OPINION
Neil Roger Beidler appeals his conviction and sentence for structuring currency transactions in violation of 31 U.S.C. § 5324(3) (1988), arguing primarily that the evidence is insufficient to support a conclusion that he willfully violated that provision. We conclude that the evidence establishes that Bei-dler engaged in extensive efforts to conceal his structuring activity and that the evidence of those efforts is sufficient to support an inference that he was aware of the illegality of his conduct. Accordingly, we affirm.
I.

Federal law requires that domestic financial institutions file a currency transaction report (CTR) for a transaction or series of transactions involving currency in an amount greater than $10,000.
See
31 U.S.C. § 5313(a) (1988); 31 C.F.R. § 103.22(a)(1) (1991). Furthermore, it is unlawful to struc

ture, to assist in structuring, or to attempt to structure or to assist in structuring a currency transaction for the purpose of avoiding the reporting requirement.
See
31 U.S.C. § 5324(3). In 1991, however, when the events relevant to this litigation transpired, an individual could not be convicted of violating the antistructuring law absent proof that he did so “willfully.” 31 U.S.C. § 5322(a), (b) (1988) (providing for the imposition of penalties upon “[a] person willfully violating” the antistructuring laws). And, in
Ratzlaf v. United States,
B.
Viewed in the light most favorable to the Government, the evidence demonstrated the following. Beidler is a real estate agent whose firm possessed the exclusive right to market townhouses being constructed for the Wellington Forest retirement community located in Amherst, Virginia. In the fall of 1991, the builder of the development, John Batman, requested assistance from Beidler in procuring financing for the project. Bei-dler obtained the names of several potential investors, including Wendell Wood, from a business associate. Beidler was introduced to Wood by a mutual acquaintance.
Beidler ultimately obtained Wood’s agreement to supply $100,000 in financing for the Wellington Forest project. However, Wood wished to protect his anonymity by concealing his identity as the source of funding for the development. Accordingly, Wood provided Beidler with cash in increments of up to “$20,000 or $30,000” at a time. 2 J.A. 351. Beidler deposited the funds into his own accounts and then drew checks on those accounts payable to Batman.
It is the manner in which Beidler deposited the funds from Wood that resulted in his indictment for structuring currency transactions. Rather than depositing each cash payment from Wood in a lump sum, Beidler made a total of 34 deposits to four different accounts at three different banks. Moreover, Beidler travelled to numerous branch locations to make the deposits. For example, between 9:00 a.m. and 2:00 p.m. on December 18, 1991, Beidler made the following deposits: Two deposits of $4,000 each at the Madison Heights branch of Central Fidelity Bank (each deposit was taken by a different teller; the record does not reveal the temporal proximity of the deposits); $4,000 at the Downtown branch of Central Fidelity Bank; $4,000 at the Amherst branch of Central Fidelity Bank; $4,000 at the Amherst branch of First Virginia Bank; $4,000 at the Downtown branch of First Virginia Bank; $4,000 at the Madison Heights branch of First Virginia Bank; and $5,000 at the Timberlake branch of First Virginia Bank. In short, Beidler deposited a total of $33,000 in eight deposits at seven different branches of two banks over the course of a five-hour period. Although the December 18 transactions were the most egregious in a consistent pattern, also noteworthy are Beidler’s deposits total-ling $18,500 at five branches of three banks on October 10 and 11, 1991 and his deposits totalling $18,000 at four different branches of a single bank over the course of two business days, October 18 and 21,1991.
*1067 Beidler subsequently was convicted of one count of structuring currency transactions. 3 He was sentenced to 15 months imprisonment and ordered to pay a $5,000 fine.
II.
Beidler’s primary contention on appeal is that the evidence is insufficient to support his conviction. A defendant challenging the sufficiency of the evidence to support his conviction bears “a heavy burden.”
United States v. Hoyte,
At trial, Beidler candidly acknowledged that he received currency from Wood in amounts greater than $10,000 and that he divided the cash into smaller sums for deposit because he wished to avoid the filing of a, CTR. Nevertheless, Beidler maintained that he was unaware that structuring transactions to evade the filing of a CTR was unlawful, instead asserting that he broke up the deposits of money from Wood in order to avoid small-town gossip. Before us, Beidler argues that the evidence concerning his acts of structuring does not support a conclusion that he knew it was unlawful to structure a currency transaction for the purpose of evading the reporting requirement. 4
*1068 A.
Before turning to the merits of Bei-dler’s sufficiency argument, we first must consider a legal issue that we have not previously decided: Whether evidence that a defendant attempted to conceal the structuring of currency transactions may, with or without other evidence, support a conclusion that the defendant knew structuring was unlawful. For the reasons set forth below, we hold that it may.
We begin with the proposition that evidence that a defendant structured currency transactions, without more, is not sufficient to prove that the defendant knew his conduct was illegal.
See United States v. Ismail,
After
Ratzlaf,
the circuit courts of appeals have struggled with the quantum of proof beyond mere structuring that is sufficient to establish knowledge of illegality. There is general agreement that special knowledge conferred by a defendant’s professional status is evidence that the defendant knew of the illegality of structuring a currency transaction.
See United States v. Simon,
The circuit courts of appeals are divided, however, with respect to the question of whether a defendant’s attempts to conceal the structuring of transactions may suffice to prove knowledge of illegality.
See Ismail,
While it certainly would make sense for a person cognizant of the reporting requirement but unaware of the illegality of structuring to make two separate purchases at two separate banks — e.g., a purchase of $5,000 and a purchase of $6,460 — in order to obtain $11,460 without triggering a report to the IRS, the faet that defendant instructed his wife to make three separate purchases at three separate banks suggests that defendant had a purpose beyond evasion of the reporting requirement: concealment of his structuring. And proof of concealment tends to prove knowledge of illegality.
Id.
Similarly, the Second Circuit has held that “when the method of structuring suggests a significant effort not only to avoid the bank reporting requirements but to
conceal
the currency structuring
itself
from authorities,
Ratzlaf’s
requirement of [proof that the defendant knew structuring was illegal] is satisfied.”
Simon,
We think: that the majority rule is the better one. Willfulness is rarely proven by direct evidence; rather, the factfinder must “ ‘draw[ ] reasonable inferences from the available facts.’ ”
Marder,
*1070 B.
We now turn to the question of whether the evidence presented in this case is sufficient to support Beidler’s conviction. The Government presented no evidence that Beidler possessed a particular familiarity with currency reporting requirements as a result of his status as a real estate agent.
See Simon,
Although Beidler admitted that he received large sums of cash from Wood, he never deposited more than $5,000 at any one time, and most often made deposits of $4,000 or less. Moreover, Beidler made the deposits at different branches of multiple banks, often travelling to several different branches in the same day. All in all, the Government’s evidence showed that during the period when Wood was providing financing for the Wellington Forest project, Beidler made 34 cash deposits, totalling $116,500,
6
at 10 different branches of three different banks. If Bei-dler’s only intent was to avoid the filing of a CTR, 12 separate deposits would have served his purpose just as well. Based upon the fact that Beidler made more deposits than the minimum necessary to evade the reporting requirements, the jury reasonably could have inferred that Beidler intended to conceal his structuring because he knew structuring was illegal.
See Simon,
III.
We hold that evidence concerning a defendant’s attempt to conceal the structuring of currency transactions may suffice to prove that the defendant knew his conduct was illegal. Here, the evidence presented by the Government of Beidler’s efforts to conceal his structuring of currency transactions was sufficient to justify a determination beyond a reasonable doubt that Beidler knew his activities were unlawful. Accordingly, we affirm. 7
AFFIRMED.
Notes
. Congress has since amended § 5322 to omit the willfulness requirement with respect to violations of § 5324. See 31 U.S.C. § 5322(a), (b) (1994).
. Additionally, the deed of trust on the properties that Wood received in exchange for the funds identified him only as “holder.” The parties agree that this practice, while uncommon, is not illegal.
. Beidler was also charged with conspiracy to commit offenses against the United States, see 18 U.S.C.A. § 371 (West 1966); money laundering, see 18 U.S.C.A. § 1956(a)(1)(B) (West Supp. 1996); and engaging in monetary transactions in property derived from specified unlawful activity, see 18 U.S.C.A. § 1957 (West Supp.1996). The jury acquitted him of these charges.
. Beidler also maintains that the district court erred in refusing to give his proposed instruction on willfulness. We will find error in the refusal of the district court to give a proffered instruction only if the instruction was correct, was not otherwise covered by the charge to the jury, and dealt with a point so important to the trial “that failure to give the requested instruction seriously impaired the defendant's ability to conduct his defense."
United States v. Lewis,
In order to prove the defendant guilty of [structuring currency transactions] the Government must prove the following essential elements beyond a reasonable doubt. First, the defendant willfully structured or attempted to structure a currency transaction with a financial institution and, second, the defendant structured or attempted to structure the currency transaction for the specific purpose of evading the currency transaction reporting requirements of the law.
... [Y]ou are instructed that the Government must prove that the defendant acted willfully. Willfully means to act with knowledge that one[']s conduct is unlawful and with intent to do something the law forbids, that is to say, with bad purpose to disobey or disregard the law.
The defendant’s conduct was not willful if it was due to negligence, inadvertence, mistake or the result of good faith and misunderstanding of the requirements of the law. In this connection it is up to you to decide whether the defendant acted in good faith, that is, whether he sincerely misunderstood the requirements of the law or whether he knew what he was required to do and deliberately] did not do so.
J.A. 435-36. We conclude that the district court adequately instructed the jury that in order to conclude that Beidler "willfully” violated the an-tistructuring laws, it had to find that Beidler acted .with knowledge that his conduct was illegal.
See United States v. Griffin,
.
Ismail
does not require a contrary holding. There, the evidence established that the defendants began structuring their transactions only after they were advised of the currency reporting requirements by a bank employee.
See Ismail,
. The parties agree that the amount of financing supplied by Wood was $100,000. The record does not contain an explanation of the discrepancy between the Government’s evidence of the deposits made by Beidler and the evidence regarding the amount of funds received from Wood.
. Having carefully considered Beidler’s remaining allegations of error, we conclude that they are without merit.
