Loans and Leases Receivable, Impaired, Description	A loan is considered impaired when it is probable that the Company will be unable to collect all amounts due (principal and interest) according to the contractual terms of the original loan agreement. Typically, factors used in determining if a loan is impaired include, but are not limited to, loans 90 days or more delinquent, loans internally designated as substandard or worse, on non-accrual status or trouble debt restructures (“TDRs”).
Financing Receivable, Modifications, Nature and Extent of Transaction	TDRs are loans where the Company, for economic or legal reasons related to the borrower's financial condition, has granted a concession to the borrower that it would otherwise not consider. A TDR typically involves a modification of terms such as a reduction of the stated interest rate or face amount of the loan, a reduction of accrued interest, or an extension of the maturity date(s) at a stated interest rate lower than the current market rate for a new loan with similar risk.
