> The Foreign Corrupt Practices Act of 1977 is a United States federal law that prohibits U.S. citizens and entities from bribing foreign government officials to benefit their business interests.
> Regarding payments to foreign officials, the act draws a distinction between bribery and facilitation or "grease payments", which may be permissible under the FCPA, but may still violate local laws. The primary distinction is that grease payments or facilitation payments are made to an official to expedite his performance of the routine duties he is already bound to perform
