    Before: LYNCH, LOHIER, AND CARNEY, Circuit Judges.
   SUSAN L. CARNEY, Circuit Judge:

This case involves the protracted efforts of Export-Import Bank of the Republic of China (“Ex-Im Bank”) to execute on a $21 million judgment in its favor against the country of Grenada. The judgment, entered in 2007 by the United States District Court for the Southern District of New York (Harold Baer, Jr., Judge), arose from four loans made by Ex-Im Bank to Grenada between 1990 and 2000.

In the loan documents, Grenada waived its sovereign immunity from suit in federal court in New York in connection with the transactions, and thus the District Court was able to enter a valid judgment against Grenada for the amounts owed. Nonetheless, Ex-Im Bank has encountered obstacles in Foreign Sovereign Immunities Act of 1976 (“FSIA”), 28 U.S.C. §§ 1602-1611, protects the assets of a sovereign in the United States from attachment or execution in satisfaction of the judgment. Only if one of the narrow exceptions set out by the FSIA in section 1610 of title 28 applies will Ex-Im Bank be able to pursue satisfaction of its judgment on such assets.

On appeal, we are asked to review the District Court’s decision denying attachment of two sets of assets: first, funds Grenada owes to a private law firm doing business in New York for legal services rendered to Grenada in an unrelated arbitration; and, second, funds that commercial third parties (primarily airlines and cruise lines having some United States-based operations) owe to several Grenadian statutory corporations. Export-Import Bank of Republic of China v. Grenada, 876 F.Supp.2d 263 (S.D.N.Y.2012). We are also asked to review the District Court’s denial of certain discovery requested by Ex-Im Bank in relation to its attachment and execution efforts.

As to the first set of funds, we conclude that we lack jurisdiction to consider whether it is subject to attachment, and we therefore DISMISS the appeal in that respect. As to the second set, we decide that, with one possible exception, the funds are not subject to attachment because they are not “used for commercial activity in the United States” within the meaning of the FSIA. We therefore AFFIRM that aspect of the District Court’s ruling. Certain funds remitted by various airlines through an international air transport industry organization with U.S. operations, however, are allegedly used to service bonds issued to finance Grenada’s main airport. As to that subset, we conclude that the record before us provides an inadequate basis for determining whether the funds either belong to Grenada or are used for commercial activity in the United States. For this reason, and in light of the Supreme Court’s recent decision in Republic of Argentina v. NML Capital, Ltd., — U.S. —, 134 S.Ct. 2250, 189 L.Ed.2d 234 (2014), which rejected any perceived FSIA-based restrictions on discovery related to a foreign sovereign’s assets in the United States, we VACATE the District Court’s order insofar as it denied Ex-Im Bank’s request for post-judgment discovery as to the bond-related funds. We therefore REMAND the cause to enable the District Court to address that request anew.

BACKGROUND

Between 1990 and 2000, Ex-Im Bank extended four loans, with principal totaling approximately $28 million, to Grenada. In the loan documents, Grenada agreed to repay the loans in United States currency deposited into New York City bank accounts. It also warranted that the loans were “commercial acts,” and waived its sovereign immunity from suits in the United States related to the loans and from attachment of related property.

Grenada defaulted on the loans. In March 2007, the United States District Court for the Southern District of New York (Harold Baer, Jr., Judge) granted summary judgment against Grenada in the amount of the approximately $21 million then owed to Ex-Im Bank in principal, plus pre-judgment interest, attorneys’ fees, and statutory interest. Since 2007, Ex-Im Bank has tried, without success, to recover the judgment.

The FSIA protects foreign sovereigns from suit in United States courts. It protects the property of foreign sovereigns in the United States as well: it directs that, subject only to several narrow exceptions, “the property in the United States of a foreign state shall be immune from attachment,] arrest and execution.” 28 U.S.C. § 1609. Only one such exception is relevant here: under some circumstances, the FSIA permits a creditor to execute a judgment against assets of a foreign sovereign if the assets are in the United States when attached and are “used for a commercial activity in the United States.” Id. § 1610(a). At issue in this case are Ex-Im Bank’s efforts under New York law to attach and execute the judgment against two separate sets of Grenada-related assets located in the United States: the “Grynberg Funds” and the “Restrained Funds.

I. The “Grynberg Funds”

In early 2010, RSM Production Corporation (“RSM”) and its individual shareholders — three members of the Colorado-based Grynberg family — brought claims against the government of Grenada before an international arbitration panel. RSM and the Grynbergs alleged, inter alia, that Grenada breached an agreement between RSM and Grenada when it declined to grant RSM a petroleum exploration license. During the arbitration, the international law firm Freshfields Bruckhaus Deringer LLP (“Freshfields”) represented Grenada. In late 2010, the arbitration panel found for Grenada on the merits, dismissed the claims, and ordered the Grynbergs and RSM to pay Grenada’s fees and costs, plus prejudgment interests, in the amount of approximately $298,000, plus interest (the “Grynberg Arbitration Award”).

In February 2011, Grenada filed suit against RSM and the Grynbergs in the United States District Court for the Southern District of New York, seeking confirmation of the international arbitration award. In April 2011, the District Court (Deborah A. Batts, Judge) entered judgment in Grenada’s favor (the “Grynberg Judgment”). Soon after, Grenada filed a separate action in the United States District Court for the District of Colorado, seeking registration of the Grynberg Judgment and recovery on the Grynberg Arbitration Award. Grenada then moved in Colorado to have writs of garnishment issued against RSM, the Grynbergs, and U.S. Bank and JP Morgan Chase Bank, N.A. (“JP Morgan Chase”), each of which held funds belonging to one of the Grynbergs.

In July 2011, after learning of Grenada’s New York and Colorado lawsuits, Ex-Im Bank served restraining notices issued under New York law on U.S. Bank and JP Morgan Chase. It also served restraining notices on Freshfields and Grenada’s Colorado counsel. The effect of the notices was to restrain these entities from taking any action to disburse the funds owed to Grenada in connection with the Grynberg Judgment.

The following month, Ex-Im Bank and Grenada entered into a stipulation (the “Stipulation”) lifting the restraining notices but requiring Grenada to deposit any funds previously subject to those notices with the United States District Court for the Southern District of New York, pending Judge Baer’s 1E> determination of Ex-Im Bank’s rights to the funds in connection with the judgment entered in 2007 in Ex-Im Bank’s favor. In November, 2011, Grenada — which in the meantime had recovered approximately $300,000 from the Grynbergs and RSM — deposited this sum (the “Grynberg Funds”) with the District Court.

In February 2012, Grenada moved for an order declaring the Grynberg Funds immune from attachment under the FSIA, and Ex-Im Bank moved for turnover of the Grynberg Funds. Grenada argued principally that, under the FSIA, the funds were immune from attachment. Ex-Im Bank argued that the funds fell within the FSIA’s “commercial use” exception to immunity.

II. The “Restrained Funds”

Ex-Im Bank concurrently sought to collect on its judgment against Grenada by restraining several airlines and cruise lines, a shipping company, and the International Air Transport Association (“LATA”) (collectively the “Restrained Entities”) from making certain ongoing payments related to their use of facilities located in Grenada. The payments, comprised primarily of taxes, fees, and other charges, were owed to certain corporate entities (the “Statutory Corporations”), which Grenada created to perform various civic functions, such as managing Grenada’s airports, seaports, and similar facilities. Charges associated with the use of certain air transport facilities in Grenada are payable not to a Grenada statutory corporation, however, but to the IATA, with operations in the United States, as we discuss further below.

In its restraining notices — served in November 2011 pursuant to New York law— Ex-Im Bank asserted that the Restrained Entities “may owe a debt to the judgment debtor, Grenada, or may be in possession or in custody of property in which the judgment debtor has an interest.” See, e.g., Restraining Notice to Virgin Atlantic Airways, Joint Appendix (“J.A.”)472-74 (citing N.Y. C.P.L.R. 5222(b)). By virtue of the notices, Ex-Im Bank laid claim to the stream of funds normally paid by the Restrained Entities to the Statutory Corporations (the “Restrained Funds”).

In response, all but one of the Restrained Entities withheld the payments owed to the Statutory Corporations. Virgin Atlantic Airlines instead chose to deposit with the District Court, pending resolution of Ex-Im Bank’s rights, funds it would ordinarily pay to the Statutory Corporations, directly or through IATA.

In March 2012, Grenada and the Statutory Corporations moved in the District Court to vacate the restraining notices. They asserted that the Restrained Funds are not subject to attachment, arguing that: the Statutory Corporations are juridical entities separate from Grenada that cannot be held responsible for Grenada’s debts; and that, in any event, the FSÍA immunizes the Restrained Funds from attachment. In support of their motions, Grenada and the Statutory Corporations submitted affidavits made by various executives in the Statutory Corporations, describing the structure and purpose of each of those entities, on what basis each charged fees, and how each planned to use the Restrained Funds. Ex-Im Bank opposed the motions and cross-moved for discovery related to the operations of the Statutory Corporations and their planned use of the Restrained Funds.

III. District Court Decision

In an Opinion and Order issued on June 22, 2012, the District Court granted Grenada’s motion for a declaration that the Grynberg Funds are immune from attachment; granted Grenada’s and the Statutory Corporations’ motions to vacate the restraining notices; and denied Ex-Im Bank’s motion for discovery related to the Restrained Funds. Exp.Imp. Bank of Republic of China v. Grenada, 876 F.Supp.2d 268 (S.D.N.Y.2012) (“Grenada”).

The court held that neither set of funds, in the FSIA’s words, was “property in the United States of a foreign state ... used for a commercial activity in the United States,” and that they were therefore immune from attachment, notwithstanding Grenada’s various waivers. See id. at 264-65 (quoting 28 U.S.C. § 1610(a)). With respect to the Grynberg Funds, it reasoned that because Grenada had not yet transferred the Grynberg Funds to Fresh-fields, the funds had yet to be “used” for any commercial activity in the United States. Id. at 265, 105 P. 214. With respect to the Restrained Funds, the District Court declined to address whether the Statutory Corporations are liable for the judgment against Grenada on the theory that they are alter egos of Grenada. Id. at 267, 105 P. 214. Rather, the court determined that, even assuming them to be Grenada’s alter egos, the FSIA bars the notices, because the Restrained Funds were not “used for commercial activity” since “[t]he payments that the Corporations receive from the[ ] Restrained Entities are used as a source of revenue for carrying out public functions in Grenada.” Id. In reaching this conclusion, the court focused both on their source and the use to which the Restrained Funds were put. The court observed, for example, that “the Restrained Funds are not involved in regular commercial transactions, but rather are collected as part of the Corporations[’] regulation of and provision of access to Grenada’s public facilities and services.” Id.

Finally, the District Court denied Ex-Im Bank’s request for further post-judgment discovery. After reviewing the parties’ “supplemental submissions regarding the extent of discovery and what Ex-Im Bank needed to show to obtain discovery,” the court concluded simply that “discovery [wa]s not warranted.” Id. at 267 n. 5, 105 P. 214.

IV. Subsequent Procedural History

After the District Court issued its decision, Ex-Im Bank sought to stay vacatur of the restraining notices and disbursement of the Grynberg Funds pending appeal. On August 17, 2012, the District Court denied the motion, but granted a temporary stay until August 31, 2012. Ex-Im Bank then moved this Court for a stay, and on October 3, 2012, the motion was denied. Shortly thereafter, all restraining notices were lifted, and the Grynberg Funds were disbursed.

DISCUSSION

On appeal, we are asked to consider whether the District Court erred in concluding that the Grynberg Funds and the Restrained Funds are immune from attachment under the FSIA and whether the District Court exceeded its discretion in denying Ex-Im Bank’s request for certain post-judgment discovery.

With regard to the Grynberg Funds, we conclude that Ex-Im Bank’s appeal is moot because the funds have already been released to Grenada. With regard to most of the Restrained Funds, we conclude that the FSIA does not permit Ex-Im Bank to attach them because they are not “used for a commercial activity in the United States.” As to a certain subset of the Restrained Funds, however, the factual record before us provides an inadequate basis to determine whether the funds may be attachable. For this reason, and in light of recent Supreme Court precedent interpreting the FSIA not to bar broad discovery in aid of executing a judgment against a sovereign, we vacate the District Court’s order insofar as it denied Ex-Im Bank post-judgment discovery. We therefore remand for further proceedings with respect to that issue.

I. Legal Framework

As a matter of common law, foreign sovereigns have long been recognized as presumptively immune from suit in United States courts. See Samantar v. Yousuf, 560 U.S. 305, 311-12, 130 S.Ct. 2278, 176 L.Ed.2d 1047 (2010). Implementing this presumption, the practice for many years was for the State Department to file a “suggestion of immunity” in cases regarding particular foreign sovereigns. See id. at 311-13, 130 S.Ct. 2278. Over time, inconsistency and unpredictability came to characterize the government’s practice in applying the immunity doctrine. See Verlinden B.V. v. Cent. Bank of Nigeria, 461 U.S. 480, 487-88, 103 S.Ct. 1962, 76 L.Ed.2d 81 (1983). With a goal of regularizing that practice and establishing the jurisdiction of United States courts in certain circumstances to hear claims against foreign nations, Congress in 1976 enacted the FSIA. Id. at 488, 103 S.Ct. 1962.

1 The FSIA strongly reflects the presumption of immunity: except in few limited circumstances, it provides that “a foreign state shall be immune from the jurisdiction of the courts of the United States and of the States.” 28 U.S.C. § 1604 (emphasis added). As a further element of immunity, it provides that— also subject to certain exceptions — “the property in the United States of a foreign state shall be immune from attachment!,] arrest and execution.” 28 U.S.C. § 1609. Thus, to sue successfully and enforce an award against a foreign state in a United States court, a plaintiff must demonstrate both that the foreign state is not immune from suit and that its assets in the United States are not immune from attachment or execution.

In this case, Grenada waived its immunity from suits arising out of the loans on which it defaulted. It also waived sovereign immunity from attachment and execution. See Loan Agreement § 9.06, Dist. Ct. Dkt. No. 9, Ex. 4; supra note 1. Notwithstanding these waivers, it argues that its assets in the United States are immune from attachment to satisfy the judgment against it. Our task is to determine whether, as Ex-Im Bank contends, any one of the assets at issue falls 17 within one of the exceptions to the FSIA’s grant of immunity.

The relevant exceptions appear in two subsections of the Act: section 1610(a), which deals with property belonging to a foreign state, and section 1610(b), which deals with property belonging to an agency or instrumentality of a foreign state. Under the former provision — which lies at the core of this appeal — a party may execute against “[t]he property in the United States of a foreign state,” even when the state has waived its immunity to attachment or execution, only to the extent that such property is “used for a commercial activity in the United States.” 28 U.S.C. § 1610(a).

In interpreting these provisions, we are mindful of the historical context (referenced above) within which the FSIA was enacted. Common law extended virtually absolute immunity from suit to sovereign nations. See Samantar, 560 U.S. at 311-12, 130 S.Ct. 2278 (citing Schooner Exch. v. McFaddon, 7 Cranch 116, 3 L.Ed. 287 (1812)). This doctrine of “complete” sovereign immunity, adopted and applied by our own courts through the mid-twentieth century, carried a number of unintended consequences, including that it “deprived private citizens [and corporations] conducting business with foreign governments of a legal remedy in court.” M. Mofldi, The Foreign Sovereign Immunities Act and the “Commercial Activity” Exception: The Gulf Between Theory and Practice, 5 J. Int’L Legal Stud. 95, 98 (1999). In 1952, the State Department responded to such concerns by adopting a new rule in a document that later became known as the “Tate Letter,” which proposed limiting the doctrine of complete sovereign immunity. See Connecticut Bank of Commerce v. Republic of Congo, 309 F.3d 240, 251-52 (5th Cir.2002) (“Connecticut Bank”). In the Tate Letter, the State Department announced that it would “recommend denying immunity in suits based on a foreign 15 sovereign’s strictly commercial activities.” Id. at 252. But the Letter also recognized a distinction between immunity from suit and immunity from execution of judgment. Thus, even “[i]f a plaintiff successfully obtained a final judgment against a foreign sovereign, he still had to rely on the foreign state to pay the judgment voluntarily.” Id.

The FSIA shifted the responsibility for making determinations about foreign sovereign immunity from the Executive Branch to the Judiciary. Id. Like the Tate Letter, the Act ended blanket immunity from suit on claims arising from the commercial conduct of foreign sovereigns in the United States. Id. But, unlike the Tate Letter, it also provided private litigants with a mechanism — albeit a circumscribed one — for executing on the property in the United States of a foreign state. Id. The limitations of that mechanism can, in some cases, still render the grant of jurisdiction under the FSIA entirely ineffectual, essentially providing a “right without a remedy” De Letelier v. Republic of Chile, 748 F.2d 790, 798 (2d Cir.1984). The potential for this anomaly was recognized and tolerated by Congress, however, in enacting the FSIA, id. at 798-99, and so cannot bear heavily on our analysis.

In this case, to find that Ex-Im Bank may attach either set of funds, we must conclude that those funds are: (1) “property in the United States”; (2) “of a foreign state,” i.e., that they belong to Grenada; and (3) that they are “used for a commercial activity in the United States” when the writ of attachment or execution issues. Aurelius Capital Partners, LP v. Republic of Argentina, 584 F.3d 120, 130 (2d Cir.2009); see also Conn.Bank, 309 F.3d at 253-54.

We review a district court’s ruling on a request for an order of attachment for abuse of discretion. See NML Capital, Ltd. v. Republic of Argentina, 680 F.3d 254, 257 (2d Cir.2012). We similarly review a district court’s discovery rulings for abuse of discretion. See EM Ltd. v. Republic of Argentina, 695 F.3d 201, 207 (2d Cir.2012) (“EM II”). A district court is said to have abused its discretion if it has 12 based its ruling on an erroneous view of the law, made a clearly erroneous assessment of the evidence, or rendered a decision that cannot be located within the range of permissible decisions. NML Capital, Ltd., 680 F.3d at 257.

II. The Grynberg Funds

We do not have jurisdiction to consider whether the Grynberg Funds are attachable because that question has been mooted by the release of those funds from the District Court. As we have stated in other contexts, to have jurisdiction over a dispute, “at all times, the dispute before the court must be real and live, not feigned, academic, or conjectural. When the issues in dispute between the parties are no longer live, a. case becomes moot.” Lillbask ex rel. Mauclaire v. Conn. Dep’t of Educ., 397 F.3d 77, 84 (2d Cir.2005) (internal citation and quotation marks omitted). In this case, put simply, the Grynberg Funds no longer exist in the United States as potentially attachable property of Grenada. The dispute as to these funds is therefore moot.

Ex-Im Bank presents two arguments to the contrary. First, it asserts that another, similar arbitration brought by RSM against Grenada in 2004 resulted in an award of arbitration fees and costs against RSM, and contends that the amenability to attachment of any recovery on that award depends on our resolution of the Grynberg Funds question. Second, it maintains that, because Ex-Im Bank still might be able to recover the Grynberg funds from Grenada or “their ultimate destination” (presumably, Freshfields), their amenability to attachment presents a live case or controversy. Appellant’s Br. n. 12. Neither of these circumstances, however, suffices to revive the dispute.

A. The RSM Arbitration

In 2004, the Grynbergs’ company— RSM — initiated arbitration with Grenada, alleging claims against the country related to those the family members brought in the Grynberg Arbitration six years later. In March 2009, an arbitration panel found for Grenada after determining that Grenada had not breached any obligation to RSM. The panel also concluded that each party should bear its own arbitration costs.

In June 2009, RSM moved the arbitrators to annul the March arbitration judgment. Pursuant to regulations of the International Centre for Settlement of Investment Disputes (“ICSID”), which governed the arbitration, RSM was responsible for financing the annulment proceeding. In 2010, however, after RSM and the Grynbergs initiated the separate Grynberg Arbitration, RSM (as alleged by Grenada) “stopped complying with its obligation to finance the annulment proceedings.” Application and Mem. of Law for Recognition and Entry of ICSID Award as Judgment at 5, In re Application of Grenada v. RSM Prod. Corp., No. 1:11 Misc. 188 (S.D.N.Y. June 3, 2011), ECF No. 1.

In early 2011, an ad hoc committee of arbitrators for the ICSID issued an order discontinuing the annulment proceedings for lack of payment. In conjunction with that order, the ad hoc committee ordered RSM to pay Grenada’s legal fees and costs of arbitration, amounting to $186,072.81 (the “RSM Arbitration Award”). See id. at 7. Shortly thereafter, Grenada moved in the United States District Court for the Southern District of New York for confirmation of the RSM Award and for judgment against RSM. Id. at 1.

In August 2011, Ex-Im Bank and Grenada entered into the Stipulation that we have described above with respect to the Grynberg Funds (and whose terms apply also to the RSM Award). See J.A. 85-87. In it, Grenada undertook to attempt to collect the RSM Award and agreed that “[a]ny funds collected by Grenada in connection with collection efforts ... shall be deposited with the [District] Court.” Id. at 87.

According to Ex-Im Bank’s brief on appeal, Grenada has yet to collect any funds in satisfaction of the RSM Award, let alone deposit them with the District Court. Nevertheless, Ex-Im Bank argues that our determination of the status of the Grynberg Funds will necessarily resolve the status of the RSM Funds, and that therefore the legal question regarding the Grynberg Funds is not moot, notwithstanding their disbursement to Grenada. We are not persuaded.

As an initial matter, it is simply not apparent that any resolution of the status of the Grynberg Funds will necessarily resolve the status of the RSM Funds. Nothing in the August 2011 Stipulation suggests that the District Court’s determination of Ex-Im Bank’s rights to the Grynberg Funds would govern the Bank’s rights to the RSM Funds, or vice versa. Nor have we been directed to any agreement between the parties that would require release to Ex-Im Bank of the RSM Funds were we to order repayment to Ex-Im Bank of the Grynberg Funds.

Further, even if our decision regarding the Grynberg Funds bore in some direct way on the proper treatment of the RSM Funds, the Grynberg Funds issue would still be moot. Ex-Im Bank has pointed to no evidence that the Grynberg Funds remain in Grenada’s possession in the United States. No matter how helpful a decision on the merits may be in also resolving the Bank’s rights to the RSM Funds, such a decision would be merely advisory. See Cnty. of Suffolk, N.Y. v. Sebelius, 605 F.3d 135, 137-38 (2d Cir.2010) (concluding that plaintiffs claims to recover grant funding from the federal government were moot because the funding had already been disbursed to other grant applicants).

B. Recovery from Grenada or Freshfields

Ex-Im Bank further disputes the mootness of the Grynberg Funds issue on the theory that “an order of this Court to the effect that the Grynberg Funds belong to Ex-Im Bank would then require Grenada to return those funds forthwith to Ex-Im Bank.” Appellant’s Br. 25 n. 12. This contention ignores that, under the FSIA, the Grynberg Funds were arguably subject to attachment only after they were deposited with the District Court and— according to Ex-Im Bank, at least — “designat[ed]” for commercial use in the United States: namely, payment to Fresh-fields. See EM Ltd. v. Republic of Argentina, 473 F.3d 463, 484 (2d Cir.2007) (“EM I”) (holding that funds were unavailable for attachment under section 1610 because they were never used for, or designated for use in, commercial activity). The withdrawal of the funds from deposit with the District Court has fundamentally altered their status. The funds no longer exist as discrete property of Grenada held in the United States and arguably designated for a commercial use in the United States. Once the Grynberg Funds were transferred to Grenada, they became part of the undifferentiated property of the sovereign. In these circumstances, we do not have jurisdiction to consider whether, in retrospect, those funds might have been attachable when they were on deposit in the District Court. Cf. Fidelity Partners, Inc. v. First Trust Co. of N.Y., 142 F.3d 560, 564-66 (2d Cir.1998) (stating that an “attachment ... proceeding” is moot where the property the judgment creditor seeks to attach “no longer exists”).

Even if Grenada paid the Grynberg Funds directly to Freshfields in the United States, and this payment constituted “commercial activity in the United States,” the Grynberg Funds issue would still be moot. Under Federal Rule of Civil Procedure 69, the “procedure on execution” in federal court upon a money judgment “must accord with the procedure of the state where the court is located.” Fed.R.Civ.P. 69(a)(1). We thus look to New York law to determine what property might be attachable in execution of Ex-Im Bank’s judgment against Grenada. Pursuant to N.Y. C.P.L.R. 5201(b) — which identifies the “[property against which a money judgment may be enforced” — a judgment creditor may execute against the property of a judgment debtor “whether [that property] consists of a present or future right or interest and whether or not it is vested.” The statute does not, however, contemplate execution against property that once belonged to the judgment creditor but now lawfully belongs to a third party. In other words, even if Grenada actually used the Grynberg Funds for the purpose Ex-Im Bank argued those funds were designated for when they were deposited in the District Court, the payment of the funds to Freshfields would render the question of their attachability moot. We therefore dismiss the appeal with respect to the Grynberg Funds.

III. The Restrained Funds

The District Court dedicated only a brief segment of its opinion to considering whether the streams of payments made by the Restrained Entities to the Grenadian Statutory Corporations are immune from attachment. It concluded that the funds are not used for commercial activity in the United States, but rather are of a fundamentally public character, and thus do not fall within the FSIA’s “commercial activity” exception. See Grenada, 876 F.Supp.2d at 267.

The District Court relied in its analysis on Republic of Argentina v. Weltover, Inc., 504 U.S. 607, 112 S.Ct. 2160, 119 L.Ed.2d 394 (1992), the seminal Supreme Court case interpreting the phrase “commercial activity,” as defined by the FSIA, for purposes of assessing a foreign sovereign’s jurisdictional immunity from suit under section 1605(a)(2). In Weltover, the Supreme Court considered whether Argentina was engaged in a “commercial activity” when, in the 1980s, it issued bonds to raise United States dollars for the purpose of stabilizing Argentina’s currency. Id. at 609-14, 112 S.Ct. 2160. The Court held that, although Argentina’s purpose in issuing the bonds was undoubtedly of a public or governmental character, the proper focus of the “commercial activity” inquiry under the plain language of the FSIA is the “nature,” not the “purpose,” of the sovereign’s conduct. Id. at 614, 112 S.Ct. 2160 (quoting 28 U.S.C. § 1603(d)). Because Argentina acted “not as regulator of a market, but in the manner of a private player within it,” its conduct was “commercial” under the FSIA. Id. at 614, 112 S.Ct. 2160.

Applying the general framework established in Weltover, the District Court concluded that “the Restrained Funds are not involved in regular commercial transactions, but rather are collected as part of the [Statutory Corporations’] regulation of and provision of access to Grenada’s public facilities and services.” Grenada, 876 F.Supp.2d at 267. In support of this conclusion, the court relied primarily on a district court case holding that taxes owed by various airlines to the Republic of Nicaragua were immune from attachment under the FSIA. See id. (citing LNC Invs., Inc. v. Republic of Nicaragua, No. 96 Civ. 6360(JFK), 2000 WL 745550, at *5 (S.D.N.Y. June 8, 2000)). According to the District Court, the Restrained Funds, like taxes, “are used as a source of revenue for carrying out public functions in Grenada.” Id.

On appeal, the parties’ arguments largely respond to the District Court’s focus on the nature of the services provided in Grenada by the Statutory Corporations in exchange for payment by the Restrained Entities. Ex-Im Bank asserts that the affidavits provided by Grenada reflect the private character of the fees and other charges collected by the Statutory Corporations. For example, the Chairman of the Grenada Airports Authority (“GAA”) explained in his affidavit that among the “Usage Fees” the GAA collects from the airlines are a “Parking Fee,” a “Baggage Screening” fee, and “Overtime Charges.” J.A. 526-27. These, according to Ex-Im Bank, are “precisely the kinds of services purchased from private vendors around the world.” Appellant’s Br. at 30. Grenada counters that these payments from the Restrained Entities are of a governmental and “exclusively public” nature: “the payment of the Restrained Funds to the Statutory Corporations is compelled by Grenadian law and mandatory to the users of facilities and services for which there is no privately available alternative.” Appellee’s Br. at 21-22.

In our view, the District Court erred to the limited extent that it focused its analysis (as did the parties) on how Grenada generated, the Restrained Funds rather than on how Grenada uses them. We agree with the District Court’s 17 ultimate conclusion, however, that the Restrained Funds are not attachable because, once generated, they are used to serve public purposes, and that use takes place in Grenada.

A. Funds Paid to Grenadian Statutory Corporations for Use of Seaports and Airports

Our Court does not appear to have addressed whether property held in the United States by third parties and owed to a foreign sovereign may be “used for a commercial activity in the United States” and thus subject to attachment under section 1610(a) of the FSIA. But both the Fifth Circuit and the Ninth Circuit have, and we adopt their shared approach here. See Conn. Bank, 309 F.3d 240; Af-Cap Inc. v. Chevron Overseas (Congo) Ltd., 475 F.3d 1080 (9th Cir.2007).

In Connecticut Bank, the Fifth Circuit considered whether assets held by Texas oil companies and owed to the Republic of Congo as royalties and taxes were attachable to satisfy a judgment against the Congo. See 309 F.3d at 246-247. In determining whether the assets were attachable, the parties and the district court focused on whether the services provided by the Congo in exchange for payment from the oil companies were commercial in nature. According to the Fifth Circuit, this “was the wrong question to consider.” Id. at 251. “What matters under the statute is not how the Congo made its money, but how it spends it. The amenability of these royalties and taxes to garnishment depends on what they are ‘used for,’ not on how they were raised.” Id. The court remanded the case and instructed that, “[i]f it turns out that the royalties and tax obligations are not used for any commercial activity in the United States, the district court should dissolve the writs of garnishment and dismiss the action.” Id. at 260-61.

In Af-Cap, the Ninth Circuit considered a judgment-creditor’s efforts to recover a judgment against the Republic of Congo by attaching assets held by third parties and owed to the Congo pursuant to oil- and-gas drilling agreements. See 475 F.3d at 1084. The Ninth Circuit adopted the Fifth Circuit’s test, agreeing that “the phrase ‘used for’ in § 1610(a) is not a mere syntactical infelicity that permits courts to look beyond the ‘use’ of property, and instead try to find any kind of nexus or connection to a commercial activity in the United States.” Id. at 1087 (quoting Conn. Bank, 309 F.3d at 254). Rather, the court explained, the word “used” should be given its ordinary, conversational meaning, so that property is “used for” commercial activity under section 1610(a) “when the property in question is put into action, put into service, availed or employed for a commercial activity,” and not merely when it is used “in connection with a commercial activity or in relation to a commercial activity.” Id. at 1091 (emphases in original).

Applying this framework, the Af-Cap court determined that the specific assets identified as attachable by the judgment-creditor there — including money owed to the Congo by U.S. oil-and-gas companies as consideration for rights to drill and distribute oil in the Congo — were not “used for a commercial activity in the United States” because, among other things, the relevant ventures occurred abroad and, in any event, even if the funds were generated in connection with that commercial activity, they were not necessarily used commercially in the United States. See id. at 1094. Accordingly, the court concluded that the assets were immune from attachment. Id. at 1096.

We agree with the Fifth and Ninth Circuits’ interpretation. First, we understand the word “used,” read literally, to require not merely that the property at issue relate to commercial activity in the United States, but that the sovereign actively utilize that property in service of that commercial activity. See% Conn. Bank, 309 F.3d at 254; Af-Cap, 475 F.3d at 1087-88. Second, we find this interpretation of the statutory language — one narrower than a general “relation to” requirement — to be more consistent with the structure and purpose of the FSIA. As described above, the statute was intended to reduce the scope of immunity from suit previously extended to foreign sovereigns engaging in commercial activity in the United States. See Conn.Bank, 309 F.3d at 252; Af-Cap, 475 F.3d at 1088-89; see also H.R.Rep. No. 94-1487, at 7 (1976), as reprinted in 1976 U.S.C.C.A.N. 6604, 6605 (noting that the FSIA codifies the “restrictive principle” of sovereign immunity, under which “the immunity of a foreign state is ‘restricted’ to suits involving a foreign state’s public acts (jure imperii) and does not extend to suits based on its commercial or private acts (jure gestionis)”). But it was also designed to maintain broad immunity from attachment of a sovereign’s property in the United States. See H.R.Rep. No. 94-1487, at 27 (noting that the FSIA modified the rule precluding execution against a foreign state’s property by “partially lowering the barrier of immunity from execution” (emphasis added)).

The various exceptions set forth in the FSIA itself make apparent the statute’s dual approach: to foreign sovereign immunity from suit (on the one hand), and to immunity of foreign assets from attachment and execution (on the other). Section 1605(a)(2), for example, eliminates immunity from suit in the United States for a foreign sovereign in any case “in which the action is based upon ... an act performed in the United States in connection with a commercial activity of the foreign state elsewhere; or upon an act outside the territory of the United States in connection with a commercial activity of the foreign state elsewhere” that causes a “direct effect in the United States.” 28 U.S.C. § 1605(a)(2) (emphases added). The “in connection with” language allows for suits against a foreign sovereign that merely relate to commercial activity. The breadth of this provision stands in contrast to the more limited scope of section 1610(a), which, as explained above, allows execution upon the property of a foreign sovereign only to the extent that the property is “used for a commercial activity in the United States.” 28 U.S.C. § 1610(a) (emphasis added); see also Conn. Bank, 309 F.3d at 255 (noting “an obvious difference in the way these two different 12 immunities have been crafted”).

For the most part, the application of this framework to the facts presented here is relatively straightforward. We do not consider the nature of the services provided in Grenada by the Statutory Corporations in exchange for the Restrained Funds, because the source of the property is irrelevant to the section 1610(a) analysis. Instead, we focus on the use to which Grenada puts — or clearly intends to put, by virtue of some formal designation or other specific means — the funds at issue. Even if, as Ex-Im Bank argues, the services provided by the Statutory Corporations are “precisely the kinds of services purchased from private vendors around the world,” Appellant’s Br. at 30, funds that the Restrained Entities pay to the Statutory Corporations for those services in Grenada are immune from attachment because they are not used by the Statutory Corporations for commercial activity that takes place in the United States. As the District Court found and the record supports, the Restrained Funds (with the possible exception of the IATA Funds, as discussed below), are devoted to “carrying out public functions in Grenada,” and “used for the maintenance of facilities and services in Grenada.” Grenada, 876 F.Supp.2d at 267 & n. 6. They fail both the “commercial use” and the “in the United States” prongs. They therefore do not meet the “commercial activity” exception to attachment provided by section 1610(a).

B. The IATA Funds & Post-Judgment Discovery

According to Ex-Im Bank, one subset of the Restrained Funds calls for a different analysis. Ex-Im Bank points to the affidavit of the Chairman of the GAA, Rodney George, in which George states that the GAA is empowered to collect various taxes, fees, and charges from all airlines flying into Grenada. J.A. 526. GAA does not collect these fees from non-Grenadian airlines, however. Rather, it directs those airlines to “remit their Usage Fees through the International Air Transport Association,” an international industry organization that “provides a variety of functions to the international air transport community.” Id. at 527-28. In the past, according to the George Affidavit, IATA disbursed the funds received from non-Grenadian airlines (the “IATA Funds”) directly to the GAA; however, beginning in April 2010 and lasting at least until George signed his affidavit in March 2012, IATA has instead forwarded the funds to an entity called First Citizens Trustee Services Limited (“First Citizens”). See id. at 528. First Citizens acts as a trustee responsible for servicing certain bonds issued by or on behalf of the GAA (the “GAA Bonds”), and the proceeds of the bonds are used to finance the operations of Grenada’s main airport.

Ex-Im Bank argues that, under Welt-over, the IATA Funds may be attachable assets. As described above, the Weltover Court held that Argentina engaged in conduct of a commercial, not governmental, nature when it issued bonds that were “in almost all respects garden-variety debt instruments: They may be held by private parties; they are negotiable and may be traded on the international market ...; and they promise a future stream of cash income.” 504 U.S. at 615, 112 S.Ct. 2160. The Court there explained that participation “in the bond market in the manner of a private actor” constitutes “commercial activity” under the FSIA. Id. at 617, 112 S.Ct. 2160. Ex-Im Bank urges us to hold that (1) transactions relating to the GAA Bonds “fall squarely in the Weltover doctrine,” and (2) any portion of the IATA Funds directed to pay United States-based holders of these bonds is “used for a 18 commercial activity in the United States.” Appellant’s Br. at 33.

In our view, the record before us does not provide a sufficient basis to make such determinations. As Ex-Im Bank observes in its briefing before the Court, the factual record as to the GAA Bonds and the IATA Funds is sparse. The record does not disclose many facts that would bear on a careful determination of immunity from attachment. These include: the manner or location in which the bonds were issued; the location of First Citizens (the Trustee responsible for servicing the bonds); the locations or identities of the bondholders (including whether they are private or public); the manner or location in which the bonds are traded; and the method by which the bondholders receive payments. Without this information, we are unable to adequately evaluate Weltover’s applicability to the present action, or to discern whether the IATA Funds are “used for” commercial activity in the United States.

We note that the record is also unclear as to a separate prong of our attachability inquiry: whether the IATA Funds even belong to Grenada or one of its alleged alter egos. In his affidavit, GAA’s George alludes to an “Airport Enhancement and Financing Service Agreement” to which IATA and the GAA are parties. J.A. 528. According to George, “The Agreement acknowledges that the GAA has ‘definitively and irrevocably transferred, assigned, set-over and otherwise conveyed to the Trustee ... all of its right, title and interest in, to and under ... all [Usage Fees] and all rights to receive any payments relating to the [Usage Fees].” Id. (alterations in the original). The agreement itself, however, is not contained in the record before us and the language quoted is unaccompanied by any citation; we are presented only with the recited sentence itself. In our view, this is too thin a reed upon which to base a definitive legal judgment as to whether the IATA Funds are the property of the GAA or, if so, whether the GAA’s property is also Grenada’s. We therefore decline to rule now on whether Ex-Im Bank may attach the IATA funds. Instead, we remand to the District Court to consider anew the possibility of further discovery as to these issues.

Our conclusion in this regard is reinforced by the disposition and tenor of the Supreme Court’s recent decision in Republic of Argentina v. NML Capital, Ltd., — U.S. —, 134 S.Ct. 2250, 189 L.Ed.2d 234 (2014), which in turn affirmed our decision in EM II, 695 F.3d 201 (2d Cir.2012). In EM II, we upheld the district court’s grant of post-judgment discovery related to assets held at third-party banks in the United States by judgment-debtor Argentina. 695 F.3d at 204-05. In so doing, we concluded that judgment creditors need not satisfy the “stringent requirements for attachment” under the FSIA “to simply receive information about [a sovereign’s] assets.” Id. at 209. We also noted that discovery of information related to assets held by third-party banks did not infringe Argentina’s sovereignty even if those assets ultimately proved immune from attachment: “Once the district court had subject matter and personal jurisdiction over Argentina, it could exercise its judicial power over Argentina as over any other party, including ordering third-party compliance with the disclosure requirements of the Federal Rules.” Id. The Supreme Court later granted certiorari in EM II, and affirmed. See NML Capital, 134 S.Ct. at 2258. The Court emphasized the absence of any FSIA provision “forbidding or limiting discovery in aid of execution of a foreign-sovereign judgment debt- or’s assets,” and endorsed an approach to discovery — once jurisdiction over the foreign sovereign has been established, as it has here — more generally consonant with the Federal Rules of Civil Procedure. Id. at 2256-57.

In light of the Supreme Court’s decision, and given the circumstances before us, we think it prudent to vacate the District Court’s decision denying discovery, and remand for the District Court’s reconsideration in light of the altered legal landscape. As explained above, Ex-Im Bank has had no opportunity to examine the circumstances relevant to the FSIA’s application to the IATA Funds, and in particular, the uses to which those funds may be put in service of the GAA Bonds. The strictures of Fed.R.Civ.P. 69 will still govern the District Court’s assessment of the requested discovery, but any lingering concern that the FSIA alone might presumptively bar further discovery has been eliminated by the Supreme Court in NML Capital.

CONCLUSION

In sum, we conclude that: (1) the question whether the Grynberg Funds may be attached is moot, because those funds have already been disbursed; (2) the District Court properly vacated the restraining notices against the Restrained 15 Entities because, with one possible exception, the Restrained Funds are not “used for commercial activity in the United States”; and (3) because the record does not provide an adequate basis to determine whether the IATA Funds are used for commercial activity in the United States and whether they belong to Grenada, we vacate the District Court’s denial of post-judgment discovery as to these funds, and remand for the District Court to reassess whether to permit further discovery, consistent with the Supreme Court’s decision in NML Capital and our decision today. If, upon remand, the District Court decides to allow discovery, and discovery reveals that the IATA Funds are indeed attachable under the FSIA, the District Court may then assess, in the first instance, whether and to what extent Ex-Im Bank may properly restrain those funds going forward.

This appeal is DISMISSED in part, the judgment and order of the District Court is AFFIRMED in part and VACATED in part, and the cause REMANDED. 
      
      . The waiver provision in the loan agreements states in relevant part:

      . The District Court entered an initial judgment in February 2007, granting Ex-Im Bank’s motion for summary judgment. Shortly thereafter, Ex-Im Bank moved the court to amend the judgment on the ground that it did not set forth the particularized amounts to which Ex-Im Bank was entitled. The March 2007 amended judgment entered in response to that motion grants Ex-Im Bank the following amounts: $21,586,057.38 owed from the default, $3,323,586.90 in prejudgment interest, $82,225.00 for attorneys' fees, and post-judgment statutory interest and costs.

      . The bulk of the Grynberg Funds which were owed to Freshfields was held in the District Court. When Grenada's Colorado counsel demanded that it be paid $3,500 from the Grynberg Funds for services rendered in connection with the Colorado action, however, Ex-Im Bank consented to the requested payment and that sum was disbursed.
     
      
      . The "Restrained Entities” are Princess Cruise Lines, Ltd., Cunard Cruise Line, MSC Cruises, Disney Cruise Line, Virgin Atlantic Airways, Delta Airlines, Inc., Caribbean Airlines Ltd., the International Air Transport Association (served at two addresses, one in New York and one in Washington, D.C.), BWIA International Airways Ltd., British Airways PLC, and the Mediterranean Shipping Company (USA) Inc.
     
      
      . The "Statutory Corporations” are the Grenada Airports Authority (“GAA”), the Grenada Solid Waste Management Authority, the National Water and Sewage Authority of Grenada, the Grenada Ports Authority, and Aviation Services of Grenada Ltd., which is a wholly-owned subsidiary of the GAA.
     
      
      . Pursuant to N.Y. C.P.L.R. 5240, the Statutory Corporations are “interested parties,” with independent standing to challenge the restraining notices. For this reason, they are identified in the caption of this matter as Interested-Third-Party-Appellees.
     
      
      . The District Court observed that Grenada waived sovereign immunity from attachment and execution in the loan agreement with Ex-Im Bank. Grenada, 876 F.Supp.2d at 265.
     
      
      . As relevant here, section 1610 provides:
      (a) The property in the United States of a foreign state, as defined in section 1603(a) of this chapter, used for a commercial activity in the United States, shall not be immune from attachment in aid of execution, or from execution, upon a judgment entered by a court of the United States or of a State after the effective date of this Act, if ... (1) the foreign state has waived its immunity from attachment in aid of execution or from execution either explicitly or by implication, notwithstanding any withdrawal of the waiver the foreign state may purport to effect except in accordance with the terms of the waiver....
      28 U.S.C. § 1610(a)(1). This provision is far narrower than that applicable to property belonging to an "agency or instrumentality of a foreign state." 28 U.S.C. § 1610(b). Under section 1610(b), a party may execute against “any property” belonging to the agency or instrumentality, regardless of its use, as long as the agency or instrumentality is "engaged in commercial activity in the United States.” Id. (emphasis added). Neither party argues that section 1610(b) applies to any of the Statutory Corporations here.
     
      
      . The letter was transmitted by Jack B. Tate, Acting Legal Adviser at the State Department, to Philip B. Perlman, Acting Attorney General. See Letter of Jack B. Tate, Acting Legal Adviser, Department of State, to Acting Attorney General Philip B. Perlman (May 19, 1952), reprinted in 26 Dep't State Bull. 984-85 (1952); see also Samantar, 560 U.S. at 312-13, 130 S.Ct. 2278; App’x 2 to Opinion of the Court in Alfred Dunhill of London, Inc. v.

      . This feature was also consistent with the international legal backdrop for Congress's enactment of the FSIA:
      [In passing the FSIA,] Congress sharply restricted immunity from execution against agencies and instrumentalities, but was more cautious when lifting immunity from execution against property owned by the State itself. Congress passed the FSIA on the background of the views of sovereignty expressed in the 1945 charter of the United Nations and the 1972 enactment of the European Convention, which left the availability of execution totally up to the debtor state, and its own understanding as the legislative history demonstrates, that prior to 1976 property of foreign states was absolutely immune from execution.... It is plain then that Congress planned to and did lift execution immunity [only] "in part.” ... [S]ince it was not Congress’ purpose to lift execution immunity wholly and completely, a right without a remedy does exist [in certain contexts].
      
        De Letelier, 748 F.2d at 799.
     
      
      . Like the District Court, our Court declined to stay vacatur of the restraining notices and thus allowed Grenada to re-acquire and then disburse the Grynberg Funds to Freshfields. It may seem unfair to show litigants to the exit because we tore up their entry ticket, but such considerations cannot alter our conclusion here. As a jurisdictional matter, we cannot hear a case that does not present a live case or controversy. We note our concern, however, about treating as purely "commercial use’’ the expenditure of funds for securing representation in legal proceedings. This concern, among others, might have weighed here in favor of denying the motion to stay disbursement, as to which Ex-Im Bank bore the burden.
     
      
      . Although the restraining notices were lifted when we denied Ex-Im Bank’s stay request, the attachability of the Restrained Funds, unlike the dispute regarding the Grynberg Funds, is not moot. The Restrained Funds are part of several streams of payments made to the Statutory Corporations by the Restrained Entities. Were we to conclude that these funds are not immune from execution under the FSIA, the funds from this stream would be as amenable to attachment as they were before we denied the stay, and Ex-Im Bank could still seek to attach them.
     
      
      . The FSIA defines "commercial activity” as "either a regular course of commercial conduct or a particular commercial transaction or act.” 28 U.S.C. § 1603(d). It instructs that "[t]he commercial character of an activity shall be determined by reference to the nature of the course of conduct or particular transaction or act, rather than by reference to its purpose.” Id. The phrase "commercial activity” is used in several of the Act’s sections, including sections 1605 (the jurisdictional-immunity provision at issue in Welt-over) and 1610 (the attachment-immunity provision at issue here).
     
      
      . Notably, the Weltover Court did not have occasion to address immunities from attachment and execution under section 1610. Rather, its analysis was directed at the FSIA’s jurisdictional-immunity provision, section 1605(a)(2). We nonetheless find the Weltover Court’s analysis helpful in construing section 1610.
     
      
      . As did the District Court, we assume for the purpose of this analysis that the Statutory Corporations are Grenada’s alter egos, and therefore are liable for the judgment against Grenada even though they were not themselves signatories to the loan agreements. See Grenada, 876 F.Supp.2d at 267. The validity of this assumption need not be addressed here — we find the bulk of the Restrained Funds immune in any event.
     
      
      . We need not decide today the exact contours of the phrase “used for a commercial activity” under the FSIA. But our Court has previously opined that "[e]ven if actual use were not required” for attachment under section 1610(a), “at least specific designation ... would be necessary.” EM I, 473 F.3d at 485.
     
      
      . Because we conclude that the Restrained Funds are not subject to attachment, we need not reach Grenada’s argument that the restraining notices should have been lifted because they were issued before Ex-Im Bank obtained court approval to impose them. Grenada argues that the notices were issued in violation of 28 U.S.C. § 1610(c), which provides that no "attachment [of] or execution [on the property of a foreign state or its agencies or instrumentalities] ... shall be permitted until the court has ordered such attachment and execution.”
     
      
      .IATA is incorporated in Canada, but apparently has U.S.-based operations: as noted above, Ex-Im Bank served its restraining notices on IATA at its offices in New York and Washington, D.C. See J.A. 506-13.
     
      
      . It appears that Ex-Im Bank was not permitted to depose GAA’s George.
     
      
      . Both of these decisions issued after the District Court’s discovery ruling in the present case.
     
      
      . In arriving at this conclusion, we expressly rejected the Seventh Circuit's requirement that a judgment creditor identify specific non-immune assets before it is entitled to further discovery about those assets. See Rubin v. Islamic Republic of Iran, 637 F.3d 783, 796 (7th Cir.2011).
     
      
      . Indeed, as we observed in EM II, although a district court “has broad discretion to limit discovery in a prudential and proportionate way,” discovery in aid of execution "is the norm in federal and New York state courts.” 695 F.3d at 207.
     
      
      .In this regard, we note that IATA, like the third-party banks subject to the subpoenas duces tecum in NML, is acting in connection with its relationship to the GAA, but is entirely distinct from the sovereign itself. Thus, as we stated in EM II, the discovery was directed against entities "that ha[d] no claim to sovereign immunity, or to any other sort of immunity or privilege.” 695 F.3d at 210. The FSIA immunity concerns that, pre NML, might have contributed to the District Court’s denial of discovery, are therefore now even more attenuated.
