  Chapter 11 3 Depreciation -Method of Cost Allocation Depreciation  is the accounting process of  allocating the cost of tangible assets to  expense in a systematic and rational manner to  those periods expected to benefit from the use  of the asset. Justification for Depreciation: It matches costs with revenues (the  matching principle). Fluctuation in market values is difficult to be  determined.

  Chapter 11 7 Estimation of Service Lives Service life  ( useful life ): the number of years that  assets is capable of economically providing the  service it was purchased to perform. The estimate of an asset’s service life depends on  both the  economic factors  and the  physical factors   related to its use. Economic factors are characterized by  inadequacy, supersession and obsolescence. Physical factors related to wear and tear, decay,  and casualties that prevent the asset from  performance indefinitely.
