Finally, he introduces the other Company witnesses who support this general rate case filing, which is duplicated below. Mr. Mark Thies, Executive Vice President, Chief Financial Officerand Treasurer, will provide a financial overview of Avista Corporation as well as explain our credit ratings and the Company's proposed capital structure and overall rate of return in this case. In brief, he provides information that shows: 1. Avista's plans call for a continuation of utility capital investments in generation, transmission, electric and natural gas distribution systems and technology to preserve and enhance service reliability for our customers, including the continued replacement of aging infrastucture. capital expenditures of approximately $405 million peryear (system) are planned for the five-yearperiod endingDecember 31,2024. Avista needs adequate cash flow from operations to fund these requirements, together with access to capital from external sources underreasonableterms, on a sustainable basis. 2. we are proposing an overall rate of return of 7.30 percent, which includes a 50 percent common equlty ratio, a 9.90percent return on equity, and a cost of debt of 4.70 percent. We believe our proposed overall rate of return of 7.30 percent and the proposed capital structure provide a reasonable balance between safety and economy. 3. Avista's corporate credit rating from stand ard & poor's (s&p) is currently BBB and Baa2 from Moody's Investors Service. Avista must operate a! a level that will support a solid investnent grade corporate credit rating in orderto access capital markets at reasonable rates. A supportive regulatory environment is an important consideration by the rating agencies when reviewingAvista. Maintainingsolid creditmetics and credit ratings will also help support a stock price necessary to issue equity under reasonable terms to fund capital requirements.

He concludesthat: To reflecttherisksandprospectsassociatedwithAvista'sjurisdictionalutility operations, his analyses focus on aproxy goup of l8 utilitieswith comparable invesftnent risks. Because investors' required return on equity is unobservable and no single method should be viewed in isolation, he appliesthe DCF, CAPM, ECAPM, and risk premium methods to estimate a fair ROE for Avista, as well as referencing the expmted earnings approach. Based on the results of these analyses and giving less weight to extremes at the high and low ends of the range, he concludes that the cost of equity for the proxy goup of utilities is in the 9.4 percent to 10.8 percent range, or 9.5 percent to 10.9 percent after incorporating an adjustment to account for tre impact of common equlty flotation costs. a a 1 ll T2 l3 t4 15 t6 l7 18 t9 20 2t 22 a o As reflected in the testimony of Mark T. Thies, Avista is requesting a fair ROE of 9.9 percent, wh ich is below the 1 0.2 percent midpo int of his recommended range. Considering capital market expectations, the exposures faced by Avista, and the economic requirements necessary to maintain financial integrity and support additional capital investment even under adverse circumstances, it is his opinion that 9.9 percent represents a reasonable ROE forAvista. 23 24 25 26 27 28 Mr. Rvan Krasselt, Vice President, Controller and Principal Accounting Officer, addresses the Company's application3 filed with the Idaho Public Utilities Commission ("Commission") on October 30,2020 (Case Nos.
