    OPINION OF THE COURT
    AMBRO, Circuit Judge
    2
    Congress changed the applicable interest rate for the
    present-value calculation of pension plans’ lump-sum payments
    to retirees. Hercules Inc. later amended its pension plan to
    match the changed interest rate, but that amendment resulted in
    a lower lump-sum payment to Charles Stepnowski, who retired
    several months after the amendment. To determine whether
    Hercules’ amendment was valid, we decide whether the
    Commissioner of the Internal Revenue Service extended the
    deadline for this amendment. We hold that the Commissioner
    did so, and that Hercules’ amendment was timely and valid. We
    therefore affirm.
    I. Factual Background and Procedural History
    Stepnowski worked at Hercules from 1973 to December
    2002. He participated in Hercules’ retirement plan, which
    allows participants to take a lump-sum payment upon
    retirement. This payment is the present-value equivalent of 51%
    of the retiree’s expected lifetime monthly pension benefits.
    Pension Plan of Hercules Inc., sched. B., art. VII, § D.1. The
    present-value amount is calculated using the federally prescribed
    mortality table and a specified interest rate. 
    Id. § D.4.
    Hercules has a defined-benefit plan under the Employee
    Retirement Income Security Act of 1974, 29 U.S.C. § 1001 et
    seq. It was established in 1913 and uses the calendar year as its
    plan year. Hercules made amendments to the plan in October
    3
    2001.1
    The amendments to Hercules’ plan changed the interest
    rate used to calculate lump-sum payments. For payments made
    on or after January 1, 2002, the present-value amount is
    calculated using the interest rate on 30-year Treasury securities.
    Pension Plan, sched. B., art. VII, § D.4.a(2). The Treasury rate
    took the place of the interest rate published by the Pension
    Benefit Guaranty Corporation (PBGC).2
    Interest rates bear an inverse relationship to present-value
    amounts; a higher interest rate results in a lower present-value
    1
    This statement of the facts is contested by the parties.
    Hercules claims that the plan was amended in October 2001.
    Stepnowski, on the other hand, argues that it was amended as of
    January 28, 2002. Hercules’ Finance Committee passed a
    resolution amending the plan in October 2001, and Hercules’
    Board of Directors appears to have confirmed the resolution in
    January 2002. The Tax Court stated that Hercules “executed”
    the amendments in January 2002. Stepnowski v. Comm’r, 
    124 T.C. 198
    , 200 (2005). In any event, the difference in dates is
    immaterial to our conclusion in this case.
    2
    Under the amendment, the plan calculated the present-value
    amount for payments made between January 1, 2000, and
    January 1, 2002, using both the Treasury rate and the PBGC
    rate, and the retiree got the higher of the two amounts that result.
    Pension Plan, sched. B, art. VII, § D.4.b. Stepnowski, however,
    retired after January 2002.

    payment, and vice versa.3 The Treasury rate has historically
    been higher than the PBGC rate, so—because he retired after
    January 2002 (i.e., after the amendment)—Stepnowski’s lump-
    sum payment was lower than it would have been had Hercules
    kept the PBGC rate.4
    In February 2002, Hercules requested a determination
    from the Commissioner that its pension plan met all of the
    statutory qualification requirements.     In March 2002,
    Stepnowski sent the Commissioner a letter contending that the
    amendment precluded the Hercules plan from so qualifying. In
    March 2003, the Commissioner issued Hercules a favorable
    determination letter on the plan. Stepnowski then filed a
    petition in the United States Tax Court for a declaratory
    judgment that the Hercules plan was not qualified.
    The Tax Court held in favor of Hercules and the
    Commissioner, Stepnowski v. Comm’r, 
    124 T.C. 198
    , 220
    3
    This is so because the typical present-value formula involves
    division by the interest rate. Thus, as the interest rate gets
    higher, the numerator is divided by a larger number, resulting in
    a lower present value.
    4
    The parties estimate that Stepnowksi got $25,000 less
    because of the plan amendment.
    5
    (2005), and Stepnowski appeals.5
    II. Discussion
    A. Statutory and regulatory background
    Section 401(a) of the Internal Revenue Code describes
    the qualification requirements for pension plans. (Only
    qualified plans are tax exempt under I.R.C. § 501(a).) One of
    the requirements in § 401(a) is that, “except as provided in
    section 417,” the plan must pay out a vested participant’s
    accrued benefit “in the form of a qualified joint and survivor
    annuity.” I.R.C. § 401(a)(11)(A). Section 417 allows plan
    participants to waive these annuity payments in favor of a “cash-
    out”—that is, a lump-sum payment of the participants’ annuity
    benefits. See 
    id. § 417(a).
    Plan participants can therefore choose to take a lump-sum
    cash-out payment of the present value of their annuity, and
    § 417(e) governs the determination of that present-value
    amount. Specifically, § 417(e)(3)(A)(i) provides that the present
    value of a participant’s benefits “shall not be less than the
    5
    The Tax Court had jurisdiction under I.R.C. § 7476(a).
    We have appellate jurisdiction under I.R.C. § 7482(a).
    “We review the Tax Court’s legal determinations de
    novo, but we do not disturb its factual findings unless they are
    clearly erroneous.” Lattera v. Comm’r, 
    437 F.3d 399
    , 401 (3d
    Cir. 2006).
    6
    present value calculated by using the applicable mortality table
    and the applicable interest rate.”
    The “applicable interest rate” is a statutorily defined
    term. Before 1994, it meant the PBGC interest rate. Tax
    Reform Act of 1986, Pub. L. No. 99-514, § 1139(b), 100 Stat.
    2085, 2487. In 1994, Congress changed the definition in
    § 417(e)(3)(A)(ii)(II); it now means “the annual rate of interest
    on 30-year Treasury securities.” (The change was made as part
    of the Retirement Protection Act of 1994, which was itself part
    of the Uruguay Round Agreements Act. Pub. L. No. 103-465,
    tit. VII, subtit. F, § 767(a)(2), 108 Stat. 4809, 5038.)
    Elsewhere in the Code lurks § 411, which controls
    vesting standards; a plan cannot be qualified unless it satisfies
    this section. I.R.C. §§ 401(a)(7), 411(a). Specifically,
    § 411(d)(6)—known as the “anti-cutback provision”—blocks
    plan amendments that decrease participants’ accrued benefits.
    See 
    id. § 411(d)(6)(A);
    see also 
    id. § 411(d)(6)(B)
    (“[A] plan
    amendment which has the effect of . . . eliminating or reducing
    an early retirement benefit . . . with respect to benefits
    attributable to service before the amendment shall be treated as
    reducing accrued benefits.”).
    As noted, because the Treasury interest rate is generally
    higher than the PBGC rate, the normal result is a lower lump-
    sum payout (as happened here). Once the Retirement Protection
    Act changed the statutory rate, plan amendments following that
    7
    change could have been in danger of triggering the anti-cutback
    provision. Congress accordingly provided that “[a] participant’s
    accrued benefit shall not be considered to be reduced in
    violation of section 411(d)(6) . . . merely because . . . the benefit
    is determined in accordance with section 417(e)(3)(A) . . . , as
    amended by this Act.” Retirement Protection Act § 767(d), 108
    Stat. at 5040. The Department of the Treasury followed suit,
    providing that plan amendments replacing the PBGC rate with
    the Treasury rate were not cutbacks. Treas. Reg. § 1.417(e)-
    1(d)(10)(iv).6
    B. Does Treasury Regulation § 1.417(e)-1(d)(10)(i)
    contain an amendment deadline?
    Stepnowski’s unhappiness with the Treasury rate, as
    compared to the PBGC rate, is ultimately due to an act of
    Congress. He cannot complain that Hercules amended its plan
    to match the statutory interest rate, so he is forced to argue about
    when Hercules amended the plan. Stepnowski concedes that
    Hercules could have amended the plan without penalty on or
    before December 31, 1999, but he claims that the Treasury
    6
    This Regulation contains two conditions: First, the plan
    amendment has to replace the PBGC rate. Treas. Reg.
    § 1.417(e)-1(d)(10)(iv)(A). Second, the replacement rate has to
    be no higher than the Treasury rate, as calculated at certain
    times. 
    Id. § 1.417(e)-1(d)(10)(iv)(B).
    We agree with the Tax
    Court that Hercules’ plan amendment satisfied both of these
    conditions. See Stepnowski, 
    124 T.C. 210
    –11.
    8
    Regulations imposed that date as a deadline on such interest-rate
    amendments and that it was not extended.
    The Regulation at issue is Treas. Reg. § 1.417(e)-
    1(d)(10)(i), which provides that a prospective plan amendment
    that “changes the interest rate or the mortality assumptions used
    for the [present-value calculation] merely to eliminate use of the
    [PBGC] interest rate . . . , or the applicable mortality table, with
    respect to a distribution form described in paragraph (d)(6) of
    this section,” is not a cutback if it is adopted by December 31,
    1999.
    Stepnowski therefore argues that paragraph (d)(10)(i)
    requires interest-rate amendments like Hercules’ to be in place
    on or before December 31, 1999. The Commissioner
    argues—and the Tax Court held—that the December 1999
    deadline did not apply to the Hercules amendment. Both
    parties’ arguments turn on whether the phrase “with respect to
    a distribution form described in paragraph (d)(6) of this section”
    modifies “mortality table” alone or both “interest rate” and
    “mortality table.” The distribution form described in paragraph
    (d)(6) is a nondecreasing annual benefit—in other words, not a
    lump-sum payment like in Hercules’ plan. Thus, if the phrase
    modifies both “mortality table” and “interest rate,” this
    provision does not apply to amendments like Hercules’.
    The debate is between the last-antecedent rule of
    construction and its grammatical corollary. The last-antecedent
    9
    rule generally holds “that qualifying words, phrases, and clauses
    are to be applied to the words or phrase immediately preceding
    and not to others more remote.” United States v. Hodge, 
    321 F.3d 429
    , 436 (3d Cir. 2003) (internal quotation marks omitted).
    The corollary rule of grammar generally states that, where there
    is a comma before a modifying phrase, that phrase modifies all
    of the items in a series and not just the immediately preceding
    item. See, e.g., Elliot Coal Mining Co. v. Dir., 
    17 F.3d 616
    , 630
    (3d Cir. 1994) (“Th[e] use of a comma to set off a modifying
    phrase from other clauses indicates that the qualifying language
    is to be applied to all of the previous phrases and not merely the
    immediately preceding phrase.”); Nat’l Sur. Corp. v. Midland
    Bank, 
    551 F.2d 21
    , 34 (3d Cir. 1977); see also Kahn Lucas
    Lancaster, Inc. v. Lark Int’l Ltd., 
    186 F.3d 210
    , 215, 216 n.1 (2d
    Cir. 1999), abrogated in part on other grounds by Sarhank
    Group v. Oracle Corp., 
    404 F.3d 657
    , 660 n.2 (2d Cir. 2005);
    Bingham, Ltd. v. United States, 
    724 F.2d 921
    , 925 n.3 (11th Cir.
    1984).7
    7
    Under the last-antecedent rule of construction, therefore, the
    series “A or B with respect to C” contains two items: (1) “A”
    and (2) “B with respect to C.” On the other hand, under the rule
    of grammar the series “A or B, with respect to C” contains these
    two items: (1) “A with respect to C” and (2) “B with respect to
    C.” See Kahn 
    Lucas, 186 F.3d at 216
    n.1.
    Compare the Fifth Amendment of the Constitution, which
    provides that no person shall “be deprived of life, liberty, or
    property, without due process of law.” The comma before the
    phrase “without due process of law” indicates that the phrase
    10
    But neither of these aids in construction is dispositive;
    they serve only as guides. Moreover, the only other sentence in
    paragraph (d)(10)(i) fails to use this grammatical
    construction—in a situation where the modifying phrase almost
    certainly applies to all three elements in a series.8 Our
    confidence in paragraph (d)(10)(i)’s correct comma placement
    is thereby diminished. Thus we express no opinion on whether
    the deadline applied to Hercules. But our subsequent analysis
    makes clear that, even if there were a deadline imposed, the
    Commissioner extended it. So the question of whether there
    was a deadline need not be answered here.
    C.   If there was a deadline for interest-rate
    amendments, was it extended?
    For this analysis, we assume without deciding that a
    modifies “life,” “liberty,” and “property.”        This obviously
    follows the grammatical rule.
    8
    That sentence refers to a “plan amendment that changes [1]
    the interest rate, [2] the time for determining the interest rate, or
    [3] the mortality assumptions used for the purposes described in
    paragraph (d)(1) . . . .” Treas. Reg. § 1.417(e)-1(d)(10)(i)
    (emphasis added). There is no comma before the italicized
    phrase, but it appears that phrase is meant to modify all three
    items in the series. For example, paragraph (d)(1) discusses the
    present-value calculation, including the “applicable interest rate”
    and the “applicable mortality table.”
    11
    deadline was imposed for plan amendments replacing the PBGC
    rate with the Treasury rate. We thus face two questions. First,
    did the Commissioner extend that deadline in Rev. Proc. 99-23?
    Second, did Rev. Proc. 99-23 meet the statutory and regulatory
    requirements for extending the deadline?
    1. Did Revenue Procedure 99-23 extend the deadline
    for interest-rate amendments?
    The Commissioner extended deadlines for certain plan
    amendments in three different Revenue Procedures. The first
    Revenue Procedure, issued in 1999, listed several kinds of plan
    amendments and extended the deadline for making those
    amendments. The second and third—issued in 2000 and 2001,
    respectively—extended further the 1999 extension. We will
    work backward to the 1999 Revenue Procedure—the 2000 and
    2001 Revenue Procedures add little to our analysis here, as they
    simply extended the 1999 extension.
    The three Revenue Procedures deal with, among other
    things, plan amendments following GUST changes. GUST is an
    acronym for a list of several laws,9 but what is important here is
    9
    The laws listed in the 1999 Revenue Procedure include the
    Uruguay Round Agreements Act, the Uniformed Services
    Employment and Reemployment Rights Act of 1994, the Small
    Business Job Protection Act of 1996, the Taxpayer Relief Act of
    1997, and the Internal Revenue Service Restructuring and
    Reform Act of 1998. Rev. Proc. 99-23 § 2.01, 1999-16 I.R.B.
    12
    that GUST includes the Uruguay Round Agreements Act (which
    includes the Retirement Protection Act and the Treasury interest
    rate). Rev. Proc. 2000-27 § 1.02, 2000-26 I.R.B. 1272.
    In Rev. Proc. 2000-27, the Commissioner extended the
    deadline for “all GUST plan amendments, including all those
    specifically enumerated in Rev. Proc. 99-23,” to January 1,
    2001. 
    Id. §§ 4.01–.02.
    Revenue Procedure 2001-55 extended
    to February 28, 2002, the deadline for “all GUST plan
    amendments, including all those plan amendments specifically
    enumerated in Rev. Proc. 99-23.” Rev. Proc. 2001-55 § 3.01,
    2001-49 I.R.B. 552. Thus, whether Hercules had until February
    28, 2002, to adopt its amendment depends on whether its plan
    amendment was covered by Rev. Proc. 99-23. We now move to
    that inquiry.
    Revenue Procedure 99-23 extended to January 1, 2000,
    “the remedial amendment period under § 401(b) of the Code for
    amending plans that are qualified under
    § 401(a) . . . for . . . recent changes in the law.” Rev. Proc. 99-
    23 § 1.01, 1999-16 I.R.B. 5. The Revenue Procedure noted, in
    its Purpose section, that it extended the time allowed for plans
    to adopt the Treasury interest rate for purposes of present-value
    calculations. See 
    id. § 1.03.
    And in its Background section, it
    mentioned the Retirement Protection Act’s replacing the PBGC
    interest rate with the Treasury interest rate. 
    Id. §§ 2.07–.08.
    5.
    13
    Section 3.06 of Rev. Proc. 99-23 is the key. We quote it
    in full:
    Finally, the extension of the remedial
    amendment period also applies to the time for
    adopting amendments of defined benefit plans to
    provide that benefits will be determined in
    accordance with the applicable interest rate rules
    and applicable mortality table rules of
    § 1.417(e)-1(d). Thus, such a plan amendment
    may be adopted at any time up to the last day of
    the extended remedial amendment period,
    provided the amendment is made effective for
    distributions with annuity starting dates occurring
    in plan years beginning after December 31, 1999.
    However, pursuant to the Commissioner’s
    authority in § 1.401(b)-1T(c)(3), if such a plan
    amendment is adopted after the last day of the last
    plan year beginning before January 1, 2000, the
    amendment must provide that, with respect to
    distributions with annuity starting dates that are
    after the last day of that plan year but before the
    date of adoption of the amendment, the
    distribution will be the greater of the amount that
    would be determined under the plan without
    regard to the amendment and the amount
    determined under the plan with regard to the
    amendment.
    14
    
    Id. § 3.06.
    In English, section 3.06 says this: This Revenue
    Procedure applies to amendments that replace the PBGC interest
    rate with the Treasury interest rate. Thus, those amendments
    can be made until January 1, 2000, as long as they are made
    effective for payments made on or after January 1, 2000. But if
    such an amendment is adopted after January 1, 2000, it cannot
    take effect retroactively. For the period between January 1,
    2000, and the amendment adoption date, the plan must instead
    pay participants the greater of either (a) the amount due under
    the PBGC rate or (b) the amount due under the Treasury rate.
    As the plain-English translation makes clear, Rev. Proc.
    99-23 by its terms applied to the Hercules amendment. (It also
    makes clear that Hercules followed the Revenue Procedure’s
    anti-retroactivity rules in the amended plan; as noted in footnote
    2 above, Hercules gave participants the higher sum resulting
    from the PBGC- or Treasury-rate calculations until January
    2002.)
    Now we must determine whether Rev. Proc. 99-23 met
    the statutory and regulatory requirements for extending plan-
    amendment deadlines. If so, Rev. Proc. 99-23 and the
    subsequent Revenue Procedures extended the deadline for
    adopting the Treasury rate to February 28, 2002—and Hercules’
    amendment was adopted before that deadline. We address that
    question next.
    15
    2. Did the Revenue Procedures meet the statutory and
    regulatory requirements to extend the deadline?
    Section 401(b) of the Code allows plans to qualify under
    § 401(a) via retroactive10 amendment. The section basically
    provides that, if a plan is not effective in a given period, a
    retroactive, remedial amendment can make it effective for that
    period. See I.R.C. § 401(b). The Code authorizes the Secretary
    of the Treasury to set this remedial amendment period.11 See 
    id. Accordingly, Treas.
    Reg. § 1.401(b)-1 further defines the
    Secretary’s authority under § 401(b). The general rule is that a
    plan that does not satisfy § 401(a)’s requirements on any given
    day “shall be considered to have satisfied such requirements on
    such date if, on or before the last day of the remedial
    amendment period . . . with respect to such disqualifying
    provision,” the plan is amended to meet all of those
    10
    To dispel any confusion about section 1’s discussion of
    “anti-retroactivity rules” and section 2’s discussion of
    retroactivity, we note briefly that the anti-retroactivity rules set
    forth in Rev. Proc. 99-23 § 3.06 were simply limits on the
    retroactivity of interest-rate amendments. The Commissioner is
    empowered to impose limitations on retroactivity under Treas.
    Reg. § 1.401(b)-1(c)(3), and he did so in section 3.06.
    11
    A remedial amendment period may also be extended. The
    Commissioner has the authority to extend any remedial
    amendment period at his discretion.

    requirements by the end of the remedial amendment period, and
    those amendments are made retroactive to the beginning of the
    period. Treas. Reg. § 1.401(b)-1(a) (emphasis added). Thus, to
    take advantage of a retroactive amendment period, a plan must
    amend a “disqualifying provision.”
    In paragraph (b)(3), the Secretary grants the
    Commissioner authority to designate a “disqualifying
    provision.” This paragraph reads:
    A [disqualifying provision is a] plan
    provision designated by the Commissioner, at the
    Commissioner’s discretion, as a disqualifying
    provision that either—
    (i) Results in the failure of
    the plan to satisfy the qualification
    requirements of the Internal
    Revenue Code by reason of a
    change in those requirements; or
    (ii) Is integral to a
    qualification requirement of the
    Internal Revenue Code that has
    been changed.
    17
    
    Id. § 1.401(b)-1(b)(3).12
    Stepnowski concedes that section 3.06 of Rev. Proc. 99-
    23 complies with the Commissioner’s discretionary designation
    requirements. His argument is therefore that the Commissioner
    could not extend the remedial amendment period for interest-
    rate amendments because Hercules’ plan paid larger payments
    before it was amended. That is, Hercules did not need to amend
    the plan to satisfy the Retirement Protection Act because it was
    already paying more than the Act’s required minimum. The
    Hercules plan was qualified under § 401(a) because it used the
    PBGC interest rate, Stepnowski argues, so this more favorable
    interest rate to him could not be a “disqualifying provision.”
    Stepnowski’s argument fails because paragraph (b)(3) is
    written in the disjunctive. A “disqualifying provision” need not
    cause a plan to fail under § 401—although that is one definition
    of a “disqualifying provision” under Treas. Reg. § 1.401(b)-
    1(b)(3)(i). It can also be something that is simply “integral to a
    qualification requirement of the Internal Revenue Code that has
    been changed.” 
    Id. § 1.401(b)-1(b)(3)(ii).
    That is the issue
    before us; we address it in three brief points.
    12
    The Commissioner can only make such a designation in
    “revenue rulings, notices, and other guidance published in the
    Internal Revenue Bulletin.” Treas. Reg. § 1.401(b)-1(c)(2). The
    three Revenue Procedures at issue were published in the Internal
    Revenue Bulletin.
    18
    First, the present-value provision is a “qualification
    requirement of the Internal Revenue Code.” Section 401(a)
    describes the qualification requirements and refers to § 417 for
    provisions under which plan participants may choose lump-sum
    payments. I.R.C. § 401(a)(11)(F). Section 417(e)(3) in turn
    requires plans to use a minimum present-value calculation for
    such payments.
    Second, the interest-rate provision is “integral” to the
    present-value provision. Section 417(e)(3)(A)(i) sets minimum
    requirements for present-value calculations, stating that “the
    present value shall not be less than the present value calculated
    by using the applicable mortality table and the applicable
    interest rate.” And § 417(e)(3)(A)(ii)(II) defines the “applicable
    interest rate.” What is integral is something that is “essential to
    completeness” or is “serving to form a whole.” Webster’s Third
    New International Dictionary 1173 (Philip Babcock Gove ed.,
    1971). The “applicable interest rate” is essential to the present-
    value calculation and therefore, by definition, integral.
    Third, the interest-rate provision “has been changed.”
    Congress replaced the PBGC rate in 1994, making the 30-year
    Treasury interest rate the “applicable interest rate.” Retirement
    Protection Act § 767(a)(2), 108 Stat. at 5038.
    The only remaining question is whether the
    Commissioner implicitly designated the interest-rate provision
    19
    as a disqualifying provision in Rev. Proc. 99-23.13 We hold that
    he did for three reasons.
    First, the Commissioner cannot extend a remedial
    amendment period for something that he did not designate as a
    disqualifying provision. See Treas. Reg. § 1.401(b)-1(a)
    (discussing a “remedial amendment period . . . with respect to
    [a] disqualifying provision”).      Thus, the fact that the
    Commissioner extended the remedial amendment period for
    interest-rate amendments implies that he designated interest-rate
    provisions as “disqualifying provisions.”
    Second, the Commissioner expressly referred to his
    designation authority in requiring that the Treasury rate could
    not be imposed retroactively if adopted after January 1, 2000.
    The Revenue Procedure referred to “the Commissioner’s
    authority in § 1.401(b)-1T(c)(3)” in setting out this requirement.
    Rev. Proc. 99-23 § 3.06. Section 1.401(b)-1T(c)(3) in the
    temporary regulations—now found in Treas. Reg. § 1.401(b)-
    1(c)(3)—allowed the Commissioner to impose additional rules
    on provisions designated as “disqualifying provisions.”
    13
    Although Stepnowski points to section 4 of Rev. Proc. 99-
    23 as an example of an explicit designation of an integral
    provision, see Rev. Proc. 99-23 § 4 (“Designation of plan
    provisions integral to § 415(e) as disqualifying provisions”
    (capitalization altered)), the Commissioner can designate
    “disqualifying provisions” implicitly as well—and did so here
    in section 3.06.
    20
    Remedial Amendment Period, 62 Fed. Reg. 41272, 41274 (Aug.
    1, 1997) (codified at Treas. Reg. § 1.401(b)-1(c)(3)).
    Third, and most importantly, the Commissioner in the
    2000 Revenue Procedure recognized that all plan provisions
    “integral to a qualification requirement changed by GUST are
    disqualifying provisions under § 1.401(b)-1(b) of the
    regulations.” Rev. Proc. 2000-27 § 4.02. Because the GUST
    plan amendments included the amendments “specifically
    enumerated in Rev. Proc. 99-23,” 
    id., Rev. Proc.
    99-23
    designated the interest-rate provision as a “disqualifying
    provision.” Therefore, even if Rev. Proc. 99-23 did not
    explicitly designate the interest-rate provision as a
    “disqualifying provision,” Rev. Proc. 2000-27 did, so Hercules’
    amendment still fell within the deadline extended by the
    Commissioner.
    The Commissioner—by expressly referring to his
    designation powers and by extending a remedial amendment
    period for interest-rate amendments—designated the interest-
    rate plan provision as a “disqualifying provision” under Treas.
    Reg. § 1.401(b)-1(b)(3) and I.R.C. § 401(b).
    *****
    We hold that the Commissioner extended—until
    February 28, 2002—the deadline for plans to amend their
    present-value calculations to switch from using the PBGC rate
    21
    to using the 30-year Treasury rate. Because Hercules’ plan was
    amended to adopt the Treasury rate before February 28, 2002,
    its plan amendment was not a cutback prohibited by § 411(d)(6).
    We therefore affirm the Tax Court’s decision.
