California Self-Insurance Plans (SIP) Practice Exam

In a SIP setup, ER stands for Employer. The employer is the sponsor and funding source of the self-insured program, responsible for funding the plan, appointing the claims administrator, and ensuring compliance with applicable laws. This usage contrasts with terms referring to employees or other functions, which don’t align with the role of the party that ultimately bears the financial risk and oversight of the self-insured arrangement. So the best answer is Employer because it matches the typical designation of the party that administers and funds the SIP.
