Under the terms of the tie-up, BPCE and Generali Investments will combine their asset management operations in a 50-50 joint venture, people familiar with the situation said. A non-binding preliminary agreement could be reached as early as next week. It would still need to be approved by the relevant unions and authorities.

Italy's top insurer Generali aims to reach a preliminary accord with Natixis Investment Managers to combine their asset management operations in order to submit the deal to its board on Jan. 20, two people close to the matter said.

Assicurazioni Generali SpA and Natixis SA are close to a deal for a joint venture in asset management to cut costs and team up on distribution, according to people familiar with the matter.
