Voluntary employee contributions.
(iv) Voluntary employee contributions. If voluntary employee contributions are made to the plan, the portion of the plan to which voluntary employee contributions are made is treated as a defined contribution plan pursuant to section 414(k) and, accordingly, is a defined contribution plan pursuant to 1.415(c)-1(a)(2)(i). Accordingly, the portion of a plan to which voluntary employee contributions are made is not a defined benefit plan within the meaning of paragraph (a)(2) of this section and is not taken into account in determining the annual benefit under the portion of the plan that is a defined benefit plan.
