[1] The fair values were developed using market observable data for all significant inputs.

[2] Wendy’s has provided loan guarantees to various lenders on behalf of franchisees entering into debt arrangements for new restaurant development and equipment financing. In addition during 2012, Wendy’s provided a guarantee to a lender for a franchisee in connection with the refinancing of the franchisee’s debt. We have accrued a liability for the fair value of these guarantees, the calculation of which was based upon a weighted average risk percentage established at inception adjusted for a history of defaults.

[3] The fair value of our indirect investment in Arby’s Restaurant Group, Inc. (“Arby’s”) is based on applying a multiple to Arby’s earnings before income taxes, depreciation and amortization per its current unaudited financial information. The carrying value of our indirect investment in Arby’s was reduced to zero during 2013 in connection with the receipt of a dividend. The fair values of our remaining investments are not significant and are based on our review of information provided by the investment managers or investees which was based on (1) valuations performed by the investment managers or investees, (2) quoted market or broker/dealer prices for similar investments and (3) quoted market or broker/dealer prices adjusted by the investment managers for legal or contractual restrictions, risk of nonperformance or lack of marketability, depending upon the underlying investments.

[4] The fair values were based on quoted market prices in markets that are not considered active markets.

[5] The fair values were determined by discounting the future scheduled principal payments using an interest rate assuming the same original issuance spread over a current U.S. Treasury bond yield for securities with similar durations.
