JOSÉ A. CABRANES, Circuit Judge:
This appeal presents an unsettled question of law: whether the tolling rule set forth by the Supreme Court in American Pipe & Construction Co. v. Utah, 414 U.S. 538, 94 S.Ct. 756, 38 L.Ed.2d 713 (1974) ("American Pipe") — that "the 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," id. at 554, 94 S.Ct. 756 — applies to the three-year statute of repose in Section 13 of the Securities Act of 1933 ("Securities Act"), 15 U.S.C. § 77m.1 In addition, we are called upon to decide whether non-party members of a putative class can avoid the effect of a statute of repose using the "relation back" doctrine of Federal Rule of Civil Procedure 15(c) to amend the class complaint and intervene in the action as named parties.2
This appeal comes to us from an order of the United States District Court for the Southern District of New York (Lewis A. Kaplan, Judge) denying, in relevant part, proposed intervenors-appellants' motions to intervene.3 See In re IndyMac Mortgage-Backed Sec. Lit., 793 F.Supp.2d 637 (S.D.N.Y.2011) ("IndyMac II"). The lead plaintiff and other putative class members alleged that defendants had made fraudulent misrepresentations and omissions in the offering and sale of certain financial instruments which they purchased. Following the District Court's dismissal of certain claims, as well as the expiration of the three-year statute of repose under Section 13, several putative class members sought to intervene in the action to revive the dismissed claims on either of two theories: (1) that the American Pipe tolling rule operated to preserve their right to sue, or (2) that Rule 15(c) of the Federal Rules of Civil Procedure allowed them to "relate back" their otherwise untimely claims to the surviving claims in the class complaint. The District Court rejected these two theories and denied the motions to intervene as barred under Section 13's statute of repose. This appeal by proposed intervenors-appellants followed.
We hold that: (1) American Pipe's tolling rule does not apply to the three-year statute of repose in Section 13; and (2) absent circumstances that would render the newly asserted claims independently timely, neither Federal Rule of Civil Procedure 24 nor the Rule 15(c) "relation back" doctrine permits members of a putative class, who are not named parties, to intervene in the class action as named parties in order to revive claims that were dismissed from the class complaint for want of jurisdiction. In practical terms, the proposed intervenors may not circumvent Section 13's statute of repose by invoking American Pipe or Rule 15(c). Accordingly, we AFFIRM the June 21, 2011 order of the District Court, insofar as it partially denied motions to intervene by the proposed intervenors.
I. BACKGROUND
This appeal arises from two securities class actions, consolidated by the District Court, asserting claims for violations of Sections 11, 12(a) and 15 of the Securities Act4 against IndyMac MBS, Inc. ("IndyMac MBS"), an issuer of mortgage-backed securities, and certain of its officers, directors, and underwriters (jointly, "defendants"). As relevant here, IndyMac MBS issued securities known as mortgage pass-through certificates ("Certificates") "in 106 different offerings pursuant to three registration statements and the related prospectuses and prospectus supplements."5 In re IndyMac, 718 F.Supp.2d 495, 498 (S.D.N.Y.2010) ("IndyMac I"). The Police and Fire Retirement System of the City of Detroit ("Detroit PFRS") and the Wyoming State Treasurer and the Wyoming Retirement System (jointly, "Wyoming" or "Wyoming entities") commenced two separate putative class actions against the IndyMac defendants on behalf of asserted class members who had purchased Certificates in some of the 106 offerings. The District Court then consolidated the Detroit PFRS and Wyoming actions, and appointed Wyoming lead plaintiff of the consolidated action, pursuant to the Private Securities Litigation Reform Act ("PSLRA"), 15 U.S.C. § 78u-4.6 Although Wyoming was the only plaintiff named in the consolidated action, the Amended Consolidated Complaint ("Amended Complaint") raised claims on behalf of other asserted class members, who were purchasers of the IndyMac Certificates.
On June 21, 2010, the District Court dismissed for lack of standing all claims in the Amended Complaint arising from the offerings of securities not purchased by the Wyoming entities, who are the lead and sole named plaintiffs. IndyMac I, 718 F.Supp.2d at 501. The District Court explained that, as in any lawsuit, the named plaintiffs must demonstrate constitutional standing, and that the Wyoming entities had failed to make the necessary showing of injury as to the offerings of securities that they did not purchase. Id. (relying on an earlier District Court opinion in separate mortgage-backed securities litigation).
The dismissed claims included those involving securities purchased by Detroit PFRS and by other members of the asserted class, none of whom were named plaintiffs. In addition to Detroit PFRS, five members of the asserted class — (1) the City of Philadelphia Board of Pensions and Retirement ("Philadelphia"); (2) the Los Angeles County Employees Retirement Association ("LACERA"); (3) the Public Employees' Retirement System of Mississippi ("PERS"); (4) the Iowa Public Employees' Retirement System ("Iowa"); and (5) the General Retirement System of the City of Detroit ("Detroit Retirement") — subsequently moved to intervene in the action, pursuant to Federal Rule of Civil Procedure 24,7 to assert claims with respect to the Certificates that those entities had purchased, but which the named Wyoming plaintiffs had not purchased.8 Although the three-year period of repose in Section 13 had run on their claims, these putative plaintiffs invoked the tolling rule set forth in American Pipe, where, as noted above, the Supreme Court held that "the 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, 94 S.Ct. 756 (emphasis supplied). The putative plaintiffs argued that the American Pipe tolling rule, which has long been accepted in the context of statutes of limitations, applied equally to the statute of repose in Section 13. The putative plaintiffs further argued that, in the event that American Pipe tolling did not apply, it could nonetheless "relate back" its proposed amended complaint to the Amended Complaint by operation of Federal Rule of Civil Procedure Rule 15(c), see note 2, ante, despite the expiration of the three-year period for bringing these claims.
The District Court denied the motions to intervene in a thorough and careful memorandum opinion of June 21, 2011, reasoning that the Section 13 repose period had expired and could not be tolled under American Pipe or extended by operation of Rule 15(c). See Indymac II, 793 F.Supp.2d 637. Three of the five putative plaintiffs — Detroit Retirement, LACERA, and PERS — filed a notice of appeal as proposed intervenors to this Court on July 20, 2011.9
II. DISCUSSION
A. Standards of Review
We review de novo a district court's denial of a motion to dismiss, see, e.g., Gollomp v. Spitzer, 568 F.3d 355, 365 (2d Cir.2009), and its denial of a motion to intervene for an "abuse of discretion," AT & T Corp. v. Sprint Corp., 407 F.3d 560, 561 (2d Cir.2005). To the extent that our analysis requires us to review interpretations of a statute, we do so de novo. See United States v. Robles, 709 F.3d 98, 99 (2d Cir.2013) ("We review de novo a district court's decision resolving a question of statutory interpretation."); In re Sims, 534 F.3d 117, 132 (2d Cir.2008) ("A district court has abused its discretion if it based its ruling on an erroneous view of the law...." (alteration and internal quotation marks omitted)).
B. Legal Framework
i. American Pipe tolling
The principal issue before us is whether the tolling rule set forth by the Supreme Court in American Pipe and its progeny applies to the three-year statute of repose in Section 13 of the Securities Act. The plaintiffs in American Pipe originally instituted a timely putative class-action antitrust suit, which was dismissed by the district court in that case for failing to satisfy the prerequisite of "numerosity," as required for certification of a class under Rule 23(a)(1) of the Federal Rules of Civil Procedure.10 414 U.S. at 543, 94 S.Ct. 756. Soon after, the district court denied the motions to intervene — filed pursuant to Rule 24, see note 7, ante, by proposed members of the asserted class — on the ground that the applicable statute of limitations, Section 4B of the Clayton Act,11 had run during the pendency of the litigation. See American Pipe, 414 U.S. at 543-44, 94 S.Ct. 756.
The Court of Appeals for the Ninth Circuit reversed the district court's denial of the motions to intervene, concluding that the denial of class certification could not "strand" asserted members of the class for whom the statute of limitations had run while the case was pending. Id. at 544-45, 94 S.Ct. 756. The Supreme Court then affirmed the Ninth Circuit's decision, holding that "the 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." Id. at 554, 94 S.Ct. 756.
In reaching this conclusion, the American Pipe Court relied heavily on Rule 23, reasoning that a contrary holding would "frustrate the principal function of a class action" and create a "multiplicity of activity which Rule 23 was designed to avoid."12 Id. at 551, 94 S.Ct. 756; see also id. at 555, 94 S.Ct. 756 (suggesting that tolling derived from Court's "interpretation of the Rule"). The American Pipe Court, however, also seemed to rely on the equitable power of the courts to toll statutes of limitations. For instance, it observed that "[i]n recognizing judicial power to toll statutes of limitation in federal courts we are not breaking new ground." Id. at 558, 94 S.Ct. 756 (emphasis supplied); see also id. at 558 n. 29, 94 S.Ct. 756 (concluding that "judicial tolling of the statute of limitations does not abridge or modify a substantive right"). Ultimately, the American Pipe Court stated that "the tolling rule we establish here is consistent both with the procedures of Rule 23 and with the proper function of the limitations statute." Id. at 555, 94 S.Ct. 756.
In Crown, Cork & Seal Co. v. Parker, 462 U.S. 345, 103 S.Ct. 2392, 76 L.Ed.2d 628 (1983), the Supreme Court clarified that the American Pipe tolling rule applies not only to putative class members who seek to intervene in an action, but also to would-be class members who later file their own independent actions. Id. at 353-54, 103 S.Ct. 2392; see also Joseph v. Wiles, 223 F.3d 1155, 1167 (10th Cir.2000). In so doing, the Crown Court explained the rationale for the American Pipe tolling doctrine:
The American Pipe Court recognized that unless the statute of limitations was tolled by the filing of the class action, class members would not be able to rely on the existence of the suit to protect their rights. Only by intervening or taking other action prior to the running of the statute of limitations would they be able to ensure that their rights would not be lost in the event that class certification was denied.... [In the absence of tolling,] [a] putative class member who fears that class certification may be denied would have every incentive to file a separate action prior to the expiration of his own period of limitations. The result would be a needless multiplicity of actions — precisely the situation that Federal Rule of Civil Procedure 23 and the tolling rule of American Pipe were designed to avoid.
Crown, 462 U.S. at 350-51, 103 S.Ct. 2392.
Proposed intervenors in this appeal now seek to apply the tolling rule of American Pipe to the statute of repose provision in Section 13.
ii. Section 13 as a Statute of Repose
Although "[s]tatutes of repose and statutes of limitations are often confused[,]... they are [nonetheless] distinct" and serve distinct purposes. Ma v. Merrill Lynch, Pierce, Fenner & Smith, Inc., 597 F.3d 84, 88 n. 4 (2d Cir.2010); see also City of Pontiac Gen. Emps.' Ret. Sys. v. MBIA, Inc., 637 F.3d 169, 175 (2d Cir. 2011) (noting a difference in the "basic purpose" of a statute of limitations as contrasted to a statute of repose). As we recently explained:
Statutes of limitations limit the availability of remedies and, accordingly, may be subject to equitable considerations, such as tolling, or a discovery rule. In contrast, statutes of repose affect the underlying right, not just the remedy, and thus they run without interruption once the necessary triggering event has occurred, even if equitable considerations would warrant tolling or even if the plaintiff has not yet, or could not yet have, discovered that she has a cause of action.
Fed. Hous. Fin. Agency v. UBS Americas Inc., 712 F.3d 136, 140 (2d Cir.2013) (internal citations and quotation marks omitted). In other words, while statutes of limitations are "often subject to tolling principles," a statute of repose "extinguishes a plaintiff's cause of action after the passage of a fixed period of time, usually measured from one of the defendant's acts." Ma, 597 F.3d at 88 n. 4.
Thus, in contrast to statutes of limitations, statutes of repose "create[ ] a substantive right in those protected to be free from liability after a legislatively-determined period of time." Amoco Prod. Co. v. Newton Sheep Co., 85 F.3d 1464, 1472 (10th Cir.1996) (emphasis supplied) (quotation marks omitted); see also P. Stolz Family P'ship. L.P. v. Daum, 355 F.3d 92, 102 (2d Cir.2004) ("Stolz") ("Unlike a statute of limitations, a statute of repose is not a limitation of a plaintiff's remedy, but rather defines the right involved in terms of the time allowed to bring suit."). This conceptual distinction carries significant practical consequences. For instance, "a statute of repose may bar a claim even before the plaintiff suffers injury, leaving her without any remedy." Fed. Hous. Fin. Agency, 712 F.3d at 140 (emphasis supplied) (relying on Stolz, 355 F.3d at 103, and Stuart, 158 F.3d at 627); see also McCann v. Hy-Vee, Inc., 663 F.3d 926, 930 (7th Cir.2011). And, as most important here, a statute of repose is "subject [only] to legislatively created exceptions," Stolz, 355 F.3d at 102 (quotation marks omitted), and not to equitable tolling, Fed. Hous. Fin. Agency, 712 F.3d at 140 (internal alterations omitted).
Section 13 of the Securities Act contains two limitations periods.13 See note 1, ante. The first — a statute of limitations — states, in relevant part, that "[n]o action shall be maintained to enforce any liability ... unless brought within one year after the discovery of the untrue statement or the omission, or after such discovery should have been made by the exercise of reasonable diligence, or ... within one year after the violation upon which it is based." 15 U.S.C. § 77m. As relevant here, the second limitations period of Section 13 — a statute of repose — states that "[i]n no event shall any such action be brought to enforce a liability ... more than three years after the [underlying] security was bona fide offered to the public, or ... more than three years after [its] sale." Id.
Courts have repeatedly recognized that the three-year limitations period in Section 13 is a statute of repose. See, e.g., Lampf, Pleva, Lipkind, Prupis & Petigrow v. Gilbertson, 501 U.S. 350, 360, 362, 111 S.Ct. 2773, 115 L.Ed.2d 321 (1991) ("Lampf") (referring to Section 13 as a "3-year period of repose"); Fed. Hous. Fin. Agency, 712 F.3d at 140; Stolz, 355 F.3d at 96. In so doing, they have also emphasized that, as a statute of repose, the three-year period in Section 13 is said to be "absolute" and not subject to equitable tolling. For instance, the Supreme Court in Lampf noted that Section 13's three-year limitation "is a period of repose inconsistent with tolling," and reiterated that the "purpose of the 3-year limitation is clearly to serve as a cutoff," to which "tolling principles" do not apply. Lampf, 501 U.S. at 363, 111 S.Ct. 2773 (emphasis supplied). We have similarly recognized that "a statute of repose begins to run without interruption once the necessary triggering event has occurred, even if equitable considerations would warrant tolling or even if the plaintiff has not yet, or could not yet have, discovered that she has a cause of action." Stolz, 355 F.3d. at 102-03; see also Jackson Nat'l Life Ins. Co. v. Merrill Lynch & Co., 32 F.3d 697, 704 (2d Cir.1994) ("The three-year period is an absolute limitation which applies whether or not the investor could have discovered the violation." (emphasis supplied)); see generally 2 T. Hazen, Law of Securities Regulation § 7.10[4] (6th ed. 2011) ("Section 13 is not only a statute of limitations but also operates as a statute of repose. There is an absolute maximum of three years in order to prevent stale claims. The three-year repose period is absolute in that it cannot be extended by applying equitable tolling principles.").
C. Application of American Pipe to Section 13's Statute of Repose
The Supreme Court's opinion in American Pipe does not explicitly state whether the Court was recognizing "judicial tolling," grounded in principles of equity, or statutory tolling (or, "legal" tolling), based on Rule 23.14 See Credit Suisse Sec. (USA) LLC v. Simmonds, ___ U.S. ___, 132 S.Ct. 1414, 1419 n. 6, 182 L.Ed.2d 446 (2012) (noting that "[a]lthough [American Pipe] 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'"). Judicial power to toll statutes of limitations arises from an "exercise of a court's equity powers," traditionally used to "relieve hardships which, from time to time, arise from a hard and fast adherence to more absolute legal rules." Holland v. Florida, ___ U.S. ___, 130 S.Ct. 2549, 2563, 177 L.Ed.2d 130 (2010) (internal quotation marks omitted). On the other hand, statutory tolling, as the name suggests, derives from a statutory, or "legal," source. See Credit Suisse Sec., 132 S.Ct. at 1419 n. 6; see also Albano v. Shea Homes Ltd. P'ship., 634 F.3d 524, 536 (9th Cir.2011). The parties make much of this distinction because, as explained above, if American Pipe's tolling rule is "equitable" in nature, it does not apply to statutes of repose, whereas if it is statutory or "legal" in nature, it may.
As discussed in Part II.B.i, ante, the American Pipe decision contains conflicting indications of the source of authority for its tolling rule, and the Supreme Court's subsequent statements on the matter — all in dicta — provide little clarity.15 The Courts of Appeals are divided on this issue. See Albano, 634 F.3d at 535 ("Among the issues on which there is no consensus is whether American Pipe tolling should be characterized as a legal tolling doctrine or as an equitable one."); compare Bright v. United States, 603 F.3d 1273, 1282, 1285-86 (Fed.Cir.2010) (describing American Pipe as "statutory" tolling), and Joseph, 223 F.3d at 1167 (10th Cir.) ("legal" tolling), with Bridges v. Dep't. of Md. State Police, 441 F.3d 197, 211 (4th Cir.2006) ("The American Pipe/ Crown, Cork & Seal equitable tolling rule is a limited exception to the universal rule that statutes of limitations are impervious to equitable exceptions."), and Veltri v. Bldg. Serv. 32B-J Pension Fund, 393 F.3d 318, 322-23 (2d Cir.2004) (referring, in dicta, to American Pipe as an instance where "equitable tolling has been held appropriate"). Experienced and capable judges of the district courts in our Circuit have similarly drawn disparate conclusions and are without consensus.16
But we need not try to divine any hidden meanings in American Pipe. If its tolling rule is properly classified as "equitable," then application of the rule to Section 13's three-year repose period is barred by Lampf, which states that equitable "tolling principles do not apply to that period." 501 U.S. at 363, 111 S.Ct. 2773. Even assuming, arguendo, that the American Pipe tolling rule is "legal" — based upon Rule 23, which governs class actions — we nonetheless hold that its extension to the statute of repose in Section 13 would be barred by the Rules Enabling Act, 28 U.S.C. § 2072(b). The Rules Enabling Act provides the Supreme Court "the power to prescribe general rules of practice and procedure," id. § 2072(a), including the Federal Rules of Civil Procedure, which "shall not abridge, enlarge or modify any substantive right," id. § 2072(b). The use of the term "shall" in the statute's language indicates its mandatory nature; federal courts are bound by its dictates, including in the context of Rule 23. Accordingly, "the Rules Enabling Act forbids interpreting Rule 23 to `abridge, enlarge or modify any substantive right,'" Wal-Mart Stores, Inc. v. Dukes, ___ U.S. ___, 131 S.Ct. 2541, 2561, 180 L.Ed.2d 374 (2011) (quoting 28 U.S.C. § 2072(b)), and "underscores the need for caution[,] ... counsel[ing] against adventurous application of" the Rule, Ortiz v. Fibreboard Corp., 527 U.S. 815, 845, 119 S.Ct. 2295, 144 L.Ed.2d 715 (1999).
As we have explained above, see Part II.B.ii, ante, the statute of repose in Section 13 creates a substantive right, extinguishing claims after a three-year period. Permitting a plaintiff to file a complaint or intervene after the repose period set forth in Section 13 of the Securities Act has run would therefore necessarily enlarge or modify a substantive right and violate the Rules Enabling Act.17 Accordingly, our conclusion is straightforward: American Pipe's tolling rule, whether grounded in equitable authority or on Rule 23, does not extend to the statute of repose in Section 13.
We are cautioned by some of the proposed intervenors that a failure to extend American Pipe tolling to the statute of repose in Section 13 could burden the courts and disrupt the functioning of class action litigation. See Joint Br. and Special App'x for Proposed Intervenors-Appellants LACERA and PERS at 42-43. We are not persuaded. Given the sophisticated, well-counseled litigants involved in securities fraud class actions, it is not apparent that such adverse consequences will inevitably follow our holding. See, e.g., Footbridge Ltd. Trust v. Countrywide Fin. Corp., 770 F.Supp.2d 618, 627 (S.D.N.Y. 2011) ("Even without lengthening the repose period, many class actions are resolved or reach the certification stage within the repose period."). But even if the decision causes some such problem, it is a problem that only Congress can address; judges may not deploy equity to avert the negative effects of statutes of repose.
D. Rule 15 ("Relation Back") in IndyMac
We now turn to the related, but distinct, question of whether the three proposed intervenors — Detroit Retirement, LACERA, and PERS — may intervene to bring certain claims despite the Section 13 statute of repose and the absence of any currently named plaintiff with standing to bring the same claims. In particular, we consider whether the proposed intervenors may "relate back" their proposed amended complaint to a prior, timely complaint pursuant to Rule 15(c).18 See Part I, ante.
In this case, the statute of repose in Section 13 ordinarily bars the commencement of any new suits after the three-year period has expired. Accordingly, we proceed to consider only whether proposed intervenors may, as asserted class members in the original complaint, press their otherwise expired claims using Rule 15(c). For the reasons discussed below, we hold that the Rule 15(c) "relation back" doctrine does not permit members of a putative class, who are not named parties, to intervene in the class action as named parties in order to revive claims that were dismissed from the class complaint for want of jurisdiction.
In analyzing the proposed intervenors' Rule 15(c) argument, we reiterate at the outset that after the District Court consolidated the Detroit PFRS and Wyoming actions, pursuant to the PSLRA, 15 U.S.C. § 78u-4, see note 6, ante, and appointed Wyoming to be the lead plaintiff of the consolidated action, no other plaintiffs were named in the consolidated action. The District Court subsequently dismissed for lack of standing all claims in the Amended Complaint arising from any offerings in which the Wyoming entities, as the lead and sole named plaintiffs, had not themselves purchased securities. IndyMac I, 718 F.Supp.2d at 501; see also In re Initial Pub. Offering Sec. Litig., 214 F.R.D. 117, 122 (S.D.N.Y.2002) ("[C]ourts in this circuit have repeatedly held that, in order to maintain a class action, Plaintiffs must first establish that they have a valid claim with respect to the shares that they purchased." (alterations omitted) (emphasis supplied)).19 Notably, Detroit Retirement, LACERA, and PERS — the three proposed intervenors who are appellants here — were, at all times, members of the asserted class in the consolidated action, but were never named plaintiffs. Thus, as class members, these putative intervenors were represented vicariously but were not litigants themselves.
In these circumstances, the proposed intervenors' ability to join the suit is foreclosed by the "long recognized" rule that "if jurisdiction is lacking at the commencement of a suit, it cannot be aided by the intervention of a plaintiff with a sufficient claim." Disability Advocates, Inc. v. N.Y. Coal. for Quality Assisted Living, Inc., 675 F.3d 149, 160 (2d Cir. 2012) (internal quotation marks and alterations omitted); see also Town of West Hartford v. Operation Rescue, 915 F.2d 92, 95 (2d Cir.1990) ("[I]t is fundamental that an intervening claim cannot confer subject matter jurisdiction over the action it seeks to join."); 7C C. Wright, A. Miller, & M. Kane, Federal Practice and Procedure § 1917, at 457 (3d ed. 2005) ("Intervention cannot cure any jurisdictional defect that would have barred the federal court from hearing the original action.").20
Prior to class certification, the District Court dismissed for lack of constitutional standing all claims in the Amended Complaint arising from offerings that the Wyoming entities, as the only named plaintiffs, had not purchased. In so doing, the District Court ruled that no named plaintiff in the suit had constitutional standing to bring the claims that the proposed intervenors later sought to assert before the District Court and which they now press on appeal.21 The District Court lacked jurisdiction over certain claims of the original lead plaintiff — the very claims now asserted by the proposed intervenors — and that defect may not be cured by later intervention. See Disability Advocates, 675 F.3d at 160. Accordingly, absent circumstances that would render the newly asserted claims independently timely, neither Rule 24 nor the Rule 15(c) "relation back" doctrine permits members of a putative class, who are not named parties, to intervene in the class action as named parties in order to revive claims that were dismissed from the class complaint for want of jurisdiction.22
Our holding here is consistent with the structure and purposes of the PSLRA. That statute provides that a district court should appoint as lead plaintiff "the member or members of the purported plaintiff class that [are] most capable of adequately representing the interests of class members." 15 U.S.C. § 78u-4(a)(3)(B)(i); 15 U.S.C. § 77z-1(a)(3)(B)(i). However, "[n]othing in the PSLRA indicates that district courts must choose a lead plaintiff with standing to sue on every available cause of action.... [I]t is inevitable that, in some cases, the lead plaintiff will not have standing to sue on every claim." Hevesi v. Citigroup Inc., 366 F.3d 70, 82 (2d Cir.2004). Nor do we think it necessary "that a different lead plaintiff be appointed to bring every single available claim," as such a requirement "would contravene the main purpose of having a lead plaintiff — namely, to empower one or several investors with a major stake in the litigation to exercise control over the litigation as a whole." Id. at 82 n. 13. Rather, there must be a named plaintiff sufficient to establish jurisdiction over each claim advanced. See id. at 82-83.
Our holding today merely reemphasizes that "the [PSLRA] was ... certainly not intended to excuse sophisticated parties [such as proposed intervenors] from being diligent and keeping abreast of developments in the case, especially when the class is not certified." Emp'rs-Teamsters Local Nos. 175 & 505 Pension Trust Fund v. Anchor Capital Advisors, 498 F.3d 920, 925 (9th Cir.2007). The proposed intervenors, through minimal diligence, could have avoided the operation of the Section 13 statute of repose simply by making timely motions to intervene in the action as named plaintiffs, or by filing their own timely actions and, if prudent, seeking to join their claims under Federal Rule of Civil Procedure 20 (joinder).23
CONCLUSION
To summarize, we hold that:
(1) The tolling rule set forth by the Supreme Court in American Pipe & Construction Co. v. Utah, 414 U.S. 538, 94 S.Ct. 756, 38 L.Ed.2d 713 (1974), does not apply to the three-year statute of repose in Section 13 of the Securities Act of 1933, 15 U.S.C.A. § 77m; and
(2) Absent circumstances that would render the newly asserted claims independently timely, neither Rule 24 nor the Rule 15(c) "relation back" doctrine permits members of a putative class, who are not named parties, to intervene in the class action as named parties in order to revive claims that were dismissed from the class complaint for want of jurisdiction.
For these reasons, we AFFIRM the June 21, 2011 order of the District Court, insofar as it partially denied the motions to intervene by proposed intervenors.
