Armco, a U.S. manufacturer of armor for automobiles, participates in a trade show in a foreign country. It operates a booth at which it gives away pens, teeshirts, and other promotional items displaying the Armco logo; it also serves free beverages and snacks. Given the nature of its product, many of the visitors to the booth are foreign officials, and Armco knows this fact. In itself, does this conduct violate the FCPA? What if as the day is ending, a foreign official approaches the Armco representative, explains that he has lost his wallet, and requests the equivalent of $100 for cab fare to the airport? What if, instead, the Armco representative takes a group of foreign officials out to an expensive restaurant for dinner at a cost of $100 per person? Do any of these behaviors violate the FCPA?
