Maurice Ferré Thank you, Mark and good afternoon and thank you for joining us to discuss MAKO’s 2012 second quarter results. As a follow up to our selected Q2 operating results call on July 09, on today’s call, I'll provide you with some additional details on the operating results for the second quarter and Fritz will review the details of our financial results. I'd like to devote the balance of the call to discuss the current perspective on the business and operating priorities for the remainder of 2012. In the second quarter, we sold nine RIO systems of which eight were sold to domestic customers and one was sold for a customer to use to a prominent hospital in Hong Kong by our distributor in China. These nine RIO systems brings MAKO’s commercial installed base of RIO systems as of June 30, 2012, to 126 worldwide of which 123 systems are domestic. Of note, two of the systems sold in this quarter were sold to hospitals that are part of the Tenet Healthcare corporation, two are part of the Adventist Health Systems and one is part of the Community Health Systems.
