Accrued Warranty Obligations

Unless otherwise stated in the Company’s product literature or in its agreements with customers, products sold by the Company’s Photonics and Optics Groups generally carry a one-year warranty from the original invoice date on all product materials and workmanship, other than filters and gratings products, which generally carry a 90-day warranty, and laser beam profilers and dental CAD/CAM scanners, which generally carry a two-year warranty. Products sold by the Photonics and Optics Groups to original equipment manufacturer (OEM) customers carry warranties generally ranging from 15 to 19 months. Products sold by the Company’s Lasers Group carry warranties that vary by product and product component, but generally range from 90 days to two years. In certain cases, such warranties for Lasers Group products are limited by either a set time period or a maximum amount of hourly usage of the product, whichever occurs first. Defective products will be either repaired or replaced, generally at the Company’s option, upon meeting certain criteria. The Company accrues a provision for the estimated costs that may be incurred for warranties relating to a product (based on historical experience) as a component of cost of sales. Short-term accrued warranty obligations, which expire within one year, are included in accrued expenses and other current liabilities and long-term warranty obligations are included in other long-term liabilities in the accompanying consolidated balance sheets.
