Answer:
a. Cash proceeds $960
b. Cost of Debt Before tax 9.4% and after tax 6.8%
c. Cost of Debt Before tax 9.39% and after tax 6.76%
Step-by-step explanation:
a.
Cash proceed from the sale of bond is the net selling price and the floating cost of the bonds.
Cash proceed = Selling price - Floating cost = $980 - $20 = $960
b.
Yield to maturity is the annual rate of return that an investor receives if a bond bond is held until the maturity.
Yield to maturity = [ C + ( F - P ) / n ] / [ (F + P ) / 2 ]
Yield to maturity = [ $90 + ( $1,000 - $960 ) / 20 ] / [ ( $1,000 + $960 ) / 2 ]
Yield to maturity = 9.4%
Cost of debt before tax = 9.4%
Cost of debt after tax = 9.4% ( 1 - 0.28 ) = 6.8%
c.
Yield to maturity = [ C + ( F - P ) / n ] / [ (F + P ) / 2 ]
Yield to maturity = [ $90 + ( $1,000 - $960 ) / 20 ] / [ ( $1,000 + $960 ) / 2 ]
Yield to maturity = 9.39%
Cost of debt before tax = 9.39%
Cost of debt after tax = 9.19% ( 1 - 0.28 ) = 6.76%
