Last week, a subsidiary of American fashion designer Ralph Lauren Corporation made global news for violations of The Foreign Corrupt Practices Act of 1977 ("FCPA"). In short, FCPA prohibits covered entities – i.e., those that reside in the United States or entities that are considered "issuers" under the securities laws of the United States – from paying anything of value to a foreign government official to obtain or retain a business advantage or for the purpose of directing business to any person.
