OPINION
GOULD, Circuit Judge:
This case involves a binding arbitration clause in a contract of adhesion between a commercial provider of highspeed, broadband Internet services and its customers. We consider the relationship of state and federal law and the concept of preemption in this context.
Dale Mortensen and Melissa Becker (“Plaintiffs”) brought this putative class action against Bresnan Communications alleging violations of the Electronic Communications Privacy Act, 18 U.S.C. §§ 2520-21, the Computer Fraud and Abuse Act, ,18 U.S.C. § 1030, and Mpntana state law for invasion of privacy and trespass to chattels in connection with targeted advertising that they received while using Bresnan’s Internet service. The service subscriber agreement provided to all Bresnan customers contained a choice-of-law clause, specifying that New York law should apply, and an arbitration clause, both of which the district court declined to enforce.
We consider, in light of the Supreme Court’s decision in
AT&T Mobility LLC v. Concepcion,
— U.S. —, 131 S.Ct. 1740, 179 L.Ed.2d 742 (2011), whether the Federal Arbitration Act (“FAA”), Pub.L. No. 68-401, 43 Stat. 883 (1925) (codified as amended at 9 U.S.C. §§ 1-2 et seq.), preempts Montana public policy invalidating adhesive agreements running contrary to the reasonable expectations of a party.
We then address the choice-of-law consequences flowing from that holding. We have jurisdiction pursuant to 9 U.S.C. § 16(a)(l)(A)-(B).
See Muriithi v. Shuttle Express, Inc.,
712 F.3d 173, 178 (4th Cir.2013);
Noohi v. Toll Bros., Inc.,
708 F.3d 599, 604 (4th Cir.2013).
Our decision turns on an interpretation of Concepcion’s meaning and breadth. After analyzing both
Concepcion
and subsequent cases, we conclude that
Concepcion
further limited the FAA’s savings clause, 9 U.S.C. § 2, and therefore hold (1) that the FAA preempts Montana’s reasonable expectations/fundamental rights rule and (2) that the district court erred in not applying New York law because a state’s preempted public policy is an impermissible basis on which to reject the parties’ choice-of-law selection. Consequently, we vacate the district court’s denial of Bresnan’s motion to compel arbitration and remand to the district court with instructions to apply New York law to the arbitration agreement.
I
We start with the facts giving rise to the dispute. Then we turn to the district court proceedings and present appeal.
A. The Facts Underlying Class Plaintiffs’ Claims
Plaintiffs, who reside in or near Billings, Montana, formerly subscribed to Internet services from Bresnan Communications, a franchised cable-television provider incorporated in Delaware, headquartered in New York, and operating in Montana, Colorado, Wyoming, and Utah. Class representative Dale Mortensen started services with Bresnan in October 2007. Bresnan has no record of a customer named Melissa Becker, although the company does not foreclose the possibility that she or another member of her household contracted for Internet service.
After customers subscribe to Bresnan’s services, technicians deliver a “Welcome Kit” to their homes and install the equipment necessary to activate the service. The “Welcome Kit” contains the Bresnan OnLine Internet Service Subscriber Agreement and Acceptable Use Policy (“service agreement”), which is also available on Bresnan’s website. On Page 21 of the 31-page service agreement, in bold, large font, is the heading “9. Arbitration.” Paragraph 9(a.) states:
Binding Arbitration.
ANY AND ALL DISPUTES ARISING BETWEEN CUSTOMER AND BRESNAN COMMUNICATIONS (WHETHER BASED IN CONTRACT, STATUTE, REGULATION, ORDINANCE, TORT — INCLUDING, BUT NOT LIMITED TO, FRAUD, ANY OTHER INTENTIONAL TORT OR NEGLIGENCE, — COMMON LAW, CONSTITUTIONAL PROVISION, RESPONDEAT SUPERIOR, AGENCY OR ANY OTHER LEGAL OR EQUITABLE THEORY), WHETHER ARISING BEFORE OR AFTER THE EFFECTIVE DATE OF THIS AGREEMENT, MUST BE RESOLVED BY FINAL AND BINDING ARBITRATION. THIS INCLUDES ANY AND ALL DISPUTES BASED ON ANY PRODUCT, SERVICE OR
ADVERTISING CONNECTED TO THE PROVISION OR USE OF THE SERVICE. The Federal Arbitration Act (“FAA”), not state law, shall govern the arbitrability of all disputes between Bresnan Communications and Customer regarding this Agreement and the Service. Bresnan Communications and Customer agree, however, that New York or federal law shall apply to and govern, as appropriate, any and all claims or causes of action, remedies, and damages arising between Customer and Bresnan Communications regarding this Agreement and the Service, whether arising or stated in contract, statute, common law, or any other legal theory, without regard to New York’s choice of law principles.
The substance of this paragraph has remained unchanged since 2003.
The beginning of the service agreement directs customers to, “Please read this Agreement very carefully, because by accepting the Service, you agree to all of these terms.”
In 2008, Bresnan entered into a temporary arrangement with advertising company NebuAd, Inc. Under the arrangement, in exchange for a share of NebuAd’s advertising revenue, Bresnan allowed NebuAd to place an appliance in its Billings, Montana, network. The appliance allowed NebuAd to gather information and create profiles of subscribers in order to target them with preference-sensitive advertising. Bresnan contends that it provided specific notice to consumers about the NebuAd trial and allowed individuals to opt out. Under a heading labeled “About Advanced Advertising,” the company website provided detailed information about the trial.
It also gave a list of thirteen frequently asked questions with corresponding answers that assured customers that no personally identifying information, such as first and last name, physical street address, email address, telephone numbers,
or social security numbers would be collected. Plaintiffs contend that this notice was misleading and that consent was never obtained.
B. The Facts Underlying Plaintiffs’ Appeal
After NebuAd’s temporary arrangement with Bresnan to gather information from the subscribers ended, a class of plaintiffs, including those involved in the present action, brought suit in the United States District Court for the Northern District of California against NebuAd and several Internet service providers who hosted NebuAd appliances, including Bresnan. Bresnan and the other providers moved to dismiss the action for lack of personal jurisdiction and failure to state a claim. The district court granted this motion finding personal jurisdiction lacking.
Valentine v. NebuAd, Inc.,
No. C08-05113 TEH, 2009 WL 8186130, at *3-10 (ND.Cal. Oct. 6, 2009). NebuAd became the sole defendant in that action and eventually reached a court-approved settlement with the plaintiffs.
But before reaching that settlement in the initial lawsuit, groups of plaintiffs filed new class actions in their respective states. Plaintiffs brought suit against Bresnan in the United States District Court for the District of Montana re-alleging violations of the Electronic Communications Privacy Act, 18 U.S.C. §§ 2520-21, and the Computer Fraud and Abuse Act, 18 U.S.C. § 1030, while also asserting state-law claims for invasion of privacy and trespass to chattels.
Bresnan responded by filing a motion to compel arbitration under the subscriber agreement and a motion to dismiss for failure to state a claim. In an opinion that did not address choice of law, the district court denied Bresnan’s motion to compel arbitration.
Mortensen v. Bresnan Commc’n, LLC,
No. CV 10-13-BLG-RFC, 2010 WL 4716744, at *3-4 (D.Mont. Nov. 15, 2010). The decision applied Montana public policy requiring arbitration agreements in contracts of adhesion to be within a party’s “reasonable expectations” and concluded that the arbitration agreement did not qualify because it amounted to unknowing waiver of the fundamental constitutional rights to trial by jury and access to courts.
Id.
Almost a month later, the court granted in part Bresnan’s motion to dismiss and discharged the Electronic Communications Privacy Act and Montana invasion-of-privacy claims.
Mortensen v. Bresnan Commc’n, LLC,
No. CV 10-13-BLG-RFC, 2010 WL 5140454, at *9 (D.Mont. Dec. 13, 2010).
Before discovery on the remaining Computer Fraud and Abuse Act claim and the state-law trespass-to-chattels claim, the Supreme Court decided
Concepcion.
Thereafter, Bresnan moved for and was granted leave to seek reconsideration of the denial of its motion to compel arbitration.
But in an order dated September 16, 2011, the district court concluded that although the Supreme Court’s characterization of the FAA in
Concepcion
“may impend doom for the Montana rules relied upon, it did not in itself kill them.” Interpreting
Concepcion’s
holding as further limiting the savings clause only with respect to unconscionability and class-waiver provisions, the court compared the arbitration agreement in the present case with the one invalidated under
Concepcion
and found that they differed in that the current provision (1) was not unconscionable and (2) was not void because it contained a class-action waiver. In sum, the court found that the Montana reasonable expectations/fundamental rights rule survived
Concepcion,
served as the fundamental public policy supporting the application of
Montana law (as opposed to New York law) under Montana choice-of-law rules, and required the court to deny arbitration.
Bresnan filed a timely appeal of that denial. It contends that the district court erred in finding that the Montana rule is not preempted by the FAA and, if preempted, New York choice of law should have applied, resulting in arbitration. Alternatively, Bresnan contends that after
Concepcion
an application of the Montana choice-of-law analysis does not justify rejection of New York law.

We review
de novo
a district court’s decision denying a motion to compel arbitration, including the interpretation of the validity and scope of the clause.
Bushley v. Credit Suisse First Bos.,
360 F.3d 1149, 1152 (9th Cir.2004);
see also Chiron Corp. v. Ortho Diagnostic Sys., Inc.,
207 F.3d 1126, 1130 (9th Cir.2000). As arbitration is favored, those parties challenging the enforceability of an arbitration agreement bear the burden of proving that the provision is unenforceable.
Green Tree Fin. Corp.-Ala. v. Randolph,
531 U.S. 79, 91, 121 S.Ct. 513, 148 L.Ed.2d 373 (2000). We also review
de novo
the district court’s decision concerning the appropriate choice of law.

68 F.3d 1160, 1167 (9th Cir.1995).
III
We first address whether the FAA preempts Montana’s reasonable expectations/fundamental rights rule and then address the choice-of-law consequences flowing from that conclusion.
A. Preemption of the Reasonable Expectations/Fundamental Rights Rule
The Supremacy Clause provides that “the Laws of the United States ... shall be the supreme Law of the Land.” U.S. Const, art. VI, cl. 2. And a state law that “stands as an obstacle to the accomplishment and execution of the full purposes and objectives of Congress” is preempted by the Supremacy Clause.
Hines v. Davidowitz,
312 U.S. 52, 67, 61 S.Ct. 399, 85 L.Ed. 581 (1941). We start with an explanation of the FAA, the Supreme Court’s
Concepcion
decision, and the Montana reasonable expectations/fundamental rights rule at issue in this case. We then apply
Concepcion
to the Montana rule to decide whether it is preempted.
1. The FAA
The FAA, enacted in 1925, facilitates private dispute resolution by making arbitration agreements in maritime transactions and in contracts involving interstate commerce presumptively “valid, irrevocable, and enforceable.”
See also Kilgore,
2013 WL 1458876, at *2 (quoting 9 U.S.C. § 2). The law was created to counter prevalent judicial refusal to enforce arbitration agreements,
Concepcion,
131 S.Ct. at 1745, and has been interpreted to embody “a liberal federal policy favoring arbitration,”
Moses H. Cone Mem’l Hosp. v. Mercury Constr. Corp.,
460 U.S. 1, 24, 103 S.Ct. 927, 74 L.Ed.2d 765 (1983). The FAA “mandates that district courts
shall
direct the parties to proceed to arbitration on issues as to which an arbitration agreement has been signed.”
Kilgore,
2013 WL 1458876, at
*2
(quoting
Dean Witter Reynolds, Inc. v. Byrd,
470 U.S. 213, 218, 105
S.Ct. 1238, 84 L.Ed.2d 158 (1985)). Thus the FAA gives a strong boost to arbitration.
See Kramer v. Toyota Motor Corp.,
705 F.3d 1122, 1126 (9th Cir.2013).
As federal substantive law, the FAA preempts contrary state law.
See Prima Paint Corp. v. Flood & Conklin Mfg. Co.,
388 U.S. 395, 400, 87 S.Ct. 1801, 18 L.Ed.2d 1270 (1967);
see also Concepcion,
131 S.Ct. at 1746. The FAA’s preemption power has an exception: It does not require the enforcement of arbitration agreements on “such grounds as exist at law or in equity for the revocation of any contract.” 9 U.S.C. § 2 (also known as the “savings clause”). This savings clause preserves generally applicable contract defenses, such as fraud, duress, or unconscionability, and ensures that they are not preempted.
See Kilgore,
2013 WL 1458876, at *3;
see also Concepcion,
131 S.Ct. at 1746.
Parties have often cited the savings clause in an attempt to defeat a motion to compel arbitration.
The United States Supreme Court has been moved to step in and stop some efforts to avoid FAA preemption, most notably in its
Concepcion
decision.
2. The
Concepcion
Decision and Its Progeny
Concepcion
addressed whether the FAA’s savings clause preempted a California state rule, known as the
Discover Bank
rule,
that invalidated the majority of class-action waivers in contracts of adhesion as unconscionable.
The facts involved a class of plaintiffs who purchased AT & T mobile service advertised as including a free phone.
Concepcion,
131 S.Ct. at 1744. Litigation resulted after plaintiffs were charged $30.22 in sales tax on the retail value of the phones.
Id.
The service contract signed by class members included a provision requiring all disputes to be arbitrated individually and not collectively.
Id.
In its opinion,' the Supreme Court reversed the Ninth Circuit’s decision in
Last-
er v. AT & T Mobility LLC,
584 F.3d 849, 853-59 (9th Cir.2009), which held that the FAA did not preempt the
Discover Bank
rule because
Discover Bank
was generally applicable and thus was within the FAA’s savings clause. Instead, the Supreme Court reasoned that even general contract defenses, such as unconscionability, are preempted if they “stand as an obstacle to the accomplishment” of “ensuring] that private arbitration agreements are enforced according to their terms.”
Concepcion,
131 S.Ct. at 1748 (quoting source omitted).
The Supreme Court acknowledged that the “inquiry becomes more complex when a doctrine normally thought to be generally applicable ... is alleged to have been applied in a fashion that disfavors arbitration.”
Id.
at 1747. But it concluded for the first time that even generally applicable state-law rules are preempted if in practice they have a “disproportionate impact” on arbitration or “interfere!] with fundamental attributes of arbitration and thus create!] a scheme inconsistent with the FAA.”
Id.
at 1747-48.
In
Marmet Health Care Center, Inc. v. Brown,
the Supreme Court put an exclamation point on the savings clause’s new limits that it had established in
Concepcion. See
— U.S. —, 132 S.Ct. 1201, 1203, 182 L.Ed.2d 42 (2012). In
Marmet
the Court held that the FAA preempted a West Virginia law invalidating arbitration clauses in nursing home admission agreements adopted before an occurrence of negligence resulting in a personal injury or wrongful death: “When state law prohibits ... the arbitration of a particular type of claim, the analysis is straightforward: The conflicting rule is displaced by the FAA.”
Id.
at 1203.
We interpret Concepcion’s holding to be broader than a restriction on the use of unconscionability to end-run FAA preemption. We take
Concepcion
to mean what its plain language says: Any general state-law contract defense, based in unconscionability or otherwise, that has a disproportionate effect on arbitration is displaced by the FAA. We find support for this reading from the illustration in
Concepcion
involving a case “finding unconscionable
or unenforceable as against public policy
consumer arbitration agreements that fail to provide for judicially monitored discovery.” 131 S.Ct. at 1747 (emphasis added). Other courts have read
Concepcion
in a similar way.
Some might argue that our interpretation of
Concepcion
goes too far beyond the initial purpose of the FAA, which was to eliminate judicial hostility toward arbitration and place arbitration provisions on “the same footing” as all other contractual provisions.
See Iwen,
977 P.2d at 994;
see also Supak & Sons Mfg. Co. v. Pervel Indus., Inc.,
593 F.2d 135, 137 (4th Cir.1979). But we follow the Supreme Court’s premise in
Concepcion
that the FAA’s purpose is to “ensur[e] that private arbitrations are enforced.” 131 S.Ct. at 1748 (quoting
Volt Info. Scis., Inc. v. Bd. of Trs. of Leland Stanford Junior Univ.,
489 U.S. 468, 474, 109 S.Ct. 1248, 103 L.Ed.2d 488 (1989));
see also Am. Express Co. v. Italian Colors Rest.,
— U.S. —, 133 S.Ct. 2304, 2312 & n. 5, 186 L.Ed.2d 417 (2013) (noting that
Concepcion
established that
“the FAA’s command to enforce arbitration agreements tramps any interest in ensuring the prosecution of low-value claims”). The word “ensure” is defined to mean “to make (one) sure (as by pledging, guaranteeing, convincing, or declaring)” or “to make sure, certain, or safe: GUARANTEE.” Webster’s Third New International Dictionary 756 (1993). In our view,
Concepcion
crystalized the directive, touched on in
Volt,
489 U.S. at 474, 109 S.Ct. 1248, that the FAA’s purpose is to give preference (instead of mere equality) to arbitration provisions. 131 S.Ct. at 1748.
Concepcion
outlaws discrimination in state policy that is unfavorable to arbitration by further limiting the savings clause. We are bound by our duty to apply
Concepcion
and do so here.
3. The Montana Reasonable Expectations/Fundamental Rights Rule
We apply
Concepcion to the
Montana reasonable expectations/fundamental rights rule to determine whether it is preempted by the FAA.
Under Montana state law, courts determining the validity of a contract begin with assessing whether the contract is one of adhesion.
Ticknor v. Choice Hotels Int’l, Inc.,
265 F.3d 931, 939 (9th Cir.2001);
Iwen,
977 P.2d at 995. This inquiry focuses on the contracting process to determine whether both parties had the ability to negotiate contract terms.
Iwen,
977 P.2d at 995. Finding that the contract was adhesive opens the door for an unconscionability or public policy defense.
Id.
Once a court views a contract as adhesive, it must examine the challenged provision to determine whether it is unconscionable or in violation of public policy.
Id.
A provision that was not in the reasonable expectations of both parties when contracting is void as against public policy.
Id.
(referring to
Passage v. Prudential-Bache Sec., Inc., 223
Mont. 60, 727 P.2d 1298, 1301 (1986)). As a matter of law, Montana finds involuntary waiver of fundamental constitutional rights to be outside of consumers’ reasonable expectations.
Kortum-Managhan,
204 P.3d at 698-99.
Because the Montana Supreme Court has held that arbitration agreements constitute a waiver of a party’s fundamental constitutional rights to trial by jury and access to courts, all arbitration agreements where waiver is not “voluntarily, knowingly, and intelligently” made are void as a matter of public policy.
Id.
at 699 (citations omitted). Montana law defines “voluntarily, knowingly, and intelligently” made as requiring a consumer to be informed of the consequences of a provision and to personally consent to waiver after receiving the proper information.
Id.
Under this generally applicable rule, only arbitration agreements explained to and initialed by consumers are valid and enforceable.
See id.
4. The Effect of
Concepcion
on the Reasonable Expectations/Fundamental Rights Rule
Bresnan first contends that the Montana reasonable expectations/fundamental rights rule is not preserved by the FAA’s savings clause because it is not generally applicable given that it depends on the unique nature of arbitration agreements.
Bresnan supports this assertion
by urging that, unlike other contract provisions, arbitration agreements implicate fundamental rights. It contends that, even without
Concepcion,
the rule is preempted. We disagree. Bresnan may be correct that the reasonable expectations/fundamental rights rule has a disproportionate impact on arbitration agreements. But the rule does not invalidate only those agreements. Many other types of agreements may be equally affected by the Montana rule. And contract provisions requiring bench trials waive the fundamental right to a jury trial. We cannot say that the fundamental-rights rule depends entirely on the nature of arbitration agreements.
Bresnan next contends that even if the doctrine is one of general applicability, it disproportionally affects arbitration agreements and thus is preempted by the FAA following
Concepcion.
We agree. The Montana reasonable expectations/fundamental rights rule arose from state court consideration of adhesive arbitration agreements,
see Kortum-Managhan,
204 P.3d at 698-700, and most of the rule’s applications have been to those provisions,
see, e.g., Ticknor,
265 F.3d at 931;
Kloss,
54 P.3d at 7-8. Courts, including this one, considering Montana’s public policy repeatedly refer to it in arbitration-specific terms.
See, e.g., Ticknor,
265 F.3d at 939 (“In the context of adhesion contracts, the Montana Supreme Court has determined expressly that it will not enforce an [unfair] arbitration clause.” (citing
Iwen,
977 P.2d at 996)). Because of this, we conclude that the reasonable expectations/fundamental rights rule runs contrary to the FAA as interpreted by
Concepcion
because it disproportionally applies to arbitration agreements, invalidating them at a higher rate than other contract provisions. We hold that the FAA preempts the Montana reasonable expeetations/fundamental rights rule as that rule is currently employed.
B. The Effect of Preemption on Choice-of-Law Considerations
Now that we have determined that the Montana reasonable expeetations/fundamental rights rule is preempted by the FAA, we assess the consequences that flow from that conclusion. Federal courts sitting in diversity use the choice-of-law rules of the forum state, in this case Montana, to make a choice-of-law determination.
See Zinser v. Accufix Research Inst., Inc.,
253 F.3d 1180, 1187 (9th Cir.2001);
see also Sparling v. Hoffman Constr. Co., Inc.,
864 F.2d 635, 641 (9th Cir.1988). Montana uses the Restatement (Second) of Conflict of Laws § 187(2), which finds a choice-of-law provision overcome where (1) Montana has a materially greater interest in the transaction than the
state whose law was selected by the parties and (2) application of the selected state’s law would be contrary to Montana’s public policy.
Ticknor,
265 F.3d at 937-38.
In assessing whether Montana has a materially greater interest in the transaction, Montana law considers the place of contracting; the place where the contract was negotiated; the place of performance; the location of the subject matter of the contract; and the domicile, residence, nationality, place of incorporation and place of business of the parties.
Id.
at 938;
see also Keystone, Inc. v. Triad Sys. Corp.,
292 Mont. 229, 971 P.2d 1240, 1242 (1998) (applying the five factors from the Restatement (Second) of Conflict of Laws § 188 to determine if Montana had a materially greater interest in the transaction). Here, after applying these factors, the district court correctly concluded that Montana had a materially greater interest than New York in the dispute. The contract was received by the consumers in Montana as part of their Welcome Kit, and the contract governed services provided in Montana to Montana residents. The subject matter of the contract and performance of it took place almost entirely in Montana.
But the second prong of the choice-of-law analysis, requiring an' application of New York law to be contrary to the fundamental public policy of Montana, is lacking. The parties have briefed the differences between New York and Montana policies with respect to the relative favor (or lack thereof) that they show to arbitration agreements. In the district court, the judge noted that this prong was fulfilled because “application of New York law would contravene the fundamental public policy of Montana in that fundamental rights would be waived without notice.” Because Montana’s reasonable expectations/fundamental rights rule is preempted, we conclude that it cannot serve as a basis for rejecting the choice-of-law selection of the parties. We have found no other policy, not preempted by the FAA, that would justify the application of Montana law. We hold that the district court should have applied New York law to the arbitration agreement.
IV
This is not an easy case as it requires us to interpret
Concepcion
and apply that law to an established Montana rule that governs the validity of contracts generally but has a disproportionate impact on arbitration agreements. Montana has an interest in protecting its consumers from unfair agreements, particularly those that force waiver of fundamental rights without notice. But the Supreme Court in
Concepcion
told us to hold that the FAA preempts all laws that have a disproportionate impact on arbitration agreements. Given this directive, we hold that the Montana reasonable expectations/fundamental rights rule is preempted by the FAA. Because (1) a state’s preempted public policy is an impermissible basis on which to reject the parties’ choice of law and (2) under Montana choice-of-law analysis, courts cannot ignore the law selection of the parties unless it would contravene a fundamental state policy, the district court erred in failing to apply New York law. We vacate the district court’s denial of Bresnan’s motion to compel arbitration and remand to the district court with instructions to apply New York law to the agreement.
VACATED AND REMANDED.
