Google announced a very unusual corporate action. The two-for-one stock split will create a third class of shares with no voting rights. Since Google is a component of the S&P500, the split will have an impact there as well. Standard & Poor's index committee will accommodate the change by altering the S&P500 so that it will have 501 distinct members instead of 500.
On April 2, prices for Google common equity GOOG classes A and B will be halved for 12 March 2014 owners of record,
but investors will see their ability to have a say in the company greatly reduced... Google will pay a dividend using newly created class C stock, to existing holders of the company's class A and class B shares. The new class C shares will carry no voting rights.
