SEC Rule 144: Pledged Securities, Holding Periods and Subscriptions Agreements
Securities which are bona fide pledged may be tacked to the holding period of the pledgor as long as the pledge has full recourse against the pledgor. Gifted securities may be tacked with the holding period of the donor. Securities transferred to a trust may be tacked with the holding period of the settlor. Likewise securities transferred to a 401(k) or other individual retirement account will tack to the original issuance date. Securities obtained by beneficiaries of an estate may be tacked with the holding period of the deceased.
Securities acquired solely by the cashless exercise of an option or warrant are deemed to have been issued on the date of issuance of the underlying option or warrant; provided however, that the payment of any consideration, even a de minimus amount of cash, for the newly issued securities will restart the holding period. Accordingly, securities issued upon exercise of options or warrants in a stock option plan are deemed issued
