PROPRIETARY THEORY
PROPRIETARY THEORY is where no fundamental distinction is drawn between a legal entity and its owners, i.e. the entity does not exist separately from the owners for accounting purposes. The primary focus is to report information useful to the owners, and therefore the financial statements are prepared from their perspective.
ENTITY THEORY
ENTITY THEORY is where a legal entity is regarded as having a separate existence from the owners. The financial statements are prepared from the perspective of the entity, not its owners.
