Our second quarter results were in-line with our expectations, and reflect the period of significantly reduced spending from our largest Storage Infrastructure customer as it continues to integrate capital equipment acquired as a result of its recent acquisition. We did a good job of executing to our strategic plans and customer expectations. I am encouraged with regard to our continued progress in expanding our customer base as well as our efforts in accessing new markets for our capital equipment, said Steve Barber, CEO of Xyratex. Despite some challenging customer requirements, I am confident that the fundamentals of the markets we serve continue to remain good and believe we continue to improve on our competitive and technology position.
