This practical guide tells you how to make filings of a Schedule 13D or Schedule 13G. It includes a step-by-step list of what a tender offeror and a target company should do in a tender offer. There are three lists of the steps: a friendly tender offer, a hostile tender offer, and a hostile tender offer that becomes friendly. Corporate lawyers, securities lawyers, investors that take greater that 5% positions in public companies, companies that are subject to a Schedule 13D or Schedule 13G filing, target companies in a tender offer, and law schools will find this work helpful.
