International Rectifier Corp. said Wednesday it has received a three-month extension from the New York Stock Exchange for continued listing as the company prepares its earnings report for fiscal year 2007.

The Camarillo-based maker of high-efficiency computer chips now has until June 17 to file its annual report for the fiscal year ended June 30, 2007. If the company does not meet the deadline, the NYSE could extend the deadlines for an additional three months, the company said in a statement.

The company is still conducting an internal investigation into “unsubstantiated” sales that may have inflated sales numbers. The company’s former Chief Executive, Alex Lidow, resigned in October after the probe began. Oleg Khaykin was elected president and chief executive effective March 1.

International Rectifier shares fell 17 cents to $21.01 in morning trading.
