Annual Return Rate
<1.0% Annual Return Rate (ARR) indicates the average against products shipped.
ARR includes all reasons for returns (failures, handling damage, NDF), but
does not include inventory credit returns.

Component Design Life
5 years (minimum) Component design life is defined as a.) the time period before identified
wear-out mechanisms impact the failure rate, or b.) the time period up to the
wear-out point when useful component life expires.
