Thanks, Steve. Charlie. So I'll answer the first 2 parts of your question. So in regard to tax, yes, we previously have stated that we expect the tax rate, not indefinitely, but over the medium term, to be in the high teens. Clearly, that's a function of the factors that I mentioned before, which is earnings mix. And we did see a little bit of up-skew towards higher product earnings in the higher tax rate areas, so that's impacted it slightly. The Diabetes business going away actually hurt the rate a little bit as well. But on average, looking at all the different factors that I mentioned, including our tax planning strategies, yes, I still feel in the medium term that that's a good barometer to use. As it relates to trends, vis-à-vis, how we are looking through the 3 quarters and then in the fourth quarter, a few things to recognize. The bullets of the BARACLUDE impact is going to happen in the fourth quarter, where also as I mentioned earlier, the Diabetes royalties, the way they're structured and the -- so we get a pretty good royalty on the first $500 million. We really don't get much as we get to the balance of this year. We also have the transaction services agreement with AstraZeneca, whereby that pretty much drops off in the fourth quarter. And then we do have commercial investments that we are continuing to make in the business around Yervoy as we begin the preparation for the launch of Opdivo, Eliquis DVT. And also as you look at the R&D spend through the 3 quarters and what we see in the back half of the year, we do see, particularly in regard to I-O, expanded patient enrollment continuation of new study starts, including several clinical collaborations exploring combination regimens. And then we do have some costs related to comparator-arm studies. So by and large, we do see an increase in our overall expenses from a trend-wise in the fourth quarter.
