    _________________________________
    In these consolidated appeals, APP of New Mexico ED, PLLC (APP) and
    Lovelace Health System, LLC (Lovelace), appeal from the district court’s order
    remanding this putative class-action suit to New Mexico state court. Exercising
    jurisdiction under 
    28 U.S.C. § 1453
    (c)(1), we affirm.
    I.
    Plaintiffs in this suit are former patients who sought treatment at Lovelace
    facilities located in the state of New Mexico. They allege that APP, a company that
    provides emergency room physician and nurse practitioner staffing for Lovelace
    facilities, overbilled them at out-of-network rates even though plaintiffs were
    in-network with Lovelace. Plaintiffs filed this class action against APP and Lovelace
    in New Mexico state court in February 2020. Their complaint included claims for
    violations of the New Mexico Unfair Practices Act, conversion, willful breach of
    *
    After examining the briefs and appellate record, this panel has determined
    unanimously that oral argument would not materially assist in the determination of
    this appeal. See Fed. R. App. P. 34(a)(2); 10th Cir. R. 34.1(G). The case is therefore
    ordered submitted without oral argument. This order and judgment is not binding
    precedent, except under the doctrines of law of the case, res judicata, and collateral
    estoppel. It may be cited, however, for its persuasive value consistent with
    Fed. R. App. P. 32.1 and 10th Cir. R. 32.1.
    2
    Appellate Case: 22-2057     Document: 010110710056        Date Filed: 07/13/2022     Page: 3
    contract, unjust enrichment, and civil conspiracy. They sought certification of a
    proposed class including “all New Mexico residents who, beginning four years prior
    to the filing date of this lawsuit, were billed by APP for amounts greater than the
    in-network amount permitted by their insurance provider for medical services
    provided at Lovelace facilities.” J.A., Vol. I at 40.
    APP, which is a limited liability company with its principal place of business
    in Tennessee, removed the action to federal court based on the Class Action Fairness
    Act (CAFA). CAFA grants district courts jurisdiction over class actions involving at
    least 100 proposed class members, more than $5,000,000 in controversy, and the
    presence of a plaintiff class member who is a citizen of a state different from any
    defendant. See 
    28 U.S.C. § 1332
    (d)(2)(A), (d)(5)(B). Lovelace consented to the
    removal.
    Plaintiffs later filed a motion to remand the case to state court. They asserted
    the case should be remanded because defendants had failed to establish that more
    than $5,000,000 was in controversy. They further argued that even assuming the
    amount-in-controversy requirements were met, CAFA’s “local controversy
    exception” mandated that the action remain in state court. The local controversy
    exception requires a district court to decline jurisdiction if (1) “greater than two-
    thirds of the members of all proposed plaintiff classes in the aggregate are citizens of
    the State in which the action was originally filed”; (2) the action seeks “significant
    relief” from at least one defendant “whose alleged conduct forms a significant basis
    for the claims asserted by the proposed plaintiff class,” and “who is a citizen of the
    3
    Appellate Case: 22-2057     Document: 010110710056        Date Filed: 07/13/2022     Page: 4
    State in which the action was originally filed”; (3) the plaintiffs’ principal injuries
    “were incurred in the State in which the action was originally filed”; and (4) “during
    the 3-year period preceding the filing of that class action, no other class action has
    been filed asserting the same or similar factual allegations against any of the
    defendants on behalf of the same or other persons.” 
    Id.
     § 1332(d)(4)(A).
    The district court found that the $5,000,000 jurisdictional threshold was met.
    That determination is not challenged in this appeal. It also initially found that the
    plaintiffs had failed to show that the local controversy exception applied because they
    failed to establish that more than two-thirds of the proposed class members, whom
    the complaint defined as New Mexico residents, were also New Mexico citizens. The
    district court then took plaintiffs’ motion to remand under advisement and provided
    them with the opportunity to conduct limited discovery on the question of class
    citizenship.
    Plaintiffs filed an amended motion to remand. In connection with the amended
    motion, they produced an expert report from Professor James H. Degnan, an
    Associate Professor in the Department of Mathematics and Statistics at the University
    of New Mexico. Based on a statistical sampling Dr. Degnan conducted, plaintiffs
    argued they had proved that more than two-thirds of the class members were citizens
    of New Mexico.
    In his expert report, Dr. Degnan explained that APP had provided plaintiffs
    with information concerning all people who received services from APP during the
    four-year period covered by the lawsuit who were in-network with Lovelace and
    4
    Appellate Case: 22-2057    Document: 010110710056        Date Filed: 07/13/2022     Page: 5
    out-of-network with APP. From that list, plaintiffs’ counsel removed transactions in
    which a customer did not have a New Mexico address, was not billed by APP, or
    received the first bill from APP after APP had already received payment. They also
    removed duplicate entries. This left 29,351 class member records. Professor Degnan
    then created a random sample of 100 class members from the revised list and
    provided the sample to plaintiffs’ counsel.
    Law firm employees contacted the class members on the list by telephone and
    surveyed them using a script format agreed upon by the parties. The telephone
    survey showed that, of the 100 sample class members, 52 affirmed their New Mexico
    citizenship, one stated he was not a citizen, and 47 either would not respond or could
    not be reached. Plaintiffs then retained a service that performed a “skip trace” to
    determine if additional information could be obtained about the 47 non-respondents.
    This skip tracing uncovered information concerning 83 of the 100 class members:1
    their current residential address, property ownership on February 11, 2020 (the date
    the complaint was filed), and vehicle registration on February 11, 2020.2
    1
    It is unclear what proportion of these 83 class members were respondents vs.
    non-respondents to the telephone survey. The Director of Operations at the skip
    tracing company filed a declaration stating that 20 of the non-respondents yielded
    New Mexico “data in 0 or 1 of the 3 categories.” See J.A., Vol. I at 231. Id. Data in
    “zero” categories appears to mean no data was found for a particular non-respondent,
    either in New Mexico or elsewhere. This would indicate that a particular non-
    respondent was one of the 17 out of 100 class members for whom skip tracing
    yielded no data.
    2
    Plaintiffs initially sought vehicle registration and driver’s license information
    from the New Mexico Taxation and Revenue Department (NMTRD), but the
    response they received from NMTRD was redacted, making it impossible to match
    5
    Appellate Case: 22-2057    Document: 010110710056        Date Filed: 07/13/2022    Page: 6
    The skip tracing confirmed the data from the survey respondents. None of the
    class members who had affirmed their New Mexico citizenship were shown to be
    identified with non-New Mexico data in any of the three categories.
    The skip tracing also yielded data concerning the 47 non-respondents. Of
    those non-respondents, 27 were identified with New Mexico data in at least two of
    the three categories and had no non-New Mexico data in any category. The other 20
    non-respondents either were identified with New Mexico data in only zero or one of
    the three categories or were identified with non-New Mexico data in one or more of
    the categories. Dr. Degnan then added the 52 class members who had affirmed their
    New Mexico citizenship to the 27 non-respondents who met at least two of the three
    categories to conclude that “79 of the 100 class members in the random sample were
    identified as citizens of New Mexico as of the date of filing the complaint.” J.A.,
    Vol. I at 210.3 He concluded with “[a] 95% confidence interval for this data . . . that
    the true proportion of New Mexico citizens from the population of 29,351 individuals
    sampled is larger than 2/3.” Id. In other words, the survey results combined with the
    the documents to the class members. See J.A., Vol. II at 436. Plaintiffs also sought
    voter registration information from the New Mexico Secretary of State but received
    no response. See id.
    3
    Although Dr. Degnan’s report merely states that the skip trace revealed data
    in two of the three categories—which could be understood to mean any two of
    plaintiffs’ three criteria—the parties later clarified that “the 2 of 3 test [for
    citizenship] meant a finding of continuous residence plus at least one of the two other
    categories (vehicle registration or property ownership).” J.A., Vol. II at 450 n.6
    (internal quotation marks omitted).
    6
    Appellate Case: 22-2057     Document: 010110710056         Date Filed: 07/13/2022    Page: 7
    skip-tracing results showed that the class met the two-thirds requirement for the local
    controversy exception.4
    Defendants produced their own expert report that criticized the scientific
    reliability of Dr. Degnan’s report. They again opposed plaintiffs’ motion to remand,
    arguing plaintiffs had failed to meet the local controversy requirement because they
    had failed to show that (1) two-thirds of the proposed class were citizens of New
    Mexico, and (2) the New Mexico defendant named in the complaint, Lovelace, was a
    “significant defendant” whose conduct formed a significant basis for plaintiffs’
    claims and from whom plaintiffs sought significant relief. The district court
    determined that plaintiffs met their burden to show that the local controversy
    requirements were met. It therefore granted their motion to remand.
    APP and Lovelace filed petitions for permission to appeal, see 
    28 U.S.C. § 1453
    (c)(1), which we granted.
    II.
    A.
    “CAFA was enacted to respond to perceived abusive practices by plaintiffs
    and their attorneys in litigating major class actions with interstate features in state
    courts.” Woods v. Standard Ins. Co., 
    771 F.3d 1257
    , 1262 (10th Cir. 2014) (internal
    quotation marks omitted). CAFA permits a federal court to assume original
    4
    Dr. Degnan also produced a supplemental report, see J.A., Vol. I at 232-34,
    but the district court struck it and did not consider it in connection with its decision,
    see 
    id.,
     Vol. II at 443 n.3.
    7
    Appellate Case: 22-2057     Document: 010110710056       Date Filed: 07/13/2022       Page: 8
    jurisdiction if certain requirements are met. See 
    id.
     Congress included several
    exceptions to CAFA’s removal procedure. The party seeking a remand to the state
    court under one of these exceptions bears the burden of showing by a preponderance
    of the evidence that the exercise of federal court jurisdiction is improper. See id.;
    Mondragon v. Cap. One Auto Fin., 
    736 F.3d 880
    , 884 (9th Cir. 2013) (stating
    preponderance standard).
    The local controversy exception “is intended to respond to concerns that class
    actions with a truly local focus should not be moved to federal court under this
    legislation because state courts have a strong interest in adjudicating such disputes.”
    Woods, 771 F.3d at 1262 (internal quotation marks omitted). “Rather than divesting
    a court of jurisdiction, the local controversy exception operates as an abstention
    doctrine” under which the federal court abstains from hearing the case in favor of the
    state’s demonstrated interest in the dispute. Dutcher v. Matheson, 
    840 F.3d 1183
    ,
    1190 (10th Cir. 2016) (internal quotation marks omitted). It “is a narrow exception
    that was carefully drafted to ensure that it does not become a jurisdictional loophole
    and all doubts are resolved in favor of exercising jurisdiction over the case.” 
    Id.
    (brackets and internal quotation marks omitted). “[R]emand is mandatory if the
    plaintiffs can show that they meet the requirements of the local controversy
    exception.” 
    Id.
    B.
    We review de novo the district court’s interpretation of CAFA. See Woods,
    771 F.3d at 1262. We review the district court’s factual findings for clear error.
    8
    Appellate Case: 22-2057     Document: 010110710056          Date Filed: 07/13/2022      Page: 9
    Mondragon, 736 F.3d at 886. “Under that standard, we may reverse only if the
    district court’s finding lacks factual support in the record or if, after reviewing all the
    evidence, we have a definite and firm conviction that the district court erred.”
    Middleton v. Stephenson, 
    749 F.3d 1197
    , 1201 (10th Cir. 2014). The district court’s
    findings concerning citizenship are factual findings subject to our clearly erroneous
    review. See 
    id.
     (diversity jurisdiction case).
    III.
    Defendants challenge the district court’s finding that plaintiffs showed more
    than two-thirds of class members are New Mexico citizens. See 
    28 U.S.C. § 1332
    (d)(4)(A)(i)(I). “[A] person is a citizen of a state if the person is domiciled in
    that state.” Middleton, 749 F.3d at 1200. “[A] person acquires domicile in a state
    when the person resides there and intends to remain there indefinitely,” a status that
    courts typically discern from the “totality of the circumstances.” Id. at 1200-01.
    We have described the citizenship inquiry as “an all-things-considered
    approach” in which “any number of factors might shed light on the subject in any
    given case.” Id. at 1201. Relevant factors include
    the party’s current residence; voter registration and voting practices; situs
    of personal and real property; location of brokerage and bank accounts;
    membership in unions, fraternal organizations, churches, clubs, and other
    associations; place of employment or business; driver’s license and
    automobile registration; payment of taxes; as well as several other aspects
    of human life and activity.
    Id. (internal quotation marks omitted). Although a person’s “place of residence is
    prima facie the domicile,” State Farm Mut. Auto. Ins. Co. v. Dyer, 
    19 F.3d 514
    , 520
    9
    Appellate Case: 22-2057    Document: 010110710056        Date Filed: 07/13/2022       Page: 10
    (10th Cir. 1994), something more than residence in a state is required to show the
    intent to remain in the state, see Whitelock v. Leatherman, 
    460 F.2d 507
    , 514
    (10th Cir. 1972) (“[A]llegations of mere ‘residence’ may not be equated with
    ‘citizenship.’”).
    Defendants contend the district court’s citizenship finding was clearly
    erroneous because plaintiffs’ method of proof, which the district court accepted, was
    unreliable or inadequate. Because it is impracticable to obtain information
    concerning citizenship of all the members of a large class, affidavits or survey
    responses targeting a representative sample of class members is a legitimate means of
    satisfying a plaintiff’s burden under a CAFA exception. See, e.g., In re Sprint Nextel
    Corp., 
    593 F.3d 669
    , 675-76 (7th Cir. 2010) (stating that “affidavits or survey
    responses in which putative class members reveal whether they intend to remain in
    Kansas indefinitely” might be sufficient to establish citizenship of those survey
    respondents under CAFA’s home-state exception). Defendants argue, however, that
    plaintiffs’ approach in this case, which involved a survey to which nearly half those
    surveyed failed to respond, coupled with skip tracing that obtained information on
    only a few citizenship-related factors concerning the non-respondents, did not
    produce reliable indicia of citizenship. They claim plaintiffs’ method was flawed
    because it allowed them to count a significant number of non-responding class
    members—for whom there was only skip-trace evidence of current New Mexico
    residency plus either evidence of New Mexico property ownership or vehicle
    registration—as New Mexico citizens. They argue that the district court’s reliance
    10
    Appellate Case: 22-2057     Document: 010110710056        Date Filed: 07/13/2022       Page: 11
    on only these few factors rather than the totality of potentially relevant
    considerations, as discussed in Middleton, was erroneous.5
    Middleton was a non-class-action case where we were concerned with the
    citizenship of a single defendant who had raised counterclaims and third-party claims
    in reliance on diversity jurisdiction. 749 F.3d at 1198-1200. The determination of
    domicile used in non-class-action cases risks becoming unnecessarily arduous when
    transported to the context of CAFA exceptions. See Preston v. Tenet Healthsystem
    Mem’l Med. Ctr., Inc., 
    485 F.3d 804
    , 816 (5th Cir. 2007). A better approach when
    determining CAFA exceptions is to use an evidentiary standard “based on practicality
    and reasonableness.” 
    Id.
     Under this approach, defendants fail to show that the
    plaintiffs’ method was unreasonable.
    5
    Defendants suggest that plaintiffs cherry-picked the available data. They
    complain, for example, that plaintiffs gathered employment data but chose not to use
    it in the citizenship inquiry. But the district court explained the plaintiffs’ reasons
    for not relying on the employment data:
    Plaintiffs chose not to use this data because they could not draw inferences
    from it, one way or another, due to various problems such as old
    information and that some data lacked corresponding addresses or provided
    an address of a corporate office instead of a local office. In other words,
    the data could not be used to reliably determine whether a person was
    employed in New Mexico.
    J.A., Vol. II at 460. We discern no error in this determination. Also, as we have
    noted, see supra n.2, plaintiffs sought data for the sample on vehicle registration and
    driver’s licenses but were unable to obtain usable information concerning these
    factors. These facts do not suggest that plaintiffs relied on only the available data
    that favored their position.
    11
    Appellate Case: 22-2057     Document: 010110710056         Date Filed: 07/13/2022     Page: 12
    Defendants contend that residency plus property ownership in a state does not
    necessarily equal citizenship. They cite the examples of military members, students,
    or green card holders, who may reside in New Mexico and own property there
    without being New Mexico citizens. It is true that residency in a state does not
    equate to citizenship, see Whitelock, 
    460 F.2d at 514
    , and that property ownership in
    a state, without more, does not establish citizenship in that state, see, e.g., Evans v.
    Walter Indus., Inc., 
    449 F.3d 1159
    , 1165-66 (11th Cir. 2006). Here, however, two
    additional factors enhanced the reliability of the finding that those non-respondents
    were in fact New Mexico citizens. First, the skip-tracing uncovered no data that they
    resided, owned property, or had registered vehicles in any other state. Second, they
    were residents of New Mexico both when they received the medical service and years
    later, when the skip tracing was performed. Both these factors support the district
    court’s conclusion that these class members were not only residents of New Mexico
    but also were citizens who intended to remain within that state.
    These additional facts also rebut two other arguments the defendants make,
    that (1) even if plaintiffs established New Mexico citizenship by a preponderance of
    the evidence for each of the 27 non-responding class members who met the
    “residency plus one” test, and assuming that each of these class members therefore
    has “a 51% likelihood of citizenship, then it is highly unlikely that every single one
    of these 27 class members would be a citizen”; and that (2) random sampling of a
    class should only be used to determine citizenship when “the surveyed members of
    the sample confirm their citizenship.” Aplt. Opening Br. at 38 (emphasis omitted).
    12
    Appellate Case: 22-2057    Document: 010110710056        Date Filed: 07/13/2022    Page: 13
    First, we see no reason to conclude that the “residency plus one” method, when
    combined with other reasonable inferences to be drawn from the skip-tracing data,
    yielded only a 51 percent likelihood that each non-responding class member was a
    citizen. Second, skip tracing, when properly conducted, is a legitimate means of
    determining citizenship, particularly when a telephone survey yields too few results
    to provide an adequate analysis of the proposed class. “What is in another man’s
    mind must be determined by what he does as well as by what he says.” Smith v.
    Marcus & Millichap, Inc., 
    991 F.3d 1145
    , 1157 (11th Cir. 2021) (internal quotation
    marks omitted). Skip tracing provides objective evidence of a party’s intent to be
    domiciled in a particular state, and in the citizenship context. See Preston, 
    485 F.3d at 817
     (stating the district court has broad discretion to determine what evidence to
    use in making a jurisdictional determination).
    It is true that in determining citizenship, a court may not rely on guesswork,
    even “[s]ensible guesswork.” Sprint Nextel, 
    593 F.3d at 674
     (stating that although
    the court was “inclined to think that at least two-thirds of those who have Kansas cell
    phone numbers and use Kansas mailing addresses for their cell phone bills are
    probably Kansas citizens,” such a common-sense conclusion based on “[s]ensible
    guesswork” was insufficient to determine citizenship because “a court may not draw
    conclusions about the citizenship of class members based on things like their phone
    numbers and mailing addresses”). But the district court’s determination here was
    based on reasonable inferences drawn from the available data and did not represent
    13
    Appellate Case: 22-2057     Document: 010110710056        Date Filed: 07/13/2022    Page: 14
    mere guesswork. We cannot conclude that its citizenship determination was clearly
    erroneous.6
    Finally, we note that defendants cite two unpublished cases from this court that
    discuss citizenship in the CAFA context. Each is distinguished on its facts and is not
    inconsistent with our result.
    In Nichols v. Chesapeake Operating, LLC, 718 F. App’x 736 (10th Cir. 2018),
    the district court denied the plaintiff’s motion to remand his putative class-action
    case to state court under the “home state” exception, which requires that two-thirds or
    more of the class members must be citizens of the state where the action was filed.
    See 
    id. at 738
    . His complaint described a class of “Oklahoma Residents” who had
    received royalty checks from the defendant. 
    Id.
     (internal quotation marks omitted).
    To establish citizenship of class members for CAFA exception purposes, the plaintiff
    used a statistician, who (as in this case) randomly selected 100 royalty owners out of
    the thousands of potential class members. See 
    id.
     After successfully surveying 54 of
    those 100 sample members, by asking them “whether they considered themselves to
    be Oklahoma citizens and whether they planned to move from Oklahoma in the near
    future,” and, in the case of businesses, “whether they were organized or
    6
    Defendants suggest that plaintiffs were required not only to prove that two-
    thirds of the members of the representative sample were New Mexico citizens, but
    also to provide prove that they were United States citizens. See Aplt. Opening Br.
    at 33 n.5. Defendants fail to show they made this argument in district court; we
    therefore decline to consider it. See Richison v. Ernest Grp., Inc., 
    634 F.3d 1123
    ,
    1127-28 (10th Cir. 2011).

    headquartered in Oklahoma,” plaintiff’s counsel “determined that 95% of the
    sample’s royalty owners were Oklahoma citizens because the data shows indicia of
    Oklahoma citizenship with no conflicting data of citizenship elsewhere.” Id. at 739
    (internal quotation marks omitted).7
    The district court rejected counsel’s approach, finding significant flaws in the
    evidence and concluding, among other things, that “counsel had an insufficient basis
    for determining that some members of the random sample were Oklahoma citizens.”
    Id. (internal quotation marks omitted). “For instance, the skip-trace reports indicated
    that only 35 of the sample’s class members had Oklahoma driver’s licenses and that
    37 members had non-Oklahoma addresses.” Id. n.2.
    In upholding the district court’s result, we emphasized the “flawed” nature of the
    sample and counsel’s failure to “dispute these problems or otherwise explain how [the
    expert’s] evidentiary extrapolation remains statistically viable.” Id. at 742. The result in
    Nichols is consistent with this case, given that the survey/skip-trace in Nichols was
    significantly less reliable than those here.
    In Reece v. AES Corp., 638 F. App’x 755 (10th Cir. 2016), the district court
    denied the plaintiffs’ motions to remand their putative class action to state court under
    CAFA’s “local controversy,” “home state,” and “interests of justice” exceptions, and
    ultimately dismissed their complaint. See id. at 756, 759. The class was defined as “all
    7
    Although Nichols mentions a “skip-trace investigation,” see 718 F. App’x at
    739, it is unclear from the decision to what extent the survey results were
    supplemented by skip tracing, or for how many of the 46 unsuccessfully surveyed
    sample class members skip trace data was obtained.
    15
    Appellate Case: 22-2057      Document: 010110710056          Date Filed: 07/13/2022     Page: 16
    citizens and/or residents and/or property owners of the State of Oklahoma” who were in
    defined proximity to certain pollution-creating operations maintained by the defendants.
    Id. at 759.
    In their renewed motion for remand, plaintiffs relied solely on the “local
    controversy” exception. See id. at 760 & n.8. They provided an affidavit from an expert
    who had analyzed property records within the class area and had concluded that at least
    two-thirds of the proposed class members were Oklahoma residents. See id. at 760-61.
    Plaintiffs did not include the records that underlay the expert’s analysis. See id. at 761.
    The district court denied the renewed motion.
    On appeal, the Reece court addressed the legal difference between residence and
    citizenship. See id. at 769. It concluded that where a class is defined as “residents”
    rather than “citizens” (as in our case), the plaintiffs seeking remand must “marshal and
    present some persuasive substantive evidence (extrinsic to the amended petition) to
    establish the [state] citizenship of the class members.” Id. The Reece plaintiffs had
    failed to meet this standard because they had failed to “validate the conclusions contained
    in the summary exhibits by, for example, presenting to the court the records upon which
    the exhibits were ostensibly based or offering sworn testimony regarding the analysis
    underlying the conclusions.” Id. at 770. Given that the complaint included plaintiffs
    from a twenty-year period that might not have currently been residents or citizens of
    Oklahoma, and that the plaintiffs’ evidence dealt with residence rather than citizenship,
    the materials submitted with the first motion for remand were insufficient. Id. at 771.
    16
    Appellate Case: 22-2057     Document: 010110710056         Date Filed: 07/13/2022       Page: 17
    The expert’s affidavit submitted with the renewed motion failed to cure the
    fundamental defects of the first motion, because it was “framed in terms of residency,
    not citizenship.” Id. at 774. In this case, by contrast, the extrinsic proof offered by
    the plaintiffs is framed in terms of citizenship, not mere residency. There is
    sufficient additional evidence on which the district court could rely in determining
    citizenship.
    IV.
    Defendants also challenge the district court’s determination that Lovelace is a
    “significant” local defendant—that is, one “whose alleged conduct forms a
    significant basis for the claims asserted by the proposed plaintiff class” and from
    whom plaintiffs seek “significant relief.” 
    28 U.S.C. § 1332
    (d)(4)(A)(i)(II).8 “CAFA
    itself does not describe the type or character of conduct that would form a
    ‘significant basis’ of plaintiffs’ claims or define the term ‘significant relief.’”
    Woods, 771 F.3d at 1265. But to further CAFA’s statutory purposes, “we interpret
    the significant local defendant requirement strictly so that plaintiffs and their
    attorneys may not defeat CAFA jurisdiction by routinely naming at least one state
    citizen as a defendant, irrespective of whether that defendant is actually a primary
    focus of the litigation.” Id.
    8
    Defendants do not challenge Lovelace’s New Mexico citizenship, so no issue
    concerning that factor is before us.
    17
    Appellate Case: 22-2057     Document: 010110710056         Date Filed: 07/13/2022         Page: 18
    In Woods, we distilled the following guidelines from CAFA’s legislative
    history for determining whether a defendant named in the complaint meets the
    statute’s significant-local-defendant requirements:
    [F]or the local controversy exception to apply there must be at least one real
    defendant . . . whose alleged conduct is central to the class’s claims and
    from whom the class seeks significant relief. . . . [T]he local defendant must
    be a primary focus of the plaintiffs’ claims—not just a peripheral
    defendant. The defendant must be a target from whom significant relief is
    sought by the class (as opposed to just a subset of the class membership), as
    well as being a defendant whose alleged conduct forms a significant basis
    for the claims asserted by the class.
    Id. at 1266 (citation and internal quotation marks omitted).
    The district court determined that plaintiffs’ complaint adequately alleged that
    Lovelace’s conduct formed a significant basis for the claims the class asserted. In
    addition to reviewing the complaint, it accepted extrinsic evidence from the
    defendants but found this evidence unconvincing. The district court noted:
    [A]lthough Plaintiffs allege that APP was the party responsible for the
    actual overbilling, they also allege Lovelace was a significant player in an
    alleged overbilling scheme. They allege that Lovelace interacted with all of
    the proposed class members by advertising itself as in-network, failing to
    disclose its relationship with APP and APP’s billing practices, treating the
    Plaintiffs, and then benefitting from APP’s overbilling. Indeed, they allege
    that both Lovelace and APP are agents for the other and ratified each
    other’s misconduct.
    J.A., Vol. II at 464.
    The district court further determined that plaintiffs sought significant relief
    from Lovelace. It found that “Plaintiffs’ complaint makes clear that Lovelace is a
    primary target of litigation and a defendant from whom the entire class of plaintiffs
    seeks relief”; that the plaintiffs alleged that defendants were “jointly and severally
    18
    Appellate Case: 22-2057     Document: 010110710056         Date Filed: 07/13/2022     Page: 19
    liable for all damages and that each are directly liable; are liable for aiding, abetting,
    participating in, and ratifying the other parties’ conduct; are vicariously liable for
    each other’s misconduct; and are liable as members of a joint enterprise”; and that
    plaintiffs’ five claims for relief were each asserted against both Lovelace and APP
    for their joint overbilling scheme. Id. at 467-68 (internal quotation marks omitted).
    A.
    To determine whether the “significant basis” element is met, we examine
    whether the local defendant’s conduct “forms a significant basis for the claims
    asserted by the class.” Woods, 771 F.3d at 1266. Defendants argue that “[o]nly
    APP’s alleged conduct,” not Lovelace’s, “forms a significant basis of Plaintiffs’
    claims.” Aplt. Opening Br. at 17. But we agree with the district court’s conclusion
    that “Lovelace is a real target of the litigation,” based on Lovelace’s conduct
    identified in the complaint. J.A., Vol. II at 465. Although APP allegedly committed
    the overbilling, APP could not have done so “had Lovelace not advertised itself as in-
    network, treated the patients, contracted with APP, and failed to disclose to patients
    its relationship with APP.” Id. at 466.
    The complaint thoroughly describes Lovelace’s role in the alleged scheme,
    which includes alleged misrepresentations and material omissions made by Lovelace.
    It alleges that “Lovelace holds out to the public that it is an in-network provider for
    numerous insurance plans” but that Lovelace does not disclose numerous features of
    its relationship with APP to patients, including the fact that “they may end up paying
    more than the in-network rate for services provided by APP employees.” J.A., Vol. I
    19
    Appellate Case: 22-2057     Document: 010110710056          Date Filed: 07/13/2022       Page: 20
    at 33-34. The complaint further alleges that although “ostensibly, Lovelace takes the
    position that such overbilling should not be taking place,” in reality, “Lovelace
    benefits from APP’s overbilling” and “Lovelace and APP are part of a joint
    enterprise” and “acted as one another’s agents in the conduct described.” Id. at 34.
    In addition, each of the claims for relief asserts that the potential plaintiffs are
    entitled to recover from Lovelace, and that the defendants are liable for each other’s
    alleged misconduct, and the prayer for relief asks that defendants be found jointly
    and severally liable for all damages. We agree with the district court that the
    language in the complaint satisfies the significant basis element.
    Defendants cite extrinsic evidence that they claim contradicts the complaint
    and undermines plaintiffs’ claims. Assuming this evidence may be considered in
    determining whether Lovelace is a significant local defendant, the extrinsic evidence
    fails to defeat plaintiffs’ showing concerning that element.
    First, defendants point to the “Consent to Treatment” forms that Lovelace
    provides to patients. See Aplt. Opening Br. at 25-26. These forms require patients to
    acknowledge (1) that Lovelace has not represented or taken actions to induce the
    patient to believe that the physicians, residents, medical students, and nurses
    providing treatment are Lovelace employees, and (2) that the patient will receive a
    separate bill from the provider. But this language does not notify patients of an
    important fact that forms the gist of plaintiffs’ claims: that patients may end up
    paying more than the in-network rate for services provided by APP employees.
    20
    Appellate Case: 22-2057     Document: 010110710056         Date Filed: 07/13/2022     Page: 21
    Second, defendants cite testimony from APP’s Rule 30(b)(6) representative
    which indicates that Lovelace did not participate in APP’s billing procedures. But
    the mere fact that APP sent the bills does not show that Lovelace’s conduct,
    including alleged omissions and misrepresentations, fails to form a significant basis
    for plaintiffs’ claims. We therefore conclude that neither item of extrinsic evidence
    undermines the district court’s conclusion that Lovelace is a significant local
    defendant.
    B.
    Defendants argued in district court that plaintiffs did not seek significant relief
    from Lovelace because their complaint did not plausibly state a claim for relief
    against Lovelace. In evaluating this assertion, the district court stated it was not
    considering the merits of the claims, only whether they sought significant relief. The
    district court then rejected defendants’ argument in part because the claims “d[id] not
    appear frivolous on their face.” J.A., Vol. II at 468. Defendants argue the district
    court should have analyzed the claims under the plausibility standard described in
    Ashcroft v. Iqbal, 
    556 U.S. 662
    , 678 (2009) and Bell Atlantic Corp. v. Twombly,
    
    550 U.S. 554
    , 555 (2007), not a frivolousness standard. Defendants then supply an
    analysis of each of plaintiffs’ claims, asserting that each fails to state a claim against
    Lovelace under the Iqbal/Twombly analysis.
    21
    Appellate Case: 22-2057     Document: 010110710056        Date Filed: 07/13/2022     Page: 22
    Assuming the Iqbal/Twombly standard plays a role in assessing whether
    plaintiffs’ claims seek significant relief from Lovelace,9 we discern no reversible
    error here. Under that standard, plaintiffs’ allegations need only be sufficient to raise
    their “right to relief above the speculative level.” Twombly, 550 U.S. at 555. “A
    claim has facial plausibility when the plaintiff pleads factual content that allows the
    court to draw the reasonable inference that the defendant is liable for the misconduct
    alleged.” Iqbal, 
    556 U.S. at 678
    . Defendants have not shown that plaintiffs’
    complaint fails the plausibility standard for purposes of our threshold jurisdictional
    analysis.
    Defendants assert that plaintiffs’ first claim, under the New Mexico Unfair
    Practices Act, 
    N.M. Stat. Ann. §§ 57-12-1
     to 26, fails because it “does not allege that
    Lovelace was aware of APP’s alleged misconduct, and therefore could not have
    intentionally misled patients”; because it does not allege that Lovelace made some
    other representation that would become misleading in the absence of a disclosure;
    9
    Whether and how the standard applies to this inquiry seems less than clear.
    See Allen v. Boeing Co., 
    821 F.3d 1111
    , 1119 n.8 (9th Cir. 2016) (stating that “for
    purposes of assessing the applicability of [CAFA’s] local controversy exception, we
    can ignore a claim against [the local defendant] only if that claim is immaterial,
    insubstantial, or frivolous on its face,” but alternatively applying the Iqbal/Twombly
    standard to the relevant claim (internal quotation marks omitted)). It has also been
    suggested that rather than applying the federally based Iqbal/Twombly standard to
    such inquiries, a federal court should view the pleadings as a state court (in this case,
    New Mexico) would view them. See Arbuckle Mtn. Ranch of Tex., Inc. v.
    Chesapeake Energy Corp., 
    810 F.3d 335
    , 343-44 (5th Cir. 2016) (Elrod, J.,
    dissenting). We need not definitively resolve this issue, however, because New
    Mexico’s “notice pleading” rules appear to be at least as liberal to a plaintiff’s
    pleadings as the Iqbal/Twombly standard. See Madrid v. Vill. of Chama, 
    283 P.3d 871
    , 875-76 (N.M. Ct. App. 2012).
    22
    Appellate Case: 22-2057     Document: 010110710056        Date Filed: 07/13/2022    Page: 23
    and because it fails to show that any alleged omission was material. Aplt. Opening
    Br. at 19-20. But the complaint alleges that Lovelace “holds out to the public that it
    is an in-network provider for numerous insurance plans” but “does not state to its
    patients that they may end up paying more than the in-network rate for services
    provided by APP employees.” J.A., Vol. I at 33-34. The complaint states that
    “Lovelace takes the position that such overbilling should not be taking place,” 
    id. at 34
    , which could lead a court to reasonably infer that Lovelace is aware that “such
    overbilling” is taking place. The complaint also alleges sufficient facts to show
    materiality, given that plaintiffs chose to obtain care at Lovelace facilities because
    they were informed that Lovelace was an in-network provider under their insurance
    coverage, and their damages flowed from overbilling that exceeded the in-network
    rate. These factual allegations are sufficient to show that plaintiffs’ Unfair Practices
    Act claim seeks significant relief from Lovelace.
    Defendants assert that plaintiffs’ conversion claim fails against Lovelace
    because any alleged overpayments were made to APP, not Lovelace. The complaint
    alleges, however, that Lovelace and APP operated as a “joint enterprise,” “agreed to
    share their money, property, employees, and time in pursuit of their emergency room
    business,” and “share the profits and losses of the business and they are subject to
    mutual control over the business.” 
    Id.
     Although a threadbare assertion of “joint and
    several liability” cannot make an otherwise insignificant defendant significant, see
    Woods, 771 F.3d at 1269, where the plaintiffs’ damage claim rests on a claim of joint
    and several liability implicating the local defendant’s own conduct, the significant
    23
    Appellate Case: 22-2057     Document: 010110710056        Date Filed: 07/13/2022       Page: 24
    relief requirement may be satisfied, see Coffey v. Freeport McMoran Copper & Gold,
    
    581 F.3d 1240
    , 1244 (10th Cir. 2009). That standard is met here.
    Defendants assert that plaintiffs’ claim for breach of contract fails against
    Lovelace because their complaint fails to identify the terms of the contract with
    Lovelace that were breached or how Lovelace breached them. Although the facts
    underlying the contractual claim are not particularly well articulated, we cannot say
    that it fails the jurisdictional analysis. A court could reasonably infer from the
    complaint that the “contract” referred to involves the patient’s agreement that
    Lovelace will provide medical services at its facilities, including providing medical
    personnel to perform those services, in consideration of payment by the patient or his
    or her insurance company. As part of this contractual understanding with patients,
    Lovelace represented that it was an in-network provider, but it breached the
    “covenant of good faith and fair dealing,” see J.A., Vol. I at 43, by using medical
    personnel that it knew would overbill patients beyond in-network rates.
    Defendants assert that plaintiffs’ unjust enrichment claim fails against
    Lovelace because the complaint provides no factual basis to conclude that Lovelace
    retained any benefit from APP’s overbilling. For the reasons discussed concerning
    the conversion claim, supra, the allegations that Lovelace benefitted are sufficient, if
    only barely so.
    Finally, defendants assert that plaintiffs’ civil conspiracy claim fails against
    Lovelace because (1) the complaint alleges that Lovelace did not believe APP should
    be overbilling patients because such overbilling was barred by Lovelace’s contract
    24
    Appellate Case: 22-2057     Document: 010110710056        Date Filed: 07/13/2022       Page: 25
    with APP, and (2) the complaint fails to state any specific acts Lovelace took in
    furtherance of the alleged conspiracy. Taken in context, the cited allegations assert
    that Lovelace does not disclose to patients that they may end up paying more than in-
    network rates for APP’s employees’ services, because “ostensibly, Lovelace takes the
    position that such overbilling should not be taking place,” but that Lovelace
    nevertheless “benefits from APP’s overbilling.” Id. at 34. A reasonable inference
    from these provisions, taken as a whole, is that Lovelace has tacitly agreed to
    continue to represent itself as an in-network provider and to pursue its profitable
    arrangement with APP while turning a blind eye to APP’s overbilling practices,
    which are facilitated by Lovelace’s representations and contractual arrangements
    with patients and insurance companies. This conduct by Lovelace, including
    allegedly misleading omissions made to the public and to patients, facilitates the
    alleged conspiracy.
    In sum, to the extent a merits-based inquiry is appropriate when deciding the
    remand issue, we cannot say at this stage that plaintiffs’ complaint fails to seek
    significant relief from Lovelace. Finally, in considering Lovelace’s significance as a
    defendant, we must compare its conduct with that of the other defendant, APP. See
    Woods, 771 F.3d at 1266. For the reasons we have identified, Lovelace qualifies as a
    significant local defendant under this comparative analysis. Contrary to defendant’s
    contention, it does not appear that plaintiffs named Lovelace to defeat CAFA
    jurisdiction, or that Lovelace is not “actually a primary focus of the litigation.” Id. at
    1265.
