Goodwill is assessed for impairment by the Company annually or more frequently if events or circumstances change that would, more likely than not, reduce the fair value of the reporting until below its carrying value. The Company conducted its annual assessment for goodwill impairment in the fourth quarter of fiscal 2012 by applying a fair value-based test and determined that the fair value of the Company's reporting units exceeded their respective book values. In fiscal 2011 and 2010, the fair value of the Company's reporting units also exceeded their respective book values.
