We perform an analysis of goodwill on an annual basis, and it is tested for impairment more frequently if events or changes in circumstances indicate that an asset might be impaired. We perform our annual analysis during our third quarter of each fiscal year, based on the goodwill amount as of the first business day of our third fiscal quarter. The result of the analysis indicated no goodwill impairment existed for our third quarter in fiscal 2018, which began on October 29, 2017.

In conducting our impairment testing, we compare the fair value of each of our business units to the related carrying value of the allocated assets. We utilize the income approach based on discounted projected cash flows to estimate the fair value of each unit. The projected cash flows use many estimates including market conditions, expected market demand and our ability to grow or maintain market share, gross profit, and expected expenditures for capital and operating expenses. Assets shared or not directly attributed to a reportable segment's activities are allocated to the reportable segment based on sales and other measures.
