1.411(b)(5)-1—Reduction in rate of benefit accrual under a defined benefit plan.

(a) In general— (1) Organization of regulation. This section sets forth certain rules for determining whether a reduction occurs in the rate of benefit accrual under a defined benefit plan because of the attainment of any age for purposes of section 411(b)(1)(H)(i). Paragraph (b) of this section describes safe harbors for certain plan designs (including statutory hybrid plans) that are deemed to satisfy the age discrimination rules under section 411(b)(1)(H). Paragraph (c) of this section describes rules relating to statutory hybrid plan conversion amendments. Paragraph (d) of this section describes rules restricting interest credits (or equivalent amounts) under a statutory hybrid plan to a market rate of return. Paragraph (e) of this section contains additional rules related to market rates of return. Paragraph (f) of this section contains effective/applicability dates.
(2) Definitions. The definitions of accumulated benefit, lump sum-based benefit formula, statutory hybrid benefit formula, statutory hybrid plan, and variable annuity benefit formula in § 1.411(a)(13)-1(d) apply for purposes of this section.
(b) Safe harbors for certain plan designs— (1) Accumulated benefit testing— Pursuant to section 411(b)(5)(A), and subject to paragraph (b)(1)(ii) of this section, a plan is not treated as failing to meet the requirements of section 411(b)(1)(H)(i) with respect to an individual who is or could be a participant if, as of any date, the accumulated benefit of the individual would not be less than the accumulated benefit of any similarly situated, younger individual who is or could be a participant. Thus, this test involves a comparison of the accumulated benefit of an individual who is or could be a participant in the plan with the accumulated benefit of each similarly situated, younger individual who is or could be a participant in the plan. See paragraph (b)(5) of this section for rules regarding whether a younger individual who is or could be a participant is similarly situated to a participant. The comparison described in this paragraph (b)(1)(i) is based on any one of the following benefit measures, each of which is referred to as a safe-harbor formula measure:
(A) The annuity payable at normal retirement age (or current age, if later) if the accumulated benefit of the participant under the terms of the plan is an annuity payable at normal retirement age (or current age, if later).
(B) The current balance of a hypothetical account maintained for the participant if the accumulated benefit of the participant under the terms of the plan is a balance of a hypothetical account.
(C) The current value of an accumulated percentage of the participant's final average compensation if the accumulated benefit of the participant under the terms of the plan is an accumulated percentage of final average compensation.
(ii) Benefit formulas for comparison— (A) In general. Except as provided in paragraphs (b)(1)(ii)(B), (C), and (D) of this section, the safe harbor provided by section 411(b)(5)(A) and paragraph (b)(1)(i) of this section is available with respect to an individual only if the individual's accumulated benefit under the plan is expressed in terms of only one safe-harbor formula measure and no similarly situated, younger individual who is or could be a participant has an accumulated benefit that is expressed in terms of any measure other than that same safe-harbor formula measure. Thus, for example, if a plan provides that the accumulated benefit of participants who are age 55 or over is expressed under the terms of the plan as a life annuity payable at normal retirement age (or current age, if later) as described in paragraph (b)(1)(i)(A) of this section and the plan provides that the accumulated benefit of participants who are younger than age 55 is expressed as the current balance of a hypothetical account as described in paragraph (b)(1)(i)(B) of this section, then the safe harbor described in section 411(b)(5)(A) and paragraph (b)(1)(i) of this section does not apply to individuals who are or could be participants who are age 55 or over.
(B) Sum-of benefit formulas. If a plan provides that a participant's accumulated benefit is expressed as the sum of benefits determined in terms of two or more benefit formulas, each of which is expressed in terms of a different safe-harbor formula measure, then the plan is deemed to satisfy paragraph (b)(1)(i) of this section with respect to an individual who is or could be a participant, provided that the plan satisfies the comparison described in paragraph (b)(1)(i) of this section separately for benefits determined in terms of each safe-harbor formula measure and no accumulated benefit of a similarly situated, younger individual who is or could be a participant is expressed other than as—
(1) The sum of benefits under two or more benefit formulas, each of which is expressed in terms of one of those same safe-harbor formula measures as is used for the participant's “sum-of” benefit;
(2) The greater of benefits under two or more benefit formulas, each of which is expressed in terms of any one of those same safe-harbor formula measures;
(3) The choice of benefits under two or more benefit formulas, each of which is expressed in terms of any one of those same safe-harbor formula measures; or
(4) A benefit that is determined in terms of only one of those same safe-harbor formula measures.
(C) Greater-of benefit formulas. If a plan provides that a participant's accumulated benefit is expressed as the greater of benefits under two or more benefit formulas, each of which is determined in terms of a different safe-harbor formula measure, then the plan is deemed to satisfy paragraph (b)(1)(i) of this section with respect to an individual who is or could be a participant, provided that the plan satisfies the comparison described in paragraph (b)(1)(i) of this section separately for benefits determined in terms of each safe-harbor formula measure and no accumulated benefit of a similarly situated, younger individual who is or could be a participant is expressed other than as—
(1) The greater of benefits determined under two or more benefit formulas, each of which is expressed in terms of one of those same safe-harbor formula measures as is used for the participant's “greater-of” benefit;
(2) The choice of benefits determined under two or more benefit formulas, each of which is expressed in terms of one of those same safe-harbor formula measures; or
(3) A benefit that is determined in terms of only one of those same safe-harbor formula measures.
(D) Choice-of benefit formulas. If a plan provides that a participant's accumulated benefit is determined pursuant to a choice by the participant between benefits determined in terms of two or more different safe-harbor formula measures, then the plan is deemed to satisfy paragraph (b)(1)(i) of this section with respect to an individual who is or could be a participant, provided that the plan satisfies the comparison described in paragraph (b)(1)(i) of this section separately for benefits determined in terms of each safe-harbor formula measure and no accumulated benefit of a similarly situated, younger individual who is or could be a participant is expressed other than as—
(1) The choice of benefits determined under two or more benefit formulas, each of which is expressed in terms of one of those same safe-harbor formula measures as is used for the participant's “choice-of” benefit; or
(2) A benefit that is determined in terms of only one of those same safe-harbor formula measures.
(iii) Disregard of certain subsidized benefits. For purposes of paragraph (b)(1)(i) of this section, any subsidized portion of any early retirement benefit that is included in a participant's accumulated benefit is disregarded. For this purpose, the subsidized portion of an early retirement benefit is the retirement-type subsidy within the meaning of § 1.411(d)-3(g)(6) that is contingent on a participant's severance from employment and commencement of benefits before normal retirement age.
(iv) Examples. The provisions of this paragraph (b)(1) are illustrated by the following examples:

Code of Federal Regulations

Example 1. (i) Facts relating to formulas described in paragraph (b)(1)(i)(A) of this section. Employer X maintains a defined benefit plan that provides a straight life annuity payable commencing at normal retirement age (which is age 65) equal to 1 percent of the participant's highest 3 consecutive years' compensation times years of service and provides for suspension of benefits as permitted under section 411(a)(3)(B). In the case of a participant whose service continues after normal retirement age, the amount payable is the greater of (i) the benefit payable at normal retirement age, and for each year thereafter, actuarially increased to account for delayed commencement, and (ii) the retirement benefit determined under the formula at the date the employee's service ceases (calculated by including years of service and increases in compensation after normal retirement age). (ii) Conclusion. Under these facts, the plan formula is a formula described in paragraph (b)(1)(i)(A) of this section. The formula is not a statutory hybrid benefit formula merely because the plan formula includes a benefit that is based on the participant's benefit at normal retirement age (and each year thereafter) that is actuarially increased for commencement after attainment of normal retirement age. In addition, the plan formula would satisfy the comparison under paragraph (b)(1)(i) of this section for each individual who is or could be a participant because, as of any date (including any date after normal retirement age), the accumulated benefit of the individual would not be less than the accumulated benefit of any similarly situated, younger individual who is or could be a participant.

Code of Federal Regulations

Example 2. (i) Facts relating to formulas described in paragraph (b)(1)(i)(B) of this section. Employer Y maintains a defined benefit plan that expresses each participant's accumulated benefit as the balance of a hypothetical account. Under the formula, the hypothetical account balance of each participant is credited monthly with interest at a specified rate and the hypothetical account balance of each employee who is a participant is also credited with a pay credit under the plan equal to 7 percent of the participant's compensation for the month. (ii) Conclusion. The plan formula is a lump sum-based benefit formula described in paragraph (b)(1)(i)(B) of this section and the formula would satisfy the comparison under paragraph (b)(1)(i) of this section for each individual who is or could be a participant because, as of any date, the hypothetical account balance of the individual would not be less than the hypothetical account balance of any similarly situated, younger individual who is or could be a participant.

Code of Federal Regulations

Example 3. (i) Facts where plan suspends interest credits after normal retirement age. The facts are the same as in Example 2 except that the plan provides for suspension of benefits as permitted under section 411(a)(3)(B). Pursuant to the plan's suspension of benefits provision, the plan provides for interest credits to cease during service after normal retirement age or for the amount of the interest credits during this service to be reduced to reflect principal credits credited. (ii) Conclusion. The plan does not satisfy the safe harbor in paragraph (b)(1)(i) of this section. Applying the rule of paragraph (b)(1)(i) of this section, the plan formula would fail to satisfy the safe harbor comparison under paragraph (b)(1)(i) of this section with respect to an individual whose benefits have been suspended because, as of any date after attainment of normal retirement age, the hypothetical account balance of this individual would be less than the hypothetical account balance of one or more similarly situated individuals who have not attained normal retirement age.

Code of Federal Regulations

Example 4. (i) Facts providing greater-of benefits as described in paragraph (b)(1)(ii)(C) of this section. Employer Z sponsors a defined benefit plan that provides an accumulated benefit expressed as a straight life annuity commencing at the plan's normal retirement age (age 65), based on a percentage of average annual compensation times the participant's years of service. On November 2, 2011, the plan is amended effective as of January 1, 2012, to provide participants who have attained age 55 by January 1, 2012, with a benefit that is the greater of the benefit under the average annual compensation formula and a benefit that is based on the balance of a hypothetical account, which provides for annual pay credits of a specified percentage of the participant's compensation and annual interest credits based on the third segment rate. (ii) Conclusion where plan provides greater-of benefits to older participants. The plan satisfies the safe harbor of paragraph (b)(1)(i) of this section with respect to all individuals who are or could be participants. Pursuant to the rules of paragraph (b)(1)(ii)(C) of this section, the plan satisfies the safe harbor with respect to individuals who have attained age 55 by January 1, 2012, because (A) with respect to the benefit described in paragraph (b)(1)(i)(A) of this section (the benefit based on average annual compensation, disregarding the benefit based on the balance of a hypothetical account), the accumulated benefit for any individual who is or could be a participant and who is at least age 55 on January 1, 2012, would in no event be less than the accumulated benefit for a similarly situated, younger individual who is or could be participant and who has not yet attained age 55 by January 1, 2012, (B) with respect to the benefit described in paragraph (b)(1)(i)(B) of this section (the benefit based on the balance of a hypothetical account, disregarding the benefit based on average annual compensation), the accumulated benefit for any individual who is or could be a participant and who is at least age 55 on January 1, 2012, would in no event be less than the accumulated benefit for a similarly situated, younger individual who is or could be a participant and who has not yet attained age 55 by January 1, 2012, and (C) the benefit of any individual who is or could be a participant who has not yet attained age 55 by January 1, 2012, is only expressed as an annuity payable at normal retirement age as described in paragraph (b)(1)(i)(A) of this section, and this safe-harbor formula measure applies also to participants who have attained age 55 by January 1, 2012. Furthermore, the plan satisfies the safe harbor with respect to individuals who have not yet attained age 55 by January 1, 2012, because the benefit of these individuals satisfies the general rule of paragraph (b)(1)(ii)(A) of this section.
Code of Federal Regulations 808
(iii) Conclusion where plan provides greater-of benefits only to younger participants. If, instead of the facts in paragraph (i) of this Example 4, the plan had been amended to provide only participants who have not yet attained age 55 by January 1, 2012, with a benefit that is the greater of the benefit under the average annual compensation formula and a benefit that is based on the balance of a hypothetical account, then the safe harbor would not be satisfied with respect to individuals who have attained age 55 by January 1, 2012.Under paragraph (b)(1)(ii)(A) of this section, except as provided in paragraphs (b)(1)(ii)(B), (C), and (D) of this section, the safe harbor of paragraph (b)(1)(i) of this section is available only with respect to individuals over age 55, whose benefit is expressed in terms of only one safe-harbor formula measure, if no similarly situated, younger individual has an accumulated benefit that is expressed in terms of any measure other than that same safe-harbor formula measure. This is not the case under these facts. The greater-of rule of paragraph (b)(1)(ii)(C) of this section would not apply to individuals who have attained age 55 because the accumulated benefits of these individuals is not equal to the greater of benefits under two or more benefit formulas.

Code of Federal Regulations

Example 5. (i) Facts where plan provides choice-of benefits to older participants. The facts are the same as in paragraph (i) of Example 4, except that for service after December 31, 2011, the amendment permits participants who have attained age 55 by January 1, 2012, to choose between benefits under the average annual compensation benefit formula or benefits under the hypothetical account balance formula (but, if a participant chooses the hypothetical account balance formula, his or her benefit under the plan is in no event to be less than the benefit determined under the average annual compensation benefit formula for service before January 1, 2012), while other participants receive benefits solely under the hypothetical account balance formula (but individuals who are participants on December 31, 2011, are in no event to receive less than the benefit determined under the average annual compensation benefit formula for service before January 1, 2012). (ii) Conclusion where plan provides choice to older participants. The plan satisfies the safe harbor with respect to all individuals who are or could be participants. Pursuant to the rule of paragraph (b)(1)(ii)(D) of this section, the plan satisfies the safe harbor of paragraph (b)(1)(i) of this section with respect to individuals who have attained age 55 by January 1, 2012, and, pursuant to the rule of paragraph (b)(1)(ii)(A), the plan satisfies the safe harbor with respect to individuals who have not yet attained 55 by January 1, 2012. (iii) Conclusion where plan provides choice-of benefits to older workers and greater-of benefits to younger participants. If, in addition to the facts in paragraph (i) of this Example 5, the plan were also to provide participants who had not yet attained age 55 by January 1, 2012, the greater of the benefits under the average annual compensation benefit formula or the benefits under the hypothetical account balance formula, then pursuant to the rules of paragraph (b)(1)(ii)(A) and (D) of this section, the safe harbor would not be satisfied with respect to participants who have attained age 55 by January 1, 2012.
(2) Indexed benefits— (i) In general. Except as provided in paragraph (b)(2)(iii) of this section, pursuant to section 411(b)(5)(E) and this paragraph (b)(2)(i), a defined benefit plan is not treated as failing to meet the requirements of section 411(b)(1)(H) with respect to a participant solely because a benefit formula (other than a lump sum-based benefit formula) under the plan provides for the periodic adjustment of the participant's accrued benefit under the plan by means of the application of a recognized index or methodology. For purpose of the preceding sentence, a rate that does not exceed a market rate of return, as defined in paragraph (d) of this section, is deemed to be a recognized index or methodology. However, such a plan must satisfy the qualification requirements otherwise applicable to statutory hybrid plans, including the requirements of § 1.411(a)(13)-1(c) (relating to minimum vesting standards) and paragraph (c) of this section (relating to plan conversion amendments).
(ii) Similarly situated participant test. Paragraph (b)(2)(i) of this section does not apply unless the aggregate adjustments made to a participant's accrued benefit under the plan (determined as a percentage of the unadjusted accrued benefit) in a period would not be less than the aggregate adjustments for any similarly situated, younger participant. This test requires a comparison, for each period, of the aggregate adjustments for each individual who is or could be a participant in the plan for the period with the aggregate adjustments of each other similarly situated, younger individual who is or could be a participant in the plan for that period. See paragraph (b)(5) of this section for rules regarding whether each younger individual who is or could be a participant is similarly situated to a participant.
(iii) Protection against loss— (A) In general. Paragraph (b)(2)(i) of this section does not apply unless the plan satisfies section 411(b)(5)(E)(ii) and paragraph (d)(2) of this section (relating to preservation of capital).
(B) Exception for variable annuity benefit formulas. The requirement to satisfy section 411(b)(5)(B)(i)(II), as set forth in paragraph (d)(2) of this section, as well as section 411(b)(5)(E)(ii), as set forth in this paragraph (b)(2)(iii), does not apply in the case of a benefit provided under a variable annuity benefit formula as defined in § 1.411(a)(13)-1(d)(6).
(3) Certain offsets permitted. A plan is not treated as failing to meet the requirements of section 411(b)(1)(H) solely because the plan provides offsets against benefits under the plan to the extent the offsets are allowable in applying the requirements of section 401(a) and the applicable requirements of the Employee Retirement Income Security Act of 1974, Public Law 93-406 (88 Stat. 829 (1974)), and the Age Discrimination in Employment Act of 1967, Public Law 90-202 (81 Stat. 602 (1967)).
(4) Permitted disparities in plan contributions or benefits. A plan is not treated as failing to meet the requirements of section 411(b)(1)(H) solely because the plan provides a disparity in contributions or benefits with respect to which the requirements of section 401(l) are met.
(5) Definition of similarly situated. For purposes of paragraphs (b)(1) and (b)(2) of this section, an individual is similarly situated to another individual if the individual is identical to that other individual in every respect that is relevant in determining a participant's benefit under the plan (including period of service, compensation, position, date of hire, work history, and any other respect) except for age. In determining whether an individual is similarly situated to another individual, any characteristic that is relevant for determining benefits under the plan and that is based directly or indirectly on age is disregarded. For example, if a particular benefit formula applies to a participant on account of the participant's age, an individual to whom the benefit formula does not apply and who is identical to the participant in all other respects is similarly situated to the participant. By contrast, an individual is not similarly situated to a participant if a different benefit formula applies to the individual and the application of the different formula is not based directly or indirectly on age.
(c) Special rules for plan conversion amendments— (1) In general. Pursuant to section 411(b)(5)(B)(ii), (iii), and (iv), if there is a conversion amendment within the meaning of paragraph (c)(4) of this section with respect to a defined benefit plan, then the plan is treated as failing to meet the requirements of section 411(b)(1)(H) unless the plan, after the amendment, satisfies the requirements of paragraph (c)(2) of this section.
(2) Separate calculation of post-conversion benefit— (i) In general. A statutory hybrid plan satisfies the requirements of this paragraph (c)(2) if the plan provides that, in the case of an individual who was a participant in the plan immediately before the date of adoption of the conversion amendment, the participant's benefit at any subsequent annuity starting date is not less than the sum of—
(A) The participant's section 411(d)(6) protected benefit (as defined in § 1.411(d)-3(g)(14)) with respect to service before the effective date of the conversion amendment, determined under the terms of the plan as in effect immediately before the effective date of the conversion amendment; and
(B) The participant's section 411(d)(6) protected benefit with respect to service on and after the effective date of the conversion amendment, determined under the terms of the plan as in effect after the effective date of the conversion amendment.
(ii) Rules of application. For purposes of this paragraph (c)(2), except as provided in paragraph (c)(3) of this section, the benefits under paragraphs (c)(2)(i)(A) and (c)(2)(i)(B) of this section must each be determined in the same manner as if they were provided under separate plans that are independent of each other (for example, without any benefit offsets), and, except to the extent permitted under § 1.411(d)-3 or § 1.411(d)-4 (or other applicable law), each optional form of payment provided under the terms of the plan with respect to a participant's section 411(d)(6) protected benefit as in effect before the conversion amendment must be available thereafter to the extent of the plan's benefits for service prior to the effective date of the conversion amendment.
(3) Establishment of opening hypothetical account balance or opening accumulated percentage— (i) In general. Provided that the requirements of paragraph (c)(3)(ii) or (c)(3)(iii) of this section are satisfied, a statutory hybrid plan under which an opening hypothetical account balance or opening accumulated percentage of the participant's final average compensation is established as of the effective date of the conversion amendment does not fail to satisfy the requirements of paragraph (c)(2) of this section merely because benefits attributable to that opening hypothetical account balance or opening accumulated percentage (that is, benefits that are not described in paragraph (c)(2)(i)(B) of this section) are substituted for benefits described in paragraph (c)(2)(i)(A) of this section.
(ii) Comparison of benefits at annuity starting date— (A) Testing requirement. The requirements of this paragraph (c)(3)(ii) are satisfied with respect to an optional form of benefit payable at an annuity starting date only if the plan provides that the amount of the benefit payable in that optional form under the lump sum-based benefit formula that is attributable to the opening hypothetical account balance or opening accumulated percentage as described in paragraph (c)(3)(i) of this section is not less than the benefit under the comparable optional form of benefit under paragraph (c)(2)(i)(A) of this section. To satisfy this requirement, if the benefit under the optional form attributable to the opening hypothetical account balance or opening accumulated percentage is less than the benefit under the comparable optional form of benefit described in paragraph (c)(2)(i)(A) of this section, then the benefit attributable to the opening hypothetical account balance or opening accumulated percentage must be increased to the extent necessary to provide the minimum benefit described in this paragraph (c)(3)(ii). Thus, if a plan is using the option under this paragraph (c)(3)(ii) to satisfy paragraph (c)(2) of this section with respect to a participant, the participant must receive a benefit equal to not less than the sum of—
(1) The benefit described in paragraph (c)(2)(i)(B) of this section; and
(2) The greater of—
(i) The benefit attributable to the opening hypothetical account balance or attributable to the opening accumulated percentage of the participant's final average compensation as described in this paragraph (c)(3)(ii); or
(ii) The benefit described in paragraph (c)(2)(i)(A) of this section.
(B) Comparable optional form of benefit. If there was an optional form of benefit within the same generalized optional form of benefit (within the meaning of § 1.411(d)-3(g)(8)) that would have been available to the participant at that annuity starting date under the terms of the plan as in effect immediately before the effective date of the conversion amendment, then that optional form of benefit is the comparable optional form of benefit.
(C) Special rule for new post-conversion optional forms of benefit. If an optional form of benefit is available on the annuity starting date with respect to the benefit attributable to the opening hypothetical account balance or opening accumulated percentage, but no optional form within the same generalized optional form of benefit (within the meaning of § 1.411(d)-3(g)(8)) was available at that annuity starting date under the terms of the plan as in effect immediately prior to the effective date of the conversion amendment, then, for purposes of this paragraph (c)(3)(ii), the plan is treated as if such an optional form of benefit were available immediately prior to the effective date of the conversion amendment for purposes of this paragraph (c)(3)(ii). Thus, for example, if a single-sum optional form of payment is not available under the plan terms applicable to the accrued benefit described in paragraph (c)(2)(i)(A) of this section, but a single-sum optional form of payment is available with respect to the benefit attributable to the opening hypothetical account balance or opening accumulated percentage as of the annuity starting date, then, for purposes of this paragraph (c)(3)(ii), the plan is treated as if a single sum (which satisfies the requirements of section 417(e)(3)) were available under the terms of the plan as in effect immediately prior to the effective date of the conversion amendment.
(iii) Comparison of benefits at effective date of conversion amendment. [Reserved]
(4) Conversion amendment— (i) In general. An amendment is a conversion amendment that is subject to the requirements of this paragraph (c) with respect to a participant if—
(A) The amendment reduces or eliminates the benefits that, but for the amendment, the participant would have accrued after the effective date of the amendment under a benefit formula that is not a statutory hybrid benefit formula (and under which the participant was accruing benefits prior to the amendment); and
(B) After the effective date of the amendment, all or a portion of the participant's benefit accruals under the plan are determined under a statutory hybrid benefit formula.
(ii) Rules of application— (A) In general. Paragraphs (c)(4)(iii), (iv), and (v) of this section describe special rules that treat certain arrangements as conversion amendments. The rules described in those paragraphs apply both separately and in combination. Thus, for example, in an acquisition described in § 1.410(b)-2(f), if the buyer adopts an amendment under which a participant's benefits under the seller's plan that is not a statutory hybrid plan are coordinated with a separate plan of the buyer that is a statutory hybrid plan, such as through an offset of the participant's benefit under the buyer's plan by the participant's benefit under the seller's plan, the seller and buyer are treated as a single employer under paragraph (c)(4)(iv) of this section and they are treated as having adopted a conversion amendment under paragraph (c)(4)(iii) of this section. However, pursuant to paragraph (c)(4)(iii) of this section, if there is no coordination between the two plans, there is no conversion amendment.
(B) Covered amendments. Only amendments that eliminate or reduce accrued benefits described in section 411(a)(7), or a retirement-type subsidy described in section 411(d)(6)(B)(i), that would otherwise accrue as a result of future service are treated as amendments described in paragraph (c)(4)(i)(A) of this section.
(C) Operation of plan terms treated as covered amendment. If, under the terms of a plan, a change in the conditions of a participant's employment results in a reduction of the participant's benefits that would have accrued in the future under a benefit formula that is not a statutory hybrid benefit formula, the plan is treated for purposes of this paragraph (c)(4) as if such plan terms constitute an amendment that reduces the participant's benefits that would have accrued after the effective date of the change under a benefit formula that is not a statutory hybrid benefit formula. Thus, for example, if a participant transfers from an operating division that is covered by a non-statutory hybrid benefit formula to an operating division that is covered by a statutory hybrid benefit formula, there has been a conversion amendment and the effective date of the conversion amendment is the date of the transfer. For purposes of applying the effective date rule of paragraph (f)(1)(ii) of this section, the date that the relevant plan terms were adopted is treated as the adoption date of the amendment.
(iii) Multiple plans. An employer is treated as having adopted a conversion amendment if the employer adopts an amendment under which a participant's benefits under a plan that is not a statutory hybrid plan are coordinated with a separate plan that is a statutory hybrid plan, such as through a reduction (offset) of the benefit under the plan that is not a statutory hybrid plan.
(iv) Multiple employers. If the employer of an employee changes as a result of a transaction described in § 1.410(b)-2(f), then the two employers are treated as a single employer for purposes of this paragraph (c)(4).
(v) Multiple amendments— (A) In general— (1) General rule. For purposes of this paragraph (c)(4), a conversion amendment includes multiple amendments that result in a conversion amendment even if the amendments are not conversion amendments individually. For example, an employer is treated as having adopted a conversion amendment if the employer first adopts an amendment described in paragraph (c)(4)(i)(A) of this section and, at a later date, adopts an amendment that adds a benefit under a statutory hybrid benefit formula as described in paragraph (c)(4)(i)(B) of this section, if they are consolidated under paragraph (c)(4)(v)(A)(2) of this section.
(2) Delay between plan amendments. In determining whether a conversion amendment has been adopted, an amendment to provide a benefit under a statutory hybrid benefit formula is consolidated with a prior amendment to reduce non-statutory hybrid benefit formula benefits if the amendment providing benefits under a statutory hybrid benefit formula is adopted within three years after adoption of the amendment reducing non-statutory hybrid benefit formula benefits. Thus, the later adoption of the statutory hybrid benefit formula will cause the earlier amendment to be treated as part of a conversion amendment. In the case of an amendment to provide a benefit under a statutory hybrid benefit formula that is adopted more than three years after adoption of an amendment to reduce benefits under a non-statutory hybrid benefit formula, there is a presumption that the amendments are not consolidated unless the facts and circumstances indicate that adoption of the amendment to provide a benefit under a statutory hybrid benefit formula was intended at the time of reduction in the non-statutory hybrid benefit formula.
(B) Multiple conversion amendments. If an employer adopts multiple amendments reducing benefits described in paragraph (c)(4)(i)(A) of this section, each amendment is treated as a separate conversion amendment, provided that paragraph (c)(4)(i)(B) of this section is applicable at the time of the amendment (taking into account the rules of this paragraph (c)(4)).
(vi) Effective date of a conversion amendment. The effective date of a conversion amendment is, with respect to a participant, the date as of which the reduction of the participant's benefits described in paragraph (c)(4)(i)(A) of this section occurs. In accordance with section 411(d)(6), the date of a reduction of those benefits cannot be earlier than the date of adoption of the conversion amendment.
(5) Examples. The following examples illustrate the application of this paragraph (c):

Code of Federal Regulations

Example 1. (i) Facts where plan does not establish opening hypothetical account balance for participants and participant elects life annuity at normal retirement age. Employer N sponsors Plan E, a defined benefit plan that provides an accumulated benefit, payable as a straight life annuity commencing at age 65 (which is Plan E's normal retirement age), based on a percentage of highest average compensation times the participant's years of service. Plan E permits any participant who has had a severance from employment to elect payment in the following optional forms of benefit (with spousal consent if applicable), with any payment not made in a straight life annuity converted to an equivalent form based on reasonable actuarial assumptions: A straight life annuity; and a 50 percent, 75 percent, or 100 percent joint and survivor annuity. The payment of benefits may commence at any time after attainment of age 55, with an actuarial reduction if the commencement is before normal retirement age. In addition, the plan offers a single-sum payment after attainment of age 55 equal to the present value of the normal retirement benefit using the applicable interest rate and mortality table under section 417(e)(3) in effect under the terms of the plan on the annuity starting date.

(ii) Facts relating to the conversion amendment. On January 1, 2012, Plan E is amended to eliminate future accruals under the highest average compensation benefit formula and to base future benefit accruals under a hypothetical account balance formula. For service on or after January 1, 2012, each participant's hypothetical account balance is credited monthly with a pay credit equal to a specified percentage of the participant's compensation during the month and also with interest based on the third segment rate described in section 430(h)(2)(C)(iii). With respect to benefits under the hypothetical account balance attributable to service on and after January 1, 2012, a participant is permitted to elect (with spousal consent if applicable) payment in the same generalized optional forms of benefit (even though different actuarial factors apply) as under the terms of the plan in effect before January 1, 2012, and also as a single-sum distribution. The plan provides for the benefit attributable to service before January 1, 2012, to be determined under the terms of the plan as in effect immediately before the effective date of the amendment, and the benefit attributable to service on and after January 1, 2012, to be determined separately, under the terms of the plan as in effect after the effective date of the amendment, with neither benefit offsetting the other in any manner. Thus, each participant's benefit is equal to the sum of the benefit attributable to service before January 1, 2012 (to be determined under the terms of the plan as in effect immediately before the effective date of the amendment), plus the benefit attributable to the participant's hypothetical account balance. (iii) Facts relating to an affected participant. Participant A is age 62 on January 1, 2012. On December 31, 2011, A's benefit for years of service before January 1, 2012, payable as a straight life annuity commencing at A's normal retirement age (age 65), which is January 1, 2015, is $1,000 per month. On January 1, 2015, when Participant A has a severance from employment, the then-current hypothetical account balance, with pay credits and interest from January 1, 2012, to January 1, 2015, is $11,000. Using the conversion factors applicable under the plan on January 1, 2015, that balance is equivalent to a straight life annuity of $100 per month commencing on January 1, 2015. This benefit is in addition to the benefit attributable to service before January 1, 2012. Participant A elects (with spousal consent) a straight life annuity of $1,100 per month commencing January 1, 2015. (iv) Conclusion. Participant A's benefit satisfies the requirements of paragraph (c) of this section because Participant A's benefit is not less than the sum of Participant A's section 411(d)(6) protected benefit (as defined in § 1.411(d)-3(g)(14) ) with respect to service before the effective date of the conversion amendment, determined under the terms of the plan as in effect immediately before the effective date of the amendment, and Participant A's section 411(d)(6) protected benefit with respect to service on and after the effective date of the conversion amendment, determined under the terms of the plan as in effect after the effective date of the amendment.

Example 2. (i) Facts involving plan's establishment of opening hypothetical account balance and payment of pre-conversion accumulated benefit in life annuity at normal retirement age. Except as indicated in this Example 2, the facts are the same as the facts under paragraph (i) of Example 1. (ii) Facts relating to the conversion amendment. On January 1, 2012, Plan E is amended to eliminate future accruals under the highest average compensation benefit formula and to provide future benefit accruals under a hypothetical account balance formula. An opening hypothetical account balance is established for each participant, and, under the plan's terms, that balance is equal to the present value of the participant's accumulated benefit on December 31, 2011 (payable as a straight life annuity at normal retirement age or immediately, if later), using the applicable interest rate and applicable mortality table under section 417(e)(3) on January 1, 2012. Under Plan E, the account based on this opening hypothetical account balance is maintained as a separate account from the account for accruals on or after January 1, 2012. The hypothetical account balance maintained for each participant for accruals on or after January 1, 2012, is credited monthly with a pay credit equal to a specified percentage of the participant's compensation during the month. A participant's hypothetical account balance (including both of the separate accounts) is credited monthly with interest based on the third segment rate described in section 430(h)(2)(C)(iii). (iii) Facts relating to optional forms of benefit. Following severance from employment and attainment of age 55, a participant is permitted to elect (with spousal consent, if applicable) payment in the same generalized optional forms of benefit as under the plan in effect prior to January 1, 2012, with the amount payable calculated based on the hypothetical account balance on the annuity starting date and the applicable interest rate and applicable mortality table on the annuity starting date. The single-sum distribution is equal to the hypothetical account balance.
Code of Federal Regulations 814
(iv) Facts relating to conversion protection. The plan provides that, as of a participant's annuity starting date, the plan will determine whether the benefit attributable to the opening hypothetical account balance payable in the particular optional form of benefit selected is equal to or greater than the benefit accrued under the plan through the date of conversion and payable in the same generalized optional form of benefit with the same annuity starting date. If the benefit attributable to the opening hypothetical account balance is equal to or greater than the pre-conversion benefit, the plan provides that such benefit is paid in lieu of the pre-conversion benefit, together with the benefit attributable to post-conversion pay-based principal credits. If the benefit attributable to the opening hypothetical account balance is less than the pre-conversion benefit, the plan provides that such benefit is increased sufficiently to provide the pre-conversion benefit, together with the benefit attributable to post-conversion pay-based principal credits. (v) Facts relating to an affected participant. On January 1, 2012, the opening hypothetical account balance established for Participant A is $80,000, which is the present value of Participant A's straight life annuity of $1,000 per month commencing at January 1, 2015, using the applicable interest rate and applicable mortality table under section 417(e)(3) in effect on January 1, 2012. On January 1, 2012, the applicable interest rate for Participant A is equivalent to a level rate of 5.5 percent. Thereafter, Participant A's hypothetical account balance for subsequent accruals is credited monthly with a pay credit equal to a specified percentage of the participant's compensation during the month. In addition, Participant A's hypothetical account balance (including both of the separate accounts) is credited monthly with interest based on the third segment rate described in section 430(h)(2)(C)(iii). (vi) Facts relating to calculation of the participant's benefit. Participant A has a severance from employment on January 1, 2015 at age 65, and elects (with spousal consent) a straight life annuity commencing January 1, 2015. On January 1, 2015, the opening hypothetical account balance, with interest credits from January 1, 2012, to January 1, 2015, has become $95,000, which, using the conversion factors under the plan on January 1, 2015, is equivalent to a straight life annuity of $1,005 per month commencing on January 1, 2015 (which is greater than the $1,000 a month payable at age 65 under the terms of the plan in effect before January 1, 2012). This benefit is in addition to the benefit determined using the hypothetical account balance for service after January 1, 2012. (vii) Conclusion. The benefit satisfies the requirements of paragraph (c)(3)(ii)(A) of this section with respect to Participant A because A's benefit is not less than the sum of (A) the greater of Participant A's benefits attributable to the opening hypothetical account balance and A's section 411(d)(6) protected benefit (as defined in § 1.411(d)-3(g)(14) ) with respect to service before the effective date of the conversion amendment, determined under the terms of the plan as in effect immediately before the effective date of the amendment, and (B) Participant A's section 411(d)(6) protected benefit with respect to service on and after the effective date of the conversion amendment, determined under the terms of the plan as in effect after the effective date of the amendment.

Example 3. (i) Facts involving a subsequent decrease in interest rates. The facts are the same as in Example 2, except that, because of a decrease in bond rates after January 1, 2012, and before January 1, 2015, the rate of interest credited in that period averages less than 5.5 percent, and, on January 1, 2015, the effective applicable interest rate under section 417(e)(3) under the plan's terms is 4.7 percent.As a result, Participant A's opening hypothetical account balance plus attributable interest credits has increased to only $87,000 on January 1, 2015, and, using the conversion factors under the plan on January 1, 2015, is equivalent to a straight life annuity commencing on January 1, 2015, of $775 per month. Under the terms of Plan E, the benefit attributable to A's opening hypothetical account balance is increased so that A's straight life annuity commencing on January 1, 2015, is $1,000 per month. This benefit is in addition to the benefit attributable to the hypothetical account balance for service after January 1, 2012. (ii) Conclusion. The benefit satisfies the requirements of paragraph (c)(3)(ii)(A) of this section with respect to Participant A because A's benefit is not less than the sum of— (A) The greater of A's benefits attributable to the opening hypothetical account balance and A's section 411(d)(6) protected benefit (as defined in § 1.411(d)-3(g)(14) ) with respect to service before the effective date of the conversion amendment, determined under the terms of the plan as in effect immediately before the effective date of the amendment; and (B) A's section 411(d)(6) protected benefit with respect to service on and after the effective date of the conversion amendment, determined under the terms of the plan as in effect after the effective date of the amendment.

Example 4. (i) Facts involving payment of a subsidized early retirement benefit. The facts are the same as in Example 2, except that under the terms of Plan E on December 31, 2011, a participant who retires before age 65 and after age 55 with 30 years of service has only a 3 percent per year actuarial reduction. Participant A has a severance from employment on January 1, 2013, when A is age 63 and has 30 years of service. On January 1, 2013, A's opening hypothetical account balance, with interest from January 1, 2012, to January 1, 2013, has become $86,000, which, using the conversion factors under the plan (as amended) on January 1, 2013, is equivalent to a straight life annuity commencing on January 1, 2013, of $850 per month.
