challenges several evidentiary rulings, the denial of his motion for judgment of
acquittal, and several sentencing decisions. We have jurisdiction under 28 U.S.C.
§ 1291, and we affirm. Because the parties are familiar with the facts of this case, we
do not recount them here except as necessary to provide context for our decisions.
1. The district court did not err in overruling Patterson’s objections to, and his
motion to strike, the testimony of IRS revenue agent Debra Steele (“Steele”). Steele’s
testimony about her bank deposits analysis (“BDA”) was not inadmissible hearsay,
irrelevant, or unfairly prejudicial, and it did not violate Patterson’s Sixth Amendment
right of confrontation. Even if we assume without deciding that the district court
plainly erred in failing to exclude Steele’s testimony regarding Patterson’s tax returns
as improper expert testimony or lay opinion testimony, that error did not affect
Patterson’s substantial rights, so he is not entitled to relief. See United States v.
Gomez-Norena, 908 F.2d 497, 500 (9th Cir. 1990) (holding that unpreserved
evidentiary objections are reviewed for plain error); see also United States v. Olano,
507 U.S. 725, 734 (1993) (holding there is no plain error where substantial rights are
not affected).
2. The district court did not abuse its discretion in allowing the government to
-2-
use Exhibits 395 and 397 as demonstrative aids1 after they had been withdrawn from
evidence. See Lies v. Farrell Lines, Inc., 641 F.2d 765, 773 n. 9 (9th Cir. 1981)
(citation omitted) (“The admissibility of demonstrative evidence in particular is
largely within the discretion of the trial judge.”). Although the district court did not
explicitly cite Rule 403 or recite the elements of Rule 403’s balancing test when
considering this issue, its explanation indicates that it conducted a proper Rule 403
analysis to determine whether the exhibits should have been allowed as demonstrative
aids.
3. The district court did not err in admitting Exhibits 81, 440, and 413.
Exhibits 81 and 440 were admitted pursuant to the parties’ stipulation, which obviated
the need for foundational testimony by a witness with personal knowledge. And to
the extent that Patterson raises a relevance challenge to Exhibits 81 and 440, the
district court’s decision to admit them was reasonably supported by the record. The
district court did not err in admitting Exhibit 413 based on lack of personal knowledge
because Steele testified that she created the exhibit.
4. The government produced sufficient evidence to allow a reasonable juror to

Under new Federal Rule of Evidence 107, which took effect December 1,
2024, a “demonstrative aid” is now called an “illustrative aid,” the use of which is
governed by Rule 107. We use the term “demonstrative aid” and follow the law in
effect at the time of trial, while recognizing that new Rule 107(a) and Rule 403 adopt
substantially similar standards.

convict Patterson under 26 U.S.C. § 7201. The government produced evidence that
a BDA was performed, consisting of (1) a spreadsheet listing all deposits made into
24 bank accounts for Patterson and the companies he owned during the relevant tax
years; (2) Steele’s testimony about the steps she took to analyze the deposits; and (3)
summary charts reflecting the conclusions of Steele’s analysis. The absence of
documentary proof of the intermediate steps that Steele completed does not mean that
no analysis occurred or that no BDA exists. See United States v. Boulware, 384 F.3d
794, 811 (9th Cir. 2004) (explaining that BDA performer’s testimony detailing
procedure and methodology can constitute sufficient evidence that government
conducted “adequate and full investigation” of defendant’s accounts). And Steele’s
failure to calculate Patterson’s “cash on hand” did not render the BDA insufficient
because the government’s evidence, if credited by the jury, allowed a rational juror
to find that the government adequately accounted for “cash on hand” by
demonstrating that it was immaterial. Ultimately, for purposes of determining
whether the evidence was sufficient to convict Patterson, the precise amount of the
taxes that Patterson evaded is inconsequential; it is enough that the government
produced sufficient evidence for a rational juror to find that Patterson evaded some
quantum of tax. See United States v. Marashi, 913 F.2d 724, 735 (9th Cir. 1990)
(quoting 26 U.S.C. § 7201) (“The language of § 7201 does not contain a substantiality
-4-
requirement. It simply states that willful attempts to evade ‘any tax’ under the Tax
Code is a felony.”).
5. The district court did not err at sentencing in applying a “sophisticated
means” enhancement under U.S.S.G. §§ 2T1.1 and 2T1.4. Steele testified that the
government had to undertake the laborious exercise of subpoenaing 24 bank accounts
and analyzing the thousands of deposit records associated with them to perform the
BDA, which indicates that Patterson used sophisticated means to carry out his
offenses. See United States v. Jennings, 711 F.3d 1144, 1147 (9th Cir. 2013). And
the government’s evidence of methods that Patterson used to conceal income—asking
customers to make checks out to him personally, failing to record some of his business
income, providing incomplete financial records to his tax preparers, and instructing
Patterson’s companies’ secretary/bookkeeper to get rid of financial
records—supported application of the enhancement, even if the district court did not
explicitly refer to that evidence.
6. The district court did not clearly err in its factual findings when determining
the amount of tax loss. The district court’s findings were not “illogical, implausible,
or without support in the record.” United States v. Sanmina Corp., 968 F.3d 1107,
1116 (9th Cir. 2020) (citation omitted).
AFFIRMED.

United States v. Patterson, No. 23-631 FILED
COLLINS, Circuit Judge, dissenting: DEC 31 2024
MOLLY C. DWYER, CLERK
U.S. COURT OF APPEALS
Defendant-Appellant Ryan Patterson was charged in a three-count
indictment with having willfully evaded his income taxes by signing and
submitting false tax returns for 2014, 2015, and 2016. See 26 U.S.C. § 7201. He
was convicted after a jury trial and sentenced to 20 months in prison. Because I
conclude that his convictions were the result of prejudicial evidentiary error, I
would reverse and remand for a new trial. I therefore respectfully dissent from the
majority’s judgment affirming Patterson’s convictions and sentence.
At trial, the Government relied on “a bank-deposits method of proof” to
establish that Patterson had substantially underreported his income on the relevant
tax returns. United States v. Boulware, 384 F.3d 794, 811 (9th Cir. 2004). We have
described the requirements of that method of proof as follows:
When using the bank-deposits method of proof, the
government must conduct an adequate and full investigation to
remove non-income deposits, such as transfers between bank
accounts. “The critical question is whether the government’s
investigation has provided sufficient evidence to support an
inference that an unexplained excess in bank deposits is
attributable to taxable income.” Although the government
must be especially thorough in its investigation and
presentation, “it is well settled that the government is not
obliged to prove the exact amount of a deficiency so long as
the taxpayer’s understatement of income is substantial.”
Id. (citations omitted). Although the Government here was arguably “thorough in
its investigation” concerning “non-income deposits,” it was far from “thorough in
its . . . presentation” on that score at trial. Id. In my view, the key evidence on
which the Government’s bank-deposit analysis was based did not satisfy the
requirements of the Federal Rules of Evidence, and Patterson’s motion to strike
that evidence should have been granted in full.
At trial, the Government presented the testimony of IRS Agent Debra Steele,
who explained the general method she applied in performing her bank-deposit
analysis. After the voluminous bank records had been scanned into an Excel
spreadsheet, Steele separated the bank deposits that she thought were not income
from those that she thought were income by moving the non-income items to the
bottom of the spreadsheet. She then totaled up the remaining income deposits at
the top of the spreadsheet, and she wrote down the resulting number, which she
considered to be the “gross receipts,” on a “sticky note.” She then deducted the
full expenses claimed by Patterson in order to determine what she believed to be
Patterson’s net profit or loss. She then created two charts, one comparing the gross
receipts listed on each of Patterson’s returns with the total gross receipts she
calculated for each year, and the other comparing the net profit or loss shown on
the returns with her calculations of net profit. Steele admitted, however, that she
did not save the Excel spreadsheet that showed how she divided the various line
entries of bank deposits into those that she believed were income deposits and
2
those that she believed were non-income deposits. Steele only had her bottom-line
gross-receipt and net-profit numbers for each of the three years, and those numbers
were listed on her two charts (which were initially admitted into evidence) and
were orally read by her into the record.
Patterson moved to strike Steele’s testimony and the two exhibits, relying
principally on Rules 1006 and 403. The district court granted the motion as to the
two charts, but not as to Steele’s testimony. The court held that the charts were not
admissible as summaries of voluminous evidence under Rule 1006 because, given
that Steele did not save any of her work, there was no record as to which of the
voluminous bank-record entries were being summarized. But the court held that
Steele’s oral testimony was “[u]ngoverned by Rule 1006” and that the same
analysis therefore did not apply to that testimony. The court thus allowed Steele’s
testimony to stand, but it withdrew the two charts from evidence and instead
classified them as permissible non-evidence demonstratives.
I agree with the district court’s ruling that the summary charts did not
comply with Rule 1006. That rule states that the proponent of a “summary, chart,
or calculation” concerning the “content of voluminous writings” “must make the
originals or duplicates” of the underlying materials available to the “other parties at
a reasonable time and place.” FED. R. EVID. 1006 (2023). The district court
correctly held that this requirement is not satisfied if the proponent does not
3
identify what portions of the content of which documents are being summarized.
Cf. FED. R. EVID. 1006, advis. comm. note (2004 amend.) (reaffirming that the
purpose of the production requirement is to “ensure that all parties have a fair
opportunity to evaluate the summary”).
Moreover, the proponent has not adequately laid a foundation for the
summary, chart, or calculation unless the proponent can show the work, so to
speak, that underlies it. “Rule 1006 evidence by its very nature embodies an
opinion that it accurately interprets or summarizes the contents of the voluminous
source material,” and where that evidence is presented “in the form of a lay
opinion, as it usually will be, Federal Rule of Evidence 701 applies and the
proponent must show that the opinion is rationally based on the perception of the
witness and helpful to the trier of fact.” 31 CHARLES ALAN WRIGHT AND VICTOR J.
GOLD, FEDERAL PRACTICE AND PROCEDURE § 8043, at p. 535 (2d ed. 2021)
(hereinafter “WRIGHT AND GOLD”). In my view, the underlying opinions behind
the summaries and calculations in Steele’s charts have not been shown to be
“rationally based on the perception of the witness and helpful to the trier of fact,”
given that—as the district court recognized here—“she didn’t keep a record
precisely of which ones she included and which ones she disregarded, [and] more
importantly, the jury doesn’t know which ones.” To support the opinions
underlying these calculations, Steele had to provide sufficient intermediate detail to
4
the jury about how her methods were actually applied to this enormous mass of
data (e.g., perhaps by tallying up the various subcategories of income items and
non-income items and defining more clearly the criteria for classifying a given
entry as falling into a particular subcategory). Additionally, Steele should have
supplied all of the supporting detail on which she relied to Patterson, and the
failure to do so here denied him “effective cross-examination.” Square Liner 360,
Inc. v. Chisum, 691 F.2d 362, 376 (8th Cir. 1982). Effectively, what the
Government did at Patterson’s trial was to ask the jury to accept, based on Steele’s
barebones say-so, that she had determined that Patterson underreported his income.
The rules of evidence require more than this sort of take-my-word-for-it approach.
Although the district court thus correctly withdrew the charts from evidence,
the court erred in holding that the same analysis did not apply to Steele’s oral
testimony. Nothing in the text of Rule 1006 limits its applicability to physical
exhibits, and Steele’s oral recitation of her bottom-line calculations was “a
summary . . . or calculation to prove the content of voluminous writings” within
the plain language of the rule. Indeed, we have squarely held that “a summary,
either oral or written, may be received in evidence,” but “the summary must meet
the requirements of Rule 1006.” United States v. Aubrey, 800 F.3d 1115, 1130 (9th
Cir. 2015) (citation omitted); see also Square Liner 360, Inc., 691 F.2d at 376 (“We
are satisfied that protection of the integrity of Rule 1006 requires its application to
5
Chisholm’s oral testimony from his summaries and calculations.” (citing United
States v. Johnson, 594 F.2d 1253 (9th Cir. 1979)); Johnson, 594 F.2d at 1257
(applying Rule 1006 in holding “that the district court improperly allowed the
Government to ask Mr. Harbert about the summary” (emphasis added)); see also
31 WRIGHT AND GOLD, supra, § 8044, at pp. 545–46 (“While a chart is necessarily
in tangible form, summaries and calculations may be in tangible form or may be
presented as testimony” (footnotes omitted)). Indeed, the distinction drawn by the
district court makes no sense, because it would allow the proponent of a summary
to evade the strictures of Rule 1006 through the simple expedient of having the
witness orally recite the summaries and calculations.
Because the district court erred in admitting the testimony of Steele as to her
calculations, the convictions should be reversed. On this record, it is likely that
Steele’s critical testimony, which occupied more than a day of the trial, was relied
upon by the jury in concluding that Patterson had underreported his income. The
error therefore cannot be deemed to be harmless. See United States v. Mirabal, 98
F.4th 981, 987 (9th Cir. 2024) (“We may only conclude that an error was harmless
if it is ‘more probable than not that the erroneous admission of the evidence did not
affect the jury’s verdict.’”) (citations omitted)).
Because I would reverse Patterson’s convictions on this ground, I need not
reach any other issue raised on appeal except for Patterson’s challenge to the
6
sufficiency of the evidence. See United States v. Irons, 31 F.4th 702, 715 (9th Cir.
2022). However, in evaluating the sufficiency of the evidence, we must consider
all of the evidence before the jury, including evidence that was improperly
admitted. See id. (citing Lockhart v. Nelson, 488 U.S. 33, 40–41 (1988)). Even
though I think that Steele’s testimony lacked an adequate foundation and lacked
sufficient explanatory detail to be helpful to the jury, it was still some evidence of
underreporting of income. And, importantly, it was not the only evidence of
underreporting. The bookkeeper for Patterson’s businesses testified that some
business payments were made by personal check to Patterson and were omitted
from the software records provided to Patterson’s tax preparers and that some
payments were made in cash and were “under the table” payments. This is enough
evidence to permit a rational jury to find Patterson guilty under “the lenient
standard for evidentiary sufficiency.” See id. at 716 (stating that “the relevant
question is whether, after viewing the evidence in the light most favorable to the
prosecution, any rational trier of fact could have found the essential elements of the
crime beyond a reasonable doubt” (citation omitted)).
For the foregoing reasons, I dissent from the affirmance of Patterson’s
convictions and sentence. I would reverse and remand for a new trial.
