Accounting Policies [Abstract]

Principles Of Consolidation

Principles of Consolidation

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

Operating Segments

Operating Segments

We operate as a single reportable segment. During the fiscal quarter ended December 30, 2016, we reorganized certain aspects of our internal business infrastructure primarily to integrate and align sales support more directly with our business units. Following the reorganization, we reassessed our business units and concluded that the composition of our reportable segments remains unchanged and that we continue to operate as a single reportable segment. This reflects the fact that our CODM, our Chief Executive Officer, continues to evaluate our financial information and resources, and continues to assess the performance of these resources, on a consolidated basis. All required financial segment information is therefore included in our unaudited interim condensed consolidated financial statements.

Use of Estimates

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 unaudited interim condensed consolidated financial statements and accompanying notes. Significant items subject to such estimates and assumptions include estimated selling prices for elements sold in ME revenue arrangements; valuation allowances for accounts receivable; carrying values of inventories and certain property, plant, and equipment, goodwill and intangible assets; fair values of investments; accrued liabilities including liabilities for unrecognized tax benefits, deferred income tax assets and liabilities, and stock-based compensation. Actual results could differ from our estimates.
