MEMORANDUM **

Kato Amosa Iosua appeals pro se from the district court’s order denying his motion for a sentence reduction under 18 U.S.C. § 3582(c)(2). We have jurisdiction under 28 U.S.C. § 1291. We review de novo whether a district court has authority to modify a sentence under section 3582(c)(2), see United States v. Leniear, 574 F.3d 668, 672 (9th Cir. 2009), and we affirm.

Iosua contends that he is entitled to a sentence reduction under Amendment 782 to the Sentencing Guidelines. The district court correctly concluded that Iosua is ineligible for a sentence reduction because his sentence is already below the minimum of the amended Guidelines range. See U.S.S.G. § lB1.10(b)(2)(A) (“[T]he court shall not reduce the defendant’s term of imprisonment under 18 U.S.C. § 3582(c)(2) and this policy statement to a term that is less than the minimum of the amended guideline range.”). Contrary to Iosua’s contention, section IB 1.10(b) does not im-permissibly restrict the discretion of the district court to reduce a sentence in a section 3582(c)(2) proceeding. See United States v. Davis, 739 F.3d 1222, 1225-26 (9th Cir. 2014).

We do not consider matters not specifically and distinctly raised and argued in the opening brief. See Padgett v. Wright, 587 F.3d 983, 985 n.2 (9th Cir. 2009).

AFFIRMED.
