​ Impaired Loans (prior to the adoption of ASC 326) A loan is considered impaired when, based on then current information and events, it is probable that all contractual amounts due will not be collected in accordance with the terms of the loan. 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 or shortfalls generally are not classified as impaired. Management determines the significance of payment delays and shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. The Bank considers TDRs and all non-accrual loans, except non-accrual one-to-four family loans in less than the Federal National Mortgage Association (“FNMA”) Limits, to be impaired. Non-accrual one-to-four family loans equal to or less than the FNMA Limits, as well as all consumer loans, are considered homogeneous loan pools and are not required to be evaluated individually for impairment unless considered a TDR. Impairment is typically measured using the difference between the outstanding loan principal balance and either: 1) the likely realizable value of a note sale; 2) the fair value of the underlying collateral, net of likely disposal costs, if repayment is expected to come from liquidation of the collateral; or 3) the present value of estimated future cash flows (using the loan’s pre-modification rate for certain performing TDRs). If a TDR is substantially performing in accordance with its restructured terms, management will look to either the potential net liquidation proceeds of the underlying collateral or the present value of the expected cash flows from the debt service in measuring impairment (whichever is deemed most appropriate under the circumstances). If a TDR has re-defaulted, generally the likely realizable net proceeds from either a note sale or the liquidation of the collateral is considered when measuring impairment. Measured impairment is either charged off immediately or, in limited instances, recognized as an allocated reserve within the allowance for loan losses. The following tables summarize impaired loans with no related allowance recorded and with related allowance recorded as of the periods indicated (by collateral type within the real estate loan segment):

​ ​ Accruing Loans 90 Days or More Past Due: ​ The Company continued accruing interest on loans with an outstanding balance of $6.3 million at September 30, 2021, and loans with an outstanding balance of $3.3 million at December 31, 2020, all of which were 90 days or more past due on their respective contractual maturity dates. These loans continued to make monthly payments consistent with their initial contractual amortization schedule exclusive of the balloon payments due at maturity. These loans were well secured and/or were expected to be refinanced, and, therefore, remained on accrual status and were deemed performing assets at the dates indicated above. ​ Collateral Dependent Loans: ​ At September 30, 2021, the Company had collateral dependent loans which were individually evaluated to determine expected credit losses. ​ Collateral dependent CRE loans totaled $53.2 million and had a related allowance for credit losses totaling $7.6 million at September 30, 2021. The loans were secured by real estate. ​ Collateral dependent multi-family residential and residential mixed-use loans totaled $8.5 million and had a related allowance for credit losses totaling $0.6 million at September 30, 2021. The loans were secured by real estate. ​ Collateral dependent C&I loans totaled $4.4 million and had a related allowance for credit losses totaling $0.7 million at September 30, 2021. The loans were secured by business assets. ​ TDRs As of September 30, 2021, the Company had TDRs totaling $528 thousand. The Company has allocated $481 thousand of allowance for those loans at September 30, 2021, with no commitments to lend additional amounts. ​ During the nine months ended September 30, 2021, TDR modifications included reduction of outstanding principal, extensions of maturity dates, or favorable interest rates and loan terms than the prevailing market interest rates and loan terms. ​ During the three months ended September 30, 2021, the Company modified one CRE loan as a TDR, which subsequently paid off during the quarter. ​ The following table presents the loans by category modified as TDRs that occurred during the nine months ended September 30, 2021: ​

​ ​ There were no TDR charge-offs during the three and nine months ended September 30, 2021. TDRs did not have a material impact to the allowance for credit losses. There were no TDRs that subsequently defaulted. ​ ​ Loan payment deferrals due to COVID-19 Consistent with regulatory guidance to work with borrowers during the unprecedented situation caused by the COVID-19 pandemic and as outlined in the CARES Act, the Company established a formal payment deferral program in April 2020 for borrowers that have been adversely affected by the pandemic. ​ As of September 30, 2021, the Company had 17 loans, representing outstanding loan balances of $26.6 million, that were deferring full principal and interest (“P&I” deferrals). ​ The table below presents the P&I deferrals as of September 30, 2021: ​

Pursuant to guidance under Section 4013 of the CARES Act, a qualified loan modification, such as a payment deferral, is exempt from classification as a TDR as defined by GAAP. This applies if the loan was current as of December 31, 2019 and the modifications are related to arrangements that defer or delay the payment of principal or interest, or change the interest rate of the loan. This guidance was expected to expire on December 31, 2020. The 2021 Consolidated Appropriations Act, which was signed into law December of 2020, extended the exemption for TDR classification until the earlier of January 1, 2022 or the date that is 60 days after the date on which the national emergency concerning the COVID-19 outbreak is lifted. Risk-ratings on COVID-19 loan deferrals are evaluated on an ongoing basis. Credit Quality Indicators The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit structure, loan documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying them as to credit risk. This analysis includes all loans, such as multifamily residential, mixed-use residential (i.e., loans in which the aggregate rental income of the underlying collateral property is generated from both residential and commercial units, but 50% or more of such income is generated from the residential units), commercial real estate, mixed-use commercial real estate (i.e., loans in which the aggregate rental income of the underlying collateral property is generated from both residential and commercial units, but over 50% of such income is generated from the commercial units), ADC, C&I, as well as all one-to- four family residential and cooperative and condominium apartment loans. The Company uses the following definitions for risk ratings: ​ Special Mention. Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the Bank’s credit position at some future date. 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. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. ​ Doubtful. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of then existing facts, conditions, and values, highly questionable and improbable. All real estate and C&I loans not classified as Special Mention, Substandard, or Doubtful were deemed pass loans at both September 30, 2021 and December 31, 2020. For the three and nine months ended September 30, 2021, there were $11.9 million and $66.5 million of sales of criticized loans, respectively. For the three and nine months ended September 30, 2020, there were $3.0 million and $10.0 million of sales of criticized loans, respectively. ​ The following is a summary of the credit risk profile of loans by internally assigned grade as of the periods indicated, the years represent the year of origination for non-revolving loans: ​
