"The WEP PIA replicates the regular PIA but scales down the first percentage from 90 percent to 40 percent in increments of five percentage points for workers with less than 30 years of coverage (YOCs).
Thus, workers with 30 or more YOCs have a first PIA factor of 90 percent, workers with 21-29 YOCs have a first PIA factor between 45-85 percent, and workers with 20 YOCs have a first PIA factor of 40 percent."
