Timing of notice.
Timing of notice. The notice required by this paragraph (e)(4) must be delivered to the U.S. person on or before the later of the 120th day after the acquisition date of the particular target or the day on which Form 8023 is filed. The notice is considered delivered on the date it is mailed to the proper address (or an address similar enough to complete delivery), unless the date it is mailed cannot be reasonably determined. The date of mailing will be determined under the rules of section 7502. For example, the date of mailing is the date of U.S. postmark or the applicable date recorded or marked by a designated delivery service.
(v) Consequence of failure to comply. A statement of section 338 election is not valid if timely notice is not given to one or more U.S. persons described in this paragraph (e)(4). If the form of notice fails to comply with all requirements of this paragraph (e)(4), the section 338 election is valid, but the waiver rule of § 1.338-10(b)(1) does not apply.
(vi) Good faith effort to comply. The purchasing corporation will be considered to have complied with this paragraph (e)(4), even though it failed to provide notice or provide timely notice to each person described in this paragraph (e)(4), if the Commissioner determines that the purchasing corporation made a good faith effort to identify and provide timely notice to those U.S. persons.
