Jonathan S Abernethy, S Gale Dick, and Christian R Everdell authored an article titled “The Department of Justice’s new ‘piling on’ policy” for the International Bar Association’s October 2018 Criminal Law and Business Crime Newsletter.

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.

Examining how FCPA whistleblowers have been incentivized and the impacts this rewards structure may have on ‘business as usual’.

 

Examining the Dodd-Frank and US Foreign Corrupt Practices Acts  and ways in which companies can institute and augment compliance programs to mitigate the risks they pose.

The implications of the Galleon ruling in terms of white collar defense - specifically the growing use of wiretapping during insider trading investigations.

Jonathan S Abernethy spoke on a panel about defending individuals in corporate internal investigations and related prosecutions at this year’s IBA Annual Conference in Seoul.

Mark S Cohen and Muriel Goldberg-Darmon served as guest lecturers at the Université Paris I – Panthéon Sorbonne for the 2017 fall semester. They taught a course titled “U.S. White Collar Criminal Law” to students in the Master 2 (JD equivalent) program. The course covered the fundamental principles of U.S. criminal law and a review of the key participants in white collar criminal practice. The course also covered substantive white collar issues, such as FCPA, banking, and finance-related issues. Jonathan S Abernethy and Christian R Everdell served as visiting lecturers. Reggie B Schafer served as the course’s teaching assistant.

The webinar features Jon Abernethy (Partner, Cohen & Gresser) and Andrew Curtin (Global Head of Investigations, AIG) for a special webcast focusing on managing legal and cultural risks in cross-border investigations. It covers:

  • Handling multi-jurisdictional approaches to priviledged communications in the aftermath of the recent U.K. decision in Eurasian Natural Resources Corporation Ltd. and The RBS Rights Issue Litigation
  • Identifying potential cultural challenges and local laws that may impede an effective investigation and prevent a one-size-fits-all approach to designing internal processes and procedures within multinational organizations
  • Implementing best practices when preparing for and coordinating effective internal investigations across international lines

Jon participated in a panel at the IBA’s 20th Annual Transnational Crime Conference in Lisbon, Portugal.  The panel, entitled “The Right to Silence When Everyone Else Is Talking,” examined the right against self-incrimination from the perspective of several countries in a world of increased cross-border information sharing between investigators, regulators, and prosecuting authorities.

Experiential legal learning platform AltaClaro has partnered with international law firm Cohen & Gresser, LLP to host a live online panel to discuss current trends in anti-money laundering enforcement.

Jon participated in this panel at Deloitte’s 10th Annual U.S. Anti-Money Laundering (AML) Conference at Fordham Law School in New York.

C&G partner Jonathan S Abernethy will speak at the 2014 Annual Conference of the International Association of Korean Lawyers (IAKL) at Fordham Law School in New York City.  Mr. Abernethy will be a panelist on the Conference’s Anti-Corruption Panel, and will address, among other subjects, recent trends in FCPA enforcement and how companies can mitigate risks through effective compliance programs and procedures.

Drawing prominent members of the white–collar bar, this panel addresses current issues relating to government investigations and compliance, public integrity, and the Foreign Corrupt Practices Act
