Basis Of Presentation [Abstract]

Basis of Presentation

For financial reporting purposes, LSI Corporation (“LSI” or the “Company”) reports on a 13- or 14-week quarter with the year ending December 31. The first quarters of 2013 and 2012 consisted of 13 weeks each and ended on March 31, 2013 and April 1, 2012, respectively. The results of operations for the quarter ended March 31, 2013 are not necessarily indicative of the results to be expected for the full year.

The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ significantly from these estimates.

In management’s opinion, the accompanying unaudited condensed consolidated financial statements contain all normal recurring adjustments necessary for a fair statement of the Company’s financial position, results of operations, comprehensive income and cash flows for the interim periods presented. While the Company believes that the disclosures are adequate to make the information not misleading, these financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

Recent Accounting Pronouncements

Recent Accounting Pronouncement

In February 2013, the Financial Accounting Standards Board (“FASB”) issued additional guidance regarding the presentation of comprehensive income. The guidance requires an entity to present the effects on net income line items of significant amounts reclassified out of accumulated other comprehensive income, but only if the item reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. An entity shall provide this information either on the face of the financial statements or in the notes to the financial statements. The guidance is effective for fiscal years beginning after December 15, 2012. The Company adopted this guidance in the first quarter of 2013. The adoption did not impact the Company’s results of operations or financial position.
