Yes, I think we're relatively comfortable with where the revenue synergies are, quite frankly. Again, I think that, as we've stated time and time again, this Quest deal would never have happened had Hologic and Gen-Probe not been combined. And I think we're seeing that portfolio component, that portfolio sale being replicated at all segments of the market right now. We're going again [ph] , and we're talking about ThinPrep, CT/GC, Trichomonas, HPV and that whole portfolio, women's health testing is really starting to have traction within the marketplace. And that, indeed, is being replicated internationally. We've had a couple of very big closes within the United Kingdom over the past 6 months, really, that again, have been portfolio of women's health products that we're offering. So in that regard, the revenue synergies, I think, we are comfortable with. And likewise and then again, with that physician sales force component has been tremendously important for us in terms of generating awareness of Aptima HPV, generating awareness of nucleic acid testing for Trichomonas right now. I think that has made a big, big contribution to us. I think what has happened, though, is some of the AUP pressures that we've seen again from the competitive activity within the market right now for our competitors trying to hold onto business or compete for business has certainly driven down some of the AUPs that we've been seeing. And then also, we had a little bit of a slow start to FY '13 as well, which did not contribute.
