What Is Surplus Lines Insurance?
Surplus lines insurance — also called non-admitted or Excess and Surplus (E&S) insurance — refers to coverage placed with an insurance carrier that is not licensed in the insured's home state. Surplus lines carriers are used when a risk cannot be placed with admitted (state-licensed) markets, either because the risk is too large, has too many prior claims, falls outside the standard market's underwriting appetite, or requires policy terms that admitted carriers are not permitted to offer. Subject to state-specific surplus lines regulations, placement requires documentation that admitted markets were first solicited.
Why EPLI Risks Go to Surplus Lines
A significant portion of EPLI placements — particularly in California — end up in surplus lines markets. Admitted carriers have defined underwriting appetites that reflect both their risk tolerance and state regulatory requirements around rates and forms. When a risk falls outside those parameters, the E&S market provides an alternative avenue to coverage that might otherwise be unavailable.
Common reasons an EPLI risk goes to surplus lines include:
- Prior EEOC or CRD charges, particularly multiple charges or charges involving senior leadership
- Large employee headcount exceeding admitted carrier appetite thresholds
- High-risk industries: staffing agencies, healthcare, hospitality, restaurants, adult entertainment, cannabis
- Prior EPLI claims, especially multiple claims or claims settled for significant amounts
- Accounts requiring manuscript endorsements, higher limits, or coverage structures not available in admitted forms
- California-based accounts in classes where admitted carriers have exited or restricted appetite
E&S markets generally have more underwriting flexibility than admitted carriers because their rates and forms are not subject to state approval. This means they can write risks, offer terms, and price accounts in ways that admitted carriers cannot — making them an essential part of the EPLI market, not a fallback option of last resort.
How Surplus Lines Placement Works
In most states, including California, a licensed surplus lines broker must first conduct a "diligent search" — soliciting admitted carriers and documenting their declinations before proceeding to the non-admitted market. The number of required declinations varies by state (typically three in California). This documentation protects both the broker and the insured by creating a record that the admitted market was genuinely unavailable for the risk.
Once the diligent search is documented, the policy is placed with a surplus lines carrier — often through a wholesale broker or managing general agent (MGA) that specializes in the relevant line of coverage. The submission goes to a surplus lines underwriter who evaluates the risk and issues a quote on the carrier's non-admitted paper.
In addition to the base premium, surplus lines placements include two additional charges: a surplus lines tax (typically 3% of premium in California) payable to the state, and a surplus lines stamping office fee (typically 0.1% to 0.25% of premium) assessed by the California Surplus Lines Association (CSLA) or equivalent body. These charges are generally disclosed on the policy declarations or in a separate fee disclosure and are in addition to — not included in — the base premium quoted.
Key Differences from Admitted Coverage
Standard Market
- Licensed by state Department of Insurance
- Rates and forms filed with and approved by state
- State guaranty fund protection if carrier becomes insolvent
- More standardized policy forms
- No diligent search required
- No surplus lines tax or stamping fee
Non-Admitted Market
- Not licensed in insured's home state
- Rates and forms not subject to state approval — greater flexibility
- No state guaranty fund — policyholders are unsecured creditors if insolvent
- Often broader or more tailored policy forms
- Diligent search of admitted markets typically required
- Surplus lines tax (~3% CA) and stamping fee added to premium
- Some of the most sophisticated EPLI underwriters (Lloyd's, specialty E&S)
Surplus Lines Is Not Inferior — It Is Often Essential
Many of the most sophisticated and experienced EPLI carriers — including Lloyd's of London syndicates and leading specialty E&S carriers — operate on a non-admitted basis. These carriers have been writing employment practices liability coverage since the early 1990s and have developed deep institutional knowledge of EPLI claim trends, California-specific risks, and complex employment litigation dynamics that many admitted carriers simply do not match.
Because surplus lines markets are not bound by state-approved form restrictions, they can offer manuscript endorsements tailored to the insured's specific risk, higher limits than some admitted carriers are approved to offer, and coverage structures — such as duty-to-defend versus reimbursement forms — that an insured prefers. For complex EPLI accounts in California, the E&S market is frequently the right market.
The appropriate question when evaluating a surplus lines EPLI carrier is not "is this an admitted carrier?" but rather "what is this carrier's AM Best financial strength rating, what is their EPLI claims handling reputation, and does this policy form provide the coverage my business needs?" Financial strength — typically AM Best A- or better — is the right proxy for carrier reliability, not admitted vs. non-admitted status.
California Staffing Agency — Admitted Declined, E&S Steps In
A California staffing agency with 400 placed workers and two prior EEOC charges seeks $1M/$2M EPLI limits. Three admitted carriers decline to quote, citing the combination of prior charges and staffing industry exposure. The broker documents the declinations as part of the required diligent search, then submits the risk to a surplus lines market with specialty EPLI underwriting capability.
The surplus lines carrier quotes the risk with a specific exclusion for one of the prior charges and a $25,000 retention. The employer receives $1M/$2M limits on a non-admitted basis — coverage they could not obtain in the admitted market. The premium includes a 3% California surplus lines tax and a nominal stamping office fee disclosed on the declarations page.
Key takeaway: The surplus lines market is often the only available market for EPLI risks with prior charges, unusual industries, or California exposure — and it is frequently served by the most experienced EPLI underwriters in the country. Admitted market declinations are not the end of the road.
Common Mistakes Employers Make
-
Assuming surplus lines EPLI is lower quality
Some of the best EPLI carriers in the country operate on a non-admitted basis. Lloyd's of London syndicates and major specialty E&S carriers have more EPLI experience and broader policy forms than many admitted competitors. Quality is determined by the carrier's expertise, financial strength, and policy terms — not by admitted status.
-
Not understanding the guaranty fund difference
Surplus lines carriers do not participate in state guaranty funds. For large accounts with significant EPLI exposure, this is a meaningful consideration. Evaluate the carrier's AM Best financial strength rating regardless of admitted vs. non-admitted status — and be aware that the guaranty fund distinction matters more for large accounts than for small ones.
-
Not knowing about the surplus lines tax and stamping fee
Surplus lines placements include a state tax (typically 3% in California) and a stamping office fee on top of the base premium. These charges add to the total cost and should be factored into budget comparisons between admitted and non-admitted options. They are generally disclosed on the policy declarations.
-
Automatically choosing admitted over well-rated surplus lines options
An admitted carrier with limited EPLI appetite and a narrow policy form may be a worse choice than a well-rated surplus lines carrier with deep EPLI expertise and a broader form. Work with an EPLI broker who has access to both markets and can make an honest comparison based on coverage, not just carrier status.

Frequently Asked Questions
What is surplus lines insurance?
Surplus lines insurance — also known as non-admitted or E&S (Excess and Surplus) insurance — is coverage placed with a carrier that is not licensed in the insured's state. It is used when the risk cannot be placed in the standard (admitted) market due to the risk's size, claims history, industry, or other characteristics. Surplus lines carriers have more underwriting flexibility but do not participate in state guaranty funds.
When does EPLI go to surplus lines?
EPLI typically goes to surplus lines when admitted carriers decline to quote or offer unacceptable terms. Common triggers include prior EEOC or CRD charges, prior EPLI claims, large employee counts, high-risk industries (staffing, hospitality, healthcare), or California-based accounts in classes where admitted carriers have restricted their appetite. A qualified EPLI broker can assess whether admitted or surplus lines markets are most appropriate for a given account.
Is surplus lines EPLI less reliable than admitted coverage?
Not necessarily. Many of the most capable EPLI carriers — including Lloyd's of London syndicates and leading specialty E&S carriers — are non-admitted. The key distinction is the absence of state guaranty fund protection: if a surplus lines carrier becomes insolvent, the policyholder does not have the same state-backed safety net as with an admitted carrier. Policyholders should evaluate the financial strength ratings (e.g., AM Best A- or better) of any EPLI carrier, whether admitted or non-admitted.
What is a stamping office fee?
A stamping office fee is a small charge — typically 0.1% to 0.25% of the policy premium — assessed by a state's surplus lines stamping office to fund regulatory oversight of non-admitted placements. It is separate from the surplus lines tax (which is typically around 3% in California). Both fees are generally disclosed on the policy declarations or in a separate fee disclosure and are in addition to the base premium.
