They currently hold ~$12k USD of mine and have not responded to support requests or emails in over a month.  $10k of that USD had been requested as withdrawals via wire transfer BEFORE they announced their shutdown and were in the "Booked" (pending) state.

They did however return all of my BTC (~240 BTC) that was in my account on 11/19 and 11/28.  The BTC withdrawal requests were made upon their announcement to shut down but the transfers on 11/28 were not processed until I emailed and complained:

I suspect they are insolvent.
