Chapter 6 INVENTORIES
Inventory and the matching principle:
Inventory is an asset when purchased
Becomes expense when it is sold
(cost of goods sold)
INVENTORY COST FLOW METHODS
Cost of inventory must be allocated between units sold during period (expense) and
units left on hand at end of period (asset)
Problem:
Counting the number of items on hand at the end of the period is relatively easy.
Sometimes, though, the same item purchased at different times will have a different cost.
So how do we assign a dollar cost to the units left in inventory and a dollar cost to the units
sold during the period?
Ex: identical light bulbs at the beginning of the year and at the end of the year cost a
diff. amt.
Solution: inventory cost flow methods
1. specific ID method –
each item is uniquely identifiable
2. weighted average method
Assumes that all unit available for sale have the same weighted average cost
3. FIFO –
“First i, first out” e: ilk o the raks i the groer store before they expire)
It assumes that items are sold in the same order as they were purchased.
4. LIFO –
“Last i, first out” e: takig soethig off the top of the pile
It assumes items are sold in reverse of the order purchased
NOTE: The cost flow method chosen does not hae to ath the opa’s physical flow of
goods.
Consistency is important!
The company must use the same method year after year.

Example: Inventory cost flow (valuation) methods
Units Purchase price Total purchase
per unit
Beginning inventory 10 $ 5 $ 50
Purchases:
Oct 2 8 6 48
Oct 5 5 9 45
Oct 21 7 10 70
$213
Ending inventory 12
Determine the dollar amount that will be assigned to the ending inventory and cost of
goods sold using:
a. weighted average method
b. FIFO
c. LIFO
