     We have not authorized anyone to give you any information other than this prospectus supplement and the accompanying prospectus. You should assume that the information contained or incorporated in this prospectus supplement and the accompanying prospectus is accurate only as of their respective dates. We are not offering to sell these securities and we are not soliciting offers to buy these securities in any jurisdiction in which offers are not permitted.

RISK FACTORS

     Investing in common stock involves risk. You should review all the information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus before deciding to invest. See “Where You Can Find More Information” in the accompanying prospectus. In particular, you should carefully consider the risks and uncertainties discussed in Avista’s Annual Report on Form 10-K incorporated herein by reference in Item 1A “Risk Factors” and under “Forward-Looking Statements” in Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” (all of which may be updated in Quarterly Reports on Form 10-Q filed subsequently to such Annual Report on Form 10-K and incorporated herein by reference).

     In addition to the risks and uncertainties referred to above, there are certain risks associated with the proposed formation of a holding company as discussed under “The Company—Proposed Formation of Holding Company” herein and in the accompanying prospectus. The holding company structure would be accomplished by a statutory share exchange (the “Share Exchange”) whereby each outstanding share of common stock of Avista (“Avista Common Stock”) would be exchanged for one share of common stock of AVA Formation Corp. (“AVA” and “AVA Common Stock”), so that the holders of Avista Common Stock would become holders of AVA Common Stock and Avista would become a subsidiary of AVA. The additional risks associated with the formation of the holding company are described below.

     If the Share Exchange were consummated, AVA’s ability to pay dividends on AVA Common Stock would be subject to the prior rights of holders of AVA indebtedness and preferred stock.

     At the effective time of the Share Exchange, the only class of AVA securities outstanding would be AVA Common Stock. However, AVA may from time to time thereafter issue debt securities and preferred stock, as well as additional shares of AVA Common Stock, in order to make capital contributions to one or more of its subsidiaries, although Avista would likely continue to issue its own debt securities and preferred stock. AVA could also guarantee indebtedness of non-utility subsidiaries. The issuance or guaranty of securities by AVA would not be subject to the prior approval of the state utility commissions or the Federal Energy Regulatory Commission. The consolidated enterprise could thus be more highly leveraged than Avista and its current subsidiaries. AVA’s ability to pay dividends on AVA Common Stock would be subject to the prior rights of holders of AVA debt securities (including guarantees) and preferred stock.

     In addition, the right of AVA, as a shareholder, to receive assets of any of its direct or indirect subsidiaries upon the subsidiary’s liquidation or reorganization would be subject to the prior rights of the holders of existing and future debt securities and preferred stock issued by such subsidiaries, and, as in the case of dividends, the rights of holders of AVA Common Stock to receive any such assets would be subject to the prior rights of the holders of AVA’s debt securities (including guarantees) and preferred stock.

     If the Share Exchange were consummated, AVA’s ability to pay dividends on AVA Common Stock would be dependent on the receipt of the dividends and other payments from AVA’s subsidiaries.

     If the Share Exchange were consummated, AVA would be a holding company and would not have any significant assets other than the shares of common stock of its subsidiaries, and therefore AVA would not produce any operating income of its own. As a result, AVA’s ability to pay its indebtedness and to pay dividends on its capital stock would be dependent on the receipt of dividends and other payments from its subsidiaries.

     Avista and the other companies which would become AVA’s direct and indirect subsidiaries are separate and distinct legal entities, managed by their own boards of directors, and, as is currently the case, would have no obligation to pay any amounts to their respective shareholders, whether through dividends, loans or other payments. The ability of these companies to pay dividends or make other distributions on their common stock is now, and would continue to be, subject to, among other things:

•

their results of operations, cash flows and financial condition, as well as the success of their business strategies and general economic and competitive conditions;

	•		the prior rights of holders of existing and future debt securities and preferred stock issued by those companies; and
	•		any applicable legal restrictions (including any imposed by state regulatory commissions).

SAFE HARBOR FOR FORWARD-LOOKING STATEMENTS

     From time to time we make forward-looking statements such as statements regarding future financial performance, capital expenditures, dividends, capital structure and other financial items, and assumptions underlying them (many of which are based, in turn, upon further assumptions), as well as strategic goals and objectives and plans for future operations. Such statements are made both in our reports filed under the Securities Exchange Act of 1934, as amended, and elsewhere. Forward-looking statements are all statements other than statements of historical fact, including, without limitation, those that are identified by the use of words such as, but not limited to, “will,” “may,” “could,” “should,” “intends,” “plans,” seeks,” “anticipates,” “estimates,” “expects,” “projects,” “predicts” and similar expressions.

     All forward-looking statements are subject to a variety of risks and uncertainties and other factors, most of which are beyond our control and many of which could have a significant impact on our operations, results of operations, financial condition or cash flows and could cause actual results or differ materially from those anticipated in such statements. Such risks, uncertainties and other factors include, among others, those listed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” under “Forward-Looking Statements” in our annual and quarterly reports incorporated herein by reference, as well as those discussed in “Risk Factors” in such reports incorporated herein by reference.

     Our expectations, beliefs and projections are expressed in good faith and are believed by us to have a reasonable basis including, without limitation, management’s examination of historical operating trends, data contained in our records and other data available from third parties. However, there can be no assurance that our expectations, beliefs or projections will be achieved or accomplished. Furthermore, any forward-looking statement speaks only as of the date on which such statement is made. We undertake no obligation to update any forward-looking statement or statements to reflect events or circumstances that occur after the date on which such statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time, and it is not possible for management to predict all of such factors, nor can it assess the impact of each such factor on our business or the extent to which any such factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statement.

THE COMPANY

General

Our corporate headquarters are in Spokane, Washington, center of the Inland Northwest geographic region. Agriculture, mining and lumber were the primary industries in the Inland Northwest for many years; today health care, education, finance, electronic and other manufacturing, tourism and service sectors are growing in importance.

     Avista’s businesses are divided into four segments, as follows:

	•		Avista Utilities - generation, transmission and distribution of electric energy and distribution of natural gas to retail customers, as well as wholesale purchases and sales of electric capacity and energy. This business segment is conducted by an operating division of Avista known as “Avista Utilities.”
	•		Energy Marketing and Resource Management - electricity and natural gas marketing, trading and resource management. This business segment is conducted primarily by Avista Energy, Inc., which is an indirect subsidiary of Avista.
	•		Advantage IQ - facility information and cost management services for multi-site customers. This business segment is conducted by Advantage IQ, Inc., which is an indirect subsidiary of Avista.
	•		Other - includes sheet metal fabrication, radiant floor heating systems and certain real estate investments. This business segment is conducted by various indirect subsidiaries of Avista. Avista intends to limit its future investments in this business segment.

     Avista Energy, Inc., Advantage IQ, Inc. and the various companies in the “Other” business segment are subsidiaries of Avista Capital, Inc., which is a direct, wholly-owned subsidiary of Avista.

Avista Utilities

     Avista Utilities provides electric distribution and transmission as well as natural gas distribution services in parts of eastern Washington and northern Idaho with a population of approximately 865,000. It also provides natural gas distribution service in parts of northeast and southwest Oregon with a population of approximately 470,000. At December 31, 2005, Avista Utilities supplied retail electric service to a total of approximately 338,000 customers and retail natural gas service to a total of approximately 297,000 customers across its entire service territory.

     In addition to providing electric transmission and distribution services, Avista Utilities generates electricity from its generating facilities which have a total net capability of approximately 1,800 megawatts (“MW”). Avista Utilities owns and operates hydroelectric projects having a total net capability of approximately 980 MW, a wood-waste fueled generating station having a net capability of 50 MW, gas-fired generating facilities having a total net capability of 548 MW and an undivided interest in a coal-fired generating station with entitlement to 222 MW of net capability. In addition to its own resources, Avista Utilities is party to a number of long-term power purchase and exchange contracts that increase its available resources.

     Avista Energy operates primarily within the Western Electricity Coordinating Council geographic area, which is comprised of eleven western states as well as the provinces of British Columbia and Alberta, Canada. Avista Energy focuses on optimization of generation assets owned by other entities, long-term electric supply contracts, natural gas storage, and electric transmission and natural gas transportation arrangements. Avista Energy is also involved in trading electricity and natural gas, including derivative commodity instruments.

Advantage IQ

     Advantage IQ’s solutions are designed to provide companies with critical and easy-to-access information that enables them to proactively manage and reduce their utility, telecom and waste management expenses. Its primary product lines include consolidated billing, resource accounting, energy analysis and load profiling services.

Other

     The Other business segment includes several subsidiaries, including Avista Ventures, Inc., Pentzer Corporation, Avista Development and certain other operations of Avista Capital. Included in this business segment is Advanced Manufacturing and Development, a subsidiary of Avista Ventures, Inc.

Proposed Formation of Holding Company

     Avista has entered into a Plan of Share Exchange, dated as of February 13, 2006 (the “Plan of Exchange”), with AVA. Pursuant to the Plan of Exchange, the Share Exchange would be effected whereby each outstanding share of Avista Common Stock (including any shares offered hereby) would be exchanged for one share of AVA Common Stock, so that the holders of Avista Common Stock would become holders of AVA Common Stock and Avista would become a subsidiary of AVA. AVA is expected to change its name before the effective time of the Share Exchange.

     The holders of Avista Common Stock approved the Share Exchange on May 11, 2006. The Federal Energy Regulatory Commission and the Idaho Public Utilities Commission have issued orders authorizing the Share Exchange. Avista also has filed for approval from the utility regulators in Washington, Oregon and Montana. The Share Exchange is subject to the receipt of the remaining regulatory approvals and the satisfaction of other conditions. Avista anticipates that the Share Exchange and the holding company structure implementation, if approved on terms acceptable to Avista, will not be completed earlier than mid-2007.

     See “Description of Common Stock” in the accompanying prospectus for additional information regarding the proposed holding company structure, including a general comparison of Avista Common Stock and AVA Common Stock.

     The offering made by this prospectus supplement will terminate at the effective time of the Share Exchange.

PLAN OF DISTRIBUTION

     Avista has entered into a sales agency agreement, dated as of December 22, 2006, with BNY Capital Markets, Inc. (“BNYCMI”) under which we may issue and sell up to 2,000,000 shares of Avista Common Stock from time to time through BNYCMI, as our agent for the offer and sale of the shares. The sales, if any, of the shares of Avista Common Stock under the sales agency agreement will be made in “at the market” offerings as defined in Rule 415 of the Securities Act of 1933, including sales made directly on the New York Stock Exchange, the principal existing trading market for Avista Common Stock, or through an electronic communications network, or if we and BNYCMI agree in writing, sales made to or through a market maker or in privately negotiated transactions.

     From time to time during the term of the sales agency agreement, and subject to the terms and conditions set forth therein, we may deliver an issuance notice to BNYCMI specifying:

	•		the length of the selling period, which may not exceed 20 trading days;
	•		the number of shares of Avista Common Stock to be sold, which may not exceed 500,000 shares during any selling period without BNYCMI’s prior written consent; and
	•		the minimum price below which sales may not be made.

     Upon receipt of an issuance notice from Avista, and subject to the terms and conditions of the sales agency agreement, BNYCMI has agreed to use its commercially reasonable efforts consistent with its normal trading and sales practices to sell such shares on such terms. We or BNYCMI may suspend the offering of shares Avista Common Stock at any time upon proper notice to the other, and the selling period will immediately terminate. The settlement between us and the purchaser of sales of Avista Common Stock will occur on the third trading day following the date on which the sales were made. The obligation of BNYCMI under the sales agency agreement to sell shares pursuant to any issuance notice is subject to a number of conditions, which BNYCMI reserves the right to waive in its sole discretion.

     We will pay BNYCMI a commission equal to 1% of the sales price of all shares sold through it as agent under the sales agency agreement. We have also agreed to reimburse BNYCMI for its reasonable documented out-of-pocket expenses, including fees and expenses of counsel up to $35,000 in connection with the sales agency agreement.

     In connection with the sale of Avista Common Stock as contemplated herein, BNYCMI may be deemed to be an “underwriter” within the meaning of the Securities Act of 1933, and the compensation paid to BNYCMI may be deemed to be underwriting commissions or discounts. We have agreed to indemnify BNYCMI against certain civil liabilities, including liabilities under the Securities Act of 1933.

     Sales of Avista Common Stock as contemplated herein will be settled through the facilities of The Depository Trust Company or by such other means as the Company and BNYCMI may agree upon.

     The offering of Avista Common Stock pursuant to the sales agency agreement will terminate upon the earliest of (1) the sale of all shares of common stock subject to the sales agency agreement, (2) the third anniversary of the date of the sales agency agreement, (3) the effective time of the Share Exchange referred to under “The Company—Proposed Formation of Holding Company” and (4) any time upon 10 days’ notice. BNYCMI may terminate the sales agency agreement upon one trading day’s notice in certain circumstances, including bankruptcy events relating to us or any material subsidiary, our failure to maintain the listing of Avista Common Stock on the New York Stock Exchange or the occurrence of a material adverse change in Avista.

     We have agreed not to directly or indirectly sell, offer to sell, contract to sell, grant any option to sell or otherwise dispose of, shares of Avista Common Stock or securities convertible into or exchangeable for shares of Avista Common Stock, warrants or any rights to purchase or acquire Avista Common Stock for a period beginning on the first trading day prior to the delivery of any issuance notice to BNYCMI and ending on the first trading day immediately following the last settlement date for Avista Common Stock sold pursuant to the applicable issuance

notice, without the prior written consent of BNYCMI. BNYCMI may give this consent at any time without public notice. The restriction described in this paragraph does not apply to sales of:

	•		shares we offer or sell pursuant to the sales agency agreement;
	•		shares we issue in connection with acquisitions;
	•		shares we issue upon conversion of convertible securities, or the exercise of warrants, options or other rights; or
	•		shares and options to purchase shares we issue, in either case, pursuant to any employee or director stock option or benefit plan, any stock purchase or ownership plan or our dividend reinvestment and direct stock purchase plan.

     BNYCMI and its affiliates have provided investment banking, commercial banking, corporate trust services and other services for us from time to time for which they have received customary fees and reimbursement of expenses and may in the future provide additional services.

     An affiliate of BNYCMI is the Administrative Agent and issuing bank under our committed line of credit. The proceeds of this offering may be used to repay loans outstanding from time to time under the committed line of credit. See “Use of Proceeds” in the accompanying prospectus. Because more than ten percent of the net proceeds of this offering will be paid to members or affiliates of members of the National Association of Securities Dealers, Inc. participating in this offering, this offering will be conducted in accordance with NASD Conduct Rule 2710(h).

LEGAL MATTERS

     The validity of the shares offered hereby and certain other matters will be passed upon for Avista by Dewey Ballantine LLP, counsel to Avista, and Marian M. Durkin, Esq., Senior Vice President, General Counsel and Chief Compliance Officer of Avista. In giving its opinion, Dewey Ballantine LLP may rely as to matters of Washington, Idaho, Montana and Oregon law upon the opinion of Marian M. Durkin, Esq.

EXPERTS

     The consolidated financial statements and management’s report on the effectiveness of internal control over financial reporting incorporated in this prospectus supplement and the accompanying prospectus by reference from the Company’s Annual Report on Form 10-K have been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their reports (which reports (1) express an unqualified opinion on the financial statements and include an explanatory paragraph referring to certain changes in accounting and presentation resulting from the impact of recently adopted accounting standards, (2) express an unqualified opinion on management’s assessment regarding the effectiveness of internal control over financial reporting, and (3) express an unqualified opinion on the effectiveness of internal control over financial reporting) which are herein incorporated by reference, and have been so incorporated in reliance upon the reports of such firm given upon their authority as experts in accounting and auditing.

     With respect to the unaudited interim consolidated financial information, which is incorporated herein by reference, Deloitte & Touche LLP, an independent registered public accounting firm, have applied limited procedures in accordance with the standards of the Public Company Accounting Oversight Board (United States) for a review of such information. However, as stated in their reports included in the Company’s Quarterly Reports on Form 10-Q and incorporated by reference herein, they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their reports on such information should be restricted in light of the limited nature of the review procedures applied. Deloitte & Touche LLP are not subject to the liability provisions of Section 11 of the Securities Act of 1933 for their reports on the unaudited interim financial information because those reports are not “reports” or a “part” of the registration statement prepared or certified by an accountant within the meaning of Sections 7 and 11 of the Act.

General

 

Avista Corporation, which was incorporated in the Territory of Washington in 1889 (sometimes called “Avista”), is an energy company engaged in the generation, transmission and distribution of energy and, through its subsidiaries, in other energy-related businesses. Our corporate headquarters are in Spokane, Washington, center of the Inland Northwest geographic region. Agriculture, mining and lumber were the primary industries in the Inland Northwest for many years; today health care, education, finance, electronic and other manufacturing, tourism and service sectors are growing in importance.

 

Avista’s businesses are divided into four segments, as follows:

 

 

Avista Energy, Inc., Advantage IQ, Inc. and the various companies in the “Other” business segment are subsidiaries of Avista Capital, Inc., which is a direct, wholly-owned subsidiary of Avista Corporation.

Proposed Formation of Holding Company

 

Avista has entered into a Plan of Share Exchange, dated as of February 13, 2006 (the “Plan of Exchange”), with AVA Formation Corp., a wholly-owned subsidiary of Avista (“AVA”). Pursuant to the Plan of Exchange, a statutory share exchange (the “Share Exchange”) would be effected whereby each outstanding share of Avista Common Stock (including any shares offered by this prospectus) would be exchanged for one share of AVA common stock, no par value (“AVA Common Stock”), so that the holders of Avista Common Stock would become holders of AVA Common Stock and Avista would become a subsidiary of AVA. AVA is expected to change its name before the effective time of the Share Exchange.

 

The holders of Avista Common Stock approved the Share Exchange on May 11, 2006. The Federal Energy Regulatory Commission and the Idaho Public Utilities Commission have issued orders authorizing the Share Exchange. Avista also has filed for approval from the utility regulators in Washington, Oregon and Montana. The Share Exchange is subject to the receipt of the remaining regulatory approvals and the satisfaction of other conditions. Avista anticipates that the Share Exchange and the holding company structure implementation, if approved on terms acceptable to Avista, will not be completed earlier than mid-2007.

 

The other outstanding securities of Avista (including any Debt Securities or New Preferred Stock offered by this prospectus) would not be affected by the Share Exchange, with limited exceptions for options and similar securities outstanding under executive compensation and employee benefit plans.

 

Avista expects that, after the effective time of the Share Exchange when AVA becomes the sole holder of Avista Common Stock, Avista will distribute to AVA as a dividend all outstanding shares of Avista Capital. This dividend, which is referred to in this prospectus as the “Avista Capital Dividend”, would effect the structural separation of Avista’s non-regulated businesses from the regulated utility business. A restrictive covenant in the Company’s 9.75% Senior Notes, which mature June 1, 2008, would not permit the Avista Capital Dividend, so that this dividend cannot be made until these notes are retired.

 

Reference is made to the Proxy Statement-Prospectus, dated April 11, 2006, excluding those portions thereof that are deemed “furnished” to, and not “filed” with, the SEC (the “Proxy Statement-Prospectus”), which is incorporated herein by reference, for additional information regarding the proposed formation of the holding company, including, without limitation, information regarding the reasons for forming the holding company and the Avista Capital Dividend, the conditions to the Share Exchange and the expected business, regulation and management of AVA and its subsidiaries after the effective time of the Share Exchange.

 

If the prospectus supplement accompanying this prospectus relates to shares of Avista Common Stock, prospective investors are directed to “Description of Common Stock” herein for additional information regarding the proposed holding company structure, including a general comparison of Avista Common Stock and AVA Common Stock.

 

Unless we indicate differently in a supplement to this prospectus, Avista intends to use the net proceeds from the issuance and sale of the Securities offered by this prospectus for any or all of the following purposes: (a) to fund Avista Utilities’ construction, facility improvement and maintenance programs, (b) to refinance maturing long-term debt, (c) to continue to fund retirements (through redemption, purchase or acquisition) of longer-term debt, (d) to repay short-term debt, (e) to accomplish other general corporate purposes permitted by law and (f) to reimburse Avista’s treasury for funds previously expended for any of these purposes.

 

Avista may issue the Bonds in one or more series, or in one or more tranches within a series. The terms of the Bonds will include those stated in the Mortgage and those made part of the Mortgage by the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The following summary is not complete and is subject in all respects to the provisions of, and is qualified in its entirety by reference to, the Mortgage and the Trust Indenture Act. The Bonds, together with all other debt securities outstanding under the Mortgage, are hereinafter called, collectively,

the “Mortgage Securities”. Avista has filed the Mortgage, as well as a form of supplemental indenture to the Mortgage to establish a series of Bonds, as exhibits to the registration statement of which this prospectus is a part. Capitalized terms used under this heading which are not otherwise defined in this prospectus have the meanings set forth in the Mortgage. Wherever particular provisions of the Mortgage or terms defined in the Mortgage are referred to, those provisions or definitions are incorporated by reference as part of the statements made in this prospectus and those statements are qualified in their entirety by that reference. Sections 125 through 150 of the Mortgage appear in the first supplemental indenture to the Original Mortgage. References to article and section numbers, unless otherwise indicated, are references to article and section numbers of the Mortgage.

 

The applicable prospectus supplement will describe the following terms of the Bonds of each series:

 

 

Payment and Paying Agents

 

Except as may be provided in the applicable prospectus supplement, Avista will pay interest, if any, on each Bond on each interest payment date to the person in whose name such Bond is registered (for purposes of this section of the prospectus, the registered holder of any Mortgage Security is herein referred to as a “Holder”) as of the close of business on the regular record date relating to such interest payment date; provided, however, that Avista will pay interest at maturity (whether at stated maturity, upon redemption or otherwise, “Maturity”) to the person to whom principal is paid.

 

Unless otherwise specified in the applicable prospectus supplement, Avista will pay the principal of and premium, if any, and interest, if any, on the Bonds at Maturity upon presentation of the Bonds at the corporate trust office of Citibank, N.A. in New York, New York, as paying agent for Avista. Avista may change the place of payment of the Bonds, may appoint one or more additional paying agents (including Avista) and may remove any paying agent, all at its discretion.

Registration; Registration of Transfer

 

The Bonds will be issued only in fully registered form. The registered holder of a Bond will be treated as the owner of the Bond for all purposes under the Mortgage. Only registered holders will have rights under the Mortgage. (Mortgage, Sec. 83)

 

The transfer of Bonds may be registered, and Bonds may be exchanged for other Bonds, upon surrender thereof at the principal office of Citibank, N.A., which has been designated by Avista as its office or agency for such purposes. Avista may change such office or agency, and may designate an additional office or agency, in its discretion. No service charge will be made for any registration of transfer or exchange of Bonds, but Avista may require payment of a sum sufficient to cover any tax or other governmental charge incident thereto. Avista will not be required to make any transfer or exchange of any Bonds for a period of 10 days next preceding any selection of Bonds for redemption, nor will it be required to make transfers or exchanges of any Bonds which have been selected for redemption in whole or in part or as to which Avista shall have received a notice for the redemption thereof in whole or in part at the option of the Holder.

 

Redemption

 

The applicable prospectus supplement will indicate the extent, if any, to which the Bonds will be subject to (a) general redemption at the option of Avista or (b) special redemption by the application (either at the option of Avista or pursuant to the requirements of the Mortgage) of (x) cash deposited with the Mortgage Trustee as described under “Special Provisions for Retirement of Bonds” below or (y) cash deposited with the Mortgage Trustee in connection with the release of property from the lien of the Mortgage.

 

Notice of redemption will be given by mail not less than 30 days prior to the date fixed for redemption. (Mortgage, Sec. 52)

 

If less than all the Bonds of a series are to be redeemed, the particular Bonds to be redeemed will be selected by the Mortgage Trustee by lot, according to such method as it shall deem proper in its discretion. (Mortgage, Sec. 52)

 

Any notice of redemption at the option of Avista may state that such redemption will be conditional upon receipt by the Mortgage Trustee, on or before the date fixed for such redemption, of money sufficient to pay the principal of and premium, if any, and interest, if any, on such Bonds and that if such money has not been so received, such notice will be of no force or effect and Avista will not be required to redeem such Bonds. (Mortgage, Sec. 52)

 

Issuance of Additional Mortgage Securities

 

In addition to the Bonds, other debt securities may be issued under the Mortgage. The present principal amount of debt securities which may be outstanding under the Mortgage is $10,000,000,000. However, Avista has reserved the right to amend the Mortgage (without any consent of or other action of Holders of any Mortgage Securities now or hereafter outstanding) to remove this limitation.

 

Mortgage Securities of any series may be issued from time to time on the basis of:

 

 

Property additions generally include electric, natural gas, steam or water property acquired after May 31, 1939, but may not include property used principally for the production or gathering of natural gas. Any such property additions may be used if their ownership and operation is within the corporate purposes of Avista regardless of whether or not Avista has all the necessary permission it may need at any time from governmental authorities to operate such property additions.

The Mortgage provides that no reduction in the book value of the property recorded in the plant account of Avista shall constitute a property retirement, otherwise than in connection with physical retirements of property abandoned, destroyed or disposed of, and otherwise than in connection with the removal of such property in its entirety from the plant account.

 

The Holders of the Bonds will be deemed to have consented to an amendment to the provision of the Mortgage which requires that Avista deliver an opinion of counsel as to the status of the lien of the Mortgage on property additions being certified to the Mortgage Trustee. The amendment would permit us to deliver to the Mortgage Trustee, in lieu of such opinion, title insurance with respect to such property additions in an amount not less than 35% of the cost or fair value to Avista (whichever is less) of such property additions. Such amendment could not be made without the requisite consent of the Holders of outstanding Mortgage Securities as described under “— Modification”.

 

No Mortgage Securities may be issued on the basis of property additions subject to prior liens, unless the prior lien bonds secured thereby have been qualified by being deducted from the Mortgage Securities otherwise issuable and do not exceed 70% of such property additions, and unless the Mortgage Securities then to be outstanding which have been issued against property subject to continuing prior liens and certain other items would not exceed 15% of the Mortgage Securities outstanding.

 

The amount of prior liens on mortgaged property acquired after the date of delivery of the Mortgage may be increased subsequent to the acquisition of such property provided that, if any property subject to such prior lien shall have been made the basis of any application under the Mortgage, all the additional obligation are deposited with the Mortgage Trustee or other holder of a prior lien.

 

(Mortgage, Secs. 4 through 8, 20 through 30 and 46; First Supplemental, Sec. 2; Eleventh Supplemental, Sec. 5; Twelfth Supplemental, Sec. 1; Fourteenth Supplemental, Sec. 4; Seventeenth Supplemental, Sec. 3; Eighteenth Supplemental, Secs. 1, 2 and 6; Twenty-sixth Supplemental, Sec. 2; Twenty-ninth Supplemental, Art. II)

 

Net Earnings Test

 

In general, Avista may not issue Mortgage Securities on the basis of property additions or cash unless net earnings for 12 consecutive months out of the preceding 18 calendar months (before income taxes, depreciation and amortization of property, property losses and interest on any indebtedness and amortization of debt discount and expense) are at least twice the annual interest requirements on all Mortgage Securities at the time outstanding, including the additional issue, and on all indebtedness of prior rank.

 

Avista is not required to satisfy the net earnings requirement prior to the issuance of Mortgage Securities on the basis of retired Mortgage Securities unless:

 

 

In general, the Mortgage permits the inclusion of the following items in net earnings:

 

 

The Mortgage also provides that, in calculating net earnings, no deduction from revenues or other income shall be made for:

 

 

In general, the interest rate requirement with respect to variable interest rate indebtedness, if any, is determined by reference to the rate or rates to be in effect at the time of the initial issuance. However, if any Mortgage Securities or prior ranking indebtedness bears interest at a variable rate, the annual interest requirements thereon shall be determined by reference to the rate or rates in effect on the date next preceding the date of the new issue of Mortgage Securities.

 

Security; Structural Subordination

 

The Bonds, together with all other Mortgage Securities now or hereafter issued under the Mortgage, will be secured by the Mortgage, which constitutes a first mortgage lien on Avista’s facilities for the generation, transmission and distribution of electric energy and the storage and distribution of natural gas and substantially all of Avista’s assets (except as stated below), subject to:

 

 

There are excepted from the lien all cash and securities (including without limitation securities issued by Avista’s subsidiaries); merchandise, equipment, materials or supplies held for sale or consumption in Avista’s operations; receivables, contracts, leases and operating agreements; electric energy, and other material or products (including gas) generated, manufactured, produced or purchased by Avista, for sale, distribution or use in the ordinary course of its business. (Mortgage, Granting Clauses)

 

The Mortgage contains provisions for subjecting to the lien thereof all property (other than property of the kinds excepted from such lien) acquired by Avista after the execution and delivery thereof, subject to purchase money liens and liens existing thereon at the time of acquisition and, subject to limitations in the case of consolidation, merger or sale of substantially all of Avista’s assets. (Mortgage, Granting Clauses and Art. XV)

 

The Mortgage provides that the lien of the Mortgage shall not automatically attach to the properties of another corporation which shall have consolidated or merged with Avista in a transaction in which Avista shall be the surviving or resulting corporation. (Mortgage, Sec. 87)

 

The Mortgage provides that the Mortgage Trustee shall have a lien upon the mortgaged property, prior to the Mortgage Securities, for the payment of its reasonable compensation and expenses and for indemnity. (Mortgage, Secs. 92 and 97; First Supplemental, Art. XXV)

 

Although its utility operations are conducted directly by Avista, all of the other operations of Avista are conducted through its subsidiaries. The lien of the Mortgage does not cover the assets of the subsidiaries or the securities of the subsidiaries held by Avista. Any right of Avista, as a shareholder, to receive assets of any of its direct or indirect subsidiaries upon such subsidiary’s liquidation or reorganization (and the right of the Holders of the Bonds and other creditors of Avista to participate in those assets) is junior to the claims against such assets of that subsidiary’s creditors. As a result, the obligations of Avista to the holders of the Bonds and other creditors are effectively subordinated in right of payment to all indebtedness and other liabilities and commitments (including trade payables and lease obligations) of Avista’s direct and indirect subsidiaries.

Maintenance

 

The Mortgage provides that Avista will cause (or, with respect to property owned in common with others, make reasonable effort to cause) the mortgaged property to be maintained and kept in good repair, working order and condition, and will cause (or, with respect to property owned in common with others, make reasonable effort to cause) to be made such repairs, renewals and replacements of the mortgaged property as, in Avista’s sole judgment, may be necessary to operate the mortgaged property in accordance with common industry practice. Avista may discontinue, or cause or consent to the discontinuance of, the operation and maintenance of any of its properties if such discontinuance is, in the sole judgment of Avista, desirable in the conduct of its business. (Mortgage, Sec. 38)

 

Special Provisions for Retirement of Bonds

 

If, during any 12-month period, any of the mortgaged property is taken by eminent domain and/or sold to any governmental authority and/or sold pursuant to an order of a governmental authority, with the result that Avista receives $15,000,000 or more in cash or in principal amount of purchase money obligations, Avista is required to apply such cash and the proceeds of such obligations (subject to certain conditions and deductions, and to the extent not otherwise applied) to the redemption of Mortgage Securities which are, by their, terms, redeemable before maturity by the application of such cash and proceeds. (Mortgage, Sec. 64; Tenth Supplemental, Sec. 4)

 

Release and Substitution of Property

 

Unless Avista is in default in the payment of the interest on any Mortgage Securities then outstanding under the Mortgage, or a Completed Default shall have occurred and is continuing, Avista may obtain the release from the lien of the Mortgage of any mortgaged property upon the deposit of cash equal to the amount, if any, that the fair value of the property to be released exceeds the aggregate of:

 

(1) the principal amount of any obligations secured by purchase money mortgage upon the property released and delivered to the Mortgage Trustee;

 

(2) the cost or fair value (whichever is less) of property additions which do not constitute funded property, after certain deductions and additions;

 

(3) an amount equal to 10/7^ths of the principal amount of Mortgage Securities that Avista would be entitled to issue on the basis of retired securities (with such entitlement being waived by operation of such release); and

 

(4) the principal amount of obligations secured by purchase money mortgage upon the property released, and/or an amount in cash delivered to the trustee or other holder of a lien prior to the lien of the Mortgage.

 

The use of obligations secured by purchase money mortgage as a credit in connection with the release of property, as described in clauses (1) and (4) above, is subject to the following limitations:

 

(1) the aggregate credit which may be used as described in clauses (1) and (4) above in respect of any property being released may not exceed 70% of the fair value of such property; and

 

(2) the aggregate principal amount of such obligations described in (1) and (4) above and all other obligations secured by purchase money mortgage delivered to the Mortgage Trustee pursuant to said clauses (1) and (4) and then held as part of the mortgaged property by the Mortgage Trustee or the trustee or other holder of a prior lien shall not exceed 40% of the aggregate principal amount of outstanding Mortgage Securities.

 

To the extent that property so released does not constitute funded property, the property additions used to effect the release will not, in certain cases, be deemed to constitute funded property, and the waiver of the right to issue Mortgage Securities to effect the release will, in certain cases, cease to be effective as such a waiver, all upon the satisfaction of certain conditions specified in the Mortgage. The Mortgage contains similar provisions as to cash proceeds of such property. The Mortgage also contains special provisions with respect to prior lien bonds pledged and disposition of moneys received on pledged bonds secured by a prior lien. (Mortgage, Secs. 5; 31, 32, 46 through 50, 59, 60, 61, 118 and 134)

Modification

 

Modifications Without Consent

 

Avista and the Mortgage Trustee may enter into one or more supplemental indentures without the consent of any Holders for any of the following purposes:

 

 

(Mortgage, Sec. 120; Twenty-sixth Supplemental Indenture, Sec. 2; Twenty-ninth Supplemental Indenture, Article II)

 

Modification With Consent

 

In general, the Mortgage, the rights and obligations of Avista and the rights of the Holders may be modified with the consent of 60% in principal amount of the Mortgage Securities outstanding, and, if less than all series of Mortgage Securities are affected, the consent also of 60% in principal amount of the Mortgage Securities of each series affected. However, no modification of the terms of payment of principal or interest, and no modification affecting the lien or reducing the percentage required for modification, is effective against any Holder without its consent. (Mortgage, Art. XVIII, Sec. 149; First Supplemental, Sec. 10)

 

Satisfaction and Discharge

 

Mortgage Securities will be deemed to have been paid for purposes of satisfaction of the lien of the Mortgage if there shall have been irrevocably deposited with the Mortgage Trustee for the payment or redemption of such Mortgage Securities:

 

 

to pay when due the principal of, premium, if any, and interest due and to become due on all outstanding Mortgage Securities on the maturity date or redemption date of such Mortgage Securities. For this purpose, “Government

Obligations” include direct obligations of the government of the United States or obligations guaranteed by the government of the United States. (Mortgage, Sec. 106)

 

The Mortgage Trustee may, and upon request of Avista shall, cancel and discharge the lien of the Mortgage and reconvey the Mortgaged Property to Avista whenever all indebtedness secured thereby has been paid.

 

The right of Avista to cause its entire indebtedness in respect of the Mortgage Securities of any series to be deemed to be satisfied and discharged as described above will be subject to the satisfaction of conditions specified in the instrument creating such series.

 

Completed Defaults

 

Any of the following events will constitute a “Completed Default” under the Mortgage:

 

 

The Mortgage Trustee may withhold notice of default (except in payment of principal, interest or funds for retirement of Mortgage Securities) if it determines that it is in the interest of the Holders. (Mortgage, Secs. 44, 65 and 135)

 

Remedies

 

Acceleration of Maturity

 

If a Completed Default occurs and is continuing, the Mortgage Trustee may, and upon written request of the Holders of a majority in principal amount of Mortgage Securities then outstanding shall, declare the principal of, and accrued interest on, all outstanding Mortgage Securities immediately due and payable; provided, however, that the Holders of a majority in principal amount of outstanding Mortgage Securities may annul such declaration if before any sale of the mortgaged property:

 

 

Possession of Mortgaged Property

 

Under certain circumstances and to the extent permitted by law, if a Completed Default occurs and is continuing, the Mortgage Trustee has the power to take possession of, and to hold, operate and manage, the mortgaged property, or with or without entry, sell the mortgaged property. If the mortgaged property is sold, whether by the Mortgage Trustee or pursuant to judicial proceedings, the principal of the outstanding Mortgage Securities, if not previously due, will become immediately due. (Mortgage, Secs. 66, 67 and 71)

 

Right to Direct Proceedings

 

If a Completed Default occurs and is continuing, the Holders of a majority in principal amount of the Mortgage Securities then outstanding will have the right to direct the time, method and place of conducting any proceedings to be taken for any sale of the mortgaged property, the foreclosure of the Mortgage, or for the appointment of a receiver

or any other proceeding under the Mortgage, provided that such direction does not conflict with any rule of law or with the Mortgage. (Mortgage, Sec. 69)

 

No Impairment of Right to Receive Payment

 

Notwithstanding any other provision of the Mortgage, the right of any Holder to receive payment of the principal of and interest on such Mortgage Security, or to institute suit for the enforcement of any such payment, shall not be impaired or affected without the consent of such Holder. (Mortgage, Sec. 148)

 

Notice of Default

 

No Holder may enforce the lien of the Mortgage unless such Holder shall have given the Mortgage Trustee written notice of a Completed Default and unless the Holders of 25% in principal amount of the Mortgage Securities have requested the Mortgage Trustee in writing to act and have offered the Mortgage Trustee adequate security and indemnity and a reasonable opportunity to act. (Mortgage, Sec. 79)

 

Remedies Limited by State Law

 

The laws of the various states in which the property subject to the lien of the Mortgage is located may limit or deny the ability of the Mortgage Trustee and/or the Holders to enforce certain rights and remedies provided in the Mortgage in accordance with their terms.

 

Concerning the Mortgage Trustee

 

The Mortgage Trustee has, and is subject to, all the duties and responsibilities specified with respect to an indenture trustee under the Trust Indenture Act. Subject to such provisions, the Mortgage Trustee is not under any obligation to take any action in respect of any default or otherwise, or toward the execution or enforcement of any of the trusts created by the Mortgage, or to institute, appear in or defend any suit or other proceeding in connection therewith, unless requested in writing so to do by the Holders of a majority in principal amount of the Mortgage Securities then outstanding. Anything in the Mortgage to the contrary notwithstanding, the Mortgage Trustee is under no obligation or duty to perform any act thereunder (other than the delivery of notices) or to institute or defend any suit in respect hereof, unless properly indemnified to its satisfaction. (Mortgage, Sec. 92)

 

The Mortgage Trustee may at any time resign and be discharged of the trusts created by the Mortgage by giving written notice to Avista and thereafter publishing notice thereof, specifying a date when such resignation shall take effect, as provided in the Mortgage, and such resignation shall take effect upon the day specified in such notice unless a successor trustee shall have previously been appointed by the Holders or Avista and in such event such resignation shall take effect immediately upon the appointment of such successor trustee. The Mortgage Trustee may be removed at any time by the Holders of a majority in principal amount of the Mortgage Securities then outstanding. (Mortgage, Secs. 100 and 101)

 

If Avista appoints a successor trustee and such successor trustee has accepted the appointment, the Mortgage Trustee will be deemed to have resigned as of the date of such successor trustee’s acceptance. (Mortgage, Sec. 102)

 

Evidence of Compliance with Mortgage Provisions

 

Compliance with provisions of the Mortgage is evidenced by written statements of Avista’s officers or persons selected or paid by Avista. In certain matters, statements must be made by an independent accountant or engineer. Various certificates and other papers are required to be filed annually and upon the happening of certain events, including an annual certificate with reference to compliance with the terms of the Mortgage and absence of Completed Defaults.

 

Avista may issue the Notes in one or more series, or in one or more tranches within a series. The terms of the Notes will include those stated in the Indenture and those made part of the Indenture by the Trust Indenture Act. The

following summary is not complete and is subject in all respects to the provisions of, and is qualified in its entirety by reference to, the Indenture and the Trust Indenture Act. The Notes, together with all other debt securities outstanding under the Indenture, are hereinafter called, collectively, the “Indenture Securities”. Avista has filed the Indenture, as well as a form of officer’s certificate to establish a series of Notes, as exhibits to the registration statement of which this prospectus is a part. Capitalized terms used under this heading which are not otherwise defined in this prospectus have the meanings set forth in the Indenture. Wherever particular provisions of the Indenture or terms defined in the Indenture are referred to, those provisions or definitions are incorporated by reference as part of the statements made in this prospectus and those statements are qualified in their entirety by that reference. References to article and section numbers, unless otherwise indicated, are references to article and section numbers of the Indenture.

 

The applicable prospectus supplement or prospectus supplements will describe the following terms of the Notes of each series or tranche:

 

 

Payment and Paying Agents

 

Except as may be provided in the applicable prospectus supplement, Avista will pay interest, if any, on each Note on each interest payment date to the person in whose name such Note is registered (for the purposes of this section of the prospectus, the registered holder of any Indenture Security is herein referred to as a “Holder”) as of the close of business on the regular record date relating to such interest payment date; provided, however, that Avista will pay interest at maturity (whether at stated maturity, upon redemption or otherwise, “Maturity”) to the person to whom principal is paid. However, if there has been a default in the payment of interest on any Note, such defaulted interest may be payable to the Holder of such Note as of the close of business on a date selected by the Indenture Trustee which is not more than 30 days and not less than 10 days before the date proposed by Avista for payment of such defaulted interest or in any other lawful manner not inconsistent with the requirements of any securities

exchange on which such Note may be listed, if the Indenture Trustee deems such manner of payment practicable. (Indenture, Sec. 307)

 

Unless otherwise specified in the applicable prospectus supplement, Avista will pay the principal of and premium, if any, and interest, if any, on the Notes at Maturity upon presentation of the Notes at the corporate trust office of The Bank of New York in New York, New York, as paying agent for Avista. Avista may change the place of payment of the Notes, may appoint one or more additional paying agents (including Avista) and may remove any paying agent, all at its discretion. (Indenture, Sec. 502)

 

Registration; Registration of Transfer

 

The Notes will be issued only in fully registered form. The registered Holder of a Note will be treated as the owner of the Note for all purposes under the Indenture. Only registered Holders will have rights under the Indenture. (Indenture, Sec. 308)

 

Unless otherwise specified in the applicable prospectus supplement, Holders may register the transfer of Notes, and may exchange Notes for other Notes of the same series and tranche, of authorized denominations and having the same terms and aggregate principal amount, at the corporate trust office of The Bank of New York in New York, New York, as security registrar for the Notes. Avista may change the place for registration of transfer and exchange of the Notes, may appoint one or more additional security registrars (including Avista) and may remove any security registrar, all at its discretion. (Indenture, Sec. 502)

 

Except as otherwise provided in the applicable prospectus supplement, no service charge will be made for any transfer or exchange of the Notes, but Avista may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of the Notes. Avista will not be required to execute or to provide for the registration of transfer or the exchange of (a) any Note during a period of 15 days before giving any notice of redemption or (b) any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. (Indenture, Sec. 305)

 

Redemption

 

The applicable prospectus supplement will set forth any terms for the optional or mandatory redemption of Notes. Except as otherwise provided in the applicable prospectus supplement with respect to Notes redeemable at the option of the Holder, Notes will be redeemable by Avista only upon notice by mail not less than 30 nor more than 60 days before the date fixed for redemption. If less than all the Notes of a series, or any tranche thereof, are to be redeemed by Avista, the particular Notes to be redeemed will be selected by such method as shall be provided for such series or tranche, or in the absence of any such provision, by such method of random selection as the Security Registrar deems fair and appropriate. (Indenture, Secs. 403 and 404)

 

Any notice of redemption at the option of Avista may state that such redemption will be conditional upon receipt by the paying agent or agents, on or before the date fixed for such redemption, of money sufficient to pay the principal of and premium, if any, and interest, if any, on such Notes and that if such money has not been so received, such notice will be of no force or effect and Avista will not be required to redeem such Notes. (Indenture, Sec. 404)

 

Unsecured Obligations; Structural Subordination

 

The Indenture is not a mortgage or other lien on assets of Avista or its subsidiaries. In addition to the Notes, other debt securities may be issued under the Indenture, without any limit on the aggregate principal amount. Each series of Indenture Securities will be unsecured and will rank pari passu with all other series of Indenture Securities, except as otherwise provided in the Indenture, and with all other unsecured and unsubordinated indebtedness of Avista Except as otherwise described in the applicable prospectus supplement, the Indenture does not limit the incurrence or issuance by Avista of other secured or unsecured debt, whether under the Indenture, under any other indenture that Avista may enter into in the future or otherwise.

 

Although its utility operations are conducted directly by Avista, all of the other operations of Avista are conducted through its subsidiaries. Any right of Avista, as a shareholder, to receive assets of any of its direct or indirect subsidiaries upon the subsidiary’s liquidation or reorganization (and the right of the Holders and other

creditors of Avista to participate in those assets) is junior to the claims against such assets of that subsidiary’s creditors. As a result, the obligations of Avista to the Holders and other creditors are effectively subordinated in right of payment to all indebtedness and other liabilities and commitments (including trade payables and lease obligations) of Avista’s direct and indirect subsidiaries.

 

Satisfaction and Discharge

 

Any Indenture Securities, or any portion of the principal amount thereof, will be deemed to have been paid for purposes of the Indenture and, at Avista’s election, the entire indebtedness of Avista in respect thereof will be deemed to have been satisfied and discharged, if there shall have been irrevocably deposited in trust with the Indenture Trustee or any paying agent (other than Avista):

 

 

to pay when due the principal of and premium, if any, and interest, if any, due and to become due on such Indenture Securities. For this purpose, “Eligible Obligations” include direct obligations of, or obligations unconditionally guaranteed by, the United States, entitled to the benefit of the full faith and credit thereof and certificates, depositary receipts or other instruments which evidence a direct ownership interest in such obligations or in any specific interest or principal payments due in respect thereof and such other obligations or instruments as shall be specified in an accompanying prospectus supplement. (Indenture, Sec. 601)

 

The right of Avista to cause its entire indebtedness in respect of the Indenture Securities of any series to be deemed to be satisfied and discharged as described above will be subject to the satisfaction of conditions specified in the instrument creating such series.

 

The Indenture will be deemed to have been satisfied and discharged when no Indenture Securities remain outstanding thereunder and Avista has paid or caused to be paid all other sums payable by Avista under the Indenture. (Indenture, Sec. 602)

 

Events of Default

 

Any one or more of the following events with respect to a series of Indenture Securities that has occurred and is continuing will constitute an “Event of Default” with respect to such series of Indenture Securities:

 

 

 

Remedies

 

Acceleration of Maturity

 

If an Event of Default applicable to the Indenture Securities of any series occurs and is continuing, then either the Indenture Trustee or the Holders of not less than 33% in aggregate principal amount of the outstanding Indenture Securities of such series may declare the principal amount (or, if any of the outstanding Indenture Securities of such series are Discount Securities, such portion of the principal amount thereof as may be specified in the terms thereof) of all of the outstanding Indenture Securities of such series to be due and payable immediately by written notice to Avista (and to the Indenture Trustee if given by the Holders); provided, however, that if an Event of Default occurs and is continuing with respect to more than one series of Indenture Securities, the Indenture Trustee or the Holders of not less than 33% in aggregate principal amount of the outstanding Indenture Securities of all such series, considered as one class, may make such declaration of acceleration and not the Holders of any one such series.

 

At any time after such a declaration of acceleration with respect to the Indenture Securities of any series has been made, but before a judgment or decree for payment of the money due has been obtained, such declaration and its consequences will, without further act, be deemed to have been rescinded and annulled, if:

 

 

 

 

Right to Direct Proceedings

 

If an Event of Default with respect to the Indenture Securities of any series occurs and is continuing, the Holders of a majority in principal amount of the outstanding Indenture Securities of such series will have the right to direct the time, method and place of conducting any proceedings for any remedy available to the Indenture Trustee

in exercising any trust or power conferred on the Indenture Trustee; provided, however, that if an Event of Default occurs and is continuing with respect to more than one series of Indenture Securities, the Holders of a majority in aggregate principal amount of the outstanding Indenture Securities of all such series, considered as one class, will have the right to make such direction, and not the Holders of any one of such series; and provided, further, that (a) such direction does not conflict with any rule of law or with the Indenture, and could not involve the Indenture Trustee in personal liability in circumstances where indemnity would not, in the Indenture Trustee’s sole discretion, be adequate and (b) the Indenture Trustee may take any other action deemed proper by the Indenture Trustee which is not inconsistent with such direction. (Indenture, Sec. 712)

 

Limitation on Right to Institute Proceedings

 

No Holder will have any right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or for any other remedy thereunder unless:

 

 

Furthermore, no Holder of any series of Indenture Securities will be entitled to institute any such action if and to the extent that such action would disturb or prejudice the rights of other Holders of such series. (Indenture, Sec. 707)

 

No Impairment of Right to Receive Payment

 

Notwithstanding that the right of a Holder to institute a proceeding with respect to the Indenture is subject to certain conditions precedent, each Holder will have the right, which is absolute and unconditional, to receive payment of the principal of and premium, if any, and interest, if any, on such Indenture Security when due and to institute suit for the enforcement of any such payment. Such rights may not be impaired or affected without the consent of such Holder. (Indenture, Sec. 708)

 

Notice of Default

 

The Indenture Trustee is required to give the Holders notice of any default under the Indenture to the extent required by the Trust Indenture Act, unless such default shall have been cured or waived, except that no such notice to Holders of a default of the character described in the third bulleted paragraph under “— Events of Default” may be given until at least 75 days after the occurrence thereof. For purposes of the preceding sentence, the term “default” means any event which is, or after notice or lapse of time, or both, would become, an Event of Default. The Trust Indenture Act currently permits the Indenture Trustee to withhold notices of default (except for certain payment defaults) if the Indenture Trustee in good faith determines the withholding of such notice to be in the interests of the Holders. (Indenture, Sec. 802)

 

Consolidation, Merger, Sale of Assets and Other Transactions

 

Avista may not consolidate with or merge into any other Person, or convey or otherwise transfer, or lease, all of its properties, as or substantially as an entirety, to any Person, unless:

 

 

 

In the case of the conveyance or other transfer of all of the properties of Avista, as or substantially as an entirety, to any person as contemplated above, Avista would be released and discharged from all obligations under the Indenture and on all Indenture Securities then outstanding unless Avista elects to waive such release and discharge. Upon any such consolidation or merger or any such conveyance or other transfer of properties of Avista, the successor, transferee or lessee would succeed to, and be substituted for, and would be entitled to exercise every power and right of, Avista under the Indenture. (Indenture, Secs. 1001, 1002 and 1003)

 

For purposes of the Indenture, the conveyance, transfer or lease by Avista of all of its facilities (a) for the generation of electric energy, (b) for the transmission of electric energy, (c) for the distribution of electric energy and/or natural gas, in each case considered alone, (d) all of its facilities described in clauses (a) and (b), considered together, or (e) all of its facilities described in clauses (b) and (c), considered together, will in no event be deemed to constitute a conveyance or other transfer of all the properties of Avista, as or substantially as an entirety, unless, immediately following such conveyance, transfer or lease, Avista owns no unleased properties in the other such categories of property not so conveyed or otherwise transferred or leased.

 

The Indenture will not prevent or restrict:

 

 

If Avista conveys or otherwise transfers any part of its properties which does not constitute the entirety, or substantially the entirety, thereof to another Person meeting the requirements set forth in the first paragraph under this heading, and if:

 

 

then Avista would be released and discharged from all obligations and covenants under the Indenture and on all Indenture Securities then outstanding unless Avista elects to waive such release and discharge. In such event, the transferee would succeed to, and be substituted for, and would be entitled to exercise every right and power of, Avista under the Indenture. (Indenture, Sec. 1005)

 

Modification of Indenture

 

Modifications Without Consent

 

Avista and the Indenture Trustee may enter into one or more supplemental indentures, without the consent of any Holders, for any of the following purposes:

 

 

 

Without limiting the generality of the foregoing, if the Trust Indenture Act is amended after the date of the Original Indenture in such a way as to require changes to the Indenture or the incorporation therein of additional provisions or so as to permit changes to, or the elimination of, provisions which, at the date of the Original Indenture or at any time thereafter, were required by the Trust Indenture Act to be contained in the Indenture, the Indenture will be deemed to have been amended so as to conform to such amendment or to effect such changes or elimination, and Avista and the Indenture Trustee may, without the consent of any Holders, enter into one or more supplemental indentures to evidence or effect such amendment. (Indenture, Sec. 1101)

 

Modifications Requiring Consent

 

Except as provided above, the consent of the Holders of a majority in aggregate principal amount of the Indenture Securities of all series then outstanding, considered as one class is required for the purpose of adding any provisions to, or changing in any manner, or eliminating any of the provisions of, the Indenture pursuant to one or more supplemental indentures; provided, however, that if less than all of the series of Indenture Securities outstanding are directly affected by a proposed supplemental indenture, then the consent only of the Holders of a majority in aggregate principal amount of outstanding Indenture Securities of all series so directly affected, considered as one class, will be required; and provided, further, that if the Indenture Securities of any series have been issued in more than one tranche and if the proposed supplemental indenture directly affects the rights of the Holders of one or more, but less than all, of such tranches, then the consent only of the Holders of a majority in

aggregate principal amount of the outstanding Indenture Securities of all tranches so directly affected, considered as one class, will be required; and provided, further, that no such amendment or modification may:

 

 

A supplemental indenture which changes or eliminates any covenant or other provision of the Indenture which has expressly been included solely for the benefit of the Holders of, or which is to remain in effect only so long as there shall be outstanding, Indenture Securities of one or more specified series, or one or more tranches thereof, or modifies the rights of the Holders of such series or tranche with respect to such covenant or other provision, will be deemed not to affect the rights under the Indenture of the Holders of any other series or tranche.

 

If the supplemental indenture or other document establishing any series or tranche of Indenture Securities so provides, and as specified in the applicable prospectus supplement and/or pricing supplement, the Holders of such Indenture Securities will be deemed to have consented, by virtue of their purchase of such Indenture Securities, to a supplemental indenture containing the additions, changes or eliminations to or from the Indenture which are specified in such supplemental indenture or other document. No Act of such Holders will be required to evidence such consent and such consent may be counted in the determination of whether the Holders of the requested principal amount of Indenture Securities have consented to such supplemental indenture. (Indenture, Sec. 1102)

 

Duties of the Indenture Trustee; Resignation; Removal

 

The Indenture Trustee will have, and will be subject to, all the duties and responsibilities specified with respect to an indenture trustee under the Trust Indenture Act. Subject to such provisions, the Indenture Trustee will be under no obligation to exercise any of the powers vested in it by the Indenture at the request of any Holder, unless such Holder offers it reasonable indemnity against the costs, expenses and liabilities which might be incurred thereby. The Indenture Trustee will not be required to expend or risk its own funds or otherwise incur personal financial liability in the performance of its duties if the Indenture Trustee reasonably believes that repayment or adequate indemnity is not reasonably assured to it. (Indenture, Secs. 801 and 803)

 

The Indenture Trustee may resign at any time with respect to the Indenture Securities of one or more series by giving written notice thereof to Avista or may be removed at any time with respect to the Indenture Securities of one or more series by Act of the Holders of a majority in principal amount of the outstanding Indenture Securities of such series delivered to the Indenture Trustee and Avista. No resignation or removal of the Indenture Trustee and no appointment of a successor trustee will become effective until the acceptance of appointment by a successor trustee in accordance with the requirements of the Indenture. So long as no Event of Default or event which, after notice or lapse of time, or both, would become an Event of Default has occurred and is continuing, if Avista has delivered to the Indenture Trustee with respect to one or more series a resolution of its Board of Directors appointing a successor

trustee with respect to that or those series and such successor has accepted such appointment in accordance with the terms of the Indenture, the Indenture Trustee with respect to that or those series will be deemed to have resigned and the successor will be deemed to have been appointed as trustee in accordance with the Indenture. (Indenture, Sec. 810)

 

Evidence of Compliance

 

Compliance with the Indenture provisions is evidenced by written statements of Avista officers or persons selected or paid by Avista. In certain cases, Avista must furnish opinions of counsel and certifications of an engineer, appraiser or other expert (who in some cases must be independent). In addition, the Indenture requires that Avista give the Indenture Trustee, not less than annually, a brief statement as to Avista’s compliance with the conditions and covenants under the Indenture.

 

Governing Law

 

The Indenture and the Indenture Securities will be governed by and construed in accordance with the laws of the State of New York, except to the extent that the Trust Indenture Act shall be applicable.

 

General

 

The authorized capital stock of Avista Corporation, as set forth in its Restated Articles of Incorporation, as amended (“Avista Articles”), consists of 10,000,000 shares of Preferred Stock, cumulative, without nominal or par value, which is issuable in series, and 200,000,000 shares of Common Stock, without nominal or par value, together with attached preferred share purchase rights. Following is a brief description of certain of the rights and privileges of the Preferred Stock.

 

Avista may issue shares of New Preferred Stock in one or more additional series. The terms of the New Preferred Stock will include those stated in the Avista Articles and in Avista’s Bylaws (“Avista Bylaws”) and those made applicable thereto by the Washington Business Corporation Act (the “Washington BCA”). The following summary is not complete and is subject in all respects to the provisions of, and is qualified in its entirety by reference to, the Avista Articles, the Avista Bylaws and the Washington BCA. Avista has filed the Avista Articles, as well as a form of amendment thereto to establish a series of New Preferred Stock, and the Avista Bylaws as exhibits to the registration statement of which this prospectus is a part. Whenever particular provisions of the Avista Articles or the Avista Bylaws are referred to, those provisions are incorporated by reference as part of the statements made in this prospectus and those statements are qualified in their entirety by that reference.

 

The Avista Articles provide that the Preferred Stock may be divided into and issued from time to time in one or more series. All shares of Preferred Stock constitute one and the same class of stock, are of equal rank and will otherwise be identical except as to the designation thereof, the date or dates from which dividends on shares thereof will be cumulative, and except that each series may vary as to, and the applicable prospectus supplement will describe:

 

 

When Preferred Stock is initially issued, the number of shares constituting such series, its distinguishing serial designation and its particular characteristics (insofar as there may be variations between series) may be fixed by resolution of the Board of Directors.

 

Dividend Rights

 

The New Preferred Stock of each series will be entitled, on a parity with each other series of Preferred Stock and in preference to the Common Stock, to receive, but only when and as declared by the Board of Directors, dividends at the rate determined for such series and set forth in the applicable prospectus supplement. Such dividends will be cumulative from the date of issuance of the New Preferred Stock and will be payable on the fifteenth day of March, June, September and December in each year, except as otherwise provided in the applicable prospectus supplement.

 

Liquidation Rights

 

The New Preferred Stock of each series will be entitled, upon dissolution or liquidation, on a parity with each other series of Preferred Stock and in preference to the Common Stock, to a liquidation preference per share determined for such series plus an amount equivalent to accrued and unpaid dividends thereon, if any, to the date of such event. The liquidation preference of each series of New Preferred Stock will be set forth in the applicable prospectus supplement.

 

Voting Rights

 

Except for those purposes for which the right to vote is expressly conferred by the Avista Articles or the Washington BCA, the holders of Preferred Stock have no power to vote.

 

Under the Avista Articles, whenever and as often as, at any date, dividends payable on any shares of Preferred Stock (including any New Preferred Stock) shall be in arrears in an amount equal to the aggregate amount of dividends accumulated on such shares over the eighteen (18) month period ended on such date, the holders of the Preferred Stock, voting separately and as a single class, are entitled to elect a majority of the Board of Directors, and the holders of the Common Stock, voting separately and as a single class, shall be entitled to elect the remaining directors. Such voting rights of the holders of the Preferred Stock cease when all defaults in the payment of dividends on the Preferred Stock of any and all series have been cured.

 

In addition, under the Avista Articles the affirmative vote of the holders of at least a majority of the shares of the Preferred Stock is required:

 

(a) for the adoption of any amendment of the Avista Articles which would: (i) create or authorize any new class of stock ranking prior to or on a parity with the Preferred Stock as to dividends or upon dissolution, liquidation or winding up; (ii) increase the authorized number of shares of the Preferred Stock; or (iii) change any of the rights or preferences of the Preferred Stock at the time outstanding, provided that if any such change would affect the holders of less than the Preferred Stock of all series then outstanding, only the affirmative vote of the holders of at least a majority of the shares of all series so affected is required; and

 

(b) for the issuance of Preferred Stock, or of any other class of stock ranking prior to or on a parity with such Preferred Stock as to dividends or upon dissolution, liquidation or winding up, unless the net income of Avista available for the payment of dividends for a period of 12 consecutive calendar months within the 15 calendar months immediately preceding the issuance of such shares is at least equal to one and one-half times the annual dividend requirements on shares of Preferred Stock and on all shares of all other classes of stock ranking prior to or on a parity with the Preferred Stock as to dividends or upon dissolution, liquidation or winding up, which will be outstanding immediately after the issuance of such shares, including the shares proposed to be issued; provided, however, that if the shares of Preferred Stock or any such prior or parity stock shall have a variable dividend rate, the annual dividend requirement of such shares shall be determined by reference to the weighted average dividend rate on such shares during the 12-month period for which the net income of Avista available for the payment of dividends shall have been determined; and provided, further, that

if the shares of the series to be issued are to have a variable dividend rate, the annual dividend requirement on such shares shall be determined by reference to the initial dividend rate upon the issuance of such shares.

 

Under the Washington BCA, a vote of the holders of a majority of the outstanding shares of Preferred Stock is required in connection with certain changes in the capital structure of Avista or in certain rights and preferences of the Preferred Stock, including certain of the changes described in (a) above. In addition, the Washington BCA requires the approval of certain mergers, share exchanges (but not the Share Exchange presently contemplated) and other major corporate transactions by the holders of two-thirds of the outstanding Preferred Stock.

 

Pre-emptive Rights

 

No holder of Preferred Stock has any pre-emptive rights.

 

Miscellaneous

 

The Avista Articles contain no restriction on the redemption or repurchase by Avista of shares of Preferred Stock while there is any arrearage in the payment of dividends on, or sinking fund payments in respect of, the Preferred Stock.

 

Upon issuance as contemplated by this prospectus and the applicable prospectus supplement, the New Preferred Stock will be fully paid and nonassessable. The holders of the New Preferred Stock will not be subject to liability for further calls or assessment by, or for liabilities of, Avista.

 

General

 

The authorized capital stock of Avista, as set forth in its Restated Articles of Incorporation, as amended, consists of 10,000,000 shares of Preferred Stock, cumulative, without nominal or par value, which is issuable in series, and 200,000,000 shares of Common Stock without nominal or par value, together with attached preferred share purchase rights. Following is a brief description of certain of the rights and privileges of the Common Stock.

 

Avista may issue additional shares of its Common Stock from time to time. The terms of the Common Stock include those stated in the Avista Articles and the Avista Bylaws and those made applicable thereto by the Washington BCA. The following summary is not complete and is subject in all respects to the provisions of, and is qualified in its entirety by reference to, the Avista Articles, the Avista Bylaws and the Washington BCA. Avista has filed the Avista Articles and the Avista Bylaws as exhibits to the registration statement of which this prospectus forms a part. Whenever particular provisions of the Avista Articles or the Avista Bylaws are referred to, those provisions are incorporated as part of the statements made in this prospectus and those statements are qualified in their entirety by that reference.

 

Dividend Rights

 

After full provision for all Preferred Stock dividends declared or in arrears, the holders of Common Stock are entitled to receive such dividends as may be lawfully declared from time to time by Avista’s Board of Directors.

 

The Indenture, dated as of April 3, 2001, between Avista and The Bank of New York, as successor trustee, under which $272,860,000 of senior unsecured notes were outstanding as of November 30, 2006, contains restrictions on the payment of dividends. So long as there is no default under the Indenture, Avista does not expect these restrictions to limit its ability to pay dividends on its capital stock. These notes mature on June 1, 2008.

 

Voting Rights

 

The holders of the Common Stock have sole voting power, except as indicated below or as otherwise provided by law. Each holder of Common Stock is entitled to one vote per share, except that, in the election of directors, each holder has “cumulative” voting rights by which such holder is entitled to that number of votes which is equal to the

number of directors to be elected multiplied by the number of shares held. These votes may all be cast for a single nominee for director or may be distributed among any two or more nominees.

 

Under the Avista Articles, whenever and as often as, at any date, dividends payable on any shares of Preferred Stock (including any New Preferred Stock) shall be in arrears in an amount equal to the aggregate amount of dividends accumulated on such shares of Preferred Stock over the eighteen (18) month period ended on such date, the holders of the Preferred Stock, voting separately and as a single class, are entitled to elect a majority of the Board of Directors, and the holders of the Common Stock, voting separately and as a single class, will be entitled to elect the remaining directors. Such voting rights of the holders of the Preferred Stock cease when all defaults in the payment of dividends on the Preferred Stock have been cured.

 

In addition, the consent of various proportions of the Preferred Stock at the time outstanding is required to adopt any amendment to the Articles which would authorize any new class of stock ranking prior to or on a parity with the Preferred Stock as to certain matters, to increase the authorized number of shares of the Preferred Stock, to change any of the rights or preferences of outstanding Preferred Stock or to issue additional shares of Preferred Stock unless an earnings test is satisfied.

 

Classified Board of Directors

 

Both the Avista Articles and the Avista Bylaws provide for a Board of Directors divided into three classes. Each director of a class will generally serve for a term of three years, with only one class of directors being elected in each year. The classification of the Board of Directors reduces the impact of cumulative voting rights.

 

The Avista Articles and Avista Bylaws also generally provide that directors may be removed only for cause and only by the affirmative vote of the holders of at least a majority of the outstanding shares of Common Stock. The Avista Articles and Avista Bylaws further require an affirmative vote of the holders of at least 80% of the outstanding shares of Common Stock to alter, amend or repeal the provisions relating to the classification of the Board of Directors and the removal of members from, and the filling of vacancies on, the Board of Directors.

 

“Fair Price” Provision

 

The Avista Articles contain a “fair price” provision which requires the affirmative vote of the holders of at least 80% of the outstanding shares of Common Stock for the consummation of certain business combinations, including mergers, consolidations, recapitalizations, certain dispositions of assets, certain issuances of securities, liquidations and dissolutions involving Avista and a person or entity who is or, under certain circumstances, was, a beneficial owner of 10% or more of the outstanding shares of Common Stock (an “Interested Shareholder”) unless

 

 

Preferred Share Purchase Rights

 

General

 

Reference is made to the Rights Agreement, dated as of November 15, 1999 (the “Rights Agreement”) between Avista and The Bank of New York, as Rights Agent, filed with the SEC. The following statements are qualified in their entireties by such reference.

 

On November 12, 1999, the Avista Board of Directors authorized the Rights Agreement to replace the then-existing rights plan which expired on February 16, 2000. Under the Rights Agreement, Avista granted one preferred share purchase right (a “Right”) on each outstanding share of Common Stock to holders of Common Stock outstanding on February 15, 2000 or issued thereafter. The description and terms of Rights are set forth in the Rights Agreement.

Each Right entitles the registered holder, subject to regulatory approvals and other specified conditions, to purchase one one-hundredth of a share of Preferred Stock at a purchase price of $70.00 (the “Purchase Price”). The Rights are exercisable only if a person or group

 

 

Until that time, the Rights are evidenced by and trade with the shares of Common Stock. Each right was originally scheduled to expire on March 31, 2009. However, in connection with the execution by Avista of the Plan of Exchange, the Rights Agreement was amended to provide that the Rights will expire upon the earlier of the effective time of the Share Exchange (as described below) and March 31, 2009.

 

The purchase of stock pursuant to the Rights may be subject to regulatory approvals and other specified conditions. Under no circumstances will a person or group that acquires 10% of the Common Stock be entitled to exercise Rights.

 

“Flip-in”

 

If any person or group acquires beneficial ownership of 10% or more of the outstanding shares of Common Stock, each unexercised Right will entitle its holder to purchase that number of shares of Common Stock or, at the option of Avista, Preferred Stock, which has a market value at that time of twice the Purchase Price.

 

“Flip-over”

 

In the event that any person or group has acquired beneficial ownership of 10% or more of the outstanding shares of Common Stock, and Avista

 

 

any person or group, each unexercised Right would instead entitle its holder to purchase the acquiring company’s common shares having a market value of twice the Purchase Price.

 

Exchange

 

If a person or group acquires beneficial ownership of more than 10% but less than 50% of the outstanding shares of Common Stock, Avista may exchange each outstanding Right for one share of Common Stock or cash, securities or other assets having a value equal to the market value of one share of Common Stock. That exchange may be subject to regulatory approvals.

 

Redemption

 

Avista may redeem the Rights, at a redemption price of $0.01 per Right, at any time until any person or group has acquired beneficial ownership of 10% or more of the outstanding shares of Common Stock.

 

Certain Adjustments

 

The Purchase Price, the amount and type of securities covered by each Right and the number of Rights outstanding will be adjusted to prevent dilution:

 

 

 

With certain exceptions, no adjustments in the Purchase Price will be made until cumulative adjustments amount to at least 1% of the Purchase Price. Avista will not issue fractional shares of Preferred Stock other than in integral multiples of one ten-thousandth of a share. Instead, Avista will make an adjustment in cash based on the market price of the Preferred Stock on the last trading date prior to the date of exercise.

 

Amounts Outstanding

 

Avista distributed one Right to its shareholders for each share of Common Stock owned of record by them at the close of business on February 15, 2000. Until the earliest of

 

 

Avista has issued and will continue to issue one Right with each share of Common Stock that is issued after February 15, 2000 so that each outstanding share of Common Stock has and will continue to have an appurtenant Right. Avista has initially authorized and reserved 600,000 shares of Preferred Stock for issuance upon exercise of the Rights.

 

Amendment

 

Avista may amend the Rights Agreement in any respect until any person or group has acquired beneficial ownership of 10% or more of the outstanding shares of Common Stock. Thereafter, Avista may amend the Rights Agreement in any manner which will not adversely affect the holders of the Rights in any material respect.

 

Statutory Limitation on “Significant Business Transactions”

 

General

 

The Washington BCA contains provisions that limit our ability to engage in “significant business transactions” with an “acquiring person”, each as defined below. We have no right to waive the applicability of these provisions.

 

Significant Business Transactions Within Five Years of Share Acquisition Time

 

Subject to certain exceptions, for five years after an “acquiring person’s” “share acquisition time”, Avista may not engage in any “significant business transaction” with such “acquiring person” unless, before such “share acquisition time”, a majority of the Board of Directors approves either:

 

 

Significant Business Transactions More Than Five Years After Share Acquisition Time

 

Avista may not engage in certain “significant business transactions” (including mergers, share exchanges and consolidations) with any “acquiring person” unless:

 

 

Definitions

 

As used in this section:

 

“Significant business transaction” means any of various specified transactions involving an “acquiring person”, including:

 

 

“Acquiring person” means, with certain exceptions, a person (or group of persons) other than Avista or its subsidiaries who beneficially owns 10% or more of the outstanding Common Stock of Avista.

 

“Share acquisition time” means the time at which a person first becomes an “acquiring person” of Avista.

 

Anti-Takeover Effect

 

The provisions of the Avista Articles and the Avista Bylaws described above under “Classified Board of Directors” and “‘Fair Price’ Provision” and the Rights Agreement described above under “Preferred Share Purchase Rights”, together with the provisions of the Washington BCA described above under “Statutory Limitations on ‘Significant Business Transactions’’’, considered either individually or in the aggregate, may have an “anti-takeover” effect. These provisions could discourage a future takeover attempt which is not approved by Avista’s Board of Directors but which individual shareholders might deem to be in their best interests or in which shareholders would receive a premium for their shares over current market prices. As a result, shareholders who might desire to participate in such a transaction might not have an opportunity to do so.

 

The Rights described above under “Preferred Share Purchase Rights” would cause substantial dilution to a person or group that attempts to acquire Avista on terms not approved by the Board of Directors, except pursuant to an offer conditioned on a substantial number of Rights being acquired or redeemed. However, the Rights should not interfere with any merger or other business combination approved by the Board of Directors prior to the time that a person or group has acquired beneficial ownership of 10% or more of the Common Stock since until such time the Rights may be redeemed, or the Rights Agreement may be amended, as described above.

 

The provisions described above under “Classified Board of Directors” could also cause the removal of the incumbent Board of Directors or management to require more time or render such removal more difficult, procedurally or otherwise.

 

Liquidation Rights

 

In the event of any liquidation or dissolution of Avista, after satisfaction of the preferential liquidation rights of the Preferred Stock, the holders of Common Stock would be entitled to share ratably in all assets of Avista available for distribution to shareholders.

Pre-Emptive Rights

 

No holder of Common Stock has any pre-emptive rights.

 

Miscellaneous

 

The presently outstanding shares of Common Stock are fully paid and non-assessable. Upon issuance as contemplated by this prospectus and the applicable prospectus supplement, additional shares of Common Stock will be fully paid and nonassessable. The holders of such shares of Avista Common Stock are not and will not be subject to liability for further calls or assessment by, or for liabilities of, Avista.

 

The outstanding shares of Common Stock are listed on the New York Stock Exchange. Any new shares of Avista Common Stock will also be listed on that Exchange subject to official notice of issuance.

 

The Transfer Agent and Registrar for the Common Stock is The Bank of New York, 101 Barclay Street, 11^th Floor, New York, New York 10286.

 

Proposed Formation of Holding Company

 

General

 

Avista is in the process of reorganizing itself into a holding company structure. Pursuant to the Plan of Exchange between Avista and AVA, the Share Exchange would be effected whereby each outstanding share of Avista Common Stock (including any shares offered hereby) would be exchanged for one share of AVA Common Stock, so that the holders of Avista Common Stock would become holders of AVA Common Stock and Avista would become a subsidiary of AVA.

 

Immediately following the Share Exchange:

 

 

See “Avista Corporation — Proposed Formation of Holding Company” for additional general information regarding the proposed formation of a holding company.

 

Effective Time of Share Exchange; Conditions

 

The Share Exchange will become effective as of a date to be selected by Avista and AVA as provided in the Plan of Exchange, after satisfaction of the conditions set forth in the Plan of Exchange, including:

 

 

Notice of Effectiveness of Share Exchange

 

Promptly after the effective time of the Share Exchange, all shareholders of record of Avista Common Stock as of the date of the Share Exchange will be provided with notice that the Share Exchange has taken place.

Exchange of Stock Certificates Not Required

 

If the Share Exchange is consummated, the holders of Avista Common Stock will automatically become the owners of shares of AVA Common Stock on a share-for-share basis, and the present Common Stock certificates of Avista will automatically represent shares of AVA Common Stock. It will not be necessary for holders of Avista Common Stock to physically exchange their Common Stock certificates. After the effective time of the Share Exchange, as and when outstanding certificates of Avista Common Stock are presented for transfer, new certificates bearing AVA’s name will be issued. Holders of Avista Common Stock may surrender their old Avista Common Stock certificates in exchange for new AVA Common Stock certificates at any time.

 

Listing of AVA Common Stock

 

AVA intends to list AVA Common Stock on the New York Stock Exchange. AVA expects that before the effective time of the Share Exchange, the NYSE will authorize such listing “subject to official notice of issuance”. Such authorization is a condition to consummation of the Share Exchange. At the effective time, AVA will notify the NYSE that the Share Exchange has been consummated and this will complete the listing process. Thus, Avista shares will be listed on the NYSE until the effective time of the Share Exchange, and AVA shares will be listed at and after the effective time.

 

After the effective time of the Share Exchange, the Avista Common Stock will no longer be listed on any stock exchange because all shares of Avista Common Stock will be held by one shareholder, AVA.

 

Dividends

 

Dividends on AVA Common Stock

 

Following the effective time of the Share Exchange, AVA will not conduct directly any business operations from which it will derive any revenues. AVA plans to obtain funds for its operations from dividends paid to AVA on the stock of its subsidiaries and from sales of its securities, which may consist of debt securities and preferred stock, as well as additional shares of AVA Common Stock. Dividends on AVA Common Stock will depend primarily upon the results of operations, cash flows, and financial condition of Avista and AVA’s other subsidiaries, and their ability to pay dividends on their capital stock owned, directly or indirectly, by AVA.

 

The payment of dividends on AVA Common Stock is within the discretion of, and subject to declaration by, AVA’s Board of Directors. It is contemplated that AVA initially will pay dividends on AVA Common Stock at the current level of dividends paid on Avista Common Stock. In addition, it is contemplated that such dividends of AVA will be declared and paid on approximately the same schedule of dates now followed by Avista with respect to dividends on Avista Common Stock. The most recent dividend declared by the Board of Directors of Avista was $0.141/2 per share of Avista Common Stock, payable on December 15, 2006 to shareholders of record at the close of business on November 30, 2006.

 

Dividends on Avista Common Stock

 

Subject to the availability of earnings and the needs of its electric and gas utility business and to the rights of the holders of Avista preferred stock and further, to periodic review and declaration by its Board of Directors, Avista intends to make regular cash payments to AVA in the form of dividends on Avista Common Stock in amounts that, to the extent not otherwise provided by AVA’s other subsidiaries, would be sufficient for AVA to pay cash dividends on AVA Common Stock as referred to above, for operating expenses of AVA and for such other purposes as the Board of Directors of AVA may determine.

 

The declaration and payment of future dividends will be at the discretion of the Board of Directors of each of AVA, Avista and AVA’s other direct and indirect subsidiaries. There can be no assurance that payment of dividends will continue at current levels.

Other Information

 

Reference is made to the Proxy Statement-Prospectus, which is incorporated herein by reference, for additional information regarding the proposed formation of a holding company, including, without limitation, the federal income tax consequences of the Share Exchange.

 

Description of AVA Common Stock; Comparative Shareholder Rights

 

General

 

The authorized capital stock of AVA consists of 10,000,000 preferred shares, without nominal or par value, which is issuable in series (the “AVA Preferred Stock”), and 200,000,000 common shares (the “AVA Common Stock”). Avista has the same number of authorized shares of capital stock, of the same classes.

 

In the Share Exchange, AVA will issue a number of shares of AVA Common Stock equal to the number of shares of Avista Common Stock then outstanding. The terms of the AVA Common Stock include those stated in the AVA Articles and the AVA Bylaws (each as defined below) and those made applicable thereto by the Washington BCA. The following summary is not complete and is subject in all respects to the provisions of, and is qualified in its entirety by reference to, the AVA Articles, the AVA Bylaws and the Washington BCA. AVA’s Amended and Restated Articles of Incorporation and its Amended and Restated Bylaws, each substantially in the form to be in effect immediately prior to the effective time of the Share Exchange (the “AVA Articles” and the “AVA Bylaws”, respectively), are attached as Exhibits B and C, respectively, to the Proxy Statement — Prospectus, which is incorporated by reference. Whenever particular provisions of the AVA Articles or the AVA Bylaws are referred to, those provisions are incorporated as part of the statements made in this prospectus and those statements are qualified in their entirety by that reference.

 

Dividend Rights

 

After full provision for all AVA Preferred Stock dividends declared or in arrears, the holders of AVA Common Stock will be entitled to receive such dividends as may be lawfully declared from time to time by AVA’s Board of Directors.

 

The entitlement of the AVA Common Stock to dividends will be the same as that of the Avista Common Stock.

 

Voting Rights

 

The holders of the AVA Common Stock will have sole voting power, subject to any voting rights which may be granted to the holders of the AVA Preferred Stock or any series thereof and except as otherwise provided by law. Each holder of AVA Common Stock will be entitled to one vote per share, except that, in the election of directors, each holder will have “cumulative” voting rights by which such holder will be entitled to that number of votes which is equal to the number of directors to be elected multiplied by the number of shares held. These votes may all be cast for a single nominee for director or may be distributed among any two or more nominees.

 

The voting rights of the AVA Common Stock will be substantially the same as those of the Avista Common Stock.

 

Liquidation Rights

 

In the event of any liquidation or dissolution of AVA, after satisfaction of the preferential liquidation rights of the AVA Preferred Stock, the holders of AVA Common Stock would be entitled to share ratably in all assets of AVA available for distribution to shareholders.

 

The entitlement of the AVA Common Stock to assets upon liquidation or dissolution will be the same as that of the Avista Common Stock.

 

Pre-Emptive Rights

 

Like the holders of Avista Common Stock, holders of AVA Common Stock will have no pre-emptive rights.

Preferred Stock

 

The AVA Articles will provide that the Board of Directors may establish series of AVA Preferred Stock and, with respect to each series, determine the preferences, limitations, voting powers and relative rights thereof.

 

The Avista Board of Directors has similar authority with respect to Avista Preferred Stock, except that the Avista Articles contain limitations on permissible differences among series and provide that, except in the limited circumstances set forth in the Avista Articles and as provided by law, the holders of Avista Preferred Stock have no right to vote in the election of directors or for any other purpose.

 

Classified Board of Directors

 

Both the AVA Articles and the AVA Bylaws will provide for a Board of Directors divided into three classes. Each director of a class will generally serve for a term of three years, with only one class of directors being elected in each year. The classification of the Board of Directors reduces the impact of cumulative voting rights.

 

The Avista Articles and the Avista Bylaws contain substantially the same provisions for a classified Board of Directors.

 

Miscellaneous Corporate Governance Provisions

 

The AVA Articles will provide, as the Avista Articles currently provide, without any significant difference, that:

 

 

The AVA Bylaws will provide, as the Avista Bylaws currently provide, without any significant difference, that:

 

 

The AVA Articles will provide that the approval of two-thirds (2/3) of the outstanding shares of AVA Common Stock is required to alter, amend or repeal the provisions of the AVA Articles described above or the provision of the AVA Bylaws relating to procedures for the nomination of directors. The Avista Articles require an 80% shareholder vote for such matters.

Limitation of Liability; Indemnification

 

The AVA Articles will provide, as the Avista Articles currently provide, that:

 

 

Amendments to AVA Articles of Incorporation

 

The Washington BCA provides that, in the case of a public company, amendments to articles of incorporation must generally be approved by each voting group entitled to vote by the affirmative vote of the holders of a majority of all the votes entitled to be cast by that voting group, unless the articles of incorporation require a greater proportion.

 

As discussed under “Miscellaneous Corporate Governance Provisions”, the AVA Articles will provide that the affirmative vote of two thirds (2/3) of the outstanding shares of AVA Common Stock will be required to amend or repeal provisions of the AVA Articles relating to (a) calling special meetings of shareholders, (b) the number, tenure, vacancy, classification, nomination or removal of directors, or (c) adoption, amendment or repeal of the AVA Bylaws. All other amendments to the AVA Articles will be approved by the affirmative vote of a majority of the outstanding shares of AVA Common Stock and of any other voting group entitled to vote, unless a greater percentage is required by law.

 

The Avista Articles have provisions similar in substance, except that, as to all matters of the character described in the first sentence of the preceding paragraph, the Avista Articles require an affirmative vote of 80% of the outstanding shares of Avista Common Stock.

 

The Avista Articles have a provision similar in substance, except that, as to all matters of the character described in clause (c) of the preceding paragraph, the Avista Restated Articles require an 80% vote.

 

Amendments to Bylaws

 

The Washington BCA provides that the shareholders or the board of directors may amend, repeal or adopt bylaws unless the articles of incorporation reserve this power exclusively to the shareholders.

 

The AVA Articles and the AVA Bylaws provide that the Board of Directors has the power to adopt, amend or repeal the AVA Bylaws and that the shareholders may amend or repeal the AVA Bylaws or adopt new bylaws; provided, however, that the AVA Bylaws require the affirmative vote of at least two-thirds (2/3) of the outstanding shares of AVA Common Stock to alter, amend or repeal, or adopt any provision inconsistent with, provisions relating to the tenure, vacancy, classification or nomination of directors and calling and conduct of special meetings of shareholders.

 

The Avista Bylaws contain a proviso similar to that described above, except that the Avista Bylaws require an 80% vote.

 

Anti-Takeover Effect

 

The provisions of the AVA Articles and the AVA Bylaws described above under “Classified Board of Directors” and “Miscellaneous Corporate Governance Provisions”, together with the provisions of the Washington BCA described above under “Statutory Limitations on ‘Significant Business Transactions’,” considered either individually or in the aggregate, may have an “anti-takeover” effect. These provisions could discourage a future takeover attempt which is not approved by AVA’s Board of Directors but which individual shareholders might deem to be in their best interests or in which shareholders would receive a premium for their shares over current market prices. Certain of these provisions could also impede or delay the consideration of shareholder meetings of matters other than those the Board of Directors or officers deem appropriate or desirable. The provisions described above under “Classified Board of Directors” could also cause the removal of the incumbent Board of Directors or management to require more time or render such removal more difficult, procedurally or otherwise.

However, as discussed herein, substantially the same provisions are contained in the Avista Articles and the Avista Bylaws, except that, as noted under “Miscellaneous Corporate Governance Provisions”, where the AVA organizational documents will require a 662/3% shareholder vote to amend or repeal the provision in question, the Avista organizational documents currently require an 80% shareholder vote.

 

Moreover, as discussed below under “Certain Other Attributes of AVA Common Stock”, the Avista Articles contain a “fair price” provision which could discourage or impede a future takeover attempt. The AVA Articles will contain no such provision.

 

Like Avista Preferred Stock, AVA Preferred Stock will be issuable in series, and with terms, established by the AVA Board of Directors. Although the AVA Board of Directors has no current intention of doing so, it could authorize the issuance of one or more series having terms that could discourage or impede future takeover attempts.

 

Certain Other Attributes of AVA Common Stock

 

General

 

The Avista Articles contain certain provisions that the AVA Articles will not contain. In addition, as described below, Avista currently has a shareholder rights plan.

 

“Fair Price” Provision

 

The AVA Articles will not contain a “fair price” provision such as that contained in the Avista Articles, as described above.

 

Sales of Assets

 

The Washington BCA permits a corporation to sell, lease, exchange or otherwise dispose of all, or substantially all, of its property, other than in the usual and regular course of business if the transaction is recommended to the shareholders by the Board of Directors and approved by two-thirds (2/3) of all votes entitled to be cast, unless the articles of incorporation require a different proportion, which may not be less than a majority.

 

The Avista Articles provide that any property of Avista not essential to the conduct of its corporate business may be sold, leased, exchanged or otherwise disposed of, by authority of Avista’s Board of Directors. The Avista Articles further provide that Avista may sell, lease, exchange or otherwise dispose of all its property and franchises, or any of its property, franchises, corporate rights or privileges, essential to the conduct of its corporate business upon such terms as may be authorized by a majority of Avista’s directors and the holders of two-thirds (2/3) of the outstanding shares of Avista Common Stock (unless a greater percentage is required by law).

 

The AVA Articles will not include any provision relating to the sale, lease or other disposition of property or assets. AVA and Avista believe that the Washington BCA provides adequate protections to shareholders with respect to sales of assets.

 

Shareholder Rights Plan

 

AVA does not have a shareholder rights plan at the date of this prospectus. After the effective time of the Share Exchange, the Board of Directors of AVA may consider whether or not to adopt a shareholder rights plan.

The consolidated financial statements and management’s report on the effectiveness of internal control over financial reporting incorporated in this prospectus by reference from the Company’s Annual Report on Form 10-K have been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their reports (which reports (1) express an unqualified opinion on the financial statements and include an explanatory paragraph referring to certain changes in accounting and presentation resulting from the impact of recently adopted accounting standards, (2) express an unqualified opinion on management’s assessment regarding the effectiveness

of internal control over financial reporting, and (3) express an unqualified opinion on the effectiveness of internal control over financial reporting) which are incorporated herein by reference, and have been so incorporated in reliance upon the reports of such firm given upon their authority as experts in accounting and auditing.

 

With respect to the unaudited interim financial information, which is incorporated herein by reference, Deloitte & Touche LLP, an independent registered public accounting firm, have applied limited procedures in accordance with the standards of the Public Company Accounting Oversight Board (United States) for a review of such information. However, as stated in their reports included in the Company’s Quarterly Reports on Form 10-Q and incorporated by reference herein, they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their reports on such information should be restricted in light of the limited nature of the review procedures applied. Deloitte & Touche LLP are not subject to the liability provisions of Section 11 of the Securities Act of 1933 for their reports on the unaudited interim financial information because those reports are not “reports” or a “part” of the registration statement prepared or certified by an accountant within the meaning of Sections 7 and 11 of the Act.
