Commercial umbrella insurance
Though the terms are sometimes used interchangeably, commercial umbrella insurance and excess liability insurance do not refer to the same policy.
Commercial umbrella insurance can increase the limit of three policies: general liability insurance, employer's liability insurance, and commercial auto liability insurance. It protects against the most expensive liability lawsuits.
Commercial umbrella insurance costs about $40 per month for each $1 million of additional coverage. Your level of risk and how much coverage you buy determine the cost of this policy.
