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 Office of the Comptroller of the Currency. 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 ($2.79 per share on a split-adjusted basis, reflecting the impact of ten stock splits between 1994 and 2024). 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 (as defined within Note 3 - Business Combinations) which closed on March 20, 2023. Flagstar Bank, N.A. currently operates 419 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 3,000 third-party mortgage originators. 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 protect against temporary mismatches between sources and uses of funds caused by variable loan and deposit demand, and to meet our financial obligations. Basis of Presentation See Note 1 to the Consolidated Financial Statements in the Company's Annual Report on Form 10-K/A for the year ended December 31, 2023 for information on the Company's accounting policies. The accompanying financial statements of the Company and other entities in which the Company has a controlling financial interest, have been prepared using U.S. generally accepted accounting principles for interim financial statements. The accompanying financial statements of the Company conform to U.S. generally accepted accounting principles and to general practices within the banking industry. The preparation of financial statements in conformity with U.S. generally accepted accounting principles 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 and the acquisition method of accounting. 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. Adoption of New Accounting Standards Standard Description Effect on Financial Statements ASU 2022-03, Fair Value Measurements (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions This Accounting Standards Update ("ASU") clarifies that a contractual restriction on the sale of an equity security should not be considered in measuring its fair value. In addition, the ASU requires specific disclosures related to equity securities that are subject to contractual sale restrictions. Adoption of this ASU did not have a material impact on the consolidated financial statements. ASU 2023-08, Intangibles—Goodwill and Other—Crypto Assets (Subtopic 350-60): Accounting for and Disclosure of Crypto Assets The amendments in this update require entities that hold certain crypto assets to measure such assets at fair value and recognize any changes in fair value in net income in each reporting period, along with other presentation and disclosure matters. Adoption of this ASU did not have an impact on the consolidated financial statements as the Company does not hold and has no plans to hold crypto assets. ASU 2024-02, Codification Improvements—Amendments to Remove References to the Concepts Statements This Update contains amendments to the Codification that remove references to various Concepts Statements. In most instances, the references are extraneous and not required to understand or apply the guidance. We early adopted this ASU which did not have a material impact on the consolidated financial statements. Accounting Standards Issued But Not Yet Adopted Standard Description Effect on Financial Statements Date of Required Adoption ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative This ASU clarifies and improves disclosure requirements for a variety of topics. The amendments should be applied prospectively. The adoption of this ASU is not expected to have a material impact on the consolidated financial statements and disclosures. The date on which the SEC’s removal of related disclosures from Regulation S-X or Regulation S-K becomes effective. Early adoption is prohibited. ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures The amendments in this update require certain disclosures related to segment reporting in annual and interim periods. The ASU also clarifies that companies may report on additional measures if the chief operating decision maker uses more than one measure of a segment’s profit or loss in assessing segment performance and deciding how to allocate resources. The ASU should be applied on a retrospective basis. We are in the process of assessing the impact of the adoption of this ASU on the consolidated financial statements and disclosures. Annual periods beginning January 1, 2024 Interim periods beginning January 1, 2025 Early adoption is permitted. ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures The ASU improves the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures. The guidance should be applied on a prospective or retrospective basis. We are in the process of assessing the impact of the adoption of this ASU on the consolidated financial statements and disclosures. January 1, 2025 Early adoption is permitted. ASU 2024-01, Compensation—Stock Compensation (Topic 718): Scope Application for Profits Interest and Similar Awards This guidance provides the addition of illustrative examples clarifying the accounting for profits interest and similar awards. The guidance should be applied on a prospective or retrospective basis. The adoption of this ASU is not expected to have a material impact on the consolidated financial statements and disclosures. January 1, 2025 Early adoption is permitted.

Computation of Earnings per Com

Earnings Per Share [Abstract]
Computation of Earnings per Common Share	Computation of Earnings per Common Share Earnings per Common Share (Basic and Diluted) Basic earnings per share is computed by dividing the net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed using the same method as basic earnings per share, however, the computation reflects the potential dilution that would occur if outstanding in-the-money stock options were exercised and converted into common stock. Diluted earnings per share is the amount of earnings available to each common share outstanding during the reporting periods adjusted to include the effects of potentially dilutive common shares. Potentially dilutive common shares include warrants, convertible preferred stock, stock options and other stock-based awards. Potentially dilutive common shares are excluded from the computation of diluted earnings per share in the periods where the effect would be antidilutive. As the average common share price was above the $7.50 per share exercise price (on an as-converted common stock basis) of the warrants, the corresponding 105 million common shares underlying the shares of non-voting, common-equivalent preferred stock of the Company, par value $0.01 per share (the "Series D NVCE Stock"), underlying such warrants would have been included in the dilutive share count if the Company had positive earnings for the period (reflective of the reverse stock split discussed in Note 19 - Subsequent Events). 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 earnings per share. Under the two-class method, all earnings (distributed and undistributed) are allocated to common stock 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 reflects basic and diluted weighted average shares and net income (loss) per share giving effect to the reverse stock split as if it had been effective for all periods presented (See Note 19 - Subsequent Events): Three Months Ended June 30, Six Months Ended June 30, (in millions, except share and per share amounts) 2024 2023 2024 2023 Net (loss) income available to common stockholders $ (333) $ 405 $ (668) $ 2,403 Less: Dividends paid on and earnings allocated to participating securities — (4) — (26) (Loss) earnings applicable to common stock $ (333) $ 401 $ (668) $ 2,377 Weighted average common shares outstanding (1) 293,122,116 240,754,856 269,902,354 234,895,240 Basic (loss) earnings per common share $ (1.14) $ 1.66 $ (2.48) $ 10.12 (Loss) earnings applicable to common stock $ (333) $ 401 $ (668) $ 2,377 Weighted average common shares outstanding (1) 293,122,116 240,754,856 269,902,354 234,895,240 Potential dilutive common shares — 487,475 — 470,508 Total shares for diluted earnings per common share computation (1) 293,122,116 241,242,331 269,902,354 235,365,748 Diluted (loss) earnings per common share and common share equivalents $ (1.14) $ 1.66 $ (2.48) $ 10.10 (1) On June 27, 2024, the Company announced a 1 for 3 reverse stock split, which was effected July 11, 2024.

Business Combination, Asset Acquisition, and Joint Venture Formation [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 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. The final settlement process between the Company and the FDIC concluded upon the one-year anniversary of the Signature Transaction. 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 13,010,668 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 Accounting Standards Codification ("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 Company recorded the estimated fair value of the assets acquired and liabilities assumed as of March 20, 2023, which was subject to adjustment for up to one year after March 20, 2023 (the “Measurement Period”). The Measurement Period concluded on March 20, 2024, and the Company has finalized its review of the assets acquired and liabilities assumed. Under the Agreement, the Company provided 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 FDIC reimbursed the Company for costs associated with the Interim Servicing based upon an agreed upon fee which approximates the cost to provide such services. The Interim Servicing was completed in March 2024. 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. 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 Adjustments related to items identified subsequent to the initial reporting period as of March 20, 2023: Measurement period adjustments, excluding taxes (134) Change in deferred tax liability 143 Bargain purchase gain on Signature Transaction, as adjusted $ 2,010 In connection with the Signature Transaction, the Company recorded a bargain purchase gain, as adjusted, of approximately $2.0 billion. This includes a $121 million reduction in the bargain purchase gain during the three months ended March 31, 2024, due to final adjustments to the fair value of assets received and liabilities assumed, including the in-transit and other shared accounts. This adjustment is included in non-interest income in the Company’s Consolidated Statement of Income and Comprehensive Income for the six months ended June 30, 2024. No adjustments have been made subsequent to the conclusion of the Measurement Period on March 20, 2024. 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 was influenced significantly by the FDIC-assisted transaction process. The assets acquired and liabilities assumed and consideration paid in the Signature Transaction were recorded at their estimated fair values based on management’s best estimates using information available at the date of the Signature Transaction. The following table provides the purchase price allocation to the assets acquired and liabilities assumed at their estimated fair values as of the date of the Signature Transaction: (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 (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 (266) 413 Total assets acquired 38,636 (885) 37,751 Fair value of liabilities assumed: Deposits 33,568 (61) 33,507 Other liabilities 2,982 (833) 2,149 Total liabilities assumed 36,550 (894) 35,656 Fair value of net identifiable assets 2,086 9 2,095 Bargain purchase gain $ 2,001 $ 9 $ 2,010 During the Measurement Period, the Company recorded adjustments to the estimated fair value of loans and leases acquired based on information received after the transaction date, and to adjust other assets and accrued expenses and other liabilities for balances ultimately retained by the FDIC. 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 has incurred approximately $259 million in costs related to the Signature Transaction primarily for legal, advisory, system conversion 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. See Note 3 - Business Combinations to the Consolidated Financial Statements in the Company's Annual Report on Form 10-K/A for the year ended December 31, 2023 for information regarding the Signature Transaction, including methods used to determine the fair values of the significant assets acquired and liabilities assumed. Unaudited Pro Forma Information – Signature Transaction The Company’s operating results for the year ended December 31, 2023 and the three and six months ended June 30, 2024 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.

Dividends accrue on the shares at a fixed rate equal to 6.375 percent per annum until March 17, 2027, and a floating rate equal to three-month Secured Overnight Financing Rate plus 408.26 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. In the second quarter of 2024, we paid dividends on our Series A preferred stock of $15.94 per share. Series B Preferred Stock As of June 30, 2024, each share of Series B Noncumulative Convertible Preferred Stock (the “Series B Preferred Stock”) was automatically convertible into 1,000 shares of our common stock (or one share of Series C Preferred Stock in limited circumstances) in the event of a transfer consistent with the rules and limitations of Regulation Y (a "Reg Y Transfer"). As of June 30, 2024, the issued and outstanding shares of Series B Preferred Stock represented the right (on an as converted basis) to receive approximately 64 million shares of our common stock. Series B Preferred Stock shareholders do not have voting rights, except in limited circumstances. On June 5, 2024, shareholders approved (a) an amendment to the Amended and Restated Certificate of Incorporation of the Company to increase the number of authorized shares of our common stock from 300,000,000 to 666,666,666; and (b) the issuance of shares of our common stock in connection with the March 2024 capital raise pursuant to New York Stock Exchange listing rules (the “Stockholder Approvals”). In accordance with the Series B Preferred Stock Certificate of Designations, upon obtaining the Stockholder Approvals, the quarterly non-cumulative cash dividend (annual rate of 13 percent) and liquidation preference rights ceased to apply. Shares of Series B Preferred Stock (a) are now entitled to receive dividends at the same time and on the same terms as the holders of common stock, including for the dividend declared and paid by the Company on June 17, 2024, and (b) rank as equal to the Common Stock in any liquidation of the Company. The Series B Preferred Stock is classified in mezzanine equity as it is contingently convertible into shares of preferred stock that are redeemable for cash, contingent on events that are not solely in the control of the Company. The Series B Preferred Stock is not remeasured because it is currently not probable that it will become redeemable. Series C Preferred Stock All of the issued and outstanding shares of the Company's Series C Noncumulative Convertible Preferred Stock (“Series C Preferred Stock”) have converted into shares of common stock in accordance with the terms of the Series C Certificate of Designation as of June 30, 2024. Warrants Warrants to purchase shares of a new class of non-voting, common-equivalent preferred stock of the Company, par value $0.01 per share (the "Series D NVCE Stock") for an initial exercise price of $2,500 per share were issued in conjunction with the March 2024 capital raise. The warrants are not exercisable until September 10, 2024 and expire 7 years after issuance. Pursuant to the terms of the Warrant, as a result of the dividend paid on shares of our common stock on June 17, 2024, the exercise price of the Warrants was reduced to $2,492. The terms of the Warrants prescribe net settlement in shares. All the Warrants issued and outstanding as of June 30, 2024 entitled the holders thereof to receive 315,000 shares of Series D NVCE Stock (subject to net settlement of shares). As of June 30, 2024, no shares of Series D Non-Voting Common Equivalent Stock of the Company (“Series D NVCE Stock”) have been issued. Shares of Series D NVCE Stock are issuable upon the exercise of the Warrant.

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 these 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. During the three months ended June 30, 2024 the Company recorded a $3 million allowance for credit losses related to a corporate debt security compared to $1 million recorded during the three months ended March 31, 2024.

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 loans held for investment. We report loans held for investment 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: June 30, 2024 December 31, 2023 (dollars in millions) Amount Percent of Amount Percent of Loans and Leases Held for Investment: Multi-family $ 36,011 48.3 % $ 37,265 44.0 % Commercial real estate 9,961 13.3 % 10,470 12.4 % One-to-four family first mortgage 5,790 7.8 % 6,061 7.2 % Acquisition, development, and construction 3,217 4.3 % 2,912 3.4 % Commercial and industrial (1) 15,088 20.2 % 22,065 26.1 % Lease financing, net of unearned income of $218 and $258, respectively 2,731 3.7 % 3,189 3.8 % Other 1,754 2.4 % 2,657 3.1 % Total loans and leases held for investment (2) $ 74,552 100.0 % $ 84,619 100.0 % Allowance for credit losses on loans and leases (1,268) (992) Total loans and leases held for investment, net 73,284 83,627 Loans held for sale, at fair value 7,845 1,182 Total loans and leases, net $ 81,129 $ 84,809 (1) Includes specialty finance loans and leases of $4.8 billion and $5.2 billion at June 30, 2024 and December 31, 2023, respectively. (2) Excludes accrued interest receivable of $376 million and $423 million at June 30, 2024 and December 31, 2023, respectively, which is included in other assets in the Consolidated Statements of Condition. Loans Held for Sale Loans held for sale at June 30, 2024 totaled $7.8 billion, up from $1.2 billion at December 31, 2023. During the second quarter, we transferred all warehouse loans from the commercial and industrial portfolio within loans held for investment to loans held for sale. This balance was $6.4 billion at June 30, 2024. We classify loans as held for sale when we originate or purchase loans that we intend to sell and when we change our intent about holding for investment. Loans held for sale are carried at fair value. 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. Subsequent to June 30, 2024, approximately $6 billion of the warehouse loans were sold at their carrying amounts. Refer to Note 19 - Subsequent Events. Asset Quality All asset quality information excludes loans with government guarantees that are insured by U.S. government agencies. A s of June 30, 2024, these loans totaled $486 million. 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 recording interest income, and previously accrued interest is reversed against interest income. A loan is only returned to accrual status when the loan is current and management has reasonable assurance that the loan will be fully collectible. Interest received on non-accrual loans is recorded as a reduction in the carrying amount. At June 30, 2024 and December 31, 2023 we had no loans that were 90 days or more past due 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 non-accrual loans, which based on existing circumstances, have weaknesses that make collection or liquidation in full highly questionable and improbable. One-to-four family loans are classified based on the duration of the delinquency. 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 commercial real estate 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. Commercial real estate 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 recorded investment of the Company’s collateral-dependent loans held for investment by collateral type as of June 30, 2024: Collateral Type (in millions) Real Property Other Multi-family $ 896 $ — Commercial real estate 769 — One-to-four family first mortgage 106 — Acquisition, development, and construction 19 — Commercial and industrial — 240 Total collateral-dependent loans held for investment $ 1,790 $ 240 At June 30, 2024 and December 31, 2023, the Company had $59 million and $81 million of residential mortgage loans in the process of foreclosure, respectively. Modifications to Borrowers Experiencing Financial Difficulty 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 June 30, 2024 One-to-four family first mortgage — 4 1 5 0.09 % Total $ — $ 4 $ 1 $ 5 Three Months Ended June 30, 2023 Commercial real estate 8 — — 8 0.08 % One-to-four family first mortgage — 2 2 4 0.07 % Commercial and industrial — 7 — 7 0.03 % Total $ 8 $ 9 $ 2 $ 19 Six Months Ended June 30, 2024 Multi-family $ 2 $ — $ — $ 2 0.01 % Commercial real estate 8 4 — 12 0.12 % One-to-four family first mortgage — 5 2 7 0.12 % Commercial and industrial — 7 1 8 0.04 % Total $ 10 $ 16 $ 3 $ 29 Six Months Ended June 30, 2023 Commercial real estate 52 — — 52 0.49 % One-to-four family first mortgage — 3 3 6 0.10 % Commercial and industrial — 7 — 7 0.03 % Total $ 52 $ 10 $ 3 $ 65 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 June 30, 2024 One-to-four family first mortgage 4.76 % 3.65 % 10.56 Commercial and industrial 8.51 6.00 1.0 Three Months Ended June 30, 2023 Commercial real estate 8.00 % 4.0 % One-to-four family first mortgage 6.05 4.8 13.6 Commercial and industrial — — 0.76 Six months ended June 30, 2024 Multi-family 8.08 % 6.0 % Commercial real estate 8.13 7.0 One-to-four family first mortgage 4.69 3.7 12.2 Commercial and industrial 7.44 6.3 0.4 Other Consumer 10.72 4.3 1.8 Six months ended June 30, 2023 Commercial real estate 10.09 % 4.0 % One-to-four family first mortgage 5.47 4.4 13.0 Commercial and industrial — — 0.76 As of June 30, 2024, there were $1 million one-to-four family first mortgages that were modified for borrowers experiencing financial difficulty that received term extension and subsequently defaulted during the first six months of 2024 and $2 million one-to-four family first mortgages that were combination modifications and subsequently defaulted during the first six months of 2024. As of June 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 first six months of 2023 and $3 million one-to-four family first mortgages that were combination modifications and subsequently defaulted during the first six months of 2023. 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.

Market interest rates remain persistently high which will put pressure on the ability for certain borrowers with interest rates resetting at current levels to cover debt service. When combined with inflationary pressure on operating costs and limits on the ability to increase rental rates, debt service levels may approach or exceed some properties' net operating income, which increases the risk of loss. We believe that higher interest rates for a longer period of time will have a more significant impact on our loans that will reprice during the next 18 months. Therefore, we have incorporated a higher probability of default related to those loans as they approach their scheduled repricing date in the measurement of our allowance for credit losses. Our allowance for credit losses is determined based on quantitative modeling that incorporates and weighs economic forecast scenarios. The key inputs to our quantitative allowance for credit losses models include borrowers' projected debt service based on the most recent financial information available and underlying collateral property values. Property values are particularly meaningful for our multi-family and commercial real estate portfolios. Our models consider the entire life of the loan, including both the interest only period of the loan, if applicable, and the amortization period, to assess the probability of default and the loss given default. For our multi-family portfolio, we obtain and utilize current and projected geography-specific market information in our forecasts. In estimating the qualitative component of our allowance for credit losses, we have adjusted key inputs used by the model on an average basis for certain loans, most notably net operating income and property values to reflect weaknesses in the underlying data, including the recency of appraisal values, and the lack of significant loss history in available data, particularly for multi-family loans. As of June 30, 2024 and December 31, 2023, the allowance for unfunded commitments totaled $58 million and $52 million, respectively. The allowance for credit losses on loans and leases to total loans held for investment ratio increased to 1.70 percent at June 30, 2024, compared to 1.17 percent at December 31, 2023. Excluding loans with government guarantees and warehouse loans, the allowance for credit losses was 1.72 percent at June 30, 2024, compared to 1.26 percent at December 31, 2023.

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 June 30, 2024 and December 31, 2023, the carrying value of residual assets with third-party residual value insurance for at least a portion of the asset value was $26 million and $280 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: Three Months Ended, Six Months Ended, (in millions) June 30, 2024 June 30, 2023 June 30, 2024 June 30, 2023 Interest income on lease financing (1) $ 35 $ 32 $ 73 $ 52 (1) Included in Interest Income – Loans and leases in the Consolidated Statements of Income and Comprehensive Income. At June 30, 2024 and December 31, 2023, the carrying value of net investment in leases, excluding purchase accounting adjustments was $3.0 billion and $3.5 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) June 30, 2024 December 31, 2023 Net investment in the lease - lease payments receivable $ 2,625 $ 3,187 Net investment in the lease - unguaranteed residual assets 360 321 Total lease payments $ 2,985 $ 3,508 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) June 30, 2024 2024 $ 268 2025 432 2026 703 2027 446 2028 267 Thereafter 869 Total lease payments $ 2,985 Plus: deferred origination costs 28 Less: unearned income (218) Less: purchase accounting adjustment (64) Total lease finance receivables, net $ 2,731 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. Right of use asset 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 right of use 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 right of use 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: Three Months Ended, Six Months Ended, (in millions) June 30, 2024 June 30, 2023 June 30, 2024 June 30, 2023 Operating lease cost $ 20 $ 25 $ 38 $ 35 Total lease cost $ 20 $ 25 $ 38 $ 35 Supplemental cash flow information related to the leases for the following periods: Three Months Ended, Six Months Ended, (in millions) June 30, 2024 June 30, 2023 June 30, 2024 June 30, 2023 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 18 $ 20 $ 36 $ 30 Supplemental balance sheet information related to the leases for the following periods: (in millions, except lease term and discount rate) June 30, 2024 December 31, 2023 Operating Leases: Operating lease right-of-use assets (1) $ 414 $ 426 Operating lease liabilities (2) $ 436 $ 446 Weighted average remaining lease term 10.7 years 11.2 years Weighted average discount rate % 4.71 % 4.71 % (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 mortgage servicing rights that result from the sale of loans to the secondary market for which we retain the servicing. The Company accounts for mortgage servicing rights at fair value. A primary risk associated with mortgage servicing rights 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 mortgage servicing rights 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 mortgage servicing rights risk, see Note 14 - Derivative and Hedging Activities. Subsequent to June 30, 2024, the Company entered into an agreement to sell all of its mortgage servicing rights for an amount equal to their carrying amount at the date of the agreement. See Note 19 - Subsequent Events. Changes in the fair value of residential first mortgage servicing rights ("MSRs") were as follows: Three Months Ended, Six Months Ended, (in millions) June 30, 2024 June 30, 2023 June 30, 2024 June 30, 2023 Balance at beginning of period $ 1,092 $ 1,034 $ 1,111 $ 1,033 Additions from loans sold with servicing retained 58 43 100 81 Reductions from sales — (51) (69) (51) Decrease in MSR fair value due to pay-offs, pay-downs, run-off, model changes, and other (1) (34) (16) (60) (34) Changes in estimates of fair value due to interest rate risk (1) (2) 6 21 40 2 Fair value of MSRs at end of period $ 1,122 $ 1,031 $ 1,122 $ 1,031 (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 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: June 30, 2024 Fair Value (dollars in millions) Actual 10% adverse change 20% adverse change Option adjusted spread 5.2 % $ (20) $ (39) Constant prepayment rate 7.9 % (40) (77) Weighted average cost to service per loan $ 68 $ (11) $ (22) December 31, 2023 Fair Value (dollars in millions) Actual 10% adverse change 20% adverse change Option adjusted spread 5.4 % $ (20) $ (39) Constant prepayment rate 7.9 % (37) (71) Weighted average cost to service per loan $ 69 $ (10) $ (21) 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 mortgage servicing rights, 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.

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 Statements 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 mortgage servicing right 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 loans held for sale is managed using corresponding forward sale commitments and U.S. 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. During the three months ended June 30, 2024 we de-designated and terminated all of our derivatives that were designated in a cash flow or fair value hedge relationship. This action was taken to reduce our asset sensitivity and bring the balance sheet to an interest rate neutral position and did not have any immediate impact to earnings. The remaining impact from the cash flow hedge relationships will be reclassified from other comprehensive income into income over the life of the hedged items. Derivatives designated as hedging instruments . The Company has previously designated certain interest rate swaps as cash flow hedges on overnight Secured Overnight Financing Rates-based variable interest payments on federal home loan bank advances. Changes in the fair value of derivatives previously 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 June 30, 2024, the Company had $88 million (net-of-tax) of unrealized gains on derivatives classified as cash flow hedges recorded in accumulated other comprehensive loss. The Company had $10 million (net-of-tax) of unrealized gains on derivatives classified as cash flow hedges recorded other comprehensive loss at December 31, 2023. 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. 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 previously used 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 involved 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 previously designated and that qualified 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 were recognized in interest income. The fair value basis adjustments remaining from discontinued hedges are recognized in interest income over the remaining life of the hedged items. For the six months ended June 30, 2024, interest income from loans and leases in the accompanying Consolidated Statements of Income and Comprehensive Income was increased by $8 million due to the floating rate payments received on the swaps being greater than the fixed rate payments, as well as the accretion of the fair value basis adjustment subsequent to discontinuance of the hedges. The fair value basis adjustment on our previously 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 $5.9 billion at June 30, 2024, of which unrealized gains of $31 million were due to the discontinued fair value hedge relationship.

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 as of December 31, 2023 were designated as cash flow hedges of certain FHLB borrowings. There were no designated hedging relationships as of June 30, 2024. The following table presents the effect of the Company’s cash flow derivative instruments on accumulated other comprehensive loss: Three Months Ended, Six Months Ended, (in millions) June 30, 2024 June 30, 2023 June 30, 2024 June 30, 2023 Amount of gain (loss) recognized in accumulated other comprehensive loss $ 52 $ 124 $ 143 $ 34 Amount of reclassified from accumulated other comprehensive loss to interest expense $ (16) $ (6) $ (39) $ (12) Amounts reported in accumulated other comprehensive loss 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 U.S. generally accepted accounting principles 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. U.S. generally accepted accounting principles 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, U.S. generally accepted accounting principles 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 June 30, 2024 and December 31, 2023, and that were included in the Company’s Consolidated Statements of Condition at those dates: June 30, 2024 (in millions) Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Total Fair Value Assets: Mortgage-related Debt Securities Available for Sale: GSE certificates $ — $ 1,153 $ — $ 1,153 GSE collateralized mortgage obligations — 7,130 — 7,130 Private label collateralized mortgage obligations — 135 33 168 Total mortgage-related debt securities $ — $ 8,418 $ 33 $ 8,451 Other Debt Securities Available for Sale: GSE debentures $ — $ 1,344 $ — $ 1,344 Asset-backed securities — 269 — 269 Municipal bonds — 6 — 6 Corporate bonds — 341 — 341 Foreign notes — 35 — 35 Capital trust notes — 89 — 89 Total other debt securities $ — $ 2,084 $ — $ 2,084 Total debt securities available for sale $ — $ 10,502 $ 33 $ 10,535 Equity securities: Mutual funds and common stock $ — $ 14 $ — $ 14 Total equity securities $ — $ 14 $ — $ 14 Total securities $ — $ 10,516 $ 33 $ 10,549 Loans held for sale Residential first mortgage loans $ — $ 1,259 $ — $ 1,259 Acquisition, development, and construction — 158 — 158 Commercial and industrial loans — — 34 — 34 Loans held-for-investment Residential first mortgage loans — 68 — 68 Derivative assets Interest rate swaps and swaptions — 111 — 111 Rate lock commitments (fallout-adjusted) — — 9 9 Mortgage-backed securities forwards — 9 — 9 Mortgage servicing rights — — 1,122 1,122 Total assets at fair value $ — $ 12,155 $ 1,164 $ 13,319 Derivative liabilities Mortgage-backed securities forwards $ — $ 9 $ — $ 9 Interest rate swaps and swaptions — 63 — 63 Rate lock commitments (fallout-adjusted) — — 5 5 Total liabilities at fair value $ — $ 72 $ 5 $ 77 December 31, 2023 (in millions) Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Total Fair Value Assets: Mortgage-related Debt Securities Available for Sale: GSE certificates $ — $ 1,221 $ — $ 1,221 GSE collateralized mortgage obligations — 5,162 — 5,162 Private label collateralized mortgage obligations — 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) 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 June 30, 2024 and December 31, 2023: June 30, 2024 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 $ 18,990 $ 18,990 $ 18,990 FHLB and FRB stock (1) 1,565 1,565 — 1,565 Loans and leases held for investment, net 73,284 68,431 — 68,431 Financial Liabilities: Deposits $ 79,032 $ 78,660 $ 50,252 (2) $ 28,408 (3) Borrowed funds 28,892 28,770 28,770 (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. Mortgage Servicing Rights The significant unobservable inputs used in the fair value measurement of the mortgage servicing rights 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 mortgage servicing rights. For June 30, 2024, the weighted average life (in years) for the entire portfolio was 7.09. 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 certificates of deposit 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 June 30, 2024 and December 31, 2023. 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 loans held for sale is accrued on the principal outstanding primarily using the "simple-interest" method.

Dividends accrue on the shares at a fixed rate equal to 6.375 percent per annum until March 17, 2027, and a floating rate equal to three-month Secured Overnight Financing Rate plus 408.26 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. In the second quarter of 2024, we paid dividends on our Series A preferred stock of $15.94 per share. Series B Preferred Stock As of June 30, 2024, each share of Series B Noncumulative Convertible Preferred Stock (the “Series B Preferred Stock”) was automatically convertible into 1,000 shares of our common stock (or one share of Series C Preferred Stock in limited circumstances) in the event of a transfer consistent with the rules and limitations of Regulation Y (a "Reg Y Transfer"). As of June 30, 2024, the issued and outstanding shares of Series B Preferred Stock represented the right (on an as converted basis) to receive approximately 64 million shares of our common stock. Series B Preferred Stock shareholders do not have voting rights, except in limited circumstances. On June 5, 2024, shareholders approved (a) an amendment to the Amended and Restated Certificate of Incorporation of the Company to increase the number of authorized shares of our common stock from 300,000,000 to 666,666,666; and (b) the issuance of shares of our common stock in connection with the March 2024 capital raise pursuant to New York Stock Exchange listing rules (the “Stockholder Approvals”). In accordance with the Series B Preferred Stock Certificate of Designations, upon obtaining the Stockholder Approvals, the quarterly non-cumulative cash dividend (annual rate of 13 percent) and liquidation preference rights ceased to apply. Shares of Series B Preferred Stock (a) are now entitled to receive dividends at the same time and on the same terms as the holders of common stock, including for the dividend declared and paid by the Company on June 17, 2024, and (b) rank as equal to the Common Stock in any liquidation of the Company. The Series B Preferred Stock is classified in mezzanine equity as it is contingently convertible into shares of preferred stock that are redeemable for cash, contingent on events that are not solely in the control of the Company. The Series B Preferred Stock is not remeasured because it is currently not probable that it will become redeemable. Series C Preferred Stock All of the issued and outstanding shares of the Company's Series C Noncumulative Convertible Preferred Stock (“Series C Preferred Stock”) have converted into shares of common stock in accordance with the terms of the Series C Certificate of Designation as of June 30, 2024. Warrants Warrants to purchase shares of a new class of non-voting, common-equivalent preferred stock of the Company, par value $0.01 per share (the "Series D NVCE Stock") for an initial exercise price of $2,500 per share were issued in conjunction with the March 2024 capital raise. The warrants are not exercisable until September 10, 2024 and expire 7 years after issuance. Pursuant to the terms of the Warrant, as a result of the dividend paid on shares of our common stock on June 17, 2024, the exercise price of the Warrants was reduced to $2,492. The terms of the Warrants prescribe net settlement in shares. All the Warrants issued and outstanding as of June 30, 2024 entitled the holders thereof to receive 315,000 shares of Series D NVCE Stock (subject to net settlement of shares). As of June 30, 2024, no shares of Series D Non-Voting Common Equivalent Stock of the Company (“Series D NVCE Stock”) have been issued. Shares of Series D NVCE Stock are issuable upon the exercise of the Warrant.

Subsequent Events [Abstract]
Subsequent Events	Note 19 - Subsequent Events On July 11, 2024, a previously announced reverse stock split of the Company's issued and outstanding shares of common stock at a ratio of 1-for-3 took effect. On the effective date, every three shares of common stock issued and outstanding or held by the Company in treasury were combined into one issued share of common stock. In addition, the aggregate number of equity-based awards that remain available to be granted under the Company’s equity compensation plans was decreased proportionately and proportionate adjustments were made to the per share exercise price, share-based vesting criteria and the number of shares issuable upon the exercise of outstanding stock options, as applicable, as well as to the number of shares that would be owned upon vesting and settlement of restricted stock units and other equity-based awards, as applicable. The impact of the reverse stock split on the Company's preferred stock and warrants is discussed within Note 17 - Mezzanine and Stockholders' Equity. No fractional shares were issued as a result of the reverse stock split. In accordance with ASC 260-10-55-12, the Company has adjusted the number of shares, per-share computations and the computations of basic and diluted EPS retroactively for all periods presented in the financial statements and related notes. On July 22, 2024 the Company announced that it had closed on the sale of approximately $6 billion of mortgage warehouse loans to JP Morgan Chase Bank, N.A. The Company expects to close on an additional $200 million of mortgage warehouse loans in the near future, once necessary customer approvals are received. We expect to recognize certain expenses associated with the mortgage warehouse sale in the third quarter. On July 25, 2024, the Company announced that it had entered into a definitive agreement to sell its residential mortgage servicing business, including mortgage servicing rights and third-party origination platform, to Mr. Cooper, a leading mortgage originator and servicer, for approximately $1.4 billion. The transaction is expected to close during the fourth quarter of 2024.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The accompanying financial statements of the Company and other entities in which the Company has a controlling financial interest, have been prepared using U.S. generally accepted accounting principles for interim financial statements. The accompanying financial statements of the Company conform to U.S. generally accepted accounting principles and to general practices within the banking industry. The preparation of financial statements in conformity with U.S. generally accepted accounting principles 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 and the acquisition method of accounting.
Consolidation	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.

It also includes certain other amendments to improve the effectiveness of income tax disclosures. The guidance should be applied on a prospective or retrospective basis. We are in the process of assessing the impact of the adoption of this ASU on the consolidated financial statements and disclosures. January 1, 2025 Early adoption is permitted. ASU 2024-01, Compensation—Stock Compensation (Topic 718): Scope Application for Profits Interest and Similar Awards This guidance provides the addition of illustrative examples clarifying the accounting for profits interest and similar awards.

January 1, 2025 Early adoption is permitted.
Earnings per Common Share (Basic and Diluted)	Basic earnings per share is computed by dividing the net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed using the same method as basic earnings per share, however, the computation reflects the potential dilution that would occur if outstanding in-the-money stock options were exercised and converted into common stock. Diluted earnings per share is the amount of earnings available to each common share outstanding during the reporting periods adjusted to include the effects of potentially dilutive common shares. Potentially dilutive common shares include warrants, convertible preferred stock, stock options and other stock-based awards. Potentially dilutive common shares are excluded from the computation of diluted earnings per share in the periods where the effect would be antidilutive. As the average common share price was above the $7.50 per share exercise price (on an as-converted common stock basis) of the warrants, the corresponding 105 million common shares underlying the shares of non-voting, common-equivalent preferred stock of the Company, par value $0.01 per share (the "Series D NVCE Stock"), underlying such warrants would have been included in the dilutive share count if the Company had positive earnings for the period (reflective of the reverse stock split discussed in Note 19 - Subsequent Events).
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 other assets and other liabilities in the Consolidated Statements of Condition. Right of use asset 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 right of use 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 right of use 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	U.S. generally accepted accounting principles 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. U.S. generally accepted accounting principles 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, U.S. generally accepted accounting principles 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.
Business Combinations	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.
