Securities Litigation/Enforcement

A history of creativity and performance

Clients choose Dechert to defend them in securities and other shareholder litigation based on our history of creative representation and stellar performance.

Our lawyers represent public companies and their executives, officers, directors and board committees, as well as broker-dealers, mutual fund companies and other financial institutions, across the spectrum of securities litigation matters.

These include class actions, shareholder derivative suits, mutual fund litigation, M&A litigation, banking and financial institution litigation, broker-dealer disputes, internal investigations, non-public regulatory investigations, disciplinary hearings, inquiries and enforcement proceedings.

We frequently appear both in court and before federal and state securities regulators: the Securities and Exchange Commission (SEC), Commodity Futures Trading Commission (CFTC), Department of Justice (DOJ), self-regulatory organizations such as the Financial Industry Regulatory Authority (FINRA), state agencies and attorneys general, and all of the major stock exchanges.

Our securities litigation team — which is one of the largest in the U.S. — covers all major jurisdictions and market sectors. In addition to handling U.S.-based matters, we have either represented clients or coordinated their representation globally, including in notable jurisdictions such as the UK, France, Germany, Russia and Hong Kong.

Many of our lawyers previously worked in high-level government enforcement positions. They’ve been U.S. Attorneys, Assistant U.S. Attorneys, assistant district attorneys and SEC officials.

Mutual fund litigation

We are a leader in the successful representation of asset managers, banks and other lenders, broker-dealers, commodities and derivatives firms, fund complexes, hedge funds and insurers, along with boards and individual directors. Our litigators have guided financial clients through regulatory and other disputes arising worldwide.

Regulatory investigations and enforcement

Our M&A litigation clients include acquirers, sellers, bidders, corporate officers and directors, special board committees, investment banks and advisers, venture capitalists, individual investors, private equity firms, hedge funds and other stakeholders. We also represent deal parties in inquiries and investigations pursued by the SEC and stock exchanges, as well as in arbitration and other forms of alternative dispute resolution.

Securities class actions and direct fraud

We represent investment advisers, fund companies, boards and individual trustees, broker-dealers and industry organizations in virtually all types of litigation and enforcement matters. In litigation, we regularly defend fund industry clients in high-stakes matters under a host of federal and state laws and at all levels of the federal and state court systems. We are also on the front lines of defending enforcement investigations and internal investigations, and have decades of experience with the full range of fund-related regulatory proceedings.

Shareholder derivative litigation

We defend financial firms, public companies, investment advisers and other institutions subject to oversight and investigation by the SEC and other government agencies. Our long experience — combined with our deep knowledge of the law and industry practices — helps us develop strategies that are both effective and inventive.
