If you're using depreciation conventions and you modify the last depreciation run date for an asset, which skips some depreciations, the depreciation for the last year might be greater or less than is expected. The depreciation is adjusted by the number of depreciation periods affected by the modification of the last depreciation run date.

For example, if you are using the half year depreciation convention over three years, depreciation normally occurs over 3 1/2 years. If you change the last depreciation run date during the 3 1/2 years, the last year of depreciation moves out the number of periods affected. If you move the date by three months, the last year will have nine months worth of depreciation, when normally there would be six months worth of depreciation. You can choose from the following depreciation conventions.
