Roy B. Kester, Accounting theory and practice… (1922)
“ Stock-in-trade, as the term is usually understood, comprises all commodities purchased for resale. Thus, assets, which in one concern belong to the fixed asset group, may be the stock-in-trade of other concerns. In stating the principles of valuation for these assets, it is definitely to be understood that they apply only to such as are used as stock-in-trade, and not to the same items when used as fixed assets. Oftentimes the process of manufacture intervenes between the purchase of a commodity and its sale. ”
