(b) To annuitant. The agency should advise the annuitant in writing, generally, of the effect reemployment has on annuitant status and/or the continued receipt of annuity, the possible, future retirement benefits that may be payable to an annuitant on the basis of reemployment, and, for CSRS annuitants, whether the annuitant may elect to have retirement deductions withheld from his or her basic pay.

(1) Whether the annuitant is then in receipt of annuity;

(2) The gross monthly amount of annuity the annuitant is then receiving;

(3) Whether the annuitant is a disability annuitant, and if so, whether OPM has found the annuitant recovered from his or her disability, or restored to earning capacity; and.

(4) If the annuitant is a CSRS annuitant, whether the annuitant's retirement was based on an involuntary separation, not for charges of misconduct or delinquency.
