Organization, Consolidation and Presentation of Financial Statements [Abstract] |
BASIS OF PRESENTATION | BASIS OF PRESENTATION In the opinion of management, the accompanying unaudited, condensed consolidated financial statements contain all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the financial position of InterDigital, Inc. (individually and/or collectively with its subsidiaries referred to as “InterDigital,” the “Company,” “we,” “us” or “our,” unless otherwise indicated) as of September 30, 2025, the results of our operations for the three and nine months ended September 30, 2025 and 2024 and our cash flows for the nine months ended September 30, 2025 and 2024. The accompanying unaudited, condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and, accordingly, do not include all of the detailed schedules, information and notes necessary to state fairly the financial condition, results of operations and cash flows in conformity with United States generally accepted accounting principles (“GAAP”). The year-end condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by GAAP for year-end financial statements. Therefore, these financial statements should be read in conjunction with the financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (our “2024 Form 10-K”) as filed with the Securities and Exchange Commission (“SEC”) on February 6, 2025. Definitions of capitalized terms not defined herein appear within our 2024 Form 10-K. The results of operations for interim periods are not necessarily indicative of the results to be expected for the entire year. We have one reportable segment. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the financial statements, as well as the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates. Change in Accounting Policies There have been no material changes or updates to our existing accounting policies from the disclosures included in our 2024 Form 10-K, except as indicated below in "New Accounting Guidance". Reclassifications Certain reclassifications have been made to prior year amounts to conform to the current year presentation. Supplemental Cash Flow Information The following table presents additional supplemental cash flow information for the nine months ended September 30, 2025 and 2024 (in thousands):

New Accounting Guidance Accounting Standards Update: Improvements to Income Tax Disclosures In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Updates ("ASU") No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”. The amendments in the ASU enhance income tax disclosures, primarily through standardization, disaggregation of rate reconciliation categories, and income taxes paid by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption allowed. We adopted this guidance as of January 1, 2025, and we will include the necessary disclosures in our Annual Report on Form 10-K. The disclosures are required on an annual basis so there was no impact to this Quarterly Report on Form 10-Q. Accounting Standards Update: Disaggregation of Income Statement Expenses In November 2024, the FASB issued ASU No. 2024-03, "Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses". The amendments in the ASU require disclosures about specific types of expenses included in the expense captions presented on the Consolidated Statements of Income, as well as disclosures about selling expenses. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, with early adoption allowed. We are currently evaluating the impact of adoption on our financial disclosures. Accounting Standards Update: Induced Conversions of Convertible Debt Instruments In November 2024, the FASB issued ASU No. 2024-04, "Debt—Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments". The amendments in the ASU require disclosures for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion. ASU 2024-04 is effective for fiscal years beginning after December 15, 2025, with early adoption allowed. We are currently evaluating the impact of adoption on our consolidated financial statements. Accounting Standards Update: Targeted Improvements to the Accounting for Internal-Use Software In September 2025, the FASB issued ASU No. 2025-06, "Intangibles—Goodwill and Other Internal-Use Software (Subtopic 350-40)". The amendments in the ASU amends certain aspects of the accounting for and disclosure of software costs under ASC 350-40. ASU 2025-06 is effective for fiscal years beginning after December 15, 2027, with early adoption allowed. We are currently evaluating the impact of adoption on our consolidated financial statements.
