Industry Recognition

Ropes & Gray combines strengths across disciplines, industry knowledge and legal savvy litigating precedent-setting cases alleging investment mismanagement, breach of fiduciary duty, statutory violations, and other claims by private plaintiffs and government regulators.

Among our recent successes for fund and advisor clients, we handled matters dealing with: 

  • Excessive Fees. Successfully defended the fees of the Oakmark Funds in the U.S. Supreme Court case of Jones v. Harris Associates, which set the standard by which “excessive fee” claims under Section 36(b) of the Investment Company Act are measured, endorsed the primacy of independent fund directors in setting fees, and rebuffed attempts by plaintiffs’ lawyers to encourage increased judicial scrutiny of fees. Defeated similar claims against Ameriprise Financial in the 8th Circuit in the first appellate interpretation of Jones
  • Subprime Mortgage Investments. Defended State Street Global Advisors (SSgA) in multi-district litigation over subprime mortgage-related investments in fixed income funds. The multiple federal actions asserted by investors included breach of fiduciary duty claims by institutional investors, ERISA class actions by multiple plans, and securities class actions alleging misleading mutual fund prospectuses. We also represented SSgA in related investigations by the SEC and other federal and state regulators. 
  • Securities Class Actions. Won dismissal of securities class actions alleging prospectus violations against funds, board members, and investment advisors, including claims against ProShares, the market’s leading provider of leveraged and inverse ETFs.  
  • Closed-End Funds. Defeated attempts by shareholders to seize control of multiple closed-end mutual funds through litigation and proxy fights. 
  • Derivative Claims. Won dismissal of shareholder derivative suits against fund advisors, officers, and board members, and regularly advise independent directors in their handling of derivative demands.
  • Market Timing and Revenue Sharing. Led the industry in representing more funds, boards, and advisors than any firm in investigations by the SEC, NASD/FINRA, the N.Y. Attorney General, the Department of Labor, and other regulators regarding market timing, revenue sharing, and other mutual fund practices. In the related multi-district civil litigation, we argued on behalf of the industry and won dismissal of all derivative cases, thus removing every independent director and trustee from the cases as defendants.
  • Foreign Corrupt Practices Act. Conducted multi-jurisdictional, FCPA-related internal investigations on behalf of clients, in connection with SEC and Department of Justice investigations. Developed FCPA compliance programs and conducted FCPA reviews for multinational clients.
