§ 2530.204-1 Year of participation for benefit accrual.
(a) General. Section 204(b)(1) of the Act and section 411(b)(1) of the Code contain certain requirements relating to benefit accrual under a defined benefit pension plan. Some of these requirements are based on the number of years of participation included in an employee's period of service. Paragraph (b) of this section relates to service which must be taken into account in determining an employee's period of service for purposes of benefit accrual. Section 2530.204–2 sets forth rules relating to the computation periods to be used in measuring years of participation for benefit accrual (“accrual computation periods”).
(b) Service which may be disregarded for purposes of benefit accrual. (1) In calculating an employee's period of service for purposes of benefit accrual under a defined benefit pension plan, section 204(b)(3) of the Act and section 411(b)(3) of the Code permit the following service to be disregarded: service before an employee first becomes a participant in the plan; service which is not required to be taken into account under section 202(b) of the Act and section 410(b)(5) of the Code (relating to one-year breaks in service for purposes of eligibility to participate); and service which is not required to be taken into account under section 204(b)(3)(C) of the Act and section 411(b)(3)(C) of the Code (relating to 12-consecutive-month periods during which an employee's service is less than 1,000 hours). In addition, in calculating an employee's period of service for purposes of benefit accrual, a defined benefit plan shall not be required to take into account service before the conclusion of a series of consecutive 1-year breaks in service occurs which permits a plan to disregard prior service under section 203(b)(3)(D) of the Act and section 411(a)(6)(D) of the Code.
