140.-Further interpretation of sections 135 to 139.

(1) For the purposes of section 135, 136, 138 or 139, a right to acquire shares is obtained by a person as a director or employee (within the meaning of the section in question) of a body corporate-

(a) if it is granted to him by reason of his office or employment as such a director or employee who is chargeable to tax in respect of that office or employment under Case I of Schedule E; or
(b) if the right is assigned to him and was granted by reason of any such office or employment of his to some other person;

and paragraph (a) above shall apply to a right granted by reason of a person's office or employment after he has ceased to hold it if it would apply to a right so granted in the last chargeable period in which he did hold it.
(2)
For those purposes any question whether a person is connected with another shall be determined in accordance with section 839.
(3)
For those purposes-

"market value" has the same meaning as, for the purposes of the [1992¹⁶] Act, it has by virtue of section [272¹⁶] of that Act; and
"securities" has the meaning given by section 254(1).
