Final answer:
The annual interest tax shield for Arnell industries is $784,000, and the present value of the interest tax shield is $725,925.
Step-by-step explanation:
The annual interest tax shield is calculated by multiplying the debt amount by the interest rate and the tax rate. In this case, the debt amount is $35 million, the interest rate is 8%, and the tax rate is 28%. So, the annual interest tax shield is:
$35,000,000 * 8% * 28% = $784,000
The present value of the interest tax shield can be calculated by discounting the annual interest tax shield at the relevant discount rate. Since the risk of the loan is the same as the bond, we can use the same discount rate as the bond's yield. Assuming a discount rate of 8%:
The present value of the interest tax shield is:
$784,000 / (1 + 8%) = $725,925
