HBP and CPP offer warranties against product defects for periods generally ranging from one to ten years, with limited lifetime warranties on certain door and fan models. Typical warranties require HBP and CPP 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. CPP 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 from the date of original purchase. Warranty costs expected to be incurred in the next 12 months are classified in accrued liabilities. Warranty costs expected to be incurred beyond one year are classified in other long-term liabilities. The current portion of warranty was $15,461 as of December 31, 2023 and $20,781 as of September 30, 2023. The long-term warranty liability was $1,239 at both December 31, 2023 and September 30, 2023.
