Reclassification

Certain amounts in the unaudited condensed consolidated financial statements and notes to the unaudited condensed consolidated financial statements for prior years have been reclassified to conform to the fiscal 2013 presentation. Net operating results have not been affected by these reclassifications.

The Company’s fiscal year is the 52- or 53-week period ending on the Saturday closest to January 31. In a 52-week year, each fiscal quarter consists of 13 weeks.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates, including those related to performance-based compensation, revenue recognition, provisions for sales returns and allowances, inventory excess and obsolescence, investment fair values, goodwill and other intangible assets, income taxes, litigation and other contingencies. In addition, the Company uses assumptions when employing the Monte Carlo simulation and Black-Scholes valuation models to calculate the fair value of share-based awards that are granted. When carrying values of certain assets and liabilities are not readily available from other sources, their carrying values are estimated based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from these estimates, and such differences could affect the results of operations reported in future periods.
