Indiana Code Title 23. Business and Other Associations § 23-1-40-4

Sec. 4. (a) A parent corporation owning at least ninety percent (90%) of the outstanding shares of each class of a subsidiary corporation may merge the subsidiary and the parent corporation without approval of the shareholders of the parent or subsidiary.

(b) If the parent corporation will be the surviving corporation, the board of directors of the parent shall adopt a plan of merger that sets forth:

(c) The parent shall mail a copy or summary of the plan of merger to each shareholder of the subsidiary who does not waive the mailing requirement in writing.

(d) The parent may not deliver articles of merger to the secretary of state for filing until at least thirty (30) days after the date it mailed a copy of the plan of merger to each shareholder of the subsidiary who did not waive the mailing requirement.

(e) The articles of incorporation of the parent corporation that are in effect immediately before the effective date of the merger constitute the articles of incorporation of the surviving corporation, and articles of merger under this section may not contain amendments to the articles of incorporation of the parent corporation (except for amendments enumerated in IC 23-1-38-2).  If the subsidiary is a domestic corporation and will be the surviving corporation of a merger with a parent that is a foreign corporation, the articles of incorporation of the parent corporation that will be inherited by the subsidiary upon the effective date of the merger shall be delivered to the secretary of state for filing together with the articles of merger to be delivered for filing under section 5(a) of this chapter.

(f) If the parent corporation will not be the surviving corporation, the board of directors of the parent shall adopt a plan of merger that sets forth:

(g) A plan adopted under subsection (f) must ensure that each shareholder of the parent corporation whose shares were outstanding immediately before the effective date of the merger will hold the same proportionate number of shares relative to the number of shares held by all such shareholders (except for shares of the surviving corporation received solely as a result of the shareholder's proportionate shareholdings in any other corporations besides the parent which are parties to the merger), with identical designations, preferences, limitations, and relative rights, of the surviving corporation immediately after that effective date.  If the plan provides that the shareholders of the subsidiary (other than the parent) will not be shareholders of the surviving corporation immediately after that effective date, the plan must also set forth the manner and basis of converting the shares of the subsidiary held by such shareholders into obligations or other securities of the surviving corporation or shares, obligations, or other securities of any other corporation or into cash or other property in whole or in part.
