Experience Studies

‚ÄčExperience studies are performed by the Systems' independent actuary at least every five years to compare each plan's actual experience to what had been expected to occur. 

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 KRS to pay for current and future retiree benefits.

The two most recent Experience Studies, along with a presentation given to the Board of Trustees explaining the results of the 2013 Study, are listed below.


All documents prior to 2013 have been archived and are available upon request. In addition, alternate formats of these materials may be made available upon request. Persons with hearing and speech impairments can contact KRS by using the Kentucky Relay Service, a toll-free telecommunication device for the deaf (TDD). For voice to TDD, call 800-648-6057.
