Where a document is omitted pursuant to paragraph (a) of this section, but information relating to the subject matter of such document is nevertheless included in material filed with the Commission pursuant to a determination of an appropriate department or agency of the United States that disclosure of such information would not be contrary to the interests of national defense or foreign policy, a statement from such department or agency to that effect shall be submitted for the information of the Commission.
