Kenneth Chipperfield pled guilty to conspiracy to commit mail fraud based on his scheme to fake his own death and have his wife collect his insurance proceeds. After the district court sentenced him to thirty *636 months imprisonment, Chipperfíeld appealed. His attorney has filed a brief pursuant to Anders v. California, 386 U.S. 738, 744, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), stating that there are no meritorious issues for appeal, but addressing the propriety of Chipperfield’s sentence. Chipperfíeld was informed of his right to file a pro se brief but has not done so. Finding no reversible error, we affirm in part and dismiss in part.

Chipperfield’s guilty plea was knowingly and voluntarily entered after a thorough hearing pursuant to Fed. R.Crim.P. 11. The district court properly advised Chipperfíeld as to his rights, the offense charged, and the maximum sentence for the offense. The court also determined that there was an independent factual basis for the plea and that the plea was not coerced or influenced by any promises. See North Carolina v. Alford, 400 U.S. 25, 31, 91 S.Ct. 160, 27 L.Ed.2d 162 (1970); United States v. DeFusco, 949 F.2d 114, 119-20 (4th Cir. 1991).

We find that the district court correctly computed Chipperfield’s offense level and properly refused to decrease his offense level under U.S. Sentencing Guidelines Manual § 2Xl.l(b)(2) (2000), because Chipperfíeld and his co-conspirators had completed all acts they believed necessary for successful completion of the offense. We further find that the district court correctly determined that Chipper-field did not qualify for a departure based on “aberrant behavior.” See USSG § 5K2.20(5).

Chipperfíeld moved for a downward departure based on the impossibility of the scheme. USSG § 2F1.1, comment. (n.ll). The district court denied the motion, finding that the scheme was not impossible and the gravity of the offense was not overstated. Where, as here, the sentencing court was aware of its authority to depart and declined to do so, we lack authority to review its decision. See United States v. Edwards, 188 F.3d 230, 238-39 (4th Cir. 1999); United States v. Bayerle, 898 F.2d 28, 30-31 (4th Cir. 1990). Accordingly, we dismiss this portion of the appeal.

As required by Anders, we have reviewed the entire record and have found no meritorious issues for appeal. We therefore affirm Chipperfield’s conviction and sentence. This court requires that counsel inform his client, in writing, of his right to petition the Supreme Court of the United States for further review. If the client requests that a petition be filed, but counsel believes that such a petition would be frivolous, then counsel may move in this court for leave to withdraw from representation. Counsel’s motion must state that a copy thereof was served on the client. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.
