112(3) 113The administrator shall cause an actuarial study of the system to be made at least annually and shall report the results of such study to the Legislature by December 31 prior to the next legislative session. The study shall, at a minimum, conform to the requirements of s. 161112.63, 162with the following exceptions and additions:168(a) 169The valuation of plan assets shall be based on a 5-year averaging methodology such as that specified in the United States Department of Treasury Regulations, 26 C.F.R. s. 1.412(c)(2)-1 in effect on August 16, 2006, or a similar accepted approach designed to attenuate fluctuations in asset values.
216(b) 217The study shall include a narrative explaining the changes in the covered group over the period between actuarial valuations and the impact of those changes on actuarial results.
245(c) 246When substantial changes in actuarial assumptions have been made, the study shall reflect the results of an actuarial assumption as of the current date based on the assumptions utilized in the prior actuarial report.
280(d) 281The study shall include an analysis of the changes in actuarial valuation results by the factors generating those changes. Such analysis shall reconcile the current actuarial valuation results with those results from the prior valuation.
316(e) 317The study shall include measures of funding status and funding progress designed to facilitate the assessment of trends over several actuarial valuations with respect to the overall solvency of the system. Such measures shall be adopted by the department and shall be used consistently in all actuarial valuations performed on the system.
369(f) 370The actuarial model used to determine the adequate level of funding for the Florida Retirement System shall include a specific rate stabilization mechanism, as prescribed herein. It is the intent of the Legislature to maintain as a reserve a specific portion of any actuarial surplus, and to use such reserve for the purpose of offsetting future unfunded liabilities caused by experience losses, thereby minimizing the risk of future increases in contribution rates. It is further the intent of the Legislature that the use of any excess above the reserve to offset retirement system normal costs shall be in a manner that will allow system employers to plan appropriately for resulting cost reductions and subsequent cost increases. The rate stabilization mechanism shall operate as follows:4941. 495The actuarial surplus shall be the value of actuarial assets over actuarial liabilities, as is determined on the preceding June 30 or as may be estimated on the preceding December 31.
5262. 527The full amount of any experience loss shall be offset, to the extent possible, by any actuarial surplus.
5453. 546If the actuarial surplus exceeds 5 percent of actuarial liabilities, one-half of the excess may be used to offset total retirement system costs. In addition, if the actuarial surplus exceeds 10 percent of actuarial liabilities, an additional one-fourth of the excess above 10 percent may be used to offset total retirement system costs. In addition, if the actuarial surplus exceeds 15 percent of actuarial liabilities, an additional one-fourth of the excess above 15 percent may be used to offset total retirement system costs.
6294. 630Any surplus amounts available to offset total retirement system costs pursuant to subparagraph 3. should be amortized each year over a 10-year rolling period on a level-dollar basis.
