Why It’s Important: Gates, who is the co-founder of Microsoft, took to Twitter to thank Buffett for the donation.

“I’m grateful for Warren’s gifts to support the foundation’s work and for our many years of friendship. When he decided in 2006 to make these gifts, it moved me to tears. It still does,” Gates said.

Gates Foundation CEO Mark Suzman highlighted the amount of money that has been contributed by Buffett to the non-profit.

“Today, we received Warren Buffett’s annual gift, bringing his contributions to more than $36 billion since 2006. Thank you, Warren for your continued generosity and your belief in the mission of the Bill & Melinda Gates Foundation,” Suzman said.

Over the years Buffett and Gates have been philanthropic with their money, one of the items noted by Benzinga is that when the wealth of the two friends and billionaires is combined, it now lags behind the fortune of Tesla CEO Elon Musk.
