Four states do not allow the purchase of workers compensation through a private insurance company. Instead of using private carriers, all four of these states use a State-Run Fund. As such, in North Dakota, Ohio, Washington and Wyoming, the employer cannot buy their worker's compensation coverage from anyone else and has no renewal to shop for the best possible rates. Due to this, when an employer has employees working in different states, they will have to obtain a separate policy with the state fund for each state. Consequently, the employee's wage(s) will have to be carved out into each respective policy. In addition to carving out the employee's wage(s), employers will need to add Stop-Gap Employers Liability (and/or other language) to their Commercial General Liability (CGL) Policy. The additional layer of protection is necessary because although monopolies may exist in some states, in neither Item 3.A. nor Item 3.C. of the Standard Form Policy can the name of a monopoly appear.
Before making sense of anything else, you should be able to determine what the front page of a worker's compensation policy really looks like. The front page contains numbered slots, and almost all of the work is done by only two of those slots.
- Item 3.A.States included under coverage
- List of states whose worker's compensation laws this policy provides benefits under.What it decides: An employee injured in a state not listed will get no benefits from this policy, regardless of how high your limits are.Example entry: California
- Item 3.B.Employers liability limits
- The dollar limits available when an injured employee sues you instead of, or on top of, claiming benefits.What it decides: These limits only reach the states listed in Item 3.A.Example entry: $1,000,000 each accident
- Item 3.C.Other states insurance
- A backstop list covering states where you unexpectedly start work during the policy year.What it decides: It buys you time to tell your insurer about a new state, and it cannot be used for North Dakota, Ohio, Washington or Wyoming.
- Item 3.D.Endorsements
- The list of attachments that change the standard policy wording.What it decides: This is where stop gap coverage appears if you have it.

Monopolistic State Fund
Monopolistic state funds are state-created, state-owned and state-operated workers compensation insurance facilities that issue all workers compensation coverage within a specific state. This excludes private carriers, who can write no workers compensation coverage within the same state.
What are the four monopolistic states and their funds?
The four government run monopolistic states (North Dakota, Ohio, Washington, and Wyoming) each have a single fund that handles all workers compensation policy writings. Thusly, the individual funds have developed their own systems for categorizing and pricing risk and therefore do not adhere to any NCCI classification/rating standards. This creates a situation where an employer with operations in multiple states can expect that their work classifications and experience-rated premiums cannot be transferred from state-to-state. In addition to this, Washington L&I calculates its premium on an hourly basis as opposed to per $100 of payroll, which is the only state to use an hourly system[1]. Therefore, vacation/sick time are excluded from the exposure base.
Only Ohio and Washington allow qualified employers to be self-insured. The remaining two monopolistic states, North Dakota[2] and Wyoming[3], offer no other means for employers to avoid paying premiums into a required pool. They are thus forced to purchase insurance products from their state's single monopoly insurer:
| State | Fund | Self-Insurance Option |
|---|---|---|
| North Dakota | Workforce Safety and Insurance (WSI) | No |
| Ohio | Ohio Bureau of Workers' Compensation (BWC) | Yes, for qualified employers |
| Washington | Department of Labor and Industries (L&I) | Yes, for qualified employers |
| Wyoming | Department of Workforce Services | No |
How do Item 3.A. and Item 3.C. handle monopolistic states?
The Coverage Territory for the workers compensation policy Standard is controlled on the "Information" page and the monopolistic states are removed from both of the items offering this coverage. Item 3.A. will cause Part One statutory coverage to become active for those states where operation will take place under Part One, however, as no private carrier can write a monopolistic state, it cannot appear there. Item 3.C. (Other States), provides coverage for all other states in which work begins subsequent to the effective date of Item 3.C. Nevertheless, Item 3.C. specifically excludes the four mentioned states.
The only exception to reciprocity is that stated by the Fund itself. While Washington L&I has reciprocal agreements with Idaho, Oregon and some other Western States, both of their reciprocal agreements with Montana and Nevada have specific exclusions from these reciprocity agreements for construction[4]. Do NOT assume a reciprocal agreement exists until it has been confirmed in writing by the Fund.
Remote employees sharpen the same edge. An employee who works from home in Ohio is Ohio payroll, which neither item can reach. The employer must enroll with the Ohio BWC[5], the private carrier's auditor will strip that payroll from the standard policy, and the fund will not backdate it.
What is stop gap coverage and why do you need it?
A stop-gap endorsement (employers liability protection) is attached to a client's existing commercial general liability policy in order to provide coverage for monopolistic state exposures. Funds are responsible for paying statutory benefits but also have no responsibility for employers liability. The Part Two, which every standard workers compensation policy provides when the injured worker elects to sue as opposed to taking the benefit available through the workers compensation system, is what the stop gap adds back to the CGL for third-party action over claims, consortium or dual-capacity claims against the employer and all other lawsuits claiming that the employer was negligent. The CGL would decline these types of cases anyway due to the employee injury exclusion without such a stopgap endorsement.
Most umbrellas require an underlying employers liability policy ($1,000,000) therefore, you should be quoting stopgap at that same level and NOT at the minimum levels of Part Two:
| Standard Stop Gap Minimum Level (Part Two) | Recommended Stop Gap Limit | |
|---|---|---|
| Bodily injury by accident, each accident | $100,000 | $1,000,000 |
| Bodily injury by disease, policy limit | $500,000 | $1,000,000 |
| Bodily injury by disease, each employee | $100,000 | $1,000,000 |
How do certificates of insurance work with state funds?
The issue is that there is nothing to indicate an employer liability gap from viewing the certificate of insurance, because the Fund has its own and your ACORD 25 cannot stand in for coverage that your agency does not control. Show the Stop Gap under the General Liability section on your certificate of insurance. Do Not Certify a policy that was issued by a Fund to place coverage into the Workers Comp box as if your agency purchased that coverage, another very common fact pattern relating to errors & omissions.
Frequently asked questions
What is a monopolistic state?
Four Monopolistic States currently exist in the United States, where state laws prohibit private insurance carriers from offering or selling Workers Compensation Insurance as a competitor to the state fund. Therefore, if you operate in one of those four monopolistic states, you can only obtain Workers Compensation Insurance via the state fund. The four monopoly states for worker compensation insurance in the United States are Ohio, North Dakota, Washington and Wyoming.
Do monopolistic state funds include employers liability coverage?
No. The funds pay statutory workers compensation benefits only. Employers liability protection for suits outside the exclusive remedy, such as third party action over claims or alleged employer negligence, must come from stop gap coverage endorsed onto the employer's commercial general liability policy.
What happens if a client starts work in a monopolistic state without enrolling in the fund?
This signifies that they are at a risk of which there is no insurance coverage. All monopolistic states are excluded under the standard policy form on both items. Monopolistic state funds do not go back in time and provide coverage retroactively. If clients do not enroll in one of these programs before beginning their job, they will face additional risks including but not limited to state fines and penalties and will also be obligated to pay the uninsured claims out-of-pocket as well as possible lawsuits.

The Bottom Line
There are four monopolistic states (North Dakota, Ohio, Washington & Wyoming) where an employer in those states may only obtain worker's comp coverage through a state fund (never private). The State Fund will cover all statutorily required employee benefits, however, they do NOT provide Employers Liability. Due to this reason, we recommend adding Stop-Gap Coverage to your CGL Policy. We recommend you enroll with the state fund before beginning work because the State Fund will not backdate coverage. Also, keep the state out of Item 3.A. and 3.C., and verify the Stop-Gap Endorsement at every renewal.
