We record estimated expense included in Cost of operations in the Condensed Consolidated Statements of Operations to satisfy contractual warranty requirements when we recognize the associated revenues on the related contracts, or in the case of a loss contract, the full amount of the estimated warranty costs is recognized when the contract becomes a loss contract. In addition, we record specific adjustments when we expect the actual warranty costs to significantly differ from the initial estimates. Factors that impact our estimate of warranty costs include prior history of warranty claims and our estimate of future costs of materials and labor. Such changes could have a material effect on our consolidated financial position, results of operations and cash flows.
