Teacher Retirement System (TRS) of Texas has readied $400m (€361m) of capital to co-invest alongside the latest infrastructure mega-funds of Brookfield Asset Management and Global Infrastructure Partners (GIP).

The pension fund confirmed to IPE Real Assets that it plans to co-invest $300m alongside Brookfield Infrastructure Fund IV and $100m alongside Global Infrastructure Partners IV.

TRS Texas is effectively doubling its exposure, having already committed the same amounts, respectively, to the two vehicles.

Brookfield and GIP are each seeking to raise $20bn for their funds, according to Preqin.

To co-invest alongside the GIP fund, TRS Texas has committed the $100m of capital to a specialist entity Infra Investors II.
