Wе are called upon to decide whether the district court had personal jurisdiction over an Austrian bank. The district court granted a motion to dismiss under Fed.R.Civ.P. 12(b)(2) for lack of jurisdiction. We reverse.
I.
Appellant Elizabeth Ballard (“Ballard”) brought this class action lawsuit on behalf of herself and other victims of an alleged Ponzi scheme in which investors were promised a $10 million return for every $5,000 they invested. Known as the “Savage Program” after its fоunder and chief perpetrator Michael Savage, the bogus scheme took in millions of dollars before its eventual demise. 1 This action represents Ballard’s effort to recover some of the money she and her fellow victims lost.
Only one defendant to Ballard’s class action is involved in this appeal. That defendant is Royal Trust Bank (“Royal” or the “Bank”), an Austrian bank headquartered in Vienna. Ballard alleges in her comрlaint that Royal was a knowing participant in the Savage Program. According to Ballard, the Bank’s role in the scheme was to take the ill-gotten money and hide it in Austria where it would remain beyond the reach of the American legal process when the fraud surfaced. She claims that Royal, among other things, lent its good name to the scheme to mislead investors into believing that Mr. Savage was running a legitimate business. For proof, she points to documents on Royal letterhead touting the Savage Program as a legitimate business venture. She also claims that Royal refunded $12,000 to a disgruntled investor from its own checking account at National Westminster Bank in New York. That Royal used its own funds to pay the refund presumably tends to show that Royal actively helped to cover the criminal tracks of Michael Savage and his cohorts.
Not surprisingly, Royal paints a very diffеrent picture of this case and its involvement in the Savage Program. It admits a limited relationship with Michael Savage, but claims that it was at most an innocent repository of funds generated by a criminal enterprise. It denies any allegation that it participated in the scheme to defraud American investors. As for the documents on Royal letterhead, the Bank claims that Mr. Savage forged them without its knowledge. Royal also рoints out that it assisted federal author *1497 ities in the criminal investigation of Mr. Savage and even sent an employee to testify against him at trial. Royal further notes that it never has been charged with any wrongdoing by American or Austrian authorities.
The dispute over Royal’s involvement in the Savage Program was never resolved. In the very early stages of the litigation, the district court granted Royal’s motion under Fed.R.Civ.P. 12(b)(2) to dismiss the case against it for want of personal jurisdiction. A final judgment dismissing the ease was entered pursuant to Fed.R.Civ.P. 54(b). Ballard appeals the dismissal, arguing that the district court had both general and specific jurisdiction over the defendant Bank. We have jurisdiction of her appeal pursuant to 28 U.S.C. § 1291.
II.
Many of the jurisdictional facts of this case are disputed, but this much is clear. Royal is an Austrian Bank organized and regulated under Austrian law. 2 Its principal place of businеss is in Vienna. It has no offices or employees in the United States, nor does it generally advertise or solicit business here. Royal does, however, depend on the United States for a substantial amount of its business. In 1992-98, for example, 8,500 of its approximately 5,700 depositors (some 60 percent) were U.S. residents or had U.S. mailing addresses. Royal also regularly extends loans to customers in the United States; in the most recent time period for which figures are available, approximately 13 percent of Royal’s outstanding loans were held by U.S. residents. 3 The aggregate dollar value of these loans ranged from a low of $3.3 million in 1988 to a high of $7.5 million in 1990. It appears that these loans are negotiated in Austria, governed by Austrian law, and fully collateralized by assets located in Austria. Royal has therefore argued that it “should never have to file suit [in the United States] in order to сollect on the loans or otherwise enforce [its] rights” with respect to these loans.
Although Royal claims not to advertise in the U.S., it admits that it does send prospective U.S. customers information about the Bank at their request. Royal also admits that it at least occasionally solicits new business from its existing U.S. customers by sending them promotional materials along with their regular account statements. In addition, Royal employees appear to be frequent visitors to the United States. Between 1989 and 1993, Royal officials made at least 24 separate business trips to the United States and California to meet with customers, attend conferences and seminars, and the like.
Royal also maintains brokerage accounts in New York and New Jersey. It uses these accounts to trade millions of dollars per year in the U.S. securities markets. It also has “corrеspondent accounts” at several U.S. banks. The parties dispute the purpose of these accounts, but it seems clear that at least one purpose is to simplify Royal’s banking relationship with its U.S. customers. For example, an individual in Los Angeles who in 1991 wished to make a deposit in his Royal account could have walked down to a local branch of Union Bank, deposited $100,000 in Royal’s correspondent accоunt there, and had the money quickly posted to his account at Royal.
The question we must address is whether these contacts are sufficient to support an exercise of personal jurisdiction over Royal. The district court answered that question in the negative. Unfortunately, however, it made no factual findings to support its decision. Instead of holding an evidentiary hearing at which the parties could hash out the facts, the district court elected to consider *1498 the motion to dismiss on the basis of the written materials submitted by the parties.
When a district court acts on a defendant’s motion to dismiss under Rule 12(b)(2) without holding an evidentiary hearing, the plaintiff need make only a prima facie showing of jurisdictional facts to withstand the motion to dismiss.
See Pacific Atlantic Trading Co. v. M/V Main Exp.,
III.
We begin with the question of specific jurisdiction. We use a three-part test to determine whether the district court may exercise specific jurisdiction over a nonresident defendant:
(1) The nonresident defendant must do some act or consummate some transaction with the forum or perform some act by which he purposеfully avails himself of the privilege of conducting activities in the forum, thereby invoking the benefits and protections^] (2) [t]he claim must be one which arises out of or results from the defendant’s forum-related activiües[; and] (3) [e]xercise of jurisdiction must be reasonable.
Omeluk v. Langsten Slip & Batbyggeri A/S,
A.
An exercise of specific jurisdiction is appropriate only if the nonresident defendant hаs “purposefully avail[ed] itself of the privilege of conducting activities within the forum State, thus invoking the benefits and protections of its laws.”
Burger King Corp. v. Rudzewicz,
Royal’s actual physical contacts with the United States and California are quite limited. As far as the record reveals, they consist of the 24 business trips Bank officials have taken here. However, these physical contacts of themselves do not weigh in favor of an exercise of specific jurisdiction, because Ballard’s case against the Bank does not concern the Bank’s business trips to Amer-ica.
See Haisten,
It is undisputed, however, that the Bank has created numerous ongoing obligations to U.S. residents. As notеd, more than 60 percent of its customers live in the United States. U.S. residents also are the beneficiaries of millions of dollars of Royal loans. The Bank regularly mails account statements to its U.S. customers, and it at least occasionally solicits new business from them. It also maintains “correspondent accounts” at several major U.S. financial institutions. At least one purpose of these accounts is to give Royal all оf “the accessibility of your home bank.”
Royal generally does not dispute these contacts. We conclude that the contacts are more than sufficient to establish “purposeful availment.” Our opinion in
Haisten
is particularly instructive. There, we faced the question of whether a federal
*1499
court in California had specific jurisdiction over a Cayman Islands insurance company.
See
In
Hirsch
we also addressed the question of specific jurisdiction over a nonresident insurance company. There, a Kansas insurance company with no physical ties to California agreed to insure the employees of a Kansas trucking company.
Finally, we take note of the Third Circuit’s decision in
Provident Nat’l Bank v. California Fed. Sav.
&
Loan,
The cases Royal cites are not to the contrary. Its reliance on
Oriental Imports & Exports v. Maduro & Curiel’s Bank,
The same goes for the decision in
E.I.C., Inc. v. Bank of Virginia,
108 Cal.
*1500
App.3d 148,
B.
We rely on a “but for” test to determine whether a particular claim arises out of forum-related activities and thereby satisfies the second requirement for specific jurisdiction.
See Shute v. Carnival Cruise Lines,
The question, therefore, is this: but for Royal’s contacts with the United States and California, would Ballard’s claims against the Bank have arisen? Ballard answers this question in the affirmative. She argues that if Royal had not done business in the United States, she would have no claim against it, because in the absence of Royal’s American banking network, Mr. Savage would not have opened an account at the Bank and filled it with ill-gotten funds. This logic seems sоund. Given that Royal does not dispute it, we conclude that Ballard has carried her burden on the issue.
C.
The third requirement is that an exercise of jurisdiction must be reasonable. We presume that an otherwise valid exercise of specific jurisdiction is reasonable.
See Sher v. Johnson,
1.
We first consider the extent to which Royal has purposefully availed itself of the privilege of doing business in the United States.
See Core-Vent Corp. v. Nobel Industries AB,
2.
We next consider the forum state’s interest in adjudicating this dispute.
See Haisten,
3.
We now consider whether an exercise of jurisdiction would conflict with Austria’s sovereignty. Although this factor is important,
see Asahi Metal Industry Co. v. Superior Court,
An exercise of jurisdiction over the Bank necessarily would implicate Austria’s sovereignty interest. See
FDIC v. British-American Ins. Co.,
Although we reject Royal’s invitation to declinе jurisdiction on the basis of “international comity,” we nevertheless agree with Royal and the district court that an exercise of jurisdiction would implicate Austria’s sovereignty interest. Accordingly, this factor weighs in Royal’s favor.
4.
Another important consideration is whether Royal will be burdened by having to come defend itself in California.
See Asahi,
5.
The next two factors are easy. We must consider (a) which forum could most efficiently resolve this disрute and (b) where Ballard *1502 could obtain the most effective and convenient relief. As the district court concluded, the most efficient resolution of this dispute would be in the Southern District, since the court there already is familiar with the facts and procedural history of the litigation. Also, Ballard could obtain the most effective and convenient relief in California, as the district court properly concluded. Id. Both of these factors weigh in Ballard’s favor.
6.
The final considеration is whether there exists an alternate forum. Royal claims that an Austrian court could hear Ballard’s claims, but it presents absolutely no evidence on this issue, erroneously assuming that the burden is on Ballard to prove the lack of an alternate forum. Although we assume that Austria would provide Ballard some sort of forum, whether the forum would be adequate is impossible to say on the record as it now stands. This factor weighs in Ballard’s favor.
In fine, Royal has not carried its heavy burden of presenting a “compelling case” against jurisdiction.
See Burger King,
REVERSED and REMANDED.
Notes
. Mr. Savage was the subject of a successful criminal prosecution in the Northern District of California. See United States v. Savage, CR-93-10667.
. Royal is owned and operated by Royal Trustco, Ltd., a Canadian company that operates several banks in Austria, Canada, Great Britain, and other foreign countries.
. According to Royal, all of its loans to U.S. customers are so-called "Lombard loans" and are fully secured by assets within the Bank’s control. The purpose of a Lombard loan is to allow a customer to make a cash investment through the Bank without having to sell a certificate of deposit before its maturity date or unload securities at an inopportune time.
. California permits its courts to exercise personal jurisdiction to the extent permitted by the federal due process clause.
See Hirsch,
. The burden is on Royal to show that jurisdiction would be unreasonable.
