Each bank is classified by whether the ratio of its allowance for loan and lease losses (ALLL) to nonperforming loans is greater than one. For each size category, the sum of all assets held by banks where this ratio is greater than one is divided by the sum all assets held by banks in the class. The allowance for loan and lease losses is the sum of Allowance for Loan and Lease Losses call item RCFD3123 and Allocated Transfer Risk Reserves call item RCFD3128. Total nonperforming loans equals the sum of Total Loans and Lease Finance Receivables, Nonaccrual call item RCFD1403 and Total Loans and Lease Financing Receivables, Past due 90 Days or More and Still Accruing call item RCFD1407.
