l4 insulates it from any such liability and that as a dismissed pary 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. Pacift c Northwest Refu nd 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 finding 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 3,2071, the FERC issued an Order on Remand and on April 5, 2013 expanded 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. On July ll,2012 and March 28,2073, Avista Energy and Avista Corp. filed settlements of all issues in this docket with regard to the FERC FORM NO. 2/3-Q (REV t2-07)122.35 Name of Respondent Avista Corporation This Report is: (1) X An Original(2\ A Resubmission Date of Report (Mo, Da, Yr) 03t31t2017 Year/Period of Report 2016tQ4 Notes to Financial Statements claims made by the City of Tacoma and the California AG (on behalf of the California Department of Water Resources). The FERC approved the settlements and they are final. The remaining direct claimant against Avista Corp. and Avista Energy in this proceeding was the City of Seattle, Washington (Seattle). An evidentiary, trial type hearing before an Administrative Law Judge (ALJ) to permit parties to present evidence of unlawful market activity was conducted in 2013. With regard to the Seattle claims, on March 28,2074, the Presiding ALJ issued an 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 identify 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 N{ay 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. In October 2016, Seattle settled all of the matters with the remaining parties and withdrew its appeal at the Ninth Circuit. All the remaining parties signed the settlement agreement and a petition to dismiss the case was filed with the Ninth Circuit on October 27 , 2016. There are no remaining claims outstanding under this proceeding. The settlement did not have a material adverse effect on the Company's financial condition, results of operations or cash flows. Sienu Clab and Montana Environmental Information Cenur Litigation ln 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 Montan4 LLC (formerly PPL Montan4 LLC, an indirect subsidiary of Talen Energy Corporation), Puget Sound Energy, Portland General Electric Company, NorthWestern Energy and PacifiCorp. The Complaint alleged certain violations of the Clean Air Act, including the New Source Review, Title V and opacity requirements with respect to post-January I , 2001 Colstrip projects. The Plaintiffs requested 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 attomey fees. The liability trial was scheduled to start on May 31,2016. The parties engaged in settlement discussions with the Plaintiffs to resolve the claims raised in the litigation. On July 12,2076, the parties filed a proposed Consent Decree with the court which contained the terms of the settlement of the matter with respect to all four units at Colstrip. The settlement does not include any monetary payments by any parfy, dismisses all claims against all four units, and provides for the shut-down of units I & 2 (which are owned solely by Talen Montana,LLC and Puget Sound Energy) no later than July,2022. The Consent Decree was entered on September 6, 2016. The parties have petitioned the Court for costs and attomeys' fees. The Court denied the defendant's claim for fees and reduced the plaintiffsclaimedfeesfromapproximately$3.0millionto$l.6million.OnFebruary 15,2017 theCourtissuedanOrderadopting this resolution in full and closing the case. The Company does not expect that this matter will have a material adverse effect on its financial condition, results of operations or cash flows.

Under the terms of the Clark Fork Settlement Agreement (CFSA) 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 and Noxon Rapids In 1999, the United States Fish and Wildlife Service (USFWS) listed 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 CFSA 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 trout enhancement efforts. Parties to the CFSA are working to resolve several issues. The Company believes its ongoing efforts through the CFSA 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. C o I lective B arg aini ng A g ree mcnts The Company's collective bargaining agreements with the IBEW represent approximately 45 percent of all of Avista Corp.'s employees. A new three-year agreement with the local union in Washington and Idaho representing the majority (approximately 90 percent) of the Avista Corp.'s bargaining unit employees was approved in March 2016 and expires in March 2019. A three-year agreement in Oregon, which covers approximately 50 employees was set to expire in March 2017. A new three-year agreement has been approved by the IBEW membership that will expire in March 2020.lt is still awaiting approval from the National IBEW. There is a risk that ifcollective bargaining agreements expire and new agreements are not reached in each ofourjurisdictions, 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. Other Contingencies In the normal course of business, the Company has various other legal claims and contingent matters 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 incuned. 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.

Statements 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, ofall 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 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 17. REGULATORY MATTERS Power Cost Defenals 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: r short-term wholesale market prices and sales and purchase volumes, o the level and availability ofhydroelectric generation, r the level and availability of thermal generation (including changes in fuel prices), and o 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. The Washington ERM calculation is subject to certain deadbands and sharing bands. For 2016,the Company recognized a pre-tax benefit of $5.1 million under the ERM in Washington compared to a benefit of $6.3 million for 2015. Total net deferred power costs under the ERM were a liability of $21.3 million as of December 31,2016 compared to a liability of $18.0 million as of December 31,2075, and these deferred power cost balances represent amounts due to customers. Avista Corp. has a PCA mechanism in Idaho that allows it to modify 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. The 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 liability of $2.2 million as of December 31,2016 compared to an asset of $0.2 million as of December 31,2015. Natural Gas Cost Deferrals and Recovery Mechanisms Avista Corp. files a PGA in all three states it serves to adjust natural gas rates for: l) estimated commodity and pipeline transportation FERC FORM NO. 2/3-Q (REV 12-07)'122.38 Name of Respondent Avista Corporation This Report is: (1) X An Originale\ A Resubmission Date of Report (Mo, Da, Yr) 0313112017 Year/Period of Report 2016/Q4 Notes to Financial Statements 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 $30.8 million as of December37,2016 compared to a liability of $17.9 million as of December 31,2015. Decoupling and Earnings Sharing Mechanisms Decoupling is a mechanism designed to sever the link between a utility's revenues and consumers'energy usage. In each of Avista Corp.'s jurisdictions, each month Avista Corp.'s electric and natural gas revenues are adjusted so as to be based on the number of customers in certain customer rate classes, rather than KWh and therm sales. The difference between revenues based on the number of customers and revenues based on actual usage is 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 beginning January 1,2015. Electric and natural gas decoupling surcharge rate adjustments to customers are Iimited 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 rebate rate adjustments. The electric and natural gas decoupling mechanisms each include an after-the-fact eamings test. At the end of each calendar year, separate electric and natural gas eamings calculations will be made for the prior calendar year. These earnings tests will reflect actual decoupled revenues, normalized power supply costs and other normalizing adjustments. See below for a summary of cumulative balances under the decoupling and earnings sharing mechanisms. Idqho Fixed Cost Adjustment (FCA) and Earnings Sharing Mechanisms In Idaho, 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, beginning January 1,2016. For the period 201 3 through 20 I 5 the Company had an after-the-fact earnings test, such that if Avista Corp., on a consolidated basis for electric and natural gas operations in Idaho, earned 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 eamings test was discontinued as part of the settlement of the Company's 2015 Idaho electric and natural gas general rates cases. See below for a summary of cumulative balances under the decoupling and eamings sharing mechanisms. Ore gon Dec oupling Mec hqnism In February 2016, the OPUC approved the implementation of a decoupling mechanism for natural gas, similar to the Washington and Idaho mechanisms described above. The decoupling mechanism became effective on March 1,2016 and there will be an oppornrnity for interested parties to review the mechanism and recommend changes, if any, by September 2019. An earnings review is conducted on an annual basis, which is filed by the Company with the OPUC on or before June 1 of each year for the prior calendar year. In the annual earnings review, if the Company e.uns more than 100 basis points above its allowed retum on equity, one-third of the earnings above the 100 basis points would be deferred and later returned to customers. The earnings review is separate from the decoupling mechanism and was in place prior to decoupling. See below for a summary of cumulative balances under the decoupling and eamings sharing mechanisms.

For each construc{ion 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 difierent rates are applied to different types of construction, (e) basis of differentiation in rates for different types of construction, and (f) whether the overhead is directly or indireclly 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) of the Uniform System of Accounts. 3. \Mrere a net-of-tax rate for bonowed funds is used, show the appropriate tax effec{ adjustment to the computations below in a manner that clearly indicates the amount of reduction in the gross rate for tax effec{s. 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:o Construction Overhead North Gas. Construction Overhead South Gas Poolcosts are allocated monthly to gas construction p@ects 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 2016, Avista used a rate of 7.29o/o which is the allowed Rate of Return contained in the Washington Utilities and Transportation Commission Final Order 05 dated January 6, 2016 for consolidated dockets UE-150204 and UG-150205.
