All assigned carriers are required to report their experience on business written under the Plan to the Administrator in a format prescribed by the Council. It is the responsibility of the Plan Administrator to monitor both rate adequacy and Plan results. The Plan Administrator shall notify the Commissioner if excessive losses are indicated to enable the Commissioner to take corrective action.
