WASHINGTON (AP) Federal regulators have fined Facebook $5 billion for privacy violations and are instituting new oversight and restrictions on its business. But they are only holding CEO Mark Zuckerberg personally responsible in a limited fashion.

The fine is the largest the Federal Trade Commission has levied on a tech company, though it wont make much of a dent for a company that had nearly $56 billion in revenue last year.

As part of the agencys settlement with Facebook, Zuckerberg will have to personally certify his companys compliance with its privacy programs. The FTC said that false certifications could expose him to civil or criminal penalties.
