Costs included in Inventory (Manufacturing Inventory)
a. Raw Materials - recorded at amount paid to acquire
b. Work in Process - MATERIALS, LABOR + OVERHEAD costs
c. Finished Goods - ready for sale
Costs included in Inventory (Merchandise inventory)
Finished goods ready for sale
Costs Included in Inventory (Quantity Issues)
a. Goods in Transit - FOB Shipping + FOB destination
b. Consignment Stock - owner of inventory reports it, not consignment store
c. Returns - actual and estimated inventory returns
Inventory Flow (Beginning to Ending or COGS)
Beginning Inventory
+ Purchases
= Goods Available for Sale
- COGS
= Ending Inventory
OR
Goods Available for Sale
-Ending Inventory
= COGS
Perpetual Inventory Systems
Accounts for how of inventory (purchases & sales) in REAL TIME
Perpetual Inventory (Journal Entry)
Purchase:
Dr. Inventory
Cr. Accounts Payable
Sale:
Dr. COGS
Cr. Inventory
Periodic Inventory Systems
Account for purchases in REAL TIME and calculates COGS at the END of the period
Periodic Inventory Systems (Journal Entry)
Purchase:
Dr. Purchases
Cr. Accounts Payable
Sale: No Entry for COGS or Inventory (Dr. A/P and Cr. Sales only)
End of Period: use Inventory Flow Equation and a physical count of inventory on hand to solve for COGS and make a journal entry to adjust ending inventory and COGS
FIFO (First In First Out)
Oldest items are sold first, newest items remain in ending inventory
LIFO (Last In First Out)
Newest items are sold first and oldest items remain in ending inventory
Average Cost
Calculate an average cost of Good Available for Sale
Average Cost = Goods Available for Sale $ / Goods Available for Sale #
*Average Cost x # of Units Sold = COGS
*Average Cost x # of Units remaining = Ending Inventory
(FIFO) Difference between FIFO and LIFO in terms of the accounting impact and why someone would use one versus the other ***
FIFO = Provides HIGHEST INVENTORY and LOWEST COGS leading to:
–Higher profits due to low COGS
–Stronger balance sheet as ending inventory reflects most recent, higher costs
–People choose LIFO because it shows higher assets and higher profit even though they pay more taxes
(LIFO) Difference between FIFO and LIFO in terms of the accounting impact and why someone would use one versus the other ***
LIFO = Provides LOWEST INVENTORY and HIGHEST COGS leading to:
–Decrease in taxable income, have to pay less taxes
–Some argue more accurate and current costs and revenues are reported
–Good for industries where inventory costs rise, like retail, automotive etc.
How to Adjust from FIFO to LIFO (LIFO Reserve)*
FIFO Inventory
-LIFO Inventory
= LIFO Reserve (contra account)
Important for financial statement readers to convert back to FIFO to compare to other companies
LIFO Reserve for COGS*
FIFO COGS
+/- Change in LIFO Reserve
= LIFO COGS
Journal Entry:
Dr./Cr. LIFO Reserve
Dr./Cr. COGS
LIFO Liquidation
If purchases are LESS than sales, older inventory items are “sold” and erodes tax benefits of LIFO
–If purchases are LESS than sales, eats away at older layers of inventory
–If purchases are GREATER than sales, add a layer of inventory from current year purchases
Why pooled LIFO methods (like Dollar-Value LIFO) are preferable over unit LIFO (regular LIFO)
Pooled LIFO methods reduce the risk of LIFO Liquidation!
Dollar-Value LIFO***
Using BASE-YEAR VALUE of inventory (value on day started using LIFO) and CURRENT YEAR VALUE of same inventory
Dollar-Value LIFO (Price Index Equation)
Price Index = Current Year Value / Base-Year Value
Price Index is how much prices have changed since Base-Year
Price Index is always 1 on Base-Year and Unit cost at Base-Year is always the same
PROBLEM 1: DOLLAR-VALUE LIFO***
PRACTICE
Lower of Cost or Net Realizable Value (LCNRV) (equations)
Lower of Cost = FIFO/LIFO/Average Cost
Net Realizable Value = Selling Price - Cost to Complete or Sell
Lower of Cost or Net Realizable Value (LCNRV)
If Net Realizable Value FALLS BELOW Cost, must write Inventory down to the lower value.
