Product Warranties

The Company generally warrants its products against certain manufacturing and other defects. These product warranties are provided for specific periods and/or usage of the product. The accrued product warranty costs are for a combination of specifically identified items and other incurred, but not identified, items based primarily on historical experience of actual warranty claims. This reserve is classified within other current liabilities.
