1. (a) A member of tier II may elect one of the following optional forms for retirement income by filing with the Retirement Commission a written election on a form provided by the commission. A member who has been married at least one year will be presumed to elect the option offered under subdivision (1) of this subsection unless a contrary election is made by the member. All other members will be presumed to elect the option offered under subdivision (4) of this subsection unless a contrary election is made by the member. Any election or change of election must be filed before retirement income payments begin. No option shall be effective until a member has retired, and in the event a member dies prior to the date benefits would have commenced, any election of an option shall be deemed cancelled except as provided in subsection (c) of section 5-192r. The amount of income that will be paid under the options will be determined by multiplying the retirement income as determined under sections 5-192l to 5-192p, inclusive, as applicable, by the actuarially equivalent option factors last adopted by the Retirement Commission. Such factors shall be identical to those provided under section 5-165 unless the Retirement Commission shall determine otherwise. The factors may be periodically adjusted upward or downward by the Retirement Commission to reflect changing interest, mortality, or election of option patterns, provided that they shall be reviewed and adjusted by January 1, 1985. Any such changes shall apply only to members whose benefits commence after the effective date of adoption of such factors. The retirement options are as follows:

   1. (1) A reduced amount payable to the member for his lifetime, with the provision that after his death his spouse, if surviving, shall be entitled to receive a lifetime income equal to fifty per cent of the reduced monthly amount payable to the member; (2) a reduced amount payable to the member for his lifetime, with the provision that after his death, his contingent annuitant shall be entitled to receive a lifetime income equal to either fifty or one hundred per cent of the reduced amount payable to the member; (3) a reduced amount payable to the member for his lifetime, with the provision that if he shall die within either a ten or twenty-year period following the date his retirement income commences, whichever is selected by the member, the reduced amount continues to his contingent annuitant for the balance of the ten or twenty-year period, respectively; or (4) an amount payable to the member for his lifetime, with no payments continuing after the member's death.

2. (b) Notwithstanding the provisions of subsection (a) of this section, a temporary minimum shall apply whenever the Retirement Commission adopts revised factors which could result in a smaller benefit to a member than would have been payable under the previously existing factors. Such minimum shall be determined as follows:

   1. (1) The benefit the member had earned as of the date of the change in factors shall be calculated, based on his final average earnings and credited service or based on his vesting service as of that date; (2) any early retirement reduction in such benefit shall be based upon his age as determined on the date benefits will commence, and his type of retirement; and (3) the option factor shall be determined utilizing the factors in effect prior to such change, but based on appropriate ages as of the date benefits will commence. If such minimum results in a larger benefit, the larger benefit shall be payable.
