The first question was the nature of the asset involved because the radio spectrum is not explicitly included in the 1993 SNA classification of assets. The ISWGNA considered it fits best into the category of tangible non-produced assets, which are described as covering "mainly land and subsoil assets" (paragraph 7.87).
L'ISWGNA a jugé bon de le placer dans la catégorie des actifs corporels non produits, qui sont décrits comme englobant "principalement les terrains et les gisements" (paragraphe 7.87).
