When one payee indorses a check that is payable jointly to two payees, and a bank pays the indorsing payee without the other’s consent, Article 3 of the Arkansas Uniform Commercial Code provides that the bank is liable for conversion to the non-consenting payee. In this situation, “the measure of liability is presumed to be the amount payable on the instrument.” Aek. Code Ann. § 4-3-420(b) (emphasis added). The appeal in this diversity case raises the difficult question whether the bank’s liability under Arkansas law is limited to the actual harm to the co-payee caused by the conversion. The district court granted summary judgment for the aggrieved co-payee, concluding the defendant bank must pay the face amount of the converted checks. We conclude the Supreme Court of Arkansas would limit plaintiffs recovery to its actual damages and therefore reverse.
*535 I.
In June 1999, American State Bank (ASB) of Craighead County, Arkansas granted a $425,000 revolving line of credit to the Womack & Womack Partnership, secured by liens on the Partnership’s crops and on agricultural subsidy payments it received. Between October 1999 and April 2000, partner Ricky Womack indorsed twenty-four checks totaling $262,330.76 and deposited the proceeds in the Partnership’s account with Union Planters Bank (UPB) of Shelby County, Tennessee. Each check was jointly payable to the Partnership and ASB, reflecting ASB’s hens, but UPB paid the checks on Ricky’s sole indorsement, without ASB’s knowledge or consent. Ricky then withdrew the proceeds from the Partnership account and lost the money gambling. When ASB discovered the unauthorized deposits in May 2000, it sued UPB for conversion in Arkansas state court. UPB removed the case to federal court, invoking the court’s diversity jurisdiction.
ASB moved for summary judgment. In response, UPB presented evidence that, after discovering Ricky’s misconduct, ASB made over $200,000 of additional advances to the Partnership — now controlled by Ricky’s brother' — -and extended the term of its secured loan from March 2001 to March 2002. Since then, the Partnership has remained current on its crop loan payments and — as of January 2002 — -had paid the loan down to $255,093.56. The district court nevertheless granted summary judgment awarding ASB the face amount of the converted checks. On appeal, UPB concedes that it is liable to ASB for conversion under § 3-420(a) of the Arkansas UCC.

But UPB argues that its liability under § 3^120(b) should be limited to ASB’s actual damages, and that genuine issues of material fact preclude the grant of summary judgment on the damages issue.
See
Fed. R. Civ. P. 56(c). Reviewing these issues
de novo,
we agree.
See Brookins v. Int’l Motor Contest Ass’n,
II.
The issue on appeal is whether ASB may recover the face amount of the converted checks as a matter of law, despite evidence that the actual harm to ASB from the conversion may be a lesser amount. In other words, would UPB’s evidence of reduced actual harm, if believed, be legally sufficient to rebut the presumption in § 3-420(b) that UPB is liable for the face amount of the checks?
In construing the presumption, we encounter two distinct issues to which it may apply. The first concerns the value of the converted checks. “Ordinarily, the proper measure of damages for conversion of property is the market value of the property at the time and place of its conversion.”
McQuillan v. Mercedes-Benz Credit Corp.,
The second issue is broader — whether the conversion plaintiff may recover as damages the face amount of the instrument even if that amount exceeds the actual loss. The plain language of § 3^120(b) suggests that it also encompasses this issue. The statute provides that “the measure of liability is presumed to be the amount payable on the instrument,” not simply that “the value of the converted instrument” is presumed to be the amount payable on the instrument. But the statute and its Commentary give no guidance as to how the presumption should be applied to this issue. The UCC simply defines “presumed” to mean that “the trier of fact must find the existence of the fact presumed unless and until evidence is introduced which would support a finding of its nonexistence.” ARK. Code. ANN. § 4-1-201.
ASB argues that “[t]he law is silent in Arkansas but clear elsewhere: UPB can rebut the damages presumption and mitigate its damages if it can prove ASB actually received the proceeds of the 24 wrongfully paid checks.” ASB cites two diversity cases to this effect,
D & G Equip. Co. v. First Nat’l Bank of Greencastle, Pa.,
We have two problems with this conclusion. First, the decisions on which the district court relied construed the
irrebuttable
presumption that applied to actions against drawee banks under the former UCC provision.
See
U.C.C. § 4-319(2) (1966) (“the measure of the drawee’s liability is the face amount of the instrument. In any other action ... the measure of liability is presumed to be the face amount of the instrument.”). Even under this provision, UPB as a depositary bank would have been entitled to rebut the presumption.

Second, UPB cites cases from other
*537
States that limited a bank’s conversion liability, even under the irrebuttable presumption, to the plaintiffs actual loss, if the loss was less than the value of the converted instruments.
See Pomar Enters., Inc. v. First State Bank of E. Detroit,
From this array of conflicting cases, we conclude there is no “prevailing view” as to whether a bank’s liability is limited to the plaintiffs actual loss, despite the presumption in § 3-420(b). Rather, courts applying the UCC have determined when and how the presumption may be rebutted in accordance with more general state law damage principles, which of course vary from State to State. Thus, to determine how the Supreme Court of Arkansas would decide the issue presented by this appeal, we turn our focus to the Arkansas law of damages for conversion.
Our inquiry begins with
Starkey Constr., Inc. v. Eicon, Inc.,
Starkey teaches that the § 3^420(b) presumption may be rebutted by evidence that the proceeds of converted checks in fact found their way to the intended recipients). But that does not resolve the issue in this case. Ricky Womack squandered the proceeds wrongfully deposited in the Partnership’s account. UPB’s evidence is that ASB has received other money from the Partnership that reduced its actual loss from the conversion. In our view, whether those later payments should be *538 credited against UPB’s conversion liability is an issue properly resolved by reference to the Arkansas damage law principle known as the collateral source rule:
This Court has defined the collateral source rule as a general rule that [a plaintiffs] recoveries from collateral sources do not redound to the benefit of a tortfeasor, even though double recovery for the same damage by the injured party may result. However, for the collateral source rule to pertain, the third-party payment must be wholly independent of the tortfeasor.
Douglas v. Adams Trucking Co.,
On this record, we cannot say as a matter of law that payments by the Partnership reducing ASB’s line-of-credit loan were from an independent collateral source. In the first place, the Partnership was the co-payee on the converted checks. When Ricky Womack indorsed the checks and deposited them in the Partnership account at UPB, he was acting as the Partnership’s agent. Thus, the Partnership, too, is likely liable to ASB for conversion.
See
Aek. Code Ann. §§ 4-3-402(a) and the first sentence of § 3-420(a). In general, “payments made by another who is, or believes he is, subject to the same tort liability” are credited against a tortfeasor’s liability. Restatement (Seoond) Of ToRts § 920A(1), a section of the Restatement cited for guidance in
Montgomery Ward & Co. v. Anderson,
For the foregoing reasons, the judgment of the district court is reversed and the case is remanded for further proceedings not inconsistent with this opinion.
Notes
. The Uniform Commercial Code Commentary confirms that UPB is liable for conversion:
[Section 3-420(a)] covers cases in which an instrument is payable to two persons [who] are not alternative payees .... Under Section 3-110(d) the check can be negotiated or enforced only by both persons acting jointly. Thus, neither payee acting without the consent of the other, is a person entitled to enforce the instrument. If [only one payee] indorses the check [and] Depositary Bank takes the check for deposit to [the indorsing payee’s account], Depositary Bank is liable to [the other payee] for conversion of the check if she did not consent to the transaction.
Ark.Code of 1987 Ann., Commentaries Vol. A, Comment to § 3-420 (A.C.A. § 4-3-420) n. 1.
. The current UCC § 3-420(b) replaced former § 3-419(2) in the 1990 revision to Article 3, which was enacted in Arkansas in 1991.
. The UCC Commentary explains that the ir-rebuttable presumption was deleted “because it is not clear why the former law distinguished between the liability of the drawee and that of other converters.”
See Ark.Code of 1987 Ann., Commentaries Vol. A,
Comment to § 3-420 (A.C.A. § 4-3-420) n.2. That explanation seems to understate the extent of the change, because under the UCC a depositary or collecting bank (like UPB in this case) was liable to the drawee bank for breach of warranty and therefore had to indemnify the drawee bank for its liability under the former irrebuttable presumption.
