Question:

Michael Dell founded PCs Limited in 1984. The firm had an initial public offering (IPO) in 1988, under the name Dell Computer Corporation, which enabled the company to raise money it used for expansion. In 2013, Michael Dell and a private equity firm bought back ownership of the company from its shareholders. Dell is now a privately owned firm. What would motivate Michael Dell to make this change?
