Milliman recently released results for its Public Pension Funding Index (PPFI), which covers the nation’s 100 largest public defined benefit plans.

Positive equity market performance in September increased the Milliman 100 PPFI funded ratio from 82.0% at the end of August to 82.8% as of September 30, representing the highest level since March 31, 2022, prior to the Fed’s aggressive rate increases. The previous high-water mark stood at 82.7%. The improved funding for Milliman’s PPFI plans was driven by an estimated 1.4% aggregate return for September 2024 (9.4% for the YTD period). Total fund performance for these 100 public plans ranged from an estimated 0.7% to 2.1% for the month. As a result of the relatively strong performance, PPFI plans gained approximately $72 billion in MV during the latest month. The asset growth was offset by negative cash flow amounting to about $10 billion. It is estimated that the current asset shortfall relative to accrued liabilities is about $1.138 trillion as of September 30. 

In addition, it was reported that an additional 5 of the PPFI members had achieved a 90% or better funded status (34 plans have now eclipsed this level), while regrettably, 14 of the constituents remain at <60%. Given that changing US interest rates do not impact the calculation for pension liabilities under GASB accounting, which uses the ROA as the liability discount rate, the improvement in the collective funded status may be overstated, as US rates continued to decline throughout the third quarter following an upward trajectory to start the calendar year.
