OPINION
The magistrate judge in this case vacated an arbitration award, finding that the arbitrator’s failure to reveal certain matters violated his “duty to disclose.” Because an arbitrator’s failure to disclose, in and of itself, provides no basis to vacate an award, and because the facts here do not demonstrate evident partiality by the arbitrator, we must reverse.
I.
This dispute arises from a coal sales contract between Cogentrix of North Carolina, Inc. and Coastal Coal Sales, Inc., the predecessor in interest of ANR Coal Company, Inc. (collectively “ANR”). Under this contract, Cogentrix agreed to purchase coal from ANR for Cogentrix’s Southport, North Carolina facility. Co-gentrix used the coal to generate electric power, which it, in turn, sold to Carolina Power & Light Co. Originally, Carolina Power agreed to purchase all of the electric power generated at the Cogentrix Southport facility. Cogentrix and Carolina Power renegotiated their agreement, however, to provide that Carolina Power was no longer obligated to purchase all of the electric power generated at that facility. For this reason, Cogentrix determined that it would have to reduce its electrical power output and, accordingly, sought to decrease its coal purchases from ANR. Asserting that Cogentrix’s attempt to reduce its purchases of coal violated the coal sales contract, ANR initiated arbitration to resolve the dispute.
The coal sales contract between Cogen-trix and ANR permitted each party to select one arbitrator, with the final arbitrator to be chosen by the other two arbitrators. Cogentrix and ANR each selected an arbitrator, but initially those arbitrators could not agree on a neutral third arbitra *496 tor. In accordance with the American Arbitration Association (AAA) Commercial Arbitration Rules, the AAA provided the parties with the names and qualifications of ten potential neutral arbitrators. Each side had three preemptory strikes and could also make challenges for cause. ANR objected to the list as too heavily weighted toward the utility industry, and specifically objected for cause to two potential arbitrators on the list. The AAA struck those two names from the list, as well as one name to which Cogentrix objected, and replaced them with three new names, including Wilburn Brewer, a partner at the Columbia, South Carolina law firm of Nexsen, Pruet, Jacobs & Pollard.
ANR then asked that Brewer be removed from the list for cause because his law firm represented Carolina Power. The AAA refused to take Brewer off the neutral list explaining that, although Brewer’s firm represented Carolina Power in “electrocution cases ... which are sporadically filed,” Brewer himself “never personally represented” Carolina Power. ANR used its three preemptory strikes, but chose not to strike Brewer. Each party then ranked the ten potential neutral arbitrator candidates; Brewer, the individual with the highest average ranking, was chosen as the neutral arbitrator.
In its December 19, 1996 letter announcing Brewer’s selection as the neutral arbitrator, the AAA listed the following disclosures by Brewer:
In 1987, his firm merged with Moore & Van Allen [the firm representing Cogen-trix at arbitration and on appeal] and then separated in 1988. During 1988, Mr. Brewer was ill with leukemia and not actively practicing law or involved with the firm. Through this temporary merger, Mr Brewer knows Mr. Davis [counsel in this matter for Cogentrix]. Mr. Brewer is confident that this will not affect his ability to impartially hear and determine this dispute.
Unless we are advised to the contrary by January 15,1997, we will assume that the Parties waive any presumption of bias by the Arbitrator based on this disclosure.
ANR did not renew its request to remove Brewer.
Two months later, on February 13, 1997, the AAA sent a letter to the parties addressing scheduling; an enclosure in that letter included another, similar disclosure signed by Brewer and again stated that the failure of a party to respond by a certain date (February 24) would constitute a waiver of any presumption of bias based on the disclosure. Again, ANR did not renew its request to remove Brewer. ANR maintains that it declined to object to Brewer because “[g]iven there was no assurance the challenge would be granted, a failed challenge could potentially offend the ‘neutral’ arbitrator as a challenge to his integrity.”
The arbitrators ruled 2-1 for Cogentrix, with Brewer in the majority. ANR contends that, after the arbitration award, it learned that Brewer’s law firm had represented Carolina Power in cases involving the utility’s right to deliver electric service, “contrary to the earlier disclosures ... that his firm only represented [Carolina Power] in electrocution cases.” Furthermore, ANR learned that Moore & Van Allen, the law firm that represented Co-gentrix in the arbitration, had also represented Cogentrix in 1988 when Moore & Van Allen was merged with Nexsen Pruet, and that in 1983 certain attorneys at Moore & Van Allen had loaned money to Cogentrix in consideration for stock warrants in the company.
ANR filed a civil complaint asking the court to vacate the arbitration award, which the magistrate judge promptly did.

*497
order vacating an arbitration award.
See Consolidation Coal Co. v. Local 1643, United Mine Workers of America,
ANR maintains that two rationales support vacatur of the arbitration award. We discuss each in turn.
II.
First, and principally, ANR contends that Brewer’s failure to disclose the full extent of his relationship to Cogentrix constitutes a basis for vacating the arbitration award. The magistrate judge apparently agreed, reasoning that Brewer violated his “duty to disclose all information regarding his present and past relations with Cogen-trix and other interested parties.”
. Section 10 of the Federal Arbitration Act, 9 U.S.C. § 10 (1994) (the FAA), lists the grounds that may form the basis for vacatur of an arbitration award. These include proof that an award was procured by fraud, corruption, or undue means, or resulted from an arbitrator’s evident partiality, corruption, misconduct, or the like. See 9 U.S.C. §§ 10(a)(l)-(3). The statute makes no mention of an arbitrator’s failure to disclose information as a basis for vacating ah arbitration award.
Implicitly recognizing the lack of statutory authority for vacating an award based on a failure to disclose, ANR rests its argument on the AAA Commercial Arbitration Rules, which the coal sales contract provides govern the arbitration here. 2 Specifically, ANR contends that Brewer’s failure to disclose violated AAA Rule 19 and that this violation requires vacatur of the arbitration award.
Rule 19 provides:
Any person appointed as neutral arbitrator shall disclose to the AAA any circumstance likely to affect impartiality, including any bias or any financial or personal interest in the result of the arbitration or any past or present relationship with the parties or their representatives. Upon receipt of such information from the arbitrator or another *498 source, the AAA shall communicate the information to the parties and, if it deems it appropriate to do so, to the arbitrator and others.
AAA Commercial Arbitration Rule 19 (1996) (emphasis added). The language of this Rule does not require a potential arbitrator to disclose every interest or relationship with a party that could conceivably be regarded as a basis for bias. Rather, it only requires disclosure of an interest or relationship “likely to affect impartiality.” Even so, ANR contends that Rule 19 imposes a “mandatory nondis-cretionary” disclosure duty on an arbitrator, that Brewer violated this duty, and that this violation requires vacatur of the arbitration award.
ANR relies heavily on
Commonwealth Coatings Corp. v. Continental Casualty Co.,
ANR misinterprets
Commonwealth Coatings.
In that case, the Supreme Court made its strong statements as to the importance of disclosure in a context far different from that involved here. In
Commonwealth Coatings,
the arbitrator had kept secret “a repeated and significant” relationship that existed “over a period of four or five years” with one of the parties, which resulted in the party paying the arbitrator $12,000 in professional fees.
Rather, the
Commonwealth Coatings
Court observed that a less onerous obligation sufficed: “[w]e can perceive no way in which the effectiveness of the arbitration process will be hampered by the simple requirement that arbitrators disclose to the parties
any dealings that might create an impression of possible bias.” Id.
at 149,
Failure to disclose the sort of attenuated, nonsubstantial relationships at issue here violates neither the teaching of
Commonwealth Coatings
nor AAA Rule 19. As Judge Posner (citing Justice White’s concurrence) observed in a similar situation, to hold that Rule 19 “requires disclosure of every former social or financial relationship with a party or a party’s principals” would make it “impractical for persons in the business world to be arbitrators, thereby depriving the parties of the services of those who might be best informed and qualified to decide particular types of cases.”
Merit Ins. Co. v. Leatherby Ins. Co.,
Even if Brewer’s failure to disclose had violated Rule 19, that would not, by itself, require or even permit a court to nullify an arbitration award. When parties agree to be bound by the AAA rules, those rules do not give a federal court license to vacate an award on grounds other than those set forth in 9 U.S.C. § 10. Thus, although the AAA rules provide significant and helpful regulation of the arbitration process, they “are not the proper starting point for an inquiry into an award’s validity.”
Merit,
None of the cases upon which ANR relies hold to the contrary.
Health Services Management Corp. v. Hughes,
Not only does precedent thus compel our rejection of ANR’s contention, but sound policy also counsels this result. Parties value commercial arbitration, at least in part, because they “prefer a tribunal knowledgeable about the subject matter of their dispute to a generalist court with its austere impartiality but limited knowledge of subject matter.”
Merit,
In sum, we hold that an arbitrator’s failure to reveal facts may be relevant in determining evident partiality under 9 U.S.C. § 10(a)(2), but that mere nondisclosure does not in itself justify vacatur.
III.
Alternatively, ANR maintains that Brewer’s failure to disclose demonstrates his “evident partiality” and for this reason provides grounds for vacatur under 9 U.S.C. § 10(a)(2). The party seeking va-catur has the burden of proof; to meet this burden, he must demonstrate “that a reasonable person would have to conclude that an arbitrator was partial to the other party to the arbitration.”
Consolidation Coal,
A court should examine four factors to determine if a claimant has demonstrated evident partiality: (1) the extent and character of the personal interest, pecuniary or otherwise, of the arbitrator in the proceeding; (2) the directness of the relationship between the arbitrator and the party he is alleged to favor; (3) the connection of that relationship to the arbitration; and (4) the proximity in time between the relationship and the arbitration proceeding. See id. at 130. Although the magistrate judge outlined this standard, he failed to apply it properly. Instead, relying on Brewer’s failure to disclose, the judge conclusorily held that “a reasonable person might conclude that Mr. Brewer might be inclined to rule in favor of Cogen-trix.”
In determining whether a party has demonstrated evident partiality,a court should evaluate the facts in light of each of the above four factors. When considering each factor, the court should determine whether the asserted bias is “direct, definite and capable of demonstration rather than remote, uncertain or speculative” and whether the facts are sufficient to indicate “improper motives on the part of the arbitrator.”
Consolidation Coal,
ANR contends that Brewer’s failure to disclose two sets of facts demonstrates his evident partiality. 5 We apply the four-factor test to each.
First, ANR points to the representation of Carolina Power in electric service cases by Brewer’s firm—Nexsen Pruet. ANR maintains that if the arbitrators had determined that Cogentrix breached the coal sales contract, then Co-gentrix would have passed the costs of this breach on to its sole customer, Carolina Power. Brewer, according to ANR, thus had a “personal interest” in finding no breach, i.e., protecting his firm’s client, Carolina Power, from incurring these costs.
ANR proffered no direct or definite evidence of this personal interest; no evidence that the contractual relationship between Carolina Power and Cogentrix required, or permitted, these costs to be passed on to Carolina Power; and no evidence that even if this happened it would have affected Carolina Power’s relationship with Nexsen Pruet. Furthermore, the claim that these facts demonstrate Brewer’s personal interest in Cogentrix is severely undercut by ANR’s pre-award willingness to accept Brewer despite its knowledge that Nexsen Pruet represented Carolina Power in electrocution cases. To be sure electrocution cases involve a different subject matter and perhaps a different expertise than electric service cases, but in both situations Carolina Power, the asserted indirect beneficiary of Brewer’s arbitration decision, was a client of Brewer’s firm, Nexsen Pruet. In sum, ANR has failed to offer evidence that Brewer had any “personal interest” in the arbitration.
See Cook Indus., Inc. v. C. Itoh & Co.,
Similarly, ANR has not demonstrated that Nexsen Pruet’s representation of Carolina Power evidences any “direct” relationship between Brewer and Cogentrix. Nor can ANR point to any real “connection” between that relationship and the arbitration. Carolina Power was not a party to the arbitration; Nexsen Pruet’s representation of the utility is thus a step removed from the arbitration proceeding. In
United States Wrestling Fed’n v. Wrestling Division of AAU, Inc.,
The second series of facts upon which ANR relies dates back to 1983. At that time certain attorneys with Moore & Van Allen lent money to Cogentrix, and in exchange they received stock warrants that permitted them to acquire, collectively, a six percent equity interest in Cogentrix. Thus when Nexsen Pruet briefly merged with Moore & Van Allen in 1988, some members of the consolidated firm, which represented Cogentrix, owned a small interest in Cogentrix. The third factor- — connection to the arbitration — may weigh in ANR’s favor in this instance because the arbitrator’s merged firm assertedly once represented one of the parties (rather than an alleged third party beneficiary) and some members of that firm owned a small ownership interest in that party. The other factors, however, clearly do not.
Indeed, it is difficult to understand how the facts of this case demonstrate any “personal interest” on Brewer’s part, let alone one that is direct and proximate in time to the arbitration.
See Al-Harbi v. Citibank, N.A,
ANR has not carried its burden of proffering facts that, alone or taken together, would permit a reasonable person to assume that Brewer was partial to Co-gentrix. A trivial relationship, even if undisclosed, will not justify vacatur of an arbitration award. The facts here demonstrate nothing more than a trivial relationship between Brewer and the prevailing party, Cogentrix.

For the foregoing reasons, we reverse the magistrate judge’s vacatur of the arbitration award and remand the case with instructions to reinstate the award.
REVERSED AND REMANDED.
Notes
. The Federal Arbitration Act (the FAA) requires ”[n]otice of a motion to vacate, modify, or correct an arbitration award must be served upon the adverse party or his attorney within three months after the award is filed or delivered.” 9 U.S.C. § 12 (1994). ANR
*497
served a civil complaint in this case, seeking to vacate the arbitration award, within three months of the filing of the award. But Co-gentrix maintains that ANR’s failure to serve notice of a
motion
to vacate “forfeits [ANR’s] right to judicial review of the award.” The FAA sets forth the sole method to challenge an arbitration award — “by serving a motion to vacate within three months of the rendering of the award,”
Taylor v. Nelson,
. ANR also briefly relies on Canon II of the AAA Code of Ethics for Arbitrators in Commercial Disputes. Canon II states that "arbitrators should disclose the existence of interests or relationships that are likely to affect their impartiality or that might reasonably create an appearance that they are biased against one party” and should "make a reasonable effort to inform themselves of any interests or relationships described in the preceding paragraph.” Even if Brewer violated Canon II (and it is not at all clear that he did), the Code of Ethics itself forecloses any use of such a violation as a basis for vacatur. The Preamble of the Code specifically states that "it does not form part of the arbitration rules of the [AAA]” and "does not establish new or additional grounds for judicial review of arbitration awards.”
. Because the vote of either Justice White or Justice Marshall was necessary to create a majority, courts have given this concurrence particular weight.
See, e.g., Peoples Security Life Ins. Co. v. Monumental Life Ins. Co.,
. The
Schmitz
court also stated that an arbitrator may have an "enhanced duty to investigate” potential facts that might be relevant to his bias, but this was in the context of an arbitration conducted under the more demanding rules of the National Association of Security Dealers, which require an arbitrator to "make such an investigation regarding the actual parties to th[e] arbitration.”
. Cogentrix argues that ANR waived its right to contest the impartiality of the arbitrator when it failed to assert a second challenge for cause after Brewer’s initial disclosures. Normally, such a failure might preclude a party from challenging the impartiality of the arbitrator.
