Wal-Mart Heiress Helen Walton to Donate Most of Her Stock

The death of Wal-Mart Stores heiress Helen Walton will not require sales of a large block of the company's shares, her family said in a statement on Tuesday.

Instead, a significant portion of the shares owned by Helen Walton's estate will pass, over a period of years, to charities, the family said.

Helen Walton, the widow of Wal-Mart founder Sam Walton and the matriarch of one of the richest families in U.S. business history, died on April 19 at age 87. At the time of her death, Forbes listed her as the 29th richest individual in the world with a personal fortune worth $16.4 billion.
