Category of Change: Level of Monthly Benefits (PIA)

Change in 

Actuarial Balance

Proposed Provision: Progressive price indexing of PIA formula factors beginning with individuals newly

eligible for OASI benefits in 2012. Create new bend point at the 30th percentile of earners. Maintain 

current-law benefits for earners at the 30th percentile and below and reduce upper 2 formula factors 

(32% and 15%) such that maximum worker benefit grows by inflation rather than the growth in average 

wages. Disability benefits are not affected by the proposal. Disabled worker beneficiaries, upon 

attaining normal retirement age, would be subject to a proportional reduction in benefits based on the 

worker's years of disability.
