Inventories
Why is Inventory Control
Important?
Inventory is a significant asset and for many companies the largest asset.
Inventory is central to the main activity of merchandising and manufacturing companies.
Mistakes in determining inventory cost can cause critical errors in financial statements.
Inventory must be protected from external risks ( such as fire and theft) and internal fraud by employees.

FIFO ( Cost Accounting)
• FIFO is most useable technique of valuation of material issue in manufacturing and trading industries.
• It means First in, First Out.
• We will send that material for production first which we bought first.
• We also record the cost of issue on this basis.
• Closing stock's value in store will be the purchase value of material which we purchased at the end.
• This system of valuation of cost is very useful where there is the trend of decreasing prices, because we will charge high cost to the units which we bought earlier to new.
• But this method is not useful in the trend of increasing prices.
Merits of FIFO Method
• This method is very logical because material should be issued first which we bought first.
• Because we issue the material at its purchase price, so closing stock can be calculated correctly.
• Closing stock's cost automatically shows the market price.
Demerits of FIFO Method
• In case, there is fluctuation in prices, we can not calculate correct cost of material issued.
• We also can not compare on job's cost with other job's cost in case prices are fluctuating.
• This is not good method in inflation.

Because the purchase price of $21 is
different than the cost of the previous 3

What is LIFO
• In this method of valuation of inventory, we calculate the inventory issue cost by reverse order.
• It means that we charge old quantities price first for issue of material and then new prices will be charged.
• It is just opposite of FIFO. It is most suitable in inflation of prices.
• In other words, LIFO is last-in, first-out, meaning that the most recently purchased items are recorded as issued for production first from store.
• If LIFO is used for calculating the cost of goods sold and closing stock, then it will calculated for calculating correct gross and net profit.
• At that time, we take last (latest) purchase price for sold material first time.
