In order to approve a business loan, what would you ask to see besides a balance sheet?

If I were to decide between two companies who is more eligible to get a loan, what else would you ask to see besides their balance sheets? All the sheets show is accounts receivable, accounts payable, and things like ets, liabilities, and equity. Is there anything else more important to know in order to make a decision like this? Basically, what else could I ask for to get more information about the companies finances before making my decision?
