California State Teachers’ Retirement System (CalSTRS) has gained a controlling stake in a US residential platform from .

The $229bn pension fund said it has acquired a majority interest in Fairfield Residential Company for an undisclosed sum.

Fairfield was majority-owned by Brookfield and minority-owned by CalSTRS. 

CalSTRS said following the latest transaction,  retained its interest in the investment manager of Fairfield’s affiliated real estate funds.

Recently CalSTRS adopted what it called a “Collaborative Model� for investments across all asset classes in its portfolio.

The CalSTRS Collaborative Model creates long-term relationships between CalSTRS and other long-term investors to create efficient investment vehicles that produce attractive sources of return by effectively using the strengths of each investor.

CalSTRS said this transaction [Fairfield] was possible because of the flexibility built into CalSTRS Collaborative Model.

CalSTRS director of real estate Mike DiRé, said: “The result is our ability to align the real estate portfolio with a top-tier manager and long-time CalSTRS real estate partner.

“Transitioning to majority owner was appealing for a number of reasons, including the expansion of Fairfield’s geographic footprint and the growth of its capital base to include other like-minded investors.�

CalSTRS has been a partner of Fairfield’s since 1997 and a minority owner since 2005. Currently, the pension fund has over $2bn committed with the company in develop-to-core, value-add, and affordable housing strategies.

Associate portfolio manager Josh Kawaii-Bogue, said: “As a majority owner, CalSTRS will be able to create better investment cost efficiencies and enhance its investment execution efforts in the coming years.�

Deputy CIO Officer Scott Chan, said: “CalSTRS will continue to partner with best in class managers and operators as it seeks to create better alignment and reduce costs across its real estate portfolio.�

Fairfield CEO Greg Pinkalla, said: “Fairfield looks forward to building on our 20-year relationship with CalSTRS as we continue to originate and execute varied investment strategies in the multifamily space.�
