Commitments and Contingencies Disclosure [Abstract]

In general, we warrant our products to be free from defects in material and workmanship under normal use and service. The warranty periods generally range from one to five years. We typically have the option to either repair or replace products we deem defective with regard to material or workmanship. Estimated warranty costs are accrued in the period that the related revenue is recognized based upon an estimated average per unit repair or replacement cost applied to the estimated number of units under warranty. These estimates are based upon historical warranty incidents and are evaluated on an ongoing basis to ensure the adequacy of the warranty accrual.

The following table summarizes the activity associated with the product warranty accrual (in thousands) and is included on our Condensed Consolidated Balance Sheets in Other Current Liabilities:
