Example (1).
X Corporation is a subsidiary of S Corporation which, in turn, is a subsidiary of P Corporation. On June 1, 2004, P grants to an employee of P a statutory option to purchase a share of stock of X. On January 1, 2005, S sells a portion of the X stock which it owns to an unrelated corporation and, as of that date, X ceases to be a subsidiary of S. Because X was a subsidiary of P on the date of the grant of the statutory option, the option does not fail to be a statutory option even though X ceases to be a subsidiary of P.
Example (2).
Assume P grants an option to an employee under the same facts as in example (1) above, except that on June 1, 2004, X is not a subsidiary of either S or P. Such option is not a statutory option on June 1, 2004. On January 1, 2005, S purchases from an unrelated corporation a sufficient number of shares of X stock to make X, as of that date, a subsidiary of S. Because X was not a subsidiary of S or P on the date of the grant of the option, the option is not a statutory option even though X later becomes a subsidiary of P. See §§ 1.422-2(a)(2) and 1.423-2(b).
Example (1).
On June 1, 2004, X Corporation granted a statutory option to A, an employee of X Corporation, to purchase a share of X stock. On February 1, 2005, X sold the plant where A was employed to M Corporation, an unrelated corporation, and A was employed by M. If A exercises his statutory option on June 1, 2005, section 421 is not applicable to such exercise, because on June 1, 2005, A is not employed by the corporation which granted the option or by a related corporation of such corporation, nor was he employed by any of such corporations within 3 months before June 1, 2005.
Example (2).
Assume the facts to be the same as in example (1), except that when A was employed by M Corporation, the option to purchase X stock was terminated and was replaced by an option to buy M stock in such circumstances that M Corporation is treated as a corporation substituting an option under section 424(a). If A exercises the option to purchase the share of M stock on June 1, 2005, section 421 is applicable to the transfer of the M stock because, at all times during the period beginning with the date of grant of the X option and ending with the date of exercise of the M option, A was an employee of the corporation granting the option or substituting or assuming the option under § 1.424-1(a).
Example (3).
E is an employee of P Corporation. On June 1, 2004, P grants E a statutory option to purchase a share of P stock. On June 1, 2005, P acquires 100 percent of the stock of S Corporation; on such date S becomes a subsidiary of P. On July 1, 2005, E ceases to be employed by P and becomes employed by S. On October 10, 2005, while still employed by S, E exercises his option to buy P stock. Since E was at all times during the requisite period of employment an employee of either P, the corporation granting the option, or S, a subsidiary of the grantor during the period in which such corporation was E's employer, section 421 is applicable to the exercise of the option.
Example (4).
Assume the same facts as in example (3) except assume that at the time E became an employee of S Corporation, S assumed E's option to purchase P stock under section 424(a). Section 421 is applicable to E's exercise of his option to buy P stock.
Example (5).
M Corporation grants a statutory option to E, an employee of such corporation. E is an officer in a reserve Air Force unit. E goes on military leave with his unit for 3 weeks. Regardless of whether E is an employee of M within the meaning of section 3401(c) and the regulations thereunder during such 3-week period, E's employment relationship with M is treated as uninterrupted during the period of E's military leave.
Example (6).
Assume the same facts as in example (5) and assume further that E's active duty status is extended indefinitely, but that E has a right to reemployment with M or a related corporation on the termination of any military duty E may be required to serve. E exercises his M option while on active military duty. Irrespective of whether E is an employee of M or a related corporation within the meaning of section 3401(c) and the regulations thereunder at the time of such exercise or within 3 months before such exercise, section 421 applies to such exercise.
Example (7).
X Corporation grants an incentive option to A, an employee of X Corporation, whose employment contract provides that in the event of illness, A's right to reemployment with X, or a related corporation of X, will continue for 1 year after the time A becomes unable to perform his duties for X. A falls ill for 90 days. For purposes of section 422(a)(2), A's employment relationship with X will be treated as uninterrupted during the 90-day period. If A's incapacity extends beyond 90 days, then, for purposes of section 422(a)(2), A's employment relationship with X will be treated as continuing uninterrupted until A's reemployment rights terminate. Under section 422(a)(2), A has 3 months in which to exercise an incentive option after his employment relationship with X (and related corporations) is deemed terminated.
