2.73.1 Money Laundering Concealing Illegal Proceeds / 18 U.S.C. Sec. 1956(a)(1)(B)(i) is a federal law that criminalizes the act of concealing criminal proceeds. It is a form of money laundering, which is defined as the process of disguising the origins of illegally obtained money by making it appear to have come from a legitimate source. This law applies to individuals and organizations who knowingly engage in a financial transaction with the proceeds of certain specified unlawful activities, such as drug trafficking, racketeering, terrorism, and other serious crimes. There are three different types of money laundering activities identified in this law: 1) Transaction laundering, which involves disguising the source of the funds through a series of financial transactions; 2) Structuring, which involves breaking up large deposits into smaller amounts to avoid detection; and 3) Layering, which involves transferring the funds between different accounts and entities to disguise the source of the funds. Under this law, individuals and organizations can face criminal penalties, including fines and imprisonment, for violating these provisions.
