The document outlines several defensive tactics used by companies to avoid acquisitions, including divestures, spin-offs, split-ups, golden parachutes, selling crown jewel assets, poison pills, and white squires. Divestures involve selling assets to make the company less attractive. Spin-offs separate out assets into new shares for existing shareholders. Split-ups similarly distribute shares in new business lines. Golden parachutes provide large payouts to managers if acquired. Crown jewel sales remove major assets. Poison pills dilute stock to transfer wealth from bidders. White squires are friendly parties that buy enough shares to block a hostile takeover.
