Answer:
a. Using the straight-line method, compute the annual depreciation that would have been charged from 1994 through 2003.
depreciable value = $2,320,000 - $68,800 = $2,251,200
annual depreciation expense = $2,251,200 / 40 years = $56,280
b. Compute the annual depreciation that would have been charged from 2004 through 2022.
annual depreciation expense = $56,280 + [($580,000 - $23,200) / 30 years] = $74,840
c. Prepare the entry, if necessary, to adjust the account balances because of the revision of the estimated.
no journal entry required, the carrying value is the same, only the annual depreciation expense will change
d. Compute the annual depreciation to be charged, beginning with 2022.
accumulated depreciation until 2022 = (10 years x $56,280) + (18 x $74,840) = $1,909,920
carrying value = ($2,320,000 + $580,000) - $1,909,920 = $2,900,000 - $1,909,920 = $990,080
depreciable value = $990,080 - $68,800 - $23,200 = $898,080
annual depreciation = $898,080 / 32 years = $28,065
