Affirmed by unpublished PER CURIAM opinion.

Unpublished opinions are not binding precedent in this circuit.

Bricelyn Marcel Russell seeks to appeal the district court’s order denying his motion for reduction of sentence under 18 U.S.C. § 3582 (2006). Russell was originally sentenced at the bottom of his guideline range to 360 months in prison. The district court subsequently granted the Government’s motions under Fed. R.Crim.P. 35(b) and reduced Russell’s sen *347 tence to 180 months. In denying Russell’s § 3582(c)(2) motion, the district court determined that his amended guideline range under the crack cocaine amendments was 292 to 365 months’ imprisonment; noted the court had already reduced his sentence to 180 months; and denied his motion for a further reduction.

On appeal, Russell challenges the district court’s reasoning for denying his motion. Because we conclude that the district court lacked authority under 18 U.S.C. § 3582(c)(2) to reduce Russell’s term of imprisonment to a term that was less than the bottom of the amended guideline range, we affirm. See United States v. Dunphy, 551 F.3d 247, 250, 252 (4th Cir. 2009). 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.
