Kirby McInerney LLP is investigating potential claims against the Board of Directors of Power-One, Inc. ("Power-One" or the "Company") (NASDAQ: PWER) related to the proposed acquisition of the Company by ABB Ltd. ("ABB"). Under the terms of the proposal, ABB will acquire all of the outstanding common stock of Power-One for $6.35 per share in cash, for a total transaction value of approximately $1 billion, which includes Power-One's net cash holdings of $266 million.

The investigation concerns whether the Power-One Board of Directors violated its fiduciary duties by agreeing to this transaction and whether the proposed $6.35 per share consideration adequately values Power-One common shares.
