The reliability measures show the likely range of values for the IP indexes after their fifth and final monthly
revision. The 15th (85th) percentile estimate is equal to the current estimate plus an amount such that the
equivalent measure revised by a lower (higher) amount for only 15 percent of the months since 2008. More
