Before McMILLIAN, BRIGHT, and BOWMAN, Circuit Judges.
                           ___________

BRIGHT, Circuit Judge.

       Dorman Hartley, a former employee, sued Dillard's, Inc., a department store
chain, for age discrimination after his termination. A jury awarded Hartley back pay
of $237,669.00. Based on a wilfulness finding by the jury, the district court1 awarded
Hartley front pay of $246,774.05, and attorney's fees and costs of $65,268.86.
Dillard's then filed a motion for judgment as a matter of law, or in the alternative a
new trial. The district court denied Dillard's motion. Dillard's brought this timely

appeal. Dillard's argues that the district court erred in denying the motion for
judgment as a matter of law on the basis that the evidence was insufficient for the jury
to decide discrimination, that on the alternative motion for a new trial the court erred
in instructing the jury on motive, that the testimony of Hartley's economist expert
should have been excluded, and that the calculation of back pay and front pay was
incorrect. We affirm the judgment.

I.    BACKGROUND

       Dillard's hired Hartley in 1987. In 1989, Dillard's promoted Hartley to the
store manager position at its McCain Mall store in North Little Rock, Arkansas.
Beginning in mid-1995, sales and profits at the McCain Mall Dillard's began
declining. Hartley was unable to meet the annual sales and profit goals Dillard's had
set for the McCain Mall store for fiscal years 1997, 1998, and the beginning of 1999.

      In 1998, Dillard's experienced changes in upper level management. Dillard's
promoted Tom Patterson to be the Little Rock district manager. Patterson served as
Hartley's immediate supervisor. Dillard's also named Burt Squires as the new
Corporate Vice President of Stores for the Arkansas Division.

       Between July 1998 and June 1999, Hartley, Patterson, and Squires met several
times to discuss the sales and profits of the McCain Mall store. As stated previously,
sales and profits continued to decline during this period. In August 1999, Dillard's
terminated Hartley, at age sixty-four, and replaced him with a thirty-two-year-old
manager. Hartley then brought this action against Dillard's.




                                          -2-
       At trial, Dr. Charles Venus, Hartley's expert witness, testified that nationally
malls were losing market shares to discount store chains and "big box" retail stores.2
Hartley also presented the testimony of two former Dillard's employees. Aubra
Carlton, an assistant store manager for Dillard's, and Dan Sparrow, a Dillard's district
manager, testified concerning statements made by Corporate Vice President Squires
that suggested age played a factor in the decision to terminate Hartley.

      A jury found in favor of Hartley and determined that Dillard's acted willfully.
With the finding of willfulness, the district court awarded Hartley front pay and
attorney's fees. As we have observed, the district court denied the post trial motions
and Dillard's brought this appeal.

II.   DISCUSSION

      A.     Judgment as a Matter of Law

       Dillard's contends that it was entitled to judgment as a matter of law on
Hartley's age discrimination claim because he failed to prove that Dillard's stated
reason for Hartley's firing was pretextual. We review the denial of a motion for
judgment as a matter of law de novo, and draw all reasonable inferences in favor of
the nonmoving party. Duncan v. Gen. Motors Corp., 

, 933 (8th Cir.
2002). Judgment as a matter of law is proper "when all the evidence points in one
direction and is susceptible to no reasonable interpretation supporting the jury
verdict." Blackmon v. Pinkerton Sec. & Investigative Servs., 

, 635 (8th
Cir. 1999).




      2
       "Big box" stores refers to free standing warehouse-retail chains, such as Wal-
Mart, Target, and Home Depot, that offer a variety of services.

                                          -3-
       Dillard's argued it terminated Hartley for unsatisfactory job performance,
including the decline of sales and profits at his store. However, Hartley introduced
expert testimony that mall sales were declining nationally. He also presented
testimony that other Dillard's stores had decreases in sales and profits and Dillard's
did not terminate those store managers. Hartley offered evidence that two other
Dillard's managers had poor performances and were not terminated, instead Dillard's
transferred them to other stores. Finally, Hartley provided testimony from co-workers
that indicated that Squires had age in mind when he terminated Hartley.

       Hartley introduced sufficient evidence for the jury to conclude that Dillard's
assertion of declining profits as the reason for discharge amounted to pretext and that
his age caused his discharge. "The factfinder's disbelief of the reasons put forward
by the defendant (particularly if disbelief is accompanied by a suspicion of
mendacity) may, together with the elements of the prima facie case, suffice to show
intentional discrimination." St. Mary's Honor Ctr. v. Hicks, 

, 511
(1993). The district court did not err in denying Dillard's motion for judgment as a
matter of law on the basis of all the evidence.

      B.     Jury Instruction

       We next address Dillard's contention that the district court erred when it
instructed the jury on both mixed motive and pretext theories of discrimination. We
review the jury instructions given by a district court for an abuse of discretion. See
Brown v. Sandals Resorts Int'l, 

, 953 (8th Cir. 2002). "Our review is
limited to whether the jury instructions, taken as a whole, 'fairly and adequately
represent the evidence and applicable law in light of the issues presented to the jury
in a particular case.'" 

v. GACS, Inc., 

, 679 (8th Cir.
2001)). We will not reverse "unless we find that the error affected the substantial
rights of the parties." Fogelbach v. Wal-Mart Stores, Inc., 

, 699 (8th Cir.
2001).

                                         -4-
       The framework for evaluating an age discrimination claim depends on the type
of evidence presented in support of the claim. Where the plaintiff relies primarily on
circumstantial evidence, courts apply an analysis as set forth in McDonnell Douglas
Corp. v. Green, 

(1973). Under McDonnell Douglas, after establishing
a prima facie case, the plaintiff must prove by the preponderance of the evidence that
the nondiscriminatory reasons offered by the employer were pretext for
discrimination. See Smith v. Allen Health Sys., Inc., 

, 833 (8th Cir.
2002).

       However, when a plaintiff can produce direct evidence that an illegal criterion
was a motivating factor in the employment decision, the court uses the framework as
set out in Price Waterhouse v. Hopkins, 

(1989). The mixed motive
framework allows for declaratory relief, injunctive relief, attorney's fees and costs
once the plaintiff meets his initial burden regarding direct evidence. Gagnon v. Sprint
Corp., 

, 847-48 (8th Cir. 2002). Thus, the employer is liable for
discrimination upon direct evidence that it acted on the basis of a discriminatory
motive. 

not the employer satisfies its burden to show by a
preponderance that it would have reached the same employment decision absent any
discrimination is only relevant to determine whether the court may award full relief
including damages, court ordered admissions, reinstatement, hiring, promotion or
other such relief. 

case, the district court instructed the jury on both mixed motive and
pretext theories using the special interrogatories as set forth in the Eighth Circuit's
Civil Model Jury Instruction 5.92. This jury instruction was designed for use when
a case cannot easily be classified as either a mixed motive case or a pretext case. The
instruction is intended to elicit the jury's categorization of the case at issue. The
committee comments to the instruction provide:




                                         -5-
            These special interrogatories are designed for use where the trial
      court is inclined to adhere to a mixed motive/pretext distinction but
      cannot readily classify a case under a "mixed motive" or "pretext"
      theory. For example, if plaintiff presents some direct evidence which
      does not clearly address the employment decision at issue, such as
      general statements of age bias by the employer, it may be unclear
      whether the case should be submitted under a "mixed motive" or
      "pretext" instruction.

EIGHTH CIR. MODEL JURY INSTR. § 5.92 cmt. (2001).

       Dillard's argues that the use of this instruction was improper because there was
no direct evidence of discrimination to entitle Hartley to a mixed motive instruction.
Hartley presented the testimony of Dillard's operations manager, Aubra Carlton.
Carlton testified that Squires directed her to "go out and hire some young guys" at a
job fair. In addition, Hartley offered the testimony of Dan Sparrow, another store
manager, who described another age-related situation. Sparrow testified that Squires
asked him to remove two older women from their manager positions with Dillard's.
Not only did Hartley offer some direct evidence of discrimination, he also offered
circumstantial evidence on how he was treated differently in regard to profits at the
store compared with other store managers. After careful review of the record, we
agree that the evidence could reasonably be characterized to support a mixed motive
theory of discrimination.

        Dillard's also contends that the pretext portion of the instruction misstated this
court's standard for finding pretext by requiring that the jury find that age was "a"
determining factor rather than "the" determining factor. We have previously
approved of instructions stating "the" determining factor as the correct standard. See
Rockwood Bank v. Gaia, 

, 842 (8th Cir. 1999) ("the plaintiff must prove
that the prohibited factor was the determining factor, not merely a determining factor,
in the adverse employment decision"); Foster v. Univ. of Ark., 

, 115 (8th


                                           -6-
Cir. 1991) (deciding that "the" determining factor not "a" determining factor correct
standard in racial discrimination case under pretext theory).

       However, we have also approved of the "a" determining factor standard. See
Calder v. TCI Cablevision of Mo., Inc., 

, 729 (8th Cir. 2002) ("Calder
must then present evidence sufficient . . . to create a reasonable inference that age was
a determinative factor" (emphasis added)); Fisher v. Pharmacia & Upjohn, 

, 919 (8th Cir. 2000) ("Fisher must then present evidence sufficient to raise a
question of material fact as to whether Pharmacia's proffered reason was pretextual
and to create a reasonable inference that age was a determinative factor in the adverse
employment decision."); Erickson v. Farmland Indus., Inc., 

, 726 (8th
Cir. 2001) ("Erickson must present sufficient evidence to . . . create a reasonable
inference that age was a determinative factor."). Taking the jury instructions as a
whole, they adequately represent the law in this case. See 

(stating no grounds for reversing where jury instructions adequately represented the
law). Any error in using "a" instead of "the" determinative factor did not constitute
harmful error when the jury relied on the McDonnell Douglas formulation to find
discrimination.3

      C.     Admission of Expert Testimony

       Dillard's next contends a new trial should be granted because the expert
opinion of Dr. Venus, an economist, was not based on sufficient facts and data,
scientific principles, and reliable methods. Dr. Venus testified on the computation
of damages and the economics of employability and external factors affecting mall
and retail store sales. Hartley presented Dr. Venus' testimony to support his position

      3
       Even if the evidence did not support a mixed motive theory, the instruction did
not substantially affect Dillard's rights. See 

. The jury did
not answer the interrogatory for mixed motive because it had already found for
Hartley on the pretext theory.

                                          -7-
that Dillard's used declining profits to justify Hartley's termination. Dr. Venus
testified that the financial problems of the McCain Mall store were consistent with
what was happening to department stores in malls around the country.

      Expert testimony is admissible if it is reliable and will help the jury understand
the evidence or decide a fact in issue. Fed. R. Evid. 702; see also Miles v. Gen.
Motors Corp., 

, 724 (8th Cir. 2001). We review the admission of expert
testimony for the abuse of discretion. See In re Air Crash at Little Rock Ark., on June
1, 1999, 

, 509 (8th Cir. 2002).

       Dillard's contends that Dr. Venus' testimony is not based on sufficient facts or
data because some of the materials that he relied on do not squarely support his
testimony. Dillard's also argues that Dr. Venus failed to consider the economic
realities specifically applicable to the McCain Mall store. Under Federal Rule of
Evidence 702, a trial judge, in admitting expert testimony, has a gatekeeping
responsibility to "ensur[e] that an expert's testimony both rests on a reliable
foundation and is relevant to the task at hand." Kumho Tire Co. v. Carmichael, 

, 141 (1999) (citing Daubert v. Merrell Dow Pharm., Inc., 

, 597
(1993), and applying Daubert to the testimony of engineers and other experts).

       "As a general rule, the factual basis of an expert opinion goes to the credibility
of the testimony, not the admissibility, and it is up to the opposing party to examine
the factual basis for the opinion in cross-examination. Only if the expert's opinion
is so fundamentally unsupported that it can offer no assistance to the jury must such
testimony be excluded." Bonner v. ISP Tech., Inc., 

, 929-30 (8th Cir.
2001) (quoting Hose v. Chicago Northwestern Transp. Co., 

, 964 (8th Cir.
1996) (internal citations and quotations omitted)).

       Dr. Venus has performed similar economic comparisons for more than fifteen
years, including other analyses of retail establishments. His testimony explained the

                                          -8-
general trend of mall stores losing market share to non-mall competitors, and this
would explain the general loss of profits at the McCain Mall store. While Dr. Venus'
testimony may not have addressed the specific financial conditions of the McCain
Mall store, the jury could consider this evidence on the profit questions relating to the
discharge. We conclude that the district court did not abuse its discretion under
Kumho Tire in admitting Dr. Venus' testimony.

      D.     Calculation of Back Pay

      Dillard's presents two issues for error in Hartley's back pay award. First,
Dillard's argues that Hartley's back pay should be reduced because he failed to
mitigate his damages by seeking other employment after his termination. Second,
Dillard's contends that the district court erred in failing to deduct certain amounts
from the jury's award of back pay.

             1.     Mitigation

       A party harmed by discriminatory employment decisions has an affirmative
duty to mitigate his damages by reasonably seeking and accepting other substantially
equivalent employment. See Mathieu v. Gopher News Co., 

, 783-84
(8th Cir. 2001). The employee need not go into another line of work, accept a
demotion, or take a demeaning position. 

A plaintiff's efforts to mitigate
need not be successful but must represent an honest effort to find substantially
equivalent work. 

the district court's finding that a plaintiff used
reasonable efforts to mitigate for clear error. See Kehoe v. Anheuser-Busch, Inc., 

, 1106 (8th Cir. 1996).

      The burden remains on the employer to show that the employee failed to
mitigate his damages. See Brown v. Stites Concrete, Inc., 

, 565 (8th Cir.
1993). Dillard's attempts to explain away its burden of proving the availability of

                                          -9-
substantially equivalent employment by arguing that Hartley forfeited his right to
claim damages because he did not seek employment after November 2000.

      However, the district court determined that Hartley "has made a reasonable
attempt to mitigate his damages." (App. at 65.) Further, the district court explained:

      I am persuaded by Dr. Venus' testimony that it is difficult for a person
      with [Hartley's] skills to find a comparable job when he is so close to
      retirement age. Defendant bears the burden of showing that there were
      suitable positions and that Plaintiff failed to use reasonable care in
      seeking them. Defendant failed to do so.

(App. at 65.) Based on our review of the record, the district court's characterization
of Hartley's mitigation does not amount to clear error.

             2.    Back Pay Deductions

      We next address Dillard's contention that the district court erred in failing to
reduce certain amounts from Hartley's back pay award. We review a district court's
award of back pay for clear error as to factual findings. See Glover v. McDonnell
Douglas Corp., 

, 910 (8th Cir. 1998).

       A district court is obligated to grant a plaintiff who has been discriminated
against on account of his age, the most complete relief possible. See Maschka v.
Genuine Parts Co., 

, 572 (8th Cir. 1997). Back pay in an age
discrimination case is the difference between the value of the compensation the
plaintiff would have been entitled to had he remained employed by the defendant and
whatever wages he earned during the relevant period. See Brennan v. Ace Hardware
Corp., 

, 373 (8th Cir. 1974).




                                        -10-
       Dillard's challenges the inclusion of payments for health, life and other forms
of insurance, contributions to Hartley's retirement plan, accrued vacation, and the
value of Hartley's employee discount. We have held that on proper foundation, an
employee may recover benefits other than lost wages such as lost 401(k)
contributions, and the replacement of life and disability insurance that had been paid
by the employer. See Gaworski v. ITT Commercial Fin. Corp., 

, 1114
(8th Cir. 1994). Further, other courts have allowed the recovery of various fringe
benefits of employment such as vacation time, employee meal discounts, health
insurance coverage, lost stock options, and travel expenses. See Munoz v. Oceanside
Resorts, Inc., 

, 1348 (11th Cir. 2000) (upholding back pay award that
included vacation time, employee meal discounts, and health insurance coverage); see
also Greene v. Safeway Stores, Inc., 

, 1243 (10th Cir. 2000) (allowing
for recovery of lost stock options that would have vested, but for the illegal
termination); Brunnemann v. Terra Int'l, Inc., 

, 178 n.6 (5th Cir. 1992)
(allowing former employee to recover $750 a month in lost travel expenses the
employee was entitled to while working); Kelly v. Matlack, Inc., 

, 984-
85 (3d Cir. 1990) (allowing for the recovery of vacation, sick leave/funeral leave,
short and long term disability, tuition aid program, medical benefits, and pension plan
contributions, where employee handbook noted these among the "invisible paycheck"
that the employee receives as a benefit of employment). Based on our review, the
district court did not clearly err in refusing to deduct the specific amounts contested
by Dillard's from Hartley's back pay award.

      E.     Front Pay Award

       Finally, Dillard's claims that the district court erred in awarding front pay to
Hartley and in its calculation. We review the award of front pay for the abuse of
discretion. See 

.




                                         -11-
        First, Dillard's argues the district court erred in awarding front pay until Hartley
reached age sixty-eight. Dillard's contends Hartley's front pay award should be
limited because he failed to continue looking for work prior to trial. At trial, Hartley
testified he had planned to work for Dillard's until age sixty-eight. He provided
expert testimony that given his education, age, and employment, it was unlikely he
would ever achieve the level of income and benefits he enjoyed in his prior position.
We have affirmed a front pay award for the remainder of the plaintiff's working life,
where he had been employed by the defendant for twenty-three years. See Newhouse
v. McCormick & Co., 

, 641-42 (8th Cir. 1997) ("If a plaintiff is close to
retirement, front pay may be the only practical approach."). Hartley also provided
evidence that his attempts to mitigate damages had failed. Viewing the record in this
case as a whole, the district court did not abuse its discretion by ordering front pay.

       Dillard's also asserts that the district court erred in calculating Hartley's front
pay award by including the recovery of benefits such as COBRA payments,4 vacation
pay, and employer contributions towards benefits. Front pay is a monetary substitute
to reinstatement, which the district court in its discretion may award under the Age
Discrimination in Employment Act to make the injured party whole. See 

. The front pay award should address the equitable needs of the
employee, such as the ability to obtain employment with comparable compensation.
See E.E.O.C. v. HBE Corp., 

, 555 (8th Cir. 1998). The front pay
determination is left to the district court's discretion. See Salitros v. Chrysler Corp.,
___ F.3d ___, 

, *7 (8th Cir. Oct. 3, 2002). Because the purpose
of awarding front pay is to compensate the plaintiff for what he would have had but
for his wrongful termination, the district court did not err in refusing to reduce
Hartley's award for vacation pay and employer contributions. See Belk v. City of


       4
       The Consolidated Omnibus Budget Reconciliation Act (COBRA) contains
provisions giving certain former employees the right to temporary continuation of
health coverage for themselves and their families at group rates.
