[1] The fair values of the Company's long-term debt and other borrowing arrangements were estimated by calculating the net present value of future payments for each debt obligation or borrowing by: (i) using a risk-free rate applicable for an instrument with a life similar to the remaining life of each debt obligation or borrowing plus the current estimated credit risk spread for the Company or (ii) using the quoted market price at September 23, 2012 or December 25, 2011, as applicable.
