The document discusses mergers and acquisitions. A merger is the combination of two companies to form a new company, with both surrendering their stock to issue new stock. There are four main ways mergers can occur: purchasing assets, common shares, exchanging shares for assets, or exchanging shares for shares. Acquisitions occur when one company takes over another by purchasing over 50% of its stock. There are different types of both mergers like horizontal, vertical, and conglomerate, as well as acquisitions like friendly and hostile.
