    Before KING, BENAVIDES, and DENNIS, Circuit Judges
    BENAVIDES, Circuit Judge:
    Defendants-Appellants James Patrick Phillips, Wesley C. Walton, and
    James Brooks (collectively, the “Defendants-Appellants”) appeal their conviction
    of and sentencing for false reporting of natural gas trades in violation of the
    Commodities Exchange Act and the federal wire fraud statute. We AFFIRM.
    FACTUAL AND PROCEDURAL BACKGROUND
    The Defendants-Appellants are former employees of El Paso Merchant
    Energy Corporation (“EPME”), a subsidiary of the El Paso Corporation (“El
    Paso”). The government alleges that the Defendants-Appellants violated the
    Commodities Exchange Act (“CEA”) and the wire fraud statute by sending false
    information about natural gas prices to trade magazines that report natural gas
    Case: 09-20871       Document: 00511861304          Page: 2    Date Filed: 05/18/2012

    prices in indexes, in an effort to affect and manipulate those indexes, which, in
    turn, would affect the market for natural gas futures and benefit the company’s
    financial positions.
    Some background on the natural gas industry is necessary for
    understanding this case. Natural gas is transported throughout North America
    via a network of pipelines. The gas transportation network is centered around
    “hubs,” which are geographical locations where major pipeline systems interlink.
    These hubs act as separate markets, at which supply and demand dictate prices
    that may differ between the hubs.
    Gas trades are divided into different types. Most basically, physical gas
    is traded, whereby one company agrees to purchase a quantity of gas to be
    physically delivered to a particular location. In addition to the sale of physical
    gas, financial trades are made based on gas prices. One particular financial
    trade, a gas contract for future delivery, is traded on the New York Mercantile
    Exchange (“NYMEX”). NYMEX contracts are based on the price of gas trading
    at Henry Hub, Louisiana.             Other financial trades, termed “swaps,” are
    transactions where two traders agree to buy a volume of gas from each other at
    the same time, but at different prices. In one common format, called a “basis”
    trade, one party agrees to pay a first-of-the-month index price and the
    counterparty agrees to pay based on the last day NYMEX settle. Another
    common financial transaction is an exchange for physical futures (“EFP”), which
    is a swap with one end priced off the NYMEX futures market and the other
    prices off an index plus or minus a differential.1 Financial trades generally do
    not result in the transfer of physical gas, but are resolved financially.
    1
    In these various futures transactions, the parties discuss financial traders holding
    “short” or “long” positions. In a “short” position, a trader benefits from a lower index price,
    and in a “long” position, the trader benefits from a higher index price.

    The market index prices for physical gas are most prominently published
    in two privately owned newsletters: Inside FERC Gas Market Report (“Inside
    FERC”) and Natural Gas Intelligence (“NGI”). Both of these publications publish
    the natural gas price marketing indicators at the major pipeline hubs and
    market centers in the United States, and it is undisputed that both publications
    are highly influential to market price for physical gas. The indexes also are used
    to determine royalties and public gas contracts, among other things. The
    publications gather pricing information about the various markets and pipeline
    hubs by requesting data about physical gas transactions from natural gas
    traders. After receiving data from the gas traders, and taking a variety of other
    factors into account, the publications release indexes that purport to represent
    the price of natural gas at different delivery points. In requesting data, Inside
    FERC and NGI requested that traders report fixed-price, baseload deals
    negotiated during bidweek, and it also instructed that basis or EFP trades not
    be reported.2
    The Defendants-Appellants were all employees at EPME. EPME traded
    in both physical and financial transactions of the sort previously mentioned. In
    2000, Defendant-Appellant Brooks was EPME’s Senior Vice President for Risk
    Management, and he was responsible for overseeing physical traders. In 2001,
    Brooks became the Managing Director for Natural Gas, and he oversaw both
    physical and basis traders. At the time, EPME was divided into various trading
    “desks,” which were then split between physical gas trading and finance trading.
    The desks were based on pipeline network regions. During the time in question,
    Defendant-Appellant Phillips was a senior physical trader and was manager of
    the Texas Desk at EPME. Defendant-Appellant Walton was a basis trader on
    the financial side for both the Texas Desk and the Gulf Coast Region of the

    As will be explained, the parties dispute the extent to which these terms have
    accepted meanings in the natural gas industry.

    Northeast Desk. As a market participant, Inside FERC and NGI would request
    physical trade information from EPME. EPME would report the information to
    the trade publications via spreadsheets sent by the physical traders responsible
    for each of EPME’s desks.
    From summer 2002 to fall 2002, El Paso received inquires from various
    federal agencies and a United States Attorney’s Office grand jury subpoena
    seeking information on the reports EPME sent to the trade publications.3
    Around that time, El Paso hired Haynes & Boone, a law firm, to conduct an
    internal investigation into allegations that El Paso employees had submitted
    false trades to trade publications. Defendants-Appellants Brooks, Walton, and
    Phillips were interviewed as part of that investigation, and each employee was
    subsequently terminated.          Nonetheless, at least at the beginning of this
    investigation, El Paso paid the legal fees for both Walton and Brooks.
    Starting in March 2003, an Assistant U.S. Attorney began a course of
    correspondence with El Paso’s legal counsel about El Paso’s payment of legal fees
    for former employees. El Paso informed the Assistant U.S. Attorney about the
    company by-laws, according to which EPME was required to indemnify any
    employee for legal fees if the employee was found not to have engaged in wrong-
    doing, but EPME was left with discretion about whether to advance payment of
    legal fees prior to such determination.4 El Paso stated that, based in part on
    3
    Prior to the United States Attorney’s investigation, in 2000, the California Public
    Utilities Commission started an investigation of El Paso, during which Southern California
    Edison also requested documents related to EPME’s reporting. Moreover, at about the time
    of the United States Attorney subpoena, El Paso received similar requests for information
    from the Commodities Futures Trading Commission and the Federal Energy Regulatory
    Commission.
    4
    El Paso and EPME had slightly different policies. El Paso’s by-laws required it to
    both indemnify and to advance legal fees for any of its employees. El Paso would then have
    the right to seek a refund of payments if the employee was found to have engaged in wrong-
    doing. EPME was only required to indemnify its employees, however, and the defendants here
    were all EPME employees.

    “the limited results of the Haynes & Boone interviews,” it had decided not to
    advance legal fees for Brooks, but that it was inclined to advance Walton’s legal
    fees.       El Paso stressed, however, that it would consider the employee’s
    cooperation with the federal investigation in deciding whether to continue
    advancing legal fees. After additional correspondence regarding Delaware law
    and its application to El Paso’s indemnification policy, the government, in
    response to El Paso’s request for the identities of any individual who was not
    cooperating, identified Walton, as well as four other employees, who are not
    defendants here, as non-cooperating employees. Sometime thereafter, El Paso
    terminated Walton’s legal fees, but it did not inform the government.
    Defendant-Appellant Phillips, who had not been discussed in the
    correspondence, subsequently requested indemnification. On August 12, 2004,
    El Paso declined Phillips’s request, noting that indemnification was made only
    after an ultimate determination of the legal proceedings, and that it would not
    advance his legal fees. El Paso also noted that it was not obliged to advance fees,
    and that EPME was cooperating with the government and so it would not
    advance legal fees to “potential subjects or targets of their investigations.”5
    On September 25, 2006, the government filed a second superseding
    indictment, charging the Defendants-Appellants with forty-nine counts:
    specifically, twenty-four counts of false reporting in violation of the CEA, 
    7 U.S.C. § 13
    (a)(2), twenty-four counts of wire fraud in violation of 
    18 U.S.C. § 1343
    , and one count of conspiracy to commit false reporting and wire fraud in
    violation of 
    18 U.S.C. § 371
    . The government alleged that the Defendants-
    Appellants were involved in a conspiracy, lasting from about April 2000 through
    5
    Phillips subsequently filed a civil suit to force EPME to advance his legal fees, in
    which he sought discovery. See Phillips v. El Paso Corp., no. 2005-00645 (Texas Dist. Ct. Jan.
    5, 2005). The government filed a successful motion to stay that civil suit, pending the criminal
    investigation.

    May 2002, whereby the Defendants-Appellants reported false information
    related to natural gas prices to Inside FERC and NGI to manipulate the index
    prices reported in those magazines. Specifically, the government alleged that
    Defendant-Appellant Brooks would direct the physical gas traders at EPME to
    report false data to the publications, such as trades that did not occur, false
    prices, or false gas volumes, in a manner that would benefit EPME’s financial
    positions.   Defendant-Appellant Walton, a basis trader on the Texas and
    Northeast Desks, would allegedly tell the physical traders his financial positions
    for the upcoming month, such as whether he wanted the index price of gas to
    increase or decrease in certain areas, so the physical traders could report data
    manipulating the published indexes in his favor. The second superseding
    indictment also alleged that Defendant-Appellant Phillips and the other physical
    gas traders sent fictitious information and reports to Inside FERC and NGI. The
    government alleged that twenty-four misleading reports were transmitted to
    these publications, either personally by the Defendants-Appellants or based on
    their instructions.6
    The trial lasted from December 4, 2007 to February 7, 2008. During the
    trial, the government submitted over 1,000 exhibits, including the bidweek
    surveys sent to Inside FERC and NGI, internal worksheet versions of those
    surveys, internal EPME emails, EPME trade tickets recording physical and
    basis deals, summaries of basis positions, and hundreds of taped telephone calls.
    During trial, the jury heard testimony from fourteen government witnesses,
    including Matthew O’Loughlin, an expert, and five defense witnesses, including
    Defendant-Appellant Brooks.
    The government’s two primary witnesses were physical traders Dallas
    Dean and Sharon O’Toole. Dean was a physical trader on the Northeast Desk
    6
    A number of other members of the alleged conspiracy have already pled guilty to
    charges of false reporting, wire fraud, or conspiracy.

    No. 09-20871
    and O’Toole was a physical trader on the Texas Desk. Both testified about the
    conspiracy and stated that Defendant-Appellant Brooks instructed them to
    submit false data to Inside FERC based on information given to them by
    Defendant-Appellant Walton. O’Toole also testified about Defendant-Appellant
    Phillips’s involvement in the conspiracy. The government also admitted a large
    number of incriminating emails between the various traders—often between
    Phillips and other physical traders—about the content of the reports sent to
    Inside FERC and NGI or requesting information from basis traders about their
    financial positions. Similarly, the government played recordings of telephone
    calls, many recorded on Walton’s line. In some of these conversations, Walton
    discussed price targets for certain trading regions, the submission of reports that
    would or had affected published indexes, and whether certain reported trades
    were too low to be credible. He also thanked the physical traders when the
    published index prices were favorable to his financial positions.
    In one particularly important email chain, various EPME employees,
    including Brooks, Phillips, and Walton, discussed the reports sent to the
    publications. Starting this chain, Brooks emailed the physical and financial
    traders on October 23, 2000, writing:
    There has [sic] been several discussions on how IF [Inside FERC]
    price should be reported in the month of November. Most of you are
    aware that we reported only verifiable fixed price transactions to IF
    for October. It is the opinion of some, that the reason for doing so
    made no difference, and only eliminated us as an active price setting
    participant. In an effort to get everyone’s opinion on this, reply as
    to the following: 1. Report according to our book bias (as in the
    past). 2. Report verifiable fixed price trades only.
    In response, various traders, including Walton and Phillips, chose the first
    option. Several other traders discussed the options, emailing with Brooks and
    discussing how Inside FERC had a standardized format for reporting data, but
    that the “integrity of the data . . . is not verified.” Another trader replied that
    7
    Case: 09-20871   Document: 00511861304     Page: 8   Date Filed: 05/18/2012
    No. 09-20871
    they should “avoid discussing this is on e-mail” due to ongoing investigations,
    and O’Toole replied, “GOOD point!”
    Also testifying for the government was Ronald Clay Sanders, an employee
    at EPME, who worked as the manager of the risk operations group during the
    time of the alleged conspiracy. Sanders testified whether the trades reported to
    Inside FERC or NGI by the physical traders were real and whether they
    matched any trades in the EPME electronic database. Overall, Sanders testified
    that only 3.6% of the 6,213 trades reported to Inside FERC and NGI during the
    course of the conspiracy matched actual trades, and that if the trades reported
    by the West Desk are excluded—which allegedly stopped participating in the
    conspiracy in fall 2002—only 1.9% of the 5,687 trades match actual trades.
    Finally, the government presented O’Loughlin, an expert who testified about the
    effect of EPME’s false reports on the published indexes at Inside FERC and NGI.
    The primary defense witness was Defendant-Appellant Brooks. In part,
    Brooks testified about the incriminating October 2000 email chain where the
    traders discuss reporting based on “book bias.” Brooks testified that “book bias”
    did not mean that the physical traders would submit numbers favoring the basis
    traders’ positions; rather, Brooks stated that the term meant that EPME would
    report data to the publications based on their perception of where gas was
    actually trading.
    A potential defense witness, Don Guilbault, invoked his Fifth Amendment
    privilege against self-incrimination on the day he was scheduled to testify.
    Guilbault was a physical trader at EPME and he had admitted to submitting
    false reports to Inside FERC and NGI. According to the Defendants-Appellants,
    however, Guilbault would have testified that Walton did not provide him with
    basis positions to shape his reports. Although Guilbault pled guilty prior to the
    Defendant-Appellants’ trial, he was still awaiting sentencing at the time of the
    current trial to ensure cooperation. The Defendants-Appellants moved to compel
    8

    No. 09-20871
    testimony; after a hearing, the district court denied the motion, finding no
    government misconduct and a valid purpose for the invocation of privilege.
    After closing arguments, the jury deliberated for three days. The jury sent
    several notes during deliberations, one of which asked a question about the
    phrase “ignorance of the law is no excuse.” Ultimately, the jury found: all
    Defendants-Appellants guilty of the conspiracy count; Phillips guilty of false
    reporting and wire fraud on counts 5, 9–10, 14, 19–21, 23–25, 29, 33–34, 38,
    43–45, 47–49, and not guilty on all other charged counts; Walton guilty of false
    reporting and wire fraud on counts 3–5, 9–10, 19–24, 27–29, 33–34, 43–48, and
    not guilty on all other charged counts; and Brooks guilty on counts 2–5, 8–29,
    32–49, and not guilty on all other charged counts.
    On December 17, 2009, the district court sentenced the Defendants-
    Appellants. The district court calculated, for Phillips and Walton, that the
    proper offense level was thirty-three (with criminal history category 1), with a
    recommended sentencing range of 135 to 168 months. For Brooks, the district
    court calculated that the offense level was thirty-five (with a criminal history
    category 1), with a recommended sentencing range of 168 to 210 months. The
    district court sentenced Phillips and Walton to 135 months of imprisonment and
    sentenced Brooks to 168 months of imprisonment.
    The Defendants-Appellants filed a timely notice of appeal, and they now
    assert ten separate grounds for error. They argue that the indictment must be
    dismissed, and that their convictions and sentences must also be reversed.
    ANALYSIS
    A. Government Interference with Payment of Legal Fees
    The Defendants-Appellants first argue that the government pressured
    EPME to cut off its payment of legal fees for their attorneys, violating their Fifth
    and Sixth Amendment rights, and consequently, requiring dismissal of the
    indictment against them, relying on 2003 correspondence between the Assistant
    9
    Case: 09-20871      Document: 00511861304   Page: 10    Date Filed: 05/18/2012
    No. 09-20871
    U.S. Attorney and El Paso’s legal counsel. The district court found no such
    pressure by the government, and the Defendants-Appellants do not show clear
    error in that determination.
    We review a district court’s denial of a motion to dismiss an indictment de
    novo. United States v. McNealy, 
    625 F.3d 858
    , 868 (5th Cir. 2010). We review
    the district court’s underlying factual findings for clear error. 
    Id.
     “Under the
    clear error standard, we defer to the findings of the district court unless we are
    left with a definite and firm conviction that a mistake has been committed.”
    United States v. Avants, 
    367 F.3d 433
    , 441 (5th Cir. 2004) (citation and internal
    quotation omitted).
    The record creates no “firm conviction” that the district court erred in
    finding the government did not coerce El Paso into deciding not to advance the
    Defendants-Appellants’ legal fees. While the correspondence shows El Paso
    possessed an intense desire to be seen as cooperative by the government, the
    government never demanded or suggested to El Paso that it cease paying the
    legal fees of the Defendants-Appellants. Indeed, rather than create a “firm
    conviction” that El Paso was coerced into not paying the Defendants-Appellants’
    attorney fees, the correspondence shows El Paso, through EPME, exercised its
    own discretion whether to pay the Defendants-Appellants’ legal fees. The
    correspondence shows that EPME had the discretion, under its by-laws, not to
    advance legal fees to its employees. Further, as to Brooks, the correspondence
    shows El Paso had exercised that discretion prior to the government’s
    correspondence due to the company’s conclusion that he was involved in wrong-
    doing.
    Nor do Defendants-Appellants fair better in relying on the 2003 Justice
    Department Memorandum, “Principles of Federal Prosecution of Business
    10
    Case: 09-20871       Document: 00511861304      Page: 11     Date Filed: 05/18/2012
    No. 09-20871
    Organizations,” also known as the “Thompson Memorandum.”7 That
    memorandum provided guidance on how the government should decide whether
    a corporate entity is cooperating with an investigation, and it suggested that
    investigators consider whether a corporation was advancing legal fees to
    culpable agents. Admittedly, that memorandum has been subject to criticism,
    and the Department of Justice has subsequently revised its policies.
    Nevertheless, the mere existence of the memorandum could not have compelled
    El Paso.
    This case is distinguishable from the facts that the Second Circuit
    confronted in United States v. Stein, 
    541 F.3d 130
     (2d Cir. 2008). There, the
    district court found that the government had “forced” KPMG to cease paying
    legal fees on behalf of the defendants, the payment of which had been KPMG’s
    long-standing policy, based on threats from the government and the
    government’s involvement in crafting internal KPMG memos dissuading
    employees from obtaining counsel. 
    Id.
     at 147–50. The district court’s factual
    findings bound the Second Circuit, and on such findings, the Second Circuit held
    KPMG’s actions were state actions that violated the defendants’ right to counsel
    of their choice. 
    Id.
    Here, as noted above, no such factual findings were made, and reasonably
    so. Whereas in Stein, where the government specifically threatened to take into
    account KPMG’s payment of legal fees, referring to the Thompson Memorandum,
    the correspondence here does not refer to that memorandum and it includes no
    threat to indict El Paso if it continued to pay fees. Moreover, the government did
    not meddle in El Paso’s internal discussion with employees in an attempt to
    dissuade the retention of counsel. Lastly, whereas KPMG’s long-standing policy

    of paying legal fees demonstrated that the fees would have been paid but for the
    government’s actions, EPME’s policy was discretionary, and had been
    independently exercised to not advance legal fees to Brooks.
    Accordingly, the Defendants-Appellants fail to show clear error in the
    district court’s factual findings, and under those facts, we find that denial of the
    motion to dismiss the indictment was proper.
    B. Applicability and Constitutionality of CEA
    The Defendants-Appellants raise a number of challenges to the
    applicability and constitutionality of the CEA. First, they argue that 
    7 U.S.C. § 13
    (a)(2)’s reference to “false . . . reports” does not cover the false reports they
    sent to industry newsletters. Second, they argue that trades of physical natural
    gas are exempted from the CEA and/or do not meet the Act’s definition of
    “commodity.” Third, the Defendants-Appellants argue that various terms in
    § 13(a)(2) are vague, and thus the CEA is unconstitutionally vague as applied to
    them. Fourth, they argue that the CEA is overbroad. While the Defendant-
    Appellants’ arguments are sweeping, they are, ultimately, unavailing.
    1.     “Report”
    The Defendants-Appellants first argue that their communications with
    Inside FERC and NGI do not qualify as “reports” under §13(a)(2). They state
    that other portions of the CEA, as well as the CFTC’s regulations promulgated
    thereunder, distinguish between “statements” and “reports,” and generally use
    “report” to refer to “a formal record or document the Commission requires
    regulated futures professionals or traders to file, maintain or provide to the
    Commission or costumers.”
    The CEA states that it shall be unlawful for:
    [a]ny person . . . knowingly to deliver or cause to be delivered for
    transmission through the mails or interstate commerce by
    telegraph, telephone, wireless, or other means of communication
    false or misleading or knowingly inaccurate reports concerning . . .
    12
    Case: 09-20871        Document: 00511861304          Page: 13     Date Filed: 05/18/2012
    No. 09-20871
    market information or conditions that affect or tend to affect the
    price of any commodity of interstate commerce . . . .
    
    7 U.S.C. § 13
    (a)(2). The term “reports” is not defined in the CEA or CFTC
    regulations. See 7 U.S.C. § 1a; 
    17 C.F.R. § 1.3
    . Neither the Supreme Court nor
    any circuit court has considered the definition.8 Consequently, the applicability
    of the term “reports” appears to be an issue of first impression.
    “In construing the United States Code our task must begin with the words
    provided by Congress and the plain meaning of those words.” United States v.
    Valencia, 
    394 F.3d 352
    , 355 (5th Cir. 2004). Thus, we begin with the plain
    meaning of “report[],” which the dictionary defines as any statement of fact, or
    at least a detailed statement of fact. See Merriam-Webster, report, available at
    http://www.merriam-webster.com/dictionary/report (defining report as “a usually
    detailed account or statement); Oxford English Dictionary, report, available at
    http://www.oed.com/search?searchType=dictionary&q=report (defining report as
    “[i]nformation provided or conveyed, and related senses,” “[a]n account of a
    situation, event, etc., brought by one person to another . . . , a notification of
    something observed,” “[a] descriptive account or statement”); see also CBC, Inc.
    v. Bd. of Governors of Federal Reserve Sys., 
    855 F.2d 688
    , 690–91 (10th Cir.
    1988) (applying dictionary definition of “report” to interpret word in Bank
    Holding Act).9 The Defendants-Appellants’ statements to Inside FERC and NGI
    would satisfy such a definition. They were not expressions of opinion, or casual
    communications, but were lengthy documents outlining detailed information
    8
    A district court has considered the definition of “report” and found it covers electronic
    communications such as the Defendants-Appellants’. See CFTC v. Atha, 
    420 F. Supp. 2d 1373
    ,
    1380–81 (N.D. Ga. 2006) (finding § 13(a)(2) false reporting provision applies to false trade
    reports sent electronically to Inside FERC).

    The Defendants-Appellants provide the court with no reason to believe “report,” first
    included in the Grain Futures Act of 1922, had a meaning other than that used today. See
    Grain Futures Act, 42 State 998, 1003 (1922).

    Case: 09-20871     Document: 00511861304      Page: 14    Date Filed: 05/18/2012
    No. 09-20871
    about natural gas trades, sent to established industry publications with the
    intent to inform those publications about the state of the natural gas markets.
    The Defendants-Appellants argue that “reports,” when used in the CEA,
    refers only to formal reports required under the statute to be submitted by
    traders to the CFTC or to customers, and that other portions of the CEA
    differentiate between “reports” and mere “statements.” While it is true that
    various parts of the CEA specify reports that are to be kept and submitted, such
    fact cuts against the Defendants-Appellants. Where the CEA discusses reports
    to be sent to the CFTC or to customers, the CEA specifies the kind of report. See
    7 U.S.C. § 6g (providing “[e]very person registered hereunder . . . shall make
    such reports as are required by the Commission . . .” (emphasis added)); 7 U.S.C.
    § 6i(2) (providing certain trades unlawful “unless such person files . . . with . . .
    the Commission such reports regarding any transaction . . . as the Commission
    may by rule . . . require” (emphasis added)); 
    17 C.F.R. § 16.00
     (providing “[e]ach
    reporting market shall submit to the commission . . . a report . . . showing”
    specified information); 
    17 C.F.R. § 17.00
     (providing “[e]ach futures commission
    merchant . . . shall submit a report to the Commission . . .”; requiring report to
    provide specified information). Such specifics would be unnecessary if every use
    of “report” implied the same type of report. The fact that the CEA specifies the
    kind of report when discussing reports to be made to the CFTC or to customers
    implies that when the CEA uses “report,” without such limits, it does so in a
    more general fashion.
    Indeed, reading § 13(a)(2) in the manner suggested by Defendants-
    Appellants would render other sections of the CEA superfluous. The next two
    subsections of the CEA make it unlawful for “[a]ny person knowingly to make
    . . . any statement in any application, report, or document required to be filed
    under this chapter . . . which statement was false or misleading with respect to
    a material fact,” and for “[a]ny person willfully to falsify . . . a material fact,
    14
    Case: 09-20871     Document: 00511861304       Page: 15     Date Filed: 05/18/2012
    No. 09-20871
    make any false . . . statements or representations . . . to a registered entity,
    board of trade, of futures associations . . . .” 
    7 U.S.C. §§ 13
    (a)(3), (4) (emphasis
    added). Similarly, 7 U.S.C. § 6b(a)(2) renders it unlawful for “any person, in or
    in connection with any order to make . . . any contract of sale of any commodity
    for future delivery . . . , (B) willfully to make or cause to be made to the other
    person any false report or statement or willfully to enter or cause to be entered
    for the other person any false record.” If § 13(a)(2) was intended to cover only
    false reports sent to the CFTC or to customers, these other sections would be
    superfluous.
    Moreover, if § 13(a)(2) concerned only false reports submitted to the CFTC,
    or false reports submitted from traders to customers, there would be no need to
    limit the provision to communications “in interstate commerce,” and that “affect
    or tend to affect the price of any commodity.” See 
    7 U.S.C. § 13
    (a)(2). These
    jurisdictional “hooks” would not be needed for Congress to regulate false
    communications to a government agency, or false communications by federally
    registered traders. See M’Culloch v. Maryland, 17 U.S. (4 Wheat.) 316, 417 (1819). The
    fact is apparent when one looks at the CEA’s provisions that specifically deal
    with false reports to the CEA or customers. Those sections are not limited to
    communications in interstate commerce or to those that affect commodity prices.
    Instead, they render all false statements to the CFTC or customers by registered
    traders unlawful. See 7 U.S.C. §§ 6b(a)(2)(B), 13(a)(3)–(4).
    Further, the language in § 13(a)(2) indicates that covered “reports” include
    more than formal communications to the CFTC or customers. As the Northern
    District of Georgia pointed out, § 13(a)(2) covers reports communicated “through
    the mails or interstate commere by telegraph, telephone, wireless or other means
    of communication.” See CFTC v. Atha, 
    420 F. Supp. 2d 1373
    , 1380–81 (N.D. Ga.
    2006). As the section clearly contemplates reports sent by telephone, it is
    unlikely it is intended to cover only the official reports.
    15
    Case: 09-20871      Document: 00511861304     Page: 16    Date Filed: 05/18/2012
    No. 09-20871
    Finally, the CFTC has consistently interpreted § 13(a)(2) to apply to trade
    reports sent to Insider FERC and/or NGI, like those sent by the Defendants-
    Appellants. Although not promulgated in notice-and-comment rulemaking, the
    CFTC has sued various defendants for behavior identical or similar to that at
    issue here. See CFTC v. Dizona, 
    594 F.3d 408
    , 411–13 (5th Cir. 2010) (alleging
    defendants sent false reports to Inside FERC and NGI; affirming district court’s
    refusal to overturn jury verdict on false reporting because no evidence that
    reports were false); CFTC v. Reed, 
    481 F. Supp. 2d 1190
    , 1193 (D. Colo. 2007)
    (alleging defendants sent false trade reports to “industry reporting firm”); Atha,
    
    420 F. Supp. 2d at
    1377–78 (alleging defendants sent false reports to Insider
    FERC, NGI, and Gas Daily). The CFTC’s consistent interpretation is afforded
    at least some deference. See generally Skidmore v. Swift & Co., 
    323 U.S. 134
    (1944).
    Accordingly, we find that the Defendant-Appellants’ communications with
    Inside FERC and NGI qualified as “reports” under 
    7 U.S.C. § 13
    (a)(2).
    2.     Covered Commodities
    The Defendants-Appellants next argue that the CEA does not apply to
    their conduct, making two arguments. First, they argue that natural gas is an
    exempt commodity under the CEA, and thus, the types of contracts they
    allegedly falsely reported—natural gas contracts—are exempt. Second, they
    argue that because the CEA only regulates natural gas futures contracts, which
    are traded on NYMEX, any false reporting related to index prices at hubs other
    than Henry Hub are not covered by the CEA.              These arguments will be
    considered in turn.
    a. Exemptions
    In 1993, the CFTC issued a final rule which “exempt[ed] from all
    provisions of the [CEA], [except certain provisions to the extent they prohibit
    manipulation] . . . [c]ontracts for the purchase and sale of . . . natural gas, [and]
    16
    Case: 09-20871    Document: 00511861304       Page: 17   Date Filed: 05/18/2012
    No. 09-20871
    natural gas liquids.” See 
    58 Fed. Reg. 21,286
    , 21,294 (1993). Thereafter, 
    7 U.S.C. § 2
    (g)–(h) was amended in 2000, as part of the Commodity Futures
    Modernization Act, to exclude all trades between individual qualified
    participants that are not “executed or traded on” or “entered into on” a “trading
    facility,” which, defendants argue, covers the physical natural gas trades. The
    Defendants-Appellants contend that because natural gas is exempted under both
    the 1993 CFTC rule and the 2000 amendment to the CEA, their false reporting
    practices are also exempted from the CEA’s coverage.
    The Defendants-Appellants’ argument, however, has been uniformly
    rejected by the courts that have considered it—this Court included. In United
    States v. Futch, an unpublished decision, this Court found that the various
    exemptions only cover actual contracts for natural gas, and do not cover false
    reports about non-existent contracts. See 278 F. App’x 387, 392 (5th Cir. 2008).
    In reaching this holding, this Court stated that “§ 13(a)(2)’s false reporting
    offense . . . extends to ‘any commodity in interstate commerce’ and is not limited
    to futures contracts regulated by the CFTC . . . [;] ‘false reporting of market
    information concerning natural gas and attempted manipulation of natural gas
    price indices does not implicate an agreement, contract or transaction’ and thus
    does not come under the exceptions in 
    7 U.S.C. § 2
    (g)–(h).” See 
    id.
     (citations and
    quotations omitted).     As in Futch, the charges against the Defendants-
    Appellants do not arise from their execution of contracts for purchase of natural
    gas, or contracts entered into outside of a trading facility, but rather, for filing
    false reports about contracts that they claimed to have executed.
    This reading has been uniformly adopted by courts, and the Defendants-
    Appellants do not cite any contrary case law to support their argument. See,
    e.g., Reed, 
    481 F. Supp.2d at
    1197–98 (holding that false reporting not
    exempted); Atha, 
    420 F. Supp.2d at
    1379–80 (same); CFTC v. Bradley, 
    408 F. Supp. 2d 1214
    , 1218–19 (N.D. Okla. 2005) (same); United States v. Valencia, No.
    17
    Case: 09-20871       Document: 00511861304          Page: 18     Date Filed: 05/18/2012
    No. 09-20871
    Civ. A. H-03-024, 
    2003 WL 23174749
    , at *10 (S.D. Tex. Aug. 25, 2003) (same),
    rev’d on other grounds, 
    394 F.3d 352
     (5th Cir. 2004); see also CFTC v. Johnson,
    
    408 F. Supp. 2d 259
    , 266–67 (S.D. Tex. 2005) (not expressly addressing issue but
    finding that CEA covers nearly identical false reporting practices).10 Moreover,
    other decisions by this Court have implicitly found that the CEA covers false
    reports about natural gas markets, even if it would not cover the falsely reported
    contracts (if they existed). See Dizona, 
    594 F.3d at 418
     (dismissing false
    reporting count for lack of evidence, but assuming CEA covered similar false
    reporting of natural gas); Valencia, 
    394 F.3d at
    353–57 (assuming but not
    expressly deciding that the CEA covers false reporting of natural gas); see also
    58 Fed. Reg. at 21,291 (approving exemption of natural gas; noting conduct
    “otherwise subject to the Act would not be exempt for such activity, even if it
    were connected to their exempted . . . (Energy Contract) activity”). In sum,
    given that we agree with the previously cited decisions that squarely rejected the
    Defendants-Appellants’ argument, we hold that the exemptions in the CEA and
    the CFTC do not cover their reporting activities.
    b. “Commodity”
    The Defendants-Appellants next contend that the false reports they
    submitted did not concern a “commodity” subject to the CEA. They argue that
    only natural gas traded at Henry Hub is a commodity under the CEA because
    only natural gas traded at Henry Hub underlies the natural gas futures
    contracts traded on NYMEX. Consequently, because the government proved
    only that their false reports affected or could have affected the price of natural
    10
    Cf. United States v. Radley, 
    632 F.3d 177
    , 182–83 (5th Cir. 2011) (holding § 2(g)’s
    “contract, agreement, or transaction” not limited to legally enforceable agreements, but also
    covers “conducting business,” thus including, and exempting from CEA, defendants’ allegedly
    manipulative actions; distinguishing Futch, stating falsely reporting trades is not “conducting
    business”).
    18
    Case: 09-20871       Document: 00511861304         Page: 19     Date Filed: 05/18/2012
    No. 09-20871
    gas generally, and not at Henry Hub, the Defendants-Appellants argue their
    convictions must be vacated. We do not agree.
    The CEA defines “commodity” as “wheat, cotton, rice, corn, oats, barley,
    rye . . . , and all other goods and articles, except onions . . . , and all services,
    rights, and interests . . . in which contracts for future delivery are presently or
    in the future dealt with.” See 7 U.S.C. § 1a(4). Natural gas is plainly a “good”
    or “article.” The questions thus turns on whether it is a good “in which contracts
    for future delivery are presently or in the future dealt with.”
    As mentioned above, futures contracts for natural gas are traded on
    NYMEX, and those futures are derivative of natural gas traded at Henry Hub.
    Nonetheless, the record shows that natural gas may be moved from any location
    to Henry Hub through the national pipeline system. Thus, it would be peculiar
    that natural gas at another hub is not a commodity, but suddenly becomes a
    commodity solely on the basis that it passes through Henry Hub, and ceases to
    be a commodity once it moves onto some other locale. While the price of that
    commodity may fluctuate with its location, and the forces of supply and demand
    at that location, the actual nature of the “good” does not change.11
    Although, as discussed above, the Defendants-Appellants conduct did not
    fall within the regulatory exemption, the existence of that exemption bolsters
    our reading of the definition of “commodity.”            The CFTC exempted from the
    CEA’s coverage “[c]ontracts for the purchase or sale of . . . natural gas.” See 58
    11
    Indeed, it is at least open to question whether the CEA requires a commodity to be
    the subject of a currently existing futures market, or merely that it be such a good for which
    a futures market could come into being. The CEA defines, as a commodity, all “goods . . . in
    which contracts for future delivery are presently or in the future dealt with.” See § 1a(4).
    Assuming only natural gas at Henry Hub was a covered commodity, the Defendants-
    Appellants present no reason why gas at other hubs could never serve as the basis for other
    futures markets. See United States v. Reliant Energy Servs., Inc., 
    420 F. Supp. 2d 1043
    , 1062
    (N.D. Cal. 2006) (holding “criminal manipulation provision of § [13(a)(2)] is not limited to
    futures contracts”; “[r]ather, according to the plain meaning of the text, the criminal
    manipulation provision also applies to ‘any commodity in interstate commerce’”).
    19
    Case: 09-20871      Document: 00511861304         Page: 20    Date Filed: 05/18/2012
    No. 09-20871
    Fed. Reg. at 21,294. Such an exemption would be unnecessary if natural gas
    was not a commodity under the act.12
    Case law supports such a reading. Although no court has squarely
    confronted the question presented by the Defendants-Appellants, neither has
    any court suggested that natural gas at hubs other than Henry Hub is outside
    the purview of the CEA. See Futch, 278 F. App’x at 390 (stating “natural gas is
    a commodity under the Commodity Exchange Act”); Valencia, 394 F.3d at353
    (considering allegations defendant manipulated natural gas market, by
    reporting false trades, in violation of § 13(a)(2)); United States v. Radley, 
    659 F. Supp. 2d 803
    , 806 (S.D. Tex. 2009) (stating “natural gas” was “the commodity at
    issue in the case”); Reed, 
    481 F. Supp.2d at 1196
     (finding allegations “Defendant
    attempted to manipulate the price of natural gas, a commodity that travels in
    interstate commerce” covered by CEA); Atha, 
    420 F. Supp.2d at
    1377–78 (stating
    “[n]atural gas is a commodity”); Bradley, 
    408 F. Supp.2d at 1220
     (“It is
    undisputed that natural gas constitutes a ‘commodity’ under the CEA.”);
    Johnson, 
    408 F. Supp.2d at
    264–65 (finding allegations defendants falsely
    reported natural gas trades stated a claim under § 13(a)(2)).
    Hershey v. Energy Tranfers Partners, L.P., 
    610 F.3d 239
     (5th Cir. 2010),
    does not contradict this reading. In that case, the Court considered whether
    private plaintiffs had a cause of action based on allegations that the defendants
    were manipulating the price of natural gas at hubs other than Henry Hub. 
    Id.
    at 243–49. The private plaintiffs’ standing to sue was premised on their holding
    NYMEX futures contracts. 
    Id. at 240
    . The CEA, however, provides a right of
    action for holders of a futures contract for manipulation of that contract or “the
    price of the commodity underlying such contract.” See 
    7 U.S.C. § 25
    (a)(1)(D).
    Consequently, as the plaintiffs had not alleged manipulation of the Henry Hub
    12
    The CFTC gave no indication that it believed the exemption covered only natural gas
    at Henry Hub.
    20
    Case: 09-20871    Document: 00511861304      Page: 21   Date Filed: 05/18/2012
    No. 09-20871
    natural gas price, which price underlay their security, they had no cause of
    action against manipulation of the price of natural gas which had no affect on
    their security. See Hershey, 610 F.3d at 241, 247 (stating “[t]he modifier
    ‘underlying’ has an important effect on ‘commodity’—the ‘underlying commodity’
    of a futures contract is a specific good, governed by the terms of the futures
    contract”; holding “the underlying commodity of a NYMEX natural gas futures
    contract is not natural gas wherever bought and sold, but the specific natural
    gas delivered at Henry Hub”). Hershey, however, never questioned whether
    natural gas was a commodity subject to § 13(a)(2).
    Accordingly, we find that natural gas, whether at Henry Hub or at some
    other location, is a “commodity” within the meaning of the CEA.
    3.    Vagueness
    The Defendants-Appellants next argue § 13(a)(2) is unconstitutionally
    vague because it fails to give fair notice that the CEA, an act whose primary
    purpose is to regulate futures and options, covers false reporting of physical
    trades. In particular, they argue that terms “report,” “false or misleading,”
    “market information,” “conditions that tend to affect the price of any commodity
    in interstate commerce,” and “price” are all vague.
    “It is a basic principal of due process that an enactment is void for
    vagueness if its prohibitions are not clearly defined.”      Grayned v. City of
    Rockford, 
    408 U.S. 104
    , 108 (1972). “[T]he void-for-vagueness doctrine requires
    that a penal statute define the criminal offense with sufficient definiteness that
    ordinary people can understand what conduct is prohibited and in a manner that
    does not encourage arbitrary and discriminatory enforcement.” Kolender v.
    Lawson, 
    461 U.S. 352
    , 357 (1983). Nonetheless, it is also “well established that
    vagueness challenges to statutes which do not involve First Amendment
    freedoms must be examined in light of the facts of the case at hand.” United
    States v. Mazurie, 
    419 U.S. 544
    , 550 (1975).
    21
    Case: 09-20871       Document: 00511861304          Page: 22      Date Filed: 05/18/2012
    No. 09-20871
    Here, the Defendants-Appellants do not argue that their speech is
    protected by the First Amendment. Indeed, this Circuit has held that
    “intentional or reckless falsehood, even political falsehood, enjoys no First
    Amendment protection[.]” Colson v. Grohman, 
    174 F.3d 498
    , 507 (5th Cir. 1999)
    (finding first amendment did not protect defamation and libel made with
    knowledge of or reckless disregard to falsity).13
    Consequently, the Defendants-Appellants’ vagueness challenge must be
    evaluated in light of the proven conduct. As discussed below, the evidence shows
    the Defendants-Appellants reported knowingly false trades to Inside FERC and
    NGI, that they did so with the intent that it affect those publications’ reported
    indexes, and with the intent that it would affect EPME’s financial positions, to
    their personal benefit. Simply put, it is incredulous to believe that a person of
    average intelligence could not understand the CEA as potentially applying to
    that type of conduct. See Futch, 278 F. App’x at 393–95 (holding CEA was not
    vague in application to false trade reports submitted to Inside FERC).
    In particular, “report,” as discussed above, clearly covers the Defendants-
    Appellants’ emails and faxes to the publications.                   Similarly, “false and
    misleading” has a clear and well defined meaning. “[M]arket information”
    clearly covers reports of quantity and price of trades. See id. at 393 (holding the
    term “‘market information’ is not vague because [defendant’s] false statements
    about time, place, price, and volume of . . . natural gas trades clearly qualified
    as ‘market information’ under almost any definition of the term”). Similarly, the
    term “price” is also clear.             See Merriam-Webster, price, available at
    13
    Moreover, as discussed below, the jury found each violation of the CEA was
    accompanied by an act of wire fraud, and fraud has long been recognized to be outside the
    protection of the First Amendment. See United States v. Stevens, 
    130 S.Ct. 1577
    , 1584 (2010)
    (finding “[f]rom 1791 to the present . . . , the First Amendment has permitted restrictions upon
    the content of speech,” including “fraud” (quotation and citations omitted)). Here, as discussed
    below, sufficient evidence was introduced that the Defendants-Appellants possessed a
    fraudulent intent.
    22

    No. 09-20871
    http://www.merriam-webster.com/dictionary/price (defining “price” as “the
    amount of money given or set as consideration for the sale of a specified thing”).
    Even if the Defendants-Appellants are correct that there are a number of prices
    in natural gas trading, each one of the referenced prices is a “price,” and thus
    manipulation of it would create a violation of § 13(a)(2). Finally, the term “affect
    or tend to affect” clearly covers a situation, such as the Defendants-Appellants’,
    where the false reports served as the basis for the industry publication’s price
    reports. See Futch, F. App’x at 394 (noting “even if the phrase ‘tends to affect’
    were found to be vague in some factual contexts, it is sufficiently clear to have
    put [defendant] on notice that providing false sales data to Inside FERC’s
    monthly reporting index survey violated the law”).
    Accordingly, the CEA is not unconstitutionally vague as applied to the
    Defendants-Appellants’ conduct.
    4.    Overbreadth
    The    Defendants-Appellants      also   challenge   the   CEA     as   being
    unconstitutionally overbroad. The Defendants-Appellants argue that the CEA,
    while directed at constitutionally unprotected speech, nevertheless covers
    constitutionally protected speech because it requires no mens rea proof with
    regard to the element that the speech “affect or tend to affect” commodity prices.
    A statute is overbroad if in “banning unprotected speech,” a “substantial
    amount of protected speech is prohibited or chilled in the process.” Ashcroft v.
    Free Speech Coalition, 
    535 U.S. 234
    , 237 (2002). Nevertheless, by its express
    language, the CEA only covers “knowingly . . . false or misleading or knowingly
    inaccurate” speech. Such speech is not constitutionally protected. See Colson
    v. Grohman, 
    174 F.3d 498
    , 507 (5th Cir. 1999). Accordingly, the CEA covers no
    constitutionally protected speech.

    No. 09-20871
    C. Jury Instructions
    The Defendants-Appellants next argue that the district court’s jury
    instructions were erroneous on several grounds. We review “preserved error in
    jury instructions under an abuse of discretion standard and ask whether the
    court’s charge, as a whole, is a correct statement of the law and whether it
    clearly instructs jurors as to the principles of the law applicable to the factual
    issues confronting them.” United States v. Kay, 
    513 F.3d 432
    , 446 (5th Cir. 2007)
    (quotation and footnote omitted). Under this standard, district courts “enjoy
    substantial latitude in formulating a jury charge.” United States v. Davis, 
    609 F.3d 663
    , 689 (5th Cir. 2010); see also United States v. Williams, 
    610 F.3d 271
    ,
    285 (5th Cir. 2010). Similarly, the district court is afforded “great discretion in
    responding to jury questions.” United States v. Wilcox, 
    631 F.3d 740
    , 752 (5th
    Cir. 2011) (quotation marks omitted). However, when a jury instruction “hinges
    on a question of statutory construction, [our] review is de novo.” United States
    v. Wright, 
    634 F.3d 770
    , 774 (5th Cir. 2011).
    1.       Conspiracy Instructions
    First, the Defendants-Appellants argue that the district court incorrectly
    instructed the jury on the mens rea of conspiracy and conspiracy to commit wire
    fraud in a response to a jury note. In its jury instructions, based on the Fifth
    Circuit Pattern Criminal Instructions, the district court instructed that to
    convict for conspiracy under 
    18 U.S.C. § 371
    , the jury must find:14
    First: That two or more persons made an agreement to commit the
    crime of false reporting or wire fraud as charged in the indictment;
    14
    
    18 U.S.C. § 371
     provides:
    If two or more persons conspire either to commit any offense against the United
    States, or to defraud the United States, or any agency thereof in any manner or
    for any purpose, and one or more of such persons do any act to effect the object
    of the conspiracy, each shall be fined under this title or imprisoned not more
    than five years, or both.
    24
    Case: 09-20871        Document: 00511861304       Page: 25     Date Filed: 05/18/2012
    No. 09-20871
    Second: That the defendant knew the unlawful purpose of the
    agreement and joined in it willfully, that is, with the intent to
    further the unlawful purpose; and
    Third: That one of the conspirators during the existence of the
    conspiracy knowingly committed at least one of the overt acts
    described in the indictment, in order to accomplish some object or
    purpose of the conspiracy.
    The district court also explained that under the first element the jurors need to
    “agree that the government proved beyond a reasonable doubt that the
    defendants conspired to commit false reporting; or, all of you must agree that the
    government proved beyond a reasonable doubt that the defendants conspired to
    commit wire fraud.” The district court instructed that to convict someone of wire
    fraud under 
    18 U.S.C. § 1343
    ,15 the jury must find:
    First: That the defendant knowingly created a scheme or artifice to
    defraud or to obtain money, property or other things of value by
    means of material false or fraudulent pretenses, representations or
    promises as set out in the indictment;
    Second: That the defendant acted with a specific intent to defraud;
    Third: That the defendant used interstate wire communications
    facilities or caused another person to use interstate wire
    communications facilities for the purpose of carrying out the
    scheme; and
    Fourth: That the scheme to defraud employed false material
    representations.
    The district court explained that “‘specific intent to defraud’ means an intent to
    specifically deceive or cheat someone.”
    During its deliberations, the jury sent the district court a note asking:
    15
    
    18 U.S.C. § 1343
     provides:
    Whoever, having devised or intending to devise any scheme or artifice to
    defraud, or for obtaining money or property by means of false or fraudulent
    pretenses, representations, or promises, transmits or causes to be transmitted
    by means of wire, radio, or television communication in interstate or foreign
    commerce, any writings, signs, signals, pictures, or sounds for the purpose of
    executing such scheme or artifice, shall be fined under this title or imprisoned
    not more than 20 years, or both.
    25
    Case: 09-20871       Document: 00511861304          Page: 26      Date Filed: 05/18/2012
    No. 09-20871
    In the second part of Count 1 it states, “that the Defendant knew
    the unlawful purpose.” Doesn’t this contradict the idea that
    “ignorance of the law is no excuse.”
    After a conference with the parties, the district court replied to the note, writing:
    There is no contradiction. The government is not required to prove
    that a defendant knew the purpose of the agreement was in fact
    unlawful, that is, in violation of a statute, but the government must
    prove the defendant knew the purpose of the agreement, and the
    government must prove that the purpose was in fact unlawful.
    The Defendants-Appellants argue that this answer misstates the mens rea
    required to prove conspiracy and conspiracy to commit wire fraud.
    A conviction for conspiracy under Section 371 requires that the
    government prove: “(1) an agreement between two or more persons to pursue an
    unlawful objective; (2) the defendant’s knowledge of the unlawful objective and
    voluntary agreement to join the conspiracy; and (3) an overt act by one or more
    of the members of the conspiracy in furtherance of the objective of the
    conspiracy.” United States v. Coleman, 
    609 F.3d 699
    , 704 (5th Cir. 2010); see
    also United States v. Curtis, 
    635 F.3d 704
    , 719 n.53 (5th Cir. 2011). Conspiracy
    actually has two intent elements—intent to further the unlawful purpose and
    the level of intent required for proving the underlying substantive offense. See
    2 Wayne R. LaFave & Austin W. Scott, Jr., Substantive Criminal Law §
    12.2(c)(1) (2003); United States v. Alvarez, 
    610 F.2d 1250
    , 1255 (5th Cir. 1980)
    (“Conspiracy is, however, more complex because it involves two elements of
    intent that shade into each other: each party must have intended to enter into
    the agreement and the schemers must have had a common intent to commit an
    unlawful act.”).16
    16
    Although the two intents are separate, they often functionally collapse into a single
    intent. United States v. Chagra, 
    807 F.2d 398
    , 401 (5th Cir. 1986). Thus, oftentimes, it is only
    necessary for the government to prove the level of intent required for proving the underlying
    substantive offense. United States v. Feola, 
    420 U.S. 671
    , 686 (1975); United States v. Dadi,
    
    235 F.3d 945
    , 950 (5th Cir. 2000).
    26
    Case: 09-20871       Document: 00511861304           Page: 27      Date Filed: 05/18/2012
    No. 09-20871
    The Defendants-Appellants first seem to argue that proving conspiracy
    always requires proof the defendant knew his conduct was unlawful, regardless
    of the mens rea of the underlying substantive offense.                     This argument is
    inconsistent, however, with the Supreme Court’s opinion in Ingram v. United
    States, 
    360 U.S. 672
     (1959). In that decision, the Supreme Court stated that to
    convict for conspiracy, “[t]here need not, of course, be proof that the conspirators
    were aware of the criminality of their objective,” but rather, there must only be
    proof of knowledge of the unlawful conduct. 
    Id. at 678
    . This holding was
    reaffirmed in United States v. Feola. 
    420 U.S. 671
     (1975). In Feola, the
    Supreme Court again stated that the government need not prove anything more
    than the degree of criminal intent necessary for the substantive offense in order
    to convict a defendant of conspiracy. 
    Id.
     at 686–87. Thus, to the extent that the
    Defendants-Appellants argue that conspiracy always requires proof that the
    defendant knew his conduct was unlawful, we reject their argument. See United
    States v. Blair, 
    54 F.3d 639
    , 642–43 (10th Cir. 1995) (rejecting same argument
    and stating that since “‘one can violate a criminal statute simply by engaging in
    the forbidden conduct, a conspiracy to commit that offense is nothing more than
    an agreement to engage in the prohibited conduct’” (quoting Feola, 
    420 U.S. at 687
    )).17
    More specific to the wire fraud offense, the Defendants-Appellants argue
    that the answer to the jury’s question was erroneous because it improperly
    lowered the intent required to prove conspiracy to commit wire fraud. They
    argue that the response improperly led the jury to believe that the Defendants-
    17
    See also United States v. Ramiscal, 
    99 F.3d 1148
     (9th Cir. Oct. 18, 1996)
    (unpublished) (rejecting argument that proof of conspiracy always requires proof of knowledge
    of illegality of conduct); United States v. Jo, 
    99 F.3d 1147
     (9th Cir. Oct. 18, 1996) (unpublished)
    (same);United States v. Sclamo, 
    578 F.2d 888
    , 891 (1st Cir. 1978) (rejecting similar argument
    and stating, “[t]he underlying substantive statute does not require a showing of specific Mens
    rea; the conspiracy count requires no greater degree of scienter than the substantive count”).
    27
    Case: 09-20871    Document: 00511861304      Page: 28   Date Filed: 05/18/2012
    No. 09-20871
    Appellants could be convicted even if they lacked specific intent to defraud. This
    is closer, but again, we do not find the Defendants-Appellants’ argument
    persuasive.
    To prove wire fraud, the government must prove: (1) a scheme or artifice
    to defraud; (2) material falsehoods; and (3) the use of interstate wires in
    furtherance of the scheme. See Curtis, 
    635 F.3d at
    718 n.49; United States v.
    McMillan, 
    600 F.3d 434
    , 447 n.24 (5th Cir. 2010). Violation of the wire-fraud
    statute requires the specific intent to defraud, i.e., a “conscious knowing intent
    to defraud.” United States v. Reyes, 
    239 F.3d 722
    , 736 (5th Cir. 2001). Thus,
    proving conspiracy to commit wire fraud requires proof that the Defendants-
    Appellants joined the conspiracy with the specific intent to defraud. See Curtis,
    
    635 F.3d at
    719 n.53. The district court’s response to the jury’s note accurately
    describes this intent requirement.
    The jury note states that as to the conspiracy statute itself, ignorance of
    the law is no excuse, because “[t]he government is not required to prove that a
    defendant knew the purpose of the agreement was in fact unlawful, that is, in
    violation of a statute, but the government must prove the defendant knew the
    purpose of the agreement.” See Ingram, 
    360 U.S. at 678
    . The note also
    accurately states that the government must prove that the purpose was in fact
    unlawful, which requires proof that the Defendants-Appellants acted with the
    requisite mens rea to commit wire fraud.         Coleman, 
    609 F.3d at
    704–06
    (analyzing whether elements of target offense also met when determining if
    conspiracy to commit that offense proven); United States v. Bedford, 
    536 F.3d 1148
    , 1155 (10th Cir. 2008) (stating government must prove degree of criminal
    intent necessary to prove underlying crime). Although the district court’s
    response possibly could have spelled out the relationship between conspiracy and
    the underlying substantive offenses more clearly, it is not an incorrect statement
    of the law, particularly in light of the rest of the jury charge. See United States
    28
    Case: 09-20871       Document: 00511861304           Page: 29      Date Filed: 05/18/2012
    No. 09-20871
    v. Chavis, 
    772 F.2d 100
    , 108 (5th Cir. 1985) (“The jury charge must . . . be
    considered as a whole, in the full context of the trial.”).18
    Therefore, we conclude that the district court’s instructions and the note
    to the jury were an accurate statement of the mens rea required to convict for
    conspiracy to commit wire fraud.
    2.      Deliberate Ignorance Instruction
    Next, the Defendants-Appellants argue that the district court’s jury
    instruction on deliberate ignorance impermissibly lowered the mens rea of both
    offenses. The district used the Pattern Fifth Circuit instruction, and instructed:
    You may find that a defendant had knowledge of a fact if you find
    that the defendant deliberately closed his eyes to what would
    otherwise have been obvious to him. While knowledge on the part
    of the defendant cannot be established merely by demonstrating
    that the defendant was negligent, careless, or foolish, knowledge can
    be inferred if the defendant deliberately blinded himself to the
    existence of a fact.
    Fifth Circuit Pattern Criminal Jury Instructions, § 1.37. The Defendants-
    Appellants argue that these instructions were incorrect on two grounds: first,
    18
    The Defendants-Appellants also argue that the note gave the jury the impression
    that the maxim “ignorance of the law is no excuse” was officially a jury instruction. Whether
    or not it was proper for the district court to implicitly adopt this statement, the note accurately
    stated that this case did not fall within the narrow exception to the traditional rule that
    “ignorance of the law is no excuse,” as laid out by the Supreme Court. The Supreme Court
    stated that “the traditional rule that ignorance of the law is no excuse” does not apply only in
    cases involving highly technical statutes that criminalize otherwise “innocent conduct.”
    Bryan v. United States, 
    524 U.S. 184
    , 194–96 (1998); see also Ratzlaf v. United States, 
    510 U.S. 135
    , 149 (1994); Cheek v. United States, 
    498 U.S. 192
    , 199–200 (1991). Although wire fraud
    is a specific intent crime, it would not fall into this narrow exception to the general rule. See
    Kay, 
    513 F.3d at
    447–51 (describing narrow exception to traditional rule that ignorance of the
    law is no excuse). Further, to the extent that the Defendants-Appellants argue that this
    instruction gave the jury the impression that it could not acquit, even if it found that the
    Defendants-Appellants believed they were giving accurate answers to the publications, the
    instruction on specific intent to defraud made clear to the jury that it could not convict unless
    it found a “conscious knowing intent to defraud.” See United States v. Cavin, 
    39 F.3d 1299
    ,
    1310 (5th Cir. 1994) (a finding of intent to defraud and good faith are mutually exclusive).
    Taken in context with the rest of the instructions, and the remainder of the note, we do not
    think that the statement regarding “ignorance of the law” was in error.
    29
    Case: 09-20871    Document: 00511861304     Page: 30   Date Filed: 05/18/2012
    No. 09-20871
    that the evidence did not support the instruction; and second, that the
    instruction was legally incorrect.
    On the first argument, a deliberate ignorance instruction is warranted
    “when a defendant claims a lack of guilty knowledge and the proof at trial
    supports an inference of deliberate indifference.” United States v. Moreno, 
    185 F.3d 465
    , 476 (5th Cir. 1999) (quotation omitted). “The evidence at trial must
    raise two inferences:   (1) the defendant was subjectively aware of a high
    probability of the existence of the illegal conduct; and (2) the defendant
    purposely contrived to avoid learning of the illegal conduct.” United States v.
    Lara–Velasquez, 
    919 F.2d 946
    , 951 (5th Cir. 1990). In assessing whether
    evidence sufficiently supports the instruction, we “view the evidence and all
    reasonable inferences that may be drawn from the evidence in the light most
    favorable to the [g]overnment.” United States v. Mendoza-Medina, 
    346 F.3d 121
    ,
    132 (5th Cir. 2003) (quotation omitted); United States v. Gray, 
    105 F.3d 956
    , 967
    (5th Cir. 1997).
    The first requirement for using the instruction—the defendant claims a
    lack of guilty knowledge—is not disputed by the parties.            The second
    requirement—the defendant purposely contrived to avoid learning of the illegal
    conduct—is satisfied if the evidence at trial raises an inference that: (1) the
    defendant was subjectively aware of a high probability of the existence of the
    illegal conduct; and (2) the defendant purposely contrived to avoid learning of
    the illegal conduct.    Lara-Velasquez, 
    919 F.2d at 951
    .       Here, taking all
    reasonable inference in the government’s favor, there is more than sufficient
    evidence to find that the Defendants-Appellants were subjectively aware of a
    high probably of the existence of illegal conduct and that they purposely
    contrived to avoid learning of the illegal conduct.
    On this first prong, a review of the record shows that there was a great
    deal of evidence admitted at trial showing that the Defendants-Appellants
    30
    Case: 09-20871    Document: 00511861304     Page: 31    Date Filed: 05/18/2012
    No. 09-20871
    believed that their conduct was illegal, or were aware of a high probability that
    it was illegal. For example, testimony at trial revealed that Brooks told co-
    workers that they would “be toast” if the government looked into their index
    reporting practices, and later, Brooks ordered traders to delete all copies of the
    reports that had been sent to the trade publications. Similarly, all of the
    Defendants-Appellants were involved in the email communication where the
    traders decided to continue reporting based on “book bias.” In that email
    exchange, the traders discussed how they should not discuss this topic over
    email—an obvious inference from these comments is that the traders were aware
    their “book bias” method of reporting was likely illegal. Finally, taking a step
    back, it is simply unbelievable to think that sophisticated gas traders, such as
    the Defendants-Appellants, did not realize that falsely reporting data to steal
    money from basis trading partners was, in all likelihood, criminalized under
    some statute.
    On the second prong, the Defendants-Appellants argue that there is no
    evidence that they “purposefully contrived to avoid learning of illegal conduct.”
    Specifically, the Defendants-Appellants claim that they did not know the actual
    instructions sent by the publications, and that they thought they were sending
    the correct information. There is evidence in the record, however, showing that
    the Defendants-Appellants purposely avoided learning of the illegal nature of
    the conduct. For example, both Brooks and Phillips repeatedly ignored the
    reporting instructions, and they both also had conversations with Kelley Doolan,
    an editor at Inside FERC, about the reporting requirements. Similarly, other
    evidence indicated that Walton had been forwarded a spreadsheet with fake
    trades, and that he was included in the “book bias” email, in which the traders
    made statements indicating that their reporting practices were not in line with
    Inside FERC’s instructions. Based on this evidence, we hold that it was not an
    31
    Case: 09-20871       Document: 00511861304          Page: 32      Date Filed: 05/18/2012
    No. 09-20871
    abuse of discretion for the district court to instruct the jury on deliberate
    ignorance.
    Second, the Defendants-Appellants argue that the instruction on
    deliberate ignorance was an improper statement of the law in light of the
    Supreme Court’s recent decision in Global-Tech Appliances, Inc. v. SEB S.A., 
    131 S. Ct. 2060
     (2011). In Global-Tech, the Supreme Court considered willful
    blindness in the civil context, stating that willful blindness requires proof that:
    “(1) the defendant [ ] subjectively believe[d] that there [was] a high probability
    that a fact exists and (2) the defendant [took] deliberate actions to avoid learning
    of that fact.” 
    Id. at 2070
    . The Court continued, stating that willful blindness
    “surpasses recklessness and negligence,” and that “a willfully blind defendant
    is one who takes deliberate actions to avoid confirming a high probability of
    wrongdoing and who can almost be said to have actually known the critical
    facts.” 
    Id.
     at 2070–71.
    The Fifth Circuit Pattern Instruction meets the standard set forth by the
    Supreme Court in Global-Tech.19 The instructions do not have the same failings
    as the Federal Circuit standard reversed in Global Tech, which allowed for a
    finding of willful blindness where there is only a “known risk,” and where the
    defendant did not make an active effort to avoid knowledge. Global-Tech, 
    131 S. Ct. at 2071
    . As to Global Tech’s first prong—the defendant “must subjectively
    believe that there is a high probability that a fact exists”—the jury instruction
    provided that the defendant needed to have “deliberately closed his eyes” to a
    fact that “would otherwise have been obvious to him.”                     As to the second
    prong—the defendant “must take deliberate actions to avoid learning of that
    19
    Although Global-Tech was a civil case, the standard seems to apply equally to
    criminal deliberate ignorance cases. See United States v. Ferguson, --- F.3d ----, 
    2011 WL 6351862
    , at *10 n.16 (2d Cir. Dec. 19, 2011) (applying standard in criminal case and noting
    slight differences in terminology); United States v. Butler, 
    646 F.3d 1038
    , 1041 (8th Cir. 2011)
    (same).
    32
    Case: 09-20871    Document: 00511861304       Page: 33    Date Filed: 05/18/2012
    No. 09-20871
    fact”—the instruction provided that the defendant needed to have “deliberately
    closed his eyes,” and “deliberately blinded himself to the existence of a fact.” The
    instruction also stated that merely finding the defendants were “negligent,
    careless, or foolish” was insufficient. Thus, although this instruction obviously
    does not use the same language as Global-Tech, the same meaning is conveyed.
    Accordingly, not only was the deliberate ignorance instruction justified, the
    instruction itself was legally correct.
    3.    False Reporting Instruction
    The Defendants-Appellants also argue that the jury instructions were in
    error because the district court incorrectly stated the elements of false reporting
    under the CEA, 
    7 U.S.C. § 13
    (a)(2).
    In relevant part, the CEA provides that “[i]t shall be a felony . . . for . . .
    [a]ny person . . . knowingly to deliver or cause to be delivered for transmission
    through the mails or interstate commerce by telegraph, telephone, wireless, or
    other means of communication false or misleading or knowingly inaccurate
    reports concerning crop or market information or conditions that affect or tend
    to affect the price of any commodity in interstate commerce . . . .” 
    7 U.S.C. § 13
    (a)(2). The district court instructed the jury that to convict it must find that
    the Defendants-Appellants: (1) “knowingly delivered, or caused to be delivered,
    for transmission through interstate commerce by telephone or other means of
    communication a material false or misleading or inaccurate report”; (2) “knew
    the report was false or misleading or inaccurate; and (3) “[t]hat the report
    concerned market information or conditions that affected or tended to affected
    the price of a commodity in interstate commerce.” The Defendants-Appellants
    argue that the mens rea of false reporting—knowingly—requires that a
    defendant must “know” his reports would “affect or tend to affect the price of any
    commodity in interstate commerce.”

    No. 09-20871
    In Valencia, the Court found that “knowingly” in this section of the CEA
    applies both to the transmission and falsity of the report (elements one and two),
    but that decision did not reach whether it applied to the final element of the
    offense. 
    394 F.3d at
    354–56.20 It is not clear whether “knowingly” applies to all
    of the elements of the offense. As a matter of natural reading and grammar,
    there is not an interpretation of the language that clearly makes the most sense.
    See generally Flores-Figueroa v. United States, 
    556 U.S. 646
     (2009) (applying
    “ordinary English grammar” to construe statute’s knowledge requirement); see
    also United States v. Betancourt, 
    586 F.3d 303
    , 308–09 (5th Cir. 2009)
    (determining whether mens rea applies to elements of an offense after Flores-
    Figueroa). The Defendants-Appellants argue that the mens rea should be
    applied to the final element of the offense based on the Supreme Court’s decision
    in United States v. X-Citement Video, Inc., 
    513 U.S. 64
     (1994). In X-Citement
    Video, the Supreme Court read the term “knowingly” as applying to each
    element of a child pornography offense, even though the “most                         natural
    grammatical reading” of the statute did not suggest this result. See 
    id. at 68
    .
    In reaching this conclusion, the Supreme Court set forth a general rule that a
    “scienter requirement should apply to each of the statutory elements that
    criminalize otherwise innocent conduct.” See 
    id.
     at 72 (citing Staples v. United
    States, 
    511 U.S. 600
    , 619 (1994)); see also Carter v. United States, 
    530 U.S. 255
    ,
    269 (2000) (reaffirming X-Citement Video rule); Valencia, 
    394 F.3d at
    354–56
    (applying the X-Citement Video rule to the CEA). Here though, the first two
    elements of the offense already require that a defendant knowingly transmit a
    knowingly false statement, largely taking the criminalized conduct out of the
    20
    Although obviously not dispositive, our decision in Valencia has been interpreted by
    other courts as only requiring knowledge as to the first two elements of the offense. See, e.g.,
    Atha, 
    420 F. Supp. 2d at 1380
    ; CFTC v. Johnson, 
    408 F. Supp. 2d at 267
    . This Court also
    adopted that interpretation in Futch, 278 F. App’x at 391, although that is an unpublished and
    non-precedential decision.

    realm of innocent activity. See United States v. Butler, 
    637 F.3d 519
    , 524 (5th
    Cir. 2011) (stating that Staples and X-Citement Video presumption does not
    apply where statute “does not entail the risk of subjecting ordinary citizens to
    criminal prosecution for otherwise innocent conduct”).21
    Overall, it is not clear whether knowledge applies to the requirement that
    the false report affect or tend to affect the price of a commodity. However, even
    assuming that the Defendants-Appellants are correct in their interpretation of
    the statute, we need not reverse their convictions. Where a trial court misstates
    or omits an element of an offense, the conviction is reviewed for harmless error.
    See Neder v. United States, 
    527 U.S. 1
    , 9–10 (1999); Pope v. Illinois, 
    481 U.S. 497
    , 501–04 (1987); United States v. Bohuchot, 
    625 F.3d 892
    , 903 (5th Cir. 2010);
    United States v. Delgado, 
    256 F.3d 264
    , 280–81 (5th Cir. 2001). Under this plain
    error standard, the conviction should be affirmed if it is “clear beyond a
    reasonable doubt that a rational jury would have found the defendant guilty
    absent the error.” Neder, 
    527 U.S. at 18
    ; accord United States v. Skilling, 
    638 F.3d 480
    , 481–82 (5th Cir. 2011).
    Here, there was a great deal of evidence admitted at trial showing that the
    Defendants-Appellants knew their price reports would or had affected natural
    gas indexes. For example, according to Dean, Brooks told him that they “gamed
    the system” and that Dean needed to report trades that would favorably affect
    the index prices. Additionally, in the October 2000 “book bias” email, Brooks
    wrote to the other traders that “we reported only verifiable fixed price

    transactions to IF for October” and “[it] only eliminated us as an active price
    setting participant.” O’Toole and Dean both also testified that they were
    instructed by Phillips or Brooks to coordinate their reports with Walton, and
    that Walton would give them target prices for the indexes. Additionally, there
    were numerous recorded conversations and emails entered into evidence, during
    which Walton and Phillips discussed the manner certain reports would or had
    affected index prices. Moreover, the jury convicted the Defendants-Appellants
    for wire fraud on every count that it convicted them for false reporting. In doing
    so, the jury found that the Defendants-Appellants had specific intent to defraud
    when submitting these false reports, which indicates that the jury also believed
    that the Defendants-Appellants had knowledge that their reporting would affect
    index prices.
    Given this evidence, it is “clear beyond a reasonable doubt that a rational
    jury” would have found that the Defendants-Appellants had knowledge that
    their reports affected or tended to affect the price of natural gas. Accordingly,
    we decline to decide whether the mens rea applies to the final element of false
    reporting, because even assuming that it does, the error would be harmless.
    4.    Cumulative Error
    Finally, the Defendants-Appellants argue that the cumulative error of the
    jury instructions errors requires reversal. “[T]he cumulative error doctrine . . .
    provides that an aggregation of non-reversible errors (i.e., plain errors failing to
    necessitate reversal and harmless errors) can yield a denial of the constitutional
    right to a fair trial, which calls for reversal.” United States v. Munoz, 
    150 F.3d 401
    , 418 (5th Cir. 1998). Beyond the issue of whether the mens rea applied to
    the final element of the false reporting offense—which we are confident was
    36
    Case: 09-20871       Document: 00511861304           Page: 37      Date Filed: 05/18/2012
    No. 09-20871
    harmless if it was erroneous—we found no errors in the jury instructions.
    Therefore, we hold that the cumulative error doctrine does not require reversal.22
    D. Fundamental and Arguable Ambiguity
    The Defendants-Appellants also argue that the questions on the Inside
    FERC and NGI surveys were fundamentally ambiguous—requiring a judgment
    of acquittal—or that the district court should have given the jury an arguable
    ambiguity instruction.
    First, the Defendants-Appellants argue that the district court erred by
    denying their motion for acquittal because they were convicted for answering
    fundamentally ambiguous questions. Specifically, they argue that there are not
    universally accepted definitions for the terms “trading location,” “bidweek,”
    “baseload,” or “fixed price.” This court reviews the district court’s denial of a
    motion for acquittal de novo. United States v. Bennett, 
    664 F.3d 997
    , 1011–12
    (5th Cir. 2011).
    22
    The Defendants-Appellants also briefly challenge the district court’s denial of a good
    faith instruction and an instruction that failure to follow Inside FERC’s instructions, standing
    alone, is not a crime. As to the good faith instruction, the district court did not abuse its
    discretion in denying it. “The district court will not abuse its discretion when it denies a
    proffered instruction unless this instruction (1) was a correct statement of the law, (2) was not
    substantially covered in the charge as a whole, and (3) concerned an important point in the
    trial such that the failure to instruct the jury on the issue seriously impaired the defendant’s
    ability to present a given defense.” United States v. Jobe, 
    101 F.3d 1046
    , 1059 (5th Cir. 1996)
    (citation and quotation marks omitted). A district court may “refuse to submit an instruction
    regarding a good faith defense if the defense is substantially covered by the charge given and
    the defendant has had the opportunity to argue good faith to the jury.” United States v. Upton,
    
    91 F.3d 677
    , 683 (5th Cir. 1996) (quotation omitted). Here, the Defendants-Appellants were
    permitted to argue that they acted in good faith and had no intent to defraud, and the jury
    instructions accurately conveyed the specific intent required to both commit fraud and
    conspiracy. See United States v. Storm, 
    36 F.3d 1289
    , 1294–95 (5th Cir. 1994) (refusing to find
    error where “defense of good faith was substantially covered by charge to the jury” on the
    terms “‘knowingly’ and ‘willfully’”).
    Second, the Defendants-Appellants proposed instruction that a failure to follow Inside
    FERC’s instructions, by itself, is not evidence of a crime, is confusing and the instruction likely
    would have misled the jury. Further, the instruction seems to be inaccurate, given that a
    failure to follow Inside FERC’s instructions alone, with the proper intent, could constitute
    false reporting or wire fraud. Thus, denying this instruction was also not an abuse of
    discretion. See Jobe, 
    101 F.3d at 1059
    .

    No. 09-20871
    To be fundamentally ambiguous, a “question must lack ‘a meaning about
    which men of ordinary intellect could agree, nor one which could be used with
    mutual understanding by a questioner and answerer unless it were defined at
    the time it were sought and offered as testimony.’” United States v. Strohm, 
    671 F.3d 1173
    , 1179 (10th Cir. 2011) (quoting United States v. Farmer, 
    137 F.3d 1265
    , 1269 (10th Cir. 1998)); accord United States v. Culliton, 
    328 F.3d 1074
    ,
    1078 (9th Cir. 2003). The question must be so vague that it is impossible to have
    intended to answer it untruthfully. United States v. Richardson, 
    421 F.3d 17
    ,
    33 (1st Cir. 2005). Where a question is found to be fundamentally ambiguous,
    a defendant’s answer to it is insufficient as a matter of law to sustain a
    conviction. Richardson, 
    421 F.3d at 33
    . A question is fundamentally ambiguous,
    however, in only very “narrow circumstances.” Strohm, 
    671 F.3d at 1179
    ; United
    States v. Damrah, 
    412 F.3d 618
    , 627 (6th Cir. 2005) (stating that doctrine
    applies only in “exceptional” cases). If a witness “knowingly made a false
    statement, based on his or her understanding of the question,” the doctrine does
    not apply, Strohm, 
    671 F.3d at 1180
    , and a witness cannot “twist the meaning
    of a question in his own mind into some totally unrecognizable shape and then
    hide behind it by alleging its fundamental ambiguity,” Richardson, 
    421 F.3d at 35
     (quotation omitted).
    Given the context in which the fundamental ambiguity defense has been
    applied previously, we hold that it does not apply under the facts of this case.
    It is completely implausible to think that the Defendants-Appellants reported
    fabricated trades based on a misinterpretation of the instructions.          The
    fundamental ambiguity defense does not apply where a defendant “twist[s] the
    meaning of a question in his own mind into some totally unrecognizable shape
    and then hide[s] behind it by alleging its fundamental ambiguity.” Richardson,
    
    421 F.3d at 35
     (quotation omitted); see also Farmer, 
    137 F.3d at 1269
     (stating
    that a question cannot be isolated from context to engineer ambiguity); United
    38
    Case: 09-20871       Document: 00511861304         Page: 39     Date Filed: 05/18/2012
    No. 09-20871
    States v. Carey, 
    152 F. Supp. 2d 415
    , 427 (S.D.N.Y. 2001) (defense does not apply
    where an “answer to an ambiguous question is false under any reasonable
    interpretation”). There is no reasonable interpretation of the instructions that
    would allow reporting invented and fabricated trades. Indeed, the Defendants-
    Appellants are unable to cite any actual trade that was mistakenly reported due
    to specific ambiguities in the survey instructions.23
    Additionally, as to the only Defendant-Appellant who testified, Brooks
    stated at trial that he either (1) did not ever read Inside FERC’s instructions, or
    (2) consciously disregarded the instructions and submitted invented data as a
    means of reporting “fair market value” (or “book bias”) to make the indexes more
    accurate, even though he knew the publications only wanted actual trades. In
    either case, Brooks admits that the instructions did not cause the type of false
    reporting that occurred. See United States v. Mubayyid, 
    658 F.3d 35
    , 63 (1st Cir.
    2011) (holding that, if the defendant gave a false response based on how he
    understood the question, his conviction would not be invalidated due to
    ambiguity in question); Culliton, 328 F.2d at 1079 (“[The defendant] points to no
    case, and indeed we have found none, that justifies an applicant’s unilateral
    reinterpretation of questions . . . to comport with his own particular goals.”);
    United States v. Bollin, 
    264 F.3d 391
    , 411 (4th Cir. 2001) (holding defense not
    available where defendant testified in a manner that he knew was false, even if
    question open to multiple interpretations). Accordingly, we hold that the district
    court did not err in denying the motion for acquittal based on the ambiguity of
    the terminology in the reporting instructions.
    23
    At oral argument and in their briefing, the Defendants-Appellants state that Inside
    FERC survey question, given the ambiguous terms, functionally was: “What undefined type
    of trades that may or may not call for delivery of gas for an unspecified time did you conduct
    during some time frame and that occurred in an area without geographic boundaries.”
    However, even based on the Defendants-Appellants’ characterization of the instructions, they
    gave false responses because the question only requests trades that were actually conducted.
    39

    No. 09-20871
    Second, the Defendants-Appellants argue that even if Inside FERC’s
    instructions were not fundamentally ambiguous, the district court abused its
    discretion by denying a jury instruction on arguable ambiguity. As we noted
    earlier, “[d]istrict courts enjoy substantial latitude in formulating a jury charge,
    and hence we review all challenges to, and refusals to give, jury instructions for
    abuse of discretion.” United States v. Carrillo, 
    660 F.3d 914
    , 925–26 (5th Cir.
    2011) (quotation omitted). “We consider whether the instruction, taken as a
    whole, ‘is a correct statement of the law and whether it clearly instructs jurors
    as to the principles of law applicable to the factual issues confronting them.’”
    United States v. Freeman, 
    434 F.3d 369
    , 377 (5th Cir. 2005) (quoting United
    States v. Daniels, 
    281 F.3d 168
    , 183 (5th Cir. 2002)). It is “reversible error to
    refuse a charge on a defense theory for which there is an evidentiary foundation
    and which, if believed by the jury, would be legally sufficient to support a verdict
    of not guilty.” United States v. Barnett, 
    197 F.3d 138
    , 142 (5th Cir. 1999)
    (quotation omitted). An instruction on a defense theory, however, only need be
    given where “there exists evidence sufficient for a reasonable jury to find in [the
    defendant’s] favor.” United States v. Mata, 
    491 F.3d 237
    , 241 (5th Cir. 2007).
    During the jury charge conference, the Defendants-Appellants requested
    that the following jury instruction be given, which was adapted from the Fifth
    Circuit Pattern Jury Instruction Section 2.69, on perjury:
    If you should find that a particular question was ambiguous and
    that the defendant truthfully answered one reasonable
    interpretation of the question under the circumstances presented,
    then such answer would not be false. Similarly, if you should find
    that the question was clear, but the answer was ambiguous, and one
    reasonable interpretation of such answer would be truthful, then
    such answer would not be false.
    Fifth Circuit Pattern Criminal Jury Instructions § 2.69. The district court
    denied this instruction. The Defendants-Appellants argue that their defense
    40
    Case: 09-20871     Document: 00511861304        Page: 41    Date Filed: 05/18/2012
    No. 09-20871
    revolved around showing that the instructions from Inside FERC were
    ambiguous and that not allowing the instruction prevented them from
    presenting their theory to the jury.
    A determination of whether a question or statement is arguably
    ambiguous is generally left to the jury. See, e.g., United States v. Posada
    Carilles, 
    541 F.3d 344
    , 362–63 (5th Cir. 2008) (stating that jury resolves
    ambiguities where they are not fundamental); United States v. Bell, 
    623 F.2d 1132
    , 1136 (5th Cir. 1980) (same). It is not clear whether an arguable ambiguity
    instruction is appropriate in cases charging false reporting and wire fraud.24 In
    support of their argument, the Defendants-Appellants rely upon a Tenth Circuit
    case, United States v. Migliaccio, 
    34 F.3d 1517
     (10th Cir. 1994), in which the
    doctrine was applied to a charge of fraud under facts somewhat similar to the
    current suit. In that case, the Tenth Circuit held that not allowing an arguable
    ambiguity instruction was reversible error where the defendants were charged
    with fraudulent billing of medical procedures. 
    Id.
     at 1520–25. The defendants
    argued that the terminology was ambiguous and that their answers were
    truthful under their interpretation of the terms. 
    Id.
    Here, in making their argument, the Defendants-Appellants ignore the
    fact that such an ambiguity instruction is only appropriate in cases where the
    defendant’s claimed interpretation of the ambiguous terms is reasonable and is
    supported by the record. Migliaccio, 
    34 F.3d at 1525
    . In United States v.
    Lawrence, the Tenth Circuit discussed Migliaccio and affirmed a district court’s
    denial of an ambiguity instruction in a wire fraud case. 
    405 F.3d 888
    , 896–900
    (10th Cir. 2005). In doing so, the court stated that an ambiguity instruction “is
    only necessary where there is evidence supporting the defendant’s interpretation
    as reasonable.” 
    Id. at 898
    . Indeed, it is accepted law that a defendant is only
    24
    See United States v. Munoz, 
    233 F.3d 1117
    , 1130–32 (9th Cir. 2000) (stating that
    ambiguity instruction not appropriate in fraud case due to broad nature of statute).

    Case: 09-20871        Document: 00511861304           Page: 42     Date Filed: 05/18/2012
    No. 09-20871
    entitled to an instruction on a defense theory where there is sufficient evidence
    such that a reasonable jury could find in his favor on that theory. See United
    States v. Branch, 
    91 F.3d 699
    , 712–13 (5th Cir. 1996).
    As explained previously, there is no reasonable interpretation of the
    instructions that allows the reporting of completely fabricated data. This
    interpretation is divorced from the language of the instructions, and it has no
    relationship to the allegedly ambiguous terminology.                     The district court,
    therefore, appropriately denied the ambiguity instruction.25 See Lawrence, 
    405 F.3d at 898
    ; Migliaccio, 
    34 F.3d at 1525
    .26
    E. Evidentiary Rulings
    The Defendants-Appellants also appeal several of the district court’s
    evidentiary rulings. Specifically, the Defendants-Appellants challenge: (1) the
    district court’s exclusion of their industry practice evidence; (2) the district
    court’s admission of the testimony of Matthew O’Loughlin, the government’s
    25
    Because the arguable ambiguity instruction is not supported by the record, we
    decline to decide whether such an instruction is ever appropriate in cases charging fraud or
    false reporting.
    26
    Additionally, it is not an abuse of discretion for a district court to deny a proposed
    jury instruction where the defense theory was adequately presented to the jury. See United
    States v. Gray, 
    751 F.2d 733
    , 736–37 (5th Cir. 1985). For example, in the case of a proposed
    good faith defense, we have held that denial of a specific instruction is not an abuse of
    discretion where the content of the defense is raised during argument and the jury is
    accurately instructed on specific intent to defraud. See United States v. Bilotto, 245 F. App’x
    410, 413–14 (5th Cir. 2007) (per curiam); United States v. Manges,

    on ambiguity, the Defendants-Appellants were permitted to present this argument to the jury,
    and in fact, Phillips’s lawyer discussed how the ambiguous terms negated the intent elements
    of the charged offenses during closing arguments at length. Further, the district court
    accurately instructed the jury on how both offenses require knowledge of the falsity of the
    statement, which prevented the jury from convicting if it found that the Defendants-
    Appellants actually believed that they were complying with the instructions. Thus, the district
    court’s charge “enabled the jury to recognize and understand the defense theory, [to] test it
    against the evidence presented at trial, and then [to] make a definitive decision whether,
    based on that evidence and in light of the defense theory, the defendant was guilty or not
    guilty.” Gray, 
    751 F.2d at
    736–37 (quotation omitted).

    expert witness; and (3) the district court’s decision not to immunize Don
    Guilbault, a potential defense witness. We will consider these rulings in turn.
    First, the Defendants-Appellants argue that the district court erred by
    excluding evidence related to industry practice. Specifically, the Defendants-
    Appellants argue that they were prevented from proving their good faith defense
    because they were barred from presenting evidence showing that other energy
    companies were also submitting similarly false data to Inside FERC and NGI.
    We review evidentiary rulings for abuse of discretion, subject to harmless
    error analysis. United States v. Isiwele, 
    635 F.3d 196
    , 199 (5th Cir. 2011);
    United States v. Cantu, 
    167 F.3d 198
    , 203 (5th Cir. 1999). This Court has
    previously held that it was not an abuse of discretion to exclude evidence offered
    on a very similar theory. See United States v. Arledge, 
    553 F.3d 881
    , 894 (5th
    Cir. 2008) (excluding evidence in fraud case showing that similarly situated
    third parties committed similar acts because it had little or no bearing on
    whether defendant acted with fraudulent intent).            The industry practice
    evidence offered here has little or no bearing on whether the Defendants-
    Appellants acted with fraudulent intent. See United States v. Kahn, 
    711 F. Supp. 2d 9
    , 12 (D.D.C. 2010) (testimony about beliefs of third parties on validity
    of tax code irrelevant to determination of whether defendant acted in good faith).
    Indeed, this unrelated information posed a threat of confusing the jury and
    detracting from relevant information about the conduct of the actual parties.
    See Fed. R. Evid. 403 (stating “relevant evidence” may be excluded “if its
    probative value is substantially outweighed by a danger of . . . unfair prejudice,
    confusing the issues, [or] misleading the jury . . .”). Thus, we hold that it was not
    an abuse of discretion to exclude this testimony.
    Second, the Defendants-Appellants challenge the district court’s admission
    of the government’s expert, Matthew O’Loughlin. The admission of expert
    evidence is also reviewed “for abuse of discretion; however, evidentiary rulings
    43
    Case: 09-20871        Document: 00511861304          Page: 44     Date Filed: 05/18/2012
    No. 09-20871
    are subjected to heightened scrutiny in criminal cases.” United States v. John,
    
    597 F.3d 263
    , 274 (5th Cir. 2010). “Federal Rule of Evidence 702 provides that
    testimony by a qualified expert is admissible if (1) it will assist the trier of fact;
    (2) it is based upon sufficient facts or data; (3) the testimony is a product of
    reliable methods; and (4) the witness has applied those principles reliably to the
    facts.” 
    Id.
    The Fifth Circuit has already upheld the admission of O’Loughlin’s expert
    testimony in nearly identical circumstances. See Valencia, 
    600 F.3d at 401
    ,
    420–29.     The Defendants-Appellants’ attempts to distinguish Valencia are
    unavailing. The Defendants-Appellants argue that here, unlike in Valencia,
    O’Loughlin expressly “rejected” the publishers’ testimony about their editorial
    process. Valencia, however, upheld O’Loughlin’s testimony because it was not
    simply an attack on the credibility of the publishers; his testimony also provided
    a conclusion grounded in analysis. See 
    600 F.3d at 427
    . The Defendants-
    Appellants do not argue O’Loughlin’s testimony was not so grounded here, and
    his disagreement with the publishers did not render his testimony inadmissable.
    Cf. United States v. Whitted, 
    11 F.3d 782
    , 786–87 (8th Cir. 1993) (holding experts
    could not testify about credibility of fact witnesses).                    Accordingly, the
    Defendants-Appellants fail to show the district court abused its discretion when
    it admitted the testimony of O’Loughlin.27
    Third, Defendant-Appellant Walton argues that the district court erred by
    failing to order the government to immunize Don Guilbault, a physical gas
    trader on the same desk as Dean. In particular, Walton argues, first, that the
    27
    The Defendants-Appellants’ half-hearted attack on O’Loughlin’s qualification is also
    unavailing. The Defendants-Appellants, along with failing to raise this objection to the district
    court, cite no authority to show that work in the relevant field is a necessary qualification for
    expert testimony. Presumably, their failure stems from the fact that any such authority would
    contradict the terms of Rule 702, which allows an expert to be qualified by “knowledge, skill
    experience, training or education.” See Fed. R. Evid. 702 (emphasis added).
    44

    No. 09-20871
    district court should have denied Guilbault’s invocation of his Fifth Amendment
    right because he had already plead guilty to the relevant crimes and the statute
    of limitations had expired on any others, and, second, that the district court
    should have either granted Guilbault immunity or compelled the government to
    do so. As Walton shows error on neither ground, his argument fails.
    Guilbault worked on El Paso during the relevant times, and, on October
    5, 2004, he plead guilty to violating the CEA by submitting false reports to
    Inside FERC and NGI.        At the time of the Defendants-Appellants’ trial,
    Guilbault had not been sentenced because the government had sought to delay
    sentencing to ensure Guilbault’s continued corporation in its prosecutions. On
    June 2, 2005, Guilbault was interviewed by government agents. According to a
    summary of the interview, Guilbault stated that, while Brooks told Guilbault to
    “get with” Walton, Walton told Guilbault that he did not need to show Walton
    his trades, and that Walton did not otherwise tell Guilbault what to report.
    Walton subpoenaed Guilbault to appear at trial, and informed the
    government of the subpoena the day before Guilbault was to appear. That night,
    one of the members of the prosecution called Guibault’s attorney to ask if
    Guilbault would indeed testify. The next morning at trial, Guilbault’s attorney
    informed the court that Guilbault would invoke his Fifth Amendment right
    against self-incrimination. Guilbault’s attorney told the court that the decision
    has been Guilbault’s alone to make. Guilbault’s attorney further explained that,
    while Guilbault had been on a list of possible government witnesses, no decision
    had been made previously about whether he would be called. Prosecutors then
    informed the court that they did not intend to call Guilbault because they had
    concerns about Guilbault’s truthfulness, and pointed to inconsistences between
    Guilbault’s 2005 interview and previous statements, as well as other instances
    that cast doubt on his credibility. Walton thereafter moved to compel Guilbault
    45
    Case: 09-20871    Document: 00511861304     Page: 46    Date Filed: 05/18/2012
    No. 09-20871
    to testify, to compel the government to grant Guilbault immunity, or to admit a
    summary of the 2005 interview. The district court denied each request.
    “A district court’s decision to exclude a witnesses’s testimony based on an
    invocation of the witnesses’s Fifth Amendment privilege is reviewed for an abuse
    of discretion.” United States v. Mares, 
    402 F.3d 511
    , 514 (5th Cir. 2005).
    “Although the trial court’s discretion is not unlimited, it must enjoy wide
    discretion in resolving a self-incrimination claim.” United States v. Van Deveer,
    
    577 F.2d 1016
    , 1017 (5th Cir. 1978) (per curiam). “Generally, an abuse of
    discretion only occurs where no reasonable person could take the view adopted
    by the trial court.” Whitehead v. Food Max of Miss., Inc., 
    332 F.3d 796
    , 803 (5th
    Cir. 2003) (quotation omitted & emphasis in original).
    Here, although Guilbault had plead guilty to violating the CEA, he had not
    yet been sentenced, and Walton’s questions sought information related to those
    crimes. The Fifth Amendment right against self-incrimination only extinguishes
    once “the sentence has been fixed and the judgment of conviction has become
    final.” Mitchell v. United States, 
    526 U.S. 314
    , 326 (1999) (“Where the sentence
    has not yet been imposed a defendant may have a legitimate fear of adverse
    consequences from further testimony.”). Accordingly, the district court did not
    err in finding Guilbault had a legitimate fear of self-incrimination, and could be
    excused from testifying.
    With regard to immunity, this Court has held that “[d]istrict [c]ourts have
    no inherent power to grant immunity.” United States v. Follin, 
    979 F.2d 369
    ,
    374 (5th Cir. 1992). “A district court may not grant immunity simply because
    a witness has essential exculpatory evidence unavailable from other sources.”
    
    Id.
     (citing United States v. Thevis, 
    665 F.2d 616
    , 638–41 (5th Cir. 1982)). At
    most, this Court has left open the possibility that immunity may be necessary
    46
    Case: 09-20871       Document: 00511861304          Page: 47      Date Filed: 05/18/2012
    No. 09-20871
    to stem government abuse. See Thevis, 
    665 F.2d at 641
    .28 Here, however, the
    district court found no abuse, and Walton has failed to show error in that
    determination.
    Walton’s sole evidence showing an abuse by the government is the
    government’s continuances of Guilbault’s sentencing, a single call by a
    prosecutor to Guilbault after Walton subpoenaed him to testify, and the
    purported inconsistency in the government’s maintaining Guilbault as a possible
    witness and its statements on January 24, 2008 that it had concerns about
    Guilbault’s truthfulness. Guilbault’s attorney, however, informed the court that
    Guilbault’s decision to invoke the Fifth Amendment was his own. Further, the
    prosecutor’s call the night before was explained as an inquiry to determine
    whether the government would need to prepare to cross-examine Guilbault, a
    task that would be need to be completed that night as Walton only informed the
    government about the subpoena that day.                  And the government’s proffer
    demonstrated a reasonable basis for it to doubt Guilbault’s veracity. In light of
    such facts, Walton fails to show the district court erred in accepting the
    prosecution’s, and Guilbault’s attorney’s, view of the facts.29
    28
    Walton’s citation to out-of-circuit precedent to argue that government misconduct is
    not a necessary prerequisite is unavailing in light of Thevis. See Thevis, 
    665 F.2d at
    639–41
    (declining to follow Gov’t of Virgin Islands v. Smith, 
    615 F.2d 964
    , 974 (3d Cir. 1980)).
    Moreover, even if this Court could consider such authority, Walton fails to show immunity was
    justified under it. Walton fails to show that Guilbault’s exclusion skewed the evidence in the
    government’s favor. Although Guilbault could have testified that Walton never asked him to
    send false trades, such testimony hardly contradicts O’Toole’s and Dean’s testimony that
    Walton provided them with his positions. See United States v. Straub, 
    538 F.3d 1147
    , 1156–57
    (9th Cir. 2008) (finding exculpatory evidence must “directly contradict[]” admitted evidence
    to warrant immunity). Further, in cross-examination of O’Toole, Walton introduced his theory
    that he did not always provide the traders with his positions, and that he did not ask to review
    their submissions to the publications. See United States v. Ebbers, 
    458 F.3d 110
    , 119 (2d Cir.
    2006) (finding exculpatory evidence must not be “cumulative”). Guilbault’s testimony would
    not have been materially more exculpatory.
    29
    Waltons’ argument, made only in passing and citing no support, that the interview
    memorandum should have been introduced as evidence is also unavailing. The memorandum

    No. 09-20871
    F. Sentencing
    Lastly, the Defendants-Appellants raise a number of challenges to the
    calculation of their Sentencing Guidelines’ sentences.                   In particular, the
    Defendants-Appellants challenge the burden of proof born by the government
    and the calculation of their Guidelines range.
    We review the district court’s legal interpretation of the Sentencing
    Guidelines de novo and factual findings for clear error. See United States v.
    Murray, 
    648 F.3d 251
    , 254 (5th Cir. 2011). A factual finding is clearly erroneous
    only if, based on the entirety of the evidence, the reviewing court is left with the
    definite and firm conviction that a mistake has been made. United States v.
    Valdez, 
    453 F.3d 252
    , 262 (5th Cir. 2006). A factual finding is not clearly
    erroneous if it is plausible in light of the entire record. 
    Id.
     Because the Court
    finds Defendants-Appellants’ arguments unavailing, we affirm the sentence.
    1.     Burden of Proof
    The Defendants-Appellants first argue that the government should have
    been required to prove the loss caused by their fraud with clear and convincing
    evidence. The Presentence Report (“PSR”) provided for increases of eighteen and
    twenty-levels for the Defendants-Appellants due to the calculated loss, which
    was the largest contributing factor to the Defendants-Appellants’ offense levels.30
    is hearsay. See United States v. Moore, 
    651 F.3d 30
    , 83 (D.C. Cir. 2011) (finding witness’s
    prior confessions hearsay under Federal Rule of Evidence 804(b)(3)). Guilbault’s invocation
    of the Fifth Amendment rendered him unavailable. See 
    id.
     However, none of the exceptions
    to hearsay apply. The portion of the statement Walton sought to introduce was not against
    Guilbault’s interest because it was exculpatory. See Fed. R. Evid. 804(b)(3). And the fact that
    it was contradicted by an earlier statement by Guilbault tends to show it does not “ha[ve]
    equivalent circumstantial guarantees of trustworthiness.” See Fed. R. Evid. 807; Moore, 
    651 F.3d at 83
     (finding witness’s prior contradictions rendered hearsay statements untrustworthy).
    Accordingly, Walton showed no error in the district court’s decision to exclude the interview
    summary.
    30
    The calculated loss resulted in a twenty-level increase for Brooks, increasing his
    offense level from fifteen to thirty-five, and resulted in an eighteen-level increase for Walton
    and Phillips, increasing their offense levels from fifteen to thirty-three.
    48
    Case: 09-20871        Document: 00511861304           Page: 49     Date Filed: 05/18/2012
    No. 09-20871
    They argue that, because of the significant effect of the loss, due process requires
    that the government prove the loss by more than a mere preponderance.
    “[A]s a general matter, the burden of proof at sentencing is by a
    preponderance of the evidence.” United States v. Mergerson, 
    4 F.3d 337
    , 343 (5th
    Cir. 1993). The Fifth Circuit has stated in dicta, however, that “there may be
    certain cases where a sentencing fact is a ‘tail that wags the dog of the
    substantive offense,’ and might arguably require a finding beyond a reasonable
    doubt.” 
    Id. at 344
     (quoting McMillan v. Pennsylvania, 
    477 U.S. 79
    , 88 (1986)
    (rejecting petitioner’s argument that visible possession of firearm enhancement
    was element of crime required to be proved beyond a reasonable doubt)).
    Nevertheless the Fifth Circuit has never required such a heightened burden.
    See 
    id.
     at 344–45 (finding a preponderance standard was sufficient where life
    sentence was within range both prior to and after enhancement); United States
    v. Coleman, 290 F. App’x 684, 685 (5th Cir. 2008) (per curiam) (finding
    sentencing judge did not commit plain error where judge applied preponderance
    standard to sentencing). Indeed, nearly all of our fellow circuits have rejected
    the need to apply a heightened standard in light of the advisory nature of the
    Guidelines.31
    31
    See United States v. Villareal-Amarillas, 
    562 F.3d 892
    , 894–98 & n.3 (8th Cir. 2009)
    (holding sentencing factors may be proven by preponderance; finding dicta in United States
    v. Archuleta, 
    412 F.3d 1003
    , 1007 (8th Cir. 2005), expressing otherwise was erroneous);
    United States v. Fisher, 
    502 F.3d 293
    , 308 (3d Cir. 2007) (holding preponderance sole standard
    of proof in sentencing; stating “because the Guidelines are now advisory and district judges
    are empowered to discharge their duties fully in the first instance, it is a logical impossibility
    for the ‘tail to wag the dog,’ as could occur when the Guidelines were mandatory”); United
    States v. Brika, 
    487 F.3d 450
    , 460–62 (6th Cir. 2007) (holding preponderance standard applies,
    even where judge sentenced defendant for conduct underlying charge on which jury hung);
    United States v. Reuter, 
    463 F.3d 792
    , 793 (7th Cir. 2006) (finding tail-wagging-dog concern
    rendered “academic” after Booker); but see United States v. Staten, 
    466 F.3d 708
    , 717–20 (9th
    Cir. 2008) (finding due process required proof by clear and convincing evidence where
    enhancement increased offense level fifteen levels and effectively doubled defendant’s
    sentence; holding United States v. Booker, 
    543 U.S. 220
     (2005), which rendered Sentencing
    Guidelines advisory, did not require departure from earlier precedent).

    No. 09-20871
    We need not decide at this time that a heightened burden is never
    required. While the Defendants-Appellants’ enhancements are significant,
    accounting for more than fifty percent of their offense levels, and increasing
    their recommended sentence range from 18-to-24 months to 135-to-168 or 168-
    to-210 months, this Court has held a similar enhancement did not require a
    heightened burden of proof. See United States v. Carreon, 
    11 F.3d 1225
    , 1240
    (5th Cir. 1994) (holding enhancement in recommended sentence from six years
    to twenty years did not require proof beyond a preponderance).32 Accordingly,
    we find that a heightened burden or proof, even if required by due process in
    certain situations, is not appropriate here, and the district court did not err in
    refusing to apply one.
    2.     Calculation of Guidelines Range
    The Defendants-Appellants assert a number of errors in the calculation of
    their Sentencing Guidelines. In particular, the Defendants-Appellants challenge
    the district court’s calculation of loss, its calculation of the number of victims of
    that loss, and its finding that the Defendant-Appellants obstructed justice.
    Turning first to the calculation of loss, “[w]e review de novo the district
    court’s method for determining loss, while clear error applies to the background
    factual findings that determine whether or not a particular method is
    appropriate.” Isiwele, 
    635 F.3d at 202
    . “[A] district court need only make a
    reasonable estimate of loss, and, ‘because the sentencing judge is in a unique
    position to assess the evidence and estimate the loss . . . the court’s loss
    determination is entitled to appropriate deference.’” Murray, 
    648 F.3d at 254
    (ellipsis in original) (quoting United States v. Goss, 
    549 F.3d 1013
     (5th Cir.
    2008)).
    32
    See also United States v. Vittek, 228 F. App’x 469, 475–76 & n. 23 (5th Cir. 2007) (per
    curiam) (finding increase in recommend sentencing range from 51-to-63 months to sentence
    of 168 months did not require heightened standard of proof).
    50
    Case: 09-20871        Document: 00511861304        Page: 51     Date Filed: 05/18/2012
    No. 09-20871
    The Defendants-Appellants fail to show that the district court’s method for
    determining loss was erroneous. The district court, adopting the method used
    in the PSRs, relied on O’Loughlin’s calculations about the effect of the false
    reports on the published index prices, and El Paso’s own calculations, in its
    “Basis Summaries,” about its “exposure” to changes in those index prices. The
    various losses were then attributed to each Defendant-Appellant based on his
    responsibility for the various reports. The method provided a “reasonable
    estimate,” and, indeed, a conservative estimate, of the loss caused by the
    Defendants-Appellants’ fraudulent scheme.33               Although the editors of the
    industry publications used some editorial discretion to determine what index
    price to publish, and did not rotely publish the volume-weighted average of the
    reported trades, O’Loughlin demonstrated that the published price and the
    volume-weighted average of the reported trades was identical eighty percent of
    the time, and a strong correlation between the two was observable for the
    remainder of the trades.34 Admittedly, as Hume observed over 250 years ago,
    one can never know with certainty that one event is caused by another.35
    Unfortunately for the Defendants-Appellants, the law does not require such
    absolute certainty.36
    33
    The estimate did not include any loss caused to counterparties who purchased
    natural gas from El Paso at index price, or those parties who did not contract with El Paso,
    but nevertheless payed an inflated price for natural gas due to Defendants-Appellants actions.
    34
    Indeed, the PSRs excluded gains where the published index prices was different than
    the volume weighted average would have dictated.
    35
    See David Hume, An Enquiry Concerning Human Understanding (1748).
    36
    Moreover, loss may be measured not only by the actual loss caused by a defendants’
    actions, but by the loss the defendants intended to cause. See U.S. Sentencing Guidelines
    Manual § 2B1.1 cmt. n.2(A) (2001). Loss is the “greater of the actual loss or intended loss.”
    See id. Thus, even if the Court were to conclude O’Loughlin’s testimony was insufficient to
    demonstrate the actual influence the VWA had on the published indexes, such difference was
    a fair approximation of the change the Defendants-Appellants intended to have on the
    published indexes.

    Nor does the Defendants-Appellants’ challenge to the use of the use of El
    Paso’s Basis Summaries fare better. As the record shows, the summaries were
    created so that El Paso could determine its exposure to changes in the various
    index prices. El Paso entered into a trade to buy or sell natural gas at some
    price at a certain hub. That contract had value so long as there was some
    difference between the specified price and the market price for natural gas at the
    hub at the time of the contract’s execution. For example, a contract to buy a unit
    of natural gas at $5 next month would gain value if the price of natural gas at
    the hub increased to $6: the contract would allow the holder to net a $1 profit by
    buying the gas at $5 and selling it at $6.37 Conversely, the contract would
    negatively impact the company if the price of natural gas fell to $4, as the
    company would be required to spend $5 on the natural gas and then could only
    sell it at a $1 loss.38 El Paso’s basis summary charts aggregated these various
    risks, and thus reflected the inflation or deflation in value of El Paso’s futures
    contracts.
    While the Defendants-Appellants are correct that these charts did not
    necessarily reflect the flow of cash,39 they identify no legal authority suggesting
    that the Sentencing Guidelines are incapable of taking into account the losses
    and gains described above. The Sentencing Guidelines state that “fair market
    value of the property unlawfully taken” shall be used to determine the value of
    loss. See U.S. Sentencing Guidelines Manual § 2B1.1 cmt. n. 2(C)(i) (2001).
    Here, the Defendants-Appellants’ scheme drove up the market price of their
    37
    As discussed above, these transactions rarely resulted in the actual transfer of
    physical gas, but were instead resolved financially.
    38
    This also explains why trades that specified the price to be paid as the published
    index price did not create this type of risk: any variations in the market price would be
    reflected in the price at which El Paso would have to buy or sell.
    39
    Although it is difficult to believe that the value of these contracts were not converted
    to cash, or some other asset, at any point during the Defendants-Appellants’ two-year scheme.

    contracts, which necessarily drove down the market price of their counterparties’
    contracts.40 Thus, the basis summaries’ calculation of the increase in the value
    of El Paso’s futures contracts provides a reasonable basis from which to infer the
    counterparties’ loss in market value to their contracts.
    Moreover, in contrast to the Defendants-Appellants’ protests, the method
    employed by the district court provided a “realistic, economic approach” to
    determining the loss caused by their fraud. See United States v. Olis, 
    429 F.3d 540
    , 546 (5th Cir. 2005) (quotation omitted). Unlike the typical valuation of
    damages in a securities fraud scheme, where the effect of the fraud must be
    inferred from the changes in the market price of the security and where,
    consequently, external forces on that price must be accounted, see, e.g., 
    id.
     at
    546–48, the method employed by the district court directly measured the loss.
    As described above, the district court relied on the government’s expert’s
    conclusion that the false trades move the various index prices by definite
    amounts, and the company’s calculations about the effect of such moves on the
    value of its assets. With such a method, there is no need to account for external
    factors that may have also increased or decreased the value of the futures
    contracts.
    Next, the Defendants-Appellants challenge the calculation used to
    determine the number of victims of their fraud. Each of the Defendants-
    Appellants received a four-point enhancement to their offense level due to the
    district court’s finding that their scheme involved fifty or more victims. See U.S.
    Sentencing Guideline § 2B1.1(b)(2)(B). In light of the entire record, the district
    40
    This can be seen from the example above. If El Paso has a contract to buy gas at $5,
    then the counterparty has a contract to sell gas at $5. If the Defendants-Appellants could
    fraudulent raise the market price to $6, their contract would be worth $1, while the
    counterparty’s contract would have a negative value of $1. In essence, the Defendants-
    Appellants would have stolen $1 from their counterparty by fraudulently shifting the market
    value of the trade. Further, if the counterparty was hedged, it would merely shift the loss to
    yet another third party.

    Case: 09-20871       Document: 00511861304          Page: 54     Date Filed: 05/18/2012

    court’s finding is not clearly erroneous. The record includes backup for the Basis
    Summaries reports that list the details of the various financial trades that went
    into those calculations. Just one of those backup spreadsheets, showing the
    trades for a single hub in a single month, shows in excess of fifty counterparties
    to El Paso’s futures trades—the counterparties who would have seen the value
    of their contracts artificially lowered by the Defendants-Appellants’ false
    statements. Accordingly, Defendants-Appellants fail to show error in the district
    court’s finding that their scheme, which occurred over at least two years and
    covered multiple hubs, involved more than fifty victims.
    Lastly, the Defendants-Appellants challenge the two-point enhancement
    they received as a result of the district court’s finding that they obstructed
    justice. In particular, the Defendants-Appellants argue that the district court
    improperly found that they provided materially false information to the
    investigating government officials because they mislead the individuals involved
    in El Paso’s internal investigation.          The Defendants-Appellants argue they
    cannot be found to have obstructed the investigation because, (1) their
    statements occurred before any government investigation started, (2) their false
    statements were not made directly to government agents, and (3) their false
    statements did not actually impede the investigation.
    The relevant Sentencing Guidelines allow for an enhancement where:
    (A) the defendant willfully obstructed or impeded, or attempted to
    obstruct or impede, the administration of justice during the course
    of an investigation, prosecution, or sentencing of the instant offense
    of conviction, and (B) the obstructive conduct related to (i) the
    defendant’s offense of conviction and any relevant conduct; or (ii) a
    closely related offense . . . .
    See U.S. Sentencing Guideline § 3C1.1 (2001).41
    41
    The Guidelines provide a non-exhaustive list of examples of such conduct, including
    “destroying or concealing or directing or procuring another to destroy or conceal evidence that

    No. 09-20871
    First, with regard to Brooks, the district court found, in addition to his
    false statements, that in or about May of 2002 he destroyed or ordered another
    person to destroy material evidence when he ordered an El Paso employee to
    shred records related to reports to an industry newsletter. As noted in the PSR,
    and unchallenged by the Defendants-Appellants,42 such conduct occurred during
    the course of a state investigation into false reporting at El Paso of which Brooks
    had knowledge.43         Brooks’ sole challenge to the district court’s finding of
    obstruction for his destruction of documents was his conduct was innocent.
    Looking to the record as a whole, the district court’s finding to the contrary was
    not implausible. Accordingly, Brooks fails to show such a finding is clearly
    is material to an official investigation or judicial proceeding,” and “providing a materially false
    statement to a law enforcement officer that significantly obstructed or impeded the official
    investigation or prosecution of the instant offense.” See id. at cmt. n.4 (d), (g). The Guidelines
    further provide examples of non-covered conduct, such as “making false statements, not under
    oath, to law enforcement officers, unless Application Note 3(g) above applies,” and “providing
    incomplete or misleading information, not amounting to a material falsehood in respect to a
    presentence investigation.” See id. at cmt. n. 5(b), (c). A 2006 amendment to the Guidelines
    allows consideration of pre-investigation conduct. See United States v. Alexander, 
    602 F.3d 639
    , 642 n.3 (5th Cir. 2010).
    42
    The district court adopted the factual findings of the PSR. “[I]f no relevant affidavits
    or other evidence is submitted to rebut the information contained in the [presentence report],
    the court is free to adopt its findings without further inquiry or explanation.” United States
    v. Vital, 
    68 F.3d 114
    , 121 (5th Cir. 1995).
    43
    While the pre-2007 Guidelines required conduct to occur during the course of an
    investigation into the conduct at issue, they did not require the investigation to be led by the
    federal government, or to be a criminal investigation, so long as it was led by government
    officials. See United States v. Fiore, 
    381 F.3d 89
    , 94 (2d Cir. 2004) (finding SEC civil
    investigation into conduct giving rise to later criminal charge sufficient to render obstructive
    conduct relevant for sentencing enhancement); United States v. McGovern, 
    329 F.3d 247
    , 252
    (1st Cir. 2003) (finding Medicaid & Medicare civil investigation sufficient to allow for
    obstruction enhancement); see also United States v. Upchurch, 88 F. App’x 794, 795–96 (5th
    Cir. 2004) (per curiam) (finding state investigation into conduct at issue sufficient to trigger
    obstruction enhancement). While the Defendants-Appellants assert the earlier investigation
    was into wash trading, the record indicates the investigation also covered false reporting, and,
    accordingly, the district court’s conclusion was not implausible.
    55
    Case: 09-20871       Document: 00511861304         Page: 56     Date Filed: 05/18/2012
    No. 09-20871
    erroneous, and, in light of such a finding, the district court did not err in
    providing a two-point enhancement.
    With regard to Phillips and Walton, the PSRs found obstruction based on
    their statements to El Paso’s legal counsel and independent investigators during
    the company’s investigation arising from inquiries by the CFTC, the Federal
    Energy Regulatory Commission, and the U.S. Attorney’s Office.44                         The
    Defendants-Appellants show no error in the district court’s finding that they
    made their false statements during the course of the investigations. Similarly,
    they show no error in the district court’s finding the Phillips’s and Walton’s
    statements were not made in ignorance of the investigations and were not “the
    result of a spur of the moment decision.” See United States v. Greer, 
    158 F.3d 228
    , 235 (5th Cir. 1998) (finding obstruction limited to “egregiously wrongful
    behavior whose execution requires a significant amount of planning and
    presents an inherently high risk that justice will in fact be obstructed”).
    Further, although the statements were not made directly to government officials,
    the district court’s finding that they were made with intent to be communicated
    to government officials, and thus to impede the investigation into their wrong-
    doing, was not implausible. See U.S. Sentencing Guidelines Manual §3C1.1 cmt.
    n.9 (providing obstruction may be “induced, procured, or willfully caused”); see
    also United States v. Aguilar, 
    515 US 593
    , 601 (1995) (holding, to secure
    conviction for obstruction of justice charge, government must show defendant
    “knew that his false statement would be provided to the grand jury”).
    Finally, the Defendants-Appellants fail to show error in the district court’s
    adoption of the PSRs’ finding that their false statements significantly impeded
    44
    The PSR also found Brooks obstructed the investigation based on his statements to
    El Paso’s legal counsel and internal investigation. Nonetheless, because the district court’s
    finding of obstruction was supported by Brooks’s destruction of evidence, the Court does not
    address Brooks’s false statements.
    56
    Case: 09-20871       Document: 00511861304          Page: 57      Date Filed: 05/18/2012
    No. 09-20871
    the investigation. False statements which significantly delay an investigation
    and prosecution, even if not successful in preventing it, may provide a sufficient
    basis for an obstruction enhancement. See United States v. Phipps, 
    319 F.3d 177
    , 191–92 (5th Cir. 2003) (holding defendant’s false identification of
    accomplice, delaying investigation, constituted obstruction). While Defendants-
    Appellants objected to the PSRs’ finding, they presented no evidence to rebut
    that finding. See Vital, 
    68 F.3d at 121
    . Consequently, the district court could
    rely on the PSRs, see 
    id.,
     and the Defendants-Appellants fail to show that the
    district court’s finding was implausible based on the record. Thus, they fail to
    show error in the obstruction enhancement.
    Accordingly, the Defendants-Appellants fail to show any error in their
    sentences.45
    CONCLUSION
    For the reasons stated above, Defendants-Appellants’ convictions and
    sentences are AFFIRMED.
    45
    The Defendants-Appellants’ additional purported error, that the district court
    erroneously treated the guidelines as presumptively reasonable, see Gall v. United States, 
    552 U.S. 38
    , 50 (2007), is without any support in the record. Indeed, the district court’s statement
    of reasons indicates that it made “an individualized assessment based on the facts presented.”
