   SUMMARY ORDER

Defendant-appellant Crane Co. (“Crane”) appeals the decision and order of the United States District Court for the Southern District of New York remanding the action to New York state court following removal pursuant to the “federal officer removal statute,” 28 U.S.C. § 1442(a)(1). We assume the parties’ familiarity with the underlying facts, procedural history, and issues on appeal.

We review a district court’s legal ruling on a motion to remand de novo. Yakin v. Tyler Hill Corp., 566 F.3d 72, 75 (2d Cir. 2009). We review a district court’s decision declining to exercise supplemental jurisdiction for abuse of discretion. Spiegel v. Schulmann, 604 F.3d 72, 78 (2d Cir. 2010) (per curiam).

Crane makes two principal arguments. First, Crane argues that the district court erred in remanding the case because there was original subject matter jurisdiction at the time. Second, Crane argues that, even - assuming the court lacked original jurisdiction, the district court abused its discretion in declining to exercise supplemental jurisdiction. We discuss each argument in turn.

A. Original Jurisdiction

The district court concluded that plaintiffs-appellees Alton and Francis Chapman (the “Chapmans”) had abandoned “any and all claims arising from asbestos exposure which are alleged to have occurred at any government facility, effectively excising] any claim on which a government-contractor defense could be premised and thereby extinguish[ing] the basis on which this action was originally removed.” Special App. at 26. Crane argues that an abandonment or disclaimer of claims does not constitute a “dismissal” of claims over which the district court has original jurisdiction. See 28 U.S.C. § 1367(c)(3) (providing that district courts may decline to exercise supplemental jurisdiction where it has dismissed all claims over which it has original jurisdiction). In other words, Crane argues that the claims giving rise to original jurisdiction must be formally dismissed for a properly removed case to be remanded to state court. The case law is to the contrary. See Valencia v. Lee, 316 F.3d 299, 306 (2d Cir. 2003) (concluding district court abused discretion in retaining supplemental jurisdiction where plaintiffs had abandoned all federal claims; it was a relatively early stage of the case; “[n]o substantive motions had been filed; no judicial opinions had been issued; and the case was not yet ready for trial”); see also Carnegie-Mellon Univ. v. Cohill, 484 U.S. 343, 345, 108 S.Ct. 614, 98 L.Ed.2d 720 (1988) (“A federal district court has discretion under the doctrine of pendent jurisdiction to remand a properly removed case to state court when all federal-law claims in the action have been eliminated and only pendent state-law claims remain.”). It was clear here that the federal claims had been abandoned, and the district court explicitly recognized the claims were no longer in the case. Hence, federal question jurisdiction no longer existed.

Alternatively, Crane asserts that the district court should have retained jurisdiction based on diversity of citizenship. See 28 U.S.C. § 1332. This avenue is also unavailing. “[Wjhen diversity of citizenship is the basis of removal, diversity must exist not only at the time the action was filed in the state court, but also at the time the case is removed to federal court.” 14B Charles Alan Wright & Arthur R. Miller, Federal Practice & Procedure § 3723 (4th ed. 2013); see also United Food & Commercial Workers Union, Local 919, AFL-CIO v. CenterMark Props. Meriden Square, Inc., 30 F.3d 298, 301 (2d Cir. 1994) (noting that the “usual rule is that removability is determined from the record as of the time the petition for removal is filed but where [the] basis of removal is diversity!!,] then diversity of citizenship must exist at [the] time [the] action was filed in state court as well as at [the] time of removal” (citing 14B Wright & Miller § 3723 at 311-12)). Hence, to sustain removal based on diversity, Crane had to demonstrate that diversity of citizenship existed both at the time of the filing of the Chapmans’ original complaint and at the time of removal.

Crane failed to meet its burden here. At the hearing on the Chapmans’ motion for remand, the district court asked the Chap-mans’ counsel whether there was complete diversity at the time the complaint was filed. Counsel responded that he “be-lievfed] that Foster Wheeler was a New York defendant and defeated complete diversity.” Special App. at 18. Later on, the court inquired of Crane’s counsel whether there was any dispute “that at the time the complaint was filed that there was not complete diversity.” Id. at 21. Counsel responded, “No dispute.” Id.

Crane contends on appeal that because it is now the sole remaining defendant in this action, complete diversity exists. Whether non-diverse parties were subsequently dismissed is of no moment, however, when diversity did not exist at the time of the original complaint. See CenterMark, 30 F.3d at 301. Because Crane failed to demonstrate that the parties were diverse when the original complaint was filed, diversity of citizenship cannot serve as a basis for jurisdiction. To the extent that Crane contends that the parties were in fact diverse as of the filing of the original complaint, ’ it has failed to establish as much by competent proof.

B. Supplemental Jurisdiction

Under 28 U.S.C. § 1367(a), “district courts shall have supplemental jurisdiction” over state-law claims “that are so related to claims in the action within [the court’s] original jurisdiction that they form part of the same case or controversy under Article III of the United States Constitution.” Section 1367(c) further provides that a district court may decline to exercise supplemental jurisdiction if “(1) the claim raises a novel or complex issue of State law, (2) the claim substantially predominates over the claim or claims over which the district court has original jurisdiction, (3) the district court has dismissed all claims over which it has original jurisdiction, or (4) in exceptional circumstances, there are other compelling reasons for declining jurisdiction.” Accordingly, a district court may refuse to exercise supplemental jurisdiction on any one of these four grounds. Cf. Itar-Tass Russian News Agency v. Russian Kurier, Inc., 140 F.3d 442, 448 (2d Cir. 1998) (“[T]he discretion to decline supplemental jurisdiction is available only if founded upon an enumerated category of subsection 1367(c),”).

The district court declined to exercise supplemental jurisdiction because the Chapmans had abandoned their claims giving rise to original jurisdiction; it was still an early stage of the proceedings and discovery was not complete; no dispositive motions had been decided; and interests of comity militated in favor of remand because the case was predominately a matter of state law, potentially implicating unsettled questions of state law. See Kolari v. N.Y.-Presbyterian Hosp., 455 F.3d 118, 124 (2d Cir. 2006) (“We have repeatedly held that a district court particularly abuses its discretion when it retains jurisdiction over state-law claims raising unsettled questions of law following dismissal of all original-jurisdiction claims.”). The district court did not abuse its discretion in refusing to exercise supplemental jurisdiction. See 28 U.S.C. § 1447(c) (“If at any time before final judgment it appears that the district court lacks subject matter jurisdiction, the case shall be remanded.”).

We have considered Crane’s remaining arguments and conclude they are without merit. Accordingly, we AFFIRM the judgment of the district court.
