Product Warranties
The Company’s products carry a limited warranty ranging from one to five years for the products within the IBW segment, and typically one year for products within the ISMS segment, and one to seven years for products within the CNS segment. The specific terms and conditions of those warranties vary depending upon the customer and the products sold. Factors that affect the estimate of the Company’s warranty reserve include: the number of units shipped, 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 are $228,000 and $229,000 as of September 30, 2016, and March 31, 2016, respectively, and are presented on the Condensed Consolidated Balance Sheets in Accrued expenses. The non-current portions of the warranty reserves are $232,000 and $207,000 as of September 30, 2016, and March 31, 2016, respectively, and are presented on the Condensed Consolidated Balance Sheets in Other non-current liabilities.
