Goodwill is tested for impairment on an annual basis as of August 31, or whenever events or changes in circumstances indicate the carrying amount of goodwill exceeds its implied fair value. No events or changes in circumstances have occurred since the August 31, 2013 annual impairment test that would suggest it was more likely than not goodwill impairment existed.
