Therefore, it is necessary to adjust D4 . The number in bold represents the adjusted depreciation allowance. No switching is common for this type of situation whenever the salvage value is high. 9.10 Given: I = \$76,000, S = \$6,000, N = 8 years n Dn Bn 1 \$19,000 \$57,000 2 \$14,250 \$42,750 3 \$10,688 \$32,062 4 \$8,016 \$24,046 5 \$6,012 \$18,034 6 \$4,509 \$13,530 7 \$3,765 \$9,765 8 \$3,765 \$6,000 9.11 ⎛1⎞ (a) α = 2.0 ⎜ ⎟ = 0.4 ⎝5⎠ (b) D1 = (0.4)(46, 000) = \$18, 400 (c) B4 = (46, 000)(1 − 0.4) 4 = \$5,962 < \$10, 000, so B4 = \$10, 000.

(d) During year 2006, Oklahoma Oil claimed its depletion deduction in the amount of \$2,040,000 from parcel B. This leaves the book value of \$21,960,000 at the beginning of year 2007. The revised cost per bbl is \$21,960, 000 = \$5.49 per bbl 4, 000, 000 Since no gross income figure is available during year 2007, we may calculate the depletion charge based on unit cost as follows: \$5.49(1, 000, 000) = \$5, 490, 000 9.30 (a) Cost depletion: \$30, 000, 000 Cost per ton = = \$4.6154 per ton 6,500, 000 Depletion cost = \$4.6154(1, 000, 000) = \$4, 615, 400 (b) Percentage depletion: Gross Income \$600,000 Depletion × 10% Computed % depletion \$60,000 Gross Income \$600,000 Expenses \$450,000 Taxable income \$150,000 Contemporary Engineering Economics, Fourth Edition, By Chan S.

Comments: Consider a situation where the extracted coal quality turned out to be very poor. This will result in insignificant market value. In this situation, certainly the use of cost depletion would allow the company to recover much of the loss to the extent of tax law permitting.
