When WiseTech director Charles Gibbon sold 1.53 million shares worth $200 million in December last year, it raised eyebrows because founder Richard White had (temporarily) left the company. But Gibbon, one of WiseTech’s earliest investors, assured tetchy shareholders it was for “personal estate planning purposes”.

The shares were sold by Fabemu No. 2 Pty Ltd, which acts as the trustee for the Gibbon Superannuation Fund for him and his wife. Selling from a self-managed super fund means Gibbon paid something like 10 per cent in capital gains tax. It’s a far lower rate than if he had sold them personally.
