These concessions typically result from our loss mitigation activities and could include reductions in the interest rate, payment extensions, forbearance or other actions. TDRs are classified as non-performing at the time of restructuring and typically are returned to performing status after considering the borrower’s sustained repayment performance for a reasonable period of at least six When we modify loans in a TDR, we evaluate any possible impairment similar to other impaired loans based on the present value of expected future cash flows, discounted at the contractual interest rate of the original loan agreement, or use the current fair value of the collateral, less estimated selling costs, for collateral dependent loans. If we determine that the value of the modified loan is less than the recorded investment in the loan (net of previous charge-offs, deferred loan fees or costs and unamortized premium or discount), impairment is recognized through an allowance estimate or a charge-off to the allowance. In periods subsequent to modification, we evaluate all TDRs, including those that have payment defaults, for possible impairment and recognize impairment through the allowance.

The Company analyzes loans individually by classifying the loans as to credit risk. For commercial and non-residential real estate loans, the Company’s credit quality indicator is internally assigned risk ratings. Each commercial and non-residential real estate loan is assigned a risk rating upon origination. The risk rating is reviewed annually, at a minimum, and on an as needed basis depending on the specific circumstances of the loan. For residential real estate loans, multi-family, consumer direct and purchased auto loans, the Company’s credit quality indicator is performance determined by delinquency status. Delinquency status is updated regularly by the Company’s loan system for real estate loans, multi-family and consumer direct loans. The Company receives monthly reports on the delinquency status of the purchased auto loan portfolio from the servicing company. Generally, when residential real estate loans, multi-family and consumer direct loans become over 90 6 12 The Company uses the following definitions for risk ratings: ● Pass – loans classified as pass are of a higher quality and do not ● Special Mention – loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may ● Substandard – loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt.

Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance for Loan Losses . The allowance for loan losses is an amount necessary to absorb known or inherent losses that are both probable and reasonably estimable and is established through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not
