delivered the opinion of the Court.
Section 406(a) of the Employee Retirement Income Security Act of 1974 (ERISA), 88 Stat. 879, bars a fiduciary of an employee benefit plan from causing the plan to engage in certain transactions with a “party in interest.” 29 U. S. C. § 1106(a). Section 502(a)(3) authorizes a “participant, beneficiary, or fiduciary” of a plan to bring a civil aetion to obtain “appropriate equitable relief” to redress violations of ERISA Title I. 29 U. S. C. § 1132(a)(3). The question is whether that authorization extends to a suit against a non-fiduciary “party in interest” to a transaction barred by § 406(a). We hold that it does.
I
Responding to deficiencies in prior law regulating transactions by plan fiduciaries, Congress enacted ERISA § 406(a)(1), which supplements the fiduciary’s general duty of
*242
loyalty to the plan’s beneficiaries, § 404(a), by categorically barring certain transactions deemed “likely to injure the pension plan,”
Commissioner
v.
Keystone Consol. Industries, Inc.,
This ease comes to us on the assumption that an ERISA pension plan (the Ameriteeh Pension Trust (APT)) and a party in interest (respondent Salomon Smith Barney (Salo-mon)) entered into a transaction prohibited by § 406(a) and not exempted by § 408. 1 APT provides pension benefits to employees and retirees of Ameriteeh Corporation and its subsidiaries and affiliates. Salomon, during the late 1980’s, provided broker-dealer services to APT, executing nondis-cretionary equity trades at the direction of APT’s fiduciaries, thus qualifying itself (we assume) as a “party in interest.” See §3(14)(B), 29 U. S. C. § 1002(14)(B) (defining “party in interest” as “a person providing services to [an employee benefit] plan”). During the same period, Salomon sold interests in several motel properties to APT for nearly $21 million. APT’s purchase of the motel interests was directed by National Investment Services of America (NISA), an investment manager to which Ameriteeh had delegated investment *243 discretion over a portion of the plan’s assets, and hence a fiduciary of APT, see §3(21)(A)(i), 29 U. S. C. § lG02(21)(A)(i).
This litigation arose when APT’s fiduciaries — its trustee, petitioner Harris Trust and Savings Bank, and its administrator, petitioner Ameriteeh Corporation — discovered that the motel interests were nearly worthless. Petitioners maintain that the interests had been worthless all along; Salomon asserts, to the contrary, that the interests declined in value due to a downturn in the motel industry. Whatever the true cause, petitioners sued Salomon in 1992 under § 502(a)(3), which authorizes a “participant, beneficiary, or fiduciary” to bring a civil action “to enjoin any act or practice which violates any provision of [ERISA Title I]. .. or . . . to obtain other appropriate equitable relief... to redress such violations.” 29 U. S. C. § 1132(a)(3).
Petitioners claimed, among other things, that NISA, as plan fiduciary, had caused the plan to engage in a per se prohibited transaction under § 406(a) in purchasing the motel interests from Salomon, and that Salomon was liable on account of its participation in the transaction as a nonfiduei-ary party in interest. Specifically, petitioners pointed to § 406(a)(1)(A), 29 U. S. C. § 1106(a)(1)(A), which prohibits a “sale or exchange ... of any property between the plan and a party in interest,” and § 406(a)(1)(D), 29 U. S. C. § 1106(a)(1)(D), whieh prohibits a “transfer to ... a party in interest... of any assets of the plan.” Petitioners sought rescission of the transaction, restitution from Salomon of the purchase price with interest, and disgorgement of Salomon’s profits made from use of the plan assets transferred to it. App. 41.
Salomon moved for summary judgment, arguing that § 502(a)(3), when used to remedy a transaction prohibited by § 406(a), authorizes a suit only against the party expressly constrained by § 406(a) — the fiduciary who caused the plan to enter the transaction — and not against the counterparty to the transaction. See § 406(a)(1), 29 U. S. C. § 1106(a)(1) (“A *244 fiduciary with respect to a plan shall not cause the plan to engage in a transaction, if he knows or should know that such transaction...” (emphasis added)). The District Court denied the motion, holding that ERISA does provide a private cause of action against nonfiduciaries who participate in a prohibited transaction, but granted Salomon’s subsequent motion for certification of the issue for interlocutory appeal under 28 U. S. C. § 1292(b).
The Court of Appeals for the Seventh Circuit reversed.
In doing so, the Seventh Circuit departed from the uniform position of the Courts of Appeals that § 502(a)(3) — and the similarly worded § 502(a)(5), which authorizes civil actions by the Secretary — does authorize a civil action against a non-
*245
fiduciary who participates in a transaction prohibited by § 406(a)(1). See
LeBlanc
v.
Cahill,
H-4
We agree with the Seventh Circuit’s and Salomon’s interpretation of § 406(a). They rightly note that § 406(a) imposes a duty only on the fiduciary that causes the plan to engage in the transaction. See § 406(a)(1), 29 U. S. C. § 1106(a)(1) ("A fiduciary with respect to a plan shall not cause the plan to engage in a transaction, if he knows or should know that such transaction . . .” (emphasis added)). We reject, however, the Seventh Circuit’s and Salomon’s conclusion that, absent a substantive provision of ERISA expressly imposing a duty upon a nonfiduciary party in interest, the nonfidueiary party may not be held liable under § 502(a)(3), one of ERISA’s remedial provisions. Petitioners contend, and we agree, that § 502(a)(3) itself imposes certain duties, and therefore that liability under that provision does not depend on whether ERISA’s substantive provisions impose a specific duty on the party being sued. 2
*246 Section 502 provides:
“(a) . . .
"A civil action may be brought—
“(3) by a participant, beneficiary, or fiduciary (A) to enjoin any act or practice which violates any provision of [ERISA Title I] or the terms of the plan, or (B) to obtain other appropriate equitable relief (i) to redress such violations or (ii) to enforce any provisions of this title or the terms of the plan.” 29 U. S. C. § 1132(a)(3).
This language, to be sure, “does not . . . authorize ‘appropriate equitable relief’
at large,
but only ‘appropriate equitable relief’ for the purpose of ‘redressing any] violations or . . . enforcing] any provisions’ of ERISA or an ERISA plan.”
Peacock
v.
Thomas,
In light of Congress’ precision in these respects, we would ordinarily assume that Congress’ failure to specify proper defendants in § 502(a)(3) was intentional. See
Russello
v.
United States,
Section 502(Z) provides in relevant part:
“(1) In the case of—
“(A) any breach of fiduciary responsibility under (or other violation of) part 4 of this subtitle by a fiduciary, or
“(B) any knowing participation in such a breach or violation by any other person,
*248 “the Secretary shall assess a civil penalty against such fiduciary or other person in an amount equal to 20 percent of the applicable recovery amount.
“(2) For purposes of paragraph (1), the term ‘applicable recovery amount’ means any amount which is recovered from a fiduciary or other person with respect to a breach or violation described in paragraph (1)—
“(A) pursuant to any settlement agreement with the Secretary, or
“(B) ordered by a court to be paid by such fiduciary or other person to a plan or its participants and beneficiaries in a judicial proceeding instituted by the_ Secretary under subsection (a)(2) or (a)(5) of this section.” 29 U.S. C. §§ 1132(Z)(1) — (2).
Section 502(Z) contemplates civil penalty actions by the Secretary against two classes of defendants, fiduciaries and “other person[s].” The latter class concerns us here. Paraphrasing, the Secretary shall assess a civil penalty against an “other person” who “knowing[ly] participates] in” “any ... violation of... part 4 ... by a fiduciary.” And the amount of such penalty is defined by reference to the amount “ordered by a court to be paid by such . . . other person to a plan or its participants and beneficiaries in a judicial proceeding instituted by the Secretary under subsection (a)(2) or (a)(5).” Ibid, (emphasis added).
The plain implication is that the Secretary may bring a civil action under § 502(a)(5) against an “other person” who “knowing[ly] participates]” in a fiduciary’s violation; otherwise, there could be no “applicable recovery amount” from which to determine the amount of the civil penalty to be imposed on the “other person.” This § 502(a)(5) action is available notwithstanding the absence of any ERISA provision explicitly imposing a duty upon an “other person” not to engage in such “knowing participation.” And if the Secretary may bring suit against an “other person” under subsection (a)(5), it follows that a participant, beneficiary, or fi
*249
duciary may bring suit against an “other person” under the similarly worded subsection (a)(3). See
Mertens,
Salomon invokes
Mertens
as articulating an alternative, more restrictive reading of § 502© that does not support the inference we have drawn. In
Mertens,
we suggested, in dictum, that the “other person[s]” in § 502© might be limited to the “eofidueiaries” made expressly liable under § 405(a) for knowingly participating in another fiduciary’s breach of fiduciary responsibility.
Id.,
at 261. So read, § 502© would be consistent with the view that liability under § 502(a)(3) depends entirely on whether the particular defendant violated a duty expressly imposed by the substantive provisions of ERISA Title I. But the
Mertens
dictum did not discuss— understandably, since we were merely flagging the issue, see
Ill
Notwithstanding the text of § 502(a)(3) (as informed by § 502©), Salomon protests that it would contravene common sense for Congress to have imposed civil liability on a party, such as a nonfidueiary party in interest to a § 406(a) transaction, that is not a “wrongdoer” in the sense of violating a duty expressly imposed by the substantive provisions of ERISA Title I. Salomon raises the specter of § 502(a)(3) *250 suits being brought against innocent parties — even those having no connection to the allegedly unlawful “act or practice” — rather than against the true wrongdoer, i. e., the fiduciary that caused the plan to engage in the transaction.
But this
reductio ad absurdum
ignores the limiting principle explicit in § 502(a)(3): that the retrospective relief sought be “appropriate equitable relief.” The common law of trusts, which offers a “starting point for analysis [of ERISA] . . . [unless] it is inconsistent with the language of the statute, its structure, or its purposes,”

v.
Jacobson,
“Whenever the legal title to property is obtained through means or under circumstances ‘which render it uneonseientious for the holder of the legal title to retain and enjoy the beneficial interest, equity impresses a constructive trust on the property thus acquired in favor of *251 the one who is truly and equitably entitled to the same, although he may never, perhaps, have had any legal estate therein; and a court of equity has jurisdiction to reach the property either in the hands of the original wrongdoer, or in the hands of any subsequent holder, until a purchaser of it in good faith and without notice acquires a higher right and takes the property relieved from the trust.’ ” Moore v. Crawford,130 U. S. 122 ,128 (1889) (quoting 2 J. Pomeroy, Equity Jurisprudence § 1053, pp. 628-629 (1886)).
Importantly, that a transferee was not “the original wrongdoer” does not insulate him from liability for restitution. See also,
e. g.,
Restatement of Restitution ch. 7, Introductory Note, p. 522 (1937); 1 Dobbs,
supra,
§4.3(2), at 597 (“The constructive trust is based on property, not wrongs”). It also bears emphasis that the common law of trusts sets limits on restitution actions against defendants other than the principal “wrongdoer.” Only a transferee of ill-gotten trust assets may be held liable, and then only when the transferee (assuming he has purchased for value) knew or should have known of the existence of the trust and the circumstances that rendered the transfer in breach of the trust. Translated to the instant context, the transferee must be demonstrated to have had actual or constructive knowledge of the circumstances that rendered the transaction unlawful. Those circumstances, in turn, involve a showing that the
plan fiduciary,
with actual or constructive knowledge of the facts satisfying the elements of a § 406(a) transaction, caused the plan to engage in the transaction.
Lockheed Corp.
v.
Spink,
*252 The common law additionally leads us to reject Salomon’s complaint that our view of § 502(a)(3) would incongruously allow not only the harmed beneficiaries, but also the culpable fiduciary, to seek restitution from the arguably less culpable counterparty-transferee. The common law sees no incongruity in such a rule, see Restatement (Second) of Trusts, supra, §294, at 69 (“[A]n action can be maintained against the transferee either by the beneficiary or the trustee”); 4 Law of Trusts §294.2, at 101, and for good reason: “Although the trustee bases his cause of action upon his own voluntary act, and even though the act was knowingly done in breach of his duty to the beneficiary, he is permitted to maintain the action, sinee the purpose of the action is to recover money or other property for the trust estate, and whatever he recovers he will hold subject to the trust.” Restatement (Second) of Trusts, supra, §294, Comment c.
But Salomon advances a more fundamental critique of the common-law analogy, reasoning that the antecedent violation here — a violation of § 406(a)’s
per se
prohibitions on transacting with a party in interest — was unknown at common law, and that common-law
liability
should not attach to an act that does not violate a common-law
duty.
While Salomon accurately characterizes § 406(a) as expanding upon the common law’s arm’s-length standard of conduct, see
Keystone Consol. Industries,
We note, however, that our interpretation of § 502(a)(3) to incorporate common-law remedial principles does not necessarily foreclose accommodation of Salomon’s underlying concern that ERISA should not be construed to require counter-parties to transactions with a plan to monitor the plan for compliance with each of ERISA’s intricate details. See, e. g., Prohibited Transaction Exemption 75-1, § 11(e), 40 Fed. Reg. 50847 (1975) (requiring that the plan maintain certain *253 records for a 6-year period). While we have no occasion to decide the matter here, it may be that such concerns should inform courts’ determinations of what a transferee should (or should not) be expected to know when engaging in a transaction with a fiduciary. See Restatement (Second) of Trusts § 297(a), at 74 (defining “notice” to mean what a transferee “knows or should know” (emphasis added)). Cf. Prohibited Transaction Exemption 75-1, § 11(e)(1), 40 Fed. Reg. 50847 (1975) (providing that a broker-dealer shall not be subject to civil penalties under §502(i) as a § 406(a) “party in interest” or taxes under 26 U. S. C. §4975 as a similarly defined “disqualified person” if such records are not maintained by the plan).
For these reasons, an action for restitution against a transferee of tainted plan assets satisfies the “appropriate[ness]” criterion in § 502(a)(3). Such relief is also “equitable” in nature. See
Mertens,
IV
We turn, finally, to two nontextual clues cited by Salomon and
amici.
First, Salomon urges us to consider, as the Seventh Circuit did,
We decline these suggestions to depart from the text of § 502(a)(3). In ERISA cases, “[a]s in any case of statutory construction, our analysis begins with the language of the statute. . . . And where the statutory language provides a clear answer, it ends there as well.”
Hughes Aircraft,
Accordingly, we reverse the Seventh Circuit’s judgment and remand the ease for further proceedings consistent with this opinion.-
It is so ordered.
Notes
Salomon has preserved for remand arguments that there is no § 406(a) prohibition because it is not a “party in interest” and that, in any event, the transaction is exempted by Prohibited Transaction Exemption 75-1, 40 Fed. Reg. 50847 (1975).
Salomon asserts that petitioners waived this theory by neglecting to present it to the courts below. According to Salomon, petitioners’ claim (until their merits brief in this Court) has been that Salomon may be sued under § 502(a)(3) only because Salomon “violated” § 406(a). But, even assuming that petitioners did not pellucidly articulate this theory before the Seventh Circuit, it appears to us that the Seventh Circuit understood the tenor of the argument — namely, that the §406(a) transaction is the “act or practice” which violates §406(a) and therefore may be redressed by a civil action brought under § 502(a)(3) against parties to the § 406(a) transaction, even if the defendant did not itself “violate” § 406(a). See
The issue of which party, as between the party seeking recovery and the defendant-transferee, bears the burden of proof on whether the transferee is a purchaser for value and without notice, is not currently before us, but may require resolution on remand. Cf 4 Law of Trusts §284, at 40 (noting conflict of authority in non-ERISA cases on which party bears the burden of proof).
