The value of Facebook’s common shares, as well other key aspects of the stock-purchase plan such as timing and eligibility, remain unknown.
The Wall Street Journal has cited a $6.5 billion valuation for Facebook common shares in the DST deal. That translates to $14.50 a share, according to Oliveri’s calculations.
Facebook attempted to create a program for employees to sell shares to an unidentified investor in 2008, but the plan was put on hold as markets tanked. The initial plan limited the amount of shares an employee could sell to 20 percent of his or her holdings, or $700,000, whichever was less, according to a former Facebook employee.
