    29 U.S.C. § 1001

    arguing, inter alia, that defendant-appellant Colgate-Palmolive Co. miscalculated
    residual annuities based on an erroneous interpretation of its retirement income

    residual annuities, thereby working an impermissible forfeiture of benefits under

    SACK, Circuit Judge:
    At its core, this appeal presents what seems to be a simple question of
    contract interpretation, obscured by the argot of federal law governing employee
    retirement income plans. On one hand, the plaintiffs-appellees—a class of
    former employees of Colgate-Palmolive Co. ("Colgate")—assert that certain
    provisions of Colgate's retirement plan have a single, unambiguous meaning that
    entitles them to greater benefits. On the other, the defendants-appellants—
    Colgate and some of its affiliated entities and officers—argue that those
    provisions are ambiguous, and that we must therefore defer to their preferred
    interpretation, which would result in lesser cumulative benefit payments to the
    plaintiff class.

    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    After extensive litigation in which summary judgment was granted to the
    defendants on several counts, 1 the United States District Court for the Southern
    District of New York (Schofield, J.) granted summary judgment to the plaintiff
    class on a subset of its claims. In particular, the district court entered summary
    judgment for the plaintiffs on Count II, Errors 1 and 3, reasoning that Colgate
    had denied benefits based on two discrete errors in administering a 2005
    amendment to the plan that provided for residual annuity benefits to certain
    plan participants. Colgate now appeals that order and final judgment of the
    district court. We conclude that the plaintiffs-appellees' interpretation of
    Colgate's retirement plan is the unambiguously correct reading of the plan's text,
    and therefore AFFIRM the district court's order and final judgment granting
    summary judgment to the plaintiffs-appellees on Count II, Errors 1 and 3.
    BACKGROUND
    A.      Factual Background
    Defendant-appellant Colgate is a global consumer products company that
    sponsored the Colgate-Palmolive Co.'s Employees' Retirement Income Plan (the
    1The initial grant of summary judgment with respect to those claims is not
    before us on appeal.

    McCutcheon v. Colgate-Palmolive Co.
    "Plan"), an employee pension benefit plan.
    1. The Plan's conversion to a cash balance plan
    The issues in this appeal stem from the Plan's conversion from a final-
    average-pay plan to a cash-balance plan in 1989. 2 Prior to 1989, the Plan
    operated as a final-average-pay plan, meaning that a member's "accrued benefit"
    was calculated based on her final average earnings, along with her years of
    service and estimated Social Security benefits. Under this earlier iteration of the
    Plan, each member (also referred to as a participant) could receive a retirement
    benefit only in the form of a monthly annuity beginning at the normal retirement
    age of 65 (hereinafter referred to as the "grandfathered" annuity, for reasons that
    should soon become clear).
    In 1989, Colgate converted the Plan to a cash-balance plan which provided
    participants with an accrued benefit expressed as a hypothetical cash balance in a
    Personal Retirement Account, or PRA (the "PRA benefit"). Over time, Colgate
    credited each member's PRA with a fixed percentage of her annual pay plus
    2To be precise, the Plan was amended in 1994, with retroactive effect as of July 1,
    1989. This amendment is therefore applicable to all class members paid between
    July 1, 1989, and the effective date of the new 2003 Plan. For the purpose of
    simplifying the complex timeline of relevant events, we refer to the Plan’s
    conversion to a cash-balance model as occurring in 1989.
    4
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    interest. Unlike the pre-1989 version of the Plan (in which members could
    receive grandfathered benefits only as an annuity), the cash-balance plan offered
    participants a choice to receive their PRA benefit as either a lump sum or a
    lifetime monthly annuity.
    After the Plan shifted from final-average-pay to cash-balance, Colgate
    needed to account for those participants who had already accrued benefits under
    the pre-1989 plan but remained employed after the conversion. To do so,
    Colgate grandfathered participants who had already accrued benefits under the
    prior final-average-pay plan and offered them the option to purchase the
    continuing accrual of grandfathered benefits while also accruing PRA benefits
    under the new Plan formula. These participants' rights are contained in Plan
    Appendices A, B, C, and D. See App'x 464–87.3 As relevant here, those
    grandfathered participants could elect to receive their ultimate benefit as either a
    lump sum payment or an annuity. According to Appendix C § 2(b), if a
    grandfathered participant chose to receive an annuity, she was "eligible" to
    3Generally, Appendix A defines various terms used in calculating grandfathered
    benefits, Appendix B specifies how to calculate grandfathered benefits, and
    Appendices C and D describe the benefits available to certain participants who
    remained employed after the Plan's 1989 conversion.
    5

    McCutcheon v. Colgate-Palmolive Co.
    receive the "larger of" the two different annuities that were accruing: (i) her
    grandfathered annuity, or (ii) her PRA annuity adjusted to include her
    contributions toward maintaining the grandfathered annuity. 4 Id. at 480–81. If,
    on the other hand, a grandfathered participant chose to receive a lump sum,
    Appendix C § 2(a) provides that the lump sum would reflect the value of her
    accrued PRA benefit plus the value of any contributions she made to continue
    her prior grandfathered benefits. See id. at 480. 5
    2. Colgate's calculation of benefits leads to two distinct forfeitures
    To resolve the issues raised on appeal, we must first review some of the
    legal requirements that govern the Plan and how Colgate's failure to comply
    with those requirements led to two distinct forfeitures of benefits.
    The parties agree that at all relevant times the Plan was a "defined benefit
    plan" under the Employee Retirement Income Security Act of 1975 ("ERISA"), 29
    4We refer to the larger of these two annuities hereinafter as a participant's
    "winning" annuity.
    5Because of the way in which Appendix C is drafted, there are multiple
    provisions that could be identified as "Appendix C § 2(a)" or "Appendix C
    § 2(b)." In this opinion, we use those terms to refer to the corresponding
    provisions found in the record at App'x 480–81, which "shall be applicable" "[i]f a
    Member elects to make Contributions to Maintain Prior Plan Benefits starting
    July 1, 1989 and continues to do so until h[er] separation from service." App'x
    480.
    6
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    U.S.C. § 1001 et seq., because the plan guarantees a defined level of benefits,
    known as accrued benefits. For defined benefit plans, ERISA defines the term
    "accrued benefit" to mean "the individual's accrued benefit determined under the
    plan and . . . expressed in the form of an annual benefit commencing at normal
    retirement age." ERISA § 3(23)(A), 
    29 U.S.C. § 1002
    (23)(A). In other words, "the
    accrued benefit under a defined benefit plan must be valued in terms of the
    annuity that it will yield at normal retirement age," which here is 65. Esden v.
    Bank of Bos., 
    229 F.3d 154
    , 163 (2d Cir. 2000). 6
    The value of the age-65 annuity to which a participant is entitled under the
    Plan terms serves as the baseline against which a participant's actual benefits are
    measured. That said, ERISA does not restrict an employer to providing a benefit
    only in the form of an annuity; it can also offer an employee the option to receive
    benefits in a lump sum instead. But the "present value" requirements of § 417(e)
    of the Internal Revenue Code ("I.R.C.") and § 205(g) of ERISA require that, under
    6Federal law defines an "accrued benefit" as an "annual benefit," i.e., an annuity.
    ERISA § 3(23)(A), 
    29 U.S.C. § 1002
    (23)(A). Somewhat oxymoronically, the Plan
    offers a "monthly annuity." See, e.g., App'x 405, 434–35. For the sake of
    simplicity, because the Plan's monthly benefit is effectively a traditional annuity
    paid out in more frequent installments, we treat the "monthly annuity" to which
    a member is entitled under the Plan as the legally defined "accrued benefit"
    against which any optional form of the benefit should be compared.
    7
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    a defined benefit plan, any lump sum distribution be the actuarial equivalent of a
    member's normal retirement benefit. See I.R.C. § 417(e); ERISA § 205(g), 
    29 U.S.C. § 1055
    (g); see also Esden, 
    229 F.3d at
    163–64. In other words, any lump
    sum's value must be equal to the value of the age 65 single life annuity to which
    the member is otherwise entitled, accounting for, among other things, the time
    value of money and the life expectancy of the recipient. This actuarial-
    equivalence requirement is designed to protect employees from employers who
    might entice them "to sell their pension entitlement back to the company cheap"
    by offering a lump sum option that is less valuable than the delayed annuity they
    would receive upon reaching retirement age. Berger v. Xerox Corp. Ret. Income
    Guarantee Plan, 
    338 F.3d 755
    , 762 (7th Cir. 2003).
    The first forfeiture caused by Colgate's implementation of the Plan
    involves a so-called "whipsaw violation," which relates to the inequivalence of
    the two optional forms of the PRA benefit: the PRA lump sum and the PRA
    annuity. To ensure that a lump sum is actuarially equivalent to the retirement-
    age annuity guaranteed by a cash-balance plan, the plan administrator (here,
    Colgate) must perform what is known as a whipsaw calculation. See Laurent v.
    Pricewaterhouse Coopers LLP, 
    794 F.3d 272
    , 275 (2d Cir. 2015) (explaining that a
    8
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    whipsaw calculation is used to determine the "difference between the
    hypothetical value of a cash balance plan account at any given time and the value
    of the account as an annuity payable at normal retirement age"). Generally
    speaking, to perform the whipsaw calculation, a plan administrator typically
    projects a participant's hypothetical cash balance forward to normal retirement
    age using a certain interest rate (the "projection rate") and then discounts that
    amount back to present value with a certain interest rate (the "discount rate").
    Projection rates may be set by a plan, but the discount rate is statutorily capped.
    See Esden, 
    229 F.3d at 159
    . In the context of the Plan, to properly compute a
    participant's lump sum benefit, Colgate had to increase the participant's
    hypothetical cash balance to age 65 using the plan-prescribed "projection rate,"
    convert that amount into the age 65 annuity (i.e., the PRA annuity), convert that
    age 65 annuity to a lump sum, and finally discount the lump sum back to present
    value using the statutorily-prescribed "discount rate." 7
    7 Colgate amended the Plan in 2003 so that the projection rate used to convert a
    member's cash balance to age 65 was the same as the discount rate prescribed by
    I.R.C. § 417(e). The whipsaw violation was therefore resolved on a prospective
    basis as of the date of this amendment, but it remained an issue retrospectively
    for participants who had been underpaid while the higher projection rate was in
    effect.
    9
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    As relevant to the class members before us, § 1.3 of the Plan selected as a
    projection rate the 20-year Treasury bill interest rate plus 1% (the "20+1% rate").
    See App'x 405–06 (requiring that the 20+1% rate must be used "[f]or purposes of
    converting a Member’s Account into a single life annuity payable for the life of
    the Member starting at Normal Retirement Date"). In the whipsaw calculation,
    that rate was used to project the hypothetical PRA account balance forward to
    the age of 65 and to convert that projected balance into the PRA annuity. The
    discount rate used to bring the age 65 projected lump sum back to present value
    is set by I.R.C. § 417(e). From 1989 to 2002, federal law mandated that the
    discount rate could not be higher than the Pension Benefit Guaranty Corporation
    rate (the "PBGC rate"). See McCutcheon v. Colgate-Palmolive Co. (Colgate II), 
    481 F. Supp. 3d 252
    , 257 (S.D.N.Y. 2020) (citing I.R.C. § 417(e)(3)(C); I.R.S. Notice 87-20,
    1987-
    1 C.B. 456
     (Feb. 9, 1987)).
    For the relevant period, however, Colgate used the 20+1% rate as both the
    projection rate and the discount rate, despite the 20+1% rate being considerably
    higher than the PBGC rate during that time. See App'x 1367. As a result of using
    the same rate to project and discount, a member who elected to receive her
    benefits as a lump sum received a payment that was necessarily equal to her
    10
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    hypothetical PRA account value. Insofar as this undervalued lump sum was not
    actuarially equivalent to a member's accrued benefit, these participants suffered
    a forfeiture.
    The second forfeiture at issue is a "grandfathered benefit forfeiture," which
    relates to the Plan's failure to compare the PRA lump sum to the grandfathered
    annuity for certain members who continued to make contributions to maintain
    their grandfathered benefits. As previously noted, these grandfathered
    participants effectively had two benefits accruing at the same time, and the Plan
    gave them the option to choose to receive either an annuity or a lump sum—the
    values of which were required to be actuarially equivalent. For the purposes of
    present-value requirements under federal law, a grandfathered member's
    "accrued benefit"—i.e., the baseline annuity to which her lump sum payment
    must be actuarially equivalent—was the age 65 single life annuity to which she
    was entitled under the Plan. See I.R.C. § 411(a)(7) (defining "accrued benefit");
    accord ERISA § 3(23)(A). Under Appendix C § 2(b), that "accrued benefit" would
    be her "winning" annuity, i.e., whichever of the PRA annuity or grandfathered
    annuity was more valuable. But because there was no lump-sum form of the
    grandfathered benefit, under Appendix C § 2(a), a participant who elected to
    11
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    receive a lump sum would obtain a payment that (at least in theory) reflected
    only the value of her PRA annuity, even if her winning annuity—and, thus, her
    legally defined accrued benefit—was her grandfathered annuity. 8 As a result,
    some members whose larger grandfathered annuities were their "winning"
    annuities received lump sum payments that (if properly calculated) would only
    be actuarially equivalent to their smaller PRA annuities.
    Thus, a member with a winning grandfathered annuity who elected a
    lump sum payment suffered two nested forfeitures: first, her PRA lump sum was
    not actuarially equivalent to her PRA annuity because of Colgate's whipsaw
    violation, and second, even if the two forms of the PRA benefit had been
    actuarially equivalent, her properly calculated PRA lump sum still would have
    been worth less than the present value of her winning grandfathered annuity.
    3. The Residual Annuity Amendment
    In 2005, Colgate amended the Plan through a Residual Annuity
    Amendment (the "RAA"). The RAA applied retroactively "[e]ffective as of July 1,
    1989," and granted a residual annuity benefit to any participant who (i) elected a
    8We say "in theory" because, as noted above, a member's PRA lump sum was not
    the actuarial equivalent of her accrued PRA benefit due to the separate whipsaw
    violation.
    12
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    lump sum payment and (ii) was "entitled to a greater benefit than h[er] Accrued
    Benefit" as defined under the Plan. App'x 366. 9
    The core of the issues on appeal concern Colgate's interpretation and
    implementation of the RAA. In pertinent part, the RAA provides that a
    qualifying member’s residual annuity "shall be computed by subtracting the age
    65 single life annuity Actuarial Equivalent amount of the Member’s lump sum
    payment from the age 65 single life annuity benefit otherwise payable to the
    Member under Appendices B, C, or D, as applicable." App'x 366. Parsing this
    clause, the amount of a qualifying member's residual annuity under the RAA
    equals the difference between two values. The first value is "the age 65 single life
    annuity Actuarial Equivalent amount of the Member's lump sum payment." Id.
    In less technical terms, this figure reflects the value of the lump sum payment
    that the member actually received, converted into an annuity payable at the age
    of 65 for the purpose of comparison. The first value is therefore a hypothetical
    9
    Section 1.2 of the Plan defines "Accrued Benefit" as "a monthly annuity for the
    life of the Member . . . commencing at Normal Retirement Age or any later date,
    which is the Actuarial Equivalent of the Member’s Account[.]" App’x 405. In
    other words, this aspect of the Plan’s definition of "Accrued Benefit" refers to a
    participant’s PRA annuity.
    13
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    annuity that is the actuarial equivalent of the lump sum payment that Colgate
    paid to a member (the "AE of LS").
    The second value (from which the AE of LS is subtracted to calculate the
    residual annuity) is the "age 65 single life annuity benefit otherwise payable to
    the Member under Appendices B, C or D, as applicable." Id. As the precise
    meaning of this clause is critical to this appeal, it is discussed at some length
    below. According to the defendants-appellants, in 2004, Colgate discovered the
    grandfathered benefit forfeiture described above and adopted the RAA to
    address only that forfeiture. See Appellants' Br. 14. Thus, Colgate contends that
    the "age 65 single life annuity benefit otherwise payable to the Member under
    Appendices B, C or D, as applicable," refers only to the grandfathered annuity
    (and not to the PRA annuity, even if it is a member's winning annuity). Id. at 14–
    15 (quoting App'x 366). The plaintiffs-appellees, on the other hand, contend that
    this language unambiguously refers to a member's winning annuity under
    Appendix C § 2(b) and argue that whatever the RAA's purpose, its plain
    language operates to remedy both the grandfathered benefit forfeiture and the
    whipsaw forfeiture for covered participants. See Appellees' Br. 11.
    14
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    Although the RAA was technically effective as of July 1, 1989, Colgate
    initially implemented the RAA only prospectively, granting residual annuities to
    qualifying employees who retired after its adoption in 2005. Thus, at first, there
    was no retroactive application of the RAA to participants who retired between
    July 1989 and February 2005.
    4. The Colgate I settlement and retroactive RAA application
    In 2007, an ERISA class action was initiated against Colgate on behalf of
    thousands of Plan participants who alleged that Colgate had miscalculated their
    pension benefits as a result of the whipsaw violation. See In re Colgate-Palmolive
    Co. ERISA Litig. (Colgate I), 
    36 F. Supp. 3d 344
    , 347 (S.D.N.Y. 2014). The class was
    comprised of former Colgate employees—including both those whose
    employment started before and after the 1989 plan conversion—who had elected
    to receive their PRA benefit as a lump sum, but who received lump sums worth
    less than the actuarial equivalent of the PRA annuity benefit to which they were
    entitled, in violation of § 417(e)'s present-value requirements.
    In May 2010, the parties in Colgate I reached a preliminary agreement to
    settle the plaintiffs' claims. At the time of this preliminary agreement, plaintiffs'
    counsel was unaware of the existence of the RAA. Upon learning of the RAA in
    15
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    July 2011, the plaintiffs continued their efforts to settle Colgate I, which
    eventually culminated in a settlement agreement that excluded from its scope
    "any and all past, present and future" claims "that are based upon, or arise under
    the Residual Annuity Amendment." App'x 304. In July 2014, the United States
    District Court for the Southern District of New York (Schofield, J.) approved this
    $45 million settlement. See Colgate I, No. 07–cv–9515, 
    2014 WL 7929831
     (S.D.N.Y.
    July 8, 2014) (final order and judgment); see also Colgate I, 
    36 F. Supp. 3d at 346
    .
    After disclosure of the RAA during the Colgate I settlement proceedings,
    Colgate began to implement the RAA retroactively, granting millions of dollars
    of additional annuity benefits to several hundred former participants who had
    opted to receive lump sum payments between 1989 and 2005. Based on Colgate's
    reading of the RAA, it calculated those members' residual annuities by
    subtracting the AE of LS from the grandfathered annuity exclusively, even when
    a member's PRA annuity—rather than the grandfathered annuity—was her
    "winning" annuity under the Plan.
    5. McCutcheon's administrative claim and appeal
    Plaintiff-appellee Rebecca McCutcheon was a Colgate employee from 1979
    to 1994. McCutcheon made contributions to continue her eligibility for
    16
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    grandfathered benefits after the Plan's 1989 conversion and elected to receive her
    pension benefit as a lump sum at the time of her resignation. She also received a
    settlement payment as part of the Colgate I litigation.
    On July 30, 2014, McCutcheon filed an administrative claim alleging that
    she was entitled to a residual annuity under the RAA. 10 By letter dated
    November 4, 2014, the Employee Relations Committee of Colgate-Palmolive Co.
    (the "Committee") denied her claim, determining that she was not entitled to any
    additional benefit under the RAA because the age 65 actuarial equivalent of her
    lump sum plus her Colgate I settlement proceeds was greater than her
    grandfathered annuity. On April 6, 2015, McCutcheon appealed the Committee's
    denial, identifying four errors that the Committee allegedly committed when
    calculating her residual annuity. On June 4, 2015, the Committee denied her
    appeal.
    10Colgate calculated McCutcheon's grandfathered annuity as $731.31 per month
    and her PRA annuity as $1,125.38 per month. See App'x 790 ¶ 211. Therefore,
    her winning annuity under Appendix C § 2(b) was her PRA annuity. She elected
    to receive a lump sum of $22,425.64, and she received a Colgate I settlement of
    $11,226.03 before expenses and fees. See App'x 373. Based on the value of her
    lump sum and settlement, Colgate calculated her AE of LS as $752.84. See App'x
    374. Therefore, based on Colgate's calculations, her lump sum payment was
    worth more than her grandfathered annuity, but less than her winning PRA
    annuity.

    McCutcheon v. Colgate-Palmolive Co.
    B.      District Court Proceedings
    After her administrative appeal was denied, McCutcheon filed this action
    in the United States District Court for the Southern District of New York on
    behalf of a putative class against Colgate, the Plan, the Committee, and two
    Colgate Vice Presidents who served on the Committee, Laura Flavin and Daniel
    Marsili. 11 Count I, which is not a class claim and is not before us on appeal,
    alleged that the defendants violated 
    29 C.F.R. § 2560.503-1
     by failing to produce
    all relevant documents and information during McCutcheon's claim and appeal.
    Count II, which is before us, alleged that the class plaintiffs were wrongly denied
    residual annuities under the RAA based on four distinct errors Colgate made
    when interpreting and calculating such benefits. The district court granted the
    motion for class certification as to Count II and appointed McCutcheon as the
    class representative. Caufield v. Colgate-Palmolive Co., No. 16-cv-4170, 
    2017 WL 3206339
    , at *6, *8 (S.D.N.Y. July 27, 2017). As explained by the district court,
    "each Class Member (1) was a Colgate employee in July 1989, (2) received a lump
    sum payment from the Plan and (3) is entitled to a greater benefit under any of
    11The complaint originally asserted five causes of action, but the magistrate
    judge overseeing the pre-trial proceedings bifurcated the case and ordered only
    Counts I and II to proceed.
    18

    McCutcheon v. Colgate-Palmolive Co.
    Appendices B, C or D than his or her Accrued Benefit as defined in Plan § 1.2."
    Colgate II, 481 F. Supp. 3d at 260. The plaintiffs estimate that the class contains
    approximately 1,200 people with claims totaling some $300 million.
    After two years of discovery, Colgate moved for summary judgment. The
    district court granted the motion in part, dismissing (i) Count I; (ii) Count II,
    Error 2; and (iii) Count II, Error 4 as to the Class but not as to McCutcheon
    herself. See McCutcheon v. Colgate-Palmolive Co., No. 16-cv-4170, 
    2020 WL 3893303
    , at *16 (S.D.N.Y. July 10, 2020). 12 The district court denied summary
    judgment to Colgate on Count II, Errors 1 and 3. See 
    id.
     The plaintiffs
    subsequently moved for summary judgment on Count II, Errors 1 and 3, and
    12In Error 2, the plaintiffs argued that Colgate used the wrong Plan provision to
    determine the Estimated Social Security Primary Insurance Amount when
    calculating benefits under the grandfathered formula. See App'x 193. In Error 4,
    the plaintiffs argued that, while the Colgate I settlement agreement required
    future residual annuities to be offset by any settlement proceeds, the Plan itself
    was not amended prior to applying the offsets to the payments, and retroactively
    amending the plan after applying the offsets would result in an impermissible
    cutback in benefits under ERISA and the I.R.C. See App'x 195. The district court
    denied summary judgment on Error 4 as to McCutcheon because it found a more
    generous standard of review applied to her claim specifically than the class's
    Error 4 claim. McCutcheon, 
    2020 WL 3893303
    , at *15–16. McCutcheon
    subsequently waived her right to de novo review of her claim based on this
    Error, which effectively merged her individual claim with the class's claim that
    the district court dismissed. See Colgate II, 481 F. Supp. 3d at 270. Neither of
    these alleged Errors is before us on appeal.
    19
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    sought entry of a final judgment in their favor. On August 24, 2020, the district
    court issued an order granting the plaintiffs' motion for summary judgment.
    Colgate II, 481 F. Supp. 3d at 256.
    In Error 1, the plaintiffs claimed that Colgate miscalculated residual
    annuities, leading to a forfeiture. Id. at 261. The district court determined that
    Colgate's reading of the RAA—that both eligibility and the amount of the
    residual annuity is determined by comparing the lump sum paid with only the
    grandfathered annuity—was erroneous as a matter of law. Id. As to eligibility,
    the district court agreed with the plaintiffs that "if either the Grandfathered
    benefit exceeds the Accrued Benefit as defined in Plan § 1.2 [i.e., the PRA
    annuity] or the participant elected to make Employee Contributions, then the
    participant will be entitled to a Residual Annuity." Id. at 262. The court then
    concluded that "[b]ased on a plain reading of the RAA," "the amount of the
    Residual Annuity is determined by comparing the Age 65 AE of LS . . . with the
    greater of the Grandfathered Benefit or the Member's Accrued Benefit as defined
    in Plan § 1.2 [i.e., the PRA annuity] plus Employee Contributions." Id. (emphasis
    in original).
    In Error 3, the plaintiffs asserted that Colgate violated ERISA when it used
    20
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    a pre-retirement mortality discount ("PRMD") to determine actuarial equivalence
    when calculating residual annuities. See id. at 266–67. Generally speaking, when
    calculating the present value of a retirement benefit, a mortality discount can be
    used to account for the possibility that a participant may die before reaching the
    eligibility age for that benefit. Here, pursuant to the Plan’s terms, Colgate
    incorporated a PRMD when calculating a participant’s AE of LS and age 65
    annuity benefit, thereby diminishing the value of the residual annuities under
    the RAA. The district court granted summary judgment to the plaintiffs on Error
    3 on the ground that the defendants failed to respond to the plaintiffs' arguments
    in their opposition brief. Id. at 267. Nevertheless discussing the merits, the court
    explained that, under the Plan, a member's benefit "must be paid in all events
    and does not decrease if the Participant dies prior to reaching age sixty-five." Id.
    at 268. That is, if a member were to die prior to retirement age, a benefit of
    substantially similar value is nonetheless paid to that member's beneficiary. The
    district court adopted reasoning from cases in our sister circuits that "applying a
    pre-retirement mortality discount to a retirement benefit that does not decrease if
    the participant dies would result in a lump sum that was less than the actuarial
    equivalent of the annuity it [was] supposed to replace," and would "result in a
    21
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    forfeiture prohibited by ERISA." Id. at 267 (alteration in original) (citation
    omitted).
    Finally, the district court ordered Colgate to recalculate all class members'
    RAA annuities using the 20+1% rate as the projection rate to convert a below-
    retirement-age participant's cash balance into an age 65 annuity and the PBGC
    rate as the discount rate to determine the Age 65 AE of LS. Id. at 269.
    The defendants-appellants now appeal the district court's grant of
    summary judgment to the plaintiffs-appellees on Count II, Errors 1 and 3, and
    the district court's determination that Colgate must use the above-mentioned
    rates to recalculate participants' residual annuities.
    DISCUSSION
    I.      Standard of Review
    "We review a district court's decision to grant summary judgment de novo,
    construing the evidence in the light most favorable to the party against which
    summary judgment was granted and drawing all reasonable inferences in its
    favor." Halo v. Yale Health Plan, Dir. of Benefits & Recs. Yale Univ., 
    819 F.3d 42
    , 47
    (2d Cir. 2016) (citation omitted). Summary judgment is appropriate if the record
    establishes that "there is no genuine dispute as to any material fact and the
    22
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    movant is entitled to judgment as a matter of law." Fed. R. Civ. P. 56(a). "A
    genuine issue of material fact exists if 'the evidence is such that a reasonable jury
    could return a verdict for the nonmoving party.'" Nick's Garage, Inc. v. Progressive
    Cas. Ins. Co., 
    875 F.3d 107
    , 113 (2d Cir. 2017) (citation omitted). In ERISA cases
    where a pension plan participant moves for summary judgment against a plan
    administrator, summary judgment is appropriate when the plan language
    "unambiguously" supports the participant's interpretation. See O'Neil v. Ret. Plan
    for Salaried Emps. of RKO Gen., Inc., 
    37 F.3d 55
    , 58–59 (2d Cir. 1994).
    II.     Error 1
    With respect to Error 1, the plaintiffs claimed that Colgate had
    miscalculated class members' residual annuities, resulting in an impermissible
    forfeiture of benefits. Based on its interpretation of the RAA's text, Colgate had
    calculated residual annuities by comparing the AE of LS only with a member's
    grandfathered annuity. The district court granted summary judgment to the
    class, concluding that the unambiguous language of the Plan required Colgate to
    calculate residual annuities by comparing the AE of LS with the greater of (i) the
    grandfathered annuity or (ii) the PRA annuity plus employee contributions made
    to maintain eligibility for grandfathered benefits. See Colgate II, 
    481 F. Supp. 3d 23
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    at 262. Under the district court's interpretation, an eligible member would
    receive a residual annuity if either of those annuities is greater than the value of
    the lump sum they were paid.
    We agree with the district court that the text of the RAA is unambiguous
    and requires Colgate to calculate a member's residual annuity by subtracting the
    AE of LS from that member's winning annuity under Appendix C § 2(b).
    A.              Relevant Plan Provisions
    Central to this appeal is the language of the RAA and the related language
    of Plan Appendix C § 2(b), which the parties agree is the relevant appendix
    provision for purposes of the analysis.
    The RAA states, in relevant part:
    Effective as of July 1, 1989, a Member who, under any of Appendices
    B, C or D, is entitled to a greater benefit than his Accrued Benefit . . . ,
    and who chooses to receive his benefit under this Lump Sum Payment
    Option, which is the Actuarial Equivalent of his Accrued Benefit . . . ,
    shall receive in addition to such lump sum payment an additional
    benefit, commencing at the same time and payable in the standard
    form applicable to such Member . . . . A Member may not elect any
    other form of payment option with respect to this additional benefit.
    Such additional benefit shall be computed by subtracting the age 65
    single life annuity Actuarial Equivalent amount of the Member’s
    lump sum payment [i.e., the AE of LS] from the age 65 single life annuity
    benefit otherwise payable to the Member under Appendices B, C or D,
    as applicable, and applying to such remainder early retirement
    24
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    reductions applicable to the Member’s benefit based on the Member’s
    age at benefit commencement.
    App'x 366 (emphases added).
    Appendix C § 2(b) states, in relevant part:
    If [a member] elects to receive an annuity settlement instead of a
    single lump sum payment, he shall be eligible for an annuity pursuant
    to Section 6.2 . . ., Section 6.3 . . . or Section 6.4(a)(ii) . . . of the Plan that
    provides for him to receive the larger of:
    (i)     the benefit that he would have received had he continued
    under the Plan as in effect prior to July 1, 1989, pursuant to
    Appendix B . . . [i.e., his grandfathered annuity]; or
    (ii)    the benefit payable pursuant to Section 6.2 . . . , Section 6.3 . . .
    or Section 6.4(a)(ii) . . . of the Plan [i.e., his PRA annuity], which
    is the Actuarial Equivalent of the Member's Accrued Benefit . . .
    plus his Contributions to Maintain Prior Plan Benefits with
    interest . . . at his Benefit Commencement Date.
    App'x 480–81 (emphases added).
    B.              Principles for Construction of Plans
    "ERISA plans are construed according to federal common law," Fay v.
    Oxford Health Plan, 
    287 F.3d 96
    , 104 (2d Cir. 2002), and general principles of
    contract law apply to their interpretation, Burke v. PriceWaterHouseCoopers LLP
    Long Term Disability Plan, 
    572 F.3d 76
    , 81 (2d Cir. 2009) (per curiam). The first
    step in interpreting a plan is to determine whether the plan's terms are
    ambiguous. See Strom v. Siegel Fenchel & Peddy P.C. Profit Sharing Plan, 
    497 F.3d 25
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    234, 244 n.6 (2d Cir. 2007); O'Neil, 37 F.3d at 58–59. "Whether ERISA plan
    language 'is ambiguous is a question of law that is resolved by reference to the
    contract alone.'" Strom, 497 F.3d at 244 n.6 (quoting O'Neil, 37 F.3d at 59).
    "Language is ambiguous when it is capable of more than one meaning when
    viewed objectively by a reasonably intelligent person who has examined the
    context of the entire integrated agreement." O'Neil, 37 F.3d at 59 (ellipsis,
    internal quotation marks, and citation omitted).
    If a plan's terms are unambiguous, they must be enforced according to
    those terms without regard for how the plan administrator has otherwise
    interpreted the language "because unambiguous language leaves no room for the
    exercise of discretion." Id. Thus, "[w]here the language is plain and
    unambiguous, a court may construe the [plan] and grant summary judgment."
    Brass v. Am. Film Techs., Inc., 
    987 F.2d 142
    , 148 (2d Cir. 1993). Conversely, if a
    plan's language is ambiguous and the "plan[] invest[s] the administrator with
    broad discretionary authority to determine eligibility," it will be "reviewed under
    the arbitrary and capricious standard." Celardo v. GNY Auto. Dealers Health &
    Welfare Tr., 
    318 F.3d 142
    , 145 (2d Cir. 2003); accord O'Neil, 37 F.3d at 59. When a
    plan's language is ambiguous and "both the [administrator] of [the plan] and a
    26
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    rejected applicant offer rational, though conflicting, interpretations of plan
    provisions, the [administrator's] interpretation must be allowed to control."
    Novella v. Westchester Cnty., 
    661 F.3d 128
    , 140 (2d Cir. 2011) (citation omitted).
    Therefore, whether the language of the plan is ambiguous effectively
    determines the outcome of our analysis. That is, if the RAA unambiguously
    requires the plaintiffs-appellees' interpretation, we must affirm the district
    court's grant of summary judgment. But if the RAA is ambiguous and Colgate's
    preferred reading is reasonable, we would almost surely defer to that reasonable
    interpretation.
    C.              Ambiguity Analysis
    We conclude that the text of the RAA unambiguously requires comparing
    the AE of LS to a participant's Appendix C § 2(b) winning annuity. We are
    unpersuaded by Colgate's attempt to discredit the district court's assertedly
    unambiguous reading as "illogical." See Appellants' Br. 29. We also reject
    Colgate’s proposed alternative interpretation of the RAA, which is not, we think,
    a reasonable reading of the RAA's text, but rather an impermissible effort to
    introduce ambiguity by reference to extrinsic evidence of the RAA's alleged
    27
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    purpose. Accordingly, we affirm the district court's grant of summary judgment
    to the class members on Error 1.
    1. The Plan unambiguously requires residual annuities to be calculated by
    comparing the AE of LS to the Appendix C § 2(b) winning annuity
    The ambiguity dispute in this case focuses primarily on one sentence in the
    RAA, which states that the amount of the residual annuity "shall be computed by
    subtracting the age 65 single life annuity Actuarial Equivalent amount of the
    Member's lump sum payment [i.e., the AE of LS] from the age 65 single life annuity
    benefit otherwise payable to the Member under Appendices B, C or D, as applicable."
    App'x 366 (emphasis added). We begin our analysis of whether this language is
    ambiguous, as we must, "by reference to the contract alone." Strom, 497 F.3d at
    244 n.6 (citation omitted).
    Under the RAA, a residual annuity is computed by calculating the
    difference between (1) the AE of LS—which represents the "amount of the
    Member's lump sum payment" expressed as an annuity for comparison's sake—
    and (2) the "annuity benefit" that is "otherwise payable to the Member under
    Appendices B, C or D, as applicable." App'x 366 (emphases added). Thus, to
    determine that second value, the plan administrator must first find the Appendix
    provision that is "applicable" and then identify which "annuity benefit" is
    28
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    "otherwise payable to the Member under" that Appendix provision.
    In McCutcheon's case, there is no doubt which Appendix provision is
    referenced by the words "as applicable" in the RAA: the first portion of Appendix
    C § 2 states that "[i]f a Member elects to make Contributions to Maintain Prior
    Plan Benefits [i.e., grandfathered benefits] starting July l, 1989 and continues to
    do so until h[er] separation from service"—as McCutcheon did—"the following
    provisions shall be applicable." Id. at 480 (emphasis added). 13
    Having identified the "applicable" appendix provisions, we must then
    determine which "annuity benefit" is "otherwise payable" to the member under
    that portion of Appendix C § 2. The applicable language in Appendix C § 2 is
    structured as a binary between lump sums, in § 2(a), and annuities, in § 2(b). See
    id. at 480–81. Subsection 2(a) states that members "shall be entitled to receive a
    13While these provisions of Appendix C § 2 are applicable here, there are
    numerous other provisions that could be "applicable" depending on a member's
    particular circumstances. To provide a few examples, Appendix B includes
    "Special Rules Applicable to Certain Employees" specified therein, App'x 469;
    Appendix C § 2 includes many other provisions, including some that "shall be
    applicable" to any member who "rescind[s] h[er] decision to make Contributions
    to Maintain [grandfathered benefits]" "[a]t any point before termination of
    employment," see App'x 481–82; Appendix C § 3 includes provisions that "shall
    be applicable" when "a Member elects not to make Contributions to Maintain
    [grandfathered] Benefits," see App'x 482; and Appendix D § 2 includes provisions
    that "shall be applicable" to certain "Older Employees," see App'x 485.
    29
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    single lump sum payment," as McCutcheon chose to do. Id. at 480; see also id. at
    542. Subsection 2(b) identifies which annuity benefit a member like McCutcheon
    would have received had she "elect[ed] to receive an annuity settlement instead
    of a single lump sum payment." Id. at 480. In that circumstance, a member "shall
    be eligible for . . . the larger of" (i) the grandfathered annuity or (ii) the PRA
    annuity plus employee contributions. Id. at 480–81. To summarize, under the
    "applicable" appendix provision, if a lump sum recipient had instead elected to
    receive an annuity, the "annuity benefit" that she "otherwise" would have been
    paid is her Appendix C § 2(b) winning annuity, i.e., the larger of her
    grandfathered annuity or her PRA annuity. 14
    The clear text of the Plan, without more, thus settles the question of
    ambiguity: the RAA is not ambiguous. The text plainly requires a comparison
    between the AE of LS and, in this case, a member's winning annuity under
    Appendix C § 2(b).
    Before engaging with Colgate's preferred alternative reading, first we
    14 Further, for a member like McCutcheon (whose PRA annuity plus employee
    contributions is larger than her grandfathered annuity), the grandfathered
    annuity is decidedly not "otherwise payable" because, per Appendix C § 2(b), she
    is only "eligible for" the "larger" PRA annuity.
    30
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    address Colgate's primary textual counterargument that the interpretation
    outlined above is, in fact, a wholly unreasonable construction of the RAA's text.
    For some members (like McCutcheon), our interpretation of the RAA requires a
    comparison between the values of the PRA lump sum and the PRA annuity.
    Colgate warns that "[a] comparison of the 'new' PRA lump sum and the 'new'
    PRA-based annuity is illogical because . . . the [PRA] Annuity is expressly
    defined in the Plan to be the same benefit the Participant already received as a
    lump sum," and therefore cannot be the "otherwise payable" benefit specified in
    the RAA. Appellants' Br. 29 (emphasis in original). Colgate asserts that "[t]he
    District Court side-stepped the question of whether, as a matter of plan
    interpretation, the 'new' PRA lump sum and the 'new' [PRA] Annuity are the
    same benefit." Id. at 32 (emphasis in original). But, for the reasons explained
    below, Colgate's question is a red herring.
    First, Colgate asserts that once a member has been paid a PRA lump sum,
    the PRA annuity "cannot be the 'otherwise payable' benefit specified in the RAA
    because that benefit was already paid" to the member in a different form. Id. at 29
    (emphases in original). But Colgate omits a significant word from the text of the
    Plan: the RAA does not direct the Plan administrator to identify the "benefit
    31
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    otherwise payable" to a member (as Colgate insists); rather, it refers to the
    "annuity benefit otherwise payable." See App'x 366 (emphases added). Even if the
    PRA lump sum and the PRA annuity are different forms of the same benefit, the
    lump sum is not an "annuity benefit." Therefore, the fact that a lump sum
    version of the PRA benefit had already been paid does not have an impact on
    whether the PRA annuity could be an "otherwise payable" "annuity benefit." 15
    To the contrary, the annuity benefit McCutcheon would otherwise have been
    paid is her PRA annuity had she not elected to receive a lump sum payment.
    Second, Colgate is too quick to dismiss the significance of the RAA's
    invocation of the AE of LS, a computational construct representing the
    hypothetical annuitized value of the lump sum payment actually paid to a
    member for the sake of comparison. See Appellants' Br. 34 (referring to the
    district court's focus on the distinction between the PRA annuity and the AE of
    15To the extent that Colgate argues that the PRA annuity is not otherwise
    payable because a member is not entitled to receive the same benefit twice in
    different forms, this argument would render the RAA a nullity. This argument is
    premised on the unavailability of a PRA annuity once the lump sum option has
    already been elected. But under that premise, neither the PRA annuity nor the
    grandfathered annuity would be "otherwise payable" because a member would
    not be "eligible for [either] annuity" once she elected the lump sum option.
    App'x 480.
    32
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    LS as "an attack on a straw man"). It would be undeniably odd—perhaps even
    "illogical"—if the RAA required comparison of a benefit to itself, such that the
    two values would always be perfectly actuarially equivalent and the resulting
    residual annuity would always equal zero. But that is not what the RAA does.
    As an initial matter—and as emphasized by the district court—from a
    mathematical perspective, the two values are not equivalent because they are
    based on different interest rate assumptions. For reasons discussed in more
    detail infra Section III, we agree that the AE of LS is calculated using the PBGC
    rate, while the PRA annuity is projected using the higher 20+1% rate. See Colgate
    II, 481 F. Supp. 3d at 264–65. Further, the RAA compares the undervalued lump
    sum that a member actually received—represented in the AE of LS—with the full
    annuity benefit to which they were legally entitled. The RAA, which was
    adopted in 2005, was intended to apply retroactively to 1989, thereby covering
    the entire whipsaw violation period. 16 During that period, a member's lump sum
    payment was not actuarially equivalent to her PRA annuity, even though it
    16 The RAA also applied prospectively, but for reasons we address infra Section
    II.C.3, we conclude that the RAA's prospective application—despite the Plan's
    amendment to eliminate the whipsaw issue in 2003—has no bearing on whether
    the RAA can also remedy past whipsaw violations.
    33
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    should have been under federal law. This discrepancy—between the legally
    mandated equivalence of the two forms of the PRA benefit and their real-world
    inequivalence—makes it wholly reasonable for the RAA to compare the
    undervalued lump sum that a member received to the PRA annuity to which she
    would have otherwise been entitled. 17
    Thus, Colgate's "same-benefit" argument does not disturb our conclusion
    that the RAA's language is unambiguous. We find nothing inherently "illogical"
    or ambiguous about the RAA's comparison of the AE of LS to a winning annuity,
    and that comparison does not become any more ambiguous if the lump sum is
    technically an alternate form of the PRA annuity. Because "unambiguous
    language in an ERISA plan must be interpreted and enforced in accordance with
    its plain meaning," Strom, 497 F.3d at 244 n.6 (citation omitted), we affirm the
    district court's grant of summary judgment to the class plaintiffs as to Error 1.
    2. Colgate's preferred reading of the RAA is not a reasonable
    interpretation of the text
    17 Colgate argues that the whipsaw forfeiture was entirely resolved by the Colgate
    I settlement. See Appellants' Br. 40–41; 51–52. We address the relationship
    between the RAA and the Colgate I settlement in detail infra Section II.C.3. For
    now, we simply note that the RAA was drafted prior to the initiation of the
    Colgate I lawsuit, so its settlement has no impact on our analysis of textual
    ambiguity.
    34
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    When Colgate first moved for summary judgment, it unsuccessfully
    argued that the text unambiguously required its preferred reading; now, it
    adopts the position that the RAA is "susceptible to more than one reasonable
    interpretation." Appellants' Br. 27. However, we do not think that Colgate's
    alternative interpretation of the RAA is a reasonable construction of the Plan's
    text.
    Colgate argues that the "annuity benefit otherwise payable to the Member"
    refers only to the grandfathered annuity, not the larger of the grandfathered
    annuity or PRA annuity. According to the defendants-appellants:
    Colgate interprets the term "otherwise payable" in the text of the RAA
    to direct the Committee only to those portions of the Appendices that
    relate to the "old" Grandfathered Formula benefit that would
    otherwise have been payable to Participants had the plan conversion not
    occurred, and not the "new" PRA annuity benefit referenced elsewhere
    in the Appendices (i.e., the "new" 2(b)(ii) Annuity). The reason for this
    is straightforward: the RAA ensures that a Grandfathered Participant
    receives the full value of the "old" benefit that the Participant would
    have received if there were no "new" PRA benefit. The phrase
    "otherwise payable" means the benefit that would otherwise be paid
    if there were no "new" benefit.
    Id. at 28–29 (emphasis added). That is, Colgate argues that it is reasonable to
    interpret the phrase "otherwise payable" as drawing a distinction between pre-
    and post-Plan conversion benefits. The "straightforward" reason Colgate gives
    for its pre-/post-conversion interpretation is that it would fulfill the alleged
    35
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    purpose of the RAA, which Colgate claims is to remedy a forfeiture of
    grandfathered benefits. Colgate also argues that the words "as applicable"—used
    in reference to the Plan's appendices—is similarly ambiguous and could
    reasonably be read to refer to "only those sections of the Appendices that apply
    to the 'old' Grandfathered Formula benefit." Id. at 35. Again, Colgate's only
    support for this interpretation of "as applicable" appears to be that it comports
    with that RAA's alleged purpose "to ensure that the value of the 'old'
    Grandfathered Formula benefit is not forfeited, to the extent it is not fully paid
    by the 'new' PRA lump sum." Id.
    We find nothing in the text of the Plan that suggests that the phrases
    "otherwise payable" and "as applicable" refer specifically to the annuity that
    Colgate would have paid had the Plan not been converted to a cash-balance plan
    in 1989. Indeed, this reading requires inserting into the RAA an additional
    qualification, namely, that "benefit otherwise payable" actually means "benefit
    otherwise payable had the plan conversion not occurred in 1989." Nevertheless,
    Colgate's proffered interpretation begins with the proposition that the RAA is
    simply not concerned with the whipsaw forfeiture, and Colgate urges us to find
    this interpretation reasonable because it would align with that alleged purpose.
    36
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    But Colgate does not divine that purpose from the text of the Plan; instead, it
    draws on "substantial extrinsic evidence demonstrating that the purpose of the
    RAA was to ensure that Grandfathered Participants received the full value of
    their 'old' Grandfathered Formula benefit even if they elected to receive their
    benefit under the 'new' PRA formula as a lump sum." Id. at 39. Colgate thus asks
    us to put the extrinsic evidence cart before the textual horse. The law does not
    permit us to do so.
    We repeat: "It is axiomatic that where the language of a [plan] is
    unambiguous, the parties' intent is determined within the four corners of the
    contract, without reference to external evidence." Feifer v. Prudential Ins. Co. of
    Am., 
    306 F.3d 1202
    , 1210 (2d Cir. 2002). And "[w]hether ERISA plan language 'is
    ambiguous is a question of law that is resolved by reference to the contract alone.'"
    Strom, 497 F.3d at 244 n.6 (emphasis added) (quoting O'Neil, 37 F.3d at 59).
    Therefore, we will not invoke extrinsic evidence of a Plan's purpose to inject
    ambiguity into otherwise unambiguous language. It may be true that Colgate's
    intent when adopting the RAA was different from the actual effect of the text's
    unambiguous language, but that does not control our analysis. See, e.g., AEP
    Energy Servs. Gas Holding Co. v. Bank of Am., N.A., 
    626 F.3d 699
    , 729 (2d Cir. 2010)
    37
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    ("The 'primary concern when interpreting a contract is to ascertain and give
    effect to the intent of the parties as that intent is expressed in the contract.'"
    (citation omitted)).
    3. The language of the RAA is not rendered ambiguous by its effects
    For largely the same reasons, we also conclude that any allegedly unusual
    effects flowing from the RAA's plain meaning do not change our ambiguity
    analysis. That said, we also note that certain effects of our interpretation, which
    may seem odd at first, may not be so confounding upon closer review.
    First, the RAA was adopted in 2005 and was intended to apply both
    retroactively (to 1989) and prospectively. Colgate notes, however, that by 2005
    "the Plan had already been amended to eliminate the whipsaw issue for the 'new'
    PRA benefit on a going-forward basis, meaning that there was no prospective
    § 417(e) issue for the RAA to address." Appellants' Br. 50 (internal citation
    omitted). In our view, the fact that the RAA also applied prospectively does not
    refute the conclusion that, as drafted, it also remedies prior whipsaw violations.
    Rather, the RAA's combined prospective and retrospective application comports
    with an interpretation of the RAA that addresses both of the Plan's forfeiture
    problems—one limited to the past and one continuing—for a large subset of
    members at once.
    38
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    That "two-birds-one-stone" approach to resolving the Plan's overlapping
    forfeiture issues also helps to answer a second question related to the RAA's
    effect. Under the RAA, a residual annuity is available only to a lump sum
    recipient who is "entitled to a greater benefit than h[er] Accrued Benefit," App'x
    366—i.e., any participant whose grandfathered annuity exceeds her PRA annuity
    or who elected to make employee contributions. Yet there are some participants,
    such as those who joined after the Plan's conversion in 1989, who are not eligible
    for a residual annuity but who still suffered a whipsaw forfeiture. Colgate insists
    that "it would have been illogical for [it] to attempt to remedy the [whipsaw]
    forfeiture issue through residual annuities available only to Grandfathered
    Participants, as opposed to remedying the issue for all Plan participants who
    elected to receive their 'new' PRA benefit as a lump sum rather than an annuity."
    Appellants' Br. 50–51 (emphasis in original).
    We think it makes perfectly good sense to conclude that while Colgate was
    in the process of fixing an issue related to forfeiture of grandfathered benefits, it
    would use the same mechanism to partially remedy a contemporaneous
    whipsaw violation, inflicted upon those same grandfathered participants. While
    the Committee was already considering the unique plights of grandfathered
    39
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    participants, it would have been convenient for it to adopt a single amendment
    that remedied all forfeitures that those members had suffered. Thus, we see
    nothing inherently illogical about the RAA's scope, as conceived on our
    construction of its terms.
    Third, Colgate raises concerns about the relationship between the RAA
    and the Colgate I settlement. Colgate asserts that under the plaintiffs-appellees'
    reading the class would receive an unwarranted windfall because members were
    already "compensated for the alleged underpayment of their PRA lump sum in
    Colgate I," and "the current class is claiming again the difference between their
    Colgate I settlement award and their PRA annuity." Reply Br. 17. In Colgate's
    view, when Colgate I was settled, the unlawfulness of the whipsaw violation was
    resolved, even though class members received a settlement award that was less
    than the full gap between the PRA annuity and the lump sum that they had
    received. The reason for the incomplete remedy, Colgate explains, is that the
    settlement award "was discounted to reflect the plaintiffs' likelihood of success
    (as most settlements are)." Id. at 16. That "settled" difference is also the amount
    that the instant class is attempting to recoup via their RAA claims, which Colgate
    40
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    describes as "a second bite at the apple." Id. On our read, the class plaintiffs do
    not stand to earn any undue windfall from a favorable judgment in this case.
    Colgate's complaint is premised on the notion that Colgate I settled all
    claims alleging an impermissible gap between the value of the PRA lump sum
    and the value of the PRA annuity. However, that settlement agreement explicitly
    excluded any claims that were "based upon, or ar[o]se under" the RAA. App'x
    304. Colgate does not dispute that the Colgate I settlement exempted all future
    RAA claims; instead, Colgate again relies on extrinsic evidence of the RAA's
    purpose in an effort to avoid this aspect of the settlement. Colgate begins with
    the assumption that the instant class members' claims could not possibly arise
    under the RAA because "the RAA . . . was never intended to address them."
    Appellants' Br. 52. According to Colgate, "the RAA is about reconciling 'new'
    with 'old'" (i.e., the PRA lump sum with the grandfathered annuity) and "not
    comparing 'new' and 'new'" (i.e., the PRA lump sum and PRA annuity). Id. at 51–
    52 (emphasis in original). But this is a circular argument, essentially claiming
    that Colgate's current interpretation of the RAA must be correct because,
    otherwise, Colgate's interpretation of the RAA (when it settled Colgate I) was
    incorrect.
    41
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    We conclude otherwise. The plaintiffs are not "attempting to relitigate the
    settled claims in Colgate I," id. at 52, by asserting their claims under the
    unambiguous language of the RAA. When Colgate agreed to carve out all future
    RAA claims from the Colgate I settlement, it presumed that its reading of the
    RAA was correct. Now, when faced with a determination that its interpretation
    is erroneous, it seeks to rewrite the settlement. But the settlement clearly
    excludes any claims under the RAA, whatever they may be. App'x 304; see also
    id. at 303 (listing all "Released Claims" and noting "[f]or avoidance of doubt, the
    foregoing does not include any claims arising under the Residual Annuity
    Amendment" (emphasis added)). These plaintiffs, having demonstrated that the
    plain text of the RAA guarantees them an annuity that covers the gap between
    their lump sum and their winning PRA annuity, 18 are now entitled to recover
    that full difference.
    Thus, we decline to read ambiguity into the otherwise unambiguous text
    18The Colgate I settlement clarifies that "any claims under the Residual Annuity
    Amendment are subject to [an] offset" in "an amount based upon the individual
    net settlement benefit" a participant received. App'x 305. This prevents a
    member from collecting more than the full gap between the AE of LS and her
    PRA annuity.
    42
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    of the RAA based on these effects-based arguments. 19
    *   *    *
    We are faced with a choice between (1) the unambiguous meaning of the
    Plan's text that may have some peculiar, though not inexplicable, effects, and (2)
    an interpretation that appears to us to be unreasonable, but that—when viewed
    in light of extrinsic evidence of purpose—results in outcomes that seem more in
    line with the defendants-appellants' preferences. Under these circumstances, as
    we read our case law, we have no choice but to adopt what we see as the
    unambiguous reading. We therefore affirm the district court's grant of summary
    judgment to the plaintiff class on Error 1.
    19These arguments about odd effects of the unambiguous text of the RAA might
    presume that Colgate drafted the Plan clearly and administered it rationally. Of
    course, the history of the Plan is one of flawed design and implementation. From
    not performing whipsaw calculations and failing to achieve equivalence between
    lump sums and grandfathered annuities, to neglecting to retroactively apply
    amendments to correct those original errors, Colgate's cornucopia of missteps
    has led to a patchwork resolution and years of assorted litigation, including this
    case. Given these past events, it is unsurprising that the Commission enacted an
    RAA that only partially resolves the whipsaw forfeiture, or that Colgate would
    reach a legal settlement that does not preclude quite as many future claims as it
    might have hoped. Ultimately, our duty is to interpret the text of the RAA
    faithfully, not to imagine another version that might seem more rational or
    practical.
    43
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    III.    Required Projection Rates
    Colgate argues that irrespective of our decision to affirm the district court's
    grant of summary judgment on Error 1, we should reject the court's conclusion
    that Colgate must use specific rates when calculating the AE of LS and PRA
    annuity for the purpose of determining residual annuities. Colgate insists that,
    instead, the Committee should be entitled to retroactively determine which
    interest rates to use for those calculations. We disagree, and, instead, affirm the
    district court's conclusion that Colgate must use the PBGC rate to calculate the
    AE of LS and the 20+1% rate to calculate the PRA annuity.
    A.      PBGC Rate for AE of LS Calculations
    The district court held that Colgate must use the PBGC rate when
    calculating the AE of LS largely because that was the rate required by I.R.C.
    § 417(e) during the period at issue for present valuing benefits. See Colgate II, 481
    F. Supp. 3d at 264–65, 269. We agree with the district court's conclusion, but for a
    simpler reason: The Plan itself requires the use of the PBGC rate.
    According to minutes of a meeting held on February 6, 2014, the
    Committee met to discuss the calculation of residual annuities. See App'x 854–56.
    Liza LeAndre, the Chief Benefits Counsel, "provided the Committee . . . with an
    44
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    overview of the [RAA]" that aligned with the interpretation Colgate
    unsuccessfully advanced in this litigation. Id. at 855. The minutes then explain:
    Ms. LeAndre indicated that to calculate the residual annuity,
    determining the age 65 Actuarial Equivalent amount of the PRA
    benefit [i.e., the AE of LS] is required. Ms. LeAndre explained that
    the interest rate to be used for this calculation for benefits paid
    between 1989 and 2002 needed to be determined. Ms. LeAndre
    recommended that the applicable interest rate statutory basis of
    PBGC rates be used to calculate residual annuities for such pre-2002
    calculations. The Committee, acting in its settlor capacity, approved
    this recommendation.
    Id. Put simply, the Committee adopted a resolution related to "determining the
    [AE of LS]" for the purpose of "calculat[ing] residual annuities." Id. That
    resolution specified that "the interest rate to be used for this calculation for
    benefits paid between 1989 and 2002" is the PBGC rate. Id. Because these
    documents were adopted by the Committee "in its settlor capacity," id., the terms
    of the resolution are part of the Plan itself. See Hughes Aircraft Co. v. Jacobson, 
    525 U.S. 432
    , 444 (1999) (noting that a "settlor" has the power to amend a Plan and to
    determine "who is entitled to receive Plan benefits and in what amounts, or how
    such benefits are calculated").
    Colgate does not dispute that this resolution is a binding part of the Plan.
    Rather, it emphasizes that LeAndre's pre-resolution summary of the RAA
    maintained (incorrectly) that "the [RAA] provided for residual annuities to be
    45
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    paid to eligible employees who elected a lump sum equal to the excess value of
    the grandfathered formula benefit over the personal retirement (PRA) benefit."
    App'x 855 (emphasis added). Colgate then argues that the selection of the PBGC
    rate was limited to "this calculation of [sic] benefits." Reply Br. 26–27 (emphasis
    omitted). 20
    We disagree. The "calculation" to which the resolution applies is set forth
    in the immediately preceding sentence of the minutes, which instructs that "to
    calculate the residual annuity, determining the [AE of LS] is required." App'x
    855. And the selection of the PBGC rate was made "for this calculation for
    benefits paid between 1989 and 2002." 
    Id.
     The plaintiffs' benefits were paid
    during this time, and the resolution clearly establishes that the PBGC rate shall
    be used to "determin[e] the [AE of LS]" in order "to calculate residual annuities"
    for such members. It matters not that Colgate maintained a more limited,
    atextual interpretation of the RAA at the time of the resolution. The Committee
    adopted an unqualified resolution that "the applicable interest rate statutory
    20 Colgate's reply brief incorrectly quotes the Committee minutes. The minutes
    did not say "the interest rate to be used for this calculation of benefits paid between
    1989 and 2002 needed to be determined," Reply Br. 26 (emphasis added); rather,
    it stated that "the interest rate to be used for this calculation for benefits paid
    between 1989 and 2002 needed to be determined," App'x 855 (emphasis added).
    46
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    basis of PBGC rates be used to calculate residual annuities for such pre-2002
    calculations." 
    Id.
    More broadly, we think it would be arbitrary to construe the text of the
    Plan to allow for distinct calculations of the AE of LS depending on the annuity
    to which it is compared. A comparison of the AE of LS to the PRA annuity is not
    a "new calculation." See Reply Br. 27. It is part of a longstanding calculation that,
    in the past, Colgate incorrectly interpreted. The RAA has always called for only
    a single calculation using two variables: (1) the AE of LS and (2) a member's
    winning annuity under Appendix C § 2(b). It would be unreasonable for Colgate
    to calculate the first variable—the AE of LS—differently depending on a
    characteristic of the distinct second variable in the RAA's formula. Having
    already resolved to calculate the AE of LS for some participants with the PBGC
    rates (and having consistently used that rate in such calculations thus far, see
    Appellants' Br. 56 n.10), we would decline to let Colgate change those rates for
    other participants simply because their winning annuity is different.
    Because we conclude that the Plan itself requires the use of the PBGC rate
    when calculating the AE of LS, we need not address the district court's
    alternative reasons for reaching the same determination.
    47
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    B.      20+1% Rate for Appendix C § 2(b) PRA Annuity Calculations
    We also agree with the district court that for the purpose of calculating the
    Appendix C § 2(b)(ii) PRA annuity, Colgate must use the 20+1% rate to project a
    participant's cash balance account forward and convert it into an age 65 annuity.
    Colgate II, 481 F. Supp. 3d at 264, 269. Section 1.3 of the Plan states that the 20+1%
    rate must be used "[f]or purposes of converting a Member's Account into a single
    life annuity payable for the life of the Member starting at Normal Retirement
    Date." App'x 405–06. A brief recitation of the relevant plan mechanics reveals
    that this is the appropriate rate for calculating a participant's PRA annuity.
    As explained supra Section II.C.1, the RAA requires determining a
    member's winning annuity under Appendix C § 2(b), which is the greater of the
    grandfathered annuity (described in Appendix C § 2(b)(i)) and the PRA annuity
    (described in Appendix C § 2(b)(ii)). See App'x 366, 480–81. Where a member's
    winning annuity is the PRA annuity, it is that member's "Accrued Benefit," 21
    which the Plan defines as "a monthly annuity for the life of the Member . . .
    21This is so because Appendix C § 2(b)(ii) defines the PRA annuity through
    cross-references to the "benefit payable pursuant to Section 6.2 . . . , Section
    6.3 . . . or Section 6.4(a)(ii)," App'x 481, each of which describes "the benefit
    payable to such Member" as "h[er] Accrued Benefit" or some optional form of
    benefit that is the actuarial equivalent thereof, App'x 433–34.
    48
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    commencing at Normal Retirement Age." See id. at 405. This definition matches
    the specifications of § 1.3, which applies "[f]or purposes of converting a
    Member's Account into a single life annuity payable for the life of the Member
    starting at Normal Retirement Date." App'x 405–06. As such, when calculating a
    member's PRA annuity, § 1.3 of the Plan requires Colgate to use the 20+1%
    projection rate.
    Colgate takes issue with this reading, asserting that § 1.3 prescribes the
    20+1% rate only for the "calculation done at age 65 for a Participant who elects
    the annuity form of the [PRA] benefit." Appellants' Br. 56–57. Colgate insists
    that "Section 1.3 says nothing about how to project a cash balance account to age
    65 when a participant chooses to receive his or her benefit prior to normal
    retirement age." Id. at 57 (emphasis in original). That is, Colgate breaks the
    conversion of a member's PRA account into two steps, each permitting different
    interest rates: (1) projection of the account to age 65 and (2) conversion of the age
    65 projected account into an annuity. Colgate argues that § 1.3 only requires
    using the 20+1% rate in step 2 to convert an age 65 PRA account into an annuity,
    but not in step 1 to project the account of a younger member forward to the age
    of 65 prior to conversion. Therefore, Colgate argues that it should be able to
    49
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    decide anew which rate to use when projecting PRA accounts to age 65 for
    residual annuity determinations.
    We are not convinced. First, under the plain text of the Plan, § 1.3's rate
    selection applies to the whole process of "converting" a member's account into an
    age 65 annuity, without distinguishing between the steps of that conversion
    calculation. The Plan selects the 20+1% rate "[f]or purposes of converting a
    Member's Account" without reference to the age of that account. App'x 405. If a
    member is not yet 65, the process of "converting [that] Member's Account" into
    an age 65 single life annuity requires projection. Therefore, for a pre-retirement-
    age member, § 1.3 contemplates that the 20+1% rate will be used to project her
    PRA account to the age of 65 and to convert that projected PRA balance into an
    annuity.
    Second, even if we were to determine that § 1.3 is ambiguous, we would
    not defer to Colgate's interpretation because it would render the plan unlawful.
    "[C]ontracts should not be interpreted to render them illegal and unenforceable
    where the wording lends itself to a logically acceptable construction that renders
    them legal and enforceable . . . ." Walsh v. Schlecht, 
    429 U.S. 401
    , 408 (1977).
    Colgate notes that the Plan "says nothing about how to project a cash balance
    50
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    account to age 65" and that "the applicable interest rate for projection remains an
    open question" that Colgate should have the discretion to resolve. Appellants'
    Br. 57; see also App'x 1560 ("Neither Section 1.3 nor any other section of the Plan
    explains how to project a cash balance account forward to age 65 when a
    participant has not reached normal retirement." (emphasis in original)). But if we
    were to adopt this interpretation, we would, in effect, be concluding that the Plan
    contains no instructions for calculating the accrued benefit for anyone under the
    age of 65. This omission would render the Plan unlawful because I.R.C.
    § 401(a)(25) requires that a participant's accrued benefit be "definitely
    determinable," i.e., calculated under a formula with no employer discretion. See
    I.R.C. § 401(a)(25) ("A defined benefit plan shall not be treated as providing
    definitely determinable benefits unless, whenever the amount of any benefit is to
    be determined on the basis of actuarial assumptions, such assumptions are
    specified in the plan in a way which precludes employer discretion."); 
    Treas. Reg. § 1.401-1

    Third, and finally, we find it difficult to credit Colgate's proposed
    approach because the company's past practice undercuts its interpretation of the
    Plan. In this litigation, Colgate argues that the Plan does not set a projection rate,
    but in practice Colgate consistently used the 20+1% rate as a projection rate to
    calculate the PRA annuity for members who departed during the relevant
    period. Consistent with the text of the Plan, Colgate informed these members
    that their PRA annuities were worth a certain amount based on a 20+1%
    projection rate when they left the company. Colgate cannot arbitrarily adopt a
    lower projection rate to retroactively change those prior valuations.
    bring any claim based on that requirement but merely urge us to consider it
    when evaluating Colgate's own interpretation.
    Colgate additionally argues that it would be reasonable for it to select the lower
    "interest crediting rate" as an alternative. See Appellants' Br. 57; Reply Br. 29. In
    offering this rate, Colgate appears to make conflicting arguments: on one hand it
    claims that the Plan does not offer any explanation for how to project an account
    forward, while on the other, it suggests a reasonable interpretation of the text
    would lead to applying the Plan's interest crediting rate. We see nothing in the
    text that would suggest the Plan selected the interest crediting rate as a
    projection rate when converting accounts into age 65 annuities. The interest
    crediting rate is defined as the rate at which a member's PRA account actually
    accrues interest, without any reference to projecting hypothetical, future account
    growth. See App'x 423. Although the Plan cannot select a projection rate that is
    "less than the interest credits provided under the plan," Esden, 
    229 F.3d at 166
    , it
    does not follow that the Plan could neglect to select a projection rate and simply
    afford the plan administrator the discretion to either select a higher rate or
    default to the interest crediting rate.

    McCutcheon v. Colgate-Palmolive Co.
    For these reasons, we affirm the district court's conclusion that Colgate is
    required to use of the 20+1% projection rate when calculating the Appendix C
    § 2(b)(ii) PRA annuity for the purpose of determining a member's residual
    annuity.
    IV.     Error 3
    A mortality discount accounts for the possibility that the participant might
    die before reaching retirement age when calculating the present value of a
    benefit. The Plan clearly calls for the application of a PRMD, but the plaintiffs
    argued to the district court that Colgate's use of a PRMD to calculate residual
    annuities violated I.R.C. § 417(e)'s and ERISA § 203(a)(2)'s actuarial equivalence
    rules. The district court granted summary judgment to the class plaintiffs on this
    error. See Colgate II, 481 F. Supp. 3d at 266–69. We affirm.23
    In theory, under a plan with no survivorship—i.e., a plan in which a
    member's right to collect her accrued benefit does not pass to her surviving
    beneficiary in the event of her premature death—the promise of an age 65
    23The district court noted that, "[a]s a threshold matter, Defendants d[id] not
    oppose Plaintiffs’ arguments regarding Error 3 in their opposition brief," and
    thus concluded that "[s]ummary judgment [was] granted on this ground alone."
    Colgate II, 481 F. Supp. 3d at 267. On appeal, Colgate makes no effort to contest
    the district court's determination regarding its failure to respond.
    53
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    annuity may be less valuable to a pre-retirement-age member than an upfront
    lump sum payment: the member is guaranteed to get paid now if she elects a
    lump sum, but if she waits for an annuity, she may forfeit her accrued benefit if
    she dies before the age of 65. Colgate claims that its use of a PRMD in calculating
    the AE of LS accurately reflects this risk of early death. However, if a member's
    pre-retirement death would have little or no effect on the value of the benefit that
    she or her beneficiary receives, there is no risk that she will forfeit her benefit.
    Therefore, if a plan guarantees survivor benefits that are substantially similar in
    value to a member's accrued benefit, it is improper to use a PRMD to discount
    the present value of a future annuity.
    This issue appears to be a matter of first impression in this Circuit, but we
    are persuaded—as the district court was—by the careful reasoning of our sister
    circuits finding ERISA and I.R.C. violations in similar circumstances. 24
    For example, in West v. AK Steel Corp., 
    484 F.3d 395
     (6th Cir. 2007), the
    Sixth Circuit held that an impermissible forfeiture occurred when a plan

    administrator applied a PRMD to reduce the present value of a lump sum
    distribution when the death benefit was equal to a participant's accrued benefit,
    
    id. at 411
    . Under the plan in West, "[i]f a Plan participant die[d] before reaching
    the age of 65, the Plan's terms provide[d] that the surviving spouse or other
    beneficiary receive[d] a death benefit 'equal to the participant's pension benefit.'"
    
    Id.
     The death benefit was defined as "the actuarial equivalent of the participant's
    accrued benefit." 
    Id.
     On those facts, the court determined that "[b]ecause the
    beneficiary receives a death benefit equal to the participant's accrued benefit, he
    or she 'steps into [the participant's] shoes and is entitled to his entire pension
    benefit.'" 
    Id.
     (second alteration in original) (quoting Berger, 
    338 F.3d at 764
    ).
    "Even if the participant were to die before the age of 65, his or her beneficiary is
    still entitled to the entire accrued benefit," and the "[u]se of a mortality discount
    for the period before age 65 would, accordingly, result in a partial forfeiture of
    benefits in violation of the ERISA vesting rules (i.e., the anti-forfeiture rules)." 
    Id.
    (citation omitted).
    We find this logic persuasive here, inasmuch as the Plan also defines the
    death benefit as "the Actuarial Equivalent of the Accrued Benefit." App'x 429.
    As a result, in the event of a member's death, her beneficiary would receive a
    55
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    benefit that is effectively equal to the accrued benefit such that the beneficiary
    "steps into the participant's shoes and is entitled to [her] entire pension benefit."
    West, 
    484 F.3d at 411
     (internal alteration and citation omitted). The RAA
    functions to remedy the underpayment of lump sums with an additional residual
    annuity such that the lump sum and residual annuity together ensure
    compliance with the I.R.C.'s and ERISA's present value requirements. See ERISA
    § 203(a)(2); I.R.C. § 417(e); see also 
    26 C.F.R. § 1.417
    (e)-1(d)(1)(i) ("The present
    value of any optional form of benefit cannot be less than the present value of the
    normal retirement benefit . . . ."). Because the value of the benefit paid if a
    member dies before 65 is the same as the Plan's normal retirement benefit, we
    conclude that Colgate's use of a PRMD to determine the present value of the
    lump sum when calculating a make-whole residual annuity results in an optional
    form of benefit that is less than the corresponding normal retirement benefit.
    Colgate's primary response is to argue that the Plan's "death benefit . . . is
    an incidental benefit and not the accrued retirement benefit," so that when a
    participant dies, she forfeits her entire accrued benefit and her beneficiary
    becomes entitled to a distinct benefit of essentially equal value. Appellants' Br.
    59 (emphasis in original). But as reflected in this case law, a Plan administrator
    56
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    cannot undervalue a member's accrued benefit simply because a death benefit is
    defined as the "actuarial equivalent of the accrued benefit" rather than being the
    "accrued benefit" itself. To hold otherwise would defeat the purpose of ERISA's
    and the I.R.C.'s present value requirements.
    Additionally, Colgate relies on a proposed 2016 IRS regulation which it
    claims explicitly rejects our approach regarding the unlawful use of a PRMD in
    this context. See Update to Minimum Present Value Requirements for Defined
    Benefit Plan Distributions, 
    81 Fed. Reg. 85,190
     (proposed Nov. 25, 2016).
    Regardless of whether the document was intended to reflect the IRS's view of
    "current law" as Colgate suggests, see Appellants' Br. 60, the proposed regulation
    has no legal effect. See LeCroy Rsch. Sys. Corp. v. Comm'r of Internal Revenue, 
    751 F.2d 123
    , 127 (2d Cir. 1984) ("Proposed regulations are suggestions made for
    comment; they modify nothing."). Nor is it clear that the proposed regulation—if
    adopted—would support Colgate's argument. 25 In any event, an unadopted IRS
    regulation does not disturb our reasoning.
    25As the district court noted, "the proposed regulation appears to forbid the
    application of a PRMD to determine the present value of the entire accrued
    benefit if any portion of the accrued benefit is derived from contributions made
    by the employee, as is the case here." Colgate II, 481 F. Supp. 3d at 269.
    57
    20-3225
    McCutcheon v. Colgate-Palmolive Co.
    We therefore affirm the grant of summary judgment to the plaintiffs on
    Error 3.
    CONCLUSION
    We have considered the defendants-appellants' remaining arguments on
    appeal and conclude that they are without merit. For the foregoing reasons, we
    AFFIRM the order and final judgment of the district court.
