Description of regulatory capital requirement |
|
|
American National Insurance Company’s payment of dividends to stockholders is restricted by insurance law. The restrictions require life insurance companies to maintain minimum amounts of capital and surplus, and in the absence of special approval, limit the payment of dividends to the greater of the prior year’s statutory net income from operations, or 10% of prior year statutory surplus.
