COLLOTON, Circuit Judge.
ProEnergy Services, LLC, and its surety Western Surety Company (collectively, ProEnergy) appeal a judgment of the district court confirming an arbitrators award of attorneys fees and expenses to Beumer Corporation and Beumer Kansas City, LLC (collectively, Beumer). We conclude the arbitrator acted within the scope of his authority, and we therefore affirm.
Beginning in November 2011, Beumer and ProEnergy contracted for ProEnergy to furnish and fabricate steel as part of Beumers construction of a pipe conveyor system. Beumer complained, however, that ProEnergys work was deficient, and withheld payment to cover its alleged damages. The contract included an arbitration clause, and ProEnergy initiated an arbitration proceeding in response to Beumers refusal to pay. ProEnergy sought approximately $500,000 for the withheld payment, and Beumer counterclaimed for $2.3 million in damages.
During the arbitration proceedings, the parties disputed whether their contracts provision on limitation of liability was enforceable and the extent to which it limited ProEnergys liability. The provision states: Notwithstanding any of the foregoing or any other term in this Contract, the total liability of Contractor for any loss, indemnity, damage or delay of any kind will not under any circumstances exceed 100% of the Contract Sum.
The arbitrator determined that the provision was enforceable, and that the liability cap (the Contract Sum) was $699,702.39. The arbitrator, however, concluded that the limitation on liability did not extend to attorneys fees, and that an award of damages plus attorneys fees could exceed the cap. Citing four decisions-including one from this court-that applied law from Illinois, Texas, Arizona, and Florida, respectively, the arbitrator observed that [i]n the limitation of liability context, courts routinely classify attorneys fees and legal expenses not as damages but as costs that are not subject to the limitation of liability. The arbitrator ultimately awarded Beumer $699,702.39 in damages plus $191,680.14 in pre-judgment interest, 9% post-judgment interest, and $916,027.90 in attorneys fees and expenses.
Beumer moved in the district court to confirm the award. ProEnergy paid the damages award and the accompanying pre- and post-judgment interest, but moved to vacate the attorneys fees award as beyond the arbitrators authority under the contract. The district court confirmed the award, and ProEnergy appeals. We review the district courts legal conclusions de novo and its factual findings for clear error. Medicine Shoppe Intl, Inc. v. Turner Invs., Inc. , 614 F.3d 485, 488 (8th Cir. 2010).
Under the Federal Arbitration Act, 9 U.S.C. § 9, a court must confirm an arbitration award unless the award is vacated under 9 U.S.C. § 10, or modified or corrected pursuant to 9 U.S.C. § 11. Sections 10 and 11 set forth the exclusive grounds for vacating or modifying an award. See Hall Street Assocs., LLC v. Mattel, Inc. , 552 U.S. 576, 584, 128 S.Ct. 1396, 170 L.Ed.2d 254 (2008). ProEnergy seeks to vacate the attorneys fees award under § 10 on the ground that the arbitrator exceeded [his] powers. 9 U.S.C. § 10(a)(4).
An arbitrator does not exceed his powers by making an error of law or fact, even a serious one. The parties agreed that disputes would be finally determined by arbitration, and so long as the arbitrator is even arguably construing or applying the contract and acting within the scope of his authority, the award should be confirmed. Medicine Shoppe , 614 F.3d at 488 (quoting McGrann v. First Albany Corp. , 424 F.3d 743, 748 (8th Cir. 2005) ). ProEnergy does not dispute that the contract includes a valid attorneys fees provision, or that the arbitrator was arguably construing the limitation on liability provision when he determined that the provision did not extend to attorneys fees.
Nevertheless, ProEnergy contends the arbitrator exceeded his powers because he did not follow the contracts section on governing law. The provision specifies that [t]his Agreement will be subject to, governed by and construed in accordance with the laws of the State of Missouri, without giving effect to its conflict of law rules. Missouri law, ProEnergy asserts, considers attorneys fees to be loss or damage, so that any amount awarded for fees should count toward the limit of liability under the contract. ProEnergy urges that the arbitrator exceeded his powers when he disregarded the choice-of-law provision, cited cases applying the law of jurisdictions other than Missouri, and construed the provision limiting liability to exclude attorneys fees.
The face of the arbitrators decision does not support the assertion that he ignored the section on governing law. He did not, as ProEnergy suggests, specifically and expressly disregard[ ] an unequivocal choice-of-law provision. The arbitrator cited Missouri law throughout his order. He relied on Missouri law when assessing whether one version of the parties contract constituted a novation of a prior version. And he applied Missouri law to determine the applicable rate of pre- and post-judgment interest.
ProEnergy complains that the arbitrator did not cite Missouri decisions when addressing whether attorneys fees were covered by the limit on liability. The arbitrator, however, never said that he substituted his own choice-of-law preference for the contractual provision, and the absence of Missouri citations on this issue more likely suggests that the arbitrator found no Missouri authority on point. We follow a similar practice in diversity cases: when the State whose law we are applying has not addressed a particular issue, we turn to other jurisdictions for guidance. See Chicago Ins. Co. v. Archdiocese of St. Louis , 740 F.3d 1197, 1200 (8th Cir. 2014).
If the arbitrator mistakenly overlooked Missouri decisions that favored a contrary result, then he might have made an error of law in applying the contract, but such an error of law does not justify vacating the award. The parties bargained for the arbitrators decision; if the arbitrator got it wrong, then that was part of the bargain. Our own view is that the Missouri decisions cited by ProEnergy do not establish that attorneys fees are part of loss or damage under Missouri law, but whether the arbitrator was right or wrong by our lights is really beside the point.
ProEnergy cites authority from the Seventh Circuit that an arbitrators failure to apply the parties chosen law is a manifest disregard of the law that justifies vacating an award, but those decisions have been superseded. The Seventh Circuit itself recognized that ProEnergys preferred authority, see, e.g. , Edstrom Indus., Inc. v. Companion Life Ins. Co. , 516 F.3d 546, 552-53 (7th Cir. 2008), did not survive the Supreme Courts decision in Hall Street Associates , because manifest disregard of the law is not a ground on which a court may reject an arbitrators award under the Federal Arbitration Act. Affymax, Inc. v. Ortho-McNeil-Janssen Pharm., Inc. , 660 F.3d 281, 285 (7th Cir. 2011). We therefore conclude that ProEnergy has not demonstrated grounds to vacate the arbitration award under 9 U.S.C. § 10.
The judgment of the district court is affirmed. Beumers motion for sanctions is denied.
The Honorable Gary A. Fenner, United States District Judge for the Western District of Missouri.
