General PacifiCorp, which includes PacifiCorp and its subsidiaries, is a United States regulated electric utility company serving retail customers, including residential, commercial, industrial, irrigation and other customers in portions of Utah, Oregon, Wyoming, Washington, Idaho and California. PacifiCorp owns, or has interests in, a number of thermal, hydroelectric, wind-powered and geothermal generating facilities, as well as electric transmission and distribution assets. PacifiCorp also buys and sells electricity on the wholesale market with other utilities, energy marketing companies, financial institutions and other market participants. PacifiCorp is subject to comprehensive state and federal regulation. PacifiCorp's subsidiaries support its electric utility operations by providing coal mining services. PacifiCorp is an indirect subsidiary of Berkshire Hathaway Energy Company (" BHE "), a holding company based in Des Moines, Iowa that owns subsidiaries principally engaged in energy businesses. BHE is a consolidated subsidiary of Berkshire Hathaway Inc. (" Berkshire Hathaway "). The unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and the United States Securities and Exchange Commission's rules and regulations for Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the disclosures required by GAAP for annual financial statements. Management believes the unaudited Consolidated Financial Statements contain all adjustments (consisting only of normal recurring adjustments) considered necessary for the fair presentation of the unaudited Consolidated Financial Statements as of September 30, 2020 and for the three- and nine-month periods ended September 30, 2020 and 2019 . The Consolidated Statements of Comprehensive Income have been omitted as net income materially equals comprehensive income for the three- and nine-month periods ended September 30, 2020 and 2019 . The results of operations for the three- and nine-month periods ended September 30, 2020 and 2019 are not necessarily indicative of the results to be expected for the full year. The preparation of the unaudited Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the unaudited Consolidated Financial Statements and the reported amounts of revenue and expenses during the period. Actual results may differ from the estimates used in preparing the unaudited Consolidated Financial Statements. Note 2 of Notes to Consolidated Financial Statements included in PacifiCorp's Annual Report on Form 10-K for the year ended December 31, 2019 describes the most significant accounting policies used in the preparation of the unaudited Consolidated Financial Statements. There have been no significant changes in PacifiCorp's assumptions regarding significant accounting estimates and policies during the nine-month period ended September 30, 2020 . Coronavirus Disease 2019 ("COVID-19") In March 2020, COVID-19 was declared a global pandemic and containment and mitigation measures were recommended worldwide, which has had an unprecedented impact on society in general and on economic conditions in the United States. COVID-19 has impacted many of PacifiCorp's customers ranging from high unemployment levels, an inability to pay bills and business closures or operating at reduced capacity levels. While COVID-19 has impacted PacifiCorp's financial results and operations through September 30, 2020, the impacts have not been material. However, more severe impacts may still occur that could adversely affect future financial results depending on the duration and extent of COVID-19. These impacts include, but are not limited to, lower operating revenue from reductions in the consumption of electricity by retail utility customers, particularly in the commercial and industrial customer classes, and higher bad debt expense resulting from a higher than average level of write-offs of uncollectible accounts associated with the suspension of disconnections across PacifiCorp's service territory and suspension of late payment fees in certain jurisdictions implemented to assist customers. While PacifiCorp does not currently expect a significant increase in employer contributions to its retirement plans, continued market volatility caused by COVID-19 may lead to increased contributions in the future. The duration and extent of COVID-19 and its future impact on PacifiCorp's business cannot be reasonably estimated at this time and the longer-term impacts of COVID-19 and related customer and governmental responses remain uncertain. Accordingly, significant estimates used in the preparation of PacifiCorp's unaudited Consolidated Financial Statements, including those associated with evaluations of certain long-lived assets for impairment, expected credit losses on amounts owed to PacifiCorp and potential regulatory deferral or recovery of certain costs may be subject to significant adjustments in future periods. In March and April 2020, PacifiCorp filed applications requesting authorization to defer costs associated with COVID-19 with the Utah Public Service Commission ("UPSC"), the Oregon Public Utility Commission ("OPUC"), the Wyoming Public Service Commission ("WPSC"), the Washington Utilities and Transportation Commission and the Idaho Public Utilities Commission ("IPUC"). In April 2020, as ordered by the California Public Utilities Commission, PacifiCorp filed to establish the COVID-19 Pandemic Protections Memorandum Account. The memorandum account was approved in September 2020, retroactive to March 4, 2020. In April 2020, the WPSC approved PacifiCorp's application to defer costs associated with COVID-19, subject to a public notice period, and required associated benefits arising from COVID-19 to be offset against the deferred costs. During the public notice period, one party to the proceeding filed a petition for a rehearing of the matter. In July, September and October 2020, the IPUC, the UPSC and the OPUC, respectively, approved PacifiCorp's applications to defer costs associated with COVID-19, requiring associated benefits arising from COVID-19 to be offset against the deferred costs.
