The requirements eliminate the current option to report other comprehensive income and its components in the Statement of Stockholders' Equity.

If, based on the qualitative assessment of events or circumstances, an entity determines it is not more likely than not that the goodwill fair value is less than its carrying amount, then it is not necessary to perform the two-step impairment test. However, if an entity concludes otherwise, then the two-step impairment test must be performed to identify potential impairment and to measure the amount of goodwill impairment, if any. We are currently evaluating the impact this guidance will have on our annual goodwill impairment testing for our 2013 fiscal year beginning August 1, 2012.
