Final answer:
Inventory cost calculation methods like FIFO, LIFO, and the average method significantly impact financial statements, with FIFO usually leading to a higher ending inventory and lower COGS during inflation, and LIFO resulting in the opposite. These methods affect financial performance, decision-making, and inventory management.
Step-by-step explanation:
The choice of inventory cost calculation methods, such as FIFO (First-In, First-Out), LIFO (Last-In, First-Out), and the average method, plays a pivotal role in influencing a firm's financial statements. Under the FIFO method, during periods of inflation, the oldest (and typically cheaper) inventory costs are allocated to the cost of goods sold (COGS), leading to a lower COGS and a higher ending inventory value. Conversely, LIFO assigns the newest (and often more expensive) costs to COGS, resulting in a higher COGS and a lower ending inventory compared to FIFO. The average method smooths out these extremes by averaging the cost of inventory over time.
Considering inflation, I agree that FIFO typically results in the highest ending inventory value and the lowest COGS, with LIFO causing the opposite effect. This is because, under inflation, newer inventory will generally be more expensive due to rising prices, making the cost of goods sold higher when the latest costs are used as is the case with LIFO.
The selected inventory valuation method can lead to significant discrepancies in financial performance and decision-making. A company using FIFO might show higher profits and pay more taxes during inflationary times, while one using LIFO could report lower profits but benefit from lower tax liabilities. These differences also affect a company's inventory management strategies and can influence borrow capacity due to the impact on the balance sheet.
