MEMORANDUM **

Francisco Peraza-Gamboa appeals from the district court’s judgment and challenges the 60-month sentence imposed following his guilty-plea conviction for reentry of a removed alien, in violation of 8 U.S.C. § 1326. We have jurisdiction under 28 U.S.C. § 1291, and we affirm.

Peraza-Gamboa argues that the district court committed procedural error by relying on a clearly erroneous fact that is not pertinent to any of the 18 U.S.C. § 3553(a) sentencing factors. We need not resolve the parties’ dispute over the proper standard of review because Peraza-Gamboa’s contention fails even on de novo review. The district court did not err in considering the timing of Peraza-Gamboa’s guilty plea and the extent of the government’s preparation for trial because its findings regarding those facts were not “clearly erroneous,” and were relevant to consideration of section 3553(a)(6) and his acceptance of responsibility. See United States v. Carty, 520 F.3d 984, 993 (9th Cir. 2008) (en banc).

Peraza-Gamboa also contends that his sentence is substantively unreasonable in *467 light of the alleged procedural errors, the staleness of his nonviolent conviction that led to the 16-level enhancement, and because this was his first immigration offense. The district court did not abuse its discretion in imposing a 60-month sentence. See Gall v. United States, 552 U.S. 38, 51, 128 S.Ct. 586, 169 L.Ed.2d 445 (2007). The below-Guidelines sentence is substantively reasonable in light of the section 3553(a) sentencing factors and the totality of the circumstances, including Peraza-Gamboa’s extensive criminal history. See id.

AFFIRMED.
