SUR PETITION FOR PANEL REHEARING
The judges who participated in the decision of this Court having considered the petition for rehearing filed by Philips Lighting North America Corporation in the above-entitled case, panel rehearing is hereby GRANTED for the reasons stated. The precedential opinion and judgment filed on April 23, 2009 are hereby VACATED and the attached opinion is filed forthwith.
OPINION OF THE COURT
Colleen Donlin sued Philips Electronics North America Corporation for employment discrimination after it failed to hire her as a full-time employee. The case was tried before a jury and Donlin was awarded $164,850 in compensatory damages. Philips appealed, raising various challenges to liability and damages. Donlin filed a cross-appeal. For the reasons that follow, we will affirm the jury’s finding of liability and remand for further proceedings with regard to damages.
I.
Philips hired Donlin as a temporary warehouse employee at its Mountaintop, Pennsylvania distribution center in May 2002. Because of fluctuations in demand for Philips’s products, the Mountaintop facility occasionally hired temporary employees to fill and prepare orders for shipment. Like many of the temps at the Mountaintop facility, Donlin applied for a full-time position in the plant, but was not hired. After deciding not to hire Donlin as a full-time employee, Philips ended Donlin’s temporary assignment in January 2003, citing a decrease in sales volume.
Donlin sued Philips for gender discrimination and retaliation pursuant to Title VII of the Civil Rights Act of 1964, 42 U.S.C. § 2000e-2, et seq., seeking compensatory and punitive damages. The District Court granted Philips summary judgment on Donlin’s retaliation claim, but her gender *78 discrimination claim proceeded to trial. At the conclusion of Donlin’s case-in-chief, Philips moved for judgment as a matter of law, which the District Court denied. Philips renewed its motion for judgment as a matter of law after putting on its defense. This time, the District Court denied Philips’s motion on liability grounds, but granted Philips judgment on Donlin’s claim for punitive damages.
The case proceeded to the jury on the issue of liability as well as compensatory damages in the form of back pay and front pay. 1 The jury rendered a verdict in Donlin’s favor on liability and recommended $63,050 in back pay and $395,795 in front pay, for a total of $458,845. The jury’s advisory verdict on front pay was based on the premise that Donlin would have worked for 25 more years until retirement.
Following post-verdict briefing, the District Court heeded the advice of the jury on the back-pay issue, but modified its front-pay award by reducing it to account for only 10 years of damages, finding that calculating damages for a 25-year period was too speculative. The final front pay award was $101,800, for a total of $164,850 in compensatory damages.
At the conclusion of the proceedings, Philips filed a motion for judgment notwithstanding the verdict, which the District Court denied. Philips now appeals, asserting errors with regard to liability, damages, and attorney’s fees, and Donlin cross-appeals. We have jurisdiction under 28 U.S.C. § 1291.
II.
We begin with Philips’s contention that the liability verdict cannot stand because the jury instructions were flawed. Specifically, Philips asserts that the District Court mischaracterized its rationale for deciding not to hire Donlin as a permanent employee. Because Philips objected to the jury instructions at trial, we review this claim for abuse of discretion.
Cooper Distrib. Co. v. Amana Refrigeration, Inc.,
In determining liability, the trial court analyzed Donlin’s employment discrimination suit under the familiar burden-shifting framework of
McDonnell Douglas Corp. v. Green,
Philips contends that the District Court’s jury charge distorted step two of the McDonnell Douglas framework by mischaracterizing its nondiscriminatory reasons for choosing not to hire Donlin. The District Court’s instruction to the jury provided, in relevant part:
I instruct you ... that Philips Lighting has given in this case what is generally accepted as a nondiscriminatory reason for its failure to hire Ms. Donlin. They *79 told you that their decision was based on her record of attendance, production, and accuracy as compared to all the other applicants that they considered for the same job. I instruct you, members of the jury, that if you disbelieve Philips’s explanation for its conduct, then you may — you may not, but you may very well find that Ms. Donlin has proved intentional discrimination,
(emphasis added).
Philips zeroes in on the word “accuracy,” claiming that it should not have been included in the instruction because it was not a relevant factor in the company’s hiring decision. Because the instructions did not accurately summarize the company’s reasons for choosing not to hire Donlin, Philips argues, the jury was invited to find that Philips’s rationale for not hiring Donlin was pretextual since Philips never claimed that Donlin was “inaccurate.”
Philips tacitly accuses the District Court of pulling the issue of “accuracy” out of thin air, contending that its witnesses consistently described the company’s hiring factors as only attendance, productivity, and quality of work. This argument is belied by the record. In response to a question regarding which factors were important when hiring a temporary worker for permanent employment, Donlin’s shift supervisor, Duane Wright, agreed that the company considered production, attendance, and accuracy to be of “paramount importance.” Additionally, at various stages of the trial, the jury heard testimony regarding “picking errors,” which occurred when an employee failed to correctly collect products for an order; such errors can fairly be described as involving accuracy.
By taking issue with the District Court’s use of the word “accuracy,” Philips claims reversible error by latching on to one word in a 23-page jury charge. We are not persuaded. We begin by noting that a mistake in a jury instruction constitutes reversible error only if it fails to “fairly and adequately” present the issues in the case without confusing or misleading the jury.
United States v. Ellis,
The trial judge is permitted considerable latitude to summarize and comment upon the evidence, provided that the jury is neither confused nor misled.
Am. Home Assur. Co. v. Sunshine Supermarket, Inc.,
*80 III.
Having determined that the District Court did not err regarding liability, we turn to the more complicated issue of damages.
A.
As a threshold matter, Philips contends that the District Court’s damages analysis was flawed because it rested on the admission of improper testimony. Specifically, Philips avers that the District Court erred under Rule 701 of the Federal Rules of Evidence in allowing Donlin to provide specialized or technical testimony regarding her compensatory damages. As to back pay, the District Court allowed Donlin to testify not only about her actual earnings, but also about her estimated lost earnings and pension benefits. With regard to front pay, Donlin’s testimony detailed the number of years she intended to work and the annual salary differential between Philips and the other companies where she was employed. In addition, Donlin estimated her future pension value, performed a probability of death calculation, and reduced her front pay award to its present value.
We review the District Court’s evidentiary rulings, including whether opinions are admissible under Rule 701, for abuse of discretion.
See United States v. Leo,
Rule 701 governs opinion testimony by lay witnesses:
If the witness is not 'testifying as an expert, the witness’ testimony in the form of opinions or inferences is limited to those opinions or inferences which are (a) rationally based on the perception of the witness, and (b) helpful to a clear understanding of the witness’ testimony or the determination of a fact in issue, and (c) not based on scientific, technical, or other specialized knowledge within the scope of Rule 702.
Fed.R.Evid. 701.
Subsection (c) was added in 2000 to “eliminate the risk that the reliability requirements set forth in Rule 702 will be evaded through the simple expedient of proffering an expert in lay witness clothing.” Fed.R.Evid. 701 advisory committee’s notes for the 2000 amendments [hereinafter Notes to 2000 Amendments];
see
*81
also United States v. Garcia,
This does not mean that an expert is always necessary whenever the testimony is of a specialized or technical nature. When a lay witness has particularized knowledge by virtue of her experience, she may testify — even if the subject matter is specialized or technical — because the testimony is based upon the layperson’s personal knowledge rather than on specialized knowledge within the scope of Rule 702.
See
Notes to 2000 Amendments. At the same time, we have consistently required that lay testimony requiring future projections of a business or operation come from someone who has intimate and thorough knowledge of the business gathered from either a lengthy tenure or a position of authority. For instance, in
Lightning Lube, Inc. v. Witco Corp.,
We have extended
Lightning Lube's
personal knowledge exception to plaintiffs testifying in employment discrimination suits. In
Maxfield v. Sinclair International,
In crediting Donlin’s testimony, the District Court relied principally on
Paolella v. Brouming-Ferris, Inc.,
Though Paolella might seem analogous to Donlin’s case, the District Court’s reliance thereon is problematic for two reasons. First, Paolella predated the 2000 amendment to Rule 701. That amendment added a new requirement for admissibility — subsection (c) regarding “technical” or “specialized” testimony — and we must question the vitality of Paolella in light of the additional requirement.
Second, the testimony offered in Paolella is distinguishable from Donlin’s case. The only front pay testimony given in Paolella related to straightforward evidence of the plaintiffs salary as well as an estimate that the plaintiff would work for another 14 years, until age 65; there was no indication Paolella required the witness to undertake complicated tasks such as calculating life-expectancy, assessing amortization rates, estimating pay raises, discounting to present value, or calculating earnings potential in a pension portfolio.
In that regard, our more recent holding in
Eichorn v. AT & T Corp.,
In accordance with Eichom, we find that the District Court should have barred *83 portions of Donlin’s testimony requiring technical or specialized knowledge. Donlin admitted that she was “not a professional,” nor a finance major or forensic economist. Under the Lightning Lube exception, Donlin’s testimony regarding facts within her personal knowledge (such as her current and past earnings) was appropriate. But, much of Donlin’s testimony went beyond those easily verifiable facts within her personal knowledge and instead required forward-looking speculation for which she lacked the necessary training. For instance, in calculating her front pay, Donlin speculated that Philips would provide a 3% annual pay raise; in fact, the company did not provide an increase of more than 1.3% in the years immediately prior to the trial. Additionally, having no experience with retirement benefits, Donlin misinterpreted Philips’s definition of “pensionable earnings” and erroneously assumed a flat 5% per year on pension earnings based only on an example in the Philips pension manual. After admitting that she had never performed a present-value discounting calculation prior to the day before trial, Donlin testified that she received instructions from her lawyer the night before regarding the proper discount rate. 5 Finally, Donlin misapplied the life expectancy charts and therefore did not properly account for the probability of her death.
In sum, Donlin’s testimony crossed the line into subject areas that demand expert testimony. Specifically, we find that Donlin’s testimony regarding the pension component of her back pay damages was improper.
6
On the issue of front pay, Donlin’s lay testimony was inappropriate with regard to her estimate of the annual pay raises at Philips, her estimated pension value, and the discounts she made for the probability of death and to find the present value of the award. Because this testimony was of a specialized or technical nature and was not within Donlin’s personal knowledge, the District Court abused its discretion in allowing her to offer it. A trial judge must rigorously examine the reliability of a layperson’s opinion by ensuring that the witness possesses sufficient specialized knowledge or experience which is germane to the opinion offered. As
plundh Mfg. Div. v. Benton Harbor Eng’g,
Furthermore, it is readily apparent that this error was not harmless.
See Hirst v. Inverness Hotel Corp.,
B.
In light of our decision to remand for further proceedings, we will address the remainder of Philips’s arguments to provide guidance to the District Court.
First, Philips contends that Donlin should not be entitled to compensatory damages because she found better employment after Philips refused to hire her. We must address both back pay and front pay.
1. Back Pay
Back pay is designed to make victims of unlawful discrimination whole by restoring them to the position they would have been in absent the discrimination.
See Loeffler v. Frank,
If the court finds that the respondent has intentionally engaged in or is intentionally engaging in an unlawful employment practice ... the court may enjoin the respondent from engaging in such unlawful employment practice, and order such affirmative action as may be appropriate, which may include ... any other equitable relief as the court deems appropriate.... Interim earnings or amounts earnable with reasonable diligence by the person or persons discriminated against shall operate to reduce the back pay otherwise allowable.
42 U.S.C. § 2000e~5(g).
Back pay is not an automatic or mandatory remedy, but “one which the courts ‘may’ invoke” at their equitable discretion.
Albemarle Paper Co. v. Moody,
Philips contends that back pay damages are not required because Donlin obtained full-time employment with another company, Romark Logistics, eight months after her employment with Philips ended. Donlin worked at Romark Logistics from September 2003 until August 2005 before voluntarily leaving to take a position at Mission Foods. Her employment at Mission Foods continued through the trial. Philips asserts that Donlin’s work at Romark restored her to the position she would have been in absent the alleged discrimination, and her back pay should terminate at the time she was rehired. 7
*85 In light of the facts found by the District Court, we disagree because Philips understates the requirements for an award of back pay and, as a result, comes to a legal conclusion that is inconsistent with the District Court’s findings of fact. Those findings of fact are no longer valid, however, because the numbers used by the District Court were based on improper testimony. Our analysis is nonetheless illustrative and should guide the District Court on remand.
From a legal perspective, the fact that Donlin found a job is insufficient by itself to demonstrate that she reestablished herself in the workplace such that she should be ineligible for back pay damages; the law requires that she find new employment that is “better or substantially equivalent.”
Ford Motor,
The District Court found, as a matter of fact, that Donlin would have made $182,923 working for Philips from the time of her termination until the time of trial and that she lost pension earnings in that same period in the amount of $9,453 for a total of $192,376. Damages Memorandum at *3. During that same time period, the District Court found that Donlin’s actual earnings were $129,326. Id. 8 Comparing the two figures, the District Court concluded as a matter of law, that Donlin suffered a back pay loss of $63,050 “based on the difference between the amount she earned from her discharge until the time of trial and the approximate amount she would have earned ... had she remained at Philips.” Id.
Philips asserts that Donlin received greater compensation than she would have received had she been hired by Philips because she worked overtime hours in her new job and received a greater annual pay raise than the raises given by Philips. Id. The District Court’s undisputed factual findings at the first trial do not comport with this conclusion, however. Instead, they indicate that Donlin earned less in her new job, even taking into account her overtime compensation and pay raise. 9 *86 These facts supported a finding that the two jobs were not substantially equivalent. If the evidence on remand supports a similar finding, the District Court should again conclude as a matter of law that Donlin can only be made whole — as Title VII demands — if awarded sufficient back pay to make up the difference.
2. Front Pay
Though back pay makes a plaintiff whole from the time of discrimination until trial, a plaintiffs injury may continue thereafter. Accordingly, courts may award front pay where a victim of employment discrimination will experience a loss of future earnings because she cannot be placed in the position she was unlawfully denied.
See Maxfield,
The jury recommended a front-pay award of $395,795 to cover the difference in Donlin’s salary and pension earnings for 25 years, adjusted to account for the probability of death and discounted to present value. The District Court modified that award, limiting front pay damages to 10 years, which totaled $101,800. Despite this reduction, Philips asserts that the District Court’s award of front pay was erroneous in two respects.
First, Philips claims that Donlin should not be entitled to front pay because she mitigated her damages by reestablishing herself in the workforce before trial. Philips cites
Ford Motor
for the proposition that damages are inappropriate where they “would catapult [the plaintiff] into a better position than they would have enjoyed in the absence of discrimination.”
*87 Second, Philips asserts that an award of front pay based on a 10-year period was inappropriate because it involved speculation regarding market conditions, Donlin’s future earnings, and her length of employment. The District Court agreed with this argument in part when it reduced the advisory jury’s award of front pay from 25 years to 10 years. Damages Memorandum at *3 (“An award of front pay until retirement at age 65, a twenty-five year period, would be too speculative.”). Philips contends that the time period is still too long, noting that the Mountaintop facility where Donlin was employed is subject to unpredictable market conditions — including adjustments in demand and the availability of exclusive contracts with major suppliers — which cannot be accurately estimated for 10 years.
Because a claimant’s work and life expectancy are pertinent factors in calculating front pay,
Anastasio v. Schering Corp.,
In
Goss,
the plaintiff complained that the District Court cut off her front pay after just four months, arguing that front pay should be extended because she was unlikely to earn as much money in her new sales job.
In
Green,
however, we distinguished
Goss
and imposed a two-year front pay award for a class of plaintiffs asserting discrimination in the hiring process of a Pennsylvania steel company.
Though the 10-year damages period granted by the District Court exceeds that awarded in
Green,
we note that there will often be uncertainty concerning how long the front-pay period should be, and the evidence adduced at trial will rarely point to a single, certain number of weeks, months, or years. More likely, the evidence will support a range of reasonable front-pay periods. Within this range, the district court should decide which award is most appropriate to make the claimant whole.
See, e.g., Whittington v. Nordam Group Inc.,
Such an exercise of discretion may result in an award different from what one or both of the parties would prefer. This possibility is caused by the inexactness of predictive evidence for front pay, and our standard of review (abuse of discretion) grants considerable leeway to district courts to grant an award that best serves Title VIPs remedial purpose.
We have not yet spoken precedentially regarding the precise length of time that is appropriate for an award of front pay. Indeed, in one case, a front-pay award of
X
years may be appropriate, while on different facts, a front-pay award for that same term of years would be inappropriate. These decisions are left to the sound discretion of the district court and every case must be considered on its particular facts. We note, however, that other courts of appeals have affirmed front-pay awards of 10 years or more.
See, e.g., Meacham v. Knolls Atomic Power Lab.,
Accordingly, we find that the District Court did not abuse its discretion when it awarded Donlin front pay for 10 years.
C.
Philips next argues that the District Court erred in calculating the amount of compensatory damages in light of Donlin’s subsequent employment decisions. In September 2003, eight months after Philips declined to hire her, Donlin found employment at Romark Logistics where she worked for nearly two years. In August 2005, Donlin voluntarily left Romark for a position at Mission Foods because it was closer to her home. Philips contends Donlin’s transfer to a lower-paying job at Mission was inconsistent with her duty to mitigate damages and the District Court erred by forcing Philips to suffer the decrease in Donlin’s wages in the form of increased compensatory damages. This argument is inconsistent with the record.
Damages are reduced under Title VII for “interim earnings or
amounts eamable with reasonable diligence
by the person or persons discriminated against.” 42 U.S.C. § 2000e-5(g)(1) (emphasis added). The availability of an equivalent or better job “terminates the ongoing ill effects” of the defendant’s discriminatory action, so the right to damages ends when such an opportunity becomes available.
Ford Motor,
Our sister circuit courts of appeals have held that one must make “reasonable efforts” to mitigate her loss of income, and only unjustified refusals to find or accept other employment are penalized.
NLRB v. Arduini Mfg. Co.,
Philips argues that Donlin’s 32-mile commute to Romark was not unreasonable and that many of the employees Donlin worked with at Philips commuted even farther. Because the commute to Romark was not unreasonable, Philips contends, Donlin failed to mitigate her damages by voluntarily accepting a lower-paying position at Mission. We disagree because simple math reveals that Donlin’s decision to work closer to home did not constitute a failure to mitigate. When Donlin left Romark, she was making $14.70 per hour, but when she moved to Mission, she was making only $13.00 per hour. 12 Despite the wage differential between the positions at Romark and Mission, when factoring the increased cost of Donlin’s commute to Romark into her overall compensation, we find that the positions were substantially equivalent and, therefore, Donlin’s decision to take a lower-wage job at Mission was reasonable. 13
Pursuant to our holding in
Le,
Philips was required, as the discriminating party, to demonstrate that substantially equivalent work was available, and that Donlin did not exercise reasonable diligence to obtain such employment.
See Le,
D.
Philips’s final assignment of error regards the District Court’s use of an inappropriate comparator to determine the compensation Donlin would have earned had she been hired by Philips. In calculating Donlin’s compensatory damages, the District Court compared the wages she received in her subsequent employment to what she would have earned had she been hired at Philips. In estimating what Donlin’s salary would have been at Philips, the court allowed Donlin to use the wages earned by Martha Matusick, a Philips employee with 15 years tenure, as her basis of comparison. Philips asserts this was erroneous because Donlin ignored the salaries of the male employees hired in her stead. We disagree.
We have held that for the purpose of determining
liability
in discrimination suits, a plaintiff “cannot selectively choose a comparator.”
Simpson v. Kay Jewelers,
Under that principle, we disagree that Matusick was an inappropriate basis of comparison. Although Matusick was long-tenured, the record evidence shows that Philips did not increase its employees’ salaries based on seniority. Additionally, there was evidence that Donlin and Matusick worked the same shift and worked similar amounts of overtime, both of which were key factors affecting compensation. Indeed, the District Court found as a matter of fact that Matusick was “an average employee with similar work habits and pension information.” Damages Memorandum at *3. Furthermore, the nine men Philips hired in lieu of Donlin would not have made good comparators because of their idiosyncratic employment histories. Specifically, the record shows that the men had quit, died, refused overtime, worked on different shifts, or had long periods of disability. Accordingly, on remand the District Court may determine Donlin’s compensatory damages by comparing her to Matusick or any other Philips employee with similar characteristics.
IV.
Finally, the parties dispute the amount of attorney’s fees awarded to Donlin as the prevailing party in this case. Donlin filed a motion for attorney’s fees
*91
and costs pursuant to 42 U.S.C. § 2000e-5(k) and Federal Rule of Civil Procedure 54(d), seeking $79,446, a fee multiplier of 25%, and costs in the amount of $6,195, for a total of $107,052. The District Court granted Donlin’s motion in part and denied it in part, awarding a total of $75,818 in fees and costs. Philips argues that the award was overly generous, whereas Donlin argues that the award was not high enough. We review the grant of attorney’s fees for abuse of discretion.
See P.N. v. Clementon Bd. of Educ.,
Philips contends that Donlin was not entitled to attorney’s fees because she failed to submit sufficient supporting evidence.
See Rode v. Dellarciprete,
On the other hand, we summarily reject Donlin’s counsel’s attempt to extract an additional $25 per hour without providing additional documentation. The party seeking an award of fees must justify the hourly rates of counsel and Donlin has failed to do so.
See Maldonado v. Houstoun,
Accordingly, we will affirm the District Court’s award of attorney’s fees.
V.
In sum, we find no reversible error regarding the District Court’s instructions to the jury, so we will affirm the judgment on liability. Nor was the District Court’s judgment regarding attorney’s fees erroneous. We find reversible error, however, regarding the District Court’s admission of testimony that required specialized or technical expertise. This improper testimony affected the District Court’s well-reasoned judgment with regard to mitigation as well as the amount of damages. Accordingly, we will vacate the judgment and remand for further proceedings consistent with this opinion. As noted above, the District Court may choose to hold a new trial, or, if it believes Donlin has had a “full and fair opportunity to present the case,”
see Weisgram,
Notes
. The jury’s role was only advisory on the issue of damages because back pay and front pay are equitable remedies to be determined by the court.
See Pollard v. E.I. du Pont de Nemours & Co.,
. Though we find in Donlin's favor regarding the liability verdict, we reject her cross-appeal
*80
that Philips was amenable to punitive damages. A Title VII plaintiff may recover punitive damages for intentional discrimination where "the complaining party demonstrates that the respondent engaged in ... discriminatory practices with malice or with reckless indifference to ... federally protected rights.” 42 U.S.C. § 198la(b)(1);
Le v. Univ. of Pa.,
. Contrary to Donlin’s assertion, Philips did not waive this issue in the District Court when it decided not to seek a mistrial during a sidebar. Philips objected to the introduction of damages evidence that Donlin withheld during discovery, not to the competency of Donlin’s testimony. By agreeing to proceed following the sidebar, Philips waived its objection to Donlin’s belated damages calculations, but that does not vitiate its objection to Donlin’s testimony on Rule 701 grounds. Indeed, Philips objected to Donlin’s testimony on this ground in both a motion in limine and at the conclusion of the first day of the trial.
. Rule 702 provides that:
If scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of an opinion or otherwise, if (1) the testimony is based upon sufficient facts or data, (2) the testimony is the product of reliable principles and methods, and (3) the witness has applied the principles and methods reliably to the facts of the case.
Fed.R.Evid. 702.
. The District Court's memorandum on damages suggests that discounting is best left to experts. In performing its own calculation, the District Court explained: "Some disagreement exists even among experts as to the methodology used to discount an award to present value.”
Donlin v. Philips Elec. N. Am. Corp.,
No. 3:05-CV-0585,
. There were two components of Donlin’s back-pay award: lost wages and lost pension earnings. While we approve of Donlin's testimony with regard to her lost wages, we find that the District Court improperly credited Donlin's testimony that she lost $9,453 in back pension benefits.
. Philips concedes that, given our affirmance of the adverse liability verdict, back pay is appropriate for the eight months between the date Philips terminated Donlin and the date Romark hired her.
. The District Court presented this factual finding as a lump sum for the entire back-pay period. It would have been helpful had the District Court broken down its analysis among three phases: Donlin’s period of unemployment (January to August 2003); her term of employment at Romark (September 2003 to August 2005); and her term of employment at Mission Foods (September 2005 to trial). We must compare Donlin's putative earnings at Philips to her actual earnings at Romark for the purpose of considering whether the Romark job was substantially equivalent; if the job at Romark was substantially equivalent to Philips, then Donlin’s compensatory damages should have ceased in August 2003 when she was hired by Romark regardless of whether she subsequently earned a lower salary at Mission.
Although the District Court provided a lump sum amount, we are able to extrapolate Donlin’s earnings at each phase of employment from Donlin’s trial exhibits, which were accepted by the District Court with minimal deviation. In doing so, we observe that Donlin's compensation at both Romark and Mission fell short of what she would have earned at Philips over that time period. Additionally, for reasons discussed in Section III.C, infra, we are convinced that the jobs at Romark and Mission are substantially equivalent with one another. On remand, however, the District Court should be more explicit with its findings and compare Donlin’s putative earnings at Philips to her actual earnings at Romark alone in order to gauge whether she found substantially equivalent employment.
. Philips claims it “does not dispute the district court’s findings of fact,” but disputes only the "failure to apply the law to those facts." Based on our understanding of the *86 trial exhibits and the District Court's findings, however, Philips's claim that Donlin received greater compensation at Romark than she would have at Philips is a factual claim that was rejected at trial.
. As we noted supra, the District Court’s findings regarding Donlin’s future salary were based on improper testimony. If the District Court finds on remand, considering the new damages evidence, that the job Donlin held at Romark was not substantially equivalent to or better than the job she would have held at Philips, then the following analysis regarding the proper length of the front-pay damages period will be applicable in the second trial. By contrast, if the District Court finds that Donlin’s Romark job was substantially equivalent or better than the job she would have held at Philips, then front pay would be unwarranted because Donlin would have mitigated her damages.
. The District Court was not required to submit the issue of front pay to the advisory jury in the first place because a bench trial is sufficient to determine an equitable award such as front pay.
See, e.g., Madden v. Chattanooga City Wide Serv. Dep’t,
. Donlin’s wages increased by 3.9% in her second year at Mission, or up to $13.51 per hour. At that time, Philips employees received $14.67 per hour as a base salary.
. Donlin's temporary position at Philips required a commute of less than 10 miles each way. By contrast, Romark was about 32 miles away, resulting in an increased daily commute of 44 miles round-trip. Donlin then voluntarily chose to leave Romark because Mission was located 20 miles closer to her home. The going mileage rate on the federal tax return for 2003 was 36 cents per mile. See Rev. Proc.2002-61, sec. 5, 2002-
