Procurement - Do you ask for past financial statement in you RFP?

New supplier are more at risk, or represent a uncertainty.
Old one can also have problem you are unaware.

We have a preferred vendor list for suppliers we've been dealing with since years and so far we never had any incident that any of them started with a good financial record and end with a bad record. Of course it might happen but until we sense there is anything wrong, we can't request from them everytime a financial statement because you develop some kind of trust with people and you need to make them feel that you trust them in order for them to have a level of comfort as well. For new suppliers, we always ask for financial statements.
