RE:RE:Libya shutting down second field, Crude jumpsauto you have hit on something which over the years has been a pet peeve of mine - especially when I was in the investment business.
Companies are obligated under securities law to report on event which have a "material impact" on their operations. In addition, the time for reporting such an incident is vague. In addition to this, "material impact" is not clearly defined.
When put together, this means that companies have great deal of latitude as to what they report.
In the case of SU, I suspect that they have determined that their Lybian assets are not affected by the developments there...or..if they do, it is not a material event.
Given, arguably, that SU has had its share of bad news, I suspect that they have determined that what is going on in Lybia is not a materlal event and so they are mum on the subject.
When things like that happen is up to investors like yourself who actually do a bit homework to share with others. Good for you!!
