Most of the Company’s products carry a limited warranty ranging up to seven years for Westell segment products and from one to three years for CNS segment products. The specific terms and conditions of those warranties vary depending upon the customer and the product sold. Factors that enter into the estimate of the Company’s warranty reserve include: the number of units shipped historically, anticipated rates of warranty claims, and cost per claim. The Company periodically assesses the adequacy of its recorded warranty liability and adjusts the reserve as necessary. The current portions of the warranty reserve were $131,000 and $110,000 as of June 30, 2012 and March 31, 2012, respectively, and are presented on the Condensed Consolidated Balance Sheets as Accrued expenses. The long-term portions of the warranty reserve were $90,000 and $133,000 as of June 30, 2012 and March 31, 2012, respectively, and are presented on the Condensed Consolidated Balance Sheets as Other long-term liabilities.
