Towers Watson & Co. (NASDAQ:TW), a global professional services company, today urged stockholders to support the merger of equals with Willis Group Holdings (NYSE:WSH) (“Willis”) and vote “FOR” the creation of Towers Watson/Willis at the December 11, 2015 Special Meeting of Stockholders.

On November 19, 2015, Towers Watson announced an amended merger agreement with Willis. Under the terms of the amended agreement, which was unanimously approved by the Towers Watson Board of Directors, the one-time cash dividend to be paid to Towers Watson stockholders was increased to $10.00 per Towers Watson share, which was the result of a significant negotiation between Towers Watson and Willis. Adjusted for the special dividend, Towers Watson stockholders will receive 52% of the total transaction value.

John Haley, Chairman and Chief Executive Officer of Towers Watson, said, “We continue to believe that the combination of Willis and Towers Watson is a compelling opportunity to enhance the competitive position of both companies and generate significant stockholder value. We have had constructive discussions with our stockholders since the terms were revised to more than double the special dividend and have been encouraged by their feedback. The terms of the revised agreement with Willis represent the best and final offer for Towers Watson stockholders. We are confident this transaction is the best way to maximize value for our stockholders today and over the long term, and encourage all stockholders to vote for the creation of Willis Towers Watson at the December 11, 2015 Special Meeting.”

Following the merger, Towers Watson stockholders will have an approximately 49.9% ownership interest in a leading integrated global advisory, broking and solutions firm that is expected to deliver approximately $4.7 billion in total incremental value to stockholders through a combination of cost savings, revenue synergies and tax efficiencies, driving anticipated cash earnings accretion of approximately 42% by 2018.

As previously announced, the Towers Watson Special Meeting of Stockholders will be held on December 11, 2015. Towers Watson stockholders of record as of the close of business on October 1, 2015 will be entitled to vote at the Towers Watson Special Meeting.

Stockholders who have already voted do not need to recast their votes. Proxies previously submitted will be voted at the reconvened meeting unless properly revoked. Stockholders who have not already voted or wish to change their vote are encouraged to do so using the instructions provided in their voting instruction form or proxy card.

The Towers Watson Board remains confident the Towers Watson/Willis merger is in the best interest of Towers Watson’s stockholders and unanimously recommends that stockholders vote “FOR” the approval and adoption of the amended Merger Agreement and related proposals at the December 11, 2015 Special Meeting.
