This appeal requires us once again to grapple with the aftermath of the Ponzi scheme run by Bernard L. Madoff. Defendants-Appellants Pricewaterhouse-Coopers and Citco2 (collectively, the “Non-Settling Defendants”) seek to overturn a partial final judgment entered in the United States District Court for the Southern District of New York (Marrero, J.) approving the settlement of certain putative class action claims. The settled claims were brought by Plaintiffs-Appel-lees (the “Investor Plaintiffs”) who were individual and institutional investors in so-called Madoff feeder funds managed by the Fairfield Greenwich Group.3 The claims were brought against the Group as well as its directors and officers (collectively, the “Fairfield Greenwich Defendants” or the “Settling Defendants”).
The Non-Settling Defendants challenge one particular provision in the settlement agreement that provides that investors who file claims under the settlement submit to the district court’s jurisdiction for the sole purpose of participating in the settlement and not for any other purpose. The Non-Settling Defendants contend that the district court erred in approving this provision because district courts cannot permit litigants to agree to insulate themselves from personal jurisdiction if it would otherwise be created as a result of the settlement.
In response, the Investor Plaintiffs contend, among other things, that the Non-Settling Defendants lack standing to lodge this objection. The Non-Settling Defendants counter that they have standing because the provision in question prejudices their rights to assert that participation in the settlement should bar or limit investor claims against them in other litigation. Because we conclude that the Non-Set*216tling Defendants do not have standing to challenge the settlement, we dismiss the appeal.
I.
Plaintiffs-Appellees invested money in funds sponsored and managed by the Fair-field Greenwich Group, which in turn invested substantially all of its assets with Bernard L. Madoff Investment Securities LLC. After discovering that their investments were lost as a result of Madoffs fraudulent scheme, Investor Plaintiffs brought a putative class action asserting federal securities and state common law claims against the Fairfield Greenwich Defendants, their outside public accountants, PricewaterhouseCoopers, and Citco and GlobeOp Financial Services, LLC,4 which provided various professional services to the funds. In addition to restitution of the $5 billion Investor Plaintiffs alleged that they, as a class lost, as a result of Madoffs fraudulent scheme, the complaint sought consequential and punitive damages as well as disgorgement of profits purportedly obtained by the defendants.
Following protracted motion practice,5 the Investor Plaintiffs and the Fairfield Greenwich Defendants engaged in settlement negotiations and in November 2012 moved for the preliminary approval of a settlement they had reached. The settlement purported to resolve all claims between the Investor Plaintiffs and the Fair-field Greenwich Defendants.
As Plaintiffs’ motion for class certification had not been adjudicated,6 the proposed preliminary approval order defined a settlement class (the “Settlement Class”)7 and provided that its members had the right to request exclusion from the class. The proposed order also provided that those investors who wished to remain in the class could file proofs of claim in order to share in the distribution of the settlement proceeds.
Paragraph 17 of the proposed order further provided that Settlement Class members who filed proofs of claim would submit to the district court’s jurisdiction as follows:
Any Settlement Class Member who submits a Request for Exclusion or a Proof of Claim thereby submits to the jurisdiction of the Court with respect to the subject matter thereof and all determinations made by the Court thereon.
Joint App’x 311 ¶ 17.
Following the filing of the motion for preliminary approval of the settlement, the putative class representatives were ap*217proached by several putative Settlement Class members who expressed concern that, as foreign individuals and entities, participation in the Settlement Class could subject them to clawback actions in United States courts by Irving Picard, the SIPC Trustee for Bernard L. Madoff Investment Securities, LLC, and Kenneth Krys, the court-appointed Liquidator of Fairfield Sentry Ltd., seeking to recover monies they may have directly or indirectly received through the Fairfield Greenwich Group from Madoff. In response to these concerns, on the eve of the preliminary approval hearing, the settling parties submitted an amended proposed order purporting to limit the district court’s jurisdiction over Settlement Class members. Paragraph 17 of the preliminary approval order was amended to state in relevant part:
[A]ny Settlement Class Member who submits a Proof of Claim thereby submits to the jurisdiction of this Court with respect only to the subject matter of such Proof of Claim and all determinations made by this Court thereon and shall not be deemed to have submitted to the jurisdiction of this Court or of any court in the United States for any other matter on account of such submission.
Joint App’x 415 ¶ 17 (emphasis added).
At the hearing, the Non-Settling Defendants objected to the amended language on the ground that class members who submitted to the court’s jurisdiction in order to accept the terms of the settlement could not, at the same time, be permitted to limit the legal consequences of doing so. The Non-Settling Defendants contended that they were currently facing claims in litigation in the Netherlands and were entitled to argue that any entity that participated in the New York settlement could not pursue claims in any other jurisdiction. The district court overruled the objections and approved the amended preliminary settlement order.
Following the end of the notice period, the Investor Plaintiffs moved for final approval of the settlement. Over the objections of the Non-Settling Defendants, the district court entered the final order approving the settlement and entering partial final judgment with respect to Investor Plaintiffs’ claims against the Fairfield Greenwich Defendants (the “Final Order”). Paragraph 28 of the Final Order contained language identical to paragraph 17 of the amended preliminary order providing that Settlement Class members who submit proofs of claim only submit to the jurisdiction 26 of the district court with respect to the subject matter of the proof of 27 claim. Special App’x 13. This appeal followed.
II.
Plaintiffs contend that the Non-Settling Defendants do not have standing to appeal the Final Order. The question of standing is a “threshold determinant ] of the propriety of judicial intervention.” Warth v. Seldin, 422 U.S. 490, 518, 95 S.Ct. 2197, 45 L.Ed.2d 343 (1975). Although we generally review a district court’s approval of a settlement for abuse of discretion, McReynolds v. RichardsCantave, 588 F.3d 790, 800 (2d Cir.2009), we review de novo the issue of whether the Non-Settling Defendants have standing to bring this appeal, see Denney v. Deutsche Bank AG, 443 F.3d 253, 262 (2d Cir.2006); Shain v. Ellison, 356 F.3d 211, 214 (2d Cir.2004).
Over the years, the Supreme Court has articulated the standard by which the “irreducible constitutional minimum of standing” is established. Lexmark Int’l, Inc. v. Static Control Components, Inc., 572 U.S. -, 134 S.Ct. 1377, 1386, 188 L.Ed.2d 392 (2014) (quoting Lujan v. Defenders of Wildlife, 504 U.S. 555, 560, 112 *218S.Ct. 2130, 119 L.Ed.2d 351 (1992)). A party must have suffered an injury-in-fact, that is, the invasion of a “legally protected interest” in a manner that is “concrete and particularized” and “actual or imminent, not conjectural or hypothetical.” Lujan, 504 U.S. at 560, 112 S.Ct. 2130 (internal quotation marks omitted). Moreover, the injury must be “fairly traceable” to the alleged conduct and it must be likely that the injury will be redressed by a favorable decision. Id. at 560-61, 112 S.Ct. 2130.
The standing requirements ensure that judicial resources are “devoted to those disputes in which the parties have a concrete stake.” Friends of the Earth, Inc. v. Laidlaw Envtl. Servs., Inc., 528 U.S. 167, 191, 120 S.Ct. 693, 145 L.Ed.2d 610 (2000). Consequently, we have observed that a non-settling 28 defendant generally lacks standing to object to a court order 29 approving a partial settlement because a non-settling defendant is ordinarily not affected by such a settlement. Zupnick v. Fogel, 989 F.2d 93, 98 (2d Cir.1993). This rule advances the policy of encouraging the voluntary settlement of lawsuits. See id.; Waller v. Fin. Corp. of Am., 828 F.2d 579, 583 (9th Cir.1987).
However, there is a recognized exception to this general rule which permits a non-settling defendant to object where it can demonstrate that it will sustain some formal legal prejudice as a result of the settlement. Zupnick, 989 F.2d at 98; see also Smith v. Arthur Andersen LLP, 421 F.3d 989, 998 (9th Cir.2005); Weinman v. Fid. Capital Appreciation Fund (In re Integra Realty Res., Inc.), 262 F.3d 1089, 1102 (10th Cir.2001); In re Vitamins Antitrust Class Actions, 215 F.3d 26, 31 (D.C.Cir.2000); Eichenholtz v. Brennan, 52 F.3d 478, 482 (3d Cir.1995); Agretti v. ANR Freight Sys., Inc., 982 F.2d 242, 247-48 (7th Cir.1992).
? Non-Settling Defendants contend that paragraph 28 of the Final Order causes them such prejudice because it “effectively strips them of defenses against the settling plaintiffs in other fora, including defenses based on duplicative litigation and preclusion.” Brief of Defendants-Appellants (“App.Br”) at 11 (emphasis added). This allegation, however, does not rise to the required level of formal legal prejudice necessary for standing. That level exists only in those rare circumstances when, for example, the settlement agreement formally strips a non-settling party of a legal claim or cause of action, such as a cross-claim for contribution or indemnification, invalidates a non-settling party’s contract rights, or the right to present relevant evidence at a trial. See Denney, 443 F.3d at 273 (reviewing challenge where settlement included a bar order prohibiting claims against settling defendants); Gerber v. MTC Elec. Techs. Co., Ltd., 329 F.3d 297, 305 (2d Cir.2003); see also Alumax Mill Prods., Inc. v. Congress Fin. Corp., 912 F.2d 996, 1002 (8th Cir.1990) (finding standing where settlement dismissed cross-claims with prejudice); Dunn v. Sears, Roebuck & Co., 639 F.2d 1171, 1173-74 (5th Cir.1981) (reviewing challenge where settlement made potential witnesses unavailable to remaining defendants).
Nothing in the Final Order precludes the Non-Settling Defendants from asserting in the district court or in other litigation any claims or defenses that may be available to them. Similarly, nothing in that order requires that they forbear from asserting in the Dutch proceedings, or in any future proceedings in other courts, that participation in the settlement approved by the district court bars subsequent or parallel proceedings. See Zup-nick, 989 F.2d at 98-99 (expressing skepticism that non-settling defendants claims were foreclosed where the stipulations of *219settlement purported to extinguish “any and all claims ... that have been, could have been, or in the future might be asserted” by non-settling defendants, because the agreements were not binding on them). The NonSettling Defendants implicitly concede as much stating: “Paragraph undercuts that argument, as well as appellants’ ability to invoke preclusion defenses in the Dutch actions (or any other actions) based on the outcome of this case.” App. Br. at 13 (emphasis added). It is not, however, sufficient for the Non-Settling Defendants to show that they were somehow “undercut” through the loss of some practical or' strategic advantage. As we have stated, to succeed they must show formal legal prejudice. They have not done so.
Finally, we note that the Non-Settling Defendants have already invoked the “preclusion defenses” in the Dutch proceedings. To us, that is a significant demonstration that nothing in the Final Order prevents or limits them from continuing to assert that Settlement Class members’ participation in the settlement bars, limits, or otherwise impacts claims against them in other jurisdictions. Moreover, in any proceedings to which they are proper parties, the Non-Settling Defendants are free to argue that paragraph 28 of the Final Order is invalid and lacks preclusive effect against them.
In reaching this result, we join our sister courts in holding that a settlement which does not prevent the later assertion of a non-settling party’s claims (although it may spawn additional litigation to vindicate such claims), does not cause the non-settling party “formal” legal prejudice. See, e.g., Agretti 982 F.2d at 247-48 (concluding that a party did not have standing to challenge a settlement agreement in which a co-defendant agreed to declare the contract void because the non-settling party retained the right to assert that the contract was valid and enforceable, despite the obvious practical burden of having its contractual partner disavow the contract); New Mexico ex rel. Energy & Minerals Dep’t v. U.S. Dep’t of Interior, 820 F.2d 441, 444-45 (D.C.Cir.1987) (holding that the Navajo Tribe’s challenge to a provision of a settlement which purported to clarify the Secretary’s position on whether allotments to individual Indians of lands which lie outside the undisputed boundaries of the Navajo Reservation were “Indian lands” was properly dismissed because the Tribe was not bound by the settlement and the Tribe could raise their legal objections in subsequent litigation).
For these reasons, we conclude that the Non-Settling Defendants do not have standing to object to the settlement. In view of this conclusion, we decline to address the remaining issues argued on appeal.

. In February 2013, the district court granted in part and denied in part Plaintiffs’ motion for class certification, excluding from the class investors in 25 countries, which it found had not been shown likely to give preclusive effect to an opt-out class judgment.
