NOTE 10 - PRODUCT WARRANTIES

The Company generally warrants its products against defects over periods ranging from 3 to 24 months. 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 quarter, the Company adjusts its liability for warranty claims based on its actual warranty claims experience as a percentage of revenues for the preceding 12 to 24 months and also considers the impact of the known operational issues that may have a greater impact than historical trends. Accrued warranty costs are included in other current liabilities in the consolidated balance sheets. Activity in the accrued warranty costs liability for the nine months ended November 30, 2014 and 2013 is as follows (in thousands):
