This Amendment No. 4 (this “Amendment”) amends the Schedule 13D, dated April 25, 2008 (the “Original 13D”), subsequently amended by Amendment No. 1 to the Original 13D, dated June 10, 2008 (“Amendment No. 1”), Amendment No. 2 to the Original 13D, dated December 1, 2008 (“Amendment No. 2”), and Amendment No. 3 to the Original 13D, dated January 30, 2009 (“Amendment No. 3”), filed by Cantor Fitzgerald, L.P., a Delaware limited partnership (“CFLP”), CF Group Management, Inc., a New York corporation (“CFGM”), and Howard W. Lutnick (together with CFLP and CFGM, the “Reporting Persons”). Capitalized terms not defined herein shall have the respective meanings ascribed to them in the Original 13D, Amendment No. 1, Amendment No. 2 or Amendment No. 3, as the case may be.

Item 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

Item 3 is hereby amended and supplemented by adding the following:

See Item 4, which is incorporated by reference herein.

Item 4. PURPOSE OF THE TRANSACTION.

Item 4 is hereby amended and supplemented by adding the following:

This Amendment No. 4 is being filed principally to reflect (i) an increase in the reportable beneficial ownership of shares of Class A Common Stock of the Reporting Persons as a result of the fact that the 67,138,052 BGC Holdings limited partnership units held by CFLP became exchangeable on March 31, 2009, (ii) an increase in the reportable beneficial ownership of shares of Class A Common Stock of the Reporting Persons (other than CFLP) and certain of the other persons listed on Schedule A to the Original 13D as a result of the fact that they or their designee were entitled to receive distribution rights shares on April 1, 2009, (iii) the fact that CFLP offered to its partners an opportunity to defer receipt of their distribution right shares until a later date and receive a distribution equivalent; (iv) the conversion on May 7, 2009 of 1,000,000 shares of Class B Common Stock into shares of Class A Common Stock and resulting transfer of 537,067 of such shares as distribution right shares to certain partners and former partners of CLFP; (v) an increase in the percentage ownership of the Reporting Persons as a result of the right to receive distribution rights shares and exchangeability of BGC Holdings limited partnership units, as well as a result of the revised number of outstanding shares of Class A Common Stock following certain repurchases of shares by the Company, and (vi) other matters relating to Item 4 of Schedule 13D.

In connection with the Separation, CFLP received 67,138,052 BGC Holdings limited partnership units. On March 31, 2009, the first anniversary of the completion of the Separation, all such BGC Holdings limited partnership units became exchangeable with the Company for shares of Class B Common Stock (or, at CFLP’s option, or if there are no additional authorized but unissued shares of Class B Common Stock, shares of Class A Common Stock) on a one-for-one basis (subject to customary anti-dilution adjustments). The Class B Common Stock is convertible at any time on a one-for-one basis (subject to customary anti-dilution adjustments) into Class A Common Stock. As of the date hereof, the Company had 58,500,000 shares of authorized but unissued Class B Common Stock.

After certain accelerated distributions of distribution rights shares described in Amendment No. 1 and Amendment No. 2, the aggregate number of shares of Class A Common Stock that CFLP was required to distribute to retained and founding partners was 26,145,740 shares (23,046,758 shares with respect to retained partners and 3,098,982 shares with respect to founding partners). The distribution rights provided to retained partners, including the Reporting Persons (other than CFLP) and certain other persons listed on Schedule A to the Original 13D, generally entitle the holder to receive a distribution of a fixed number of shares of Class A Common Stock from CFLP distributable in the following circumstances:

• with respect to distribution rights received in respect of CFLP limited partnership units, including units acquired at any time as a result of reinvestment in respect thereof, that were held three years or longer as of the completion of the Merger, one-third of the shares underlying the distribution rights on each of the 12-, 18- and 24-month anniversaries of the completion of the Merger; and

CUSIP No. 05541T 10 1 13D Page 6 of 17

• with respect to distribution rights received in respect of CFLP limited partnership units, including units acquired at any time as a result of reinvestment in respect thereof, that were held less than three years as of the completion of the Merger, one-fifth of the shares underlying the distribution rights on each of the 12-, 18-, 24-, 30- and 36-month anniversaries of the completion of the Merger,

in each case, if, as of the applicable anniversary date, that holder continues to provide services to CFLP and has not breached his, her or its CFLP partner obligations, including the non-competition and non-solicitation covenants contained in the limited partnership agreement of CFLP, to the extent applicable. The distribution rights provided by CFLP to founding partners entitle the holder to receive a fixed number of shares of Class A Common Stock from CFLP, with one-third of such shares distributable on each of the 12-, 24- and 36-month anniversaries of the completion of the Merger.

On April 1, 2009, the 12-month anniversary of the completion of the Merger, Cantor was required to distribute an aggregate of 6,317,385 shares of Class A Common Stock (5,872,888 shares with respect to retained partners and 444,497 shares with respect to founding partners) not including shares previously sold. In connection with the issuance of distribution rights shares, Cantor offered to its partners the opportunity to elect to defer their receipt of the distribution right shares until a later date and receive a distribution equivalent rather than making an immediate issuance of such shares in the form of Class A Common Stock. Cantor partners who elected to defer their right to such shares are entitled to exchange such partnership interests for shares of Class A Common Stock upon written notice. Exchanges will occur on such subsequent dates as shall be determined by Cantor in its administrative discretion and Cantor shall have a right to defer such exchanges for up to 3 months. Accordingly, of the 6,317,385 distribution rights shares to be distributed by Cantor in April 2009, partners having rights to 5,567,725 of such distribution rights shares elected to defer their receipt of shares. In May 2009, Cantor exchanged shares of Class B Common Stock and delivered 534,067 shares of Class A Common Stock in satisfaction of its distribution rights obligations effective April 1, 2009.

Upon completion of this distribution, the aggregate number of remaining shares of Class A Common Stock that Cantor will be required to distribute to retained and founding partners will be 25,611,673 shares of Class A Common Stock (22,812,582 shares with respect to retained partners and 2,799,091 shares with respect to founding partners).

Specifically, each of the Reporting Persons, which in the aggregate are entitled to receive 3,542,015 distribution rights shares, have indicated that they will defer receipt of their distribution rights shares until a later date and receive a distribution equivalent rather than receiving such distribution rights shares at the present time.

As noted above, retained partners, including the Reporting Persons (other than CFLP) and certain of the other persons listed on Schedule A to the Original 13D, are expected to receive distribution rights shares (or rights to receive distribution rights shares). The following table shows, the total number of distribution rights shares which may be received by each of the Reporting Persons (other than CFLP) and the other persons listed on Schedule A to the Original 13D and the number of distribution rights shares entitled to be received by each such person effective April 1, 2009:

(4) Of the 2,048,000 distribution rights shares, 682,667, 682,667 and 682,666 shares are expected to be receivable by KBCR on the 12-, 18- and 24-month anniversaries of the completion of the Merger, respectively.

In addition, three trusts for the benefit of Mr. Fraser’s children are expected to receive a total of 345,030 distribution rights shares, of which 115,010, 115,010 and 115,010 shares are expected to be receivable by the trusts on the 12-, 18-, and 24-month anniversaries of the completion of the Merger, respectively.

(6) After taking into account the 175,000 distribution rights shares received from CFLP on an accelerated basis and sold to the Company in June 2008, Mr. Merkel is expected to receive a total of 60,683 distribution rights shares, of which, 0, 6,736, 47,209, 3,369 and 3,369 shares are expected to be receivable by Mr. Merkel on the 12-, 18-, 24-, 30- and 36-month anniversaries of the completion of the Merger, respectively.

The Company may, from time to time, repurchase shares of its Class A Common Stock, including distribution rights shares, under its existing $100 million stock repurchase program or through future stock buyback or similar authorizations, including a tender offer or merger, which may be approved by its Audit Committee, including a 10b5-1 plan effected by a third-party broker or otherwise, and which could be material in amount. If the Reporting Persons do not participate in such repurchases by the Company,

CUSIP No. 05541T 10 1 13D Page 9 of 17

such repurchases will have the effect of increasing the Reporting Persons’ percentage ownership of the outstanding Class A Common Stock, because the repurchases will decrease the number of outstanding Class A Common Stock, but not decrease the Reporting Persons’ number of shares of Class A Common Stock. The Company has indicated that other than possible repurchases in connection with partnership terminations, it has no current plans to repurchase any of the distribution rights shares currently distributable in April 2009; however, such plans may change in the future.

As of May 31, 2009, the Company had approximately $32.4 million available under its original $100 million stock repurchase program for repurchases. In connection with its stock repurchase program, as of May 31, 2009, the Company had repurchased an aggregate of 4,023,959 shares of its Class A Common Stock for an aggregate purchase price of approximately $7.9 million during the first five months of 2009. From time to time, the Company has retained Cantor Fitzgerald & Co. as agent in connection with these purchases. In March 2009, as part of its existing stock repurchase program, the Company’s management was authorized to repurchase shares from all holders, including Cantor and its partners, employees and affiliates or The Cantor Fitzgerald Relief Fund. Included in these first quarter repurchases was a purchase on March 12, 2009 of an aggregate of 2,600,000 shares of Class A common stock by the Company at an aggregate price of $5,174,000 from The Cantor Fitzgerald Relief Fund, a portion of which shares had been donated by certain founding partners in connection with the 2008 Charity Day and a portion of which had been donated by one of the Reporting Persons.

As previously reported in the Original 13D, CFLP has the right to purchase from BGC Holdings any non-exchangeable BGC Holdings limited partnership units held by any founding partner that are redeemed by BGC Holdings upon termination or bankruptcy of the founding partner. Any such BGC Holdings limited partnership units purchased by CFLP from BGC Holdings will be exchangeable by CFLP for shares of Class B Common Stock or, at CFLP’s election, shares of Class A Common Stock, in each case on a one-for-one basis (subject to customary anti-dilution adjustments), from the Company, on the same basis as CFLP’s other BGC Holdings limited partnership units. As a result of the termination of an aggregate of 20 BGC Holdings founding partners since April 1, 2008, BGC Holdings has the right to redeem an aggregate of 1,272,060 BGC Holdings limited partnership units. To date, BGC Holdings has not redeemed any of the limited partnership units held by these 20 former founding partners. Upon the redemption of any of the founding partners’ BGC Holdings limited partnership units, CFLP will have the right to purchase from BGC Holdings an equivalent number of exchangeable BGC Holdings limited partnership units pursuant to terms yet to be determined.

On May 7, 2009, the Company issued an aggregate of 1,793,946 shares of Class A Common Stock to partners of BGC Holdings upon exchange of their exchangeable Founding Partnership Units. All of these shares are eligible for sale beginning on May 7, 2009 when the Company’s restrictions on employee stock transactions are lifted. In order to facilitate receipt of the shares by the partners of BGC Holdings and receipt of distribution rights shares to be received by partners of BGC Holdings and Cantor, the Company and Cantor have made arrangements for such partners to open brokerage accounts with an investment bank. These accounts will facilitate repayment by any such partners of any partnership loans or other amounts payable to Cantor or the Company.

The Reporting Persons evaluate each of their investments, including their investment in shares of Class A Common Stock and shares of Class B Common Stock in the Company (the “Shares”), on an ongoing basis, based upon various factors, criteria and alternatives including those noted below. Based on current circumstances and such ongoing evaluation, the Reporting Persons may, from time to time, acquire or seek to acquire additional Shares, continue to own Shares or dispose or seek to dispose of Shares at any time, in the open market or otherwise, and may take actions that could involve any of the items enumerated in the Schedule 13D instructions to this Item 4. Such acquisitions or dispositions may occur in the open market, through private purchases, by means of a tender offer, or an offer letter sent to the Company and its board of directors or otherwise, and may be effected with or without the participation of third parties. In addition, the Company may, from time to time, repurchase Shares under

CUSIP No. 05541T 10 1 13D Page 10 of 17

its existing $100 million stock repurchase program, by means of a future stock buyback, a tender offer, a merger or similar authorizations. Such repurchases could also have the effect of increasing the Reporting Persons’ percentage ownership of the outstanding Class A Common Stock.

The Reporting Persons reserve the right, based on all relevant factors and circumstances, to change their investment intent with respect to the Company and the Shares at any time in the future, and to change their intent with respect to any or all of the matters referred to in this Schedule 13D, including any of the items enumerated in the Schedule 13D instructions to this Item 4. In reaching any conclusion as to their future course of action, the Reporting Persons will take into consideration various factors, criteria and alternatives, including, but not limited to, the Company’s business and prospects, other developments concerning the business and management of the Company, its competitors and the industry in which it operates, other business and investment opportunities available to the Reporting Persons, any contractual obligations to which the Reporting Persons are now or may in the future become subject, including any contractual obligations with respect to its ownership of the Shares or otherwise relating to its investment in the Company or otherwise, and general economic and stock market conditions, including, but not limited to, the market price of the Shares and other investment alternatives. From time to time, the Reporting Persons may enter into discussions with the Company and/or third parties, concerning its holding of the Shares and possible future extraordinary transactions involving the Reporting Persons and the Company and such third persons. There can be no assurance as to whether the Reporting Persons will take any action with respect to its ownership of the Shares, take action with respect to any of the items enumerated in Item 4 of Schedule 13D, including entering into any discussions with the Company or with any third parties with respect to the Shares or the Company, nor as to outcome of any such matters, including as to whether any discussions if entered into will lead to any transaction that might be considered or agreed to by any third party, the Company or the Reporting Persons, the terms of any transaction, or the timing or certainty of any transaction.

Except as otherwise disclosed in this Item 4, the Reporting Persons do not currently have any agreements, beneficially or otherwise, that would be related to or would result in any of the matters described in Items 4(a)-(j) of Schedule 13D; however, as part of the ongoing evaluation of this investment and investment alternatives, including in connection with the possible acquisition or disposition of Shares, the Reporting Persons may consider such matters and, subject to applicable law, may formulate a plan with respect to such matters, and, from time to time, may hold discussions with or make formal proposals to management, the board of directors and/or the independent directors of the Company, or other third parties regarding such matters.

Item 5. INTEREST IN SECURITIES OF THE ISSUER.

Item 5 is hereby amended and restated in its entirety as follows:

On April 1, 2009, the 12-month anniversary of the completion of the Merger, Cantor was required to distribute an aggregate of 6,317,385 shares of Class A Common Stock (5,872,888 shares with respect to retained partners and 444,497 shares with respect to founding partners), some which CFLP partners elected to defer receipt of their shares. The information in this Item 5 is provided as of the date of this filing (except for the number of shares of Class A Common Stock held in Mr. Lutnick’s and Mr. Merkel’s respective 401(k) accounts, which is provided as of May 29, 2009):

CFLP is the beneficial owner of, and has shared voting and dispositive power with respect to, (i) 622,890 shares of Class A Common Stock owned of record by it, (ii) 29,099,362 shares of Class A Common Stock receivable upon conversion of 29,099,362 shares of Class B Common Stock owned of record by it, and (iii) 67,138,052 shares of Class A Common Stock receivable upon exchange of 67,138,052 BGC Holdings exchangeable limited partnership units (or, upon conversion of 67,138,052 shares of Class B Common Stock receivable upon exchange of 67,138,052 BGC Holdings exchangeable
