Rules of application
(2) Rules of application(i) Consistency requirement. Both normal and most valuable accrual rates must be determined in a consistent manner for all employees for the plan year. Thus, for example, the same measurement periods must be used, and the rules of this paragraph (d)(2) and any available options described in paragraph (d)(3) of this section must be applied consistently. If plan benefits are not expressed as straight life annuities beginning at employees' testing ages, they must be normalized. (ii) Determining plan benefits, service and compensation(A) In general. Potential plan benefits, testing service, and average annual compensation must be determined in a reasonable manner, reflecting actual or projected service and compensation only through the end of the measurement period. The determination of potential plan benefits is not reasonable if it incorporates an assumption that, in future years, an employee's compensation will increase or the employee will terminate employment before the employee's testing age (other than the assumptions under paragraph (d)(1)(ii) of this section that the employee's service will end in connection with the payment of each potential QJSA in future years). (B) Section 415 limits. For purposes of determining accrual rates under this paragraph (d), plan benefits are generally determined without regard to whether those benefits are permitted to be paid under section 415. However, plan provisions implementing any of the limits of section 415 may be taken into account in applying this paragraph (d) if the plan does not provide for benefit increases resulting from section 415(d)(1) adjustments for former employees who were employees in a plan year in which such plan provisions were taken into account in applying this paragraph (d). If the limits of section 415 are taken into account under this paragraph (d)(2)(ii)(B) as of the end of the measurement period, they must also be taken into account as of the beginning of the measurement period. If the limits of section 415 are not taken into account in testing the plan for the current plan year, but were taken into account in testing the plan for the preceding plan year, any resulting increase in the accrued benefits taken into account in testing the plan is treated as an increase in accrued benefits during the current plan year. (iii) Requirements for measurement period that includes future years(A) Discriminatory pattern of accruals. A measurement period that includes future years (as described in paragraph (d)(1)(iii)(C) of this section) may not be used if the pattern of accruals under the plan discriminates in favor of HCEs (i.e., if projected benefits for HCEs are relatively frontloaded when compared to the degree of front loading or backloading for NHCEs). This determination is made based on all of the relevant facts and circumstances. (B) Future-period limitation. Future years beginning after an employee's attainment of the employee's testing age (or after the employee's assumed termination in the case of most valuable accrual rates) may not be included in the measurement period. (3) Optional rules(i) Imputation of permitted disparity. The disparity permitted under section 401(l) may be imputed in accordance with the rules of 1.401(a)(4)-7. (ii) Grouping of accrual rates(A) General rule. An employer may treat all employees who have accrual rates within a specified range above and below a midpoint rate chosen by the employer as having an accrual rate equal to the midpoint rate within that range. Accrual rates within a given range may not be grouped under this paragraph (d)(3)(ii) if the accrual rates of HCEs within the range generally are significantly higher than the accrual rates of NHCEs in the range. The specified ranges within which all employees are treated as having the same accrual rate may not overlap and may be no larger than provided in paragraph (d)(3)(ii)(B) of this section. Accrual rates of employees that are not within any of these specified ranges are determined without regard to this paragraph (d)(3)(ii). (B) Size of specified ranges. In the case of normal accrual rates, the lowest and highest accrual rates in the range must be within five percent (not five percentage points) of the midpoint rate. In the case of most valuable accrual rates, the lowest and highest accrual rates in the range must be within 15 percent (not 15 percentage points) of the midpoint rate. If accrual rates are determined as a percentage of average annual compensation, the lowest and highest accrual rates need not be within five percent (or 15 percent) of the midpoint rate, if they are no more than one twentieth of a percentage point above or below the midpoint rate. (iii) Fresh-start alternative(A) General rule. Notwithstanding the definition of measurement period provided in paragraph (d)(1)(iii) of this section, a measurement period for a fresh-start group is permitted to be limited to the period beginning after the fresh-start date with respect to that group if the plan makes a fresh start that satisfies 1.401(a)(4)-13(c) (without regard to 1.401(a)(4)-13(c)(2)(i) and (ii)). If the measurement period is so limited or the measurement period is the plan year (whether or not so limited), any compensation adjustments during the measurement period to the frozen accrued benefit as of the fresh-start date that are permitted under the rules of 1.401(a)(4)-13(d) may be disregarded in determining the increase in accrued benefits during the measurement period, but only if
