In December 2007, Hilton's grandfather Barron Hilton pledged 97 percent of his estate to a charitable organization founded by his father, the Conrad N. Hilton Foundation. An immediate pledge of $1.2 billion was made, with a further $1.1 billion due after his death. He cited his father's actions as the motivation for his pledge. According to reports, the potential inheritance of his grandchildren is sharply diminished.
