ASPRS was established as a single-employer defined benefit pension plan for Arkansas State Troopers in 1951. In the beginning, all ASPRS members participated in a contributory plan whereby employers and employees made contributions to the system. However, Act 793 of 1977 offered employees a choice at that time under the contributory plan. They could remain under the contributory plan or change over to a new non-contributory plan in which only the employer makes contributions to the system. This choice was offered to employees who were ASPRS members at some previous time and returned to work for the system on or after January 1, 1978; however, anyone joining the system on or after January 1, 1978, who was not previously an ASPRS member is automatically covered under the new non-contributory plan.
Act 1071 of 1997 created the Tier Two Benefit Plan for ASPRS (Tier II) for all troopers hired on or after April 3, 1997. Members of the plan in effect before April 3, 1997 (Tier I) had one year from April 3, 1997, to elect participation in Tier II.
Act 1242 of 2009 merged the investable assets of ASPRS with those of the Arkansas Public Employees’ Retirement System (APERS). The act granted all authority over the investment of the merged assets to the Board of Trustees of APERS (APERS Board).
