This document discusses the declining balance method for calculating depreciation. It explains that the declining balance method results in higher depreciation expenses in the early years of an asset's life and lower expenses in later years. The formula for calculating depreciation under this method is presented as Depreciation per annum = (Net Book Value - Residual Value) x Rate of depreciation %. An example is provided to demonstrate how depreciation expenses would decrease each year over a 3 year asset life. Finally, the advantages and disadvantages of different depreciation methods are briefly compared.
