Note 8. Product Warranties

Most of the Company's products carry a limited warranty ranging from one to three years for CNS products and up to seven years for OSP 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 $269,000 and $239,000 as of December 31, 2011 and March 31, 2011, respectively, and are presented on the Condensed Consolidated Balance Sheets as Accrued expenses. The long-term portions of the warranty reserve were $223,000 and $325,000 as of December 31, 2011 and March 31, 2011, respectively, and are presented on the Condensed Consolidated Balance Sheets in Other long-term liabilities. In addition, as of March 31, 2011 $194,000 of the warranty reserve was classified as held-for-sale. As a result of the CNS asset sale, this portion of the warranty liability was transferred to NETGEAR on April 15, 2011.
