Indiana Code Title 27. Insurance § 27-1-8-12

Sec. 12. A company may amend its articles by providing for a decrease of its capital stock to an amount not less than the minimum capital required for the kind or kinds of insurance transacted by the company before the amendment of the company's articles of incorporation.  The department shall not approve or issue its certified copy of such amendment to the company if it shall be of the opinion that the interests of policyholders or creditors may be prejudiced thereby.  No distribution of the assets of the company shall be made to shareholders upon any such decrease of capital which shall reduce the surplus of its assets over its liabilities, including capital, to less than the minimum surplus required by this article.  Upon any such amendment so decreasing the capital, such company may require each shareholder to return the shareholder's certificate of stock and accept a new certificate for such proportion of the amount of its original stock as the reduced capital shall bear to the original capital.
