Final answer:
The remaining life left for Grey Fox Aviation Company's bonds is estimated to be 8 years. The coupon rate needed for new bonds to be issued at par is 16.035%.
Step-by-step explanation:
In order to estimate the remaining life left for Grey Fox Aviation Company's bonds, we need to compare the maturity date with the call date. If the call date is earlier than the maturity date, the bonds are likely to be called. Therefore, the best estimate of the remaining life left for the bonds is 8 years.
To issue new bonds at par, the coupon rate must be equal to the current market interest rate. Since the current market price is $1,160.35 and the par value is $1,000, the difference is the total interest payment over the bond's life. We need to find the coupon rate that would make this interest payment equal to zero. We can use the following calculation: Coupon rate = (Par value - Market price) / Par value = ($1,000 - $1,160.35) / $1,000 = -0.16035
So we must modify the sign to make it positive and the coupon rate that must be issued at par is 16.035%.
