1.401(a)(4)-3—Nondiscrimination in amount of employer-provided benefits under a defined benefit plan.

(a) Introduction— (1) Overview. This section provides rules for determining whether the employer-provided benefits under a defined benefit plan are nondiscriminatory in amount as required by § 1.401(a)(4)-1(b)(2)(iii). Certain defined benefit plans that provide uniform benefits are permitted to satisfy this requirement by meeting one of the safe harbors in paragraph (b) of this section. Plans that do not provide uniform benefits may satisfy this requirement by satisfying the general test in paragraph (c) of this section. Paragraph (d) of this section provides rules for determining the individual benefit accrual rates needed for the general test. Paragraph (e) of this section provides rules for determining compensation for purposes of applying the requirements of this section. Paragraph (f) of this section provides additional rules that apply generally for purposes of both the safe harbors in paragraph (b) of this section and the general test in paragraph (c) of this section. See § 1.401(a)(4)-6 for rules for determining the amount of employer-provided benefits under a contributory DB plan, and for determining whether the employee-provided benefits under such a plan are nondiscriminatory in amount.
(2) Alternative methods of satisfying nondiscriminatory amount requirement. A defined benefit plan is permitted to satisfy paragraph (b) or (c) of this section on a restructured basis pursuant to § 1.401(a)(4)-9(c). Alternatively, a defined benefit plan is permitted to satisfy the nondiscriminatory amount requirement of § 1.401(a)(4)-1(b)(2)(iii) on the basis of equivalent allocations pursuant to § 1.401(a)(4)-8(c). In addition, a defined benefit plan that is part of a floor-offset arrangement is permitted to satisfy this section pursuant to § 1.401(a)(4)-8(d).
(b) Safe harbors— (1) In general. The employer-provided benefits under a defined benefit plan are nondiscriminatory in amount for a plan year if the plan satisfies each of the uniformity requirements of paragraph (b)(2) of this section and any one of the safe harbors in paragraphs (b)(3) (unit credit plans), (b)(4) (fractional accrual plans), and (b)(5) (insurance contract plans) of this section. Paragraph (b)(6) of this section provides exceptions for certain plan provisions that do not cause a plan to fail to satisfy this paragraph (b). Paragraph (f) of this section provides additional rules that apply in determining whether a plan satisfies this paragraph (b).
(2) Uniformity requirements— (i) Uniform normal retirement benefit. The same benefit formula must apply to all employees. The benefit formula must provide all employees with an annual benefit payable in the same form commencing at the same uniform normal retirement age. The annual benefit must be the same percentage of average annual compensation or the same dollar amount for all employees who will have the same number of years of service at normal retirement age. (See § 1.401(a)(4)-1 1(d)(3) regarding service that may be taken into account as years of service.) The annual benefit must equal the employee's accrued benefit at normal retirement age (within the meaning of section 411(a)(7)(A)(i)) and must be the normal retirement benefit under the plan (within the meaning of section 411(a)(9) ).
(ii) Uniform post-normal retirement benefit. With respect to an employee with a given number of years of service at any age after normal retirement age, the annual benefit commencing at that employee's age must be the same percentage of average annual compensation or the same dollar amount that would be payable commencing at normal retirement age to an employee who had that same number of years of service at normal retirement age.
(iii) Uniform subsidies. Each subsidized optional form of benefit available under the plan must be currently available (within the meaning of § 1.401(a)(4)-4(b)(2)) to substantially all employees. Whether an optional form of benefit is considered subsidized for this purpose may be determined using any reasonable actuarial assumptions.
(iv) No employee contributions. The plan must not be a contributory DB plan.
(v) Period of accrual. Each employee's benefit must be accrued over the same years of service that are taken into account in applying the benefit formula under the plan to that employee. For this purpose, any year in which the employee benefits under the plan (within the meaning of § 1.410(b)-3(a)) is included as a year of service in which a benefit accrues. Thus, for example, a plan does not satisfy the safe harbor in paragraph (b)(4) of this section unless the plan uses the same years of service to determine both the normal retirement benefit under the plan's benefit formula and the fraction by which an employee's fractional rule benefit is multiplied to derive the employee's accrued benefit as of any plan year.
(vi) Examples. The following examples illustrate the rules in this paragraph (b)(2):

Code of Federal Regulations

Example 1. Plan A provides a normal retirement benefit equal to two percent of average annual compensation times each year of service commencing at age 65 for all employees. Plan A provides that employees of Division S receive their benefit in the form of a straight life annuity and that employees of Division T receive their benefit in the form of a life annuity with an automatic cost-of-living increase. Plan A does not provide a uniform normal retirement benefit within the meaning of paragraph (b)(2)(i) of this section because the annual benefit is not payable in the same form to all employees.

Code of Federal Regulations

Example 2. Plan B provides a normal retirement benefit equal to 1.5 percent of average annual compensation times each year of service at normal retirement age for all employees. The normal retirement age under the plan is the earlier of age 65 or the age at which the employee completes 10 years of service, but in no event earlier than age 62. Plan B does not provide a uniform normal retirement benefit within the meaning of paragraph (b)(2)(i) of this section because the same uniform normal retirement age does not apply to all employees.

Code of Federal Regulations

Example 3. Plan C is an accumulation plan under which the benefit for each year of service equals one percent of plan year compensation payable in the same form to all employees commencing at the same uniform normal retirement age. Under paragraph (e)(2) of this section, an accumulation plan may substitute plan year compensation for average annual compensation. Plan C provides a uniform normal retirement benefit within the meaning of paragraph (b)(2)(i) of this section, because all employees with the same number of years of service at normal retirement age will receive an annual benefit that is treated as the same percentage of average annual compensation.

Code of Federal Regulations

Example 4. The facts are the same as in Example 3, except that the benefit for each year of service equals one percent of plan year compensation increased by reference to the increase in the cost of living from the year of service to normal retirement age. Plan C does not provide a uniform normal retirement benefit, because the annual benefit defined by the benefit formula can vary for employees with the same number of years of service at normal retirement age, depending on the age at which those years of service were credited to the employee under the plan.

Code of Federal Regulations

Example 5. Plan D provides a normal retirement benefit of 50 percent of average annual compensation at normal retirement age (age 65) for employees with 30 years of service at normal retirement age. Plan D provides that, in the case of an employee with less than 30 years of service at normal retirement age, the normal retirement benefit is reduced on a pro rata basis for each year of service less than 30. However, if an employee with less than 30 years of service at normal retirement age continues to work past normal retirement age, Plan D provides that the additional years of service worked past normal retirement age are taken into account for purposes of the 30 years of service requirement. Thus, an employee who has 26 years of service at age 65 but who does not retire until age 69 with 30 years of service will receive a benefit of 50 percent of average annual compensation. Plan D provides uniform post-normal retirement benefits within the meaning of paragraph (b)(2)(ii) of this section.
Code of Federal Regulations 113

Code of Federal Regulations

Example 6. (a) Plan E is amended on February 14, 1994, to provide an early retirement window benefit that consists of an unreduced early retirement benefit to employees who terminate employment after attainment of age 55 with 10 years of service and between June 1, 1994, and November 30, 1994. The early retirement window benefit is a single subsidized optional form of benefit. Paragraph (b)(2)(iii) of this section requires that the subsidized optional form of benefit be currently available (within the meaning of § 1.401(a)(4)-4(b)(2) ) to substantially all employees. Section 1.401(a)(4)-4(b)(2)(ii)(A) (2) provides that age and service requirements are not disregarded in determining the current availability of an optional form of benefit if those requirements must be satisfied within a specified period of time. Thus, the early retirement window benefit is not currently available to an employee unless the employee will satisfy the eligibility requirements for the early retirement window benefit by the close of the early retirement window benefit period. Plan E will fail to satisfy paragraph (b)(2)(iii) of this section unless substantially all of the employees satisfy the eligibility requirements for the early retirement window benefit by November 30, 1994. However, see § 1.401(a)(4)-9(c)(6) , Example 2, for an example of how a plan with an early retirement window benefit may be restructured into two component plans, each of which satisfies the safe harbors of this paragraph (b). (b) A similar analysis would apply if, instead of an unreduced early retirement benefit, the early retirement window benefit consisted of a special schedule of early retirement factors, defined by starting with the plan's usual schedule and then treating each employee eligible for the early retirement window benefit as being five years older than the employee actually is, but not older than the employee's normal retirement age.

Code of Federal Regulations

Example 7. Plan F generally provides a normal retirement benefit of 1.5 percent of an employee's average annual compensation multiplied by the employee's years of service with the employer. For employees transferred outside of the group of employees covered by the plan, the plan's benefit formula takes into account only years of service prior to the transfer, but determines average annual compensation taking into account section 414(s) compensation both before and after the transfer. Plan F does not satisfy the requirements of paragraph (b)(2)(v) of this section with respect to transferred employees, because their benefits are accrued over years of service (i.e., after transfer) that are not taken into account in applying the plan's benefit formula to them. However, see Example 2 of paragraph (b)(6)(x)(B) of this section for an example of how a plan that continues to take transferred employees' section 414(s) compensation into account after their transfer may still satisfy this paragraph (b).
(3) Safe harbor for unit credit plans— (i) General rule. A plan satisfies the safe harbor in this paragraph (b)(3) for a plan year if it satisfies both of the following requirements:
(A) The plan must satisfy the 133 1/3 percent accrual rule of section 411(b)(1)(B).
(B) Each employee's accrued benefit under the plan as of any plan year must be determined by applying the plan's benefit formula to the employee's years of service and (if applicable) average annual compensation, both determined as of that plan year.
(ii) Example. The following example illustrates the rules in this paragraph (b)(3):

Code of Federal Regulations

Example. Plan A provides that the accrued benefit of each employee as of any plan year equals the employee's average annual compensation times a percentage that depends on the employee's years of service determined as of that plan year. The percentage is 2 percent for each of the first 10 years of service, plus 1.5 percent for each of the next 10 years of service, plus 2 percent for all additional years of service. Plan A satisfies this paragraph (b)(3).
(4) Safe harbor for plans using fractional accrual rule— (i) General rule. A plan satisfies the safe harbor in this paragraph (b)(4) for a plan year if it satisfies each of the following requirements:
(A) The plan must satisfy the fractional accrual rule of section 411(b)(1)(C).
(B) Each employee's accrued benefit under the plan as of any plan year before the employee reaches normal retirement age must be determined by multiplying the employee's fractional rule benefit (within the meaning of § 1.411(b)-1(b)(3)(ii)(A)) by a fraction, the numerator of which is the employee's years of service determined as of the plan year, and the denominator of which is the employee's projected years of service as of normal retirement age.
(C) The plan must satisfy one of the following requirements:
(1) Under the plan, it must be impossible for any employee to accrue in a plan year a portion of the normal retirement benefit described in paragraph (b)(2)(i) of this section that is more than one-third larger than the portion of the same benefit accrued in that or any other plan year by any other employee, when each portion of the benefit is expressed as a percentage of each employee's average annual compensation or as a dollar amount. In making this determination, actual and potential employees in the plan with any amount of service at normal retirement must be taken into account (other than employees with more than 33 years of service at normal retirement age). In addition, in the case of a plan that satisfies section 401(l) in form, an employee is treated as accruing benefits at a rate equal to the excess benefit percentage in the case of a defined benefit excess plan or at a rate equal to the gross benefit percentage in the case of an offset plan.
(2) The normal retirement benefit under the plan must be a flat benefit that requires a minimum of 25 years of service at normal retirement age for an employee to receive the unreduced flat benefit, determined without regard to section 415. For this purpose, a flat benefit is a benefit that is the same percentage of average annual compensation or the same dollar amount for all employees who have a minimum number of years of service at normal retirement age (e.g., 50 percent of average annual compensation), with a pro rata reduction in the flat benefit for employees who have less than the minimum number of years of service at normal retirement age. An employee is permitted to accrue the maximum benefit permitted under section 415 over a period of less than 25 years, provided that the flat benefit under the plan, determined without regard to section 415, can accrue over no less than 25 years.
(3) The plan must satisfy the requirements of paragraph (b)(4)(i)(C)(2) of this section (other than the requirement that the minimum number of years of service for receiving the unreduced flat benefit is at least 25 years), and, for the plan year, the average of the normal accrual rates for all nonhighly compensated nonexcludable employees must be at least 70 percent of the average of the normal accrual rates for all highly compensated nonexcludable employees. The averages in the preceding sentence are determined taking into account all nonexcludable employees (regardless of whether they benefit under the plan). In addition, contributions and benefits under other plans of the employer are disregarded. For purposes of this paragraph (b)(4)(i)(C)(3 ), normal accrual rates are determined under paragraph (d) of this section.
(ii) Examples. The following examples illustrate the rules in this paragraph (b)(4). In each example, it is assumed that the plan has never permitted employee contributions.

Code of Federal Regulations

Example 1. Plan A provides a normal retirement benefit equal to 1.6 percent of average annual compensation times each year of service up to 25. Plan A further provides that an employee's accrued benefit as of any plan year equals the employee's fractional rule benefit multiplied by a fraction, the numerator of which is the employee's years of service as of the plan year, and the denominator of which is the employee's projected years of service as of normal retirement age. The greatest benefit that an employee could accrue in any plan year is 1.6 percent of average annual compensation (this is the case for an employee with 25 or fewer years of projected service at normal retirement age). Among potential employees with 33 or fewer years of projected service at normal retirement age, the lowest benefit that an employee could accrue in any plan year is 1.212 percent of average annual compensation (this is the case for an employee with 33 years of projected service at normal retirement age). Plan A satisfies paragraph (b)(4)(i)(C)(1) of this section because 1.6 percent is not more than one third larger than 1.212 percent.

Code of Federal Regulations

Example 2. Plan B provides a normal retirement benefit equal to 1.0 percent of average annual compensation up to the integration level, and 1.6 percent of average annual compensation above the integration level, times each year of service up to 35. Plan B further provides that an employee's accrued benefit as of any plan year equals the employee's fractional rule benefit multiplied by a fraction, the numerator of which is the employee's years of service as of the plan year and the denominator of which is the employee's projected years of service as of normal retirement age. For purposes of satisfying the one third larger rule in paragraph (b)(4)(i)(C)(1) of this section, because Plan B satisfies section 401(l) in form, all employees with less than 35 projected years of service are assumed to accrue benefits at the rate of 1.6 percent of average annual compensation (the excess benefit percentage under the plan). Plan B satisfies paragraph (b)(4)(i)(C) of this section because all employees with 33 or fewer years of projected service at normal retirement age accrue in each plan year a benefit of 1.6 percent of average annual compensation.
Code of Federal Regulations 115

Code of Federal Regulations

Example 3. Plan C provides a normal retirement benefit equal to four percent of average annual compensation times each year of service up to 10 and one percent of average annual compensation times each year of service in excess of 10 and not in excess of 30. Plan C further provides that an employee's accrued benefit as of any plan year equals the employee's fractional rule benefit multiplied by a fraction, the numerator of which is the employee's years of service as of the plan year, and the denominator of which is the employee's projected years of service as of normal retirement age. The greatest benefit that an employee could accrue in any plan year is four percent of average annual compensation (this is the case for an employee with 10 or fewer years of projected service at normal retirement age). Among employees with 33 or fewer years of projected service at normal retirement age, the lowest benefit that an employee could accrue in a plan year is 1.82 percent of average annual compensation (this is the case of an employee with 33 years of projected service at normal retirement age). Plan C fails to satisfy this paragraph (b)(4) because four percent is more than one third larger than 1.82 percent. See also § 1.401(a)(4)-9(c)(6) , Example 3.

Code of Federal Regulations

Example 4. Plan D provides a normal retirement benefit of 100 percent of average annual compensation, reduced by four percentage points for each year of service below 25 the employee has at normal retirement age. Plan D further provides that an employee's accrued benefit as of any plan year is equal to the employee's fractional rule benefit multiplied by a fraction, the numerator of which is the employee's years of service as of the plan year, and the denominator of which is the employee's projected years of service at normal retirement age. In the case of an employee who has five years of service as of the current plan year, and who is projected to have 10 years of service at normal retirement age, the employee's fractional rule benefit would be 40 percent of average annual compensation, and the employee's accrued benefit as of the current plan year would be 20 percent of average annual compensation (the fractional rule benefit multiplied by a fraction of five years over 10 years). Plan D satisfies this paragraph (b)(4).

Code of Federal Regulations

Example 5. The facts are the same as in Example 4, except that the normal retirement benefit is 125 percent of average annual compensation, reduced by five percentage points for each year of service below 25 that the employee has at normal retirement age. Plan D satisfies this paragraph (b)(4), even though an employee may accrue the maximum benefit allowed under section 415 (i.e., 100 percent of the participant's average compensation for the high three years of service) in less than 25 years.

Code of Federal Regulations

Example 6. The facts are the same as in Example 1, except that the plan determines each employee's accrued benefit by multiplying the employee's projected normal retirement benefit (rather than the fractional rule benefit) by the fraction described in Example 1. In determining an employee's projected normal retirement benefit, the plan defines each employee's average annual compensation as the average annual compensation the employee would have at normal retirement age if the employee's annual section 414(s) compensation in future plan years equaled the employee's plan year compensation for the prior plan year. Under these facts, Plan A does not satisfy paragraph (b)(4)(i)(B) of this section because the employee's accrued benefit is determined on the basis of a projected normal retirement benefit that is not the same as the employee's fractional rule benefit determined in accordance with § 1.411(b)-1(b)(3)(ii)(A) .

Code of Federal Regulations

Example 7. Plan E provides a normal retirement benefit of 50 percent of average annual compensation, with a pro rata reduction for employees with less than 30 years of service at normal retirement age. Plan E further provides that an employee's accrued benefit as of any plan year is equal to the employee's fractional rule benefit multiplied by a fraction, the numerator of which is the employee's years of service as of the plan year, and the denominator of which is the employee's projected years of service at normal retirement age. For purposes of determining this fraction, the plan limits the years of service taken into account for an employee to the number of years the employee has participated in the plan. However, all years of service (including years of service before the employee commenced participation in the plan) are taken into account in determining an employee's normal retirement benefit under the plan's benefit formula. Plan E fails to satisfy this paragraph (b)(4) because the years of service over which benefits accrue differ from the years of service used in applying the benefit formula under the plan. See paragraph (b)(2)(v) of this section.

Code of Federal Regulations

Example 8. (a) Plan F provides a normal retirement benefit equal to 2.0 percent of average annual compensation, plus 0.65 percent of average annual compensation above covered compensation, for each year of service up to 25. Plan F further provides that an employee's accrued benefit as of any plan year equals the sum of—
Code of Federal Regulations 116
(1) The employee's fractional rule benefit (determined as if the normal retirement benefit under the plan equaled 2.0 percent of average annual compensation for each year of service up to 25) multiplied by a fraction, the numerator of which is the employee's years of service as of the plan year and the denominator of which is the employee's projected years of service as of normal retirement age; plus (2) 0.65 percent of the employee's average annual compensation above covered compensation multiplied by the employee's years of service (up to 25) as of the current plan year. (b) Although Plan F satisfies the fractional accrual rule of section 411(b)(1)(C), the plan fails to satisfy this paragraph (b)(4) because the plan does not determine employees' accrued benefits in accordance with paragraph (b)(4)(i)(B) of this section.
(5) Safe harbor for insurance contract plans. A plan satisfies the safe harbor in this paragraph (b)(5) if it satisfies each of the following requirements:
(i) The plan must satisfy the accrual rule of section 411(b)(1)(F).
(ii) The plan must be an insurance contract plan within the meaning of section 412(i).
(iii) The benefit formula under the plan must be one that would satisfy the requirements of paragraph (b)(4) of this section if the stated normal retirement benefit under the formula accrued ratably over each employee's period of plan participation through normal retirement age in accordance with paragraph (b)(4)(i)(B) of this section. Thus, the benefit formula may not recognize years of service before an employee commenced participation in the plan because, otherwise, the definition of years of service for determining the normal retirement benefit would differ from the definition of years of service for determining the accrued benefit under paragraph (b)(4)(i)(B) of this section. See paragraph (b)(4)(ii), Example 7, of this section. Notwithstanding the foregoing, an insurance contract plan adopted and in effect on September 19, 1991, may continue to recognize years of service prior to an employee's participation in the plan for an employee who is a participant in the plan on that date to the extent provided by the benefit formula in the plan on such date.
(iv) The scheduled premium payments under an individual or group insurance contract used to fund an employee's normal retirement benefit must be level annual payments to normal retirement age. Thus, payments may not be scheduled to cease before normal retirement age.
(v) The premium payments for an employee who continues benefiting after normal retirement age must be equal to the amount necessary to fund additional benefits that accrue under the plan's benefit formula for the plan year.
(vi) Experience gains, dividends, forfeitures, and similar items must be used solely to reduce future premiums.
(vii) All benefits must be funded through contracts of the same series. Among other requirements, contracts of the same series must have cash values based on the same terms (including interest and mortality assumptions) and the same conversion rights. A plan does not fail to satisfy this requirement, however, if any change in the contract series or insurer applies on the same terms to all employees. But see § 1.401(a)(4)-5(a)(4), Example 12 (change in insurer considered a plan amendment subject to § 1.401(a)(4)-5(a) ).
(viii) If permitted disparity is taken into account, the normal retirement benefit stated under the plan's benefit formula must satisfy § 1.401(l)-3. For this purpose, the 0.75-percent factor in the maximum excess or offset allowance in § 1.401(l)-3(b)(2)(i) or (b)(3)(i), respectively, adjusted in accordance with § 1.401(l)-3(d)(9) and (e), is reduced by multiplying the factor by 0.80.
(6) Use of safe harbors not precluded by certain plan provisions— (i) In general. A plan does not fail to satisfy this paragraph (b) merely because the plan contains one or more of the provisions described in this paragraph (b)(6). Unless otherwise provided, any such provision must apply uniformly to all employees.
(ii) permitted disparity. The plan takes permitted disparity into account in a manner that satisfies section 401(l) in form. Thus, differences in employees' benefits under the plan attributable to uniform disparities permitted under § 1.401(l)-3 (including differences in disparities that are deemed uniform under § 1.401(l)-3(c)(2)) do not cause a plan to fail to satisfy this paragraph (b).
(iii) Different entry dates. The plan provides one or more entry dates during the plan year as permitted by section 410(a)(4).
(iv) Certain conditions on accruals. The plan provides that an employee's accrual for the plan year is less than a full accrual (including a zero accrual) because of a plan provision permitted by the year-of-participation rules of section 411(b)(4).
(v) Certain limits on accruals. The plan limits benefits otherwise provided under the benefit formula or accrual method to a maximum dollar amount or to a maximum percentage of average annual compensation (e.g., by limiting service taken into account in the benefit formula) or in accordance with section 401(a)(5)(D), applies the limits of section 415, or limits the dollar amount of compensation taken into account in determining benefits.
(vi) Dollar accrual per uniform unit of service. The plan determines accruals based on the same dollar amount for each uniform unit of service (not to exceed one week) performed by each employee with the same number of years of service under the plan during the plan year. The preceding sentence applies solely for purposes of the unit credit safe harbor in paragraph (b)(3) of this section.
(vii) Prior benefits accrued under a different formula. The plan determines benefits for years of service after a fresh-start date for all employees under a benefit formula and accrual method that differ from the benefit formula and accrual method previously used to determine benefit accruals for employees in a fresh-start group for years of service before the fresh-start date. This paragraph (b)(6)(vii) applies solely to plans that satisfy § 1.401(a)(4)-1 3(c) with respect to the fresh start.
(viii) Employee contributions. The plan is a contributory DB plan that would satisfy the requirements of paragraph (b) of this section if the plan's benefit formula provided benefits at employees' employer-provided benefit rates determined under § 1.401(a)(4)-6(b). This paragraph (b)(6)(viii) does not apply to a plan tested under paragraph (b)(4) or (b)(5) of this section unless the plan satisfies one of the methods in § 1.401(a)(4)-6 (b)(4) through (b)(6). A minimum benefit added to the plan solely to satisfy § 1.401(a)(4)-6(b)(3) is not taken into account in determining whether this paragraph (b)(6)(viii) is satisfied.
(ix) Certain subsidized optional forms. The plan provides a subsidized optional form of benefit that is available to fewer than substantially all employees because the optional form of benefit has been eliminated prospectively as provided in § 1.401(a)(4)-4(b)(3).
(x) Lower benefits for HCEs— (A) General rule. The benefits (including any subsidized optional form of benefit) provided to one or more HCEs under the plan are inherently less valuable to those HCEs (determined by applying the principles of § 1.401(a)(4)-4(d)(4)) than the benefits that would otherwise be provided to those HCEs if the plan satisfied this paragraph (b) (determined without regard to this paragraph (b)(6)(x)). These inherently less valuable benefits are deemed to satisfy this paragraph (b).
(B) Examples. The following examples illustrate the rules in this paragraph (b)(6)(x):

Code of Federal Regulations

Example 1. Plan A would satisfy this paragraph (b) (determined without regard to this paragraph (b)(6)(x)), except for the fact that it fails to satisfy the requirement of paragraph (b)(2)(iii) of this section (i.e., a subsidized optional form must be available to substantially all employees on similar terms). Each subsidized optional form in the plan is available to all the NHCEs on similar terms, but one of the subsidized optional forms of benefit is not available to any of the HCEs. Plan A satisfies this paragraph (b), because Plan A is a safe harbor plan with respect to the NHCEs and provides inherently less valuable benefits to the HCEs.

Code of Federal Regulations

Example 2. (a) Plan B would satisfy this paragraph (b) (determined without regard to this paragraph (b)(6)(x)), except for the fact that some employees are not being credited with years of service under the plan, but are continuing to accrue benefits as a result of compensation increases. These are employees who have been transferred from the employer that sponsors Plan B to another member of the controlled group whose employees are not covered by Plan B. For these employees, Plan B fails to satisfy the requirement of paragraph (b)(2)(v) of this section (i.e., each employee's benefit must accrue over the same years of service used in applying the benefit formula).
Code of Federal Regulations 118
(b) Plan B is restructured into two component plans under the provisions of § 1.401(a)(4)-9(c) . One component plan (Component Plan B1) consists of all NHCEs who are not being credited with years of service under the plan's benefit formula but are continuing to accrue benefits as a result of compensation increases, and the other component plan (Component Plan B2) consists of the balance of the employees. (c) Component Plan B1 satisfies this section and section 410(b), because it benefits only NHCEs. (d) Component Plan B2 is treated as satisfying this paragraph (b), because Plan B would satisfy this paragraph (b) (determined without regard to this paragraph (b)(6)(x)) with respect to the employees in Component Plan B2 but for the fact that it provides inherently less valuable benefits to some HCEs in that component plan (i.e., the employees who are credited only with compensation increases rather than both years of service and compensation increases). (e) Under § 1.401(a)(4)-9(c) , if Component Plan B2 satisfies section 410(b), then Plan B satisfies this section.
(xi) Multiple formulas— (A) General rule. The plan provides that an employee's benefit under the plan is the greater of the benefits determined under two or more formulas, or is the sum of the benefits determined under two or more formulas. This paragraph (b)(6)(xi) does not apply to a plan unless each of the formulas under the plan satisfies the requirements of paragraph (b)(6)(xi) (B) through (D) of this section.
(B) Sole formulas. The formulas must be the only formulas under the plan.
(C) Separate testing. Each of the formulas must separately satisfy the uniformity requirements of paragraph (b)(2) of this section and also separately satisfy one of the safe harbors in paragraphs (b)(3) through (b)(5) of this section. A formula that is available solely to some or all NHCEs is deemed to satisfy this paragraph (b)(6)(xi)(C).
(D) Availability— (1) General rule. All of the formulas must be available on the same terms to all employees.
(2) Formulas for NHCEs. A formula does not fail to be available on the same terms to all employees merely because the formula is not available to any HCEs, but is available to some or all NHCEs on the same terms as all of the other formulas in the plan.
(3) Top-heavy formulas. Rules parallel to those in § 1.401(a)(4)-2(b)(4)(vi)(D) (3) apply in the case of a plan that provides the greater of the benefits under two or more formulas, one of which is a top-heavy formula. For purposes of this paragraph (b)(6)(xi)(D)(3 ), a top-heavy formula is a formula that provides a benefit equal to the minimum benefit described in section 416(c)(1) (taking into account, if applicable, the modification in section 416(h)(2)(A)(ii)(I) ).
(E) Provisions may be applied more than once. The provisions of this paragraph (b)(6)(xi) may be applied more than once. See § 1.401(a)(4)-2(b)(4)(vi)(E) for an example of the application of these provisions more than once.
(F) Examples. The following examples illustrate the rules in this paragraph (b)(6)(xi):

Code of Federal Regulations

Example 1. Under Plan A, each employee's benefit equals the sum of the benefits determined under two formulas. The first formula provides one percent of average annual compensation per year of service. The second formula provides $10 per year of service. Plan A is eligible to apply the rules in this paragraph (b)(6)(xi).

Code of Federal Regulations

Example 2. Under Plan B, each employee's benefit equals the greater of the benefits determined under two formulas. The first formula provides $15 per year of service and is available to all employees who complete at least 500 hours of service during the plan year. The second formula provides 1.5 percent of average annual compensation per year of service and is available to all employees who complete at least 1,000 hours of service during the plan year. Plan B does not satisfy this paragraph (b)(6)(xi) because the two formulas are not available on the same terms to all employees.

Code of Federal Regulations

Example 3. Under Plan C, each employee's benefit equals the greater of the benefits determined under two formulas. The first formula provides $15 per year of service and is available to all employees who complete at least 1,000 hours of service during the plan year. The second formula provides the minimum benefit described in section 416(c)(1) and is available to all non-key employees who complete at least 1,000 hours of service during the plan year. Plan C does not satisfy the general rule in paragraph (b)(6)(xi)(D)(1) of this section because the two formulas are not available on the same terms to all employees (i.e., the second formula is only available to all non-key employees). Nonetheless, because the second formula is a top-heavy formula, the special availability rules for top-heavy formulas in paragraph (b)(6)(xi)(D)(3) of this section apply. Thus, the second formula does not fail to be available on the same terms as the first formula merely because the second formula is available solely to all non-key employees on the same terms. This is true even if the plan conditions the availability of the second formula on the plan's being top-heavy for the plan year.

Example 4. Under Plan D, each employee's benefit equals the greater of the benefits determined under two formulas. The first formula is available to all employees and provides a benefit equal to 1.5 percent of average annual compensation per year of service. The second formula is only available to NHCEs and provides a benefit equal to two percent of average annual compensation per year of service, minus two percent of the primary insurance amount per year of service. The amount of the offset is not limited to the maximum permitted offset under § 1.401(l)-3(b) . Under paragraph (b)(6)(xi)(D)(2) of this section, both formulas are treated as available to all employees on the same terms. Furthermore, even though the second formula does not satisfy any of the safe harbors in this paragraph (b), the formula is deemed to satisfy the separate testing requirement under paragraph (b)(6)(xi)(C) of this section, because the formula is available solely to some or all NHCEs.

Code of Federal Regulations

Example 5. Plan E is a unit credit plan that provides a benefit of one percent of average annual compensation per year of service to all employees. In 1994, the plan is amended to provide a benefit of two percent of average annual compensation per year of service after 1993, while continuing to provide a benefit of one percent of average annual compensation per year of service for all years of service before 1994. Thus, the plan's amended benefit formula provides a benefit equal to the sum of the benefits determined under two benefit formulas: one percent of average annual compensation per year of service, plus one percent of average annual compensation per year of service after 1993. Plan E satisfies this paragraph (b)(6)(xi).

Code of Federal Regulations

Example 6. The facts are the same as in Example 5, except that the plan amendment in 1994 decreases the benefit to 0.75 percent of average annual compensation per year of service after 1993, while retaining the one-percent formula for all years of service before 1994. Thus, the plan's amended benefit formula provides a benefit equal to the sum of the benefits determined under two benefit formulas: 0.75 percent of average annual compensation per year of service, plus 0.25 percent of average annual compensation per year of service before 1994. Under these facts, the second formula does not separately satisfy any of the safe harbors in this paragraph (b) because the years of service over which each employee's benefit accrues under the second formula (i.e., all years of service) are not the same years of service that are taken into account in applying the benefit formula under the plan to that employee (i.e., years of service before 1994). See paragraph (b)(2)(v) of this section. But see paragraph (b)(6)(vii) of this section and § 1.401(a)(4)-1 3, which provide rules under which Plan E, as amended, may be able to satisfy this paragraph (b).

Code of Federal Regulations

Example 7. Plan F provides a benefit to all employees of one percent of average annual compensation per year of service. Employee M was hired as the president of the employer in December 1994 and was not a HCE under section 414(q) during the 1994 calendar plan year. In 1994, Plan F is amended to provide a benefit that is the greater of the benefit determined under the pre-existing formula in the plan and a new formula that is available solely to some NHCEs (including Employee M). The new formula does not satisfy the uniformity requirements of paragraph (b)(2) of this section, because it provides a different benefit for some NHCEs than for other NHCEs. As a result of this change, Employee M receives a higher accrual in 1994 than the NHCEs who are not eligible for the new formula. In 1995, when Employee M first becomes a HCE, the second formula no longer applies to Employee M. It would be inconsistent with the purpose of preventing discrimination in favor of HCEs for Plan F to use the special rule for a formula that is available solely to some or all NHCEs to satisfy the separate testing requirement of paragraph (b)(6)(xi)(C) of this section for the 1994 calendar plan year. See § 1.401(a)(4)-1(c)(2) .
(c) General test for nondiscrimination in amount of benefits— (1) General rule. The employer-provided benefits under a defined benefit plan are nondiscriminatory in amount for a plan year if each rate group under the plan satisfies section 410(b). For purposes of this paragraph (c)(1), a rate group exists under a plan for each HCE and consists of the HCE and all other employees (both HCEs and NHCEs) who have a normal accrual rate greater than or equal to the HCE's normal accrual rate, and who also have a most valuable
