claim: (1) the district court erred in admitting a Dun & Bradstreet report and the banking records of Southwestern Manufacturing & Equipment Co.; (2) the conduct of the trial judge denied them a fair trial; (3) the district court erred in failing to give certain requested jury instructions; and (4) the evidence was insufficient to support their convictions. Finding no merit in these contentions, we affirm.
I. Facts
Defendants were engaged in a scheme to defraud companies involved in financing the purchase of heavy machinery. These companies lease heavy machinery to companies that cannot afford to purchase it outright or through bank loans. In a typical transaction, the leasing company, upon determining that a lessee is creditworthy, purchases from a vendor machinery needed by the lessee. The vendor then sends the equipment directly to the lessee, who notifies the leasing company of the machinery’s arrival and condition. At that point, the leasing company pays the vendor and begins to receive monthly lease payments from the lessee.
Defendants Glen Adkins, Tom Adkins and Walter Cannon owned vendor companies that never actually had any machinery. Cannon, and later defendant Ron Hawkins, owned Powerguard of Texas, Inc., a lessee company that would falsely certify to victim leasing companies that it had received equipment from the phony vendors. After the victims paid Cannon and the Adkins brothers for the machinery, Powerguard defaulted on the lease payments. When the leasing companies attempted to repossess the equipment, they discovered that it had never existed or was worthless.
II. Admissibility of Dun & Bradstreet Report
Defendants contest the admission of a Dun & Bradstreet report that described the business of Southwestern Manufacturing & Equipment Co., a spurious lessee company owned by Tom and Glen Adkins. The report listed the names of Southwestern’s corporate officers, the number of its employees, the amount of office space and the credit history of the company. Through other testimony, the government demonstrated that most of the information was false. Defendants argue that the report was hearsay and should not have been admitted.
Hearsay is a statement offered in evidence to prove the truth of the matter asserted. Fed.R.Evid. 801. The Dun & Bradstreet report was not offered, however, to prove the truth of the matter asserted, that Southwestern’s facilities and employees were as reported. Rather, the government offered the report to establish a foundation for later showing, through other admissible evidence, that it was false. United States v. McDonnel, 550 F.2d 1010, 1012 (5th Cir.), cert, denied, 434 U.S. 835, 98 S.Ct. 123, 54 L.Ed.2d 96 (1977). When statements are introduced to prove the falsity of the matter asserted, they are not inadmissible as hearsay. Id. Cf. Anderson v. United States, 417 U.S. 211, 220, 94 S.Ct. 2253, 2260, 41 L.Ed.2d 20 (1974); United States v. Hershenow, 680 F.2d 847, 861 n. 12 (1st Cir.1982); United States v. Weaver, 565 F.2d 129, 136 (8th Cir.1977), cert, denied, 434 U.S. 1074, 98 S.Ct. 1263, 55 L.Ed.2d 780 (1978). Thus, the Dun & Bradstreet report is not hearsay and was properly admitted.
III. Admission of Southwestern’s Banking Records
Defendants next assert that the trial court should, as a sanction against the government for violating discovery rules, have refused to admit the banking records of Southwestern. Defendants have not shown, however, that the government violated any discovery rule.
Defendants admit that, prior to trial, the prosecutor informed them that he had the bank records and that they were available for inspection. The prosecutor also told defendants that as of that time he did not intend to offer the records in evidence.
On the third day of trial, the government informed defense counsel that it had reconsidered and would introduce the records. The prosecutor then provided defense coun
