ceiling

A term used in the lower of cost or market (LCM) that serves as a constraint for the market value. In the LCM for inventory, the ceiling is the net realizable value (NRV). This means that if the replacement cost of an inventory item is greater than the NRV, the NRV becomes the market amount that will be compared with the item's cost for valuing inventory under LCM.
