(USA) Provisions in a company's organisational documents that are designed to discourage undesired takeover bids. See 'Blank Cheque Preferred Stock', 'Poison Pill', 'Shark Repellent' and 'Staggered Board of Directors'. In the UK, company law combined with the provisions of the Takeover Code, which discourages attempts to frustrate bona fide takeovers, would likely result in such provisions being unenforceable.
