Divisional performance and depreciation
ROI or RI: the problem with depreciation
4 Divisional performance and depreciation
4.1 ROI or RI: the problem with depreciation
If straight-line depreciation is used and capital employed is based on carrying
values (net book values) the annual ROI and residual income will increase over time
if:
annual profits are constant, and
assets are not replaced, and existing assets remain in use as they get older.
In the early years of an investment, the ROI or residual income may be very low. If a
divisional manager is concerned about the effect that this would have on the
division’s ROI or residual income for the next year or two, the manager may refuse
to invest in the project. This is because performance in the next year or so might be
much worse, even though the project might be expected to earn a high return over
its full economic life.
The tendency for ROI and residual income to increase over time if assets are not
replaced means that divisional managers may prefer to keep old and ageing assets
in operation as long as possible – even though it might be preferable in the longer
term to replace the assets sooner.
Example
A company has just opened a new division that will operate as an investment
centre. The following estimates of future performance have been made.
The division requires an investment of $5 million. This consists entirely of new non-
current assets. Non-current assets will be depreciated at the rate of 25% of cost each
year, and there will be no residual value after four years.
Sales revenue in the first year will be $10.8 million, but in subsequent years will
change as follows:
(1)
There will be no change in selling prices in Year 2, but prices will be reduced
by 5% in Year 3 and by a further 5% in Year 4.
(2)
Sales volume will increase by 10% in Year 2 and a further 10% in Year 3, but
sales volume in Year 4 will be the same as in Year 3.
