    Before: RIORDAN, P.J., and JANSEN and HOOD, JJ.
    PER CURIAM.
    I. INTRODUCTION
    In these 23 consolidated appeals,1 the plaintiffs are taxpayers who respectively appeal as
    of right orders granting summary disposition in each case to defendant, the Michigan Department
    of Treasury. Each appeal raises common issues challenging the Court of Claims’ holding that
    the mandatory apportionment provision of the Single Business Tax Act (“SBTA”), MCL 208.1
    et seq.,2 impliedly repealed a provision of Michigan’s enactment of the Multistate Tax Compact
    (“the Compact”), MCL 205.581 et seq.,3 which allowed multistate taxpayers to apportion their
    tax base using an equally weighted, three-factor formula set forth in the Compact. Plaintiffs
    further contend that an implied repeal of the Compact’s election provision violates the terms of
    the Compact—which, according to plaintiffs, was binding on subsequent legislatures—and
    violates state and federal constitutional provisions. Additionally, in Docket No. 327251, plaintiff
    Johnson Matthey, Inc. (“Johnson Matthey”) also argues that it was entitled to apportion its
    Michigan Business Tax (“MBT”) base pursuant to the Compact apportionment formula, and that
    the retroactive repeal of the Compact by 
    2014 PA 282
    violated the terms of the Compact and
    various constitutional provisions.
    In cross-appeals in all of the cases except for Cambrex Charles City, Inc v Dep’t of
    Treasury (Docket No. 327330), and as alternative grounds for affirmance in all of the cases,
    defendant argues that the SBT is not an income tax under the apportionment election provision
    of the Compact and that the retroactive repeal of the Compact by 
    2014 PA 282
    barred plaintiffs
    from asserting their respective SBT refund claims.
    Because we conclude that the SBTA did not impliedly repeal the Compact apportionment
    election provision, we reverse and remand for further proceedings consistent with this opinion.

    The entire SBTA was repealed by 
    2006 PA 325
    and replaced with the Michigan Business Tax
    Act (“MBTA”). All subsequent references to the SBTA, MCL 208.1 et seq., shall incorporate
    this repeal.

    The Compact was expressly and retroactively repealed by 
    2014 PA 282

    January 1, 2008. All subsequent to the Compact should similarly incorporate this later explicit
    repeal.

    II. HISTORICAL BACKGROUND AND PROCEDURAL POSTURE4
    Plaintiffs in the present cases are claiming SBT refunds for at least one tax year between
    2005 and 2007. In particular, plaintiffs seek to reduce their SBT liability for the tax years at
    issue by apportioning their income through the equally weighted, three-factor apportionment
    formula provided in the Compact rather than the three-factor formula provided in the SBTA,
    which weighted the sales factor of the formula more heavily. As the Court of Claims stated, the
    principal issue in these cases is “whether the SBT apportionment formula for the tax years in
    question is mandatory or whether an SBT taxpayer may elect to apportion its tax base to
    Michigan using the Compact’s equally weighted, three-factor apportionment formula.”
    A. THE SBTA
    From January 1, 1976, until its repeal effective December 31, 2007, the SBTA governed
    the taxation of business activity in Michigan. See 
    1975 PA 228
    ; 
    2006 PA 325
    . Under the
    SBTA, a tax base was calculated by beginning with a business’s federal taxable income and then
    adding back compensation, depreciation, and other factors, as well as making other adjustments.
    See Trinova Corp v Mich Dep’t of Treasury, 
    498 U.S. 358
    , 366-367; 
    111 S. Ct. 818
    ; 
    112 L. Ed. 2d 884
    (1991) (Trinova II). Throughout its history, the SBT was apportioned using a three-factor
    formula consisting of payroll, property, and sales. As the Court of Claims explained in its
    opinion, this formula originally weighted the three factors equally, in accordance with previous
    business taxes in Michigan and the nearly universal practice of other states at the time.
    However, in later years, many states moved away from an equally weighted, three-factor formula
    by more heavily weighting the sales factor. Following this trend, the Michigan Legislature
    abandoned uniform apportionment and began to more heavily weight the sales factor in 1991.
    See 
    1991 PA 77
    . Subsequent amendments continued to weigh the sales factor even more
    heavily. For tax years 1999 through 2005, the sales factor was weighted at 90%, and for 2006
    and 2007, the sales factor was weighted at 92.5%. See 
    1995 PA 283
    ; 
    2005 PA 295
    ; MCL
    208.45a(1)(c), (2)(c), repealed by 
    2006 PA 325
    .
    B. THE COMPACT
    The Compact originally was adopted by seven states in 1967. The Michigan Legislature
    adopted the Compact provisions effective in 1970. See 
    1969 PA 343
    . While Congress never
    approved the Compact, it was upheld against constitutional challenges. See US Steel Corp v
    Multistate Tax Comm, 
    434 U.S. 452
    ; 
    98 S. Ct. 799
    ; 
    54 L. Ed. 2d 682
    (1978). The Compact
    established the Multistate Tax Commission (“the Commission”), but each state remained free to
    adopt or reject the Commission’s rules and regulations and remained free to withdraw from the
    Compact at any time. See 
    id. at 473.
    Most relevant to this appeal, Article IV of the Compact set
    forth a three-factor apportionment formula that equally weighted property, payroll, and sales
    factors. MCL 205.581, Art IV(9). Article III of the Compact provided that a taxpayer subject to
    4
    In summarizing the historical development of the law in Michigan, we rely heavily on the
    Court of Claims’ comprehensive and well-written recitation of the relevant legal background in
    its opinion issued in EMCO Enterprises, Inc v Dep’t of Treasury (Docket No. 327313).

    an income tax “in two or more party states may elect to apportion and allocate his income in the
    manner provided by the laws of such states . . . without reference to this compact, or may elect to
    apportion and allocate in accordance with article IV.” MCL 205.581, Art III(1).
    On May 25, 2011, the Michigan Legislature passed 
    2011 PA 40
    , which amended the
    Compact so that a multistate taxpayer subject to the MBTA or the income tax act of 1967 could
    not elect the Compact apportionment formula beginning January 1, 2011. Then, on September
    11, 2014, our Legislature enacted 
    2014 PA 282
    , which retroactively repealed the Compact
    provisions effective January 1, 2008, and mandated the use of a single sales-factor
    apportionment formula for the purpose of calculating the MBT and the corporate income tax. As
    the Court of Claims explained in EMCO:
    PA 282 thus amended the MBT to express the “original intent” of the
    Legislature with regard to (1) the repeal of the Compact provisions, (2)
    application of the MBT’s apportionment provision under MCL 208.1301, and (3)
    the intended effect of the Compact’s election provision under MCL 205.581. The
    effect of the amendments, as written, retroactively eliminates a taxpayer’s ability
    to elect a three-factor apportionment formula in calculating tax liability under
    both the MBT and the [corporate income tax].
    C. THE COURT OF CLAIMS’ DECISION
    In one of the present appeals, EMCO Enterprises, Inc v Dep’t of Treasury (Docket No.
    327313) (“EMCO”), the Court of Claims issued a 29-page opinion addressing the plaintiff’s
    claims and granting summary disposition in favor of defendant pursuant to MCR 2.116(I)(2). In
    summarizing its decision, the Court of Claims stated:
    The Court, in fulfilling its duty to ascertain and apply the intent of the
    Legislature, finds that the taxpayer is required to use the apportionment formulas
    mandated under the SBTA for the tax years in question, and is not entitled to elect
    a different apportionment formula under the Compact. Though the SBT is an
    income tax within the meaning of the Compact, future legislatures were not bound
    by the policies of the legislature that enacted 
    1969 PA 343
    . The purpose of state
    tax uniformity as embedded in both the Compact’s apportionment elective
    provision by the 1969 legislature, and the SBTA’s equally weighted, three-factor
    apportionment formula as originally enacted by the 1975 legislature, is not
    consistent with the purpose of later amendments made to apportionment formulas
    by the Legislature. Under traditional rules of statutory construction, the
    apportionment formula under the SBTA for the tax years in question must control.
    More specifically, in its EMCO opinion, the Court of Claims concluded that the Compact was
    advisory and did not bind future legislatures, that the Compact was not a binding contract under
    Michigan law, and that the Legislature was therefore free to mandate the use of apportionment
    formulas that deviated from the formula set forth in the Compact. The court further determined
    that the SBTA in effect during the tax years at issue conflicted with the Compact apportionment
    election provision by requiring the use of a different apportionment formula from that provided
    in the Compact, and that these provisions could not be harmonized. Thus, the Court of Claims
    -9-
    concluded that the SBTA apportionment provision was controlling and had impliedly repealed
    the Compact’s apportionment election provision. Further, the court rejected arguments that
    denying plaintiffs the right to elect the Compact’s equally weighted, three-factor apportionment
    formula violated the Commerce and Due Process Clauses of the United States Constitution.
    In the remaining appeals, the Court of Claims entered essentially identical orders in each
    case granting summary disposition in favor of defendant pursuant to MCR 2.116(I)(1) on the
    basis of the reasoning in the EMCO opinion.5
    III. STANDARD OF REVIEW
    A trial court’s decision to grant summary disposition pursuant to MCR 2.116(I)(1) is
    reviewed de novo. Gillette Commercial Operations North America & Subsidiaries v Dep’t of
    Treasury, ___ Mich App ___, ___; ___ NW2d ___ (2015) (Docket Nos. 325258 et al); slip op at
    16, lv pending (“Gillette”). MCR 2.116(I)(1) provides, “If the pleadings show that a party is
    entitled to judgment as a matter of law, or if the affidavits or other proofs show that there is no
    genuine issue of material fact, the court shall render judgment without delay.”6 We also review
    de novo issues involving statutory interpretation as well as constitutional questions. Gillette, ___
    Mich App at ___; slip op at 16.
    IV. IMPLIED REPEAL OF THE COMPACT ELECTION PROVISION
    The central issue in this case is whether the Court of Claims erred in concluding that the
    SBTA’s mandatory apportionment provision impliedly repealed the Compact’s apportionment
    election provision for the tax years at issue (i.e., 2005, 2006, and 2007). We agree with plaintiffs
    5
    In Johnson Matthey (Docket No. 327251), the Court of Claims’ order also included language
    referencing the Court of Claims’ opinions in two other cases holding that 
    2014 PA 282
    negated
    the plaintiffs’ claims for refunds under the MBTA. The two cases were Yaskawa America, Inc v
    Dep’t of Treasury (Docket No. 325475), and Ingram Micro, Inc v Dep’t of Treasury (Docket No.
    325507), both of which were part of the 50 consolidated appeals that were the subject of this
    Court’s recent published opinion in Gillette Commercial Operations North America &
    Subsidiaries v Dep’t of Treasury, ___ Mich App ___; ___ NW2d ___ (2015) (Docket Nos.
    325258 et al), lv pending, which is discussed later in this opinion.
    6
    The Court of Claims’ opinion in EMCO stated that it was granting summary disposition to
    defendant pursuant to MCR 2.116(I)(2), which states: “If it appears to the court that the opposing
    party, rather than the moving party, is entitled to judgment, the court may render judgment in
    favor of the opposing party.” However, the orders in the other 22 consolidated cases stated that
    summary disposition was granted to defendant pursuant to MCR 2.116(I)(1). The issues raised
    in these cases concern questions of law. As such, whether defendant is entitled to summary
    disposition is a matter of law. Thus, we conclude that review under MCR 2.116(I)(1) is proper.
    It is well settled that regardless of the subrule cited by the trial court in granting summary
    disposition, this Court will review the court’s order under the correct subrule. See Spiek v Dep’t
    of Transp, 
    456 Mich. 331
    , 338 n 9; 572 NW2d 201 (1998).

    and hold that the SBTA did not impliedly repeal the Compact’s apportionment election
    provision.
    A. BACKGROUND LAW
    “When interpreting statutory language, our obligation is to ascertain the legislative intent
    that may reasonably be inferred from the words expressed in the statute.” Koontz v Ameritech
    Servs, Inc, 
    466 Mich. 304
    , 312; 645 NW2d 34 (2002). “Courts must give effect to every word,
    phrase, and clause in a statute, and must avoid an interpretation that would render any part of the
    statute surplusage or nugatory.” 
    Id. Statutory language
    must be read in context, and undefined

    Treasury, 
    308 Mich. App. 362
    , 370; 863 NW2d 387 (2014). “If the language of the statute is

    In general, “repeals by implication are disfavored.” Wayne Co Prosecutor v Dep’t of
    Corrections, 
    451 Mich. 569

    if the Legislature had intended to repeal a statute or statutory provision, it would have done so
    explicitly.” 
    Id. When presented
    with a claim that two statutes conflict, a court must endeavor to
    construe the statutes harmoniously if possible. 
    Id. [R]epeal by
    implication will not be found if any other reasonable construction
    may be given to the statutes, such as reading in pari materia two statutes that
    share a common purpose or subject, or as one law, even if the two statutes were
    enacted on different dates and contain no reference to one another. However, a
    repeal of a statute may be inferred in two instances: (1) where it is clear that a
    subsequent legislative act conflicts with a prior act; or (2) when a subsequent act
    of the Legislature clearly is intended to occupy the entire field covered by a prior
    enactment. [City of Kalamazoo v KTS Indus, Inc, 
    263 Mich. App. 23
    , 36-37; 687

    Similarly, the Michigan Supreme Court previously explained, “[I]f the provisions of a
    later statute are so at variance with those of an earlier act, or a part thereof, that both cannot be
    given effect[,] then the later enactment control[s] and there is a repeal by implication. In such a
    case it must be presumed that the legislature intended a repeal.” Jackson v Mich Corrections
    Comm, 
    313 Mich. 352
    , 357; 21 NW2d 159 (1946). “Repeals by implication are not favored, but
    do happen, and, when clear, must be given effect.” 
    Id. (quotation marks
    and citation omitted).
    Therefore, “if there is such repugnance that both [statutes] cannot operate, then the last
    expression of the legislative will must control.”

    extent of the repugnancy, as a repeal of the first . . . .”

    rule that where two laws in pari materia are in irreconcilable conflict, the one last enacted will
    control or be regarded as an exception to or qualification of the prior statute.”). Notably, “when
    faced with two statutes that bear on the same subject, our task is not to discern the most logical
    construction of the more recent statute, but to labor to permit the survival of both enactments if
    -11-

    B. ANALYSIS
    During the tax years at issue in this case, § 41 of the SBTA provided that “[a] taxpayer
    whose business activities are taxable both within and without this state, shall apportion his tax
    base as provided in this chapter.” MCL 208.41 (emphasis added). As previously discussed, for
    tax years prior to 1991, the SBTA prescribed an equally weighted, three-factor apportionment
    formula comprised of property, payroll, and sales factors. Beginning with the 1991 tax year,
    however, the SBTA required the sales factor to be weighted more heavily than the other factors,
    and the weight of the sales factor was further increased in later tax years by legislative
    amendments to the act. See MCL 208.45; MCL 208.45a. For the 2005 tax year, the sales factor
    was weighted at 90%. MCL 208.45a(1)(c). For the 2006 and 2007 tax years, the sales factor
    was weighted at 92.5%. MCL 208.45a(2)(c).
    To the contrary, during the tax years at issue, the Compact’s apportionment election
    provision stated:
    (1) Any taxpayer subject to an income tax whose income is subject to
    apportionment and allocation for tax purposes pursuant to the laws of a party state
    or pursuant to the laws of subdivisions in 2 or more party states may elect to
    apportion and allocate his income in the manner provided by the laws of such
    state or by the laws of such states and subdivisions without reference to this
    compact, or may elect to apportion and allocate in accordance with Article IV . . .
    . [MCL 205.581, Art III(1).]
    As 
    explained supra
    , article IV of the Compact set forth an equally weighted, three-factor
    apportionment formula comprised of property, payroll, and sales factors. MCL 205.581, Art
    IV(9). Thus, the Compact election “provision allow[ed] a taxpayer subject to an income tax to
    elect to use a party state’s apportionment formula or the Compact’s [equally weighted,] three-
    factor formula.” Int’l Business Machines Corp v Dep’t of Treasury, 
    496 Mich. 642
    , 653; 852
    NW2d 865 (2014) (opinion by VIVIANO, J.) (“IBM”).
    The Court of Claims correctly concluded that an apparent conflict exists between the
    language of the SBTA and the Compact election provision. Under § 41 of the SBTA, a
    multistate taxpayer “shall apportion his tax base as provided in this chapter.” MCL 208.41
    (emphasis added). “The Legislature’s use of the word ‘shall’ generally indicates a mandatory
    directive, not a discretionary act.” Smitter v Thornapple Twp, 
    494 Mich. 121
    , 136; 833 NW2d
    875 (2013). The SBTA apportionment formula for the tax years at issue weighted the sales
    factor more heavily than the other factors, MCL 208.45a(1)(c), (2)(c), and there is no language in
    the SBTA indicating that a taxpayer was permitted to use an apportionment formula other than
    the one provided in that chapter. By contrast, the language of the Compact allowed a taxpayer to
    choose the equally weighted, three-factor formula in the Compact. MCL 205.581, Arts III(1),
    IV(9). As the Court of Claims explained, “[b]ecause the SBTA during the tax years in question
    mandates the use of one apportionment formula, while the Compact provides for the
    discretionary use of another apportionment formula, the statutes are in apparent conflict.”
    -12-
    However, we disagree with the Court of Claims that the two statutes cannot be
    harmonized. Rather, we find persuasive the reasoning utilized in the lead opinion in 
    IBM, 496 Mich. at 651-662
    (opinion by VIVIANO, J.),7 concerning the interplay between the MBT and the
    Compact. Consistent with that analysis, we hold that it is possible to reasonably construe § 41 of
    the SBTA and Articles III(1) and IV(9) of the Compact in harmony with each other.
    The lead opinion explained,
    [W]here the intent of the Legislature is claimed to be unclear, it is our duty to
    proceed on the assumption that the Legislature desired both statutes to continue in
    effect unless it manifestly appears that such view is not reasonably plausible.
    Repeals by implication will be allowed only when the inconsistency and
    repugnancy are plain and unavoidable. We will construe statutes, claimed to be in
    conflict, harmoniously to find any other reasonable construction than a repeal by
    implication. Only when we determine that two statutes are so incompatible that
    both cannot stand will we find a repeal by implication. 
    [IBM, 496 Mich. at 651
    -
    652 (opinion by VIVIANO, J.) (quotation marks and footnotes omitted).]
    In attempting to find a harmonious construction, courts should consider all statutes addressing
    the same general subject matter as comprising part of one system.

    Michigan, 
    284 Mich. 521

    280 N.W. 35
    (1938). “Further, ‘[s]tatutes in pari materia, although
    in apparent conflict, should, so far as reasonably possible, be construed in harmony with each
    other, so as to give force and effect to each . . . .’ ” 
    IBM, 496 Mich. at 652
    (opinion by VIVIANO,
    J.) (alterations in original), quoting 
    Rathbun, 284 Mich. at 544
    .
    It is a well-established rule that in the construction of a particular statute, or in the
    interpretation of its provisions, all statutes relating to the same subject, or having
    the same general purpose, should be read in connection with it, as together
    constituting one law, although they were enacted at different times, and contain
    no reference to one another. The endeavor should be made, by tracing the history
    of legislation on the subject, to ascertain the uniform and consistent purpose of the
    legislature, or to discover how the policy of the legislature with reference to the
    subject-matter has been changed or modified from time to time. In other words,
    in determining the meaning of a particular statute, resort may be had to the
    established policy of the legislature as disclosed by a general course of legislation.
    With this purpose in view therefore it is proper to consider, not only acts passed at
    the same session of the legislature, but also acts passed at prior and subsequent
    sessions. [

    Because a majority of the justices in IBM did not agree on the implied-repeal analysis contained
    in the lead opinion, the lead opinion’s holding on that issue is not binding authority. See Burns v
    Olde Discount Corp, 
    212 Mich. App. 576

    , 569; 484 NW2d 408 (1992).

    Thus, the Compact’s election provision and § 41 of the SBTA should be construed together as
    statutes in pari materia because they share, like the Compact and the MBTA, “the common
    purpose of setting forth the methods of apportionment of a taxpayer’s multistate business
    income.” 
    IBM, 496 Mich. at 653
    (opinion by VIVIANO, J.).8
    In reviewing the statutes in pari materia, we conclude that the following reasoning,
    employed by the lead opinion in IBM with regard to the MBTA and the Compact, is equally
    applicable in this case:
    [T]he Compact’s election provision, by using the terms “may elect,” contemplates
    a divergence between a party state’s mandated apportionment formula and the
    Compact’s own formula—either at the time of the Compact’s adoption by a party
    state or at some point in the future. Otherwise, there would be no point in giving
    taxpayers an election between the two. In fact, reading the Compact’s election
    provision as forward-looking—i.e., contemplating the future enactment of a state
    income tax with a mandatory apportionment formula different from the
    Compact’s apportionment formula—is the only way to give meaning to the
    provision when it was enacted in Michigan. Viewed in this light, the [MBT’s]
    mandatory apportionment language may plausibly be read as compatible with the
    Compact’s election provision.
    8
    We recognize that the rule of in pari materia “does not permit the use of a previous statute to
    control by way of former policy the plain language of a subsequent statute . . . .” Voorhies v
    Faust, 
    220 Mich. 155
    , 157; 
    189 N.W. 1006
    (1922). However, neither the IBM lead opinion, nor
    our opinion in this case, effectively resolves the conflict between the MBT or the SBT in favor of
    the Compact, i.e., the earlier enacted statute, or permits the utilization of the apportionment
    provision in the Compact in such a way that contradicts the plain language of a subsequent
    statute. Rather, as explained in this opinion, we conclude that the apportionment provisions of
    the SBTA and the Compact can be read harmoniously.
    Additionally, we recognize that “the interpretive aid of the doctrine of in pari materia can
    only be utilized in a situation where the section of the statute under examination is itself
    ambiguous.” Tyler v Livonia Pub Sch, 
    459 Mich. 382
    , 392; 590 NW2d 560 (1999), citing
    
    Voorhies, 220 Mich. at 157
    ; see also In re Indiana Mich Power Co, 
    297 Mich. App. 332
    , 344; 824
    NW2d 246 (2012). However, this principle does not preclude the use of the doctrine in this case.
    Although the language of § 41 of the SBTA arguably may be unambiguous when read in
    isolation, the interpretation and construction of that section—or a determination of the
    applicability of that section on its own—is not at issue here. Rather, we are inescapably required
    to consider the effect of MCL 208.41 on the Compact election provision, which, in this case,
    clearly requires consideration of the statutes together in the context of the statutory scheme as a
    whole. Cf. KTS Indus, 
    Inc, 263 Mich. App. at 36-37
    (“[R]epeal by implication will not be found
    if any other reasonable construction may be given to the statutes, such as reading in pari materia
    two statutes that share a common purpose or subject, or as one law, even if the two statutes were
    enacted on different dates and contain no reference to one another.”).

    * * *
    Because the Legislature gave no clear indication that it intended to repeal
    the Compact’s election provision, we proceed under the assumption that the
    Legislature intended for both to remain in effect. After reading the statutes in
    pari materia, we conclude that a reasonable construction exists other than a repeal
    by implication. Under Article III(1) of the Compact, the Legislature provided a
    multistate taxpayer with a choice between the apportionment method contained in
    the Compact or the apportionment method required by Michigan’s tax laws. If a
    taxpayer elects to apportion its income through the Compact, Article IV(9)
    mandates that the taxpayer do so using a three-factor apportionment formula.
    Alternatively, if the taxpayer does not make the Compact election, then the
    taxpayer must use the apportionment formula set forth in Michigan’s governing
    tax laws. In this case, IBM’s tax base arose under the [MBT]. Had it not elected
    to use the Compact’s apportionment formula, IBM would have been required to
    apportion its tax base consistently with the mandatory language of the [MBT]—
    i.e., through the [MBT’s] sales-factor apportionment formula. Thus, we believe
    the [MBT] and the Compact are compatible and can be read as a harmonious
    whole. [Id. at 656-658 (opinion by VIVIANO, J.).]
    In the context of the instant case, the Legislature provided plaintiffs with a choice,
    through Article III(1) of the Compact, between the apportionment method contained in the
    Compact or the apportionment method required by the SBTA. If a taxpayer elects to apportion
    its income as provided by the Compact, Article IV(9) requires that the taxpayer do so using a
    three-factor apportionment formula. Alternatively, if the taxpayer does not elect the
    apportionment method under the Compact, then the taxpayer is required to use the apportionment
    formula set forth in the applicable tax laws. There is a reasonable construction that harmonizes
    the two statutes. Thus, the presumption against implied repeals has not been rebutted here. See
    
    id. at 660
    (“[B]ecause there is a presumption against implied repeals, it is our task to determine if
    there is any other reasonable construction that would harmonize the two statutes and avoid a
    repeal by implication.” [Footnotes omitted.]).
    The lead opinion in IBM also found that its conclusion that the Compact apportionment
    provision was not impliedly repealed was consistent with the development of Michigan tax law,
    concluding that a “review of the statutes in pari materia indicates a uniform and consistent
    purpose of the Legislature for the Compact’s election provision to operate alongside Michigan’s
    tax acts.” 
    Id. at 656.
    The opinion noted that the Legislature, despite its full knowledge of the
    Compact, left its election provision intact while repealing or amending other acts that were
    inconsistent with provisions concerning business taxation. 
    Id. at 657.
    Likewise, the opinion also
    noted the Legislature’s retroactive amendment of the Compact effective January 1, 2011, which
    did not apply to all tax years subject to the MBTA, in ascertaining the Legislature’s intent to
    keep the Compact’s provisions intact despite the enactment and amendment of the MBTA. 
    Id. at 658-659
    (discussing 
    2011 PA 40
    ).
    We acknowledge the enactment of 
    2014 PA 282
    , which provides, in pertinent part:
    -15-
    Enacting section 1. 
    1969 PA 343
    , MCL 205.581 to 205.589, is repealed
    retroactively and effective beginning January 1, 2008. It is the intent of the
    legislature that the repeal of 
    1969 PA 343
    , MCL 205.581 to 205.589, is to express
    the original intent of the legislature regarding the application of section 301 of
    the Michigan business tax act, 
    2007 PA 36
    , MCL 208.1301, and the intended
    effect of that section to eliminate the election provision included within section 1
    of 
    1969 PA 343
    , MCL 205.581, and that the 2011 amendatory act that amended
    section 1 of 
    1969 PA 343
    , MCL 205.581, was to further express the original
    intent of the legislature regarding the application of section 301 of the Michigan
    business tax act, 
    2007 PA 36
    , MCL 208.1301, and to clarify that the election
    provision included within section 1 of 
    1969 PA 343
    , MCL 205.581, is not
    available under the income tax act of 1967, 
    1967 PA 281
    , MCL 206.1 to 206.713.
    [Emphasis added.]
    Through 
    2014 PA 282
    , the Legislature clarified—contrary to the lead opinion’s conclusion in
    IBM—that it had intended to impliedly repeal the Compact when it enacted the MBT through
    
    2007 PA 36
    , and that this intent was further revealed by its subsequent express repeal of the
    Compact election provision, effective January 1, 2011, under 
    2011 PA 40
    .
    However, in clarifying its legislative intent, the Legislature included nothing in 
    2014 PA 282
    regarding the validity of the Compact election provision for multistate taxpayers subject to
    the SBTA before the effective date of the MBTA. In so doing, the Legislature left open the
    application of the Compact apportionment formula during tax years subject to the SBTA. If it so
    chose, the Legislature easily could have closed this door. Instead, it chose not to, and it is not
    our role to second guess its reasoning for not doing so. Thus, we conclude, consistent with the
    lead opinion’s analysis in IBM, that
    the Legislature, in enacting [and amending] the [SBTA], had full knowledge of
    the Compact and its provisions. Even with such knowledge on [multiple]
    occasions, the Legislature left the Compact’s election provision intact [with
    regard to the SBTA]. By contrast, the Legislature expressly repealed or amended
    other inconsistent acts regarding the taxation of businesses[, including its repeal
    of the Compact with regard to tax years subject to the MBTA]. Had the
    Legislature believed that the Compact’s election provision no longer had a place
    in Michigan’s tax system or conflicted with the purpose of the [SBTA], it could
    have taken the necessary action to eliminate the election provision. 
    [IBM, 496 Mich. at 657
    (opinion by VIVIANO, J.).]
    See also 
    id. at 659
    n 59 (“ ‘[T]he later express repeal of a particular statute may be some
    indication that the legislature did not previously intend to repeal the statute by implication.’ ”),
    quoting 1A Singer, Sutherland Statutory Construction (7th ed), § 23:11, p 485.
    Accordingly, especially in light of the Legislature’s clear expressions of intent regarding
    the express and implied repeal of the Compact in conjunction with the enactment of the MBTA,
    and the lack of any indication that § 41 of the SBTA was intended to repeal the apportionment
    election provision in the Compact, we assume that the Legislature intended for the Compact
    -16-
    election provisions to remain in effect alongside the SBTA. See 
    id. at 657.
    Additionally, as
    
    explained supra
    , the statutes may be reasonably construed in harmony. See 
    id. Thus, because
    a “repeal by implication will not be found if any other reasonable
    construction may be given to the statutes,” KTS 
    Indus, 263 Mich. App. at 36-37
    (emphasis
    added), the Court of Claims erred in concluding that the Compact’s election provision was
    impliedly repealed by the SBTA.
    V. THE BINDING NATURE OF THE COMPACT AND OTHER CONSTITUTIONAL
    CHALLENGES
    Next, plaintiffs raise a series of arguments regarding whether the Compact was binding
    on subsequent legislatures, whether the Compact was superior to statutory law, and whether an
    implied repeal of the Compact would violate various state and federal constitutional provisions.
    These claims are rooted in the Court of Claims’ conclusion that the Compact was impliedly
    repealed by the SBTA. As 
    explained supra
    , we hold that the SBTA did not impliedly repeal the
    Compact’s apportionment election provision. Thus, to the extent that plaintiffs assert that a
    repeal of the apportionment election provision of the Compact was impermissible or violated
    state and federal constitutional provisions, we need not address those claims in light of our
    holding.9 Furthermore, we reject any of plaintiffs’ additional claims that are not rooted in the
    assumption that the SBTA impliedly repealed the election apportionment provisions of
    Compact—and, instead, concern whether the Compact is binding and superior to Michigan
    statutory law—for the reasons provided by this Court in reviewing the validity of 
    2014 PA 282
    in Gillette, which are discussed next in the context of Johnson Matthey’s challenges to 
    2014 PA 282
    .
    9
    Plaintiffs also claim that the Court of Claims erred in determining that plaintiffs’ constitutional
    claims were untimely. For the reasons stated above, we need not address this issue.
    Nevertheless, we note that the Court of Claims correctly held that plaintiffs’
    constitutional challenges were untimely. Pursuant to MCL 205.27a(7), a taxpayer claiming a
    refund on the basis that a Michigan tax statute is invalid under, or is preempted by, a
    constitutional provision or federal law must claim a refund within 90 days of the date set for
    filing a return. See also American States Ins Co v Dep’t of Treasury, 
    220 Mich. App. 586
    , 589,
    591; 560 NW2d 644 (1996). Plaintiffs are seeking refunds premised in part on claims that an
    implied repeal of the Compact election provision would violate various constitutional provisions.
    As such, they are claiming refunds based on arguments that a tax statute is preempted by
    constitutional provisions. Accordingly, under MCL 205.27a, they were required to file those
    claims within 90 days after the date set for filing a return.
    The Court of Claims found that plaintiffs did not assert their constitutional claims within
    the 90-day period, and plaintiffs fail to dispute that finding. Additionally, some plaintiffs do not
    even address the Court of Claims’ ruling that the constitutional claims were untimely. To the
    extent that these plaintiffs fail to address the basis of the Court of Claims’ decision, we deem this
    argument abandoned. Derderian v Genesys Health Care Sys, 
    263 Mich. App. 364
    , 381; 689
    NW2d 145 (2004).

    VI. JOHNSON MATTHEY’S CHALLENGES TO 
    2014 PA 282
    In Docket No. 327251, Johnson Matthey challenges the validity and constitutionality of
    
    2014 PA 282
    (hereinafter referred to as “PA 282”), which the Legislature enacted to
    retroactively withdraw Michigan from the Compact. We reject Johnson Matthey’s claims.
    Johnson Matthey’s numerous state and federal constitutional challenges are identical in
    all relevant respects to the arguments raised by some of the plaintiffs in Gillette. In that case, we
    concluded that the Compact was not a binding contract on this state but was merely an advisory
    agreement, such that PA 282’s removal of Michigan from membership in the Compact was not
    prohibited. Gillette, ___ Mich App at ___; slip op at 18-19, 21-22. Further, “the Compact
    contained no features of a binding interstate compact and, therefore, was not a compact
    enforceable under the Contract Clause.” Id. at ___; slip op at 20. Accordingly, the Compact was
    not superior to statutory law, and it was “subject to Michigan law concerning the interpretation
    of statutes.” Id. at ___; slip op at 18-19, 22. See also id. at ___ n 4; slip op at 19 n 4.
    Furthermore, a retroactive repeal of the Compact did not violate the Contract Clauses of either
    the federal or state Constitutions. Id. at ___; slip op at 19, 21.
    We also held that “the retroactive repeal of the Compact did not violate the Due Process
    Clauses of either the state or federal [C]onstitutions or Michigan’s rules regarding retrospective
    legislation. Nor did it violate the terms of the Compact itself.” Id. at ___; slip op at 22.
    Additionally, we held that the enactment of PA 282 “did not violate the separation of powers
    provision of the state Constitution[.]” Id. at ___; slip op at 30. Moreover, “PA 282 does not
    violate the Commerce Clause” of the United States Constitution. Id. at ___; slip op at 32. We
    also concluded that “the enactment of 
    2014 PA 282
    did not violate the Title-Object Clause, the
    Five-Day Rule, or the Distinct-Statement Clause of the Michigan Constitution.” Id. at ___; slip
    op at 34. Likewise, we rejected the plaintiffs’ change-in-purpose challenge. Id. at ___; slip op at
    38.
    In sum, we rejected in Gillette the same arguments that Johnson Matthey raises here.
    Thus, Johnson Matthey’s constitutional challenges to PA 282 are devoid of merit.
    VII. WHETHER THE SBT IS AN INCOME TAX
    Defendant argues on cross-appeal that the Court of Claims erred in concluding that the
    SBT is an income tax for purposes of the Compact election provision, such that the court
    erroneously concluded that the SBTA was subject to, and therefore conflicted with, the
    Compact’s election provision. We disagree.
    As 
    stated supra
    , the Compact’s apportionment election provision previously stated:
    (1) Any taxpayer subject to an income tax whose income is subject to
    apportionment and allocation for tax purposes pursuant to the laws of a party state
    or pursuant to the laws of subdivisions in 2 or more party states may elect to
    apportion and allocate his income in the manner provided by the laws of such
    state or by the laws of such states and subdivisions without reference to this
    compact, or may elect to apportion and allocate in accordance with Article IV . . .
    . [MCL 205.581, Art III(1) (emphasis added).]
    -18-
    The Compact defined an “income tax” as “a tax imposed on or measured by net income
    including any tax imposed on or measured by an amount arrived at by deducting expenses from
    gross income, 1 or more forms of which expenses are not specifically and directly related to
    particular transactions.” MCL 205.581, Art II(4). As such, “[u]nder the Compact’s broad
    definition, a tax is an income tax if the tax measures net income by subtracting expenses from
    gross income, with at least one of the expense deductions not being specifically and directly
    related to a particular transaction.” 
    IBM, 496 Mich. at 663
    (opinion by VIVIANO, J.).
    The SBT fits this definition. The SBT base is calculated by using federal taxable income
    as a starting point and then making various additions and subtractions as required by the act.

    422 Mich. 473
    , 497, 497 n 15; 373 NW2d 730 (1985). See
    also Trinova Corp v Dep’t of Treasury, 
    433 Mich. 141
    , 150; 445 NW2d 428 (1989) (Trinova I),
    aff’d 
    498 U.S. 358
    ; 
    111 S. Ct. 818
    ; 
    112 L. Ed. 2d 884
    (1991); Lear Corp v Dep’t of Treasury, 
    299 Mich. App. 533
    , 537; 831 NW2d 255 (2013) (“The SBTA unambiguously stated that ‘[tax base]
    means business income’ and ‘[business income] means federal taxable income.’ MCL 208.9(1);
    MCL 208.3(3).” [Alterations in original.]). Federal taxable income, for purposes of the SBT,
    consists of gross income minus deductions allowed by the federal tax code. See MCL 208.5(3),
    citing 26 USC 63. See also 26 USC 63(a); Mobil 
    Oil, 422 Mich. at 497
    n 15. In general,
    deductions from gross income permitted by the federal tax code include ordinary and necessary
    expenses that are paid or incurred while running a business. See 26 USC 162(a); Mobil 
    Oil, 422 Mich. at 489
    .
    As the Court of Claims explained, pursuant to MCL 208.9(2) through (6), “[t]he SBT . . .
    expands the income tax base by adding back some, but not all, of the federal expense deductions
    taken to arrive at federal taxable income.” The Court of Claims further explained:
    For example, except for compensation, most ordinary and necessary business
    expenses incurred in the carrying on of a trade or business are deducted from
    gross income to arrive at federal taxable income, but are not added back as part of
    the SBT tax base. The resulting tax is thus in part measured by “an amount
    arrived at by deducting expenses from gross income” for purposes of defining
    income tax under the Compact. That some expenses such as compensation are
    also added back to the SBT tax base before the tax is calculated does not alter the
    conclusion that the SBT is “imposed on or measured by an amount arrived at by
    deducting expenses from gross income, 1 or more forms of which expenses are
    not specifically and directly related to particular transactions.” Under the plain
    language of the Compact, it is therefore an income tax for Compact purposes.
    [Citations omitted.]
    See also Trinova 
    I, 433 Mich. at 150-151
    (explaining some of the adjustments to “business
    income,” i.e., federal taxable income, which must be made when calculating the SBT base); 
    id. at 149
    n 6 (noting that the SBTA prescribed “various exclusions, exemptions, and industry-specific
    adjustments”).
    -19-
    As the Court of Claims reasoned, some ordinary business expenses, such as insurance
    premiums, rent,10 and research and development costs, which are deducted when calculating
    federal taxable income,11 are not added back when determining the SBT base. See MCL 208.9
    (prescribing the adjustments to federal taxable income that are required in calculating the SBT
    base). Consistent with the Compact’s definition, these expenses are not specifically and directly
    related to particular transactions. See MCL 205.581, Art II(4).
    Therefore, because the SBT is calculated by beginning with federal taxable income,
    which consists of gross income minus federally allowed deductions, and because some
    deductions allowed under the federal tax code are not added back to the SBT base, it follows that
    the SBT is measured by an amount arrived at through the deduction of expenses from gross
    income. Thus, the Court of Claims properly determined that the SBTA qualifies as an income
    tax as defined by the Compact because it “tax[ed] a variation of net income[.]” 
    IBM, 496 Mich. at 667
    (opinion by VIVIANO, J.).
    As defendant emphasizes on appeal, we recognize that a provision of the SBTA stated
    that “[t]he tax levied under this section and imposed is upon the privilege of doing business and
    not upon income.” MCL 208.31(3). However, a similar provision of the MBTA provided that
    “[t]he [modified gross receipts tax (“MGRT”)] levied and imposed under this section is upon the
    privilege of doing business and not upon income or property,” MCL 208.1203(2), and this
    provision did not prevent the Michigan Supreme Court from unanimously concluding in IBM
    that the MGRT was an “income tax” under the broad definition of that term in the Compact, see
    
    IBM, 496 Mich. at 665-667
    (opinion by VIVIANO, J.); 
    id. at 664
    (“Although this statement
    indicates that the MGRT is not a tax upon income under the [M]BTA, we must still determine
    whether the MGRT fits under the broad definition of ‘income tax’ under the Compact.”); 
    id. at 668
    (ZAHRA, J., concurring); 
    id. at 672
    n 3 (MCCORMACK, J., dissenting).
    As the lead opinion in IBM explained, the Court was not required to “put a definitive
    label on the MGRT, a task with which commentators have struggled.” 
    Id. at 663
    n 70 (opinion
    by VIVIANO, J.). Commentators had characterized the MGRT as many types of taxes other than
    an income tax, but the lead opinion in IBM emphasized that its task was merely to determine
    whether the MGRT constituted an “income tax” under the Compact’s definition. Id.; see also 
    id. at 667
    n 85 (“Our holding is limited to the determination that the MGRT is included within the
    Compact definition of ‘income tax.’ . . . [W]e do not need to reach the issue whether the MGRT,
    generally, is an income tax.”).
    Likewise, here, the labels that have been used to describe the SBT in various contexts are
    not dispositive of whether the SBT qualifies as an income tax under the broad Compact
    10
    Although most rental expenses are not added back to the SBT base, MCL 208.9(4)(h) required
    a federal deduction for rent attributable to certain “lease back” transactions to be added back to
    the SBT base.
    11
    See 26 USC 162(a) (allowing federal deductions for ordinary and necessary expenses paid or
    incurred in carrying on a trade or business).
    -20-
    definition of that term. Although both the United States Supreme Court and the Michigan
    Supreme Court have characterized the SBT as a value-added tax that measures business activity
    rather than an income tax, see Trinova 
    II, 498 U.S. at 367
    ; Trinova 
    I, 433 Mich. at 149
    , those
    characterizations were not made in the context of the Compact definition of an income tax.
    Similarly, even though this Court treated the SBT as a value-added tax rather than an income tax
    in determining the application of a federal statute barring state taxes imposed on or measured by
    net income derived from interstate commerce, when the only activity in the state involved
    solicitation of orders, see Gillette Co v Dep’t of Treasury, 
    198 Mich. App. 303
    , 307-311; 497
    NW2d 595 (1993), that analysis was not conducted under the Compact definition of an income
    tax. The issue here is limited to the application of the Compact definition; no definitive
    characterization of the SBT is required, just as no definitive characterization of the MGRT was
    required in IBM in order to conclude that it was an income tax under the Compact. See 
    IBM, 496 Mich. at 663
    n 70 (opinion by VIVIANO, J.).
    VIII. WHETHER PLAINTIFFS’ CLAIMS ARE BARRED BY THE RETROACTIVE
    REPEAL OF THE COMPACT BY 
    2014 PA 282
    Lastly, defendant argues on cross-appeal that the explicit repeal of the Compact by PA
    282 extends to tax years 2005, 2006, and 2007, and taxpayers subject to the SBTA during those
    years. In particular, defendant contends that the language of PA 282 stating that the Compact “is
    repealed retroactively and effective beginning January 1, 2008,” means that no taxpayer may
    attempt to elect the Compact apportionment method following that date. We disagree.
    Defendant’s contention is contravened by the language of the enacting section of PA 282:
    Enacting section 1. 
    1969 PA 343
    , MCL 205.581 to 205.589, is repealed
    retroactively and effective beginning January 1, 2008. It is the intent of the
    legislature that the repeal of 
    1969 PA 343
    , MCL 205.581 to 205.589, is to express
    the original intent of the legislature regarding the application of section 301 of the
    Michigan business tax act, 
    2007 PA 36
    , MCL 208.1301, and the intended effect
    of that section to eliminate the election provision included within section 1 of
    
    1969 PA 343
    , MCL 205.581, and that the 2011 amendatory act that amended
    section 1 of 
    1969 PA 343
    , MCL 205.581, was to further express the original
    intent of the legislature regarding the application of section 301 of the Michigan
    business tax act, 
    2007 PA 36
    , MCL 208.1301, and to clarify that the election
    provision included within section 1 of 
    1969 PA 343
    , MCL 205.581, is not
    available under the income tax act of 1967, 
    1967 PA 281
    , MCL 206.1 to 206.713.
    This language plainly indicates that the Compact was expressly repealed beginning January 1,
    2008. The SBTA was no longer in effect on January 1, 2008, as it was repealed effective
    December 31, 2007. See 
    2006 PA 325
    . Moreover, the enacting section of PA 282 indicates that
    the Legislature’s explicit repeal of the Compact was intended to effectuate the Legislature’s
    original intent concerning the application of MCL 208.1301, a section of the MBTA, and the
    intended effect of that section to eliminate the apportionment election provision of the Compact.
    The enacting section of PA 282 also explains that 
    2011 PA 40
    was intended to further express
    the Legislature’s original intent with regard to the application of MCL 208.1301 and to clarify
    that the Compact apportionment election provision was not available under the income tax act of
    -21-
    1967. There is no language in the enacting section that suggests a legislative intent to repeal the
    Compact with respect to tax years affected by the SBTA or with respect to SBT taxpayers. See
    Sun Valley 
    Foods, 460 Mich. at 236
    (“If the language of the statute is unambiguous, the
    Legislature must have intended the meaning clearly expressed, and the statute must be enforced
    as written.”).
    Moreover, the lead and concurring opinions in IBM also support the conclusion that PA
    282’s explicit repeal of the Compact effective January 1, 2008 did not extend to tax years before
    2008. In IBM, our Supreme Court analyzed 
    2011 PA 40
    , which contained language similar to
    the enacting section of PA 282. 
    2011 PA 40
    stated that “beginning January 1, 2011[,]” a
    taxpayer subject to the MBTA or the income tax act of 1967 could not elect to use the Compact
    apportionment formula. The lead and concurring opinions concluded that the Compact election
    provision was in effect for the 2008 tax year at issue in IBM, implicitly finding that the
    “beginning January 1, 2011” language in 
    2011 PA 40
    denotes tax years beginning in 2011. See
    
    IBM, 496 Mich. at 659
    (opinion by VIVIANO, J.); 
    id. at 668
    -670 (ZAHRA, J., concurring). See also
    Gillette, ___ Mich App at ___; slip op at 17 (“In IBM, the Supreme Court held that through 
    2011 PA 40
    the Legislature created a window (from January 1, 2008 until January 1, 2011) wherein
    relevant taxpayers could still utilize the apportionment option available under Article IV of the
    Compact.”). Likewise, the language in PA 282 stating that the Compact was repealed “effective
    beginning January 1, 2008,” is properly understood as indicating that the express repeal of the
    Compact applies to tax years beginning on January 1, 2008.
    Thus, the express repeal of the Compact by PA 282 does not apply to the SBTA.
    IX. CONCLUSION
    We agree with plaintiffs that the trial court erred in concluding that the SBTA impliedly
    repealed the Compact election provision. However, the rest of plaintiffs’ claims on appeal, as
    well as defendant’s alternative grounds for affirmance, lack merit.
    Reversed and remanded for further proceedings consistent with this opinion. We do not
    retain jurisdiction. No costs, an issue of public importance being involved. MCR 7.219(A).
