Learning to Invest / Reading Financial Statements

At the risk of asking too many questions on this board, I will post another one:

Can anyone offer advice on using Fool methodologies for evaluating financial institutions?  I keep running into the same problems with them.  For example, how does one take a Foolish flow ratio for financial institutions?

Here is a segment of Synovus's balance sheet.  Can anyone pull a Foolish flow number out of this?
