Bill Gates announced plans Thursday to give away “virtually all” of his estimated $200 billion fortune.

At the age of 69, the co-founder of Microsoft has expressed his intention to distribute his wealth over the next two decades. His goal is to do so before the closure of the Gates Foundation, which was established with his ex-wife Melinda, by the end of 2045.

“People will say a lot of things about me when I die, but I am determined that ‘he died rich’ will not be one of them,” Gates wrote.

“There are too many urgent problems to solve for me to hold onto resources that could be used to help people.”

Gates and his former wife established their foundation in 2000, with plans to continue its philanthropic work for many decades after their deaths.

The foundation, one of the world’s largest charitable organizations, has reportedly already given away more than $100 billion since its founding.
