Basis of Presentation The Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the SEC and in conformity with U.S. GAAP. The Company’s Consolidated Financial Statements include the Company’s accounts and all subsidiaries in which the Company has a controlling interest. Intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications have been made to previously reported amounts to conform to the current presentation. On November 1, 2021, the Company completed the Insurance Business Disposition (see Note 5—"Divestitures" for additional information). On July 30, 2021, the Company completed the purchase of the Futures Exchange Group for a purchase price of $4.9 million at closing, plus the cash held at closing by the Futures Exchange Group, and an earn-out, only payable out of the Company's portion of the profits of the Futures Exchange Group, capped at the amount Cantor contributed to the Futures Exchange Group prior to closing. The Futures Exchange Group acquisition has been determined to be a combination of entities under common control that resulted in a change in the reporting entity. Accordingly, the financial results of the Company have been recast to include the financial results of the Futures Exchange Group in the current and prior periods as if the Futures Exchange Group had always been consolidated. The assets and liabilities of the Futures Exchange Group have been recorded in the Company's Consolidated Statements of Financial Condition at the seller's historical carrying value. The purchase of the Futures Exchange Group was accounted for as an equity transaction for the period ended September 30, 2021 (the period in which the transaction occurred). During the first quarter of 2022, the Company changed the name of the brokerage product line formerly labeled as “Equity derivatives and cash equity” to “Equities” to better align the caption with the underlying activity. The change did not result in any reclassification of revenues and had no impact on the Company’s Total brokerage revenues. During the second quarter of 2022, the Company combined "Realized losses (gains) on marketable securities", "Unrealized losses (gains) on marketable securities", and "Losses (gains) on other investments" on the unaudited Condensed Consolidated Statements of Cash Flows into "Losses (gains) on marketable securities and other investments". The recognition of gains and losses related to these investments are similar in nature and immaterial to the financial statements in 2022 and 2021. During the third quarter of 2022, the Company renamed "Securities owned" as "Financial instruments owned, at fair value" and combined it with "Marketable securities" on the unaudited Condensed Consolidated Statements of Financial Condition. In addition, "Losses (gains) on marketable securities and other investments" was renamed as "Unrealized/realized losses (gains) on financial instruments owned, at fair value and other investments" on the unaudited Condensed Consolidated Statements of Cash Flows. The Consolidated Financial Statements contain all normal and recurring adjustments that, in the opinion of management, are necessary for a fair presentation of the Consolidated Statements of Financial Condition, the Consolidated Statements of Operations, the Consolidated Statements of Comprehensive Income (Loss), the Consolidated Statements of Cash Flows and the Consolidated Statements of Changes in Equity of the Company for the periods presented. Spin-Off of Newmark On November 30, 2018, the Company completed the Spin-Off. See Note 2—"Limited Partnership Interests in BGC Holdings and Newmark Holdings," and Note 13—"Related Party Transactions" for more information. Recently Adopted Accounting Pronouncements In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes . The ASU is part of the FASB’s simplification initiative, and it is expected to reduce cost and complexity related to accounting for income taxes by eliminating certain exceptions to the guidance in ASC 740, Income Taxes related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The guidance also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates, and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. BGC adopted the standard on the required effective date beginning January 1, 2021 on a prospective basis. The adoption of the standard did not have a material impact on the Company’s Consolidated Financial Statements. In January 2020, the FASB issued ASU No. 2020-01, Investments—Equity Securities (Topic 321) , Investments—Equity Method and Joint Ventures (Topic 323) , and Derivatives and Hedging (Topic 815)—Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (a consensus of the FASB Emerging Issues Task Force) . These amendments improve previous guidance by reducing diversity in practice and increasing comparability of the accounting for the interactions between these codification topics as they pertain to certain equity securities, investments under the equity method of accounting and forward contracts or purchased options to purchase securities that, upon settlement of the forward contract or exercise of the purchased option, would be accounted for under the equity method of accounting or the fair value option. BGC adopted the standard on the required effective date beginning January 1, 2021 on a prospective basis. The adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements. In October 2020, the FASB issued ASU No. 2020-10, Codification Improvements . The standard amends the Codification by moving existing disclosure requirements to (or adding appropriate references in) the relevant disclosure sections. The ASU also clarifies various provisions of the Codification by amending and adding new headings, cross-referencing, and refining or correcting terminology. BGC adopted the standard on the required effective date beginning January 1, 2021 and it was applied using a modified retrospective method of transition. The adoption of this guidance did not have an impact on the Company’s Consolidated Financial Statements. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . The guidance is designed to provide relief from the accounting analysis and impacts that may otherwise be required for modifications to agreements (e.g., loans, debt securities, derivatives, and borrowings) necessitated by reference rate reform as entities transition away from LIBOR and other interbank offered rates to alternative reference rates. This ASU also provides optional expedients to enable companies to continue to apply hedge accounting to certain hedging relationships impacted by reference rate reform. Application of the guidance is optional and only available in certain situations. The ASU is effective upon issuance and generally can be applied through December 31, 2022. In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848): Scope . The amendments in this standard are elective and principally apply to entities that have derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform (referred to as the “discounting transition”). The standard expands the scope of ASC 848, Reference Rate Reform and allows entities to elect optional expedients to derivative contracts impacted by the discounting transition. Similar to ASU No. 2020-04, provisions of this ASU are effective upon issuance and generally can be applied through December 31, 2022. During the first quarter of 2022, the Company elected to apply the practical expedients to modifications of qualifying contracts as continuation of the existing contract rather than as a new contract. The adoption of the new guidance did not have an impact on the Company's Consolidated Financial Statements. In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity . The standard is expected to reduce complexity and improve comparability of financial reporting associated with accounting for convertible instruments and contracts in an entity’s own equity. The ASU also enhances information transparency by making targeted improvements to the related disclosures guidance. Additionally, the amendments affect the diluted EPS calculation for instruments that may be settled in cash or shares and for convertible instruments. BGC adopted the standard on the required effective date beginning January 1, 2022, and it was applied using a modified retrospective method of transition. The adoption of this guidance did not have a material impact on the Company's Consolidated Financial Statements. In November 2021, the FASB issued ASU No. 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance . The standard requires business entities to make annual disclosures about transactions with a government they account for by analogizing to a grant or contribution accounting model. The guidance is aimed at increasing transparency about government assistance transactions that are not in the scope of other U.S. GAAP guidance. The ASU requires disclosure of the nature and significant terms and considerations of the transactions, the accounting policies used and the effects of those transactions on an entity’s financial statements. The new standard became effective for the Company’s financial statements issued for annual reporting periods beginning on January 1, 2022, and it will be applied prospectively. The adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements. New Accounting Pronouncements In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers . The standard improves the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to the recognition of an acquired contract liability, as well as payment terms and their effect on subsequent revenue recognized by the acquirer. The ASU requires companies to apply guidance in ASC 606, Revenue from Contracts with Customers , to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination, and, thus, creates an exception to the general recognition and measurement principle in ASC 805, Business Combinations . The new standard became effective for the Company beginning January 1, 2023, and will be applied prospectively for business combinations occurring on or after the effective date. The adoption of this guidance is not expected to have a material impact on the Company’s Consolidated Financial Statements. In March 2022, the FASB issued ASU No. 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . The guidance is intended to improve the decision usefulness of information provided to investors about certain loan refinancings, restructurings, and write-offs. The standard eliminates the recognition and measurement guidance on TDRs for creditors that have adopted ASC 326, Financial Instruments — Credit Losses and requires them to make enhanced disclosures about loan modifications for borrowers experiencing financial difficulty. The new guidance also requires public business entities to present current-period gross write-offs (on a current year-to-date basis for interim-period disclosures) by year of origination in their vintage disclosures. The new standard became effective for the Company beginning January 1, 2023. The guidance for recognition and measurement of TDRs will be applied using a prospective transition method, and the amendments related to disclosures will be applied prospectively. The adoption of this guidance is not expected to have a material impact on the Company’s Consolidated Financial Statements. In September 2022, the FASB issued ASU No. 2022-04, Liabilities—Supplier Finance Programs (Subtopic 405-50): Debt Restructurings Disclosure of Supplier Finance Program Obligations . The guidance requires entities to disclose the key terms of supplier finance programs they use in connection with the purchase of goods and services along with information about their obligations under these programs, including a rollforward of those obligations. The new standard became effective for the Company beginning on January 1, 2023, except for the rollforward requirement, which is effective beginning January 1, 2024. The guidance requires retrospective application to all periods in which a balance sheet is presented, except for the rollforward requirement, which will be applied prospectively. The adoption of this guidance is not expected to have a material impact on the Company’s Consolidated Financial Statements. In December 2022, the FASB issued ASU No. 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848. ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting provided optional guidance to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The ASU was effective upon issuance and generally could be applied through December 31, 2022. Because the current relief in ASC 848, Reference Rate Reform may not cover a period of time during which a significant number of modifications may take place, the amendments in ASU No. 2022-06 defer the sunset date from December 31, 2022 to December 31, 2024, after which entities will no longer be permitted to apply the relief in ASC 848. The ASU is effective upon issuance. Management is currently evaluating the impact of the new standard on the Company’s consolidated financial statements.

Limited Partnership Interests i

Limited Partnership Interests in BGC Holdings and Newmark Holdings	12 Months Ended
	Dec. 31, 2022
Equity [Abstract]
Limited Partnership Interests in BGC Holdings and Newmark Holdings	Limited Partnership Interests in BGC Holdings and Newmark Holdings BGC Partners is a holding company with no direct operations and conducts substantially all of its operations through its operating subsidiaries. Virtually all of the Company’s consolidated net assets and net income are those of consolidated variable interest entities. BGC Holdings is a consolidated subsidiary of the Company for which the Company is the general partner. The Company and BGC Holdings jointly own BGC U.S. OpCo and BGC Global OpCo, the two operating partnerships. In addition, Newmark Holdings is a consolidated subsidiary of Newmark for which Newmark is the general partner. Newmark and Newmark Holdings jointly own Newmark OpCo, the operating partnership. Listed below are the limited partnership interests in BGC Holdings and Newmark Holdings. The FPUs, LPUs and limited partnership interests held by Cantor, each as described below, collectively represent all of the limited partnership interests in BGC Holdings and Newmark Holdings. As a result of the Separation, limited partnership interests in Newmark Holdings were distributed to the holders of limited partnership interests in BGC Holdings, whereby each holder of BGC Holdings limited partnership interests at that time who held a BGC Holdings limited partnership interest received a corresponding Newmark Holdings limited partnership interest, determined by the Contribution Ratio, which was equal to a BGC Holdings limited partnership interest multiplied by one divided by 2.2, divided by the Exchange Ratio. Initially, the Exchange Ratio equaled one, so that each Newmark Holdings limited partnership interest was exchangeable for one share of Newmark Class A common stock. For reinvestment, acquisition or other purposes, Newmark may determine on a quarterly basis to distribute to its stockholders a smaller percentage than Newmark Holdings distributes to its equity holders (excluding tax distributions from Newmark Holdings) of cash that it received from Newmark OpCo. In such circumstances, the Separation and Distribution Agreement provides that the Exchange Ratio will be reduced to reflect the amount of additional cash retained by Newmark as a result of the distribution of such smaller percentage, after the payment of taxes. The Exchange Ratio as of December 31, 2022 equaled 0.9303. Founding/Working Partner Units Founding/Working Partners have FPUs in BGC Holdings and Newmark Holdings. The Company accounts for FPUs outside of permanent capital, as “Redeemable partnership interest,” in the Company’s Consolidated Statements of Financial Condition. This classification is applicable to Founding/Working Partner units because these units are redeemable upon termination of a partner, including a termination of employment, which can be at the option of the partner and not within the control of the issuer. FPUs are held by limited partners who are employees and generally receive quarterly allocations of net income. Upon termination of employment or otherwise ceasing to provide substantive services, the FPUs are generally redeemed, and the unit holders are no longer entitled to participate in the quarterly allocations of net income. Since these allocations of net income are cash distributed on a quarterly basis and are contingent upon services being provided by the unit holder, they are reflected as a component of compensation expense under “Equity-based compensation and allocations of net income to limited partnership units and FPUs” in the Company’s Consolidated Statements of Operations. Limited Partnership Units Certain BGC employees hold LPUs in BGC Holdings and Newmark Holdings (e.g., REUs, RPUs, PSUs, and PSIs). Prior to the Separation, certain employees of both BGC and Newmark received LPUs in BGC Holdings. As a result of the Separation, these employees were distributed LPUs in Newmark Holdings equal to a BGC Holdings LPU multiplied by the Contribution Ratio. Subsequent to the Separation, BGC employees are only granted LPUs in BGC Holdings, and Newmark employees are only granted LPUs in Newmark Holdings. Generally, LPUs receive quarterly allocations of net income, which are cash distributed and generally are contingent upon services being provided by the unit holder. As prescribed in U.S. GAAP guidance, following the Spin-Off, the quarterly allocations of net income on BGC Holdings and Newmark Holdings LPUs held by BGC employees are reflected as a component of compensation expense under “Equity-based compensation and allocations of net income to limited partnership units and FPUs” in the Company’s Consolidated Statements of Operations, and the quarterly allocations of net income on BGC Holdings LPUs held by Newmark employees are reflected as a component of “Net income (loss) attributable to noncontrolling interest in subsidiaries” in the Company’s Consolidated Statements of Operations. From time to time, the Company also issues BGC LPUs as part of the consideration for acquisitions. Certain of these LPUs in BGC Holdings and Newmark Holdings, such as REUs, entitle the holders to receive post-termination payments equal to the notional amount of the units in four equal yearly installments after the holder’s termination. These LPUs held by BGC employees are accounted for as post-termination liability awards, and in accordance with U.S. GAAP guidance, the Company records compensation expense for the awards based on the change in value at each reporting date in the Company’s Consolidated Statements of Operations as part of “Equity-based compensation and allocations of net income to limited partnership units and FPUs”. The Company has also awarded certain Preferred Units. Each quarter, the net profits of BGC Holdings and Newmark Holdings are allocated to such units at a rate of either 0.6875% (which is 2.75% per calendar year) or such other amount as set forth in the award documentation. These allocations are deducted before the calculation and distribution of the quarterly partnership distribution for the remaining partnership interests and are generally contingent upon services being provided by the unit holder. The Preferred Units are not entitled to participate in partnership distributions other than with respect to the Preferred Distribution. Preferred Units may not be made exchangeable into Class A common stock, and are only entitled to the Preferred Distribution; accordingly, they are not included in the fully diluted share count. The quarterly allocations of net income on Preferred Units are reflected the same as those of the LPUs described above in the Company’s Consolidated Statements of Operations. After deduction of the Preferred Distribution, the remaining partnership units generally receive quarterly allocations of net income based on their weighted-average pro rata share of economic ownership of the operating subsidiaries. Preferred Units are granted in connection with the grant of certain LPUs, such as PSUs, which may be granted exchangeability or redeemed in connection with the issuance of shares of common stock to cover the withholding taxes owed by the unit holder, rather than issuing the gross amount of shares to employees, subject to cashless withholding of shares to pay applicable withholding taxes. Cantor Units Cantor holds limited partnership interests in BGC Holdings. Cantor units are reflected as a component of “Noncontrolling interest in subsidiaries” in the Company’s Consolidated Statements of Financial Condition. Cantor receives allocations of net income (loss), which are cash distributed on a quarterly basis and are reflected as a component of “Net income (loss) attributable to noncontrolling interest in subsidiaries” in the Company’s Consolidated Statements of Operations. Cantor units in BGC Holdings are generally exchangeable for up to 23.6 million shares of BGC Class B common stock. General Certain of the limited partnership interests, described above, have been granted exchangeability into shares of BGC or Newmark Class A common stock, and additional limited partnership interests may become exchangeable into shares of BGC or Newmark Class A common stock. In addition, certain limited partnership interests have been granted the right to exchange into or have been exchanged into a partnership unit with a capital account, such as HDUs. HDUs have a stated capital account which is initially based on the closing trading price of Class A common stock at the time the HDU is granted. HDUs participate in quarterly partnership distributions and are generally not exchangeable into shares of Class A common stock. Subsequent to the Spin-Off, limited partnership interests in BGC Holdings held by a partner or Cantor may become exchangeable for BGC Class A or BGC Class B common stock on a one-for-one basis, and limited partnership interests in Newmark Holdings held by a partner or Cantor may become exchangeable for a number of shares of Newmark Class A or Newmark Class B common stock equal to the number of limited partnership interests multiplied by the then-current Exchange Ratio. Because limited partnership interests are included in the Company’s fully diluted share count, if dilutive, any exchange of limited partnership interests into shares of BGC Class A or BGC Class B common stock would not impact the fully diluted number of shares and units outstanding. Because these limited partnership interests generally receive quarterly allocations of net income, such exchange would have no significant impact on the cash flows or equity of the Company. Each quarter, net income (loss) is allocated between the limited partnership interests and the Company’s common stockholders. In quarterly periods in which the Company has a net loss, the loss allocation for FPUs, LPUs and Cantor units in BGC Holdings is allocated to Cantor and reflected as a component of “Net income (loss) attributable to noncontrolling interest in subsidiaries” in the Company’s Consolidated Statements of Operations. In subsequent quarters in which the Company has net income, the initial allocation of income to the limited partnership interests in BGC Holdings is to Cantor and is recorded as “Net income (loss) attributable to noncontrolling interests in subsidiaries,” to recover any losses taken in earlier quarters, with the remaining income allocated to the limited partnership interests. This income (loss) allocation process has no impact on the net income (loss) allocated to common stockholders.

Summary of Significant Accounti

Summary of Significant Accounting Policies	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Use of Estimates: The preparation of the Company’s consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of the assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities in these consolidated financial statements. Management believes that the estimates utilized in preparing these consolidated financial statements are reasonable. Estimates, by their nature, are based on judgment and available information. Actual results could differ materially from the estimates included in the Company’s consolidated financial statements. Certain reclassifications have been made to previously reported amounts to conform to the current period presentation. Revenue Recognition: BGC derives its revenues primarily through commissions from brokerage services, the spread between the buy and sell prices on matched principal transactions, fees from related parties, data, software and post-trade services, and other revenues. Commissions: The Company derives its commission revenues from securities, commodities and insurance-related transactions, whereby the Company connects buyers and sellers in the OTC and exchange markets and assists in the negotiation of the price and other material terms. These transactions result from the provision of service related to executing, settling and clearing transactions for customers. Trade execution and clearing services, when provided together, represent a single performance obligation as the services are not separately identifiable in the context of the contract. Commission revenues are recognized at a point in time on the trade-date, when the customer obtains control of the service and can direct the use of, and obtain substantially all of the remaining benefits from the asset. The Company records a receivable between the trade-date and settlement date when payment is received. Principal Transactions: Principal transaction revenues are primarily derived from matched principal transactions, whereby the Company simultaneously agrees to buy securities from one customer and sell them to another customer. A very limited number of trading businesses are allowed to enter into unmatched principal transactions to facilitate a customer’s execution needs for transactions initiated by such customers. Revenues earned from principal transactions represent the spread between the buy and sell price of the brokered security, commodity or derivative. Principal transaction revenues and related expenses are recognized on a trade-date basis. Positions held as part of a principal transaction are marked-to-market on a daily basis. Fees from Related Parties: Fees from related parties consist of charges for back-office services provided to Cantor and its affiliates, including occupancy of office space, utilization of fixed assets, accounting, operations, human resources and legal services, and information technology. The services are satisfied over time and measured using a time-elapsed measure of progress as the customer receives the benefits of the services evenly throughout the term of the contract. The transaction price is considered variable consideration as the level and type of services fluctuate from period to period and revenues are recognized only to the extent it is probable that a significant reversal in the amount of cumulative revenues recognized will not occur when the uncertainty is resolved. Fees from related parties are determined based on the cost incurred by the Company to perform or provide the service as evidenced by an allocation of employee expenses or a third-party invoice. Net cash settlements between affiliates are generally performed on a monthly basis. Data, Software and Post-trade: Data revenues primarily consist of subscription fees and fees from customized one-time sales provided to customers either directly or through third-party vendors. Regarding this revenue stream, the Company determined that software implementation, license usage, and related support services represent a single-performance obligation because the combination of these deliverables is necessary for the customer to derive benefit from the data. As such, once implementation is complete, monthly subscription fees are billed in advance and recognized on a straight-line basis over the life of the license period. The Company also provides software customization services contracted through work orders that each represent a separate performance obligation. Revenue is recognized over time using an output method as a measure of progress. As circumstances change over time, the Company updates its measure of progress to reflect any changes in the outcome of the performance obligation. Such updates are accounted for as a change in accounting estimate. As a practical expedient, when the work-order period is less than 12 months, the Company recognizes revenue upon acceptance from the customer after work is completed. The contract price is fixed and billed to the customer as combination of an upfront fee, progress fees, and a post-delivery fee. Other Revenues: Other revenues are earned from various sources, including underwriting and advisory fees. Other Income (Losses), Net: Gains (Losses) on Divestitures and Sale of Investments: Gains (losses) on divestitures and sale of investments is comprised of gains and losses recorded in connection with the divestiture of certain businesses or sale of investments (see Note 5—“Divestitures”). Gains (Losses) on Equity Method Investments: Gains (losses) on equity method investments represent the Company’s pro-rata share of the net gains and losses on investments over which the Company has significant influence but which it does not control. Other Income (Loss): Other income (loss) is primarily comprised of gains and losses associated with the movements related to the changes in fair value and/or hedges of Financial instruments owned, at fair value equity securities and investments carried under the measurement alternative (see Note 8—“Financial Instruments Owned, at Fair Value” and Note 14—“Investments”). Segments: The Company has one reportable segment (see Note 22—“Segment, Geographic and Product Information”). Cash and Cash Equivalents: The Company considers all highly liquid investments with maturities of 90 days or less at the date of acquisition that are not segregated under regulatory requirements, other than those used for trading purposes, to be cash equivalents. Cash and cash equivalents include money market funds, deposits with banks, certificates of deposit, commercial paper, and U.S. Treasury securities. Cash Segregated Under Regulatory Requirements: Cash segregated under regulatory requirements represents funds received in connection with customer activities that the Company is obligated to segregate or set aside to comply with regulations mandated by authorities such as the SEC and FINRA in the U.S. and the FCA in the U.K. that have been promulgated to protect customer assets. Financial Instruments Owned, at Fair Value: Financial instruments owned, at fair value primarily consist of unencumbered U.S. Treasury bills held for liquidity purposes as well as equity securities with readily determinable fair value, foreign government bonds, and corporate bonds. Debt securities presented within Financial instruments owned, at fair value are classified as trading and marked-to-market daily based on current listed market prices (or, when applicable, broker or dealer quotes), with the resulting gains and losses included in operating income in the current period. Unrealized and realized gains and losses from changes in fair value of these debt securities are included as part of “Principal transactions” in the Company’s Consolidated Statements of Operations. In accordance with the guidance on recognition and measurement of equity investments with readily determinable fair value, the Company carries these equity securities at fair value and recognizes any changes in fair value currently within “Other income (loss)” in the Company’s Consolidated Statements of Operations. See Note 8—“Financial Instruments Owned, at Fair Value” for additional information. Fair Value: U.S. GAAP defines fair value as the price received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and further expands disclosures about such fair value measurements. The guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows: Level 1 measurements – Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2 measurements – Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly. Level 3 measurements – Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. In determining fair value, the Company separates financial instruments owned and financial instruments sold, but not yet purchased into two categories: cash instruments and derivative contracts. Cash Instruments – Cash instruments are generally classified within Level 1 or Level 2. The types of instruments generally classified within Level 1 include most U.S. government securities, certain sovereign government obligations, and actively traded listed equities. The Company does not adjust the quoted price for such instruments. The types of instruments generally classified within Level 2 include agency securities, most investment-grade and high-yield corporate bonds, certain sovereign government obligations, money market securities, and less liquid listed equities, and state, municipal and provincial obligations. Derivative Contracts – Derivative contracts can be exchange-traded or OTC. Exchange-traded derivatives typically fall within Level 1 or Level 2 of the fair value hierarchy depending on whether they are deemed to be actively traded or not. The Company generally values exchange-traded derivatives using the closing price of the exchange-traded derivatives. OTC derivatives are valued using market transactions and other market evidence whenever possible, including market-based inputs to models, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency. For OTC derivatives that trade in liquid markets, such as generic forwards, swaps and options, model inputs can generally be verified and model selection does not involve significant management judgment. Such instruments are typically classified within Level 2 of the fair value hierarchy. See Note 12—“Fair Value of Financial Assets and Liabilities” for more information on the fair value of financial assets and liabilities. Receivables from and Payables to Broker-Dealers, Clearing Organizations, Customers and Related Broker-Dealers: Receivables from and payables to broker-dealers, clearing organizations, customers and related broker-dealers primarily represent principal transactions for which the stated settlement dates have not yet been reached and principal transactions which have not settled as of their stated settlement dates, cash held at clearing organizations and exchanges to facilitate settlement and clearance of matched principal transactions, and spreads on matched principal transactions that have not yet been remitted from/to clearing organizations and exchanges. Also included are amounts related to open derivative contracts, which are generally executed on behalf of the Company’s customers. A portion of the unsettled principal transactions and open derivative contracts that constitute receivables from and payables to broker-dealers, clearing organizations, customers and related broker-dealers are with related parties (see Note 13—“Related Party Transactions” for more information regarding these receivables and payables). Current Expected Credit Losses (CECL) In accordance with the U.S. GAAP guidance, Financial Instruments—Credit Losses , the Company presents its financial assets that are measured at amortized cost, net of an allowance for credit losses, which represents the amount expected to be collected over their estimated life. Expected credit losses for newly recognized financial assets carried at amortized cost, as well as changes to expected lifetime credit losses during the period, are recognized in earnings. The CECL methodology’s impact on expected credit losses, among other things, reflects the Company’s view of the current state of the economy, forecasted macroeconomic conditions and the Company’s portfolios. Refer to Note 25—“Current Expected Credit Losses (CECL)” for additional information. Accrued Commissions and Other Receivables, Net: The Company has accrued commissions receivable from securities and commodities transactions. Accrued commissions receivable are presented net of allowance for doubtful accounts of approximately $16.3 million and $9.9 million as of December 31, 2022 and 2021, respectively. The allowance is based on management’s estimate and reviewed periodically based on the facts and circumstances of each outstanding receivable. The Company’s CECL methodology for Accrued commissions receivable follows a PD/LGD framework with adjustments for the macroeconomic outlook, with the calculation performed at a counterparty level. The receivable balance for each counterparty is the outstanding receivable amount adjusted for any volume discounts. Accrued commissions receivable are not subject to an interest income accrual. The Company writes off a receivable in the period in which such balance is deemed uncollectible. The PD rate is sourced from Moody’s Annual Default Study for Corporates and it corresponds to the 1983-2022 average 1-year default rate by rating. The Moody’s quarterly updated data is used as well, if deemed appropriate. A significant number of the Company’s counterparties are publicly rated, and, therefore, the Moody’s PD rate is used as a proxy based on the counterparty’s external rating. In addition, the Company maintains internal obligor ratings that map to Moody’s long-term ratings. The LGD rate is derived from the Basel Committee’s June 2004 Second Basel Accord on international banking laws and regulations. The Company understands that the LGD assumption is a well-known industry benchmark for unsecured credits, which aligns with the unsecured nature of these receivables. Management considered that historically the Company has collected on substantially all its receivables, and, therefore, the LGD assumption is a reasonable benchmark in absence of internal data from which to develop an LGD measure. The macroeconomic adjustment is based on an average of the outlook scenarios for changes in the Real GDP growth rate for advanced economies over the next year. Historical and forecast data for this metric is obtained from the International Monetary Fund’s World Economic Outlook database. The Company believes that changes in expected credit losses for its counterparties are impacted by changes in broad economic activity and, therefore, determined that the Real GDP growth rate was a reasonable metric to evaluate for macroeconomic adjustments. Further, given that the Company’s receivables are related to counterparties with global operations, management sourced the data for this metric as applicable to advanced economies. The Company notes that, given the short-term nature of these receivables, a forecast beyond 1 year is neither required nor appropriate, and, therefore, the adjustment also covers the approximated life of these assets with no need for reversion. In the Company’s capacity as an insurance agent and broker, BGC collected premiums from insureds and, after deducting its commission, remitted the premiums to the respective insurers. BGC also collected claims or refunds from insurers on behalf of insureds. Uncollected premiums from insureds and uncollected claims or refunds from insurers were recorded as “Accrued commissions and other receivables, net”, and the corresponding unremitted insurance premiums and claims held in a fiduciary capacity were recorded as “Accounts payable, accrued and other liabilities” in the Company’s consolidated statements of financial condition. The Company sold its Insurance brokerage business on November 1, 2021 (see Note 5—"Divestitures" for additional information). Loans, Forgivable Loans, and Other Receivables from Employees and Partners, Net: The Company has entered into various agreements with certain employees and partners whereby these individuals receive loans which may be either wholly or in part repaid from the distributions that the individuals receive on some or all of their LPUs and from proceeds of the sale of the employees' shares of BGC Class A common stock, or may be forgiven over a period of time. The forgivable portion of these loans is not included in the Company’s estimate of expected credit losses when employees meet the conditions for forgiveness through their continued employment over the specified time period, and is recognized as compensation expense over the life of the loan. The amounts due from terminated employees that the Company does not expect to collect are included in the allowance for credit losses. From time to time, the Company may also enter into agreements with employees and partners to grant bonus and salary advances or other types of loans. These advances and loans are repayable in the timeframes outlined in the underlying agreements. The Company reviews loan balances each reporting period for collectability. If the Company determines that the collectability of a portion of the loan balances is not expected, the Company recognizes a reserve against the loan balances as compensation expense. Fixed Assets, Net: Fixed assets are carried at cost net of accumulated depreciation and amortization. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets. Internal and external direct costs of developing applications and obtaining software for internal use are capitalized and amortized over three years on a straight-line basis. Computer equipment is depreciated over three Asset Retirement Obligations . The guidance requires that the fair value of a liability for an asset retirement obligation be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. The associated asset retirement cost is capitalized as part of the carrying amount of the long-lived asset. The liability is discounted and accretion expense is recognized using the credit-adjusted risk-free interest rate in effect when the liability was initially recognized. Investments: The Company’s investments in which it has a significant influence but not a controlling financial interest and of which it is not the primary beneficiary are accounted for under the equity method. In accordance with the guidance on recognition and measurement of equity investments, the Company has elected to use a measurement alternative for its equity investments without a readily determinable fair value, pursuant to which these investments are initially recognized at cost and remeasured through earnings when there is an observable transaction involving the same or similar investment of the same issuer, or due to an impairment. The Company evaluates potential impairment of equity method investments when a change in circumstances occurs, by applying the U.S. GAAP guidance, under investments - Equity Method and Joint Ventures, and assessing whether the carrying amount can be recovered. See Note 12—“Fair Value of Financial Assets and Liabilities” and Note 14—“Investments” for additional information. The Company’s consolidated financial statements include the accounts of the Company and its wholly owned and majority-owned subsidiaries. The Company’s policy is to consolidate all entities of which it owns more than 50% unless it does not have control over the entity. In accordance with the U.S. GAAP guidance, Consolidation of Variable Interest Entities , the Company also consolidates any VIE of which it is the primary beneficiary. Long-Lived Assets: The Company periodically evaluates potential impairment of long-lived assets and amortizable intangibles, when a change in circumstances occurs, by applying the U.S. GAAP guidance, Impairment or Disposal of Long-Lived Assets , and assessing whether the unamortized carrying amount can be recovered over the remaining life through undiscounted future expected cash flows generated by the underlying assets. If the undiscounted future cash flows were less than the carrying value of the asset, an impairment charge would be recorded. The impairment charge would be measured as the excess of the carrying value of the asset over the present value of estimated expected future cash flows using a discount rate commensurate with the risks involved. Leases: The Company enters into leasing arrangements in the ordinary course of business as a lessee of office space, data centers and office equipment. BGC determines whether an arrangement is a lease at inception. ROU lease assets represent the Company’s right to use an underlying asset for the lease term, and lease liabilities represent BGC’s obligation to make lease payments arising from the lease. Other than for leases with an initial term of twelve months or less, ROU lease assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The ROU lease asset also includes any lease payments made and excludes lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise those options. Lease expense pertaining to leases is recognized on a straight-line basis over the lease term. Interest expense on finance leases is recognized using the effective interest method over the lease term. Refer to Note 24—“Leases” for additional information. Goodwill and Other Intangible Assets, Net: Goodwill is the excess of the purchase price over the fair value of identifiable net assets acquired in a business combination. As prescribed in the U.S. GAAP guidance, Intangibles—Goodwill and Other , goodwill and other indefinite-lived intangible assets are not amortized, but instead are periodically tested for impairment. The Company reviews goodwill and other indefinite-lived intangible assets for impairment on an annual basis during the fourth quarter of each fiscal year or whenever an event occurs or circumstances change that could reduce the fair value of a reporting unit below its carrying amount. When reviewing goodwill for impairment, BGC first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. Intangible assets with definite lives are amortized on a straight-line basis over their estimated useful lives. Definite-lived intangible assets arising from business combinations include customer relationships, internally developed software, and covenants not to compete. Also included in the definite-lived intangible assets are purchased patents. The costs of acquired patents are amortized over a period not to exceed the legal life or the remaining useful life of the patent, whichever is shorter, using the straight-line method. Income Taxes: The Company accounts for income taxes using the asset and liability method as prescribed in the U.S. GAAP guidance, Income Taxes . Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Certain of the Company’s entities are taxed as U.S. partnerships and are subject to the UBT in New York City. Therefore, the tax liability or benefit related to the partnership income or loss except for UBT rests with the partners (see Note 2—“Limited Partnership Interests in BGC Holdings and Newmark Holdings” for a discussion of partnership interests), rather than the partnership entity. As such, the partners’ tax liability or benefit is not reflected in the Company’s consolidated financial statements. The tax-related assets, liabilities, provisions or benefits included in the Company’s consolidated financial statements also reflect the results of the entities that are taxed as corporations, either in the U.S. or in foreign jurisdictions. The Company provides for uncertain tax positions based upon management’s assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities. The Company recognizes interest and penalties related to income tax matters in “Provision (benefit) for income taxes” in the Company’s consolidated statements of operations. The Company files income tax returns in the United States federal jurisdiction and various states, local and foreign jurisdictions. The Company is currently open to examination by tax authorities in United States federal, state and local jurisdictions and certain non-U.S. jurisdictions for tax years beginning 2017, 2009 and 2016, respectively. The Company has finalized its accounting policy with respect to taxes on Global Intangible Low-Taxed Income (GILTI) and has elected to treat taxes associated with the GILTI provision using the Period Cost Method and thus has not recorded deferred taxes for basis differences under this regime. Equity-Based Compensation: The Company accounts for equity-based compensation awards using the guidance in ASC 718, Compensation - Stock Compensation . Equity-based compensation expense recognized during the period, for equity-based awards with a stated vesting schedule, is based on the value of the portion of equity-based payment awards that is ultimately expected to vest. The grant-date fair value of equity-based awards with a stated vesting schedule is amortized to expense ratably over the awards’ vesting periods. As this equity-based compensation expense recognized in the Company’s consolidated statements of operations is based on awards ultimately expected to vest, it has been reviewed for estimated forfeitures. Further, forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. In addition, equity-based compensation for LPU awards with no stated vesting schedule, is recognized at fair value on the date the award is granted exchangeability or is redeemed in connection with the issuance of shares of common stock. Restricted Stock Units: RSUs held by certain employees of the Company are accounted for as equity awards, and in accordance with U.S. GAAP, the Company is required to record an expense for the portion of the RSUs that is ultimately expected to vest. The grant-date fair value of RSUs is amortized to expense ratably over the awards’ expected vesting periods. The non-cash equity-based amortization expense is reflected as a component of “Equity-based compensation and allocations of net income to limited partnership units and FPUs” in the Company’s consolidated statements of operations. Restricted Stock: Restricted stock provided to certain employees by the Company is accounted for as an equity award, and as per the U.S. GAAP guidance, the Company is required to record an expense for the portion of the restricted stock that is ultimately expected to vest. The Company has granted restricted stock that is fully vested and not subject to continued employment or service with the Company or any affiliate or subsidiary of the Company; however, transferability is subject to compliance with BGC Partners’ and its affiliates’ customary noncompete obligations. Such shares of restricted stock are generally salable by partners in five Limited Partnership Units: LPUs in BGC Holdings and Newmark Holdings generally are held by employees of both BGC and Newmark and receive quarterly allocations of net income, which are cash distributed on a quarterly basis and generally contingent upon services being provided by the unit holders. Following the Spin-Off, the quarterly allocations of net income on BGC Holdings and Newmark Holdings LPUs held by BGC employees are reflected as a component of compensation expense under “Equity-based compensation and allocations of net income to limited partnership units and FPUs,” and the quarterly allocations of net income on BGC Holdings LPUs held by Newmark employees are reflected as a component of “Net income (loss) attributable to noncontrolling interest in subsidiaries” in the Company’s consolidated statements of operations. Certain of these LPUs in BGC Holdings and Newmark Holdings, such as REUs, entitle the holders to receive post-termination payments equal to the notional amount in four equal yearly installments after the holder’s termination. These limited partnership units held by BGC employees are accounted for as post-termination liability awards under the U.S. GAAP guidance, which requires that the Company record an expense for such awards based on the change in value at each reporting period and include the expense in the Company’s consolidated statements of operations as part of “Equity-based compensation and allocations of net income to limited partnership units and FPUs.” The liability for these limited partnership units held by BGC employees with a post-termination payout amount is included in “Accrued compensation” on the Company’s consolidated statements of financial condition. Following the Spin-Off, certain limited partnership units in BGC Holdings are granted exchangeability or redeemed in connection with the grant of shares of BGC Class A common stock on a one-for-one basis (subject to adjustment), and certain limited partnership units in Newmark Holdings are granted exchangeability or redeemed in connection with the grant of shares of Newmark Class A common stock based on the exchange ratio at the time. At the time exchangeability or redemption is granted for BGC employees, the Company recognizes an expense based on the fair value of the award on that date, which is included in “Equity-based compensation and allocations of net income to limited partnership units and FPUs” in the Company’s consolidated statements of operations. Further, certain LPUs in BGC Holdings and Newmark Holdings have a stated vesting schedule and do not receive quarterly allocations of net income. The grant-date fair value of these LPUs is amortized to expense ratably over the awards’ expected vesting periods. The non-cash equity-based amortization expense is reflected as a component of “Equity-based compensation and allocations of net income to limited partnership units and FPUs” in the Company’s consolidated statements of operations. In addition, Preferred Units are granted in connection with the grant of certain LPUs, such as PSUs, which may be granted exchangeability or redeemed in connection with the grant of shares of common stock to cover the withholding taxes owed by the unit holder, rather than issuing the gross amount of shares to employees, subject to cashless withholding of shares to pay applicable withholding taxes. Each quarter, the net profits of BGC Holdings and Newmark Holdings are allocated to Preferred Units at a rate of either 0.6875% (which is 2.75% per calendar year) or such other amount as set forth in the award documentation (the “Preferred Distribution”). These allocations are deducted before the calculation and distribution of the quarterly partnership distribution for the remaining partnership interests and are generally contingent upon services being provided by the unit holder. The Preferred Units are not entitled to participate in partnership distributi

Earnings Per Share

Earnings Per Share	12 Months Ended

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share U.S. GAAP guidance establishes standards for computing and presenting EPS. Basic EPS excludes dilution and is computed by dividing net income (loss) available to common stockholders by the weighted-average number of shares of common stock outstanding and contingent shares for which all necessary conditions have been satisfied except for the passage of time. Net income (loss) is allocated to the Company’s outstanding common stock, FPUs, LPUs and Cantor units (see Note 2—“Limited Partnership Interests in BGC Holdings and Newmark Holdings”). Basic Earnings Per Share: The following is the calculation of the Company’s basic EPS (in thousands, except per share data): Year Ended December 31, 2022 2021 2020 Basic earnings (loss) per share: Net income (loss) available to common stockholders $ 48,712 $ 124,007 $ 45,062 Basic weighted-average shares of common stock outstanding 371,561 379,215 361,736 Basic earnings (loss) per share $ 0.13 $ 0.33 $ 0.12 Fully Diluted Earnings Per Share: Fully diluted EPS is calculated utilizing net income (loss) available to common stockholders plus net income allocations to the limited partnership interests as the numerator. The denominator comprises the Company’s weighted-average number of outstanding shares of BGC common stock, including contingent shares of BGC common stock, and, if dilutive, the weighted-average number of limited partnership interests, including contingent units of BGC Holdings, and other contracts to issue shares of BGC common stock, including RSUs. The limited partnership interests generally are potentially exchangeable into shares of BGC Class A common stock (see Note 2—“Limited Partnership Interests in BGC Holdings and Newmark Holdings”) and are entitled to their pro-rata share of earnings after the deduction for the Preferred Distribution; as a result, they are included in the fully diluted EPS computation to the extent that the effect would be dilutive. The following is the calculation of the Company’s fully diluted EPS (in thousands, except per share data): Year Ended December 31, 2022 2021 2020 Fully diluted earnings (loss) per share: Net income (loss) available to common stockholders $ 48,712 $ 124,007 $ 45,062 Allocations of net income (loss) to limited partnership interests, net of tax 14,767 49,988 19,725 Net income (loss) for fully diluted shares $ 63,479 $ 173,995 $ 64,787 Weighted-average shares: Common stock outstanding 371,561 379,215 361,736 Partnership units ¹ 124,738 155,356 183,130 RSUs (Treasury stock method) 1,913 4,074 737 Other 1,202 1,375 1,245 Fully diluted weighted-average shares of common stock outstanding 499,414 540,020 546,848 Fully diluted earnings (loss) per share $ 0.13 $ 0.32 $ 0.12 ____________________________________ 1 Partnership units collectively include FPUs, LPUs, and Cantor units (see Note 2—“Limited Partnership Interests in BGC Holdings and Newmark Holdings” for more information). For the years ended December 31, 2022, 2021 and 2020, approximately 0.5 million, 0.1 million and 0.7 million of potentially dilutive securities, respectively, were excluded from the computation of fully diluted EPS because their effect would have been anti-dilutive. Anti-dilutive securities for the year ended December 31, 2022 included 0.5 million RSUs. Anti-dilutive securities for the year ended December 31, 2021 included 0.1 million RSUs. Anti-dilutive securities for the year ended December 31, 2020 included 0.7 million RSUs. As of December 31, 2022, 2021 and 2020, approximately 50.2 million, 36.4 million and 27.7 million shares, respectively, of contingent shares of BGC Class A common stock, N units, RSUs, and LPUs were excluded from the fully diluted EPS computations because the conditions for issuance had not been met by the end of the respective periods.

Stock Transactions and Unit Redemptions	Stock Transactions and Unit Redemptions Class A Common Stock Changes in shares of BGC Class A common stock outstanding for the years ended December 31, 2022 and 2021 were as follows (in thousands): Year Ended December 31, 2022 2021 Shares outstanding at beginning of period 317,023 323,018 Share issuances: Redemptions/exchanges of limited partnership interests ¹ 30,998 58,025 Vesting of RSUs 3,284 2,167 Acquisitions 1,206 1,789 Other issuances of BGC Class A common stock 501 417 Treasury stock repurchases (27,087) (68,253) Forfeitures of restricted BGC Class A common stock (67) (140) Shares outstanding at end of period 325,858 317,023 ____________________________________ 1. Included in redemptions/exchanges of limited partnership interests for the year ended December 31, 2022 are 20.9 million shares of BGC Class A common stock granted in connection with the cancellation of 21.4 million LPUs. Included in redemption/exchanges of limited partnership interests for the year ended December 31, 2021, are 27.5 million shares of BGC Class A common stock granted in connection with the cancellation of 29.7 million LPUs. Because LPUs are included in the Company’s fully diluted share count, if dilutive, redemptions/exchanges in connection with the issuance of BGC Class A common stock would not impact the fully diluted number of shares outstanding. Class B Common Stock The Company did not issue any shares of BGC Class B common stock during the years ended December 31, 2022 and 2021. As of December 31, 2022 and 2021, there were 45.9 million shares of BGC Class B common stock outstanding. CEO Program On March 9, 2018, the Company filed the March 2018 Form S-3 and entered into the March 2018 Sales Agreement, pursuant to which the Company could offer and sell up to an aggregate of $300.0 million of shares of BGC Class A common stock under the CEO Program. CF&Co is a wholly-owned subsidiary of Cantor and an affiliate of the Company. Under the March 2018 Sales Agreement, the Company agreed to pay CF&Co 2% of the gross proceeds from the sale of shares. The Company did not sell any shares under the March 2018 Sales Agreement during the year ended December 31, 2021. The March 2018 Form S-3 and the March 2018 Sales Agreement expired in September 2021. As of the date of expiration, the Company had sold 17.6 million shares of BGC Class A common stock (or $210.8 million) under the March 2018 Sales Agreement. For additional information on the Company’s CEO Program sales agreements, see Note 13—“Related Party Transactions.” On March 8, 2021, the Company filed a new CEO Program shelf registration statement on Form S-3 with respect to the issuance and sale of up to an aggregate of $300.0 million of shares of BGC Class A common stock from time to time on a delayed or continuous basis (the "March 2021 Form S-3"). On July 8, 2022, the Company filed an amendment to the March 2021 Form S-3. On August 3, 2022, the March 2021 Form S-3 was declared effective by the SEC, and the Company entered into the August 2022 Sales Agreement on August 12, 2022. Unit Redemptions and Share Repurchase Program The Company’s Board and Audit Committee have authorized repurchases of BGC Class A common stock and redemptions of limited partnership interests or other equity interests in the Company’s subsidiaries. On August 3, 2021, the Company’s Board and Audit Committee increased the BGC Partners share repurchase and unit redemption authorization to $400.0 million, which may include purchases from Cantor, its partners or employees or other affiliated persons or entities. Again, on November 4, 2022, the Board and Audit Committee increased the BGC Partners share repurchase and unit redemption authorization to $400.0 million, which may include purchases from Cantor, its partners or employees or other affiliated persons or entities. As of December 31, 2022, the Company had $376.4 million remaining from its share repurchase and unit redemption authorization. From time to time, the Company may actively continue to repurchase shares and/or redeem units. The tables below represent the units redeemed and/or shares repurchased for cash and does not include units redeemed/cancelled in connection with the grant of shares of BGC Class A common stock nor the limited partnership interests exchanged for shares of BGC Class A common stock. The gross unit redemptions and share repurchases of BGC Class A common stock during the year ended December 31, 2022 were as follows (in thousands, except for weighted-average price data): Period Total Number Weighted- Approximate Redemptions 1 January 1, 2022—March 31, 2022 43 $ 4.01 April 1, 2022—June 30, 2022 1,010 3.81 July 1, 2022—September 30, 2022 214 3.91 October 1, 2022—December 31, 2022 99 3.88 Total Redemptions 1,366 $ 3.84 Repurchases 2 January 1, 2022—March 31, 2022 — $ — April 1, 2022—June 30, 2022 8,745 3.36 July 1, 2022—September 30, 2022 12,397 4.03 October 1, 2022—October 31, 2022 307 3.93 November 1, 2022—November 30, 2022 3,834 3.99 December 1, 2022—December 31, 2022 1,804 4.48 Total Repurchases 27,087 3.84 Total Redemptions and Repurchases 28,453 $ 3.84 $ 376,413 ____________________________________ 1. During the year ended December 31, 2022, the Company redeemed 1.3 million LPUs at an aggregate redemption price of $4.9 million for a weighted-average price of $3.87 per unit and 0.1 million FPUs at an aggregate redemption price of $0.4 million for a weighted-average price of $3.41 per unit.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives In the normal course of operations, the Company enters into derivative contracts to facilitate client transactions, hedge principal positions and facilitate hedging activities of affiliated companies. These derivative contracts primarily consist of FX swaps, FX/commodities options, futures and forwards. Derivative contracts can be exchange-traded or OTC. Exchange-traded derivatives typically fall within Level 1 or Level 2 of the fair value hierarchy depending on whether they are deemed to be actively traded or not. The Company generally values exchange-traded derivatives using their closing prices. OTC derivatives are valued using market transactions and other market evidence whenever possible, including market-based inputs to models, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency. For OTC derivatives that trade in liquid markets, such as forwards, swaps and options, model inputs can generally be verified and model selection does not involve significant management judgment. Such instruments are typically classified within Level 2 of the fair value hierarchy. The Company does not designate any derivative contracts as hedges for accounting purposes. U.S. GAAP guidance requires that an entity recognize all derivative contracts as either assets or liabilities in the Consolidated Statements of Financial Condition and measure those instruments at fair value. The fair value of all derivative contracts is recorded on a net-by-counterparty basis where a legal right to offset exists under an enforceable netting agreement. Derivative contracts are recorded as part of “Receivables from broker-dealers, clearing organizations, customers and related broker-dealers” and “Payables to broker-dealers, clearing organizations, customers and related broker-dealers” in the Company’s Consolidated Statements of Financial Condition. The fair value of derivative contracts, computed in accordance with the Company’s netting policy, is set forth below (in thousands): December 31, 2022 December 31, 2021 Derivative contract Assets Liabilities Notional Amounts 1 Assets Liabilities Notional Amounts 1 FX swaps $ 3,134 $ 5,796 $ 586,020 $ 2,487 $ 1,490 $ 571,280 Forwards 603 569 197,278 392 419 207,966 Interest rate swaps 25 — 2,114,412 — — — Futures — 1,268 4,253,088 — 940 3,914,813 Total $ 3,762 $ 7,633 $ 7,150,798 $ 2,879 $ 2,849 $ 4,694,059 ____________________________________ 1. Notional amounts represent the sum of gross long and short derivative contracts, an indication of the volume of the Company’s derivative activity, and do not represent anticipated losses. Certain of the Company’s FX swaps are with Cantor. See Note 13—“Related Party Transactions” for additional information related to these transactions.

Fair Value Disclosures [Abstract]
Fair Value of Financial Assets and Liabilities	Fair Value of Financial Assets and Liabilities Fair Value Measurements on a Recurring Basis U.S. GAAP guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows: Level 1 measurements—Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2 measurements—Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly. Level 3 measurements—Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. As required by U.S. GAAP guidance, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The following tables set forth by level within the fair value hierarchy financial assets and liabilities accounted for at fair value under U.S. GAAP guidance (in thousands): Assets at Fair Value at December 31, 2022 Level 1 Level 2 Level 3 Netting and Collateral Total Financial instruments owned, at fair value - Domestic Government debt $ 31,175 $ — $ — $ — $ 31,175 Financial instruments owned, at fair value - Foreign government debt — 7,678 — — 7,678 Financial instruments owned, at fair value - Equities 466 — — — 466 FX swaps — 3,623 — (489) 3,134 Forwards — 746 — (143) 603 Interest rate swaps — 895 — (870) 25 Futures — 64,769 — (64,769) — Total $ 31,641 $ 77,711 $ — $ (66,271) $ 43,081 Liabilities at Fair Value at December 31, 2022 Level 1 Level 2 Level 3 Netting and Collateral Total FX swaps $ — $ 6,285 $ — $ (489) $ 5,796 Futures — 66,037 — (64,769) 1,268 Forwards — 712 — (143) 569 Interest rate swaps — 870 — (870) — Contingent consideration — — 24,279 — 24,279 Total $ — $ 73,904 $ 24,279 $ (66,271) $ 31,912 Assets at Fair Value at December 31, 2021 Level 1 Level 2 Level 3 Netting and Collateral Total Financial instruments owned, at fair value - Domestic Government debt $ 30,956 $ — $ — $ — $ 30,956 Financial instruments owned, at fair value - Foreign government debt — 9,646 — — 9,646 Financial instruments owned, at fair value - Equities 641 — — — 641 Financial instruments owned, at fair value - Corporate bonds — 1 — — 1 Forwards — 452 — (60) 392 FX swaps — 3,025 — (538) 2,487 Futures — 70,497 — (70,497) — Total $ 31,597 $ 83,621 $ — $ (71,095) $ 44,123 Liabilities at Fair Value at December 31, 2021 Level 1 Level 2 Level 3 Netting and Total Futures $ — $ 71,437 $ — $ (70,497) $ 940 FX swaps — 2,028 — (538) 1,490 Forwards — 479 — (60) 419 Contingent consideration — — 29,756 — 29,756 Total $ — $ 73,944 $ 29,756 $ (71,095) $ 32,605 Level 3 Financial Liabilities Changes in Level 3 liabilities measured at fair value on a recurring basis for the year ended December 31, 2022 were as follows (in thousands): Unrealized (gains) Losses for the period included in: Opening Balance as of January 1, 2022 Total realized and unrealized (gains) losses included in Net income (loss) 1 Unrealized (gains) losses included in Other comprehensive income (loss) 2 Purchases/ Sales/ Closing Balance at December 31, 2022 Net income (loss) on Level 3 Assets / Liabilities Outstanding at December 31, Other comprehensive income (loss) on Level 3 Assets / Liabilities Outstanding at December 31, Liabilities Accounts payable, accrued and other liabilities: Contingent consideration $ 29,756 $ 1,034 $ — $ — $ (6,511) $ 24,279 $ 1,034 $ — _______________________________________ 1.

The discount rate is based on the Company’s calculated weighted-average cost of capital. 2. The probability of meeting the earnout targets was based on the acquirees’ projected future financial performance, including revenues. Information About Uncertainty of Level 3 Fair Value Measurements The significant unobservable inputs used in the fair value of the Company’s contingent consideration are the discount rate and forecasted financial information. Significant increases (decreases) in the discount rate would have resulted in a significantly lower (higher) fair value measurement. Significant increases (decreases) in the forecasted financial information would have resulted in a significantly higher (lower) fair value measurement. As of December 31, 2022 and 2021, the present value of expected payments related to the Company’s contingent consideration was $24.3 million and $29.8 million, respectively. The undiscounted value of the payments, assuming that all contingencies are met, would be $34.7 million and $40.6 million as of December 31, 2022 and 2021, respectively. Fair Value Measurements on a Non-Recurring Basis Pursuant to the recognition and measurement guidance for equity investments, equity investments carried under the measurement alternative are remeasured at fair value on a non-recurring basis to reflect observable transactions which occurred during the period. The Company applied the measurement alternative to equity securities with the fair value of approximately $83.8 million and $82.0 million, which were included in “Other assets” in the Company’s Consolidated Statements of Financial Condition as of December 31, 2022 and 2021, respectively. These investments are classified within Level 2 in the fair value hierarchy, because their estimated fair value is based on valuation methods using the observable transaction price at the transaction date.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Service Agreements Throughout Europe and Asia, the Company provides Cantor with administrative services, tec hnology services and other support, for which it charges Cantor based on the cost of providing such services plus a mark-up, generally 7.5%. In the U.K., the Company provides these services to Cantor through Tower Bridge. The Company owns 52% of Tower Bridge and consolidates it, and Cantor owns 48%. Cantor’s interest in Tower Bridge is reflected as a component of “Noncontrolling interest in subsidiaries” in the Company’s Consolidated Statements of Financial Condition, and the portion of Tower Bridge’s income attributable to Cantor is included as part of “Net income (loss) attributable to noncontrolling interest in subsidiaries” in the Company’s Consolidated Statements of Operations. In the U.S., the Company provides Cantor with technology services, for which it charges Cantor based on the cost of providing such services. The administrative services agreement provides that direct costs incurred are charged back to the service recipient. Additionally, the service recipient generally indemnifies the service provider for liabilities that it incurs arising from the provision of services, other than liabilities arising from fraud or willful misconduct of the service provider. In accordance with the administrative service agreement, the Company has not recognized any liabilities related to services provided to affiliates. For the years ended December 31, 2022, 2021 and 2020, Cantor’s share of the net profit (loss) in Tower Bridge was $0.7 million, $2.5 million and $0.8 million, respectively. This net profit is included as part of “Net income (loss) attributable to noncontrolling interest in subsidiaries” in the Company’s Consolidated Statements of Operations. On September 21, 2018, the Company entered into agreements to provide a guarantee and related obligation to Tower Bridge in connection with an office lease for the Company’s headquarters in London. The Company is obligated to guarantee the obligations of Tower Bridge in the event of certain defaults under the applicable lease and ancillary arrangements. In July 2018, the Audit Committee also authorized management of the Company to enter into similar guarantees or provide other forms of credit support to Tower Bridge or other affiliates of the Company from time to time in the future in similar circumstances and on similar terms and conditions. For the years ended December 31, 2022, 2021 and 2020, the Company recognized related party revenues of $14.7 million, $14.9 million and $25.8 million, respectively, for the services provided to Cantor. These revenues are included as part of “Fees from related parties” in the Company’s Consolidated Statements of Operations. In the U.S., Cantor and its affiliates provide the Company with administrative services and other support for which Cantor charges the Company based on the cost of providing such services. In connection with the services Cantor provides, the Company and Cantor entered into an administrative services agreement whereby certain employees of Cantor are deemed leased employees of the Company. For the years ended December 31, 2022, 2021 and 2020, the Company was charged $84.9 million, $81.9 million and $62.6 million, respectively, for the services provided by Cantor and its affiliates, of which $59.2 million, $57.9 million and $39.4 million, respectively, were to cover compensation to leased employees for the years ended December 31, 2022, 2021 and 2020. The fees charged by Cantor for administrative and support services, other than those to cover the compensation costs of leased employees, are included as part of “Fees to related parties” in the Company’s Consolidated Statements of Operations. The fees charged by Cantor to cover the compensation costs of leased employees are included as part of “Compensation and employee benefits” in the Company’s Consolidated Statements of Operati ons. Purchase of Futures Exchange Group On July 30, 2021, the Company completed the purchase of the Futures Exchange Group for a purchase price of $4.9 million at closing, plus the cash held at closing by the Futures Exchange Group, and an earn-out, only payable out of the Company's portion of the profits of the Futures Exchange Group, capped at the amount Cantor contributed to the Futures Exchange Group prior to closing. The transaction has been accounted for as a transaction between entities under common control. As part of the purchase of the Futures Exchange Group, Cantor has agreed to indemnify the Company for certain expenses arising at the Futures Exchange Group up to a maximum of $1.0 million. As of December 31, 2022 and 2021, the Company had recorded assets of $1.0 million and $0.4 million, respectively, in the Company’s Consolidated Statements of Financial Condition for this indemnity. In addition, the Futures Exchange Group received capital contributions from Cantor of $5.3 million and $4.6 million, for the years ended December 31, 2021 and 2020, respectively. These capital contributions were made prior to BGC's acquisition of the Futures Exchange Group. There were no capital contributions received from Cantor by the Futures Exchange Group for the year ended December 31, 2022. Newmark Spin-Off The Separation and Distribution Agreement sets forth the agreements among BGC, Cantor, Newmark and their respective subsidiaries. As a result of the Separation, the limited partnership interests in Newmark Holdings were distributed to the holders of limited partnership interests in BGC Holdings, including Cantor, whereby each holder of BGC Holdings limited partnership interests at that time held a BGC Holdings limited partnership interest and a corresponding Newmark Holdings limited partnership interest, which is equal to a BGC Holdings limited partnership interest multiplied by the Contribution Ratio, divided by the Exchange Ratio. For additional information, see Note 2—“Limited Partnership Interests in BGC Holdings and Newmark Holdings.” Subsequent to the Spin-Off, there are remaining partners who hold limited partnership interests in BGC Holdings who are Newmark employees, and there are remaining partners who hold limited partnership interests in Newmark Holdings who are BGC employees. These limited partnership interests represent interests that were held prior to the Newmark IPO or were distributed in connection with the Separation. Following the Newmark IPO, employees of BGC and Newmark only receive limited partnership interests in BGC Holdings and Newmark Holdings, respectively. As a result of the Spin-Off, as the existing limited partnership interests in BGC Holdings held by Newmark employees and the existing limited partnership interests in Newmark Holdings held by BGC employees are exchanged/redeemed, the related capital can be contributed to and from Cantor, respectively. On November 30, 2018, BGC Partners caused its subsidiary, BGC Holdings, to distribute in the BGC Holdings Distribution pro rata all of the 1.5 million exchangeable interests of Newmark Holdings held by BGC Holdings immediately prior to the effective time of the BGC Holdings Distribution Date to its limited partners entitled to receive distributions on their BGC Holdings units who were holders of record of such units as of the Record Date (including Cantor and executive officers of BGC). The Newmark Holdings interests distributed to BGC Holdings partners in the BGC Holdings Distribution are exchangeable for shares of Newmark Class A common stock, and, in the case of the 0.4 million Newmark Holdings interests received by Cantor, also into shares of Newmark Class B common stock, at the current Exchange Ratio of 0.9303 shares of Newmark common stock per Newmark Holdings interest (subject to adjustment). Clearing Agreement with Cantor The Company receives certain clearing services from Cantor pursuant to its clearing agreement. These clearing services are provided in exchange for payment by the Company of third-party clearing costs and allocated costs. The costs associated with these payments are included as part of “Fees to related parties” in the Company’s Consolidated Statements of Operations. The costs for these services are included as part of the charges to BGC for services provided by Cantor and its affiliates as discussed in “Service Agreements” above. Other Agreements with Cantor The Company is authorized to enter into short-term arrangements with Cantor to cover any delivery failures in connection with U.S. Treasury securities transactions and to share equally in any net income resulting from such transactions, as well as any similar clearing and settlement issues. As of December 31, 2022, and December 31, 2021, the Company had not facilitated any Repurchase Agreements with Cantor. To more effectively manage the Company’s exposure to changes in FX rates, the Company and Cantor have agreed to jointly manage the exposure. As a result, the Company is authorized to divide the quarterly allocation of any profit or loss relating to FX currency hedging between the Company and Cantor. The amount allocated to each party is based on the total net exposure for the Company and Cantor. The ratio of gross exposures of the Company and Cantor is utilized to determine the shares of profit or loss allocated to each for the period. During the year ended December 31, 2022, the Company recognized its share of FX losses of $0.1 million. During the years ended December 31, 2021 and 2020, the Company recognized its share of FX gains of $0.5 million and $1.5 million, respectively. These gains and losses are included as part of “Other expenses” in the Company’s Consolidated Statements of Operations. Pursuant to the separation agreement relating to the Company’s acquisition of certain BGC businesses from Cantor in 2008, Cantor has a right, subject to certain conditions, to be the Company’s customer and to pay the lowest commissions paid by any other customer, whether by volume, dollar or other applicable measure. In addition, Cantor has an unlimited right to internally use market data from the Company without any cost. Any future related party transactions or arrangements between the Company and Cantor are subject to the prior approval by the Audit Committee. During the years ended December 31, 2022, 2021 and 2020, the Company recorded revenues from Cantor entities of $0.3 million, $0.1 million and $0.1 million, respectively, related to commissions paid to the Company by Cantor. These revenues are included as part of “Commissions” in the Company’s Consolidated Statements of Operations. The Company and Cantor are authorized to utilize each other’s brokers to provide brokerage services for securities not brokered by such entity, so long as, unless otherwise agreed, such brokerage services were provided in the ordinary course and on terms no less favorable to the receiving party than such services are provided to typical third-party customers. In August 2013, the Audit Committee authorized the Company to invest up to $350.0 million in an asset-backed commercial paper program for which certain Cantor entities serve as placement agent and referral agent. The program issues short-term notes to money market investors and is expected to be used by the Company from time to time as a liquidity management vehicle. The notes are backed by assets of highly rated banks. The Company is entitled to invest in the program so long as the program meets investment policy guidelines, including policies related to ratings. Cantor will earn a spread between the rate it receives from the short-term note issuer and the rate it pays to the Company on any investments in this program. This spread will be no greater than the spread earned by Cantor for placement of any other commercial paper note in the program. As of December 31, 2022 and December 31, 2021, the Company did not have any investments in the program. On June 5, 2015, the Company entered into the Exchange Agreement with Cantor providing Cantor, CFGM and other Cantor affiliates entitled to hold BGC Class B common stock the right to exchange from time to time, on a one-to-one basis, subject to adjustment, up to an aggregate of 34.6 million shares of BGC Class A common stock now owned or subsequently acquired by such Cantor entities for up to an aggregate of 34.6 million shares of BGC Class B common stock. Such shares of BGC Class B common stock, which currently can be acquired upon the exchange of Cantor units owned in BGC Holdings, are already included in the Company’s fully diluted share count and will not increase Cantor’s current maximum potential voting power in the common equity. The Exchange Agreement enabled the Cantor entities to acquire the same number of shares of BGC Class B common stock that they were already entitled to acquire without having to exchange its Cantor units in BGC Holdings. The Audit Committee and Board determined that it was in the best interests of the Company and its stockholders to approve the Exchange Agreement because it will help ensure that Cantor retains its units in BGC Holdings, which is the same partnership in which the Company’s partner employees participate, thus continuing to align the interests of Cantor with those of the partner employees. On November 23, 2018, in the Class B Issuance, BGC Partners issued 10.3 million shares of BGC Partners Class B common stock to Cantor and 0.7 million shares of BGC Partners Class B common stock to CFGM, in each case in exchange for shares of BGC Class A common stock owned by Cantor and CFGM, respectively, on a one-to-one basis pursuant to the Exchange Agreement. Pursuant to the Exchange Agreement, no additional consideration was paid to BGC Partners by Cantor or CFGM for the Class B Issuance. Following this exchange, Cantor and its affiliates have the right to exchange under the Exchange Agreement up to an aggregate of 23.6 million shares of BGC Class A common stock, now owned or subsequently acquired, or its Cantor units in BGC Holdings, into shares of BGC Class B common stock. As of December 31, 2022, Cantor and CFGM did not own any shares of BGC Class A common stock. The Company and Cantor have agreed that any shares of BGC Class B common stock issued in connection with the Exchange Agreement would be deducted from the aggregate number of shares of BGC Class B common stock that may be issued to the Cantor entities upon exchange of Cantor units in BGC Holdings. Accordingly, the Cantor entities will not be entitled to receive any more shares of BGC Class B common stock under this agreement than they were previously eligible to receive upon exchange of exchangeable limited partnership units. On March 19, 2018, the Company entered into the BGC Credit Agreement with Cantor. The BGC Credit Agreement provides for each party and certain of its subsidiaries to issue loans to the other party or any of its subsidiaries in the lender’s discretion in an aggregate principal amount up to $250.0 million outstanding at any time. The BGC Credit Agreement replaced the previous Credit Facility between BGC and an affiliate of Cantor. On August 6, 2018, the Company entered into an amendment to the BGC Credit Agreement, which increased the aggregate principal amount that could be loaned to the other party or any of its subsidiaries from $250.0 million to $400.0 million that can be outstanding at any time. The BGC Credit Agreement will mature on the earlier to occur of (a) March 19, 2023, after which the maturity date of the BGC Credit Agreement will continue to be extended for successive one-year periods unless prior written notice of non-extension is given by a lending party to a borrowing party at least six months in advance of such renewal date and (b) the termination of the BGC Credit Agreement by either party pursuant to its terms. The outstanding amounts under the BGC Credit Agreement will bear interest for any rate period at a per annum rate equal to the higher of BGC’s or Cantor’s short-term borrowing rate in effect at such time plus 1.00%. As of December 31, 2022 and 2021, there were no borrowings by BGC or Cantor outstanding under this Agreement. The Company did not record any interest expense related to the agreement for the years ended December 31, 2022 and 2021. The Company recorded interest expense related to the Agreement of $0.4 million for the year ended December 31, 2020. As part of the Company’s cash management process, the Company may enter into tri-party reverse repurchase agreements and other short-term investments, some of which may be with Cantor. As of December 31, 2022 and 2021, the Company ha d no reverse repurchase agreements outstanding. Receivables from and Payables to Related Broker-Dealers Amounts due to or from Cantor and Freedom, one of the Company’s equity method investments, are for transactional revenues under a technology and services agreement with Freedom, as well as for open derivative contracts. These are included as part of “Receivables from broker-dealers, clearing organizations, customers and related broker-dealers” or “Payables to broker-dealers, clearing organizations, customers and related broker-dealers” in the Company’s Consolidated Statements of Financial Condition.

The forgivable portion of these loans is recognized as compensation expense over the life of the loan. From time to time, the Company may also enter into agreements with employees and partners to grant bonus and salary advances or other types of loans. These advances and loans are repayable in the timeframes outlined in the underlying agreements. As of December 31, 2022 and 2021, the aggregate balance of employee loans, net, was $319.6 million and $287.0 million, respectively, and is included as “Loans, forgivable loans and other receivables from employees and partners, net” in the Company’s Consolidated Statements of Financial Condition.

See Note 17—“Notes Payable, Other and Short-term Borrowings” for more information regarding these obligations, including timing of payments and compliance with debt covenants. 2 Operating leases and finance leases are related to rental payments under various non-cancelable leases, principally for office space, data centers and office equipment, and are presented net of sublease payments to be received. As of December 31, 2022, there were no sublease payments to be received over the life of the agreements. 3 Interest on debt and collateralized borrowings also includes interest on the undrawn portion of the committed unsecured senior Revolving Credit Agreement which was calculated through the maturity date of the facility, which is March 10, 2025. As of December 31, 2022, the undrawn portion of the committed unsecured Revolving Credit Agreement was $375.0 million. 4 Short-term borrowings reflect approximately $1.9 million (BRL 20.0 million) of borrowing under the Company’s committed unsecured loan agreement. See Note 17—“Notes Payable, Other and Short-term Borrowings” for more information regarding this obligation. 5 The Company completed the calculation of the one-time transition tax on the deemed repatriation of foreign subsidiaries’ earnings pursuant to the Tax Act and previously recorded a net cumulative tax expense of $28.6 million, net of foreign tax credits, with an election to pay the taxes over eight years with 40% to be paid in equal installments over the first five years and the remaining 60% to be paid in installments of 15%, 20% and 25% in years six, seven and eight, respectively. The cumulative remaining balance as of December 31, 2022 is $20.2 million. 6 Other contractual obligations reflect commitments of $9.2 million to make charitable contributions, which are recorded as part of “Accounts payable, accrued and other liabilities” in the Company’s Consolidated Statements of Financial Condition. The amount payable each year reflects an estimate of future Charity Day obligations. In addition, as part of the Insurance Business Disposition, unvested equity and other awards previously granted by BGC to employees of its Insurance brokerage business were converted into the right to receive a cash payment from BGC; a significant portion of these awards was 50% vested and paid in cash at closing, with the remaining 50% vesting and to be paid in cash two years after closing. The remaining portion of these awards will have been 100% vested and paid in cash by two years after the closing. The payments after closing are only made if the applicable employee remains an employee of the Insurance brokerage business. The remaining portion of these awards is reflected as other contractual obligations, and is recorded as part of “Accounts payable, accrued and other liabilities” in the Company’s Consolidated Statements of Financial Condition. The Company is obligated for minimum rental payments under various non-cancelable operating leases, principally for office space, expiring at various dates through 2039. Certain of the leases contain escalation clauses that require payment of additional rent to the extent of increases in certain operating or other costs. As of December 31, 2022, minimum lease payments under these arrangements are as follows (in thousands): Net Lease Commitment Operating leases Finance leases 2023 $ 35,483 $ 1,802 2024 30,844 1,448 2025 26,301 1,448 2026 20,861 1,290 2027 18,656 627 2028 and thereafter 89,218 — Total $ 221,363 $ 6,615 The lease obligations shown above are presented net of payments to be received under a non-cancelable sublease. There are no sublease payments to be received over the life of the agreement. In addition to the above obligations under non-cancelable operating leases, the Company is also obligated to Cantor for rental payments under Cantor’s various non-cancelable leases with third parties, principally for office space and computer equipment, expiring at various dates through 2039. Certain of these leases have renewal terms at the Company’s option and/or escalation clauses (primarily based on the Consumer Price Index). Cantor allocates a portion of the rental payments to the Company based on square footage used. The Company also allocates a portion of the rental payments for which it is obligated under non-cancelable operating leases to Cantor and its affiliates. These allocations are based on square footage used (see Note 13—“Related Party Transactions” for more information). Rent expense for the years ended December 31, 2022, 2021 and 2020 was $40.2 million, $49.4 million and $51.1 million, respectively. Rent expense is included as part of “Occupancy and equipment” in the Company’s Consolidated Statements of Operations. In the event the Company anticipates incurring costs under any of its leases that exceed anticipated sublease revenues, it recognizes a loss and records a liability for the present value of the excess lease obligations over the estimated sublease rental income. There was no liability for future lease payments associated with vacant space as of December 31, 2022, 2021 and 2020. Contingent Payments Related to Acquisitions Since 2016, the Company has completed acquisitions whose purchase price included an aggregate of approximately 2.2 million shares of the Company’s Class A common stock (with an acquisition date fair value of approximately $9.2 million), 0.1 million LPUs (with an acquisition date fair value of approximately $0.2 million), 0.2 million RSUs (with an acquisition date fair value of approximately $1.2 million) and $37.5 million in cash that may be issued contingent on certain targets being met through 2023. The Company did not issue any contingent shares of BGC Class A common stock, LPUs, RSUs or cash for acquisitions during the years ended December 31, 2022 and 2021. During the year ended December 31, 2022, the contingent cash consideration increased by approximately $2.6 million to $14.5 million in cash that may be paid due to an increase in probability of payout. During the year ended December 31, 2021, the contingent cash consideration increased by approximately $3.7 million to $11.8 million in cash that may be paid due to an increase in probability of payout. As of December 31, 2022, the Company has issued 1.0 million shares of its Class A common stock, 0.2 million RSUs and paid $34.7 million in cash related to contingent payments for acquisitions completed since 2016. As of December 31, 2022, 1.3 million shares of the Company’s Class A common stock and 0.1 million RSUs remain to be issued, and $18.4 million in cash remains to be paid, net of forfeitures and other adjustments, if the targets are met. The Company’s contingent considerations are classified as Level 3 liabilities. See Note 12—“Fair Value of Financial Assets and Liabilities” for additional information. Contingencies In the ordinary course of business, various legal actions are brought and are pending against the Company and its subsidiaries in the U.S. and internationally. In some of these actions, substantial amounts are claimed. The Company is also involved, from time to time, in reviews, examinations, investigations and proceedings by governmental and self-regulatory agencies (both formal and informal) regarding the Company’s businesses, operations, reporting or other matters, which may result in regulatory, civil and criminal judgments, settlements, fines, penalties, injunctions, enhanced oversight, remediation, or other relief. The following generally does not include matters that the Company has pending against other parties which, if successful, would result in awards in favor of the Company or its subsidiaries. Employment, Competitor-Related and Other Litigation From time to time, the Company and its subsidiaries are involved in litigation, claims and arbitrations in the U.S. and internationally, relating to, inter alia, various employment matters, including with respect to termination of employment, hiring of employees currently or previously employed by competitors, terms and conditions of employment and other matters. In light of the competitive nature of the brokerage industry, litigation, claims and arbitration between competitors regarding employee hiring are not uncommon. The Company is also involved, from time to time, in other reviews, investigations and proceedings by governmental and self-regulatory agencies (both formal and informal) regarding the Company’s businesses. Any such actions may result in regulatory, civil or criminal judgments, settlements, fines, penalties, injunctions, enhanced oversight, remediation, or other relief. Legal reserves are established in accordance with U.S. GAAP guidance on Accounting for Contingencies when a material legal liability is both probable and reasonably estimable. Once established, reserves are adjusted when there is more information available or when an event occurs requiring a change. The outcome of such items cannot be determined with certainty. The Company is unable to estimate a possible loss or range of loss in connection with specific matters beyond its current accruals and any other amounts disclosed. Management believes that, based on currently available information, the final outcome of these current pending matters will not have a material adverse effect on the Company’s financial condition, results of operations, or cash flows. Letter of Credit Agreements The Company has irrevocable uncollateralized letters of credit with various banks, where the beneficiaries are clearing organizations through which it transacts, that are used in lieu of margin and deposits with those clearing organizations. As of December 31, 2022 and 2021, the Company was contingently liable for $1.6 million and $1.8 million, respectively, under these letters of credit. Risk and Uncertainties The Company generates revenues by providing financial intermediary and brokerage activities to institutional customers and by executing and, in some cases, clearing transactions for institutional counterparties. Revenues for these services are transaction-based. As a result, revenues could vary based on the transaction volume of global financial markets. Additionally, financing is sensitive to interest rate fluctuations, which could have an impact on the Company’s overall profitability. During the year ended December 31, 2022, the Company recorded a $11.4 million reserve for a potential loss associated with Russia's Invasion of Ukraine, which is included in "Other expenses" in the Company's Consolidated Statements of Operations, and which was recorded as part of the CECL reserve (see Note 25—“Current Expected Credit Losses (CECL)” for additional information). Insurance The Company is self-insured for health care claims, up to a stop-loss amount for eligible participating employees and qualified dependents in the U.S., subject to deductibles and limitations. The Company’s liability for claims incurred but not reported is determined based on an estimate of the ultimate aggregate liability for claims incurred. The estimate is calculated from actual claim rates and adjusted periodically as necessary. The Company has accrued $2.4 million and $0.4 million in health care claims as of December 31, 2022 and 2021, respectively. The Company does not expect health care claims to have a material impact on its financial condition, results of operations, or cash flows. Guarantees The Company provides guarantees to securities clearinghouses and exchanges which meet the definition of a guarantee under FASB interpretations. Under these standard securities clearinghouse and exchange membership agreements, members are required to guarantee, collectively, the performance of other members and, accordingly, if another member becomes unable to satisfy its obligations to the clearinghouse or exchange, all other members would be required to meet the shortfall.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s Consolidated Financial Statements include U.S. federal, state and local income taxes on the Company’s allocable share of the U.S. results of operations, as well as taxes payable to jurisdictions outside the U.S. In addition, certain of the Company’s entities are taxed as U.S. partnerships and are subject to the UBT in New York City. Therefore, the tax liability or benefit related to the partnership income or loss, except for UBT, rests with the partners (see Note 2—“Limited Partnership Interests in BGC Holdings and Newmark Holdings” for discussion of partnership interests), rather than the partnership entity. The provision for income taxes consisted of the following (in thousands): Year Ended December 31, 2022 2021 2020 Current: U.S. federal $ 12,949 $ (7,267) $ 239 U.S. state and local 6,147 4,940 6,828 Foreign 34,506 36,699 30,788 UBT (390) 588 (3) 53,212 34,960 37,852 Deferred: U.S. federal (17,083) (1,000) (11,050) U.S. state and local (1,596) (1,515) (5,848) Foreign 3,971 (12,098) 3,602 UBT 80 2,666 (3,253) (14,628) (11,947) (16,549) Provision for income taxes $ 38,584 $ 23,013 $ 21,303 The Company had pre-tax income (loss) of $97.5 million, $176.5 million and $72.2 million for the years ended December 31, 2022, 2021 and 2020, respectively. The Company had pre-tax income (loss) from domestic operations of $(286.8) million, $(642.4) million and $(212.0) million for the years ended December 31, 2022, 2021 and 2020, respectively. The Company had pre-tax income (loss) from foreign operations of $384.3 million, $818.9 million and $284.2 million for the years ended December 31, 2022, 2021 and 2020, respectively. Differences between the Company’s actual income tax expense and the amount calculated utilizing the U.S. federal statutory rates were as follows (in thousands): Year Ended December 31, 2022 2021 2020 Tax expense at federal statutory rate $ 20,584 $ 37,065 $ 15,166 Non-controlling interest 2,366 2,440 73 Incremental impact of foreign taxes compared to federal tax rate 8,122 5,009 (476) Other permanent differences 2,287 11,797 6,531 U.S. state and local taxes, net of U.S. federal benefit (876) 2,737 (321) New York City UBT (1,071) 2,929 (3,256) Other rate changes 153 (7,007) (12,783) Nontaxable gain on insurance disposition — (65,231) — Uncertain tax positions 3,496 (6,936) 1,475 U.S. tax on foreign earnings, net of tax credits 4,808 31,299 2,643 Prior year adjustments 4,189 (714) 1,076 Valuation allowance (4,670) 11,532 11,966 Other (804) (1,907) (791) Provision for income taxes $ 38,584 $ 23,013 $ 21,303 As of December 31, 2022, the Company’s intention is to permanently reinvest undistributed foreign pre-tax earnings in the Company’s foreign operations. While the one-time transition tax eliminated most of the income tax effects of repatriating the undistributed earnings, there could still be foreign and state and local tax effects on the distribution. Accordingly, no provision has been recorded on foreign and state and local taxes that would be applicable upon distribution of such earnings to the U.S. Further, determination of an estimate of deferred tax liability associated with the distribution of foreign earnings is not practicable. However, this policy will be further re-evaluated and assessed based on the Company’s overall business needs and requirements. The Company has finalized its accounting policy with respect to taxes on Global Intangible Low-Taxed Income (GILTI) and has elected to treat taxes associated with the GILTI provision using the Period Cost Method and thus have not recorded deferred taxes for basis differences under this regime as of December 31, 2022. Accordingly, the Company recorded a tax expense of $5.6 million, net of foreign tax credits, for the impact of the GILTI provision on its foreign subsidiaries. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recorded against deferred tax assets if it is deemed more likely than not that those assets will not be realized. Significant components of the Company’s deferred tax asset and liability consisted of the following (in thousands): Year Ended December 31, 2022 2021 Deferred tax asset Basis difference of investments $ 15,857 $ 15,906 Deferred compensation 70,361 70,635 Excess interest expense 39,645 31,319 Other deferred and accrued expenses 10,693 12,157 Net operating loss and credit carry-forwards 45,592 60,160 Total deferred tax asset 1 182,148 190,177 Valuation allowance (31,362) (48,623) Deferred tax asset, net of valuation allowance 150,786 141,554 Deferred tax liability Depreciation and amortization 19,675 24,331 Total deferred tax liability 1 19,675 24,331 Net deferred tax asset $ 131,111 $ 117,223 _______________________________________ 1 Before netting within tax jurisdictions. The Company has deferred tax assets associated with net operating losses in U.S. federal, state and local, and non-U.S. jurisdictions of $1.4 million, $4.2 million and $30.6 million, respectively. These losses will begin to expire in 2027, 2025 and 2023, respectively. The Company has deferred tax assets associated with tax credits in the U.S. of $9.4 million, which will begin to expire in 2030. The Company’s deferred tax asset and liability are included in the Company’s Consolidated Statements of Financial Condition as components of “Other assets” and “Accounts payable, accrued and other liabilities,” respectively. Pursuant to the U.S. GAAP guidance, Accounting for Uncertainty in Income Taxes , the Company provides for uncertain tax positions as a component of income tax expense based upon management’s assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities. A reconciliation of the beginning to the ending amounts of gross unrecognized tax benefits for the years ended December 31, 2022 and 2021 is as follows (in thousands): Balance, December 31, 2020 $ 12,187 Increases for prior year tax positions 884 Decreases for prior year tax positions (999) Increases for current year tax positions — Decreases related to settlements with taxing authorities — Decreases related to a lapse of applicable statute of limitations (7,678) Balance, December 31, 2021 $ 4,394 Increases for prior year tax positions 3,159 Decreases for prior year tax positions — Increases for current year tax positions — Decreases related to settlements with taxing authorities — Decreases related to a lapse of applicable statute of limitations — Balance, December 31, 2022 $ 7,553 As of December 31, 2022, the Company’s unrecognized tax benefits, excluding related interest and penalties, were $7.6 million, of which $7.6 million, if recognized, would affect the effective tax rate. The Company is currently open to examination by tax authorities in U.S. federal, state and local jurisdictions and certain non-U.S. jurisdictions for tax years beginning 2019, 2009 and 2016, respectively. The Company is currently under examination by tax authorities in the U.S. federal and certain state, local and foreign jurisdictions. The Company does not believe that the amounts of unrecognized tax benefits will materially change over the next 12 months.

Disaggregation of Revenue See Note 22—“Segment, Geographic and Product Information” for a further discussion on the allocation of revenues to geographic regions. Contract Balances The timing of the Company's revenue recognition may differ from the timing of payment by its customers. The Company records a receivable when revenue is recognized prior to payment and the Company has an unconditional right to payment. Alternatively, when payment precedes the provision of the related services, the Company records deferred revenue until the performance obligations are satisfied. The Company had receivables related to revenues from contracts with customers of $288.5 million and $296.4 million at December 31, 2022 and December 31, 2021, respectively. The Company had no impairments related to these receivables during the years ended December 31, 2022 and 2021. The Company’s deferred revenue primarily relates to customers paying in advance or billed in advance where the performance obligation has not yet been satisfied. Deferred revenue at December 31, 2022 and 2021 was $12.5 million and $9.2 million, respectively. During the years ended December 31, 2022 and 2021, the Company recognized revenue of $9.1 million and $9.0 million, respectively, that was recorded as deferred revenue at the beginning of the period.

Leases

Leases	12 Months Ended

Leases [Abstract]
Leases	LeasesThe Company, acting as a lessee, has operating leases and finance leases primarily relating to office space, data centers and office equipment. The leases have remaining lease terms of 0.1 years to 16.6 years, some of which include options to extend the leases in 1 to 10 year increments for up to 15 years. Renewal periods are included in the lease term only when renewal is reasonably certain, which is a high threshold and requires management to apply judgment to determine the appropriate lease term. Certain leases also include periods covered by an option to terminate the lease if the Company is reasonably certain not to exercise the termination option. The Company measures its lease payments by including fixed rental payments and, where relevant, variable rental payments tied to an index, such as the Consumer Price Index. Payments for leases in place before the date of adoption of ASC 842, Leases were determined based on previous leases guidance. The Company recognizes lease expense for its operating leases on a straight-line basis over the lease term and variable lease expense not included in the lease payment measurement is recognized as incurred. Pursuant to the accounting policy election, leases with an initial term of twelve months or less are not recognized on the balance sheet. The short-term lease expense over the period reasonably reflects the Company’s short-term lease commitments. ASC 842, Leases requires the Company to make certain assumptions and judgments in applying the guidance, including determining whether an arrangement includes a lease, determining the term of a lease when the contract has renewal or cancelation provisions, and determining the discount rate. The Company determines whether an arrangement is a lease or includes a lease at the contract inception by evaluating whether the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. If the Company has the right to obtain substantially all of the economic benefits from, and can direct the use of, the identified asset for a period of time, the Company accounts for the identified asset as a lease. The Company has elected the practical expedient to not separate lease and non-lease components for all leases other than real estate leases. The primary non-lease component that is combined with a lease component represents operating expenses, such as utilities, maintenance or management fees. As the rate implicit in the lease is not usually available, the Company used an incremental borrowing rate based on the information available at the adoption date of the new Leases standard in determining the present value of lease payments for existing leases. The Company has elected to use a portfolio approach for the incremental borrowing rate, applying corporate bond rates to the leases. The Company calculated the appropriate rates with reference to the lease term and lease currency. The Company uses information available at the lease commencement date to determine the discount rate for any new leases. The Company subleases certain real estate to its affiliates and to third parties. The value of these commitments is not material to the Company’s Consolidated Financial Statements. As of December 31, 2022, the Company did not have any leases that have not yet commenced but that create significant rights and obligations.

Basis of Presentation	Basis of Presentation The Company’s Consolidated Financial Statements and Notes to the Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the SEC and in conformity with U.S. GAAP. The Company’s Consolidated Financial Statements include the Company’s accounts and all subsidiaries in which the Company has a controlling interest. Intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications have been made to previously reported amounts to conform to the current presentation.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes . The ASU is part of the FASB’s simplification initiative, and it is expected to reduce cost and complexity related to accounting for income taxes by eliminating certain exceptions to the guidance in ASC 740, Income Taxes related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The guidance also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates, and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. BGC adopted the standard on the required effective date beginning January 1, 2021 on a prospective basis. The adoption of the standard did not have a material impact on the Company’s Consolidated Financial Statements. In January 2020, the FASB issued ASU No. 2020-01, Investments—Equity Securities (Topic 321) , Investments—Equity Method and Joint Ventures (Topic 323) , and Derivatives and Hedging (Topic 815)—Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (a consensus of the FASB Emerging Issues Task Force) . These amendments improve previous guidance by reducing diversity in practice and increasing comparability of the accounting for the interactions between these codification topics as they pertain to certain equity securities, investments under the equity method of accounting and forward contracts or purchased options to purchase securities that, upon settlement of the forward contract or exercise of the purchased option, would be accounted for under the equity method of accounting or the fair value option. BGC adopted the standard on the required effective date beginning January 1, 2021 on a prospective basis. The adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements. In October 2020, the FASB issued ASU No. 2020-10, Codification Improvements . The standard amends the Codification by moving existing disclosure requirements to (or adding appropriate references in) the relevant disclosure sections. The ASU also clarifies various provisions of the Codification by amending and adding new headings, cross-referencing, and refining or correcting terminology. BGC adopted the standard on the required effective date beginning January 1, 2021 and it was applied using a modified retrospective method of transition. The adoption of this guidance did not have an impact on the Company’s Consolidated Financial Statements. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . The guidance is designed to provide relief from the accounting analysis and impacts that may otherwise be required for modifications to agreements (e.g., loans, debt securities, derivatives, and borrowings) necessitated by reference rate reform as entities transition away from LIBOR and other interbank offered rates to alternative reference rates. This ASU also provides optional expedients to enable companies to continue to apply hedge accounting to certain hedging relationships impacted by reference rate reform. Application of the guidance is optional and only available in certain situations. The ASU is effective upon issuance and generally can be applied through December 31, 2022. In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848): Scope . The amendments in this standard are elective and principally apply to entities that have derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform (referred to as the “discounting transition”). The standard expands the scope of ASC 848, Reference Rate Reform and allows entities to elect optional expedients to derivative contracts impacted by the discounting transition. Similar to ASU No. 2020-04, provisions of this ASU are effective upon issuance and generally can be applied through December 31, 2022. During the first quarter of 2022, the Company elected to apply the practical expedients to modifications of qualifying contracts as continuation of the existing contract rather than as a new contract. The adoption of the new guidance did not have an impact on the Company's Consolidated Financial Statements. In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity . The standard is expected to reduce complexity and improve comparability of financial reporting associated with accounting for convertible instruments and contracts in an entity’s own equity. The ASU also enhances information transparency by making targeted improvements to the related disclosures guidance. Additionally, the amendments affect the diluted EPS calculation for instruments that may be settled in cash or shares and for convertible instruments. BGC adopted the standard on the required effective date beginning January 1, 2022, and it was applied using a modified retrospective method of transition. The adoption of this guidance did not have a material impact on the Company's Consolidated Financial Statements. In November 2021, the FASB issued ASU No. 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance . The standard requires business entities to make annual disclosures about transactions with a government they account for by analogizing to a grant or contribution accounting model. The guidance is aimed at increasing transparency about government assistance transactions that are not in the scope of other U.S. GAAP guidance. The ASU requires disclosure of the nature and significant terms and considerations of the transactions, the accounting policies used and the effects of those transactions on an entity’s financial statements. The new standard became effective for the Company’s
New Accounting Pronouncements	New Accounting Pronouncements In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers . The standard improves the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to the recognition of an acquired contract liability, as well as payment terms and their effect on subsequent revenue recognized by the acquirer. The ASU requires companies to apply guidance in ASC 606, Revenue from Contracts with Customers , to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination, and, thus, creates an exception to the general recognition and measurement principle in ASC 805, Business Combinations . The new standard became effective for the Company beginning January 1, 2023, and will be applied prospectively for business combinations occurring on or after the effective date. The adoption of this guidance is not expected to have a material impact on the Company’s Consolidated Financial Statements. In March 2022, the FASB issued ASU No. 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . The guidance is intended to improve the decision usefulness of information provided to investors about certain loan refinancings, restructurings, and write-offs. The standard eliminates the recognition and measurement guidance on TDRs for creditors that have adopted ASC 326, Financial Instruments — Credit Losses and requires them to make enhanced disclosures about loan modifications for borrowers experiencing financial difficulty. The new guidance also requires public business entities to present current-period gross write-offs (on a current year-to-date basis for interim-period disclosures) by year of origination in their vintage disclosures. The new standard became effective for the Company beginning January 1, 2023. The guidance for recognition and measurement of TDRs will be applied using a prospective transition method, and the amendments related to disclosures will be applied prospectively. The adoption of this guidance is not expected to have a material impact on the Company’s Consolidated Financial Statements. In September 2022, the FASB issued ASU No. 2022-04, Liabilities—Supplier Finance Programs (Subtopic 405-50): Debt Restructurings Disclosure of Supplier Finance Program Obligations . The guidance requires entities to disclose the key terms of supplier finance programs they use in connection with the purchase of goods and services along with information about their obligations under these programs, including a rollforward of those obligations. The new standard became effective for the Company beginning on January 1, 2023, except for the rollforward requirement, which is effective beginning January 1, 2024. The guidance requires retrospective application to all periods in which a balance sheet is presented, except for the rollforward requirement, which will be applied prospectively. The adoption of this guidance is not expected to have a material impact on the Company’s Consolidated Financial Statements. In December 2022, the FASB issued ASU No. 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848. ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting provided optional guidance to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The ASU was effective upon issuance and generally could be applied through December 31, 2022. Because the current relief in ASC 848, Reference Rate Reform may not cover a period of time during which a significant number of modifications may take place, the amendments in ASU No. 2022-06 defer the sunset date from December 31, 2022 to December 31, 2024, after which entities will no longer be permitted to apply the relief in ASC 848. The ASU is effective upon issuance. Management is currently evaluating the impact of the new standard on the Company’s consolidated financial statements.
Use of Estimates	Use of Estimates: The preparation of the Company’s consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of the assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities in these consolidated financial statements. Management believes that the estimates utilized in preparing these consolidated financial statements are reasonable. Estimates, by their nature, are based on judgment and available information. Actual results could differ materially from the estimates included in the Company’s consolidated financial statements. Certain reclassifications have been made to previously reported amounts to conform to the current period presentation.
Revenue Recognition	Revenue Recognition: BGC derives its revenues primarily through commissions from brokerage services, the spread between the buy and sell prices on matched principal transactions, fees from related parties, data, software and post-trade services, and other revenues.
Commissions	Commissions: The Company derives its commission revenues from securities, commodities and insurance-related transactions, whereby the Company connects buyers and sellers in the OTC and exchange markets and assists in the negotiation of the price and other material terms. These transactions result from the provision of service related to executing, settling and clearing transactions for customers. Trade execution and clearing services, when provided together, represent a single performance obligation as the services are not separately identifiable in the context of the contract. Commission revenues are recognized at a point in time on the trade-date, when the customer obtains control of the service and can direct the use of, and obtain
Principal Transactions	Principal Transactions: Principal transaction revenues are primarily derived from matched principal transactions, whereby the Company simultaneously agrees to buy securities from one customer and sell them to another customer. A very limited number of trading businesses are allowed to enter into unmatched principal transactions to facilitate a customer’s execution needs for transactions initiated by such customers. Revenues earned from principal transactions represent the spread between the buy and sell price of the brokered security, commodity or derivative. Principal transaction revenues and related expenses are recognized on a trade-date basis. Positions held as part of a principal transaction are marked-to-market on a daily basis.
Fees from Related Parties	Fees from Related Parties: Fees from related parties consist of charges for back-office services provided to Cantor and its affiliates, including occupancy of office space, utilization of fixed assets, accounting, operations, human resources and legal services, and information technology. The services are satisfied over time and measured using a time-elapsed measure of progress as the customer receives the benefits of the services evenly throughout the term of the contract. The transaction price is considered variable consideration as the level and type of services fluctuate from period to period and revenues are recognized only to the extent it is probable that a significant reversal in the amount of cumulative revenues recognized will not occur when the uncertainty is resolved. Fees from related parties are determined based on the cost incurred by the Company to perform or provide the service as evidenced by an allocation of employee expenses or a third-party invoice. Net cash settlements between affiliates are generally performed on a monthly basis.
Data, Software and Post-trade	Data, Software and Post-trade: Data revenues primarily consist of subscription fees and fees from customized one-time sales provided to customers either directly or through third-party vendors. Regarding this revenue stream, the Company determined that software implementation, license usage, and related support services represent a single-performance obligation because the combination of these deliverables is necessary for the customer to derive benefit from the data. As such, once implementation is complete, monthly subscription fees are billed in advance and recognized on a straight-line basis over the life of the license period. The Company also provides software customization services contracted through work orders that each represent a separate performance obligation. Revenue is recognized over time using an output method as a measure of progress. As circumstances change over time, the Company updates its measure of progress to reflect any changes in the outcome of the performance obligation. Such updates are accounted for as a change in accounting estimate. As a practical expedient, when the work-order period is less than 12 months, the Company recognizes revenue upon acceptance from the customer after work is completed. The contract price is fixed and billed to the customer as combination of an upfront fee, progress fees, and a post-delivery fee.
Other Revenues	Other Revenues: Other revenues are earned from various sources, including underwriting and advisory fees.
Other Income (Losses), Net	Other Income (Losses), Net: Gains (Losses) on Divestitures and Sale of Investments: Gains (losses) on divestitures and sale of investments is comprised of gains and losses recorded in connection with the divestiture of certain businesses or sale of investments (see Note 5—“Divestitures”). Gains (Losses) on Equity Method Investments: Gains (losses) on equity method investments represent the Company’s pro-rata share of the net gains and losses on investments over which the Company has significant influence but which it does not control.
Segments	Segments:The Company has one reportable segment (see Note 22—“Segment, Geographic and Product Information”).
Cash and Cash Equivalents	Cash and Cash Equivalents: The Company considers all highly liquid investments with maturities of 90 days or less at the date of acquisition that are not segregated under regulatory requirements, other than those used for trading purposes, to be cash equivalents. Cash and cash equivalents include money market funds, deposits with banks, certificates of deposit, commercial paper, and U.S. Treasury securities.
Cash Segregated Under Regulatory Requirements	Cash Segregated Under Regulatory Requirements: Cash segregated under regulatory requirements represents funds received in connection with customer activities that the Company is obligated to segregate or set aside to comply with regulations mandated by authorities such as the SEC and FINRA in the U.S. and the FCA in the U.K. that have been promulgated to protect customer assets.
Financial Instruments Owned, at Fair Value	Financial Instruments Owned, at Fair Value:Financial instruments owned, at fair value primarily consist of unencumbered U.S. Treasury bills held for liquidity purposes as well as equity securities with readily determinable fair value, foreign government bonds, and corporate bonds. Debt securities presented within Financial instruments owned, at fair value are classified as trading and marked-to-market daily based on current listed market prices (or, when applicable, broker or dealer quotes), with the resulting gains and losses included in operating income in the current period. Unrealized and realized gains and losses from changes in fair value of these debt securities are included as part of “Principal transactions” in the Company’s Consolidated Statements of Operations. In accordance with the guidance on recognition and measurement of equity investments with readily determinable fair value, the Company carries these equity securities at fair value and recognizes any changes in fair value currently within “Other income (loss)” in the Company’s Consolidated Statements of Operations.
Fair Value	Fair Value: U.S. GAAP defines fair value as the price received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and further expands disclosures about such fair value measurements. The guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows: Level 1 measurements – Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2 measurements – Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly. Level 3 measurements – Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. In determining fair value, the Company separates financial instruments owned and financial instruments sold, but not yet purchased into two categories: cash instruments and derivative contracts. Cash Instruments – Cash instruments are generally classified within Level 1 or Level 2. The types of instruments generally classified within Level 1 include most U.S. government securities, certain sovereign government obligations, and actively traded listed equities. The Company does not adjust the quoted price for such instruments. The types of instruments generally classified within Level 2 include agency securities, most investment-grade and high-yield corporate bonds, certain sovereign government obligations, money market securities, and less liquid listed equities, and state, municipal and provincial obligations. Derivative Contracts – Derivative contracts can be exchange-traded or OTC. Exchange-traded derivatives typically fall within Level 1 or Level 2 of the fair value hierarchy depending on whether they are deemed to be actively traded or not. The Company generally values exchange-traded derivatives using the closing price of the exchange-traded derivatives. OTC derivatives are valued using market transactions and other market evidence whenever possible, including market-based inputs to models, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency. For OTC derivatives that trade in liquid markets, such as generic forwards, swaps and options, model inputs can generally be verified and model selection does not involve significant management judgment. Such instruments are typically classified within Level 2 of the fair value hierarchy.
Receivables from and Payables to Broker-Dealers, Clearing Organizations, Customers and Related Broker-Dealers	Receivables from and Payables to Broker-Dealers, Clearing Organizations, Customers and Related Broker-Dealers: Receivables from and payables to broker-dealers, clearing organizations, customers and related broker-dealers primarily represent principal transactions for which the stated settlement dates have not yet been reached and principal transactions which have not settled as of their stated settlement dates, cash held at clearing organizations and exchanges to facilitate settlement and clearance of matched principal transactions, and spreads on matched principal transactions that have not yet been remitted from/to clearing organizations and exchanges. Also included are amounts related to open derivative contracts, which are generally executed on behalf of the Company’s customers. A portion of the unsettled principal transactions and open derivative contracts that constitute receivables from and payables to broker-dealers, clearing organizations, customers and related broker-dealers are with related parties (see Note 13—“Related Party Transactions” for more information regarding these receivables and payables).
Current Expected Credit Losses (CECL)	Current Expected Credit Losses (CECL) In accordance with the U.S. GAAP guidance, Financial Instruments—Credit Losses
Accrued Commissions and Other Receivables, Net	Accrued Commissions and Other Receivables, Net: The Company has accrued commissions receivable from securities and commodities transactions. Accrued commissions receivable are presented net of allowance for doubtful accounts of approximately $16.3 million and $9.9 million as of December 31, 2022 and 2021, respectively. The allowance is based on management’s estimate and reviewed periodically based on the facts and circumstances of each outstanding receivable. The Company’s CECL methodology for Accrued commissions receivable follows a PD/LGD framework with adjustments for the macroeconomic outlook, with the calculation performed at a counterparty level. The receivable balance for each counterparty is the outstanding receivable amount adjusted for any volume discounts. Accrued commissions receivable are not subject to an interest income accrual. The Company writes off a receivable in the period in which such balance is deemed uncollectible. The PD rate is sourced from Moody’s Annual Default Study for Corporates and it corresponds to the 1983-2022 average 1-year default rate by rating. The Moody’s quarterly updated data is used as well, if deemed appropriate. A significant number of the Company’s counterparties are publicly rated, and, therefore, the Moody’s PD rate is used as a proxy based on the counterparty’s external rating. In addition, the Company maintains internal obligor ratings that map to Moody’s long-term ratings. The LGD rate is derived from the Basel Committee’s June 2004 Second Basel Accord on international banking laws and regulations. The Company understands that the LGD assumption is a well-known industry benchmark for unsecured credits, which aligns with the unsecured nature of these receivables. Management considered that historically the Company has collected on substantially all its receivables, and, therefore, the LGD assumption is a reasonable benchmark in absence of internal data from which to develop an LGD measure. The macroeconomic adjustment is based on an average of the outlook scenarios for changes in the Real GDP growth rate for advanced economies over the next year. Historical and forecast data for this metric is obtained from the International Monetary Fund’s World Economic Outlook database. The Company believes that changes in expected credit losses for its counterparties are impacted by changes in broad economic activity and, therefore, determined that the Real GDP growth rate was a reasonable metric to evaluate for macroeconomic adjustments. Further, given that the Company’s receivables are related to counterparties with global operations, management sourced the data for this metric as applicable to advanced economies. The Company notes that, given the short-term nature of these receivables, a forecast beyond 1 year is neither required nor appropriate, and, therefore, the adjustment also covers the approximated life of these assets with no need for reversion. In the Company’s capacity as an insurance agent and broker, BGC collected premiums from insureds and, after deducting its commission, remitted the premiums to the respective insurers. BGC also collected claims or refunds from insurers on behalf of insureds. Uncollected premiums from insureds and uncollected claims or refunds from insurers were recorded as “Accrued commissions and other receivables, net”, and the corresponding unremitted insurance premiums and claims held in a fiduciary capacity were recorded as “Accounts payable, accrued and other liabilities” in the Company’s consolidated statements of financial condition. The Company sold its Insurance brokerage business on November 1, 2021 (see Note 5—"Divestitures" for additional information).
Loans, Forgivable Loans, and Other Receivables from Employees and Partners, Net	Loans, Forgivable Loans, and Other Receivables from Employees and Partners, Net: The Company has entered into various agreements with certain employees and partners whereby these individuals receive loans which may be either wholly or in part repaid from the distributions that the individuals receive on some or all of their LPUs and from proceeds of the sale of the employees' shares of BGC Class A common stock, or may be forgiven over a period of time. The forgivable portion of these loans is not included in the Company’s estimate of expected credit losses when employees meet the conditions for forgiveness through their continued employment over the specified time period, and is recognized as compensation expense over the life of the loan. The amounts due from terminated employees that the Company does not expect to collect are included in the allowance for credit losses. From time to time, the Company may also enter into agreements with employees and partners to grant bonus and salary advances or other types of loans. These advances and loans are repayable in the timeframes outlined in the underlying agreements. The Company reviews loan balances each reporting period for collectability. If the Company determines that the collectability of a portion of the loan balances is not expected, the Company recognizes a reserve against the loan balances as compensation expense.
Fixed Assets, Net	Fixed Assets, Net: Fixed assets are carried at cost net of accumulated depreciation and amortization. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets. Internal and external direct costs of developing applications and obtaining software for internal use are capitalized and amortized over three years on a straight-line basis. Computer equipment is depreciated over three Asset Retirement Obligations . The guidance requires that the fair value of a liability for an asset retirement obligation be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. The associated asset retirement cost is capitalized as part of the carrying amount of the long-lived asset. The liability is discounted and accretion expense is recognized using the credit-adjusted risk-free interest rate in effect when the liability was initially recognized.
Investments	Investments: The Company’s investments in which it has a significant influence but not a controlling financial interest and of which it is not the primary beneficiary are accounted for under the equity method. In accordance with the guidance on recognition and measurement of equity investments, the Company has elected to use a measurement alternative for its equity investments without a readily determinable fair value, pursuant to which these investments are initially recognized at cost and remeasured through earnings when there is an observable transaction involving the same or similar investment of the same issuer, or due to an impairment. The Company evaluates potential impairment of equity method investments when a change in circumstances occurs, by applying the U.S. GAAP guidance, under investments - Equity Method and Joint Ventures, and assessing whether the carrying amount can be recovered. See Note 12—“Fair Value of Financial Assets and Liabilities” and Note 14—“Investments” for additional information. The Company’s consolidated financial statements include the accounts of the Company and its wholly owned and majority-owned subsidiaries. The Company’s policy is to consolidate all entities of which it owns more than 50% unless it does not have control over the entity. In accordance with the U.S. GAAP guidance, Consolidation of Variable Interest Entities , the Company also consolidates any VIE of which it is the primary beneficiary.
Long-Lived Assets	Long-Lived Assets: The Company periodically evaluates potential impairment of long-lived assets and amortizable intangibles, when a change in circumstances occurs, by applying the U.S. GAAP guidance, Impairment or Disposal of Long-Lived Assets , and assessing whether the unamortized carrying amount can be recovered over the remaining life through undiscounted future expected cash flows generated by the underlying assets. If the undiscounted future cash flows were less than the carrying value of the asset, an impairment charge would be recorded. The impairment charge would be measured as the excess of the carrying value of the asset over the present value of estimated expected future cash flows using a discount rate commensurate with the risks involved.
Leases	Leases: The Company enters into leasing arrangements in the ordinary course of business as a lessee of office space, data centers and office equipment.
Goodwill and Other Intangible Assets, Net	Goodwill and Other Intangible Assets, Net: Goodwill is the excess of the purchase price over the fair value of identifiable net assets acquired in a business combination. As prescribed in the U.S. GAAP guidance, Intangibles—Goodwill and Other , goodwill and other indefinite-lived intangible assets are not amortized, but instead are periodically tested for impairment. The Company reviews goodwill and other indefinite-lived intangible assets for impairment on an annual basis during the fourth quarter of each fiscal year or whenever an event occurs or circumstances change that could reduce the fair value of a reporting unit below its carrying amount. When reviewing goodwill for impairment, BGC first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. Intangible assets with definite lives are amortized on a straight-line basis over their estimated useful lives. Definite-lived intangible assets arising from business combinations include customer relationships, internally developed software, and covenants not to compete. Also included in the definite-lived intangible assets are purchased patents. The costs of acquired patents are amortized over a period not to exceed the legal life or the remaining useful life of the patent, whichever is shorter, using the straight-line method.
Income Taxes	Income Taxes: The Company accounts for income taxes using the asset and liability method as prescribed in the U.S. GAAP guidance, Income Taxes . Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Certain of the Company’s entities are taxed as U.S. partnerships and are subject to the UBT in New York City. Therefore, the tax liability or benefit related to the partnership income or loss except for UBT rests with the partners (see Note 2—“Limited Partnership Interests in BGC Holdings and Newmark Holdings” for a discussion of partnership interests), rather than the partnership entity. As such, the partners’ tax liability or benefit is not reflected in the Company’s consolidated financial statements. The tax-related assets, liabilities, provisions or benefits included in the Company’s consolidated financial statements also reflect the results of the entities that are taxed as corporations, either in the U.S. or in foreign jurisdictions. The Company provides for uncertain tax positions based upon management’s assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities. The Company recognizes interest and penalties related to income tax matters in “Provision (benefit) for income taxes” in the Company’s consolidated statements of operations. The Company files income tax returns in the United States federal jurisdiction and various states, local and foreign jurisdictions. The Company is currently open to examination by tax authorities in United States federal, state and local jurisdictions and certain non-U.S. jurisdictions for tax years beginning 2017, 2009 and 2016, respectively. The Company has finalized its accounting policy with respect to taxes on Global Intangible Low-Taxed Income (GILTI) and has elected to treat taxes associated with the GILTI provision using the Period Cost Method and thus has not recorded deferred taxes for basis differences under this regime.
Equity-Based Compensation	Equity-Based Compensation: The Company accounts for equity-based compensation awards using the guidance in ASC 718, Compensation - Stock Compensation . Equity-based compensation expense recognized during the period, for equity-based awards with a stated vesting schedule, is based on the value of the portion of equity-based payment awards that is ultimately expected to vest. The grant-date fair value of equity-based awards with a stated vesting schedule is amortized to expense ratably over the awards’ vesting periods. As this equity-based compensation expense recognized in the Company’s consolidated statements of operations is based on awards ultimately expected to vest, it has been reviewed for estimated forfeitures. Further, forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. In addition, equity-based compensation for LPU awards with no stated vesting schedule, is recognized at fair value on the date the award is granted exchangeability or is redeemed in connection with the issuance of shares of common stock.
Restricted Stock Units	Restricted Stock Units: RSUs held by certain employees of the Company are accounted for as equity awards, and in accordance with U.S. GAAP, the Company is required to record an expense for the portion of the RSUs that is ultimately expected to vest. The grant-date fair value of RSUs is amortized to expense ratably over the awards’ expected vesting periods. The non-cash equity-based amortization expense is reflected as a component of “Equity-based compensation and allocations of net income to limited partnership units and FPUs” in the Company’s consolidated statements of operations.
Restricted Stock	Restricted Stock: Restricted stock provided to certain employees by the Company is accounted for as an equity award, and as per the U.S. GAAP guidance, the Company is required to record an expense for the portion of the restricted stock that is ultimately expected to vest. The Company has granted restricted stock that is fully vested and not subject to continued employment or service with the Company or any affiliate or subsidiary of the Company; however, transferability is subject to compliance with BGC Partners’ and its affiliates’ customary noncompete obligations. Such shares of restricted stock are generally salable by partners in five
Limited Partnership Units	Limited Partnership Units: LPUs in BGC Holdings and Newmark Holdings generally are held by employees of both BGC and Newmark and receive quarterly allocations of net income, which are cash distributed on a quarterly basis and generally contingent upon services being provided by the unit holders. Following the Spin-Off, the quarterly allocations of net income on BGC Holdings and Newmark Holdings LPUs held by BGC employees are reflected as a component of compensation expense under “Equity-based compensation and allocations of net income to limited partnership units and FPUs,” and the quarterly allocations of net income on BGC Holdings LPUs held by Newmark employees are reflected as a component of “Net income (loss) attributable to noncontrolling interest in subsidiaries” in the Company’s consolidated statements of operations. Certain of these LPUs in BGC Holdings and Newmark Holdings, such as REUs, entitle the holders to receive post-termination payments equal to the notional amount in four equal yearly installments after the holder’s termination. These limited partnership units held by BGC employees are accounted for as post-termination liability awards under the U.S. GAAP guidance, which requires that the Company record an expense for such awards based on the change in value at each reporting period and include the expense in the Company’s consolidated statements of operations as part of “Equity-based compensation and allocations of net income to limited partnership units and FPUs.” The liability for these limited partnership units held by BGC employees with a post-termination payout amount is included in “Accrued compensation” on the Company’s consolidated statements of financial condition. Following the Spin-Off, certain limited partnership units in BGC Holdings are granted exchangeability or redeemed in connection with the grant of shares of BGC Class A common stock on a one-for-one basis (subject to adjustment), and certain limited partnership units in Newmark Holdings are granted exchangeability or redeemed in connection with the grant of shares of Newmark Class A common stock based on the exchange ratio at the time. At the time exchangeability or redemption is granted for BGC employees, the Company recognizes an expense based on the fair value of the award on that date, which is included in “Equity-based compensation and allocations of net income to limited partnership units and FPUs” in the Company’s consolidated statements of operations. Further, certain LPUs in BGC Holdings and Newmark Holdings have a stated vesting schedule and do not receive quarterly allocations of net income. The grant-date fair value of these LPUs is amortized to expense ratably over the awards’ expected vesting periods. The non-cash equity-based amortization expense is reflected as a component of “Equity-based compensation and allocations of net income to limited partnership units and FPUs” in the Company’s consolidated statements of operations. In addition, Preferred Units are granted in connection with the grant of certain LPUs, such as PSUs, which may be granted exchangeability or redeemed in connection with the grant of shares of common stock to cover the withholding taxes owed by the unit holder, rather than issuing the gross amount of shares to employees, subject to cashless withholding of shares to pay applicable withholding taxes. Each quarter, the net profits of BGC Holdings and Newmark Holdings are allocated to Preferred Units at a rate of either 0.6875% (which is 2.75% per calendar year) or such other amount as set forth in the award documentation (the “Preferred Distribution”). These allocations are deducted before the calculation and distribution of the quarterly partnership distribution for the remaining partnership interests and are generally contingent upon services being provided by the unit holder. The Preferred Units are not entitled to participate in partnership distributions other than with respect to the Preferred Distribution. Preferred Units may not be made exchangeable into common stock and are only entitled to the Preferred Distribution, and accordingly they are not included in the fully diluted share count. The quarterly allocations of net income on Preferred Units are reflected the same as those of the LPUs described above in the Company’s consolidated statements of operations. After deduction of the Preferred Distribution, the remaining partnership interests generally receive quarterly allocations of net income based on their weighted-average pro-rata share of economic ownership of the operating subsidiaries .
Redeemable Partnership Interest	Redeemable Partnership Interest: Redeemable partnership interest represents limited partnership interests in BGC Holdings held by Founding/Working Partners. See Note 2—“Limited Partnership Interests in BGC Holdings and Newmark Holdings” for additional information related to the FPUs.
Contingent Class A Common Stock	Contingent Class A Common Stock: In connection with certain acquisitions, the Company committed to issue shares of the Company’s Class A common stock upon the achievement of certain performance targets. The contingent shares met the criteria for liability classification, are measured at fair value on a recurring basis and presented in “Accounts payable, accrued and other liabilities” in the Company’s consolidated statements of financial condition. Realized and unrealized gains (losses) resulting from changes in fair value are reported in “Other income (loss)” in the Company’s consolidated statements of operations.
Noncontrolling Interest in Subsidiaries	Noncontrolling Interest in Subsidiaries: Noncontrolling interest in subsidiaries represents equity interests in consolidated subsidiaries that are not attributable to the Company, such as Cantor units and the noncontrolling interest holders’ proportionate share of the profit or loss associated with joint ownership of the Company’s administrative services company in the U.K. (Tower Bridge).
Foreign Currency Transactions and Translation	Foreign Currency Transactions and Translation: Assets and liabilities denominated in nonfunctional currencies are converted at rates of exchange prevailing on the date of the Company’s consolidated statements of financial condition, and revenues and expenses are converted at average rates of exchange for the period. Gains and losses on remeasurement of foreign currency transactions denominated in nonfunctional
Derivative Financial Instruments	Derivative Financial Instruments: Derivative contracts are instruments, such as futures, forwards, options or swaps contracts, which derive their value from underlying assets, indices, reference rates or a combination of these factors. Derivative instruments may be listed and traded on an exchange, or they may be privately negotiated contracts, which are often referred to as OTC derivatives. Derivatives may involve future commitments to purchase or sell financial instruments or commodities, or to exchange currency or interest payment streams. The amounts exchanged are based on the specific terms of the contract with reference to specified rates, securities, commodities, currencies or indices.
