Our Business

Segments

At Berkley, our business is divided into two segments: Insurance and Reinsurance. 

Each segment is comprised of individual Berkley companies, or “operating units,” which serve distinct markets requiring specialized knowledge of a particular territory, product or type of business. Together, they make up Berkley.

Insurance

Our Insurance segment underwrites predominately commercial insurance business throughout the United States and internationally. Certain Berkley companies in this segment write excess and surplus lines in the U.S. to cover highly complex risks with unique exposures that fall outside of the typical underwriting guidelines of the standard market. Others provide admitted insurance products and services in the U.S. to meet the needs of either a distinct regional group, including a wide variety of “Main Street” businesses, or the specialty risks of a particular type of customer. Berkley companies in the Insurance Segment write business worldwide, including the United Kingdom, Continental Europe, South America, Scandinavia, Australia and Asia. In each of our operating territories, products and services are tailored to the local customer base. 

Reinsurance

The Reinsurance segment provides other insurance companies and self-insured businesses with assistance managing their net risk through reinsurance in one of two ways: through treaty reinsurance on a portfolio basis, in which a Berkley company agrees to reinsure either a portion of the primary insurer’s business or certain classes of business defined under an agreement known as a treaty; or through facultative reinsurance, in which a Berkley company agrees to covers certain risks on a case-by-case basis. 

The reinsurance Berkley companies operate globally, primarily in the United States, the United Kingdom, Continental Europe, Australia and the Asia-Pacific Region.
