Opinion by Chief Judge Murguia
SUMMARY *
Criminal Law
In codefendant brothers Joshua and Jamie Yafa’s appeals
from their convictions and sentences for securities fraud and
conspiracy to commit securities fraud for their involvement
in a “pump-and-dump” stock manipulation scheme, the
panel affirmed the district court’s reliance on Application
Note 3(B) in the commentary to United States Sentencing
Guidelines § 2B1.1, which, at the time the Yafas were
sentenced, instructed courts to use the gain that resulted from
the defendant’s offense as an alternative measure for
calculating loss where loss cannot reasonably be determined.
Applying the analysis set forth in Kisor v. Wilkie, 588
U.S. 558 (2019), to determine whether deference to the
commentary’s interpretation of a Guideline is appropriate,
the panel held (1) the term “loss” is genuinely ambiguous,
(2) Application Note 3(B)’s instruction to use gain is a
reasonable interpretation of “loss,” and (3) the character and

context of Application Note 3(B) entitles it to controlling
weight.
The panel concluded accordingly that Application Note
3(B)’s interpretation of “loss” warrants deference, and that
the district court did not err when it used the gain that
resulted from the Yafas’s offenses as an alternative measure
for loss.
In a concurrently filed memorandum disposition, the
panel resolved the Yafas’s additional challenges to their
convictions and sentences.

4 USA V. YAFA
OPINION
MURGUIA, Chief Circuit Judge:
Following a jury trial, codefendants and brothers Joshua
and Jamie Yafa (the “Yafas”) were convicted of one count
each of securities fraud and conspiracy to commit securities
fraud for their involvement in a “pump-and-dump” stock
manipulation scheme. At sentencing, the district court relied
on Application Note 3(B) in the commentary to United
States Sentencing Guidelines (“U.S.S.G.”) § 2B1.1, which
instructs courts to use the gain that resulted from the
defendant’s offense as an alternative measure for calculating
loss where loss cannot reasonably be determined. U.S.S.G.
§ 2B1.1 cmt. n.3(B). 1 On appeal, the Yafas contend that it
was legal error to defer to § 2B1.1’s commentary because
the term “loss” is not genuinely ambiguous. Because we
hold that deference is appropriate, we conclude that the
district court did not err when it relied on the commentary
and used “gain” as an alternative measure for the “loss”
attributable to the Yafas. 2
I
In 2019, Charles Strongo acquired Global Wholehealth
Products Corporation (“GWHP”), a struggling medical

The United States Sentencing Commission recently amended the
relevant Guidelines provision and commentary. Because the Yafas were
sentenced before these revisions became effective, the parties agree the
revisions do not apply to this case. Accordingly, all citations to the
Guidelines and commentary in this opinion are to the versions in effect
prior to the recent amendments, unless otherwise specified.

manufacturing company. Later that year, Strongo partnered
with Brian Volmer, who began raising funds for the
company through outside investors and introduced Strongo
to the Yafas, two brothers who worked as stock promoters.
Because GWHP purported to manufacture medical test kits,
the associates saw an opportunity to make a significant
amount of money from the company’s stock when the
COVID-19 pandemic struck in March 2020.
Strongo, Volmer, and the Yafas proceeded to engage in
a “pump-and-dump” stock manipulation scheme. First, the
“pump.” Having gained substantial control over GWHP’s
freely tradable stock, Strongo worked with Volmer and
Joshua Yafa to increase the number of GWHP shares that
were trading on the open market to legitimize the stock in
the eyes of potential investors. The Yafas then promoted the
stock using a “phone room,” where operators called potential
investors to push GWHP stock, and various forms of social
media including email blasts and newsletters.
Second, the “dump.” When GWHP stock had risen in
price from fifty cents to two dollars per share, the scheme
participants began gradually selling their shares. By March
2021, the Yafas and entities they controlled had sold enough
GWHP shares to collectively earn over $1 million.
Following the “dump,” the price of GWHP stock declined
significantly. Individual investors who acquired GWHP
stock while the price was artificially inflated lost their
investments. A grand jury subsequently indicted Strongo,
Volmer, and the Yafas for their roles in the scheme. Strongo
and Volmer pled guilty and testified against the Yafas at
their 2023 trial, where the jury found the Yafas guilty of one
count each of securities fraud and conspiracy to commit
securities fraud.
6 USA V. YAFA
At sentencing, the district court applied U.S.S.G.
§ 2B1.1(b)(1), which increases a defendant’s offense level
depending on the amount of “loss” resulting from the fraud
committed. The Guidelines do not define “loss,” but at the
time the Yafas were sentenced, Application Note 3(B) in the
commentary to § 2B1.1 instructed courts to “use the gain
that resulted from the offense as an alternative measure of
loss” where loss “reasonably cannot be determined.” 3
The district court found that the “full amount of investor
losses would be exceedingly difficult to calculate,” and
therefore relied on “gain as a proxy for a portion of the total
loss” attributable to the Yafas’s criminal activities pursuant
to Application Note 3(B). Relying on evidence from trial,
the district court combined the gains attributable to each
brother with the actual loss established by the Government
to arrive at total loss amounts of $942,099.70 for Joshua, and
$607,696.70 for Jamie. Based on the graduated table in
U.S.S.G. § 2B1.1(b)(1), the district court therefore applied a
fourteen-level increase to each brother’s offense level.
After the fourteen-level enhancements were applied,
Joshua’s adjusted offense level was twenty-one and Jamie’s
was nineteen, resulting in a guideline range of thirty-seven
to forty-six months for Joshua and thirty to thirty-seven
months for Jamie. The district court then varied downward
from the brothers’ Guideline ranges and sentenced Joshua to
thirty-two months of imprisonment and Jamie to seventeen
months. The Yafas timely appealed.
3
On November 1, 2024, amendments to the Guidelines became
effective, moving this commentary on “gain” into the text of § 2B1.1
itself. See U.S.S.G. § 2B1.1(b)(1)(B) (Nov. 2024).

II
We have jurisdiction pursuant to 28 U.S.C. § 1291 and
review the Yafas’s challenge to the district court’s
interpretation of U.S.S.G. § 2B1.1 de novo. United States v.
Castillo, 69 F.4th 648, 652 (9th Cir. 2023).
III
Because the Yafas were sentenced before Application
Note 3(B) was moved from the commentary to the
Guidelines, we must determine whether the district court’s
reliance on the commentary was appropriate. To determine
whether it is appropriate to defer to the commentary’s
interpretation of a Guideline, we apply the analysis set forth
in Kisor v. Wilkie, 588 U.S. 558 (2019). Castillo, 69 F.4th
at 655–56. 4 Kisor instructs that courts owe deference to an
agency’s interpretation of its own rules where (1) the
regulation is “genuinely ambiguous,” (2) the interpretation
is “reasonable,” and (3) the interpretation is entitled to
“controlling weight.” 588 U.S. at 574–79. Section 2B1.1’s
commentary instructing courts to use gain as an alternative
measure of loss satisfies these requirements.
A
First, the term “loss” is genuinely ambiguous. A court
may only conclude that a regulation is genuinely ambiguous
after “exhaust[ing] all the traditional tools of construction.”
Id. at 575 (internal quotation marks omitted). In other
words, it must consider “the text, structure, history, and

purpose of a regulation, in all the ways it would if it had no
agency to fall back on.” Id. Although “[w]e have not
previously held that the term ‘loss’ under § 2B1.1 is
genuinely ambiguous,” United States v. Hackett, 123 F.4th
1005, 1012 (9th Cir. 2024), several of our sister circuits have
reached this conclusion applying Kisor. See, e.g., United
States v. You, 74 F.4th 378, 397–98 (6th Cir. 2023) (holding
that “loss” is genuinely ambiguous); United States v. Boler,
115 F.4th 316, 328–29 (4th Cir. 2024) (same). But see
United States v. Banks, 55 F.4th 246, 257–58 (3d Cir. 2022)
(holding that the ordinary meaning of “loss” controls).
Beginning with the text of § 2B1.1, dictionaries support
“no one definition” of the term “loss” but rather demonstrate
that it “can mean different things in different contexts.” You,
74 F.4th at 397; see United States v. Kirilyuk, 29 F.4th 1128,
1137 (9th Cir. 2022) (“[A] review of dictionaries reveals that
‘loss’ can have a range of meanings . . . .”). In the economic
context, for example, a reasonable person might define
“loss” narrowly as an “amount lost” whereas another may
use the term to express more broadly the entire “detriment or
disadvantage involved in being deprived of something.”
Loss, OXFORD ENG. DICTIONARY,
https://www.oed.com/dictionary/loss_n1?tab=meaning_and
_use#38877144 (last visited May 8, 2025); see Boler, 115
F.4th at 324–25 (“These multiple and varied definitions
alone demonstrate that ‘loss’ could mean a number of
different things depending on the dictionary of one’s
choice.”). Accordingly, “uncertaint[y]” remains following a
plain reading of the term “loss.” Kisor, 588 U.S. at 566.
Nor do the Guidelines’ structure or the context in which
the term “loss” is used resolve this ambiguity. The relevant
conduct Guideline, which guides courts in determining the
offense level based on the defendant’s conduct, directs
USA V. YAFA 9
courts to consider “all harm that resulted from” the criminal
activity. U.S.S.G. § 1B1.3(a)(3) (emphasis added). Read
alongside § 2B1.1, § 1B1.3’s broad directive, which does
not define or limit “harm,” adds further ambiguity to the
term “loss” and, at the very least, strongly suggests that
“loss” is not limited to only that loss which is identifiable
and clearly calculable, as the Yafas contend. See Boler, 115
F.4th at 325–26.
Section 2B1.1’s history and purpose confirm that the
term “loss” is “susceptible to more than one reasonable
reading.” Kisor, 588 U.S. at 566. The Guidelines explain
that the purpose of estimating “loss” is to assess “the
seriousness of the offense and the defendant’s relative
culpability.” U.S.S.G. § 2B1.1, cmt. (background). The
Yafas’s narrow interpretation would hamstring courts in
fulfilling this purpose and prevent them from adequately
assessing a defendant’s culpability in fraud convictions
where actual loss may be difficult to assess. See Boler, 115
F.4th at 327. And historically, since the very first manual
was published in 1987, the Guidelines commentary has
advised courts to use gain as an alternative measure for loss.
See U.S.S.G. § 2F1.1, cmt. n.8 (1987). Accordingly,
because no single meaning of “loss” is evident from
§ 2B1.1’s text, even after employing the traditional tools of
interpretation, a genuine ambiguity exists.
B
Second, Application Note 3(B)’s instruction to use gain
is a reasonable interpretation of “loss.” An agency’s
interpretation is reasonable if it “come[s] within the zone of
ambiguity the court has identified after employing all its
interpretive tools.” Kisor, 588 U.S. at 575–76. As the
foregoing analysis demonstrates, the zone of ambiguity for
10 USA V. YAFA
the term “loss” stretches, at a minimum, along a spectrum
from the actual, calculable loss experienced by victims of an
economic crime to the far broader harms involved in and
arising out of a defendant’s criminal conduct. Application
Note 3(B) falls within this range. Because federal theft and
fraud statutes can “cover a broad range of conduct,”
U.S.S.G. § 2B1.1, cmt. (background), relying on the amount
of gain enables courts to “maintain[] sufficient flexibility”
and issue sentences that “avoid[] unwarranted sentencing
disparities among defendants . . . who have been found
guilty of similar criminal conduct,” even where the actual
loss resulting from a defendant’s conduct is difficult to
calculate, 28 U.S.C. § 991(b)(1)(B).
Further, despite the Yafas’s contention to the contrary,
Application Note 3(B)’s interpretation does not expand the
definition of “loss.” See Banks, 55 F.4th at 258 (concluding
that Application Note 3(A) “expands the definition of ‘loss’
by explaining that generally ‘loss is the greater of actual loss
or intended loss’”). Unlike Application Note 3(A)’s
instruction that sentencing courts must rely on the loss a
defendant intended to cause where intended loss is greater
than actual loss, Application Note 3(B) merely provides
courts with another method to determine the actual loss
resulting from a defendant’s conduct. 5
C
Finally, the character and context of Application Note
3(B) “entitles it to controlling weight.” Kisor, 588 U.S. at
576. While this inquiry “does not reduce to any exhaustive
5
We note that our conclusion is limited to Application Note 3(B) and
says nothing about the reasonableness of Application Note 3(A)’s
instruction defining loss as the “greater of actual loss or intended loss.”

test,” Kisor instructs courts to consider whether the
interpretation (1) constitutes the agency’s “official position,
rather than any more ad hoc statement not reflecting the
agency’s views,” (2) implicates the agency’s “substantive
expertise,” and (3) reflects the agency’s “fair and considered
judgment.” Id. at 576–79 (internal quotation marks and
citations omitted).
The commentary is issued by the Commission as its
official position. Trumbull, 114 F.4th at 1120. And, given
the careful consideration and “ample research” the
Commission undertakes and publishes each year in respect
to § 2B1.1 crimes, the commentary implicates the
Commission’s substantive expertise and reflects its fair and
considered judgment. Boler, 115 F.4th at 328. Further,
Application Note 3(B) has been a part of the Guidelines
since their inception and does not therefore reflect a
“convenient litigating position” or “new
interpretation . . . that creates ‘unfair surprise’ to regulated
parties.” Kisor, 588 U.S. at 579 (citation omitted).
Accordingly, the three “especially important markers”
identified by the Supreme Court confirm that deference is
warranted. Id. at 576.
IV
Application Note 3(B)’s interpretation of “loss” warrants
deference under Kisor. Therefore, the district court did not
err when it used the gain that resulted from the Yafas’s
offenses as an alternative measure for loss.
AFFIRMED.
