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.

Its team describes coordinating pre- and post-IPO D&O with lines such as representations and warranties, E&O, cyber and tax. MMA describes D&O for corporate executives, board members and organizations, without a transaction-specific process in its claim. Companies nearing a listing should ask MMA how it would structure each transaction stage. [3](https://www.ajg.com/insurance/executive-and-financial-risk-insurance/ "Executive and Financial Risk Insurance") [8](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") ### Claims advocacy and program design Gallagher says its practice has in-house attorneys on a dedicated claims-advocacy team and uses benchmarking, including review of Side-A-only limits, to shape programs. MMA describes D&O defense costs for civil and criminal actions and investigations, and directs buyers to an adviser. If claim support or Side A capacity is central, ask both teams how they would coordinate with insurers and counsel after notice.
