2015 Shareholder Letter Summary

The 2015 letter is Berkshire's 50th-year anniversary document written from a position of mature, compounding strength. Book value rose 6.4% to $155,501 per A-share — a modest gain by historical standards, but one accompanied by the announcement of the largest acquisition in Berkshire's history (Precision Castparts at $32B+) and a 13th consecutive year of insurance underwriting profit. The letter contains Buffett's most sustained philosophical statement on American economic optimism — a direct rebuttal to election-year pessimism — and the most explicit critique of GAAP amortization as economically misleading. The insurance section articulates, for the first time, that underwriting income is now stable enough to include in Berkshire's intrinsic value calculation. The letter ends with the announcement of an annual meeting webcast, a quiet milestone: the institution begins preparing for a post-Buffett world.

🏢 Corporate Performance & Operations

Insurance — 13th Consecutive Underwriting Profit

Berkshire Hathaway Reinsurance Group (Ajit Jain): Float $44.1B (up from $42.5B). Underwriting profit $421M. Ajit entered Berkshire's office on a Saturday in 1986 with zero insurance experience; has since created "tens of billions of value."
General Re (Tad Montross): Float $18.6B. Underwriting profit $132M. International life reinsurance growing consistently and profitably since 1998 acquisition. Now described as "a gem."
GEICO (Tony Nicely): Float $15.1B. Underwriting profit $460M (down from $1.16B — competitive pressure, not structural). Market share 11.4% (vs. 2.5% in 1995). Annual premiums $22.6B. Tony joined at age 18; 54 years of service; CEO since 1993.
Other Primary (including Berkshire Hathaway Specialty Insurance): Float $9.9B. Underwriting profit $824M. BHSI: less than three years old, already $1B in annual premiums under Peter Eastwood.
Float Economics: Berkshire paid $24.5B in claims to 6M+ claimants in 2015. The float — if costless and long-enduring — is dramatically more valuable than GAAP accounting reflects (it deducts full float as liability).

BNSF — The Infrastructure Headline

Record Performance: Pre-tax income $6.8B (+$606M). Record $5.8B capital expenditure — "far and away the record for any American railroad, nearly three times our annual depreciation charge." Matthew Rose and Carl Ice credited.
National Importance: BNSF moves ~17% of U.S. intercity freight by revenue ton-miles; 45% more than its closest competitor. "Maintaining first-class service is not only vital to our shippers' welfare but also important to the smooth functioning of the U.S. economy."
2015 Context: Most American railroads had a disappointing 2015; BNSF maintained volume and set earnings records after a poor 2014 service performance.

Berkshire Hathaway Energy

Renewables: $16B invested. Owns 7% of U.S. wind generation, 6% of solar. Iowa utility: 47% of retail electricity from wind (committed to 58% by 2017). No rate increase in 16 years while industry rates rose 44%.
Financial Performance: Net earnings $2.37B; Berkshire's portion $2.13B. Canadian transmission utility added $170M in first full year.
Paris Climate Pledges: BHE made major commitments at Paris Climate Change Conference. "Our fulfilling those promises will make great sense, both for the environment and for Berkshire's economics."

Precision Castparts — The Elephant

Acquisition: Agreed in early 2016 for $32B+ cash — largest acquisition in Berkshire history. Closes February 2016. CEO: Mark Donegan.
Business: World's premier supplier of aerospace components; 30,466 employees; 162 plants in 13 countries. Multi-year contracts with major aircraft manufacturers.
The Credit: Todd Combs brought PCC to Buffett's attention "a few years ago" and educated him on the business. "Hiring these two was one of my best moves."
Strategic Effect: Berkshire now owns 10¼ companies that would populate the Fortune 500 standalone. PCC becomes the sixth member of the "Powerhouse Six."

Kraft Heinz & 3G Capital

Merger: Heinz merged with Kraft in 2015. Berkshire went from ~53% of Heinz ($4.25B cost) to 27% of Kraft Heinz (325.4M shares, $9.8B cost). New company: $27B annual sales.
GAAP Anomaly: GAAP required a $6.8B write-up upon merger completion. Preferred shares ($7.7B on books) expected to be redeemed at $8.32B in June — "good news for Kraft Heinz and bad news for Berkshire."
Partnership Philosophy: "We follow different paths... Their method is to buy companies that offer an opportunity for eliminating many unnecessary costs. At Berkshire, we follow an approach emphasizing avoidance of bloat."

Big Four Investments

Increased Ownership in All Four: IBM (+0.6% to 8.4%), Wells Fargo (+0.4% to 9.8%), Coca-Cola (+0.1% to 9.3%), American Express (+0.8% to 15.6%).
Combined Look-Through Earnings: $4.7B Berkshire share; only $1.8B recorded (dividends received). "The nearly $3 billion of these companies' earnings we don't report are every bit as valuable to us as the portion Berkshire records."
Bank of America Option: Unreported — right to buy 700M shares at $5B before Sept. 2021; worth $11.8B at yearend. "Effectively our fourth largest equity investment."

Finance & Financial Products

Clayton Homes: 34,397 homes sold (45% of U.S. manufactured home market). $12.8B mortgage portfolio; originate ~35% of all manufactured home mortgages. 100% risk retention model. Defended against predatory lending accusations: 2.64% foreclosure rate, 95.4% of borrowers current at yearend.
Marmon Group: Railcar fleet expanded to 133,220 units (added 25,085 cars from GE acquisition). 97% fleet leased.
Clayton Homes Mortgage Defense: "Skin in the game" as a regulatory principle — Clayton retains ~100% vs. proposed 1-5% minimums. During 2008-2009 panic: Clayton financed dealers who didn't even sell Clayton homes.

Core Themes & Insights

📊 Intrinsic Value vs. Book Value — The Widening Gap

The Mechanism: GAAP asymmetrically treats controlled businesses: write down losers, never write up winners. Over time, this creates a growing, unrecorded gap between book and intrinsic value. The 2015 letter makes this most explicit. The Evidence: In the early 1990s, book ≈ intrinsic (mostly marketable securities, marked to market). By 2015, "the large — and growing — unrecorded gains at our winners make it clear that Berkshire's intrinsic value far exceeds its book value." The Repurchase Implication: Berkshire would "be delighted to repurchase shares should they sell as low as 120% of book value." At that level, purchases would "instantly and meaningfully increase per-share intrinsic value."

See Intrinsic Value, Share Repurchase Policy, Accounting Earnings vs Economic Earnings.

🏭 Productivity & Prosperity — The American Machine

The Argument: Productivity gains are the "secret sauce" of American prosperity. Buffett traces three industries — railroads, auto insurance (GEICO history), and utilities — to illustrate how radical efficiency improvements deliver lower prices and higher profits, while freeing labor for other pursuits. The Data: 1947 railroads: 1.35M workers for 655B ton-miles. 2014: 187,000 workers for 1.85T ton-miles. Inflation-adjusted ton-mile cost fell 55%. BNSF alone: 1996: 411M ton-miles, 45,000 employees. 2015: 702M ton-miles, 47,000 employees. The Honest Offset: "When low-cost competition drove shoe production to Asia, our Dexter operation folded, putting 1,600 workers in a small Maine town out of work. Many were past the point in life at which they could learn another trade." The answer is not restraining productivity — it is safety nets (Buffett personally favors an expanded Earned Income Tax Credit).

See The American Tailwind, BNSF, GEICO, MidAmerican Energy.

💰 The American Tailwind — Optimism Against the Current

The Argument: "The babies being born in America today are the luckiest crop in history." American GDP per capita: ~$56,000 — six times the real level of 1930. Even at a "lamented" 2% annual GDP growth, compounding delivers $19,000 in additional real GDP per capita per generation. The Historical Test: "For 240 years it's been a terrible mistake to bet against America, and now is no time to start." Rockefeller's wealth couldn't buy what Buffett's neighbors now take for granted. The Political Rebuttal: Direct response to election-year pessimism. "Today's politicians need not shed tears for tomorrow's children."

See The American Tailwind, Productive Assets, Desirable GDP.

📉 GAAP Amortization — Real vs. Non-Real

The Critique: Of $1.1B in GAAP amortization charges: ~20% are "real" (software, etc.); ~80% are "non-real" (customer relationships from purchase accounting — economic fictions). "When CEOs or investment bankers tout pre-depreciation figures such as EBITDA as a valuation guide, watch their noses lengthen while they speak." The Stock Compensation Warning: "Stock-based compensation" is the more egregious failure. "If compensation isn't an expense, what is it?" Analysts who propagate "compensation-ignoring earnings" are "guilty of propagating misleading numbers that can deceive investors." The Depreciation Nuance: BNSF's GAAP depreciation understates true economic depreciation. "In 51 years I've yet to figure out how to spend less than our depreciation charge and keep our businesses competitive."

See EBITDA, Accounting Earnings vs Economic Earnings, Owner Earnings.

☔ Climate Change & Insurance — The Pascal's Wager

The Rebuttal: To a proxy proposal requesting a climate change risk report. Buffett's view: climate change likely poses a major problem for the planet, but NOT a financial problem for Berkshire's insurance operations — because insurance reprices annually. The Logic: "Up to now, climate change has not produced more frequent nor more costly hurricanes. As a consequence, U.S. super-cat rates have fallen steadily in recent years." If climate change worsens, "the likely — though far from certain — effect on Berkshire's insurance business would be to make it larger and more profitable." The Noah's Law Extension: Pascal's Wager logic applied to climate policy: "If there is only a 1% chance the planet is heading toward a truly major disaster and delay means passing a point of no return, inaction now is foolhardy." The True Risk: The one risk Berkshire cannot hedge: "a 'successful' cyber, biological, nuclear or chemical attack on the United States."

💰 2015 Shareholder Letter: "The Luckiest Crop in History"

"For 240 years it's been a terrible mistake to bet against America, and now is no time to start. America's golden goose of commerce and innovation will continue to lay more and larger eggs." — Warren Buffett, 2015

🎭 The Narrative Context

The 2015 letter is written at a peculiar moment: Berkshire is 51 years old, and Buffett — age 85 — is writing in the middle of a U.S. presidential primary cycle defined by economic anxiety. The letter is part anniversary reflection, part philosophical counterattack against pessimism. The financial substance is quietly enormous — the Precision Castparts acquisition at $32B+, a 13th consecutive underwriting profit, and BNSF's dramatic operational turnaround after 2014's service failures — but Buffett uses most of the letter's philosophical bandwidth not on these achievements, but on a sustained argument about why America's economic machine continues to work.

The letter also represents a methodological evolution: Buffett explicitly changes the intrinsic value calculation to include insurance underwriting income, marking the first time in Berkshire's history that underwriting results are treated as stable business earnings rather than volatile catastrophe-dependent windfalls. This is a signal that the insurance operation has matured into a predictable economic franchise. The final section — the announcement of a live webcast of the annual meeting — is framed in characteristically humorous terms, but the subtext is unmistakable: at 85 and 91, Berkshire is beginning to make institutional preparations for the long transition ahead.

💡 Philosophical Gems

The Mechanism: Why Book Value Has Become Irrelevant

The Logic: GAAP requires writing down controlled business "losers" but forbids writing up "winners." Over decades, this asymmetry accumulates into a structural gap between book value and intrinsic value. For early Berkshire — a portfolio of marketable securities — book was a useful proxy. For modern Berkshire — largely controlled businesses — book is a significant understatement. The Discipline: This asymmetry is why Berkshire would be "delighted" to repurchase at 120% of book — not because it's cheap in absolute terms, but because even at that price, the repurchase instantly increases per-share intrinsic value. The Quote: "We've had some winners — a few of them very big — but have not written those up by a penny."

See Intrinsic Value, Share Repurchase Policy.

The Productivity Gospel: Agriculture, Railroads, and Insurance

The Argument: Every major American industry has delivered massive productivity gains that initially seem to threaten workers but ultimately deliver vastly better living standards at lower costs. Buffett traces the transformation of farming (11M workers in 1900 → 3M today; output 5x), railroads (1.35M workers in 1947 → 187,000 today; tonnage nearly 3x), and auto insurance (agency model with 40¢ cost per premium dollar → GEICO's 14.7% expense ratio). The Moral: The gains must be shared. Safety nets — specifically an expanded Earned Income Tax Credit — are the right instrument. Prohibiting efficiency gains would have been catastrophic: "We would not have anything close to the America we now know had we stifled those improvements in productivity." The Quote: "It was fortunate that horses couldn't vote." (On the agricultural revolution's displacement of draft animals.)

See The American Tailwind, GEICO, BNSF.

The GAAP Amortization Fraud (Partial)

The Distinction: Amortization of software is real (the software degrades). Amortization of "customer relationships" from purchase accounting is a fiction that flows from accounting rules, not economics. Berkshire's $1.1B in GAAP amortization contains approximately $880M of non-real charges. The Crescendo: The stock-based compensation critique is the sharpest in any Berkshire letter. "The very name says it all: 'compensation.' If compensation isn't an expense, what is it?" Analysts who suppress this line item are complicit in deceiving investors — either from ignorance, fear of losing management access, or cynicism. The Quote: "When CEOs or investment bankers tout pre-depreciation figures such as EBITDA as a valuation guide, watch their noses lengthen while they speak."

See EBITDA, Accounting Earnings vs Economic Earnings, Stock Option Critique.

The Capital Allocation Flexibility Theorem

The Insight: Berkshire's willingness to allocate capital to both controlled businesses and passive minority stakes gives it a "significant edge" over companies that limit themselves to controlling acquisitions. Most acquirers must own 100% to justify the management attention. Berkshire will take either. The Quote: "Woody Allen once explained that the advantage of being bi-sexual is that it doubles your chance of finding a date on Saturday night. In like manner — well, not exactly like manner — our appetite for either operating businesses or passive investments doubles our chances of finding sensible uses for Berkshire's endless gusher of cash."

See Capital Allocation, Buyer of Choice.

The Managed vs. Natural Culture: Decentralization as Core

The Philosophy: Buffett contrasts Berkshire's model explicitly with 3G Capital's. 3G extracts inefficiency through rapid, large-scale staff reductions — a legitimate and value-creating approach. Berkshire extracts efficiency by acquiring businesses that were already run efficiently and then "creating an environment in which these CEOs can maximize both their managerial effectiveness and the pleasure they derive from their jobs." The Mungerism: "If you want to guarantee yourself a lifetime of misery, be sure to marry someone with the intent of changing their behavior." — the philosophical anchor for Berkshire's non-interference model. The Implication: "We will continue to operate with extreme — indeed, almost unheard of — decentralization at Berkshire." This is not laziness; it is a deliberate theory of value creation.

"For 240 years it's been a terrible mistake to bet against America, and now is no time to start."
"The babies being born in America today are the luckiest crop in history."
"When CEOs or investment bankers tout pre-depreciation figures such as EBITDA as a valuation guide, watch their noses lengthen while they speak."
"If compensation isn't an expense, what is it? And, if real and recurring expenses don't belong in the calculation of earnings, where in the world do they belong?"
"It's better to have a partial interest in the Hope Diamond than to own all of a rhinestone."
"Call this Noah's Law: If an ark may be essential for survival, begin building it today, no matter how cloudless the skies appear."
"The price of achieving ever-increasing prosperity for the great majority of Americans should not be penury for the unfortunate."
"The most important development at Berkshire during 2015 was not financial, though it led to better earnings." (On BNSF's service turnaround.)

🔗 Evolutionary Links

[!TIP] The 2015 letter is the clearest expression of Buffett's philosophy at institutional scale: a 51-year compounding machine whose intrinsic value dwarfs its book value, whose underwriting income is now stable enough to count as business earnings, and whose model of radical decentralization is explicitly contrasted with the extraction-and-efficiency approach of 3G Capital. The Precision Castparts acquisition — the largest in Berkshire's history — is announced almost as an aside. The true centerpiece is the productivity essay: a sustained, data-rich argument that American economic growth, even at a "disappointing" 2%, delivers staggering generational wealth. This is Buffett at his most optimistic, his most pedagogical, and his most honest about the dislocations that progress requires.
