You have a lease on an oil and gas property with 87.5% NRI that delivers your firm annual profits of $400,000 for five years, with equal production in each year (you will need to think about how to use this assumption). At the end of five years, production will cease. Your firm incurred debt of $900,000 in intangible drilling costs (IDC) on this property. These can be expensed 100% in the first year or capitalized into the property's book value of $1.5 M. If they are added to the property's book value, they become part of the property's cost depletion deduction. Is it advantageous to completely deduct ("expense") the IDCs completely in the first year? Why or why not? Calculate the cost-depletion and adjusted basis for each year. Assume a corporate tax rate of 30% and excess tax liability in each year, with a discount rate of 15%. Calculate the value of the tax shield that the cost-depletion allowance represents
