    Before KING, CLEMENT, and OWEN, Circuit Judges.
   PER CURIAM:

Certain Underwriters at Lloyd’s, London (Lloyd’s) appeals the district court’s remand of this case to state court. Arguing that complete diversity existed at the time of remand between the plaintiffs and Lloyd’s, the only remaining defendant, Lloyd’s contends that the court was without discretion to remand the case. Due to the absence of allegations or evidence that would allow us to conclusively address this claim, we vacate the district court’s remand order and remand the case to district court for further proceedings.

I

Because we are concerned not with the merits of this case but with the district court’s jurisdiction to decide it, an abbreviated rendition of the facts will suffice. Joannie Jefferson and other plaintiffs sued various defendants in Louisiana state court for various state-law claims related to asbestos exposure. The plaintiffs eventually amended their complaint to name Certain Underwriters at Lloyd’s, London (Lloyd’s) as an additional defendant on the theory that it was liable as an excess insurer. Subsequently, one of the original defendants named the Industrial Development Corporation of South Africa, Ltd. (IDC) and another entity as third-party defendants. IDC removed the case to federal district court under the Foreign Sovereign Immunities Act, asserting that it was a “political subdivision, agency or instrumentality” of the South African government. The propriety of that removal is not in question.

Once in federal court, the case was transferred to the court overseeing the multidistrict litigation on asbestos. That court granted summary judgment in favor of the South African entities and, exercising supplemental jurisdiction over the remaining claims, transferred the case back to the Eastern District of Louisiana. After more defendants were dismissed pursuant to a settlement, Lloyd’s was the sole remaining defendant in the case. The district court then, sua sponte, remanded the matter back to Louisiana state court in accordance with 28 TJ.S.C. § 1367(c) after asserting that “the remaining parties in the matter are not diverse.” Lloyd’s timely appealed, arguing that the remaining parties were in fact diverse and the district court thus had no discretion to remand the case.

II

Before addressing the merits of this appeal, “we must first assure ourselves of our jurisdiction.” The plaintiffs claim that 28 U.S.C. § 1447(d), which provides that “[a]n order remanding a case to the State court from which it was removed is not reviewable on appeal,” prohibits appellate review of the remand order in question here. But as they candidly acknowledge, their jurisdictional challenge to this appeal is foreclosed by the Supreme Court’s decisions in Thermtron Products, Inc. v. Hermansdorfer and Carlsbad Technology v. HIF Bio, Inc. In accordance with these decisions, we have consistently exercised appellate jurisdiction to review remand orders in which “the district court declined to exercise supplemental jurisdiction after first concluding it lacked original subject matter jurisdiction.” Our obligation is to “determine whether the district court had original subject-matter jurisdiction over the remanded claims,” and we turn to that task.

III

“Whether a district court has the discretion to remand a case to state court is a legal question this court reviews de novo.” When a district court has original subject-matter jurisdiction over a claim, it has no authority to remand the case to state court.

Lloyd’s asserts that the district court lacked authority to remand the suit to state court because there was diversity of citizenship between Lloyd’s, the only remaining defendant in the case at the time the case was remanded, and the plaintiffs. Although the suit was originally removed to federal court on another basis, Lloyd’s continues, diversity of citizenship is now an appropriate basis for subject-matter jurisdiction because the claims against the non-diverse defendants have been dismissed. Jefferson responds that the presence of non-diverse defendants at the time of filing. is dispositive, and the district court therefore only had supplemental jurisdiction, which it properly declined to exercise.

Two basic principles guide our decision. First, as a general proposition, the dismissal of non-diverse parties may result in diversity jurisdiction, at least in some circumstances. In Newman-Green, Inc. v. Alfonzo-Larrain, the Supreme Court approved the practice of dismissing 'non-diverse defendants under Federal Rule of Civil Procedure 21 and exercising diversity jurisdiction over the controversy that remains. The Court, in Caterpillar Inc. v. Lewis, declined to disturb a judgment in a case that was improperly removed to federal court on diversity grounds despite the presence of non-diverse defendants. As the Court later explained in Grupo Dataflux v. Atlas Global Group, L.P., “[t]he postsettlement dismissal of the diversity-destroying defendant” in Caterpillar “cured the jurisdictional defect” created by the presence of the non-diverse party. In neither Newman-Green nor Caterpillar did the absence of complete diversity at the time of filing or the time of removal preclude the later exercise of diversity jurisdiction. Put differently, the absence of complete diversity at the time of commencement of an action can generally be cured—and diversity jurisdiction established—by the dismissal of non-diverse parties.

The plaintiffs argue otherwise, relying on the venerable rule that “the jurisdiction of the court depends upon the state of things at the time of the action brought.” This rule clearly applies, for example, to a party’s attempts to create diversity with a post-filing change of citizenship, to the addition of certain non-diverse parties after a suit is brought in federal court, and to post-removal diminutions of the amount in controversy. But the time-of-filing rule cannot be applied indiscriminately to cases involving the dismissal of parties, as Newman-Green and Caterpillar indicate. Here, to be sure, the non-diverse parties were not—as in Newman-Green—dismissed pursuant to Rule 21, and we are not—as in Caterpillar—addressing whether to disturb a final judgment. Those cases establish, however, the broader proposition—followed by courts in a number of different contexts—that the complete diversity of remaining parties to an action generally suffices to secure subject-matter jurisdiction. In the present case, the district court had an alternate basis of subject-matter jurisdiction at each preceding stage of the litigation: the case was properly removed under the Foreign Sovereign Immunities Act once the South African entities were added as parties, and the district court properly exercised supplemental jurisdiction once those entities were dismissed. The dismissal of the claims against the non-diverse defendants “converted” the “less-than-complete diversity which had subsisted throughout the action ,.. to complete diversity.”

The second principle is that “the propriety of the district court’s remand order is judged at the time of that order, not the time of the original removal.” At least twice, we have applied this rule to support the exercise of subject-matter jurisdiction on grounds other than those upon which removal was based.

We have recently applied this maxim to vacate a remand order based on a ground for subject-matter jurisdiction that only arose after the case was removed to federal court. In Firefighters’ Retirement System v. Citco Group Ltd., a case properly removed to federal court based on a related Chapter 11 bankruptcy filing, the district court permissively abstained from exercising jurisdiction and equitably remanded the case to state court. On appeal, we addressed whether the district court had the discretion to remand in light of the post-removal filing of a Chapter 15 bankruptcy. After interpreting the relevant statute to preclude equitable remand of cases related to Chapter 15 bankruptcies, we applied the rule that “[ojnce the district court has assumed jurisdiction over a properly removed case ... [tjhe district court’s authority to remand the case to state court depends on the nature of the district court’s jurisdiction over the claims that comprise the case at the time of the remand.” We therefore vacated the remand order, concluding that although the Chapter 15 filing occurred after removal to federal court, the propriety of the district court’s remand order is judged in this context at the time of remand, not the time of removal. Similarly, in Sigmon v. Southwest Airlines Co., we concluded that even if a case had been improvidently removed to federal court, the district court “acquired jurisdiction, if it did not already exist, when the plaintiffs amended their federal complaint to include an implied cause of action under federal law.”

These principles, taken together, resolve the legal question at the center of this case. Dismissals of non-diverse parties allow for the exercise of diversity jurisdiction, and the propriety of remand in a properly removed case is judged on the basis of the district court’s jurisdiction over the claims remaining at the time of remand, not the time of removal. We thus conclude that the district court had no discretion to remand this case if the remaining parties were diverse at the time of removal.

IV

We turn to the question of whether the remaining parties are in fact diverse. Due to the posture of this case, that is no simple matter: the case was removed by one of the South African entities under the Foreign Sovereign Immunities Act (which does not depend, of course, on the parties’ citizenship), and the district court remanded the plaintiffs’ claims against Lloyd’s without ordering briefing on the matter. The record is thus incomplete in material respects. In particular, while the record suggests that the plaintiffs may be citizens of Louisiana, Texas, or Wisconsin, the citizenship of Lloyd’s remains unclear. Lloyd’s is a citizen of every state in which it has been incorporated or has its principal place of business. It is also, by virtue of 28 U.S.C. § 1332, a citizen of every state in which its alleged insured, Lykes Bros. Steamship Co. (Lykes), is a citizen. Although the district court’s remand order stated that “the remaining parties in the matter are not diverse,” we are unable to ascertain the basis for the court’s conclusion in that regard.

On appeal, Lloyd’s avers that Lykes “was not a citizen of Louisiana, Texas, or Wisconsin” at the relevant time. In support of this conclusion, it states Lykes moved its headquarters from Louisiana to Florida sometime prior to 1995 and that a bankruptcy court confirmed the sale of Lykes to a limited liability company in 1997. That limited liability company, it says, was an indirect subsidiary of a conglomerate that included another company that was in turn bought by a company “headquartered in Germany” that was merged with a different German company in 2005.

The factual material offered by Lloyd’s does not suffice to establish whether Lloyd’s and the plaintiffs were diverse at the time of removal. First, the series of events described by Lloyd’s ends in 2005, some five years before the case was removed, and is not accompanied by any argumentation connecting those events to Lloyd’s state(s) of citizenship. Second, we must decline to take judicial notice of the post-bankruptcy history of Lykes recounted by Lloyd’s in its brief. Mostly drawn from a 2005 press release, these facts are not “generally known within the trial court’s territorial jurisdiction” and cannot be “accurately and readily determined from sources whose accuracy cannot reasonably be questioned.” The request that we take judicial notice of 1997 bankruptcy proceedings confirming the sale of Lykes to a limited liability company is less problematic, but those proceedings do little to establish Lykes’s citizenship at the time the action was removed.

It is, of course, the obligation of the party seeking the federal forum to establish subject-matter jurisdiction. Here, however, Lloyd’s—the party opposing remand—did not have an opportunity to be heard on the matter before the district court concluded that the remaining parties are not diverse. Because the citizenship of Lloyd’s is not clearly established by the record, we vacate the district court’s remand order and remand to the district court for further proceedings to determine whether it has diversity jurisdiction over the remaining claims.

For the foregoing reasons, we VACATE the order of the district court and REMAND this case to the district court for further proceedings consistent with this opinion.
