1. What are the three distinct definitions of depreciation?

They are: decline in market value of an asset; decline in value of an asset to its owner; systematic allocation of the cost of an asset over its depreciable life. (p. 333)

2. Explain briefly why depreciation is a non-cash expense.

It is mainly because the firm has already paid for the asset up front, and depreciation is simply a way to claim the wearing out of the asset over time. (p. 334)

3. Explain briefly why depreciation should be considered in after-tax economic analysis.

It is mainly because depreciation deductions reduce the taxable income of a business, which reduces the amount of tax paid, and taxes are cash flows. (p. 334)

4. What are the four general depreciation methods?

They are: straight-line depreciation, sum-of-year’s digit’s depreciation, declining-balance depreciation, and unit-of-production depreciation. (pp. 337-342)
