When an asset is disposed part way through an accounting period, the Depreciation and Amortization Calculation Worksheets calculate the number of days incorrectly. The reports list the number of days including and after the date of disposal, not the number of days through the date of disposal.
For example, if disposal takes place on August 31, the 243rd day of a 365-day year, the reports calculate depreciation or amortization for 123 days. Correction of this bug requires a decision as to whether the day of disposal should be included as a day of depreciation/amortization. In other words, if an asset is disposed on the last day of the year, should a full year’s depreciation/amortization be calculated. I believe yes, to be consistent with the general behavior of the program that figures represent performance or position at the end of the day. Thus, in the example above, the report should calculate 243 days, not 365 - 123 = 242 days.
