This user-friendly casebook covers the changing landscape of securities regulations, dealing concisely but comprehensively with the current state of the law, as well as with expected modifications to securities regulation. The philosophy for the presentation of materials is that securities law is tricky, and most students need a straightforward guide through the maze. Coverage of the Securities Act of 1933 and the Securities Exchange Act of 1934 is kept separate, and care is taken to distinguish the different perspectives of the planner and the litigator. The Ninth Edition has been completely revised to reflect the adoption or revision of a number of exemptions from '33 Act registration, the advent of digital currency, the prosecution of hackers for insider trading, the materiality of corporate ethics code violations, and a myriad of other topics, all explained as an integrated part of the overall structure of securities regulation rather than as confusing add-ons. The Ninth Edition also adds or discusses the important securities decisions issued since the last edition. These include Omnicare, Inc. v. Laborers District Council Construction Industry Pension Fund, Salman v. United States, and Kokesh v. SEC.
