11. | Product Warranties
The Company’s warranty reserve is to cover the products sold and is principally at our Effox, Met-Pro and Aarding subsidiaries. The warranty accrual is based on historical claims information. The warranty reserve is reviewed and adjusted as necessary on a quarterly basis. Warranty accrual is not significant at the Company’s other operations due to the nature of the work which includes installation and testing. Accrued warranty expense is included in “Accounts payable and accrued expenses” on our condensed consolidated balance sheets, and the change in accrued warranty expense is summarized in the following table:
