In anticipation of their proposed merger receiving final approval, insurance brokers Aon and Willis Towers Watson announced the future leadership team for the firm that will be effective following the close of the merger, which they expect to occur before the end of the second quarter.

The new organization, which will be named Aon, will be guided by what the executives are calling “a one firm” mindset.

“This talented team draws on the best of both from each organization and will be critical to delivering on the high aspirations we have for the new Aon,” said Greg Case, Aon CEO.

“As we learned more about each other’s organizations, it became clear that a fundamental driver of our success will be leaders who fully embrace a one firm mindset,” said John Haley, CEO, Willis Towers Watson. “The willingness to put the needs of clients and the entire organization ahead of their part of the business and any individual priorities will be the key to unlocking the full potential of the planned combination for the benefit of all our stakeholders.”

Shareholders of both firms approved the merger in August.

The European Commission (EC) is currently conducting an antitrust review of Aon’s proposed $30 billion bid for Willis Towers Watson. Aon has said the review is a common next step for a transaction of this size and complexity.

A full-scale EC investigation will take until May 10, 2021, according to the EC.

Aon has said it remains on track to close the deal in the first half of 2021.

Following completion of the proposed merger, Case, as CEO, and Christa Davies, as chief financial officer, will be joined by the following executives in forming the new Aon Executive Committee:

Eric Anderson, president; Maggie Westdale, CFO, Business; and Julie Gebauer, head of Strategy.

Reporting to Anderson will be Alexis Faber, CEO, North America; Julie Gebauer, CEO, Health, Wealth and Career; Carlo Clavarino, chair, International; Eduardo Davila, CEO, EMEA; Lambros Lambrou, CEO, Commercial Risk; Adam Garrad, president, Commercial Risk and CEO Global Broking; Lori Goltermann, chief client officer; Julie Page, CEO, United Kingdom; Andy Marcell, CEO, Reinsurance; James Kent, deputy CEO, Reinsurance; Luis Maurette, CEO, Latin America; Alejandro Galizia, president, Latin America; and Anne Corona, CEO, Asia-Pacific.

Also Anne Pullum, chief innovation officer; Andy Weitz, chief marketing officer; Pam Rollins, internal communications; and Darren Zeidel, general counsel.

Also Lisa Stevens, chief People officer; James Platt, chief operating officer; and Katherine Gehman, chief of staff.
