This is an appeal from a conviction following a jury trial on two counts of conspiracy to defraud the United States in violation of 18 U.S.C. § 371. Section 371 makes it a crime for two or more persons to conspire either to commit any offense against the United States, or to defraud the United States. Appellants here have been convicted of conspiring to defraud the United States by structuring certain currency transactions totalling several hundred thousand dollars to thwart the ability of the United States to obtain information concerning currency transactions for more than $10,000 under 31 U.S.C. § 5323(a).
I. STATEMENT OF THE CASE
In pertinent part, Section 5313(a) of Title 31 U.S.C. provides that:
When a domestic financial institution is involved in a transaction for the payment, receipt, or transfer of United States coins or currency ... in an amount, denomination, or amount and denomination, or under circumstances the Secretary prescribes by regulation, the institution ... shall file a report on the transaction at the time and in the way the Secretary prescribes.
The relevant part of 5312(a)(2) of Title 31 U.S.C. provides:
In this subchapter ...
(2) “Financial institution” means (A) an insured bank (as defined in Section 3(h) of the Federal Deposit Insurance Act, 12 U.S.C. 1813(h)).
Appellants were indicted for having conspired to defraud the United States on two *1551counts, one dealing with certain transactions made by appellants on October 28, 1983 and October 81, 1983, during which two days they together purchased for currency cashier’s checks totalling $88,740, and on the second count for having on June 11 and June 27, 1984, engaged in similar transactions, this time purchasing for currency $179,122 worth of money orders from 32 banks or savings and loan institutions or branches thereof. In both types of purchases, they used some fictitious names.
There was ample proof that during several of these purchases on a single day, the two appellants, from the same cache of currency, bought either two cashier’s checks for more than $10,000 at different branches of the same bank or bought money orders for more than $10,000 from different branches of the same bank. There was ample evidence of the fact that they did this for the purpose of preventing any “financial institution” from having to file a Currency Transaction Report (“CTR”). Such a report is required under regulations issued by the Secretary of the Treasury under the authorization of Section 5313:
Each financial institution shall file a report of each deposit, withdrawal, exchange of currency or other payment or transfer, by, through, or to such financial institution, which involves a transaction in currency of more than $10,000.
31 C.F.R. § 103.22(a).1
There is no question that appellants did engage in a single transaction, although disguised as more than one, on the same day at branches of the same bank during the period covered by each count of the indictment.
II. ISSUE
We consider the only issue to be decided is whether structuring the transactions in amounts of less than $10,000 in different branches of the same bank for the purpose of avoiding the currency reporting requirements of 31 U.S.C. § 5313 constitutes a conspiracy to defraud the United States, in violation of 18 U.S.C. § 371.
III. DISCUSSION
The appellants contend that there is no obligation on any financial institution to file a CTR unless a currency transaction for more than $10,000 in a single day is carried on at a single branch of a bank or savings institution. They base this argument on the definition section of the regulation at 31 C.F.R. § 103.11. There, a “financial institution” is defined as:
Each agency, branch, or office within the United States of any person doing business in one or more of the capacities listed below:
(1) A bank (except bank credit card systems);
(2) A broker or dealer in securities;
(3) A person who engages as a business in dealing in or exchanging currency as, for example, a dealer in foreign exchange or a person engaged primarily in the cashing of checks;
(4) A person who engages as a business in the issuing, selling, or redeeming of travelers’ checks, money orders, or similar instruments, except one who does so as a selling agent exclusively or as an incidental part of another business;
(5) A licensed transmitter of funds, or other person engaged in the business of transmitting funds abroad for others;
(6) (i) A casino or gambling casino licensed as a casino or gambling by a State or local government and having gross annual gaming revenue in excess of $1,000,000;
(ii) A casino or gambling casino includes the principal headquarters and *1552any branch or places of business of the casino or gambling casino.
Appellants’ argument is that since each branch of a bank is defined in the regulation as being a “financial institution,” the transaction which is dealt with in the statute and regulation must be a transaction solely within a particular branch or office.
The government challenges this argument on two bases. The first is its argument that if a person has in his possession a substantial sum of currency in excess of $10,000 and, in order to prevent a bank or one of its branches from having to file a CTR with respect to his turning the currency into paper, he divides it up into several different packages and over a period of time, makes an exchange of currency for a cashier’s check or a money order in any number of financial institutions, he is guilty, because he attempted to thwart the financial institution from having to file a CTR which he ought not to have done because he ought to have incorporated all of his transactions into one transaction in a single bank. The second basis for the government’s argument is that where a person on the same day makes an exchange out of one fund of cash in two branches of the same bank for cashier’s checks or money orders, this is a single transaction with a single financial institution and the two exchanges should be considered together to require “the bank” to file a CTR covering the transaction.
The government’s first argument is overbroad. As we have already found in United States v. Denemark, 779 F.2d 1559 (1986), the mere fact that an individual has a substantial amount of cash in his possession which he wishes to turn into cashier’s checks or other evidence of indebtedness and does so at different banks over a period of days, cannot amount to a crime because his actions amounted to several transactions instead of a single transaction as is contemplated under the statute.
However, we have here facts which distinguish this case from Denemark, because here, there were several single transactions on the same day, with the same bank, albeit with different branches of the bank. We agree with the government’s contention that such exchanges made by a single person'or his partners or associates in a single day, in different branches of the same bank, do require the bank to file a CTR. This is true, because the statute, under which the regulation is issued, requires the filing of a CTR by a “financial institution” which is defined in the statute as, among other things, “a bank.” (31 U.S.C. § 5312(a)(2)). As stated by the district court in United States v. Sanchez Vazquez, 585 F.Supp. 990 (N.D.Ga.1984):
While the regulations do govern when a CTR must be filed, the court disagrees with defendant’s interpretation of the term “financial institution.” The court believes that the statute, 31 U.S.C. 5312, and the regulations 31 C.F.R. 103.11, must be read together in determining the meaning of the term “financial institution.”
The court determines that the correct interpretation of the implementing regulations in defining the term “financial institution” is a bank, including each of its branches. Thus, if the financial institution (i.e., the bank or in particular any of its branches) is aware of its cash transaction in excess of $10,000 on a particular day, the bank or its particular branch must file a CTR. Likewise, if there are multiple cash transactions at different branches of the same financial institution (i.e., bank) which exceed $10,-000, then that particular bank must file a CTR....
Since we do not construe a regulation in a manner that would place it in conflict with the statute by which it is authorized, we construe the regulation here as did the court in Sanchez Vazquez.
The facts here are much akin to those in United States v. Tobon-Builes, 706 F.2d 1092 (11th Cir.1983) and United *1553 States v. Thompson, 603 F.2d 1200 (5th Cir.1979). In those two cases, a bank was caused to consider as separate transactions, exchanges by or on behalf of a single person at the same time, in the same institution. The only difference here is that the exchanges occurred in different branches of the same bank. We conclude that under the statute and the implementing regulation it was incumbent upon the bank to file a CTR with respect to these transactions which occurred on the same day, and the actions of the appellants in structuring the exchanges by making them in different branches of the same institution and by the use of false names was sufficient to constitute the crime for which they were charged.
We have also considered appellant’s argument that the statutory regulatory requirements that banks report currency transactions in excess of $10,000 violates the bank customer’s Fourth and Fifth Amendment rights and that the trial court erred in its instruction to the jury as to the existence of mens rea. We find no error with respect to the trial court’s rejection of these contentions.
The judgments are AFFIRMED.
