[1] The recorded investment in impaired loans consists of unpaid principal balance, net of charge-offs, interest payments received applied to principal and unamortized deferred loan origination fees and costs. For accruing impaired loans (TDRs for which management has concluded that the collectability of the loan is not in doubt), the recorded investment also includes accrued interest.
