Repeat steps
@
and
(f)
to
obtain each succeeding year's deprecia-
tion and remaining book value until the book value is
equal
to or
less than the
salvage
value. In the latter case, the previous book
value is
reduced
by
the
salvage value to obtain the final year's
depreciation.
Sample Case: A fleet car has a
value
of $2500, a salvage value of $400
which is not deducted from the present value, and a life expectancy of
six years. If you are using the double declining balance method, what
is the amount of depreciation and book value for years 1-4?

Note that an asset cannot be depreciated beyond salvage value-there-
fore, depreciation

$400.
Discounted Cash Flow Analysis
For capital budgeting purposes, it is often required that a discounted
cash flow
analysis
be performed to
see
if a particular
investment
is
at
least
as
profitable
as some
norm (often called the
cost
of capital or dis-
count
rate).
This
calculation finds the present values of all the future cash flows
(appropriately discounted by cost of capital) less original investment.
