The business in brief
read the 10-K →What this business is and what moves its needle, from its own SEC filings.
- What moves the needle
- The spread on the float and the growth in book value. What decides it: the gap between what the invested reserves earn and what is credited to policyholders, the mortality and fee margins on top, and the scale of the float against equity. Benefits exceed premiums by design, so a P&C combined ratio is the wrong lens; the risks are interest rates and reserve adequacy. On its own account, the filing leans hardest on pricing power & competition, set against the numbers in what the filing emphasizes, below.
- Is it a good business?
- A life insurer is read on the spread it earns on a large float and the growth in book value, not a combined ratio: benefits exceed premiums by design, since claims fall due decades after the premium and are funded by the investment income on accumulated reserves. Book value per share, the measure Berkshire is judged on, has compounded about 6% a year across the record. The float runs about 3.4× equity, the leverage that magnifies the spread. Whether the spread holds as rates move, and whether the reserves prove adequate, are what the 10-K decides, not an earnings multiple.
Every line is arithmetic on the company's filings, shown in full in the sections below.

Is it a good business?
- Below the cost of equityNet income $739M ÷ equity $11.1BIndustry peers: median 13%
What this means
What it earns on shareholders' capital, the underwriting result plus what the float earns invested. Durably above the ~10% cost of equity is what compounds book value.
- Investment income $2.0B5.3% on the floatNet investment income $2.0B, 5.3% on the float
What this means
What the float and capital earned this year. This is the second engine: an insurer that breaks even on underwriting still wins if the float is large and invested well.
The float and book value
- Float (reserves) $38.0B3.4× equityLoss and claim reserves $38.0B, 3.4× equity
What this means
Money held against future claims and invested in the meantime. Buffett's insight was that good underwriting makes this float cost less than nothing, a pool of other people's money the owners earn on. Measured here from loss and claim reserves only; it excludes unearned premiums and funds held, so the true float is somewhat larger than shown. The larger it is against equity, the more that leverage works, for better or worse.
- the compounding scoreboardEquity $11.1B ÷ 173M shares
What this means
A life insurer is judged the way Berkshire is, by the growth in book value per share over the years as the spread on the float and the mortality and fee margins compound into equity. This is the level today; the record below shows whether it has grown. Note that reported book value swings with interest rates, which mark the bond portfolio up and down through other comprehensive income.
Does AI threaten the moat?
Low contestabilityThe moat is physical, regulated or balance-sheet-funded, the kind AI cuts costs within but does not contest.
In its own filing Named as a competitive risk
Its FY2025 10-K names artificial intelligence as a competitive threat.
“Our use of artificial intelligence technology, as well as changes in artificial intelligence laws and regulations, could lead to regulatory noncompliance, operational risk, and competitive challenges.”
AI is unlikely to contest a moat that is physical, regulated or balance-sheet-funded; here it reads more as a cost tool than a threat, and the company is using it that way.
Read from the filing's own risk factors, paired with the industry's structure under its SIC code; the durability is read above, the price below.

Management, ownership & pay
read the proxy →From the proxy: how much of the business the people running it own, and how they are paid, beside what the business earned for its owners in the same years.
| Fiscal year | Chief executive | Pay, as filed | “Actually paid” | Owner earnings |
|---|---|---|---|---|
| 2021 | Mr. McKenney | $9.3M | $11.2M | $1.3B |
| 2022 | Mr. McKenney | $9.6M | $24.1M | $1.3B |
| 2023 | Mr. McKenney | $19.7M | $22.0M | $1.1B |
| 2024 | Mr. McKenney | $18.4M | $27.0M | $1.4B |
| 2025 | Mr. McKenney | $19.4M | $21.4M | $555M |
Both pay figures are the company’s own, from the pay-versus-performance table its proxy statement files. “As filed” is the Summary Compensation Table total: salary, bonus, and equity awards at their value on the day of grant. “Actually paid” is the SEC’s prescribed recalculation, which re-marks those equity awards to what they became as they vested; it can swing far above or below the filed figure in either direction, and negative years occur. Owner earnings are the whole business's, from the record above, for the same fiscal years.
- Insider ownership<1%
The stake all directors and executive officers hold together, per the 2026 proxy: skin in the game, the first thing Munger reads.
- Stock-based compensation$25M
The slice of the business handed to employees in shares this year, 0% of revenue, equal to 2% of operating profit. Buffett's oldest accounting fight: this is compensation, compensation is an expense, real whether or not the headline earnings admit it. One trap: the cash-flow statement adds SBC back, so the operating cash, and the owner earnings drawn from it, are flattered by exactly this amount; counted as the cost it is, what an owner keeps is lower.
Peers, Insurance — Life & Health
The same industry, side by side on the spread-and-book-value lens. Each figure is a through-cycle median, so a peak or trough year can’t distort it; the group median at the foot is the line to read each against.

The price
What a price has to assume.
What the price implies
price / tangible bookAn insurer is worth a multiple of its tangible book value, and the multiple it deserves is set by the return it earns on that book. Type today’s price; we show what you would be paying against what Unum Group’s record justifies.
$
The assumptions
Tangible book / share, delivered10%/yr’20→’25
The justified multiple is (return on tangible equity − growth) ÷ (cost of equity − growth). An insurer earning exactly its cost of equity is worth about one times tangible book; the premium above that prices each point of durable excess return. A higher cost of equity lowers the justified multiple for an insurer.

Graham’s price gate—
Graham applied the same standards to financial enterprises (Intelligent Investor ch.14): the 15× multiple cap on averaged earnings, and P/E times price-to-book at most 22.5. The gate marks the bargain-hunter’s floor, not a verdict.

Tangible book $10.5B on 160M shares, a 11% normalized return on it. The dials set the multiple such a return would justify; your price sets the multiple you are paying. It assumes the insurer keeps earning that return; an underwriting cycle, a reserve shortfall or a bad year on the float changes it, which is what the record and the 10-K are for.
