Key Differences in D&O Insurance
Who the Page Is Written For
Marsh's D&O page addresses buyers directly, describing risk categories and coverage sides for public, private and nonprofit companies. 5 Relm's page instead speaks to brokers, framing itself as a market they can place client coverage through rather than content a founder reads to self-quote. 9
Sector Framing Versus Organization-Type Framing
Marsh splits eligibility by organization type, saying public companies more often face securities suits and private or nonprofit companies more often face employment-practices claims. 5 Relm instead names specific emerging sectors:
Relm targets companies in disruptive or fast-changing sectors, naming Web3 founders, biotechnology leaders and AI pioneers as examples, and says any company with a board benefits, with startups especially needing it to attract executives. 9Company-reported. Financial Lines page framing; not a guarantee of eligibility for a particular company.
An Emerging Risk Category
Marsh names a specific added pressure on directors and officers, pointing to ESG-related scrutiny over board diversity and executive pay. 5 Relm's reviewed page doesn't address ESG-related scrutiny; its coverage description centers on shareholder, regulator, competitor and employee claims generally. 9
What to Confirm in D&O Insurance Quotes
- Ask Marsh which entity issues the policy; the reviewed pages don't name one. 5
- If you don't already work with a broker, ask whether Relm's capacity is reachable directly or only through a broker relationship. 9
- If board diversity or executive-pay scrutiny is a concern for your company, ask Marsh how that factors into the placement. 5
- If your company operates in Web3, biotech or AI, ask Relm how sector-specific risk changes underwriting compared with Marsh's organization-type framing. 9
