Bernstein Liebhard LLP is investigating whether the Board of Directors of Encore Energy Partners LP (“Encore” or the “Company”) (NYSE: ENP) breached its fiduciary duty to its shareholders in agreeing to sell Encore to Vanguard Natural Resources, LLC (“Vanguard”).

Under the terms of the agreement, Encore shareholders will receive 0.75 Vanguard common units in exchange for each Encore common unit they own at closing. The investigation is focused on the potential unfairness of the price to Encore shareholders and the process by which the Encore Board of Directors considered and approved the transaction.

If you are interested in discussing your rights as an Encore shareholder and/or have information relating to the matter, please contact U. Seth Ottensoser at (877) 779-1414 or Ottensoser@bernlieb.com.
