MURRAY FRANK LLP Investigates Breaches Of Fiduciary Duty Regarding Merger Of Allied World Assurance With Transatlantic Holdings (TRH)

NEW YORK, NY (BUSINESSWIRE) - MURRAY FRANK LLP is investigating claims of breach of fiduciary duty by certain members of the board of directors of Transatlantic Holdings, Inc. Co. (NYSE: TRH) ("Transatlantic" or the "Company") in relation to the merger of the Company with Allied World Assurance Company (NYSE: AWH) ("AWA").

On June 13, 2011, Transatlantic and AWH announced that the two companies would merge pursuant to a transaction under which Transatlantic stockholders will receive 0.88 AWH common shares for each share of Transatlantic common stock, or approximately $51.10 per share. The amount represents a premium of only 16% over the closing price of the stock on June 10, 2011.

The investigation concerns whether certain members of the board of directors breached their fiduciary duty in connection with their efforts to merge Transatlantic with AWH for an inadequate price through an unfair process which significantly undervalues the Company.

If you are a current investor in Transatlantic, who purchased TRH shares before June 13, 2011, and you wish to discuss this investigation or have any questions concerning this notice or your rights or interests with respect to these matters, please contact Gregory Frank at (800) 497-8076 or (212) 682-1818, or by email at [email protected].
