    PEARCE, Justice:
    ¶1     Appellant Ann V. Maak appeals from the district court’s
    order granting IHC Health Services, Inc.’s (IHC) motion to
    decertify a class and denying Maak’s motion to amend the class
    definition. Maak contends the district court abused its discretion
    in so ruling. Maak also contends that the district court erred in
    1. Justice John A. Pearce began his work on this case as a
    member of the Utah Court of Appeals. He became a member of
    the Utah Supreme Court thereafter and completed his work on
    the case sitting by special assignment as authorized by law. See
    generally Utah R. Jud. Admin. 3-108(3).
    Maak v. IHC Health Services
    determining that IHC had not waived its counterclaims against
    class members. We are unable to discern the basis for the district
    court’s conclusion that IHC did not waive its counterclaims. We
    therefore remand for the entry of a new decision on that issue—
    one that is accompanied by a development of the factual record
    and appropriate legal analysis. Because the district court relied
    on the viability of IHC’s counterclaims in its decision to grant
    IHC’s motion to decertify the class, we vacate the court’s
    decertification decision for further consideration in light of the
    district court’s resolution, on remand, of Maak’s challenge to
    IHC’s counterclaims. We also conclude that the district court’s
    order does not permit us to determine whether it properly acted
    within its discretion in denying Maak’s motion to amend the
    class definition, and we vacate that decision as well. We
    therefore remand the case to the district court for further
    consideration.
    BACKGROUND2
    ¶2     Maak sued IHC, arguing that IHC had engaged in
    ‚fraudulent and improper billing practices.‛ Maak alleged that
    IHC improperly overcharged her for medical care she had
    received and that the overcharges resulted from IHC’s regular
    and systematic billing practices.
    ¶3      After Maak received treatment at LDS Hospital—an IHC
    facility—she received a statement of itemized charges totaling
    $11,396.11. Regence Blue Cross Blue Shield (Regence) provided
    health insurance to Maak at the time of her treatment. Regence
    reimbursed IHC $12,310.36 for Maak’s treatment, an amount that

    found in Maak v. IHC Health Servs., Inc.,

    2016 UT App 73
    Maak v. IHC Health Services
    exceeded the itemized charges. Regence paid the greater amount
    because, ‚[p]ursuant to a contract between IHC and Regence, all
    medical procedures performed at LDS Hospital are classified in
    a Diagnostic Related Group (DRG), which Regence agrees to
    reimburse, at a predetermined fixed rate, without regard to the
    actual costs LDS Hospital incurs for the services.‛ Maak v. IHC
    Health Servs., Inc., 
    2007 UT App 244
    , ¶ 3, 
    166 P.3d 631
    . In
    addition to the payment it received from Regence, IHC billed
    Maak an additional $986.63 ‚based on Maak’s twenty percent
    coinsurance obligation‛ her insurance contract with Regence
    imposed. 
    Id. ¶ 4
    .
    ¶4     During discovery, an IHC employee explained the billing
    practices IHC employed when an insurer had agreed to
    reimburse IHC a fixed price for a medical procedure based on a
    DRG classification. In addition to reimbursing IHC based upon
    the DRG classification, the insurance company would
    ‚determine*+ the patient’s liability based on the benefits of *the
    patient’s] particular [insurance] policy.‛ The insurance company
    would then inform IHC of any responsibility for payment that
    the patient might owe under the insurer’s agreement with the
    patient. For example, the contract between the insurer and
    insured might impose a coinsurance obligation on the patient.3
    ¶5     IHC would then combine the payment it received from
    the insurance company and ‚the amount due from the patient.‛
    If the combined amount did not match the original itemized
    charges of the insured’s medical procedure, IHC’s system would
    automatically make an adjustment to the account, which IHC
    terms a ‚contractual adjustment.‛ The contractual adjustment
    3. By way of example, Maak’s contract with Regence required
    her to pay twenty percent of the covered procedure, subject to an
    annual cap, as her coinsurance obligation. Maak v. IHC Health
    Servs., Inc., 
    2007 UT App 244
    , ¶ 4 & n.1, 
    166 P.3d 631
    .
    20140003-CA                     3                
    2016 UT App 73
    Maak v. IHC Health Services
    was designed ‚to bring the charges in line with the terms of the
    reimbursement contract‛ between IHC and Regence. In cases
    where the sum of the amount IHC received from the insurer and
    the patient’s responsibility exceeded the itemized charges, the
    contractual adjustment would be an additional amount posted to
    the patient’s account. In cases where the sum of the insurer’s
    payment and the patient’s responsibility was less than the
    itemized charges, the contractual adjustment would reduce the
    patient’s original itemized charges. Thus, where the insurer and
    IHC agreed to reimbursement based upon DRG classifications,
    IHC’s billing system would adjust a patient’s account so that the
    amount ultimately billed equaled the combined amount of the
    DRG reimbursement from the insurer and the amount of the
    patient’s responsibility under the patient’s insurance contract.
    This created a system where in some cases a patient and her
    insurance company would be charged more than the sum total
    of the patient’s itemized charges and in other cases they would
    be charged less.
    ¶6     In this instance, IHC billed Maak for $986.63, her patient
    responsibility under her contract with Regence. Maak initially
    resisted IHC’s efforts to collect but eventually paid the full
    amount. Maak continued to dispute IHC’s ability to collect the
    coinsurance because ‚IHC already had been more than fully
    compensated by Regence for the hospital charges incurred on
    her behalf.‛ 
    Id. ¶ 4
    . Maak then sued IHC, on behalf of herself and
    a class of similarly situated patients for, among other causes of
    action, fraud and breach of contract. See 
    id.
     The district court
    granted summary judgment to IHC on all of Maak’s claims.
    ¶7     Maak appealed to this court and argued, among other
    things, that the district court erred in concluding that IHC’s
    efforts to bill Maak in excess of the itemized charges did not
    breach Maak’s contracts with IHC and Regence. 
    Id. ¶ 7
    . We
    agreed with Maak and reversed the district court’s grant of
    summary judgment on Maak’s breach of contract claim.

    2016 UT App 73
    Maak v. IHC Health Services
    We held ‚that as a matter of contract law, IHC could not bill
    Maak for medical services after it had collected the full amount
    chargeable for those services from Maak’s insurer.‛ 
    Id.
     We then
    remanded the matter for a determination of whether Maak could
    satisfy the class certification requirements contained in rule 23 of
    the Utah Rules of Civil Procedure. 
    Id. ¶ 32
    ; see also Utah R. Civ.
    P. 23(a)–(b).
    ¶8     On remand, the district court conditionally certified the
    case as a class action. The court determined that all elements of
    rule 23 were conditionally satisfied, and certified a class of:
    All patients who at any time after or within six
    years prior to May 27, 2003 received medical
    services from an IHC-owned or operated medical
    facility or an IHC health-care provider of any kind
    and then were billed for amounts that, when
    collected, resulted in IHC receiving in combination
    from the patient’s insurance company and the
    patient more than actual charges. Medicare
    patients are excluded.
    Although it certified the class, the district court questioned
    whether ‚the class should include only individuals who were
    insured by Regence, or alternatively, patients, regardless of
    insurer, who were billed for amounts that resulted in IHC
    receiving from the insurer and patient more than the actual
    expenses.‛ The court ultimately concluded, ‚Unless a patient’s
    insurance company’s contract with the patient grants IHC the
    right or obligation to collect a co-payment from a patient, the
    identity of the insurer is irrelevant to the fact that IHC breached
    its contract with the patient . . . .‛ Because the court certified the
    class in the midst of discovery, it had insufficient information to
    determine if other insurance companies’ contracts were similar
    to Regence’s. Thus, the court ‚conditionally include*d+ class
    members not limited to Regence insureds.‛ The court cautioned
    20140003-CA                      5                 
    2016 UT App 73
    Maak v. IHC Health Services
    that the ‚class definition is conditional‛ and noted that rule 23
    ‚permits an order on class certification to be altered or amended
    at any time before a decision on the merits.‛ See Utah R. Civ. P.
    23(c)(1).
    ¶9     Following class certification, the parties developed a two-
    stage discovery process to identify class members, designated as
    ‚Tier 1‛ and ‚Tier 2.‛ In the first stage, IHC initiated an
    automated review of its records ‚to identify instances when *it+
    may have collected more than what was listed on‛ the patient’s
    itemized statement. In the second stage, IHC organized ‚a
    manual audit of [its] patient files to identify instances in which
    IHC collected more than the itemized statements.‛ The district
    court noted that this process identified 41,849 instances where
    IHC collected money in excess of an itemized statement. It also
    noted that the overcharges totaled roughly $9,500,000, with an
    average of more than $220 per instance.
    ¶10 In addition to collecting data regarding its billing of
    patients for more than their itemized charges, IHC identified
    instances when its billing practices led to ‚shortfalls between
    what patients and their insurers paid and what was listed on the
    itemized statements.‛ IHC referred to this data as ‚Tier 1.5,‛ and
    contended that approximately ninety percent of the class
    members had at some point paid less than their itemized
    statements. IHC then asserted counterclaims against Maak and
    the class members for those alleged shortfalls. IHC estimated
    that aggregate total damages for these counterclaims amounted
    to $220,000,000, with an average of $6,822 per instance.
    ¶11 Maak moved for summary judgment on IHC’s
    counterclaims. Maak argued that IHC had no valid
    counterclaims for the so-called ‚shortfall amounts‛ and that
    even if it did, the claims failed because IHC had waived its right
    to bill and collect any ‚shortfall[s].‛ IHC opposed summary
    judgment, arguing that its counterclaims were valid and that it
    20140003-CA                     6                
    2016 UT App 73
    Maak v. IHC Health Services
    had not waived its right to collect the shortfall amounts.
    Approximately six months later, Maak filed a notice to submit
    her summary judgment motion for decision. There is no
    indication in the record that the district court ever explicitly
    ruled on Maak’s motion.
    ¶12 IHC then moved to decertify the class. IHC contended
    that decertification was appropriate because individual inquiry
    into each ‚patient’s account and . . . insurance contract‛ was
    necessary prior to resolving the case. IHC also maintained that in
    thousands of cases, ‚critical documents such as *a patient’s+
    Explanation[] of Benefits‛ were unavailable and it could not
    determine in those cases ‚why [it] collected more than the
    Itemized Statement when patient and insurer payments are
    combined.‛ IHC argued that prior to the class adjudication, ‚an
    exhaustive analysis and adjudication of the individual facts of
    each and every case is necessary,‛ which would lead to
    ‚thousands of mini-trials that are anathema to class action
    procedure.‛
    ¶13 IHC also claimed that, during discovery, it found
    evidence that many of the class members’ insurance contracts
    were materially different from Maak’s. In some instances, IHC
    insisted it could ‚conclusively demonstrate‛ that it was
    authorized to collect the overbilled amounts from the patient as
    a third-party beneficiary to the patient’s insurance contract. In
    others, it argued that class members should be excluded
    ‚because their claims, if any, are governed by ERISA[4] or
    precluded by arbitration clauses [in the insurance contracts+.‛ In
    addition, IHC believed many class members would likely be
    ‚exposed to claims from their insurers if the *district court+
    4. The federal Employee Retirement Income Security Act
    (ERISA) creates standards and ‚safeguards‛ for certain
    employee benefit plans. See 29 U.S.C. § 1001 (2012).
    20140003-CA                     7                
    2016 UT App 73
    Maak v. IHC Health Services
    rule[d] that patients are not responsible to pay [IHC] for the
    mandatory coinsurance, deductibles, and copayments‛ provided
    in their insurance contracts.
    ¶14 The court’s ability to resolve the dispute on a class-wide
    basis was also undercut, IHC argued, by its counterclaims,
    which would require additional individualized adjudication and
    would create ‚misaligned‛ interests within the class due to
    many class members likely owing more ‚than they could ever
    expect to recover‛ from IHC. For all these reasons, IHC
    requested decertification of the class.
    ¶15 Maak opposed IHC’s motion to decertify the class, but
    also moved to amend the class definition. Maak argued that
    despite the complex nature of the case, a ‚common question‛
    bound the class together—the unlawfulness of IHC’s practice of
    overcharging patients after having been fully reimbursed by
    their medical insurer—and that there was ‚more than a
    sufficient legal and evidentiary basis‛ to justify both a rejection
    of IHC’s proposed decertification and a grant of Maak’s request
    to amend the class definition.
    ¶16 Maak argued that rather than decertify the class, the court
    should amend the class to only include those who, according to
    the Tier 2 review, were overbilled ‚in the exact same way as
    Maak, as the result of a flat-fee [DRG reimbursement method]
    between IHC and the commercial insurer and the systematic
    IHC overbilling practices.‛ Essentially, Maak argued that her
    proposed amended class met rule 23’s class certification
    requirements for three reasons: (1) because this court held IHC’s
    overcharging of Maak to be an unlawful breach of contract; (2)
    because all members of the proposed class had contracts with
    their insurers that were similar to Maak’s, making IHC’s
    overcharging unlawful in those instances; and (3) because any
    required individualized inquiry would be outweighed by the
    potential for the case’s ‚class-wide resolution in a single stroke.‛
    20140003-CA                     8                 
    2016 UT App 73
    Maak v. IHC Health Services
    ¶17   Maak proposed the class be amended to include:
    All patients who, at any time after or within six
    years prior to May 27, 2003, were insured by a
    commercial insurance company that had a [DRG],
    fee schedule, and/or per diem reimbursement
    agreement with IHC; received covered medical
    services from an IHC medical facility or other IHC
    health-care provider; and then were billed by IHC
    for those services in an amount that, when
    collected, resulted in IHC receiving a combined
    amount, from the commercial insurer’s payments
    and the patient’s subsequent payments for those
    services, that was more than IHC’s itemized
    charges for those services.
    This refined definition, Maak contended, would remedy the
    ‚infirmities alleged by IHC,‛ while still holding IHC ‚to the
    results of the two-tiered process that it proposed, co-designed,
    and completed.‛
    ¶18 Maak also contended that class members should be
    included regardless of whether the member’s Explanation of
    Benefits document (EOB) could be found because IHC had
    destroyed many of those documents after the case was filed. In
    Maak’s view, IHC should not be allowed to argue that class
    membership would be difficult to determine for those who no
    longer have an EOB, because the EOBs were ‚solely in IHC’s
    control and were destroyed by IHC, most of them after [the case]
    was filed.‛5 For that reason, Maak claimed, the district court
    5. To support this contention Maak maintained, ‚IHC has
    admitted that it has ‘archived,’ ‘purged,’ and ‘not retained’ the
    EOBs, including as late as July 2007, four years after Maak filed
    *suit+.‛
    20140003-CA                    9                 
    2016 UT App 73
    Maak v. IHC Health Services
    ‚should rule that all inferences from the missing EOBs . . . be
    drawn in favor of the Class‛ based on the doctrine of spoliation
    of evidence, and that even class members without EOBs should
    be considered properly included in the class. Alternatively,
    Maak contended, ‚[E]ven if the Court were to exclude claims
    with missing EOBs . . . a group of thousands of patients with
    millions of dollars of damages would remain appropriate for
    class adjudication.‛
    ¶19 Addressing IHC’s counterclaims, Maak argued that the
    counterclaims would not impede class-wide adjudication
    because IHC had ‚intentionally and unequivocally‛ waived
    those claims by voluntarily collecting less than the amounts it
    had sent to the patients in their itemized charges. Maak also
    argued that IHC’s counterclaims were not compulsory and
    therefore asked that they ‚be dealt with in a separate suit rather
    than being allowed to defeat the Class.‛
    ¶20 Following extensive briefing, the district court granted
    IHC’s motion to decertify the class and denied Maak’s motion to
    amend the class definition. The court found that although IHC
    had collected amounts from class members in excess of their
    respective itemized charges, ‚the reasons for *the overpayments+
    are many and are not necessarily the result of a systematic
    billing practice in violation of the *parties’+ contractual
    relationships.‛ The court concluded, ‚*T+here are *no longer+
    questions of law or fact common to the class and . . . the claims
    or defenses of the representative parties are [no longer] typical of
    the claims or defenses of the class.‛
    ¶21 The court next concluded that it was ‚not feasible to
    determine on a class-wide basis whether individuals [were] even
    appropriately included in the conditional class, and whether
    liability exists.‛ The court highlighted several factual scenarios
    that would exclude some members from the class, including:
    20140003-CA                     10                
    2016 UT App 73
    Maak v. IHC Health Services
    1) where the combined payments from the patient
    and insurer do not exceed IHC’s itemized charges;
    2) where the circumstances of the individual case
    are inconsistent with the conditional class
    definition; 3) where the patient did not experience
    a loss; and 4) where IHC was not at fault for the
    overpayment.
    ¶22 The court determined that ‚there can be no uniform
    alignment of interests, and no ability to generalize causation,
    injury, and liability‛ when thousands of class members were
    ‚subject to counterclaims that might involve widely varying
    degrees of damages.‛ The court was also ‚concerned about the
    potential conflict of interest between [Maak] and class members
    who might be subject to those counterclaims.‛ It concluded,
    ‚Those potential counterclaims are no longer speculative, were
    not waived by IHC, and warrant decertification.‛
    ¶23 Finally, the district court addressed Maak’s proposed
    amended class definition. It reasoned, ‚*T+he re-defined class
    essentially asks the Court to adopt an adverse [inference] against
    IHC, which is not appropriate, and in any event, the problem
    remains that establishing causation and damages would still
    require individualized adjudications to determine the facts of
    each specific case.‛
    ¶24 The district court concluded that it had ‚no alternative
    but to decertify the conditionally certified class‛ and to deny
    Maak’s motion to amend the class definition. Maak appeals.
    ISSUES AND STANDARDS OF REVIEW
    ¶25 Maak first contends that the district court erred as a
    matter of law in holding that IHC had not waived its
    counterclaims. ‚*W]hether the [district] court employed the
    proper standard of [contractual] waiver presents a legal question
    20140003-CA                    11                
    2016 UT App 73

    which is reviewed for correctness, but the actions or events
    allegedly supporting waiver are factual in nature and should be

    ¶26 Maak next contends that the district court abused its
    discretion in granting IHC’s motion to decertify the class. The

    ANALYSIS
    ¶28 Maak and IHC agree that we review the district court’s
    class-decertification decision for abuse of discretion. They
    disagree, however, over when a district court abuses that
    discretion. There exists little Utah case law addressing motions
    to decertify. Maak attempts to fill this void with cases from
    outside of our jurisdiction; Maak argues that these cases suggest
    that once a district court has certified a class, it has an obligation
    to take all steps necessary to try to maintain the viability of that
    class. See, e.g., Woe v. Cuomo, 
    729 F.2d 96
    , 107 (2d Cir. 1984) (‚*I+t
    is an extreme step to dismiss a suit simply by decertifying a
    class, where a ‘potentially proper class’ exists and can easily be
    created.‛); Chisolm v. TransSouth Fin. Corp., 
    194 F.R.D. 538
    , 554
    (E.D. Va. 2000) (‚Prior to decertification, the Court must consider
    all options available to render the case manageable.‛). IHC
    points to decisions highlighting the considerable discretion
    afforded to district courts in managing class action litigation. See,
    e.g., Shook v. Board of County Comm’rs of El Paso, 
    543 F.3d 597
    , 603
    (10th Cir. 2008) (‚When applying an abuse of discretion standard
    of review, we necessarily recognize that there may be no single
    right answer to the question at hand, but a range of possible
    outcomes sustainable on the law and facts, and we will defer to
    the district court’s judgment so long as it falls within the realm
    of these rationally available choices.‛ (citation and internal
    quotation marks omitted)).
    ¶29 The Utah Supreme Court has explained that ‚*o]ne reason
    . . . district courts are allowed such broad discretion is that rule
    23(c)(1) of the Utah Rules of Civil Procedure grants the district
    court the ability to alter or amend the order of class certification
    20140003-CA                      13                
    2016 UT App 73
    Maak v. IHC Health Services
    before the decision on the merits.‛ Jaques, 
    2010 UT 54
    , ¶ 35. The
    court reasoned, ‚[I]f it becomes necessary, the class action may
    be amended to contain subclasses to meet the factual pattern of
    the case.‛6 
    Id.
     And ‚if it is found by the district court that the
    individual transactions of the class members are too varied to be
    categorized into subclasses, it is within the discretion of the
    [district] court to decertify the class.‛ 
    Id.
     Nothing in the supreme
    court’s analysis of rule 23 supports the hard-and-fast rule Maak
    advocates—that a district court must take all steps necessary to
    preserve the class action. Indeed, the plain language of rule 23
    provides that a case ‚may be maintained as a class action‛ if the
    court finds that the plaintiff has satisfied certain requirements.
    Utah R. Civ. P. 23(a)–(b) (emphasis added). Likewise, the
    supreme court has consistently referred to what the court may do
    and not what it shall do in response to challenges to class
    certification or composition. See Jaques, 
    2010 UT 54
    , ¶ 35; see also
    Richardson v. Arizona Fuels Corp., 
    614 P.2d 636
    , 639 (Utah 1980)
    (‚If the criteria of Rule 23 are complied with, it is within the
    sound discretion of the district court to determine whether a
    suit, or some of the issues in a lawsuit, should proceed as a class
    action.‛).
    ¶30 The breadth of that discretion does not, however, mean
    that the district court can deny a motion to certify without
    carefully considering the motion and setting forth the reasons
    underlying the exercise of its discretion. See Richardson, 614 P.2d
    at 639 (‚It is the duty of the district court to apply carefully the
    criteria set forth in Rule 23(a) and (b) to the facts of the case to
    6. Utah Rule of Civil Procedure 23(c)(4) provides, ‚When
    appropriate (A) an action may be brought or maintained as a
    class action with respect to particular issues, or (B) a class may
    be divided into subclasses and each subclass treated as a class,
    and the provisions of this rule shall then be construed and
    applied accordingly.‛ Utah R. Civ. P. 23(c)(4).

    court has an independent obligation to conduct a ‘rigorous
    analysis’ before concluding that Rule 23’s requirements have
    been satisfied.‛ (citation omitted)). The district court must also
    create an order sufficient to allow a reviewing court to
    understand the basis of its reasoning before the reviewing court
    can afford deference to the district court’s decision. See
    Richardson, 614 P.2d at 639 (holding, among other things, that the
    district court committed reversible error by certifying a class
    action when ‚neither the memorandum decision nor the order of
    the district court does any more than recite that the suit may be
    maintained as a class action‛); see also Vega v. T-Mobile USA, Inc.,
    
    564 F.3d 1256
    , 1275–80 (11th Cir. 2009) (holding that the district
    court abused its discretion by failing to conduct a sufficient
    typicality and superiority analysis of the class certified by the
    court, and criticizing the court’s failure to ‚even attempt to
    describe whether and how [the representative party’s+ claims are
    typical of the remaining class that *the court+ actually certified‛);
    In re Hydrogen Peroxide Antitrust Litig., 
    552 F.3d 305
    , 321–23, 327

    order and remanding for further proceedings because, among
    other things, the court failed to undertake a sufficient analysis);
    State ex rel. Chemtall Inc. v. Madden,

    , 782–83 (W.
    Va. 2004) (concluding that a circuit court committed reversible
    error by failing to provide sufficient analysis and factual
    findings to support its class-certification decision).
    ¶31 The same considerations apply to a class-decertification
    motion. A district court must carefully analyze whether the
    certified class continues to meet rule 23’s requirements.
    Richardson, 614 P.2d at 639. The rigorous analysis demanded by
    rule 23 requires the district court to ‚do more than offer brief
    and conclusory statements establishing the Rule 23
    prerequisites.‛ See Slaven v. BP Am., Inc., 
    190 F.R.D. 649
    , 651
    20140003-CA                     15                 
    2016 UT App 73
    Maak v. IHC Health Services
    (C.D. Cal. 2000). Rather a district court ‚must offer written
    reasons supporting its decision to maintain class certification, or,
    alternatively, to decertify the action.‛ 
    Id. ¶32
     Indeed, the need for a thorough explanation of the district
    court’s reasoning becomes even more pronounced on a motion
    to decertify because the district court does not write on a blank
    slate. ‚Once a class is certified, the parties can be expected to rely
    on it and conduct discovery, prepare for trial, and engage in
    settlement discussions on the assumption that in the normal
    course of events it will not be altered except for good cause.‛
    O'Connor v. Boeing N. Am., Inc., 
    197 F.R.D. 404
    , 409–10 (C.D. Cal.
    2000) (citation and internal quotation marks omitted). This
    reliance entitles the parties to a careful analysis of the rule 23
    requirements and a reasoned explanation of why the case can no
    longer be maintained as a class action. Moreover, a reviewing
    court needs the benefit of the district court’s analysis to evaluate
    whether the court has properly exercised its discretion.
    ¶33 In the context of a motion to amend the class definition,
    rule 23 explicitly recognizes that a class-certification order ‚may
    be altered or amended before the decision on the merits.‛ Utah
    R. Civ. P. 23(c)(1). Although we find no support in Utah law for
    Maak’s argument that the district court must take all steps
    necessary to preserve a certified class, our rules of civil
    procedure and supreme court case law permit the district court
    to consider whether the original class should be divided into
    subclasses. See Utah R. Civ. P. 23(c)(4); Jaques v. Midway Auto
    Plaza, Inc., 
    2010 UT 54
    , ¶ 35, 
    240 P.3d 769
    . Further, when
    presented with a motion to amend a class, the district court must
    carefully analyze the proposed amended class under rule 23’s
    requirements and clearly articulate its reasoning as to why the
    amended class either would or would not satisfy rule 23. See
    Richardson, 614 P.2d at 639; see also In re Motor Fuel Temperature
    Sales Practices Litig., 
    279 F.R.D. 598
    , 603–05 (D. Kan. 2012)
    (reviewing a motion to amend a class by comparing the then-
    20140003-CA                      16

    Maak v. IHC Health Services
    current class definition with the plaintiff’s proposed class
    definition).
    I. IHC’s Counterclaims Against Class Members
    ¶34 Against this backdrop, we examine whether the district
    court properly exercised its discretion in decertifying the class.
    Among Maak’s many arguments aimed at demonstrating that
    the district court abused its discretion, she contends that the
    court improperly relied on the purported difficulties IHC’s
    counterclaims presented for class treatment.
    ¶35 Maak correctly asserts that IHC’s counterclaims played a
    role in the district court’s decision to decertify the class. IHC’s
    counterclaims are, in essence, its attempt to collect the full
    amount of a patient’s itemized charges in those instances where
    its agreement with an insurer led it to collect less than the
    patient’s full itemized charge for the applicable medical
    procedures. See supra ¶¶ 3–5. The district court concluded that
    ‚with thousands of people identified in the Tier 2 analysis
    subject to counterclaims that might involve widely varying
    degrees of damages, there can be no uniform alignment of
    interests, and no ability to generalize causation, injury, and
    liability.‛ The court was also concerned with the counterclaims’
    potential to create a conflict of interest between Maak and other
    class members who may or may not be subject to suit based on
    the counterclaims.
    ¶36 Maak argues that the district court abused its discretion in
    considering the counterclaims as part of its decertification
    calculus because IHC had waived its counterclaims as a matter
    of law. We cannot determine on the record before us whether the
    district court correctly concluded that IHC had viable
    counterclaims that it had not waived.
    ¶37 ‚Waiver is an intentional relinquishment of a known
    right.‛ Meadow Valley Contractors, Inc. v. Department of Transp.,
    20140003-CA                    17

    Maak v. IHC Health Services
    
    2011 UT 35
    , ¶ 45, 
    266 P.3d 671
     (citation and internal quotation
    marks omitted). ‚Waiver of a contractual right occurs when a
    party to a contract intentionally acts in a manner inconsistent
    with its contractual rights, and, as a result, prejudice accrues to
    the opposing party or parties to the contract.‛ 
    Id.
     (citation and
    internal quotation marks omitted). ‚Waiver can be implied from
    conduct, such as making payments or accepting performance
    which does not comport with contractual requirements.‛
    Anderson v. Brinkerhoff, 
    756 P.2d 95
    , 98 (Utah Ct. App. 1988). For
    conduct to amount to an implied waiver of a contractual right, it
    must be intentional, Meadow Valley, 
    2011 UT 35
    , ¶ 45, and must
    be done ‚in a manner that is unambiguous,‛ McCleve Props., LLC

    2013 UT App 185
    , ¶ 10, 
    307 P.3d 650
     (citation and internal quotation marks omitted).
    ¶38 In the context of assessing whether a party has waived its
    rights under a contract, the supreme court has held that ‚each
    party has the burden to read and understand the terms of a
    contract before he or she affixes his or her signature to it.‛ ASC
    Utah, Inc. v. Wolf Mountain Resorts, L.C., 
    2010 UT 65
    , ¶ 28, 
    245 P.3d 184
     (citation and internal quotation marks omitted).
    ‚*S+ophisticated business parties are charged with knowledge of
    the terms of the contracts that they enter into.‛ 
    Id.
     Such parties to
    a contract are ‚‘not permitted to show that [they] did not know
    [a contract’s] terms, and in the absence of fraud or mistake [they]
    will be bound by all its provisions, even [if they have] not read
    the agreement and do not know its contents.’‛ McCleve, 
    2013 UT App 185
    , ¶ 12 (alterations in original) (quoting ASC Utah, Inc.,
    
    2010 UT 65
    , ¶ 28). Thus, a ‚party may not sign a contract and
    thereafter assert ignorance or failure to read the contract as a
    defense.‛ See John Call Eng’g, Inc. v. Manti City Corp., 
    743 P.2d 1205
    , 1208 (Utah 1987); see also McCleve, 
    2013 UT App 185
    , ¶ 12.
    Where a contract provides a discernible right and the party
    intentionally acts inconsistently with that right, the party may
    not later feign ignorance to avoid the waiver of that right. See

    , ¶¶ 12–13.

    2016 UT App 73
    Maak v. IHC Health Services
    ¶39     Maak points to IHC’s admission, ‚When we enter into
    those arrangements with the insurance plan, we’ve agreed to
    make an adjustment on the patient account and only hold the
    patient responsible for the deductible co-insurance or co-pay
    that’s determined by their plan benefit.‛ Maak also highlights
    IHC’s statement that ‚if the DRG payment was less than the
    itemized charges, and the patient’s payment still didn’t make up
    to the itemized charges, [the remaining amount due] would
    show as a credit.‛ Thus, ‚[w]hen the sum of the insurer’s DRG
    payment and the patient’s payments *was+ still less than the
    itemized charges,‛ IHC would amend the bill to ‚show*+ a
    current balance of zero‛ so long as the patient paid his or her co-
    payment or obligation under the contract with his or her
    insurance company.
    ¶40 Maak also argues that IHC’s right to collect the shortfall
    amounts—the basis of its counterclaims—‚did not suddenly
    spring into existence‛ with our statement in Maak v. IHC Health
    Services, Inc., 
    2007 UT App 244
    , 
    166 P.3d 631
    , that ‚when a health
    care provider has not been fully paid for its services, it can
    collect the difference from a patient pursuant to its contract with
    the patient.‛ See 
    id. ¶ 28
    . She contends that our statement was a
    mere recognition of existing law, not the creation of a new legal
    right, and thus, IHC had a right ‚to collect the shortfall
    amounts . . . at the time *it+ billed the patients.‛
    ¶41 Finally, Maak asks us to infer that ‚until filing the
    counterclaims,‛ ‚IHC had no intention of collecting any shortfall
    amounts‛ because it would, of its own accord, change an
    otherwise unfulfilled charge to a balance of zero, and because
    IHC’s own witness admitted that he could not recall any time
    where ‚IHC *had+ ever attempted to collect [the unpaid
    amounts] from any patient whose insurer paid under the DRG
    reimbursement method.‛
    20140003-CA                    19                
    2016 UT App 73
    Maak v. IHC Health Services
    ¶42 Maak concludes, ‚*The undisputed facts+ demonstrate
    that IHC intentionally and unequivocally waived its purported
    counterclaims against any and all members of the Class by
    ‘accepting performance *that did+ not comport with contractual
    requirements [of its Patient Agreement].’‛ (Second and third
    alterations in original.) (Quoting Anderson, 
    756 P.2d at 98
    .)
    ¶43 IHC responds that its right to pursue the counterclaims
    did not exist until our prior decision in this matter. It insists that
    our 2007 ruling ‚changed the legal landscape and altered the
    understanding‛ of its contractual agreements and ‚*o+nly then
    did [it] know it had an independent right to collect shortfall[s]
    ‘pursuant to its contract with the patient.’‛ (Citation omitted.)
    IHC also disputes Maak’s characterization of its counterclaims.
    IHC argues, based on the many individual reimbursement
    agreements, that ‚individual adjudication is required for each
    class member to determine whether the waiver defense Maak
    raises applies.‛7 Finally, IHC contends that Maak incorrectly
    assumes that, in its reimbursement agreements with insurers
    other than Regence, IHC limited its ability to collect more than
    the patients’ deductible or coinsurance obligation determined by
    their benefit plan. IHC contends that because ‚Maak has no
    evidence‛ that all insurer agreements are similar to Regence’s,
    she cannot establish that IHC waived its right to collect the
    shortfall amounts against the class.
    ¶44 The district court appears not to have explicitly ruled on
    Maak’s motion for summary judgment on IHC’s counterclaims.
    Instead, the district court, in its final order granting
    decertification of the class, ruled that IHC’s counterclaims ‚are
    7. IHC does not elucidate its argument that a waiver
    determination would need to be made for each individual class
    member. Nor does the district court’s order analyze why waiver
    could not be adjudicated on a class-wide basis.
    20140003-CA                      20                
    2016 UT App 73
    Maak v. IHC Health Services
    no longer speculative, were not waived by IHC, and warrant
    decertification.‛ That sentence, together with a recognition that
    Maak’s interests might conflict with other class members due to
    the counterclaims, constitutes the district court’s entire factual
    and analytical discussion of whether IHC had waived its
    counterclaims and how the presence of those claims impacted
    the rule 23 factors.
    ¶45 The district court’s order does not provide us any insight
    into why it concluded the counterclaims had not been waived,
    nor does it indicate what record evidence supports its
    determination. ‚Failure of the [district] court to make findings
    on all material issues is reversible error.‛ Hill v. Estate of Allred,
    
    2009 UT 28
    , ¶ 59, 
    216 P.3d 929

    the basis of the [district] court’s decision‛ (citation and internal

    ¶46 Without insight into the district court’s reasoning, ‚we are

    II. The District Court’s Decertification of the Class
    A.     Rule 23’s Class Certification Requirements
    ¶47 Maak contends that the district court abused its discretion
    in decertifying the class because ‚this action presents a
    quintessential case for class-action adjudication‛—a resolved
    legal question imposing liability in a variety of similar factual
    scenarios.
    ¶48 Rule 23 of the Utah Rules of Civil Procedure sets forth the
    criteria for the certification of a class action suit. A class may be
    certified under rule 23 only if
    (1) the class is so numerous that joinder of all
    members is impracticable, (2) there are questions of
    law or fact common to the class, (3) the claims or
    defenses of the representative parties are typical of
    the claims or defenses of the class, and (4) the
    representative parties will fairly and adequately
    protect the interests of the class.
    Utah R. Civ. P. 23(a). ‚These four criteria are respectively
    referred to as (1) numerosity, (2) commonality, (3) typicality, and
    (4) adequacy of representation.‛ Jaques v. Midway Auto Plaza, Inc.,
    
    2010 UT 54
    , ¶ 23, 
    240 P.3d 769
    . Further, to maintain a class
    action, the case must ‚fall[] into one of the three categories found
    in rule 23(b).‛ 
    Id. ¶ 24
    . Applicable here, to maintain a class action
    the court must determine that ‚questions of law or fact common
    to the members of the class predominate over any questions
    affecting only individual members, and that a class action is
    superior to other available methods for the fair and efficient
    20140003-CA                     22                 
    2016 UT App 73
    Maak v. IHC Health Services
    adjudication of the controversy.‛ Utah R. Civ. P. 23(b)(3). These
    two concepts, enunciated in rule 23(b)(3), are referred to as
    predominance and superiority, respectively. See Jaques, 
    2010 UT 54
    , ¶ 24.
    B.     The District Court’s Order Granting IHC’s Motion to
    Decertify the Class
    ¶49 The district court concluded that, as a result of ‚the
    parties’ extensive discovery efforts,‛ the class no longer satisfied
    the requirements of commonality, typicality, predominance,
    adequacy of representation, and superiority under rule 23 of the
    Utah Rules of Civil Procedure. The court found that the
    contractual agreements governing many of the class members’
    claims were ‚materially different from *Maak’s+,‛ that ‚most
    overbillings *were+ not in a context similar to *Maak’s+,‛ and that
    identifying class members would require ‚individualized
    adjudications.‛ Thus the court concluded that the claims of the
    current class did not satisfy rule 23’s class certification
    requirements.
    ¶50 As part of its determination, the district court reasoned
    that IHC’s counterclaims weighed in favor of decertifying the
    class:
    [W]ith thousands of people identified in the Tier 2
    analysis subject to counterclaims that might
    involve widely varying degrees of damages, there
    can be no uniform alignment of interests, and no
    ability to generalize causation, injury, and liability.
    Additionally, given the pendency of what are now
    clearly significant counterclaims, the Court is
    concerned about the potential conflict of interest
    between [Maak] and class members who might be
    subject to those counterclaims. Those potential
    counterclaims . . . warrant decertification.

    Maak v. IHC Health Services
    ¶51 Because we have determined that the district court must
    revisit its holding with respect to IHC’s counterclaims, and
    because the district court relied upon the viability of IHC’s
    counterclaims in its decision to grant IHC’s motion to decertify
    the class, we vacate the district court’s grant of that motion. We
    decline to substantively review the district court’s decertification
    decision because it may be affected by the district court’s
    decision on remand. If the court determines on remand that
    IHC’s counterclaims are, in fact, waived, then it should conduct
    a new decertification analysis without regard to IHC’s
    counterclaims. If the court concludes that IHC has not waived its
    counterclaims, the district court should specifically address how
    the presence of those counterclaims affects the rule 23 analysis.8
    8. Maak challenges several other aspects of the district court’s
    decertification decision. For example, Maak also argues that the
    district court erred by allowing IHC to benefit from the missing
    EOBs. IHC argues that if EOBs were available, they would show
    that a number of class members do not qualify for class
    membership. IHC also argues that by asking that patients
    without EOBs be included in the class, Maak essentially asked
    the district court to adopt an inference adverse to IHC—an
    inference that IHC argues is unwarranted because IHC could not
    have known that it needed to preserve the EOBs. Maak contends
    that she did not ask the district court to sanction IHC based
    upon its alleged spoliation of evidence, only that IHC not be
    permitted to enjoy a positive inference from the missing
    evidence. See generally Ockey v. Club Jam, 
    2014 UT App 126

    328 P.3d 880
     (acknowledging that Utah Rule of Civil Procedure
    37 affords district courts broad discretion ‚to determine if a
    party’s *spoliation of evidence+ justifies the imposition of
    sanctions and, if so, which sanction is appropriate to the

    Maak v. IHC Health Services
    ¶52 Because the issue may arise on remand, we also address
    Maak’s argument that, even if IHC did not waive its
    counterclaims, the district court incorrectly determined that it
    had ‚no alternative‛ but to decertify in the face of IHC’s
    counterclaims. See Buford v. H & R Block, Inc., 
    168 F.R.D. 340
    , 363–
    64 (S.D. Ga. 1996) (recognizing that courts handle counterclaim
    issues ‚differently‛ in the class action context, such as by
    severing class members or by prosecuting claims separately, but
    recognizing that permissive counterclaims, ‚by themselves, will
    not defeat certification‛); Walczak v. Onyx Acceptance Corp., 
    850 N.E.2d 357
    , 371 (Ill. App. Ct. 2006) (concluding that ‚generally,
    individual counterclaims or defenses do not render a case
    unsuitable for class action‛ because counterclaims only reduce
    damages awards and do not affect the underlying finding of
    liability). Maak notes that courts around the country have
    adopted procedures to permit class actions to proceed despite
    the assertion of counterclaims against class members. See, e.g.,
    Roper v. Consurve, Inc., 
    578 F.2d 1106
    , 1116 (5th Cir. 1978)
    (directing that counterclaims against a class may be managed by
    ‚adopting standards and classifying the claims,‛ such as

    addressed the issue, other than to state in the decertification
    order that ‚the re-defined class essentially asks the Court to
    adopt an adverse [inference] against IHC, which is not
    appropriate.‛ Because of the factual issues to be resolved with
    respect to IHC’s destruction of the EOBs, and the district court’s
    broad discretion to craft appropriate remedies for spoliation,
    these arguments are best resolved by the district court in the first
    instance. Remand will permit Maak to renew her arguments
    with respect to spoliation and the other errors she argues on
    appeal and permit the district court to address them in the
    context of the other decisions before it on remand. Remand will
    also provide the district court an opportunity to fully explain the
    basis for its decisions.

    Maak v. IHC Health Services
    ‚excluding counter-claim defendants from the plaintiff class or
    separating and severing the class into two different classes, one
    with counter-claims and one without counter-claims‛); Partain v.
    First Nat. Bank of Montgomery, 
    59 F.R.D. 56
    , 59 (M.D. Ala. 1973)
    (concluding that it is appropriate for a district court to ‚exercise
    its discretion under Rule 23 [of the Federal Rules of Civil
    Procedure] to define the scope of the class by deleting from the
    proposed class all those persons‛ subject to counterclaim
    liability).
    ¶53 Utah law does not require a district court to sua sponte
    consider all options that it could employ to salvage a
    problematic class definition. We conclude, however, that when a
    party specifically proposes a mechanism to ameliorate concerns
    with class treatment, the district court must undertake a rigorous
    analysis and explain the basis for its decision to reject the
    proposed approach and to instead decertify the class.
    Accordingly, if the district court concludes that IHC has not
    waived its counterclaims and that such counterclaims cause the
    proposed class to fall short of rule 23’s strictures, the district
    court should specifically analyze any proposal Maak presents to
    address the proposed counterclaims. This is not to suggest that
    the district court must adopt any such proposal, only that it may
    not, without consideration and analysis, reject an attempt to
    salvage a class.
    ¶54 Accordingly, we vacate the district court’s order
    decertifying the class and remand the issue for reconsideration.
    III. Maak’s Motion to Amend the Class Definition
    ¶55 Maak also contends that the district court abused its
    discretion in denying her motion to amend the class definition.
    Maak argues that a proper class exists and that her amended
    class definition satisfies the elements of rule 23 of the Utah Rules
    of Civil Procedure. See Utah R. Civ. P. 23(a)–(b).

    2016 UT App 73
    Maak v. IHC Health Services
    ¶56    The district court determined,
    [A]lthough [Maak] has proposed a new class
    definition, the re-defined class essentially asks the
    Court to adopt an adverse [inference] against IHC,
    which is not appropriate, and in any event, the
    problem remains that establishing causation and
    damages would still require individualized
    adjudications to determine the facts of each specific
    case. The Court has no alternative but to decertify
    the conditionally certified class.
    Maak argues that this decision constitutes an abuse of discretion
    because ‚a proper class of some size exists.‛ Maak also argues
    that ‚*i+n a great number of cases‛ the relevant documents exist
    sufficient to establish ‚that the contractual adjustment at issue
    must have been made as a result of the billing policies
    [determined to be] in breach of Maak’s Patient Agreement.‛
    Thus, she argues, class action status is proper for some portion of
    the initial class, ‚even if it is smaller than the class as originally
    certified or the proposed amended Class that was the focus of
    Maak’s Motion to Amend.‛9
    9. It bears noting that on remand, Maak cannot simply argue that
    a proper class of some size must exist and ask the district court
    to establish the boundaries of that hypothetical class. See Utah R.
    Civ. P. 23(b) (setting out that an action may be maintained as a
    class if the plaintiff satisfies the prerequisites to a class action in
    rule 23(a) and (b)); Robidoux v. Celani, 
    987 F.2d 931
    , 935 (2d Cir.
    1993) (holding that rule 23 of the Federal Rules of Civil
    Procedure ‚requires a potential class representative‛ to establish
    that the class satisfies each of the rule’s elements); Nelson v. Wal-
    Mart Stores, Inc.,

    2016 UT App 73
    Maak v. IHC Health Services
    ¶57 The record before us does not permit us to evaluate the
    merits of Maak’s arguments. The district court’s order simply
    concludes that with Maak’s proposed amended class,
    ‚establishing causation and damages would still require
    individualized adjudications‛ and would require ‚the Court to
    adopt an adverse [inference] against IHC.‛ The district court’s
    order does not explain why the narrower class Maak proposed
    would require individualized determinations that would either
    prevent common issues from predominating or prevent class-
    action treatment from being a superior method of resolving this
    dispute. Without application of the rule 23 factors to the
    amended class Maak proposed, we cannot determine if the
    district court properly exercised its discretion. See Richardson v.
    Arizona Fuels Corp., 
    614 P.2d 636
    , 639 (Utah 1980) (holding that
    the district court erred by insufficiently analyzing the class
    action certification requirements in rule 23); cf. Pipefitters Local
    636 Ins. Fund v. Blue Cross Blue Shield of Mich., 
    654 F.3d 618
    , 630
    (6th Cir. 2011) (highlighting the need for ‚‘rigorous analysis’ by
    the district court as to all the requirements‛ of rule 23 of the
    Federal Rules of Civil Procedure due to the ‚huge amount of
    judicial resources expended by class actions‛ and concluding
    that the ‚absence of analysis‛ is reversible error); Ex parte Am.
    Bankers Life Assurance Co. of Fl., 
    715 So. 2d 186
    , 190–91 (Ala. 1997)

    elements‛ of Alabama’s class-certification rule and requiring that
    its analysis ‚not simply parrot the language of Rule 23(a) [of the

    2010) (‚The party seeking certification bears the burden of

    and one of the conditions in Rule 23(b) is met.‛). The district
    court is not required to play the role of Goldilocks and test the
    universe of potential classes until it finds one that is ‚just right.‛
    The party seeking an amendment of the class should propose a
    class definition for the court to analyze.

    Alabama Rules of Civil Procedure] but [instead] provide a
    written rigorous analysis of each element and explain how the

    proving these elements‛).
    ¶58 We therefore vacate the district court’s order denying
    Maak’s motion to amend the class definition and remand for
    further consideration. On remand, the court should review the
    dimensions of Maak’s amended class definition to determine
    specifically whether it satisfies the class certification
    requirements of rule 23 of the Utah Rules of Civil Procedure. The
    court should undertake the rigorous analysis rule 23 demands,
    and its written order should specifically analyze why Maak’s
    amended class definition either does or does not meet each
    element of rule 23. See Richardson, 614 P.2d at 639.10
    CONCLUSION
    ¶59 We vacate the district court’s order granting IHC’s motion
    to decertify the class and denying Maak’s motion to amend the
    class definition. We remand the case for (1) a redetermination of
    Maak’s argument that IHC has waived its counterclaims to allow
    the court to provide a developed explanation of its reasoning,
    (2) a new consideration of IHC’s motion to decertify the class to
    10. In vacating the district court’s order denying Maak’s motion
    to amend the class definition and remanding the case, we do not
    foreclose the district court’s ability, under the Utah Rules of Civil
    Procedure, to address any procedural, or other, issues that may
    arise or to set a course of proceedings for the case. See Utah R.
    Civ. P. 23(d) (providing that the district court may, among other
    things, ‚impos*e+ conditions on the representative parties‛ and
    ‚determin*e+ the course of proceedings or *prescribe+ measures
    to prevent undue repetition or complication in the presentation
    of evidence or argument‛).
