Definition: Economic appearance of non-produced assets
Economic appearance of non-financial non-produced assets represents the increase in the volume of this kind of assets that is not the result of production.
a) gross increases in the level of exploitable subsoil resources: proven reserves of coal, oil, natural gas, metallic minerals or non-metallic minerals that are economically exploitable. This also covers the increase in reserves for which exploitation becomes economic as a result of technological progress or relative price changes;
b) transfers of other natural assets to economic activity: naturally occurring entities that change status to qualify as economic assets, economic assets being entities over which ownership rights are enforced by institutional units and from which economic benefits may be derived by their owners (e.g. exploitation of virgin forests, transfer of land from a wild or waste state to land that can be put to economic use, land reclamation);
c) quality changes in non-produced assets due to changes in economic uses. Changes in quality are treated as changes in volume. The quality changes recorded here occur as the counterpart of the changes in economic use that are shown as changes in classification - e.g. from cultivated land to land underlying buildings;
d) appearance of intangible non-produced assets. Intangible non-financial non-produced assets arise when entities are patented or transferable contracts are written. Also when enterprises are sold at prices that exceed their own funds, the excess of purchase price over own funds is the asset "purchased goodwill". Goodwill not evidenced by a sale/purchase is not considered as an economic asset.
