LIFO Inventory Pricing
LIFO (Last-In, First-Out) is an inventory valuation method where the items purchased most recently are assumed to be the ones sold first. Buffett is a strong advocate of LIFO during periods of inflation because it matches current costs against current revenues, thereby reducing "fictional" profits and the resulting taxes.
📍 Origin
Berkshire Hathaway adopted LIFO in 1973 for its Textile Operations and other manufacturing units. In the 1973 Letter, Buffett announced the shift, citing the extraordinary price rises in raw materials. In the 1974 Letter, he provided a detailed defense of the method, explaining how LIFO acts as a shield against the Inflation Tax.
🧠 The Core Argument
- The Premise: In an inflationary environment, the nominal cost of replacing inventory rises constantly. Under FIFO (First-In, First-Out), a business matches old, lower costs against current, higher sales prices, reporting high "inventory profits."
- The Mechanism: These inventory profits are purely paper gains; the business cannot distribute this cash because it must immediately spend it to replace the sold inventory at the new, higher prices. However, the government taxes these fictional profits in real cash. Under LIFO, the business matches the newest, highest costs against current revenues, reducing reported profits and lowering cash taxes.
- The Conclusion: LIFO protects the physical capital of the business by minimizing cash tax outflows during inflationary periods, even though it results in lower reported accounting earnings.
📅 Chronological Evolution
- 1973 Letter: Buffett announces the adoption of LIFO for several subsidiaries due to skyrocketing raw material prices.
- 1974 Letter: Buffett explains that LIFO protects real capital against the inflation tax. He notes that while LIFO reduces reported earnings, it increases cash flow by reducing the company's tax liability.
- 1979 Letter: Buffett explains the "paper trap" of FIFO. Companies using FIFO during inflation are essentially liquidating their real assets while reporting fake profits. LIFO, by contrast, preserves the Owner Earnings of the business by acknowledging the higher cost of replacing inventory.
- 1980 Letter: Buffett criticizes corporate managers who refuse to adopt LIFO because they are afraid of reporting lower earnings to Wall Street. He calls this a costly mistake, as it prioritizes accounting appearances over real economic cash flow.
🗣️ Primary Source Quotes
"Because of the extraordinary price rises in raw materials during 1973, which show signs of continuing in 1974, we have elected to adopt the 'lifo' method of inventory pricing. This method more nearly matches current costs against current revenues, and minimizes inventory 'profits' included in reported earnings." — Warren Buffett, 1973 Letter
"The use of LIFO is a significant method of protecting the real capital of a business against the erosion of the 'inflation tax.' It ensures that we are not paying taxes on inventory profits that are merely a result of rising prices." — Warren Buffett, 1974 Letter

🌱 Idea Evolution & Maturity
How this concept developed over time, tracking its transformation from an early practice to a formalized Berkshire pillar.
The Transition
Transitioning Berkshire's textile and retail divisions from FIFO (First-In, First-Out) to LIFO pricing.
Understanding that high inflation makes traditional FIFO accounting dangerous because it creates taxable, non-cash inventory profits.
Because of the extraordinary price rises in raw materials during 1973, which show signs of continuing in 1974, we have elected to adopt the 'lifo' method of inventory pricing.
The Capital Shield
Explaining how LIFO protects the physical capital of a business from being taxed away.
Under inflation, inventory profits are a mirage. If a business must pay cash taxes on the rise in inventory value, it is actually liquidating its real assets.
The use of LIFO is a significant method of protecting the real capital of a business against the erosion of the 'inflation tax.' It ensures that we are not paying taxes on inventory profits that are merely a result of rising prices.
Fictional Profit Critique
Buffett writes extensive letters critiquing companies that use FIFO to report higher earnings to Wall Street, calling it a self-inflicted tax wound.
Reporting high FIFO profits to please shareholders is a terrible trade-off if it results in paying real cash taxes on fictional profits.
With FIFO, you pay taxes on profits that are purely a result of rising prices, and then you must reinvest those taxed dollars just to maintain the same physical volume of inventory.
Tax and Valuation Standard
LIFO remains the default accounting method for Berkshire's manufacturing, service, and retailing subsidiaries (e.g., Precision Steel, McLane) to minimize cash taxes.
LIFO is a permanent cash management tool, though less critical to the overall group as Berkshire shifts away from capital-intensive manufacturing to service and insurance.
We continue to use LIFO where appropriate, saving millions in cash taxes that are better deployed in other operations.
