12. (Oil depletion allowance 9) A wealthy investor spends $1 million to drill and develop an oil well that has estimated reserves of 200,000 barrels. The well is to be operated over 5 years, producing the estimated quantities shown in the second column of Table 2.6. It is estimated that the oil will be sold for $20 per barrel. The net income is also shown.

The allowance is deducted from the net income to determine the taxable income. The investor is in the 45% tax bracket. (a) Complete Table 2.6 and show that the total depletion allowance exceeds the original investment (b) Calculate the PV and the IRR for this investment. Assume an interest rate of 20%
