Key Takeaways
  • • California Public Employees' Retirement System (CalPERS), the nation's largest public pension fund with $630 billion in assets serving 2.4 million members, ranks in the bottom 15% of all 230 U.S. public pension funds for both five- and 10-year returns, according to an independent investigation commissioned by the Retired Public Employees Association of California.
  • • Approximately 9% of CalPERS' portfolio is allocated to aging private equity partnerships (zombie funds) that struggle to monetize underlying investments while continuing to extract management fees with minimal or no return generation for beneficiaries.
  • • CalPERS leadership compensation structure appears misaligned with fund performance: four executives earn exceeding $1 million annually, four others earn above $900,000, and 26 staff members earn between $500,000 and $900,000, despite chronic underperformance.
  • • The independent probe identified systemic opacity, understated investment costs, and conflicts of interest as material risks to 2.4 million beneficiaries, prompting advocacy groups to call for the establishment of an independent inspector general office with subpoena authority to oversee the fund.
  • • The investigation was independently funded and conducted by a former SEC lawyer after state legislators declined to order an official audit or establish independent oversight, highlighting governance gaps at the nation's largest public pension system.
Summary
An independent investigation into the California Public Employees' Retirement System (CalPERS), the nation's largest public pension fund with $630 billion in assets, has exposed significant performance deficiencies, operational opacity, and governance concerns affecting 2.4 million beneficiaries. The Retired Public Employees Association of California commissioned the probe through a former Securities and Exchange Commission lawyer after unsuccessful attempts to persuade state legislators to authorize an official audit or create an independent inspector general office.

The investigation's core findings reveal systemic underperformance and cost opacity. CalPERS' investment returns placed the fund in the bottom 15% of all 230 U.S. public pension funds for both five- and 10-year measurement periods—a material shortfall for a fund of this scale and mandate. Additionally, approximately 9% of CalPERS' portfolio remains invested in aging private equity partnerships, colloquially termed "zombie funds," which are experiencing difficulty liquidating portfolio companies while continuing to consume management fees with minimal or no investor returns. These findings suggest significant drag on long-term beneficiary outcomes and raise questions about portfolio rebalancing discipline and fee transparency.

Compensation practices at CalPERS appear disconnected from fund performance outcomes. The organization employs four executives earning in excess of $1 million annually, another four earning above $900,000, and 26 staff members earning between $500,000 and $900,000. Margaret Brown, president of the Retired Public Employees Association and former CalPERS board member, characterized these compensation levels as "excessive" given the fund's underperformance and noted concerns regarding "potentially hidden costs and fees."

Brown stated the advocacy group's position directly: "Between chronic underperformance, potentially hidden costs and fees, we are extremely concerned by the risks in the fund. This is why we need the Office of the Inspector General, somebody independent with subpoena powers, to get the records to investigate." The independent investigation underscores governance gaps at CalPERS, where lack of external oversight and transparency mechanisms has enabled structural inefficiencies to persist without adequate institutional accountability to beneficiaries.
