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 2016, which was November 1, 2015. The result of the analysis indicated no goodwill impairment existed as of that date. During the fourth quarter of fiscal 2016, we performed an interim goodwill impairment analysis due to economic conditions causing slowing orders. The results of our analysis indicated no goodwill impairment was necessary. We are currently in the process of completing this annual analysis based on the goodwill amount as of the first business day of our third quarter of fiscal 2017.
