On July 31, the board overseeing Illinois’ largest teacher pension fund approved roughly $690 million, plus another €86 million (euros), in new commitments to private equity, real assets, and private credit funds. Four of the nine commitments went to managers the system had never worked with before. The fund backing those bets is only 47.8% funded. Approving new illiquid, multi-year commitments and disclosing a funding gap that size in the same year isn’t automatically reckless. It’s a decision that deserves more scrutiny than a press release gives it.
I’ve spent 30 years underwriting, structuring, and testifying about exactly these kinds of vehicles as an expert witness in fiduciary litigation, and the question I’d ask before signing off on four new manager relationships in one meeting is simple: does a fund carrying an $83 billion unfunded liability have the oversight bandwidth to monitor four new general partners on top of the ones it already has?
The Teachers’ Retirement System of the State of Illinois committed new capital to Norvestor X, Green Equity Investors X, Volition Capital Fund VI, and Partners Group Infrastructure Secondary at its July meeting, spread across a $13.5 billion private equity portfolio and a $13.4 billion real assets book, alongside four additional private credit and income commitments to managers already in the System’s stable. That kind of build-out is routine for a fund this size running an alternatives program. It’s less routine for a fund managing $86.1 billion in assets against a funded ratio under 50%.
Those numbers aren’t a guess. TRS’s own FY2025 financial report shows the funded ratio, based on actuarial value of assets, rose to 47.8% for the year ended June 30, 2025, up from 45.8% the year before, the fifth straight year of improvement. The same report puts the unfunded liability at $83.1 billion against a $159.1 billion actuarial accrued liability. Five years of gains, and Illinois’ largest teacher fund still can’t cover half of what it owes.
State contributions hit $6.2 billion in fiscal year 2025 alone. TRS’s board finalized the fiscal year 2027 number this past December: $6.59 billion under the statutory funding formula. The same certification shows what the board’s own funding policy, built on its actuary’s recommendation, actually called for: $11.18 billion, nearly double the statutory figure. Illinois funds TRS to the number state law requires, not the number its own actuaries say the math requires, and the board put both figures in writing on the same page. Contributions have still climbed from $3.74 billion just 11 years ago, faster than the 1994 “Edgar ramp” schedule ever projected. Springfield calls that fiscal discipline. I call it a down payment sized to the law rather than to the liability.
The fund earned 9.7% net of fees this past fiscal year, beating its 7% assumed rate of return by 270 basis points, and its board reaffirmed that same 7% assumption at its June 18, 2025 meeting. One good year does not erase a decade of underfunding, and TRS’s own actuaries show exactly what a bad one would cost: drop the discount rate one point, to 6%, and the fund’s net pension liability, a related but separate measure from the unfunded liability above, jumps from $84.8 billion to $105.4 billion, a swing of nearly $20.7 billion from a single percentage point. That is the gap public pension boards get to paper over in a way no ERISA-governed private plan trustee ever could, even one making the same kind of alternative-asset bets TRS just approved.
Illinois can’t shrink its way out of this the way other states have tried. The state constitution treats pension membership as a contractual right that can’t be diminished, and the Illinois Supreme Court’s 2015 ruling in In re Pension Reform Litigation struck down a legislative attempt to trim cost-of-living adjustments and benefit formulas on exactly that ground. The ruling left future benefit accruals for new hires untouched, but it closed the door on retroactively trimming what’s already been promised. That leaves exactly one lever: fund the promise faster than the state has managed for three decades, while the board simultaneously decides how much of that funding gap to bridge with illiquid, long-lockup bets instead of safer assets.
I’ve written elsewhere in this series about New Jersey’s pension debt growing by roughly $2 billion a year and CalPERS carrying $153 billion in unfunded liability. Illinois belongs in that file, with its own variation: a board expanding its alternatives book while the fund’s investments sit well short of solvent.
None of this is about blaming the people TRS pays. TRS reports more than 134,000 benefit recipients, and outside reporting on the system’s membership puts the average retiree at 74.4 years old, collecting roughly $63,000 a year. Those are earned benefits, promised by the state decades before this year’s financial report existed. The question was never whether teachers deserve what they were promised. The question is whether the fund backing that promise and the manager relationships it just added to reach for returns, is built to keep it.
A private-sector 401(k) sponsor approving nine new alternative-asset commitments, four to brand-new managers, while carrying a sub-50% funded ratio would be facing a Department of Labor inquiry, not a routine board vote. Public pension trustees answer to no comparable standard. Illinois just showed exactly what that gap looks like in practice.
