Investigations, Enforcement and Business Crime
Government regulators and criminal prosecutors around the world continue to increase their focus on the activities of banks and corporations, wherever located, along with their senior officers, directors, and outside advisors.
Successfully managing the risks arising from this increased focus requires a deep understanding of both the technical legal requirements of multiple jurisdictions and the practical concerns and investigative methods used by government regulators and criminal prosecutors.
A&O’s market-leading global investigations, enforcement and business crime practice advises clients on a wide range of high-profile criminal and regulatory investigations, particularly cross-border matters.
Our global team comprises lawyers with extensive experience of working together in multiple jurisdictions and includes former prosecutors in the U.S. and Europe. We provide a ‘one stop shop’ to clients dealing with multiple regulators and other international government bodies, reducing the complexity involved in managing complex investigations and enforcement issues.
We advise on the full range of business crime issues, ranging from internal and regulatory investigations to high profile disputes. As well as having extensive experience in handling regulatory investigations and associated employee issues, we have leading criminal defence capability covering anti-corruption and bribery, anti-money laundering, fraud (financial and tax), antitrust, sanctions and insider dealing.
We bring a deep understanding of both the technical legal requirements of multiple jurisdictions and the practical concerns and investigative methods used by government regulators and criminal prosecutors.
We advise clients across the world before, during and after any regulatory investigation. Prioritising the need to avoid enforcement action, we seek to guide clients through practical processes such as data analysis, data transfer, interviews, requests for information, producing preliminary and final reports and all employee-related issues.
