Slightly lower profit, steady margin.

HCC was Tokio Marine's largest acquisition: a $7.5 billion deal4. It brought specialty underwriting capabilities across many small lines, which are hard to replicate because each requires its own expertise.

HCC's business-unit profit of ¥122.1 billion5 made it the second-largest American contributor after Delphi. It writes many small specialist lines, each with its own underwriters, which is why the business is harder to copy than a single large line.

The measure is its combined ratio. Staying below 90% is the evidence that the $7.5 billion bought a lasting advantage.

Moat trajectory: Holding steady

Combined ratio steady at about 88%.
