Which component is NOT part of accrued depreciation?

Accrued depreciation consists of several components that reflect the loss in value of a property over time. These components include physical depreciation, which accounts for the wear and tear on a property due to physical deterioration; functional obsolescence, which results from changes in design, technology, or consumer preferences that make a property less valuable; and economic obsolescence, which is related to external factors that negatively affect the property’s value, such as changes in the neighborhood or economic conditions.

The component labeled as functional - incurable outside the property boundary specifically refers to a condition that cannot be remedied by actions taken within the property itself. It focuses more on external factors affecting the property that may not be directly addressed by the property owner. This concept is distinct from accrued depreciation, which deals with the internal degradation and value loss directly associated with the property itself.

Therefore, this option stands out from the others, which are all directly related to the depreciation that accumulates either from use or external economic factors impacting the property's worth.
