coincides with expectations). The remaining acquisition cost gets
allocated to the periods when the firm uses the asset. We try to get
students to see that a firm cannot observe the pattern by which it uses up
a depreciable asset’s benefits, so any pattern is probably as “accurate” as
any other. After illustrating the calculation of depreciation using various
depreciation methods, we discuss how a firm should choose a depreciation
method for financial reporting. (Exercises 9.19 and 9.20)
5. Develop the skills to compute an impairment loss on long-lived
assets.
The accounting for impairment losses on tangible assets with finite lives
requires a distinction between
(1) Recognition and
(2) Measurement of the loss.
Recognition of Impairment Loss—if Book Value of Assets Exceeds the
Sum of Expected Undiscounted Cash Flows from the Asset.
Measurement of Impairment Loss—equals Book Value of Assets minus
Present Value of Expected Cash Flows from the Asset.
We raise the question: Which of these two approaches best captures
the economic loss that a firm incurs from asset impairment? It is clear
that the second approach, which compares the book value of the assets
to the present value of expected cash flows, best measures the economic
loss. Then ask: Is it possible that a firm would incur an economic loss
but would not recognize the loss under GAAP? The answer is clearly
yes. For this to occur, the undiscounted expected cash flows would
exceed the book value of the asset, but the discounted expected cash
flows would be less than the book value. Finally, ask: Why might the
FASB have imposed a recognition test that uses undiscounted cash
flows? We confess that we see no economic rationale for such a test.
However, in accounting, income is cash in minus cash out, other than
transactions with owners. Thus, if the undiscounted cash flows from an
asset exceed its book value, that asset will not generate an accounting
loss. It can easily generate an economic loss (think invest $1 today to
get back $1.10 in five years, which generates an accounting profit of $5,
even though no sensible person would undertake such a project as it
does not make economic sense). The FASB uses the concept of
recoverability to justify this test. Recoverability means that a firm will
receive cash flows in the future whose sum equals or exceeds the current
book value of the asset, so there is no accounting loss. We use Problem
8.41 to illustrate the recognition and measurement of impairment losses
