# Group Captive or Single-Parent Captive: How Construction Firms Typically Decide URL: https://mycontractorsinsurancequote.com/resources/group-vs-single-parent-captive Updated: 2026-10-29 · Reviewed by the Principal, Gleason Insurance Brokers, LLC Publisher: My Contractors Insurance Quote, a website of Gleason Insurance Brokers, LLC A single-parent captive insures one company and its affiliates and gives that owner the most control, while a group captive pools several companies that share part of each other's losses under common rules. Which one fits usually depends on premium size, loss predictability, appetite for shared risk and the capital the owners can commit. Each program sets its own entry standards and terms, and either structure is subject to regulatory approval and underwriting. ## Key Decision Points - A single-parent captive offers the most control over claims, retentions and investments but carries the full capital and operating cost. - A group captive spreads fixed costs and losses across members, so a firm too small for its own company may still participate. - Group members commonly share losses through a risk-sharing layer and can be assessed after a bad year for the group. - Cells in a sponsored or protected cell captive offer a middle path with separated assets and lower entry capital. - Exit terms and run-off of open claims matter as much as the entry price. ## The Single-Parent Captive A pure or single-parent captive belongs to one owner and insures the risks of that owner, its affiliates and, in some domiciles, controlled unaffiliated businesses such as key subcontractors under contract. The owner chooses the retention, the claims administrator, the reinsurers and the investment policy, and it keeps the underwriting result when losses come in below what was funded. That control comes with the full cost. The owner capitalizes the company, pays the captive manager, auditor and actuary and carries every loss in the retained layer. Statutory minimums for a pure captive run from about $200,000 in Nevada to $250,000 in Arizona and Texas, and regulators and fronting carriers commonly require more for construction risks. The full range of options is set out in our overview of [captive structures for construction firms](https://mycontractorsinsurancequote.com/construction-captive-insurance-programs). ## The Group or Association Captive A group captive brings together several companies, often in the same industry, that agree to underwriting standards, safety expectations and a shared governance model. Each member typically funds its own losses up to a point and shares a pooled layer above it with the other members, with reinsurance above the pool. For a contractor, the appeal is access: a firm with steady losses but not enough premium for a company of its own can still retain part of its risk and see its own results. The trade-off is shared exposure. If other members have a bad year, the pooled layer can cost more, and many programs can assess members or hold back returns. Whether a group or a company of your own fits is what a [captive feasibility review](https://mycontractorsinsurancequote.com/resources/construction-captive-feasibility). ### Illustrative scenario: A Texas Developer Chooses a Cell Over a Company of Its Own A Dallas-Fort Worth developer with a portfolio of multifamily projects considers forming a pure captive for its general liability. The actuarial study shows its premium can support a retained layer but not the fixed cost of running a company, and the developer is not comfortable sharing losses with unrelated members in a group. A cell in a sponsored captive domiciled outside Texas gives it a segregated retained layer at a lower capital entry point, while its for-sale condo phase stays on a project-specific policy and its workers' compensation stays with an authorized insurer. The developer's tax advisor reviews the cell before it signs. The details are hypothetical, and a real choice would depend on the programs, domicile rules and carriers involved. ## Cells, Rental Captives and Risk Retention Groups Some domiciles allow a sponsor to run a captive with separate cells. In Nevada, sponsored captives fund participants through protected cells, and Arizona licenses protected cell captives whose cells keep assets and liabilities apart. A cell lets a company retain its own risk without forming a company, at a lower capital entry point, though the sponsor's rules and fees apply. Risk retention groups are member-owned liability insurers formed under the federal Liability Risk Retention Act. They can serve members in many states once chartered in one, but they write liability only. - Cell: segregated assets inside a sponsor's captive, sponsor sets the rules - Rental captive: a company uses another owner's licensed captive for a fee - Risk retention group: member-owned, liability only, chartered in one state ## What Usually Decides the Choice Premium size and loss predictability come first, because they determine whether a company of one's own can be priced and capitalized. Next come control and appetite for shared risk: owners who want to set every term tend toward a single-parent captive, while owners comfortable with common rules may prefer a group. Contract requirements and the lines to be written can override both, since state law limits which lines a captive may write directly and many owners require admitted paper through a fronting carrier. - Premium spend and years of credible loss data - Willingness to share losses and governance - Capital and collateral the owners can commit - Lines needed and each domicile's limits - Exit terms and run-off of open claims How a developer's portfolio might use either structure is part of our guide to [developer and subdivider insurance programs](https://mycontractorsinsurancequote.com/who-we-serve/developers-subdividers). ## Exit Terms and Run-Off Leaving a captive is rarely a clean break. A single-parent owner may run off open claims inside its company for years or transfer them to another carrier. A group member typically remains responsible for its share of losses from the years it participated, and the program may hold collateral or returns until those claims close. Reading the exit provisions before joining is one of the most useful steps in the whole decision, because they decide what a departure costs in a bad year.

Cells and rental captives sit between them. The choice usually turns on premium size, loss predictability and appetite for shared risk. **Common Mistake:** Comparing entry price alone. The shared layer, assessment rights and exit terms decide what a group costs in a bad year, and the fixed operating cost decides what a single-parent captive costs in a quiet one. **Broker Perspective:** We put the group program's rules and the single-parent model side by side on the same loss data, then look at what each would have cost in the firm's worst recent year. **Coverage Impact:** Neither structure changes the coverage forms on its own; what is insured depends on the fronting policies, reinsurance and endorsements issued for the program. ## Questions Buyers Ask ### Can a group captive member be charged more after a bad year? Often, yes. Many group programs can assess members or reduce returns when the pooled layer performs poorly. The program documents describe how and when. ### Is a cell captive cheaper to start than a pure captive? Usually the entry capital is lower because the sponsor's company is already licensed, but the sponsor charges fees and sets rules for each cell. The full cost depends on the sponsor and the program. ### Can our key subcontractors be insured by our captive? In some domiciles a pure captive may insure controlled unaffiliated businesses, such as businesses under contract with an affiliate. Whether that fits depends on the domicile's statute and the program's design. ### Does a risk retention group cover workers' compensation? No. Under the federal Liability Risk Retention Act, a risk retention group writes liability insurance only. ## Official Sources 1.
