William Henry Johnson appeals the district court’s order denying the motion filed pursuant to 18 U.S.C.A. § 3582(c) (West 2000 & Supp. 2008), to reduce his sentence. Because Johnson has completed his term of imprisonment, his appeal may well be moot. See United States v. Guess, 541 F.Supp.2d 399, 401-05 (D.Me. 2008). In any event, the district court did not abuse its discretion in denying Johnson’s § 3582(c) motion. Accordingly, we affirm. 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.
