Without doing any work at all, it would be impossible for an investment banker to tell anyone what the possibilities are. That would be like a doctor telling a patient that he will live, without giving him a physical examination. There are many possible reasons for a good situation not being financed. It is not the responsibility of the consultant to assume these risks which are the normal risks of the party seeking the capital. Instead he receives only a small percentage of the money for his work.
Many possibilities exist over which the consultant has no control.
The lender and borrower, or investor and recipient, may not offer terms or conditions the other will accept. During the negotiations the political, physical or economic conditions may change. None of these are the fault of the investment banker. For each of these questions several different contradictory answers can be constructed in a dialectic which assumes different conditions and circumstances. His references from satisfied clients.
