THREE small business insurance: coverage, issuer and buying routes

What Is Directors and Officers Insurance?
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. 7,8,9
Key Differences in D&O Insurance
Specific features in the reviewed records
THREE lists D&O among coverage categories in its combined Business Owners Policy, while Liberty Mutual describes ProShield as a package combining management-liability coverages. The product pages do not establish that every category appears in every quote. Small businesses should check the insurance summary to confirm that D&O is actually selected and identify its limit, alongside ProShield’s included sections. 6 3
How each route is structured
THREE’s linked sample policy names Berkshire Hathaway Direct Insurance Company in its declarations, while Liberty Mutual’s overview describes ProShield without naming the issuer for a particular proposal. The sample identifies an example carrier, not necessarily the buyer’s issued policy. Verify the writing company on both quotes before assessing form wording and claims contacts. 5 3
What to Confirm in D&O Insurance Quotes
- Does the THREE quote include D&O as selected coverage, and what limit and deductible does its insurance summary show? Which insurer and wording apply to ProShield? Compare Side A/B/C protection, inquiry costs and package aggregates.

The inspected sources report separate measures: NerdWallet’s 4.0/5 editorial rating is excluded from the source-rating average; Trustpilot displayed 2.5/5 from five user posts and BBB displayed 4.8/5 from 265 reviews. Trustpilot and BBB include different purchase, service and agent/intermediary interactions, not a verified common policyholder cohort. BBB separately lists complaints. Any source-rating average weights eligible platforms equally and is not a pooled, representative customer-experience estimate or a claims-quality measure.[4][3][1][2]

It does not establish the issuing insurer for an individual quote, exact state or provincial availability, the policy form, complete exclusions, or terms offered to a particular buyer; confirm those in the quote and policy documents. | THREE presents Directors and Officers as a component of its combined Business Owners Policy rather than identifying it as a separate standalone policy on the reviewed product page. 6Company-reported.
