Teachers Retirement System of the State of Illinois has approved new commitments for infrastructure and real estate totaling $500m (€358m).

The pension fund confirmed to IPE Real Assets that it had committed $300m to Oak Street Real Estate Capital Net Lease Property Fund and $200m to Carlyle Global Infrastructure Opportunity Fund.

Oak Street is seeking to raise $2.5bn capital raise for the Net Lease Property Fund, which will invest in net-leased office, industrial and retail assets across the US.

Oak Street already manages an existing portfolio valued at $44.1m on behalf of Illinois Teachers.

Illinois Teachers joined the Carlyle infrastructure fund during its final close last month, when it raised $2.2bn.

The commitment will significantly increase its real assets portfolio, which is valued at $520m and is separate to its $7.3bn real estate porfolio.
