Upon the sale or exchange of property the entire amount of the gain or loss, determined under section fourteen, shall be recognized, except as hereinafter provided in this section:
The term "reorganization" means (a) a merger or consolidation (including the acquisition by one corporation of at least a majority of the voting stock and at least a majority of the total number of shares of all other classes of stock of another corporation, or substantially all the properties of another corporation), or (b) a transfer by a corporation of all or a part of its assets to another corporation if immediately after the transfer the transferor or its stockholders or both are in control of the corporation to which the assets are transferred, or (c) a recapitalization, or (d) a mere change in identity, form or place of organization, however effected;
The term "a party to a reorganization" includes a corporation resulting from a reorganization and includes both corporations in the case of an acquisition by one corporation of at least a majority of the voting stock and at least a majority of the total number of shares of all other classes of stock of another corporation; and
The term "control" means the ownership of at least eighty per centum of the voting stock and at least eighty per centum of the total number of shares of all other classes of stock of the corporation.
If such transfer of all the property does not occur within the year, the director of finance may require of the taxpayer such bond, or waiver of the statute of limitations on assessment and collection, or both, as he may deem necessary to insure, if the transfer of the property is not completed within such three year period, or if the taxpayer does not continue qualified under paragraph (a) until the completion of such transfer, the assessment and collection of all taxes then imposed under this subpart for such year or subsequent years, to the extent attributable to property so received. A distribution otherwise constituting a distribution in complete liquidation within the meaning of this paragraph shall not be considered as not constituting such a distribution merely because it does not constitute a distribution or liquidation within the meaning of the corporate law under which the distribution is made; and for the purposes of this paragraph a transfer of property of such corporation to the taxpayer shall not be considered as not constituting a distribution (or one of a series of distributions) in complete cancellation or redemption of all the stock of such corporation, merely because the carrying out of the plan involves (1) the transfer under the plan to the taxpayer by such corporation of property, not attributable to shares owned by the taxpayer, upon an exchange described in subdivision three of this section, and (2) the complete cancellation or redemption under the plan, as a result of exchanges described in subdivision two of this section, of the shares not owned by the taxpayers.
