Merchant Generating Assets (Generation & Marketing Segment) A project to reconstruct a defective dam structure at Racine began in the first quarter of 2017. In December 2017, and in accordance with the accounting guidance for impairments of long-lived assets, an impairment analysis was triggered by the expected costs of the dam reconstruction activities, resulting in the conclusion that the fair value of Racine, in its present condition, was $0 as of December 31, 2017. A pretax impairment charge equal to Racine’s net book value of $43 million was recognized in AEP’s 2017 statement of income. Construction activities at Racine continued throughout 2018, accumulating new capital expenditures of $35 million as of September 30, 2018. However, due to a significant increase in estimated costs to complete the reconstruction project, in the third quarter of 2018, an impairment analysis was performed. AEP performed step one of the impairment analysis using undiscounted cash flows for the estimated useful life of Racine based upon energy and capacity price curves, which were developed internally with observable Level 2 third party quotations and unobservable Level 3 inputs, as well as management’s forecasts of operating expenses and capital expenditures. AEP performed step two of the impairment analysis on Racine using a ten-year discounted cash flow model based upon similar forecasted information used in the step one test. The step two analysis resulted in a determination that the fair value of Racine, in its present condition, was $0 as of September 30, 2018. As a result, AEP recorded a pretax impairment of $35 million in Other Operation on the statement of income in the third quarter of 2018.
