Investors & landlords

 Thank you for your reply. Not sure that answers my question, because my tax basis was not zero. I had bought the EXC stock originally and through the years had paid taxes on the dividends. How could my basis be zero?  Also the new company only gave 1 (one) share for every 3 (three) shares of the old stock EXC.  I did receive

1099B for this non covered transaction whose basis I think was incorrect.
