## History

In 2016, London-based Willis Group merged with Arlington-based Towers Watson in a merger of equals and was renamed Willis Towers Watson. The merger was completed after a dividend payment to Towers Watson shareholders was increased after shareholders, including Driehaus Capital Management, opposed the initial proposal and the first shareholder vote for merger approval failed.

## Legal issues
### Inadequate compensation accepted by Towers Watson in merger with Willis Group; possible conflict of interest of Towers Watson CEO John Haley

In June 2015, in negotiating the acquisition of Towers Watson by Willis Group, Towers Watson first accepted an offer from Willis Group valued at $125.13 per share, or 9.3% lower than the trading price of Towers Watson stock at the time of the announcement. The deal also gave Willis Group shareholders more control of the combined company despite Willis having a lower market capitalization than Towers Watson. Towers Watson shareholder Driehaus Capital Management urged other shareholders to vote against the proposed merger, calculating that Towers Watson was worth between 39% and 53% more as a standalone company. Towers Watson CEO John Haley was accused of having a conflict of interest since he was to receive $165 million from the completion of the deal. Haley had disposed of 55% of his shares in the company for a $10 million profit in early March 2015 while the merger negotiations were ongoing and before the stock price dropped on the news of the acquisition.
In a shareholder vote on 18 November 2015, Towers Watson failed to get enough investor support for the proposed merger, with only 40% of shareholders voting in favor. Willis Group then increased the special cash dividend to be paid to Towers Watson shareholders to US$10 per share, increasing the total value of the offer to $130.26 per share, which was still lower than the trading price of Towers Watson shares at the time of the announcement. This revised offer was approved by Towers Watson shareholders on 11 December 2015.
A class action lawsuit was filed by shareholders led by the Regents of the University of California and represented by the law firm of Bernstein Litowitz Berger & Grossmann against Towers Watson, former Towers Watson CEO John Haley, former Willis CEO Dominic Casserley, and ValueAct Capital, which owned 10% of Willis Group and was led by Jeffrey W. Ubben who was a member of the board of directors of Willis and was involved in making the offer. The lawsuit was settled for $75 million plus $15 million to resolve a separate legal proceeding from the Delaware Court of Chancery. The defendants tried to collect $54 million from their directors and officers coverage, but were rejected by the courts as the policy had an exclusion for claims that would "bump-up" the price of an acquisition.
