Few lawyers understand derivative products and the regulations that govern
them as well as Guy Dempsey. That understanding comes from extensive
hands-on involvement with complex derivative transactions and
documentation, detailed knowledge of current regulation and market
practices, and intimate familiarity with the consequences when derivatives go
wrong. Guy has spent nearly as many years as an in-house bank lawyer as
he has as an outside counsel, so he also knows how to give advice that is
practical as well as legally correct.
Practical advice for decision makers
Guy's deep product knowledge and in-house experience help him address
legal issues in ways that make business sense to clients. Sometimes, that
just means being able to understand and use market terminology; other
times, it may mean creating a compliance policy that actually reflects the way
business is done. He knows how to craft a legal solution to a problem that
takes into account the limitations of a client's systems and operational
capabilities. Because he represents all types of clients, he can help dealers
to understand what is important to end users, and end users to understand
what is important to dealers.
Guy has been involved in ISDA documentation projects dating back to the
drafting of the 1992 master and the credit support annex, and also
participates actively in relevant bar association and industry committee work.
He has been a speaker at numerous ISDA, PLI and industry presentations.
Before joining Katten, Guy was a managing director at Barclays Bank, where
he held a number of senior positions, including that of general counsel for the
Americas. He also served as managing director and counsel at Bankers
Trust Company, practicing law in both New York and London.
