OPINION
Opinion By
RPK Capital XVI, L.L.C. and RPK Capital Management, L.L.C. (collectively RPK) sued Wells Fargo Bank Northwest, N.A., in its corporate capacity as owner trustee of an aircraft (Wells Fargo), for conversion and for a declaratory judgment that RPK owns and is entitled to possession of an aircraft thrust reverser. Following a bench trial based partially on stipulated facts, the trial court awarded RPK possession of the thrust reverser, $848,480 in damages, and $624,743.90 in attorneys’ fees for trial and contingent attorneys’ fees on appeal. In seven issues, Wells Fargo argues (1) RPK’s conversion claim is barred by the statute of limitations, (2) RPK was not entitled to possession of the thrust reverser because the thrust reverser is an accession to an aircraft that Wells Fargo acquired in the ordinary course of business, (3) the trial court erred by awarding RPK damages for a defect in the thrust reverser that was discovered, but not caused, by Wells Fargo, (4) RPK’s damages model was based solely on the unreliable testimony of an expert witness, (5) even if the expert testimony was reliable, the evidence was insufficient to support the amount of past and future lost profits awarded by the trial court, and (6) the trial court erred by awarding RPK attorneys’ fees. We affirm in part, reverse and render in part, and reverse and remand in part.
Stipulated Facts
The case was presented to the trial court partially on stipulated facts and partially on evidence offered at trial. As relevant to the issues on appeal, the parties’ stipulations established that, on December 29, 1998, Provident Commercial Group, Inc. (Provident) entered into a lease agreement with American Trans Air, Inc. for an aircraft engine, a thrust reverser, and related equipment. 1 The lease identified the thrust reverser by two generic part numbers, LJ76612 for the left-hand thrust reverser and LJ76610 for the right-hand *697 thrust reverser, rather than by serial numbers. 2 Although the engine lease was recorded with the Federal Aviation Administration in January 1999, there is no public registry for thrust reversers.
In 2008, Provident changed its name to Information Leasing Corporation (IFC), and American Trans Air, Inc. changed its named to ATA Airlines, Inc. (ATA). On December 29, 2003, IFC assigned the lease to Provident Bank. In 2004, ATA filed for bankruptcy. One of ATA’s assets in the bankruptcy was an aircraft it leased from FINOVA Capital Corporation (FINOVA). In the 2004 bankruptcy, ATA rejected the lease with FINOVA. ATA surrendered the aircraft to FINOVA in December 2004. In the 2004 bankruptcy, ATA assumed the lease with Provident for the aircraft engine and the thrust reverser. The lease was subsequently assigned by Provident Bank to LINC Capital, Inc. (LINC). In 2005, LINC assigned the lease to RPK Capital V, L.L.C. and, in 2008, RPK Capital V assigned the lease to RPK Capital XVI, L.L.C.
At some point, FINOVA and related entities filed for bankruptcy. On August 10, 2001, the bankruptcy court confirmed FINOVA’s plan of reorganization. FINO-VA’s 2001 Securities and Exchange Commission Form 10K indicated that as part of its business, FINOVA treated as assets and regularly sold aircraft to third parties at the end of lease terms and that FINO-VA had historically “earned total proceeds from the sale of assets upon lease termination in excess of carrying amounts.” The 2001 FormlOK also stated, “[T]he main objective of the Debtors’ post-confirmation business plan is to maximize the value of their portfolio through the orderly liquidation of the portfolio over time” and that “[T]he Debtors’ largest line of business is Transportation Finance, which primarily consists of various forms of financing of used aircraft.” FINOVA’s Securities and Exchange Commission Form 10-Q for the quarter ending June 30, 2008 stated:
Since emergence from chapter 11 bankruptcy proceedings in August 2001, our business activities have been limited to maximizing the value of our portfolio through the orderly collection of our assets .... We have substantially completed the liquidation of our portfolio and our focus has shifted to the continued wind down of our operations and future dissolution of our entities.
On September 19, 2005, Talos Aviation Limited (Talos) entered into a letter of intent with FINOVA to purchase the aircraft formerly leased by ATA. On October 7, 2005, FINOVA sold the aircraft to Ta-los. Talos then conveyed the aircraft to Wells Fargo as owner-trustee.
In April 2008, ATA again initiated a bankruptcy proceeding. Prior to filing the 2008 bankruptcy, ATA made its annual lease payment to RPK and provided proof of insurance and financial records as required by the lease. In ATA’s 2008 bankruptcy, RPK sought adequate protection of the equipment subject to the lease, including the thrust reverser and related records. On April 25, 2008, RPK made demand on Wells Fargo for “removal and return of a thrust reverser.”
In early May 2008, RPK began an investigation to determine the serial numbers of the thrust reverser that was the subject of *698 the lease. In May 2008, the serial numbers on the thrust reverser attached to the aircraft Wells Fargo purchased from FI-NOVA were 1267003 for equipment on the left side of the aircraft and 1267002 for equipment on the right side of the aircraft. In May 2008, RPK made a more specific demand that Wells Fargo return the thrust reverser bearing those two serial numbers.
On May 27, 2008, NORDAM, a company specializing in the detailed inspection of thrust reversers, conducted an inspection of the thrust reverser at Wells Fargo’s request. The May 2008 inspection was not required by the lease. During the inspection, NORDAM found delamination on sections of the thrust reverser. 3 Because of the delamination, the thrust reverser was tagged as unserviceable. Thrust reversers are interchangeable parts that can be removed from one aircraft and installed on another. In December 2008, the thrust reverser was removed from the aircraft owned by Wells Fargo. Removal of the thrust reverser caused no damage to the aircraft.
The parties introduced additional evidence at trial on several disputed issues. We will discuss the disputed evidence later in this opinion as necessary to address Wells Fargo’s complaints on appeal. Of note, a significant contested issue at trial was whether the thrust reverser on the aircraft owned by Wells Fargo was the thrust reverser that was the subject of the lease between Provident and American Trans Air. Wells Fargo has not challenged on appeal the trial court’s finding the thrust reverser on the aircraft purchased from FINOVA was the thrust reverser that was the subject of the lease and, accordingly, we need not address the evidence introduced at trial relating to this issue.
The trial court found Wells Fargo converted the thrust reverser and awarded RPK possession of the thrust reverser, $848,480 in damages, and $624,743.90 in attorneys’ fees for trial and contingent attorneys’ fees on appeal. The trial court entered findings of fact and conclusions of law based on both the stipulated and contested facts.

Statute of Limitations
In its first issue, Wells Fargo asserts the trial court erred by concluding that RPK’s conversion claim is not barred by the statute of limitations. Wells Fargo asserts (1) RPK’s conversion claim against Wells Fargo accrued in October 2005 when Wells Fargo, through Talos, purchased the aircraft and took possession of the thrust reverser, (2) RPK failed to file suit within two years of the date the claim accrued, and (3) the discovery rule is not applicable to toll the running of the limitations period. Wells Fargo had the burden to prove the affirmative defense of the statute of limitations.
See Tex. Integrated Conveyor Sys., Inc. v. Innovative Conveyor Concepts, Inc.,
Conversion is the “unauthorized and wrongful assumption and exercise of dominion and control over the personal property of another, to the exclusion of or inconsistent with the owner’s rights.”
Waisath v. Lack’s Stores, Inc.,
A person must bring suit for the conversion of personal property “not later than two years after the day the cause of action accrues.” Tex. Civ. Prac. & Rem.Code Ann. § 16.003(a) (West Supp. 2011);

Generally, the limitations period for a conversion claim begins to run at the time of the unlawful taking.
Pipes v. Hemingway,
Relying on
Steinhagen v. Ehl,
Ehl sued Steinhagen and PetroTex for conversion of the original pumps. A jury found Steinhagen and PetroTex converted the property and awarded Ehl $35,431 in actual damages and awarded exemplary damages against both defendants. Id. at 626. The jury also found that Ehl could have discovered the fuel pumps were missing in “Fall to Winter '98” and that Ehl’s conduct waived his conversion claim. Id. The trial court disregarded the jury’s finding on waiver and awarded judgment in favor of Ehl for $115,431. Id.
On appeal, Steinhagen and PetroTex argued the trial court erred by applying the discovery rule to extend the accrual of Ehl’s conversion claim. Without substantive analysis, the court of appeals concluded that, even though Webb’s initial possession of the fuel pumps was lawful under the lease agreement with Ehl, Steinhagen and PetroTex’s removal and sale of Ehl’s pumps “belongs” in the “unlawful possession” class of conversion cases. Id. at 627. The court of appeals further determined that Webb’s possession of the pumps at the time the conversion was committed “would not, in and of itself, trigger the application of the discovery rule.” Id. The court of appeals concluded the legal injury rule, rather than the discovery rule, applied to Ehl’s conversion claim against Ste-inhagen and PetroTex and, therefore, the claim was barred by limitations. Id.
The Corpus Christi Court of Appeals employed a different analysis in
Hofland v. Elgin-Butler Brick Co.,
The court of appeals first concluded there was sufficient evidence to support the trial court’s finding that the conversion occurred when Holland sold Border Brick’s assets to Garza. Id. It then turned to the issue of when Elgin-Butler’s conversion claim accrued and specifically addressed the situation presented in this case:
For example, if a chattel is placed in possession of a bailor, and the bailor secretly sells the chattel to a third person, thereby converting it, the true owner has no reason to know of the conversion. In such cases, the cause of action must accrue after some type of notice of the conversion has occurred. If the cause of action accrued upon the acts of conversion, as appellant argues, the parties in lawful possession of property would be in a position to secretly and unlawfully acquire or transfer ownership rights through conversion. If the cause of action accrued upon demand and refusal, the plaintiff could indefinitely suspend the statute of limitations, a result substantive limitations law does not permit.
We therefore hold that the proper rule of accrual for conversion actions in cases in which possession is initially lawful and demand and refusal is useless, or unequivocal acts of conversion have occurred, is that the cause of action accrues upon demand and refusal, or discovery of facts supporting the cause of action, whichever occurs first.
Id.

*702
Wells Fargo argues the discovery rule should not apply to RPK’s conversion claim because Wells Fargo’s possession was initially unlawful and RPK’s injury was not inherently undiscov-erable. We disagree. The discovery rule is a very limited exception to statutes of limitations, and applies only when the nature of the plaintiffs injury is inherently undiscoverable and the evidence of injury is objectively verifiable.
BP Am. Prod. Co. v. Marshall,
We conclude the category of conversion cases in which a lessee lawfully in possession of a lessor’s property secretly sells or transfers the lessor’s property to a third party, but continues to comply with its obligations under the lease, involves injury that is both inherently undis-coverable and objectively verifiable. The discovery rule is applicable to this category of cases regardless of whether the defendant is the lessee who transferred the property or the person currently in possession of the property.
See Childs v. Haussecker,
In this case, a lessee, ATA, was in lawful possession of property owned by the lessor, RPK. Without notifying RPK, ATA transferred the property to a third person, FINOVA, and FINOVA transferred the property, through Talos, to Wells Fargo. ATA, however, continued to comply with its contractual obligations by paying the amounts owed under the lease and by providing RPK with proof of insurance and records relating to the thrust reverser. After ATA rejected the lease in the 2008 bankruptcy, RPK learned that ATA no longer had the thrust reverser in its possession. At this point, RPK’s claim for conversion accrued. RPK filed suit within two years of the accrual of its claim. We *703 conclude the trial court did not err by concluding RPK’s conversion claim is not barred by the statute of limitations. We resolve Wells Fargo’s first issue against it.
Buyer in Ordinary Course
In its second issue, Wells Fargo asserts the trial court erred by awarding RPK possession of the thrust reverser because, pursuant to the business and commerce code, Wells Fargo had superior title to the thrust reverser. Wells Fargo specifically argues the thrust reverser was an accession to the aircraft purchased by Wells Fargo and that Wells Fargo purchased the aircraft in the ordinary course of business.
Contracts relating to the lease of goods are governed by article 2A of the Uniform Commercial Code (UCC), adopted in Texas as chapter 2A of the business and commerce code. Tex. Bus. & Com.Code Ann. §§ 2A.101, 2A.102 (West 2009). Other than exceptions not applicable to this case, under the UCC, a “good” includes “all things that are moveable at the time of identification to the lease contract.” Id. § 2A.103(a)(8). Generally, a buyer from the lessee of goods under an existing lease contract obtains, to the extent of the interest transferred, the leasehold interest in the goods that the lessee had or had power to transfer. Id. § 2A.305(a).
A leased good becomes an “accession” when it is installed in or affixed to other goods. Id. § 2A.310(a). Generally, the interest of a lessor under a lease contract that was entered into before the good became an accession is superior to all interests in the whole. Id. § 2A.310(b). However, the interest of a lessor under a lease contract entered into before the good became an accession is subordinate to the interest of a buyer in the ordinary course of business of any interest in the whole acquired after the good became an accession. Id. § 2A.310(d)(l). A buyer in the ordinary course of business is:
a person who in good faith and without knowledge that the sale to him or her is in violation of the ownership rights or security interest or leasehold interest of a third party in the goods buys in the ordinary course from a person in the business of selling goods of that kind but does not include a pawnbroker.
Id. § 2A.103(a)(l). Comment (a) to section 2A.103, relating to buyer in the ordinary course of business, refers to “Section 1-201(9).” Section 1.201(b)(9) of the business and commerce codes states, in relevant part:
“Buyer in ordinary course of business” means a person that buys goods in good faith, without knowledge that the sale violates the rights of another person in the goods, and in the ordinary course from a person, other than a pawnbroker, in the business of selling goods of that kind. A person buys in the ordinary course if the sale to the person comports with the usual or customary practices in the kind of business in which the seller is engaged or with the seller’s own usual or customary practice.
Tex. Bus. & Com.Code Ann. § 1.201(9) (West 2009). Buying a good from inventory generally satisfies the requirements that buying be in ordinary course and the seller be in the business of selling such goods.
In re Winn’s Stores, Inc.,
We turn first to the issue of whether Wells Fargo was a buyer in the ordinary course of business, an affirmative defense on which Wells Fargo had the burden of proof.
See THPD, Inc. v. Cont’l Imports, Inc.,
A liquidation can be a sale that does not qualify as being in the ordinary course of business.
See Sindone v. Farber,
In addition to the parties’ stipulations, the trial court also admitted into evidence the parties’ joint exhibit 4, FINOVA’s June 13, 2001 disclosure statement in the bankruptcy proceedings, and the parties’ joint exhibit 49, FINOVA’s Form 10-Q for the quarter ending June 30, 2008. In the disclosure statement, FINOVA stated a new $6,000,000,000 loan, cash on hand, and $3,260,000,000 in New Senior Notes would enable the debtors to restructure their debt. In the Form 10-Q, FINOVA stated:
Since emergence from chapter 11 bankruptcy proceedings in August 2001, our business activities have been limited to maximizing the value of our portfolio through the orderly collection of our assets. These activities included collection efforts pursuant to underlying contractual terms, negotiation of prepayments and sales of assets or collateral. We have substantially completed the liquidation of our portfolio and our focus has shifted to the continued wind down of our operations and future dissolution of our entities. We are prohibited by the Indenture (the “Indenture”) governing our 7.5% Senior Secured Notes (the “Senior Notes”) from engaging in any new lending activities or other business. Any funds generated in excess of cash reserves permitted by our debt agreements have been used to reduce obligations to our creditors.
FINOVA noted that it “clearly [did] not have sufficient assets to fully repay the Senior Note obligation.” FINOVA stated it recognized before April 1, 2005 that it would not be able to repay the Senior Notes in full and, therefore, sought relief from the bankruptcy court regarding distributions to stockholders.
Wells Fargo asserts that FINOVA’s pre-bankruptcy business involved the financing and leasing of aircraft and that FINOVA sold a substantial number of aircraft to third parties at the end of the lease terms applicable to the aircraft. Therefore, Wells Fargo argues, the sale of
*705
the aircraft in this case was done in the ordinary court of FINOVA’s business. However, after emerging from bankruptcy in 2001, FINOVA’s only “business” was liquidating its remaining assets. Regardless of whether the sale of the aircraft could have been a sale in the ordinary course of FINOVA’s pre-bankruptcy leasing and financing business, FINOVA did not have an ongoing business post-bankruptcy involving the leasing of goods and was prohibited by the Senior Notes from engaging in new lending activities or other business. After emerging from bankruptcy, FINOVA no longer actively engaged in leasing or selling goods as part of an ongoing business.
See
Tex. Bus. & Com.Code Ann. §§ 1.201(9), 2A.103(a)(l);
In re Winn,
We conclude the trial court did not err by determining that FINOVA, post-bankruptcy, was not engaged in the leasing of aircraft or in the sale of aircraft incidental to FINOVA’s leasing and financing business. The trial court also did not err by concluding that FINOVA’s sale of the aircraft at issue in this case as part of FINO-VA’s liquidation of all its assets was not a sale in the ordinary course of business.
See Sindone,
Damages
In its third through sixth issues, Wells Fargo contends the trial court erred in awarding damages to RPK because (1) there was no evidence that Wells Fargo caused the delamination in the thrust reverser; (2) there was no evidence to support the damage award for lost profits because RPK’s expert’s testimony was unreliable; and (3) even if RPK’s expert’s testimony about lost profits was reliable, it does not support the damages awarded for past and future lost profits.
Standard of Review
A party challenging the legal sufficiency of the evidence to support a finding on an issue for which it did not have the burden of proof at trial must show there is no evidence to support the adverse finding.
Exxon Corp. v. Emerald Oil & Gas Co., L.C.,
*706 Damages for Defect
In its third issue, Wells Fargo asserts the trial court erred by awarding $350,000 for the cost to repair the delamination on the thrust reverser because there is no evidence Wells Fargo caused the delami-nation. RPK contends that, under the terms of the lease, it was entitled to the return of the thrust reverser in a serviceable condition when the lease either expired or was terminated. Alternatively, RPK contends the unserviceable condition of the thrust reverser was a direct consequence of having NORDAM inspect the part at a time when it was not scheduled for inspection and was not required to be inspected by any maintenance program applicable to the aircraft.
The trial court found that, due to the delamination, the thrust reverser had been declared unserviceable and the cost to repair the thrust reverser is $350,000. It also found the delamination was discovered during the NORDAM inspection and that the inspection was not required by the lease or the maintenance plan for the aircraft. It concluded:
Because RPK is entitled to a Thrust Reverser in serviceable condition pursuant to the Engine Lease and Wells Fargo’s possession of the Thrust Reverser is subject to RPK’s rights under the Engine Lease, RPK is entitled to repair damages from Wells Fargo in an amount of $350,000 to return the Thrust Reverser to serviceable condition.
Although the trial court made no conclusion of law regarding whether RPK was entitled to damages for the cost of repair due to Wells Fargo’s decision to have NORDAM inspect the thrust reverser, we will consider whether the award of damages can be affirmed on this basis.
See OAIC Commercial Assets, L.L.C.,
A plaintiff must prove damages before recovery is allowed for conversion.
Deaton,
In its second amended petition, RPK sought as damages for its conversion claim “lost use of the Thrust Reverser, lost profits, lost value, and attorneys’ fees.”
6
*707
It did not elect to recover damages based on the fair market value of the purportedly undamaged thrust reverser as of the date of the conversion. Based on the remedy it elected, RPK was entitled to the return of the thrust reverser and any proven damages for lost use during the time of the conversion.
Wiese,
John Berry Milson, who works with the financial technical practice at SH & E, a consulting firm retained by RPK, testified delamination is caused by moisture seeping into small areas of disbonding on a part. As the moisture freezes and expands, more of the panel will “break away.” There was evidence that inspections of the thrust reverser prior to the NORDAM inspection did not detect the delamination. However, all witnesses who testified about the delamination stated there was no way to determine when the delamination occurred. Wells Fargo’s discovery of the delamination during the period of conversion did not establish the dela-mination process began, rather than just continued, during the period of the conversion.
There was no evidence the delamination was a natural and proximate result of Wells Fargo’s conversion of the thrust reverser.
See First State Bank, N.A. v. Morse,
We next turn to the trial court’s conclusion that Wells Fargo was bound by the terms of the lease to return the thrust reverser in a serviceable condition and, therefore, must pay the cost to repair the delamination. RPK relies on section 2A.305(a) of the business and commerce code to support its argument that Wells Fargo is bound under the lease between RPK and ATA. Section 2A.305(a) states that, subject to provisions not applicable in this case, “a buyer or sublessee from the lessee of goods under an existing lease contract obtains, to the extent of the interest transferred, the leasehold interest in the goods that the lessee had or had power to transfer” and “takes subject to the existing lease contract.” Tex. Bus. & Com. Code Ann. § 2A.305(a). As set out above, we agree with RPK that Wells Fargo did not receive title to the thrust reverser, but took it subject to RPK’s ownership interest.
See id.
However, section 2A.305(a) addresses only the issue of title as it pertains to the sale or sublease of an item subject to an existing lease. It does not statutorily bind the buyer or sublessee of the item to the lease terms.
See id.
Section 2A.305(a) of the business and commerce code does not require Wells Fargo to comply -with the terms of the lease between RPK and ATA about which Wells Fargo had no knowledge.
See Jones v. Cooper Indus., Inc.,
*708 The trial court erroneously concluded RPK could recover the cost to repair the thrust reverser from Wells Fargo based on RPK’s conversion claim. We resolve Wells Fargo’s third issue in its favor and render judgment that RPK take nothing on its claim for cost to repair the thrust reverser.
Lost Profits
In its fourth issue, Wells Fargo argues the trial court erred by awarding damages for RPK’s lost profits because the only evidence offered to support these damages was the testimony of RPK’s expert witness, Ken De Jaeger. Wells Fargo complains De Jaeger’s methodology was flawed and his testimony was unreliable and, therefore, there was essentially no evidence to support the trial court’s award of lost profits.
Applicable Facts
De Jaeger testified he works in SH & E’s Financial Technical Services Group. He has a masters of business administration degree and is a certified appraiser with the International Society of Transport Aircraft Trading Appraisal Program (IS-TAT). He was certified as an appraiser by ISTAT in 1997 and as a senior appraiser in 2008. His field of expertise is appraisal and asset management. Asset management involves the buying, selling, and leasing of aircraft and related parts. He provides appraisals, remarkets aircraft, helps airlines purchase aircraft, performs maintenance reviews of airlines, and prepares industry reports. He appraises anything aviation-related, including spare parts such as thrust reversers. He was retained by RPK to provide a diminution in value of the thrust reverser and damages relating to loss of use and lost profits.
De Jaeger testified aviation industry data concerning the sale and lease of spare parts, such as thrust reversers, is “very limited.” Only a “few people” buy and sell thrust reversers because they are very expensive and are “long-lifed” assets. The part stays “on wing” for a long time and demand for the part is very sporadic. Moreover, data concerning sales and leases of thrust reversers is generally deemed confidential by those involved in the transactions.
De Jaeger testified the lease between ATA and RPK for the thrust reverser was a “leverage lease.” A leverage lease is typically a long-term financing arrangement used for new, “high dollar” equipment. A leverage lease involves nonrecourse lenders and tax benefits to the lessee. A leverage lease involving a thrust reverser is not common and there is not currently a leverage lease market in the United States for thrust reversers.
De Jaeger performed a current market value analysis in this case to determine the market value and the lease rate for the thrust reverser. To conduct such an analysis, he researches the market, determines the current market value of the asset through an internal SH & E database, looks at how many of those assets are for sale or lease in the market, and determines a value. De Jaeger testified he first searched SH & E’s internal database for thrust reversers. SH & E’s internal database contains appraisals on over eight million parts. However, the only appraisals for thrust reversers contained in the database were too old to be relevant.
De Jaeger then researched the Inventory Locator Service (ILS), a database that many parties use to list spare parts for sale. He first checked the ILS for thrust reversers when ATA declared bankruptcy in April 2008, and determined there were no thrust reversers on the market at that time. He checked the ILS in July 2009 when he prepared his first report and, *709 again, there were no thrust reversers on the market. He cheeked the ILS for a third time in February 2010, just prior to trial, and determined there were ten thrust reversers on the market. De Jae-ger believed the market had changed due to the economy and some aircraft “being parted out.”
De Jaeger also contacted people he knew that either operated the “757” aircraft at issue in this case, overhauled 757 thrust reversers, or had 757 spare parts to sell “from time to time.” Although he contacted over twenty people, not everyone responded. Of those responding, Willis Lease indicated an overhauled thrust reverser had a market value between $1.2 and $1.5 million and a serviceable thrust reverser had a value between $600,000 and $1,000,000. Flight Director indicated an overhauled thrust reverser had a value between $1.3 and $1.5 million and provided lease rates of $30,000 to $35,000 for sixty to ninety days and stated there could be sporadic long-term leases of thrust rever-sers in the amount of $15,000 to $20,000 per month. He received a total of seven to ten “data points” and believed they were all “in line” with Willis Lease and Flight Director. De Jaeger did not indicate how many of the data points related to the market value of a thrust reverser as opposed to lease rates.
The trial court admitted into evidence a compilation of email responses that De Jaeger received relating to his inquiries. The emails reflect De Jaeger and other individuals employed by SH & E contacted outside companies regarding the market value and lease rates of thrust reversers. Many of the emails detailed to De Jaeger conversations the other SH & E employees had with employees of the outside companies. As to lease rates, the emails indicate Ashley Cooper from TES stated thrust reversers rented on an AOG basis at $3,000 per day per half. 7 Nick Dodd indicated TEMCO Canada had never leased a thrust reverser separately from an aircraft engine, but he would “expect” the lease rate would be $2,000 to $3,000 per day per half. “Graeme from Willis” had “no clue” about lease rates for thrust reversers. According to Elizabeth Morgan at FDI, thrust reversers were “swapped out no more than 4x/year (90 days typical) and are generally fully utilized.” However, Steve Horner, of an unidentified company, stated the thrust reverser market “has eased w/certain lessors having availability.” A “Manager-Flight Controls & Thrust Reversers of a U.S. based aviation large equipment lessor” indicated a typical lease rate was $30,000 to $35,000 per month, exclusive of recertification fees. De Jaeger testified he could not obtain leases or contracts to support the data because this information is confidential. He also could not provide information on the entities that bought or sold thrust reversers. De Jaeger admitted that leases of thrust reversers have a range of rental rates that vary depending on factors such as the location of the party leasing the thrust reverser, who operates the thrust reverser, how the thrust reverser is maintained, the environment, the length of the lease, and the number of thrust rever-sers on the market.
De Jaeger opined that RPK would incur expenses of $20,000 to draft an initial thrust reverser lease and seventy-five percent of that cost for each subsequent lease. It would also incur administrative expenses of $10,000 and initial legal expenses of $5,000. De Jaeger used a medium term lease rate of $35,000 per month for a sixty to ninety day period and an AOG daily *710 lease rate of $5,000. Using a mixture of the medium term and AOG lease rates with varying remarketing periods between leases and subtracting the related expenses, De Jaeger opined that RPK suffered $498,480 in lost profits between April 2, 2008 and March 1, 2010 if the thrust reverser had been returned to RPK in serviceable condition. If RPK was required to repair the thrust reverser, RPK suffered $149,521 in lost profits over the same period of time.
The trial court found (1) the typical medium term lease rate for a thrust reverser in May 2008 was $35,000 per month, (2) the typical medium term lease rate for a thrust reverser at the time of trial was $30,000 per month, (3) the typical short term market lease rate at the time of trial was $5,000 per day, and (4) RPK had suffered $498,480 in lost profits from the loss of use of the thrust reverser. The trial court concluded the “testimony of Plaintiffs’ expert witness Kenneth De Jaeger, as a matter of law, satisfies the standard for the recovery of lost profits under Texas law” and awarded RPK $498,480 for past lost profits and $30,000 per month, commencing immediately, for so long as Wells Fargo retained possession of the thrust reverser.

Here, De Jaeger testified his usual methodology in valuing an asset involved researching the market, determining the current market value through SH & E’s internal database, and looking at how many of the asset were for sale or lease. De Jaeger admitted, however, that there was no relevant information in SH & E’s database about lease rates for thrust reversers and the ILS contained no information on lease rates for thrust reversers in April 2008 or in July 2009. 8 Accordingly, De Jaeger could not use two of the prongs of his stated methodology. De Jaeger’s opinions about the lease rate for a thrust reverser were premised entirely on “market research” consisting of data that was collected by word of mouth from a few people employed by companies in the aviation industry. De Jaeger could not verify the information obtained based on review of contracts or leases because the contracts and leases were deemed confidential. He could not identify some of the individuals on whose verbal opinions he relied or the companies that purportedly leased thrust reversers at the rental rates included in his analysis. At least one of the individuals contacted by De Jaeger had no experience in leasing thrust reversers and offered a lease rate based purely on speculation.
Without any documentary evidence to support the information provided by his contacts in the industry, De Jaeger took the lease rates provided by these individuals and, without explaining his analytical basis, assumed a mixture of medium term leases and AOG leases interspersed with what appears to be arbitrary remark-eting periods. De Jaeger failed to identify any specific lease that was available to or was lost by RPK. The trial court had nothing more than De Jaeger’s opinion that RPK could have located and entered into the assumed leases that formed the basis of De Jaeger’s opinion. “[T]he bare assertion that contracts were lost does not demonstrate a reasonably certain objective

determination of lost profits.”
Holt,
De Jaeger is qualified to render expert testimony on the sale and leasing of aircraft parts. Opinions concerning lost profits may be competent evidence, if the opinion is based on objective facts, figures, or data from which the amount of lost profits may be ascertained.
KMG Kanal-Muller-Gruppe Deutschland GmbH & Co. v. Davis,
In its fifth and sixth issues, Wells Fargo complains that, even if De Jaeger’s testimony was reliable, the trial court erred by awarding RPK damages for past profits of $498,480 and for future loss of use of $30,000 per month until the thrust reverser was returned because De Jaeger’s testimony does not support these awards. Due to our resolution of Wells Fargo’s fourth issue, we need not address these complaints.
See
Tex.R.App. P. 47.1. We render judgment that RPK take nothing on its claim for past and future loss of use of the thrust reverser.
See Deaton,
Attorney’s Fees
In its seventh issue, Wells Fargo asserts the trial court erred by awarding RPK attorneys’ fees because it erred in granting RPK a declaratory judgment. The trial court concluded the “attorneys’ fees and expenses incurred by RPK in the prosecution of its claims were reasonable and necessary. Therefore, RPK is entitled to recover all of its attorneys’ fees and expenses incurred in the prosecution of this matter.” We first note that RPK sought to recover attorneys’ fees both under its claim for conversion and pursuant to its request for a declaratory judgment and the trial court awarded all fees incurred by RPK in the prosecution of its “claims.”
On this record, we cannot determine on what basis the trial court awarded attorneys’ fees or whether there was a sufficient basis to support declaratory relief separate from the conversion claim.
See Etan,
Conclusion
We affirm the trial court’s conclusions that (1) RPK’s conversion claim is not barred by the statute of limitations and (2) Wells Fargo did not receive title to the thrust reverser as a buyer in the ordinary course of business under the UCC. On its conversion claim, RPK elected to recover possession of the thrust reverser and lost profits, rather than the fair market value of the thrust reverser at the time of the conversion. We conclude there is no evidence that the delamination of the thrust reverser was a natural and proximate result of Wells Fargo’s conversion. We further conclude RPK’s expert’s testimony failed to establish RPK’s lost profits with reasonable certainty. We, therefore, reverse the portion of the trial court’s judgment awarding RPK damages for cost to repair the thrust reverser and for past and future lost profits and render judgment RPK take nothing on its damages claim. We affirm the trial court’s judgment awarding possession of the thrust reverser to RPK. We reverse and remand the trial court’s award of attorney’s fees to RPK for further proceedings consistent with this opinion.
Notes
. Although not included in the stipulated facts, both parties represent on appeal that a thrust reverser is a piece of equipment that is used to help slow an aircraft upon landing.
. We recognize the thrust reverser is actually two pieces of equipment, one designed to fit under the left wing and the other designed to fit under the right wing of the aircraft. However, in its findings of fact and conclusions of law, the trial court referred to this equipment as a single "thrust reverser” and, for consistency, we will also utilize that terminology in this opinion.
. Although not contained in the parties’ stipulations, the record reflects delamination is the separation of the thin metal skin of the thrust reverser from the base underneath it.
. See
also Ayers v. Greater Houston Pipe, L.C.,
No. 01-98-01022-CV,
. We recognize that when the trial court’s judgment rests upon the specific grounds set out in the findings of fact and conclusions of law, we are not permitted to assume omitted findings or conclusions necessary to any other grounds for the judgment.
See Leonard v. Eskew,
. At trial, the "lost value” sought by RPK was the cost to repair the delamination on the thrust reverser and the impact of the delami- *707 nation on the market value of the thrust re-versen
. De Jaeger testified that an AOG or “aircraft on the ground lease” is a short term lease for an interim replacement while a failed part is being repaired.
. De Jaeger testified the ILS contained information on ten thrust reversers in February 2010. However, he did not state whether these thrust reversers were for sale or for lease or the lease rate for any thrust reverser in February 2010. There was also no indication that De Jaeger relied on any information available in February 2010 to support his opinion regarding the profits lost by RPK in 2008 and 2009.
