102.05 - Statewide Accounting Policy - Depreciation
The straight-line and units of output methods of depreciation, with an assumed salvage value of zero, are the recommended methods of depreciation. It is also recommended that depreciation for partial periods be computed using either the half-year convention or on the basis of the nearest full month. Straight-line is a time-based method used when the service life of the asset is affected primarily by the passage of time. Units of output should be used when the service life of the asset is affected primarily by the amount the asset is used. See table below for depreciation method guidelines.
