Paragraph 1.  The authority citation for part 1 is amended by adding
                           an entry to read, in part, as follows:
                        
                        Authority:  26 U.S.C. 7805 * * *
                        §1.411(d)-3 also issued under 26 U.S.C. 411(d)(6) and section 645(b)
                           of the Economic Growth and Tax Relief Reconciliation Act of 2001, Public Law
                           107-16 (115 Stat. 38).* * *
                        
                        Par. 2.  Section 1.411(d)-3 is revised to read as follows:
                        
                           
                              
                                 
                                    §1.411(d)-3  Section 411(d)(6) protected benefits.
                                  
                               
                              
                            
                           (a) Protection of accrued benefits—(1) General
                                    rule.  Under section 411(d)(6)(A), a plan is not a qualified plan
                              (and a trust forming a part of such plan is not a qualified trust) if a plan
                              amendment decreases the accrued benefit of any plan participant, except as
                              provided in section 412(c)(8), section 4281 of the Employee Retirement Income
                              Security Act of 1974 as amended (ERISA), or other applicable law (e.g.,
                              section 1541(a)(2) of the Taxpayer Relief Act of 1997, Public Law 105-34 (111
                              Stat. 788, 1085)).  For purposes of this section, a plan amendment includes
                              any changes to the terms of a plan, including changes resulting from a merger,
                              consolidation, or transfer (as defined in section 414(l)) or a plan termination.
                               The protection of section 411(d)(6) applies to a participant’s entire
                              accrued benefit under the plan as of the applicable amendment date, without
                              regard to whether the entire accrued benefit was accrued before a participant’s
                              severance from employment or whether any portion was the result of an increase
                              in the accrued benefit of the participant pursuant to a plan amendment adopted
                              after the participant’s severance from employment.
                           
                           (2) Plan provisions taken into account—(i) Direct
                                    or indirect reduction in accrued benefit.  For purposes of determining
                              whether a participant’s accrued benefit is decreased, all of the amendments
                              to the provisions of a plan affecting, directly or indirectly, the computation
                              of accrued benefits are taken into account.  Plan provisions indirectly affecting
                              the computation of accrued benefits include, for example, provisions relating
                              to years of service and compensation.
                           
                           (ii) Amendments effective with the same applicable amendment
                                    date.  In determining whether a reduction in a participant’s
                              accrued benefit has occurred, all plan amendments with the same applicable
                              amendment date are treated as one amendment.  Thus, if two amendments have
                              the same applicable amendment date and one amendment, standing alone, increases
                              participants’ accrued benefits and the other amendment, standing alone,
                              decreases participants’ accrued benefits, the amendments are treated
                              as one amendment and will only violate section 411(d)(6) if, for any participant,
                              the net effect is to decrease participants’ accrued benefit as of that
                              applicable amendment date.
                           
                           (iii) Multiple amendments—(A) General
                                    rule.  A plan amendment violates the requirements of section 411(d)(6)
                              if it is one of a series of plan amendments that, when taken together, have
                              the effect of reducing or eliminating a section 411(d)(6) protected benefit
                              in a manner that would be prohibited by section 411(d)(6) if accomplished
                              through a single amendment.
                           
                           (B) Determination of the time period for combining plan amendments.
                               For purposes of applying the rule in paragraph (a)(2)(iii)(A) of this section,
                              generally only plan amendments adopted within a 3-year period are taken into
                              account.
                           
                           (3) Application of section 411(a) nonforfeitability provisions
                                    with respect to section 411(d)(6) protected benefits.  [Reserved].
                           
                           (4) Examples.  The following examples illustrate
                              the application of this paragraph (a):
                           
                           Example 1.  (i) Facts.  Plan
                              A provides an annual benefit of 2% of career average pay times years of service
                              commencing at normal retirement age (age 65).  Plan A is amended on November
                              1, 2006, effective as of January 1, 2007, to provide for an annual benefit
                              of 1.3% of final pay times years of service, with final pay computed as the
                              average of a participant’s highest 3 consecutive years of compensation.
                               As of January 1, 2007, Participant M has 16 years of service, M’s career
                              average pay is $37,500, and the average of M’s highest 3 consecutive
                              years of compensation is $67,308.  Thus, Participant M’s accrued benefit
                              as of the applicable amendment date is increased from $12,000 per year at
                              normal retirement age (2% times $37,500 times 16 years of service) to $14,000
                              per year at normal retirement age (1.3% times $67,308 times 16 years of service).
                               As of January 1, 2007, Participant N has 6 years of service, N’s career
                              average pay is $50,000, and the average of N’s highest 3 consecutive
                              years of compensation is $51,282.  Participant N’s accrued benefit as
                              of the applicable amendment date is decreased from $6,000 per year at normal
                              retirement age (2% times $50,000 times 6 years of service) to $4,000 per year
                              at normal retirement age (1.3% times $51,282 times 6 years of service).
                           
                           (ii)  Conclusion.  While the plan amendment increases
                              the accrued benefit of Participant M, the plan amendment fails to satisfy
                              the requirements of section 411(d)(6)(A) because the amendment decreases the
                              accrued benefit of Participant N below the level of the accrued benefit of
                              Participant N immediately before the applicable amendment date.
                           
                           Example 2.  (i) Facts.  The
                              facts are the same as Example 1, except that Plan A includes
                              a provision under which Participant N’s accrued benefit cannot be less
                              than what it was immediately before the applicable amendment date (so that
                              Participant N’s accrued benefit could not be less than $6,000 per year
                              at normal retirement age).
                           
                           (ii) Conclusion.  The amendment does not violate
                              the requirements of section 411(d)(6)(A) with respect to Participant M (whose
                              accrued benefit has been increased) or with respect to Participant N (although
                              Participant N would not accrue any benefits until the point in time at which
                              the new formula amount would exceed the amount payable under the minimum provision,
                              approximately 3 years after the amendment becomes effective).
                           
                           (b) Protection of section 411(d)(6)(B) protected benefits—(1) General
                                    rule—(i) Prohibition against plan amendments eliminating
                                    or reducing section 411(d)(6)(B) protected benefits.  Except as
                              provided in this section, a plan is treated as decreasing an accrued benefit
                              if it is amended to eliminate or reduce a section 411(d)(6)(B) protected benefit
                              as defined in paragraph (g)(15) of this section.  This paragraph (b)(1) applies
                              to participants who satisfy (either before or after the plan amendment) the
                              preamendment conditions for a section 411(d)(6)(B) protected benefit.
                           
                           (ii) Contingent benefits.  The rules of paragraph
                              (b)(1)(i) of this section apply to participants who satisfy (either before
                              or after the plan amendment) the preamendment conditions for the section 411(d)(6)(B)
                              protected benefit even if the condition on which the eligibility for the section
                              411(d)(6)(B) protected benefit depends is an unpredictable contingent event
                              (e.g., a plant shutdown).
                           
                           (iii) Application of general rules in paragraph (a) of this
                                    section to section 411(d)(6)(B) protected benefits.  For purposes
                              of determining whether a participant’s section 411(d)(6)(B) protected
                              benefit is eliminated or reduced, the rules of paragraph (a) of this section
                              apply to section 411(d)(6)(B) protected benefits in the same manner as they
                              apply to accrued benefits described in section 411(d)(6)(A).  As an example
                              of the application of paragraph (a)(2)(ii) of this section to section 411(d)(6)(B)
                              protected benefits, if there are two amendments with the same applicable amendment
                              date and one amendment increases accrued benefits and the other amendment
                              decreases the early retirement factors that are used to determine the early
                              retirement annuity, the amendments are treated as one amendment and only violate
                              section 411(d)(6) if, after the two amendments, the net dollar amount of any
                              early retirement annuity with respect to the accrued benefit of any participant
                              as of the applicable amendment date is lower than it would have been without
                              the two amendments.  As an example of the application of paragraph (a)(2)(iii)
                              of this section to section 411(d)(6)(B) protected benefits, a series of amendments
                              made within a 3-year period that, when taken together, have the effect of
                              reducing or eliminating early retirement benefits or retirement-type subsidies
                              in a manner that adversely affects the rights of any participant in a more
                              than de minimis manner violates section 411(d)(6)(B)
                              even if each amendment would be permissible pursuant to paragraphs (c), (d),
                              or (f) of this section.
                           
                           (2) Permissible elimination of section 411(d)(6)(B) protected
                                    benefits—(i) In general.  A plan is
                              permitted to be amended to eliminate a section 411(d)(6)(B) protected benefit
                              if the elimination is in accordance with this section or §1.411(d)-4.
                           
                           (ii) Increases in payment amounts do not eliminate an optional
                                    form of benefit.  An amendment is not treated as eliminating an
                              optional form of benefit or eliminating or reducing an early retirement benefit
                              or retirement-type subsidy under the plan, if, effective after the plan amendment,
                              there is another optional form of benefit available to the participant under
                              the plan that is of inherently equal or greater value (within the meaning
                              of §1.401(a)(4)-4(d)(4)(i)(A)).  Thus, for example, a change in the method
                              of calculating a joint and survivor annuity from using a 90% adjustment factor
                              on account of the survivorship payment at particular ages for a participant
                              and a spouse to using a 91% adjustment factor at the same ages is not treated
                              as an elimination of an optional form of benefit.  Similarly, a plan that
                              offers a subsidized qualified joint and survivor annuity option for married
                              participants under which the amount payable during the participant’s
                              lifetime is not less than the amount payable under the plan’s straight
                              life annuity is permitted to be amended to eliminate the straight life annuity
                              option for married participants.
                           
                           (3) Permissible elimination of benefits that are not section
                                    411(d)(6) protected benefits—(i) In general.
                               Section 411(d)(6) does not provide protection for benefits that are ancillary
                              benefits, other rights and features, or any other benefits that are not described
                              in section 411(d)(6).  See §1.411(d)-4, Q&A-1(d).  However, a plan
                              may not be amended to recharacterize a retirement-type benefit as an ancillary
                              benefit.  Thus, for example, a plan amendment to recharacterize any portion
                              of an early retirement subsidy as a social security supplement that is an
                              ancillary benefit violates section 411(d)(6).
                           
                           (ii) No protection for future benefit accruals.
                               Section 411(d)(6) only protects benefits that accrue before the applicable
                              amendment date.  Thus, a plan is permitted to be amended to eliminate or reduce
                              an early retirement benefit, a retirement-type subsidy, or an optional form
                              of benefit with respect to benefits that accrue after the applicable amendment
                              date without violating section 411(d)(6).  However, section 4980F(e) of the
                              Internal Revenue Code and section 204(h) of ERISA require notice of an amendment
                              to an applicable pension plan that either provides for a significant reduction
                              in the rate of future benefit accrual or that eliminates or significantly
                              reduces an early retirement benefit or a retirement-type subsidy.  See §54.4980F-1
                              of this chapter generally, and see §54.4980F-1, Q&A-7(b) and Q&A-8(c)
                              of this chapter, with respect to the circumstances under which such notice
                              is required for a reduction in an early retirement benefit or retirement-type
                              subsidy.
                           
                           (4) Examples.  The following examples illustrate
                              the application of this paragraph (b):
                           
                           Example 1.  (i) Facts involving amendments
                                    to an early retirement subsidy.  Plan A provides an annual benefit
                              of 2% of career average pay times years of service commencing at normal retirement
                              age (age 65).  Plan A is amended on November 1, 2006, effective as of January
                              1, 2007, to provide for an annual benefit of 1.3% of final pay times years
                              of service, with final pay computed as the average of a participant’s
                              highest 3 consecutive years of compensation.  Participant M is age 50, M has
                              16 years of service, M’s career average pay is $37,500, and the average
                              of M’s highest 3 consecutive years of compensation is $67,308.  Thus,
                              M’s accrued benefit as of the effective date of the amendment is increased
                              from $12,000 per year at normal retirement age (2% times $37,500 times 16
                              years of service) to $14,000 per year at normal retirement age (1.3% times
                              $67,308 times 16 years of service).  (These facts are similar to the facts
                              in Example 1 in paragraph (a)(4) of this section.)  Before
                              the amendment, Plan A permitted a former employee to commence distribution
                              of benefits as early as age 55 and, for a participant with at least 15 years
                              of service, actuarially reduced the amount payable in the form of a straight
                              life annuity commencing before normal retirement age by 3% per year from age
                              60 to age 65 and by 7% per year from age 55 through age 59.  Thus, before
                              the amendment, the amount of M’s early retirement benefit that would
                              be payable for commencement at age 55 was $6,000 per year ($12,000 per year
                              minus 3% for 5 years and minus 7% for 5 more years).  The amendment also alters
                              the actuarial reduction factor so that, for a participant with at least 15
                              years of service, the amount payable in a straight life annuity commencing
                              before normal retirement age is reduced by 6% per year.  As a result, the
                              amount of M’s early retirement benefit at age 55 becomes $5,600 per
                              year after the amendment ($14,000 minus 6% for 10 years).
                           
                           (ii)  Conclusion.  The straight life annuity payable
                              under Plan A at age 55 is an optional form of benefit that includes an early
                              retirement subsidy.  The plan amendment fails to satisfy the requirements
                              of section 411(d)(6)(B) because the amendment decreases the optional form
                              of benefit payable to Participant M below the level that Participant M was
                              entitled to receive immediately before the effective date of the amendment.
                               If instead Plan A had included a provision under which M’s straight
                              life annuity payable at any age could not be less than what it was immediately
                              before the amendment (so that M’s straight life annuity payable at age
                              55 could not be less than $6,000 per year), then the amendment would not fail
                              to satisfy the requirements of section 411(d)(6)(B) with respect to M’s
                              straight life annuity payable at age 55 (although the straight life annuity
                              payable to M at age 55 would not increase until the point in time at which
                              the new formula amount with the new actuarial reduction factors exceeds the
                              amount payable under the minimum provision, approximately 14 months after
                              the amendment becomes effective).
                           
                           Example 2.  (i) Facts involving plant
                                    shutdown benefits.  Plan B permits participants who have a severance
                              from employment before normal retirement age (age 65) to commence distributions
                              at any time after age 55 with the amount payable to be actuarially reduced
                              using reasonable actuarial assumptions regarding interest and mortality specified
                              in the plan, but provides that the annual reduction for any participant who
                              has at least 20 years of service and who has a severance from employment after
                              age 55 is only 3% per year (which is a smaller reduction than would apply
                              under reasonable actuarial reductions).  Plan B also provides two plant shutdown
                              benefits to participants who have a severance of employment as a result of
                              a plant shutdown.  First, the favorable 3% per year actuarial reduction applies
                              for commencement of benefits after age 55 and before age 65 for any participant
                              who has at least 10 years of service and who has a severance from employment
                              as a result of a plant shutdown.  Second, all participants who have at least
                              20 years of service and who have a severance from employment after age 55
                              (and before normal retirement age at age 65) as a result of a plant shutdown
                              will receive supplemental payments.  Under the supplemental payments, an additional
                              amount equal to the participant’s estimated old-age insurance benefit
                              under the Social Security Act is payable until age 65.  The supplemental payments
                              are not a QSUPP, as defined in §1.401(a)(4)-12, because the plan’s
                              terms do not state that the supplement is treated as an early retirement benefit
                              that is protected under section 411(d)(6).
                           
                           (ii) Conclusion with respect to plant shutdown benefits.
                               The benefits payable with the 3% annual reduction are retirement-type benefits.
                               The excess of the actuarial present value of the early retirement benefit
                              using the 3% annual reduction over the actuarial present value of the normal
                              retirement benefit is a retirement-type subsidy and the right to receive payments
                              of the benefit at age 55 is an early retirement benefit.  These conclusions
                              apply not only with respect to the rights that apply to participants who have
                              at least 20 years of service, but also to participants with at least 10 years
                              of service who have a severance from employment as a result of a plant shutdown.
                               Thus, the right to receive benefits based on a 3% annual reduction for participants
                              with at least 10 years of service at the time of a plant shutdown is an early
                              retirement benefit that provides a retirement-type subsidy and is a section
                              411(d)(6)(B) protected benefit (even though no plant shutdown has occurred).
                               Therefore, a plan amendment cannot eliminate this benefit with respect to
                              benefits accrued before the applicable amendment date, even before the occurrence
                              of the plant shutdown.  Because the plan provides that the supplemental payments
                              cannot exceed the OASDI benefit under the Social Security Act, the supplemental
                              payments constitute a social security supplement (but not a QSUPP as defined
                              in §1.401(a)(4)-12), which is an ancillary benefit that is not a section
                              411(d)(6)(B) protected benefit and accordingly is not taken into account in
                              determining whether a prohibited reduction has occurred.
                           
                           (c) Permissible elimination of optional forms of benefit that
                                    are redundant—(1) General rule.  Except
                              as otherwise provided in paragraph (c)(5) of this section, a plan is permitted
                              to be amended to eliminate an optional form of benefit for a participant with
                              respect to benefits accrued before the applicable amendment date if—
                           
                           (i) The optional form of benefit is redundant with respect to a retained
                              optional form of benefit, within the meaning of paragraph (c)(2) of this section;
                           
                           (ii) The plan amendment is not applicable with respect to an optional
                              form of benefit with an annuity commencement date that is earlier than the
                              number of days in the maximum QJSA explanation period (as defined in paragraph
                              (g)(9) of this section) after the date the amendment is adopted; and
                           
                           (iii) The requirements of paragraph (e) of this section are satisfied
                              in any case in which either:
                           
                           (A) The retained optional form of benefit for the participant does not
                              commence on the same annuity commencement date as the optional form of benefit
                              that is being eliminated, or
                           
                           (B) As of the date the amendment is adopted, the actuarial present value
                              of the retained optional form of benefit for the participant is less than
                              the actuarial present value of the optional form of benefit that is being
                              eliminated.
                           
                           (2) Similar types of optional forms of benefit are redundant—(i) General
                                    rule.  An optional form of benefit is redundant with respect to
                              a retained optional form of benefit if, after the amendment becomes applicable—
                           
                           (A) There is a retained optional form of benefit available to the participant
                              that is in the same family of optional forms of benefit, within the meaning
                              of paragraphs (c)(3) and (4) of this section, as the optional form of benefit
                              being eliminated; and
                           
                           (B) The participant’s rights with respect to the retained optional
                              form of benefit are not subject to materially greater restrictions (such as
                              conditions relating to eligibility, restrictions on a participant’s
                              ability to designate the person who is entitled to benefits following the
                              participant’s death, or restrictions on a participant’s right
                              to receive an in-kind distribution) than applied to the optional form of benefit
                              being eliminated.
                           
                           (ii) Special rule for core options.  An optional
                              form of benefit that is a core option as defined in paragraph (g)(5) of this
                              section may not be eliminated as a redundant benefit under the rules of this
                              paragraph (c) unless the retained optional form of benefit and the eliminated
                              core option are identical except for differences described in paragraph (c)(3)(ii)
                              of this section.  Thus, for example, a particular 10-year term certain and
                              life annuity may not be eliminated by plan amendment unless the retained optional
                              form of benefit is another 10-year term certain and life annuity.
                           
                           (3)  Family of optional forms of benefit—(i) In
                                    general.  Paragraph (c)(4) of this section describes certain families
                              of optional forms of benefits.  Not every optional form of benefit that is
                              offered under a plan necessarily fits within a family of optional forms of
                              benefit as described in paragraph (c)(4) of this section.  Each optional form
                              of benefit that is not included in any particular family of optional forms
                              of benefit listed in paragraph (c)(4) of this section is in a separate family
                              of optional forms of benefit with other optional forms of benefit that would
                              be identical to that optional form of benefit but for differences that are
                              disregarded under paragraph (c)(3)(ii) of this section.
                           
                           (ii) Certain differences among optional forms of benefit—(A) Differences
                                    in actuarial factors and annuity starting dates.  The determination
                              of whether two optional forms of benefit are within a family of optional forms
                              of benefit is made without regard to actuarial factors or annuity starting
                              dates.  Thus, any optional forms of benefit that are part of the same generalized
                              optional form (within the meaning of paragraph (g)(8) of this section) are
                              in the same family of optional forms of benefit.  For example, if a plan has
                              a single-sum distribution option for some participants that is calculated
                              using a 5% interest rate and a specific mortality table (but no less than
                              the minimum present value as determined under section 417(e)) and another
                              single-sum distribution option for other participants that is calculated using
                              the applicable interest rate as defined in section 417(e)(3)(A)(ii)(II) and
                              the applicable mortality table as defined in section 417(e)(3)(A)(ii)(I),
                              both single-sum distribution options are part of the same generalized optional
                              form and thus in the same family of optional forms of benefit under the rules
                              of paragraph (c)(3)(i) of this section.  However, differences in actuarial
                              factors and annuity starting dates are taken into account for purposes of
                              the requirements in paragraph (e)(3) of this section.
                           
                           (B) Differences in pop-up provisions and cash refund features
                                    for joint and contingent options.  The determination of whether
                              two optional forms of benefit are within a family of optional forms of benefit
                              relating to joint and contingent families (as described in paragraph (c)(4)(i)
                              and (ii) of this section) is made without regard to the following features—
                           
                           (1) Pop-up provisions (under which payments increase
                              upon the death of the beneficiary or another event that causes the beneficiary
                              not to be entitled to a survivor annuity);
                           
                           (2) Cash refund features (under which payment is
                              provided upon the death of the last annuitant in an amount that is not greater
                              than the excess of the present value of the annuity at the annuity starting
                              date over the total of payments before the death of the last annuitant); or
                           
                           (3) Term-certain provisions for optional forms
                              of benefit within a joint and contingent family.
                           
                           (C) Differences in social security leveling features, refund
                                    of employee contributions features, and retroactive annuity starting date
                                    features.  The determination of whether two optional forms of benefit
                              are within a family of optional forms of benefit is made without regard to
                              social security leveling features, refund of employee contributions features,
                              or retroactive annuity starting date features.  But see paragraph (c)(5) of
                              this section for special rules relating to social security leveling, refund
                              of employee contributions, and retroactive annuity starting date features
                              in optional forms of benefit.
                           
                           (4) List of families.  The following are families
                              of optional forms of benefit for purposes of this paragraph (c):
                           
                           (i) Joint and contingent options with continuation percentages
                                    of 50% to 100%.  An optional form of benefit is within the 50%
                              or more joint and contingent family if it provides a life annuity to the participant
                              and a survivor annuity to an individual that is at least 50% and no more than
                              100% of the annuity payable during the joint lives of the participant and
                              the participant’s survivor.
                           
                           (ii) Joint and contingent options with continuation percentages
                                    less than 50%.  An optional form of benefit is within the less
                              than 50% joint and contingent family if it provides a life annuity to the
                              participant and a survivor annuity to an individual that is less than 50%
                              of the annuity payable during the joint lives of the participant and the participant’s
                              survivor.
                           
                           (iii) Term certain and life annuity options with a term of
                                    10 years or less.  An optional form of benefit is within the 10
                              years or less term certain and life family if it is a life annuity with a
                              guarantee that payments will continue to the participant’s beneficiary
                              for the remainder of a fixed period that is 10 years or less if the participant
                              dies before the end of the fixed period.
                           
                           (iv) Term certain and life annuity options with a term longer
                                    than 10 years.  An optional form of benefit is within the longer
                              than 10 years term certain and life family if it is a life annuity with a
                              guarantee that payments will continue to the participant’s beneficiary
                              for the remainder of a fixed period that is in excess of 10 years if the participant
                              dies before the end of the fixed period.
                           
                           (v) Level installment payment options over a period of 10
                                    years or less.  An optional form of benefit is within the 10 years
                              or less installment family if it provides for substantially level payments
                              to the participant for a fixed period of at least two years and not in excess
                              of 10 years with a guarantee that payments will continue to the participant’s
                              beneficiary for the remainder of the fixed period if the participant dies
                              before the end of the fixed period.
                           
                           (vi) Level installment payment options over a period of more
                                    than 10 years.  An optional form of benefit is within the more
                              than 10 years installment family if it provides for substantially level payments
                              to the participant for a fixed period that is in excess of 10 years with a
                              guarantee that payments will continue to the participant’s beneficiary
                              for the remainder of the fixed period if the participant dies before the end
                              of the fixed period.
                           
                           (5) Special rules for certain features included in optional
                                    forms of benefit.  For purposes of applying this paragraph (c),
                              to the extent an optional form of benefit that is being eliminated includes
                              either a social security leveling feature or a refund of employee contributions
                              feature, the retained optional form of benefit must also include that feature,
                              and, to the extent that the optional form of benefit that is being eliminated
                              does not include a social security leveling feature or a refund of employee
                              contributions feature, the retained optional form of benefit must not include
                              that feature.  For purposes of applying this paragraph (c), to the extent
                              an optional form of benefit that is being eliminated does not include a retroactive
                              annuity starting date feature, the retained optional form of benefit must
                              not include the feature.
                           
                           (d) Permissible elimination of noncore optional forms of benefit
                                    where core options are offered—(1) General rule.
                               Except as otherwise provided in paragraph (d)(2) of this section, a plan
                              is permitted to be amended to eliminate an optional form of benefit for a
                              participant with respect to benefits accrued before the applicable amendment
                              date if—
                           
                           (i) After the amendment becomes applicable, each of the core options
                              described in paragraph (g)(5) of this section is available to the participant
                              with respect to benefits accrued before and after the amendment;
                           
                           (ii) The plan amendment is not applicable with respect to an optional
                              form of benefit with an annuity commencement date that is earlier than 4 years
                              after the date the amendment is adopted; and
                           
                           (iii) The requirements of paragraph (e) of this section are satisfied
                              in any case in which either:
                           
                           (A) One or more of the core options are not available commencing on
                              the same annuity commencement date as the optional form of benefit that is
                              being eliminated, or
                           
                           (B) As of the date the amendment is adopted, the actuarial present value
                              of the benefit payable under any core option with the same annuity commencement
                              date is less than the actuarial present value of benefits payable under the
                              optional form of benefit that is being eliminated.
                           
                           (2) Special rules—(i) Treatment
                                    of certain features included in optional forms of benefit.  For
                              purposes of applying this paragraph (d), to the extent an optional form of
                              benefit that is being eliminated includes either a social security leveling
                              feature or a refund of employee contributions feature, at least one of the
                              core options must also be available with that feature, and, to the extent
                              that the optional form of benefit that is being eliminated does not include
                              a social security leveling feature or a refund of employee contributions feature,
                              each of the core options must be available without that feature.  For purposes
                              of applying this paragraph (d), to the extent an optional form of benefit
                              that is being eliminated does not include a retroactive annuity starting date
                              feature, each of the core options must be available without that feature.
                           
                           (ii) Eliminating the most valuable option for a participant
                                    with a short life expectancy.  For purposes of applying this paragraph
                              (d), if the most valuable option for a participant with a short life expectancy
                              (as defined in paragraph (g)(5)(iii) of this section) is eliminated, then,
                              after the plan amendment, an optional form of benefit that is identical, except
                              for differences described in paragraph (c)(3)(ii) of this section, must be
                              available to the participant.  However, such a plan amendment cannot eliminate
                              a refund of employee contributions feature from the most valuable option for
                              a participant with a short life expectancy.
                           
                           (iii) Single-sum distributions.  A plan amendment
                              is not treated as satisfying this paragraph (d) if it eliminates an optional
                              form of benefit that includes a single-sum distribution that applies with
                              respect to at least 25% of the participant’s accrued benefit as of the
                              date the optional form of benefit is eliminated.  But see §1.411(d)-4,
                              Q&A-2(b)(2)(v), relating to involuntary single-sum distributions for benefits
                              with a present value not in excess of the maximum dollar amount in section
                              411(a)(11).
                           
                           (iv) Application of multiple amendment rule to core option
                                    rule.  Notwithstanding paragraph (a)(2)(iii)(B) of this section,
                              if a plan is amended to eliminate an optional form of benefit using the core
                              options rule in this paragraph (d), then the employer must wait 3 years after
                              the first annuity commencement date for which the optional form of benefit
                              is no longer available before making any changes to the core options offered
                              under the plan (other than a change that is not treated as an elimination
                              under paragraph (b)(2)(ii) of this section).  Thus, for example, if a plan
                              amendment eliminates an optional form of benefit for a participant using the
                              core options rule under this paragraph (d), with an adoption date of January
                              1, 2006 and an effective date of January 1, 2010, the plan would not be permitted
                              to be amended to make changes to the core options offered under the plan (and
                              the core options would continue to apply with respect to the participant’s
                              accrued benefit) until January 1, 2013.
                           
                           (v) Special rule for joint and contingent annuity core option.
                               If a plan offers joint and contingent annuities under which a participant
                              is entitled to a life annuity with a survivor annuity for the individual designated
                              by the participant (including a non-spousal contingent annuitant) with continuation
                              percentage options of both 50% and 100% (after adjustments permitted under
                              paragraph (g)(5)(ii) of this section to comply with applicable law), the plan
                              is permitted to treat both of these options as core options for purposes of
                              this paragraph (d), in lieu of a 75% joint and contingent annuity.  Thus,
                              such a plan is permitted to use the rules of this paragraph (d) if the plan
                              satisfies all of the requirements of this paragraph (d) (taking into account
                              the modification rule in paragraph (g)(5)(ii) of this section) other than
                              the requirement of offering a 75% joint and contingent annuity as described
                              in paragraph (g)(5)(i)(B) of this section.
                           
                           (e) Permissible plan amendments under paragraphs (c) and (d)
                                    eliminating or reducing section 411(d)(6)(B) protected benefits that are burdensome
                                    and of de minimis value—(1) In general.
                               A plan amendment that, pursuant to paragraph (c)(1)(iii) or (d)(1)(iii) of
                              this section, is required to satisfy this paragraph (e) satisfies this paragraph
                              (e) if—
                           
                           (i) The amendment eliminates section 411(d)(6)(B) protected benefits
                              that create significant burdens or complexities for the plan and its participants
                              as described in paragraph (e)(2) of this section; and
                           
                           (ii) The amendment does not adversely affect the rights of any participant
                              in a more than de minimis manner as described in paragraph
                              (e)(3) of this section.
                           
                           (2) Plan amendments eliminating section 411(d)(6)(B) protected
                                    benefits that create significant burdens and complexities—(i) Facts
                                    and circumstances analysis—(A)  In general.
                               The determination of whether a plan amendment eliminates section 411(d)(6)(B)
                              protected benefits that create significant burdens or complexities for the
                              plan and its participants is based on facts and circumstances.
                           
                           (B)  Early retirement benefits.  In the case of
                              an amendment that eliminates an early retirement benefit, relevant factors
                              include whether the annuity starting dates under the plan considered in the
                              aggregate are burdensome or complex (e.g., the number
                              of categories of early retirement benefits, whether the terms and conditions
                              applicable to the plan’s early retirement benefits are difficult to
                              summarize in a manner that is concise and readily understandable to the average
                              plan participant, and whether those different early retirement benefits were
                              added to the plan as a result of a plan merger, transfer, or consolidation),
                              and whether the effect of the plan amendment is to reduce the number of categories
                              of early retirement benefits.
                           
                           (C)  Retirement-type subsidies and actuarial factors.
                               In the case of a plan amendment eliminating a retirement-type subsidy or
                              changing the actuarial factors used to determine optional forms of benefit,
                              relevant factors include whether the actuarial factors used for determining
                              optional forms of benefit available under the plan considered in the aggregate
                              are burdensome or complex (e.g., the number of different
                              retirement-type subsidies and other actuarial factors available under the
                              plan, whether the terms and conditions applicable to the plan’s retirement-type
                              subsidies are difficult to summarize in a manner that is concise and readily
                              understandable to the average plan participant, whether the plan is eliminating
                              one or more generalized optional forms, whether the plan is replacing a complex
                              optional form of benefit that contains a retirement-type subsidy with a simpler
                              form, and whether the different retirement-type subsidies and other actuarial
                              factors were added to the plan as a result of a plan merger, transfer, or
                              consolidation), and whether the effect of the plan amendment is to reduce
                              the number of categories of retirement-type subsidies or other actuarial factors.
                           
                           (D)  Example.  The following example illustrates
                              the application of this paragraph (e)(2)(i):
                           
                           Example.  (i)  Facts.  Plan
                              A is a defined benefit plan under which employees may select a distribution
                              in the form of a straight life annuity, a straight life annuity with cost-of-living
                              increases, a 50% qualified joint and survivor annuity with a pop-up provision,
                              or a 10-year term certain and life annuity.  On January 15, 2007, Plan A is
                              amended, effective June 1, 2007, to eliminate the 50% qualified joint and
                              survivor annuity with a pop-up provision as described in paragraph (c)(3)(ii)(B)(1)
                              of this section and replace it with a 50% qualified joint and survivor annuity
                              without the pop-up provision (and using the same actuarial factor).
                           
                           (ii)  Conclusion.  Plan A satisfies the requirements
                              of paragraph (e)(2)(i)(B) of this section because, based on the relevant facts
                              and circumstances (e.g., the amendment replaces a complex
                              optional form of benefit with a simpler form), the amendment eliminates section
                              411(d)(6)(B) protected benefits that create significant burdens and complexities.
                               Accordingly, the plan amendment is permitted to eliminate the pop-up provision,
                              provided that the plan amendment satisfies all the other applicable requirements
                              in paragraph (c) or (d) of this section.  For example, the plan amendment
                              must not eliminate the most valuable option for a participant with a short
                              life expectancy (as defined in paragraph (g)(5)(iii) of this section) and
                              the plan amendment must not adversely affect the rights of any participant
                              in a more than de minimis manner, taking into account
                              the actuarial factors for the joint and survivor annuity with the pop-up provision
                              and the joint and survivor annuity without the pop-up provision, as described
                              in paragraph (e)(3) of this section.
                           
                           (ii) Presumptions for certain amendments—(A) Presumption
                                    for amendments eliminating certain annuity starting dates.  If
                              the annuity starting dates under the plan considered in the aggregate are
                              burdensome or complex, then elimination of any one of the annuity starting
                              dates is presumed to eliminate section 411(d)(6)(B) protected benefits that
                              create significant burdens or complexities for the plan and its participants.
                               However, if the effect of a plan amendment with respect to a set of optional
                              forms of benefit is merely to substitute one set of annuity starting dates
                              for another set of annuity starting dates, without any reduction in the number
                              of different annuity starting dates, then the plan amendment does not satisfy
                              the requirements of this paragraph (e)(2).
                           
                           (B)  Presumption for amendments changing certain actuarial
                                    factors.  If the actuarial factors used for determining benefit
                              distributions available under a generalized optional form considered in the
                              aggregate are burdensome or complex, then replacing some of the actuarial
                              factors for the generalized optional form is presumed to eliminate section
                              411(d)(6)(B) protected benefits that create significant burdens or complexities
                              for the plan and its participants.  However, if the effect is merely to substitute
                              one set of actuarial factors for another set of actuarial factors, without
                              any reduction in the number of different actuarial factors or the complexity
                              of those factors, then the plan amendment does not satisfy the requirements
                              of this paragraph (e)(2) unless the change of actuarial factors is merely
                              to replace one or more of the plan’s actuarial factors for determining
                              optional forms of benefit with new actuarial factors that are more accurate
                              (e.g., reflecting more recent mortality experience or
                              more recent market rates of interest).
                           
                           (iii) Restrictions against creating burdens or complexities.
                               See paragraphs (a)(2)(iii) and (b)(1)(iii) of this section for general rules
                              applicable to multiple amendments.  In accordance with these rules, a plan
                              amendment does not eliminate a section 411(d)(6)(B) protected benefit that
                              creates burdens and complexities for a plan and its participants if, less
                              than 3 years earlier, a plan was previously amended to add another retirement-type
                              subsidy in order to facilitate the elimination of the original retirement-type
                              subsidy, even if the elimination of the other subsidy would not adversely
                              affect the rights of any plan participant in a more than de minimis manner
                              as provided in paragraph (e)(3) of this section.
                           
                           (3) Elimination of early retirement benefits or retirement-type
                                    subsidies that are de minimis—(i) Rules for retained
                                    optional forms of benefit under paragraph (c) of this section.
                               For purposes of paragraph (c) of this section, the elimination of an optional
                              form of benefit does not adversely affect the rights of any participant in
                              a more than de minimis manner if—
                           
                           (A) The retained optional form of benefit described in paragraph (c)
                              of this section has substantially the same annuity commencement date as the
                              optional form of benefit that is being eliminated, as described in paragraph
                              (e)(4) of this section; and
                           
                           (B) Either the actuarial present value of the benefit payable in the
                              optional form of benefit that is being eliminated does not exceed the actuarial
                              present value of the benefit payable in the retained optional form of benefit
                              by more than a de minimis amount, as described in paragraph
                              (e)(5) of this section, or the amendment satisfies the requirements of paragraph
                              (e)(6) of this section relating to a delayed effective date.
                           
                           (ii) Rules for core options under paragraph (d) of this section.
                               For purposes of paragraph (d) of this section, the elimination of an optional
                              form of benefit does not adversely affect the rights of any participant in
                              a more than de minimis manner if, with respect to each
                              of the core options—
                           
                           (A) The core option is available after the amendment with substantially
                              the same annuity commencement date as the optional form of benefit that is
                              being eliminated, as described in paragraph (e)(4) of this section; and
                           
                           (B) Either the actuarial present value of the benefit payable in the
                              optional form of benefit that is being eliminated does not exceed the actuarial
                              present value of the benefit payable under the core option by more than a de
                                    minimis amount, as described in paragraph (e)(5) of this section,
                              or the amendment satisfies the requirements of paragraph (e)(6) of this section.
                           
                           (4) Definition of substantially the same annuity starting
                                    dates.  For purposes of applying paragraphs (e)(3)(i)(A) and (ii)(A)
                              of this section, annuity starting dates are considered substantially the same
                              if they are within 6 months of each other.
                           
                           (5) Definition of de minimis difference in actuarial present
                                    value.  For purposes of applying paragraph (e)(3)(i)(B) and (ii)(B)
                              of this section, a difference in actuarial present value between the optional
                              form of benefit being eliminated and the retained optional form of benefit
                              or core option is not more than a de minimis amount if,
                              as of the date the amendment is adopted, the difference between the actuarial
                              present value of the eliminated optional form of benefit and the actuarial
                              present value of the retained optional form of benefit  or core option is
                              not more than the greater of—
                           
                           (i) 2% of the present value of the retirement-type subsidy (if any)
                              under the eliminated optional form of benefit prior to the amendment; or
                           
                           (ii) 1% of the greater of the participant’s compensation (as defined
                              in section 415(c)(3)) for the prior plan year or the participant’s average
                              compensation for his or her high 3 years (within the meaning of section 415(b)(1)(B)
                              and (b)(3)).
                           
                           (6) Delayed effective date—(i) General
                                    rule.  For purposes of applying paragraph (e)(3)(i)(B) and (ii)(B)
                              of this section, an amendment that eliminates an optional form of benefit
                              satisfies the requirements of this paragraph (e)(6) if the elimination of
                              the optional form of benefit is not applicable to any annuity commencement
                              date before the end of the expected transition period for that optional form
                              of benefit.
                           
                           (ii) Determination of expected transition period—(A) General
                                    rule.  The expected transition period for a plan amendment eliminating
                              an optional form of benefit is the period that begins when the amendment is
                              adopted and ends when it is reasonable to expect, with respect to a section
                              411(d)(6)(B) protected benefit (i.e., not taking into
                              account benefits that accrue in the future), that the form being eliminated
                              would be subsumed by another optional form of benefit after taking into account
                              expected future benefit accruals.
                           
                           (B) Determination of expected transition period using conservative
                                    actuarial assumptions.  The expected transition period for a plan
                              amendment eliminating an optional form of benefit must be determined in accordance
                              with actuarial assumptions that are reasonable at the time of the amendment
                              and that are conservative (i.e., reasonable actuarial
                              assumptions that are likely to result in the longest period of time until
                              the eliminated optional form of benefit would be subsumed).  For this purpose,
                              actuarial assumptions are not treated as conservative unless they include
                              assumptions that a participant’s compensation will not increase and
                              that future benefit accruals will not exceed accruals in recent periods.
                           
                           (C) Effect of subsequent amendments reducing future benefit
                                    accruals on the expected transition period.  If, during the expected
                              transition period for a plan amendment eliminating an optional form of benefit,
                              the plan is subsequently amended to reduce the rate of future benefit accrual
                              (or otherwise to lengthen the expected transition period), thus that subsequent
                              plan amendment must provide that the elimination of the optional form of benefit
                              is void or must provide for the effective date for elimination of the optional
                              form of benefit to be further extended to a new expected transition period
                              that satisfies this paragraph (e)(6) taking into account the subsequent amendment.
                           
                           (iii) Applicability of the delayed effective date rule limited
                                    to employees who continue to accrue benefits through the end of expected transition
                                    period.  An amendment eliminating an optional form of benefit under
                              this paragraph (e)(6) must be limited to participants who continue to accrue
                              benefits under the plan through the end of the expected transition period.
                               Thus, for example, the plan amendment may not apply to any participant who
                              has a severance from employment during the expected transition period.
                           
                           (iv) Special rule for section 204(h) notice.  See
                              §54.4980F-1(b), Q&A-8(c) of this chapter for a special rule relating
                              to this paragraph (e)(6).
                           
                           (f) Utilization test.  [Reserved].
                           
                           (g) Definitions and use of terms.  The definitions
                              in this paragraph (g) apply for purposes of this section.
                           
                           (1) Actuarial present value.  The term actuarial
                                    present value means actuarial present value (within the meaning
                              of §1.401(a)(4)-12) determined using reasonable actuarial assumptions.
                           
                           (2) Ancillary benefit.  The term ancillary
                                    benefit means—
                           
                           (i) A social security supplement under a defined benefit plan (other
                              than a QSUPP as defined in §1.401(a)(4)-12);
                           
                           (ii) A benefit payable under a defined benefit plan in the event of
                              disability (to the extent that the benefit exceeds the benefit otherwise payable),
                              but only if the total benefit payable in the event of disability does not
                              exceed the maximum qualified disability benefit, as defined in section 411(a)(9);
                           
                           (iii) A life insurance benefit;
                           (iv) A medical benefit described in section 401(h);
                           (v) A death benefit under a defined benefit plan other than a death
                              benefit which is a part of an optional form of benefit; or
                           
                           (vi) A plant shutdown benefit or other similar benefit in a defined
                              benefit plan that does not continue past retirement age and does not affect
                              the payment of the accrued benefit, but only to the extent that such plant
                              shutdown benefit, or other similar benefit (if any), is permitted in a qualified
                              pension plan (see §1.401-1(b)(1)(i)).
                           
                           (3)  Annuity commencement date.  The term annuity
                                    commencement date generally means the annuity starting date, except
                              that, in the case of a retroactive annuity starting date under section 417(a)(7), annuity
                                    commencement date means the date of the first payment of benefits
                              pursuant to a participant election of a retroactive annuity starting date,
                              as defined in §1.417(e)-1(b)(3)(iv).
                           
                           (4) Applicable amendment date.  The term applicable
                                    amendment date, with respect to a plan amendment, means the later
                              of the effective date of the amendment or the date the amendment is adopted.
                           
                           (5) Core options—(i) General rule.
                               With respect to a plan, the term core options means—
                           
                           (A) A straight life annuity generalized optional form under which the
                              participant is entitled to a level life annuity with no benefit payable after
                              the participant’s death;
                           
                           (B) A 75% joint and contingent annuity generalized optional form under
                              which the participant is entitled to a life annuity with a survivor annuity
                              for any individual designated by the participant (including a non-spousal
                              contingent annuitant) that is 75% of the amount payable during the participant’s
                              life (but see paragraph (d)(2)(v) of this section for a special rule relating
                              to the joint and contingent annuity core option);
                           
                           (C) A 10-year term certain and life annuity generalized optional form
                              under which the participant is entitled to a life annuity with a guarantee
                              that payments will continue to any person designated by the participant for
                              the remainder of a fixed period of 10 years if the participant dies before
                              the end of the 10-year period; and
                           
                           (D) The most valuable option for a participant with a short life expectancy
                              (as defined in paragraph (g)(5)(iii) of this section).
                           
                           (ii) Modification of core options to satisfy other requirements.
                               An annuity does not fail to be a core option (e.g.,
                              a joint and contingent annuity described in paragraph (g)(5)(i)(B) of this
                              section or a 10-year term certain and life annuity described in paragraph
                              (g)(5)(i)(C) of this section) as a result of differences to comply with applicable
                              law, such as limitations on death benefits to comply with the incidental benefit
                              requirement of §1.401-1(b)(1)(i) or on account of the spousal consent
                              rules of section 417.
                           
                           (iii) Most valuable option for a participant with a short
                                    life expectancy—(A) General definition.
                               Except as provided in paragraph (g)(5)(iii)(B) of this section, most
                                    valuable option for a participant with a short life expectancy means,
                              for an annuity starting date, the optional form of benefit that is reasonably
                              expected to result in payments that have the largest actuarial present value
                              in the case of a participant who dies shortly after the annuity starting date,
                              taking into account both payments due to the participant prior to the participant’s
                              death and any payments due after the participant’s death.  For this
                              purpose, a plan is permitted to assume that the spouse of the participant
                              is the same age as the participant.  In addition, a plan is permitted to assume
                              that the optional form of benefit that is the most valuable option for a participant
                              with a short life expectancy when the participant is age 701/2 also
                              is the most valuable option for a participant with a short life expectancy
                              at all older ages, and that the most valuable option for a participant with
                              a short life expectancy at age 55 is the most valuable option for a participant
                              with a short life expectancy at all younger ages.
                           
                           (B) Safe harbor hierarchy—(1)
                              A plan is permitted to treat a single-sum distribution option with an actuarial
                              present value that is not less than the actuarial present value of any optional
                              form of benefit eliminated by the plan amendment as the most valuable option
                              for a participant with a short life expectancy for all of a participant’s
                              annuity starting dates if such single-sum distribution option is available
                              at all such dates, without regard to whether the option was available before
                              the plan amendment.
                           
                           (2) If the plan before the amendment does not offer
                              a single-sum distribution option as described in paragraph (g)(5)(iii)(B)(1)
                              of this section, a plan is permitted to treat a joint and contingent annuity
                              with a continuation percentage that is at least 75% and that is at least as
                              great as the highest continuation percentage available before the amendment
                              as the most valuable option for a participant with a short life expectancy
                              for all of a participant’s annuity starting dates if such joint and
                              contingent annuity is available at all such dates, without regard to whether
                              the option was available before the plan amendment.
                           
                           (3) If the plan before the amendment offers neither
                              a single-sum distribution option as described in paragraph (g)(5)(iii)(B)(1)
                              of this section nor a joint and contingent annuity with a continuation percentage
                              as described in paragraph (g)(5)(iii)(B)(2) of this section,
                              a plan is permitted to treat a term certain and life annuity with a term certain
                              period no less than 15 years as the most valuable option for a participant
                              with a short life expectancy for each annuity starting date if such 15-year
                              term certain and life annuity is available at all annuity starting dates,
                              without regard to whether the option was available before the plan amendment.
                           
                           (6) Definitions of types of section 411(d)(6)(B) protected
                                    benefits—(i) Early retirement benefit.
                               The term early retirement benefit means the right, under
                              the terms of a plan, to commence distribution of a retirement-type benefit
                              at a particular date after severance from employment with the employer and
                              before normal retirement age.  Different early retirement benefits result
                              from differences in terms relating to timing.
                           
                           (ii) Optional form of benefit—(A)  In
                                    general.  The term optional form of benefit means
                              a distribution alternative (including the normal form of benefit) that is
                              available under the plan with respect to an accrued benefit or a distribution
                              alternative with respect to a retirement-type benefit.  Different optional
                              forms of benefit exist if a distribution alternative is not payable on substantially
                              the same terms as another distribution alternative.  The relevant terms include
                              all terms affecting the value of the optional form, such as the method of
                              benefit calculation and the actuarial factors or assumptions used to determine
                              the amount distributed.  Thus, for example, different optional forms of benefit
                              may result from differences in terms relating to the payment schedule, timing,
                              commencement, medium of distribution (e.g., in cash or
                              in kind), election rights, differences in eligibility requirements, or the
                              portion of the benefit to which the distribution alternative applies.  Likewise,
                              differences in the normal retirement ages of employees or in the form in which
                              the accrued benefit of employees is payable at normal retirement age under
                              a plan are taken into account in determining whether a distribution alternative
                              constitutes one or more optional forms of benefit.
                           
                           (B)  Death benefits.  If a death benefit is payable
                              after the annuity starting date for a specific optional form of benefit and
                              the same death benefit would not be provided if another optional form of benefit
                              were elected by a participant, then that death benefit is part of the specific
                              optional form of benefit and is thus protected under section 411(d)(6).  A
                              death benefit is not treated as part of a specific optional form of benefit
                              merely because the same benefit is not provided to a participant who has received
                              his or her entire accrued benefit prior to death.  For example, a $5,000 death
                              benefit that is payable to all participants except any participant who has
                              received his or her accrued benefit in a single-sum distribution is not part
                              of a specific optional form of benefit.
                           
                           (iii) Retirement-type benefit.  The term retirement-type
                                    benefit means—
                           
                           (A) The payment of a distribution alternative with respect to an accrued
                              benefit; or
                           
                           (B) The payment of any other benefit under a defined benefit plan (including
                              a QSUPP as defined in §1.401(a)(4)-12) that is permitted to be in a qualified
                              pension plan, continues after retirement, and is not an ancillary benefit. 
                           
                           (iv) Retirement-type subsidy.  The term retirement-type
                                    subsidy means the excess, if any, of the actuarial present value
                              of a retirement-type benefit over the actuarial present value of the accrued
                              benefit commencing at normal retirement age or at actual commencement date,
                              if later, with both such actuarial present values determined as of the date
                              the retirement-type benefit commences.  Examples of retirement-type subsidies
                              include a subsidized early retirement benefit and a subsidized qualified joint
                              and survivor annuity.
                           
                           (v) Subsidized early retirement benefit or early retirement
                                    subsidy.  The terms subsidized early retirement benefit or early
                                    retirement subsidy mean the right, under the terms of a plan, to
                              commence distribution of a retirement-type benefit at a particular date after
                              severance from employment with the employer and before normal retirement age
                              where the actuarial present value of the optional forms of benefit available
                              to the participant under the plan at that annuity starting date exceeds the
                              actuarial present value of the accrued benefit commencing at normal retirement
                              age (with such actuarial present values determined as of the annuity starting
                              date).  Thus, an early retirement subsidy is an early retirement benefit that
                              provides a retirement-type subsidy.
                           
                           (7)  Eliminate; elimination; reduce; reduction.
                               The terms eliminate or elimination when
                              used in connection with a section 411(d)(6)(B) protected benefit mean to eliminate
                              or the elimination of an optional form of benefit or an early retirement benefit
                              and to reduce or a reduction in a retirement-type subsidy.  The terms reduce or reduction when
                              used in connection with a retirement-type subsidy mean to reduce or a reduction
                              in the amount of the subsidy.  For purposes of this section, an elimination includes
                              a reduction and a reduction includes
                              an elimination.
                           
                           (8)  Generalized optional form.  The term generalized
                                    optional form means a group of optional forms of benefit that are
                              identical except for differences due to the actuarial factors that are used
                              to determine the amount of the distributions under those optional forms of
                              benefit and the annuity starting dates.
                           
                           (9)  Maximum QJSA explanation period.  The term maximum
                                    QJSA explanation period means the maximum number of days before
                              an annuity starting date for a qualified joint and survivor annuity for which
                              a written explanation relating to the qualified joint and survivor annuity
                              would satisfy the timing requirements of section 417(a)(3) and §1.417(e)-1(b)(3)(ii).
                           
                           (10) Other right and feature.  The term other
                                    right or feature has the meaning set forth at §1.401(a)(4)-4(e)(3)(ii).
                           
                           (11) Refund of employee contributions feature.
                               The term refund of employee contributions features means
                              a feature with respect to an optional form of benefit that provides for employee
                              contributions and interest thereon to be paid in a single sum at the annuity
                              starting date with the remainder to be paid in another form beginning on that
                              date.
                           
                           (12) Retirement; retirement age.  For purposes
                              of this section, the date of retirement means the annuity
                              starting date.  Thus, retirement age means a participant’s
                              age at the annuity starting date.
                           
                           (13) Retroactive annuity starting date feature.
                               The term retroactive annuity starting date feature means
                              a feature with respect to an optional form of benefit under which the annuity
                              starting date for the distribution occurs on or before the date the written
                              explanation required by section 417(a)(3) is provided to the participant. 
                           
                           (14) Section 411(d)(6) protected benefit.  The
                              term section 411(d)(6) protected benefit means the accrued
                              benefit of a participant as of the applicable amendment date described in
                              section 411(d)(6)(A) and any section 411(d)(6)(B) protected benefit.
                           
                           (15) Section 411(d)(6)(B) protected benefit.  The
                              term section 411(d)(6)(B) protected benefit means the
                              portion of an early retirement benefit, a retirement-type subsidy, or an optional
                              form of benefit attributable to benefits accrued before the applicable amendment
                              date.
                           
                           (16) Social security leveling feature.  The term social
                                    security leveling feature means a feature with respect to an optional
                              form of benefit commencing prior to a participant’s expected commencement
                              of social security benefits that provides for a temporary period of higher
                              payments which is designed to result in an approximately level amount of income
                              when the participant’s estimated old age benefits from Social Security
                              are taken into account.
                           
                           (h) Examples.  The following examples illustrate
                              the application of paragraphs (c) through (g) of this section:
                           
                           Example 1.  (i) Facts involving elimination
                                    of optional forms of benefit as redundant.  Plan C is a defined
                              benefit plan under which employees may elect to commence distributions at
                              any time after the later of termination of employment or attainment of age
                              55.  At each potential annuity commencement date, Plan C permits employees
                              to select, with spousal consent where required, a straight life annuity or
                              any of a number of actuarially equivalent alternative forms of payment, including
                              a straight life annuity with cost-of-living increases and a joint and contingent
                              annuity with the participant having the right to select any beneficiary and
                              any continuation percentage from 1% to 100%, subject to modification to the
                              extent necessary to satisfy the requirements of the incidental benefit requirement
                              of §1.401-1(b)(1)(i).  The amount of any alternative payment is determined
                              as the actuarial equivalent of the straight life annuity payable at the same
                              age using reasonable actuarial assumptions.  On June 2, 2006, Plan C is amended
                              to delete all continuation percentages for joint and contingent options other
                              than 25%, 50%, 75%, or 100%, effective with respect to annuity commencement
                              dates that are on or after January 1, 2007.
                           
                           (ii)  Conclusion—(A)  Categorization
                                    of family members under the redundancy rule.  The optional forms
                              of benefit described in paragraph (i) of this Example 1 are
                              members of 4 families: a straight life annuity; a straight life annuity with
                              cost-of-living increases; joint and contingent options with continuation percentages
                              of less than 50%; and joint and contingent options with continuation percentages
                              of 50% or more.  The amendment does not affect either of the first two families,
                              but affects the two families relating to joint and contingent options.
                           
                           (B)  Conclusion for elimination of optional forms of benefit
                                    as redundant.  The amendment satisfies the requirements of paragraph
                              (c) of this section.  First, the eliminated optional forms of benefit are
                              redundant with respect to the retained optional forms of benefit because each
                              eliminated joint and contingent annuity option with a continuation percentage
                              of less than 50% is redundant with respect to the 25% continuation option
                              and each eliminated joint and contingent annuity option with a continuation
                              percentage of 50% or higher is redundant with respect to any one of the retained
                              50%, 75%, or 100% continuation options.  In addition, to the extent that the
                              optional form of benefit that is being eliminated does not include a social
                              security leveling feature, return of employee contribution feature, or retroactive
                              annuity starting date feature, the retained optional form of benefit does
                              not include that feature.  Second, the amendment is not effective with respect
                              to annuity commencement dates before September 1, 2006, as required under
                              paragraph (c)(1)(ii) of this section.  Third, the plan amendment does not
                              eliminate any available core option, including the most valuable option for
                              a participant with a short life expectancy, treating a joint and contingent
                              annuity with a 100% continuation percentage as this optional form of benefit
                              pursuant to paragraph (g)(5)(iii)(B)(2) of this section.
                               Finally, the amendment need not satisfy the requirements of paragraph (e)
                              of this section because the retained optional forms of benefit are available
                              on the same annuity commencement dates and have the same actuarial present
                              value as the optional forms of benefit that are being eliminated.
                           
                           Example 2.  (i) Facts involving elimination
                                    of optional forms of benefit as redundant if additional restrictions are imposed.
                               The facts are the same as Example 1, except that the
                              plan amendment also restricts the class of beneficiaries that may be elected
                              under the 4 retained joint and contingent annuities to the employee’s
                              spouse.
                           
                           (ii) Conclusion.  The amendment fails to satisfy
                              the requirements of paragraph (c)(2)(i)(B) of this section because the retained
                              joint and contingent annuities have materially greater restrictions on the
                              beneficiary designation than did the eliminated joint and contingent annuities.
                               Thus, the joint and contingent annuities being eliminated are not redundant
                              with respect to the retained joint and contingent annuities.  In addition,
                              the amendment fails to satisfy the requirements of the core option rules in
                              paragraph (d) of this section because the amendment fails to be limited to
                              annuity commencement dates that are at least 4 years after the date the amendment
                              is adopted, the amendment fails to include the core option in paragraph (g)(5)(i)(B)
                              of this section because the participant does not have the right to designate
                              any beneficiary, and the amendment fails to include the core option described
                              in paragraph (g)(5)(i)(C) of this section because the plan does not provide
                              a 10-year term certain and life annuity.
                           
                           Example 3.  (i) Facts involving elimination
                                    of a social security leveling feature and a period certain annuity as redundant.
                               Plan D is a defined benefit plan under which participants may elect to commence
                              distributions in the following actuarially equivalent forms, with spousal
                              consent if applicable:  a straight life annuity; a 50%, 75%, or 100% joint
                              and contingent annuity; a 5-year, 10-year, or a 15-year term certain and life
                              annuity; and an installment refund annuity (i.e., an
                              optional form of benefit that provides a period certain, the duration of which
                              is based on the participant’s age), with the participant having the
                              right to select any beneficiary.  In addition, each annuity offered under
                              the plan, if payable to a participant who is less than age 65, is available
                              both with and without a social security leveling feature.  The social security
                              leveling feature provides for an assumed commencement of social security benefits
                              at any age selected by the participant between age 62 and 65.  Plan D is amended
                              on June 2, 2006, effective as of January 1, 2007, to eliminate the installment
                              refund form of benefit and to restrict the social security leveling feature
                              to an assumed social security commencement age of 65.
                           
                           (ii) Conclusion.  The amendment satisfies the requirements
                              of paragraph (c) of this section.  First, the installment refund annuity option
                              is redundant with respect to the 15-year certain and life annuity (except
                              for advanced ages where, because of shorter life expectancies, the installment
                              refund annuity option is redundant with respect to the 5-year certain and
                              life annuity and also redundant with respect to the 10-year certain and life
                              annuity).  Second, with respect to restricting the social security leveling
                              feature to an assumed social security commencement age of 65, under paragraph
                              (c)(3)(ii)(C) of this section, straight life annuities with social security
                              leveling features that have different social security commencement ages are
                              treated as members of the same family as straight life annuities without social
                              security leveling features.  To the extent an optional form of benefit that
                              is being eliminated includes a social security leveling feature, the retained
                              optional form of benefit must also include that feature, but it is permitted
                              to have a different assumed age for commencement of social security benefits.
                               Third, to the extent that the optional form of benefit that is being eliminated
                              does not include a social security leveling feature, a return of employee
                              contribution feature, or retroactive annuity starting date feature, the retained
                              optional form of benefit must not include that feature.  Fourth, the plan
                              amendment does not eliminate any available core option, including the most
                              valuable option for a participant with a short life expectancy, treating a
                              joint and contingent annuity with a 100% continuation percentage as this optional
                              form of benefit pursuant to paragraph (g)(5)(iii)(B)(2)
                              of this section.  Fifth, the amendment is not effective with respect to annuity
                              commencement dates before September 1, 2006, as required under paragraph (c)(1)(ii)
                              of this section.  The amendment need not satisfy the requirements of paragraph
                              (e) of this section because the retained optional forms of benefit are available
                              on the same annuity commencement dates and have the same actuarial present
                              value as the optional forms of benefit that are being eliminated.
                           
                           Example 4.  (i) Facts involving elimination
                                    of noncore options.  Employer N sponsors Plan E, a defined benefit
                              plan that permits every participant to elect payment in the following actuarially
                              equivalent optional forms of benefit (Plan E’s uniformly available options),
                              with spousal consent if applicable:  a straight life annuity; a 50%, 75%,
                              or 100% joint and contingent annuity with no restrictions on designation of
                              beneficiaries; and a 5-, 10-, or 15-year term certain and life annuity.  In
                              addition, each can be elected in conjunction with a social security leveling
                              feature, with the participant permitted to select a social security commencement
                              age from age 62 to age 67.  None of Plan E’s uniformly available options
                              include a single-sum distribution.  The plan has been in existence for over
                              30 years, during which time Employer N has acquired a large number of other
                              businesses, including merging over 20 defined benefit plans of acquired entities
                              into Plan E.  Many of the merged plans offered optional forms of benefit that
                              were not among Plan E’s uniformly available options, including some
                              plans funded through insurance products, often offering all of the insurance
                              annuities that the insurance carrier offers, and with some of the merged plans
                              offering single-sum distributions.  In particular, under the XYZ acquisition
                              that occurred in 1990, the XYZ acquired plan offered a single-sum distribution
                              option that was frozen at the time of the acquisition.  On April 1, 2006,
                              each single-sum distribution option applies to less than 25% of the XYZ participants’
                              accrued benefits.  Employer N has generally, but not uniformly, followed the
                              practice of limiting the optional forms of benefit for an acquired unit to
                              an employee’s service before the date of the merger, and has uniformly
                              followed this practice with respect to each of the early retirement subsidies
                              in the acquired unit’s plan.  As a result, as of April 1, 2007, Plan
                              E includes a large number of generalized optional forms which are not members
                              of families of optional forms of benefit identified in paragraph (c)(4) of
                              this section, but there are no participants who are entitled to any early
                              retirement subsidies because any subsidies have been subsumed by the actuarially
                              reduced accrued benefit.  Plan E is amended in April of 2007 to eliminate
                              all of the optional forms of benefit that Plan E offers other than Plan E’s
                              uniformly available options, except that the amendment does not eliminate
                              any single-sum distribution option except with respect to XYZ participants
                              and permits any commencement date that was permitted under Plan E before the
                              amendment.  Plan E also eliminates the single-sum distribution option for
                              XYZ participants.  Further, each of Plan E’s uniformly available options
                              has an actuarial present value that is not less than the actuarial present
                              value of any optional form of benefit offered before the amendment.  The amendment
                              is effective with respect to annuity commencement dates that are on or after
                              May 1, 2011.
                           
                           (ii) Conclusion.  The amendment satisfies the requirements
                              of paragraph (d) of this section.  First, Plan E, as amended, does not eliminate
                              any single-sum distribution option as provided in paragraph (d)(2)(iii) of
                              this section except for single-sum distribution options that apply to less
                              than 25% of a plan participant’s accrued benefit as of the date the
                              option is eliminated (May 1, 2011).  Second, Plan E, as amended, includes
                              each of the core options as defined in paragraph (g)(5) of this section, including
                              offering the most valuable option for a participant with a short life expectancy
                              (treating the 100% joint and contingent annuity as this benefit, under paragraph
                              (g)(5)(iii)(B)(2) of this section).  The 100% joint and
                              contingent annuity option (and not the grandfathered single-sum distribution
                              option) is the most valuable option for a participant with a short life expectancy
                              because the grandfathered single-sum distribution option is not available
                              with respect to a participant’s entire accrued benefit.  In addition,
                              as required under paragraph (d)(2) of this section, to the extent an optional
                              form of benefit that is being eliminated includes either a social security
                              leveling feature or a refund of employee contributions feature, at least one
                              of the core options is available with that feature and, to the extent that
                              the optional form of benefit that is being eliminated does not include a social
                              security leveling feature or a refund of employee contributions feature, each
                              of the core options is available without that feature.  Third, the amendment
                              is not effective with respect to annuity commencement dates that are less
                              than 4 years after the date the amendment is adopted.  Finally, the amendment
                              need not satisfy the requirements of paragraph (e) of this section because
                              the retained optional forms of benefit are available on the same annuity commencement
                              date and have the same actuarial present value as the optional forms of benefit
                              that are being eliminated.  The conclusion that the amendment satisfies the
                              requirements of paragraph (d) of this section assumes that no amendments are
                              made to change the core options before May 1, 2014.
                           
                           Example 5.  (i) Facts involving reductions
                                    in actuarial present value.  (A)  Plan F is a defined benefit plan
                              providing an accrued benefit of 1% of the average of a participant’s
                              highest 3 consecutive years’ pay times years of service, payable as
                              a straight life annuity beginning at the normal retirement age at age 65.
                               Plan F permits employees to elect to commence actuarially reduced distributions
                              at any time after the later of termination of employment or attainment of
                              age 55.  At each potential annuity commencement date, Plan F permits employees
                              to select, with spousal consent, either a straight life annuity, a joint and
                              contingent annuity with the participant having the right to select any beneficiary
                              and a continuation percentage of 50%, 66 2/3%, 75%, or 100%, or a 10-year
                              certain and life annuity with the participant having the right to select any
                              beneficiary, subject to modification to the extent necessary to satisfy the
                              requirements of the incidental benefit requirement of §1.401-1(b)(1)(i).
                               The amount of any joint and contingent annuity and the 10-year certain and
                              life annuity is determined as the actuarial equivalent of the straight life
                              annuity payable at the same age using reasonable actuarial assumptions.  The
                              plan covers employees at 4 divisions, one of which, Division X, was acquired
                              on January 1, 1999.  The plan provides for distributions before normal retirement
                              age to be actuarially reduced, but, if a participant retires after attainment
                              of age 55 and completion of 10 years of service, the applicable early retirement
                              reduction factor is 3% per year for the years between age 65 and 62 and 6%
                              per year for the ages from 62 to 55 for all employees at any division, except
                              for employees who were in Division X on January 1, 1999, for whom the early
                              retirement reduction factor for retirement after age 55 and 10 years of service
                              is 5% for each year before age 65.  On June 2, 2006, effective January 1,
                              2007, Plan F is amended to change the early retirement reduction factors for
                              all employees of Division X to be the same as for other employees, effective
                              with respect to annuity commencement dates that are on or after January 1,
                              2008, but only with respect to participants who are employees on or after
                              January 1, 2008, and only if Plan F continues accruals at the current rate
                              through January 1, 2008 (or the effective date of the change in reduction
                              factors is delayed to reflect the change in the accrual rate).  For purposes
                              of this Example 5, it is assumed that an actuarially
                              equivalent early retirement factor would have a reduction shown in column
                              4 of the following table, which compares the reduction factors for Division
                              X before and after the amendment:
                           
                           
                           (B)  On January 1, 2007, the employee with the largest number of years
                              of service is Employee E, who is age 54 and has 20 years of service.  For
                              2006, Employee E’s compensation is $80,000 and E’s highest 3 consecutive
                              years of pay on January 1, 2007 is $75,000.  Employee E’s accrued benefit
                              as of the January 1, 2007 effective date of the amendment is a life annuity
                              of $15,000 per year at normal retirement age (1% times $75,000 times 20 years
                              of service) and E’s early retirement benefit commencing at age 55 has
                              a present value of $91,397 as of January 1, 2007.  It is assumed for purposes
                              of this example that the longest expected transition period for any active
                              employee does not exceed 5 months (20 years and 5 months, times 1% times 49%
                              exceeds 20 years times 1% times 50%).  Finally, it is assumed for purposes
                              of this example that the amendment reduces optional forms of benefit which
                              are burdensome or complex.
                           
                           (ii) Conclusion concerning application of section 411(d)(6)(B).
                               The amendment reducing the early retirement factors has the effect of eliminating
                              the existing optional forms of benefit (where the amount of the benefit is
                              based on preamendment early retirement factors in any case where the new factors
                              result in a smaller amount payable) and adding new optional forms of benefit
                              (where the amount of benefit is based on the different early retirement factors).
                               Accordingly, the elimination must satisfy the requirements of paragraph (c)
                              or (d) of this section if the amount payable at any date is less than would
                              have been payable under the plan before the amendment.
                           
                           (iii) Conclusion concerning application of redundancy rules.
                               The amendment satisfies the requirements of paragraph (c)(1)(i) and (ii)
                              of this section (see paragraphs (iv) through (vi) of this Example
                                    5 below for the requirements of paragraph (c)(1)(iii) of this section).
                               First, with respect to each eliminated optional form of benefit (i.e.,
                              with respect to each optional form of benefit with the Old Division X Factor),
                              after the amendment there is a retained optional form of benefit that is in
                              the same family of optional forms of benefit (i.e., the
                              optional form of benefit with the New Factor).  Second, the amendment is not
                              effective with respect to annuity commencement dates that are less than the
                              time period required under paragraph (c)(1)(ii) of this section.  Third, to
                              the extent that the plan amendment eliminates the most valuable option for
                              a participant with a short life expectancy, the retained optional form of
                              benefit is identical except for differences in actuarial factors.
                           
                           (iv) Conclusion concerning application of the requirements
                                    under paragraph (e) of this section.  The plan amendment must satisfy
                              the requirements of paragraph (e) of this section because, as of the December
                              2, 2006 adoption date, the actuarial present value of the early retirement
                              subsidy is less than the actuarial present value of the early retirement subsidy
                              being eliminated.  The plan amendment satisfies the requirements under paragraph
                              (e)(1)(i) and (2) of this section because the amendment eliminates optional
                              forms of benefit that create significant burdens or complexities for the plan
                              and its participants.  See below for the de minimis requirement
                              under paragraph (e)(1)(ii) and (3) of this section.
                           
                           (v) Conclusion concerning application of de minimis rules
                                    under paragraph (e)(5) of this section.  In order to satisfy the
                              requirements under paragraph (e)(1)(ii) and (3) of this section, the amendment
                              must satisfy the requirements of either paragraph (e)(5) or paragraph (e)(6)
                              of this section.  The amendment does not satisfy the requirements of paragraph
                              (e)(5) of this section because the reduction in the actuarial present value
                              is more than a de minimis amount under paragraph (e)(5)
                              of this section.  For example, for Employee E, the amount of the joint and
                              contingent annuity payable at age 55 is reduced from $7,500 (50% of $15,000)
                              to $7,350 (49% of $15,000) and the reduction in present value as a result
                              of the amendment is $1,828 ($91,397 - $89,569).  In this case, the retirement-type
                              subsidy at age 55 is the excess of the present value of the 50% early retirement
                              benefit over the present value of the deferred payment of the accrued benefit,
                              or $13,921 ($97,269 - $83,348) and the present value at age 54 of the retirement-type
                              subsidy is $13,081.  The reduction in present value is more than the greater
                              of 2% of the present value of the retirement-type subsidy and 1% of E’s
                              compensation because the reduction in present value exceeds $800 (the greater
                              of $262, which is 2% of the present value of the retirement-type subsidy for
                              the benefit being eliminated, and $800, which is 1% of E’s compensation
                              of $80,000).
                           
                           (vi) Conclusion involving application of de minimis rules
                                    under paragraph (e)(6) of this section relating to expected transition period.
                               The amendment satisfies the requirements of paragraph (e)(6) of this section
                              and, thus, satisfies the requirements of paragraph (c) of this section, including
                              the requirement in paragraph (c)(1)(iii) of this section that paragraph (e)
                              of this section be satisfied.  First, as assumed under the facts above, the
                              amendment reduces optional forms of benefit that are burdensome or complex.
                               Second, the plan amendment is not effective for annuity commencement dates
                              before January 1, 2008, and that date is not earlier than the longest expected
                              transition period for any participant in Plan F on the date of the amendment.
                               Third, the amendment does not apply to any participant who has a severance
                              from employment during the transition period.  If, however, a later plan amendment
                              reduces accruals under Plan F, the initial plan amendment will no longer satisfy
                              the requirements of paragraph (e)(6) of this section (and must be voided)
                              unless, as part of the later amendment, the expected transition period is
                              extended to reflect the reduction in accruals under Plan F.
                           
                           (i)  [RESERVED].
                           (j) Effective dates—(1) General
                                    effective date.  Except as otherwise provided in this paragraph
                              (j), the rules of this section apply to amendments adopted on or after August
                              12, 2005.
                           
                           (2) Effective date for rules relating to contingent event
                                    benefits.  Paragraph (b)(1)(ii) of this section applies to amendments
                              adopted after December 31, 2005.
