Fund Director’s Guidebook, Fourth Edition covers open-end funds (typically referred to as mutual funds), closed-end funds and exchange-traded funds. It is intended to assist directors of investment companies registered under the Investment Company Act of 1940 in fulfilling their responsibilities. Since 2006 when the third edition was published, there have been significant developments affecting funds in the wake of the 2008–2009 financial crisis and the resulting legislation, the Dodd-Frank Act. There also has been increased civil litigation involving funds and their service providers, and a more active role of the SEC and its staff in asserting securities law fund-related violations, including SEC enforcement actions against independent directors brought under the 1940 act’s compliance rule.
