Patty concentrates her practice on business finance and transactional matters, as well as corporate governance and compliance, with a focus on representing energy industry clients. She handles matters such as structured commercial transactions, corporate governance and compliance policy development, debt financing, derivatives, and M&A transactions, including acquisition of energy contract portfolios. In recent years, Patty has assisted energy clients, as well as other U.S. and global corporations, with evaluating the impact of the financial reform legislation (Dodd-Frank Act), and related Commodity Futures Trading Commission (CFTC) and global bank regulations that affect commercial business operations, transactions and corporate development strategies. Patty has extensive experience representing buyers, sellers, investors, lenders and borrowers in a wide variety of regulated and unregulated industries. This gives Patty the perspective to focus on important transaction structuring and negotiation points, and to propose practical solutions to achieve the client's business objectives.
