Massachusetts Pension Reserve Investment Management Board

What Massachusetts Pension Reserve Investment Management Board does

Massachusetts Pension Reserves Investment Management Board (MassPRIM) is a Massachusetts state government entity, established in 1980 under the statutory authority of Massachusetts General Laws Chapter 32, Section 23, that manages the assets of the Pension Reserves Investment Trust (PRIT) Fund on behalf of Massachusetts State Employees, Massachusetts Teachers', Boston Teachers', and local participating retirement systems throughout the Commonwealth. The PRIT Fund is a pooled, multi-asset-class investment vehicle with approximately $120 billion in assets under management, allocated across seven asset classes under a long-term strategic asset allocation framework: Global Equity (31-41% target range), Core Fixed Income (12-18%), Value-Added Fixed Income (6-12%), Private Equity (13-19%), Real Estate (7-13%), Timberland (1-7%), and Portfolio Completion Strategies (7-13%). As of June 30, 2025, the fund held Domestic Equity ($28.6B), International Equity ($12.1B), Emerging Markets ($4.8B), Core Fixed Income ($17.1B), Value-Added Fixed Income ($9.1B), Real Estate ($10.6B), Timberland ($3.2B), Private Equity ($19.2B), and Portfolio Completion Strategies ($10.0B), implemented primarily through external investment managers and consultants including BNY Mellon (custody), KPMG (audit), Meketa (public markets), NEPC (asset allocation), StepStone (private equity), IWC (timberland), and Aberdeen/New Alpha (portfolio completion strategies).

The fund serves 100 participating retirement systems covering more than 300,000 beneficiaries through two enrollment structures: full Participating Retirement Systems (mandatory five-year period) and Purchasing Retirement Systems (partial investment, no minimum), with a PRIT Fund Segmentation option for systems that prefer asset-class-level allocation. MassPRIM does not generate commercial revenue; it operates as a fiduciary for Massachusetts public pension beneficiaries, with total investment management costs of 52 basis points, an 8.8% annualized net return over the ten years ending December 31, 2025, and a 12.6% net gain in 2025. The Board is chaired by the Massachusetts Treasurer and Receiver General, Deborah B. Goldberg, and is supported by a Director of Stewardship (Veena Ramani) leading a formalized Stewardship Program adopted through Stewardship and Engagement Policies in 2024, with four approved priorities: Climate Transition Planning, Fair Pay, Sustainable Forestry, and Transparency. The organization is headquartered in Boston with 51-100 employees and has earned industry recognition including the GFOA Excellence Certificate for Financial Reporting (19th time, 2024) and a #1 ranking for its private equity portfolio by the American Investment Council.
