The Company tests goodwill for impairment at the reporting unit level annually during the fourth quarter of each fiscal year, or more frequently if events or circumstances indicate that the asset may be impaired. In the fourth quarter of fiscal 2018, the Company reviewed goodwill under the qualitative assessment of the authoritative guidance and concluded that it was more likely than not that the fair value of each reporting unit exceeded its carrying amount and that no indication of impairment existed.

There were no events or changes in circumstances which triggered an impairment review during the three and nine months ended March 30, 2019.
