Key Differences in D&O Insurance
Terms that matter before a claim
Liberty Mutual describes ProShield as one policy combining multiple management-liability coverages. Marsh explains D&O through Side A protection for individuals, Side B reimbursement when the organization indemnifies them, and Side C entity protection that is generally limited to securities claims for public companies but broader for private and nonprofits. Buyers should check how a ProShield package expresses these parts against Marsh’s proposed tower, especially the scope of Side C. 3 8
Placement and coverage structure
Marsh places D&O for public, private and nonprofit organizations and discusses distinct exposure patterns: securities litigation for public companies and more employment-related allegations for private and nonprofit organizations. Liberty Mutual identifies private-company and not-for-profit ProShield options. A public company should not assume the overview establishes a ProShield option; ask which product and wording are available for its status. 8 8 3
What to Confirm in D&O Insurance Quotes
- Which ProShield option, if any, is available to a public company? How broad is Side C for this organization under each quote? Compare securities, employment-related and cyber allegations, plus limits and retentions.
