One Insurance Program vs Separate Policies per Company

If you own several companies, one combined insurance program often costs less and is simpler to run when the companies do similar work and you plan to hold them together. Separate policies usually win when the risks differ sharply, when you may sell one company on its own, or when one company's claims could drag down pricing for the rest. This guide is for holding company owners and search fund CEOs deciding how to structure insurance after their second or third acquisition, and it includes a decision table you can run for your own group.

What is the difference between one program and separate policies?

In a combined program, one set of policies covers the whole group. The holding company is usually the first named insured (the entity that pays the premium, receives notices and controls the policy), and each operating company is added as another named insured. There is one renewal date, one set of limits and, usually, one carrier per line.

With separate policies, each company buys its own general liability, auto, property and workers' compensation, with its own limits, its own renewal and its own claims record. The holding company may carry nothing, or only its own management liability.

A hybrid sits in between: some lines are bought once for the whole group and others stay company by company. The broader holding company picture, including how to list entities, is in insurance for holding companies and roll-ups. This article is only about the structure decision.

What do you gain from one combined program?

• Buying power. A larger account can draw more interest from carriers and underwriters, and more room to negotiate terms. A small account and one several times its size often get different levels of attention from underwriters.
• Fewer minimum premiums. Small companies often pay a carrier's minimum premium on each policy, whatever their size. Folding them into one program can remove several of those floors.
• One renewal. One application, one set of loss runs, one renewal meeting and one date to budget for. For a lean holding company team, this is real time saved.
• Consistent coverage. Every company gets the same forms, endorsements and limits, so you are not discovering at claim time that one subsidiary bought a thinner policy.
• One umbrella. A single commercial umbrella over the whole group is often more efficient than a small umbrella at each company.

These gains are largest when the companies do similar work, so one carrier's appetite fits all of them, and when you plan to keep them together for years.

What do you give up with one program?

• Shared limits. On a combined general liability policy, every named insured usually draws on the same aggregate limit, the most the policy pays in a policy year. A large claim at one company can shrink what is left for the others. See general aggregate vs per occurrence. Endorsements that apply the general aggregate per location or per project, and in some markets per named insured, can reduce this, as can an umbrella sized for the whole group. Ask whether your program can carry them. These endorsements usually apply only to the general aggregate, not the separate products and completed operations aggregate, so a group with large completed operations exposure should size that aggregate and the umbrella for the whole group.
• A shared loss history. Underwriters price the program on the group's combined claims. One company with poor results can raise the renewal for everyone, and if a carrier decides to leave, it usually non-renews the whole program at once, not just the problem company.
• Control sits with the first named insured. Under the standard Insurance Services Office (ISO) common policy conditions, the first named insured pays the premium, receives any return premium and can cancel the policy. Carrier forms can vary, so check your own policy. That works when the holding company owns every company outright. It is awkward when a subsidiary has co-investors or its own lender.
• Premium allocation. One invoice has to be split across companies. Agree a method (by payroll, revenue, vehicles or the carrier's own rating worksheet) so each company's earnings, investor reports and lender reports show a fair share, and so a buyer can see a company's standalone insurance cost at exit.
• Claims between your own companies. Some policies exclude or limit claims one named insured brings against another. If your companies do work for each other, check the wording.
• Carve-out work at exit. Selling one company means removing it from the program and rebuilding its own coverage and loss history. More on that below.

Which structure fits your group?

Go through each factor for your group. If most rows point one way, that is your default. A split result usually means a hybrid.

Weigh the exit and ownership rows most heavily. A clean structure for a company you might sell in three years is often worth more than a few points of premium today. To compare the options on a total cost basis rather than premium alone, see total cost of risk for small holding companies.

What stays the same whichever structure you pick?

• Workers' compensation experience. Businesses with more than 50 percent common ownership are generally combined into one experience mod. That is the rule in states that use NCCI rules and in several states with their own rating bureau, such as New York, Minnesota and Pennsylvania. Writing separate workers' comp policies generally does not keep a bad record away from your other companies. The rating organization decides how combination works. See experience modification rate. In North Dakota, Ohio, Washington and Wyoming, private insurers cannot write workers' comp (it comes from the state fund, or self-insurance in some of those states), so those states sit outside any private program anyway.
• Correct entity names. Each legal entity, including any new acquisition company, must be listed. See wrong named insured after an acquisition.
• Contract and lender requirements. Every customer contract, lease and loan still has to be met, whoever holds the policy.
• Claims-made lines. Directors and officers, employment practices and cyber policies keep their own retroactive dates and change in control terms either way.

What happens when you sell one company?

With separate policies, a stock sale is simple: the company's policies stay with the entity, subject to any change in control terms. In an asset sale, the policies generally stay with your selling entity, and the buyer needs its own coverage from closing. With a combined program, you carve the company out.

1. Remove the company as a named insured from the sale date, and make sure the buyer has its own coverage from that day.
2. Remember that past occurrence policy years still generally cover the sold company for injury or damage during those years, so later claims can land on your program, use its aggregates and show on your loss runs.
3. For claims-made lines, agree in the purchase agreement who buys a tail (extended reporting period) or keeps the retroactive date. See prior acts and tail coverage.
4. Produce a standalone loss history for the buyer. This is easy only if the carrier coded claims by company all along.

A hypothetical example. A holding company owns two heating and cooling service companies and a small sign maker, all on one program renewing January 1, with a $2 million products and completed operations aggregate. A sign the sign maker installed the year before falls in May and injures a pedestrian, but no claim is made at first. The group sells the sign maker in July. In October, the pedestrian's lawyer files suit. Because the injury happened in May, while the sign maker was still a named insured, the claim would likely go to the program, subject to the policy wording. It would use part of that shared products aggregate and show on the group's loss runs at the next renewal, even though the group no longer owns the company. An injury after the sale date would generally go to the buyer's own policy instead. Meanwhile, the buyer asked for the sign maker's own five-year loss history during diligence, and it took weeks to assemble because claims were never tracked by company. Neither problem is fatal, but both were foreseeable at the add-on stage.

A clean, company-level loss record is part of what you sell. See how a clean loss history raises your exit value.

What does a sensible hybrid look like?

Many groups split lines by where the risk really sits. This is a common pattern, not a rule; your carriers, contracts and lenders may push it in a different direction.

Whatever split you choose, write it down, review it with each add-on and use the add-on consolidation playbook when a new company joins the shared lines. A Morrow review can lay out both structures side by side for your group, with any new terms depending on carrier underwriting.

Frequently asked questions

Is one insurance program always cheaper than separate policies?

Not always. A combined program often lowers total premium through buying power and fewer minimum premiums, but a company with a poor loss record or a very different hazard can raise the price for the whole group. Ask for both structures quoted and compare total cost, including deductibles and admin time.

Can my companies have separate policies but share an umbrella?

Often, yes. Many groups buy one umbrella over the group and keep primary policies at each company. The umbrella usually has to list each company's primary policies in its schedule of underlying insurance, and the umbrella limit is shared, so size it for the group.

Will separate workers' comp policies keep one company's bad mod away from the others?

Usually not. In NCCI states and several states with their own rating bureau, such as New York and Pennsylvania, companies with more than 50 percent common ownership are generally combined into one experience mod regardless of how many policies you buy. The rating organization decides how the experience is combined.

Who controls a combined policy if a subsidiary has its own investors?

Under standard policy conditions, the first named insured pays the premium, receives refunds and can cancel the policy. If a subsidiary has co-investors or its own lender, that control may not fit, and separate policies or specific endorsements may be cleaner. Ask deal counsel how your operating agreements treat it.

When should I decide on the structure for a new add-on?

Before closing. The add-on needs coverage from closing day, and the choice affects whether you add it to your program now, run its policies to expiry or keep it separate. Changing structure later can mean short-term policies or cancellation costs.
