Proposed Provision: Progressive indexing (30th percentile) of PIA factors beginning with individuals newly eligible for OASI benefits in 2017, continuing through 2054, and resuming in 2075: Create a new bend point at the 30th percentile of the AIME distribution of newly retired workers. Maintain current-law benefits for earners at the 30th percentile and below. Reduce the 32 and 15 percent factors above the 30th percentile such that the initial benefit for a worker with AIME equal to the taxable maximum is reduced by 1.13 percent per year as compared to current law (for the years that progressive indexing applies). Disabled workers are: (a) not affected prior to normal retirement age; and (b) subject to a proportional reduction in benefits, based on the worker's years of disability, upon conversion to retired-worker beneficiary status.
