OPINION ON REHEARING EN BANC
ROGELIO VALDEZ, Chief Justice.Appellee, Kajima International, Inc. (“Kajima”), moved for rehearing en banc of this Court’s opinion issued November 10, 2004, in which the Court concluded that Formosa Plastics Corp., USA (“Formosa”) met its burden to disqualify AW. “Chip” Hutchison, Kajima’s expert witness, on the basis that Hutchison’s colleague, Steven Huyghe, previously consulted with Formo*444sa. Formosa Plastics Corp., USA v. Kajima Int’l, Inc., No. 13-02-00385-CV, 2004 WL 2534207, 2004 Tex.App. LEXIS 9950, *15 (Tex.App.-Corpus Christi Nov. 10, 2004, no pet. h.). The Court reversed the judgment and remanded the matter for a new trial with directions that Hutchison and others from his firm would not be permitted to testify. See id. at *20. Justice Castillo’s dissenting opinion concluded that Formosa had waived the side-switching issue, and would have affirmed the judgment of the trial court. Id. at *83 (Castillo, J., dissenting).
The Court has granted rehearing en banc. We withdraw our original opinion and judgment issued on November 10, 2004, and issue this opinion and accompanying judgment in their stead. On rehearing, we conclude that Formosa failed to meet its burden of proof to disqualify Hutchison, and we affirm the judgment of the trial court.
I. Background
Kajima International Inc. (“Kajima”), an industrial construction company, submitted several bids for work on Formosa’s expansion plant project located in Point Comfort, Texas. Formosa awarded Kajima five contracts, some involving piping work in the olefins area and others involving piping and equipment setting work in the polypropylene plant. Each contract specified a schedule of performance. The general terms and conditions common to all contracts permitted Kajima to work overtime only if Kajima or its subcontractors delayed the work, and, in such an event, Kajima received no additional compensation for the overtime.
Performance took much longer than provided for in the contracts, causing Ka-jima’s costs to vastly exceed the contract amount paid by Formosa. Kajima asserts it was required to spend this money as a result of Formosa’s fraudulent conduct in connection with the bidding process and its fraudulent inducement of extra-contractual work. According to Kajima, the engineering drawings for its work at the polypropylene plant were full of errors and inaccuracies, yet Formosa knowingly misrepresented the quality of the design drawings for the project during the bidding process. Kajima asserts Formosa fraudulently induced it to enter into the contracts and make artificially low bids on the contracts by withholding information relating to the design and drawings of the polypropylene plant. Kajima further asserts Formosa knowingly provided Kajima with a false schedule concerning the ole-fins plant which failed to reveal that multiple contractors would be working in the same location, and at the same time, as that planned by Kajima, thus preventing Kajima from executing its responsibilities under the contracts. Moreover, according to Kajima, Formosa engaged in a “string along” fraud scheme in which Formosa made repeated false promises to compensate Kajima for delays, disruptions, bid omissions, and additional costs in order to keep Kajima working. At the conclusion of the project, Kajima had spent in excess of $38 million but had received only $10 million from Formosa.
Formosa counters that Kajima spent in excess of the contract prices because of Kajima’s own bidding and contract administration mistakes. Formosa asserts the drawings were adequate for building and bidding and, when problems arose, Kajima was paid pursuant to the contract. Formosa further contends that Kajima knew other contractors would be working within its area and that any conflict in scheduling was the result of Kajima’s own mismanagement.
Kajima sued Formosa and Formosa Plastics Corp., Texas (“Formosa Texas”) in *445January 1993 for breach of contract, fraud, and quantum meruit arising from five of the construction contracts. The matter was first tried to a jury in 1997. The jury found that Formosa did not breach any of the five contracts but did fraudulently induce one of the contracts. The trial court subsequently rendered judgment for Kaji-ma for $4,491,066.65. Kajima appealed, and this Court reversed and remanded the case for a new trial. Kajima Int’l Inc. v. Formosa Plastics Corp., USA, 15 S.W.3d 289, 294 (Tex.App.-Corpus Christi 2000, pet. denied).
The case was tried again in 2002. Kaji-ma nonsuited Formosa Texas and the matter was submitted to the jury on the issue of fraud. The jury found Formosa guilty of fraud and awarded Kajima approximately $15 million dollars, or roughly 60% of the damages it sought. The trial court rendered judgment for Kajima for actual damages of $15,432,123.45, prejudgment interest of $14,210,269.65, and $403,156.86 in costs. This appeal ensued. Formosa raises nine issues on appeal.
II. Expert Disqualification
We will first address Formosa’s third issue on appeal, that is, the expert disqualification issue which the Court found determinative of the appeal in its original opinion. Formosa alleges that Kajima’s expert, A.W. “Chip” Hutchison, should not have been permitted to testify. Formosa first argues that an expert retained and paid by one party cannot switch sides and testify as an expert for the opposing party in the same case. Formosa contends that the firm of A.W. Hutchison & Associates, Inc. served as Formosa’s “consulting” experts and Formosa satisfied all requirements to disqualify the firm and Chip Hutchison. In contrast, Kajima contends that any information Formosa provided to Hutchison’s colleague, Steven Huyghe, was discoverable and not confidential, and no confidential information was shared with Hutchison or Huyghe. Kajima further asserts that, even if confidential information was disclosed to Huyghe, that knowledge could not be imputed to Hutchison. The factual background regarding this matter is critical to understanding and properly analyzing this issue.
When the question of litigation with Ka-jima first originated, Formosa retained the law firm of Jones, Day, Reavis & Pogue (“Jones Day”). Counsel for Jones Day contacted Huyghe, an expert in heavy industrial construction and president of A.W. Hutchison & Associates of California, Inc. Huyghe and an assistant met with attorneys from Jones Day and in-house counsel for Formosa. They spoke about “strategies for this case and what kind of defense we ought to establish,” and “what the contentions were that Kajima had against Formosa and how we were going to answer some of those allegations.” They further discussed Kajima’s allegations against Formosa and which allegations might be true or were not true. Huyghe was to assist in document review and organization in order to “see what we had.” The Formosa attorneys never requested that Huyghe maintain confidentiality regarding these conversations or documents, nor did they request that he execute any confidentiality agreement.
Huyghe reviewed and organized documents that had been produced by Formosa to Kajima and documents produced from Kajima to Formosa. He prepared a work plan outlining his proposed method for evaluating the situation as well as an index of relevant documents received from Kaji-ma.
Huyghe sent several letters to Jones Day and copied some of those letters to Hutchison, his colleague at A.W. Hutchi-son & Associates, Inc., in Atlanta, a sepa*446rate but related corporation from that which employed Huyghe.1
The first of these letters, dated June 14, 1993, discussed the consulting group’s “possible involvement” in the litigation, provided examples of prior work, and mentioned that Hutchison was available for a meeting “if you so desire.” A letter dated October 19, 1993, discussed what A.W. Hutchison & Associates had done for clients in the past and explained the methodology usually employed to evaluate problems. This letter was marked as “privileged and confidential.” Huyghe also provided a letter agreement for the engagement of the group and included a proposed confidentiality agreement, which Formosa’s attorneys never signed.
In late 1993, Formosa transferred its defense from Jones Day to the law firm of Porter & Hedges. The Porter & Hedges attorneys received Huyghe’s proposed work plan and the index of documents from Kajima, but decided not to employ Huyghe’s services. On April 6,1994, Porter & Hedges told Huyghe to consider hijn-self “indefinitely on hold.” By this point, Huyghe had submitted bills totaling approximately $22,000 for more than 167 hours of work. On April 15, 1994, Huyghe contacted Porter & Hedges and, detailing his group’s work on prior cases, requested an opportunity to meet with Formosa’s attorneys to present his thoughts on the case. Porter & Hedges failed to accept this invitation.
A few months later, Kajima’s attorney approached Huyghe about consulting with Kajima in the lawsuit. Huyghe informed the attorneys at Jones Day, who suggested contacting Porter & Hedges about this possibility and any potential conflicts of interest. Apparently Huyghe did not contact the new attorneys. Huyghe did sign a “conflict certification” affidavit provided by Kajima, in which he certified that “A.W. Hutchison & Associates, Inc., has not received any confidential information from any Formosa entity or from its counsel.” Kajima did not hire Huyghe; however, it did hire both Chip Hutchison and Brian Rogers of A.W. Hutchison & Associates, Inc. in Atlanta, Georgia.
At the trial, Huyghe testified that he had not received any confidential information from Formosa. In contrast, an attorney for Jones Day testified that she had revealed confidential information, including settlement strategies, to Huyghe. Nevertheless, Jones Day admitted that it had not made a determination regarding whether Huyghe would be utilized as a testifying expert.
Huyghe testified that he had never discussed any Formosa-related information with Hutchison or Rogers. Counsel for Jones Day testified that the lawyers at the firm had no communications with Hutchinson or Rogers, did not disclose any information to Hutchinson or Rogers, and knew of no confidential information that was ever disclosed from Formosa to Hutchinson or Rogers. Counsel also knew of no contact with Jones Day and Hutchinson in Atlanta. Hutchison himself testified that he had no knowledge of any Formosa-related information known to Huyghe.
On the basis of this lack of disclosure, the trial court denied Formosa’s motion to disqualify Hutchison and Rogers from testifying, and the jury subsequently awarded a verdict in favor of Kajima.
The chief issues before this Court are: (1) what guidelines should have framed the *447trial court’s decision whether to disqualify Hutchison and A.W. Hutchison and Associates (“AWH”); and (2) whether the trial court’s decision was properly executed within those guidelines. Any question about an expert’s breach of his or her duties, fiduciary or otherwise, to a former client is not at issue here. Likewise, the hypothetical question of whether Huyghe should have been disqualified is not before the Court, nor is the hypothetical question of whether disqualification and other sanctions would have been appropriate if Hutchison and Huyghe were lawyers and not engineering experts.
We write separately on this issue on rehearing en banc for the following reasons. The Court’s dissenting opinion on rehearing adopts the two-part expert disqualification test outlined in Koch Ref. Co. v. Jennifer L. Boudreaux MV, 85 F.3d 1178, 1181 (5th Cir.1996). While we do not disagree with the dissent’s utilization of this test, and, in fact, would apply the same basic test with additional factors utilized by other courts, we diverge from the dissent insofar as it concludes that Formosa met its burden for disqualification under this standard. That is, the dissent states that it was objectively reasonable for Formosa to believe that it had a confidential relationship with Hutchison and confidential information was disclosed to Hutchison. We conclude otherwise. The concurring opinion on rehearing asserts that Formosa waived its right to seek disqualification of Hutchison and AWH because Formosa failed to assert a claim of confidentiality over information imparted to Huyghe, and would affirm the judgment below. Rather than finding waiver, as does the concurrence, we conclude simply that Formosa has failed to meet its initial burden to show that disqualification is necessary.
Thus, we turn to the issue currently before the Court, that is, the disqualification of a non-attorney expert witness based on another expert’s work for the opposing party. We will also examine the expert’s contacts with the opposing party in the litigation. While the issue of expert disqualification in terms of an expert’s relationship with a law firm has been tangentially discussed in opinions by the Texas Supreme Court and other appellate courts, the issue at hand is one of first impression. See, e.g., In re Am. Home Prods. Corp., 985 S.W.2d 68, 73 (Tex.1998) (orig.proeeeding) (considering disqualification of counsel for plaintiffs because of their retention of testifying expert who had previously worked as consulting expert for defendant in the same litigation); In re Bell Helicopter, 87 S.W.3d 139, 151 (Tex.App.-Fort Worth 2002, orig. proceeding) (considering disqualification of law firm because of its retention of consulting expert who had previously worked for defendant in the same litigation). More specifically, the issues of first impression we must address are: (1) whether an expert should be disqualified where he was retained by one side but was somehow related to an expert previously retained by the opposing party; and (2) whether the entire firm of experts to which both of these experts belong should be disqualified.
We first must decide the appropriate standard of review. In general, we review the trial court’s decision to admit or exclude expert evidence for an abuse of discretion. State Farm Fire & Cas. Co. v. Rodriguez, 88 S.W.3d 313, 318 (Tex.App.-San Antonio 2002, pet. denied); see Guadalupe-Blanco River Auth. v. Kraft, 77 S.W.3d 805, 810 (Tex.2002). We see no reason not to apply this standard herein even though this matter turns not on qualifications or reliability, but rather on an alleged conflict of interest. We reverse *448based on the erroneous admission or exclusion of evidence only if the appellant shows eiTor that was calculated to cause and probably did cause the rendition of an improper judgment. Tex.R.App. P. 44.1(a); City of Brownsville v. Alvarado, 897 S.W.2d 750, 753 (Tex.1995); Doncaster v. Hernaiz, 161 S.W.3d 594, 601 (Tex.App.-San Antonio 2005, no pet.) (“error on questions of evidence is generally not reversible unless the appellant can show that the whole case turns on the particular evidence admitted or excluded”). We note that disqualification is a drastic measure that courts should impose only “hesitantly, reluctantly, and rarely.” Owen v. Wangerin, 985 F.2d 312, 317 (7th Cir.1993); Koch Ref. Co., 85 F.3d at 1181; Hewlett-Packard Co. v. EMC Corp., 330 F.Supp.2d 1087, 1092 (N.D.Cal.2004); United States v. Salamanca, 244 F.Supp.2d 1023, 1025 (D.S.D.2003); Proctor & Gamble Co. v. Haugen, 184 F.R.D. 410, 413 (D.Utah 1999); Palmer v. Ozbek, 144 F.R.D. 66, 67 (D.Md.1992).
When disqualification based on a prior relationship with an adversary is requested, the majority of courts have adopted a two-prong test which balances the competing interests of the parties. See W. Va. ex rel. Billups v. Clawges, 620 S.E.2d 162, 167, 218 W.Va. 22 (2005) (collecting cases); Mitchell v. Wilmore, 981 P.2d 172, 175 (Colo.1999). Under the test, disqualification is warranted if: (1) the moving party possessed an objectively reasonable basis to believe that a confidential relationship existed between that party and the expert witness; and (2) confidential or privileged information was in fact provided to the expert by the moving party. See Koch Ref. Co., 85 F.3d at 1181; Hewlett-Packard Co., 330 F.Supp.2d at 1093.2 In the usual case, both factors must be present to merit disqualification. See Hewlett-Packard, 330 F.Supp.2d at 1093 (explaining that if only one of the factors is present, disqualification is likely inappropriate). Other courts also apply additional factors, sometimes generally spoken of in such general terms as “fundamental fairness” and “prejudice.” These courts consider and weigh competing policy considerations, whether disqualification would be fair to the affected party or would be unduly prejudicial, whether disqualification would promote the integrity of the judicial process, and whether the public has an interest in allowing or not allowing the expert to testify. See Grioli v. Delta Int’l Mach. Corp., 395 F.Supp.2d 11, 13 (E.D.N.Y.2005) (citing cases); Hewlett-Packard Co., 330 F.Supp.2d at 1094-95 (citing cases). As stated in Hewlett-Packard:
It is important to consider other policy concerns in order to achieve the goal of protecting the integrity of the adversary process and of promoting public confidence in the legal system. Such concerns include consideration of the parties’ strategic positions ... and avoidance of creating ‘troublesome incentives for both experts and the retaining party.’ For example, if experts are permitted to breach confidentiality agreements, they might be motivated ‘to sell their opinions to the opposing parties or the highest bidder without concern about the potential confidentiality of their previous consultations. The retaining party might be motivated ‘not to withdraw a previously designated expert while litigation is pending for fear that the party’s confidential information would become available to its adversary.’ However, if ‘experts are too eas*449ily disqualified, unscrupulous attorneys may attempt to create relationships with numerous potential experts at a nominal fee hoping to preempt the ability of their adversaries to obtain expert assistance.’
Hewlett-Packard, Co., 330 F.Supp.2d at 1095 (internal citations omitted).
Under this test, the moving party bears the burden of demonstrating that disqualification is necessary. Grioli, 395 F.Supp.2d at 14; Hewlett-Packard Co., 330 F.Supp.2d at 1096. The party seeking disqualification bears the burden of establishing both the existence of confidentiality and its nonwaiver. United States ex rel. Cherry Hill Convalescent Ctr., Inc. v. Healthcare Rehab Sys., Inc., 994 F.Supp. 244, 249 (D.N.J.1997); Cordy v. Sherwin-Williams Co., 156 F.R.D. 575, 580 (D.N.J.1994).
In evaluating the first prong of the test, that is, whether there was an objectively reasonable basis to believe that a confidential relationship existed with the expert, courts have considered various factors, including:
(1) whether the relationship was one of long standing and involved frequent contacts instead of a single interaction with the expert;
(2) whether the parties entered into a formal confidentiality agreement;
(3) whether the expert was asked to agree not to discuss the case with the opposing parties or counsel;
(4) whether the expert derived any of his specific ideas from work done under the direction of the retaining party;
(5) the number of meetings between the expert and the attorneys;
(6) whether the party retained the expert to assist in litigation;
(7) whether the expert was paid a fee;
(8) whether work product was discussed or documents were provided to the expert;
(9) whether alleged confidential communications were from expert to party or vice versa;
(10) whether the moving party funded or directed the formation of the opinion to be offered at trial; and
(11) the extent to which the expert learned of the party’s litigation strategies.
Lacroix v. Bic Corp., 339 F.Supp.2d 196, 200 (D.Mass.2004); Hewlett-Packard, 330 F.Supp.2d at 1093; Stencel v. Fairchild Corp., 174 F.Supp.2d 1080, 1083 (D.Ca.2001); Mayer v. Dell, 139 F.R.D. 1, 3 (D.D.C.1991); Paul v. Rawlings Sporting Goods Co., 123 F.R.D. 271, 280 (S.D.Ohio 1988). A long-term relationship is more likely to exist when the “record supports a longstanding series of interactions, which have ... coalesced to create a basic understanding of the retaining party’s modus operandi, patterns of operation, and decision-making process.” Hewlett-Packard, 330 F.Supp.2d at 1093 (quoting Marvin Lumber & Cedar Co. v. Norton Co., 113 F.R.D. 588, 591 (D.Minn.1986)). Conversely, informal consultations occur when the expert received no insight into the present litigation strategy. Id. In examining this prong of the test, the emphasis is not on whether the expert was retained per se, but whether there was a relationship that would permit the litigant to reasonably expect that any communications would remain confidential. Id.; Lacroix, 339 F.Supp.2d at 200 (D.Mass.2004).
Confidential information is information “of either particular significance or [that] which can be readily identified as either attorney work product or within the scope of attorney-client privilege.” Hewlett-Packard, 330 F.Supp.2d at 1093 (cita*450tions omitted). It could include discussion of the party’s strategy in the litigation, the kinds of experts the party expects to retain, the party’s view of the strengths and weaknesses of each side, the role of each of the experts to be hired, and anticipated defenses. Id. at 1094; Lacroix, 339 F.Supp.2d at 201. Communication based upon technical information, as opposed to legal advice, is not considered privileged, Nikkal Indus., Ltd. v. Salton, Inc., 689 F.Supp. 187, 191-92 (S.D.N.Y.1988), nor is information that is routinely discoverable. In re Mitchell, 981 P.2d at 176; Palmer v. Ozbek, 144 F.R.D. 66, 68 (D.Md.1992). Unlike attorney-client communications, discussions between parties or counsel and experts do not carry the presumption that confidential information was exchanged. Hewlett-Packard, 330 F.Supp.2d at 1094; Nikkal Indus., Ltd., 689 F.Supp. at 191—92. Because the burden is on the party seeking disqualification, that party should point to specific and unambiguous disclosures that, if revealed, would prejudice the party. Hewlett-Packard, 330 F.Supp.2d at 1094.
In urging this Court to disqualify Hutchison and AWH, Formosa cites authority regarding the disqualification of legal personnel and law firms and suggests that Hutchison and AWH should be disqualified in this case under the same rules that prevent an attorney from representing an adversary against a former client. While the rationale for disqualifying an expert is similar to that for disqualifying an attorney who has a conflict of interest, the two situations are distinguishable and subject to different standards. See Grioli, 395 F.Supp.2d at 13; In re Ambassador Group, Inc., Litigation, 879 F.Supp. 237, 241 (E.D.N.Y.1994). Unlike attorneys, expert witnesses generally serve as sources of information and not necessarily as recipients of confidences. See, e.g., English Feedlot v. Norden, 833 F.Supp. 1498, 1501 (D.Colo.1993) (“The expert disqualification standard must be distinguished from the attorney-client relationship because experts perform very different functions in litigation than attorneys.”); Paul, 123 F.R.D. at 281 (stating that attorneys occupy “a position of higher trust, with concomitant fiduciary duties, to a client than does an expert consultant”). The majority of courts that have considered the issue of expert disqualification have applied different standards from those used when reviewing the disqualification of an attorney. This approach is well-reasoned and we adopt it. Accordingly, the Court will not apply the stringent attorney-client conflict standards in determining whether Kaji-ma’s expert in this case should be disqualified.
Applying the foregoing principles to the instant case, it seems clear that Huyghe would be disqualified from representing Kajima, if indeed that were the issue currently before us. It was objectively reasonable for Formosa to conclude that a confidential relationship existed between Huyghe and Formosa, and the evidence before the trial court would have supported the conclusion that confidential or privileged information was disclosed to Huyghe.3 This would be a clear-cut case *451of side-switching that would immediately merit disqualification. See Koch, 85 F.3d at 1181.
However, the issue currently before the Court is not the disqualification of Huyghe, but whether the trial court abused its discretion in refusing to disqualify Hutchison. We hold that Formosa failed to meet its burden to meet either prong of the Koch test: (1) that it was objectively reasonable for Formosa to conclude that it had a confidential relationship with Hutchison; or (2) confidential or privileged information was in fact provided to Hutchison by either Formosa, as the moving party, or Huyghe, his colleague at AWH.
Based on our review of the record evidence, it was not objectively reasonable for Formosa to conclude that it had a confidential relationship with Hutchison. Formosa did not have a prior relationship with Hutchison and never met, corresponded, or spoke with him about this litigation. Although Huyghe told Formosa that Hutchison was available to work on the Kajima case, Hutchison did not perform any work for Formosa on this matter, in coordination with Huyghe or otherwise. Accordingly, disqualification is not warranted. See Hewlett-Packard, 330 F.Supp.2d at 1093.
Insofar as Formosa’s motion to disqualify sought the disqualification of the entire consulting group of AWH, we have previously determined that the disqualification rules applicable to attorneys, which would allow for disqualification of a firm based on imputed knowledge, should be inapplicable to expert witnesses. See Stencel, 174 F.Supp.2d at 1083; United States ex rel Cherry Hill Convalescent Ctr., Inc., 994 F.Supp. at 249. Accordingly, we do not find that Formosa had a confidential relationship with AWH, or that Formosa had a confidential relationship with Hutchison merely by virtue of Hutchison’s association with Huyghe or Huyghe’s consulting group.
Moreover, even if we were to conclude that it was objectively reasonable for Formosa to believe that it had a confidential relationship with Hutchison, there remains no showing regarding the second prong of the Koch test, that is, that any confidential or privileged information was disclosed to Hutchison by either Jones Day or Huyghe. Saliently, none of the trial witnesses testified that they disclosed confidential information to Hutchison. We have closely examined the written communications that Huyghe sent to Formosa and copied to Hutchison, and we see no signs therein of privileged or confidential information. These communications consisted primarily of marketing efforts, budget estimates, and proposals for work. In fact, at the stage of the litigation when those letters were sent, Huyghe’s work on the case was clearly in its infancy and additional work remained to be done.
We conclude that Formosa failed to meet its burden under the two-prong test for disqualification articulated by the Fifth Circuit in Koch. See Koch Ref. Co., 85 F.3d at 1178. However, in considering the issue of disqualification, we also consider additional factors, including the competing policy considerations, applicable to the requested disqualification. Based on the record before the Court, the trial court’s decision not to disqualify Hutchison and AWH was neither prejudicial nor fundamentally unfair to either of the parties. *452The policies of allowing experts to pursue their trade, allowing parties to select their own experts, and preventing gamesmanship, whereby parties create conflicts solely for the purposes of preventing their adversary from using the services of the expert, outweigh the policy of preventing conflicts under the particular factual circumstances present in the instant case. Formosa has not clearly identified any prejudice it has suffered from Kajima’s retention of Hutchison or AWH. In contrast, Kajima clearly would suffer hardship if Hutchison were now disqualified at this stage of the litigation. In considering concepts of fundamental fairness and prejudice, prejudice is particularly likely at a late stage in the litigation, at which time disqualification is more likely to disrupt the judicial proceedings. Hewlett-Packard, 330 F.Supp.2d at 1095. In the instant case, the matter has now twice been to trial, and accordingly, Kajima would be prejudiced by Hutchison’s disqualification.
Formosa bore the burden of proof with respect to the disqualification of Hutchison and AWH, and we conclude that it failed to sustain that burden. Koch Ref. Co., 85 F.3d at 1181; Hewlett-Packard, 330 F.Supp.2d at 1095-96. Because of this conclusion, we need not address the issue of waiver as discussed by the concurrence. Accordingly, we overrule Formosa’s third issue insofar as it relates to disqualification.
In a subissue, Formosa contends that the trial court abused its discretion by failing to exclude Hutchison’s testimony regarding damages because the testimony was not reliable. According to Formosa, Hutchison’s damage testimony was based on his own “Hutchison Method,”4 also known as the “as-released method,” which has no support in law or within the construction industry. Kajima contends, in response, that Hutchison’s opinions were both relevant and reliable.
An expert witness may testify regarding scientific, technical, or other specialized subjects if the expert is qualified and if the expert’s opinion is relevant and based on a reliable foundation. Tex.R. Evid. 702; Helena Chem. Co. v. Wilkins, 47 S.W.3d 486, 499 (Tex.2001); E.I. du Pont de Nemours & Co. v. Robinson, 923 S.W.2d 549, 556 (Tex.1995). In determining whether expert testimony is rehable, a court should examine “the principles, research, and methodology underly*453ing an expert’s conclusions.” Mack Trucks v. Tamez, 206 S.W.3d 572, 578 (Tex.2006) (quoting Exxon Pipeline Co. v. Zwahr, 88 S.W.3d 623, 629 (Tex.2002)). When the testimony involves scientific knowledge, the expert’s conclusions must be based on the methods and procedures of science, or the testimony is “no more than ‘subjective belief or unsupported speculation.’” Robinson, 923 S.W.2d at 557 (quoting Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579, 590, 113 S.Ct. 2786, 125 L.Ed.2d 469 (1993)). We apply certain non-exclusive factors to examine the reliability of expert testimony based on scientific knowledge, but these factors may not apply when testimony involves technical or other specialized knowledge. Mack Trucks, 206 S.W.3d at 578; see Gammill v. Jack Williams Chevrolet, 972 S.W.2d 713, 726 (Tex.1998) (listing factors). The Supreme Court in Kumho Tire Co. v. Carmichael suggested that the Daubert standard is a flexible one, and that the trial court should “make certain that an expert, whether basing testimony upon professional studies or personal experience, employs in the courtroom the same level of intellectual rigor that characterizes the practice of an expert in the relevant field.” Kumho Tire Co. v. Carmichael, 526 U.S. 137, 152, 119 S.Ct. 1167, 143 L.Ed.2d 238 (1999). When the expert testimony is based on technical or other specialized knowledge, there must be some basis for the opinion to show its reliability. Gammill, 972 S.W.2d at 726. And, there cannot be too great an “analytical gap” between the data and the expert opinion offered. Id.
Formosa does not challenge Hutchison’s qualifications or the relevance of his opinions, but instead focuses solely on the reliability of Hutchison’s expert testimony insofar as it allegedly was based on the “as-released” method to quantify damages. Based on our review of the instant trial record, we conclude that Hutchison’s testimony did not include the criticized “as-released method” for calculating damages. The “as-released” method relates to delay causation, and Hutchison’s opinion testimony was not based on the causation of delays, but rather, was limited to valuation of the work performed by Kaji-ma. Hutchison’s testimony regarding the calculation of the reasonable value of the work performed by Kajima was objectively verifiable and was based on unit pricing and quantities and utilized standard estimating techniques. Formosa does not offer any criticism relevant to this testimony. Accordingly, we conclude that Formosa’s attack on the reliability of Hutchison’s testimony was misplaced, and Formosa’s subissue on this subject is overruled. We overrule Formosa’s third issue.
III. Fraud Damages .
In its first issue, Formosa argues that the evidence is legally and factually insufficient to support the jury’s award of fraud damages. According to Formosa, a rational basis must exist for a damages finding.
The trial court’s charge asked the jury to determine Kajima’s fraud damages and instructed the jury to consider “[t]he difference, if any, between the reasonable value (excluding any profit) of Kajima’s work it performed for Formosa and what Kajima was paid.” The jury awarded Ka-jima $15,432,123.45.
Juries have broad discretion in assessing damages where the law provides no precise legal measure; a jury’s findings will not be disregarded merely because its reasoning in arriving at its figures may be unclear, so long as a rational basis for its calculation exists. McMillin v. State Farm Lloyds, 180 S.W.3d 183, 201 (Tex.App.-Austin 2005, no pet.); Swank v. *454Sverdlin, 121 S.W.3d 785, 799 (Tex.App.-Houston [1st Dist.] 2003, pet. denied); First State Bank v. Keilman, 851 S.W.2d 914, 930 (Tex.App.-Austin 1993, writ denied).
Formosa argues that the record is devoid of any evidence supporting the jury’s award of $15,432,123.45 and that the numerical sequencing of the finding shows that the award was randomly chosen and not based on the evidence before the jury. Formosa argues that this case is identical to that considered by the Austin Court of Appeals in First State Bank v. Keilman, 851 S.W.2d 914 (Tex.App.-Austin 1993, writ denied). In Keilman, the plaintiffs brought a usury claim against First State Bank, arguing that they were charged $7,161.44 in unauthorized interest. See id. at 931. The bank submitted evidence that it did not charge unauthorized interest. Id. The jury heard evidence that damages were either $7,161.44 or zero, yet awarded $360. Id. at 929. The Austin Court held that no evidence supported this award, as it was “inexplicable in light of the evidence” and “it appeared that the jury pulled a number out of a hat.” Id. at 931.
In the instant case, Kajima asked the jury to award it $25,307,287. In contrast, Formosa argued that the jury should award Kajima nothing. However, this is not a situation, as in Keilman, where there were only two possible answers to the damage question. The evidence before the jury did not present a situation where damages could be calculated based on only two possible choices. That is to say, “[r]ather than a binary choice or a series of binary choices, this evidence presented the jury with a range of possible awards.” McMillin, 180 S.W.3d at 203. The fact that the jury chose neither the figure requested by Kajima nor the figure suggested by Formosa does not invalidate the award.
Formosa supports its argument as to the randomness of the award by pointing to a question from the jury. During deliberations, the jury sent a note to the trial court asking: “Judge, in question number two, are we to base our answer on the amount that is owed, 25.3 million, or how much they deserve.” In response, the trial court referred the jury back to the jury charge. Formosa contends that the jury inappropriately chose to award an amount that it believed Kajima deserved rather than follow the instructions given to it. Again, we disagree. The question from the jury regarding how much Kajima deserved equates to the reasonable value, excluding profit, of its work.
We conclude that the evidence here was sufficient to enable reasonable jurors to choose from a range of possible damage awards that included the $15,432,123.45 amount ultimately awarded. Kajima’s expert, Hutchison, testified regarding the damages suffered by Kajima. Hutchison first calculated the total costs incurred by Kajima to be $38,717,854. He then subtracted $3,330,574 from that figure, as costs that did not provide value to Formosa, thus arriving at $35,387,380, as representing the reasonable value of the work performed by Kajima. Hutchison then subtracted $10,000,000 as the amount paid by Formosa. Kajima argued that the resulting figure, $25,387,380, represented the difference in value between what was given by Kajima and what was paid by Formosa.
In contrast, Formosa argued that Kaji-ma’s figure should be reduced because of wasted labor that did not add value for Formosa. Mike Holloway, a Formosa field supervisor, specifically testified that half of all labor spent by Kajima was wasted. Other testimony attacked Kajima’s productivity and work methodology.
*455In the case before us, the testimony of the witnesses and experts was lengthy and detailed. The evidence regarding damages contained many components to be considered and disparate estimates of values to be assigned to each. See Aboud v. Schlichtemeier, 6 S.W.3d 742, 749 (Tex.App.-Corpus Christi 1999, pet. denied). The damages awarded by the jury were well within the range of evidence. This evidence supplied a basis for the jury to rationally ascertain the value of work performed by Kajima and what Kajima was paid. We hold that there is legally and factually sufficient evidence to support the jury’s finding in regard to actual damages. We overrule Formosa’s first issue.
IV. Charge Error
In its second issue, Formosa contends that the trial court’s submission of a single broad-form liability question is reversible error. In this case, the jury was asked, “Did Formosa commit fraud against Kaji-ma?” Formosa argues that the charge should have provided separate answer blanks for each of the five contracts at issue in this case. Formosa contends that the failure to include separate answer blanks for each contract makes it impossible to trace the jury’s damage award back to any specific contract or contracts and prevents Formosa from challenging the sufficiency of the evidence as to any of the individual contracts.
We are required to order a new trial under Crown Life Insurance Co. v. Casteel when “a single broad-form liability question incorporates multiple theories of liability” in such a way that we “cannot determine whether the jury based its verdict on an improperly submitted invalid theory.” See Crown Life Ins. Co. v. Casteel, 22 S.W.3d 378, 388 (Tex.2000).
We disagree with Formosa’s argument. Casteel applies to multiple theories of liability; by contrast, the instant situation involves only one-fraud. Contrary to Formosa’s contention, Casteel does not require a granulated submission as to multiple acts under a single theory of liability.5 See id. Moreover, I would note that the error of including a factually unsupported claim in a broad-form jury question is not always reversible. Romero v. KPH Consol., Inc., 166 S.W.3d 212, 227 (Tex.2005). To be reversible, the erroneous instruction must have “probably prevented the appellant from properly presenting the case to the court of appeals.” See Tex.R.App. P. 44.1(a)(2); Romero, 166 S.W.3d at 227. Here, the underlying conduct upon which the jury found liability was essentially the same for all five of the contracts at issue. On this record, we are “reasonably certain that the jury was not significantly influenced by issues erroneously submitted to it.” See Romero, 166 S.W.3d at 227-28. Consequently, even if Casteel applied in the instant analysis, we would have found that any error in the jury instruction was harmless. We overrule Formosa’s second issue.
V. Ratification
In its fourth issue, Formosa argues that the trial court erred by refusing to submit its requested issue on ratification to the jury. According to Formosa, it pleaded and properly requested a jury *456submission on ratification and there was ample evidence to support an issue on ratification. Ratification is a plea in avoidance and thus an affirmative defense which, absent trial by consent, is waived unless affirmatively pleaded. Land Title Co. v. F.M. Stigler, Inc., 609 S.W.2d 754, 756 (Tex.1980).
A person ratifies an unauthorized act if, by word or conduct, with knowledge of all material facts, he confirms or recognizes the act as valid. Miller v. Kennedy & Minshew, 142 S.W.3d 325, 342-43 (Tex.App.-Fort Worth 2003, pet. denied); Mo. Pac. R.R. Co. v. Lely Dev. Corp., 86 S.W.3d 787, 792 (Tex.App.-Austin 2002, pet. dism’d). Ratification need not be shown by express word or deed but may be inferred by a course of conduct. Miller, 142 S.W.3d at 342-43; Mo. Pac. R.R. Co., 86 S.W.3d at 792.
In Fortune Production Co. v. Conoco, Inc., 52 S.W.3d 671 (Tex.2000), the Texas Supreme Court held that a party who does not have a continuing obligation to perform under a contract, but nevertheless continues to perform after learning of a fraud, ratifies the fraud and therefore cannot recover damages for the period of time when the party knew of the fraud. Id. at 680; see Meyer v. Cathey, 167 S.W.3d 327, 331 (Tex.2005). A party may ratify an agreement induced by fraud in such a way that both the right to rescind and a claim for damages are foreclosed, although ratification can also be in such a way that loss of the right to rescind the contract occurs without loss of the right to sue for damages. See Fortune Prod. Co., 52 S.W.3d at 677-78; Harris v. Archer, 134 S.W.3d 411, 428 (Tex.App.-Amarillo 2004, pet. denied).
It is well established that litigants have a right to a fair trial before a jury that is properly instructed on the issues authorized and supported by the law governing the case. Harris County v. Smith, 96 S.W.3d 230, 234 (Tex.2002). “If an issue is properly pleaded and is supported by some evidence, a litigant is entitled to have controlling questions submitted to the jury.” Triplex Comm. v. Riley, 900 S.W.2d 716, 718 (Tex.1995); see Tex.R. Civ. P. 278; see also Elbaor v. Smith, 845 S.W.2d 240, 243 (Tex.1992).
The trial court has broad discretion in submitting jury questions and instructions. Plainsman Trading Co. v. Crews, 898 S.W.2d 786, 791 (Tex.1995). “Failure to submit a question shall not be deemed a ground for reversal of the judgment unless a substantially correct question has been requested in writing and tendered by the party complaining of the judgment.” Tex.R. Crv. P. 278. “When a trial court refuses to submit a proper question or instruction, reversal is not required unless- the error probably caused the rendition of an improper judgment. See Tex.R.App. P. 44.1; Union Pac. R.R. Co. v. Williams, 85 S.W.3d 162, 170 (Tex.2002).
Formosa argues that evidence supporting the submission of ratification includes a meeting in March of 1992, at which Kajima’s management realized it would lose $25 million unless it walked off the job. Formosa unilaterally characterizes this evidence as proof that, “[b]y recognizing its right to cancel the contracts, Kaji-ma acknowledged the alleged fraud. Nevertheless, Kajima chose to go forward under the contracts, even though it knew that it would cost $25 million to complete the contracts. This is ratification.” Yet Formosa offers neither any proof nor any argument which would explain how the evidence of Kajima’s March 1992 meeting would possibly qualify as ratification in light of Kajima’s evidence of Formosa’s contemporaneous and even subsequent *457promises of compensation for delays, disruptions, and bid omissions offered to induce Kajima to remain on the job. In the same vein, Formosa also argues that Kaji-ma knew of alleged misrepresentations regarding the CTCI drawings, yet continued to perform under the CM903 contract. Formosa also argues that Kajima knew of fraud regarding the LM905 and LM910 contracts, that is, that Kajima knew that other contractors were behind schedule and were congesting Kajima’s work area, both before signing the contracts and before beginning construction.
We reject Formosa’s view of the evidence and the law of ratification. Formosa has not presented evidence that Kajima acted with “full knowledge of the fraud and of all material facts.” Fortune Prod. Co., 52 S.W.3d at 677. Nor has Formosa adduced evidence that Kajima showed “the intention, clearly manifested, of abiding by the affirmance of the contract” or evidence of acts that indicated Kajima’s intention to waive the fraud. See id. Accordingly, we overrule Formosa’s fourth issue.
VI. Exclusion of Evidence
In its fifth issue, Formosa contends that the trial court committed reversible error when it prevented Formosa from submitting evidence that Kajima’s damages were not caused by fraud. Formosa argues that the trial court excluded evidence that Kaji-ma omitted “millions of dollars worth of items from its bids” and also excluded other testimony showing that Kajima’s damages were self-inflicted and were not proximately caused by any alleged fraud on Formosa’s part.
Whether to admit or exclude evidence is a matter committed to the trial court’s sound discretion. See City of Brownsville, 897 S.W.2d at 753; Bic Pen Corp. v. Carter, 171 S.W.3d 657, 676 (Tex.App.-Corpus Christi 2005, pet. granted). To reverse a judgment based on a claimed error in admitting or excluding evidence, a party must show that the error probably resulted in an improper judgment. Tex. R.App. P. 44.1(a); Alvarado, 897 S.W.2d at 753. In determining if the excluded evidence probably resulted in the rendition of an improper judgment, we review the entire record. Interstate Northborough P’ship v. State, 66 S.W.3d 213, 220 (Tex.2001). A successful challenge to evidentia-ry rulings usually requires the complaining party to show that the judgment turns on the particular evidence excluded or admitted. Id. We will not reverse a judgment because a trial court erroneously excluded evidence when the evidence in question is cumulative and not controlling on a material issue dispositive to the case. Id.
We conclude that the excluded evidence was both irrelevant and cumulative of other evidence adduced at trial. Evidence regarding items omitted from Kajima’s bid is irrelevant in a fraud case involving an out-of-pocket measure for damages. See Formosa Plastics Corp., USA v. Presidio Eng’rs. & Contractors, 960 S.W.2d 41, 49 (Tex.1998). Moreover, the excluded evidence was cumulative insofar as several witnesses testified regarding Kajima’s bids and the omissions from the bids. Other excluded evidence, such as the alleged mismanagement, bribery, and theft by one of Kajima’s managers, was also irrelevant to the ultimate issue regarding whether or not Formosa committed fraud.
Formosa’s entire defense of the case centered on Kajima’s alleged mismanagement of the project causing self-inflicted loss. In the context of Formosa’s entire defense, we cannot agree that exclusion of the evidence caused an improper verdict. Accordingly, we overrule Formosa’s fifth issue.
*458VII. Out of Pocket Losses
In its sixth issue, Formosa alleges that Kajima’s out-of-pocket loss could not have exceeded half of what the jury awarded, and the trial court erroneously refused to admit evidence of Kajima’s self-inflicted losses and to instruct the jury on mitigation.
There are two measures of damages for fraud. They are the benefit-of-the-bargain measure and the out-of-pocket measure. See id. Benefit-of-the-bargain damages are the difference between the value as represented and the value received. Id. Out-of-pocket damages compensate a defrauded party for the difference between the value of that with which he or she has parted and the value actually received. Id.
The damages question at issue asked the jury to determine Kajima’s out-of-pocket measure of damages — one of the two recognized damage models for fraud. See id. Formosa contends that under this measure the relevant figures, the value paid and the value received, were established at the time the contracts were signed. See Arthur Andersen v. Perry Equip. Corp., 945 S.W.2d 812, 817 (Tex.1997). Formosa contends that Hutchison testified that the value of Kajima’s work “under normal conditions,” that is, the value of what Kajima contracted to provide when the relevant contracts were signed, was approximately $17 million dollars. The value that Formosa agreed to pay Kajima was $10 million dollars. Formosa thus argues that the evidence establishes that, at most, Kaji-ma’s out-of pocket loss was the difference between these two values, a figure somewhere between $7 million and $8 million.
We disagree with the basis for Formosa’s contention. As an initial matter, the Arthur Andersen construct, which measures damages at the time the contract is signed, applies to a purchase and sale of a business. See id. As such, it is inapplicable to a construction contract. Even if it did apply, however, we would not apply it to a contract for services wherein the evidence showed “string-along” fraud arising after execution of the contracts, as the evidence in this case establishes. A damage analysis focusing solely on the date that the contract was executed would omit damages attributable to post-contract fraud. See Kajima, 15 S.W.3d at 293-94.
There is evidence to support the jury’s award of approximately $15 million based on the difference between the value of that with which Kajima parted and the value Kajima actually received. See Formosa Plastics Corp. USA., 960 S.W.2d at 49. Hutchison testified that the “as planned” cost of the job under normal conditions was roughly $17 million, but that the abnormal conditions concealed by Formosa resulted in an additional $18 million being spent to complete the project. Accordingly, Kajima parted with approximately $35 million and actually received only $10 million. The jury’s award of approximately $15 million was well under the $25 million difference between the value of that with which Kajima parted and the value Kajima received.
Formosa contends that the trial court erroneously refused to admit evidence of Kajima’s “self-inflicted” losses. We have already addressed this argument in connection with Formosa’s fifth issue and need not address it further herein.
Finally, Formosa alleges that the trial court erroneously refused to instruct the jury on mitigation. The concept of mitigation requires the plaintiff to exercise reasonable care in minimizing its damages. Great Am. Ins. Co. v. North Austin MUD, 908 S.W.2d 415, 426 (Tex.1995). The duty to mitigate arises in both con*459tract and tort cases. See Pulaski Bank & Trust Co. v. Tex. Am. Bank, 759 S.W.2d 723, 735 (Tex.App.-Dallas 1988, writ denied). The duty to mitigate damages arises only if it can be done with “trifling expense or with reasonable exertions.” Gunn Infiniti v. O’Byrne, 996 S.W.2d 854, 857 (Tex.1999) (quoting Walker v. Salt Flat Water Co., 128 Tex. 140, 96 S.W.2d 231, 232 (Tex.1936)).
We reject Formosa’s contention that the trial court erred in refusing to instruct the jury on mitigation. First, there is authority for the proposition that an injured party is not required to minimize damages resulting from the fraud. Meadolake Foods, Inc. v. Estes, 218 S.W.2d 862, 868 (Tex.Civ.App.-El Paso 1948), writ ref'd n.r.e., 148 Tex. 13, 219 S.W.2d 441 (1949); see Duperier v. Tex. State Bank, 28 S.W.3d 740, 754 (Tex.App.-Corpus Christi 2000, pet. dism’d by agmt); New Process Steel Corp., Inc. v. Steel Corp. of Tex., Inc., 703 S.W.2d 209, 215 (Tex.App.-Houston [1st Dist.] 1985, writ ref'd n.r.e.).
Second, Formosa had the burden to show that Kajima did not use ordinary care in reducing or avoiding its damages. See Moulton v. Alamo Ambulance Serv., 414 S.W.2d 444, 450 (Tex.1967). To be entitled to a mitigation instruction, the evidence must (1) clearly show that the plaintiffs decision not to mitigate caused further damages, and (2) sufficiently guide the jury in determining which damages were attributable to the plaintiffs decision not to mitigate. Hygeia Dairy Co. v. Gonzalez, 994 S.W.2d 220, 225 (Tex.App.-San Antonio 1999, no pet.). The defendant does not have to prove an exact amount of damages attributable to the plaintiffs conduct, but is required to present some evidence from which the jury can make a reasoned calculation of the losses that occurred due to the plaintiffs decision not to mitigate. Id.
In the instant case, Formosa has failed to meet its burden to show that Kajima’s damages could be mitigated with “trifling expense or with reasonable exertions,” that Kajima’s decisions caused further damages, or to produce any evidence from which the jury could determine which damages were attributable to Kajima. Because Formosa’s proof did not meet these requirements, the court correctly refused the instruction on mitigation. We overrule Formosa’s sixth issue.
VIII. Single Business Enterprise
Prior to trial, the trial court granted Kajima’s motion for partial summary judgment and found that Formosa USA and Formosa Texas were operating as a single business enterprise. Accordingly, the jury was instructed that it could consider the conduct of Formosa Texas when deciding the liability of Formosa USA.
In its seventh issue, Formosa contends that the trial court erred by granting a summary judgment finding that Formosa USA and Formosa Texas operated as a single business enterprise. Formosa contends that (1) actual fraud is required for a finding of single business enterprise, (2) single business enterprise is a fact question for the jury, and (3) even if the issue could be considered as a matter of law, Formosa submitted sufficient evidence to create a fact issue.
For the purposes of legal proceedings, subsidiary corporations and parent corporations are separate and distinct “persons” as a matter of law, and the separate entity of corporations will generally be observed by the courts even where one company may dominate or control the other company, or treats the other company as a mere department, instrumentality, or agency. Valero S. Tex. Processing Co. v. Starr County Appraisal Dist., 954 *460S.W.2d 863, 866 (Tex.App.-San Antonio 1997, pet. denied). The “single business enterprise” theory is an equitable doctrine used to disregard the separate existence of corporations when the corporations are not operated as separate entities, but rather integrate their resources to achieve a common business purpose. Old Republic Ins. Co. v. Ex-Im Servs. Corp., 920 S.W.2d 393, 395-96 (Tex.App.-Houston [1st Dist.] 1996, no writ).
Several intermediate appellate courts, including this Court, have recognized a concept of “single business enterprise” in one context or another. See, e.g., Nat’l Plan Adm'rs, Inc. v. Nat’l Health Ins. Co., 150 S.W.3d 718, 744 (Tex.App.-Austin 2004, pet. filed) (recognizing doctrine as a valid equitable means of piercing the corporate veil to impose liability); Bridgestone Corp. v. Lopez, 131 S.W.3d 670, 686-87 (Tex.App.-Corpus Christi 2004, pet. granted, judgm’t vacated w.r.m.) (finding exercise of jurisdiction comported with due process where two corporations operated as a single business enterprise); El Puerto de Liverpool, S.A. de C.V. v. Servi Mundo Llantero, S.A. de C.V., 82 S.W.3d 622, 636-37 (Tex.App.-Corpus Christi 2002, pet. dism’d w.o.j.) (affirming denial of special appearance where companies shared common employees, used a centralized accounting system, and performed services for each other); In re U-Haul Int’l, 87 S.W.3d 653, 657 (Tex.App.-San Antonio 2002, no pet.) (considering the issue of document production from entities alleged to operate as a single business enterprise); N. Am. Van Lines, Inc. v. Emmons, 50 S.W.3d 103, 119-21 (Tex.App.-Beaumont 2001, pet. denied) (recognizing equitable doctrine may apply under exceptional circumstances); Aluminum Chems. (Bolivia), Inc. v. Bechtel Corp., 28 S.W.3d 64, 68 (Tex.App.-Texarkana 2000, no pet.) (concluding that appellant had waived issue pertaining to single business enterprise); Hall v. Timmons, 987 S.W.2d 248, 255-56 (Tex.App.-Beaumont 1999, no pet.) (concluding that more than a scintilla of evidence supported the jury’s finding of a single business enterprise); Paramount Petroleum Corp. v. Taylor Rental Ctr., 712 S.W.2d 534, 536 (Tex.App.-Houston [14th Dist.] 1986, writ ref'd n.r.e.) (same); see SSP Partners v. Gladstrong Invs. (USA) Corp., 169 S.W.3d 27, 44 (Tex.App.-Corpus Christi 2005, pet. filed) (declining to extend the doctrine to a party’s vicarious liability for the wrongful acts of a non-party); see also Allright Tex., Inc. v. Simons, 501 S.W.2d 145, 150 (Tex.Civ.App.-Houston [1st Dist.] 1973, writ ref'd n.r.e.); Murphy Bros. Chevrolet v. E. Oakland Auto Auction, 437 S.W.2d 272, 275-76 (Tex.Civ. App.-El Paso 1969, writ ref'd n.r.e.). We would note that the supreme court has not spoken on the viability of the single business enterprise theory. See Southern Union Co. v. City of Edinburg, 129 S.W.3d 74, 87 (Tex.2003) (“We need not decide today whether a theory of ‘single business enterprise’ is a necessary addition to Texas law regarding the theory of alter ego for disregarding corporate structure and the theories of joint venture, joint enterprise, or partnership for imposing joint and several liability.”).
Factors to be considered in determining whether separate corporations should be treated as one enterprise include: (1) common employees; (2) common offices; (3) centralized accounting; (4) payment of wages by one corporation to another corporation’s employees; (5) common business name; (6) services rendered by the employees of one corporation on behalf of another corporation; (7) undocumented transfers of funds between corporations; and (8) unclear allocation of profits and losses between corporations. Paramount Petroleum Corp., 712 S.W.2d at 536.
*461The purpose of the single business enterprise theory, like the alter ego theory and other doctrines designed to pierce the corporate veil, is to prevent an inequitable result. See Castleberry v. Branscum, 721 S.W.2d 270, 271 (Tex.1986).6 The courts have articulated several different rationales for disregarding the corporate fiction, including: (1) when it is used as a means of perpetrating fraud; (2) where a corporation is organized and operated as a mere tool or business conduit of another corporation; (3) where it is used to evade an existing legal obligation; (4) where it is employed to achieve or perpetrate a monopoly; (5) where it is used to circumvent a statute; and (6) where the corporate fiction is relied upon as a protection of crime or to justify wrong. Id. at 272.
We first address Formosa’s assertion that actual fraud is required for a finding of single business enterprise. Formosa bases its argument on article 2.21(A)(2) of the Texas Business Corporation Act. See Tex. Bus. CoRP. Act Ann. art. 2.21(A)(2) (Vernon 2003).7 This section provides:
A. A holder of shares, an owner of any beneficial interest in shares, or a subscriber for shares whose subscription has been accepted, or any affiliate thereof or of the corporation, shall be under no obligation to the corporation or to its obligees with respect to:
[[Image here]]
(2) any contractual obligation of the corporation or any matter relating to or arising from the obligation on the basis that the holder, owner, subscriber, or affiliate is or was the alter ego of the corporation, or on the basis of actual fraud or constructive fraud, a sham to perpetrate a fraud, or other similar theory, unless the obligee demonstrates that the holder, owner, subscriber, or affiliate caused the corporation to be used for the purpose of perpetrating and did perpetrate an actual fraud on the obligee primarily for the direct personal benefit of the holder, owner, subscriber, or affiliate ...
Tex. Bus. Corp. Ann. art. 2.21(A) (Vernon 2003). The 1996 Bar Committee Comment to article 2.21 of the Texas Business Corporation Act states:
Castleberry, in particular its use of constructive fraud as a basis of piercing the corporate veil, was considered by many practitioners to be incorrectly decided. Further, while questionable in the context of tort claims, the use of constructive fraud as a means of piercing the corporate veil created a cloud on the sanctity of contract and the public policy of recognizing corporations as separate entities apart from them shareholders. In response to Castleberry, Article 2.21 of the TBCA was amended in 1989 to establish a clear legislative standard under which the liability of a shareholder for the obligations of a corporation is to be determined in the context of contractual obligations and all matters relating thereto.
*462Id. art. 2.21 cmt. (Vernon 2003); see Willis v. Donnelly, 199 S.W.3d 262, 272 (Tex.2006). Under the current statute, a shareholder “may not be held liable to the corporation or its obligees with respect to ... any contractual obligation of the corporation ... on the basis that the holder ... is or was the alter ego of the corporation or on the basis of actual or constructive fraud, a sham to perpetrate a fraud, or other similar theory ... unless the shareholder caused the corporation to be used for the purpose of perpetrating and did perpetrate an actual fraud on the obligee primarily for the direct personal benefit of the shareholder-” Id. art. 2.21(A); see Willis, 199 S.W.3d at 272.8 The statute is the “exclusive” means for imposing liability on a corporation for the obligations of another corporation in which it holds shares. S. Union Co., 129 S.W.3d at 87; see Willis, 199 S.W.3d at 272 (providing that the liability of a shareholder for a contractual corporate debt under this statute “is exclusive and preempts any other liability imposed for that obligation under common law or otherwise”) (citing current § 21.224). The references to “alter ego” and “other similar theory” in the current statute were added in 1993 amendments to the Business Corporation Act. Willis, 199 S.W.3d at 272; see Act of May 7, 1993, 73d Leg., R.S., ch. 215, § 2.05(A)(2), 1993 Tex. Gen. Laws 418, 446. There are statutory exceptions to this general rule, as for example, where the shareholder expressly agrees to be personally liable to the obli-gee for the obligation. Tex. Bus. CoRP. Act. Ann. art. 2.21(B)(1) (Vernon 2003); see now Tex. Bus. ORgs.Code Ann. § 21.225(1).
Article 2.21 applies to contractual obligations “or any matter relating to or arising from the obligation.” Although this matter was submitted to the jury on the issue of fraud, the fraud at issue arises from the contracts between the parties. Accordingly, we assume, without deciding, that this is a matter relating to or arising from the contracts. Thus, we further assume that article 2.21 applies to the instant case.
Utilizing the language of article 2.21, if this case involved a contract signed by Formosa Texas, then Formosa USA would be under no obligation to Formosa Texas or Kajima with respect to any contractual obligation of Formosa Texas, or any matter relating to or arising from that obligation, on the basis that Formosa USA is a single business enterprise with Formosa Texas, unless Kajima demonstrated that Formosa USA caused Formosa Texas to *463be used for the purpose of perpetrating and did perpetrate an actual fraud on Kaji-ma, primarily for the direct personal benefit of Formosa USA.
However, that is not the case now before the Court.
Based on the facts before this Court, we conclude that article 2.21 does not apply in the instant case because the contracts were signed by Formosa USA, not Formosa Texas, its wholly owned subsidiary. There is no Formosa Texas contract. Formosa Texas is not a party to the contracts at issue in this case.
Moreover, in the instant case, the jury found Formosa USA guilty of its own fraud. As discussed herein, evidence supports the jury’s finding that Formosa USA committed fraud. Because the evidence of Formosa USA’s own fraud is sufficient to support the jury’s finding that Formosa USA committed fraud, Formosa has not been harmed by the trial court’s ruling on the single business enterprise.
In its next two subissues, Formosa contends that whether a single business enterprise exists is a fact question for the jury, and even if the issue could be considered as a matter of law, Formosa submitted sufficient evidence to create a fact issue. As an initial matter, we note that appellate courts have considered single business enterprise to be a matter of law. See Allright Tex., Inc. v. Simons, 501 S.W.2d 145, 150 (Tex.Civ.App.-Houston [1st Dist.] 1973, writ ref'd n.r.e.); see also Murphy Bros. Chevrolet Co. v. E. Oakland Auto Auction, 437 S.W.2d 272, 276 (Tex.Civ.App.-El Paso 1969, writ ref'd n.r.e.). However, whether or not single business enterprise is a fact issue for the jury or an issue that can be established as a matter of law, we conclude that Kajima offered sufficient evidence for the trial court to grant a partial summary judgment resolving that Formosa USA and Formosa Texas should be treated as one enterprise.
The companies had common employees during the relevant period of time, such as Susan Wang, executive vice president for both companies. The companies shared common offices at 9 Peach Tree Hill Road, Livingston, New Jersey 07039. With regard to the project at issue, the companies had a centralized or coordinated accounting system to the extent they related to approval of construction change orders with regard to the project. Both companies shared a common business name: “Formosa.” Employees of one corporation rendered services on behalf of the other. Glenn Dobbs, an employee of Formosa Texas, performed bid analyses for Formosa USA on the construction project. Robert Hsueh and Simon Chang, both employees of Formosa Texas, reported to L.F. Pan, who was employed by Formosa USA. The director of legal services for Formosa Texas, Camp Mehrens, reported to Jack Wu, an officer of both Formosa Texas and Formosa USA. Another employee, Jack Huang, testified he was not sure if he worked for Formosa USA or Formosa Texas on the Point Comfort project. Another employee, Jeff Tseng, testified he did not understand the differences between Formosa USA and Formosa Texas.
Considering these facts and comparing them to the factors enunciated in Paramount Petroleum Corp. v. Taylor Rental Ctr., for determining whether separate corporations should be treated as one enterprise, we conclude that Kajima met its burden of showing both no genuine issue of material fact and entitlement to partial judgment as a matter of law on the issue of single business enterprise. See Tex.R. Civ. P. 166a(c); Paramount Petroleum Corp., 712 S.W.2d at 536. We overrule Formosa’s seventh issue.
*464IX. Withholding Evidence
In its eighth issue, Formosa alleges that the trial court erred by withholding documentary evidence from the jury during its deliberations even though the documents had been admitted into evidence. Formosa’s complaint concerns twenty-seven volumes of CTCI drawings, engineering design drawings used to bid and build the CM 903 project. Formosa contends that these drawings were the center of Kajima’s fraud claim insofar as Kajima asserted that the drawings were defective, Formosa knew they were defective, and Formosa withheld that information from Kajima. In contrast, Formosa contended that the expert testimony indicated the CTCI drawings were suitable to bid and build the project. Accordingly, Formosa contends that the documents were crucial for the jury to review. Kajima argues that the drawings, other than those included in the CM 903 bid package, were not in evidence. The trial court allowed the jury to have only the drawings that were part of the CM 903 bid package.
Texas Rule of Civil Procedure 281 provides that:
The jury may, and on request shall, take with them in their retirement the charges and instructions, general or special, which were given and read to them, and any written evidence, except the depositions of witnesses, but shall not take with them any special charges which have been refused. Where part only of a paper has been read in evidence, the jury shall not take the same with them, unless the part so read to them is detached from that which was excluded.
This rule is mandatory, and the trial court is required to send all exhibits admitted into evidence to the jury room during deliberations. First Employees Ins. Co. v. Skinner, 646 S.W.2d 170, 172 (Tex.1983). However, any error in failing to send exhibits to the jury room during deliberations does not call for reversal unless the error probably caused the rendition of an improper judgment. See Tex.R.App. P. 44.1(a)(1).
In this case, the reporter’s record does not indicate that all of the drawings were admitted into evidence. In fact, earlier in the trial, the trial court did not allow some of the drawings to be published to the jury on grounds that they were not part of the contract. Accordingly, the trial court did not err. Even if the trial court erred; however, we cannot conclude that any alleged error probably caused the rendition of an improper judgment. We overrule Formosa’s eighth issue.
X. Prejudgment Interest
In its ninth and final issue, Formosa contends that the trial court erred by awarding Kajima excessive prejudgment interest. Specifically, Formosa contends that, under Johnson & Higgins of Tex., Inc. v. Kenneco Energy, Inc., 962 S.W.2d 507 (Tex.1998), the trial court should have applied section 304.105 of the Texas Finance Code to reduce Kajima’s claim for prejudgment interest. See Tex. Fin.Code Ann. § 304.105 (Vernon 2006). Section 304.105(b) provides, in part, that:
If judgment for a claimant is more than the amount of a settlement offer of the defendant, prejudgment interest does not accrue on the amount of the settlement offer during the period the offer may be accepted.
Id. § 304.105(b). Formosa contends that it made several settlement offers to Kaji-ma, including an offer of $15,361,000, and the trial court should not have awarded prejudgment interest for the relevant periods of time during which the offers could have been accepted.
*465There are two legal sources for an award of prejudgment interest: (1) common law equitable principles; and (2) an enabling statute. Johnson & Higgins of Tex., Inc., 962 S.W.2d at 528 (Tex.1998). In Johnson & Higgins, the Texas Supreme Court recognized that the statutory prejudgment interest scheme conflicted in several respects with the common law regarding prejudgment interest. Id. at 528-31. Accordingly, the court harmonized certain aspects of the common law prejudgment interest accrual scheme to accord with that found in the finance code. Id.; City of Houston v. Texan Land & Cattle Co., 138 S.W.3d 382, 388 (Tex.App.-Houston [14th Dist.] 2004, no pet.). Specifically, the Texas Supreme Court (1) changed the common law accrual date for prejudgment interest to match that ordered by statute, (2) ordered that prejudgment interest be computed as simple interest, as in the statute, rather than as compound interest, and (3) made the prejudgment interest rate the same as the postjudgment interest rate, again, as in the statute. Johnson & Higgins of Tex., Inc., 962 S.W.2d at 531-32.
Formosa contends that Johnson & Higgins mandates the application of section 304.105(b) to this case. The express language of the finance code indicates otherwise. Chapter 304 of the finance code governs judgment interest. See generally Tex. Fin.Code Ann. §§ 304.001-.302 (Vernon 2006). Section 304.101 of the code provides that subchapter B, which governs prejudgment interest, “applies only to a wrongful death, personal injury, or property damage case of a court of this state.” Id. § 304.101. Section 304.105, addressing the effect of a settlement offer on the accrual of prejudgment interest, is part of subchapter B, and accordingly, applies only to wrongful death, personal injury, or property damage cases. Id. § 304.105. The instant case is not a case for wrongful death, personal injury, or property damage; accordingly, section 304.105 does not apply. See id.
Contrary to Formosa’s argument, nothing in Johnson & Higgins can be read to require the application of section 304.105(b) to this case. In fact, in Johnson & Higgins, the supreme court itself rejected the wholesale application of the finance code to all common law cases. “We hold that section 6 means what it says: statutory prejudgment interest applies only to wrongful death, personal injury, and property damage cases.” See Johnson & Higgins of Tex., Inc., 962 S.W.2d at 530. Moreover, this argument has previously been rejected by the Texar-kana Court of Appeals. Head Indus. Coatings & Servs., Inc. v. Maryland Ins. Co., 981 S.W.2d 305, 311 (Tex.App.-Texarkana 1998, pet. denied); see de la Garza v. de la Garza, 185 S.W.3d 924, 928 (Tex.App.-Dallas 2006, no pet.) (stating that prejudgment interest under the finance code applies only to wrongful death, personal injury, and property damage cases).9 Accordingly, we overrule Formosa’s ninth and final issue.
XI. Conclusion
We conclude that Formosa failed to meet its burden of proof to disqualify *466Hutchison, and, accordingly, we overrule Formosa’s third issue. We also overrule the remainder of Formosa’s issues on appeal. We affirm the judgment of the trial court.
Concurring opinion by Justice CASTILLO. Dissenting opinion by Justice YÁÑEZ, joined by Justice HINOJOSA.. Prior to the trial of this matter, Hutchison's corporation, A.W. Hutchison & Associates, Inc., merged with A.W. Hutchison & Associates of California, Inc., which employed Huyghe.
. This two-part test was first set forth in Paul v. Rawlings Sporting Goods Co., 123 F.R.D. 271, 278 (S.D.Ohio 1988), and later framed by Wang Laboratories, Inc. v. Toshiba Corp., 762 F.Supp. 1246, 1248 (E.D.Va.1991).
. According to testimony from counsel with Jones Day, the firm had not yet made a decision regarding whether it would designate Huyghe as a testifying expert or utilize him as a consulting expert when meeting with Huyghe. The law is abundantly clear that the subject matter on which an expert witness is expected to testify, the mental impressions and opinions held by the expert and the facts known to the expert (regardless of when the factual information was acquired) which relate to or form the basis of the mental impressions and opinions held by the expert, are discoverable. See Tex.R. Civ. P. 166b(2)(e); see also Tex.R. Civ. P. 166b(3)(b); In re Am. Home Prods. Corp., 985 S.W.2d 68, 73 (Tex.*4511998). Discoverable information is not, by definition, "confidential information” as contemplated by the Koch test.
. The party seeking to exclude the expert’s testimony must offer more than mere argument; it must offer some proof of the alternative methodologies or proof of the weakness of the methodology used;
GM’s lawyers lampoon the methods Syson used to test the sun visor and to reach conclusions about the engineering compromises that would optimize a sun visor’s performance in light of the risks involved. But their cri de coeur is not backed up by references to any body of scientific knowledge. What tests do engineers use to resolve questions of the kind Syson addressed? What tests should he have performed? What data did he overlook? Counsel apparently want appellate judges to make a priori judgments about how scientific inquiry should be conducted. That way quackeiy lies. A profession resolves questions of method in the same way it reaches, conclusions about other empirical issues; which method is best is a question itself subject to scientific inquiry.... A litigant that wants a court of appeals to set aside a district judge’s decision to admit expert testimony has to do more than appeal to a lawyer’s sense of how science should be done.
DePaepe v. GMC, 141 F.3d 715, 720 (7th Cir.1998); see also Zenith Elecs. Corp. v. WH-TV Broad. Corp., 395 F.3d 416, 419 (7th Cir.2005) (noting that Daubert analysis "will not do to stop with lawyers’ arguments pro and con, for these may fail to appreciate the difficulties that bona fide experts encounter. Scientific decisions must be made by scientific rather than rhetorical means.”).
. If Formosa’s misinterpretation of Casteel were correct, even a simple car wreck case would require a granulated submission of whether the defendant driver was negligent in failing to keep a proper lookout, negligent in failing to maintain a safe speed, negligent in failing to remain in the proper lane of traffic, negligent in steering, negligent in failing to apply the brakes, etcetera. See Crown Life Ins. Co. v. Casteel, 22 S.W.3d 378, 388 (Tex.2000).
. Castleberry is cited herein for its historical discussion of the origins of these theories, but it has been largely superceded by subsequent statutory amendments. Compare Castleberry v. Branscum, 721 S.W.2d 270 (Tex.1986); with Tex. Bus. Orgs.Code § 21.223 (Vernon Supp.2006) (effective January 1, 2006).
. The elements necessary to impose personal liability on a shareholder have been carried forward in section 21.223 of the Business Organizations Code. See Tex Bus. Org.Code Ann. § 21.223 (Vernon Supp.2006). That code became effective January 1, 2006, however, the Business Corporation Act continues in effect until January 1, 2010 for corporations formed before January 1, 2006.
. We note that case law is divided regarding whether actual fraud is required for vicarious liability under the statute. Some cases, including cases decided by this Court, have held that no proof of fraud is required to recover under a single business enterprise theory because the single business enterprise theory relies on equity, similar to partnership principles of liability. See, e.g., PHC-Minden, L.P. v. Kimberly-Clark Corp., 202 S.W.3d 193 (Tex.App.-Tyler 2005, pet. granted); Bridgestone Corp. v. Lopez, 131 S.W.3d 670, 682 (Tex.App.-Corpus Christi 2004, pet. granted, judgment vacated w.r.m.); N. Am. Van Lines, Inc. v. Emmons, 50 S.W.3d 103, 119 (Tex.App.-Beaumont 2001, pet. denied) (citing Aluminum Chems. (Bolivia), Inc. v. Bechtel Corp., 28 S.W.3d 64, 68 (Tex.App.-Texarkana 2000, no pet.)). Other courts have refused to apply the statute to tort cases and have limited its application to contract cases. See, e.g., Love v. State, 972 S.W.2d 114, 118 (Tex.App.-Austin 1998, pet. denied) (“The Act itself makes clear that actual fraud is required only in the context of contractual obligations.’’). Other cases require actual fraud in any context. See, e.g., Menetti v. Chavers, 974 S.W.2d 168, 174 (Tex.App.-San Antonio 1998, no pet.) ("A finding that no actual fraud was committed destroys not only the attempt to pierce the corporate veil by a showing of an alter ego, but by 'other similar theories.’ ”). Because our disposition of Formosa's argument does not rely on any of these approaches, we need not and will not attempt to reconcile these cases herein.
. Although not cited by Formosa in its brief, we note that dicta in Shoreline, Inc. v. Hisel, 115 S.W.3d 21 (Tex.App.-Corpus Christi 2003, pet. denied), discusses the application of certain sections of chapter 304 of the finance code to an employment discrimination case. See id. at 24-25. Shoreline is distinguishable from the instant case insofar as it concerns the finality of a judgment that failed to specify the amount of prejudgment interest due on a judgment. See id. To the extent that the dicta therein could be construed to indicate that sections of the finance code are applicable to causes of action other than wrongful death, personal injury, or property damage, we would hereby disapprove it.
