Facebook on Friday settled a lawsuit over issuing reclassified shares that some investors argued would decrease the value of their investment.

The class action shareholder lawsuit was intended to block Facebook from issuing reclassified C shares, which some investors argued could cause shares to lose billions of dollars of value when they were traded. The new C shares would be publicly listed but come with no voting rights.
