Justice O'CONNOR delivered the opinion of the Court.This case calls upon the Court to decide whether the Employee Retirement Income Security Act of 1974 (ERISA), 88 Stat. 829, as amended, 29 U.S.C. § 1001 et seq., preempts a Pennsylvania law precluding employee welfare benefit plans from exercising subrogation rights on a claimant's tort recovery.IPetitioner, FMC Corporation (FMC), operates the FMC Salaried Health Care Plan (Plan), an employee welfare benefit plan within the meaning of ERISA, § 3(1), 29 U.S.C. § 1002(1), that provides health benefits to FMC employees and their dependents.  The Plan is self-funded; it does not purchase an insurance policy from any insurance company in order to satisfy its obligations to its participants.  Among its provisions is a subrogation clause under which a Plan member agrees to reimburse the Plan for benefits paid if the member recovers on a claim in a liability action against a third party.Respondent, Cynthia Ann Holliday, is the daughter of FMC employee and Plan member Gerald Holliday.  In 1987, Page 498 U. S. 55 she was seriously injured in an automobile accident.  The Plan paid a portion of her medical expenses.  Gerald Holliday brought a negligence action on behalf of his daughter in Pennsylvania state court against the driver of the automobile in which she was injured.  The parties settled the claim.  While the action was pending, FMC notified the Hollidays that it would seek reimbursement for the amounts it had paid for respondent's medical expenses.  The Hollidays replied that they would not reimburse the Plan, asserting that § 1720 of Pennsylvania's Motor Vehicle Financial Responsibility Law, 75 Pa.Cons.Stat. § 1720 (1987), precludes subrogation by FMC.  Section 1720 states that"[i]n actions arising out of the maintenance or use of a motor vehicle, there shall be no right of subrogation or reimbursement from a claimant's tort recovery with respect to . . . benefits . . . payable under section 1719. [Footnote 1]"Section 1719 refers to benefit payments by "[a]ny program, group contract or other arrangement." [Footnote 2] Page 498 U. S. 56Respondent, proceeding in diversity, then sought and received a declaratory judgment in Federal District Court that § 1720 prohibits FMC's exercise of subrogation rights on Holliday's claim against the driver.  The United States Court of Appeals for the Third Circuit affirmed.  885 F.2d 79 (1989).  The court held that § 1720, unless preempted, bars FMC from enforcing its contractual subrogation provision.  According to the court, ERISA preempts § 1720 if ERISA's "deemer clause," § 514(b)(2)(B), 29 U.S.C. § 1144(b)(2)(B), exempts the Plan from state subrogation laws.  The Court of Appeals, citing Northern Group Services, Inc. v. Auto Owners Ins. Co., 833 F.2d 85, 91-94 (CA6 1987), cert. denied, 486 U.S. 1017 (1988), determined that "the deemer clause [was] meant mainly to reach back-door attempts by states to regulate core ERISA concerns in the guise of insurance regulation."  885 F.2d  at 86.  Pointing out that the parties had not suggested that the Pennsylvania antisubrogation law addressed "a core type of ERISA matter which Congress sought to protect by the preemption provision," id. at 90, the court concluded that the Pennsylvania law is not preempted.  The Third Circuit's holding conflicts with decisions of other Circuit Courts that have construed ERISA's deemer clause to protect self-funded plans from all state insurance regulation.  See, e.g., Baxter v. Lynn, 886 F.2d 182, 186 (CA8 1989); Reilly v. Blue Cross and Blue Shield United of Wisconsin, 846 F.2d 416, 425-426 (CA7), cert. denied, 488 U.S. 856 (1988).  We granted certiorari to resolve this conflict. 493 U.S. 1068 (1990), and now reverse.IIIn determining whether federal law preempts a state statute, we look to congressional intent.""Preemption may be either express or implied, and is compelled whether Congress' Page 498 U. S. 57 command is explicitly stated in the statute's language or implicitly contained in its structure and purpose."  " Shaw v. Delta Air Lines, Inc., 463 U. S. 85,  463 U. S. 95 (1983) (quoting Fidelity Federal Savings & Loan Assn. v. De la Cuesta, 458 U. S. 141,  458 U. S. 152-153 (1982), in turn quoting Jones v. Rath Packing Co., 430 U. S. 519,  430 U. S. 525 (1977)); See also Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc., 467 U. S. 837,  467 U. S. 842-843 (1984) ("If the intent of Congress is clear, that is the end of the matter; for the court . . . must give effect to the unambiguously expressed intent of Congress" (footnote omitted)).  We"begin with the language employed by Congress and the assumption that the ordinary meaning of that language accurately expresses the legislative purpose."Park 'N Fly, Inc. v. Dollar Park and Fly, Inc., 469 U. S. 189,  469 U. S. 194 (1985).  Three provisions of ERISA speak expressly to the question of preemption:"Except as provided in subsection (b) of this section [the saving clause], the provisions of this subchapter and subchapter III of this chapter shall supersede any and all State laws insofar as they may now or hereafter relate to any employee benefit plan."§ 514(a), as set forth in 29 U.S.C. § 1144(a) (preemption clause)."Except as provided in subparagraph (B) [the deemer clause], nothing in this subchapter shall be construed to exempt or relieve any person from any law of any State which regulates insurance, banking, or securities."§ 514(b)(2)(A), as set forth in 29 U.S.C. § 1144(b)(2)(A) (saving clause)."Neither an employee benefit plan . . . nor any trust established under such a plan, shall be deemed to be an insurance company or other insurer, bank, trust company, or investment company or to be engaged in the business of insurance or banking for purposes of any law of any State purporting to regulate insurance companies, insurance contracts, banks, trust companies, or Page 498 U. S. 58 investment companies."§ 514(b)(2)(B), as set forth in 29 U.S.C. § 1144(b)(2)(B) (deemer clause).We indicated in Metropolitan Life Ins. Co. v. Massachusetts, 471 U. S. 724 (1985), that these provisions "are not a model of legislative drafting."  Id. at  471 U. S. 739.  Their operation is nevertheless discernible.  The preemption clause is conspicuous for its breadth.  It establishes as an area of exclusive federal concern the subject of every state law that "relate[s] to" an employee benefit plan governed by ERISA.  The saving clause returns to the States the power to enforce those state laws that "regulat[e] insurance," except as provided in the deemer clause.  Under the deemer clause, an employee benefit plan governed by ERISA shall not be "deemed" an insurance company, an insurer, or engaged in the business of insurance for purposes of state laws "purporting to regulate" insurance companies or insurance contracts.IIIPennsylvania's antisubrogation law "relate[s] to" an employee benefit plan.  We made clear in Shaw v. Delta Air Lines, supra, that a law relates to an employee welfare plan if it has "a connection with or reference to such a plan."  Id., 463 U.S. at  463 U. S. 96-97 (footnote omitted).  We based our reading in part on the plain language of the statute.  Congress used the words "relate to' in § 514(a) [the preemption clause] in their broad sense."  Id. at  463 U. S. 98.  It did not mean to preempt only state laws specifically designed to affect employee benefit plans.  That interpretation would have made it unnecessary for Congress to enact ERISA § 514(b)(4), 29 U.S.C. § 1144(b)(4), which exempts from preemption "generally" applicable criminal laws of a State.  We also emphasized that to interpret the preemption clause to apply only to state laws dealing with the subject matters covered by ERISA, such as reporting, disclosure, and fiduciary duties, would be incompatible with the provision's legislative history because the House and Senate versions of the bill that became ERISA Page 498 U. S. 59 contained limited preemption clauses, applicable only to state laws relating to specific subjects covered by ERISA. [Footnote 3]  These were rejected in favor of the present language in the Act, "indicat[ing] that the section's preemptive scope was as broad as its language."  Shaw v. Delta Air Lines, 463 U.S. at  463 U. S. 98.	Pennsylvania's antisubrogation law has a "reference" to benefit plans governed by ERISA.  The statute states that"[i]n actions arising out of the maintenance or use of a motor vehicle, there shall be no right of subrogation or reimbursement from a claimant's tort recovery with respect to . . . benefits . . . paid or payable under section 1719."75 Pa.Cons.Stat. § 1720 (1987).  Section 1719 refers to "[a]ny program, group contract or other arrangement for payment of benefits."  These terms"includ[e], but [are] not limited to, benefits payable by a hospital plan corporation or a professional health service corporation."§ 1719 (emphasis added).The Pennsylvania statute also has a "connection" to ERISA benefit plans.  In the past, we have not hesitated to apply ERISA's preemption clause to state laws that risk subjecting plan administrators to conflicting state regulations.  See, e.g., Shaw v. Delta Air Lines, supra, at  463 U. S. 95-100 (state laws making unlawful plan provisions that discriminate on the basis of pregnancy and requiring plans to provide specific benefits "relate to" benefit plans); Alessi v. Raybestos-Manhattan, Page 498 U. S. 60 Inc., 451 U. S. 504,  451 U. S. 523-526 (1981) (state law prohibiting plans from reducing benefits by amount of workers' compensation awards "relate[s] to" employee benefit plan).  To require plan providers to design their programs in an environment of differing State regulations would complicate the administration of nationwide plans, producing inefficiencies that employers might offset with decreased benefits.   See Fort Halifax Packing Co. v. Coyne, 482 U. S. 1,  482 U. S. 10 (1987).  Thus, where a "patchwork scheme of regulation would introduce considerable inefficiencies in benefit program operation," we have applied the preemption clause to ensure that benefit plans will be governed by only a single set of regulations.  Id. at  482 U. S. 11.Pennsylvania's antisubrogation law prohibits plans from being structured in a manner requiring reimbursement in the event of. recovery from a third party.  It requires plan providers to calculate benefit levels in Pennsylvania based on expected liability conditions that differ from those in States that have not enacted similar antisubrogation legislation.  Application of differing state subrogation laws to plans would therefore frustrate plan administrators' continuing obligation to calculate uniform benefit levels nationwide.  Accord, Alessi v. Raybestos-Manhattan, Inc., supra, (state statute prohibiting offsetting worker compensation payments against pension benefits preempted, since statute would force employer either to structure all benefit payments in accordance with state statute or adopt different payment formulae for employers inside and outside State).  As we stated in Fort Halifax,"[t]he most efficient way to meet these [administrative] responsibilities is to establish a uniform administrative scheme which provides a set of standard procedures to guide processing of claims and disbursement of benefits."Fort Halifax Packing Co. v. Coyne, supra, at  482 U. S. 9.There is no dispute that the Pennsylvania law falls within ERISA's insurance saving clause, which provides,"[e]xcept as provided in [the deemer clause], nothing in this subchapter Page 498 U. S. 61 shall be construed to exempt or relieve any person from any law of any State which regulates insurance,"§ 514(b)(2)(A), 29 U.S.C. § 1144(b)(2)(A) (emphasis added).  Section 1720 directly controls the terms of insurance contracts by invalidating any subrogation provisions that they contain.  See Metropolitan Life, 471 U.S. at  471 U. S. 740-741.  It does not merely have an impact on the insurance industry; it is aimed at it.  See Pilot Life Ins. Co. v. Dedeaux, 481 U. S. 41,  481 U. S. 50 (1987).  This returns the matter of subrogation to state law.  Unless the statute is excluded from the reach of the saving clause by virtue of the deemer clause, therefore, it is not preempted.We read the deemer clause to exempt self-funded ERISA plans from state laws that "regulat[e] insurance" within the meaning of the saving clause.  By forbidding States to deem employee benefit plans "to be an insurance company or other insurer . . . or to be engaged in the business of insurance," the deemer clause relieves plans from state laws "purporting to regulate insurance."  As a result, self-funded ERISA plans are exempt from state regulation insofar as that regulation "relate[s] to" the plans.  State laws directed toward the plans are preempted because they relate to an employee benefit plan but are not "saved" because they do not regulate insurance.  State laws that directly regulate insurance are "saved" but do not reach self-funded employee benefit plans because the plans may not be deemed to be insurance companies, other insurers, or engaged in the business of insurance for purposes of such state laws.  On the other hand, employee benefit plans that are insured are subject to indirect state insurance regulation.  An insurance company that insures a plan remains an insurer for purposes of state laws "purporting to regulate insurance" after application of the deemer clause.  The insurance company is therefore not relieved from state insurance regulation.  The ERISA plan is consequently bound by state insurance regulations insofar as they apply to the plan's insurer. Page 498 U. S. 62Our reading of the deemer clause is consistent with Metropolitan Life Ins. Co. v. Massachusetts, supra.  That case involved a Massachusetts statute requiring certain self-funded benefit plans and insurers issuing group health policies to plans to provide minimum mental health benefits.  Id. 471 U.S. at  471 U. S. 734.  In pointing out that Massachusetts had never tried to enforce the portion of the statute pertaining directly to benefit plans, we stated"[i]n light of ERISA's 'deemer clause,' which states that a benefit plan shall not 'be deemed an insurance company' for purposes of the insurance saving clause, Massachusetts has never tried to enforce [the statute] as applied to benefit plans directly, effectively conceding that such an application of [the statute] would be preempted by ERISA's preemption clause."Id. at  471 U. S. 735, n. 14 (citations omitted).  We concluded that the statute, as applied to insurers of plans, was not preempted because it regulated insurance and was therefore saved.  Our decision, we acknowledged,"results in a distinction between insured and uninsured plans, leaving the former open to indirect regulation while the latter are not."Id. at  471 U. S. 747."By so doing, we merely give life to a distinction created by Congress in the 'deemer clause,' a distinction Congress is aware of, and one it has chosen not to alter."Ibid. (footnote omitted).Our construction of the deemer clause is also respectful of the presumption that Congress does not intend to preempt areas of traditional state regulation.  See Jones v. Rath Packing Co., 430 U.S. at  430 U. S. 625.  In the McCarran-Ferguson Act, 15 U.S.C. § 1011 et seq., Congress provided that the"business of insurance, and every person engaged therein, shall be subject to the laws of the several States which relate to the regulation or taxation of such business."15 U.S.C. § 1012(a).  We have identified laws governing the "business of insurance" in the Act to include not only direct regulation of the insurer but also regulation of the substantive terms of insurance contracts.  Metropolitan Life Ins. Co. v. Massachusetts, supra, 471 U.S. at  471 U. S. 742-744.  Page 498 U. S. 63 By recognizing a distinction between insurers of plans and the contracts of those insurers, which are subject to direct state regulation, and self-insured employee benefit plans governed by ERISA, which are not, we observe Congress' presumed desire to reserve to the States the regulation of the "business of insurance."Respondent resists our reading of the deemer clause, and would attach to it narrower significance.  According to the deemer clause,"[n]either an employee benefit plan . . . nor any trust established under such a plan, shall be deemed to be an insurance company or other insurer, bank, trust company, or investment company or to be engaged in the business of insurance or banking for purposes of any law of any State purporting to regulate insurance companies [or] insurance contracts."§ 514(b)(2)(B), 29 U.S.C. § 1144(b)(2)(B) (emphasis added).  Like the Court of Appeals, respondent would interpret the deemer clause to except from the saving clause only state insurance regulations that are pretexts for impinging upon core ERISA concerns.  The National Conference of State Legislatures et al. as amici curiae in support of respondent, offer an alternative interpretation of the deemer clause.  In their view, the deemer clause precludes States from deeming plans to be insurers only for purposes of state laws that apply to insurance as a business, such as laws relating to licensing and capitalization requirements.These views are unsupported by ERISA's language.  Laws that purportedly regulate insurance companies or insurance contracts are laws having the "appearance of" regulating or "intending" to regulate insurance companies or contracts.  Black's Law Dictionary 1236 (6th ed.1990).  Congress' use of the word does not indicate that it directed the deemer clause solely at deceit that it feared state legislatures would practice.  Indeed, the Conference Report, in describing the deemer clause, omits the word "purporting," stating,"an employee benefit plan is not to be considered as an insurance company, bank, trust company, or investment Page 498 U. S. 64 company (and is not to be considered as engaged in the business of insurance or banking) for purposes of any State law that regulates insurance companies, insurance contracts, banks, trust companies, or investment companies."H.R.Conf.Rep. No. 93-1280, p. 383 (1974), U.S.Code Cong. & Admin.News 1974, pp. 4639, 5162.Nor, in our view, is the deemer clause directed solely at laws governing the business of insurance.  It is plainly directed at"any law of any State purporting to regulate insurance companies, insurance contracts, banks, trust companies, or investment companies."§ 514(b)(2)(B), 29 U.S.C. § 1144(b)(2)(B).  Moreover, it is difficult to understand why Congress would have included insurance contracts in the preemption clause if it meant only to preempt state laws relating to the operation of insurance as a business.  To be sure, the saving and deemer clauses employ differing language to achieve their ends -- the former saving, except as provided in the deemer clause, "any law of any State which regulates insurance" and the latter referring to "any law of any State purporting to regulate insurance companies [or] insurance contracts."  We view the language of the deemer clause, however, to be either coextensive with or broader, not narrower, than that of the saving clause.  Our rejection of a restricted reading of the deemer clause does not lead to the deemer clause's engulfing the saving clause.  As we have pointed out, supra at ___, the saving clause retains the independent effect of protecting state insurance regulation of insurance contracts purchased by employee benefit plans.Congress intended by ERISA to "establish pension plan regulation as exclusively a federal concern." Alessi v. Raybestos-Manhattan, Inc., 451 U.S. at  451 U. S. 523 (footnote omitted).  Our interpretation of the deemer clause makes clear that, if a plan is insured, a State may regulate it indirectly through regulation of its insurer and its insurer's insurance contracts; if the plan is uninsured, the State may not regulate it.  As a result, employers will not face "conflicting or inconsistent State and local regulation of employee benefit plans.'"  Page 498 U. S. 65 Shaw v. Delta Air Lines, Inc., 463 U.S. at  463 U. S. 99 (quoting remarks of Sen. Williams).  A construction of the deemer clause that exempts employee benefit plans from only those state regulations that encroach upon core ERISA concerns or that apply to insurance as a business would be fraught with administrative difficulties, necessitating definition of core ERISA concerns and of what constitutes business activity.  It would therefore undermine Congress' desire to avoid "endless litigation over the validity of State action," see 120 Cong.Rec. 29942 (1974) (remarks of Sen. Javits), and instead lead to employee benefit plans' expenditure of funds in such litigation.In view of Congress' clear intent to exempt from direct state insurance regulation ERISA employee benefit plans, we hold that ERISA preempts the application of § 1720 of Pennsylvania's Motor Vehicle Financial Responsibility Law to the FMC Salaried Health Care Plan.  We therefore vacate the judgment of the United States Court of Appeals for the Third Circuit, and remand the case for further proceedings consistent with this opinion.It is so ordered
U.S. Supreme CourtFMC Corp. v. Holliday, 498 U.S. 52 (1990)FMC Corporation v. HollidayNo. 89-1048Argued Oct. 2, 1990Decided Nov. 27, 1990498 U.S. 52SyllabusAfter petitioner FMC Corporation's self-funded health care plan (Plan) paid a portion of respondent's medical expenses resulting from an automobile accident, FMC informed respondent that it would seek reimbursement under the Plan's subrogation provision from any recovery she realized in her Pennsylvania negligence action against the driver of the vehicle in which she was injured.  Respondent obtained a declaratory judgment in Federal District Court that § 1720 of Pennsylvania's Motor Vehicle Financial Responsibility Law -- which precludes reimbursement from a claimant's tort recovery for benefit payments by a program, group contract, or other arrangement -- prohibits FMC's exercise of subrogation rights.  The Court of Appeals affirmed, holding that the Employee Retirement Income Security Act of 1974 (ERISA), which applies to employee welfare benefit plans such as FMC's, does not preempt § 1720.Held:  ERISA preempts the application of § 1720 to FMC's Plan.(a) ERISA's preemption clause broadly establishes as an area of exclusive federal concern the subject of every state law that "relate[s] to" a covered employee benefit plan.  Although the statute's saving clause returns to the States the power to enforce those state laws that "regulat[e] insurance," the deemer clause provides that a covered plan shall not be "deemed to be an insurance company or other insurer . . . or to be engaged in the business of insurance" for purposes of state laws "purporting to regulate" insurance companies or insurance contracts.  Pp.  498 U. S. 56-58.(b) Section 1720 "relate[s] to" an employee benefit plan within the meaning of ERISA's preemption provision, since it has both a "connection with" and a "reference to" such a plan.  See Shaw v. Delta Air Lines, Inc., 463 U. S. 85,  463 U. S. 96-97.  Moreover, although there is no dispute that § 1720 "regulates insurance," ERISA's deemer clause demonstrates Congress' clear intent to exclude from the reach of the saving clause self-funded ERISA plans by relieving them from state laws "purporting to regulate insurance."  Thus, such plans are exempt from state regulation insofar as it "relates to" them.  State laws directed toward such plans are preempted because they relate to an employee benefit plan but are not "saved" because they do not regulate insurance.  Page 498 U. S. 53 State laws that directly regulate insurance are "saved," but do not reach self-funded plans because the plans may not be deemed to be insurance companies, other insurers, or engaged in the business of insurance for purposes of such laws.  On the other hand, plans that are insured are subject to indirect state insurance regulation insofar as state laws "purporting to regulate insurance" apply to the plans' insurers and the insurers' insurance contracts.  This reading of the deemer clause is consistent with Metropolitan Life Ins. Co. v. Massachusetts, 471 U. S. 724,  471 U. S. 735, n. 14,  471 U. S. 747, and is respectful of the presumption that Congress does not intend to preempt areas of traditional state regulation, see Jones v. Rath Packing Co., 430 U. S. 519,  430 U. S. 525, including regulation of the "business of insurance," see Metropolitan Life Ins. Co. v. Massachusetts, supra, 471 U.S. at  471 U. S. 742-744.  Narrower readings of the deemer clause -- which would interpret the clause to except from the saving clause only state insurance regulations that are pretexts for impinging on core ERISA concerns or to preclude States from deeming plans to be insurers only for purposes of state laws that apply to insurance as a business, such as laws relating to licensing and capitalization requirements -- are unsupported by ERISA's language, and would be fraught with administrative difficulties, necessitating definition of core ERISA concerns and of what constitutes business activity and thereby undermining Congress' expressed desire to avoid endless litigation over the validity of state action and requiring plans to expend funds in such litigation.
