Investment companies and investment advisory servcies have become a significant part of the financial system. They host and manage most of the retirement assets in this country and have spread their services abroad as well. This case book is designed to prepare students to practice in this area, including sensitizing students to the possible changes in money management and the legal adjustments to these changes. This book deals with the laws governing investment companies: their creation, structure, corporate governance, operations (including the distribution of shares and the management of the portfolios) and dissolution. In particular, this case book focuses on new structures that have evolved in this area, such as ETFs and money market funds. The purpose of this book is to prepare students, and lawyers who are not familiar with the subject area, to provide effective advice. In addition, it focuses on practicing in this area before the Securities and Exchange Commission.
