The City of Irving Supplemental Benefit Plan (SBP)

The City of Irving Supplemental Benefit Plan (SBP) provides an additional layer of retirement benefits for municipal employees who are already members of the Texas Municipal Retirement System (TMRS). The plan is sponsored by the City of Irving, Texas, and governed by a board chaired by Andrew Bah, with Ebony Roundtree serving as vice chair. Unlike the core TMRS benefit, the SBP is a separate fiduciary structure that accumulates assets to fund supplemental payouts — a design that gives the board discretion over a dedicated pool of capital. The plan's investment strategy is concentrated in buyouts, according to Altss research. No external investment consultant or outsourced chief investment officer is disclosed. Total assets and deployment are not publicly reported. The plan carries no dedicated investment staff beyond its board and municipal officers, making it heavily reliant on fund-manager selection and monitoring by the named finance and HR leads. Structurally, the SBP is distinct from most municipal supplemental plans, which often default to 457(b) or defined-contribution architectures with participant-directed investment menus. Irving instead maintains a board-governed trust with a single-strategy allocation, concentrating fiduciary risk and opportunity in the buyout decisions of a small group of city officials. That concentration makes the plan's governance quality — specifically the board's capacity to diligence and monitor illiquid commitments — the determining factor in its long-term performance.
