a chargeable gain (“the original gain”) accrues on the disposal of shares (“the original shares”) to which deferral relief or relief under Chapter III of Part VII of the Taxes Act (EIS income tax relief), or both, is attributable;

the whole or part of the original gain is treated as not having accrued at the time of that disposal because of expenditure on shares being set against it under paragraph 2 of Schedule 5B; and

a chargeable gain (“the revived gain”) is subsequently treated as accruing in accordance with paragraph 4 of Schedule 5B as a result of the disposal (“the relevant disposal”) of shares expenditure on which has been set under paragraph 2 of Schedule 5B against the whole or part of the original gain or the whole or part of a gain derived from the original gain.
