Thank you, Valerie and good afternoon everyone. I am Mike Watts. I am Gen-Probe's Senior Director of Investor Relations. On behalf of Hank Nordhoff, our Chairman, President and CEO as well as Herm Rosenman, our Senior Vice President of Finance and CFO, as well as the rest of the Gen-Probe team, I am very pleased to welcome you to this conference call to discuss our fourth quarter 2007 business results. The press release announcing our results was issued today just after 4 o'clock Eastern Time and is posted on our website at www.gen-probe.com. In our call today, Hank will first provide an overview of our top line performance in the quarter, Herm will review our detailed results and initial 2008 guidance, then we'll take your questions. Before we begin, let me first review our Safe Harbor policy. Forward-looking guidance, financial or otherwise, is only provided in conference calls or in our press releases. Any statements in this conference call about our expectations, beliefs, plans, objectives, assumptions, or future events or performance are not historical facts and are forward-looking statements. These statements are often but not always made through the use of words and phrases such as believe, will, expect, anticipate, estimate, intend, plan, foresee, could, should and would. For example, statements concerning 2007 financial guidance, financial condition, regulatory approvals and timelines, possible or assumed future results of operations, growth opportunities, industry ranking and plans and objectives of management are all forward-looking statements. Forward-looking statements are not guarantees of performance. They involve known and unknown risks and uncertainties that may cause actual results to differ materially from those expressed or implied. Factors that might cause such differences include, but aren't limited to those discussed in our SEC filings including our report on Form 10-K for the year ended December 31st, 2006 and all subsequent periodic reports. Copies are available on our website at www.SEC.gov and on request from our Investor Relations department. Gen-Probe assumes no obligation and expressly disclaims any duty to update any forward-looking statements to reflect events or circumstances after the date of this call or to reflect the occurrence of unanticipated events. With that administrative detail out of the way, I will turn the call over to Hank Nordhoff, Gen-Probe's CEO.
