Answer:
The firm's after cost of debt is 7.48%
Step-by-step explanation:
Floatation cost increases the cost because a diminished portion of the whole amount was received.
Given that;
r = 9%
t = 21%
f = 5%
After tax cost of debt = r ( 1 - t ) / ( 1 - f )
0.09 ( 1 - 0.21 ) / 1 - 0.05 )
= 0.0711 / 0.95
=0.0748421053
= 7.48%
