Computation.
(1) A redetermined annuity is computed using all the reemployed annuitant's creditable service, under the provisions of law in effect governing the payment of CSRS and/or FERS annuities, as may be applicable, at the time of separation from reemployment service, or conversion to intermittent status.
(2) The amount of the redetermined annuity of an individual whose previous annuity was terminated under the provisions of ยง 837.202(b)(1)(iii) of this part will at least equal the amount of the terminated annuity plus any increases under section 8340 of title 5, United States Code, occurring after the termination of the previous annuity and before the commencement of the redetermined annuity, adjusted by any annuity increase or reduction resulting from additional or different elections made by the reemployed annuitant.
