I believe that PVA is certainly looking to pull their executives away from day to day operations. Whether or not they choose to divest their holdings is another matter. The E&P industry is getting ready to get pounded over the next 2 years as natural gas prices remain low. Having large positions in the GP provides steady predictable cash in a time when receipts from gas sales will be low. On the otherhand, divesting the GP/MLP would garner a large amount of cash for them to weather the storm.
I personally believe they should hold onto PVG/PVR and allow Shea to grow the business.
Still don't believe me? Look what the company is doing to PVG. PVA is going to spin off PVR and PVG, I believe. PVA looks like they are getting out of the coal (and possible natural gas midstream) business.
