Excess Liability insurance protects organizations against catastrophic losses by providing coverage above primary insurance limits. Unlike traditional liability products, Excess Liability programs frequently involve multiple layers, attachment points, underlying insurance schedules, reinsurance participation, and highly customized underwriting. SelectRate enables insurance carriers, Managing General Agents (MGAs), wholesalers, program administrators, and specialty casualty insurers to configure, rate, test, govern, and deploy Excess Liability insurance products from one centralized commercial insurance rating platform. Whether you're writing Lead Excess, Follow Form Excess, Supported Excess, or complex layered casualty programs, SelectRate provides enterprise-grade product flexibility.
