Inventory and Merchandizing Operations

Introduction

This section covers the accounting principles and procedures related to inventory and merchandising operations, including the nature of inventory, recording inventory transactions, inventory costing methods, and the evaluation of inventory management using financial ratios.

Nature of Inventory and Retailing Operations

Inventory in Financial Accounting

  • Inventory refers to goods held for resale (merchandisers) or for use in production (manufacturers).

  • When inventory is sold, its cost shifts from an asset (Inventory) to an expense (Cost of Goods Sold) on the income statement.

  • For manufacturers, inventory includes raw materials, work in progress (WIP), and finished goods.

Recording Inventory-Related Transactions

Journal Entries for Inventory Transactions

  • Purchasing inventory increases the Inventory account (asset) and increases Accounts Payable (liability) if bought on credit.

  • Selling inventory increases Sales (revenue) and Accounts Receivable (if on credit), while Cost of Goods Sold (expense) is recorded and Inventory is decreased.

Example Journal Entries:

Tracking

Keeps a running total of all goods bought, sold, and on hand

Does not keep a running total; inventory counted at least once a year

Inventory Costing Methods

Overview

  • Inventory costing methods determine how costs are assigned to inventory and cost of goods sold.

  • Main methods: Specific Unit, First-In, First-Out (FIFO), Last-In, First-Out (LIFO), Average Cost.

Specific Unit Method

  • Used for unique, high-value items (e.g., automobiles, jewelry).

  • Inventory recorded at the specific cost of each unit.

  • Not practical for homogeneous goods.

First-In, First-Out (FIFO)

  • Assumes oldest inventory items are sold first.

  • Ending inventory consists of most recent purchase costs.

  • Favored by IFRS.

Example:

Beg balance

10 units @ $10 = $100

Purchases

25 units @ $14 = $350 25 units @ $18 = $450

Cost of goods sold (40 units)

10 @ $10 = $100 25 @ $14 = $350 5 @ $18 = $90

Ending Balance

20 units @ $18 = $360

Last-In, First-Out (LIFO)

  • Assumes most recent inventory items are sold first.

  • Oldest costs remain in ending inventory.

  • Not allowed under IFRS.

Example:

Beg balance

10 units @ $10 = $100

Purchases

25 units @ $14 = $350 25 units @ $18 = $450

Cost of goods sold (40 units)

25 @ $18 = $450 15 @ $14 = $210

Ending Balance

10 units @ $10 = $100 10 units @ $14 = $140

Average Cost Method

  • Calculates a weighted average cost per unit for all inventory available for sale.

  • Cost of goods sold and ending inventory are based on this average cost.

Formulas:

  • Average cost per unit:

  • Cost of goods sold:

  • Ending inventory:

Example:

Beg balance

10 units @ $10 = $100

Purchases

25 units @ $14 = $350 25 units @ $18 = $450

Cost of goods sold (40 units @ $15)

$600

Ending Balance

20 units @ $15 = $300

Impact of Inventory Methods on Financial Statements

Increasing Inventory Prices

Cost of Goods Sold

Ending Inventory

FIFO

Lowest (older, less expensive costs)

Highest (recent, more expensive costs)

LIFO

Highest (recent, more expensive costs)

Lowest (older, less expensive costs)

Decreasing Inventory Prices

Cost of Goods Sold

Ending Inventory

FIFO

Highest (older, more expensive costs)

Lowest (recent, less expensive costs)

LIFO

Lowest (recent, less expensive costs)

Highest (older, more expensive costs)

Additional info: LIFO is often used for tax purposes in the US, as it can reduce taxable income when prices are rising.

Principles Related to Inventories

Comparability Principle

  • Businesses should use the same accounting methods year-to-year to allow for meaningful comparisons.

  • Changes in methods are allowed but must be disclosed, including the effect on net income.

Net Realizable Value (NRV)

  • NRV is the estimated selling price in the ordinary course of business, less costs of completion and sale.

  • Inventory is reported at the lower of cost or NRV. If NRV is lower, inventory is written down.

Manufacturing Companies and Inventory

Types of Inventory

  • Raw materials: Direct materials used in production.

  • Work in progress (WIP): Unfinished products; includes direct materials, direct labor, and manufacturing overhead.

  • Finished goods: Completed products ready for sale.

Allocation of Manufacturing Overheads

  • Overheads are allocated based on normal capacity (average expected production under normal circumstances).

  • If actual production exceeds normal, overhead is allocated based on actual production.

  • If actual production is less than normal, overhead is allocated based on normal capacity, and the difference is expensed.

Example Table:

Evaluating Inventory Management

Gross Profit Percentage

  • Measures a company's ability to cover operating costs and earn a profit.

Inventory Turnover

  • Indicates how efficiently inventory is managed and sold.
