Summary
The New Hampshire Retirement System, Concord, is continuing a restructuring of its U.S. equity portfolio, shifting approximately $1 billion from BlackRock-managed assets to Acadian Asset Management, according to Pensions & Investments. The move is part of a broader effort by the system to improve performance and reduce tracking error relative to its benchmark.

The BlackRock S&P 500 strategy holds approximately $3.24 billion in assets, and NHRS will retain most of that allocation following the transfer. The reallocation reflects a targeted trim of the BlackRock position rather than a full exit from the manager.

NHRS is a public employee defined benefit plan providing retirement, disability, and death benefits to eligible members and beneficiaries. The system had $11.6 billion in total assets under management as of June 30, 2023, per its own disclosures. It reported a 10.3% return on investments for the fiscal year ended June 30, 2025, with three-year, five-year, 10-year, and 25-year returns also published in its investment reporting.

The Acadian mandate was approved as a separate account, and the system's dashboard notes that NHRS exceeded $1 billion in pension benefit payments for the second consecutive year in fiscal 2026, with close to 80 percent of members in a defined benefit structure.
