aThese rates are determined by applying the 200% DB method (with switchover to the SL method) to the recovery period with the half-year convention applied to the first and last years. Rates for each period must sum to 1.0000.
bThese rates are determined with the 150% DB method instead of the 200% DB method (with switchover to the SL method) and are rounded off to four decimal places.
(a) The depreciation deduction, or cost-recovery allowance, that is allowable in year four (d_{4}) is 0.1152 ($100,000) = $11,520.
(b) The BV at the end of year four (BV_{4}) is the cost basis less depreciation charges in years one through four:
BV_{4} = $100,000 − $100,000(0.20 + 0.32 + 0.192 + 0.1152)
= $17,280.
(c) Accumulated depreciation through year three, d^{*}_{3}, is the sum of depreciation amounts in years one through three:
d^{*}_{3}= d_{1}+d_{2}+d_{3}
= $100,000(0.20 + 0.32 + 0.192)
= $71,200.
(d) The depreciation deduction in year five can only be (0.5)(0.1152)($100,000) = $5,760 when the equipment is disposed of prior to year six. Thus, the BV at the end of year five is BV_{4} − $5,760 = $11,520.
