Our Approach
Our approach is pragmatic and flexible. And it's always tailored to an end-game strategy that matches the nature of the proceeding with our client's broader regulatory and business position. We're known for our ability to take tough cases to trial and win. We frequently persuade regulators and prosecutors to walk away from investigations without taking action — or, alternatively, to resolve them on terms favorable to our clients.
We've achieved extraordinary success protecting clients from a broad range of investigations and enforcement actions initiated by the Securities and Exchange Commission, Department of Justice, Financial Industry Regulatory Authority, state attorneys general, and other regulators and agencies. These matters range from informal inquiries and formal investigations to administrative and judicial enforcement proceedings.

We represent mutual funds, institutional investors, public pension funds, trusts, investment advisors, and individuals as claimants in securities and antitrust class actions and regulatory settlements throughout the nation. We also represent clients by evaluating participation in non-US investor actions and settlements, which have ballooned throughout the world in the wake of the Supreme Court's Morrison decision.
