## What Are the Key Differences Between Gallagher and Marsh D&O Insurance?

### Going-Public Specialist vs Every Organization Type

Gallagher markets D&O placement and advice to SPACs around IPO and de-SPAC and to companies listing by IPO or direct listing, and benchmarks Side-A-only towers (coverage just for individuals) for them. [1](https://www.ajg.com/insurance/executive-and-financial-risk-insurance/ "Executive and Financial Risk Insurance") Marsh's financial and professional liability practice covers public, private and nonprofit companies, and Marsh McLennan Agency (MMA) handles middle-market clients. It notes public-company directors face more securities suits, while private and nonprofit boards more often face employment claims. [2](https://www.marsh.com/en/services/financial-professional-liability/expertise/directors-and-officers-liability.html "Directors and Officers Liability (D&O)") [3](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Expert Executive and Professional Liability Insurance") Choose Gallagher if you're a SPAC or planning an IPO or direct listing; choose Marsh if you're a private, nonprofit or middle-market company whose main D&O risk is employment claims. [1](https://www.ajg.com/insurance/executive-and-financial-risk-insurance/ "Executive and Financial Risk Insurance") [2](https://www.marsh.com/en/services/financial-professional-liability/expertise/directors-and-officers-liability.html "Directors and Officers Liability (D&O)")

### ESG and Side C

Marsh lists the ESG topics drawing scrutiny: carbon emissions, renewable-energy use, labor practices, board diversity and executive pay. It explains that Side C (cover for the company itself) is usually limited to securities claims for public companies. [2](https://www.marsh.com/en/services/financial-professional-liability/expertise/directors-and-officers-liability.html "Directors and Officers Liability (D&O)") Gallagher's page doesn't address ESG.
