New Mexico Educational Retirement Board (NMERB) has created a separate account with Stonepeak to invest in US infrastructure debt.

Mark Canavan, senior portfolio manager for New Mexico for real estate and real assets, said the pension fund had committed $25m (€23m) but added that this could be increased in the future β€œdepending on the performance of the initial allocation”.

It is rare for US public pension funds to create separate accounts for infrastructure debt, according to industry sources – most are focused on infrastructure equity.

Stonepeak has been the top performing infrastructure investment manager for NMERB. According to the pension fund’s website, the $50m commitment it made in 2015 to the Stonepeak Infrastructure Fund II produced a 42.5% net IRR by the end of 2016.

The next best performing manager was I Squared Capital. NMERB yielded a 19.9% net IRR for the $50m commitment it  to the ISQ Global Infrastructure Fund.

The separate account, called Stonepeak Credit, will target a net internal rate of return (IRR) of between 8% and 9%.

The deal size for the separate account will be in the range of $5m to $15m.

Stonepeak Credit will invest in a range of infrastructure assets, including those in the power, water, energy, communication, renewable energy and transportation sectors.
