Use of Estimates
Use of Estimates
 
The preparation of financial statements in conformity with U.S. GAAP  requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Because these estimates and assumptions require significant judgment, actual results could differ from those estimates and could have a significant impact on our results of operations, financial position and cash flows.  We reevaluate our estimates and assumptions as needed, but at a minimum on a quarterly basis.  The most significant estimates include, but are not limited to, the allowance for doubtful accounts, inventory reserves, warranty accrual, worker's compensation accrual, medical insurance accrual, income taxes and share-based compensation.  Actual results could differ materially from those estimates.
