Facebook founder and CEO Mark Zuckerberg’s net worth rose US$3.1 billion to US$29.7 billion, according to ultra high net worth (UHNW) intelligence provider Wealth-X, on Facebook’s announcement of its 2013 Q4 earnings after market close on Wednesday.
Zuckerberg’s net worth is calculated after accounting for shares in public and private companies, residential and passion investments such as art, planes and real estate, and is based on the most recent publicly available disclosure of his shares and options in the Menlo Park social network firm.
At 29, Zuckerberg’s current fortune equates to more than $1 billion for every year he has lived.
The company's shares surged 12% to $59.98 in after-hours trading on strong 2013 mobile ad revenues.
Mobile ad sales rose to 53% of revenues from 49% in the previous quarter.
