Recent Accounting Pronouncements	Recent Accounting Pronouncements Allowance for Credit Losses – The Company adopted ASU No. 2016-13 on January 1, 2021 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures. ASU 2016-13 was effective for the Company as of January 1, 2020. Under Section 4014 of the CARES Act, financial institutions required to adopt ASU 2016-13 as of January 1, 2020 were provided an option to delay the adoption of the Current Expected Credit Loss (“CECL” or the “CECL Standard”) framework. The Company elected to defer adoption of the CECL Standard until January 1, 2021. The CECL Standard requires that the measurement of all expected credit losses for financial assets held at the reporting date be based on historical experience, current conditions, and reasonable and supportable forecasts. This standard requires financial institutions and other organizations to use forward-looking information to better inform their credit loss estimates. Results for reporting periods beginning after January 1, 2021 are presented under the CECL Standard while prior period amounts will continue to be reported in accordance with previously applicable GAAP. The adoption of the CECL standard resulted in an initial decrease of $3.9 million to the allowance for credit losses and an increase of $1.4 million to the reserve for unfunded commitments in other liabilities. The after-tax cumulative-effect adjustment of $1.7 million was recorded in retained earnings as of January 1, 2021. The allowance for credit losses is a valuation allowance that is deducted from the amortized cost basis of loans to present the net amount expected to be collected on the loans. Loan losses are charged against the allowance when management believes it has confirmed the loan balance is uncollectible. Subsequent recoveries, if any, are credited to the allowance. The CECL Standard, which requires that debt securities held to maturity be accounted for under the current expected credit losses model, including historical loss experience and impact of current conditions and reasonable and supportable forecasts, with an associated allowance for credit losses. In addition, while credit losses on debt securities available for sale should be measured in accordance with the other-than-temporary impairment (“OTTI”) framework under current GAAP, the amendments in the CECL Standard require that these credit losses be presented as an allowance for credit losses. For AFS debt securities, a decline in fair value due to credit loss results in recording an allowance for credit losses to the extent the fair value is less than the amortized cost basis. Management estimates the allowance balance required using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historically observed credit loss experience of peer banks within our geography provide the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level, or terms as well as changes in environmental conditions, such as changes in unemployment rates, gross domestic product, and real estate pricing. Management evaluates the adequacy of the allowance on a quarterly basis. The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist. The Company has identified the following portfolio segments and measures the allowance for credit losses using the following methods: One-to-four family residential, including condominium and cooperative apartment loans - Loans in this classification consist of residential real estate and one-to-four family real estate properties, and may have a mixed-use commercial aspect. Owner-occupied properties are generally underwritten based upon an appraisal performed by an independent, state licensed appraiser and the credit quality of the individual borrower. Investment properties require: (1) a maximum loan-to-value ratio of 75% based upon an appraisal performed by an independent, state licensed appraiser, and (2) sufficient rental income from the underlying property to adequately service the debt, represented by a minimum debt service ratio of 1.25x. The credit quality of this portfolio is largely dependent on economic factors, such as unemployment rates and housing prices. Multifamily residential and residential mixed-use loans - Loans in this classification consist of multifamily residential real estate with a minimum of five residential units, and may have a mixed-use commercial aspect of less than 50% of the property’s rental income. The Bank’s underwriting standards for multifamily residential loans generally require: (1) a maximum loan-to-value ratio of 75% based upon an appraisal performed by an independent, state licensed appraiser, and (2) sufficient rental income from the underlying property to adequately service the debt, represented by a minimum debt service ratio of 1.20x. Repayment of multifamily residential loans is dependent, in significant part, on cash flow from the collateral property sufficient to satisfy operating expenses and debt service. Future increases in interest rates, increases in vacancy rates on multifamily residential or commercial buildings, and other economic events, such as unemployment rates, which are outside the control of the borrower or the Bank could negatively impact the future net operating income of such properties. Similarly, government regulations, such as the existing New York City Rent Regulation and Rent Stabilization laws, could limit future increases in the revenue from these buildings. Commercial real estate and commercial mixed-use loans - Loans in this classification consist of commercial real estate, both owner-occupied and non-owner occupied, and may have a residential aspect of less than 50% of the property’s rental income. The Bank’s underwriting standards for commercial real estate loans generally require: (1) a maximum loan-to-value ratio of 75% based upon an appraisal performed by an independent, state licensed appraiser, and (2) sufficient rental income from the underlying property to adequately service the debt, represented by a minimum debt service ratio of 1.25x. Included in commercial real estate loans are also certain Small Business Administration ("SBA") loans in which the loan is secured by underlying real estate as collateral. The Bank may sell a portion of the loan, guaranteed by the SBA, to a third-party investor. Repayment of commercial real estate loans is often dependent upon successful operation or management of the collateral properties, as well as the success of the business and retail tenants occupying the properties. Repayment of such loans is generally more vulnerable to weak economic conditions, such as unemployment rates and commercial real estate prices. Acquisition, development, and construction loans - Loans in this classification consist of loans to purchase land intended for further development, including single-family homes, multi-family housing, and commercial income properties. In general, the maximum loan-to-value ratio for a land acquisition loan is 50% of the appraised value of the property. The credit quality of this portfolio is largely dependent on economic factors, such as unemployment rates and commercial real estate prices. Commercial, Industrial and Agricultural Loans - Loans in this classification consist of lines of credit, revolving lines of credit, and term loans, generally to businesses or high net worth individuals. The owners of these businesses typically provide recourse such that they guarantee the debt. The lines of credit are generally secured by the assets of the business, though they may at times be issued on an unsecured basis. Generally speaking, they are subject to renewal on an annual basis based upon review of the borrower’s financial statements. Term loans are generally secured by either specific or general asset liens of the borrower’s business. These loans are granted based upon the strength of the cash generation ability of the borrower. Included in C&I loans are also certain SBA loans in which the loan is secured by underlying assets of the business (excludes SBA Paycheck Protection Program loans from allowance for credit losses as these loans carry a 100% guarantee from the SBA). The Bank may sell a portion of the loan, guaranteed by the SBA, to a third-party investor. The credit quality of this portfolio is largely dependent on economic factors, such as unemployment rates. Other Loans – Loans in this classification consist of installment and consumer loans. Repayment is dependent on the credit quality of the individual borrower. The credit quality of this portfolio is largely dependent on economic factors, such as unemployment rates and housing prices. Loans that do not share risk characteristics are evaluated on an individual basis based on various factors. Loans evaluated individually are not included in the collective evaluation. Factors that may be considered are borrower delinquency trends and nonaccrual status, probability of foreclosure or note sale, changes in the borrower’s circumstances or cash collections, borrower’s industry, or other facts and circumstances of the loan or collateral. Individually Evaluated Loans with an ACL and Other Real Estate Owned: For collateral-dependent loans where the Company has determined that foreclosure of the collateral is probable, or where the borrower is experiencing financial difficulty and the Company expects repayment of the loan to be provided substantially through the operation or sale of the collateral, the ACL is measured based on the difference between the fair value of the collateral, less the estimated costs to sell, and the amortized cost basis of the loan as of the measurement date. The fair value of real estate collateral is determined based on recent appraised values. The fair value of other real estate owned is also determined based on recent appraised values less the estimated cost to sell. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Adjustments may relate to location, square footage, condition, amenities, market rate of leases as well as timing of comparable sales. All appraisals undergo a second review process to ensure that the methodology employed and the values derived are reasonable. The fair value of non-real estate collateral, which includes inventory, may be determined based on an appraisal, net book value per the borrower’s financial statements, aging reports, or by reference to market activity, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation and management’s expertise and knowledge of the borrower and its business. For non-collateral-dependent loans, ACL is measured based on the difference between the present value of expected cash flows and the amortized cost basis of the loan as of the measurement date. Appraisals for collateral-dependent loans are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by the Company. Once received, the Appraisal and Credit Departments review the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. Management also considers the appraisal values for commercial properties associated with current loan origination activity. Collectively, this information is reviewed to help assess current trends in commercial property values. For each collateral dependent loan, management considers information that relates to the type of property to determine if such properties may have appreciated or depreciated in value since the date of the most recent appraisal. Adjustments to fair value are made only when the analysis indicates a probable decline in collateral values. Adjustments made in the appraisal process are not deemed material to the overall consolidated financial statements given the level of collateral dependent loans measured at fair value on a non-recurring basis. Allowance for Credit Losses on Off-Balance Sheet Credit Exposures – The Company estimates expected credit losses over the contractual period in which the Company is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. The allowance for credit losses on off-balance sheet credit exposures, which is included in other liabilities on the consolidated statements of financial condition, is adjusted as a provision for credit loss expense in other operating expense. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life, which is the same as the expected loss factor as determined based on the corresponding portfolio segment. Loans acquired in a business combination – The Company adopted ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, on January 1, 2021 which now requires the Company to record purchased financial assets with credit deterioration (PCD assets), defined as a more-than-insignificant deterioration in credit quality since origination or issuance, at the purchase price plus the allowance for credit losses expected at the time of acquisition. Under this method, there is no credit loss expense affecting net income on acquisition of PCD assets. Changes in estimates of expected losses after acquisition are recognized as credit loss expense (or reversal of credit loss expense) in subsequent periods as they arise. Any non-credit discount or premium resulting from acquiring a pool of purchased financial assets with credit deterioration shall be allocated to each individual asset. At the acquisition date, the initial allowance for credit losses determined on a collective basis shall be allocated to individual assets to appropriately allocate any non-credit discount or premium. The non-credit discount or premium, after the adjustment for the allowance for credit losses, shall be accreted to interest income using the interest method based on the effective interest rate determined after the adjustment for credit losses at the adoption date. A purchased financial asset that does not qualify as a PCD asset is accounted for similar to an originated financial asset. Generally, this means that an entity recognizes the allowance for credit losses for non-PCD assets through net income at the time of acquisition. In addition, both the credit discount and non-credit discount or premium resulting from acquiring a pool of purchased financial assets that do not qualify as PCD assets shall be allocated to each individual asset. This combined discount or premium shall be accreted to interest income using the effective yield method.

Recent Accounting Pronouncements

Allowance for Credit Losses – The Company adopted ASU No. 2016-13 on January 1, 2021 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures. ASU 2016-13 was effective for the Company as of January 1, 2020.

This standard requires financial institutions and other organizations to use forward-looking information to better inform their credit loss estimates. Results for reporting periods beginning after January 1, 2021 are presented under the CECL Standard while prior period amounts will continue to be reported in accordance with previously applicable GAAP.

The adoption of the CECL standard resulted in an initial decrease of $3.9 million to the allowance for credit losses and an increase of $1.4 million to the reserve for unfunded commitments in other liabilities.

Management evaluates the adequacy of the allowance on a quarterly basis.

The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist. The Company has identified the following portfolio segments and measures the allowance for credit losses using the following methods:

One-to-four family residential, including condominium and cooperative apartment loans - Loans in this classification consist of residential real estate and one-to-four family real estate properties, and may have a mixed-use commercial aspect. Owner-occupied properties are generally underwritten based upon an appraisal performed by an independent, state licensed appraiser and the credit quality of the individual borrower. Investment properties require: (1) a maximum loan-to-value ratio of 75% based upon an appraisal performed by an independent, state licensed appraiser, and (2) sufficient rental income from the underlying property to adequately service the debt, represented by a minimum debt service ratio of 1.25x. The credit quality of this portfolio is largely dependent on economic factors, such as unemployment rates and housing prices.

Multifamily residential and residential mixed-use loans - Loans in this classification consist of multifamily residential real estate with a minimum of five residential units, and may have a mixed-use commercial aspect of less than 50% of the property’s rental income. The Bank’s underwriting standards for multifamily residential loans generally require: (1) a maximum loan-to-value ratio of 75% based upon an appraisal performed by an independent, state licensed appraiser, and (2) sufficient rental income from the underlying property to adequately service the debt, represented by a minimum debt service ratio of 1.20x. Repayment of multifamily residential loans is dependent, in significant part, on cash flow from the collateral property sufficient to satisfy operating expenses and debt service. Future increases in interest rates, increases in vacancy rates on multifamily residential or commercial buildings, and other economic events, such as unemployment rates, which are outside the control of the borrower or the Bank could negatively impact the future net operating income of such properties. Similarly, government regulations, such as the existing New York City Rent Regulation and Rent Stabilization laws, could limit future increases in the revenue from these buildings.

Commercial real estate and commercial mixed-use loans - Loans in this classification consist of commercial real estate, both owner-occupied and non-owner occupied, and may have a residential aspect of less than 50% of the property’s rental income. The Bank’s underwriting standards for commercial real estate loans generally require: (1) a maximum loan-to-value ratio of 75% based upon an appraisal performed by an independent, state licensed appraiser, and (2) sufficient rental income from the underlying property to adequately service the debt, represented by a minimum debt service ratio of

1.25x. Included in commercial real estate loans are also certain Small Business Administration ("SBA") loans in which the loan is secured by underlying real estate as collateral. The Bank may sell a portion of the loan, guaranteed by the SBA, to a third-party investor. Repayment of commercial real estate loans is often dependent upon successful operation or management of the collateral properties, as well as the success of the business and retail tenants occupying the properties.

The Bank may sell a portion of the loan, guaranteed by the SBA, to a third-party investor. The credit quality of this portfolio is largely dependent on economic factors, such as unemployment rates.

Other Loans – Loans in this classification consist of installment and consumer loans. Repayment is dependent on the credit quality of the individual borrower. The credit quality of this portfolio is largely dependent on economic factors, such as unemployment rates and housing prices.

Loans that do not share risk characteristics are evaluated on an individual basis based on various factors. Loans evaluated individually are not included in the collective evaluation. Factors that may be considered are borrower delinquency trends and nonaccrual status, probability of foreclosure or note sale, changes in the borrower’s circumstances or cash collections, borrower’s industry, or other facts and circumstances of the loan or collateral.

Individually Evaluated Loans with an ACL and Other Real Estate Owned: For collateral-dependent loans where the Company has determined that foreclosure of the collateral is probable, or where the borrower is experiencing financial difficulty and the Company expects repayment of the loan to be provided substantially through the operation or sale of the collateral, the ACL is measured based on the difference between the fair value of the collateral, less the estimated costs to sell, and the amortized cost basis of the loan as of the measurement date. The fair value of real estate collateral is determined based on recent appraised values. The fair value of other real estate owned is also determined based on recent appraised values less the estimated cost to sell. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach.

Adjustments to fair value are made only when the analysis indicates a probable decline in collateral values. Adjustments made in the appraisal process are not deemed material to the overall consolidated financial statements given the level of collateral dependent loans measured at fair value on a non-recurring basis.

Allowance for Credit Losses on Off-Balance Sheet Credit Exposures – The Company estimates expected credit losses over the contractual period in which the Company is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. The allowance for credit losses on off-balance sheet credit exposures, which is included in other liabilities on the consolidated statements of financial condition, is adjusted as a provision for credit loss expense in other operating expense. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life, which is the same as the expected loss factor as determined based on the corresponding portfolio segment.

Loans acquired in a business combination – The Company adopted ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, on January 1, 2021 which now requires the Company to record purchased financial assets with credit deterioration (PCD assets), defined as a more-than-insignificant deterioration in credit quality since origination or issuance, at the purchase price plus the allowance for credit losses expected at the time of acquisition. Under this method, there is no credit loss expense affecting net income on acquisition of PCD assets. Changes in estimates of expected losses after acquisition are recognized as credit loss expense (or reversal of credit loss expense) in subsequent periods as they arise. Any non-credit discount or premium resulting from acquiring a pool of purchased financial assets with credit deterioration shall be allocated to each individual asset. At the acquisition date, the initial allowance for credit losses determined on a collective basis shall be allocated to individual assets to appropriately allocate any non-credit discount or premium. The non-credit discount or premium, after the adjustment for the allowance for credit losses, shall be accreted to interest income using the interest method based on the effective interest rate determined after the adjustment for credit losses at the adoption date.

A purchased financial asset that does not qualify as a PCD asset is accounted for similar to an originated financial asset. Generally, this means that an entity recognizes the allowance for credit losses for non-PCD assets through net income at the time of acquisition. In addition, both the credit discount and non-credit discount or premium resulting from acquiring a pool of purchased financial assets that do not qualify as PCD assets shall be allocated to each individual asset. This combined discount or premium shall be accreted to interest income using the effective yield method.
