The net for Treaty should be around 40% after Princess and the GOB, unless the GOB agreement only calls for 10% for the first few thousand barrels, which foreign countries sometimes discount their tax rate to encourage more development.  You are correct regarding Princess and Treaty, they do split 50/50, after the GOB.  Good question...  And it seems like your vacation agreed with you.  Now, it's time to get back to honey-dos and some football.
