[1] Recorded investment in a loan includes net deferred loan fees and costs, unamortized premium or discount, less any direct write-downs.

[2] TDRs involving changes in the amount or timing of principal payments may involve principal forgiveness or deferral of periodic and/or final principal payments. Because forgiveness of principal is rare for commercial loans, modifications typically have little to no impact on the loans’ projected cash flows and thus little to no impact on the allowance established for the loan. Charge-offs for amounts deemed uncollectable may be recorded at the time of the restructuring or may have already been recorded in prior periods such that no charge-off is required at the time of the modification.

[3] Average carrying value represents the average recorded investment balance and does not include related specific allowance.

[4] TDRs involving changes in the amount or timing of interest payments may involve a below-market interest rate.
