Use of Estimates

Use of Estimates

We prepared our financial statements in conformity with GAAP, which requires us to make estimates and assumptions affecting the amounts reported in the financial statements and accompanying notes. Changes in these estimates and assumptions may have a material impact on our financial statements and accompanying notes. Examples of estimates and assumptions include valuing assets and liabilities acquired through business combinations, valuing and estimating useful lives of intangible assets, recognizing uncertain tax positions, estimating tax valuation allowances on tax attribute carryforwards, deferring certain revenues and costs, the determination of allowances for accounts receivable, estimating useful lives of property and equipment and estimating product warranties.
