Policies as to Repairs
Without doubt the most important single factor in the determination
of the depreciation rate is the normal policy as to repairs and
maintenance. Physical deterioration is constantly at work. If this
is counteracted by a liberal maintenance policy, not only is more
efficient service secured but a longer service life is thereby insured.
As soon as repairs are needed, although the efficiency of the asset
may not be immediately impaired, the _rate_ of deterioration is much
accelerated unless the condition is corrected. Deterioration takes
place day by day, but repairs obviously cannot be made at such short
intervals—both because of the difficulty of detection and also because
such a policy would not be economically practical. Every concern must
consider its own peculiar problems and determine from these what shall
constitute its normal repairs policy, and so far as possible this
should be adhered to. The charges for repairs are bound to be of a more
or less irregular character. Their handling is discussed on page 147.
Regardless of what the established policy as to repairs may be,
conditions are sure to arise which make strict adherence to it
impossible. There may occasionally be lack of funds at the time
repairs are customarily attended to; it may be impossible to get the
expert labor needed or the parts to replace worn-out units; or, and of
oftenest occurrence, the need of repairs may coincide with a period of
intense activity when the plant is being worked to its limit and in
consequence there is no opportunity for making repairs. It is clear
that rates based on one shift and the normal use of equipment during
eight hours would be inadequate for three shifts and twenty-four hours
of use; for in addition to a threefold intensity of operation this
makes impossible adherence to the normal repairs policy based on an
eight-hour schedule.
Depreciation Rate an Engineering Problem
From the above discussion it is apparent that the determination of
rates is essentially an engineering problem. The accountant, however,
needs a knowledge of the fundamental considerations and requirements
of fixing depreciation rates and an appreciation of the difficulties
of the problem. As Henry Floy[30] says: “What engineer is able to
foretell the misuse and neglect or care and high degree of maintenance
that any given apparatus or ... property as a whole will receive, even
during the next five or ten years, with vicissitudes of climate, load
conditions, changes of management, and requirements of the public?”
On the other hand, in the opinion of another prominent engineer,
“Consideration of these matters (misuse, neglect, etc.) may eventually
form the basis for a systematic appraisal of the probabilities of life,
or average of the risks, which would provide a method for the insurance
of the life of machinery.”
[30] In “Value for Rate-Making.”
The author does not attempt to discuss the relative merits of the
two contentions other than to point out the fact that engineers are
not discouraged in spite of the many contingencies and uncertainties
inherent in the problem. They are constantly gathering data from which
conclusions as to rates are being formed, the use of which is being
compelled by regulating bodies. It is possible that the problem will
ultimately be worked out on some kind of an insurance basis.
Attitude of Regulatory Bodies
At the present time the attitude of most regulatory bodies—public
service boards, federal commissions, and tax officials—is well
expressed by a regulation of the Public Utility Commission of New
Jersey which says that, “Until otherwise prescribed, the amount
estimated to be necessary to cover such wear and tear and obsolescence
and inadequacy as have accrued during any month shall be based on a
rule to be determined by the accounting corporation; such rule may be
derived from a consideration of the said corporation’s history and
experience. A general statement of the rule in use by each company,
together with the general information upon which it is based, is to be
filed with the Board of Public Utility Commissioners.” The trend at the
present time is towards a more thorough supervision of depreciation
rates on the part of many public service boards, and the future will
undoubtedly see interesting developments.
Methods of Handling Repairs
Three distinct practices are met with in handling repairs and
renewals on the books. The most general method is dictated by ease of
application and rests on the theory of averages, viz.: that the amount
of repairs annually recurring for depreciating equipment in all degrees
of deterioration and all stages of decay and age is a fairly constant
figure which secures an equitable distribution over the product of the
different years. The larger the plant and the greater the variety of
the equipment used, the more nearly does this work out as expected.
Further consideration will be given to this point in the discussion in
