KAREN LeCRAFT HENDERSON, Circuit Judge:

Paul A. Bilzerian appeals two district court orders entered against him in favor of the Securities and Exchange Commission (SEC). First, Bilzerian appeals the order granting partial summary judgment to the SEC on its claims that Bilzerian violated numerous securities laws and permanently enjoining him from further violations. Second, Bilzerian challenges the order that he disgorge $33,140,787, representing the profit he obtained from his securities law violations. 814 F.Supp. 116. We affirm both orders.

I.

Before the commencement of this civil action, Bilzerian was convicted in the United States District Court for the Southern District of New York of numerous violations of the federal securities laws. He was sentenced to four years in prison, fined $1.5 million dollars and ordered to perform 250 hours of community service. The Second Circuit affirmed Bilzerian's convictions in all respects. See United States v. Bilzerian, 926 F.2d 1285 (2d Cir.), cert. denied, ___ U.S. ___, 112 S.Ct. 63, 116 L.Ed.2d 39 (1991).

The same conduct that led to Bilzerian's criminal convictions forms the basis of the SEC's civil action against him. In 1985 and 1986, Bilzerian accumulated substantial blocks of stock in Cluett, Peabody and Company (Cluett) and Hammermill Paper Company (Hammermill) through a stock accumulation agreement with Jefferies Company (Jefferies), a broker-dealer registered with the SEC. Under the terms of the accumulation agreement, Jefferies purchased stock in its own account and Bilzerian agreed to buy the stock on a specific future date at Jefferies' cost plus interest and commissions. Although Bilzerian was the beneficial owner of the stock at all times after the agreement was entered into, Jefferies remained the record owner until the date on which Bilzerian bought the stock. Bilzerian used his stock accumulation agreement with Jefferies to conceal the extent of his ownership of Cluett and Hammermill stocks in order to delay filing a required form, Schedule 13D, with the SEC. When Bilzerian eventually disclosed his accumulations of Cluett and Hammermill stocks to the SEC, he misrepresented the source of funds used to purchase the stocks. Bilzerian certified that he had used "personal funds" to purchase the stocks when in fact he had obtained the funds from investors whom he had guaranteed against losses and granted a share in his profits. Bilzerian repeated the misrepresentations on the Schedule 14D-1 form he subsequently filed with the SEC.

Bilzerian's misrepresentations were designed to create the impression that he was ready, willing and able to mount hostile takeovers of Cluett and Hammermill — if shareholders had known that Bilzerian had indemnified his investors against any losses, they would have questioned his financial ability to effectuate a hostile takeover. The purpose of Bilzerian's scheme was to induce a "white knight" to rescue the companies from his hostile takeover by purchasing stock, including his own, at a premium. The scheme succeeded — Bilzerian sold his Cluett stock and his Hammermill stock at a substantial profit.

Bilzerian's convictions were also based on his "parking" of H.H. Robertson Company (H.H. Robertson) and Armco Steel (Armco) stock with Jefferies. Under two separate "stock parking" agreements between Bilzerian and Jefferies, Jefferies bought stock from Bilzerian with the understanding that Bilzerian would buy the stock back on a future date for the purchase price plus interest and commission. These agreements, like Bilzerian's accumulation agreements, served the purpose of concealing his beneficial ownership of the stock. In order to mask the agreements, Bilzerian and Jefferies exchanged a number of false invoices.

The district court issued two orders that Bilzerian now appeals. The first order granted partial summary judgment to the SEC on its claims that Bilzerian had violated certain securities laws and regulations and accordingly enjoined Bilzerian from future violations. The court based its grant of summary judgment on the collateral estoppel effect of Bilzerian's criminal convictions. In its second order, the court ordered disgorgement of Bilzerian's illicit profits.

Bilzerian argues: (1) collateral estoppel was improperly applied by the trial court because his criminal convictions did not conclusively establish the facts necessary to conclude that he had committed the violations with which he was charged in this action; (2) the court erred in issuing a permanent injunction on the SEC's motion for summary judgment because genuine issues of material fact existed; (3) the disgorgement order violates the double jeopardy clause of the fifth amendment; and (4) the court erred in calculating the amount to be disgorged.

II.

Based on the collateral estoppel effect of Bilzerian's criminal convictions, the district court entered summary judgment on the SEC's claims that Bilzerian aided and abetted Jefferies' violation of section 7(c) and Regulation T and that Bilzerian himself violated sections 7(f), 10(b), 13(d), 14(d), 14(e) and 17(a)(1) of the Act; SEC Rules 10b-5, 13d-1, 13d-2, 14d-3, 14d-6, and 17a-3 promulgated under the Act; and Regulation X. The doctrine of collateral estoppel prohibits relitigation of an issue of fact or law that has been decided in earlier litigation. Parklane Hosiery Co. v. Shore, 439 U.S. 322, 326 n. 5, 99 S.Ct. 645, 649 n. 5, 58 L.Ed.2d 552 (1979). The district court found that Bilzerian was collaterally estopped from contesting the facts set forth in support of the SEC's civil claims because the same facts formed the basis of his criminal conviction. Appendix (App.) of SEC at 792. Bilzerian argues that the facts the SEC had to establish to prevail in its civil action were either not litigated in his criminal case or were not necessary to his convictions.

Specifically, Bilzerian argues that the district court erred in holding that his section 10(b) convictions estop him from challenging his civil liability under sections 13(d), 14(d) and 14(e) of the Act because the jury did not necessarily find that his misrepresentations were material as the SEC is required to establish under those sections. We disagree. Bilzerian appealed his criminal convictions on the ground that his misrepresentations and omissions were not material. The Second Circuit rejected his argument explaining that "[a]fter hearing the evidence in this case, the jury concluded that the misstatements and omissions were material." United States v. Bilzerian, 926 F.2d 1285, 1298-99 (2d Cir. 1991). The Second Circuit's holding conclusively establishes the materiality of Bilzerian's misstatements and omissions; his argument that collateral estoppel is inappropriate because the jury never determined materiality accordingly fails.

Bilzerian also argues that his convictions did not establish the facts necessary to support the SEC's civil claims that he violated margin requirements (Seventh Claim, App. of SEC at 1197 ¶ 154-56), aided and abetted Jefferies' margin violations (Eighth Claim, App. of SEC at 1197-98 ¶ 157-61) and aided and abetted Jefferies' falsification of records (Sixth Claim, App. of SEC at 1196 ¶ 149-53). Our review of the record indicates that Bilzerian's criminal convictions conclusively established all of the facts the SEC was required to prove with respect to the specified claims. Accordingly, we affirm the district court's grant of partial summary judgment.

III.

We review de novo the district court's grant of summary judgment to the SEC on its request for permanent injunctive relief. When a defendant has violated the securities laws, an injunction is appropriate if the court determines there is a reasonable likelihood that he will violate the laws again in the future. See SEC v. First City Fin. Corp., 890 F.2d 1215, 1228 (D.C. Cir. 1989). In order to determine whether a reasonable likelihood of future violations exists, the court considers "whether a defendant's violation was isolated or part of a pattern, whether the violation was flagrant and deliberate or merely technical in nature, and whether the defendant's business will present opportunities to violate the law in the future." Id.

There is no genuine issue of material fact regarding whether Bilzerian's securities violations were part of a pattern or whether they were flagrant and deliberate in nature; they unquestionably were, as the brief summary of his conduct set forth earlier manifests. Courts have often found that the combination of these two factors justifies injunctive relief prohibiting future violations of the securities laws. See, e.g., SEC v. Blatt, 583 F.2d 1325, 1334-35 (5th Cir. 1978) (nature and extent of securities violations warranted injunction); SEC v. Management Dynamics, Inc., 515 F.2d 801, 807 (2d Cir. 1975) (serious and intentional nature of defendant's conduct warranted injunction). Accordingly, we agree with the district court that injunctive relief is appropriate.

Bilzerian argues, however, that a genuine issue of material fact exists regarding whether his occupation provides him an opportunity to violate the securities laws. We disagree. Even assuming Bilzerian is correct, that circumstance would not make injunctive relief inappropriate. See SEC v. Koracorp Indus., 575 F.2d 692 (9th Cir.) (changing occupations so that opportunity for securities laws violations is not readily available does not necessarily defeat injunctive relief), cert. denied, 439 U.S. 953, 99 S.Ct. 348, 58 L.Ed.2d 343 (1978). Moreover, the nature of Bilzerian's past violations indicates that, notwithstanding a change in occupation, he will nonetheless be able to violate the securities laws. Bilzerian's securities laws violations did not arise from a position of authority in a brokerage firm, or from any other position for that matter. They resulted from actions he took as an investor. Bilzerian will be able to commit similar violations so long as he is able to persuade people to finance his schemes.

Bilzerian also argues that he has given the court sufficient assurances against future violations to remove the need for a permanent injunction. Bilzerian's argument relies on his affidavit filed in the district court in which he declares that he "will be careful and make every effort to assure that [he does] not violate the federal securities law in the future." See App. of SEC at 478. If a defendant could survive summary judgment by simply submitting a self-serving statement about his desire to conform to the law in the future, it "would establish . . . a ritualistic dodge around a permanent injunction on a motion for summary judgment." SEC v. Murphy, 626 F.2d 633, 656 (9th Cir. 1980). We do not intend to provide Bilzerian with any such dodge. Because the other relevant factors counsel in favor of injunctive relief, Bilzerian's assertions do not alter our conclusion that summary judgment was appropriate.

Finally, Bilzerian argues that the district court was required to hold a hearing before entering a permanent injunction against him. Courts have approved the entry of a permanent injunction, however, on a motion for summary judgment based wholly on the facts established by the defendant's prior criminal conviction. See SEC v. Gruenberg, 989 F.2d 977 (8th Cir. 1993) (injunction granted on summary judgment based on collateral estoppel effect of criminal convictions of securities laws violations); SEC v. Everest Management Corp., 466 F.Supp. 167 (S.D.N.Y. 1979) (same). Accordingly, we affirm the district court's grant of injunctive relief.

IV.

Bilzerian alleges that the disgorgement order violates the double jeopardy clause of the fifth amendment because it punishes him for the same conduct that led to his criminal convictions. The double jeopardy clause is violated when multiple punishments are imposed for the same offense. See Schiro v. Farley, ___ U.S. ___, ___, 114 S.Ct. 783, 789, 127 L.Ed.2d 47 (1994). Bilzerian's imprisonment resulting from his convictions unquestionably constitutes punishment so that the only issue is whether the disgorgement order constitutes renewed punishment for the same conduct.

Bilzerian bases his argument on the Supreme Court's decision in United States v. Halper, 490 U.S. 435, 109 S.Ct. 1892, 104 L.Ed.2d 487 (1989). He specifically relies on the Court's statement in Halper that "a civil sanction that cannot fairly be said solely to serve a remedial purpose, but rather can only be explained as also serving either retributive or deterrent purposes, is punishment." Accordingly, he argues that, because disgorgement is not solely remedial but also a type of deterrence, it is punishment within the meaning of the double jeopardy clause. We find Bilzerian's reliance on Halper misplaced.

The reach of the Halper decision is short. As the Court explained: "What we announce now is a rule for the rare case, the case such as the one before us, where a fixed penalty provision subjects a prolific but small-gauged offender to a sanction overwhelmingly disproportionate to the damages he has caused." Because the disgorgement order did not ask Bilzerian to give up anything in excess of the amount of his illicit gains, Bilzerian does not present "the rare case" contemplated by the Court in Halper. Accordingly, we conclude that the disgorgement order is remedial in nature and does not constitute punishment within the meaning of double jeopardy.

Finally, we reject Bilzerian's argument that disgorgement constitutes punishment unless it is ordered to make the government whole. Disgorgement is no less remedial in nature merely because victims other than the government have been injured by Bilzerian's violations of the securities laws. The district court ordered Bilzerian to give up only his illgotten gains; it did not subject him to an additional penalty. Therefore the disgorgement does not constitute punishment. See United States v. Tilley, 18 F.3d 295, 300 (5th Cir. 1994) ("[T]he forfeiture of illegal proceeds, much like the confiscation of stolen money from a bank robber, merely places that party in the lawfully protected financial status quo that he enjoyed prior to launching his illegal scheme. This is not punishment within the plain meaning of the word.") (internal citation omitted).

V.

Finally, Bilzerian mounts two other challenges to the disgorgement order. Bilzerian first argues that disgorgement was not appropriate because he did not profit from his violations of the securities laws. This argument rests on a fundamental misunderstanding of the reason the district court ordered disgorgement. Bilzerian asserts that the district court found disgorgement appropriate because his misrepresentations suppressed the market price of the stock in question and he was therefore able to purchase stock at an artificially lower price; accordingly, he should disgorge the resulting profit. As Bilzerian sees it, the district court erred in ordering disgorgement because he did not purchase any stock after his alleged misrepresentations and so he could not have profited from any purchase price decrease caused by his misrepresentations.

But the district court found that Bilzerian's misrepresentations inflated the price he received from the sale of the securities. See App. of SEC at 1149-50. If Bilzerian had disclosed the truth about his stock purchases and source of funding, the market would have discounted his ability to take over the target corporations. By failing to make these disclosures, Bilzerian created the impression that hostile takeovers were imminent, thereby driving up the price of the target corporations' securities. Accordingly, the district court ordered Bilzerian to disgorge the difference between the price he received for the sale of his shares — inflated artificially by his false filings with the SEC — and the price the shares would have brought were it not for his untimely and misleading filings. App. of SEC at 1149-50. Bilzerian's argument that he purchased no stock after making his misrepresentations is therefore irrelevant.

Bilzerian also argues that the district court incorrectly calculated the amount of the disgorgement ($33,140,787.00). We will uphold the district court's disgorgement calculation unless it constitutes clear error. SEC v. First City Fin., 890 F.2d 1215, 1228 (D.C. Cir. 1989). We find that the district court's disgorgement order reasonably approximated Bilzerian's illicit profits. The court was careful to order disgorgement of the profits caused by Bilzerian's securities violations only. For the shares Bilzerian purchased after his securities violations occurred, the court subtracted Bilzerian's purchase price from the price at which he later sold the stocks based on the theory that all appreciation occurring after his violations was due to his illegal actions. For the shares purchased before his violations, the court subtracted from the sales price the market price on the first day of his violations, thereby ensuring that any pre-violation appreciation was not disgorged.

Calculations of this sort are often imprecise — it is impossible to say with certainty what portion of Bilzerian's profits is attributable to his securities violations. Bilzerian, however, bears the burden of establishing that the price increases that occurred during his ownership of the stocks were attributable to market forces rather than to his violations. See First City Fin., 890 F.2d at 1232. He failed to carry his burden. Absent proof of this sort, the district court's calculation of the disgorgement amount was not clearly erroneous.

Finally, Bilzerian argues that disgorgement was not proper because no one was injured by his fraudulent schemes. We disagree. Whether or not Bilzerian's securities violations injured others is irrelevant to the question whether disgorgement is appropriate. The primary purpose of disgorgement is not to refund others for losses suffered but rather "to deprive the wrongdoer of his ill-gotten gain." SEC v. Blatt, 583 F.2d at 1335. Moreover, others were injured by Bilzerian's deceptions — investors paid Bilzerian an inflated price for his stocks because of his illegal actions.

For the preceding reasons, the decisions of the district court are

Affirmed.
