District of Columbia Abandonment of A Merger Or Share Exchange of Domestic For-Profit Corporation is a legal process in which a domestic for-profit corporation is allowed to abandon a merger or share exchange that was previously approved by the District of Columbia Board of Directors. This process allows the corporation to undo the merger or share exchange and return to its pre-merger or pre-exchange state. The process typically requires the filing of a petition with the District of Columbia Department of Consumer and Regulatory Affairs. There are two types of abandonment of a merger or share exchange of domestic for-profit corporation in the District of Columbia. The first type is a voluntary abandonment. This type of abandonment occurs when the shareholders of the merging or exchanging corporation vote to abandon the merger or share exchange. The second type is an involuntary abandonment, which occurs when the District of Columbia Board of Directors determines that the merger or share exchange is not in the best interests of the shareholders and the public. Both voluntary and involuntary abandonment of a merger or share exchange of domestic for-profit corporation require the filing of a petition with the District of Columbia Department of Consumer and Regulatory Affairs. The petition must include the reasons for the abandonment and the required supporting documents. Once the petition is filed, the Department of Consumer and Regulatory Affairs will review the petition and make a determination on the abandonment.
