NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

On April 1, 2008, BGC Partners, LLC merged with and into eSpeed, Inc. (“eSpeed”), which survived the merger and was renamed BGC Partners, Inc. (“BGC Partners,” “BGC” or the “Company”). In the merger, an aggregate of 133,860,000 shares of common stock and rights to acquire shares of BGC Partners were issued. Of these, 56,000,000 were in the form of Class B Common Stock or rights to acquire Class B Common Stock, and the remaining 77,860,000 were in the form of Class A Common Stock or rights to acquire Class A Common Stock. Stockholders of eSpeed held the same number and class of shares of BGC Partners common stock immediately after the merger that they held in eSpeed immediately prior to the merger. BGC Partners’ Class A Common Stock trades on the NASDAQ Global Market under the symbol “BGCP.”

The merger has been accounted for as a combination of entities under common control. eSpeed was deemed the acquirer and BGC Partners, LLC was deemed the acquiree. According to Statement of Financial Accounting Standards (“SFAS”) No. 141, Business Combinations, since the merger was a transaction between entities under common control, the assets and liabilities of BGC Partners, LLC were transferred at historical cost and the results of operations and cash flows have been reflected in the accompanying unaudited condensed consolidated financial statements as if the merger occurred as of the earliest period presented.

The Company’s unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted from this report as is permitted by SEC rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. The accompanying unaudited condensed consolidated financial statements contain all normal and recurring adjustments that, in the opinion of management, are necessary for a fair presentation of the Condensed Consolidated Statements of Financial Condition, the Condensed Consolidated Statements of Operations and the Condensed Consolidated Statements of Cash Flows of the Company for the interim periods presented. These unaudited condensed consolidated financial statements reflect the historical financial position, results of financial operations and cash flows of BGC Partners as if the merger occurred as of the earliest period presented, with the exception of certain capital and tax modifications which became effective as of April 1, 2008. Specifically, the historical financial statements of BGC Partners, for the periods prior to April 1, 2008, do not give effect to the following matters, which are described in more detail in Note 2, The Separation, Merger and Recapitalization, Note 3, Tax Restructuring and Note 4, Earnings Per Share:

Recently Adopted Accounting Pronouncements:

SFAS No. 157: In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements (“SFAS 157”). SFAS 157 clarifies that fair value is the amount that would be exchanged to sell an asset or transfer a liability, in an orderly transaction between market participants. SFAS 157 nullifies the consensus reached in EITF Issue No. 02-3 prohibiting the recognition of day-one gain or loss on derivative contracts where the firm cannot verify all of the significant model inputs to observable market data and verify the model to market transactions. However, SFAS 157 requires that a fair value measurement technique include an adjustment for risks inherent in a particular valuation technique (such as a pricing model) and/or the risks inherent in the inputs to the model, if market participants would also include such an adjustment. In addition, SFAS 157 prohibits the recognition of block discounts for large holdings of unrestricted financial instruments where quoted prices are readily and regularly available in an active market. The provisions of SFAS 157 are to be applied prospectively, except for changes in fair value measurements that result from the initial application of SFAS 157 to existing derivative financial instruments measured under EITF Issue No. 02-3, existing hybrid instruments measured at fair value and block discounts, which are to be recorded as an adjustment to opening retained earnings in the year of adoption. The Company adopted the provisions of SFAS 157 when they became effective on January 1, 2008.

SFAS 157 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 under SFAS 157 are as follows:

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 its financial instruments owned and its financial instruments sold, but not yet purchased into two categories: cash instruments and derivative contracts.

Table of Contents

The types of instruments valued based on quoted prices in markets that are not active, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency include most investment-grade and high-yield corporate bonds, certain sovereign government obligations, money market securities, and less liquid listed equities, state, municipal and provincial obligations. Such instruments are generally classified within Level 2 of the fair value hierarchy.

See Note 5 for further information on SFAS 157.

SFAS No. 159: In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Liabilities (“SFAS 159”). SFAS 159 provides companies with an option to report selected financial assets and liabilities at fair value, and establishes presentation and disclosure requirements designed to facilitate comparisons between companies that choose different measurement attributes for similar types of assets and liabilities. SFAS 159 is effective for the Company as of January 1, 2008. On January 1, 2008, the Company adopted the fair value option for its available-for-sale securities. The change in fair value of these instruments is recorded in Principal transactions. As a result, the related unrealized loss of approximately $61,000 for the year ended December 31, 2007 was reclassified from Accumulated other comprehensive loss to beginning Retained deficit, as a cumulative effect adjustment.

New Accounting Pronouncements:

SFAS No. 141(R): In December 2007, the FASB issued SFAS No. 141(R), Business Combinations (“SFAS 141(R)”). SFAS 141(R) replaces SFAS 141, Business Combinations. SFAS 141(R) retains the fundamental requirements in SFAS 141 that the acquisition method of accounting be used for all business combinations and for an acquirer to be identified for each business combination. SFAS 141(R) amends the recognition provisions for assets and liabilities acquired in a business combination, including those arising from contractual and non-contractual contingencies. SFAS 141(R) also amends the recognition criteria for contingent consideration. SFAS 141(R) is effective as of January 1, 2009. Early adoption is not permitted. The Company is currently evaluating the potential impact of adopting SFAS 141(R) on its consolidated financial statements.

SFAS No. 160: In December 2007, the FASB issued SFAS No. 160, Non-controlling Interest in Consolidated Financial Statements—an amendment to ARB No. 51 (“SFAS 160”). SFAS 160 amends ARB 51 to establish accounting and reporting standards for the non-controlling interest in a subsidiary and for the deconsolidation of a subsidiary. It clarifies that a non-controlling interest in a subsidiary is an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements. SFAS 160 also requires consolidated net income to be reported at amounts that include the amounts attributable to both the parent and the non-controlling interest. It also requires disclosure, on the face of the consolidated statement of income, of the amounts of consolidated net income attributable to the parent and to the non-controlling interest. SFAS 160 is effective as of January 1, 2009. Early adoption is not permitted. The Company is currently evaluating the potential impact of adopting SFAS 160.

Table of Contents

SFAS No. 161: In March 2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities (“SFAS 161”). SFAS 161 requires enhanced disclosures about an entity’s derivative and hedging activities and thereby improves the transparency of financial reporting. Entities are required to provide enhanced disclosures about (a) how and why an entity uses derivative instruments, (b) how derivative instruments and related hedged items are accounted for under Statement 133 and its related interpretations and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance and cash flow. SFAS 161 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008, with early adoption encouraged. SFAS 161 encourages, but does not require, comparative disclosures for earlier periods at initial adoption. The Company is currently evaluating the potential impact of adopting SFAS 161.

FASB Staff Position (“FSP”) No. 142-3:  In April 2008, the FASB issued FSP 142-3, Determining the Useful Life of Intangible Assets (“FSP 142-3”). FSP 142-3 amends the factors to be considered in determining the useful life of intangible assets. Its intent is to improve the consistency between the useful life of an intangible asset and the period of expected cash flows used to measure such asset’s fair value. FSP 142-3 is effective for fiscal years beginning after December 15, 2008. The Company is currently evaluating the potential impact of adopting FSP 142-3.

SFAS No. 162: In May 2008, the FASB issued SFAS No. 162, The Hierarchy of Generally Accepted Accounting Principles (“SFAS 162”). SFAS 162 identifies the sources of accounting principles and the framework for selecting the principles to be used in the preparation of financial statements of nongovernmental entities that are presented in conformity with generally accepted accounting principles in the United States. It is effective 60 days following the SEC’s approval of the Public Company Accounting Oversight Board amendments to AU Section 411, “The Meaning of Present Fairly in Conformity With Generally Accepted Accounting Principles ”. The Company is currently evaluating the potential impact of adopting SFAS 162.

FASB Staff Position (“FSP”) No. EITF 03-6-1: In June 2008, the FASB issued FSP EITF No. 03-6-1, Determining Whether Instruments Granted in Share-Based Payment Transactions Are Participating Securities (“EITF 03-6-1”), which addresses whether instruments granted in share-based payment transactions are participating securities prior to vesting and therefore need to be included in the earnings allocation in calculating earnings per share under the two-class method described in SFAS No. 128, Earnings per Share . EITF 03-6-1 requires companies to treat unvested share-based payment awards that have non-forfeitable rights to dividend or dividend equivalents as a separate class of securities in calculating earnings per share. EITF 03-6-1 is effective for fiscal years beginning after December 15, 2008. Early adoption is not permitted. The Company is currently evaluating the potential impact of adopting EITF 03-6-1.

The Separation

On March 31, 2008, Cantor contributed the businesses of its inter-dealer brokerage business, known as the BGC Division, to BGC Partners, LLC and its subsidiaries. As part of the separation, two operating partnerships, BGC Partners, L.P. (“BGC US”) and BGC Global Holdings, L.P. (“BGC Global”), were established as wholly-owned subsidiaries of BGC Holdings, L.P. (“BGC Holdings”), a wholly-owned subsidiary of BGC Partners, LLC.

In connection with the separation, Cantor redeemed certain limited partnership interests in Cantor held by certain of its limited partners for limited partnership interests in BGC Holdings and rights to receive, following the merger, distributions of the Company’s stock owned by Cantor. The limited partnership interests in BGC Holdings issued at the separation are referred to as founding partner interests.

Table of Contents

The Merger

On April 1, 2008, BGC Partners, LLC merged with and into eSpeed to form BGC Partners. In connection with the merger, eSpeed contributed its assets and liabilities to BGC US and BGC Global in exchange for limited partnership interests in these entities.

As a result of the separation and merger, the following four economic ownership classes of the Company were established:

Founding/working partners

Founding/working partners have a limited partnership interest in BGC Holdings. Prior to the merger, this interest was accounted for as a component of stockholders’ and members’ equity section of the Condensed Consolidated Statements of Financial Condition. With effect from the merger, the Company accounts for founding/working partnership interest outside of permanent capital, as “Redeemable partnership interest”, in the Condensed Consolidated Statements of Financial Condition. This classification is in accordance with EITF Topic D-98, Classification and Measurement of Redeemable Securities (“EITF D-98”), which requires that preferred securities, or other equity instruments, including common stock, derivative instruments, noncontrolling interests, and share-based payment arrangements that are classified as equity, that are redeemable for cash or other assets are to be classified outside of permanent equity if they are redeemable (1) at a fixed or determinable price on a fixed or determinable date, (2) at the option of the holder, or (3) upon the occurrence of an event that is not solely within the control of the issuer. EITF D-98 is applicable to founding/working partners’ interest because founding/working partner units are redeemable upon termination of a partner, which includes the termination of employment, which can be at the option of the partner and not within the control of the issuer.

Additionally, founding/working partners units receive allocations of net income based on their pro rata share of economic ownership. This allocation is reflected as “Allocation of net income to founding/working partners units” in the Company’s Condensed Consolidated Statements of Operations, which is a separate component of compensation expense.

REUs

In connection with the merger, BGC Holdings issued REUs to certain of its limited partners. The REUs entitle the holder to participate in distributions of BGC Holdings’ income and to receive post-termination payments equal to the notional value of the grant in four equal yearly installments after the holder’s termination. At the Company’s discretion, the REUs may also be exchangeable for Class A Common Stock on a one-for-one basis. The allocation of income to REUs is reflected as “Allocation of net income to REUs” in the Company’s Condensed Consolidated Statements of Operations, which is a separate component of compensation expense.

Cantor

Cantor’s limited partnership interest in BGC Holdings as a result of its contribution of the BGC Division is reflected as a component of “Minority interest” on the Company’s Condensed Consolidated Statements of Financial Condition. Cantor receives allocations of net income based on its pro rata share of economic ownership. This allocation is reflected as a component of “Minority interest” in the Company’s Condensed Consolidated Statements of Operations.

Common stockholders

Common stockholders’ interest is the interest held by the public, including Cantor, in the form of Class A and Class B Common Stock. This interest is reflected as “Stockholders’ equity” in the Company’s Condensed Consolidated Statements of Financial Condition.

Primary and Secondary Offerings

On June 10, 2008, the Company closed an underwritten public offering of additional shares of its Class A Common Stock (the “June 2008 Offering”). The offering was composed of a primary offering (the “Primary Offering”) of 10,000,000 newly issued shares offered by the Company and a secondary offering (the “Secondary Offering”) of 10,000,000 issued and outstanding shares offered by Cantor and certain limited partners of Cantor and founding partners of BGC Holdings (“the Selling Stockholders”). In the Secondary Offering, 3,926,178 shares were offered by Cantor and 6,073,822 shares were offered by certain limited partners of Cantor and founding partners of BGC Holdings.

The offering price to the public was $8.00 per share, and the price, net of underwriters’ discount of 3.5%, was $7.72 per share. The Company received net proceeds of $77.2 million as a result of the Primary Offering. Offering expenses, other than underwriters’ discounts, of approximately $4.9 million were incurred by the Company. The Company did not receive any net proceeds from the sales of common stock offered by the Selling Stockholders in the Secondary Offering. The Company and Cantor, as a selling stockholder, granted the underwriters an option, exercisable not later than 30 days after June 5, 2008, to purchase up to 3,000,000 additional shares of Class A Common Stock at a price of $7.72 per share. The option shares were to be sold by the Company or Cantor, or a combination thereof, at the Company’s election, however, the underwriters did not exercise this option.

Immediately following the Primary Offering, the Company repurchased 175,000 shares of Class A Common Stock from one of its executive officers for $7.72 per share, totaling approximately $1.4 million. BGC Partners contributed the remaining net proceeds from the Primary Offering to BGC US and BGC Global in exchange for additional partnership interests on a one-for-one basis. BGC US and BGC Global expect to use such proceeds for general corporate purposes, including potential acquisitions.

eSpeed was a U.S. corporation and reported and paid U.S. federal income taxes as well as taxes to other jurisdictions in which it or its subsidiaries conducted business. Historically, much of BGC Partners, LLC had operated through entities that were treated as partnerships for U.S. federal income tax purposes. As such, much of the income was not subject to U.S. federal and state income taxes because taxes related to income earned by partnerships represent obligations of the individual partners. BGC Partners, LLC did have certain companies that were incorporated and subject to U.S. federal, state and local income tax and they did report and pay U.S. federal, state and local income taxes. Outside the United States, BGC Partners, LLC had operated principally through subsidiary corporations subject to local income taxes. Prior to April 1, 2008, income taxes reported on the consolidated financial statements for BGC Partners, LLC were primarily attributable to taxes incurred by its incorporated U.S. entities and by non-U.S. entities. Subsequent to the merger, the consolidated financial statements of the Company include U.S. federal, state and local income taxes on its allocable share of the U.S. results of operations, giving effect to the post-merger structure, as well as taxes payable to jurisdictions outside the U.S.

Income taxes are accounted for using the asset and liability method, as prescribed in SFAS No. 109, Accounting for Income Taxes (“SFAS 109”). Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the 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 more likely than not those assets will not be realized. No deferred U.S. federal income taxes have been provided for the undistributed foreign corporate earnings since they have been permanently reinvested in the Company’s foreign operations. It is not practical to determine the amount of additional tax that may be

payable in the event these earnings are repatriated. Effective January 1, 2007, the Company, adopted Financial Accounting Standards Board Interpretation No. 48, Accounting For Uncertainty in Income Taxes—an interpretation of SFAS No. 109 (“FIN 48”). It is the Company’s policy to provide for uncertain tax positions and the related interest and penalties based upon management’s assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities.

SFAS No. 128, Earnings Per Share (“SFAS 128”), establishes standards for computing and presenting earnings per share (“EPS”). SFAS 128 requires the dual presentation of basic and diluted EPS on the face of the accompanying Condensed Consolidated Statement of Operations and requires a reconciliation of numerators (net income (loss)) and denominators (weighted-average shares of common stock outstanding) for both basic and diluted EPS in the footnotes. Basic EPS excludes dilution and is computed by dividing net income (loss) available to common stockholders by the weighted-average shares of common stock outstanding. From April 1, 2008, net income is allocated to each of the four economic ownership classes described above, based on each class’s pro rata economic ownership. The weighted-average shares of common stock outstanding have been retroactively restated to all periods prior to April 1, 2008 to give effect to the shares issued in connection with the merger. There were no net income allocations to founding/working partners units, REUs, or Cantor for the periods prior to April 1, 2008 as it is assumed that all of the Company’s net income (loss) for those periods was allocated to all economic owners, including common stockholders.

The Company’s earnings for the three months and nine months ended September 30, 2008 and 2007 were allocated as follows (in thousands):

The following is information pertaining to the Company’s basic earnings per share (in thousands, except for per share data):

15

Table of Contents

Fully diluted earnings (loss) per share is calculated utilizing net income available for common stockholders plus net income allocations to the founding/working partners units, REUs, and Cantor; and dividing it by the weighted average number of BGC Holdings units held by founding/working partners and Cantor, the Company’s outstanding shares of common stock, and the potential dilution that could occur if securities or other contracts to issue shares of common stock, including REUs, options, restricted stock units (“RSUs”) and warrants, were exercised, resulting in the issuance of shares of common stock that would then share in earnings in the Company’s net income available to common stockholders. The following is information pertaining to the Company’s fully diluted earnings (loss) per share (in thousands, except for per share data):

For the three months ended September 30, 2008 and 2007, approximately 22.4 million and 17.0 million REUs, options, RSUs and warrants, respectively, were not included in the computation of diluted earnings (loss) per share because their effect would have been anti-dilutive because the exercise price exceeded the average share price for the period. For the nine months ended September 30, 2008 and 2007, approximately 21.2 million and 16.9 million REUs, options, RSUs and warrants, respectively, were not included in the computation of diluted earnings (loss) per share because their effect would have been anti-dilutive because the exercise price exceeded the average share price for the period.

Table of Contents

During the nine months ended September 30, 2008, under this plan, the Company repurchased 3,163,072 shares of its Class A Common Stock for an aggregate purchase price of approximately $15.3 million. These repurchases included 1,261,491 shares repurchased from certain limited partners of BGC Holdings and Cantor on September 22, 2008 at a price of $4.00 per share, for an aggregate purchase price of approximately $5.0 million.

The 1,261,491 shares were purchased as follows: (i) 198,487 shares were purchased from partners of Cantor, which shares were transferred pursuant to distribution rights from Cantor in connection with the separation and merger of BGC Partners; (ii) 259,882 shares were purchased from founding partners of BGC Holdings, which shares were transferred to them pursuant to distribution rights from Cantor in connection with the separation and merger; and (iii) 803,122 shares were purchased from founding partners of BGC Partners and were issued upon exchange of exchangeable Founding Partner Units in BGC Holdings that such founding partners received in connection with the separation and merger.

In connection with the stock repurchase, Cantor agreed to accelerate the distribution of the distribution rights solely to permit such partners to sell such shares to the Company. The Company, as the general partner of BGC Holdings, further removed the contractual resale restrictions on such shares solely to permit such founding partners to sell such shares to the Company.

At September 30, 2008, the Company had approximately $43.0 million remaining from its $100.0 million buyback authorization.

The following table sets forth the Company’s financial assets, including those pledged as collateral, and financial liabilities at fair value (in thousands):

Securities purchased under agreements to resell (“Reverse Repurchase Agreements”) are accounted for as collateralized financing transactions and are recorded at the contractual amount for which the securities will be resold including accrued interest.

For Reverse Repurchase Agreements, it is the Company’s policy to obtain possession of collateral with a market value equal to or in excess of the principal amount loaned under Reverse Repurchase Agreements. Collateral is valued daily and the Company may require counterparties to deposit additional collateral or return collateral pledged when appropriate. Certain Reverse Repurchase Agreements are with Cantor (see Note 10, Related Party Transactions, for more information regarding these agreements).

As of September 30, 2008, the Company had received, as collateral, U.S. Government, agency and equity securities with a fair value of $210.9 million, of which $204.5 million pertained to Reverse Repurchase Agreements with Cantor. Of the securities received as collateral, securities with a fair value of $28.8 million were repledged to exchanges or clearing organizations to fulfill deposit requirements and $60.2 million was used to cover settlement of principal transactions.

As of December 31, 2007, the Company had received, as collateral, U.S. Government and agency securities with a fair value of $150.7 million, of which $143.2 million pertained to Reverse Repurchase Agreements with Cantor. Of the securities received as collateral, securities with a fair value of $28.3 million were repledged to exchanges or clearing organizations to fulfill deposit requirements.

Receivables from and payables to brokers, dealers, clearing organizations, customers and related broker-dealers primarily represent amounts due for undelivered securities, amounts related to open derivative contracts, 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.

The receivables from and payables to brokers, dealers, clearing organizations, customers and related broker-dealers consisted of the following (in thousands):

A portion of these receivables and payables is with Cantor (see Note 10, Related Party Transactions, for additional information related to these receivables and payables).

Substantially all open fails to deliver and fails to receive transactions as of September 30, 2008 have subsequently settled at the contracted amounts.

The Company has both OTC and exchange-traded derivative contracts. These derivative contracts primarily consist of bond futures, commodities, interest rate and foreign exchange futures, options, forwards and swaps. The Company enters into derivative contracts to facilitate client transactions, to hedge principal positions and to facilitate hedging activities of affiliated companies. Open derivative contracts are recognized at the fair value of the related assets and liabilities as part of “Receivables from and Payables to brokers, dealers, clearing organizations, customers and related broker dealers” in the accompanying Condensed Consolidated Statements of Financial Condition.

Fair values of derivative contracts are determined from quoted market prices or other public price sources. The Company does not designate any derivative contracts as hedges for accounting purposes. The change in fair value of derivative contracts is reported as part of “Principal transactions” in the accompanying Condensed Consolidated Statements of Operations.

The fair value of derivative financial instruments, computed in accordance with the Company’s netting policy, is set forth below (in thousands):

Transactions with off-balance-sheet risk are primarily short-term in duration.

Administrative Services Agreements

In the United States, Cantor provides the Company with administrative services and other support for which Cantor charges the Company based on the cost to Cantor of providing such services. Such support includes allocations for occupancy of office space, utilization of fixed assets and accounting, operations, human resources and legal services. On April 1, 2008, in connection with the services Cantor provides, the Company and Cantor entered into an employee lease agreement whereby certain employees of Cantor are deemed leased employees of the Company, and the Company has the powers and rights of a common law employer of such employees.

The fees paid to 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 accompanying Condensed Consolidated Statements of Operations. The fees paid to Cantor to cover the compensation costs of leased employees are included as part of “Compensation and employee benefits” in the accompanying Condensed Consolidated Statements of Operations.

For the three months ended September 30, 2008, the Company was charged $7.6 million for the services provided by Cantor and its affiliates, of which $4.7 million was to cover compensation to leased employees. For the three months ended September 30, 2007, the Company was charged $10.1 million for the services provided by Cantor and its affiliates. For the nine months ended September 30, 2008, the Company was charged $22.1 million for the services provided by Cantor, of which $9.5 million was to cover compensation to leased employees. For the nine months ended September 30, 2007, the Company was charged $21.1 million for the services provided by Cantor.

Throughout Europe and Asia, the Company provides Cantor with administrative services and other support for which the Company charges Cantor based on the cost of providing such services plus a mark-up, currently 7.5%. Such support includes allocations for occupancy of office space, utilization of fixed assets, accounting, operations, human resources and legal services. In the UK, the Company provides these services to Cantor through Tower Bridge International Services L.P. (“Tower Bridge”). The Company established Tower Bridge on December 21, 2006, and as of the beginning of January 2007, transferred all of its current UK administrative employees and operations to Tower Bridge.
