👉 Impoundable is a concept used in the context of law and economics to describe certain types of assets that cannot be easily liquidated or sold on the open market. These assets are often considered "immaterial" or "nonmarketable," as they do not have an immediate economic value or can only be traded for a relatively small amount of money. Impoundables typically fall into one of two categories: non-perpetual (i.e., permanent) and perpetual (i.e., temporary).
