I also have a question regarding the 01/08/2019 merger between Shire and Takeda. 1099B was issued by Citibank. The acquisition of the Takeda shares is shown as a loss but the cost basis of the sale of the Shire shares is shown as $0. I called Citibank but rep claimed no tax accountants are on their staff and work is contracted out. Does anyone know if this $0 cost basis is correct, Shire stock is originally from Baxalta and Shire merger on 06/03/2016.
