Description of Proposed Provision:
A3: Starting December 2018, compute the COLA using a chained version of the consumer price index for wage and salary workers (CPI-W). We estimate this new computation will reduce the annual COLA by about 0.3 percentage point, on average.

Estimates based on the intermediate assumptions of the 2017 Trustees Report
