Gerald Sherman appeals a wire, mail, and securities fraud conviction, as well as the sentence imposed by the district court. We have jurisdiction pursuant to 28 U.S.C. *721§ 1291 and 18 U.S.C. § 8742. We affirm the conviction, vacate the sentence, and remand for resentencing.

Sherman raises two issues on appeal: (1) whether the district court abused its discretion in permitting expert testimony concerning the characteristics of investment fraud schemes and (2) whether the district court committed procedural error by failing to adequately explain its use of the two-level sentencing enhancement for obstruction of justice. We address each issue in turn.

We review for abuse of discretion a district court’s decision to admit expert opinion testimony. United States v. Gonzales, 307 F.3d 906, 909 (9th Cir. 2002). A district court’s evidentiary ruling will be reversed only if “ ‘manifestly erroneous.”” Id. (quoting United States v. Hankey, 203 F.3d 1160, 1167 (9th Cir. 2000)).

The district court did not abuse its discretion in admitting expert testimony regarding the structure of fraudulent financial schemes. See United States v. Andersson, 813 F.2d 1450, 1458 (9th Cir. 1987) (government experts “‘may testify concerning the techniques and methods used by criminals.’ ” (quoting United States v. Rogers, 769 F.2d 1418, 1425 (9th Cir. 1985))). The evidence here pertained to the nature of the act, rather than the disposition of the actor, and so is distinguishable from the “character” or “profiling” cases relied upon by Appellant.

In addition, contrary to Appellant’s arguments, the expert’s testimony was relevant as well as probative of the fraudulent nature of the financial transactions at issue. Moreover, the testimony was limited by the district court’s ruling on Sherman’s motion in limine. Accordingly, we conclude that the testimony of Appellee’s anti-fraud financial expert was properly admitted, and we affirm Sherman’s conviction.

However, the district court failed to adequately explain its use of the two-level sentencing enhancement for obstruction of justice.1 In United States v. Carty, 520 F.3d 984 (9th Cir. 2008) (en banc), cert. denied, — U.S. -, 128 S.Ct. 2491, 171 L.Ed.2d 780 (2008) we held that such a failure is a “procedural error” within the meaning of the recent Supreme Court decision of Gall v. United States, — U.S. -, 128 S.Ct. 586, 597, 169 L.Ed.2d 445 (2007).

Sherman objected to the Presentence Report (“PSR”) and so the court had to make specific findings.2 Instead, the court adopted the PSR without comment even *722though the PSR also did not sufficiently express facts to support the obstruction enhancement. Accordingly, remand for resentencing is required for this non-harmless procedural error. See United States v. Grissom, 525 F.3d 691, 695-97 & n. 2 (9th Cir. 2008).

Sherman’s conviction is AFFIRMED, his sentence is VACATED, and we REMAND for resentencing.
