Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	1. BASIS OF PRESENTATION Globalstar, Inc. (“Globalstar” or the “Company”) provides Mobile Satellite Services (“MSS”) including voice and data communications and wholesale capacity services through its global satellite network. The Company’s only reportable segment is its MSS business. Thermo Companies, through commonly controlled affiliates, (collectively, “Thermo”) is the principal owner and largest stockholder of Globalstar. The Company’s Executive Chairman of the Board controls Thermo. The Company has prepared the accompanying unaudited interim condensed consolidated financial statements in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information. Certain information and footnote disclosures normally included in financial statements have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”); however, management believes the disclosures made are adequate to make the information presented not misleading. These financial statements and notes should be read in conjunction with the consolidated financial statements and notes thereto included in the Globalstar Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on March 1, 2023 (the “2022 Annual Report”). The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from estimates. The Company evaluates estimates on an ongoing basis. The Company has made certain reclassifications to prior period condensed consolidated financial statements to conform to current period presentation. These unaudited interim condensed consolidated financial statements include the accounts of Globalstar and all its subsidiaries. Intercompany transactions and balances have been eliminated in the consolidation. In the opinion of management, the information included herein includes all adjustments, consisting of normal recurring adjustments, that are necessary for a fair presentation of the Company’s condensed consolidated statements of operations, consolidated balance sheets, condensed consolidated statements of stockholders' equity and condensed consolidated statements of cash flows for the periods presented. The results of operations for the three and nine months ended September 30, 2023 are not necessarily indicative of the results that may be expected for the full year or any future period. Recently Issued Accounting Pronouncements In September 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") No. 2022-04: Liabilities — Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations. ASU 2022-04 added certain disclosure requirements for buyers in supplier finance programs. The amendments in the update require that buyers disclose qualitative and quantitative information about their supplier finance programs. Interim and annual requirements include disclosure of outstanding amounts under the obligations as of the end of the reporting period, and annual requirements include a rollforward of those obligations for the annual reporting period, as well as a description of payment and other key terms of the programs. This update is effective for annual periods beginning after December 15, 2022, and interim periods within those fiscal years, except for the requirement to disclose rollforward information, which is effective for fiscal years beginning after December 15, 2023. The Company adopted this standard when it became effective on January 1, 2023 and revised its disclosures pursuant to ASU 2022-04. Recently Adopted Accounting Pronouncements In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. ASU 2017-04 eliminates the requirement to calculate the implied fair value of goodwill, eliminating Step 2 from the goodwill impairment test. Under ASU 2017-04, goodwill impairment will be tested by comparing the fair value of a reporting unit with its carrying amount, and recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. ASU 2017-04 should be applied prospectively and is effective for annual and interim periods beginning after December 15, 2022, with early adoption permitted. Prior to August 2023, the Company did not have any recorded goodwill on its consolidated balance sheets. In connection with the License Agreement (discussed below) entered into in August 2023, the Company recorded goodwill and is now subject to the guidance pursuant to ASU 2017-04. The Company adopted ASU 2017-04 effective July 1, 2023. The adoption of the new standard did not have a material impact on the Company’s consolidated financial statements.
