(iii) Notice. On or before the filing date described in paragraph (c)(3)(ii) of this section, the controlling domestic shareholders shall provide written notice of the election made or the adoption or change of method or taxable year effected to all other persons known by them to be domestic shareholders who own (within the meaning of section 958(a)) stock of the foreign corporation. Such notice shall set forth the name, country of organization and U.S. employer identification number (if applicable) of the foreign corporation, and the names, addresses, and stock interests of the controlling domestic shareholders. Such notice shall describe the nature of the action taken on behalf of the foreign corporation and the taxable year for which made, and identify a designated shareholder who retains a jointly executed consent confirming that such action has been approved by all of the controlling domestic shareholders and containing the signature of a principal officer of each such shareholder (or its common parent). However, the failure of the controlling domestic shareholders to provide such notice to a person required to be notified shall not invalidate the election made or the adoption or change of method or taxable year effected.
