by virtue of section 144(2) of the 1992 Act, the grant of an option binding the grantor to sell an interest in UK land is, on the exercise of the option, treated as the same transaction as the sale, and

both the grant of the option and the transaction entered into by the grantor in fulfilment of the grantor's obligations under the option (“the sale”) would be non-resident CGT disposals (were they not treated as a single transaction).

the grantor is to be subject to the same obligations under sections 12ZB, 12ZE and 59AA (duties relating to returns and payments on account) in relation to the grant of the option as the grantor would be subject to were the option never to be exercised, and

the consideration for the option is to be disregarded (despite section 144(2) of the 1992 Act) in calculating under section 12ZF the amount of capital gains tax notionally chargeable at the completion date of the single transaction mentioned in subsection (1)(a).
