Before October 1, 1982, when a CSRS annuitant retired before age 62, OPM credited
post-1956 MS in the CSRS annuity computation. If the CSRS annuitant later became eligible
for a Social Security benefit that included credit for post-1956 MS, OPM recomputed
the annuity to exclude the MS effective with the month of Social Security eligibility.
If a CSRS annuity began in or after the month of Social Security eligibility, OPM
did not use the post-1956 MS in the initial annuity computation.
NOTE: For CSRS annuity recomputation purposes, OPM considered the month of Social Security
eligibility to be the month:
-
•
of attainment of age 62 for retirement benefits;
-
•
of attainment of age 65 for disability benefits; or
-
•
the number holder’s death for survivor benefits.
