Accrued expenses	$	81,060	$	65,494

Settlement obligations included in the table above relate to claims involving the Company’s products that may have caused a failure in the customer’s product. Although the Company does not agree with the claim, as its product met the customer’s specifications, the Company considered a number of factors and decided not to dispute the claim but make certain in-kind payments as demanded by the customer. These settlement obligations are accrued when they are deemed probable and can be reasonably estimated.
