Hawaii’s largest public pension fund performed slightly better in fiscal year 2017 than it reported two months ago in its preliminary numbers.

Chief Investment Officer Vijoy Chattergy said Wednesday that final fiscal year results showed investments in the Employees’ Retirement System portfolio increased 13.7 percent for the 12 months ended June 30. The ERS said in August that its portfolio had risen 13.4 percent. The value of the assets remained at a record $15.6 billion.

It was the best return since the portfolio gained 17.4 percent three years ago and easily surpassed the ERS trustees’ investment target of 7.55 percent.

As of June 30 the pension fund was up an annualized 5.5 percent for a three-year period, up 9.3 percent for five years and ahead 5.3 percent for 10 years.

The ERS portfolio provides retirement, disability and survivor benefits to more than 120,000 active, retired and inactive state and county employees.

Chattergy said the recent percentage change reflects final valuations coming in for private market strategies such as private equity and real estate, which always reports with a lag.

Independent Dallas-based actuary Gabriel Roeder Smith &Co. will release in December how much of a shortfall the pension fund had as of June 30 of this year. The fund had a $12 billion shortfall and was only 54.7 percent funded as of June 30, 2016.

Portland, Ore.-based Pension Consulting Alliance LLC, which advises ERS trustees on investments, is due to report results for the first quarter of fiscal 2018 on Nov. 13.

Separately, the ERS board of trustees is being recognized as a finalist for board of the year by Institutional Investor magazine.
