1. In the SNA, changes in assets that are not economic transactions and are thus recorded outside the production (supply and use) accounts. Include changes in non-produced natural assets such as discoveries, natural growth, depletion and degradation of natural assets, and natural disasters or war that may affect produced and non-produced assets; 2. In the SEEA, depletion and degradation of natural assets are shifted from other volume changes as cost into the production accounts and as capital consumption into the accumulation/asset accounts. All other changes in asset volume remain as other volume changes in the asset accounts.
