The most significant estimates made by management in the preparation of the financial statements relate to ultimate revenue and costs used for the amortization of investment in films and television programs; estimates of sales returns and other allowances and provisions for doubtful accounts; estimates related to the revenue recognition of sales or usage-based royalties; fair value of equity-based compensation; fair value of assets and liabilities for allocation of the purchase price of companies acquired; income taxes including the assessment of valuation allowances for deferred tax assets; accruals for contingent liabilities; and impairment assessments for investment in films and television programs, property and equipment, equity investments, goodwill and intangible assets. Actual results could differ from such estimates.</span></div>
