Roy Arredondo, Jr., appeals the sentence imposed following his guilty-plea conviction for conspiracy to distribute and possess with intent to distribute five kilograms or more of cocaine, 100 kilograms or more of marijuana, and 500 grams or more of methamphetamine. He argues that the district court erred by imposing a four-level enhancement pursuant to U.S.S.G. § 3Bl.l(a) for his being an organizer or leader of criminal activity involving five or more participants.

We review a district court’s interpretation and application of the Sentencing Guidelines de novo and its factual findings for clear error. United States v. Villanueva, 408 F.3d 193, 202-03 & n. 9 (5th Cir.), cert. denied, — U.S.-, 126 S.Ct. 268, 163 L.Ed.2d 241 (2005). The district court’s application of a § 3B1.1 adjustment is a factual matter that is reviewed for clear error. United States v. Dadi, 235 F.3d 945, 951 (5th Cir. 2000).

While the testimony at sentencing was based on information received from unidentified individuals and some of Arredondo’s co-conspirators, hearsay evidence may be considered at sentencing if it has suffieient indicia of reliability, and Arredondo has not shown that the testimony did not have sufficient indicia of reliability. See United States v. Gaytan, 74 F.3d 545, 558 (5th Cir. 1996). Given the testimony at sentencing and “the extreme deference of the ‘clear error’ standard,” United States v. Lowder, 148 F.3d 548, 554 (5th Cir. 1998), the district court’s application of the four-level enhancement for Arredondo’s being an organizer or leader of the criminal activity was not clearly erroneous.

AFFIRMED.
