Bruce.....Sheer Speculation on all of these but.......What if.....
1) Israeli Prime Minister did not like the results or how Viking was performing ? 2) ZN did not like the results of how Viking was performing ? 3) Viking did not like the way ZN or Israeli Oil Minister was performing? 4) Viking sees no future with ZN or Israeli Oil ? 5) ZN might be see the separation as a cost savings? 6) Israeli Oil Minister is getting kick back from ZN to continue ?
Bruce.... I bet you have 60 of these reasons at least....and I bet yours are closer than mine on the truth, but ZN will probably continue to hold their cards close.
I'm getting ready to go on a sabbatical and not visit this board so often. A watched pot never boils.
