*655 MEMORANDUM **

Howard Wesley Cotterman appeals from the district court’s judgment and challenges the 35-year sentence imposed following his bench-trial convictions for two counts of production of child pornography, in violation of 18 U.S.C. §§ 2251(a), (e), and 2256(2); transportation and shipping of child pornography, in violation of 18 U.S.C. §§ 2252(a)(1), (b)(1), and 2256(2); possession of child pornography, in violation of 18 U.S.C. §§ 2252(a)(4)(B), (b)(2), and ,2256(2); and importation of obscene material, in violation of 18 U.S.C. § 1462(a). We have jurisdiction under 28 U.S.C. § 1291, and we affirm.

Cotterman first argues that the district court procedurally erred by failing to consider the 18 U.S.C. § 3553(a) sentencing factors and by failing to adequately explain its sentencing decision. We review for plain error, see United States v. Valencia-Barragan, 608 F.3d 1103, 1108 (9th Cir. 2010), and find none. A court is not required to discuss each individual sentencing factor, and we assume that the district court knew the law and understood its obligation to consider the factors under 18 U.S.C. § 3553(a). See United States v. Carty, 520 F.3d 984, 992 (9th Cir. 2008) (en banc). Moreover, the reasons for imposing the sentence are readily apparent from the record. See id.

Next, Cotterman asserts that his sentence is substantively, unreasonable. We review a claim that a sentence is substantively unreasonable for abuse of discretion. See Gall v. United States, 552 U.S. 38, 51, 128 S.Ct. 586, 169 L.Ed.2d 445 (2007). In light of the troubling nature of the offense, as well as Cotterman’s criminal history, the court did not abuse its discretion. See id.

AFFIRMED.
