Accrued Warranties

We provide product warranties for products sold through certain U.S. Government contract vehicles. We accrue a warranty liability at the time that we recognize revenue for the estimated costs that may be incurred in connection with providing warranty coverage. Warranties are valued using historical warranty usage trends; however, if actual product failure rates or service delivery costs differ from estimates, revisions to the estimated warranty liability may be required. Accrued warranties are reported as other current liabilities on the consolidated balance sheets.
