writeoff stock loss bankrupt co. but stock not sold

My Webvan (symbol: wbvn) investment is a total loss, but I still own the stock. It went belly up in 2001. It's listed on my statement from my broker at .001/share. Can I deduct this loss in 2001 (fed return), or is there some other transaction that I must first complete, in order to get it off my books?

If I can deduct it, how? What form? Obviously, it's not a sale.

TIA

Your transaction is not a sale, but you should treat it as a sale for $0 on Sch D. Indicate on the form that the stock became worthless. Your loss equals your basis for the stock.
