I don't have my notes with me, and wasn't going to post a supplement until later, but with the non-trading situation, I'll include the following.
At the AGM, there was a recap of the events that led to the halt trade. In Feb 09, the exchange informed MEO that it was under a higher level of scrutiny. Additional information related to the last year-end financials was requested, which were believed, by the CFO, to have an impact on the next quarterly filing, so it wasn't submitted. This belief was wrong, and the deadline passed for filing, and the halt was ordered. MEO is now interviewing for a new CFO.
Not pretty, but not end of the world either.
