I think as I mentioned already, you know, we are facing significant opportunities in the mobile space, and that's why we're deploying a lot of resources, whether it's talent or infrastructure or marketing efforts, to position ourselves. Obviously, you know, when investors look at the margin, it's a combination of the speed of revenue growth as well as investment. It does not necessarily coincide at the same time when you incur expenses, you generate that kind of revenue. Obviously as we invest, we want to make sure that we position ourselves well, and we will have revenue generation capabilities going forward. So this is, you know, where we are. If I look at the investment themes of the items that incur significant resource allocation, infrastructure, you know, we are building the cloud capacity and we want to really be the key player to host the content to help users, you know, to storage, to help really manage, you know, the huge database that has, you know, our core technical competency. There are fewer players in the country that can do that. And we're in the early stage to invest in infrastructure. And when you look at R&D talent, we have been growing, particularly R&D talent, very fast over the past few years. It's hard to imagine that we will continue that pace as fast as it used to be. So, over time I think, you know, as we look at the people-related matters, that hasn't been -- that has been the case for sales and we have slowed down hiring and sales and putting our emphasis on R&D. So we have a very clear focus on where we are going and what we need to do and how to allocate resources towards that. And sales and marketing is a very special item for us at this juncture because we have products that we need to aggressively push. And it is, you know, I think that we are at an advantageous position because I think all the, you know, all the businesses that we have done very well over the years has built us the capability to aggressively promote our products and position ourselves for the future. Obviously we are doing this with the objective to generate huge success and revenue growth potential. And therefore return to the shareholders. So that's -- this is basically, you know, the cycle we're running the business. There is -- the industry itself continues to evolve. It's hard to say, you know, this year, next year, you know, when it will be end. And I think, you know, it is a continuing theme. And I think when the time comes that we feel this is, you know, we're well-positioned, I think all parties will be happy to see that.
