Without prejudice to section 21, the grant of an option, and in particular—
is the disposal of an asset (namely of the option), but subject to the following provisions of this section as to treating the grant of an option as part of a larger transaction.
If an option is exercised, the grant of the option and the transaction entered into by the grantor in fulfilment of his obligations under the option shall be treated as a single transaction and accordingly—
The exercise of an option by the person for the time being entitled to exercise it shall not constitute the disposal of an asset by that person, but, if an option is exercised then the acquisition of the option (whether directly from the grantor or not) and the transaction entered into by the person exercising the option in exercise of his rights under the option shall be treated as a single transaction and accordingly—
The abandonment of—
shall constitute the disposal of an asset (namely of the option); but the abandonment of any other option by the person for the time being entitled to exercise it shall not constitute the disposal of an asset by that person.
This section shall apply in relation to an option binding the grantor both to sell and to buy as if it were 2 separate options with half the consideration attributed to each.
In this section references to an option include references to an option binding the grantor to grant a lease for a premium, or enter into any other transaction which is not a sale, and references to buying and selling in pursuance of an option shall be construed accordingly.
This section shall apply in relation to a forfeited deposit of purchase money or other consideration money for a prospective purchase or other transaction which is abandoned as it applies in relation to the consideration for an option which binds the grantor to sell and which is not exercised.
In subsection (4) above and sections 146 and 147—
If the Treasury by order so provide, an option of a description specified in the order shall be taken to be within the definition of "financial option" in subsection (8)(c) above.
