A jury convicted Joseph Kirkham and James Murphy of health care fraud in violation of 18 U.S.C. §§ 1347 and 2. In a prior appeal, we remanded for resentencing in accordance with United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). The district court imposed the same sentences under the now-advisory Guidelines as it had imposed under the pre-Booker mandatory Guidelines.

The defendants jointly appeal their sentences and contend that the loss calculation recounted in the presentence report (PSR) as the basis for their sentences was improperly based on the claims paid by insurers, without proof that every claim *379 was fraudulent. They point to no evidence showing that any particular calculated claim was not in some way fraudulent.

We review their contention clear error. United States v. Messervey, 317 F.3d 457, 464 (5th Cir. 2002). Intended loss is a proper measure of loss in this fraud case. See id. The sentencing court was not required to determine the loss with precision, as long as its estimate was reasonable in light of available information. United States v. Humphrey, 104 F.3d 65, 71 (5th Cir. 1997).

The district court calculated the intended loss based on a “Victim List” for each defendant setting forth the amount of funds the victimized insurance companies disbursed based on the claims submitted by the defendant. Based on the broad extent of the scheme as demonstrated by the trial evidence, it was not clearly erroneous for the district court to conclude “that all of the similar claims under consideration were part and parcel of the same fraudulent scheme.” See United States v. Austin, 432 F.3d 598, 600 n. 2 (5th Cir. 2005). The PSR was sufficiently reliable to establish the amount of loss intended by the defendants’ fraud scheme. See Humphrey, 104 F.3d at 71; § 2F1.1, comment (n.8) (Nov. 2000). Because the defendants submitted no evidence to show that the information in the PSR was materially untrue, the district court was free to adopt the PSR without further explanation. Id.; see United States v. Caldwell, 448 F.3d 287, 289 (5th Cir. 2006) (post-Booker sentence).

The defendants also contend that the district court’s assessment of the reasonableness of their sentences in light of 18 U.S.C. § 3553(a) was perfunctory and inadequate. The defendants were sentenced within properly calculated guideline ranges, and they have failed to rebut the presumption that their sentences were reasonable. See United States v. Alonzo, 435 F.3d 551, 554 (5th Cir. 2006).

The judgment of the district court is

AFFIRMED.
