July 30 (Reuters) - AXA IM Prime, a unit of AXA

Investment Managers, will acquire a 20% stake in French private

credit firm Rivage Investment, the two companies said in a joint

statement on Tuesday.

Separately, AXA IM Prime, a long-standing investor in

Rivage's strategies, will also put money in some of its

infrastructure debt strategies, the companies said.

Rivage has over 7.7 billion euros ($8.33 billion) in

committed capital under management.

Bloomberg, which first reported the news, said AXA IM Prime

was looking to raise about 400 million euros for its first

General Partner stakes fund and has already raised at least half

of that target.

AXA IM aims to accelerate Rivage's growth with new

initiatives and international expansion, the companies added.

Rivage has invested more than 8.2 billion euros on behalf of

blue-chip institutional investors since the launch of its first

fund in 2013.
