Facebook chief executive Officer Mark Zuckerberg has just made his first big share sale to fund his family's philanthropic initiative. Though he will be selling a very small portion of his Facebook stock, he is taking major steps towards working for his charity foundation. The sale of more than 760,000 shares of Facebook stock, valued at about $US95 million ($125 million), was made by Chan Zuckerberg Initiative Holdings and the Chan Zuckerberg Foundation, accordingto reports. In December of last year, Zuckerberg moved some of his Facebook shares to the Chan Zuckerberg Initiative, a for-profit corporation whose mission is to "advance human potential and promote equality for all children in the next generation.

" Zuckerberg announced the plan along with his wife, Priscilla, after the couple had their first baby in December. The charity group made $95 million by selling 767,905 shares on Wednesday and Thursday according to reports. This is the first time he's cashed out since the initial unveiling of the plan. He has said that he will sell or gift no more than $1 billion of Facebook stock each year. Zuckerberg still owns well over 400 million shares of Facebook stock.
