the answer comes to mind as, no. There is not likely to be a simple answer to the question of who insures. If the business is entirely owned and operated and conducted within one area then one insurance company might insure it, or one insurance might insure some of it and might farm out insurance coverage to commercial insurers for catastrophic loss coverage, or not. Expand the question to a business which is conducted outside of a single region of insurance coverage and then you can add optional headache of corporate legal team looking for liability loopholes in wording of insurance policy coverage, wording of international exemptions and laws, wording of space treaties, and any past precedent of proving strict liability and shared liability. Oh, and from what I was told many decades ago, the name of an insured is treated by the insurance company just like a trade secret. You can ask, maybe they would brag, but it's not a simple answer and there are places where it is legal to be self-insured and there is the possibility that some shady business would consider bankruptcy cheaper than insurance and stupidly think the corporate veil would save corporate officers from severally and collectively being liable.
