(1) whether the challenged provision is unconscionable under Commercial Real Estate as applied to installment payments, (2) if not, which installment payments generated a late fee, (3) whether the late fee provision applies to the [Note's final] balloon payment, and (4) if so, whether that application of the late fee is unconscionable.9
¶23 On remand, the district court applied the Commercial Real Estate test and concluded that the 10 percent late fee provision was conscionable, that the 10 percent late fee provision did not apply to the Note's balloon payment, and that, even if it did, its application to the final balloon payment would be unconscionable. It also concluded that the district court's pre-appeal instructions regarding the payment dates had not been appealed and would "remain the law applicable in this case." Finally, it requested the parties to submit accountings consistent with its order.
¶24 Both parties submitted proposed accountings, but their calculations differed drastically from each other. Under the Park Defendants' accounting, the Bradys still owed $ 785,977.01, and under the Bradys' accounting, the Bradys' had overpaid Mr. Park by $ 256,255.00-a discrepancy of $ 1,042,232.01.
¶25 The wide gap between each party's calculation was due, in part, to a disagreement regarding whether the 10 percent late fee had to be paid with each late installment *403payment or at the end with the final balloon payment. Mr. Park argued that it became due upon each default, so it had to be paid with the late installment payment to bring the Note current, thereby stopping the accrual of 20 percent default interest. The Bradys, in contrast, argued that late fees were not due until the final balloon payment. After considering these arguments, the district court agreed with the Bradys and held that only the late installment payment needed to be paid to bring the Note current.
¶26 The parties also disagreed over the dates of the installment payments. The Park Defendants' accountant incorporated Mr. Hoffman's original payment dates into his calculation, but the Bradys' accountant made his calculation using different dates.10 The Park Defendants urged the district court to adopt their proposed accounting because it was "consistent with the previous undisturbed findings in this case," whereas the accounting submitted by the Bradys' accountant contained "a number of errors inconsistent with the record." Although the district court considered the Park Defendants' arguments, it ultimately accepted the Bradys' proposed accounting and issued final judgment to the Bradys in the amount of $ 256,255.00. Additionally, the court declined to award attorney fees to either party, but awarded pre- and postjudgment interest at the rate of 10 percent per annum pursuant to Utah Code sections 15-1-1 and 15-1-4.
¶27 The court awarded the judgment amount joint and severally against the Park Defendants. The Park Defendants filed a motion pursuant to rule 60(b) of the Utah Rules of Civil Procedure to remove the joint and several designation from the Bank of Utah and Paul M. Halliday. The motion was brought on the ground that the Bank of Utah-as custodian of Mr. Park's IRA-and Mr. Halliday-as trustee of two trust deeds securing the Note-had been joined in the case only as defendants to the Bradys' claim for injunctive relief. According to the Park Defendants, the court could not now award monetary damages against the Bank of Utah and Mr. Halliday because the Bradys' never alleged any monetary damages against them in their complaint. The Bradys argued, however, that the joint and several designation was appropriate because the Note was held in Mr. Park's IRA account-of which the Bank of Utah is the custodian. They also argued that it was appropriate because the Bank of Utah, acting on behalf of the IRA, had used the pre-appeal judgment11 to foreclose on the Bradys' real property. The district court issued a two-sentence order denying the rule 60(b) motion.
¶28 The Park Defendants appeal the judgment and the district court's denial of the rule 60 motion. We have jurisdiction pursuant to Utah Code section 78A-3-102(3)(j).
Standards of Review
¶29 The first and second issues require us to consider the district court's interpretation of a contract. We review a district court's interpretation of a contract for correctness.12 But if a contract term is ambiguous, district courts should consider extrinsic evidence to resolve the ambiguity.13 If a district court makes a determination of the parties' intent after considering extrinsic evidence, this is a factual determination to which we grant deference.14 So if the court's decision hinges upon extrinsic evidence, it should be overturned only if clearly erroneous.15
*404¶30 Third, we consider whether the district court violated the mandate rule. We review a district court's holdings regarding the mandate rule for correctness.16
¶31 Fourth, we consider the district court's decision to award pre- and postjudgment interest. We review a district court's decision in this regard for correctness.17
¶32 Fifth, we consider the district court's decision to award no attorney fees. We review a district court's determination of which party is the prevailing party under an abuse of discretion standard.18 But legal questions that pertain to the attorney fees issue, such as the proper interpretation of the Note at issue here, are reviewed for correctness.19
¶33 Sixth, we consider the district court's rule 60(b) determination. We conduct this review under an abuse of discretion standard.20
¶34 Finally, we consider our jurisdiction over the Bank of Utah, as custodian of Mr. Park's IRA. The question of whether we have jurisdiction over an appeal is a question of law.21
Analysis
¶35 The parties raise seven issues on appeal. First, the Park Defendants argue that the district court erred in interpreting the Note as providing that the 10 percent late fee amounts need not be paid to bring the Note current. They argue that the court erred in making this interpretation because it violated the mandate rule. We disagree. They also argue that, even if it did not violate the mandate rule, the court's interpretation of the Note was incorrect. Although we agree with the district court that the Note is ambiguous on this point, we hold that the court erred in deciding this issue because it construed the ambiguity against the Park Defendants, as drafters, without first considering extrinsic evidence. Accordingly, we reverse the district court's decision on this point and remand for a new determination after the court considers relevant extrinsic evidence.
¶36 The Park Defendants also challenge the district court's interpretation of the Note's 10 percent late fee provision as it relates to the final balloon payment. We affirm the court's finding, because it was not clearly erroneous, that extrinsic evidence showed that the parties did not intend the 10 percent late fee provision to apply to the final balloon payment.
¶37 Next, the Park Defendants argue that the district court violated the mandate rule by accepting payment dates that differed from payment dates accepted by the pre-appeal district court. We agree. Accordingly, we reverse the court's payment date determination and remand for an accounting consistent with the pre-appeal payment dates.
¶38 Furthermore, the Park Defendants challenge the district court's determination regarding pre- and postjudgment interest and its rule 60(b) ruling. We affirm the court's rule 60(b) ruling, but reverse its pre- and postjudgment interest determination and remand for an award of interest at a more appropriate interest rate.
¶39 Additionally, both parties challenge the district court's attorney fees determination. Because our holdings regarding the other issues in this case may have upended the basis for the court's attorney fees decision, we remand for a new attorney fees determination.
¶40 Finally, the Bradys claim that we do not have jurisdiction over Mr. Park's IRA, because the Bank of Utah, as custodian for *405Mr. Park's IRA, failed to file a timely notice of appeal. We hold that we have jurisdiction over the IRA through its owner, even though we do not have jurisdiction over the Bank of Utah.
¶41 We discuss the merits of each issue in turn.
I. The District Court Did Not Violate the Mandate Rule by Determining that the Note Did Not Require the 10 Percent Late Fees to be Paid to Bring the Note Current, But Erred in Making This Determination By Construing an Ambiguity in the Note Against the Park Defendants Without First Considering Relevant Extrinsic Evidence
¶42 The district court determined that the Note did not require the Bradys to pay unpaid 10 percent late fee amounts to bring the Note current. The Park Defendants argue that the court erred in making this determination for two reasons. First, they assert that it violated the mandate rule-a subcategory of the law of the case doctrine. Second, they argue that the court's interpretation of the Note was incorrect. Although we hold that the district court was not precluded by the mandate rule from deciding this issue, we hold that the court erred in deciding this issue by construing the ambiguity in the Note against the Park Defendants, as drafters, without first considering relevant extrinsic evidence.
A. The district court did not violate the mandate rule when it determined that the 10 percent late fees were not required to be paid to bring the Note current
¶43 First, the Park Defendants argue that the district court violated the mandate rule when it determined that the Note did not require the 10 percent late fees to be paid to bring the Note current, thereby stopping the accrual of the 20 percent default interest. Because neither the pre-appeal district court nor the court of appeals had previously decided this issue, we hold that it never became the law of the case under the mandate rule, and so the district court on remand was free to decide the issue.
¶44 The "[l]aw of the case terminology has been applied to a number of distinct sets of problems, each with a separate analysis."22 For example, "[i]n the initial stages of litigation ... this rule has reference only to the parties to the case."23 So "[w]hile a case remains pending before the district court prior to any appeal , the parties are bound by the court's prior decision, but the court remains free to reconsider that decision."24
¶45 But after a "case has been appealed and remanded," the law of the case becomes binding upon the district court under what is commonly referred to as the mandate rule.25 The mandate rule "dictates that pronouncements of an appellate court on legal issues"26 and "prior decision[s] of a district court become[ ] mandatory after an appeal and remand."27 This branch of the law of the case doctrine "serves the dual purpose of protecting against the reargument of settled issues and of assuring adherence of lower courts to the decisions of higher courts."28
¶46 The mandate rule is especially important in a case, such as this, that involves parties locked in seemingly endless *406cycles of litigation.29 For this reason, we will enforce the mandate rule if the district court disturbed any of its pre-appeal factual findings or legal conclusions, or a legal determination of the court of appeals. But because neither the pre-appeal district court, nor the court of appeals, had previously determined this issue, the district court on remand was free to reach it.
¶47 Before the first appeal, the district court never reached the question of whether the 10 percent late fee must be paid to bring the Note current, because it ruled that the late fee was unconscionable and thus unenforceable. The court of appeals considered the district court's unconscionability determination, but because the court of appeals held that the district court had applied the wrong legal test, it remanded the case to the district court so that it could make a new unconscionability determination using the test we established in Commercial Real Estate Investment, L.C. v. Comcast of Utah II, Inc.30 Consequently, the court of appeals never discussed the effect the payment of the 10 percent late fee would have on the accrual of default interest.
¶48 The Park Defendants maintain, however, that at one point in the opinion the court of appeals ruled that the payment of the 10 percent late fee would be paid "together" with late installment payments. But when this comment is viewed in context of the opinion as a whole, it is clear that the court was not attempting to make a legal determination regarding the due date of the late fees or their effect on the accrual of default interest.
¶49 The court of appeals made the comment in considering the separate issue of whether the Note required the Bradys to pay off any of the already accrued default interest in order to bring the Note current, thereby stopping the accrual of additional default interest. During this discussion, the court stated that "payment of the accrued default interest was not required to bring the Note current," and so "the 20% default interest rate runs from the expiration of the five-day grace period until the payment was made, together with the 10% late fee (if the trial court determines on remand that the 10% late fee is enforceable)."31
¶50 The Park Defendants argue that the "together with the 10% late fee" language constituted a determination that the 10 percent late fee had to be paid to bring the Note current. But we disagree. It is unlikely that by making this comment the court of appeals intended to rule on this issue because the issue had not been presented and briefed by the parties.32
¶51 Because the district court ruled that the 10 percent late fee provision was unconscionable before the first appeal, it did not decide whether a late fee incurred under that provision had to be paid to bring the Note current. Consequently, there was no order for the parties to challenge and, as a result, the parties did not brief this issue for appeal. For this reason, it is unlikely that the court of appeals intended its passing statement-that any late fees would be paid "together" with a late installment payment-to be a binding legal determination that any incurred 10 percent late fees must be paid to bring the Note current.33 This inference is strengthened *407by the fact that the court of appeals did not include this phrase when summarizing the court's legal determinations in the opinion's conclusion section.34 Accordingly, we hold that the court of appeals did not make a legal determination regarding whether the 10 percent late fee must be paid to bring the Note current, so the district court did not violate the mandate rule when it decided this issue.
B. The district court correctly concluded that the Note is ambiguous regarding what is required to bring the note current under the 20 percent default interest provision, but it erred by failing to consider extrinsic evidence before construing the ambiguity against the Park Defendants
¶52 The Park Defendants also argue that even if the district court did not violate the mandate rule by determining this issue, it nevertheless erred by interpreting the Note incorrectly. The court determined that the Note was ambiguous regarding what was required to bring the Note current. Rather than attempting to resolve this ambiguity by considering extrinsic evidence, it decided the issue by construing the ambiguity against the Park Defendants as the drafters of the provision. As a result, it concluded that the Note did not require the 10 percent late fee to be paid to stop the accrual of interest at the 20 percent default rate. We agree that the Note is ambiguous, but we reverse the district court's decision and remand for further factual findings because the district court failed to adequately consider extrinsic evidence before construing the Note against the Park Defendants.
¶53 When we interpret a contract "we first look at the plain language [of the contract] to determine the parties' meaning and intent."35 "If the language within the four corners of the contract is unambiguous, the parties' intentions are determined from the plain meaning of the contractual language, and the contract may be interpreted as a matter of law."36 But where a contractual term or provision is ambiguous as to what the parties intended, the question becomes a question of fact to be determined by the fact-finder.37 So where parties to a contract dispute propose competing interpretations of a contractual term or provision, we must determine whether the contract as a whole unambiguously supports one interpretation over the other. If "uncertain meanings of terms, missing terms, or other facial deficiencies" prevent the court from determining which of the "proffered alternative interpretations" the parties intended when they entered into the contract, then the court deems the contractual provision at issue ambiguous, and the ambiguity must be resolved by considering extrinsic evidence of the parties' intent.38
¶54 In his dissent, Justice Lee argues that we have never clearly explained when a contractual term is sufficiently ambiguous to open the door to extrinsic evidence. But this argument brushes aside sixty years of our caselaw in which we have repeatedly set forth the following standard:
*408where there are two reasonable39 interpretations of a contractual provision, we look to extrinsic evidence.40 So a contractual term or provision is ambiguous if "it is capable of more than one reasonable interpretation because of uncertain meanings of terms, missing terms, or other facial deficiencies."41
¶55 Justice Lee argues, however, that we have never explained "what it means for competing parties both to offer a 'reasonable' interpretation of the contract provision in question."42 Although it is true that we have used the term "reasonable" repeatedly for decades without defining the term further-presumably under the assumption that it is a bedrock term whose meaning was obvious-we have provided a consistent explanation for what constitutes a reasonable interpretation sufficient to create an ambiguity. Under our caselaw a reasonable interpretation is an interpretation that cannot be ruled out, after considering the natural meaning of the words in the contract provision in context of the contract as a whole, as one the parties could have reasonably intended.43 In other words, if the court determines *409that either of the competing interpretations could reasonably have been what the parties intended when they entered into the contract, then the contract is ambiguous.44 Where we conclude that either of the contract interpretations could reasonably have been what the parties intended, we will not substitute our judgment for that of the parties by choosing what we believe to be the better of the two interpretations.45 *410¶56 So where a contractual term is genuinely ambiguous, "we seek to resolve the ambiguity by looking to extrinsic evidence of the parties' intent."46 A determination of the parties' intent based on extrinsic evidence is a factual determination that should be made by the fact-finder.47 In the rare case where the extrinsic evidence "does not reveal the intent of the parties,"48 a district court should then, and only then, "resolve the ambiguity against the drafter."49
¶57 The first step of this analysis-deciding whether the contractual term is ambiguous-is a legal determination that we review for correctness, but the district court's findings regarding the extrinsic evidence are factual determinations that deserve deference.50 Accordingly, if the district court's decision hinges upon extrinsic evidence, it should be overturned only if it was clearly erroneous.51
¶58 Although the district court in this case was correct in holding that the Note is ambiguous regarding what must be paid to bring the Note current, we hold that the court erred by deciding the issue by construing the ambiguity against the Park Defendants without first considering relevant extrinsic evidence.
1. The note's plain language
¶59 First, we address the district court's determination that the Note is ambiguous regarding what is required to bring the Note current under the 20 percent default interest provision. The Park Defendants argue that any potential ambiguity in the 20 percent default interest provision should be resolved in their favor when considered together with their proposed interpretation of a phrase within the Note's 10 percent late fee provision. We hold that the language of the 20 percent default interest provision is ambiguous even if we interpret the 10 percent late fee provision as the Park Defendants suggest.52
*411¶60 The 20 percent default interest provision states: "If payment is not made within 5 days of due date the entire balance shall bear interest at a rate of 20 percent until note is brought current." So under this provision interest accrues on "the entire balance" at 20 percent until the Note "is brought current." Although the Park Defendants assume that any and all outstanding debts owed under the Note must be paid to bring the Note current, this assumption is not expressly supported by anything in the Note. The phrase "brought current" is not defined elsewhere in the Note and is not used in connection with a payment type other than the monthly installment payment. So even though it is reasonable to interpret the phrase-as the Park Defendants suggest-to require that the Bradys pay all late installment payments and late fees in order to bring the Note current, we find that it is also reasonable to read the Note to allow the Bradys to bring it current by paying only late, or missing, installment payments.
¶61 The latter interpretation is suggested by the structure of the Note. The structure contemplates three categories of payments: (1) monthly installment payments, (2) a final balloon payment, and (3) a 10 percent late fee for every late installment payment. Under the terms of the Note, a monthly installment payment of $ 5,923.61 is due "on the [first] day of each and every month" for ten years. The "entire principal balance together with interest thereon" (final balloon payment) is due on October 31, 2006. And the 10 percent late fees are potentially due either immediately when incurred or together with the final balloon payment.
¶62 Importantly, of these three types of payments, it is only the monthly installment payment that is specifically tied to the 20 percent default interest provision. The Note specifies that the 20 percent default interest will begin accruing on "the entire balance"53 if the "[installment] payment is not made within 5 days of due date."54 So it is only the *412failure to timely pay installment payments-and not a failure to pay the other two types of payments contemplated in the Note-that triggers the 20 percent default interest. In this way, the Note specifically ties the installment payments to the 20 percent default interest provision, something it does not do for the other types of payments. Because the monthly installment payment is the only type of payment contemplated in the default interest provision, it is reasonable to conclude that the phrase "brought current" within the provision refers only to the payment of late installment payments.
¶63 In sum, the phrase "brought current" has two reasonable interpretations. The Note could, as the Park Defendants argue, require the payment of the missed installment payments as well as a payment of any 10 percent late fees that are currently due to bring the Note current. But it could just as reasonably require only the payment of the missed installment payments. Because the phrase "brought current" is not defined in the Note-and this omission leads to two contradictory but reasonable interpretations-we conclude that the Note is ambiguous.55
2. Extrinsic evidence
¶64 Because the 20 percent default interest provision is ambiguous, our well-established pattern of contract interpretation would ordinarily require us to consider the district court's factual findings regarding relevant extrinsic evidence.56 But that is not possible in this case because the district court failed to make the necessary factual findings. Rather than looking to the extrinsic evidence to resolve the ambiguity, the court instead skipped to construing the provision against the Park Defendants as the drafters. This was error.
¶65 By failing to consider extrinsic evidence before construing the ambiguous provision against the Park Defendants, the district court did what we expressly refused to do in Meadow Valley Contractors .57 In that case the appellant asked us to resolve an ambiguity in a construction contract against the appellee who drafted the contract. We noted that by suggesting this, the appellant was ignoring "a critical analytical step."58 We then explained the proper methodology a court should follow after concluding that the text of a contract is ambiguous: "when a trial court concludes that contractual language is ambiguous, the court will invite extrinsic evidence bearing on the intentions of the parties to the contract concerning the ambiguity. The court would then assess the merits of the extrinsic evidence and reach a conclusion about the intentions of the parties."59 We finished by stating that "[o ]nly if the court concludes that the extrinsic evidence does not reveal the intent of the parties and uncertainty remains will the court construe the ambiguity against the drafter."60 In this case, the district court failed to assess the merits of the extrinsic evidence before construing the ambiguity in the default interest provision against the Park Defendants as the drafters. For this reason, we reverse the district court's decision and remand for a determination that considers the relevant extrinsic evidence.
*413II. We Affirm the District Court's Determination Regarding the 10 Percent Late Fee's Application to the Balloon Payment
¶66 Next, we consider the Park Defendants' challenge of the district court's interpretation of the Note's 10 percent late fee provision as it relates to the final balloon payment. The district court concluded that, under the plain language of the Note, the 10 percent late fees did not apply to the final balloon payment. Additionally, the court held that extrinsic evidence, in the form of a memorandum of understanding drafted by the parties, supported this interpretation. And, alternatively, the court held that even if the 10 percent late fee provision did apply to the final balloon payment, it would be unconscionable and thus unenforceable. The Park Defendants challenge each of these determinations. We hold that the district court's interpretation of the language of the 10 percent late fee provision is reasonable. Therefore a determination that the Park Defendants' alternative interpretation is also reasonable would merely render the Note ambiguous. And because we find that the district court's determination regarding extrinsic evidence was not clearly erroneous, we affirm its determination on this basis.61 This holding moots the Park Defendants' unconscionability challenge, so we decline to address it. As we did with the district court's interpretation of the 20 percent default interest provision, we first examine the contract's plain language. And because the Park Defendants' alternative interpretation could render the contract ambiguous, we also consider the district court's findings regarding the extrinsic evidence.62
A. Plain meaning of the Note
¶67 We begin by interpreting the text of the 10 percent late fee provision. The district court concluded that the provision unambiguously did not apply the 10 percent late fee to the final payment. The court considered the Note's relevant text, which states that Dr. Park would be paid $ 675,000:
[T]ogether with interest from date at the rate of 10 per cent per annum on the unpaid principal, said principal and interest payable as follows:
$ 5,923.61 due in [sic] the 1st day of January 1997, and $ 5,923.61 on the 1st day of each and every month thereafter until October 31, 2006, at which time the entire principal balance together with interest thereon is paid in full.
Interest shall accrue from December 1, 1996.
The payment is based on a 30 year amortization.
Each payment shall be applied first to accrued interest and the balance to the reduction of principal. If a payment is not made within five (5) days of due date, a late fee of 10 per cent will be due. If payment is not made within 5 days of due date the entire balance shall bear interest at the rate of 20% until note is brought current.
The district court noted that this provision differentiates between the $ 5,923.61 installment payments made "every month" from the "entire principal balance" balloon payoff, which is due on October 31, 2006. The court also noted that this distinction carries through to the 10 percent late fee provision. For example, the 10 percent late fee provision applies only if "payment" is not made within the five-day grace period and nothing in the provision suggests that the 10 percent late fee also applies if the "entire principal *414balance" payoff is not timely made. Thus, according to the district court, the Note clearly contemplates two types of payments-the installment payments and the balloon payment-and the 10 percent late fee provision applies only to the installment payments.63 This interpretation is reasonable, especially when the entire Note is viewed in context.
¶68 That "payment" refers only to the Note's monthly installment payments is suggested by language in the Note's amortization provision. After specifying that an installment payment in the amount of $ 5,923.61 is due each month, the Note states that the "payment is based on a 30 year amortization." Amortization is defined as "[t]he act or result of gradually extinguishing a debt ... by contributing payments of principal each time a periodic interest payment is due."64 So when the Note states that the "payment is based on a 30 year amortization," it means that the $ 5,923.61 monthly installment payment amount was determined by calculating how much the Bradys would need to pay each month for a period of thirty years in order to pay off the Note's $ 675,000 principal while incurring interest at a 10 percent rate. Because no other type of payment contemplated in the Note could be "based on a 30 year amortization," it is reasonable to conclude that the term "payment" in the amortization provision refers to the monthly installment payment.
¶69 The meaning of the term "payment" in the amortization provision is consistent with its meaning throughout the rest of the Note. For example, the first sentence of the Note's next paragraph states that "[e]ach payment shall be applied first to accrued interest and the balance to the reduction of principal." Once again, the term "payment"-as it is used here-could only reasonably refer to the monthly installment payment, and not the other two types of payments contemplated by the Note. It couldn't reasonably refer to the 10 percent late fee payment, because that payment would necessarily be applied to amounts owed for late fees. And it couldn't reasonably refer to the final balloon payment, because the final balloon payment, by its very nature, must be in the amount of the total remaining balance (principal plus interest), so it would not matter in which order it is applied. So once again the only payment type the term "payment" could reasonably refer to in this provision is the monthly installment payment.
¶70 Because it is reasonable to conclude that "payment," as it is used throughout the Note, refers only to the monthly installment payment, it arguably maintains this meaning when it is used in the 10 percent late fee provision.65 It is reasonable, therefore, to conclude that the 10 percent late fee provision applies only to the monthly installment payments-and not to the final balloon payment.
¶71 The Park Defendants interpret the 10 percent late fee provision, however, as applying to the final balloon payment. They state that the term "payment," as it is used throughout the Note, plainly refers to all payments due under the Note, including the final payment on October 31, 2006. So according to them, the use of the term "payment" in the late fee provision should be read to include the balloon payment. But we need not address the merits of the Park Defendants' alternative interpretation, because even if we found it to be reasonable, it would merely render the 10 percent late fee provision ambiguous, thereby requiring us to consider the district court's factual determination regarding extrinsic evidence. And because we conclude that the court did not clearly err when it determined that the extrinsic *415evidence shows that the parties did not intend the 10 percent late fee to apply to the final balloon payment, we must affirm the district court's decision even if the Park Defendants' alternative interpretation is reasonable.
B. Extrinsic evidence
¶72 The district court's factual determination regarding the 10 percent late fee provision's application to the final payment was not clearly erroneous. When reviewing a factual determination under a clearly erroneous standard, an "appellate court ... does not consider and weigh the evidence de novo."66 Accordingly, "[t]he mere fact that on the same evidence the appellate court might have reached a different result does not justify it in setting the findings aside."67 Instead, "[i]t may regard a finding as clearly erroneous only if the finding is without adequate evidentiary support or induced by an erroneous view of the law."68 In this case, the district court considered the parties' handwritten memorandum of understanding before finding that the parties intended the 10 percent late fee provision to apply only to the monthly installment payments. This determination is adequately supported by relevant extrinsic evidence.
¶73 In the memorandum of understanding, the parties wrote that "the payment will be made via monthly installments due on [the] First of each month with 10% late fee after five days." The district court concluded that "nothing in that provision addressed the balloon payment." Rather, "the parties defined 'payment' as 'monthly installments' made 'each month' and further provided that the 10% late fee applied only if those 'monthly installments' were more than five days late." Under this definition, the 10 percent late fee would apply to every installment payment from January 1, 1997 to October 1, 2006, but not to the final balloon payment due on October 31, 2006. We cannot say the district court clearly erred in making this determination.
¶74 The Park Defendants argue, however, that the memorandum of understanding shows that the 10 percent late fee should apply to the final balloon payment, as well as the monthly installment payments, because it treats all payments the same. In support, they assert that the memorandum of understanding "does not contain any separate definition of the final 'balloon payment,' nor does it set forth a different due date for that payment." But this argument fails because, as the district court pointed out, the Note treats the monthly installment and the final balloon payment differently, and it discusses the 10 percent late fee only in connection with the monthly installment payment.
¶75 Most noticeably, the Note treats the payments differently by establishing a different due date for the two payment types: each monthly installment is due on the first day of each month, but the due date for the final balloon payment is specifically set for October 31, 2006.
¶76 And as we have already noted, the memorandum of understanding treats the final balloon payment differently from the monthly installment payment by specifically establishing the 10 percent late fee for "monthly installment[ ]" payments without any reference to the final balloon payment. The Park Defendants argue that the term "monthly installments" includes the final balloon payment. But even if we agree that the term could be interpreted in this way, their argument would still fail because they have not shown that the district court's conclusions are unsupported by the language of the memorandum of understanding.69 Accordingly, the Park Defendants have failed to show that the extrinsic evidence does not adequately support the district court's factual determination, so we cannot say the court's determination was clearly erroneous.
*416¶77 For this reason, we affirm the district court's determination that the 10 percent late fee provision does not apply to the final balloon payment. Because this determination renders a review of the district court's unconscionability determination unnecessary, we decline to address it.
III. The District Court Violated the Mandate Rule by Recalculating the Dates of the Bradys' Installment Payments
¶78 The Park Defendants argue that the district court violated the mandate rule when it accepted an accounting determination that used payment dates that differed from the payment dates established pre-appeal. As we stated earlier,70 under the mandate rule when a "case has been appealed and remanded,"71 "pronouncements of an appellate court on legal issues"72 and "prior decision[s] of a district court [that were not disturbed on appeal] become[ ] mandatory" upon the district court on remand.73 So in this case, the district court's recalculation of the payment dates would violate the mandate rule only if the payment dates had been decided by the pre-appeal district court and survived appellate review. We hold that they did.
¶79 The district court made two pre-appeal determinations related to the payment dates: a legal determination interpreting the meaning of the term "payment date" and a factual determination accepting the actual payment dates established by a neutral, third-party accountant.
¶80 The district court first made its legal determination in its September 3, 2009 decision following the bench trial. The court explained that "a payment should be credited on the date plaintiffs' check was actually received by Mr. Park." But the court also noted that a smaller collection of checks had been accumulated and deposited in the bank as a group. For these accumulated checks, the court explained that "there is no persuasive evidence of a tardy payment, unless the date on the face of the check is beyond the agreed due date."
¶81 At the court's direction, the parties stipulated to the appointment of Rick Hoffman to serve as a neutral, third-party accountant who would calculate the amount owing on the Note. Mr. Hoffman determined the date of each payment and applied the applicable interest rates to arrive at a final payment amount. He then submitted his expert damage calculation on August 5, 2010.
¶82 On February 2, 2011, the district court issued its findings of fact and conclusions of law, in which it reiterated its prior legal determination interpreting the meaning of the term "payment date." At paragraph eighteen, the court discussed the payments as a whole: "Payments made by Plaintiffs under the Notes occurred on the date Park actually received the payment, and not on the date Plaintiffs mailed the payment or wrote a check for the payment." And at paragraph twenty-one, the district court discussed the smaller group of accumulated checks: "Park accumulated a series of Plaintiffs' payment checks and subsequently presented the series as a group for payment at the bank. Under these circumstances, these payments are considered received by Park when they were sent by Plaintiffs." So the district court reaffirmed its previous legal determination of the meaning of the term "payment date."
¶83 In the same February 2, 2011 decision, the district court also made a factual determination regarding the actual dates of payment by accepting Mr. Hoffman's accounting: "[The sum due and owing under the Note] was determined in accordance with the Court's direction and the Parties' stipulation in selecting Mr. Rick Hoffman to perform this calculation."74 By expressly recognizing *417that Mr. Hoffman performed his calculation "in accordance with the [district] [c]ourt's direction," the district court made a factual determination that Mr. Hoffman's factual findings-including the payment dates-were correct.
¶84 Because the district court incorporated its legal and factual determinations regarding the payment dates into its final, pre-appeal order, those determinations became binding on the district court upon remand as long as the court of appeals did not overturn them. It did not.
¶85 The court of appeals did not have an opportunity to address the legal or factual determinations regarding the payment dates, because neither party appealed them. Although the Bradys now argue they did challenge the district court's "original accounting" during the first appeal, the record clearly shows that the only parts of the accounting they challenged were the district court's legal conclusions that the Note called for compound interest, that the accrued 20 percent default interest had to be paid to bring the Note current, and that the 20 percent default interest provision was conscionable.75 Thus the district court's legal and factual payment date determinations proceeded unchallenged to the court of appeals.
¶86 Yet the Bradys argue that the court of appeals overturned the district court's pre-appeal payment date determinations.76 They base this argument on language in the court of appeals' opinion in which it instructs the district court to determine "which installment payments generated a late fee." But this comment cannot be interpreted as the Bradys suggest, because the court of appeals is unlikely to have ruled on issues that were not raised and briefed,77 and the court failed to conduct the necessary "clearly erroneous" review of the pre-appeal district court's factual payment date determinations.78 Rather than reading the court of appeals' instruction to determine "which installment payments generated a late fee" as an implicit rejection of the pre-appeal district court's legal and factual payment date determinations, we read it as merely an instruction to determine which of the already established payment dates fell beyond the due date. Accordingly, we find that the pre-appeal district court's legal and factual findings regarding the payment dates were not disturbed by the court of appeals.
*418¶87 Consequently, the district court on remand was bound by the pre-appeal payment dates. In fact, the court even acknowledged this in its May 7, 2015 Memorandum Decision, when it stated that "[t]his [payment date] ruling was not challenged on appeal and thus this issue has been decided and will remain the law applicable in this case." But the court later contradicted this statement when it misinterpreted its pre-appeal legal determination and completely disregarded its factual one.79
¶88 In both its May 7, 2015 and October 29, 2015 memoranda decisions, the district court quoted language from its pre-appeal, September 3, 2009 decision, in which it stated that "there [was] no persuasive evidence of a tardy payment, unless the date on the face of the check is beyond the agreed due date." But the court apparently failed to realize that it had made this statement while referring to the payment dates for a smaller group of accumulated checks that had been deposited as a group, and not to the payment dates as a whole. This was error. The language in the pre-appeal, February 2, 2011 findings of fact and conclusions of law makes it clear that the majority of payments "occurred on the date Park actually received the payment, and not on the date Plaintiffs mailed the payment or wrote a check for the payment." By overlooking the context in which it stated that "the date on the face of the check" constitutes the payment date, the court incorrectly concluded that the accounting submitted by the Bradys best conformed to its pre-appeal ruling.80
¶89 The court also overlooked its pre-appeal factual determination regarding the payment dates. Despite the fact that it had recognized that Mr. Hoffman's accounting-including the payment dates-conformed to its directions before the appeal, on remand the court accepted an accounting that utilized different dates.81 This too was error.
¶90 Because the district court's pre-appeal legal and factual determinations regarding the payment dates became the law of the case, the court on remand was bound by them. For this reason, the court's decision to accept different payment dates violated the mandate rule.
IV. The District Court Erred When it Awarded Pre- and Postjudgment Interest to the Bradys at a 10 Percent Rate
¶91 The Park Defendants next argue that the district court erred when it awarded 10 percent pre- and postjudgment interest to the Bradys. We agree.
A. The district court erred when it awarded prejudgment interest at a 10 percent rate under Utah Code section 15-1-1
¶92 As part of its October 29, 2015 memorandum decision, the district court awarded prejudgment interest to the Bradys at a rate of 10 percent pursuant to Utah Code section 15-1-1. The Park Defendants challenged this in their motion to alter or amend the final judgment,82 but the district court denied the motion because it held that section 15-1-1 applies to any "chose in action"83 and the Bradys' claim was indisputably a chose in action. The Park Defendants now challenge this legal conclusion.
*419¶93 The Park Defendants cite our decision in USA Power, LLC v. PacifiCorp ,84 to argue that section 15-1-1 is limited to "only those contracts ... for the 'loan ... of any money [or] goods' or for the 'forbearance of any ... chose in action.' "
¶94 The Bradys argue, however, that the district court's prejudgment interest award was correct because the Note constituted a contract for a loan and, under USA Power , section 15-1-1 still applies to any "lawful contract" for a loan. But this argument fails because the judgment awarded to the Bradys was not for money owed under a loan contract-it was for money owed due to an overpayment of money owed under a loan contract. This distinction is significant, and consequently we hold that the district court erred by concluding that section 15-1-1 applied to the Bradys' judgment.
¶95 Before our decision in USA Power , we had suggested-in dicta or without analyzing "the potentially limiting 'loan or forbearance' language in the statute"-that section 15-1-1 applies "to all cases involving a contract."85 Consequently, before our decision in USA Power , many courts interpreted section 15-1-1 as setting "a default interest rate" for most contracts.86 And, more importantly for our present discussion, courts also routinely applied the default 10 percent interest rate to overpayments made in connection with contracts.87 Although USA Power clarified that section 15-1-1 applied only to loan contracts, we did not expressly address its application to overpayments made in connection with loan contracts. Today we further clarify that section 15-1-1 does not apply to overpayments when the overpayments were not contemplated in the underlying contract, even when the overpayments were made in connection with a contract for a loan or forbearance.
¶96 This interpretation is required under the plain language of section 15-1-1. Although section 15-1-1 contains two subsections that establish prejudgment interest rates for certain types of contracts, neither subsection applies to the judgment awarded in this case.
¶97 Subsection (1) states that "[t]he parties to a lawful contract may agree upon any rate of interest for the loan or forbearance of any money, goods, or chose in action that is the subject of their contract."88 In other words, section 15-1-1(1) allows courts to award prejudgment interest at a rate chosen by the parties if the parties had previously agreed that the interest rate would be applied to the amounts for which judgment is awarded.
¶98 The proper application of section 15-1-1(1) may be demonstrated through a hypothetical. Imagine a typical loan contract, in which a lender agrees to lend a specified amount of money to a borrower, and the borrower agrees to pay the money back with interest at a specified rate. If the borrower fails to repay the loan and the lender prevails *420in an action to collect on amounts owed under the loan contract, section 15-1-1(1) authorizes the court to award prejudgment interest at the rate specified in the contract because the parties had agreed to apply it to the amounts the borrower owed the lender. But if the situation is reversed, and a borrower prevails in an action to recover amounts it inadvertently overpaid to the lender, it cannot be said that the lender agreed to pay interest on that amount-unless the contract specifies that the interest rate would apply in the event of an overpayment. So if the parties did not previously agree that the interest rate would apply to amounts owed due to overpayments, the contract does not contain an "agreed upon" interest rate under section 15-1-1(1). Such is the case here.
¶99 The Bradys' judgment was not awarded for amounts owed under an express provision of the Note. The purpose of the judgment was to compensate the Bradys for loan overpayments. And although the Note specifies that the amounts Mr. Park lent to the Bradys would accrue interest at a 10 percent interest rate, the Note does not contemplate the possibility of overpayments, much less specify an interest rate for amounts owed to the Bradys in the event of an overpayment. For this reason, we conclude that the Bradys' overpayments were not amounts owed under the terms of a contract for a loan or forbearance, and so we hold that section 15-1-1(1) did not authorize the district court to award prejudgment interest at a rate of 10 percent.
¶100 The plain language of section 15-1-1(2) compels the same result. Section 15-1-1(2) provides that "[u]nless parties to a lawful contract specify a different rate of interest, the legal rate of interest for the loan or forbearance of any money, goods, or chose in action shall be 10% per anum." Thus section 15-1-1(2) allows courts to award prejudgment interest at a rate of 10 percent if the parties to a contract for a loan or forbearance did not previously agree upon another interest rate. Because the only difference between the two subsections is that section 15-1-1(1) allows parties to establish any interest rate, whereas section 15-1-1(2) establishes a standard interest rate of 10 percent in the event the parties did not establish a specific interest rate, we conclude that, like section 15-1-1(1), section 15-1-1(2) applies only to amounts owed under the express terms of a contract for a loan or forbearance.
¶101 Because the Bradys' overpayments were not amounts owed under the express terms of a contract for a loan or forbearance, neither of section 15-1-1 's subsections authorized the district court to award prejudgment interest at a 10 percent rate. Accordingly, we reverse the court's prejudgment interest award and remand for an award of prejudgment interest that is consistent with this opinion.89
B. The district court erred when it awarded postjudgment interest at a 10 percent rate under Utah Code section 15-1-4
¶102 We likewise reverse the district court's decision to award postjudgment interest at a rate of 10 percent. The district court made its postjudgment interest ruling pursuant to Utah Code section 15-1-4(2)(a). Section 15-1-4(2)(a) provides that "a judgment rendered on a lawful contract shall conform to the contract and shall bear the interest agreed upon by the parties." The district court cited this language and concluded that it applied to this case because "the statute asks whether there was an interest rate 'agreed upon by the parties,' not whether the terms of the contract contemplate the specific *421claim presented to the Court." We disagree with the court's interpretation.
¶103 A correct interpretation of section 15-1-4(2)(a) hinges on the meaning of the phrase "interest agreed upon by the parties." While the district court's interpretation focused on the words "agreed upon" before correctly noting that the parties had agreed upon an interest rate in the Note, its statutory analysis ended prematurely because it failed to consider the underlying debt obligation to which the parties agreed the interest rate would attach.
¶104 An interest rate-by its very nature-is derivative of some other agreed upon contractual obligation.90 In other words, before parties can agree upon an interest rate-which will be calculated as a percentage of the amount of an underlying debt or other obligation-the parties must reach an agreement regarding the underlying debt or obligation. With this in mind, it is clear that section 15-1-4(2)(a) only authorizes the court to apply an interest rate chosen by the parties if the parties agreed that the interest rate would apply to the contractual obligation that forms the basis for the judgment award. In other words, section 15-1-4(2)(a) does not authorize courts to rewrite a contract by taking an interest rate contractually linked to one obligation and applying it to amounts owed under a different, unrelated obligation. This is especially true when the unrelated obligation had not been contemplated by the parties at the time the contract was formed.
¶105 In this case, the parties agreed that the Bradys would be obligated to repay a loan in the amount of $ 675,000 to Mr. Park. They then agreed upon an interest rate-10 percent-that would attach to that obligation. Importantly, the parties did not contemplate the possibility of loan overpayments, and they did not agree upon an interest rate that would attach to amounts owed to the Bradys due to loan overpayments. The district court erred, therefore, when it changed the terms of the parties' agreement by applying a 10 percent interest rate to a judicially created obligation to refund the Bradys' overpayments. For this reason, we reverse the district court's postjudgment interest determination and remand for an entry of postjudgment interest at the federal postjudgment interest rate, plus 2 percent, pursuant to Utah Code section 15-1-4(3)(a).91
V. The District Court Did Not Abuse its Discretion When it Denied the Park Defendants' Rule 60(b) Motion
¶106 We now consider the Park Defendants' claim that the district court abused its discretion when it denied their rule 60(b) motion. Rule 60(b) of the Utah Rules of Civil Procedure authorizes a court to "relieve a party or its legal representative from a judgment" for a number of reasons listed in the rule.92 When considering challenges to a court's ruling on a rule 60(b) motion, we "grant broad discretion" where the motions "are equitable in nature, saturated with facts, and call upon judges to apply fundamental principles of fairness that do not easily lend themselves to appellate review."93 In this case we decline to disturb the district court's rule 60(b) ruling.
¶107 In their rule 60(b) motion, the Park Defendants asked the district court to amend its judgment so that the judgment's "joint and several" designation no longer applied to Bank of Utah, as custodian of the IRA, and Paul M. Halliday, as trustee.94 They argued *422that the joint and several designation was a mistake under rule 60(b)(1) ; that it was not equitable to give the judgment prospective effect under rule 60(b)(5) ; and, alternatively, that their requested relief was justified under rule 60(b)(6). The Park Defendants have made the same arguments on appeal. We affirm the district court on all counts.
¶108 Rule 60(b)(1) authorizes a court to relieve a party from a judgment if the judgment was the product of a "mistake, inadvertence, surprise, or excusable neglect." The Park Defendants argue that the joint and several designation was a mistake under rule 60(b)(1) because the Bradys never sought monetary damages against the Bank of Utah or Mr. Halliday in their complaint. While the Park Defendants are correct on this point, they do not consider the grounds on which the district court awarded judgment. The judgment in this case was awarded based upon the Bradys' overpayment of amounts owed under the Note. And these overpayments were made pursuant to the district court's pre-appeal judgment for breach of contract, for which all of the Park Defendants were named plaintiffs and which resulted in a judgment in the amount of $ 2 million to all of the Park Defendants. Using this judgment, the Bank of Utah, acting on behalf of the IRA, foreclosed on some of the Bradys' real property. With these facts in view, we hold that the inclusion of the Bank of Utah and Mr. Halliday in an award for reimbursement was not an abuse of the district court's discretion.
¶109 Similarly, the district court did not abuse its discretion by rejecting the Park Defendants' rule 60(b)(5) and (b)(6) arguments. Rule 60(b)(5) authorizes a court to relieve a party from a judgment if "it is no longer equitable that the judgment should have prospective application." The Park Defendants argue that relief should have been granted under rule 60(b)(5) because "no allegations or evidence were ever presented to support" an award of prospective relief. But this argument is merely a rewording of their argument under rule 60(b)(1), and it fails for the same reason-the Bradys made overpayments to all of the Park Defendants together, so an award for reimbursement against all of the Park Defendants was within the court's discretion.
¶110 Finally, rule 60(b)(6) authorizes a court to relieve a party from a judgment for "any other reason that justifies relief." The Park Defendants argue that rule 60(b)(6) should apply in the event its other arguments do not succeed. Because the Park Defendants do not express any additional reasons in support of this last argument, it fails for the same reasons as the Park Defendants' rule 60(b)(1) and (b)(5) arguments.
¶111 In sum, because the Park Defendants together were awarded a judgment against the Bradys in the district court's first judgment, the court did not abuse its discretion by granting a reimbursement award against all of the Park Defendants in its second judgment. Accordingly, we affirm the district court's rule 60(b) ruling.
VI. We Vacate the District Court's Decision to Award No Attorney Fees and Remand for a New Attorney Fees Award Determination
¶112 Next, we consider the district court's attorney fees determination. Both the Bradys and the Park Defendants argue that the district court erred when it declined to award attorney fees in their favor. Because our rulings on the other issues in this case may have upended the basis for the court's attorney fees decision, we decline to address the parties' arguments. Instead, we vacate the district court's previous decision and remand for a new attorney fees determination.
VII. We Have Jurisdiction to Consider All of the Claims Brought by the Park Defendants
¶113 Finally, the Bradys argue that we do not have jurisdiction over Mr. Park's IRA on appeal because the Bank of Utah, as custodian for the IRA, failed to file a timely notice of appeal pursuant to rules 3(d) and 4(a) of the Utah Rules of Appellate Procedure. Although we agree with the Bradys that the deficiencies in the notice of appeal deprive us of jurisdiction over the Bank of *423Utah, we find that our jurisdiction over the remaining Park Defendants necessarily includes jurisdiction over all of the Park Defendants' property, which in this case includes the IRA.
¶114 The omission of an IRA custodian95 does not deprive us of jurisdiction over a self-directed IRA when we already have jurisdiction over the IRA's owner or beneficiary. Unlike a trust or a business entity, a self-directed IRA is not a legal entity that is distinct from its owner.96 Rather, it is more akin to property such as a bank account.97 When a court has jurisdiction over the parties to a case, the court has jurisdiction to adjudicate the parties' interests in their property.98 Because assets held in a self-directed IRA are property of the IRA's owner, jurisdiction over the owner necessarily confers jurisdiction over the IRA and all of the assets held in the IRA. So Mr. Park and the Park Trust's notice of appeal was sufficient to grant us jurisdiction over them and all of their assets, including the IRA.99
¶115 Additionally, we note that a corollary of this rule is that when we have jurisdiction over an owner of an IRA-including his or her interest in the IRA-the owner necessarily has standing to bring or defend claims directly implicating his or her interest in the IRA. Accordingly, we have frequently adjudicated interests in an IRA where the owner of the IRA, but not the IRA or the IRA's custodian, was joined as a party.100
¶116 This approach is followed in other jurisdictions. For example, in FBO David Sweet IRA v. Taylor ,101 a federal district court in Alabama ruled that the owner of a self-directed IRA was a proper party-plaintiff in a case involving assets deposited in an IRA because "it is the owner of the Self-Directed IRA who manages, directs, and controls *424the investments."102 So the court concluded that "the owner or beneficiary of the IRA acts as a trustee for all intent and purposes" whereas the bank custodian "served as merely a holding company" of the owner's property.103
¶117 Similarly, in Deem v. Baron104 the federal district court of Utah held that an IRA's custodian bank was not the proper party to litigate issues related to IRA contracts. After acknowledging the logic of the FBO David Sweet IRA opinion, the court explained that because the custodian bank "ha[d] not been involved in the decision-making process, it lack[ed] the knowledge of the facts which would allow it to bring th[e] action [in the case]."105 In contrast, the court held that the owners of the IRA were the "true parties in interest" in the litigation because "they are the ones most knowledgeable of all of the facts and circumstances surrounding those contracts" and "they are also the ones for whose benefit all of the transactions were performed."106 Accordingly, the court concluded that the owners of the IRA had standing to prosecute the case. So both FBO David Sweet IRA and Deem illustrate that our treatment of the IRA in this case is consistent with the treatment given to IRAs in other jurisdictions.
¶118 In sum, jurisdiction over a party also confers jurisdiction over the party's property. This is true even when the property in question is an IRA. And if we have jurisdiction to adjudicate a party's interest in his or her IRA, that party necessarily has standing to bring or defend claims implicating his or her interest in the IRA. In this case, the Bradys do not challenge our jurisdiction over Mr. Park individually or as trustee of the Park Trust. Because the Park Trust owns the IRA, we also have jurisdiction over the IRA, and Mr. Park-as trustee of the Park Trust-has standing to defend the Trust's interest in the IRA on appeal. Accordingly, we hold that although we do not have jurisdiction over the Bank of Utah, as custodian of the IRA, we nevertheless have jurisdiction over the IRA and the Park Trust's interest in it.
Conclusion
¶119 Although the district court was not precluded by the mandate rule from determining that the Note does not require the Bradys to pay any incurred 10 percent late fee amounts to bring the Note current, we hold that the court erred in making this determination because it did so by construing an ambiguity in the Note against the Park Defendants, as drafters, without first considering extrinsic evidence. Accordingly, we remand for a new determination after the court considers relevant extrinsic evidence.
¶120 Additionally, we affirm the district court's determination, because it was not clearly erroneous, that extrinsic evidence showed that the parties did not intend the Note's 10 percent late fee to apply to the final payment.
¶121 Further, we reverse the district court's acceptance of payment dates that differed from the payment dates it accepted before the first appeal because this determination violated the mandate rule.
¶122 We also reverse the district court's award of pre- and postjudgment interest at a 10 percent rate to the Bradys because Utah Code sections 15-1-1 and 15-1-4 do not authorize an award of interest at that rate. Accordingly, upon remand if the court awards a judgment to the Bradys, it should apply the correct pre- and postjudgment interest rates.
¶123 Additionally, we affirm the district court's ruling on the rule 60(b) motion because it was not clearly erroneous. But we reverse the district court's attorney fees determination *425and remand for a new attorney fees determination.
¶124 Finally, we conclude that we have jurisdiction over the IRA, through the IRA's owner, even though we do not have jurisdiction over Bank of Utah, as the IRA's custodian. We accordingly remand to the district court for proceedings consistent with this opinion.
