Insurance broker Aon announced the promotions of Alfonso Valera as CEO of International for Reinsurance, responsible for UK, EMEA and APAC, and Steve Hofmann as CEO of Americas for Reinsurance, responsible for North America and Latin America. In addition, George Attard has been named global head of Strategy and Tomas Novotny has been appointed chairman of International.

Aon said these reinsurance appointments are unconnected to today’s announcement from AIG that John Neal, the former CEO of Lloyd’s, would be taking up a major executive role at the insurer, rather than moving to Aon as CEO of Reinsurance as originally had been planned.

At the start of 2025, Neal had been named CEO of reinsurance at Aon, and has been on gardening leave since he left Lloyd’s at the end of May – but he never actually worked for Aon. Today, AIG announced he will take a different direction, leading AIG’s General Insurance—North America and international commercial insurance businesses plus AIG’s global personal insurance book.

An Aon spokesman noted that these regional appointments had been in train before AIG’s announcement about Neal, and the broker decided to move up its announcement when Neal made his decision to move to AIG — in order “to provide clarity” about the team.

“AIG is a great partner of ours, and we really support what’s happening here,” the Aon spokesman said. He explained there are no plans to conduct a search for a CEO of reinsurance because Andy Marcell will remain in his current role with the new team reporting into him. Marcell leads Aon’s integrated Risk Capital and Human Capital capabilities across the firm’s Reinsurance, Commercial Risk, Health, Wealth and Talent teams.

“We wish John Neal great success in his new role and look forward to working with him at AIG. Global Solutions CEO Andy Marcell and our industry-leading Reinsurance team are strongly positioned to continue to innovate on behalf of our clients,” said Aon in an official statement.

Valera previously served as co-CEO of EMEA for Reinsurance and, before that, as CEO and general manager of Aon Re Iberia, among other leadership roles. Hofmann previously served as U.S. CEO of Reinsurance and earlier as U.S. co-president of Reinsurance.

Attard most recently served as CEO of Reinsurance for APAC, following 17 years at the firm leading strategy and client engagement in the region. Novotny has served as co-CEO of EMEA for Reinsurance, chairman of the board of Central and Eastern Europe for the firm and as a broking leader for Aon based in Prague.
