For consumer loans, these amounts represent TDR Loans for which we evaluate reserves using a discounted cash flow methodology. Each loan is individually identified as a TDR Loan and then grouped together with other TDR Loans with similar characteristics. The discounted cash flow analysis is then applied to these groups of TDR Loans. The loan balance above excludes TDR loans that are carried at the lower of amortized cost or fair value of the collateral less cost to sell which totaled $516 million and $303 million at September 30, 2012 and 2011, respectively.
