RREEF Alternative Investments, Deutsche Bank's alternative asset management unit, has finalized an agreement to acquire a minority interest in Rosen Real Estate Securities, a long/short real estate investment adviser.

The firms will expand Rosen’s long/short investment platform and collaborate on product distribution, which will provide Deutsche Bank's institutional and high net-worth investors access to Rosen's strategies.

Rosen currently manages long/short real estate strategies, including its existing Rosen Real Estate Securities Value Fund I.

Earlier this year, Rosen announced that GIC Real Estate, the real estate arm of the Government of Singapore Investment Corp., had committed US$300 million and simultaneously acquired a minority stake in Rosen Real Estate Securities. GIC RE will remain an investor and owner.
