Ohio Public Employees Retirement System could become under-allocated to real estate as it acknowledges the difficulty of investing in the asset class today without taking undue levels of risk.

In a board meeting report, the $83.7bn (€68.7bn) pension fund said: “The challenge for staff is to find new opportunities that have desirable expected returns at acceptable levels of expected risk�.

Its investment consultant Aon also stated in the report that “redeploying capital is more challenging at current point in the cycle� without adding more risk and that this might “cause allocation to fall below target�.

Ohio PERS’s most recent figures show that its private real estate allocation fell from 9.42% at the end of June last year to 9.16% at the end of Septmber, below its 10% target.

The pension fund had planned to make more than $1bn of direct real estate acquisitions and invest $500m in closed-ended real estate funds in 2017. But figures for the first three quarters of the year show that it only bought $341m of direct property and failed to make any fund commitments. It did manage to redeem $150m from core open-ended real estate funds.

Ohio PERS was actually a net seller during the nine-month period, disposing of $361m of real estate held in separate accounts.

The pension fund said that, since 2015, it had “sold assets at high prices and realised gains�, capitalising on “excess demand for stablised, core properties�.

Ohio PERS had expected a correction in the US real estate market in 2017, but it now believes the market will continue to plateau, according to the report. “However, staff does not see a near-term catalyst that would cause property values to decline,� it said.

For future investments, the pension fund is focusing on debt and preferred equity, select development opportunities, and secondary-market transactions.

“Staff believes these strategies will enable the portfolio to achieve its performance objective and also provide a degree of downside protection during a market correction,� it said.
