11.4 Surety Bonds
Key Takeaways
- A surety bond is a three-party agreement: the Principal (who performs), the Obligee (who is protected), and the Surety (who guarantees performance)
- Unlike insurance, the surety expects no loss; if it pays a claim it has a right of reimbursement (subrogation/indemnity) against the principal, who signs a general indemnity agreement
- Contract/construction bonds include bid, performance, payment, and maintenance bonds; under the Miller Act, federal construction contracts above the FAR threshold (currently $150,000) require performance and payment bonds
- License and permit bonds are required by government to obtain a license and guarantee compliance with applicable laws; court/judicial bonds include appeal, attachment, and fiduciary bonds
- Surety underwriting evaluates the principal's character, capacity, and capital (the 'three Cs') much like a lender, because the surety extends credit, not loss protection
What a Surety Bond Is
A surety bond is a three-party guarantee that one party will perform an obligation to another. The surety does not assume an expected loss the way an insurer does; instead it lends its financial strength and credit, fully expecting the principal to perform. If the surety must pay, it holds a right of reimbursement against the principal under a signed general indemnity agreement.
Quick Answer: A surety bond guarantees performance or payment. Three parties are involved, and a paid claim is ultimately the principal's debt, not the surety's loss.
The Three Parties
| Party | Role | Construction Example |
|---|---|---|
| Principal | Owes the obligation; buys the bond | The contractor |
| Obligee | Protected by the bond; requires it | The project owner |
| Surety | Guarantees the principal's performance | The bonding company |
Surety vs. Insurance — The Defining Contrast
| Feature | Surety Bond | Insurance |
|---|---|---|
| Parties | Three | Two (insured, insurer) |
| Expected loss | None — none priced in | Losses expected and priced |
| Premium logic | Principal's creditworthiness (like a loan fee) | Actuarial loss experience |
| Recovery | Surety recovers from the principal | Insurer generally cannot recover from its insured |
| Purpose | Guarantee performance/payment | Transfer risk of loss |
Exam Key: The surety expects to pay zero losses. Underwriting resembles lending — the surety evaluates the principal's character, capacity, and capital (the "three Cs"). A paid bond claim is recovered from the principal, which is the opposite of insurance subrogation against a third party.
Types of Surety Bonds
Contract (Construction) Bonds
| Bond | Guarantees |
|---|---|
| Bid bond | The contractor will sign the contract (and furnish required bonds) if awarded the job |
| Performance bond | The project will be completed per the contract terms |
| Payment bond | Subcontractors and suppliers will be paid |
| Maintenance bond | Work will be free of defects for a stated period after completion |
Miller Act (federal projects): The statute names a $100,000 figure, but the operative threshold under the Federal Acquisition Regulation (FAR 28.102) is $150,000 — federal construction contracts above that amount require both a performance bond and a payment bond, each generally for 100% of the contract price. For contracts between roughly $35,000 and $150,000, the FAR allows alternative payment protections instead of a full payment bond. Many states have Little Miller Acts mirroring this for public works.
License and Permit Bonds
Required by a government body before issuing a license or permit; they guarantee the principal will comply with the governing law and protect the public from misconduct. Examples: contractor license bonds, motor-vehicle-dealer bonds, mortgage-broker bonds.
Court / Judicial Bonds
| Bond | Purpose |
|---|---|
| Appeal bond | Stays enforcement of a judgment during appeal |
| Attachment bond | Protects a defendant if plaintiff's pre-trial seizure was wrongful |
| Fiduciary bond | Guarantees an executor/administrator/guardian performs duties faithfully |
| Bail bond | Guarantees a defendant's court appearance |
Fidelity Bonds
Guarantee employee honesty and overlap with crime insurance's employee-theft coverage. They protect the employer from loss caused by dishonest employees and may be required by clients or regulators.
Worked Example
A general contractor wins a $4 million federal courthouse renovation. Because the contract exceeds the $150,000 FAR threshold, the surety issues a performance bond (guaranteeing completion) and a payment bond (guaranteeing subs and suppliers are paid). The contractor abandons the job at 70% complete. The surety arranges completion, pays a $900,000 shortfall — and then enforces the general indemnity agreement to recover that $900,000 from the contractor and its indemnitors.
Common Exam Traps
- "The surety expects losses" — false; the surety expects none and recovers any it pays.
- Bid vs. performance bond — bid guarantees the contractor will sign; performance guarantees completion.
- Miller Act figure — modern operative threshold is $150,000 under the FAR.
- Two vs. three parties — surety = three; insurance = two.
Underwriting the "Three Cs" and the Indemnity Agreement
Because the surety expects no loss, it underwrites the principal's ability to perform and repay, evaluating the classic three Cs: character (track record, reputation, claims history), capacity (technical and managerial ability to complete the obligation), and capital (financial strength — working capital, net worth, banking relationships). For contract bonds, the surety also reviews the principal's work program (how much bonded work is in progress) and may set a single-job and aggregate bonding limit.
Every commercial principal signs a General Indemnity Agreement (GIA), often joined by owners personally and sometimes spouses, pledging to reimburse the surety for any loss, including legal fees. The GIA is what converts a paid bond claim from the surety's expense into the principal's debt, and is the legal engine behind the surety's right of reimbursement.
Bid Spread, Forfeiture, and Public-Works Context
A bid bond does more than promise a signature: if the low bidder refuses to enter the contract, the obligee can recover the bid spread — the cost difference between the defaulting low bid and the next acceptable bid — up to the bond penalty (commonly 5–20% of the bid). This protects the owner from a bidder who lowballs and walks. On public projects, Little Miller Acts at the state level mirror the federal requirement so that subcontractors and suppliers on state and municipal jobs — who cannot file a mechanic's lien against public property — instead have recourse against the payment bond.
Understanding that public-property subs rely on the payment bond rather than lien rights is a recurring exam theme.
After a bonded contractor defaults, the surety spends $250,000 to complete the project. What can the surety do about that payment?
Under the Miller Act as implemented by the Federal Acquisition Regulation, federal construction contracts must carry performance and payment bonds when the contract price exceeds:
