CHICAGO – Katten Muchin Rosenman LLP is pleased to announce that financial services attorneys Carolyn Jackson and Nathaniel Lalone have joined the firm’s UK affiliate, Katten Muchin Rosenman UK LLP, from Allen & Overy.

“With the adoption of the Dodd-Frank Act in the United States and similar initiatives in the United Kingdom and the European Union, the financial services market, particularly the derivatives market, is going through the most radical change in its history,” said Arthur W. Hahn, the Chicago-based chair of Katten’s Financial Services Practice. “Katten’s U.S. practice has been at the forefront of advising major institutions on this evolution. To that end, we are delighted that Carolyn and Nathaniel are joining us. They will enable us to service both our non-U.S. clients and our U.S. clients dealing abroad and will substantially enhance our London financial market capability.”

Ms. Jackson, who will join as a special counsel, has been a first vice president and manager of U.S. dollar derivatives trading at two major French banks and one U.S. commercial bank and has served as executive director and a member of the board of ISDA, all before attending law school. She spent over 10 years at Allen & Overy, where she was one of their leading derivatives lawyers, providing U.S. financial regulatory legal advice to leading banks, investment banks, hedge and private equity fund advisers, broker-dealers, derivatives service providers, trading platforms and clearinghouses.

“I am delighted to be joining the firm in London, where my objective will be to establish Katten as the premiere firm offering U.S. regulatory expertise during the European time zone,” said Ms. Jackson. “Being able to meet with European clients with EU and U.S. regulatory experts side-by-side will be critical to gaining trust and solidifying a long-term client base for Katten in London. The synergies and opportunities with the existing practices here in London and in our U.S. affiliate offices are tremendous.”

Mr. Lalone spent nearly four years at Allen & Overy, where he advised a number of European banks, brokerage houses, fund advisers and other financial institutions on a wide range of issues relating to U.S. securities, commodities and banking laws. He holds undergraduate and law degrees from Harvard as well as an M.Phil. and a Ph.D. from the University of Cambridge.

“I am thrilled to be joining Katten alongside Carolyn and I look forward to helping her build the leading U.S. regulatory practice here in London,” said Mr. Lalone.
