Building for the future since 1948

The Massachusetts Bay Transportation Authority Retirement Fund is a private trust created in 1948 by the Metropolitan Transit Authority, the predecessor agency to the Massachusetts Bay Transportation Authority (“MBTA”) and The Boston Carmen’s Union, Amalgamated Transit Union Local 589. Our mission then, as now, is to provide retirement benefits for our members – the transit workers and other employees of the MBTA. To ensure that the pensions earned by active and retired members, and their beneficiaries, remain secure, we are dedicated to managing a strong and diversified investment program.
