Bond series on this file
What they claim to write
Series A
License & Permit
Most regulated businesses post a license or permit bond before a state will issue or renew the license. The bond guarantees compliance with the statute — it is not insurance for the principal.
Series B
Contract / Performance
Construction and public-works contracts ask the contractor to guarantee the bid, the work, and the subcontractors. These are underwritten on financials and experience, not just a credit score.
Series C
Commercial
Commercial surety covers the bonds that sit beside a license or a jobsite: employee dishonesty, public official, lost-instrument, and a long tail of miscellaneous forms.
Series D
Court / Judicial
Courts require bonds so a judgment, estate, or injunction has a solvent backstop. These are often collateral-heavy and time-sensitive.
