  • ConAgra Foods RDM, Inc. v. Comptroller of the Treasury, No. 1940, September Term,
    2015. Opinion by Woodward, J.
    TAXATION – INCOME TAX – CORPORATION INCOME TAX – TAXATION OF
    NON-DOMICILIARY CORPORATION – CONSTITUTIONAL REQUIREMENTS
    For a state to tax a non-domiciliary corporation, such taxation must withstand constitutional
    scrutiny under both the Due Process and Commerce Clauses of the United States
    Constitution. Although these clauses have different purposes and requirements, they have
    significant parallels. The Due Process Clause requires that (1) there be a minimal
    connection between the interstate activities of the non-domiciliary corporation and the
    taxing state, and (2) there be a rational relationship between the income attributed to the
    taxing state and the intrastate values of the enterprise being taxed. The Commerce Clause
    requires that the tax in question (1) apply to an activity with a substantial nexus with the
    taxing state, (2) be fairly apportioned, (3) not discriminate against interstate commerce,
    and (4) be fairly related to the services the taxing state provides.
    TAXATION – INCOME TAX – CORPORATION INCOME TAX – TAXATION OF
    NON-DOMICILIARY CORPORATION – CONSTITUTIONAL REQUIREMENTS
    – LACK OF ECONOMIC SUBSTANCE AS A SEPARATE ENTITY
    In Gore Enter. Holdings, Inc. v. Comptroller, 
    437 Md. 492
    (2014), the Court of Appeals
    held that the constitutional requirements for taxation of out-of-state wholly owned
    subsidiary corporations are satisfied where the subsidiaries “ha[ve] no real economic
    substance as separate business entities” from their parent corporations that do business in
    Maryland. (quoting Comptroller v. SYL, Inc., 
    375 Md. 78
    , 106, cert. denied, 
    540 U.S. 984
    and cert. denied, 
    540 U.S. 1090
    (2003)). After reviewing the Court of Appeals’ opinions
    in Gore and SYL, the Court articulated the four factors that courts should look to in
    determining whether a foreign wholly owned subsidiary lacks economic substance as a
    business entity separate and apart from its parent corporation that does business in
    Maryland. First, a court should consider how dependent the subsidiary is on its parent
    company for income. Second, a court should consider whether there is a circular flow of
    money from the parent company to the subsidiary and then back to the parent. Third, a
    court should consider how much the subsidiary relies on the parent for its core functions
    and services. Fourth, a court should consider whether the subsidiary engages in substantive
    activity that is in any meaningful way separate from the parent.
    Applying these factors to the instant case, which involved a foreign wholly owned
    subsidiary, Brands, and Brands’s parent corporation, ConAgra, the Court held that there
    was substantial evidence to support the Tax Court’s findings of (1) Brands’s dependence
    on ConAgra and its other subsidiaries for the “vast majority” of its income, (2) the circular
    flow of money from ConAgra and its subsidiaries to Brands and back to ConAgra, (3)
    Brands’s reliance on ConAgra for its core functions, and (4) Brands’s lack of any
    meaningful substantive activity separate from ConAgra.
    The Court rejected Brands’s argument that third-party income received by Brands gave it
    economic substance as a separate entity, noting that Brands received the vast majority of
    its income from ConAgra and the latter’s subsidiaries. The Court also rejected Brands’s
    argument that, because Brands did not pay dividends or make loans to ConAgra, there was
    no circular flow of money between them, emphasizing that the cash management system
    utilized by ConAgra and its subsidiaries achieved the same functional result. The Court
    additionally rejected Brands’s argument that the Tax Court, in affirming the Comptroller’s
    assessment against it, should have given more weight to the non-tax business reasons for
    the establishment of Brands. The Court noted that the motivation behind creating Brands
    was not dispositive.
    TAXATION – INCOME TAX – CORPORATION INCOME TAX –
    APPORTIONMENT OF MARYLAND MODIFIED INCOME – 3-FACTOR
    FORMULA – MODIFICATION BY COMPTROLLER – USE OF BLENDED
    APPORTIONMENT FORMULA
    The Tax General Article provides that, where a corporation does business both within and
    outside of the state, the corporation shall allocate to Maryland the part of the corporation’s
    Maryland modified income that is derived from or reasonably attributable to the part of its
    trade or business carried on in Maryland. TG § 10-402(a)(2) (now §10-402(b)(2)).
    Although the Tax General Article lays out a 3-factor apportionment formula, the Article
    also empowers the Comptroller to modify elements of the formula “[t]o reflect clearly the
    income allocable to Maryland[.]” TG § 10-402(e). The Court held that, because utilizing
    the traditional 3-factor formula would have resulted in an apportionment factor of zero for
    Brands’s payroll, property, and sales in Maryland, the Comptroller had adequately
    demonstrated the need to alter the 3-factor formula. The Court further held that the
    Comptroller did not err or abuse its discretion in utilizing a “blended apportionment factor”
    that was derived from the apportionment factors used by ConAgra and its subsidiaries.
    TAXATION – INCOME TAX – INTEREST – WAIVER OF INTEREST AND
    PENALTIES BY THE TAX COURT
    The authority to abate interest owed on unpaid taxes vests both in the tax collector and the
    Tax Court. When reviewing the Comptroller’s decision not to abate interest, the Tax Court
    must consider whether the taxpayer has demonstrated with affirmative evidence that
    reasonable cause exists for abatement or that the tax Comptroller’s decision was an obvious
    error. Noting that “reasonable cause” is not defined in the Tax General Article, and that
    courts give great weight to the legal conclusions of administrative agencies regarding the
    statutes that they administer, the Court held that the Tax Court may properly find that
    reasonable cause exists for abatement of interest where there is uncertainty in the state of
    the caselaw when applied to the circumstances of a particular taxpayer.

    Suzanne C. Johnson, Clerk
    Appellant, ConAgra Foods RDM, Inc., formerly known as ConAgra Brands, Inc.
    (“Brands”),1 is an intellectual property holding company and a direct and indirect wholly
    owned subsidiary of ConAgra Foods, Inc., formerly known as ConAgra, Inc. (“ConAgra”).
    Brands was incorporated in 1996 in Nebraska and has a principal office in Omaha,
    Nebraska. During the time period of 1996 through 2003, ConAgra conducted business
    operations in Maryland and filed corporation income tax returns in Maryland. For the same
    time period, Brands did not file any Maryland corporation income tax returns. Because
    Brands received royalties from ConAgra,2 appellee, the Comptroller of the Treasury
    (“Comptroller”), on August 30, 2007, assessed Brands $2,768,588 in back taxes, interest,
    and penalties for the tax years of 1996 through 2003. Brands appealed this assessment,
    and the Comptroller affirmed by issuing a Notice of Final Determination on January 23,
    2009.
    On February 23, 2009, Brands appealed to the Tax Court. After a hearing, the Tax
    Court ruled, in a Memorandum of Grounds for Decision dated February 24, 2015, that
    Brands lacked economic substance as a business entity separate from ConAgra and thus
    allowed the Comptroller to impose the tax assessment. The Tax Court, however, abated
    the interest accrued from the date of the appeal to that court to the date of its decision, and
    all penalties. Brands and the Comptroller filed petitions for judicial review in the Circuit
    1
    Throughout this opinion, we will refer to ConAgra Foods RDM, Inc. as Brands. It
    is undisputed that ConAgra Brands, Inc., a Nebraska corporation, and ConAgra Foods
    RDM, Inc., a Delaware corporation, merged in 2007.
    2
    Brands also received royalties from other wholly owned subsidiaries of ConAgra
    who filed corporation income tax returns in Maryland.
    Court for Anne Arundel County, which resulted in the court affirming the Tax Court’s
    decision, except for the latter’s abatement of interest accruing from March 24, 2014 to
    February 24, 2015. Brands then filed this timely appeal.
    Brands presents eight questions for our review, which we have rephrased and
    condensed into three:3
    3
    Brands’s questions, as set forth in its brief, are as follows:
    1. Did the Tax Court commit error when it confirmed the Comptroller’s
    assessment against Brands even though Brands had economic substance
    as a separate business entity?
    2. Did the Tax Court commit error when it failed to find that the
    Comptroller’s assessment against Brands violated the Due Process
    Clause of the United States Constitution because Brands did not
    purposefully avail itself of the Maryland marketplace and had no other
    contacts with the state?
    3. Did the Tax Court commit error when it failed to confirm that the
    Comptroller’s assessment against Brands violated the Commerce Clause
    of the United States Constitution because Brands lacked a substantial
    nexus with the state?
    4. Did the Tax Court commit error when it confirmed the Comptroller’s
    assessment against Brands even though the Comptroller failed to follow
    the Sec. 10-402(c) standard statutory apportionment formula?
    5. Did the Tax Court commit error when it confirmed the Comptroller’s
    assessment against Brands even though the Comptroller, in adopting an
    apportionment methodology[,] failed to establish that the statutory
    apportionment formula did not fairly represent the extent of Brands’[s]
    business activities in the state?
    6. Did the Tax Court commit error when, in violation of the Due Process
    and Commerce Clauses of the United States Constitution, it confirmed
    the Comptroller’s adoption of an alternative apportionment formula that
    failed to reasonably reflect Brands’[s] business activities in the state?
    7. Did the Tax Court commit error by confirming the Comptroller’s
    assessment against Brands in finding that Brands lacked economic
    substance and, as a result, essentially did not, for tax purposes, exist as a
    separate legal entity?
    8. Did the Tax Court abuse its discretion when it partially waived interest
    on the tax assessment against Brands?
    2
    1.     Was there substantial evidence to support the Tax Court’s
    ruling that Brands lacked economic substance as a business
    entity separate from ConAgra and thus had the
    constitutionally required nexus and minimum contacts with
    Maryland to subject Brands to income taxation by Maryland
    for the royalties received by Brands from ConAgra and its
    subsidiaries arising out of the latters’ business activities in
    Maryland?
    2.     Was there substantial evidence to support the Tax Court’s
    ruling that the Comptroller had the statutory authority to use
    a blended apportionment formula to determine Brands’s
    Maryland income and that the blended apportionment
    formula clearly reflected Brands’s income allocable to
    Maryland?
    3.     Did the Tax Court properly interpret the tax statute when it
    waived interest on the income tax due from Brands that
    accrued from the date of the filing of its appeal to the Tax
    Court (February 23, 2009) to the date of the issuance of that
    court’s decision (February 24, 2015)?
    For the reasons set forth below, we uphold the decision of the Tax Court in all respects and
    thus affirm in part and reverse in part the judgment of the circuit court.
    BACKGROUND
    ConAgra is a conglomerate known for its agricultural products and products in the
    processed food industry including, but not limited to, Hunts, Orville Redenbacher,
    Butterball Turkey, and ACT II. In the late 1990s, ConAgra had multiple wholly owned
    subsidiaries (also known as independent operating companies), including Swift-Eckrich,
    Inc., Hunt-Wesson, Inc., and Beatrice Cheese, Inc. The multitude of ConAgra’s wholly
    owned subsidiaries began to present management problems for ConAgra, and in 1996,
    ConAgra began a program focused on corporate centralization.
    One such centralization initiative occurred in April 1996 when ConAgra decided to
    3
    centralize management of the intellectual property owned by it and its subsidiaries. To
    effectuate this goal, ConAgra incorporated Brands in Nebraska. Brands issued 2,207
    shares of common stock, distributing 1,000 shares to ConAgra, 594 shares to Swift-
    Eckrich, Inc, 560 shares to Hunt-Wesson, Inc., and 53 shares to Beatrice Cheese, Inc. In
    exchange, Brands acquired forty-six initial trademark groups and subsequently acquired
    numerous other trademark groups from these entities. Brands then entered into license
    agreements for the trademark groups with ConAgra and the three subsidiaries, under which
    ConAgra and these subsidiaries paid Brands royalties.4
    From 1996 to 2003, Brands did not file Maryland tax returns, but ConAgra and some
    of its subsidiaries did file Maryland tax returns. After an audit, the Comptroller sent Brands
    a “Notice and Demand to File Maryland Corporation Income Tax Returns” in 2007. When
    Brands did not respond to the Comptroller’s notice and demand, the Comptroller issued a
    “Notice of Assessment” for the tax years of 1996 to 2003 for a total of $2,768,588 in back
    taxes, interest, and penalties as of August 30, 2007.          Upon Brands’s request, an
    administrative appeal was held on December 4, 2007, concerning the Comptroller’s
    assessment.     On January 23, 2009, the Comptroller issued a “Notice of Final
    Determination[,]” concluding that Brands then owed $3,053,222 in back taxes, interest,
    and penalties. Brands filed a timely Petition of Appeal to the Tax Court on February 23,
    2009.
    4
    Although not clear from the record, it appears that during the tax years in question,
    royalties were paid to Brands by ConAgra and either the three subsidiaries or their
    respective successors.
    4
    After a two-day hearing concluding on October 7, 2010, the Tax Court issued its
    opinion upholding the Comptroller’s assessment on February 24, 2015. The Tax Court
    stated that the “initial inquiry [was] to determine whether [Brands] had real economic
    substance as a business separate from ConAgra.” Citing to Comptroller v. SYL, Inc., 
    375 Md. 78
    , cert. denied, 
    540 U.S. 984
    and cert. denied, 
    540 U.S. 1090
    (2003) and Gore Enter.
    Holdings, Inc. v. Comptroller, 
    437 Md. 492
    (2014), the Tax Court observed that, under the
    economic substance doctrine set forth in those cases, an out-of-state subsidiary “must have
    economic substance as a separate entity from its parent to avoid nexus and taxation.” After
    a review of the evidence before it, the court concluded that Brands lacked any economic
    substance separate from ConAgra. Because a portion of Brands’s income was produced
    from the business of ConAgra and its subsidiaries in Maryland, the court held that there
    was sufficient nexus to support the income taxation of Brands.
    The Tax Court then considered whether the Comptroller applied an appropriate
    apportionment formula in calculating the income tax that Brands owed to Maryland. The
    Tax Court determined that the Comptroller’s blended apportionment formula was
    permissible, because “the Comptroller effectively utilized ConAgra’s own apportionment
    figures in constructing the blended apportionment factor used in this case.”5 Finally, the
    Tax Court abated the interest accruing after the date of filing the appeal to the Tax Court
    (February 23, 2009) to the date of the Tax Court’s decision (February 24, 2015), and all
    5
    The record revealed that the apportionment factor was calculated using the
    apportionment factors of ConAgra and its subsidiaries that filed corporation income tax
    returns in Maryland.
    5
    penalties.6
    On March 17, 2015, Brands filed a petition for judicial review in the circuit court
    challenging the Tax Court’s ruling that it was subject to Maryland tax, as well as the
    Comptroller’s apportionment formula. The Comptroller filed a cross-petition for judicial
    review challenging the Tax Court’s decision to abate all interest accruing from the date of
    filing the appeal with the Tax Court to the issuance of that court’s decision. After a hearing
    on September 21, 2015, the circuit court issued an opinion and order on October 30, 2015,
    affirming the Tax Court in all respects, except for the latter’s abatement of interest accruing
    from March 24, 2014 to February 24, 2015.7
    Brands filed this timely appeal. Additional facts will be set forth below as they
    become necessary to the resolution of the questions presented in this appeal.
    STANDARD OF REVIEW
    The Tax Court is an adjudicatory administrative agency; “our review looks through
    the circuit court’s . . . decision[ ] . . . and evaluates the decision of the agency.” Gore, 437
    6
    The Tax Court also concluded that the assessment, which was issued in 2007, was
    not barred by the statute of limitations, because the “three-year statute of limitations for
    assessments does not apply when a taxpayer does not file a required return,” and Brands
    did not file a return for any of the tax years at issue. That ruling is not at issue before this
    Court.
    7
    The circuit court viewed the instant case “to be substantially similar to the factual
    situation in Gore, and as such, the [c]ourt finds that the interest in the instant case should
    be treated in the same way as it was treated in Gore.” In Gore, the Court of Appeals did
    not disturb the Comptroller’s assessment of interest. 
    Gore, 437 Md. at 503
    . The circuit
    court held that the Tax Court abused its discretion by abating the interest “collected after
    the date of issuance of the Gore decision on March 24, 
    2014.” 6 Md. at 503
    (some alterations in original) (internal quotation marks omitted). The Court of
    Appeals has further explained our review of a decision of the Tax Court as follows:
    An administrative agency’s findings of fact must meet the
    substantial evidence standard. Frey [v. Comptroller,] 422 Md. [111,]
    [ ] 137, 29 A.3d [475,] [ ] 490 (citations omitted). Thus, we
    determine “‘whether a reasoning mind reasonably could have
    reached the factual conclusion the agency reached.’” 
    Frey, 422 Md. at 137
    , 29 A.3d at 490 (quoting State Ins. Comm’r v. Nat’l Bureau
    of Cas. Underwriters, 
    248 Md. 292
    , 309, 
    236 A.2d 282
    , 292 (1967)).
    It is not our place to “make an independent original estimate of our
    decision on the evidence.... [or determine for ourselves], as a matter
    of first instance, the weight to be accorded to the evidence before the
    agency.” In Ramsay Scarlett & Co., Inc. v. Comptroller of the
    Treasury, 
    302 Md. 825
    , 838, 
    490 A.2d 1296
    , 1303 (1985) (citations
    omitted), we cautioned:
    [T]hat a reviewing court may not substitute its judgment
    for the expertise of the agency; that we must review the
    agency’s decision in the light most favorable to it; that
    the agency’s decision is prima facie correct and presumed
    valid; and that it is the agency’s province to resolve
    conflicting evidence and where inconsistent inferences
    can be drawn from the same evidence it is for the agency
    to draw the inferences.
    
    Ramsay, 302 Md. at 834
    –35, 490 A.2d at 1301 (citations omitted).
    “[T]he interpretation of the tax law can be a mixed question of
    fact and law, the resolution of which requires agency expertise.”
    Comptroller of the Treasury v. Citicorp Int’l Commc’ns, Inc., 
    389 Md. 156
    , 164, 
    884 A.2d 112
    , 116–17 (2005) (citing NCR Corp. v.
    Comptroller, 
    313 Md. 118
    , 133–34, 
    544 A.2d 764
    , 771 (1988)). In
    reviewing mixed questions of law and fact, “we apply ‘the
    substantial evidence test, that is, the same standard of review [we]
    would apply to an agency factual finding.’” Comptroller of the
    Treasury v. Science Applications Intern. Corp., 
    405 Md. 185
    , 193,
    
    950 A.2d 766
    , 770 (2008) (quoting Longshore v. State, 
    399 Md. 486
    ,
    522 n. 8, 
    924 A.2d 1129
    , 1149 n. 8 (2007)).
    7
    The legal conclusions of an administrative agency that are
    “premised upon an interpretation of the statutes that the agency
    administers” are afforded “great weight.” 
    Frey, 422 Md. at 138
    , 29
    A.3d at 490 (citations omitted). Agency decisions premised upon
    case law, however, are not entitled to deference. 
    Frey, 422 Md. at 138
    , 29 A.3d at 490 (“When an agency’s decision is necessarily
    premised upon the ‘application and analysis of caselaw,’ that
    decision rests upon ‘a purely legal issue uniquely within the ken of
    a reviewing court.’” (quoting [People’s Counsel for Baltimore Cty.
    v.] Loyola College [in Md.], 406 Md. [54,] [ ] 67–68, 956 A.2d [166,]
    [ ] 174 [2008])).
    
    Id. at 504-05
    (some alterations in original).
    DISCUSSION
    I.    Taxation and the United States Constitution
    For a state to tax a non-domiciliary company, like Brands, such taxation must
    withstand constitutional scrutiny under the Due Process and Commerce Clauses of the
    United States Constitution.     
    Gore, 437 Md. at 506-07
    .        The satisfaction of these
    constitutional restrictions on government action have different purposes and requirements,
    but these clauses also have “significant parallels.” South Dakota v. Wayfair, Inc., 138 S.
    Ct. 2080, 2093 (2018).
    The Due Process Clause imposes restrictions on the government to act in a fair
    manner and provide “fair warning.” 
    Gore, 437 Md. at 507
    . Under the Due Process Clause,
    there are “two requirements: [1] a ‘minimal connection’ between the interstate activities
    and the taxing State, and [2] a rational relationship between the income attributed to the
    State and the intrastate values of the enterprise.” Mobil Oil Corp. v. Comm’r of Taxes of
    Vermont, 
    445 U.S. 425
    , 436-37 (1980).
    8
    The Commerce Clause, on the other hand,
    was designed to prevent States from engaging in economic
    discrimination so they would not divide into isolated, separable
    units. See Philadelphia v. New Jersey, 
    437 U.S. 617
    , 623, 
    98 S. Ct. 2531
    , 
    57 L. Ed. 2d 475
    (1978). But it is “not the purpose of the
    [C]ommerce [C]lause to relieve those engaged in interstate
    commerce from their just share of state tax burden.” Complete Auto
    [Transit, Inc. v. Brady, 
    430 U.S. 274
    , 288 (1977)] (internal quotation
    marks omitted).
    
    Wayfair, 138 S. Ct. at 2093-94
    (alterations in original). The Commerce Clause requires
    that a tax “(1) appl[y] to an activity with a substantial nexus with the taxing State, (2) [be]
    fairly apportioned, (3) [ ] not discriminate against interstate commerce, and (4) [be] fairly
    related to the services the State provides.” 
    Id. at 2091.
    The first prong of the Commerce
    Clause “test simply asks whether the tax applies to an activity with a substantial nexus with
    the taxing State. [S]uch a nexus is established when the taxpayer [or collector] avails itself
    of the substantial privilege of carrying on business in that jurisdiction.” 
    Id. at 2099
    (alterations in original) (internal citation and quotation marks omitted). In holding that
    such nexus can be satisfied through “economic and virtual contacts,” the Court overturned
    its previous precedent of requiring that a company have physical presence within the State
    imposing taxation, and in so doing, moved the nexus requirement in the Commerce Clause
    and the Due Process Clause requirement of minimal contacts into closer alignment. See
    
    id. at 2092-93
    (“This nexus requirement is closely related to the due process requirement
    that there be some definite link, some minimum connection, between a state and the person,
    property or transaction it seeks to tax.” (internal citation and quotation marks omitted)).
    9
    II.   Lack of Economic Substance as a Separate Entity
    In the instant case, Brands is an out-of-state direct and indirect wholly owned
    subsidiary of ConAgra. During the tax years in question, Brands received royalties under
    the trademark license agreements from ConAgra and its subsidiaries, a portion of which
    was derived from the business activities of ConAgra and its subsidiaries in Maryland. In
    SYL and Gore, the Court of Appeals held that the constitutional requirements for state
    taxation of out-of-state wholly owned subsidiary corporations are satisfied where the
    subsidiaries “‘had no real economic substance as separate business entities.’” 
    Gore, 437 Md. at 513-14
    (quoting 
    SYL, 375 Md. at 106
    ) (bold emphasis in Gore). In other words, the
    Due Process Clause requirement of “minimum contacts” and the Commerce Clause
    requirement of “nexus” are satisfied for such subsidiaries “‘based upon their parent
    corporations’ Maryland business[.]’” 
    Gore, 437 Md. at 514
    (alteration in original) (quoting
    
    SYL, 375 Md. at 109
    ). Therefore, the central issue raised in the instant case is whether
    Brands had real economic substance as a business entity separate from ConAgra. To
    resolve this issue, we must begin with a close examination of SYL and Gore.
    A. SYL
    In SYL, the Court of Appeals consolidated two cases in which the Comptroller
    assessed Maryland taxes against foreign intellectual property holding companies that were
    wholly owned subsidiaries of parent companies doing business in 
    Maryland. 375 Md. at 80-81
    , 92.
    The first case involved the clothing company Syms, Inc. (“Syms”). 
    Id. at 81.
    Syms
    created a wholly owned subsidiary, SYL, Inc. (“SYL”), and incorporated this subsidiary in
    10
    Delaware. 
    Id. Syms then
    transferred all of its intellectual property to SYL, and “SYL
    granted to Syms a license to manufacture, use and sell the products covered by the trade
    names and trademarks in [Syms]’s business[.]” 
    Id. SYL received
    royalties pursuant to its
    license agreement with Syms, and SYL, in turn, would issue dividends to Syms — the
    owner of all of SYL’s stock. 
    Id. at 81,
    86. Although Syms filed Maryland corporation
    income tax returns, SYL did not, and in 1996, the Comptroller issued an assessment against
    SYL “for the years 1986 through 1993 [in the] amount of $637,362 in corporate income
    taxes, including interest and penalties.” 
    Id. at 81.
    The companion case involved Crown Cork & Seal Company (Delaware) (“Crown
    Delaware”). 
    Id. at 92.
    Crown Delaware was a wholly owned subsidiary of Crown Cork &
    Seal Company, Inc. (“Crown Parent”), which was “a corporation engaged in the
    manufacturing and sale of metal cans, crowns, and closures for bottles, can-filling
    machines, and plastic bottles and containers, world-wide, including in the State of
    Maryland.” 
    Id. (internal quotation
    marks omitted). Crown Delaware was a Delaware
    corporation created by Crown Parent to manage its intellectual property, and Crown
    Delaware acquired “thirteen domestic patents and sixteen trademarks” from Crown Parent.
    
    Id. “Crown Delaware
    then granted to Crown Parent an exclusive license . . . [and] Crown
    Parent agreed to pay Crown Delaware a royalty based on Crown Parent’s sales.” 
    Id. at 94.
    Then, Crown Delaware would provide Crown Parent with loans, sometimes the same day
    as it received royalties from Crown Parent. 
    Id. at 96.
    Like SYL and Syms, Crown
    Delaware did not file corporation income tax returns in Maryland, but Crown Parent did.
    11
    
    Id. at 92.
    The Comptroller issued an assessment against Crown Delaware for $1,421,034
    in back taxes including interest and penalties, for the years 1989 through 1993. 
    Id. SYL and
    Crown Delaware took separate appeals to the Tax Court. 
    Id. at 84,
    93. In
    separate decisions, the Tax Court concluded that Maryland did not have the authority to
    tax SYL and Crown Delaware, because both companies were not completely shell
    corporations and neither had a sufficient nexus with Maryland. 
    Id. at 88-90,
    98-99. The
    Comptroller appealed both cases, and the circuit court upheld the Tax Court in separate
    rulings. 
    Id. at 91,
    99. Again, the Comptroller appealed, but before the appeals were heard
    by this Court, the Court of Appeals granted the petitions for a writ of certiorari. 
    Id. On appeal,
    the Court of Appeals examined this Court’s opinion in Comptroller v.
    Armco Exp. Sales Corp., 
    82 Md. App. 429
    , cert. denied, 
    320 Md. 634
    (1990), and cert.
    denied, 
    498 U.S. 1088
    (1991). 
    SYL, 375 Md. at 103-05
    . In that case, this Court considered
    whether Maryland had the authority to tax three subsidiaries created by Armco, Inc.,
    General Motors, and Thiokol. 
    Id. at 103.
    These subsidiaries were known as “Domestic
    International Sales Corporation[s] or DISC[s,]” and their sole purpose was to buy goods
    from their respective parents and then resell the goods to overseas customers, incurring for
    the parent a federal tax benefit. 
    Id. at 103-04.
    This Court held that Maryland could tax the
    income of the DISCs. 
    Id. at 105.
    We noted that the parent companies conducted business
    in Maryland. 
    Id. at 104.
    We also noted that the DISCs relied completely on their respective
    parent corporations, because each DISC had “no tangible property or employees and
    c[ould] only conduct its activity and do business through branches of its unitary affiliated
    parent.” 
    Id. (internal quotation
    marks omitted).
    12
    The Court of Appeals adopted our Armco reasoning and applied it to SYL and
    Crown Delaware. 
    Id. at 106.
    The Court noted that SYL and Crown Delaware resembled
    the DISC corporations in Armco, “except that SYL and Crown Delaware had a touch of
    ‘window dressing’ designed to create an illusion of substance.” 
    Id. The Court
    continued:
    Neither subsidiary had a full time employee, and the ostensible part
    time “employees” of each subsidiary were in reality officers or
    employees of independent “nexus-service” companies. The annual
    wages paid to these “employees” by the subsidiaries were
    minuscule. The so-called offices in Delaware were little more than
    mail drops. The subsidiary corporations did virtually nothing;
    whatever was done was performed by officers, employees, or
    counsel of the parent corporations. The testimony indicated that,
    with respect to the operations of the parents and the protections
    of the trademarks, nothing changed after the creation of the
    subsidiaries. Although officers of the parent corporations may have
    stated that tax avoidance was not the sole reason for the creation of
    the subsidiaries, the record demonstrates that sheltering income from
    state taxation was the predominant reason for the creation of SYL
    and Crown Delaware.
    
    Id. (Emphasis added).
    Indeed, the undisputed record revealed that SYL was completely dependent on
    Syms for income, and all income was returned to Syms in the form of dividends. 
    Id. at 84,
    86. SYL’s Board of Directors were all officers of Syms, except that one Board member,
    Edward Jones, was an accountant employed by the firm Gunnip and Company — a firm
    SYL hired to provide services, such as a mailing address, and to establish a presence in
    Delaware. 
    Id. at 86-87.
    Daily expenses at SYL were minimal, the record indicating that
    SYL only spent $2,400 a year for services provided by Gunnip and Company, which
    included $1,200 a year for the “salary” of Jones, SYL’s sole employee. 
    Id. at 87.
    No
    expenses were for the protection of any trademarks, and SYL’s license agreement with
    13
    Syms provided Syms with full control over the trademarks and the protection of the marks.
    
    Id. at 87-88.
    As to Crown Delaware, the undisputed record revealed that Crown Parent held the
    exclusive license to Crown Delaware’s intellectual property. 
    Id. at 94.
    Crown Delaware
    and Crown Parent’s circular flow of money was evidenced by Crown Parent paying Crown
    Delaware royalties and Crown Delaware loaning money back to Crown Parent, sometimes
    on the same day. 
    Id. at 96.
    The day to day operations of Crown Delaware were handled
    by Organization Services, Inc. (“OSI”). 
    Id. at 94-95.
    For $100 a month, OSI provided
    office space, a mailing address, and nine part-time employees who were paid a total of
    $843.66 in wages for 1993. 
    Id. at 95-96.
    In short, Crown Delaware’s revenues “averaged
    around thirty-seven million dollars annually” but only spent on average just over two
    thousand dollars annually in expenses — none of which were for legal fees. 
    Id. at 97.
    The
    record was devoid of any indication that Crown Delaware performed any function to
    promote or preserve the intellectual property it had acquired from Crown Parent. 
    Id. at 97-
    98.
    The Court of Appeals concluded that “SYL and Crown Delaware had no real
    economic substance as separate business entities.” 
    Id. at 106.
    Accordingly, the Court held
    “that a portion of SYL’s and Crown Delaware’s income, based upon their parent
    corporations’ Maryland business, is subject to Maryland income tax.” 
    Id. at 109.
    B. Gore
    Gore is the most recent case involving the taxation of a foreign intellectual property
    holding company that is a wholly owned subsidiary of a corporation doing business in
    14
    Maryland. 
    437 Md. 492
    . In Gore, W.L. Gore & Associates, Inc. (“Gore”) was a
    manufacturing company of “fabrics, medical devices, electronics, and industrial products”
    that operated factories in several states, including Maryland. 
    Id. at 499-500.
    In 1983, Gore
    incorporated Gore Enterprise Holdings, Inc. (“GEH”) in Delaware to manage its patents.
    
    Id. at 500.
    Gore assigned to GEH all of its patents and certain other assets in exchange for
    GEH’s entire stock. 
    Id. GEH then
    licensed the patents back to Gore for a royalty fee on
    all products sold by Gore. 
    Id. GEH also
    entered into a licensing agreement with Gore that
    allowed Gore’s attorneys to control the legal defense to patent infringement, licensing
    activities, and patent applications. 
    Id. In addition,
    GEH did not have any employees until
    1995, when it hired one employee to manage the patent portfolio. 
    Id. at 500-01.
    In 1996, Gore incorporated Future Value, Inc. (“FVI”)
    in Delaware to manage Gore’s excess capital. A Gore-employed
    attorney incorporated it, and two members of the Gore Board, along
    with GEH’s Vice President, comprised the FVI Board. Upon FVI’s
    formation, GEH transferred all of its investment securities to FVI, in
    exchange for all of the shares of FVI. GEH then declared a dividend
    to its sole shareholder, Gore, in the form of the FVI stock. This made
    Gore the sole owner of FVI. FVI was founded primarily to perform
    investment management functions, but has also extended Gore a line
    of credit when Gore experienced negative cash flow. As of 2008,
    FVI had three employees that handled, monitored, and recorded the
    various activities performed by FVI.
    
    Id. at 501
    (footnote omitted).
    In 2006, the Comptroller assessed back income taxes, interest, and penalties in the
    amount of $26,436,315 against GEH for the years 1983 through 2003. 
    Id. Concurrently, the
    Comptroller assessed FVI $2,608,895 in back income taxes, interest, and penalties for
    the years 1996 through 2003. 
    Id. The Tax
    Court upheld the Comptroller’s tax assessment,
    15
    ruling that GEH and FVI lacked economic substance separate from Gore, but the circuit
    court reversed. 
    Id. at 501
    -02. The Comptroller appealed to this Court, and we upheld the
    Tax Court’s ruling that GEH and FVI were subject to Maryland tax. 
    Id. at 502.
    GEH and
    FVI petitioned the Court of Appeals for a writ of certiorari, which was granted. 
    Id. The Court
    of Appeals began its analysis by agreeing with the Tax Court that the
    threshold issue on appeal was whether GEH and FVI lacked economic substance as
    business entities separate from Gore. The Court observed that the Tax Court
    marshaled numerous factual findings, supported by substantial
    record evidence. These included the following:
    • There were no outside Directors of GEH or FVI and prior to
    1996 the W.L. Gore family dominated the Officer list.
    • FVI was simply an intentional depository for assets built up
    through royalties paid to the patent company, GEH.
    • In effect, GEH does not create, invent or make anything and
    must rely on W.L. Gore employees to invent the new process or
    product. Thus, an idea generated by a technologist with W.L.
    Gore is prepared by GEH through an application for filing with
    the patent office. In most cases, the employees of W.L. Gore
    review the patent application and determine whether it should be
    pursued.
    • The testimony in the case suggests that GEH relied on W.L.
    Gore for a continuing stream of inventions and discoveries as set
    forth in the materials that make up the patent application.
    • The manufacture or sale of the product by W.L. Gore obligates
    the payment of royalties to GEH under the License Agreement.
    • GEH as licensor to W.L. Gore, Inc., licensee, is dependent on
    the licensee’s activities to obtain consideration for grants of the
    license. Although GEH has separate corporate status, the inter-
    dependence reflected in the third party License Agreements
    16
    suggests that the patent committee of GEH strongly considers the
    interest of W.L. Gore in making its decisions.
    • One witness for GEH who described herself as a Patent
    Administrator confirmed that W.L. Gore employees would
    prepare patent applications at no cost to GEH and that payments
    were made for GEH in accordance with the Service Agreement
    with W.L. Gore.
    • [An economist for Petitioners] agreed that W.L. Gore and GEH
    had globally integrated goals and that a synergy existed between
    W.L. Gore and GEH due to the relationship between patents and
    products.
    • Testimony from [ ] Petitioners’ witnesses consistently suggested
    that nearly all of the third-party licenses came about in order to
    produce benefits for W.L. Gore or for the “W.L. Gore family of
    companies.”
    • In 1996, W.L. Gore was experiencing some negative cash flow
    when W.L. Gore asked FVI for a line of credit to meet current
    operating needs which continued through 1999. The inter-
    company loans reflected the intercompany dependence of FVI.
    • The audits reflected through the inter-corporate transactions and
    Service Agreement that the Delaware Holding Companies relied
    on W.L. Gore for revenues and services.
    
    Id. at 516-17
    (alterations in original) (footnote omitted).
    The Court then summarized the four primary factual conclusions that led the Tax
    Court to properly rule that GEH and FVI lacked economic substance as business entities
    separate from Gore:
    [1] the subsidiaries’ dependence on Gore for their income, [2] the
    circular flow of money between the subsidiaries and Gore, [3] the
    subsidiaries’ reliance on Gore for core functions and services, and
    [4] the general absence of substantive activity from either subsidiary
    that was in any meaningful way separate from Gore.
    
    Id. at 517.
    17
    According to GEH and FVI, however, SYL was distinguishable, because GEH and
    FVI “engaged in more substantive activities than those in SYL.” 
    Id. at 519.
    Specifically,
    “GEH acquired patents from third parties, licensed patents to third parties, and paid
    substantial fees for outside legal counsel and other services.” 
    Id. The Court
    characterized
    these activities as “more ‘window dressing’ than the SYL subsidiaries,” but concluded that
    “these additional trappings do not imbue GEH and FVI with substance as separate
    entities.” 
    Id. (Emphasis in
    original). The Court elaborated: “Indeed, Gore permeates the
    substantive activities of both GEH and FVI. Petitioners’ employees and operations are so
    intertwined with Gore as to be almost inseparable, as the ‘Legal Services Consulting
    Agreement,’ and reliance on Gore—for everything from professional services, to things
    like office space—so indicate.” 
    Id. at 519-20.
    C. Synopsis of SYL and Gore
    As previously stated, under SYL and Gore a nexus or minimal contacts with the
    State of Maryland that satisfies the constitutional requirements for income taxation by
    Maryland can be established when a foreign wholly owned subsidiary lacks economic
    substance as a business entity separate and apart from its parent company that does business
    in Maryland. See 
    Gore, 437 Md. at 517-18
    ; 
    SYL, 375 Md. at 106
    . Whether a subsidiary
    lacks economic substance as a separate business entity is to be determined on a case by
    case basis, by considering four general factors.8 
    Gore, 437 Md. at 517
    .
    8
    The Court of Appeals did not indicate in Gore that these factors were exhaustive.
    See 
    Gore, 437 Md. at 517
    .
    18
    First, a court should consider how dependent a subsidiary is on its parent company
    for income. 
    Id. at 519.
    Gore and SYL instruct that a court should consider the amount of
    income a subsidiary receives from its parent company or other companies owned by the
    parent company. 
    Id. at 515,
    517; 
    SYL, 375 Md. at 84
    , 86, 94. A court also should consider
    how much income is generated from third parties and how that income may compare with
    other sources of the subsidiary’s income. See 
    Gore, 437 Md. at 517
    .
    Second, a court should consider whether there is a circular flow of money from the
    parent company to the subsidiary and then back to the parent. 
    Id. at 515;
    SYL, 375 Md. at
    84
    , 86, 96. SYL and Gore teach us that the flow of money back to the parent can be
    evidenced in several different ways, such as dividends and loans. See 
    Gore, 437 Md. at 515
    . At its core, this inquiry is whether the parent is the one who controls the flow of
    money and ultimately receives back the money paid to the subsidiary, subject to any
    expenses incurred by the subsidiary.
    Third, a court should consider how much the subsidiary relies on the parent for its
    core functions and services. Included in the core functions utilized by the subsidiary are
    office space and equipment, personnel, and corporate services. Id.; 
    SYL, 375 Md. at 86
    -
    88, 96. The corporate services provided by the parent can include cash management,
    marketing, purchasing, accounting, payroll, tax services, research and development, and
    human resources. 
    Gore, 437 Md. at 515
    ; 
    SYL, 375 Md. at 95-96
    .
    The last factor is a “catch all” to the rest—whether the subsidiary has substantive
    activity that is “in any meaningful way separate from” its parent. 
    Gore, 437 Md. at 517
    (emphasis added). Here, a court should consider whether the subsidiary creates, invents,
    19
    or makes anything that is independent of the parent company. 
    Id. at 516;
    SYL, 375 Md. at
    106
    . Also important is whether there exists functional integration and control by the parent
    through stock ownership, as well as common officers, directors, and employees. See 
    Gore, 437 Md. at 515
    ; 
    SYL, 375 Md. at 98
    . In sum, a court should consider the subsidiary’s
    overall dependence on the parent in the former’s structure and operations. See 
    Gore, 437 Md. at 521
    ; 
    SYL, 375 Md. at 106
    .
    D. Tax Court’s Ruling in the Instant Case
    After a two-day hearing that consisted of factual stipulations, testimony, and
    thousands of pages of exhibits, the Tax Court issued a Memorandum of Grounds for
    Decision. In considering whether Brands had economic substance as a business entity
    separate from ConAgra, the court made the following factual findings:
    In April, 1996, ConAgra incorporated Brands to hold and enforce
    trademarks, conduct central advertising for corporate brands, and
    achieve other corporate efficiencies, including tax savings. Brands
    was capitalized by ConAgra[ ], which also provided its board of
    directors and officers from among the corporate executive corps. In
    late 1996, the parent and three ConAgra subsidiaries – Beatrice
    Foods, Inc., Hunt-Wesson, and Swift-Eckrich contributed 46
    trademark groups to Brands in exchange for 2,207 shares of
    [Brands’s] common stock. Thereafter, Brands held the 46 initial
    trademark groups and subsequently acquired numerous others from
    these entities.
    Brands was physically housed on the ConAgra corporate
    campus in Omaha. It rented space and equipment from the corporate
    parent. Brands had its own officers, who were actually paid by
    Brands, although their payroll was serviced by corporate. Brands
    gradually acquired several employees, and had as many as 23
    employees in the latter part of the period in question.
    Brands licensed the ConAgra trademarks back to the ConAgra
    subsidiaries from which they had been acquired, although in a few
    20
    cases, Brands also licensed ConAgra trademarks to third-party
    corporations. Brands[’s] most significant activity was conducting
    national advertising campaigns for the trademark brands. Brands’[s]
    employees performed quality control for the licensed brands, and
    monitored trademark infringements over the time periods in
    question. In exchange for the licensed trademarks, the licensees paid
    annual royalties to Brands, which was the primary source of
    Brands’[s] income, all of which was paid back to the ConAgra parent
    in the form of inter-company payments of various types.
    Brands was organized in part to obtain a reduction in taxes. One
    of the advantages of organizing and using [Brands] to own and
    manage trademarks for the ConAgra family of companies was a
    potential royalty deduction from income taxes that would be claimed
    by ConAgra companies in those states that did not require combined
    income tax reporting.
    Brands was entirely owned, directly and indirectly, by ConAgra
    [ ], the parent corporation. ConAgra itself held 1,000 shares of
    Brands (45%), while the remaining 1,207 shares were owned by
    three of ConAgra’s wholly owned subsidiaries, Swift-Eckrich, Inc.,
    Hunt-Wesson, Inc., and Beatrice Cheese, Inc. In its fiscal year
    ending May, 1997 through May, 2004, [Brands] received millions of
    dollars of royalty income from ConAgra companies doing business
    and filing tax returns in Maryland.
    The evidence suggests during the entire period at issue,
    ConAgra utilized centralized legal services, tax services, human
    resources (including payroll), treasury functions, cash management,
    marketing, corporate relations, information services, research &
    development, purchasing, accounting, and general corporate
    management. In fact, Brands itself was organized for the purpose of
    centralizing control over trademarks and conducting centralized
    national advertising ConAgra-wide.
    ConAgra corporate executives were routinely assigned to
    interlocking directors’ boards of the several subsidiary corporations;
    officers were assigned to various subsidiaries from an existing
    central pool of executives; and many corporate officers were
    assigned as special portfolio officers to numerous subsidiaries.
    ConAgra [ ] had a vice-president for taxes. That officer was
    simply assigned as the vice president for taxes to Brands and to many
    21
    other subsidiaries. Likewise, ConAgra[ ]’s corporate secretary was
    cross-assigned as the corporate secretary for Brands, Hunt-Wesson,
    Swift-Eckrich, and Beatrice Foods. Kenneth DiFonzo testified by
    deposition that he was assigned as an officer and director to so many
    different subsidiaries that he could only recall the names of a few of
    the subsidiaries to which he was assigned. The annual assignment
    of officers to subsidiaries [was] effectively carried out by the
    ConAgra [ ] corporate secretariat, which circulated “consents in lieu
    of” annual meetings and boards of the various entities signed the
    consents.
    From a revenue standpoint, Brands depended for the vast
    majority of its annual revenue on royalty payments from
    ConAgra and its subsidiaries. All profits from its operation were
    transferred back to ConAgra in annual payments called “cost of
    capital” payments and through other internal financial
    arrangements. The payments to and from ConAgra and its subs,
    and to and from Brands in particular, were entirely circular.
    Brands could not have functioned as a corporate entity
    without the support services its received from “corporate.” All
    of Brands’[s] everyday support services – ranging from its
    physical housing to payroll, accounting, cash management, tax
    services, funding of legal services, capital requirements,
    financing, executive staffing, and information services – were
    supplied by its corporate parent.
    The facts indicate functional integration and control
    through stock ownership, as well as common employees,
    directors and officers. The functional source of Brands[’s]
    income is derived from the ideas and discoveries generated by
    ConAgra Corporate. The circular flow of money is traced by
    and through the valuable trademarks.
    In addition, the facts also indicate Brands’[s] reliance on
    ConAgra corporate personnel, office space and corporate
    services. The tax returns and other financial data reflect the
    lack of separate substantial activity of Brands.
    (Emphasis added).
    22
    From the above facts, the Tax Court concluded that Brands was sufficiently similar
    to the subsidiary companies in SYL and Gore, and thus “lacked any economic substance
    separate from its parent(s).” (Emphasis in original). Accordingly, the Tax Court held that
    Brands was subject to income taxation by Maryland.
    E. Challenges to the Tax Court’s Factual Findings
    Unlike the subsidiaries in SYL and Gore, Brands begins its attack on the Tax Court’s
    decision by challenging several of the court’s factual findings. First, Brands argues that
    there is not substantial evidence to support the following findings by the Tax Court: 1)
    “[I]n exchange for the licensed trademarks, the licensees paid annual royalties to Brands,
    which was the primary source of Brands’[s] income, all of which were paid back to the
    ConAgra parent in the form of inter-company payments of various types[;]” and 2) “[A]ll
    profits from its operation were transferred back to ConAgra in annual payments called ‘cost
    of capital’ payments and through other internal financial arrangements. The payments to
    and from ConAgra and its subs, and to and from Brands in particular, were entirely
    circular.” (Some alterations in original) (emphasis omitted). Brands contends that “the
    record clearly reflects that Brands neither paid dividends to its shareholders nor made any
    loans to ConAgra or any of its affiliates.” According to Brands, the record “clearly reflects
    that Brands made no payments for ‘cost of capital.’” In short, Brands’s first argument
    appears to challenge the Tax Court’s ultimate factual finding that Brands and ConAgra had
    a circular flow of money.
    At the outset, we observe that the Tax Court did not make any factual findings
    pertaining to dividends or loans from Brands to ConAgra, and therefore, conclude that
    23
    there is no merit to Brands’s assertion that the court made any such findings. We agree
    with Brands that the record does not reflect that there were any “cost of capital” payments
    made by Brands. Nevertheless, there is substantial evidence to support the Tax Court’s
    ultimate factual finding that there was a circular flow of money between Brands and
    ConAgra.
    The Tax Court found that the royalties paid to Brands by ConAgra and its
    subsidiaries were paid back to ConAgra “in the form of inter-company payments of various
    types” and “through other internal financial arrangements.” (Emphasis added). These
    “inter-company payments” and “other internal financial arrangements[,]” in our view, refer
    to the cash management system that ConAgra and its subsidiaries, including Brands,
    employed. Eric Johnson, the “Senior Director in the Corporate Tax Department for
    ConAgra[,]” testified at the Tax Court hearing about the cash management system,
    explaining in relevant part:
    [BRANDS’S COUNSEL]: Could you explain to us what a cash
    management system is and how it works?
    [JOHNSON]: In a multi-entity organization like ConAgra, we
    utilize a central cash management system to manage cash. And so,
    in our structure, ConAgra [ ] basically serves as the bank.
    [BRANDS’S COUNSEL]: Is ConAgra [ ] the parent?
    [JOHNSON]: I’m sorry. ConAgra [ ], the parent company, serves
    as the bank, if you will. And to the extent a subsidiary either
    earns revenue or cash, that cash is swept up to ConAgra [ ]. To
    the extent a subsidiary needs to use cash, the cash comes down
    from ConAgra [ ]. ConAgra [ ] takes, if we’re lucky, excess cash,
    invests that, or it’s the ultimate entity that goes out and get[s]
    loans to the extent we need loans from third parties to operate.
    24
    [BRANDS’S COUNSEL]: Is [ ] Brands a cash user or a cash
    generator?
    [JOHNSON]: [ ] Brands is a cash generator.
    [BRANDS’S COUNSEL]: So their cash would be swept by
    ConAgra [ ] into a central bank?
    [JOHNSON]: That’s correct.
    [BRANDS’S COUNSEL]: And how is that reflected on [ ]
    Brands’[s] accounting records?
    [JOHNSON]: It’s through what we call an inter-company account.
    And so if you look at…[ ] Brands’[s] balance sheet, you will see, I
    believe it’s categorized in the other current assets, an inter-company
    account that basically accumulates all those cash sweeps or cash
    receipts going either way through those accounts.
    [BRANDS’S COUNSEL]: So if we were to look at a balance sheet
    for [ ] Brands, we would find an asset there that reflects the cash?
    [JOHNSON]: Yes.
    (Emphasis added).
    Johnson further explained the relationship of the cash management system and
    Brands’s net royalty income as reflected on Brands’s balance sheet:
    [BRANDS’S COUNSEL]: So if I were to look at the balance sheets
    that are attached to these federal returns, would I see a continual
    growth in retained earnings which reflects the net income that
    Brands has earned in each year?
    [JOHNSON]: Yes.
    [BRANDS’S COUNSEL]: Okay. And then, as far as the cash is
    concerned, that might be reflective of the royalty income that’s
    swept pursuant to the centralized cash management system?
    25
    ***
    [JOHNSON]: That’s true.
    [BRANDS’S COUNSEL]: Okay.
    [JOHNSON]: So retained earnings is basically increased by net
    income and would be decreased by net losses. It could be from our
    returns, it could also be decreased by a distribution.
    [BRANDS’S COUNSEL]: But I believe you indicated there were
    no distributions, that everything’s swept.
    [JOHNSON]: Yes. For [ ] Brands there are no distributions.
    [BRANDS’S COUNSEL]: And then is there an asset on the balance
    sheet that reflects the cash sweep?
    [JOHNSON]: There’s an asset on the balance sheet that reflects the
    cash, basically, any cash movements. So cash sweeps, any payment
    of expenses that [ ] Brands had that cash came down from [ConAgra]
    called the inter-company account.
    Kenneth DiFonzo, ConAgra’s Vice President, also testified about the cash
    management system in his deposition, portions of which were admitted into evidence by
    stipulation. DiFonzo explained that ConAgra subsidiaries did not pay dividends, because
    it would have “created additional accounting where none was needed,” and the cash
    management system produced the same result. DiFonzo confirmed the operation of the
    cash management system: “Every single dollar that flowed into the cash coffers of [the
    subsidiaries] and thereby into the company, they were given interest credit for. Every
    single dollar that they expended they were charged for.” (Emphasis added).
    Taking the testimonies of Johnson and DiFonzo together, the evidence showed that
    the royalties paid to Brands by ConAgra and its subsidiaries were immediately “swept up
    26
    to ConAgra,” and except for the cash needed to pay Brands’s expenses and the “interest
    credit” given to Brands, there was no expectation of a repayment to Brands nor any
    limitations on ConAgra’s use of the cash. As a result, the cash management system allowed
    ConAgra to use all of Brands’s net royalty income from the date of the latter’s
    incorporation, which amounted to over $1.2 billion as of May 2004, according to the
    retained earnings listed on Brands’s balance sheet.
    As stated previously, we review the Tax Court’s factual findings by determining
    whether they are supported by substantial evidence.9 
    Gore, 437 Md. at 504
    . We conclude
    that based on this record, “a reasoning mind could have reached the factual conclusion” of
    the Tax Court that there was a circular flow of money, i.e., royalties, from ConAgra and its
    subsidiaries to Brands and back to ConAgra.
    Second, Brands contends that there is “nothing in the record supporting” the Tax
    Court’s finding that “Brands could not have functioned as a corporate entity without the
    support services it received from ‘corporate’ and that among other things, physical housing,
    payroll and funding of legal services were ‘supplied by its corporate parent.’” According
    to Brands, the record demonstrates that Brands paid ConAgra for all of the services that
    ConAgra provided.
    9
    Although both parties agree that Brands’s challenges pertain to the Tax Court’s
    factual findings, we note that, even if Brands’s challenges could be considered challenges
    concerning a mixed question of law and fact, our conclusion would not be altered, because
    we also review mixed questions of law and fact under a substantial evidence standard. See
    
    Gore, 437 Md. at 504
    -05.
    27
    Based on Brands’s citation to the record, Brands is challenging the following factual
    finding of the Tax Court:
    Brands could not have functioned as a corporate entity without the
    support of services it received from “corporate.” All of Brands[’s]
    everyday support services – ranging from its physical housing, to
    payroll, accounting, cash management, tax services, funding of legal
    services, capital requirements, financing, executive staffing, and
    information services – were supplied by its corporate parent.
    The above finding of the Tax Court did not address whether Brands paid for the
    services supplied by ConAgra. It simply stated that ConAgra “supplied” certain services.
    In a stipulation filed in the Tax Court, Brands agreed to the following facts: “ConAgra [ ]
    was a parent company with corporate functions, including tax services, human resources
    services, treasury functions, cash management, marketing, corporate relations, information
    services, and general management. These services were supplied to the parent company’s
    subsidiaries.” Brands further stipulated that ConAgra supplied additional services to
    Brands from 1996 to 2005, including “central purchasing[,]” “centralized advertising[,]”
    “centralized accounting[,]” “reviewed significant contracts[,]” “centralized corporate
    research and development[,]” and “supplied human resources services … includ[ing]
    payroll services.” Accordingly, there was substantial evidence for the Tax Court to find
    that ConAgra supplied Brands with the above-referenced services.
    Lastly, Brands argues there is not substantial evidence to support the Tax Court’s
    finding that “Brands’[s] tax returns and other financial data reflect the lack of separate
    substantial activity of Brands.” Brands contends that its tax returns and financial records
    reflect that it paid employees, paid rent, accrued expenses, and owned assets.
    28
    Consistent with Brands’s assertion, the Tax Court did make factual findings that
    Brands had expenses for rent and employees. Such findings, however, do not undermine
    the court’s factual conclusion that Brands lacked substantive activity separate from
    ConAgra and its wholly owned subsidiaries. For example, the court found that “[t]he
    functional source of Brands[’s] income is derived from the ideas and discoveries generated
    by ConAgra”— not the ideas and discoveries of Brands. Indeed, Brands stipulated that
    ConAgra conducted centralized research and development. Moreover, even though Brands
    had license agreements with third parties, these revenues generated less than one percent
    of Brands[’s] revenue, except for 1997 when third party royalties generated just under four
    percent of Brands’s revenue. As the Court of Appeals has instructed, “[i]t is not our place
    to make an independent original estimate of or decision on the evidence[,]” and we decline
    to do so here, especially when Brands has failed to direct this Court to any specific
    reference to the record, other than the broad statement that Brands incurred expenses, in its
    attempt to undermine the Tax Court’s factual conclusion that Brands lacked substantive
    activity separate from ConAgra. See 
    Gore, 437 Md. at 504
    (some alterations in original)
    (internal quotation marks omitted).
    F. Analysis
    Brands argues that the Tax Court erred in relying on SYL and Gore to conclude that
    Brands lacked economic substance as a business entity separate from ConAgra.
    Specifically, Brands contends that, unlike the subsidiaries in Gore and SYL, (1) Brands’s
    income was not solely from ConAgra but from ConAgra’s subsidiaries and third parties;
    (2) Brands did not issue dividends or loans; (3) Brands promoted, marketed, and defended
    29
    its intellectual property; (4) Brands incurred operating expenses relative to its income; (5)
    the motivation behind forming Brands extended beyond taxation; and (6) Brands had
    twenty-three employees.10 Brands further contends that the Tax Court placed too much
    emphasis on the fact that ConAgra provided Brands with many administrative functions,
    because “it is common in today’s corporate world that administrative functions are
    centralized to provide efficiencies for the entire group.” We are not persuaded.
    In its opinion, the Tax Court found that “Brands depended for the vast majority of
    its annual revenue on royalty payments from ConAgra and its subsidiaries.” Royalty
    payments were generated solely because (1) ConAgra and three subsidiaries assigned
    Brands their trademarks in exchange for Brands’s stock, and (2) Brands licensed the same
    trademarks back to ConAgra and those subsidiaries. The fact that the subsidiaries, or their
    successors, paid royalties to Brands does not call into question the Tax Court’s finding,
    because the subsidiaries were wholly owned by ConAgra and the royalty payments flowed
    from the subsidiaries to Brands and then back to ConAgra. The court did consider third
    party revenues, but again found that the “vast majority” of Brands’s revenue came from
    ConAgra and its subsidiaries. In Gore, the Tax Court acknowledged that there were royalty
    payments to GEH from third parties but determined that the payment of royalties from third
    10
    In its Brief, Brands broadly asserts several other “facts” that it contends are
    supported by the record, and that the Tax Court should have considered in its ruling.
    Brands, however, does not provide any argument as to why the court should have made
    those factual findings. As previously stated, “it is the agency’s province to resolve
    conflicting evidence and where inconsistent inferences can be drawn from the same
    evidence it is for the agency to draw the inferences.” 
    Gore, 437 Md. at 504
    . We will,
    therefore, review the court’s ruling based on its “findings and reasons set forth” in its
    opinion. 
    Id. at 503.
    30
    parties did not negate GEH’s “dependence on Gore for [its] income.” 
    Gore, 437 Md. at 517
    . Similarly, the Tax Court had substantial evidence to conclude that Brands was
    dependent on ConAgra and its subsidiaries for Brands’s income; Brands’s third party
    revenue never exceeded four percent in any tax year.
    As described in detail above, the Tax Court found that there was a circular flow of
    money from ConAgra and its subsidiaries to Brands and back to ConAgra. We concluded
    that there was substantial evidence for the Tax Court to make such a finding. Brands is
    correct that it did not pay dividends or make loans, as was the case with the subsidiaries in
    SYL and Gore. See 
    SYL, 375 Md. at 85-86
    , 96; 
    Gore, 437 Md. at 515
    . In the instant case,
    however, paying dividends or making loans was not necessary to create the circular flow
    of money, because the cash management system produced the same result. All of the cash
    received by Brands was “swept up to ConAgra,” and only the cash needed for expenses
    was returned to Brands. Therefore, Brands was similar to the subsidiaries in SYL and Gore
    with regard to the circular flow of money between the parent and subsidiary.
    The Tax Court acknowledged that “Brands[’s] most significant activity was
    conducting national advertising campaigns for the trademark brands.               Brands[’s]
    employees performed quality control for the licensed brands, and monitored trademark
    infringements over the time periods in question.” Nevertheless, the court found that there
    was “functional integration and control [by ConAgra] through stock ownership, as well as
    common employees, directors and officers.” The court elaborated: “ConAgra corporate
    executives were routinely assigned to interlocking directors’ boards of the several
    subsidiary corporations; officers were assigned to various subsidiaries from an existing
    31
    central pool of executives; and many corporate officers were assigned as special portfolio
    officers to numerous subsidiaries.” Specifically, the vice president of tax for ConAgra was
    also assigned to be the vice president of tax for Brands. The secretary for ConAgra was
    also assigned to be the secretary for Brands, Hunt-Wesson, Swift-Eckrich, and Beatrice
    Foods. Moreover, DiFonzo, the ConAgra vice president and member of the board of
    directors for Brands, testified that “he was assigned as an officer and director to so many
    different subsidiaries that he could only recall the names of a few of the subsidiaries to
    which he was assigned.” The court also found that “[t]he functional source of Brands[’s]
    income [was] derived from the ideas and discoveries generated by ConAgra[.]” Like Gore,
    ConAgra “permeates the substantive activities” of Brands. 
    Gore, 437 Md. at 519-20
    .
    Although Brands was organized to centralize control over the trademarks used by
    ConAgra and its subsidiaries, the Tax Court found that “Brands was [also] organized in
    part to obtain a reduction in taxes.” Brands appears to argue that the Tax Court should
    have given more weight to the “non-tax business reasons for establishing Brands.” The
    Court of Appeals, however, explained in Gore that “the motivation behind creating the
    entities…is not dispositive.” 
    Id. at 519.
    In our view, the court properly considered the
    motives behind Brands’s creation.11
    11
    Brands also appears to argue that it is distinguishable from the subsidiaries in
    Gore because Brands paid state income taxes while the subsidiaries in Gore and SYL did
    not pay any state income taxes. Brands does not elaborate further, but to the extent that it
    is arguing that paying taxes lessens tax avoidance as a motive for Brands’s formation, we
    reject that argument because, as stated above, the motivations behind Brands’s formation
    are not dispositive. Gore, 
    437 Md. 519
    .
    32
    The Tax Court further acknowledged that Brands had twenty-three employees in the
    latter part of the tax period in question. Brands argues that its twenty-three employees is
    an important factor in determining economic substance, but Brands fails to direct this Court
    to, and did not adduce before the Tax Court, any evidence demonstrating the nature of these
    employees’ duties or the compensation of each employee. See 
    id. at 520-21
    (determining
    that the Tax Court did not err in addressing only certain aspects of third party activity
    because of the lack of “specificity and comprehensiveness” of the record). The mere
    number of employees, without more, does not convince us that Brands is sufficiently
    distinguishable from the subsidiaries in SYL and Gore.
    Finally, the Tax Court found that Brands relied on ConAgra for most, if not all, of
    its administrative functions. Brands argues that the court placed too much emphasis on
    this factor, but we disagree with this interpretation of the court’s opinion. As outlined
    above, the court took into consideration many factors other than the administrative
    functions that ConAgra provided Brands in arriving at its conclusion that Brands lacked
    economic substance as a separate business entity.
    Therefore, we hold that there was substantial evidence to support the Tax Court’s
    findings of (1) Brands’s dependence on ConAgra and its subsidiaries for the “vast
    majority” of its income, (2) the circular flow of money from ConAgra and its subsidiaries
    to Brands and back to ConAgra, (3) Brands’s reliance on ConAgra for its core functions,
    and (4) Brands’s lack of any meaningful substantive activity separate from ConAgra. From
    those factual findings, the court properly applied the teachings of SYL and Gore to conclude
    that Brands lacked economic substance as a business entity separate from ConAgra.
    33
    Because a portion of Brands’s income was produced from the business activity of ConAgra
    and its subsidiaries in Maryland, the court correctly held that there was a sufficient nexus
    and minimum contacts to justify Maryland’s taxation of that portion of Brands’s income.
    Nevertheless, Brands makes two additional challenges to the Tax Court’s ruling that
    we must address. The first challenge is that the court applied the unitary business principle
    in determining that Brands lacked economic substance as a separate entity. According to
    Brands, the court focused solely on the relationship between Brands and ConAgra and its
    subsidiaries and not enough on whether Brands had substantial economic activity. We
    disagree.
    The Court of Appeals explained in Gore that “[t]he unitary business principle
    enables taxation by apportionment when the characteristics of functional integration,
    centralized management, and economies of scale are present.” 
    Id. at 508
    (emphasis added)
    (internal quotation marks omitted). “[T]he principle does not confer nexus to allow a state
    to directly tax a subsidiary based on the fact that the parent company is taxable and that
    the parent and subsidiary are unitary.” 
    Id. at 509
    (emphasis in original). In other words,
    the unitary business principle is not sufficient to satisfy the “minimum contacts” and
    “nexus” requirements of the Due Process Clause and the Commerce Clause. 
    Id. The Court
    did, however, hold in Gore that,
    [a]though the unitary business principle and economic substance
    inquiry under SYL are distinct inquires with distinct purposes, there
    is no reason—based either in case law or logic—for holding that the
    factors that indicate a unitary business cannot also be relevant in
    determining whether subsidiaries have no real economic substance
    as separate business entities.
    34
    
    Id. at 518.
    We do not read the Tax Court’s opinion as using factors that are only applicable to
    the unitary business principle. The court expressly stated that “the unitary business
    principle does not confer nexus to allow a state to directly tax a subsidiary[.]” It is this
    Court’s view that the Tax Court properly considered those factors set forth in SYL and Gore
    and did not apply the unitary business principle in its analysis of Brands’s economic
    substance as a separate business entity.
    Brands’s last attempt to distinguish Gore and SYL is to attack the nexus of ConAgra
    and its subsidiaries with Maryland. Brands argues that, unlike the companies at issue in
    SYL and Gore, “neither ConAgra, nor any of its affiliates, operated retail stores or
    manufacturing plants in Maryland.” Brands continues: “Because none of Brands[’s]
    licensees operated retail stores or manufacturing plants in Maryland, they did not use the
    Intangible Assets in Maryland.” In essence, Brands argues that without ConAgra or its
    subsidiaries having a physical presence in Maryland, Brands does not have a sufficient
    nexus or minimal contacts with the State and Brands did not earn income from the business
    operations of ConAgra and its subsidiaries in Maryland. Brands’s argument is without
    merit.
    We acknowledge that in Gore, Gore operated factories in Maryland and presumably,
    although not explicitly stated, filed Maryland tax returns. 
    Id. at 500.
    In SYL, Crown Parent
    had Maryland manufacturing plants, and Syms operated retail stores in Maryland. 
    SYL, 375 Md. at 81
    , 92. The Court of Appeals, however, noted in SYL that both parent
    companies filed Maryland taxes for the years in question. 
    Id. The United
    States Supreme
    35
    Court made clear in Wayfair that there is no physical presence requirement for a state to
    tax a corporation under the Due Process Clause or the Commerce 
    Clause. 138 S. Ct. at 2094
    (“Rejecting the physical presence rule is necessary to ensure that artificial
    competitive advantages are not created by this Court’s precedents. This Court should not
    prevent States from collecting lawful taxes through a physical presence rule that can be
    satisfied only if there is an employee or a building in the State.”). In the instant case, the
    parties stipulated that ConAgra “conducted operations in Maryland” and filed corporation
    income tax returns in Maryland. The parties also stipulated that certain subsidiaries of
    ConAgra filed Maryland corporation income tax returns. In our view, the “operations” of
    ConAgra in Maryland and the filing of Maryland corporation income tax returns by
    ConAgra and its subsidiaries in Maryland are sufficient to establish that those companies
    conducted income generating activities within the State, and their lack of a physical
    presence in Maryland does not sever the nexus between Brands and Maryland. See
    Classics Chicago, Inc. v. Comptroller, 
    189 Md. App. 695
    , 715-16 (2010) (“[T]he basis of
    a nexus sufficient to justify taxation . . . was the economic reality of the fact that the parent’s
    business in the taxing state was what produced the income of the subsidiary.”)
    Accordingly, we find no error in the Tax Court’s ruling.
    III.   Apportionment Formula
    A. A Brief Background on Income Tax Apportionment
    To understand the Comptroller’s assessment, we find it useful to summarize in
    general terms the mechanics of how Maryland corporate income tax is calculated when a
    36
    corporation conducts business both in and outside of the State.12 And more specifically,
    what an apportionment formula is under Maryland law. In doing so, we will review the
    statutory and regulatory landscape applicable to the taxing years of 1996 to 2003.13
    Generally, in calculating the taxable income of a corporation, one begins with the
    corporation’s federal taxable income. Md. Code (1988, 1996 Supp.), § 10-304(1) of the
    Tax General Article (“TG”). From the federal taxable income, adjustments, if applicable,
    are made to either increase or decrease the Maryland taxable income. TG §§ 10-304-310.
    The result of these adjustments is called the corporation’s “Maryland modified income.”
    TG § 10-301, 304.
    In the relevant tax years, the Tax General Article provided that, when a corporation
    conducts “business in and out of the State, the corporation shall allocate to the State the
    part of the corporation’s Maryland modified income that is derived from or reasonably
    attributable to the part of its trade or business carried on in the State[.]” TG § 10-402(a)(2),
    12
    As one might imagine, the calculation of the ultimate tax levied against a
    corporation can be very complicated, from the adjustments to the tax credits to the
    exemptions. And of course, depending on what type of business the corporation engages
    in, there could be different methods of calculating Maryland income tax.
    13
    From 1996 to 2000, the relevant, applicable statutes in this case were not changed.
    In 2001, however, the General Assembly adopted 2001 Md. Laws Ch. 633, which amended
    Maryland Code (1988, 1994 Repl. Vol., Supp. 2000), § 10-402 of the Tax General Article
    (“TG”). Most notable was the addition of “or the single sales factor formula method” to
    Section 10-402(d)(2). See 2001 Md. Laws Ch. 633. These amendments and their
    applicability to the apportionment of income were not argued in this appeal and thus such
    amendments do not alter our conclusion.
    37
    amended by 2018 Md. Laws Ch. 341-42.14 There are three methods of apportionment. The
    first is called “separate accounting[,]” which is applied if “[i]t is practical[] and [t]he
    activity of the corporation within this State is nonunitary.” TG § 10-402(b), amended by
    2018 Md. Laws Ch. 341-42;15 COMAR 03.04.03.08(F)(3). Given the unitary business of
    Brands, ConAgra, and the latter’s subsidiaries in Maryland, separate accounting is not
    used.
    The second formula is called the “three-factor apportionment formula.” TG § 10-
    402(c), amended by 2018 Md. Laws Ch. 341-42.16 As explained by the Court of Appeals
    in NCR Corp. v. Comptroller, the three-factor apportionment formula is determined
    by using [ ] three-factor[s] (sales, property and payroll) .
    . . each “factor” being a fraction. The numerator of the
    sales factor, for example, is the amount of a corporation’s
    in-state sales; the denominator of the sales factor is the
    total amount of a corporation’s in-state and out-of-state
    sales. The property and payroll factors are computed in
    the same manner.
    14
    In 2018, the General Assembly made amendments to TG § 10-402. The
    amendments made only stylistic changes to TG § 10-402(a)(2) and recodified it as TG §
    10-402(b)(2). See 2018 Md. Laws Ch. 341 at 1604. In this opinion, we will refer to the
    statutory provisions as they were codified during the relevant tax years.
    15
    This provision was unchanged by the 2018 amendments and is now codified as
    TG § 10-402(c)(1). See 2018 Md. Laws Ch. 341 at 1604.

    Although the 2018 amendments did not change the basic structure of the 3-factor
    formula, they did change the amount by which the sales factor is multiplied, as well as the
    total denominator. Because the Comptroller, in its discretion, chose not to use the 3-factor
    formula in the instant case, and we uphold that choice, see Section III.C, infra, these
    changes do not affect our analysis herein. See 2018 Md. Laws Ch. 342 at 1615-16.

    42; COMAR 03.04.03.08(C). To calculate the apportionment factor, one must average the
    property factor, payroll factor and “twice the sales factor.” TG § 10-402(c), amended by
    2018 Md. Laws Ch. 341-42. In other words, the apportionment factor is calculated as
    follows:
    (( 𝑀𝑎𝑟𝑦𝑙𝑎𝑛𝑑  𝑆𝑎𝑙𝑒𝑠
    𝐴𝑙𝑙 𝑆𝑎𝑙𝑒𝑠
    X 2) +
    𝑀𝑎𝑟𝑦𝑙𝑎𝑛𝑑 𝑃𝑟𝑜𝑝𝑒𝑟𝑡𝑦
    𝐴𝑙𝑙 𝑃𝑟𝑜𝑝𝑒𝑟𝑡𝑦
    + 𝑀𝑎𝑟𝑦𝑙𝑎𝑛𝑑 𝑃𝑎𝑦𝑟𝑜𝑙𝑙
    𝐴𝑙𝑙 𝑃𝑎𝑦𝑟𝑜𝑙𝑙
    )÷4
    See 
    NCR, 313 Md. at 141
    (expressing the three-factor formula in place at the time prior to
    the 1992 amendments in a similar manner). This apportionment factor is then multiplied
    by the Maryland modified income. 
    Id. at 142;
    TG § 10-301.
    The third apportionment formula is an altered formula that is created by the
    Comptroller in his or her discretion, as provided for in TG § 10-402(d):17
    (d) Determination — by Comptroller. — To reflect clearly the
    income allocable to Maryland, the Comptroller may alter, if
    circumstances warrant, the methods under subsections (b) and (c) of
    this section, including:
    (1) the use of the separate accounting method;
    (2) the use of the 3-factor double weighted sales factor formula
    method or the single sales factor formula method;
    (3) the weight of any factor in the 3-factor formula;
    (4) the valuation of rented property included in the property
    factor; and
    (5) the determination of the extent to which tangible personal
    property is located in the State.
    17
    The 2018 amendments made no changes to this provision, but recodified it as TG
    § 10-402(e). See 2018 Md. Laws Ch. 341 at 1611.
    39
    Once one of these formulas is applied, the result is the corporation’s Maryland
    taxable income. TG § 10-301. The applicable corporate tax rate (seven percent from 1996
    to 2003) is then applied to a corporation’s Maryland taxable income resulting in the tax
    owed to the State. TG § 10-105(b), amended by 2007 (Special Session) Md. Laws Ch. 3.18
    B. The Assessment and the Tax Court’s Ruling in Brands
    Before the Tax Court, it was stipulated that, on August 30, 2007, the Comptroller
    assessed Brands the following taxes, interest, and penalties:
    It was further stipulated that after the above assessment was affirmed by the
    Comptroller in 2009, the following was the assessment:
    18
    In 2007, the General Assembly amended the Tax General article to increase the
    corporate tax rate to 8.25%. 2007 (Special Session) Md. Laws Ch. 3 at 82. Because this
    change only applies to tax years beginning after December 31, 2007, it does not affect the
    amount of tax due in the instant case.
    40
    In considering the Comptroller’s assessment, the Tax Court made the following
    ruling:
    Where nexus is satisfied as in the present case, the Maryland tax
    on a multi-state corporation engaged in interstate business is
    governed by Md. Code Ann., Tax-Gen. [(“TG”)] § 10-402 ([1988,]
    2010 Repl. Vol.). In TG § 10-402, Maryland provides for both
    separate accounting and formulaic apportionment as methods for
    allocating the income of a foreign corporation doing business in the
    State. See TG § 10-402(b) & (c). Formulaic apportionment, unlike
    separate accounting, does not purport to identify the precise
    geographical source of a corporation’s profits; rather, it is employed
    to approximate a corporation’s income that is reasonably related to
    the activities conducted within the taxing State. TG § 10-402(d)
    requires that net income be apportioned to this state on the basis of
    a formula that clearly reflects the income allocable to Maryland. The
    Comptroller may alter, if circumstances warrant, the methods of
    allocating income to Maryland. TG § 10-402(d); COMAR §
    03.04.03.08F.
    The Comptroller’s auditors found that with respect to Brands,
    there were no recorded Maryland sales, no recorded Maryland
    payroll, and no recorded Maryland property. As a result,
    application of the statutory “3-factor apportionment formula”
    provided by TG § 10-402(c) would have yielded an
    apportionment factor of zero. Since a zero apportionment factor
    41
    would not have “reflect[ed] clearly the income allocable to
    Maryland,” the Comptroller’s agents formulated a blended
    apportionment factor. The blended apportionment factor
    utilized by the Comptroller in allocating Brands’[s] income was
    derived directly from the income tax returns of the five ConAgra
    entities that filed in Maryland. The Court finds that the
    Comptroller effectively utilized ConAgra’s own apportionment
    figures in constructing the blended apportionment factor used
    in this case. There is no clear and convincing evidence that the
    Comptroller’s blended apportionment factor is unfair.
    (Some alterations in original) (Emphasis added).
    C. Brands’s Challenges to the Apportionment Formula
    Brands first contends that the Comptroller’s apportionment formula was not
    permitted under TG § 10-402(d). Brands acknowledges that TG § 10-402(d) permits the
    Comptroller to deviate from the three-factor formula set forth in § 10-402(c), but argues
    that the Comptroller failed to demonstrate that the use of the three-factor formula did not
    clearly reflect Brands’s Maryland income.
    The Comptroller responds that “TG § 10-402(d) requires that net income be
    apportioned to this State on the basis of a formula that clearly reflects the income allocable
    to Maryland. The Comptroller may alter, if circumstances warrant, the methods of
    allocating income to Maryland.” The Comptroller explains that the use of the three-factor
    apportionment formula for Brands would have yielded zeros for payroll, property, and sales
    in Maryland, “thus yielding an apportionment factor of zero.”             According to the
    Comptroller, an apportionment factor of zero would not have reflected clearly Brands’s
    income allocable to Maryland. The Comptroller concludes that a blended apportionment
    42
    factor derived from the Maryland income tax returns of ConAgra and its subsidiaries was
    appropriate. We agree with the Comptroller.
    In Gore, GEH and FVI argued that the Comptroller improperly borrowed an
    apportionment formula from Gore to create GEH and FVI’s apportionment 
    formula. 437 Md. at 528-29
    . Like Brands, GEH and FVI advocated an apportionment based upon their
    property and payroll in Maryland, which would have produced an apportionment factor of
    zero. 
    Id. GEH and
    FVI claimed that the Comptroller’s apportionment formula ignored the
    binding regulation of COMAR 03.04.03.08(C)(3)(d). 
    Id. The Court
    of Appeals rejected the argument of GEH and FVI:
    Both TG § 10–402 and COMAR 03.04.03.08 are provisions with
    exceptions. TG § 10–402(d) allows the Comptroller to “alter, if
    circumstances warrant, the methods under subsections (b) and (c) of
    this section[.]” COMAR 03.04.03.08(F)(1) allows the Comptroller
    to alter both a formula or its components where an apportionment
    formula “does not fairly represent the extent of a corporation's
    activity in [the] State[.]” As Respondent correctly points out, the
    three-factor formula . . . would have yielded an apportionment
    factor of zero, which did not fairly represent the subsidiaries’
    activity in Maryland. Thus, a plain reading of either the statute
    or regulation empowers the Comptroller to do precisely that to
    which Petitioners object.
    
    Id. at 529
    (some alterations in original) (emphasis added). Here, too, the Comptroller had
    the discretion to deviate from the three-factor apportionment formula, because an
    apportionment factor of zero did not accurately represent Brands’s activity in Maryland.
    Brands counters that, even if the Comptroller demonstrated the need to deviate from
    the three-factor formula, the Comptroller did not use a method permitted under TG § 10-
    402(d). The Comptroller responds that the Court of Appeals ruled in Gore that it was
    43
    permissible to use a parent company’s apportionment factor in calculating a subsidiary’s
    income tax when the three-factor formula produced a zero apportionment factor for the
    subsidiary.
    TG § 10-402(d) provides that the Comptroller may alter an apportionment formula
    to “reflect clearly the income allocable to Maryland.” In Gore, the Court of Appeals
    permitted the Comptroller to apply Gore’s apportionment factor to calculate the Maryland
    taxable income for both GEH and 
    FVI. 437 Md. at 533
    . In that case, the Court, quoting
    the Tax Court, explained the Comptroller’s assessment as follows:
    The tax calculation utilized by the Comptroller was intended to
    apportion to Maryland only the Delaware Holding Company income
    connected to the operating transactions of W.L. Gore. Expenses
    were deducted from the income if the Delaware Holding Company
    made an affirmative demonstration that the expenses were directly
    related to the income. GEH made no attempt to allocate Delaware
    Holding Company expenses to the W.L. Gore connected income.
    Consequently, GEH’s tax liability was calculated by multiplying
    royalties paid by W.L. Gore times the W.L. Gore apportionment
    formula. For FVI, the tax is calculated by multiplying interest
    paid by W.L. Gore times the W.L. Gore apportionment formula.
    
    Id. at 529
    -30 (emphasis added).
    Like in Gore, the Comptroller used the apportionment factor of Brands’s parent
    company, ConAgra. See 
    id. In the
    instant case, however, the Comptroller used what it
    terms a “blended apportionment factor,” which was derived from the apportionment factors
    of ConAgra and its subsidiaries doing business in Maryland and paying Brands royalties.
    In her testimony before the Tax Court, Mary Wood, the Manager of Corporation Income
    Tax for the Comptroller, explained the origin and effect of the blended apportionment
    factor:
    44
    [WOOD]: This is the blended factor apportionment worksheet that
    I was talking about earlier where it lists on the left side where it
    shows all the parent affiliate companies, those are all of the
    Maryland filers that made payments to [ ] Brands [ ]. And, as I said,
    they’re all blended together to come up with a factor that, again, it
    basically accounts for the same, it’s the same tax due as if you took
    each company separately, but it’s just combining them so it comes
    out to the same tax effect.
    ***
    [COMPTROLLER’S COUNSEL]: Okay.                 And where did the
    factors come from that were blended?
    [WOOD]: It’s, as I said, basically, it’s the same as taking each
    company by itself using that company’s Maryland
    apportionment factor, just as we did in SYL, Crown Delaware,
    Talbotts, Nordstrom, all of the cases that we’ve settled on. So
    it’s taking their Maryland factor and, again, it’s just a blending of
    each company.
    [COMPTROLLER’S COUNSEL]: Okay. And what was the
    objective of the Auditors in making this blended factor? What
    were they trying to do?
    [WOOD]: They were trying to get back the tax that we lost by
    the Maryland filer taking a deduction for the royalty expenses,
    just as we had in all those other cases.
    [COMPTROLLER’S COUNSEL]: Okay. Did this blended factor
    achieve that end?
    [WOOD]: Absolutely.
    (Emphasis added).
    In our view, TG § 10-402(d) and the teachings of Gore permit the Comptroller to
    use the Maryland apportionment factor of ConAgra and its subsidiaries to determine a
    blended apportionment factor. Accordingly, the Comptroller did not err or abuse its
    discretion in utilizing a blended apportionment factor to calculate the income tax owed by
    45
    Brands to Maryland on royalty payments received from ConAgra and its subsidiaries
    arising out of their business in Maryland.
    Lastly, Brands argues that the Comptroller’s assessment is unfair and violative of
    the U.S. Constitution because it does not reflect how income was generated for Brands,
    and the Comptroller “imposes tax on Brands based [solely] on its affiliates’ activities in
    Maryland.” Brands also contends that, even if Maryland allowed a blended apportionment
    factor to be used, as in this case, “the requirement of the United States Constitution that the
    apportionment factors used ‘actually reflect a reasonable sense of how income is generated’
    would not allow such result.” The Comptroller responds that it is Brands’s burden to
    demonstrate that the apportionment formula is unfair, and Brands has failed to cite anything
    in the record demonstrating that the apportionment formula used by the Comptroller is
    unfair. We agree with the Comptroller.
    When a company is engaging in a unitary business, as in the case sub judice, the
    company “bears the burden of demonstrating that the income it seeks to exclude from
    taxation was derived from unrelated business activity that constituted a discre[te] business
    enterprise.” 
    NCR, 313 Md. at 132
    ; see also 
    Gore, 437 Md. at 531
    . Brands has failed to
    direct this Court to any evidence demonstrating that the Comptroller’s assessment is unfair.
    Thus there was substantial evidence to support the Tax Court’s decision upholding the
    Comptroller’s income tax assessment against Brands.
    46
    IV.    Waiver of Interest19
    A. Background
    Under TG § 13-606, “[f]or reasonable cause, a tax collector may waive interest on
    unpaid tax.” In Frey v. Comptroller, 
    422 Md. 111
    , 184-85 (2011), cert. denied, 
    566 U.S. 905
    (2012), the Court of Appeals stated that the authority to abate interest vests not just in
    the Comptroller, but in the Tax Court, too. The Court explained that, when the Tax Court
    reviews the Comptroller’s decision declining to abate interest in an assessment, the court’s
    review “is deferential to the tax collector’s discretion[,]” and the court must consider
    whether “the [complaining] party has demonstrated with affirmative evidence that
    reasonable cause exists or that the tax collector’s decision was an obvious error.” 
    Id. at 187.
      Because the Tax Court in Frey did not consider whether Frey demonstrated
    reasonable cause to abate interest, the Court left open the question of what evidence was
    sufficient to demonstrate reasonable cause to waive interest. 
    Id. B. Tax
    Court’s Ruling
    Before the Tax Court, Brands requested that the court abate interest on the tax
    assessments. In its opinion, the court ruled:
    The final question for the [c]ourt’s determination is whether
    interest and penalties should be waived under Tax-General Article
    Sections 13-606 (waiver of interest) and 13-714 (waiver of
    penalties). In Frey v. Comptroller of the Treasury, 
    184 Md. App. 315
    , 421 (2009), the Court of Special Appeals referred to the
    reasonable cause exception set forth in the applicable statutes. The
    19
    When the Comptroller filed its cross-petition for judicial review in the circuit
    court, the Comptroller did not challenge the Tax Court’s ruling abating penalties assessed
    against Brands. Accordingly, the Tax Court’s abatement of penalties is not before us in
    this appeal.
    47
    [c]ourt finds that [Brands] has a reasonable basis for challenging
    the law and acted in good faith. There was no intention on the part
    of [Brands] to cause delay in the collecting of taxes and this [c]ourt
    notes that numerous taxpayers have challenged the Comptroller’s
    arguments. The [c]ourt disagrees with the Comptroller that the
    state of the law was clear to the taxpayer at the time of the
    assessments. To the contrary, the state of the law has evolved
    through various court decisions in SYL, Crown Cork & Seal[,] The
    Classic Chicago, Inc. v. Comptroller of the Treasury, 
    189 Md. App. 695
    (2010), Nordstrom, Inc. v. Comptroller of the Treasury, (Md.
    Tax Ct. Oct. 24, 2008) and Gore Enterprise Holdings.
    (Emphasis added). The court then ordered the abatement of all “interest after the date of
    filing this appeal in the Maryland Tax Court (February 23, 2009) until the date of this Order
    [February 24, 2015.]”
    The Comptroller filed a cross-petition for judicial review in the circuit court. The
    Comptroller argued that the Tax Court did not use the proper standard for abating interest
    and that at the very least, the court should not have abated interested accruing after the
    issuance of the Gore opinion, which was on March 24, 2014. Brands contended that the
    Tax Court properly abated all interest until the date of that court’s decision. The circuit
    court reversed the Tax Court’s abatement of interest from the date of the issuance of the
    Gore opinion, March 24, 2014, until the date of the Tax Court’s opinion in the instant case,
    February 24, 2015, a period of eleven months.20
    20
    In considering the abatement of interest, the circuit court wrote in its
    Memorandum Opinion: “Brands shall be responsible for any and all interest collected after
    the date of the issuance of the Gore decision on March 24, 2014.” The court’s Order,
    however, stated that “[f]or the reasons stated in the foregoing opinion, . . . ORDERED,
    that the decision of the Maryland Tax Court, regarding the abatement of interest, is hereby
    REVERSED.” (Emphasis in original). The Memorandum Opinion and the Order,
    therefore, appear to be inconsistent, but because we review the holding of the Tax Court,
    we need not resolve this uncertainty. See 
    Gore, 437 Md. at 503
    .
    48
    C. Challenges to the Waiver of Interest
    Brands argues that the Tax Court properly ruled that Brands had demonstrated
    reasonable cause to waive interest because “Brands had a reasonable basis to challenge the
    law and acted in good faith.” Brands points out that “[t]here is no question that the
    assessments turned on the application and analysis of case law,” and that the state of the
    case law was unclear during the tax years at issue “and even at the time of the assessment.”
    Brands also contends that it “presented ample evidence, including two days of testimony
    and thousands of pages of exhibits, supporting that it had [a] reasonable basis to challenge
    the law, and the assessment of interest.” Brands concludes that, given the broad discretion
    accorded to the Tax Court in determining “reasonable cause”, as well as a lack of clarity in
    the case law, “the Tax Court properly exercised its discretion in waiving interest.”
    The Comptroller counters that “[b]oth the language of TG § 13-606 and the
    exposition of that language in Frey require that abatement of interest be based on
    ‘reasonable cause’ supported by ‘affirmative evidence.’” The Comptroller argues that
    Brands failed to produce any affirmative evidence of reasonable cause, and that the Tax
    Court did not make any factual findings based on such evidence. The Comptroller further
    characterizes the Tax Court’s standard for “reasonable cause” as “an absence of bad faith
    in filing the petition of appeal.” According to the Comptroller, if abatement of interest can
    be satisfied by merely demonstrating good faith in the pursuit of litigation, then the
    “survival of statutory interest assessments will become the exception rather than the rule.”
    We disagree with the Comptroller.
    49
    In its opinion, the Tax Court expressly found that Brands had “a reasonable basis
    for challenging the law and acted in good faith.” Such finding clearly came from the
    extensive evidence adduced by Brands during the two-day trial before the Tax Court,
    coupled with the court’s accurate description of the state of the case law as an evolution
    “though various court decisions” over the period of 2003 to 2014. We disagree with the
    Comptroller’s characterization of the Tax Court’s “reasonable cause” standard as merely
    the absence of bad faith in pursuing the appeal to the Tax Court. Given that the legality of
    the tax assessments at issue turned on the application of case law, the Tax Court properly
    focused its “reasonable cause” analysis on the state of that case law and its applicability to
    Brands.
    The Tax General Article does not define reasonable cause, and as 
    explained supra
    ,
    we give “great weight” to “[t]he legal conclusions of an administrative agency that are
    premised upon an interpretation of the statutes that the agency administers.” 
    Gore, 437 Md. at 505
    (internal quotation marks omitted). In our view, there is nothing in the statute
    or case law that precludes the Tax Court from finding reasonable cause for abatement of
    interest from the uncertainty in the state of the case law when applied to the circumstances
    of a particular taxpayer. Accordingly, we shall uphold the Tax Court’s ruling to abate the
    interest accrued from the date of the filing of the appeal to the Tax Court, February 23,
    2009, to the date of the court’s Memorandum of Grounds for Decision, February 24, 2015.
