Surety and Fidelity Bonds

Key Takeaways

  • Surety is a three-party agreement (principal, obligee, surety) where the surety guarantees the principal's performance to the obligee; insurance is a two-party risk-transfer contract, and that distinction is the single most tested point
  • Surety expects zero losses and seeks full reimbursement from the principal through an indemnity agreement, so a paid bond claim is a debt the principal still owes
  • The Miller Act requires bid, performance, and payment bonds on federal construction contracts over $150,000; many states mirror it with 'Little Miller Acts'
  • Fidelity bonds protect an employer against employee dishonesty (theft, embezzlement); the ISO Commercial Crime form and the Financial Institution Bond are the standard fidelity products
  • On the exam, distinguish penal sum (maximum surety liability) from premium, and remember surety underwriting is credit underwriting, not loss-frequency underwriting

The Three-Party Structure of Surety

A surety bond is fundamentally different from an insurance policy, and examiners test that difference relentlessly. Insurance is a two-party contract transferring risk from an insured to an insurer in exchange for premium. Surety is a three-party guarantee.

The three parties are:

  • Principal - the party who buys the bond and promises to perform (e.g., the contractor).
  • Obligee - the party protected by the bond, to whom performance is owed (e.g., the project owner or a government agency).
  • Surety - the company that guarantees the principal will perform; if the principal defaults, the surety steps in.

Quick Answer: Insurance = two parties, expected losses. Surety = three parties, expected ZERO losses, with full reimbursement from the principal.

Because the surety expects to be reimbursed, the premium is really a service fee for the surety's financial backing and credit evaluation - not a pooled premium meant to fund losses.

Indemnity, the Penal Sum, and How Surety Underwrites

Every surety bond rests on a general indemnity agreement (GIA) the principal signs. When the surety pays a claim, the GIA obligates the principal to reimburse the surety in full. A paid surety claim is therefore a debt the principal still owes - this is the opposite of an insurance loss, which the insured does not repay.

The penal sum is the maximum dollar amount the surety can be required to pay - the ceiling of surety liability. Do not confuse it with the premium.

Worked example - penal sum vs. premium

A contractor wins a $2,000,000 public job. The obligee requires a performance bond at 100% of the contract. The penal sum is $2,000,000. If the surety's rate is 1.5% of contract value, the premium is 0.015 x $2,000,000 = $30,000. The surety can pay up to $2,000,000 on default, but only collected $30,000 - which is why surety underwriting is credit underwriting: the surety analyzes the principal's capital, capacity, and character (the 'three Cs') rather than loss frequency.

Contract Bonds and the Miller Act

The most heavily tested surety category is contract (construction) bonds, which guarantee a construction obligation:

Bond TypeWhat It Guarantees
Bid bondThe bidder will enter the contract at the bid price and furnish required bonds if it wins
Performance bondThe contractor will complete the project per the contract
Payment bondSubcontractors and suppliers will be paid (also called a labor-and-material bond)
Maintenance bondWorkmanship for a stated period after completion (often 1-2 years)
Supply bondMaterials will be delivered as contracted

The federal Miller Act requires performance and payment bonds on federal construction contracts exceeding $150,000 (and payment-protection alternatives for contracts of $35,000 to $150,000). Because federal property cannot be liened, the payment bond is the subcontractor's primary remedy. Most states have a 'Little Miller Act' applying similar rules to state and local public works.

Surety Is a Three-Party Credit Guarantee, Not Insurance

Suretyship guarantees the performance or honesty of one party to another. The three parties are the principal (who must perform), the obligee (who is protected), and the surety (who guarantees the principal). Unlike insurance, the surety expects no losses and, after paying the obligee, has a right of indemnity/reimbursement against the principal — the principal, not the surety, bears the ultimate cost.

Major Bond Categories Recap

Bond typeGuarantees
Bid bondWinning bidder will enter the contract and post the performance bond
Performance bondThe contract will be completed per terms
Payment bondSubs and suppliers will be paid (Miller Act for federal jobs)
License & permit bondCompliance with a law/ordinance
Fiduciary/court bondFaithful performance by an executor, guardian, etc.
Public official bondHonest performance of a public office

Fidelity Bonds vs. Commercial Crime

Fidelity bonds protect an employer against loss from employee dishonesty (theft, embezzlement). They evolve into the Commercial Crime program, which adds forgery, computer fraud, funds-transfer fraud, money-and-securities, and theft by non-employees. The crime form distinguishes loss-sustained (covers losses discovered during the period that occurred while coverage was in force) from discovery (covers losses discovered during the period regardless of when they occurred) — a tested distinction.

The penal sum is the bond's maximum, set by the obligee's requirement, and the premium is a small percentage of it because the surety underwrites for no expected loss.

Fidelity Bonds and Commercial Crime

Fidelity bonds protect an employer (the obligee) against financial loss caused by dishonest acts of its own employees - theft, embezzlement, forgery. The employee is the principal; the bonding company is the surety. Unlike contract bonds, fidelity coverage behaves much like crime insurance and is usually written on the ISO Commercial Crime program.

Key fidelity and crime insuring agreements to recognize on the exam:

  • Employee Theft - loss of money, securities, or property caused by employee dishonesty.
  • Forgery or Alteration - covering checks, drafts, and similar instruments.
  • Computer Fraud / Funds Transfer Fraud - electronic theft and fraudulent transfer instructions.
  • Financial Institution Bond - the specialized fidelity/crime form for banks and lenders.

A crucial distinction: the Loss Sustained form covers losses discovered during the policy period for acts committed while coverage was in force, while the Discovery form covers losses discovered during the policy period regardless of when the act occurred. Examiners contrast these two trigger bases.
