Part 7. Inventories Flashcards
Manufacturing firms report inventory using 3 separate accounts:
- Raw Materials
- Work-in-process
3, Finished goods
Product costs, capitalised in inventories account on balance sheet:
- Purchase cost less trade discounts and rebates.
- Conversion (manufacturing) costs including labor and overhead.
- Other costs necessary to bring inventory to its present location and condition.
Period costs, costs expensed in the period incurred:
- Abnormal waste of materials, labor or overhead.
- Storage costs (unless required as part of production)
- Admin overhead
- Selling costs
Cost flow method
This is used to allocate the inventory cost to the income statement (COGS) and the balance sheet (ending inventory).
Under the IFRS, the permissible methods are:
- specific identification
- first in, first out
- weighted average cost
US GAAP permits the above, plus last in, first out (LIFO), which is not allowed in IFRS.
Specific identification method
This is when each unit sold is matched with the units actual cost.
This is appropriate when inventory items are not interchangeable and commonly used by firms with a small number of costly and easily distinguishable items such as jewellery.
Also appropriate for special orders or projects outside firms normal course of business.
First in, first out (FIFO)
The first item purchased is assumed to be the first item sold.
Advantage:
- the ending inventory is valued based on the most recent purchases, the best approx. of current cost.
- FIFO COGS is based on earliest purchase costs.
- During inflation, COGS will be understated compared to current cost, since earnings will be overstated.
Last in, first out (LIFO)
The item purchased most recently is assumed to be the first item sold.
- During inflation, LIFO COGS will be higher than FIFO COGS, and earnings will be lower.
- Low earnings translate to lower income taxes, which increase cashflow.
- LIFO ending inventory on balance sheet is valued using earliest costs, hence inflation present means LIFO ending inventory is less than current cost.
Weighted average cost
The average cost per unit of inventory is computed by dividing total cost of goods available for sale (beginning inventory + purchases) by total quantity available for sale.
- during inflation or deflation, weighted average cost will produced inventory value between produced by FIFO and LIFO.
Periodic inventory system
Inventory values and COGS are determined at the end of the accounting period, with no detailed records of inventory are maintained, but inventory acquired in period is reported in purchases account.
At the end of the period, purchases are added to the beginning inventory to arrive at COG available for sale.
Calculate COGS, by ending inventory subtracted from goods available for sale.
Perpetual inventory system
The inventory values and COGS are updated continuously, where inventory purchased and sold is recorded directly in inventory when transactions occur, thus the purchase account is not necessary.
periodic vs perpetual
periodic - this system matches the total purchases for the month with the total withdrawals of inventory units for the month.
perpetual - this system matches each unit withdrawn with the immediately preceding purchases.
LIFO vs FIFO during periods of inflation/deflation
Inflation:
- LIFO COGS > FIFO COGS; as last units purchased have higher cost than first units purchased.
- LIFO; the more costly last units purchased assumed to be first units sold (to COGS)
- Higher COGS under LIFO result in lower gross profit and net income compared to FIFO.
- LIFO ending inventory is lower than FIFO, as ending inventory is valued using older lower costs.
Deflation:
- LIFO COGS < LIFO ending inventory; as the most recent lower cost purchases are assumed to be sold first under LIFO, and units in ending inventory assumed to be earliest purchases with higher costs.
Ending inventory
- when prices are rising or falling, FIFO provides more useful measure of ending inventory.
- since FIFO inventory is the most recent purchase, these costs can be viewed as better approx. of current cost thus better approx. of economic value.
- LIFO inventory is based on older costs that may differ significantly from current economic value.
COGS
- changing prices produce significant differences between COGS under LIFO and FIFO.
- LIFO COGS are based on most recent purchases; where prices rising LIFO COGS > FIFO COGS, and opposite when prices fall.
- LIFO produces better approx. of current cost in income statement, as LIFO is based on most recent purchases.
- with changing prices, the WAC method will produce values of COGS and ending inventory between FIFO and LIFO.
Gross profit
- As COGS is subtracted from revenue in calculating gross profit; this is affected by the choice of cost flow method.
- Assuming inflation, higher COGS under LIFO will result in lower gross profit, and all profitability measures will be affected by choice of cost flow method.
