1) I and others have repeated the 2:1 issue when dealing in price numerous times over a month ago. (In fact even before teh spin happened.)
2) If you will note, in my post you responded to never did I deal in share price it was all referring to a value basis. As such the 1/2 factor is already included. Though I will say that for all my lots, I have calculated a per share adjusted cost basis and that is much more practicable to use XX years from now.
