After years of ambitious mergers and inorganic growth, Bank of America (NYSE:BAC) has pledged to step on the corporate treadmill and lose some serious weight.

In 2011, CEO Brian Moynihan announced his ambitious plan to cut $8 billion in expenses by the middle of 2015. While it's easy to announce a cost-cutting program, implementing such a plan isn't quite as easy, and investors will be quick to hold Moynihan accountable if expenses aren't falling fast enough.

In this video, Motley Fool banking analyst David Hanson tells investors why Moynihan's comments during the bank's earnings conference call will be vital for B of A shareholders to hear.
