6. (c) 2001 Contemporary Engineering Economics 6 Operating Cash Flow vs. Net Income Net income : Net income is an accounting means of measuring a firm’s profitability based on the matching concept. Costs become expenses as they are matched against revenue. Cash flow : Given the time value of money, it is better to receive cash now than later, because cash can be invested to earn more money. So, it is desirable why cash flows are relevant data to use in project evaluation.

7. (c) 2001 Contemporary Engineering Economics 7 Why Do We Use Cash Flow in Project Evaluation? Company ACompany B Year 1Net income Cash flow $1,000,000 1,000,000 $1,000,000 0 Year 2Net income Cash flow 1,000,000 2,000,000 Example: Both companies (A & B) have the same amount of net income and cash sum over 2 years, but Company A returns $1 million cash yearly, while Company B returns $2 million at the end of 2 nd year. Company A can invest $1 million in year 1, while Company B has nothing to invest during the same period.

10. (c) 2001 Contemporary Engineering Economics 10 U.S. Corporate Tax Rate (2001) Marginal tax rate is defined as the rate applied to the last dollar of income.

15. (c) 2001 Contemporary Engineering Economics 15 Disposal of Depreciable Asset if a MACRS asset is disposed of during the recovery period, Personal property: the half-year convention is applied to depreciation amount for the year of disposal. Real property: the mid-month convention is applied to the month of disposal.

17. (c) 2001 Contemporary Engineering Economics 17 Depreciation recapture Gains = Salvage value – book value = (Salvage value - cost basis) Capital gains + (Cost basis – book value) Ordinary gains Depreciation recapture is taxed as ordinary income.

18. (c) 2001 Contemporary Engineering Economics 18 Capital Gains and Ordinary Gains Cost basis Book valueSalvage value Capital gains Ordinary gains or depreciation recapture Total gains

19. (c) 2001 Contemporary Engineering Economics 19 Gains or Losses on Depreciable Asset Example 11.5: A Drill press: $230,000 Project year: 3 years MACRS:7-year property class Salvage value:$150,000 at the end of Year 3 14.2924.4917.4912.498.92 Full Half Total Dep. = 230,000(0.1429 + 0.2449 + 0.1749/2) = $109,308 Book Value = 230,000 - 109,308 = $120,693 Gains = Salvage Value - Book Value = $150,000 - $120,693 = $29,308 Gains Tax (34%) = 0.34 ($29,308) = $9,965 Net Proceeds from sale = $150,000 - $9,965 = $140,035
