{1 This case presents issues relating to the propriety of both compensatory and punitive damage awards. At the conclusion of a jury trial, defendant Price Development Company (Price), a Utah corporation now doing business as Fairfax Realty, Inc., was found liable for conversion, breach of partnership agreements, and breach of fiduciary duties. Plaintiffs Armand and Virginia Smith were awarded compensatory damages, including prejudgment interest, and punitive damages.
T2 On appeal, Price contends that (1) the trial court wrongly denied a directed verdict on the issue of whether Price's actions resulted in any damage to the Smiths; (2) the Smiths were not entitled to prejudgment interest as part of the compensatory damages; (3) the prejudgment interest award was excessive; (4) the trial court erred in submitting the issue of punitive damages to the jury; and (5) the punitive damage award was excessive. We affirm the trial court on all issues except the excessiveness of the prejudgment interest award.
BACKGROUND
T8 "On appeal, we recite the facts from the record in the light most favorable to the jury's verdict." Diversified Holdings, L.C. v. Turner,
14 Construction of the North Plains Mall was financed through a $9 million loan that was later paid with the proceeds of a $12 million loan. The mall opened in 1985 with approximately forty tenants and thereafter maintained a typical occupancy rate of 98%. Price periodically informed the Smiths that it was pleased with the performance of the mall.
15 In July 1993, Price informed the Smiths that John Price had decided to form a real estate investment trust (REIT) by pooling shopping malls and other commercial properties owned or controlled by John Price entities. Price wanted to include the North Plains Mall in the REIT and told the Smiths that if the mall were included, the Smiths would have three distinet options for handling their 15% interest in the mall.
T6 Price presented the three options to the Smiths, and the Smiths assumed they had time to consider the options and the potential transfer of the mall. Then, without further communication with the Smiths on the matter, Price proceeded to sign contribution agreements and transfer the mall property into the REIT, despite provisions in the partnership agreements that required the Smiths' consent for such transactions. 1 Preparations were then made to initiate a public stock offering in the REIT.
T7 In the ensuing months, the Smiths repeatedly requested information regarding the status of their interests in the mall, but Price failed to disclose its unilateral decision to contribute the mall property to the REIT. Instead, Price fielded the Smiths' questions regarding the three options previously given to the Smiths, leading them to believe the options were still open, even though Price knew that its unilateral action had left the Smiths with no options. When the Smiths inquired as to the possible value of their holdings should the mall be included in the REIT, Price sent various conflicting estimates, ultimately assigning a total value of just $6,160 to the Smiths' interests. In response, the Smiths presented objections and *1067 concerns as to the method used for valuing their interests, the proposed uses of proceeds from the sale of stock, and the costs that could be charged against the value of the mall. 2
T8 In April 1994, Price finally disclosed to the Smiths that Price had decided to transfer the mail to the REIT the previous September and that the three options originally presented to the Smiths were no longer available. In fact, the REIT had actually gone public on January 21, 1994, selling approximately $198,000,000 in stock. Proceeds from the public offering were used to pay existing mortgage debt on John Price properties, purchase equity interests in other property, and pay debts and expenses associated with the REIT offering. Evidence at trial showed that the overall transaction substantially benefitted John Price personally, as well as the Price Development Company.
T9 The Smiths brought suit against Price based on the foregoing events and on evidence that Price had acted in other inappropriate, self-interested ways. These other actions included the commingling of funds of multiple Price-related entities, payment of inflated management fees to a Price subsidiary, payment of interest to itself on its capital call contributions while withholding interest from the Smiths' contributions, and possible manipulation of partnership tax returns to the benefit of Price and to the detriment of the Smiths.
110 After a fourteen-day trial, the jury reached a verdict in favor of the Smiths, finding that Price had breached the partnership agreements, breached its fiduciary duty to the Smiths, and converted partnership assets. The jury awarded the Smiths $410,000 in compensatory damages, which, according to the evidence at trial, was the fair market value of the Smiths' partnership interests in the mall property at the time of the transfer. The jury added $690,000 to the compensatory amount in prejudgment interest. The jury also awarded punitive damages in the sum of $5,500,000 against Price.
1 11 Following the verdict, Price brought a number of post-trial motions, including motions for judgment notwithstanding the verdict and for new trial or, in the alternative, for a remittitur. The trial court denied these motions and entered special findings on the punitive damage award pursuant to Crookston v. Fire Insurance Exchange,
ANALYSIS
I. DENIAL OF MOTION FOR DIRECTED VERDICT
112 Price first contends that the district court should have granted its motion for a directed verdict because the Smiths' interests, it argues, were valueless outside of the REIT and Price's actions, therefore, did not result in any damage to the Smiths. "Under Utah law, a party who moves for a directed verdict has the very difficult burden of showing that no evidence exists that raises a question of material fact." Makmood v. Ross,
When reviewing any challenge to a trial court's denial of a motion for directed verdict, we review the evidence and all reasonable inferences that may fairly be drawn therefrom in the light most favorable to the party moved against, and will sustain the denial if reasonable minds could disagree with the ground asserted for directing a verdict.
Id. at ¶ 16 (citations and quotation omitted). We note here that a more complete marshal
*1068
ing of the evidence by Price would have facilitated our review of this issue. See Moon v. Moon,
1183 Price argues that had it not transferred the mall property to the REIT, the mall inevitably would have suffered bank-ruptey or foreclosure and the Smiths would have recovered nothing for their partnership interests. To this end, Price presented evidence that the mall's $12 million loan, which had been extended six times, had to be repaid by July 15, 1994. According to Price, there were insufficient resources to pay the approximately $11 million balance on the loan by this date, and foreclosure or bankruptcy was therefore imminent. Price also presented evidence that prior to the transfer, which occurred in the fall of 1998, it had made various unsuccessful attempts to refinance or sell the mall, thereby rendering the transfer to the REIT the only viable option. Price argues that this evidence demonstrates that the Smiths could not have received any value for their shares outside of the REIT. 3
1 14 The Smiths argue that financial failure of the mall was neither inevitable nor imminent. They presented evidence that the outstanding loan could have been extended again as it had been in the past and that Price's efforts to refinance or. sell the mall were not exhaustive. The Smiths also produced evidence that Price and John Price had strong financial incentives to contribute the mall to the REIT, rather than committing to sell it on the market. Finally, the Smiths used the testimony of an appraiser to show that their partnership interests had a significant fair market value.
115 Reviewing the evidence presented by each side and the inferences reasonably drawn therefrom in the light most favorable to the Smiths, we find sufficient evidence to raise a question of material fact on the issue of the mall's valuation. Reasonable minds could disagree as to whether the Smiths' interests in the mall had value outside of the REIT and therefore whether the Smiths were damaged by Price's breach of contract, breach of fiduciary duty; and conversion. Therefore, the district court appropriately denied Price's motion for a directed verdict.
IL PREJUDGMENT INTEREST
116 Price argues that the trial court improperly allowed an award of prejudgment interest in this case. "A trial court's decision to grant or deny prejudgment interest presents a question of law which we review for correctness." Cornia v. Wilcox,
T17 As established nearly a century ago in Fell v. Union Pacific Railway Co., Utah courts award prejudgment interest in cases where "damages are complete" and can be measured by "fixed rules of evidence and known standards of value."
[ 18 Some jurisdictions apply the rule that a fiduciary who breaches his duties should not be allowed to benefit from his misconduct and therefore must account for interest on any money or property the fiduciary misappropriated. 4 Following this principle, the tri *1069 al judge instructed the jury that if Price were found liable for breach of fiduciary duty, the Smiths would be entitled to an interest award measured from the date of the breach. ' ’
1 19 This court has never decided whether to adopt the principle that prejudgment interest is always appropriate in breach of fiduciary cases. We need not make the decision in this case, however, because we find that the prejudgment interest awarded was appropriate under the Fell standard.
[7] 120 In Fell, this court stated:
The true test to be applied as to whether interest should be allowed before judgment in a given case or not is, therefore, not whether the damages are unliquidated or otherwise, but whether the injury and consequent damages are complete and must be ascertained as of a particular time and in accordance with fixed rules of evidence and known standards of value, which the court or jury must follow in fixing the amount, rather than be guided by their best judgment in assessing the amount to be allowed for past as well as for future injury, or for elements that cannot be measured by any fixed standards of value.
121 This court concluded, in two of the first cases interpreting Fell, that fair market valuations of real property are within the category of damages upon which prejudgment interest may properly be awarded. See San Pedro, Los Amgeles & Salt Lake R.R. Co. v. Bd. of Educ.,
122 Similarly, in the present case, damages resulted from the loss of plaintiffs' interest in a piece of real property-the North Plains Mall-and assessing the amount of loss involved a fair market valuation of the property. Hence, the language from San Pedro is applicable:
We, therefore, have a case in which, for the purpose of fixing damages, the injury is complete; the damages are ascertained by the ordinary rules of evidence and according to a known standard or measure of value. And all this must be determined from competent evidence, which is binding *1070 upon both the court and jury. The jury, therefore, only had a right to exercise their judgment within the limits of the evidence upon the question of value. It is not a case where it was left to the jury to determine the amount of damages from a mere description of the wrongs done or injuries inflicted whether to person, property or reputation.
123 Where, as here, damages were complete as of the day the property was transferred to the REIT and the jury based its award of damages on competent testimony from an appraiser who used generally accepted principles in determining the market value of the real property, an award of prejudgment interest is appropriate. The fact that the parties disputed the value of the property at trial does not change our conclusion that the jury's determination of the property's value was "ascertained ... in accordance with fixed rules of evidence and known standards of value." Fell,
III. EXCESSIVENESS OF THE PREJUDGMENT INTEREST AWARD
124 Having upheld the trial court's decision to award prejudgment interest, we now decide whether the trial judge erred in denying a new trial or remittitur on the amount of prejudgment interest awarded. Following the jury's verdict, Price attacked the compensatory award under rule 59(a)(5) and (6) of the Utah Rules of Civil Procedure, contending that the prejudgment interest component of the compensatory award was excessive and not supported by the evidence presented at trial. Under rule 59(a), a trial judge may grant a new trial or remittitur of damages when, inter alia, there are "[e}xces-sive or inadequate damages, appearing to have been given under the influence of passion or prejudice," or there is an "[iJnsuffi-ciency of the evidence to justify the verdict or other decision." Utah R. Civ. P. 59(a)(5)-(6) (2003); see also Crookston v. Fire Ins. Exch,
125 We apply an abuse of discretion standard in reviewing a trial judge's decision to grant or deny a new trial or remittitur on the amount of compensatory damages. Crookston,
$26 Through the use of an expert witness, the Smiths presented detailed interest calculations at trial reflecting an interest amount due of $597,221. The interest rate used by the Smiths' accounting expert to calculate the interest due the Smiths was apparently derived from the partnership agreements. See Utah Code Ann. § 15-1-1(2) (2002) (setting the legal interest rate at 10% per annum or, alternatively, any rate agreed upon by the parties). The jury, however, awarded $690,000 in prejudgment interest. 9 Because we find no evidence in the *1071 record to support the jury's addition of nearly $100,000 to the figures calculated by the Smiths' expert, we hold that the trial court's denial of remittitur constituted an abuse of discretion. Accordingly, we remit the prejudgment interest award to $597,221. 10
IV. SUBMISSION OF PUNITIVE DAMAGES TO THE JURY
T27 Price contends that the district court erred in submitting the option of punitive damages to the jury. In Utah, punitive damages are available only upon clear and convincing proof of "willful and malicious or intentionally fraudulent conduct, or conduct that manifests a knowing and reckless indifference toward, and disregard of, the rights of others." Utah Code Ann. § 78-18-1(1)(a) (2002); Behrens v. Raleigh Hills Hosp., Inc.,
128 Having reviewed the record in the light most favorable to the Smiths, we find that there is more than sufficient evidence to support the court's submission of the punitive damages question to the jury. 11 Price's actions display an intentional disregard of the Smiths' rights and of its fiduciary obligations. The court thus appropriately allowed the jury to evaluate the evidence and determine whether punitive damages were merited.
V. EXCESSIVENESS OF THE PUNITIVE DAMAGE AWARD
€29 Price also challenges the punitive damage award for excessiveness, although the legal basis for Price's challenge is somewhat unclear. The Smiths argue that Price has not explicitly challenged the award on constitutional grounds and that our review of the award should therefore be limited to the issue of whether the trial judge abused his discretion in denying Price's motion for a new trial under rule 59(a)(5) of the Utah Rules of Civil Procedure on the basis that the punitive damages awarded were excessive. In response, Price argues that it has, in fact, mounted a constitutional challenge to the award and that, in any event, this court must conduct a de novo review of the exces-siveness of the award.
130 Although Price characterizes its challenge to the award of punitive damages as a federal constitutional challenge, Price did not brief the factors that the United States Supreme Court has enunciated for evaluating whether an award of punitive damages is excessive under the Due Process Clause of the U.S. Constitution. See BMW of N. Am., Inc. v. Gore,
*1072
T{381 Although we evaluate the excessiveness of the punitive award under the Crook-ston factors, we note that the Crookston factors share at least some similarities with the Gore factors, which are used in evaluating a federal constitutional challenge. See infra notes 13 and 16 and accompanying text. We note also that this court has adopted a de novo standard for reviewing jury and trial court conclusions under the Crookston factors. See Diversified Holdings,
132 In Crookston, this court enunciated seven factors to be analyzed in evaluating whether a punitive damage award is excessive:
(1) the relative wealth of the defendant; (i) the nature of the alleged misconduct; (i) the facts and circumstances surrounding such conduct; (iv) the effect thereof on the lives of the plaintiff and others; (v) the probability of future recurrences of the misconduct; (vi) the relationship of the parties; and (vii) the amount of actual damages awarded.
A. The Relative Wealth of Price
1 33 We first consider Price's wealth.
Our cases have determined that a defendant's wealth can be either an aggravating or a mitigating factor in determining the size of a punitive damage award, since punitive damages should be tailored to what is necessary to deter the particular defendant, as well as others similarly situa-ated, from repeating the prohibited conduct.
Diversified Holdings,
$34 Price Development Company was a large owner and operator of commercial shopping malls and retail properties in the intermountain states. Its chairman and CEO, John Price, owned 99.99% of the company. In the court below, Price Development Company's total wealth was found to be in excess of $37 million. This amount was determined after attempting to overcome the obstacles associated with commingled funds and the highly interrelated ownership and operations of various John Price entities, *1073 each of which had substantial assets. With Price Development Company valued at $37 million, the $5.5 million punitive damage award represents approximately 15% of the company's wealth. An analysis of the remaining Crookston factors will aid us in determining whether this percentage renders the award excessive under the facts of this case.
B. The Nature of Price's Misconduct
135 This factor requires us to analyze Price's misconduct in terms of "mali-clousness, reprehensibility, and wrongfulness." Campbell I,
136 In this case, the jury found Price liable for breach of its fiduciary duty to the Smiths, breach of partnership agreements, and conversion of partnership assets. Along with the verdict, the trial court entered special findings stating that "the jury could have found by clear and convincing evidence a pattern of deceit, failure to disclose and misrepresentation." In particular, the court detailed Price's prolonged, deliberate failure to inform the Smiths of the execution of the contribution agreements and the resulting unavailability of the three options that Price originally gave the Smiths regarding how their interests could be handled in the REIT transaction. The court also detailed Price's conflicting and "intentionally misleading" calculations of the value of the Smiths' interests in the mall property in the REIT. The caleu-lations given to the Smiths differed significantly from the company's own calculations, which the company did not reveal until six years of litigation had ensued. Additionally, the court detailed Price's acts of financial misconduct, including payment of excessive fees to itself as general partner, commingling funds from different Price-owned properties, and accruing interest to itself on its own capital contributions while denying the Smiths interest on their contributions.
T37 We agree with the trial court that Price's actions amount to affirmative misconduct showing deliberate misrepresentation and disregard of the rights of the Smiths. Price's actions accordingly support a substantial award of punitive damages.
C. Facts and Circwmstances Surrounding Price's Misconduct
(38 "This factor looks to the circumstances surrounding the illegal conduct, particularly with respect to what the defendant knew and what was motivating his or her actions." Campbell I,
1139 Price argues that the motivation for its actions was to benefit the Smiths and everyone involved in the REIT transaction. *1074 Price also reasserts that its actions were necessary to save the mall from foreclosure. However, the evidence presented at trial (and not fully marshaled by Price in its brief) was that Price, John Price, and the Price-related entities making up the general partnership all had significant financial incentives to carry out the REIT transaction. These incentives included repayment to Price of $27 million of loans made to the Price-related malls, acquisition of stock holdings in the REIT, elimination of $94 million of John Price's personal guarantees on existing loans for the mall and other properties, and deferral of federal income tax consequences.
T 40 With respect to Price's failure to disclose its dealings with the partnership property to the Smiths, Price asserts without elaboration that it avoided responding to the Smiths' inquiries on the advice of legal counsel. As noted by the trial court, substantial evidence was presented at trial that Price did not want the Smiths to interfere with the REIT's formation by filing an adverse claim or a lawsuit prior to January 1994 when the REIT went public Thus, Price's self-interested actions, made in the face of known fiduciary obligations, support a substantial punitive damage award.
D. Effect of Price's Misconduct on the Smiths and Others
T 41 This factor requires us to analyze the actions of Price in terms of their impact on the Smiths and others. Price's misconduct caused the Smiths to lose their partnership interests in the mall. Although this loss was significant, it does not appear from the evidence that it had a "devastating impact" on the Smiths. Nor did Price's actions have a "widespread effect on groups of vulnerable victims." Diversified Holdings,
E. Probability of Future Recurrences
(42 "This factor analyzes the likelihood that the defendant will repeat or continue engaging in its wrongful behavior. A high probability of recidivism justifies a higher than normal punitive damage award." Campbell I,
F. Relationship of the Parties
143 "This factor analyzes the relationship between the parties, looking particularly at the degree of confidence and trust placed in the defendant." Campbell I,
T44 Price failed as a fiduciary to deal fairly with the Smiths and their partnership interests. The trial court noted in its special findings that, in addition to other inappropriate actions, Price failed to advise the Smiths of the potential conflicts of interest it had in forming the REIT with other Price-related entities. Price also disregarded the consent clause in the partnership agreements which, according to testimony in the record, was drafted in recognition of the Smiths' valnera-bility within the partnership structure. The *1075 Smiths rightly expected a greater degree of candor and loyalty than they received. This factor weighs strongly in favor of a substantial punitive damage award.
G. Ratio of Punitive to Compensatory Damages
1 45 The ratio of punitive to compensatory damages is the final factor for our consideration. This court has not established an absolute ceiling for the ratio of a damages award,
16
and a high ratio is not by itself determinative of excessiveness. Diversified Foldings,
(46 The United States Supreme Court recently scrutinized punitive damage awards under federal due process standards. State Farm Mut. Auto. Ins. Co. v. Campbell,
1 47 In the present case, the jury awarded the Smiths $5.5 million in punitive damages and $1.1 million in compensatory damages, producing a 5 to 1 ratio. We have already reduced the compensatory award, however, to $1,007,221 by remitting the amount awarded as prejudgment interest. The ratio resulting from this reduction is approximately 5.5 to 1, well within the single-digit ratio discussed by the Supreme Court in Campbell IL.
48 Having concluded our assessment of the case under the Crookston factors, we find that Price's intentionally deceptive business dealings with individuals to whom it owed a fiduciary duty were sufficient to support a $5.5 million punitive damage award. We therefore uphold the punitive damages as awarded by the trial court. We believe that the evidence in the record and our overall analysis support an award of this amount as a serious reprimand for Price's actions to deter future misconduct.
CONCLUSION
[ 49 We affirm (1) the trial court's denial of a directed verdict in Price's favor, (2) the trial court's decision to award prejudgment interest (on alternate grounds), (8) the trial court's submission of the issue of punitive damages to the jury, and (4) the jury's award of $5.5 million in punitive damages. We remit the award of prejudgment interest from $690,000 to $597,221 to more accurately reflect the evidence presented by the Smiths' accounting expert at trial. The Smiths are further entitled to an award of reasonable costs and attorney fees as required by the partnership agreements. We remand to the *1076 district court for a determination of the proper amount of the award. 18
Notes
. The partnership agreements required 90% approval of the limited partners before Price, as the general partner, could assign the property for a '"mnon-partnership purpose." The Smiths held 15% and presented evidence at trial that conveyance of the property into the REIT was not a partnership purpose under the agreement. Price has not contested this point on appeal.
. Price proposed that $48 million of the money to be raised from the sale of stock in the REIT be used to buy out partnership interests in another mall, with a portion of that expense charged to the North Plains Mall. In addition, approximately $722,000 in {ees incident to the formation of the REIT was to be charged against the value of the mall. The Smiths objected to these items and also contested the use of a "REIT value"-rather than fair market value-for valuing their interests in the mall.
. Price uses the case of Mahmood v. Ross,
. See, eg., Josephson v. Marshall,
. In later Utah cases, the test has been recited as follows:
Where the damage is complete and the amount of the loss is fixed as of a particular time, and that loss can be measured by facts and figures, interest should be allowed from that time ... and not from the date of judgment. On the other hand, where the damages are incomplete or cannot be calculated with mathematical accuracy, such as in the case of personal injury, wrongful death, defamation of character, false imprisonment, etc., the amount of the damages must be ascertained and assessed by the trier of fact at the trial, and in such cases prejudgment interest is not allowed.
Cornia,
. Utah Code Ann. § 78-27-44 (2002) creates a statutory right to prejudgment interest on special damages in personal injury cases.
. Two Utah Court of Appeals decisions have held that fair market valuations are too "inherently uncertain" to support prejudgment interest awards. Klinger v. Kightly,
. _" '[Wle may affirm a trial court's decision on any proper ground(s), despite the trial court's having assigned another reason for its ruling.' " Gibbs M. Smith, Inc. v. United States Fid. & Guar. Co.,
. We note that in many cases, where the interest rate to be applied is straightforward and the necessary calculations are free of factual complexity, the amount of prejudgment interest to be awarded may be a question reserved for, and entered by, the trial judge instead of the jury. In *1071 this case, the partnership agreements set a floating rate dependent upon the prime rate calculated by a particular bank and adding two percentage points, which was apparently the rate used by the Smiths' expert in his calculations. Because the determination of such a rate requires factual inquiry, the interest calculations in this case were appropriately treated as a matter open to evidence.
. Courts may offer a remittitur of damages as an alternative to a new trial. The party against whom the rule 59(a) motion is brought may either accept the amount of damages that the court considers justified or submit to a new trial on the issue. See Crookston,
. See Background, supra, and part V, infra.
. This court is not obligated to address issues that are not adequately briefed. State v. Gomez,
. In Campbell I, this court adopted a de novo standard of review for reviewing whether punitive damages are excessive under state law (the Crookston analysis). This was done apparently as a maiter of judicial economy, see Campbell I,
. The Crookston factors that consider the nature of a defendant's misconduct, the facts and circumstances surrounding the defendant's misconduct, and the probability of future recurrences (recidivism) are subsumed in the "reprehensibility" guidepost established in Gore as part of the federal punitive damage excessiveness analysis. See Gore,
. "Behaviors that undermine the efficiency and integrity of the judicial process may also be considered under the rubric of the second [Crook-ston] factor." Diversified Holdings,
. "[Sltrict dollar amount, percentage of defendant's wealth, and ratio ceilings would allow potential defendants to calculate their exposure to liability in advance, thus diminishing the deterrent effect of punitive damages." Crookston,
. The ratio of punitive to compensatory damages is the second guidepost within the {federal Gore analysis.
. The trial court awarded the Smiths reasonable costs and attorney fees pursuant to the terms of the partnership agreements, which provide: "In the event of any legal proceeding involving the interpretation or enforcement of the rights or obligations of the Partners hereunder, the prevailing party or parties shall be entitled to recover its reasonable attorneys' fees and costs." The Smiths have requested costs and attorney fees incurred in this appeal, and Price has not challenged the request. We therefore award the Smiths reasonable attorney fees and costs for this appeal.
