(1) For the purpose of
section 421, the term “option” includes the right or privilege of an individual to purchase stock from a corporation by virtue of an offer of the corporation continuing for a stated period of time, whether or not irrevocable, to sell such stock at a price determined under
paragraph (d) of this section, such individual being under no obligation to purchase. Such right or privilege, when granted, must be evidenced in writing. The individual who has such right or privilege is referred to as the optionee and the corporation offering to sell stock under such an arrangement is referred to as the optionor. While no particular form of words is necessary, the written option should express, among other things, an offer to sell at the option price and the period of time during which the offer shall remain open.
(3) An arrangement between a corporation and an employee may involve more than one option. For example, if a corporation on June 1, 1954, grants to an employee the right to purchase 1,000 shares of its stock on or after June 1, 1955, another 1,000 shares on or after June 1, 1956, and a further 1,000 shares on or after June 1, 1957, all shares to be purchased before June 1, 1958, provided the employee at the time of exercise of any of the purchase rights is employed by the corporation, such an arrangement will be construed as the grant to the employee on June 1, 1954, of three options, each for the purchase of 1,000 shares. Similarly, if a corporation grants to an employee on January 1, 1955, the right to purchase 1,000 shares of its stock at $85 per share during 1955, or at $75 per share during 1956, or at $65 per share during 1957, such an arrangement will be construed as the grant to the employee on January 1, 1955, of three alternative options, one option for the purchase of 1,000 shares at $85 per share during 1955, an alternative option for the purchase of 1,000 shares at $75 per share during 1956, and a third alternative option for the purchase of 1,000 shares at $65 per share during 1957.
