Structuring
Structuring, also called smurfing is a way to cheat in American banking.  It is the act of breaking a large sum of money into smaller sums to hide it from the law.  Some United States laws, for example the Bank Secrecy Act and Internal Revenue Code say people have to tell the government if they move large amounts of money all at once.  By moving the money in smaller amounts, people can sneak past the law.  People might structure if they are trying to make criminal money look like honest money or committing fraud.
