    UNITED STATES of America, Plaintiff-Appellee, v. Pamela RICHARDSON, Defendant-Appellant.
    No. 05-50834.
    Summary Calendar.
    United States Court of Appeals, Fifth Circuit.
    Decided March 16, 2006.
    Joseph H. Gay, Jr., Assistant U.S. Attorney, U.S. Attorney’S Office Western District of Texas, San Antonio, TX, for Plaintiff-Appellee.
    J. Michael Cunningham, Midland, TX, for Defendant-Appellant.
    Before BARKSDALE, STEWART, and CLEMENT, Circuit Judges.
   PER CURIAM:

Pamela Richardson appeals: (1) the sentence for her guilty-plea conviction of eight counts of mail fraud, in violation of 18 U.S.C. § 1341; and (2) the denial of her Federal Rule of Criminal Procedure 35(a) motion.

Richardson did not file a notice of appeal from the denial of her Rule 35(a) motion. See Fed. R.App. P. 4(b)(1)(A) (requiring criminal defendant to file notice of appeal within ten days of “the entry of either the judgment or the order being appealed”). Appeals from denials of Rule 35 motions are controlled by the ten-day period dictated by Rule 4(b)(1)(A). United States v. Garcia-Machado, 845 F.2d 492, 493 (5th Cir.1988). A timely notice of appeal is a mandatory prerequisite to our exercise of jurisdiction. United States v. Cooper, 135 F.3d 960, 961 (5th Cir.1998). Because Richardson failed to file a notice of appeal for this denial, we lack jurisdiction to review her challenges to that decision.

Richardson did timely appeal from the final judgment of conviction and sentence. Fed. R.App. P. 4(b)(1)(A). She contends the district court erred in determining the amount of loss attributable to her for sentencing purposes. We review the court’s interpretation and application of the Sentencing Guidelines de novo; its factual findings, for clear error. E.g., United States v. Olis, 429 F.3d 540, 545 (5th Cir. 2005). A district court’s amount-of-loss determination is not clearly erroneous if it is plausible in the light of the record as a whole. E.g., United States v. Oates, 122 F.3d 222, 225 (5th Cir.1997). Along this line, the loss calculation was not clearly erroneous. See id.

DISMISSED in PART; AFFIRMED in PART. 
      
       Pursuant to 5th Cir. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5th Cir. R. 47.5.4.
