Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	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 436 branches across nine 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 3,000 third-party mortgage originators. Flagstar Bank N.A. also operates through eight local divisions, each with a history of service and strength: 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. 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 11 “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 Corporation 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.

Earnings Per Share [Abstract]
Computation of Earnings per Common Share	Computation of Earnings per Common Share 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: Three Months Ended September 30, Nine Months Ended September 30, (in millions, except share and per share amounts) 2023 2022 2023 2022 Net income available to common stockholders $ 199 $ 144 $ 2,601 $ 453 Less: Dividends paid on and earnings allocated to participating securities (2) (2) (27) (6) Earnings applicable to common stock $ 197 $ 142 $ 2,574 $ 447 Weighted average common shares outstanding 722,486,509 465,115,180 710,684,522 465,354,754 Basic earnings per common share $ 0.27 $ 0.31 $ 3.62 $ 0.96 Earnings applicable to common stock $ 197 $ 142 $ 2,574 $ 447 Weighted average common shares outstanding 722,486,509 465,115,180 710,684,522 465,354,754 Potential dilutive common shares 2,426,381 979,177 1,753,527 926,184 Total shares for diluted earnings per common share computation 724,912,890 466,094,357 712,438,049 466,280,938 Diluted earnings per common share and common share equivalents $ 0.27 $ 0.30 $ 3.61 $ 0.96

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, 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 estimated fair values based on initial valuations as of March 20, 2023. 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 September 30, 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 net assets acquired and the estimated fair value adjustments resulting in the bargain purchase gain is as follows: (in millions) March 20, 2023 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 53 Change in deferred tax liability 88 Bargain purchase gain on Signature Transaction, as adjusted $ 2,142 In connection with the Signature Transaction, the Company recorded a bargain purchase gain, as adjusted, of approximately $2.1 billion during the nine months ended September 30, 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) As Initially Reported Measurement Period Adjustments As Adjusted Purchase Price consideration $ 85 $ — $ 85 Fair value of assets acquired: Cash & cash equivalents 25,043 — 25,043 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 (646) 37,990 Fair value of liabilities assumed: Deposits 33,568 — 33,568 Other liabilities 2,982 (787) 2,195 Total liabilities assumed 36,550 (787) 35,763 Fair value of net identifiable assets 2,086 141 2,227 Bargain purchase gain $ 2,001 $ 141 $ 2,142 During the nine months ended September 30, 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. 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 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 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 quarter and year-to-date periods ended September 30, 2023 include the operating results of the acquired assets and assumed liabilities of Signature Bridge Bank, N.A. 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 Bridge Bank, N.A. was only in operation from March 12 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 Bank

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, 133 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 September 30, 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 September 30, 2023.

(2) Includes specialty finance loans and leases of $5.2 billion and $4.4 billion at September 30, 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 September 30, 2023, LGG loans totaled $563 million and the repurchase liability was $362 million. Repossessed assets and the associated net claims related to government guaranteed loans are recorded in other assets and was $12 million at September 30, 2023. Loans Held-for-Sale Loans held-for-sale at September 30, 2023 totaled $1.9 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 September 30, 2023 and December 31, 2022 we had no loans that were nonperforming and still accruing.

(2) Pass includes 1-6W. The preceding classifications are the most current ones available and generally have been updated within the last twelve months. 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. The following table presents, by credit quality indicator, loan class, and year of origination, the amortized cost basis of the Company’s loans and leases as of September 30, 2023: Vintage Year (in millions) 2023 2022 2021 2020 2019 Prior To 2019 Revolving Loans Revolving Loans Converted to Term Loans Total Pass (1) $ 2,218 $ 13,695 $ 10,148 $ 9,547 $ 5,247 $ 11,115 $ 1,972 $ 7 $ 53,949 Special Mention 2 46 26 176 211 758 — — 1,219 Substandard 44 18 32 38 331 1,342 — 3 1,808 Doubtful — — — — — — — — — Total mortgage loans $ 2,264 $ 13,759 $ 10,206 $ 9,761 $ 5,789 $ 13,215 $ 1,972 $ 10 $ 56,976 Current-period gross writeoffs — — — — (2) (17) — — (19) Pass (1) $ 8,458 $ 3,924 $ 1,980 $ 1,619 $ 993 $ 1,021 $ 8,418 $ 321 $ 26,734 Special Mention 7 24 6 3 37 13 4 — 94 Substandard 16 28 21 16 5 46 42 10 184 Doubtful — — 7 — — — — — 7 Total other loans $ 8,481 $ 3,976 $ 2,014 $ 1,638 $ 1,035 $ 1,080 $ 8,464 $ 331 $ 27,019 Current-period gross writeoffs $ (6) $ (2) $ (1) $ (1) $ (2) $ (3) $ — $ — $ (15) Total $ 10,745 $ 17,735 $ — $ 12,220 $ 11,399 $ 6,824 $ 14,295 $ 10,436 $ 341 $ 83,995 (1) Pass includes 1-6W. When management determines that foreclosure is probable, for loans that are individually evaluated the expected credit losses are based on the fair value of the collateral adjusted for selling costs. 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 September 30, 2023: Collateral Type (in millions) Real Property Other Multi-family $ 102 $ — Commercial real estate 170 — One-to-four family first mortgage 100 — Commercial and industrial — 33 Other — — Total collateral-dependent loans held for investment $ 372 $ 33 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 three and nine months ended September 30, 2023. At September 30, 2023 and December 31, 2022, the Company had $92 million and $121 million of residential mortgage loans in the process of foreclosure and no residential mortgage loans in the process of foreclosure, respectively. 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 - 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 Three months ended September 30, 2023 Multi-family $ 100 $ — $ — $ 100 0.95 % Commercial real estate 67 — — 67 0.64 % One-to-four family first mortgage 3 1 2 6 0.10 % Commercial and Industrial 1 11 2 14 0.07 % Other Consumer — — 1 1 0.04 % Total $ 171 $ 12 $ 5 $ 188 Nine months ended September 30, 2023 Multi-family $ 100 $ — $ — $ 100 0.95 % Commercial real estate 119 — — 119 1.13 % One-to-four family first mortgage 3 4 5 12 0.20 % Commercial and Industrial 1 18 2 21 0.09 % Other Consumer $ — $ — $ 1 1 0.04 % Total $ 223 $ 22 $ 8 $ 253 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) Three months ended September 30, 2023 Multi-family 7.73 % 6.17 % Commercial real estate 10.77 % 4.32 % One-to-four family first mortgage — % — % 9.9 Commercial and industrial 8.02 % 7.74 % 0.36 Other Consumer 9.28 % 4.75 % 4.8 Nine months ended September 30, 2023 Multi-family 7.73 % 6.17 % Commercial real estate 10.48 % 4.18 % One-to-four family first mortgage — % — % 12.1 Commercial and industrial 8.02 % 7.74 % 0.46 Other Consumer 14.49 % 8.00 % 4.8 As of September 30, 2023, there were $3 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 $5 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: September 30, 2023 (dollars in millions) Current 30 - 89 Past Due 90+ Past Due Total One-to-four family first mortgage 1 — 9 10 Commercial and industrial 21 — — 21 Other Consumer 1 — — 1 Total $ 23 $ — $ 9 $ 32 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 loan and lease losses, 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 September 30, 2022, loans on which concessions were made with respect to rate reductions and/or extension of maturity dates amounted to $45 million. The following table presents information regarding the Company's TDRs as of September 30, 2022: September 30, 2022 (dollars in millions) Accruing Non- Accrual Total Loan Category: Multi-family $ — $ 6 $ 6 Commercial real estate 16 19 35 Commercial and industrial (1) — 4 4 Total $ 16 $ 29 $ 45 (1) Includes $4 million of taxi medallion-related loans at September 30, 2022.

The day 1 impact of the Signature Transaction that closed on March 20, 2023 added $138 million to the reserve. The remaining net increase of approximately $88 million was driven by changes in the macroeconomic forecasts, specifically the inflationary pressures leading to sharp increases in interest rates and a slow-down of prepayment activity leading to longer weighted average lives on the balance sheet. In addition, the increase reflects unfavorable market conditions in the CRE portfolio (primarily office). As of September 30, 2023 and December 31, 2022, the allowance for unfunded commitments totaled $48 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 September 30, 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 $256 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: (in millions) For the three months ended September 30, 2023 For the nine months ended September 30, 2023 For the three months ended September 30, 2022 For the nine months ended September 30, 2022 Interest income on lease financing (1) $ 28 $ 80 $ 14 $ 38 (1) Included in Interest Income – Loans and leases in the Consolidated Statements of Income and Comprehensive Income. At September 30, 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) September 30, 2023 December 31, 2022 Net investment in the lease - lease payments receivable $ 3,161 $ 1,685 Net investment in the lease - unguaranteed residual assets 296 60 Total lease payments $ 3,457 $ 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) September 30, 2023 2023 $ 159 2024 573 2025 659 2026 800 2027 503 Thereafter 763 Total lease payments $ 3,457 Plus: deferred origination costs 17 Less: unearned income (243) Less: purchase accounting adjustment $ (83) Total lease finance receivables, net $ 3,148 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 operating lease right-of-use assets and operating lease 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: (in millions) For the three months ended September 30, 2023 For the nine months ended September 30, 2023 For the three months ended September 30, 2022 For the nine months ended September 30, 2022 Operating lease cost $ 25 $ 60 $ 7 $ 21 Sublease income — — — — Total lease cost $ 25 $ 60 $ 7 $ 21 Supplemental cash flow information related to the leases for the following periods: (in millions) For the three months ended September 30, 2023 For the nine months ended September 30, 2023 For the three months ended September 30, 2022 For the nine months ended September 30, 2022 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 16 $ 46 $ 7 $ 21 Supplemental balance sheet information related to the leases for the following periods: (in millions, except lease term and discount rate) September 30, 2023 December 31, 2022 Operating Leases: Operating lease right-of-use assets (1) $ 442 $ 119 Operating lease liabilities (2) $ 456 $ 122 Weighted average remaining lease term 11.9 years 6 years Weighted average discount rate % 4.53 % 3.85 % (1) Included in Other assets in the Consolidated Statements of Condition.

At September 30, 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) September 30, 2023 December 31, 2022 Net investment in the lease - lease payments receivable $ 3,161 $ 1,685 Net investment in the lease - unguaranteed residual assets 296 60 Total lease payments $ 3,457 $ 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) September 30, 2023 2023 $ 159 2024 573 2025 659 2026 800 2027 503 Thereafter 763 Total lease payments $ 3,457 Plus: deferred origination costs 17 Less: unearned income (243) Less: purchase accounting adjustment $ (83) Total lease finance receivables, net $ 3,148 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 operating lease right-of-use assets and operating lease 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: (in millions) For the three months ended September 30, 2023 For the nine months ended September 30, 2023 For the three months ended September 30, 2022 For the nine months ended September 30, 2022 Operating lease cost $ 25 $ 60 $ 7 $ 21 Sublease income — — — — Total lease cost $ 25 $ 60 $ 7 $ 21 Supplemental cash flow information related to the leases for the following periods: (in millions) For the three months ended September 30, 2023 For the nine months ended September 30, 2023 For the three months ended September 30, 2022 For the nine months ended September 30, 2022 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 16 $ 46 $ 7 $ 21 Supplemental balance sheet information related to the leases for the following periods: (in millions, except lease term and discount rate) September 30, 2023 December 31, 2022 Operating Leases: Operating lease right-of-use assets (1) $ 442 $ 119 Operating lease liabilities (2) $ 456 $ 122 Weighted average remaining lease term 11.9 years 6 years Weighted average discount rate % 4.53 % 3.85 % (1) Included in Other assets in the Consolidated Statements of Condition.

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 14 - Derivative and Hedging Activities. Changes in the fair value of residential first mortgage MSRs were as follows: (in millions) Three Months Ended September 30, 2023 Nine Months Ended September 30, 2023 Balance at beginning of period $ 1,031 $ 1,033 Additions from loans sold with servicing retained 67 148 Reductions from sales — (51) Decrease in MSR fair value due to pay-offs, pay-downs, run-off, model changes, and other (1) (20) (54) Changes in estimates of fair value due to interest rate risk (1) (2) 57 59 Fair value of MSRs at end of period $ 1,135 $ 1,135 (1) Changes in fair value are included within net return on mortgage servicing rights on the Consolidated Statements of Income and Comprehensive Income. (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: September 30, 2023 Fair Value (dollars in millions) Actual 10% adverse change 20% adverse change Option adjusted spread 5.6 % $ 1,114 $ 1,094 Constant prepayment rate 7.3 % 1,100 1,068 Weighted average cost to service per loan $ 69 $ 1,124 $ 1,114 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 16 - 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.

Disclosure of Transfer of Securitizations or Asset-Backed Financing Financial Assets Accounted for as Sale [Abstract]
Variable Interest Entities	Variable Interest Entities    We have no consolidated VIEs as of September 30, 2023 and December 31, 2022. In connection with our non-qualified mortgage securitization activities, we have retained a five percent interest in the investment securities of certain trusts ("other MBS") and are contracted as the subservicer of the underlying loans, compensated based on market rates, which constitutes a continuing involvement in these trusts. Although we have a variable interest in these securitization trusts, we are not their primary beneficiary due to the relative size of our investment in comparison to the total amount of securities issued by the VIE and our inability to direct activities that most significantly impact the VIE’s economic performance. As a result, we have not consolidated the assets and liabilities of the VIE in our Consolidated Statements of Condition. The Bank’s maximum exposure to loss is limited to our five percent retained interest in the investment securities that had a fair value of $174 million as of September 30, 2023 as well as the standard representations and warranties made in conjunction with the loan transfers.

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 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 hedge transaction is recognized in earnings. At September 30, 2023, the Company had $110 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 September 30, 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 real estate loans using the portfolio layer method. For the three months ended September 30, 2023 , the floating rate received related to the net settlement of this interest rate swap 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 $8 million and $15 million for three months and nine months September 30, 2023, 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 $6.4 billion at September 30, 2023 , of which unrealized gains of $46 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 September 30, 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 September 30, 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: (in millions) For the Nine Months Ended September 30, 2023 For the Year Ended December 31, 2022 For the Nine Months Ended September 30, 2022 Amount of gain (loss) recognized in AOCL $ 98 $ 88 $ 64 Amount of reclassified from AOCL to interest expense $ (19) $ (4) $ 4 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.

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 September 30, 2023 and December 31, 2022, and that were included in the Company’s Consolidated Statements of Condition at those dates: September 30, 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 $ — $ 1,164 $ — $ — $ 1,164 GSE CMOs $ — $ 4,351 $ — $ — $ 4,351 Private Label CMOs $ — $ 142 $ 32 $ — $ 174 Total mortgage-related debt securities $ — $ 5,657 $ 32 $ — $ 5,689 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. Fair Value Measurements Using Significant Unobservable Inputs The following tables include a roll forward of the Consolidated Statements of Condition amounts (including the change in fair value) for financial instruments classified by us within Level 3 of the valuation hierarchy: (dollars in millions) Balance at Beginning of Year Total Gains / (Losses) Recorded in Earnings (1) Purchases / Originations Sales Settlement Transfers In (Out) Balance at End of Year Three Months Ended September 30, 2023 Assets Mortgage servicing rights (1) $ 1,031 $ 37 $ 67 $ — — — $ 1,135 Private Label CMOs — — — — — 32 32 Rate lock commitments (net) (1)(2) — (42) 30 — — 6 (6) Totals $ 1,031 $ (5) $ 97 $ — $ — $ 38 $ 1,161 Nine Months Ended September 30, 2023 Assets Mortgage servicing rights (1) $ 1,033 $ 5 $ 148 $ (51) — — $ 1,135 Private Label CMOs — — — — — 32 32 Rate lock commitments (net) (1)(2) (1) (70) 90 — — (25) (6) Totals $ 1,032 $ (65) $ 238 $ (51) $ — $ 7 $ 1,161 (1) We utilized swaptions, futures, forward agency and loan sales and interest rate swaps to manage the risk associated with mortgage servicing rights and rate lock commitments. Gains and losses for individual lines do not reflect the effect of our risk management activities related to such Level 3 instruments. (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. The following tables present the quantitative information about recurring Level 3 fair value financial instruments and the fair value measurements as of September 30, 2023: Fair Value Valuation Technique Unobservable Input (1) Range (Weighted Average) (dollars in millions) Assets Mortgage servicing rights $ 1,135 Discounted cash flows Option adjusted spread 5.2% - 21.7% 5.6% Constant prepayment rate —% - 10.0% 7.3% Weighted average cost to service per loan $65 - $90 $69 Private Label CMOs $ 32 Discounted cash flows Constant default rates 0.10% - 0.30% Weighted average life 8.2 - 11.9 Rate lock commitments (net) $ (6) Consensus pricing Origination pull-through rate 71.10% (1) Unobservable inputs were weighted by their relative fair value of the instruments. 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 September 30, 2023 and December 31, 2022, and that were included in the Company’s Consolidated Statements of Condition at those dates: Fair Value Measurements at September 30, 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 (2) $ 162 $ 162 Other assets (1) $ 46 $ 46 Total $ — $ — $ 208 $ 208 (1) Represents the fair value of repossessed assets, based on the appraised value of the collateral subsequent to its initial classification as repossessed assets and equity securities without readily determinable fair values.

(2) Represents the fair value of impaired loans, based on the value of the collateral. 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 September 30, 2023 and December 31, 2022: September 30, 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 $ 6,929 $ 6,929 $ 6,929 $ — $ — FHLB and FRB stock (1) 1,110 1,110 — 1,110 — Loans and leases held for investment, net 83,376 80,331 — — 80,331 Financial Liabilities: Deposits $ 82,675 $ 82,494 $ 65,365 (2) $ 17,129 (3) $ — Borrowed funds 14,585 14,317 — 14,317 — (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 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. The estimated fair values of non-performing mortgage and other loans are based on recent collateral appraisals. 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 September 30, 2023, the weighted average life (in years) for the entire portfolio was 7.44. 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 September 30, 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 Three Months ended September 30, For the Nine Months Ended September 30, (dollars in millions) 2023 2023 Assets Loans held-for-sale $ — $ — Net gain on loan sales $ (25) $ 4 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: September 30, 2023 (dollars in millions) Unpaid Principal Balance Fair Value Fair Value Over / (Under) UPB Assets: Nonaccrual loans: Loans held-for-sale $ 2 $ 2 $ — Loans held-for-investment — — — Total non-accrual loans $ 2 $ 2 $ — Other performing loans: Loans held-for-sale $ 1,310 $ 1,316 $ 6 Total other performing loans $ 1,310 $ 1,316 $ 6 Total loans: Loans held-for-sale $ 1,312 $ 1,318 $ 6 Total loans $ 1,312 $ 1,318 $ 6 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

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	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 11 “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.
Recently Adopted 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.
Earnings per Common Share (Basic and Diluted)	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.
Lessor Arrangements	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.
Lessee Arrangements	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 operating lease right-of-use assets and operating lease 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.
Fair Value Measurements	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.
