Plaintiffs-appellants John R. D’Alessio and his wholly owned company D’Alessio Securities, Inc. (collectively “D’Alessio”) appeal from the September 29, 2000 judgment of the United States District Court for the Southern District of New York, Rakoff, /., dismissing the complaint against defendants-appellees the New York Stock Exchange, Inc., Richard A. Grasso, Edward A: Kwalwasser and Robert J. McSweeney (collectively the “NYSE”) 1 on the ground that the NYSE enjoyed absolute immunity from a suit seeking monetary damages arising from the NYSE’s allegedly improper exercise of the regulatory and adjudicatory functions delegated to it under the Securities Exchange Act of 1934, as amended (Exchange Act). Because we conclude that the district court had jurisdiction over the present action and that the NYSE is entitled to immunity from suits for damages that arise out of its conduct as alleged in the complaint, we affirm the judgment of the district court in its entirety.
BACKGROUND
The district court set forth in detail the facts relevant to this dispute in its opinion and order,

In
Barbara v. New York Stock Exch.,
The [NYSE] is a nonprofit New York corporation registered with the [SEC] as a national securities exchange pursuant to section 6 of the [Exchange Act], 15 U.S.C. § 78f. As an association of securities dealers, the [NYSE] authorizes its members to effectuate securities transactions on its auction market, known as the [NYSE] floor. Under the [Exchange] Act, the [NYSE] is a “self-regulatory organization [ (SRO) ],” see 15 U.S.C. § 78c(a)(26), which means that it has a duty to promulgate and enforce rules governing the conduct of its members, see id. §§ 78f(b), 78s(g). These rules are subject to SEC approval. See 15 U.S.C. § 78s(b). In accordance with the statutory scheme, the [NYSE] conducts disciplinary proceedings when a member, or a person associated with a member, is suspected of violating federal securities laws or internal [NYSE] rules or regulations. See Id. § 78f(d). The [Exchange] Act requires that these disciplinary proceedings be conducted in compliance both with the [Exchange] Act and with the [NYSE’s] rules and regulations. See Id. § 78s(g)(l). Notice of any final disciplinary sanction imposed by the [NYSE] must be provided to the SEC, see id. § 78s(d)(l), and the imposition of a sanction is subject to review by the SEC on its own motion or at the instance of an aggrieved party, see id. § 78s(d)(2).

The instant appeal arises out of investigations conducted by the SEC and the United States Attorney’s Office targeting groups of independent floor brokers, commonly referred to as “$2.00 brokers,” who regularly execute trades on the NYSE floor. The government suspected some of these brokers of violating section 11(a) of the Exchange Act and SEC Rule lla-1 promulgated thereunder, as well as various rules of the NYSE,
2
“by engaging in illegal
*97
schemes of trading on the NYSE floor while sharing in the profits or losses generated from those trades.”
In re N.Y. Stock Exch.,
Exchange’ Act Release No. 34-41574,
The mechanics of the trading scheme were not complicated: D’Alessio would purchase a particular security on behalf of a customer and thereafter sell that same security at a higher price, resulting in a net gain for the customer. D’Alessio received as a commission a percentage of the profits generated on these “flip” trades based on the spread between the bid and ask prices for the securities, typically one-eighth of a point on each share of stock. D’Alessio’s exact share was determined by the individual agreements that he maintained with his customers. While there was no guarantee that these “flip” trades would result in a profit, as a floor broker, D’Alessio enjoyed a distinct advantage over other market participants because he had access to information regarding the performance of a particular security and the direction of its share price.
As a result of these activities, in February 1998, the United States Attorney’s Office indicted D’Alessio for willfully violating various statutes and regulations that prohibited a floor broker from trading for his own account or for an account in which he exercised investment discretion. The SEC and the NYSE brought parallel charges against D’Alessio arising out of the same conduct. Specifically, the government charged D’Alessio with illegally sharing in the profits generated by trades he executed on the floor of the NYSE on behalf of Oakford.

See D’Alessio,
In December 1999, D’Alessio, personally, and his company, D’Alessio Securities, Inc., commenced an action against the NYSE in the Supreme Court of New York, New York County, alleging that the NYSE and various senior officials employed by the NYSE conspired to violate applicable statutory and regulatory prohibitions governing unlawful trading, to wit, section 11(a), Rule lla-1 and various rules of the NYSE, by “concoct[ing] a phoney interpretation” of these provisions and knowingly disseminating that incorrect interpretation to the detriment of D’Alessio and other floor brokers. D’Alessio contends that he relied on the NYSE’s interpretation at the time he engaged in trading practices that were later determined to be illegal. D’Alessio alleges that the NYSE, in an effort to keep its activities secret and curry favor with law enforcement authorities, assisted the United *98 States Attorney’s Office and the SEC in their investigation and prosecution of D’Alessio by providing them with “false, misleading and inaccurate information about ... D’Alessio.” D’Alessio further alleges that the NYSE failed to disclose to these authorities that it had “approved and encouraged the practice of flipping,” the specific type of unlawful trading for which D’Alessio had been charged. D’Alessio attributes the NYSE’s inaction to the substantial fees earned by the NYSE and clearing members on the high volume of “flipped” trades and “a desire to increase the daily volume of trading activity on the NYSE.” D’Alessio contends that, as a result of the NYSE’s alleged misconduct, he has incurred legal difficulties and has been unable to work as a floor broker on the NYSE.
Based on these and related allegations, D’Alessio brought numerous tort claims against the NYSE and its various officers for injurious falsehood and concealment, fraudulent deceit and concealment, negligent misrepresentation and concealment, and, as to the NYSE only, breach of contract. In connection with these claims, D’Alessio sought compensatory and punitive damages.
On January 13, 2000, the NYSE filed a notice of removal of the action to the United States District Court for the Southern District of New York pursuant to 28 U.S.C. § 1441. Notably, D’Alessio did not challenge removal of the action to federal court at that time or otherwise challenge the district court’s jurisdiction over the action. Indeed, the issue of federal jurisdiction was not raised until the district court raised it
sua sponte
in a related case also before the district court.

See Frayler v. N.Y. Stock Exch.,
DISCUSSION
The present appeal raises two questions: first, whether the instant action implicates a federal interest sufficient to sustain removal of the action to federal court, and second, “whether employees of the [NYSE] who, pursuant to statutory delegation, perform regulatory functions that would otherwise be performed by the [SEC] are entitled to the same immunities from suit to which comparable [SEC] employees would be entitled.” Id. at 657. The district court answered both questions in the affirmative. We agree, and therefore affirm the district court’s decision.
A. Standard of Review
“When reviewing a district court’s determination of its subject matter jurisdiction, we review factual findings for clear error and legal conclusions
de novo.” Phillips v. Saratoga Harness Racing,
B. Whether a Substantial Federal Interest Exists
Before we address the merits of the NYSE’s claim of immunity from suit, we first must consider whether the action was properly removed to federal court.
Pursuant to 28 U.S.C. § 1441(b), a state court defendant may remove a case to federal court “only if the plaintiffs claims could originally have been brought there.”
Barbara,
The determination of whether a claim “arises under” federal law — or, as in the present case, whether removal jurisdiction existed — is “determined by reference to the ‘well-pleaded complaint.’ ”
Merrell Dow,
Each of the four causes of action in D’Alessio’s state court complaint alleges claims under the common law of the state of New York. This point is undisputed by the parties. ■ D’Alessio argues that a finding that federal jurisdiction is lacking is mandated by our prior decision in Barbara, in which we held improper the removal of an action challenging the propriety of internal disciplinary proceedings conducted by the NYSE. In response, the NYSE argues that removal was proper because the federal issues underlying D’Alessio’s state law claims are sufficiently substantial to confer federal-question jurisdiction. These federal issues include the interpretation and application of the federal securities laws and the statutory requirement that the NYSE ensure that its members comply with the securities laws and exchange rules, areas of undisputed strong federal interest. Because the parties rely heavily on Barbara to support their respective positions, we briefly outline the relevant facts of that case.
In
Barbara,
the SEC initiated an investigation into alleged misconduct by Barbara, a floor clerk at the NYSE, and his employer, Mabon, Nugent Securities.
Barbara commenced an action in state court alleging state law claims for, inter *101 alia, tortious interference with contractual relationships, tortious interference with prospective economic advantage, negligent supervision and breach of the covenant of fair dealing within an implied contract. Id. The NYSE removed the action to federal court, which Barbara apparently did not challenge. On motion of the NYSE, the district court dismissed Barbara’s suit on the ground that he failed to exhaust his administrative remedies. Id. at 53. On appeal, we raised the question of subject matter jurisdiction sua sponte, and held that Barbara’s claims were insufficiently substantial to “arise under” federal law within the meaning of section 1331. Our holding rested primarily on two factors: first, the absence of a private right of action under the applicable federal statute “counsel[ed] against a finding of federal question jurisdiction,” id. at 54, and second, the claims raised by Barbara in his complaint involved the internal rules of the NYSE, which are contractual in nature, and “thus interpreted pursuant to ordinary principles of contract law, an area in which the federal courts have no special expertise.” Id. at 55. We nevertheless sustained the district court’s subject matter jurisdiction over the action based on Barbara’s amended complaint, which alleged violations of federal law. Id. at 56.
We find the facts present in this case distinguishable from those in Barbara, and conclude that the instant suit implicates a federal interest sufficiently substantial to confer subject matter jurisdiction under section 1331.
In Barbara, the plaintiffs claims required the district court to determine whether disciplinary proceedings initiated by the NYSE were consistent with its own internal rules and its contractual obligations to its members. As such, the claims required an examination of the various internal rules of the NYSE in accordance with well settled principles of contract interpretation — a task uniquely within the province of state law.
In contrast, here, the federal interest is more substantial because D’Alessio’s complaint does not simply challenge the propriety of disciplinary proceedings conducted by the NYSE. D’Alessio concedes this distinction, stating “the Complaint makes no allegations about disciplinary proceedings at all.” Rather, an examination of the allegations contained in the complaint establishes that D’Alessio’s suit is rooted in violations of federal law, which favors a finding that federal question jurisdiction exists. Specifically, the gravamen of D’Alessio’s state law claims is that the NYSE and its officers conspired to violate the federal securities laws and various rules promulgated by the NYSE and failed to perform its statutory duty,
created under federal law,
to enforce its members’ compliance with those laws.
5
See, e. g., Sable v. Gen. Motors Corp.,
This determination compels our resolution of the question of jurisdiction: because the NYSE’s alleged violations of the federal securities laws and its improper interpretation of those laws underlie D’Alessio’s state law claims, the federal issue is substantial. “[U]pon [the federal statute’s] construction the vindication of
*103
rights and definition of relationships
created by federal law
depends.”
W. 14th St. Commercial Corp.,
Our conclusion in favor of federal jurisdiction is bolstered by allegations in the complaint of malfeasance on the part of the NYSE in the performance of its general oversight function. Specifically, D’Alessio alleges that the NYSE failed to satisfy its “duty to its members to abide by and enforce its rules, and to accurately advise its members with respect to the securities laws and regulations and its own rules.” This duty is imposed on the NYSE by sections 19(g) and 19(h) of the Exchange Act,
see
15 U.S.C. §§ 78s(g), (h);
In re N.Y. Stock Exch.,
While D’Alessio’s claims are cast as state law claims, they are premised, in large part, on the NYSE’s failure to enforce and monitor compliance by its members with the Exchange Act and the rules and regulations thereunder, as well as the rules promulgated by the NYSE pursuant to the Exchange Act.
See id.
at *1 (“Exchanges violate Section 19(g) when they fail to be vigilant in surveilling for, evaluating, and effectively addressing issues that could involve violations of the securities laws.”) (internal quotation marks omitted). The source of the duty imposed on the NYSE (as well as other SROs) is found in
federal
law; namely, in the Exchange Act. Thus, it is the propriety of the NYSE’s actions, as prescribed under federal law, that is at the heart of D’Alessio’s allegations. Moreover, resolution of D’Alessio’s claims necessarily requires an inquiry into whether the NYSE satisfactorily performed its duty in identifying potential violations of the federal securities laws and assisting in any criminal or civil investigation arising from a member’s noncompliance with those laws, both areas of strong federal interest.
See, e. g., Barbara,
C. Whether the NYSE and its Officials Enjoy Absolute Immunity From Suit
Having determined that removal was proper, we proceed to the second inquiry: whether the NYSE and its officers possess absolute immunity with respect to D’Alessio’s claims. Because the facts relevant to the question of immunity are undisputed and clearly set forth in the record, we decide that question as a matter of law, based on the allegations contained in the complaint.
See Austin Mun. Sec. v. Nat’l Ass’n of Sec. Dealers,
The NYSE argues that it is absolutely immune from suit because the allegations in the complaint are predicated on the NYSE’s improper performance of the regulatory functions delegated by the SEC to the NYSE pursuant to the Exchange Act. In response, D’Alessio argues that the district court’s dismissal of the complaint on absolute immunity grounds was based on an “erroneous expansion” of our decision in
Barbara,
which accorded the NYSE immunity from suit in a case involving alleged misconduct in connection with internal disciplinary proceedings. Specifically, D’Alessio argues that, unlike
Barbara,
“the misconduct alleged in the instant lawsuit also includes improper interpretations of federal securities laws and allegedly duplicitous conduct in connection with providing information about plaintiffs to the [SEC] and the U.S. Attorney’s Office.” D'Al
essio,
As in our resolution of the jurisdiction question, we begin with the specific facts and holding in
Barbara.
In
Barbara,
we upheld the district court’s decision according absolute immunity to the NYSE for “claims arising out of the performance of its federally-mandated conduct of disciplinary proceedings.”
The NYSE, as a SRO, stands in the shoes of the SEC in interpreting the securities laws for its members and in monitoring compliance with those laws. It follows that the NYSE should be entitled to the same immunity enjoyed by the SEC when it is performing functions delegated to it under the SEC’s broad oversight authority.
See Sparta Surgical Corp.,
In determining whether the NYSE is entitled to absolute immunity from suit in the present case, we look not
*106
at the manner in which D’AIessio casts his claims against the NYSE (ie., tort or contract), but rather to the alleged misconduct of the NYSE as detailed in the complaint. D’Alessio’s claims are predicated on the NYSE’s improper performance of its interpretive, enforcement and referral functions. Specifically, D’Alessio alleges that the NYSE incorrectly interpreted and applied section 11(a) of the Exchange Act and regulations and rules thereto (interpretive function); that the NYSE failed to monitor D’Alessio’s compliance with the Exchange Act and various rules of the NYSE, and advise him that the commissions he earned in connection with “flip” trades violated those laws (enforcement function); and that the NYSE provided false information when it cooperated with and assisted the United States Attorney’s Office and the SEC in their investigations into alleged violations of section 11(a) by D’Alessio and other floor brokers (referral function). The district court concluded that the NYSE’s actions fell “well within the perimeter of the [NYSE’s] quasi-governmental duties” because they “relate to the [NYSE’s] development and promulgation of interpretations of statutory and regulatory requirements, the dissemination and implementation of these interpretations, and the provision of information to government agencies.”
D’Alessio,
The NYSE’s alleged improper interpretation of the type of conduct prohibited under section 11(a) falls within the NYSE’s “quasi-public adjudicatory” duties. Similarly, the NYSE acted in its adjudicatory capacity when it determined that D’AIessio was guilty of violating section 11(a) and various rules of the NYSE and suspended him from further trading on the NYSE floor. Because these actions “share the characteristics of the judicial process,”
Barbara,
CONCLUSION
For the foregoing reasons, we affirm the district court’s grant of judgment on the *107 pleadings in favor of the NYSE and its various officers. The parties shall bear their own costs on this appeal.
Notes
. At all relevant times, Grasso was the Chairman of the NYSE, Kwalwasser was a Group Executive Vice President of the NYSE, responsible for Market Surveillance, Enforcement and Member Firm Regulation, and McSweeney was a senior Vice President of the NYSE in charge of the Market Surveillance division.
. Section 11(a) provides, in pertinent part, that "[i]t shall be unlawful for any member of a national securities exchange to effect any transaction on such exchange for its own account, the account of an associated person, or an account with respect to which it or an associated person thereof exercises investment discretion.” 15 U.S.C. § 78k(a)(l). Rule 1 la-1, which regulates floor trading, provides, in pertinent part, that [n]o member of a national securities exchange, while on the floor of such exchange, shall initiate, directly or indirectly, any transaction in any security admitted to trading on such exchange, for any account in which such member has an interest, or for any such account with respect to which such member has discretion as to the time of execution, the choice of security to be bought or sold, the total amount of any security to be bought or sold, or whether *97 any such transaction shall be one of purchase or sale.
17 C.F.R. § 240.11a-1. The NYSE has promulgated similar rales, cited by D'Alessio throughout his complaint, barring these and similar practices. See NYSE Rules 90(a); 91; 92(a); 95; 111(a); and 352(c).
. Under his profit sharing agreement with Oakford, D’Alessio received 70% of the trading profits for trades he executed on behalf of the Oakford account.
. The district court analyzed the question of federal jurisdiction over D'Alessio’s claims in a separate action,
Frayler v. N.Y. Stock Exch.,
. D'Alessio apparently conceded this point below. In characterizing D’Alessio's arguments, the district court stated:
[D’Alessio] seek[s] to distinguish Barbara from the instant lawsuit in several respects. First, [D’Alessio] note[s] that while Barbara involved misconduct in connection with disciplinary proceedings, the misconduct alleged in the instant lawsuit also includes improper interpretations of federal securities laws and allegedly duplicitous conduct in connection with providing information about plaintiffs to the [SEC] and the U.S. Attorney's Office.
D’Alessio,
. A cursory examination of the complaint demonstrates that D'Alessio's claims are predicated on alleged breaches of certain duties imposed on the NYSE under the Exchange Act in its capacity as a SRO. Specifically, the allegedly untrue statements made by the NYSE to the government in connection with its investigation into D'Alessio's trading activities form the basis of D'Alessio’s injurious falsehood claim.
