"Warren Buffett is continuing to make good on his promise to donate most of his $44.1 billion to charity. The third richest person in the world gave about 18.4 million of his company’s Class B shares, valued at $1.52 billion, to the Bill and Melinda Gates Foundation, Bloomberg Businessweek reported Saturday. Giving generous donations to the Gates Foundation, which aims to improve education and health care has become an annual tradition for Buffett, a plan initiated in 2006, according to the Associated Press."
