C — Citigroup Inc.

Citigroup is a global financial powerhouse that orchestrates the movement of over $6 trillion in daily transaction volume, serving as the essential connective tissue for the world's most complex multinational corporations. The firm services 90% of the Fortune 500 through a proprietary network that includes direct membership to over 270 cash-clearing centers and a footprint that spans 94 countries. After a checkered history operating as an overly complex, disjointed firm, it has taken steps to streamline operations, resulting in organization across five segments: services, markets, banking, wealth, and US personal banking.
