  OPINION OF THE COURT
  PER CURIAM:
  The District Court dismissed,Count 1 of the plaintiffs’ Complaint as well as its counterclaim and granted the defendants’ motions for summary judgment as to the three other counts of the Complaint.
  On this appeal the plaintiffs challenge only the summary judgments entered. They urge that the District Court applied erroneous legal standards in making its disposition, and further, that existence of genuine issues as to material facts precluded entry of summary judgments on the three concerned counts of the Complaint.
  On review of the record we cannot subscribe to the plaintiffs’ contentions which are exhaustively considered and decided in the District Court’s Opinion, reported at 290 F.Supp. 978 (E.D.Pa. 1968).
  The Order of the District Court, dated and filed October 14, 1968, will be affirmed.
instruction: What follows is an opinion from a United States Court of Appeals.
  Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
  When coding the detailed nature of participants, use your personal knowledge about the participants, if you are completely confident of the accuracy of your knowledge, even if the specific information is not in the opinion. For example, if "IBM" is listed as the appellant it could be classified as "clearly national or international in scope" even if the opinion did not indicate the scope of the business. 
  
  Your task concerns the first listed appellant. The nature of this litigant falls into the category "private business (including criminal enterprises)", specifically "unclear". Your task is to determine what subcategory of business best describes this litigant.
