The discovery came to light in a trove of documents obtained by reporters that found a tiny discrepancy that boosted the $64 billion Public School Employees Retirement System (PSERS) by a third of a percentage point in April of that year.
The consultant firm hired to review PSERS’ investment returns between 2011 and 2020, ACA Compliance Group, performed limited checks that skipped over the month in question, according to the report. The company that crunched the actual numbers, Aon, blamed the discrepancy on a data entry error.
No matter the fault, the miscalculation unraveled PSERS’ rate of return, dropping it from just above the mandated 6.36% threshold to prevent a contribution increase down to 6.34%. Now, about 100,000 workers who joined the system in 2011 or later will pay more beginning on July 1.
