A system of accounting based principally on replacement costs, and measuring profit as the increase in physical capital,
was used in the UK for some years (called current cost accounting).
The main accounting system has always been, and will continue to be, historical cost accounting. However, current cost
accounting was developed as a possible solution to certain problems which arise in periods of rising prices. Theoretical
and practical problems in the current cost accounting system led to its withdrawal in the UK.
Attempts to solve the problems of inflation have a long history in the UK and abroad. One step common in practice is to
prepare modified historical cost accounts. This means that up-to-date valuations are included in the historical cost
statement of financial position for some or all of a company's non-current assets, without any other adjustments being
made. No attempt is made to tackle the difficulties of profit measurement.
For the foreseeable future, historical cost accounting is likely to be the most important system in the UK, despite its
inability to reflect the effects of inflation.
There are a number of reasons why this is so.
(a) It is easy and cheap. Other methods tend to be far more complicated and onerous to use, particularly for small
businesses. Also, there is no agreement on an alternative.
(b) The fact that non-current asset revaluation is permitted or encouraged means that there is less likelihood of a
serious understatement of actual value distorting the statement of financial position valuation of the business.
(c) It is easy to understand and users are aware of its limitations, so make appropriate allowances. Alternative
methods generally involve much more complex concepts.
(d) The figures are easy to obtain and are objective and readily verifiable, being tied to actual transactions. Other
methods depend more on subjective valuations.
It is important to note that, legally, a business does not have to account for inflation.
Question
Inflation
In a period when prices are rising, the profit shown under the historical cost convention will differ from that shown under
the current cost convention. In the case of a retail trading company, which of the two profit figures will be higher?
Answer
The profit shown under the historical cost convention will be higher. This is because the value of the resources used is
their cost at the time they were purchased. Under the current cost convention, the value of these resources is their cost
at the (later) time when they were replaced. Given that prices are rising, this cost will be higher and so reported profits
will be less.
