The noble Lord must accept that my original answer encompassed this concept, but I will spell it out in more detail. Dolerite was a securitisation structure similar to Granite. It was used by Northern Rock to fund its commercial mortgage book. All bonds under that structure have now been redeemed. Therefore, Dolerite is entirely irrelevant to Northern Rock. As I cannot be any more explicit than that, I hope the noble Lord will forgive me.
