¶ 1 Plаintiff/Appellee, Lobo Exploration Company (Lobo), sued DefendantyAppellant, Amoco Production Company (Amoco), alleging Amoco double-billed certain costs for oil and gas wells where Lobo was a working interest owner and Amoco the operator. Lobo moved to certify the matter as a class action. After a seven-day evidentiary hearing, the trial court issued an order certifying the class. The сlass was defined as follows:
All persons or entities who own or owned an interest in any drilling and spacing unit, secondary recovery unit, or other enhanced recovery unit or property, or in oil and gas wells wherein Amoco was or is the operator, and where Amoco (a) used allocation accounts, sometimes referred to as “functional location accountability codes” (“FLACS”) and/or “Operating Centers” to bill and collect indirect charges and/or (b) billed and collected charges for the services of supervisors above first line supervision.
Specifically excluded from the class are: (a) any and all Amoco offshore operated properties; (b) any forced pooled working interest, unless the force pooled working interest owner entered into a joint operating agreement that superseded the pooling order; (c) all claims for improper billing of charges prior to January 1, 1983; (d) all agencies, departments or instrumentalities *1050 of the United States of America; and (e) Conoco Inc. and other persons or entities whom Plaintiffs counsel is prohibited from representing under Rule 1.7 of the Oklahoma Rules of Professional Conduct.
Amoco appeals pursuant to 12 O.S.Supp.1997 § 993(A)(6). We affirm.
¶ 2 In order to certify a class, the trial court must find (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 those of the class, and (4) the representative parties will fairly and adequately protect the interests of the class. 12 O.S.1991 § 2023(A). In addition, it must find one of the alternative conditions of Subsection B of 12 O.S.1991 § 2023. “Class determination ... shоuld be made by the court in a practical and realistic manner, based on what is actually involved in the litigation. No mechanical formula exists which can be applied to all cases.”

¶ 3 Amoco first contends the trial court’s failure to evaluate and resolve differences in state laws violated mandates of the U.S. Supreme Court, due process guarantees of the U.S. Constitution, and Oklahoma choice of law requirements. It argues the trial court did exactly what the Kansas courts attempted and the U.S. Supreme Court rejected in
Phillips Petroleum Company v. Shutts (Shutts),
¶ 4 Phillips appealed to the Kansas Supreme Court, arguing the Kansas trial court (1) did not have personal jurisdiction over the absent class members under the minimum contacts requirement of
International Shoe Co. v. Washington,
¶ 5 However, it reversed to the extent the Kansas Supreme Court held Kansas law was applicable to all the transactions being adjudicated in the case. The Court quoted its opinion in
Allstate Ins. Co. v. Hague,
[Wjhile a State may, for the reasons we have previously stated, assume jurisdiction over the claims of plaintiffs whose principal contacts are with other States, it may not use this assumption of jurisdiction as an added weight in the scale when considering the permissible constitutional limits on *1051 choice of substantive law. It may not take a transaction with little or no relationship to the forum and apply the law of the forum in order to satisfy the procedural requirement that there be a “common question of law.” The issue of personal jurisdiction over plaintiffs in a class action is entirely distinct from the question of the constitutional limitations on choice of law; the latter calculus is not altered by the fact that it may be more difficult or more burdensome to comply with the constitutional limitations because of thе large number of transactions which the State proposes to adjudicate and which have little connection with the forum.
Kansas must have a “significant contact or significant aggregation of contacts” to the claims asserted by each member of the plaintiff class, contacts “creating state interests,” in order to ensure that the choice of Kansas law is not arbitrary or unfair. Given Kansas’ lack of “interest” in claims unrelated to that State, and the substantive conflict with jurisdictions such as Texas, we conclude that application of Kansas law to every claim in this case is sufficiently arbitrary and unfair as to exceed constitutional limits.

¶ 6 Amoco argues Shutts requires that a state court resolve conflict of laws issues before certifying a nationwide class. It asserts the trial court “decreed Oklahoma law as the governing law for the claims of a nationwide class of working interest owners” without examining state law conflicts and thereby violated the mandate of Shutts. In its order certifying the class, the trial court cited Shutts in ruling “Oklahoma is not precluded from applying its own law in a class action so long as it has a ‘significant contact or aggregation оf contacts’ to the claims asserted by each member of the plaintiff class such that application of the forum law is not arbitrary or unfair.” It found Amoco had “significant and numerous” contacts with Oklahoma, including maintaining corporate offices in Tulsa, Oklahoma for over thirty years, centralizing its nationwide joint interest billings at the Tulsa office, and directing complaints and audits regarding Amoco-operated properties nаtionwide to the Tulsa office. The trial court concluded “the nationwide class sought to be certified in this case does not violate fundamental principles of due process or exceed the jurisdictional bounds of the Court.” It then stated,
Although Amoco argues that inevitable conflicts of law will make a class action unmanageable, Amoco has failed to show an actual conflict of law that has a materiаl effect on this action. It is the defendants’ burdén to demonstrate the existence of a true conflict of law. Moreover, at the certification stage it is improper to decide which law applies. (Citations omitted.)
¶ 7
Shutts
contains no language requiring resolution of conflict of laws questions prior to certifying a class. To the contrary, the Supreme Court remanded the case without disturbing its class action status. While some courts viеw
Shutts
as requiring a determination of conflict of laws questions at the threshold of determining whether common issues of law predominate,

others consider that the minority view.

¶ 8 Amoco’s second and third contentions of error challenge the trial court’s finding common questions of law or fact predominate. Its fifth contention of error challenges the finding a nationwide class action is a superior method of adjudicating the controversy. Both these requirements arise from 12 O.S.1991 § 2023(B)(3).
¶ 9 The existence of common issues of law or fact is a requirement for class action certification under 12 O.S.1991 § 2023(A). One of the three alternative requirements of § 2023(B) is a finding that the common issues predominate and a class action is the superior mеthod for adjudicating the controversy. Because Oklahoma’s § 2023 “bears great similarity to the provisions of Rule 23, Federal Rules of Civil Procedure, we may resort to federal authority to shed light on its rationale.”
Mattoon v. City of Norman,
[Wjhile Rule 23(b)(3) is often considered in conjunction with the commonality requirement of Rule 23(a)(2), the focus of Rule 23(b)(3) is actually different. “Whereas (a)(2) addresses thе issue of whether Rule 23 has any applicability at all to the law suit, (b)(3) addresses the issue of whether Rule 23 certification will have practical utility in the suit, considering the facts, substantive law, procedural due process, and fundamental fairness.” ... Specifically, the predominance question under Rule 23(b)(3) requires the court to consider whether the group seeking class certification seeks to remedy a common legal grievance. (Citations omitted)
The Advisory Committee Notes to the 1966 Amendment of FRCP Rule 23 reflect Subsection (b)(3) was intended to encompass “those cases in which a class action would achieve economies of time, effort, and expense,” while excluding from class action status cases which “would degenerate in practice into multiple lawsuits separately tried.”
¶ 10 Here the trial court ruled,
Amoco treated all the non-operating working interest ownеrs the same with respect to the issues involved in this case, despite differing forms of agreements. The acts or omissions of Amoco which constitute the alleged breaches of contract and/or fraud, as well as the other causes of action pleaded by Lobo, are the same or similar acts or omissions for each class member. The court concludes, therefore, that common questions predominate where the acts or omissions are the same, even though damage amounts may vary.
It then found a class action was superior to any other available method for a fair and efficient adjudication of the controversy because the average claim of each of the more than 2,700 working interest owners was relatively small compared to the expense of litigating the claims. The trial court placed the burdеn on Amoco “to demonstrate the existence of a true conflict of law,” quoting
Lewis v. Sac and Fox Tribe of Oklahoma Housing Authority,
A.
¶ 11 On appeal, Amoco contends variations in state substantive law applicable to the claims of the nationwide class preclude
*1053
any finding of predominance. First, it argues Lobo bore the burden of establishing there are no conflicts between the laws of the various states at issue, citing federal authority.
3
Other federal and state courts have rejected such a requirement at the class certification stage.

In
Weatherly v. Deloitte & Touche,
¶ 12 Lobo’s petition raises alternative legal theories, including fraud, obtaining money through false pretenses and deceit, breach of contract, unjust enrichment, accounting, tortious/bad faith breach of contract, and violation of the Oklahoma Consumer Protection Act, to recovеr for damages arising from a single set of facts, to wit, that Amoco double-billed worldng interest owners by billing as direct costs items which were also included in the “combined fixed rate” overhead charge. The trial court’s finding the same acts or omissions of Amoco formed the basis of each class member’s claims is well supported by the evidence cited in its order.- For example, in its response to an audit exception letter by Lobо’s accounting expert, Amoco stated, “We have approximately 60 audits performed on Amoco operated properties each year, all of which receive charges in the same manner and using the same systems as those used to generate charges to this Unit.” Amoco’s former audit coordinator, J.D. Shearrer, testified Amoco relied on COPAS 5 agreements in determining what was chargeable to the joint account. He agreed Amoco gave a standard response to audit exceptions based on the COPAS provisions. In addition, Lobo entered into evidence an April 10,1995 meeting agenda of Amoco’s “COPAS Review Committee,” which showed Shearrer was to give a “[sjhort presentation on how we are ‘double dipping’ the joint account through charges to the O/C [Operations Center] account. This may provide a basis for cоmpromise if we have to negotiate settlement on some audits.” This record supports the trial court’s finding Amoco treated the class members uniformly with respect to the disputed charges. Accordingly, the trial court did not abuse its discretion in ruling common issues predominate.
¶ 13 Amoco argues the substantive law governing the common law claims contains “irreconcilable conflicts” that preclude any finding of predominance, but dоes not identify any such common law conflicts. It does identify differences among the states’ consumer fraud statutes and cites numerous cases for the proposition that application of multiple states’ consumer fraud or consumer protection laws creates such conflicts as to defeat predominance. However, in those cases the conduct complained of took place in multiple stаtes.
6
In another case cited by Amoco,
Martin v. Dahlberg,
*1054 Defendants have shown that true conflict exists among the various consumer protection laws of the various states; however, they have not shown that any state other than California has an interest in applying its own laws, nor have defendants attempted to meet their burden of establishing that the application of California law would impair the interests of any foreign state.
Here Lobo complains of Amoco’s conduct in Oklahoma. Oklahoma has an interest in redressing wrongs committed within the state.
7
Amoco has not shown any state other than Oklahoma has an interest in applying its consumer protection laws or that the application of Oklahoma’s Consumer Protection Act would impair the interests of another state. Similarly, Oklahoma may apply its own punitive damages law to punish unlawful conduct in Oklahoma and deter its repetition.
BMW of N. Am., Inc. v. Gore,
B.
¶ 14 Amoco next argues the trial court abused its discretion in certifying the class because individual issues are raised by certain elements of the claims and by its affirmative defenses. It contends (1) the class includes members “who knew about [Amoco’s] accounting procedures and accepted those charges,” and “who objectеd to Amoco’s accounting procedures and then settled and released their claims,” (2) each class member must show individual reliance on misrepresentations, and (3) the claims of many class members are barred by statutes of limitation, laches, waiver, and estoppel. In
Black Hawk v. Exxon,
This argument relates to the merits of the action, and inquiry into the merits is inappropriate whеn the court is deciding whether a class should be certified.
[[Image here]]
... Inability to prove reliance on defendants’ misrepresentations may ultimately defeat [plaintiffs’] claims but the mere possibility that their proof on this issue might fail is not grounds to deny certification of the class.... Nevertheless, in order to establish causes of action for fraud, at trial plaintiffs must prove all elements necessary to prove fraud, including their reliance on defendants’ representations.
Amoco’s arguments relate to the merits of its defenses. The trial court properly avoided reaching the merits of the action on a motion to certify a class.
C.
¶ 15 Amoco contends the trial court erred in finding a class action is a superior method of adjudicating the controversy because individual issues render a class action unmanageable. In determining the superiority of a class action, the trial court is required to balance “the benefits which the class action procedure has over other alternative methods of adjudicating the dispute ... against the management problems which may arise from class treatment.”
Shores v. First City Bank Corp.,
Ill
¶ 16 Amoco’s last contention of error is Lobo did not prove typicality or adequacy of representation. It argues the trial court ignored evidence that Lobo’s claims were ma *1055 terially distinct from and antagonistic to those of other class members.
¶ 17 The typicality requirement focuses on the similarity of the legal and remedial theories behind the class members’ claims.
Jenkins v. Raymark Indus., Inc.,
¶ 18 Amoco argues Lobo’s interests conflict with “many absent class members [who] have followed the same accounting and billing procedures alleged to have been fraudulent” by Lobo. The trial court ruled the evidence at hearing “did not reveal that Lobo has claims which are in any way antagonistic to the claims of members of the proposed class.” Amoco has not alleged or cited evidence Lobo has claims against other class members relating to the subject matter of this litigation, and no such claims appear “obvious and pervasive” in the record.
Marshall v. Holiday Magic, Inc.,
¶ 19 For the foregoing reasons, the trial court’s order certifying the class is AFFIRMED.
