17 CFR § 240.16a-6 - Small acquisitions.
(a) Any acquisition of an equity security or the right to acquire such securities, other than an acquisition from the issuer (including an employee benefit plan sponsored by the issuer), not exceeding $10,000 in market value shall be reported on Form 5, subject to the following conditions:
(1) Such acquisition, when aggregated with other acquisitions of securities of the same class (including securities underlying derivative securities, but excluding acquisitions exempted by rule from section 16(b) or previously reported on Form 4 or Form 5) within the prior six months, does not exceed a total of $10,000 in market value; and
(2) The person making the acquisition does not within six months thereafter make any disposition, other than by a transaction exempt from section 16(b) of the Act.
(b) If an acquisition no longer qualifies for the reporting deferral in paragraph (a) of this section, all such acquisitions that have not yet been reported must be reported on Form 4 before the end of the second business day following the day on which the conditions of paragraph (a) of this section are no longer met.
