For more than ten years, subcontractor default insurance has been promoted as a substitute for subcontractor performance bonds. [i]

However, there are significant differences between bonds and default insurance.

Subcontractor default insurance does not perform or offer the same extent of protection as subcontractor bonds. Two of the key differences between surety bonds and subcontractor default insurance are prequalification and payment protection. As these differences become clear, surety bonds stand out as the most effective means to prevent subcontractor default and assure payment to the subcontractor's subs and suppliers.


A surety seeks to avoid a default by providing bonds only to those contractors it believes are qualified to perform the work. Long ago, the book of Proverbs cautioned against being a "surety for a stranger."[i] Effective and successful surety bond underwriting requires the surety to know the subcontractor's operation fully. A surety examines the subcontractor's character, capacity and capital to be as certain as it can be that the subcontractor can perform the work to be bonded. The surety reviews the subcontractor's financial statements, evaluates the subcontractor's experience and assesses the subcontractor's organization and equipment. The surety typically will obtain the following information from the subcontractor:

  • Quarterly financial statements
  • Updated backlog data
  • Bank letter regarding any line of credit
  • Organizational information
  • Business plans/bonding needs
  • Information regarding the specific project to be bonded including a copy of the construction contract

Moreover, underwriting is a continuing process for as long as the surety is providing bonds to the subcontractor. In light of this extensive prequalification process, it is not surprising that subcontractors often have long-standing relationships with their sureties. Subcontractors understandably want to limit the number of parties that have access to their proprietary information. In addition, a surety that has a long relationship with a subcontractor likely will be more willing to provide bonding credit on a project that might be a "stretch" for the subcontractor than a surety that is new to the subcontractor.

Subcontractor default insurance attempts to implement a prequalification scheme as well. The policy marketed by Zurich North America, Subguard, permits the insurer to cancel the policy "[u]pon repeated violations in the application of your Qualification procedures."[ii] "Qualification procedures" is defined as "written criteria that you have represented that you will adhere to in order to assure that the Subcontractor/Supplier will be able to carry out the terms of the Covered subcontract or purchase order agreement."[iii] Thus, the policy relies on the contractor to implement its own prequalification procedures. However, this prequalification is a lesser substitute to the prequalification performed by a surety bond for three reasons.

  1. The prequalification scheme contemplated under subcontractor default insurance is not available to all general contractors. Generally, only large contractors have the resources and personnel necessary to review subcontractor qualifications. In fact, the product is available only to large contractors that meet a minimum threshold for subcontractor/supplier expenditures. The prequalification services offered by a surety bond are available to any general contractor that requires a performance bond from its subcontractors.
  2. Although a general contractor may have the resources and personnel to review a subcontractor, its prequalification process cannot match the detailed and continuing review provided by a surety. A general contractor that has a prequalification process typically requires the subcontractor to complete a questionnaire regarding its operation and annually submit a financial statement. Although the questionnaire can be detailed, the prequalification pales in comparison to the surety's review. For example, contractor questionnaires typically require an annual financial statement. A surety will require an annual financial statement, quarterly financial statements and quarterly work on hand schedules. Based on the extent of information provided, a surety likely will be able to detect problems on the subcontractor's other projects before the general contractor detects a problem. Experience shows that the subcontractor's weaknesses that caused the problems on the other projects eventually find their way to the project being bonded. A limited review of a financial statement, which is only a snapshot of the subcontractor's financial position at a point in time, likely will not detect problems that do not exist at the time of the financial statement. Interestingly, perhaps as an acknowledgement of the quality of a surety's prequalification, many questionnaires require the subcontractor's surety to provide a letter that indicates that the subcontractor is bondable for a certain amount.
  3. Subcontractors are uncomfortable providing proprietary information required in the prequalification process to general contractors.[iv] Given the long-term relationship between subcontractor and surety, a subcontractor likely is less hesitant to share its company information with its surety.

The president of the American Subcontractors Association Midwest Council commented on the thoroughness of surety prequalification relative to the review by a general contractor by stating, "In the case of our surety, I am confident that it looks at more than just financial statements, as I work very closely with our insurance company and surety to ensure that they understand the type of work we do and the risks and benefits of this type of work."[v]

Prequalification is the chief protection against loss under surety bonds. Because the prequalification scheme under default insurance falls short in certain respects, the subcontractor default policy imposes other terms and conditions to mitigate the insurer's loss---terms and conditions that are not in a surety bond.[vi]

Coverage is subject to an aggregate limit for all subcontractor losses under the policy. Thus, depending on the particular aggregate limit on the policy, multiple subcontractor losses on a project could lead to less than 100 percent coverage. A surety bond secures 100 percent of the subcontract amount. In addition a subcontractor default policy may be subject to a deductible. Thus indemnity is afforded under the policy after application of the deductible amount, which can be in the $500,000 range.[vii] A surety bond does not have a deductible.

A subcontractor default policy typically is subject to a number of exclusions (Subguard Policy, Exclusions, § III.), so that coverage does not apply to loss:
