Plaintiffs, five chiropractors engaged in private practice in Virginia and West Virginia, brought this action under the Sher*814man Antitrust Act, 15 U.S.C. §§ 1 and 2,1 for damages and injunctive relief. Named as defendants were the Virginia Chiropractors Association (VCA), its president, the American Chiropractic Association (ACA), three health insurance companies and five individual chiropractors, formerly serving on the Peer Review Committee of VCA. The accusations arose out of the structure of the peer review system. Defendants’ motions to dismiss were rejected;2 they appeal; we reverse.
Peer Review’s duties include pursuing inquiries from insurance companies. Upon receiving a bill for chiropractic services from an insured patient, an insurance company may submit the statement to the Committee. The latter then ascertains for the insurers the usual and customary charges for such attention, referring therefor to a schedule of rates considered fair and reasonable by the ACA and the VCA;3 the amount so ascertained is then remitted to the insured by the insurer. Mechanisms for reviewing decisions of each State Peer Review Committee throughout the country are furnished by the ACA.
Plaintiffs, non-members of VCA, complained that the Peer Review process constituted a conspiracy between the chiropractic associations and the insurance companies to fix prices, thereby monopolizing the practice of chiropractic. The alleged price fixing stems from the ceiling imposed by the Committee on the usual and customary charge for an office visit. This ceiling is the maximum amount compensable by insurance but is apparently not adequate to compensate plaintiffs for various additional or intensive treatments they may perform during the course of an office visit. The effect, plaintiffs argue, is a boycott. Defendants have, it is asserted, refused to deal with them regarding services provided and billed in excess of the maximum for a single visit. Plaintiffs’ claim is that the conspiracy also extends to coercing their patients into seeking treatment elsewhere. In order to increase the percentage of their bills reimbursable by insurance, patients will seek the services of chiropractors who have adapted their charges to the ACA and VCA fee schedule. Thus, plaintiffs assert that they are coerced and intimidated into accepting VCA’s pricing rituals.
Ancillary State claims have, at the same time, been asserted against the defendants for interference with plaintiffs’ contractual relations with their prospective patients, as well as for libel and slander of plaintiffs’ professional practice.
In response, the ACA initially moved to dismiss the suit for lack of venue, pleading Des Moines, Iowa as its domicile, and asserting that it was not present or transacting business in Virginia.4 All defendants have moved for dismissal under Fed.R. Civ.P. 12(b)(6) or for summary judgment under Fed.R.Civ.P. 56, on the ground that the McCarran-Ferguson Act5 exempted them from the antitrust laws, because they were in “the business of insurance”6 with no conduct amounting to “boycott, coercion, *815or intimidation.”7 They further moved to dismiss the ancillary State claims for lack of jurisdiction in the event that the Federal antitrust claim was dismissed.
The District Court denied all the motions. Upon defendants’ interlocutory appeal8 (perfected only as to the antitrust claims), we reverse.
I. ACA: IMPROPER VENUE
Venue for this action is delineated in Section 12 of the Clayton Act in these terms:
Any suit, action, or proceeding under the antitrust laws against a corporation may be brought not only in the judicial district whereof it is an inhabitant, but also in any district wherein it may be found or transacts business; and all process in such cases may be served in the district of which it is an inhabitant, or wherever it may be found.
15 U.S.C. § 22.
Admittedly, ACA was neither an “inhabitant” of Virginia, nor could it be “found” there. Yet, contrary to appellants’ insistence, the District Court concluded that venue was proper in the Western District of Virginia as ACA “transacts business” in the State. Employing the familiar touchstone, the trial court examined whether ACA engaged in “[t]he practical, everyday business or commercial concept of doing or carrying on business ‘of any substantial character.’ ” United States v. Scophony, 333 U.S. 795, 807, 68 S.Ct. 855, 862, 92 L.Ed. 1091 (1948). See Eastman Kodak Co. v. Southern Photo Materials Co., 273 U.S. 359, 373, 47 S.Ct. 400, 71 L.Ed. 684 (1927). It framed the character of the national association’s operations as follows:
The ACA ... is not a commercial, profit-making organization whose business can be described by sales and purchases, but is a non-profit organization whose activities are described as educational and informative in nature directed toward advancement of the chiropractic profession, the improvement of chiropractic performance and toward better understanding of the profession by the public, insurers, and government. Public relations and professional advancement are its “business.” (Footnote omitted.)
Bartholomew v. Virginia Chiropractors Ass’n, 451 F.Supp. at 628-29.
Erroneously, however, in finding jurisdiction, the District Court accepted as decisive the following activity imputed to ACA by plaintiffs as disclosing its “transactpon of] business” in Virginia:
The plaintiffs have alleged that in furtherance of this “business” the ACA has solicited every commercial and educational radio and television station in Virginia for air time, and received air time, billboard space and newspaper space valued at more than $250,000 for the years 1974-1976. The ACA provided the radio and television recordings and films, which in 1976 cost $180,000 to prepare. These amounts are substantial and show a continuous solicitation of advertising time in this district in furtherance of defendant’s essential purpose, to supply information about the chiropractic profession. (Citations omitted.)
Id. at 629.
This recital must be tempered by the defendants’ answer to plaintiffs’ response to interrogatory No. 3:
(a) No cost has been incurred by ACA for the use of television, radio and newspapers in Virginia. However, the materials used by the mass media are prepared by ACA at its own cost, which, for the fiscal year April 1, 1976 to March 31, 1977, amounted to $180,000 nationally.
(b) The public service free time that ACA has succeeded in obtaining from the TV and radio media, and the free billboard and newspaper space that it has succeeded in obtaining from those media, has no market or commercial value for ACA. These public service educational programs prepared by ACA are devoted exclusively to educating the public as to the *816nature and problems of chiropractic treatment and the role of the chiropractic profession; as pointed out in 3(a), above, they operate at a loss to ACA. (Accent added.)
Notwithstanding that the burden is upon plaintiff to establish venue and jurisdiction, Call Carl, Inc. v. B P Oil Corp., 391 F.Supp. 367; 370 (D.Md. 1975), the quoted response was not traversed nor even attempted.
Enumeration of the points of contact ACA has with Virginia, even without limiting the discussion to the Western District, will entirely raze all imprint of its venue-presence. Virginia accounted for only 53 of the 8875 national members, .06 percent of its membership. ACA never qualified to do business in Virginia (only in Delaware) and its sole office was in Iowa. In Virginia, there were no offices, no officers, no agents, no property, no purchases, no seminars or workshops, and no sales save of pamphlets, journals, and other educational and public relations materials generating very little revenue. All transactions were by mail. No membership meetings were convened in Virginia; no directors or employees resided there.
ACA trained in Iowa the six chiropractors comprising peer review personnel for Virginia. Akin to its practice with all other State associations, ACA corresponded with VCA. It had not crossed into Virginia in perfecting its purposes or, as the District Judge observed, “to participate with the VCA peer review program.”
ACA’s solicitation of advertising time and its dissemination across Virginia boundaries of correspondence, informational materials, public service educational programs by mail, radio, television and newspaper (free of cost to ACA) was not transacting business in the State within the meaning of Section 12 of the Clayton Act, 15 U.S.C. § 22. Likewise the transmittal of such items into Virginia by mass media for subsequent telecasting, broadcasting or publishing was not within the Act’s domain. People’s Tobacco Co. v. American Tobacco Co., Ltd., 246 U.S. 79, 87, 38 S.Ct. 233, 62 L.Ed. 587 (1918); Golf City, Inc. v. Wilson Sporting Goods Co., Inc., 555 F.2d 426, 437-38 (5th Cir. 1977); Friends of Animals, Inc. v. American Veterinary Medical Ass’n, 310 F.Supp. 620, 624 (S.D.N.Y. 1970); Wentling v. Popular Science Publishing Co. Inc., 176 F.Supp. 652, 656-57 (M.D.Pa. 1959); Elizabeth Hospital, Inc. v. Richardson, 167 F.Supp. 155, 158-59 (W.D.Ark. 1958). Otherwise, every State in the Union into which such programs were aimed or thrust by media or mail would provide an acceptable forum for suit based on “transactpng] business” therein.
II. DEFENDANTS’ EXEMPTION FROM ANTITRUST LAWS
All of the defendants, even ACA, if it had been within the jurisdiction of the Court, were immunized from responsibility under the Sherman Act by the McCarranFerguson Act because they were engaged in the “business of insurance.”9 Each of them played a part in the peer review system and, thus, was in the business of insurance. Initially, before the trial court, plaintiffs conceded that the insurers — Metropolitan Life Insurance Company, The Aetna Casualty and Surety Company and The Travellers Insurance Company — were in the business of insurance when participating in the peer process. This concession has been withdrawn, but, nevertheless, in fact and in law, these companies were operating in that character.
*817The essence of the business of insurance is “the relationship between the insurance company and the policyholder.” SEC v. National Securities, Inc., 393 U.S. 453, 460, 89 S.Ct. 564, 569, 21 L.Ed.2d 668 (1969). Mindful of this precept, the analysis now following of the parts the defendants indisputably played demonstrates beyond question their engagement in the business of insurance:
1. To begin with, the companies issued policies of health insurance.
2. As aforesaid, the pattern was for the chiropractor to send his bill to the patient and he, in turn, passed it on to his own insurance carrier for indemnification or reimbursement by virtue of the patient’s insurance policy.
3. The insurance carrier thereupon submitted the bill to VCA for examination by the Peer Review Committee.
4. Payment was then made by the insurer to the patient-policyholder and not to the chiropractor, unless directed by the policyholder so to do. The patient received the amount approved by the Peer Review Committee according to the VCA fee schedule.
5. ACA’s participation was to adjust, if feasible, any monetary differences between the insurer and patient in an appeal process.
6. The ACA had from the beginning contributed its share in the business of insurance by consulting with the insurers to establish the schedule of allowable fees.
7. The sole parties to the system were the insured and the insurer. Cf. id.
Exuding throughout is evidence of a unitary thesis: each defendant’s activities touched upon “the business of insurance.” Incidentally, plaintiffs conceded that the insurer-defendants are regulated by the State, as contemplated in the McCarran Act’s grant of antitrust immunity to insurance companies.10 Bartholomew v. Virginia Chiropractors Ass’n, 451 F.Supp. at 626 (W.D.Va. 1978). Hence, the plan was well within even the straits of the Act.
This conclusion does not trespass upon the teachings of Group Life & Health Ins. Co. v. Royal Drug Co., 440 U.S. 205, 99 S.Ct. 1067, 59 L.Ed.2d 261 (1979). In that case there were two segregated and disparate operations: one, the offering of insurance, and the other, the procurement of drugs, admittedly an act only thinly tangential to insurance. Obtaining drugs under the Pharmacy Agreement was a business of the insurance companies, not the business of insurance. Royal Drug at 218, 99 S.Ct. 1067, n. 18. In the present instance, there is an integration of component acts resulting in a single, composite business-insurance. For an especially clarifying discourse of this and the related issues see generally Pireno v. New York Chiropractic Ass’n, No. 76-4309 (S.D.N.Y. March 15, 1979).
III. NO BOYCOTT
“Boycott” under the Sherman Act is a “concerted refusal to deal,” St. Paul Fire & Marine Insurance Co. v. Barry, 438 U.S. 531, 536, 98 S.Ct. 2923, 57 L.Ed.2d 932 (1978), quoting Barry v. St. Paul Fire & Marine Insurance Co., 555 F.2d 3, 8 (1st Cir. 1977); see Virginia Academy of Clinical Psychologists v. Blue Shield of Virginia, 469 F.Supp. 552, 563 (E.D.Va.1979). Hence, we employ that standard to gauge whether peer review constitutes an “agreement to boycott, coerce, or intimidate,” which could remove it from the shield of the McCarranFerguson Act.11
It is difficult to perceive any “concerted refusal to deal” in the mechanisms of the ACA or VCA. Patients may still freely choose their doctor. Furthermore, the peer review system does not limit the fees of a chiropractor. Indeed, if the Committee finds a charge to be beyond the patient’s insurance, the insurer pays the patient the sum recommended by VCA; the chiroprac*818tor may then seek collection from his insured patient for the amount in excess of the policyholder’s coverage.
If this arrangement induces a patient to employ a chiropractor who charges according to the Committee’s allowances, this is a legitimate option of the patient; it evidences no duress by the member insurers and chiropractic associations. Likewise, the insurance companies do not jointly refuse to do business with chiropractors not belonging to the association. Similarly, no compulsion of any kind requires unwilling chiropractors to surrender to the peer review process.
The judgment denying the defendants’ motions cannot stand. We remand to the District Court with instruction to grant defendants’ motions to dismiss.
