Thank you, Katherine. This is Arthur. I will take these two questions. First of all, just quarter-to-date, I just want to share some color. Definitely, I think the market fluctuations quarter-to-date have some negative impacts on our average client assets. So far in the wealth play, our average client assets will be down along in the range of 10% to 20%, mainly attributed to the markets and market loss, but we are very confident because even quarter-to-date almost every day we still see meaningful net asset inflows in terms of the wealth accumulations in Futu platforms. Therefore, as you think, if the market back to normal, since marketing - market loss or gain will be come to the average numbers. And in terms of the clients trading velocity, we do expect trading velocity have some rebound in the - in July and August, given the market - especially high tax costs have meaningful setbacks, we do see some from more transitions, from the retail investors and unlike - meaning, unlike the situation in second quarter, many investors set on the sidelines, we do see some participations in the third quarter. So it's based on the current run rate. I would expect in terms of top lines, we may see some sequential Q-on-Q increase in the third quarter compared with the second quarter. In terms of the client acquisition cost, I think on an absolute amount levels, this marketing campaign spending will be roughly in line with what we gave in the second quarter, but definitely the client acquisition speed will slow down due to the market conditions. So this will affect the normal denominator numbers and then we will let our CAC numbers have certain increase in the first quarter compared with the second quarter. For your second questions, I think number one, our BI structure is slightly different for many - compared with many Chinese ADR companies, because most of our revenue are now derived from the offshore, essentially we do not generate any revenues from our BI structures. So even there will be some new regulations on the BI structure, I do not expect that we will have some meaningful impact operational wise or financial wise to our business. And definitely we have noted some recent trends in the capital markets and we are actively conducting quality research and valuation gets sorted out. We will make a very comprehensive assessment to ensure that decision to maximize our shareholders' - that the long-term interest is met. Thank you.
