Key Differences in Surety Bonds

Who issues the bond

Chubb says it underwrites surety bonds directly; Aon acts as a broker or adviser for surety placements. A direct underwriter may simplify the issuer relationship, while the broker route can help arrange markets. Ask who issues the bond and who receives indemnity. 3 7

If you need a one-time permit bond, ask about Chubb’s transactional platform; for a construction program, compare the capacity available through Aon. 3 7
