    convicted of one count of conspiracy to commit securities fraud in violation of
    18 U.S.C. §§ 2 and 371 and two counts of securities fraud in violation of 15
    U.S.C. §§ 78j(b) and 78(ff). On appeal, Liu challenges the sufficiency of the
    evidence supporting her conviction. She also contends the district court abused
    its discretion in denying her a severance. Concluding that the evidence was

    sufficient and that the district court did not abuse its discretion in denying a
    severance, we AFFIRM.
    I. FACTUAL AND PROCEDURAL BACKGROUND
    Viewed in the light most favorable to the verdict, the relevant facts are
    as follows. 2 In March 2012, Chicago Bridge and Iron, N.C. (“CB&I”) expressed
    interest in acquiring The Shaw Group (“Shaw”). Both companies were publicly
    traded, and both had approximately $6 billion in revenue. By May 2012,
    Toshiba Corporation (“Toshiba”) became interested in joining CB&I, and the
    two companies approached Shaw to discuss an acquisition. The next two
    months saw both sides hurriedly conduct their due diligence to obtain
    information in preparation for the possible acquisition. At some point prior to
    July 4, 2012, Toshiba dropped out, but CB&I never wavered in its negotiations
    to acquire Shaw. On July 4, 2012, Shaw and CB&I reached a tentative deal,
    and after final due diligence, CB&I on July 30, 2012 announced its agreement
    to acquire Shaw.
    Defendant-appellant Kelly Liu (“Liu”) took an active role in obtaining
    Shaw’s financial information to satisfy CB&I’s due diligence requests. Liu had
    been in Shaw’s five-person Financial Planning & Analysis Group (FP&A) since
    2011. As such, Liu was no stranger to due diligence; she had worked on several
    of Shaw’s acquisitions of smaller companies. Her group regularly assisted with
    market analysis and due diligence for these acquisitions, and thus became
    familiar with the high level of secrecy involved in handling this information.
    Because of her access to restricted information, Shaw considered her an
    “insider” and provided her and others in her department the company’s policy
    on insider trading.

    No. 18-31299
    As Liu and her team conducted final due diligence in the weeks leading
    up to the closing, Liu’s codefendants purchased Shaw stocks and call options.
    The trial centered on the actions of Liu, together with Salvador “Sammy”
    Russo, III (“Russo”), Diemo Ho (“Diemo”), and Victory Nam Ho (“Vic”).
    Codefendant Russo was Liu’s live-in boyfriend at the time of the offense. The
    two had been dating since 2006. Diemo was their neighbor and Liu’s close
    friend. Codefendant Vic was Diemo’s older brother and an acquaintance of
    Liu’s. 3
    From July 18 to 27, 2012, a flurry of communications occurred between
    the above parties. Call records revealed a pattern: Liu and Diemo would
    communicate by phone or text, Diemo would immediately thereafter phone or
    text Vic, and Diemo would then quickly phone or text Liu. Conversations
    peaked on the days Vic and Russo purchased stocks and options in Shaw; the
    communications between the parties throughout July were strikingly high.
    During some of these conversations, IP addresses 4 used by Liu and Diemo
    accessed Vic’s brokerage account to investigate Shaw stock price. Russo
    directed his mother to purchase stocks on July 19, 2012, and Vic purchased his
    Shaw call options eight days later. When Vic purchased his options, he wrote
    to a representative of optionsXpress in a recorded online chat to confirm that
    he could sell the options on July 30, 2012, the day Shaw announced the
    acquisition.
    Following the July 30 announcement of CB&I’s purchase of Shaw, the
    price of Shaw stock rose roughly $15 per share. Within forty minutes of the
    announcement, the parties again communicated back and forth. Russo held
    onto the stock in his mother’s account, eventually making a $2800 cash profit.

    Vic, meanwhile, sold his Shaw call options on July 30 for a profit of $294,000
    (over 3500% in gains).
    When Vic filed his 2012 tax returns, he failed to report these profits
    despite receiving a 1099 tax form. After his tax preparer reminded him to pay
    taxes on gains, Vic responded that he was “in trouble,” but he did not seek to
    amend his 2012 return. During trial, the district court provided limiting
    instructions to the jury regarding their consideration of the evidence of Vic’s
    failure to report his capital gains when evaluating the charges against Liu.
    The indictment charged Liu with committing insider trading and
    entering into a conspiracy with Russo and Vic to do so. Before trial, the district
    court rejected Liu’s pre-trial motion for severance, and the motion was re-urged
    and denied at every available opportunity. Liu filed her timely notice of appeal
    a week after the court imposed her sentence of sixteen months per count to run
    concurrently.
    II. DISCUSSION
    A. Insider Trading Elements
    Section 10(b) of the Securities Exchange Act of 1934 and the Securities
    and Exchange Commission’s Rule 10b-5 impose civil and criminal liability for
    insider trading. The Act “prohibit[s] undisclosed trading on inside corporate
    information by individuals who are under a duty of trust and confidence that
    prohibits them from secretly using such information for their personal
    advantage.” 5 In Dirks v. SEC, the Supreme Court held that when a corporate
    insider shares material, nonpublic information with someone in breach of his
    or her fiduciary duty for personal gain, the corporate insider may be held liable
    as a “tipper.” 6

    137 S. Ct. 420
    , 423 (2016); see 15 U.S.C. §§ 78j, 78ff; 17
    C.F.R. §§ 240.10b-5.

    No. 18-31299
    Consistent with Supreme Court precedent, the district court instructed
    the jury of the following six elements required to convict a tipper of insider
    trading: (1) that the defendant disclosed material, nonpublic information to
    another person, (2) that the disclosure was made for personal purpose in
    breach of the defendant’s fiduciary duty as a corporate insider, (3) that the
    defendant anticipated that the other person would trade on the basis of the
    information, (4) that the other person unlawfully traded, (5) that the defendant
    acted knowingly, willfully, and with the intent to defraud, and (6) that the
    insider trading scheme involved the use of some instrumentality of interstate
    commerce. 7
    1. Sufficiency of the Evidence
    This court reviews preserved challenges to the sufficiency of the evidence
    de novo. 8 “Though de novo, this review is nevertheless highly deferential to the
    verdict.” 9 Under this standard, “the relevant question is whether . . . any
    rational trier of fact could have found the essential elements of the crime
    beyond a reasonable doubt.” 10 This court must “view the evidence in the light
    most favorable to the verdict and draw all reasonable inferences from the
    evidence to support the verdict.” 11 “Determining the weight and credibility of
    the evidence is within the sole province of the jury.” 12
    7  On appeal, Liu does not challenge the jury instructions, which accurately set forth
    the elements of tipper liability for insider trading. See 
    Salman, 137 S. Ct. at 423

    No. 18-31299
    Liu challenges the sufficiency of the evidence to establish that she
    possessed and disclosed material, nonpublic information, and that she acted
    with scienter to support her conviction for insider trading. She also challenges
    the sufficiency of the evidence to show that she conspired with her
    codefendants to commit insider trading. Each of these issues will be discussed
    in turn.
    a. Possession
    Liu first argues that the evidence was insufficient to show that she
    possessed any information concerning the buyout. Specifically, she stresses
    that she merely had potential access to information, which is insufficient to
    establish possession.
    The Government, however, presented evidence showing that Liu
    deduced that an acquisition was about to occur. On May 29, 2012, Liu received
    CB&I and Toshiba’s 22-page due diligence request for “Project Jewel,” a code
    name for the acquisition. This was followed by a number of other requests for
    additional information. CFO Brian Ferraioli testified that a member of FP&A
    “could easily have inferred” from the due diligence requests that a company
    was seeking to purchase Shaw. In addition, FP&A Manager Rebecca Wallace
    testified that she and Liu took a private phone call from a Morgan Stanley
    investment banker on July 16, 2012 while at lunch, discussing “sensitive
    information” concerning EBITDA (an important metric for a buyout). 13 Wallace
    stated it was “pretty easy to guess” what was happening, both from the
    involvement of investment bankers and the inquiry about EBITDA. Liu’s
    group also assisted in the buyout by running the “Maggie” 14 forecasting model
    13 EBITDA is a company’s net income with its interest, taxes, depreciation, and
    amortization added back. See generally Gen. Elec. Capital Corp. v. Posey, 
    415 F.3d 391
    , 393
    (5th Cir. 2005).
    14 Maggie is a long-term financial projection model that Morgan Stanley used to assess
    Shaw’s intrinsic value.

    No. 18-31299
    for Morgan Stanley, which assessed Shaw’s worth for the acquisition. FP&A
    updated Maggie at least twice in May and June 2012, which was atypical;
    ordinarily Maggie was updated every six months. Liu’s coworker James
    McMahon (a member of the FP&A team) testified that based on these updates
    he believed Shaw was selling itself and assumed Liu, who had this same
    information, believed the same.
    The Government presented evidence that Liu had been told of the
    impending sale. CFO Ferraioli testified that he told Wallace about the planned
    sale of Shaw weeks before Shaw announced the deal, and coworker Meredith
    Guedry (a member of the FP&A team) in turn testified that Wallace told her
    team, including Liu, about CB&I’s pending acquisition of Shaw prior to the
    announcement. 15 Guedry’s detailed testimony about her conversations with
    Liu in June added credibility to her conclusion that she had “no doubt” Liu
    knew that the sale was pending. Indeed, Guedry explained that she and Liu
    discussed the acquisition at length. Fearing her job was at risk due to the
    acquisition, Guedry left Shaw’s Baton Rouge office in late June; Guedry
    testified that Liu knew why she was leaving and agreed with her decision.
    Liu relies on three district court cases to argue this evidence was
    insufficient to establish possession, yet they are all readily distinguishable.
    First, in S.E.C. v. Horn, the Northern District of Illinois held that while the
    defendant had potential access to information, that alone could not establish
    possession of material, nonpublic information. 16 Similarly, in S.E.C. v. Truong,
    the Northern District of California concluded that there was no evidence that
    the defendant had trading information, for he “was not made privy to
    15 The jury could have similarly relied on Wallace’s testimony that Liu relayed to the
    FP&A group talk she had heard from Shaw’s Environment and Infrastructure Division that
    “the deal is still on.”

    confidential sales and financial information in the normal course of his
    duties.” 17 Lastly, in S.E.C. v. Schvacho, the Northern District of Georgia, after
    conducting a bench trial, determined that a correlation between stock
    purchases and a few phone calls between two friends required too much
    conjecture. 18 In contrast to these cases, the evidence adduced at trial provided
    the jury with a sufficient basis to conclude that Liu actually possessed
    information about the impending sale of Shaw.
    b. Materiality
    Liu next argues that the evidence was insufficient to show that the
    information she possessed concerning the acquisition of Shaw was material.
    Liu underscores that any information she possessed was speculative and
    founded on rumor.
    Based on Supreme Court precedent, the district court charged the jury
    without objection that information is material “if a reasonable investor would
    consider it significant in the decision whether to invest, such that it alters the
    total mix of information available about the proposed investment.” 19 The court
    also clarified that “confirmation by an insider of facts or rumors that the
    company had not confirmed publicly itself may constitute material, nonpublic
    information.”
    As materiality “depends on the facts,” it “is to be determined on a case-
    by-case basis.” 20 While this court has not addressed this issue in the context of
    tipper liability, the Second Circuit has. In United States v. Mylett, for example,
    17 
    98 F. Supp. 2d 1086
    , 1089 (N.D. Cal. 2000).
    18 
    991 F. Supp. 2d 1284
    , 1299 (N.D. Ga. 2014).
    19 In TSC Indus., Inc. v. Northway, Inc., 
    426 U.S. 438
    , 449 (1976), the Supreme Court
    held that, in the proxy-solicitation context, an omitted fact was material if a reasonable
    investor would consider it “as having significantly altered the ‘total mix’ of information
    available.” Then, in Basic Inc. v. Levinson, 
    485 U.S. 224
    , 234 (1988), the Court expressly
    adopted that standard in the § 10(b) and Rule 10b-5 context.

    No. 18-31299
    the defendant, the Vice President of Labor Relations at AT&T, told his friend
    that a newspaper article speculating a merger between AT&T and an unnamed
    company was true, because he had conducted a feasibility study of the merger
    and had been told by his supervisor not to discuss the article. 21 On appeal, the
    court determined that a reasonable investor would find this information
    valuable, even if the merger was speculative. It held that a $6 billion
    acquisition could be considered “an event of great magnitude,” in part due to
    the “sharp jump” in the stock price after the announcement. 22 The court also
    found that there was a high probability of acquisition because the company
    had hired an investment bank, outside counsel, and accountants in
    preparation. 23 Similarly, in S.E.C. v. Mayhew, the Second Circuit held that a
    tip to the defendant that an acquisition was in the works was material. 24 The
    court concluded that because the information came from an insider and the
    merger discussions were “actual and serious,” a “lesser level of specificity” was
    necessary to constitute material information. 25
    On the other hand, the Fourth Circuit in Taylor v. First Union Corp. held
    that information being withheld concerning talks between banks did not
    constitute material information. 26 Two banks in separate states held a meeting
    to discuss the possibility of “developing a relationship.” 27 Following a Supreme

    Court decision declaring interstate banking to be constitutional, the two banks
    again met, this time to consider a merger. The Fourth Circuit determined that
    those discussions were “preliminary, contingent, and speculative.” 28 “At best,
    the merger discussions culminated in a vague ‘agreement’ to establish a
    relationship,” with “no agreement as to the price or structure of the deal.” 29
    This present case poses a stark contrast to Taylor. The information
    available to Liu in May 2012 when CB&I sent its 22-page due diligence request
    showed that the companies’ negotiations concerning a possible sale of Shaw
    were quite serious. As the summer progressed, Liu observed that Maggie had
    been updated out of cycle. She also participated on multiple calls with Morgan
    Stanley bankers who, referencing “the other side,” discussed the metric. Other
    members of FP&A eventually informed her that Shaw was being bought. Liu
    emphasizes that she did not know the price or other details of the deal, such
    as the buyer’s identity, but materiality in this instance does not demand that
    the tipper know all the details of the proposed transaction. Here, talks of an
    acquisition were far beyond speculation. That the information came from Liu,
    a deemed “insider,” made it all the more likely to affect the mix of total
    information available for the reasonable investor. Thus, the jury had sufficient
    evidence to conclude the information was material.
    c. Nonpublic
    Liu makes a conclusory claim that the information in question was
    public. Arguments not briefed are waived. 30 In any event, the information
    surrounding Shaw’s acquisition was clearly nonpublic. Information becomes
    public when it is disclosed “to achieve a broad dissemination to the investing

    United States v. Reagan, 
    596 F.3d 251
    , 254 (5th Cir. 2010) (holding a failure to
    fully brief constitutes a waiver).

    No. 18-31299
    public generally and without favoring any special person or group.” 31 Here, the
    evidence sufficiently showed that CB&I and Shaw kept the deal a secret until
    they announced the acquisition. Indeed, the companies went to great lengths
    to keep discussions confidential. Directors of both companies testified that they
    used code names, had access-controlled electronic data rooms, and executed
    confidentiality agreements.
    d. Disclosure
    Liu also argues that the Government failed to show that she disclosed
    this material, nonpublic information to Russo and Vic. She contends that
    communications between the parties, even if “timely,” were not so unusual as
    to reveal Liu disclosed any information about the buyout.
    The striking concert of action between Liu and her codefendants,
    however, presented a different tale to the jury. The phone records show that
    Liu, Vic, and Russo coordinated with one another at the precise times that Vic
    purchased Shaw call options and Russo’s mother purchased Shaw stock. The
    jury was entitled to find the timing of the communications revealing: Liu spoke
    with Russo numerous times, and she communicated with Diemo, who in turn
    spoke to Vic, repeatedly. 32 The highest volume of phone communications
    between Liu and Diemo in 2012 occurred in July, the most notable days being
    July 18, 19, and 30. Vic and Diemo also had the highest volume of phone
    communications between them in July 2012, similarly peaking on July 19
    (when Vic first ordered Shaw call options).
    31  Dirks v. S.E.C., 
    463 U.S. 646
    , 653 n.12 (1983) (citing In re Faberge, Inc., 45 S.E.C.
    249, 256 (1973)). The district court further instructed the jury that a “tip from a corporate
    insider that is more reliable or specific than public rumors is nonpublic information despite
    the existence of such rumors in the media or investment community.”
    32 For example, on July 26 (the day before the trades), Diemo and Liu exchanged 66
    calls and texts. Diemo and Vic exchanged 22 calls and texts.

    No. 18-31299
    Moreover, the Government produced more concrete evidence that these
    communications concerned Shaw’s pending acquisition. Russo’s mother
    testified to a grand jury that Liu admitted to her that she passed on the
    information about the pending Shaw buyout. 33 In addition to this direct
    testimony, the call records support an inference that Liu relayed her
    knowledge about the impending sale to Russo and Vic. On July 18, 2012, Liu
    and Russo exchanged a series of phone calls and texts. Immediately thereafter,
    Russo called his mother and asked permission to buy Shaw stock in her
    brokerage account, explaining he knew of rumors of an acquisition. Similarly,
    on July 19, 2012, Liu spoke with Diemo, who in turn spoke with Vic. Vic then
    contacted his brother, Chris Ho (“Chris”). Chris promptly called his brokerage
    firm on a recorded line to inquire into purchasing options for Shaw. During the
    call, he told the agent, “That’s all I needed to know, ‘cause you know how it is.
    Everybody always gets a tip. . . . [From] a friend of a friend and from a
    janitor.” 34 Finally, while Vic was communicating with his broker, a user logged
    onto Vic’s brokerage account from a device Liu regularly accessed and
    researched Shaw call options. The jury could infer Liu was the user who logged
    into the account to assist Vic in purchasing the call options. The evidence was
    33  Liu contends that this evidence could only be used for impeachment purposes. This
    is incorrect. Ms. Russo’s prior grand jury statement, while posing two layers of hearsay
    issues, is nonetheless admissible substantively. First, her statement as to what Liu told her
    is admissible under Rule 801(d)(2) of the Federal Rules of Evidence as an exclusion from
    hearsay, since Liu’s statement is a party admission. Second, Ms. Russo’s grand jury
    testimony satisfies the requirements of another exclusion from hearsay, Rule 801(d)(1)(A), as
    Ms. Russo testified under oath at a proceeding, and she is now subject to cross-examination
    about her earlier statement. Further, there is no Confrontation Clause issue; if Russo wanted
    to cross-examine his mother about why she made the prior statement, he had that
    opportunity.
    34 Vic’s friend Lance Burgos also testified that Vic called him that day to inform him
    of the acquisition rumors. Despite his familiarity with the stock market, Burgos stated Vic’s
    information came as a surprise to him.

    No. 18-31299
    thus sufficient for the jury to find that Liu passed on to Russo and Vic her
    knowledge about the pending acquisition of Shaw.
    e. Personal Benefit
    The Government had to demonstrate that Liu disclosed this
    aforementioned information for a personal purpose in breach of her fiduciary
    duty as a corporate insider. Liu does not contest that she was a corporate
    insider. Further, she concedes that, in regard to receiving a personal benefit,
    she “had a close personal relationship with Russo and Diemo Ho in July 2012”
    that “[a]s a matter of law . . . [is] sufficient to infer a personal benefit if [she]
    disclosed material nonpublic information for securities trading purposes.”
    f. Anticipation of Trade
    Liu asserts that even if she shared material, nonpublic information, she
    did not do so with any intention that Vic or Russo trade on it. Insider trading
    requires that a tipper’s “deceptive use of information be in connection with the
    purchase or sale of a security.” 35 Liu argues that, if anything, she told Russo
    not to trade Shaw stock.
    The jury had reason to conclude otherwise, for the reasons stated above.
    The jury was entitled to find that, because Liu was researching Shaw call
    options from Vic’s account apparently to assist in purchasing the options, she
    understood precisely what Vic was in the process of doing: purchasing Shaw
    call options based on the information she furnished him about Shaw’s potential
    acquisition. Additionally, on July 27, 2012, the date that Vic purchased his
    Shaw call options and nine days after the flurry of communication began, Vic
    asked his broker if he could sell his options on July 30, the date that CB&I
    announced its purchase of Shaw. A reasonable juror could find that Liu

    , 655–56 (1997).

    No. 18-31299
    conveyed the approximate date of the acquisition to Vic, so he could purchase
    and sell Shaw options on the most advantageous dates.
    g. Unlawful Trade
    The Government had to show that Vic and Russo actually traded (i.e.,
    bought or sold) Shaw securities. The Government provided sufficient evidence
    that Vic and Russo did so. The jury saw records from Vic’s optionsXpress
    account and Russo’s mother’s brokerage account at Edward Jones (in which he
    had a beneficial interest) that showed both parties, acting on the information
    Liu provided, purchased Shaw stock or options.
    h. Scienter
    Liu contends that the evidence was insufficient to prove she acted with
    the requisite scienter to commit securities fraud. That is, Liu argues that she
    did not act knowingly, willfully, and with the intent to defraud. 36 The district
    court defined “knowing” for the jury as requiring Liu acted voluntarily and
    intentionally, not because of mistake or accident. It defined “willfully” to mean
    that Liu acted purposely with the specific intent to either disobey or disregard
    the law. Lastly, it defined “specific intent to defraud” as to act with an intent
    to deprive Shaw of the confidentiality of its material, nonpublic information.
    The Government provided the jury with sufficient evidence that Liu
    knew the trading scheme was unlawful and nevertheless participated. As a
    member of FP&A, Liu received training on insider trading and handling
    confidential corporate information. 37 She also knew that, as an “insider,” she
    could not trade during blackout periods, and Shaw sent quarterly emails
    reminding her of this policy. The policy explicitly stated she could not “pass on
    36See 
    Dirks, 463 U.S. at 664
    n.23 (1983).
    37The Shaw Group Code of Corporate Conduct explicitly defined material information
    as information “that is important to a reasonable investor in deciding whether to buy or sell
    a company’s stock or other securities.” It also listed acquisitions as an example of material,
    nonpublic information.
    14

    No. 18-31299
    to others” any material, nonpublic information. She would have understood
    that any information concerning a potential merger was confidential, yet she
    shared it anyway. In addition, the Government produced evidence that Liu lied
    to the FBI and IRS in 2014, claiming that she did not know about the merger
    prior to the announcement, despite having been emailed that the acquisition
    cleared the day before. A jury was entitled to find that Liu acted with the
    requisite scienter.
    i. Interstate Commerce
    To be convicted of insider trading, Liu had to have used some
    instrumentality of interstate commerce. The instrumentality could be a
    telephone, the internet, mail, or the facilities of a national securities exchange.
    Liu does not contest that the scheme involved an instrumentality of interstate
    commerce.
    B. Conspiracy
    Liu argues that the evidence was insufficient to prove a conspiracy to
    commit securities fraud. For the Government to prove a conspiracy under 18
    U.S.C. § 371, it had to show “(1) an agreement between two or more persons to
    pursue an unlawful objective; (2) the defendant’s knowledge of the unlawful
    objective and voluntary agreement to join the conspiracy; and (3) an overt act
    by one or more of the members of the conspiracy in furtherance of the objective
    of the conspiracy.” 38 “An agreement may be inferred from concert of action,
    voluntary participation may be inferred from a collection of circumstances, and
    knowledge may be inferred from surrounding circumstances.” 39 A conspiracy
    “may be established by either direct or circumstantial evidence.” 40 Liu argues

    609 F.3d 699
    , 704 (5th Cir. 2010).
    39  United States v. Grant, 
    683 F.3d 639
    , 643 (5th Cir. 2012) (internal citations and
    quotation marks omitted).

    879 F.2d 1260
    , 1265 (5th Cir. 1989).

    Case: 18-31299       Document: 00515182773        Page: 16     Date Filed: 10/31/2019
    No. 18-31299
    the Government failed to demonstrate she intentionally entered into an
    agreement to commit insider trading, as the communications between parties
    would have happened regardless of any conspiracy.
    As the above elements of insider trading illustrate, however, the
    Government offered sufficient evidence to demonstrate Liu provided inside
    information to Russo and Vic and voluntarily agreed to join them in
    committing insider trading. The back-and-forth communications and
    subsequent trades, meanwhile, constitute overt acts in furtherance of the
    conspiracy. Therefore, Liu’s challenge to her conspiracy conviction fails.
    C. Severance
    Liu contends that this court should vacate her conviction and remand for
    a new trial because the district court abused its discretion in failing to grant a
    severance and try her separate from Vic and Russo. Rule 14 of the Federal
    Rules of Criminal Procedure allows severance as justice requires. Prejudice
    alone, however, does not mandate severance; rather, Rule 14 “leaves the
    tailoring of the relief to be granted, if any, to the district court’s sound
    discretion.” 41 A severance should be granted “only if there is a serious risk that
    a joint trial would compromise a specific trial right of one of the defendants, or
    prevent the jury from making a reliable judgment about guilt or innocence.” 42
    “There is a preference in the federal system for joint trials of defendants who
    are indicted together.” 43
    This court reviews a district court’s failure to sever a defendant from a
    trial by the “exceedingly deferential” abuse of discretion standard. 44 The
    appellant must show that “(1) the joint trial prejudiced him to such an extent

    No. 18-31299
    that the district court could not provide adequate protection; and (2) the
    prejudice outweighed the government’s interest in economy of judicial
    administration.” 45 In conspiracy cases, this court “generally favor[s] specific
    instructions over severance.” 46 “A spillover effect, by itself, is an insufficient
    predicate for a motion to sever.” 47
    Liu argues that the district court erred in not granting a severance for
    two reasons. First, she contends that the evidence regarding Vic’s tax fraud,
    including his remark that he was “in trouble” to his tax preparer, would have
    been inadmissible against her because it was irrelevant; she also argues that
    jury instructions failed to cure prejudice. Second, Liu argues that Chris’s
    statement that he received a tip would have been inadmissible against her,
    because Chris was neither an alleged coconspirator nor a tippee.
    Most of the evidence against Vic that Liu complains is prejudicial would
    have been admissible against her in a separate trial. Even if isolated items of
    evidence were not admissible against Liu, the district court’s instructions
    provided her with adequate protection. Specifically, the district court
    instructed the jury that “sometimes an exhibit may be admissible only as to
    one defendant and not the others,” and Vic’s tax fraud was “such [an] exhibit[]
    and may be considered only insofar as defendant Victory Ho is concerned, but
    should not be considered as to defendants Kelly Liu and Salvador Russo.” Liu
    fails to show the prejudice required for a severance, and her challenge to the
    district court’s denial of her motion to sever is thus without merit.

    For these reasons, we AFFIRM the district court’s judgment.
