This document is about analyzing the Form 5500 data on self-insured group health plans in the United States. It provides insights into the distribution of funding mechanisms (self-insured, fully insured, and mixed-funded) across health plans and plan participants, as well as how these funding mechanisms vary by plan size, employer type, and financial health of the plan sponsor. The report also examines trends in the prevalence of stop-loss coverage among self-insured and mixed-funded plans.
