(“Merger Sub I”) and Dakota Acquisition II, LLC (“Merger Sub II”) (~~the ~~“Merger Agreement”). Under the~~ terms of the ~~Merger~~previously ~~Agreement,~~announced ~~(i)~~merger ~~Merger~~agreement, ~~Sub~~dated Ias ~~will~~of beDecember ~~merged~~30, ~~with~~2012, ~~and~~between ~~into~~ the Company, ~~with~~Duff ~~the~~& ~~Company~~Phelps ~~continuing~~Acquisitions, asLLC, the ~~surviving~~Company's ~~corporation in the merger and a~~ wholly- owned subsidiary ~~of Parent (the “Company Merger”)~~, and ~~(ii) Merger Sub II will be merged with and into DPA, with DPA as the surviving entity in the merger and~~ a ~~wholly-owned~~consortium ~~subsidiary of the Company~~ (the “~~DPA Merger~~Consortium” ~~and, together with the Company Merger, the “Mergers”~~)~~. The~~ ~~DPA~~comprising ~~Merger~~controlled ~~will~~affiliates ~~take~~of ~~effect immediately before the Company Merger. Parent is affiliated with entities~~ or funds managed by The Carlyle Group, Stone Point Capital LLC, Pictet & Cie and The Edmond de Rothschild Group.

At the effective time of the DPA Merger, each outstanding New Class A Unit of DPA (other than units owned by the Company, Parent or their respective subsidiaries, or by any unitholders who are entitled to and who properly exercise appraisal rights under the Merger Agreement) will be cancelled and converted into the right to receive $15.55 per New Class A Unit in cash (the “Per Unit Merger Consideration”), plus any unpaid distributions declared in accordance with the Merger Agreement in respect of such New Class A Unit with a record date prior to the effective time of the DPA Merger, in each case, without interest, and each outstanding share of the Company's Class B common stock will be cancelled without any consideration therefor. At the effective time of the Company Merger, each outstanding share of the Company's Class A common stock (other than shares owned by the Company, Parent or their respective subsidiaries, or by any shareholders who are entitled to and who properly exercise appraisal rights under Delaware law) will be cancelled and converted into the right to receive $15.55 per share of Class A common stock in cash (the “Per Share Merger Consideration”), plus any unpaid dividends declared in accordance with the Merger Agreement in respect of such share of Class A common stock with a record date prior to the effective time of the Company Merger, in each case, without interest. In lieu of receiving the Per Share Merger Consideration, Parent and certain officers of the Company have agreed that such officers will contribute a portion of their shares of Class A common stock immediately prior to the effective time of the Mergers in exchange for equity securities of Parent.

As a result of the Company Merger, unless otherwise agreed with the holder thereof, each option to purchase the Company's Class A common stock outstanding immediately prior the Company Merger, whether vested or unvested, will be cancelled in exchange for the right to receive the excess of the Per Share Merger Consideration over the exercise price of such option, less applicable taxes required to be withheld. Pursuant to the Merger Agreement, at the effective time of the Company Merger, each restricted stock award, restricted stock unit award and any other similar equity award outstanding immediately prior to the effective time of the Company Merger which is held by a non-employee member of the Board of Directors of the Company (each, a “Director RSA”) will be cancelled in exchange for the right to receive a lump sum cash payment of the Per Share Merger Consideration, without interest. Unless otherwise agreed with the holder thereof, at the effective time of the Company Merger, each restricted stock award, restricted stock unit award and any other similar equity award outstanding immediately prior to the effective time of the Company Merger that is not a Director RSA will be assumed and converted into the right to receive the Per Share Merger Consideration, with the right to receive such amount subject to the satisfaction of any vesting conditions applicable under the applicable award agreement.

The Board of Directors of the Company has approved, and declared to be advisable, the Merger Agreement and the transactions contemplated thereby, including the Mergers.

Under the terms of the Merger Agreement, the Company and its advisors are permitted to actively solicit and consider alternative proposals from third parties until 11:59 p.m., Eastern Time, on February 8, 2013 (the “Go-Shop Period”). In addition, the Company would be permitted to, among other things, engage, enter into and participate in discussions and negotiations with certain parties who during the Go-Shop Period have made a proposal that the Board determines would reasonably be expected to result in a superior proposal (“Excluded Parties”) until March 8, 2013. If the Merger Agreement is terminated to enter into a superior proposal with an Excluded Party prior to March 8, 2013, the Company will be required to pay to Parent a termination fee of approximately $6.65 million plus expense reimbursement of up to $1.25 million. The Company does not intend to disclose any developments with respect to this process unless and until its Board of Directors makes a decision regarding a potential superior proposal. There can be no assurances that this process will result in any superior proposal or alternative transaction.

The Merger Agreement contains representations, warranties and covenants of the parties customary for a transaction of this type. The Merger Agreement may be terminated under certain circumstances, including in specified circumstances in connection with superior proposals. Upon the termination of the Merger Agreement, under specified circumstances, the Company will be required to pay Parent a termination fee, the amount of which would depend on the circumstances under which the Merger Agreement is terminated. Under specified circumstances under which the Merger Agreement is terminated, Parent will be required to pay the Company a termination fee.

Assuming the satisfaction of conditions, the Company expects the transactions contemplated by the Merger Agreement to close in the first half of 2013. Consummation of the Mergers is not subject to a financing condition, but is subject to customary closing conditions, including (i) the affirmative vote of a majority of the votes entitled to be cast by holders of Class A common stock and Class B common stock, voting together as a single class, (ii) the expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, (iii) the approval by the UK Financial Services Authority; (iv) the approval by the Financial Industry Regulatory Authority (or the expiration of a certain agreed upon waiting period during which the Financial Industry Regulatory Authority has not indicated that it intends to impose certain material restrictions on the parties); and (v) other customary conditions.

The foregoing summary of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement, a copy of which is attached as Exhibit 2.1 to this report and is incorporated herein by reference. The Merger Agreement has been included to provide investors with information regarding its terms. It is not intended to provide any other factual information about the Company, Parent, Merger Sub I, Merger Sub II or their affiliates. The representations, warranties and covenants contained in the Merger Agreement were made only for the purposes of that agreement and as of the specific dates, were solely for the benefit of the parties to the Merger Agreement, and may be subject to limitations agreed upon by the parties, including being qualified by information in confidential disclosure schedules that the parties have exchanged in connection with signing the Merger Agreement and made for the purposes of allocating contractual risk among the parties to the Merger Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors are not third-party beneficiaries of the Merger Agreement and should not rely on the representations, warranties or covenants or any description thereof as characterizations of the actual state of facts at the time they were made or otherwise. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Company's public disclosures.

The information set forth under Item 1.01 of this Current Report on Form 8-K is incorporated into this Item 5.02 by reference.
