Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Concentration of Credit Risk Our financial instruments that are exposed to concentrations of credit risk principally consist of cash, cash equivalents, restricted cash, investments, accounts receivable, and contract assets. We maintain cash, cash equivalents, and investments with multiple financial institutions that have high credit standing, and that we believe are financially sound and have minimal credit risk exposure, although at times our balances may exceed the applicable insurance coverage limits. We monitor and manage the overall counterparty credit risk exposure of our cash balances to individual financial institutions on an ongoing basis. Our investment portfolio may consist of investment-grade securities diversified amongst security types, industries, and issuers. All of our securities are held in custody by large national financial institutions. Our investment policy limits the amount of credit exposure to a maximum of 5% of our total portfolio to any one issuer, except for the U.S. Treasury, and we believe no significant concentration risk exists with respect to these investments. We also mitigate counterparty risk through entering into derivative contracts with high-credit-quality financial institutions. Actual or potential defaults of one or more financial institutions could impact our results of operations or financial position, and make it challenging to find alternative qualified counterparties. The majority of our licensing revenue is generated from customers outside of the United States ("U.S."). We manage the credit risk posed by non-U.S. customers by performing regular evaluations of the creditworthiness of our licensing customers and recognize revenue in accordance with U.S. GAAP. Recently Issued Accounting Standards Standards Not Yet Effective Income Taxes. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires further enhancement of income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. This ASU will be effective for our annual period beginning September 27, 2025, and requires prospective application with the option to apply the standard retrospectively. We will begin including the enhanced income tax disclosures on a prospective basis within the Form 10-K for the year ended September 25, 2026, but do not expect the standard’s adoption to have a material impact on the consolidated financial statements. Income Statement. In November 2024, the FASB issued ASU 2024-03, Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires public companies to disclose, in interim and annual reporting periods, additional information about certain expenses in notes to financial statements, including purchases of inventory, employee compensation, depreciation, amortization of intangible assets, and selling expenses. In January 2025, the FASB issued ASU 2025-01, Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date, which clarified the effective date of ASU 2024-03. This standard will be effective for Dolby's annual period beginning September 25, 2027 and interim periods beginning September 30, 2028, with early adoption permitted. We are currently in the process of evaluating the impact of the standard's adoption on our consolidated financial statements and related disclosures. Intangibles. In September 2025, the FASB issued ASU 2025-06, Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which eliminates references to the previous stage-based model, and requires capitalization of software costs when management has committed to the software project and it is probable the software will be completed and perform its intended use. This standard is effective for Dolby beginning September 30, 2028, and may be applied prospectively, retrospectively, or using a modified transition approach, with early adoption permitted. We are currently in the process of evaluating the impact of the standard's adoption on our consolidated financial statements and related disclosures. Environmental Credits and Environmental Credit Obligations. In May 2026, the FASB issued ASU 2026-02, Environmental Credits and Environmental Credit Obligations (Topic 818), which establishes guidance for the recognition, measurement, presentation, and disclosure of environmental credits and environmental credit obligations. This standard will be effective for Dolby's annual period beginning September 30, 2028, including interim periods within that annual period, and required to be adopted retrospectively through a cumulative-effect adjustment to the opening balance of retained earnings as of the beginning of the annual reporting period of adoption, with early adoption permitted. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements.
