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
- Underwriting discipline and the float. What decides it: whether the combined ratio stays below 100% so the policies make money on their own, how large the float is against equity, and what that float earns once it is invested. 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?
- Claims run 55% of premiums, with underwriting costs on top. Book value per share, the measure Berkshire is judged on, has compounded about 27% a year across the record. The float runs about 1.6× equity, the leverage that magnifies both the underwriting and the investing. Whether the discipline holds through a soft market, and how the float is invested, are what the 10-K decides.
Every line is arithmetic on the company's filings, shown in full in the sections below.

The year, in the company's words
the filing →Verbatim from the 10-K's management discussion. Each sentence is shown only because its subject, direction, and stated figures check out against the filed numbers on this page. The words are the company's; the arithmetic is the record's.
- Net income+21.4%
“Net income was $503.6 million for the year ended December 31, 2025 compared to $414.8 million for the year ended December 31, 2024, an increase of $88.8 million, or 21.4%. The increase in net income in 2025 over 2024 was primarily due to a combination of continued profitable growth and strong investing results including higher investment income and higher returns on equity investments.”
✓ figure matches the filed record - Net premiums earned+16.7%
“Net earned premiums were $1.6 billion for the year ended December 31, 2025 compared to $1.4 billion for the year ended December 31, 2024, an increase of $225.4 million, or 16.7% due primarily to continued earning of premium from prior-period growth in gross written premiums and higher net retention levels.”

Owner’s Scorecard
Is it a good business?
- Loss ratio 57%Claims share of premiumsClaims incurred $891M ÷ premiums earned $1.6B
What this means
Claims as a share of premiums (the expense side was not cleanly tagged, so we show the loss ratio alone rather than a full combined ratio). Lower is better; the rest of underwriting cost sits on top of this.
- Return on equity 26%StrongNet income $504M ÷ equity $2.0BIndustry peers: median 10%
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.
The float
- Float $3.1B1.6× equityNet reserves + unearned premiums − prepaid reinsurance − receivables − DAC = $3.1B
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. The larger it is against equity, the more that leverage works, for better or worse.
- Investment income $192M6.2% on the floatNet investment income $192M, 6.2% 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 cost and the reserves
- Not enough data
What this means
Needs the full float arithmetic and a cleanly tagged underwriting total; a partial figure would mislead.
- Reserve development −$63MPast promises heldPrior-year development, FY2025: favorable (reserves released) · record: 10 favorable, 0 unfavorable of 10
What this means
Each year an insurer restates what its old accident years actually cost. Persistent favorable development means management reserved honestly and released the cushion; persistent unfavorable development means past profits were overstated by under-reserving — the industry's chronic sin, and the single most tell-tale line an owner can read. Signed as the company files it: negative favorable, positive unfavorable.

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 | Michael Kehoe | $3.0M | $3.4M | $405M |
| 2022 | Michael Kehoe | $3.8M | $4.1M | $555M |
| 2023 | Michael Kehoe | $5.2M | $6.1M | $857M |
| 2024 | Michael Kehoe | $6.8M | $8.2M | $970M |
| 2025 | Michael Kehoe | $7.4M | $6.4M | $1.0B |
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$18M
The slice of the business handed to employees in shares in fiscal 2025, 1.0% of revenue, equal to 2.8% 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.

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 Kinsale Capital Group Inc.’s record justifies.
Tangible book / share, delivered28%/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.
Enter a price above to run it.
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.
A dated snapshot of the price you typed, the assumptions you set, and what the page showed for them. A snapshot is never edited after it is saved. Your notebook is yours alone — the commitment states what is stored and what we will never do.
Tangible book $2.0B on 23M shares, a 18% 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.
