Class C shares give stockholders an ownership stake in the company, just like Class A shares, but unlike common shares, they do not confer voting rights on shareholders. As a result, these shares tend to trade at a modest discount to Class A shares.
What is the difference between Class A and Class C Google shares?
The Class A stock carries one vote per share in every situation that counts up shareholder ballots. Class C shares have no voting powers at all. The Class B stock consists of so-called supervoting shares.
Is it better to own GOOG or GOOGL?
Class A shares get a vote while Class C shares do not. As A shares trade for more than C shares, you can infer the premium that the market places on this right.
