Donation equaling to $1.5 billion of Berkshire Hathaway Inc stock has been given by a billionaire investor Warren Buffet to the Bill and Melinda Gates Foundation and to four family charities on Wednesday. After faithfully fulfilling the promise made in 2006 by bestowing the stocks of Berkshire to charities, Buffet owns $36.1 billion worth stock in Berkshire according to Wednesday closing prices.  
 
Buffett, the person who has turned Omaha and Nebraska-based Berkshire into a corporation with close to 80 businesses, possesses 25.8% shares of Berkshire, and 31.6% of the company's voting power. 

It should be reminded that Buffet was called the world’s second-richest person after Bill Gates by Forbes magazine in March.
