Product Warranties Disclosures [Abstract]

5. Warranty Reserves

The Company’s standard warranty obligation to its end-users provides for a period of one to two years from the date of shipment, while certain auto, aviation, and marine OEM products have a warranty period of two years or more from the date of installation. The Company’s estimates of costs to service its warranty obligations are based on historical experience and management’s expectations and judgments of future conditions, and are recorded as a liability on the balance sheet. The following reconciliation provides an illustration of changes in the aggregate warranty reserve.
