OPINION
The case arises from a stock sale transaction, and we are asked to decide whether appellants are entitled to reformation or rescission of the transaction because two vacant lots were transferred in the stock sale. Appellant SCI Minnesota Funeral Services, Inc. (SCI) sold Crystal Lake Cemetery Association (Crystal Lake) to appellant Corinthian Enterprises, LLC (Corinthian) in a stock sale agreement. Corinthian subsequently sold and assigned Crystal Lake to respondent Washburn-McReavy Funeral Corporation (Washburn) in a share purchase agreement. SCI and Corinthian brought this action contending the parties did not intend to include the vacant lots in the sale of Crystal Lake, and they sought equitable relief to remedy this claimed mistake. The district court held that SCI and Corinthian were not entitled to reformation or rescission based on mutual mistake, and the court of appeals affirmed. SCI Minn. Funeral Servs., Inc. v. Washburn-McReavy Funeral Corp.,
Although no one involved in the transaction was aware of it, Crystal Lake’s assets also included the two vacant lots at issue here. One lot is located in Colorado and one lot is located in Burnsville. SCI either acquired or purchased the vacant lots for Crystal Lake several years prior to the Crystal Lake sale. A former employee of SCI testified that SCI purchased the Colorado land in the late 1990s for tax purposes “as part of a like-kind exchange,” and it acquired the Burnsville land when it “had been carved out of the asset sale of another cemetery property years ago.” SCI continued to pay property taxes on the Colorado lot after the 2005 sale of Crystal Lake. The parties agree that the value of the two lots is approximately $2 million.
SCI and Corinthian agreed from the beginning of negotiations that they would structure the sale of Crystal Lake as a stock transaction based on their conclusion that Minnesota law prohibits the acquisition of cemeteries for profit.
On July 20, 2005, SCI and Corinthian reduced their agreement to writing and entered into a stock sale agreement. In the agreement, SCI agreed to sell all of its shares of Crystal Lake to Corinthian. The purchase price of the stock was $1 million. The stock sale agreement listеd the three cemeteries — Crystal Lake Cemetery, Dawn Valley, and Glen Haven — but it did not specifically mention the vacant lots. The agreement did provide, however, for the removal of some of Crystal Lake’s assets and operations. The agreement provided that SCI “shall and may cause to be removed” from the Crystal Lake sale all assets owned by Crystal Lake that are “not utilized in or related to the operation of the Business in its present form.”
Also on July 20, 2005, Corinthian entered into a share purchase agreement with Washburn in which Corinthian agreed to sell its outstanding shares of stock in Crystal Lake to Washburn for $1 million. In this agreement, Corinthian assignеd everything it received from SCI under the stock sale agreement to Washburn. The share purchase agreement listed the three cemeteries — Crystal Lake Cemetery, Dawn Valley, and Glen Haven — as transferring to Washburn.
The record is unclear about when SCI first learned that the Crystal Lake sale included the vacant lots. Washburn first became aware sometime in 2007 or 2008 that it owned the Colorado lot. This occurred when the chief executive officer of Washburn received a phone call from a potential purchaser inquiring about the Colorado property and when Washburn’s chief financial officer received a phone call from SCI requesting a quit claim deed for the property. Washburn did not become aware that it was the owner of the Burns-ville lot until this lawsuit was commenced.
SCI and Corinthian sued Washburn and requested several forms of equitable relief from the district court, including reformation of both agreements (the stock sale agreement and the share purchase agreement), and rescission. The parties each moved for summary judgment. The district court granted Washburn’s motion for summary judgment and denied appellants’ motion for summary judgment. The court held that it could not reform the agreements because the evidence did not satisfy the elements required for reformation. As for rescission, the court considered only the equitable remedy of rescission based on mutual mistake. The court, relying on Costello v. Sykes,
SCI and Corinthian appealed and a divided court of appeals affirmed. SCI Minn.,
We turn first to consideration of the proper standard of review that applies to the review of a grant of summary judgment involving claims for equitable relief. Appellants contend that the court of appeals incorrectly aрplied a manifestly-contrary-to-the-evidence standard to the district court’s determination of a request for reformation. Appellants also contend that the court of appeals incorrectly applied an abuse-of-discretion standard to the district court’s determination of a request for rescission. Appellants argue that we should apply a de novo standard of review because this case arose from summary judgment in which there were no disputed material facts.
For its part, Washburn argues that we should apply a de novo standard of review in determining whether the elements of reformation have been satisfied. But Washburn contends that the court of appeals correctly applied a deferential standard of review to the district court’s decision on equitable claims because we uphold the district court’s exercise of equitable powers unless they are manifestly contrary to the evidence, citing Metro Office Parks Co. v. Control Data Corp.,
In Citizens State Bank v. Raven Trading Partners, Inc., we discussed the applicable standard of review when reviewing a grant of summary judgment arising in the equity context.
As in Medica, we also conclude that a de novo standard of review applies to the questions at issue here. A deferential standard of review might be applicable where, after balancing the equities, the district court determines not to award equitable relief. See, e.g., Dieden v. Schmidt,
Here, the district court ruled as a matter of law that the requirements for rescission and reformation were not met. We review the court’s legal determinations de novo. See, e.g., Carlson v. Allstate Ins. Co.,
II.
We turn next to consideration of the district court’s conclusion that rescission was not available to appellants in this case. Rescission is an equitable remedy. See Nadeau v. Cnty. of Ramsey,
A.
Appellants first argue that they are entitled to rescission based on mutual mistake. The district court relied on Costello v. Sykes,
In Costello, the plaintiff purchased 10 shares of stock in the Calhoun State Bank from the defendant shareholders. Id. at 110,
The question presented in the case was “whether the mistake alleged is of such a character as to give rise to a right to rescind.” Id. at 111,
Costello bars rescission in this ease. Costello, like this case, involved the sale of stock. The parties’ intent, as reflected in thеir written agreement, was to transfer all of SCI’s stock in Crystal Lake to Corinthian and then to Washburn. Even if there was a mistake as to the value of the transaction, as appellants contend, under Costello we do not look behind the form of the transaction when the mistake is one of value. As we said in Costello, “[a] mistake relating merely to the attributes, quality, or value of the subject of a sale does not warrant rescission.”
If we conclude, as we have, that Costello bars the rescission claim, appellants urge us to overrule Costello. Based on the principle of stare decisis, “[w]e are ‘extremely reluctant to overrule our precedent ... ’ and ‘require a compelling reason’ to do so.” Zutz v. Nelson,
Contrary to appellants’ argument, in Costello itself, we suggested situations where rescission might be possible even in a stock sale. See
Appellants also rely on Clayburg v. Whitt,
Appellants contend that Clayburg supports their argument that we should look beyond the form of the transfer — a stock transaction — and look to the substance of the transfer — threе cemeteries — to determine whether appellants are entitled to rescission because the parties considered Crystal Lake’s assets and liabilities when negotiating the agreement. The dissent in the court of appeals agreed with the reasoning in Clayburg. SCI Minn.,
The Clayburg court adopted a rule different from our rule in Costello that rescission is not available in the stock sale context when the parties are mistaken about the extent of the assets of the corporation. But the analysis in Clayburg does not establish that the reasoning in Costello is unsound. See Zutz,
In sum, appellants have not presented any compelling reason for us to depart from our established precedent. Under that precedent, we hold that rescission does not apply in this case.
As an alternative to their mutual mistake argument, appellants argue that they are entitled to rescission due to a lack of mutual assent. Specifically, appellants contend there was no mutual assent between the parties when forming the stock sale agreement because there was only a “meeting of the minds” to sell, purchase, and transfer the cemeteries and not the vacant lots. The formation of sales contracts requires mutual assent among the pаrties involved in the transaction. HyVee Food Stores, Inc. v. Minn. Dep’t of Health,
When viewed under an objective standard, there was mutual assent to sell the Crystal Lake stock. The stock sale agreement clearly stated that “[SCI] does hereby agree to sell, transfer, assign and deliver ... all of the issued and outstanding shares of capital stock of [Crystal Lake] which are owned by [SCI].” In the context of a stock sale agreement, the law presumes that all assets and liabilities transfer with the stock. Cf. Specialized Tours, Inc. v. Hagen,
III. We turn next to consideration of appellants’ claim for reformation. Reformation is an equitable remedy that is available when a party seeks to alter or amend language in a contract so that the contract reflects the parties’ true intent when they entered into the contract. See Jablonski v. Mutual Serv. Cas. Ins. Co.,
We agree with appellants that Costello is not determinative of the reformation claim. While it is true, as Wash-burn argues, that appellants’ reformation and rescission claims are both grounded in mutual mistake, reformation and rescission are different forms of equitable relief. In reformation, a contract is modified to reflect the parties’ true intent, whereas in rescission, the entire contract is voidable. Compare Jablonski,
Instead, we apply our precedent setting forth the elements a plaintiff must prove to establish a prima facie case of reformation. A party seeking reformation must prove that: “(1) there was a valid agreement between the parties expressing their real intentions; (2) the written instrument failed to express the real intentions of the parties; and (3) this failure was due to a mutual mistake of the parties, or a unilateral mistake accompanied by fraud or inequitable conduct by the other party.” Nichols v. Shelard Nat’l Bank,
We conclude that appellants have not met the requirements for reformation as a matter of law. Even if appellants had satisfied the first element, appellants did not demonstrate that the agreements failed to express the parties’ true intentions, the second element, or that any such failure was due to a mutual mistake, the third element.
With respect to the second element, appellants contend that while the parties intended to transfer all of Crystal Lake’s assets through the stock sale, the parties made a mutual mistake because the stock sale agreement did not exclude the vacant lots from the transactions, and therefore the agreement did not reflect the parties’ true intentions. But the stock sale agreement gave SCI the right to exclude the vacant lots because these lots were not used in the cemetery business. Specifically, the language of the agreement provided
Appellants acknowledge that SCI could have excluded the vacant lots under this provision, but contend the provision is not dispositive because none of the partiеs was aware of the existence of the vacant lots. But under Minnesota law, when a business sells and transfers all of its stock, it is selling all of its assets and liabilities unless the business has expressed otherwise. Cf. Specialized Tours, Inc. v. Hagen,
With respect to the third element necessary for reformation, appellants’ claim also fails as a matter of law. The undisputed facts establish that appellants have not proven that the stock sale agreement failed to express the parties’ true intentions because of a mutual mistake. Any mistake here regarding the vacant lots was SCI’s mistake alone because it was SCI that failed to remove the lots from the transaction.
Appellants argue that SCI could not remove the lots because it was unaware of their existence. But under general corрorate law principles, “a corporation is charged with constructive knowledge ... of all material facts of which its officer or agent ... acquires knowledge while acting in the course of employment within the scope of his or her authority.” Travelers Indem. Co. v. Bloomington Steel & Supply Co.,
Because someone at SCI was aware of the existence of the vacant lots, and Minnesota law imputes this knowledge to the entire company, see Travelers,
In sum, the undisputed evidence establishes that appellants cannot prove that the stock sale agreement failed to express the true intentions of the parties because of a mutual mistake. We therefore hold that appellants аre not entitled to reformation.
Affirmed.
Notes
. Minnesota Statutes § 306.88, subd. 1 (2010), provides in relevant part that "[a] lodge, order, or association of a purely religious, charitable, or benevolent description, may acquire the cemetery properly of the cemetery association by gift or purchase and maintain and enlarge it if it ... does not operate for purposes of profit.”
. In the share purchase agreement, Corinthian also assigned any rights it had in the stock purchase agreement to Washburn. As a result and as appellants note in their brief, "Washburn stepped into the shoes of Corinthian as it relates to SCI.”
. Only SCI sought relief for unjust enrichment. Because SCI did not raise its unjust enrichment claim on appeal, we do not discuss this claim further.
. Not all jurisdictions apply this deferential standard of review when the equitable determination is made on summary judgment. For example, some courts have held that a de novo standard of review applies to equitable determinations made on summary judgment. See Kennedy Oil v. Lance Oil Gas Co., Inc.,
. In Cargill Inc. v. Ace Am. Ins. Co.,
. Rather than rely on Costello, appellants urge that we apply the analysis from the Restatement (Second) of Contracts § 152 to assess the rescission claim. See Restatement (Second) of Contracts § 152 (1981) (explaining that "[w]here a mistake of both parties at the time a contract was made as to a ba^ic assumption on which the contract was made has a material effect on the agreed exchange of performances, the contract is voidable by the adversely affected party unless he bears the risk of the mistake under the rule stated in § 154”). Outside the stock sale context, we have relied on the Restatement’s basic-assumption test in section 152 to examine claims for rescission based on mutual mistake. See Winter v. Skoglund,
