Since you are applying a full year depreciation in year 1, that would imply the asset was booked to the balance sheet on the first day of the first month in that year. A 5-year life for the asset means it should be fully depreciated on Dec.31 of the 4th year, yet you show a full year depreciation in year 5.
It would be more correct to assume the asset was booked at the mid-point of year 1, and then you would have 1/2 year's depreciation in both the first and last year of the asset's life -- across a total of 6 years.
