Colby has extensive experience defending against activist investors. This includes litigating and advising boards on proxy voting, governance, anti-takeover defenses, board elections and fiduciary duties.
In the civil litigation area, Colby’s notable asset management matters include:
- securing dismissal of putative class action claims brought under Sections 11 and 12 of the Securities Act of 1933 against one of the industry’s largest managers of ETFs for alleged misstatements and omissions in offering documents related to the risks of so-called “flash crashes”
- securing summary judgment dismissal of a $440 million claim alleging Rule 10b-5 fraud claims against one of the nation’s largest mutual fund advisers in an MDL proceeding consolidating more than 80 putative class actions
- representing an institutional money manager in the successful defense of $360 million fraud, RICO, breach of contract and other claims brought by a corporate pension plan in a private arbitration
In the regulatory arena, Colby also has defended asset managers in dozens of investigations by the SEC, the DOJ, and state and self-regulatory agencies relating to a wide range of business and compliance issues, including conflicts of interest, sales and distribution, portfolio management, trading, code of ethics and back office issues. Some examples include:
- representing a special committee of the board of directors of a large custody bank in an independent investigation of pay-to-play allegations
- defending and negotiating the successful resolution of a SEC investigation into certain fixed income trading practices, as well as conducting several internal investigations into a range of other trading issues at multiple advisers
Colby’s practice is not limited to the asset management industry. He also has represented high-tech, life science, accounting and other firms in matters involving alleged fraud and securities law violations; theft of confidential information and trade secrets; covenants not to compete and “employee raiding” litigation; SEC and other regulatory investigations; and Delaware litigation arising from mergers and acquisitions. Colby led a team in three trial wins that obtained permanent and injunctive relief from the Delaware Chancery Court in a dispute over a developing technology, as well as related dismissals of two bankruptcy filings as bad faith litigation tactics.
Colby is active in various pro bono matters and has been recognized for his work in domestic abuse prevention cases. Colby led a Skadden team as part of a consortium of firms in obtaining a historic settlement valued at over $20 million for Indian welders and pipefitters brought to the Gulf Coast after Hurricanes Katrina and Rita in the nation’s largest-ever labor trafficking suit.
