Michigan Public School Employees Retirement System (MPSERS)
public plan · State of Michigan · Lansing, MI
Michigan Public School Employees Retirement System (MPSERS) is underfunded: 60% funding ratio, with $35.4B in unfunded actuarial liability against $54.0B in plan assets. Plans below 75% funded face heightened regulatory scrutiny and usually require higher sponsor contributions or benefit adjustments to recover.
Michigan Public School Employees Retirement System (MPSERS) is a public-sector pension plan sponsored by State of Michigan — covering government employees (state, local, or special-district workers). Public plans are not ERISA-governed and not PBGC-insured; they rely on state-level oversight and tax-base solvency. The plan remains active — accruing new benefits for current employees and accepting new participants. Among private-sector single-employer plans, the active status is increasingly rare as employers freeze accruals while continuing to fund existing obligations; public-sector plans are more often still actively accruing.
On scale, Michigan Public School Employees Retirement System (MPSERS) is a mega-plan: $54.0B in assets serving 465,000 participants (225,000 active, 240,000 retired). Plans this large dominate the U.S. pension landscape and carry concentrated solvency risk. The participant mix runs roughly even between 225,000 active workers and 240,000 retirees — a balanced demographic profile that gives the plan time to compound investment returns before payouts dominate cash flow. Annual cash flows: $5.5B in sponsor contributions versus $5.8B in benefit payments. Investment performance over the most recent year ran 5.3%, against the plan's assumed long-term return of 6.0%.
PBGC risk classification: high. The plan is on enhanced monitoring and may face funding-improvement or rehabilitation-plan requirements depending on multi-year trajectory. Public plans like Michigan Public School Employees Retirement System (MPSERS) are not PBGC-insured. The benefit guarantee rests on the sponsoring government's ability and willingness to make required contributions, which interacts with state and local tax-base dynamics.
