Rod B. Hall - JPMorgan Securities LLC
Management
Okay, great. Thank you. And then for my follow-up, I wanted to ask you about the tax situation a little bit. Treasury obviously has made some rule changes, and I wonder maybe if, Luca, you could comment on what the impact to Apple from those is, if anything; and, Tim, maybe more broadly, how you guys see the tax situation for Apple looking forward? Thanks.
Luca Maestri - Chief Financial Officer & Senior Vice President: Yes. Rod, these are new regulations. We are in the process of assessing them. Frankly, from first read, we don't anticipate that they're going to have any material impact on our tax situation. Some of them relate to inversion transactions, so obviously that's not an issue for us. Some of them are around internal debt financing, which is not something that we use, so we don't expect any issue there. As you know, we are the largest U.S. taxpayer by a wide margin, and we already pay full U.S. tax on all the profits from the sales that we make in the United States. So we don't expect them to have any impact on us. On tax reform, maybe I can continue, and I'll let Tim provide more color, but we've been strong advocates for comprehensive corporate tax reform in this country. We continue to do that. We think a reform of the tax code would have significant benefits for the entire U.S. economy, and we remain optimistic that we're going to get to a point where we can see that tax reform enacted. At that point in time, of course, we would have much more flexibility around optimizing our capital structure and around providing more return of capital to our investors.
Timothy Donald Cook - Chief Executive Officer & Director: The only thing I would add, Rod, is I think there are a growing number of people in both parties that would like to see comprehensive reform, and so I'm optimistic that it will occur. It's just a matter of when. And that's difficult to say, but I think most people do recognize that it's in the U.S.'s interest to do this.
