Opinion
HUFFMAN, J.
California Commerce Bank (CCB) appeals a judgment following a jury verdict finding it liable for (1) 25 percent of the damages suffered by Wisper Corporation N.V. (Wisper) caused by CCB’s negligence in dealing with Edgar Benitez (Benitez), an employee of Wisper who diverted proceeds of Wisper’s checks through an account he opened with [952]*952CCB, and (2) conversion of one check payable to International Investments Corporation (International). CCB contends on appeal: (1) CCB is not liable to Wisper because Benitez was listed as an alternate payee on most of the checks diverted by Benitez; (2) equitable estoppel applies to bar International’s claim; (3) the Code of Civil Procedure2 section 339, subdivision 1 two-year statute of limitations applies to bar Wisper’s claim for most of the check proceeds diverted by Benitez; (4) CCB is entitled to a setoff for amounts paid by Benitez to Wisper; (5) the court erred by awarding Wisper postjudgment interest from the date of the verdict rather than from the date of entry of judgment; (6) the court erred by denying a motion for costs filed by Banco Nacionale de Mexico, Banamex USA and Banamex Holding Company (collectively Banamex), which on Wisper’s motion were dismissed as defendants; and (7) Wisper’s claim is barred by its “unclean hands.”
Wisper and International cross-appeal the judgment contending: (1) CCB is liable for conversion of all the checks diverted by Benitez because as a matter of law they were paid on a forged endorsement; (2) the court erred by instructing the jury regarding endorsements; (3) CCB is liable for conversion of those checks on which it purportedly supplied Wisper’s endorsement; (4) CCB is liable for conversion of three checks which did not include Benitez’s name; (5) Wisper’s judgment against CCB should not have been reduced by its own comparative negligence; and (6) the court erred by denying Wisper’s request for prejudgment interest.
Higgs, Fletcher & Mack (Higgs), attorney for CCB, appeals an order imposing sanctions against it for discovery abuse, contending the court abused its discretion.
We agree that postjudgment interest should apply from the date of entry of the judgment and not the date of the verdict, and that Banamex should have been awarded its costs as a prevailing party. We disagree with all other contentions. Accordingly, we affirm the judgment in part and reverse it in part and remand for further proceedings, and we affirm the order imposing sanctions.
Factual and Procedural Background
The Rivera-Torres family purchased the Colony Club apartment complex in Orlando, Florida. Epoch Management, Inc. (Epoch) was hired to manage [953]*953the complex. The complex ultimately became owned by Wisper, the stock of which was owned by Carlos, Mauricio and Alberto Rivera-Torres.3
The Rivera-Torres family retained Scott Aurich (Aurich), a commercial real estate broker, to oversee the management of many of its real estate holdings. Aurich opened an office in San Ysidro and advertised for a bookkeeper or accountant to prepare financial statements, reconcile bank accounts and help Aurich oversee the operations of the United States properties. Benitez responded to the advertisement. He spoke fluent Spanish and gave Aurich references. Aurich hired Benitez. Benitez did not disclose to Aurich that he recently had been convicted of embezzling checks from a former employer. Although Aurich knew Benitez was in jail for approximately a month shortly after he was hired and Benitez’s daughter told Aurich that Benitez had been convicted of driving while under the influence of alcohol or driving with a suspended license, Aurich did not confirm this information with either the court or the jail. Carlos Rivera-Torres also was aware of Benitez’s jail term and loaned Benitez $6,000 for bail money.
Benitez’s duties included receiving from Epoch checks from the operations of the Colony Club complex, which typically exceeded $50,000 per month. Benitez was responsible for depositing the checks received from Epoch into Wisper’s existing account with the Bank of America. Benitez had a rubber endorsement stamp which read “For Credit Account of Wisper Corp. N. #13884-01625,” apparently identifying Wisper’s account number with the Bank of America. Benitez did not have any authority to withdraw money from Wisper’s Bank of America account. Using Epoch’s monthly financial statements and bank account statements from the Bank of America, Benitez also prepared financial statements which were given to Wisper’s outside accounting firm for preparation of tax returns. Benitez also prepared financial statements for International.
After CCB’s solicitation of the Rivera-Torres family’s banking business, Carlos Rivera-Torres opened a personal account with CCB; Anibac, another Rivera-Torres family corporation, later opened a corporate account with CCB, based on the written authority of two of its officers, Carlos Rivera-Torres and Angel Lizardi. At a dinner meeting, Carlos Rivera-Torres introduced Benitez to several CCB officers.
On April 21, 1989, Benitez opened an account in the name of “Wisper Corporation, N.V.” at the San Ysidro branch of CCB. Elizabeth Fimbres (Fimbres), CCB’s customer service representative for new accounts, opened [954]*954the account. Fimbres typed a signature card and corporate resolution form, naming Benitez as the only officer of Wisper and the only signatory for the account. In Fimbres’s presence, Benitez signed both documents representing himself as an officer of Wisper and as the only signatory named by Wisper’s board of directors. Benitez provided no documentation to Fimbres or CCB verifying his authority to act on behalf of Wisper. Benitez merely delivered to Fimbres a translated copy of Wisper’s articles of incorporation, which did not identify any of Wisper’s shareholders, directors or officers, and did not name Benitez in any capacity.4
Beginning in April 1989 and continuing through August 1991, Benitez deposited into the new CCB account 28 checks received from Epoch and later withdrew those funds on his own signature and for his own benefit.5 Epoch made 24 of the 28 checks payable to “Wisper Corp NV/E. Benitez” or variations of that payee designation. Benitez typically used a rubber endorsement stamp (presumably the Bank of America stamp altered to delete the account number) to endorse the checks “For Credit Account of Wisper Corp. N.” At the time of deposit, CCB’s employees typically would write the account number for CCB’s Wisper account opened by Benitez (i.e., 32013880-01) below the stamped endorsement.
Alejandro Rivera-Torres was responsible for supervising the financial affairs of the Rivera-Torres family interests, including Wisper, and he received monthly reports from Epoch showing Wisper’s net receipts from the Colony Club complex which should have been deposited monthly in Wisper’s account with the Bank of America. He also received regular summaries of the balance in Wisper’s account with the Bank of America. However, despite this available information, he never noticed Benitez’s diversion of money from Wisper over the two-year period.
On May 8, 1992, Wisper and International filed a complaint for damages against CCB, Banamex and Union Bank, asserting causes of action for negligence and mistake.6 Wisper sought damages of at least $1,399,132.83 against CCB and Banamex, and International sought damages of at least $11,820.33 against CCB and Banamex. The court denied CCB’s motion for summary adjudication regarding 24 checks. The court rejected CCB’s argument that because Benitez was the alternate payee on those 24 checks no cause of action could be stated against it. The court also rejected CCB’s [955]*955motion in limine to exclude claims for checks diverted before May 8, 1990, rejecting CCB’s argument that the section 339 two-year statute of limitations applied. The court found the section 338 three-year statute of limitations applied with the time period commencing on discovery of the facts constituting the cause of action. During the course of the trial, Wisper’s motion to dismiss Banamex as a defendant was granted. At close of trial, the court granted Wisper’s motion to amend its complaint to include a cause of action against CCB for conversion.
On June 29, 1993, the jury found by special verdict that check No. 2219 made payable to International in the amount of $11,820.33 was “paid on a forged endorsement” and that CCB did not “act in good faith, and in accordance with reasonable commercial standards, in paying Check No. 2219.” The jury further found CCB was negligent and its negligence was a cause of damage to Wisper. It also found Wisper was negligent and its negligence contributed as a cause of its own damage. The jury found the total amount of damages suffered by Wisper and International was $1,445,953.60. The jury attributed 75 percent of the negligence to Wisper and the remaining 25 percent to CCB. On September 22, 1993, the court entered judgment against CCB (1) for International in the amount of $11,820.33 plus 7 percent interest from November 23, 1990, through June 29, 1993, and at the legal rate thereafter until paid, and (2) for Wisper in the amount of $358,533.32 plus interest from June 29, 1993, until paid. The judgment noted that Wisper’s amount represented the total amount of damages found by the special verdict less the $11,820.33 amount for International, multiplied by CCB’s 25 percent proportionate liability for its negligence. The court also awarded Wisper and International their costs of $7,334.88. The court initially awarded Banamex its costs, but later granted Wisper’s motion to tax those costs. The court denied Wisper’s motion for prejudgment interest.

The Two-year Statute of Limitations of Section 339, Subdivision 1 Does Not Apply to Bar Wisper’s Claim
CCB contends the section 339, subdivision 1 two-year statute of limitations applies to bar Wisper’s claim. We disagree.
[956]*956The court ruled that the three-year statute of limitations, accompanied by delayed discovery, applied to Wisper’s action against CCB. In its ruling the court cited Sun ’n Sand, Inc. v. United California Bank (1978) 21 Cal.3d 671 [148 Cal.Rptr. 329, 582 P.2d 920] (hereafter Sun ’n Sand). In Sun ’n Sand the California Supreme Court held that the section 338, subdivision 3 three-year statute of limitations applied to an employer’s negligence action against a bank for negotiating a number of checks forged or altered by an employee. (21 Cal.3d at pp. 678, 697-698.) The court stated: “Our strong policy favors fault-based liability; negligent tortfeasors must compensate persons injured by their failure to exercise ordinary care. [Citations.] The rules governing negligence actions—including the normally applicable three-year statute of limitations of Code of Civil Procedure section 338, subdivision 3—should not be varied so as to diminish fault-based liability absent a clear and specific legislative directive.” (Id. at p. 698, fii. omitted.) In a footnote to that statement, the court noted: “The three-year statute of limitations applies to recovery for injury to property; for different reasons of policy, the limitations period for negligence actions based on personal injuries is one year. (Code Civ. Proc., § 340, subd. 3.)” (Id. at p. 698, fn. 22.)
In 1988, section 338, subdivision 3 was renumbered as section 338, subdivision (c), and it provided at the time of Benitez’s diversions that a three-year limitations period applies to an “action for taking, detaining, or injuring any goods or chattels, including actions for the specific recovery of personal property. . . .” In contrast, section 339, subdivision 1 provided at the time of Benitez’s diversions that a two-year limitations period applies to an “action upon a contract, obligation or liability not founded upon an instrument of writing . . . .” CCB’s sole authority in support of its contention that the shorter two-year section 339, subdivision 1 limitations period applies to bar Wisper’s claim is an ambiguous observation by one secondary authority: “[While it primarily governs oral contracts, section] 339(1) also governs actions based on negligent wrongs not involving injuries to person or real or tangible personal property; e.g., negligent performance of professional services. [Citations.]” (3 Witkin, Cal. Procedure (3d ed. 1985) Actions, §440, pp. 470-471.) However, neither that authority nor any other authority cited by CCB states that section 339 applies to actions involving checks or other negotiable instruments. In fact, CCB concedes in its appellant’s opening brief that Sun ’n Sand “involved a material alteration of checks by an employee. Thus, personal property had been injured, and the action was brought within the language of [section] 338, subdivision (3) [now section 338, subdivision (c)].” Sun ’n Sand involved a negligence action against a bank for its negotiation of forged checks by an employee, and the case at hand involves a negligence action against CCB for, inter alia, its opening of an account in the name of Wisper which allowed Benitez to [957]*957divert checks away from Wisper. We nevertheless conclude the two cases are apposite, and any distinction CCB may attempt to make is a distinction without a difference.
Under our “primary rights” theory, we look to the injury or “harm suffered” in defining a particular “cause of action.” Here, as in Sun ’n Sand, the “harm suffered” was the diversion of checks that were the property of the employer. Thus, the cause of action in each is one for injury to personal property consisting of checks. Other courts have recognized that checks constitute personal property subject to the limitations period of section 338, subdivision 3 (now section 338, subdivision (c)). (See, e.g., Bank of America v. Security Pacific Nat. Bank (1972) 23 Cal.App.3d 638, 642 [100 Cal.Rptr. 438]; Fabricon Products v. United Cal. Bank (1968) 264 Cal.App.2d 113, 117 [70 Cal.Rptr. 50]; Commercial Cotton Co. v. United California Bank (1985) 163 Cal.App.3d 511, 515 [209 Cal.Rptr. 551, 55 A.L.R.4th 1017].) Further, to the extent this action is viewed as one for the return of specific money, our California Supreme Court has recognized that section 338, subdivision 1 would apply. (Minsky v. City of Los Angeles (1974) 11 Cal.3d 113, 119, fn. 6 [113 Cal.Rptr. 102, 520 P.2d 726].)
CCB also contends the court erred by ruling that delayed discovery would apply to delay the running of the three-year limitations period. Benitez opened the CCB account in the name of Wisper on April 21, 1989. Before May 8, 1989, he deposited only one check into that account (i.e., check No. 3463 dated April 5, 1989, in the amount of $50,206.12 was deposited on April 25, 1989). The next check was not deposited until May 9, 1989. Because Wisper’s complaint was filed on May 8, 1992, delayed discovery applied only to the first check deposited by Benitez and delayed the running of the statute of limitations by only two weeks. Based on the record, we cannot conclude the court erred by impliedly finding that Wisper could not have become aware of this diversion through the exercise of reasonable diligence within a two-week period. (See, e.g., Leaf v. City of San Mateo (1980) 104 Cal.App.3d 398, 408 [163 Cal.Rptr. 711].) We conclude Wisper’s action was not barred by the applicable statute of limitations.

Wisper Is Not Entitled to Prejudgment Interest
Wisper contends it is entitled to prejudgment interest pursuant to Civil Code section 3287, subdivision (a) (hereafter Civil Code section 3287), [958]*958which provides in part: “Every person who is entitled to recover damages certain, or capable of being made certain by calculation, and the right to recover which is vested in him upon a particular day, is entitled also to recover interest thereon from that day . . . .” The damages under the facts of this case were not “certain” or “capable of being made certain by calculation,” and we conclude Wisper is not entitled to prejudgment interest.
Civil Code section 3287 was originally enacted in 1872. Its application to actions other than contract actions, such as tort actions, is well established. (Marine Terminals Corp. v. Paceco, Inc. (1983) 145 Cal.App.3d 991, 995 [193 Cal.Rptr. 687].) When Civil Code section 3287 was “adopted in 1872, the key distinguishing factor was not . . . whether the cause of action arose in tort or contract, but rather whether the damages were readily ascertainable.” (Levy-Zentner Co. v. Southern Pac. Transportation Co. (1977) 74 Cal.App.3d 762, 795 [142 Cal.Rptr. 1].) The Levy-Zentner court held that a trial court erred in concluding Civil Code section 3287 could not apply to award prejudgment interest “in tort actions for damage to real or personal property.” (Levy-Zentner, supra, at p. 798.) Furthermore, a defendant’s denial of liability does not make damages uncertain for purposes of Civil Code section 3287. (Stein v. Southern Cal. Edison Co. (1992) 7 Cal.App.4th 565, 572 [8 Cal.Rptr.2d 907]; Marine Terminals Corp. v. Paceco, Inc., supra, 145 Cal.App.3d at p. 995.) As one court stated: “Damages are deemed certain or capable of being made certain within the provisions of subdivision (a) of [Civil Code] section 3287 where there is essentially no dispute between the parties concerning the basis of computation of damages if any are recoverable but where their dispute centers on the issue of liability giving rise to damage.” (Esgro Central, Inc. v. General Ins. Co. (1971) 20 Cal.App.3d 1054, 1060 [98 Cal.Rptr. 153].) As provided by common law before it, Civil Code section 3287 mandates an award of prejudgment interest where “ ‘the amount of the plaintiff’s claim’ ” can be determined by established market values or by computation. (Levy-Zentner Co. v. Southern Pac. Transportation Co., supra, at p. 795.) Thus, it is clear that Civil Code section 3287 looks to the certainty of the damages suffered by the plaintiff, rather than to a defendant’s ultimate liability, in determining whether prejudgment interest is mandated. An award of prejudgment interest is intended to make the plaintiff whole “for the accrual of wealth which could have been produced during the period of loss.” (Cassinos v. Union Oil Co. (1993) 14 Cal.App.4th 1770, 1790 [18 Cal.Rptr.2d 574].)
CCB asserts, however, that Civil Code section 3287 cannot apply in a comparative negligence case because a defendant does not know the amount of damages that ultimately will be awarded against it. CCB does not cite, and we are unable to locate, any authority holding that Civil Code [959]*959section 3287 does not apply in a comparative negligence case. Accordingly, we consider this question to be one of first impression. Although CCB concedes that in a comparative negligence case the trier of fact “apportion[s] liability between the plaintiff and defendant,” CCB asserts it could not know what the apportioned damage award against it could be until a verdict is delivered. (Original italics.)
Prior to 1975, Civil Code section 3287 required an award of prejudgment interest in any negligence case in which a plaintiff’s damages were certain or capable of being made certain by calculation. (See, e.g., Levy-Zentner Co. v. Southern Pac. Transportation Co., supra, 74 Cal.App.3d at pp. 796-799.) Pre-1975 negligence cases applied the “all-or-nothing” contributory negligence system; the defendant would be liable for either all or none of the plaintiff’s damages. Therefore, given certain damages suffered by a plaintiff, the only issue disputed would be the defendant’s liability for those damages. If the defendant were found liable, then the plaintiff would be entitled to Civil Code section 3287 prejudgment interest.
In 1975 the California Supreme Court replaced the contributory negligence system with the “pure” comparative negligence system. (Li v. Yellow Cab Co. (1975) 13 Cal.3d 804, 828-829 [119 Cal.Rptr. 858, 532 P.2d 1226, 78 A.L.R.3d 393].) The “fundamental purpose” of the pure comparative negligence system is “to assign responsibility and liability for damage in direct proportion to the amount of negligence of each of the parties.” (Id. at p. 829.) A plaintiff’s proportionate negligence merely reduces the amount of the judgment against a defendant. (Ibid.) (2c) In the case at hand, the jury found by special verdict that both CCB and Wisper were negligent and caused damage to Wisper and that their proportionate negligence was, respectively, 25 percent and 75 percent. The jury also found that the total damages suffered by Wisper and International were $1,445,953.60.15 The court entered judgment against CCB in favor of International in the amount of $11,820.33. Applying CCB’s 25 percent proportionate liability to Wisper’s damages of $1,434,133.27 (i.e., $1,445,953.60 less $11,820.33 for the International award), the court entered judgment against CCB in favor of Wisper in the amount of $358,533.32. CCB asserts these “damages” [960]*960awarded against it were necessarily “uncertain” and that Civil Code section 3287 prejudgment interest could not be awarded. As to Wisper, we agree.16
The case law interpreting Civil Code section 3287 provides some guidance to its application in the instant case. As discussed above, “[t]he policy underlying authorization of an award of prejudgment interest is to compensate the injured party—to make that party whole for the accrual of wealth which could have been produced during the period of loss. [Citations.]” (Cassinos v. Union Oil Co., supra, 14 Cal.App.4th at p. 1790.)
The court in Cassinos also said: “The test for recovery of prejudgment interest under [Civil Code] section 3287, subdivision (a) is whether defendant actually know[s] the amount owed or from reasonably available information could the defendant have computed that amount. [Citation.]” (Cassinos v. Union Oil Co., supra, 14 Cal.App.4th at p. 1789, original italics; Hartford Accident & Indemnity Co. v. Sequoia Ins. Co. (1989) 211 Cal.App.3d 1285, 1307 [260 Cal.Rptr. 190]; Chesapeake Industries, Inc. v. Togova Enterprises, Inc. (1983) 149 Cal.App.3d 901, 907 [197 Cal.Rptr. 348].) “The statute [Civil Code section 3287] does not authorize prejudgment interest where the amount of damage, as opposed to the determination of liability, ‘depends upon a judicial determination based upon conflicting evidence and is not ascertainable from truthful data supplied by the claimant to his debtor.’ [Citations.]” (Fireman’s Fund Insurance Co. v. Allstate Ins. Co. (1991) 234 Cal.App.3d 1154, 1173 [286 Cal.Rptr. 146].) Thus, where the amount of damages cannot be resolved except by verdict or judgment, prejudgment interest is not appropriate. (Stein v. Southern Cal. Edison Co., supra, 7 Cal.App.4th at p. 573.)
There is a related rule that “the legal interest allowable under [Civil Code] section 3287 cannot be defeated by setting up an unliquidated counterclaim as an offset. [Citations.]” (Chesapeake Industries, Inc. v. Togova Enterprises, Inc., supra, 149 Cal.App.3d at p. 907.) Wisper would apply this rule to classify the claims as liquidated when each check was deposited, and to allow full prejudgment interest to be paid even allowing the 75 percent setoff for comparative negligence. However, such an approach is erroneous for the reason stated in Chesapeake Industries Inc., supra, at page 914: “The fact it is possible to determine with some certainty one figure which is but a single [961]*961element in the mathematical calculations involved in deriving a claim does not necessarily render the claim itself either certain or calculable.” (Original italics.)
Further, as the court said in Polster, Inc. v. Swing (1985) 164 Cal.App.3d 427, 435 [210 Cal.Rptr. 567]: “[T]he cases indicate that where there is a large discrepancy between the amount of damages demanded in the complaint and the size of the eventual award, that fact militates against a finding of the certainty mandated by [Civil Code section 3287].” Conversely, where there is no significant disparity between the amount claimed in the complaint and the final judgment, this factor generally tends to show that damages were certain or capable of calculation. (Stein v. Southern Cal. Edison Co., supra, 7 Cal.App.4th at p. 573; Credit Managers’ Assn. v. Brubaker (1991) 233 Cal.App.3d 1587, 1595 [285 Cal.Rptr. 417].) The greater the disparity between the complaint and the damages, however, the less likely prejudgment interest is appropriate.
The United States Ninth Circuit Court of Appeals dealt with this issue in a case involving equitable indemnity in National Union Fire Ins. v. Showa Shipping Co. (9th Cir. 1995) 47 F.3d 316. In that case the court held Civil Code section 3287 prejudgment interest was not appropriate in an equitable indemnity action, stating “[defendant] not only disputed whether it was liable, but also, if liable, its liability in proportion to that of the other settling defendants. While the amount [plaintiff] contributed to the settlement of the underlying action was capable of being made certain as of the date of the settlement, [defendant’s] share of that settlement was uncertain. Accordingly, the District Court erred in awarding prejudgment interest to [plaintiff].” (National Union Fire Ins., supra, at p. 324.) The court found that “an award of prejudgment interest . . . was inappropriate as the damages were not capable of being made certain before a trial and a determination of the relative fault of the parties," (Id. at p. 325.)
Applying these principles to the facts before us, it is clear the amount of damages owed by CCB to Wisper was not subject to calculation until after the completion of a trial. Although the universe of Wisper’s damage was calculable—that is, the number of checks totaling in excess of $1.4 million—the question of whether and to what extent CCB had any liability for Wisper’s loss was hotly disputed. At the end of the battle, Wisper emerged with a mere 25 percent of its claimed damages. Thus, there is a significant disparity between that which was sought and that which was ultimately found appropriate. Only one element of the claim was certain until the jury made its findings. (Chesapeake Industries, Inc. v. Togova Enterprises, Inc., supra, 149 Cal.App.3d at p. 914.)
[962]*962More importantly, it is clear the policy underlying the requirement for prejudgment interest where the damages are deemed “certain” or “capable of being made certain . . (Civ. Code, § 3287) is that in situations where the defendant could have timely paid that amount and has thus deprived the plaintiff of the economic benefit of those funds, the defendant should therefore compensate with appropriate interest.
The difficulty in applying such policy in this case is patent from the facts, including Wisper’s hiring of an embezzler literally out of jail to manage its funds. It exercised no meaningful oversight, allowing him to steal from it amounts in excess of $50,000 a month. Wisper permitted the embezzler to be a payee on its checks and did not look at its own monthly reports, which demonstrated these massive thefts by its ex-felon employee. It is not surprising under such circumstances that the question of whether CCB was responsible for any portion of the loss was hotly disputed. These facts do not present a case in which CCB could have paid damages which were certain or capable of being made certain, absent a fully litigated apportionment of fault.
Contrary to Wisper’s assertions, this is not a case in which the concept of comparative fault should make a great difference in the outcome of the proceeding. Undoubtedly, there may be cases in which a plaintiff who recovers virtually all of the claimed damages, except for a minor percentage based on his or her comparative fault, would still be entitled to an award of prejudgment interest.
This is not such a case, however, because of the vast disparity between the claimed damage and that which was awarded, arising from a factual environment in which it could reasonably be inferred and was decided that most, if not all, of Wisper’s loss was a result of its own irresponsible behavior. At the end of the day, Wisper, because of its own carelessness, was found by the trier of fact to have three times the responsibility for the loss than could properly be attributed to CCB for any contribution its negligence made to the loss. The amount of damage could not be determined until after trial. (Fireman’s Fund Ins. Co. v. Allstate Ins. Co., supra, 234 Cal.App.3d at p. 1173; Stein v. Southern Cal. Edison Co., supra, 1 Cal.App.4th at p. 573.) Hence, the trial court properly found the damages requested were neither certain nor capable of being made certain within the provisions of Civil Code section 3287. The jury was never requested to award any prejudgment interest under Civil Code section 3288. Therefore we find the trial court correctly denied the request for prejudgment interest.

The Court Did Not Abuse Its Discretion by Imposing Sanctions on Higgs for Discovery Abuses*
Disposition
We reverse (1) the denial of Banamex’s costs as a prevailing party, and (2) the award of postjudgment interest to Wisper and International from the date of the verdict rather than the date of entry of the judgment. In all other respects the judgment is affirmed. The order imposing sanctions against Higgs is affirmed. We remand this matter for further proceedings consistent with this opinion. The parties shall bear their own costs on appeal.
Benke, Acting P. J., concurred.
