(a) Employee annuity.
A supplemental annuity that begins after December 31, 1974, does not affect the payment of a regular employee annuity. A supplemental annuity beginning prior to 1975 causes a reduction in the employee annuity as provided by section 3(j) of the Railroad Retirement Act of 1937.
(b) Spouse or survivor annuity.
The payment of a supplemental annuity does not affect the amount of a spouse or survivor annuity.
(c) Residual lump-sum.
The amount of a supplemental annuity is not deducted from the gross residual lump-sum benefit. See part 234 of this chapter for an explanation of the residual lump-sum benefit.
