• Objective: Explain the financial statement effects of inventory cost determination methods.

Choice of Cost Determination Method

• Consistency in Cost Formula:
  • The same cost determination method should be applied consistently across accounting periods.
  • Benefits of Consistent Use:
  • Enhances the comparability of financial statements over time.
  • It is essential to choose a method that best aligns with the actual physical flow of inventory.
  • Use the same method for all inventories that share a similar nature and purpose of use.

Financial Statement Effects

• Impact on Income Statement:

  • When prices are rising:
  • The FIFO (First-In, First-Out) method generates higher profit margins.
  • When prices are falling:
  • The opposite occurs; FIFO may report lower profits.

• Impact on Balance Sheet:

  • FIFO method provides a valuation of inventory that is most reflective of current costs.
  • This method closely approximates the replacement costs of the inventory items.
