John R. Mirvish is a Senior Financial Analyst and Government Affairs Advisor in the Washington DC office of Mayer Brown’s Financial Services and Regulatory Enforcement practice. He focuses on legislation, regulation, and public policy matters affecting domestic and foreign banking operations in the United States. John also concentrates on factual analysis in complex litigations, federal and state enforcement matters, and Congressional, regulatory, and internal investigations involving domestic and foreign financial institutions. John has been working on these issues for more than 20 years, including more than 15 years at other large global law firms prior to joining Mayer Brown in 2006.

John has supervised several complex internal investigations and managed client responses to enforcement matters involving federal regulatory agencies and Congressional committees.  In this regard John has worked on several cross-border matters involving US sanctions, including an internal review arising from a non-US bank’s funding of its overnight liquidity requirements through USD-denominated short-term deposits sold to certain US-sanctioned financial institutions; an internal review relating to a non-US bank’s USD-denominated trade finance transactions with business entities in US-sanctioned countries; an internal review of a non-US bank’s process for blocking and controlling transactions of a US-sanctioned individual; and a comprehensive review of potential US sanctions implications for a non-US bank with accountholders in certain US-sanctioned jurisdictions.  In addition to internal investigations relating to sanctions, John has been involved in internal investigations and enforcement matters involving cross-border transactions that potentially involved politically exposed persons, cross-border financial fraud, anti-money laundering regulations, and tax issues.  In connection with his work on these matters John has extensive experience in the e-Discovery process and advised a client in establishing its own internal e-Discovery platform and protocol for a complex cross-border investigation.

John also has extensive experience with the federal legislative process and recently, John has been assisting clients with issues arising from the passage of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the Foreign Account Tax Compliance Act. Prior to that, John assisted clients with matters relating to other financial services, corporate, and insurance legislation, including the Gramm-Leach Bliley Act, the Sarbanes-Oxley Act, and the Terrorism Risk Insurance Act.
