Objective
A primary issue in accounting for inventories is the determination of the value at which inventories are carried in the financial statements until the related revenues are recognised. This Statement deals with the determination of such value, including the ascertainment of cost of inventories and any write-down thereof to net realisable value.
Scope
1. This Statement should be applied in
accounting for inventories other than:
(a)
work in progress arising under
construction contracts, including directly related service contracts (see
Accounting Standard (AS) 7, Accounting for Construction Contracts);
(b)
work in progress arising in the
ordinary course of business of service providers;
(c)
shares, debentures and other financial
instruments held as stock-in-trade; and
(d)
producers' inventories of livestock,
agricultural and forest products, and mineral oils, ores and gases to the
extent that they are measured at net realisable value in accordance with well
established practices in those industries.
2.
The inventories referred to in paragraph 1(d) are measured at net realisable value at certain stages of production. This occurs, for example, when agricultural crops have been harvested or mineral oils, ores and gases have been extracted and sale is assured under a forward contract or a government guarantee, or when a homogenous market exists and there is a negligible risk of failure to sell. These inventories are excluded from the scope of this Statement.

Definitions
3. The following terms are used in this Statement with the meanings specified:
Inventories are assets:
(a)
held for sale in the ordinary course
of business;
(b)
in the process of production for such
sale; or
(c)
in the form of materials or supplies
to be consumed in the production process or in the rendering of services.
Net
realisable value
is the estimated selling price in the
ordinary course of business less the estimated costs of completion and the
estimated costs necessary to make the sale.
4. Inventories encompass goods purchased and
held for resale, for example, merchandise purchased by a retailer and held for
resale, computer software held for resale, or land and other property held for
resale. Inventories also encompass finished goods produced, or work in progress
being produced, by the enterprise and include materials, maintenance supplies,
consumables and loose tools awaiting use in the production process. Inventories
do not include machinery spares which can be used only in connection with an
item of fixed asset and whose use is expected to be irregular; such machinery
spares are accounted for in accordance with Accounting Standard (AS) 10,Accounting for Fixed Assets.
Measurement of Inventories
5. Inventories
should be valued at the lower of cost and net realisable value.
Cost of Inventories
6. The cost of inventories should comprise all
costs of purchase, costs of conversion and other costs incurred in bringing the
inventories to their present location and condition.
Costs of Purchase
7. The costs of purchase consist of the
purchase price including duties and taxes (other than those subsequently
recoverable by the enterprise from the taxing authorities), freight inwards and
other expenditure directly attributable to the acquisition. Trade discounts,
rebates, duty drawbacks and other similar items are deducted in determining the
costs of purchase.
Costs of Conversion
8. The costs of conversion of inventories
include costs directly related to the units of production, such as direct
labour. They also include a systematic allocation of fixed and variable
production overheads that are incurred in converting materials into finished
goods. Fixed production overheads are those indirect costs of production that
remain relatively constant regardless of the volume of production, such as
depreciation and maintenance of factory buildings and the cost of factory
management and administration. Variable production overheads are those indirect
costs of production that vary directly, or nearly directly, with the volume of
production, such as indirect materials and indirect labour.
9. The allocation of fixed production overheads
for the purpose of their inclusion in the costs of conversion is based on the
normal capacity of the production facilities. Normal capacity is the production
expected to be achieved on an average over a number of periods or seasons under
normal circumstances, taking into account the loss of capacity resulting from
planned maintenance. The actual level of production may be used if it
approximates normal capacity. The amount of fixed production overheads
allocated to each unit of production is not increased as a consequence of low
production or idle plant. Unallocated overheads are recognised as an expense in
the period in which they are incurred. In periods of abnormally high
production, the amount of fixed production overheads allocated to each unit of
production is decreased so that inventories are not measured above cost.
Variable production overheads are assigned to each unit of production on the
basis of the actual use of the production facilities.
10. A production process may result in more than
one product being produced simultaneously. This is the case, for example, when
joint products are produced or when there is a main product and a by-product.
When the costs of conversion of each product are not separately identifiable,
they are allocated between the products on a rational and consistent basis. The
allocation may be based, for example, on the relative sales value of each
product either at the stage in the production process when the products become
separately identifiable, or at the completion of production. Most by-products
as well as scrap or waste materials, by their nature, are immaterial. When this
is the case, they are often measured at net realisable value and this value is
deducted from the cost of the main product. As a result, the carrying amount of
the main product is not materially different from its cost.
Other Costs
11. Other costs are included in the cost of
inventories only to the extent that they are incurred in bringing the
inventories to their present location and condition. For example, it may be
appropriate to include overheads other than production overheads or the costs
of designing products for specific customers in the cost of inventories.
12. Interest and other borrowing costs are usually
considered as not relating to bringing the inventories to their present
location and condition and are, therefore, usually not included in the cost of
inventories.
Exclusions from the Cost of Inventories
13. In determining the cost of inventories in
accordance with paragraph 6, it is appropriate to exclude certain costs and
recognise them as expenses in the period in which they are incurred. Examples
of such costs are:
(a) abnormal amounts of wasted materials, labour,
or other production costs;
(b) storage costs, unless those costs are
necessary in the production process prior to a further production stage;
(c) administrative overheads that do not
contribute to bringing the inventories to their present location and condition;
and
(d) selling and distribution costs.
Cost Formulas
14. The
cost of inventories of items that are not ordinarily interchangeable and goods
or services produced and segregated for specific projects should be assigned by
specific identification of their individual costs.
15. Specific identification of cost means that
specific costs are attributed to identified items of inventory. This is an
appropriate treatment for items that are segregated for a specific project,
regardless of whether they have been purchased or produced. However, when there
are large numbers of items of inventory which are ordinarily interchangeable,
specific identification of costs is inappropriate since, in such circumstances,
an enterprise could obtain predetermined effects on the net profit or loss for
the period by selecting a particular method of ascertaining the items that
remain in inventories.
16. The cost of inventories, other than those
dealt with in paragraph 14, should be assigned by using the first-in, first-out
(FIFO), or weighted average cost formula. The formula used should reflect the
fairest possible approximation to the cost incurred in bringing the items of
inventory to their present location and condition.
17. A variety of cost formulas is used to
determine the cost of inventories other than those for which specific
identification of individual costs is appropriate. The formula used in
determining the cost of an item of inventory needs to be selected with a view
to providing the fairest possible approximation to the cost incurred in
bringing the item to its present location and condition. The FIFO formula
assumes that the items of inventory which were purchased or produced first are
consumed or sold first, and consequently the items remaining in inventory at
the end of the period are those most recently purchased or produced. Under the
weighted average cost formula, the cost of each item is determined from the weighted
average of the cost of similar items at the beginning of a period and the cost
of similar items purchased or produced during the period. The average may be
calculated on a periodic basis, or as each additional shipment is received,
depending upon the circumstances of the enterprise.
Techniques for the Measurement of Cost
18. Techniques for the measurement of the cost of
inventories, such as the standard cost method or the retail method, may be used
for convenience if the results approximate the actual cost. Standard costs take
into account normal levels of consumption of materials and supplies, labour,
efficiency and capacity utilisation. They are regularly reviewed and, if
necessary, revised in the light of current conditions.
19. The retail method is often used in the retail
trade for measuring inventories of large numbers of rapidly changing items that
have similar margins and for which it is impracticable to use other costing
methods. The cost of the inventory is determined by reducing from the sales value
of the inventory the appropriate percentage gross margin. The percentage used
takes into consideration inventory which has been marked down to below its
original selling price. An average percentage for each retail department is
often used.
Net Realisable Value
20. The cost of inventories may not be recoverable
if those inventories are damaged, if they have become wholly or partially
obsolete, or if their selling prices have declined. The cost of inventories may
also not be recoverable if the estimated costs of completion or the estimated
costs necessary to make the sale have increased. The practice of writing down
inventories below cost to net realisable value is consistent with the view that
assets should not be carried in excess of amounts expected to be realised from
their sale or use.
21. Inventories are usually written down to net
realisable value on an item-by-item basis. In some circumstances, however, it
may be appropriate to group similar or related items. This may be the case with
items of inventory relating to the same product line that have similar purposes
or end uses and are produced and marketed in the same geographical area and
cannot be practicably evaluated separately from other items in that product
line. It is not appropriate to write down inventories based on a classification
of inventory, for example, finished goods, or all the inventories in a
particular business segment.
22. Estimates of net realisable value are based on
the most reliable evidence available at the time the estimates are made as to
the amount the inventories are expected to realise. These estimates take into
consideration fluctuations of price or cost directly relating to events
occurring after the balance sheet date to the extent that such events confirm
the conditions existing at the balance sheet date.
23.
Estimates of net realisable value also
take into consideration the purpose for which the inventory is held. For
example, the net realisable value of the quantity of inventory held to satisfy
firm sales or service contracts is based on the contract price. If the sales
contracts are for less than the inventory quantities held, the net realisable
value of the excess inventory is based on general selling prices. Contingent
losses on firm sales contracts in excess of inventory quantities held and
contingent losses on firm purchase contracts are dealt with in accordance with
the principles enunciated in Accounting Standard (AS) 4, Contingencies andEvents Occurring After the Balance Sheet Date.
24. Materials and other supplies held for use in
the production of inventories are not written down below cost if the finished
products in which they will be incorporated are expected to be sold at or above
cost. However, when there has been a decline in the price of materials and it
is estimated that the cost of the finished products will exceed net realisable
value, the materials are written down to net realisable value. In such
circumstances, the replacement cost of the materials may be the best available
measure of their net realisable value.
25.
An assessment is made of net
realisable value as at each balance sheet date.
Disclosure
26. The financial statements should disclose:
(a) the accounting policies adopted in measuring
inventories, including the cost formula used; and
(b) the total carrying amount of inventories and
its classification appropriate to the enterprise.
27. Information about the carrying amounts held in
different classifications of inventories and the extent of the changes in these
assets is useful to financial statement users. Common classifications of
inventories are raw materials and components, work in progress, finished goods,
stores and spares, and loose tools.
