NOTE 1 — BASIS OF PRESENTATION

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and the instructions to Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation have been included. The accompanying unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements of Lam Research Corporation ("Lam Research" or the "Company") for the fiscal year ended June 26, 2011, which are included in the Annual Report on Form 10-K as of and for the year ended June 26, 2011 (the "2011 Form 10-K"). The Company's Forms 10-K, Forms 10-Q and Forms 8-K are available online at the Securities and Exchange Commission website on the Internet. The address of that site is www.sec.gov. The Company also posts its Forms 10-K, Forms 10-Q and Forms 8-K on its corporate website at http://investor.lamresearch.com.

The consolidated financial statements include the accounts of Lam Research Corporation and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. We use the equity method to account for equity investments in instances in which we own common stock or similar interests and have the ability to exercise significant influence, but not control, over the investee. The Company's reporting period is a 52/53-week fiscal year. The Company's current fiscal year will end June 24, 2012 and includes 52 weeks. The quarters ended December 25, 2011 (the "December 2011 quarter") and December 26, 2010 (the "December 2010 quarter") each included 13 weeks.

Certain amounts presented in the comparative financial statements for prior years have been reclassified to conform to the fiscal year 2012 presentation.
