### Business Distribution
Our business is produced principally through brokers and reinsurance intermediaries. The brokerage distribution channel provides us with access to an efficient, global distribution system without the significant time and expense which would be otherwise incurred in creating wholly-owned distribution networks. The brokers and reinsurance intermediaries typically act in the interest of insureds, ceding clients or insurers and are instrumental to our continued relationship with our clients.
