Private stock

Hi,
In year 2000 I bought private stock in Hush Communications(you can google them). I paid $25,000 for 12,007 shares of Series C preferred stock. I received a certificate stating that fact and also stating the the stock had a .001 value at that time. The company is still operating but still private and I receive an operating report twice a year. I have called them to try and sell back the stock and they know of no one wanting to buy the stock from me.
I would like to abandon the stock to them. I would sign the certificate over to them and ask for no consideration. Could I then get a 2012 federal tax loss on my $25,000 investment made in 2001 due to my abandonment of stock? . Thanks, Jano18

 

Is this question that I asked that difficult? Thanks
