Bernstein Liebhard LLP is investigating whether the Board of Directors of Power-One, Inc. (“Power-One” or the “Company”) (NASDAQ: PWER) breached its fiduciary duty to its shareholders in agreeing to sell Power-One to ABB (NYSE: ABB).

Under the terms of the agreement, Power-One shareholders will receive $6.35 in cash for each share they own.  The investigation is focused on the potential unfairness of the price to Power-One shareholders and the process by which the Power-One Board of Directors considered and approved the transaction.
