    OPINION
    MURNAGHAN, Circuit Judge:
    Mija Romer and Khem Batra (Appellants), were tried by a jury for
    various offenses stemming from their involvement in a conspiracy to
    rig bids at real estate foreclosure auctions. Both Appellants were con-
    victed of violating the Sherman Act, 15 U.S.C. § 1. In addition,
    Romer was convicted of bank fraud, in violation of 18 U.S.C. § 1344,
    and tax fraud in violation of 18 U.S.C. § 371. On appeal, Appellants
    make various assignments of error with respect to their convictions,
    and Romer challenges her sentence. Finding no error, we affirm.
    I.
    Appellants are real estate speculators who, together with others,
    participated in a conspiracy to limit bidding competition at certain
    public foreclosure auctions in Fairfax County, Virginia. The purpose
    of the conspiracy was to hold down the price of auctioned properties
    by agreeing not to bid against one another at auctions -- an activity
    commonly known as "bid-rigging." During an auction, most members
    of the conspiracy would refrain from bidding, while one designated
    member would bid on and receive the property at a much-reduced
    2
    price. Following the auction, members of the conspiracy would hold
    a private auction amongst themselves, at which point they would dis-
    cuss the price they each would have bid for the property. The person
    with the highest bid would be given the deed, and the conspirators
    would divide amongst themselves the money saved by artificially
    holding down the price of the property.
    Under Virginia law, all sales of foreclosed properties must be con-
    ducted at public auctions. See Va. Code Ann.§ 55-59(7). If the lender
    who initiates the foreclosure is an out-of-state entity, a Virginia resi-
    dent must be appointed to serve as "trustee." See Va. Code Ann. § 55-
    58.1(2). The trustee has a fiduciary duty to obtain the highest possible
    purchase price for the property. Following the auction, the trustee
    remits all proceeds to the appropriate parties -- the lender receives
    sufficient funds to pay off the mortgage and the remainder is returned
    to the homeowner or used to satisfy remaining liens.
    As a result of their bid-rigging activities, Appellants were indicted
    by a federal grand jury on September 12, 1996. The indictment
    charged both Appellants, inter alia, with violating the Sherman Act,
    15 U.S.C. § 1, by conspiring to rig bids on nine properties sold at pub-
    lic auction. Appellants were also indicted for conspiracy to evade the
    payment of federal taxes, in violation of 18 U.S.C.§ 371. Romer was
    individually indicted for bank fraud, in violation of 18 U.S.C. § 1344,
    for obtaining a loan by submission of false earnings information.
    The case proceeded to a jury trial on January 21, 1997, in the
    United States District Court for the Eastern District of Virginia. At
    trial, Romer testified that she had attended and bid at private auctions
    on ten properties, and Batra admitted his involvement with six. The
    Government introduced evidence suggesting that members of the con-
    spiracy had been concerned about having their illegal earnings
    detected and that they had agreed to make auction payments in cash
    in order to evade the Internal Revenue Service (IRS). Co-conspirator
    Leo Gulley testified that, following one private auction in March of
    1994, members of the conspiracy, including both Appellants, had dis-
    cussed the danger of creating a "paper trail" by making payments to
    each other with checks. Those present agreed that all payments would
    be made in cash. Gulley's testimony was confirmed by that of co-
    conspirator Alexander Giap, who had become a government infor-
    3
    mant and surreptitiously tape-recorded a number of the conspiracy's
    meetings. During one taped conversation, Romer cautioned the others
    that "you can't report it on your taxes." She later emphasized that "we
    don't want any check writing between us. If we get caught by IRS,
    we'll be dead."
    The Government also produced evidence regarding Romer's fraud-
    ulent effort to obtain a loan from Herbert Bank and Trust Co. in Octo-
    ber 1993. The evidence showed that in order to obtain approval for
    the loan, Romer, who is a CPA, informed bank officials that her gross
    income for 1992 was approximately $90,000. The bank approved
    Romer's loan based on her oral statement, but requested that Romer
    submit a tax return to substantiate her income. In response to that
    request, Romer submitted a bogus IRS Form 1040, which she claimed
    to be her 1992 tax return and which overstated her gross income by
    approximately $85,000.
    Appellants were convicted of violating the Sherman Act, and
    Romer was convicted of bank fraud and conspiracy to defraud the
    IRS. In determining Romer's sentence, the district court began with
    a base-offense level of 10, pursuant to U.S.S.G.§ 2R1.1(a). The court
    then granted a 1-level enhancement, as authorized by U.S.S.G.
    § 2R1.1(b)(1), for submitting non-competitive bids in an antitrust
    conspiracy. The court also granted a 2-level enhancement for obstruc-
    tion of justice, under U.S.S.G. § 3C1.1, based on the court's finding
    that Romer had intentionally withheld material information during
    sentencing. After grouping Romer's antitrust and tax conspiracy
    offenses, pursuant to U.S.S.G. § 3D1.2(c), and combining the result,
    as required by U.S.S.G. § 3D1.4, with Romer's bank fraud convic-
    tion, the court arrived at an offense level of 14. The court then sen-
    tenced Romer, within the applicable range, to a term of 18 months
    imprisonment on each count, followed by a total of 3 years supervised
    release, and ordered Romer to pay $27,269 in fines and restitution.
    This appeal followed.
    II.
    Appellants contend that the district court erred in denying their
    motion for judgment of acquittal, pursuant to Fed. R. Crim. P. 29(c),
    since the Government failed to demonstrate that the conspiracy's bid-
    4
    rigging activities involved "commerce among the several states," as
    required by § 1 of the Sherman Act. We review de novo the district
    court's decision to deny judgment of acquittal. See United States v.
    United Med. & Surgical Supply Corp., 
    989 F.2d 1390
    , 1401-02 (4th
    Cir. 1993) (citing United States v. Garcia, 
    868 F.2d 114
    , 115 (4th Cir.
    1989)). Where, as here, a motion for judgment of acquittal is based
    on insufficiency of the evidence, the conviction must be sustained if
    the evidence, when viewed in the light most favorable to the Govern-
    ment, is sufficient for any rational trier of fact to find the essential ele-
    ments of the crime beyond a reasonable doubt. See Jackson v.
    Virginia, 
    443 U.S. 307
    , 319 (1979) (citation omitted). In reviewing
    the sufficiency of the evidence, we are not entitled to weigh the evi-
    dence or to assess the credibility of witnesses,"but must assume that
    the jury resolved all contradictions . . . in favor of the Government."
    United 
    Medical, 989 F.2d at 1402
    (citation omitted). With these stan-
    dards in mind, we now consider the merits of Romer's argument.
    Section 1 of the Sherman Act provides in pertinent part that
    "[e]very contract, combination in the form of trust or otherwise, or
    conspiracy, in restraint of trade or commerce among the several
    States, . . . is hereby declared to be illegal." 15 U.S.C. § 1. The lan-
    guage of the Sherman Act is conspicuous for its breadth. See United
    States v. South-Eastern Underwriters Ass'n, 
    322 U.S. 533
    , 553 (1944)
    ("Language more comprehensive [than that used in § 1 of the Sher-
    man Act] is difficult to conceive."). Indeed, the Supreme Court has
    noted that by using the phrase "commerce among the several States,"
    Congress intended the Sherman Act to reach the constitutional limits
    of the commerce power. See Summit Health, Ltd. v. Pinhas, 
    500 U.S. 322
    , 329 n.10 (1991) ("Congress ``meant to deal comprehensively and
    effectively with the evils resulting from contracts, combinations and
    conspiracies in restraint of trade, and to that end to exercise all the
    power it possessed.'") (quoting Atlantic Cleaners & Dyers, Inc. v.
    United States, 
    286 U.S. 427
    , 435 (1932)).
    In a Sherman Act prosecution, the government bears the burden of
    proving beyond a reasonable doubt a connection between the defen-
    dant's activities and interstate commerce.1 See McLain v. Real Estate
    _________________________________________________________________
    1 The government's success in demonstrating the required nexus with
    interstate commerce "is both a critical jurisdictional fact and an element
    of the substantive offense charged under 15 U.S.C.§ 1. Facts sufficient
    for the one are sufficient for the other, and vice versa." United States v.
    Foley, 
    598 F.2d 1323
    , 1328 n.2 (4th Cir. 1979).
    5
    Bd. of New Orleans, Inc., 
    444 U.S. 232
    , 242 (1980). In McLain, the
    Supreme Court explained that in order to meet its burden the govern-
    ment must "demonstrate by submission of evidence beyond the plead-
    ings either [1] that the defendants' activity is itself in interstate
    commerce or, [2] if it is local in nature, that it has an effect on some
    other appreciable activity demonstrably in interstate 
    commerce." 444 U.S. at 242
    (citation omitted). The first of these standards allows for
    application of the Sherman Act where the defendant's allegedly anti-
    competitive activities "lie directly in the flow of interstate com-
    merce." United States v. Foley, 
    598 F.2d 1323
    , 1328 (4th Cir. 1979).
    Under the second standard, a defendant's conduct, although "wholly
    local in nature," 
    McLain, 444 U.S. at 241
    , falls within the ambit of
    the Sherman Act when, "as a matter of practical economics," the
    activities "have a not insubstantial effect on the interstate commerce
    involved," 
    id. at 246
    (quoting Hospital Bldg. Co. v. Rex Hospital
    Trustees, 
    425 U.S. 738
    , 745 (1976)).
    Although the McLain standards are often described as "tests," we
    explained in Foley that "[o]bviously these are not bright line, mutu-
    ally exclusive tests," and that it may be "quite possible to analyze a
    particular pattern of activities without express reliance upon 
    either." 598 F.2d at 1328
    ; see, e.g., Goldfarb v. Virginia State Bar, 
    421 U.S. 773
    (1975). Therefore, although our analysis may be guided by the
    McLain standards, we are mindful that our goal is to answer the
    "more general question, whether the activities under alleged restraint
    have a sufficient nexus with interstate commerce." 
    Foley, 598 F.2d at 1329
    .
    In the present case, Appellants argue that the Government has
    failed to carry its burden of establishing that their seemingly local
    bid-rigging activities had the required nexus with interstate com-
    merce. In support of that contention, Appellants point out that the
    auctions involved Virginia real property; took place entirely within
    the Commonwealth of Virginia; and that the participants, including
    the trustee and all non-institutional bidders, were Virginia residents.
    In light of those facts, Appellants contend that the thrust of the con-
    spiracy's activities was purely local.
    We disagree. As an initial matter, we note that the narrow concep-
    tion of interstate commerce reflected in the Appellants' argument is
    6
    without support in the law. Determining whether anti-competitive
    activities are within the reach of the Sherman Act is a practical
    inquiry, one which requires us to consider the substance of the trans-
    action at issue. In conducting that inquiry, we look beneath the sur-
    face of the transaction, with an eye toward assessing its interstate
    features. We consider not only the location of the transaction and the
    immediate parties, but all other conceivable links with interstate com-
    merce, including the interests of secondary parties and the passage
    across state lines of goods and services related to the transaction.
    In light of the broad nature of our inquiry, we disagree with the
    Appellants' characterization of their auction-rigging activities as
    purely local. The driving force behind each auction was the financial
    interest of an out-of-state lender, who initiated the auction to recover
    the balance of an outstanding debt. Although each sale of property
    was conducted through the conduit of a Virginia trustee, that relation-
    ship was one of form rather than substance. In reality, the trustee was
    a mere resident agent, appointed by the lender to conduct the auction
    on the lender's terms. Despite superficial appearances, it was the
    lender who initiated the foreclosure, who directed the terms of the
    auction, and who, at the close of each sale, received across state lines
    some portion of the proceeds in satisfaction of its interest in the prop-
    erty. Therefore, we find it inescapable that, far from being purely
    local events, the auctions were interstate transactions of the most fun-
    damental sort.
    Appellants' next contention is that, even assuming the auctions
    were interstate in nature, the Government has failed to demonstrate,
    under 
    Goldfarb, 421 U.S. at 784
    , that the Appellants' participation
    was "integral" to or "inseparable" from the auctions. Appellants argue
    that the presence of non-institutional bidders, like themselves, was not
    necessary to the conduct of the auctions because, even in the absence
    of non-institutional bidders, the lender's own representative could bid
    on and receive the property at a price sufficient to cover the outstand-
    ing debt.
    We find that argument unpersuasive. While it is no doubt true that
    the auctions could have proceeded in the absence of non-institutional
    bidders, Appellants were not convicted of rigging bids at hypothetical
    auctions they did not attend. Their convictions were for collusive
    7
    behavior at nine auctions which they not only attended, but at which
    they were the successful bidders. By purchasing property at foreclo-
    sure auctions initiated by out-of-state lenders, Appellants assumed a
    role that was not only integral to but inseparable from the interstate
    sale of property. We therefore have no difficulty concluding that their
    activities were in the flow of interstate commerce.
    In a final attempt to escape liability under the Sherman Act, Appel-
    lants argue, in reliance on United States v. Lopez, 
    514 U.S. 549
    (1995), that the Sherman Act exceeds Congress's power to regulate
    pursuant to the Commerce Clause, because it grants federal jurisdic-
    tion over local activities with only a de minimis or attenuated connec-
    tion to interstate commerce. However, under the express language of
    Lopez, an act of Congress is a valid exercise of the commerce power
    where, as here, the act contains a "jurisdictional element which . . .
    ensure[s], through case-by-case inquiry, that the [activity] in question
    affects interstate commerce." 
    Id. at 561.
    Because we have conducted
    such an inquiry in the case at bar, we are confident that we have satis-
    fied our obligations under Lopez.
    In summary, we hold that when viewed in the light most favorable
    to the Government the evidence is sufficient to convince a jury
    beyond a reasonable doubt that the Appellants' bid-rigging activities
    had the requisite nexus with interstate commerce. We therefore affirm
    the district court's denial of judgment of acquittal.
    III.
    Appellants maintain that the district court erroneously stated appli-
    cable law when it gave a supplemental jury instruction regarding the
    meaning of interstate commerce. The instruction included a hypothet-
    ical example in which three Virginia Volvo dealers conspired to fix
    the prices they charged for automobiles received from Volvo of
    America. The court explained that this type of agreement, "although
    formed in state, is going to have an impact on interstate commerce . . .
    [b]ecause part of the goods that are involved here are shipped from
    out of state . . . ." Hence, the court explained,"one of the things you
    have to look at in this case is the extent to which you find that there
    are out-of-state aspects of the real estate foreclosure process."
    According to Appellants, the court's instruction was erroneous
    8
    because the use of the automobile analogy improperly compared real
    property to movable goods, and the instruction focused the jury's
    attention on the out-of-state aspects of the real estate foreclosure pro-
    cess.
    We review the district court's jury instructions"in their entirety
    and in context." United States v. Muse, 
    83 F.3d 672
    , 677 (4th Cir.
    1996) (citing Cupp v. Naughten, 
    414 U.S. 141
    , 146-47 (1973)).
    Therefore, we consider the language of the supplemental instruction
    together with all other instructions given by the district court on the
    interstate commerce issue. In the present case, Appellants failed to
    object to the district court's supplemental instruction during trial. Pur-
    suant to Fed. R. Crim. P. 52(b), we are entitled to notice an error not
    preserved by timely objection only if the defendant can demonstrate
    that (1) an error occurred, (2) which was plain, and (3) which affected
    his or her substantial rights. See also United States v. Olano, 
    507 U.S. 725
    , 731-32 (1993). Even where such an error is identified, the deci-
    sion to correct the error remains within the sound discretion of the
    court of appeals, to be exercised only when the error "seriously af-
    fect[s] the fairness, integrity or public reputation of judicial proceed-
    ings." 
    Id. at 732
    (quoting United States v. Young, 
    470 U.S. 1
    , 15
    (1985)).
    Upon a thorough review of the record, we cannot say that the dis-
    trict court's instructions were erroneous, let alone plainly erroneous.
    Contrary to Appellants' contentions, we find the court's choice of an
    automobile analogy to be appropriate. Although a piece of real estate
    being sold in interstate commerce does not itself pass across state
    lines, title certificates, advertising, financing, and other goods and ser-
    vices generated by the transaction pass from state to state as readily
    as automobiles. And the district court was careful to inform the jury
    that the focus of their inquiry was not the out-of-state activities them-
    selves, but the relationship or impact of the Appellants' conduct to
    those activities. We therefore find no error in the district court's
    instructions.
    IV.
    Appellants challenge the district court's refusal to grant two jury
    instructions pertaining to the defense's theory of the case. The first
    9
    was a Black's Law Dictionary definition of the term"joint venture."
    According to Appellants, that instruction was necessary "because it
    defined a joint venture differently from a partnership insofar as it is
    a ``one time group of two or more persons in a business undertaking.'"
    The second requested instruction was to inform the jury that bid-
    rigging is only illegal if it is "an agreement between competitors not
    to bid."
    It is well-settled that a district court should grant a jury instruction
    requested by the defense so long as the instruction has evidentiary
    foundation and accurately states applicable law. See United States v.
    Stotts, 
    113 F.3d 493
    , 496 (4th Cir. 1997) (citations omitted). Ordinar-
    ily, we review the district court's refusal to grant a proposed instruc-
    tion for an abuse of discretion, see United States v. Russell, 
    971 F.2d 1098
    , 1107 (4th Cir. 1992), but in the present case, although Appel-
    lants requested that the proposed instructions be given, they failed to
    object to the district court's denial of those requests. Therefore, under
    
    Olano, 507 U.S. at 731-32
    , our review of the district court's rulings
    is limited to plain error. See United States v. Arthurs, 
    73 F.3d 444
    ,
    448 (1st Cir. 1996) (applying plain error analysis where defendant
    requested instruction but failed to object when denied); United States
    v. Tringali, 
    71 F.3d 1375
    , 1380 (7th Cir. 1995) (same), cert. denied
    sub nom. Hernandez v. United States, 
    117 S. Ct. 87
    (1996).
    In the instant case, we are not convinced that the district court's
    rejection of the proposed instructions was plain error. As the court
    obviously recognized, the first instruction threatened to confuse the
    jury's understanding of applicable law. Given that danger, the court's
    own instruction -- that "forming a partnership or an agreement to bid
    on a contract [is not] necessarily a violation of the [Sherman A]ct" --
    was adequate to inform the jury of the point the defendants sought to
    make.
    As to the second instruction, it is true that bid-rigging is typically
    defined as an agreement "between competitors" to submit or withhold
    contract offers from a third party. See United States v. Portsmouth
    Paving Corp., 
    694 F.2d 312
    , 325 n.18 (4th Cir. 1982) ("[C]ollusive
    bidding is ``an agreement between competitors in a bidding contest to
    submit identical bids or, by preselecting the lowest bidder, to abstain
    from all bona fide effort to obtain the contract.'") (quoting 1 R. Call-
    10
    mann, The Law of Unfair Competition, Trademarks and Monopolies
    203 (4th ed. 1981)); United States v. Sargent Elec. Co., 
    785 F.2d 1123
    , 1127 (3rd Cir. 1986) ("An agreement among persons who are
    not actual or potential competitors in a relevant market is for Sherman
    Act purposes [an act without consequence]."). Here, the district
    court's instructions, standing alone, informed the jury only that the
    "critical factor" in a bid-rigging conspiracy is "an agreement between
    two or more persons to either eliminate, reduce or interfere with com-
    petition." While we believe that instruction may have been erroneous,
    we have no occasion to decide the issue in the case at bar, since even
    assuming, arguendo, that plain error occurred, it cannot be said that
    the error affected the Appellants' substantial rights.
    We have recently held that to establish the third prong of the Olano
    plain error analysis in cases of jury misinstruction, the defendant
    bears the burden of proving that "the error actually affected the out-
    come of the proceedings," United States v. Hastings, 
    134 F.3d 235
    ,
    240 (4th Cir. 1998) (citations omitted), in other words, "that the jury
    actually convicted him based upon an erroneous understanding of the
    [law]," 
    id. at 243
    (citation omitted).
    In the instant case, Appellants cannot meet their burden of demon-
    strating actual prejudice, since there was no evidence on which a
    properly instructed jury could have concluded that Appellants and
    their cohorts were anything but competitors. According to Appellants'
    own testimony, members of the conspiracy agreed to hold down the
    price of auctioned property by not bidding against one another. There
    was no evidence whatsoever that the purpose of that collusion was,
    as Appellants have suggested, merely a "partnership" to pool
    resources, share research, or spread risks. Quite the contrary, all the
    evidence suggested that the purpose of the conspiracy was to obtain
    property at artificially depressed prices and to divide the savings
    among those competitors who refrained from bidding. In light of all
    this, we find no reason to believe that a properly instructed jury could
    have acquitted the Appellants, and we affirm their convictions accord-
    ingly.
    V.
    Appellants maintain that the district court erred in admitting two
    pieces of evidence during trial. We review the district court's rulings
    11
    for an abuse of discretion. See United States v. Ellis, 
    951 F.2d 580
    ,
    582 (4th Cir. 1991); United States v. Masters , 
    622 F.2d 83
    , 87-88 (4th
    Cir. 1980) (citations omitted). For the reasons stated below, we
    affirm.
    A. Newspaper Article
    The first piece of contested evidence is a Washington Post newspa-
    per article that described a recent bid-rigging conviction in the Dis-
    trict of Columbia. The Government introduced the article to provide
    background to a taped conversation that occurred on October 1, 1994,
    in which the conspirators referred to the article and its discussion of
    convictions. According to Appellants, the article was inadmissible
    hearsay under Rules 801 and 802 of the Federal Rules of Evidence,
    and, in any event, was more prejudicial than probative and should
    have been excluded under Rule 403.
    With respect to the first contention -- that the article was inadmis-
    sible hearsay -- the district court held that the article was admissible
    because it was not offered to prove the truth of its contents, see Fed.
    R. Evid. 801(c), but rather to place in its proper context the conspira-
    tors' taped discussion about the article. The district court cautioned
    the jury that the article was not offered "to prove the guilt or inno-
    cence of any of the defendants in this court or to establish that there
    was, in fact, a conspiracy in th[e] District[of Columbia]. It simply
    was introduced in the area of the reactions to the article and certain
    comments that may have been made about it." In light of the indepen-
    dent relevance of the article and the district court's careful instruction
    to the jury regarding the limits of its use, we are confident that the
    article was admissible.
    We also reject Appellants' contention that the article was imper-
    missibly inflammatory under Rule 403, which provides that otherwise
    relevant evidence "may be excluded if its probative value is substan-
    tially outweighed by the danger of unfair prejudice, confusion of the
    issues, or misleading the jury . . . ." In the present case, although the
    article may have had some prejudicial impact, we cannot say that such
    impact substantially outweighed the article's probative value. More-
    over, any danger of prejudice was substantially minimized by the dis-
    trict court's careful instructions to the jury that the article was being
    12
    offered for context only and that the conduct described therein
    occurred in a different jurisdiction and "may or may not be similar to
    the conduct involved here." Therefore, we cannot say that the district
    court abused its discretion by admitting the article into evidence.
    B. Plea Agreement
    The next piece of challenged evidence is the testimony of co-
    conspirator Alexander Giap regarding a plea agreement he reached
    with the Government. When called by the Government to testify at
    trial, Giap explained that, as a result of his involvement with the con-
    spiracy, he had pled guilty to three felonies, including bid-rigging,
    which he described as participating in an "agreement not to compete
    at . . . public auctions." Such was the full extent of evidence heard by
    the jury regarding Giap's plea agreement. The agreement itself was
    neither read to the jury nor submitted into evidence.
    Although it is generally recognized that the prosecution can intro-
    duce evidence of a plea agreement during direct examination of a
    government witness, that freedom is not unlimited. See United States
    v. Henderson, 
    717 F.2d 135
    , 137 (4th Cir. 1983). Whenever the gov-
    ernment offers evidence of a plea agreement, there is a danger that
    "the agreement may aid the government by indicating the witness's
    knowledge of the crime or by [conveying] . . . the unspoken message
    . . . ``that the prosecutor knows what the truth is and is assuring its rev-
    elation.'" 
    Id. (quoting United
    States v. Roberts, 
    618 F.2d 530
    , 536
    (9th Cir. 1980)). To guard against such danger, we have held that the
    government may elicit testimony regarding a plea agreement only if:
    (1) the prosecutor's questions do not imply that the government has
    special knowledge of the witness's veracity; (2) the trial judge
    instructs the jury on the caution required in evaluating the witness's
    testimony; and (3) the prosecutor's closing argument contains no
    improper use of the witness's promise of truthful cooperation. See 
    id. at 138.
    In the present case, the district court fully complied with the safe-
    guards laid out in Henderson. At no point during questioning or clos-
    ing argument did the Government imply special knowledge or
    guarantee of Giap's veracity, and the district court gave a cautionary
    instruction that, due to Giap's status as an informant, his testimony
    13
    must be viewed more critically than that of other witnesses. There-
    fore, we cannot say that the district court abused its discretion by
    admitting the challenged testimony.
    VI.
    Romer contends that the Government's evidence and arguments at
    trial constituted a variance from her indictment. According to Romer,
    although her indictment alleged bank fraud by way of submission of
    false documents, the Government's evidence at trial suggested that
    she also facilitated fraud by way of oral statements to bank officials.
    We have previously explained that a variance occurs when "the
    evidence at trial establishes facts materially different from those
    alleged in the indictment." United States v. Kennedy, 
    32 F.3d 876
    ,
    883 (4th Cir. 1994) (citations omitted). Where a variance is found to
    have occurred, reversal is required only if the defendant demonstrates
    that the error infringed his or her "substantial rights" and thereby
    resulted in "actual prejudice." 
    Id. at 883
    (citations omitted). In United
    States v. Fletcher, 
    74 F.3d 49
    (4th Cir.), cert. denied, 
    117 S. Ct. 157
    (1996), we explained that prejudice may result if the variance sur-
    prises the defendant at trial and thereby hinders his or her ability to
    prepare a defense, or if the variance exposes the defendant to the risk
    of a second prosecution for the same offense, see 
    id. at 53
    (citations
    omitted).
    In the case at bar, we are not persuaded that a variance was com-
    mitted. Although Romer's indictment does not mention oral state-
    ments, the language of the indictment is broad and non-exclusive. It
    alleges that Romer "executed a scheme . . . to defraud a financial
    institution . . . by means of false and fraudulent pretenses, representa-
    tions and promises," and that, "[a]s part of the loan application pro-
    cess," Romer submitted a false IRS Form 1040. Although the
    indictment mentions Romer's false IRS form, it does not exclude
    other statements or submissions that were part and parcel of the same
    fraudulent endeavor.
    In any event, even assuming, arguendo, that a variance occurred,
    Romer has failed to demonstrate actual prejudice. Under 18 U.S.C.
    § 1344, bank fraud consists of "knowingly execut[ing], or attempt[-
    14
    ing] to execute, a scheme or artifice . . . (2) to obtain [funds] . . . by
    means of false or fraudulent pretenses, representations, or promises
    . . . ." Here, even disregarding all evidence of false statements,
    Romer's conviction could be sustained on the basis of her fraudulent
    tax form alone. In any event, we are confident that any variance, if
    indeed one occurred, did not subject Romer to the threat of a second
    prosecution or hinder her ability to prepare a defense. Therefore, even
    assuming that the Government's evidence varied from the indictment,
    no prejudice resulted and we affirm Romer's conviction accordingly.
    VII.
    Romer claims that the district court erred in denying her motion for
    judgment of acquittal, pursuant to Fed. R. Crim. P. 29(c), since the
    evidence was insufficient to support her conviction for defrauding the
    IRS. As discussed previously, we review the district court's ruling on
    a motion for judgment of acquittal de novo, see United 
    Medical, 989 F.2d at 1401-02
    , asking whether the evidence, when viewed in the
    light most favorable to the Government, is sufficient to sustain a find-
    ing of guilt beyond a reasonable doubt as to each essential element
    of the offense, see 
    Jackson, 443 U.S. at 319
    .
    Romer was convicted of conspiracy to evade the payment of fed-
    eral taxes, in violation of 18 U.S.C. § 371. To prove a violation of
    § 371 -- often referred to as a Klein conspiracy, see United States v.
    Klein, 
    139 F. Supp. 135
    (S.D.N.Y. 1955) -- the government must
    establish: (1) that an agreement existed; (2) that the conspirators com-
    mitted an overt act in furtherance of the conspiracy; and (3) that the
    defendant intended to agree to the conspiracy and to defraud the
    United States. See United States v. Tedder, 
    801 F.2d 1437
    , 1446 (4th
    Cir. 1986) (citation omitted). In the present case, Romer contends that
    the Government failed to meet its burden as to the first and third ele-
    ments of its case.
    We disagree. With respect to the first element, the Government
    presented sufficient evidence, by way of tape-recorded conversations,
    to establish that members of the conspiracy reached an agreement to
    make private auction payments in cash. At one meeting, Rosen asked
    Romer, Batra, Giap, and Gulley, "If I'm the successful bidder . . . [d]o
    I put [it] on my income tax? . . . [I]s this money being reported or
    15
    not?" Gulley responded by stating, "[S]o what we're saying [is] we
    go cash . . . ." Romer answered, "Right," and Rosen, Giap, and Gulley
    agreed. Rosen then emphasized that the parties "can't report [the ille-
    gal earnings] on [their] taxes." During a later conversation, Romer
    reaffirmed to the others the importance of using cash, stating: "Every-
    thing that we do from now on has gotta be cash. . . . Because we don't
    want any check writing between us. If we get caught by the IRS, we'll
    be dead." In light of this evidence, we have no difficulty concluding
    that Romer entered into an agreement to refrain from reporting her
    illegal earnings to the IRS.
    As to the third element, Romer contends that the Government's
    evidence was insufficient to prove a specific intent to defraud the IRS
    of tax revenues, as opposed to an intent merely to avoid detection for
    bid-rigging. We find that argument to be unpersuasive. Although it is
    well-settled that a Klein conspiracy exists only when an objective of
    the agreement is "to thwart the IRS's efforts to determine and collect
    income taxes," United States v. Vogt, 
    910 F.2d 1184
    , 1202 (4th Cir.
    1990) (citations omitted), the evidence here is sufficient to support a
    determination that such a purpose existed. We are confident that a
    jury, when faced with the tape-recorded conversations -- including,
    most notably, Romer's statement that "if the IRS catches us, we'll be
    dead" -- could reasonably have concluded that Romer was at least in
    part motivated by the desire to evade the payment of federal taxes.
    We therefore affirm Romer's conviction for tax fraud.
    VIII.
    Romer's appeal alleges five assignments of error with respect to
    her sentence. We have carefully considered each of those contentions,
    and we find that only two necessitate extended discussion. In review-
    ing the remaining contentions, we are required by statute to give "due
    regard to the opportunity of the district court to judge the credibility
    of the witnesses," and must "accept the findings of fact of the district
    court unless they are clearly erroneous." 18 U.S.C. § 3742(e) (1988).
    Questions regarding the legal interpretation of the guidelines are
    reviewed de novo. See United States v. Daughtrey , 
    874 F.2d 213
    , 217
    (4th Cir. 1989). With these standards in mind, we address each of
    Romer's arguments in turn.
    16
    A. "Non-Competitive Bids"
    Romer contends that the district court erred in granting an upward
    enhancement in her sentence, pursuant to U.S.S.G.§ 2R1.1(b)(1).
    That provision authorizes a one-level upward enhancement "[i]f the
    conduct involved participation in an agreement to submit non-
    competitive bids . . . ." According to Romer, that enhancement was
    intended to apply only to "bid-rotation" cases and was, therefore,
    improperly applied in the case at bar.
    In support of her argument, Romer relies exclusively on the Sev-
    enth Circuit's decision in United States v. Heffernan, 
    43 F.3d 1144
    (7th Cir. 1994). In that case, the defendant was a steel drum manufac-
    turer who had conspired with other manufacturers to sell drums to
    customers at identical prices. See 
    id. at 1145.
    The district court
    granted a one-level enhancement in the defendant's sentence, pursu-
    ant to § 2R1.1(b)(1), on the grounds that the conspiracy's activities
    constituted bid-rigging. On appeal to the Seventh Circuit, the court
    reversed, holding that price-fixing by way of submission of identical
    bids was not the sort of behavior to which § 2R1.1(b)(1) was intended
    to apply. See generally 
    id. at 1146-50.
    In reaching that conclusion, the
    court determined, among other things, that § 2R1.1(b)(1) applied only
    to bid-rotation cases, and that the price-fixing engaged in by the con-
    spiracy did not qualify as bid-rotation. Romer asks us to reach the
    same conclusions in the case at bar.
    We decline to do so. For starters, we are not persuaded that
    § 2R1.1(b)(1) is limited to bid-rotation cases.2 The language of the
    guideline is broad and non-exclusive. It authorizes a one-level
    enhancement for all cases involving the submission of "non-
    competitive bids." If the Sentencing Commission intended the
    enhancement to apply only to bid-rotation cases, it is reasonable to
    believe that the general term "non-competitive bids" would have been
    replaced by a more particular term, like "bid-rotation" or "comple-
    _________________________________________________________________
    2 In Heffernan, the court explained that bid-rotation, which is also
    sometimes referred to as the submission of "complementary bids," occurs
    when a group of bidders agree "for each job . . . which of them shall be
    the low bidder, and the others submit higher bids to make sure the desig-
    nated bidder 
    wins." 43 F.3d at 1146
    .
    17
    mentary bids." That conclusion is strengthened by the fact that
    § 2R1.1(d)(3) actually uses the term "complementary bids," and dis-
    cusses such conduct as though it were a sub-category, rather than a
    synonym, of bid-rigging in general. The lack of similar specificity in
    § 2R1.1(b)(1) would appear to indicate that the Commission intended
    the enhancement to apply generally to all forms of bid-rigging.
    In any event, even if we assume, arguendo, that § 2R1.1(b)(1)
    applies only to bid-rotation cases, we are not convinced that auction-
    rigging is excluded from that category. It was undisputed that, prior
    to each auction, members of the conspiracy discussed which of them
    would submit the lowest bid, and the others agreed to abstain from
    bidding or, at the very least, not to outbid the chosen bidder. Bidding
    of that nature is complementary in the sense that the bids submitted
    and withheld are designed to assist the chosen bidder in obtaining the
    property at the lowest possible price, with the understanding that, over
    time, each conspirator will receive an appropriate pay-off. That is
    very different from the conduct faced in Heffernan, where the manu-
    facturers merely agreed to sell their drums for an identical price and
    no complementary bids were exchanged. Therefore, even assuming
    that § 2R1.1(b)(1) applies only to bid-rotation, we are confident that
    auction-rigging falls within that category. We therefore conclude that
    the district court was justified in granting an upward enhancement.
    B. Obstruction of Justice
    Romer's final argument is that the district court erred in granting
    an enhancement in her sentence for obstruction of justice, pursuant to
    U.S.S.G. § 3C1.1. The court granted the enhancement on the grounds
    that Romer had failed to provide the probation office with a complete
    accounting of her assets, which included various lines of credit
    amounting to over $36,000; the proceeds of seven properties Romer
    sold during 1996, which totaled more than $400,000; and the pro-
    ceeds from the sale of a time-share property in Florida, which totaled
    more than $4,500.
    Section 3C1.1 authorizes a two-level upward enhancement "[i]f the
    defendant willfully obstructed or attempted to obstruct or impede, the
    administration of justice during the investigation, prosecution, or sen-
    tencing of the instant offense . . . ." The commentary to § 3C1.1 pro-
    18
    vides a non-exhaustive list of conduct which constitutes obstruction
    of justice, including "providing materially false information to a pro-
    bation officer in respect to a presentence . . . investigation for the
    court." U.S.S.G. § 3C1.1, comment. n.3(h). Under the Guidelines,
    material evidence is that which, "if believed, would tend to influence
    or affect the issue under determination." U.S.S.G. § 3C1.1, comment.
    n.5.
    In the case at bar, Romer maintains that the district court erred in
    failing to make an explicit finding of materiality with respect to the
    information withheld from the probation officer. We are unpersuaded.
    Although it is true that the district court did not make an express find-
    ing of materiality, our cases have never held that such a finding is
    required. Instead, it is sufficient if a finding of materiality may be
    implied from the court's statements during sentencing. See United
    States v. Saintil, 
    910 F.2d 1231
    , 1233 (4th Cir. 1990). Here, the dis-
    trict court imposed an upward enhancement after providing Romer
    with the opportunity to explain her failure to be forthcoming with
    regards to her assets. In response to Romer's explanation that this fail-
    ure was a mere oversight, the district judge stated,"I have problems
    with somebody who's a CPA being that lax in remembering the
    details, especially in a context that's as important as a presentence
    investigation . . . . [I am unable] to accept your statement that you
    merely forgot to fully disclose all of your assets." We believe a find-
    ing of materiality is implicit in the court's remarks. The court's state-
    ments and the context in which they were given reveal that the matter
    was given careful consideration and that the court believed that
    Romer had intentionally withheld information material to the presen-
    tence investigation.3 The upward enhancement is therefore affirmed.
    _________________________________________________________________
    3 Furthermore, because an accurate estimate of a defendant's assets is
    a prerequisite to the imposition of fines, see U.S.S.G. § 2R1.1, comment.
    n.2, we cannot say that the district court's finding of materiality was
    clearly erroneous. See United States v. Hicks , 
    948 F.2d 877
    , 886 (4th Cir.
    1991) ("The question of materiality [under§ 3C1.1] is a factual determi-
    nation . . . subject to the clearly erroneous standard of review.") (citation
    omitted).

    In summary, we affirm the district court on all matters.
