    INTRODUCTION
    These appeals arise out of related taxpayer suits brought
    by appellant Michael D. Myers under Code of Civil Procedure
    section 526a. Myers seeks to compel the California State Board of
    Equalization, the Insurance Commissioner of the State of
    California, and the Controller of the State of California to collect
    the gross premium tax (GPT) imposed by article XIII, section 28
    of the California Constitution from certain health care service
    plans (HCSPs), which are regulated by the Department of
    Managed Health Care (DMHC) under a different regulatory
    scheme than insurers.
    In Myers v. Board of Equalization (2015) 
    240 Cal.App.4th 722
     (Myers I), a different panel of this Division rejected the
    argument that the regulatory status of HCSPs determines
    whether they are subject to the GPT, and adopted a standard for
    deciding whether HCSPs are insurers for taxation purposes that
    requires balancing the indemnity aspects of the business against
    the direct service aspects and determining whether indemnity
    constitutes a significant financial proportion of the business. Real
    Parties in Interest and respondents Blue Cross of California dba
    Anthem Blue Cross (Blue Cross), California Physicians’ Service
    dba Blue Shield of California (Blue Shield), Health Net of
    California, Inc. (Health Net), and Kaiser Foundation Health
    Plan, Inc. (Kaiser) (together, Real Parties in Interest) moved for
    summary judgment, arguing that the undisputed evidence
    demonstrated that they were not insurers where less than 10
    percent of the expenses incurred for medical services under their
    plans during the relevant periods constituted indemnity under
    the Myers I standard. The trial court agreed and granted
    summary judgment in their favor.
    3
    Myers contends that the trial court incorrectly understood
    the meaning of indemnity under the Myers I standard and that it
    should have applied a different test to determine whether Real
    Parties in Interest are insurers. Myers further contends that the
    court erred in excluding portions of expert declarations and other
    evidence he submitted in opposition to summary judgment. We
    conclude that we are bound by the standard adopted in Myers I,
    that the trial court did not err in its application of this standard
    to the undisputed facts, and that the court did not abuse its
    discretion in excluding certain evidence submitted by Myers. We
    therefore affirm.
    FACTS AND PROCEDURAL BACKGROUND
    1.    Taxation of Insurers in California
    Article XIII, section 28 of the California Constitution
    imposes a tax of 2.35 percent on the amount of gross premiums
    received each year by “each insurer doing business in this state.”
    (Cal. Const., art. XIII, § 28, subds. (b), (d).) The Constitution
    defines “insurers” as including “insurance companies or
    associations and reciprocal or interinsurance exchanges together
    with their corporate or other attorneys in fact considered as a
    single unit, and the State Compensation Insurance Fund.” (Id.,
    subd. (a).)1
    The GPT is imposed on insurers “in lieu of all other taxes
    and licenses, state, county, and municipal, upon such insurers
    1 Article XIII, section 28 was preceded by former article XIII, chapter
    14 of the Constitution, which was adopted in 1910 and provided that
    “[e]very insurance company or association doing business in this state ”
    would be subject to an exclusive GPT.
    4
    and their property,” with limited exceptions. (Cal. Const., art.
    XIII, § 28, subd. (f); see also Mutual Life Ins. Co. v. City of Los
    Angeles (1990) 
    50 Cal.3d 402
    , 408 (Mutual Life Ins. Co.).) All
    other businesses, except for banks and financial corporations, are
    subject to a corporate franchise tax which is calculated on the
    basis of the business’s net income. (Rev. & Tax. Code, § 23151,
    subds. (a), (f).)
    According to a July 2008 report by the Legislative Analyst’s
    Office, “ ‘[t]he economics of the insurance industry is a key reason
    for the special treatment of insurance companies’ with respect to
    taxation in California. The report explains the rationale as
    follows: ‘Most [corporate franchise tax] taxpayers calculate their
    income by subtracting costs incurred in the production of a good
    or service from the revenues received from their sale. Insurance
    companies, by contrast, collect their revenues up front [in the
    form of premiums], then make payments to policyholders based
    on contingent events that occur many months or years later.
    Thus, it can be difficult to “match up” revenues to related
    expenses. In an income tax framework, insurers ideally would be
    allowed to deduct the current value of all future obligations
    (claims) covered by the insurance policies they have written when
    calculating their taxable income for a given year. [However,]
    [b]ecause the actual amount of these obligations is uncertain, as
    are the amount of investment earnings on accumulated
    premiums received during the intervening period, an accurate
    determination of the theoretically appropriate amount of taxable
    income proves very difficult to achieve in practice.’ ‘For this
    reason,’ the Legislative Analyst’s Office report concludes, ‘a
    [gross] premiums tax was adopted.’ ” (Myers I, supra, 240
    5
    Cal.App.4th at p. 736, quoting Legis. Analyst, Investment Income
    and the Insurance Gross Premiums Tax (July 2008) p. 3.)
    2.    Legislation and Case Law Concerning the Oversight
    and Taxation of HCSPs
    2.1.   The Origins of HCSPs in California
    In 1939, the Legislature passed a bill creating section 593a
    of the Civil Code, which authorized the formation of health
    service corporations. (California Physicians’ Service v. Garrison
    (1946) 
    28 Cal.2d 790
    , 792–793, 802, fn. 1 (Garrison).)
    In Garrison, supra, 
    28 Cal.2d 790
    , the Supreme Court held
    that California Physicians’ Service (CPS), which served as an
    agent to secure medical care for low-income individuals in
    exchange for the payment of monthly membership dues through
    an employer or professional organization, was not engaged in the
    business of insurance under California law. CPS’s contract with
    employers and professional organizations provided that the
    amounts paid by the employers or professional group “are
    accepted by [CPS] and its professional members as full payment
    and compensation for all medical and surgical services rendered
    during the immediately preceding dues period, and they and each
    of them agree to perform the services herein included, without
    other, further or additional charge of any kind whatsoever to
    those beneficiary members . . . .” (Id. at p. 796.) The Insurance
    Commissioner argued that section 593a was invalid, that “[a]ll of
    the elements of insurance are present in [CPS’s] plan,” and that
    “[t]here is no real distinction between service and insurance, and
    by its contracts the corporation has obligated itself to furnish
    medical care.” (Id. at pp. 798–799.) CPS argued that it was “not
    engaged in the insurance business but is rendering personal
    6
    service, as distinguished from indemnity, compensation for which
    is limited to the resources of a pooled fund; that the professional
    members, not the Service, assume any and all risk; and that it is
    actually a producer-consumer cooperative.” (Id. at p. 799.)
    The Supreme Court observed that “it is a matter of common
    knowledge that there is great social need for adequate medical
    benefits at a cost which the average wage earner can afford to
    pay,” and that “the Legislature, by enacting section 593a of the
    Civil Code, expressly authorized the organization of corporations
    such as [CPS]. By this enactment, the state’s social policy in
    regard to the corporate practice of medicine, to the limited extent
    specified, has been determined and the courts are bound
    thereby.” (Garrison, supra, 28 Cal.2d at pp. 801–802, fn. omitted.)
    The court stated that “ ‘[t]he question of classification is generally
    one for the legislative power, to be determined by it in the light of
    its knowledge of all the circumstances and requirements, and its
    discretion will not be overthrown unless it is palpably arbitrary.
    [Citation.]’ ” (Id. at p. 802.) It further observed that “the
    Legislature has defined insurance as ‘a contract whereby one
    undertakes to indemnify another against loss, damage, or
    liability arising from a contingent or unknown event’ (Ins. Code,
    § 22; Civ. Code, § 2527[]),” and “ ‘insurance generally may be
    defined as an agreement by which one person for a consideration
    promises to pay money or its equivalent, or to perform some act of
    value, to another on the destruction, death, loss, or injury of
    someone or something by specified perils.’ [Citation.]” (Id. at
    pp. 803–804.) The court concluded that CPS was not an insurer
    because it did not assume risk; rather, because the physicians
    received pro rata payments per member, “the amount of
    compensation of the professional members is variable and may be
    7
    high or low, depending upon the incidence of sickness and the
    number of beneficiary members paying dues. Stated in terms of
    insurance, all risk is assumed by the physicians, not by the
    corporation.” (Id. at pp. 804–805.)
    The court stated that a further, “more compelling reason
    for holding that the Service is not engaged in the insurance
    business” was that “[a]bsence or presence of assumption of risk or
    peril is not the sole test to be applied in determining its status.
    The question, more broadly, is whether looking at the plan of
    operation as a whole, ‘service’ rather than ‘indemnity’ is its
    principal object and purpose. [Citations.]” (Garrison, supra, 28
    Cal.2d at p. 809.) The Garrison court explained that the objects
    and purposes of CPS “have a wide scope in the field of social
    service.” (Ibid.) It therefore concluded that CPS was not engaged
    in the business of insurance within the meaning of the regulatory
    statutes. (Id. at p. 811.)
    2.2.   The Knox-Mills Plan Act
    In 1965, the Legislature enacted the Knox-Mills Plan Act
    (Knox-Mills Act), which specifically governed health plans. Under
    the Knox-Mills Act, health plans were required to register with
    the Attorney General and to meet minimum tangible net equity
    requirements. In addition, the Attorney General was empowered
    to enforce prohibitions against fraudulent advertising. (Sen. Com.
    on Health and Welfare, Analysis of Assem. Bill No. 138 (Knox)
    (1975–1976 Reg. Sess.) as amended June 27, 1975, p. 1.)
    In People ex rel. Roddis v. California Mut. Assn. (1968) 
    68 Cal.2d 677
    , 679 (Roddis), the Supreme Court considered whether
    California Mutual Association (CMA) was an insurer subject to
    the supervision of the Insurance Commissioner or an HCSP
    pursuant to the Knox-Mills Act and thus subject to the
    8
    supervision of the Attorney General. CMA’s stated purpose was
    to make payments in limited amounts for medical and hospital
    services rendered to its members using funds derived from
    periodic dues. (Id. at p. 678.) At the start of trial, CMA had
    contracts with 17 physicians who agreed to render services to
    members and to look exclusively to CMA for the payment of the
    scheduled fee. (Id. at pp. 678–679.) It was also stipulated that a
    majority of CMA’s members were treated by physicians affiliated
    with the San Bernardino Foundation for Medical Care and the
    Riverside Foundation. (Id. at p. 679.) CMA did not have contracts
    with the individual affiliated doctors at either foundation. (Ibid.)
    By the end of trial, CMA had terminated its contract with the
    San Bernardino foundation and had contracted with 38
    physicians who agreed to render services to CMA’s members and
    to look exclusively to CMA for payment of the scheduled fee.
    (Ibid.) CMA also had about seven physicians who agreed to serve
    members but did not restrict themselves as to the source of
    payment. (Ibid.) CMA encouraged its members to use the services
    of physicians with whom it had contracts, but also paid the bills
    of physicians independently chosen by a member in areas where
    it did not have contracts for medical services. (Ibid.)
    The Supreme Court observed that the Knox-Mills Act
    “permits a health care service plan to ‘reimburse’ a member and
    thus indicates that service plans may include some indemnity
    features” but also excludes “ ‘insurer’ from the definition of a
    ‘health care service plan[,]’ ” thus “evinc[ing] an intention to limit
    the extent of indemnity features permissible.” (Roddis, supra, 68
    Cal.2d at p. 681.) It fell to the court to determine the limit of
    indemnity features permissible for an HCSP. (Ibid.) The court,
    citing Garrison, observed that there are two policy considerations
    9
    that must be considered in determining the nature of a plan:
    “Where indemnity features are present, the member bears the
    risk of personal liability for medical services. This is the
    insurance risk which can be protected against by financial
    reserves to assure that the member will receive the benefits for
    which he has paid. On the other hand, there is a strong social
    policy to encourage the services which health plans provide the
    public.” (Id. at p. 682.) The court concluded “that where
    indemnity is a significant financial proportion of the business,
    the organization must be classified as an ‘insurer’ for the
    purposes of the Knox-Mills Plan Act.” (Id. at p. 683.) “[T]his
    determination involves balancing the indemnity aspects against
    the direct service aspects of the business, but only in the context
    of the plan as a whole can it be determined whether the
    indemnity feature is so significant as to warrant imposing the
    Insurance Code financial reserve requirements.” (Ibid.)
    The court observed that “[a]lthough CMA’s contracts with
    the 38 physicians provide for direct service without indemnity,
    the remainder of the plan is one of insurance[,]” as members were
    liable for services procured from the Riverside foundation, from
    the seven physicians who did not limit themselves exclusively to
    payments from CMA, and from physicians with whom CMA did
    not have contracts. (Roddis, supra, 68 Cal.2d at p. 683.) The court
    observed that it was unclear from the record “what proportion of
    CMA’s members is treated by the 38 physicians” and thus “to
    what extent indemnity features are still present” and therefore
    instructed the court on retrial “to determine as of that time in
    accordance with the views expressed in this opinion the status of
    CMA as a health care service plan or as an insurer.” (Id. at
    pp. 683–684.)
    10
    2.3.   The Knox-Keene Health Care Service Plan Act of
    1975
    The Knox-Mills Act was repealed in 1975, effective July 1,
    1976. (Stats. 1975, ch. 941, § 1, p. 2070.) In 1975, the Legislature
    adopted the Knox-Keene Health Care Service Plan Act of 1975
    (Knox-Keene Act) with the express intent and purpose to
    “promote the delivery and the quality of health and medical care
    to the people of the State of California who enroll in, or subscribe
    for the services rendered by, a [HCSP] by accomplishing all of the
    following: [¶] (a) Ensuring the continued role of the professional
    as the determiner of the patient’s health needs. . . . [¶]
    (b) Ensuring that subscribers and enrollees are educated and
    informed of the benefits and services available. . . . [¶]
    (c) Prosecuting malefactors who make fraudulent solicitations or
    who use deceptive methods. . . . [¶] (d) Helping to ensure the best
    possible health care for the public at the lowest possible cost by
    transferring the financial risk of health care from patients to
    providers. [¶] (e) Promoting effective representation of the
    interests of subscribers and enrollees. [¶] (f) Ensuring the
    financial stability thereof by means of proper regulatory
    procedures. [¶] (g) Ensuring that subscribers and enrollees
    receive available and accessible health and medical services
    rendered in a manner providing continuity of care. [¶]
    (h) Ensuring that subscribers and enrollees have their grievances
    expeditiously and thoroughly reviewed by the [DMHC].” (Health
    & Saf. Code, § 1342.)
    In relevant part, the Knox-Keene Act defines HCSPs that
    are subject to the law’s regulations as “[a]ny person who
    undertakes to arrange for the provision of health care services to
    subscribers or enrollees, or to pay for or to reimburse any part of
    11
    the cost for those services, in return for a prepaid or periodic
    charge paid by or on behalf of the subscribers or enrollees.”
    (Health & Saf. Code, § 1345, subd. (f)(1).)2 HCSPs as defined in
    and regulated by the Knox-Keene Act are under the jurisdiction
    of the DMHC. (Id., § 1341.) Though such entities are authorized
    to provide direct payment or reimbursement coverage for their
    enrollees’ medical expenses, HCSPs are statutorily exempted
    from the Department of Insurance’s jurisdiction and are not
    subject to the Insurance Code’s regulations. (Ins. Code, § 740,
    subd. (g).) This exemption extends to HCSPs offering fee-for-
    service coverage through a preferred provider organization plan.
    (Id., § 742, subd. (a).)
    Under the Knox-Keene Act, HCSPs must “establish and
    maintain provider networks, policies, procedures, and quality
    assurance monitoring systems and processes sufficient to ensure
    compliance with this clinical appropriateness standard.” (Health
    & Saf. Code, § 1367.03, subd. (a)(1).) They must also ensure a
    legally prescribed ratio of members to primary care physicians
    (id., § 1375.9; Cal. Code Regs., tit. 28, § 1300.51, subd. (d)(H)(i))
    and comply with requirements concerning the timely availability
    of appointments. (Cal. Code Regs., tit. 28, § 1300.67.2.2,
    subd. (c).) HCSPs must also establish procedures to “continuously
    2 Originally, the Knox-Keene Act defined an HCSP as “any person who
    undertakes to arrange for the provision of health care services, to
    subscribers or enrollees, or to pay for or reimburse any part of the cost
    for such services in return for a prepaid or periodic charge paid by or
    on behalf of such subscribers or enrollees, and who does not
    substantially indemnify subscribers or enrollees for the cost of provided
    services.” (Former Health & Saf. Code, § 1345, subd. (f), italics added.)
    In 1980, the Legislature removed the reference to indemnity from the
    definition. (Stats. 1980, ch. 628, § 2, p. 1716.)
    12
    review[] the quality of care, performance of medical personnel,
    utilization of services and facilities, and costs” (Health & Saf.
    Code, § 1370) and must establish and maintain a system,
    approved by DMHC, that allows members to submit their
    grievances to the plan. (Id., § 1368, subd. (a); Cal. Code Regs.,
    tit. 28, § 1300.68.)
    Because HCSPs include, by definition, entities that agree to
    “pay for or to reimburse” enrollees for the cost of medical services
    in exchange for a “prepaid or periodic charge” (Health & Saf.
    Code, § 1345, subd. (f)(1)), the Knox-Keene Act includes
    capitalization requirements and vests financial oversight
    authority in the DMHC. (Id., §§ 1376, 1377, 1399, subd. (c).)
    California law further requires that every contract between a
    plan and a health care services provider must state that “the
    subscriber or enrollee shall not be liable to the provider for any
    sums owed by the plan.” (Id., § 1379, subd. (a).) Moreover, even if
    the contract fails to include this provision, the statute provides
    that “the contracting provider shall not collect or attempt to
    collect from the subscriber or enrollee sums owed by the plan.”
    (Id., subd. (b).) Thus, “[t]he clear import of section 1379 is to
    protect patients with health care service plan coverage from any
    collection attempts by providers of such medical care as
    emergency room services.” (Dameron Hospital Assn. v. AAA
    Northern California, Nevada & Utah Ins. Exchange (2014) 
    229 Cal.App.4th 549
    , 563.)
    2.4.   Recent Legislation Concerning the Taxation of
    HCSPs
    In 2016, new legislation—Senate Bill No. X2-2—was
    enacted in response to positions taken by the federal government
    regarding the conditions necessary to receive federal monies
    13
    funding the Medi-Cal program. The purpose of Senate Bill No.
    X2-2 was to “[r]eform[] the existing managed care organization
    (MCO) provider tax that is only paid by Medi-Cal managed care
    plans (MCPs) and replace[] it with a tax that would be assessed
    on health care service plans licensed by the [DMHC], and/or
    managed care plans contracted with the Department of Health
    Care Services (DHCS) to provide services to Medi-Cal
    beneficiaries, unless exempted, from July 1, 2016 to July 1,
    2019.” (Sen. Bill No. X2-2, Proposed Conference Report No. 1,
    Feb. 22, 2016, p. 1.) The bill thus imposed an MCO tax on many
    HCSPs for the first time. Some health plans, including those of
    some of the Real Parties in Interest, also operate an admitted
    health insurer. As to those entities, the new statute temporarily
    reduced the GPT to 0 percent. (Stats. 2015–2016, 2nd Ex. Sess.,
    ch. 2, p. 6030.)
    Assembly Bill No. 115, which became effective July 1, 2019,
    “establish[ed] a managed care organization provider tax, with
    substantially similar provisions [to the 2016 MCO tax], that
    would become effective and operative on the effective date of the
    federal approval necessary for receipt of federal financial
    participation, as specified[]” and “specif[ied] the applicable tax
    amounts for each taxing tier for the 2019–20, 2020–21, and 2021–
    22, fiscal years, and the first 6 months of the 2022–23 fiscal
    year.” (Stats. 2019–2020, ch. 348, p. 3232.) This bill, like the prior
    MCO tax, was intended to comply with federal requirements that
    allow states to receive “federal financial participation for
    expenditures using health care-related taxes, as long as the taxes
    are broad-based, uniformly imposed, and contain no hold-
    harmless provision.” (Sen. Rules Com., Off. of Sen. Floor
    14
    Analyses, 3d reading analysis of Assem. Bill No. 115 (2019–2020
    Reg. Sess.) as amended Aug. 29, 2019, p. 1.)
    3.    Real Parties in Interest
    3.1.   Blue Cross
    In the mid-to-late 1980’s, Blue Cross operated as a
    nonprofit hospital service plan and was facing financial
    difficulties. To address Blue Cross’s dire situation, to help ensure
    its survival, and to prevent adverse impacts on consumers and
    the California health benefits market, the Legislature enacted
    Senate Bill No. 785. (Stats. 1990, ch. 1043.) Senate Bill No. 785
    essentially required Blue Cross to transition from being a
    nonprofit hospital service plan under Chapter 11A of the
    Insurance Code to being a health care service plan regulated by
    the Department of Corporations (DOC) under the Knox-Keene
    Health Care Service Plan Act. Blue Cross undertook a number of
    changes required by the DOC and is now a Knox-Keene Act-
    licensed HCSP regulated by the DMHC.3
    Blue Cross offers its members access to health maintenance
    organization (HMO) and preferred provider organization (PPO)
    health plans. Under HMO and PPO plans, members have access
    to a network of medical providers, hospitals, and other facilities
    that have contracted with Blue Cross to provide medical services
    to Blue Cross members at agreed upon rates. For Blue Cross’s
    commercial HMO and PPO plans, groups and members pay Blue
    Cross a fixed periodic fee for coverage, called the “premium,”
    which does not change during the coverage period based on the
    3The regulation of HCSPs has transferred from the DOC to the
    DMHC.
    15
    amount of medical services a member uses. Under Blue Cross’s
    HMO and PPO plans, the member also may be responsible for a
    portion of the costs of the medical care they receive, generally in
    the form of deductibles,4 copayments (or “co-pays”),5 or
    coinsurance,6 which are sometimes called the “cost share.”
    For both HMO and PPO plans, Blue Cross’s in-network
    providers have agreed to accept Blue Cross’s payment at the rate
    agreed upon in their contract with Blue Cross as payment-in-full
    for the covered services they render to Blue Cross members. Blue
    Cross’s in-network providers are contractually prohibited from
    billing Blue Cross members for any difference between their
    contractually agreed upon rate and their usual charges for the
    covered services they provide to Blue Cross members (a practice
    known as “balance billing”). For the years 2005 through 2016,
    Blue Cross’s HMO and PPO plans have included the following (or
    4 A deductible is an amount that a particular plan may require the
    member to pay before Blue Cross has any obligation to cover medical
    services for that member (e.g., if the plan has a $500 annual
    deductible, the member must pay the first $500 of medical services she
    receives during the coverage year, and Blue Cross would not cover the
    first $500 in medical services). Blue Shield’s, Kaiser’s, and Health
    Net’s member contracts contain substantially similar definitions.
    5A copayment is an amount the member pays directly to the medical
    provider at the time medical services are rendered, and this amount is
    not covered by Blue Cross. Blue Shield’s, Kaiser’s, and Health Net’s
    member contracts contain substantially similar definitions.
    6A plan may require the member to pay a portion of the amount Blue
    Cross has negotiated as the price for a particular service, which is
    sometimes called “coinsurance” (e.g., a plan may require Blue Cross to
    pay 80 percent of the allowed amount for any covered services, while
    the member is obligated to pay 20 percent of the cost of those services).
    Kaiser’s member contract contains a substantially similar definition.
    16
    substantially similar) language: “In accordance with California
    law, Members will not be required to pay any Participating
    Provider for amounts owed to that provider by Anthem (other
    than Copayment/Coinsurance and Deductibles) even in the
    unlikely event that Anthem fails to pay the provider. Members
    are liable, however, to pay Non-Participating Providers for any
    amounts not paid to them by Anthem.”
    For the years 2005 through 2016, Blue Cross’s agreements
    with participating physicians, hospitals, and medical facilities
    stated that, except for copayments, coinsurance, and deductible
    amounts required by the applicable agreement, the physicians,
    hospitals, and medical facilities would not invoice or balance bill
    a member for any difference between the billed charges and the
    reimbursement paid by Blue Cross for services provided to the
    member. For the same period, Blue Cross’s agreements with
    participating physician associations and medical groups required
    that the physician association or medical group accept a monthly
    capitation payment from Blue Cross as payment in full for
    services provided or arranged and not to invoice, balance bill or
    otherwise seek payments or compensation from members for
    “Covered Medical Services.” Similarly, Blue Cross’s agreements
    with participating hospitals and medical facilities during that
    period included language stating that the hospital or facility
    would look solely to Blue Cross for payment, subject to limited
    exceptions, and cannot seek compensation from any member.
    Blue Cross’s PPO plans between 2005 and 2016 included
    language generally providing that, for covered out-of-network
    services, Blue Cross would cover (i) an amount that is “customary
    and reasonable” for medical providers in the same geographical
    area to accept for such services, (ii) an amount determined with
    17
    reference to a separate payment schedule (e.g., the Medicare fee
    schedule), (iii) an amount based on the provider’s billed charges,
    or (iv) a specifically negotiated amount. For the same period,
    Blue Cross’s PPO plans have included the following language, or
    substantially similar language: “When you use an Out-of-
    Network Provider, You may have to pay the difference between
    the Out-of-Network Provider’s billed charge and the Maximum
    Allowed Amount in addition to any Coinsurance, Copayments,
    Deductibles and non-covered charges. This amount can be
    substantial.” Blue Cross’s PPO plans generally cover a lower
    percentage of the covered amount for out-of-network services
    than the percentage they cover for in-network services.
    The annual percentage of Blue Cross’s reported in-network
    medical expenses as compared to its total medical expenses for its
    commercial plans for the years 2005 to 2016, as reported by Blue
    Cross to the DMHC, ranged from approximately 92.1 percent to
    96.8 percent. During that period, Blue Cross reported aggregate
    expenses for out-of-network claims that were 5.8 percent of its
    total claims expenses, and aggregate expenses for in-network
    claims that were 94.2 percent of its total claims expenses.
    Between 2005 and 2016, Blue Cross paid between
    approximately 87.7 percent and 90.4 percent of claims expenses
    incurred for medical services provided to its members within the
    same calendar year as the year the services were rendered. For
    each year during this period, Blue Cross paid over 99 percent of
    claims expenses incurred for medical services provided to its
    members by the end of August the following year.
    3.2.   Blue Shield
    Blue Shield is an HCSP regulated by the DMHC under the
    Knox-Keene Act. Blue Shield arranges and pays for medical care
    18
    to its members through a variety of managed health care
    products, including HMO and PPO plans. In addition to paying
    and processing member claims, Blue Shield engages in the
    provision of other health care services to its members and spends
    more than $100 million annually on service functions other than
    processing and paying claims. Examples include developing and
    maintaining networks of health care providers, credentialing
    contracted providers, reviewing quality of care and performance
    of medical personnel, and ensuring appropriate referrals to
    specialists.
    Blue Shield contracts with providers who agree in advance
    to render services to Blue Shield PPO and HMO plan members at
    contracted rates and not to seek payment from the members,
    other than contractually required member cost share amounts
    (i.e., deductibles, copayments, and coinsurance). Blue Shield’s
    HMO and PPO contracts with members also reflect the
    prohibition on member financial liability to contracted providers.
    Some non-contracted providers are also prohibited from
    attempting to collect from plan members, including non-
    contracted providers of emergency services, non-contracted
    providers who provide services authorized by the plan that
    cannot be rendered in-network, and continuity of care services
    when a contracted provider becomes a non-contracted provider.
    In the case of HMO plans, members must use contracted
    providers for nearly all care for that care to be covered under the
    plan. HMO members are required to choose an in-network
    primary care physician upon enrollment, and the primary care
    physician is responsible for coordinating the medical services
    provided to the HMO member. Services from non-contracted
    providers are not covered for HMO members except in limited
    19
    circumstances, such as emergencies and instances where a
    service or specialist is not available within the contracted
    network. HMO members typically are responsible for only a
    deductible and/or a copayment for services obtained within their
    network, and Blue Shield or the contracted medical group is
    responsible for the remainder.
    PPOs offer medical care through a network of providers
    who have contracted with Blue Shield to provide services at
    predetermined rates. Although PPO members, unlike HMO
    members, may choose to obtain services from non-contracted (out-
    of-network) providers, PPO plans incentivize the use of
    contracted providers by setting lower member deductibles,
    copayments, and/or coinsurance rates for services from contracted
    providers, and protecting members from the difference between
    what Blue Shield pays and the balance of the contracted
    providers’ billed rates. PPO members may also be responsible for
    deductibles, copayments, or coinsurance.
    Between 2005 and June 2016, Blue Shield’s expenditures to
    contracted providers, as reported to the DMHC on quarterly and
    year-end financial statements, ranged from 94 percent to 97
    percent, averaging 96 percent, and expenditures to non-
    contracted providers averaged 4 percent.
    3.3.   Kaiser
    Kaiser is an HCSP licensed under the Knox-Keene Act and
    regulated by the DMHC. Kaiser provides medical and hospital
    services to its members through a nonprofit organization, Kaiser
    Foundation Hospitals, Inc. (KFH), and two medical groups, The
    Permanente Medical Group, Inc. and Southern California
    Permanente Medical Group (together, the Permanente Medical
    Groups). Collectively, these separate legal entities operate under
    20
    the trade name “Kaiser Permanente.” KFH and the Permanente
    Medical Groups employ tens of thousands of physicians and
    nurses and operate dozens of hospitals and hundreds of other
    medical facilities. Kaiser contracts with KFH to directly provide
    hospital facilities and related hospital services to Kaiser’s
    members. KFH owns all the Kaiser hospitals in California, and
    Kaiser and KFH own or lease all the medical offices used by
    Kaiser Permanente clinicians to provide care to Kaiser members
    in California. To the extent community hospital and related
    services are needed to supplement Kaiser’s hospital services,
    KFH arranges with community hospitals and providers for such
    services. Kaiser and KFH are separate corporations but are
    historically and operationally intertwined, with overlapping
    boards of directors and top executives in common.
    There are two Hospital Services Agreements between
    Kaiser and KFH, one applicable to its Northern California service
    area and one applicable to its Southern California service area.
    The Permanente Medical Groups are responsible for directly
    providing or arranging all the professional medical services that
    Kaiser’s California members are entitled to under their
    membership agreement with Kaiser. The Permanente Medical
    Groups do not contract to provide care to members of other health
    care service plans and do not contract with indemnity health
    insurers. Since 1990, Kaiser’s contracts with the Southern
    California Permanente Medical Group have contained exclusivity
    provisions, and from 2006 to 2016, Kaiser’s contracts with The
    Permanente Medical Group, Inc. have contained exclusivity
    provisions.
    Kaiser and KFH report their financial results on a
    combined basis. Until 2016, Kaiser directly reimbursed KFH’s
    21
    net operating expenses as the primary form of compensation for
    the provision of hospital services to Kaiser members. In addition,
    Kaiser and KFH shared a portion of any combined annual net
    operating revenue gain or loss in proportion to the parties’
    respective share of financed assets. Beginning in 2016, the
    payment structure was modified in part so that, in addition to
    continuing to reimburse certain expenses of KFH, Kaiser began
    to also pay KFH using a combination of per capita and other
    payments.
    Kaiser does not sell contracts that allow members to seek
    covered health care services from any provider or hospital of their
    choice, nor does Kaiser, with limited exceptions, promise to
    reimburse members for care they receive outside of Kaiser
    Permanente. Every Kaiser Evidence of Coverage document (EOC)
    issued in California between 2005 and 2016 contained the
    following (or substantially similar) language: “Kaiser
    Permanente provides Services directly to our Members through
    an integrated medical care program. Health Plan, Plan Hospitals,
    and the Medical Group work together to provide our Members
    with quality care. Our medical care program gives you access to
    all of the covered Services you may need, such as routine care
    with your own personal Plan Physician, hospital care, laboratory
    and pharmacy Services, Emergency Services, Urgent Care, and
    other benefits described in this Evidence of Coverage. Plus, our
    health education programs offer you great ways to protect and
    improve health.” Further, every Kaiser EOC sold in California
    between 2005 and 2016 states: “As a Member, you are selecting
    our medical care program to provide your health care. You must
    receive all covered care from Plan Providers inside our Service
    Area, except as described in the sections below for the following
    22
    Services[,]” including “ ‘authorized referrals,’ ‘emergency
    ambulance Services,’ ‘Emergency Services, Post -Stabilization
    Care, and Out-of-Area Urgent Care,’ and ‘Hospice Care.’ ” Every
    Kaiser EOC sold in California between 2005 and 2016 also
    stated: “Our contracts with Plan Providers provide that you are
    not liable for any amounts we owe.” However, Kaiser members
    are responsible for copayment, coinsurance, and deductible
    amounts when they seek medical care from KFH and the
    Permanente Medical Groups.
    The EOCs sold in California between 2005 and 2016
    further stated: “If you receive Emergency Services, Post-
    Stabilization Care, or Out-of-Area Urgent Care from a Non-Plan
    Provider as described in this ‘Emergency Services and Urgent
    Care’ section, or emergency ambulance Services described under
    ‘Ambulance Services’ in the ‘Benefits and Your Cost Share’
    section, you are not responsible for any amounts beyond your
    Cost Share for covered Emergency Services. However, if the
    provider does not agree to bill us, you may have to pay for the
    Services and file a claim for reimbursement. Also, you may be
    required to pay and file a claim for any Services prescribed by a
    Non-Plan Provider as part of covered Emergency Services, Post-
    Stabilization Care, and Out-of-Area Urgent Care even if you
    receive the services from a Plan Provider, such as a Plan
    Pharmacy.”
    Every Kaiser EOC in California between 2005 and 2016
    required the member or their employer to prepay premiums on a
    periodic basis. Thus, at the time that a service was rendered, the
    member’s financial responsibility for covered services was limited
    to the member’s cost share (including copayments).
    23
    The relevant contracts between Kaiser and The
    Permanente Medical Group, Inc., Southern California
    Permanente Medical Group and KFH, respectively, have member
    non-liability provisions, as do Kaiser’s contracts with providers
    outside of Kaiser Permanente.
    Between 2007 and 2016, measured by dollars,
    approximately 1 to 4 percent of Kaiser’s healthcare expenses
    were paid to noncontracting providers or directly reimbursed to
    members. The portion of expenses consisting of payments to non-
    contracted providers or reimbursements to members mainly
    consists of situations in which Kaiser has no control over what
    provider a member visits, such as emergency room treatment
    which Kaiser is required by law to cover regardless of whether it
    is contracted with the emergency provider.
    For the years 2007 through 2014, measured by discrete
    visits or consultations, approximately 95 percent of the covered
    health services provided to Kaiser members were rendered by
    Kaiser Permanente providers (i.e., Kaiser Foundation Hospitals,
    Inc., The Permanente Medical Group, Inc., and the Southern
    California Permanente Medical Group). In 2015, measured by
    discrete visits or consultations, approximately 93.3 percent of the
    covered health services provided to Kaiser members were
    rendered by Kaiser Permanente providers, while only
    approximately 6.7 percent of services were rendered by
    contracted or non-contracted providers outside Kaiser
    Permanente. In 2016, measured by discrete visits or
    consultations, approximately 94.7 percent of the covered health
    services provided to Kaiser members were rendered by Kaiser
    Permanente providers, while only approximately 5.3 percent of
    24
    services were rendered by contracted or non-contracted providers
    outside Kaiser Permanente.
    Kaiser’s contracts with the Permanente Medical Groups
    provide for compensation to be paid largely on a prepayment
    basis, in which the amount of compensation is determined in
    advance (based on factors such as number of members) and not
    based on the amount of services actually provided to members.
    The principal form of such prepayment is capitation. Kaiser’s
    contracts with the Permanente Medical Groups each require
    Kaiser to make per capita (capitated)7 payments based on the
    number of members served by the medical group, regardless how
    many members actually seek services during a given period and
    regardless of the amount of services used by the members.
    Capitated payments thus represent a substantial majority of the
    payments made by Kaiser to the two medical groups.
    3.4.   Health Net
    Health Net is a Knox-Keene Act licensed HCSP. Health
    Net offers access to HMO plans to its members, as well as Point
    of Service, Medicare, and Medi-Cal plans. ) Health Net does not
    offer PPO plans or traditional health and accident insurance
    plans to its members.
    7“ ‘ “[C]apitated basis” ’ is defined by regulation to mean ‘fixed per
    member per month payment or percentage of premium payment
    wherein the provider assumes the full risk for the cost of contracted
    services without regard to the type, value or frequency of services
    provided.’ ” (Centinela Freeman Emergency Medical Associates v.
    Health Net of California, Inc. (2016) 
    1 Cal.5th 994
    , 1004, fn. 8, quoting
    Cal. Code Regs., tit. 28, § 1300.76, subd. (d).) In contrast, non-capitated
    payments include fee-for-service payments.
    25
    When enrolled in Health Net’s commercial HMO plans,
    members (or their employers) pay a fixed periodic fee for
    coverage. A Health Net commercial HMO member may be
    responsible for cost-share responsibilities, such as copayments,
    coinsurance, and deductibles, when they obtain medical services.
    Health Net sets its premiums based on the anticipated aggregate
    cost of providing future medical and hospital care to members,
    which it estimates by predicting future costs of providing medical
    care based on past claims “experience” and anticipated changes
    in the health care needs of new membership, changes in benefits,
    the introduction of new medical treatments, and prescription
    drug inflation among other factors.
    When members initially enroll in a Health Net commercial
    HMO plan, they are required to choose an in-network primary
    care physician. Health Net’s contracted primary care physicians
    (in some instances, along with a designated physician group)
    coordinate medical services provided to commercial HMO
    members and assist members with securing their medical care,
    including preventative care and specialist referrals.
    Sample Evidence of Coverage documents for Health Net’s
    commercial HMO plans issued in California during the 2007
    through 2016 period contain the following (or substantially
    similar) language: “When you enroll in this Plan, you must select
    a contracting Physician Group where you want to receive all of
    your medical care. That Physician Group will provide or
    authorize all medical care.” Sample Evidence of Coverage
    documents for Health Net’s commercial HMO plans issued in
    California during the 2007 through 2016 period contain the
    following (or substantially similar) language: “Your Physician
    Group will authorize and coordinate all your care, providing you
    26
    with medical services or supplies. You are financially responsible
    for any required Copayment . . . . However, you are completely
    financially responsible for medical care that the Physician Group
    does not provide or authorize except for Medically Necessary care
    provided in a legitimate emergency. You are also financially
    responsible for care that this Plan does not cover.”
    Health Net’s commercial HMO provider contracts with in-
    network providers between 2007 and 2016 contain the following
    (or substantially similar) language: “Provider agrees that in no
    event shall Provider bill, charge, collect a deposit from, seek
    compensation, remuneration, or reimbursement from, or have
    any recourse against Beneficiaries or persons acting on their
    behalf other than Health Net or a Payor for Contracted Services
    provided pursuant to this Agreement except for Copayments,
    Coinsurance, Deductibles, Excluded Services or permitted third
    party liens.” Health Net compensates health care providers on
    both a capitated and fee-for-service basis.
    Health Net maintains a network of providers for its HMO
    members, which includes approximately 264 California facilities
    and 59,000 California professional providers for Health Net’s
    broadest commercial HMO network. Out-of-network care is
    restricted within Health Net’s commercial HMOs. Sample
    Evidence of Coverage documents for Health Net’s commercial
    HMO plans issued in California during the 2007 through 2016
    period contain the following (or substantially similar) language:
    “Except in an emergency or other urgent medical circumstances,
    the covered services of this plan must be performed by your
    Physician Group or authorized by them to be performed by
    others. You may use other providers outside your Physician
    Group only when you are referred to them by your Physician
    27
    Group.” Health Net or a designated physician group, and not
    commercial HMO members, are responsible for paying all covered
    out-of-network services rendered to commercial HMO members.
    The annual approximate percentage of Health Net’s
    reported in-network expenses as compared to its total medical
    expenses for all Health Net product lines for the years 2007 to
    2016 as reported by Health Net to the DMHC was between 96
    percent to 99 percent. In the combined period of 2007 through
    2016, approximately 98.6 percent of Health Net’s reported health
    care expenses were made to in-network providers as defined by
    the DMHC.8
    4.    Procedural Background
    In 2013, Myers filed this taxpayer action under Code of
    Civil Procedure section 526a against the State Board of
    Equalization, the Insurance Commissioner, and the State
    Controller (collectively, the State Defendants), to compel the
    State Defendants to assess and collect the GPT against Blue
    Cross and Blue Shield. Myers alleged that Blue Cross and Blue
    Shield are among the largest health “insurers” in this state by
    virtue of the significant premiums they collect in exchange for
    agreeing to indemnify their enrollees against contingent medical
    expenses, largely through preferred provider organization plans.
    Myers further alleged that Blue Cross and Blue Shield have not
    8 Myers disputed these facts before the trial court. The court concluded
    that no material dispute existed because Myers did not identify any
    errors or issues with the data relied upon for these conclusions, but
    instead relied on deposition testimony concerning another issue and
    based on different data. We agree that no material dispute of fact
    exists as to these percentages, a point that is not contested on appeal.
    28
    paid the gross premium tax that is paid by other companies that
    issue similar fee-for-service indemnity health insurance
    contracts. He therefore sought mandamus requiring the State
    Defendants to assess and collect back GPT payments for the
    preceding eight years, during which the State Controller had not
    directed the collection of the GPT from Blue Cross or Blue Shield.
    The trial court sustained demurrers filed by Blue Cross and
    Blue Shield, both on res judicata grounds9 and because Blue
    Cross’s and Blue Shield’s status as HCSPs meant that they were
    not subject to the statutes regulating insurers and that they were
    therefore not “insurers” for GPT purposes. A panel of this
    Division reversed the judgment and vacated the order sustaining
    the demurrers. (Myers I, supra, 240 Cal.App.4th at p. 745.) As
    discussed in greater detail infra, the court in Myers I rejected the
    argument that Blue Cross and Blue Shield were not insurers for
    GPT purposes because they are regulated as HCSPs and held
    that the applicable standard was set forth in Roddis: a court
    must “ ‘balanc[e] the indemnity aspects against the direct service
    aspects of the business’ ” and determine whether “ ‘indemnity is a
    significant financial proportion of the business,’ ” in which case it
    is an insurer. (Id., at p. 740.) Applying the Roddis standard to the
    allegations of the petitions, the court concluded that Myers had
    9 In November 2004, the Foundation for Taxpayer and Consumer
    Rights (FTCR) petitioned the court to compel the state agencies to
    collect the GPT from Blue Cross. The central theory in the FTCR case
    was that Blue Cross must be considered and taxed as an “insurer”
    since a substantial portion of its plans were PPO products which are in
    the nature of insurance. The court in the FTCR case ruled against
    FTCR as a matter of law, holding that (1) FTCR had no standing to
    bring an action to enjoin or prevent the collection of a tax, and (2) Blue
    Cross, as an HCSP, is not an “insurer” and the GPT does not apply.
    29
    adequately alleged that a significant financial proportion of Blue
    Cross’s and Blue Shield’s business was indemnity. (Id. at pp.
    740–741.) The court further held that the public interest
    exception to the res judicata doctrine applied. (Id. at pp. 742–
    743.)
    In 2015, Myers filed two further actions seeking to compel
    the State Defendants to assess and collect the GPT against
    Kaiser and Health Net. Myers once again sought mandamus
    requiring the State Defendants to assess and collect back GPT
    payments for the preceding eight years. Both actions were found
    to be related with the Blue Cross and Blue Shield action and
    were reassigned to the same judge.
    Following the enactment of Senate Bill No. X2-2 in 2016,
    Myers stipulated that he seeks the collection of the GPT prior to
    June 30, 2016 and does not seek the collection of the GPT against
    Real Parties in Interest after June 30, 2016.10 In 2017, Kaiser
    and Health Net demurred and Blue Cross and Blue Shield moved
    for judgment on the pleadings, arguing that the change in law
    demonstrated that they were not insurers and that Myers I was
    no longer binding. In 2018, the court found that many of the facts
    urged by the moving parties were not properly subject to judicial
    notice and therefore denied the motions for judgment on the
    pleadings and overruled the demurrers. Blue Shield filed a
    petition seeking writ review of the denial of the motion. A panel
    of this Division issued an order to show cause why the motion
    should not be granted. Following briefing, another panel
    10 Accordingly, the relevant period for Blue Cross and Blue Shield is
    2005 through 2016, and the relevant period for Kaiser and Health Net
    is 2007 through 2016.
    30
    discharged the order, having determined that review of the issues
    raised in this proceeding should await entry of a final judgment
    in the trial court.11
    In 2019 and 2020, Real Parties in Interest moved for
    summary judgment, arguing that they were not insurers under
    the Roddis standard adopted in Myers I because more than 90
    percent of their medical expenses during the relevant period were
    for in-network services, for which members are not personally
    responsible beyond cost-share payments. In support of these
    contentions, Real Parties in Interest submitted declarations from
    executives, advisors, and actuaries, annual reports made to the
    DMHC, and sample contracts with members and providers,
    among other evidence.
    Myers did not dispute the majority of the evidence relied
    upon by Real Parties in Interest.12 However, Myers argued that
    the correct test for whether Real Parties in Interest are insurers
    is whether they spread and underwrite a policyholder’s risk, and
    submitted evidence, including policy forms, agreements, actuarial
    memoranda and certifications, and deposition testimony, to
    support that Real Parties in Interest engage in risk-shifting and
    11 We grant Blue Shield’s motion for judicial notice filed February 2,
    2022, which sought judicial notice of this order, as well as briefs filed
    by the Insurance Commissioner of the State of California in the Myers
    I appeal. (Evid. Code, § 452, subd. (d); Glaski v. Bank of America (2013)
    
    218 Cal.App.4th 1079
    , 1090 [“Courts can take judicial notice of the
    existence, content and authenticity of public records and other
    specified documents . . . .”].)
    12 In many instances, Myers disputed inferences that might be drawn
    from facts he did not dispute. The trial court correctly concluded that
    disputing facts with argument is insufficient to create a dispute of
    material fact.
    31
    held themselves out as insurers. In support of his oppositions,
    Myers also filed declarations from Ian Duncan, Ph.D., who opined
    that Real Parties in Interest use actuaries to calculate reserves
    and premium rates, hold free capital, and effectively operate in
    the same manner as insurers.
    Real Parties in Interest raised evidentiary objections to
    portions of the Duncan declarations, primarily on relevancy and
    foundation grounds, and argued that whether Real Parties in
    Interest assume risk and distribute it among their members, how
    they set rates and compensate healthcare providers, and their
    actuarial practices have no bearing on whether they are insurers
    under the Roddis standard. Health Net and Blue Cross further
    objected to evidence of the payouts they received as insurers
    under the federal Affordable Care Act. Blue Cross and Blue
    Shield also objected to evidence that the PPO plans offered by
    companies affiliated with Blue Cross and Blue Shield are similar
    to those offered by Blue Cross and Blue Shield and that their
    websites and actuarial certificates refer to both as insurers, on
    grounds that such evidence was irrelevant.
    In 2020, the trial court granted the summary judgment
    motions of Real Parties in Interest. The court concluded that the
    Roddis test adopted in Myers I controlled and that indemnity
    under this test means whether the member bears the risk of
    personal liability for medical services.13 The court further
    concluded that, although Real Parties in Interest take on the risk
    that they will pay for the health care needed for their members,
    the record demonstrated that Real Parties in Interest were
    13As to Blue Cross and Blue Shield, the court concluded that Myers I is
    law of the case.
    32
    largely in the business of providing health care and their model is
    therefore one primarily of “service” rather than of “indemnity” as
    those terms are used in Roddis and Myers I. The court sustained
    most of the objections Real Parties in Interest made to the
    Duncan declarations, primarily on relevancy grounds. It also
    sustained many of the additional objections made by Blue Cross,
    Blue Shield, and Health Net on relevancy grounds.
    Myers timely appealed.
    CONTENTIONS
    Myers argues that the trial court incorrectly applied the
    Roddis standard adopted in Myers I. His amicus curiae, the
    Insurance Commissioner, echoes this argument.14 Myers further
    contends that the court in Myers I held that non-capitated
    payments constitute indemnity and that Real Parties in Interest
    are insurers because their payments to healthcare providers are
    primarily non-capitated. He asserts that this court should follow
    federal and California cases that have held that HMOs are
    insurers for purposes of federal preemption law. Myers also
    argues that the business of Real Parties in Interest implicates
    the reasoning underlying the adoption of the GPT.
    Real Parties in Interest and their amicus, the DMHC,
    contend that the trial court correctly understood and applied the
    Roddis standard. They argue that Real Parties in Interest are not
    insurers because it is undisputed that over 90 percent of their
    respective claims costs during the relevant periods were for in-
    14Although identified as a respondent by Myers, the Insurance
    Commissioner argues that summary judgment was not sought against
    him and that he is “not clearly a respondent.” He therefore sought and
    obtained permission to file an amicus curiae brief in support of Myers.
    33
    network services, for which members bear no risk of liability.
    Although Blue Shield and Blue Cross argue that they are not
    insurers under the standard adopted in Myers I, they argue that
    this court should determine that Myers I is no longer the law of
    the case following the adoption of the 2016 MCO tax, which they
    contend demonstrates the Legislature’s understanding that the
    GPT does not apply and never has applied to HCSPs. The DMHC
    similarly contends that the Legislature has never defined or
    treated HCSPs as insurers. Blue Cross also argues that, if this
    court concludes that the law of the case doctrine applies and that
    it is an insurer under the Myers I standard, we should not apply
    Myers I retroactively.
    DISCUSSION
    1.    The court correctly granted summary judgment in
    favor of Real Parties in Interest.
    1.1.   Standard of Review
    “ ‘In evaluating the propriety of a grant of summary
    judgment our review is de novo, and we independently review the
    record before the trial court. [Citation.] In practical effect, we
    assume the role of a trial court and apply the same rules and
    standards which govern a trial court’s determination of a motion
    for summary judgment. [Citation.]’ [Citation.] Section 437c,
    subdivision (c) provides that a motion for summary judgment
    shall be granted if all the papers submitted show there is no

    entitled to judgment as a matter of law. [¶] Where the trial court
    grants summary judgment solely upon the basis of its
    interpretation of statutory and case law, ‘[i]t is well settled that

    interpretation. [Citations.]” (City of San Diego v. Dunkl (2001) 
    86 Cal.App.4th 384
    , 395.)
    1.2.   Under Myers I, Roddis supplies the relevant
    standard for determining whether Real Parties in
    Interest are insurers.
    The first issue before us is the appropriate law to apply to
    the undisputed facts to determine whether Real Parties in
    Interest are insurers for purposes of imposing the GPT tax. The
    trial court concluded that Myers I is law of the case as to Blue
    Cross and Blue Shield and applied the Myers I standard to the
    motions brought by all Real Parties in Interest. Myers and Real
    Parties in Interest argue in the first instance that the trial court’s
    decision was error or correct by reference to Myers I. Thus, we
    begin our analysis with an examination of Myers I before turning
    to the parties’ competing interpretations of that decision.
    1.2.1. Myers I
    In Myers I, a panel of this Division concluded that Myers’s
    petition adequately alleged that Blue Cross and Blue Shield are
    insurers under the GPT provision in the Constitution. (Myers I,
    supra, 240 Cal.App.4th at p. 737.) The allegations of the
    complaint focused on Blue Cross’s and Blue Shield’s PPO plans
    and alleged that Blue Shield paid over three times for non-
    capitated medical expenses than for capitated medical expenses
    and that Blue Shield’s fee-for-services payments on behalf of
    members are five to six times larger than its prepaid capitation
    payments. (Id. at pp. 730–731.) Myers therefore alleged that Blue
    35
    Cross and Blue Shield “receive a substantial portion of their
    premiums each year in exchange for agreeing to indemnify their
    enrollees against a risk of loss occasioned by contingent medical
    expenses, and in doing so, [Blue Cross’s and Blue Shield’s]
    contracts effectively spread the financial risk posed by those
    contingent medical events among the millions of Californians
    who pay premiums to enroll in [Blue Cross’s and Blue Shield’s]
    plans.” (Id. at pp. 738–739.) Myers argued that the trial court
    erred in resolving the “factual issue” of whether Blue Cross and
    Blue Shield are insurers based on their regulatory status as
    HCSPs and that the court “should have applied the test set forth
    in Roddis to assess whether the complaint’s allegations
    concerning [Blue Cross’s and Blue Shield’s] business activities
    supported the claim that they are “insurers” under the
    Constitution’s gross premium tax.” (Id. at p. 739.)
    The Myers I court discussed the taxation of insurance
    companies under California law and the regulatory regime
    applicable to HSCPs before turning to relevant case law. The
    court summarized Roddis, including the “ ‘two policy
    considerations’ ” that drove the Supreme Court’s analysis: “First,
    . . . ‘[w]here indemnity features are present, the member bears
    the risk of personal liability for medical services. This is the
    insurance risk which can be protected against by financial
    reserves to assure that the member will receive the benefits for
    which he has paid.’ [Citation.] As for the second consideration,
    the court emphasized, ‘there is a strong social policy to encourage
    the services which health plans provide the public,’ and the
    Insurance Code’s financial reserve requirements should not
    inhibit the development of health plans to meet that need.
    [Citation.]” (Myers I, supra, 240 Cal.App.4th at p. 740.) The court
    36
    then concluded that “Roddis provides the appropriate standard
    for determining whether an entity should be regarded as an
    ‘insurer’ for purposes of assessing the gross premium tax under
    article XIII, section 28 of the Constitution.” (Id. at pp. 740–741.)
    It further concluded that the “the critical role that financial
    solvency concerns played in the Supreme Court’s formulation of
    the Roddis test” constituted “a distinction without difference”
    when it came to assessing whether an entity is an “insurer”
    under the Constitution’s GPT provision. (Id. at p. 741.)
    The Myers I court also cited another Supreme Court
    decision, Metropolitan Life Ins. Co. v. State Bd. of Equalization
    (1982) 
    32 Cal.3d 649
     (Metropolitan Life), for the proposition that
    “the gross premium tax’s purpose is to ‘exact payments from
    insurers doing business in California’ by ‘approximat[ing] the
    volume of business done in this state, and thus the extent to
    which insurers have availed themselves of the privilege of doing
    business in California[,]’ ” and that courts must therefore “ ‘look
    beyond the formal labels the parties have affixed to their
    transactions” and instead “ ‘discern the true economic substance’
    of the arrangement.” (Myers I, supra, 240 Cal.App.4th at p. 741,
    quoting Metropolitan Life, at p. 656.)
    With this background in mind, the Myers I court concluded
    that the mere fact that Blue Cross and Blue Shield were
    designated HCSPs for regulatory purposes was not
    determinative. (Myers I, supra, 240 Cal.App.4th at p. 741.) It
    observed that “the underlying reason for this state’s adoption of
    the gross premium tax was to simplify the taxation of insurance
    companies that, in contrast to other businesses, have difficulty
    calculating their net profits in a given tax year because they
    collect revenues up front in the form of premiums, then make
    37
    indemnity payments to policyholders based on contingent events
    that occur many months or years later.” (Id. at pp. 741–742.)
    Because Myers had alleged that “under [Blue Cross’s and Blue
    Shield’s] PPO policies they collect premiums up front, but do not
    make payments on the policies unless and until a contingent
    medical event occurs” and that “a significant financial portion of
    their business operations allegedly consist of indemnity
    contracts, the underlying rationale for applying the gross
    premium tax to other insurance companies applies equally to
    Blue Cross and Blue Shield.” (Id. at p. 742.)
    1.2.2. The Roddis definition of indemnity was not
    dictum.
    Myers contends that the Myers I court did not intend to
    adopt the definition of indemnity set forth in Roddis—that is,
    that indemnity aspects are present where a member bears the
    risk of personal liability for medical services. He argues that
    Roddis’s definition of indemnity does not apply because it was a
    case concerning regulatory statutes rather than the GPT, and
    Myers I’s reference to that definition was mere dictum. Relying
    on Metropolitan Life, Myers argues that Blue Cross’s and Blue
    Shield’s PPO plans and the HMO plans of all Real Parties in
    Interest constitute insurance under the California Constitution
    because their plans involve the shifting and distribution of risk.
    Real Parties in Interest contend that the Myers I court gave no
    indication that it was adopting the Roddis standard but not its
    definition of indemnity, nor did it suggest that Metropolitan Life’s
    discussion of the elements of insurance supplied the relevant
    definition. We agree with Real Parties in Interest that the Myers
    I court’s adoption of the Roddis standard included its definition of
    indemnity.
    38
    With respect to Myers’s first contention, the court in
    Myers I recognized that Roddis arose in a different context than
    the case before it and acknowledged that financial solvency
    concerns played a “critical role” in the Supreme Court’s
    determination of Roddis, but concluded that it was “a distinction
    without difference.” (Myers I, supra, 240 Cal.App.4th at p. 741.)
    The court explained that, “[i]n Roddis, the court’s concern over
    financial solvency stemmed from the fact that CMA had promised
    to pay for future contingent medical expenses, yet its ultimate
    liability for such expenses was unknown at the time it collected
    dues from its covered members. The same concern supported
    adoption of the gross premium tax. According to the Legislative
    Analyst’s Office, the economics of insurance indemnity
    arrangements—that is, the fact that insurers receive premiums
    up front, without knowing what related expenses will be paid on
    those premiums in the future, thereby rendering them unable to
    determine the net profits attributable to those premiums at the
    end of the tax year—was the ‘key reason’ for adopting the gross
    premium tax.” (Ibid., italics added.) We find the Myers I court’s
    reasoning persuasive.
    Moreover, there is no indication that the Myers I court
    considered the definitions of indemnity and service set forth in
    Roddis dicta when it summarized and quoted Roddis at length
    and adopted the standard it set forth. (Myers I, supra, 240
    Cal.App.4th at pp. 739–740.) Had the Myers I court intended to
    adopt other definitions of terms that are fundamental to the
    Roddis standard, it presumably would have made that intention
    clear for the benefit of the parties and the trial court.
    Second, although the court in Myers I relied on
    Metropolitan Life for the proposition that the court must look
    39
    beyond labels and “ ‘discern the true economic substance’ of the
    arrangement” to determine whether an HSCP is an insurer
    (Myers I, supra, 240 Cal.App.4th at p. 741, quoting Metropolitan
    Life, supra, 32 Cal.3d at p. 656), we find no basis to conclude that
    Metropolitan Life provides the relevant standard for making that
    determination.
    The issue before the Supreme Court in Metropolitan Life
    was “whether certain amounts, though never formally paid to
    Metropolitan Life Insurance Company (Metropolitan),
    nevertheless are to be included within the gross premiums
    measure of the tax imposed on its business done in California.”
    (Metropolitan Life, supra, 32 Cal.3d at p. 652.) Metropolitan’s
    “Mini-Met” plan was the subject of the controversy before the
    court. Prior to Mini-Met, Metropolitan offered employers a
    standard group policy pursuant to which the employers paid a
    premium in return for Metropolitan’s assumption of the entire
    obligation to provide health coverage to benefitted employees.
    (Ibid.) To reduce the cost of insurance coverage for employers and
    to improve their cash-flow situation, Metropolitan developed the
    Mini-Met rider to the standard group policy, which shifted
    certain cash-flow advantages to the employers and sought to
    substantially reduce Metropolitan’s GPT liability. (Id. at p. 653.)
    “The Mini-Met rider required employers to assume the obligation
    to pay all employee claims for benefits up to a ‘trigger-point’
    amount, defined as the actuarially predicted, monthly average
    level of aggregate employee claims. Metropolitan remained
    obligated to pay all claims in excess of that amount.” (Ibid.) For
    the three tax years in question, Metropolitan argued that it was
    entitled to a 90 percent reduction in its GPT liability as a
    consequence of the Mini-Met rider, but the California Insurance
    40
    Commissioner levied a tax based upon the sum of the amounts
    employers paid to Metropolitan as premiums plus the aggregate
    yearly claims paid to employees from employers’ funds. (Ibid.)
    Metropolitan sued for a refund of the tax assessments and
    interest it had paid the State Board of Equalization and obtained
    a judgment for the full amount requested, which the Board
    appealed. (Id. at p. 654.)
    Ruling in bank, the Supreme Court reversed. (Metropolitan
    Life, supra, 32 Cal.3d at p. 662.) The court observed that
    “insurance necessarily involves two elements: (1) a risk of loss to
    which one party is subject and a shifting of that risk to another
    party; and (2) distribution of risk among similarly situated
    persons. [Citations.]” (Id. at p. 654.) The court explained that
    “[t]he presence or absence of insurance risk on the part of the
    employers is not alone determinative of Metropolitan’s tax
    liability . . . . In attempting to fulfill the purpose of the gross
    premiums tax, it is preferable to look beyond the formal labels
    the parties have affixed to their transactions and seek, rather, to
    discern the true economic substance of the Mini-Met
    arrangement.” (Id. at pp. 656–657.) The court concluded that “the
    employers under the Mini-Met arrangement functioned not as
    independent insurers but as ‘mere [agents] or [distributors] of
    funds[,]’ ” as Metropolitan “determined the amount of all benefits
    to be paid in satisfaction of employee claims, both above and
    below the trigger point.” (Id. at p. 657.) The court concluded that
    “that there was but one insurer under the Mini-Met package and
    that the employers functioned as agents of that insurer.” (Id. at
    p. 659.)
    Thus, Metropolitan Life was not a case concerning the
    classification of HCSPs for regulatory or taxation purposes, nor
    41
    was there any dispute in that case as to whether Metropolitan
    was an insurer or subject to the GPT. Further, and more
    importantly for our purposes, the Myers I court stated
    unequivocally that Roddis provides the relevant standard. (Myers
    I, supra, 240 Cal.App.4th at p. 740.) The court was clearly aware
    of Metropolitan Life and could have concluded that the presence
    of the two elements of insurance described in Metropolitan Life
    determined whether an HCSP is an insurer. It did not do so.
    Indeed, to conclude that the presence of risk of loss and
    distribution of risk settle the question would not comport with
    Metropolitan Life’s acknowledgment that “[t]he presence or
    absence of insurance risk” is not determinative of GPT liability
    (Metropolitan Life, supra, 32 Cal.3d at pp. 656–657), or with the
    Supreme Court’s observation in Garrison that the “[a]bsence or
    presence of assumption of risk or peril is not the sole test to be
    applied in determining its status” and that the more important
    question is “whether looking at the plan of operation as a whole,
    ‘service’ rather than ‘indemnity’ is its principal object and
    purpose. [Citations.]” (Garrison, supra, 28 Cal.2d at p. 809.)
    Thus, while Metropolitan Life is relevant to our analysis, we find
    no basis to prioritize language in that decision over the standard
    expressly adopted by the Myers I court.
    1.2.3. Whether the payments made by Real Parties in
    Interest for in-network services were capitated
    or non-capitated is not part of the standard
    adopted in Myers I.
    Myers further argues that the trial court incorrectly
    applied the law when it concluded that whether payments made
    by Real Parties in Interest were capitated or non-capitated was
    irrelevant under Roddis. In Myers I, the court recited the
    42
    allegations that Blue Shield’s and Blue Cross’s non-capitated
    payments exceeded their capitated payments. (Myers I, supra,
    240 Cal.App.4th at p. 730.) The complaint alleged that non-
    capitated payments were indemnity payments and that capitated
    payments were not. The Myers I court accepted these allegations
    and concluded that Myers had adequately stated a claim that
    Blue Cross and Blue Shield should be regarded as “insurers” for
    purposes of the GPT. (Id. at p. 742.) Myers therefore argues that
    the court in Myers I made a legal determination that non-
    capitated payments constituted indemnity. We again disagree.
    Myers fails to explain how we can reconcile the Myers I
    court’s explicit adoption of Roddis as the relevant standard with
    a legal conclusion that non-capitated payments constitute
    indemnity for purposes of determining whether an HCSP is an
    insurer. The payments CMA made to the 38 physicians in Roddis
    were non-capitated—that is, CMA paid its contracted physicians
    scheduled fees for services rendered, rather than fixed amounts
    per member (Roddis, supra, 68 Cal.2d at pp. 678–679)—and the
    court concluded that “CMA’s contracts with the 38 physicians
    provide for direct service without indemnity[]” because the
    physicians had agreed not to seek reimbursement from CMA’s
    members. (Id. at p. 683, italics added.) If non-capitated payments
    constituted indemnity under the standard set forth in Roddis, the
    Supreme Court could have concluded that CMA was primarily in
    the business of indemnity without instructing the trial court to
    retry the case and determine what proportion of CMA’s members
    was treated by the 38 contracted physicians.
    Further, the conclusion that non-capitated payments are
    indemnity does not follow logically from the Roddis standard.
    The method an HCSP chooses to compensate its healthcare
    43
    providers has no bearing on whether its members are at risk of
    personal liability for medical services. If we accepted Myers’s
    contention that the Myers I court made a legal determination
    that non-capitated payments constitute indemnity because they
    “effectively spread the financial risk posed by those contingent
    medical events among the millions of Californians who pay
    premiums to enroll in Real Parties in Interest’s . . . plans,” as
    Myers alleged (Myers I, supra, 240 Cal.App.4th at p. 739), it
    would follow that Myers I did not actually follow the Roddis
    standard, as it claimed to do. The Roddis opinion does not
    mention risk shifting or spreading, much less state that the
    spreading of risk is the test for indemnity. Rather, citing
    Garrison, the Supreme Court observed that “ ‘[a]bsence or
    presence of assumption of risk or peril is not the sole test to be
    applied in determining its status[,]’ ” and instead adopted a test
    in which indemnity was associated with a member’s risk of
    personal liability. (Roddis, supra, 68 Cal.2d at p. 682.)
    Faced with two possible standards, one of which the Myers
    I court expressly adopted and the other which may, at best, be
    implied by the conclusion it reached based on the allegations of
    the complaint, which it was required to accept as true (Myers I,
    supra, 240 Cal.App.4th at p. 727, fn. 1), we choose the former. We
    therefore agree with the trial court that whether payments are
    capitated or non-capitated does not determine whether Real
    Parties in Interest are insurers.
    1.3.   The law of the case doctrine requires us to apply
    the Roddis standard in this appeal.
    Having established our understanding of the standard
    adopted in Myers I, we consider whether we remain bound by
    that decision. “Under the law of the case doctrine, when an
    44
    appellate court ‘ “states in its opinion a principle or rule of law
    necessary to the decision, that principle or rule becomes the law
    of the case and must be adhered to throughout [the case’s]
    subsequent progress, both in the lower court and upon
    subsequent appeal . . . .” ’ [Citation.] Absent an applicable
    exception, the doctrine ‘requir[es] both trial and appellate courts
    to follow the rules laid down upon a former appeal whether such
    rules are right or wrong.’ [Citation.] As its name suggests, the
    doctrine applies only to an appellate court’s decision on a
    question of law; it does not apply to questions of fact. [Citation.]”
    (People v. Barragan (2004) 
    32 Cal.4th 236
    , 246.) “The doctrine of
    law of the case . . . governs later proceedings in the same case
    [citation] with regard to the rights of the same parties who were
    before the court in the prior appeal. [Citations.]” (In re
    Rosenkrantz (2002) 
    29 Cal.4th 616
    , 668.) Myers, Blue Cross and
    Blue Shield do not dispute that the adoption of the Roddis
    standard was necessary to the court’s decision in Myers I, or that
    they were parties to the prior appeal.15 Thus, unless an exception
    to the law of the case principle applies, we are bound by the legal
    standard set forth in Myers I.
    15Though Health Net and Kaiser are not bound by Myers I under the
    law of the case doctrine because they were not parties in the prior
    appeal, both argue that the Roddis standard should apply. Although
    we are generally not bound by decisions made by a different panel of
    this Division (Tourgeman v. Nelson & Kennard (2014) 
    222 Cal.App.4th 1447
    , 1456, fn. 7), “ ‘[w]e respect stare decisis . . . which serves the
    important goals of stability in the law and predictability of decision.’ ”
    (People v. The North River Ins. Co. (2019) 
    41 Cal.App.5th 443
    , 455.)
    Since neither Kaiser nor Health Net advances a “ ‘good reason to
    disagree[]’ ” with the standard adopted in Myers I (ibid.), we decline to
    consider whether a different rule of law should apply to those parties.

    Exceptions to the law of the case doctrine are limited to two
    situations: if its application will result in an unjust decision or if
    the controlling rules of law have changed in the interim. (People
    v. Stanley (1995) 
    10 Cal.4th 764
    , 787.) For the “unjust decision”
    exception to apply, “there must at least be demonstrated a
    manifest misapplication of existing principles resulting in
    substantial injustice.” (People v. Shuey (1975) 
    13 Cal.3d 835
    , 846,
    disapproved on another ground in People v. Bennett (1998) 
    17 Cal.4th 373
    , 389, fn. 5.) An intervening change in the law exists
    “ ‘where the controlling rules of law have been altered or clarified
    by a decision intervening between the first and the second
    determinations of the appellate courts.’ [Citation.]” (In re
    Saldana (1997) 
    57 Cal.App.4th 620
    , 625.) This includes
    legislative changes or clarifications. (Renee J. v. Superior Court
    (2002) 
    96 Cal.App.4th 1450
    , 1463 (Renee J.).)
    Although Myers repeatedly states that Myers I is law of the
    case and thus binding on this court, he argues that this court
    should follow cases that were not mentioned in the Myers I
    opinion and which conclude that HMOs are insurers for purposes
    of federal preemption law. He also contends that the Roddis
    standard yields results that are both inconsistent with the
    purpose underlying the GPT and absurd when applied to other
    insurers. Notwithstanding the inconsistency of these contentions,
    we opt to consider whether Myers demonstrates that Myers I
    constitutes “a manifest misapplication of existing principles
    resulting in substantial injustice” that would permit us to apply
    another legal standard. (People v. Shuey, supra, 13 Cal.3d at
    p. 846.) We further address Blue Cross’s and Blue Shield’s
    contention that the 2016 MCO tax constitutes a change in the
    controlling law that requires us to set Myers I aside. We conclude
    46
    that neither exception applies and that Myers I remains law of
    the case.
    1.3.1. Cases defining insurance for purposes of federal
    preemption law do not override the application
    of the law of the case doctrine.
    Myers argues that cases concluding that HMOs are
    insurers for purposes of federal preemption dictate the conclusion
    that Real Parties in Interest are insurers subject to the GPT.
    These cases are inapposite and do not demonstrate that Myers I’s
    adoption of the Roddis standard is inconsistent with existing
    legal principles or substantially unjust.
    In Rush Prudential HMO, Inc. v. Moran (2002) 
    536 U.S. 355
    , 359, the United States Supreme Court considered whether
    an Illinois statute, which “provides recipients of health coverage
    by such organizations with a right to independent medical review
    of certain denials of benefits,” was preempted by the Employee
    Retirement Income Security Act of 1974 (ERISA). “To ‘safeguard
    . . . the establishment, operation, and administration’ of employee
    benefit plans, ERISA . . . contains an express preemption
    provision that ERISA ‘shall supersede any and all State laws
    insofar as they may now or hereafter relate to any employee
    benefit plan[,]’ ” but a “saving clause then reclaims a substantial
    amount of ground with its provision that ‘nothing in this
    subchapter shall be construed to exempt or relieve any person
    from any law of any State which regulates insurance, banking, or
    securities.’ ” (Id. at p. 364.) The court adopted a “ ‘common-sense
    view of the matter[,]’ ” under which “ ‘a law must not just have an
    impact on the insurance industry, but must be specifically
    directed toward that industry.’ [Citation.]” (Id. at pp. 365–366.)
    This inquiry also “focuses on ‘primary elements of an insurance
    47
    contract[, which] are the spreading and underwriting of a
    policyholder’s risk.’ [Citation.]” (Id. at p. 366.) The court observed
    that “ ‘[t]he defining feature of an HMO is receipt of a fixed fee
    for each patient enrolled under the terms of a contract to provide
    specified health care if needed.’ [Citation.] ‘The HMO thus
    assumes the financial risk of providing the benefits promised: if a
    participant never gets sick, the HMO keeps the money
    regardless, and if a participant becomes expensively ill, the HMO
    is responsible for the treatment . . . .’ ” (Id. at p. 367.) The court
    concluded that the defendant, an HMO, “cannot checkmate
    common sense by trying to submerge HMOs’ insurance features
    beneath an exclusive characterization of HMOs as providers of
    health care” in order to argue that the Illinois law was preempted
    by ERISA. (Id. at p. 370.)
    The court also “test[ed] the results of the commonsense
    enquiry by employing the three factors used to point to insurance
    laws spared from federal preemption under the McCarran-
    Ferguson Act, 
    15 U.S.C. § 1011
     et seq. [(McCarran-Ferguson
    Act)].” (Rush Prudential HMO, Inc. v. Moran, 
    supra,
     536 U.S. at
    p. 366.) “A law regulating insurance for McCarran-Ferguson
    purposes targets practices or provisions that ‘have the effect of
    transferring or spreading a policyholder’s risk; . . . [that are] an
    integral part of the policy relationship between the insurer and
    the insured; and [are] limited to entities within the insurance
    industry.’ ” (Id. at p. 373.) The court concluded that at least the
    second and third requirements were “clearly satisfied” by the
    Illinois statute at issue. (Ibid.)
    In Smith v. PacifiCare Behavioral Health of California, Inc.
    (2001) 
    93 Cal.App.4th 139
     (Smith), the issue before the court was
    “whether a health care service plan may enforce an arbitration
    48
    clause contained in the plan and in related subscriber
    agreements which does not comply with the [state] statutory
    disclosure requirements applicable to such clauses.” Specifically,
    the court considered whether the McCarran-Ferguson Act
    overrode the Federal Arbitration Act (
    9 U.S.C. § 1
     et seq.) and
    precluded its preemptive impact on the state statute on the
    ground that the statute “constitutes a regulation of the business
    of insurance within the meaning of McCarran-Ferguson.” (Id. at
    p. 143.) This Division observed that “HMO’s or health care
    service plans . . . are engaged in providing a service that is a
    substitute for what previously constituted health insurance.” (Id.
    at p. 157.) The court concluded that, for purposes of the
    McCarran-Ferguson Act, the defendant, “PacifiCare, as a health
    care service plan (or HMO), is engaged in the business of
    insurance.” (Ibid.) The Smith court noted that “the Legislature
    has reached the same conclusion in a very public way. It has
    expressly recognized that health care service plans in California
    are engaged in the business of insurance within the meaning of
    the McCarran-Ferguson Act[]” by enacting the Managed Health
    Care Insurance Accountability Act of 1999, Statutes 1999,
    chapter 536 (Sen. Bill No. 21) section 2, partially codified at Civil
    Code section 3428. (Id. at p. 158.) “In an uncodified section 2 to
    the act, the Legislature stated: ‘SEC. 2. (a) The Legislature finds
    and declares as follows: [¶] “(1) Based on the fundamental nature
    of the relationships involved, a health care service plan and all
    other managed care entities regulated under the Health and
    Safety Code are engaged in the business of insurance in this state
    as that term is defined for purposes of the McCarran-Ferguson Act
    . . . . Nothing in this act shall be construed to impose the
    49
    regulatory requirements of the Insurance Code on health care
    service plans regulated by the Health and Safety Code.” ’ ” (Ibid.)
    The Smith court rejected PacifiCare’s reliance on Williams
    v. California Physicians’ Service (1999) 
    72 Cal.App.4th 722
     for
    the proposition that it was not in the business of insurance for
    McCarran-Ferguson purposes, noting that Williams “did not even
    address the issue before us. Williams simply held that a health
    care service plan regulated by the Knox-Keene Act was not
    necessarily the equivalent to an insurance company for
    regulatory purposes. Williams did not purport to address the
    issue confronting this court. Rather, it simply recognized that the
    Legislature has elected to subject insurers and health care service
    plans to distinct regulatory regimes.” (Smith, supra, 93
    Cal.App.4th at pp. 158–159.)
    The cases on which Myers relies do not purport to address
    whether HCSPs are insurers for state taxation purposes and thus
    do not bear on our determination of whether Real Parties in
    Interest are insurers for purposes of taxation under California
    law. “The clear purpose of McCarran-Ferguson was . . . to insure
    that the states would continue to enjoy broad authority in
    regulating the dealings between insurers and their
    policyholders.” (Smith, supra, 93 Cal.App.4th at p. 153.) This
    purpose has no relevance to the case before us.
    Article XIII, section 28 of the California Constitution
    defines “insurer” as including, among other things, “insurance
    companies”—not as any company or association that is “in the
    business of insurance,” the test applied in the ERISA and
    McCarran-Ferguson contexts. Courts interpreting McCarran-
    Ferguson have declined to limit its reach to laws specifically
    concerning insurance companies. (See Barnett Bank of Marion
    50
    County, N.A. v. Nelson (1996) 
    517 U.S. 25
    , 39–41 [law that
    permitted banks to act as agents of insurance companies was
    related to the business of insurance, even if statute did not
    “relate predominantly to insurance” but to banking]; Gordon v.
    Ford Motor Credit Co. (N.D. Cal. 1992) 
    868 F.Supp. 1191
    , 1194
    [rejecting auto financing company’s contention that the
    McCarran-Ferguson Act exemption should apply only to
    traditional insurers].) Further, as set forth in Smith, it is
    sufficient for McCarran-Ferguson Act purposes that a company is
    “engaged in providing a service that is a substitute for what
    previously constituted health insurance.” (Smith, supra, 93
    Cal.App.4th at p. 157.) In contrast, in Roddis, the California
    Supreme Court discussed how “a health plan is similar to
    insurance in that it purports to cover a future contingency,” yet
    concluded that whether HCSPs were insurers depended on the
    application of the balancing of its service and indemnity
    functions. (Roddis, supra, 68 Cal.2d at p. 681.) In other words,
    our Supreme Court declined to hold that the mere assumption
    and transfer of risk, or the fact that insurers and HCSPs fulfill
    similar functions, rendered HCSPs insurers for regulatory
    purposes. We see no reason why these similarities would be
    sufficient to render an HCSP an insurer for tax purposes under
    California law either.
    Further, our Legislature has acknowledged that HCSPs are
    insurers for purposes of the McCarran-Ferguson Act while
    making it clear that such interpretation does not render them
    subject to regulation as insurers for purposes of state law.
    (Smith, supra, 93 Cal.App.4th at p. 158.) Just as the court in
    Smith concluded that Williams v. California Physicians’ Service,
    supra, 
    72 Cal.App.4th 722
     did not provide guidance as to whether
    51
    an HCSP is in the business of insurance for McCarran-Ferguson
    purposes because it concerned California regulations, cases
    holding that HCSPs are insurers for purposes of McCarran-
    Ferguson and ERISA are not instructive in determining whether
    Real Parties in Interest are insurers for state taxation purposes.
    (Smith, at pp. 158–159.)
    Thus, the Myers I court did not misapply existing legal
    principles under California law when it declined to adopt the
    assumption of risk as its standard for whether an entity is an
    insurer.
    1.3.2. Myers fails to otherwise establish the
    application of the Roddis standard will yield
    unjust or absurd results.
    Myers also argues that the businesses of Real Parties in
    Interest implicate the key reason for adopting the GPT. Because
    the Roddis standard does not require the court to consider
    whether HCSPs are able to match their revenues and related
    expenses, we understand this to be another contention that Myers
    I adopted a standard that is inconsistent with existing legal
    principles and results in unjust outcomes.
    As discussed, the GPT was adopted because it is difficult
    for traditional insurers to match revenues with related expenses
    because they “collect their revenues up front [in the form of
    premiums], then make payments to policyholders based on
    contingent events that occur many months or years later.” (Myers
    I, supra, 240 Cal.App.4th at p. 736, quoting Legis. Analyst,
    Investment Income and the Insurance Gross Premiums Tax (July
    2008) p. 3.) Accordingly, “an accurate determination of the
    theoretically appropriate amount of taxable income proves very
    difficult to achieve in practice.” (Ibid.) Myers contends Real
    52
    Parties in Interest do not know the total expenses incurred by
    members, or their net profits by the end of each year. Myers
    relies on reports Real Parties in Interest filed with the DMHC,
    which reflect that Real Parties in Interest had incurred but not
    reported (INBR) claims and claims payable as of December 31 of
    each year. Because Real Parties in Interest were unable to fully
    match revenues and expenses by the end of the year, he argues
    that their businesses implicate the purpose behind the GPT.
    Real Parties in Interest offer several responses to this
    contention. First, Real Parties in Interest point out the business
    of HCSPs differs from that of traditional insurers in a
    fundamental way. A claim for an automobile accident or work
    injury encompasses all costs associated with that accident or
    injury and will not close until all costs relating to the triggering
    event are paid, which results in the possibility that a claim may
    be open for years or even decades. In contrast, HCSP claims are
    defined by the individual medical service provided. A claim is
    incurred when the service is provided and closes when the bill for
    that specific service is paid, and HCSPs are required by law to
    pay claims within a short period: 30 working days for PPOs and
    45 working days for HMOs. (Health & Saf. Code, § 1371, subd.
    (a)(1).) Health Net notes that, under its plans, charges for
    member coverage are paid for services rendered within the period
    associated with the charge. In other words, a monthly charge to a
    member is associated with and covers that month of coverage,
    and thus there can be no significant temporal disconnect between
    its revenues and expenses.
    Kaiser argues that the short delay in pinning down its
    expenses is an artifact of the accounts payable cycle and is not
    because it has potential liabilities stretching months or years into
    53
    the future. An HCSP may incur expenses late in the calendar
    year which a provider may not immediately submit, and the
    HCSP then has another 30 or 45 working days to pay or contest
    that claim under the Knox-Keene Act. Further, Kaiser notes that
    the DMHC reports on which Myers relies demonstrate that the
    vast majority of its revenues and expenses are known with
    certainty as of the end of the tax year. As an example, in 2014,
    Kaiser’s DMHC reports show that 97.4 percent of its revenues
    and related expenses occurred and were known as of December
    31, 2014—that is, Kaiser’s total medical and hospital expenses
    were approximately $50.6 billion and its claims payable and
    INBR totaled approximately $1.4 billion.
    Similarly, Blue Shield contends that Myers has failed to
    dispute the trial court’s conclusion that the nature of Blue
    Shield’s payment obligations shows the rationale for applying the
    GPT to insurers does not exist. Blue Shield submitted evidence to
    the trial court that it pays most claims within 30 days and almost
    all claims within 90 days. For example, in 2015, Blue Shield paid
    an average of approximately 77 percent of claims within 30 days
    of receiving them and paid approximately 97 percent within 90
    days. Blue Shield also contends that its INBR claims and claims
    payable reports establish that Blue Shield can and does match
    revenues and expenses because they show known costs that have
    been incurred and will be paid shortly, and thus are comparable
    to a short-term accounts payable.
    Finally, Blue Cross argues that the December 31 cutoff in
    the DMHC reports on which Myers relies is not pertinent to its
    business. During the relevant period, Blue Cross submitted its
    tax returns by the state and federal due date (under extension) of
    October the following year, by which time it had paid more than
    54
    99 percent of its claims expenses. For each tax year during the
    relevant period, Blue Cross was able to and did use its actual
    claims expenses from January through August of the following
    tax year for purposes of determining its taxable income for that
    tax year. Thus, by the time it paid its taxes, Blue Cross knew all
    but the smallest fraction of its expenses.
    Myers’s sole response to these varied arguments is that
    Real Parties in Interest cannot actually identify the bulk of their
    expenses by the time that they must pay their taxes because
    “they collectively report billions of dollars in ‘Incurred But Not
    Reported’ and ‘Unpaid Claims’ in their annual statements at the
    end of each calendar year that attempt to estimate those
    unknown claim costs.” However, Myers makes no attempt to
    contextualize this figure. As noted, Kaiser’s total medical and
    hospital expenses in 2014 were approximately $50.6 billion. The
    record indicates that Blue Cross’s total medical and hospital
    expenses for the same year were approximately $9.6 billion, Blue
    Shield’s were approximately $9.5 billion, and Health Net’s were
    approximately $6.4 billion. Thus, the fact that Real Parties in
    Interest collectively reported billions in INBR and claims payable
    to the DMHC does not refute their contention that they do not
    face unknown expenses extending far into the future that are
    significant in the context of their businesses. We further reject
    Myers’s suggestion that any unknown expenses as of December
    31 demonstrates that the logic underlying the GPT applies. We
    conclude that Myers has failed to identify evidence supporting
    that the application of Myers I would be substantially unjust
    considering the purpose underlying the GPT’s adoption.
    Myers also argues that the Roddis standard adopted in
    Myers I would yield absurd results if applied to certain types of
    55
    insurers. For example, an insured has no personal liability for
    risks covered by life or disability insurance. Thus, entities
    providing those types of insurance would be found not to be
    insurers under the Roddis standard. However, as Kaiser points
    out, Roddis did not set forth an all-purpose test for determining
    whether any entity is an insurer. The Roddis court observed that
    “[h]ealth care service plans were given special legislative
    treatment because of the direct service feature” and made clear
    that any workable test to determine whether an HCSP is an
    insurer must take that function into consideration. (Roddis,
    supra, 68 Cal.2d at p. 683.) Insurers that do not have a direct
    service component to their business have no grounds to argue
    that this standard applies to them. Accordingly, this argument
    does not persuade us that the adoption of the Roddis standard is
    absurd or unjust.
    1.3.3. The 2016 MCO tax does not constitute an
    intervening change or clarification of law that
    overrides the law of the case doctrine.
    Blue Cross and Blue Shield argue that the 2016 MCO tax
    constitutes an intervening clarification of the law that overrides
    the application of the law of the case. They argue that the
    Legislature could not impose an MCO tax on HCSPs if it
    understood them to be insurers, which are subject to the GPT in
    lieu of nearly all other taxes. Thus, even though the HCSPs were
    not subject to an MCO tax during the relevant periods for this
    litigation, the 2016 MCO tax demonstrated the Legislature’s
    understanding that HCSPs are not and never were insurers
    under article XIII, section 28 of the Constitution.
    Myers contends that this argument is flawed for two
    reasons. He argues that the Legislature lacks the authority to
    56
    limit a constitutional tax like the GPT. He also contends that the
    legislative history demonstrates that the Legislature did not
    enact the 2016 MCO tax or the subsequent 2019 tax with the
    intent of removing HCSPs from the definition of insurers subject
    to the GPT.
    With respect to the first contention, Myers argues that the
    Legislature lacks the authority to interpret the definition of
    insurer because the Supreme Court “perceive[d] no ambiguity
    either patent or latent in section 28 that would authorize us to
    look beyond the plain meaning of the words.” (Mutual Life Ins.
    Co., 
    supra,
     50 Cal.3d at p. 407.)16
    “[A]n act of the [L]egislature which conflicts with the
    Constitution is void [citation] . . . .” (Robison v. Payne (1937) 
    20 Cal.App.2d 103
    , 106.) The constitutional amendment providing
    for the GPT was originally adopted in 1910 (Bankers Life Co. v.
    Richardson (1923) 
    192 Cal. 113
    , 114–116; former Article XIII,
    § 14, subd. (b)), but was enacted in its current form in 1974,
    decades after the advent of HCSPs. If the constitutional
    definition of insurers included HCSPs, the Legislature would lack
    the authority to exclude them from the GPT. It does not.
    Moreover, “ ‘[i]nsurer’ ” is defined by the Constitution to
    “include[] insurance companies or associations and reciprocal or
    interinsurance exchanges . . . and the State Compensation
    Insurance Fund.” (Cal. Const., art. XIII, § 28, subd. (a), italics
    added.) “The term ‘includes’ is ordinarily a word of enlargement
    16In Mutual Life, there was no dispute that Mutual Life Insurance
    Company of New York was an insurer, only whether it was subject to
    the GPT when it owned and rented out property and operated a
    parking lot in California but did not conduct insurance business in the
    state. (Mutual Life Ins. Co., supra, 50 Cal.3d at p. 406.)
    57
    and not of limitation.” (People v. Western Air Lines, Inc. (1954) 
    42 Cal.2d 621
    , 639.) “When a word in the California Constitution . . .
    is capable of several interpretations, a statutory construction of
    that word is to be afforded substantial deference. [Citation.] This
    rule of deference arises from the fact that the state Constitution,
    unlike the federal Constitution, is a limitation on the power of
    the Legislature rather than a grant of power to it. Any
    constitutional limitation on legislative power is to be narrowly
    construed, and a strong presumption of constitutionality supports
    the Legislature’s acts. [Citation.] The Legislature’s efforts to
    interpret a word in the state Constitution are to be upheld ‘unless
    they are disclosed to be unreasonable or clearly inconsistent with
    the express language or clear import of the Constitution.’
    [Citation.]” (People v. 8,000 Punchboard Card Devices (1983) 
    142 Cal.App.3d 618
    , 620–621; cf. Heckendorn v. City of San Marino
    (1986) 
    42 Cal.3d 481
    , 488.) The plain language of the GPT
    provision leaves open the possibility that other entities than
    those expressly listed may be insurers subject to the GPT. Since
    the Legislature has the authority to determine what, if any,
    entities beyond insurance companies, interinsurance exchanges,
    and the State Compensation Insurance Fund constitute insurers,
    it follows that the Legislature has the authority to determine
    that an entity not expressly listed in the constitutional definition
    is not an insurer. Thus, we reject Myers’s contention that the
    Legislature lacks the authority to exclude HCSPs from the
    definition of “insurers” under the Constitution.
    Whether Senate Bill No. X2-2 overrides the application of
    the law of the case doctrine presents a closer question. The
    legislative history of Senate Bill No. X2-2 reflects that its purpose
    was to reform the existing MCO provider tax, which was paid
    58
    only by Medi-Cal plans, and replace it with a tax that would be
    imposed on all HCSPs for a period of three years with the goal of
    “generat[ing] an amount of nonfederal funds for the Medi-Cal
    program, equivalent to the sales tax currently imposed on MCPs”
    and thus “comply[ing] with federal Medicaid requirements.”
    (Former Welf. & Inst. Code, § 14199.50; Sen. Bill No. X2-2,
    Proposed Conference Report No. 1, Feb. 25, 2016, p. 1.) The 2016
    MCO tax would not be collected unless and until DHCS received
    approval from the federal government that the tax was
    permissible under federal regulations. (Stats. 2015–2016, 2nd Ex.
    Sess., ch. 2, pp. 6029–6030.) Thus, although we agree with Blue
    Cross and Blue Shield that the imposition of the MCO tax on
    HCSPs is inconsistent with an understanding that HCSPs are
    insurers subject to the GPT, the history and language of Senate
    Bill No. X2-2 does not support that its purpose was to address
    Myers I or to clarify that HCSPs are not “insurers” under the
    Constitution for periods before the MCO tax took effect. We
    therefore consider whether the 2016 legislation may be
    understood as a change or clarification of the law that overrides
    the application of the law of the case doctrine, even if the
    Legislature did not express this intent.
    As our Supreme Court has explained, “[i]t is true that if the
    courts have not yet finally and conclusively interpreted a statute
    and are in the process of doing so, a declaration of a later
    Legislature as to what an earlier Legislature intended is entitled
    to consideration. [Citation.] But even then, ‘a legislative
    declaration of an existing statute’s meaning’ is but a factor for a
    court to consider and ‘is neither binding nor conclusive in
    construing the statute.’ [Citations.] This is because the
    ‘Legislature has no authority to interpret a statute. That is a
    59
    judicial task. The Legislature may define the meaning of
    statutory language by a present legislative enactment which,
    subject to constitutional restraints, it may deem retroactive. But
    it has no legislative authority simply to say what it did mean.’ ”
    (McClung v. Employment Development Dept. (2004) 
    34 Cal.4th 467
    , 473.)
    Contrary to Myers’s contention, neither Roddis nor
    Metropolitan Life offers a final and conclusive interpretation of
    the Knox-Keene Act with respect to the issues raised in this
    appeal, as Roddis arose under a prior legislative scheme and did
    not address taxation issues, and Metropolitan Life did not
    concern HCSPs at all. Nevertheless, McClung is instructive. To
    the extent Senate Bill No. X2-2 addressed the appropriate
    taxation of HCSPs before July 2016 in light of the Knox-Keene
    Act, it did so only implicitly. Senate Bill No. X2-2 did not “define
    the meaning of statutory language by a present legislative
    enactment”—for example, by enacting language establishing that
    HCSPs regulated under the Knox-Keene Act are not insurers
    under article XIII, section 28—or deem any such definition
    retroactive. (McClung v. Employment Development Dept., 
    supra,
    34 Cal.4th at p. 473.) Thus, even if we accept that Senate Bill No.
    X2-2 reflects the Legislature’s understanding of what an earlier
    Legislature intended with respect to the effect of the Knox-Keene
    Act on the tax treatment of HCSPs, the Legislature’s non-binding
    interpretation of existing law does not appear to constitute a
    change or clarification of the law that would override the
    application of the law of the case doctrine.
    Renee J., supra, 
    96 Cal.App.4th 1450
     provides further
    guidance. In that case, the appellant argued that the trial court
    had erred in terminating her reunification services based upon a
    60
    Supreme Court decision at an earlier phase of proceedings that
    interpreted the relevant statute, since the Legislature
    subsequently amended that statute. (Id. at p. 1459.)17 Quoting
    Western Security Bank v. Superior Court (1997) 
    15 Cal.4th 232
    ,
    the court in Renee J. explained that “ ‘a legislative declaration of
    an existing statute’s meaning is neither binding nor conclusive in
    construing the statute. Ultimately, the interpretation of a statute
    is an exercise of the judicial power the Constitution assigns to the
    courts. [Citations.] Indeed, there is little logic and some
    incongruity in the notion that one Legislature may speak
    authoritatively on the intent of an earlier Legislature’s
    enactment when a gulf of decades separates the two bodies.
    [Citation.] Nevertheless, the Legislature’s expressed views on the
    prior import of its statutes are entitled to due consideration, and
    we cannot disregard them . . . . [E]ven if the court does not accept
    the Legislature’s assurance that an unmistakable change in the
    law is merely a “clarification,” the declaration of intent may still
    effectively reflect the Legislature’s purpose to achieve a
    17The statute at issue was Welfare and Institutions Code section
    361.5, former subdivision (b)(10). (Renee J., supra, 96 Cal.App.4th at p.
    1455.) The question before the Supreme Court was whether a clause
    stating that reunification services must be provided if the parent has
    made a reasonable effort to treat the problems that led to the child ’s
    removal was applicable to subpart (A) of former subdivision (b)(10),
    which stated that reunification services need not be provided where
    past efforts at reunification proved unsuccessful after removal of
    another child, and where parental rights to another child have been
    severed. (Id. at pp. 1455–1457.) After the Supreme Court concluded
    that it was not applicable, the Legislature introduced an amendment
    that “restructured the clauses of subdivision (b)(10), creating a new
    subparagraph (b)(11), to clarify that the ‘no reasonable effort’ clause
    did apply” to subpart (A). (Id. at p. 1457.)
    61
    retrospective change. [Citation.] Whether a statute should apply
    retrospectively or only prospectively is, in the first instance, a
    policy question for the legislative body enacting the statute.
    [Citation.] Thus, where a statute provides that it clarifies or
    declares existing law, “[i]t is obvious that such a provision is
    indicative of a legislative intent that the amendment apply to all
    existing causes of action from the date of its enactment. In
    accordance with the general rules of statutory construction, we
    must give effect to this intention unless there is some
    constitutional objection thereto.” [Citations.]’ [Citation.]”
    (Renee J., at pp. 1460–1461, italics added.)
    The court in Renee J. observed that “the Legislature acted
    swiftly to clarify an existing law in the wake of court
    interpretation . . . at the express invitation of the Supreme Court,
    which declared the prior law to be ambiguous” and that the
    Senate Rules Committee “explain[ed] that the amendment of the
    statute [was] necessary merely to rectify a perceived problem
    with the prior version, and not the product of any desire to take
    the law in a new direction.” (Renee J., supra, 96 Cal.App.4th at
    pp. 1461–1462.) Thus, “it was the intent of the Legislature to give
    its clarification retroactive effect” and “the Legislature’s
    clarification . . . is properly applied to all open cases, including
    this one.” (Id. at pp. 1461, 1463.) Accordingly, “the new
    legislation should have been applied, and properly overrode the
    effect of the Supreme Court’s decision, which would otherwise
    have been law of the case.” (Id. at p. 1463.)
    Here, unlike in Renee J., the 2016 legislation imposed a
    new MCO tax on HCSPs for a period of three years and was
    clearly intended to take the law in a new direction to comply with
    new federal funding requirements. The statutory language did
    62
    not provide or declare that the imposition of the new MCO tax
    demonstrated its understanding that HCSPs under the Knox-
    Keene Act are not insurers for any purposes, including in
    preceding periods, and the legislative history did not discuss
    Myers I or the appropriate taxation of HCSPs when explaining
    the purpose of the legislation.18 In the absence of any of the facts
    that supported overriding the law of the case doctrine in Renee J.,
    we cannot conclude that Senate Bill No. X2-2 effected a change or
    clarification of the law such that Myers I is no longer binding.
    Myers also contends that the 2016 tax was one in a series
    of MCO taxes imposed by the Legislature and thus cannot
    constitute an intervening change in the law. Although the earlier
    legislation imposed MCO taxes on Medi-Cal plans and facilities,
    we agree that this history is relevant. For example, in 2009, the
    Legislature enacted Assembly Bill No. 1422, which temporarily
    extended the GPT to Medi-Cal managed care (MCMC) plans on
    an urgency basis. The Assembly concurrence to Senate
    amendments to the bill noted that “[m]ost MCMC plans are
    Knox-Keene licensed health plans[]” and that “Knox-Keene
    licensed plans do not pay the gross premiums tax.” (Concurrence
    in Senate Amendments of Assem. Bill No. 1422, Sept. 3, 2009,
    pp. 1–2, 5; Stats. 2009, ch. 157, p. 820.) As of 2009, the
    Legislature apparently understood that Knox-Keene Act licensed
    plans were not insurers for any purposes and were generally not
    subject to the GPT, notwithstanding its imposition of the GPT on
    certain plans. In 2013, the Legislature passed Senate Bill No. 78,
    18The legislative history refers to Myers I and subsequent proceedings
    in this matter only in the context of discussing litigation related to the
    legislation, and expresses no opinion about the decision in Myers I.
    63
    which set a sunset date for the GPT tax and imposed a sales and
    use tax on MCMCs from 2013 to 2016. (Stats. 2013, ch. 33, pp.
    1116–1117; Senate Third Reading of Sen. Bill No. 78 (2013–2014
    Reg. Sess.) as amended June 13, 2013, p. 1.) Thus, at the time
    that Myers I was decided, the Legislature had already passed
    legislation reflecting its understanding—repeated in a 2015
    report from the Assembly Public Health and Developmental
    Services Committee cited by Blue Cross—that Knox-Keene Act
    licensed plans are not insurers and thus “are not generally
    prohibited from other taxation.” (Assem. Pub. Health &
    Developmental Services Comm., Informational Hearing:
    Supporting and Enhancing California’s Medi-Cal and
    Developmental Services Programs (2015–2016 2d Ex. Sess.) July
    9, 2015, p. 9.) The 2016 MCO tax did not communicate this
    understanding in a more direct or explicit manner than the prior
    legislation, which further undermines the claim that it
    constitutes an intervening change or clarification of the law.
    In support of its arguments, Blue Shield cites a letter
    printed in the Assembly Daily Journal which stated that, through
    the 2016 MCO legislation, “the Legislature levied an MCO tax on
    licensed health care service plans, recognizing that health care
    service plans are not and have not been insurers as defined by
    Article XIII, §28 of the California Constitution and California
    Insurance Code §§ 22 and 23.” (Assem. Daily Journal, Sept. 14,
    2019, p. 3589.) Myers argues that the letter, written three years
    after Senate Bill No. X2-2 was signed into law, is not relevant to
    our determination of the Legislative intent behind the 2016 MCO
    tax. We agree.
    “When construing a statute, our task is to ascertain the
    intent of the Legislature as a whole. [Citation.] Generally, the
    64
    motive or understanding of an individual legislator is not
    properly received as evidence of that collective intent, even if that
    legislator was the author of the bill in question. [Citation.] Unless
    an individual legislator’s opinions regarding the purpose or
    meaning of the legislation were expressed in testimony or
    argument to either a house of the Legislature or one of its
    committees, there is no assurance that the rest of the Legislature
    even knew of, much less shared, those views. [Citation.]
    Moreover, if a legislator’s views were never expressed in a
    legislative forum, those legislators or other interested parties
    with differing opinions as to the bill’s meaning and scope had no
    opportunity to present their views in rebuttal. [Citation.]”
    (McDowell v. Watson (1997) 
    59 Cal.App.4th 1155
    , 1162, fn. 3.)
    The author of the letter voted on Senate Bill No. X2-2 in 2016 but
    was not the author of the bill. Even if he had been, his
    understanding of legislation passed three years prior is not
    determinative of the understanding of the Legislature as a whole
    as to the purpose of Senate Bill No. X2-2 absent any evidence
    that it was shared with the Legislature at that time.
    In sum, although the Legislature has the authority to pass
    legislation stating that Knox-Keene Act licensed plans are not
    insurers for any purposes, the 2016 MCO tax had the stated
    purpose of complying with federal funding requirements after the
    periods relevant to this litigation and contains no express
    statement that it was intended to be an exercise of that
    authority. Thus, no intervening clarification of existing law
    overrides the application of the law of the case doctrine.19
    19 Blue Cross and Blue Shield assert that, in the absence of a bright
    line test, HCSPs will continue to face uncertainty as to how they are
    65
    1.4.   Applying the Roddis standard to the undisputed
    facts, Real Parties in Interest are not insurers.
    Having concluded that Roddis supplies the applicable
    standard and that we remain bound by the Myers I court’s
    adoption of that standard under the law of the case doctrine, we
    now apply it to the undisputed facts before us.
    Pursuant to Roddis, we balance the direct service aspects of
    the businesses of Real Parties in Interest against the indemnity
    aspects and determine whether indemnity is a significant
    financial proportion of the business. (Roddis, supra, 68 Cal.2d at
    p. 683.) As discussed, indemnity exists where a member bears the
    risk of personal liability for medical services—i.e., the healthcare
    provider may seek payment directly from the member for medical
    services, who must then seek reimbursement from the HCSP. (Id.
    at p. 682.) “On the other hand, there is a strong social policy to
    encourage the services which health plans provide the public.”
    (Roddis, supra, 68 Cal.2d at p. 682.) Roddis indicates that the
    direct service offered by HCSPs is the provision of medical
    services to members for which they are not personally liable.
    (Ibid.)
    taxed. Considering that Real Parties in Interest have consistently paid
    over 90 percent of claims costs to in-network providers every year for
    approximately 10 years and members of their plans (including PPO
    plans) have strong incentives to seek care from in-network providers, it
    seems unlikely that the application of the Roddis balancing test would
    yield different results for the parties before us if further litigation
    arose. In any event, these concerns are best addressed by the
    Legislature, which may wish to enshrine in law its understanding that
    Knox-Keene Act licensed plans are not insurers for any purpose and
    are not subject to the GPT.
    66
    Further, although Myers I held that an HCSP’s regulatory
    status does not determine whether it is an insurer for tax
    purposes, we agree with the trial court that the Knox-Keene Act
    is a relevant consideration when considering the service functions
    of HCSPs. Health and Safety Code section 1342 demonstrates
    that the Legislature contemplated that HCSPs would provide
    various services, including “ensur[ing] the best possible health
    care for the public at the lowest possible cost by transferring the
    financial risk of health care from patients to providers.” (Health
    & Saf. Code, § 1342, subd. (d).) The regulatory scheme also
    imposes additional obligations on HCSPs, such as requiring the
    establishment and maintenance of provider networks (id.,
    § 1367.03), quality assurance monitoring processes (id., § 1370),
    and a system for submitting grievances (id., § 1368, subd. (a);
    Cal. Code Regs., tit. 28, § 1300.68).
    As HCSPs licensed under the Knox-Keene Act, the Health
    and Safety Code requires that the contracts between Real Parties
    in Interest and their providers state that a plan member will not
    be liable to the provider for amounts owed for services provided
    under the plan. (Health & Saf. Code, § 1379, subd. (a).) Even if a
    provider contract does not include this provision, the contracting
    provider is barred by law from attempting to collect the amounts
    owed under the plan from the member. (Id., subd. (b).) Because
    HCSP members bear no risk of personal liability for in-network
    care, only out-of-network care provided to members may be
    equated to “indemnity” under Roddis and Myers I.
    With this legal framework and regulatory background in
    mind, we turn to the undisputed evidence. We conclude that Real
    Parties in Interest are not insurers as a matter of law under the
    relevant standard.
    67
    1.4.1. Blue Cross
    Under Blue Cross’s HMO and PPO plans, members have
    access to a network of medical providers, hospitals, and other
    facilities that have contracted with Blue Cross to provide medical
    services to Blue Cross members at agreed upon rates. From 2005
    through 2016, Blue Cross’s contracts with these providers stated
    that members would not be required to pay providers for amounts
    owed to that provider by Blue Cross, other than copayments,
    coinsurance, or deductibles, even if Blue Cross fails to pay the
    provider. Thus, beyond copayments, coinsurance, or deductibles,20
    a member could never be liable for payments owed by Blue Cross
    to providers of in-network services. Between 2005 and 2016,
    between approximately 92 and 97 percent of Blue Cross’s claim
    costs (for both HMO and PPO plans) were for in-network claims,
    for which providers may only seek payment from Blue Cross.
    Thus, approximately 3 to 8 percent of its claim costs were
    indemnity payments for out of network services for which
    members were liable.
    Thus, a far greater proportion of Blue Cross’s business was
    devoted to direct service than to indemnity under Myers I and
    Roddis.21
    20Myers does not argue on appeal that member cost share payments
    constitute indemnity.
    21 Because we conclude that Blue Cross is not an insurer under Myers
    I, we do not address its alternative argument that the court should not
    subject it to retroactive liability under Myers I.
    68
    1.4.2. Blue Shield
    Under Blue Shield’s HMO plans, members must use
    contracted providers for nearly all care for the care to be covered
    under the plan. Although PPO members, unlike HMO members,
    may choose to obtain services from non-contracted (out-of-
    network) providers, PPO plans incentivize the use of contracted
    providers. Blue Shield’s provider contracts make clear that “in no
    event” may providers seek payment from plan members for
    covered services. Blue Shield’s HMO and PPO contracts with
    members also reflect the prohibition on member financial liability
    to contracted providers. Even under HMO plans, certain non-
    contracted providers are prohibited from attempting to collect
    from plan members, including out-of-network providers of
    emergency services or services authorized by the plan that cannot
    be rendered by a contracted provider, and continuity of care
    services when a contracted provider becomes non-contracted.
    During the relevant period of 2005 to June 2016, Blue
    Shield’s direct payments to contracted providers for which its
    members bore no financial responsibility beyond cost share
    payments ranged from 94 percent to 97 percent, and averaged 96
    percent, of its total payments for members’ health care. Blue
    Shield’s expenditures to non-contracted providers over the same
    period averaged 4 percent. Emergency services and other out-of-
    network services for which members are not liable are included in
    the 4 percent, meaning that the proportion of Blue Shield’s
    indemnity is likely lower, though the record does not identify
    what portion of this figure was for emergency services.
    Even if the indemnity payments made by Blue Shield were
    no lower than approximately 3 to 6 percent during the relevant
    period, the proportion of Blue Shield’s business that constituted
    69
    indemnity was not significant in comparison to the portion that
    comprised direct service.
    1.4.3. Kaiser
    Kaiser does not sell contracts that allow members to seek
    covered health care services from any provider or hospital of their
    choice, nor does Kaiser, with limited exceptions, promise to
    reimburse members for care they receive outside of Kaiser
    Permanente. During the relevant period, Kaiser members were
    responsible for copayment, coinsurance, and deductible amounts
    when they sought medical care from KFH and the Permanente
    Medical Groups. However, Kaiser’s EOCs during the relevant
    period stated: “Our contracts with Plan Providers provide that
    you are not liable for any amounts we owe.” To the extent that
    the out-of-network care was in connection with emergency
    services, Kaiser’s contracts with its members provide that
    members are not responsible for any amounts beyond cost share
    payments.
    Between 2007 and 2016, measured by dollars,
    approximately 1 to 4 percent of Kaiser’s healthcare expenses
    were paid to noncontracting providers or directly reimbursed to
    members. For the years 2007 through 2014, measured by discrete
    visits or consultations, approximately 95 percent of the covered
    health services provided to Kaiser members were rendered by
    Kaiser Permanente providers. In 2015, approximately 93.3
    percent of the covered health services provided to Kaiser
    members were rendered by Kaiser Permanente providers, and in
    2016, approximately 94.7 percent of the covered health services
    provided to Kaiser members were rendered by Kaiser
    Permanente providers.
    70
    Even disregarding that some portion of the out-of-network
    visits and expenses were likely for emergency services for which
    members are not personally liable, the portion of Kaiser’s
    business that constitutes indemnity was not significant compared
    to the direct service component.
    1.4.4. Health Net
    During the relevant period, Health Net’s EOCs for its
    commercial HMO plans provided that members must choose a
    physician group that would provide or authorize all medical care
    and that members were completely financially responsible for
    medical care that was not authorized by that physician group,
    with the exception of emergency medical care. Between 2007 and
    2016, Health Net’s commercial HMO provider contracts with in-
    network providers required the provider to agree not to bill or
    seek compensation or reimbursement from members for
    contracted services they provided to members, except for
    copayments, coinsurance, or deductibles.
    The annual approximate percentage of Health Net’s
    reported in-network expenses as compared to its total medical
    expenses for all Health Net product lines for the years 2007 to
    2016 was between 96 percent to 99 percent. In the combined
    period of 2007 through 2016, an average of approximately 98.6
    percent of Health Net’s reported health care expenses were made
    to in-network providers as defined by the DMHC. Thus, the
    portion of Health Net’s business that constituted indemnity
    (between approximately 1 and 4 percent) was not significant.
    71
    2.    The trial court did not abuse its discretion in
    sustaining the evidentiary objections of Real Parties in
    Interest.
    2.1.   Standard of Review
    Myers asserts that there is a split of authority in California
    as to the appropriate standard of review of evidentiary rulings.
    He contends that Pipitone v. Williams (2016) 
    244 Cal.App.4th 1437
    , which in turn cites Reid v. Google, Inc. (2010) 
    50 Cal.4th 512
    , supports that the de novo standard should apply. However,
    in Reid, the Supreme Court applied the de novo standard of
    review to evidentiary objections on which the trial court had
    failed to rule, reasoning that “because there was no exercise of
    trial court discretion, the Court of Appeal had no occasion to
    determine whether the trial court abused it.” (Reid, at p. 535.)
    The Supreme Court expressly declined to consider “whether a
    trial court’s rulings on evidentiary objections based on papers
    alone in summary judgment proceedings are reviewed for abuse
    of discretion or reviewed de novo.” (Ibid.) “[T]he weight of
    authority since Reid supports application of the abuse of
    discretion standard. Cases considering this question and applying
    the abuse of discretion standard after Reid have been published
    by the First District, Second District, Third District, Fourth
    District (Division One), Fifth District, and Sixth District— in
    other words, essentially every district of the appellate courts of
    the State of California . . . .” (Doe v. SoftwareONE, Inc. (2022) 
    85 Cal.App.5th 98
    , 103, fn. omitted; LAOSD Asbestos Cases (2020)
    
    44 Cal.App.5th 475
    , 485 [“The weight of authority in this state is
    that we apply an abuse of discretion standard when we review
    trial court evidentiary rulings.”].)
    72
    As courts have observed, “application of the abuse of
    discretion standard is eminently sensible in light of the practical
    realities of evidentiary objections in summary judgment
    proceedings.” (Doe v. SoftwareONE, Inc., supra, 85 Cal.App.5th
    at p. 103; cf. Ducksworth v. Tri-Modal Distrib. Servs. (2020) 
    47 Cal.App.5th 532
    , 544, revd. on other grounds in Pollock v. Tri-
    Modal Distribution Services, Inc. (2021) 
    11 Cal.5th 918
    .) Given
    the large number of evidentiary objections that frequently
    accompany summary judgment motions, “trial courts typically
    rule on evidentiary objections in summary fashion, which often
    prevents us from determining the precise nature (i.e., principally
    legal or factual) of the trial court’s ruling. And rulings on
    evidentiary objections often ‘involve trial courts making
    qualitative and sometimes equitable determinations,’ which are
    the sort of decisions we typically review for abuse of discretion.
    [Citation.]” (Doe, at p. 103; cf. Ducksworth, at p. 544 [“Because of
    the daunting complexity, volume, and pace of [the trial court’s]
    decisionmaking task, the latitude implied by the abuse-of-
    discretion standard thus does make ‘great sense.’ [Citation.]”].)
    We therefore follow the weight of authority and apply the
    abuse of discretion standard. Under this standard, “[a]n
    ‘erroneous evidentiary ruling requires reversal only if “there is a
    reasonable probability that a result more favorable to the
    appealing party would have been reached in the absence of the
    error.” [Citation.]’ [Citation.” (Daimler Trucks North America
    LLC v. Superior Court (2022) 
    80 Cal.App.5th 946
    , 960.)
    2.2.   The court did not err in sustaining the
    evidentiary objections of Real Parties in Interest.
    The trial court sustained multiple evidentiary objections to
    the Duncan declarations, primarily on relevance and foundation
    73
    grounds. These objections related to statements in the Duncan
    declarations that Real Parties in Interest employ actuaries and
    engage in actuarial analyses, make the majority of their
    payments to providers on a fee-for-service basis, hold reserves
    and free capital, assume and spread risk, file the same
    documents as insurers do, and thus that Real Parties in Interest
    operate as insurers, among others.
    As discussed above, the Roddis standard does not require a
    court to consider whether an HCSP engages in risk pooling or
    spreading, whether its payments to providers are fee-for-service
    or capitated, or whether it otherwise operates in a manner
    comparable to insurers. Thus, the trial court did not abuse its
    discretion in concluding that the portions of the Duncan
    declarations to which Real Parties in Interest objected were
    irrelevant.
    Evidence that Health Net and Blue Cross received payouts
    as insurers under the federal Affordable Care Act was also
    properly excluded. The trial court did not abuse its discretion in
    concluding that such payments are immaterial, as “the question
    of whether a law applies to HCSPs as well as insurers depends on
    the purpose of the law” and is not determined by labels that may
    apply to Real Parties in Interest in different contexts. This
    determination is consistent with Myers I, which instructed that
    courts must “ ‘look beyond the formal labels the parties have
    affixed to their transactions’ ” and instead “ ‘discern the true
    economic substance’ of the arrangement.” (Myers I, supra, 240
    Cal.App.4th at p. 741, quoting Metropolitan Life, supra, 32 Cal.3d
    at pp. 656–657.) The standard adopted in Myers I to determine
    the true economic substance of an HCSP’s business does not
    74
    require a court to consider whether the HCSP is classified as an
    insurer by the federal government.
    Finally, the trial court did not abuse its discretion when it
    excluded evidence that PPO plans offered by insurance
    companies affiliated with Blue Cross and Blue Shield are similar
    to the PPO plans offered by Blue Cross and Blue Shield and that
    their websites and actuarial certificates refer to both as insurers.
    Whether HCSPs and related insurers offer similar plans or fulfill
    similar functions has no bearing under the Roddis standard.
    Moreover, as discussed, whether Blue Cross and Blue Shield
    refer to their PPO plans as insurance in certain contexts is a
    question of labeling, not economic substance, and is therefore of
    no relevance under Myers I.
    In sum, the court did not abuse its discretion in excluding
    evidence that had no bearing on the application of the controlling
    legal standard. For the same reason, there is no reasonable
    probability that Myers would have reached a more favorable
    result had this evidence been admitted.
