Answer:
increase the effective interest rate of borrowing
Step-by-step explanation:
Cost of debt refers to the total cost a company incurs for raising debt which includes fixed coupon rate payments to bondholders.
Cost of debt is calculated using the following formula:
wherein
= Cost of debt
I = annual rate of coupon payment
t= tax rate
NP = Net proceeds which is par value less issue expenses
when NP is taken as the base, while calculating cost of debt, it is termed as effective interest rate.
So, bond issue costs reduce the net proceeds and thus, increase the effective interest rate of borrowing for the issuer company.
