    Before HARTZ, O’BRIEN, and HOLMES, Circuit Judges.
    HOLMES, Circuit Judge.
    Defendant-Appellant George David Gordon is a former securities attorney
    convicted of multiple criminal charges relating to his alleged participation in a
    “pump-and-dump” scheme where he, along with others, violated the federal
    securities laws by artificially inflating the value of various stocks, and then
    turning around and selling them for a substantial profit. The government also
    restrained some of his property before the indictment was handed down and
    ultimately obtained criminal forfeiture of that property. We affirm Mr. Gordon’s
    conviction and sentence, as well as the accompanying forfeiture orders.
    I. Factual and Procedural Background
    Mr. Gordon was a securities attorney in Tulsa, Oklahoma. The government
    charged that Mr. Gordon and Richard Clark, 1 a Tulsa businessman, engaged in a
    “pump-and-dump” scheme. 2 As part of their scheme, Messrs. Gordon and Clark,
    1
    Mr. Clark is the subject of a related appeal arising from his
    convictions in the same scheme. See United States v. Clark, No. 10-5152.
    2
    In the indictment, the government describes pump-and-dump
    schemes as follows:
    A pump and dump scheme involves the artificial manipulation of
    the price and volume of a particular stock in order to later sell
    that stock at an artificially inflated price. Generally, the
    perpetrators of a pump and dump scheme obtain control over a
    substantial portion of free trading shares of the company. Free
    trading shares are shares of stock that the owner can trade
    without restriction on a national exchange, e.g., the New York
    Stock Exchange or NASDAQ, or are traded in the
    over-the-counter market via the Pink Sheets. To obtain the free
    trading shares, the perpetrators may orchestrate a reverse merger,
    which occurs when a privately held company with no publicly
    traded stock merges with a publicly listed shell company that has
    (continued...)
    -2-
    along with other alleged co-conspirators, “acquired millions of shares in ‘penny
    stock’ companies[,] . . . used false and backdated documents to make their shares
    publicly tradeable[,] . . . [and] coordinated trading among themselves and
    nominees they controlled to create the false appearance of an active market for
    the stock[s].” Aplee. Br. at 3.
    The government further claimed that the conspirators initiated false and
    misleading advertising campaigns to promote the stocks, sold the stocks through
    “an array of bank accounts and nominee[s],” and engaged in a subsequent cover-
    up to conceal their conduct from the Securities and Exchange Commission
    2
    (...continued)
    no assets or revenue but has stock available for public trading,
    resulting in a public company. The pump usually involves
    artificially inflating a company’s stock price by engaging in
    coordinated trading of the stock in order to create the appearance
    of a more active market for that stock. The pump also usually
    involves disseminating false and misleading promotional
    materials—unsolicited advertisements touting a particular stock
    and encouraging others to purchase the stock, which are often
    sent to millions of recipients by fax or email “blasts.” After
    pumping the stock, the perpetrators dump their shares, meaning they
    sell large volumes of the shares that they own and control to
    unsuspecting investors. The dumping often occurs soon after the
    dissemination of the promotional materials touting the particular
    company. The perpetrators of a pump and dump scheme will often
    “park” their shares by depositing or transferring them into different
    accounts, including nominees ’ accounts, and then trade the
    manipulated stock using the different accounts in order to conceal
    their trading activity.

    (“SEC”). Id. at 3–4.
    The scheme can be traced back to 2004 when Mr. Gordon began dealing
    with Mark Lindberg and Joshua Lankford, two Dallas stock promoters (also
    alleged members of the conspiracy). Through a sequence of transactions, Mr.
    Gordon assisted Mr. Lindberg, Mr. Lankford, and others in, inter alia,
    establishing and promoting the stock of numerous companies. Transactions
    involving three companies headline the government’s charges: specifically,
    National Storm Management (“National Storm”), Deep Rock Oil & Gas (“Deep
    Rock”), and Global Beverage Company (“Global Beverage”). The government
    also alleged that Mr. Gordon fraudulently obtained free-trading shares of
    International Power Group (“IPG”). We briefly discuss the material facts relevant
    to each company below. 3
    A.    National Storm
    National Storm was a roofing and siding company in Illinois with annual
    revenues of around $8 million. Mr. Gordon and Mr. Lindberg met with National
    3
    The entirety of the indictment charged Mr. Gordon with: conspiracy
    (Count 1), in violation of 
    18 U.S.C. § 371
    ; wire fraud (Counts 2–10, 23), in
    violation of 
    18 U.S.C. §§ 1343
     and 2(a); securities fraud (Counts 11–15), in
    violation of 15 U.S.C. §§ 78j(b), 78ff and 
    17 C.F.R. § 240
    .10b-5, 
    18 U.S.C. § 2
    (a); money laundering (Counts 16–21), in violation of 
    18 U.S.C. §§ 1957
    (a)
    and 2(a); making a false statement to a government official (Count 22), in
    violation of 
    18 U.S.C. § 1001
    ; and knowingly corrupting, or attempting to
    corrupt, an official proceeding relating to the government’s forfeiture attempts
    (Count 24), in violation of 
    18 U.S.C. § 1512
    (c)(2).

    Storm’s president in 2005 to discuss financing options. The parties agreed to take
    the company public. In pursuit of that goal, Mr. Gordon and an associate (New
    York businessman Richard Singer) arranged for a merger between National Storm
    and The 18th Letter—a public “shell company . . . that had been incorporated and
    had issued stock in 2002.” Aplt. Opening Br. at 9.
    Mr. Gordon forwarded to Mr. Singer a legal opinion letter pursuant to SEC
    Rule 144, signed by an associate attorney, Robert Bertsch, stating that The 18th
    Letter’s shares were freely tradeable under Rule 144’s criteria because the shares
    had been purchased by the respective owners two years ago. See 
    17 C.F.R. § 230.144
    (k) (“Rule 144”) (2005) (“The requirements of paragraphs (c), (e), (f)
    and (h) of this section shall not apply to restricted securities sold . . . [by] a
    person who is not an affiliate of the issuer at the time of the sale . . . , provided a
    period of at least two years has elapsed since the later of the date the securities
    were acquired from the issuer or from an affiliate of the issuer.” (emphasis
    added)); 4 see also M & A West, 538 F.3d at 1051 (“Rule 144(k) permits a person
    who is not an affiliate of the issuer . . . to sell restricted securities without
    complying with certain requirements after they have held the securities for a
    period of two years.” (footnote omitted)).
    4
    “Rule 144(k) has since been repealed and replaced by Rule 144(b),
    which replaced the two-year holding period of Rule 144(k) with a one-year
    holding period.” SEC v. M & A West, Inc., 
    538 F.3d 1043
    , 1046 n.1 (9th Cir.
    2008).

    Mr. Singer testified that because he was the only shareholder in The 18th
    Letter, Mr. Gordon instructed him to “offer some friends a thousand dollars each
    to falsely claim that they were shareholders.” Aplee. Br. at 6. Mr. Gordon’s
    office transmitted to Mr. Singer “backdated corporate records . . . that purported
    to memorialize Singers’ [sic] friends’ purchase of shares two years
    previously”—i.e., seemingly with the aim of satisfying Rule 144’s requirements.
    Id.; see R., Vol. VIII, at 1494–98 (Trial Test. of Richard Singer, dated Apr. 14,
    2010) (“[The documents] were backdated to show that the shareholders owned the
    stock longer than they actually did, so upon becoming a public company those
    shares would be freely tradable to sell in the market.”).
    The opinion letter was transmitted to a transfer agent so that the shares at
    issue could be traded publicly on an “over-the-counter” (“OTC”) market. See
    generally Black’s Law Dictionary 1214 (9th ed. 2009) (defining “over-the-counter
    market” as “[t]he market for securities that are not traded on an organized
    exchange”). The merged company consisted of six million freely-tradeable
    shares—or 15% of the total shares. National Storm’s president held the
    remaining interest in the form of restricted shares (i.e., non-trading shares).
    In 2005, several storms pelted the Gulf of Mexico, causing “severe
    damage” throughout the Southern states. Aplt. Opening Br. at 6. Because
    National Storm was a building company, Messrs. Gordon, Lindberg and Lankford
    wanted to take advantage of the potential for increased share performance, so they
    -6-
    employed a stock promoter named Dean Sheptycki (a charged co-conspirator)
    “who could write and send . . . millions of fax advertisements each day about a
    company.” Id. at 10. A “fax blast” campaign was initiated subsequently;
    thousands of faxes were sent out touting strong market expectations for National
    Storm’s future growth. A similar “e-mail blast” campaign followed.
    The distributed material was misleading in many ways. For instance, an
    August 31, 2005, fax represented that “Wall Street expectations” for the
    company’s growth were “207% now” and “450% in the next 12 months”—this,
    despite the fact that no Wall Street “analysts” were covering the company. Aplee.
    Br. at 7 (citation omitted) (internal quotation marks omitted); see also Aplt.
    Addendum, ex. 4 (Nat’l Storm Fax Advertisement, dated Aug. 31, 2005).
    Evidence also was introduced at trial that the faxes included misleading
    statements regarding the source of the information in order to “conceal the fact
    that the blast had been prepared by Sheptycki, reviewed by Gordon, and paid for
    from Gordon’s client trust account.” Aplee. Br. at 8; see also R., Vol. VIII, at
    3049–50 (Trial Test. of Mark Lindberg, dated Apr. 6, 2010) (noting that a
    marketing company included in the fax blast disclosures actually had no
    involvement with their dissemination, and that a statement suggesting that non-
    affiliated shareholders paid for the advertisements was untrue). Similarly, one
    mass e-mail that contained information regarding National Storm’s purported
    significant expected growth referred readers to the SEC’s website for investor
    -7-
    information. But, because National Storm was a so-called “Pink Sheet” OTC
    company, it was not required to file periodic reports with the SEC. See generally
    SEC v. Whittemore, 
    659 F.3d 1
    , 5 (D.C. Cir. 2011) (describing the Pink Sheet
    system as “a trading system that lists small companies that do not meet the
    requirements of the major stock exchanges”); SEC v. Platforms Wireless Int’l
    Corp., 
    617 F.3d 1072
    , 1081 (9th Cir. 2010) (noting that the defendant’s “stock
    has been traded on the Pink Sheets, now known as Pink Quote, an inter-dealer
    electronic quotation and trading system for registered and unregistered
    securities”); Black’s Law Dictionary 1265 (defining “pink sheet” as “[a] daily
    publication listing over-the-counter stocks, their market-makers, and their
    prices”); R., Vol. I, at 53 (describing “Pink Sheets” as “a quotation service for
    over-the-counter stocks”).
    Throughout the advertising campaign, Mr. Gordon, along with other co-
    conspirators, including Mr. Lindberg, used various “nominee” accounts to
    disguise ownership of National Storm shares and coordinate trading. National
    Storm’s stock began to rise. As the prices rose, the conspirators began selling
    their shares. Ultimately, the conspirators made more than $5 million from the
    manipulation of National Storm.
    B.    Deep Rock
    The conspirators conducted another promotion, this time of Deep Rock, a
    -8-
    Tulsa-based oil company. See Aplt. Opening Br. at 12 (“The rise in natural gas
    prices during the early part of 2005 caused Lindberg to want to do a similar
    promotion with Deep Rock . . . .”). Mr. Clark had held a majority of the “non-
    insider” shares of Deep Rock for many years. The government presented
    testimony that, similar to what had occurred with National Storm, Mr. Gordon
    arranged for Mr. Clark’s shares to be transferred to various nominees in order to
    disguise their ownership. See R., Vol. VIII, at 3138–39 (noting that shares were
    “parked” with others in order “to not disclose who actually control[led] all the
    shares”). Mr. Gordon prepared an opinion letter stating that the nominees had
    fulfilled Rule 144’s requirements in order for the stock to be assigned a symbol
    for public trading.
    The conspirators began coordinated trading in Deep Rock stock, some of
    which occurred via separate nominee accounts. See 
    id. at 3140
     (discussing how
    the conspirators were able to “prime” Deep Rock stock—i.e., create the
    appearance of high-volume trading before promotions began). In September
    2005, they sent out a series of fax and e-mail blasts hyping Deep Rock and
    touting its potential for astronomical profits in the wake of the chaos created by
    Hurricane Katrina and in light of rising energy prices. These faxes, like those in
    the National Storm blast, contained many misleading assertions. Also, in support
    of their efforts, the conspirators caused to be prepared certain promotional
    “magalogs”—i.e., catalogue-type brochures. Mr. Gordon personally reviewed
    -9-
    some of the promotional material. On one occasion, he responded on Deep
    Rock’s behalf to a complaint about the fax blasts, denying knowledge of the
    source of the faxes, and noting that Deep Rock “would consider joining a lawsuit
    against the perpetrators.” Aplee. Br. at 14.
    Deep Rock’s stock price rose. See Aplt. Opening Br. at 13 (noting that
    “[i]t spiked in September, 2005, then began a steady decline into 2006”). Mr.
    Gordon, along with his co-conspirators, made around $5 million in gross proceeds
    from Deep Rock sales.
    C.    Global Beverage
    In 2005, Mr. Lindberg and other co-conspirators became involved with a
    sport drink company (Rudy Beverages) founded by Rudy Ruettiger, a former
    Notre Dame athlete, and the subject of the major motion picture, Rudy. Mr.
    Ruettiger wanted to expand his business, and in the summer of 2005, conspirators,
    including Mr. Lindberg, put a plan into action to help finance the company.
    Global Beverages, a company in which certain conspirators controlled a
    substantial stake, acquired Rudy Beverages in the fall of 2005. While financing
    issues were worked out, Mr. Gordon permitted the conspirators to “park” millions
    of corporate shares in his client trust account.
    Shares of Global Beverage became publicly tradeable. And Mr. Lindberg
    and other co-conspirators devised a plan to manipulate the stock. See R., Vol.
    -10-
    VIII, at 178 (Trial Test. of Mark Lindberg, dated Apr. 7, 2010) (noting that there
    was no difference between the “manipulation of Global Beverage . . . [and]
    National Storm and Deep Rock”). 5 Mr. Lindberg testified that, as part of the plan,
    the conspirators placed many shares with nominees and began a promotional
    campaign for the company. Mr. Sheptycki composed and sent numerous faxes for
    the campaign. Further, e-mails and magalogs were transmitted. The promotional
    materials contained misleading information. See 
    id. at 215
     (noting that Mr.
    Sheptycki “made up” information regarding the source of the materials).
    The price of Global Beverage stock spiked during the end of 2005 and
    beginning of 2006, but, due in part to disappointing financials, eventually
    dropped. The conspirators, including Mr. Gordon, made roughly $25 million total
    from the manipulation of Global Beverage.
    D.    International Power Group 6
    Sometime in 2004 or 2005, Mr. Gordon approached Mr. Lindberg about
    getting a trading symbol for a private company that he and Mr. Singer had
    discovered: IPG. Mr. Gordon used a company called “Ednet”—an entity that was
    5
    Mr. Lindberg advocated for a replacement of the CEO of the
    company. Mr. Gordon recommended Mr. Clark because he was “heat-resistant,”
    see R., Vol. VIII, at 186, and would be “in with the plan,” 
    id. at 187
    . Mr. Clark
    became the CEO.
    6
    The only substantive counts in the indictment that related to the IPG
    scheme (Counts 23 and 24) concerned charges that only implicated Mr. Gordon.
    See R., Vol. I, at 76–80; see also Discussion infra.
    -11-
    controlled by his “longtime friend and business associate,” Mark White—to serve
    as a shell for a reverse merger with IPG. 
    Id. at 251
    . See generally M & A West,
    
    538 F.3d at 1046
     (“A reverse merger is a transaction in which a privately-held
    corporation acquires a publicly-traded corporation, thereby allowing the private
    corporation to transform into a publicly-traded corporation without the necessity
    of making an initial stock offering.”). Mr. Gordon prepared a Rule 144 opinion
    letter and instructed Mr. Singer to have his attorney, Robert Bertsch, sign it on his
    firm’s letterhead, “even though [Mr. Bertsch] had never communicated with the
    purported shareholders.” Aplee. Br. at 13; see R., Vol. VIII, at 1604 (answering,
    “No. Not at all,” to the question, “Did Mr. Bertsch have any conversations with
    any of [the shareholders]?”). Mr. Singer and Mr. Bertsch were given IPG shares.
    Mr. Gordon advised Mr. Lindberg’s assistant, Chasity Thompson, to
    prepare backdated corporate documents for Ednet, including bylaws and board
    meeting notes, because Mr. White ostensibly had “lost all the [original]
    documents.” R., Vol. VIII, at 907–08 (Trial Test. of Chasity Thompson, dated
    Apr. 12, 2010). After the Rule 144 opinion that Mr. Gordon drafted was
    transmitted to a transfer agent, unrestricted shares were issued. Mr. Singer
    gradually sold shares on Mr. Gordon’s behalf, and at one point in November
    2005, wire-transferred roughly $1.7 million of the proceeds to “pay off the
    mortgage on [Mr. Gordon’s] house.” Id. at 1610. The government also presented
    evidence that Mr. Singer later prepared a false, backdated document purporting to
    -12-
    memorialize a sale of IPG stock between Mr. Gordon and Mr. Singer that never
    actually took place. This document allegedly was created in an attempt to stop
    the government from obtaining forfeiture of Mr. Gordon’s home.
    E.    The Investigation and Prosecution
    In 2004, SEC official Samuel Draddy began looking into an unrelated Pink
    Sheet company that had some “unusual trading surrounding its stock and appeared
    to be the subject of a promotional campaign.” Id. at 1753 (Trial Test. of Samuel
    Draddy, dated Apr. 15, 2010). This case led to further investigations of other
    “similarly-situated issuers” with unusual trading patterns and promotional
    campaigns. Id. After taking a deeper look, investigators noticed that the
    companies under consideration revealed similar patterns where “the people
    involved owned shells, [which] were publicly-traded issuers that had no
    legitimate business purpose, . . . [and t]hey would then get private companies to
    reverse-merge into these shells so they could get publicly traded.” Id. at 1754.
    Mr. Gordon represented some of the companies and individuals involved in the
    investigations, including National Storm and Deep Rock.
    SEC investigators called Mr. Gordon on September 20, 2005. Before
    commencing the discussion, they informed Mr. Gordon that he could speak with
    counsel before answering their questions, and that he could choose whether or not
    to answer the questions as a general matter. They also informed him that “there
    -13-
    [were] potential penalties, both civil and criminal, for giving false answers to
    government officials.” Id. at 1772. During the conversation, Mr. Gordon was
    asked about, and denied any knowledge of, the source of the National Storm and
    Deep Rock promotions. 7
    In 2007, roughly two years before the indictment was filed, the government
    placed a caveat on two lots that Mr. Gordon had previously acquired as a part
    owner of the Delvest Corporation (the “Delvest lots”). See generally Black’s Law
    Dictionary 252 (defining “caveat” as “[a] warning or proviso”). Further, a caveat
    was placed on Mr. Gordon’s personal residence. The government also seized two
    of his law firm’s bank accounts. The government filed a civil forfeiture action
    against the residential property in 2007 and replaced the caveat with a lis
    pendens. Upon the response of Mr. Gordon’s wife—who was listed as the
    primary owner of the home—the government obtained a stay pending the
    resolution of its criminal investigation. When the indictment was returned in
    2009, it sought forfeiture of both the residence and the law firm accounts.
    At trial, 8 the government called various witnesses (and co-conspirators) to
    7
    Later, on Mr. Gordon’s recommendation, many of his individual
    clients involved in the transactions at issue invoked the Fifth Amendment and
    refused to testify in front of the SEC.
    8
    On March 10, 2009, the district court granted the government’s
    motion to declare the matter complex, and ordered an ends-of-justice continuance
    under the Speedy Trial Act. The court subsequently set the trial date for January
    (continued...)
    -14-
    summarize the details of the conspiracy, including Mr. Lindberg and Mr. Singer.
    Investigator Draddy also testified about the promotional campaigns and Mr.
    Gordon’s discussion with the SEC. Other witnesses were called to summarize
    volumes of documentary evidence.
    Late in the trial, the district court excused a petit juror. Specifically, after
    the government rested its case, a juror informed a court staff member that she
    wanted to serve as an alternate because her continued presence on the jury “could
    affect the outcome of the case,” R., Vol. VIII, at 2468 (Trial Tr., dated Apr. 29,
    2010), because of, among other things, her “take on [certain] personalities,” id. at
    2478 (Trial Test. of Juror, dated Apr. 29, 2010). After an investigation, the court
    decided, over Mr. Gordon’s objection, that it would excuse her “out of an
    abundance of caution.” Id. at 2505.
    Ultimately, Mr. Gordon was convicted on all counts that were submitted to
    the jury. 9
    8
    (...continued)
    19, 2010. However, the presiding judge recused himself in late 2009, and Judge
    James Payne was assigned to the matter. Judge Payne reset the trial date to
    March 29, 2010. However, in light of numerous pending motions and an
    interlocutory appeal filed by Mr. Gordon, the trial ultimately did not begin until
    April 5, 2010.
    9
    Before the trial started, the government moved for, and the district
    court granted, dismissal of Count 16, a money laundering allegation.
    -15-
    F.    Post-Trial Proceedings
    The U.S. Probation Office prepared a Presentence Report (“PSR”),
    recommending various upward adjustments under the U.S. Sentencing Guidelines
    (“U.S.S.G.”) for offense-specific characteristics. 10 The parties filed multiple
    objections to the PSR. The PSR notably recommended a twenty-level
    enhancement under U.S.S.G. § 2B1.1(b)(1)(K), because Mr. Gordon’s fraudulent
    conduct, both individually and jointly with others in the conspiracy, caused an
    estimated loss to investors of, at the very least, an amount exceeding $7,000,000.
    However, the PSR made explicit that total loss could not be accurately calculated,
    and in that vein, set forth a potential alternative estimate of $10,720,000
    representing Mr. Gordon’s illicit gain from the stock scheme. Pertinently, the
    government objected both to the PSR’s calculation of loss, and to its alternative,
    gain figure, arguing that—taking the most conservative approach—reasonable
    estimations of loss (and alternatively, gain) far exceeded $20,000,000, which
    would merit a greater enhancement.
    Agreeing with the government, the district court determined that it would
    be too difficult to determine the losses suffered by each individual investor.
    Consequently, it calculated an illicit gain of $46,642,313 as an alternative
    10
    For its computations, the Probation Office used the 2009 edition of
    the U.S.S.G. Mr. Gordon has not taken exception to this choice. Therefore, we
    also reference that edition of the U.S.S.G.

    measure of loss, resulting in a twenty-two-level increase in Mr. Gordon’s offense
    level under § 2B1.1(b)(1)(L) of the Guidelines. The court subsequently arrived at
    a total offense level of forty-five and a criminal history category of I, which
    produced a guideline range of life. However, the court granted Mr. Gordon’s
    request for a substantial downward variance and sentenced him to a total of 188
    months’ imprisonment. 11 The court further ordered Mr. Gordon to pay
    $6,150,136.79 in restitution.
    The district court also ordered forfeiture of, inter alia, up to $1.702 million
    in equity in Mr. Gordon’s home and the full amount in his law firm bank accounts
    as directly forfeitable assets. The Delvest lots, along with some of Mr. Gordon’s
    other accounts and property, were later ordered forfeited as “substitute” assets.
    See generally 
    21 U.S.C. § 853
    (p) (providing for the forfeiture of substitute
    assets); United States v. Bornfield, 
    145 F.3d 1123
    , 1139 (10th Cir. 1998) (“An
    asset cannot logically be both forfeitable and a substitute asset. . . . Assets
    involved in or traceable to the offense are forfeitable once the requisite nexus is
    established. The substitute assets provision allows the forfeiture of other assets

    omission of the defendant.” (citation omitted)). Mr. Gordon now appeals his
    conviction and sentence, and the district court’s forfeiture orders. 12
    II. Discussion
    On appeal, Mr. Gordon raises multiple issues relating to the validity of his
    conviction and sentence, and the propriety of the government’s conduct (both
    before and after trial) related to the forfeiture of his assets. In the end, we find no
    reversible error and affirm Mr. Gordon’s conviction and sentence, as well as the
    district court’s forfeiture orders.
    A.    Claims Relating to the Sixth Amendment Right to Counsel
    Mr. Gordon first argues that the government improperly seized his assets
    and, as a consequence, substantially deprived him of his Sixth Amendment right
    to counsel. However, we hold that, even assuming arguendo that the government
    acted improperly, Mr. Gordon’s Sixth Amendment rights were not violated.
    The Sixth Amendment provides that “the accused shall enjoy the right . . .
    to have the Assistance of Counsel for his defence.” U.S. Const. amend. VI; see
    Caplin & Drysdale, Chartered v. United States, 
    491 U.S. 617
    , 624 (1989) (“[T]he
    Sixth Amendment guarantees a defendant the right to be represented by an
    otherwise qualified attorney whom that defendant can afford to hire . . . .”).
    12
    Because of the extensive nature of the facts in this case, we have
    offered supra only a general overview. We supplement the overview with
    additional relevant facts in resolving Mr. Gordon’s specific legal challenges.

    “This protean right has several manifestations, some familiar, some less familiar.”
    United States v. Rosen, 
    487 F. Supp. 2d 721
    , 726 (E.D. Va. 2007). Among these
    manifestations is the “qualified right to counsel of choice,” which “stems from a
    defendant’s right to decide what kind of defense he wishes to present.” United
    States v. Jones, 
    160 F.3d 641
    , 646 (10th Cir. 1998) (emphasis added) (quoting
    United States v. Collins, 
    920 F.2d 619
    , 625 (10th Cir. 1990)) (internal quotation
    marks omitted). This right may not be “improperly impede[d].” 
    Id.
     Indeed, the
    right to select counsel of one’s choice “has been regarded as the root meaning of
    the constitutional guarantee.” United States v. Gonzalez-Lopez, 
    548 U.S. 140
    ,
    147–48 (2006).
    Practical considerations, such as a defendant’s relative wealth or penury,
    can of course impose constraints on a defendant’s ability to exercise his right to
    counsel of choice—that is, to hire the attorney that he prefers. A defendant’s
    ability in this regard also may be limited by the claims of other parties to his
    resources. One such party may be the government. For instance, with regard to a
    defendant who is prosecuted by the government for certain crimes and convicted,
    “[t]he court . . . shall order that the person forfeit to the United States any
    property, real or personal, involved in such offense, or any property traceable to
    such property.” 
    18 U.S.C. § 982

    In 2007, before Mr. Gordon was indicted, the government filed caveats on
    the Delvest lots, and a lis pendens and a caveat on his residential property; it also
    seized two of his law firm bank accounts. In 2009, the government pursued
    forfeiture before the grand jury of the residence and the law office accounts. As
    returned by the grand jury, the indictment did not mention the Delvest lots.

    (a)(1)). Property “involved in” the offense “include[s] the money or other
    property being laundered (the corpus), any commissions or fees paid to the

    (internal quotation marks omitted). Further, “property ‘traceable to’ means
    property where the acquisition is attributable to the money laundering scheme
    rather than from money obtained from untainted sources.” 
    Id.
    In Caplin & Drysdale, the Supreme Court rejected any contention that “the
    Sixth Amendment puts limits on the forfeiture statute[s].” 
    491 U.S. at
    625–26.
    Assets that are properly forfeitable are not the defendant’s rightful property. See
    
    id. at 626
    . As ill-gotten gains, they are “another person’s money.” 
    Id.
     Indeed,
    these assets may belong to the government by virtue of the “relation-back”
    provision of 
    21 U.S.C. § 853
    (c), which by operation of law vests title to
    forfeitable property in the government “upon the commission of the act giving
    rise to forfeiture.” United States v. Jarvis, 
    499 F.3d 1196
    , 1203 (10th Cir. 2007)
    (quoting 
    21 U.S.C. § 853
    (c)) (internal quotation marks omitted); see United States
    v. Erpenbeck, 
    682 F.3d 472
    , 477 (6th Cir. 2012) (noting, as to the relation-back
    doctrine, “[i]f the cash were tainted property, title would have vested in the
    government at the time of [the defendant’s] fraud, which occurred prior to the
    bankruptcy filing, and the cash would not have entered the bankruptcy estate”).
    Based upon these principles, we have explained that “a criminal defendant has no
    Sixth Amendment right to use forfeitable assets to employ counsel.” Jones, 
    160 F.3d at 648
    .

    assets—in other words, it determined that they were not directly forfeitable. The
    grand jury did find, however, that Mr. Gordon’s residence was directly
    forfeitable, to the extent that it was connected to the IPG scheme. The
    government subsequently filed a Bill of Particulars that not only alleged that the
    residence was directly forfeitable, but also that the bank accounts were too,
    notwithstanding the grand jury’s findings.
    Mr. Gordon later filed a motion to dismiss on the grounds that the
    government’s forfeiture conduct violated his constitutional rights, and the district
    court scheduled a hearing on the issue of forfeiture. However, the case was
    reassigned to a different judge, who struck all of the scheduling dates, and after
    ordering a surreply from the government, denied Mr. Gordon’s motion to dismiss.
    The gravamen of Mr. Gordon’s claim is that the government wrongfully
    placed common law impediments on his property and thereby prevented him from
    accessing funds necessary to pay for his counsel of choice, in violation of the
    Sixth Amendment. As best as we can tell, his argument plays out as follows.
    First, some of the “restrained” property was not directly forfeitable; rather, it was
    “substitute” property that was off-limits to the government unless and until he is
    convicted, per our decision in Jarvis. 14 Second, even if his property was

    A defendant may own what the forfeiture statute calls “substitute
    property.” See 
    21 U.S.C. § 853
    (p). Such property “neither comprises the fruits
    of nor is connected to the defendant’s alleged crime.” Jarvis, 499 F.3d at

    forfeitable, the applicable provisions of the criminal forfeiture statute, 
    21 U.S.C. § 853
    , that authorize imposition of pre-indictment impediments on such property,
    require that interested persons receive prior notice and an opportunity to be heard,
    neither of which supposedly occurred here. These and other instances of
    unfairness, he contends, infringed upon his Sixth Amendment right to counsel. 15
    14
    (...continued)
    1203–04; see Bornfield, 
    145 F.3d at 1139
    . “[F]orfeiture of substitute property
    cannot occur until after the defendant’s conviction and a determination by the
    trial court that the defendant’s act or omission resulted in the court’s inability to
    reach [forfeitable property].” Jarvis, 
    499 F.3d at 1204
    ; see Erpenbeck, 682 F.3d
    at 477 (“But the government did not seek forfeiture of the cash as tainted
    property. It argued (and the district court found) that the cash was ‘substitute
    property’—untainted property that the government may seize to satisfy a
    forfeiture judgment if the tainted property is unavailable.” (emphasis added));
    United States v. Oregon, 
    671 F.3d 484
    , 487 (4th Cir. 2012) (“[W]hen the property
    representing direct proceeds of illegal activity is unavailable, the United States
    may instead seek the forfeiture of ‘substitute property’ of a defendant up to the
    value of the property that would otherwise be subject to forfeiture.”). More
    specifically, in order for the government to forfeit substitute property, it must
    establish that through “any act or omission of the defendant” one of five things
    has occurred—for example, forfeitable property cannot be located through the
    exercise of due diligence, or such property has been placed beyond the
    jurisdiction of the court. 
    21 U.S.C. § 853
    (p)(1). Furthermore, we reasoned in
    Jarvis that because the government has no pre-conviction interest in substitute
    property, it may not impose pre-trial restraints on a defendant’s substitute
    property. See 
    499 F.3d at 1204
     (“[Unlike forfeitable property,] the United States
    does not have a ripened interest in § 853(p) substitute property until (1) after the
    defendant’s conviction and (2) the court determines the defendant’s . . .
    forfeitable property is out of the government’s reach for a reason enumerated in
    § 853(p)(1)[].”).
    15
    We interpret Mr. Gordon’s briefs to make the alleged infringement of
    his Sixth Amendment rights the singular focus of his claims of prejudice; that is,
    the government’s alleged circumvention of the procedural requirements for
    imposing pre-trial restraints on property was the means to effectuate his
    (continued...)
    -22-
    The government’s conduct, he reasons, was deliberately calculated to deny him
    the right of access to his funds to use for the presentation of a defense. See, e.g.,
    Oral Arg. at 0:58–1:12 (“The convictions in this case should be reversed . . .
    because Appellee orchestrated a calculated scheme to deprive [Mr. Gordon] of the
    use of his own funds to prepare a viable defense.”).
    At bottom, then, Mr. Gordon contends that, through its intentional and
    15
    (...continued)
    unconstitutional injury. For example, he claims that the unlawful “seizure of his
    property . . . had profound implications under the Sixth Amendment for him to
    fund a viable defense.” Aplt. Reply Br. at 13.
    To the extent that there are arguments in Mr. Gordon’s trial briefing that he
    has failed to press on appeal, we will not accord him the benefit of those
    arguments, despite his apparent request for a complete incorporation of his trial
    briefings, see, e.g., Aplt. Opening Br. at 22 (“In this case, Appellee totally
    ignored the provisions of 18 U.S.C. [§] 853(e). . . . [I]t devised a scheme, every
    bit as complex as the criminal scheme alleged against [Mr. Gordon] in the
    indictment . . . . The actions taken by Appellee against [Mr. Gordon] are
    meticulously set out in trial counsel’s proffer (XI-1), which should be considered
    by this court, along with trial counsel’s motion to dismiss (X-1) and reply (X-
    351), in evaluating this appeal.”). Litigants who premise their appellate
    arguments on the incorporation by reference of arguments that they have
    advanced in their trial court papers, or other materials, do so at their peril. It is
    beyond peradventure that such a briefing technique is disfavored. See 10th Cir.
    R. 28.4 (“Incorporating by reference portions of lower court . . . briefs or
    pleadings is disapproved and does not satisfy the requirements of Fed. R. App. P.
    28(a) and (b).”). And we have repeatedly held that “[t]his court is under no
    obligation to consider arguments not fully set forth in a party’s appellate brief,
    including arguments incorporated by reference to prior pleadings or other
    materials.” Concrete Works of Colo., Inc. v. City & Cnty. of Denver, 
    321 F.3d 950
    , 979 n.14 (10th Cir. 2003); accord Lauck v. Campbell Cnty., 
    627 F.3d 805
    ,
    814–15 (10th Cir. 2010). We follow this path here, declining to consider any
    arguments that Mr. Gordon purports to assert through incorporation by reference
    to his trial court papers or other materials.
    -23-
    wrongful circumvention of the proper procedures for imposing pretrial restraints
    or impediments on his property, the government violated his Sixth Amendment
    right to counsel of choice. In making this argument, Mr. Gordon heavily relies on
    United States v. Stein, 
    435 F. Supp. 2d 330
     (S.D.N.Y. 2006). Specifically, he
    reasons, that like Stein, this case involves a situation where the government’s
    wrongful conduct resulted in a total deprivation of his right to counsel of choice.
    We disagree. Even assuming arguendo that the government acted improperly in
    imposing pretrial restraints on his property, Mr. Gordon cannot establish that this
    conduct violated his Sixth Amendment rights.
    In particular, Mr. Gordon’s attempt to establish a Stein-type violation is
    unavailing. In Stein, the court considered whether the government’s actions in
    “interfer[ing] with the . . . Defendants’ right to be represented as they choose,
    subject to the constraints imposed by the resources lawfully available to them,”
    violated their Sixth Amendment right to counsel and the right to a fair trial. 
    435 F. Supp. 2d at 369
    ; see 
    id. at 360
    . The court concluded that the government’s
    conduct in that case—which involved essentially convincing an employer to
    renege on prior legal-fee agreements with the defendants (its former
    employees)—violated the defendants’ rights because, among other reasons, the
    government had directly interfered with resources that the defendants had a
    fundamental expectation could be used to fund their defense. See 
    id. at 353
    (“Absent the [the government’s conduct], [the employer] would have paid the
    -24-
    legal fees and expenses of all of its partners and employees both prior to and after
    indictment, without regard to cost.”); 
    id.
     at 367–69.
    On appeal, the Second Circuit affirmed the district court, concluding first
    that the district court properly considered “pre-indictment state action that
    affected defendants post-indictment,” even though the Sixth Amendment right to
    counsel attaches “only upon indictment.” 16 United States v. Stein, 
    541 F.3d 130
    ,
    153 (2d Cir. 2008). More pertinently for this case, the Second Circuit agreed
    with the district court that the government’s conduct violated the defendants’
    right to counsel, insofar as it directly “intrude[d] on the attorney-client
    relationship.” Id at 154.
    However, even if Stein provided an appropriate guidepost in certain cases
    of governmental interference with the right to counsel of choice, Stein is patently
    distinguishable from the instant case. First of all, the Stein defendants had
    demonstrably “limited resources” and had made a showing that their trial strategy
    was diminished significantly by the government’s conduct. See 
    435 F. Supp. 2d 16
    The government here does not argue that Mr. Gordon’s Sixth
    Amendment right to counsel was not affected as a matter of law by its pre-
    indictment conduct. See generally Rothgery v. Gillespie Cnty., Tex., 
    554 U.S. 191
    , 198 (2008) (“The Sixth Amendment right of the ‘accused’ to assistance of
    counsel in ‘all criminal prosecutions’ is limited by its terms: ‘it does not attach
    until a prosecution is commenced.’” (footnote omitted) (quoting McNeil v.
    Wisconsin, 
    501 U.S. 171
    , 175 (1991))). Consequently, we assume without
    deciding that the government’s pre-indictment conduct could (as a matter of law)
    implicate Mr. Gordon’s Sixth Amendment rights.
    -25-
    at 371–72. Even though Mr. Gordon’s assets may have been incidentally
    constricted by the government’s conduct, he has not demonstrated that he was
    denied access to funds to pay for his defense in any substantial sense; certainly,
    he has not demonstrated a magnitude of financial deprivation anywhere close to
    that experienced by the Stein defendants.
    As the district court found in denying his motion to dismiss the indictment,
    [c]ontrary to Gordon’s claims of financial hardship, he has paid
    defense counsel over $900,000 in attorneys’ fees and costs since
    being indicted. Additionally, the government has submitted a
    loan application from November 2006, wherein Gordon stated his
    net worth was over $8.8 million ($8,816,000), including $2.8
    million in a CD and $398,000 in cash. Thus, irrespective of his
    allegations that the Government’s preservation of assets
    prevented him from hiring counsel of his choice, Gordon has not
    established he lacks funding to secure defense counsel.
    R., Vol. X, at 504–05 (Dist. Ct. Order, filed as sealed Feb. 8, 2010) (citation
    omitted).
    We agree with the district court that Mr. Gordon has not shown that he
    “ha[d] no assets, other than those restrained, with which to retain private
    counsel.” See Jones, 
    160 F.3d at 647
    . Mr. Gordon does not meaningfully dispute
    that he did have other resources to fund his defense, only noting in conclusory
    fashion that “he did not” have such resources, Aplt. Reply Br. at 14, and that “the
    Sixth Amendment guarantees him the right to use the assets he has lawfully
    -26-
    available,” 
    id.
     at 14 n.3. This will not suffice. 17
    Furthermore, unlike Stein, it is quite significant that Mr. Gordon’s counsel
    remained fully and actively engaged in the case throughout the entire trial court
    17
    More specifically, Mr. Gordon does not persuasively contest the
    district court’s factual conclusions, claiming only that they were “based on an
    asset statement filled out . . . almost three and a half years earlier,” and were
    contrary to the allegations in his counsel’s motion to withdraw that “he had not
    been paid for over twenty months and was owed $73,000 for expenses already
    incurred.” Aplt. Opening Br. at 27–28. Those assertions are unavailing,
    considering that our review of the district court’s factual findings is for clear
    error. See United States v. Ludwig, 
    641 F.3d 1243
    , 1247 (10th Cir. 2011) (“We
    also accept the district court’s specific factual findings unless clearly
    erroneous—no easy hurdle to clear, requiring the defendant to show that the
    findings are more than possibly or even probably wrong but pellucidly so.”);
    United States v. Tafoya, 
    557 F.3d 1121
    , 1126 (10th Cir. 2009) (analyzing the
    district court’s factual findings for clear error in considering a motion to dismiss
    the indictment, and reasoning that a “factual finding is clearly erroneous when ‘it
    is without factual support in the record or if, after reviewing all the evidence, we
    are left with a definite and firm conviction that a mistake has been made’”
    (quoting Plaza Speedway Inc. v. United States, 
    311 F.3d 1262
    , 1266 (10th Cir.
    2002))).
    Here, Mr. Gordon “was represented by his counsel of choice through the
    end of trial,” Aplee. Br. at 38, and the record clearly suggests that he had other
    available assets—including the equity in his home above the $1.7 million, which
    was the amount the government focused on in imposing the impediment on the
    Gordon residence—but did not elect to use those resources, see id.; R., Vol. X, at
    281 (Letter from Steven A. Tyrrell to Thomas O. Gorman & William McGrath,
    dated Oct. 29, 2009) (setting forth the government’s position that it was
    “amenable to any mortgage that would allow equity in [Mr. Gordon’s home] over
    and above the amount of traceable proceeds to be used for attorney fees”). Mr.
    Gordon claims that the government’s offer to make additional equity in his
    residence available for funding was essentially hollow in light of the fact that it
    asserted “open-ended claims” against his property, making it unlikely that a
    lender would provide a mortgage. See Aplt. Reply Br. at 4 n.1. But he provides
    no explanation for why this would necessarily be the case if the government’s
    interest—if any—in the property was only (at most) $1.7 million.
    -27-
    proceedings. 18 Indeed, our searching review of the record demonstrates that Mr.
    Gordon was represented in a thorough and vigorous fashion by the attorney he
    originally retained. Mr. Gordon’s allegations of prejudice come down to
    statements in which he suggests that “[p]reparing the defense to this action would
    require a team of experienced white collar and securities lawyers” who would
    have to sort through the thousands of documents prepared during the
    investigation—i.e., documents in his own war room. Id. at 16 (citation omitted)
    (internal quotation marks omitted). However, Mr. Gordon does not identify any
    concrete facts that would explain what was actually done in preparation for his
    defense and what additional steps his counsel would have taken, if Mr. Gordon
    had not been denied access to his funds through the government’s allegedly
    wrongful conduct.
    In light of the district court’s findings regarding Mr. Gordon’s access to
    considerable financial resources to pay his counsel, we will not engage in
    speculative ping-pong about the potential for harm to his defense resulting from
    the government-initiated restraints on his property—even assuming that those

    Indeed, the Second Circuit in Stein made it explicit that this situation
    of ongoing representation by counsel of choice was beyond the scope of the issues
    in that case. See 
    541 F.3d at
    158 n.15 (refusing to address the application of its
    own holding to a scenario where “[t]he defendant proceeds to trial with his or her
    chosen attorney, and the attorney is forced to limit the scope of his or her efforts
    due to the defendant’s financial constraints” and “[t]he defendant is convicted
    based on overwhelming evidence of his or her guilt”).

    restrains were improperly imposed. 19 See United States v. Dowie, 411 F. App’x
    19
    Our tacit proposition that Mr. Gordon must establish prejudice to
    prove a violation of his Sixth Amendment rights may warrant further explication.
    In Gonzalez-Lopez, the Supreme Court concluded, “[w]here the right to be
    assisted by counsel of one’s choice is wrongly denied, . . . it is unnecessary to
    conduct an ineffectiveness or prejudice inquiry to establish a Sixth Amendment
    violation.” 
    548 U.S. at 148
    . The right is “wrongly denied” where the “defendant
    is erroneously prevented from being represented by the lawyer he wants,
    regardless of the quality of the representation he received.”

     However,
    acknowledging that “most constitutional errors” do not affect the “structural”
    nature of the proceedings, see

    306 (1991)) (internal quotation marks omitted), a number of courts have applied a
    “prejudice” inquiry when addressing allegations of improper interference with a
    defendant’s Sixth Amendment right to counsel, see, e.g., Rosen, 
    487 F. Supp. 2d at 735
    ; United States v. Olis, Nos. H-07-3295 & H-03-217-01, 
    2008 WL 5046342
    ,
    at *12 (S.D. Tex. Nov. 21, 2008)—as opposed to allegations of a complete denial
    of that right. Notably, in such cases, unlike in Gonzalez-Lopez and Stein,
    “defense counsel . . . remain[s] fully engaged in th[e] case” and the allegation of
    interference really centers on its “adverse effect on [counsel’s] ability to mount a
    defense by reducing the resources available,” Rosen 
    487 F. Supp. 2d at 734
    .
    This approach has merit. Where the right to counsel of choice is not fully
    denied, but rather the situation is that counsel’s representation may have been
    constrained or limited by some external governmental factor (as is alleged here),
    the crux of the defendant’s claim is really that he has been denied the right to
    constitutionally effective representation. Cf. Gonzalez-Lopez, 
    548 U.S. at 148
    (warning against “confus[ing] the right to counsel of choice—which is the right to
    a particular lawyer regardless of comparative effectiveness—with the right to
    effective counsel—which imposes a baseline requirement of competence on
    whatever lawyer is chosen or appointed”). Ordinarily, a defendant cannot
    establish a Sixth Amendment violation based upon deficient performance “until
    the defendant is prejudiced.” 
    Id. at 147
    ; see United States v. Gaya, 
    647 F.3d 634
    ,
    638–39 (7th Cir. 2011) (“The defendant who has a lawyer, even an incompetent
    one, must to establish a violation of his constitutional right to effective assistance
    of counsel prove that he was prejudiced by the lawyer’s incompetence . . . .”);
    United States v. Lewis (Beau Lee Lewis), 
    611 F.3d 1172
    , 1177 (9th Cir. 2010)
    (“Defendant fails to identify any actual prejudice that occurred as a result of
    being represented by other counsel, who mounted a highly competent and
    (continued...)
    -29-
    21, 29 (9th Cir. 2010) (refusing to credit a Stein-type argument where the
    defendant failed to rebut the district court’s findings that he “maintained his
    counsel of choice throughout the trial, and there was no indication their defense
    work was limited in any way”); see also Rosen, 
    487 F. Supp. 2d at
    735–36
    (finding that defendants’ Stein-type argument was “not persuasive” where “the
    record . . . reflect[ed] that defense counsel . . . mounted a vigorous and effective
    defense notwithstanding the absence of [advances of attorney fees that were
    allegedly stanched by the government’s wrongful interference]”); Olis, 
    2008 WL 5046342
    , at *13 (“[The defendant] has failed to present any evidence showing
    either that he lacked funds needed to mount the defense of his choosing or that
    the defense presented at his trial was anything other than the defense he chose to
    present and would have presented [absent interference].”). In sum, we conclude
    that Mr. Gordon has not established a deprivation of his Sixth Amendment right
    to counsel of choice.
    B.    Sufficiency of the Evidence
    Mr. Gordon challenges the sufficiency of the evidence as to all of the
    substantive counts relating to the scheme to defraud with respect to the
    19
    (...continued)
    vigorous defense.”); cf. United States v. Morrison, 
    449 U.S. 361
    , 365 (1981)
    (“The premise of our prior cases is that the constitutional infringement identified
    has had or threatens some adverse effect upon the effectiveness of counsel’s
    representation or has produced some other prejudice to the defense. Absent such
    impact . . . there is no basis for imposing a remedy in that proceeding . . . .”).

    promotional campaigns for National Storm, Deep Rock, and Global Beverage. In
    addition, he challenges the counts that are predicated on the allegedly fraudulent
    nature of the opinion letters permitting restriction-free designations on some of
    the stocks at issue—specifically, the stock of National Storm, Deep Rock, and
    IPG. Finally, he claims that the evidence is insufficient to show that he
    obstructed, or attempted to obstruct, an official proceeding.
    “In reviewing the sufficiency of the evidence and denial of a motion for
    judgment of acquittal, this court reviews the record de novo to determine whether,
    viewing the evidence in the light most favorable to the government, any rational
    trier of fact could have found the defendant guilty of the crime beyond a
    reasonable doubt.” United States v. Irvin, 
    682 F.3d 1254
    , 1266 (10th Cir. 2012).
    In conducting this inquiry, the court may “not ‘weigh conflicting evidence.’” 
    Id.
    (quoting United States v. Evans, 
    318 F.3d 1011
    , 1018 (10th Cir. 2003)).
    Moreover, the “court considers the entire record, including both direct and
    circumstantial evidence, together with the reasonable inferences to be drawn from
    it.” United States v. Mendez, 
    514 F.3d 1035
    , 1041 (10th Cir. 2008).
    1.     The scheme to defraud
    Mr. Gordon makes various arguments that challenge the sufficiency of the
    government’s evidence regarding the counts associated with the charged scheme
    to defraud. First, without identifying the specific legal shortcomings of any
    -31-
    particular count, he makes a global argument that “the fax blasts, e-mails and the
    brochures were [not] illegal,” Aplt. Opening Br. at 33, for the National Storm,
    Deep Rock and Global Beverage promotions under § 17(b) of the Securities Act
    of 1933, 15 U.S.C. § 77q(b), “which makes it unlawful to publicize a stock for
    consideration from an issuer, underwriter, or dealer without disclosing the fact
    and amount of the payment,” United States v. Wenger, 
    427 F.3d 840
    , 843 (10th
    Cir. 2005). Citing our articulation of § 17(b)’s requirements in Wenger, see id. at
    852, Mr. Gordon contends that the faxes, e-mails, magalogs, etc., in this case
    required only a disclosure that the promoter received payment for the
    advertisement, and disclosure of the amount of the payment. He submits that all
    of the promotional material at issue contained such information and, contrary to
    the government’s arguments, it did not need to include the “name” of the
    promoters or whether the promoter was buying or selling the stock. See Aplt.
    Opening Br. at 31 (discussing evidence showing that “Pink Sheets wanted the
    SEC to include more requirements in such advertisements, such as identification
    of the promoters,” but as of the time of Mr. Gordon’s criminal conduct, no such
    requirements existed).
    However, as the government correctly notes, Mr. Gordon was not charged
    with violating § 17(b). Instead, as relevant here, he was charged under the
    general wire fraud statute, see 
    18 U.S.C. § 1343
    , and § 10b of the Securities Act
    of 1934, and the applicable rule promulgated thereunder, 
    17 C.F.R. § 240
    .10b-5
    -32-
    (“Rule 10b-5”), for “unlawful[ly] . . . employ[ing], in connection with the
    purchase or sale of any security . . . [a] manipulative or deceptive device or
    contrivance,” 15 U.S.C. § 78j(b). Mr. Gordon has failed to explain how technical
    compliance with § 17(b) would provide an effective safe harbor or immunity from
    prosecution for the manipulation of stock with the intent to defraud investors,
    which ordinarily would give rise to violations of the wire fraud statute and Rule
    10b-5. Cf. Wenger, 
    427 F.3d at
    852–54 (analyzing separate charges arising out of
    the same fraudulent scheme under § 17(b) and § 10(b), because “the government
    presented sufficient evidence to convince a reasonable jury beyond a reasonable
    doubt that [the defendant] had intent to defraud”). In other words, he offers no
    legal support for his global argument on appeal; consequently, we reject it.
    Even so, Mr. Gordon contends that with respect to the allegations related to
    Rule 10b-5, there can be “no liability . . . for failure to disclose information
    absent a duty to do so.” Aplt. Opening Br. at 32. Thus, as Mr. Gordon reasons,
    to the extent that the government’s allegations concern the non-disclosure of
    certain information in the promotional materials such as, for instance, the true
    identity of the source of the material—viz., the members of the underlying
    conspiracy—they are legally insufficient because there was no independent duty
    to disclose such information in this case, either by him or his co-conspirators. In
    essence, Mr. Gordon challenges whether the government showed, beyond a
    reasonable doubt, that there were actionable misstatements or omissions, as well
    -33-
    as a fraudulent intent to deceive investors. 20
    In support of this assertion, Mr. Gordon cites United States v. Schiff, 
    602 F.3d 152
     (3d Cir. 2010), a Third Circuit case that affirmed the dismissal of
    multiple Rule 10b-5 charges upon the theory that a corporate executive had an
    affirmative fiduciary duty to correct material misstatements made by another
    executive. In concluding that the government’s theory was too broad, the court in
    Schiff pointed out that § 10b gives rise to a duty to disclose in three separate and
    distinct circumstances: (1) where there is insider trading, (2) where a statute
    requires disclosure, or (3) where there has been an “inaccurate, incomplete or
    misleading prior disclosure.” 
    602 F.3d at 162
     (quoting Oran v. Stafford, 
    226 F.3d 275
    , 285–86 (3d Cir. 2000)) (internal quotation marks omitted).
    However, despite the holding in Schiff, “where a party without a duty elects
    20
    “Violations of section 10(b) and Rule 10b-5 can give rise to both
    civil liability and criminal liability.” United States v. Laurienti, 
    611 F.3d 530
    ,
    537 (9th Cir. 2010) (citing Chiarella v. United States, 
    445 U.S. 222
     (1980)). The
    basic elements for a Rule 10b-5 charge based upon misstatements or omissions in
    a civil context include the requirement that the government prove that the
    defendant “(1) made a misrepresentation or omission (2) of material fact, (3) with
    scienter, (4) in connection with the purchase or sale of securities, and (5) by
    virtue of the requisite jurisdictional means.” SEC v. Wolfson, 
    539 F.3d 1249
    ,
    1256 (10th Cir. 2008); accord SEC v. Curshen, 372 F. App’x 872, 877 (10th Cir.
    2010); cf. Wenger, 
    427 F.3d at 854
     (“Fraudulent intent is an element of a Section
    10(b) offense.”). The jury instructions on the 10b-5 allegations in this case were
    stated in a manner that was generally consistent with the foregoing requirements.
    See R., Vol. VIII, at 2544–45 (Jury Instructions, given Apr. 29, 2010). The
    primary distinction between 10b-5 actions in the civil and criminal context is that
    in the latter the “government must prove the offense beyond a reasonable doubt.”
    United States v. Gansman, 
    657 F.3d 85
    , 91 n.7 (2d Cir. 2011).
    -34-
    to disclose material facts, he must speak fully and truthfully, and provide
    complete and non-misleading information.” Curshen, 372 F. App’x at 880
    (emphasis added); see also Schiff, 
    602 F.3d at 162
     (“When you speak, however,
    and it is material, you are ‘bound to speak truthfully.’” (quoting Shapiro v. UJB
    Fin. Corp., 
    964 F.2d 272
    , 282 (3d Cir. 1992))); Thomas Lee Hazen, The Law of
    Securities Regulation § 12.9[10], at 471–72 (6th ed. 2009) (“[O]nce a statement
    of fact . . . has been made, the person making the statement is then under a duty to
    correct any misstatements . . . .”).
    In this case, the government offered substantial evidence that many aspects
    of the information disseminated in the promotional campaigns were false and
    misleading, and that misleading statements went uncorrected by numerous
    material omissions. See, e.g., R., Vol. VIII, at 3045–46 (noting that, despite an
    advertisement representing that “Wall Street expectations” were good for National
    Storm, the statement was incorrect and was made “to make it appear as though
    Wall Street was covering it and that the stock was going to rise because of it”);
    id. at 3049–50 (noting a fax blast’s assertion that “Putnam International
    Consulting,” was the source of payment for a particular fax blast, was false
    because the blast “was paid for out of . . . Gordon’s attorney trust account [by
    him and other members of the conspiracy]” and they “had control over more than
    10 percent of the company making [them] affiliates”); id. at 3085 (discussing
    language in one of the e-mail blasts encouraging investors to refer to the SEC’s
    -35-
    website for information seemingly related to National Storm, when certain
    conspirators knew that the company was, in fact, not registered with the SEC in
    light of its Pink Sheet status); id. at 3145–48 (describing a similarly misleading
    fax blast campaign with respect to Deep Rock, and noting that a statement
    representing that non-affiliated shareholders paid the fee for advertisements was
    false because, inter alia, Mr. Gordon “controlled the float”); id. at 214–15 (noting
    that, like in prior blasts, Mr. Sheptycki “made up” information on the identity of
    the source of a Global Beverage blast and projected growth numbers).
    Significantly, the evidence also tended to establish that there was a group
    of shareholders (of which Mr. Gordon was a part) who disguised their stake in the
    applicable stocks by using nominee accounts, and who fraudulently manipulated
    the price in order to make a profit, all at the expense of the general shareholders. 21
    21
    Mr. Gordon contends in passing that many of the “falsehoods” and
    instances of alleged misconduct simply were not actionable for various reasons.
    Most of his arguments are easily disposed of. For instance, he claims that, on
    cross-examination, Mr. Lindberg “admitted” the statements in the faxes and
    e-mails were correct, but Mr. Gordon does not explain which statements were
    “correct,” and his argument contradicts Mr. Lindberg’s long direct testimony. In
    addition, he argues that the information in some of the faxes was mere puffing.
    To be sure, generally, loose “statements of optimism are not actionable.” Hazen,
    supra, § 12.9[4], at 464; see id. at 464 nn.123, 128 & 130 (citing cases).
    However, “[m]isrepresentation by implying the existence of certain facts cannot
    be disguised as mere puffing.” Id. at 464. The statements identified by the
    government in the evidence are not “generalized [ones] of optimism that are not
    capable of objective verification.” Grossman v. Novell, Inc., 
    120 F.3d 1112
    , 1119
    (10th Cir. 1997). To the contrary, at the very least, those statements falsely imply
    that objective sources had predicted the stocks to skyrocket, and omit crucial

    -36-
    See, e.g., 
    id.
     at 3139–40 (noting that the “plan” as to Deep Rock “was to start the
    stock at four or five cents and gradually walk it up before the promotional effort
    started” and that the priming was “substantially . . . controlled”).
    On this record, we conclude that any rational trier of fact could have found
    that Mr. Gordon’s conduct was fraudulent within the meaning of the securities
    laws. See, e.g., United States v. Ware, 
    577 F.3d 442
    , 448 (2d Cir. 2009)
    (concluding that the evidence was sufficient to convict the defendant of securities
    fraud in a “pump-and-dump” scheme where he sent out press releases—regarding
    a company in which he owned millions of shares—that “fabricated . . . [the]
    sources of [the] factual information” in the press releases and failed to disclose
    the true sources of the funds allowing for release of the press releases); Wenger,
    21
    (...continued)
    information about “who” was really paying for the promotions. Inasmuch as a
    “reasonable investor would place [significance] on the withheld or misrepresented
    information,” Basic Inc. v. Levinson, 
    485 U.S. 224
    , 240 (1988), any rational trier
    of fact could have found Mr. Gordon guilty.
    He also makes a general contention that the use of nominee accounts was
    not illegal, and it was not improper to engage in “[t]imed sequences of buying and
    selling” in the stocks at issue. Aplt. Reply Br. at 19 (discussing evidence that
    suggested Pink Sheet stocks are often made up of a small group of investors).
    However, even assuming that the buying and selling of stock by a small group of
    individuals is not per se illegal, Mr. Gordon does not explain how it necessarily
    follows that the same is true where the transactional purpose is to create the false
    appearance of an active market for the shares in order to induce people to rely on
    that impression and buy the stock. And the testimony at trial tended to establish
    that these were the reasons for many of the conspirators’ nominee accounts,
    promotional campaigns, and the transaction sequences. See, e.g., R., Vol. VIII, at
    3140–42 (suggesting as much with respect to Deep Rock).
    -37-
    
    427 F.3d at 854
     (holding that there was sufficient evidence of fraud under § 10b,
    where the defendant sent out newsletters advising investors to buy a stock, which
    “at the same time” he was selling); cf. Stoneridge Inv. Partners, LLC v. Scientific-
    Atlanta, Inc., 
    552 U.S. 148
    , 158 (2008) (“[M]anipulative trading practices . . . are
    deceptive within the meaning of the rule.”); Santa Fe Indus., Inc. v. Green, 
    430 U.S. 462
    , 476 (1977) (noting that “manipulation,” as used in this context, “refers
    generally to practices, such as wash sales, matched orders, or rigged prices, that
    are intended to mislead investors by artificially affecting market activity”
    (emphasis added)); Ernst & Ernst v. Hochfelder, 
    425 U.S. 185
    , 199 (1976)
    (suggesting that manipulative conduct “connotes intentional or willful conduct
    designed to deceive or defraud investors by controlling or artificially affecting the
    price of securities”); Wilson v. Merrill Lynch & Co., 
    671 F.3d 120
    , 130 (2d Cir.
    2011) (“In order for market activity to be manipulative, that conduct must involve
    misrepresentation or nondisclosure.”). 22 Therefore, insofar as it is predicated
    22
    Mr. Gordon also makes something of a causation argument.
    Specifically, he contends that the observed price spikes in the stocks during the
    fraudulent “pumping” period were substantially attributable to the circumstances
    of the particular industries in which the companies operated (and, thus,
    presumably not attributable to the conspirators’ fraudulent conduct). For
    instance, the price of home-building company stocks was seemingly correlated
    with Hurricane Katrina. As a general matter, his briefing on this issue is skeletal
    at best. We would be justified in refusing to address it on that grounds alone.
    See Burrell v. Armijo, 
    603 F.3d 825
    , 835 (10th Cir. 2010) (“Without specific and
    reasoned argument . . . , we have no basis to reverse the district court’s
    decision.”). Nonetheless, as the government points out, “the jury was not
    (continued...)
    -38-
    upon the assertion that there was no evidence of actionable false and material
    statements or omissions made with respect to the promotional campaigns, with a
    fraudulent intent, Mr. Gordon’s sufficiency-of-the-evidence challenge is wholly
    without merit.
    Finally, the government charged Mr. Gordon with a violation of 
    18 U.S.C. § 1001
    , on the grounds that he falsely denied knowledge of the Deep Rock fax
    promotion to an SEC official (Count 22). See R., Vol. I, at 75. Mr. Gordon
    challenges his conviction under § 1001 on the grounds that “[i]f the fax blasts
    were legal, then whatever [he] told [SEC investigators] about them would not
    have been material.” Aplt. Opening Br. at 38. However, in light of the foregoing
    discussion, Mr. Gordon’s argument must fail because the promotional campaigns
    (including the fax blasts) were not legal.
    In any event, to establish “materiality” under § 1001, the government had
    to show that the statement had “a natural tendency to influence, or [be] capable of
    influencing, the decision of the decisionmaking body to which it was addressed.”
    United States v. Gaudin, 
    515 U.S. 506
    , 509 (1995) (alteration in original)
    22
    (...continued)
    required to accept [alternative theories for the prices’ rise and fall], particularly
    where the promotions hyped the stock based on the same external events that
    Gordon claims caused the price movements.” Aplee. Br. at 25; cf. United States
    v. Haymond, 
    672 F.3d 948
    , 956 (10th Cir. 2012) (noting that “[t]he jury was not
    required to credit [the defendant’s] assertions” on his own view of the evidence
    (emphasis added)).
    -39-
    (quoting Kungys v. United States, 
    485 U.S. 759
    , 770 (1988)) (internal quotation
    marks omitted). Here, a rational trier of fact could have concluded that Mr.
    Gordon’s statement denying any knowledge of the Deep Rock fax promotions
    satisfied this understanding of “materiality” because Deep Rock was one target in
    the SEC’s investigation, and a false statement by Deep Rock’s attorney that he
    had no knowledge of a promotional campaign—which, at that time, was
    potentially illegal—could have influenced the agency’s decision on how to craft
    its investigative focus. See 
    id.
     at 522–23 (noting that “the jury [must be allowed]
    to pass on the ‘materiality’ of [the defendant’s] false statements”).
    In other words, any rational trier of fact could have concluded that Mr.
    Gordon’s denial was capable of influencing the SEC’s investigation of the
    underlying scheme. See R., Vol. VIII, at 1777 (Investigator Draddy responding,
    “Absolutely” to the question, “Was the information about fax promotions for
    Deep Rock relevant [and important] to the SEC’s investigation?”); see also
    United States v. Oldbear, 
    568 F.3d 814
    , 825 (10th Cir. 2009) (holding that a false
    statement made to an FBI agent that the defendant had “no information” regarding
    the matter under investigation was “material” under § 1001(a)(2) because the
    statement related to one of the issues that was important to the underlying
    investigation). For that reason, Mr. Gordon’s challenge to Count 22 also must
    -40-
    fail. 23
    2.    Legality of the opinion letters
    Mr. Gordon also lodges a challenge to the sufficiency of the evidence with
    respect to the allegations that he prepared or endorsed “false” opinion letters for
    Deep Rock, National Storm, and IPG. 24 According to Mr. Gordon,
    Robert Bertsch never appeared to testify that the two opinion
    letters he wrote [for Ednet, the company IPG had merged with,
    and National Storm] were forgeries or that the companies he
    wrote about had not been formed at least two years earlier or that
    he had not determined that the shareholders listed in the opinion
    23
    Embedded in Mr. Gordon’s brief is the additional contention that he
    had an “ethical obligation” to protect the information about the Deep Rock
    promotional campaign because, at the time he was asked about it, he was
    representing Deep Rock. Aplt. Opening Br. at 38. However, Mr. Gordon points
    us to no privilege permitting an attorney to lie to a government official
    purportedly to protect his client’s interests, and we certainly are not aware of
    anything of the sort. Aside from the fact that Mr. Gordon appears to have been
    simultaneously or concurrently representing his clients in the face of seemingly
    patent conflicts of interest, see Okla. Rules of Prof’l Conduct R. 1.7 (noting that
    “a lawyer shall not represent a client if the representation involves a concurrent
    conflict of interest,” which includes cases where “there is a significant risk that
    the representation of one or more clients will be materially limited . . . by a
    personal interest of the lawyer”); see also Okla. Rules of Prof’l Conduct R. 1.7
    cmt. 10 (“[I]f the probity of a lawyer’s own conduct in a transaction is in serious
    question, it may be difficult or impossible for the lawyer to give a client detached
    advice.”), had he actually been concerned with his clients’ confidences, he could
    have declined to answer at all, see Okla. Rules of Prof’l Conduct R. 1.6(a) (“A
    lawyer shall not reveal information relating to the representation of a client unless
    the client gives informed consent . . . .”). Deceit is not an accredited tool of
    which a lawyer may avail himself in the representation of a client.

    Mr. Gordon asserts these challenges at two points in his brief—in
    “Proposition Two” and “Proposition Four.” However, we address his arguments
    here under the same heading for clarity.
    -41-
    letters had not obtained their stock as Rule 144 required.
    Similarly, the opinion letter written by [Mr. Gordon] involved a
    company, Deep Rock, whose stock, the testimony established,
    had been distributed to numerous parties, many in the Clark
    family [and could thus be transferrable through “tacking”], more
    than a decade before. There was no evidence [Mr. Gordon] knew
    that any shares of stock ultimately traded as a result of his
    opinion letter should not have done so or that the opinion letter
    failed to qualify for the Rule 144 exemption.
    Aplt. Opening Br. at 34. These assertions, however, are refuted by the record.
    There was ample evidence for a rational jury to determine that the information in
    the opinion letters was false, and that Mr. Gordon knew it. In fact, there was
    evidence that he laid the groundwork for many of the false representations. See,
    e.g., R., Vol. VIII, at 1493 (“[Mr. Gordon] told me that I should go talk to a
    couple of my friends, offer them money, a thousand dollars a piece or something
    in that range, and ask them to do me a favor to say they were shareholders of the
    company.”); id. at 1303–07 (Trial Test. of Donald Clark, dated Apr. 13, 2010)
    (referencing a transfer document issued by Mr. Gordon’s law office that purported
    to establish that Mr. Clark (as a shareholder-seller) had acquired Deep Rock
    shares “more than two years prior” despite the fact that Mr. Clark had never
    advised Mr. Gordon or anyone in his law office to this effect (internal quotation
    marks omitted)); id. at 1495 (stating that share transfer documents “were
    backdated to show that the shareholders owned the stock longer than they actually
    did, so upon becoming a public company those shares would be freely tradable to
    -42-
    sell in the market”); id. at 1279 (Trial Test. of Tom Klenda, dated Apr. 13, 2010)
    (noting that, despite the fact that he was listed as trustee for a trust that owned
    2,000,000 shares of Deep Rock stock, which Mr. Gordon indicated that he wanted
    to transfer in a Rule 144 opinion letter, he “was not involved in [the] transaction
    [that referenced him and] had no knowledge [of it]”). 25 Consequently, Mr.
    Gordon’s sufficiency-of-the-evidence argument with respect to the National
    Storm and Deep Rock opinion letters is meritless.
    Mr. Gordon, under Proposition Four, also argues that the government’s
    25
    Mr. Gordon also claims that, under Rule 144, “tacking of stock
    gifted to another extends the holding period to include the period held by the
    donor,” and in light of this, many of the shareholders listed actually qualified
    under the rule. Aplt. Reply Br. at 20. See generally M & A West, Inc., 
    538 F.3d at 1051
     (“Rule 144(k) further permits purchasers of restricted securities who
    acquire from non-affiliates in private transactions to comply with the two-year
    holding period by adding—‘tacking’—the holding period of the prior non-affiliate
    holder to their own holding period. Tacking is not permitted, however, if the
    purchaser acquires the securities directly from an affiliate in a private
    transaction.”); Black’s Law Dictionary 1590 (defining “tacking” as “[t]he joining
    of consecutive periods of possession by different persons to treat the periods as
    one continuous period”). However, even if the true facts of the shareholder
    ownership would have permitted the requirements of Rule 144 to be satisfied by
    tacking—and it is not clear to us that this is true, based upon Mr. Gordon’s
    cursory discussion of the factual underpinnings of the argument—the evidence
    established that Mr. Gordon elected to use fraudulent means to make the stocks
    freely tradeable. More specifically, the evidence demonstrated that Mr. Gordon
    knew the representations in the documents underlying the opinion letters were
    materially false, but nonetheless directed their creation. See R., Vol. VIII, at
    1305–07; see also id. at 1495 (noting that documents, which purported to set forth
    that paid “shareholders” owned 18th Letter stock, “were backdated to show that
    the shareholders owned the stock longer than they actually did” and “Mr. Gordon
    kn[e]w that [shareholders] would be signing backdated documents”).
    -43-
    evidence regarding the IPG transaction was insufficient, and thus, “there is no
    wire fraud [as to Count 23].” Aplt. Opening Br. at 40. Specifically, he claims
    that the witness testimony established that the opinion letter prepared for
    IPG—along with backdated corporate documents that Mark White signed—was
    accurate, and that backdating corporate documents to bolster the letter was not
    illegal in this context.
    “Conviction for wire fraud under 
    18 U.S.C. § 1343
     requires (1) a scheme or
    artifice to defraud or obtain property by means of false or fraudulent pretenses,
    representations, or promises, (2) an intent to defraud, and (3) use of interstate
    wire or radio communications to execute the scheme.” United States v. Ransom,
    
    642 F.3d 1285
    , 1289 (10th Cir. 2011) (footnote omitted) (quoting United States v.
    Gallant, 
    537 F.3d 1202
    , 1228 (10th Cir. 2008)) (internal quotation marks
    omitted); accord United States v. Cooper, 
    654 F.3d 1104
    , 1116 (10th Cir. 2011).
    Mr. Gordon does not suggest that a false opinion letter fabricated in order to
    facilitate the free trading of IPG shares would not constitute a scheme or artifice
    to defraud or obtain property by means of false or fraudulent pretenses,
    representations, or promises; rather, his argument attacks the factual
    predicate—viz., he contends that there was no evidence that the IPG opinion letter
    actually was false or that it failed to meet the requirements of Rule 144.
    Even assuming, as a general proposition, that backdating corporate
    -44-
    documents is not necessarily illegal, see generally United States v. Reyes, 
    577 F.3d 1069
    , 1073 (9th Cir. 2009) (“Backdating is not itself illegal . . . .”), the
    opinion letter that served as the basis for Count 23 in this case relied on more
    than mere backdated corporate records; it falsely represented that the shareholders
    had advised Mr. Bertsch’s office that the relevant shares of Ednet—the company
    with which IPG was merged—had been acquired in accordance with the
    requirements of Rule 144. For instance, the letter at the outset notes that the
    drafter “ha[d] been advised by [the shareholders] . . . that a sale will occur of
    1,000,000 shares of Common Stock.” Aplt. Addendum, ex. 19, at 1 (Letter from
    Robert Bertsch to Routh Stock Transfer, Inc., dated Sept. 17, 2004) (emphasis
    added). Further, on the second page, it notes that “we are advised that the Shares
    were deemed to be acquired by the Seller more than two years prior to the sale.”
    Id. at 2 (emphasis added). Neither of these assertions was true.
    Given the reference to the shareholders actually providing the “advice”
    regarding their holding status, it is not surprising that the transfer agent was
    misled into issuing the non-restrictive legends for IPG. See R., Vol. VIII, at
    1034–35 (Trial Test. of Jason Freeman, dated Apr. 12, 2010) (testifying that he
    relied on the representations made in the IPG opinion letter in order to “issue
    free-trading shares”). We are obliged when reviewing the sufficiency of the
    evidence to give the government the “reasonable inferences to be drawn from it.”
    Mendez, 
    514 F.3d at 1041
    . And here, the government offered evidence that Mr.
    -45-
    Gordon intended to mislead by creating this letter and directing Mr. Bertsch to
    sign it. See R., Vol. VIII, at 1604 (answering, “Yes. It came from his office,”
    when asked, “Did Mr. Gordon have an understanding this was a false document
    when he sent it to you?”); 
    id.
     (noting that Mr. Bertsch “sign[ed] a false opinion
    letter” in order to “complete the transaction”). Any rational trier of fact could
    have found the misrepresentations to be false and fraudulent. Cf. Cooper, 
    654 F.3d at
    1118–19 (concluding that the evidence was sufficient to sustain a wire
    fraud conviction where the government presented evidence at trial that the
    defendant transmitted false information by wire to induce individuals to continue
    to participate in a pyramid scheme). 26 In sum, Mr. Gordon’s challenge to his
    conviction of Count 23 is without merit.
    26
    Moreover, any rational trier of fact could have found the
    representations to be material. See Ransom, 
    642 F.3d at
    1289–90 (noting that
    “the materiality of a falsehood is a required element of wire fraud”). “In general,
    a false statement is material if it has a natural tendency to influence, or is capable
    of influencing, the decision of the decisionmaking body to which it was
    addressed.” Irvin, 682 F.3d at 1267 (quoting Neder v. United States, 
    527 U.S. 1
    ,
    16 (1999)) (internal quotation marks omitted); see United States v. Lawrence, 
    405 F.3d 888
    , 901 (10th Cir. 2005) (“To determine whether a statement is material the
    appropriate test is to examine whether it has a natural tendency to influence, or is
    capable of influencing a decision or action by another.”). Here, the false
    statements concerned whether the shareholders had advised Mr. Bertsch of the
    factual predicate for Rule 144 certification; it is beyond peradventure that these
    statements had a natural tendency to influence a transfer agent’s issuance of non-
    restricted certificates. Cf. Lawrence, 
    405 F.3d at 901
     (holding that the evidence
    was sufficient to sustain convictions of, inter alia, wire fraud, where the
    government showed the defendant’s fraudulent use of a seemingly valid physician
    provider number and Medicare codes, which had a “natural tendency to influence”
    and “induce payment” of false claims).
    -46-
    3.    Attempted Obstruction of an Official Proceeding
    Mr. Gordon also challenges Count 24, which charged him with a violation
    of 
    18 U.S.C. § 1512
    (c)(2)—that is, with corruptly obstructing, impeding, or
    influencing, or attempting to do so, an official proceeding. This charge was based
    upon the government’s contention that Mr. Gordon directed Mr. Singer to “sign a
    backdated agreement purporting to memorialize a sale of [IPG] stock that never
    took place,” Aplee. Br. at 27, and that Mr. Gordon actually created such a false
    document, with Mr. Singer’s help. The government argued that Mr. Gordon
    intended to present the document in the government-initiated civil forfeiture
    proceeding, in order to prevent forfeiture of his home.
    As we noted in Part I, supra, Mr. Singer gradually sold IPG shares on Mr.
    Gordon’s behalf, and at one point in November 2005, wire-transferred roughly
    $1.7 million of the proceeds to “pay off the mortgage on [Mr. Gordon’s] house.”
    R., Vol. VIII, at 1610. This allegedly fraudulent IPG-related conduct was the
    predicate for the government’s forfeiture action regarding Mr. Gordon’s house.
    According to Mr. Singer, around December 2007, Mr. Gordon directed him to
    endorse a false, backdated document that purported to memorialize a sale of IPG
    stock between Mr. Gordon and Mr. Singer. This sale supposedly took place in
    October 2005—prior to the November 2005 wire transfer—and the documents
    evinced a purchase price of approximately $1.9 million, an amount that somewhat
    -47-
    exceeded, but was similar to, the wire-transfer amount of $1.7 million. Mr.
    Singer testified that, at Mr. Gordon’s request, he returned to Mr. Gordon a signed
    copy of the purported agreement and a blank copy. Mr. Singer identified for the
    jury a record of a contemporaneous electronic communication from Mr. Gordon in
    which he informed Mr. Singer that he was “going to go w/unsigned version and
    let them no [sic] that the original [was] lost but this was the agreement.” R., Vol.
    VIII, at 1665 (internal quotation marks omitted). It is undisputed that the jury
    never heard evidence relative to whether Mr. Gordon ever presented either the
    signed or blank version of the purported purchase agreement to the government or
    in an official proceeding. 27 Mr. Singer confirmed, however, that “there was no
    27
    Apparently, as a matter of litigation strategy, the government elected
    not to present evidence to the jury regarding Mr. Gordon’s use of the purported
    agreement because (a) the government steadfastly maintained that it was
    sufficient proof of the offense that, with the aim of defeating the forfeiture of his
    home, Mr. Gordon corruptly directed Mr. Singer to sign a backdated, fabricated
    document and that, with Mr. Singer’s help, Mr. Gordon actually created such a
    false document, and (b) omitting such evidence of Mr. Gordon’s use of the
    document would permit the government to avoid conceivably turning Mr.
    Gordon’s counsel into witnesses. As to the latter point, outside of the jury’s
    hearing, Mr. Gordon’s counsel raised an objection with the district court
    regarding Mr. Singer’s testimony. They informed the court that Mr. Gordon had
    informed them that he had gone to Mr. Singer to obtain a copy of the purported
    purchase agreement; and when Mr. Singer could not unearth it, Mr. Gordon wrote
    down on a piece of paper the basic terms of the agreement; and, carrying this
    paper with them, counsel met with the government’s lawyers in January
    (apparently) 2008 to discuss the piece of paper and the purported purchase
    agreement, with the objective of convincing the government that there was
    nothing wrong with Mr. Singer’s 2005 transfer of funds to Mr. Gordon.

    was [his] selling [IPG] stock” and transferring sales proceeds to Mr. Gordon. Id.
    at 1666; see id. at 1610 (answering, with respect to the $1.7 million dollar wire
    transfer to Mr. Gordon, in response to the government’s question, “Were those
    also the proceeds of the sale from the [IPG] stock?,” “That’s correct”).
    “Under § 1512(c)(2), any person who ‘corruptly . . . obstructs, influences,
    or impedes any official proceeding or attempts to do so, shall be fined under this
    title or imprisoned not more than 20 years or both.’” United States v. Phillips,
    
    583 F.3d 1261
    , 1263 (10th Cir. 2009) (quoting 
    18 U.S.C. § 1512
    (c)(2)); accord
    United States v. Ahrensfield, 
    698 F.3d 1310
    , 1324 (10th Cir. 2012). Under this
    provision, “a defendant must act with the intent that his actions will influence a[n

    (...continued)
    Mr. Gordon’s counsel argued to the court that Mr. Singer’s testimony
    would implicate their efforts (on Mr. Gordon’s behalf) to use the purported
    purchase agreement to sway the government’s forfeiture decision and they were
    “going to wind up in the middle of this and this is going to conflict us both out of
    the case” and cause a mistrial. R., Vol. VIII, at 1651; see 
    id. at 1649
     (“[W]e’re
    going to wind up conflicted out of this case and cause a mistrial and that’s not
    what we’re trying to do here.”). The government contended that the argument of
    Mr. Gordon’s counsel was “a red herring” because Mr. Singer “is here to testify
    about what happened between him and Mr. Gordon,” 
    id. at 1654
    , and “the fact
    that they [i.e., Mr. Gordon’s counsel] were the vehicle for Mr. Gordon’s attempt
    to obstruct an investigation is immaterial,” 
    id. at 1652
    . According to the
    government, “[t]he critical fact here is . . . that the document [i.e., the purchase
    agreement] didn’t exist, it never existed, and that’s what this witness [that is, Mr.
    Singer] is going to testify about.” 
    Id. at 1652

    representations regarding the scope of Mr. Singer’s expected testimony in mind,

    -49-
    applicable] proceeding.” Phillips, 
    583 F.3d at 1263
    .
    Mr. Gordon essentially makes two arguments. First, he argues that “[t]he
    testimony never established that any ‘official proceeding’ was set or even
    contemplated during this time . . . [because the] in rem action against [the]
    residence . . . [was] stayed” in November 2007 and remained so at the time the
    alleged “obstruction” occurred, and the product of the alleged acts was intended
    to be presented to government lawyers, not the court. Aplt. Reply Br. at 23.
    Second, he suggests that the evidence simply did not show that he is guilty under
    § 1512(c)(2).
    “[O]fficial proceeding” in this context is defined as, inter alia, “a
    proceeding before a judge or court of the United States.” 
    18 U.S.C. § 1515
    (a)(1)(A). Mr. Gordon claims that the government’s evidence only showed
    that he wanted the fabricated share-purchase agreement for his records when he
    was meeting with the government regarding the forfeiture of his house and that,
    during the period in which he allegedly sought fabrication of the purchase
    agreement, the government-initiated civil forfeiture proceedings were technically
    stayed. These facts, he suggests, caused any proceeding to lose its character as
    “official.” These argument do not move beyond the threshold, however. In
    particular, we conclude that they are waived—specifically, his arguments aimed
    at showing that a stayed proceeding cannot constitute an “official proceeding” for
    -50-
    purposes of § 1512(c)(2), and that “[a]n ad hoc meeting between lawyers,” Aplt.
    Reply Br. at 23, similarly cannot constitute an official proceeding, such that the
    presentation of fraudulent documents in such a meeting could be deemed
    criminally actionable conduct.
    Mr. Gordon did not specifically present these arguments in his opening
    brief; rather, he attempts to formulate them for the first time in his reply brief. It
    is well settled that “[t]his court does not ordinarily review issues raised for the
    first time in a reply brief.” Stump v. Gates, 
    211 F.3d 527
    , 533 (10th Cir. 2000).
    Even then, the arguments are presented in a perfunctory and conclusory fashion,
    and we are rightly hesitant to definitively opine on such legally significant issues
    when they have received such cursory treatment. See, e.g., Cooper, 
    654 F.3d at 1128
     (“It is well-settled that ‘[a]rguments inadequately briefed in the opening
    brief are waived.’” (alteration in original) (quoting Adler v. Wal-Mart Stores,
    Inc., 
    144 F.3d 664
    , 679 (10th Cir. 1998))). Consequently, to the extent that Mr.
    Gordon purports to raise these arguments as a separate basis for error, we
    conclude that they are waived.
    Second, Mr. Gordon appears to contest whether the evidence actually
    showed that the creation of the false purchase agreement constituted an
    “obstruction,” where there was no evidence before the jury that the document was
    actually given to a government official or to the court. However, in addition to
    -51-
    its substantive provisions, § 1512(c)(2) also includes an attempt
    provision—authorizing conviction of an individual who “corruptly . . . attempts
    [to obstruct or impede]” an official proceeding, 
    18 U.S.C. § 1512
    (c)(2) (emphasis
    added)—and Mr. Gordon was charged in Count 24 both with the substantive
    offense and with the inchoate crime of attempt. Therefore, in assessing the
    sufficiency of the evidence regarding Count 24, we are free to focus on whether
    any rational finder of fact could have found Mr. Gordon guilty of the attempt
    offense (as opposed to the substantive offense), and we elect to do so.
    “An attempt [generally] requires both (1) an ‘intent to commit the
    substantive offense,’ and (2) the ‘commission of an act which constitutes a
    substantial step towards commission of the substantive offense.’” United States
    v. Washington (Deandre Washington), 
    653 F.3d 1251
    , 1264 (10th Cir. 2011)
    (quoting United States v. Vigil, 
    523 F.3d 1258
    , 1267 (10th Cir. 2008)); accord
    United States v. Irving, 
    665 F.3d 1184
    , 1195 (10th Cir. 2011).
    “A substantial step must be something more than mere preparation, yet may
    be less than the last act necessary before the actual commission of the substantive
    crime.” United States v. Fleming, 
    667 F.3d 1098
    , 1107 (10th Cir. 2011) (quoting
    Deandre Washington, 
    653 F.3d at 1264
    ) (internal quotation marks omitted). “The
    fact that further, major steps remain ‘before the crime can be completed does not
    preclude a finding that the steps already undertaken are substantial.’” Irving, 665

    843 F.2d 1280
    , 1297 (10th Cir.
    1988)). “[A] substantial step is appropriately found where the defendant
    undertook ‘an act adapted to, approximating, and which in the ordinary and likely
    course of things will result in, the commission of [a] particular crime.’” Fleming,
    
    667 F.3d at 1107
     (second alteration in original) (quoting Deandre Washington,
    
    653 F.3d at 1264
    ). “Importantly, the act or acts ‘must be strongly corroborative
    of the firmness of the defendant’s criminal intent.’” Irving, 
    665 F.3d at 1196
    (quoting United States v. Bunney, 
    705 F.2d 378
    , 381 (10th Cir. 1983)); see also
    United States v. Lucas, 
    499 F.3d 769
    , 781 (8th Cir. 2007) (en banc) (concluding
    that the defendant’s “earnest” request that two other individuals “claim ownership
    of [a] firearm . . . was enough to prove that [he] took a ‘substantial step’ toward
    obstruction of justice [under § 1512(c)(2)]”).
    Thus, the government was required to prove beyond a reasonable doubt (1)
    that Mr. Gordon intended to “corruptly” obstruct an official proceeding (here, the
    civil forfeiture proceeding), and (2) that he committed a substantial step toward
    the commission of the intended “obstruction.” Acting “corruptly” within the
    meaning of § 1512(c)(2) means acting “with an improper purpose and to engage
    in conduct knowingly and dishonestly with the specific intent to subvert, impede
    or obstruct the [forfeiture proceeding].” United States v. Friske, 
    640 F.3d 1288
    ,
    1291 (11th Cir. 2011) (alteration in original) (quoting United States v. Mintmire,
    
    507 F.3d 1273
    , 1289 (11th Cir. 2007)) (internal quotation marks omitted); cf.
    -53-
    United States v. Ogle, 
    613 F.2d 233
    , 238 (10th Cir. 1979) (in defining “corruptly”
    under 
    18 U.S.C. § 1503
    , noting that “corruption” means “[a]n act done with an
    intent to give some advantage inconsistent with official duty and the rights of
    others” (quoting Bouvier’s Law Dictionary, Vol. I) (internal quotation marks
    omitted)).
    Any rational trier of fact could have concluded that Mr. Gordon was guilty
    of attempting to violate § 1512(c)(2). First, as for his corrupt intent, the
    government’s evidence showed that Mr. Gordon directed Mr. Singer to sign a
    backdated agreement that memorialized a sale of IPG stock between the two. As
    the jury heard, “he wanted . . . to have it for his records when he was . . . meeting
    with the government regarding the forfeiture or seizure of his house.” R., Vol.
    VIII, at 1663. The evidence further showed that the share-purchase agreement
    specified that it was executed in October 2005—prior to Mr. Singer’s November
    2005 wire transfer of funds to Mr. Gordon—but Mr. Singer “never had an
    agreement regarding the shares of [IPG]” with Mr. Gordon. Id. at 1656. When
    Mr. Gordon asked for his endorsement on a backdated share-purchase agreement,
    Mr. Singer understood him “to be asking . . . to create false documents,” and Mr.
    Singer did so because “[Mr. Gordon] was a friend, [and Mr. Singer] was trying to
    help him out.” Id. at 1663.
    Any rational jury could have determined that the creation of these false
    -54-
    documents was for the corrupt purpose of redirecting the government, based upon
    false pretenses, away from property that it was trying to seize (i.e., Mr. Gordon’s
    home) in an official proceeding and that Mr. Gordon could foresee that the
    document would have this effect. See Friske, 
    640 F.3d at 1293
     (noting that, in
    making this showing, the government must establish that the “[defendant] knew
    that his actions were likely to affect a forfeiture proceeding”); United States v.
    Reich, 
    479 F.3d 179
    , 186 (2d Cir. 2007) (concluding that the defendant had
    “failed to show that the evidence was insufficient to establish a nexus between his
    actions and obstruction of [a] proceeding” where he completed “[a] forged Order
    [that] appeared to render moot [a litigation opponent’s] application to the Second
    Circuit for a writ of mandamus, [because] it was foreseeable that upon receiving
    the forged Order, [the opponent] would withdraw the application”).
    Furthermore, any rational jury could conclude that the evidence sufficiently
    established that Mr. Gordon took a “substantial step” toward the obstruction. Mr.
    Singer’s testimony suggested that Mr. Gordon intended to imminently use the
    false documents. See R., Vol. VIII, at 1665–66, 1668 (discussing text messages
    where Mr. Gordon implies that he was going to soon present a version of the
    unsigned (and false) document to the government after its receipt). As noted,
    even if “major steps remain,” a rational finder of fact may determine that the
    steps already completed are substantial. Irving, 
    665 F.3d at 1196
    ; see Deandre
    Washington, 
    653 F.3d at 1266
     (noting that a “substantial step” may be established
    -55-
    even though “several steps . . . remain before the planned [crime] . . . [actually]
    take[s] place”).
    More specifically, “[i]f the activity ha[s] proceeded to a further length, that
    is, if a tangible act which constituted proximate and tangible evidence of a real
    effort had emerged, the government’s [charge] [is] more tenable.” Deandre
    Washington, 
    653 F.3d at 1265
     (first and third alterations in original) (quoting
    United States v. Monholland, 
    607 F.2d 1311
    , 1317 (10th Cir. 1979)) (internal
    quotation marks omitted). And we look to see whether the act or acts strongly
    corroborate the firmness of the defendant’s intent to carry out the substantive
    offense. See Irving, 
    665 F.3d at 1198
    . Here, any rational finder of fact could
    have found that Mr. Gordon’s direction to Mr. Singer to endorse a backdated
    share-purchase agreement and Mr. Gordon’s actual creation of such an agreement
    (with Mr. Singer’s help) amounted to a tangible act. And that this act strongly
    corroborated the firmness of Mr. Gordon’s corrupt intent to obstruct an official
    proceeding. In particular, there was no evidence before the jury that Mr. Gordon
    expressed second thoughts about his corrupt plan, or in any other respect changed
    his mind about the criminal endeavor.
    Unlike in Monholland, this is not a situation where a defendant just
    engaged in “mere abstract talk.” 
    607 F.2d at 1318
    ; cf. Irving, 
    665 F.3d at
    1200–01 (concluding, that defendant’s conduct, “viewed in the aggregate”
    -56-
    amounted to more than abstract talk, where he “active[ly] solicit[ed]” an
    undercover agent to secure a killer for a murder-for-hire contract, achieved the
    “actual consummation of a murder-for-hire contract,” and took “concrete actions
    to facilitate the completion of the contract”). In responding to Mr. Gordon’s
    motion for judgment of acquittal, the government forcefully hammered this point
    home:
    [T]he fact that Mr. Gordon never lied to [the] court[] doesn’t
    matter. The count alleges that he endeavored to obstruct justice.
    He endeavored, not by thinking about it, not by walking around
    and talking to himself about it . . . but by doing something, by
    talking to Rick Singer about it, by sending him documents, and
    by instructing . . . Rick Singer to backdate the document and
    create a false document [and that] is sufficient.
    R., Vol. VIII, at 2378–79. Thus, taking account of all of the circumstances, we
    conclude that the government presented sufficient evidence for a rational
    factfinder to conclude that Mr. Gordon possessed the requisite corrupt intent to
    obstruct or impede an official proceeding and took a substantial step to
    accomplish that end. Accordingly, we reject Mr. Gordon’s sufficiency-of-the-
    evidence challenge to his conviction of Count 24. 28
    28
    Mr. Gordon also argues that there is no indication that he
    “intentionally harassed” Mr. Singer. See Aplt. Reply Br. at 24 (discussing
    § 1512). But he points to no portion of § 1512(c)(2) that contains an intentional
    harassment component, nor any case that recognizes such a patina on the
    provision. Furthermore, like his argument on the scope of § 1512(c)(2), Mr.
    Gordon’s argument on this issue is fragmentary and cursory. Thus, we decline to

    C.    Fifth Amendment
    Mr. Gordon complains that the district court erred in permitting the
    government to insinuate guilt by introducing evidence that infringed upon his
    Fifth Amendment right to remain silent. At trial, the government offered the
    testimony of Mr. Lindberg (over objection), which established that he and Mr.
    Gordon had discussed who should be permitted to testify in the proceedings
    before the SEC. Moreover, two witnesses—who were incidentally involved in the
    scheme—testified that Mr. Gordon advised them to take the Fifth Amendment.
    The testimony was offered to corroborate Mr. Lindberg’s testimony that he and
    Mr. Gordon had essentially calculated a cover-up strategy. Mr. Gordon claims
    that this tactic tainted the invocation of his own Fifth Amendment right not to
    testify at trial, which he in fact exercised.
    “We review a district court’s evidentiary rulings for an abuse of discretion,
    considering the record as a whole.” United States v. Ledford, 
    443 F.3d 702
    , 707

    rights.” Jones,

    privilege against self-incrimination is a question of law, which we review de

    application of the Fifth Amendment privilege against self-incrimination”).
    “The Fifth Amendment provides, in relevant part, that no person ‘shall be
    compelled in any criminal case to be a witness against himself.’” United States v.
    Mike, 
    632 F.3d 686
    , 697 (10th Cir. 2011) (quoting U.S. Const. amend. V)). It

    otherwise provide the State with evidence of a testimonial or communicative
    nature.” Schmerber v. California, 
    384 U.S. 757
    , 761 (1966). It further prevents
    “adverse comment[s] . . . on a defendant’s failure to take the stand in a criminal
    trial.” Griffin v. California, 
    380 U.S. 609
    , 615 (1965) (Harlan, J., concurring);
    see United States v. Templeman, 
    481 F.3d 1263
    , 1265 (10th Cir. 2007) (“[A]
    defendant’s Fifth Amendment privilege against self-incrimination prohibits a
    prosecutor from commenting on a defendant’s exercise of his right not to
    testify.”); United States v. Nelson, 
    450 F.3d 1201
    , 1212 (10th Cir. 2006).
    Mr. Gordon contends that the government’s evidence tainted his own
    invocation of the Fifth Amendment privilege during trial. 29 He reasons that the
    29
    Mr. Gordon appears to make a related argument that “[a] lawyer’s
    effort to advise his client of the full range of legal options available, including
    taking the Fifth Amendment, . . . cannot be portrayed as . . . wrongdoing” as a
    general matter. Aplt. Opening Br. at 44. In support he cites United States v.
    Farrell, 
    126 F.3d 484
     (3d Cir. 1997), a Third Circuit case that dealt primarily
    with the meaning of “corrupt persuasion” under the witness-tampering statute, see
    
    18 U.S.C. § 1512
    (b)(3). Mr. Gordon’s related argument lacks merit. In
    (continued...)
    -59-
    evidence introduced by the government (noted above) insinuated that “taking the
    Fifth” is what guilty people do. But the evidence here did no such thing. As
    discussed, it is absolutely true that “a defendant’s Fifth Amendment privilege
    against self-incrimination prohibits a prosecutor from commenting on a
    defendant’s exercise of his right not to testify.” Templeman, 
    481 F.3d at 1265
    .
    However, “[w]hen evaluating comments [or evidence] bearing upon a defendant’s
    failure to testify, we look to see if the language used was ‘manifestly intended to
    be a comment on the defendant’s failure to testify’ or was of ‘such character that
    the jury would naturally and necessarily take it to be such a comment.’” 
    Id.
    (emphasis added) (quoting United States v. Rahseparian, 
    231 F.3d 1267
    , 1273
    (10th Cir. 2000)); see United States v. Ivory, 
    532 F.3d 1095
    , 1100 (10th Cir.
    2008) (“[T]o determine whether . . . [a] remark will be considered a comment on
    the defendant’s failure to testify[,] . . . [we must assess] whether the language

    (...continued)
    particular, his reliance on Farrell is misguided. At issue there was whether the
    defendant’s conduct itself was sufficient to support a criminal charge under the
    witness-tampering statute. See Farrell, 
    126 F.3d at
    485–86. Specifically, Farrell
    dealt with whether evidence of a defendant persuading his alleged co-conspirator
    to not reveal information to authorities could constitute “corrupt persuasion”
    under 
    18 U.S.C. § 1512
    (b). 
    Id.
     at 488–89. The court found that “more culpability
    is required for a statutory violation [of § 1512(b)] than that involved in the act of
    attempting to discourage disclosure in order to hinder an investigation.” Id. at
    489. However, Farrell tells us nothing about whether evidence relating to third
    parties’ invocation of the Fifth Amendment privilege may detrimentally taint a
    defendant’s invocation of the privilege; in other words, Farrell says nothing
    about the issue before us.
    -60-
    used was manifestly intended or was of such character that the jury would
    naturally and necessarily take it to be a comment on the failure of the accused to
    testify.” (quoting United States v. Barton, 
    731 F.2d 669
    , 674 (10th Cir. 1984))
    (internal quotation marks omitted)).
    Mr. Gordon has pointed to no statement in the record that comes close to
    meeting this standard. Instead, he simply asserts conclusorily that the
    government’s conduct indirectly satisfies it. See Aplt. Opening Br. at 44 (“By its
    action, [the government] indirectly accomplished what has routinely been held
    justification for a mistrial—commenting on a defendant’s right to remain silent.”).
    That is not enough. Cf. In re Martinez, 126 F. App’x 890, 899 (10th Cir. 2005)
    (“[Appellants] simply continue to assert a general Fifth Amendment claim that
    answering the certified questions would impinge on their rights against self-
    incrimination. This is insufficient to invoke the Fifth Amendment.”).
    To the contrary, the evidence related to Mr. Gordon’s discussions with
    others about their testimony in an SEC proceeding; it did not pertain to Mr.
    Gordon’s invocation of his own Fifth Amendment right in his criminal trial. The
    Fifth Amendment prevents a prosecutor from “comment[ing] on the failure of the
    defendant to provide . . . evidence,” or to speak. Rahseparian, 
    231 F.3d at 1274
    (emphasis added); see United States v. Hamilton, 
    587 F.3d 1199
    , 1217 (10th Cir.
    2009). It does not prevent the evidence elicited in this case because that evidence
    -61-
    did not reasonably (or necessarily) refer to Mr. Gordon’s invocation of his own
    Fifth Amendment right not to testify. See Nelson, 
    450 F.3d at 1212
     (“The general
    rule of law is that once a defendant invokes his right to remain silent, it is
    impermissible for the prosecution to refer to any Fifth Amendment rights which
    defendant exercised.” (quoting United States v. Burson, 
    952 F.2d 1196
    , 1201
    (10th Cir. 1991)) (internal quotation marks omitted)); see also United States v.
    Hanrahan, 
    508 F.3d 962
    , 968 (10th Cir. 2007) (rejecting an argument that the
    prosecution’s use of the defendant’s prior testimony was in some way an effort to
    comment on his decision not to testify at the trial at which it was introduced,
    because the “prosecutor revealed nothing that . . . would cause the jury to
    consider it a comment on [the defendant’s] choice not to testify”). It is for this
    reason that we reject Mr. Gordon’s Fifth Amendment challenge. As the district
    court aptly noted, Mr. Gordon “should not be permitted to perpetuate . . . a
    stock-manipulation scheme and claim that evidence of the cover-up is somehow
    protected simply because he is an attorney.” R., Vol. VIII, at 371 (Trial Tr.,
    dated Apr. 8, 2010).
    D.    Juror Dismissal
    Mr. Gordon argues that the district court erred in excusing a petit juror
    without adequate cause. At trial, after the government rested its case, a member
    of the court’s staff was informed by a juror that she wanted to serve as an
    -62-
    alternate because her continued presence on the jury “could affect the outcome of
    the case.” R., Vol. VIII, at 2468. The juror further commented that, “perhaps” in
    light of her “take on personalities . . . and [her] take on some of the bits of th[e]
    case . . . [she] may be a roadblock.” Id. at 2478. After carefully conducting a
    one-on-one inquiry with each member of the panel—during which time the court
    asked whether this particular juror had made comments that could have
    contaminated the jury 30—it decided, over Mr. Gordon’s objection, that it would
    excuse her “out of an abundance of caution.” Id. at 2505.
    “We have stated that the determination of ‘whether to excuse a juror rests
    on whether the juror can remain impartial.’” United States v. Brothers, 
    438 F.3d 1068
    , 1071 (10th Cir. 2006) (quoting United States v. Black, 
    369 F.3d 1171
    , 1176
    (10th Cir. 2004)), abrogated in part on other grounds as recognized in United
    States v. Soza, 
    643 F.3d 1289
    , 1291 (10th Cir. 2011); see also United States v.
    Wood, 
    299 U.S. 123
    , 145–46 (1936) (“Impartiality is not a technical conception.
    It is a state of mind. For the ascertainment of this mental attitude of appropriate
    indifference, the Constitution lays down no particular tests and procedure is not
    chained to any ancient and artificial formula.”). “This rule is based on a
    defendant’s Sixth Amendment right to a fair trial ‘by an impartial jury.’”
    Brothers, 
    438 F.3d at 1071
     (quoting U.S. Const. amend. VI).
    30
    It was determined, ultimately, that “she didn’t contaminate the rest of
    the pool.” R., Vol. VIII, at 2504.
    -63-
    The district court has broad discretion in determining whether to excuse a
    juror for potential bias. See Bornfield, 
    145 F.3d at 1132
     (“It is well settled that
    the district court has broad discretion in determining how to handle allegations of
    juror bias.”); United States v. McIntyre, 
    997 F.2d 687
    , 697 (10th Cir. 1993)
    (“Whether an individual is qualified to serve as a fair and impartial juror is a
    decision that is firmly within the discretion of the district court.”); see also Black,
    
    369 F.3d at 1176
    . And the decision to dismiss—or not to dismiss—a juror is
    reviewed only for an abuse of discretion. See Black, 
    369 F.3d at
    1176–77; see
    also Skilling v. United States, 
    130 S. Ct. 2896
    , 2918 (2010) (“Reviewing courts
    are properly resistant to second-guessing the trial judge’s estimation of a juror’s
    impartiality, for that judge’s appraisal is ordinarily influenced by a host of factors
    impossible to capture fully in the record—among them, the prospective juror’s
    inflection, sincerity, demeanor, candor, body language, and apprehension of
    duty.”); United States v. Bolden, 
    596 F.3d 976
    , 980–81 (8th Cir. 2010) (affirming
    the district court’s dismissal of a juror that was made largely out of an abundance
    of caution in light of the juror’s brief conversation with the defendant’s
    girlfriend); Bornfield, 
    145 F.3d at
    1132–33 (affirming the district court’s
    dismissal of a juror as an alternate where the juror expressed displeasure with the
    pace of the trial).
    “Under the abuse of discretion standard, a trial court’s decision will not be
    disturbed unless the appellate court has a definite and firm conviction that the
    -64-

    permissible choice in the circumstances.” United States v. Chanthadara, 
    230 F.3d 1237

    Warner, 
    498 F.3d 666
    , 689 (7th Cir. 2007) (“[A] district court abuses its
    discretion in the context of juror removal only ‘if the juror was discharged
    without factual support or for a legally irrelevant reason.’” (quoting United States
    v. Edwards, 
    303 F.3d 606
    , 631 (5th Cir. 2002))). Compare Brothers, 
    438 F.3d at
    1071–72 (applying an abuse-of-discretion standard to the district court’s decision
    to remove a juror for cause), with Black, 
    369 F.3d at
    1176–77 (applying an abuse-
    of-discretion standard to the district court’s decision not to remove a juror for
    medical reasons).
    Mr. Gordon contends that the district court essentially lacked good cause
    for excusing the juror. However, we need not address whether the district court
    erred in discharging the juror. Even if it did so, we will not reverse “unless it
    resulted in prejudice to the defendant.” Brothers, 
    438 F.3d at 1072
    ; see 2 Charles
    Alan Wright & Peter J. Henning, Federal Practice and Procedure § 388, at 659
    (4th ed. 2009) (“Defendant is entitled to a new trial because of the substitution of
    an alternate juror prior to the start of deliberations only if he can demonstrate that
    he was prejudiced by the substitution.” (emphasis added)); id. at 659 n.22
    (collecting cases); see also id. at 659–60 (noting that, in showing prejudice, “it is
    -65-
    not enough that the juror who was excused was thought by the defendant to be
    biased in his favor”). And we conclude that there was no such prejudice to Mr.
    Gordon.
    Here, the juror in question “gave no indication [as to] which side she
    favored,” Aplee. Br. at 59, and Mr. Gordon “fails to point to any concrete factor
    that moves [his] assertion [of prejudice] beyond the realm of mere speculation,”
    Brothers, 
    438 F.3d at 1073
    . More specifically, although Mr. Gordon suggests that
    he was denied the participation of a “highly conscientious juror,” he fails to
    demonstrate that the remaining jurors were not just as conscientious or fair. See
    Brothers, 
    438 F.3d at 1072
     (“[T]here is no indication that the court’s replacement
    of the juror in question with an alternate juror resulted in a biased jury or an
    otherwise unfair trial.”); see also United States v. Thompson, 
    528 F.3d 110
    , 121
    (2d Cir. 2008) (“[The defendant] points to no evidence that the substitution [of a
    juror] created bias or prejudiced his defense.”); United States v. Vega, 
    72 F.3d 507
    , 512 (7th Cir. 1995) (“[W]e will not overturn a conviction for a Rule 24(c)
    violation unless appellant can show prejudice.”). And Mr. Gordon offers no
    allegation, much less any evidence, that the resulting juror pool was tainted or
    otherwise adversely affected. See United States v. Bradley, 
    644 F.3d 1213
    , 1282
    (11th Cir. 2011) (“Conjecture about the impact the replacement of a juror had on
    the jury’s verdicts is . . . insufficient evidence of prejudice.”). For these reasons,
    we reject his claim related to the district court’s dismissal of the juror.

    E.    Speedy Trial Act
    Mr. Gordon contends that certain provisions of the Speedy Trial Act, 
    18 U.S.C. §§ 3161
    –3174, were violated when the district court continued the date for
    commencement of the trial—after the unsealing of the indictment on February 10,
    2009—to January 19, 2010, and then subsequently to April 5, 2010. He claims
    that the district court “failed to articulate the information necessary to justify . . .
    [the] continuances.” Aplt. Opening Br. at 49.
    As alluded to in Part I, supra, on February 26, 2009, the government filed
    an unopposed motion to declare the case complex pursuant to the provisions of 
    18 U.S.C. § 3161
    (h), in light of the massive pending discovery and complex legal
    issues presented. The district court granted the motion, declared the case
    “complex,” and concluded that the “ends of justice” outweighed the public’s
    interest in a speedy trial. A few days later, the district court set the trial date for
    January 19, 2010, and reiterated that, under 
    18 U.S.C. § 3161
    (h)(8)(A), the “ends
    of justice would be served by granting [the] continuance.” 31 R., Vol. I, at 141
    31
    The district court referred to provisions concerning ends-of-justice
    continuances that were applicable before 2008. See R., Vol. I, at 118 (Order
    Granting Unopposed Mot. of United States to Declare This Case a Complex
    Matter, filed Mar. 10, 2009) (citing 
    18 U.S.C. §§ 3161
    (h)(8)(A) and
    3161(h)(8)(B)(ii) (2006)). However, in 2008, “Congress redesignated 
    18 U.S.C. § 3161
    (h)(8) as 
    18 U.S.C. § 3161
    (h)(7).” United States v. Hernandez-Mejia, 406
    F. App’x 330, 331 n.2 (10th Cir. 2011); see Judicial Administration and Technical
    Amendments Act of 2008, Pub. L. No. 110-406, § 13,

    (Notice of Electronic Filing, dated Mar. 17, 2009).
    After the case was reassigned to another district court judge (i.e., Judge
    Payne), he struck the pretrial conference and January 19th trial date. On March
    17, 2010, Mr. Gordon filed a motion to dismiss under the Speedy Trial Act,
    arguing that the continuances in the case were inadequately explained and were
    not supported by a basis for exclusion under the Act. The court denied this
    motion, and the trial began on April 5, 2010.

    commence within 70 days after he is charged or makes an initial appearance,

    The parties agree that the seventy-day clock under the Act
    commenced on the day the indictment was unsealed. See 
    18 U.S.C. § 3161
    (c)(1)
    (noting “the trial of a defendant charged in an information or indictment . . . shall
    commence within seventy days from the filing date (and making public) of the
    information or indictment”). That is, there is no argument that Mr. Gordon’s
    charges were made “public” before February 10, 2009, or that the speedy-trial
    clock should have begun at an earlier date for any other reason. We are content
    to proceed based upon the parties’ agreement on this matter.
    -68-
    the court determines—“either orally or in writing”—should be excluded because
    “the ends of justice served by the granting of such continuance outweigh the best
    interests of the public and the defendant in a speedy trial,” 
    id.
     § 3161(h)(7)(A).
    As relevant here, the factors to be considered in granting a continuance under
    § 3161(h)(7)(A) include “[w]hether the case is so unusual or so complex . . . that
    it is unreasonable to expect adequate preparation for pretrial proceedings or for
    the trial itself within the time limits established by [the Act].” Id.
    § 3161(h)(7)(B)(ii).
    We review the district court’s decision to grant a continuance for the “ends
    of justice” for an abuse of discretion. See United States v. Toombs, 
    574 F.3d 1262
    , 1268 (10th Cir. 2009) (“We apply an abuse of discretion standard to a
    district court’s decision to grant an ends-of-justice continuance . . . .” (quoting
    United States v. Gonzales, 
    137 F.3d 1431
    , 1433 (10th Cir. 1998)) (internal
    quotation marks omitted)). “This court [otherwise] reviews de novo . . . the
    district court’s compliance with the legal requirements of the Speedy Trial Act.”
    
    Id.
    In this case, the district court’s original order granting the government’s
    request for a continuance noted the voluminous discovery in the case, including
    documents detailing the hundreds of financial transactions that formed the basis
    for the charges. Further, the government’s motion set forth in detail the hundreds
    -69-
    of thousands of documents that needed to be catalogued and separated, so that the
    parties could “identify[]” the relevant ones. R., Vol. I, at 105 (Unopposed Mot.
    of United States to Declare this Case a Complex Matter, filed Feb. 26, 2009). We
    conclude that the district court’s findings were sufficient to justify the ends-of-
    justice continuance up to January 19, 2010, because it is obvious “what factors
    [it] relied upon in making its determination.” Larson, 
    627 F.3d at 1206
    ; cf. 
    id.
    (concluding that the ends-of-justice continuance was inadequate where the district
    court did not make clear the factors it relied upon in making its determination).
    Indeed, the record is clear that the district court’s decision was based on the
    fact that the transactional evidence was extensive and complex, and that it would
    take additional time to sufficiently analyze and organize the evidence before trial.
    These facts were identified both in the court’s order, see, e.g., R., Vol. I, at 118
    (“In this case, the number of defendants, the voluminous discovery [previously
    referenced in the order] and the ongoing nature of the investigation render the
    matter so complex as to warrant the grant of an ends-of-justice continuance
    . . . .”), and by reference to the government’s motion, see, e.g., 
    id.
     at 104–05; cf.
    Toombs, 
    574 F.3d at 1271
     (“[T]he district court need not articulate facts that are
    obvious and set forth in the motion to continue in granting an ends-of-justice
    continuance.”).
    While we have previously held that “[s]imply identifying an event, and
    -70-
    adding the conclusory statement that the event requires more time for counsel to
    prepare, is not enough,” Toombs, 
    574 F.3d at
    1271–72, the district court’s
    findings here explained “why the mere occurrence of the event identified . . .
    necessitat[ed] the continuance,” 
    id. at 1271
    , and it is “clear from the record that
    the trial court struck the proper balance [under the Speedy Trial Act] when it
    granted the continuance,” 33 Larson, 
    627 F.3d at 1206
     (quoting United States v.
    Williams, 
    511 F.3d 1044
    , 1056 (10th Cir. 2007)) (internal quotation marks
    omitted); see United States v. O’Connor, 
    656 F.3d 630
    , 639–40 (7th Cir. 2011)
    (reading an ends-of-justice continuance “in light of” earlier court orders, and
    concluding that the continuance was justified due in part to “the complexity of the
    case[ and] the magnitude of the discovery”); United States v. Bieganowski, 
    313 F.3d 264
    , 282 n.15 (5th Cir. 2002) (collecting cases and noting that “the decision

    Further, the amount of time given by the continuance is particularly
    reasonable when considering Mr. Gordon’s counsel’s own position in early 2009
    on the pace of the proceedings and the complexity of the case. In this regard,
    shortly after the district court filed its order granting the continuance, the
    government filed a status report and a motion for a scheduling conference,
    proposing a trial date of August 17, 2009. Mr. Gordon’s counsel promptly filed a
    responsive memorandum complaining that the case had advanced too quickly, and
    that counsel would only be amenable to a trial date commencing at the earliest in
    mid-October of 2009. The record here demonstrates that the length of the
    continuance permitted by the district court is clearly rooted in counsel’s
    averments to the court, and the expectation of the time it would take to “properly
    analyze the . . . transactions which [had to] be carefully pieced together” in order
    to present a “proper[] defen[se].” R., Vol. I, at 139 (David Gordon’s Mem. in
    Resp. to Government’s Status Report, filed Mar. 16, 2009). Mr. Gordon has
    offered no persuasive argument to the contrary.
    -71-
    to grant a continuance based on the volume of discovery[ is] consistent with cases
    interpreting section 3161(h)([7])”); cf. United States v. Napadow, 
    596 F.3d 398
    ,
    405–06 (7th Cir. 2010) (“While, of course, the record would have been more clear
    if the district court had identified precisely why the ends of justice served by
    granting the exclusion outweighed the best interest of the public and [the
    defendant] in a speedy trial, a comparison of the district court’s actual statements
    with the circumstances of the pretrial proceedings provide an adequate basis to
    justify the . . . exclusion.”).
    Finally, from the record, it appears that much of the time between January
    19, and April 5, 2010, was excludable under the Act because of pending motions
    and due to Mr. Gordon’s filing of an interlocutory appeal. As a threshold matter,
    Mr. Gordon has short-changed this portion of the analysis. Notably, he broadly
    claims in a conclusory and unsupported fashion that a total of 240 days passed
    “when no motions had been filed and no adequate justification had been given for
    the . . . delay.” Aplt. Opening Br. at 49. But he does not adequately identify
    whether this argument relates to any of the allegedly non-excludable days
    between January 19, and April 5, 2010, or only the period before that. Because it
    is not clear whether Mr. Gordon is specifically challenging the time period after
    January 19—viz., the time after the first ends-of-justice continuance ended—we
    would be well within our discretion to reject any of his nonspecific, unsupported
    assertions when considering this period. See Burrell, 
    603 F.3d at 835
    .
    -72-
    In any event, even were we to focus on the period from January 19 to April
    5, 2010, Mr. Gordon would not be entitled to relief. The Act excludes periods of
    delay “resulting from any interlocutory appeal,” 
    18 U.S.C. § 3161
    (h)(1)(C);
    accord 3B Charles Alan Wright & Peter J. Henning, Federal Practice and
    Procedure § 835, at 434, 436 & n.17 (4th ed. 2013), and those “resulting . . . from
    the filing of [any pre-trial] motion through the conclusion of the hearing on, or
    other prompt disposition of, such motion,” 
    18 U.S.C. § 3161
    (h)(1)(D); see also
    United States v. Tinklenberg, 
    131 S. Ct. 2007
    , 2012 (2011) (noting that the
    provision in § 3161(h)(1) regarding pre-trial motions applies “irrespective of
    whether the motion has any impact on when the trial begins”). Even if the
    appropriate calculations are completed for this period, according to the
    government’s account of the litigation—which Mr. Gordon does not
    challenge—the total non-excludable time falls far short of the seventy-day limit.
    Put another way, when the total number of elapsed days between the unsealing of
    the indictment and the start of the trial is reduced by the total number of
    statutorily excludable days, the product (i.e., the difference) of non-excludable
    days is considerably less than the seventy days that the Act permits to run. 34
    34
    We note that the circuits are not uniform in their calculation of
    excludable days with respect to pre-trial motions; more specifically, the variance
    relates to whether to deem the filing or disposition date of motions excludable
    time. See Williams, 
    511 F.3d at
    1051 n.5 (collecting cases and noting the lack of
    uniformity regarding this pre-trial motion calculation under then § 3161(h)(1)(F)).
    (continued...)
    -73-
    For the foregoing reasons, Mr. Gordon has not shown a violation of the
    Speedy Trial Act.
    F.    Sentencing
    Mr. Gordon lodges numerous challenges to his sentence, specifically
    relating to the district court’s loss and gain calculations and its imposition of joint
    and several liability for the illicit stock sales. Broadly, Mr. Gordon appears to
    make two, separate procedural challenges to his sentence. First, he contends that
    the district court inappropriately based its measure of harm in this case
    “exclusively on the differences in the cost of the four stocks purchased by a group
    of persons oftentimes loosely linked to [him] and the amount each of those
    various parties sold their stock for,” Aplt. Opening Br. at 51, and failed to take
    into consideration “other economic factors unrelated to the defendant’s fraudulent
    activity that may have caused the stock to increase or decrease,” id. at 52. 35 This,
    34
    (...continued)
    Apparently, “we have not directly addressed the issue.” Id. However, regardless
    of how the excludable time is calculated—viz., by including the date the motion is
    filed and its disposition date, or by excluding either or both dates—our ultimate
    conclusion would remain the same. Mr. Gordon was tried within the seventy
    (non-excludable) days that the Act permitted.
    35
    The government has filed a motion to supplement the record under
    seal with multiple sentencing documents not included in the parties’ appellate
    appendices. Among these documents are earlier, provisional versions of Mr.
    Gordon’s PSR and the district court’s Statement of Reasons for imposing
    sentence. Mr. Gordon objects to the inclusion of the provisional PSRs without
    the attachment of e-mails sent between his counsel and the U.S. Probation Office.
    (continued...)
    -74-
    he reasons, was “procedural error” in the determination of his sentence, insofar as
    it concerns the application of the twenty-two-level enhancement under
    § 2B1.1(b)(1). Id. at 50. Second, he contends that the “damage[s] calculation
    should be individual, rather than joint” in cases like his, where the court
    attributed stock sales made by others who were at best only “tenuously affiliated”
    with him. Id. at 54. And, in the latter respect, he takes issue with the district
    court’s attribution of others’ illicit “gain” to him for purposes of “relevant
    conduct” under the Guidelines.
    “[S]entences are reviewed ‘under an abuse of discretion standard for
    procedural and substantive reasonableness.’” United States v. Snow, 
    663 F.3d 1156
    , 1160 (10th Cir. 2011) (quoting United States v. Washington (Wildor
    Washington), 
    634 F.3d 1180
    , 1184 (10th Cir. 2011)). “[W]e review the district
    court’s legal conclusions de novo and its factual conclusions for clear error.”
    Gallant, 
    537 F.3d at 1234
    . “A sentence is procedurally unreasonable if the
    district court incorrectly calculates or fails to calculate the Guidelines sentence,
    treats the Guidelines as mandatory, fails to consider the [18 U.S.C.] § 3553(a)
    factors, relies on clearly erroneous facts, or inadequately explains the sentence.”
    35
    (...continued)
    He does not, however, object to the inclusion of the district court’s Statement of
    Reasons. We grant the motion with respect to the Statement of Reasons, but
    because the PSR relied upon by the district court is already a part of the record,
    we see no need to consider earlier, provisional versions of it. Consequently, we
    deny the government’s motion to consider such versions of the PSR.

    other words, “we may disturb the district court’s loss determination—and
    consequent Guidelines enhancement—‘only if the court’s finding is without
    factual support in the record or if, after reviewing all the evidence, we are left
    with a definite and firm conviction that a mistake has been made.’”

    Aquila, Inc. v. C.W. Mining, 
    545 F.3d 1258

    the district court’s “loss calculation methodology” is reviewed de novo. Snow,
    -76-
    
    663 F.3d at 1160
     (quoting Wildor Washington, 
    634 F.3d at 1184
    ) (internal
    quotation marks omitted).
    In this case, the district court determined that it would be too difficult to
    determine the actual losses suffered by each individual investor affected by the
    conspirators’ manipulation scheme. Thus, consistent with § 2B1.1, comment note
    3(B), of the Guidelines, it calculated an alternative measure of illicit gain. See
    U.S.S.G. § 2B1.1, cmt. n.3(B) (“The court shall use the gain that resulted from
    the offense as an alternative measure of loss only if there is a loss but it
    reasonably cannot be determined.”). In doing so, however, it first attempted (for
    comparative purposes) to make reasonable estimates of the total losses to
    investors, given the information available.
    In calculating the loss estimates, the court utilized two separate methods.
    First, it subtracted the average price of each stock after disclosure of the fraud
    from the stock’s average price during the promotional period. Then, it multiplied
    by the total number of shares sold. This method yielded a loss estimate of
    $55,150,000. Alternatively, the court subtracted the inherent value of the stocks
    from their average value during the promotional period, yielding a loss estimate
    of $47,240,000. 36
    36
    In United States v. Nacchio, 
    573 F.3d 1062
    , 1075 (10th Cir. 2009),
    we described “a stock’s inherent value” as “the market’s assessment of the stock’s
    value, reflecting primarily the value of the firm’s net assets and operations and its
    (continued...)
    -77-
    The court then went on to calculate the total conspiratorial gain from the
    manipulation of National Storm, Deep Rock, and Global Beverage to be
    $43,927,809.95, and Mr. Gordon’s gain attributable to sales of IPG to be
    $2,714,504, 37 and determined that those calculations corresponded to the loss
    estimates, see Snow, 
    663 F.3d at 1161
     (“The defendant’s gain may be used only
    as an alternate estimate of . . . loss; it may not support an enhancement on its own
    if there is no actual or intended loss to the victims.” (quoting Wildor Washington,
    
    634 F.3d at 1184
    )) (internal quotation marks omitted)). We have endorsed the
    base approach utilized by the district court in analogous contexts—viz., using gain
    as an alternative measure of loss where loss cannot be reliably ascertained,
    provided that the court first makes a reasonable estimate of loss. See United
    States v. Galloway, 
    509 F.3d 1246
    , 1252 (10th Cir. 2007) (“[B]efore using gain as
    an alternate estimate of loss, the district court must first estimate the actual and
    intended loss due to a defendant’s fraudulent conduct, and then consider whether
    the defendant’s gain is a reasonable estimate of the actual or intended loss.”); cf.
    36
    (...continued)
    potential earnings and growth prospects.” This would be the value that a stock
    holds without reference to any fraudulent conduct of the defendant.
    37
    The conduct concerning IPG was not a part of the government’s
    general conspiracy allegations, so the court simply added the proceeds realized
    from the fraudulent sale of IPG stock to the gains computed for National Storm,
    Deep Rock, and Global Beverage under the Guidelines grouping rules in § 3D1.3.
    Mr. Gordon’s sentencing challenges on appeal deal primarily with the gain
    computations relating to the latter stocks, not IPG’s.
    -78-
    Gallant, 
    537 F.3d at
    1236–38 (holding that the district court improperly failed to
    calculate reasonable estimates of loss in arriving at an alternative gain figure in a
    financial-fraud scheme).
    Mr. Gordon does not necessarily challenge the court’s findings under the
    foregoing methodology; rather, he contends that the court should have also
    considered other potential causes of fluctuations in the applicable share prices of
    National Storm, Deep Rock and Global Beverage—for instance, the rising price of
    gas during the promotional period, the natural disasters that occurred during the
    holding period, etc.—and because the testimony that the district court relied upon
    did not necessarily take those factors into account, the resulting gain figures were
    erroneously obtained. In essence, Mr. Gordon challenges the inputs utilized by
    the district court, reasoning that the court failed to consider the “economic
    reality” of his conduct as required by our decision in Nacchio. 38
    38
    Although it might logically seem appropriate to apply Nacchio’s
    sentencing paradigm in the pump-and-dump context, it does not appear to be
    settled in our circuit whether Nacchio applies outside of the insider trading
    context. See 
    573 F.3d at 1086
     (noting that “district courts must undertake
    ‘thorough analyses grounded in economic reality,’ when sentencing defendants in
    insider trading cases” (emphasis added) (citation omitted) (quoting United States
    v. Olis, 
    429 F.3d 540
    , 547 (5th Cir. 2005))). While other courts have applied
    Nacchio-type inquiries in the pump-and-dump context, see United States v. Zolp,
    
    479 F.3d 715
    , 719 (9th Cir. 2007), Mr. Gordon has pointed to no Tenth Circuit
    case extending it to that context. However, given that we conclude that Mr.
    Gordon’s Nacchio argument is unavailing, we may assume without definitively
    deciding that Nacchio’s sentencing principles apply with full force in the pump-
    and-dump context.
    -79-
    In Nacchio, we held that, when calculating a gain amount under the
    Guidelines in insider trading cases, the district court should utilize “[a]n approach
    that focuses on arriving at a figure that approximates the gain specifically
    resulting from [the] offense,” which necessitates an inquiry into “the myriad of
    factors unrelated to [the] criminal fraud that could have contributed to the
    increase in the value of the securities.” 
    573 F.3d at 1074
     (emphasis added).
    More specifically, we held that “district courts must undertake ‘thorough analyses
    grounded in economic reality.’” 
    Id. at 1086
     (quoting Olis, 
    429 F.3d at 547
    ).
    Here, in arriving at its conclusions, the district court explicitly cited Nacchio, and
    stated that it was in fact considering the “economic reality” of the transactions at
    issue in its underlying analysis. See R., Vol. VIII, at 2795 (applying “[m]ultiple
    methods of calculating loss . . . [which we]re rooted in ‘economic reality’”). Mr.
    Gordon concedes as much. See Aplt. Reply Br. at 28 (“Appellant acknowledges
    the district court stated at sentencing [that] it had considered this court’s
    sentencing factors for a securities fraud case in [Nacchio].”).
    To be sure, the district court did not explain how any of the extraneous
    factors that Mr. Gordon identifies on appeal affected the stock sales of National
    Storm, Deep Rock, and Global Beverage. 39 However, by its plain dictate,
    39
    We are doubtful that Mr. Gordon presented this argument before the
    district court in the context in which he now raises it on appeal. That is, he
    appears not to have argued that the district court should have, in its ultimate
    (continued...)
    -80-
    Nacchio does not require the court to employ an empirical inquiry that takes
    account of the effect of every conceivable variable that could possibly affect a
    defendant’s gain from an illicit stock sale. Rather, it requires the court to “adopt
    a sentencing approach that is focused on a defendant’s criminally culpable
    conduct and has the effect of excising . . . unrelated market forces from the
    sentencing calculus, thereby narrowing the zone of unpredictability in
    sentencing.” Nacchio, 
    573 F.3d at 1082
    . Yet this “excisi[on]” need not be
    absolutely “complete[].” Id.; see also U.S.S.G. § 2B1.1 cmt. n.3(C) (“The court
    need only make a reasonable estimate of the loss.” (emphasis added)). It must
    only ensure, as an overarching matter, that a defendant’s punishment “reflects his
    . . . culpability for the criminal offense (rather than for unrelated gyrations of the
    market).” Nacchio, 
    573 F.3d at 1077
    . What was contemplated in Nacchio was
    not the complete elimination of “chance market forces” from a gain calculation,
    but merely the “minimiz[ation of] the influence of factors other than a
    defendant’s unlawful acts on the calculation of punishment.” 
    Id.
     at 1086 n.23.
    Significantly, in Nacchio, we suggested that unrelated market events were
    39
    (...continued)
    calculations, considered specifically identified non-fraud related factors in
    applying the enhancement under § 2B1.1(b)(1)(L). However, the government
    does not contend that Mr. Gordon failed to preserve this issue (that is, that Mr.
    Gordon forfeited it). Therefore, we exercise our discretion under the particular
    circumstances presented here to ignore the possible lack of preservation.

    material only insofar as they “c[ould] be identified” and assessed. See id. In this
    regard, it is notable that Mr. Gordon has not suggested that the district court
    actually had evidence in the record to identify, and consider the effects of, the
    alternative variables that he advocates for here. In fact, in his formal objections
    to the PSR, Mr. Gordon “agree[d] that there is insufficient evidence in the record
    to separate out the impact of legitimate market factors on the price of each stock
    and quantify the impact of the promotional schemes.” R., Vol. VI, at 623 n.7
    (Letter from Thomas O. Gorman to Scott Kallenberger, dated Aug. 2, 2010)
    (setting out Mr. Gordon’s formal objections to the PSR). Thus, we would be
    hard-pressed to conclude that the district court committed reversible error in not
    identifying, and assessing the impact of extrinsic variables, when there was no
    foundation in the record for it to do so. 40
    40
    Mr. Gordon does not contend that filling such purported evidentiary
    holes was the government’s burden and that, consequently, any deficiencies in the
    district court’s ruling must be laid at the government’s feat. Indeed, Mr. Gordon
    tacitly suggests that he bore at least a portion of the burden to come forward with
    evidence regarding such non-fraud factors. In this regard, he complains that he
    might have filled any purported evidentiary holes, if the court had allowed him
    access to substitute assets; with them, he allegedly could have hired an economic
    expert to fill the holes. Although the question of burden of proof regarding the
    identification of extrinsic, non-fraud factors does not appear to have been
    explicitly addressed in Nacchio, the authorities upon which its analysis is founded
    seem to have placed this burden on the defendant. See Nacchio, 
    573 F.3d at 1085
    (relying, inter alia, on SEC v. First City Fin. Corp., 
    890 F.2d 1215
    , 1232 (D.C.
    Cir. 1989)). Because of Mr. Gordon’s silence on the issue, however, we need not
    resolve the matter in this case. Furthermore, even if Mr. Gordon’s experts could
    have filled the purported holes in the record, for reasons explicated below, we
    (continued...)
    -82-
    In any event, even if the district court committed some error, as the
    government argues, it would be harmless. See Aplee. Br. at 64 (“In any event, the
    loss calculation did not affect Gordon’s sentence.”). Although Mr. Gordon points
    to some factors that the district court conceivably could have considered, he does
    not explain how those factors would have materially affected the district court’s
    sentencing calculations. In this vein, the district court found that the government
    had made an adequate showing of the conspiratorial gain amount by virtue of its
    trial evidence. Mr. Gordon has not identified how the court’s calculations would
    have been changed, or how any variable would have necessarily lowered the total
    gain calculation to an amount that is less than $20,000,000—i.e., the trigger under
    § 2B1.1(b)(1)(L) for the twenty-two-level enhancement that the district court
    ultimately applied. And, on the basis of this record, we cannot discern any
    support for such a proposition. Furthermore, as the government suggests, the
    district court “made clear that its sentence was not driven by the loss calculation
    and corresponding Guidelines range,” id., given that it expressed dissatisfaction
    with the severity of the Guidelines in securities fraud cases and granted Mr.
    Gordon a very substantial downward variance, see R., Vol. VIII, at 2824–25
    (finding that “a downward variance . . . provides for an appropriate sentence” and
    40
    (...continued)
    cannot conclude that the district court’s sentencing computations would have been
    materially altered.
    -83-
    noting that ranges specified by the securities fraud Guidelines “are patently
    absurd on their face.”). Mr. Gordon has not alleged that the district court would
    have varied downward even further, but for any alleged error in computing his
    Guidelines range. In sum, we conclude that Mr. Gordon’s sentencing challenge
    must fail: we discern no error in the district court’s Guidelines gain computations
    and, even if it did err, such error was harmless.
    2.     Joint Liability and Relevant Conduct
    Mr. Gordon also contends that the district court should have held him
    responsible at most for his own trading profits, and not the profits linked to other
    alleged co-conspirators. In that respect, he argues that “this is a good case for the
    court to find that the damage calculation should be individual, rather than joint.”
    Aplt. Opening Br. at 54.
    Our review of the record demonstrates that Mr. Gordon did raise a version
    of this argument below, though he certainly has not helped himself in his cursory
    treatment of the issue on appeal. In any event, we may easily dispose of Mr.
    Gordon’s challenge to the district court’s decision to attribute to him the gains of
    alleged co-conspirators in determining his offense level under § 2B1.1. “U.S.S.G.
    § 1B1.3(a)(1)(B) provides that a defendant involved in a joint criminal
    undertaking may be held responsible for relevant conduct that includes all
    reasonably foreseeable conduct of his co-conspirators that is in furtherance of the
    -84-
    conspiracy.” United States v. Offill, 
    666 F.3d 168
    , 180 (4th Cir. 2011); see
    United States v. Treadwell, 
    593 F.3d 990
    , 1002 (9th Cir. 2010) (“Where the
    amount of loss is the result of ‘jointly undertaken criminal activity’—such as a
    conspiracy—the relevant amount of loss must be determined on the basis of ‘all
    reasonably foreseeable acts and omissions of others in furtherance of the jointly
    undertaken criminal activity, that occurred during the commission of the offense
    of conviction.’” (quoting U.S.S.G. § 1B1.3(a)(1)(B))); see also United States v.
    Griffith, 
    584 F.3d 1004
    , 1011 (10th Cir. 2009) (“In calculating loss under the
    Guidelines, the district court does not limit itself to conduct underlying the
    offense of conviction, but rather may consider all of the defendant’s ‘relevant
    conduct’ [under § 1B1.3].” (quoting U.S.S.G. § 1B1.3)).
    Application Note 3(B) to § 2B1.1 states that the court “shall use the gain
    that resulted from the offense” where loss cannot be calculated, U.S.S.G. § 2B1.1
    cmt. n.3(B)—as, of course, the district court in this case did. “The use of the
    word ‘offense’ when applied here refers to the conspiracy.” Offill, 
    666 F.3d at 180
    . As long as the gain of a co-conspirator is reasonably foreseeable, it can be
    attributed to a defendant. See 
    id.
     (citing cases).
    Thus, to the extent that Mr. Gordon contests as a matter of law the district
    court’s use of a joint calculation in computing his gain, his argument lacks merit.
    Indeed, courts have consistently held that reasonably foreseeable gains
    -85-
    attributable to co-conspirators’ acts are properly tabulated in § 2B1.1(b)(1)’s
    offense-conduct computations. See, e.g., id. (collecting cases and holding that the
    district court did not err in imputing co-conspirators’ gains to a defendant in a
    pump-and-dump scheme in calculating his offense level under § 2B1.1(b)(1)).
    And the record here demonstrates that the district court had an adequate factual
    basis on which to attribute all of the relevant conspiratorial conduct at issue to
    Mr. Gordon for sentencing purposes. 41 See United States v. Lewis (Charles
    Lewis), 
    594 F.3d 1270
    , 1290 (10th Cir. 2010) (concluding that a co-conspirator’s
    fraudulent conduct was financial in nature and was therefore reasonably
    foreseeable to the defendant as part of a ponzi scheme, where the defendant
    played an extensive role in the scheme); see also United States v. Sells, 
    541 F.3d 41
    Mr. Gordon also challenges, in passing, that the “list of ‘associates’
    compiled by Agent [Jarom] Gregory to inflate the overall damage calculation”
    was improperly applied to him because it included individuals like Robert
    Garner—the president of Deep Rock—who did “nothing more than work in the
    same office building with [Mr. Gordon].” Aplt. Opening Br. at 54. His briefing
    on this issue is woefully inadequate. While he singles out Mr. Garner in
    illustration, and makes a vague and generalized reference to “several others like
    him who had been tenuously affiliated” with Mr. Gordon, 
    id.,
     he does not begin to
    describe the factual or legal bases for a conclusion that it was error to take into
    account any of the individuals (including Mr. Garner) for purposes of calculating
    relevant conduct. In essence, this argument is conclusory and offers no proper
    foundation for appellate review. Therefore, we will not examine it further. See,
    e.g., United States v. Pursley, 
    577 F.3d 1204
    , 1228 (10th Cir. 2009) (“[The
    defendant] does not cite a single case to support his position. Consequently, we
    are free to end our inquiry by applying the principle that ‘[a]rguments
    inadequately briefed in the opening brief are waived.’” (second alteration in
    original) (quoting Adler, 
    144 F.3d at 679
    )).

    332 F.3d 1307
    , 1311 (10th
    Cir. 2003); United States v. Tagore,

    , 1128–30 (10th Cir. 1998);
    United States v. McFarlane, 
    933 F.2d 898
    , 899 (10th Cir. 1991). For these
    reasons, we reject Mr. Gordon’s joint-and-several argument.
    G.    Final Order of Forfeiture
    Mr. Gordon lastly argues that the district court failed to follow the dictates
    of 
    21 U.S.C. § 853
    (p) in issuing a final forfeiture order. “[W]e review the district
    court’s forfeiture order as we would any other sentencing determination—that is,
    we review its legal conclusions de novo and its factual findings for clear error.”
    United States v. Bader, 
    678 F.3d 858
    , 893 (10th Cir. 2012); see Libretti v. United
    States, 
    516 U.S. 29
    , 38–39 (1995) (“Forfeiture is an element of the sentence
    imposed following conviction . . . .” (emphasis omitted)). “A forfeiture judgment
    must be supported by a preponderance of the evidence.” Bader, 
    678 F.3d at 893
    .
    On January 11, 2011, upon the government’s motion, the district court
    ordered the forfeiture of various interests Mr. Gordon held in real property and
    financial instruments as “substitute property” pursuant to Federal Rule of
    Criminal Procedure 32.2 and 
    21 U.S.C. § 853
    (p). 42 The order was entered
    subsequent to the district court’s entry of a joint and several money judgment in
    the amount of $2,747,761.81, individually against Mr. Gordon for the IPG wire
    42
    These included shares of various companies, the “Delvest” lots, and
    other accounts.
    -87-
    fraud scheme, and $43,927,809.95 representing proceeds traceable to the criminal
    acts at issue.
    Rule 32.2(e)(1)(B) authorizes the government to move for an order of
    forfeiture, or to “amend an existing order,” to include property that “is substitute
    property that qualifies for forfeiture under an applicable statute.” As relevant
    here, the criminal forfeiture statute provides that a defendant’s substitute property
    may be forfeited where,
    as a result of an act or omission of the defendant [the forfeited
    property]-- (A) cannot be located upon the exercise of due
    diligence; (B) has been transferred or sold to, or deposited with,
    a third party; (C) has been placed beyond the jurisdiction of the
    court; (D) has been substantially diminished in value; or (E) has
    been commingled with other property which cannot be divided
    without difficulty.
    
    21 U.S.C. § 853
    (p)(1)(A)–(E). Forfeiture “shall” be ordered “up to the value of
    any property described.” 
    Id.
     § 853(p)(2).
    In support of its second motion for forfeiture, the government offered the
    affidavit of Litigation Financial Analyst William Robert Taylor, who averred that
    he had conducted a full financial investigation of Mr. Gordon’s business and
    personal accounts. Section 853(p)(1), by its express terms, permits the forfeiture
    of substitute assets, when directly traceable assets cannot be located despite the
    exercise of due diligence, because of an act or omission of the defendant. See,
    e.g., Bornfield, 
    145 F.3d at 1139
     (“The substitute assets provision allows the
    -88-
    forfeiture of other assets not already forfeitable when the forfeitable asset is
    unavailable due to some act or omission of the defendant.”). Mr. Taylor
    specifically averred that “[d]ue to acts or omissions of [Mr. Gordon], additional
    property directly traceable to the conspiracy . . . is unavailable for forfeiture.” R.,
    Vol. VI, at 1101 (Aff. of William Robert Taylor, signed Nov. 19, 2010).
    Similarly, the affidavit set forth that law enforcement personnel “have been
    unable to locate, through the exercise of due diligence, any other assets . . . that
    are traceable to the offenses.” 
    Id.
     at 1101–02.
    Because the directly forfeitable “assets” previously identified consisted
    largely of a now uncontested money judgment, and the money could not be found
    in Mr. Gordon’s accounts, it was reasonable for Mr. Taylor to infer, and the
    district court to find, that the money was dissipated due to Mr. Gordon’s conduct.
    Indeed, given the transactional nature of a large-scale securities fraud conspiracy,
    vast sums of money are easily transferred or hidden. The evidence in this case
    demonstrated that, as part of the conspiratorial plan, funds used to purchase
    stocks were frequently decentralized and concealed.
    “The Government generally has little difficulty in making the necessary
    showing [under § 853(p)].” Stefan D. Cassella, Asset Forfeiture Law in the
    United States § 22-3, at 643 (2007) (collecting cases); see United States v. Garza,
    407 F. App’x 322, 324–25 (10th Cir. 2011) (relying on language asserting that the
    -89-
    government exercised due diligence in attempting to located forfeitable assets
    under § 853(a) in concluding that the government met its burden of establishing
    the requirements of § 853(p)); see also United States v. Alamoudi, 
    452 F.3d 310
    ,
    316 (4th Cir. 2006) (concluding that the affidavit was sufficient to support
    forfeiture under § 853(p) where it contained information that, based on the
    investigator’s experience, the “acts” or “omissions” of the defendant made the
    proceeds unavailable); United States v. Candelaria-Silva, 
    166 F.3d 19
    , 42–43 (1st
    Cir. 1999) (holding that the government complied with § 853(p)’s requirements
    where it submitted an affidavit that “recited the efforts [it] had made to locate the
    proceeds of the . . . conspiracy” and concluded that the defendant had disposed of
    those proceeds); United States v. Faulk, 
    340 F. Supp. 2d 1312
    , 1315 (M.D. Ala.
    2004) (finding that the government met its burden under § 853(p)(1) where it
    “show[ed] that . . . laundered money ha[d] been substantially dissipated due to the
    dispersion of funds by the defendants themselves”); cf. United States v. Gregoire,
    
    638 F.3d 962
    , 972 (8th Cir. 2011) (holding that there was no evidence that
    forfeitable property was made unavailable by an act of the defendant, because it
    was in the government’s possession). Here, despite posing general, rhetorical
    questions in attempting to construct an argument, see, e.g., Aplt. Opening Br. at
    56 (“Had Appellee knocked on Tommy Gambino’s door to ask him if he still had
    any of the illicit proceeds attributable to him?”), Mr. Gordon offers no reasonable
    basis to dispute or otherwise contradict the averments in Mr. Taylor’s affidavit
    -90-
    that the government exercised due diligence in seeking to locate the directly
    forfeitable funds at issue and that they were missing due to an act or omission of
    Mr. Gordon.
    Mr. Gordon further contends that the district court erred in finding in its
    preliminary orders of forfeiture that the government had satisfied the
    requirements of § 853(p)(2), which, upon a proper showing under § 853(p)(1),
    requires the court to “order the forfeiture of any other property of the defendant.”
    Mr. Gordon complains that the government simply did not show that (1) his
    personal “residence” belonged to him (i.e., because it was in his wife’s name) and
    (2) that many of the other identified assets belonged to him.
    Contrary to Mr. Gordon’s suggestions, the Gordon residence was not
    ordered forfeited entirely as “substitute property.” Rather, the court found
    $1,702,000 of equity in the home directly forfeitable under 
    18 U.S.C. § 981
    (a)(1)(C) and 
    28 U.S.C. § 2461
    (c). Mr. Gordon’s brief does not appear to
    challenge the propriety of this direct forfeiture. Mr. Gordon’s other challenges
    are non-specific and conclusory, which yet again compels us to decline searching
    review. However, we note that third-party ownership disputes are generally
    “deferred to . . . ancillary proceeding[s] [under § 853(n)] and do not factor into
    the court’s determination whether to order the forfeiture of the property in the
    first instance.” Cassella, supra, § 22-3, at 645; see Fed. R. Crim. P. 32.2(c)(1);
    -91-
    Baranski v. Fifteen Unknown Agents of Bureau of Alcohol, Tobacco & Firearms,
    
    452 F.3d 433
    , 462–63 (6th Cir. 2006) (en banc) (Clay, J., dissenting) (suggesting
    that a third party must assert his or her interest in property adjudicated to be
    forfeitable in ancillary proceedings). “At [the forfeiture] stage the court does
    not—and, indeed, may not—determine the rights of any third parties who assert
    an interest in the property. Third parties . . . have an opportunity to assert their
    rights to the property in an ‘ancillary proceeding’ . . . .” 43 United States v.
    Andrews, 
    530 F.3d 1232
    , 1236 (10th Cir. 2008) (citations omitted) (quoting Fed.
    R. Crim. P. 32.2(c)); see United States v. Musson, 
    802 F.2d 384
    , 386 (10th Cir.
    1986) (“Appellants’ concerns regarding potential third party interests in the
    subject property are also addressed by a provision for subsequent third party
    petitions to the court.” (citing, inter alia, 
    21 U.S.C. § 853
    (n))); Cassella, supra,
    § 22-3, at 645–46 (“[T]he court does not determine that [a] substitute asset
    belongs to the defendant when it includes it in the preliminary order of forfeiture;
    rather, the requirement in § 853(p)(2) that the substitute asset be ‘property of the
    defendant’ is satisfied by allowing third parties to contest the forfeiture of the
    43
    Indeed, in the district court’s final order of forfeiture it is clear that
    an unidentified ancillary claimant “consented and stipulated to the entry of [the]
    final order” with regard to the Gordon residence. R., Vol. VI, at 1224 (Dist. Ct.
    Final Order of Forfeiture of Real Property & Funds in Financial Accounts, filed
    Feb. 16, 2011). The record thus demonstrates that ancillary proceedings were
    held, and Mr. Gordon has not explained the substance of any determination made
    in those proceedings, much less demonstrated error.
    -92-
    property in the ancillary proceeding pursuant to § 853(n) and Rule 32.2(c).”).
    Thus, we reject Mr. Gordon’s arguments to the extent that they challenge the
    district court’s preliminary forfeiture orders and their effect on third-party
    interests. In sum, we conclude that the government offered sufficient evidence to
    make the required showings under § 853(p)(1) and (p)(2) and that the district
    court did not err in issuing its orders of forfeiture.
    III. Conclusion
    For the foregoing reasons, we AFFIRM Mr. Gordon’s conviction and
    sentence, including the district court’s orders of forfeiture.
