This is why. TPL has held "perpetual non-participating royalty acreage" for a long time. This entitles the owner a royalty interest of oil & gas production without ever having to put up any money. TPL used to state that when surface lands were sold TPL would retain the mineral rights. SO WHEN MANAGEMENT SUDDENLY SELLS OFF A PORTION OF THOSE PERPETUAL RIGHTS ONE WANTS TO KNOW WHY! Does anyone really believe managements story that they only traded lands with Chevron which resulted in a much better deal for TPL! So TPL's two trustees outwitted Chevron, with all of its petroleum engineers into giving them a much better deal? That's laughable! For starters it was understood that TPL would never sell off its mineral rights. Why sell off the very heart of your operation? Because Chevron will give you better land in return? Isn't that what TPL management wants us to believe?
