Roy B. Kester, Accounting theory and practice… (1922)
“ It is argued that the plant unit ‘deteriorates’ year by year and that this ‘deterioration’ is the true measure of the ‘depreciation’ in the value of the unit during the intermediate years of its life, and, being a physical condition of the plant, can in no way be measured by the purely financial considerations upon which the reserves for depreciation necessarily must be based. Such a line of reasoning is absolutely faulty. Any attempt to reconcile ‘deterioration’ with ‘depreciation’ at any intermediate period in the life of the plant of an undertaking, is not only unnecessary but futile. ”
