Bill Gates won't occupy the top spot on the world's rich list when Forbes magazine releases its annual ranking Wednesday, according to multiple reports.
The Microsoft founder is expected to finish second place, but not because of any faulty financial planning - Gates has donated $28 billion - nearly a third of his wealth - to charities through the foundation he runs with his wife, Melinda.
Mexico billionaire Carlos Slim is expected to lead the way, with Gates following him. Investor Warren Buffett rounds out the top three, according to reports.
