D&O insurance can help pay covered defense costs and losses from claims against company leaders over management decisions. If your organization has a board or executives, check whether the company itself is insured and whether legal bills reduce the limit.

Berkshire Hathaway Specialty Insurance names large commercial and financial firms as target accounts and presents an Executive First D&O product. The adviser conversation can establish which carrier and policy fit an organization, while BHSI’s stated target segment offers a specific appetite checkpoint; neither description determines the final quoted terms.
