National Indemnity

• The Bottom Line: National Indemnity is the financial engine of Berkshire Hathaway, a giant insurance company that turns customer premiums into a vast, low-cost mountain of cash for Warren Buffett to invest.
• Key Takeaways:
• What it is: The largest and most important of Berkshire Hathaway's insurance subsidiaries, specializing in large-scale commercial insurance and reinsurance.
• Why it matters: It generates enormous amounts of “insurance_float“—the cash collected from premiums that has not yet been paid out in claims. This float is the primary fuel for Berkshire's legendary investment portfolio.
• How to use it: Understanding National Indemnity is a masterclass in identifying businesses with a powerful, self-funding competitive moat.

Imagine a special kind of bank. With a normal bank, you deposit your money, and the bank pays you a small amount of interest for the privilege of using it. Now, imagine a bank where you deposit your money, and not only do you not get paid interest, but there's a good chance the bank will get to keep your deposit forever. And on top of that, this “bank” can use your deposited money for decades to invest for its own profit. That, in a nutshell, is the magic of National Indemnity Company (often called NICO). While most of us are familiar with Berkshire Hathaway's consumer-facing insurance company, GEICO, with its friendly gecko mascot, National Indemnity is its older, bigger, and far more powerful sibling. It doesn't sell car insurance to you and me. Instead, it deals in the world of massive, complex, and sometimes unusual risks. It provides insurance for other insurance companies (a business called “reinsurance”) and writes enormous policies for corporations, covering everything from potential hurricane damage to a satellite launch failure. Founded in Omaha, Nebraska, in 1940, it was one of Warren Buffett's earliest and most pivotal acquisitions back in 1967. He saw something in this small, well-run insurer that others missed: the power of its float. He understood that by collecting premiums upfront and paying claims much later, the company would hold a massive, revolving pool of cash. This cash didn't belong to Berkshire, but it could be invested for Berkshire's benefit. This simple but profound insight turned a humble Omaha insurer into the cornerstone of one of the world's most successful conglomerates. National Indemnity, led for decades by the brilliant insurance mind of Ajit Jain, became a machine for generating investable capital, which Buffett then allocated with legendary skill into stocks like Coca-Cola and Apple, and entire businesses like the BNSF Railway.

“Our property/casualty (P/C) insurance business has been the engine propelling Berkshire’s growth since 1967… The P/C business has been a marvel for Berkshire. We have now operated at an underwriting profit for 14 consecutive years, our float figure has grown from $19 million to $114.5 billion, and we have access to these funds at a cost below zero. It’s like having a bank that pays you to hold its money.” - Warren Buffett, 2017 Letter to Shareholders

Essentially, National Indemnity is the heart of Berkshire Hathaway. It pumps the financial lifeblood—the float—that allows the brain (Buffett and his team) to make the investments that have created staggering wealth for shareholders over the last half-century.

For a value investor, the story of National Indemnity isn't just a piece of corporate history; it's a foundational text. It perfectly illustrates several core principles of the value investing philosophy. 1. The Ultimate “Float” Generator: The most crucial concept is insurance_float. Most companies finance their operations with debt (which costs interest) or equity (which dilutes ownership). National Indemnity finances Berkshire's growth with its float. As long as NICO operates at an underwriting profit (meaning the premiums it collects are greater than the claims and expenses it pays out), this capital is better than free. It's as if someone paid you to take out a loan. A value investor constantly searches for businesses with such powerful economic advantages, and NICO is the gold standard. 2. Underwriting Discipline as a Margin of Safety: The insurance business is tempting. It's easy to grow by simply lowering prices to attract more customers and collect more premiums. This, however, is a recipe for disaster, as future claims will eventually overwhelm the cheap premiums. National Indemnity, under Ajit Jain's leadership, is famous for its fanatical underwriting discipline. They would rather walk away from a deal than write an unprofitable policy. This discipline is the insurance equivalent of Benjamin Graham's margin of safety. They insist on a buffer between the price they receive (the premium) and the estimated cost (the future claims). This protects the float and ensures it remains a low-cost source of funds. 3. A Model of a Durable Competitive Advantage (Moat): Why can National Indemnity do what others can't?

• Immense Scale and Capital: It has a fortress-like balance sheet. This allows it to take on risks so large that almost no other company in the world can compete. When a massive, unique risk needs coverage, NICO is one of the very few phone calls to make.
• Reputation: For decades, it has built a reputation for paying valid claims, no matter how large. This trust is an invaluable asset.
• Rational Management: Its leadership is focused on long-term profitability, not short-term market share or quarterly earnings.

4. The Power of Capital Allocation: Generating the float is only half the battle. The other half is investing it wisely. The genius of the Berkshire model is the perfect marriage of a world-class float generator (NICO) with a world-class capital allocator (Warren Buffett). A value investor learns from this that it's not enough to find a great business; you must also ensure its management is skilled at reinvesting the profits in a way that creates even more value. Understanding National Indemnity teaches a value investor to look beneath the surface. It’s a lesson in appreciating the boring, unglamorous machinery of a business that can produce spectacular long-term results.

You can't buy shares in National Indemnity directly, but you can apply its lessons to your own investment analysis. The goal is to find other businesses that share its powerful economic characteristics.

1. Step 1: Look Beyond the Product, Analyze the Business Model.

Instead of just asking “What does this company sell?” ask “How does this company fund its growth?”. Look for businesses that get paid by their customers upfront, long before they have to deliver a product or service. This creates a source of “float.”

1. Step 2: Identify Non-Obvious Sources of Float.

While insurance is the classic example, other industries have similar structures:

• Subscription services: Companies like Amazon (with Prime memberships) or Costco collect fees upfront for future benefits.
• Gift cards and stored value: Starbucks holds billions of dollars in customer funds on its gift cards and mobile app.
• Software and maintenance contracts: Companies that get paid annually for software licenses or service contracts that are delivered over the course of the year.
• Customer deposits: Some manufacturing or travel businesses require large customer deposits long before the final product is delivered.

1. Step 3: Evaluate the “Cost” of the Float.

The key question is whether this float is cheap or expensive. For an insurer, the metric is the combined_ratio (total claims and expenses divided by premiums collected).

• Combined Ratio < 100%: The insurer is making an underwriting profit. The float is better than free. This is the NICO ideal.
• Combined Ratio > 100%: The insurer has an underwriting loss. The float has a cost. For example, a ratio of 103% means the float costs 3% per year. This might still be cheaper than debt, but it's not free.

For non-insurance businesses, ask if the business generating the float is profitable on its own, or if it's a loss-leader.

1. Step 4: Assess Management's Capital Allocation Skill.

A company can have a wonderful source of float, but if management wastes it on foolish acquisitions or unproductive projects, it's worthless to shareholders. Look for a management team with a clear, rational, and successful track record of reinvesting the company's cash to generate high rates of return. This is the Buffett side of the equation.

Let's compare two hypothetical insurance companies through the NICO lens.

• RockSolid Reinsurance: A disciplined company that prioritizes profitability.
• GambleSure Insurance: A reckless company that chases growth at any cost.

^ Characteristic ^ RockSolid Reinsurance (The NICO Way) ^ GambleSure Insurance (The Wrong Way) ^

This example shows that just having float isn't enough. It must be profitable float, and it must be managed by skilled capital allocators. This is the central lesson from National Indemnity.

Analyzing a business through the “National Indemnity lens” is a powerful tool, but it has its own strengths and weaknesses.

• Focus on Economic Reality: It forces you to look past surface-level metrics and understand the true economic engine of a company.
• Highlights Capital Efficiency: It reveals companies that have a powerful, built-in funding advantage, which is a major component of a deep moat.
• Long-Term Perspective: This type of analysis naturally favors businesses built for the long haul, aligning perfectly with the value investing temperament.

• True NICO-Clones are Extremely Rare: The combination of massive scale, underwriting discipline, and brilliant capital allocation found at Berkshire is almost unique. Investors may be tempted to see “float” where only a simple prepayment exists.
• Underwriting Risk is Hidden: For insurance companies, the biggest risks are in the policies they've written. A single “mega-catastrophe” (like a massive hurricane or earthquake) could cause catastrophic losses, proving that the float was not free at all. Assessing this risk from the outside is incredibly difficult.
• Complexity: Properly analyzing an insurance company's financials and underwriting quality requires a deep circle_of_competence. It's far more complex than analyzing a simple manufacturing or retail business.
