Bases of Inventory Valuation

• Acquisition cost – historical cost of items• Standard cost – an estimate of what inventory

items should cost• Net realizable cost – amount that a company

could realize as a willing seller with a willing buyer

• Replacement cost – amount the company would have to pay to acquire the item

• Lower-of-cost-or-market-basis – lesser of acquisition cost and market value

Inventory Adjustment

Item cost may need to be adjusted if:• The item is valued according to FIFO or LIFO

costing methods• Unit cost is changed due to additional direct

cost• The item is valued at average cost• Sales occur before purchase

Inventory Adjustment

Ways of adjusting inventory costs:• Adjust Cost – Item Entries batch job

– For each item– For each item category– For all items

• Automatic adjustment– Daily– Weekly– Monthly– Yearly– Always (when posting occurs)

Average costing method

Other costing methodsSeparate rounding entry

Cumulative rounding entry

Session 1 Summary• Costs are classified as:

– Capitalized, non-capitalized– Inventoriable, non-inventoriable

• Direct costs are traced to the cost object, indirect costs – allocated to the cost object

• Supported cost flow assumptions are FIFO, LIFO, Weighted Average

• Inventory posting is comprised of quantity and value posting• Posting flow includes creation of the following entries:

– Value entries– Item ledger entries– General ledger entries

• Inventory periods help with posting of inventory transactions

Session 1 Summary

• Unit cost on purchase line is retrieved based on the item’s costing method

• Unit cost on sales line depends on how the link is established between the inventory increase and decrease

• Supported costing methods are FIFO, LIFO, Average, Specific, Standard

• Entry application can be of two types:– Based on the costing method– Fixed application

• Average cost depends on the valuation date• Non-inventoriable costs can be recorded as item charges

Session 1 Summary

• Inventory transfers are valued using the transfer application• Inventory returns are valued using the fixed application• Inventory costs need to be adjusted automatically or using the

adjustment batch job• Rounding is facilitated by creating cumulative or standalone

rounding value entries

The Post Inventory Cost to G/L Batch Job

Processing Algorithm:

1. Determine the posting method.2. Determine whether expected cost posting is enabled.3. Calculate the amounts to be posted:

Amount to be posted = Cost Amount (Actual) - Cost Posted to G/L4. Create general ledger entries for the calculated amounts.5. Update the Cost Posted to G/L field:

Cost Posted to G/L = Cost Amount (Actual)6. Update the Cost is Posted to G/L field on the item card.7. Display the report.

Tracing G/L Entries

General ledger entries can be traced to underlying value and item ledger entries because of the following features:

• Inventory – G/L Reconciliation tool– Displays reconciliation differences between the inventory

ledger and G/L– Allows to drill-down to specific entries– Exposes the reasons for reconciliation differences

• Links between value and general ledger entries– One-to-one relation– One-to-many relation

Inventory Revaluation

Revaluable quantity = Sum of quantities on invoiced item ledger entries for all inventory increases and decreases with posting dates equal or earlier than the revaluation date• For standard-valued items, expected costs can also be revalued (interim

inventory accounts in G/L will be affected)

Ways of performing revaluation in the revaluation journal:• Entering a line manually and applying it to the item ledger entry in

question• Running the Calculate Inventory Value batch job

Inventory Costing Setup

Inventory Costing Setup

The setup of Inventory Costing consists of:• Setup of inventory periods• General setup

– Automatic Cost Posting– Expected Cost Posting to G/L– Average Cost Calculation Type– Average Cost Period

• Individual item setup– Costing Method

Session 2 Summary

• Inventory is valued based on value entries.• Inventory cost is posted to the income statement and balance

sheet accounts in the General Ledger based on the types of value and item ledger entries.

• The Post Inventory Cost to G/L batch job can post per entry or per posting group.

• Expected inventory value can be posted to interim inventory accounts.

• General ledger entries can be traced down to underlying value and item ledger entries.

Session 2 Summary

• Revaluation is based on actual cost (or expected cost for standard-valued items).

• The Calculate Inventory Value batch job allows to perform inventory revaluation to a wider extent.

• Physical inventory counting helps resolve differences between the actual and calculated quantity of items on hand.

• Inventory costing setup reflects the way the company decides to control and account for its inventory value.
