NEW YORK -- December 30, 2012

Duff & Phelps Corporation (NYSE: DUF) (“the Company”), a leading independent
financial advisory and investment banking firm, announced today that it has
entered into a definitive merger agreement under which a consortium (“the
Consortium”) comprising controlled affiliates of or funds managed by The
Carlyle Group, Stone Point Capital LLC, Pictet & Cie and Edmond de Rothschild
Group will acquire the Company for $15.55 per share in cash in a transaction
valued at approximately $665.5 million.

The offer represents a 19.2% premium to the closing price of Duff & Phelps
shares on December 28, 2012, and 27.3% over the Company’s volume weighted
average share price during the 30 days ended December 28, 2012. The
transaction is expected to close in the first half of 2013, subject to
customary closing conditions—including the receipt of stockholder and
regulatory approvals.

Noah Gottdiener, chief executive officer of Duff & Phelps, said, “Duff &
Phelps Board of Directors, acting on advice from the Company’s legal and
financial advisors, agrees that this transaction is in the best interest of
our stockholders, who will receive an immediate and certain cash premium for
their shares. Importantly, the transaction will be structured to preserve the
firm’s independence as we serve our clients in the future.”

Olivier Sarkozy, Managing Director and head of Carlyle’s Global Financial
Services group, said, “Regulatory demands, implementation of new accounting
policies and requirements for increased corporate disclosure and third party
validation provide significant growth opportunities for Duff & Phelps core
products and services. We will harness Carlyle’s and Stone Point’s global
networks while leveraging Duff & Phelps preeminent brand to foster growth in
new geographies. Additionally, we believe the involvement of Pictet and Edmond
de Rothschild Group will support the Company’s initiatives to enhance its
international presence and expand its Limited Partner client base. We are
excited to work with Noah and his management team on this opportunity.”

Charles A. Davis, Chief Executive Officer of Stone Point Capital, added, “Noah
and his colleagues have performed admirably throughout market cycles and have
done a superb job executing their business plan to grow the Company. Today,
Duff & Phelps is well-positioned in the marketplace, and we believe that
demand for the Company’s independence, integrity and professionalism will only
increase in the current environment.”

The merger agreement provides for a “go-shop” period commencing immediately
and ending on February 8, 2013, during which the Company, with the assistance
of its financial and legal advisors, will actively solicit and potentially
receive, evaluate and enter into negotiations with third parties that offer
alternative transaction proposals. It is not anticipated that any developments
will be disclosed with regard to this process, unless the Duff & Phelps board
makes a decision with respect to a potential superior proposal. There is no
guarantee that this process will result in a superior proposal. The merger
agreement provides for a break-up fee of approximately $6.65 million if the
Company terminates the agreement prior to March 8, 2013, in connection with a
superior proposal that first arose during the go-shop period.

All members of the senior management team have agreed to remain employed by,
and invest in the equity of, the Company following the closing of the
transaction. They have agreed to offer to participate on similar terms in any
other acquisition proposal that may be made for the Company.

The pro forma Board of Directors will comprise nine members – including two
representatives each from the management team, The Carlyle Group and Stone
Point Capital, in addition to three independent directors. No single member of
the Consortium will own more than 35% of the pro forma Company.

The transaction has been approved by the Board of Directors of Duff & Phelps,
following the recommendation of a transaction committee consisting of
independent directors. The Board of Directors of Duff & Phelps recommends that
stockholders vote in favor of the transaction at the special meeting of
stockholders that will be called to approve the transaction. Stockholders
beneficially owning an aggregate of approximately 10% of the outstanding
shares of the Company have already agreed to vote their shares in favor of the
transaction; these commitments terminate if the merger agreement is
terminated.

The merger agreement provides that the Company can continue to pay dividends
if declared by the Company in the normal course prior to closing of the
merger.
