It’s the first time the $180.7 billion fund has formed such a partnership, Comptroller Thomas DiNapoli, the pension’s sole trustee, said today in a statement. In addition to investing the funds with equity managers, the unit of Goldman Sachs Group Inc. will also provide advice across the pension’s remaining $98 billion equity portfolio.

“Identifying new opportunities is key to the continued growth of the fund’s long-term value,” DiNapoli said. It will give the pension “full access to world-class global equity investment opportunities and the nimbleness to take advantage of them on a timely basis.”

New York joins public pension funds including New Jersey, New York City and the Teacher Retirement System of Texas in making big allocations of capital to investment managers that can be deployed more quickly and across different strategies. Such separately managed accounts offer cheaper fees and more control for investors, who in turn agree to commit large sums for a decade or more.
