Experience studies are performed by KPPA's independent actuary to compare each plan's actual experience to what had been expected to occur. State statute requires the CERS and KRS Boards of Trustees to conduct an economic study at least once every two years and a demographic experience study at least once every five years.
Regular experience studies help ensure the underlying economic and demographic assumptions (such as expected payroll growth, investment returns and retiree life expectancy) accurately reflect plan experience. Accuracy is important because these assumptions are used to calculate the annual employer contribution rate that will allow KPPA to pay for current and future retiree benefits.
