Because these estimates and assumptions require significant judgment, actual results could differ </span></div>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: revenue recognition, business combinations, the allowance for credit losses, inventory reserves, warranty accrual, workers compensation accrual, medical insurance accrual, share-based compensation, and income taxes. Actual results could differ materially from those estimates.
