On June 4, 2020, Avista Corporation (Avista Corp. or the Company) entered into an amendment to its committed line of credit with the lenders identified therein, U.S. Bank National Association as an Issuing Bank, Wells Fargo Bank, National Association, as an Issuing Bank and MUFG Union Bank, N.A. as Administrative Agent and an Issuing Bank. The total amount of the committed line of credit remains unchanged from the original agreement at $400.0 million. The amendment to the committed line of credit extends the expiration date from April 18, 2021 to the new expiration date of April 18, 2022. The amendment also provides that the Company may request an extension of the committed line of credit for an additional one year beyond April 18, 2022, provided there is no event of default prior to the requested extension and the requested extension does not cause the remaining term until the expiration date to exceed five years. Any such extension is subject to the agreement of each lender, in its sole discretion. In addition to extending the expiration date, the amendment also adds a lower pricing level to the applicable interest rate. The committed line of credit is secured by a $400.0 million non-transferable First Mortgage Bond of the Company issued to MUFG Union Bank N.A, as Administrative Agent. Such First Mortgage Bond would only become due and payable in the event, and then only to the extent, that the Company defaults on its obligations under the committed line of credit. The customary covenants and default provisions from the original committed line of credit agreement, including a covenant not to permit the ratio of “consolidated total debt” to “consolidated total capitalization” of Avista Corp. to be greater than 65 percent at any time, remain unchanged from the original agreement.
