You are the president of an internet company that has enjoyed great success. You are considering expanding operations into the South American markets and need to raise $500 million of additional funding to do so.

The company treasurer, Chris, suggests an issuance of preferred stock instead. How is preferred stock different than bonds or common stock? What factors would you consider to decide the best way to raise $500 million?
