The Office of Self-Insurance Plans (OSIP) authorizes qualified employers to provide their own coverage for workers' compensation liabilities. Small and medium-sized businesses have the option of joining with others in the same industry to self-insure their workers' compensation liability as a group. All Self-Insurance Groups (SIGs) must be approved by OSIP and are required to post a security deposit covering their actuarial determined liabilities. California has one of the largest self-insurance programs in the nation and has some of the strongest regulations designed to ensure the system protects both employers and employees.
