Another widely used approach, called the half-year convention, is to record one-half year's depreciation on all assets acquired during the year. This approach is base on the assumption that the actual purchase dates will average out to approximately midyear. The half-year convention is widely used for assets such as office equipment, automobiles, and machinery. To complete the depreciation process for an asset by the half-year convention, a one-half-year's depreciation is also taken in the last year of the asset's life.
