And now, here's Tim.Timothy E. Guertin Good afternoon, and welcome. Today, we're reporting results for the second quarter of 2012 with healthy growth in revenue, net orders and backlog but with mixed margin results. Earnings were $0.94 including a $0.02 restructuring charge associated with the realignment of resources to support our ongoing growth in emerging markets. I will comment on the operational highlights for the quarter as well as our exciting newly announced global collaboration with Siemens, and Elisha will walk you through the numbers. To summarize our second quarter 2012 results compared to the year-ago quarter, company revenues for the quarter rose by 11% to $720 million. Net orders were up nicely in all of our businesses and our backlog increased by 18% to $2.7 billion. Excluding proton, order backlog was up 12%.
