Public Employees Retirement System of Ohio v. Betts/Opinion of the Court

by Anthony Kennedy

The Age Discrimination in Employment Act of 1967 (ADEA), 81 Stat. 602, as amended, 29 U.S.C. § 621 et seq. (1982 ed. and Supp. V), forbids arbitrary discrimination by public and private employers against employees on account of age. Under § 4(f)(2) of the Act, 29 U.S.C. § 623(f)(2), however, age-based employment decisions taken pursuant to the terms of "any bona fide employee benefit plan such as a retirement, pension, or insurance plan, which is not a subterfuge to evade the purposes of" the Act, are exempt from the prohibitions of the ADEA. In the case before us, we must consider the meaning and scope of the § 4(f)(2) exemption.

* A.

In 1933, the State of Ohio established the Public Employees Retirement System of Ohio (PERS) to provide retirement benef ts for state and local government employees. Public employers and employees covered by PERS make contributions to a fund maintained by PERS to pay benefits to covered employees. Under the PERS statutory scheme, two forms of monthly retirement benefits are available to public employees upon termination of their public employment. Age-and-service retirement benefits are paid to those employees who at the time of their retirement (1) have at least 5 years of service credit and are at least 60 years of age; (2) have 30 years of service credit; or (3) have 25 years of service credit and are at least 55 years of age. Ohio Rev.Code Ann. §§ 145.33, 145.34 (1984 and Supp.1988). Disability retirement benefits are available to employees who suffer a permanent disability, have at least five years of total service credit, and are under the age of 60 at retirement. § 145.35. The requirement that disability retirees be under age 60 at the time of their retirement was included in the original PERS statute, and has remained unchanged since 1959.

Employees who take disability retirement are treated as if they are on leave of absence for the first five years of their retirement. Should their medical conditions improve during that time, they are entitled to be rehired. § 145.39. Employees receiving age-and-service retirement, on the other hand, are not placed on leave of absence, but they are permitted to apply for full-time employment with any public employer covered by PERS after 18 months of retirement. Ohio Rev.Code Ann. § 145.381(C) (1984). Once an individual retires on either age-and-service or disability retirement benefits, he or she continues to receive that type of benefit throughout retirement, regardless of age.

Appellee June M. Betts was hired by the Hamilton County Board of Mental Retardation and Developmental Disabilities as a speech pathologist in 1978. The board is a public agency, and its employees are covered by PERS. In 1984, because of medical problems, appellee became unable to perform her job adequately and was reassigned to a less demanding position. Appellee's medical condition continued to deteriorate, however, and by May 1985, when appellee was 61 years of age, her employer concluded that she was no longer able to perform adequately in any employment capacity. Appellee was given the choice of retiring or undergoing medical testing to determine whether she should be placed on unpaid medical leave. She chose to retire, an option which gave her eligibility for age-and-service retirement benefits from PERS. Because she was over 60 at the time of retirement, however, appellee was denied disability retirement benefits, despite her medical condition.

Before 1976, the fact that appellee's age disqualified her for disability benefits would have had little practical significance, because the formula for calculating disability benefits was almost the same as the formula used to determine age-and-service benefits. In 1976, however, the PERS statutory scheme was amended to provide that disability retirement payments would in no event constitute less than 30 percent of the disability retiree's final average salary. Ohio Rev.Code Ann. § 145.36 (1984). No such floor applies in the case of employees receiving age-and-service retirement payments. The difference was of much significance in appellee's case: her age-and-service retirement benefits amount to $158.50 per month, but she would have received nearly twice that, some $355 per month, had she been permitted to take disability retirement instead.

Appellee filed an age discrimination charge against PERS with the Equal Employment Opportunity Commission, (EEOC), and filed suit in the United States District Court for the Southern District of Ohio, claiming that PERS' refusal to grant her application for disability retirement benefits violated the ADEA. The District Court found that PERS' retirement scheme was discriminatory on its face, in that it denied disability retirement benefits to certain employees on account of their age. Betts v. Hamilton County Bd. of Mental Retardation, 631 F.Supp. 1198, 1202-1203 (1986). The court rejected PERS' reliance on § 4(f)(2) of the ADEA, which exempts from the Act's prohibitions certain actions taken in observance of "the terms of . . . any bona fide employee benefit plan such as a retirement, pension, or insurance plan, which is not a subterfuge to evade the purposes of [the Act]. . . ." 29 U.S.C. § 623(f)(2). Relying on interpretive regulations promulgated by the EEOC, the District Court held that employee benefit plans qualify for the § 4(f)(2) exemption only if any age-related reductions in employee benefits are justified by the increased cost of providing those benefits to older employees. Because the PERS plan provided for a reduction in available benefits at age 60, a reduction not shown to be justified by considerations of increased cost, the court concluded that PERS' plan was not entitled to claim the protection of the § 4(f)(2) exemption. 631 F.Supp., at 1203-1204. ^[1]

A divided panel of the Court of Appeals affirmed. Betts v. Hamilton County Bd. of Mental Retardation and Developmental Disabilities, 848 F.2d 692 (CA6 1988). The majority agreed with the District Court that the § 4(f)(2) exemption is available only to those retirement plans that can provide age-related cost justifications or "a substantial business purpose" for any age-based reduction in benefits. Id., at 694. The majority rejected PERS' reliance on United Air Lines, Inc. v. McMann, 434 U.S. 192, 98 S.Ct. 444, 54 L.Ed.2d 402 (1977), which held that retirement plans adopted prior to the enactment of the ADEA need not be justified by any business purpose, concluding that Congress had "expressly repudiated" this decision when it amended the ADEA in 1978. 848 F.2d, at 694. Because PERS had failed to provide any evidence that its discrimination against older workers was justified by age-related cost considerations, the majority concluded that summary judgment was appropriate.

Judge Wellford dissented. Noting that PERS' plan was adopted long before enactment of the ADEA, he argued that under United Air Lines, Inc. v. McMann, supra, it could not be a "subterfuge to evade the purposes" of the Act. Judge Wellford rejected the EEOC's regulations requiring cost justifications for all age-based reductions in benefits, finding that nothing in the statute's language imposed such a requirement. We noted probable jurisdiction, 488 U.S. 907, 109 S.Ct. 256, 102 L.Ed.2d 245 (1988), and now reverse.

Under § 4(a)(1) of the ADEA, it is unlawful for an employer

"to fail or refuse to hire or discharge any individual or otherwise discriminate against any individual with respect to his compensation, terms, conditions, or privileges of employment, because of such individual's age." 29 U.S.C. § 623(a)(1).

Notwithstanding this general prohibition, however, § 4(f)(2) of the ADEA provides that it is not unlawful for an employer

"to observe the terms of . . . any bona fide employee benefit plan such as a retirement, pension, or insurance plan, which is not a subterfuge to evade the purposes of this chapter, except that no such employee benefit plan shall excuse the failure to hire any individual, and no such . . . employee benefit plan shall require or permit the involuntary retirement of any individual . . . because of the age of such individual." 29 U.S.C. § 623(f)(2).

On its face, the PERS statutory scheme renders covered employees ineligible for disability retirement once they have attained age 60. Ohio Rev.Code Ann. § 145.35 (1984). PERS' refusal to grant appellee's applicatio for disability benefits therefore qualifies as an action "to observe the terms of" the plan. All parties apparently concede, moreover, that PERS' plan is "bona fide," in that it " 'exists and pays benefits.' " McMann, 434 U.S., at 194, 98 S.Ct., at 446; see id., at 206-207, 98 S.Ct., at 451-452 (WHITE, J., concurring in judgment). Finally, whatever the precise meaning of the phrase "any . . . employee benefit plan such as a retirement, pension, or insurance plan," see infra, at 173-175, fn. 4, it is apparent that a disability retirement plan falls squarely within that category. Cf. 29 CFR § 1625.10(f)(1)(ii) (1988). Accordingly, PERS is entitled to the protection of the § 4(f)(2) exemption unless its plan is "a subterfuge to evade the purposes of" the Act. ^[2]

We first construed the meaning of "subterfuge" under § 4(f)(2) in United Air Lines, Inc. v. McMann, supra. In McMann, the employer's retirement plan required employees to retire at the age of 60. After being forced to retire by the terms of the plan, McMann sued under the ADEA, claiming that the forced retirement was a violation of the Act, and that the mandatory retirement provision was not protected by the § 4(f)(2) exemption because it was a subterfuge to evade the purposes of the Act. ^[3] We rejected both positions. With respect to mandatory retirement, we found that the statutory language and legislative history provided no support for the proposition that Congress intended to forbid age-based mandatory retirement.

Turning to the claim that the mandatory retirement provision was a "subterfuge to evade the purposes of" the Act, we rejected the conclusion of the court below that forced retirement on the basis of age must be deemed a subterfuge absent some business or economic purpose for the age-based distinction. Instead, we held that the term "subterfuge" must be given its ordinary meaning as "a scheme, plan, stratagem, or artifice of evasion." Id., at 203, 98 S.Ct., at 450. Viewed in this light, the retirement plan at issue could not possibly be characterized as a subterfuge to evade the purposes of the Act, since it had been established in 1941, long before the Act was enacted. As we observed, "[t]o spell out an intent in 1941 to evade a statutory requirement not enacted until 1967 attributes, at the very least, a remarkable prescience to the employer. We reject any such per se rule requiring an employer to show an economic or business purpose in order to satisfy the subterfuge language of the Act." Ibid.

As an initial matter, appellee asserts that McMann is no longer good law. She points out that in 1978, less than a year after McMann was decided, Congress amended § 4(f)(2) to overrule McMann § validation of mandatory retirement based on age. See Pub.L. 95-256, § 2(a), 92 Stat. 189. The result of that amendment was the addition of what now is the final clause of § 4(f)(2).

The legislative history of the 1978 amendment contains various references to the definition of subterfuge, and according to appellee these reveal clear congressional intent to disapprove the reasoning of McMann. The Conference Committee Report on the 1978 amendment, for example, expressly discusses and rejects McMann, stating that "[p]lan provisions in effect prior to the date of enactment are not exempt under section 4(f)(2) by virtue of the fact that they antedate the act or these amendments." H.R.Conf.Rep. No. 95-950, p. 8 (1978), U.S.Code Cong. & Admin.News 1978, pp. 504, 511. See also 124 Cong.Rec. 7881 (1978) (remarks of Rep. Hawkins) ("The conferees specifically disagree with the Supreme Court's holding and reasoning in [McMann], particularly its conclusion that an employee benefit plan which discriminates on the basis of age is protected by section 4(f)(2) because it predates the enactment of the ADEA"); id., at 8219 (remarks of Sen. Javits); id., at 7888 (remarks of Rep. Waxman).

PERS disputes appellee's interpretation of this legislative history, asserting that it refers only to benefit plans that permit involuntary retirement and not to the more general issue whether a pre-Act plan can be a subterfuge in other circumstances. We need not resolve this dispute, however. The 1978 amendment to the ADEA did not add a definition of the term "subterfuge" or modify the language of § 4(f)(2) in any way, other than by inserting the final clause forbidding mandatory retirement based on age. We have observed on more than one occasion that the interpretation given by one Congress (or a committee or Member thereof) to an earlier statute is of little assistance in discerning the meaning of that statute. See Weinberger v. Rossi, 456 U.S. 25, 35, 102 S.Ct. 1510, 1517, 71 L.Ed.2d 715 (1982); Consumer Product Safety Comm'n v. GTE Sylvania, Inc., 447 U.S. 102, 118, and n. 13, 100 S.Ct. 2051, 2061, and n. 13, 64 L.Ed.2d 766 (1980); United States v. Southwestern Cable Co., 392 U.S. 157, 170, 88 S.Ct. 1994, 2001, 20 L.Ed.2d 1001 (1968); Rainwater v. United States, 356 U.S. 590, 593, 78 S.Ct. 946, 949, 2 L.Ed.2d 996 (1958); see also McMann, supra, at 200, n. 7, 98 S.Ct., at 449, n. 7. Congress changed the specific result of McMann by adding a final clause to § 4(f)(2), but it did not change the controlling, general language of the statute. As Congress did not amend the relevant statutory language, we see no reason to depart from our holding in McMann that the term "subterfuge" is to be given its ordinary meaning, and that as a result an employee benefit plan adopted prior to enactment of the ADEA cannot be a subterfuge. See EEOC v. Cargill, Inc., 855 F.2d 682, 686 (CA10 1988); EEOC v. County of Orange, 837 F.2d 420, 422 (CA9 1988).

According to PERS, our reaffirmation of McMann should resolve this case. The PERS system was established by statute in 1933, and the rule that employees over age 60 may not qualify for disability retirement benefits has remained unchanged since 1959. The ADEA was not made applicable to the States until 1974. See Pub.L. 93-259, § 28(a)(2), 88 Stat. 74, codified at 29 U.S.C. § 630(b)(2). Since the age-60 requirement predates application of the ADEA to PERS, PERS argues that, under McMann, its plan cannot be a subterfuge to evade the purposes of the ADEA.

While McMann remains of considerable relevance to our decision here, we reject the argument that it is dispositive. It is true that the age-60 rule was adopted before 1974, and is thus insulated under McMann from challenge as a subterfuge. The plan provision attacked by appellee, however, is the rule that disability retirees automatically receive a minimum of 30 percent of their final average salary upon retirement, while disabled employees who retire after age 60 do not. The 30 percent floor was not added to the plan until 1976, and to the extent this new rule increased the age-based disparity caused by the pre-Act age limitation, McMann does not insulate it from challenge. See EEOC v. Cargill, supra, at 686, n. 4; EEOC v. County of Orange, supra, at 423; EEOC v. Home Ins. Co., 672 F.2d 252, 259, and n. 9 (CA2 1982). No "remarkable prescience" would have been required of PERS in 1976 for it to formulate the necessary intent to evade the ADEA, and thus the autom tic rule of McMann is inapplicable. See 434 U.S., at 203, 98 S.Ct., at 450. Accordingly, we must turn to an inquiry into the precise meaning of the § 4(f)(2) exemption in the context of post-Act plans.

Appellee and her amici say that § 4(f)(2) protects age-based distinctions in employee benefit plans only when justified by the increased cost of benefits for older workers. They cite an interpretive regulation promulgated by the Department of Labor, the agency initially charged with enforcing the Act, in 1979. 44 Fed.Reg. 30658-30662 (1979), codified at 29 CFR § 860.120 (1980), redesignated 29 CFR § 1625.10 (1988). The regulation recites that the purpose of the exemption "is to permit age-based reductions in employee benefit plans where such reductions are justified by significant cost considerations," and that "benefit levels for older workers may be reduced to the extent necessary to achieve approximate equivalency in cost for older and younger workers." § 1625.10(a)(1). With respect to disability benefits in particular, the regulation provides that "[r]eductions on the basis of age in the level or duration of benefits available for disability are justifiable only on the basis of age-related cost considerations. . . ." § 1625.10(f)(1)(ii). Under these provisions, employers may reduce the value of the benefits provided to older workers as necessary to equalize costs for workers of all ages, but they cannot exclude older workers from the coverage of their benefit plans altogether.

The requirement that employers show a cost-based justification for age-related reductions in benefits appears nowhere in the statute itself. The EEOC as amicus contends that this rule can be drawn either from the statutory requirement that age-based distinctions in benefit plans not be a subterfuge to evade the purposes of the Act, or from the portion of § 4(f)(2) limiting its scope to actions taken pursuant to "any bona fide employee benefit plan such as a retirement, pension, or insurance plan." Brief for EEOC as Amicus Curiae 9-14. We consider these alternatives in turn.

The regulations define "subterfuge" as follows: "In general, a plan or plan provision which prescribes lower benefits for older employees on account of age is not a 'subterfuge' within the meaning of section 4(f)(2), provided that the lower level of benefits is justified by age-related cost considerations." 29 CFR § 1625.10(d) (1988). Various lower courts have accepted this definition. E.g., EEOC v. Mt. Lebanon, 842 F.2d 1480, 1489 (CA3 1988); see also Cipriano v. Board of Education of North Tonawanda School Dist., 785 F.2d 51, 57-58 (CA2 1986). As the analysis in McMann makes apparent, however, this approach to the definition of subterfuge cannot be squared with the plain language of the statute. Although McMann § holding, that pre-Act plans can never be a subterfuge, is not dispositive here, its reasoning is nonetheless controlling, for we stated in that case that "subterfuge" means "a scheme, plan, stratagem, or artifice of evasion," which, in the context of § 4(f)(2), connotes a specific "intent . . . to evade a statutory requirement." 434 U.S., at 203, 98 S.Ct., at 450. The term thus includes a subjective element that the regulation's objective cost-justification requirement fails to acknowledge.

Ignoring this inconsistency with the plain language of the statute, appellee and the EEOC suggest that the regulation represents a contemporaneous and consistent interpretation of the ADEA by the agencies responsible for the Act's enforcement and is therefore entitled to special deference. See EEOC v. Associated Dry Goods Corp., 449 U.S. 590, 600, n. 17, 101 S.Ct. 817, 823, n. 17, 66 L.Ed.2d 762 (1981); see also Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc., 467 U.S. 837, 104 S.Ct. 2778, 81 L.Ed.2d 694 (1984). But, of course, no deference is due to agency interpretations at odds with the plain language f the statute itself. Even contemporaneous and longstanding agency interpretations must fall to the extent they conflict with statutory language.

Contrary to the suggestion of the EEOC and appellee, moreover, the cost-justification requirement was not adopted contemporaneously with enactment of the ADEA. The cost-justification rule had its genesis in an interpretive bulletin issued by the Department of Labor in January 1969. 34 Fed.Reg. 322, 323, codified at 29 CFR § 860.120(a) (1970). To be sure, that regulation provided that plans which reduced benefits on the basis of age would "be considered in compliance with the statute" if the benefit reductions were justified by age-related cost considerations, but it did not purport to exclude from the § 4(f)(2) exemption all plans that could not meet a cost-justification requirement. ^[4] Rather, this original version of the cost-justification rule was nothing more than a safe harbor, a nonexclusive objective test for employers to use in determining whether they could be certain of qualifying for the § 4(f)(2) exemption. It was not until 1979 that this regulatory safe harbor was transformed into the exclusive means of escaping classification as a subterfuge.

Appellee and her amici rely in large part on the legislative history of the ADEA and the 1978 amendments. In view of our interpretation of the plain statutory language of the subterfuge requirement, however, this reliance on legislative history is misplaced. See Davis v. Michigan Dept. of Treasury, 489 U.S. 803, 808, n. 3, 109 S.Ct. 1500, 1504, n. 3, 103 L.Ed.2d 891 (1989); McMann, 434 U.S., at 199, 98 S.Ct., at 448. The "subterfuge" exception to the § 4(f)(2) exemption cannot be limited in the manner suggested by the regulation.

The second possible source of authority for the cost-justification rule is the statute's requirement that the § 4(f)(2) exemption be available only in the case of "any bona fide employee benefit plan such as a retirement, pension, or insurance plan." The EEOC argues, and some courts have held, that the phrase "such as a retirement, pension, or insurance plan" is intended to limit the protection of § 4(f)(2) to those plans which have a cost justification for all age-based differentials in benefits. See EEOC v. Westinghouse Electric Corp., 725 F.2d 211, 224 (CA3 1983), cert. denied, 469 U.S. 820, 105 S.Ct. 92, 83 L.Ed.2d 38 (1984); EEOC v. Borden's, Inc., 724 F.2d 1390, 1396 (CA9 1984). The argument is as follows: the types of plans listed in the statute share the common characteristic that the cost of the benefits they provide g nerally rises with the age of their beneficiaries. This common characteristic suggests that Congress intended the § 4(f)(2) exemption to cover only those plans in which costs rise with age. The obvious explanation for the limitation on the scope of § 4(f)(2), the argument continues, is that the purpose of the exemption is to permit employers to reduce overall benefits paid to older workers only to the extent necessary to equalize costs for older and younger workers.

There are a number of difficulties with this explanation for the cost-justification requirement. Perhaps most obvious, it requires us to read a great deal into the language of this clause of § 4(f)(2), language that appears on its face to be nothing more than a listing of the general types of plans that fall within the category of "employee benefit plan." The statute's use of the phrase "any employee benefit plan" seems to imply a broad scope for the statutory exemption, and the "such as" clause suggests enumeration by way of example, not an exclusive listing. Nor is it by any means apparent that the types of plans mentioned were intentionally selected because the cost to the employer of the benefits provided by these plans tends to increase with age. Indeed, many plans that fall within these categories do not share that particular attribute at all, defined-contribution pension plans perhaps being the most obvious example. ^[5] We find it quite difficult to believe that Congress would have chosen such a circuitous route to the result urged by appellee and the EEOC.

The interpretation is weakened further by the fact that the regulation itself does not support it. According to 29 CFR § 1625.10(b) (1988), "[a]n 'employee benefit plan' is a plan, such as a retirement, pension, or insurance plan, which provides employees with what are frequently referred to as 'fringe benefits.' " This definition makes no mention of the limitation urged by the EEOC, and indeed seems sufficiently broad to encompass a wide variety of plans providing fringe benefits to employees, regardless of whether the cost of those benefits increases with age. The regulation's discussion of the cost-justification requirement is reserved for the subsection defining "subterfuge." § 1625.10(d). ^[6] Under these circumstances, this aspect of the EEOC's argument is entitled to little, if any, deference. Cf. Bowen v. Georgetown University Hospital, 488 U.S. 204, 212-213, 109 S.Ct. 468, 473-474, 102 L.Ed.2d 493 (1988).

For these reasons, we conclude that the phrase "any bona fide employee benefit plan such as a retirement, pension, or insurance plan" cannot reasonably be limited to benefit plans in which all age-based reductions in benefits are justified by age-related cost considerations. Accordingly, the interpretive regulation construing § 4(f)(2) to include a cost-justification requirement is contrary to the plain language of the statute and is invalid.

Having established that the EEOC's definition of subterfuge is invalid, we turn to the somewhat more difficult task of determining the precise meaning of the term as applied to post-Act plans. We begin, as always, with the language of the statute itself.

The protection of § 4(f)(2) is unavailable to any employee benefit plan "which is a subterfuge to evade the purposes of" the Act. As set forth in § 2(b) of the ADEA, the purposes of the Act are "to promote employment of older persons based on their ability rather than age; to prohibit arbitrary age discrimination in employment; to help employers and workers find ways of meeting problems arising from the impact of age on employment." 29 U.S.C. § 621(b). On the facts of this case, the only purpose that the PERS plan could be a "subterfuge to evade" is the goal of eliminating "arbitrary age discrimination in employment."

As the presence of the various exemptions and affirmative defenses contained in § 4(f) illustrates, Congress recognized that not all age discrimination in employment is "arbitrary." In order to determine the type of age discrimination that Congress sought to eliminate as arbitrary, we must look for guidance to the substantive prohibitions of the Act itself, for these provide the best evidence of the nature of the evils Congress sought to eradicate. Indeed, our decision in McMann compels this approach, for it rejected the contention that the purposes of the Act can be distinguished from the Act itself: "The distinction relied on is untenable because the Act is the vehicle by which its purposes are expressed and carried out; it is difficult to conceive of a subterfuge to evade the one which does not also evade the other." 434 U.S., at 198, 98 S.Ct., at 448. Accordingly, a post-Act plan cannot be a subterfuge to evade the ADEA's purpose of banning arbitrary age discrimination unless it discriminates in a manner forbidden by the substantive provisions of the Act.

Section 4(a), the ADEA's primary enforcement mechanism against age discrimination by employers, forbids employers

"(1) to fail or refuse to hire or to discharge any individual or otherwise discriminate against any individual with respect to his compensation, terms, conditions, or privileges of employment, because of such individual's age;

"(2) to limit, segregate, or classify his employees in any way which would deprive or tend to deprive any individual of employment opportunities or otherwise adversely affect his status as an employee, because of such individual's age; or

"(3) to reduce the wage rate of any employee in order to comply w th this chapter." 29 U.S.C. § 623(a).

The phrase "compensation, terms, conditions, or privileges of employment" in § 4(a)(1) can be read to encompass employee benefit plans of the type covered by § 4(f)(2). Such an interpretation, however, would in effect render the § 4(f)(2) exemption nugatory with respect to post-Act plans. Any benefit plan that by its terms mandated discrimination against older workers would also be facially irreconcilable with the prohibitions in § 4(a)(1) and, therefore, with the purposes of the Act itself. It is difficult to see how a plan provision that expressly mandates disparate treatment of older workers in a manner inconsistent with the purposes of the Act could be said not to be a subterfuge to evade those purposes, at least where the plan provision was adopted after enactment of the ADEA.

On the other hand, if § 4(f)(2) is viewed as exempting the provisions of a bona fide benefit plan from the purview of the ADEA so long as the plan is not a method of discriminating in other, non-fringe-benefit aspects of the employment relationship, both statutory provisions can be given effect. This interpretation of the ADEA would reflect a congressional judgment that age-based restrictions in the employee benefit plans covered by § 4(f)(2) do not constitute the "arbitrary age discrimination in employment" that Congress sought to prohibit in enacting the ADEA. Instead, under this construction of the statute, Congress left the employee benefit battle for another day, and legislated only as to hiring and firing, wages and salaries, and other non-fringe-benefit terms and conditions of employment.

To be sure, this construction of the words of the statute is not the only plausible one. But the alternative interpretation would eviscerate § 4(f)(2). As Justice WHITE wrote in his separate concurrence in McMann, "[b]ecause all retirement plans necessarily make distinctions based on age, I fail to see how the subterfuge language, which was included in the original version of the bill and was carried all the way through, could have been intended to impose a requirement which almost no retirement plan could meet." 434 U.S., at 207, 98 S.Ct., at 452.

Not surprisingly, the legislative history does not support such a self-defeating interpretation, but to the contrary shows that Congress envisioned a far broader role for the § 4(f)(2) exemption. When S. 830, the bill that was to become the ADEA, was originally proposed by the administration in January 1967, it contained no general exemption for benefit plans that differentiated in benefits based on age. ^[7] Senator Javits, one of the principal moving forces behind enactment of age discrimination legislation, generally favored the administration's bill, but believed that a broader exemption for employee benefit plans was needed. Accordingly, he proposed an amendment substantially along the lines of present-day § 4(f)(2). 113 Cong.Rec. 7077 (1967).

One factor motivating Senator Javits' amendment was the concern that, absent some exemption for benefit plans, the Act might "actually encourage employers, faced with the necessity of paying greatly increased premiums, to look for excuses not to hire older workers when they might have done so under a law granting them a degree of flexibility with respect to such matters." Id., at 7076. ^[8] Reducing the cost of hiring older workers was not the only purpose of the proposed amendment, however. Its goals were far more comprehensive. As Senator Javits put it, "the age discrimination law is not the proper place to fight" the battle of ensuring "adequate pension benefits for olde workers," and § 4(f)(2) was therefore intended to be "a fairly broad exemption . . . for bona fide retirement and seniority systems." Ibid. Later, referring to the effect of his proposed amendment on the provisions of employee benefit plans, Senator Javits stated that "[i]f the older worker chooses to waive all of those provisions, then the older worker can obtain the benefits of this act. . . ." Id., at 31255. And finally, in his individual views accompanying the Senate Report on S. 830, Senator Javits observed: "I believe the bill has also been improved by the adoption of language, based on an amendment which I had offered, exempting the observance of bona fide seniority systems and retirement, pension, or other employment benefit plans from its prohibitions." S.Rep. No. 723, 90th Cong., 1st Sess., 14 (1967) (emphasis added).

Other Members of Congress expressed similar views. Senator Yarborough, the principal sponsor and floor manager of the administration bill, observed that § 4(f)(2), "when it refers to retirement, pension, or insurance plan, . . . means that a man who would not have been employed except for this law does not have to receive the benefits of the plan." 113 Cong.Rec. 31255 (1967). Indeed, at least one Congressman opposed the ADEA precisely because it permitted employers to exclude older employees from participation in benefit plans altogether when the terms of the plans mandated that result. Id., at 34745 (remarks of Rep. Smith).

While the Committee Reports on the ADEA do not address the matter in any detail, they do state that § 4(f)(2) "serves to emphasize the primary purpose of the bill-hiring of older workers by permitting employment without necessarily including such workers in employee benefit plans." S.Rep. No. 723, supra, at 4; H.R.Rep. No. 805, 90th Cong., 1st Sess., 4 (1967). That explanation does not support a narrow reading of the § 4(f)(2) exemption. The Committee Reports, moreover, refute a reading of § 4(f)(2) that would limit its protection to pre-Act plans, for they make it clear that the exemption "applies to new and existing employee benefit plans, and to both the establishment and maintenance of such plans." S.Rep. No. 723, supra, at 4; H.R.Rep. No. 805, supra, at 4. In short, the legislative history confirms that the broader reading of § 4(f)(2) is the correct one, and that Congress intended to exempt employee benefit plans from the coverage of the Act except to the extent plans were used as a subterfuge for age discrimination in other aspects of the employment relation.

While this result permits employers wide latitude in structuring employee benefit plans, it does not render the "not a subterfuge" proviso a dead letter. Any attempt to avoid the prohibitions of the Act by cloaking forbidden discrimination in the guise of age-based differentials in benefits will fall outside the § 4(f)(2) exemption. Examples of possible violations of this kind can be given. Under § 4(d) of the ADEA, for example, it is unlawful for an employer to discriminate against an employee who has "opposed any action made unlawful by" the Act or has participated in the filing of any age-discrimination complaints or litigation. Nothing in § 4(f)(2) would insulate from liability an employer who adopted a plan provision formulated to retaliate against such an employee. See 29 CFR § 1625.10(d)(5) (1988). Similarly, while § 4(f)(2) generally protects age-based reductions in fringe benefits, an employer's decision to reduce salaries for all employees while substantially increasing benefits for younger workers might give rise to an inference that the employer was in fact utilizing its benefits plan as a subterfuge for age-based discrimination in wages, an activity forbidden by § 4(a)(1). These examples are not exhaustive, but suffice to illustrate the not-insignificant protections provided to older employees by the subterfuge proviso in the § 4(f)(2) exemption.

As construed above, § 4(f)(2) is not so much a defense to a charge of age discrimination as it is a description of the type of employer conduct that is prohibited in the employee benefit plan context. By requiring a showing of actual intent to discriminate in those aspects of the employment relationship protected by the provisions of the ADEA, § 4(f)(2) redefines the elements of a plaintiff's prima facie case instead of establishing a defense to what otherwise would be a violation of the Act. Thus, when an employee seeks to challenge a benefit plan provision as a subterfuge to evade the purposes of the Act, the employee bears the burden of proving that the discriminatory plan provision actually was intended to serve the purpose of discriminating in some non-fringe-benefit aspect of the employment relation.

This result is supported by our longstanding interpretation of the analogous provision of Title VII, the statute from which "the prohibitions of the ADEA were derived in haec verba." Lorillard v. Pons, 434 U.S. 575, 584, 98 S.Ct. 866, 872, 55 L.Ed.2d 40 (1978). Section 703(h) of Title VII states that

"[n]otwithstanding any other provision of this subchapter, it shall not be an unlawful employment practice for an employer to apply different standards of compensation, or different terms, conditions, or privileges of employment pursuant to a bona fide seniority . . . system, . . . provided that such differences are not the result of an intention to discriminate because of race, color, religion, sex, or national origin. . . ." 42 U.S.C. § 2000e-2(h).

Despite the fact that § 703(h), like § 4(f)(2), appears on first reading to describe an affirmative defense, we have "regarded [§ 703(h) ] not as a defense . . . but as a provision that itself 'delineates which employment practices are illegal and thereby prohibited and which are not.' " Lorance v. AT & T Technologies, Inc., 490 U.S. 900, 908, 109 S.Ct. 2261, 2267, 104 L.Ed.2d 961 (1989) (quoting Franks v. Bowman Transportation Co., 424 U.S. 747, 758, 96 S.Ct. 1251, 1261, 47 L.Ed.2d 444 (1976)). Although the use of the phrase "subterfuge to evade the purposes of [the Act]" in § 4(f)(2) renders the scope of its protection for employee benefit plans broader than the scope of the protection for seniority systems provided by § 703(h), the similar structure and purpose of the two provisions supports the conclusion that ADEA plaintiffs must bear the burden of showing subterfuge.

Applying this structure to the facts here, it follows that PERS's disability retirement plan is the type of plan subject to the § 4(f)(2) exemption, and PERS's refusal to grant appellee's request for disability benefits was required by the terms of the plan. Because appellee has failed to meet her burden of proving that the reduction in benefits at age 60 was the result of an intent to discriminate in some non-fringe-benefit aspect of the employment relation, summary judgment for appellee was inappropriate. On remand, the District Court should give appellee an opportunity to demonstrate the existence of a genuine issue of material fact on this issue. See Celotex Corp. v. Catrett, 477 U.S. 317, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986). The judgment of the Court of Appeals, is reversed and the case is remanded for further proceedings consistent with this opinion.

It is so ordered.

Justice MARSHALL, with whom Justice BRENNAN joins, dissenting.

Notes

1. The District Court also found that PERS' disability retirement plan was not covered by § 4(f)(2) because PERS' actions were not taken pursuant to the terms of the plan, and because the plan impermissibly permits or requires involuntary retirement on the basis of age. 631 F.Supp., at 1204-1205.
2. As a result of the 1978 amendments, § 4(f)(2) cannot be used to justify forced retirement on account of age. Appellee contends, and the District Court found, that appellee was forced to retire under the terms of PERS' plan, and that as a result § 4(f)(2) is unavailable to PERS. The Court of Appeals did not address this question, and we express no opinion on it, leaving its resolution to that court on remand.
3. When McMann was decided, § 4(f)(2) did not contain the final clause excluding from its protection benefit plans that "require or permit the involuntary retirement of any individual . . . because of the age of such individual."
4. As originally promulgated in January 1969, the regulation provided:
5. A defined contribution plan is one in which "the employer's contribution is fixed and the employee receives whatever level of benefits the amount contributed on his behalf will provide." Alabama Power Co. v. Davis, 431 U.S. 581, 593, n. 18, 97 S.Ct. 2002, 2009, n. 18, 52 L.Ed.2d 595 (1977); see 29 U.S.C. § 1002(34). Under this type of plan, the cost of making contributions for any given employee is completely unrelated to that employee's age. The dissent therefore is quite wrong to suggest that these plans "commonly-indeed, almost invariably entail costs that rise with the age of the beneficiary. . . ." Post, at 187.
6. Regulations issued by the Department of Labor in 1969 did provide that "[n]ot all employee benefit plans but only those similar to the kind enumerated in section 4(f)(2) of the Act come within this provision." 34 Fed.Reg. 9708, 9709 (1969), codified at 29 CFR § 860.120(b) (1970). Accordingly, the regulations suggested that "a profit-sharing plan as such would not appear to be within [the] terms" of § 4(f)(2). Ibid. According to the EEOC, this provision reflects the Department's conclusion that § 4(f)(2) "would not shield discrimination against older employees in the provision of profit-sharing benefits because the cost of providing those benefits does not increase as employees age." Brief for EEOC as Amicus Curiae 10-11 n. 4. Nothing in the regulation suggested, however, that the reason for the exclusion of profit-sharing plans was that such plans were not characterized by increasing costs with age. To the contrary, it seems clear that the Department of Labor viewed the § 4(f)(2) exemption as applicable to plans that served the purpose of retirement, pension, or insurance plans, regardless of whether the cost of the benefits provided by such plans rose with the age of their beneficiaries:
7. The administration bill's version of § 4(f)(2) provided that "[i]t shall not be unlawful for an employer, employment agency, or labor organization . . . to separate involuntarily an employee under a retirement policy or system where such policy or system is not merely a subterfuge to evade the purposes of this Act." 113 Cong.Rec. 2794 (1967).
8. Elsewhere, Senator Javits explained that under his version of § 4(f)(2) "an employer will not be compelled to afford older workers exactly the same pension, retirement, or insurance benefits as younger workers and thus employers will not, because of the often extremely high cost of providing certain types of benefits to older workers, actually be discouraged from hiring older workers." Id., at 31254-31255.
