**5.2 2015 Overhaul**

Accordingly, the Steering Committee of the system began deliberation over the review of the system in February 2012. The committee conducted fact-finding research including the collection and analysis of population-based data on the incidence of cerebral palsy, which is necessary for estimating the number of eligible patient and is crucial for re-designing the system. The results were reported to the Steering Committee in July 2013, and the committee and the Medical Insurance Subcommittee of the Social Security Council of the MHLW reviewed to revamp the system in terms of the scope of eligibility, the amount of monetary compensation, the price of insurance premium, and the way to spend surplus that had aggregated

since the launch of the system. The review concluded that the system expanded the scope of eligibility with the same amount of monetary compensation to be applied in January 2015 and later. As to how to spend growing surplus, the Medical Insurance Subcommittee agreed that the insurance premium was reduced to the price that work with the surplus to sustainably ensure budget for compensation. It was planned that the surplus was spent for the next 10 years by 2024 to consume it.
