OK I understand that. That was an average cost basis for the entire position at one point when they held 907m shares. I was using the cost basis for the actual shares sold during the 2nd quarter.

I don't remember if the shares sold in the first quarter were higher basis or lower than the q2 sold shares. Usually I would assume he would sell higher basis shares first and defer the lowest basis shares the longest - but he has some opinion on the future of corporate tax rates so he may think about it differently.
