Warranties

The Company offers warranties for certain products that it manufactures, with the warranty term generally ranging from one to two years. Warranty reserves are established for costs expected to be incurred after the sale and delivery of products under warranty, based mainly on known product failures and historical experience. Actual repair costs incurred for products under warranty are charged against the established reserve balance as incurred. Changes in the warranty reserve for the three-month periods ended March 29, 2015, and March 30, 2014, are as follows:
