I. INTRODUCTION
The Amoco Oil Company (“Amoco”) appeals from a jury verdict that it invaded the privacy of Thaddeus C. Pulla (“Pulla”), one of its employees, by searching his credit card records to determine if he had abused his sick leave. Amoco filed a series of post-trial motions challenging both the verdict and the jury’s award of $500,000 in punitive damages on a variety of grounds, but the district court rejected Amoco’s motions for judgment as a matter of law, a new trial and a remittitur.
Pulla v. Amoco,
II. BACKGROUND
Pulla has worked continuously for Amoco since April 14, 1974. By 1989, when he was 48 years old, Pulla had worked his way up to a class 8 supervisor of new accounts in Amoco’s credit card department. At that time, his supervisor, Robert Langois (“Langois”), judged his work to be satisfactory and noted that he was “promotable with future development.” However, on May 22, 1989, Langois told Pulla that his performance was unsatisfactory and that he might be transferred to another department. Ten days later, Pulla was asked to consider remaining in his position until age 50 at which time he could consider early retirement. On July 28, 1989, Langois demoted Pulla to a class 7 sales authorization representative. While this transfer and demotion did not reduce his pay, it did reduce his possibilities for future pay increases. Isabella Hurless, a 45 year-old, replaced Pulla as the supervisor of new accounts.
After filing an administrative complaint with the Equal Opportunity Employment Commission on March 13, 1990, Pulla filed this action on February 20,1991. He alleged that Amoco demoted and transferred him because of his age and in violation of the Age Discrimination in Employment Act (“ADEA”), 29 U.S.C. § 621 et seq., and his employment contract. To support his ADEA claim, Pulla reported that Langois made several ageist comments, including such statements as Pulla was “too old for the job,” “had been with the company too long,” and “should consider early retirement.”
Based on incidents that occurred after he filed his complaint, Pulla amended his complaint on September 9, 1992. This amendment alleged that Amoco had retaliated against him in violation of the ADEA and his employment contract and had violated state tort law by invading his privacy. The basis of the invasion of privacy claim (and the most significant alleged retaliatory action) was Amoco’s inspection of his credit card records. This alleged invasion of privacy stemmed from the action of Pulla’s co-worker, Tammy Leckband (“Leckband”). Pulla and Leck-band worked together at Amoco’s Credit Card Service Center in Des Moines, Iowa, where they handled authorizations for customer purchases and investigations of related problems. Pulla often called in sick, and over the course of 1991, he missed two months of work. Leckband was one of the employees who covered his shift when he was absent. Because she was “mad” at Pulla for what she viewed as an abuse of his sick leave, which burdened her, Leckband checked Pul-la’s personal credit card records against the days that he called in sick. In so doing, she found that Pulla had used his credit card at various restaurants and bars on days when he had called in sick. On November 8,1991, she reported these observations to Anthony Wieczorek (‘Wieczorek”), the individual who supervised her and Pulla.
Wieczorek admonished Leckband for reviewing Pulla’s credit card records, and instructed her never to repeat such behavior. She was not otherwise disciplined. After finishing this conversation with Leckband, Wieczorek asked another employee to print out this same material and gave it to Bruce Williams, an Amoco Human Resources representative, who placed this information in Pul-la’s personnel file with red marks on the days in which Pulla had called in sick. Pulla soon *653 learned that Amoco had retrieved this information, began to suffer feelings about being watched, and felt that this investigation put him in a bad light. Finally, Wieczorek referred to Pulla’s absence problem in a subsequent evaluation, and singled Pulla out for the unique requirement that he obtain a doctor’s note before submitting any claims for sick leave.
Amoco moved for summary judgment on the age discrimination claims, state law contract claims as well as the invasion of privacy claim. On January 11, 1994, the district court 1 granted summary judgment to Amoco on the state law contract claims, but ruled that a genuine dispute of materiál fact existed as to the ADEÁ and the invasion of privacy claims. Thus, Pulla’s ADEA and invasion of privacy claims were tried to a jury-
After Pulla presented his- evidence of age discrimination and invasion of privacy to the jury, Amoco requested that the district court 2 dismiss his claims as a matter of law under Fed.R.Civ.P. 50(a). ■ Amoco argued that Pulla had (1) only offered some stray comments referring to his age on his ADEA ‘ claim; (2) failed to present any evidence of retaliation based on his filing of this action; and (3) failed to establish that the search of his credit card records was “highly offensive” and “objectionable” so as to constitute an invasion of privacy.
The district court explained that it would take Amoco’s Rule 50(a) motion under advisement. However, it also noted that the invasion of privacy claim was “clearly submissive,” and that he would also allow Pul-la’s ADEA claims to go to the jury although the evidence on these claims was thin. After Pulla attempted to introduce more evidence in support of his privacy claim, and Amoco presented four additional witnesses to close out the presentation of all of the evidence, Amoco failed to renew its motion for judgment as a matter of law.
Amoco agreed to most of the jury instructions governing liability, but contended that the instruction on Amoco’s ratification of the invasion of Pulla’s privacy should not be submitted to the jury because no evidence in the record could support such a finding. Amoco also objected to submitting the punitive damages instructions to the jury on the ground that there was insufficient evidence to support those instructions. The court rejected these two objections and submitted. all of Pulla’s claims to the jury.
The jury found in favor of Amoco on the ADEA claims, but found for Pulla on the invasion of privacy claim. On the invasion of privacy claim, the jury awarded Pulla $1 in actual damages for past pain and suffering and $1 in actual damages for future pain and suffering. The jury also answered special interrogatories explaining that it found clear and convincing evidence that Amoco’s invasion of Pulla’s privacy willfully and wantonly disregarded his rights and that Amoeo’s conduct was specifically directed at Pulla. Finally, the jury awarded Pulla a total of $500,-000 in punitive damages.
On May 20, 1994, Amoco filed a series of post-trial motions, contending that, with respect to both the determination of liability and the award of punitive damages, it deserved judgment as a matter of law under Fed.R.Civ.P. 50, or in the alternative, that the court should order a new trial pursuant to Fed.R.Civ.P. 59 and remit the punitive damages award. The district court held that Amoco waived most of its claims of error, but proceeded to reject them all on the merits. In so doing, the district court engaged in the necessary post-trial review of the punitive damages award to determine whether it was excessive under Iowa law, unconstitutional *654 under the Due Process Clause, and/or should be remitted. Focusing on the potential damages arising from invasions to credit card privacy, the district court concluded that the award did not warrant a new trial nor need to be remitted. Amoco then brought this timely appeal, challenging the district court’s post-trial rulings. Pulla cross appealed, contending that the district court erroneously rejected his breach of contract claim, and that it erred by refusing to allow him to amend his complaint to conform to the evidence presented in support of a disparate impact violation of the ADEA.
III. DISCUSSION
A. AMOCO’S POST-TRIAL CHALLENGES
The district court carefully analyzed Amo-eo’s claims of error, explaining that Amoco waived most of its claims by (1) failing to move for judgment as a matter of law on that ground; (2) failing to move for judgment as a matter of law at the close of the evidence; and/or (3) failing to object to the relevant jury instruction(s). In this appeal, Amoco re-asserts four of its claims of error, the first three of which we deal with in this Section A. 3 These three claims challenge the district court’s rulings that: (1) the search of Pulla’s credit card records was sufficiently offensive so as to invade Pulla’s privacy; (2) Amoco maliciously searched Pulla’s credit card records so as to support an award of punitive damages; and (3) Amoco ratified the offensive conduct at issue. 4 The district court held that Amoco waived its first claim of error by failing to renew its motion for judgment as a matter of law at the close of all of the evidence as required by Rule 50(b), and by failing to object to the relevant jury instruction, thereby waiving its right to move for a new trial under Rule 59. 5 The court also explained that Amoco waived its second argument under Rule 50(b) by failing previously to raise it at all, and did not preserve it for a motion for a new trial by a sufficiently specific objection to a relevant jury instruction. Finally, the court held that, although Amoco had not previously objected to the sufficiency of evidence on ratification (and thus, waived its motion for judgment as a matter of law), it did preserve the issue for a Rule 59 motion by objecting to the relevant jury instruction, but that this claim of error did not warrant a new trial. 6
We concur with the district court that Amoco waived its right to file a post-trial motion for judgment as a matter of law. However, because Amoco’s motion for a new trial rested on evidentiary — as opposed to legal — grounds, .the district court erred in holding that Amoco’s failure to object properly to the relevant jury instructions waived its right to move for a new trial on two of its professed grounds but not the third. Thus, we must deal with the merits of these three grounds for a new trial. As to these three claims of error, we conclude that the district court’s denial of Amoco’s motion for a new trial did not constitute a clear abuse of its discretion.
1. Amoco’s Post-Trial Motion for Judgment As A Matter of Law
*655
Under Rule 50(b),

a litigant who fails to move for judgment as a matter of law at the close of the evidence cannot later argue — either in a post-trial Rule 50 motion or on appeal — that the verdict was supported by insufficient evidence.
Catlett v. Local 7370 of the United Paper Workers Int’l Union,
While we have never endorsed the broad exception to Rule 50(b),
10
we have previously assumed, without deciding, that we would do so.
Myers,
2. Amoco’s Motion for A New Trial
Amoco also challenged the jury’s verdict and award of punitive damages under Fed. R.Civ.P. 59, arguing that it deserved a new trial because the jury’s findings were against the great weight of the evidence so as to constitute a miscarriage of justice.
White v. Pence,
As we noted above, a litigant may move for a new trial under Rule 59 based on the overwhelming evidence contrary to the verdict without ever previously raising such an objection.
Harris v. Zurich Insurance Co.,
We have made clear that district courts enjoy broad discretion in choosing whether to grant a new trial, and thus, we accord great deference to their Rule 59 rulings.
White,
As indicated above, the district court, while ruling that there had been waivers under Rule 50(b) and also under Rule 51 except on the issue of ratification, went on to pass on the merits of the post-trial motion for judgment as a matter of law by pointing to the evidence justifying submitting the case to the jury. In light of that evidence, and after reviewing the rules that a district court must follow in ruling on motions for .new trial, the district court also denied on the merits Amoco’s motion for new trial in its entirety. We conclude that this ruling was not a clear abuse of discretion under our precedents, except insofar as the district court held that the punitive damages award did not violate the Due Process Clause of the Fourteenth Amendment.
B. PULLA’S CROSS APPEAL
Pulla argues in his cross appeal that the district court erred by (1) granting Amoco’s motion for summary judgment on his breach of contract claim; and (2) refusing to conform the pleadings to the proof so as to allow him to present a disparate impact ADEA claim to the jury. We reject each of these claims of error in turn.
1. Breach of Contract Claim
In ruling for Amoco on Pulla’s breach of contract claim, the district court concluded that Pulla failed to come forth with sufficient evidence to establish a fact issue as to whether Amoco’s employment policies constituted an exception to Iowa’s employment-at-will doctrine. The district court recognized that Iowa law provides for an exception to the employment-at-will doctrine “ “where a contract created by an employer’s handbook or policy manual guarantees an employee that discharge will occur only for cause or under certain conditions.’ ” Aplt. Addendum at 6-7 (quoting
Fogel v. Trustees of Iowa College,
Pulla contends that the evidence of an employment contract, when viewed in the light most favorable to him, created a genuine dispute of material fact. Pulla explains that a series of documents, when viewed collectively, give rise to an employment contract. Pulla suggests that several documents are particularly important in supporting a just cause requirement: (1) a progressive discipline policy that managers “should” follow; (2) a merit employment policy that managers “should” follow; (3) statements by Amoco that it will follow the law and maintain equal opportunity in employment; and (4) statements that the workplace should be friendly and cooperative. Based on our review of these statements, we concur with the district court that they were not sufficiently definite or mandatory so as to constitute a. binding contract.
See Falczynski v. Amoco Oil Co.,
2. Motion to Amend The Pleadings
At trial, Pulla contended that Amoco’s policy of not allowing non-supervisory personnel, such as himself, to apply for supervisory positions constituted a form of discrimination in violation of the ADEA. After the district court pointed out that Pulla’s pleadings did not state such a claim, Pulla moved to amend the pleadings to conform with the evidence. The court summarily denied this motion. Pulla now appeals this ruling, arguing that *658 (1) this claim fell within the pleadings under the liberal pleading standard set forth in Fed.R.Civ.P. 8; and in the alternative, (2) that the district should have allowed him to conform the pleadings to the evidence under Fed.R.Civ.P. 15(b). We reject each of these arguments in turn.
Pulla maintains that his claim that Amoco’s policy of not allowing non-supervisory personnel to apply for supervisory positions constituted a form of age discrimination (i.e., under a disparate impact theory), and thus, fell within the Rule 8’s liberal pleading standard. Pulla suggests that his claim that Amoco discriminated against him allowed him to advance any specific theory that a certain act or policy effected such discrimination. Thus, Pulla asserts that, based on his general allegation of discrimination, he could later advance the discriminatory impact theory that Amoco’s supervisor promotion policy constituted a form of age discrimination. We disagree. Pulla had the responsibility of specifically identifying the conduct challenged in his complaint in order to put Amoco on notice of the specific charges levied against it.
See Smith v. St. Bernards Regional Medical Ctr.,
Pulla also maintains that the district court abused its discretion by not allowing him to amend his pleadings to conform to the evidence under Fed.R.Civ.P. 15(b). Pulla contends that the district court’s denial of his Rule 15(b) motion constituted an abuse of its discretion under
Gamma-10 Plastics v. American President Lines, Ltd.,
C. CONSTITUTIONAL REVIEW OF PUNITIVE DAMAGES AWARD
It is clear that an award of punitive damages is subject to review to determine whether it violates principles of substantive due process, but as indicated by the plurality and other opinions filed in
TXO Prod. Corp. v. Alliance Resources Corp.,
— U.S. -,
Whether a punitive damages award is reasonable for purposes of due process, turns on: (1) the harm inflicted on the plaintiff; (2) the reprehensibility of the defendant’s conduct; (3) the likely potential harm to others arising from the complained of conduct; and (4) the wealth of the defendant.
16
TXO,
— U.S. at -,
While
TXO
upheld a 526:1 ratio of punitive to actual damages on the basis of the potential damages arising from TXO’s conduct, it explained that the potential damages must be evaluated in light of a defendant’s actual conduct. The plurality opinion underscored that the relevant inquiry looks to “ “whether there is a reasonable relationship between the punitive damages award and
the harm, likely to result
from the defendant’s conduct as well as the harm that actually has occurred.’ ”
Id.
at -,
In the instant case, the district court erred by misconceiving the nature of potential harm.
18
The district court justified the
*660
$500,000 punitive damages award by reasoning that “[w]ere
Amoco or
others similarly situated to be undeterred from intruding on the privacy of employees’ credit cards to check up on their use of sick leave or for any other purpose, the aggregate invasion of privacy into sensitive matters would be enormous indeed.”
Pulla,
The district court also erred by failing to scrutinize correctly the punitive damages award by reference to the level of the offensiveness of Amoeo's conduct. We have previously noted that the offensiveness of the conduct at issue informs the judgment as to whether a punitive damages award “‘jars one’s constitutional sensibilities.’ ”
Burke v. Deere & Company,
Finally, the district court overly discounted the effect of the limited actual harm suffered by Pulla. While the Constitution does not impose any precise formula or ratio between the amount of punitive and actual damages, the amount of punitive damages must bear “some proportion” and a “reasonable relationship” to the harm that actually
*661
occurred.

IV. CONCLUSION
We AFFIRM the denial of Amoco’s motion for a judgment of a matter of law, or in the alternative, motion for a new trial, except with respect to Amoco’s constitutional challenge to the punitive damages award. We also AFFIRM the district court’s grant of summary judgment to Amoco on Pulla’s contract law claim as well as its denial of Pulla’s motion to amend its complaint to include a disparate impact ADEA claim. Finally, as to the $500,000 award of punitive damages, we REVERSE the judgment of the district court that this award passes constitutional muster, and we REMAND this case for further proceeding consistent with this opinion.
Notes
. Harold D. Vietor, District Court Judge for the Southern District of Iowa.
. The parties consented to a trial before a United States Magistrate Judge pursuant to 28 U.S.C. § 636(c), and the case was referred to the Hon. Mark W. Bennett, who at that time was serving as a magistrate judge for the Southern District of Iowa. As Judge Bennett was appointed to the United States District Court for the Northern District of Iowa on August 30, 1994, we will refer to him and the proceedings before him as the district court. The fact that he was appointed to the Northern District of Iowa and this case arises in the Southern District of Iowa is of no moment because all judges and magistrate judges are cross-designated to preside over both districts.
Pulla,
. As explained in Section C, we sustain Amoco’s fourth claim of error: that the district court erroneously held that the punitive damages award passed constitutional muster.
. The district court carefully outlined Amoco’s various post-trial claims of error in a chart, explaining why Amoco had waived its various claims, and how the court disposed of the claims on the merits. Pulla, 882 F.Supp. at 848.
. In its post-trial motion, Amoco parcelled its challenge to the invasion of privacy verdict into three specific claims of error: (1) Pulla did not suffer the necessary level of anguish; (2) Amoco had a legitimate interest in the information; and (3) Amoco's means were not objectionable.
Pulla,
.As noted above, the district court also analyzed the substance of the claims of error waived by Amoco, and concluded that they were meritless.
. Rule 50(b) provides, in relevant part, that:
Whenever a motion for judgment as a matter of law made at the close of all the evidence is denied or for any reason is not granted, the court is deemed to have submitted the action to the jury subject to a later determination of the legal questions raised by the motion.
Fed.R.Civ.P. 50(b) (emphasis added).

See
9A Charles A. Wright & Arthur R. Miller,
Federal Practice and Procedure,
§ 2534, at 322-23 (1995); 5A James W. Moore,
Moore's Federal Practice,
1150.08, 50-84—50-85 (1995). The twin purposes of this rule are to: (1) enable the trial court to examine all of the evidence before submitting the question to the juiy; and (2) alert the opposing party to any defect in its case, thereby affording it an opportunity to cure any such defects.
Halsell v. Kimberly-Clark Corp.,
. As discussed infra, the broad exception to Rule 50(b) allows litigants, post-trial, to move for judgment as a matter of law even though they failed to file a Rule 50 motion at the close of the evidence where (1) an earlier such motion has been filed and the district court defers ruling on the motion; (2) no evidence related to the claim is presented after the motion; and (3) very little time passes between the original assertion and the close of defendant’s case.
. We acknowledge that it is a fine distinction between the exception set forth in
353 Cases,
. We note that some circuits have declined to adopt such a flexible approach, strictly construing Rule 50(b)’s requirement that objections must be filed at the close of the evidence to preserve any post-trial challenges to the verdict.
See, e.g., DeMarines v. KLM Royal Dutch Airlines,
. As noted earlier, see n. 3 supra, Amoco also set forth another ground for a new trial — i.e., the unconstitutionality of the punitive damages award — which we address in Section C.
. While Rule 51 prevents litigants from offering legal arguments in a Rule 59 motion where the litigant did not previously present those specific objections to the district court, a party need not object to the relevant jury instructions on eviden-tiary grounds in order to file a Rule 59 motion on sufficiency of the evidence grounds.
See, e.g„ Jones,
. Thus, we need not consider Amoco's argument that Iowa's exception to the employment-at-will doctrine does not extend to wrongful demotion claims.
See Zimmerman v. Buchheit of Sparta, Inc.,
. We are aware that the Supreme Court is presently considering a constitutional challenge to the amount of punitive damages awarded in
BMW of North America, Inc. v. Gore,
. While a defendant’s wealth may be taken into account in order to ensure that an award will adequately deter any future such conduct, a defendant's wealth cannot alone justify a large punitive damages award.
TXO,
- U.S. at -,
. The Court further underscored its commitment to the fact that the potential harm must he "likely,” by highlighting that West Virginia similarly imposes a likelihood requirement.
See id.
at -,
.Amoco also argues that, even if the correct conception of potential harm resulting from its conduct could support the amount of punitive damages awarded against it, that fact should not justify the award in the instant case because the juiy instructions did not specify that the jury should consider potential damages as a basis for a punitive damages award. The jury instructions in TXO, however, also did not provide that the amount of potential damages could justify a larger award of punitive damages; yet/ what the plurality considered to be substantial potential damages still played a large part in its holding that the punitive damages award passed constitutional muster. See TXO, - U.S. at -, 113 *660 S.Ct. at 2735 (O'Connor, J., dissenting). Thus, as it is arguable that TXO forecloses Amoeo’s jury instruction argument, we assume that it does, and hold for Amoco on other grounds.
. In
Burke,
we did not actually reach the constitutional inquiry because the evidence was insufficient to support any award of punitive damages, but we still noted the relationship between the offensiveness of the complained of conduct and the constitutionality of a punitive damages award. In that case, we held that the "merely objectionable" act of *'undertak[ing] a less costly alternative to remedy a perceived problem before moving to a more expensive recall program does not amount to willful or wanton conduct in disregard of the rights and safety of others” and did not suffice to support an award of punitive damages.
