[1] Foreign currency derivative contracts are valued based on observable market spot and forward rates and classified within Level 2 of the fair value hierarchy. Interest rate swaps are valued based on observable market swap rates and classified within Level 2 of the fair value hierarchy. Cross-currency interest rate swaps are valued based on observable market spot and swap rates and classified within Level 2 of the fair value hierarchy. The total rate of return swap is valued based on observable market swap rates and the Company's credit spread, and is classified within Level 2 of the fair value hierarchy.

[2] The Company acquired Foodstar in China in Fiscal 2011. Consideration for this acquisition included a potential earn-out payment in Fiscal 2014 contingent upon certain net sales and EBITDA (earnings before interest, taxes, depreciation and amortization) targets during Fiscals 2013 and 2014. The fair value of the earn-out was estimated using a discounted cash flow model and is based on significant inputs not observed in the market and thus represents a Level 3 measurement. Key assumptions in determining the fair value of the earn-out include the discount rate, and revenue and EBITDA projections for Fiscals 2013 and 2014. As of October 28, 2012 there were no significant changes to the fair value of the earn-out recorded for Foodstar at the acquisition date. A change in fair value of the earn-out could have a material impact on the Company's earnings.
