PRODUCT WARRANTIES

NOTE 11 - PRODUCT WARRANTIES

We generally provide a warranty for our products against defects over periods ranging from 12 to 24 months, depending upon the product. An accrual for estimated future costs relating to products returned under warranty is recorded as an expense when products are shipped. At the end of each fiscal quarter, we adjust our liability for warranty claims based on actual warranty claims experience as a percentage of revenues for the preceding one to two years, and we also consider the impact of known operational issues that may have a greater or lesser impact than historical trends. The warranty reserve is included in Other Current Liabilities in the consolidated balance sheets. Activity in the accrued warranty costs liability is as follows (in thousands):
