(4)Subsection (2) above shall not apply unless the price obtained on the sale, with any adjustment needed to take account of any difference in circumstances at the date of the sale and at the date of the death, is less than the value which, apart from this section and apart from Chapter IV of this Part of this Act, would be the value of the property concerned determined as mentioned in subsection (1) above.
(5)Where the property concerned consists of shares in or securities of a close company, subsection (2) above shall not apply if at any time between the death and the qualifying sale the value of the shares or securities is reduced by more than 5 per cent as a result of an alteration in the company’s share or loan capital or in any rights attaching to shares in or securities of the company; and for the purposes of this subsection—
