Coupon rate is the yearly interest earned by a loan and it can be calculated with

where i is the annual interest and p is the par value of the bond or the initial loan amount.
For this particular case, since the semiannual payment is $28.50, then the annual payment is 2 x 28.50 = $57.00.
Thus, we have

From this, the coupon rate is 0.057 x 100% = 5.7%.
Answer: 5.7%
Answer:
The correct answer is Product Development Stage.
Explanation:
If any of the changes are required to be incorporated in a design, the best point of attempting these changes is in the product design phase such that the considerations are included from the initial stage and the design effort is not wasted.
a.
WACC is calculated as –
WACC = (Weight of common stock X Cost of common stock) + (Weight of preferred stock X Cost of preferred stock) + (Weight of debt X After tax cost of debt)
WACC = (64% X 13.4%) + (9% X 6.4%) + (27% X ((1- 40%)*8.1%))
WACC = 10.46%
b. After tax cost of debt is calculated as –
After tax cost of debt = (1- tax rate) X cost of debt pre-tax
After tax cost of debt = ((1- 40%)*8.1%))
After tax cost of debt = 4.86%
