Description of minimum requirement of solvency applicable | If the insurance company’s solvency ratio is less than 100%, it indicates that the solvency standard amount measured by the potential loss amount cannot be covered with capital, which means that the insurance company’s capital soundness has become poor, and the supervisory authority must comply with the Regulations on Supervision of Insurance Business. Accordingly, insurance companies with a solvency ratio of less than 100% are required to take timely corrective actions such as management improvement recommendations, management improvement requests, or management improvement orders. |
