[1] The fair values of our deferred compensation plan investments are based on the closing market prices of the participants’ elected investments.
[2] The fair values of our interest rate swaps and interest rate caps are based upon Level 2 inputs which include valuation models as reported by our counterparties. The key inputs for the valuation models are quoted market prices, interest rates and forward yield curves. See Note 10 for details on the interest rate swaps and interest rate caps.
[3] As of December 25, 2013 and December 26, 2012, impaired assets related to underperforming restaurants were written down to their fair value. Impairment charges of $4.8 million and $0.7 million were recognized as a component of operating (gains), losses and other charges, net in our Consolidated Statements of Income for the years ended December 25, 2013 and December 26, 2012, respectively. To determine fair value, we used the income approach, which assumes that the future cash flows reflect current market expectations. These fair value measurements require significant judgment using Level 3 inputs, such as discounted cash flows from operations, which are not observable from the market, directly or indirectly.
