    John J. Bower, appellant and cross-appellee,
    v. Eaton Corporation and Old R epublic
    Insurance Company, appellees
    and cross-appellants.
    ___ N.W.2d ___
    Filed October 12, 2018.   No. S-17-1188.
    1.	 Workers’ Compensation: Appeal and Error. An appellate court is
    obligated in workers’ compensation cases to make its own determina-
    tions as to questions of law.
    2.	____: ____. Determinations by a trial judge of the Workers’
    Compensation Court will not be disturbed on appeal unless they are
    contrary to law or depend on findings of fact that are clearly wrong in
    light of the evidence.
    3.	 Workers’ Compensation. Whether an injured worker is entitled to
    vocational rehabilitation is ordinarily a question of fact to be determined
    by the Workers’ Compensation Court.
    4.	 Workers’ Compensation: Appeal and Error. The percentage of per-
    manent partial loss of use for an injured member is a question of fact
    that an appellate court reviews for clear error.
    5.	 Workers’ Compensation: Expert Witnesses. As the trier of fact, the
    Workers’ Compensation Court is the sole judge of the credibility of the
    witnesses and the weight to be given their testimony.
    6.	 Workers’ Compensation: Rules of Evidence: Due Process. The
    Workers’ Compensation Court is empowered to admit evidence not
    normally admissible under the rules of evidence applicable in the trial
    courts of this state, subject to the limits of constitutional due process.
    7.	 Workers’ Compensation: Evidence. Given the beneficent purposes
    of workers’ compensation law, the Workers’ Compensation Court can
    admit evidence not normally admissible in order to investigate cases in
    the manner it judges is best calculated to ascertain the substantial rights
    of the parties and to carry out justly the spirit of the Nebraska Workers’
    Compensation Act.

    8.	 Workers’ Compensation: Physicians and Surgeons: Words and
    Phrases. Only the supervising physician in a physician-physician assist­
    ant relationship falls under the definition of physician as stated in
    Workers’ Comp. Ct. R. of Proc. 49(O) (2018).
    9.	 Workers’ Compensation: Appeal and Error. Whether an employee’s
    compensable scheduled member injury has resulted in a whole body
    impairment and loss of earning power is a question of fact, which an
    appellate court reviews for clear error.
    10.	 Workers’ Compensation. Employees are not limited to benefits for a
    scheduled member injury when the effects of that injury have extended
    to other parts of the employee’s body in a manner that impairs the
    employee’s ability to work.
    11.	 ____. The test for determining whether a disability is to a scheduled
    member or to the body as a whole is the location of the residual impair-
    ment, not the situs of the injury.
    12.	 Workers’ Compensation: Proof. An employee has the burden to prove
    by a preponderance of the evidence compensability of a claim against an
    employer under the Nebraska Workers’ Compensation Act.
    13.	 Workers’ Compensation. A workers’ compensation award cannot be
    based on mere possibility or speculation.
    14.	 Workers’ Compensation: Evidence. An award of future medical
    expenses requires explicit evidence that future medical treatment is rea-
    sonably necessary to relieve the injured worker from the effects of the
    work-related injury.
    15.	 Appeal and Error. An appellate court will not consider an issue on
    appeal that was not presented to or passed upon by the trial court.
    16.	 Workers’ Compensation. The Nebraska Workers’ Compensation Act is
    construed liberally to carry out its spirit and beneficent purposes.
    17.	 Workers’ Compensation: Jurisdiction: Statutes. As a statutorily cre-
    ated court, the Workers’ Compensation Court is a tribunal of limited and
    special jurisdiction and has only such authority as has been conferred on
    it by statute.
    18.	 Workers’ Compensation: Jurisdiction: Contracts: Parties: Insurance.
    The Nebraska Workers’ Compensation Act does not afford the compen-
    sation court jurisdiction to resolve contractual disputes between employ-
    ees and third-party insurers.
    19.	 Workers’ Compensation: Jurisdiction: Contracts: Insurance. A con-
    tractual dispute over private agreements for disability coverage that is
    not workers’ compensation coverage is not ancillary to the compensation
    court’s primary jurisdiction.
    20.	 Workers’ Compensation: Jurisdiction: Termination of Employment.
    Wrongful discharge in relation to filing a workers’ compensation claim
    - 313 -

    does not fall under the compensation court’s exclusive jurisdiction over
    accidents arising out of and in the course of employment.
    21.	   Workers’ Compensation: Termination of Employment: Torts.
    Wrongful discharge is not one of the tort actions for which employers
    receive relief in exchange for liability under the Nebraska Workers’
    Compensation Act.
    22.	   Workers’ Compensation: Penalties and Forfeitures. To avoid the
    penalty provided for in Neb. Rev. Stat. § 48-125 (Cum. Supp. 2016),
    an employer need not prevail in the employee’s claim, but must have
    an actual basis in law or fact for disputing the claim and refusing
    compensation.
    23.	   Workers’ Compensation: Penalties and Forfeitures: Time: Appeal
    and Error. An appellate court reviews for clear error the compensation
    court’s findings concerning reasonable controversy underlying its deter-
    mination of waiting-time penalties.
    24.	   Workers’ Compensation: Proof. Depending on the circumstances, a
    reasonable controversy may exist regarding the employer’s liability until
    an employee presents the employer with competent medical evidence
    that he or she is entitled to workers’ compensation benefits.
    25.	   Attorney Fees. The determination of the amount of attorney fees is
    necessarily a question of fact that requires a factual determination on
    several factors, including the value of legal services rendered by an
    attorney by considering the amount involved, the nature of the litigation,
    the time and labor required, the novelty and difficulty of the questions
    raised, the skill required to properly conduct the case, the responsibil-
    ity assumed, the care and diligence exhibited, the result of the suit, the
    character and standing of the attorney, and the customary charges of the
    bar for similar services.

    NATURE OF CASE
    The employee appeals from an award of the Nebraska
    Workers’ Compensation Court. The issues presented concern
    the employee’s member impairment rating, whether an injured
    extremity caused a whole body impairment, the sufficiency
    of the evidence to prove out-of-pocket medical expenses and
    future medical expenses, whether a physician assistant is a
    “physician” for the purpose of admitting signed written reports
    in lieu of testimony, whether there was no reasonable contro-
    versy as to the compensability of the injury such that greater
    waiting-time penalties should have been imposed, the compen-
    sation court’s jurisdiction to decide retaliatory discharge or a
    private disability insurer’s right to reimbursement, the neces-
    sity of vocational rehabilitation, and the amount of attorney
    fees. We affirm.
    BACKGROUND
    John J. Bower worked for Eaton Corporation (Eaton) as a
    relief operator. Bower earned approximately $19 per hour and
    worked approximately 56 hours per week. On September 30,
    2013, Bower injured his right shoulder in an accident arising
    out of and in the course of his employment.
    Bower reported the incident to his supervisor that same day,
    but continued working until the end of his shift. Bower woke
    up the following morning with “the sharpest pain I’ve ever . . .
    felt before.” He saw his general physician, Dr. Chadd Murray.
    An x ray did not reveal an injury.
    When nonsurgical treatments did not alleviate continuing
    symptoms, Bower was referred to Dr. Heber Crockett, an
    orthopedic surgeon, for treatment of his injury. Magnetic reso-
    nance imaging on November 25, 2013, revealed a moderate
    partial rotator cuff tear.
    Over the course of the next 3 years, the injury was treated
    with medication, steroid injections, physical therapy, and four
    surgical procedures. The surgical procedures were performed
    - 315 -

    on February 4 and May 20, 2014, and March 17 and December
    22, 2015. During this time, Eaton did not acknowledge that the
    injury was work related and did not pay workers’ compensa-
    tion benefits.
    Bower filed a workers’ compensation claim on February
    24, 2015. Bower reached maximum medical improvement on
    June 6, 2016, during the pendency of the workers’ compen-
    sation proceedings. He submitted to an independent medical
    examination on July 7, conducted by Dr. Michael Morrison, an
    orthopedic surgeon.
    Morrison opined that Bower suffered from a permanent
    12-percent impairment of his right upper extremity as a result
    of the September 2013 injury. After receiving Morrison’s
    report, Eaton determined that Bower had incurred a work-
    related injury on September 30, 2013. Eaton determined that
    the February and May 2014 and March 2015 surgical pro-
    cedures were compensable. But Eaton determined that the
    December 2015 surgery was not compensable.
    On August 12, 2016, Eaton paid Bower temporary total dis-
    ability benefits representing the periods from February 4 until
    July 17, 2014, and March 17 until August 16, 2015, in a total
    amount of $33,073.72. Eaton also paid on August 12, 2016,
    $19,718.91 in permanent partial disability benefits based on
    Morrison’s assessment of a 12-percent permanent impairment
    of Bower’s right upper extremity.
    On September 1, 2016, Eaton discharged Bower from his
    employment, explaining to Bower that Eaton could not accom-
    modate the work restrictions for his injury. Bower had been
    performing his regular duties without any accommodations,
    believing that he was adequately compensating with his left
    arm in order to avoid lifting too much weight with his right.
    Moreover, Bower believed he was qualified to continue work-
    ing at Eaton in different positions as the “lead” or supervisor
    of the line. Nevertheless, representatives of Eaton told him
    that he was not working within his restrictions and that he

    301 Neb. 311
    would be discharged unless he could convince a physician to
    reduce them.
    In his petition, Bower had sought temporary total disabil-
    ity benefits, vocational rehabilitation, and payment of medi-
    cal bills incurred and to be incurred in the future, as well as
    waiting-time penalties and attorney fees. In a joint pretrial
    memorandum, the parties presented several issues for deter-
    mination, including reimbursement for out-of-pocket medical
    expenses and entitlement to future medical expenses, entitle-
    ment to return to work at Eaton or vocational rehabilitation
    services, the amount of Bower’s permanency rating to his
    right upper extremity and whether he suffered a whole body
    impairment, Eaton’s insurer’s entitlement to repayment for
    short-term disability payments made to Bower in relation to his
    injury, Bower’s entitlement to attorney fees and a waiting-time
    penalty, and whether Bower was entitled to compensation for
    allegedly being discharged in retaliation for Eaton’s payment
    of workers’ compensation benefits.
    The statement of issues for determination in the joint pre-
    trial memorandum did not include reimbursement for vacation
    time used during treatment of the September 2013 injury. In
    the court’s notice of trial and pretrial order, it had advised the
    parties that any issue not set forth in the joint pretrial memo-
    randum would be deemed waived.
    The court issued its award on October 16, 2017, following
    a trial.
    Temporary Total
    Disability Awarded
    In the court’s award, it found that all the surgeries were
    compensable. Thus, in addition to the amount paid voluntarily
    by Eaton during the pendency of the proceedings, the court
    awarded temporary total disability benefits pertaining to the
    December 2015 surgery. This amounted to a total of $1,877.99,
    which neither party disputes on appeal.

    Permanent Disability Based on
    Member Impairment R ating
    of 12 Percent
    The court awarded permanent disability benefits based on
    a 12-percent impairment to Bower’s right upper extremity.
    This member impairment rating was derived from Morrison’s
    report.
    Bower had submitted a report by Crockett’s physician
    assist­
    ant, Yuji Kitabatake. Kitabatake opined in the report
    that Bower suffered a 15-percent permanent impairment to his
    right upper extremity. The report was signed “Yuji Kitabatake,
    PA-C for Heber C. Crockett, M.D.” Crockett did not sign the
    document. Eaton objected to the report as hearsay and outside
    the scope of Workers’ Comp. Ct. R. of Proc. 10 (2018). The
    court received the report into evidence, but stated it would
    give the report whatever weight it found was due after review-
    ing it.
    In its award, the court concluded that the report was not
    due any weight. Citing to Neb. Rev. Stat. § 48-151(1) (Reissue
    2010) and Workers’ Compensation Court rule 10, the court
    found that the report failed to qualify as an expert medical
    opinion upon which it could rely for a determination of work-
    ers’ compensation benefits.
    No Whole Body Impairment
    The court declined Bower’s suggestion that his permanent
    disability benefits should be calculated based upon a loss of
    earning capacity under an impairment to the body as a whole.
    The only evidence of an impairment to the body as a whole
    was Kitabatake’s report which stated, “Conversion from upper
    extremity to whole person is from 15% to 9% of whole person
    . . . .” Kitabatake did not otherwise describe how the shoulder
    injury caused a whole body impairment.
    In refusing to calculate the permanent partial disability
    award based on impairment to the body as a whole, the court
    reasoned that the medical evidence showed Bower’s residual
    - 318 -

    301 Neb. 311
    limitation and impairment were to his right upper extremity,
    and the court was “not persuaded that [Bower’s] impairment to
    his right upper extremity has in some manner manifested itself
    as a . . . whole [body] impairment.”
    Partial Waiting-Time
    Penalty Awarded
    The court awarded Bower a waiting-time penalty pursuant
    to Neb. Rev. Stat. § 48-125(3) (Cum. Supp. 2016), but only in
    relation to Eaton’s failure to timely pay workers’ compensa-
    tion benefits for the December 2015 surgery and corresponding
    recovery period. The waiting-time penalty for such benefits
    was $939. The court found that there was no longer a reason-
    able controversy as to the compensability of Bower’s injury
    and the resulting medical care, including the December 2015
    surgery and recovery period, as of the date of Eaton’s receipt
    of Morrison’s report.
    The court declined to award additional waiting-time penal-
    ties in relation to the remaining benefits that were paid by
    Eaton voluntarily on August 12, 2016, because it concluded
    that a reasonable controversy existed as to the compensability
    of Bower’s injury until Eaton received Morrison’s report. The
    court explained that the reasonable controversy stemmed from
    Murray’s original progress note. The note described that Bower
    was seen on October 1, 2013, complaining of shoulder pain.
    And, in the “History of Present Illness” section, under the title,
    “Recent Interventions,” Murry wrote, “He has no injury to his
    shoulder just woke up with the pain.”
    When an agent of Eaton advised Bower that Murray had
    failed to indicate the injury was work related, Murray revised
    the progress note. The revision was apparently faxed to Eaton
    on November 22, 2013. It added that Bower “had injured his
    shoulder at work when he was lifting a heavy item, he has had
    pain but it became much worse this morning.” However, the
    amended note continued to include the contradictory language
    from the original progress note.

    Exhibit 48 reflects that Eaton’s workers’ compensation
    insurer sent a letter to Murray on December 10, 2013, request-
    ing that Murray explain the discrepancies between the initial
    report and the revised report and why it was changed. The
    letter stated that Eaton’s workers’ compensation insurer had
    attempted to speak with Murray on several occasions to discuss
    the discrepancy. There was no evidence that Murray responded
    to Eaton’s inquiries.
    No Out- of-Pocket Medical
    Expenses Awarded
    The court denied Bower’s claim for unpaid out-of-pocket
    medical expenses. In its pretrial order, the court had ordered
    the parties to file a joint pretrial memorandum, including,
    among other things, a “medical expense cover sheet setting
    forth an itemization of each medical expense incurred and
    unpaid, or for which reimbursement is claimed, by provider,
    date, and amount.”
    The parties jointly submitted a medical expense cover sheet
    that specified providers and amounts, but not dates. It showed
    a total paid by Bower in the amount of $3,975.41 and a total
    paid by Bower’s insurer in the amount of $38,735.88. The
    cover sheet showed a total amount of medical expenses, by
    provider, of $104,356.87.
    At trial, Bower entered into evidence voluminous medical
    billing statements and records. The medical billing statements
    are contained in exhibits 23 through 32, and the medical
    records are found in exhibits 16 through 20. The billing state-
    ments show numerous payments made by health care insurance
    and by patient, but several statements contain overlapping
    dates, and thus duplicative payment receipts.
    The court additionally accepted into evidence exhibits 14
    and 15, which contain Bower’s summarization of his out-of-
    pocket expenses. Most, but not all, of the items summarized
    are detailed by date and provider. Exhibits 14 and 15 claimed a
    total of $12,315.94 in out-of-pocket expenses. Bower testified

    BOWER v. EATON CORP.
    Cite as 
    301 Neb. 311
    that he was never reimbursed for any out-of-pocket expenses
    he paid during the treatment of his injury.
    After trial, the court contacted counsel and requested addi-
    tional information to clarify the medical expenses. Counsel
    were to submit the information by stipulation on October 6,
    2017. Counsel did not provide the information as requested.
    Approximately 2 weeks later, the court again contacted counsel
    on October 10, requesting additional information. Counsel indi-
    cated they would have the information to the court by October
    12; but counsel did not provide any additional information.
    In denying compensation for any out-of-pocket medical
    expenses, the court explained, “The medical expense informa-
    tion provided by the parties falls woefully short of what was
    ordered to be provided by the Pretrial Order, and the Court is
    unable to meaningfully analyze the information.” Specifically,
    the court noted that the cover sheet reflected medical expenses
    still owed in an amount of $61,645.58, which amount the court
    observed was not reflected in the exhibits entered into evi-
    dence. Furthermore, the court noted the discrepancy between
    the claimed amount of out-of-pocket medical expenses in
    exhibits 14 and 15 of $12,315.94 and the amount of $3,975.41
    stated as being paid by Bower in the medical expenses cover
    sheet of the joint pretrial memorandum.
    The court concluded that Bower had “failed to satisfy his
    burden to prove that the medical expenses submitted in Exhibits
    14, 15, and 23 through 32, are fair, reasonable, and related to
    the work injury.” With this reasoning, the court awarded Bower
    no out-of-pocket medical expenses.
    Attorney Fees Awarded
    Because the court had determined that Eaton failed to timely
    pay benefits relating to the December 2015 surgery, the court
    awarded attorney fees under § 48-125(2)(a), in the amount of
    $7,500. The court explained that it had reached the amount of
    attorney fees to be awarded based upon the general nature of
    the case, the time spent in preparing and trying the case, the
    - 321 -

    301 Nebraska R eports
    BOWER v. EATON CORP.
    Cite as 
    301 Neb. 311
    novelty and difficulty of the questions raised, the skill required
    to properly conduct the case, the responsibility assumed, the
    care and diligence exhibited, the result of the suit, the charac-
    ter and standing of the attorney, and the customary charges of
    the bar for similar services.
    No Future Medical
    Expenses Awarded
    The court did not award future medical expenses. The court
    found that Bower had failed to establish by explicit medi-
    cal testimony that future medical care would be reasonably
    necessary.
    Bower had testified at trial that Crockett told him he might
    need additional cortisone injections if his pain increased;
    Crockett did not testify. The only other evidence submitted by
    Bower as to future medical treatment was Kitabatake’s report,
    in which Kitabatake opined that “it is a reasonable degree of
    medical certainty that [Bower] may need injections and physi-
    cal therapy in the future.”
    In contrast, Morrison opined in his report that “no other
    treatment is necessary other than a home program of passive
    stretching and shoulder girdle strengthening that could be car-
    ried out on a self-motivated program.”
    In denying an award of future medical expenses, the court
    reiterated that Kitabatake’s opinions lacked foundation and
    were accordingly insufficient to support an award of benefits.
    Additionally, the court reasoned that Kitabatake’s statement
    that Bower “may” need additional care lacked sufficient cer-
    tainty to be considered explicit medical evidence of the neces-
    sity of future medical care.
    Vocational R ehabilitation
    Services Awarded
    The court concluded that Bower was entitled to vocational
    rehabilitation services and temporary total disability benefits
    during the time that Bower participates in an approved voca-
    tional rehabilitation plan.
    - 322 -

    301 Nebraska R eports
    BOWER v. EATON CORP.
    Cite as 
    301 Neb. 311
    The court had appointed a vocational rehabilitation coun-
    selor. The stipulation of facts in the joint pretrial memorandum
    stated, “[Bower] has been referred to a vocational rehabilitation
    expert through the Worker[s’] Compensation Court system.”
    The counselor submitted four reports between February
    and August 2017. The reports indicate that the counselor had
    attempted to find suitable employment for Bower with Eaton,
    but was unsuccessful. The counselor’s labor market research
    indicated that if Bower returned to the labor market with his
    current qualifications, he could expect to obtain employment
    earning approximately 60 percent of the hourly wage he earned
    at Eaton, or approximately $12 per hour.
    With the approval of the court, the counselor subsequently
    conducted a vocational evaluation. Based on the evaluation,
    the counselor recommended moving forward with developing a
    vocational rehabilitation plan.
    The court found that Bower had met his burden to show he
    is entitled to vocational rehabilitation services. Referring to
    the stipulation of facts in the joint pretrial memorandum, the
    court reasoned, first, that “[t]he parties stipulated that [Bower]
    is entitled to vocational rehabilitation services and a counselor
    has been appointed by the Court to perform these services.”
    Second, the court noted that there was medical evidence in
    the record that Bower was unable to return to work at Eaton
    after the December 2015 surgery, because Eaton was unable to
    accommodate the permanent work restrictions set forth by the
    functional capacity examination.
    No Jurisdiction Over Short- and
    Long-Term Disability Payments
    The court declined the parties’ invitation to address whether
    Bower was liable to Eaton’s private insurer for disability
    payments made in relation to Bower’s injury. Bower had
    submitted into evidence demands by Eaton’s insurance pro-
    vider that Bower repay approximately $16,000 in short-term
    disability payments made by the insurer while Eaton refused

    workers’ compensation benefits. The short-term disability
    insurance plan, signed by Bower, provided that Bower would
    reimburse the insurer to the extent that benefits paid should
    be offset by reason of benefits received under any work-
    ers’ compensation law. The court explained that this issue
    involved contract questions outside the jurisdictional scope of
    the Nebraska Workers’ Compensation Act and the Workers’
    Compensation Court.
    No Jurisdiction Over
    Wrongful Termination
    Likewise, the court determined that it lacked jurisdiction
    to consider Bower’s wrongful discharge allegations. Bower
    testified that he did not think Eaton had grounds to discharge
    him, because he believed he could perform his duties within
    the medical restrictions he had been given. The court con-
    cluded that any claim for retaliatory discharge is outside the
    framework of the Nebraska Workers’ Compensation Act. Thus,
    Bower’s potential remedy for the alleged retaliatory discharge
    must be brought in a different forum.
    R eimbursement for Vacation Time
    The court’s award did not address any claim for compen-
    sation of vacation time used during periods Bower could not
    work because of the September 2013 injury. This was presum-
    ably because Bower did not include this issue in the pretrial
    statement of issues for determination.
    ASSIGNMENTS OF ERROR
    Bower assigns that the Workers’ Compensation Court erred
    by failing to (1) award permanent disability based on a loss
    of earning capacity rather than a member impairment rating,
    (2) award permanent disability based on a 12-percent member
    impairment rating rather than a 15-percent member impair-
    ment rating, (3) award a waiting-time penalty from the date
    of the injury rather than the date of payment of benefits in
    August 2016, (4) award Bower out-of-pocket medical expenses

    pursuant to the exhibits offered at trial, (5) award future medi-
    cal expenses for cortisone injections, (6) award reimbursement
    of vacation time and short-term disability, (7) decide the issue
    of Eaton’s right to reimbursement of disability payments made
    by its insurer, and (8) decide Bower’s wrongful termina-
    tion claim.
    On cross-appeal, Eaton and its workers’ compensation insur-
    ance carrier, Old Republic Insurance Company (Old Republic),
    assign that the court erred in awarding Bower (1) vocational
    rehabilitation services and (2) $7,500 in attorney fees.
    STANDARD OF REVIEW
    Under Neb. Rev. Stat. § 48-185 (Cum. Supp. 2016), the
    judgment made by the compensation court shall have the same
    force and effect as a jury verdict in a civil case and may be
    modified, reversed, or set aside only upon the grounds that (1)
    the compensation court acted without or in excess of its pow-
    ers; (2) the judgment, order, or award was procured by fraud;
    (3) there is not sufficient competent evidence in the record to
    warrant the making of the order, judgment, or award; or (4) the
    findings of fact by the compensation court do not support the
    order or award.
    [1] An appellate court is obligated in workers’ compensation
    cases to make its own determinations as to questions of law.1
    [2] Determinations by a trial judge of the Workers’
    Compensation Court will not be disturbed on appeal unless
    they are contrary to law or depend on findings of fact that are
    clearly wrong in light of the evidence.2
    [3] Whether an injured worker is entitled to vocational reha-
    bilitation is ordinarily a question of fact to be determined by
    the Workers’ Compensation Court.3

    ANALYSIS
    Bower claims on appeal that the court’s award of a 12-­percent
    impairment was insufficient and that, in any event, he should
    have been awarded permanent partial disability based on an
    injury to his body as a whole. Bower argues, further, that the
    court clearly erred in failing to award him any out-of-pocket
    medical expenses and that it should have awarded a waiting-
    time penalty for all the compensation and medical payments
    unpaid within 30 days of Murray’s revised progress note.
    Finally, Bower asserts that the court should have addressed the
    merits of his retaliatory discharge claim, the employer’s private
    disability insurer’s right to reimbursement for temporary dis-
    ability payments, and Bower’s right to reimbursement of vaca-
    tion time used as a result of his injury. On cross-appeal, Eaton
    and Old Republic contest the necessity of vocational rehabilita-
    tion and the amount of attorney fees awarded. We address each
    of these arguments in turn.
    Member Impairment R ating
    [4] We first address Bower’s contention that the court should
    have given his scheduled member impairment a rating of 15
    percent rather than 12 percent. The percentage of permanent
    partial loss of use for an injured member is a question of fact
    that we review for clear error.4
    [5] Impairment to a scheduled member is measured on the
    basis of loss of physical function.5 An impairment rating is
    simply a medical assessment of what physical abilities have
    been adversely affected or lost by an injury.6 The extent of loss

    of use does not necessarily equal the extent of medical impair-
    ment, and testimony need not establish a specific percentage
    impairment rating to be legally sufficient.7 Furthermore, the
    trial judge is not limited to expert testimony to determine the
    degree of disability, but instead may rely on the testimony
    of the claimant.8 Nonetheless, the medical impairment rating
    given by a doctor may be an important factor.9 And, as the trier
    of fact, the Workers’ Compensation Court is the sole judge
    of the credibility of the witnesses and the weight to be given
    their testimony.10
    Kitabatake’s report was the only express medical opinion
    that Bower suffered from a 15-percent impairment to his right
    upper extremity. Bower asserts that the court erred as a matter
    of law in deciding not to give Kitabatake’s report weight on the
    ground that it failed to comply with Workers’ Compensation
    Court rule 10. We find no merit to this argument.
    [6,7] The compensation court does not have the right to
    establish rules of evidence, procedure, or discovery that are
    more restrictive or onerous than the rules applicable to the
    trial courts in this state.11 But it is empowered to admit evi-
    dence not normally admissible under the rules of evidence
    applicable in the trial courts of this state, subject to the limits
    of constitutional due process.12 This is because the Workers’
    Compensation Court is not bound by the usual common-law
    or statutory rules of evidence.13 Given the beneficent pur-
    poses of workers’ compensation law, the court can admit such

    evidence in order to investigate cases in the manner it judges
    is best calculated to ascertain the substantial rights of the par-
    ties and to carry out justly the spirit of the Nebraska Workers’
    Compensation Act.14
    Rule 10 is an evidentiary rule that we have held is not more
    restrictive than the rules applied to trial courts in this state.15
    Rather, rule 10 allows the compensation court to admit into
    evidence medical reports that would not normally be admis-
    sible in the trial courts of this state.16 Rule 10 states in rel-
    evant part:
    A. Medical and Vocational Rehabilitation. . . . [W]ith
    respect to medical evidence on hearings before a judge of
    [the Workers’ Compensation C]ourt, written reports by
    a physician or surgeon duly signed by him, her or them
    and itemized bills may, at the discretion of the court, be
    received in evidence in lieu of or in addition to the per-
    sonal testimony of such physician or surgeon; with respect
    to evidence produced by vocational rehabilitation experts,
    physical therapists, and psychologists on hearings before
    a judge of said court, written reports by a vocational reha-
    bilitation expert, physical therapist, or psychologist duly
    signed by him, her or them and itemized bills may, at the
    discretion of the court, be received in evidence in lieu of
    or in addition to the personal testimony of such vocational
    rehabilitation expert, physical therapist, or psychologist.
    The only requirements for a medical report to be admissible
    under rule 10 are that the report be a medical report and be
    signed by the physician, surgeon, vocational rehabilitation
    expert, physical therapist, or psychologist.17 Physician assist­
    ants are not listed in rule 10.

    The court concluded that Kitabatake’s signature did not sat-
    isfy the requirements of rule 10, because Kitabatake is not a
    “physician.” We agree.
    “Physician” is defined by Workers’ Comp. Ct. R. of Proc.
    49(O) (2018) as “any person licensed to practice medicine
    and surgery, osteopathic medicine, chiropractic, podiatry, or
    dentistry in the State of Nebraska or in the state in which
    the physician is practicing.” Other statutes make clear that
    it is the supervising physician, not the physician assistant,
    who has the license to practice medicine. The Medicine and
    Surgery Practice Act,18 under § 38-2047, specifies that physi-
    cian assistants are considered agents of a supervising physician
    to perform activities delegated by the supervising physician.
    Under § 38-2050(1)(a), to be a supervising physician of a
    physician assistant, a person must “[b]e licensed to practice
    medicine and surgery under the Uniform Credentialing Act.”
    Finally, in the context of the Interstate Medical Licensure
    Compact,19 the Legislature has defined the practice of medi-
    cine as clinical prevention, diagnosis, or treatment of human
    disease, injury, or condition requiring a “physician” to obtain
    and maintain a license in compliance with the Medicine and
    Surgery Practice Act.
    [8] As such, only the supervising physician in a
    ­physician-physician assistant relationship falls under the defi-
    nition of physician as stated in Workers’ Compensation Court
    rule 49(O). Kitabatake’s report, signed only by Kitabatake, was
    not signed by a physician as required by rule 10.
    We have upheld the compensation court’s decision to exclude
    evidence that fails to strictly comply with rule 10. In Johnson
    v. Ford New Holland,20 for example, we held that the court
    18

    did not abuse its discretion in refusing to admit into evidence
    a physician’s written report that failed to comply with rule 10
    because it lacked a signature.
    Similarly here, the court did not abuse its discretion in refus-
    ing to admit into evidence a report that was not signed by a
    physician, as is required by the relevant provisions of rule 10.
    The court’s conclusion that Bower suffered from a 12-percent
    impairment to his right upper extremity was supported by
    Morrison’s report and was not the result of erroneously fail-
    ing to consider the written report signed only by Kitabatake,
    a physician assistant. The court did not clearly err in finding a
    permanent partial loss of 12 percent.
    Whole Body Impairment
    [9] We find no merit to Bower’s alternative argument that he
    should have been awarded permanent total disability benefits
    for an injury to his body as a whole, rather than permanent par-
    tial disability benefits for his injury to his right upper extrem-
    ity. Whether an employee’s compensable scheduled member
    injury has resulted in a whole body impairment and loss of
    earning power is a question of fact, which we review for
    clear error.21
    [10] Under Nebraska’s workers’ compensation statutes, an
    injury to the upper extremity constitutes a scheduled member
    injury.22 Permanent total disability benefits are not generally
    available for a single scheduled member injury.23 However,
    employees are not limited to benefits for a scheduled mem-
    ber injury when the effects of that injury have extended to
    other parts of the employee’s body in a manner that impairs
    the employee’s ability to work.24 When a member injury

    results in a whole body impairment, the court should enter an
    award for loss of earning capacity rather than for the mem-
    ber injury.25
    [11] The test for determining whether a disability is to a
    scheduled member or to the body as a whole is the location
    of the residual impairment, not the situs of the injury.26 If, by
    the point of maximum medical improvement, an employee has
    developed a whole body impairment in addition to a sched-
    uled member injury, the question is whether the work-related
    injury proximately caused the whole body impairment.27 For
    instance, we have held that the compensation court did not
    err in finding that a foot injury proximately caused a whole
    body impairment, upon evidence that the resulting change in
    an employee’s gait caused chronic pain in the employee’s hips
    and lower back.28
    But there was no evidence in this case that Bower’s shoul-
    der injury extended to other parts of his body. The only medi-
    cal opinion that Bower suffered a whole body impairment
    was found in Kitabatake’s report, which, as discussed, the
    court refused to give weight. Even in Kitabatake’s report,
    however, there is no evidence that Bower suffered impair-
    ment to other parts of his body. Kitabatake simply reasoned
    that “[c]onversion from upper extremity to whole person is
    from 15% to 9% of whole person . . . .” Bower’s testimony
    and the exhibits admitted at trial likewise failed to demon-
    strate that Bower suffered residual impairment in other parts
    of his body.
    The court did not clearly err in concluding that Bower did
    not have a whole body impairment as a result of the September
    2013 injury.

    Out- of-Pocket Medical Expenses
    Neither did the court clearly err in concluding that Bower
    failed to satisfy his burden of proof to support an award of
    out-of-pocket medical expenses. This determination involved
    findings of fact, which will not be disturbed on appeal unless
    they are clearly wrong in light of the evidence.29
    Neb. Rev. Stat. § 48-120(1)(a) (Cum. Supp. 2016) provides
    that the employer is liable for, among other things, all reason-
    able medical, surgical, and hospital services, and medicines,
    which are required by the nature of the injury and which will
    relieve pain or promote and hasten the employee’s restoration
    to health and employment. Section 48-120(8) states in relevant
    part that the compensation court shall order “reimbursement to
    anyone who has made any payment to the supplier for services
    provided in this section.” It states in full:
    The compensation court shall order the employer to make
    payment directly to the supplier of any services provided
    for in this section or reimbursement to anyone who has
    made any payment to the supplier for services provided
    in this section. No such supplier or payor may be made
    or become a party to any action before the compensa-
    tion court.30
    [12] An employee has the burden to prove by a preponder-
    ance of the evidence compensability of a claim against an
    employer under the Nebraska Workers’ Compensation Act.31
    Where the evidence shows that certain medical and hospital
    expenses have been incurred by an injured employee, a prima
    facie case is made out.32

    Bower presented exhibits 14 and 15, which are a detailed
    summary of $12,315,94 in out-of-pocket medical expenses.
    But, as the court pointed out, that amount is contradicted by
    the joint medical expense cover sheet claiming only $3,975.41
    in out-of-pocket medical expenses. And it is difficult to sur-
    mise what the medical bills established in out-of-pocket medi-
    cal expenses.
    [13] The court twice sought clarification. The record does not
    reflect that the parties jointly or Bower individually attempted
    to provide such clarification. An award cannot be based on
    mere possibility or speculation.33 The court did not clearly err
    in concluding that, based on the self-contradictory evidence
    presented by Bower and the confusing state of the medical bills
    presented, it would be mere speculation to determine a sum
    certain for out-of-pocket medical expenses.
    Future Medical Expenses
    [14] We find no error in the court’s refusal to award future
    medical expenses. Before an order for future medical benefits
    may be entered, there should be a stipulation of the parties or
    evidence in the record to support a determination that future
    medical treatment will be reasonably necessary to relieve the
    injured worker from the effects of the work-related injury or
    occupational disease.34 An award of future medical expenses
    requires explicit evidence that future medical treatment is
    reasonably necessary to relieve the injured worker from the
    effects of the work-related injury.35
    Morrison opined that no other treatment would be necessary
    for the September 2013 injury other than a “self-motivated
    program” of stretching and strengthening. The only evidence to
    the contrary is found in Kitabatake’s report. But, as discussed,

    the court did not err in discounting the opinion expressed
    therein. Thus, the court did not err in failing to award future
    medical expenses.
    R eimbursement for Vacation, Sick,
    Personal, and Holiday Time
    We turn next to Bower’s claims regarding reimbursement
    for vacation, sick, personal, and holiday time used when he
    was unable to work as a result of the 2013 injury. In its award,
    the court did not expressly address whether Bower had a right
    to reimbursement for any vacation, sick, personal, and holiday
    time. But the court had clearly advised the parties in its pretrial
    order that any issue not set forth in the joint pretrial memo-
    randum would be waived. Bower did not set forth in the joint
    pretrial memorandum the issue of compensation for vacation,
    sick, personal, and holiday time. Indeed, this issue was only
    briefly mentioned in opening statements.
    [15] An appellate court will not consider an issue on appeal
    that was not presented to or passed upon by the trial court.36
    Furthermore, we have on numerous occasions affirmed the
    limiting of the issues at trial to those specified in the pretrial
    order.37 We will not reverse the court’s award for failing to
    address an issue that Bower failed to present in the pretrial
    memorandum after the court had advised the parties that the
    issues at trial would be limited to those specified by the par-
    ties in the joint pretrial memorandum. We find no merit to this

    Eaton and Old Republic argue on cross-appeal that there
    was insufficient competent evidence to warrant the court’s
    award of vocational rehabilitation services. Further, Eaton
    disputes the court’s conclusion that Eaton had stipulated that

    Bower was entitled to vocational rehabilitation services. We
    agree that the record fails to demonstrate a stipulation that
    Bower was entitled to vocational rehabilitation. However, we
    find that the court did not clearly err in concluding upon the
    evidence presented that Bower was entitled to vocational
    rehabilitation.
    [16] Whether an injured worker is entitled to vocational
    rehabilitation is ordinarily a question of fact to be determined
    by the compensation court.38 To determine whether findings of
    fact made by the compensation court support an order grant-
    ing or denying vocational rehabilitation benefits, an appellate
    court must consider the findings of fact in light of the statute
    authorizing vocational rehabilitation benefits, Neb. Rev. Stat.
    § 48-162.01 (Reissue 2010). Furthermore, in considering the
    compensation court’s factual findings, we are mindful that the
    Nebraska Workers’ Compensation Act is construed liberally to
    carry out its spirit and beneficent purposes.39
    Section 48-162.01(1) describes that “[o]ne of the primary
    purposes of the Nebraska Workers’ Compensation Act is resto-
    ration of the injured employee to gainful employment” and that
    “[t]o this end the Nebraska Workers’ Compensation Court may
    employ one or more specialists in vocational rehabilitation.”
    Under § 48-162.01(3):
    When as a result of the injury an employee is unable to
    perform suitable work for which he or she has previous
    training or experience, he or she is entitled to such voca-
    tional rehabilitation services, including job placement and
    training, as may be reasonably necessary to restore him or
    her to suitable employment.
    “‘[S]uitable employment’” is “‘employment which is
    compatible with the employee’s pre-injury occupation, age,
    education, and aptitude.’”40 We have affirmed vocational

    rehabilitation services aimed at placing the employee into
    employment paying wages similar to those earned before the
    work-related injury 41 because the statutory goal of suitable
    employment includes a similar earning capacity.42
    The vocational counselor’s reports show that after much
    investigation, the counselor determined Bower could not
    return to his previous job with Eaton, return to his previous
    job with Eaton with modification, or return to employment at
    Eaton with a new job.43 Bower had indicated that he preferred
    to continue working at Eaton, where he earned a wage and
    benefits commensurate with his 20 years of employment at
    the company. But while Bower believed that he could com-
    pensate for his injury and perform his past job within his
    medical restrictions, Eaton was clear that it would not employ
    Bower given the medical restrictions of his permanent par-
    tial disability.
    The counselor’s labor market research demonstrated that
    with Bower’s current qualifications, Bower would not be
    able to obtain employment earning wages commensurate with
    his past wages at Eaton. Thus, the counselor recommended
    vocational rehabilitation so that Bower could obtain suitable
    employment.
    Eaton and Old Republic argue on cross-appeal that voca-
    tional rehabilitation was not necessary in order for Bower to
    obtain suitable employment, because Bower testified that he
    believed himself to be physically capable of doing the same
    or similar jobs at Eaton or with another manufacturer. Eaton
    ignores the part of Bower’s testimony where he explains that
    a job with another manufacturer would not pay as well as a

    job with Eaton. Eaton also ignores the fact that it refused to
    continue to employ Bower. The court did not clearly err in
    finding that vocational rehabilitation was reasonably necessary
    to restore Bower to suitable employment.
    Private Disability Payments
    and Wrongful Discharge
    [17] We find as a matter of law that the compensation court
    did not err in concluding that it lacked jurisdiction to deter-
    mine the merits of Bower’s claims for damages for wrongful
    discharge and for a declaration as to his liability to reimburse
    Eaton’s insurer for private disability payments. As a statutorily
    created court, the Workers’ Compensation Court is a tribunal
    of limited and special jurisdiction and has only such authority
    as has been conferred on it by statute.44 Under Neb. Rev. Stat.
    § 48-152 (Reissue 2010), the Nebraska Workers’ Compensation
    Court has only the “authority to administer and enforce all of
    the provisions of the Nebraska Workers’ Compensation Act,
    and any amendments thereof, except such as are committed to
    the courts of appellate jurisdiction.”
    [18] We have held that the Nebraska Workers’ Compensation
    Act does not afford the compensation court jurisdiction to
    resolve contractual disputes between employees and third-
    party insurers.45 Neb. Rev. Stat. §§ 48-130 and 48-147 (Reissue
    2010) prohibit the compensation court from taking into consid-
    eration when determining workers’ compensation any benefits
    independent of the act paid to the employee.
    Still, Bower asserts that his alleged contractual obligation
    to reimburse Eaton’s insurer for payments under a private
    disability policy is “ancillary” to resolution of his workers’

    compensation claim and within the compensation court’s juris-
    diction pursuant to Neb. Rev. Stat. § 48-161 (Reissue 2010).46
    Section 48-161 provides that the compensation court shall have
    jurisdiction to decide issues that are “ancillary” to resolution of
    the workers’ compensation claim.
    We have held that § 48-161 grants the compensation court
    jurisdiction to resolve contractual disputes concerning cover-
    age by providers of workers’ compensation insurance.47 We
    have never held, however, that § 48-161 confers upon the com-
    pensation court jurisdiction to resolve contractual disputes for
    coverage that is not workers’ compensation coverage. Bower
    seems to acknowledge that questions of contractual obligations
    under private disability insurance contracts would not usually
    be considered ancillary to the compensation court’s primary
    jurisdiction. But he asserts the fact that “the disability provider
    and Eaton are one in the same” 48 is an unusual circumstance
    that makes a difference.
    Bower fails to explain why this would make a difference.
    With the exception of reimbursement of health care insurance
    providers as specifically described in § 48-120(8), provid-
    ers of insurance coverage other than workers’ compensation
    coverage are third-party insurers outside the scope of the
    Nebraska Workers’ Compensation Act. This is true regard-
    less of whether the private insurance coverage was provided
    through the employer as a benefit of employment.
    [19] A contractual dispute over private agreements for dis-
    ability coverage that is not workers’ compensation coverage is
    not ancillary to the compensation court’s primary jurisdiction.
    As stated by §§ 48-130 and 48-147, nothing in the Nebraska
    Workers’ Compensation Act shall affect any existing insurance

    contract for benefits in addition to the compensation provided
    for by the act, and no insurance of the injured employee inde-
    pendent of the act shall be taken into consideration by the
    compensation court. Bower’s contractual obligations toward
    Eaton’s private disability insurer had no bearing on the court’s
    determinations of the compensability of Bower’s injury, the
    amount of the award, or Bower’s ability to receive the award.
    The court did not err in refusing to address Bower’s obligation
    to reimburse Eaton’s private disability insurer under the offset
    provisions of the private insurance contract.
    [20] Likewise, the court did not err in refusing to consider
    Bower’s claim for wrongful discharge. We have recognized
    that an employee can state a claim in district court for wrongful
    discharge in retaliation for filing a claim under the Nebraska
    Workers’ Compensation Act.49 We have never said that the
    compensation court has jurisdiction over such a claim. To the
    contrary, by recognizing such a claim in district court, we have
    implicitly held that wrongful discharge in relation to filing a
    workers’ compensation claim does not fall under the compen-
    sation court’s exclusive jurisdiction over accidents arising out
    of and in the course of employment.50
    [21] The Nebraska Workers’ Compensation Act does not
    describe wrongful discharge, and as a statutorily created court,
    it is the role of the Legislature to determine what acts fall
    within the Workers’ Compensation Court’s exclusive jurisdic-
    tion.51 Wrongful discharge is not one of the tort actions for
    which employers receive relief in exchange for liability under
    the act. The court was correct in concluding that it lacked juris-
    diction over Bower’s wrongful discharge claim.

    Waiting-Time Penalty
    We turn next to the penalties imposed by the court against
    Eaton for its failure to timely pay all amounts of compensa-
    tion due to Bower. Eaton does not contest that it was liable
    for the $939 imposed for its failure to timely pay benefits
    relating to the December 2015 surgery. But Bower argues that
    the waiting-time penalty should have been more, because no
    reasonable controversy existed as to the compensability of his
    injury by November 8, 2013, the date of his initial medical
    visit to Crockett.
    Section 48-125(1)(a) states that all amounts of “compensa-
    tion” payable under the Nebraska Workers’ Compensation Act
    “shall be payable periodically in accordance with the methods
    of payment of wages of the employee at the time of the injury
    or death.” “Compensation” in reference to additional sums for
    waiting time, an attorney fee, and interest, means periodic dis-
    ability or indemnity benefits payable on account of the employ-
    ee’s work-related injury or death.52 Section 48-125(1)(b) pro-
    vides for a 50-percent waiting-time penalty in the event such
    periodic payments are not timely made.
    [22] Although “reasonable controversy” appears nowhere
    in the text of § 48-125, the phrase has been part of our
    waiting-time penalty jurisprudence for more than 90 years,
    and we have presumed that the Legislature acquiesced in
    such determination of the Legislature’s intent because it has
    never amended the Nebraska Workers’ Compensation Act to
    address reasonable controversy.53 Thus, under § 48-125(1)(b),
    an employer must pay a 50-percent waiting-time penalty if (1)
    the employer fails to pay compensation within 30 days of the
    employee’s notice of disability and (2) no reasonable contro-
    versy existed regarding the employee’s claim for benefits.54

    To avoid the penalty provided for in § 48-125, an employer
    need not prevail in the employee’s claim, but must have an
    actual basis in law or fact for disputing the claim and refus-
    ing compensation.55
    [23] Whether a reasonable controversy exists is a question
    of fact.56 Accordingly, we review for clear error the compensa-
    tion court’s findings concerning reasonable controversy under-
    lying its determination of waiting-time penalties.57
    [24] Depending on the circumstances, a reasonable con-
    troversy may exist regarding the employer’s liability until
    an employee presents the employer with competent medical
    evidence that he or she is entitled to workers’ compensation
    benefits.58 Although the total amount of compensation due
    may be in dispute, the employer’s insurer nevertheless has a
    duty to promptly pay that amount which is undisputed, and the
    only legitimate excuse for delay of payment is the existence
    of genuine doubt from a medical or legal standpoint that any
    liability exists.59
    The court found that a reasonable controversy existed at
    the time of the injury and up until Morrison’s report, because
    internally inconsistent and self-contradictory medical reports
    by Murray created genuine doubt from a medical standpoint
    whether Bower had an injury that was incurred at work.
    Murray’s first report on October 1, 2013, stated that Bower had

    “no injury to his shoulder just woke up with pain.” Murray’s
    revised report faxed to Eaton on November 22 did not eliminate
    that statement. Instead, Murray added that Bower “injured his
    shoulder at work when he was lifting a heavy item, he has had
    pain but it became much worse this morning.” The evidence
    indicates that Eaton tried to speak with Murray on multiple
    occasions in order to obtain clarification as to why Murray had
    changed the medical record and why it was inconsistent. There
    is no evidence that Murray responded to these inquiries.
    In reviewing workers’ compensation cases, this court is not
    free to weigh the facts anew; rather, it accords to the findings
    of the compensation court the same force and effect as a jury
    verdict in a civil case.60 Applying these principles, we find that
    the court did not clearly err in finding there was a reasonable
    controversy as to the compensability of Bower’s injury until
    the report of Eaton’s independent medical examiner.
    Attorney Fees
    Lastly, we address attorney fees. Eaton does not contest that
    some assessment of attorney fees was appropriate as part of
    the penalty for its late payment of compensation relating to the
    December 2015 surgery. Rather, in their cross-appeal, Eaton
    and Old Republic assert that the amount of the fees is unrea-
    sonable. Section 48-125(2)(a) provides for a “reasonable attor-
    ney’s fee” when the employer fails to timely pay compensation
    or medical payments.61
    [25] The determination of an award of attorney fees pursu-
    ant to § 48-125 must be calculated on a case-by-case basis.62
    The determination of the amount of attorney fees is necessar-
    ily a question of fact that requires a factual determination on
    several factors, including the value of legal services rendered

    by an attorney by considering the amount involved, the nature
    of the litigation, the time and labor required, the novelty and
    difficulty of the questions raised, the skill required to properly
    conduct the case, the responsibility assumed, the care and dili-
    gence exhibited, the result of the suit, the character and stand-
    ing of the attorney, and the customary charges of the bar for
    similar services.63
    In arguing that the amount of $7,500 was unreasonable,
    Eaton focuses on the small award of $1,877.99 in contested
    temporary total disability benefits and $939 in penalty ben-
    efits. Eaton argues that Bower’s attorney should not be com-
    pensated for that portion of the work attributable to Bower’s
    unsuccessful claims for reimbursement of medical expenses,
    future medical expenses, loss of earning capacity, and wrong-
    ful termination.
    We have said that while particular attention should be
    given to the amount of legal work performed in relation to
    the unpaid compensation and medical bills, the award is not
    necessarily limited to legal work performed in recovering a
    specific, unpaid medical bill or delinquent compensation.64
    Like other questions of fact, the compensation court’s deter-
    mination of reasonable attorney fees pursuant to § 48-125
    will not be disturbed on appeal unless it is clearly wrong in
    light of the evidence.65 The court’s award of $7,500 was not
    clearly wrong.
    CONCLUSION
    For the foregoing reasons, we affirm the court’s award.
