We feel that increases within the replacement price of operating assets (e.g., greater projected money outflows to replace equipment) are not gains, realized or not. Whereas current-cost-based earnings measures a firm’s approximate disposable wealth, modifications in the current price of inventory, plant, equipment, along with other operating assets are revaluations of owners’ equity, which can be the portion of earnings that the business should maintain to preserve its physical capital (or productive capacity). Assets held for speculation, like vacant land or marketable securities, don't have to be replaced to sustain productive capacity. Hence, if current-cost adjustments include these items, increases or decreases in their current-cost (value) equivalents (up to their realizable values) really should be stated directly in revenue.
