Product Warranties Disclosures [Abstract]

WARRANTY LIABILITY

WARRANTY LIABILITY

Telephonics offers warranties against product defects for periods generally ranging from one to two years, depending on the specific product and terms of the customer purchase agreement. Typical warranties require Telephonics to repair or replace the defective products during the warranty period at no cost to the customer. At the time revenue is recognized, Griffon records a liability for warranty costs, estimated based on historical experience, and periodically assesses its warranty obligations and adjusts the liability as necessary. AMES offers an express limited warranty for a period of ninety days on all products from the date of original purchase unless otherwise stated on the product or packaging.

Changes in Griffon’s warranty liability, included in Accrued liabilities, were as follows:
