Senior leaders across Wall Street come and go, but one executive that's stayed put over the years is Bank of America's Tom Montag.

Montag oversees the firm's global banking and markets businesses and is one of Bank of America's most powerful figures. He's long been speculated as a potential successor to CEO Brian Moynihan.

Business Insider is mapping out the divisions overseen by Montag. In sales and trading across fixed income and equities, that amounts to more than $13 billion in annual revenue for the bank.

On the investment banking side, that business has rebounded after seeing revenue and market share take a nose dive last year.

Business Insider spoke with insiders, ex-employees, consultants, and other industry experts to gain insight into the reporting structure. We've focused on front-office execs that bear the primary responsibility for driving the group's revenue - no back-office roles appear in our chart.
