Atop the Chicago Board of Trade Building in downtown Chicago stands Ceres, the Roman goddess of agriculture and grain. She faces north, but her reach extends at least as far west as Ten Sleep, Wyoming, to the family cattle ranch of defendant-appellee Richard Carter. In 2010, through a broker in Scottsbluff, Nebraska, Carter opened a commodities futures and options trading account with a Chicago-based financial *363institution. Carter intended to use the account to secure the prices his ranch-defendant-appellee Ten Sleep Cattle Company-would receive for its cattle using various financial instruments.1

At the same broker's behest, Carter opened another account in 2011 with plaintiff-appellant Straits Financial to speculate in other investment categories. After Carter and the broker split a tidy profit of $300,000, Carter instructed the broker to close out the account in March 2012. The broker did not follow those instructions. Instead, he continued speculating on U.S. Treasury Bond futures, losing approximately $2 million over the course of the next three months before his unauthorized trading was stopped. Straits Financial then liquidated Carter's livestock commodities holdings to satisfy most of that $2 million shortfall, and turned to the courts for the remaining deficiency. After a bench trial, Carter prevailed on most points and established his ranch's right to the seized funds and an award of attorney fees. However, the district court significantly reduced the amount of damages, finding that Carter had failed to mitigate his ranch's damages by not closely reading account statements and trading confirmations during his broker's trading spree.

Straits Financial and Perkins have appealed, and Carter and Ten Sleep have cross-appealed. We must decide three principal issues: whether the district court correctly interpreted and applied the contracts governing Ten Sleep's relationship with Straits Financial; whether the award of attorney fees was proper; and whether Ten Sleep's damages should have been reduced under Illinois law. We affirm the district court's judgment on the first two questions, but we reverse and remand in part for recalculation of Ten Sleep's damages.

I. Factual Background and Procedural History

A. The 33 Account and 35 Account

As our western colleagues know, "cattle ranching is a hazardous business." Wootten v. Wootten , 159 F.2d 567, 574 (10th Cir. 1947). Unexpected fluctuations in the price of cattle can wipe out a family-run cattle operation. Covering the expenses of feeding, trucking, and pasturing cattle-plus all the other costs of running a ranch-is a perennial challenge. Ten Sleep's annual gross revenues in 2010 and 2011 were between $24 and $26 million, but the profit margins even in good years were less than 5%. To protect his business, in March 2010, Carter opened a commodity futures and options trading account with a futures commission merchant, R.J. O'Brien (RJO for short). Carter intended to use this account to protect his profit by locking in the price Ten Sleep would receive for its cattle later in the year. He did so by using options and other risk-reducing investment positions. In other words, Carter initially sought to "hedge" cattle. See generally Merrill Lynch, Pierce, Fenner & Smith, Inc. v. Curran , 456 U.S. 353, 357-60, 102 S.Ct. 1825, 72 L.Ed.2d 182 (1982) (describing commodities trading and hedging).

Carter set up this hedging account through his broker, Jason Perkins, who at the time was affiliated with RJO. This account, which the parties refer to as the "33 Account" for the last two digits of the account number, was established by an account agreement with RJO. The RJO agreement included a personal guarantee that required Carter to assume any debts *364owed by Ten Sleep to RJO. Specifically, that guarantee pledged "full and prompt payment to RJO of all sums owed to RJO by Customer pursuant to the [foregoing] Account Agreement, whether such sums are now existing or are hereafter created." In a section titled "DEBIT BALANCES," the agreement also allowed RJO to use any account balances or deposits to offset losses and expenses, and empowered RJO to pursue Ten Sleep for any remaining deficiencies. RJO also reserved the right to assign the account to another registered futures commission merchant. The RJO agreement did not include a mandatory arbitration clause, though it required Ten Sleep to dispute transactions within one year of the transaction date either through an administrative proceeding at the Commodity Futures Trading Commission or through a lawsuit or arbitration in the Northern District of Illinois. The RJO agreement provided that Illinois law would govern. Through the RJO agreement, Ten Sleep consented to the jurisdiction of the state and federal courts and arbitration forums in the Northern District of Illinois.

The 33 Account existed solely to protect against losses in Ten Sleep's cattle business and was used in accordance with that purpose. After about a year, in April 2011 Perkins moved his brokerage from RJO to plaintiff-appellant Straits Financial, where he became an employee and the manager of a branch office. As part of the "bulk transfer process" of moving accounts from RJO to Straits Financial, all of Perkins's customers, including Ten Sleep, received a "negative consent letter." The letter advised them that their accounts would be transferred unless they objected. See 17 C.F.R. § 1.65(a)(2) (2011) (requiring notice and "a reasonable opportunity to object" to such transfers). By a separate assignment agreement with RJO, which Carter did not see, Straits Financial took control of the 33 Account and its associated personal guarantee. Ten Sleep did not sign any transfer agreement with Straits Financial, and Carter did not give any explicit personal guarantees directly to Straits Financial at any time.

A few months later, in May 2011, Perkins approached Carter with a new idea: opening a speculative trading account with Straits Financial where Perkins would have discretion to invest Carter's money without prior authorization. Perkins assured Carter that he would simply "nibble around the edges" using this freedom, and that there would be "no margin calls," i.e., no demands for Carter to put new capital into the account in light of Perkins's speculative trades. Dkt. 83 at 3 (Judge Zagel's findings of fact); see also ADM Investor Services, Inc. v. Ramsay , 558 F.Supp.2d 855, 857 n.3 (N.D. Ill. 2008) (explaining "margin call" in context of futures trading) (citation omitted). In this conversation, Perkins proposed that he and Carter share the profits equally, and Carter agreed.2

*365No written authorizations or contracts documented this agreement, aside from Carter's signature on Straits Financial's one-page Related Account Authorization form, on which Perkins indicated that the new account was merely for "Record Keeping Purposes." The authorization form attempted to incorporate by reference "existing account documentation including but not limited to agreements ... maintained and existing on file with Straits," and all existing "terms and conditions." The authorization form did not, however, specifically identify any of the documentation, terms, or conditions that would carry over to the new account. Within a few days, Perkins began trading in what the parties call the "35 Account."

B. "We Kinda Have a Problem"

One might guess what happened next. After sustaining some initial setbacks from trading various commodities futures contracts, in early 2012 Perkins turned his speculative attention to Treasury Bond futures, and accumulated several hundred thousand dollars in profits. By mid-March, the net profit from Perkins's Treasury Bond trading in the 35 Account reached $300,000. On March 16 Perkins called Carter to share the good news. Carter instructed Perkins to "send [the $300,000] to me," and "I will send you your half back," which Carter later did by mailing Perkins a $150,000 check. Carter then told his broker, "close it out, don't do anything more ... Shut it down and don't do anything more."3

But Perkins did more. On twenty different days between March 16 and June 4, Perkins executed trades in the 35 Account, wagering hundreds of thousands of dollars on Treasury Bond futures even though the two accounts were nominally for livestock hedging and "Record Keeping Purposes." By mid-June, and without Carter's actual knowledge of them, the losses in the 35 Account exceeded $2 million. Carter did not realize there was a problem in his Straits Financial accounts until he tried to cash out a sizable position in the 33 Account and received no response. Carter finally got Perkins on the phone around June 20. Perkins admitted: "we kinda have a problem ... they're holding your account money in your livestock account to clear this up," with "this" being the $2 million shortfall in the 35 Account for "record-keeping."

Besides the fact that broker Perkins did not tell him about the losses, the record discloses at least two other reasons why Carter did not realize there was a problem until June 20. The first had to do with Straits Financial's margin policies. Because the two related accounts were being cross-margined, Ten Sleep's deposits into the 33 Account masked the problems developing in the 35 Account.4 This meant that while Carter wired well over a million dollars into his hedging account at Straits Financial between March and June 2012 in response to Perkins's requests, Carter did *366not know that these cash infusions into the 33 Account actually served to stave off the closure of both accounts as Perkins's trades kept digging the 35 Account into a deeper hole. Nor did Carter realize that the statements being sent to him covered not just the expected activity in the 33 Account but also the unexpected problems in the 35 Account.

The second reason why Carter failed to realize what was happening in the 35 Account was bovine. Although Straits Financial mailed him statements every month and after every trade was made, between March and May Carter spent all of his waking hours in Manderson, Wyoming, 40 miles away from Ten Sleep, because it was calving season. Between May and June, Carter was busy driving his cattle 240 miles to pasture in Rawlins, Wyoming. During this period, Perkins used Carter's unavailability as a stalling tactic with his Chicago-based bosses at Straits Financial, claiming Carter "is supposed to be calling me back" about the margin calls and assuring his superiors, "Don't worry we will be fine. [Carter] is just moving some stuff around in the fields."

Once Perkins came clean to Carter about the losses, the two agreed to meet at Carter's lawyer's office in Casper, Wyoming to discuss the problem and the fact that Straits Financial had moved to offset the shortfall in the 35 Account by seizing and liquidating the 33 Account. At the meeting, Carter explained that he thought the 35 Account was "supposed to zero out" and that Straits Financial should send him "100 percent of the money that was in the 33 account." Perkins responded: "that will not happen and can't happen." After several hours of discussion, Perkins signed an affidavit in which he admitted that he conducted "account activity on numerous occasions without consulting" Carter. Dkt. 6-2 at 2.5 After returning home, Perkins retained counsel, resigned from Straits Financial, and moved his brokerage to yet another firm.

C. The Litigation

In late June 2012, the combined balance of Carter's accounts had finally gone negative. Straits Financial liquidated the positions worth $1,823,168.77 in the 33 Account and applied them to the $1,992,045.79 deficiency in the 35 Account. This left a debit balance of $168,877.02, which Straits Financial sought to recover from Ten Sleep and Carter by filing this case, originally in an Illinois state court. Carter removed the case to the Northern District of Illinois based on diversity of citizenship, answered the complaint, and filed a counterclaim against Straits and a third-party complaint against Perkins. Carter alleged that the seizure of his 33 Account funds by Straits Financial amounted to conversion; that Straits Financial and Perkins were unjustly enriched, breached fiduciary duties, committed commodities fraud, and violated the Illinois Consumer Fraud and Deceptive Business Practices Act (ICFA); and that Straits Financial negligently supervised Perkins. The case proceeded to a bench trial in September 2014.

Carter prevailed on most of the points disputed at trial. Judge Zagel found that Perkins had defrauded him, that Straits Financial was vicariously liable for that fraud and for an ICFA violation, and that Carter also had proven unjust enrichment and conversion. Quoting Grundstad v. Ritt , 166 F.3d 867, 870 (7th Cir. 1999), the judge rejected Straits Financial's argument that the RJO agreement and its associated personal guarantee applied to the losses in the *36735 Account. Because Straits Financial "failed to clearly and specifically communicate to Ten Sleep which agreements and contracts were being assigned," the attempted assignment was invalid, and Straits Financial could not enforce the personal guarantee. Because Ten Sleep had prevailed on its ICFA claim, and because that statute permits the court to award "reasonable attorney's fees and costs to the prevailing party," 815 Ill. Comp. Stat. Ann. 505/10a(c), the judge also ordered Straits Financial to pay Ten Sleep's attorney fees.

However, the court agreed with Straits Financial's argument that by neglecting its account statements, Ten Sleep had failed to mitigate its damages through the exercise of "reasonable diligence and ordinary care," an expectation the court found to be imposed by Illinois law. The court reduced Ten Sleep's damages recovery "by the proportion of responsibility" Carter bore by not noticing Perkins's fraud earlier. In addition, the court rejected Ten Sleep's request for punitive damages.

After further briefing, the district court determined that Carter should be held responsible for losses accrued in the 35 Account between June 11 and 20, because of his failure to read and act on "dozens of communications from Straits including 23 letters" and statements related to the account. This reduced Ten Sleep's recovery from $2,206,754.80 to $1,457,601.50, though the district court did grant prejudgment interest on the eventual damages award. See Dkts. 99, 111, 113. After still more briefing and reassignment of the case to Judge Shah, the court awarded attorney fees and costs, finding the attorneys' work on Ten Sleep's ICFA claim "inextricably intertwined" with the other claims presented. Straits Financial LLC v. Ten Sleep Cattle Co. , No. 12 CV 6110, 2017 WL 5900280, at *1 (N.D. Ill. May 2, 2017).

Both sides have appealed. In the end, we agree with Carter and Ten Sleep on all three of the disputed issues. We affirm all of the district court's conclusions regarding Straits Financial's liability and the fee award, but we reverse the portion of its judgment requiring mitigation of damages. We remand for recalculation of Ten Sleep's damages.

II. Analysis

A. Standard of Review

Coming on the heels of a seven-day bench trial, the arguments and issues in this appeal defy easy labels. In most cases it is enough to repeat the usual refrain: "We review the district court's findings of fact for clear error, and review its conclusions of law de novo." Frentz v. Brown , 876 F.3d 285, 293 (7th Cir. 2017), citing In re Rovell , 194 F.3d 867, 870 (7th Cir. 1999). That usual statement is not quite adequate in this case. Here we have one issue for which the standard of review is straightforward-the decision to grant attorney fees under the ICFA is reviewable only for an abuse of discretion. Krautsack v. Anderson , 223 Ill.2d 541, 308 Ill.Dec. 302, 861 N.E.2d 633, 643-44 (2006) ("Because section 10a(c) [of the ICFA] states that the court 'may' award attorney fees and costs, and the word 'may' ordinarily connotes discretion, attorney fee awards are left to the sound discretion of the trial court.") (citations omitted); see also Pickett v. Sheridan Health Care Center , 664 F.3d 632, 639 (7th Cir. 2011) ("We review the award of attorneys' fees for abuse of discretion" unless "the district court denies a fee award based on a legal principle") (citations omitted).

The other issues in these appeals are "mixed question[s] of fact and law," which is not necessarily a helpful label. See *368In re Text Messaging Antitrust Litig. , 630 F.3d 622, 625 (7th Cir. 2010) ; see also U.S. Bank Nat'l Ass'n ex rel. CWCapital Asset Management LLC v. Village at Lakeridge, LLC , --- U.S. ----, 138 S.Ct. 960, 967, 200 L.Ed.2d 218 (2018) ("Mixed questions are not all alike."). Our general task on such questions "is to determine the legal significance of a set of facts" found by the district court, which entails significant deference to the district court's conclusions when those conclusions are confined to the specific context of the case presented. Text Messaging Antitrust Litig. , 630 F.3d at 625 (distinguishing the "application of a legal standard to a unique, non-recurring set of particular facts").

For the most part, that is the approach we take here, analyzing the district court's conclusions of mixed questions for clear error. See Trovare Capital Group, LLC v. Simkins Industries, Inc. , 794 F.3d 772, 778 (7th Cir. 2015) ("We review mixed questions of fact and law (that do not involve constitutional rights) for clear error."), citing Levenstein v. Salafsky , 414 F.3d 767, 773 (7th Cir. 2005). But that deference ends when the district court ventures beyond "case-specific factual issues" and reaches broader legal conclusions applicable to a whole class of future cases. Village at Lakeridge , 138 S.Ct. at 967. In such situations the Supreme Court reminds us that it is an appellate function to "expound on the law, particularly by amplifying or elaborating on a broad legal standard" and to develop "auxiliary legal principles of use in other cases." Id . We therefore apply a clear-error standard of review in this case, taking care not to defer to the district court's judgment where it effectively announced new legal rules that would govern future cases.

B. Issues Presented

Straits Financial appeals the district court's findings on liability, but it does not challenge the district court's most basic findings: that Perkins committed fraud, for which Straits Financial is vicariously liable as his employer.6 Instead, Straits Financial argues that the district court erred by not ruling in its favor on several contract-based defenses that in its view should establish its right to liquidate the 33 Account and to recover the debit balance from Ten Sleep, as well as negate its liability for conversion and unjust enrichment. In this vein, Straits Financial first argues that the original RJO agreement and personal guarantee for the 33 Account should be extended to cover the losses in the 35 Account. If those terms, conditions, and guarantees apply through any one of several theories, then Carter and Ten Sleep are legally responsible for the 35 Account losses, and Straits Financial acted appropriately in pursuing them for those losses. We treat this as a mixed question of fact and law that involves interpreting the legal significance of a unique series of transfers, notices, agreements, and events that established Ten Sleep's relationship with Straits Financial.

Second, Straits Financial argues that the ICFA attorney fee award should be reduced. Its theory is that the work performed for Ten Sleep's ICFA claim was separable from attorney work on its other statutory and common-law claims. The district court's judgment on this question is reviewed for an abuse of discretion, as explained above.

Both Straits Financial and Ten Sleep (via a cross-appeal) challenge the district court's decision on mitigation of damages.

*369Straits Financial challenges the district court's selection of June 11 as the date from which Carter's damages should have been mitigated under Illinois law, arguing that the proper date should be April 5. Ten Sleep contends that no mitigation was required and that the district court erred by applying comparative negligence principles in a fraud case. As an application of a legal standard to a particular set of facts, this too is a mixed question of fact and law, but it has legal repercussions well beyond the facts of this particular case.

These are all issues of Illinois state law. We apply the relevant decisions of the Illinois Supreme Court, and if a question of law has not yet been decided by that court, we are to make a "prediction of how the Supreme Court of Illinois would rule" on it, using decisions of the state's intermediate appellate courts for guidance as necessary. Community Bank of Trenton v. Schnuck Markets, Inc. , 887 F.3d 803, 811-12 (7th Cir. 2018), quoting Taco Bell Corp. v. Continental Cas. Co. , 388 F.3d 1069, 1077 (7th Cir. 2004).

C. The Rules Governing the 35 Account

Straits Financial contends that the terms, conditions, and guarantees that constitute the 33 Account's original RJO agreement apply to both the 33 Account and new 35 Account at Straits. It points out that the RJO agreement specifically envisioned the possibility that the 33 Account could be moved to another financial institution, that the assignment of the agreement from RJO to Straits Financial is valid under Illinois law, and that Carter has admitted that Straits Financial sent the negative consent letter called for in federal regulations. See 17 C.F.R. § 1.65(a)(2) (requirements for "bulk transfers" of commodity accounts). Straits Financial argues further that the 33 Account's "terms and conditions" are the only ones that it and Ten Sleep could have adopted by reference through the boilerplate language in the Related Account Authorization form. Thus, Straits Financial concludes, the district court was wrong when it reasoned that the authorization form was "so opaque as to be unenforceable" against Ten Sleep. To what other terms and conditions could Carter have been assenting?

On the surface this seems like a strong argument. Illinois courts will enforce an assignment even if the "party whose obligations were assigned" did not receive notice of the transaction, absent exceptions not relevant here. See Grunloh v. Effingham Equity, Inc. , 174 Ill.App.3d 508, 124 Ill.Dec. 140, 528 N.E.2d 1031, 1039 (1988). Incorporation by reference is also permitted. See Wright v. Mr. Quick, Inc. , 109 Ill.2d 236, 93 Ill.Dec. 375, 486 N.E.2d 908, 910 (1985), citing Provident Federal Savings & Loan Ass'n v. Realty Centre, Ltd. , 97 Ill.2d 187, 73 Ill.Dec. 389, 454 N.E.2d 249, 251 (1983). To be enforceable, an Illinois contract need be only "sufficiently definite and certain" that a court may "ascertain what the parties have agreed to do," Reese v. Forsythe Mergers Group, Inc. , 288 Ill.App.3d 972, 224 Ill.Dec. 647, 682 N.E.2d 208, 214 (1997), quoting Academy Chicago Publishers v. Cheever , 144 Ill.2d 24, 161 Ill.Dec. 335, 578 N.E.2d 981, 983 (1991), which in this case was simple: open the 35 Account under the same standard rules, terms, and conditions as the 33 Account. We agree with Straits Financial to the extent that there must have been some rules that governed the 35 Account, and the authorization form shows an intent to make the RJO agreement's standard account formation terms like the forum selection clause and the electronic signature provisions apply to both accounts.

*370Straits Financial's argument runs aground, however, on a different point highlighted by the district court: how Illinois courts interpret guarantees. To have allowed Straits Financial to confiscate the property in the 33 Account, one of two theories must be correct. Either Carter's personal guarantee of "all sums owed to RJO ... now existing or ... hereafter created" under the 33 Account agreement must also have applied to guarantee losses in the 35 Account, or the RJO agreement's short section on debit balances and offsets, which briefly refers to a "Customer's obligations," must have served that same promissory function for the 35 Account.7

Yet guarantees are construed strictly in Illinois, meaning that "the scope of a guarantor's liability extends no further than that which the guarantor has agreed to accept." SouthernWine & Spirits of Illinois, Inc. v. Steiner , 380 Ill.Dec. 523, 8 N.E.3d 1065, 1069 (Ill. App. 2014), citing Riley Acquisitions, Inc. v. Drexler , 408 Ill.App.3d 397, 349 Ill.Dec. 461, 946 N.E.2d 957, 965-66 (2011). "A guarantor has acquired status as a favorite of the law, and when construing liability the court accords the guarantor the benefit of any doubts that may arise from the language of the contract." Southern Wine & Spirits of Illinois , 380 Ill.Dec. 523, 8 N.E.3d at 1069, citing Schiff v. Continental Nat'l Bank & Trust Co. of Chicago , 255 Ill. App. 333, 340 (1930). In addition, even where a guarantee's terms may apply after an assignment, a guarantor is discharged from liability if there is "a material change in the business dealings" between the parties "and some increase in the risk undertaken by the guarantor." See Southern Wine & Spirits of Illinois , 380 Ill.Dec. 523, 8 N.E.3d at 1070, citing Harris Trust & Savings Bank v. Stephans , 97 Ill.App.3d 683, 52 Ill.Dec. 927, 422 N.E.2d 1136, 1139 (1981) ; see also Grundstad v. Ritt , 166 F.3d 867, 870 (7th Cir. 1999). In the words of the district court, "Illinois courts look to 'whether there has been a material change in risk to the guarantor.' " Dkt. 83 at 9, quoting Grundstad , 166 F.3d at 870.

There certainly was a material change in business dealings and Ten Sleep's risks here. What began as a non-discretionary trading relationship designed to secure livestock price certainty for Ten Sleep turned into unauthorized and unrestrained speculation on Treasury Bond futures at the sole discretion of Straits Financial's employee, who defrauded Ten *371Sleep. The 35 Account was neither the same kind of business relationship nor, once the unauthorized trading began, did it present the same risks to Ten Sleep and Carter as the 33 Account. It was also not set up through clear and unambiguous contracts that would indicate Carter and Ten Sleep's willingness to be held responsible for Perkins's fraud (assuming such terms would even be enforced). Holding either Carter or Ten Sleep liable for those losses would stretch the boilerplate of the personal guarantee and the RJO agreement much further than Illinois law on guarantees permits. As Illinois courts have repeatedly said: "A guarantor's liability is not to be varied or extended beyond the terms of the guaranty." Roels v. Drew Industries, Inc. , 240 Ill.App.3d 578, 181 Ill.Dec. 338, 608 N.E.2d 411, 415 (1992) (citations omitted).

Straits Financial also argues that by not immediately objecting to the unauthorized trades Perkins made, Ten Sleep ratified those trades and must be held financially responsible for them. This is an offshoot of Straits Financial's argument that the RJO agreement applies, since paragraph 11 of the RJO agreement provided:

Unless a managed (discretionary) account has been arranged through the execution of a written trading authorization, each order should be communicated to RJO by the Customer or Customer's duly authorized broker. Instructions should include, but may not necessarily be limited to, the commodity involved, quantity, price, and delivery month. Any trade not specifically authorized by Customer must be immediately reported by Customer directly to RJO's Compliance Department. Customer will be financially responsible for all trades not so reported and for any losses arising by virtue of a course of dealing involving his grant of de facto control over the account to his broker.

Dkt. 153-1 at 14 (emphasis added). The RJO agreement provided further that a customer's failure to respond immediately would be considered a ratification of all account activity.8

Straits Financial's ratification argument fails under Illinois law for several reasons. First, deeming Carter's silence during the April-June period as consent to fraud would amount to yet another way of applying the 33 Account's personal guarantee to relieve Straits Financial and Perkins of liability for proven fraud.

Second, though Illinois permits "particular definitions" of contract terms to supersede the "generally accepted meaning" of the words used, see Continental Casualty Co. v. Donald T. Bertucci, Ltd. , 399 Ill.App.3d 775, 339 Ill.Dec. 358, 926 N.E.2d 833, 839 (2010), citing Sims v. Allstate Ins. Co. , 365 Ill.App.3d 997, 303 Ill.Dec. 514, 851 N.E.2d 701, 704 (2006), regardless of the particular definition of "ratification" used here, Illinois law allows contracting parties relief from fraudulent transactions as long as the fraud victim disavows the transaction "promptly after learning of the fraud." Freedberg v. Ohio Nat'l Ins. Co. , 363 Ill.Dec. 880, 975 N.E.2d 1189, 1197 (Ill. App. 2012) ("One seeking to rescind a transaction on the ground of fraud or misrepresentation must elect to do so promptly after learning of the fraud *372or misrepresentation, must announce his purpose and must adhere to it."), quoting Mollihan v. Stephany , 35 Ill.App.3d 101, 340 N.E.2d 627, 629 (1975) ; Kanter v. Ksander , 344 Ill. 408, 176 N.E. 289, 291 (1931) (same).

Immediately upon learning of this fraud, Carter maintained that the 35 Account was "supposed to zero out" on March 16 and that Straits Financial had to send him "100 percent of the money that was in the 33 account" when it was seized. Dkt. 146 at 637; see also Dkt. 6 at 13 (alleging conversion and demanding "immediate possession of the assets" taken). Carter had the right to seek this refund since "a party may exercise a right to rescind for fraud as to part of the contract" when valid business dealings can be severed from fraudulent activity. See Olson v. Eulette , 332 Ill.App. 178, 74 N.E.2d 609, 613 (1947) ; see also Keeshin v. Levin , 31 Ill.App.3d 790, 334 N.E.2d 898, 906 (1975). Here, Perkins's fraudulent activity after March 16 in the 35 Account is easily divisible from the legitimate accounts and trades authorized by Ten Sleep.

Finally, Illinois courts have rejected strict formalism when asked to excuse fraud. They are loath to reach "a result ... contrary to the established principle that a party committing fraud should be precluded from benefiting therefrom." Shanahan v. Schindler , 63 Ill.App.3d 82, 20 Ill.Dec. 239, 379 N.E.2d 1307, 1316 (1978), citing Bell v. Felt , 102 Ill. App. 218 (1902). So are we.

Under basic contract principles, Carter did not have an obligation to repudiate Perkins's trades until he had actual knowledge of them. See Restatement (Third) of Agency § 4.06 (2006) ("A person is not bound by a ratification made without knowledge of material facts"); see also Clews v. Jamieson , 182 U.S. 461, 483, 21 S.Ct. 845, 45 L.Ed. 1183 (1901) (noting the "well known" principle that a principal's ratification comes "within a reasonable time after the fact has come to his knowledge"); Eastern Trading Co. v. Refco, Inc. , 229 F.3d 617, 625 (7th Cir. 2000) (ratification occurs "by failing to repudiate [trades] upon discovery of them"); Stathis v. Geldermann, Inc. , 295 Ill.App.3d 844, 229 Ill.Dec. 809, 692 N.E.2d 798, 808 (1998) ("full knowledge of the act" needed), citing Peskin v. Deutsch , 134 Ill.App.3d 48, 89 Ill.Dec. 28, 479 N.E.2d 1034, 1039 (1985). Carter objected immediately upon discovering the fraud-he did not acquiesce to it. The RJO agreement does not change that conclusion.9

Also, Straits Financial's legal theory relies too heavily on a suggestion we made in a footnote in Anspacher & Associates, Inc. v. Henderson , 854 F.2d 941 (7th Cir. 1988). That opinion's footnote 2 hypothesized that "the terms of a signed customer agreement"

*373requiring prompt action by the customer to dispute transactions "could ... bar a commodities customer from recovering damages for his broker's fraud" under Illinois law. Id. at 947 n.2. For this possibility under Illinois law, though, Anspacher cited an Arizona case where a customer noticed and was irritated by (but did not formally object in writing to) unauthorized transactions occurring repeatedly over a period of several years. Id. , citing Shapiro v. Bache & Co., Inc. , 116 Ariz. 325, 569 P.2d 267, 270-71 (Ariz. App. 1977). Indeed, Shapiro reads like a case about an investor whose equivocal complaints about unauthorized transactions bordered on bad faith. As the Shapiro court explained, despite these purportedly unauthorized transactions:

Shapiro continued to execute transactions through his registered representatives, and to accept repeated notifications of the transactions in question and to pay margin calls on demand, all of which conduct continued for more than three years from the time of the first unauthorized transaction.

569 P.2d at 271 (emphasis added).

Nothing remotely like the facts in Shapiro happened here. Unlike the customer in Anspacher itself, Carter was not "waiting to see the results of those [unauthorized] trades" before expressing his concern. 854 F.2d at 942. Carter did not actually know about these trades until it was too late. When he found out, he immediately set up a meeting with Perkins. Finding Carter or Ten Sleep responsible for losses resulting from Perkins's proven fraud would in essence apply a guarantee or ratification that was never given. We affirm the district court's rejection of Straits Financial's defenses based on the RJO agreement.10

D. The ICFA Attorney Fee Award

We also agree with the district court, Ten Sleep, and Carter regarding the attorney fee award under the Illinois Consumer Fraud and Deceptive Business Practices Act (ICFA or Act). The ICFA permits trial courts to award fees to the prevailing party as a matter of discretion. 815 Ill. Comp. Stat. Ann. 505/10a(c) ; Ciampi v. Ogden Chrysler Plymouth, Inc. , 262 Ill.App.3d 94, 199 Ill.Dec. 609, 634 N.E.2d 448, 462-63 (1994). Illinois courts have interpreted this fee provision to allow fee awards for work on an ICFA claim and "for work on non-Act claims when the Act claim is so inextricably intertwined with the non-Act claims that it cannot be distinguished." Dubey v. Public Storage, Inc. , 395 Ill.App.3d 342, 335 Ill.Dec. 181, 918 N.E.2d 265, 283 (2009), citing Ardt v. State , 292 Ill.App.3d 1059, 227 Ill.Dec. 203, 687 N.E.2d 126, 131-32 (1997) (discussing case that "arose from a common core of facts"). Dubey also explained what Illinois courts mean by inextricably intertwined: "Here, we find that the conversion and breach of contract claims were [1] based on the same evidence and [2] the time spent on each issue could not be distinguished." Id. , citing Ciampi , 199 Ill.Dec. 609, 634 N.E.2d at 463. But it is not the case that "all counts in a consumer action tried together are compensable"-the party *374seeking fees must do more than show that "some of the evidence was the same." Schorsch v. Fireside Chrysler-Plymouth, Mazda, Inc. , 286 Ill.App.3d 1028, 222 Ill.Dec. 442, 677 N.E.2d 976, 979 (1997).

The district court did not abuse its discretion in awarding Ten Sleep fees for "the work reasonably performed on all of Ten Sleep's claims and defenses." Straits Financial LLC v. Ten Sleep Cattle Co. , No. 12 CV 6110, 2017 WL 5900280, at *2 (N.D. Ill. May 2, 2017). Among other elements, ICFA plaintiffs must prove a "deceptive act or practice by the defendant," must prove that the defendant intended for the plaintiff to rely on that deception, and must also prove that the deception proximately caused the plaintiff's damages. De Bouse v. Bayer , 235 Ill.2d 544, 337 Ill.Dec. 186, 922 N.E.2d 309, 313 (2009). This need to prove deception, intent, causation, and damages, and to defend these theories from legal counter-attack, meant that Ten Sleep had to uncover and present volumes of facts and arguments about Perkins's unauthorized trading and the relationships among Carter, Perkins, and Straits Financial. The details of the account formation, the unauthorized trading, and its consequences formed the common core of all theories in this case. As Judge Shah correctly observed: "Facts tending to prove fraudulent or deceptive activity were woven throughout this case and the work done to develop those facts and theories cannot be neatly separated by claim." Straits Financial , 2017 WL 5900280, at *2.11

E. Mitigation of Damages on the Fraud Claims

1. The Parties' Arguments

In their cross-appeal, Carter and Ten Sleep ask us to overturn the district court's judgment that they failed to mitigate their damages by "neglecting communications ... and never inquiring about suspicious circumstances," including the fact that Carter "did not know what document ... govern[ed] his relationship with Straits." Dkt. 83 at 10. The district court found that Carter should have discovered and put a stop to Perkins's fraud before June 20, 2012 by reading the mailed trading confirmations and asking about the status of the 35 Account. Judge Zagel found this amounted to a failure to exercise reasonable diligence and ordinary care under general principles of Illinois contract law. Id. , citing Ner Tamid Congregation of North Town v. Krivoruchko , 638 F.Supp.2d 913, 919-20 (N.D. Ill. 2009) ; see also Nancy's Home of the Stuffed Pizza, Inc. v. Cirrincione , 144 Ill.App.3d 934, 98 Ill.Dec. 673, 494 N.E.2d 795, 800 (1986) (in general, a "party being damaged cannot stand idly by and allow the injury to continue and increase without making reasonable efforts to avoid further loss"), citing Jensen v. Chicago & Western Indiana R.R. Co. , 94 Ill.App.3d 915, 50 Ill.Dec. 470, 419 N.E.2d 578, 591 (1981).

Accordingly, the district court decided to reduce Ten Sleep's damages to those incurred as of the June 11, 2012 trading day, an "earlier date" by which Perkins's unauthorized trading "could and should have been discovered." This resulted in a $749,153.30 reduction in Ten Sleep's damages, from approximately $2.21 million to around $1.46 million. Ten Sleep contests this conclusion and the resulting reduction in damages, arguing that the district court should not have applied duties and principles for ordinary contract or comparative negligence cases to reduce the recovery of a victim of intentional fraud. It argues *375further that no mitigation was possible until Carter learned the real facts of the fraud on June 20, at which point he took action immediately. For its part, Straits Financial asks us to affirm the district court's legal analysis, but to choose a much earlier starting date for the duty of mitigation: April 5, which would cut damages sharply.

Judge Zagel decided in essence that inquiry notice-in the form of trading confirmations and statements piling up in Carter's mailbox during calving season-was enough to treat Carter as if he were actually aware of the fraudulent activity in Ten Sleep's account, and was also enough to hold him responsible for Perkins's later unauthorized trades. The judge then selected a date by which Carter should have had that awareness, June 11, and reduced Ten Sleep's damages to the amount it should receive if Carter had intervened then.

2. Analysis

The Solomonic character of the judge's approach to the issue is readily apparent. We find, however, that the compromise was based on a faulty legal premise. Fraud victims are not responsible for their agent's fraud before they even learn of any unauthorized activity. Illinois courts have not adopted Straits Financial's or the district court's position on this issue. Under Illinois law, the injured party must have actual knowledge of the problem before it must act to mitigate its damages. See Continental Concrete Pipe Corp. v. Century Road Builders, Inc. , 195 Ill.App.3d 1, 142 Ill.Dec. 291, 552 N.E.2d 1032, 1042 (1990). Though Continental Concrete Pipe was a defective product case, its reasoning provides significant guidance here.

In Continental Concrete Pipe , according to the project specifications and unless it received contrary instructions, a construction company should have tested the sewer pipe it was laying after installing the first 1,200 feet of pipe. On the instructions of the local village engineer, though, the construction company delayed the pipe test until 1,800 feet had been completed. At that point, a test showed the pipe to be defective. Even though the construction company had laid an additional 600 feet of pipe before performing the required test, the court held it could still recover the full damages it suffered from the supplier's defective pipe. This was because, under Illinois law, "the duty to mitigate damages does not arise until the party upon whom the duty is impressed is aware of facts which make the duty to mitigate necessary." Id. (citation, quotation marks and brackets omitted). Because the construction company "did not become aware of any facts which made any duty to mitigate necessary" until it performed the belated test, no duty to mitigate arose before that time. Id.

We have reached the same conclusion in another case of fraud. The duty to mitigate damages does not arise until the injured party has actual knowledge of the injury. In other words, fraud victims are expected to take reasonable action once they are made aware of the real situation. But fraud victims will not lose the benefit of later remedies simply because better precautions on their part might have avoided the fraud or ended it sooner, which is often the case, especially with a court's benefit of hindsight. In a case about a loan from a pension fund and the fund's imprudent trustees, we said:

Had the trustees [simply] done what any investor should have done, there would have been no loss here....

But such investigations and other devices are distinctly second-best solutions to legal and practical problems, and we *376will not establish a legal rule under which investors must resort to the costly self-help approach of investigation on pain of losing the protection of the principal legal safeguard, the rule against fraud.

This is just another way to state the common law rule that contributory negligence is not a defense to an intentional or reckless tort. Prosser & Keeton, The Law of Torts 462 (5th ed. 1984); Restatement (Second) of Torts §§ 481, 482 (1965). The best solution is for people not to harm others intentionally, not for potential victims to take elaborate precautions against such depredations.

Teamsters Local 282 Pension Trust Fund v. Angelos , 762 F.2d 522, 527-28 (7th Cir. 1985). We did not base this rule on how elaborate the suggested precaution would be. Instead, we summarized the relevant inquiry in two parts:

The first question for the legal system is whether to create a duty to disclose information truthfully. Such a duty, if created, rests on the proposition that the information ought to come out, and that people ought not be left to their own investigative talents. Once the duty to disclose exists, and lying or nondisclosure is condemned as an intentional tort, it no longer matters whether the buyer conducts an investigation well or at all.

Id. at 528 ; see also Astor Chauffeured Limousine Co. v. Runnfeldt Inv. Corp. , 910 F.2d 1540, 1546 (7th Cir. 1990) (explaining Teamsters Local 282 ).12

Here, it is established that Perkins (and by extension, Straits Financial) had a fiduciary duty to Ten Sleep, and that he breached this duty by continuing his unauthorized trading "even after Carter instructed him to stop." Dkt. 83 at 6. Perkins breached it again "by failing to disclose this activity to Carter." Id. Since fraud is, of course, an intentional tort under Illinois law, we must not forget that "an action for an intentional tort cannot be defeated by an assertion of negligence on the part of the plaintiff" regardless of whether the fraud claim is brought "at law or in equity." Mother Earth, Ltd. v. Strawberry Camel, Ltd. , 72 Ill.App.3d 37, 28 Ill.Dec. 226, 390 N.E.2d 393, 405 (1979) (citations omitted); see also Roda v. Berko , 401 Ill. 335, 81 N.E.2d 912, 916 (1948) ("where there is an intentional and deliberate fraud ... it is not the privilege of the perpetrator of the fraud to interpose the defense that the one defrauded was not sufficiently careful to discover the fraud and prevent its accomplishment"); see also Williams Electronics Games, Inc. v. Garrity , 366 F.3d 569, 573 (7th Cir. 2004) (same). In light of Continental Concrete Pipe and Teamsters Local 282 , this is true whether the defrauding party seeks complete relief from liability or only partial *377relief from the full measure of damages.13 Because the district court held Carter and Ten Sleep to the wrong legal standard for mitigation of damages, that portion of the district court's judgment must be reversed and remanded for recalculation of Ten Sleep's damages, and a supplemental fee award for appellate work may be needed.

The judgment of the district court as to the parties' liabilities and its award of attorney fees are AFFIRMED. The district court's award of damages to Ten Sleep is REVERSED because of the erroneous reliance on the doctrine of mitigation of damages, and on that issue, we REMAND the case for further proceedings consistent with this opinion.
