16.1 Surety and Fidelity Bonds

Key Takeaways

  • A surety bond is a three-party guarantee (principal, obligee, surety); the surety expects zero net loss and recovers from the principal under a General Indemnity Agreement.
  • Bid, performance, payment, and maintenance are contract bonds; the Miller Act requires both performance and payment bonds on federal construction contracts over $150,000.
  • Fidelity bonds protect an employer from its own employees' dishonesty and behave like insurance (no recovery expected).
  • A commercial blanket bond pays one limit per occurrence; a blanket position bond pays the limit separately for each dishonest employee.
  • Sureties underwrite the three C's: Capital, Capacity, and Character.

Surety Bonds: A Three-Party Guarantee

A surety bond is not insurance in the ordinary sense. It is a three-party financial guarantee that one party will fulfill an obligation to another. The three parties are the principal (the party who must perform the obligation), the obligee (the party protected by the bond, who receives payment if the principal defaults), and the surety (the company that guarantees performance and pays the obligee on default).

The defining feature, tested repeatedly, is that the surety expects zero net loss. Unlike an insurer, which prices premiums to fund expected claims, a surety underwrites the bond as a credit risk and expects to recover any amount it pays the obligee from the principal. That recovery right is secured by a General Indemnity Agreement (GIA) the principal signs before the bond issues, pledging assets and often personal guarantees of the owners.

The Three C's and the Penal Sum

Because the surety expects full reimbursement, it underwrites the principal almost like a lender. The standard memory device is the three C's: Capital (does the principal have the financial strength to perform and to indemnify?), Capacity (does it have the equipment, staff, and experience to complete the work?), and Character (does its track record show it pays subcontractors and finishes jobs?).

Every surety bond has a penal sum — the maximum dollar amount the surety will pay the obligee. The surety's liability never exceeds the penal sum even if the cost to cure the default is higher. The premium is a service charge for the guarantee and the credit underwriting, not a pooled loss fund.

Contract Surety Bond Types

Contract Bonds and the Miller Act

The four contract bonds above move in sequence on a construction job: a bid bond at award, then performance and payment bonds during the work, then a maintenance bond after acceptance. Exam items frequently ask which bond protects subcontractors — the answer is the payment bond, never the performance bond.

The federal Miller Act is a high-yield fact. On federal construction contracts exceeding $150,000, the prime contractor must furnish both a performance bond and a payment bond. The performance bond protects the United States as obligee; the payment bond protects subcontractors and suppliers who cannot file mechanic's liens against federal property. State "Little Miller Acts" impose parallel requirements on state and municipal public works.

Fidelity Bonds: Protecting the Employer

Fidelity bonds reverse the surety relationship. A fidelity bond protects an employer against financial loss caused by the dishonest acts — theft, embezzlement, forgery — of its own employees. Here the protected party and the party buying the bond are the same entity, so the bond behaves like insurance: the writing company expects to pay losses and does not seek recovery from the dishonest employee (beyond ordinary subrogation).

Two blanket structures are commonly tested. A commercial blanket bond pays a single limit per loss occurrence, regardless of how many employees were involved. A blanket position bond applies the full limit separately to each dishonest employee, so a scheme involving three colluding employees can recover up to three times the per-employee limit. Candidates should expect a calculation that turns on this distinction.

Surety vs. Insurance and Common License Bonds

The cleanest way to lock in the difference for the exam is a side-by-side contrast. Insurance is a two-party contract in which the insurer pools premiums and expects to pay losses; there is no expectation of recovery from the insured. Surety is a three-party contract in which the surety guarantees a credit-like obligation and expects to recover every dollar it pays from the principal under the General Indemnity Agreement. A loss to the surety is treated as a failed credit decision, not an insured event.

Beyond contract bonds, candidates should recognize the broad license and permit bond category. These guarantee that a licensed party — a contractor, mortgage broker, auto dealer, or notary — will comply with the laws governing the license, and they pay the public obligee if the principal violates those laws. Court bonds (such as appeal bonds, fiduciary bonds, and probate bonds) guarantee performance of duties imposed by a court. Both behave like surety: the penal sum caps the surety's exposure, and the principal indemnifies any payment.

A final distinction examiners exploit: a surety bond's premium is not a function of expected losses but of the principal's creditworthiness and the bond's penal sum, while a fidelity bond is rated like insurance on expected employee-dishonesty losses. When a question contrasts how each is priced, tie surety pricing to underwriting the three C's and fidelity pricing to loss experience. Remember also that the obligee never pays for a surety bond and never indemnifies the surety; that burden falls entirely on the principal.
