OPINION
Following a jury trial, Shirley Mackey was convicted of sixty-two counts of wire fraud, in violation of 18 U.S.C. §§ 1343 & 2, and one count of conspiracy, in violation of 18 U.S.C. § 371. Mackey appeals these convictions, arguing that she was denied a fair trial when the district court allowed two jurors to remain after jury deliberations were suspended for the evening to perform research on the evidence in order to summarize it for all of the jurors. Mackey also contends that the district court clearly erred when it found that she occupied a position of trust as provided *472 for in the Sentencing Guidelines. Finding no merit in her arguments, we affirm.
I.
On May 30, 1995, the director of security operations for Woodward and Lothrop Department Stores discovered that fraudulent return of merchandise credits totaling approximately $40,000 had been issued to credit cards during the period from December 1994 through May 1995. His investigation led him to believe that the perpetrators of the fraud were Shirley Mackey and Paula Williams, two employees from the Sales Audit Department of Woodward and Lothrop’s corporate headquarters in Alexandria, Virginia. Mackey’s computer authorization code had been used on all but one of the fraudulent transactions.
On June 1, 1995, Mackey was interviewed by two Secret Service agents, at which time she admitted that, during her employment as a group leader in the Sales Audit Department, she had entered unauthorized credits for non-existent returns of merchandise into the Woodward and Lothrop computer on at least five occasions for her daughter, and for Williams’s mother and brother. Mackey also admitted to giving her computer authorization number to Williams so that Williams could execute fraudulent credits on her own computer.
Williams pled guilty in August 1995, and subsequently testified at Mackey’s trial that Mackey had offered to enter credits for Williams and her friends and relatives; that Mackey did enter such credits; and that Mackey later gave Williams the confidential computer access code that Williams used to effect other fraudulent credits. Thirteen other witnesses who had benefitted from the scheme testified at the trial to the fraudulent returned merchandise credits they had received from Mackey. In addition, hundreds of pages of documentation, including records of over 130 credit card charge transactions and of the subsequent reversals of those charges, were admitted into evidence.
In his final instructions to the jury, the trial judge stated:
Your verdict must represent the collective judgment of each juror. In order to return a verdict, it is necessary that each juror agree to it. Your verdict, in other words, must be unanimous.... Each of you must decide the case for himself and herself, but do so only after an impartial consideration of the evidence in the case with your fellow jurors____ Your verdict must be based solely upon the evidence received in this case. Nothing you may have seen or heard or read outside the court may be considered.
Just prior to excusing the jury to deliberate, the trial judge informed the jury that they could take a lunch break, but cautioned: “I just ask that when you go on your lunch break, if two or three of you go off together, that you not discuss the case; you wait until all twelve of you are back in the jury room, so that everyone receives the benefit of your views.” The jury was excused to deliberate at approximately 11:50 a.m. on September 28, 1995.
At about 6:30 p.m., the jury sent a note to the trial judge asking the following question: “Can some jurors, but not all, stay and perform research activities on the evidence so as to present summary data to all jurors tomorrow?” Over defense counsel’s objection, the trial judge decided to allow some jurors to stay. He stated to counsel that he would “let them do the research, as long as they understand it has to be a unanimous decision and they will have [to] satisfy themselves the research is accurate.” The trial judge then instructed the jury as follows: “Several of you want to stay and do some research; is that right? It’s okay, as long as your decision is unanimous and all of you are satisfied the research is accurate, the people doing the research can furnish back-up data.”
The jury was then excused for the evening. The next day, the jury began deliberating at 9:00 a.m. Approximately two hours later, they returned a verdict of guilty on sixty-three counts, and of not guilty on the remaining sixty-three counts.
At sentencing, the district court imposed a two-point enhancement for abuse of a position of trust pursuant to U.S.S.G. § 3B1.3, and sentenced Mackey to a term of imprison *473 ment of 30 months and to three years of supervised release.
II.
Mackey contends that district court erred in allowing some jurors to remain to perform research on the evidence after jury deliberations ended for the evening. We shall assume for purposes of discussion that this contention is correct. Mackey further asserts that this error constituted a structural error that requires automatic reversal of her conviction. We disagree with Mackey’s claim of structural error, and find that the actions of the trial court are subject to harmless error analysis.
A.
“[T]he Constitution entitles a criminal defendant to a fair trial, not a perfect one.”
Delaware v. Van Arsdall,
The Supreme Court has recognized that most errors can be harmless,
Arizona v. Fulminante,
In
Sherman v. Smith,
[cjorreetly applied, harmless error and structural error analyses produce identical results: unfair convictions are reversed while fair convictions are affirmed. Expanding the list of structural errors, however, is not mere legal abstraction. It can also be a dangerous endeavor. There is always the risk that a sometimes-harmless error will be classified as structural, thus resulting in the reversal of criminal convictions obtained pursuant to a fair trial. Given this risk, judges should be wary of prescribing new errors requiring automatic reversal. Indeed, before a court adds a new error to the list of structural errors (and thereby requires the reversal of every criminal conviction in which the error occurs), the court must be certain that the error’s presence would render every such trial unfair.
Like the error at issue in
Sherman,
the error at issue in the present case — allowing some jurors to stay to perform research on the evidence in order to summarize it for all of the other jurors who had gone home for the evening — obviously can occur in a discrete moment of an otherwise fair trial. Moreover, this error appears to be less severe than other instructional errors that the Supreme Court has subjected to harmless error analysis. For example, in
Rose v. Clark,
B.
In
Chapman v. California,
Applying these principles to the present case, we find that the trial court’s error was harmless. First, we note that the evidence summarized by the jurors who stayed was properly admitted during the trial. Thus, this ease is not one involving consideration of extraneous evidence.
Second, the district court’s instructions clearly directed the jury not to deliberate unless all jurors were present. During its general instructions, the trial court informed the jury that each juror must decide the case for himself or herself; it further instructed the jurors not to discuss the case in groups of two or three during their lunch break, but rather to wait until all twelve jurors were together so that all jurors would receive the benefit of each juror’s views. In addition, after receiving the jury note at issue here, the judge advised the jury that its decision would have to be unanimous and that all jurors would have to satisfy themselves that the summaries were accurate. Taken together, these instructions provided adequate guidance for the two remaining jurors to know that they should not deliberate on the merits of the case. Indeed, there is no evidence that the remaining jurors failed to comply with these instructions. We therefore have no valid basis for concluding that defendant’s right to a jury trial was impaired.
Third, the state offered ample evidence at trial to support the jury’s conclusion that Mackey had committed conspiracy and multiple acts of wire fraud. Mackey confessed during an interview conducted by Secret Service agents that she entered unauthorized credits on at least five occasions, and that she gave her computer authorization number to Williams, her co-conspirator. Williams’s *475 testimony at trial — that Mackey entered credits for Williams and her friends and relatives, and gave Williams the confidential computer access code — was consistent with these admissions. At trial, Mackey further-admitted that she conducted fraudulent returned merchandise credits for her friend Bonnie Stokely. These fraudulent credits were confirmed by Stokely, who also testified at Mackey’s trial. In all, the government produced thirteen witnesses who testified that they received fraudulent returned merchandise credits from Mackey. This powerful testimonial evidence was buttressed by the admission of numerous documents that chronicled the relevant credit card charges and the subsequent reversals of those charges.
In light of the whole record in this ease, including the extensive evidence presented at trial, we find that any error by the trial judge was harmless beyond a reasonable doubt.
III.
Mackey also argues that she did not occupy a position of trust warranting a two-level enhancement under section 3B1.3 of the Sentencing Guidelines, “Abuse of Position of Trust or Use of Special Skill,” which provides, in pertinent part, that “[i]f the defendant abused a position of public or private trust, or used a special skill, in a manner that significantly facilitated the commission or concealment of the offense, increase by 2 levels.” U.S.S.G. § 3B1.3.
While the Guidelines do not define “position of trust,” the commentary to section 3B1.3 explains that
“[pjublie or private trust” refers to a position of public or private trust characterized by professional or managerial discretion. ... For this enhancement to apply, the position of trust must have contributed in some significant way to facilitating the commission or concealment of the offense____ This adjustment, for example, would apply in the case of an embezzlement of a client’s funds by an attorney serving as a guardian, a bank executive’s fraudulent loan scheme, or the criminal sexual abuse of a patient by a physician under the guise of an examination. This adjustment would not apply in the ease of an embezzlement or theft by an ordinary bank teller or hotel clerk____
U.S.S.G. § 3B1.3, comment note 1. We have enumerated several factors that must be considered in determining whether a defendant held a position of trust:
First, courts ask whether the defendant had special duties or “special access to information not available to other employees.” Second, the defendant’s level of supervision or “degree of managerial discretion” is relevant. Bank tellers who embezzle from their employers provide an example of a situation where there is little trust to abuse because the employees are closely supervised, and it is expected that wrongs they commit will be readily detected. Third, the analysis also entails an examination of “the acts committed to determine whether this defendant is ‘more culpable’ than others” who hold similar positions and who may commit crimes.
United States v. Gordon,
The district court found that Mackey occupied a position of trust. The court focused on Mackey’s possession of the computer access code, determining that this facilitated concealment of the fraudulent conduct and endowed her with information that was unavailable to others. Thus, the court concluded that Mackey did not fit within the “bank teller” exception. The district court’s ruling in this regard “is a factual determination reviewable for clear error.”
Glymph,
Mackey relies on
Helton,
Helton is easily distinguishable from the present case. Here, Mackey had been a group leader in the Sales Audit Department of Woodward and Lothrop for ten years. She was one of two group leaders in this department, and was responsible for supervising other auditors. In this capacity, she was authorized to possess and utilize a computer authorization code, which gave her special access to the company’s data base, and enabled her to commit the fraud and conceal it from detection. The employees she supervised, including Williams, did not have access to this code. Under these circumstances, the district court’s determination that Mackey occupied a position of trust was not clearly erroneous.
AFFIRMED.
