Davos, Switzerland (CNN) -- The Bill & Melinda Gates Foundation will inject $750 million into the Global Fund to Fight AIDS, Tuberculosis and Malaria, Microsoft co-founder Bill Gates announced Thursday at the World Economic Forum.

The donation comes in the form of a promissory note, not as cash, which the Gates Foundation said "gives the Global Fund the flexibility and authority to distribute funds efficiently based on immediate needs."

"By supporting the Global Fund, we can help to change the fortunes of the poorest countries in the world," Gates said in a statement. "I can't think of more important work."
