It appears they are still calculating "Coupon Dates", since the CTs are still alive...
Coupon Date
One of the dates on which bondholders are sent coupon payments. That is, the coupon dates are the dates on which bondholders receive the interest that they are guaranteed. Coupon dates are fixed for bonds, and usually occur twice a year.
that date has probably been there for the past 9 years, changing twice annually.
But hey, I hope i'm wrong.
cheers Mates!
