During the third year, the company estimates that the remaining useful life is eight
years (instead of three) and that the residual value is $8,000 (instead of $10,000). The
depreciation expense for each of the remaining eight years is $10,000, computed as
follows:
Book value (undepreciated cost), end of second year $88,000
Less revised estimated residual value 8,000
Revised remaining depreciable cost $80,000
Revised annual depreciation expense ($80,000 ÷ 8 years) $10,000
Exhibit 7 shows the book value of the asset over its original and revised lives.
Notice that the book value declines at a slower rate beginning at the end of year 2 and
continuing until it reaches the residual value of $8,000 at the end of year 10, which is
the revised end of the asset’s useful life.
A change in estimate should be disclosed in the notes to the financial statements.
An example of such a disclosure is shown for St. Paul Companiesas follows:
Acceleration of Software Depreciation....The resulting strategy to standardize tech-
nology throughout...and maintain one data center in St. Paul, Minnesota, resulted
in the identification of duplicate software applications. As a result, the estimated use-
ful life for that software was shortened, resulting in an additional charge to earnings.
FIXED ASSET DISPOSALS
Fixed assets that are no longer useful may be discarded, sold, or exchanged for other
fixed assets.^4 Often, such transactions will give rise to gains and losses upon disposal.
The details of the entry to record a disposal will vary. In all cases, however, the book
410 Chapter 9 Fixed Assets and Intangible Assets
Q.An asset with an origi-
nal cost of $80,000 and
a residual value of
$12,000 was estimated to
have an eight-year life.
After three years, the asset
is estimated to have a re-
maining life of 10 years,
with no change in residual
value. What is the revised
depreciation expense for
the fourth year?
A.$4,250. The deprecia-
tion expense per year for
the first three years is
$8,500 per year
[($80,000$12,000) ÷
8]. The book value at the
end of the third year is
$54,500 [$80,000
(3$8,500)]. The re-
maining book value less
the residual value divided
by the remaining life is
[($54,500$12,000) ÷
10].
