First of all, Philip, we have decided to use heterojunction, HJT, technology for our U.S. domestic solar cell factory a few years ago. Before the legal challenge from First Solar. So we made a decision independently, because we believe we are a master of the HJT technology. And this technology has some very distinguished advantages. First of all, HJT has higher theoretical efficiency limit than the TOPCon solar cell. And second, although both TOPCon and HJT are N-type for the application on earth, it's N-type. For the operation in the space, some scholars believe P-type HJT has more advantage. But although the TOPCon and HJT are both N-type, HJT does have higher efficiency and also thinner wafers. It has the potential to go thin wafers, therefore, further reduce the cost. Also, there was another advantage of HJT technology which just appeared, become more significant recently, which is the low silver use. When we decided on the -- to use HJT for the U.S. factory, the silver cost was not that high like 2, 3 years ago, polysilicon cost is still #1, not like today, the silver cost all of a sudden become #1. But the HJT use the so-called low-temperature process, as you probably know, the processing temperature -- the highest processing temperature is around 200 degrees C rather than for N-type TOPCon, which have to go through some 800, 900 degrees C process. Because it's low temperature, we can potentially use less silver and more copper in the paste. Therefore, it will have very significant savings in terms of silver cost. Recently, I have called the R&D team in our company to focus on what I call the zero silver technology. And for zero silver, we can see that the HJT will go faster than the TOPCon technology. So because of those [ event ], also, HJT is more of -- is a more automated and equipment-dependent process than operators dependent. And its operator per watt capacity is much less than the TOPCon. So it will make -- reduce the initial operator training burden for us in U.S. That's why we do introduced HJT. And as I said in my remarks, we will see the first piece of HJT cells of our lines in Jeffersonville, Indiana by the end of this month. So next quarter, we will start the ramp-up process for the Phase 1. So I think that the result today, what happened today shows that we made the right decision on the technology selection, also showed our [ steps ] in the R&D and technology reserve in the company. Now turning to the -- on the legal patent side, I don't want to comment too much on the legal cases. But I do want to emphasize that USPTO pretty much rejected all the review request for patents. It's not specific to us, but it's rather a change of their practice. I don't think it affect or it will weaken our position in front of the court. We have -- we firmly believe that our technology is found. And also, we have not infringed any of other patents. Now in terms of 337, it's going to be approximately a 1-year process or more than 1 year. So it's a process in front of ITC. So we'll let the process go. But as I said, we are confident on our technology and our patent determination. And -- but meanwhile, we have -- also have flexibility as you see that we have the HJT technology going in U.S. already. And by the end of this year, we will be ramping up the Phase 2. So in Q1 next year, you will start to see 6 gigawatts, 6.3 gigawatts of nameplate capacity running in the United States. That will more or less cover a large part of our solar cell requirement of our Mesquite solar module factory. As I also said that our -- we increased our nameplate capacity of the solar module [indiscernible] factory in Mesquite, Texas to 10 gigawatt. So for the remaining 3 gigawatts, we will either use TOPCon to supplement or we might use PERC technology. So altogether, I'm confident that right now, what we are seeing right now is a transition process ongoing. But starting from second half of this year, overall, you will see the result of this transition. So I think we are the -- one of the most -- will be the most stable players in the global market, especially in the U.S. market.
