Warranty Reserves.

A reserve has been established to provide for the estimated future cost of warranties on a portion of the Company’s delivered products and is classified within accrued liabilities on the consolidated balance sheet. Management periodically reviews the reserves and makes adjustments accordingly. Warranties cover such factors as non-conformance to specifications and defects in material and workmanship. The following table shows changes in the warranty reserves since the end of fiscal 2012:
