The FBI has been investigating whether payments that originated in a bank account held by Aruze USA that were made in 2010 to Rodolfo Soriano, an associate of the then-head of the Philippine gaming regulator, constituted a violation of U.S. anti-bribery laws, according to people with knowledge of the probe. At the time of the payments, Universal was seeking tax and other concessions related to a casino it is building on Manila Bay.
