6. (c) 2001 Contemporary Engineering Economics 6 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. The actual timing of cash inflows and outflows are ignored. 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.

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.

24. (c) 2001 Contemporary Engineering Economics 24 Summary Explicit consideration of taxes is a necessary aspect of any complete economic study of an investment project. Once we understand that depreciation has a significant influence on the income and cash position of a firm, we will be able to appreciate fully the importance of utilizing depreciation as a means to maximize the value both of engineering projects and of the organization as a whole.

25. (c) 2001 Contemporary Engineering Economics 25 For corporations, the U.S. tax system has the following characteristics: 1. Tax rates are progressive: The more you earn, the more you pay. 2. Tax rates increase in stair-step fashion: four brackets for corporations and two additional surtax brackets, giving a total of six brackets. 3. Allowable exemptions and deductions may reduce the overall tax assessment.

26. (c) 2001 Contemporary Engineering Economics 26 Marginal tax rate is the rate applied to the last dollar of income earned; Average (effective) tax rate is the ratio of income tax paid to net income; and Incremental tax rate is the average rate applied to the incremental income generated by a new investment project. Capital gains are currently taxed as ordinary income, and the maximum rate is capped at 35%. Capital losses are deducted from capital gains; net remaining losses may be carried backward and forward for consideration in years other than the current tax year.

27. (c) 2001 Contemporary Engineering Economics 27 An investment tax credit is a direct reduction of income taxes payable, arising from the acquisition of depreciable assets. Government uses the investment tax credit to stimulate investments in specific assets or in specific industries.
