JR: Facebook has been having a difficult time recently. It is being scrutinized because of (1) news that Russia used Facebook to meddle in the 2016 U.S. presidential election, (2) the proliferation of fake news and violent content, and (3) prominent investors warning that social media is addictive and questioning its utility to society. Facebook is now under renewed scrutiny because it was reported that Cambridge Analytica collected data on 50 million Facebook users without consent. Following the Cambridge incident, Facebook is being investigated by the FTC. What are your views of Facebook's business going forward, its prospects for growth, and its current valuation? At $154, shares are trading at less than 18 times 2019 GAAP EPS estimates (and only 16 times ex-cash). Also, are you satisfied with Facebook's management response to the Cambridge Analytica scandal so far?
