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 performed our annual analysis based on the goodwill amount as of the first business day of our third quarter in fiscal 2018, which was October 29, 2017. The result of the analysis indicated no goodwill impairment existed as of that date.
