Following a jury trial, Mr. Ottersburg was convicted of two eounts of executing a scheme to defraud by transporting property in interstate commerce, 18 U.S.C. § 2314, and one count of defrauding a financial institution, 18 U.S.C. § 1005. His appeal asserts that the district court committed reversible error when it failed to dismiss two alternate jurors and permitted them to deliberate' with the jury. For the reasons set forth in the following opinion, we reverse Mr. Otters-burg’s convictions and remand for proceedings consistent with this opinion.
*138 I
BACKGROUND
Mr. Ottersburg owned and operated a Ford dealership in Staunton, Illinois. Counts I and II of the indictment against him charged that he leased cars from Ford at out-of-state auctions, transported them back to Illinois, and sold them as if he were the proper owner of the cars. The third count of the indictment alleged that Mr. Ottersburg defrauded the First National Bank of Staun-ton by receiving loans from the bank, using cars in his inventory as collateral, and then failing to pay off the bank when he sold the cars. The fourth count of the indictment charged that Mr. Ottersburg secured a loan from the bank by pledging, as collateral, a vehicle of which he had only temporary possession.
Following closing arguments, the judge instructed the twelve-person jury and the alternates. When the jury was sent to retire, the court did not dismiss the two alternates, but rather permitted them to retire with the jury to deliberate. The deliberations lasted over nine hours. When the jury returned with its verdict, it became apparent that the alternates had not signed the verdict forms. The court noted that although “the two alternates went back with the jury and deliberated along with the rest of the members of this jury,” only the twelve jurors had signed the verdict forms. Tr. 665. It then instructed the fourteen to return to the jury room so that the alternates could also sign the verdict forms. The jury left the courtroom and returned momentarily with fourteen signatures on the verdict forms. When asked, the jury’s foreman confirmed that the verdicts were the verdicts of the entire jury, “including the alternates.” Tr. 667. The alternates were polled, along with the jury, and they acknowledged the verdict as their own. Mr. Ottersburg never objected to the alternates’ participation during the jury’s deliberations.
The jury and the alternates acquitted Mr. Ottersburg of Count III, but convicted him of the remaining charges. He was sentenced to thirty months’ imprisonment.

DISCUSSION
Mr. Ottersburg asserts that the district court, by permitting the two alternate jurors to retire along with the jury, violated Rule 24(c) of the Federal Rules of Criminal Procedure. That rule provides, in part, that “[a]n alternate juror who does not replace a regular juror shall be discharged after the jury retires to consider its verdict.” Fed. R.Crim.P. 24(c) (emphasis added).
Our consideration of this question is controlled by the Supreme Court’s analysis in
United States v. Olano,
Under the Court’s analysis, the first prerequisite under Rule 52(b) is that there must be an “error.” The Court pointed out that “deviation from a legal rule is ‘error’ unless the rule has been waived.”
Olano,
If an error exists, the next question is whether that error is “plain,” meaning that the error is “clear under current law.” Id. In this case, the failure to dismiss the two alternate jurors was a clear violation of the dictates of Rule 24(c).
The third limitation of Rule 52(b) is that the plain error must “affect substantial rights.” In most cases, as
Olano
makes clear, this requirement means that the error must result in prejudice to the defendant. The defendant bears the burden of persuasion on this issue.
Id.
If all three of the requirements of Rule 52(b) are satisfied, then the court of appeals has the authority to correct the error, but need not exercise that authority. Rather, the decision to correct “plain error” lies within the appellate court’s discretion.
2
Olano
holds that the exercise of that discretion is governed by the standard set forth in
United States v. Atkinson,
In
Olano,
the court wrote, “[t]he presence of alternate jurors during jury deliberations is not the kind of error that ‘affect[s] substantial rights’ independent of its prejudicial impact.”
Id.
Therefore,
Olano
requires that we assess whether the presence of the two alternate jurors throughout the deliberations of the jury prejudiced the defendant either “specifically or presumptively.”
Id.
Because this case, like
Olano,
is governed by the plain error standard, it is the obligation of the defendant to demonstrate that the deviation from the requirements of Rule 24(c) was prejudicial.
Id.
If, as the Supreme Court directed in Ola-no, we are to presume that the jurors and the alternates followed the instructions of the court, we must conclude that the jurors and the alternates deliberated as a body and, as the court required of them, delivered a unanimous verdict. It is clear, then, that the twelve jurors permitted to decide the fate of Mr. Ottersburg had substantive communications during their deliberations with persons, the alternates, who were not supposed to participate in those deliberations. To reach a contrary conclusion, we would be required to presume that the alternates did not follow the court’s instructions and, for nine and a half hours of deliberations, sat mute in the jury room. 3
Although Olano indicates that the substantive participation of the alternates, once established, is sufficient to establish prejudice, we hasten to add that, in this case, other factors also compel the conclusion that the jury’s verdict cannot be relied upon. The length of the jury’s deliberations makes clear that this case was not an easy one for those called to serve as finders of fact. The jury did not find the defendant guilty of all charges, and at least one of the charges upon which he was convicted presented a relatively close issue of proof.
As we have noted earlier, Rule 52(b) is permissive, not mandatory.
Olano,
Conclusion
The judgment of the district court is reversed. The case is remanded for proceedings consistent with this opinion.
