Acquisitions, Development and Divestitures | (PPL) On August 10, 2020, PPL announced that it initiated a formal process to sell its U.K. utility business. PPL noted that there can be no assurance of any specific outcome, including whether the sale process will result in the completion of any potential transaction, the timing or terms thereof, the value or benefits that may be realized or the effect that any potential transaction will have on future financial results. As a result of the potential sale, PPL assessed the recoverability of the assets of its U.K. utility business. PPL prepared probability-weighted undiscounted cash flow estimates as of December 31, 2020 and September 30, 2020 that considered the likelihood of the possible outcomes of the sale process, including the possibility of not selling the U.K. utility business. The resulting cash flow analyses exceeded the carrying value of the assets of the U.K. utility business. A change in the possible outcomes of the sale process could result in the carrying value of the assets of the U.K. utility business not being recoverable, which could result in an impairment in future periods. The U.K. utility business will continue to be classified as held and used until it meets the criteria to be classified as held for sale, which includes management obtaining a commitment to a plan to sell from its Board of Directors. Should the U.K. utility business meet the criteria to be classified as held for sale in a future period, PPL will be required at that time to compare the estimated fair value of its investment in the U.K. utility business, less costs to sell, to its carrying value, including accumulated other comprehensive losses related to the U.K. utility business, for impairment purposes. The resulting measurement may result in a loss. In addition, PPL will reassess its assertion of the indefinite reinvestment of the unremitted earnings of the U.K. utility business. See Note 21 for additional information on accumulated other comprehensive income and losses. See Note 6 for additional information on income taxes.
