[207]*207Mr. Justice Stewart
delivered the opinion of the Court.
The respondents, 18 owners of independent pharmacies in San Antonio, Tex., brought an antitrust action in a Federal District Court against the petitioners, Group Life and Health Insurance Co., known as Blue Shield of Texas (Blue Shield), and three pharmacies also doing business in San Antonio. The complaint alleged that the petitioners had violated § 1 of the Sherman Act, 15 U. S. C. § 1, by entering agreements to fix the retail prices of drugs and pharmaceuticals, and that the activities of the petitioners had caused Blue Shield’s policyholders not to deal with certain of the respondents, thereby constituting an unlawful group boycott. The trial court granted summary judgment to the petitioners on the ground that the challenged agreements are exempt from the antitrust laws under § 2 (b) of the McCarran-Ferguson Act, 59 Stat. 34, as amended, 61 Stat. 448, 15 U. S. C. § 1012 (b), because the agreements are the “business of insurance,” are “regulated by [Texas] law,” and are not “boycotts” within the meaning of § 3 (b) of the Act, 59 Stat. 34, 15 U. S. C. [208]*208§ 1013(b).1 415 F. Supp. 343 (WD Tex.). The Court of Appeals for the Fifth Circuit reversed the judgment. Holding that the agreements in question are not the “business of insurance” within the meaning of §2 (b), the appellate court did not reach the other questions decided by the trial court. 556 F. 2d 1375. We granted certiorari because of intercircuit conflicts as to the meaning of the phrase “business of insurance” in § 2 (b) of the Act.2 435 U. S. 903.

Blue Shield offers insurance policies which entitle the policyholders to obtain prescription drugs. If the pharmacy selected by the insured has entered into a “Pharmacy Agreement” with Blue Shield, and is therefore a participating pharmacy, the insured is required to pay only $2 for every prescription drug. The remainder of the cost is paid directly by Blue Shield to the participating pharmacy. If, on the other hand, the insured selects a pharmacy which has not entered into a Pharmacy Agreement, and is therefore a nonparticipating pharmacy, he is required to pay the full price charged by the pharmacy. The insured may then obtain reimbursement from Blue Shield for 75% of the difference between that price and $2.
Blue Shield offered to enter into a Pharmacy Agreement with each licensed pharmacy in Texas. Under the Agreement, a participating pharmacy agrees to furnish prescription drugs to Blue Shield’s policyholders at $2 for each prescription, and Blue Shield agrees to reimburse the pharmacy for the pharmacy’s cost of acquiring the amount of the drug prescribed. Thus, only pharmacies that can afford to distribute prescription drugs for less than this $2 markup can profitably participate in the plan.3
[210]*210The only issue before us is whether the Court of Appeals was correct in concluding that these Pharmacy Agreements are not the “business of insurance” within the meaning of § 2 (b) of the McCarran-Ferguson Act. If that conclusion is correct, then the Agreements are not exempt from examination under the antitrust laws.4 Whether the Agreements are illegal under the antitrust laws is an entirely separate question, not now before us.5

As the Court stated last Term in St. Paul Fire & Marine Ins. Co. v. Barry, 438 U. S. 531, 541,6 the starting point in a case involving construction of the McCarran-Ferguson Act, like the starting point in any case involving the meaning of a statute, is the language of the statute itself. See also Blue Chip Stamps v. Manor Drug Stores, 421 U. S. 723, 756 (Powell, J., concurring). It is important, therefore, to observe at the outset that the statutory language in question [211]*211here does not exempt the business of insurance companies from the scope of the antitrust laws. The exemption is for the “business of insurance,” not the “business of insurers”:
“The statute did not purport to make the States supreme in regulating all the activities of insurance companies; its language refers not to the persons or companies who are subject to state regulation, but to laws 'regulating the business of insurance.’ Insurance companies may do many things which are subject to paramount federal regulation; only when they are engaged in the ‘business of insurance’ does the statute apply.” SEC v. National Securities, Inc., 393 U. S. 453, 459-460. (Emphasis in original.)
Since the law does not define the “business of insurance,” the question for decision is whether the Pharmacy Agreements fall within the ordinary understanding of that phrase, illumined by any light to be found in the structure of the Act and its legislative history. Cf. Ernst & Ernst v. Hochfelder, 425 U.S. 185,199, and n. 19.

The primary elements of an insurance contract are the spreading and underwriting of a policyholder’s risk. “It is characteristic of insurance that a number of risks are accepted, some of which involve losses, and that such losses are spread over all the risks so as to enable the insurer to accept each risk at a slight fraction of the possible liability upon it.” 1 G. Couch, Cyclopedia of Insurance Law § 1:3 (2d ed. 1959). See also R. Keeton, Insurance Law § 1.2 (a) (1971) (“Insurance is an arrangement for transferring and distributing risk”); 1 G. Richards, The Law of Insurance § 2 (W. Freedman 5th ed. 1952).7
[212]*212The significance of underwriting or spreading of risk as an indispensable characteristic of insurance was recognized by this Court in SEC v. Variable Annuity Lije Ins, Co., 359 U. S. 65. That case involved several corporations, representing themselves as “life insurance” companies, that offered variable annuity contracts for sale in interstate commerce. The companies were regulated by the insurance commissioners of several States. Purchasers of the contracts were not entitled to any fixed return, but only to a pro rata participation in the investment portfolios of the companies. Thus a policyholder could receive substantial sums if investment decisions were successful, but very little if they were not. One of the questions presented was whether these variable annuity contracts were the “business of insurance” under § 2 (b) of the McCarran-Ferguson Act.8 The Court held that the annuity contracts were not insurance, even though they were regulated as such under state law and involved actuarial prognostications of mortality. Central to the Court's holding was the premise that “the concept of 'insurance' involves some investment risk-taking on the part of the company.” 359 U. S., at 71.

delivered the opinion of the Court.
The respondents, 18 owners of independent pharmacies in San Antonio, Tex., brought an antitrust action in a Federal District Court against the petitioners, Group Life and Health Insurance Co., known as Blue Shield of Texas (Blue Shield), and three pharmacies also doing business in San Antonio. The complaint alleged that the petitioners had violated § 1 of the Sherman Act, 15 U. S. C. § 1, by entering agreements to fix the retail prices of drugs and pharmaceuticals, and that the activities of the petitioners had caused Blue Shield’s policyholders not to deal with certain of the respondents, thereby constituting an unlawful group boycott. The trial court granted summary judgment to the petitioners on the ground that the challenged agreements are exempt from the antitrust laws under § 2 (b) of the McCarran-Ferguson Act, 59 Stat. 34, as amended, 61 Stat. 448, 15 U. S. C. § 1012 (b), because the agreements are the “business of insurance,” are “regulated by [Texas] law,” and are not “boycotts” within the meaning of § 3 (b) of the Act, 59 Stat. 34, 15 U. S. C. [208]*208§ 1013(b).1 415 F. Supp. 343 (WD Tex.). The Court of Appeals for the Fifth Circuit reversed the judgment. Holding that the agreements in question are not the “business of insurance” within the meaning of §2 (b), the appellate court did not reach the other questions decided by the trial court. 556 F. 2d 1375.

Blue Shield offers insurance policies which entitle the policyholders to obtain prescription drugs. If the pharmacy selected by the insured has entered into a “Pharmacy Agreement” with Blue Shield, and is therefore a participating pharmacy, the insured is required to pay only $2 for every prescription drug. The remainder of the cost is paid directly by Blue Shield to the participating pharmacy. If, on the other hand, the insured selects a pharmacy which has not entered into a Pharmacy Agreement, and is therefore a nonparticipating pharmacy, he is required to pay the full price charged by the pharmacy. The insured may then obtain reimbursement from Blue Shield for 75% of the difference between that price and $2.
Blue Shield offered to enter into a Pharmacy Agreement with each licensed pharmacy in Texas. Under the Agreement, a participating pharmacy agrees to furnish prescription drugs to Blue Shield’s policyholders at $2 for each prescription, and Blue Shield agrees to reimburse the pharmacy for the pharmacy’s cost of acquiring the amount of the drug prescribed. Thus, only pharmacies that can afford to distribute prescription drugs for less than this $2 markup can profitably participate in the plan.3
[210]*210The only issue before us is whether the Court of Appeals was correct in concluding that these Pharmacy Agreements are not the “business of insurance” within the meaning of § 2 (b) of the McCarran-Ferguson Act. If that conclusion is correct, then the Agreements are not exempt from examination under the antitrust laws.4 Whether the Agreements are illegal under the antitrust laws is an entirely separate question, not now before us.5

As the Court stated last Term in St. Paul Fire & Marine Ins. Co. v. Barry, 438 U. S. 531, 541,6 the starting point in a case involving construction of the McCarran-Ferguson Act, like the starting point in any case involving the meaning of a statute, is the language of the statute itself. See also Blue Chip Stamps v. Manor Drug Stores, 421 U. S. 723, 756 (Powell, J., concurring). It is important, therefore, to observe at the outset that the statutory language in question [211]*211here does not exempt the business of insurance companies from the scope of the antitrust laws. The exemption is for the “business of insurance,” not the “business of insurers”:
“The statute did not purport to make the States supreme in regulating all the activities of insurance companies; its language refers not to the persons or companies who are subject to state regulation, but to laws 'regulating the business of insurance.’ Insurance companies may do many things which are subject to paramount federal regulation; only when they are engaged in the ‘business of insurance’ does the statute apply.” SEC v. National Securities, Inc., 393 U. S. 453, 459-460. (Emphasis in original.)
Since the law does not define the “business of insurance,” the question for decision is whether the Pharmacy Agreements fall within the ordinary understanding of that phrase, illumined by any light to be found in the structure of the Act and its legislative history. Cf. Ernst & Ernst v. Hochfelder, 425 U.S. 185,199, and n. 19.

The primary elements of an insurance contract are the spreading and underwriting of a policyholder’s risk. “It is characteristic of insurance that a number of risks are accepted, some of which involve losses, and that such losses are spread over all the risks so as to enable the insurer to accept each risk at a slight fraction of the possible liability upon it.” 1 G. Couch, Cyclopedia of Insurance Law § 1:3 (2d ed. 1959). See also R. Keeton, Insurance Law § 1.2 (a) (1971) (“Insurance is an arrangement for transferring and distributing risk”); 1 G. Richards, The Law of Insurance § 2 (W. Freedman 5th ed. 1952).7
[212]*212The significance of underwriting or spreading of risk as an indispensable characteristic of insurance was recognized by this Court in SEC v. Variable Annuity Lije Ins, Co., 359 U. S. 65. That case involved several corporations, representing themselves as “life insurance” companies, that offered variable annuity contracts for sale in interstate commerce. The companies were regulated by the insurance commissioners of several States. Purchasers of the contracts were not entitled to any fixed return, but only to a pro rata participation in the investment portfolios of the companies. Thus a policyholder could receive substantial sums if investment decisions were successful, but very little if they were not. One of the questions presented was whether these variable annuity contracts were the “business of insurance” under § 2 (b) of the McCarran-Ferguson Act.8 The Court held that the annuity contracts were not insurance, even though they were regulated as such under state law and involved actuarial prognostications of mortality. Central to the Court's holding was the premise that “the concept of 'insurance' involves some investment risk-taking on the part of the company.” 359 U. S., at 71. Since the variable annuity contracts offered no guarantee of fixed income, they placed all the investment risk on the annuitant and none on the company. Ibid. The Court concluded, therefore, that the annuities involved “no true underwriting of risks, the one earmark of insurance as it has commonly been conceived of in popular understanding and usage.” Id., at 73 (footnote omitted). Cf. German Alliance Ins, Co. v. Lewis, 233 U. S. 389, 412 (“The effect of insurance — indeed [213]*213it has been said to be its fundamental object — is to distribute the loss over as wide an area as possible”).
The petitioners do not really dispute that the underwriting or spreading of risk is a critical determinant in identifying insurance. Rather they argue that the Pharmacy Agreements do involve the underwriting of risks. As they state in their brief:
“In Securities and Exchange Commission v. Variable Annuity Lije Insurance Co., 359 U. S. 65, 73 (1959), the 'earmark’ of insurance was described as the 'underwriting of risks’ in exchange for a premium. Here the risk insured against is the possibility that, during the term of the policy, the insured may suffer a financial loss arising from the purchase of prescription drugs, or that he may be financially unable to purchase such drugs. In consideration of the premium, Blue Shield assumes this risk by agreeing with its insureds to contract with Participating Pharmacies to furnish the needed drugs and to reimburse the Pharmacies for each prescription filled for the insured. In short, each of the fundamental elements of insurance is present here — the payment of a premium in exchange for a promise to indemnify the insured against losses upon the happening of a specified contingency.”
The fallacy of the petitioners’ position is that they confuse the obligations of Blue Shield under its insurance policies, which insure against the risk that policyholders will be unable to pay for prescription drugs during the period of coverage, and the agreements between Blue Shield and the participating pharmacies, which serve only to minimize the costs Blue Shield incurs in fulfilling its underwriting obligations.9 The [214]*214benefit promised to Blue Shield policyholders is that their premiums will cover the cost of prescription drugs except for a $2 charge for each prescription.10 So long as that promise is kept, policyholders are basically unconcerned with arrangements made between Blue Shield and participating pharmacies.11
The Pharmacy Agreements thus do not involve any underwriting or spreading of risk, but are merely arrangements for the purchase of goods and services by Blue Shield. By agreeing with pharmacies on the maximum prices it will pay for drugs, Blue Shield effectively reduces the total amount it must pay to its policyholders. The Agreements thus enable Blue Shield to minimize costs and maximize profits. Such cost-savings arrangements may well be sound business practice, and may well inure ultimately to the benefit of policyholders in the form of lower premiums, but they are not the “business of insurance.”12
[215]*215The Pharmacy Agreements are thus legally indistinguishable from countless other business arrangements that may be made by insurance companies to keep their costs low and thereby also keep low the level of premiums charged to their policyholders. Suppose, for example, that an insurance company entered into a contract with a large retail drug chain whereby its policyholders could obtain drugs under their policies only from stores operated by this chain. The justification for such an agreement would be administrative and bulk-purchase savings resulting from obtaining all of the company's drug needs from a single dealer. Even though these cost savings might ultimately be reflected in lower premiums to policyholders, would such a contract be the “business of insurance”? Or suppose that the insurance company should decide to acquire the chain of drug stores in order to lower still further its costs of meeting its obligations to its policyholders. Such an acquisition would surely not be the “business of insurance.” SEC v. National Securities, Inc., 393 U. S. 453.13
C
Another commonly understood aspect of the business of insurance relates to the contract between the insurer and the insured. In enacting the McCarran-Ferguson Act Congress was concerned with:
“The relationship between insurer and insured, the type of policy which could be issued, its reliability, interpreta[216]*216tion, and enforcement — these were the core of the ‘business of insurance.’ Undoubtedly, other activities of insurance companies relate so closely to their status as reliable insurers that they too must be placed in the same class. But whatever the exact scope of the statutory term, it is clear where the focus was — it was on the relationship between the insurance company and the policyholder.” SEC v. National Securities, Inc., supra, at 460.
The Pharmacy Agreements are not “between insurer and insured.” They are separate contractual arrangements between Blue Shield and pharmacies engaged in the sale and distribution of goods and services other than insurance.
The petitioners argue that nonetheless the Pharmacy Agreements so closely affect the “reliability, interpretation, and enforcement” of the insurance contract and “relate so closely to their status as reliable insurers” as to fall within the exempted area.14 This argument, however, proves too much.
At the most, the petitioners have demonstrated that the Pharmacy Agreements result in cost savings to Blue Shield which may be reflected in lower premiums if the cost savings are passed on to policyholders. But, in that sense, every business decision made by an insurance company has some impact on its reliability, its ratemaking, and its status as a [217]*217reliable insurer. The manager of an insurance company is no different from the manager of any enterprise with the responsibility to minimize costs and maximize profits. If terms such as “reliability” and “status as a reliable insurer” were to be interpreted in the broad sense urged by the petitioners, almost every business decision of an insurance company could be included in the “business of insurance.” Such a result would be plainly contrary to the statutory language, which exempts the “business of insurance” and not the “business of insurance companies.”
Ill
The conclusion that the Pharmacy Agreements are not the “business of insurance” is fully confirmed by the legislative history of the McCarran-Ferguson Act. The law was enacted in 1945 in response to this Court’s decision in United States v. South-Eastern Underwriters Assn., 322 U. S. 533. The indictment in that case charged that the defendants had conspired to fix insurance rates and commissions, and had conspired to boycott and coerce noncooperating insurers, agents, and insureds. In the District Court the defendants had successfully demurred to the indictment on the ground that the insurance industry was not a part of interstate commerce subject to regulation under the Commerce Clause.15 On direct appeal, this Court reversed the judgment, holding that the business of insurance is interstate commerce, and that the Congress which enacted the Sherman Act had not intended to exempt the insurance industry from its coverage.
The primary concern of Congress in the wake of that decision was in enacting legislation that would ensure that [218]*218the States would continue to have the ability to tax and regulate the business of insurance.16 This concern is reflected in §§ 1 and 2 (a) of the Act,17 neither of which is involved in this case. A secondary concern was the applicability of the antitrust laws to the insurance industry.18 Months before [219]*219this Court’s decision in South-Eastern Underwriters was announced, proposed legislation to totally exempt the insurance industry from the Sherman and Clayton Acts had been introduced in Congress.19 Less than three weeks after the actual decision, the House of Representatives passed a bill which would also have provided the insurance industry with a blanket exemption from the antitrust laws, thus restoring the state of law that had existed before the decision in SouthEastern Underwriters.20
Congress, however, rejected this approach.21 Instead of a total exemption, Congress provided in § 2 (b) that the antitrust laws “shall be applicable” unless the activities of insurance companies are the business of insurance and regulated by state law. Moreover, under § 3 (b) the Sherman Act was made applicable in any event to acts of boycott, coercion, or intimidation. To allow the States time to adjust to the applicability of the antitrust laws to the insurance industry, [220]*220Congress imposed a 3-year moratorium.22 After the expiration of the moratorium on July 1, 1948, however, Congress clearly provided that the antitrust laws would be applicable to the business of insurance “to the extent that such business is not regulated by State law.” 23
By making the antitrust laws applicable to the insurance industry except as to conduct that is the business of insurance, regulated by state law, and not a boycott, Congress did not intend to and did not overrule the South-Eastern Underwriters case.24 While the power of the States to tax and regulate insurance companies was reaffirmed, the McCarran-Ferguson Act also established that the insurance industry would no longer have a blanket exemption from the antitrust laws. It is true that § 2 (b) of the Act does create a partial exemption from those laws. Perhaps more significantly, however, that section, and the Act as a whole, embody a legislative rejection of the concept that the insurance industry is outside the scope of the antitrust laws — a concept that had prevailed before the South-Eastern Underwriters decision.
References to the meaning of the “business of insurance” in the legislative history of the McCarran-Ferguson Act [221]*221strongly suggest that Congress understood the business of insurance to be the underwriting and spreading of risk. Thus, one of the early House Reports stated: “The theory of insurance is the distribution of risk according to hazard, experience, and the laws of averages. These factors are not within the control of insuring companies in the sense that the producer or manufacturer may control cost factors.” H. R. Rep. No. 873, 78th Cong., 1st Sess., 8-9 (1943).25 See also S. Rep. No. 1112, 78th Cong., 2d Sess., 6 (1944); 90 Cong. Rec. 6526 (1944) (remarks of Rep. Hancock).
Because of the widespread view that it is very difficult to underwrite risks in an informed and responsible way without intra-industry cooperation, the primary concern of both representatives of the insurance industry and the Congress was that cooperative ratemaking efforts be exempt from the antitrust laws. The passage of the McCarran-Ferguson Act was preceded by the introduction in the Senate Committee of a report and a bill submitted by the National Association of Insurance Commissioners on November 16, 1944.26 The views of the NAIC are particularly significant, because the Act ultimately passed was based in large part on the NAIC bill.27 The report emphasized that the concern of the insurance commissioners was that smaller enterprises and insurers other than life insurance companies were unable to underwrite risks accurately, and it therefore concluded:
“For these and other reasons this subcommittee believes it would be a mistake to permit or require the unrestricted competition contemplated by the antitrust laws to apply to the insurance business. To prohibit oom-[222]*222bined efforts for statistical and rate-making purposes would be a backward step in the development of a progressive business. We do not regard it as necessary to labor this point any further because Congress itself recently recognized the necessity for concert of action in the collection of statistical data and rate making when it enacted the District of Columbia Fire Insurance Rating Act.” Id., at A4405 (emphasis added).
The bill proposed by the NAIC enumerated seven specific practices to which the Sherman Act was not to apply.28 Each of the specific practices involved intra-industry cooperative or concerted activities. None involved contractual arrangements that insurance companies might make with providers of goods or services to reduce the costs to the companies of meeting their underwriting obligations to their policyholders.29
[223]*223The floor debates also focused simply on whether cooperative ratemaking should be exempt. Thus, Senator Ferguson, in explaining the purpose of the bill, stated:
“This bill would permit — and I think it is fair to say that it is intended to permit — rating bureaus, because in the last session we passed a bill for the District of Columbia allowing rating. What we saw as wrong was the fixing of rates without statutory authority in the States; but we believe that State rights should permit a State to say that it believes in a rating bureau. I think the insurance companies have convinced many members of the legislature that we cannot have open competition in fixing rates on insurance. If we do, we shall have chaos. There will be failures, and failures always follow losses.” 91 Cong. Rec. 1481 (1945).
The consistent theme of the remarks of other Senators also indicated a primary concern that cooperative ratemaking would be protected from the antitrust laws. Id., at 1444 and 1485 (remarks of Sen. O’Mahoney); 485 (remarks of Sen. Taft).30 President Roosevelt, in signing the bill, also em[224]*224phasized that the bill would allow cooperative rate regulation. He stated that “Congress did not intend to permit private rate fixing, which the Antitrust Act forbids, but was willing to permit actual regulation of rates by affirmative action of the States.” S. Rosenman, The Public Papers and Addresses of Franklin D. Roosevelt, 1944-1945 Vol., p. 587 (1950).31 There is not the slightest suggestion in the legislative history that Congress in any way contemplated that arrangements such as the Pharmacy Agreements in this case, which involve the mass purchase of goods and services from entities outside the insurance industry, are the “business of insurance.” 32
[225]*225D
At the time of the enactment of the McCarran-Ferguson Act, corporations organized for the purpose of providing their [226]*226members with medical services and hospitalization were not considered to be engaged in the insurance business at all, and thus were not subject to state insurance laws. E. g., Jordan v. Group Health Assn., 71 App. D. C. 38, 107 F. 2d 239 (1939); California Physicians’ Service v. Garrison, 155 P. 2d 885 (Cal. App. 1945). affd, 28 Cal. 2d 790, 172 P. 2d 4 (1946); Commissioner of Banking & Insurance v. Community Health Service, 129 N. J. L. 427, 30 A. 2d 44 (1943); State ex rel. Fishback v. Universal Service Agency, 87 Wash. 413, 151 P. 768 (1915).33 Similarly, States which regulated prepaid health-service plans at the time the Act was enacted either exempted them from the requirements of the state insurance code or provided that they “shall not be construed as being engaged in the business of insurance” under state law. Rorem, Enabling Legislation for Non-Profit Hospital Service Plans, 6 Law & Contemp. Prob. 528, 534 (1939).34 Since the legisla[227]*227tive history makes clear that Congress certainly did not intend the definition of the “business of insurance” to be broader than its commonly understood meaning, the contemporary perception that health-care organizations were not engaged in providing insurance is highly significant in ascertaining congressional intent.
The Jordan v. Group Health hLssn. case, supra, is illustrative of the contemporary view of health-care plans. Group Health was organized as a nonprofit corporation to provide various medical services and supplies to members who paid a fixed annual premium. To implement the plan, Group Health contracted with physicians, hospitals, and others, to provide medical services. These groups were compensated exclusively by Group Health. By contracting with the various medical groups directly, Group Health was able to obtain [228]*228services at a lower cost than if each member contracted separately. The plan, therefore, was somewhat similar to the Pharmacy Agreements in this case. The court in Group Health held that this type of arrangement was not insurance:
“Whether the contract is one of insurance or of indemnity there must be a risk of loss to which one party may be subjected by contingent or future events and an assumption of it by legally binding arrangement by another. Even the most loosely stated conceptions of insurance . . . require these elements. Hazard is essential and equally so a shifting of its incidence.
“Although Group Health’s activities may be considered in one aspect as creating security against loss from illness or accident, more truly they constitute the quantity purchase of well-rounded, continuous medical service by its members. Group Health is in fact and in function a consumer cooperative. The functions of such an organization are not identical with those of insurance or indemnity companies. The latter are concerned primarily, if not exclusively, with risk .... On the other hand, the cooperative is concerned principally with getting service rendered to its members and doing so at lower prices made possible by quantity purchasing and economies in operation.” 71 App. D. C., at 44, 46, 107 F. 2d, at 245, 247. (Emphasis supplied in part; footnotes omitted.) 35
[229]*229Indeed, Blue Cross and Blue Shield organizations themselves have historically taken the position that they are not insurance companies in seeking to avoid state regulation and taxation.36 It is thus difficult to assume that contrary to this historical position and a majority of court decisions, Congress in 1945 understood that advance-payment medical-[230]*230benefits plans are the “business of insurance.” 37 It is next to impossible to assume that Congress could have thought that agreements (even by insurance companies) which provide for the purchase of goods and services from third parties at a set price are within the meaning of that phrase.38
[231]*231IV
It is well settled that exemptions from the antitrust laws are to be narrowly construed. E. g., Abbott Laboratories v. Portland Retail Druggists Assn., Inc., 425 U. S. 1; Connell Construction Co. v. Plumbers Steamfitters, 421 U. S. 616; FMC v. Seatrain Lines, Inc., 411 U. S. 726; United States v. McKesson & Robbins, Inc., 351 U. S. 305. This doctrine is not limited to implicit exemptions from the antitrust laws, but applies with equal force to express statutory exemptions. E. g., Abbott Laboratories v. Portland Retail Druggists Assn., Inc., supra, at 11-12 (the Nonprofit Institutions Act); FMC v. Seatrain Lines, Inc., supra, at 733 (§15 of the Shipping Act); United States v. McKesson Robbins, supra,'at 316 (the Miller-Tydings and McGuire Acts).
Application of this principle is particularly appropriate in this case because the Pharmacy Agreements involve parties wholly outside the insurance industry. In analogous contexts, the Court has held that an exempt entity forfeits antitrust exemption by acting in concert with nonexempt parties. The Court has held, for example, that an exempt agricultural cooperative under the Capper-Yolstead Act loses its exemption if it conspires with nonexempt parties. Case-Swayne Co. v. Sunkist Growers, Inc., 389 U. S. 384; United States v. Borden Co., 308 U. S. 188. Similarly, the Court has consistently stated that a union forfeits its exemption from the antitrust laws if it agrees with one set of employers to impose a wage scale on other bargaining units. Ramsey v. Mine Workers, [232]*232401 U. S. 302, 313; Mine Workers v. Pennington, 381 U. S. 657, 665-666.39
If agreements between an insurer and retail pharmacists are the “business of insurance” because they reduce the insurer’s costs, then so are all other agreements insurers may make to keep their costs under control — whether with automobile body repair shops or landlords.40 Such agreements [233]*233would be exempt from the antitrust laws if Congress had extended the coverage of the McCarran-Ferguson Act to the "business of insurance companies.”41 But that is precisely what Congress did not do.
For all these reasons, the judgment of the Court of Appeals is
Affirmed.
