In the opinion of management, all adjustments, consisting of only those of a normal recurring nature, considered necessary for a fair presentation of the financial position and interim results of Mattel, Inc. and its subsidiaries (“Mattel” or the “Company”) as of and for the periods presented, have been included. Because Mattel’s business is seasonal, results for interim periods are not necessarily indicative of those that may be expected for a full year. In preparing these financial statements, Mattel evaluated the events and transactions that occurred between September 30, 2009 through October 28, 2009, the date these financial statements were issued. The year-end balance sheet data was derived from audited financial statements, however, the accompanying interim notes to the consolidated financial statements do not include all disclosures required by accounting principles generally accepted in the United States of America. The financial information included herein should be read in conjunction with Mattel’s consolidated financial statements and related notes in its 2008 Annual Report on Form 10-K. On July 1, 2009, Mattel adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 105-10 (formerly Statement of Financial Accounting Standards (“SFAS”) No. 168, The FASB Accounting Standards Codification and Hierarchy of Generally Accepted Accounting Principles, a replacement of FASB Statement No. 162). ASC 105-10 establishes the FASB ASC as the source of authoritative accounting principles recognized by the FASB to be applied in preparation of financial statements in conformity with generally accepted accounting principles in the United States of America. The adoption of this standard had no impact on Mattel’s consolidated financial statements.   </div> 1.
