(a) Any domestic company may invest its funds as provided in this act and not otherwise. Notwithstanding the provisions of this act, the Insurance Commissioner may, after notice and hearing, order a domestic company to limit or withdraw from certain investments, or discontinue certain investment practices, to the extent that the commissioner finds that such investments or investment practices endanger the solvency of the company. The investments of a foreign company shall be as permitted by the investment laws of its state of domicile if such laws are substantially similar to that provided by this act.

(b) No investment or loan (except loans on life policies) or an investment practice shall be made or engaged in by any domestic company unless the same has been authorized or ratified by the board of directors or by a committee thereof charged with the duty of supervising investments and loans. No such company shall subscribe to or participate in any underwriting of the purchase or sale of securities or property or enter into any agreement to withhold from sale any of its property, but the disposition of its property shall be at all times within the control of the board of directors. Any agreement or contract providing for the lawful disposition of property, wherein such disposition may be determined at the option of a third person at some specified future price or condition or specified time or upon demand, shall be construed to be within the control of the board of directors. Nothing contained in this section shall prevent the board of directors of any such company from depositing any of its securities with a committee appointed for the purpose of protecting the interest of security holders or with authorities of any state or country where it is necessary to do so in order to secure permission to transact its appropriate business therein; and nothing contained in this section shall prevent the board of directors of such company from depositing securities as collateral for the securing of any bond required for the business of the company.

(c) Any domestic company subject to the provisions of this act is required to have a formal investment plan which shall be updated on an annual basis as authorized by the board of directors. The investment plan shall include, at a minimum, a description of the investment strategy of the company designed to provide for liquidity and diversity of the investment portfolio. The investment plan, and such other information as the Insurance Department may require in order to determine the impact of the investment plan on the solvency of the company, shall be made available to the Insurance Department during the course of a financial condition examination conducted in accordance with the laws pertaining to the conduct of examinations.
