Hans Stoter was named global head of AXA IM Core, a newly created unit within AXA Investment Managers.
The unit brings together AXA IM's €536 billion ($600 billion) equities, fixed-income and multiasset strategies.
Mr. Stoter is currently global head of core investments. Details on any replacement were not immediately available.
Paul Flavier, currently chief risk officer of AXA IM, was named head of Rosenberg Equities, effective March 31. He will replace Heidi Ridley who is to pursue diversity and environmental, social and governance opportunities outside of the firm. Rosenberg Equities is part of AXA IM's equity business and runs quantitative strategies. Assets under management could not immediately be learned.
The firm's alternatives businesses will be combined into a new separate unit, AXA IM Alts, which will have €137 billion in assets.
Isabelle Scemama, CEO of AXA IM-real assets, will lead the alternatives unit, which is composed of €87 billion in real assets, €48 billion in structured finance assets and the firm's €2 billion hedge fund business, Chorus, a spokeswoman said. The move will simplify access to the firm's strategies for its clients, but each of the three businesses will retain autonomy under the AXA IM Alts umbrella, she added.
In addition, Deborah Shire was named deputy head of AXA IM Alts. The role is new and Ms. Shire will focus on corporate development. She will also retain her role as global head of structured finance and will join AXA IM's management board.
Florence Dard, global head of business development at AXA IM-real assets, will also take on the role of global head of client group, alts.
The changes are expected to take effect in the second quarter.
"We strongly believe in leveraging both traditional and alternative asset classes to further provide investors with adequate responses to the current hunt for yield and to bring them long-term value," Gerald Harlin, executive chairman of AXA IM, said in a news release. "We want our organization to reflect this belief and that is why we aim to implement a simplified structure comprised of two key strategic business units."
