Evyan Wallace appeals the sentence he received upon revocation of his term of supervised release. He argues that the sentence is unreasonable because it exceeds the sentencing range recommended by the relevant policy statements in the Sentencing Guidelines and because the district court failed to specify its reasons for the sentence. The Government moves to dismiss the appeal or for summary affirmance on the basis that we lack jurisdiction to consider it under 18 U.S.C. § 3742(a)(4). Wallace has served the entirety of his sentence and was released from prison on February 6, 2007. Because the issue raised in Wallace’s appeal is moot, the appeal is DISMISSED. See Spencer v. Kemna, 523 U.S. 1, 7, 15, 118 S.Ct. 978, 140 L.Ed.2d 43 (1998). The Government’s motions are DENIED.
