    2            CHARLESTON AREA MEDICAL CTR. v. UNITED STATES
    Before LOURIE, O’MALLEY, and CHEN, Circuit Judges.
    O’MALLEY, Circuit Judge.
    This case is about the interpretation of 26 U.S.C.
    § 6621(a)(1), which provides the interest rate that the In-
    ternal Revenue Service (“IRS”) must use in calculating the
    amount of interest owed on a tax refund. Section 6621(a)(1)
    requires the IRS to apply a lower interest rate for refunds
    owed to “corporations” than for refunds owed to other types
    of entities. Charleston Area Medical Center, Inc. and
    CAMC Health Education and Research Institute (collec-
    tively, “the Taxpayers”) applied for a tax refund arguing
    that they are entitled to the higher interest rate because
    they are nonprofit entities and not corporations. The IRS
    disagreed and applied the lower interest rate to calculate
    the refund owed to the Taxpayers. The U.S. Court of Fed-
    eral Claims (“Claims Court”) affirmed, reasoning that the
    Taxpayers, who are incorporated under state law, are cor-
    porations under § 6621(a)(1) notwithstanding their status
    as nonprofit entities. Charleston Area Med. Ctr., Inc. v.
    United States, 
    138 Fed. Cl. 626
    (2018). The Taxpayers ap-
    peal.
    Although this is an issue of first impression for our
    court, four other circuits have concluded that a nonprofit
    entity that is incorporated under state law is a corporation
    under § 6621(a)(1). Maimonides Med. Ctr. v. United States,
    
    809 F.3d 85
    (2d Cir. 2015) (“Second Circuit”); United States
    v. Detroit Med. Ctr., 
    833 F.3d 671
    (6th Cir. 2016) (“Sixth
    Circuit”); Med. College of Wis. Affiliated Hosps. v. United
    States, 
    854 F.3d 930
    (7th Cir. 2017) (“Seventh Circuit”);
    Wichita Ctr. for Graduate Med. Educ., Inc. v. United States,
    
    917 F.3d 1221
    (10th Cir. 2019) (“Tenth Circuit”). While it
    is not unheard of for appellants revisiting questions previ-
    ously considered by other courts to hit the circuit split jack-
    pot, this is not such an instance. We agree with the
    interpretative path taken by our sister circuits—not
    CHARLESTON AREA MEDICAL CTR. v. UNITED STATES               3
    because those decisions came first, but because they were
    correct. Therefore, we affirm.
    I. LEGAL BACKGROUND
    The central issue in this appeal is straightforward—
    does the word “corporation,” as it appears in 26 U.S.C.
    § 6621(a)(1), include nonprofit entities that are incorpo-
    rated under state law. But the simplicity ends there. As is
    often the case with issues involving the Internal Revenue
    Code (“Code”), the parties’ arguments rely on various au-
    thorities—including three provisions of the Code, two iter-
    ations of a Treasury regulation, and a notice of proposed
    rulemaking issued by the IRS on March 1, 2018. We detail
    each below.
    A. Code Provisions
    Section 6621(a)(1), the specific provision at issue in this
    appeal, recites:
    (1) OVERPAYMENT RATE The overpayment rate es-
    tablished under this section shall be the sum of—
    (A) the Federal short-term rate determined under
    subsection (b), plus
    (B) 3 percentage points (2 percentage points in the
    case of a corporation).
    To the extent that an overpayment of tax by a cor-
    poration for any taxable period (as defined in sub-
    section    (c)(3),   applied    by     substituting
    “overpayment” for “underpayment”) exceeds
    $10,000, subparagraph (B) shall be applied by sub-
    stituting “0.5 percentage point” for “2 percentage
    points”.
    
    Id. (emphases added).
    Section 6621(a)(1) provides that if
    the taxpayer is a corporation and its overpayment exceeds
    $10,000, the first $10,000 will bear interest at the Federal
    short-term rate plus two percentage points, and the
    4           CHARLESTON AREA MEDICAL CTR. v. UNITED STATES
    remainder will bear interest at the Federal short-term rate
    plus one-half of a percentage point. If the taxpayer is not
    a corporation and its overpayment exceeds $10,000, the en-
    tire overpayment will bear interest at the Federal short-
    term rate plus three percentage points. 
    Id. In plain
    Eng-
    lish, a taxpayer’s refund is greater if the IRS applies the
    formula set out for noncorporations than if it applies the
    formula set out for corporations.
    The sentence in § 6621(a)(1) beginning with the phrase
    “To the extent” is referred to as the “flush language.” The
    flush language cross-references subsection (c)(3), which in
    turn, provides:
    (3) LARGE CORPORATE UNDERPAYMENT For pur-
    poses of this subsection—
    (A) IN GENERAL The term “large corporate under-
    payment” means any underpayment of a tax by a C
    corporation for any taxable period if the amount of
    such underpayment for such period exceeds
    $100,000.
    (B) TAXABLE PERIOD For purposes of subparagraph
    (A), the term “taxable period” means—
    (i) in the case of any tax imposed by subtitle A, the
    taxable year, or
    (ii) in the case of any other tax, the period to which
    the underpayment relates.
    
    Id. (emphases added).
         While § 6621 does not define “corporation” for purposes
    of that section, § 7701(a)(3) provides a Code-wide definition
    for the term:
    (a) When used in this title, where not otherwise
    distinctly expressed or manifestly incompatible
    with the intent thereof—
    ***
    CHARLESTON AREA MEDICAL CTR. v. UNITED STATES                 5
    (3) CORPORATION The term ‘corporation’ includes
    associations, joint-stock companies, and insurance
    companies.
    
    Id. (emphasis added).
                      B. Treasury Regulations
    Treasury has promulgated different versions of regula-
    tions that attempt to classify various entities as corpora-
    tions. The Kintner Regulations were enacted in 1960 and
    remained in effect through 1996, when they were super-
    seded by the modern regulations on January 1, 1997. 25
    Fed. Reg. 10,928 (Nov. 17, 1960); 61 Fed. Reg. 66,584 (Dec.
    18, 1996). While in effect, the Kintner Regulations “aid[ed]
    in classifying business associations that were not incorpo-
    rated under state incorporation statutes but that had cer-
    tain characteristics common to corporations and were thus
    subject to taxation as corporations under the federal tax
    code.” Littriello v. United States, 
    484 F.3d 372
    , 375 (6th
    Cir. 2007)). These characteristics, under the regulations,
    included: “(i) [a]ssociates, (ii) an objective to carry on busi-
    ness and divide the gains therefrom, (iii) continuity of life,
    (iv) centralization of management, (v) liability for corporate
    debts limited to corporate property, and (vi) free transfera-
    bility of interests.” 25 Fed. Reg. at 10,929–30.
    The modern regulations attempted to simplify the en-
    tity classification rules. See 61 Fed. Reg. at 66,584 (“The
    existing regulations for classifying business organizations
    as associations (which are taxable as corporations under
    section 7701(a)(3)) or as partnerships under section
    7701(a)(2) are based on the historical differences under lo-
    cal law between partnerships and corporations. Treasury
    and the IRS believe that those rules have become increas-
    ingly formalistic. This document replaces those rules with
    a much simpler approach that generally is elective.”). Un-
    der these regulations, a corporation means, inter alia, “[a]
    business entity organized under a Federal or State stat-
    ute . . . if the statute describes or refers to the entity as
    6           CHARLESTON AREA MEDICAL CTR. v. UNITED STATES
    incorporated or as a corporation, body corporate, or body
    politic.” 26 C.F.R. § 301.7701-2(b)(1).
    C. Treasury’s Notice
    On March 1, 2018, the IRS issued a notice regarding an
    entirely different section of the Code—Section
    1061(c)(4)(A). Internal Revenue Service, IRS Bull. No.
    2018-12 at 443, Guidance Under Section 1061, Partnership
    Interests Held in Connection with Performance of Services
    (Mar. 19, 2018) (hereinafter, “Notice”). Section 1061 gen-
    erally concerns partnership interests held in connection
    with performance of services and excludes from the term
    “applicable partnership interest” “any interest in a part-
    nership directly or indirectly held by a corporation.” The
    Notice announces that the IRS and Treasury “intend to is-
    sue regulations providing guidance on the application of
    section 1061” and that “those regulations will provide that
    the term ‘corporation’ for purposes of section
    § 1061(c)(4)(A) does not include an S corporation.” 
    Id. II. PROCEDURAL
    HISTORY
    The Taxpayers are non-stock, not-for-profit, § 501(c)(3)
    organizations incorporated in and under the laws of West
    Virginia. Although generally exempt from federal income
    tax, the Taxpayers are not exempt from taxes on “wages”
    from “employment” under the Federal Insurance Contribu-
    tions Act (“FICA”). “Employment” under FICA has a broad
    definition but excepts, for example, service performed in
    the employ of a school by a student who is regularly en-
    rolled and attending classes at the same school. 26 U.S.C.
    § 3121(b)(10).
    In 2010, the IRS administratively determined that
    medical residents fall within that exception to “employ-
    ment” and applied this determination retroactively. The
    IRS issued tax refunds to the Taxpayers, who had paid
    FICA taxes on medical residents for twenty-nine quarterly
    tax periods during the 1995 to 2005 taxable years. The IRS
    CHARLESTON AREA MEDICAL CTR. v. UNITED STATES              7
    paid interest on these tax refunds to the Taxpayers by ap-
    plying the interest rate for corporations under § 6621(a)(1).
    The Taxpayers contend that, if the IRS had used the inter-
    est rate for noncorporations under § 6621(a)(1), they would
    have received approximately $1.9 million in additional
    statutory interest. The Taxpayers now seek to recover over
    $2 million in total—the $1.9 million in additional statutory
    interest plus interest. J.A. 2.
    A. Related Case
    The Taxpayers first filed an action with a third plain-
    tiff, Wichita Center for Graduate Medical Education, in the
    District of Kansas on February 26, 2016. The district court
    ultimately dismissed the Taxpayers’ case for lack of venue,
    leaving Wichita Center as the only remaining plaintiff.
    Wichita Ctr. for Graduate Med. Educ. v. United States, No.
    16-1054-JTM, 
    2016 WL 4000934
    (D. Kan. July 26, 2016).
    It later granted summary judgment on the merits for the
    government, ruling that the term “corporation” as it ap-
    pears in § 6621(a)(1) includes nonprofit entities. Wichita
    Ctr. for Graduate Med. Educ. v. United States, No. 16-1054-
    JTM, 
    2017 WL 6055708
    (D. Kan. Dec. 7, 2017). Wichita
    Center appealed, and the Tenth Circuit affirmed consistent
    with the decisions of the three other circuits that addressed
    this issue before it. Tenth 
    Circuit, 917 F.3d at 1227
    .
    B. The Claims Court’s Decision
    After the district court dismissed the Taxpayers’
    claims, they, along with 290 similarly-situated entities,
    tried again, this time by filing an action at the Claims
    Court in October 2017. The government moved for judg-
    ment on the pleadings on March 26, 2018, arguing that the
    IRS correctly applied the lower interest rate to the Taxpay-
    ers. The Taxpayers later moved for summary judgment
    and class certification. The Claims Court granted the gov-
    ernment’s motion for judgment on the pleadings, denied
    Charleston Area’s motion for summary judgment, and
    thereby denied Charleston Area’s motion for class
    8           CHARLESTON AREA MEDICAL CTR. v. UNITED STATES
    certification as moot. Charleston Area Med. Ctr., 138 Fed.
    Cl. at 632–33.
    Regarding the merits, the Claims Court found that the
    term “corporation” as it appears in § 6621(a)(1) includes
    nonprofit entities like the Taxpayers here. It reasoned that
    common usage, the Code’s definition of the term in
    § 7701(a)(3), the structure of § 6621(a)(1), and the use of
    the term “corporation” in the Code as a whole “all indicate
    that the term ‘corporation’ in . . . § 6621 plainly encom-
    passes both for-profit and not-for-profit corporations.” 
    Id. at 631.
    The Claims Court also rejected the Taxpayers’
    counterargument, based on the Kintner Regulations and
    the IRS Notice of March 1, 2018, that the term “corpora-
    tion” in § 6621(a)(1) does not include nonprofit entities.
    The Taxpayers appeal the Claim Court’s determination
    on the merits as well as its decision to dismiss as moot the
    Taxpayers’ motion for class certification. We have jurisdic-
    tion pursuant to 28 U.S.C. § 1295(a)(3).
    III. DISCUSSION
    We conclude that the Taxpayers are corporations under
    § 6621 and that the Claims Court properly dismissed as
    moot the Taxpayers’ motion for class certification.
    A. The Taxpayers are “Corporations”
    under § 6621(a)(1)
    As a threshold matter, we address the definition of
    “corporation” contained in § 7701(a)(3). Typically, “[s]tat-
    utory definitions control the meaning of statutory words.”
    Burgess v. United States, 
    553 U.S. 124
    , 129 (2008). Where
    a statute provides an explicit definition, we must follow
    that definition even if it varies from the term’s customary
    meaning. Digital Realty Tr., Inc. v. Somers, 
    138 S. Ct. 767
    ,
    776 (2018). Here, § 7701(a)(3) of the Code is a definitional
    statute that defines “corporation” as a term that “includes
    associations, joint-stock companies, and insurance compa-
    nies.” 
    Id. (emphasis added).
    It is undisputed that medical
    CHARLESTON AREA MEDICAL CTR. v. UNITED STATES              9
    centers like the Taxpayers in this case do not fall into any
    of these three categories. See Sixth 
    Circuit, 833 F.3d at 674
    . But, while a definition that declares what a term
    “means” excludes any unstated meaning, a definition that
    states what a term “includes” is open-ended. See 
    Burgess, 553 U.S. at 130
    (quoting Colautti v. Franklin, 
    439 U.S. 379
    ,
    392–93 n.10 (1979)). Given that § 7701(c) uses the inclu-
    sive word, “includes,” the mere fact that the Taxpayers do
    not fall into the enumerated categories does not foreclose
    the possibility that they are corporations. And, “[i]n the
    absence of a statutory definition to the contrary, [we may]
    assume that Congress adopts the customary meaning of
    the terms it uses.” Sixth 
    Circuit, 833 F.3d at 674
    (citing
    Morissette v. United States, 342 U.S 246, 263 (1952)).
    The Taxpayers argue that we may not look to the cus-
    tomary meaning of “corporation,” because § 7701(a)(3) re-
    solves the issue presented. First, they contend that, under
    the statutory canons of noscitur a sociis and/or ejusdem
    generis, 1 § 7701(a)(3) excludes nonprofits from the defini-
    tion of “corporation.” Specifically, the Taxpayers contend
    that, because § 7701(a)(3) enumerates categories that are
    necessarily for-profit, such as “joint-stock companies[] and
    insurance companies,” the definitional statute cannot be
    extended to cover nonprofit entities. Indeed, “a word is
    known by the company it keeps.” Yates v. United States,
    
    135 S. Ct. 1074
    , 1085 (2015).
    1    Both canons are related and differ only in nuanced
    ways. While both “canons require identifying a common
    trait that links all the words in a statutory phrase,” nosci-
    tur a sociis is the doctrine applicable here. Yates v. United
    States, 
    135 S. Ct. 1074
    , 1097 (2015) (Noscitur a sociis “ad-
    vises that words grouped in a list be given similar mean-
    ings.”). According to the Taxpayers, the common trait
    among the enumerated categories here is that they are all
    for profit entities.
    10          CHARLESTON AREA MEDICAL CTR. v. UNITED STATES
    But the Taxpayers’ argument fails because, although
    certain enumerated objects in § 7701(a)(3) may be strictly
    for-profit entities, the section also enumerates “associa-
    tions.” Associations are not strictly for-profit entities and
    the Taxpayers do not suggest otherwise. Appellants’ Br. at
    12–13 (identifying only “joint-stock companies” and “insur-
    ance companies” as for-profit and failing to address
    whether “associations” are for-profit); see also 26 C.F.R. §
    29.3797-2 (1949) (“The term ‘association’ is not used in the
    Internal Revenue Code in any narrow or technical sense.
    It includes any organization, created for the transaction of
    designated affairs, or the attainment of some object, which,
    like a corporation, continues notwithstanding that its
    members or participants change, and the affairs of which,
    like corporate affairs, are conducted by a single individual,
    a committee, a board, or some other group, acting in a rep-
    resentative capacity.”). This indicates that the definitional
    statute contemplates a broader definition of “corporation”
    that is not limited to for-profit entities.
    Second, the Taxpayers argue that previous versions of
    § 7701(a)(3) limited the definition of “corporation” to only
    for-profit entities and that the amendment resulting in the
    current version was not meant to expand the meaning to
    include nonprofit entities. The language in § 7701(a)(3)
    originated in the Revenue Act of 1916, 39 Stat. 756, 789.
    Section 406 of that Act imposed an excise tax on “[e]very
    corporation, joint-stock company or association, now or
    hereafter organized in the United States for profit and hav-
    ing a capital stock represented by shares, and every insur-
    ance company.” 
    Id. (emphasis added).
         In the Revenue Act of 1918, Congress enacted
    § 7701(a)’s predecessor, which recited the exact same lan-
    guage as the current version. Accordingly, it dropped from
    Section 406 of the 1916 Act the phrase “now or hereafter
    organized in the United States for profit and having a cap-
    ital stock represented by shares,” and added the word “in-
    cludes” before enumerating the above-discussed categories
    CHARLESTON AREA MEDICAL CTR. v. UNITED STATES                11
    that qualify as corporations. The Taxpayers argue that
    Congress’s use of similar language from the 1916 Act in the
    1918 Act demonstrates that corporations should presently
    be limited to for-profit entities just as they were in the 1916
    Act.
    But the changes between the language in the two Acts
    actually cut against the Taxpayers’ argument. Congress
    removed the limiting phrase “now or hereafter organized in
    the United States for profit . . .” and added the inclusive
    word, “includes.” This demonstrates that Congress meant
    to expand the definition of corporation in the 1918 Act. See
    Second 
    Circuit, 809 F.3d at 88
    (finding that the § 7701(a)
    “serve[s] to expand the federal tax law meaning of ‘corpo-
    ration’ beyond entities that would ordinarily fall under the
    term; it offers no hint that Congress intended to contract
    the ordinary meaning of the term in any way.”). Indeed,
    that the 1916 Act included language specifying that the
    joint-stock companies and associations included in the sec-
    tion must be for-profit indicates that such companies and
    associations are not necessarily for-profit and further
    weakens the Taxpayer’s reliance on the noscitur a sociis
    canon of statutory interpretation.
    Because the definitional statute does not resolve the
    question of whether nonprofits are corporations, we next
    consider if the customary meaning of the term extends to
    nonprofit entities. We conclude that it does. The historical,
    common law understanding of “corporation” as well as new
    and old dictionaries indicate that nonprofit entities can be
    corporations. The Supreme Court held in 1819 that Dart-
    mouth College is a corporation. Trs. of Dartmouth Coll. v.
    Woodward, 
    17 U.S. 518
    , 636 (1819) (“Being the mere crea-
    ture of law, [a corporation] possesses only those properties
    which the charter of its creation confers upon it, either ex-
    pressly, or as incidental to its very existence.”). As the
    Sixth Circuit noted, the Court’s holding in Dartmouth Col-
    lege rested on so firm a foundation that “permitting a col-
    lege to be treated as a corporation [] might have been called
    12           CHARLESTON AREA MEDICAL CTR. v. UNITED STATES
    a cliché” at that time. Sixth 
    Circuit, 833 F.3d at 674
    . There
    can be no doubt that the historical common law under-
    standing of “corporation” extended to nonprofit entities
    such as the Taxpayers at issue here. See generally 
    id. at 674–75
    (collecting views of Edward Coke (1612), Chief Jus-
    tice Marshall (1819), Justice Joseph Story (1833), and Ed-
    mund Seymour (1903)). Nor can there be any doubt that
    new and old dictionaries similarly define “corporation.” See
    generally 
    id. at 675–76
    (collecting definitions from lay dic-
    tionaries, including Oxford English Dictionary (2016) and
    Webster’s New Int’l Dictionary (1934), as well as legal dic-
    tionaries, including the 1910 and 2014 editions of Black’s
    Law Dictionary).
    Finally, other circuits have held that an entity incorpo-
    rated under state law, like the Taxpayers in this case, is a
    corporation within the meaning of the Code. See, e.g.,
    O’Neil v. United States, 
    410 F.2d 888
    , 896 (6th Cir. 1969);
    United States v. Empey, 
    406 F.2d 157
    , 169–70 (10th Cir.
    1969). Thus, the ordinary meaning of the word “corpora-
    tion” extends to nonprofit entities.
    The ordinary meaning of “corporation” is also con-
    sistent with its use in the Code. As the Sixth Circuit noted,
    there are “three basic types of corporations addressed in
    the Code: nonprofit corporations covered by subchapter F;
    certain for-profit corporations covered by subchapter C;
    and certain for-profit corporations covered by subchapter
    S.” Sixth 
    Circuit., 833 F.3d at 676
    . This demonstrates that
    Congress used the generic definition of “corporation”—
    which includes both for-profit and nonprofit entities
    alike—in § 6621, because in each of these three subchap-
    ters, the drafters refer to the entities as “corporations.” 
    Id. For example,
    section 501, which addresses nonprofit enti-
    ties that are generally exempt from federal income tax, still
    refers to those nonprofit entities as “corporations.” 
    Id. In fact,
    “[t]he word ‘corporation’ is used approximately fifty
    times throughout § 501.” 
    Id. Other sections
    of the Code,
    including sections 1381(a)(2)(A), 2522(b)(2), 12(1),
    CHARLESTON AREA MEDICAL CTR. v. UNITED STATES                13
    3121(h)(5), 1504(b)(1), and 1(h)(11)(B)(ii)(I), all treat these
    nonprofit entities as corporations and then specifically ex-
    clude them from coverage. 2 
    Id. The Taxpayers
    raise various counterarguments—none
    of which we find persuasive. They contend that the in pari
    materia canon of construction and principles of symmetry
    require that we read § 6621(a)(1)’s provisions governing
    overpayments symmetrically with § 6621(c)(3)’s provisions
    governing underpayments. As noted above, the flush lan-
    guage in subsection (a)(1) begins, “[t]o the extent that an
    overpayment of tax by a corporation for any taxable period
    (as defined in subsection (c)(3), applied by substituting
    ‘overpayment’ for ‘underpayment’),” and cross-references
    subsection (c)(3). Subsection (c)(3), in turn, defines the
    term “large corporate underpayment” as “any underpay-
    ment of a tax by a C corporation.” 
    Id. (emphasis added).
    According to the Taxpayers, this definition limits the
    meaning of “corporation” in subsection (a)(1) to only C cor-
    porations. In support of this argument, the Taxpayers rely
    on the Second Circuit’s decision in Exxon Mobil Corp. v.
    Commissioner, 
    689 F.3d 191
    , 195 n.7 (2d Cir. 2012), in
    which, according to the Taxpayers, the Second Circuit held
    that interest rates on overpayments must be symmetrical
    with interest rates on underpayments.
    But the Second Circuit in Exxon did not set out such a
    broad principle; rather, it acknowledged the opposite—that
    interest rates for underpayments are higher than interest
    2   The Taxpayers counter that “the court ignored
    hundreds of instances in which the unadorned term [corpo-
    ration] encompasses only for-profit entities, such as S or C
    corporations.” Appellants’ Br. at 11. But the Taxpayers do
    not provide any such examples or citations and admit that
    they did not “undertake[] an exhaustive survey to deter-
    mine the exact number of enactments or amendments . . .
    that included the term ‘corporation.’” Appellants’ Br. at 21.
    14          CHARLESTON AREA MEDICAL CTR. v. UNITED STATES
    rates for overpayments. 
    Id. Regardless, principles
    of sym-
    metry cannot override the plain text of the statute. The
    other circuits that have considered this argument agree.
    See Sixth 
    Circuit, 833 F.3d at 678
    (“If the (c)(3) definition
    of ‘large corporate underpayment’ returns to (a)(1), that
    means the statute says: ‘To the extent that an overpayment
    of tax by a C corporation over $100,000 for any taxable pe-
    riod exceeds $10,000 . . . .’ Because $100,000 always ex-
    ceeds $10,000, that would make the dependent clause of
    the flush language in (a)(1) a needlessly confusing append-
    age. Congress deserves more credit than that.”); Second
    
    Circuit, 809 F.3d at 92
    (“By asking us to read ‘C’ into sub-
    section (a)(1), [the taxpayer] seeks to have the rule of in
    pari materia (insofar as it applies at all) override another
    canon of interpretation, namely, the rule that ‘[w]here Con-
    gress includes particular language in one section of a stat-
    ute but omits it in another section of the same Act, it is
    generally presumed that Congress acts intentionally and
    purposely in the disparate inclusion or exclusion.’” (altera-
    tion in original) (quoting Russello v. United States, 
    464 U.S. 16
    , 23 (1983))); Seventh 
    Circuit, 854 F.3d at 933
    (“[T]he dis-
    tinction between ‘corporation’ in subsection (a) and ‘C cor-
    poration’ in subparagraph (c)(3)(A) implies a different
    meaning. A presumption that a single word means the
    same thing throughout a statute goes together with a pre-
    sumption that different words mean different things.”).
    In essence, the Taxpayers’ argument amounts to one of
    policy—that a taxpayer should not have to pay a higher in-
    terest rate for underpayments of taxes than the govern-
    ment must pay for refunds on overpayments of taxes.
    While the outcome may seem unfair, it is one mandated by
    the text of the statute and thus can only be rectified by fu-
    ture amendments to the statutory text. Azar v. Allina
    Health Servs., 
    139 S. Ct. 1804
    , 1815 (2019) (“That leads us
    to the government’s final redoubt: a policy argument. But
    as the government knows well, courts aren’t free to rewrite
    clear statutes under the banner of our own policy concerns.
    CHARLESTON AREA MEDICAL CTR. v. UNITED STATES               15
    If the government doesn’t like Congress’s notice-and-com-
    ment policy choices, it must take its complaints there.”).
    The Taxpayers also contend that the Kintner regula-
    tions, replaced by the modern regulations in 1997, support
    their contention that the term “corporation” does not con-
    template nonprofit entities. As noted above, the Kintner
    regulations laid out certain characteristics common to cor-
    porations. Each of these characteristics, according to the
    Taxpayers, necessarily excluded nonprofit entities—
    “(i) [a]ssociates, (ii) an objective to carry on business and
    divide the gains therefrom, (iii) continuation of life,
    (iv) centralization of management, (v) liability for corpo-
    rate debts limited to corporate property, and (vi) free trans-
    ferability of interests.” 26 C.F.R. § 301.7701-2(b)(1). The
    Taxpayers argue that this is because each of these charac-
    teristics appears to contemplate generation of profits and
    thus are necessarily directed to for-profit entities. Though
    these regulations are no longer in effect, the Taxpayers
    contend that they were the governing definition for “corpo-
    ration” when Congress enacted § 6621 and thereby consti-
    tute the backdrop against which Congress legislated.
    The Taxpayers may very well be correct that the char-
    acteristics listed in the Kintner regulations seem directed
    to for-profit entities. They ignore, however, that the pur-
    pose of these regulations was to aid in classifying entities
    that were not incorporated under state law, but had certain
    other characteristics common to corporations and were
    thus still subject to taxation under the Code. Tenth 
    Circuit, 917 F.3d at 1226
    –27 (citing Kintner v. United States, 
    107 F. Supp. 976
    , 979 (D. Mont. 1952), aff’d, 
    216 F.2d 418
    (9th
    Cir. 1954) (holding that an “association” under state law
    could also be treated as a corporation for purposes of the
    Code because the Code may be more expansive than cate-
    gories enumerated under state law)); Littriello v. United
    States, 
    484 F.3d 372
    , 375 (6th Cir. 2007) (“The earlier reg-
    ulations had been developed to aid in classifying business
    associations that were not incorporated under state
    16          CHARLESTON AREA MEDICAL CTR. v. UNITED STATES
    incorporation statutes but that had certain characteristics
    common to corporations and were thus subject to taxation
    as corporations under the federal tax code.”). Here, the
    Taxpayers are incorporated under state law and thus
    would have been considered a corporation even in the era
    of the Kintner regulations.
    Finally, the Taxpayers argue that the Notice supports
    its interpretation of the statute. As stated above, the IRS
    issued a notice on March 1, 2018, which “announces that
    the [Treasury Department] and the [IRS] intend to issue
    regulations providing guidance on the application of sec-
    tion 1061 [of the Internal Revenue Code . . . [and] further
    announces that the Treasury Department and the IRS in-
    tend that those regulations will provide that the term ‘cor-
    poration’ for purposes of section 1061(c)(4)(A) does not
    include an S corporation.” J.A. at 169. The Taxpayers
    characterize this Notice as “formal administrative guid-
    ance” that “holds that the term ‘corporation’ does not . . .
    encompass S corporations but instead means ‘C corpora-
    tion.’” Appellant’s Br. at 39. According to the Taxpayers,
    the notice shows that “corporation” does not have a broad
    meaning.
    But, the Notice’s exclusion of an S corporation from the
    definition of “corporation” would be “for purposes of” §
    1061; the Notice does not purport to alter the meaning of
    “corporation” as it appears in § 6621. While we question
    whether the regulations described in the Notice, if codified,
    would be proper in view of the government’s position in this
    case that the Code incorporates the broad, common law
    meaning of “corporation,” we leave that issue for another
    day. Indeed, the Notice is just that—a Notice regarding
    regulations that do not yet, and may never, exist. The
    Claims Court declined “to express any views on whether
    the approach of some as-yet-to-be issued regulations is in-
    consistent with the government’s arguments in this case.”
    J.A. 9. We do the same here.

    B. The Motion for Class Certification is Moot
    The Taxpayers also argue that the Claims Court erred
    in denying its motion for class certification as moot. But
    we addressed this issue in Greenlee County v. United
    States, 
    487 F.3d 871
    (Fed. Cir. 2007). There, we noted that
    this court has “repeatedly found on appeal that issues re-
    lated to class certification were moot in light of our resolu-
    tion against the plaintiff of a motion to dismiss or for
    summary judgment.” 
    Id. at 880
    (citing Christopher Vill.,
    L.P. v. United States, 
    360 F.3d 1319
    , 1337–38 (Fed. Cir.
    2004); Gollehon Farming v. United States, 
    207 F.3d 1373
    ,
    1382 (Fed. Cir. 2000), overruled on other grounds by Fisher
    v. United States, 
    402 F.3d 1167
    (Fed. Cir. 2005); Greenbrier
    v. United States, 
    193 F.3d 1348
    , 1360 (Fed. Cir. 1999)). Ac-
    cordingly, we saw no reason to apply a different rule when
    it is the Claims Court that finds the issue moot. 
    Id. We also
    noted that “[n]othing in the Supreme Court’s
    decision in Eisen v. Carlisle & Jacquelin, 
    417 U.S. 156
    (1974), which held that the merits of the plaintiff’s claim
    should not be considered in ruling on class certification[,]
    requires that class certification be addressed before ruling
    on a motion to dismiss.” 
    Id. We reasoned
    that the “weight
    of authority after Eisen supports our conclusion that it was
    within the discretion of the Court of Federal Claims to find
    the class certification motion moot.” 
    Id. at 880
    –81. (cit-
    ing Kehoe v. Fid. Fed. Bank & Tr., 
    421 F.3d 1209
    , 1211 n.1
    (11th Cir. 2005) (finding no error in grant of summary judg-
    ment without resolving class certification); Curtin v.
    United Airlines, Inc., 
    275 F.3d 88
    , 92 (D.C. Cir. 2001)
    (same); Schweizer v. Trans Union Corp., 
    136 F.3d 233
    , 239
    (2d Cir. 1998) (“There is nothing in [Fed. R. Civ. P.] 23
    [which governs class certification] which precludes the
    court from examining the merits of plaintiff’s claims on a
    proper Rule 12 motion to dismiss or Rule 56 motion for
    summary judgment simply because such a motion precedes
    resolution of the issue of class certification.”). Thus, we
    18           CHARLESTON AREA MEDICAL CTR. v. UNITED STATES
    find that the Claims Court did not err in denying the Tax-
    payers’ motion for class certification as moot.
    CONCLUSION
    For the reasons stated above, we affirm the decision of
    the Claims Court.
