An insurance firm must maintain sufficient capital to enable it to meet at all times its insurance and other obligations. The minimum Tier 1 capital for insurance firms is BD 5 million, except for those firms whose business is limited to reinsurance. Insurance firms whose business is limited to reinsurance must have minimum Tier 1 capital of BD 10 million. Captive insurance firms are not subject to a minimum Tier 1 capital but must comply with the Required Solvency Margin and minimum fund, as defined in Chapter CA-2. In addition, all insurance firms must at all times maintain a capital available in excess of the greater of the Required Solvency Margin and the minimum fund, as defined in Chapter CA-2.
