The Microsoft founder will double the amount of money he gives away and close the Gates Foundation earlier than planned.

Microsoft co-founder Bill Gates will dramatically speed up his plans to give away most of his wealth, saying he will reduce his estimated $108 billion net worth by 99 percent over 20 years and prepare his eponymous foundation to stop operating by the end of 2045.

The Gates Foundation plans to give away $200 billion over the next 20 years before shutting down entirely in 2045, marking a new deadline for one of history’s largest and most influential charities.
