How do Google's shares work?
Google has reported a 60% rise in profits for the first three months of the year.
The world's biggest internet search group made $2.89bn (£1.8bn) in the three months to March.
The group also announced it would double the number of shares in circulation to entice new investment without diluting the board's overall control of the company. It is a process called a stock split.
Justin Urquhart Stewart, director and cofounder of Seven Investment Management told the BBC how the stock split will work.
