Organization, Basis of Presentation, and Impact of Recent Accounting Pronouncements	Note 1. Organization, Basis of Presentation, and Impact of Recent Accounting Pronouncements 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 (hereinafter referred to as the “Bank”). Founded on April 14, 1859 and formerly known as Queens County Savings Bank, the 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 Bank currently operates 237 branches, 18 of which operate directly under the New York Community Bank name. The remaining 219 Community Bank branches operate through eight divisional banks: Queens County Savings Bank, Roslyn Savings Bank, Richmond County Savings Bank, Roosevelt Savings Bank, and Atlantic Bank in New York; Garden State Community Bank in New Jersey; AmTrust Bank in Florida and Arizona; and Ohio Savings Bank in Ohio. Basis of Presentation The following is a description of the significant accounting and reporting policies that the Company and its subsidiaries follow in preparing and presenting their consolidated financial statements, which conform to U.S. generally accepted accounting principles (“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 allowance for credit losses and the evaluation of goodwill for impairment. 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. Impact of Recent Accounting Pronouncements Recently Adopted Accounting Standards The Company adopted ASU No. 2022-01—Derivatives and Hedging (Topic 815): Fair Value Hedging-Portfolio Layer Method in the first quarter of 2022 upon issuance. The amendments expand the current last-of-layer method of hedge accounting that permits only one hedged layer to allow multiple hedged layers of a single closed portfolio. To reflect that expansion, the last-of-layer method is renamed the portfolio layer method. In addition, the amendments expand the scope of the portfolio layer method to include non-prepayable assets; specify eligible hedging instruments in a single-layer hedge; provide additional guidance on the accounting for and disclosure of hedge basis adjustments; specify how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio. To date, the guidance has not had any impact on the Company’s Consolidated Statements of Condition, results of operations, or cash flows.
