Loans are placed on nonaccrual status when the full and timely collection of principal and interest is doubtful, generally when the loan becomes 90 days or more past due for principal or interest payment or if part of the principal balance has been charged off. When loans are placed on nonaccrual status, all interest previously accrued but not collected is reversed against current period interest income. All payments received on nonaccrual loans are accounted for using the cost recovery method. Under the cost recovery method, all cash collected is applied first to reduce the outstanding principal balance. A loan may be returned to accrual status if all delinquent principal and interest payments are brought current and the collectability of the remaining principal and interest payments in accordance with the loan agreement is reasonably assured. Loans whose repayments are insured by the Federal Housing Administration ("FHA") or guaranteed by the Department of Veterans' Affairs ("VA") are maintained on accrual status even if 90 days or more past due.</span></div>
