Investors & landlords

I will call the broker tomorrow and ask them about the cost basis.  I was strictly going by the CostBasis report that is a wizard for this exact merger with my information entered giving me the cost basis.  I know the loss at time of merger isn't allowed but examples I have looked at showing how to calculate cost basis when original merger is a loss shows it starting with the original basis of the stock you owned minus cash received.  Thank you both for all the help.  You have been extremely helpful.
