Accounting Policies [Abstract]
BASIS OF PRESENTATION AND CHANGES IN SIGNIFICANT ACCOUNTING POLICIES	BASIS OF PRESENTATION AND CHANGES IN SIGNIFICANT ACCOUNTING POLICIES Holding Company Reorganization On March 1, 2021 (the “Effective Date”), Amalgamated Financial Corp., a Delaware public benefit corporation (the “Company”) acquired all of the outstanding stock of Amalgamated Bank, a New York state-chartered bank (the “Bank”), in a statutory share exchange transaction (the “Reorganization”) effected under New York law and in accordance with the terms of a Plan of Acquisition dated September 4, 2020 (the “Agreement”). The Reorganization and the Agreement were approved by the Bank’s stockholders at a special meeting of the Bank’s stockholders held on January 12, 2021. Pursuant to the Reorganization, shares of the Bank’s Class A common stock were exchanged for shares of the Company’s common stock on a one-for-one basis. As a result, the Bank became the sole subsidiary of the Company, the Company became the holding company for the Bank and the stockholders of the Bank became stockholders of the Company. Prior to the Effective Date of the Reorganization, the Company conducted no operations other than obtaining regulatory approval for the Reorganization. Accordingly, there has been no significant financial activity at the parent company level as of March 31, 2021. In this discussion, unless the context indicates otherwise, references to “we,” “us,” and “our” refer to the Company and the Bank. However, if the discussion relates to a period before the Effective Date, the terms refer only to the Bank. Segment Information Public companies are required to report certain financial information about significant revenue-producing segments of the business for which such information is available and utilized by the chief operating decision maker. Substantially all of our operations occur through the Bank and involve the delivery of loan and deposit products to customers. Management makes operating decisions and assesses performance based on an ongoing review of its banking operation, which constitutes our only operating segment for financial reporting purposes. We do not consider our trust and investment management business as a separate segment. Basis of Accounting and Changes in Significant Accounting Policies The accounting and reporting policies of Amalgamated Financial Corp. (the “Company”) conform to accounting principles generally accepted in the United States of America, or GAAP and predominant practices within the banking industry. The Company uses the accrual basis of accounting for financial statement purposes. The accompanying unaudited consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries and its majority-owned subsidiaries and have been prepared in accordance with instructions to Form 10-Q and therefore do not include all information and footnotes necessary for a fair presentation of financial position, results of operations, and cash flows in conformity with GAAP. All significant inter-company transactions and balances are eliminated in consolidation. In the opinion of management, all adjustments necessary for a fair presentation of the consolidated financial position and the results of operations for the interim periods presented have been included. A more detailed description of our accounting policies is included in the Annual Report on Form 10-K for the year ended December 31, 2020 (the “2020 Annual Report”). There have been no significant changes to our accounting policies, or the estimates made pursuant to those policies as described in our 2020 Annual Report. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes appearing in the 2020 Annual Report. Risks and Uncertainties The impact of the COVID-19 pandemic is fluid and continues to evolve, adversely affecting many of the Company’s clients. The Company’s business, financial condition and results of operations generally rely upon the ability of the Bank’s borrowers to repay their loans, the value of collateral underlying the Bank’s secured loans, and demand for loans and other products and services the Bank offers, which are highly dependent on the business environment in the Bank’s primary markets where it operates and in the United States as a whole. The unprecedented and rapid spread of COVID-19 and its associated impacts on trade (including supply chains and export levels), travel, employee productivity, unemployment, consumer spending, and other economic activities has resulted in less economic activity, and significant volatility and disruption in financial markets, and has had an adverse effect on the Company’s business, financial condition and results of operation. The effects of the COVID-19 pandemic have had, and are expected to continue to have, possibly materially, an adverse effect on the Company’s business, financial condition and results of operations. The ultimate extent of the impact of the COVID-19 pandemic on our business, financial condition and results of operations is currently uncertain and will depend on various developments and other factors, including the effect of governmental and private sector initiatives, the effect of the recent rollout of vaccinations for the virus, whether such vaccinations will be effective against any resurgence of the virus, including any new strain, and the ability for customers and businesses to return to their pre-pandemic routine. In addition, it is reasonably possible that certain significant estimates made in the Company’s financial statements could be materially and adversely impacted in the near term as a result of these conditions.

RECENT ACCOUNTING PRONOUNCEMENT

RECENT ACCOUNTING PRONOUNCEMENTS	3 Months Ended
	Mar. 31, 2021
Accounting Changes and Error Corrections [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS Accounting Standards Adopted in 2020 In June 2016, the FASB amended existing guidance for ASU 2017-04 , “Intangibles – Goodwill and Other (Topic 350)”, to simplify the subsequent measurement of goodwill. The amendment requires an entity to perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount of the reporting unit exceeds its fair value, not to exceed the total amount of goodwill allocated to that reporting unit. The amendments also eliminate the requirement for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. The amendments became effective for public business entities for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The amendments should be applied prospectively. An entity is required to disclose the nature of and reason for the change in accounting principle upon transition in the first annual period and in the interim period within the first annual period when the entity initially adopts the amendments. As a result of our acquisition of New Resource Bank (“NRB”) in the latter half of the second quarter of 2018, we elected June 30, 2019 as the beginning date for annual impairment testing. We adopted ASU 2017-04 during the second quarter of 2020 and performed our annual impairment test. Our estimated fair value was in excess of the carrying value and the Bank, as a sole reporting unit, was not at risk of failing the quantitative analysis. Adoption did not have an effect on our operating results or financial condition. Refer to Note 13 - Goodwill and Intangible Assets for further details. In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820)—Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement”, which improves the effectiveness of fair value measurement disclosures. The amendments modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement as follows: removes disclosure requirements for the amount and reasons for transfer between Level 1 and Level 2 assets and liabilities in the fair value hierarchy; modifies disclosure requirements for transfers into and out of Level 3 assets and liabilities in the fair value hierarchy; adds disclosure requirements for the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments in this update became effective for all entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Adoption of ASU 2018-13 did not have a material effect on our operating results or financial condition. Accounting Standards Effective in 2021 and onward In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 significantly changes the impairment model for most financial assets that are measured at amortized cost and certain other instruments from an incurred loss model to an expected loss model and provides for recording credit losses on available for sale debt securities through an allowance account. ASU 2016-13 also requires certain incremental disclosures. In October 2019, the FASB voted to extend the adoption date for entities eligible to be smaller reporting companies, public business entities (PBEs) that are not SEC filers, and entities that are not PBEs from January 1, 2020 to January 1, 2023. Based on our election as an Emerging Growth Company under the Jumpstart Our Business Startups Act to use the extended transition period for complying with any new or revised financial accounting standards, we currently anticipate a January 1, 2023 adoption date. In preparation, we have performed work in assessing and enhancing the technology environment and related data needs and availability. Additionally, a Management Committee comprised of members from multiple departments has been established to monitor our progress towards adoption. As adoption will require the implementation of significant changes to the existing credit loss estimation model and is dependent on the economic forecast, and given the length of time before our adoption date, evaluating the overall impact of the ASU on our Consolidated Financial Statements is not yet determinable. On January 7, 2021, the FASB has issued Accounting Standards Update (ASU) No. 2021-01, Reference Rate Reform (Topic 848): Scope. The new guidance amends the scope of ASU 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which was aimed at easing the potential accounting burden expected when global capital markets move away from the London Interbank Offered Rate ("LIBOR") (the benchmark interest rate banks use to make short-term loans to each other) and provided temporary, optional expedients and exceptions for applying accounting guidance to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. As the majority of our securities tied to LIBOR are expected to transition to the Secured Overnight Financing Rate

Equity [Abstract]
ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS)	ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS) The Company records unrealized gains and losses, net of taxes, on securities available for sale in other comprehensive income (loss) in the Consolidated Statements of Changes in Stockholders’ Equity. Gains and losses on securities available for sale are reclassified to operations as the gains or losses are recognized. Other-than-temporary impairment (“OTTI”) losses on debt securities are reflected in earnings as realized losses to the extent the impairment is related to credit losses.

In general, as market interest rates rise and/or credit spreads widen, the fair value of fixed rate securities will decrease, as market interest rates fall and/or credit spreads tighten, the fair value of fixed rate securities will increase. Management considers that the temporary impairment of the Company’s investments in trust preferred securities (“TruPs”) as of March 31, 2021 is primarily due to a widening of credit spreads since the time these investments were acquired, as well as market uncertainty for this class of investments. As of March 31, 2021, temporarily impaired TruPs consist of direct investments in the TruPs of two large financial institutions. As of March 31, 2021, the amortized cost and fair value of the Company’s investment in these TruPs was $14.6 million and $14.1 million, respectively. All of the TruPs were rated investment grade by not less than three nationally recognized statistical rating organization’s (“NRSROs”). All of the issues are current as to their dividend payments and management is not aware of a decision of any trust preferred issuer to exercise its option to defer dividend payments. As of March 31, 2021, excluding GSE and U.S. Treasury securities and TruPs, discussed above, temporarily impaired securities totaled $795.6 million with an unrealized loss of $4.5 million. With the exception of $451.6 million of PACE bonds which were not rated, the remaining securities were rated investment grade by at least one NRSRO with no ratings below investment grade. All issues were current as to their interest payments. Management considers that the temporary impairment of these investments as of March 31, 2021 is primarily due to an increase in market spreads since the time these investments were acquired. With respect to the Company’s security investments that are temporarily impaired as of March 31, 2021, management does not intend to sell these investments and does not believe it will be necessary to do so before anticipated recovery. The Company expects to collect all amounts due according to the contractual terms of these investments. Therefore, the Company does not consider these securities to be other-than-temporarily impaired at March 31, 2021. None of these positions or other securities held in the portfolio or sold during the year were purchased with the intent of selling them or would otherwise be classified as trading securities under ASC No. 320, Investments – Debt Securities. During the three months ended March 31, 2021, the Company recorded an OTTI loss of $2,693, compared to no OTTI loss for the same period in 2020. Events which may cause material declines in the fair value of debt investments may include, but are not limited to, deterioration of credit metrics, higher incidences of default, worsening liquidity, worsening global or domestic economic conditions or adverse regulatory action. Management does not believe that there are any cases of unrecorded OTTI as of March 31, 2021; however, it is possible that the Company may recognize OTTI in future periods.

The guidance interprets current accounting standards and indicates that a lender can conclude that a borrower is not experiencing financial difficulty if short-term modifications are made in response to COVID-19, such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant related to the loans in which the borrower is less than 30 days past due on its contractual payments at the time a modification program is implemented. The agencies confirmed in working with the staff of the FASB that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not TDRs. On March 27, 2020, the CARES Act was enacted to help the nation’s economy recover from the COVID-19 pandemic. The CARES Act provides $2.2 trillion of economy-wide financial stimulus in the form of financial aid to individuals, businesses, nonprofit entities, states, and municipalities. Under Section 4022 of the CARES Act, a borrower with a federally backed mortgage loan that is experiencing a financial hardship due to COVID-19 may request a forbearance (i.e., payment deferral), regardless of delinquency status, for up to 180 days, which may be extended for an additional 180 days at the borrower’s request. Before this relief was set to expire on December 31, 2020, the Consolidated Appropriations Act was signed into law, which extended the relief granted under the CARES act to the earlier of January 1, 2022 or 60 days after the national emergency is terminated. During this relief period, no fees, penalties, or interest beyond those scheduled or calculated as if the borrower had made all contractual payments on time and in full will accrue. In addition, Section 4013 of the CARES Act provides temporary relief from the accounting and reporting requirements for TDRs regarding certain loan modifications related to COVID-19. Specifically, the CARES Act provides that a financial institution may elect to suspend the requirements under GAAP for certain loan modifications that would otherwise be categorized as a TDR. Modifications that qualify for this exception include a forbearance arrangement, an interest rate modification, a repayment plan, or any other similar arrangement that defers or delays the payment of principal or interest, that occurs for a loan that was not more than 30 days past due as of December 31, 2019. As of March 31, 2021, the Company had $8.5 million in loans on payment deferral and still accruing interest, of which $4.9 million were residential loans and the remaining $3.6 million were commercial or consumer loans.

In addition, residential loans are classified utilizing an inter-agency methodology that incorporates the extent of delinquency. Assigned risk rating grades are continuously updated as new information is obtained.

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	FAIR VALUE OF FINANCIAL INSTRUMENTS Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assumptions are developed based on prioritizing information within a fair value hierarchy that gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data. A description of the disclosure hierarchy and the types of financial instruments recorded at fair value that management believes would generally qualify for each category are as follows: Level 1 - Valuations are based on quoted prices in active markets for identical assets or liabilities. Accordingly, valuation of these assets and liabilities does not entail a significant degree of judgment. Examples include most U.S. Government securities and exchange-traded equity securities. Level 2 - Valuations are based on either quoted prices in markets that are not considered to be active or significant inputs to the methodology that are observable, either directly or indirectly. Financial instruments in this level would generally include mortgage-related securities and other debt issued by GSEs, non-GSE mortgage-related securities, corporate debt, certain redeemable fund investments and certain trust preferred securities. Level 3 - Valuations are based on inputs to the methodology that are unobservable and significant to the fair value measurement. These inputs reflect management’s own judgments about the assumptions that market participants would use in pricing the assets and liabilities. The following summarizes those financial instruments measured at fair value in the Consolidated Statements of Financial Condition categorized by the relevant class of investment and level of the fair value hierarchy: March 31, 2021 (In thousands) Level 1 Level 2 Level 3 Total Available for sale securities: Mortgage-related: GSE residential certificates $ — $ 11,630 $ — $ 11,630 GSE CMOs — 367,775 — 367,775 GSE commercial certificates & CMO — 449,555 — 449,555 Non-GSE residential certificates — 12,611 — 12,611 Non-GSE commercial certificates — 62,117 — 62,117 Other debt: U.S. Treasury 203 — — 203 ABS — 722,966 — 722,966 Trust preferred — 14,062 — 14,062 Corporate — 48,005 — 48,005 Total assets carried at fair value $ 203 $ 1,688,721 $ — $ 1,688,924 December 31, 2020 (In thousands) Level 1 Level 2 Level 3 Total Available for sale securities: Mortgage-related: GSE residential certificates $ — $ 13,299 $ — $ 13,299 GSE CMOs — 366,421 — 366,421 GSE commercial certificates & CMO — 432,614 — 432,614 Non-GSE residential certificates — 33,384 — 33,384 Non-GSE commercial certificates — 44,968 — 44,968 U.S. Treasury 203 — — 203 ABS — 597,546 — 597,546 Trust preferred — 13,773 — 13,773 Corporate — 37,654 — 37,654 Total assets carried at fair value $ 203 $ 1,539,659 $ — $ 1,539,862 The following tables summarize assets measured at fair value on a non-recurring basis: March 31, 2021 (In thousands) Carrying Value Level 1 Level 2 Level 3 Estimated Fair Value Fair Value Measurements: Impaired loans $ 70,614 $ — $ — $ 70,614 $ 70,614 Other real estate owned 2,989 — — 3,017 3,017 $ 73,603 $ — $ — $ 73,631 $ 73,631 December 31, 2020 (In thousands) Carrying Value Level 1 Level 2 Level 3 Estimated Fair Value Fair Value Measurements: Impaired loans $ 67,433 $ — $ — $ 67,433 $ 67,433 Other real estate owned 307 — — 303 303 $ 67,740 $ — $ — $ 67,736 $ 67,736 The following table summarizes the financial statement basis and estimated fair values for significant categories of financial instruments: March 31, 2021 Carrying Value Level 1 Level 2 Level 3 Estimated Fair Value (In thousands) Financial assets: Cash and cash equivalents $ 504,923 $ 504,923 $ — $ — $ 504,923 Available for sale securities 1,688,924 203 1,688,721 — 1,688,924 Held to maturity securities 531,274 — 80,311 449,896 530,207 Loans held for sale 16,661 — — 16,661 16,661 Loans receivable, net 3,222,842 — — 3,297,624 3,297,624 Resell agreements 152,268 — — 152,268 152,268 Accrued interest and dividends receivable 21,465 — 21,465 — 21,465 Financial liabilities: Deposits payable on demand 5,455,389 — 5,455,389 — 5,455,389 Time deposits 264,678 — 264,981 — 264,981 Accrued interest payable 263 — 263 — 263 December 31, 2020 (In thousands) Carrying Value Level 1 Level 2 Level 3 Estimated Fair Value Financial assets: Cash and cash equivalents $ 38,769 $ 38,769 $ — $ — $ 38,769 Available for sale securities 1,513,409 203 1,539,659 — 1,539,862 Held to maturity securities 494,449 — 76,519 425,906 502,425 Loans held for sale 11,178 — — 11,178 11,178 Loans receivable, net 3,447,306 — — 3,566,742 3,566,742 Resell agreements 154,779 — — 154,779 154,779 Accrued interest and dividends receivable 23,970 — 23,970 — 23,970 Financial liabilities: Deposits payable on demand 5,066,687 — 5,066,687 — 5,066,687 Time deposits 272,025 — 272,451 — 272,451 Accrued interest payable 386 — 386 — 386

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS, CONTINGENCIES AND OFF BALANCE SHEET RISK	COMMITMENTS, CONTINGENCIES AND OFF BALANCE SHEET RISK Credit Commitments The Company is party to various credit related financial instruments with off balance sheet risk. The Company, in the normal course of business, issues such financial instruments in order to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Such commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the consolidated statements of financial condition. The following financial instruments were outstanding whose contract amounts represent credit risk as of the related periods: March 31, 2021 December 31, 2020 (In thousands) Commitments to extend credit $ 593,600 $ 455,541 Standby letters of credit 16,018 17,910 Total $ 609,618 $ 473,451 Commitments to extend credit are contracts to lend to a customer as long as there is no violation of any condition established in the contract. These commitments have fixed expiration dates and other termination clauses and generally require the payment of nonrefundable fees. Since a portion of the commitments are expected to expire without being drawn upon, the contractual principal amounts do not necessarily represent future cash requirements. The Company’s maximum exposure to credit risk is represented by the contractual amount of these instruments. These instruments represent ultimate exposure to credit risk only to the extent they are subsequently drawn upon by customers. Standby letters of credit are conditional lending commitments issued by the Company to guarantee the financial performance of a customer to a third party. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loan facilities to customers. The balance sheet carrying value of standby letters of credit approximates any nonrefundable fees received but not yet recorded as income. The Company considers this carrying value, which is not material, to approximate the estimated fair value of these financial instruments. The Company reserves for the credit risk inherent in off balance sheet credit commitments. This reserve, which is included in other liabilities, amounted to approximately $1.2 million as of March 31, 2021 and $1.2 million as of December 31, 2020. Investment Obligations The Bank is party to agreements with Pace Funding Group LLC, or PFG, for the purchase of up to $300 million of property assessed clean energy, or PACE, assessment securities by the fourth quarter of 2021. Additionally, the Bank has an additional obligation up to $25 million for other PACE related purchases. These investments are to be held in the Company's held-to-maturity investment portfolio. As of March 31, 2021, we had fulfilled $214.5 million of these obligations. As of December 31, 2020, the Bank had fulfilled $165.4 million of our obligation. The PACE assessments have equal-lien priority with property taxes and generally rank senior to first lien mortgages.

Leases [Abstract]
LEASES	LEASES The Bank as a lessee has operating leases primarily consisting of real estate arrangements where the Company operates its headquarters, branches and business production offices. All leases identified as in scope are accounted for as operating leases as of March 31, 2021. These leases are typically long-term leases and generally are not complicated arrangements or structures. Several of the leases contain renewal options at a rate comparable to the fair market value based on comparable analysis to similar properties in the Bank’s geographies. Real estate operating leases are presented as a Right-of-use (“ROU”) asset and a related Operating lease liability on the Consolidated Statements of Financial Condition. The ROU asset represents the Company’s right to use the underlying asset for the lease term and the lease liabilities represent the obligation to make lease payments arising from the lease. The Company applied its incremental borrowing rate (“IBR”) as the discount rate to the remaining lease payments to derive a present value calculation for initial measurement of the lease liability. The IBR reflects the interest rate the Company would have to pay to borrow on a collateralized basis over a similar term for an amount equal to the lease payments. Lease expense is recognized on a straight-line basis over the lease term. The following table summarizes our lease cost and other operating lease information: Three Months Ended Three Months Ended (In thousands) Operating lease cost $ 2,237 $ 3,488 Cash paid for amounts included in the measurement of Operating leases liability $ 2,514 $ 2,680 Weighted average remaining lease term on operating leases (in years) 5.5 6.3 Weighted average discount rate used for operating leases liability 3.27 % 3.25 % Note: Sublease income and variable income or expense considered immaterial The following table presents the remaining commitments for operating lease payments for the next five years and thereafter, as well as a reconciliation to the discounted Operating leases liability recorded in the Consolidated Statements of Financial Condition as of March 31, 2021: (In thousands) As of March 31, 2021 2021 remaining $ 7,293 2022 9,931 2023 9,818 2024 9,828 2025 9,851 Thereafter 8,912 Total undiscounted operating lease payments 55,633 Less: present value adjustment 4,576 Total Operating leases liability $ 51,057

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND INTANGIBLE ASSETS	GOODWILL AND INTANGIBLE ASSETS Goodwill In accordance with GAAP, the Bank performs an annual test as of June 30 to identify potential impairment of goodwill, or more frequently if events or circumstances indicate a potential impairment may exist. If the carrying amount of the Bank, as a sole reporting unit, including goodwill, exceeds its fair value, an impairment loss is recognized in an amount equal to that excess up to the amount of the recorded goodwill. The fair value of the Company was determined by using a combination of a market approach and an income approach under the framework established for measuring fair value under ASC 820. Under both approaches the estimated fair value of the Company was in excess of the carrying value and the Bank, as a sole reporting unit, was not at risk of failing the quantitative analysis. The fair value is based upon market data as of June 30, 2020 and estimates and assumptions that the Company believes are most appropriate for the analysis. However, changes in certain assumptions used in the Company’s calculations could result in significant differences in the results of the impairment test. Should market conditions or management’s assumptions change significantly in the future, an impairment to goodwill is possible. As of March 31, 2021, there were no changes to the Company's annual impairment test conclusion. At March 31, 2021 and December 31, 2020, the carrying amount of goodwill was $12.9 million. Intangible Assets The following table reflects the estimated amortization expense, comprised entirely by the Bank’s core deposit intangible asset, for the next five years and thereafter: (In thousands) 2021 remaining $ 905 2022 1,047 2023 888 2024 730 2025 574 Thereafter 913 Total $ 5,057 Accumulated amortization of the core deposit intangible was $4.0 million as of March 31, 2021.

Substantially all of our operations occur through the Bank and involve the delivery of loan and deposit products to customers. Management makes operating decisions and assesses performance based on an ongoing review of its banking operation, which constitutes our only operating segment for financial reporting purposes. We do not consider our trust and investment management business as a separate segment.
Basis of Accounting	The accounting and reporting policies of Amalgamated Financial Corp. (the “Company”) conform to accounting principles generally accepted in the United States of America, or GAAP and predominant practices within the banking industry. The Company uses the accrual basis of accounting for financial statement purposes.

In the opinion of management, all adjustments necessary for a fair presentation of the consolidated financial position and the results of operations for the interim periods presented have been included. A more detailed description of our accounting policies is included in the Annual Report on Form 10-K for the year ended December 31, 2020 (the “2020 Annual Report”). There have been no significant changes to our accounting policies, or the estimates made pursuant to those policies as described in our 2020 Annual Report. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes appearing in the 2020 Annual Report.
Risks and Uncertainties	The impact of the COVID-19 pandemic is fluid and continues to evolve, adversely affecting many of the Company’s clients. The Company’s business, financial condition and results of operations generally rely upon the ability of the Bank’s borrowers to repay their loans, the value of collateral underlying the Bank’s secured loans, and demand for loans and other products and services the Bank offers, which are highly dependent on the business environment in the Bank’s primary markets where it operates and in the United States as a whole. The unprecedented and rapid spread of COVID-19 and its associated impacts on trade (including supply chains and export levels), travel, employee productivity, unemployment, consumer spending, and other economic activities has resulted in less economic activity, and significant volatility and disruption in financial markets, and has had an adverse effect on the Company’s business, financial condition and results of operation. The effects of the COVID-19 pandemic have had, and are expected to continue to have, possibly materially, an adverse effect on the Company’s business, financial condition and results of operations. The ultimate extent of the impact of the COVID-19 pandemic on our business, financial condition and results of operations is currently uncertain and will depend on various developments and other factors, including the effect of governmental and private sector initiatives, the effect of the recent rollout of vaccinations for the virus, whether such vaccinations will be effective against any resurgence of the virus, including any new strain, and the ability for customers and businesses to return to their pre-pandemic routine. In addition, it is reasonably possible that certain significant estimates made in the Company’s financial statements could be materially and adversely impacted in the near term as a result of these conditions.
Recent Accounting Pronouncements	Accounting Standards Adopted in 2020 In June 2016, the FASB amended existing guidance for ASU 2017-04 , “Intangibles – Goodwill and Other (Topic 350)”, to simplify the subsequent measurement of goodwill. The amendment requires an entity to perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount of the reporting unit exceeds its fair value, not to exceed the total amount of goodwill allocated to that reporting unit. The amendments also eliminate the requirement for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. The amendments became effective for public business entities for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The amendments should be applied prospectively. An entity is required to disclose the nature of and reason for the change in accounting principle upon transition in the first annual period and in the interim period within the first annual period when the entity initially adopts the amendments. As a result of our acquisition of New Resource Bank (“NRB”) in the latter half of the second quarter of 2018, we elected June 30, 2019 as the beginning date for annual impairment testing. We adopted ASU 2017-04 during the second quarter of 2020 and performed our annual impairment test. Our estimated fair value was in excess of the carrying value and the Bank, as a sole reporting unit, was not at risk of failing the quantitative analysis. Adoption did not have an effect on our operating results or financial condition. Refer to Note 13 - Goodwill and Intangible Assets for further details. In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820)—Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement”, which improves the effectiveness of fair value measurement disclosures. The amendments modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement as follows: removes disclosure requirements for the amount and reasons for transfer between Level 1 and Level 2 assets and liabilities in the fair value hierarchy; modifies disclosure requirements for transfers into and out of Level 3 assets and liabilities in the fair value hierarchy; adds disclosure requirements for the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments in this update became effective for all entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Adoption of ASU 2018-13 did not have a material effect on our operating results or financial condition. Accounting Standards Effective in 2021 and onward In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 significantly changes the impairment model for most financial assets that are measured at amortized cost and certain other instruments from an incurred loss model to an expected loss model and provides for recording credit losses on available for sale debt securities through an allowance account. ASU 2016-13 also requires certain incremental disclosures. In October 2019, the FASB voted to extend the adoption date for entities eligible to be smaller reporting companies, public business entities (PBEs) that are not SEC filers, and entities that are not PBEs from January 1, 2020 to January 1, 2023. Based on our election as an Emerging Growth Company under the Jumpstart Our Business Startups Act to use the extended transition period for complying with any new or revised financial accounting standards, we currently anticipate a January 1, 2023 adoption date. In preparation, we have performed work in assessing and enhancing the technology environment and related data needs and availability. Additionally, a Management Committee comprised of members from multiple departments has been established to monitor our progress towards adoption. As adoption will require the implementation of significant changes to the existing credit loss estimation model and is dependent on the economic forecast, and given the length of time before our adoption date, evaluating the overall impact of the ASU on our Consolidated Financial Statements is not yet determinable. On January 7, 2021, the FASB has issued Accounting Standards Update (ASU) No. 2021-01, Reference Rate Reform (Topic 848): Scope. The new guidance amends the scope of ASU 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which was aimed at easing the potential accounting burden expected when global capital markets move away from the London Interbank Offered Rate ("LIBOR") (the benchmark interest rate banks use to make short-term loans to each other) and provided temporary, optional expedients and exceptions for applying accounting guidance to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. As the majority of our securities tied to LIBOR are expected to transition to the Secured Overnight Financing Rate
Fair Value of Financial Instruments	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assumptions are developed based on prioritizing information within a fair value hierarchy that gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data. A description of the disclosure hierarchy and the types of financial instruments recorded at fair value that management believes would generally qualify for each category are as follows: Level 1 - Valuations are based on quoted prices in active markets for identical assets or liabilities. Accordingly, valuation of these assets and liabilities does not entail a significant degree of judgment. Examples include most U.S. Government securities and exchange-traded equity securities. Level 2 - Valuations are based on either quoted prices in markets that are not considered to be active or significant inputs to the methodology that are observable, either directly or indirectly. Financial instruments in this level would generally include mortgage-related securities and other debt issued by GSEs, non-GSE mortgage-related securities, corporate debt, certain redeemable fund investments and certain trust preferred securities.
