We performed our annual impairment assessment in our third quarter of fiscal 2017 and 2016, and our analysis indicated that we had no impairment of goodwill. We evaluate goodwill for impairment annually during the fiscal third quarter and when an event occurs or circumstances change such that it is reasonably possible that impairment may exist. We account for goodwill and evaluate our goodwill balances and test them for impairment in accordance with related accounting standards.
