opinion: PER CURIAM.
  Plaintiff bank in this action sought recoupment of money in the sum of $5,054 which was set off from the funds of plaintiff bank on the instruction of defendants while the funds were in the hands of the Federal Reserve Bank of Atlanta, Georgia. By this means the United States Government made itself whole for the loss to it resulting from plaintiff bank’s having cashed six stolen Series E United States Savings Bonds for a Mr. Monroe, a professional forger who presented himself as a Mr. Kreiss, the owner of the bonds, having in his possession a forged driver’s license, Social Security card, and credit cards in the name of said Kreiss.
  The facts before the District Judge indicated that Mr. Monroe was a complete stranger to the bank personnel, that the bonds had a New Jersey mailing address, and that he presented a driver’s license with a Pennsylvania address. The bank officers did not seek to corroborate Mr. Monroe’s statements as to his intention to purchase a coin collection in Elizabethton, Tennessee, nor did the bank officers seek corroboration of his identification documents.
  The District Judge found that the bank personnel “simply did not' exert due care in cashing these forged bonds.”
  31 U.S.C. § 757c(i) (1970) authorizes the Treasurer of the United States to issue regulations pertaining to the fault or negligence of paying agents such as the plaintiff bank in the cashing of Savings Bonds. In a Treasury Department statement dated December 19, 1947, concerning identification of persons seeking to cash such bonds, and pertaining directly to the employment of motor vehicle operator’s licenses for such purposes, the instruction statement said in part, “In any case of doubt, other acceptable documents should be required for corroborative purposes.”
  Under the total circumstances of this case, as set out above, and as set out more fully in the District Judge’s opinion filed June 15, 1972, we conclude that the District Judge’s finding of lack of due care is not clearly erroneous. Fed.R.Civ.P. 52(a).
  The judgment of the District Court is 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 "financial institution". Your task is to determine what subcategory of business best describes this litigant.
