ethod ("RIM"). Under RIM, the valuation of inventory at cost and the resulting gross margins are calculated by applying a cost-to-retail ratio to the retail value of inventory. RIM is an averaging method that has been widely used in the retail industry due to its practicality. The use of RIM will result in inventory being valued at the lower of cost or market since permanent markdowns are taken as a reduction of the retail value of inventories. A reserve is recorded if the future estimated selling price is less than cost.
