Loan 4573 downrated to A from A+ with no payments made

It would seem to me that this withholding was exceptional and related to a particular problem with this borrower. Consider the problems of FC systems and the calculation and distribution of interest payments. On the old loan the existing lenders get interest paid up until the next due repayment, and that is in the T&Cs and cannot be fiddled with. So it is difficult for FC to demand repayment while interest is being paid on the money. But also the interest payments on the new loan are fixed and monthly and start accumulating as soon as the borrower accepts the loan - all the new lenders expect full interest from the start date and if some part of the money is withheld by FC it would not be easy to pay some lenders and not others (which ones?) nor to split the whole loan into two tranches and pay lenders at one rate to start with and another rate when the full amount was given. And what happens at the end of the loan? I am pretty sure that FC's system and reconciliations could not cope with this, unless the money was withheld but the borrower was expected to pay the full interest on it. Nor would FC wish to pay the interest.
I remember in a past life that one of the biggest problems of having a dynamic sales and marketing department was that they would invent super new promotional schemes and go ahead with them without checking that the billing system could actually bill the customers for it, resulting in manual billing. The solution was to require an IT sign off for any new promotional deal, which rather limited things. I reckon that FC gets into similar problems.
