A new report said the University of Wisconsin System overpaid health insurance premiums and pension contributions by nearly $33 million in 2011 and 2012.
The Legislative Audit Bureau released a report Thursday that found the system overpaid health premiums by $15.4 million from May 2011 through September 2012. The report found $8 million in overpayments went to premiums for 924 employees who had been fired during that span. The system had been able to recover only $228,000 as of October.
The report also found the system overpaid $17.5 million in retirement contributions in 2011. The state Department of Employee Trust Funds has credited the system for the overpayments.
The report said system officials failed to reconcile the amount of premiums collected with coverage and made manual mistakes calculating retirement contributions.
