There are hundreds of national and regional firms, including insurance companies, that compete to provide workers' compensation claims administration services for private as well as governmental self-insured entities. In California, there are nearly 500 private (non-public entity) organizations that are self-insureds, although only 35 of them actually self-administer their claims. Self-administered entities are generally very large organizations with open claims often exceeding $100 million in estimated future liabilities (EFL). The remaining self-insureds, including many of the largest self-insureds, rely upon a state licensed Third Party Administrator (TPA) to provide these services. In California, 98 Third Party Administrators are currently licensed to provide these services, although some of these are dedicated units that serve a single self-insured client.
