In my opinion ANR sellout may have a great impact on future EP as follows:
a. It will shorten to be the investmeent grade as much as one or two years.
b. It will make MLP spinning easier and make sense since both divisions attract different investors: Pipeline and stroage attracts stable and constant revenue mind investors while E&P does more aggresive ones.
c. To make easier to spinning with MLP, EP would start pay divident as WMB did as MLPed couple years ago.
My conclusion is this transaction will help long term investors tremendously. I would buy more if you can only if rumour is true.
