Non-monetary assets are possessions that a firm has but whose financial value cannot be determined with certainty. These are possessions whose monetary value is subject to wide fluctuations over time. A business could need to replace its non-financial assets if they deteriorate or become outdated. Factory-built tools and vehicles are one illustration of this. In general, non-monetary assets are those that are shown as such on the balance sheet but which cannot be quickly or easily converted into cash or cash equivalents.
