Chapter 6: Reporting and Analyzing Inventory and COGS

Chapter 6: Reporting and Analyzing Inventory and Cost of Goods Sold

Learning Objectives
  • Types of Inventories: Understand inventories held by both merchandisers and manufacturers and how these costs flow through a company.

  • Inventory Transactions: Record purchases and sales of inventory using a perpetual inventory system.

  • Inventory Costing Methods: Apply three inventory costing methods (Specific Identification, FIFO, Weighted Average Cost) to compute ending inventory and cost of goods sold.

  • Financial Reporting Effects: Analyze the financial reporting and tax implications of different inventory costing methods.

  • Lower of Cost and Net Realizable Value: Apply the LCM rule for inventory valuation.

  • Inventory Management: Evaluate inventory management using gross profit and inventory turnover ratios.

  • Errors in Inventory: Understand how errors in ending inventory affect financial statements.

  • Periodic Inventory System: Record purchases using a periodic inventory system and compute ending inventory and cost of goods sold under this system.

Nature of Inventory and Cost of Goods Sold
  • Inventory as a Current Asset: Products held for resale, classified as current assets.

  • Cost of Goods Sold (COGS):

    • An expense representing the cost of inventory sold to customers.

    • Gross margin is calculated as Revenue - COGS.

Types of Inventories
  • Merchandisers:

    • Retailers: Sell directly to consumers.

    • Wholesalers: Sell to retailers.

    • Merchandise inventory: Finished goods held for resale.

  • Manufacturers:

    • Transform raw materials into finished goods.

    • Classification of inventory:

    • Raw materials: Basic ingredients.

    • Work-in-process: Current production costs.

    • Finished goods: Completed products ready for sale.

Flow of Inventory Costs
  • Cost Components: Cost includes purchase price, freight charges, insurance, taxes.

  • Shipping Terms: Determines cost bearing and ownership transition:

    • F.O.B. Shipping Point: Title passes at shipping point; buyers pay transportation (freight-in).

    • F.O.B. Destination: Title passes at delivery; sellers pay transportation (freight-out).

Perpetual vs. Periodic Inventory Systems
  • Perpetual System: COGS is updated with each sale.

  • Periodic System: COGS recorded only at period end, inventory updated with physical count.

Inventory Transactions in Perpetual System
  1. Recording Purchases: Increase the inventory account; purchase invoices track costs and discounts.

  2. Sales Entries: Recognize sales and reduce inventory for goods sold.

  3. Sales Returns: Use contra-revenue accounts to adjust sales and inventory for returns.

Inventory Costing Methods
  • Cost Allocation: Allocate costs between ending inventory and COGS.

    • Key methods:

    1. Specific Identification: Track actual costs for individual items; suitable for high-cost items.

    2. FIFO (First-In, First-Out): Assumes oldest inventory is sold first; reflects physical flow in many cases.

    3. Weighted Average Cost: Uses a moving average after each purchase to allocate costs.

Effects of Inventory Costing Choices
  • Financial Statements: Different methods affect net income, tax payments, and asset valuation.

  • Income Tax: Short-term choices can defer tax payments but do not eliminate them.

  • Lower of Cost and Net Realizable Value (LCNRV): Value inventory at the lower of its cost or net realizable value; reduces inventory valuation if necessary.

Analyzing Inventory Management
  • Key Ratios: Gross Profit Ratio = Gross Profit/Net Sales

  • Inventory Turnover Ratio = COGS/Average Inventory

  • Average Days to Sell Inventory = 365/Inventory Turnover Ratio.

Periodic Inventory System Transactions
  • Track purchases as temporary accounts until physical count; includes purchases, discounts, returns, and transportation.

  • Inventory costing methods also apply under periodic systems, but with different approaches for calculating ending inventory and COGS.

Effects of Inventory Errors
  • Impact two accounting periods; ending inventory of one period becomes the beginning inventory of the next. Errors can lead to understating/overstating:

    • COGS, net income, total assets.

Key Differences Under IFRS and ASPE
  • Current trends indicate convergence of accounting standards, but minor differences still exist between IFRS (IAS 2) and ASPE (CPA Canada Handbook Section 3031).
