Majority — Scalia J.
delivered the opinion of the Court.
We consider whether the 2-year period to file suit against a corporate insider under § 16(b) of the Securities Exchange Act of 1934, 15 U. S. C. § 78p(b), begins to run only upon the
I
Under § 16(b) of the Exchange Act, 48 Stat. 896 , as amended, a corporation or security holder of that corporation may bring suit against the officers, directors, and certain beneficial owners[1] of the corporation who realize any profits from the purchase and sale, or sale and purchase, of the corporation’s securities within any 6-month period. “The statute imposes a form of strict liability” and requires insiders to disgorge these “short-swing” profits “even if they did not trade on inside information or intend to profit on the basis of such information.” Gollust v. Mendell, 501 U. S. 115 , 122 (1991). Section 16(b) provides that suits must be brought within “two years after the date such profit was realized.”[2] 15 U. S. C. § 78p(b).
1 Section 16(b) regulates beneficial owners of more than 10% of any class of equity securities. 15 U. S. C. § 78p(a)(l).
2 Section 16(b) provides in full: “For the purpose of preventing the unfair use of information which may have been obtained by such beneficial owner, director, or officer by reason of his relationship to the issuer, any profit realized by him from any purchase and sale, or any sale and purchase, of any equity security of such issuer (other than an exempted security) or a security-based swap agreement (as defined in section 206B of the Gramm-Leach-Bliley Act) involving any such equity security within any period of less than six months, unless such security or security-based swap agreement was acquired in good faith in connection with a debt previously contracted, shall inure to and be recoverable by the issuer, irrespective of any intention on the part of such beneficial owner, director, or officer in entering into such transaction of holding the security or security-based swap agreement purchased or of not repurchasing the security or security-based swap agreement sold for a period exceeding six months. Suit to recover such profit may be instituted at law or in equity in any court of competent jurisdiction by the issuer, or by the owner of any security of the issuer in the name and in behalf of the issuer if the issuer shall fail or refuse to bring such suit within sixty days after request or shall fail diligently to prosecute the same thereafter; but no such suit shall be brought more than two years after the date such profit was realized. This subsection shall not be con *224 strued to cover any transaction where such beneficial owner was not such both at the time of the purchase and sale, or the sale and purchase, of the security or security-based swap agreement (as defined in section 206B of the Gramm-Leach-Bliley Act) involved, or any transaction or transactions which the [Securities and Exchange] Commission by rules and regulations may exempt as not comprehended within the purpose of this subsection.” 15 U.S. C. § 78p(b).
3 Simmonds also named the issuing companies as nominal defendants. In re: Section 16(b) Litigation, 602 F. Supp. 2d 1202 , 1204 (WD Wash. 2009).
4 Petitioners have consistently disputed §16’s application to them, arguing that they, as underwriters, are generally exempt from the statute’s coverage. See 17 CFR §§240 .16a-7(a) and 240.16a-10. Simmonds contends that this exemption does not apply where the underwriters do not act in good faith. Brief for Respondent 49. See §240.16a-7(a). We express no view on this issue.
II
Petitioners maintain that these suits were properly dismissed because they were filed more than, two years after the alleged profits were realized. Pointing to dictum in Lampf, Pleva, Lipkind, Prupis & Petigrow v. Gilbertson, 501 U. S. 350 (1991), petitioners argue that § 16(b)’s limitations period is a period of repose, which is not to be “extended to account for a plaintiff’s discovery of the facts underlying a claim.” Brief for Petitioners 17. See Lampf, supra, at 360, n. 5 (“Section 16(b)... sets a 2-year ... period of repose”). We do not reach that contention, because we conclude that, even assuming that the 2-year period can be extended, the Ninth Circuit erred in determining that it is tolled until the filing of a § 16(a) statement.
5 Simmonds voluntarily dismissed one of the complaints. 602 F. Supp. 2d, at 1206, n. 4 .
The Whittaker court suggested that the background rule of equitable tolling for fraudulent concealment[6] operates to toll the limitations period until the § 16(a) statement is filed. See 639 F. 2d, at 527 , and n. 9. Even accepting that equitable tolling for fraudulent concealment is triggered by the
6 Relying on our decision in American Pipe & Constr. Co. v. Utah, 414 U. S. 538 (1974), Simmonds argues that the Whittaker rule is best understood as applying legal — rather than equitable — tolling. In American Pipe, we held that “commencement of a class action suspends the applicable statute of limitations as to all asserted members of the class who would have been parties had the suit been permitted to continue as a class action.” 414 U. S., at 554 . We based our conclusion on “the efficiency and economy of litigation which is a principal purpose of [Fed. Rule Civ. Proc. 23 class actions).” Id., at 553 . Although we did not employ the term “legal tolling,” some federal courts have used that term to describe our holding on the ground that the rule “is derived from a statutory source,” whereas equitable tolling is “judicially created.” Arivella v. Lucent Technologies, Inc., 623 F. Supp. 2d 164 , 176 (Mass. 2009). The label attached to the Whittaker rule does not matter. As we proceed to explain, neither general equitable-tolling principles nor the “statutory source” of § 16 supports the conclusion that the limitations period is tolled until the filing of a § 16(a) statement.
The inequity of the Whittaker rule is especially apparent in a case such as this, where the theory of § 16(b) liability of underwriters is so novel that petitioners can plausibly claim that they were not aware they were required to file a § 16(a) statement. And where they disclaim the necessity of filing, the Whittaker rule compels them either to file or to face the prospect of § 16(b) litigation in perpetuity. Simmonds has acknowledged that “under her theory she could buy stocks in companies who had IPOs 20 years ago and bring claims for short-swing transactions if the underwriters had undervalued a stock.” 602 F. Supp. 2d, at 1218 . The potential for such endless tolling in cases in which a reasonably diligent plaintiff would know of the facts underlying the
Simmonds maintains that failing to apply the Whittaker rule would obstruct Congress’s objective of curbing short-swing speculation by corporate insiders. This objective, according to Simmonds, is served by § 16(a) statements, which “provide the information necessary to trigger § 16(b) enforcement.” Brief for Respondent 24. Simmonds — like the Ninth Circuit in Whittaker — disregards the most glaring indication that Congress did not intend that the limitations period be categorically tolled until the statement is filed: The limitations provision does not say so. This fact alone is reason enough to reject a departure from settled equitable-tolling principles. Moreover, § 16⅛ purpose is fully served by the rules outlined above, under which the limitations period would not expire until two years after a reasonably diligent plaintiff would have learned the facts underlying a § 16(b) action. The usual equitable-tolling inquiry will thus take account of the unavailability of sources of information other than the § 16(a) filing. Cf., e. g., Ruth v. Unifund CCR Partners, 604 F. 3d 908 , 911-913 (CA6 2010); Santos ex rel. Beato v. United States, 559 F. 3d 189 , 202-203 (CA3 2009). The oddity of Simmonds’ position is well demonstrated by the circumstances of this case. Under the Whittaker rule, because petitioners have yet to file § 16(a) statements (as noted earlier they do not think themselves subject to that requirement), Simmonds still has two years to bring suit, even though she is so well aware of her alleged cause of action that she has already sued. If § 16(a) statements were, as Simmonds suggests, indispensable to a party’s ability to sue, Simmonds would not be here.
Simmonds also asserts that application of established equitable-tolling doctrine in this context would be inconsist

Having determined that § 16(b)’s limitations period is not tolled until the filing of a § 16(a) statement, we remand for the lower courts to consider how the usual rules of equitable tolling apply to the facts of this case.[8] We are divided 4 to
7 It is for this reason that we also reject the Second Circuit’s rule that the 2-year period is tolled until the plaintiff “gets actual notice that a person subject to Section 16(a) has realized specific short-swing profits that are worth pursuing,” Litzler v. CC Investments, L. D. C., 362 F. 3d 203 , 208 (2004). As that court itself recognized, this actual-notice rule departs from usual equitable-tolling principles. See id., at 207 .
8 The District Court said that “there is no dispute that all of the facts giving rise to Ms. Simmonds’ complaints against [petitioners] were known to the shareholders of the Issuer Defendants for at least five years before these cases were filed,” 602 F. Supp. 2d, at 1217 . The Court of Appeals did not consider the accuracy of that statement, which Simmonds disputes, Brief for Respondent 12, since it concluded the period is tolled until a § 16(a) statement is filed.
It is so ordered.
The Chief Justice took no part in the consideration or decision of this case.
