Principles of Consolidation

The consolidated financial statements include the accounts of Dolby Laboratories, Inc. and our wholly-owned and majority-owned subsidiaries. In addition, we have consolidated the financial results of jointly owned affiliated companies in which our principal stockholder or other entities have a noncontrolling interest. We report these noncontrolling interests as a separate line in our consolidated statements of operations as net income attributable to noncontrolling interest and in our consolidated balance sheets as a noncontrolling interest. We eliminate all intercompany accounts and transactions upon consolidation.

Use of Estimates

The preparation of our financial statements in accordance with U.S. GAAP requires management to make certain estimates and assumptions that affect the amounts reported and disclosed in our consolidated financial statements and accompanying notes.

Significant items subject to such estimates and assumptions include estimated shipments by our licensees for which we are owed a sales-based royalty. These estimates involve the use of historical data and judgment for several key attributes including industry estimates of expected shipments, the percentage of markets using our technologies, and average sale prices. Our estimates of royalty-based revenue also take into consideration the macroeconomic effect of global events that may impact our licensees' supply chain activities as well as demand for shipments.

Additional significant items subject to such estimates and assumptions include ESPs for performance obligations within revenue arrangements; allowance for credit losses for accounts receivable; carrying values of inventories and certain PP&E, goodwill and intangible assets; fair values of investments; accrued liabilities including unrecognized tax benefits, deferred income tax assets and liabilities, and contingent liabilities; and stock-based compensation. Actual results could differ from our estimates.

Fiscal Year

Our fiscal year is a 52 or 53 week period ending on the last Friday in September. The fiscal years presented herein include the 52 week period ended September 27, 2024 (fiscal 2024) and September 29, 2023 (fiscal 2023), and the 53 week period ended September 30, 2022 (fiscal 2022). Our fiscal year ending September 26, 2025 (fiscal 2025) will consist of 52 weeks.
