16 C.F.R. § 801.30
(a) This section applies to:
(7) Acquisitions of voting securities resulting from the exercise of options or warrants which are—
(b) For acquisitions described by paragraph (a) of this section:
(2) The acquired person shall file the notification required by the act, in accordance with these rules, no later than 5 p.m. Eastern Time on the 15th (or, in the case of cash tender offers, the 10th) calendar day following the date of receipt, as defined by § 803.10(a), by the Federal Trade Commission and Assistant Attorney General of the notification filed by the acquiring person. Should the 15th (or, in the case of cash tender offers, the 10th) calendar day fall on a weekend day or federal holiday, the notification shall be filed no later than 5 p.m. Eastern Time on the next following business day.
Examples:1. Acquiring person “A” proposes to acquire from corporation B the voting securities of B's wholly owned subsidiary, corporation S. Since “A” is acquiring the shares of S from its parent, this section does not apply, and the waiting period does not begin until both “A” and “B” file notification. 2. Acquiring person “A” proposes to acquire in excess of $50 million (as adjusted) of the voting securities of corporation X on a securities exchange. The waiting period begins when “A” files notification. “X” must file notification within 15 calendar days thereafter. The seller of the X shares is not subject to any obligations under the act.3. Suppose that acquiring person “A” proposes to acquire 50 percent of the voting securities of corporation B which in turn owns 30 percent of the voting securities of corporation C. Thus “A's” acquisition of C's voting securities is a secondary acquisition (see § 801.4) to which this section applies because “A” is acquiring C's voting securities from a third party (B). Therefore, the waiting period with respect to “A's” acquisition of C's voting securities begins when “A” files its separate Notification and Report Form with respect to C, and “C” must file within 15 days (or in the case of a cash tender offer, 10 days) thereafter. “A's” primary and secondary acquisitions of the voting securities of B and C are subject to separate waiting periods; see § 801.4.
