News bites: Zuckerberg's net worth fell after stock plunge

Facebook CEO Mark Zuckerberg's net worth fell to $10.2 billion after the social network's shares plummeted Thursday, Bloomberg reports.

Zuckerberg had acknowledged to employees earlier this month that it might be painful to watch investors sell their shares after lockups expired, according to The Wall Street Journal.

Facebook's stock beating on Thursday was the second largest post-lockup decline among companies that have gone public since 2011, with Zynga taking the top spot, Bloomberg reports. 

Agencies' monitoring of federal employees' communications has sparked concern among privacy advocates, The Washington Post writes. 

An accountant for Samsung testified Thursday that Apple had inflated the Korean company's profit margins for smartphones and tablets in its patent suit, Reuters says.
