Hamdi Ulukaya, the founder and chief executive officer of yogurt maker Chobani, tells the Associated Press that he will donate at least half of his fortune, estimated at $1.41 billion.
The Turkey-born entrepreneur said he is signing on to the Giving Pledge, Bill Gates and Warren Buffett's campaign to persuade billionaires to commit a majority of their wealth to charitable work.
Mr. Ulukaya, whose company fueled the surging popularity of Greek-style yogurt, said his philanthropic focus would be helping refugees around the world. He plans to finance a foundation called Tent that will raise awareness about refugee crises and provide medical, educational, and other aid to displaced people. Mr. Ulukaya pledged $2 million last fall to assist Syrian and Iraqi refugees.
