Opinion for the Court filed by Chief Judge WALD.
Opinion dissenting in part and concurring in part filed by Senior Circuit Judge MacKINNON.
WALD, Chief Judge:
After a jury verdict awarding appellee Albert Z. Hodge $175,000 for breach of an employment contract, appellant Evans Financial Corporation (“Evans”) seeks review of the District Court’s denial of its motions for judgment n.o.v. and a new trial. Hodge claimed that he had been discharged from his position as general counsel of Evans in violation of an oral agreement by Evans to employ him permanently. The District Court denied Evans’ motion for a directed verdict and refused to instruct the jury on the statute of frauds defense asserted by Evans. Following the jury’s verdict, Evans’ motions for judgment n.o.v. and new trial were also denied. In this appeal, Evans again argues that the oral employment contract is unenforceable under the District [561]*561of Columbia statute of frauds and makes several other objections to the jury’s verdict. Although we reject most of these challenges, we agree with Evans that the trial court erred in allowing Hodge to present to the jury evidence concerning two items of damages to which he was not entitled. We therefore affirm the judgment of the District Court on condition that the appellee remit the portion of the award which might be attributable to those items.1
I. Background
On two occasions in 1980, Hodge met with Jon Tilley, president and chief operating officer of Evans Financial Corporation, to discuss Hodge’s possible employment by Evans. Hodge was at that time assistant counsel and assistant secretary of Mellon National Corporation and Mellon Bank of Pittsburgh. According to Hodge’s trial testimony, Tilley asked Hodge at the second meeting what his conditions were for accepting employment with Evans. Hodge replied, “No. 1, the job must be permanent. Because of my age, I have a great fear about going back into the marketplace again. I want to be here until I retire.” Trial Transcript (“Tr.”) at 109. Hodge testified that Tilley’s response was “I accept that condition.” Tr. at 110. Hodge subsequently accepted an offer of employment as vice president and general counsel of Evans. He moved from Pittsburgh to Washington, D.C. in September, 1980, and worked for Evans from that time until he was fired by Tilley on May 7, 1981.
Hodge then brought this diversity action in the District Court, alleging that his termination violated Evans’ promise of permanent employment. The District Court initially granted summary judgment for Evans, ruling that all employment contracts for an indefinite period of time are terminable at will as a matter of law. Hodge v. Evans Financial Corp., No. 81-2726, slip op. at 6-7 (D.D.C. Apr. 15, 1982). This court reversed and held that “[t]hough the classic assumption of the law is that the parties intend a contract of indefinite term to be terminable at will, basic principles of contract law inform us that the parties can contract otherwise.” Hodge v. Evans Financial Corp., 707 F.2d 1566, 1568 (D.C. Cir.1983). The court concluded that Hodge was entitled to an opportunity to demonstrate that the employment contract between Evans and Hodge was intended to be of indefinite duration and terminable only for cause and remanded to the District Court. Id. at 1570. The case was then tried to a jury, which found for the plaintiff and awarded him $175,000 in damages.
II. Analysis
A. Enforceability of the Agreement Under the District of Columbia Statute of Frauds
Evans argues that the oral employment agreement between Evans and Hodge is unenforceable under the statute of frauds as enacted in the District of Columbia, which provides, in relevant part, that:
An action may not be brought ... upon an agreement that is not to be performed within one year from the making thereof, unless the agreement upon which the action is brought, or a memorandum or note thereof, is in writing ... and signed by the party to be charged therewith or a person authorized by him.
D.C.Code § 28-3502. Because the agreement here contemplated long-term employment for a number of years, Evans argues that the statute requires it to have been in writing in order to be enforceable.
Despite its sweeping terms, the one-year provision of the statute has long been construed narrowly and literally. Under the prevailing interpretation, the enforceability of a contract under the statute does not depend on the actual course of subsequent events or on the expectations of the parties. Instead, the statute applies only to those contracts whose performance could not possibly or conceivably be completed within one year. The statute of frauds is thus inapplicable if, at the time [562]*562the contract is formed, any contingent event could complete the terms of the contract within one year. See, e.g., Restatement (Second) of Contracts § 130 comment a (1979); 2 Corbin on Contracts § 445, at 542-43 (1950 & Supp. 1984) (“It makes no difference how improbable it is that the condition will occur within a year; if there is any possibility that it may so happen, the statutory provision is not applicable.”); 3 Williston on Contracts § 495, at 577-83 (3d ed. 1960) (same).
This interpretation of the statute has been adopted by the District of Columbia courts. The District of Columbia Court of Appeals recently stated that if a contract is “by its terms capable, possible, or susceptible of performance within one year, the statute of frauds does not apply and an oral agreement may suffice.” Launay v. Launay, Inc., 497 A.2d 443, 449 n. 4 (D.C.1985) (citing Snyder v. Hillegeist, 246 F.2d 649, 651 (D.C.Cir.1957)); see also Coan v. Orsinger, 265 F.2d 575, 578 (D.C.Cir.1959) (“If the contingency which fulfills and completes the terms of the contract happens or could possibly happen within a year, the contract is not within the statute.”).
Hodge argues that, under this interpretation of the statute of frauds, a permanent or lifetime employment contract does not fall within the statute because it is capable of full performance within one year if the employee were to die within the period. Hodge’s view of the statute’s applicability to lifetime or permanent employment contracts has, in fact, been accepted by an overwhelming majority of courts and commentators. See Restatement (Second) of Contracts § 130 illustration 2 (1979) (“A orally promises to work for B, and B promises to employ A during A’s life at a stated salary. The promises are not within the one-year provision of the Statute, since A’s life may terminate within a year.”); Restatement (First) of Contracts § 198 illustration 2 (1930) (same); Restatement (Second) of Agency § 414 comment a (1958) (same); 2 Corbin on Contracts § 446, at 549 & n. 35 (1950 and Supp.1984) (“A contract for ‘permanent’ employment is not within the one-year clause for the reason that such a contract will be fully performed, according to its terms, upon the death of the employee.”); E. Farnsworth, Contracts § 6.4, at 394 (1982) (same); 3 Williston on Contracts § 495, at 579-81 & n. 8 (3d ed. 1960) (same); 72 Am.Jur.2d Statute of Frauds § 42 (1974 & Supp.1984) (“It is a well-settled general rule that a contract ... to employ one for the duration of his life [or] a contract to give one ‘permanent’ employment ... is not within [the statute] for the reason that contracts of this description are deemed possible of performance within one year from their formation, since, for example, the employee may die within that period.”) (footnotes omitted).
Although the local courts have not directly spoken on the applicability of the statute to permanent employment contracts, the vast majority of the state courts faced with this issue have squarely and unequivocally held that contracts such as Hodge’s fall outside the statute.2 As a diversity court, we must make a conscientious attempt to predict whether local [563]*563courts would accept the prevailing view of the statute of frauds in light of the relevant indications in local law and elsewhere. See generally 19 C. Wright, A. Miller & E. Cooper, Federal Practice and Procedure § 4507 (1982). In Cooper v. Saunders-Hunt, 365 A.2d 626, 629 (D.C.1976), the highest local court adhered to the conventional, narrow interpretation of the one-year provision by concluding that an indefinite oral partnership agreement does not fall within the statute. See id. (“An oral partnership agreement [for an indefinite period of time] would not run afoul of the Statute of Frauds, since no term of years was ever fixed by the agreement and therefore it was capable of performance within one year.”) (citing Snyder, 246 F.2d at 651). This court has also recognized, albeit in dicta, that employment contracts of an uncertain or permanent duration are excluded from the statute. See Farrow v. Cahill, 663 F.2d 201, 207 n. 29 (D.C.Cir.1980) (“[A] promise to serve as an employee as long as the employee lives ... is ... clearly outside the Statute.”) (discussing Williston). In sum, the prevailing view is that Hodge’s permanent employment contract is not barred by the statute of frauds, and there is no reason to believe that the District of Columbia courts would depart from the conventional interpretation of the statute in this case.
In arguing that oral long-term employment contracts are unenforceable under the statute, Evans relies on dicta in two federal district court cases. See Prouty v. National R.R. Passenger Corp., 572 F.Supp. 200, 204 (D.D.C.1983); Gebhard v. GAF Corp., 59 F.R.D. 504, 506 (D.D.C. 1973). Neither of those cases, however, mentioned the conventional view that permanent employment contracts are outside the statute, and neither attempted to predict how local courts would treat such a contract in light of Snyder (now reaffirmed in Launay) and Cooper. These district court cases therefore provide no reliable authority or even suggestion that District of Columbia courts would not follow the conventional interpretation of the statute of frauds.
Further, in both Prouty and Gebhard, plaintiffs alleged that the oral employment contracts at issue guaranteed them employment for a specified period of time — until they reached the age of sixty-five. See 572 F.Supp. at 204; 59 F.R.D. at 506. In neither case did the alleged contract provide for indefinite, lifetime or permanent employment. Under the conventional view of the statute, an oral employment contract for a stated, definite term of years exceeding one year (like those alleged in Prouty and Gebhard) is unenforceable on the rationale that the employee’s possible death within one year would “defeat” rather than “complete” the express terms of the contract.3
The employment contract in this case cannot reasonably be interpreted as a contract for a specified period of time, however. Hodge unequivocally alleged a contract for permanent employment, not a contract until he reached age sixty-five or for any other stated period of time. See Complaint 116, Record Excerpts at 13; Hodge, 707 F.2d at 1567 (“The complaint ... stated that ... Tilley promised Hodge that his employment would be permanent.”). Evans has not at any point in this lawsuit argued that Hodge and Tilley entered into a contract for any definite period of time. To the contrary, Evans has consistently argued that Hodge must be deemed to be an at-will employee precisely because he was not promised employment for “any fixed period of time.” Brief of Appellant at 11; see also id. at 13,15-16; Hodge, 707 [564]*564F.2d at 1566-67 & n. 3.4 In various pretrial memoranda, moreover, the parties definitely stipulated that Hodge and Tilley had not entered into a contract for any fixed period of time. See Pretrial Brief of Defendant, Record Item 54, at 32-33; Reply of Plaintiff to Defendant’s Pretrial Brief, Record Item 55, at 3.
The fact that Hodge expected to retire at some point does not mean that his contract could not possibly be performed within one year. All employment contracts of permanent, lifetime or indefinite duration undoubtedly contemplate retirement; such contracts certainly do not, as a matter of law, mean that employees are bound to work until the moment they drop dead. Hodge’s permanent employment contract with Evans could therefore be fully performed, according to its terms, upon Hodge’s retirement or upon his death. Under the conventional view of the statute, the latter possibility is sufficient to take the contract out of the statute. See, e.g., 2 Corbin on Contracts § 454 (contracts susceptible of alternative performances are outside the statute if any one of the alternatives could possibly be performed within one year); 3 Williston on Contracts § 498 (same). That Hodge expected to retire before he died is completely irrelevant to this case so long as the contract was legally susceptible of performance within one year. The applicability of the statute of frauds does not depend on the expectations of the parties.
There is no indication in local law or elsewhere that a permanent employment contract should be construed as a contract for an expressly stated, fixed term of years by virtue of an employee’s expectation that he or she will retire at some point.5 No court or commentator has ever suggested that the possibility of the employee’s death within one year would “defeat” rather than “complete” such a contract. To the contrary, courts and commentators have consistently accepted the view that indefinite permanent employment contracts such as Hodge’s .fall outside the statute because they are capable of full performance within one year. See, e.g., 2 Corbin on Contracts § 446, at 549-50 (Permanent employment contracts fall outside the statute because “[t]he word ‘permanent’ has, in this connection, no more extended meaning than ‘for life.’ ”); 3 Williston on Contracts § 495, at 582 (“A promise of permanent personal performance is on a fair interpretation a promise of performance for life, and therefore not within the Statute.”).
Evans asserts finally that a letter from Tilley to Hodge confirming salary and benefit matters brings Hodge’s contract within the statute because it established a fixed da,te in the future, more than a year from the making of the contract, for the payment of Hodge’s first bonus. That letter, which was dated July 31, 1980, states in relevant part:
I am pleased to welcome you to Evans. I thought it would be useful to confirm in writing a number of items.
Your position will be Vice President and General Counsel of Evans Financial Corp. This position is a Grade 63 and initial salary will be at the annual rate of $47,500. In addition, a minimum bonus of $6000 is guaranteed for 1981 (payable January, 1982). In the event actual bonus exceeds this amount, you will receive [565]*565the higher amount. I have enclosed a summary of our current bonus plan with this letter....
Letter from Jon Tilley to Albert Hodge 1 (July 31, 1980), Record Excerpts at 161. Because Hodge’s, first bonus was payable in January of 1982, Evans argues, the contract “contemplated employment extending to and beyond” that date and therefore could not be performed within one year. See Brief of Appellant at 38.
Tilley’s letter constitutes nothing more, however, than a routine confirmation of a particular contract term — Hodge’s salary scale — that is irrelevant to whether Hodge was promised permanent employment. It does not address the duration of Hodge’s employment, and it certainly does not purport to establish an employment contract for any fixed period of time. Courts have specifically and consistently held that the presence of bonus or salary terms payable after one year does not bring a long-term indefinite employment contract within the statute. See, e.g., White Lightning Co. v. Wolfson, 68 Cal.2d 336, 438 P.2d 345, 66 Cal.Rptr. 697 (1968) (Tobriner, J.): Murphy v. Buschman-Jennings, Inc., 382 S.W.2d 29 (Mo.App.1964); Miller v. Riata Cadillac Co., 517 S.W.2d 773 (Tex.1974). At most, Tilley’s letter indicates only that Evans expected Hodge to work through January of 1982 — an expectation that does not bring a permanent employment contract within the statute.
Hodge alleged and proved that Evans promised him indefinite permanent employment. Under settled legal principles, such contracts are not barred by the statute of frauds. We recognize that the conventional view of the statute is somewhat “legalistic.” Yet the statute of frauds itself is widely understood as a formal legal device that shields promise breakers from the consequences of otherwise enforceable agreements. See, e.g., Farrow, 663 F.2d at 207 n. 29; Hackney v. Morelite Construction, 418 A.2d 1062, 1065-67 (D.C.1980); 2 Corbin on Contracts § 444 (1950 & Supp.1984). The conventional, narrowing interpretation overwhelmingly adopted by courts and commentators is designed to mollify the often harsh and unintended consequences of the statute. See Restatement (Second) of Contracts § 130 comment a (1979). Here the jury concluded, despite Evans’ vigorous defense, that Hodge was promised permanent employment and that he was nonetheless fired without cause. Under the traditional, narrow view of the statute generally endorsed by Launay and Cooper and explicitly adopted by the vast majority of courts and commentators, the statute of frauds does not bar the enforcement of such jury verdicts.
B. Sufficiency of the Evidence
Evans argues that there was not sufficient evidence from which a reasonable jury could conclude that the parties agreed to a permanent employment contract which was terminable only for cause, and that therefore the District Court erred in denying Evans’ motion for judgment n.o.v. A motion for judgment n.o.v. should be granted only if “the evidence, together with all inferences that can reasonably be drawn therefrom is so onesided” that reasonable persons could not disagree as to the verdict. Vander Zee v. Karabatsos, 589 F.2d 723, 726 (D.C.Cir.1978), cert. denied, 441 U.S. 962, 99 S.Ct. 2407, 60 L.Ed.2d 1066 (1979).
In its earlier opinion in this action, this court held that Hodge could prove that he was promised permanent employment terminable only for cause by presenting evidence of “the express terms of the contract, ... surrounding circumstances, or the existence of additional consideration— for example, plaintiff’s willingness to leave a secure position in a different city in order to begin employment with defendant.” Hodge, 707 F.2d at 1569. At trial, Hodge presented evidence both that Tilley expressly promised him permanent employment until retirement and that he, Hodge, gave “additional consideration” in exchange for that promise. See Tr. at 109-10 (Hodge told Tilley that “the job must be permanent.... I want to be here until I retire”; Tilley unequivocally accepted that condition); id. at 122 (security of permanent employment with Evans induced Hodge to leave his previous job and to [566]*566move his family to Washington). Under the legal standard set out in Hodge, this evidence is sufficient to defeat a motion for judgment n.o.v. on the issue of whether the parties entered into a permanent employment contract.
Evans relies on three types of allegedly conflicting evidence to argue that Hodge’s employment was not intended to be permanent. First, Evans points to elements of Hodge's testimony that might conceivably undermine its credibility. See, e.g., Tr. at 212-13 (Hodge contrasted his understanding of “permanent” employment with employment “for a term of 30 days or 60 days or 90 days or something of that sort”); id. at 254 (Hodge failed to ask Tilley for a written agreement that he could only be discharged for cause; such an agreement “didn’t have any bearing on anything we had ever discussed”). But it is clear from the jury’s verdict that it accepted as true Hodge’s testimony concerning the agreement he reached with Tilley. Our review of the District Court’s denial of the motion for judgment n.o.v. is limited by the principle that “[t]he weighing of conflicting evidence and the evaluation of witness credibility is exclusively within the jury’s province.” Carter v. Duncan-Huggins, Ltd., 727 F.2d 1225, 1234 (D.C.Cir.1984). We cannot disturb the jury’s credibility determination simply because of the existence of conflicting evidence which the jury apparently considered and found insufficient to discredit Hodge’s account of what occurred.
Second, Evans argues that there was no evidence of “additional consideration” in this case because Hodge had independent reasons for moving his family back to Washington, where he had lived before moving to Pittsburgh. Hodge did concede on cross-examination that a desire to return to Washington, where he had friends and family, was “a factor” in his decision to accept employment with Evans, but he also noted that he “had friends and family in Pittsburgh.” Tr. at 221. This evidence again created a credibility question for the jury, which the jury apparently resolved by concluding that Hodge was motivated to return to Washington in large part by Evans’ promise of permanent employment.
Finally, Evans contends that Tilley’s July 31, 1980, letter to Hodge set out all relevant “terms and conditions of employment,” see Brief of Appellant at 16, and that its failure to state that Hodge’s employment was to be permanent or that he could only be terminated for cause contradicts Hodge’s testimony concerning the oral promise of permanent employment. Tilley stated in the letter, however, that he “thought it would be useful to confirm in writing a number of items,” and there was no indication that the letter was intended to summarize all of the terms of the parties’ agreement with respect to Hodge’s employment. See Letter from Jon Tilley to Albert Hodge 1 (July 31, 1980), Record Excerpts at 161. The letter’s focus on salary and benefits was consistent with Hodge’s testimony that he and Tilley decided not to negotiate about salary during the meeting at which Tilley accepted Hodge’s condition that his employment must be permanent, but that Hodge’s salary was negotiated at a later time through an intermediary. See Tr. at 111, 115-16. Tilley’s letter could reasonably be interpreted as a confirmation of those matters that Tilley and Hodge had not agreed to during their meetings. We conclude that there was sufficient evidence from which the jury could reasonably determine that Evans and Hodge agreed to enter into a permanent employment contract, and that the jury could and apparently did choose to reject the pieces of conflicting evidence that were in the record.
C. Jury Instructions
Evans contends that the trial court made four prejudicial errors in its instructions to the jury. First, Evans argues, the court erred in instructing the jury on the application of the presumption that parties who contract for a “permanent” employment relationship intend to create merely an ordinary employment contract, terminable at the .will of either party. See Brief of Appellant at 19-20. The District Court instructed the jury as follows:
Ordinarily when an employer and an employee speak in terms of a permanent [567]*567employment relationship, the assumption is that they have in mind merely the ordinary business contract for a continuing employment, terminable at the will of either party.
You may apply this assumption if you find no evidence of the intent of Hodge and Evans to structure their employment relationship differently. In order to ascertain the parties’ intentions, you should look at such factors as the express terms of the contract as set forth by the parties, both orally and in writing, evidence of the surrounding circumstances at the time of contracting and whether there was additional consideration given, given up by Hodge other than merely agreeing to perform his job at Evans.
Tr. at 664. This instruction follows very closely the discussion of the presumption in this court’s opinion in Hodge, 707 F.2d at 1568-69. To a large extent, therefore, the validity of the District Court’s instruction is established by the doctrine of the law of the case:
When a case is appealed and remanded, the decision of the appellate court establishes the law of the case and it must be followed by the trial court on remand. If there is an appeal from the judgment entered after remand, the decision on the first appeal establishes the law of the case to be followed on the second.
IB Moore’s Federal Practice 110.404[1], at 119 (1984) (emphasis in original); see also Maggard v. O’Connell, 703 F.2d 1284, 1289 (D.C.Cir.1983) (trial court is without power to reconsider issues decided on a previous appeal).
Evans argues that because the District Court instructed the jury that “[y]ou may apply this assumption if you find no evidence of the intent of Hodge and Evans to structure their employment relationship differently,” the jury “may well have believed that if there was any evidence of such an intent, no matter how slight, it was required to find in favor of Mr. Hodge.” Brief of Appellant at 20. The court specifically instructed the jury, however, that Hodge had the burden of establishing the existence of a contract for permanent employment by a preponderance of the evidence. See Tr. at 659-60 (explaining preponderance of the evidence standard); Tr. at 663 (instructing jury that for plaintiff to carry burden of proof imposed upon him, jury must find that plaintiff and defendant “entered into a binding oral contract [and] that the terms of that agreement were clear, definite and certain, not vague, indefinite or uncertain”). Taken as a whole, the instructions correctly stated the law with respect to the interpretation of the term “permanent employment.”
Evans also asserts that the trial court erred in instructing the jury on the issue of “additional consideration.” The court instructed the jury that it could find that “additional consideration was furnished by Hodge in giving up his job in Pittsburgh and moving his family to Washington, D.C.” Tr. at 664. The court also told the jury that if Hodge established that his employment contract was intended to be permanent and that he had provided such additional consideration, then he could only be terminated for good cause. Id. Evans argues that, as a matter of law, relocation of an employee’s family or relinquishment of his previous at-will employment does not constitute “additional consideration.” See Brief of Appellant at 21-24. This argument is clearly foreclosed by the law of the case as set out in Hodge, in which this Court stated that
Hodge contends that he gave up a good job in a different city, relocated his family to a new city, and accepted employment at a lesser rate of compensation, all in reliance on Evans’ promise that his employment would be permanent. If these assertions are accepted, as they must be at this stage of the litigation, the result is a contract for employment which ... is not terminable at will even though it does not expire on some certain date in the future.
707 F.2d at 1569. The court also specifically mentioned as an example of “additional consideration” the “plaintiff’s willingness to leave a secure position in a different city in order to begin employment with defendant.” Id. The law of the case doctrine is designed to prevent relitigation of an issue [568]*568which, like this one, has already been decided in a previous appeal of the same case. See United States v. Singleton, 759 F.2d 176, 178 (D.C.Cir.1985).
Evans argues that the trial court erred in refusing to instruct the jury that Hodge had the burden of demonstrating that Til-ley possessed the authority to bind the corporation to a permanent employment contract terminable only for cause. See Tr. at 664. At trial, Evans presented testimony of a corporate official that nothing in Evans’ corporate bylaws specifically authorized Tilley to offer a permanent employment contract to an employee. See Tr. at 567-68. Evans did not submit the bylaws themselves, however.
The District Court’s refusal to give the requested instruction appears to have been correct under the law of the District of Columbia. See Newbold v. Brennan Construction Co., 48 App.D.C. 90 (D.C.), cert. denied, 248 U.S. 579, 39 S.Ct. 21, 63 L.Ed. 430 (1918), cited with approval in International Tours & Travel, Inc. v. Khalil, 491 A.2d 1149, 1154 (D.C.1985). In Newbold, the plaintiff sought to recover damages for breach of a ten-year employment contract executed by the president of the defendant corporation. The court held that “it was incumbent upon the corporation to show that [the president] did not possess the power which he assumed to exercise in executing the present contract.” Id. at 95. The Newbold court noted that the president of the corporation “looked after and controlled individually to a large extent the affairs of the corporation,” that the long-term employment contract “was not of that extraordinary nature which amounts to the conveying away of an important interest in the corporate property,” and that, as in this case, the defendant did not introduce the corporate bylaws to show lack of authority to enter into the contract. Id. at 94.
Tilley was the president and chief operating officer of Evans Financial Corporation. He made virtually all of the company’s business decisions, including decisions about the hiring and firing of employees. See Tr. at 102-03, 133. Given the evidence of Tilley’s dominant role in managing the corporation and the nature of the contract offered to Hodge, which basically amounts to an offer to employ a fifty-four-year-old man until retirement, there was no basis for requiring Hodge to prove that Tilley was expressly authorized to enter into the contract on behalf of Evans.
Finally, Evans contends that the trial court’s instruction to the jury on the issue of whether Hodge was discharged for good cause was erroneous, in that it permitted the jury to determine whether the discharge was objectively reasonable, rather than limiting the jury to determining whether Evans acted in good faith. See Brief of Appellant at 26-30. In instructing the jury on the meaning of “good cause,” the District Court stated that
[y]ou may find Hodge was discharged for good cause if you find this discharge was neither arbitrary and capricious, nor unjustified.
The firing of an employee would be arbitrary and capricious if it was done for no reason at all or for a cause not reasonably related to the employee’s performance of his duties for the employer. The firing of an employee would be unjustified if the asserted defects in the employee’s job performance did not exist or were so insubstantial or minor in character that they would not justify the employer’s action in discharging the employee.
Tr. at 665. This instruction was in accordance with the standard set out in Brock v. Mutual Reports, Inc., 397 A.2d 149 (D.C. 1979), in which the plaintiff was, like Hodge, a managerial employee alleging breach of an employment contract. The court stated in that case that an employer could justifiably dismiss “an employee who is inefficient and cannot competently perform the job for which he or she was hired,” but that “[s]light or occasional omissions do not constitute incompetent conduct justifying dismissal; thus, the proper test for determining whether an employer can be held liable for terminating an employee’s contract is whether the conduct is so inconsistent with the employer-employee relationship that it prejudices a valid [569]*569business interest of the employer.” Id. at 153. This standard requires the jury to evaluate objectively the job performance of the employee, and is basically equivalent to that set out in the District Court’s instruction.
D. The Determination of Damages
Evans argues that the jury was improperly permitted to speculate as to damages and to consider certain specific items of damages that should have been excluded. The District of Columbia Court of Appeals has set out the standard for determining damages in an action of this kind:
The measure of damages in an employee’s action against his employer for breach of the employment contract is generally the compensation “that would have been due to the employee during the unexpired period of employment with appropriate reduction to present worth.” ... This prima facie entitlement, though, is subject to the defense of mitigation of damages: “If the employee has obtained a substitute job, or could obtain one by reasonable effort, he is chargeable with the income he obtains or reasonably could obtain in this fashion, but only if the employer sustains the burden of proving these facts.”
District of Columbia v. Jones, 442 A.2d 512, 524 (D.C.1982) (quoting D. Dobbs, Law of Remedies § 12.25, at 924-25 (1973)) (citations omitted). In this case, the application of this standard was complicated by the fact that each of the parties argued for a different method of calculating what Hodge would have received had the employment contract not been breached. Hodge testified at trial that Tilley had promised him that his income at Evans (would be “equal to and greater than what I was receiving at Mellon.” Tr. at 110. Accordingly, Hodge calculated damages by estimating what he would have earned had he remained at Mellon and subtracting his actual or estimated income from Evans and from other employment sources. See Tr. at 195-203. Hodge set up a private legal practice after his discharge and estimated that the income from this private practice would equal his Evans salary after four years. For each year, he subtracted his actual or estimated private practice income from the amount he alleged that he would have been paid by Mellon. See id. Evans’ position was that Hodge was only entitled to the salary he initially received at Evans from the time his severance pay ended until the end of 1983 — apparently because Hodge stated in his deposition testimony that he would seek damages only through 1983. See Tr. at 603-05.
The District Court instructed the jury on each party’s theory with respect to the appropriate measure of damages:
Now, there are two conflicting conten: tions as to damages, and I will seek to state each of them. There are two different concepts of damages in this case. Plaintiff’s contention is that he is entitled to what he would have earned had he not been terminated, starting with the date November 7, 1981, six months after he was terminated, and when his severance pay ceased. He would project the period you are to consider into the future until his income from his private practice, as he computes it, would equal what he earned from Mellon. He uses the Mellon figure because he says Tilley promised him his income at Evans would be at least equal to the Mellon figure. This is approximately four years. From this, you will subtract whatever he has received, unemployment income, fees, et cetera. To this you would add hospitalization charges approximately $6,911. The defendant, on the other hand, contends if you reach the issue of damages, plaintiff is entitled only to what he would have earned from November 7, 1981, until the end of 1983, less unemployment income, fees, et cetera.
Tr. at 668-69. The court also instructed the jury “not to award to plaintiff speculative damages; that is, compensation for present or future detriment which although possible is remote or based on guess work.” Id. at 669.
Evans argues that the District Court’s instructions impermissibly allowed the jury to base its calculation of damages on what Hodge would have earned had he [570]*570remained at Mellon. It is apparent from the jury’s verdict, however, that it accepted Hodge’s testimony as to what occurred during his meeting with Tilley, and Hodge testified that at that meeting Tilley promised that Hodge’s compensation at Evans would equal what he was earning at Mellon. Under the standard set out in Jones, the District Court correctly permitted the jury to determine damages based on what it concluded Hodge had been promised.6
Evans also argues that Hodge “based his ‘lost income’ calculations on speculation and conjecture and thus failed to establish the amount of such damages with certainty.” Brief of Appellant at 43. To support this claim, Evans points to the fact that Hodge was allowed to estimate that he would have received a salary increase of eight percent a year if he had remained at Evans, and that his income from the private law practice would increase at the rate of thirty-three percent a year. See Tr. at 197-201. The plaintiff in a contract action “is not required to prove the amount of his damages precisely; however the fact of damage and a reasonable estimate must be established.” W.G. Cornell Co. v. Ceramic Coating Co., 626 F.2d 990, 993 (D.C.Cir.1980). Evans has not suggested any reason why Hodge’s estimates should be considered unreasonable.
Evans also objects to the trial court’s instruction that Hodge could recover medical expenses incurred after he was discharged and the medical insurance policy provided by Evans lapsed. See Brief of Appellant at 47-48. These expenses would have been covered by the insurance policy had the contract not been breached, see Tr. at 155, 165-67, and they therefore constituted consequential damages which Hodge was entitled to recover. See Maloney v. E.I. DuPont de Nemours & Co., 352 F.2d 936, 940 (D.C.Cir.1965) (plaintiff alleging wrongful breach of an employment contract is entitled to show consequential damages resulting from termination), cert, denied, 383 U.S. 948, 86 S.Ct. 1211, 16 L.Ed.2d 210 (1966).
Finally, Evans argues that the District Court erred in permitting Hodge to claim as items of damages pension and profit sharing payments he would have received had he remained at Mellon and expenses incurred in connection with the sale and purchase of houses necessitated by his move to Washington. See Brief of Appellant at 44-47. Evans correctly asserts that Hodge is not entitled to recover these items because they are not payments he would have received under the employment contract with Evans. Hodge testified that Til-ley informed him that Evans did not have a pension plan or a profit sharing plan. Tr. at 111-12. He also testified that no one at Evans promised him that he would be paid for expenses he incurred in selling his house in Pittsburgh and buying a house in Washington. Tr. at 289-90. The District Court did not refer to these items in its instructions to the jury, but it did instruct the jury to “award plaintiff ... such sum as will reasonably and fairly compensate him for the losses he has sustained,” Tr. at 669, and there is no indication that the jury did not consider these items in determining the amount of damages to be awarded to Hodge.
Nonetheless, the erroneous admission of evidence concerning improperly claimed items of damages does not require us to reverse and remand for a new trial where, as here, the amount of the jury’s verdict that might be traceable to the error can be ascertained. In these circumstances, the error may be corrected by requiring the appellee to remit the portion of the award that can be attributed to the erroneous admission of evidence. See 6A Moore’s Federal Practice ¶ 59.08[7] (1986); see also Hobson v. Wilson, 737 F.2d 1, 58 n. 159 (D.C.Cir.1984) (reviewing courts often set amount of remittitur “where the proper amount is beyond dispute”), cert. denied, 470 U.S. 1084, 105 S.Ct. 1843, 85 L.Ed.2d [571]*571142 (1985). Hodge claimed as damages the pension and profit sharing payments he would have received had he remained at Mellon, which he estimated at $6,731.75, and he also claimed $10,652 in expenses incurred in selling and purchasing his houses. Tr. at 199. Accordingly, we conclude that Hodge must be required to remit $17,-383.75 of the damages he received.
E. The Trial Court’s Treatment of Hodge as a Pro Se Litigant
Evans argues that Hodge was improperly accorded preferential treatment by the District Court because of his status as a pro se litigant. See Brief of Appellant at 30-34. Evans points to several of the court’s rulings as evidence of this alleged preferential treatment. The trial court permitted Hodge, over Evans’ objection, to introduce into evidence documents concerning Hodge’s efforts to find other employment after his discharge by Evans. See Tr. at 160-65. Evans asserts that these documents were first produced “just seven business days prior to trial,” and that Evans was “severely prejudiced” by the admission of the documents because it was unable to conduct discovery with respect to them. These documents consisted only of copies of employment advertisements to which Hodge responded and copies of letters he received in response to his inquiries. It is highly unlikely that the fact that Evans had only a week to examine them before trial could have resulted in any prejudice to Evans.7 Evans also argues that the trial court erred in refusing to allow a statement of stipulated facts to be read to the jury at the close of Evans’ case-in-chief. See Tr. at 628-29. Evans does not assert, however, that the stipulated facts were not presented to the jury through other evidence, and does not suggest any way in which the District Court’s refusal to allow the stipulations to be read to the jury hampered Evans’ ability to put on an effective defense.
III. Conclusion
Evans’ only argument which we find to have merit is its objection to the admission of evidence concerning two specific items of damages claimed by Hodge. The oral contract between Evans and Hodge was not rendered unenforceable by the District of Columbia statute of frauds, and Evans’ other challenges do not require that the verdict be overturned. Accordingly, we affirm the judgment of the District Court on condition that appellee Hodge remit $17,-383.75 of the jury’s award of damages. So ordered.
