(1) All dividends on shares of a corporation forming a part of the principal, which shares are payable in the identical class of the shares of the corporation as the stock on which the dividend is paid, shall be deemed principal. Subject to the provisions of this section, all dividends payable otherwise than in such identical class of the shares of the corporation itself, including ordinary and extraordinary dividends and dividends payable in other shares or in other securities or in obligations of corporations other than the declaring corporation, shall be deemed income. Except with respect to investment trusts, regulated investment companies, and trusts qualifying and electing to be taxed under federal law as real estate investment trusts, where the trustees have the option of receiving a dividend either in cash or in the shares of the declaring corporation, it shall be considered as a cash dividend and deemed income, irrespective of the choice made by the trustee. Distributions made from ordinary income by an investment trust, by a regulated investment company, or by a trust qualifying and electing to be taxed under federal laws as a real estate investment trust shall be deemed income. All other distributions made by the company or trust, including distributions from capital gains, depreciation, or depletion, whether in the form of cash or an option to take new stock or cash or an option to purchase additional shares, shall be deemed principal.

(2) All rights to subscribe to the shares or other securities or obligations of a corporation accruing on account of the ownership of shares or other securities in such corporation and the proceeds of any sale of such rights shall be deemed principal. All rights to subscribe to the shares or other securities or obligations of a corporation accruing on account of the ownership of shares or other securities in another corporation, and the proceeds of any sale of such rights, shall be deemed income.

(3) Where the assets of a corporation are wholly or partially liquidated, amounts paid upon corporate shares as cash dividends declared before such liquidation occurred or as arrears of preferred or guaranteed dividends shall be deemed income; all other amounts paid upon corporate shares on disbursement of the corporate assets to the stockholders shall be deemed principal.

(4) If a corporation succeeds another by merger, consolidation, or reorganization or otherwise acquires its assets and the corporate shares of the succeeding corporation are issued to the shareholders of the original corporation in like proportion to, or in substitution for, their shares of the original corporation, the two corporations shall be considered a single corporation in applying the provisions of this section, but two corporations shall not be considered a single corporation under this section merely because one owns corporate shares of or otherwise controls or directs the other.

(5) In applying this section, the date when a dividend accrues to the person who is entitled to it shall be held to be the date specified by the corporation as the one on which the stockholders entitled thereto are determined, or, in default thereof, the date of declaration of the dividend.

(6) All disbursements of corporate assets to the stockholders, whenever made, which are designated by the corporation as a return of capital or division of corporate property shall be deemed principal.

(7) Any distribution of shares or other securities or obligations of a corporation, other than the distributing corporation, or the proceeds of sale or other disposition thereof, made as a result of a court decree or final administrative order by a governmental agency ordering the distributing corporation to divest itself of the shares, securities, or other obligations, shall be deemed principal unless the distributing corporation designates that the distribution is wholly or partly in lieu of an ordinary cash dividend, in which case the distribution, to the extent that it is in lieu of the ordinary cash dividend, shall be deemed income. The provisions of this subsection (7) shall take effect on or after March 13, 1963, and shall apply to all estates of tenants or remaindermen then legally effective, whenever created, as well as to all estates of tenants or remaindermen which become legally effective thereafter.
