The majority of TDRs are included in the special mention, substandard or doubtful grading categories, which results in more elevated loss expectations when determining the expected cash flows that are used to determine the allowance for loan losses associated with these loans. When a restructured loan subsequently defaults, it is evaluated and downgraded if appropriate. The more severely graded the loan, the lower the estimated expected cash flows and the greater the allowance recorded. Further, TDRs over $500,000 and graded substandard or lower are evaluated individually for impairment through a review of collateral values. The following table shows the accrual status of non-PCI and PCI TDRs.
