1.415(b)-1—Limitations for defined benefit plans.

(a) General rules— (1) Maximum limitations. Except as otherwise provided under this section, a defined benefit plan fails to satisfy the requirements of section 415(a) for a limitation year if, during the limitation year, either the annual benefit (as defined in paragraph (b)(1)(i) of this section) accrued by a participant (whether or not the benefit is vested) or the annual benefit payable to a participant at any time under the plan exceeds the lesser of—
(i) $160,000 (as adjusted pursuant to section 415(d), § 1.415(d)-1(a), and this section); or
(ii) 100 percent of the participant's average compensation for the period of the participant's high-3 years of service (as adjusted pursuant to section 415(d), § 1.415(d)-1(a), and this section).
(2) Defined benefit plan. For purposes of section 415 and regulations promulgated under section 415, a defined benefit plan is any plan, contract, or account to which section 415 applies pursuant to § 1.415(a)-1(a) or (b) (or any portion thereof) that is not a defined contribution plan within the meaning of § 1.415(c)-1(a)(2). In addition, a section 403(b) annuity contract that is not described in section 414(i) is treated as a defined benefit plan for purposes of section 415 and regulations promulgated under section 415.
(3) Plan provisions. As required in § 1.415(a)-1(d)(1), in order to satisfy the limitations on benefits under this section, the plan provisions (including the provisions of any annuity) must preclude the possibility that any annual benefit exceeding these limitations will be accrued (except as provided in paragraph (a)(7)(iii) of this section), distributed, or otherwise payable in any optional form of benefit (including the normal form of benefit) at any time (from the plan, from an annuity contract that will make distributions to the participant on behalf of the plan, or from an annuity contract that has been distributed under the plan). Thus, for example, a plan that is subject to the requirements of section 411 will fail to satisfy the limitations of this section if the plan does not contain terms that preclude the possibility that any annual benefit exceeding these limitations will be accrued or payable in any optional form of benefit (including the normal form of benefit) at any time, even though no participant has actually accrued a benefit in excess of these limitations.
(4) Adjustments to dollar limitation for commencement before age 62 or after age 65. The age-adjusted section 415(b)(1)(A) dollar limit computed pursuant to paragraph (d) or (e) of this section is used in place of the dollar limitation described in section 415(b)(1)(A) and paragraph (a)(1)(i) of this section in the case of a benefit with an annuity starting date that occurs before the participant attains age 62 or after the participant attains age 65.
(5) Average compensation for period of high-3 years of service— (i) In general. Except as otherwise provided in this paragraph (a)(5), for purposes of applying the limitation on benefits described in this section, the period of a participant's high-3 years of service is the period of 3 consecutive calendar years (taking into account the rule in paragraph (a)(5)(iii) of this section) during which the employee had the greatest aggregate compensation (as defined in § 1.415(c)-2) from the employer, and the average compensation for the period of a participant's high-3 years of service is determined by dividing the aggregate compensation for this period by 3. For purposes of this paragraph (a)(5), in determining a participant's high-3 years of service, the plan may use any 12-month period to determine a year of service instead of the calendar year, provided that it is uniformly and consistently applied in a manner that is specified under the terms of the plan. As provided under § 1.415(c)-2(f), because a plan is not permitted to base benefits on compensation in excess of the limitation under section 401(a)(17), a plan's definition of compensation for a year that is used for purposes of applying the limitations of section 415 is not permitted to reflect compensation for a year that is in excess of the limitation under section 401(a)(17) that applies to that year. See §§ 1.401(a)(17)-1(a)(3)(i) and 1.401(a)(17)-1(b)(3)(ii) for rules regarding the effective date of increases in the section 401(a)(17) compensation limitation for a plan year and for a 12-month period other than the plan year.
(ii) Short periods of service. For a participant who is employed with an employer for less than 3 consecutive years, the period of the participant's high-3 years of service is the actual number of consecutive years of service (including fractions of years, but not less than one year). In such a case, the limitation of section 415(b)(1)(B) of 100 percent of the participant's average compensation for the period of the participant's high-3 years of service is computed by dividing the participant's compensation during the participant's longest consecutive period of service by the number of years in that period (including fractions of years, but not less than one year). The rule in paragraph (a)(5)(iii) of this section is used for purposes of determining a participant's consecutive years of service.
(iii) Break in service. In the case of a participant who has had a severance from employment with an employer that maintains the plan and who is subsequently rehired by the employer, the period of the participant's high-3 years of service is calculated by excluding all years for which the participant performs no services for and receives no compensation from the employer maintaining the plan (referred to as the break period), and by treating the year of service immediately prior to and the year of service immediately after the break period as if such years of service were consecutive. See § 1.415(d)-1(a)(2)(iii) for a special rule for determining a rehired participant's section 415(b)(1)(B) compensation limit in the case of a plan that adjusts the compensation limit for limitation years after the limitation year in which the participant incurs a severance from employment.
(iv) Examples. For purposes of these examples, except as otherwise stated, the plan year and the limitation year are the calendar year, and the plan uses the calendar year for purposes of determining the period of high-3 years of service. In addition, except as otherwise stated, it is assumed that the plan's normal retirement age is 65, and all participants discussed in these examples have at least ten years of service with the employer and at least ten years of participation in the plan at issue. It is also assumed that none of the plans in the examples are governmental plans. The following examples illustrate the rules of this paragraph (a)(5):

Code of Federal Regulations

Example 1. (i) Facts. Plan A, which was established on January 1, 2008, covers Participant M, who was hired on January 1, 1990. Participant M's compensation (as defined in § 1.415(c)-2 ) from the employer maintaining the plan is $140,000 each year for 1990 through 1992, is $120,000 each year for 1993 through 2007, and is $165,000 for 2008 and 2009. Assume that for Plan A's 2008 and 2009 limitation years, the section 415(b)(1)(A) age-adjusted dollar limit for M is $185,000 and $190,000, respectively, prior to the reduction of the age-adjusted dollar limit pursuant to paragraph (g)(1) of this section (which requires a reduction in the dollar limit if a participant has less than 10 years of participation in the plan). (ii) Conclusion. As of the end of the 2008 limitation year, the period of M's high-3 consecutive years of service runs from January 1, 1990, through December 31, 1992, and M's average compensation for this period is $140,000. Thus, the limitation under section 415(b)(1)(B) for the 2008 limitation year is $140,000. As of the end of the 2009 limitation year, the period of M's high-3 consecutive years of service runs from January 1, 2007, through December 31, 2009, and M's average compensation for this period is $150,000. Thus, the limitation under section 415(b)(1)(B) for the 2009 limitation year is $150,000.

Example 2 (i) Facts. Participant N is a participant in Plan B. N's compensation for 2008, 2009, and 2010 is $300,000 for each year. N's average compensation for the period of N's high-3 years of service (determined before the application of section 401(a)(17)) is $300,000, based on N's compensation for 2008, 2009, and 2010. For all years before 2008, Participant N's compensation was less than the then-applicable section 401(a)(17) limit. On January 1, 2011, N commences receiving benefits from Plan B at the age of 75, 10 years after attaining N's normal retirement age under Plan B, when the age-adjusted section 415(b)(1)(A) dollar limit for benefits commencing at that age is $293,453. (ii) Conclusion. Pursuant to § 1.415(c)-2(f) and section 401(a)(17), Plan B is not permitted to provide for a definition of compensation that includes compensation for a year that is in excess of the limitation under section 401(a)(17) that applies to that year. Accordingly, the limitation under section 415(b)(1)(B) based on N's average compensation for the period of N's high three years of service must not reflect compensation for a year that is in excess of the limitation under section 401(a)(17) that applies to that year. Thus, if the limitation under section 401(a)(17) for years beginning in 2008, 2009, and 2010 is $230,000, $235,000, and $240,000, respectively, then the limitation under section 415(b)(1)(B) based on N's average compensation for the period of N's high three years of service is $235,000.

Code of Federal Regulations

Example 3. (i) Facts. The facts are the same as in Example 2, except that N commences receiving benefits from Plan B on January 1, 2008, at the age of 75, 10 years after attaining N's normal retirement age under Plan B. In addition, N's period of high three years of service is from January 1, 2003, through December 31, 2005, and N's average compensation for this period is $300,000. The section 401(a)(17) limits for 2003, 2004 and 2005 are $200,000, $205,000, and $210,000, respectively. As of December 31, 2007, pursuant to plan provisions adopted and in effect on January 1, 2007, N's accrued benefit under Plan B, payable in the form of a straight life annuity, actuarially adjusted to reflect commencement 10 years after normal retirement age, is $300,000. Plan B has not been amended during 2007, and that as of December 31, 2007, Plan B satisfied all of the requirements of section 415(b) with respect to N's accrued benefit, pursuant to statutory provisions, regulations, and other published guidance in effect immediately before the limitation year beginning on January 1, 2008. (ii) Conclusion. Under § 1.415(a)-1(g)(4) , Plan B is considered to satisfy the section 415(b)(1)(B) compensation limit with respect to N's benefit payable at age 75 of $300,000 (which N accrued prior to January 1, 2008), for limitation years beginning after December 31, 2007. This is because § 1.415(a)-1(g)(4) provides that plan provisions will not be treated as failing to satisfy the requirements of section 415(b)(1)(B) merely because the plan's definition of compensation that is used for purposes of applying the limitations of section 415(b)(1)(B) reflects compensation in excess of the section 401(a)(17) limitation for limitation years beginning before January 1, 2008. N, however, cannot accrue any additional benefits under Plan B for limitation years beginning after December 31, 2007, until N's section 415(b)(1)(B) compensation limit, as limited by § 1.415(c)-2(f) and section 401(a)(17), increases above $300,000.

Example 4. (i) Facts. Participant O participates in Plan C, maintained by Employer X. Plan C does not adjust a participant's section 415(b)(1)(B) compensation limit for limitation years after the limitation year in which the participant incurs a severance from employment. Prior to separating from employment with X in 2010, O's average compensation for O's period of high-3 years of service is $50,000, based on O's compensation for 2007, 2008, and 2009, which was $50,000 for each year. O's compensation for 2010 was $45,000. O's compensation is $0 for 2011. In 2012, O is rehired by X and resumes participation in Plan C. O's compensation in 2012 is $45,000, and is $70,000 in 2013. (ii) Conclusion. As of the end of the 2013 limitation year, O's average compensation for O's period of high-3 years of service is $53,333, based on O's compensation in 2010, 2012, and 2013. See paragraph (a)(5)(iii) of this section.

Code of Federal Regulations

Example 5. (i) Facts. The facts are the same as in Example 4, except that, in accordance with § 1.415(a)-1(d)(3)(v) , Plan C incorporates by reference section 415(d) adjustments to a participant's section 415(b)(1)(B) compensation limit for limitation years after the limitation year in which the participant incurs a severance from employment. Assume that the annual adjustment factor described in § 1.415(d)-1(a)(2)(ii) for 2011 through 2013 is 1.03 for each year. Thus, disregarding O's rehire by X, O's average compensation for O's period of high-3 years of service for the 2013 limitation year is equal to $54,636 ($50,000 * 1.03 * 1.03 * 1.03). (ii) Conclusion. Under § 1.415(d)-1(a)(2)(iii) , O's average compensation for O's period of high-3 years of service for the 2013 limitation year is $54,636.
(6) Exceptions from compensation limit. The limit under paragraph (a)(1)(ii) of this section (100 percent of the participant's average compensation for the participant's high-3 years of service) does not apply to—
(i) A governmental plan (as defined in section 414(d) );
(ii) A multiemployer plan (as defined in section 414(f) );
(iii) A collectively bargained plan that is described in section 415(b)(7); or
(iv) A participant in a plan maintained by an organization described in section 3121(w)(3)(A) who has never been a highly compensated employee (within the meaning of section 414(q)) of the organization.
(7) Special rules— (i) Total benefits not in excess of $10,000. See section 415(b)(4) and paragraph (f) of this section for an exception from the limits of section 415(b)(1) and paragraph (a)(1) of this section with respect to retirement benefits that do not exceed $10,000 for the limitation year.
(ii) Governmental plans electing during 1990. For a special limitation applicable to certain governmental plans electing the application of this rule during the first plan year beginning after December 31, 1989, see section 415(b)(10).
(iii) Defined benefit plans not subject to the requirements of In the case of a defined benefit plan that is not subject to the requirements of section 411, the limitations described in this paragraph (a) are not required to be applied to the annual benefit accrued by a participant before the benefit is payable. However, such a defined benefit plan is subject to the limitations described in this paragraph (a) with respect to the annual benefit payable to a participant at any time under the plan.
(iv) Application of compensation limitation exception to a church employee who becomes a highly compensated employee— (A) In general. If a participant who was described in paragraph (a)(6)(iv) of this section for a prior limitation year later becomes a highly compensated employee (within the meaning of section 414(q)) of the organization that maintains the defined benefit plan, the plan is not treated as failing to satisfy the compensation-based limitation described in paragraph (a)(1)(ii) of this section with respect to the participant if the requirements of paragraph (a)(7)(iv)(B) of this section are satisfied with respect to the participant.
(B) Limitation on accruals. The requirements of this paragraph (a)(7)(iv)(B) are satisfied with respect to a participant if no plan amendments increasing the participant's benefits are adopted during the limitation year in which the participant first becomes a highly compensated employee (within the meaning of section 414(q)) of the organization that maintains the plan, and there is no increase in the participant's accrued benefit derived from employer contributions (including increases as a result of increased compensation or service) in subsequent limitation years.
(b) Annual benefit— (1) In general— (A) Straight life annuities. For purposes of this section and § 1.415(b)-2, the term annual benefit means a benefit that is payable in the form of a straight life annuity. A straight life annuity means an annuity payable in equal installments for the life of the participant that terminates upon the participant's death. Examples of benefits that are not in the form of a straight life annuity include an annuity with a post-retirement death benefit and an annuity providing a guaranteed number of payments. If a benefit is payable in the form of a straight life annuity, no adjustment is made to the benefit to account for differences in the timing of payments during a year (for example, no adjustment is made on account of the annuity being payable in annual or monthly installments).
(B) Other benefit forms. With respect to a benefit payable in a form other than a straight life annuity, the annual benefit is determined as the straight life annuity payable on the first day of each month that is actuarially equivalent to the benefit payable in such other form, determined under the rules of paragraph (c) of this section.
(ii) Rules for determination of annual benefit. The annual benefit does not include the annual benefit attributable to either employee contributions or rollover contributions (as described in sections 401(a)(31), 402(c)(1), 403(a)(4), 403(b)(8), 408(d)(3), and 457(e)(16)), determined pursuant to the rules of paragraph (b)(2) of this section. The treatment of transferred benefits is determined under the rules of paragraph (b)(3) of this section. Paragraph (b)(4) of this section discusses the treatment of qualified governmental excess benefit arrangements.
(iii) Determination of annual benefit in the case of multiple annuity starting dates— (A) General rule. If a participant has or will have distributions commencing at more than one annuity starting date, then the limitations of section 415 must be satisfied as of each of the annuity starting dates, taking into account the benefits that have been or will be provided at all of the annuity starting dates. This will happen, for example, where benefit distributions to a participant have previously commenced under a plan that is aggregated for purposes of section 415 with a plan under which the participant receives current accruals. In determining the annual benefit for such a participant as of a particular annuity starting date, the plan must actuarially adjust the past and future distributions with respect to the benefits that commenced at the other annuity starting dates. For limitation years to which § 1.415(b)-2 applies, these adjustments must be made using the rules of § 1.415(b)-2. For purposes of this paragraph (b)(1)(iii) and § 1.415(b)-2, the determination of whether a new annuity starting date has occurred is made without regard to the rule of § 1.401(a)-2 0, Q&A-10(d) (under which the commencement of certain distributions may not give rise to a new annuity starting date).
(B) Scope of multiple annuity starting date rules. The rules provided in this paragraph (b)(1)(iii) and § 1.415(b)-2 apply for purposes of determining the annual benefit of a participant where a new distribution election is effective during the current limitation year with respect to a distribution that previously commenced. The rules of this paragraph (b)(1)(iii) and § 1.415(b)-2 also apply for determining the annual benefit of a participant for purposes of applying the limitations of section 415(b) and this section where benefit payments are increased as a result of plan terms or a plan amendment applying a cost-of-living adjustment or similar benefit increase, unless the increase is described in paragraph (b)(1)(iii)(C) of this section.
(C) Safe harbors for certain benefit increases. An increase to benefit payments as a result of plan terms or a plan amendment applying a cost-of-living adjustment or similar benefit increase is described in this paragraph (b)(1)(iii)(C) if the increase—
(1) Has previously been accounted for as part of the annual benefit under the rules of paragraph (c) of this section;
(2) Is not required to be accounted for as part of the annual benefit, pursuant to the exception for certain automatic benefit increase features under paragraph (c)(5) of this section;
(3) Is pursuant to a plan provision that automatically incorporates section 415(d) cost-of-living adjustments under § 1.415(a)-1(d)(3)(v); or
(4) Complies with one of the safe harbors described in § 1.415(d)-1(a)(5) or (6) (providing safe harbors for annual and other periodic adjustments to distributions).
(2) Determination of annual benefit attributable to employee contributions and rollover contributions— (i) In general. If employee contributions (other than contributions described in paragraph (b)(2)(ii) of this section) or rollover contributions are made to the plan, the annual benefit attributable to these contributions is determined as provided in this paragraph (b)(2).
(ii) Certain employee contributions disregarded. For purposes of this paragraph (b)(2), the following are not treated as employee contributions:
(A) Contributions that are picked up by a governmental employer as provided under section 414(h)(2).
(B) Repayment of any loan made to a participant from the plan.
(C) Repayment of a previously distributed amount as described in section 411(a)(7)(B) in accordance with section 411(a)(7)(C).
(D) Repayment of a withdrawal of employee contributions as provided under section 411(a)(3)(D).
(E) Repayments that would have been described in paragraph (b)(2)(ii)(C) or (b)(2)(ii)(D) of this section except that the plan does not restrict the timing of repayments to the maximum extent permitted by section 411(a).
(iii) Annual benefit attributable to mandatory employee contributions. In the case of mandatory employee contributions as defined in section 411(c)(2)(C) and § 1.411(c)-1(c)(4) (or contributions that would be mandatory employee contributions if section 411 applied to the plan), the annual benefit attributable to those contributions is determined by applying the factors applicable to mandatory employee contributions as described in section 411(c)(2)(B) and (C) and regulations promulgated under section 411 to those contributions to determine the amount of a straight life annuity commencing at the annuity starting date, regardless of whether the requirements of sections 411 and 417 apply to that plan. For purposes of applying such factors to a plan that is not subject to the requirements of section 411, the applicable effective date of section 411(a)(2) (which is used under § 1.411(c)-1(c)(3) to determine the beginning date from which statutorily specified interest must be credited to mandatory employee contributions) must be determined as if section 411 applied to the plan, and in determining the annual benefit that is actuarially equivalent to these accumulated contributions, the plan must determine the interest rate that would have been required under section 417(e)(3) as if section 417 applied to the plan. See § 1.415(c)-1(a)(2)(ii)(B) and (b)(3) for rules regarding treatment of mandatory employee contributions to a defined benefit plan as annual additions under a defined contribution plan.
(iv) Voluntary employee contributions. If voluntary employee contributions are made to the plan, the portion of the plan to which voluntary employee contributions are made is treated as a defined contribution plan pursuant to section 414(k) and, accordingly, is a defined contribution plan pursuant to § 1.415(c)-1(a)(2)(i). Accordingly, the portion of a plan to which voluntary employee contributions are made is not a defined benefit plan within the meaning of paragraph (a)(2) of this section and is not taken into account in determining the annual benefit under the portion of the plan that is a defined benefit plan.
(v) Annual benefit attributable to rollover contributions. The annual benefit attributable to rollover contributions from an eligible retirement plan, as defined in section 402(c)(8)(B) (for example, a contribution received pursuant to a direct rollover under section 401(a)(31)(A) ), is determined in the same manner as the annual benefit attributable to mandatory employee contributions if the plan provides for a benefit derived from the rollover contribution (other than a benefit derived from a separate account to be maintained with respect to the rollover contribution and actual earnings and losses thereon). Thus, in the case of rollover contributions from a defined contribution plan to a defined benefit plan to provide an annuity distribution, the annual benefit attributable to those rollover contributions for purposes of section 415(b) is determined by applying the rules of section 411(c) as described in paragraph (b)(2)(iii) of this section, regardless of the assumptions used to compute the annuity distribution under the plan and regardless of whether the plan is subject to the requirements of sections 411 and 417. Accordingly, in such a case, if the plan uses more favorable factors than those specified in section 411(c) to determine the amount of annuity payments arising from rollover contributions, the annual benefit under the plan would reflect the excess of those annuity payments over the amounts that would be payable using the factors specified in section 411(c). See § 1.415(c)-1(b)(3)(i) for rules excluding rollover contributions maintained in a separate account that is treated as a defined contribution plan pursuant to section 414(k) from annual additions to a defined contribution plan.
(3) Treatment of transferred benefits— (i) In general— Except as provided in paragraph (b)(3)(ii) of this section, when there has been a transfer of benefits from one defined benefit plan to another plan, to the extent the benefits transferred to the transferee plan are otherwise required to be taken into account pursuant to section 415(f) and § 1.415(f)-1 in determining whether the transferor plan satisfies the limitations of section 415(b) for a limitation year, the transferred benefits are not treated as being provided under the transferor plan. This will occur, for example, if the employer sponsoring the transferor plan and the employer sponsoring the transferee plan are in the same controlled group within the meaning of section 414(b).
(B) Treatment of transferor plan if transferred benefits are not aggregated with transferor plan. Except as provided in paragraph (b)(3)(ii) of this section, when there has been a transfer of benefits from one defined benefit plan to another plan, to the extent the benefits transferred to the transferee plan are not otherwise required to be taken into account pursuant to section 415(f) and § 1.415(f)-1 in determining whether the transferor plan satisfies the limitations of section 415(b) for a limitation year, the transferred benefits are treated by the transferor plan as if such benefits were provided under annuities purchased to provide benefits under a plan that must be aggregated with the transferor plan and that terminated immediately prior to the transfer with sufficient assets to pay all benefit liabilities under the plan, in accordance with the rules of paragraph (b)(5)(i) of this section. This will occur, for example, in the case of a transfer of benefits between defined benefit plans maintained by employers that are not required to be aggregated under sections 414(b) and (c) (as modified by section 415(h)) or sections 414(m).
(C) Treatment of transferee plan. Except as provided in paragraph (b)(3)(ii) of this section, where there has been a transfer of benefits from one defined benefit plan to another defined benefit plan, the transferee plan must take into account the transferred benefits in determining whether it satisfies the limitations of section 415(b).
(ii) Elective transfer of distributable benefit. Where, as described in § 1.411(d)-4, Q&A-3(c) (permitting certain elective transfers of distributable benefits), a distributable benefit is transferred to a defined benefit plan from either a defined contribution plan or a defined benefit plan, the amount transferred is treated as a benefit paid from the transferor plan, and the annual benefit provided by the transferee defined benefit plan does not include the annual benefit attributable to the amount transferred (determined as if the transferred amount were a rollover contribution subject to the rules of paragraph (b)(2)(v) of this section). The rule in the preceding sentence applies regardless of whether the requirements of section 411 apply to the plan and, in the case of a transfer from a defined contribution plan that is not subject to the requirements of section 411 (such as a governmental plan) to a defined benefit plan, the rule applies even if the participant's benefits are not distributable from the defined contribution plan at the time of the transfer.
(4) Treatment of qualified governmental excess benefit arrangements. Pursuant to section 415(m), in determining whether a governmental plan (as defined in section 414(d)) meets the requirements of this section, the annual benefit does not include benefits provided under a qualified governmental excess benefit arrangement, as defined in section 415(m)(3). Thus, the limitation of section 415(b) does not apply to benefits to the extent the benefits are provided under a qualified governmental excess benefit arrangement.
(5) Treatment of benefits provided under a terminated plan— (i) Terminated plan with sufficient assets. If a defined benefit plan is terminated with sufficient assets for the payment of the benefit liabilities of all plan participants and a participant in the plan has not yet commenced benefits under the plan, for purposes of satisfying section 415(b) with respect to the participant, all other defined benefit plans maintained by the employer that maintained the terminated plan are required to take into account the benefits provided pursuant to the annuities purchased to provide benefits under the terminated plan at each possible annuity starting date. In such a case, see paragraph (b)(1)(iii) of this section for rules regarding the determination of a participant's annual benefit if the participant commences receiving benefits under the terminated plan.
(ii) Terminated plan with insufficient assets. If a defined benefit plan is terminated and there are not sufficient assets for the payment of the benefit liabilities of all plan participants, for purposes of satisfying section 415(b) with respect to a participant, all other defined benefit plans maintained by the employer that maintained the terminated plan are required to take into account the benefits that are actually provided to the participant under the terminated plan. For example, in the case of a plan that is subject to Title IV of the Employee Retirement Income Security Act of 1974 (88 Stat. 829), Public Law 93-406 (ERISA), and that terminates with insufficient assets for the payment of the benefit liabilities of all plan participants, all other defined benefit plans maintained by the employer that maintained the terminating plan must take into account benefits that are paid by the Pension Benefit Guaranty Corporation. In such a case, see paragraph (b)(1)(iii) of this section for rules regarding the determination of a participant's annual benefit if the participant commences receiving benefits under the terminated plan.
(iii) Other guidance. The Commissioner may provide guidance regarding the rules applicable to terminated plans (and plans that are deemed to have been terminated pursuant to paragraph (b)(3)(i)(B) of this section) in revenue rulings, notices, and other guidance published in the Internal Revenue Bulletin. See § 601.601(d) of this chapter.
(c) Adjustment to form of benefit for forms other than a straight life annuity— (1) In general. This paragraph (c) provides rules for adjusting a form of benefit other than a straight life annuity to an actuarially equivalent straight life annuity beginning at the same time for purposes of determining the annual benefit described in paragraph (b) of this section. Paragraph (c)(2) of this section describes how to adjust a benefit paid in a form to which section 417(e)(3) does not apply. Paragraph (c)(3) of this section describes how to adjust a benefit paid in a form to which section 417(e)(3) applies. Paragraph (c)(4) of this section describes benefit forms for which no adjustment is required. Paragraph (c)(5) of this section provides an exception from the requirements of this paragraph (c) with respect to certain automatic benefit increase features. Paragraph (c)(6) of this section sets forth examples illustrating the application of this paragraph (c). The Commissioner may, in revenue rulings, notices, or other guidance published in the Internal Revenue Bulletin set forth simplified methods for adjusting a form of benefit other than a straight life annuity to an actuarially equivalent straight life annuity beginning at the same time for purposes of determining the annual benefit described in paragraph (b) of this section. See § 601.601(d)(2) of this chapter.
(2) Benefits paid in a form to which For a benefit paid in a form to which section 417(e)(3) does not apply, the actuarially equivalent straight life annuity benefit is the greater of—
(i) The annual amount of the straight life annuity (if any) payable to the participant under the plan commencing at the same annuity starting date as the form of benefit payable to the participant; or
(ii) The annual amount of the straight life annuity commencing at the same annuity starting date that has the same actuarial present value as the form of benefit payable to the participant, computed using a 5 percent interest assumption and the applicable mortality table described in § 1.417(e)-1(d)(2) for that annuity starting date.
(3) Benefits paid in a form to which (i) In general. Except as otherwise provided in this paragraph (c)(3), for a benefit paid in a form to which section 417(e)(3) applies, the actuarially equivalent straight life annuity benefit is the greatest of:
(A) The annual amount of the straight life annuity commencing at the annuity starting date that has the same actuarial present value as the particular form of benefit payable, computed using the interest rate and mortality table, or tabular factor, specified in the plan for actuarial equivalence;
(B) The annual amount of the straight life annuity commencing at the annuity starting date that has the same actuarial present value as the particular form of benefit payable, computed using a 5.5 percent interest assumption and the applicable mortality table for the distribution under § 1.417(e)-1(d)(2); or
(C) The annual amount of the straight life annuity commencing at the annuity starting date that has the same actuarial present value as the particular form of benefit payable (computed using the applicable interest rate for the distribution under § 1.417(e)-1(d)(3) and the applicable mortality table for the distribution under § 1.417(e)-1(d)(2) ), divided by 1.05.
(ii) Special rule for distributions in plan years beginning in 2004 and 2005. For a distribution to which section 417(e)(3) applies and which has an annuity starting date occurring in plan years beginning in 2004 or 2005, except as provided in section 101(d)(3) of the Pension Funding Equity Act of 2004, Public Law 108-218 (118 Stat. 596), the actuarially equivalent straight life annuity benefit is the greater of—
(A) The annual amount of the straight life annuity commencing at the annuity starting date that has the same actuarial present value as the particular form of benefit payable, computed using the interest rate and mortality table, or tabular factor, specified in the plan for actuarial equivalence; or
(B) The annual amount of the straight life annuity commencing at the annuity starting date that has the same actuarial present value as the particular form of benefit payable, computed using a 5.5 percent interest assumption and the applicable mortality table for the distribution under § 1.417(e)-1(d)(2).
(4) Certain benefit forms for which no adjustment is required— (i) In general. For purposes of the adjustments described in this paragraph (c), the following benefits are not taken into account:
(A) Survivor benefits payable to a surviving spouse under a qualified joint and survivor annuity (as defined in section 417(b)) to the extent that such benefits would not be payable if the participant's benefit were not paid in the form of a qualified joint and survivor annuity.
(B) Ancillary benefits that are not directly related to retirement benefits, such as preretirement disability benefits not in excess of the qualified disability benefit, preretirement incidental death benefits (including a qualified preretirement survivor annuity), and post-retirement medical benefits.
(ii) Rules of application— (A) Social security supplements. Although a social security supplement described in section 411(a)(9) and § 1.411(a)-7(c)(4) may be an ancillary benefit, it is included in determining the annual benefit because it is payable upon retirement and therefore is directly related to retirement income benefits.
(B) Qualified joint and survivor annuities combined with other distributions. If benefits are paid partly in the form of a qualified joint and survivor annuity (QJSA) and partly in some other form (such as a single-sum distribution), the rule of paragraph (c)(4)(i)(A) of this section (under which survivor benefits are not included in determining the annual benefit) applies to the survivor annuity payments under the portion of the benefit that is paid in the form of a QJSA.
(5) Exception for certain automatic benefit increase features— (i) General rule. Notwithstanding paragraph (b)(1)(i)(B) of this section, no adjustment is required to a benefit that is paid in a form that is not a straight life annuity to take into account the inclusion in that form of an automatic benefit increase feature, as described in paragraph (c)(5)(ii) of this section, if:
(A) The benefit is paid in a form to which section 417(e)(3) does not apply.
(B) The plan satisfies the requirements of paragraph (c)(5)(iii) of this section.
(ii) Definition of automatic benefit increase feature. An automatic benefit increase feature is included in a form of benefit if that form provides for automatic, periodic increases to the benefits paid in that form, such as a form of benefit that automatically increases the benefit paid under that form annually according to a specified percentage or objective index, or a form of benefit that automatically increases the benefit paid in that form to share favorable investment returns on plan assets.
(iii) Requirements. A plan satisfies the requirements of this paragraph (c)(5)(iii) with respect to a form of benefit that includes an automatic benefit increase feature if the form of benefit without regard to the automatic benefit increase feature satisfies the requirements of section 415(b) and this section, and the plan provides that in no event will the amount payable to the participant under the form of benefit in any limitation year be greater than the section 415(b) limit applicable at the annuity starting date (which is the lesser of the age-adjusted section 415(b)(1)(A) dollar limit described in paragraph (a)(1)(i) of this section or the section 415(b)(1)(B) compensation limit described in paragraph (a)(1)(ii) of this section), as increased in subsequent years pursuant to section 415(d) and § 1.415(d)-1. If the form of benefit without regard to the automatic benefit increase feature is not a straight life annuity, then the preceding sentence is applied by reducing the section 415(b) limit applicable at the annuity starting date to an actuarially equivalent amount (determined using the assumptions specified in paragraph (c)(2)(ii) of this section) that takes into account the death benefits under the form of benefit (other than the survivor portion of a QJSA).
(6) Examples. The following examples illustrate the provisions of this paragraph (c). For purposes of these examples, except as otherwise stated, actuarial equivalence under the plan is determined using a 5 percent interest assumption and the mortality table that applies under section 417(e)(3) as of January 1, 2003. It is assumed for purposes of these examples that the interest rate that applies under section 417(e)(3) and § 1.417(e)-1(d)(3) for relevant time periods is 5.25 percent and that the mortality table that applies under section 417(e)(3) and § 1.417(e)-1(d)(2) for relevant time periods is the mortality table that applies under section 417(e)(3) as of January 1, 2003. In addition, it is assumed that all participants discussed in these examples have at least ten years of service with the employer and at least ten years of participation in the plan at issue, all payments other than a payment of a single sum are made monthly, on the first day of each calendar month, and each plan's normal retirement age is 65. The examples are as follows:

Code of Federal Regulations

Example 1. (i) Facts. Plan A provides a single-sum distribution determined as the actuarial present value of the straight life annuity payable at the actual retirement date. Plan A provides that a participant's single sum is determined as the greater of the present value determined using the otherwise applicable actuarial assumptions of the plan and the present value determined using the applicable interest rate and the applicable mortality table for the distribution under section 417(e)(3). In accordance with § 1.417(e)-1(d)(1) , Plan A also provides that the single sum is not less than the actuarial present value of the accrued benefit payable at normal retirement age, determined using the applicable interest rate and the applicable mortality table under section 417(e)(3) and § 1.417(e)-1(d) . Participant M retires at age 65 with a benefit under the plan formula (and before the application of section 415) of $152,619 and elects to receive a distribution in the form of a single sum. Under the plan and before the application of section 415, the amount of the single sum is $1,800,002 (which is based on the 5 percent interest rate and applicable mortality table as of January 1, 2003, since that present value is greater than the present value that would have been determined using the applicable interest rate (5.25 percent) and the applicable mortality table (the January 1, 2003, table) for the distribution under section 417(e)(3)). (ii) Conclusion. For purposes of this section, the annual benefit is the greatest of the annual amount of the actuarially equivalent straight life annuity commencing at the same age (determined using the plan's actuarial factors), the annual amount of the actuarially equivalent straight life annuity commencing at the same age (determined using a 5.5 percent interest assumption and the applicable mortality table for the distribution under § 1.417(e)-1(d)(2) ), and the annual amount of the actuarially equivalent straight life annuity commencing at the same age (determined using the applicable interest rate and applicable mortality table for the distribution under §§ 1.417(e)-1(d)(2) and (d)(3) ) divided by 1.05. Based on the factors used in the plan to determine the actuarially equivalent lump sum (in this case, an interest rate of 5 percent and the applicable mortality table as of January 1, 2003), $1,800,002 payable as a single sum is actuarially equivalent to an immediate straight life annuity at age 65 of $152,619. A single sum payment of $1,800,002 is actuarially e
