What is excess and surplus insurance?


What are excess and surplus lines of insurance?

In E&S insurance, the term “lines” refers to the various commercial risk types or categories covered. Some businesses run operations that require E&S insurance, meaning the risks are too high or unique for the standard insurer.

For example, fire coverage for an oil company may be hard to insure through admitted channels given the complexity and nature of the risk. The following are several E&S insurance examples to help business owners understand what specialized policies might suit their operation given their hazardous activities. Excess and surplus lines of insurance include:

Property lines – Provides coverage for high-value, specialty property exposures like oil rigs, wind farms, and fine art collections.

Casualty lines – Offers liability coverage for hard-to-insure activities and occupations like construction, energy/mining, and healthcare.

Professional liability lines – Includes errors & omissions coverage for professions like architects, real estate agents, computer consultants, etc.

Financial lines – Covers specialized risks like management liability, cyber liability, financial institution bonds, etc.

Specialty lines – A coverage for unique risks like kidnap & ransom, aviation, and marine cargo that span multiple categories.

What’s the difference between E&S insurance and standard insurance?

One of the key distinctions between E&S and standard insurance is underwriting flexibility. E&S insurers can underwrite non-standard risks and customize policies with greater freedom, unlike standard insurers, who are bound by strict regulatory guidelines and filed underwriting rules. This allows E&S to more effectively manage complex risks on an individual basis.

Additionally, E&S insurers are willing to take on higher risk exposures that fall outside the risk tolerance thresholds of standard carriers. E&S policies often have broader coverage terms and conditions unavailable in standard forms and filings.

Standard policies use consistent state-filed forms. E&S can modify coverage/terms to better fit each risk’s needs. Therefore, E&S business is conducted outside admitted markets and is less regulated by states than standard commercial insurance.

The ability to underwrite and provide specialized policies for complex risks is the excess and surplus insurance definition that sets it apart from mainstream insurance.
