Organization and Basis of Presentation	Mar. 31, 2018
Organization and Basis of Presentation	Note 1. 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) was organized under Delaware law on July 20, 1993 and is the holding company for New York Community Bank and New York Commercial Bank (hereinafter referred to as the Community Bank and the Commercial Bank, respectively, and collectively as the Banks). For the purpose of these Consolidated Financial Statements, the Community Bank and the Commercial Bank refer not only to the respective banks but also to their respective subsidiaries. The Community Bank is the primary banking subsidiary of the Company, which was formerly known as Queens County Bancorp, Inc. Founded on April 14, 1859 and formerly known as Queens County Savings Bank, the Community Bank converted from a state-chartered mutual savings bank to the capital stock form of ownership on November 23, 1993, at which date 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 Commercial Bank was established on December 30, 2005. Reflecting its growth through acquisitions, the Community Bank currently operates 225 branches, two of which operate directly under the Community Bank name. The remaining 223 Community Bank branches operate through seven divisional banks: Queens County Savings Bank, Roslyn Savings Bank, Richmond County Savings Bank, and Roosevelt Savings Bank in New York; Garden State Community Bank in New Jersey; AmTrust Bank in Florida and Arizona; and Ohio Savings Bank in Ohio. The Commercial Bank currently operates 30 branches in Manhattan, Queens, Brooklyn, Westchester County, and Long Island (all in New York), including 18 branches that operate under the Atlantic Bank name. 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 GAAP 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 that are particularly susceptible to change in the near term are used in connection with the determination of the allowances for loan losses; the evaluation of goodwill for impairment; and the evaluation of the need for a valuation allowance on the Company’s deferred tax assets. 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 7, Borrowed Funds, for additional information regarding these trusts.

However, even if an investor does not expect to sell a debt security, it must evaluate the expected cash flows to be received and determine if a credit loss has occurred. In the event that a credit loss occurs, only the amount of impairment associated with the credit loss is recognized in earnings. Amounts of impairment relating to factors other than credit losses are recorded in AOCL. At March 31, 2018, the Company had unrealized losses on certain GSE obligations, U.S. Treasury obligations, municipal bonds, capital trust notes, and equity securities. The unrealized losses on the Company’s GSE obligations, U.S. Treasury obligations, municipal bonds, and capital trust notes at March 31, 2018 were primarily caused by movements in market interest rates and spread volatility, rather than credit risk. These securities are not expected to be settled at a price that is less than the amortized cost of the Company’s investment. The Company reviews quarterly financial information related to its investments in capital trust notes, as well as other information that is released by each of the issuers of such notes, to determine their continued creditworthiness. The Company continues to monitor these investments and currently estimates that the present value of expected cash flows is not less than the amortized cost of the securities. It is possible that these securities will perform worse than is currently expected, which could lead to adverse changes in cash flows from these securities and potential OTTI losses in the future. Future events that could trigger material unrecoverable declines in the fair values of the Company’s investments, and thus result in potential OTTI losses, include, but are not limited to, government intervention; deteriorating asset quality and credit metrics; significantly higher levels of default and loan loss provisions; losses in value on the underlying collateral; net operating losses; and illiquidity in the financial markets. The Company considers a decline in the fair value of equity securities to be other than temporary if the Company does not expect to recover the entire amortized cost basis of the security. The unrealized losses on the Company’s equity securities at March 31, 2018 were caused by market volatility. The Company evaluated the near-term prospects of recovering the fair value of these securities, together with the severity and duration of impairment to date, and determined that they were not other-than-temporarily impaired. Nonetheless, it is possible that these equity securities will perform worse than is currently expected, which could lead to adverse changes in their fair value, or to the failure of the securities to fully recover in value as currently anticipated by management. Either event could cause the Company to record an OTTI loss in a future period. Events that could trigger a material decline in the fair value of these securities include, but are not limited to, deterioration in the equity markets; a decline in the quality of the loan portfolio of the issuer in which the Company has invested; and the recording of higher loan loss provisions and net operating losses by such issuer. The investment securities designated as having a continuous loss position for twelve months or more at both March 31, 2018 and December 31, 2017 consisted of six agency mortgage-related securities, five capital trust notes, two municipal bonds, and one mutual fund. At March 31, 2018, the fair value of securities having a continuous loss position for twelve months or more was 7.8% below the collective amortized cost of $117.9 million. At December 31, 2017, the fair value of such securities was 8.5% below the collective amortized cost of $118.2 million. At March 31, 2018 and December 31, 2017, the combined market value of the respective securities represented unrealized losses of $9.2 million and $10.1 million, respectively.

Loans Loans Held for Investment The majority of the loans the Company originates for investment are multi-family loans, most of which are collateralized by non-luxury mixed-use To a lesser extent, the Company also originates one-to-four One-to-four ADC loans are primarily originated for multi-family and residential tract projects in New York City and on Long Island. C&I loans consist of asset-based loans, equipment loans and leases, and dealer floor-plan loans (together, specialty finance loans and leases) that generally are 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; and other C&I loans that primarily are made to small and mid-size The repayment of multi-family and CRE loans generally depends on the income produced by the underlying properties which, in turn, depends on their successful operation and management. To mitigate the potential for credit losses, the Company underwrites its loans in accordance with credit standards it considers to be prudent, looking first at the consistency of the cash flows being produced by the underlying property. In addition, multi-family buildings, CRE properties, and ADC projects are inspected as a prerequisite to approval, and independent appraisers, whose appraisals are carefully reviewed by the Company’s in-house To further manage its credit risk, the Company’s lending policies limit the amount of credit granted to any one borrower and typically require conservative debt service coverage ratios and loan-to-value ADC loans typically involve a higher degree of credit risk than loans secured by improved or owner-occupied real estate. Accordingly, borrowers are required to provide a guarantee of repayment and completion, and loan proceeds are disbursed as construction progresses, as certified by in-house To minimize the risk involved in specialty finance lending and leasing, the Company participates in syndicated loans that are brought to it, and equipment loans and leases that are assigned to it, by a select group of nationally recognized sources who have had long-term relationships with its experienced lending officers. Each of these credits is secured with a perfected first security interest or outright ownership in the underlying collateral, and structured as senior debt or as a non-cancelable re-underwritten. To minimize the risks involved in other C&I lending, the Company underwrites such loans on the basis of the cash flows produced by the business; requires that such loans be collateralized by various business assets, including inventory, equipment, and accounts receivable, among others; and typically requires personal guarantees. However, the capacity of a borrower to repay such a C&I loan is substantially dependent on the degree to which the business is successful. In addition, the collateral underlying such loans may depreciate over time, may not be conducive to appraisal, or may fluctuate in value, based upon the results of operations of the business.

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 Troubled Debt Restructurings The Company is required to account for certain held-for-investment non-accrual 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.

The Company does not consider a payment to be in default when the loan is in forbearance, or otherwise granted a delay of payment, when the agreement to forebear or allow a delay of payment is part of a modification. Subsequent to the modification, the loan is not considered to be in default until payment is contractually past due in accordance with the modified terms. However, the Company does consider a loan with multiple modifications or forbearance periods to be in default, and would also consider a loan to be in default if the borrower were in bankruptcy or if the loan were partially charged off subsequent to modification.

Fair Value Measurements

Fair Value Measurements	Mar. 31, 2018
Fair Value Measurements	Note 10. 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 • 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 March 31, 2018 and December 31, 2017, and that were included in the Company’s Consolidated Statements of Condition at those dates: Fair Value Measurements at March 31, 2018 (in thousands) Quoted Prices Significant Significant Netting (1) Total Assets: Mortgage-Related Securities Available for Sale: GSE certificates $ — $ 1,971,177 $ — $ — $ 1,971,177 GSE CMOs — 541,587 — — 541,587 Total mortgage-related securities $ — $ 2,512,764 $ — $ — $ 2,512,764 Other 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. The Company carries loans held for sale at fair value. The fair value of loans held for sale is based on an exit price, representing the amount that would be received when selling an asset in an orderly transaction between market participants. Loans held for sale are classified within Level 2 of the valuation hierarchy. MSRs do not trade in an active open market with readily observable prices. The Company bases the fair value of its MSRs on the present value of estimated future net servicing income cash flows, utilizing a third-party valuation specialist. The specialist estimates future net servicing income cash flows with assumptions that market participants would use to estimate fair value, including estimates of prepayment speeds, discount rates, default rates, refinance rates, servicing costs, escrow account earnings, contractual servicing fee income, and ancillary income. The Company periodically adjusts the underlying inputs and assumptions to reflect market conditions and assumptions that a market participant would consider in valuing the MSR asset. MSR fair value measurements use significant unobservable inputs and, accordingly, are classified within Level 3. 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 Option Loans Held for Sale The Company has elected the fair value option for its loans held for sale. These loans held for sale consist of one-to-four The following table reflects the difference between the fair value carrying amount of loans held for sale, for which the Company has elected the fair value option, and the unpaid principal balance: March 31, 2018 December 31, 2017 (in thousands) Fair Value Aggregate Fair Value Fair Value Aggregate Fair Value Loans held for sale $ 31,402 $ 36,498 $ (5,096 ) $ 35,258 $ 34,563 $ 695 Gains and Losses Included in Income for Assets Where the Fair Value Option Has Been Elected The assets accounted for under the fair value option are initially measured at fair value. Gains and losses from the initial measurement and subsequent changes in fair value are recognized in earnings. The following table presents the changes in fair value related to initial measurement, and the subsequent changes in fair value included in earnings, for MSRs for the periods indicated: (Loss) Gain Included in Income from Changes in Fair Value (1) For the Three Months Ended March 31, (in thousands) 2018 2017 Mortgage servicing rights $ (154 ) $ (2,789 ) (1) Included in “Non-interest Changes in Level 3 Fair Value Measurements The following tables present, for the three months ended March 31, 2018 and March 31, 2017, a roll-forward of the balance sheet amounts (including changes in fair value) for financial instruments classified in Level 3 of the valuation hierarchy: (in thousands) Fair Value Total Realized/Unrealized Issuances Settlements Transfers Fair Value Change in Income/ Comprehensive Mortgage servicing rights $ 2,729 $ (154 ) $ — $ — $ — $ — $ 2,575 $ (154 ) (in thousands) Fair Value Total Realized/Unrealized Issuances Settlements Transfers Fair Value Change in Income/ Comprehensive Mortgage servicing rights $ 228,099 $ (2,726 ) $ — $ 7,574 $ (4,147 ) $ — $ 228,800 $ (2,726 ) Interest rate lock commitments 982 1,467 — — — — 2,449 2,430 The Company’s policy is to recognize transfers in and out of Levels 1, 2, and 3 as of the end of the reporting period. There were no transfers in or out of Levels 1, 2, or 3 during the three months ended March 31, 2018 or 2017. For Level 3 assets and liabilities measured at fair value on a recurring basis as of March 31, 2018, the significant unobservable inputs used in the fair value measurements were as follows: (dollars in thousands) Fair Value at Valuation Technique Significant Unobservable Inputs Significant Mortgage servicing rights $2,575 Discounted Cash Flow Weighted Average Constant Prepayment Rate (1) 10.66 % Weighted Average Discount Rate 12.00 (1) Represents annualized loan repayment rate assumptions. The significant unobservable inputs used in the fair value measurement of the Company’s MSRs are the weighted average constant prepayment rate and the weighted average discount rate. Significant increases or decreases in either of those inputs in isolation could result in significantly lower or higher fair value measurements. Although the constant prepayment rate and the discount rate are not directly interrelated, they generally move in opposite directions.

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- off-balance 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 March 31, 2018 and December 31, 2017: March 31, 2018 Fair Value Measurement Using (in thousands) Carrying Value Estimated Quoted Prices in Significant Significant Financial Assets: Cash and cash equivalents $ 2,680,772 $ 2,680,772 $ 2,680,772 $ — $ — FHLB stock (1) 622,989 622,989 — 622,989 — Loans, net 38,759,685 38,462,422 — — 38,462,422 Financial Liabilities: Deposits $ 29,235,434 $ 29,178,221 $ 20,172,114 (2) $ 9,006,107 (3) $ — Borrowed funds 13,343,759 13,176,141 — 13,176,141 — (1) Carrying value and estimated fair value are at cost.

(2) Interest-bearing checking and money market accounts, savings accounts, and non-interest-bearing (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. Prior to adopting ASU No. 2016-01, non-performing Mortgage Servicing Rights MSRs do not trade in an active market with readily observable prices. Accordingly, the Company bases the fair value of its MSRs on a valuation performed by a third-party valuation specialist. This specialist determines fair value based on the present value of estimated future net servicing income cash flows, and incorporates assumptions that market participants would use to estimate fair value, including estimates of prepayment speeds, discount rates, default rates, refinance rates, servicing costs, escrow account earnings, contractual servicing fee income, and ancillary income. The specialist and the Company evaluate, and periodically adjust, as necessary, these underlying inputs and assumptions to reflect market conditions and changes in the assumptions that a market participant would consider in valuing MSRs. 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 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 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

ASU No. 2016-02 is intended to improve financial reporting about leasing transactions and the key provision impacting the Company is the requirement for a lessee to record a right-of-use asset and a liability, which represents the obligation to make lease payments for long-term operating leases. Additionally, the ASU includes quantitative and qualitative disclosures required by lessees and lessors to help financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases. Lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. The Company’s working group, comprised of associates from disciplines such as Vendor Risk Management, Real Estate, Technology, and Accounting, have made substantial progress in reviewing contractual arrangements for embedded leases in an effort to identify the Company’s full lease population. To date, we have found only a few minor embedded leases in our non-lease contracts. We are presently evaluating all of our leases for compliance with the new lease accounting rules and as a lessor and lessee, we do not anticipate the classification of our leases to change. However, the Company’s assets and liabilities will increase based on the present value of remaining lease payments for leases in place at the adoption date. The Company is currently reviewing vendor software solutions to provide a robust lease accounting package that will accurately prepare the financial statement adjustments and enhanced disclosures required by ASU No. 2016-02.

Organization and Basis of Presentation (Policies)	3 Months Ended
Organization and Basis of Presentation (Policies)	Mar. 31, 2018
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 GAAP 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 that are particularly susceptible to change in the near term are used in connection with the determination of the allowances for loan losses; the evaluation of goodwill for impairment; and the evaluation of the need for a valuation allowance on the Company’s deferred tax assets. 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 7, Borrowed Funds, for additional information regarding these trusts.
