Washington State Investment Board (WSIB) plans to invest $1.25bn (€1.1bn) in real estate operating companies through three of its existing partners.

The $142bn pension fund confirmed to IPE Real Assets that it has approved two $500m commitments to Aevitas Property Partners and Partners Enterprise Capital, and a $250m commitment to Calzada Capital Partners.

All three companies specialise in investing in real estate operating companies.

Aevitas invests in European companies and WSIB has been investing with the Amsterdam-based platform since it was established in 2012.

Partners Enterprises Capital invests in US companies and last year became independent from Principal Global Investors.

Calzada has investments in companies across the Americas and Australia.

WSIB is also investing $250m in digital infrastructure through GI Partners.

The pension fund is committing $175m to the GI Data Infrastructure Fund and a further $75m of co-investment capital.

GI Partners is seeking to raise $1.25bn for the fund.
