Actually the o/s share question was in jest. But the D&B's that I've seen would allow you to provide some details supporting that "their credit is fine."
I don't recall "fine" being one of the D&B rating categories, so I can only assume that some specific details of the report led you to that conclusion. Please tell us what they were.
Was it Timeliness of Historical Payments, Risk of Payment Delinquency, Risk of Financial Stress, Financial Condition, D&B Rating, Financial Strength, Paydex?
There's a ton of stuff even on the most basic D&B, isn't there?
