Opinion by Judge THOMPSON; Partial Dissent by Judge REINHARDT.

Noble Metals International, Inc.; Moor-gate Ltd.; Richard Schulze, a principal of Moorgate and assistant secretary of Noble; and Richard Portaro, Jr., Moorgate’s former sales manager, (collectively defendants) appeal the district court’s grant of summary judgment in favor of the Commodity Futures Trading Commission (the CFTC or the Commission). The district court held that the defendants violated section 4(a) of the Commodity Exchange Act (the CEA ór the Act), 7 U.S.C. § 6 (a) (1988), by offering and selling to the public illegal “off-exchange” futures contracts. The district court also held the defendants committed fraud in connection with such sales, in violation of section 4b of the Act, 7 U.S.C. § 6b (1988).

The defendants contend the contracts which were sold to the public were not futures contracts, but rather cash forward contracts, which are excluded from the CFTC’s jurisdiction. Noble and Moorgate further contend the district court erred in prohibiting payment of attorney fees from their frozen assets. 1

In addition to joining in Noble’s and Moor-gate’s arguments, the individual defendants, Schulze and Portaro, offer additional arguments of their own. Schulze argues he is entitled to the defenses of estoppel, laches and statute of limitations. We have examined Schulze’s individual arguments and conclude they are meritless.

Portaro argues the district court erred in granting summary judgment against him under section 4(a) of the Act, because he neither created nor maintained the contracts, and relied in good faith on legal opinions that the contracts complied with the Act. He also argues the district court erred in granting *769 summary judgment against him under section 4b of the Act, because genuine issues of material fact exist as to whether he had the necessary intent to defraud.

We affirm the district court’s grant of summary judgment against all of the defendants on the section 4(a) count, and against all of the defendants except Portaro on the section 4b count. We also affirm the district court’s denial of the request for payment of attorney fees from Noble’s and Moorgate’s frozen assets, and the district court’s permanent injunction.

FACTS

Beginning in November 1989, Noble and Moorgate offered and sold contracts for the purchase and sale of precious metals to members of the general public under a program known as the “Forward Delivery Program.” For a 15% “administrative fee,” Forward Delivery Program customers obtained the right and the obligation to make or take delivery of specified quantities of precious metals at a price agreed upon at the time of formation of the Forward Delivery Program contract. After contacting a customer, Noble’s and Moorgate’s salespeople would send out a package of documents, including “Confirmation of Purchase/Sale” and “Terms and Conditions of Purchase and Sale.” These documents described the program in pertinent part:

Noble and Moorgate arranged for certain companies to act as “third-party agents” for the receipt and delivery of metals on behalf of their customers. Under this arrangement, a customer would receive legal title in the form of an invoice when he remitted the full purchase price. Instead of taking physical delivery, however, the customer would contract for the third party to receive, and then to sell, the metal. As a practical matter no actual metal would change hands; the third party would simply sell the metal back to Noble in a paper transaction. The third party would then receive a percentage fee, and the customer would receive the proceeds from the sale.

Noble and Moorgate continued to offer their Forward Delivery Program to customers until September 1991. In January 1992, the CFTC filed its complaint in this ease. The CFTC sought injunctive and ancillary equitable relief, including a temporary restraining order, preliminary and permanent injunctions, a freeze of the defendants’ assets, an accounting, disgorgement, restitution, and the appointment of a receiver.

On May 11, 1993, the district court issued an order adopting a report and recommendation of the magistrate judge that sanctions be imposed on Noble and Moorgate for failure to comply with certain discovery orders. The Commission had served Noble and Moorgate with notices of depositions pursuant to Federal Rule of Civil Procedure (Rule) 30(b)(6), scheduling depositions for July 8, 1992. On the deposition date, only defense counsel appeared because Noble and Moor-gate had failed to designate any deposition representative. Their counsel assured the CFTC that appropriate designations would be made, and the depositions were rescheduled. At the next scheduled deposition date, Schulze, a principal officer of Noble, appeared on behalf of Noble and Moorgate. He invoked his Fifth Amendment privilege against self-incrimination, and refused to answer any relevant questions.

*770 In ruling on the Commission’s subsequent motion to compel, the magistrate judge found Noble and Moorgate had representatives available to them who would not invoke their Fifth Amendment privilege and that Noble and Moorgate had not made a good faith effort to locate a suitable representative. The magistrate judge then imposed a $500 sanction, and ordered the corporations to “designate a person to represent them, pursuant to Fed.R.Civ.P. 30(b)(6), who will not invoke the fifth amendment ‘privilege.” (emphasis added).

The sanction was never paid. Rather than designate an appropriate representative, seek reconsideration of the order, or seek a protective order, Noble and Moorgate merely provided a list of persons who, for various reasons, would not testify. They then designated Schulze as their representative, knowing he would invoke the privilege against self-incrimination.

The Commission moved for sanctions in January 1993. In response, Noble and Moorgate for the first time sought a protective order. After receiving the pleadings, the magistrate judge ordered the corporations to explain “how responding to the area of inquiry would place either Defendant in danger of self-incrimination.” Neither Noble nor Moorgate responded. 2 Based on its adoption of the magistrate judge’s findings, and pursuant to Rule 37(b)(2)(A), the district court ruled that all allegations of the complaint would be established as true against Noble and Moorgate.

The court granted a temporary restraining order and later issued a preliminary injunction. Both sides moved for summary judgment. The district court granted summary judgment in favor of the CFTC, and denied the defendants’ motion for summary judgment. The district court also issued a permanent injunction against Noble and Schul-ze, appointed a permanent receiver over Noble’s and Moorgate’s already-frozen assets, and ordered the individual defendants to disgorge profits made from the sale of the Forward Delivery Program contracts. This appeal by Noble, Moorgate, Portaro and Schulze followed. 3

DISCUSSION

A. Summary Judgment

1. Against Noble and Moorgate

In granting summary judgment against Noble and Moorgate, the district court relied on the allegations of the complaint which it accepted as established. It did this pursuant to the sanction it had imposed for violation of the court’s discovery order. On appeal, Noble and Moorgate contend the district court abused its discretion by imposing such a harsh sanction.

Rule 37(b)(2) provides in pertinent part:

Fed.R.Civ.P. 37(b)(2).

Sanction orders taking the plaintiffs allegations as established and awarding judgment on that basis are “the most severe *771 penalty,” and are authorized only in extreme circumstances.” United States ex rel. Wiltec Guam, Inc. v. Kahaluu Constr. Co., 857 F.2d 600, 603 , 603 n. 5 (9th Cir.1988) (citing Fjelstad v. American Honda Motor Co., 762 F.2d 1334, 1338 (9th Cir.1985)). To justify the imposition of such a harsh sanction, the district court must find that the violations were “due to willfulness, bad faith, or fault of the party.” Id. at 603 (quoting Wyle v. R.J. Reynolds Indus., Inc., 709 F.2d 585 , 589 (9th Cir.1983)). However, “[i]n reviewing the sanction, the question is not whether we would have imposed a different sanction had we considered the matter originally, but whether the district court ‘exceeded the limits of its discretion.’ ” Id. (quoting Halaco Eng’g Co. v. Costle, 843 F.2d 376 , 379 (9th Cir.1988)).

Both the magistrate judge and the district court specifically found that Noble and Moor-gate willfully violated the court’s orders by repeatedly failing to designate a representative who would testify at a discovery deposition. Noble and Moorgate argue there was no officer, director or managing agent available to testify, either because they were no longer employed by Noble and Moorgate, they would invoke the Fifth Amendment privilege, or they otherwise would not consent to testify.

Noble and Moorgate, however, made no showing of any good faith attempt to designate an available representative. The list they submitted, purportedly in response to the magistrate judge’s November 9, 1992 order, lists only six individuals, all of whom could not testify for one reason or another. Significantly, Moorgate alone employed at least 148 people. In addition, by their own admission Noble and Moorgate never contacted some of the very “witnesses” they listed in their designation. For some of these witnesses, they merely stated summarily that the witnesses refused to testify, without explaining the basis for the witnesses’ refusal.

Had Noble and Moorgate truly been unable to designate a representative, they could have sought a protective order. See United States v. Kordel, 397 U.S. 1, 9 , 90 S.Ct. 763, 768 , 25 L.Ed.2d 1 (1970) (appropriate remedy where a corporation finds it has no agents who can testify without invoking the privilege is a protective order under Rule 30(b)). By eschewing any application for such an order, and instead declining to make an appropriate designation of someone to testify, Noble and Moorgate engaged in a calculated course of conduct. See Adriana Int’l Corp. v. Thoeren, 913 F.2d 1406, 1411 (9th Cir.1990), cert. denied, 498 U.S. 1109 , 111 S.Ct. 1019 , 112 L.Ed.2d 1100 (1991); cf. Fjelstad, 762 F.2d at 1343 . This conduct was willful.

In addition to willfulness, when a court order is violated, as in this case, a district court that decides to impose sanctions must consider the risk of prejudice to the defendants and the availability of less drastic sanctions. Adriana, 913 F.2d at 1412 . Here, both factors favor the district court’s sanction.

Noble and Moorgate’s willful refusal to comply with the court’s order severely prejudiced the government’s ability to make its case. See id. (finding that “the repeated failure of [the corporate party] to appear at scheduled depositions ... constitute[d] an interference with the rightful decision of the case”); see also Hyde & Drath v. Baker, 24 F.3d 1162, 1167 (9th Cir.1994) (finding that failure of corporation to appear at depositions prejudiced opposing party).

The district court also considered lesser sanctions. On November 10, 1992, the magistrate judge imposed a sanction of $500 on Noble and Moorgate. Although apparently the court never warned Noble and Moorgate that their continued intransigence would result in the harsh sanction eventually imposed, a warning was not necessary in this case. First, Noble and Moorgate could not have been surprised by the severity of the sanction. See Adriana, 913 F.2d at 1413 (no explicit warning necessary when harsh sanction of dismissal should not have surprised party who willfully violated court’s order); Malone v. U.S. Postal Serv., 833 F.2d 128, 133 (9th Cir.1987), cert. denied, 488 U.S. 819 , 109 S.Ct. 59 , 102 L.Ed.2d 37 (1988) (same). When seeking the original monetary sanction and order to compel, the CFTC explicitly expressed its intention to seek more severe sanctions, including default judgment, if No *772 ble and Moorgate failed to comply with the court’s discovery order.

Second, the circumstances surrounding the sanction were egregious. See id. at 132-33 . Not only did Noble and Moorgate violate a court order and fail to pay the earlier $500 sanction, they did not seek a protective order even though they had six months to do so. The record also indicates this was not the first time these defendants engaged in dilatory tactics.

We conclude the district court did not abuse its discretion in imposing its Rule 37(b)(2) sanction ordering that the allegations of the complaint be taken as established for the purposes of the action.

Noble and Moorgate argue that even taking all of the allegations of the complaint as true, they did not violate sections 4(a) or 4b of the Act because, they contend, the Forward Delivery Program contracts they sold were not “futures contracts” regulated by the Act. We disagree.

Under section 2(a)(1)(A) of the Act, the CFTC has exclusive jurisdiction over “accounts, agreements ... and transactions involving contracts of sale of a commodity for future delivery, traded or executed on a contract market.” 7 U.S.C. § 2 . The Act requires that these “futures contracts” be offered and sold on commission-designated boards of trade, or they are deemed illegal “off-exchange” contracts. In re Bybee, 945 F.2d 309, 312 (9th Cir.1991) (citing 7 U.S.C. § 6 (a)).

A futures contract enables an investor to hedge the risk that the price of the commodity will change between the date the contract is entered and the date delivery is due— without having to take physical delivery of the commodity. CFTC v. Co Petro Mktg. Group, Inc., 680 F.2d 573, 579-80 (9th Cir.1982). A futures contract provides that a specific amount of the commodity will be “delivered” to the buyer at a specified date (trade date) at an agreed-upon price. If the buyer does not want to take delivery of the commodity on the trade date, he enters an “off setting transaction” to sell the same amount of the commodity. Id. The investor’s profit or loss depends upon the difference between the amount the investor contracted to pay for the commodity and what he gets for it when he sells it.

Excluded from the definition of futures contracts, and thus from CFTC jurisdiction, are “cash forward contracts,” which are “any sale of any cash commodity for deferred shipment or delivery.” 4 7 U.S.C. § 2 . This “narrow” exclusion is predicated on both parties contemplating and intending future delivery of the actual commodity when immediate delivery would be commercially impracticable. 5 Co Petro, 680 F.2d at 578 ; see also In re Bybee, 945 F.2d at 313 (citing In re Stovall, [1977-1980 Transfer Binder], Comm. Fut.L.Rep. (CCH) ¶ 20,941, at 23,777-778).

Noble contends the Forward Delivery Program contracts it sold were cash forward contracts, not futures contracts, and thus were exempt from CFTC jurisdiction. We disagree. The cash forward contract exclusion is “unavailable to contracts of sale for commodities which are sold merely for speculative purposes and which are not predicated upon the expectation that delivery of the actual commodity by the seller to the original contracting buyer will occur in the future.” Co Petro, 680 F.2d at 579 .

It is undisputed that among the vast number of purchasers of metals under the Forward Delivery Program offered by Noble and Moorgate, only a handful contemplated actual delivery. Noble and Moorgate contend that they satisfied the “delivery” requirement nonetheless, because the contracts required the buyer to “take or make delivery of the merchandise contracted.” According to Noble and Moorgate, they satisfied this requirement by transferring, i.e., “delivering,” title to the metals to the investor; the metals *773 may have been held by the third-party depository, but the investor owned the metals, as reflected by his documents of title, and thus he had taken delivery.

We reject this argument. To take advantage of the cash forward contract exclusion under the Act, the delivery requirement cannot be satisfied by the simple device of a transfer of title. As we said in Co Petro, “a cash forward contract is one in which the parties contemplate physical transfer of the actual commodity.” Co Petro, 680 F.2d at 578 . If this were not so, the cash forward contract exception would quickly swallow the futures contract rule.

“[S]elf-serving labels that the defendants choose to give their contracts should not deter the conclusion that their contracts, as a matter of law, [are futures contracts subject to the CEA].” American Metal Exch. Corp., 693 F.Supp. 168, 192 (D.N.J.1988) (quoting CFTC v. Morgan, Harris, & Scott Ltd., 484 F.Supp. 669, 675 (S.D.N.Y.1979)). Here, there was no legitimate expectation that Noble’s and Moorgate’s customers would take actual delivery of the metal they bought. The Forward Delivery Program contracts, therefore, were futures contracts subject to the Commission’s jurisdiction, and when Noble and Moorgate sold them in off-exchange transactions they violated section 4(a) of the Act.

The district court did not err in granting summary judgment against Noble and Moor-gate on this count. Nor did it err in granting summary judgment against them on the section 4b count. Taking the allegations of the complaint as established, Noble and Moorgate’s sales of the Forward Delivery Program contracts were fraudulent within the meaning of section 4b.

2. Summary Judgement Against Schulze and Portaro

As we have previously stated, Schulze’s individual arguments on appeal are meritless. We have also rejected Noble’s and Moor-gate’s arguments, in which Schulze joins. We conclude, therefore, that the district court did not err in granting summary judgment against Schulze on the sections 4(a) and 4b counts.

Portaro, who was the former sales manager of Moorgate, argues summary judgment should not have been entered against him on the CFTC’s allegations that he violated sections 4(a) and 4b of the Act, because there is at least a genuine issue of material fact whether scienter was established against him.

That section 4(a) does not require proof of scienter has been settled, at least implicitly, by our court. See Co Petro, 680 F.2d at 582 . A review of the statutory language confirms this conclusion. Section 4(a) provides:

7 U.S.C. § 6 (a) (1988). Section 4(a) makes no mention of scienter. Compare 7 U.S.C. § 6b (1988).

Section 13c further supports this reading. Section 13c provides in pertinent part:

7 U.S.C. § 13c(a) (1988).

In contrast to the provisions for aider and abetter liability, section 13c does not require scienter when, as here, the defendant directly commits the violation. Furthermore, even if Portaro’s actions merely constituted aiding and abetting, his willful violation of the Act is established indisputably by the record in this case. Portaro was the sales manager for Moorgate. He hired the salespeople who sold the Forward Delivery Program contracts, was responsible for their compliance and training, and supervised sales of the contracts to customers. He also offered and sold Forward Delivery Program contracts to members of the general public.

We can accept as true Portaro’s contention that he relied in good faith on the opinion of counsel that the Forward Delivery Program contracts complied with the Act and he did not intend to do anything wrong. This is irrelevant in a section 4(a) case, because scienter is not an element of the offense. 6 It is enough that Portaro willfully did those things proscribed by the Act. See Lawrence v. CFTC, 759 F.2d 767, 773 (9th Cir.1985) (finding willfulness established under the CEA “[i]f a person (1) intentionally does an act which is prohibited,-irrespective of evil motive or reliance on erroneous advice, or (2) acts with careless disregard of statutory requirements”).

With regard to the section 4b claim, however, scienter is an element. 7 The Commission must show Portaro intentionally violated the Act or acted with “careless disregard” of whether his actions violated the Act. Lawrence, 759 F.2d at 773 ; CFTC v. Savage, 611 F.2d 270, 283 (9th Cir.1979). “Mere negligence, mistake, or inadvertence fails to meet Section 4b’s scienter requirement.” Wasnick v. Refco, Inc., 911 F.2d 345, 348 (9th Cir.1990) (citing Drexel, Burnham Lambert, Inc. v. CFTC, 850 F.2d 742, 748 (D.C.Cir.1988)).

Here there is a genuine issue of material fact whether Portaro acted with the requisite scienter to establish fraud. The record is replete with references to his efforts to run a legitimate sales operation. For example, various salespeople attested that Portaro forbade them from misrepresenting any aspect of the Forward Delivery Program to their customers. Furthermore, there is no direct evidence that he intended to defraud anyone.

Because there is a genuine dispute of material fact whether Portaro acted with the requisite scienter for a violation of section 4b of the Act, we reverse the district court’s grant of summary judgment against him on that count.

B. The Asset Freeze

In the initial phases of the litigation, the court froze the assets of each of the defendants, first as part of the temporary *775 restraining order, and later as part of the preliminary injunction. 8 Shortly after the complaint was filed, counsel for Noble and Moorgate applied for payment of their attorney fees from the frozen assets. The district court denied this application. As a result, Noble and Moorgate were precluded from using the frozen assets to pay their attorney fees throughout the litigation.

A district court may, within its discretion, forbid or limit payment of attorney fees out of frozen assets. See FSLIC v. Ferm, 909 F.2d 372, 375 (9th Cir.1990) (approving limitation on attorney fees); see also FTC v. World Wide Factors, Ltd., 882 F.2d 344 , 347 (9th Cir.1989) (observing that “[c]ourts regularly have frozen assets and denied attorney fees or limited the amount for attorney fees”); cf. CFTC v. Co Petro Mktg. Group, Inc., 700 F.2d 1279 , 1284 (9th Cir.1983) (Co Petro II) (requiring counsel to return fee received after defendants’ assets were frozen for violating futures trading regulations).

According to the record, the frozen assets fell far short of the amount needed to compensate Noble’s and Moorgate’s customers. This was reason enough in the circumstances of this case for the district court, in the exercise of its discretion, to deny the attorney fee application. See World Wide Factors, 882 F.2d at 348 (approving limitation on attorney fees “out of concern for preserving funds for ultimate distribution to defrauded customers”) (citing FSLIC v. Dixon, 835 F.2d 554 , 564-65 (5th Cir.1987)); accord CFTC v. Morse, 762 F.2d 60 , 63 (8th Cir.1985). We do not, however, intimate that attorney fee applications may always be denied where the assets are insufficient to cover the claims. Discretion must be exercised by the district court in light of the fact that wrongdoing is not yet proved when the application for attorney fees is made. Cf. Dixon, 835 F.2d at 565.

CONCLUSION

The district court’s grant of summary judgment against all defendants for violating section 4(a) of the Act is affirmed. The district court’s grant of summary judgment is also affirmed against all defendants except Portaro for violating section 4b of the Act. The district court’s summary judgment against Portaro for violating section 4b of the Act is reversed. The district court’s denial of the application for the payment of attorney fees from frozen assets and the district court’s permanent injunction are affirmed.

AFFIRMED in part, REVERSED in part and REMANDED.

. Another issue raised by Noble and Moorgate— whether the district court erred by failing to conduct a third hearing before granting the preliminary injunction — is mooted by our decision on the merits.

. In their objections to the magistrate judge's report and recommendation, Noble and Moor-gate contended they never received the minute order. The district court rejected this contention, noting that even if true, Noble and Moor-gate could have included the necessary information in their objections.

. In addition to the parties' briefs, we have also carefully considered briefs submitted by amicus curiae, Noble Customers Association.

. The terms "futures contracts” and "cash forward contracts” are terms of art which do not appear in the Act.

. Congress created the cash forward contract exclusion for farmers who wanted to sell part of the next season’s harvest at a set price to a grain elevator or miller. Co Petro, 680 F.2d at 577 . In such a transaction, both parties are guaranteed a price, but delivery is delayed until the miller or elevator has the capacity to process the wheat. Id.

. Nonetheless, "good faith reliance on the advice of counsel is ... a factor in determining the propriety of injunctive relief.” Securities and Exchange Commission v. Steadman, 967 F.2d 636, 648 (D.C.Cir.1992); cf. also Aaron v. SEC, 446 U.S. 680, 701 , 100 S.Ct. 1945, 1958 , 64 L.Ed.2d 611 (1980) (in applying provisions of the Securities Act of 1933 which do not require proof of scienter, "a district court may consider scienter or lack of it as one of the aggravating or mitigating factors to be taken into account in exercising its equitable discretion in deciding whether or not to grant injunctive relief”). The district court took this factor into account by declining to issue a permanent injunction against Portaro.

. Section 4b provides in pertinent part:

7 U.S.C. § 6b(A).

. The court allowed the individual defendants to expend funds "for ordinary, reasonable, and necessary living expenses," from their frozen assets. Neither Schulze nor Portaro appeal the asset freeze.
