We review goodwill for impairment during the fourth quarter of each fiscal year or more frequently if events or circumstances indicate that an impairment loss may have occurred. In the fourth quarter of fiscal 2015, we completed the annual impairment test of goodwill, which indicated there was no goodwill impairment. During the six months ended December 26, 2015, there have been no events or circumstances that have required us to perform an interim assessment of goodwill for impairment.
