Asset Fair Market Value Adjustments Charged To Earnings

During fiscal 2012 and 2011, we recognized fair market value adjustments with a charge to earnings for these assets as follows:

	Year Ended September 30, 2012
	Carrying Value before adjustment		Fair value adjustment			Carrying value after adjustment
Property, plant and equipment (1)	$	21.5	$	(14.4	)	$	7.1

	Year Ended October 2, 2011
	Carrying Value before adjustment		Fair value adjustment			Carrying value after adjustment
Property, plant, and equipment (1)	$	8.8	$	(5.9	)	$	2.9
Other assets (2)	$	22.1	$	(22.1	)	$	—

(1) These assets primarily consist of leasehold improvements in underperforming stores. The fair value was determined using a discounted cash flow model based on expected future store revenues and operating costs, using internal projections. The resulting impairment charge was included in store operating expenses.

(2) The fair value was determined using valuation techniques, including discounted cash flows, comparable transactions, and/or comparable company analyses. The resulting impairment charge was included in other operating expenses.
