Based on everything that I have seen - my guess is you will have very little loss to claim. ....maybe you may even show a gain !!
I don't recall paying any tax on OPL stock. (??) If you purchased 4 shares of UPS stock you received 1 share of OPL. You can't claim a loss on monies that were not cashed in.
If you didn 't pay for the share how do you claim a loss??? You will need to prove the cost basis of the stock and subtract the cost basis from the sale price to show either a gain or a loss. I am pretty sure it is all gain.
Your UPS incentive shows as income and you pay taxes on it.... therefore you can establish a cost basis on each share.

There is a letter there that shows calculation based on 10,000 shares; you will have $128 of ordinary income to declare ....
