SUMMARY ORDER

UPON DUE CONSIDERATION, IT IS HEREBY ORDERED, ADJUDGED AND DECREED that the judgment of the district court be AFFIRMED. The mandate shall issue immediately. Nova Group shall bear the costs of appeal.

Nova Group, Inc. (“Nova Group”) appeals from the judgment of the United States District Court for the Southern District of New York (Swain, confirming an arbitration award in favor of Universi-tas Education, LLC (“Universitas”) in the amount of $26,525,535.88, plus prejudgment interest and attorneys’ fees. We assume the parties’ familiarity with the underlying facts, the procedural history, and the issues presented for review.

The sole issued raised on appeal is whether the district court had subject matter jurisdiction over this action. We review this question de novo. See Oscar Gruss & Son, Inc. v. Hollander, 337 F.3d 186, 193 (2d Cir. 2003).

The underlying dispute involves a trustee’s refusal to pay approximately $30 million in life insurance proceeds to the trust beneficiary following the insured’s death in June 2008. When Nova Group (the trustee) rejected a claim by Universitas (the beneficiary) to the death benefit, Universi-tas filed a demand for arbitration, pursuant to a contract-based arbitration clause. On January 24, 2011, the arbitrator held Nova liable to Universitas for $26,525,535.88. Nova then filed a Petition to Vacate in Connecticut Superior Court pursuant to the Federal Arbitration Act (“FAA”), 9 U.S.C. § 10, and Universitas filed an action in New York Supreme Court seeking confirmation of the award pursuant to 9 U.S.C. § 9. Both parties removed the respective actions to federal court, asserting the existence of diversity of citizenship and a federal question.

After losing on the merits, Nova Group then challenged the district court’s subject matter jurisdiction over the case. The court court summarily dismissed this argument as “wholly without merit” and entered judgment for Universitas. A 249. We agree with this decision.

“[Sjubject matter jurisdiction is an un-waivable sine qua non for the exercise of federal judicial power.” Curley v. Brignoli, Curley & Roberts Assocs., 915 F.2d 81, 83 (2d Cir. 1990). So Nova Group’s motion is late in the day, but not untimely.

Subject matter jurisdiction clearly exists here. Federal courts have diversity jurisdiction over controversies between “citizens of different States.” 28 U.S.C. § 1332(a)(1); U.S. Const, art. Ill, § 2. “Diversity jurisdiction exists over ‘civil actions where the matter in controversy exceeds the sum or value of $75,000, exclusive of interest and costs, and is between ... citizens of different States.’ ” Hallingby v. Hallingby, 574 F.3d 51, 56 (2d Cir. 2009) (quoting 28 U.S.C. § 1332(a)(1)).

Universitas is a citizen of New York because it is a limited liability company whose members are domiciled in New York. Nova Group is a Delaware corporation with its principal place of business and headquarters in Simsbury, Connecticut, making it a citizen of both Delaware and Connecticut. The amount in controversy indisputably exceeds $75,000. Nova Group argues that a court must also consider the *64 citizenship of trust beneficiaries for purposes of subject matter jurisdiction if suit is brought by a trustee (which, in this case, would undermine the parties’ diversity of citizenship). This argument was rejected in Navarro Savings Association v. Lee, 446 U.S. 458, 100 S.Ct. 1779, 64 L.Ed.2d 425 (1980). See id. 446 U.S. at 465-66 (affirming the rule, “more than 150 years” old, that permits trustees “to sue in their own right, without regard to the citizenship of the trust beneficiaries”). Contrary to Nova Group’s contentions, Carden v. Arkoma Associates, 494 U.S. 185, 110 S.Ct. 1015, 108 L.Ed.2d 157 (1990), which concerned the citizenship of a limited partnership, did not overrule Navarro. Rather, the Supreme Court explicitly held that the two opinions did not conflict. See id. 494 U.S. at 191-94, 110 S.Ct. 1015. Navarro therefore remains good law, and the district court properly held that it had jurisdiction pursuant to 28 U.S.C. § 1332(a)(1). 1

For the foregoing reasons, and finding no merit in Nova Group’s other arguments, we hereby AFFIRM the judgment of the district court. The mandate shall issue immediately. Nova Group shall bear the costs of appeal.
