Some facts about Wells Fargo:
— It is the country's fourth-largest bank by assets, with roughly $1.4 trillion. That puts it behind JPMorgan Chase, Bank of America and Citigroup. It is the biggest by stock market value — about $174 billion at Thursday's close.
— In 2011, it earned $15 billion. It reported revenue of $81 billion, third behind JPMorgan and Bank of America.
— Wells is the biggest player in U.S. mortgages, making roughly a third of all mortgage loans, according to Inside Mortgage Finance.
— Of the six U.S. megabanks, Wells is the only one trading above book value. That means its value on the stock market is more than the underlying value of all its parts.
