If you want to claim it this year. What you can do is sell your holding to a third (unrelated) party. You can sell it while hold it "on trust" for the buyer until such time the administrator allows for the shares to be transferred. If you Google for "how to sell worthless shares" you'll find a company that will buy them off you. You'll have to pay them a small fee to take your shares off you, so you've got to decide for yourself whether it's worthwhile "selling" now or wait until the liquidator declares your shares worthless.

Obviously this is just general information I have come across. This is NOT advice. You'll have to DYOR.
