Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business, Organization and Basis of Presentation	Description of Business, Organization and Basis of Presentation Organization New York Community Bancorp, Inc. (on a stand-alone basis, the “Parent Company” or, collectively with its subsidiaries, the “Company” or "we") was organized under Delaware law on July 20, 1993 and is the holding company for Flagstar Bank N.A. (hereinafter referred to as the “Bank”). The Company is headquartered in Hicksville, New York with regional headquarters in Troy, Michigan. The Company is subject to regulation, examination and supervision by the Federal Reserve. The Bank is a National Association, subject to federal regulation and oversight by the OCC. On November 23, 1993, the Company issued its initial offering of common stock (par value: $0.01 per share) at a price of $25.00 per share ($0.93 per share on a split-adjusted basis, reflecting the impact of nine stock splits between 1994 and 2004). The Company has grown organically and through a series of accretive mergers and acquisitions, culminating in its acquisition of Flagstar Bancorp, Inc., which closed on December 1, 2022 and the Signature Transaction which closed on March 20, 2023. Flagstar Bank, N.A. currently operates 420 branches across twelve states, including strong footholds in the Northeast and Midwest and exposure to markets in the Southeast and West Coast. Flagstar Mortgage operates nationally through a wholesale network of approximately 3,600 third-party mortgage originators. Flagstar Bank N.A. also operates through nine local divisions, each with a history of service and strength: New York Community Bank, Queens County Savings Bank, Roslyn Savings Bank, Richmond County Savings Bank, Roosevelt Savings Bank, and Atlantic Bank in New York; Garden State Community Bank in New Jersey; Ohio Savings Bank in Ohio; and AmTrust Bank in Arizona and Florida. Liquidity On a consolidated basis, our funding primarily stems from a combination of the following sources: retail, institutional, and brokered deposits; borrowed funds, primarily in the form of wholesale borrowings; cash flows generated through the repayment and sale of loans; and cash flows generated through the repayment and sale of securities. We manage our liquidity to ensure that our cash flows are sufficient to support our operations, to compensate for any temporary mismatches between sources and uses of funds caused by variable loan and deposit demand, and to ensure that sufficient funds are available to meet our financial obligations. See Note 22 - Subsequent Events for further information on our recent capital raise. Basis of Presentation The following is a description of the significant accounting and reporting policies that the Company and its subsidiaries follow in preparing and presenting their consolidated financial statements, which conform to U.S. generally accepted accounting principles and to general practices within the banking industry. The preparation of financial statements in conformity with GAAP requires the Company to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Estimates are used in connection with the determination of the allowance for credit losses, mortgage servicing rights, the Flagstar acquisition and the Signature Transaction. The accompanying consolidated financial statements include the accounts of the Company and other entities in which the Company has a controlling financial interest. All inter-company accounts and transactions are eliminated in consolidation. The Company currently has certain unconsolidated subsidiaries in the form of wholly-owned statutory business trusts, which were formed to issue guaranteed capital securities. See Note 12 - Borrowed Funds for additional information regarding these trusts. When necessary, certain reclassifications have been made to prior-year amounts to conform to the current-year presentation. Loans Effective January 1, 2023, the Company adopted the provisions of Accounting Standards Update (ASU) No. 2022-02, "Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures" (ASU 2022-02), which eliminated the accounting for troubled debt restructurings (TDRs) while expanding loan modification and vintage disclosure requirements. Under ASU 2022-02, the Corporation assesses all loan modifications to determine whether one is granted to a borrower experiencing financial difficulty, regardless of whether the modified loan terms include a concession. Modifications granted to borrowers experiencing financial difficulty may be in the form of an interest rate reduction, an other-than-insignificant payment delay, a term extension, principal forgiveness or a combination thereof (collectively referred to as Troubled Debt Modifications or TDMs). Prior to the adoption of ASU 2022-02, the Company accounted for certain loan modifications and restructurings as TDRs. In general, a modification or restructuring of a loan constituted a TDR if the Company granted a concession to a borrower experiencing financial difficulty. Adoption of New Accounting Standards Standard Description Effective Date ASU 2022-02- Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures Issued March 2022 ASU 2022-02 eliminates prior accounting guidance for TDRs, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. The standard also requires that an entity disclose current-period gross charge-offs by year of origination for financing receivables and net investments in leases. The Company adopted ASU 2022-02 effective January 1, 2023 using a modified retrospective transition approach for the amendments related to the recognition and measurement of TDRs. The impact of the adoption resulted in an immaterial change to the allowance for credit losses ("ACL"), thus no adjustment to retained earnings was recorded. Disclosures have been updated to reflect information on loan modifications given to borrowers experiencing financial difficulty as presented in Note 6. TDR disclosures are presented for comparative periods only and are not required to be updated in current periods. Additionally, the current year vintage disclosure included in Note 6 has been updated to reflect gross charge-offs by year of origination for the three months ended September 30, 2023. ASU 2023-02 Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method Issued: March 2023 ASU 2023-02 permits reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. The Company adopted ASU 2023-02 effective January 1, 2023 and it did not have a significant impact on the Company's consolidated financial statements.

At December 31, 2023 and 2022, the Company’s cash and cash equivalents totaled $11.5 billion and $2.0 billion, respectively. Included in cash and cash equivalents at those dates were $10.7 billion and $837 million , respectively, of interest-bearing deposits in other financial institutions, primarily consisting of balances due from the FRB-NY. There were no reverse repurchase agreements outstanding as of December 31, 2023 and $793 million of reverse repurchase agreements were outstanding at December 31, 2022. There were no federal funds sold outstanding at December 31, 2023 or December 31, 2022. Restricted cash totaled $134 million and $50 million at December 31, 2023 and December 31, 2022, respectively and includes cash that the Bank pledges as maintenance margin on centrally cleared derivatives and is included in other assets on the Consolidated Statements of Condition. Debt Securities and Equity Investments with Readily Determinable Fair Values The securities portfolio primarily consists of mortgage-related securities and, to a lesser extent, debt and equity securities. Securities that are classified as “available for sale” are carried at their estimated fair value, with any unrealized gains or losses, net of taxes, reported as accumulated other comprehensive income or loss in stockholders’ equity. Securities that the Company has the intent and ability to hold to maturity are classified as “held to maturity” and carried at amortized cost. The fair values of our securities—and particularly our fixed-rate securities—are affected by changes in market interest rates and credit spreads. In general, as interest rates rise and/or credit spreads widen, the fair value of fixed-rate securities will decline. As interest rates fall and/or credit spreads tighten, the fair value of fixed-rate securities will rise. The Company evaluates available-for-sale debt securities in unrealized loss positions at least quarterly to determine if an allowance for credit losses is required. Based on an evaluation of available information about past events, current conditions, and reasonable and supportable forecasts that are relevant to collectability, the Company has concluded that it expects to receive all contractual cash flows from each security held in its available-for-sale securities portfolio. The Company first assesses whether (i) it intends to sell, or (ii) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. If either of these criteria is met, any previously recognized allowances are charged off and the security’s amortized cost basis is written down to fair value through income. If neither of the aforementioned criteria are met, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Management has made the accounting policy election to exclude accrued interest receivable on available-for-sale securities from the estimate of credit losses. Available-for-sale debt securities are placed on non-accrual status when the Company no longer expects to receive all contractual amounts due, which is generally at 90 days past due. Accrued interest receivable is reversed against interest income when a security is placed on non-accrual status. Equity investments with readily determinable fair values are measured at fair value with changes in fair value recognized in net income. Premiums and discounts on securities are amortized to expense and accreted to income over the remaining period to contractual maturity using the interest method, and are adjusted for anticipated prepayments. Dividend and interest income are recognized when earned. The cost of securities sold is based on the specific identification method. Federal Home Loan Bank Stock As a member of the FHLB-NY, the Company is required to hold shares of FHLB-NY stock, which is carried at cost. In addition, in connection with the Flagstar acquisition, the Company also holds shares of FHLB-Indianapolis stock, which is carried at cost. The Company’s holding requirement varies based on certain factors, including its outstanding borrowings from the FHLB-NY and FHLB-Indianapolis. The Company conducts a periodic review and evaluation of its FHLB-NY stock to determine if any impairment exists. The factors considered in this process include, among others, significant deterioration in FHLB-NY earnings performance, credit rating, or asset quality; significant adverse changes in the regulatory or economic environment; and other factors that could raise significant concerns about the creditworthiness and the ability of the FHLB-NY to continue as a going concern. Loans Held-for-Sale The Company classifies loans as LHFS when we originate or purchase loans that we intend to sell. We have elected the fair value option for the majority of our LHFS. The Company estimates the fair value of mortgage loans based on quoted market prices for securities backed by similar types of loans, where available, or by discounting estimated cash flows using observable inputs inclusive of interest rates, prepayment speeds and loss assumptions for similar collateral. Changes in fair value are recorded to other noninterest income on the Consolidated Statements of Income and Comprehensive Income. LHFS that are recorded at the lower of cost or fair value may be carried at fair value on a nonrecurring basis when the fair value is less than cost. For further information, see Note 18 - Fair Value Measures . Loans that are transferred into the LHFS portfolio from the LHFI portfolio, due to a change in intent, are recorded at the lower of cost or fair value. Gains or losses recognized upon the sale of loans are determined using the specific identification method. Loans Held for Investment Loans and leases, net, are carried at unpaid principal balances, including unearned discounts, purchase accounting (i.e., acquisition-date fair value) adjustments, net deferred loan origination costs or fees, and the allowance for credit losses on loans and leases. The Company recognizes interest income on loans using the interest method over the life of the loan. Accordingly, the Company defers certain loan origination and commitment fees, and certain loan origination costs, and amortizes the net fee or cost as an adjustment to the loan yield over the term of the related loan. When a loan is sold or repaid, the remaining net unamortized fee or cost is recognized in interest income. Prepayment income on loans is recorded in interest income and only when cash is received. Accordingly, there are no assumptions involved in the recognition of prepayment income. Two factors are considered in determining the amount of prepayment income: the prepayment penalty percentage set forth in the loan documents, and the principal balance of the loan at the time of prepayment. The volume of loans prepaying may vary from one period to another, often in connection with actual or perceived changes in the direction of market interest rates. When interest rates are declining, rising precipitously, or perceived to be on the verge of rising, prepayment income may increase as more borrowers opt to refinance and lock in current rates prior to further increases taking place. A loan generally is classified as a “non-accrual” loan when it is 90 days or more past due or when it is deemed to be impaired because the Company no longer expects to collect all amounts due according to the contractual terms of the loan agreement. When a loan is placed on non-accrual status, management ceases the accrual of interest owed, and previously accrued interest is charged against interest income. A loan is generally returned to accrual status when the loan is current and management has reasonable assurance that the loan will be fully collectible. Interest income on non-accrual loans is recorded when received in cash. Loans with Government Guarantees The Company originates government guaranteed loans which are pooled and sold as Ginnie Mae MBS. Pursuant to Ginnie Mae servicing guidelines, the Company has the unilateral right to repurchase loans securitized in Ginnie Mae pools that are due, but unpaid, for three consecutive months. As a result, once the delinquency criteria have been met, and regardless of whether the repurchase option has been exercised, the Company accounts for the loans as if they had been repurchased. The Company recognizes the loans and corresponding liability as loans with government guarantees and loans with government guarantees repurchase options, respectively, in the Consolidated Statements of Condition. If the loan is repurchased, the liability is cash settled and the loan with government guarantee remains. Once repurchased, the Company works to cure the outstanding loans such that they are re-eligible for sale or may begin foreclosure and recover losses through a claims process with the government agency, as an approved lender. Allowance for Credit Losses on Loans and Leases The allowance for credit losses on loans and leases is deducted from the amortized cost basis of a financial asset or a group of financial assets so that the balance sheet reflects the net amount the Company expects to collect. Amortized cost is the unpaid loan balance, net of deferred fees and expenses, and includes negative escrow. Subsequent changes (favorable and unfavorable) in expected credit losses are recognized immediately in net income as a credit loss expense or a reversal of credit loss expense. Management estimates the allowance by projecting and multiplying together the probability-of-default, loss- given-default and exposure-at-default depending on economic parameters for each month of the remaining contractual term, as well as credit ratings for certain loans within the commercial and industrial portfolio. The Company loss drivers for certain loans in the commercial and industrial portfolio are derived using leverages economic projections including property market and prepayment forecasts from established independent third parties, as well as credit ratings for certain loans within the commercial and industrial portfolio, to inform its loss drivers in the forecast. The Company estimates the exposure-at-default using prepayment models which forecasts prepayments over the life of the loans and leases. The economic forecast and the related economic parameters are developed using available information relating to past events, current conditions, multiple economic forecasts scenarios, including related weightings, over the reasonable and supportable forecast period and macroeconomic assumptions. The economic forecast scenarios and related economic parameters are sourced from independent third parties. The economic forecast reasonable and supportable period is 24 months, and afterwards the Company reverts to a historical average loss rate on a straight-line basis over a 12-month period. Historical credit loss experience over the historical loss observation period provides the basis for the estimation of expected credit losses, with qualitative factor adjustments made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, current collateral valuations, delinquency levels and terms, as well as for changes in environmental conditions, such as changes in legislation, regulation, policies, administrative practices or other relevant factors. Expected credit losses are estimated over the contractual term of the loans, adjusted for forecasted prepayments when appropriate. The contractual term excludes potential extensions or renewals. The methodology used in the estimation of the allowance for credit losses on loan and leases, which is performed at least quarterly, is designed to be dynamic and responsive to changes in portfolio credit quality and forecasted economic conditions. Each quarter the Company reassesses the appropriateness of the economic forecasting period, the reversion period and historical mean at the portfolio segment level, considering any required adjustments for differences in underwriting standards, portfolio mix, and other relevant data shifts over time. The allowance for credit losses on loans and leases is measured on a collective (pool) basis when similar risk characteristics exist. The portfolio segment represents the level at which a systematic methodology is applied to estimate credit losses. Management believes the products within each of the entity’s portfolio segments exhibit similar risk characteristics. The Company leverages economic projections including property market and prepayment forecasts from established independent third parties, as well as credit ratings for certain loans within the commercial and industrial portfolio, to inform its loss drivers in the forecast. Loans that do not share risk characteristics are evaluated on an individual basis. These include loans that are in nonaccrual status with balances above management determined materiality thresholds depending on loan class and also loans that are designated as TDR or “reasonably expected TDR” (criticized, classified, or maturing loans that will have a modification processed within the next three months). If a loan is determined to be collateral dependent, or meets the criteria to apply the collateral dependent practical expedient, expected credit losses are determined based on the fair value of the collateral at the reporting date, less costs to sell as appropriate. The Company maintains an allowance for credit losses on off-balance sheet credit exposures. At December 31, 2023 and December 31, 2022, the allowance for credit losses on off-balance sheet exposures was $52 million and $23 million, respectively. 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 is adjusted as a provision for credit losses 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 their estimated life. The Company examined historical CCF trends to estimate utilization rates, and chose an appropriate mean CCF based on both management judgment and quantitative analysis. Quantitative analysis involved examination of CCFs over a range of fund-up windows (between 12 and 36 months) and comparison of the mean CCF for each fund-up window with management judgment determining whether the highest mean CCF across fund-up windows made business sense. The Company applies the same standards and estimated loss rates to the credit exposures as to the related class of loans. When applying this critical accounting estimate, we incorporate several inputs and judgments that may be influenced by changes period to period. These include, but are not limited to changes in the economic environment and forecasts, changes in the credit profile and characteristics of the loan portfolio, and changes in prepayment assumptions which will result in provisions to or recoveries from the balance of the allowance for credit losses. While changes to the economic environment forecasts and portfolio characteristics will change from period to period, portfolio prepayments are an integral assumption in estimating the allowance for credit losses on our commercial real estate (multi-family, CRE and ADC) portfolio which comprises 60 percent of the loan portfolio at December 31, 2023. Portfolio prepayments are subject to estimation uncertainty and changes in this assumption could have a material impact to our estimation process. Prepayment assumptions are sensitive to interest rates and existing loan terms and determine the weighted average life of the commercial mortgage loan portfolio. Excluding other factors, as the weighted average life of the portfolio increases or decreases, so will the required amount of the allowance for credit losses on commercial real estate. Goodwill The Company evaluates goodwill for impairment at least annually or when triggering events are identified. We utilize a market approach to determine the fair value of our single reporting unit, which considers how a market participant would view a control premium, complemented by an income approach if deemed necessary. The resulting value is then compared to our book value and any shortfalls would be recorded as an impairment. As of December 31, 2023, the Company identified a triggering event and applied a market approach using the end of day stock price, control premium for completed bank acquisitions, and an adjustment for Company-specific risk considerations based on subsequent confirming market evidence. This adjusted market capitalization was then compared to the carrying value to determine the extent of any shortfall which was calculated to be in excess of the goodwill balance. The Company’s assessment concluded that goodwill from historical transactions (2007 and prior) was fully impaired as of December 31, 2023, as confirmed by the Company’s current market capitalization. As a result, the Company recorded an impairment charge of the entire goodwill balance of $2.4 billion. Additional information on the methodologies and assumptions used in the goodwill impairment analysis can be found in Note 16 - Intangible Assets. Mortgage Servicing Rights The Company purchases and originates mortgage loans for sale to the secondary market and sell the loans on either a servicing-retained or servicing-released basis. If the Company retains the right to service the loan, an MSR is created at the time of sale which is recorded at fair value. The Company uses an internal valuation model that utilizes an option-adjusted spread, constant prepayment speeds, costs to service and other assumptions to determine the fair value of MSRs. Management obtains third-party valuations of the MSR portfolio on a quarterly basis from independent valuation services to assess the reasonableness of the fair value calculated by our internal valuation model. Changes in the fair value of our MSRs are reported on the Consolidated Statements of Income and Comprehensive Income in net return on mortgage servicing. For further information, see Note 9 - Mortgage Servicing Rights and Note 18 - Fair Value Measures . Premises and Equipment, Net Premises, furniture, fixtures, and equipment are carried at cost, less the accumulated depreciation computed on a straight-line basis over the estimated useful lives of the respective assets (generally 20 years for premises and three Depreciation is included in “Occupancy and equipment expense” in the Consolidated Statements of Income and Comprehensive Income, and amounted to $39 million, $18 million, and $21 million, respectively, in the years ended December 31, 2023, 2022, and 2021. Accumulated depreciation as of December 31, 2023 and December 31, 2022 was $526 million and $434 million. The estimated useful lives for the principal classes of assets are as follows: Premises and Equipment Useful Lives Buildings 30 Furniture, fixtures and equipment, and building improvements 13.5 Leasehold improvements 10 ATMs 7 Bank-Owned Life Insurance The Company has purchased life insurance policies on certain employees. These BOLI policies are recorded in the Consolidated Statements of Condition at their cash surrender value. Income from these policies and changes in the cash surrender value are recorded in “Non-interest income” in the Consolidated Statements of Income and Comprehensive Income. At December 31, 2023 and 2022, the Company’s investment in BOLI was $1.6 billion. The Company’s investment in BOLI generated income of $43 million, $32 million, and $29 million, respectively, during the years ended December 31, 2023, 2022, and 2021. Variable Interest Entities An entity that has a controlling financial interest in a VIE is referred to as the primary beneficiary and consolidates the VIE. An entity is deemed to have a controlling financial interest and is the primary beneficiary of a VIE if it has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. For further information, see Note 10 - Variable Interest Entities . Repossessed Assets and OREO Repossessed assets consist of any property or other assets acquired through, or in lieu of, foreclosure are sold or rented, and are recorded at fair value, less the estimated selling costs, at the date of acquisition. Following foreclosure, management periodically performs a valuation of the asset, and the assets are carried at the lower of the carrying amount or fair value, less the estimated selling costs. Expenses and revenues from operations and changes in valuation, if any, are included in “General and administrative expense” in the Consolidated Statements of Income and Comprehensive Income. At December 31, 2023, the Company had $5 million of OREO, $4 million of taxi medallions and $5 million of repossessed specialty equipment. At December 31, 2022, the Company had $8 million of OREO and $4 million of taxi medallions. Servicing Fee Income Servicing fee income, late fees and ancillary fees received on loans for which the Company owns the MSR are included in net return on mortgage servicing rights on the Consolidated Statements of Income and Comprehensive Income. The fees are based on the outstanding principal and are recorded as income when earned. Subservicing fees, which are included in loan administration income on the Consolidated Statements of Income and Comprehensive Income, are based on a contractual monthly amount per loan including late fees and other ancillary income. Income Taxes Income tax expense consists of income taxes that are currently payable and deferred income taxes. Deferred income tax expense is determined by recognizing deferred tax assets and liabilities for future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates that are expected to apply to taxable income in years in which those temporary differences are expected to be recovered or settled. The Company assesses the deferred tax assets and establishes a valuation allowance when realization of a deferred asset is not considered to be “more likely than not.” The Company considers its expectation of future taxable income in evaluating the need for a valuation allowance. The Company estimates income taxes payable based on the amount it expects to owe the various tax authorities (i.e., federal, state, and local). Income taxes represent the net estimated amount due to, or to be received from, such tax authorities. In estimating income taxes, management assesses the relative merits and risks of the appropriate tax treatment of transactions, taking into account statutory, judicial, and regulatory guidance in the context of the Company’s tax position. In this process, management also relies on tax opinions, recent audits, and historical experience. Although the Company uses the best available information to record income taxes, underlying estimates and assumptions can change over time as a result of unanticipated events or circumstances such as changes in tax laws and judicial guidance influencing its overall tax position. Derivative Instruments and Hedging Activities The Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. The Company utilizes derivative instruments to manage the fair value changes in our MSRs, interest rate lock commitments and LHFS portfolio which are exposed to price and interest rate risk; facilitate asset/liability management; minimize the variability of future cash flows on long-term debt; and to meet the needs of our customers. All derivatives are recognized on the Consolidated Statements of Condition as other assets and liabilities, as applicable, at their estimated fair value. The Company uses interest rate swaps, swaptions, futures and forward loan sale commitments to mitigate the impact of fluctuations in interest rates and interest rate volatility on the fair value of the MSRs. Changes in their fair value are reflected in current period earnings under the net return on mortgage servicing asset. These derivatives are valued based on quoted prices for similar assets in an active market with inputs that are observable. The Company also enters into various derivative agreements with customers and correspondents in the form of interest rate lock commitments and forward purchase contracts which are commitments to originate or purchase mortgage loans whereby the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. The derivatives are valued using internal models that utilize market interest rates and other unobservable inputs. Changes in the fair value of these commitments due to fluctuations in interest rates are economically hedged through the use of forward loan sale commitments of MBS. The gains and losses arising from this derivative activity are reflected in current period earnings under the net gain on loan sales. To assist customers in meeting their needs to manage interest rate risk, the Company enters into interest rate swap derivative contracts. To economically hedge this risk, the Company enters into offsetting derivative contracts to effectively eliminate the interest rate risk associated with these contracts. For additional information regarding the accounting for derivatives, see Note 15 - Derivative and Hedging Activities and for additional information on recurring fair value disclosures, see Note 18 - Fair Value Measures . Representation and Warranty Reserve When the Company sells mortgage loans into the secondary mortgage market, it makes customary representations and warranties to the purchasers about various characteristics of each loan. Upon the sale of a loan, the Company recognizes a liability for that guarantee at its fair value as a reduction of our net gain on loan sales. Subsequent to the sale, the liability is re-measured at fair value on an ongoing basis based upon an estimate of probable future losses. An estimate of the fair value of the guarantee associated with the mortgage loans is recorded in other liabilities in the Consolidated Statements of Condition, and was $12 million and $10 million at December 31, 2023 and December 31, 2022, respectively . Stock-Based Compensation Under the New York Community Bancorp, Inc. 2020 Omnibus Incentive Plan (the “2020 Incentive Plan”), which was approved by the Company’s shareholders at its Annual Meeting on June 3, 2020, shares are available for grant as restricted stock or other forms of related rights. At December 31, 2023, the Company had 16,143,893 shares available for grant under the 2020 Incentive Plan. Compensation cost related to restricted stock grants is recognized on a straight-line basis over the vesting period. For a more detailed discussion of the Company’s stock-based compensation, see Note 14 - Stock-Related Benefits Plans. Retirement Plans The Company’s pension benefit obligations and post-retirement health and welfare benefit obligations, and the related costs, are calculated using actuarial concepts in accordance with GAAP. The measurement of such obligations and expenses requires that certain assumptions be made regarding several factors, most notably including the discount rate and the expected rate of return on plan assets. The Company evaluates these assumptions on an annual basis. Other factors considered by the Company in its evaluation include retirement patterns and mortality rates. Under GAAP, actuarial gains and losses, prior service costs or credits, and any remaining transition assets or obligations that have not been recognized under previous accounting standards must be recognized in AOCL until they are amortized as a component of net periodic benefit cost. Earnings per Common Share (Basic and Diluted) Basic EPS is computed by dividing the net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted EPS is computed using the same method as basic EPS, however, the computation reflects the potential dilution that would occur if outstanding in-the-money stock options were exercised and converted into common stock. Unvested stock-based compensation awards containing non-forfeitable rights to dividends paid on the Company’s common stock are considered participating securities, and therefore are included in the two-class method for calculating EPS. Under the two-class method, all earnings (distributed and undistributed) are allocated to common shares and participating securities based on their respective rights to receive dividends on the common stock. The Company grants restricted stock to certain employees under its stock-based compensation plan. Recipients receive cash dividends during the vesting periods of these awards, including on the unvested portion of such awards. Since these dividends are non-forfeitable, the unvested awards are considered participating securities and therefore have earnings allocated to them. The following table presents the Company’s computation of basic and diluted earnings per common share: For the Years Ended December 31, (in millions, except share and per share amounts) 2023 2022 2021 Net (loss) income available to common stockholders $ (112) $ 617 $ 563 Less: Dividends paid on and earnings allocated to participating securities (5) (8) (7) (Loss) earnings applicable to common stock $ (117) $ 609 $ 556 Weighted average common shares outstanding 713,643,550 483,603,395 463,865,661 (Loss) basic earnings per common share $ (0.16) $ 1.26 $ 1.20 (Loss) earnings applicable to common stock $ (117) $ 609 $ 556 Weighted average common shares outstanding 713,643,550 483,603,395 463,865,661 Potential dilutive common shares — 1,530,950 767,058 Total shares for diluted (loss) earnings per common share computation 713,643,550 485,134,345 464,632,719 Diluted (loss) earnings per common share and common share equivalents $ (0.16) $ 1.26 $ 1.20

Business Combinations

Business Combinations	12 Months Ended
	Dec. 31, 2023
Business Combination and Asset Acquisition [Abstract]
Business Combinations	Business Combinations Signature Bridge Bank On March 20, 2023, the Company’s wholly owned bank subsidiary, Flagstar Bank N.A. (the “Bank”), entered into a Purchase and Assumption Agreement (the “Agreement”) with the Federal Deposit Insurance Corporation (“FDIC”), as receiver (the "FDIC Receiver") of Signature Bridge Bank, N.A. (“Signature”) to acquire certain assets and assume certain liabilities of Signature (the “Signature Transaction”). Headquartered in New York, New York, Signature Bank was a full-service commercial bank that operated 29 branches in New York, seven branches in California, two branches in North Carolina, one branch in Connecticut, and one branch in Nevada. In connection with the Signature Transaction the Bank assumed all of Signature’s branches. The Bank acquired only certain parts of Signature it believes to be financially and strategically complementary that are intended to enhance the Company’s future growth. Pursuant to the terms of the Agreement, the Company was not required to make a cash payment to the FDIC on March 20, 2023 as consideration for the acquired assets and assumed liabilities. As the Company and the FDIC remain engaged in ongoing discussions which may impact the assets and liabilities acquired or assumed by the Company in the Signature Transaction. Any items identified that affect the bargain gain are recorded in the period they are identified. The Company may be required to make a payment to the FDIC or the FDIC may be required to make a payment to the Company on the Settlement Date, which will be one year after March 20, 2023, or as agreed upon by the FDIC and the Company. In addition, as part of the consideration for the Signature Transaction, the Company granted the FDIC equity appreciation rights in the common stock of the Company under an equity appreciation instrument (the "Equity Appreciation Instrument"). On March 31, 2023, the Company issued 39,032,006 shares of Company common stock to the FDIC pursuant to the Equity Appreciation Instrument. On May 19, 2023, the FDIC completed the secondary offering of those shares. The Company has determined that the Signature Transaction constitutes a business combination as defined by ASC 805, Business Combinations ("ASC 805"). ASC 805 establishes principles and requirements as to how the acquirer of a business recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed and any non-controlling interest in the acquiree. Accordingly, the assets acquired and liabilities assumed have been recorded based on their preliminary estimated fair values as of March 20, 2023, which have been adjusted through December 31, 2023 based on changes to those preliminary estimates. Under the Agreement, the Company is expected to provide certain services to the FDIC to assist the FDIC in its administration of certain assets and liabilities which were not assumed by the Company and which remain under the control of the FDIC (the “Interim Servicing”). The Interim Servicing includes activities related to the servicing of loan portfolios not acquired on behalf of the FDIC for a period of up to one year from the date of the Signature Transaction unless such loans are sold or transferred at an earlier time by the FDIC or until cancelled by the FDIC upon 60-days’ notice. The Interim Servicing may include other ancillary services requested by the FDIC to assist in their administration of the remaining assets and liabilities of Signature Bank. The FDIC will reimburse the Company for costs associated with the Interim Servicing based upon an agreed upon fee which approximates the cost to provide such services. As the FDIC intends to reimburse the Company for the costs to service the loans, neither a servicing asset nor servicing liability was recognized as part of the Signature Transaction. The Company did not enter into a loss sharing arrangement with the FDIC in connection with the Signature Transaction. As the Company finalizes its analysis of the assets acquired and liabilities assumed, there may be adjustments to the recorded carrying values. In many cases, the determination of the fair value of the assets acquired and liabilities assumed required management to make estimates about discount rates, future expected cash flows, market conditions and other future events that are highly subjective in nature and subject to change. While the Company believes that the information available on December 31, 2023, provided a reasonable basis for estimating fair value, the Company may obtain additional information and evidence during the measurement period that may result in changes to the estimated fair value amounts. Fair values subject to change include, but are not limited to, those related to loans and leases, certain deposits, intangibles, deferred tax assets and liabilities and certain other assets and other liabilities. A summary of the preliminary net assets acquired and related estimated fair value adjustments resulting in the bargain purchase gain is as follows: (in millions) March 20, 2023 (preliminary) Net assets acquired before fair value adjustments $ 2,973 Fair value adjustments: Loans (727) Core deposit and other intangibles 464 Certificates of deposit 27 Other net assets and liabilities 39 FDIC Equity Appreciation Instrument (85) Deferred tax liability (690) Bargain purchase gain on Signature Transaction, as initially reported 2,001 Measurement period adjustments, excluding taxes 28 Change in deferred tax liability 102 Bargain purchase gain on Signature Transaction, as adjusted $ 2,131 In connection with the Signature Transaction, the Company recorded a bargain purchase gain, as adjusted, of approximately $2.1 billion during the year ended December 31, 2023, which is included in non-interest income in the Company’s Consolidated Statement of Income and Comprehensive Income. The bargain purchase gain represents the excess of the estimated fair value of the assets acquired (including cash payments received from the FDIC) over the estimated fair value of the liabilities assumed and is influenced significantly by the FDIC-assisted transaction process. Under the FDIC-assisted transaction process, only certain assets and liabilities are transferred to the acquirer and, depending on the nature and amount of the acquirers bid, the FDIC may be required to make a cash payment to the Company and the Company may be required to make a cash payment to the FDIC. The assets acquired and liabilities assumed and consideration paid in the Signature Transaction were initially recorded at their estimated fair values based on management’s best estimates using information available at the date of the Signature Transaction, and are subject to adjustment for up to one year after the closing date of the Signature Transaction. The Company and the FDIC are engaged in ongoing discussions and settlement payments have been made that have impacted certain assets acquired or certain liabilities assumed by the Company on March 20, 2023 and are included as measurement period adjustments in the table below. (in millions) Preliminary as Initially Reported Measurement Period Adjustments Preliminary as Adjusted Purchase Price consideration $ 85 $ 85 Fair value of assets acquired: Cash & cash equivalents 25,043 (142) 24,901 Loans held for sale 232 232 Loans held for investment: Commercial and industrial 10,102 (214) 9,888 Commercial real estate 1,942 (262) 1,680 Consumer and other 174 (1) 173 Total loans held for investment 12,218 (477) 11,741 CDI and other intangible assets 464 — 464 Other assets 679 (169) 510 Total assets acquired 38,636 (788) 37,848 Fair value of liabilities assumed: Deposits 33,568 (61) 33,507 Other liabilities 2,982 (857) 2,125 Total liabilities assumed 36,550 (918) 35,632 Fair value of net identifiable assets 2,086 130 2,216 Bargain purchase gain $ 2,001 $ 130 $ 2,131 During the year ended December 31, 2023, the Company recorded preliminary measurement period adjustments to adjust the estimated fair value of loans and leases acquired and adjust other assets and accrued expenses and other liabilities for balances ultimately retained by the FDIC. Additionally, $449 million of loans were returned to the FDIC in accordance with the purchase and sale agreement. The Company also recognized a net change in the deferred tax liability due to the measurement period adjustments and the secondary offering of shares completed by the FDIC. The Company incurred $223 million in acquisition costs related to the Signature Transaction primarily for legal, advisory, and other professional services. These costs are recorded within Merger-related and restructuring expenses on the Consolidated Statements of Income and Comprehensive Income. Fair Value of Assets Acquired and Liabilities Assumed 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, reflecting assumptions that a market participant would use when pricing an asset or liability. In some cases, the estimation of fair values requires management to make estimates about discount rates, future expected cash flows, market conditions, and other future events that are highly subjective in nature and are subject to change. Described below are the methods used to determine the fair values of the significant assets acquired and liabilities assumed in the Signature Transaction. Cash and Cash Equivalents The estimated fair value of cash and cash equivalents approximates their stated face amounts, as these financial instruments are either due on demand or have short-term maturities. Loans and leases The fair value for loans was based on a discounted cash flow methodology that considered credit loss expectations, market interest rates and other market factors such as liquidity from the perspective of a market participant. Loans were grouped together according to similar characteristics and were treated in the aggregate when applying various valuation techniques. The probability of default, loss given default and prepayment assumptions were the key factors driving credit losses which were embedded into the estimated cash flows. These assumptions were informed by internal data on loan characteristics, historical loss experience, and current and forecasted economic conditions. The interest and liquidity component of the estimate was determined by discounting interest and principal cash flows through the expected life of each loan. The discount rates used for loans are based on current market rates for new originations of comparable loans and include adjustments for liquidity. The discount rates do not include a factor for credit losses as that has been included as a reduction to the estimated cash flows. Acquired loans were marked to fair value and adjusted for any PCD gross up as of the date of the Signature Transaction. Deposit Liabilities The fair value of deposit liabilities with no stated maturity (i.e., non-interest-bearing and interest-bearing checking accounts) is equal to the carrying amounts payable on demand. The fair value of certificates of deposit represents contractual cash flows, discounted using interest rates currently offered on deposits with similar characteristics and remaining maturities. Core Deposit Intangible Core deposit intangible (“CDI”) is a measure of the value of non-interest-bearing and interest-bearing checking accounts, savings accounts, and money market accounts that are acquired in a business combination. The fair value of the CDI was determined using a discounted cashflow methodology which considered discount rate, customer attrition rates, and other relevant market assumptions. This method estimated the fair value by discounting the present value of the expected cost savings attributable to the core deposit funding, relative to an alternative source of funding. The CDI relating to the Signature Transaction will be amortized over an estimated useful life of 10 years using the sum of years digits depreciation method. The Company evaluates such identifiable intangibles for impairment when an indication of impairment exists. CDI does not significantly impact our liquidity or capital ratios. PCD loans Purchased loans that reflect a more than insignificant deterioration of credit from origination are considered PCD. For PCD loans and leases, the initial estimate of expected credit losses is recognized in the allowance for credit losses (“ACL”) on the date of acquisition using the same methodology as other loans and leases held-for-investment. The following table provides a summary of loans and leases purchased as part of the Signature Transaction with credit deterioration and the associated credit loss reserve at acquisition: (in millions) Total Par value (UPB) $ 583 ACL at acquisition (13) Non-credit (discount) (76) Fair value $ 494 Unaudited Pro Forma Information – Signature Transaction The Company’s operating results for the year ended December 31, 2023 include the operating results of the acquired assets and assumed liabilities of Signature subsequent to the acquisition on March 20, 2023. Due to the use of multiple systems and integration of the operating activities into those of the Company, historical reporting for the former Signature operations is impracticable and thus disclosures of the revenue from the assets acquired and income before income taxes is impracticable for the period subsequent to acquisition. Signature was only in operation from March 12, 2023 to March 20, 2023 and does not have historical financial information on which we could base pro forma information. Additionally, we did not acquire all assets or assume all liabilities of Signature and the historical operations are not consistent with the transaction. Therefore, it is impracticable to provide pro forma information on revenues and earnings for the Signature Transaction in accordance with ASC 805-10-50-2. Flagstar Bancorp, Inc. On December 1, 2022, the Company closed the acquisition of Flagstar Bancorp, Inc. (“Flagstar”) in an all-stock transaction (“Flagstar Transaction”). Flagstar was a savings and loan holding company headquartered in Troy, MI. Pursuant to the terms of the Merger Agreement, each share of Flagstar common stock was converted into 4.0151 shares of the Company’s common shares at the effective time of the merger. In addition, the Company received approval from the Office of the Comptroller of the Currency (the “OCC") to convert Flagstar Bank, FSB to a national bank to be known as Flagstar Bank, N.A., and to merge New York Community Bank into Flagstar Bank, N.A. with Flagstar Bank, N.A. being the surviving entity. Flagstar Bank, FSB, provided commercial, small business, and consumer banking services through 158 branches in Michigan, Indiana, California, Wisconsin, and Ohio. It also provided home loans through a wholesale network of brokers and correspondents in all 50 states. The acquisition of Flagstar added significant scale, geographic diversification, improved funding profile, and a broader product mix to the Company. The acquisition of Flagstar has been accounted for as a business combination. The Company recorded the preliminary estimate of fair value of the assets acquired and liabilities assumed December 1, 2022, which was subject to adjustment for up to one year after December 1, 2022. As of December 31, 2023, the Company finalized its review of the assets acquired and liabilities assumed, and did not record any material adjustments. The following table provides an allocation of consideration paid for the fair value of assets acquired and liabilities and equity assumed from Flagstar as of December 1, 2022. (in millions) December 1, 2022 Purchase Price consideration $ 2,010 Fair value of assets acquired: Cash & cash equivalents 331 Securities 2,695 Loans held for sale 1,257 Loans held for investment: One-to-four family first mortgage 5,438 Commercial and industrial 3,891 Commercial real estate 6,523 Consumer and other 2,156 Total loans held for investment 18,008 CDI and other intangible assets 292 Mortgage servicing rights 1,012 Other assets 2,158 Total assets acquired 25,753 Fair value of liabilities assumed: Deposits 15,995 Borrowings 6,700 Other liabilities 889 Total liabilities assumed 23,584 Fair value of net identifiable assets 2,169 Bargain purchase gain $ 159 In connection with the acquisition, the Company recorded a bargain purchase gain of approximately $159 million. The Company incurred $99 million in acquisition costs related to the Flagstar Transaction primarily for legal, advisory, and other professional services. These costs are recorded within Merger-related and restructuring expenses on the Consolidated Statements of Income and Comprehensive Income. Fair Value of Assets Acquired and Liabilities Assumed 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, reflecting assumptions that a market participant would use when pricing an asset or liability. In some cases, the estimation of fair values requires management to make estimates about discount rates, future expected cash flows, market conditions, and other future events that are highly subjective in nature and are subject to change. Described below are the methods used to determine the fair values of the significant assets acquired and liabilities assumed in the Flagstar acquisition. Cash and Cash Equivalents The estimated fair value of cash and cash equivalents approximates their stated face amounts, as these financial instruments are either due on demand or have short-term maturities. Investment Securities and Federal Home Loan Bank Stock Quoted market prices for the securities acquired were used to determine their fair values. If quoted market prices were not available for a specific security, then quoted prices for similar securities in active markets were used to estimate the fair value. The fair value of FHLB-Indianapolis stock is equivalent to the redemption amount. Loans Fair values for loans were based on a discounted cash flow methodology that considered credit loss expectations, market interest rates and other market factors such as liquidity from the perspective of a market participant. Loans were grouped together according to similar characteristics and were treated in the aggregate when applying various valuation techniques. The probability of default, loss given default and prepayment assumptions were the key factors driving credit losses which were embedded into the estimated cash flows. These assumptions were informed by internal data on loan characteristics, historical loss experience, and current and forecasted economic conditions. The interest and liquidity component of the estimate was determined by discounting interest and principal cash flows through the expected life of each loan. The discount rates used for loans are based on current market rates for new originations of comparable loans and include adjustments for liquidity. The discount rates do not include a factor for credit losses as that has been included as a reduction to the estimated cash flows. Acquired loans were marked to fair value and adjusted for any PCD gross up as of the merger date. Core Deposit Intangible CDI is a measure of the value of non-interest-bearing and interest-bearing checking accounts, savings accounts, and money market accounts that are acquired in a business combination. The fair value of the CDI stemming from any given business combination is based on the present value of the expected cost savings attributable to the core deposit funding, relative to an alternative source of funding. The CDI relating to the Flagstar acquisition will be amortized over an estimated useful life of 10 years using the sum of years digits depreciation method. The Company evaluates such identifiable intangibles for impairment when an indication of impairment exists. Deposit Liabilities The fair value of deposit liabilities with no stated maturity (i.e., non-interest-bearing and interest-bearing checking accounts) is equal to the carrying amounts payable on demand. The fair value of certificates of deposit represents contractual cash flows, discounted using interest rates currently offered on deposits with similar characteristics and remaining maturities. Borrowed Funds The estimated fair value of borrowed funds is based on bid quotations received from securities dealers or the discounted value of contractual cash flows with interest rates currently in effect for borrowed funds with similar maturities. PCD loans Purchased loans that reflect a more than insignificant deterioration of credit from origination are considered PCD. For PCD loans and leases, the initial estimate of expected credit losses is recognized in the ACL on the date of acquisition using the same methodology as other loans and leases held-for-investment. The following table provides a summary of loans and leases purchased as part of the Flagstar acquisition with credit deterioration and the associated credit loss reserve at acquisition: (in millions) Total Par value (UPB) $ 1,950 ACL at acquisition (51) Non-credit (discount) (33) Fair value $ 1,866 Unaudited Pro Forma Information The Company’s results of operations for the year-ended December 31, 2022 and 2023 include the results of operations of Flagstar on and after December 1, 2022. Results for periods prior to December 1, 2022, do not include the results of operations of Flagstar. The following pro forma financial information presents the unaudited consolidated results of operations of the Company and Flagstar as if the Flagstar Transaction occurred as of January 1, 2021 with pro forma adjustments. The pro forma adjustments give effect to any change in interest income due to the accretion of the net discounts from the fair value adjustments of acquired loans, any change in interest expense due to the estimated net premium from the fair value adjustments to acquired time deposits and other debt, and the amortization of intangibles had the deposits been acquired as of January 1, 2021. The pro forma amounts for the years ended December 31, 2022 and 2021 do not reflect the anticipated cost savings that have not yet been realized. Acquisition costs incurred by the Company during the years ended December 31, 2022 and 2021 are reflected in the pro forma amounts. The pro forma information does not necessarily reflect the results of operations that would have occurred had the Flagstar Transaction occurred at the beginning of 2021. For the Years Ended December 31, (unaudited) (in millions) 2022 2021 Net interest income $ 2,278 $ 2,208 Non-interest income 650 1,105 Net income 804 1,207 Net income available to common stockholders $ 771 $ 1,174

The investment securities designated as having a continuous loss position for twelve months or more at December 31, 2022 consisted of twenty three agency collateralized mortgage obligations, five capital trusts notes, seven asset-backed securities, two corporate bonds, thirty three US government agency bonds, one hundred thirty three mortgage-backed securities, one mutual fund, and one municipal bond. The Company evaluates available-for-sale debt securities in unrealized loss positions at least quarterly to determine if an allowance for credit losses is required. We also assess whether (i) we intend to sell, or (ii) it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. If either of these criteria is met, any previously recognized allowances are charged off and the security’s amortized cost basis is written down to fair value through income. If neither of the aforementioned criteria are met, we evaluate whether the decline in fair value has resulted from credit losses or other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. In the first quarter of 2023, the Company held a $20 million corporate bond in Signature Bank which was placed into receivership on March 12, 2023. We have taken a $20 million provision for credit loss and charged-off this security during the three months ended March 31, 2023. None of the remaining unrealized losses identified as of December 31, 2023 or December 31, 2022 relates to the marketability of the securities or the issuers’ ability to honor redemption obligations. Rather, the unrealized losses relate to changes in interest rates relative to when the investment securities were purchased, and do not indicate credit-related impairment. Management based this conclusion on an analysis of each issuer including a detailed credit assessment of each issuer. The Company does not intend to sell, and it is not more likely than not that the Company will be required to sell the positions before the recovery of their amortized cost basis, which may be at maturity. As such, no allowance for credit losses remains with respect to debt securities as of December 31, 2023.

Loans and Leases	Loans and Leases The Company classifies loans that we have the intent and ability to hold for the foreseeable future or until maturity as LHFI. We report LHFI loans at their amortized cost, which includes the outstanding principal balance adjusted for any unamortized premiums, discounts, deferred fees and unamortized fair value adjustments for acquired loans: December 31, 2023 December 31, 2022 (dollars in millions) Amount Percent of Amount Percent of Loans and Leases Held for Investment: Mortgage Loans: Multi-family $ 37,265 44.0 % $ 38,130 55.3 % Commercial real estate 10,470 12.4 % 8,526 12.4 % One-to-four family first mortgage 6,061 7.2 % 5,821 8.4 % Acquisition, development, and construction 2,912 3.4 % 1,996 2.8 % Total mortgage loans held for investment (1) $ 56,708 67.0 % $ 54,473 78.9 % Other Loans: Commercial and industrial 22,065 26.1 % 10,597 15.4 % Lease financing, net of unearned income of $258 and $85, respectively 3,189 3.8 % 1,679 2.4 % Total commercial and industrial loans (2) 25,254 29.9 % 12,276 17.8 % Other 2,657 3.1 % 2,252 3.3 % Total other loans held for investment 27,911 33.0 % 14,528 21.1 % Total loans and leases held for investment (1) $ 84,619 100.0 % $ 69,001 100.0 % Allowance for credit losses on loans and leases (992) (393) Total loans and leases held for investment, net 83,627 68,608 Loans held for sale 1,182 1,115 Total loans and leases, net $ 84,809 $ 69,723 (1) Excludes accrued interest receivable of $423 million and $292 million at December 31, 2023 and December 31, 2022, respectively, which is included in other assets (2) Includes specialty finance loans and leases of $5.2 billion and $4.4 billion at December 31, 2023 and December 31, 2022, respectively. Loans with Government Guarantees Substantially all LGG are insured or guaranteed by the FHA or the U.S. Department of Veterans Affairs. Nonperforming repurchased loans in this portfolio earn interest at a rate based upon the 10-year U.S. Treasury note rate from the time the underlying loan becomes 60 days delinquent until the loan is conveyed to HUD (if foreclosure timelines are met), which is not paid by the FHA until claimed. The Bank has a unilateral option to repurchase loans sold to GNMA if the loan is due, but unpaid, for three consecutive months (typically referred to as 90 days past due) and can recover losses through a claims process from the guarantor. These loans are recorded in loans held for investment and the liability to repurchase the loans is recorded in other liabilities on the Consolidated Statements of Condition. Certain loans within our portfolio may be subject to indemnifications and insurance limits which expose us to limited credit risk. As of December 31, 2023, LGG loans totaled $541 million and the repurchase liability was $456 million. Repossessed assets and the associated net claims related to government guaranteed loans are recorded in other assets and was $14 million at December 31, 2023. Loans Held-for-Sale Loans held-for-sale at December 31, 2023 totaled $1.2 billion, up from $1.1 billion at December 31, 2022. The Signature Transaction contributed $360 million in Small Business Administration ("SBA") loans to this increase. We classify loans as held for sale when we originate or purchase loans that we intend to sell. We have elected the fair value option for nearly all of this portfolio, except the SBA loans. We estimate the fair value of mortgage loans based on quoted market prices for securities backed by similar types of loans, where available, or by discounting estimated cash flows using observable inputs inclusive of interest rates, prepayment speeds and loss assumptions for similar collateral. Asset Quality All asset quality information excludes LGG that are insured by U.S government agencies. A loan generally is classified as a non-accrual loan when it is 90 days or more past due or when it is deemed to be impaired because the Company no longer expects to collect all amounts due according to the contractual terms of the loan agreement. When a loan is placed on non-accrual status, management ceases the accrual of interest owed, and previously accrued interest is charged against interest income. A loan is generally returned to accrual status when the loan is current and management has reasonable assurance that the loan will be fully collectible. Interest income on non-accrual loans is recorded when received in cash. At December 31, 2023 and December 31, 2022 we had no loans that were nonperforming and still accruing.

In addition, they follow regulatory guidelines and can generally be described as follows: pass loans are of satisfactory quality; special mention loans have potential weaknesses that deserve management’s close attention; substandard loans are inadequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged (these loans have a well-defined weakness and there is a possibility that the Company will sustain some loss); and doubtful loans, based on existing circumstances, have weaknesses that make collection or liquidation in full highly questionable and improbable. In addition, one-to-four family loans are classified based on the duration of the delinquency.

When the borrower is experiencing financial difficulty at the reporting date and repayment is expected to be provided substantially through the operation or sale of the collateral, the collateral-dependent practical expedient has been elected and expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. For CRE loans, collateral properties include office buildings, warehouse/distribution buildings, shopping centers, apartment buildings, residential and commercial tract development. The primary source of repayment on these loans is expected to come from the sale, permanent financing or lease of the real property collateral. CRE loans are impacted by fluctuations in collateral values, as well as the ability of the borrower to obtain permanent financing. The following table summarizes the extent to which collateral secures the Company’s collateral-dependent loans held for investment by collateral type as of December 31, 2023: Collateral Type (in millions) Real Property Other Multi-family $ 253 $ — Commercial real estate 256 — One-to-four family first mortgage 105 — Commercial and industrial — 120 Total collateral-dependent loans held for investment $ 614 $ 120 Other collateral type consists of taxi medallions, cash, accounts receivable and inventory. There were no significant changes in the extent to which collateral secures the Company’s collateral-dependent financial assets during the year ended December 31, 2023. At December 31, 2023 and December 31, 2022, the Company had $81 million and $121 million of residential mortgage loans in the process of foreclosure, respectively. Included in loans held for investment at December 31, 2023 and December 31, 2022, were loans of $9 million and $101 million, respectively, to officers, directors, and their related interests and parties. There were no loans to principal shareholders at that date. Modifications to Borrowers Experiencing Financial Difficulty Effective January 1, 2023, the Company adopted ASU 2022-02- Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. For additional information on the adoption, refer to Note 1 - Description of Business, Organization and Basis of Presentation. When borrowers are experiencing financial difficulty, the Company may make certain loan modifications as part of loss mitigation strategies to maximize expected payment. Modifications in the form of principal forgiveness, an interest rate reduction, or an other-than-insignificant payment delay or a term extension that have occurred in the current reporting period to a borrower experiencing financial difficulty are disclosed along with the financial impact of the modifications. The following table summarizes the amortized cost basis of loans modified during the reporting period to borrowers experiencing financial difficulty, disaggregated by class of financing receivable and type of modification: Amortized Cost (dollars in millions) Interest Rate Reduction Term Extension Combination - Interest Rate Reduction & Term Extension Total Percent of Total Loan class Year Ended December 31, 2023 Multi-family $ 122 $ — $ — $ 122 1.17 % Commercial real estate 102 1 — 103 0.98 % One-to-four family first mortgage 3 5 6 14 0.23 % Commercial and Industrial — 19 2 21 0.08 % Other Consumer $ — $ — $ 2 2 0.08 % Total $ 227 $ 25 $ 10 $ 262 The following table describes the financial effect of the modification made to borrowers experiencing financial difficulty: Interest Rate Reduction Term Extension Weighted-average contractual interest rate From To Weighted-average Term (in years) Year Ended December 31, 2023 Multi-family 7.45 % 6.02 % Commercial real estate 8.83 % 4.56 % One-to-four family first mortgage 6.08 % 4.79 % Commercial and industrial 8.44 % 8.08 % 0.58 Other Consumer 9.09 % 4.82 % As of December 31, 2023, there were $4 million one-to-four family first mortgages that were modified for borrowers experiencing financial difficulty that received term extension and subsequently defaulted during the period and $4 million one-to-four family first mortgages that were combination modifications and subsequently defaulted during the period. The performance of loans made to borrowers experiencing financial difficulty in which modifications were made is closely monitored to understand the effectiveness of modification efforts. Loans are considered to be in payment default at 90 or more days past due. The following table depicts the performance of loans that have been modified during the reporting period: December 31, 2023 (dollars in millions) Current 30 - 89 Past Due 90+ Past Due Total Commercial real estate 1 — — 1 One-to-four family first mortgage 3 — 8 11 Commercial and industrial 3 9 1 13 Other Consumer 1 1 — 2 Total $ 8 $ 10 $ 9 $ 27 Troubled Debt Restructurings Prior to Adoption of ASU 2022-02 Prior to the adoption of ASU 2022-02, the Company accounted for certain loan modifications and restructurings as TDRs. In general, a modification or restructuring of a loan constituted a TDR if the Company granted a concession to a borrower experiencing financial difficulty. A loan modified as a TDR was generally placed on non-accrual status until the Company determined that future collection of principal and interest is reasonably assured, which requires, among other things, that the borrower demonstrate performance according to the restructured terms for a period of at least six consecutive months. In determining the Company’s allowance for credit losses on loans and leases, reasonably expected TDRs were individually evaluated and consist of criticized, classified, or maturing loans that will have a modification processed within the next three months. In an effort to proactively manage delinquent loans, the Company has selectively extended to certain borrowers concessions such as rate reductions, extension of maturity dates, and forbearance agreements. As of December 31, 2022, loans on which concessions were made with respect to rate reductions and/or extension of maturity dates amounted to $44 million.

Allowance for Credit Losses on Loans and Leases	Allowance for Credit Losses on Loans and Leases Allowance for Credit Losses on Loans and Leases The following table summarizes activity in the allowance for credit losses for the periods indicated: For the Years Ended December 31, 2023 2022 (in millions) Mortgage Other Total Mortgage Other Total Balance, beginning of period $ 290 $ 103 $ 393 $ 178 $ 21 $ 199 Adjustment for Purchased PCD Loans 13 13 21 30 51 Charge-offs (178) (45) (223) (5) (2) (7) Recoveries 15 15 4 7 11 Provision for (recovery of) credit losses on loans and leases 644 150 794 92 47 139 Balance, end of period $ 756 $ 236 $ 992 $ 290 $ 103 $ 393 As of December 31, 2023, the allowance for credit losses on loans and leases totaled $992 million, up $599 million compared to December 31, 2022. The increase in the allowance for credit losses on loans and leases was primarily driven by an increase in reserves to address weakness in the office sector, potential repricing risk in the multifamily portfolio and an increase in classified assets. Also contributing to the increase in the allowance for credit losses on loans and leases was the day 1 impact of the Signature Transaction that closed on March 20, 2023, which added $141 million to the reserve. As of December 31, 2023 and December 31, 2022, the allowance for unfunded commitments totaled $52 million and $23 million, respectively. The Company charges off loans, or portions of loans, in the period that such loans, or portions thereof, are deemed uncollectible. The collectability of individual loans is determined through an assessment of the financial condition and repayment capacity of the borrower and/or through an estimate of the fair value of any underlying collateral. For non-real estate-related consumer credits, the following past-due time periods determine when charge-offs are typically recorded: (1) closed-end credits are charged off in the quarter that the loan becomes 120 days past due; (2) open-end credits are charged off in the quarter that the loan becomes 180 days past due; and (3) both closed-end and open-end credits are typically charged off in the quarter that the credit is 60 days past the date the Company received notification that the borrower has filed for bankruptcy.

Leases [Abstract]
Leases	Leases Lessor Arrangements The Company is a lessor in the equipment finance business where it has executed direct financing leases (“lease finance receivables”). The Company produces lease finance receivables through a specialty finance subsidiary that participates in syndicated loans that are brought to them, and equipment loans and leases that are assigned to them, by a select group of nationally recognized sources, and are generally made to large corporate obligors, many of which are publicly traded, carry investment grade or near-investment grade ratings, and participate in stable industries nationwide. Lease finance receivables are carried at the aggregate of lease payments receivable plus the estimated residual value of the leased assets and any initial direct costs incurred to originate these leases, less unearned income, which is accreted to interest income over the lease term using the interest method. The standard leases are typically repayable on a level monthly basis with terms ranging from 24 to 120 months. At the end of the lease term, the lessee usually has the option to return the equipment, to renew the lease or purchase the equipment at the then fair market value (“FMV”) price. For leases with a FMV renewal/purchase option, the relevant residual value assumptions are based on the estimated value of the leased asset at the end of the lease term, including evaluation of key factors, such as, the estimated remaining useful life of the leased asset, its historical secondary market value including history of the lessee executing the FMV option, overall credit evaluation and return provisions. The Company acquires the leased asset at fair market value and provides funding to the respective lessee at acquisition cost, less any volume or trade discounts, as applicable. Therefore, there is generally no selling profit or loss to recognize or defer at inception of a lease. The residual value component of a lease financing receivable represents the estimated fair value of the leased equipment at the end of the lease term. In establishing residual value estimates, the Company may rely on industry data, historical experience, and independent appraisals and, where appropriate, information regarding product life cycle, product upgrades and competing products. Upon expiration of a lease, residual assets are remarketed, resulting in either an extension of the lease by the lessee, a lease to a new customer or purchase of the residual asset by the lessee or another party. Impairment of residual values arises if the expected fair value is less than the carrying amount. The Company assesses its net investment in lease financing receivables (including residual values) for impairment on an annual basis with any impairment losses recognized in accordance with the impairment guidance for financial instruments. As such, net investment in lease financing receivables may be reduced by an allowance for credit losses with changes recognized as provision expense. On certain lease financings, the Company obtains residual value insurance from third parties to manage and reduce the risk associated with the residual value of the leased assets. At December 31, 2023 and December 31, 2022, the carrying value of residual assets with third-party residual value insurance for at least a portion of the asset value was $280 million and $32 million, respectively. The Company uses the interest rate implicit in the lease to determine the present value of its lease financing receivables. The components of lease income were as follows: For the Years Ended December 31, (in millions) 2023 2022 2021 Interest income on lease financing (1) $ 119 $ 53 $ 53 (1) Included in Interest Income – Loans and leases in the Consolidated Statements of Income and Comprehensive Income. At December 31, 2023 and December 31, 2022, the carrying value of net investment in leases, excluding purchase accounting adjustments was $3.5 billion and $1.7 billion, respectively. The components of net investment in direct financing leases, including the carrying amount of the lease receivables, as well as the unguaranteed residual asset were as follows: (in millions) December 31, 2023 December 31, 2022 Net investment in the lease - lease payments receivable $ 3,187 $ 1,685 Net investment in the lease - unguaranteed residual assets 321 60 Total lease payments $ 3,508 $ 1,745 The following table presents the remaining maturity analysis of the undiscounted lease receivables, as well as the reconciliation to the total amount of receivables recognized in the Consolidated Statements of Condition: (in millions) December 31, 2023 2024 549 2025 602 2026 874 2027 521 2028 293 Thereafter 669 Total lease payments $ 3,508 Plus: deferred origination costs 15 Less: unearned income (258) Less: purchase accounting adjustment $ (76) Total lease finance receivables, net $ 3,189 Lessee Arrangements The Company has operating leases for corporate offices, branch locations, and certain equipment. These leases generally have terms of 20 years or less, determined based on the contractual maturity of the lease, and include periods covered by options to extend or terminate the lease when the Company is reasonably certain that it will exercise those options. For the vast majority of the Company’s leases, we are not reasonably certain we will exercise our options to renew to the end of all renewal option periods. The Company determines if an arrangement is a lease at inception. Operating leases are included in other assets and other liabilities in the Consolidated Statements of Condition. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the vast majority of the leases do not provide an implicit rate, the incremental borrowing rate (FHLB borrowing rate) is used based on the information available at commencement date in determining the present value of lease payments. The implicit rate is used when readily determinable. The operating lease ROU asset is measured at cost, which includes the initial measurement of the lease liability, prepaid rent and initial direct costs incurred by the Company, less incentives received. Variable costs such as the proportionate share of actual costs for utilities, common area maintenance, property taxes and insurance are not included in the lease liability and are recognized in the period in which they are incurred. The components of lease expense were as follows: For the Years Ended December 31, (in millions) 2023 2022 2021 Operating lease cost $ 86 $ 28 $ 27 Total lease cost $ 86 $ 28 $ 27 Supplemental cash flow information related to the leases for the following periods: (in millions) For the Years Ended December 31, 2023 2022 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 64 $ 28 Supplemental balance sheet information related to the leases for the following periods: (in millions, except lease term and discount rate) December 31, 2023 December 31, 2022 Operating Leases: Operating lease right-of-use assets (1) $ 426 $ 119 Operating lease liabilities (2) $ 446 $ 122 Weighted average remaining lease term 11.2 years 6 years Weighted average discount rate percent 4.71 % 3.85 % (1) Included in Other assets (2) Included in Other liabilities (in millions) December 31, 2023 Maturities of lease liabilities: 2024 71 2025 65 2026 58 2027 52 2028 45 Thereafter 296 Total lease payments $ 587 Less: imputed interest $ (141) Total present value of lease liabilities $ 446

Mortgage Servicing Rights

Transfers and Servicing [Abstract]
Mortgage Servicing Rights	Mortgage Servicing Rights The Company has investments in MSRs that result from the sale of loans to the secondary market for which we retain the servicing. The Company accounts for MSRs at their fair value. A primary risk associated with MSRs is the potential reduction in fair value as a result of higher than anticipated prepayments due to loan refinancing prompted, in part, by declining interest rates or government intervention. Conversely, these assets generally increase in value in a rising interest rate environment to the extent that prepayments are slower than anticipated. The Company utilizes derivatives as economic hedges to offset changes in the fair value of the MSRs resulting from the actual or anticipated changes in prepayments stemming from changing interest rate environments. There is also a risk of valuation decline due to higher than expected default rates, which we do not believe can be effectively managed using derivatives. For further information regarding the derivative instruments utilized to manage our MSR risks, see Note 15 - Derivative and Hedging Activities. Changes in the fair value of residential first mortgage MSRs were as follows: (in millions) Year Ended December 31, 2023 Balance at beginning of period $ 1,033 Additions from loans sold with servicing retained 208 Reductions from sales (51) Decrease in MSR fair value due to pay-offs, pay-downs, run-off, model changes, and other (1) (80) Changes in estimates of fair value due to interest rate risk (1) (2) 1 Fair value of MSRs at end of period $ 1,111 (1) Changes in fair value are included within net return on mortgage servicing rights (2) Represents estimated MSR value change resulting primarily from market-driven changes which we manage through the use of derivatives. The following table summarizes the hypothetical effect on the fair value of servicing rights using adverse changes of 10 percent and 20 percent to the weighted average of certain significant assumptions used in valuing these assets: December 31, 2023 Fair Value (dollars in millions) Actual 10% adverse change 20% adverse change Option adjusted spread 5.4 % $ 1,091 $ 1,072 Constant prepayment rate 7.9 % 1,073 1,040 Weighted average cost to service per loan $ 69 $ 1,100 $ 1,090 December 31, 2022 Fair Value (dollars in millions) Actual 10% adverse change 20% adverse change Option adjusted spread 5.9 % $ 1,012 $ 992 Constant prepayment rate 7.9 % 1,000 970 Weighted average cost to service per loan $ 68 $ 1,023 $ 1,013 The sensitivity calculations above are hypothetical and should not be considered to be predictive of future performance. Changes in fair value based on adverse changes in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. To isolate the effect of the specified change, the fair value shock analysis is consistent with the identified adverse change, while holding all other assumptions constant. In practice, a change in one assumption generally impacts other assumptions, which may either magnify or counteract the effect of the change. For further information on the fair value of MSRs , see Note 18 - Fair Value Measures . Contractual servicing and subservicing fees, including late fees and other ancillary income are presented below. Contractual servicing fees are included within net return on mortgage servicing rights on the Consolidated Statements of Income and Comprehensive Income. Contractual subservicing fees including late fees and other ancillary income are included within loan administration income on the Consolidated Statements of Income and Comprehensive Income. Subservicing fee income is recorded for fees earned on subserviced loans, net of third-party subservicing costs.

The Bifurcated Option Note Unit SecuritiES SM (“BONUSES units”) included in the preceding table were issued by the Company on November 4, 2002 at a public offering price of $50.00 per share. Each of the 5,500,000 BONUSES units offered consisted of a capital security issued by New York Community Capital Trust V, a trust formed by the Company, and a warrant to purchase 2.4953 shares of the common stock of the Company (for a total of approximately 14 million common shares) at an effective exercise price of $20.04 per share. Each capital security has a maturity of 49 years, with a coupon, or distribution rate, of 6.00 percent on the $50.00 per share liquidation amount. The warrants and capital securities were non-callable for five years from the date of issuance and were not called by the Company when the five-year period passed on November 4, 2007. The gross proceeds of the BONUSES units totaled $275 million and were allocated between the capital security and the warrant comprising such units in proportion to their relative values at the time of issuance.

At December 31, 2023 , this discount totaled $64 million. The other remaining trust preferred securities noted in the preceding table were formed for the purpose of issuing Company Obligated Mandatorily Redeemable Capital Securities of Subsidiary Trusts Holding Solely Junior Subordinated Debentures (collectively, the “Capital Securities”). Dividends on the Capital Securities are payable either quarterly or semi-annually and are deferrable, at the Company’s option, for up to five years.

The net deferred tax liability is included in “Other liabilities” in the Consolidated Statements of Condition at December 31, 2023 and 2022. The Company evaluates the need for a deferred tax asset valuation allowances based on a more likely than not standard. The Company’s evaluation is based on its history of reporting positive taxable income in all relevant tax jurisdictions, the length of time available to utilize the net operating loss carryforwards, and the recognition of taxable income in future periods from taxable temporary differences. At December 31, 2023 and December 31, 2022, the Company had a state deferred tax asset for net operating losses (“NOL”) of $8 million and $15 million, respectively (net of federal tax impact) which includes total state net operating loss carryforwards o f $185 million at December 31, 2023, that e xpire if unused in calendar years through 2033. In connection with our ongoing assessment of deferred taxes, we analyzed each state net operating loss separately, determined the amount of net operating loss available and estimated the amount which we expected to expire unused. Based on that assessment, we recorded a valuation allowance of $5 million at December 31, 2023 and 2022 to reduce the DTA to the amount which is more likely than not to be realized.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative and Hedging Activities	Derivative and Hedging Activities The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposure to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate and liquidity risks, primarily by managing the amount, sources, and duration of its assets and liabilities and, the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the payment of future known and uncertain cash amounts, the value of which are determined by interest rates. Derivative financial instruments are recorded at fair value in other assets and other liabilities on the Consolidated Statements of Condition. The Company's policy is to present our derivative assets and derivative liabilities on the Consolidated Statement of Condition on a gross basis, even when provisions allowing for set-off are in place. However, for derivative contracts cleared through certain central clearing parties, variation margin payments are recognized as settlements. We are exposed to non-performance risk by the counterparties to our various derivative financial instruments. A majority of our derivatives are centrally cleared through a Central Counterparty Clearing House or consist of residential mortgage interest rate lock commitments further limiting our exposure to non-performance risk. We believe that the non-performance risk inherent in our remaining derivative contracts is minimal based on credit standards and the collateral provisions of the derivative agreements. Derivatives not designated as hedging instruments. The Company maintains a derivative portfolio of interest rate swaps, foreign currency swaps, futures, swaptions and forward commitments used to manage exposure to changes in interest rates and MSR asset values and to meet the needs of customers. The Company also enters into interest rate lock commitments, which are commitments to originate mortgage loans whereby the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. Market risk on interest rate lock commitments and mortgage LHFS is managed using corresponding forward sale commitments and US Treasury futures. Changes in the fair value of derivatives not designated as hedging instruments are recognized on the Consolidated Statements of Income and Comprehensive Income. Derivatives designated as hedging instruments . The Company has designated certain interest rate swaps as cash flow hedges on overnight SOFR-based variable interest payments on federal home loan bank advances. Changes in the fair value of derivatives designated as cash flow hedges are recorded in other comprehensive income on the Consolidated Statements of Condition and reclassified into interest expense in the same period in which the hedged transaction is recognized in earnings. At December 31, 2023, the Company had $10 million (net-of-tax) of unrealized gains on derivatives classified as cash flow hedges recorded in accumulated other comprehensive loss. The Company had $52 million ( net-of-tax) of unrealized gains on derivatives classified as cash flow hedges recorded in accumulated other comprehensive loss at December 31, 2022. Derivatives that are designated in hedging relationships are assessed for effectiveness using regression analysis at inception and qualitatively thereafter, unless regression analysis is deemed necessary. All designated hedge relationships were, and are expected to be, highly effective as of December 31, 2023. Fair Value of Hedges of Interest Rate Risk The Company is exposed to changes in the fair value of certain of its fixed-rate assets due to changes in interest rates. The Company uses interest rate swaps to manage its exposure to changes in fair value on these instruments attributable to changes in the designated benchmark interest rate. Interest rate swaps designated as fair value hedges involve the payment of fixed-rate amounts to a counterparty in exchange for the Company receiving variable-rate payments over the life of the agreements without the exchange of the underlying notional amount. Such derivatives were used to hedge the changes in fair value of certain of its pools of prepayable fixed rate assets. For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in interest income. The Company has interest rate swaps with a notional amounts of $2.0 billion to hedge certain multi-family loans using the portfolio layer method. For the year ended December 31, 2023, the floating rate received related to the net settlement of these interest rate swaps was greater than the fixed rate payments. As such, interest income from loans and leases in the accompanying Consolidated Statements of Income and Comprehensive Income was increased by $24 million for the year ended December 31, 2023 and decreased by $6 million for the year ended December 31, 2022, respectively. The fair value basis adjustment on our hedged real estate loans is included in loans and leases held for investment on our Consolidated Statements of Condition. The carrying amount of our hedged loans was $6.1 billion at December 31, 2023 , of which unrealized gains of $9 million were due to the fair value hedge relationship. We have designated $2.0 billion of this portfolio of loans in a hedging relationship as of December 31, 2023 .

Cash Flow Hedges of Interest Rate Risk The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. Interest rate swaps designated as cash flow hedges involve the receipt of amounts subject to variability caused by changes in interest rates from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Changes in the fair value of derivatives designated and that qualify as cash flow hedges are initially recorded in other comprehensive income and are subsequently reclassified into earnings in the period that the hedged transaction affects earnings. Interest rate swaps with notional amounts totaling $5.5 billion and $3.8 billion as of December 31, 2023 and December 31, 2022, were designated as cash flow hedges of certain FHLB borrowings. The following table presents the effect of the Company’s cash flow derivative instruments on AOCL: For the Years Ended December 31, (in millions) 2023 2022 2021 Amount of gain (loss) recognized in AOCL $ 9 $ 88 $ 8 Amount of reclassified from AOCL to interest expense $ (65) $ (4) $ 25 Amounts reported in AOCL related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s variable-rate borrowings.

Goodwill and Intangible Assets Disclosure [Abstract]
Intangible Assets	Intangible Assets Goodwill We record goodwill in our consolidated statements of condition in connection with certain of our business combinations. Goodwill, which is tested at least annually for impairment, refers to the difference between the purchase price and the fair value of an acquired company’s assets, net of the liabilities assumed. As of December 31, 2023, the Company identified a triggering event and applied a market approach using the end of day stock price. We evaluated those conditions known and knowable by the company and how a market participant would view the control premium as confirmed by the subsequent confirming market evidence. This adjusted market capitalization was then compared to the carrying value to determine the extent of the shortfall which was calculated to be in excess of the goodwill balance. The Company’s assessment concluded that goodwill from historical transactions (2007 and prior) was fully impaired as of December 31, 2023. As a result, the Company recorded an impairment charge of the entire goodwill balance of $2.4 billion. Goodwill and related changes in the carrying amount during the year ended December 31, 2023 are as follows: (in millions) Gross Carrying Amount Balance at December 31, 2022 $ 2,426 Impairment (2,426) Balance at December 31, 2023 $ — Finite-lived Intangible Assets As a result of the Signature Transaction, the Company recorded $464 million of core deposit intangible and other intangible assets that are amortizable.

Broker-Dealer [Abstract]
Capital	Capital The Bank is subject to regulation, examination, and supervision by the OCC and the Federal Reserve (the “Regulators”). The Bank is also governed by numerous federal and state laws and regulations, including the FDIC Improvement Act of 1991, which established five categories of capital adequacy ranging from “well capitalized” to “critically undercapitalized.” Such classifications are used by the FDIC to determine various matters, including prompt corrective action and each institution’s FDIC deposit insurance premium assessments. Capital amounts and classifications are also subject to the Regulators’ qualitative judgments about the components of capital and risk weightings, among other factors. The quantitative measures established to ensure capital adequacy require that banks maintain minimum amounts and ratios of leverage capital to average assets and of common equity tier 1 capital, tier 1 capital, and total capital to risk-weighted assets (as such measures are defined in the regulations). At December 31, 2023, our capital measures continued to exceed the minimum federal requirements for a bank holding company and for a bank. The following tables sets forth our common equity tier 1, tier 1 risk-based, total risk-based, and leverage capital amounts and ratios on a consolidated basis and for the Bank on a stand-alone basis, as well as the respective minimum regulatory capital requirements, at that date: The following table presents the actual capital amounts and ratios for the Company: Risk-Based Capital December 31, 2023 Common Equity Tier 1 Tier 1 Total Leverage Capital (dollars in millions) Amount Ratio Amount Ratio Amount Ratio Amount Ratio Total capital $ 8,009 9.05 % $ 8,512 9.62 % $ 10,415 11.77 % $ 8,512 7.75 % Minimum for capital adequacy purposes 3,983 4.50 5,310 6.00 7,081 8.00 4,392 4.00 Excess $ 4,026 4.55 % $ 3,202 3.62 % $ 3,334 3.77 % $ 4,120 3.75 % December 31, 2022 Total capital $ 6,335 9.06 % $ 6,838 9.78 % $ 8,154 11.66 % $ 6,838 9.70 % Minimum for capital adequacy purposes 3,146 4.50 4,195 6.00 5,593 8.00 2,819 4.00 Excess $ 3,189 4.56 % $ 2,643 3.78 % $ 2,561 3.66 % $ 4,019 5.70 % The following table presents the actual capital amounts and ratios for the Bank: Risk-Based Capital December 31, 2023 Common Equity Tier 1 Tier 1 Total Leverage Capital (dollars in millions) Amount Ratio Amount Ratio Amount Ratio Amount Ratio Total capital $ 9,305 10.52 % $ 9,305 10.52 % $ 10,271 11.61 % $ 9,305 8.48 % Minimum for capital adequacy purposes 3,980 4.50 5,307 6.00 7,076 8.00 4,389 4.00 Excess $ 5,325 6.02 % $ 3,998 4.52 % $ 3,195 3.61 % $ 4,916 4.48 % December 31, 2022 Total capital $ 7,653 10.96 % $ 7,653 10.96 % $ 7,982 11.43 % $ 7,653 10.87 % Minimum for capital adequacy purposes 3,142 4.50 4,189 6.00 5,585 8.00 2,817 4.00 Excess $ 4,511 6.46 % $ 3,464 4.96 % $ 2,397 3.43 % $ 4,836 6.87 % At December 31, 2023, our total risk-based capital ratio exceeded the minimum requirement for capital adequacy purposes by 377 basis points and the fully phased-in capital conservation buffer by 127 basis points. The Bank also exceeded the minimum capital requirements to be categorized as “Well Capitalized.” To be categorized as well capitalized, a bank must maintain a minimum common equity tier 1 ratio of 6.50 percent; a minimum tier 1 risk-based capital ratio of 8 percent; a minimum total risk-based capital ratio of 10 percent; and a minimum leverage capital ratio of 5 percent. Preferred Stock On March 17, 2017, the Company issued 20,600,000 depositary shares, each representing a 1/40th interest in a share of the Company’s Fixed-to-Floating Rate Series A Noncumulative Perpetual Preferred Stock, par value $0.01 per share, with a liquidation preference of $1.00 per share (equivalent to $25 per depositary share). Dividends will accrue on the depositary shares at a fixed rate equal to 6.375 percent per annum until March 17, 2027, and a floating rate equal to Three-month LIBOR plus 382.1 basis points per annum beginning on March 17, 2027. Dividends will be payable in arrears on March 17, June 17, September 17, and December 17 of each year, which commenced on June 17, 2017. Treasury Stock Repurchases On October 23, 2018, the Board of Directors approved the repurchase of up to $300 million of the Company’s outstanding common stock. As of December 31, 2023, the Company has repurchased a total of 30 million shares at an average price of $9.61 or an aggregate purchase of $286 million. The Company had no repurchases during 2023. During the year ended December 31, 2022, the Company repurchased 871,710 shares, at a cost of $8 million.

Fair Value Measures

Fair Value Disclosures [Abstract]
Fair Value Measures	Fair Value Measures GAAP sets forth a definition of fair value, establishes a consistent framework for measuring fair value, and requires disclosure for each major asset and liability category measured at fair value on either a recurring or non-recurring basis. GAAP also clarifies that fair value is an “exit” price, representing the amount that would be received when selling an asset, or paid when transferring a liability, in an orderly transaction between market participants. Fair value is thus a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: • Level 1 – Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2 – Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. • Level 3 – Inputs to the valuation methodology are significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants use in pricing an asset or liability. • A financial instrument’s categorization within this valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following tables present assets and liabilities that were measured at fair value on a recurring basis as of December 31, 2023 and December 31, 2022, and that were included in the Company’s Consolidated Statements of Condition at those dates: December 31, 2023 (in millions) Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Netting Adjustments Total Fair Value Assets: Mortgage-related Debt Securities Available for Sale: GSE certificates $ — $ 1,221 $ — $ — $ 1,221 GSE CMOs — 5,162 — — 5,162 Private Label CMOs — 148 32 — 180 Total mortgage-related debt securities $ — $ 6,531 $ 32 $ — $ 6,563 Other Debt Securities Available for Sale: U.

Changes from one quarter to the next that are related to the observability of inputs for a fair value measurement may result in a reclassification from one hierarchy level to another. A description of the methods and significant assumptions utilized in estimating the fair values of securities follows: Where quoted prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities include highly liquid government securities and exchange-traded securities. If quoted market prices are not available for a specific security, then fair values are estimated by using pricing models. These pricing models primarily use market-based or independently sourced market parameters as inputs, including, but not limited to, yield curves, interest rates, equity or debt prices, and credit spreads. In addition to observable market information, models incorporate transaction details such as maturity and cash flow assumptions. Securities valued in this manner would generally be classified within Level 2 of the valuation hierarchy, and primarily include such instruments as mortgage-related and corporate debt securities. Periodically, the Company uses fair values supplied by independent pricing services to corroborate the fair values derived from the pricing models. In addition, the Company reviews the fair values supplied by independent pricing services, as well as their underlying pricing methodologies, for reasonableness. The Company challenges pricing service valuations that appear to be unusual or unexpected. While the Company believes its valuation methods are appropriate, and consistent with those of other market participants, the use of different methodologies or assumptions to determine the fair values of certain financial instruments could result in different estimates of fair values at a reporting date.

(2) Rate lock commitments are reported on a fallout-adjusted basis. Transfers out of Level 3 represent the settlement value of the commitments that are transferred to LHFS, which are classified as Level 2 assets.

Assets Measured at Fair Value on a Non-Recurring Basis Certain assets are measured at fair value on a non-recurring basis. Such instruments are subject to fair value adjustments under certain circumstances (e.g., when there is evidence of impairment). The following tables present assets that were measured at fair value on a non-recurring basis as of December 31, 2023 and December 31, 2022, and that were included in the Company’s Consolidated Statements of Condition at those dates: Fair Value Measurements at December 31, 2023 Using (in millions) Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Fair Value Certain impaired loans (1) $ — $ — $ 197 $ 197 Other assets (2) — — 50 50 Total $ — $ — $ 247 $ 247 (1) Represents the fair value of impaired loans, based on the value of the collateral.

These equity securities are classified as Level 3 due to the infrequency of the observable prices and/or the restrictions on the shares. The fair values of collateral-dependent impaired loans are determined using various valuation techniques, including consideration of appraised values and other pertinent real estate and other market data. Other Fair Value Disclosures For the disclosure of fair value information about the Company’s on- and off-balance sheet financial instruments, when available, quoted market prices are used as the measure of fair value. In cases where quoted market prices are not available, fair values are based on present-value estimates or other valuation techniques. Such fair values are significantly affected by the assumptions used, the timing of future cash flows, and the discount rate. Because assumptions are inherently subjective in nature, estimated fair values cannot be substantiated by comparison to independent market quotes. Furthermore, in many cases, the estimated fair values provided would not necessarily be realized in an immediate sale or settlement of such instruments. The following tables summarize the carrying values, estimated fair values, and fair value measurement levels of financial instruments that were not carried at fair value on the Company’s Consolidated Statements of Condition at December 31, 2023 and December 31, 2022: December 31, 2023 Fair Value Measurement Using (in millions) Carrying Value Estimated Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Financial Assets: Cash and cash equivalents $ 11,475 $ 11,475 $ 11,475 $ — $ — FHLB and FRB stock (1) $ 1,392 $ 1,392 $ — $ 1,392 $ — Loans and leases held for investment, net $ 83,627 $ 79,333 $ — $ — $ 79,333 Financial Liabilities: Deposits $ 81,526 $ 81,247 $ 59,972 (2) $ 21,275 (3) $ — Borrowed funds $ 21,267 $ 21,082 $ — $ 21,082 $ — (1) Carrying value and estimated fair value are at cost.

(2) Interest-bearing checking and money market accounts, savings accounts, and non-interest-bearing accounts. (3) Certificates of deposit. The methods and significant assumptions used to estimate fair values for the Company’s financial instruments follow: Cash and Cash Equivalents Cash and cash equivalents include cash and due from banks and federal funds sold. The estimated fair values of cash and cash equivalents are assumed to equal their carrying values, as these financial instruments are either due on demand or have short-term maturities. Securities If quoted market prices are not available for a specific security, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics, or discounted cash flows. These pricing models primarily use market-based or independently sourced market parameters as inputs, including, but not limited to, yield curves, interest rates, equity or debt prices, and credit spreads. In addition to observable market information, pricing models also incorporate transaction details such as maturities and cash flow assumptions. Federal Home Loan Bank Stock Ownership in equity securities of the FHLB is generally restricted and there is no established liquid market for their resale. The carrying amount approximates the fair value. Loans and leases The Company discloses the fair value of loans measured at amortized cost using an exit price notion. The Company determined the fair value on substantially all of its loans for disclosure purposes, on an individual loan basis. The discount rates reflect current market rates for loans with similar terms to borrowers having similar credit quality on an exit price basis. For those loans where a discounted cash flow technique was not considered reliable, the Company used a quoted market price for each individual loan. MSRs The significant unobservable inputs used in the fair value measurement of the MSRs are option adjusted spreads, prepayment rates and cost to service. Significant increases (decreases) in all three assumptions in isolation result in a significantly lower (higher) fair value measurement. Weighted average life (in years) is used to determine the change in fair value of MSRs. For December 31, 2023, the weighted average life (in years) for the entire portfolio was 6.83. Rate lock commitments The significant unobservable input used in the fair value measurement of the rate lock commitments is the pull through rate. The pull through rate is a statistical analysis of our actual rate lock fallout history to determine the sensitivity of the residential mortgage loan pipeline compared to interest rate changes and other deterministic values. New market prices are applied based on updated loan characteristics and new fallout ratios (i.e. the inverse of the pull through rate) are applied accordingly. Significant increases (decreases) in the pull through rate in isolation result in a significantly higher (lower) fair value measurement. Deposits The fair values of deposit liabilities with no stated maturity (i.e., interest-bearing checking and money market accounts, savings accounts, and non-interest-bearing accounts) are equal to the carrying amounts payable on demand. The fair values of CDs represent contractual cash flows, discounted using interest rates currently offered on deposits with similar characteristics and remaining maturities. These estimated fair values do not include the intangible value of core deposit relationships, which comprise a portion of the Company’s deposit base. Borrowed Funds The estimated fair value of borrowed funds is based either on bid quotations received from securities dealers or the discounted value of contractual cash flows with interest rates currently in effect for borrowed funds with similar maturities and structures. Off-Balance Sheet Financial Instruments The fair values of commitments to extend credit and unadvanced lines of credit are estimated based on an analysis of the interest rates and fees currently charged to enter into similar transactions, considering the remaining terms of the commitments and the creditworthiness of the potential borrowers. The estimated fair values of such off-balance sheet financial instruments were insignificant at December 31, 2023 and December 31, 2022. Fair Value Option We elected the fair value option for certain items as discussed throughout the Notes to the Consolidated Financial Statements to more closely align the accounting method with the underlying economic exposure. Interest income on LHFS is accrued on the principal outstanding primarily using the "simple-interest" method. The following table reflects the change in fair value included in earnings of financial instruments for which the fair value option has been elected: For the Years Ended December 31, (dollars in millions) 2023 2022 Assets Loans held-for-sale Net gain on loan sales $ 43 $ 8 The following table reflects the difference between the aggregate fair value and aggregate remaining contractual principal balance outstanding for assets and liabilities for which the fair value option has been elected: December 31, 2023 (dollars in millions) Unpaid Principal Balance Fair Value Fair Value Over / (Under) UPB Assets: Nonaccrual loans: Loans held-for-sale $ 2 $ 2 $ — Total non-accrual loans $ 2 $ 2 $ — Other performing loans: Loans held-for-sale $ 869 $ 894 $ 25 Total other performing loans $ 869 $ 894 $ 25 Total loans: Loans held-for-sale $ 871 $ 896 $ 25 Total loans $ 871 $ 896 $ 25 December 31, 2022 (dollars in millions) Unpaid Principal Balance Fair Value Fair Value Over / (Under) UPB Assets: Other performing loans: Loans held-for-sale $ 1,095 $ 1,115 $ 20 Total other performing loans $ 1,095 $ 1,115 $ 20 Total loans: Loans held-for-sale $ 1,095 $ 1,115 $ 20 Total loans $ 1,095 $ 1,115 $ 20

Retirement Benefits [Abstract]
Employee Benefits	Employee Benefits Retirement Plan The New York Community Bancorp, Inc. Retirement Plan (the “Retirement Plan”) covers substantially all employees who had attained minimum age, service, and employment status requirements prior to the date when the individual plans were frozen by the banks of origin. Once frozen, the individual plans ceased to accrue additional benefits, service, and compensation factors, and became closed to employees who would otherwise have met eligibility requirements after the “freeze” date. The following table sets forth certain information regarding the Retirement Plan as of the dates indicated: December 31, (in millions) 2023 2022 Change in Benefit Obligation: Benefit obligation at beginning of year $ 116 $ 158 Interest cost 5 4 Actuarial gain 2 (38) Annuity payments (7) (7) Settlements (1) (1) Benefit obligation at end of year $ 115 $ 116 Change in Plan Assets: Fair value of assets at beginning of year $ 228 $ 283 Actual return (loss) on plan assets 33 (47) Annuity payments (7) (7) Settlements (1) (1) Fair value of assets at end of year $ 253 $ 228 Funded status (included in “Other assets”) $ 138 $ 112 Changes recognized in other comprehensive income for the year ended December 31: Amortization of actuarial loss $ (7) $ (2) Net actuarial (gain) loss arising during the year (18) 26 Total recognized in other comprehensive income for the year (pre-tax) $ (25) $ 24 Accumulated other comprehensive loss (pre-tax) not yet recognized in net periodic benefit cost at December 31: Actuarial loss, net $ 41 $ 66 Total accumulated other comprehensive loss (pre-tax) $ 41 $ 66 In 2024 $3 million of unrecognized net actuarial loss for the Retirement Plan will be amortized from AOCL into net periodic benefit cost, respectively. The comparable amount recognized as net actuarial loss for the Retirement Plan in 2023 was $7 million and no prior service cost was amortized in 2022. The discount rates used to determine the benefit obligation at December 31, 2023 and 2022 were 4.7 percent and 4.9 percent, respectively. The discount rate reflects rates at which the benefit obligation could be effectively settled. To determine this rate, the Company considers rates of return on high-quality fixed-income investments that are currently available and are expected to be available during the period until the pension benefits are paid. The expected future payments are discounted based on a portfolio of high-quality rated bonds (AA or better) for which the Company relies on the Financial Times Stock Exchange (“FTSE”) Pension Liability Index that is published as of the measurement date. The components of net periodic pension (credit) expense were as follows for the years indicated: Years Ended December 31, (in millions) 2023 2022 2021 Components of net periodic pension expense (credit): Interest cost $ 5 $ 4 $ 4 Expected return on plan assets (14) (16) (16) Amortization of net actuarial loss 7 2 7 Net periodic pension credit $ (2) $ (10) $ (5) The following table indicates the weighted average assumptions used in determining the net periodic benefit cost for the years indicated: Years Ended December 31, 2023 2022 2021 Discount rate 4.9 % 2.6 % 2.2 % Expected rate of return on plan assets 6.3 6.0 6.3 The primary long-term objective for the Plan is to maintain assets at a level that will sufficiently cover future beneficiary obligations. A secondary long-term objective is to achieve long-term growth in assets. The Plan will be structured to include a volatility reducing component (the fixed income commitment) and a growth component (the equity commitment). To achieve the Companies (in this context, the "Plan Sponsor") long-term investment objectives, the Trustee will invest the assets of the Plan in a diversified combination of asset classes, investment strategies, and pooled vehicles. The asset allocation guidelines in the table below reflect the plan sponsor’s risk tolerance and long-term objectives for the Plan. These parameters will be reviewed on a regular basis and subject to change following discussions between the plan sponsor and the Trustee. Initially, the following asset allocation targets and ranges will guide the Trustee in structuring the overall allocation in the Plan’s investment portfolio. The plan sponsor or the Trustee may amend these allocations to reflect the most appropriate standards consistent with changing circumstances. Any such fundamental amendments in strategy will be discussed between the plan sponsor and the Trustee prior to implementation. Based on the above considerations, the following asset allocation ranges will be implemented: Asset Allocation Parameters by Asset Class Equity Minimum Target Maximum U.S. Large-Cap 27% U.S. Mid-Cap 7% U.S. Small-Cap 7% Non-U.S. 14% Total - Equity 45% 55% 65% Total - Fixed Income/Cash Equivalents 35% 45% 55% The parameters for each asset class provide the Trustee with the latitude for managing the Plan within a minimum and maximum range. The Trustee will have full discretion to buy, sell, invest and reinvest in these asset segments based on these guidelines which includes allowing the underlying investments to fluctuate within the stated policy ranges. The Plan will maintain a cash equivalents component (not to exceed 3 percent under normal circumstances) within the fixed income allocation for liquidity purposes. The Trustee will monitor the actual asset segment exposures of the Plan on a regular basis and, periodically, may adjust the asset allocation within the ranges set forth above as it deems appropriate. Periodic reallocation of assets will be based on the Trustee’s perception of the changing risk/return opportunities of the respective asset classes. The following table presents information about the fair value measurements of the investments held by the Retirement Plan as of December 31, 2023 : (in millions) Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Equity: Large-cap value (1) $ 12 $ 12 $ — $ — Large-cap growth (2) 22 22 — — Large-cap core (3) 17 17 — — Mid-cap core (4) 15 15 — — Small-cap core (5) 16 16 — — International growth (6) 18 18 — — International value (7) 10 10 — — Fixed Income Funds: Intermediate - Core Plus (8) 98 98 — — Equity Securities: Company common stock 31 31 — — Common/Collective Trusts-Equity: Large cap value (9) 13 — 13 — Cash Equivalents: Money market (10) 1 1 — $ 253 $ 240 $ 13 $ — (1) This category consists of a mutual fund holding 100-160 stocks, designed to track and outperform the Russell 1000 Value Index. (2) This category consists of two mutual funds which invest primarily in large-cap U.S. - based growth companies, one concentrating on long-term capital growth, the other in long-term capital appreciation and current income. (3) This category contains stocks of the S&P 500 Index. The stocks are maintained in approximately the same weightings as the index. (4) This category contains stocks of the CRSP U.S. Mid Cap Index, a broadly diversified index of stocks of medium-size U.S. companies. The stocks are maintained. (5) This category seeks long-term capital appreciation through investment primarily in common stock of small-capitalization companies, with similar risk levels and characteristics to the Russell 2000 Index. (6) This category consists of investments with long-term growth potential located primarily in Europe, the Pacific Basin, and other developed and emerging markets. (7) This category invests primarily in medium to large well-established non-US companies. Under normal circumstances, at least 80 percent of total assets will be invested in equity securities, including common stocks, preferred stocks, and convertible securities. (8) This category currently includes equal investments in four mutual funds, seeking to outperform the Bloomberg Barclays U.S. Aggregate Bond Index. Two of the funds hold at least 80 percent in investment grade fixed-income securities while one other holds at least 65 percent; the fourth fund targets investments of 50 percent or more in mortgage-backed securities guaranteed by the US government and its agencies. (9) This category contains large-cap stocks with above-average yield. The portfolio typically holds between 60 and 70 stocks. (10) This category consists of a money market fund and is used for liquidity purposes. Current Asset Allocation The asset allocations for the Retirement Plan were as follows: December 31, 2023 2022 Equity securities 61 % 60 % Debt securities 39 % 38 % Cash equivalents — % 2 % Total 100 % 100 % Determination of Long-Term Rate of Return The long-term rate of return on Retirement Plan assets assumption was based on historical returns earned by equities and fixed income securities, and adjusted to reflect expectations of future returns as applied to the Retirement Plan’s target allocation of asset classes. Equities and fixed income securities were assumed to earn long-term rates of return in the ranges of 6 percent to 8 percent and 3 percent to 5 percent, respectively, with an assumed long-term inflation rate of 2.5 percent reflected within these ranges. When these overall return expectations are applied to the Retirement Plan’s target allocations, the result is an expected rate of return of 5 percent to 7 percent. Expected Contributions The Company does not expect to contribute to the Retirement Plan in 2023. Expected Future Annuity Payments The following annuity payments, which reflect expected future service, as appropriate, are expected to be paid by the Retirement Plan during the years indicated: (in millions) 2024 $ 8 2025 8 2026 8 2027 8 2028 8 2029 and thereafter 43 Total $ 83 Qualified Savings Plan (401(k) Plan) The Company maintains a defined contribution qualified savings plan in the form of a 401(k) plan in which all salaried employees are able to participate after one month of service and having attained age 21. The Company instituted a safe harbor matching contribution program during the year ended December 31, 2020, and accordingly, the Company matches a portion of employee 401(k) plan contributions. Such expense totaled $21 million and $7 million for the year ended December 31, 2023 and 2022 , respectively. Flagstar also maintains a defined contribution qualified savings plan in the form of a 401(k) plan in which certain employees are able to participate. Post-Retirement Health and Welfare Benefits The Company offers certain post-retirement benefits, including medical, dental, and life insurance (the “Health & Welfare Plan”) to retired employees, depending on age and years of service at the time of retirement. The costs of such benefits are accrued during the years that an employee renders the necessary service. The Health & Welfare Plan is an unfunded plan and is not expected to hold assets for investment at any time. Any contributions made to the Health & Welfare Plan are used to immediately pay plan premiums and claims as they come due. The following table sets forth certain information regarding the Health & Welfare Plan as of the dates indicated: December 31, (in millions) 2023 2022 Change in benefit obligation: Benefit obligation at beginning of year $ 7 $ 10 Interest cost 1 — Actuarial gain 1 (2) Premiums and claims paid (1) (1) Benefit obligation at end of year $ 8 $ 7 Change in plan assets: Fair value of assets at beginning of year $ — $ — Employer contribution 1 1 Premiums and claims paid (1) (1) Fair value of assets at end of year $ — $ — Funded status (included in “Other liabilities”) $ (8) $ (7) Changes recognized in other comprehensive income for the year ended December 31: Amortization of prior service cost — Amortization of actuarial gain — Net actuarial (gain) loss arising during the year 1 (2) Total recognized in other comprehensive income for the year (pre-tax) $ 1 $ (2) Accumulated other comprehensive (gain) loss (pre-tax) not yet recognized in net periodic benefit cost at December 31: Prior service cost — Actuarial (gain) loss, net (1) (2) Total accumulated other comprehensive income (pre-tax) $ (1) $ (2) The discount rates used in the preceding table were 4.6 percent at December 31, 2023 and 4.8 percent at December 31, 2022. The estimated net actuarial loss and the prior service liability that will be amortized from AOCL into net periodic benefit cost in 2024 are less than $1 million, respectively. The net periodic benefit costs and all components thereof for the years-ended December 31, 2023 and 2022 were less than $1 million. The following table presents the weighted average assumptions used in determining the net periodic benefit cost for the years indicated: Years Ended December 31, 2023 2022 2021 Discount rate 4.8% 2.3% 2.0% Current medical trend rate 6.5 6.5 6.5 Ultimate trend rate 5.0 5.0 5.0 Year when ultimate trend rate will be reached 2029 2028 2027 Expected Contributions The Company expects to contribute $1 million to the Health & Welfare Plan to pay premiums and claims in the fiscal year ending December 31, 2023 .

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	The following is a description of the significant accounting and reporting policies that the Company and its subsidiaries follow in preparing and presenting their consolidated financial statements, which conform to U.S. generally accepted accounting principles and to general practices within the banking industry. The preparation of financial statements in conformity with GAAP requires the Company to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Estimates are used in connection with the determination of the allowance for credit losses, mortgage servicing rights, the Flagstar acquisition and the Signature Transaction. As a member of the FHLB-NY, the Company is required to hold shares of FHLB-NY stock, which is carried at cost. In addition, in connection with the Flagstar acquisition, the Company also holds shares of FHLB-Indianapolis stock, which is carried at cost. The Company’s holding requirement varies based on certain factors, including its outstanding borrowings from the FHLB-NY and FHLB-Indianapolis.
Consolidation	The accompanying consolidated financial statements include the accounts of the Company and other entities in which the Company has a controlling financial interest. All inter-company accounts and transactions are eliminated in consolidation. The Company currently has certain unconsolidated subsidiaries in the form of wholly-owned statutory business trusts, which were formed to issue guaranteed capital securities.
Recently Adopted Accounting Standards	Prior to the adoption of ASU 2022-02, the Company accounted for certain loan modifications and restructurings as TDRs. In general, a modification or restructuring of a loan constituted a TDR if the Company granted a concession to a borrower experiencing financial difficulty.
Cash and Cash Equivalents and Restricted Cash	For cash flow reporting purposes, cash and cash equivalents include cash on hand, amounts due from banks, and money market investments, which include federal funds sold and reverse repurchase agreements, if any. At December 31, 2023 and 2022, the Company’s cash and cash equivalents totaled $11.5 billion and $2.0 billion, respectively. Included in cash and cash equivalents at those dates were $10.7 billion and $837 million , respectively, of interest-bearing deposits in other financial institutions, primarily consisting of balances due from the FRB-NY. There were no reverse repurchase agreements outstanding as of December 31, 2023 and $793 million of reverse repurchase agreements were outstanding at December 31, 2022. There were no federal funds sold outstanding at December 31, 2023 or December 31, 2022. Restricted cash totaled $134 million and $50 million at December 31, 2023 and December 31, 2022, respectively and includes cash that the Bank pledges as maintenance margin on centrally cleared derivatives and is included in other assets on the Consolidated Statements of Condition.
Debt Securities and Equity Investments with Readily Determinable Fair Values	The securities portfolio primarily consists of mortgage-related securities and, to a lesser extent, debt and equity securities. Securities that are classified as “available for sale” are carried at their estimated fair value, with any unrealized gains or losses, net of taxes, reported as accumulated other comprehensive income or loss in stockholders’ equity. Securities that the Company has the intent and ability to hold to maturity are classified as “held to maturity” and carried at amortized cost. The fair values of our securities—and particularly our fixed-rate securities—are affected by changes in market interest rates and credit spreads. In general, as interest rates rise and/or credit spreads widen, the fair value of fixed-rate securities will decline. As interest rates fall and/or credit spreads tighten, the fair value of fixed-rate securities will rise. The Company evaluates available-for-sale debt securities in unrealized loss positions at least quarterly to determine if an allowance for credit losses is required. Based on an evaluation of available information about past events, current conditions, and reasonable and supportable forecasts that are relevant to collectability, the Company has concluded that it expects to receive all contractual cash flows from each security held in its available-for-sale securities portfolio. The Company first assesses whether (i) it intends to sell, or (ii) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. If either of these criteria is met, any previously recognized allowances are charged off and the security’s amortized cost basis is written down to fair value through income. If neither of the aforementioned criteria are met, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Management has made the accounting policy election to exclude accrued interest receivable on available-for-sale securities from the estimate of credit losses. Available-for-sale debt securities are placed on non-accrual status when the Company no longer expects to receive all contractual amounts due, which is generally at 90 days past due. Accrued interest receivable is reversed against interest income when a security is placed on non-accrual status. Equity investments with readily determinable fair values are measured at fair value with changes in fair value recognized in net income.
Loans Held-for-Sale	The Company classifies loans as LHFS when we originate or purchase loans that we intend to sell. We have elected the fair value option for the majority of our LHFS. The Company estimates the fair value of mortgage loans based on quoted market prices for securities backed by similar types of loans, where available, or by discounting estimated cash flows using observable inputs inclusive of interest rates, prepayment speeds and loss assumptions for similar collateral. Changes in fair value are recorded to other noninterest income on the Consolidated Statements of Income and Comprehensive Income. LHFS that are recorded at the lower of cost or fair value may be carried at fair value on a nonrecurring basis when the fair value is less than cost.
Loans	Loans that are transferred into the LHFS portfolio from the LHFI portfolio, due to a change in intent, are recorded at the lower of cost or fair value. Gains or losses recognized upon the sale of loans are determined using the specific identification method. Loans Held for Investment Loans and leases, net, are carried at unpaid principal balances, including unearned discounts, purchase accounting (i.e., acquisition-date fair value) adjustments, net deferred loan origination costs or fees, and the allowance for credit losses on loans and leases. The Company recognizes interest income on loans using the interest method over the life of the loan. Accordingly, the Company defers certain loan origination and commitment fees, and certain loan origination costs, and amortizes the net fee or cost as an adjustment to the loan yield over the term of the related loan. When a loan is sold or repaid, the remaining net unamortized fee or cost is recognized in interest income. Prepayment income on loans is recorded in interest income and only when cash is received. Accordingly, there are no assumptions involved in the recognition of prepayment income. Two factors are considered in determining the amount of prepayment income: the prepayment penalty percentage set forth in the loan documents, and the principal balance of the loan at the time of prepayment. The volume of loans prepaying may vary from one period to another, often in connection with actual or perceived changes in the direction of market interest rates. When interest rates are declining, rising precipitously, or perceived to be on the verge of rising, prepayment income may increase as more borrowers opt to refinance and lock in current rates prior to further increases taking place. A loan generally is classified as a “non-accrual” loan when it is 90 days or more past due or when it is deemed to be impaired because the Company no longer expects to collect all amounts due according to the contractual terms of the loan agreement. When a loan is placed on non-accrual status, management ceases the accrual of interest owed, and previously accrued interest is charged against interest income. A loan is generally returned to accrual status when the loan is current and management has reasonable assurance that the loan will be fully collectible. Interest income on non-accrual loans is recorded when received in cash. Loans with Government Guarantees The Company originates government guaranteed loans which are pooled and sold as Ginnie Mae MBS. Pursuant to Ginnie Mae servicing guidelines, the Company has the unilateral right to repurchase loans securitized in Ginnie Mae pools that are due, but unpaid, for three consecutive months. As a result, once the delinquency criteria have been met, and regardless of whether the repurchase option has been exercised, the Company accounts for the loans as if they had been repurchased. The Company recognizes the loans and corresponding liability as loans with government guarantees and loans with government guarantees repurchase options, respectively, in the Consolidated Statements of Condition. If the loan is repurchased, the liability is cash settled and the loan with government guarantee remains. Once repurchased, the Company works to cure the outstanding loans such that they are re-eligible for sale or may begin foreclosure and recover losses through a claims process with the government agency, as an approved lender.
Allowance for Credit Losses on Loans and Leases	The allowance for credit losses on loans and leases is deducted from the amortized cost basis of a financial asset or a group of financial assets so that the balance sheet reflects the net amount the Company expects to collect. Amortized cost is the unpaid loan balance, net of deferred fees and expenses, and includes negative escrow. Subsequent changes (favorable and unfavorable) in expected credit losses are recognized immediately in net income as a credit loss expense or a reversal of credit loss expense. Management estimates the allowance by projecting and multiplying together the probability-of-default, loss- given-default and exposure-at-default depending on economic parameters for each month of the remaining contractual term, as well as credit ratings for certain loans within the commercial and industrial portfolio. The Company loss drivers for certain loans in the commercial and industrial portfolio are derived using leverages economic projections including property market and prepayment forecasts from established independent third parties, as well as credit ratings for certain loans within the commercial and industrial portfolio, to inform its loss drivers in the forecast. The Company estimates the exposure-at-default using prepayment models which forecasts prepayments over the life of the loans and leases. The economic forecast and the related economic parameters are developed using available information relating to past events, current conditions, multiple economic forecasts scenarios, including related weightings, over the reasonable and supportable forecast period and macroeconomic assumptions. The economic forecast scenarios and related economic parameters are sourced from independent third parties. The economic forecast reasonable and supportable period is 24 months, and afterwards the Company reverts to a historical average loss rate on a straight-line basis over a 12-month period. Historical credit loss experience over the historical loss observation period provides the basis for the estimation of expected credit losses, with qualitative factor adjustments made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, current collateral valuations, delinquency levels and terms, as well as for changes in environmental conditions, such as changes in legislation, regulation, policies, administrative practices or other relevant factors. Expected credit losses are estimated over the contractual term of the loans, adjusted for forecasted prepayments when appropriate. The contractual term excludes potential extensions or renewals. The methodology used in the estimation of the allowance for credit losses on loan and leases, which is performed at least quarterly, is designed to be dynamic and responsive to changes in portfolio credit quality and forecasted economic conditions. Each quarter the Company reassesses the appropriateness of the economic forecasting period, the reversion period and historical mean at the portfolio segment level, considering any required adjustments for differences in underwriting standards, portfolio mix, and other relevant data shifts over time. The allowance for credit losses on loans and leases is measured on a collective (pool) basis when similar risk characteristics exist. The portfolio segment represents the level at which a systematic methodology is applied to estimate credit losses. Management believes the products within each of the entity’s portfolio segments exhibit similar risk characteristics. The Company leverages economic projections including property market and prepayment forecasts from established independent third parties, as well as credit ratings for certain loans within the commercial and industrial portfolio, to inform its loss drivers in the forecast. Loans that do not share risk characteristics are evaluated on an individual basis. These include loans that are in nonaccrual status with balances above management determined materiality thresholds depending on loan class and also loans that are designated as TDR or “reasonably expected TDR” (criticized, classified, or maturing loans that will have a modification processed within the next three months). If a loan is determined to be collateral dependent, or meets the criteria to apply the collateral dependent practical expedient, expected credit losses are determined based on the fair value of the collateral at the reporting date, less costs to sell as appropriate. The Company maintains an allowance for credit losses on off-balance sheet credit exposures. At December 31, 2023 and December 31, 2022, the allowance for credit losses on off-balance sheet exposures was $52 million and $23 million, respectively. 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 is adjusted as a provision for credit losses 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 their estimated life. The Company examined historical CCF trends to estimate utilization rates, and chose an appropriate mean CCF based on both management judgment and quantitative analysis. Quantitative analysis involved examination of CCFs over a range of fund-up windows (between 12 and 36 months) and comparison of the mean CCF for each fund-up window with management judgment determining whether the highest mean CCF across fund-up windows made business sense. The Company applies the same standards and estimated loss rates to the credit exposures as to the related class of loans. When applying this critical accounting estimate, we incorporate several inputs and judgments that may be influenced by changes period to period. These include, but are not limited to changes in the economic environment and forecasts, changes in the credit profile and characteristics of the loan portfolio, and changes in prepayment assumptions which will result in provisions to or recoveries from the balance of the allowance for credit losses. While changes to the economic environment forecasts and portfolio characteristics will change from period to period, portfolio prepayments are an integral assumption in estimating the allowance for credit losses on our commercial real estate (multi-family, CRE and ADC) portfolio which comprises 60 percent of the loan portfolio at December 31, 2023. Portfolio prepayments are subject to estimation uncertainty and changes in this assumption could have a material impact to our estimation process. Prepayment assumptions are sensitive to interest rates and existing loan terms and determine the weighted average life of the commercial mortgage loan portfolio. Excluding other factors, as the weighted average life of the portfolio increases or decreases, so will the required amount of the allowance for credit losses on commercial real estate.
Goodwill	The Company evaluates goodwill for impairment at least annually or when triggering events are identified. We utilize a market approach to determine the fair value of our single reporting unit, which considers how a market participant would view a control premium, complemented by an income approach if deemed necessary. The resulting value is then compared to our book value and any shortfalls would be recorded as an impairment.
Mortgage Servicing Rights	The Company purchases and originates mortgage loans for sale to the secondary market and sell the loans on either a servicing-retained or servicing-released basis. If the Company retains the right to service the loan, an MSR is created at the time of sale which is recorded at fair value. The Company uses an internal valuation model that utilizes an option-adjusted spread, constant prepayment speeds, costs to service and other assumptions to determine the fair value of MSRs.
Premises and Equipment, Net	Premises, furniture, fixtures, and equipment are carried at cost, less the accumulated depreciation computed on a straight-line basis over the estimated useful lives of the respective assets (generally 20 years for premises and three
Variable Interest Entities	An entity that has a controlling financial interest in a VIE is referred to as the primary beneficiary and consolidates the VIE. An entity is deemed to have a controlling financial interest and is the primary beneficiary of a VIE if it has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE.
Repossessed Assets	Repossessed assets consist of any property or other assets acquired through, or in lieu of, foreclosure are sold or rented, and are recorded at fair value, less the estimated selling costs, at the date of acquisition. Following foreclosure, management periodically performs a valuation of the asset, and the assets are carried at the lower of the carrying amount or fair value, less the estimated selling costs. Expenses and revenues from operations and changes in valuation, if any, are included in “General and administrative expense” in the Consolidated Statements of Income and Comprehensive Income.
OREO	Repossessed assets consist of any property or other assets acquired through, or in lieu of, foreclosure are sold or rented, and are recorded at fair value, less the estimated selling costs, at the date of acquisition. Following foreclosure, management periodically performs a valuation of the asset, and the assets are carried at the lower of the carrying amount or fair value, less the estimated selling costs. Expenses and revenues from operations and changes in valuation, if any, are included in “General and administrative expense” in the Consolidated Statements of Income and Comprehensive Income.
Servicing Fee Income	Servicing fee income, late fees and ancillary fees received on loans for which the Company owns the MSR are included in net return on mortgage servicing rights on the Consolidated Statements of Income and Comprehensive Income. The fees are based on the outstanding principal and are recorded as income when earned. Subservicing fees, which are included in loan administration income on the Consolidated Statements of Income and Comprehensive Income, are based on a contractual monthly amount per loan including late fees and other ancillary income.
Income Taxes	Income tax expense consists of income taxes that are currently payable and deferred income taxes. Deferred income tax expense is determined by recognizing deferred tax assets and liabilities for future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates that are expected to apply to taxable income in years in which those temporary differences are expected to be recovered or settled. The Company assesses the deferred tax assets and establishes a valuation allowance when realization of a deferred asset is not considered to be “more likely than not.” The Company considers its expectation of future taxable income in evaluating the need for a valuation allowance.
Derivative Instruments and Hedging Activities	The Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. The Company utilizes derivative instruments to manage the fair value changes in our MSRs, interest rate lock commitments and LHFS portfolio which are exposed to price and interest rate risk; facilitate asset/liability management; minimize the variability of future cash flows on long-term debt; and to meet the needs of our customers. All derivatives are recognized on the Consolidated Statements of Condition as other assets and liabilities, as applicable, at their estimated fair value. The Company uses interest rate swaps, swaptions, futures and forward loan sale commitments to mitigate the impact of fluctuations in interest rates and interest rate volatility on the fair value of the MSRs. Changes in their fair value are reflected in current period earnings under the net return on mortgage servicing asset. These derivatives are valued based on quoted prices for similar assets in an active market with inputs that are observable. The Company also enters into various derivative agreements with customers and correspondents in the form of interest rate lock commitments and forward purchase contracts which are commitments to originate or purchase mortgage loans whereby the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. The derivatives are valued using internal models that utilize market interest rates and other unobservable inputs. Changes in the fair value of these commitments due to fluctuations in interest rates are economically hedged through the use of forward loan sale commitments of MBS. The gains and losses arising from this derivative activity are reflected in current period earnings under the net gain on loan sales.
Representation and Warranty Reserve	When the Company sells mortgage loans into the secondary mortgage market, it makes customary representations and warranties to the purchasers about various characteristics of each loan. Upon the sale of a loan, the Company recognizes a liability for that guarantee at its fair value as a reduction of our net gain on loan sales. Subsequent to the sale, the liability is re-measured at fair value on an ongoing basis based upon an estimate of probable future losses.
Stock-based Compensation	Under the New York Community Bancorp, Inc. 2020 Omnibus Incentive Plan (the “2020 Incentive Plan”), which was approved by the Company’s shareholders at its Annual Meeting on June 3, 2020, shares are available for grant as restricted stock or other forms of related rights. At December 31, 2023, the Company had 16,143,893
Earnings per Common Share (Basic and Diluted)	Basic EPS is computed by dividing the net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted EPS is computed using the same method as basic EPS, however, the computation reflects the potential dilution that would occur if outstanding in-the-money stock options were exercised and converted into common stock. Unvested stock-based compensation awards containing non-forfeitable rights to dividends paid on the Company’s common stock are considered participating securities, and therefore are included in the two-class method for calculating EPS. Under the two-class method, all earnings (distributed and undistributed) are allocated to common shares and participating securities based on their respective rights to receive dividends on the common stock. The Company grants restricted stock to certain employees under its stock-based compensation plan. Recipients receive cash dividends during the vesting periods of
Lessee Arrangements	The Company has operating leases for corporate offices, branch locations, and certain equipment. These leases generally have terms of 20 years or less, determined based on the contractual maturity of the lease, and include periods covered by options to extend or terminate the lease when the Company is reasonably certain that it will exercise those options. For the vast majority of the Company’s leases, we are not reasonably certain we will exercise our options to renew to the end of all renewal option periods. The Company determines if an arrangement is a lease at inception. Operating leases are included in other assets and other liabilities in the Consolidated Statements of Condition. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the vast majority of the leases do not provide an implicit rate, the incremental borrowing rate (FHLB borrowing rate) is used based on the information available at commencement date in determining the present value of lease payments. The implicit rate is used when readily determinable. The operating lease ROU asset is measured at cost, which includes the initial measurement of the lease liability, prepaid rent and initial direct costs incurred by the Company, less incentives received. Variable costs such as the proportionate share of actual costs for utilities, common area maintenance, property taxes and insurance are not included in the lease liability and are recognized in the period in which they are incurred.
Lessor Arrangements	The Company is a lessor in the equipment finance business where it has executed direct financing leases (“lease finance receivables”). The Company produces lease finance receivables through a specialty finance subsidiary that participates in syndicated loans that are brought to them, and equipment loans and leases that are assigned to them, by a select group of nationally recognized sources, and are generally made to large corporate obligors, many of which are publicly traded, carry investment grade or near-investment grade ratings, and participate in stable industries nationwide. Lease finance receivables are carried at the aggregate of lease payments receivable plus the estimated residual value of the leased assets and any initial direct costs incurred to originate these leases, less unearned income, which is accreted to interest income over the lease term using the interest method. The standard leases are typically repayable on a level monthly basis with terms ranging from 24 to 120 months. At the end of the lease term, the lessee usually has the option to return the equipment, to renew the lease or purchase the equipment at the then fair market value (“FMV”) price. For leases with a FMV renewal/purchase option, the relevant residual value assumptions are based on the estimated value of the leased asset at the end of the lease term, including evaluation of key factors, such as, the estimated remaining useful life of the leased asset, its historical secondary market value including history of the lessee executing the FMV option, overall credit evaluation and return provisions. The Company acquires the leased asset at fair market value and provides funding to the respective lessee at acquisition cost, less any volume or trade discounts, as applicable. Therefore, there is generally no selling profit or loss to recognize or defer at inception of a lease.
Asset Retirement Obligation	The Company’s pension benefit obligations and post-retirement health and welfare benefit obligations, and the related costs, are calculated using actuarial concepts in accordance with GAAP. The measurement of such obligations and expenses requires that certain assumptions be made regarding several factors, most notably including the discount rate and the expected rate of return on plan assets. The Company evaluates these assumptions on an annual basis. Other factors considered by the Company in its evaluation include retirement patterns and mortality rates.
Bank-Owned Life Insurance	The Company has purchased life insurance policies on certain employees. These BOLI policies are recorded in the Consolidated Statements of Condition at their cash surrender value. Income from these policies and changes in the cash surrender value are recorded in “Non-interest income” in the Consolidated Statements of Income and Comprehensive Income.
Business Combinations Policy	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, reflecting assumptions that a market participant would use when pricing an asset or liability. In some cases, the estimation of fair values requires management to make estimates about discount rates, future expected cash flows, market conditions, and other future events that are highly subjective in nature and are subject to change. Described below are the methods used to determine the fair values of the significant assets acquired and liabilities assumed in the Signature Transaction. Cash and Cash Equivalents The estimated fair value of cash and cash equivalents approximates their stated face amounts, as these financial instruments are either due on demand or have short-term maturities. Loans and leases The fair value for loans was based on a discounted cash flow methodology that considered credit loss expectations, market interest rates and other market factors such as liquidity from the perspective of a market participant. Loans were grouped together according to similar characteristics and were treated in the aggregate when applying various valuation techniques. The probability of default, loss given default and prepayment assumptions were the key factors driving credit losses which were embedded into the estimated cash flows. These assumptions were informed by internal data on loan characteristics, historical loss experience, and current and forecasted economic conditions. The interest and liquidity component of the estimate was determined by discounting interest and principal cash flows through the expected life of each loan. The discount rates used for loans are based on current market rates for new originations of comparable loans and include adjustments for liquidity. The discount rates do not include a factor for credit losses as that has been included as a reduction to the estimated cash flows. Acquired loans were marked to fair value and adjusted for any PCD gross up as of the date of the Signature Transaction. Deposit Liabilities The fair value of deposit liabilities with no stated maturity (i.e., non-interest-bearing and interest-bearing checking accounts) is equal to the carrying amounts payable on demand. The fair value of certificates of deposit represents contractual cash flows, discounted using interest rates currently offered on deposits with similar characteristics and remaining maturities. Core Deposit Intangible Core deposit intangible (“CDI”) is a measure of the value of non-interest-bearing and interest-bearing checking accounts, savings accounts, and money market accounts that are acquired in a business combination. The fair value of the CDI was determined using a discounted cashflow methodology which considered discount rate, customer attrition rates, and other relevant market assumptions. This method estimated the fair value by discounting the present value of the expected cost savings attributable to the core deposit funding, relative to an alternative source of funding. The CDI relating to the Signature Transaction will be amortized over an estimated useful life of 10 years using the sum of years digits depreciation method. The Company evaluates such identifiable intangibles for impairment when an indication of impairment exists. CDI does not significantly impact our liquidity or capital ratios. PCD loans The methods and significant assumptions used to estimate fair values for the Company’s financial instruments follow: Cash and Cash Equivalents Cash and cash equivalents include cash and due from banks and federal funds sold. The estimated fair values of cash and cash equivalents are assumed to equal their carrying values, as these financial instruments are either due on demand or have short-term maturities. Securities If quoted market prices are not available for a specific security, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics, or discounted cash flows. These pricing models primarily use market-based or independently sourced market parameters as inputs, including, but not limited to, yield curves, interest rates, equity or debt prices, and credit spreads. In addition to observable market information, pricing models also incorporate transaction details such as maturities and cash flow assumptions. Federal Home Loan Bank Stock Ownership in equity securities of the FHLB is generally restricted and there is no established liquid market for their resale. The carrying amount approximates the fair value. Loans and leases The Company discloses the fair value of loans measured at amortized cost using an exit price notion. The Company determined the fair value on substantially all of its loans for disclosure purposes, on an individual loan basis. The discount rates reflect current market rates for loans with similar terms to borrowers having similar credit quality on an exit price basis. For those loans where a discounted cash flow technique was not considered reliable, the Company used a quoted market price for each individual loan. MSRs The significant unobservable inputs used in the fair value measurement of the MSRs are option adjusted spreads, prepayment rates and cost to service. Significant increases (decreases) in all three assumptions in isolation result in a significantly lower (higher) fair value measurement. Weighted average life (in years) is used to determine the change in fair value of MSRs. For December 31, 2023, the weighted average life (in years) for the entire portfolio was 6.83. Rate lock commitments The significant unobservable input used in the fair value measurement of the rate lock commitments is the pull through rate. The pull through rate is a statistical analysis of our actual rate lock fallout history to determine the sensitivity of the residential mortgage loan pipeline compared to interest rate changes and other deterministic values. New market prices are applied based on updated loan characteristics and new fallout ratios (i.e. the inverse of the pull through rate) are applied accordingly. Significant increases (decreases) in the pull through rate in isolation result in a significantly higher (lower) fair value measurement. Deposits The fair values of deposit liabilities with no stated maturity (i.e., interest-bearing checking and money market accounts, savings accounts, and non-interest-bearing accounts) are equal to the carrying amounts payable on demand. The fair values of CDs represent contractual cash flows, discounted using interest rates currently offered on deposits with similar characteristics and remaining maturities. These estimated fair values do not include the intangible value of core deposit relationships, which comprise a portion of the Company’s deposit base. Borrowed Funds The estimated fair value of borrowed funds is based either on bid quotations received from securities dealers or the discounted value of contractual cash flows with interest rates currently in effect for borrowed funds with similar maturities and structures. Off-Balance Sheet Financial Instruments
Representation and Warranty Reserve	The Company reviews and updates the fair value hierarchy classifications for its assets on a quarterly basis. Changes from one quarter to the next that are related to the observability of inputs for a fair value measurement may result in a reclassification from one hierarchy level to another. A description of the methods and significant assumptions utilized in estimating the fair values of securities follows: Where quoted prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities include highly liquid government securities and exchange-traded securities. If quoted market prices are not available for a specific security, then fair values are estimated by using pricing models. These pricing models primarily use market-based or independently sourced market parameters as inputs, including, but not limited to, yield curves, interest rates, equity or debt prices, and credit spreads. In addition to observable market information, models incorporate transaction details such as maturity and cash flow assumptions. Securities valued in this manner would generally be classified within Level 2 of the valuation hierarchy, and primarily include such instruments as mortgage-related and corporate debt securities. Periodically, the Company uses fair values supplied by independent pricing services to corroborate the fair values derived from the pricing models. In addition, the Company reviews the fair values supplied by independent pricing services, as well as their underlying pricing methodologies, for reasonableness. The Company challenges pricing service valuations that appear to be unusual or unexpected.

Schedule of Adoption of New Accounting Standards	Adoption of New Accounting Standards Standard Description Effective Date ASU 2022-02- Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures Issued March 2022 ASU 2022-02 eliminates prior accounting guidance for TDRs, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. The standard also requires that an entity disclose current-period gross charge-offs by year of origination for financing receivables and net investments in leases. The Company adopted ASU 2022-02 effective January 1, 2023 using a modified retrospective transition approach for the amendments related to the recognition and measurement of TDRs. The impact of the adoption resulted in an immaterial change to the allowance for credit losses ("ACL"), thus no adjustment to retained earnings was recorded. Disclosures have been updated to reflect information on loan modifications given to borrowers experiencing financial difficulty as presented in Note 6. TDR disclosures are presented for comparative periods only and are not required to be updated in current periods. Additionally, the current year vintage disclosure included in Note 6 has been updated to reflect gross charge-offs by year of origination for the three months ended September 30, 2023. ASU 2023-02 Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method Issued: March 2023 ASU 2023-02 permits reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. The Company adopted ASU 2023-02 effective January 1, 2023 and it did not have a significant impact on the Company's consolidated financial statements.
