Extensions
(C) Extensions(1) In general. An extension of a stock right refers to the provision to the holder of an additional period of time within which to exercise the stock right beyond the time originally prescribed under the terms of the stock right, the conversion or exchange of a stock right for a legally binding right to compensation in a future taxable year, or the addition of any feature for the deferral of compensation not permitted in paragraph (b)(5)(i)(A)(3) of this section (in the case of a stock option) or not permitted in paragraph (b)(5)(i)(B)(3) of this section (in the case of a stock appreciation right) to the terms of the stock right, other than at a time when the exercise price of the stock right equals or exceeds the fair market value of the service recipient stock that could be purchased (in the case of an option) or the fair market value of the service recipient stock used to determine the payment to the service provider (in the case of a stock appreciation right), and includes a renewal of such right that has such effect. It is not an extension if the exercise period of a stock right is extended to a date no later than the earlier of the latest date upon which the stock right could have expired by its original terms under any circumstances or the 10th anniversary of the original date of grant of the stock right. If the exercise period of a stock right is extended at a time when the exercise price of the stock right equals or exceeds the fair market value of the service recipient stock that could be purchased (in the case of an option) or the fair market value of the service recipient stock used to determine the payment to the service provider (in the case of a stock appreciation right), it is not an extension of the original stock right. Instead, in such a case, the original stock right is treated as modified rather than extended and a new stock right is treated as having been granted for purposes of this section. In addition, it is not an extension of a stock right if the expiration of the stock right is tolled while the holder cannot exercise the stock right because such an exercise would violate an applicable Federal, state, local, or foreign law, or would jeopardize the ability of the service recipient to continue as a going concern, provided that the period during which the stock right may be exercised is not extended more than 30 days after the exercise of the stock right first would no longer violate an applicable Federal, state, local, and foreign laws or would first no longer jeopardize the ability of the service recipient to continue as a going concern. For this purpose, a provision of foreign law shall be considered applicable only to foreign earned income (as defined under section 911(b)(1) without regard to section 911(b)(1)(B)(iv) and without regard to the requirement that the income be attributable to services performed during the period described in section 911(d)(1)(A) or (B)) from sources within the foreign country that promulgated such law.
