Example: Mr. Jones, a railroad employee, becomes entitled to an age annuity in June 1986, at the age of 62. Although Mr. Jones has earnings of $23,000 in the first five months of 1986, those earnings cannot be used in the initial computation of the Tier I PIA. However, effective with January 1, 1987, the Tier I PIA is recomputed to include the earnings for 1986.
