Product Warranty [Abstract]

Product Warranty

Note 4. Product Warranty

We provide a limited warranty for the replacement of defective products for a specified time period after sale. We estimate the costs that may be incurred under the limited warranty and record a liability in the amount of such anticipated costs at the time product revenue is recognized. Factors that affect our warranty liability include sales volumes along with historical and anticipated future rates of warranty claims.
