In the first quarter of fiscal year 2016 and in fiscal year 2015, there were no significant changes in goodwill other than the impact of changes in foreign currency exchange rates, and an increase in goodwill from business acquisitions completed in those periods. For the periods ending August 31, 2015 and May 31, 2015, the Company had $160.0 million of accumulated impairment losses on goodwill.
