[1] There are no credit loss reserves associated with receivables classified as held for sale as they are carried at the lower of amortized cost or fair value.

[2] The TDR Loan balances included in the table above reflect the current carrying amount of TDR Loans and includes all basis adjustments on the loan, such as unearned income, unamortized deferred fees and costs on originated loans and premiums or discounts on purchased loans as well as any charge-off recorded in accordance with our existing charge-off policies. Additionally, the carrying amount of TDR Loans classified as held for sale has been reduced by both the lower of amortized cost or fair value adjustment as well as the credit loss reserves associated with these receivables prior to the transfer.
