14. www.izmirekonomi.edu.tr Summary The entire cost of replacing a machine cannot be properly charged to any one year’s production; rather, the cost should be spread (or capitalized) over the years in which the machine is in service. The cost charged to operations during a particular year is called depreciation. From an engineering economics point of view, our primary concern is with accounting depreciation; The systematic allocation of an asset’s value over its depreciable life.

15. www.izmirekonomi.edu.tr Accounting depreciation can be broken into two categories: 1. Book depreciation—the method of depreciation used for financial reports and pricing products; 2. Tax depreciation—the method of depreciation used for calculating taxable income and income taxes; it is governed by tax legislation. The four components of information required to calculate depreciation are: (a) cost basis, (b) salvage value, (c) depreciable life, and (4) depreciation method.

16. www.izmirekonomi.edu.tr Because it employs accelerated methods of depreciation and shorter-than-actual depreciable lives, the MACRS (Modified Accelerated Cost Recovery System) gives taxpayers a break: It allows them to take earlier and faster advantage of the tax-deferring benefits of depreciation. The total amount of taxes to pay remains unchanged regardless of depreciation methods adopted. It only changes the timing of the payment. Many firms select straight-line depreciation for book depreciation because of its relative ease of calculation.

17. www.izmirekonomi.edu.tr Given the frequently changing nature of depreciation and tax law, we must use whatever percentages, depreciable lives, and salvage values mandated at the time an asset is acquired.

18. www.izmirekonomi.edu.tr Component of Depreciation Book DepreciationTax depreciation (MACRS) Cost basisBased on the actual cost of the asset, plus all incidental costs such as freight, site preparation, installation, etc. Same as for book depreciation Salvage valueEstimated at the outset of depreciation analysis. If the final book value does not equal the estimated salvage value, we may need to make adjustments in our depreciation calculations. Salvage value is zero for all depreciable assets

19. www.izmirekonomi.edu.tr Component of Depreciation Book DepreciationTax depreciation (MACRS) Depreciable life Firms may select their own estimated useful lives or follow government guidelines for asset depreciation ranges (ADRs) Eight recovery periods– 3,5,7,10,15,20,27.5,or 39 years– have been established; all depreciable assets fall into one of these eight categories. Method of depreciation Firms may select from the following: Straight-line Accelerated methods (declining balance, double declining balance, and sum-of- years’ digits) Units-of-proportion Exact depreciation percentages are mandated by tax legislation but are based largely on DDB and straight-line methods. The SOYD method is rarely used in the U.S. except for some cost analysis in engineering valuation.

20. www.izmirekonomi.edu.tr 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.

21. www.izmirekonomi.edu.tr 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.

22. www.izmirekonomi.edu.tr 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.
