Willis Towers Watson–Aon merger

George Rozanski and Bates White were retained on behalf of Willis Towers Watson (WTW) in its proposed $30 billion merger with Aon. A support team led by Slava Zayats and Zenon Zabinski assisted WTW at all stages of merger review ranging from preliminary antitrust risk assessment, Hart-Scott-Rodino-related submissions, and responses to the Department of Justice (DOJ)'s second request to multiple advocacy submissions and presentations to the DOJ. The Bates White team also collaborated with Bates White Affiliate Paul Johnson of Rideau Economics in assisting WTW with regulatory filings and advocacy submissions to the Canadian Competition Bureau. As part of their analysis, the Bates White team evaluated the competitive overlap and closeness of competition between Aon and WTW in numerous segments, including commercial risk broking, reinsurance broking, health benefits broking, private retiree exchanges, and actuarial services for defined benefit pension plans. The parties ultimately terminated the merger agreement.
