Mary Ellen Pallo appeals from the district court’s order revoking her supervised release and sentencing her to four months imprisonment. On appeal, she contends that the court abused its discretion when it revoked her release. We affirm.

We review the district court’s decision to revoke a defendant’s supervised release for an abuse of discretion. United States v. Copley, 978 F.2d 829, 831 (4th Cir. 1992). The district court need only find a violation of a condition of supervised release by a preponderance of the evidence. 18 U.S.C.A. § 3583(e)(3) (West Supp. 2004). We review factual determinations informing the conclusion that a violation occurred for clear error. United States v. Carothers, 337 F.3d 1017, 1019 (8th Cir. 2003); United States v. Whalen, 82 F.3d 528, 532 (1st Cir. 1996) (finding district court’s credibility determinations concerning evidence presented at a supervised release revocation hearing not reviewable on appeal).

Here, the court found Pallo’s testimony that her violations of supervised release were caused by miscommunications to be not credible. In addition, although Pallo provided excuses for failing to meet her financial.and reporting requirements, it is undisputed that she did not comply with *295 the conditions of her supervised release. Thus, we find that a preponderance of the evidence supported the district court’s findings. The district court was, therefore, statutorily authorized to revoke supervised release and impose a prison term. 18 U.S.C.A. § 3583(e)(3).

Accordingly, we affirm the district court’s judgment. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.

AFFIRMED
