OPINION

This interlocutory appeal deals with a unique statute concerning the claims of California residents against the owners and operators of California-based enterprises. Brought originally in state court, it has been removed to federal court on the theory that the individual claims, when aggregated, meet the minimum requirements of diversity jurisdiction. We have jurisdiction to review the district court’s refusal to remand the dispute back to state court. Because we determine that the recoveries at issue cannot be aggregated to meet the amount in controversy requirement, we vacate the district court order and remand with instructions to return the dispute to the California courts for resolution. 1

*1121 I.BACKGROUND

With passage of the Private Attorneys General Act of 2004 (“PAGA”), the California Legislature fundamentally altered the state’s approach to collecting civil penalties for labor code violations. Though the Labor and Workforce Development Agency (“LWDA”) retained primacy over private enforcement efforts, under PAGA, if the LWDA declines to investigate or issue a citation for an alleged labor code violation, an aggrieved employee may commence a civil action “on behalf of himself or herself and other current or former employees” against his or her employer. Cal. Lab. Code § 2699 (a); Arias v. Super. Ct., 46 Cal.4th 969 , 95 Cal.Rptr.3d 588 , 209 P.3d 923, 930 (2009). If the representative plaintiff prevails, the aggrieved employees are statutorily entitled to 25% of the civil penalties recovered while the LWDA is entitled to 75%. Cal. Lab.Code § 2699(i).

From 2005 to 2010, Plaintiff John Urbino, a California citizen, worked in a nonexempt, hourly paid position for Defendants, each of whom is a corporate citizen of another state, in California. Alleging that Defendants illegally deprived him and other nonexempt employees of meal periods, overtime and vacation wages, and accurate itemized wage statements, Urbino filed a representative PAGA action.

Defendants removed the matter to federal court on the basis of diversity, presenting evidence that the labor code violations identified by Urbino would give rise to claims involving 811 other employees who were issued at least 17,182 paychecks and that the claims could result in liability in excess of the minimum jurisdictional requirements under 28 U.S.C. § 1332 (a)(1). 2 Plaintiff responded by moving the district court to remand the case to state court.

The district court thus had to decide whether the potential penalties could be combined or aggregated to satisfy the amount in controversy requirement. If they could, federal diversity jurisdiction would lie because statutory penalties for initial violations of California’s Labor Code would total $405,500 and penalties for subsequent violations would aggregate to $9,004,050. If not, the $75,000 threshold would not be met because penalties arising from Urbino’s claims would be limited to $11,602.40. Acknowledging a divergence of opinion among the district courts on the issue and noting that this court has yet to address it, the district court found PAGA claims to be common and undivided and therefore capable of aggregation.

II.JURISDICTION AND STANDARD OF REVIEW

We have interlocutory appellate jurisdiction pursuant to 28 U.S.C. § 1292 (b) to review the district court’s denial of Urbino’s motion to remand. 3 “We review de novo a district court’s denial of a motion to remand to state court for lack of federal subject matter jurisdiction.” Chapman v. Deutsche Bank Nat’l Trust Co., 651 F.3d 1039, 1043 (9th Cir.2011).

III.DISCUSSION

To invoke federal diversity jurisdiction under 28 U.S.C. § 1332 (a), a matter must “exceed[ ] the sum or value of $75,000.” Where, as here, “it is unclear or ambiguous from the face of a state-court complaint whether the requisite amount in controversy is pled,” Guglielmino v. *1122 McKee Foods Corp., 506 F.3d 696, 699 (9th Cir.2007), the “removing defendant bears the burden of establishing, by a preponderance of the evidence, that the amount in controversy exceeds” the jurisdictional threshold, Sanchez v. Monumental Life Ins. Co., 102 F.3d 398, 404 (9th Cir.1996).

There is no dispute that Urbino’s individual potential recovery would not meet the $75,000 threshold. Rather, the issue is whether the penalties recoverable on behalf of all aggrieved employees may be considered in their totality to clear the jurisdictional hurdle.

The traditional rule is that multiple plaintiffs who assert separate and distinct claims are precluded from aggregating them to satisfy the amount in controversy requirement. Troy Bank v. G.A. Whitehead & Co., 222 U.S. 39, 40 , 32 S.Ct. 9 , 56 L.Ed. 81 (1911). In Snyder v. Harris, the Supreme Court applied that rule to representative actions, holding that the claims of class members can be aggregated to meet the jurisdictional amount requirement only when they “unite to enforce a single title or right in which they have a common and undivided interest.” 394 U.S. 332, 335 , 89 S.Ct. 1053 , 22 L.Ed.2d 319 (1969). To determine the character of that interest, courts look to “the source of plaintiffs’ claims. If the claims are derived from rights that they hold in group status, then the claims are common and undivided. If not, the claims are separate and distinct.” Eagle v. Am. Tel. & Tel. Co., 769 F.2d 541, 546 (9th Cir.1985).

? simply because claims may have “questions of fact and law common to the group” does not mean they have a common and undivided interest. Potrero Hill Cmty. Action Comm. v. Hous. Auth., 410 F.2d 974, 977 (9th Cir.1969). Only where the claims can strictly “be asserted by pluralistic entities as such,” id., or, stated differently, the defendant “owes an obligation to the group of plaintiffs as a group and not to the individuals severally,” will a common and undivided interest exist, Gibson v. Chrysler Corp., 261 F.3d 927, 944 (9th Cir.2001) (quoting Morrison v. Allstate Indem. Co., 228 F.3d 1255 , 1262 (11th Cir.2000)).

Aggrieved employees have a host of claims available to them—e.g., wage and hour, discrimination, interference with pension and health coverage—to vindicate their employers’ breaches of California’s Labor Code. But all of these rights are held individually. Each employee suffers a unique injury—an injury that can be redressed without the involvement of other employees. Troy Bank, 222 U.S. at 41 , 32 S.Ct. 9 (explaining that an interest is common and undivided when “neither [party] can enforce [the claim] in the absence of the other”). Defendants’ obligation to them is not “as a group,” but as “individuals severally.” Gibson, 261 F.3d at 944 (quotation omitted). Thus, diversity jurisdiction does not lie because their claims cannot be aggregated.

[7] Defendants contend however that the interest Urbino asserts is not his individual interest but rather the state’s collective interest in enforcing its labor laws through PAGA. See, e.g., Arias, 95 Cal. Rptr.3d 588 , 209 P.3d at 934 ; Amalgamated Transit Union, Local 1756, AFL-CIO v. Super. Ct., 46 Cal.4th 993 , 95 Cal. Rptr.3d 605 , 209 P.3d 937, 943 (2009). Accordingly, they argue this is effectively a “case[ ] in which a single plaintiff seeks to aggregate two or more of his own claims against a single defendant,” Snyder, 394 U.S. at 335 , 89 S.Ct. 1053 , and that those claims can be combined to satisfy the minimum amount in controversy requirement of the diversity statute, id. To the extent Plaintiff can—and does—assert anything but his individual interest, however, we are unpersuaded that such a suit, the primary *1123 benefit of which will inure to the state, satisfies the requirements of federal diversity jurisdiction. The state, as the real party in interest, is not a “citizen” for diversity purposes. See Navarro Sav. Ass’n v. Lee, 446 U.S. 458, 461 , 100 S.Ct. 1779 , 64 L.Ed.2d 425 (1980) (courts “must disregard nominal or formal parties and rest jurisdiction only upon the citizenship of real parties to the controversy.”); Mo., Kan. & Tex. Ry. Co. v. Hickman, 183 U.S. 53, 59 , 22 S.Ct. 18 , 46 L.Ed. 78 (1901); see also Moor v. Cnty. of Alameda, 411 U.S. 693, 717 , 93 S.Ct. 1785 , 36 L.Ed.2d 596 (1973) (explaining that “a State is not a ‘citizen’ for purposes of the diversity jurisdiction”).

Accordingly, the federal courts lack subject matter jurisdiction over this quintessential California dispute. We therefore vacate the district court order denying the Plaintiffs motion to remand and direct the district court to return the matter to state court for resolution. 4

VACATED AND REMANDED. Costs on appeal to Urbino.

. The parties do not suggest any alternative basis for federal jurisdiction apart from diversity jurisdiction.

. At the time Defendants removed the case to federal court, they also moved to compel arbitration in accordance with the parties' arbitration agreement.

. Because this court has jurisdiction pursuant to § 1292(b), it need not address Urbino’s alternative contention that the court should exercise pendent appellate jurisdiction.

. Because we find that the district court lacked jurisdiction, we need not address Defendants’ contention that the lower court erred in denying their motion to compel arbitration.
