The securities litigation law firm of Brower Piven, A Professional Corporation, has commenced an investigation into possible breaches of fiduciary duty and other violations of state law by the Board of Directors of Northern Tier Energy LP (NYSE: NTI) ("Northern Tier" or the "Company") relating to the proposed buyout of the Company by Western Refining, Inc. Under the terms of the agreement, Northern Tier shareholders are anticipated to receive $15.00 in cash and 0.2986 shares of Western Refining common stock for each share of Northern Tier common stock held, or approximately $25.99 per share. There are concerns regarding the price of the deal and the process by which the price was agreed upon. For example, according to Yahoo! Finance, at least one Wall Street analyst has issued a price target for Northern Tier stock at $34.00 per share. Moreover, the stock traded above the offer price within the past year. The firm's investigation seeks to determine, among other things, whether the Company's Board of Directors failed to satisfy their duties to shareholders, including whether the Board adequately pursued alternatives to the acquisition and whether the Board obtained the best price possible for the Company's shares of common stock. If you currently own common stock of Northern Tier and believe that the proposed buyout price is too low, or you would like to learn more about the investigation being conducted by Brower Piven, please visit our website at http://www.browerpiven.com/currentinvestigations.html.
