(note: round your ytm rate to two decimal place.)

Consider the following calculations

Explanation:

Answer a.

To calculate the after-tax cost of debt, multiply the before-tax cost of debt by (1 - T).

Answer b.

Before-tax Cost of Debt = 12.50%

After-tax Cost of Debt = 12.50% * (1 - 0.25)

After-tax Cost of Debt = 9.38%

Answer c.

Face Value = $1,000

Current Price = $1,329.55

Annual Coupon Rate = 12.00%

Annual Coupon = 12.00% * $1,000

Annual Coupon = $120

Time to Maturity = 15 years

Let Annual YTM be i%

$1,329.55 = $120 * PVIFA(i%, 15) + $1,000 * PVIF(i%, 15)

Using financial calculator:

N = 15

PV = -1329.55

PMT = 120

FV = 1000

I = 8.1213%

Annual YTM = 8.1213%

Before-tax Cost of Debt = 8.1213%

After-tax Cost of Debt = 8.1213% * (1 - 0.25)

After-tax Cost of Debt = 6.09%
