Reclassifications Certain prior year amounts have been reclassified to conform with current year presentation. Use of Estimates The financial statements are prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). The accounting principles we use require us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and amounts of income and expenses during the reporting periods presented. These estimates include, among others, revenue recognition, trade promotions and sales incentives, valuation of accounts and chargeback receivables, accounting for acquisitions, valuation of long-lived assets, goodwill and intangible assets, stock-based compensation, and valuation allowances for deferred tax assets. We believe in the quality and reasonableness of our critical accounting estimates; however, materially different amounts may be reported under different conditions or using assumptions different from those that we have consistently applied.
