In July 2017, a United States appeals court threw out the convictions of two men charged with Libor manipulation, because key evidence was derived from testimony that had been compelled in the United Kingdom, in violation of their rights under the US Constitution, with potentially broad implications for furture cross-border investigations. The Court of Appeals for the Second Circuit in New York ruled in US v Allen that the Fifth Amendment priviledge against self-incrimination extends to testimony compelled by other soverign governments. This article exmines the Allen ruling and its likely implications.
The SEC has recently signaled a renewed focus on the investigation and prosecution of accounting fraud with the creation of a Financial Reporting and Audit Task Force. The Task Force will use sophisticated computer algorithms to mine financial filings looking for potential irregularities. The SEC is expected to take a close look at companies particularly in the technology sector, and at revenue recognition. The article examines recent public statements and SEC enforcement actions that help provide clues to the SEC’s renewed focus in this area.
South Korea’s equivalent to the FCPA is the Foreign Bribery Prevention Act or FBPA for short. Although passed more than 15 years ago, it was rarely used—until now. Recent activity under the act is an encouraging sign that Korea may be stepping up its enforcement activity.
Recent court decisions concerning the interplay of the FCPA and personal jurisdiction over foreign nationals provide guidance for corporate counsel on FCPA risks. The bottomline—adopt, maintain, and continually update robust compliance and training programs throughout the organization, set the proper tone at management levels throughout the company, and, as appropriate, insist that third party intermediaries with whom the company works follow those same policies.
The long arm of U.S. law can be seen clearly in recent enforcement of the Foreign Corrupt Practices Act or FCPA, a criminal law prohibiting bribery of non-U.S. government officials. Companies whose operations even remotely touch the U.S. and who therefore could come within the FCPA’s jurisdiction should consider implementing anti-corruption compliance programs to prevent, detect, and remediate violations. Such programs can be a key mitigating factor in U.S. regulators’ decisions whether to bring an enforcement action or in the penalties sought if an action is brought.
Last year saw a sharp increase in investigations targeting the illicit flows of funds through financial institutions. In three prominent enforcement actions in 2012—against ING, Standard Chartered Bank and HSBC—prosecutors and regulators extracted massive fines for conduct ranging from intentional concealment of illicit transactions to ineffective monitoring.
The Guide addresses several key issues arising from the FCPA on which multinationals have long sought guidance, including (i) the elements of an effective anti-corruption compliance program; (ii) gifts and entertainment expenses; (iii) facilitating payments; (iv) the FCPA's broad definition of "foreign official"; (v) successor liability when a company merges with or acquires another company that has committed acts of bribery; and (vi) FCPA jurisdiction over foreign companies that do not trade on U.S. exchanges.
