    1. Jurisdiction: Appeal and Error. A jurisdictional question which does
    not involve a factual dispute is determined by an appellate court as a
    matter of law.
    2. Judgments: Arbitration and Award: Federal Acts: Appeal and
    Error. In reviewing a decision to vacate, modify, or confirm an arbi-
    tration award under the Federal Arbitration Act, an appellate court is

    obligated to reach a conclusion independent of the trial court’s ruling as
    to questions of law. However, the trial court’s factual findings will not
    be set aside on appeal unless clearly erroneous.
    3.   Attorney Fees: Appeal and Error. On appeal, a trial court’s decision
    awarding or denying attorney fees will be upheld absent an abuse of
    discretion.
    4.   ____: ____. When an attorney fee is authorized, the amount of the fee
    is addressed to the discretion of the trial court, whose ruling will not be
    disturbed on appeal in the absence of an abuse of discretion.
    5.   Pleadings: Judgments: Appeal and Error. A motion to alter or amend
    a judgment is addressed to the discretion of the trial court, whose deci-
    sion will be upheld in the absence of an abuse of that discretion.
    6.   Judges: Words and Phrases. A judicial abuse of discretion exists when
    the reasons or rulings of a trial judge are clearly untenable, unfairly
    depriving a litigant of a substantial right and denying just results in mat-
    ters submitted for disposition.
    7.   Arbitration and Award: Federal Acts: Contracts. Arbitration in
    Nebraska is governed by the Federal Arbitration Act if it arises from
    a contract involving interstate commerce; otherwise, it is governed by
    Nebraska’s Uniform Arbitration Act.
    8.   Jurisdiction: Appeal and Error. Before reaching the legal issues
    presented for review, it is the power and duty of an appellate court to
    determine whether it has jurisdiction over the matter before it.
    9.   Arbitration and Award: Federal Acts: Jurisdiction: Notice. The
    Federal Arbitration Act’s notice requirements are jurisdictional, and fail-
    ure to strictly comply deprives the district court of authority under the
    Federal Arbitration Act to vacate the arbitration award.
    10.   Arbitration and Award: Federal Acts: Notice. The Federal Arbitration
    Act’s notice requirements are satisfied if the notice provided complies
    with Nebraska’s statutory notice requirements.
    11.   Arbitration and Award: Federal Acts: Legislature. The Federal
    Arbitration Act favors arbitration agreements and applies in both state
    and federal courts. It also preempts conflicting state laws and fore-
    closes state legislative attempts to undercut the enforceability of arbitra-
    tion agreements.
    12.   Arbitration and Award: Motions to Vacate. When arbitration has
    already occurred and a party seeks to vacate, modify, or confirm an
    award, an extraordinary level of deference is given to the underlying
    award itself.
    13.   Arbitration and Award: Federal Acts: Motions to Vacate. The Federal
    Arbitration Act sets forth four grounds under which a court may vacate
    an arbitration award, and in the absence of one of these grounds, the
    award must be confirmed.

    14. Arbitration and Award: Federal Acts: Motions to Vacate: Proof.
    A party seeking to vacate an award for misconduct under 9 U.S.C.
    § 10(a)(3) (2018) of the Federal Arbitration Act must show that he or
    she was deprived of a fair hearing.
    15. Arbitration and Award: Federal Acts. Under 9 U.S.C. § 10(a)(2)
    (2018) of the Federal Arbitration Act, evident partiality exists where
    the nondisclosure at issue objectively demonstrates such a degree of
    partiality that a reasonable person could assume that the arbitrator had
    improper motives.
    16. Arbitration and Award: Federal Acts: Motions to Vacate. Under
    the Federal Arbitration Act, courts lack authority to vacate or modify
    arbitration awards on any grounds other than those specified in 9 U.S.C.
    §§ 10 and 11 (2018) of the Federal Arbitration Act.
    17. Arbitration and Award: Federal Acts: Motions to Vacate: Public
    Policy. Under the Federal Arbitration Act, a court is not authorized to
    vacate an arbitration award based on public policy grounds because
    public policy is not one of the exclusive statutory grounds set forth in 9
    U.S.C. § 10 (2018) of the Federal Arbitration Act.
    18. Arbitration and Award: Federal Acts: Contracts: Proof. Pursuant
    to 9 U.S.C. § 10(a)(4) (2018) of the Federal Arbitration Act, a court
    is authorized to set aside an arbitration award where the arbitrator
    exceeded his or her powers. However, it is not enough to show that the
    arbitrator committed an error—or even a serious error. The analysis is
    whether the arbitrator (even arguably) interpreted the parties’ contract,
    not whether he or she got its meaning right or wrong.
    19. Attorney Fees. Attorney fees shall be awarded against a party who
    alleged a claim or defense that the court determined was frivolous, inter-
    posed any part of the action solely for delay or harassment, or unneces-
    sarily expanded the proceeding by other improper conduct.
    20. Actions: Attorney Fees: Words and Phrases. A frivolous action is one
    in which a litigant asserts a legal position wholly without merit; that is,
    the position is without rational argument based on law and evidence to
    support the litigant’s position. The term frivolous connotes an improper
    motive or legal position so wholly without merit as to be ridiculous.
    21. Actions. Any doubt about whether a legal position is frivolous or taken
    in bad faith should be resolved in favor of the one whose legal position
    is in question.
    22. Appeal and Error. An appeal or error proceeding, properly perfected,
    deprives the trial court of any power to amend or modify the record as
    to matters of substance.
    23. Arbitration and Award: Federal Acts: Contracts. Under the Federal
    Arbitration Act, arbitration is a matter of contract, and courts must
    enforce arbitration contracts according to their terms.

    24. Arbitration and Award. An evident material mistake is an error that is
    apparent on the face of the record and would have been corrected had
    the arbitrator known at the time.
    25. Attorney Fees: Appeal and Error. Ordinarily, an improper calcula-
    tion of attorney fees would require a remand in order to reconfigure
    the award. However, when the record is sufficiently developed that a
    reviewing court can apply the law to the facts and calculate a fair and
    reasonable fee without resorting to remand, that route is available to the
    appellate court.
    26. Appeal and Error. An appellate court is not obligated to engage in an
    analysis that is not necessary to adjudicate the case and controversy
    before it.
    27. Judgments: Appeal and Error. Generally, under the acceptance of ben-
    efits rule, an appellant may not voluntarily accept the benefits of part of
    a judgment in the appellant’s favor and afterward prosecute an appeal or
    error proceeding from the part that is against the appellant.
    28. ____: ____. The acceptance of the benefits rule does not apply when
    the appellant has conceded to be entitled to the thing he or she has
    accepted and where the appeal relates only to an additional claim on his
    or her part.
    29. Judgments: Proof: Appeal and Error. In asserting that the accept­
    ance of benefits rule precludes an appeal, the burden is on the party
    asserting the rule to demonstrate that the benefits of the judgment were
    accepted.

    I. INTRODUCTION
    This is an appeal from a judgment of the district court for
    Douglas County, confirming an arbitration award of $2,997,031
    under the Federal Arbitration Act (FAA)1 and awarding attor-
    ney fees as a sanction under Neb. Rev. Stat. § 25-824 (Reissue
    2016).
    II. BACKGROUND
    These two cases arose out of an arbitration between family
    members designated as the “Omaha Seldins” and the “Arizona
    Seldins.” The term “Omaha Seldins” refers to the following
    individuals, entities, and trusts: Theodore M. Seldin, indi-
    vidually and in his capacity as trustee of the Amended and
    Restated Theodore M. Seldin Revocable Trust, dated May
    28, 2008; Howard Scott Silverman as trustee of the Amended
    and Restated Stanley C. Silverman Revocable Trust, dated
    August 26, 2006; Silverman Holdings, LLC, a Nebraska lim-
    ited liability company; SCS Family, LLC, a Nebraska limited
    liability company; TMS & SNS Family, LLC, a Nebraska
    limited liability company; Sarah N. Seldin and Irving B.
    Epstein, as trustees of the Theodore M. Seldin and Sarah N.
    Seldin Children’s Trust, dated January 1, 1995; Uri Ratner as
    trustee of the Stanley C. Silverman and Norma R. Silverman
    Irrevocable Trust Agreement (2008), dated April 10, 2008;
    John W. Hancock, Irving B. Epstein, and Randall R. Lenhoff
    as trustees of the Theodore M. Seldin and Sarah N. Seldin
    Irrevocable Trust Agreement (2008), dated May 12, 2008.
    The term “Arizona Seldins” refers to the following individ­
    uals, entities, and trusts: Millard R. Seldin, individually and
    as trustee of the Millard R. Seldin Revocable Trust, dated
    October 9, 1993; Scott A. Seldin, individually and as trustee
    of the Seldin 2002 Irrevocable Trust, dated December 13,
    2002; Seldin Real Estate, Inc., an Arizona corporation; Kent
    Circle Investments, LLC, an Arizona limited liability company;
    1
    9 U.S.C. §§ 1 through 16 (2018).

    and Belmont Investments, LLC, an Arizona limited liabil-
    ity company.
    For a period of more than 50 years, the parties held joint
    ownership interests as the Seldin Company in numerous enti-
    ties located in the Omaha, Nebraska, area. The three princi-
    pals of the Seldin Company were Millard; Millard’s younger
    brother, Theodore; and Millard’s brother-in-law, Stanley C.
    Silverman. The Seldin Company’s principal place of busi-
    ness was Omaha. However, in 1987, Millard began relocating
    the business operations from Omaha to Scottsdale, Arizona.
    Theodore and Stanley co-owned the company, and they agreed
    to manage the jointly owned properties through management
    agreements.
    In 2007, the Arizona Seldins (specifically Millard and
    Millard’s son, Scott) began to question how Theodore and
    Stanley were managing the jointly owned properties. In 2010,
    the Arizona Seldins terminated the management agreements
    and the parties entered into an agreement to separate their
    joint interests in real estate assets through a bidding process.
    The “Separation Agreement” included a provision whereby the
    parties agreed to resolve all “Ancillary Claims” exclusively
    through binding arbitration before arbitrator Stefan Tucker
    with the Venable, LLP, law firm in Washington, D.C. In case
    of Tucker’s inability to serve as arbitrator, the agreement
    named a Venable partner as his successor. If both Tucker and
    the successor were unable to serve as arbitrator, the agreement
    provided that Venable’s managing partner was responsible for
    identifying a substitute successor. The agreement also included
    provisions defining the scope of arbitration, as well as a provi-
    sion that the “Commercial Division Rules” of the American
    Arbitration Association (AAA) would govern.
    After the bidding process was completed, the parties began
    arbitration before Tucker in October 2011. While the arbitra-
    tion was ongoing, the Arizona Seldins filed three lawsuits in
    the district court for Douglas County regarding their claims or,
    alternatively, seeking to remove Tucker as arbitrator. The dis-
    trict court dismissed the lawsuits and compelled the Arizona
    - 191 -

    305 Neb. 185
    Seldins back to arbitration after finding the FAA governed the
    arbitration provision in the agreement. The Arizona Seldins
    then filed a demand with the AAA, seeking to disqualify
    Tucker as the arbitrator. The AAA denied the request; how-
    ever, Tucker subsequently resigned and neither the succes-
    sor arbitrator nor Venable was willing to participate in the
    arbitration. The parties agreed to select an arbitrator through
    the AAA, and Eugene R. Commander (hereinafter arbitrator)
    was appointed.
    Arbitration resumed in October 2013. Due to the number
    of claims, each involving several independent causes of action
    and affirmative defenses, the arbitrator proposed bifurcating
    each claim to address liability and damage claims in separate
    hearings when necessary. The parties agreed to the proposal,
    and a schedule of hearings was adopted.
    After extensive discovery was conducted, 11 evidentiary
    hearings took place over a span of 14 months. Pursuant to
    the separation agreement, the hearings took place in Omaha.
    During the 53 days of hearings, 58 fact and expert witnesses
    testified and 1,985 exhibits were admitted into evidence. As
    permitted by the AAA’s rules,2 the arbitrator issued 12 separate
    interim awards at the end of hearings in which determinations
    of liability or damages had been made. The parties agreed that
    these interim awards were not considered final awards and that
    a final award would be issued after the arbitration had closed.
    The parties also agreed that the entities and individuals that
    made up each of the two parties were jointly and severally
    liable for any award issued by the arbitrator.
    At some point during the arbitration proceedings, the Arizona
    Seldins asserted that the Omaha Seldins’ lack of tender of one
    of its assets, Sky Financial Securities, LLC (Sky Financial),
    was a defense to damages under the Arizona Securities Act.
    Sky Financial is an Arizona limited liability company, cre-
    ated as part of a plan to acquire and operate a chain of pizza

    Mediation Procedures R-37 at 24 (Oct. 1, 2013).

    restaurants in numerous states. In response, the Omaha Seldins
    requested that the arbitrator take possession of Sky Financial
    as a form of interpleader so as to permit the award of the asset
    to the appropriate party after a determination was made. The
    Arizona Seldins did not object to the procedure, and when
    asked whether the assignment as a form of interpleader was
    acceptable to both sides, the Arizona Seldins stated, “Yes.” The
    Omaha Seldins then tendered Sky Financial to the arbitrator
    by assignment.
    In one of the interim awards, the arbitrator determined that
    the Arizona Seldins had breached their fiduciary duties and
    engaged in securities law violations relating to Sky Financial.
    After finding that none of the affirmative defenses raised by the
    Arizona Seldins were meritorious, the arbitrator awarded the
    Omaha Seldins $1,962,528 in damages for their lost corporate
    opportunities claims, as well as an additional $3,135,681 in
    recessionary damages for the securities violation claims.
    On April 12, 2017, the arbitration was officially closed.
    On April 27, the arbitrator issued a final net award in favor
    of the Omaha Seldins and against the Arizona Seldins in the
    amount of $2,997,031, plus postaward simple interest. The
    final award incorporated each of the prior interim awards
    issued and found the Arizona Seldins jointly and severally
    liable for the entire amount.
    On May 23, 2017, the Omaha Seldins filed a motion to con-
    firm the final award in district court. Opposing confirmation,
    the Arizona Seldins filed a motion seeking to modify, correct,
    and/or vacate the award. The Arizona Seldins argued, summa-
    rized, that the arbitrator (1) engaged in misbehavior regarding
    assignment of the Sky Financial asset, and thus the Omaha
    Seldins lacked standing after the assignment; (2) failed to
    provide a reasoned award on three of the Arizona Seldins’ key
    affirmative defenses; (3) exceeded his power in awarding legal
    fees and expenses to the Omaha Seldins, because the separa-
    tion agreement precluded the award of attorney fees; and (4)
    materially miscalculated the amount of prejudgment interest by
    applying the incorrect interest rate or, alternatively, exceeded
    - 193 -

    SELDIN v. ESTATE OF SILVERMAN
    Cite as 
    305 Neb. 185
    his power in awarding damages that included the calculated
    amount of prejudgment interest.
    Scott, one of the Arizona Seldins, sought further and sepa-
    rate relief. Scott argued that with regard to the Sky Financial
    claims, the arbitrator made an “evident material mistake in
    the description of ‘Respondents’” and made an award on mat-
    ters not submitted to him. Scott alternatively argued that the
    arbitrator exceeded his power or imperfectly executed it, by
    issuing an award of liability against Scott on those claims. In
    addition, Scott filed multiple applications seeking to vacate,
    confirm, and/or modify some of the interim awards in com-
    panion cases CI 16-7509, CI 16-8394, CI 17-506, CI 17-651,
    and CI 17-3637. The district court held that the interim
    awards were nonfinal arbitration orders and dismissed the
    applications.
    On May 3, 2018, the district court issued an order sustain-
    ing the Omaha Seldins’ motion to confirm the arbitration
    award and overruling the Arizona Seldins’ motion to vacate the
    award. The district court also awarded the Omaha Seldins
    an amount equal to the attorneys’ fees and costs [the
    Omaha Seldins] incurred in resisting [the Arizona
    Seldins’] application seeking vacation or modification
    of the Final Award and in seeking dismissal of the vari-
    ous applications (Case Nos. CI 16-7509; CI 16-8394;
    CI 17-506; CI 17-651; and CI 17-3637) . . . Scott . . . filed
    seeking to modify, vacate, or confirm the Arbitrator’s
    Interim Awards [under Neb. Rev. Stat. “§ 25-834”].
    The district court had mistakenly referred to the statute autho-
    rizing the sanction as Neb. Rev. Stat. § 25-834 (Reissue 1995),
    instead of § 25-824.
    On July 30, 2018, the Omaha Seldins offered into evi-
    dence affidavits with attached fee statements from two law
    firms, demonstrating the amount of fees incurred on behalf of
    the Omaha Seldins in resisting the Arizona Seldins’ motion
    to vacate and in seeking dismissal of Scott’s interim award
    applications. The affidavits established that the law firm of
    McGill, Gotsdiner, Workman & Lepp, P.C., L.L.O. (McGill),
    - 194 -
    Nebraska Supreme Court Advance Sheets
    305 Nebraska Reports
    SELDIN v. ESTATE OF SILVERMAN
    Cite as 
    305 Neb. 185
    had incurred $131,184.45 in fees and that the law firm of
    Bryan Cave Leighton Paisner LLP (Bryan Cave) had incurred
    $211,676.50 in fees, both on behalf of the Omaha Seldins. The
    exhibit containing the McGill firm’s statement of fees had been
    redacted for privilege purposes. At a subsequent hearing, the
    Omaha Seldins offered an unredacted version of the McGill
    firm’s fee statement, which the court received into evidence
    under seal.
    On February 28, 2019, the district court issued its order
    denying the Arizona Seldins’ and Scott’s motions to alter or
    amend. In the same order, the district court awarded the Omaha
    Seldins attorney fees in the amount of $131,184.45.
    On June 3, 2019, the Omaha Seldins filed a motion for
    order nunc pro tunc, requesting that the district court modify
    the amount of attorney fees to include Bryan Cave’s fees of
    $211,676.50, for a total award of $342,860.95. After a hear-
    ing on the motion, in a written order dated August 26, 2019,
    the district court denied the Omaha Seldins’ motion for order
    nunc pro tunc. In its order, the district court stated that it had
    “clearly intended to award attorney fees to [the Omaha Seldins]
    in an amount, as stated in the Court’s Order of February 28,
    2019, equal to the attorney fees and costs incurred,” but denied
    the motion after concluding that “[a]n Order Nunc Pro Tunc
    [could not] be used to enlarge the judgment or substantially
    amend[] the judgment even though said judgment was not the
    order intended.”
    On May 11, 2018, Scott filed a motion to alter or amend
    the district court’s May 3 order. Scott argued that the award of
    attorney fees and costs was beyond the amount permitted as
    damages and that the arbitrator’s award of attorney fees was
    improper. The motion further asserted that the order had refer-
    enced § 25-834 as authorizing the sanction against the Arizona
    Seldins, but that § 25-834 is unrelated to an award of attorney
    fees and had been repealed by the Legislature in 2002.
    The Arizona Seldins also filed a motion to alter or amend
    the order. The motion incorporated Scott’s arguments and
    additionally asserted that the district court failed to specifically
    - 195 -

    305 Nebraska Reports
    SELDIN v. ESTATE OF SILVERMAN
    Cite as 
    305 Neb. 185
    address some of the Arizona Seldins’ prior arguments, includ-
    ing whether the final award violated the automatic bankruptcy
    stay, whether the final award violated Nebraska’s public policy
    and resulted in a massive windfall to the Omaha Seldins, and
    whether the arbitrator engaged in evident partiality.
    On February 28, 2019, the district court issued a 13-page
    order detailing its findings and overruling both motions to
    alter or amend the May 3, 2018, order. The February 28,
    2019, order included a nunc pro tunc modification, substituting
    § 25-824 for the references to § 25-834 in the previous order.
    When discussing the sanction ordered against the Arizona
    Seldins, the district court noted that its May 3, 2018, order had
    “repeatedly identified the absence of rational factual or legal
    basis to support [the Arizona Seldins’] theories of modifying
    or vacating the Final Award.” The district court articulated
    that “[w]hat should have been a fairly simple procedure, [the
    Arizona Seldins] literally turned into a re-litigation of the
    Arbitration itself.”
    The Arizona Seldins appeal the district court’s order con-
    firming the award and the district court’s order of sanctions
    under § 25-824. Scott, individually, filed a cross-appeal assert-
    ing that the final award against him should be modified, cor-
    rected, or vacated by law and that the district court abused its
    discretion in imposing sanctions and overruling his motion to
    alter or amend. The Omaha Seldins also filed a cross-appeal,
    challenging the amount of attorney fees and costs ordered by
    the district court and the district court’s denial of the Omaha
    Seldins’ motion for order nunc pro tunc. The Arizona Seldins
    subsequently filed a motion to dismiss the Omaha Seldins’
    cross-appeal, claiming the Omaha Seldins’ registration of the
    district court’s judgment with an Arizona state court constituted
    an acceptance of the benefits of the judgment and, thus, pre-
    cluded them from appealing the judgment.
    We granted the parties’ petition to bypass the Nebraska
    Court of Appeals, and the two cases, S-19-0310 and S-19-0311,
    have been consolidated for purposes of oral argument and
    disposition.

    III. ASSIGNMENTS OF ERROR
    The Arizona Seldins’ assignments, renumbered and restated,
    are that the district court erred in (1) failing to vacate the Sky
    Financial award because the award was secured through mis-
    behavior by the arbitrator; (2) failing to vacate the final award
    because the Sky Financial award violates Nebraska public pol-
    icy by creating a massive windfall for the Omaha Seldins; (3)
    confirming the arbitrator’s award of attorney fees because the
    award exceeded the scope of the separation agreement, which
    expressly prohibited an award of attorney fees; (4) awarding
    sanctions under § 25-824; and (5) excluding evidence of the
    Omaha Seldins’ acting contrary to the separation agreement
    and the award by currently seeking additional damages in other
    litigation for the same Sky Financial investment.
    Scott’s assignments of error on cross-appeal, summarized,
    are that the district court erred in (1) failing to modify or cor-
    rect an evident material mistake in the description of respond­
    ents in the final award relating to him; (2) failing to vacate the
    final award on the ground of arbitrator misbehavior; (3) fail-
    ing to vacate the final award on the ground that the arbitrator
    exceeded his authority in regard to the claims bar date; and (4)
    imposing sanctions pursuant to § 25-824 and denying Scott’s
    motion to alter or amend the district court’s order regarding
    the sanctions.
    The Omaha Seldins assign on cross-appeal that the district
    court erred in (1) denying their motion for order nunc pro
    tunc and (2) failing to award the Omaha Seldins their reason-
    able attorney fees and costs incurred. While not specifically
    assigned as error, the Omaha Seldins also assert that the
    Arizona Seldins’ public policy argument is time barred.
    IV. STANDARD OF REVIEW
    [1] A jurisdictional question which does not involve a factual
    dispute is determined by an appellate court as a matter of law.3

    [2] In reviewing a decision to vacate, modify, or confirm an
    arbitration award under the FAA, an appellate court is obligated
    to reach a conclusion independent of the trial court’s ruling as
    to questions of law.4 However, the trial court’s factual findings
    will not be set aside on appeal unless clearly erroneous.5
    [3,4] On appeal, a trial court’s decision awarding or deny-
    ing attorney fees will be upheld absent an abuse of discretion.6
    When an attorney fee is authorized, the amount of the fee is
    addressed to the discretion of the trial court, whose ruling
    will not be disturbed on appeal in the absence of an abuse of
    discretion.7
    [5] A motion to alter or amend a judgment is addressed to
    the discretion of the trial court, whose decision will be upheld
    in the absence of an abuse of that discretion.8
    [6] A judicial abuse of discretion exists when the reasons or
    rulings of a trial judge are clearly untenable, unfairly depriving
    a litigant of a substantial right and denying just results in mat-
    ters submitted for disposition.9
    V. ANALYSIS
    1. Appeal Is Governed by FAA
    [7] Prior to addressing the arbitration issues raised by the
    parties on appeal, we must determine which law governs—the
    Uniform Arbitration Act (UAA)10 or the FAA. Arbitration in
    Nebraska is governed by the FAA if it arises from a contract
    involving interstate commerce; otherwise, it is governed by the

    UAA.11 The district court determined that the issues presented
    in this case were governed by the FAA. We agree. Arbitration
    that arises from a contract involving interstate commerce is
    governed by the FAA.12 Because this case arose from a com-
    mercial dispute involving properties and companies located in
    multiple states, the arbitration agreement clearly involves inter-
    state commerce and thus is governed by the FAA.
    2. Motion to Vacate Was Timely
    [8] Before reaching the legal issues presented for review,
    it is the power and duty of an appellate court to determine
    whether it has jurisdiction over the matter before it.13 The
    Omaha Seldins claim the Arizona Seldins are precluded from
    seeking modification or vacatur of the final award on public
    policy grounds because this argument was not raised within 3
    months of the final order being issued as required by § 12 of
    the FAA.
    [9] Section 12 of the FAA sets forth the specific service
    requirements for motions to vacate, modify, or correct an
    award and requires notice of an application seeking judicial
    vacatur to “be served upon the adverse party or his attorney
    within three months after the award is filed or delivered.” This
    court has held that these notice requirements are jurisdictional
    and that failure to strictly comply deprives the district court
    of authority under the FAA to vacate the arbitration award.14
    And, where the district court lacks jurisdiction, this court lacks
    jurisdiction.15
    The relevant portion of § 12 provides:
    Notice of a motion to vacate, modify, or correct an
    award must be served upon the adverse party or his

    attorney within three months after the award is filed or
    delivered. If the adverse party is a resident of the district
    within which the award was made, such service shall be
    made upon the adverse party or his attorney as prescribed
    by law for service of notice of motion in an action in
    the same court. If the adverse party shall be a nonresi-
    dent then the notice of the application shall be served
    by the marshal of any district within which the adverse
    party may be found in like manner as other process of
    the court.
    [10] Thus, the FAA’s notice requirements are satisfied if
    the notice provided complies with Nebraska’s statutory notice
    requirements. Neb. Rev. Stat. § 25-910 (Reissue 2016) requires
    that the notice be in writing and provides that it
    shall state (1) the names of the parties to the action or
    proceeding in which it is to be made, (2) the name of
    the court or judge before whom it is to be made, (3) the
    place where and the day on which it will be heard, (4)
    the nature and terms of the order or orders to be applied
    for, and (5) if affidavits are to be used on the hearing, the
    notice shall state that fact. It shall be served a reasonable
    time before the hearing.
    The record reflects that the final arbitration award was
    issued on April 27, 2017. The Arizona Seldins moved to mod-
    ify, correct, or vacate the award on July 25. On the same day,
    the Arizona Seldins provided the other parties with notice of
    the motion via U.S. mail and electronic mail. While the motion
    did not specifically assert the Arizona Seldins’ public policy
    argument, the notice included each of the five requirements
    set forth in § 25-910 and was provided within 3 months of the
    final order being issued. The Arizona Seldins’ notice complied
    with Nebraska’s statutory notice requirements; thus, the notice
    requirements under § 12 of the FAA were satisfied. The public
    policy argument was timely raised, and therefore, this court has
    jurisdiction over the claim.

    3. Claims by Arizona Seldins
    and Scott
    (a) Arbitrator Misbehavior
    In their first assignment of error, the Arizona Seldins claim
    the district court erred in failing to vacate the Sky Financial
    award because the award was secured through misbehavior by
    the arbitrator. On cross-appeal, Scott also asserts that the arbi-
    trator’s acceptance of Sky Financial constituted misconduct.
    Scott further asserts that the Arizona Seldins could not have
    accepted or consented to the interpleader because the transfer
    abrogated the Omaha Seldins’ interest in Sky Financial and
    thus the interpleader never existed. Scott also claims that the
    interpleader procedure was not disclosed or explained and that
    he “should not be bound by a secret interpleader procedure of
    which he was never informed since he had no need for concern
    regarding any securities claim at the time the purported inter-
    pleader was first proposed for that purpose.”16
    [11,12] Congress enacted the FAA to provide for “expe-
    dited judicial review to confirm, vacate, or modify arbitration
    awards.”17 The FAA favors arbitration agreements and applies
    in both state and federal courts.18 It also preempts conflict-
    ing state laws and “‘foreclose[s] state legislative attempts to
    undercut the enforceability of arbitration agreements.’”19 When
    arbitration has already occurred and a party seeks to vacate,
    modify, or confirm an award, “‘“an extraordinary level of
    deference” [is given] to the underlying award itself.’”20 The
    U.S. Supreme Court has instructed that under the FAA, a court

    may vacate an arbitrator’s decision “‘only in very unusual
    circumstances.’”21
    [13] The FAA sets forth four grounds under which a court
    may vacate an arbitration award, and in the absence of one of
    these grounds, the award must be confirmed.22 These grounds
    are as follows:
    (1) where the award was procured by corruption, fraud,
    or undue means;
    (2) where there was evident partiality or corruption in
    the arbitrators, or either of them;
    (3) where the arbitrators were guilty of misconduct in
    refusing to postpone the hearing, upon sufficient cause
    shown, or in refusing to hear evidence pertinent and mate-
    rial to the controversy; or of any other misbehavior by
    which the rights of any party have been prejudiced; or
    (4) where the arbitrators exceeded their powers, or
    so imperfectly executed them that a mutual, final, and
    definite award upon the subject matter submitted was not
    made.23
    Both the Arizona Seldins and Scott claim the arbitra-
    tor engaged in misbehavior by accepting ownership of Sky
    Financial. We reject this claim because the Arizona Seldins
    expressly agreed to the transfer of Sky Financial during the
    arbitration proceedings, and there is no evidence that the arbi-
    trator engaged in misconduct by accepting the transfer.
    The Omaha Seldins attempted to “tender” Sky Financial as
    a form of interpleader after the Arizona Seldins asserted that a
    lack of tender is a defense under the Arizona Securities Act in
    regard to damages. The Omaha Seldins transferred ownership
    of Sky Financial to the arbitrator “‘for purposes of effectuat-
    ing the relief to be awarded.’” The relief contemplated was the

    award of the asset to the appropriate party after a determination
    had been made.
    At the time the assignment was made, the following collo-
    quy occurred:
    ARBITRATOR: Well, I’m in uncharted waters here.
    I guess my first question is why would the assignment
    come to me?
    [Counsel for the Omaha Seldins]: It’s largely in the
    sense of an interpleader. Is this to be — I mean, it empha-
    sizes the point which is the impossibility, to whom do
    we tender, do we tender to Millard, do we tender to Sky
    Financial, to whomever it is that it is deemed you think,
    to the extent it isn’t impossible and excused by impos-
    sibility, you’re welcome to determine to whomever it
    should be tendered.
    ....
    ARBITRATOR: Well, the only way I know how to deal
    with this right now is to consider this an act of interplead-
    ing these interests to me. I’m not an officer of the court,
    but I do have jurisdiction over this matter, so for the time
    being, at least, I’ll accept them. With that understanding
    in mind. Is that acceptable to both sides?
    [Counsel for the Arizona Seldins]: Yes.
    [14] “A party seeking to vacate an award for misconduct
    under § 10(a)(3) must show that he [or she] was ‘deprived of a
    fair hearing.’”24 When a party “‘who contests the merits of an
    arbitration award in court fails to first present the challenges on
    the merits to the arbitrators themselves, review is compressed
    still further, to nil.’”25 Here, the district court noted that the
    Arizona Seldins appeared to have consented to the arbitra-
    tor’s acceptance of the assignment as a form of interpleader.

    We agree. Not only did the Arizona Seldins not object to the
    assignment at the time it was made, but they agreed that the
    transfer as an act of interpleading was acceptable after the
    purpose of the procedure was explained. By consenting to
    the assignment, the Arizona Seldins waived the argument that
    the arbitrator’s acceptance of the transfer constituted miscon­
    duct. And, the record clearly refutes Scott’s claim that the
    intended interpleader was not disclosed or explained.
    [15] Furthermore, while the Arizona Seldins’ attempt to
    invoke the grounds set forth in § 10(a)(3) of the FAA by using
    the term “misconduct,” their argument focuses only on the
    arbitrator’s possible partiality as the purported owner of Sky
    Financial. Under § 10(a)(2), a court may vacate an award for
    the arbitrator’s “evident partiality.” However, this is a “‘heavy
    burden’”26 because the standard “‘is not made out by the
    mere appearance of bias.’”27 “Evident partiality exists where
    the non-disclosure at issue ‘objectively demonstrate[s] such a
    degree of partiality that a reasonable person could assume that
    the arbitrator had improper motives.’”28
    The Arizona Seldins assert that the arbitrator’s taking actual
    possession of Sky Financial without first securing mutual con-
    sent of the parties in writing and making it part of the record
    disqualified him as an interested party under Neb. Rev. Stat.
    § 24-739 (Reissue 2016). Section 24-739 provides, in relevant
    part, that a judge shall be disqualified in any case in which he
    or she is a party or interested except by mutual consent of the
    parties, which mutual consent is in writing and made part of
    the record.
    The Arizona Seldins contend that § 24-739 applies to arbitra-
    tors as well as judges per this court’s instruction that “‘judges

    and arbitrators are subject to the same ethical standards.’”29
    However, this court has expressly rejected a “judicial ethics”
    standard when analyzing the FAA’s requirement of “evident
    partiality.” In Dowd v. First Omaha Sec. Corp.,30 we held that
    “‘“evident partiality” within the meaning of 9 U.S.C. § 10 will
    be found where a reasonable person would have to conclude
    that an arbitrator was partial to one party to the arbitration.’”
    Here, the record contains no evidence that the arbitrator
    engaged in misconduct or partiality by accepting the assignment
    of Sky Financial. Rule R-37(a) of the AAA rules, which was
    incorporated into the parties’ separation agreement, provides
    that “[t]he arbitrator may take whatever interim measures he or
    she deems necessary, including injunctive relief and meas­ures
    for the protection or conservation of property and disposition
    of perishable goods.” Moreover, the Arizona Seldins’ argument
    that the arbitrator’s acceptance of Sky Financial constituted
    misconduct is confuted by their express acceptance of the pro-
    cedure. This argument is without merit.
    (b) Public Policy
    In their second assignment of error, the Arizona Seldins
    assert that the district court erred in failing to vacate the final
    award because the Sky Financial award violates Nebraska
    public policy by creating a massive windfall for the Omaha
    Seldins. The Arizona Seldins argue that the Omaha Seldins
    profited substantially from Sky Financial and that the award
    of damages results in a double recovery and windfall for the
    Omaha Seldins in violation of public policy. The Arizona
    Seldins further assert that a court may refuse to enforce an
    arbitration award on the ground that it is contrary to public
    29

    policy. In making this assertion, the Arizona Seldins rely on
    this court’s prior holding in State v. Henderson.31
    In Henderson, a Nebraska State Patrol officer had been ter-
    minated based on his membership in a Ku Klux Klan-affiliated
    organization. An arbitrator determined that the State Patrol had
    violated the officer’s constitutional rights because his affilia-
    tion with the organization was not “‘just cause’” for termina-
    tion.32 The arbitrator issued an award ordering the officer to be
    reinstated.33 The district court vacated the award after conclud-
    ing that the officer’s reinstatement violated Nebraska public
    policy, and this court affirmed the judgment.34
    Unlike the present case, Henderson was governed by
    Nebraska’s UAA.35 However, this court found none of the
    UAA’s statutory bases for vacating an award applied.36 Noting
    that the applicable provisions in the UAA and the FAA were
    similar, the majority, in a 4-to-2 decision, relied on three U.S.
    Supreme Court cases applying the FAA when holding that an
    arbitration award could be vacated on public policy grounds.37
    The majority in Henderson held that a court may refuse
    to enforce an arbitration award that is contrary to a public
    policy when the policy is explicit, well defined, and domi-
    nant. The majority concluded that Nebraska has “an explicit,
    well-defined, and dominant public policy” that “the laws of
    Nebraska should be enforced without racial or religious dis-
    crimination” and that the arbitrator’s decision reinstating the
    officer violated this public policy because the policy “incor-
    porates, and depends upon, the public’s reasonable perception

    that the laws are being enforced without discrimination.”38 The
    dissent argued that the U.S. Supreme Court’s narrow public
    policy exception did not bar judicial enforcement of the award
    and that the majority was doing precisely what the Supreme
    Court had prohibited in Paperworkers v. Misco, Inc.39: engag-
    ing in factfinding, which is the arbitrator’s function, not the
    appellate court’s.40
    [16] Prior to 2008, a circuit split existed on whether courts
    could apply nonstatutory standards when reviewing arbitra-
    tion awards under the FAA. Many courts had been relying on
    language in the 1953 case of Wilko v. Swan,41 which indicated
    courts could vacate an award made in “manifest disregard” of
    the law. In Hall Street Associates, L. L. C. v. Mattel, Inc.,42
    the U.S. Supreme Court resolved the split and held that under
    the FAA, courts lack authority to vacate or modify arbitration
    awards on any grounds other than those specified in §§ 10 and
    11 of the FAA.43 The Court was explicit that
    [o]n application for an order confirming the arbitration
    award, the court “must grant” the order “unless the award
    is vacated, modified, or corrected as prescribed in sec-
    tions 10 and 11 of this title.” There is nothing malleable
    about “must grant,” which unequivocally tells courts to

    grant confirmation in all cases, except when one of the
    “prescribed” exceptions applies.44
    Pointedly, the Eighth Circuit Court of Appeals has explained
    that prior to 2008, “a court could vacate arbitration awards
    on grounds other than those listed in the FAA.”45 However,
    “Hall Street, resolving a circuit split, held that ‘the text [of
    the FAA] compels a reading of the §§ 10 and 11 categories as
    exclusive.’”46
    [17] Because the U.S. Supreme Court’s decision in Hall
    Street Associates, L. L. C. abrogated public policy as grounds
    for vacating an arbitration award under the FAA, we reject
    the Arizona Seldins’ argument. We hold that under the FAA, a
    court is not authorized to vacate an arbitration award based on
    public policy grounds because public policy is not one of the
    exclusive statutory grounds set forth in § 10 of the FAA. We
    also clarify that Henderson was governed by the UAA–-not the
    FAA–-and expressly disapprove of any language in Henderson
    that could be construed as authorizing courts to vacate awards
    on public policy grounds under the FAA.47
    Because public policy is not a ground for vacating an arbi-
    tration award under the FAA, we need not address the merits
    of the Arizona Seldins’ argument that the purported windfall in
    favor of the Omaha Seldins is contrary to public policy.
    (c) Arbitrator’s Award of
    Fees and Costs
    In their third assignment of error, the Arizona Seldins argue
    that the district court erred in confirming the arbitrator’s award
    of attorney fees because the award exceeded the scope of the
    separation agreement.

    [18] Pursuant to § 10(a)(4) of the FAA, a court is authorized
    to set aside an arbitration award where the arbitrator exceeded
    his or her powers. However, “‘[i]t is not enough . . . to show
    that the [arbitrator] committed an error—or even a serious
    error.’”48 The analysis is “whether the arbitrator (even argu-
    ably) interpreted the parties’ contract, not whether he got its
    meaning right or wrong.”49 “Because the parties ‘bargained
    for the arbitrator’s construction of their agreement,’ an arbitral
    decision ‘even arguably construing or applying the contract’
    must stand, regardless of a court’s view of its (de)merits.”50
    In the final award, the arbitrator ordered the parties to pay
    their own attorney fees, expenses, and costs arising from
    the arbitration proceedings, “[e]xcept as specifically provided
    in Supplemental Interim Award Claim 16,” which awarded
    $1,001,051 in attorney fees and costs to the Omaha Seldins as
    a partial measure of the damages caused by securities viola-
    tions related to Sky Financial. The Arizona Seldins assert that
    the award of attorney fees exceeded the scope of the separa-
    tion agreement because the agreement expressly prohibited
    such an award.
    This assertion is based on a provision of the separation
    agreement, which states:
    In General: Except as otherwise provided in this
    Agreement, each Party shall bear its own costs and
    expenses (including legal fees and expenses) incurred in
    connection with this Agreement and the transactions con-
    templated hereby. No party shall be required to pay to the
    other Party any commissions, penalties, fees or expenses
    arising out of or associated with any of the transactions
    contemplated by this Agreement.

    In “Supplemental Interim Award Claim 16,” the arbitrator
    interpreted the parties’ agreement regarding the award of fees
    and costs and found that the agreement did not preclude an
    award of fees and costs incurred in prosecuting the lost corpo-
    rate opportunity and securities violations claims related to Sky
    Financial. The arbitrator concluded that the agreement’s “trans-
    actions contemplated” language referred to the transactions and
    process contemplated by the parties in separating their joint
    ownership interests in the jointly owned properties and entities
    and not ancillary claims.
    The arbitrator’s conclusion was based, in part, on the loca-
    tion of the provision within the separation agreement, and
    on another provision which stated: “Cooperation. The Parties
    acknowledge and agree that the transactions contemplated by
    this Agreement are intended to permit the Omaha Seldins, on
    the one hand, and the Arizona Seldins, on the other hand, to
    separate their joint ownership of the Properties.” In addition,
    the arbitrator found that the rules of the AAA, which the par-
    ties had incorporated into the separation agreement, authorized
    the award of attorney fees and costs under circumstances such
    as those presented here.
    We hold that the arbitrator did not exceed his authority
    under the separation agreement by issuing the award of fees
    and costs. In the parties’ separation agreement, the parties each
    agreed to resolve their disputes relating to severing their jointly
    owned properties through final and binding arbitration. By
    entering into the agreement, the parties bargained for the arbi-
    trator’s construction of that agreement. The arbitrator construed
    the agreement as permitting the award of attorney fees for the
    parties’ ancillary claims. The Sky Financial claim was an ancil-
    lary claim, and thus, the arbitrator did not exceed his authority
    in awarding costs and fees related to that claim. The Arizona
    Seldins’ third assignment of error is without merit.
    (d) Sanctions Under § 25-824
    In their fourth assignment of error, the Arizona Seldins
    argue that the district court erred in awarding sanctions against
    - 210 -

    them under § 25-824. Scott individually asserts on cross-
    appeal that the district court abused its discretion in impos-
    ing sanctions against Scott for filing the various applica-
    tions in CI 16-7509, CI 16-8394, CI 17-506, CI 17-651, and
    CI 17-3637 and in overruling his motion to alter or amend the
    district court’s order.
    Section 25-824(2) provides that
    in any civil action commenced or appealed in any court
    of record in this state, the court shall award as part of its
    judgment and in addition to any other costs otherwise
    assessed reasonable attorney’s fees and court costs against
    any attorney or party who has brought or defended a civil
    action that alleges a claim or defense which a court deter-
    mines is frivolous or made in bad faith.
    [19-21] We have stated that attorney fees shall be awarded
    against a party who alleged a claim or defense that the court
    determined was frivolous, interposed any part of the action
    solely for delay or harassment, or unnecessarily expanded the
    proceeding by other improper conduct.51 A frivolous action is
    one in which a litigant asserts a legal position wholly without
    merit; that is, the position is without rational argument based
    on law and evidence to support the litigant’s position.52 The
    term “frivolous” connotes an improper motive or legal posi-
    tion so wholly without merit as to be ridiculous.53 Any doubt
    about whether a legal position is frivolous or taken in bad faith
    should be resolved in favor of the one whose legal position is
    in question.54
    In seeking to modify or vacate the final award, the Arizona
    Seldins asserted four arguments. As previously summarized,
    these arguments were that the arbitrator (1) engaged in mis-
    behavior relating to the assignment of the Sky Financial

    property, (2) failed to provide a reasoned award on three
    affirmative defenses raised by the Arizona Seldins related to
    the Sky Financial claims, (3) exceeded his power in award-
    ing legal fees and expenses to the Omaha Seldins, and (4)
    materially miscalculated the prejudgment interest when award-
    ing damages.
    In its May 3, 2018, order, the district court entered judgment
    in favor of the Omaha Seldins and against the Arizona Seldins
    under § 25-824. When evaluating the Arizona Seldins’ claim
    that the arbitrator engaged in misbehavior, the district court
    noted that the Arizona Seldins appeared to have consented to
    the assignment of Sky Financial, they had presented no evi-
    dence demonstrating the arbitrator had improper motives when
    accepting the assignment of Sky Financial, and their argument
    “conflicts with the facts and the law.”
    With regard to the argument that the arbitrator had failed to
    provide a reasoned award in relation to the Arizona Seldins’
    affirmative defense involving the claims bar date, the district
    court found this argument lacked merit and “mischaracterize[d]”
    the significance of the relation-back doctrine under Fed. R.
    Civ. P. 15. In doing so, the district court called attention to
    the arbitrator’s written findings and awards relating to the Sky
    Financial claim, which consisted of 60 pages and contained
    multiple paragraphs explaining the arbitrator’s reasoning when
    rejecting the defense.
    The district court also rejected the argument that the arbitra-
    tor exceeded his power when awarding legal fees and expenses.
    Recognizing that the cases cited by the Arizona Seldins when
    asserting this argument either did not support their argument
    or were not relevant, the district court found the arbitrator
    had correctly interpreted and applied the separation agreement
    when awarding the fees and costs.
    The district court characterized the Arizona Seldins’ argu-
    ment that the arbitrator had materially miscalculated the pre-
    judgment interest as “misleading” and “fundamentally mis-
    placed.” Noting that allegations of an arbitrator’s legal error
    - 212 -
    Nebraska Supreme Court Advance Sheets
    305 Nebraska Reports
    SELDIN v. ESTATE OF SILVERMAN
    Cite as 
    305 Neb. 185
    are not reviewable, the district court found that the Arizona
    Seldins had failed to identify any “‘mathematical error’” in the
    arbitrator’s calculations. The court recognized that in making
    this assertion, the Arizona Seldins were attempting to chal-
    lenge the merits of the final award by arguing that the arbitra-
    tor had committed legal error.
    Addressing Scott’s individual claims, the district court found
    there was no legal basis for Scott’s challenge of the interim
    awards as the parties had agreed that the arbitrator’s interim
    awards were nonfinal. Further, each of the 12 interim awards
    included the following statement: “The parties understand this
    Interim Award is not a final appealable arbitration award, but
    it will be part of the law of the case moving forward.” Still,
    Scott proceeded to file lawsuits seeking to modify, vacate,
    and/or confirm five of these awards. In addition to finding the
    interim applications frivolous, the district court found Scott’s
    argument that he should not be held jointly and severally liable
    to be “misleading.”
    Reviewing the record and arguments in this case, we agree
    with the district court in that “[w]hat should have been a fairly
    simple procedure, [the Arizona Seldins] literally turned into a
    re-litigation of the Arbitration itself.” The district court issued
    the § 25-824 sanction after repeatedly finding the absence of
    rational factual or legal bases to support the Arizona Seldins’
    theories of modifying or vacating the final award. We hold that
    the district court did not abuse its discretion in awarding attor-
    ney fees and costs under § 25-824.
    We also reject Scott’s claim that the district court abused
    its discretion in overruling his motion to alter or amend the
    district court’s order and judgment. Scott argues that his argu-
    ments were not ridiculous and that the applications regarding
    the interim awards “were filed only in an ‘abundance of cau-
    tion’ and sought an ‘immediate stay’ to minimize any action by
    the parties or the district court.”55

    In support of his argument, Scott first cites In re Chevron
    U.S.A., Inc.,56 in which the Texas Court of Appeals held that an
    arbitrator’s interim awards were sufficiently final for purposes
    of confirmation and vacation. The district court specifically
    rejected this argument in its February 28, 2019, order. The
    district court noted that In re Chevron U.S.A., Inc. lacked evi-
    dence demonstrating that the parties or arbitration panel had
    agreed or intended the interim decision to be nonfinal and non-
    appealable. The district court also recognized that the Arizona
    Seldins had “not cited to a case where an interim award that
    both the parties and the Arbitrator intended to be non-final was
    treated as a final, appealable arbitration award.”
    Scott also cites American Intl. Specialty Lines Ins. Co. v.
    Allied Capital Corp.57 However, that case is clearly distin-
    guishable from the facts presented here as the parties had
    specifically requested that the arbitration panel make a final
    determination on one of the issues.
    We hold that the district court did not abuse its discretion in
    finding Scott’s interim applications to be frivolous and order-
    ing sanctions accordingly.
    (e) Evidence of Omaha Seldins’ Claims
    in Arizona State Court
    In their fifth assignment of error, the Arizona Seldins argue

    award by currently seeking additional damages in other litiga-
    tion for the same Sky Financial investment.

    An appeal is taken by filing a notice of appeal and depositing the
    required docket fee with the clerk of the district court.59
    The Arizona Seldins filed their notice of appeal in these
    cases on March 27, 2019. On July 5, the Arizona Seldins filed
    a motion in the district court seeking to supplement the bill of
    exceptions and/or to reopen the record. The Arizona Seldins
    claimed that after the arbitration award had been confirmed,
    the Omaha Seldins filed a complaint in an Arizona state court
    alleging the same or similar claims regarding Sky Financial
    that had been arbitrated in these cases. The Arizona Seldins
    sought to supplement the record with evidence of the newly
    filed Arizona cases for purposes of this appeal. The district
    court overruled the motion on the ground that perfection of
    an appeal deprives the trial court of any power to amend or
    modify the record as to matters of substance.
    We hold that the district court did not err when overruling
    the motion to supplement the record. Because the Arizona
    Seldins had perfected their appeal prior to the filing of the
    motion, the district court did not have jurisdiction to supple-
    ment the record with evidence of the Omaha Seldins’ purported
    filings. The Arizona Seldins’ fifth assignment of error is with-
    out merit.
    (f) Description of “Respondents”
    Scott individually asserts on cross-appeal that the district
    court erred in failing to modify or correct an evident material
    mistake in the description of “Respondents” in the final award
    relating to Scott. Scott argues that the parties agreed Scott had
    not personally violated any securities laws and, therefore, he
    cannot be jointly and severally liable on the Sky Financial
    award.
    In the Arizona Seldins’ motion to modify or vacate the
    arbitration award, Scott individually asserted that the arbitra-
    tor had made a material mistake in the final award relating to
    the description of “Respondents.” In its May 3, 2019, order
    59
    See Neb. Rev. Stat. § 25-1912 (Cum. Supp. 2018).

    305 Neb. 185
    overruling the motion, the district court found the final award
    had properly provided that Scott was jointly and severally
    liable for all damages awarded. Classifying Scott’s argument
    as misleading, the district court recognized that although the
    parties agreed Scott had not violated any securities laws, he
    usurped corporate opportunities relating to Sky Financial. The
    district court also noted that Scott’s liability was not based
    on common-law principles of joint and several liability, but
    on his contractual liability as set forth in the parties’ separa-
    tion agreement.
    Scott attempts to invoke § 11(a) of the FAA, which permits
    a court to modify or correct an award “[w]here there was an
    evident material miscalculation of figures or an evident mate-
    rial mistake in the description of any person, thing, or property
    referred to in the award.”
    [23,24] Under the FAA, “arbitration is a matter of contract,
    and courts must enforce arbitration contracts according to their
    terms.”60 “An evident material mistake is an error that is appar-
    ent on the face of the record and would have been corrected
    had the arbitrator known at the time.”61
    In the present case, the definition of which individuals and
    entities comprised each party was set forth in the separation
    agreement and in the first case management order. Throughout
    the arbitration proceedings, the individuals and entities com-
    prising the Omaha Seldins and the Arizona Seldins agreed to
    joint and several liability for any award entered against the
    Omaha Seldins or the Arizona Seldins, respectively.
    Scott entered into a binding agreement to arbitrate all claims
    relating to the separation of the parties’ jointly owned proper-
    ties, and he is included in the definition as one of the individ­
    uals comprising the Arizona Seldins. Scott also agreed to
    joint and several liability for all awards issued against the

    Arizona Seldins. According to the terms of the separation
    agreement, Scott is jointly and severally liable for all awards

    Scott’s motion.
    (g) Claims Bar Date
    Scott individually asserts that the district court erred in
    failing to vacate the final award relating to the Sky Financial
    claim because the claim was untimely and the arbitrator
    exceeded his powers by permitting the Omaha Seldins to bring
    the claim.
    Again, §§ 10 and 11 of the FAA set forth the exclu-
    sive grounds for vacating or modifying an arbitration award.62
    “‘[S]o long as the arbitrator is even arguably construing or
    applying the contract and acting within the scope of his author-
    ity,’ the award should be confirmed.”63
    The separation agreement contains a provision stating that
    “reasonable amendments to Claims in pending actions shall
    be allowed in the Mediator’s discretion based on discovery,
    admissions, interim decision, and other developments in the
    prosecution of the Claim, consistent with the Federal Rules of
    Civil Procedure.” On December 3, 2013, the arbitrator granted
    the Omaha Seldins leave to amend their claims on or before
    December 6, “in the interests of justice and economy.”
    Scott complains that the parties’ agreed-upon claims bar date
    was July 2, 2012, and that the Omaha Seldins’ Sky Financial
    claim was untimely because it was filed on November 14,
    2014. Scott argues that the arbitrator exceeded his powers by
    granting leave to amend because under Fed. R. Civ. P. 15, he
    was required to apply the relation-back doctrine when assess-
    ing the timeliness of the claim.
    Rejecting this argument, the district court found that the arbi-
    trator interpreted the separation agreement when concluding

    leave to amend should be granted and that the arbitrator’s deci-
    sion was consistent with Fed. R. Civ. P. 15(a)(2). That section
    provides that “[t]he court should freely give leave [to amend]
    when justice so requires.”64 The district court also found that
    this argument mischaracterized the significance of “relation
    back” under Fed. R. Civ. P. 15 because the amended plead-
    ing did relate back to a claim that had originally been filed on
    October 9, 2011, prior to the parties’ claims bar date.
    We hold that the district court did not err in rejecting this
    claim. Scott does not argue that the arbitrator was not interpret-
    ing the separation agreement; rather, he argues that the arbitra-
    tor “was required to apply the ‘relation-back’ method of review
    under the [Federal Rules of Civil Procedure], before allowing
    the Sky Financial Claim to be brought after the Claims Bar
    Date.”65 The record clearly demonstrates the arbitrator was
    construing the separation agreement when he concluded that
    leave should be granted. The arbitrator’s decision to grant the
    leave is not grounds to vacate the award. This argument is
    without merit.
    4. Omaha Seldins’ Cross-Appeal
    On cross-appeal, the Omaha Seldins argue they are enti-
    tled to reasonable attorney fees and costs in the amount of
    $342,860.95. Alternatively, the Omaha Seldins seek a determi-
    nation that the district court erred in denying their motion for
    order nunc pro tunc.
    In determining the amount of a cost or attorney fee award
    under § 25-824(2), Neb. Rev. Stat. § 25-824.01 (Reissue 2016)
    states that “the court shall exercise its sound discretion.”
    In its May 3, 2018, order, the district court entered judg-
    ment in favor of the Omaha Seldins for an amount equal
    to the attorney fees and costs incurred in resisting the
    Arizona Seldins’ application seeking vacation or modifica-
    tion of the final award and in seeking dismissal of the various
    64
    Fed. R. Civ. P. 15(a)(2).

    applications filed by Scott. After the judgment was issued,
    the Omaha Seldins submitted evidence demonstrating that
    it had incurred $342,860.95 in fees and costs: $211,676.50
    by the Bryan Cave law firm and $131,184.45 by the McGill
    law firm. However, when calculating the amount of fees to
    be awarded, the district court neglected to include the Bryan
    Cave law firm’s fees of $211,676.50. Although intending to
    include the fees from both law firms, the district court’s order
    included only the McGill law firm’s fees for a total amount
    of $131,184.45.
    The Omaha Seldins filed a motion for order nunc pro tunc,
    seeking an order substituting $342,860.95 for the total amount
    of fees incurred. In a written order, the district court stated that
    it had “clearly intended to award attorney fees to Petitioners in
    an amount, as stated in the Court’s Order of February 28, 2019,
    equal to the attorney fees and costs incurred.” But the court
    denied the motion after concluding that “[a]n Order Nunc Pro
    Tunc [could not] be used to enlarge the judgment or substan-
    tially amend[] the judgment even though said judgment was
    not the order intended.”
    Pursuant to the May 3, 2018, order, the Omaha Seldins are
    entitled to their judgment for “an amount equal to the attor-
    neys’ fees and costs [the Omaha Seldins] incurred in resisting
    [the Arizona Seldins’] application seeking vacation or modifi-
    cation of the Final Award and in seeking dismissal of the vari-
    ous applications [filed by Scott].” The district court’s error in
    calculating the amount of the award resulted in the Omaha
    Seldins’ being unfairly deprived of their right to $211,676.50
    in fees incurred by the Bryan Cave law firm. Thus, the district
    court abused its discretion in determining the overall amount
    of the award.
    [25] Ordinarily, an improper calculation of attorney fees
    would require a remand in order to reconfigure the award.66
    However, when the record is sufficiently developed that a

    reviewing court can apply the law to the facts and calculate a
    fair and reasonable fee without resorting to remand, that route
    is available to the appellate court.67
    Here, a remand is not required because the Omaha Seldins
    presented evidence demonstrating the amount of fees incurred,
    and we find these fees to be reasonable. Further, a remand
    would serve only to needlessly prolong this litigation and
    further undermine the finality of the arbitration award. We
    conclude that the Omaha Seldins are entitled to a total fee
    award of $342,860.95. Accordingly, we order the Arizona
    Seldins to pay the Omaha Seldins an additional $211,676.50
    for fees incurred by the Byran Cave law firm on behalf of the
    Omaha Seldins.
    [26] Because we order the payment of $211,676.50, we do
    not reach or address the issue of whether the district court erred
    in denying the Omaha Seldins’ motion for order nunc pro tunc.
    An appellate court is not obligated to engage in an analysis
    that is not necessary to adjudicate the case and controversy
    before it.68
    5. Arizona Seldins’ Motion
    to Dismiss Cross-Appeal
    The Arizona Seldins, along with Scott and Millard, filed
    a joint motion to dismiss the Omaha Seldins’ cross-appeal
    on the ground that the Omaha Seldins’ registration of the
    district court’s judgment with an Arizona state court consti-
    tuted a voluntary acceptance of the benefits of the judgment
    and, thus, prevents the Omaha Seldins from prosecuting their
    cross-appeal. The Omaha Seldins maintain that they have not
    attempted to collect upon the judgment entered on February 28,
    2019, and that the registration of the judgment was merely a
    procedural act taken for purposes of collecting on the judgment
    when collection was permitted.

    [27-29] Generally, under the acceptance of benefits rule, an
    appellant may not voluntarily accept the benefits of part of a
    judgment in the appellant’s favor and afterward prosecute an
    appeal or error proceeding from the part that is against the
    appellant.69 However, the rule does not apply when the appel-
    lant has conceded to be entitled to the thing he or she has
    accepted and where the appeal relates only to an additional
    claim on his or her part.70 In asserting that the acceptance of
    benefits rule precludes an appeal, the burden is on the party
    asserting the rule to demonstrate that the benefits of the judg-
    ment were accepted.71
    Here, the Omaha Seldins agree with the judgment, except
    for seeking an additional recovery of attorney fees that were
    mistakenly omitted from the district court’s judgment. Further,
    the Arizona Seldins have presented no evidence demonstrat-
    ing the Omaha Seldins have accepted the benefits of the
    judgment. We hold that the Omaha Seldins’ mere registration
    of the judgment does not preclude their cross-appeal for the
    recovery of additional fees and costs. This argument is with-
    out merit.
    VI. CONCLUSION
    The FAA provides that a court must confirm an arbitra-
    tion award unless grounds exist for vacating or modifying the
    award under § 10 or § 11 of the FAA.72 Because neither the
    Arizona Seldins nor Scott have demonstrated any such grounds
    exist, the parties are bound by their agreement to arbitrate and
    the arbitrator’s construction of that agreement.
    We hold that the district court did not err in confirming
    the arbitration award and denying the motions to vacate and/
    or modify the award, nor did it err in denying the Arizona
    69

    Seldins’ motion to supplement the record. We further hold that
    the district court did not abuse its discretion when awarding
    attorney fees in favor of the Omaha Seldins or when deny-
    ing Scott’s motion to alter or amend the court’s May 3, 2018,
    order. We conclude that the Omaha Seldins’ registration of
    the district court’s judgment does not preclude the Omaha
    Seldins’ cross-appeal. Finally, we hold that the Omaha Seldins
    are entitled to reasonable attorney fees and costs incurred in
    confirming the arbitration award and resisting the various
    applications filed by the Arizona Seldins and Scott and that the
    district court abused its discretion when failing to include the
    Bryan Cave law firm’s fees in its calculation of the amount of
    fees to be awarded.
    Accordingly, we (1) affirm the district court’s confirmation
    of the arbitration award, (2) affirm the district court’s denial
    of the Arizona Seldins’ and Scott’s motions to vacate and/or
    modify the award, (3) affirm the district court’s denial of the
    Arizona Seldins’ motion to supplement the record, (4) affirm
    the district court’s award of sanctions under § 25-824, (5) over-
    rule the Arizona Seldins’ motion to dismiss the Omaha Seldins’
    cross-appeal, and (6) sustain the Omaha Seldins’ cross-appeal
    and order the fee judgment in favor of the Omaha Seldins be
    increased to $342,860.95.
