W. R. Berkley Corporation (WRB)

Specialty property casualty insurer, parent staff counted. Read October 19, 2026 from the annual report for the period ending December 31, 2025, filed February 27, 2026. Ranked 56 of the 101 Financial Services companies read so far, by the share within reach now.

An insurer whose filing counts 8,678 employees at its subsidiaries and 126 at the parent, so the carriers' pattern leads and the counted parent staff take management of companies.

The figures on this page come from the company's own annual report and from BLS staffing patterns for its industries, never from a roster. They are estimates with a stated method. Nothing here says what the company will do: within reach is not a forecast of jobs lost or of savings.

What follows from the reading

Share of working time within reach of AI, on the long-run pace at four in five: 38% now, 59% at the end of 2027, 68% at the end of 2028, 71% at the end of 2030. By the patterns, the work is about 71% desk work, 25% people work and 4% body work. These are the site's industry estimates weighted by the shares below: estimates with a stated method and range, not a forecast of what the company will do. By the same patterns, at the end of 2028 about 29% of the working time stays with people (conversation, in-person and hands-on work), 61% becomes checking a model's work and 6% could be handed over with lighter checks, from the industries' own figures, not the company's roles.
