*K Estimating Inventories—Gross Profit and Retail Inventory Methods.
1. Two circumstances explain why companies sometimes estimate inventories:
a. A casualty such as a fire, flood, or earthquake may make it impossible
to take a physical inventory.
b. Managers may want monthly or quarterly financial statements, but
a physical inventory is taken only annually.
2. There are two widely used methods of estimating inventories:
a. The gross profit method is used in preparing monthly financial state-
ments under a periodic system.
(1) Step 1: Net sales less estimated gross profit equals estimated
cost of goods sold.
(2) Step 2: Cost of goods available for sale less estimated cost of
goods sold (from Step 1) equals the estimated cost of ending
inventory.
(3) The gross profit method is based on the assumption that the
gross profit rate will remain constant.
(4) Companies should not use the gross profit method to prepare
financial statements at the end of the year.
b. When a store has many different types of merchandise at low unit
costs, the retail inventory method is often used.
(1) Under the retail inventory method, a company’s records must show
both the cost and retail value of the goods available for sale.
(2) Step 1: Goods available for sale at retail less net sales equals
ending inventory at retail.
