Use of estimates

The preparation of our consolidated financial statements in conformity with GAAP requires management to make estimates, assumptions, and judgements that affect the reported amounts of assets and liabilities, and the disclosure of contingent assets and liabilities at the date of our consolidated financial statements, and the reported amount of revenues and expenses during the reporting period.

Significant estimates relied upon in preparing these consolidated financial statements include revenue recognition, accounts and notes receivable reserves, expected future cash flows used to evaluate the recoverability of long-lived assets, estimated fair values of long-lived assets used to record impairment charges related to goodwill, amortization periods, accrued expenses, and recoverability of the Company’s net deferred tax assets and any related valuation allowance.

Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results may differ from management’s estimates if past experience or other assumptions do not turn out to be substantially accurate.
