Call Schwab. I spent over an hour on the phone with the Cost Basis group walking through the details. Later in the morning, I got a callback and they think that I am right and the previous 1099-B was correct. They are investigating - nothing official at this time. Apparently, they started receiving calls yesterday from other people bewildered by the corrected 1099-B. My guess is that a new 1099-B will be issued reverting back to the previous 1099-B. At the time the person I was dealing with was not aware of the flood of calls about Shire.
However, I strongly recommend that you call Schwab and ask for the Cost Basis Group. You just have to mention Shire reporting.
