In general, for purposes of determining whether a defined contribution plan or a defined benefit plan maintained by a railroad employer and covering employees described in te preceding sentence, satisfies section 401(l), the employer-derived portion of an employee's tier 2 benefits and supplementary annuity benefits under the Railroad Retirement Act of 1974 are treated as though such benefits were provided by the railroad employer under a qualified plan.

(ii) Railroad retirement covered compensation for an employee means 12 multiplied by the average of the 60 highest monthly railroad retirement taxable wage bases in effect for the employee's period of employment. The monthly railroad retirement taxable wage base is determined by dividing the railroad retirement taxable wage base for the calendar year in which the month occurs by 12. An employee's railroad retirement covered compensation for the plan year is determined as of the beginning of the plan year. A plan must provide that an employee's railroad retirement covered compensation is automatically adjusted for each plan year. See § 1.401(l)-1(b) for rules relating to prohibited decreases in an employee's accrued benefit within the meaning of section 411(d)(6) or section 411(b)(1)(G).

(i) “Railroad retirement covered compensation” is substituted for “covered compensation” in § 1.401(l)-3(d),
(ii) The reductions under § 1.401(l)-3(d) are made by multiplying the 0.56-percent factor by the ratio of the applicable factor from the table in § 1.401(l)-(3)(d)(9)(iv)(A) to 0.75, and
(iii) The following tables are substituted for Tables I through III set forth in § 1.401(l)-3(e)(3).
