Blackstone Holdings III’s payment of the aggregate purchase price was funded by cash on hand.

Item 4. Purpose of Transaction.

The shares of Common Stock held by Blackstone Holdings III were acquired as described in Item 6. Blackstone Holdings III currently holds such shares for investment purposes, subject to the following.

The Reporting Persons intend to review on a continuing basis Blackstone Holdings III’s investment in the Issuer. As a result of the Reporting Persons’ continuous review and evaluation of the business of the Issuer, the Reporting Persons may communicate with the board of directors of the Issuer, members of management and/or other stockholders from time to time with respect to operational, strategic, financial or governance matters or otherwise work with management and the board of directors with a view to maximizing stockholder value. Subject to the agreements described herein, the Reporting Persons may seek to sell or otherwise dispose of some or all of the Issuer’s securities (which may include, but is not limited to, transferring some or all of such securities to its affiliates or distributing some or all of such securities to such Reporting Person’s respective partners, members or beneficiaries, as applicable) from time to time, and/or may seek to acquire additional securities of the Issuer (which may include rights or securities exercisable or convertible into securities of the Issuer) from time to time, in each case, in open market or private transactions, block sales or otherwise. Any transaction that the Reporting Persons may pursue may be made at any time and from time to time without prior notice and will depend on a variety of factors, including, without limitation, the price and availability of the Issuer’s securities, subsequent developments affecting the Issuer, the Issuer’s business and the Issuer’s prospects, other investment and business opportunities available to the Reporting Persons, general industry and economic conditions, the securities markets in general, tax considerations and other factors deemed relevant by the Reporting Persons.

In connection with the purchase of the Issuer’s Common Stock pursuant to the Purchase Agreement and the Assignment Agreement (each as defined below), Blackstone Holdings III was granted the right to designate two individuals for election to the Issuer’s board of directors, one of whom will be appointed as chairman of the board of directors of the Issuer. In addition, the Issuer is, subject to the Maryland General Corporation Law and the rules of the New York Stock Exchange, required to ensure that the board of directors has no more than 8 directors unless Blackstone Holdings III agrees to such increase in writing. Blackstone Holdings III also has the right to proportionate representation on any committees of the board of directors of the Issuer. These rights and obligations will last as long as the Blackstone Entities or their affiliates collectively beneficially own at least 50% of the Common Stock issued to the Blackstone Entities pursuant to the Purchase Agreement (i.e., the 5,000,000 shares of Common Stock purchased by Blackstone Holdings III as described in Item 6 of this Schedule 13D, as adjusted for certain stock splits, reverse stock splits or any other similar events). As of the closing of the transactions contemplated by the Purchase Agreement (the “Closing”),

9

John G. Schreiber and Michael B. Nash were appointed to serve on the board of directors of the Issuer (with John G. Schreiber appointed to serve as the chairman of the board) and in such capacities, may have influence over the corporate activities of the Issuer, including activities which may relate to items described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

In addition, in connection with the Closing, an affiliate of the Blackstone Entities entered into a management agreement (the “Management Agreement”) with the Issuer pursuant to which such affiliate entity, BREDS / CT Advisors L.L.C., agreed to manage the day-to-day operations and activities and certain strategic and other plans and proposals of the Issuer. BREDS / CT Advisors L.L.C., in its capacity as manager, may have direct or indirect influence over such corporate activities of the Issuer, including activities which may relate to items described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

Except as described in this Item 4 of Schedule 13D, including with regards to certain of its affiliates and employees pursuant to the Management Agreement, the Reporting Persons do not have any present plans or proposals that relate to or would result in any of the actions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D, although, subject to the agreements described herein, the Reporting Persons, at any time and from time to time, may review, reconsider and change their position and/or change their purpose and/or develop such plans and may seek to influence management or the board of directors of the Issuer with respect to the business and affairs of the Issuer, and may from time to time consider pursuing or proposing any such transactions and, in connection therewith, may discuss, evaluate and/or pursue any such transactions with advisors, the Issuer or other persons.

The information in Item 6 of this Schedule 13D is incorporated herein by reference.

Item 5. Interest in Securities of the Issuer.

(a) – (b) The following disclosure assumes that there were 24,205,573 shares of Common Stock of the Issuer outstanding as of November 9, 2012 which number is based on information set forth in the Issuer’s Form 10-Q, filed with the Securities and Exchange Commission on November 14, 2012, plus the 5,000,000 shares of Common Stock purchased by Blackstone Holdings III as described in Item 6 of this Schedule 13D.

As of the date hereof, Blackstone Holdings III directly holds 5,000,000 shares of Common Stock.

Blackstone Holdings III GP L.P. is the general partner of Blackstone Holdings III. Blackstone Holdings III GP Management L.L.C. is the general partner of Blackstone Holdings III GP L.P. The Blackstone Group L.P. is the managing member of Blackstone Holdings III GP Management L.L.C. Blackstone Group Management L.L.C. is the general partner of The Blackstone Group L.P. Blackstone Group Management L.L.C. is wholly owned by its senior managing directors and controlled by its founder, Stephen A. Schwarzman. Each of the Blackstone Entities and Mr. Schwarzman may be deemed to beneficially own the shares of Common Stock beneficially owned by Blackstone Holdings III.

10

The aggregate number and percentage of the shares of Common Stock beneficially owned by each Reporting Person and, for each Reporting Person, the number of shares as to which there is sole power to vote or to direct the vote, shared power to vote or to direct the vote, sole power to dispose or to direct the disposition, or shared power to dispose or to direct the disposition are set forth on rows 7 through 11 and row 13 of the cover pages of this Schedule 13D and are incorporated herein by reference.

Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that any of the Reporting Persons (other than Blackstone Holdings III, which directly holds the shares of Common Stock reported on this Schedule 13D) is the beneficial owner of the Common Stock referred to herein for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended, or for any other purpose, and such beneficial ownership is expressly disclaimed.

(c) Except as set forth herein, none of the Reporting Persons has engaged in any transaction during the past 60 days in any shares of Common Stock.

(d) Not applicable.

(e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

Except as set forth in this Item 6 of this Schedule 13D, none of the Reporting Persons has any contract, arrangement, understanding or relationship (legal or otherwise) with any person with respect to any securities of the Issuer, including but not limited to, any contract, arrangement, understanding or relationship concerning the transfer or voting of any securities of the Issuer, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guaranties of profits, division of profits or loss or the giving or withholding of proxies.

On December 19, 2012 (the “Closing Date”), pursuant to the previously announced purchase and sale agreement, dated September 27, 2012 (the “Purchase Agreement”), by and between the Issuer and Huskies Acquisition LLC (the “Purchaser”), an affiliate of The Blackstone Group L.P., and the Assignment Agreement, dated as of the Closing Date (the “Assignment Agreement”), by and among the Issuer, the Purchaser and Blackstone Holdings III, the Issuer completed (i) the disposition of its investment management and special servicing business, including CT Investment Management Co., LLC (“CTIMCO”) and related private investment fund co-investments for a purchase price of $21,424,028 to the Purchaser and Blackstone Holdings III, and (ii) the sale to Blackstone Holdings III of the 5,000,000 shares of Common Stock for a purchase price of $10,000,000.

As part of a program designed by the Issuer to provide incentive compensation relating to carried interest distributions the Issuer earns from its investment funds, CT Opportunity Partners I, LP (“CTOPI”) and CT Legacy REIT Mezz Borrower, Inc. (“CT Legacy REIT”), the Issuer had created an award arrangement pursuant to which the Issuer’s compensation committee has previously awarded, and may in the future award, long-term cash-based performance awards that represent derivative

11

interests in such carried interest distributions. In connection with the purchase by Purchaser of the Issuer’s investment management business pursuant to the Purchase Agreement, management of CTOPI was transferred to affiliates of Purchaser at Closing; however, under the terms of the Purchase Agreement, the Issuer retained the rights to the aforementioned carried interest distributions following Closing, subject to the right of Purchaser to instruct the Issuer to award certain persons as directed by Purchaser, including employees of the Blackstone Entities or affiliated entities, performance awards in respect of the unallocated and/or forfeited portions of the award pool (which unallocated portions represented at the Closing approximately 7.5% of the 45% of the CTOPI carried interest and 16.5% of the 6.75% of the CT Legacy REIT recovery pool, respectively, allocated to the award pool).

Pursuant to the terms of the Purchase Agreement, on the Closing Date, the Issuer entered into the Management Agreement with an affiliate of the Blackstone Entities, as described in Item 4 of this Schedule 13D, and a registration rights agreement with Blackstone Holdings III (the “Registration Rights Agreement”). Pursuant to the Registration Rights Agreement, on and after December 19, 2013, Blackstone Holdings III may require the Issuer to prepare and file a shelf registration statement relating to the resale by Blackstone Holdings III of the shares of Common Stock purchased as described in this Item 6 and under certain circumstances may require the Issuer to file up to four resale registration statements on demand and provide “piggyback” registration rights with respect to resale of such shares of Common Stock.

The descriptions of the Purchase Agreement and related Assignment Agreement, the Management Agreement and the Registration Rights Agreement contained in Item 4 and this Item 6 are not intended to be complete and are qualified in their entirety by reference to such agreements, each of which is filed as an exhibit hereto and incorporated by reference herein.
