    14   Before:     SACK and LIVINGSTON, Circuit Judges, and MURTHA,
    15               District Judge.*
    16               Appeal from a decision of the United States District
    17   Court for the Southern District of New York (Shira A. Scheindlin,
    18   Judge) granting a petition to vacate an arbitral award under the
    19   Federal Arbitration Act on the basis of "evident partiality."           9
    
    20 U.S.C. § 10
    (a)(2).      The district court concluded that vacatur was
    21   warranted because two of the three members of the arbitral panel
    22   failed to disclose their simultaneous service as arbitrators in
    23   another proceeding in which a common witness, similar legal
    24   issues, and a related party were involved.           We conclude that
    *
    The Honorable J. Garvan Murtha, of the United States
    District Court for the District of Vermont, sitting by
    designation.
    1   there was insufficient evidence before the district court on
    2   which to base a finding of "evident partiality."   We therefore
    3   reverse and remand with instructions to confirm the arbitral
    4   award.

    21                            Respondents-Appellants.
    22   SACK, Circuit Judge:
    23             The primary question presented on this appeal is
    24   whether the failure of two arbitrators to disclose their
    25   concurrent service as arbitrators in another, arguably similar,
    26   arbitration constitutes "evident partiality" within the meaning
    27   of the Federal Arbitration Act (the "FAA"), 
    9 U.S.C. § 10
    (a)(2).
    28   Respondents Saint Paul Fire and Marine Insurance Company; St.
    29   Paul Reinsurance Company, Limited; and St. Paul Re Limited
    30   (collectively, "St. Paul") appeal from a decision of the United
    31   States District Court for the Southern District of New York
    32   (Shira A. Scheindlin, Judge) granting a petition by Scandinavian
    33   Reinsurance Company Limited ("Scandinavian") to vacate an
    34   arbitral award rendered in St. Paul's favor and denying a cross-
    2
    1   petition by St. Paul to confirm the same award.    St. Paul had
    2   initiated the arbitration (the "St. Paul Arbitration") to resolve
    3   a dispute concerning the interpretation of the parties'
    4   reinsurance contract.
    5             In deciding that vacatur was warranted on "evident
    6   partiality" grounds, the district court relied principally on the
    7   fact that two of the three members of the arbitral panel in the
    8   St. Paul Arbitration -- Paul Dassenko and Peter Gentile -- had
    9   failed to disclose that they were simultaneously serving as panel
    10   members in another arbitration proceeding: the "Platinum
    11   Arbitration."    The court observed that the Platinum Arbitration
    12   "overlapped in time, shared similar issues, involved related
    13   parties, [and] included . . . a common witness."    Scandinavian
    14   Reins. Co. v. St. Paul Fire & Marine Ins. Co., 
    732 F. Supp. 2d 15
       293, 307-08 (S.D.N.Y. 2010) ("Scandinavian") (footnotes omitted).
    16   The district court determined that "these factors indicate that
    17   Dassenko and Gentile's simultaneous service as arbitrators in
    18   [both proceedings] constituted a material conflict of interest."
    19   
    Id. at 308
    .     The court then concluded that the arbitrators'
    20   failure to disclose this conflict of interest required vacatur of
    21   the arbitral award.
    22             We disagree.     Evident partiality may be found only
    23   "'where a reasonable person would have to conclude that an
    24   arbitrator was partial to one party to the arbitration.'"
    25   Applied Indus. Materials Corp. v. Ovalar Makine Ticaret Ve
    26   Sanayi, A.S.,

    2   Dist. Council Carpenters Benefits Funds, 
    748 F.2d 79
    , 84 (2d Cir.
    3   1984)).     We conclude that, under the circumstances of this case,
    4   the fact of Dassenko's and Gentile's overlapping service as
    5   arbitrators in both the Platinum Arbitration and the St. Paul
    6   Arbitration does not, in itself, suggest that they were
    7   predisposed to rule in any particular way in the St. Paul
    8   Arbitration.     As a result, their failure to disclose that
    9   concurrent service is not indicative of evident partiality.      We
    10   therefore reverse and remand with instructions to the district
    11   court to confirm the award.
    12                                 BACKGROUND
    13                The facts are recited at length in the district court's
    14   opinion, see Scandinavian, 732 F. Supp. 2d at 295-302, and we
    15   borrow freely from that description here.    The facts are
    16   undisputed unless otherwise noted.
    17                The Reinsurance Contracts
    18                On August 21, 1999, Scandinavian and St. Paul -- both
    19   reinsurance companies -- entered into a specialized type of
    20   reinsurance contract known as a stop-loss retrocessional
    21   agreement.1    See Retrocessional Casualty Aggregate Stop Loss
    1
    The district court explained:
    Reinsurance is insurance for insurance companies[.]
    [T]he ceding company transfers or "cedes" all or part of
    the risk it underwrites to the reinsurer -- another
    insurance company that is willing to assume that risk.
    In a retrocessional agreement, a reinsurer cedes a
    portion of its risk to another reinsurer. A
    4
    1   Agreement AR 11914 (the "Agreement")).   Under the Agreement, St.
    2   Paul ceded to Scandinavian some of the reinsurance liabilities
    3   that St. Paul had assumed from other insurance companies under
    4   reinsurance business that had been, or would be, written by St.
    5   Paul between January 1, 1999, and December 31, 2001.
    6             In exchange for Scandinavian's assumption of these
    7   liabilities, St. Paul became obligated to pay premiums to
    8   Scandinavian.   But the Agreement contemplated that instead of
    9   paying the premiums to Scandinavian directly, St. Paul would
    10   provisionally retain those funds within an "experience account,"2
    11   where the funds would accumulate interest.   Any amounts that
    12   Scandinavian became obligated to pay St. Paul based on the
    13   assumed liabilities would first be paid out of that account.
    14   Only if the experience account became fully depleted would
    15   Scandinavian have to pay St. Paul out of its own funds.
    16             The Agreement contained a dispute-resolution clause
    17   providing for binding arbitration of "any dispute arising out of
    18   the interpretation, performance or breach of this Agreement,
    19   including the formation or validity thereof."   Agreement at 11.
    retrocessional agreement is effectively reinsurance for
    reinsurance.

    generally Unigard Sec. Ins. Co. v. N. River Ins. Co., 
    4 F.3d 1049
    , 1053-54 (2d Cir. 1993) (describing the reinsurance
    business).

    Although termed an "account," the experience account is a
    purely notional bookkeeping concept.
    5
    1   It required that such disputes be "submitted for decision to a
    2   panel of three arbitrators" -- two party-appointed arbitrators
    3   and an umpire -- all of whom would be "disinterested active or
    4   former executive officers of insurance or reinsurance companies
    5   or Underwriters at Lloyd's, London."    
    Id.
    6               Emergence of the Parties' Dispute
    7               In January 2002, Scandinavian entered into "run-off,"3
    8   thereby ceasing to underwrite new business.     St. Paul also
    9   entered into run-off later the same year.
    10               After St. Paul requested that Scandinavian indemnify it
    11   for much of its loss, two disputes emerged between the parties
    12   concerning the Agreement's interpretation.      First, the parties
    13   could not agree on whether they had intended the Agreement to
    14   limit the volume of liability assumed by Scandinavian.
    15   Scandinavian argued that the parties had intended the Agreement
    16   to be "finite," and that the maximum possible loss to
    17   Scandinavian that the parties had contemplated was about $21
    18   million.4   St. Paul contended, however, that the Agreement
    19   contained no express limitation on the extent of risk that
    3
    According to the parties, a reinsurer is said to be in
    "run-off" status when it ceases to write new reinsurance
    contracts but continues to administer its existing obligations
    under previously issued contracts. It is essentially an "orderly
    wind-down" of the company's reinsurance business. Delta
    Holdings, Inc. v. Nat'l Distillers & Chem. Corp., 
    945 F.2d 1226
    ,
    1235 (2d Cir. 1991), cert. denied, 
    503 U.S. 985
     (1992).
    4
    Scandinavian also contends that, conversely, the maximum
    possible gain to Scandinavian that the parties had contemplated
    was $3 million.
    6
    1   Scandinavian had assumed and that no such limitation should be
    2   read into the Agreement.    St. Paul ultimately sought to charge
    3   Scandinavian with losses of approximately $290 million.
    4             Second, the parties could not agree on whether the
    5   Agreement provided for a single experience account, or instead
    6   three separate experience accounts (i.e., one for each year
    7   covered by the Agreement).   Scandinavian argued that the
    8   Agreement provided for one, while St. Paul argued that there were
    9   three separate accounts.
    10             The Arbitrators and Their Disclosures
    11             To resolve these disputes, in September 2007, St. Paul
    12   demanded arbitration.   In accordance with the terms of the
    13   Agreement, the parties proceeded to select the three members of
    14   the arbitral panel.   Scandinavian appointed Jonathan Rosen, and
    15   St. Paul appointed Peter Gentile.     Paul Dassenko was selected to
    16   serve as umpire.5   The parties accepted Dassenko's appointment on
    17   November 29, 2007, following their receipt of his responses to a
    18   disclosure questionnaire.
    5
    The parties' descriptions regarding who was responsible
    for selecting Dassenko appear to be inconsistent. St. Paul
    states that each party proposed five possible candidates for
    umpire, and that Dassenko was jointly selected by the parties
    because he had been included on each party's list. Scandinavian
    states, instead, that the two party-appointed arbitrators, Rosen
    and Gentile, were the ones responsible for selecting Dassenko.
    The district court, without noting this inconsistency, accepted
    Scandinavian's representation that "Rosen and Gentile selected
    Paul Dassenko to be the umpire." Scandinavian, 732 F. Supp. 2d
    at 296. There is no need to inquire further into this matter,
    however, because it does not affect the outcome on appeal.
    7
    1              Although the Agreement did not require the arbitrators
    2   to be affiliated with any particular arbitral association, all
    3   three arbitrators were certified by the AIDA Reinsurance and
    4   Insurance Arbitration Society ("ARIAS").   ARIAS has promulgated
    5   ethical guidelines for certified arbitrators, including Canon IV,
    6   which instructs arbitrators to "disclose any interest or
    7   relationship likely to affect their judgment" and to resolve any
    8   doubt about whether to disclose "in favor of disclosure."   ARIAS
    9   U.S., Code of Conduct - Canon IV,
    10   http://www.arias-us.org/index.cfm?a=30 (last visited Dec. 20,
    11   2011).   In accordance with those guidelines, each of the
    12   arbitrators made initial disclosures to the parties.    The form of
    13   those disclosures differed.
    14             Dassenko, the umpire, responded in writing to a nine-
    15   page questionnaire jointly submitted by the parties.6   See [J.A.
    16   112-30] Umpire Questionnaire (Nov. 21, 2007).   In addition to
    17   disclosing his past employment at several firms affiliated with
    18   either St. Paul or Scandinavian,7 Dassenko noted that it was
    19   "likely" that he had "transacted or sought to transact business
    6
    The questionnaire appears to have been modeled on a
    sample disclosure form prepared and disseminated by ARIAS. See
    ARIAS U.S., Arbitrators/Umpire Questionnaire,
    http://www.arias-us.org/forms/arias-arbitrator-umpire-disclosure-
    questionaire.doc (last visited Dec. 20, 2011).
    7
    The parties' questionnaire identified some fifty-eight
    entities within the "Travelers Group of Insurance Companies," to
    which St. Paul belongs, and some sixty-two entities within the
    "White Mountains Insurance Group Companies," to which
    Scandinavian belongs. See Umpire Questionnaire ¶ 6(A).
    8
    1   with most of the entities" listed by the parties on the
    2   questionnaire, including St. Paul and Scandinavian themselves.
    3   Id. ¶ 6(c).    Dassenko represented, however, that he had never had
    4   any involvement with the subject matter of the dispute, nor did
    5   he have any significant professional or personal relationship
    6   with any officers, directors, or employees of the parties.8
    7   Dassenko also indicated that he had previously served as an
    8   arbitrator in more than 150 insurance or reinsurance
    9   arbitrations, including two arbitrations in which Rosen had also
    10   been an arbitrator.    At the prompting of St. Paul's counsel,
    11   Dassenko made additional disclosures by email on November 27,
    12   2007, with respect to certain matters that he had forgotten to
    13   include in responding to the questionnaire.
    14               The two party-appointed arbitrators made their initial
    15   disclosures orally at an organizational meeting held on February
    16   25, 2008.   Both Rosen, the Scandinavian-appointed arbitrator, and
    17   Gentile, the St. Paul-appointed arbitrator, made a variety of
    18   disclosures about past and present employment, their
    19   relationships to the parties or their law firms, and their
    20   participation as witnesses or arbitrators in other proceedings
    8
    In the context of describing the umpire questionnaire, the
    district court noted that "Dassenko did not mention working with
    Gentile on any arbitration nor did he disclose any relationship
    with Platinum." Scandinavian, 732 F. Supp. 2d at 297. We note
    that it would have been impossible for Dassenko to have made
    those specific disclosures at that time, however, because the
    Platinum Arbitration did not begin until more than six months
    later.
    9
    1   involving the same parties, their affiliates, their law firms, or
    2   the same arbitrators.9
    3              After Rosen and Gentile made their respective
    4   disclosures, Dassenko -- speaking on behalf of the panel --
    5   "urge[d] [the parties] to . . . determine whether there's
    6   anything else that deserves more attention in terms of
    7   disclosures on behalf of this [p]anel."      Tr. at 15 (Feb. 25,
    8   2008).   Dassenko also acknowledged, on behalf of the panel, the
    9   arbitrators' "ongoing responsibility" to make disclosure if and
    10   when they "become aware of relationships or situations that
    11   require additional disclosure."    Id.     The parties agreed to
    12   accept the panel as constituted.       They did not ask any other
    13   questions relating to the arbitrators' disclosures at that time.
    14              As the St. Paul Arbitration progressed, the arbitrators
    15   made various additional disclosures.      On July 18, 2008, Gentile
    16   informed the parties that during the time he worked at a
    17   specified firm, other staff members at that firm might have
    18   reviewed the same contract that was at issue in the St. Paul
    19   Arbitration.   During a motion hearing held on May 2, 2009, he and
    20   Rosen disclosed that they had known Scandinavian's expert witness
    21   professionally and personally for many years.      And on June 23,
    22   2009, Gentile told the parties that he had met one of
    9
    For example, Gentile disclosed that he had previously
    appeared as a fact witness in an arbitration in which Dassenko
    was a party arbitrator and in which the opposing party was an
    affiliate of Scandinavian.
    10
    1   Scandinavian's witnesses, Bart Hedges, "a few times in the past,
    2   mainly in Bermuda."   Tr. at 1832 (June 23, 2009).
    3             The umpire, Dassenko, made further disclosures on March
    4   28, 2009; June 24, 2009; and July 1, 2009.   For example, Dassenko
    5   explained that his private equity firm had been retained to
    6   assist with the run-off of an insurer that had a potential
    7   dispute with St. Paul's parent company, and that he had prior
    8   business contacts with a St. Paul underwriter whose name had been
    9   mentioned during the evidentiary hearing.
    10             The Arbitral Award
    11             The arbitration proceedings addressed the question
    12   whether the parties had agreed to limit Scandinavian's total
    13   financial exposure under the Agreement.    St. Paul argued that the
    14   Agreement was valid and that its express terms -- which contained
    15   no explicit limit -- should be enforced.    Scandinavian sought
    16   rescission of the Agreement on the grounds of misrepresentation,
    17   or in the alternative, for rescission or reformation based on
    18   unilateral or mutual mistake.
    19             During the final evidentiary hearing, held between June
    20   15, 2009, and July 1, 2009, fourteen witnesses testified.    Among
    21   them was Bart Hedges, who then served as president and CEO of
    22   Scandinavian and who had been an employee of Scandinavian at the
    23   time the Agreement was executed.
    11
    1             The arbitral panel issued their award (the "Award") on
    2   August 19, 2009.   A majority of the panel10 concluded that the
    3   Agreement was valid and should be enforced according to its
    4   terms, thereby exposing Scandinavian to an aggregate limit of
    5   approximately $290 million in liability.   With respect to several
    6   other matters, including the question of whether the Agreement
    7   had created one experience account or three, the panel ruled
    8   unanimously in favor of St. Paul.
    9             The Platinum Arbitration and its Non-Disclosure
    10             While proceedings in the St. Paul Arbitration were
    11   ongoing, another reinsurance arbitration -- the Platinum
    12   Arbitration -- began.   It involved a reinsurance dispute between
    13   PMA Capital Insurance Company and several of its affiliates
    14   (collectively, "PMA") and Platinum Underwriters Bermuda, Ltd.
    15   ("Platinum").   Platinum was PMA's re-insurer.   In June 2008 --
    16   about three months after the organizational meeting was held in
    17   the St. Paul Arbitration -- Platinum demanded arbitration against
    18   PMA in order to interpret a reinsurance contract between those
    19   two parties.
    20             Two of the arbitrators from the St. Paul Arbitration --
    21   Gentile, St. Paul's party-appointed arbitrator, and Dassenko, the
    22   umpire -- were subsequently selected to serve on the panel in the
    10
    Scandinavian asserts, and St. Paul does not dispute, that
    this majority included Gentile and Dassenko but not Rosen.
    Although the Award itself does not indicate which arbitrators
    joined in the holding, we, like the district court, see
    Scandinavian, 732 F. Supp. 2d at 299 n.43, have no reason not to
    accept that Dassenko and Gentile were in the majority.
    12
    1   Platinum Arbitration.   Platinum selected Gentile as its party-
    2   appointed arbitrator, and Dassenko, there too, was chosen to
    3   serve as umpire.   Those appointments occurred sometime between
    4   early June and late September, 2008.   The organizational meeting
    5   for the Platinum Arbitration was held on September 23, 2008.   The
    6   evidentiary hearing was held in three one-day sessions in March
    7   through May, 2009.   The Platinum Arbitration ended with the
    8   issuance of an award on May 22, 2009, about four weeks before the
    9   start of the evidentiary hearing in the St. Paul Arbitration.11
    10   The Platinum Arbitration was therefore concurrent with the St.
    11   Paul Arbitration, as the St. Paul Arbitration began prior to, and
    12   ended after, the Platinum Arbitration.
    13             Despite the many disclosures made by Dassenko and
    14   Gentile during the St. Paul Arbitration -- including disclosures
    15   about the specific matter of their participation in other
    16   arbitrations involving the same arbitrators -- it is undisputed
    17   that neither Dassenko nor Gentile ever disclosed to the parties
    18   the fact of their concurrent service in the Platinum Arbitration.
    19   See Scandinavian, 732 F. Supp. 2d at 298.   And although Dassenko
    11
    Following the award in the Platinum Arbitration, PMA
    filed a petition to vacate that award in the United States
    District Court for the Eastern District of Pennsylvania. The
    district court granted the petition on the grounds that the award
    was "completely irrational," insofar as the award purported to
    strike out part of the parties' contract without any authority
    for doing so. PMA Capital Ins. Co. v. Platinum Underwriters
    Bermuda, Ltd., 
    659 F. Supp. 2d 631
    , 636-39 (E.D. Pa. 2009). The
    district court's decision to vacate the award was upheld on
    appeal. See PMA Capital Ins. Co. v. Platinum Underwriters
    Bermuda, Ltd., 
    400 F. App'x 654
     (3d Cir. 2010).
    13
    1   and Gentile each disclosed to Platinum and PMA that they were
    2   then serving together as arbitrators in another matter -- the
    3   arbitration at issue here -- neither of them specifically
    4   identified St. Paul or Scandinavian as the parties involved in
    5   it.12        
    Id. at 300
    .
    6                   Similarities Between the Platinum
    7                   Arbitration and the St. Paul Arbitration
    8                   As described by the district court, the Platinum
    9   Arbitration appeared to resemble the St. Paul Arbitration in
    10   several ways.
    11                   First, as noted above, Gentile served as the party-
    12   appointed arbitrator for the claimant in both proceedings, and
    13   Dassenko presided as umpire over each panel.        See 
    id. at 300
    .
    14                   Second, although St. Paul was not itself a party to the
    15   Platinum Arbitration, St. Paul's business was related in several
    16   ways to Platinum's.        See 
    id. at 301-02
    .   Most importantly, after
    17   St. Paul contributed its rights to renew its existing reinsurance
    18   contracts to Platinum's parent in 2002, Platinum succeeded St.
    19   Paul as PMA's reinsurer.       Moreover, the core of Platinum's claim
    20   in the Platinum Arbitration was that, in calculating the balance
    21   of the "experience account" created by the Platinum-PMA contract,
    22   Platinum was entitled to carry forward certain losses that had
    23   been incurred by St. Paul under St. Paul's previous reinsurance
    12
    To the contrary, Gentile represented -- incorrectly -- to
    Platinum and PMA that the Platinum Arbitration was the first
    matter that he would serve on that would involve St. Paul in any
    way.
    14
    1   contract with PMA.13   See 
    id. at 299
    ; PMA Capital Ins. 
    659 F. 2
       Supp. 2d at 639 (noting that the interpretation of the contract's
    3   "Deficit Carry Forward Provision" was the "gravamen" of the
    4   parties' dispute in the Platinum Arbitration).   St. Paul asserts,
    5   however, that the district court mischaracterized the facts and
    6   that Platinum is not "truly related" to it in any meaningful way.
    7   Appellants' Br. at 49.
    8             Third, Hedges -- a past employee of both Scandinavian
    9   and Platinum -- testified in both proceedings. See Scandinavian,
    10   732 F. Supp. 2d at 306-07 & nn.112, 113.   Hedges' testimony in
    11   each proceeding related to two distinct periods of past
    12   employment.   Nonetheless, the district court posited that
    13   Dassenko and Gentile could have concluded that Hedges testified
    14   inconsistently -- and therefore lacked credibility -- insofar as,
    15   in the Platinum Arbitration, Hedges testified in favor of
    16   "interpreting the Platinum[-PMA] Agreement as written," while in
    13
    The district court also took note of two other, more
    indirect, connections between St. Paul and Platinum.
    First, at the time of the Platinum Arbitration, a St. Paul
    affiliate known as "Travelers Special Services" was under
    contract with a Platinum affiliate to "administer claims and to
    provide actuarial and administrative services." Scandinavian,
    732 F. Supp. 2d at 302 (internal quotation marks omitted). This
    arrangement was not at issue in the Platinum Arbitration.
    Second, after the initial public offering of Platinum's
    parent holding company in 2002, some 180 employees left St. Paul
    for Platinum. Among them was one St. Paul employee who was
    centrally involved in negotiating the Agreement between St. Paul
    and Scandinavian, and who later served as a witness in the St.
    Paul Arbitration. Id.
    15
    1   the St. Paul Arbitration, Hedges testified in favor of
    2   "interpreting the Scandinavian[-St. Paul] Agreement in light of
    3   Scandinavian[]'s intent at the time it entered into the
    4   agreement."    Id. at 308 (emphasis in original).   St. Paul, for
    5   its part, argues that "the involvement of Hedges as a witness in
    6   the two unrelated arbitrations is . . . irrelevant."    Appellants'
    7   Br. at 51.
    8                Fourth, the district court determined that the two
    9   arbitrations "shared similar [legal] issues."    Id. at 307.
    10                [B]oth arbitrations required the arbitrators
    11                to (1) consider whether a finite[14]
    12                retrocessional agreement should be enforced
    13                according to the express terms of the
    14                agreement or whether the agreement should be
    15                interpreted in light of the parties'
    16                intentions at the formation of the agreement
    17                and (2) interpret contract language regarding
    18                the creation of experience accounts.
    19   Id. at 307 n.118.    Again, however, St. Paul criticizes the
    20   district court's assessment of similarity, arguing that it is
    21   couched at an "overly broad" level of generality.    Appellants'
    22   Br. at 50.
    23                The District Court Proceedings
    14
    On appeal, Scandinavian persists in describing the
    Agreement as "finite," see Appellee's Br. at 4, 11, 39, and the
    district court described the Agreement using the same term, see
    Scandinavian, 732 F. Supp. 2d at 295, 307 n.118. It appears,
    however, that finiteness -- i.e., whether the "the amount of risk
    transferred from St. Paul to Scandinavian [] was limited," id. at
    295 -- was the very matter that was disputed in the St. Paul
    Arbitration and which was ultimately resolved favorably to St.
    Paul.
    16
    1             Scandinavian represents that it first became aware that
    2   Dassenko and Gentile had served together on the Platinum
    3   Arbitration two months after the Award was issued.15   On November
    4   16, 2009, Scandinavian filed a petition to vacate the Award in
    5   the United States District Court for the Southern District of New
    6   York pursuant to the FAA on grounds of evident partiality.    See 9
    
    7 U.S.C. § 10
    (a)(2).   Scandinavian asserted that the fact that
    8   Dassenko and Gentile had failed to disclose their concurrent
    9   service in the Platinum Arbitration -- a proceeding that,
    10   Scandinavian contended, involved "a common witness, similar
    11   disputed issues and contract terms, and the company that
    12   succeeded to the business of St. Paul," Am. Pet. to Vacate
    13   Arbitration Award at 2 (Dec. 21, 2009), at J.A. 202 -- reflected
    14   bias by those arbitrators in St. Paul's favor.
    15             On December 30, 2009, St. Paul opposed Scandinavian's
    16   petition and filed a cross-petition to confirm the arbitration
    17   award under 
    9 U.S.C. § 9
    .   St. Paul did not dispute that Dassenko
    18   and Gentile had failed to disclose their concurrent service in
    19   the Platinum Arbitration, arguing instead that there was no basis
    20   upon which to conclude that nondisclosure was indicative of bias.
    21             On February 23, 2010, the district court granted
    22   Scandinavian's petition and denied St. Paul's cross-petition,
    23   concluding that the arbitrators' failure to disclose their
    15
    Scandinavian represents that it learned of the concurrent
    service after its counsel discovered the district court's
    decision vacating the award in the Platinum Arbitration.
    17
    1   concurrent service in the Platinum Arbitration constituted
    2   evident partiality.   See Scandinavian, 732 F. Supp. 2d at 307-09.
    3   The court observed that the two arbitrations "were presided over
    4   by two common arbitrators, overlapped in time, shared similar
    5   issues, involved related parties, [and] included Hedges as a
    6   common witness."    Id. at 307-08 (footnotes omitted).   The court
    7   further reasoned:
    8             By participating in both the [St. Paul]
    9             Arbitration and the Platinum[] Arbitration,
    10             Dassenko and Gentile placed themselves in a
    11             position where they could receive ex parte
    12             information about the kind of reinsurance
    13             business at issue in the [St. Paul]
    14             Arbitration, be influenced by recent
    15             credibility determinations they made as a
    16             result of Hedges's testimony in the
    17             Platinum[] Arbitration, and influence each
    18             other's thinking on issues relevant to the
    19             [St. Paul] Arbitration. By failing to
    20             disclose their participation in the
    21             Platinum[] [A]rbitration, Dassenko and
    22             Gentile deprived Scandinavian[] of an
    23             opportunity to object to their service on
    24             both arbitration panels and/or adjust their
    25             arbitration strategy.
    26   Id. at 308 (footnote omitted).
    27             The court also contrasted Dassenko's and Gentile's
    28   failure to disclose their concurrent service in the Platinum
    29   Arbitration with the many "other less significant or temporally
    30   remote relationships that Dassenko and Gentile considered
    31   important enough to disclose," id. at 308-09, and suggested that
    32   that comparison "strengthened" the court's conclusion that
    33   Dassenko and Gentile should have informed the parties of their
    34   simultaneous service, id.
    18
    1              The district court concluded that "[t]aken together,
    2   these factors indicate that Dassenko and Gentile's simultaneous
    3   service as arbitrators" in the two proceedings "constituted a
    4   material conflict of interest."     Id. at 308.     And because that
    5   conflict had not been disclosed, the court decided, the
    6   nondisclosure met this Circuit's test for evident partiality.
    7   Id. at 309 (citing Applied Industrial, 
    492 F.3d at 138
    ).          The
    8   court vacated the Award and remanded the matter for arbitration
    9   before a new arbitral panel.     
    Id.
    10              St. Paul appeals.
    11                                  DISCUSSION
    12              I.   Review Of Arbitral Awards
    13   A.   Applicability of the New York Convention
    14              The FAA does not "independently confer subject matter
    15   jurisdiction on the federal courts."        Durant, Nichols, Houston,
    16   Hodgson & Cortese-Costa, P.C. v. Dupont, 
    565 F.3d 56
    , 63 (2d Cir.
    17   2009).   "[T]here must be an independent basis of jurisdiction
    18   before a district court may entertain petitions" to confirm or
    19   vacate an award under the FAA.     
    Id.
     (internal quotation marks).
    20   In this case, the district court had subject-matter jurisdiction
    21   under 
    9 U.S.C. § 203
    , which provides federal jurisdiction over
    22   actions to confirm or vacate an arbitral award that is governed
    23   by the Convention on the Recognition and Enforcement of Foreign
    24   Arbitral Awards (the "New York Convention").       The New York
    19
    1   Convention applies in this case because Scandinavian is a foreign
    2   corporation.   See 
    9 U.S.C. § 202
    .
    3              Because the Award in the St. Paul Arbitration was
    4   entered in the United States, however, the domestic provisions of
    5   the FAA also apply, as is permitted by Articles V(1)(e) and V(2)
    6   of the New York Convention.    See Zeiler v. Deitsch, 
    500 F.3d 157
    ,
    7   164 (2d Cir. 2007) (describing overlap of New York Convention and
    8   the FAA); Yusuf Ahmed Alghanim & Sons, W.L.L. v. Toys "R" Us,
    9   Inc., 
    126 F.3d 15
    , 19-23 (2d Cir. 1997), cert. denied, 
    522 U.S. 10
       1111 (1998).   "[T]he FAA and the New York Convention work in
    11   tandem, and they have overlapping coverage to the extent that
    12   they do not conflict."   Sole Resort, S.A. de C.V. v. Allure
    13   Resorts Mgmt., LLC, 
    450 F.3d 100
    , 102 n.1 (2d Cir. 2006)
    14   (internal quotation marks omitted).     Neither party disputes that
    15   section 10 of the FAA governs the issues before us on this
    16   appeal.   See 
    9 U.S.C. § 10
    .
    17   B.   Standards of Review
    18              "When reviewing a district court's decision to vacate
    19   an arbitration award, we review findings of fact for clear error
    20   and questions of law de novo."16     Applied Industrial, 
    492 F.3d at
    21   136; see also Zeiler, 
    500 F.3d at 164
    .
    16
    The parties dispute whether the appropriate standard of
    review for conclusions regarding mixed questions of law and fact
    is de novo or clear error in the context of petitions to vacate
    arbitration awards. Because we conclude that the result below
    rests on legal error, we need not reach this question.
    20
    1              A court reviewing an arbitration award under the FAA
    2   "can confirm and/or vacate the award, either in whole or in
    3   part."   D.H. Blair & Co. v. Gottdiener, 
    462 F.3d 95
    , 104 (2d Cir.
    4   2006).   But a petition brought under the FAA is "not an occasion
    5   for de novo review of an arbitral award."    Wallace v. Buttar, 378
    
    6 F.3d 182
    , 189 (2d Cir. 2004).    A court's review of an arbitration
    7   award is instead "severely limited," ReliaStar Life Ins. Co. of
    8   N.Y. v. EMC Nat. Life Co., 
    564 F.3d 81
    , 85 (2d Cir. 2009), so as
    9   not to frustrate the "twin goals of arbitration, namely, settling
    10   disputes efficiently and avoiding long and expensive litigation,"
    11   Rich v. Spartis, 
    516 F.3d 75
    , 81 (2d Cir. 2008) (internal
    12   quotation mark omitted).    "This Court has repeatedly recognized
    13   the strong deference appropriately due arbitral awards and the
    14   arbitral process, and has limited its review of arbitration
    15   awards in obeisance to that process."   Porzig v. Dresdner,
    16   Kleinwort, Benson, N. Am. LLC, 
    497 F.3d 133
    , 138 (2d Cir. 2007)
    17   (citation omitted).    Therefore, in order to obtain vacatur of the
    18   decision of an arbitral panel under the FAA, a party "must clear
    19   a high hurdle."    Stolt-Nielson S.A. v. AnimalFeeds Int'l Corp.,
    20   
    130 S. Ct. 1758
    , 1767 (2010); see also Wallace, 378 F.3d at 189
    21   (referring to the "heavy burden" on the party seeking vacatur
    22   under the FAA).
    23              II.    Evident Partiality
    24   A.   Governing Law
    25              The FAA provides that district courts may vacate an
    26   arbitral award "where there was evident partiality or corruption
    21
    1   in the arbitrators, or either of them."    
    9 U.S.C. § 10
    (a)(2).      In
    2   this Circuit, "evident partiality within the meaning of 9 U.S.C.
    3   § 10 will be found where a reasonable person would have to
    4   conclude that an arbitrator was partial to one party to the
    5   arbitration."    Morelite, 
    748 F.2d at 84
     (internal quotation marks
    6   omitted).    "Unlike a judge, who can be disqualified in any
    7   proceeding in which his impartiality might reasonably be
    8   questioned," Applied Industrial, 
    492 F.3d at 137
     (emphasis and
    9   internal quotation marks omitted), "an arbitrator is disqualified
    10   only when a reasonable person, considering all the circumstances,
    11   would have to conclude that an arbitrator was partial to one
    12   side," 
    id.
     (emphasis in original; internal quotation marks
    13   omitted).    Proof of actual bias is not required, however.    See
    14   United States v. Int'l Bhd. of Teamsters, 
    170 F.3d 136
    , 147 (2d
    15   Cir. 1999).    A conclusion of partiality can be inferred "from
    16   objective facts inconsistent with impartiality."    Pitta v. Hotel
    17   Ass'n of N.Y.C., Inc., 
    806 F.2d 419
    , 423 n.2 (2d Cir. 1986).         Of
    18   course, a showing of evident partiality "may not be based simply
    19   on speculation."    Int'l Bhd. of Teamsters, 
    170 F.3d at 147
    ; see
    20   also Three S Del., Inc. v. DataQuick Info. Sys., Inc., 
    492 F.3d 21
       520, 530 (4th Cir. 2007) (noting that the "asserted bias" may not
    22   be "remote, uncertain or speculative" (internal quotation marks
    23   omitted)).
    24                The burden of proving evident partiality "rests upon
    25   the party asserting bias."    Andros Compania Maritima, S.A. v.
    26   Marc Rich & Co., A.G., 
    579 F.2d 691
    , 700 (2d Cir. 1978) (internal
    22

    8             Among the circumstances under which the evident-
    9   partiality standard is likely to be met are those in which an
    10   arbitrator fails to disclose a relationship or interest that is
    11   strongly suggestive of bias in favor of one of the parties. See,
    12   e.g., Applied Industrial,

    19   "too insubstantial to warrant vacating the award."

    2   considered the standard for obtaining vacatur based upon
    3   nondisclosure.   There, we reaffirmed the principle that where
    4   "[a]n arbitrator . . . knows of a material relationship with a
    5   party" but fails to disclose it, "[a] reasonable person would
    6   have to conclude that [the] arbitrator who failed to disclose
    7   under such circumstances was partial to one side."   Applied
    8   Industrial, 
    492 F.3d at 137

     (recognizing same principle).17
    10   B.   Analysis
    11             The district court in the case before us concluded that
    12   Dassenko's and Gentile's simultaneous service in the Platinum
    17
    In Applied Industrial we observed that, up to that time
    (July 2007) we had not considered whether arbitrators possess a
    "duty to investigate or disclose potential conflicts of
    interest," that is, conflicts about which an arbitrator does not
    yet possess "actual knowledge." 
    Id. at 138
    . Turning to that
    question, and relying upon Justice White's concurring opinion in
    Commonwealth Coatings Corp. v. Continental Cas. Co., 
    393 U.S. 145
    (1968), we reasoned that "arbitrators must take steps to ensure
    that the parties are not misled into believing that no nontrivial
    conflict exists." Applied Industrial, 
    492 F.3d at 138
    .
    Accordingly, we articulated a prophylactic rule applicable in
    circumstances in which an arbitrator thinks a nontrivial conflict
    may exist, but is not sure:
    [W]here an arbitrator has reason to believe
    that a nontrivial conflict of interest might
    exist, he must (1) investigate the conflict
    (which may reveal information that must be
    disclosed under Commonwealth Coatings) or (2)
    disclose his reasons for believing there
    might be a conflict and his intention not to
    investigate.
    
    Id.
     We concluded that if an arbitrator fails to follow this rule
    by investigating or disclosing a potential nontrivial conflict of
    interest, such a failure "is indicative of evident partiality."
    
    Id.
    24
    1   Arbitration constituted a "material conflict of interest"
    2   requiring disclosure to the parties.     Scandinavian, 
    732 F. Supp. 3
       2d at 308.    Relying upon our decisions in Morelite and Applied
    4   Industrial, the court then decided that Dassenko and Gentile's
    5   failure to disclose that simultaneous service warranted vacatur
    6   on evident-partiality grounds.    We disagree.
    7                The evident-partiality standard is, at its core,
    8   directed to the question of bias.      Because it was "[not] the
    9   purpose of Congress to authorize litigants to submit their cases
    10   and controversies" to arbitrators who are "biased against one
    11   litigant and favorable to another," Commonwealth Coatings, 393
    12   U.S. at 150 (Black, J.) (plurality opinion), the FAA provides for
    13   vacatur of arbitral awards whenever it is "evident" that an
    14   arbitrator was "partial[]" to one of the litigating parties.       9
    
    15 U.S.C. § 10
    (a)(2).    It follows that where an undisclosed matter
    16   is not suggestive of bias, vacatur based upon that nondisclosure
    17   cannot be warranted under an evident-partiality theory.     See,
    18   e.g., STMicroelecs., N.V. v. Credit Suisse Sec. (USA) LLC, 648
    
    19 F.3d 68
    , 74 (2d Cir. 2011) (recognizing in dicta that the
    20   "evident partiality" decisions address only "facts bearing on
    21   partiality") (emphasis in original); Lagstein v. Certain
    22   Underwriter's at Lloyd's, London, 
    607 F.3d 634
    , 646 (9th Cir.
    23   2010) (emphasizing that an arbitrator is "required to disclose
    24   only facts indicating that he might reasonably be thought biased
    25   against one litigant and favorable to another") (emphasis in
    26   original; internal quotation marks omitted).
    25
    1             Several courts have identified a variety of factors for
    2   use in guiding a district court in the application of the
    3   evident-partiality test in cases where a party seeks vacatur of
    4   an arbitration award because of an arbitrator's nondisclosure. We
    5   find those adopted by the Fourth Circuit helpful:
    6             To determine if a party has established
    7             [evident] partiality, a court should assess
    8             four factors: "(1) the extent and character
    9             of the personal interest, pecuniary or
    10             otherwise, of the arbitrator in the
    11             proceedings; (2) the directness of the
    12             relationship between the arbitrator and the
    13             party he is alleged to favor; (3) the
    14             connection of that relationship to the
    15             arbitrator; and (4) the proximity in time
    16             between the relationship and the arbitration
    17             proceeding."

    492 F.3d at 530
     (quoting ANR Coal Co. v.
    19   Cogentrix of N.C., Inc., 
    173 F.3d 493
    , 500 (4th Cir. 1999), cert.
    20   denied, 
    528 U.S. 877
     (1999)).   While those factors are useful, we
    21   do not view them as mandatory, exclusive or dispositive.18
    18
    Several district courts in this Circuit have employed
    similar factors that may be considered in undertaking the
    Morelite analysis. See, e.g., Toroyan v. Barrett, 
    495 F. Supp. 2d 346
    , 352 (S.D.N.Y. 2007) (considering "(1) the financial
    interest the arbitrator has in the proceeding; (2) the directness
    of the alleged relationship between the arbitrator and a party to
    the arbitration; (3) and the timing of the relationship with
    respect to the arbitration proceeding" (internal quotation marks
    omitted)); In re Arbitration between Carina Int'l Shipping Corp.
    & Adam Mar. Corp., 
    961 F. Supp. 559
    , 568 (S.D.N.Y. 1997)
    (considering "(1) peculiar commercial practices in the geographic
    area; (2) an arbitrator's financial interest in the arbitration;
    (3) the nature of the relationship between the arbitrator and the
    alleged favored party; and (4) whether the relationship existed
    during the arbitration").
    26
    1             We conclude that Scandinavian has not met its burden of
    2   establishing that Dassenko and Gentile's service in the Platinum
    3   Arbitration was indicative of bias in these proceedings so as to
    4   constitute a nontrivial conflict of interest.19 Therefore, the
    5   arbitrators' failure to disclose their concurrent service does
    6   not require vacatur.
    7             First, as a general matter, we do not think that the
    8   fact that two arbitrators served together in one arbitration at
    9   the same time that they served together in another is, without
    10   more, evidence that they were predisposed to favor one party over
    11   another in either arbitration.   The undisclosed matter here was
    12   overlapping arbitral service, not a "material relationship with a
    13   party," Applied Industrial, 
    492 F.3d at 137
    , such as a family
    14   connection or ongoing business arrangement with a party or its
    15   law firm -- circumstances in which a reasonable person could
    16   reasonably infer a connection between the undisclosed outside
    17   relationship and the possibility of bias for or against a
    18   particular arbitrating party.    We agree with St. Paul that "the
    19   mere fact of [such] overlapping arbitral service suggests nothing
    20   inherently negative about the impartiality of the arbitrators."20
    19
    Because Dassenko and Gentile had actual knowledge of the
    facts surrounding their participation in the Platinum
    Arbitration, we need only consider whether these facts were
    sufficiently suggestive of bias. We need not address any
    potential duty to investigate.
    20
    Such overlapping service is not only not a circumstance
    inherently indicative of bias; it is also not unusual. In
    specialized fields such as reinsurance, where there are a limited
    27
    1   Appellants' Reply Br. at 19.    And despite the overlap, there is
    2   no indication here that either of the arbitrators was predisposed
    3   to rule any particular way in the Scandinavian Arbitration as a
    4   result of the Platinum Arbitration.
    5             Scandinavian, in arguing to the contrary, appears to
    6   ask us to infer partiality from the arbitrators' overlapping
    7   service because the Award in the St. Paul Arbitration was
    8   rendered in St. Paul's favor.   But the fact that one party loses
    9   at arbitration does not, without more, tend to prove that an
    10   arbitrator's failure to disclose some perhaps disclosable
    11   information should be interpreted as showing bias against the
    12   losing party.   We have repeatedly said that adverse rulings alone
    13   rarely evidence partiality, whether those adverse rulings are
    14   made by arbitrators, see, e.g., Thomas C. Baer, Inc. v.
    15   Architectural & Ornamental Iron Workers Local Union No. 580, 813
    
    16 F.2d 562
    , 565 (2d Cir. 1987), or by judges, see, e.g., Chen v.
    17   Chen Qualified Settlement Fund, 
    552 F.3d 218
    , 227 (2d Cir. 2009)
    number of experienced arbitrators, it is common for the same
    arbitrators to end up serving together frequently. See, e.g.,
    Dow Corning Corp. v. Safety Nat'l Cas. Corp., 
    335 F.3d 742
    , 750
    (8th Cir. 2003) ("[T]he relatively small number of qualified
    arbitrators may make it common, if not inevitable, that parties
    will nominate the same arbitrators repeatedly."), cert. denied,

    arbitrators available to sit on insurance arbitration disputes is
    quite small and . . . arbitrators often sit together on a number
    of disputes."), aff'd,

     (2d Cir. 1988).
    28
    1   (per curiam) (citing Liteky v. United States, 
    510 U.S. 540
    , 555
    2   (1994)).
    3              Nor do we consider any of the identified similarities
    4   between the St. Paul Arbitration and the Platinum Arbitration to
    5   suggest bias.    The district court was correct in observing that
    6   the same witness, Hedges, testified in both proceedings; that the
    7   interpretation of stop-loss reinsurance agreements containing
    8   "experience account" features was at issue in both; and that past
    9   and ongoing business relationships existed between Platinum and
    10   its affiliates and St. Paul and its affiliates.    See
    11   Scandinavian, 732 F. Supp. 2d at 307-08.     But the fact that one
    12   arbitration resembles another in some respects does not suggest
    13   to us that an arbitrator presiding in both is somehow therefore
    14   likely to be biased in favor of or against any party.    Cf.
    15   Liteky, 
    510 U.S. at 561-62
     (Kennedy, J., concurring) (observing
    16   that the fact that same judge presides over related cases
    17   ordinarily does not suggest that judge is biased).
    18              To be sure, as Scandinavian points out, material
    19   conflicts of interest need not be direct relationships between
    20   arbitrators and parties to the arbitration.    As the district
    21   court put it, "[a] reasonable person concludes that an arbitrator
    22   is partial to one side because the undisclosed relationship is
    23   material, not because the material relationship is with a party."
    24   Id. at 306.     But, in ascertaining whether a relationship is
    25   "material" -- or, to use the terminology of Applied Industrial,
    26   whether it is "nontrivial" -- we think that a court must focus on
    29
    1   the question of how strongly that relationship tends to indicate
    2   the possibility of bias in favor of or against one party, and not
    3   on how closely that relationship appears to relate to the facts
    4   of the arbitration.   See Morelite, 
    748 F.2d at 84
     ("[E]vident
    5   partiality . . . will be found where a reasonable person would
    6   have to conclude that an arbitrator was partial to one party to
    7   the arbitration." (internal quotation marks omitted)).     In other
    8   words, even if a particular relationship might be thought to be
    9   relevant "to the arbitration at issue," Scandinavian, 
    732 F. 10
       Supp. 2d at 307, that relationship will nevertheless not
    11   constitute a material conflict of interest if it does not itself
    12   tend to show that the arbitrator might be predisposed in favor of
    13   one (or more) of the parties.   As we put it in Applied
    14   Industrial, for a relationship to be material, and therefore
    15   require disclosure, it must be such that "[a] reasonable person
    16   would have to conclude that an arbitrator who failed to disclose
    17   [it] . . . was partial to one side."   Applied Industrial, 492
    18   F.3d at 137.
    19             We understand, of course, that Gentile was a party-
    20   appointed arbitrator in each arbitration, and that he represented
    21   the respective claimants (St. Paul and Platinum) in each.21    We
    21
    Before the district court, St. Paul argued in passing that
    Scandinavian should bear a higher burden for proving partiality
    as to Gentile than as to Dassenko because Gentile is a party-
    appointed arbitrator. Several courts have observed that, in
    tripartite arbitrations such as this one, parties often expect
    the party-appointed arbitrators to serve as informal advocates
    for their respective parties in deliberating with the neutral
    third arbitrator. See, e.g., Sphere Drake, 
    307 F.3d at 620
     (7th
    30
    1   also acknowledge the district court's factual findings that
    2   Platinum and its affiliates and St. Paul and its affiliates had
    3   various past and ongoing business relationships.   See
    4   Scandinavian, 732 F. Supp. 2d at 301-02.   But there is no
    5   indication in the record that Gentile was appointed by Platinum
    6   at the recommendation of St. Paul, or that Gentile or Dassenko
    7   had any special financial or professional interest in ruling in
    8   St. Paul's favor as a result of their participation in the
    9   Platinum Arbitration.
    10             Scandinavian asserts that vacatur is nonetheless
    11   warranted because it was misled by Dassenko's and Gentile's
    12   repeated assurances to the parties that they understood
    13   themselves obligated to make thorough and ongoing disclosures.
    14   In light of those assurances and the many opportunities during
    Cir. 2002), cert. denied, 
    538 U.S. 961
     (2003); Lozano v. Md. Cas.

    see Florasynth, Inc. v. Pickholz, 
    750 F.2d 171
    , 173 (2d Cir.
    1984) (suggesting that party-appointed arbitrators are "not to
    act merely as partisan advocates"). And for that reason, several
    of our sister circuits have concluded that the FAA imposes a
    heightened bar to, or altogether forecloses, an evident-
    partiality challenge premised solely on the alleged bias of a
    party-appointed arbitrator in favor of the party who appointed
    him. See, e.g., Winfrey v. Simmons Foods, Inc., 
    495 F.3d 549
    ,
    551-52 (8th Cir. 2007); Nationwide Mut. Ins. Co. v. Home Ins.
    Co., 
    429 F.3d 640
    , 645-47 & n.8 (6th Cir. 2005); Sphere Drake
    Ins. Ltd., 
    307 F.3d at 623
    . However, because St. Paul has not
    pressed that argument on appeal -- and because we conclude that
    Scandinavian's evident-partiality challenge fails in any event --
    we need not decide at this time whether the FAA imposes a
    heightened burden of proving evident partiality in cases in which
    the allegedly biased arbitrator was party-appointed.
    31
    1   the St. Paul Arbitration when the arbitrators' concurrent service
    2   in the Platinum Arbitration might have come to mind, Scandinavian
    3   argues, "[b]oth arbitrators simply could not have continually
    4   failed to see what was right in front of their eyes for so long."
    5   Appellee's Br. at 48.   The district court, apparently crediting
    6   this argument, indicated that in ordering vacatur it relied on
    7   the fact that Dassenko and Gentile had informed the parties of
    8   many other "less significant or temporally remote relationships."
    9   Scandinavian, 732 F. Supp. 2d at 308-09.
    10             We conclude that vacatur was not called for.   In the
    11   first place, we do not think it appropriate to vacate an award
    12   solely because an arbitrator fails to consistently live up to his
    13   or her announced standards for disclosure, or to conform in every
    14   instance to the parties' respective expectations regarding
    15   disclosure.22   The nondisclosure does not by itself constitute
    16   evident partiality.   The question is whether the facts that were
    22
    Even where an arbitrator fails to abide by arbitral or
    ethical rules concerning disclosure, such a failure does not, in
    itself, entitle a losing party to vacatur. See, e.g., Positive
    Software Solutions, Inc. v. New Century Mortg. Corp., 
    476 F.3d 278
    , 285 n.5 (5th Cir. 2007); Montez v. Prudential Sec., Inc.,
    
    260 F.3d 980
    , 984 (8th Cir. 2001); ANR Coal Co., 
    173 F.3d at 499
    ;
    Merit Ins. Co. v. Leatherby Ins. Co., 
    714 F.2d 673
    , 680-81 (7th
    Cir. 1983), cert. denied, 
    464 U.S. 1009
     (1983). But see
    Commonwealth Coatings, 393 U.S. at 149 (Black, J.) (plurality
    opinion) (describing the AAA disclosure guidelines as "highly
    significant" to the evident partiality analysis); New Regency
    Prods., Inc. v. Nippon Herald Films, Inc., 
    501 F.3d 1101
    , 1109-10
    (9th Cir. 2007) (relying on ethical and arbitral rules as
    persuasive authority). This is not a case in which the parties
    have specified a standard for arbitrator impartiality.
    Accordingly, we need not decide whether noncompliance with such
    an agreed-upon standard would require a finding of "evident
    partiality."
    32
    1   not disclosed suggest a material conflict of interest.   An
    2   approach that examined why an arbitrator failed to disclose a
    3   relationship would interject added uncertainty and subjectivity
    4   into our evident-partiality analysis.   See Int'l Bhd. of
    5   Teamsters, 
    170 F.3d at 146
     (describing the test for evident
    6   partiality as being "whether an objective, disinterested
    7   observer" would conclude that the arbitrator was biased (emphasis
    8   added)).   Such an approach might, moreover, have perverse effects
    9   because if it were the rule that vacatur would be warranted for
    10   an arbitrator's failure to live up to his or her own particularly
    11   punctilious standards of disclosure, arbitrators would have less
    12   of an incentive to set a high standard for their disclosures in
    13   the first place.
    14              Secondly, we reject Scandinavian's assertion that the
    15   nondisclosure can only be explained by bias in favor of St. Paul.
    16   The record does not indicate why the information was not
    17   disclosed, but we do not find it implausible that Dassenko and
    18   Gentile labored under the false impression that they had made a
    19   disclosure which in fact they had failed to make, particularly in
    20   light of the fact that they did disclose (although not by name)
    21   the existence of the Scandinavian arbitration in the PMA
    22   proceeding.   St. Paul suggests that the nondisclosure may have
    23   occurred because of "sheer inadvertence, a mistaken belief that
    24   they had already disclosed it, or non-materiality."   Appellants'
    25   Reply Br. at 18.   Indeed, Peter Gentile seems to have operated
    26   under just such a false impression with respect to another matter
    33
    1   which he failed to disclose until late in the arbitration.    In
    2   any event, the arbitrators' conduct is not such that a
    3   "reasonable person would have to conclude that an arbitrator was
    4   partial" to St. Paul. Morelite, 
    748 F.2d at 84
     (emphasis added).
    5             We also reject Scandinavian's argument that vacatur is
    6   required because the presentation of its arbitration case was
    7   disadvantaged by Dassenko's and Gentile's nondisclosure.   See,
    8   e.g., Appellee's Br. at 44 ("If Scandinavian had known that
    9   Dassenko and Gentile had recently heard Hedges defend a contrary
    10   [position] in the other arbitration, it could have prepared for
    11   and presented Hedges' testimony in the [St. Paul] [A]rbitration
    12   differently, or not called him as a witness at all."); see also
    13   Scandinavian, 732 F. Supp. 2d at 308 & n.122 (concluding that the
    14   nondisclosure "deprived Scandinavian[] of an opportunity to . . .
    15   adjust [its] arbitration strategy," id. at 308).   The FAA does
    16   not bestow on a party the right to receive information about
    17   every matter that it might consider important or useful in
    18   presenting its case.   A party is not entitled to the "'complete
    19   and unexpurgated business biograph[ies]'" of the arbitrators whom
    20   the parties have selected.   Applied Industrial, 
    492 F.3d at
    139
    21   (quoting Commonwealth Coatings, 393 U.S. at 151 (White, J.,
    22   concurring)).
    23             Finally, we are not persuaded that other reasons given
    24   by the district court for vacating the award require us to
    25   conclude that the arbitrators were "evident[ly] partial[]."    The
    26   district court noted, Dassenko and Gentile "could [have]
    34
    1   receive[d] ex parte information" in the Platinum Arbitration
    2   about matters at issue in the St. Paul Arbitration, Scandinavian,
    3   732 F. Supp. 2d at 308; and might have been influenced by the
    4   "credibility determinations" they made about Hedges, id.; and
    5   could have "influence[d] each other's thinking on issues relevant
    6   to the [St. Paul] Arbitration," id.     But these possibilities do
    7   not establish bias.   See Trustmark Ins. Co. v. John Hancock Life
    8   Ins. Co. (U.S.A.), 
    631 F.3d 869
    , 873 (7th Cir. 2011) (arbitrators
    9   not disqualified merely because they acquired relevant knowledge
    10   in a previous arbitration), cert. denied, 
    131 S. Ct. 2465
     (2011);
    11   Int'l Bhd. of Teamsters, 
    170 F.3d at 147
     (evident partiality "may
    12   not be based simply on speculation").    Neither do they
    13   distinguish this case from any number of others successfully
    14   presided over by arbitrators -- or by judges for that matter.
    15             To be sure, in this case -- unlike in Applied
    16   Industrial -- Dassenko and Gentile plainly "had actual knowledge"
    17   of their concurrent service in the Platinum Arbitration.
    18   Scandinavian, 732 F. Supp. 2d at 309.    Although it would have
    19   been far better for them to have disclosed that fact, we do not
    20   think disclosure was required to avoid a vacatur of the Award in
    21   light of the fact that the relationship did not significantly
    22   tend to establish partiality.
    23             We do not in any way wish to demean the importance of
    24   timely and full disclosure by arbitrators.    Disclosure not only
    25   enhances the actual and apparent fairness of the arbitral
    26   process, but it helps to ensure that that process will be final,
    35
    1   rather than extended by proceedings like this one.       We again
    2   reiterate Justice White's observation that it is far better for a
    3   potential conflict of interest "[to] be disclosed at the outset"
    4   than for it to "come to light after the arbitration, when a
    5   suspicious or disgruntled party can seize on it as a pretext for
    6   invalidating the award."    Commonwealth Coatings, 393 U.S. at 151
    7   (White, J., concurring); accord Applied Industrial, 
    492 F.3d at
    8   139; Lucent Techs., 
    379 F.3d at 29
    ; Andros Compania Maritima, 579
    9   F.2d at 700.   But the better course is not necessarily the only
    10   permissible one.
    11             Because we agree with St. Paul that the district court
    12   erred in vacating the Award in this case, we need not consider
    13   its alternative argument on appeal that the district court should
    14   not have vacated the arbitrators' interim rulings.
    15             III.     Confirmation of the Award
    16             Under section 9 of the FAA, "a court 'must' confirm an
    17   arbitration award 'unless' it is vacated, modified or corrected
    18   'as prescribed' in §§ 10 and 11."      Hall St. Assocs., L.L.C. v.
    19   Mattel, Inc., 
    552 U.S. 576
    , 582 (2008).        And for petitions
    20   brought under the New York Convention, "[t]he court shall confirm
    21   the award unless it finds one of the grounds for refusal or
    22   deferral of recognition or enforcement of the award specified in
    23   the said Convention."    
    9 U.S.C. § 207
    ; see also Telenor Mobile
    24   Commc'ns AS v. Storm LLC, 
    584 F.3d 396
    , 405 (2d Cir. 2009) (same,
    25   citing section 207).
    36
    1             Scandinavian has identified no basis other than the
    2   asserted evident partiality for vacating the Award under the FAA
    3   or New York Convention.   Because we conclude that evident
    4   partiality was absent, St. Paul's cross-petition to confirm the
    5   Award must be granted.
    6                               CONCLUSION
    7             The judgment of the district court is reversed, and the
    8   case is remanded with instructions to the district court to deny
    9   Scandinavian's petition to vacate the Award, to grant St. Paul's
    10   cross-petition to confirm it, and to enter an amended judgment
    11   accordingly.
