Please help with the following: 9.b per 10 issued

Context:
The face value of the Bond may be raised or lowered in line with the 21% required to fund each related project funding need having purchased the underlying obligations to secure the capital. This structure would give the bank a large amount of capital under their management and control with related costs and charges, for the term best related to the bond issue, hopefully generating net gains (having paid the coupon) on a compounding basis for XXX Fund and themselves as investment managers over and above the obligations. (Depending on the agreed structure this could be as much as 9.b per 10 issued.)

I assume it means 9 bonds out of 10 but am not sure.

thank you!
