121.182  Retirement annuities authorized for county personnel.--Counties are authorized to purchase annuities for all county personnel with 25 or more years of creditable service who have reached age 50 and have applied for retirement under the Florida Retirement System. No such annuity shall provide for more than the total difference in retirement income between the retirement benefit based on average monthly compensation and creditable service as of the member's early retirement date and the early retirement benefit. Counties may also purchase annuities for members of the Florida Retirement System who have out-of-state service in another state or country which is documented as valid by the appropriate county. Such annuities may be based on no more than 5 years of out-of-state service and may equal, but not exceed, the benefits that would be payable under the Florida Retirement System if credit for out-of-state service was authorized under that system. Counties are authorized to invest funds, purchase annuities, or provide local supplemental retirement programs for purposes of providing annuities for county personnel. All retirement annuities shall comply with s. 14, Art. X of the State Constitution.
