The Issuer's Class A Shares are traded on the New York Stock Exchange under the symbol "GBL".  Mario J. Gabelli ("Mario Gabelli") is deemed to be the controlling person of the Issuer on the basis of his ownership of a majority of the voting stock and the capital stock of GGCP, Inc. ("GGCP"), a privately held Wyoming corporation, which through GGCP Holdings, LLC ("GGCP Holdings") owns a majority of the voting stock and a majority of the capital stock of the Issuer.

Item 2.                                        Identity and Background

(a), (b) and (c) - This statement is being filed by one or more of the following persons: Gabelli Foundation, Inc. ("Foundation"), GGCP, GGCP Holdings, and Mario Gabelli.  Those of the foregoing persons signing this Schedule 13D are hereinafter referred to as the "Reporting Persons".
GGCP makes investments for its own account and is the managing member and holder of a majority of the equity interest of GGCP Holdings.  The Issuer is the parent company for a variety of companies engaged in the securities business including the management of registered investment companies, separately managed accounts and privately offered funds.
Mario Gabelli is the Chairman, Chief Executive Officer, Chief Investment Officer and controlling shareholder of the Issuer.  Mario Gabelli is also the controlling stockholder, Chief Executive Officer and a director of GGCP.    Mario Gabelli is also a member of GGCP Holdings and has a profits interest in GGCP Holdings.
The Foundation is a private foundation.  Mario Gabelli is the Chairman, a Trustee and the Investment Manager of the Foundation.
The Reporting Persons do not admit that they constitute a group.
The business address of Mario Gabelli is GAMCO Investors, Inc., One Corporate Center, Rye, NY 10580.  GGCP is a Wyoming corporation having its principal business office at 140 Greenwich Avenue, Greenwich, CT 06830.   GGCP Holdings is a Delaware limited liability company having its principal business office at 140 Greenwich Avenue, Greenwich, CT 06830.
                                For information required by instruction C to Schedule 13D with respect to the executive officers and directors of the foregoing entities (collectively, "Covered Persons"), reference is made to Schedule I annexed hereto and incorporated herein by reference.
               (d) - Not applicable.
               (e) – Not applicable.
                                               (f) – Each Reporting Person is a citizen of the United States.

Item 3.                              Source and Amount of Funds or Other Consideration
No funds were used in association with the reported action.

Item 4.                   Purpose of Transaction

               On February 5, 2013, the Board of Directors of the Issuer adopted a resolution permitting GGCP or its shareholders to exchange an additional 1,200,000 of the Issuer's Class B Common Stock ("Class B Shares") of the Issuer for an equal number of shares of Class A Shares of the Issuer as long as there are sufficient authorized but unissued Class A Shares unreserved for issuance.
               As a result of the above transaction, a total of 855,086 Class A Shares remain available to be issued upon exchange for Class A Shares by Mario Gabelli, GGCP Holdings, GGCP, or GGCP's shareholders.  The Class A Shares and the Class B Shares are identical in all respects except that holders of the Class A Shares are entitled to one vote per share and holders of the Class B Shares are entitled to ten votes per share.
               Mario Gabelli serves as the Chief Executive Officer and Chairman of the Board of Directors of the Issuer. As disclosed in Item 1 above, Mr. Gabelli is also deemed to be the control person of the Issuer.   Because of the foregoing, the Reporting Persons at any time and from time to time in the ordinary course of performing their roles relating to the Issuer or as investors in the Issuer may propose or take action in relation to the business of the Issuer including: changes in the present board of directors or management of the issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board; the business and operations of the Issuer; share repurchases by the Issuer; distributions by the Issuer, including the amounts, makeup and timing thereof; the terms of any new issuances of an existing or new class of securities by the Issuer; sales of assets; changes in the Issuer's charter or by-laws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person; and any such other matters.  Any such proposals or actions by the Reporting Persons may be  based on the Reporting Persons' views of their best interest, their obligations to the Issuer (to the extent required by applicable law or agreement), and other factors in light of (i) the Issuer's financial position, future actions taken by the Issuer's Board, price levels of the common stock or other equity or debt securities of the Issuer and (ii) general economic, political, or industry conditions, including conditions in the securities market, or changes in laws, rules, regulations or customs, and any other conditions or changes thereto, in the Reporting Persons' sole determination.  In as much as none of these proposals or activities would represent a material change in the plans of the Reporting Persons regarding their control over the Issuer, the Reporting Persons will not file amendments to this Schedule 13D reflective thereof.
                   The Reporting Persons intend to review their investments in the Issuer on a continuing basis and depending on various factors the Reporting Persons may deem relevant to their investment decision, including, without limitation, the Issuer's financial position and strategic direction, the price levels of the Shares, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may decide to acquire additional Securities, sell some or all of their Securities, or to continue to hold their existing position in the Securities for investment.
                    Other than as described above, none of the Reporting Persons has any present plans or proposals which related to or would result in any transaction, change or event specified in clauses (a) through (j) of Item 4 of Schedule 13D.

Item 5.                                        Interest in Securities of the Issuer
                             (a) The aggregate number of Securities to which this Schedule 13D relates is 899,086 Class A Shares, representing 12.12% of the 7,418,143 Class A Shares outstanding as of October 17, 2014 according to the Issuer's records and assuming the Reporting Persons exchange 855,086 of their Class B Shares for Class A Shares.
