1. Overview

Why Study Buffett's Early Deals?

• The early deals are more instructive than the later mega-deals because they are replicable by individual investors. Buying Coca-Cola requires billions; buying net-nets requires thousands.
• The evolution from Graham-style deep value to Munger-influenced quality investing is visible in the progression of deals.
• Each deal reveals a specific lesson about valuation, psychology, or competitive advantage.

The Arc of Buffett's Career

1941-1950: Childhood — first stock purchases, paper route savings
1950-1956: Education — Columbia (under Graham), first professional investing
1956-1969: Partnership — Buffett Partnership Ltd, compounding at 29.5%/year
1969-present: Berkshire Hathaway — from textile mill to $700B+ conglomerate

This book covers the first three phases in detail, with early Berkshire deals establishing the transition to the fourth.

"I am a better investor because I am a businessman, and I am a better businessman because I am an investor." — Warren Buffett

2. The Early Years: Formation of an Investor

2.1 The Childhood Foundation

• At age 6, Buffett bought packs of Coca-Cola for 25 cents and sold individual bottles for 5 cents each — a 20% profit margin. His first "business."
• At age 11, bought his first stock: Cities Service Preferred at $38 per share.
• At age 13, filed his first tax return, deducting his bicycle as a business expense for his paper route.
• By age 15, had saved $2,000 from his paper route — equivalent to roughly $30,000 today.

2.2 The Graham Education

• At age 19, read The Intelligent Investor by Benjamin Graham. Called it "the most important book on investing ever written."
• Enrolled at Columbia Business School specifically to study under Graham.
• Learned the core Graham principles:
  • Mr. Market: the market is a manic-depressive partner who offers to buy or sell at irrational prices.
  • Margin of safety: the difference between price and value is your protection.
  • Quantitative analysis: focus on numbers, not narratives.

2.3 Working for Graham

• After Columbia, Buffett worked at Graham-Newman Corporation (1954-1956).
• Learned the mechanics of deep value investing: buying net-nets, special situations, arbitrage.
• Key lesson from Graham: "You are not right or wrong because the crowd disagrees with you. You are right because your data and reasoning are right."

3. The Partnership Era (1956-1969)

3.1 Buffett Partnership Ltd

• Started in 1956 with $105,100 from seven limited partners.
• Buffett invested $100 of his own money (his wealth was modest at the time).
• Fee structure: 0% management fee, 25% of profits above 6% hurdle rate.
• This aligned interests perfectly — Buffett earned nothing unless partners earned at least 6%.

3.2 Performance Record

Year    Partnership Return    Dow Jones Return    Outperformance
1957         10.4%               -8.4%              +18.8%

Cumulative (1957-1969): Partnership 2,794% vs Dow 152%
CAGR: ~29.5% vs ~7.4%

3.3 Three Categories of Partnership Investments

Buffett divided his investments into three categories:

1. Generals: undervalued stocks with no specific catalyst. Bought below intrinsic value, waited for market to recognize the value.
2. Workouts: special situations — mergers, liquidations, reorganizations. Returns independent of market direction.
3. Controls: positions large enough to influence corporate policy. Buffett would take control and unlock value directly.

---

4. Deal: Cities Service Preferred (First Stock)

Context

• Year: 1941. Buffett was 11 years old.
• Bought 3 shares of Cities Service Preferred at $38 per share.
• Also bought 3 shares for his sister Doris.

What Happened

• The stock dropped to $27 shortly after purchase. Doris reminded him every day of the loss.
• When the stock recovered to $40, Buffett sold — a profit of $2 per share ($6 total).
• Cities Service subsequently rose to over $200 per share.

Lessons Learned

1. Do not anchor on your purchase price. The market does not care what you paid.
2. Patience pays. Selling a winner early to avoid the pain of a potential reversal is expensive.
3. Do not let others' emotions (Doris) influence your decisions.
4. Understand what you own. Buffett had not fully analyzed Cities Service — he was speculating, not investing.

---

5. Deal: GEICO (First Major Insight)

Context

• Year: 1951. Buffett was 20, studying under Graham at Columbia.
• Discovered that Graham was chairman of GEICO (Government Employees Insurance Company).
• Traveled to GEICO's offices on a Saturday. Met Lorimer Davidson, who spent four hours explaining the business.

What Buffett Saw

• Cost advantage: GEICO sold auto insurance directly to customers, bypassing agents. This gave it a 10-15% cost advantage over competitors.
• Growth potential: direct-to-consumer insurance was in its infancy. GEICO had a massive addressable market.
• Quantitative cheapness: the stock traded at reasonable multiples despite the growth potential.

The Investment

• Buffett invested $10,282 — 65% of his net worth at the time — in GEICO stock.
• Held for about a year, sold at approximately 50% profit.
• Later regretted selling — GEICO continued to compound for decades.

Lessons Learned

1. Durable cost advantage is the most powerful moat. A company that can deliver the same product at structurally lower cost will win over time.
2. Concentration pays when conviction is high. Putting 65% of net worth in one stock is extreme but was warranted by the depth of Buffett's understanding.
3. Selling too early is costly. This reinforced the Cities Service lesson.
4. Go directly to the source. Buffett learned more from four hours with Davidson than from any annual report.

"It was like finding a new girl — I had a tremendous interest in the company."

6. Deal: Sanborn Map Company

Context

• Year: 1958-1960. Early partnership era.
• Sanborn Map Company made detailed maps of American cities for fire insurance underwriting.
• The map business was declining as insurance companies developed alternative methods.

What Buffett Saw

• Investment portfolio: Sanborn held an investment portfolio worth approximately $65 per share.
• Stock price: $45 per share.
• The market was valuing the map business at NEGATIVE $20 per share ($45 stock price minus $65 portfolio value).
• In reality, the map business still generated modest profits.

Valuation at Purchase

Investment portfolio per share:    $65
Map business value (conservative):  $0 (assume worthless)
Minimum intrinsic value:           $65
Market price:                      $45
Discount to asset value:           31%

The Outcome

• Buffett accumulated a controlling stake (became the largest shareholder).
• Proposed separating the investment portfolio from the map business, distributing the portfolio to shareholders.
• After board resistance, Buffett gained enough board seats to force the action.
• Shareholders received the portfolio value. Buffett's partnership realized a profit of approximately 50%.

Lessons Learned

1. Hidden assets create opportunity. The market often ignores or undervalues assets that are not part of the core business.
2. Activism can be the catalyst. When deep value exists but no catalyst is visible, becoming the catalyst yourself is a viable strategy.
3. Management may resist value-unlocking actions. Boards protect their positions, not shareholder value. Be prepared to fight.

7. Deal: Dempster Mill Manufacturing

Context

• Year: 1961-1963. Partnership era.
• Dempster Mill manufactured farm windmills and water systems in Beatrice, Nebraska.
• A small, mediocre business with poor management.

What Buffett Saw

• Net asset value: approximately $75 per share.
• Stock price: approximately $28 per share — a massive discount to liquidation value.
• Classic Graham net-net: current assets minus all liabilities exceeded the stock price.

The Approach

• Buffett accumulated shares and eventually took control (became chairman).
• Installed Harry Bottle as manager — a turnaround specialist who cut costs, reduced inventory, and improved operations.
• Within one year, Bottle transformed the business from a money-loser to a profitable operation.

Valuation at Purchase and Exit

Purchase price per share:          ~$28
Net asset value at purchase:       ~$75
Discount to NAV:                    63%

After turnaround:
Improved operations + reduced assets → NAV rose further
Exit price:                        ~$80 per share
Total return:                      ~186%

Lessons Learned

1. Graham-style net-nets can be enormously profitable. Buying at 37 cents on the dollar provides massive upside.
2. Management matters. The right manager (Harry Bottle) transformed a losing business into a winner.
3. Activist investing works at small scale. Buffett's partnership was small enough to take control of a tiny company and direct its operations.
4. This was Buffett's first hint that business quality matters. Dempster was profitable, but the experience of managing a mediocre business was unpleasant. Buffett began to appreciate quality businesses.

---

8. Deal: American Express (The Salad Oil Scandal)

Context

• Year: 1963-1964. One of Buffett's most famous partnership investments.
• American Express was hit by the "salad oil scandal" — a fraudster named Tino De Angelis had obtained loans from AmEx's warehouse subsidiary using fake soybean oil collateral.
• AmEx's contingent liability was estimated at $60 million — a large sum for the company at the time.
• The stock dropped from $65 to $35.

What Buffett Saw

• The franchise was intact. Buffett went to restaurants and shops in Omaha and observed that people were still using American Express cards and travelers' checks. The scandal had not damaged the brand.
• The liability was containable. $60 million was a large hit but would not bankrupt American Express.
• The market was overreacting. The stock had declined 46%, implying the market expected existential damage. Buffett's analysis showed the damage was manageable.

Valuation Analysis

Pre-scandal price:                  $65
Post-scandal price:                 $35
Market implied loss of value:       $30/share ≈ 46%
Actual economic damage:             $60M / shares outstanding ≈ $6/share
Overreaction:                       $24/share of excess punishment

Intrinsic value (conservative):     $55-60
Margin of safety at $35:            ~37-42%

The Investment

• Buffett invested 40% of the partnership's assets in American Express — $13 million.
• This was an extraordinarily concentrated bet. It violated standard diversification rules.
• The conviction was based on Buffett's "scuttlebutt" research (visiting restaurants, talking to merchants) combined with quantitative analysis.

The Outcome

• AmEx settled the liabilities, the stock recovered, and Buffett's partnership earned approximately $20 million — a 150%+ return in about two years.

Lessons Learned

1. Brand value (franchise) is a powerful moat. American Express's brand survived a major scandal because customer trust ran deep.
2. Scuttlebutt research is invaluable. Going to restaurants and watching consumers use AmEx cards provided evidence that no spreadsheet could offer.
3. Temporary crises create permanent opportunities. The scandal was real, but it was not existential. The market treated it as existential.
4. Concentrate when the odds are overwhelmingly in your favor. 40% of the portfolio in one stock requires extreme conviction — but the payoff justified the concentration.

"I put one-fourth of the partnership's net worth into American Express. That was an example of what I call a workable margin of safety."

9. Deal: Berkshire Hathaway

Context

• Year: 1962-1965. This deal would define Buffett's career — though not in the way he expected.
• Berkshire Hathaway was a declining New England textile manufacturer.
• The stock was trading below book value as the textile business deteriorated.

What Buffett Originally Saw

• Classic deep value: stock price below net working capital.
• Pattern: the company would periodically close a mill, sell the assets, and use the proceeds to buy back stock. Buffett would buy before mill closures and tender into buybacks for a small profit.
• It was a trading strategy, not a long-term investment.

What Went Wrong

• Seabury Stanton, Berkshire's CEO, offered Buffett $11.50 per share in a tender offer. They had verbally agreed on this price.
• The actual tender offer came at $11.375 — 12.5 cents less than promised.
• Buffett was furious at what he perceived as a slight. He began buying more stock to take control and fire Stanton.
• He succeeded — but now owned a controlling stake in a terrible business driven by emotion, not economics.

The Lesson

Purchase price:                     ~$8-14 per share (accumulated over time)
Book value at time:                 ~$19 per share
Textile business quality:           TERRIBLE (declining, capital-intensive, no moat)
Economic return on textile ops:     ~0% (eventually negative)

Buffett later called Berkshire Hathaway the worst investment he ever made. Not because of the stock price — which worked out brilliantly due to the insurance and other businesses later acquired — but because the textile operations consumed capital that could have compounded faster elsewhere.

The Transformation

• Buffett used Berkshire as a holding company, directing its cash flow into insurance (National Indemnity), then into other acquisitions.
• The textile operations were finally shut down in 1985.
• The lesson: a bad business is a bad business, no matter how cheap. But a bad business can be a vehicle for capital allocation if managed properly.

"It was the dumbest stock I ever bought." (referring to the emotion-driven purchase)

---

10. Deal: National Indemnity

Context

• Year: 1967. Buffett's first major insurance acquisition through Berkshire.
• National Indemnity was a property-casualty insurer in Omaha, run by Jack Ringwalt.
• Ringwalt wanted to sell but was emotionally attached and would periodically change his mind.

What Buffett Saw

• Insurance float: Insurance companies collect premiums upfront and pay claims later. The money in between — the "float" — can be invested. If the insurance underwriting is disciplined, the float is essentially free leverage.
• National Indemnity had conservative underwriting — it would refuse to write policies at inadequate premiums, even if it meant losing market share.
• This discipline meant the float was high-quality: low-cost or even profitable.

The Economics of Float

Insurance Float = Premiums Collected - Claims Paid (timing difference)

IF underwriting profit >= 0:
    Cost of float = 0% (FREE MONEY to invest)
IF underwriting loss = 3% of float:
    Cost of float = 3% (still cheaper than debt)

Buffett's insight: Float grows over time as the business grows.
    If invested at 15% return and float cost is 0%:
    → Pure compounding machine

Purchase Price

• Berkshire paid approximately $8.6 million for National Indemnity.
• This single acquisition became the foundation of Berkshire's entire insurance empire — which now generates over $100 billion in float.

Lessons Learned

1. Float is the ultimate compounding tool. Free money to invest, growing every year, is the most powerful financial structure available.
2. Underwriting discipline is paramount. Unprofitable float (writing policies at inadequate premiums) is worse than no float.
3. The entire Berkshire model rests on this insight. Insurance generates float. Float gets invested in stocks and whole businesses. Returns compound on an ever-growing capital base.

11. Deal: The Washington Post

Context

• Year: 1973. The stock market was in a severe bear market (1973-1974 crash).
• The Washington Post Company (owner of the newspaper, Newsweek, and TV stations) was trading at approximately $80 million market cap.
• Buffett estimated intrinsic value at $400-500 million.

What Buffett Saw

• Massive discount to intrinsic value: 80-84% margin of safety.
• Monopoly-like franchise: The Washington Post was one of two major newspapers in DC, with a dominant market position.
• Predictable cash flows: newspapers had pricing power with both advertisers and subscribers.
• Excellent management: Katharine Graham was a strong leader who would make good capital allocation decisions.

Valuation at Purchase

Market capitalization:              $80M
Estimated intrinsic value:          $400-500M
Margin of safety:                   80-84%
Price/Earnings:                     ~5-6x
EV/EBITDA:                          ~3-4x

The market was valuing the Post at roughly what
a single TV station was worth — ignoring the newspaper,
Newsweek, and all other assets entirely.

The Outcome

• Buffett bought approximately 10% of the company for ~$10 million.
• Held for decades. The Washington Post Company ultimately returned over 100x Buffett's investment.
• Became one of the most profitable investments in Berkshire's history.

Lessons Learned

1. Bear markets create extraordinary opportunities. The 1973-1974 crash was terrifying. Most investors were selling. Buffett was buying.
2. Monopoly franchises are the best investments. A dominant newspaper with pricing power is as close to a sure thing as investing offers.
3. Wide margins of safety reduce risk to near zero. At 80%+ discount to intrinsic value, almost everything that can go wrong is already priced in.
4. Management quality amplifies returns. Katharine Graham used free cash flow to buy back stock, boosting per-share value.

12. Deal: See's Candies

Context

• Year: 1972. Berkshire acquired See's Candies for $25 million.
• See's was a West Coast boxed chocolate brand with strong customer loyalty.
• Revenue: $30 million. Pre-tax income: $5 million.

What Buffett Saw (The Charlie Munger Influence)

• Pricing power: See's could raise prices every year without losing customers. This indicated a powerful brand moat.
• Low capital requirements: See's needed very little reinvestment to maintain and grow the business. Almost all earnings were free cash flow.
• Consumer monopoly: Customers perceived See's chocolates as a premium product with no close substitute. They bought See's for gifts — price sensitivity was low.

Valuation at Purchase

Purchase price:                     $25M
Pre-tax earnings:                   $5M
Price / Pre-tax earnings:           5x
Tangible assets:                    ~$8M
Premium over tangible assets:       $17M (paying for brand + earning power)

This was expensive by Graham's standards — Buffett was paying 3x tangible book value. But Munger convinced him that the earning power and pricing power justified the premium.

The Outcome

• Over the next 40 years, See's generated over $2 billion in cumulative pre-tax earnings.
• These earnings required minimal reinvestment and were deployed by Berkshire into other investments.
• See's was the investment that crystallized Buffett's shift from "cigar butt" value investing to quality investing.

Lessons Learned

1. Pricing power is the single most important quality of a business. If you can raise prices without losing customers, you have a great business.
2. Low capital intensity creates free cash flow machines. A business that earns $5M and needs $0 reinvested is infinitely better than one that earns $5M and needs $4M reinvested.
3. Brand moats are real and durable. See's brand was strong in 1972 and remains strong today.
4. Paying a fair price for a wonderful business beats paying a wonderful price for a fair business. This was the pivot from Graham to Munger-influenced investing.

"See's Candies taught me the power of brands. It was the first time I was willing to pay up for quality."

13. Deal: GEICO (The Rescue)

Context

• Year: 1976. GEICO, the company Buffett had first invested in 25 years earlier, was now on the verge of bankruptcy.
• Aggressive expansion and poor underwriting had created massive losses.
• The stock dropped from $61 to $2.

What Buffett Saw

• The competitive advantage still existed. Direct-to-consumer auto insurance was still fundamentally cheaper than agent-based distribution.
• The problem was management, not the business model. Poor underwriting discipline had caused the losses. With disciplined management, the business would recover.
• New management was in place. Jack Byrne had been brought in and was cutting costs, tightening underwriting, and restructuring.

The Investment

• Buffett invested $4.1 million in GEICO stock and $19.4 million in GEICO convertible preferred.
• Total: approximately $23.5 million for a ~33% economic interest.

The Outcome

• GEICO recovered under Byrne's management.
• Berkshire's stake appreciated massively. By 1996, Berkshire owned ~50% of GEICO.
• In 1996, Berkshire acquired the remaining 50% for $2.3 billion — making GEICO a wholly-owned subsidiary.

Lessons Learned

1. Revisit past investments. Buffett's deep knowledge of GEICO from 1951 gave him the confidence to invest again at the crisis point.
2. Crisis creates the best buying opportunities. At $2, the market was pricing GEICO for bankruptcy. Buffett saw a temporarily impaired but fundamentally sound business.
3. Management change can be the catalyst. Jack Byrne's arrival changed the trajectory.
4. The moat was intact even through the crisis. The cost advantage of direct-to-consumer insurance did not disappear because of bad underwriting — it was waiting to be exploited by competent management.

14. Deal: Nebraska Furniture Mart

Context

• Year: 1983. Berkshire acquired 80% of Nebraska Furniture Mart for $60 million.
• The store was founded and run by Rose Blumkin ("Mrs. B"), a Russian immigrant who arrived in America in 1917 with no money and no English.
• By 1983, NFM was the largest furniture store in the United States.

What Buffett Saw

• Unbeatable cost structure: Mrs. B bought in massive volume and sold at thin margins. No competitor could match her prices.
• Customer loyalty: Omaha residents drove from hours away to buy at NFM.
• Managerial excellence: Mrs. B was still running the store at age 89, working seven days a week.
• Simplicity: The business model was straightforward — buy cheap, sell cheap, make it up on volume.

The Valuation

• Buffett paid $60 million for 80% based on a handshake — no audit, no due diligence, no lawyers.
• He trusted Mrs. B's integrity and had observed the business for years as a local customer.
• The deal was done on a single page of paper.

Lessons Learned

1. Some businesses are so well-run that complex due diligence is unnecessary. Buffett knew NFM from personal experience.
2. Cost leadership is a durable moat. Mrs. B's volume-buying advantage was structural and self-reinforcing.
3. Management character matters. Buffett trusted Mrs. B completely. She worked until age 104.
4. Simple businesses are the best businesses. Buy cheap, sell cheap, serve the customer. No technology disruption risk, no regulatory risk.

15. Deal: Capital Cities/ABC

Context

• Year: 1985. Tom Murphy's Capital Cities Communications acquired ABC for $3.5 billion — the largest media merger in history at that time.
• Murphy needed financing and called Buffett.
• Berkshire invested $517 million for a 25% stake in the combined company.

What Buffett Saw

• Tom Murphy was the best capital allocator in media. Murphy and his partner Dan Burke had an extraordinary track record of buying media properties and improving their operations.
• Media assets were franchise businesses with high barriers to entry and pricing power.
• The combination would create the largest media company in the world with enormous synergy potential.

Lessons Learned

1. Back outstanding managers. Buffett often says he bets on the jockey, not the horse. Murphy was the best jockey in media.
2. Media franchises have long-duration competitive advantages. TV stations and networks benefit from limited licenses and high barriers to entry.
3. When a great manager needs your capital, say yes. Buffett's investment in Cap Cities/ABC returned approximately 3x his money when Disney acquired the company in 1995.

16. Key Valuation Methods Used by Early Buffett

16.1 Net Current Asset Value (Graham Era)

NCAV = Current Assets - Total Liabilities
Buy when: Price < 2/3 * NCAV per share
Used for: Dempster Mill, early Berkshire, various partnership "generals"

16.2 Asset-Based Valuation (Transition Era)

Intrinsic_Value = Value_of_Investment_Portfolio + Value_of_Operating_Business
Buy when: Price < 60% of Intrinsic_Value
Used for: Sanborn Map, Berkshire Hathaway

16.3 Earnings Power Value (Munger Influence)

EPV = Normalized_Earnings / Discount_Rate
Normalized_Earnings = Sustainable_earning_power (not peak, not trough)
Buy when: Price < 60-70% of EPV
Used for: American Express, Washington Post, See's Candies

16.4 Owner Earnings (Mature Buffett)

Owner_Earnings = Net Income + Depreciation - Maintenance CapEx
Intrinsic_Value = Owner_Earnings * (8.5 + 2g) [Graham formula]
    where g = expected growth rate
Buy when: Price provides adequate margin of safety
Used for: GEICO rescue, Capital Cities/ABC, later acquisitions

---

17. The Evolution of Buffett's Approach

Phase 1: Pure Graham (1950-1967)

• Buy anything trading below net current asset value.
• No concern for business quality.
• Sell when price reaches intrinsic value.
• Works but is labor-intensive and requires constant turnover.

Phase 2: Transition (1967-1972)

• Beginning to appreciate business quality (American Express franchise).
• Still attracted to statistical cheapness (Berkshire Hathaway).
• Starting to hold positions longer.
• Influenced by Phil Fisher's qualitative analysis and Charlie Munger's quality focus.

Phase 3: Quality at a Fair Price (1972+)

• See's Candies was the turning point.
• Willing to pay fair prices for exceptional businesses with durable moats.
• Focus on pricing power, low capital requirements, and excellent management.
• Holding period: "forever" for the right business.

Graham Buffett:     Buy $1 for $0.50 → Sell when it reaches $1 → Repeat
Munger Buffett:     Buy $1 of quality for $0.70 → Hold as $1 grows to $5 to $20+

The Munger approach generates higher long-term returns because:

1. No need to constantly find new ideas.

2. Tax-deferred compounding (no capital gains from selling).

3. Quality businesses compound intrinsic value over time.

4. Start with the numbers. Every deal in this book began with quantitative analysis — net asset value, earnings power, cash flow yield. The qualitative narrative came second.

5. The price you pay determines your safety. Whether Buffett was buying net-nets at 37 cents on the dollar or the Washington Post at 20 cents on the dollar, the margin of safety was always wide.

6. Temporary problems create permanent opportunities. American Express (salad oil scandal), GEICO (near-bankruptcy), Washington Post (1973-74 crash) — every crisis was temporary, but the discount was enormous.

7. Business quality evolves your returns. The shift from Graham to Munger was the most important evolution in Buffett's career. Quality businesses compound intrinsic value; cheap businesses just revert to fair value.

8. Pricing power is the ultimate moat. See's Candies could raise prices every year. American Express could charge merchants fees. The Washington Post could charge advertisers. Pricing power is the single most reliable indicator of business quality.

9. Float is free leverage. The National Indemnity acquisition revealed the most powerful financial structure available to investors. Insurance float, deployed wisely, is the ultimate compounding tool.

10. Management character is non-negotiable. Mrs. B (Nebraska Furniture Mart), Tom Murphy (Capital Cities), Jack Byrne (GEICO) — Buffett consistently backed managers of exceptional integrity and ability.

11. Concentrate when the odds are overwhelming. 40% of the partnership in American Express. 65% of net worth in GEICO at age 20. Concentration amplifies returns when the analysis is thorough and the margin of safety is wide.

12. Go to the source. Buffett visited GEICO offices, counted American Express cards at restaurants, and bought furniture from Mrs. B. Primary research produces insights that secondary research cannot.

13. The best time to invest is when everyone else is afraid. Every major deal in this book was made during a period of fear — market crashes, corporate scandals, or industry crises. Fear creates the discounts that value investors need.
