MR. Justice Stewart
delivered the opinion of the Court.
The False Claims Act provides that the United States may recover from a person who presents a false claim or causes a false claim to be presented to it a forfeiture of $2,000 plus an amount equal to double the amount of damages that it sustains by reason of the false claim. This case presents two interpretative problems that arise when the United States sues a subcontractor under the Act on the ground that the subcontractor has caused the prime contractor to present false claims: First, how should the number of $2,000 forfeitures be counted? Second, when the United States has already recovered damages from the prime contractor because of the subcontractor’s fraud, what effect does that recovery have upon the Government’s right to recover double damages from the subcontractor?
I
In 1962, the United States entered into a $2,100,000 contract with Model Engineering & Manufacturing Corporation, Inc. (Model), for the provision of radio kits. Each kit was to contain electron tubes that met certain specifications. Model subcontracted with United National Labs (United) to supply these tubes at a price of $32 each. The tubes that United sent to Model under this subcontract were not of the required quality, but were falsely marked by United to indicate that they were. United sent at least 21 boxes of these falsely marked tubes to Model, in three separately invoiced shipments. The radio kits that Model in turn shipped to the United States contained 397 of those falsely marked tubes. Model sent 35 invoices to the Government for the radio kits, and each invoice included claims for payment for the falsely marked tubes that had been supplied to Model by United. After the Government discovered the fraud, it recovered $40.72 per tube from Model and also retained the falsely marked tubes.
Subsequently, the Government brought this civil action in a Federal District Court under the False Claims Act against United and two of its owner-officers, the respondents Philip L. Bornstein and Gerald Page. The complaint alleged that United was liable for 35 $2,000 forfeitures — one forfeiture for each invoice that it had “caused” Model to submit, and also claimed damages of $16,205.54, consisting of $40.82 per tube for 397 tubes. The trial court agreed that there had been 35 forfeitures, but ruled that before the Government’s damages could be doubled, they were to be reduced by the amount of Model’s payment to the United States. The court accordingly computed double damages at only $79.40 and awarded the Government a total of $70,079.40. 361 F. Supp. 869 (NJ). On cross-appeals the Court of Appeals agreed with the trial court on the double-damages issue, but concluded that since there had been only one subcontract involved, there should be only one statutory forfeiture. Accordingly, the appellate court held that'United was liable for only $2,079.40. 504 F. 2d 368 (CA3). We granted the Government’s petition for certiorari to consider the statutory questions presented. 420 U. S. 906.
II
The Number of Statutory Forfeitures
The False Claims Act provides that a person “who shall do or commit any of the acts prohibited by” Rev. Stat. § 5438 “shall forfeit and pay to the United States the sum of two thousand dollars . . . Rev. Stat. § 3490. Section 5438 makes it illegal for a person to present or cause to be presented “for payment or approval . . . any claim upon or against the Government of the United States . . . knowing such claim to be false, fictitious, or fraudulent.” It is settled that the Act permits recovery of multiple forfeitures and that it gives the United States a cause of action against a subcontractor who causes a prime contractor to submit a false claim to the Government. See United States ex rel. Marcus v. Hess, 317 U. S. 537. The precise issue presented here is whether the subcontractor should be liable for each claim submitted by its prime contractor or whether it should be liable only for certain identifiable acts that it itself committed.
The legislative history of the Act offers little guidance on how properly to determine the number of forfeitures. The Act was originally aimed principally at stopping the massive frauds perpetrated by large contractors during the Civil War. There is no indication that Congress gave any thought to the question of how the number of forfeitures should be determined in cases involving subcontractor fraud. But the absence of specific legislative history in no way modifies the conventional judicial duty to give faithful meaning to the language Congress adopted in the light of the evident legislative purpose in enacting the law in question.
The respondents defend the decision of the Court of Appeals that held them liable for only one forfeiture. In reaching this conclusion the Court of Appeals relied principally on its earlier decision in United States v. Rohleder, 157 F. 2d 126 (CA3), where it found that 16 forfeitures were appropriate because 16 contracts were involved. The Rohleder court had relied in turn on this Court's decision in United States ex rel. Marcus v. Hess, supra. The Hess case involved several electrical contractors who had collusively bid on 56 Public Works Administration projects. The District Court in Hess had imposed 56 forfeitures, rejecting the defendants’ claim that only one forfeiture should have been imposed because there had been only one fraudulent scheme. This Court concluded that the District Court was correct because the incidence of fraud on each separate project was clearly individualized. 317 U. S., at 552. No party argued in this Court that more than 56 forfeitures should have been imposed, and no statement in the Hess opinion expressly limited the number of imposable forfeitures to the number of contracts involved in a case. Hess simply approved the result reached by the District Court which had found that “in each project there was a single, false, or fraudulent claim.” 41 F. Supp. 197, 216 (WD Pa.).
The Hess case, therefore, in no way stands for the proposition that the number of forfeitures is inevitably measured by the number of contracts involved in a case. Such an automatic measurement would ignore the plain language of the statute, as the .present case itself illustrates. United is liable under the statute only because it engaged in conduct that caused false claims to be submitted to the United States. While it is true that no false claims would have been submitted had United and Model not entered into a contractual relationship, the entry into that relationship did not in itself cause the submission of any false claims. Had United shipped tubes of the required quality to Model, no false claims would have been presented. By the same token, Model was not caused to file a false claim until it received shipments of falsely branded tubes from United. The language of the statute focuses on false claims, not on contracts. See n. 4, supra. That language does not support a conclusion that United is chargeable with only one forfeiture in this case.
To equate the number of forfeitures with the number of contracts would in a case such as this result almost always in but a single forfeiture, no matter how many fraudulent acts the subcontractor might have committed. This result would not only be at odds with the statutory language; it would also defeat the statutory purpose. Such a limitation would, in the language of the Government’s brief, convert “the Act’s forfeiture provision into little more than a $2,000 license for subcontractor fraud.”
At the other extreme, the Government urges that 35 forfeitures should be assessed, in accord with the position of the District Court, which ruled that “[United’s fraudulent] acts caused Model to submit thirty-five false claims, each of which constituted a separate violation justifying a separate forfeiture.” 361 F. Supp., at 879. The difficulty with this position is that it fails to distinguish between the acts committed by Model and the acts committed by United. The distinction is a critical one, because the statute imposes liability only for the commission of acts which cause false claims to be presented.
If United had committed one act which caused Model to file a false claim, it would clearly be liable for a single forfeiture. If, as a result of the same act by United, Model had filed three false claims, United would still have committed only one act that caused the filing of false claims, and thus, under the language of the statute, would again be liable for only one forfeiture. If, on the other hand, United had committed three separate such causative acts, United would be liable for three forfeitures, even if Model had filed only one false claim. The Act, in short, penalizes a person for his own acts, not for the acts of someone else.
The Government’s claim that United “caused” Model to submit 35 false claims is simply not accurate. While United committed certain acts which caused Model to submit false claims, it did not cause Model to submit any particular number of false claims. The fact that Model chose to submit 35 false claims instead of some other number was, so far as United was concerned, wholly irrelevant — completely fortuitous and beyond United’s knowledge or control. The Government suggests that United assumed the risk that Model might send 35 invoices when United sent the falsely branded tubes to Model. The statute, however, does not penalize United for what Model did. It penalizes United for what it did. The construction given to the statutory language by the District Court is, therefore, no more satisfactory than the interpretation adopted by the Court of Appeals.
A correct application of the statutory language requires, rather, that the focus in each case be upon the specific conduct of the person from whom the Government seeks to collect the statutory forfeitures. In the present case United committed three acts which caused Model to submit false claims to the Government — the three separately invoiced shipments to Model. If United had not shipped any falsely branded tubes to Model, Model could not have incorporated such tubes into its radio kits and would not have had occasion to submit any false claims to the United States. When, however, United dispatched each shipment of falsely marked tubes to Model, it did so knowing that Model would incorporate the tubes into the radio kits it later shipped to the Government, and that it would ask for payment from the Government on account of those tubes. Thus, United’s three shipments of falsely branded tubes to Model caused Model to submit false claims to the United States, and United is thus liable for three $2,000 statutory forfeitures representing the three separate shipments that it made to Model.
Ill
Computation of Double Damages
In the District Court “[I] be Government . . . established that the per unit cost to replace the [falsely branded] tubes was $40.82.” 361 F. Supp., at 875. Finding that the Government had already received $40.72 per tube as damages from Model, the court concluded, and the Court of Appeals agreed, that the Government’s total statutory damages were $79.40 — double the 10-cent difference per tube between its replacement costs and the payment already received from Model for the 397 tubes.
The Government argues that both courts were wrong, and that its damages under the Act should be calculated by doubling the amount of its original loss and only then deducting Model’s payment from that doubled amount. We agree that the Government’s damages should be doubled before any compensatory payments are deducted, because that method of computation most faithfully conforms to the language and purpose of the Act.
Although there is nothing in the legislative history that specifically bears on the question of how to calculate double damages, past decisions of this Court have reflected a clear understanding that Congress intended the double-damages provision to play an important role in compensating the United States in cases where it has been defrauded. “We think the chief purpose of the [Act’s civil penalties] was to provide for restitution to the government of money taken from it by fraud, and that the device of double damages plus a specific sum was chosen to make sure that the government would be made completely whole.” United States ex rel. Marcus v. Hess, 317 U. S., at 551-552. For several different reasons, this make-whole purpose of the Act is best served by doubling the Government’s damages before any compensatory payments are deducted.
First, this method of computation comports with the congressional judgment that double damages are necessary to compensate the Government completely for the costs, delays, and inconveniences occasioned by fraudulent claims. Second, the rule that damages should be doubled prior to any deductions fixes the liability of the defrauder without reference to the adventitious actions of other persons. The position adopted by the Court of Appeals would mean that two subcontractors who committed similar acts and caused similar damage could be subjected to widely disparate penalties depending upon whether and to what extent their prime contractors had paid the Government in settlement of the Government’s claims against them. Just as fortuitous acts of the prime contractor should not determine the liability of the subcontractor under the forfeiture provision of the Act, so likewise the prime contractor’s fortuitous acts should not determine the liability of the subcontractor under the double-damages provision. Third, the reasoning of the Court of Appeals and the District Court would enable the subcontractor to avoid the Act’s double-damages provision by tendering the amount of the undoubled damages at any time prior to judgment. This possibility would make the double-damages provision meaningless. Doubling the Government’s actual damages before any deduction is made for payments previously received from any source in mitigation of those damages forecloses such a result.
For these reasons we hold that, in computing the double damages authorized by the Act, the Government’s actual damages are to be doubled before any subtractions are made for compensatory payments previously received by the Government from any source. This method of computation, which maximizes the deterrent impact of the double-damages provision and fixes the relative rights and liabilities of the respective parties with maximum precision, best comports in our view with the language and purpose of the Act.
The judgment is reversed, and the case is remanded to the Court of Appeals for further proceedings consistent with this opinion.
It is so ordered.
Me. Justice Stevens took no part in the consideration or decision of this case.
The False Claims Act was adopted in 1863. Act of Mar. 2, Í863, c. 67, 12 Stat. 696. It was re-enacted as Rev. Stat. §§ 3490-3494, 5438. The part of the Act dealing with civil prohibitions is now codified in 31 U. S. C. § 231 et seq. The language used in Title 31 differs in some important respects from that contained in the Revised Statutes. Since Title 31 has not been enacted into positive law, the official text of the statute is that which appears in the Revised Statutes. See United States v. Neifert-White Co., 390 U. S. 228, 228-229, n. 1; United States ex rel. Marcus v. Hess, 317 U. S. 537, 539-540, and n. 2.
The relevant statutory provisions are as follows:
§ 3490. “Any person not in the military or naval forces of the United States, or in the militia called into or actually employed in the service of the United States, who shall do or commit any of the acts prohibited by any of the provisions of section fifty-four hundred and thirty-eight, Title 'CRIMES/ shall forfeit and pay to the United States the sum of two thousand dollars, and, in addition, double the amount of damages which the United States may have sustained by reason of the doing or committing such act, together with the costs of suit; and such forfeiture and damages shall be sued for in the same suit.”
§ 5438. “Every person who makes or causes to be made, or presents or causes to be presented, for payment or approval, to or by any person or officer in the civil, military, or naval service of the United States, any claim upon or against the Government of the United States, or any department or officer thereof, knowing such claim, to be false, fictitious, or fraudulent, or who, for the purpose of obtaining or aiding to obtain the payment or approval of such claim, makes, uses, or causes to be made or used, any false bill, receipt, voucher, roll, account, claim, certificate, affidavit, or deposition, knowing the same to contain any fraudulent or fictitious statement or entry, or who enters into any agreement, combination, or conspiracy to defraud the Government of the United States, or any department or officer thereof, by obtaining or aiding to obtain the payment or allowance of any false or fraudulent claim, or who, having charge, possession, custody, or control of any money or other public property used or to be used in the military or naval service, who, with intent to defraud the United States or willfully .to conceal such money or other property, delivers or causes to be delivered, to any other person having authority to receive the same, any amount of such money or other property less than that for which he received a certificate or took a receipt, and every person authorized to make or deliver any certificate, voucher, receipt, or other paper certifying the receipt of arms, ammunition, provisions, clothing, or other property so used or to be used, who makes or delivers the same to any other person without a full knowledge of the truth of the facts stated therein, and with intent to defraud the United States, and every person who knowingly purchases or receives in pledge for any obligation or indebtedness from any soldier, officer, sailor, or other person called into or employed in the military or naval service any arms, equipments, ammunition, clothes, military stores, or other public property, such soldier, sailor, officer, or other person not having the lawful right to pledge or sell the same, every person so offending in any of the matters set forth in this section shall be imprisoned at hard labor for not less than one nor more than five years, or fined not less than one thousand nor more than five thousand dollars.”
Section 5438 was repealed in 1909. Act of Mar. 4, 1909, c. 321, § 341, 35 Stat. 1153. It has continued vitality only insofar as it specifies the acts giving rise to civil liability under § 3490. See United States v. Neifert-White Co., supra. The criminal prohibitions were subsequently altered and codified in 18 U. S. C. §§287 and 1001.
United was dismissed as a party prior to judgment. For convenience, however, the respondents are sometimes referred to in this opinion as United. The United States also brought criminal charges against Bornstein and Page. They pleaded guilty to those charges and were given suspended sentences.
The Government also claimed that United was liable for three additional $2,000 forfeitures under the second clause of § 5438 which prohibits the preparation and use of false documents in support of a false claim. See n. 1, supra. The Government does not press that claim here.
In cases involving prime contractors the number of imposable forfeitures has generally been set at the number of individual false payment demands that the contractor has made upon the Government. See, e. g., United States v. Woodbury, 359 F. 2d 370, 377-378 (CA9); Fleming v. United States, 336 F. 2d 475, 480 (CA10); United States v. National Wholesalers, 236 F. 2d 944, 950 (CA9); Faulk v. United States, 198 F. 2d 169, 171 (CA5); United States v. Grannis, 172 F. 2d 507, 515-516 (CA4); United States v. Collyer Insulated Wire Co., 94 F. Supp. 493, 496-498 (RI). Cf. United States v. Ueber, 299 F. 2d 310 (CA6). This result is in accord with this Court’s statement that “ ‘the conception of a claim against the government normally connotes a demand for money or for some transfer of public property.’” United States v. McNinch, 356 U. S. 595, 599, quoting United States v. Tieger, 234 F. 2d 589, 591 (CA3).
According to its sponsor, the False Claims Act was adopted “for the purpose of punishing and preventing . . . frauds.” Cong. Globe, 37th Cong., 3d Sess., 952 (remarks of Sen. Howard). See also id., at 955 (remarks of Sen. Wilson).
See n. 5, supra.
Cf. United States v. Ueber, 299 F. 2d 310 (CA6).
This Court has noted that in construing § 5438 “we are actually construing the provisions of a criminal statute. Such provisions must be carefully restricted, not only to their literal terms but to the evident purpose of Congress in using those terms, particularly where they are broad and susceptible [of] numerous definitions.” United States v. McNinch, 356 U. S., at 598. See also Rainwater v. United States, 356 U. S. 590, 592-593.
At one point in this litigation the Government urged that any compensatory payments it received should not be deducted from its statutory damages at all. It has now abandoned that position, perhaps for the reason that since United is liable to Model for Model’s payment to the United States, United would in effect be assessed triple damages under such a rule.
The statute speaks of doubling “damages” and not doubling “net damages” or “uncompensated damages.”
As originally enacted, the False Claims Act contained a qui tarn provision which authorized any person to bring an action on behalf of the United States to recover the civil penalties that could be imposed under the Act. Act of Mar. 2, 1863, §4, 12 Stat. 698. If successful, the person would receive one-half of the damages awarded to the United States. § 6. Respondents suggest that double damages were provided by Congress because it knew that half of the Government’s recovery would go to a private person and that as a result double damages were necessary in order to allow the Government’s share of the proceeds of a suit to cover the Government’s single damages. Thus, they argue that Congress never concluded that the United States needed to recover double damages in order to be made completely whole.
This argument would have some force if the only enforcement mechanism provided in the Act were the qui tarn action. However, the Act clearly envisioned that the Government could sue on its own behalf, §4, and it specifically exhorted United States attorneys to enforce the Act diligently. § 5. Moreover, in 1943 Congress placed restrictions on the possibility of bringing a qui tarn action and limited a private person’s recovery to a maximum of one quarter of the damages awarded the United States, Act of Dee. 23, 1943, c. 377, 57 Stat. 608. In adopting these changes, Congress did not make any adjustment in the double-damages provision, again suggesting that it thought that double damages are necessary to make the United States whole in fraudulent-claim cases.
The only two District Courts that have addressed this question have reached opposing results. Compare United States v. Klein, 230 F. Supp. 426, 443 (WD Pa.), aff’d per curiam, 356 F. 2d 983 (CA3) (damages doubled after offsetting credits deducted), with United States v. Globe Remodeling Co., 196 F. Supp. 652, 657 (Vt.) (damages doubled before offsetting credits deducted).
The Government's actual damages are equal to the difference between the market value of the tubes it received and retained and the market value that the tubes would have had if they had been of the specified quality. C. McCormick, Law of Damages § 42, p. 137 (1935). See, e. g., United States v. Cooperative Grain & Supply Co., 476 F. 2d 47, 61-65 (CA8); United States v. Foster Wheeler Corp., 447 F. 2d 100, 102 (CA2); United States v. Woodbury, 359 F. 2d, at 379; Toepleman v. United States, 263 F. 2d 697, 700 (CA4); United States v. Ben Grunstein & Sons Co., 137 F. Supp. 197, 205 (NJ); United States v. American Packing Corp., 125 F. Supp. 788, 791 (NJ); but cf. United States v. Aerodex, Inc., 469 F. 2d 1003, 1010-1011 (CA5); Faulk v. United States, 198 F. 2d 169, 172 (CA5).
