would impose an intolerable burden; “business” justifications for discharge can always be asserted. Jury instruction 9 set forth the same test as that endorsed by Laugesen and Loeb, and a stricter test is not warranted under the ADEA or interpretive case law.17
B. “Reasonable Factors” Instruction
American contends that the trial judge should have included defendant’s proposed instruction 5, which stated that a discharge is not unlawful if “for good cause or where the discharge or classification is based on reasonable factors other than age.” This instruction is an appropriate paraphrasing of the “reasonable factors” exception in 29 U.S.C. § 623(f)(1), but was unnecessary in this case because jury instruction 9 included the same language. There is no reason that this exception merits highlighting in a separate instruction.18
C. Instruction On The Weight Of Kelly’s Testimony
As a further assignment of error, American contends that the trial judge should have included defendant’s proposed jury instruction 16, which stated that a party’s testimony on alleged out of court admissions should be “considered with caution and weighed with great care.” Given the inherently self-serving nature of Kelly’s testimony, such an instruction may have been appropriate. However, failure to include the instruction was not error.
The jury was carefully instructed on its fact-finding function, and was competent to weigh the veracity of Kelly’s statements with the testimony of other witnesses. Jury instruction 8, 14, and 16 covered the preponderance of the evidence standard, plaintiff’s burden of proof, the veracity of witness testimony, and factors to consider in weighing testimony, including motive and state of mind. Instruction 16 specifically asked the jury to “[c]onsider also any relation each witness may bear- to either side of the case; [and] the manner in which each witness might be affected by the verdict .. . . ” Taken as a whole, the jury instructions were not misleading or unfair to American. Laugesen, 510 F.2d at 315.
D. Reduction In The Verdict To Conform To The Evidence
The jury award of pecuniary damages was slightly higher than the figures testified to by Kelly’s expert witness, Dr. Barnes. Barnes calculated Kelly’s income loss at $24,541.87, his pension loss at $1,241.51, and his business start-up costs at $6,248.50, for a total of $32,031.88. The jury awarded Kelly $25,000, $2,000, and $6,500 respectively, for a total of $33,500. The jury apparently accepted Dr. Barnes’ testimony, and rounded each figure up to an even amount, resulting in a total discrepancy of $1,462.12 between the testimony and the verdict.
This discrepancy does not mean that the verdict was inconsistent with the testimony, however. Barnes never claimed that his figures on the income and pension losses were exact. His total estimate of $25,-783.38 for these two items was based on a “conservative” average yearly increase of 4.8%, which he testified could have been as

The strong weight of authority supports some formulation of the determining factor test. See Smithers v. Bailar, 629 F.2d 892, 896-97 (4th Cir. 1980); Smith v. Flax, 618 F.2d 1062, 1066 (4th Cir. 1980); Goldman v. Sears, Roebuck & Co., 607 F.2d 1014, 1019 (1st Cir. 1979), cert. denied, 445 U.S. 929, 100 S.Ct. 1317, 53 L.Ed.2d 762 (1980) (ADEA and Title VII); Cleverly v. Western Elec. Co., 594 F.2d 638, 641 (8th Cir. 1979); Olsen v. Southern Pac. Transp. Co., 480 F.Supp. 773, 779 n.4 (N.D.Cal.1979). See also Smith & Leggette, supra, note 8, at 371-72. But see Brennan v. Reynolds & Co., 367 F.Supp. 440, 444 (N.D.Ill.1973).

Although inclusion of American’s proposed language in a separate instruction would have been proper, exclusion was equally proper. The jury instructions as a whole included the elements of a prima facie case under ADEA, as well as applicable defenses and exceptions. “If the judge’s instructions properly present the issues and the law as applicable, it is no ground for complaint that certain portions, taken by themselves and isolated, may appear to be ambiguous, incomplete, or otherwise subject to criticism.”
