## About

The Massachusetts Bay Transportation Authority Retirement Fund was established in 1948 as a private trust. It provides retirement benefits to employees of the MBTA and related transit workers. The fund operates under directives from its board and maintains relationships with the Boston Carmen's Union Local 589. The fund allocates across real estate and private equity.

It also maintains commitments to Lexington Capital Partners IX, New Mountain Partners VI, and HarbourVest Partners 2022. Geographic exposure centers on the United States with additional positions in Europe and global secondaries. The fund reported 1,824 million USD in assets according to internal records. It maintains service relationships with KPMG as auditor, State Street Bank & Trust Company as custodian, and Segal Marco Advisors as investment advisor. A board meeting occurred in December 2025 covering investment performance and financial reporting. The fund operates under a statutory mandate to transfer 50 percent of portfolio assets to the Pension Reserves Investment Trust managed by the PRIM Board.
