Work-outs
Work-outs (often referred to as Arbitrage) are securities whose financial results depend on a specific corporate action—such as a merger, liquidation, reorganization, or spin-off—rather than the general direction of the stock market.
📍 Origin
The category was first defined in the 1957 Letter.
"These are securities whose financial results depend on corporate action... rather than supply and demand for the stock. They are a predictable group, and in a year when the market is down as a whole, they will outperform the market."
📅 Chronological Evolution
-
1960 Letter: Buffett outlines the "non-correlated" nature of work-outs.
- Quote: "We try to have a large enough group of these so that we can have a predictable result regardless of what the Dow does."
- Shift: He notes the use of leverage (borrowed funds) to finance these positions, up to 25% of the partnership's net worth.
-
1962 Letter: Introduction of hedging.
- Shift: For the first time, Buffett mentions using Short Selling to reduce market risk in specific work-outs. This was a response to the volatile market of 1962.
-
1964 Letter: "Creating" Work-outs.
- Logic: Buffett describes situations where the partnership buys a large enough block (but not yet control) to effectively "create" a work-out by forcing a tender offer or liquidation.
- Quote: "In some cases we have a large enough position to influence the corporate action, changing a 'General' into a 'Work-out'."
-
1987 Letter: Long-term Track Record.
- Stats: Buffett reveals that over several decades, Berkshire's arbitrage operations have averaged annual pre-tax returns of at least 25%.
- Scale: In 1987, Berkshire practiced arbitrage on a limited scale, with the only major position ($50M+) being Allegis (cost $76M, market value $78M).
- Risk Warning: Buffett notes that while returns are high, a "really bad experience or two" can change the figures dramatically, referring to the losses many arbitrageurs suffered in the October 1987 crash (though Berkshire remained profitable).

🌱 Idea Evolution & Maturity
How this concept developed over time, tracking its transformation from an early practice to a formalized Berkshire pillar.
The Graham Arbitrage
Buffett engages in 'work-outs'—merger arbitrage, liquidations, and reorganizations—as a way to generate uncorrelated returns.
Work-outs provide a place to park cash where the return depends on corporate events rather than market movements.
Work-outs are securities whose financial results depend on corporate action rather than supply and demand factors in the stock market.
The Formal Category
Buffett formally classifies 'work-outs' as one of the major categories of Berkshire's equity investments.
When markets are overvalued, work-outs offer a mathematically definable return that is independent of market crashes.
We use work-outs to keep our money busy when we can't find good long-term investments.
The Arcata Lesson
Buffett details the math of risk arbitrage: probability of success, time to completion, and opportunity cost.
Arbitrage is not risk-free. If a deal breaks, the loss is usually massive compared to the potential gain. You must price the risk perfectly.
To evaluate an arbitrage situation, you must answer four questions... the most important is 'what is the chance the deal breaks?'
The Sidelined Strategy
Work-outs become an insignificant part of Berkshire's strategy because the absolute dollar returns are too small to move the needle.
The strategy works, but it does not scale to hundreds of billions of dollars. Berkshire transitions fully to 'permanent' equity holdings and wholly-owned businesses.
The days of us making significant money from work-outs are over. We are simply too big.
