Sydney, Aug 16: BHP Billiton said on Friday US authorities have laid out grounds for possible enforcement action against the top global miner for corrupt practices, stepping up a four-year probe linked partly to its 2008 Olympics sponsorship.

The company has been under investigation by the Securitiesand Exchange Commission (SEC) and the Department of Justice (DOJ) since 2009, mainly over exploration activities that had been terminated and its hospitality at the Beijing Olympic Games.

“As a part of the US process, the SEC and DOJ have recently notified the group of the issues they consider could form the basis of enforcement actions and discussions are continuing,” BHP said in a statement, adding that it could not comment on possible outcomes.

BHP has said previously it believed it had complied with all applicable laws in regards to its Olympics sponsorship, and said on Friday it has what it considers to be a “world class anti-corruption compliance program.”

“BHP Billiton is fully committed to operating with integrity and the group's policies specifically prohibit engaging in unethical conduct,” the company said, adding that it was cooperating fully with the authorities.

After being approached by the SEC, the company said in 2010 that it had uncovered potential violations of anti-corruption laws “involving interactions with government officials”, which media have said related to a payment to Cambodian officials in 2006 for a bauxite project that BHP later dropped.—Reuters
