The takeover came about even after Sperry used a " poison pill" in the form of a major share price hike to dissuade the hostile bid, the result of which caused Burroughs to borrow much more funding than was anticipated to complete the bid. Certain internal divisions of Sperry were sold off after the merger, such as Sperry New Holland (1986, to
