Description of Proposed Provision:
B3.12: Use an annualized "mini-PIA" formula beginning with retired workers newly eligible in 2031. For each indexed earnings year, compute an individual AIME and an individual PIA. Sum these individual PIAs for the 40 highest years of indexed earnings and divide that total amount by 37 to get the PIA for this provision. Phase-in over five years, meaning that in 2031, 80 percent of the benefit would be based on the old 35-year average PIA formula and 20 percent on the new mini-PIA formula, shifting by 20 percentage points each year until 100 percent is based on the new mini-PIA formula for those attaining age 62 in 2035. Disabled worker benefits are unchanged under this provision.
