Facebook's Sandberg joins board as first female member

Facebook's Sheryl Sandberg has been elected to the board of directors after four years at the social networking company. She is the first female member of the board.

Facebook's chief operating officer Sheryl Sandberg has joined the board of directors, the company announced on Monday.

Sandberg, who oversees Facebook's business operations --- such as sales, marketing, legal, public policy and communications --- was hired in 2008, after chief executive Mark Zuckerberg poached her from Google to join the burgeoning social network.

She will have voting privileges on the board following her election to the position by existing board members.

An 8-K filing with the U.S. Securities and Exchange Commission confirms the appointment.

The timing of her appointment as the first female member of the board may not be so coincidental.

Right-hand woman to Zuckerberg, it comes only days after a Wall Street Journal piece described her as someone who "stamped out sexism" at the company, a second home to more than 3,500 employees.

"Her understanding of our mission and long-term opportunity, and her experience both at Facebook and on public company boards makes her a natural fit for our board," Zuckerberg said in a statement.

Sandberg herself described her role as something she is "deeply passionate about," adding that she feels "fortunate to be part of a company that is having such a profound impact in the world."

Facebook is thought to be in or around the 950 million user mark following its initial public offering in May.

Following difficulties with the Nasdaq stock exchange, Facebook dipped as low as $25 a share following its $38 initial share price.

It closed today down 3 percent at $32.06 a share.
