Microsoft's (MSFT 1.65%) fortunes may be ebbing, but it still generates a ridiculous amount of money. Over the last 12 months, it earned $91 billion in revenue, ranking 26th among S&P 500 companies. What does the 40-year-old company do with all this money? The slideshow below provides an answer.

Viewers of the slideshow will learn three interesting points, among other things, from scrolling through it:

  • First, Microsoft has paid more in taxes over the last four quarters than all but four publicly traded companies: Apple, General Electric, ExxonMobil, and Wal-Mart.
