Here's a few key points from a fact sheet they posted on their website relating to a previous capital return by AMP Ltd - tax consequences of a capital return by WPG would be similar...

Are there any tax consequences for me?

- As a result of the return of capital, you must adjust the cost base and reduced cost base of your shares.

- The capital return on your shares is a capital gains tax (CGT) event that may have resulted in a capital gain for you. Depending on the outcome, you may have to include some details on your tax return.

Did I make a capital gain?

You have made a capital gain if your cost base per share on the payment date was less than the amount you received for each share.
