San Diego Transit Corporation Employees' Retirement Plan

San Diego Transit Corporation Employees' Retirement Plan

The San Diego Transit Corporation Employees' Retirement Plan is a single-employer defined-benefit plan established for workers of the San Diego Transit Corporation, a subsidiary of the San Diego Metropolitan Transit System. The plan covers unionized employees represented by the International Brotherhood of Electrical Workers Local 465 and the Amalgamated Transit Union Local 1309, who operate the region's bus and trolley networks. MTS acts as the plan fiduciary, with administrative oversight from MTS executive leadership. The portfolio allocates across public equities, fixed income, and alternative asset classes through a combination of external managers and commingled funds. The plan's investment posture is shaped by actuarial funding requirements and liability-matching objectives rather than opportunistic mandates. Asset-class exposure typically includes domestic and international equity mandates, core and credit-oriented fixed income, and limited allocations to real assets and private markets when permitted by the investment policy statement. The geographic footprint concentrates on US-domiciled strategies, consistent with the domestic nature of the plan's liabilities and regulatory environment. Sharon Cooney serves as CEO of MTS, the parent agency that houses the fiduciary oversight function. Mike Thompson, MTS Director of Financial Planning and Analysis, is among the staff involved in financial operations touching the plan. MTS board meetings — held regularly in San Diego — serve as the governance forum where investment policy and actuarial assumptions are reviewed. The plan's size and funding status are not publicly disclosed with granularity, though periodic actuarial reports filed with state regulators capture benefit obligations and contribution schedules. Unlike multi-employer transit plans or state-level systems, this plan remains a closed, single-employer entity — no new bargaining units are added unless the San Diego Transit Corporation absorbs another operating division. That structure concentrates governance entirely within the MTS board, eliminating the joint-trusteeship dynamics common in Taft-Hartley plans. The absence of external participant inflows makes the plan's funded-status trajectory almost entirely a function of investment returns, employer contributions, and negotiated benefit tiers.
