Proposed Provision: Starting with the December 2011 cost-of-living adjustment (COLA), compute the COLA using a chained version of the consumer price index for wage and salary workers (CPI-W). This new computation is estimated to result in an annual COLA that is 0.3 percentage point less, on average.
