Scored by the financial-sector model

BERKLEY W R CORP is a insurer, scored by a separate financial-sector model — not the operating Moat Score you’ll see on other companies. A bank or insurer is a balance-sheet business the margin-and-ROIC lens doesn’t fit, so it’s read through the components below instead. The two models are calibrated differently and are not comparable: a financial-sector score is never ranked against, sorted with, or averaged into an operating Moat Score. How the models work.

Insider activity

Form 4 reports mix P/S market or private transactions with compensation-plan mechanics. Activity casually described as “insider selling” can include compensation mechanics; awards, tax withholding, and option exercises are shown by their exact filed class here, never collapsed into “Bought” or “Sold.”

These are disclosed filing facts and arithmetic aggregates, not a signal or verdict.

This machine-readable surface covers SEC ownership filings from 2003; it does not represent earlier paper-era records.

Records still being gathered — partial as of retrieval Sep 17, 2026.

2 filings were skipped because the SEC primary document returned 404; the omission is disclosed and aggregates are withheld.

Among the rows shown, A/F/M acquisition, payment or withholding, and exercise or conversion rows outnumber S sale rows (8 versus 0). The filing codes alone do not establish that every such row arose from a compensation plan.

Trailing-12-month totals and the 90-day cluster result are withheld because this issuer walk is incomplete.

What the financial-sector model scores (insurer)

96

Median ROE 15.8% on average equity, above the 10% hurdle in 89% of 9 years.

79

Q3 scored 2 evidenced ratios equally.

82

Profitable in 100% of 10 years, ROE steady.

Not scored for this company

Canonical split-adjusted share history is incomplete; no book-value trend claim is made.
Net interest economics apply to banks and lenders; not part of the carrier model.

Scored 4 of 5 applicable components (underwriting carrier model); weights renormalized over the scored set.

Fundamentals

The 15-year revenue, margin, and ROIC series is built for the operating model’s lens and isn’t published for banks and insurers — a balance-sheet business is read through the components above, not through operating-company margins.

Append-only — readings are added, never rewritten. Only readings on the same methodology version (moat-index-financials@1.0.0) are comparable; a change across versions is a scoring change, not a company event.

Scored from primary SEC filings via the public financial-sector methodology. Educational only — not a recommendation to buy or sell WRB. See the disclaimer.
