"Mark Zuckerberg hates the idea of going public," says David Kirkpatrick, author of "The Facebook Effect," in this video interview with The Deal magazine. The Facebook Inc. CEO is in no hurry to take on the complexities of running a public company, which include regulatory headaches, public responsibilities and short-term financial pressures. Zuckerberg and some of his social media peers are keeping their companies private as long as possible, thanks to unprecedented access to capital and active secondary markets that provide some liquidity and valuations crucial to M&A negotiations. But, as Goldman Sachs & Co.'s recent investment in the fast-growing social network first brought to light, Facebook expects to start filing public financial reports no later than April 30, 2012 to comply with SEC regulations.
