Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Goodwill During the third quarter of fiscal 2012, in furtherance of the Plan, we changed the structure of our internal organization and the way we manage our business. As a result, our reportable segment information has been restated to reflect the current structure (Note 16). Our evaluation of reporting units has also been reassessed and changed to reflect the current structure and operations. During the third quarter of fiscal 2012, we reassigned goodwill to the new reporting units and reportable segments based on the relative fair values of the reporting units. This resulted in goodwill of $225.9 million being assigned to our Core segment and $30.0 million being assigned to our non-Core segment. In connection with the reassignment of goodwill to our new reporting units, we determined an impairment triggering event occurred that required us to perform an interim goodwill impairment test. We performed the test for both our old and new reporting units to ensure no impairment existed prior to the reassignment of goodwill or resulted after the reassignment of goodwill. The tests indicated that our reporting units under our old and new structures had estimated fair values that were in excess of their carrying values, and thus, no impairment was present. We valued our reporting units for purposes of our goodwill impairment test and reassignment of our goodwill to the new reporting units using a market and income approach. However, a market approach was more heavily weighted to value the non-Core reporting unit given the current intentions to divest the non-Core product lines in furtherance of the Plan. The change in value of our goodwill since November 30, 2011 is the result of foreign currency translations, the finalization of purchase accounting measurement period adjustments (Note 7), goodwill transfered to assets held for sale (Note 6) and the immaterial errors identified as part of our income taxes payable analysis (Note 1).

Goodwill

During the third quarter of fiscal 2012, in furtherance of the Plan, we changed the structure of our internal organization and the way we manage our business. As a result, our reportable segment information has been restated to reflect the current structure (Note 16). Our evaluation of reporting units has also been reassessed and changed to reflect the current structure and operations. During the third quarter of fiscal 2012, we reassigned goodwill to the new reporting units and reportable segments based on the relative fair values of the reporting units. This resulted in goodwill of $225.9 million being assigned to our Core segment and $30.0 million being assigned to our non-Core segment.

In connection with the reassignment of goodwill to our new reporting units, we determined an impairment triggering event occurred that required us to perform an interim goodwill impairment test. We performed the test for both our old and new reporting units to ensure no impairment existed prior to the reassignment of goodwill or resulted after the reassignment of goodwill. The tests indicated that our reporting units under our old and new structures had estimated fair values that were in excess of their carrying values, and thus, no impairment was present.

We valued our reporting units for purposes of our goodwill impairment test and reassignment of our goodwill to the new reporting units using a market and income approach. However, a market approach was more heavily weighted to value the non-Core reporting unit given the current intentions to divest the non-Core product lines in furtherance of the Plan.

The change in value of our goodwill since November 30, 2011 is the result of foreign currency translations, the finalization of purchase accounting measurement period adjustments (Note 7), goodwill transfered to assets held for sale (Note 6) and the immaterial errors identified as part of our income taxes payable analysis (Note 1).
