## Scope of AS 19
AS 19 applies to all leases except the following three categories:
### Exclusions from AS 19
| Category | Examples |
|---|---|
| Natural resource exploration/use leases | Oil, gas, metals, minerals |
| Licensing agreements for intangibles | Motion picture films, video recordings, plays, manuscripts, patents, copyright |
| Lease agreements to use land | Any land lease |
> Why these exclusions? These arrangements involve specialized assets, intangible rights, or natural resources governed by other laws/standards. They have unique risk-reward profiles not covered well by a general lease standard.
### Practical Test
Whenever you see a lease question — first confirm the asset type. If it is machinery, equipment, vehicles, buildings (other than land), aircraft, ships — AS 19 applies. If it is oil fields, copyrights, or land — AS 19 does not apply.
