[2] The Company acquired Foodstar, a manufacturer of soy sauces and fermented bean curd 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 was based on significant inputs not observed in the market and thus represented a Level 3 measurement. Key assumptions in determining the fair value of the earn-out included the discount rate, and revenue and EBITDA projections for Fiscals 2013 and 2014. During the third quarter of Fiscal 2013, the Company renegotiated the terms of the earn-out agreement in order to give the Company additional flexibility in the future for growing its business in China, one of its largest and most important emerging markets. This renegotiation resulted in the settlement of the earn-out for a cash payment of $60.0 million, of which $15.5 million was reported in cash from operating activities and $44.5 million was reported in cash from financing activities on the consolidated cash flow statement for the nine months ended January 27, 2013. In addition, the Company incurred a $12.1 million charge in the third quarter ended January 27, 2013, which was recorded in SG&A on the consolidated income statement and in the Non-Operating segment, for the difference between the settlement amount and current carrying value of the earn-out as reported on the Company's balance sheet at the date of this transaction.
