Roy B. Kester, Accounting theory and practice… (1922)
“ For purposes of management, which must control all the phases of business activity, a balance sheet is insufficient. A review of the factors producing results up to a given time must be had. Accordingly, the accounting department must supply not only information as to the present state of the assets and liabilities, but also information which indicates how the changes in assets and liabilities since the last fiscal period were brought about—what volume of transactions occurred, what expenditures of assets and energy were necessary to accomplish the results attained. ”
