43. Secured creditors
(1) The following applies where a creditor alters the value of a security after a dividend has been declared.
(2) If the alteration reduces the creditor's unsecured claim ranking for dividend, the creditor must as soon as reasonably practicable repay to the Office-holder, for the credit of the administration or the insolvent estate, any amount received by the creditor as dividend in excess of that to which the creditor would be entitled, having regard to the alteration of the value of the security.
(3) If the alteration increases the creditor's unsecured claim, the creditor is entitled to receive from the Office-holder, out of any money for the time being available for the payment of a further dividend, before any such further dividend is paid, any dividend or dividends which the creditor has failed to receive, having regard to the alteration of the value of the security.
(4) However, the creditor is not entitled to disturb any dividend declared (whether or not distributed) before the date of the alteration.
