This course primarily addresses organization and operation of commercial organizations in the Anglo-American community. Preliminarily, sole proprietorships and partnerships are considered, after which corporations-for-profit are emphasized with some attention to business trusts and non-profit corporations. In the corporate context, duties of promoters, directors, officers, and other insiders are considered. Availability in the U.S. of the derivative action is treated in terms of both unincorporated and corporate forms of organization. Also treated are the basics of securities regulation at the federal and state levels in the U.S. and the provincial level in Canada.
