We defend our clients in investigations by the SEC, CFTC, DOJ, state attorneys general, the UK FCA, other federal and state civil regulators, and self-regulatory agencies such as FINRA and NYSE. We assist clients during regulatory examinations and conduct internal investigations of sensitive matters.
