The Facebook Inc. road show, a final pitch to investors, will begin on Monday, a couple weeks ahead of a tentative IPO date of May 18. Facebook filed its preliminary paperwork in February and, in early April, bought photo-sharing app Instagram for $1 billion — a deal CEO Mark Zuckerberg reportedly made by himself. The Wall Street Journal writes that Chief Operating Officer Sheryl Sandberg and Chief Financial Officer David Ebersman will handle most of the road show meetings while Zuckerberg does pretty much whatever he wants. Experts believe that the IPO could raise as much as $10 billion.
