re: "Will this make our case difficult (or impossible) to prove?"
I would say, no. If anything seems to be missing, I think that the court can compell pxd to cough up info. I imagine a lot of seismic is farmed out to third party so there are probably plenty of useful records available. Not to mention woodside.
"Or do we have enough material without JPM's help?"
It's my impression that JPM hasn't been much help anyway so no net change there, more or less.
"BTW, I have had these units from my days with Mesa Pete and never thought they would be worth anything again. In fact, I forgot about them until last fall when I spotted a posting about this lawsuit. Never read the 10-Qs."
If you papered your wall with them, might consider getting one of those hand steamer gizmo's. <g>
They're probably going to get a lot more valuable real soon now. Bonus to the cause is that since you are holding certs, they can't be shorted by MM.
Just curious, the charts I can access don't appear to go back before electronic trading was the norm. I don't mean to be (too)nosy, but what were they valued at back then? Presumably more than they are trading for now?
