Former CEO Wong Weng Sun and ex-manager Lee Fook Kang face five charges of conspiring to offer incentives to a middleman to aid Sembcorp Marine’s Brazilian subsidiaries, according to the city state’s statement.

The total sum involved in the offences between 2009 and 2014 amounted to about US$44 million, the attorney general’s chambers and Singapore’s Corrupt Practices Investigation Bureau added in the statement.

In an emailed statement, Wong said, “I have always acted in the best interests of the companies, and would never compromise them by engaging in corrupt activities,” during 35 years working in Sembcorp Marine and one of its units.

“The charges relate to the companies’ Brazilian operations, and I intend to demonstrate my innocence,” he added in the statement his lawyers, Wong Partnership, sent to Reuters.

Lawyers for Lee said they were not in a position to comment, as they had just been engaged on the matter.

Wong has also been charged with obstruction of justice after he allegedly told two Sembcorp employees in 2014 to delete an email sent by the middleman that contained evidence of bribes.

Singapore prosecutors were in talks with Seatrium for a deferred prosecution agreement to pay a penalty of US$110 million, the statement added.

Seatrium told the stock exchange on Thursday that the attorney general’s chambers was agreeable to entering into the deferred prosecution agreement.

It said it was committed to the highest standards of compliance, including zero tolerance of bribery and corruption.
