During the fourth quarter of fiscal year 2015, we completed our annual testing for impairment of goodwill and, based on those tests, concluded that no impairment of goodwill existed as of October 31, 2015. During the quarter ending May 31, 2016, no triggering events have occurred that would indicate that it is more likely than not that the carrying values of any of our reporting units exceeded their fair values.
