EL SEGUNDO, Calif.--(BUSINESS WIRE)--Sept. 10, 2008--International Rectifier Corporation (NYSE:IRF) today urged shareholders to take no action with respect to the unsolicited proposal announced today by Vishay Intertechnology (NYSE:VSH) to acquire all of the outstanding shares of International Rectifier common stock for $23.00 per share in cash.

Richard Dahl, the Chairman of the Board of IR, commented: "We will, as we have in the past, carefully review Vishay's proposal in consultation with our financial and legal advisors, Goldman, Sachs & Co. and Fried, Frank, Harris, Shriver & Jacobson, LLP, respectively. We wish to clarify that we have not entered into negotiations with Vishay because it had submitted, until today, only one proposal, for $21.22 per share on August 14, that was rejected by our Board. The Board declined subsequent requests for negotiations since there was no change in a proposal that our Board had determined was opportunistic, inadequate and not in the best interests of the Company and its shareholders."
