anjouan,
Have a look at today's thread about the CEO of OLOG being fired and the CFO resigning, along with the speculation about it possibly having to do with Nigeria. Remember the other comment about how Bristow and Pan African are operating for large companies like Exxon/Mobil and Chev/Tex and these big American oil companies don't like a nasty whiff of scandal involving bribery and corruption.
If you're in a position to wait, I'd just see what CHC are going to do about the pay in ACN and see if this OLOG scandal has any fallout in Nigeria. It should become obvious fairly quickly
