2. The percentages in MACRS GDS for personal property were calculated based on the following principles: The 3-, 5-, 7- and 10-year classes use 200% and the 15- and 20-year classes use 150% declining balance depreciation. All classes convert to straight-line depreciation in the optimal year, shown with the asterisk (*). A half-year of depreciation is allowed in the first and last recovery years. Salvage value are assumed to be zero for all assets. If the 15- and 20-year classes also use 200% declining balance depreciation, what would be the depreciation schedule for the 15- and 20-year classes? (hint: use excel)
