7. Goodwill

Goodwill is recorded by A&E. A fair value-based impairment test of the net book value of goodwill is performed annually or at an interim basis if certain events or circumstances indicate that an impairment loss may have occurred. The annual review was conducted in the first quarter of fiscal 2011, resulting in no goodwill impairment charge being required.
