[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 impaired accruing loans (troubled debt restructurings for which management has concluded that the collectibility of the loan is not in doubt), the recorded investment also includes accrued interest.

[2] Management may adjust appraisal values to reflect market value declines or other discounts resulting from its knowledge of the property.
