Product Warranty Obligation/Commitments/Contingencies [Abstract]

8. PRODUCT WARRANTY OBLIGATION

In general, we warrant our products to be free from defects in material and workmanship under normal use and service. The warranty periods range from one to five years from the date of receipt. We have the option to 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 for the years ended September 30, 2011, 2010 and 2009 (in thousands):
