Termination of Proposed Acquisition by Hydro One | NOTE 25. TERMINATION OF PROP OSED ACQUISITION BY HYDRO ONE In July 2017, Avista Corp. entered into a Merger Agreement that provided for Avista Corp. to become an indirect, wholly-owned subsidiary of Hydro One, subject to the satisfaction or waiver of specified closing conditions, including approval by regulatory agencies. Termination of the Merger Agreement Due to the denial of the proposed merger by certain of the Company's regulatory commissions, in January 2019, Avista Corp., Hydro One and certain subsidiaries thereof, entered into a Termination Agreement indicating their mutual agreement to terminate the Merger Agreement. Pursuant to the terms of the Termination Agreement, Hydro One paid Avista Corp. a $103 million termination fee in January 2019. The termination fee was used for reimbursing the Company's transaction costs incurred from 2017 to 2019. The balance of the termination fee remaining after payment of 2019 transaction costs and applicable income taxes was used for general corporate purposes and reduced the Company's need for external financing. The 2019 costs were $19.7 million pre-tax and included financial advisers' fees, legal fees, consulting fees and employee time.
