Ms. Winfrey's net worth is down by $100 million to $2.9 billion from her appearance on the billionaires list earlier this year. Her lost is mainly due to her investment in Weight Watchers, which is not off to such a good start, as shares have fallen significantly since she took a 10% stake in October 2015. The company's CEO resigned in September; Winfrey will help with the search for a replacement.
Mr. Smith's net worth remains at $2.5 billion. Earlier this year he announced a $50 million gift to his alma mater Cornell University, which renamed its school of chemical and bioengineering after him. In June he was named chairman of Carnegie Hall. He also contributed $20 million to the Smithsonian National Museum of African American History and Culture, making him the museum’s second-highest private donor.
