Well, I guess, let me try to address it in a broader context, JoAnne. What you're really asking, if I could put it in a simple -- in a more direct context, is, are we seeing a lot of competition in FBAR filters? I would preface that by saying, we always have competition from SAW filter manufacturers, from SAW filters. SAW filters may not perform as well as FBAR, but in many, many bands, they perform adequately. And given the price differential between FBAR and SAW filters, many phone makers prefer to use SAW filter cost point of view. Having said that, the increasing number of bands, some of them in China and in Europe and even North America, where those bands require the use of FBAR filters or duplexes, I should say, or filters, in order to get -- receive signals in an adequate -- in a satisfactory manner to meet those specs. And in those areas, we have, as I mentioned in my remarks, seen some emerging players showing up and offering those kind of -- similar kind of FBAR filters, perhaps. That's true. Having said that, we are still, by far, larger. We are still also, in terms of technology and design performance, by far, well ahead of all those. But having said that, we are not taking that -- we are not -- we're obviously taking those competitions seriously, and we will continue to do that. And the way we do that and stay ahead of the game is we continue to design filters faster and better even in terms of next-generation filters for the same band, much better than our competition. And really, it's all about staying ahead in the marketplace. We do see some of that. But as I pointed out earlier regarding an earlier question related to the same thing, we're still very far ahead of the curve, and we intend to remain that way. And we certainly intend to differentiate ourselves either on a discrete basis by having very high-performing filters for some of the phones or bands in China that requires those filters in TD-LTE and Wi-Fi or that we couple it with, as you pointed out, power amplifiers, very good performing amplifiers, to create what we call front-end modules or pads, which takes away -- which removes a lot of competition from players who either do not have FBAR filters or do not have power amplifiers [indiscernible], okay? And that's -- there are not many players out there who have both FBAR filters and power amplifiers, and by that, I mean have those capability in a very, very advanced and technologically progressive manner. There are very few out there.
