The business
What it sells, where the money comes from, the kind of company it is.
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?
- It underwrites at a profit, about a 94% combined ratio (it keeps roughly 6% of premiums before investing the float). Book value per share, the measure Berkshire is judged on, has compounded about 10% a year across the record. The float runs about 0.7× 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.

Owner’s Scorecard
Is it a good business?
- Combined ratio ≈ 97%Roughly breakevenTotal benefits, losses and expenses $9.7B ÷ premiums earned $10.0BIndustry peers: median 99%
What this means
The heart of a property-casualty insurer: claims and costs as a share of premiums. Below 100% means it is paid to hold the float, the gold standard; above 100% means it loses money on the policies and must make it back on investments. Approximate here, taken from the filer's total benefits, losses and expenses over premiums, so it can sit a point or two off the company's headline figure; a number held below 100% across cycles is the mark of a disciplined underwriter, the rarest thing in the business.
- Return on equity 15%StrongNet income $2.4B ÷ equity $15.9BIndustry 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 $3.8B0.2× equityPolicy benefits + deposits + guarantees − recoverables − DAC − receivables = $3.8B
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. Basis note: recoverables deduction unavailable. The larger it is against equity, the more that leverage works, for better or worse.
- Investment income $1.2B31.0% on the floatNet investment income $1.2B, 31.0% 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
- Cost of float −2.5% · FY2023Last reported FY2023FY2023, the most recent year reported: underwriting profit $221M ÷ that year's float $9.0B
What this means
Buffett's own yardstick — the underwriting result as the price of holding the float — read at the most recent year the filing data carries it, both legs from that same year, and named rather than passed off as current.
- Reserve development −$196MPast promises heldPrior-year development, FY2025: favorable (reserves released) · record: 10 favorable, 0 unfavorable of 10In the filing’s words
“We experienced $ 196 million of favorable development on prior accident years including $ 130 million of favorable development in commercial lines, $ 4 million of favorable development in personal lines and $ 19 million of favorable development in excess and surplus lines during 2025.”
✓ the narrated $ 196 million ties the filed figure · the words are the company’sWhat 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 | Pay, as filed | “Actually paid” | Owner earnings |
|---|---|---|---|
| 2021 | $6.5M | $9.6M | $2.0B |
| 2022 | $7.6M | $4.7M | $2.0B |
| 2023 | $8.4M | $6.7M | $2.0B |
| 2024 | $8.8M | $12.7M | $2.6B |
| 2024 | $9.9M | $16.2M | $2.6B |
| 2025 | $5.9M | $7.9M | $3.1B |
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.

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 Cincinnati Financial Corporation’s record justifies.
Tangible book / share, delivered8%/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 $16.7B on 153M shares, a 14% 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.
