    UNITED STATES v. BERGER                       15621
    OPINION
    MILAN D. SMITH, JR., Circuit Judge:
    Defendant-Appellant Richard I. Berger appeals the sen-
    tence imposed by the district court following our affirmance
    of his conviction for twelve counts of bank and securities
    fraud. Berger argues that, in sentencing him on remand, the
    district court erred by: (1) not adhering to the civil loss causa-
    tion principle in finding shareholder loss, as described by the
    Supreme Court in Dura Pharmaceuticals, Inc. v. Broudo, 
    544 U.S. 336
    , 342-48 (2005); and (2) applying an erroneous stan-
    dard of proof in determining total loss for sentencing
    enhancement purposes. While we decline to extend the Dura
    Pharmaceuticals principle to criminal securities fraud, we
    conclude that the district court’s loss calculation approach
    was nevertheless flawed. Thus, although we conclude that the
    district court used the correct standard of proof in determining
    the total loss, we vacate Berger’s sentence and remand to the
    district court for resentencing.
    FACTS AND PROCEDURAL BACKGROUND
    Craig Consumer Electronics, Inc. (Craig) was a publicly
    traded consumer electronics business that primarily distrib-
    uted its products to retail electronics stores. During the rele-
    vant time frame, Berger was Craig’s President, Chief
    Executive Officer, and Chairman of the Board. Two other
    corporate officers, Donna Richardson and Bonnie Metz,1 par-
    ticipated in the fraudulent scheme and were convicted along
    with Berger for their involvement.
    In August 1994, Craig entered into a $50 million revolving
    1
    Richardson, Craig’s Chief Financial Officer until May 31, 1997, pled
    guilty to three counts of the indictment prior to trial. Metz was at various
    times a Vice President in Craig’s Hong Kong and Cerritos, California
    locations.
    15622                 UNITED STATES v. BERGER
    credit agreement with a consortium of banks. Under the
    agreement, the amount Craig was permitted to borrow was
    based on the value of its current inventory and accounts
    receivable. To determine the fluctuating amount Craig was
    eligible to borrow, Berger and his co-defendants were
    required to provide the lending banks with a daily certifica-
    tion concerning those assets.
    Berger and his accomplices began the fraudulent scheme as
    early as 1995.2 Starting at that time and continuing through
    September 1997, Craig lacked sufficient qualifying accounts
    receivable and inventory to continue borrowing the funds
    needed for Craig’s ongoing operations. To conceal Craig’s
    true financial condition from the lending banks, Berger and
    his cohorts employed various accounting schemes to falsify
    the information contained in the certifications. Relying on
    these false statements, the banks lent millions of dollars to
    Craig based on either nonexistent or substantially overstated
    collateral.
    In May 1996, Craig made an initial public offering (IPO)
    of its stock. In connection with the IPO, Berger publicly mis-
    represented the company’s fiscal viability, misstating Craig’s
    financial condition in several mandatory reports filed with the
    Securities and Exchange Commission (SEC). At the time of
    the IPO, Craig was actually operating in default of its credit
    agreement with the lending banks, and was substantially over-
    drawn on its credit line. None of this information was dis-
    closed in Craig’s mandatory SEC filings, or to its lenders.
    In 1997, an audit of the company’s records by Craig’s
    accounting firm uncovered various accounting irregularities.
    As a result of the audit, Craig was required to restate its earn-
    ings for 1995 and part of 1996, thereby revealing that its earn-
    2
    Our prior decision in this case provides a more detailed description of
    the scheme. See United States v. Berger, 
    473 F.3d 1080
    , 1083-85 (9th Cir.
    2007).
    UNITED STATES v. BERGER                       15623
    ings were substantially lower than those shown in its previous
    financial statements. In the months following this restatement,
    Craig’s stock price fell from $4.99 to $0.99 per share.3 In July
    1997, Craig’s stock was delisted from the Nasdaq because of
    its failure to meet Nasdaq’s minimum bid price. The securities
    fraud and accounting irregularities noted were not publicly
    revealed until after the delisting. The lending banks did not
    discover the full extent of the fraud until August 1997, when
    Craig filed for bankruptcy.
    In March 2003, Berger was indicted for thirty-six counts of
    bank and securities fraud including: conspiracy, loan fraud,
    falsification of corporate books and records, making false
    statements to accountants of a publicly traded company, and
    making false statements in reports filed with the SEC. Berger
    went to trial and was convicted on twelve of those counts. In
    September 2004, the district court, believing controlling
    authority prohibited it from applying any sentencing facts not
    found by the jury, calculated an applicable sentencing range
    of zero to six months and sentenced Berger to six months
    imprisonment. The district court also ordered Berger to pay
    restitution of $3.14 million and a $1.25 million fine. Berger
    appealed his conviction and restitution order, and the govern-
    ment cross-appealed the sentence.
    We affirmed the conviction and the restitution amount.
    However, we vacated Berger’s sentence and remanded to the
    district court for resentencing in light of United States v.
    Booker, 
    543 U.S. 220
     (2005). On remand, using a preponder-
    ance of the evidence standard, the district court found several
    facts that significantly increased Berger’s sentencing range.4
    Among other things, the district court found that Berger’s
    fraud caused a loss of $3.14 million to the various banks with
    3
    It is unclear the extent to which this decline resulted from the restated
    earnings, as opposed to unrelated external market forces or other factors.
    4
    The district court used the 1995 version of the Sentencing Guidelines
    to avoid creating a potential ex post facto problem.
    15624                 UNITED STATES v. BERGER
    which Craig did business, thereby triggering a thirteen-level
    enhancement under U.S.S.G. § 2F1.1.
    To determine the loss to shareholders, the court adopted
    one of the government’s suggested calculation methods, the
    so-called “modified market capitalization theory,” i.e., com-
    paring the change in stock value of other, unaffiliated compa-
    nies after accounting irregularities in those companies’
    records were disclosed to the market. The court determined
    that the average depreciation of those selected companies’
    stock was 26.5% and applied that figure to the value of
    Craig’s initial public offering (although in Craig’s case, the
    fraud was never disclosed to the market before trading was
    halted). The court calculated the resulting shareholder loss at
    $2.1 million.
    Therefore, the total calculated loss was $5.2 million, which
    triggered a fourteen-level sentencing enhancement, from level
    sixteen to thirty. This enhancement increased the applicable
    sentencing range from 21-27 months to 97-121 months. The
    district court imposed a 97-month sentence. Berger appeals
    the sentence, arguing that the district court committed two
    significant legal errors in calculating the applicable sentenc-
    ing range.
    JURISDICTION AND STANDARD OF REVIEW
    We have jurisdiction pursuant to 
    28 U.S.C. § 1291
    . We
    review de novo the district court’s interpretation of the Sen-
    tencing Guidelines, United States v. Kimbrew, 
    406 F.3d 1149
    ,
    1151 (9th Cir. 2005), which are relevant to this case because
    the Guidelines address the permissible methods for loss calcu-
    lation. We review for abuse of discretion the district court’s
    application of the Guidelines to the facts of this case.5

    But see United States v. Williamson, 
    439 F.3d 1125
    , 1137 n.12 (9th
    Cir. 2006) (“We review . . . application of the Guidelines de novo.”
    (emphasis added)). Because we conclude that the district court’s applica-
    tion of the Guidelines in calculating loss was erroneous under either de
    novo or abuse of discretion review, we do not attempt to resolve this con-
    flict in our case law.
    UNITED STATES v. BERGER                15625
    the district court makes a material miscalculation in the advi-
    sory guidelines range, . . . we must vacate the sentence and
    remand for resentencing.” United States v. Zolp, 
    479 F.3d 715
    , 721 (9th Cir. 2007). Whether the district court violated
    due process by using an improper standard of proof is a ques-
    tion of constitutional law that we review de novo. United
    States v. Johansson, 
    249 F.3d 848
    , 853 (9th Cir. 2001).
    DISCUSSION
    Berger raises two issues on appeal. First, he argues that in
    calculating loss in securities fraud cases, district courts must
    employ the civil securities fraud “loss causation” approach as
    described in Dura Pharmaceuticals, 
    544 U.S. 336
    , and that
    the district court erred by not doing so here. He also contends
    that the district court erred in finding facts resulting in a sig-
    nificant sentencing enhancement by a preponderance of the
    evidence—rather than a clear and convincing evidence—
    standard of proof.
    I.    Loss Causation Principles Applied to Criminal
    Securities Fraud
    Berger first argues that the district court erred by including
    losses in its $2.1 million shareholder loss figure that did not
    actually occur, or that were not caused by his fraudulent con-
    duct.
    A.   Civil Securities Fraud Standard
    [1] The Supreme Court has ruled that to sustain a damages
    claim for civil securities fraud under 15 U.S.C. §§ 78j(b) and
    78u-4, a plaintiff must show that the fraud was publicly
    revealed and that the disclosure caused the shareholders to
    suffer loss. Dura Pharms., 
    544 U.S. at 346-47
     (finding that
    plaintiff must show that “share price fell significantly after the
    truth [of the fraud] became known”). In so holding, the Dura
    Pharmaceuticals Court rejected the notion that stock over-
    15626               UNITED STATES v. BERGER
    valuation resulting from so-called “fraud-on-the-market” may
    form the basis for a plaintiff’s damages award in a private
    securities action. 
    Id. at 341-43
    . In other words, a sharehold-
    er’s allegation that he was led to buy stock at a price that was
    artificially inflated due to fraud does not state a claim for loss.
    
    Id.
     (noting that while “one might say that the inflated pur-
    chase price suggests that the misrepresentation . . . ‘touches
    upon’ a later economic loss” that is insufficient because “[t]o
    ‘touch upon’ a loss is not to cause a loss” (internal citations
    omitted) (citing 15 U.S.C. § 78u-4(b)(4))). As a result, it is
    now clear in civil securities fraud actions that “the complaint
    must allege that the practices that the plaintiff contends are
    fraudulent were revealed to the market and caused the result-
    ing losses.” Metzler Inv. GMBH v. Corinthian Colls., Inc.,
    
    540 F.3d 1049
    , 1063 (9th Cir. 2008).
    B. Application of Civil Rule to Criminal Securities
    Fraud
    [2] The Supreme Court has not applied its Dura Pharma-
    ceuticals loss causation principle to sentencing enhancements
    in criminal securities fraud cases, but two federal circuit
    courts have suggested that they are applicable in this context.
    In United States v. Olis, the Fifth Circuit intimated that the
    civil loss causation principle described in Dura Pharmaceuti-
    cals should inform criminal securities fraud sentencing. See
    Olis, 
    429 F.3d 540
    , 546 (5th Cir. 2005) (“The civil damage
    measure should be the backdrop for criminal responsibility
    both because it furnishes the standard of compensable injury
    for securities fraud victims and because it is attuned to stock
    market complexities.”) (citing Dura Pharms., 
    544 U.S. 336
    ,
    341-43). Olis cited several out-of-circuit cases, including vari-
    ous so-called “cook the books” scenarios, and noted with
    approval that “each case takes seriously the requirement to
    correlate the defendant’s sentence with the actual loss caused
    in the marketplace, exclusive of other sources of stock price
    decline.” Id. at 547.
    UNITED STATES v. BERGER                     15627
    And in United States v. Rutkoske, the Second Circuit
    endorsed the application of Dura Pharmaceuticals’s principle
    to criminal sentencing even more strongly, stating that:
    [t]he Government contends that the principles set
    forth in Dura Pharmaceuticals, a civil case, should
    not apply to loss calculation in a criminal case. The
    dicta in [our decision in United States v. Ebbers, 
    458 F.3d 110
    , 128 (2d Cir. 2006)] strongly undermines
    that position. Moreover, we see no reason why con-
    siderations relevant to loss causation in a civil fraud
    case should not apply, at least as strongly, to a sen-
    tencing regime in which the amount of loss caused
    by a fraud is a critical determinant of the length of
    a defendant’s sentence.
    
    506 F.3d 170
    , 179 (2d Cir. 2007).
    [3] This court has not applied Dura Pharmaceuticals’s
    strict loss causation standard to criminal fraud cases, but we
    have endorsed a more general loss causation principle, per-
    mitting a district court to impose sentencing enhancements
    only for losses that “resulted from” the defendant’s fraud.
    United States v. Hicks, 
    217 F.3d 1038
    , 1048 (9th Cir. 2000).
    In Hicks, we stated that “[t]he Guidelines’ ‘relevant conduct’
    provision requires a defendant’s sentence to be based on ‘all
    harm that resulted from the acts or omissions’ of the defen-
    dant.” 
    Id.
     (quoting U.S.S.G. § 1B1.3(a)(3) (1995)); id. at
    1048-49 (holding that government must show both “but-for”
    and “proximate” causation in establishing loss).6 Berger now
    urges us to take the next step and follow the Second Circuit
    in expressly applying Dura Pharmaceuticals’s civil principle
    to criminal securities fraud sentencing.
    6
    The government in this case concedes that, “in order to be a basis for
    an increase in base offense level under the guidelines, the losses from
    defendant’s securities fraud offenses must have resulted from those
    offenses.”
    15628               UNITED STATES v. BERGER
    [4] We decline to do so for two reasons. First, we believe
    that the primary policy rationale of Dura Pharmaceuticals for
    proscribing overvaluation as a valid measure of loss does not
    apply in a criminal sanctions context. Second, application of
    Dura Pharmaceuticals’s civil rule to criminal sentencing
    would clash with the parallel principles in the Sentencing
    Guidelines, which have persuasive value in federal courts. See
    United States v. Staten, 
    466 F.3d 708
    , 710 (9th Cir. 2006)
    (holding that failure to consider Guidelines note in applying
    sentencing enhancement was reversible error).
    As noted, Dura Pharmaceuticals rejected the notion that an
    allegation by a private plaintiff that he purchased securities
    that were overvalued because of fraud is sufficient to state a
    damages claim for civil securities fraud. 
    544 U.S. at 342
    (reversing Broudo v. Dura Pharms., Inc., 
    339 F.3d 933
     (9th
    Cir. 2003)). A key component of the Court’s holding was that
    “as a matter of pure logic, at the moment the transaction takes
    place, the plaintiff has suffered no loss; the inflated purchase
    payment is offset by ownership of a share that at that instant
    possesses equivalent value.” 
    Id.
     Because “[s]hares are nor-
    mally purchased with an eye toward a later sale[,] . . . if, say,
    the purchaser sells the shares quickly before the relevant truth
    begins to leak out, the misrepresentation will not have led to
    any loss.” 
    Id.
     Moreover, the Court reasoned, “the common
    law has long insisted that a plaintiff in such a case show not
    only that had he known the truth he would not have acted but
    also that he suffered actual economic loss.” Id. at 343-44 (cit-
    ing e.g., Pasley v. Freeman, 100 Eng. Rep. 450, 457 (1789)).
    Thus, the Court was concerned principally with the plaintiff’s
    ability to show that he suffered actual loss caused directly—
    and exclusively—by the defendant’s fraudulent misrepresen-
    tation.
    The Dura Pharmaceuticals Court’s concern is not impli-
    cated in the criminal sentencing arena. As demonstrated, in a
    private civil fraud action, a court gauges loss from the per-
    spective of the plaintiff-victim, i.e., whether the plaintiff can
    UNITED STATES v. BERGER                       15629
    show the amount and cause of loss he sustained. Id. Because
    a civil plaintiff bears the burden to show loss, it is logical to
    require that the plaintiff show that any loss he sustained was
    attributable directly to devaluation caused by revelation of the
    defendant’s fraud. It likewise follows that a plaintiff’s mere
    allegation that he purchased overvalued stock is insufficient
    to state a claim, because the allegation does not by itself
    establish that the plaintiff personally incurred loss commensu-
    rate with the overvaluation.
    In criminal sentencing, however, a court gauges the amount
    of loss caused, i.e., the harm that society as a whole suffered
    from the defendant’s fraud. See, e.g., Zolp, 
    479 F.3d at 720
    .
    Whether and to what extent a particular individual suffered
    actual loss is not usually an important consideration in crimi-
    nal fraud sentencing. Therefore, where the value of securities
    have been inflated by a defendant’s fraud, the defendant may
    have caused aggregate loss to society in the amount of the
    fraud-induced overvaluation, even if various individual vic-
    tims’ respective losses cannot be precisely determined or
    linked to the fraud. As a result, the principle underlying the
    Dura Pharmaceuticals Court’s reluctance to allow mere over-
    valuation as a basis for establishing loss is generally not pres-
    ent in the criminal sentencing context, and we are not
    persuaded that it would be appropriate to expand the Dura
    Pharmaceuticals rule to the criminal sentencing context.7
    The Sentencing Guidelines provide further support for lim-
    iting the scope of Dura Pharmaceuticals’s loss causation rule
    in a criminal sentencing context. In arguing for this interpreta-
    7
    We note that, based on this reasoning, Dura Pharmaceuticals may be
    more relevant in the context of criminal restitution under, for instance, the
    Mandatory Victims Restitution Act of 1996 (MVRA), 18 U.S.C. § 3663A,
    which, unlike the sentencing enhancement scheme, focuses on harm to the
    victims as opposed to loss caused by the defendant. See, e.g., Berger, 
    473 F.3d at 1104
     (“The MVRA requires a defendant to pay restitution to a vic-
    tim who is ‘directly and proximately harmed as a result of’ the fraud.”
    (quoting 18 U.S.C. § 3663A(a)(2)).
    15630                 UNITED STATES v. BERGER
    tion, the government cites the commentary to the 1995 Guide-
    lines (the version applied at Berger’s sentencing), specifically
    its endorsement of a flexible approach to loss calculation in
    criminal sentencing.8 E.g., Zolp, 
    479 F.3d at 718-19
    . The gov-
    ernment notes that § 2F1.1 commentary note 8 of the 1995
    Guidelines9 states that:
    The court need only make a reasonable estimate of
    the loss, given the available information. This esti-
    mate, for example, may be based on the approximate
    number of victims and an estimate of the average
    loss to each victim, or on more general factors, such
    as the nature and duration of the fraud and the reve-
    nues generated by similar operation. The offender’s
    gain from committing the fraud is an alternative esti-
    mate that ordinarily will underestimate the loss.10
    In addition, the government contends that § 2F1.1 condones
    measuring loss by overvaluation. See U.S.S.G. § 2F1.1, cmt.
    n.7(a) (1995). That note states:
    [a] fraud may involve the misrepresentation of the
    value of an item that does have some value (in con-
    trast to an item that is worthless). Where, for exam-
    8
    The Guidelines, including those for enhancements purposes, “are ordi-
    narily applied in light of available commentary, including application
    notes.” Staten, 466 F.3d at 715 (citing United States v. Allen, 
    434 F.3d 1166
    , 1173 (9th Cir. 2006) (“The application notes to the Guidelines are
    exactly that—notes about when a particular Guideline applies and when
    it does not.”)).
    9
    Section 2F1.1 was repealed in 2001.
    10
    Similarly, the government points out that § 2B1.1 commentary note 3
    provides that:
    The court need only make a reasonable estimate of the loss, given
    the available information. This estimate, for example, may be
    based upon the approximate number of victims and the average
    loss to each victim, or on more general factors such as the scope
    and duration of the offense.
    UNITED STATES v. BERGER                    15631
    ple, a defendant fraudulently represents that stock is
    worth $40,000 and the stock is worth only $10,000,
    the loss is the amount by which the stock was over-
    valued (i.e., $30,000).
    Thus, were Dura Pharmaceuticals’s loss causation rule
    applied to criminal sentencing enhancements, that principle’s
    plain rejection of the overvaluation loss measurement method,
    see 
    544 U.S. at 343
    , would collide with Congress’s clear
    endorsement of that method, see U.S.S.G. § 2F1.1, cmt.
    n.7(a).
    [5] For these reasons, we decline to require, in finding facts
    relevant to sentencing, a showing that “share price fell signifi-
    cantly after the truth became known.” Dura Pharms., 
    544 U.S. at 347
    . We instead reiterate our broader rule that “[t]he
    Guidelines’ ‘relevant conduct’ provision requires a defen-
    dant’s sentence to be based on ‘all harm that resulted from the
    acts or omissions’ of the defendant.” Hicks, 
    217 F.3d at 1048
    (quoting U.S.S.G. § 1B1.3(a)(3) (1995)).
    C.     The District Court’s Loss Valuation Approach
    While the district court was not required to follow Dura
    Pharmaceuticals’s loss causation approach, the loss-
    calculation method it did employ troubles us; it leaves us with
    little confidence that the government demonstrated, by the
    applicable standard of proof,11 that shareholder loss occurred,
    let alone that approximately $2.1 million of loss occurred.
    [6] Though the Guidelines state that courts may employ
    various methodologies to determine loss and that loss need
    not be established with precision, the fact that “[t]he court
    need only make a reasonable estimate of the loss,” U.S.S.G.
    § 2B1.1, cmt. n.3, § 2F1.1, cmt. n.8, does not obviate the
    11
    As we discuss below, the standard in this case should be preponder-
    ance of the evidence.
    15632               UNITED STATES v. BERGER
    requirement to show that actual, defendant-caused loss
    occurred. Rather, the plain language of the Guidelines com-
    mentary merely indicates that, in arriving at the loss figure,
    some degree of uncertainty is tolerable.
    First, the Guidelines’ statement that the “estimate [of loss]
    . . . may be based on the approximate number of victims and
    an estimate of the average loss to each victim,” U.S.S.G.
    § 2F1.1, cmt. n.8, presupposes that the court has already
    determined that some defendant-caused loss occurred. Indeed,
    without any loss to victims, there would be nothing on which
    to base an estimate. In the same way, the fact that the loss
    estimate “may be based on . . . general factors, such as the
    nature and duration of the fraud and the revenues generated
    by similar operation,” id., or on the “offender’s gain from
    committing the fraud,” id., does not suggest that a court is
    relieved of the duty to determine that some loss actually
    occurred. Even the overvaluation method example in § 2F1.1
    commentary note 7(a) does not suggest that a showing of
    actual loss is unnecessary. That illustration provides a model
    for calculating the amount of loss where fraud caused the
    value of stock to decrease, but where the stock retained resid-
    ual value. The example assumes that the stockholders were
    left holding stock that depreciated because of the fraud. In
    sum, each of these possible methodologies assumes that some
    loss was proximately caused by the defendant, while recog-
    nizing that the amount of loss may not be easily measurable.
    [7] In determining that the shareholder loss was $2.1 mil-
    lion in this case, the district court employed a counterfactual
    approach. The method examined the effect on the stock value
    of other, unrelated companies after accounting irregularities
    were disclosed to the market. Using that method, the court
    determined that the average depreciation in value was 26.5%.
    That figure was applied to the value of Craig’s initial public
    offering. The court’s method appears to have assumed that
    defendant-caused shareholder loss existed, and only then pur-
    ported to measure that loss. Moreover, that measure of loss
    UNITED STATES v. BERGER                       15633
    was not based on Craig’s finances or on the actual effect of
    Berger’s fraud, but rather on data from other companies in
    previous years and different economic conditions. More
    importantly, it was based on cases in which there had been
    disclosure of accounting irregularities to the market, despite
    the fact that Craig’s accounting irregularities were never dis-
    closed while its stock was still publicly traded. As a result,
    because the method did not properly establish that Berger’s
    sentence was based only on “ ‘all harm that resulted from the
    acts or omissions’ of the defendant,” Hicks, 
    217 F.3d at 1048
    (quoting U.S.S.G. § 1B1.3(a)(3) (1995)), it was an abuse of dis-
    cretion.12
    [8] We therefore remand to the district court to redeter-
    mine, based on the principles described herein, how much of
    the shareholders’ loss was actually caused by Berger’s fraud.
    While we do not dictate the exact method the district court
    must use, we note that whatever method is chosen should
    attempt to gauge the difference between Craig’s share price—
    as inflated through fraudulent representation—and what that
    price would have been absent the misrepresentation.
    12
    In concluding that the district court’s method was erroneous, we do
    not suggest that Berger’s fraud caused no loss to investors. The district
    court found that Craig’s spring 1997 stock value decline was “unrelated
    to Berger’s criminal conduct” because it resulted not from disclosure of
    fraud, but from disclosure of the company’s poor financial status. But that
    conclusion is valid only in the narrowest sense. While revelation of Ber-
    ger’s fraud to the public did not depreciate Craig’s stock value (as Craig
    was no longer publicly traded by that point), it appears that the stock value
    was overvalued, at least in part, because of the fraud. As a result, many
    investors were likely induced to buy Craig stock at its IPO price under the
    false pretenses created by Berger and his cohorts. Had Craig’s financial
    troubles not been masked by fraud during the IPO, then surely (assuming
    the IPO had happened at all) Craig’s stock price would already have been
    significantly lower in spring 1997, Craig’s earnings would not have
    required restatement, and the stock value would not have plummeted.

    II.    Standard of Proof in Finding Sentencing Facts
    Berger next argues that, in circumstances such as these, due
    process requires the district court to find the loss amount by
    clear and convincing evidence, rather than by a preponder-
    ance of the evidence.
    A.     Nature of Dispute
    Maintaining that preponderance of the evidence is the
    proper standard, the government first argues that Berger chal-
    lenged only the methodology of the district court’s determina-
    tion, which is a purely legal dispute. See, e.g., United States
    v. Hardy, 
    289 F.3d 608
    , 613 (9th Cir. 2002). The government
    asserts that where there is no factual dispute, but only a legal
    dispute, preponderance of the evidence is the appropriate
    standard of proof for the district court to use in determining
    facts relevant to sentencing. In support, the government cites
    United States v. Romero-Rendon, 
    198 F.3d 745
    , 748 (9th Cir.
    1999),13 withdrawn by 
    220 F.3d 1159
    , 1165 (9th Cir. 2000)).
    This argument fails for two reasons. First, contrary to the
    government’s characterization, Romero-Rendon declined to
    address the appropriate standard of proof; instead, the court
    held that the unchallenged pre-sentence report constituted
    clear and convincing evidence of the critical predicate fact.
    See 
    id. at 1165
    . Here, however, Berger vigorously challenged
    the loss calculations before the district court.
    Second, although the parties disputed the validity of the
    district court’s loss calculation, making such a calculation
    13
    The government cites only a withdrawn version of Romero-Rendon,
    
    198 F.3d at 748
    , withdrawn by 
    220 F.3d 1159
    . The government maintains
    that Romero-Rendon states that preponderance of the evidence is an ade-
    quate standard where the defendant did not challenge the accuracy of the
    sentencing report. The superceding version of our decision in that case,
    however, did not so hold.
    UNITED STATES v. BERGER               15635
    necessarily involved the district court’s determination of how
    much loss was suffered, an issue we have held to be one of
    fact. See, e.g., United States v. Garro, 
    517 F.3d 1163
    , 1167
    (9th Cir. 2008) (citing United States v. Lawrence, 
    189 F.3d 838
    , 844 (9th Cir. 1999)) (holding that “[a] calculation of the
    amount of loss is a factual finding”). Thus, by challenging the
    loss amount, Berger raised both a factual and legal dispute.
    We proceed to consider what standard of proof the district
    court should have employed in resolving the factual dispute.
    We review the issue de novo because it, like the question
    regarding calculation method, is a question of law.
    B.   Standard of Proof for Finding Sentence-Enhancing
    Facts
    [9] A district court typically uses a preponderance of the
    evidence standard when finding facts pertinent to sentencing.
    United States v. Armstead, 
    552 F.3d 769
    , 776 (9th Cir. 2008)
    (citing United States v. Moreland, 
    509 F.3d 1201
    , 1220 (9th
    Cir. 2007)). In United States v. Restrepo, however, we con-
    cluded that, “when a sentencing factor has an extremely dis-
    proportionate effect on the sentence relative to the offense of
    conviction,” due process may require a district court to apply
    a heightened standard. 
    946 F.2d 654
    , 659-60 (9th Cir. 1991)
    (en banc) (emphasis added) (citing McMillan v. Pennsylvania,
    
    477 U.S. 79
    , 87-91 (1986), for the proposition that dispropor-
    tionate effect may require the application of the heightened
    standard but concluding that such an effect was not relevant
    in that case).
    Since Restrepo, we have not been a model of clarity in
    deciding what analytical framework to employ when deter-
    mining whether a disproportionate effect on sentencing may
    require the application of a heightened standard of proof.
    Some of our cases have explicitly stated that where the sen-
    tencing enhancements are based on charged conduct, i.e., the
    “offense of conviction,” employing a preponderance of the
    evidence standard does not implicate Restrepo’s due process
    15636               UNITED STATES v. BERGER
    concerns. See, e.g., United States v. Harrison-Philpot, 
    978 F.2d 1520
    , 1524 (9th Cir. 1992). We have also held that there
    is no “bright-line rule for the disproportionate impact test,”
    and instead look to the “ ‘totality of the circumstances,’ with-
    out considering any one factor as dispositive.” See, e.g.,
    United States v. Jordan, 
    256 F.3d 922
    , 928 (9th Cir. 2001)
    (citing United States v. Valensia, 
    222 F.3d 1173
    , 1182 (9th
    Cir. 2000), cert. granted, judgment vacated, and remanded
    by, 
    532 U.S. 901
     (2001) (reversing and remanding on other
    grounds)). We have followed the “totality of the circum-
    stances” approach even where the enhancement was based on
    the “offense of conviction.” Johansson, 
    249 F.3d at 853-58
    .
    Berger argues that our case law is irreconcilable, or prem-
    ised on an indefensible distinction between an enhancement
    based on the “offense of conviction” and one based on “un-
    charged” or “acquitted” conduct. He asserts that we have not
    always been diligent in maintaining this distinction, or even
    if we have, there is no basis for holding that facts relating to
    uncharged or acquitted conduct are subject to a heightened
    standard of proof, while facts relating to the offense of con-
    viction are not.
    [10] We decline Berger’s invitation to decide this case on
    such broad grounds, because a number of our cases squarely
    address the factual situation presented here. Those cases
    involve a defendant’s fraudulent conduct where sentencing
    enhancements for financial loss are based on the extent of the
    fraud conspiracy. They hold that facts underlying the disputed
    enhancements need only be found by a preponderance of the
    evidence. United States v. Riley, 
    335 F.3d 919
    , 926-27 (9th
    Cir. 2003); Armstead, 
    552 F.3d at 777-78
    ; Garro, 
    517 F.3d at 1168-69
    .
    In Riley, the defendant pled guilty to one count of conspir-
    acy to produce fictitious obligations, one count of possession
    of fictitious obligations, and one count of identification fraud.
    
    335 F.3d at 923
    . At sentencing, the district court applied a
    UNITED STATES v. BERGER                     15637
    nine-level enhancement to the defendant’s sentence under
    § 2F1.1(b)(1)(J), for a financial loss greater than $350,000 but
    less than or equal to $500,000. Id. We held that because this
    enhancement was “based entirely on the extent of the conspir-
    acy to which Riley pled guilty,” it was properly determined
    based on a preponderance of the evidence. Id. at 926-27.
    In Armstead, a jury convicted the defendant of nine counts
    of bank fraud and one count of conspiracy to commit bank
    fraud. 
    552 F.3d at 774
    . The district court applied a fourteen-
    level enhancement for the amount of loss under
    § 2B1.1(b)(1). Id. at 775-76. The defendant disputed
    $173,576.88 of the total loss, which represented the difference
    between a twelve-level and a fourteen-level increase. Id. at
    777 n.6. We held that the district court did not need to employ
    a clear and convincing standard of proof to the two-level
    enhancement because the loss amount was attributable to the
    extent of the conspiracy. Id. at 777-78.
    Finally, in Garro, the defendant was convicted of eight
    counts of wire fraud, eleven counts of money laundering, and
    one count of tax evasion. 
    517 F.3d at 1165
    . The district court
    found that the amount of loss in the defendant’s fraudulent
    scheme exceeded $20 million, resulting in a sixteen-level sen-
    tencing enhancement. 
    Id. at 1167
    . Again, citing Riley, we held
    that the district court’s enhancement was based on conduct for
    which the defendant had been charged and convicted, and
    therefore the district court properly used a preponderance of
    the evidence standard of proof. 
    Id. at 1169
    .
    [11] Here, like in Riley, Armstead, and Garro, the enhance-
    ment under U.S.S.G. § 2F1.1 is based entirely on the extent
    of the fraud conspiracy for which Berger was convicted. See
    Riley, 
    335 F.3d at 926
    .14 Applying the holdings of Riley, Arm-
    14
    Berger’s reliance on Staten and Zolp is misplaced. Neither Staten nor
    Zolp focused on the standard of proof, and therefore neither calls into
    question our holdings in Riley, Armstead, or Garro. See United States v.
    15638                  UNITED STATES v. BERGER
    stead, and Garro to this case, we conclude that the district
    court did not err in using a preponderance of the evidence
    standard to determine the amount of loss for purposes of
    § 2F1.1.
    CONCLUSION
    For the reasons described, we vacate Berger’s sentence,
    affirm the district court’s ruling on the applicable standard of
    proof in finding sentence-enhancing facts in this context, and
    remand to the district court for resentencing before a new dis-
    trict judge15 consistent with the standards articulated in this
    opinion.

    a statement is “merely a prelude to another legal issue that commands the

    considered the viability of the “disproportionate impact” rule following
    the Supreme Court’s decision in Booker, Staten, 466 F.3d at 717-20, and
    Zolp addressed a district court’s factual finding that the stock at issue was
    worthless after the defendant’s fraud came to light, Zolp,

    applies “ ‘where an extremely disproportionate sentence results from the
    application of an enhancement,’ ” 
    Id. at 718
     (quoting Staten, 466 F.3d at

    mand[ed] the panel’s full attention,” Johnson, 
    256 F.3d at 915
    . To the con-
    trary, Riley specifically held that the preponderance standard applied to a
    sentencing enhancement for the amount of loss under U.S.S.G. § 2F1.1.
