Kieran T. Gallahue, President and Chief Executive Officer, commented, "In the third quarter of fiscal 2009, we continued to show strong growth year over year. Our favorable mix of product sales and market share gains led to a 23% increase in the Americas over the prior year quarter resulting in $122.5 million in revenue. As expected, sales outside the Americas were impacted by currency movements, in particular the depreciation of the Euro against the U.S. dollar. As a result, sales outside the Americas decreased by 6% to $105.4 million, but were up 10% in constant currency terms. Cash flow from operations for the March 2009 quarter was a strong $44.2 million.
"Our gross margin also expanded in Q3. This was a result of an increase in sales of our higher margin products, the depreciation of the Australian dollar and continued efforts to leverage cost efficiencies across our global organization. The market continues to respond well to our full range of products. The Easy Breathe motor technology has set a new standard in performance.
