Answer:
Is a known obligation of an uncertain amount that can be reasonably estimated
Step-by-step explanation:
A liability is a present obligation of an entity as a result of a past event, for which economic resources are expected to flow out of the entity.
As such, an estimated liability is a present and known obligation of an entity. The amount of such liability is uncertain but can be reliably estimated.
A good example of such liability is accrued expenses.
