I found the following article interesting with the opinions of several analysts instead of a single consensus opinion:

It puts the ML lime break even in the mid 80's.  Obviously this is an average with some companies much better and some much worse.  From all the data , AOK is significantly better.  However anyone taking a superficial look at things would probably reduce exposure to the ML (relative to other fields) and this may account for some of the pull back.

It also has implications on valuation - ML acres are not as valuable.  I don't think this has has a huge impact on AOK since most of its valuation is based on production / NPV (acres are quite small).  In fact, if they are leasing more acres, this could be quite beneficial with negotiations.  Same story for drilling services, etc - could be a buyer's market.
