("CFGM"), (ii) 2,210,872 shares represented by deferred stock distributions receivable by CFGM (consisting of 2,050,197 shares subject to deferred stock distribution obligations provided to certain current and former partners of CFLP on April 1, 2008 (the "April 2008 deferred stock distribution obligations") and 160,675 shares subject to deferred stock distribution obligations provided to partners of CFLP on February 14, 2012 (the "February 2012 deferred stock distribution obligations"), continued in footnote 3 ( 3 )(iii) 5,315,560 shares of Class A common stock held in various trust, retirement and custodial accounts ((A) 4,268,455 shares held in the reporting person's personal asset trust, of which the reporting person is sole trustee, (B) 246,931 shares held by a trust (the "Trust") for the benefit of the descendants of the reporting person and his immediate family, of which the reporting person's spouse is one of two trustees and the reporting person has limited powers to remove and replace such trustees, (C) 147,359 shares held in a Keogh retirement account for the reporting person, (D) 609,478 shares held by trust accounts for the benefit of the reporting person and members of his immediate family, (E) 29,635 shares held in other retirement accounts, and (F) 13,702 shares held in custodial accounts for the benefit of certain members of the reporting person's family under the Uniform Gifts to Minors Act), (continue to footnote 4) ( 4 )(iv) 1,610,182 shares represented by April 2008 deferred stock distribution obligations receivable by the Trust, (v) 26,052 shares represented by deferred stock distributions receivable by the reporting person's spouse (consisting of 23,780 shares subject to April 2008 deferred stock distribution obligations and 2,272 shares subject to February 2012 deferred stock distribution obligations), (continued in footnote 5) ( 5 )(vi) 2,335,967 shares represented by deferred stock distributions receivable by KBCR Management Partners, LLC ("KBCR") (consisting of 2,048,000 shares subject to April 2008 deferred stock distribution obligations and 287,967 shares subject to February 2012 deferred stock distribution obligations, and (vii) 384,267 shares held in the reporting person's 401(k) account as of March 31, 2015 ( 6 )Does not include an aggregate of 1,316,883 shares of Class A Common Stock acquired by CFLP upon exercise of exchange rights with respect to 1,316,883 exchangeable limited partnership interests in BGC Holdings, L.P., because such aggregate 1,316,883 shares of Class A Common Stock were assumed in previous reports to have been distributed in connection with CFLP's deferred stock distribution obligations.
