AMENDED SUMMARY ORDER

L.M. appeals from a judgement of the United States District Court for the Eastern District of New York imposing an incarceratory sentence of one year and one day. We assume the parties’ familiarity with the underlying facts, the procedural history, and the issues presented for review.

BACKGROUND

The facts here are undisputed. L.M. began distributing marijuana in the 1980s. He eventually came to the attention of law enforcement, who executed a search warrant on his home and confiscated ten pounds of marijuana.

That arrest was the genesis of a long and fruitful cooperation with authorities. L.M. provided information that led to the arrests and successful prosecutions of a number of large-scale international drug dealers. In addition, he recorded his conversations with various members of drug distribution organizations and made himself available as a trial witness. Because of his extensive assistance to law enforcement, L.M. received a number of credible threats of violence; to ensure his safety, authorities installed a panic button in his home. As the government conceded at oral argument, L.M. “uniquely earned” the government’s motion pursuant to Section 5K1.1 of the United States Sentencing Guidelines urging a downward departure.

Letters submitted on L.M.’s behalf, if credited, show that his arrest also marked the beginning of an admirable personal transformation. In the nearly seventeen years that have elapsed since his arrest, he has built both a family and a business. His wife of twenty-seven years describes him as a devoted husband and a loving father to their four children, and a colleague reports that L.M. is a widely-respected and fair boss who dramatically reduced his own salary in the economic downturn to avoid laying off employees. Further, letters from L.M.’s father and sister describe L.M. as a compassionate son and brother, a man who cared for them through their long illnesses.

L.M. pleaded guilty to one count of conspiracy to distribute marijuana and one count of filing a false tax return. The suggested Guidelines range was forty-six to fifty-seven months of incarceration. With little explanation, the district court imposed an incarceratory sentence of one year and one day. Two weeks later, L.M. filed a motion for reconsideration, which the district court denied. L.M. now appeals the district court’s sentence as procedurally and substantively unreasonable.

DISCUSSION

We review the sentence imposed by the district court to ascertain whether it is reasonable. Gall v. United States, 552 U.S. 38, 46-47, 128 S.Ct. 586, 169 L.Ed.2d 445 (2007); United States v. Cavera, 550 F.3d 180, 187-88 (2d Cir. 2008) (en banc). Reasonableness review is “akin to review for abuse of discretion.” United States v. Fernandez, 448 F.3d 19, 27 (2d Cir. 2006). Our review for reasonableness has both *27 procedural and substantive components. See, e.g., Cavern, 550 F.3d at 189.

L.M. first contends that his sentence is proeedurally unreasonable for two principal reasons: (1) the district court did not properly consider the factors set forth in 18 U.S.C. § 3553(a) in fashioning its sentence; and (2) the district court did not adequately explain its sentence as mandated by 18 U.S.C. § 3553(c). We address only the second argument here. A sentence is proeedurally unreasonable if, among other things, the lower court fails to adequately explain the basis for the sentence it imposed. See, e.g., United States v. Johnson, 567 F.3d 40, 51 (2d Cir. 2009). Requiring the district court to articulate the reasons for its sentence (1) “helps to ensure that [it] actually consider[s] the statutory factors and reach[es] [a] reasoned deeision[]”; (2) “promote[s] the perception of fair sentencing”; and, most importantly, (3) assures “meaningful appellate review.” Cavern, 550 F.3d at 193 (internal quotation marks omitted).

The district court did not adequately explain its sentence. Particularly troubling, given the passage of fifteen years between L.M.’s arrest and sentencing, is the court’s failure to discuss the extent to which it considered evidence of L.M.’s rehabilitation in fashioning its sentence. See United States v. Hernandez, 604 F.3d 48, 55 n. 4 (2d Cir. 2010). Of course, the district court simply might not have credited L.M.’s claims of rehabilitation, see United States v. Preacely, 628 F.3d 72, 85 (2d Cir. 2010) (Lynch, J., concurring), or it might have believed the seriousness of L.M.’s crime outweighed even the most compelling evidence of rehabilitation. However, given the paucity of the district court’s explanation, we cannot be sure that the district court arrived at a reasoned decision over which we can meaningfully exercise appellate review. For this reason, we vacate the sentence imposed by the district court as proeedurally unreasonable.

Because we determine that the sentence imposed on L.M. is proeedurally unreasonable, we do not address the thorny issue of whether, under the unique circumstances of this case, an incareeratory sentence of one year and one day is substantively unreasonable. On remand, the district court shall have plenary authority to impose a sentence consistent with law. We further elect to remand in accordance with the procedures set forth in United States v. Jacobson, 15 F.3d 19, 22 (2d Cir. 1994). Either party may restore jurisdiction to this Court to consider whatever arguments remain or arise relating to L.M.’s resen-tencing by sending a letter to the Clerk of the Court within 14 days of the district court’s decision. Any such proceedings will be assigned to this panel.

After a thorough and searching review of the record, we find L.M.’s remaining arguments to be meritless.

For the foregoing reasons, the judgment of the district court imposing an incarcera-tory sentence of one year and one day is hereby VACATED. We REMAND for resentencing proceedings consistent with this order. The mandate shall issue forthwith.
