Det er med andre ord ikke muligt af en bestemt langfristet rating, her AAA/Aaa, helt nøjagtigt og uændret for alle ensratede banker og over tiden at udlede bestemte refinansieringsomkostninger.
In other words, specific refinancing costs cannot be deduced precisely and unchangingly for all similarly rated banks and over time from a specific long-term rating, in this instance AAA/Aaa.
