Before EDMONDS, Presiding Judge, and ARMSTRONG and KISTLER, Judges.
KISTLER, J.
The trial court ruled that plaintiff's insurer was subrogated to plaintiff's negligence claim. The court accordingly ordered that the insurer be added as a named plaintiff in this action. The case proceeded to trial, and the jury returned a verdict in defendant's favor. Plaintiffs appeal, challenging the trial court's subrogation ruling. We reverse and remand.
Continental Insurance Company insured plaintiff, Growers Refrigeration Co., Inc. When a fire destroyed Growers' cold storage facility, Continental issued progress payments to Growers for its losses. Growers signed a receipt for the payments, which both stated that Growers was subrogating Continental to any claim it might have and also authorized Continental to file an action in Growers' name.
Growers filed a negligence action against defendant. In its answer, defendant alleged that Growers was not the real party in interest because Continental had paid Growers for its loss and had become subrogated to its rights. Several months after defendant filed its answer, Growers and Continental executed a loan receipt stating that the payments Growers had received were a loan. Continental also filed a ratification of Growers' action against defendant pursuant to ORCP 26 A.
The trial court found that Growers intended to subrogate Continental to its claims. The court concluded that neither the later executed loan receipt nor the ratification was sufficient to change that finding. It accordingly ruled that Continental should be named as a plaintiff, along with Growers, in this action. The jury returned a verdict in favor of defendant. Growers and Continental appeal from the resulting judgment.
The Oregon Supreme Court has long recognized that an insurer who makes payments to its insured and receives a loan receipt in return does not become subrogated to its insured's claims. Waterway Terminals v. P.S. Lord, 242 Or. 1, 7-8, 406 P.2d 556 (1965); Furrer v. Yew Creek Logging Co., 206 Or. 382, 389-90, 292 P.2d 499 (1956). Defendant acknowledges those cases but argues that they apply only when the loan receipt is executed contemporaneously with the payments. Defendant reasons that because the loan receipt in this case was executed long after Continental had made the progress payments to Growers, the loan receipt does not reflect their true relationship.
The Supreme Court held in Waterway Terminals that a later executed loan receipt is controlling even though the insurer has previously issued its insured drafts "purport[ing] on their face to be in full payment of the loss." 242 Or. at 8, 406 P.2d 556. We made the same point more explicitly in Northern Ins. Co. v. Conn Organ, 40 Or.App. 785, 796-97, 596 P.2d 605 (1979):
"[T]he existence of evidence that the transaction was not intended from the outset to be a loan or was not consistently treated as such is not conclusive. In Waterway Terminals there was such evidence, but the court held as a matter of law the loan receipt was controlling. We do not think this case can be meaningfully distinguished. Once the Supreme Court was persuaded to accept the form of a loan receipt as being the substance of the transaction, *523 it had entered upon a course of logic that led inevitably to the Waterway Terminals conclusion."[1] (Emphasis in original).
To paraphrase our earlier decision in Northern Ins. Co., we do not think this case can be meaningfully distinguished from either that case or Waterway Terminals. Where, as here, defendant's limited interest in the relationship between Growers and Continental assurance that it will be required to defend against this claim only onceis protected, the loan receipt is controlling. See Northern Ins. Co., 40 Or.App. at 797, 596 P.2d 605; accord ORCP 26 A. Not only did the loan receipt preserve sole title to the cause of action in Growers' name, but the introduction of plaintiff's insurer into this case was prejudicial error even with the trial court's limiting instruction. See Waterway Terminals, 242 Or. at 38, 406 P.2d 556 (instruction not sufficient to cure prejudice resulting from the introduction of plaintiff's insurance coverage).[2]
Reversed and remanded for new trial.
NOTES
[1]  We reached this conclusion in Northern Ins. Co. even though the trial court in that case had found that "the parties' intention was contrary to that expressed in the loan receipts." 40 Or.App. at 796, 596 P.2d 605.
[2]  Because it is not clear that the issue will arise on remand, there is no need to resolve the issue raised by plaintiffs' second assignment of error whether plaintiffs presented a sufficient basis to the trial court to support their requested negligence per se instruction. See Shahtout v. Emco Garbage Co., 298 Or. 598, 605, 695 P.2d 897 (1985) (defining the trial court's role in determining when such an instruction should be given).
