(2) The recalculated retirement allowance shall be the basis on which future adjustments to the retirement allowance are calculated.

(3) The supplement provided by this section shall be calculated pursuant to subsection (1) and shall be paid before October 1, 1996.

If a retirant dies before October 1, 1996 and no benefits become payable under section 506 or 508,  1 the retirant's retirement allowance shall not be supplemented under this section.

(4) This section does not apply to a retirant or beneficiary of a deceased retirant who received a supplement under section 16a of the former probate judges retirement system.  2
