Gretchen W. McClain
Thank you, Phil. Good morning, everyone, and thank you for joining the call. We appreciate your interest in Xylem. I'll begin the call by providing you an update of our overall financial results for second quarter, then a few minutes updating on the progress we've made on our strategic objective and provide my perspective on our first half revenue performance and our full year outlook. I will also discuss the actions we're taking to address the continued economic uncertainty and positions us future growth. I'll then hand it over to Mike to walk through the details of our quarterly performance on our full year guidance.Today, we're reporting second quarter revenue of $966 million, reflecting growth of 4% on a constant currency basis. Organic growth was 1%, with acquisitions adding another 3%. While overall revenue were below our expectations for the quarter, our performance was on top of strong growth last year and in a more challenging environment. In Europe, where overall economic growth is negative, our revenues, on a constant currency basis, were down a modest 1%. And our continued focus an attractive acquisitions is helping us to drive top line growth. YSI added $32 million in revenue in the quarter and continued to outperform our expectations.
