Forward-Looking Statements

From time to time, we make forward-looking statements such as statements regarding projected or future:

financial performance;

cash flows;

capital expenditures;

dividends;

capital structure;

other financial items;

strategic goals and objectives;

business environment; and

plans for operations.

These statements are based upon underlying assumptions (many of which are based, in turn, upon further assumptions). Such statements are made both in our reports filed under the Securities Exchange Act of 1934, as amended (including this Quarterly Report on Form 10-Q), and elsewhere. Forward-looking statements are all statements except those of historical fact including, without limitation, those that are identified by the use of words that include “will,” “may,” “could,” “should,” “intends,” “plans,” “seeks,” “anticipates,” “estimates,” “expects,” “forecasts,” “projects,” “predicts,” and similar expressions.

Forward-looking statements (including those made in this Quarterly Report on Form 10-Q) are subject to a variety of risks, uncertainties and other factors. Most of these factors are beyond our control and may have a significant effect on our operations, results of operations, financial condition or cash flows, which could cause actual results to differ materially from those anticipated in our statements. Such risks, uncertainties and other factors include, among others:

Financial Risk

weather conditions, which affect both energy demand and electric generating capability, including the impact of precipitation and temperature on hydroelectric resources, the impact of wind patterns on wind-generated power, weather-sensitive customer demand, and similar impacts on supply and demand in the wholesale energy markets;

our ability to obtain financing through the issuance of debt and/or equity securities, which can be affected by various factors including our credit ratings, interest rates, other capital market conditions and global economic conditions;

changes in interest rates that affect borrowing costs, our ability to effectively hedge interest rates for anticipated debt issuances, variable interest rate borrowing and the extent to which we recover interest costs through retail rates collected from customers;

changes in actuarial assumptions, interest rates and the actual return on plan assets for our pension and other postretirement benefit plans, which can affect future funding obligations, pension and other postretirement benefit expense and the related liabilities;

deterioration in the creditworthiness of our customers;

the outcome of legal proceedings and other contingencies;

economic conditions in our service areas, including the economy's effects on customer demand for utility services;

declining energy demand related to customer energy efficiency, conservation measures and/or increased distributed generation;

changes in the long-term ~~global~~ climate and ~~the long-term climate within our utilities' service areas, which can~~weather may materially affect, among other things, customer demand, ~~patterns,~~ the volume and timing of streamflows ~~to our~~required for hydroelectric ~~resources, as well as increased risk~~generation, costs of generation, transmission and distribution. Increased or new risks may arise from severe weather or natural disasters, including wildfires;

industry and geographic concentrations which may increase our exposure to credit risks due to counterparties, suppliers and customers being similarly affected by changing conditions;

~~Table of Contents~~

~~AVISTA CORPORATION~~

Utility Regulatory Risk

state and federal regulatory decisions or related judicial decisions that affect our ability to recover costs and earn a reasonable return including, but not limited to, disallowance or delay in the recovery of capital investments, operating

Table of Contents

AVISTA CORPORATION

costs, commodity costs, interest rate swap derivatives, the ordering of refunds to customers and discretion over allowed return on investment;

the loss of regulatory accounting treatment, which could require the write-off of regulatory assets and the loss of regulatory deferral and recovery mechanisms;

Energy Commodity Risk

volatility and illiquidity in wholesale energy markets, including exchanges, the availability of willing buyers and sellers, changes in wholesale energy prices that can affect operating income, cash requirements to purchase electricity and natural gas, value received for wholesale sales, collateral required of us by individual counterparties and/or exchanges in wholesale energy transactions and credit risk to us from such transactions, and the market value of derivative assets and liabilities;

default or nonperformance on the part of any parties from whom we purchase and/or sell capacity or energy;

potential environmental regulations or lawsuits affecting our ability to utilize or resulting in the obsolescence of our power supply resources;

explosions, fires, accidents, pipeline ruptures or other incidents that may limit energy supply to our facilities or our surrounding territory, which could result in a shortage of commodities in the market that could increase the cost of replacement commodities from other sources;

Operational Risk

severe weather or natural disasters, including, but not limited to, avalanches, wind storms, wildfires, earthquakes, snow and ice storms, that can disrupt energy generation, transmission and distribution, as well as the availability and costs of fuel, materials, equipment, supplies and support services;

explosions, fires, accidents, mechanical breakdowns or other incidents that may impair assets and may disrupt operations of any of our generation facilities, transmission, and electric and natural gas distribution systems or other operations and may require us to purchase replacement power;

explosions, fires, accidents or other incidents arising from or allegedly arising from our operations that may cause wildfires, injuries to the public or property damage;

blackouts or disruptions of interconnected transmission systems (the regional power grid);

terrorist attacks, cyberattacks or other malicious acts that may disrupt or cause damage to our utility assets or to the national or regional economy in general, including any effects of terrorism, cyberattacks or vandalism that damage or disrupt information technology systems;

work force issues, including changes in collective bargaining unit agreements, strikes, work stoppages, the loss of key executives, availability of workers in a variety of skill areas, and our ability to recruit and retain employees;

increasing costs of insurance, more restrictive coverage terms and our ability to obtain insurance;

delays or changes in construction costs, and/or our ability to obtain required permits and materials for present or prospective facilities;

increasing health care costs and cost of health insurance provided to our employees and retirees;

cyberattacks on the operating systems that are used in the operation of our electric generation, transmission and distribution facilities and our natural gas distribution facilities, and cyberattacks on such systems of other energy companies with which we are interconnected, which could damage or destroy facilities or systems or disrupt operations for extended periods of time and result in the incurrence of liabilities and costs;

cyberattacks on the administrative systems that are used in the administration of our business, including customer billing and customer service, accounting, communications, compliance and other administrative functions, and cyberattacks on such systems of our vendors and other companies with which we do business, which could result in the disruption of business operations, the release of private information and the incurrence of liabilities and costs;

changes in costs that impede our ability to effectively implement new information technology systems or to operate and maintain current production technology;

changes in technologies, possibly making some of the current technology we utilize obsolete or introducing new cyber security risks;

insufficient technology skills, which could lead to the inability to develop, modify or maintain our information systems;

Strategic Risk

growth or decline of our customer base and the extent to which new uses for our services may materialize or existing uses may decline, including, but not limited to, the effect of the trend toward distributed generation at customer sites;

the potential effects of negative publicity regarding our business practices, whether true or not, which could hurt our reputation and result in litigation or a decline in our common stock price;

changes in our strategic business plans, which may be affected by any or all of the foregoing, including the entry into new businesses and/or the exit from existing businesses and the extent of our business development efforts where potential future business is uncertain;

entering into or growth of non-regulated activities may increase earnings volatility;

potential legal proceedings arising from the termination of the proposed acquisition of the Company by Hydro One;

External Mandates Risk

changes in environmental laws, regulations, decisions and policies, including present and potential environmental remediation costs and our compliance with these matters;

the potential effects of initiatives, legislation or administrative rulemaking at the federal, state or local levels, including possible effects on our generating resources, prohibitions or restrictions on new or existing services, or restrictions on greenhouse gas emissions to mitigate concerns over global climate changes;

political pressures or regulatory practices that could constrain or place additional cost burdens on our distribution systems through accelerated adoption of distributed generation or electric-powered transportation or on our energy supply sources, such as campaigns to halt coal-fired power generation and opposition to other thermal generation, wind turbines or hydroelectric facilities;

wholesale and retail competition including alternative energy sources, growth in customer-owned power resource technologies that displace utility-supplied energy or that may be sold back to the utility, and alternative energy suppliers and delivery arrangements;

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

The accompanying condensed consolidated financial statements of Avista Corp. as of and for the interim periods ended ~~March 31,~~September 30, 2019 and ~~March 31,~~September 30, 2018 are unaudited; however, in the opinion of management, the statements reflect all adjustments necessary for a fair statement of the results for the interim periods. All such adjustments are of a normal recurring nature. The condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. The Condensed Consolidated Statements of Income for the interim periods are not necessarily indicative of the results to be expected for the full year. These condensed consolidated financial statements do not contain the detail or footnote disclosure concerning accounting policies and other matters which would be included in full fiscal year consolidated financial statements; therefore, they should be read in conjunction with the Company's audited consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2018 (2018 Form 10-K).

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Business

Avista Corp. is primarily an electric and natural gas utility with certain other business ventures. Avista Utilities is an operating division of Avista Corp., comprising its regulated utility operations in the Pacific Northwest. Avista Utilities provides electric distribution and transmission, and natural gas distribution services in parts of eastern Washington and northern Idaho. Avista Utilities also provides natural gas distribution service in parts of northeastern and southwestern Oregon. Avista Utilities has electric generating facilities in Washington, Idaho, Oregon and Montana. Avista Utilities also supplies electricity to a small number of customers in Montana, most of whom are employees who operate the Company'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 regulated utility operations in Alaska.

Avista Capital, a wholly owned non-regulated subsidiary of Avista Corp., is the parent company of all of the subsidiary companies in the non-utility businesses, with the exception of AJT Mining Properties, Inc., which is a subsidiary of AERC. See Note 1617 for business segment information. See Note 1819 for discussion of ~~assets held for~~the sale atof METALfx, an unregulated subsidiary of the Company.

Basis of Reporting

The condensed consolidated financial statements include the assets, liabilities, revenues and expenses of the Company and its subsidiaries and other majority owned subsidiaries and variable interest entities for which the Company or its subsidiaries are the primary beneficiaries. Intercompany balances were eliminated in consolidation. The accompanying condensed consolidated financial statements include the Company’s proportionate share of utility plant and related operations resulting from its interests in jointly owned plants.

Derivative Assets and Liabilities

Derivatives are recorded as either assets or liabilities on the Condensed Consolidated Balance Sheets measured at estimated fair value.

The WUTC 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 rate cases. The resulting regulatory assets associated with energy commodity derivative instruments have been concluded to be probable of recovery through future rates.

Substantially all forward contracts to purchase or sell power and natural gas are recorded as derivative assets or liabilities at estimated fair value with an offsetting regulatory asset or liability. Contracts that are not considered derivatives are accounted for on the accrual basis until they are settled or realized unless there is a decline in the fair value 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 liabilities, 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 cash payments made or received are recorded as a regulatory asset or liability isand are subsequently amortized as a component of interest expense over the ~~term~~life of the associated debt. The ~~Company records an offset of~~settled interest rate swap ~~derivative assets and liabilities with regulatory assets and liabilities, based on the prior practice~~derivatives are also included as a part of ~~the commissions to provide recovery through the~~Avista Corp.'s cost of debt calculation for ratemaking ~~process.~~purposes.

Table of Contents

AVISTA CORPORATION

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 for the netting of commodity derivatives and interest rate swap 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 Condensed Consolidated Balance Sheets.

Fair Value Measurements

Fair value represents the price that would be received when selling an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. Energy commodity derivative assets and liabilities, deferred compensation assets, as well as derivatives related to interest rate swaps and foreign currency exchange contracts, are reported at estimated fair value on the Condensed Consolidated Balance Sheets. See Note 1112 for the Company’s fair value disclosures.

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 loss contingencies that do not meet these conditions for accrual if there is a reasonable possibility that a material loss may be incurred. ~~As of~~ ~~March 31, 2019, the Company has not recorded any significant amounts related to unresolved contingencies.~~ See Note 1516 for further discussion of the Company's commitments and contingencies.

Reclassification to Comply with Required FERC Regulatory Reporting

During the third quarter of 2019, the FERC completed an audit of Avista Corp. that covered the period January 1, 2015 through December 31, 2018. Avista Corp.’s AFUDC rate, which is prescribed by state regulatory authorities, is different than the FERC approved method for calculating AFUDC. The FERC indicated that the difference in rates should be recorded as a regulatory asset rather than utility plant. At the conclusion of the audit, the FERC required Avista Corp. to reclass the excess AFUDC from Net utility plant to Non-current regulatory assets for the period January 1, 2010 (the effective date of the Company’s current fixed transmission rates) to the present. As a result of this finding, Avista Corp. reclassed approximately $37 million from Net utility plant to Non-current regulatory assets as of September 30, 2019, which represents the cumulative adjustment for 2010 through 2017. The Company recorded the difference in AFUDC rates for 2018 and 2019 as a regulatory asset in the respective periods incurred. The Company did not adjust prior period Condensed Consolidated Balances Sheets as the FERC required the adjustment to be reflected on a cumulative basis at the end of the audit and required the AFUDC calculation to be modified on a prospective basis. The Company concluded that the differences were insignificant during each prior period and on a cumulative basis. The adjustment recorded during the third quarter 2019 had no effect on net income or earnings per share.

NOTE 2. NEW ACCOUNTING STANDARDS

ASU No. 2016-02, "Leases (Topic 842)"

ASU No. 2018-01, "Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842"

ASU No. 2018-11, "Leases (Topic 842): Targeted Improvements"

On January 1, 2019, the Company adopted ASU No. 2016-02, which outlines a model for entities to use in accounting for leases and supersedes previous lease accounting guidance, as well as several practical expedients in ASU Nos. 2018-01 and 2018-11.

The Company adopted ASU No. 2016-02 utilizing a modified retrospective adoption method with the "package of three" and hindsight practical expedients offered by the standard. The "package of three" provides for an entity to not reassess at adoption whether any expired or existing contracts are deemed, for accounting purposes, to be or contain leases, the classification of any expired or existing leases, and any initial direct costs for any existing leases. As a result, the Company did not ~~apply~~reassess existing or expired contracts under the new lease guidance ~~to existing contracts that are or contain leases,~~ and it did not reassess the classification of ~~those~~any existing leases. The Company used the benefit of hindsight in determining both term and impairments associated with any existing leases. Use of this practical expedient has resulted in lease terms that best represent management's expectations with respect to use of the underlying asset but did not result in recognition of any impairment.

The Company elected to adopt ASU No. 2018-01, which allows an entity to exclude from application of Topic 842 all easements executed prior to January 1, 2019. In addition, the Company elected to adopt the "comparatives under 840" practical expedient offered in ASU No. 2018-11, which allows an entity to apply the new lease standard at the adoption date, recognizing any necessary cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption and presenting comparative periods in the financial statements under ASC 840 (previous lease accounting guidance). Adoption of the standard did not result in a cumulative effect adjustment within the Company's financial statements.

As allowed by ASU No. 2016-02, the Company elected not to apply the requirements of the standard to short-term leases, those leases with an initial term of 12 months or less. These leases are not recorded on the balance sheet and are immaterial to the financial statements.

Adoption of the standard impacted the Company's Condensed Consolidated Balance Sheet through recognition of right-of-use (ROU) assets and lease liabilities for the Company's operating leases. Accounting for finance leases (formerly capital leases) remained substantially ~~unchanged, except the Company reclassified the amounts as of December 31, 2018 to conform to the presentation of operating leases as of March 31, 2019.~~unchanged. See Note 5 for further information on the Company's leases.

ASU No. 2018-02 “Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”

In February 2018, the FASB issued ASU No. 2018-02, which amended the guidance for reporting comprehensive income. This ASU allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the enactment of the TCJA in December 2017. This ASU became effective for periods beginning after December

~~Table of Contents~~

~~AVISTA CORPORATION~~

15, 2018 and early adoption was permitted. Upon adoption, the requirements of this ASU must be applied either in the period of

AVISTA CORPORATION

adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the TCJA is recognized. The Company early adopted this standard effective January 1, 2018 and elected to apply the guidance during the period of adoption rather than apply the standard retrospectively. As a result, the Company reclassified $1.7 million in tax benefits from accumulated other comprehensive loss to retained earnings during the ~~three~~nine months ended ~~March 31,~~September 30, 2018.

ASU 2018-13 ~~" Fair~~"Fair Value Measurement (Topic 820)"

In August 2018, the FASB issued ASU No. 2018-13, which amends the fair value measurement disclosure requirements of ASC 820. The requirements of this ASU include additional disclosure regarding the range and weighted average used to develop significant unobservable inputs for Level 3 fair value estimates and the elimination of certain other previously required disclosures, such as the narrative description of the valuation process for Level 3 fair value measurements. This ASU is effective for periods beginning after December 15, 2019 and early adoption is permitted. Entities have the option to early adopt the eliminated or modified disclosure requirements and delay the adoption of all the new disclosure requirementsuntil the effective date of the ASU. The Company is in the process of evaluating this standard; however, it has determined that it will not early adopt any portion of this standard as of ~~March 31, 2019.~~September 30, 2019.

ASU No. 2018-14 "Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20)"

In August 2018, the FASB issued ASU No. 2018-14, which amends ASC 715 to add, remove and/or clarify certain disclosure requirements related to defined benefit pension and other postretirement plans. The additional disclosure requirements are primarily narrative discussion of significant changes in the benefit obligations and plan assets. The removed disclosures are primarily information about accumulated other comprehensive income expected to be recognized over the next year and the effects of changes associated with assumed health care costs. This ASU is effective for periods beginning after December 15, 2021 and early adoption is permitted. The Company is in the process of evaluating this standard; however, it has determined that it will not early adopt this standard as of ~~March 31, 2019.~~September 30, 2019.

NOTE 4. REVENUE

ASC 606 defines the core principle of the revenue recognition model is that an entity should identify 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.

~~AVISTA CORPORATION~~

Utility Revenues

Revenue from Contracts with Customers

General

The majority of Avista Corp.’s revenue is from rate-regulated sales of electricity and natural gas to retail customers, which has two performance obligations, (1) having service available for a specified period (typically a month at a time) and (2) the delivery of energy to customers. The total energy price generally has a fixed component (basic charge) related to having service available and a usage-based component, related to the delivery and consumption of energy. The commodity is sold and/or delivered to and consumed by the customer simultaneously, and the provisions of the relevant utility commission authorization determine the charges the Company may bill the customer. Given that all revenue recognition criteria are met upon the delivery of energy to customers, revenue is recognized immediately at that time.

Revenues from contracts with customers are presented in the Condensed Consolidated Statements of Income in the line item "Utility revenues, exclusive of alternative revenue programs."

Table of Contents

AVISTA CORPORATION

Non-Derivative Wholesale Contracts

The Company has certain wholesale contracts which are not accounted for as derivatives and, accordingly, are within the scope of ASC 606 and considered revenue from contracts with customers. Revenue is recognized as energy is delivered to the customer or the service is available for a specified period of time, consistent with the discussion of rate-regulated sales above.

Alternative Revenue Programs (Decoupling)

ASC 606 retained existing GAAP associated with alternative revenue programs, which specified that alternative revenue programs are contracts between an entity and a regulator of utilities, not a contract between an entity and a customer. GAAP requires that an entity present revenue arising from alternative revenue programs separately from revenues arising from contracts with customers on the face of the Condensed Consolidated Statements of Income. The Company's decoupling mechanisms (also known as a FCA in Idaho) qualify as alternative revenue programs. Decoupling revenue deferrals are recognized in the Condensed Consolidated Statements of Income during the period they occur (i.e. during the period of revenue shortfall or excess due to fluctuations in customer usage), subject to certain limitations, and a regulatory asset or liability is established that will be surcharged or rebated to customers in future periods. GAAP requires that for any alternative revenue program, like decoupling, the revenue must be expected to be collected from customers within 24 months of the deferral to qualify for recognition in the current period Condensed Consolidated 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. The amounts expected to be collected from customers within 24 months represents an estimate that must be made by the Company on an ongoing basis due to it being based on the volumes of electric and natural gas sold to customers on a go-forward basis.

Derivative Revenue

Most wholesale electric and natural gas transactions (including both physical and financial transactions), and the sale of fuel are considered derivatives, which are specifically scoped out of ASC 606. As such, these revenues are disclosed separately from revenue from contracts with customers. Revenue is recognized for these items upon the settlement/expiration of the derivative contract. Derivative revenue includes those transactions that are entered into and settled within the same month.

Other Utility Revenue

Other utility revenue includes rent, revenues from the lineman training school, sales of materials, late fees and other charges that do not represent contracts with customers.Other utility revenue also includes the provision for earnings sharing and the deferral and amortization of refunds to customers associated with the TCJA. This revenue is scoped out of ASC 606, as this revenue does not represent items where a customer is a party that has contracted with the Company to obtain goods or services that are an output of the Company’s ordinary activities in exchange for consideration. As such, these revenues are presented separately from revenue from contracts with customers.

Other Considerations for Utility Revenues

Gross Versus Net Presentation

Revenues and resource costs from Avista Utilities’ settled energy contracts that are “booked out” (not physically delivered) are reported on a net basis as part of derivative revenues.

Utility-related taxes collected from customers (primarily state excise taxes and city utility taxes) are taxes that are imposed on Avista Utilities as opposed to being imposed on its customers; therefore, Avista Utilities is the taxpayer and records these

~~AVISTA CORPORATION~~

transactions on a gross basis in revenue from contracts with customers and operating expense (taxes other than income taxes). The utility-related taxes collected from customers at AEL&P are imposed on the customers rather than AEL&P; therefore, the customers are the taxpayers and AEL&P is acting as their agent. As such, these transactions at AEL&P are presented on a net basis within revenue from contracts with customers.

Utility-related taxes that were included in revenue from contracts with customers were as follows for the three and nine months ended ~~March 31~~September 30 (dollars in thousands):

AVISTA CORPORATION

Non-Utility Revenues

Revenue from Contracts with Customers

Non-utility ~~revenues~~revenue from contracts with customers ~~are primarily~~is derived from contracts with one performance obligation. Prior to its sale in April 2019 (See Note 19 for further discussion on the ~~operations~~sale of ~~METALfx. The contracts associated with~~METALfx), METALfx ~~have~~had one performance obligation, the delivery of a product, and revenues ~~are~~were recognized when the risk of loss ~~transfers~~transferred to the customer, which ~~occurs~~occurred when products ~~are~~were shipped. The Steam Plant Brew Pub serves food and beverages to customers, its one performance obligation, and recognizes revenues at the time of service to the customer.

Significant Judgments and Unsatisfied Performance Obligations

The only significant judgments involving revenue recognition are estimates surrounding unbilled revenue and receivables from contracts with customers and estimates surrounding the amount of decoupling revenues that will be collected from customers within 24 months (discussed above).

The Company has certain capacity arrangements, where the Company has a contractual obligation to provide either electric or natural gas capacity to its customers for a fixed fee. Most of these arrangements are paid for in arrears by the customers and do not result in deferred revenue and only result in receivables from the customers. The Company does have one capacity agreement where the customer makes payments throughout the year and depending on the timing of the customer payments, it can result in an immaterial amount of deferred revenue or a receivable from the customer. As of ~~March 31,~~September 30, 2019, the Company estimates it had unsatisfied capacity performance obligations of ~~$9.1~~$7.0 million, which will be recognized as revenue in future periods as the capacity is provided to the customers. These performance obligations are not reflected in the financial statements, as the Company has not received payment for these services.

NOTE 5. LEASES

ASC 842, which outlines a model for entities to use in accounting for leases and supersedes previous lease accounting guidance, became effective on January 1, 2019. The core principle of the model is that an entity should recognize the ROU assets and liabilities that arise from leases on the balance sheet and depreciate or amortize the asset and liability over the term of the lease, as well as provide disclosure to enable users of the condensed consolidated financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases.

Significant Judgments and Assumptions

The Company determines if an arrangement is a lease, as well as its classification, at its inception.

ROU assets represent the Company's right to use an underlying asset for the lease term, and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating and finance lease ROU assets and lease liabilities are recognized at the commencement date of the agreement based on the present value of lease payments over the lease term. As most of the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date to determine the present value of lease payments. The implicit rate is used when it is readily determinable. The operating and finance lease ROU assets also include any lease payments made and exclude lease incentives, if any, that accrue to the benefit of the lessee.

Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Any difference between lease expense and cash paid for leased assets is recognized as a regulatory asset or regulatory liability.

Description of Leases

~~The Company has operating leases for land associated with its utility operations, as well as communication sites which support network and radio communications within its service territory.~~ Operating Leases

The Company's ~~leases have remaining terms of 1 to 74 years.~~

~~Table of Contents~~

~~AVISTA CORPORATION~~

~~Most of the Company's leases include options to extend the~~most significant operating lease ~~term for periods of 5 to 50 years. Exercise of these options~~ is ~~at the Company's discretion.~~

~~The Company has an operating lease~~ with the state of Montana associated with submerged land around the Company's hydroelectric facilities in the Clark Fork River basin, which expires in 2046. The terms of this lease are subject to renegotiation, depending on the outcome of ongoing litigation between Montana and NorthWestern Energy. In addition, the state of Montana and Avista Corp. are engaged in litigation regarding lease terms, including how much money, if any, the state of Montana will return to Avista Corp. Avista Corp. is currently paying all lease ~~terms.~~payments to the state of Montana into an escrow account until the litigation is resolved. As such, amounts recorded for this lease are uncertain and amounts may change in the future depending on the outcome of the ongoing litigation. Any reduction in future lease payments or the return of previously paid amounts to Avista Corp. will be including in the future ratemaking process.

In addition to the lease with the state of Montana, the Company also has other operating leases for land associated with its utility operations, as well as communication sites which support network and radio communications within its service territory. The Company's leases have remaining terms of 1 to 74 years. Most of the Company's leases include options to extend the lease term for periods of 5 to 50 years. Options are exercised at the Company's discretion.

Certain of the Company's lease agreements include rental payments which are periodically adjusted over the term of the agreement based on the consumer price index. The Company's lease agreements do not include any material residual value guarantees or material restrictive covenants.

AVISTA CORPORATION

Avista Corp. does not record leases with a term of 12 months or less in the Condensed Consolidated Balance Sheet. Total short-term lease costs for the three and nine months ended September 30, 2019 are immaterial.

Finance Lease

Through its wholly-owned subsidiary, AEL&P, the Company has a PPA which is treated as a finance lease for accounting purposes related to the Snettisham Hydroelectric Project, which expires in 2034. For ratemaking purposes, this lease is treated as an operating lease with a constant level of annual rental expense (straight line rent expense). Because of this regulatory treatment, any difference between the operating lease expense for ratemaking purposes and the expenses recognized under finance lease treatment (interest and amortization of the finance lease ROU asset) is recorded as a regulatory asset and amortized during the later years of the lease when the finance lease expense is less than the operating lease expense included in base rates. In 2018 and prior years, the total cost associated with the Snettisham PPA was included in resource costs. Due to the adoption of the new lease standard, the amortization of the ROU asset is now included in depreciation and amortization and the interest associated with the lease liability is now included in interest expense on the Condensed Consolidated Statement of Income.

~~Avista Corp. does not record leases with a term of 12-months or less in the Condensed Consolidated Balance Sheet. Total short-term lease cost for the three months ended March 31, 2019 is immaterial.~~

Leases that Have Not Yet Commenced

In June 2018, the Company finalized a lease agreement for office space in Spokane, Washington. The lease period is expected to commence in April 2020, once the Company takes possession of its portion of its portion of the building. The lease is an operating lease for a term of 12 years and will result in annual rent expense of approximately $1.1 million, which will be reflected in other operating expenses. In addition to base rent expense, the Company is expected to share in a portion of the annual operating expenses of the building.

In March 2019, the Company signed a PPA with Clearway Energy Group (Clearway) to purchase all of the power generated from the Rattlesnake Flat Wind project in Adams County, Washington. The facility has a nameplate capacity of 144 MW and is expected to generate approximately 50 aMW. During negotiations with Clearway, Avista Corp. was involved in the selection of the preferred generation facility type. The PPA is a 20-year agreement with deliveries expected to begin in 2020. The PPA provides Avista Corp. with additional renewable energy, capacity and environmental attributes. Avista Corp. expects to recover the cost of the power purchased through its retail rates. This PPA is considered a lease under ASC 842; however, all of the payments are variable payments based on whether power is generated from the facility. Since all the payments are variable, the Company will not record a lease liability for the agreement, but the expense will be included in resource costs when it becomes operational in 2020.

The components of lease expense were as follows for the three and nine months ended ~~March 31~~September 30, 2019 (dollars in thousands):

NOTE 6. DERIVATIVES AND RISK MANAGEMENT

Energy Commodity Derivatives

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, swap derivatives and options, in order to manage the various risks relating to these commodity price exposures. Avista Corp. has an energy resources risk policy and control procedures to manage these risks.

As part of Avista Corp.'s resource procurement and management operations in the electric business, Avista Corp. engages in an ongoing process of resource optimization, which involves the economic selection from available energy resources to serve Avista Corp.'s load obligations and the use of these resources to capture available economic value through wholesale market transactions. These include sales and purchases of 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 a portion of the related financial risks. These transactions range from terms of intra-hour up to multiple years.

As part of its resource procurement and management of its natural gas business, Avista Corp. makes continuing projections of its natural gas loads and assesses available natural gas resources including natural gas storage availability. Natural gas resource planning typically includes peak requirements, low and average monthly requirements and delivery constraints from natural gas supply locations to Avista Corp.’s distribution system. However, daily variations in natural gas demand can be significantly different than monthly demand projections. On the basis of these projections, Avista Corp. plans and executes a series of transactions to hedge a portion of its projected natural gas requirements through forward market transactions and derivative instruments. These transactions may extend as much as four natural gas operating years (November through October) into the future. Avista Corp. also leaves a significant portion of its natural gas supply requirements unhedged for purchase in short-term and spot markets.

Avista Corp. plans for sufficient natural gas delivery capacity to serve its retail customers for a theoretical peak day event. Avista Corp. generally has more pipeline and storage capacity than what is needed during periods other than a peak-day. Avista Corp. 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 Avista Corp. should buy or sell natural gas at other times during the year, Avista Corp. 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.

(ERM, PCA and PGAs), or in the general rate case process, and are expected to be collected through retail rates from customers.

Foreign Currency Exchange Derivatives

A significant portion of Avista Corp.’s natural gas supply (including fuel for power generation) is obtained from Canadian sources. Most of those transactions 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 Avista Corp.’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 following table summarizes the foreign currency exchange derivatives that Avista Corp. has outstanding as of ~~March 31,~~September 30, 2019 and December 31, 2018 (dollars in thousands):

Interest Rate Swap Derivatives

Avista Corp. is affected by fluctuating interest rates related to a portion of its existing debt, and future borrowing requirements. Avista Corp. 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 fair value of outstanding interest rate swap derivatives can vary significantly from period to period depending on the total notional amount of swap derivatives outstanding and fluctuations in market interest rates compared to the interest rates fixed by the swaps. Avista Corp. is required to make cash payments to settle the interest rate swap derivatives when the fixed rates are higher than prevailing market rates at the date of settlement. Conversely, Avista Corp. receives cash to settle its interest rate swap derivatives when prevailing market rates at the time of settlement exceed the fixed swap rates.

Exposure to Demands for Collateral

Avista Corp.'s derivative contracts often require collateral (in the form of cash or letters of credit) or other credit enhancements, or reductions or terminations of a portion of the contract through cash settlement. In the event of a downgrade in Avista Corp.'s credit ratings or changes in market prices, additional collateral may be required. In periods of price volatility, the level of exposure can change significantly. As a result, sudden and significant demands may be made against Avista Corp.'s credit facilities and cash. Avista Corp. actively monitors the exposure to possible collateral calls and takes steps to mitigate capital requirements.

Certain of Avista Corp.’s derivative instruments contain provisions that require Avista Corp. to maintain an "investment grade" credit rating from the major credit rating agencies. If Avista Corp.’s credit ratings were to fall below "investment grade," it would be in violation of these provisions, and the counterparties to the derivative instruments could request immediate payment or demand immediate and ongoing collateralization on derivative instruments in net liability positions.

NOTE 9. COMMITTED LINES OF CREDIT

Avista Corp.

Avista Corp. has a committed line of credit with various financial institutions in the total amount of $400.0 million that expires in April 2021. The committed line of credit is secured by non-transferable first mortgage bonds of the Company issued to the agent bank that would only become due and payable in the event, and then only to the extent, that the Company defaults on its obligations under the committed line of credit.

Balances outstanding and interest rates of borrowings (excluding letters of credit) under the Company’s revolving committed line of credit were as follows as of ~~March 31,~~September 30, 2019 and December 31, 2018 (dollars in thousands):



	September 30,			December 31,
	2019			2018
Balance outstanding at end of period (1)	$	207,000		$	190,000
Letters of credit outstanding at end of period	$	13,503		$	10,503
Average interest rate at end of period	2.94		%	3.18		%

Average interest rate at end of period 3.31 % 3.18 %

(1)

As of ~~March 31,~~September 30, 2019 ~~and December 31, 2018,~~ there was $207.0 million outstanding under the ~~balance outstanding~~committed line of credit; however, $119.3 million was classified as short-term borrowings and the remaining $87.7 million was classified as long-term debt on the Condensed Consolidated Balance ~~Sheet.~~Sheet due to the Company's intention to refinance such amount on a long-term basis. The amount classified as long-term debt will be refinanced through the issuance and sale of first mortgage bonds in November 2019 pursuant to a bond purchase agreement entered into in September 2019. See Note 10 for further discussion of the bond purchase agreement and the refinancing of short-term debt on a long-term basis. The entire outstanding amount of the committed line of credit as of December 31, 2018 was classified as short-term borrowings.

AEL&P

AEL&P has a committed line of credit in the amount of ~~$25.0~~$25.0 million that expires in November ~~2019~~.2019. As of ~~March 31,~~September 30, 2019 and December 31, 2018, there were no borrowings or letters of credit outstanding under this committed line of credit. The committed line of credit is secured by non-transferable first mortgage bonds of AEL&P issued to the agent bank that would only become due and payable in the event, and then only to the extent, that AEL&P defaults on its obligations under the committed line of credit.

NOTE 10. LONG-TERM DEBT

In September 2019, the Company entered into a bond purchase agreement for $180.0 million of 3.43 percent first mortgage bonds due in 2049 through a private offering. The bonds are scheduled to be issued in November 2019 pursuant to the bond purchase agreement. The total net proceeds from the sale of the bonds will be used to repay maturing long-term debt of $90.0 million, repay a portion of the outstanding balance under Avista Corp.'s $400.0 million committed line of credit and for other general corporate purposes. In connection with entering into the bond purchase agreement, the Company cash-settled 6 interest rate swap derivatives (notional aggregate amount of $70.0 million) and paid a net amount of $13.3 million. See Note 6 for a discussion of interest rate swap derivatives.

Because the Company is refinancing short-term debt on a long-term basis, the Company has classified the $90.0 million maturing debt and $87.7 million of the committed line of credit that is expected to be paid off with the net proceeds of the first mortgage bonds as long-term debt.

NOTE ~~10.~~11. LONG-TERM DEBT TO AFFILIATED TRUSTS

In 1997, the Company issued Floating Rate Junior Subordinated Deferrable Interest Debentures, Series B, with a principal amount of $51.5 million to Avista Capital II, an affiliated business trust formed by the Company. Avista Capital II issued $50.0 million of Preferred Trust Securities with a floating distribution rate of LIBOR plus 0.875 percent, calculated and reset quarterly.

AVISTA CORPORATION

The distribution rates paid were as follows during the ~~three~~nine months ended ~~March 31,~~September 30, 2019 and the year ended December 31, 2018:



	September 30,		December 31,
	2019		2018
Low distribution rate	3.01	%	2.36	%
High distribution rate	3.40	%	3.61	%

Low distribution rate 3.50 % 2.36 %
High distribution rate 3.61 % 3.61 %
Distribution rate at the end of the period 3.50 % 3.61 %

Concurrent with the issuance of the Preferred Trust Securities, Avista Capital II issued $1.5 million of Common Trust Securities to the Company. The Preferred Trust Securities may be redeemed at the option of Avista Capital II at any time and mature on June 1, 2037. In December 2000, the Company purchased $10.0 million of these Preferred Trust Securities.

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. The Company does not include these capital trusts in its consolidated financial statements as Avista Corp. is not the primary beneficiary. As such, the sole assets of the capital trusts are $51.5 million of junior subordinated deferrable interest debentures of Avista Corp., which are reflected on the Condensed Consolidated Balance Sheets. Interest expense to affiliated trusts in the Condensed Consolidated Statements of Income represents interest expense on these debentures.

NOTE ~~11.~~12. FAIR VALUE

The carrying values of cash and cash equivalents, accounts and notes receivable, accounts payable, and short-term borrowings are reasonable estimates of their fair values. Long-term debt (including current portion and material capital leases) and long-term debt to affiliated trusts are reported at carrying value on the Condensed Consolidated 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 1 measurement) and the lowest priority to fair values derived from unobservable inputs (Level 3 measurement).

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 judgment, and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels. The determination of the fair values incorporates various factors that not only include the credit standing of the counterparties involved and the impact of credit enhancements (such as cash deposits and letters of credit), but also the impact of Avista Corp.’s nonperformance risk on its liabilities.

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 party brokers for debt with similar risk and terms. The price ranges obtained from the third party brokers consisted of par values of ~~74.00~~78.00 to ~~121.59,~~135.60, where a par value of 100.0 represents the carrying value recorded on the Condensed Consolidated Balance Sheets. Level 2 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 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. Due to the unique nature of the Snettisham capital lease obligation, the estimated fair value of these items was determined based on a discounted cash flow model using available market information. The Snettisham capital lease obligation was discounted to present value using the Morgan Markets A Ex-Fin discount rate as published on ~~March 31,~~September 30, 2019.

The following table discloses by level within the fair value hierarchy the Company’s assets and liabilities measured and reported on the Condensed Consolidated Balance Sheets as of ~~March 31,~~September 30, 2019 and December 31, 2018 at fair value on a recurring basis (dollars in thousands):

(1)	The Company is permitted to net derivative assets and derivative liabilities with the same counterparty when a legally enforceable master netting agreement exists. In addition, the Company nets derivative assets and derivative liabilities against any payables and receivables for cash collateral held or placed with these same counterparties.


(2)	These assets are included in other property and investments-net and other non-current assets on the Condensed Consolidated Balance Sheets.

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 Condensed Consolidated Balance Sheets is due to netting arrangements with certain counterparties. See Note 6 for additional discussion of derivative netting.

To establish fair value for energy commodity derivatives, the Company uses quoted market prices and forward price curves to estimate the fair value of energy commodity derivative 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 pricing for similar instruments, adjusted for basin differences, using market quotes. Where observable inputs are available for substantially the full term of the contract, the derivative asset or liability is included in Level 2.

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 curves are provided by third party brokers. The Company's credit spread is factored into the locked-in price of the foreign exchange contracts.

Level 3 Fair Value

Under the power exchange agreement, which expired on June 30, 2019, the Company ~~purchases~~purchased power at a price that iswas 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~~estimated the difference between the purchase price based on the future O&M charges and forward prices for energy. The Company ~~compares~~compared the Level 2 brokered quotes and forward price curves described above to an internally developed forward price which iswas based on the average O&M charges from the three surrogate nuclear power plants for the current year. The Company ~~estimates~~estimated the volumes of the transactions that ~~will~~would 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.

For the natural gas commodity exchange agreement, the Company uses the same Level 2 brokered quotes described above; however, the Company also estimates the purchase and sales volumes (within contractual limits) as well as the timing of those transactions. Changing the timing of volume estimates changes the timing of purchases and sales, impacting which brokered quote is used. Because the brokered quotes can vary significantly from period to period, the unobservable estimates of the timing and volume of transactions can have a significant impact on the calculated fair value. The Company currently estimates volumes and timing of transactions based on a most likely scenario using historical data. 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 ~~March 31,~~September 30, 2019 (dollars in thousands):

NOTE ~~15.~~16. COMMITMENTS AND 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 Utilities’ or AEL&P's operations, the Company intends to seek, to the extent appropriate, recovery of incurred costs through the ratemaking process.

Cabinet Gorge Total Dissolved Gas Abatement Plan

Dissolved atmospheric gas levels (referred to as "Total Dissolved Gas" or "TDG") in the Clark Fork River exceed state of Idaho and federal water quality numeric standards downstream of Cabinet Gorge particularly during periods when excess river flows must be diverted over the spillway. 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 Corp. is reducing TDG by

constructing spill crest modifications on spill gates at the dam. These modifications have been shown to be effective in reducing TDG downstream. TDG monitoring and analysis is ongoing. Under the terms of the mitigation plan, Avista Corp. will continue to work with stakeholders to determine the degree to which TDG abatement reduces future mitigation obligations. The Company has sought, and will continue to seek recovery, through the ratemaking process, of all operating and capitalized costs related to this issue.

Legal Proceedings Related to the Terminated Acquisition by Hydro One

See Note 1718 for information regarding the termination of the proposed acquisition of the Company by Hydro One.

In connection with the now terminated acquisition, three lawsuits were filed in the United States District Court for the Eastern District of Washington and were subsequently voluntarily dismissed by the plaintiffs.

One lawsuit was filed in the Superior Court for the State of Washington in and for Spokane County, captioned as follows:

~~Fink v. Morris, et al.,~~ ~~No. 17203616-6 (filed September 15, 2017, amended complaint filed October 25, 2017).~~


•	Fink v. Morris, et al., No. 17203616-6 (filed September 15, 2017, amended complaint filed October 25, 2017).

The complaint generally alleged that the members of the Board of Directors of Avista Corp. breached their fiduciary duties by, among other things, conducting an allegedly inadequate sale process and agreeing to the acquisition at a price that allegedly undervalued Avista Corporation, and that Hydro One Limited, Olympus Holding Corp., and Olympus Corp. aided and abetted those purported breaches of duty. The complaint sought various remedies, including monetary damages, attorneys’ fees and expenses. Subsequent to the termination of the proposed acquisition in January 2019, the complaint was voluntarily dismissed by the plaintiffs.

2015 Washington General Rate Cases

In January 2016, the Company received an order (Order 05) that concluded its electric and natural gas general rate cases that were originally filed with the WUTC in February 2015. New electric and natural gas rates were effective on January 11, 2016.

WUTC Order Denying Industrial Customers of Northwest Utilities / Public Counsel Joint Motion for Clarification, WUTC Staff Motion to Reconsider and WUTC Staff Motion to Reopen Record

In January 2016, the Industrial Customers of Northwest Utilities, the Public Counsel Unit of the Washington State Office of the Attorney General (PC) and the WUTC Staff, which is a separate party in the general rate case proceedings from the WUTC Advisory Staff, filed Motions for Clarification requesting the WUTC to clarify their attrition adjustment and the end result electric revenue amounts. The Motions for Clarification suggested that the electric revenue decrease should have been significantly larger than what was included in Order 05.

In February 2016, the WUTC issued an order (Order 06) denying the Motions summarized above and affirming Order 05, including an $8.1 million decrease in electric base revenue.

PC Petition for Judicial Review

In March 2016, PC filed in Thurston County Superior Court a Petition for Judicial Review of the WUTC's Order 05 and Order 06 described above. In April 2016, this matter was certified for review directly by the Court of Appeals, an intermediate appellate court in the State of Washington.

On August 7, 2018, the Court of Appeals issued a "Published Opinion" (Opinion) which concluded that the WUTC's use of an attrition allowance to calculate Avista Corp.'s rate base violated Washington law. In the Opinion, the Court stated that because the projected additions to rate base in the future were not "used and useful" for service at the time the request for the rate increase was made, they may not lawfully be included in the Company's rate base to justify a rate increase. Accordingly, the Court concluded that the WUTC erred in including an attrition allowance in the calculation of Avista Corp.’s electric and natural gas rate base. The Court noted, however, that the law does not prohibit an attrition allowance in the calculation, for ratemaking purposes, of recoverable operating and maintenance expense. Since the WUTC order provided one lump sum attrition allowance without distinguishing what portion was for rate base and which was for operating and maintenance expenses or other considerations, the Court struck all portions of the attrition allowance attributable to Avista Corp.'s rate base and reversed and remanded the case for the WUTC to recalculate Avista Corp.’s rates without including an attrition allowance in the calculation of rate base. On October 1, 2018, the Court of Appeals terminated its review of this case, remanding it back to the Thurston County Superior Court. On April 17, 2019, the Thurston County Superior Court issued a Remand Order, granting a Joint Motion of Avista Corp., PC and the WUTC to remand the case back to the WUTC. ~~A pre-hearing conference which will set forth the procedural schedule will be held on May 17, 2019.~~

~~The total attrition allowance approved by~~

AVISTA CORPORATION

On June 20, 2019, Avista Corp. filed testimony with the WUTC in ~~Order 05 and reaffirmed in Order 06 was $35.2 million, with $28.3 million related to electric and $6.9 million related to natural gas. The Company believes~~the remand case. In Avista Corp.'s testimony, it asserted that the potential amount to return to customers is limited to revenues collected during the 11 month period between the effective date of the 2015 general rate case and the resolution of the subsequent 2016 general rate case, which resolved in December 2016. In the remand testimony the Company also asserted that no refund is due to customers for the 2015 general rate cases because actual 2016 electric rate base was greater than the 2016 electric rate base allowed in ~~subsequent Washington~~the general rate ~~cases (specifically those approved~~case, which included the prohibited attrition allowance. In addition, while 2016 actual natural gas rate base was slightly lower than the rate base allowed in the general rate case including the attrition allowance, the Company had already provided a refund to customers as a part of its earnings sharing mechanism.

Subsequent to the Company's filing, other parties in the case filed testimony and asserted that Avista Corp. should refund to customers amounts ranging from approximately $3 million to approximately $77 million. These parties justified the proposed refund by claiming that the rates in question were in effect from 2016 to April ~~2018),~~2018 as opposed to the 11 months argued by Avista Corp. Further, the parties asserted that the WUTC ~~did not include any attrition allowance on rate base. Even though~~should, directly or indirectly, correct what they believe is a power supply calculation error (approximately $20 million), an issue that the WUTC already addressed and which the Company believes the ~~issue only relates~~Courts did not remand back to the ~~2015 general rate cases,~~WUTC for further process. While not its primary recommendation for a refund, the WUTC Staff included an alternative refund methodology in its testimony, which Avista Corp. calculates as calling for a refund of approximately $3 million, if limited to the 11 month period. While the Company does not agree as a legal matter with the positions of the other parties to the case, as a practical matter the Company believes that it is probable that it will refund some amount to customers. As such, as of September 30, 2019 the Company recorded a refund liability of approximately $3 million. Since the Company cannot predict the ultimate outcome of this matter at this time, the amount so recorded represents the Company's best current estimate of a potential loss.

Boyds Fire (State of Washington Department of Natural Resources v. Avista)

On August 19, 2019, the Company was served with a complaint filed by the State of Washington Department of Natural Resources, seeking recovery of fire suppression costs and related expenses incurred in connection with a wildfire that occurred in Ferry County, Washington in August 2018. Specifically, the complaint alleges that the fire, which became known as the “Boyds Fire,” was caused by a dead ponderosa pine tree falling into an overhead distribution line, and that, Avista was negligent in failing to identify and remove it before the tree came into contact with the line. Avista Corp. disputes that the tree in question was the cause of the fire, and that it was negligent in failing to identify and remove it. The case is in the early stages of discovery and the plaintiff has not yet provided a statement specifying damages. Because the resolution of this claim remains uncertain, legal counsel cannot ~~estimate how much,~~express an opinion on the extent, if any, of the ~~attrition allowance may be removed from~~Company’s liability, nor is it possible for the ~~general rate cases or if other amounts from subsequent general rate cases will be included.~~Company to estimate the impact of any outcome at this time. The Company intends to vigorously defend itself in the litigation.

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 incurred. Such a change, should it occur, could be significant. See "Note 20 of the Notes to Consolidated Financial Statements" in the 2018 Form 10-K for additional discussion regarding other contingencies.

NOTE ~~16.~~17. INFORMATION BY BUSINESS SEGMENTS

The business segment presentation reflects the basis used by the Company's management to analyze performance and determine the allocation of resources. The Company's management evaluates performance based on income (loss) from operations before income taxes as well as net income (loss) attributable to Avista Corp. shareholders. The accounting policies of the segments are the same as those described in the summary of significant accounting policies. Avista Utilities' business is managed based on the total regulated utility operation; therefore, it is considered one segment. AEL&P is a separate reportable business segment,

~~Table of Contents~~

~~AVISTA CORPORATION~~

as it has separate financial reports that are reviewed in detail by the Chief Operating Decision Maker and its operations and risks are sufficiently different from Avista Utilities and the other businesses at AERC that it cannot be aggregated with any other operating segments. The Other category, which is not a reportable segment, includes other investments and operations of various subsidiaries, as well as certain other operations of Avista Capital.

NOTE ~~17.~~18. TERMINATION OF PROPOSED ACQUISITION BY HYDRO ONE

On July 19, 2017, Avista Corp. entered into a Merger Agreement that provided for Avista Corp. to become an indirect, wholly-owned subsidiary of Hydro One, subject to the satisfaction or waiver of specified closing conditions, including approval by regulatory agencies. Hydro One, based in Toronto, is Ontario’s largest electricity transmission and distribution provider.

~~At the effective time~~Termination of the acquisition, each share of Avista Corp. common stock issued and outstanding, other than shares of Avista Corp. common stock that are owned by Hydro One and its affiliates, were to be converted automatically into the right to receive an amount in cash equal to $53, without interest.Merger Agreement

~~Table of Contents~~

~~AVISTA CORPORATION~~

~~Denial by Regulatory Commissions~~

~~The closing of the acquisition was subject to various conditions, including, among others, receipt of regulatory approval from the WUTC, IPUC, MPSC, OPUC, and the RCA.~~

~~Washington~~ - On March 27, 2018, Avista Corp. and Hydro One filed an all-parties (including the WUTC Staff), all-issues settlement agreement with the WUTC recommending approval of the acquisition of the Company by Hydro One. The settlement agreement was subject to WUTC approval.

On December 5, 2018, the Company and Hydro One received a decision from the WUTC, denying the proposed acquisition. On December 17, 2018, the Company and Hydro One filed a petition requesting that the WUTC reconsider its December 5, 2018 order denying approval of the acquisition, together with a petition requesting that the WUTC rehear the matter to accept new evidence. Under Washington State law, the WUTC had 20 days to act on the petition for reconsideration.

On January 8, 2019, the WUTC provided notice of its deemed denial by operation of law of the filed petition to reconsider the denial of approval for the acquisition. The WUTC did not take action on the petition within the required 20 days of its filing so the petition was automatically denied under the state's Administrative Procedure Act. In the same notice, the WUTC also denied the petition for a rehearing on the basis that it does not apply.

~~Idaho~~ -On April 13, 2018, Avista Corp. and Hydro One filed an all-issues settlement agreement (to which the IPUC Staff was a party) with the IPUC recommending approval of the acquisition of the Company by Hydro One. The settlement agreement was subject to IPUC approval.

~~On January 3, 2019, the Company and Hydro received a decision from the IPUC, finding that the proposed acquisition was not permitted by Idaho law~~. ~~Avista Corp. and Hydro One had until January 24, 2019 to file a petition for reconsideration with the IPUC, which they did not file.~~

~~Oregon~~ - On May 25, 2018, Avista Corp. and Hydro One filed an all-parties (including the OPUC Staff), all-issues settlement agreement with the OPUC related to the Oregon merger proceeding. The settlement agreement was subject to review and approval by the OPUC.

~~On January 15, 2019, due~~Due to the denial of the ~~acquisition~~proposed merger by ~~the WUTC and IPUC, the OPUC issued an order suspending indefinitely the procedural schedule in its merger docket until Hydro One and Avista Corp. informed the OPUC that they had sought a reversal~~certain of the ~~denial decisions through appeal or other means that would provide a justiciable issue for the OPUC to address.~~

~~Termination of the Merger Agreement~~

OnCompany's regulatory commissions, on January 23, 2019, Avista Corp., Hydro One and certain subsidiaries thereof, entered into a Termination Agreement indicating their mutual agreement to terminate the Merger Agreement, effective immediately. Pursuant to the terms of the Termination Agreement, Hydro One paid Avista Corp. a $103 million termination fee on January 24, 2019. The termination fee was used for reimbursing the Company's transaction costs incurred from 2017 to 2019. The balance of the termination fee remaining after payment of 2019 transaction costs and applicable income taxes was used for general corporate purposes and reduced the Company's need for external financing. The 2019 costs totaled $19.7 million pre-tax and included financial advisers' fees, legal fees, consulting fees and employee time.

Other Information Related to the Terminated Acquisition

Due to the termination of the acquisition, all the financial commitments that were included in the various settlement agreements with the commissions for the proposed acquisition will not be required to be performed or observed.

The Company incurred significant transaction costs consisting primarily of consulting, banking fees, legal fees and employee time, and these costs are not being passed through to customers. When the Company was assuming the transaction was going to be completed, a significant portion of these costs were not deductible for income tax purposes. Now that the transaction has been terminated, ~~the Company expects~~ more of the previously incurred transaction costs ~~to be~~are deductible so it ~~expects~~has recorded additional tax benefits from these costs in 2019.

See Note 1516 for discussion of shareholder lawsuits filed against the Company, the Company’s directors, Hydro One, Olympus Holding Corp., and Olympus Corp. in relation to the Merger Agreement and the proposed acquisition.

NOTE ~~18. ASSETS HELD FOR~~19. SALE OF METALfx

In April 2019, Bay Area Manufacturing, Inc., a non-regulated subsidiary of Avista Corp., entered into a definitive agreement to sell its interest in METALfx to an independent third party. The transaction iswas a stock sale for a total cash purchase price of $17.5 million plus cash on-hand, subject to customary closing adjustments. The transaction closed on April 18, 2019, and as of that date the Company has no further involvement with METALfx.

The purchase price of $17.5 million, as adjusted, was divided among the security holders of METALfx, including the minority shareholder, pro rata based on ownership (Avista Corp. owned 89.2 percent of the equity of METALfx). As required under the purchase agreement, $1.2 million (7 percent of the purchase price) will be held in escrow for 24 months from the closing of the transaction to satisfy certain indemnification ~~obligations under the purchase agreement.~~obligations.

When all escrow amounts are released, ~~based on preliminary estimates,~~ the sales transaction is expected to provide cash proceeds to Avista Corp., net of payments to the minority holder, contractually obligated compensation payments and other transaction expenses, of ~~$16.6~~$16.5 million and result in a net gain after-tax of ~~$2.4~~$2.3 million. The Company expects to receive the full amount of its portion of the escrow accounts; therefore, the full amounts are included in the gain calculation. The gross gain is included in "Other income," the transaction expenses paid are included in "Non-utility Other operating expenses" and any taxes associated with the sale are included in "Income tax expense" on the Condensed Consolidated Statements of Income.

Prior to the completion of the sales transaction, METALfx was not a reportable business segment and was included in other in the business segment footnote at Note ~~16. As of March 31, 2019, the assets of METALfx met the criteria for held for sale presentation; however, this~~17. This transaction does not meet the criteria for discontinued operations as it does not represent a strategic shift that will have a major effect on the Company's ongoing operations. The Company elected to present the required held for sale information below, rather than modifying the Condensed Consolidated Balance Sheet. The major classes of assets and liabilities that were held for sale as of March 31, 2019 were as follows (dollars in thousands):operations,

Results of Review of Interim Financial Information

We have reviewed the accompanying condensed consolidated balance sheet of Avista Corporation and subsidiaries (the "Company") as of ~~March 31,~~September 30, 2019, and the related condensed consolidated statements of income, comprehensive income and equity for the three-month and nine-month periods ended September 30, 2019 and 2018 and the related cash flows for the ~~three-month~~nine-month periods ended ~~March 31,~~September 30, 2019 and 2018, and the related notes (collectively referred to as the "interim financial information"). Based on our reviews, we are not aware of any material modifications that should be made to the accompanying interim financial information for it to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2018, and the related consolidated statements of income, comprehensive income, equity, and cash flows for the year then ended (not presented herein); and in our report dated February 19, 2019, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2018, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Basis for Review Results

This interim financial information is the responsibility of the Company's management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our reviews in accordance with standards of the PCAOB. A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

~~The increase in earnings was due to an increase in earnings at Avista Utilities and our other businesses, partially offset by a decrease in earnings at AEL&P.~~

For the year-to-date, Avista Utilities' ~~earnings~~net income increased due to the receipt of a $103 million termination fee from Hydro One (see "Note 18 of the Notes to Condensed Consolidated Financial Statements"), as well as the positive impact of general rate increases and customer growth.

More detailed explanations of the fluctuations are provided in the results of operations and business segment discussions (Avista Utilities, AEL&P, and the other businesses) that follow this section.

General Rate Cases and Regulatory Lag

We expect to experience regulatory lag during the period 2019 through 2021 due to ~~the delay~~our continued investment in utility infrastructure and because we did not file general rate ~~case filings related~~cases during 2018 due to the terminated Hydro One ~~transaction and our continued investment in utility infrastructure. On~~transaction. In April, ~~30, 2019~~ we filed general rates cases in Washington that are two-year rate ~~plans.~~plans (settlement in principle in November 2019, refer to "Regulatory Matters"). We filed an electric only general rate case in Idaho in June that was settled in October 2019 (subject to IPUC approval). We also filed a natural gas general rate case in Oregon in March ~~and we expect to file general rate cases~~(with a settlement approved by the OPUC in ~~Idaho in the second quarter of 2019.~~October 2019). We expect these cases to provide rate relief in ~~early~~ 2020 and ~~begin~~start reducing the regulatory lag that we have been experiencing. Going forward, we will continue to strive to reduce the regulatory timing lag and more closely align our earned returns with those authorized by 2022. This will require adequate and timely rate relief in our jurisdictions. See "Regulatory Matters" for additional discussion of the 2019 general rate cases.

~~Termination of the Proposed Acquisition by Hydro One~~

In July 2017, Avista Corp. entered into a Merger Agreement that provided for Avista Corp. to become an indirect, wholly-owned subsidiary of Hydro One, subject to the satisfaction or waiver of specified closing conditions, including approval by regulatory agencies.

On January 23, 2019, Avista Corp., Hydro One and certain subsidiaries thereof, entered into a termination agreement (Termination Agreement) indicating their mutual agreement to terminate the Merger Agreement, effective immediately. Pursuant to the terms of the Merger Agreement and the Termination Agreement, Hydro One paid Avista Corp. a $103 million

AVISTA CORPORATION

termination fee on January 24, 2019. The termination fee was used for reimbursing our transaction costs incurred from 2017 to 2019. These costs, including income taxes, total approximately $51 million. The balance of the termination fee was used for general corporate purposes and reduced our need for external financing. For further information, see "Note 17 of the Notes to Condensed Consolidated Financial Statements.”

Regulatory Matters

General Rate Cases

We regularly review the need for electric and natural gas rate changes in each state in which we provide service. We expect to continue to file for rate adjustments to:

seek recovery of operating costs and capital investments, and

seek the opportunity to earn reasonable returns as allowed by regulators.

With regards to the timing and plans for future filings, the assessment of our need for rate relief and the development of rate case plans takes into consideration short-term and long-term needs, as well as specific factors that can affect the timing of rate filings. Such factors include, but are not limited to, in-service dates of major capital investments and the timing of changes in major revenue and expense items.

Avista Utilities

Washington General Rate Cases

2015 General Rate Cases

In January 2016 we received an order which was reaffirmed by the WUTC in February 2016 that concluded our electric and natural gas general rate cases originally filed with the WUTC in February 2015. New electric and natural gas rates were effective on January 11, 2016.

The WUTC-approved rates were designed to provide a 1.6 percent, or $8.1 million, decrease in electric base revenue and a 7.4 percent, or $10.8 million, increase in natural gas base revenue. The WUTC also approved an ROR of 7.29 percent, with a common equity ratio of 48.5 percent and a 9.5 percent ROE.

In March 2016, the Public Counsel Unit of the Washington State Office of the Attorney General filed in Thurston County Superior Court a Petition for Judicial Review of the WUTC's orders (described above) that concluded our 2015 electric and natural gas general rate cases. In April 2016, this matter was certified for review directly by the Court of Appeals, an intermediate appellate court in the State of Washington.

On August 7, 2018, the Court of Appeals issued an Opinion which concluded that the WUTC's use of an attrition allowance to calculate Avista Corp.'s rate base violated Washington law. The Court struck all portions of the attrition allowance attributable to Avista Corp.’s rate base and reversed and remanded the case for the WUTC to recalculate Avista Corp.’s rates without including an attrition allowance in the calculation of rate base. On April 17, 2019, the Thurston County Superior Court issued a Remand Order, granting a Joint Motion of Avista Corp., PC and the WUTC to remand the case back to the WUTC. ~~A pre-hearing conference which will set forth the procedural schedule will be held on May 17, 2019.~~

~~The total attrition allowance approved by~~On June 20, 2019, we filed testimony with the WUTC ~~was $35.2~~in the remand case. In our testimony we asserted that the potential amount to return to customers is limited to revenues collected on the basis of rates approved in the 2015 general rate cases, and we also asserted that no refund is due to customers. Subsequent to our filing, other parties in the case filed testimony and asserted that we should refund in the range of approximately $3 million to $77 million to customers. While we do not agree as a legal matter with ~~$28.3~~the positions of the other parties to the case, as a practical matter we believe it is probable that ultimately we will refund some amount to customers. As such, as of September 30, 2019 we have recorded a refund liability of approximately $3 million ~~related~~ to ~~electric and $6.9 million related to natural gas. The Company~~Washington customers. Since we cannot predict the ultimate outcome of this matter at this time, ~~and cannot~~the amount so recorded represents the best current estimate ~~how much, if any,~~ of ~~the attrition allowance may be removed from the general rate cases.~~a potential loss. See "Note 1516 of the Notes to Condensed Consolidated Financial Statements" for further discussion of this matter.

2017 General Rate Cases

On April 26, 2018, the WUTC issued a final order in our electric and natural gas general rate cases that were originally filed on May 26, 2017. In the order, the WUTC approved new electric rates, effective on May 1, 2018, that increased base rates by 2.2 percent (designed to increase electric revenues by $10.8 million). The net increase in electric base rates was made up of an increase in our base revenue requirement of $23.2 million, an increase of $14.5 million in power supply costs and a decrease of $26.9 million for the impacts of the TCJA, which reflects the federal income tax rate change from 35 percent to 21 percent and the amortization of the regulatory liability for plant excess deferred income taxes that was recorded as of December 31, 2017.

While the WUTC authorized an increase in the ERM baseline to reflect increased power supply costs, it directed the parties to examine the functionality and rationale of the Company's power cost modeling and adjust the baseline only in extraordinary circumstances if necessary to more closely match the baseline to actual conditions.

For natural gas, the WUTC approved new natural gas base rates, effective on May 1, 2018, that decreased base rates by 2.4 percent (designed to decrease natural gas revenues by $2.1 million). The net decrease in natural gas base rates was made up of

3941

Table of Contents

AVISTA CORPORATION

an increase in base revenues of $3.4 million that was offset by a decrease of $5.5 million for the impacts from the TCJA, which reflects the federal income tax rate change and the amortization of the regulatory liability for plant-related excess deferred income taxes that was recorded as of December 31, 2017.

In addition to the above, the WUTC also ordered, effective June 1, 2018, a one-year temporary reduction of $7.9 million in our revenue requirements for electric and $3.2 million for natural gas, reflecting reductions for the return of tax benefits associated with the non-plant excess deferred income taxes and the customer refund liability that was established in 2018 related to the change in federal income tax expense for the period January 1, 2018 to April 30, 2018.

The new rates are based on a ROR of 7.50 percent with a common equity ratio of 48.5 percent and a 9.5 percent ROE.

In our original filings, we requested three-year rate plans for electric and natural gas; however, in the final order the WUTC only provided for new rates effective on May 1, 2018.

TCJA Proceedings

In February 2019, we filed an all-party settlement agreement with the WUTC related to the electric tax benefits associated with the TCJA that were set aside for Colstrip in the 2017 general rate case order (effective May 1, 2018). In the settlement agreement, the parties agreed to utilize $10.9 million of the electric tax benefits to offset costs associated with accelerating the depreciation of Colstrip Units 3 & 4, to reflect a remaining useful life of those units through December 31, 2027. That portion of the settlement agreement was denied. The WUTC has indicated that it will review the TCJA and Colstrip in our next general rate case (which was filed on April 30, 2019). ~~The settlement agreement is subject to WUTC approval.~~

2019 General Rate Cases

On April 30, 2019, we filed electric and natural gas general rate cases with the WUTC that are two-year rate plans. We have requested the following electric and natural gas base rate changes each year, which are designed to result in the following increases in annual revenues (dollars in millions):



	Electric				Natural Gas
Effective Date	Revenue Increase		Base Rate Increase		Revenue Increase		Base Rate Increase
April 1, 2020	$	45.8	9.1	%	$	12.9	13.8	%
April 1, 2021	$	18.9	3.5	%	$	6.5	6.1	%

Our requests are based on a proposed ROR of 7.52 percent with a common equity ratio of 50 percent and a 9.9 percent ROE. The WUTC has up to 11 months to review our request and issue a decision.

Under these rate plans, we would not file new general rate cases for new rates to be effective prior to April 1, 2022.

The purpose of our general rate case requests is to recover costs associated with the need to replace infrastructure that has reached the end of its useful life and make technology investments required to build the integrated energy services grid.

Among the projects included in the filing are:

The upgrade of generating units and other equipment at our Little Falls Dam, which will provide more generating capacity.

Our distribution grid modernization program that rebuilds and upgrades electric feeders in the system, replacing old equipment like poles, conductor, and transformers to improve service reliability, capture energy efficiency savings and improve operational ability.

Ongoing management and replacement of electric distribution wood poles through our wood pole management program.

The ongoing project to systematically replace portions of natural gas distribution pipe in our service area that were installed prior to 1987, as well as replacement of other natural gas service equipment.

The rebuild of a high voltage transmission line, including the installation of steel poles and crossarms.

Technology upgrades that support necessary business processes and operational efficiencies.

As a part of these general rate cases, we are also seeking to extend our electric and natural gas decoupling mechanisms for an additional five years (through March 31, 2025). During the second quarter of 2019, we filed a motion to consolidate our ERM filing with our 2019 Washington general rate case and our motion was approved by the WUTC.

A settlement in principle has been reached in the current Washington General Rate Case with all parties and all issues with the exception of decoupling and ERM-related issues. The Settlement Stipulation is in the drafting stage, and the parties, including the Public Counsel Unit of the Washington Attorney General’s Office and the Sierra Club, are securing the necessary approvals in their respective organizations. The Settlement Stipulation is anticipated to be filed on or about November 21, 2019, and will require Commission approval. We believe that the terms of the settlement-in-principle are fair for customers and shareholders.

Idaho General Rate Cases

2017 General Rate Cases

On December 28, 2017, the IPUC approved a settlement agreement between us and other parties to our electric and natural gas general rate cases. New rates were effective on January 1, 2018 and January 1, 2019.

The settlement agreement is a two-year rate plan and has the following electric and natural gas base rate changes each year, which are designed to result in the following increases in annual revenues (dollars in millions):



	Electric				Natural Gas
Effective Date	Revenue Increase		Base Rate Increase		Revenue Increase		Base Rate Increase
January 1, 2018	$	12.9	5.2	%	$	1.2	2.9	%
January 1, 2019	$	4.5	1.8	%	$	1.1	2.7	%

The settlement agreement is based on a ROR of 7.61 percent with a common equity ratio of 50 percent and a 9.5 percent ROE.

As part of the two-year rate plan the Company will not file a new general rate case for a new rate plan to be effective prior to January 1, 2020.

TCJA Proceedings

On May 31, 2018, the IPUC approved an all-party settlement agreement related to the income tax benefits associated with the TCJA. Effective June 1, 2018, ~~through separate tariff schedules, until such time as these changes can be reflected in base rates within the next general rate case,~~ current customer rates were reduced to reflect the reduction of the federal income tax rate to 21 percent, and the amortization of the regulatory liability for plant-related excess deferred income taxes. This reduction reduces annual electric rates by $13.7 million (or 5.3 percent reduction to base rates) and natural gas rates by $2.6 million (or 6.1 percent reduction to base rates).

In March 2019, the IPUC approved an all-party settlement agreement related to the electric tax benefits that were set aside for Colstrip in the 2017 general rate case order. In the approved settlement agreement, the parties agreed to utilize approximately $6.4 million ($5.1 million when tax-effected) of the electric tax benefits to offset costs associated with accelerating the depreciation of Colstrip Units 3 & 4, to reflect a remaining useful life of those units through December 31, 2027. The remaining tax benefits of approximately $5.8 million will be returned to customers through a temporary rate reduction over a period of one year beginning on April 1, 2019. The tax benefits being utilized are related to non-plant excess deferred income taxes, and the customer refund liability that was established in 2018 related to the change in federal income tax expense for the period January 1, 2018 to May 31, 2018.

2019 General Rate Cases

~~We expect~~On October 11, 2019, Avista Corp. and all parties to ~~file~~our electric ~~and natural gas general rate cases with the IPUC in the second quarter of 2019.~~

~~Oregon General Rate Cases~~

~~2019 General Rate Case~~

~~On March 15, 2019 we filed a natural gas~~ general rate case ~~with~~reached a settlement agreement that has been submitted to the ~~OPUC. We have requested an overall increase in~~IPUC for its consideration. If approved, new rates would take effect December 1, 2019.

The proposed rates under the settlement agreement are designed to decrease annual base ~~natural gas rates of 7.8 percent (designed to increase annual natural gas~~electric revenues by ~~$6.7 million). Our~~$7.2 million (or 2.8 percent), effective December 1, 2019. The settlement revenue decreases are based on a 9.5 percent ROE with a common equity ratio of 50 percent and a rate of return ROR on rate base of 7.35 percent, which is a continuation of current levels. This outcome is in line with our expectations.

The primary element of the difference in the agreed upon base revenues in the settlement agreement from our original request is that the settlement includes the continued recovery of costs for our wind generation power purchase agreements, which will include Palouse Wind and Rattlesnake Flat, through the PCA mechanism rather than through base rates.

Our original request included an increase of annual electric base revenues of $5.3 million or 2.1 percent, effective January 1, 2020.

Oregon General Rate Cases

2019 General Rate Case

On October 9, 2019, the OPUC approved the all-party settlement agreements filed in the third quarter of 2019. New rates will take effect on January 15, 2020.

OPUC approved rates designed to increase annual natural gas billed revenues by $3.6 million, or 4.2 percent.

TCJA Proceedings

In February 2019, the OPUC approved the deferral amount of $3.8 million related to 2018 income tax benefits associated with the TCJA. The 2018 deferred benefits will be returned to customers through a temporary rate reduction over a period of one year beginning March 1, 2019. We will continue the deferral of the TCJA benefits during 2019 for later return to customers, until such time as these changes can be reflected in base rates.

Petition for Judicial Review of the Deferral of Capital Projects

In February 2019 and October 2018, the OPUC issued orders which concluded that, contrary to the OPUC's past practice, Oregon statutes that authorize the deferral of expense for later recovery from customers do not authorize the OPUC to allow deferrals of any costs related to capital investments (utility plant). In April 2019, Avista Corp. and other petitioners filed a Petition for Judicial Review with the Oregon Court of Appeals seeking review of the above OPUC orders. The Company cannot predict the outcome of this matter at this time, including whether or not any decision of the court would have retroactive effect.

AMI Project

In March 2016, the WUTC granted our Petition for an Accounting Order to defer and include in a regulatory asset the undepreciated value of our existing Washington electric meters for the opportunity for later recovery. This accounting treatment is related to our plans to replace ~~approximately 253,000 of~~ our existing electric meters with new two-way digital meters and the related software and support services through our AMI project in Washington State. As of ~~March 31,~~September 30, 2019, the estimated future undepreciated value for the existing electric meters ~~is $20.7~~was $21.5 million. In September 2017, the WUTC also approved our request to defer the undepreciated net book value of existing natural gas encoder receiver transmitters (ERT) (consistent with the accounting treatment we obtained on our existing electric meters) that will be retired as part of the AMI project. As of ~~March 31,~~September 30, 2019, the estimated future undepreciated value for the existing natural gas ERTs ~~is $3.8~~was $4.4 million. Replacement of the electric meters and natural gas ERTs began during the second half of 2018 and is ongoing.

In September 2017, the WUTC approved a Petition to defer the depreciation expense associated with the AMI project, along with a carrying charge, and to seek recovery of the deferral and carrying charge in a future general rate case. Cost savings, such as reduced meter reading costs, will occur during the implementation period, and will offset a portion of the AMI costs not being deferred.

In May 2017, we filed Petitions with the IPUC and the OPUC requesting a depreciable life of 12.5 years for the meter data management system (MDM) related to the AMI project. Both the IPUC and the OPUC approved our request. In addition, in connection with the 2017 Idaho electric general rate case (discussed above), the settling parties agreed to cost recovery of Idaho's share of the MDM system, effective January 1, 2019. In connection with the approval of the Oregon general rate case settlement (discussed above), the OPUC approved cost recovery of Oregon's share of the MDM system, effective November 1, 2017.

Avista Utilities

Purchased Gas Adjustments

PGAs are designed to pass through changes in natural gas costs to Avista Utilities' customers with no change in utility margin (operating revenues less resource costs) or net income. In Oregon, we absorb (cost or benefit) 10 percent of the difference between actual and projected natural gas costs included in retail rates for supply that is not hedged. Total net deferred natural

Power Cost Deferrals and Recovery Mechanisms

The ERM is an accounting method used to track certain differences between Avista Utilities' actual power supply costs, net of wholesale sales and sales of fuel, and the amount included in base retail rates for our Washington customers. Under the ERM, Avista Utilities makes an annual filing on or before April 1 of each year to provide the opportunity for the WUTC staff and other interested parties to review the prudence of and audit the ERM deferred power cost transactions for the prior calendar year. See the 2018 Form 10-K for a full discussion of the mechanics of the ERM and the various sharing bands. Total net deferred power costs under the ERM were a liability of ~~$34.8~~$35.5 million as of ~~March 31,~~September 30, 2019, compared to a liability of $34.4 million as of December 31, 2018. These deferred power cost balances represent amounts due to customers. Pursuant to WUTC requirements, should the cumulative deferral balance exceed $30 million in the rebate or surcharge direction, we must make a filing with the WUTC to adjust customer rates to either return the balance to customers or recover the balance from customers.

Under the ERM, Avista Utilities makes an annual filing on or before April 1 of each year to provide the opportunity for the WUTC staff and other interested parties to review the prudence of and audit the ERM deferred power cost transactions for the prior calendar year. The cumulative rebate balance exceeds $30 million and as a result, our 2019 filing contained a proposed rate refund, effective July 1, 2019 over a three-year period. ~~We anticipate filing a motion during~~During the second quarter of 2019 we filed a motion to consolidate this ERM filing with our 2019 Washington general rate case (which was filed on April 30, 2019). In our motion, we ~~will request~~requested that the WUTC withhold the refund associated with the ERM for use in the 2019 general rate case rather than passing it back to customers over the three-year period that was proposed in the ERM filing. Our motion was approved by the WUTC and the ERM refund will now be considered with the 2019 Washington general rate case.

Avista Utilities has a PCA mechanism in Idaho that allows us to modify electric rates on October 1 of each year with IPUC approval. Under the PCA mechanism, we defer 90 percent of the difference between certain actual net power supply expenses and the amount included in base retail rates for our Idaho customers. The October 1 rate adjustments recover or rebate power supply costs deferred during the preceding July-June twelve-month period. Total net power supply costs deferred under the

~~Table of Contents~~

~~AVISTA CORPORATION~~

PCA mechanism were a liability of ~~$3.0~~$1.0 million as of ~~March 31,~~September 30, 2019, compared to a liability of $7.6 million as of December 31, 2018. These deferred power cost balances represent amounts due to customers.

Decoupling and Earnings Sharing Mechanisms

Decoupling (also known as a FCA in Idaho) is a mechanism designed to sever the link between a utility's revenues and consumers' energy usage. In each of our jurisdictions, Avista Utilities' electric and natural gas revenues are adjusted so as to be based on the number of customers in certain customer rate classes and assumed "normal" kilowatt hour and therm sales, rather than being based on actual kilowatt hour and therm sales. The difference between revenues based on the number of customers and "normal" sales and revenues based on actual usage is deferred and either surcharged or rebated to customers beginning in the following year. Only residential and certain commercial customer classes are included in our decoupling mechanisms. See the 2018 Form 10-K for a discussion of the mechanisms in each jurisdiction.

Total net cumulative decoupling deferrals among all jurisdictions were regulatory assets of ~~$9.5~~$25.5 million as of ~~March 31,~~September 30, 2019 and $13.9 million as of December 31, 2018. These decoupling assets represent amounts due from customers. Total net earnings sharing balances among all jurisdictions were regulatory liabilities of ~~$0.9~~$0.7 million as of ~~March 31,~~September 30, 2019 and $1.5 million as of December 31, 2018. These earnings sharing liabilities represent amounts due to customers.

See "Results of Operations - Avista Utilities" for further discussion of the amounts recorded to operating revenues in 2019 and 2018 related to the decoupling and earnings sharing mechanisms.

The following graph shows the total change in net income attributable to Avista Corp. shareholders for the ~~first~~third quarter of 2018 to the ~~first~~third quarter of 2019, as well as the various factors that caused such change (dollars in millions):

Utility revenues decreased at both Avista Utilities and AEL&P.

adoption of the new lease standard on January 1, 2019, which resulted in the reclassification of Snettisham power purchase costs from resource costs to depreciation and amortization and interest expense in 2019. See "Notes 2 and 5 of the Notes to Condensed Consolidated Financial Statements" for further information regarding the adoption of the new lease standard.

The increase in utility other operating expenses was due to an increase at Avista Utilities ~~and a slight increase at AEL&P. The increase at Avista Utilities was the result of~~related to an increase in salaries, pensions and benefits. This was partially offset by a decrease in generation and distribution operating and maintenance ~~costs and employee incentive and benefit~~ costs.

The merger transaction costs are related to the ~~now~~terminated Hydro One acquisition. There were no costs in the third quarter of 2019 because the transaction was terminated in the first quarter of 2019. None of the acquisition costs are being passed through to customers.

Utility depreciation and amortization increased due to additions to utility plant and amortization of the Snettisham finance lease, which was reclassed from utility resource costs to depreciation and amortization, effective January 1, 2019. See "Notes 2 and 5 of the Notes to Condensed Consolidated Financial Statements" for further information regarding the Snettisham lease and the adoption of the new lease standard.

The increase in other was primarily related to a decrease in non-utility other operating expenses due to the sale of METALfx during the second quarter of 2019 and also due to lower property taxes.

Income taxes decreased primarily due to a decrease in income before taxes. Our effective tax rate was negative 2.6 percent for the third quarter of 2019 compared to 13.3 percent for the third quarter of 2018. We expect our full year 2019 effective tax rate

to be approximately 16 percent to 17 percent. See "Note 8 of the Notes to Condensed Consolidated Financial Statements" for further details and a reconciliation of our effective tax rate.

Nine months ended September 30, 2019 compared to the nine months ended September 30, 2018

The following graph shows the total change in net income attributable to Avista Corp. shareholders for the nine months ended September 30, 2018 to the nine months ended September 30, 2019, as well as the various factors that caused such change (dollars in millions):

Utility revenues decreased at both Avista Utilities and AEL&P. Avista Utilities' revenues decreased primarily from a decrease in wholesale electric revenues (due mostly to a decrease in volumes), as well as a decrease in sales of fuel. These items decreased due to lower than normal hydroelectric generation, which resulted in less optimization of the system. These decreases were partially offset by general rate increases and customer growth. AEL&P's revenues decreased from a reduction in sales volumes due to weather that was warmer than normal and warmer than the prior year. Also, there was lower hydroelectric generation at AEL&P which prevented them from making sales to a large interruptible customer.

Utility resource costs decreased at both Avista Utilities and AEL&P. While there was a decrease in gross resource costs at Avista Utilities, there was an increase in power purchase prices, higher thermal fuel costs and lower hydroelectric generation compared to 2018. The decrease at AEL&P was due to a decrease in deferred power supply expenses, as well as the adoption of the new lease standard on January 1, 2019. See "Notes 2 and 5 of the Notes to Condensed Consolidated Financial Statements" for further information regarding the adoption of the new lease standard.

The increase in utility other operating expenses was primarily due to an increase at Avista Utilities primarily related to a donation commitment, which was recorded in the second quarter 2019. There were also increases in generation, transmission and distribution operating and maintenance costs.

The merger transaction costs are related to the terminated Hydro One acquisition. These costs increased for the ~~first quarter of~~year-to-date 2019 ~~because 2019 includes~~related to financial advisers' fees, legal fees, consulting fees and employee time, whereas ~~the first quarter of~~ 2018 consisted primarily of employee time incurred directly related to the transaction. None of the acquisition costs are being passed through to customers.

Utility depreciation and amortization increased due to additions to utility ~~plant.~~plant, amortization of the Snettisham lease (See "Notes 2 and 5 of the Notes to Condensed Consolidated Financial Statements for further information on the Snettisham lease), and from a March 2019 settlement in Idaho, which allowed us to utilize approximately $6.4 million ($5.1 million when tax-effected) of the electric tax benefits to offset costs associated with accelerating the depreciation of Colstrip Units 3 & 4 to reflect a remaining useful life of those units through December 31, 2027. This amount was recorded as a one-time charge to depreciation expense in the second quarter of 2019, with an offsetting amount included in income tax expense.

The merger termination fee was received from Hydro One due to the mutual agreement to terminate the proposed acquisition.

Table of Contents

AVISTA CORPORATION

See "Note 1718 of the Notes to Condensed Consolidated Financial Statements" for additional discussion.

The increase in other was primarily related to the gain on the sale of METALfx during the second quarter of 2019 and a net increase in earnings from our investments. See "Note 19 of the Notes to Condensed Consolidated Financial Statements" for further details of the sales transaction.

Income taxes increased primarily due to increased income before taxes mostly associated with the ~~merger~~receipt of the Hydro One termination fee. Our effective tax rate was ~~20.6~~16.2 percent for ~~the first quarter of~~ 2019, compared to ~~16.3~~16.1 percent for ~~the first quarter of~~ 2018. We expect our full year 2019 effective tax rate to be approximately 16 percent to 17 percent. See "Note 8 of the Notes to Condensed Consolidated Financial Statements" for further details and a reconciliation of our effective tax rate.

The increase in other was primarily because 2018 included an impairment of an investment and additional charges associated with a renovation, whereas the first quarter of 2019 included earnings from our investments.

Non-GAAP Financial Measures

The following discussion for Avista Utilities includes two financial measures that are considered “non-GAAP financial measures”: electric utility margin and natural gas utility margin. In the AEL&P section, we include a discussion of utility margin, which is also a non-GAAP financial measure.

Generally, a non-GAAP financial measure is a numerical measure of a company's financial performance, financial position or cash flows that excludes (or includes) amounts that are included (excluded) in the most directly comparable measure calculated and presented in accordance with GAAP. Electric utility margin is electric operating revenues less electric resource costs, while natural gas utility margin is natural gas operating revenues less natural gas resource costs. The most directly comparable GAAP financial measure to electric and natural gas utility margin is utility operating revenues as presented in "Note 1617 of the Notes to Condensed Consolidated Financial Statements."

The presentation of electric utility margin and natural gas utility margin is intended to enhance the understanding of operating performance. We use these measures internally and believe they provide useful information to investors in their analysis of how changes in loads (due to weather, economic or other conditions), rates, supply costs and other factors impact our results of operations. Changes in loads, as well as power and natural gas supply costs, are generally deferred and recovered from customers through regulatory accounting mechanisms. Accordingly, the analysis of utility margin generally excludes most of the change in revenue resulting from these regulatory mechanisms. We present electric and natural gas utility margin separately below for Avista Utilities since each business has different cost sources, cost recovery mechanisms and jurisdictions, so we believe that separate analysis is beneficial. These measures are not intended to replace utility operating revenues as determined in accordance with GAAP as an indicator of operating performance. Reconciliations of operating revenues to utility margin are set forth below.

The following table presents the current year deferrals and the amortization of prior year decoupling balances that are reflected in utility electric operating revenues for the three months ended ~~March 31~~September 30 (dollars in thousands):


	Electric Operating Revenues						Electric Decoupling Revenues
	2019			2018			2019		2018
Current year decoupling deferrals (a)	$	(2,681	)	$	4,012		$	5,361	$	3,738

Total electric decoupling revenue	$	(1,605	)	$	(868	)	$	5,924	$	(44	)


(a)	Positive amounts are increases in decoupling revenue in the current year and will be surcharged to customers in future years. Negative numbers are decreases in decoupling revenue in the current year and will be rebated to customers in future years.

(b)

Positive amounts are increases in decoupling revenue in the current year and are related to the amortization of rebate balances that resulted in prior years and are being refunded to customers (causing a corresponding decrease in retail revenue from customers) in the current year. Negative numbers are decreases in decoupling revenue in the current year and are related to the amortization of surcharge balances that resulted in prior years and are being surcharged to customers (causing a corresponding increase in retail revenue from customers) in the current year.

Total electric revenues decreased ~~$6.0~~$0.1 million for the ~~first~~third quarter of 2019 as compared to the ~~first~~third quarter of 2018 primarily due to the following:

a ~~$1.1 million~~ ~~increase in retail electric revenue due to an increase in total MWhs sold (increased revenues $8.1 million), partially offset by a decrease in revenue per MWh (decreased revenues $7.0 million).~~


•	a $5.7 million decrease in retail electric revenue due to a decrease in total MWhs sold (decreased revenues $4.0 million) and a decrease in revenue per MWh (decreased revenues $1.7 million).

◦

The ~~increase~~decrease in total retail MWhs sold was primarily the result of ~~weather that was cooler than the prior year (which increased electric heating loads)~~a decrease in industrial sales volumes and a slight decrease in residential sales volumes. These were partially offset by residential and commercial customer growth. Compared to the ~~first~~third quarter of 2018, residential electric use per customer ~~increased 5~~decreased 1 percent and commercial use per customer ~~increased~~decreased 1 percent. Cooling degree days in Spokane were 16 percent below normal and 15 percent below the third quarter of 2018, which resulted in a decrease in cooling loads. Heating degree days in Spokane were 14 percent above normal and 1718 percent above the ~~first~~third quarter of 2018.

◦

The decrease in revenue per MWh was primarily due to a decrease in decoupling rates (as our decoupling surcharges were larger in prior years, which resulted in higher surcharge rates in 2018 as compared to rebates in 2019) and decreases associated with the lower corporate tax rate. This was partially offset by general rate increases in Washington (effective May 1, 2018) and Idaho (effective January 1, 2019).


•	a $5.1 million increase in wholesale electric revenues due to an increase in sales prices (increased revenues $4.5 million) and an increase in sales volumes (increased revenues $0.6 million). The fluctuation in volumes and prices was primarily the result of our optimization activities.


•	a $2.9 million decrease in sales of fuel due to a decrease in sales of natural gas fuel as part of thermal generation resource optimization activities.


•	a $6.0 million increase in electric decoupling revenue. Weather was cooler than normal in the third quarter of 2019, reducing the demand for electric cooling, which resulted in decoupling deferral surcharges related to the current year. There was also the amortization of decoupling rebates from prior years.


•	the $2.8 million decrease in other electric revenues was primarily related to a $1.4 million accrual for customer refunds related to our 2015 Washington general rate case that was remanded back to the WUTC during 2019. See "Regulatory Matters" for further discussion.

(a)	Positive amounts are increases in decoupling revenue in the current year and will be surcharged to customers in future years. Negative numbers are decreases in decoupling revenue in the current year and will be rebated to customers in future years.

(b)

Total natural gas revenues decreased $5.9 million for the third quarter of 2019 as compared to the third quarter of 2018 primarily due to the following:

a $1.7 million increase in natural gas retail revenues due to an increase in volumes (increased revenues $3.9 million), partially offset by lower retail rates (decreased revenues $2.2 million).

◦

Retail natural gas sales increased in the third quarter of 2019 as compared to the third quarter of 2018 primarily due to residential and commercial customer growth and higher use per customer. Compared to third quarter of 2018, residential use per customer increased 9 percent and commercial use per customer increased 15 percent. Heating degree days in Spokane were 14 percent above normal, and 18 percent above the third quarter of 2018. Heating degree days in Medford were 117 percent above normal, and 139 percent above the third quarter of 2018.


◦	Lower retail rates were primarily due to PGAs and decoupling rate decreases (as our decoupling surcharges were larger in prior years, which resulted in higher surcharge rates in 2018 as compared to rebates in 2019), partially offset by general rate increases in Washington (effective May 1, 2018) and Idaho (effective January 1, 2019).


•	a $5.4 million decrease in wholesale natural gas revenues due to a decrease in prices (decreased revenues $9.0 million), partially offset by an increase in volumes (increased revenues $3.6 million). Differences between revenues and costs from sales of resources in excess of retail load requirements and from resource optimization are accounted for through the PGA mechanisms.

the $1.6 million decrease in other natural gas revenues was primarily related to a $1.6 million accrual for customer refunds related to our 2015 Washington general rate case that was remanded back to the WUTC during 2019. See "Regulatory Matters" for further discussion.

Utility Resource Costs

The following graphs present Avista Utilities' resource costs for the three months ended September 30 (dollars in millions):

Total electric resource costs in the graph above include intracompany resource costs of $14.1 million and $12.4 million for the three months ended September 30, 2019 and September 30, 2018, respectively.

Total electric resource costs increased $2.1 million for the third quarter of 2019 as compared to the third quarter of 2018 primarily due to the following:

a $3.1 million increase in power purchased due to an increase in wholesale prices (increased costs $8.9 million), partially offset by a decrease in the volume of power purchases (decreased costs $5.8 million). The fluctuation in volumes and prices was primarily the result of our optimization activities during the quarter.

Total natural gas resource costs in the graph above include intracompany resource costs of $8.5 million and $11.6 million for the three months ended September 30, 2019 and September 30, 2018, respectively.

Total natural gas resource costs decreased $~~19.2~~3.6 million for the third quarter of 2019 as compared to the third quarter of 2018 primarily due to the following:

a $6.0 million decrease in natural gas purchased due to a decrease in the price of natural gas (decreased costs $10.0 million), partially offset by an increase in total therms purchased (increased costs $4.0 million).

a $2.1 million increase from net amortizations and deferrals of natural gas costs.

Electric utility margin decreased $2.2 million and natural gas utility margin decreased $2.3 million.

Electric utility margin decreased primarily due to an increase in net power supply costs due to higher than authorized power purchase prices and thermal fuel costs. For the third quarter of 2019, we had a $2.4 million pre-tax expense under the ERM in Washington, compared to a $0.2 million pre-tax expense for the third quarter of 2018. For the full year of 2019, we expect to be in a benefit position under the ERM within the 75 percent customer/25 percent Company sharing band. Electric utility margin was also negatively affected by an accrual for customer refunds of $1.4 million related to our 2015 Washington general rate case that was remanded back to the WUTC during 2019. See "Regulatory Matters" for further discussion.

Electric utility margin was also positively impacted by a general rate increase in Idaho (effective January 1, 2019), and customer growth.

Natural gas utility margin decreased primarily due to an accrual for customer refunds of $1.6 million related to our 2015 Washington general rate case that was remanded back to the WUTC during 2019. See "Regulatory Matters" for further discussion. This was partially offset by general rate increases in Idaho (effective January 1, 2019), and customer growth.

(b)

Total electric revenues decreased $12.1 million for the nine months ended September 30, 2019 as compared to the nine months ended September 30, 2018 primarily due to the following:

an $8.3 million decrease in retail electric revenue due to a decrease in revenue per MWh (decreased revenues $11.8 million), partially offset by an increase in total MWhs sold (increased revenues $3.5 million).

◦

The increase in total retail MWhs sold was the result of weather that was cooler than the prior year during the first quarter heating season and September 2019 (which increased electric heating loads), and residential and commercial customer growth. Compared to the nine months ended September 30, 2018, residential electric use per customer increased 2 percent and commercial use per customer was relatively consistent. Heating degree days in Spokane were 4 percent above normal and 14 percent above the first nine months of 2018. Year-to-date 2019 cooling degree days were 8 percent below normal and 6 percent below the prior year, which decreased cooling loads.

Electric revenues decreased for the ~~first~~third quarter ofand year-to-date 2019 primarily due to lower sales volumes to residential and commercial customers for 2019 as compared to 2018. This resulted from weather that was warmer than normal and warmer than the prior ~~year.~~year, as well as lower hydroelectric generation, which prevented AEL&P from making sales to an interruptible customer (discussed further below).

Resource costs decreased from the prior year due to the adoption of the new lease standard on January 1, 2019, which resulted in the reclassification of Snettisham power purchase costs from resource costs to depreciation and amortization and interest expense in 2019. See "Notes 2 and 5 of the Notes to Condensed Consolidated Financial Statements" for further information regarding the adoption of the new lease standard. In addition, AEL&P had low hydroelectric generation during the first ~~quarter~~three quarters of 2019, which ~~prevented AEL&P from providing~~limited energy provided to their interruptible customers. A portion of the sales to interruptible customers is used to reduce the overall cost of power to AEL&P's firm customers. When interruptible sales are below a certain threshold, AEL&P recognizes a regulatory asset and records a reduction to deferred power supply costs (resource costs) to reflect a future billable amount to its firm customers when the cost of power rates are reset.

~~For operating expenses, there was a slight increase in other operating expenses for the first quarter of 2019 primarily due to an increase in distribution maintenance costs.~~

The ~~increase~~decrease in net cash provided by operating activities was primarily due to power and natural gas deferrals which increased during 2019 due to higher natural gas prices during the year (which decreased cash flows by $45.8 million) as compared to an increase to operating cash flows of $6.3 million in 2018. As compared to 2018, changes in accounts receivable resulted in a decrease to operating cash flows of $21.3 million.

The above decreases were partially offset by the receipt of the $103.0 million merger termination fee from Hydro One that is reflected in net income for 2019. The termination fee was used for reimbursing our transaction costs incurred from 2017 to 2019 which totaled approximately $51.0 million, including income taxes. The balance of the termination fee was used for general corporate purposes and reduced our

need for external financing. Our total transaction costs were $19.7 million (pre-tax) for 2019 and we also incurred approximately $15.7 million in taxes in 2019 (net of $1.8 million in tax benefits recaptured from 2017 and 2018).

The above increase was partially offset by power and natural gas deferrals which increased during 2019 due to higher natural gas prices during the quarter (which decreased cash flows by $48.1 million) as compared to an increase to operating cash flows of $0.1 million in the first quarter of 2018.

Also, changes in our cash collateral decreased operating cash flows when compared to 2018 because during 2018, our cash collateral posted decreased by $18.4 million, whereas in 2019 it only decreased by $3.4 million. The collateral decreased in both periods primarily due to fluctuations in the fair value of energy commodity derivatives which required less collateral. In addition, ~~outstanding~~we cash settled interest rate swaps ~~in 2018 required less collateral.~~

~~Finally, changes in accounts receivable decreased operating cash flows by $9.8 million~~ during 2019 ~~but increased operating~~and paid a net amount of $13.3 million, compared to net cash ~~flows by $16.0~~paid of $26.6 million for interest rate swap settlements in 2018.

Effective, January 1, 2019, we adopted ASC 842 which resulted in the reclassification of the Snettisham lease from long-term debt, to lease liabilities in 2019. The Snettisham lease amount is included here for this calculation. In addition, operating leases were recorded on the Condensed Consolidated Balance Sheet as of January 1, 2019 and are included here for this calculation. See "Note 5 of the Notes to Condensed Consolidated Financial Statements" for further discussion.

Our shareholders’ equity increased $~~94.1~~120.3 million during the first ~~three~~nine months of 2019 primarily due to net income and the issuance of common stock, partially offset by dividends.

We need to finance capital expenditures and acquire additional funds for operations from time to time. The cash requirements needed to service our indebtedness, both short-term and long-term, reduce the amount of cash flow available to fund capital expenditures, purchased power, fuel and natural gas costs, dividends and other requirements.

Committed Lines of Credit

Avista Corp. has a committed line of credit with various financial institutions in the total amount of $400.0 million that expires in April 2021. As of ~~March 31,~~September 30, 2019, there was ~~$220.9~~$179.5 million of available liquidity under this line of credit.

The Avista Corp. credit facility contains customary covenants and default provisions, including a covenant which does not permit our ratio of “consolidated total debt” to “consolidated total capitalization” to be greater than 65 percent at any time. As of ~~March 31,~~September 30, 2019, we were in compliance with this covenant with a ratio of ~~51.4~~53.7 percent.

AEL&P has a $25.0 million committed line of credit that expires in November 2019. As of ~~March 31,~~September 30, 2019, there were no borrowings or letters of credit outstanding under this committed line of credit.

credit at AEL&P that is expected to be completed during the fourth quarter 2019.

The AEL&P credit facility contains customary covenants and default provisions including a covenant which does not permit the ratio of “consolidated total debt at AEL&P” to “consolidated total capitalization at AEL&P,” (including the impact of the Snettisham obligation) to be greater than 67.5 percent at any time. As of ~~March 31,~~September 30, 2019, AEL&P was in compliance with this covenant with a ratio of ~~52.8~~52.3 percent.

Balances outstanding and interest rates of borrowings under Avista Corp.'s committed line of credit were as follows as of and for the ~~three~~nine months ended ~~March 31~~September 30 (dollars in thousands):

The increase in the average interest rates as of and for the ~~three~~nine months ended ~~March 31,~~September 30, 2019 was primarily the result of a downgrade in our credit rating by Moody's during December 2018. See the 2018 10-K for further discussion of the downgrade by Moody's.

Table of Contents

AVISTA CORPORATION

As of ~~March 31,~~September 30, 2019, Avista Corp. and its subsidiaries were in compliance with all of the covenants of their financing agreements, and none of Avista Corp.'s subsidiaries constituted a “significant subsidiary” as defined in Avista Corp.'s committed line of credit.

Liquidity Expectations

In January 2019, we received a $103 million termination fee from Hydro One in connection with the termination of the proposed acquisition. The termination fee was used for reimbursing our transaction costs incurred from 2017 to 2019. These costs, including income taxes, total approximately $51 million. The balance of the termination fee was used for general corporate purposes and reduced our need for external financing.

In September 2019, we entered into a bond purchase agreement to issue $180.0 million of first mortgage bonds in November 2019. No further long-term debt issuances are planned for 2019. During 2019, we expect to issue ~~approximately $165.0 million of long-term debt and up to $50.0~~$65.0 million of equity ~~in order~~(including $42.9 million issued during the nine months ended September 30, 2019). We intend to use the proceeds from our debt and equity issuances to refinance maturing long-term debt, fund planned capital expenditures, ~~and~~ maintain an appropriate capital ~~structure.~~structure and for other general corporate purposes. This represents an increase from our previous estimates as discussed in the Liquidity section of the 2018 Form 10-K.

After considering the expected issuances of long-term debt and equity during 2019, we expect net cash flows from operating activities, together with cash available under our committed line of credit agreements, to provide adequate resources to fund capital expenditures, dividends, and other contractual commitments.

Capital Expenditures

We are making capital investments to enhance service and system reliability for our customers and replace aging infrastructure. Our ~~estimates~~estimated capital expenditures at Avista Utilities have increased from $405.0 million to $435.0 million for 2019 ~~through 2021 have not materially changed during the three months ended March 31, 2019.~~primarily due to additional spending associated with capital for renewable integration and customer growth. See the 2018 Form 10-K for further ~~information.~~information on our expected capital expenditures.

Off-Balance Sheet Arrangements

As of ~~March 31,~~September 30, 2019, we had $~~60.1~~13.5 million in letters of credit outstanding under our $400.0 million committed line of credit, compared to $10.5 million as of December 31, 2018. The increase in letters of credit outstanding was due to additional letters of credit being issued as collateral for energy commodity derivative instruments.

Pension Plan

Avista Utilities

In the ~~three~~nine months ended~~March 31,~~September 30, 2019 we contributed $~~7.3~~22.0 million to the pension plan and we do not expect ~~to contribute a total of $22.0 million~~further contributions in 2019. We expect to contribute a total of ~~$110.0~~$88.0 million to the pension plan in the period ~~2019~~2020 through 2023, with annual contributions of $22.0 million over that period.

The final determination of pension plan contributions for future periods is subject to multiple variables, most of which are beyond our control, including changes to the fair value of pension plan assets, changes in actuarial assumptions (in particular the discount rate used in determining the benefit obligation), or changes in federal legislation. We may change our pension plan contributions in the future depending on changes to any variables, including those listed above.

Contractual Obligations

Our future contractual obligations have not materially changed during the ~~three~~nine months ended ~~March 31,~~September 30, 2019, except for the following:

a bond purchase agreement of $180.0 million for the issuance and sale of 3.43 percent first mortgage bonds in the fourth quarter of 2019. See "Note 10 of the Notes to Condensed Consolidated Financial Statements" for additional discussion of the bond issuance; and

a contractual obligation for an investment in venture funds that totals $25.0 million over five years.

Environmental Issues and Contingencies

Our environmental issues and contingencies disclosures have not materially changed during the ~~three~~nine months ended ~~March 31,~~September 30, 2019 except for the following:

Colstrip Coal Contract

Colstrip, which is operated by Talen Montana, is supplied with fuel from adjacent coal reserves under coal supply and transportation agreements. The current contract for coal supply extends through 2019; however, the coal mine operator is in bankruptcy and had indicated that it would reject the current contract in its bankruptcy. The co-owners of Colstrip filed objections to the proposed rejection of the coal supply contract and in February 2019, an amended plan of reorganization was filed in which the proposal to reject the coal supply contract was withdrawn. The court approved the amended plan of reorganization on March 2, 2019, which allows the coal supply contract to remain in effect through 2019. The co-owners of Colstrip are in negotiations for an extension to the coal contract beyond 2019 and at the same time are exploring alternative sources for coal supply. Any new arrangements for coal beyond 2019 may have higher costs than the existing coal supply agreement.

Clean Energy Commitment

On April 18, 2019, we announced a goal to serve our customers with 100 percent clean electricity by 2045 and to have a carbon-neutral supply of electricity by the end of 2027. To help achieve ~~these~~our goals and add to our clean electricity portfolio, in the last three years, we have implemented three renewable energy projects on behalf of our customers, the Community Solar project (0.4 MW) in Spokane Valley, Washington (owned by Avista Corp.), the Solar Select project (28 MW) in Lind, Washington (PPA) and the Rattlesnake Flat Wind project (144 MW) in Adams County, Washington (PPA).

To achieve our clean energy goals, we assume that energy storage and other technology which is not currently available or not affordable will advance such that it will allow us to meet our goals while also maintaining reliability and affordability for our customers. If the required technology is not available or not affordable in the future, we may not meet our predetermined goals in the timeframe we have forecasted.

Climate Change - Federal Regulatory Actions

The EPA released the final version of the Affordable Clean Energy (ACE) rule, the replacement for the Clean Power Plan (CPP), in June 2019. EPA’s final rule does not contain any final action on the proposed modifications to the new source review (NSR) program that would provide coal-fired power plants more latitude to make efficiency improvements without triggering pre-construction permit requirements. The final ACE rule combines three distinct EPA actions.

First, EPA finalizes the repeal of the CPP.

Second, the EPA finalizes the ACE rule, which comprises EPA’s determination of the Best System of Emissions Reduction (BSER) for existing coal-fired power plants and establishment of the procedures that will govern States’ promulgation of standards of performance for existing EGUs within their borders. EPA sets the final BSER as heat rate efficiency improvements (HRI) based on a range of “candidate technologies” that can be applied to a plant's operating units and requires that each State determine which apply to each coal-fired unit based on consideration of remaining useful plant life.

Lastly, EPA finalizes a number of changes to the implementing regulations for the timing of State plans for this and future section 111(d) rulemakings. With respect to the Colstrip Generation Station, the Montana Department of Environmental Protection (MDEQ) would initiate the BSER evaluation process. We cannot reasonably predict the timing or outcome of MDEQ’s efforts, or estimate the extent to which Colstrip may be impacted at this time.

Climate Change - State Legislation and State Regulatory Activities

The states of Washington and Oregon have adopted non-binding targets to reduce GHG emissions. Both states enacted their targets with an expectation of reaching the targets through a combination of renewable energy standards, eventual carbon pricing mechanisms, such as cap and trade regulation or a carbon tax, and assorted “complementary ~~policies,~~policies.” ~~but~~However, no specific reductions are ~~mandated.

~~AVISTA CORPORATION~~

Interest Rate Risk

We use a variety of techniques to manage our interest rate risks. We have an interest rate risk policy and have established a policy to limit our variable rate exposures to a percentage of total capitalization. Additionally, interest rate risk is managed by monitoring market conditions when timing the issuance of long-term debt and optional debt redemptions and establishing fixed rate long-term debt with varying maturities. See "Note 6 of the Notes to Condensed Consolidated Financial Statements" for a summary of our interest rate swap derivatives outstanding as of ~~March 31,~~September 30, 2019 and December 31, 2018 and the amount of additional collateral we would have to post in certain circumstances. In addition, see "Regulatory Matters" for a discussion of commitments we made in Oregon surrounding the independent review of our interest rate hedging practices.

Credit Risk

Avista Utilities' contracts for the purchase and sale of energy commodities can require collateral in the form of cash or letters of credit. As of ~~March 31,~~September 30, 2019, we had cash deposited as collateral in the amount of ~~$72.3~~$4.9 million and letters of credit of ~~$56.1~~$9.5 million outstanding related to our energy derivative contracts. Price movements and/or a downgrade in our credit ratings could impact further the amount of collateral required. See “Credit Ratings” in the 2018 Form 10-K for further information. For example, in addition to limiting our ability to conduct transactions, if our credit ratings were lowered to below “investment grade” based on our positions outstanding at ~~March 31,~~September 30, 2019 (including contracts that are considered derivatives and those that are considered non-derivatives), we would potentially be required to post the following additional collateral (in thousands):


	March 31, 2019		September 30, 2019
Additional collateral taking into account contractual thresholds	$	6,900	$	4,162
Additional collateral without contractual thresholds	8,500		4,986

Under the terms of interest rate swap derivatives that we enter into periodically, we may be required to post cash or letters of credit as collateral depending on fluctuations in the fair value of the instrument. As of ~~March 31,~~September 30, 2019, we had interest rate swap derivatives outstanding with a notional amount totaling ~~$245.0~~$215.0 million and we had deposited cash in the amount of ~~$2.9~~$8.9 million as collateral for these interest rate swap derivatives. If our credit ratings were lowered to below “investment grade” based on our interest rate swap derivatives outstanding at ~~March 31,~~September 30, 2019, we would potentially be required to post ~~up to $2.3 million of~~the following additional collateral ~~(with or without contractual thresholds).~~(in thousands):

(1)	Physical transactions represent commodity transactions where we will take or make delivery of either electricity or natural gas; financial transactions represent derivative instruments with delivery of cash in the amount of the benefit or cost but with no physical delivery of the commodity, such as futures, swap derivatives, options, or forward contracts.

The above electric and natural gas derivative contracts will be included in either power supply costs or natural gas supply costs during the period they are delivered and will be included in the various deferral and recovery mechanisms (ERM, PCA, and PGAs), or in the general rate case process, and are expected to eventually be collected through retail rates from customers.

Regional Energy Markets

The California Independent System Operator (CAISO) operates an Energy Imbalance Market (EIM) in the western United States. Most investor-owned utilities in the Pacific Northwest are either participants in the CAISO EIM or plan to integrate into the market in the near future. Factors to be considered in deciding whether to join the CAISO EIM include the amount of variable generating resources in the utilities’ systems, the ability to manage the variable generating resources within the utilities’ systems, the costs associated with joining the CAISO EIM, and the economic benefits associated with joining the CAISO EIM. As additional utilities join the CAISO EIM, there is a reduction in bilateral market liquidity and opportunities for wholesale transactions close to the operating hour. Based on these considerations, we signed an agreement in April 2019 to join the CAISO EIM. We ~~expect to begin~~have begun implementing new processes to enable participation in the EIM in the second half of 2019 and we expect to be full participants by April 2022. We estimate the total cost of joining the EIM to be approximately $25 million for both capital and operating expense spending over the three-year implementation period and we estimate annual benefits of approximately $6 million from market participation. We expect to seek recovery of the net costs through the regulatory process.

Item 4. Controls and Procedures

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

The Company has disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) (Act) that are designed to ensure that information required to be disclosed in the reports it files or submits under the Act is recorded, processed, summarized and reported on a timely basis. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Act is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure. With the participation of the Company’s principal executive officer and principal financial officer, the Company's management evaluated its disclosure controls and procedures as of the end of the period covered by this report. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon this evaluation, the Company’s principal executive officer and principal financial officer have concluded that the Company’s disclosure controls and procedures are effective at a reasonable assurance level as of ~~March 31,~~September 30, 2019.

There have been no changes in the Company's internal control over financial reporting that occurred during the ~~first~~third quarter of 2019 that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

Termination of Individual Change of Control Agreements and adoption of Executive Change of Control Plan.

General

On November 6, 2019, as part of its regular review of compensation and benefits, the Compensation and Organization Committee of the Board of Directors of the Company (the “Committee”) determined that it would be preferable for the Company to have a single change of control plan covering eligible officers rather than separate change of control agreements with each such eligible officer. In connection with this determination, the Board of Directors on November 6, 2019, adopted the Avista Corporation Executive Change of Control Plan (the “Change of Control Plan”), to be effective January 1, 2020.

Certain officers of the Company are presently party to individual change of control agreements with the Company (the “Individual Agreements”). Participation in the Change of Control Plan by an officer with an Individual Agreement is conditioned upon the timely acceptance by such officer of an offer to terminate the Individual Agreement (the “Offer”) in exchange for, among other things, participation in Change of Control Plan.

The description of the Change of Control Plan and the Offers, each set forth below, do not purport to be complete and are qualified in their entireties by reference to the texts of the Change of Control Plan and related Offer letter, each of which is filed as an exhibit to this report.

Offers of Participation in the Change of Control Plan

Officers who are currently parties to Individual Agreements will be offered the opportunity to terminate their Individual Agreements in return for a one-time payment of $75,000 in cash and participation, effective January 1, 2020, in the Change of Control Plan. If the Offer is timely accepted, (i) the $75,000 payment will be made, subject to applicable tax and other withholdings, on or before March 15, 2020, (ii) the Individual Agreement will terminate on December 31, 2019, and (iii) participation in the Change of Control Plan will commence January 1, 2020. The period for accepting the Offer will open on December 1, 2019, and close on December 30, 2019. Officers other than those who are currently subject to Individual Agreements may also be offered participation, effective January 1, 2020, in the Change of Control Plan, though no $75,000 payment will be made to such officers.

Description of Change of Control Plan

Upon a Change of Control (as defined in the Change of Control Plan) and for the 24-month period immediately thereafter (the “Protection Period”), participants’ continued employment with the successor will be governed by the terms of the Change of Control Plan. Annual base salary and target annual bonus opportunities will be no less than as in effect immediately prior to the Change of Control. In addition, officers will be offered employee benefits and other incentive compensation generally available to other similarly-situated officers of the successor.

Upon the occurrence of a termination of employment by the successor without Cause or by the officer for Good Reason (each as defined in the Change of Control Plan), in either case, during the Protection Period, the participant will receive the following benefits, subject to timely execution and return of a general release of claims:

Severance payment. The officer will receive a lump sum cash severance payment, payable on the 60th day following the date of termination in an amount equal to (i) three times the sum of annual base salary and annual target bonus for fiscal year in which the termination of employment occurs for participants who were named executive officers of the Company as of December 31, 2019, and (ii) two times the sum of annual base salary and annual target bonus for fiscal year in which the termination of employment occurs for all other participants.

Prorata target bonus payment. Participants will receive a lump sum cash payment based on the annual target bonus for fiscal year in which the termination of employment occurs, pro-rated to reflect the portion of the fiscal year elapsed prior to the termination of employment and payable on the 60th day following termination of employment.

COBRA Reimbursement. The participants will receive reimbursement for up to 18 months of premiums for COBRA continuation coverage under the successor’s applicable health plan.

The Change of Control Plan does not provide any gross-ups for excise taxes the participant may be subject to with respect to golden parachute payments. In the event the participant would be subject to a 20 percent golden parachute excise tax under Code Section 4999, the payments and benefits to the participant would be reduced to the maximum amount that does not trigger the excise tax, unless the participant would retain greater value (on an after-tax basis) by receiving all payments and benefits and paying the excise tax, in which event the participant would receive the unreduced amount and be subject to the excise tax.

The Change in Control Plan will become effective January 1, 2020.
