Aerojet Rocketdyne Holdings, Inc. Notes to Consolidated Financial Statements Note 1. Summary of Significant Accounting Policies a. Basis of Presentation and Nature of Operations b. Cash and Cash Equivalents c. Restricted Cash The consolidated financial statements of Aerojet Rocketdyne Holdings, Inc. ("Aerojet Rocketdyne Holdings" or the "Company") include the accounts of the Company and its 100% owned and majority owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain reclassifications have been made to financial information for prior years to conform to the current year’s presentation. The Company’s operations are organized into two segments: Aerospace and Defense —  includes the operations of the Company’s wholly-owned subsidiary Aerojet Rocketdyne, Inc. ("Aerojet Rocketdyne"), a leading technology-based designer, developer and manufacturer of aerospace and defense products and systems for the United States ("U.S.") government, including the Department of Defense ("DoD"), the National Aeronautics and Space Administration ("NASA"), and major aerospace and defense prime contractors. Real Estate —  includes the activities of the Company’s wholly-owned subsidiary Easton Development Company, LLC ("Easton") related to the re-zoning, entitlement, sale, and leasing of the Company’s excess real estate assets. The year of the Company's subsidiary, Aerojet Rocketdyne, ends on the last Saturday in December. The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires the Company to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. On December 20, 2020, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") with Lockheed Martin Corporation ("Lockheed Martin") and Mizar Sub, Inc., a wholly-owned subsidiary of Lockheed Martin ("Merger Sub"), pursuant to which, subject to the terms and conditions thereof, Merger Sub will merge with and into the Company (the "Merger") with the Company being the surviving corporation and a wholly-owned subsidiary of Lockheed Martin. Subject to the terms and conditions set forth in the Merger Agreement, each share of common stock outstanding as of immediately prior to the effective time of the Merger will be automatically converted into the right to receive cash in an amount equal to $56.00 per share, without interest, less, to the extent paid or payable as outlined below, the amount per share of the Pre-Closing Dividend (defined below). On December 19, 2020, the Company’s Board of Directors declared a one-time cash dividend of $5.00 per share (including shares underlying the 2.25% Convertible Senior Notes ("2¼% Notes") participating on an as-converted basis) (the "Pre-Closing Dividend"). The Pre-Closing Dividend is payable on March 24, 2021, to the holders of the Company’s shares and 2¼% Notes as of the close of business on March 10, 2021. The $56.00 per share price under the Merger Agreement is expected to be reduced to $51.00 after the payment of the Pre-Closing Dividend to the Company’s stockholders and holders of its 2¼% Notes participating on an as- converted basis (or, in the unlikely event that closing occurs after March 10, 2021, but before March 24, 2021, to the extent the Pre-Closing Dividend is payable after the closing). Closing of the Merger is anticipated to occur in the second half of 2021, subject to various customary conditions, including Company stockholder approval and regulatory approval under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. During 2020, the Company’s financial results and operations were not materially adversely impacted by the COVID-19 pandemic. As a defense industrial-base U.S. government contractor, the Company is considered an essential business by the U.S. and state governments and it continues to operate as such during the COVID-19 pandemic. The extent to which the Company’s future financial results could be impacted by COVID-19 pandemic depends on future developments that are highly uncertain and cannot be predicted at this time. The Company is not aware of any specific event or circumstance that would require an update to its estimates or judgments or a revision of the carrying value of its assets or liabilities as of the date of issuance of this Annual Report on Form 10-K. These estimates may change, as new events occur and additional information is obtained. Actual results could differ materially from these estimates under different assumptions or conditions. All highly liquid debt instruments purchased with a remaining maturity at the date of purchase of three months or less are considered to be cash equivalents. The Company aggregates its cash balances by bank, and reclassifies any negative balances, if applicable, to other current liabilities. As of December 31, 2020 and 2019, the Company designated $3.0 million as restricted cash to satisfy indemnification obligations for environmental remediation coverage.
