Such estimates include the useful lives and fair value of fixed assets, the fair value of investments, allowances for doubtful accounts and customer returns, inventory write-downs, potential reserves relating to litigation matters, accrued liabilities, and other reserves. The Company bases its estimates and judgments on its historical experience, knowledge of current conditions and its beliefs of what could occur in the future, given available information. Actual results may differ from those estimates, and such differences, may be material to the financial statements.
