Welcome to the third quarter 2022 analyst presentation for Bumrungrad Hospital Public Company Limited. We had another excellent quarter in Q3, and the main themes remain the same as what we talked about in Q2. The momentum has been sustained significantly due to ongoing strength in our international markets, for which we will delve more deeply into at a later stage in this presentation. Also we had rather solid Thai and expat revenue, especially when you consider in 2019 or pre-COVID levels, where we saw flattish growth in year-on-year terms during that period. There was a bit of concern as to how we were able to sustain growth in the Thai and expat market when we were continuing to reduce our discounting and promotions in line with our purification of margins going forward. When we look at also forward indicators that we talked about in the previous quarter, you will see that once again, volumes remain very bullish in forward terms because we started to see continued momentum in inquiries and appointment requests across all of our channels, voice, chat, and email. That, as a forward indicator, is rather strong in our expectation into Q4. I mentioned earlier about discount reduction being something that we've been embarking on since the beginning of this year. We do continue to expect the discount rate to fall, as well as economies of scale as we continue to ramp up volumes within the hospital itself. We will talk a little bit more about how that played out in the quarter. Moreover, we're thrilled to expect that bed availability will increase in Q4. With the renovation completion of the seventh floor wards in the hospital, we will be able to open new beds and therefore welcome additional patients as well. This should be a positive for us going forward into Q1 of next year. You can see on the graph, we continue to break through the pre-COVID levels quite solidly across the board, not only on revenue terms, and also in net profit terms. You might expect that, oh, there was a dip in Q2 versus Q3. That was mainly due to the one-off charge we booked in Q2 of 2019, and that created a low base effect with which to compare to. Factor that out, and the graph becomes a lot smoother and a lot more solid in terms of the upward trend trajectory. This is a new graph that I wanted to show you. We looked at the third quarter's profitability, and we were quite impressed with the margins that we were able to achieve. 26% in Q3 is nothing to laugh at. When I look at it among the competitive environment here in Thailand, i.e. the SET Health or the healthcare listed providers, we compare very favorably not only in margin terms, but also growth terms for Q3. On the right-hand side in the box highlighted there is where you want to be. High growth in operating revenue terms, but also high profit margins. You can see there we exceeded strongly all other peers that we compare ourselves to. This is data as of the eleventh of November, where we had 12 companies in the comparison. It's quite clear that we've had an excellent third quarter as a result compared to many of our peers. On to discount rate development that I talked about earlier, that continues to fall. It's at 12.4% as of the third quarter of 2022, and we continue to expect that to reduce going into the Q4 and furthermore in next year as well. That would continue to help benefit our margins as we continue to purify into areas where we want to focus on and remove unnecessary discounting where we can in order to unlock additional incremental revenue. I'm gonna talk a little bit about what I think is interesting for you to take into account when you look at how our margins have been so strong. One very important part of the cost structure in the hospital is the supply costs, and I'm comparing with you now the supply costs to operating revenue ratio. On the graph there, you can see that in 2020, the contribution to the cost structure was around 15.6%. That increased in 2021 to 16.2%. It was somewhat expected because we saw a reduction in revenue as a result of the continued closure of the country and the heightened COVID situation during that period. You can see from the beginning of this year going forward, so the Q1 to Q2 to Q3, that has come down significantly, and that has helped to uplift our margins to what we see now at around 26% as of Q3. That compares very favorably with what we saw at pre-COVID levels as well, and we do expect that continued cost management programs that we have in place will drive further improvements in this area. In addition to that, economies of scale for sure will help support this as we get more volumes into the hospital. There was some fear that the inflationary impact as a result of high oil prices, energy prices, and so forth, would impact negatively margins. That did not turn out to be the case in Q2 and Q3 as you can see. We continued to benefit significantly as a result of our prudent management of costs. Another major element is on salaries, wages, and benefits, SW&B, and that development also mirrored what we see on supply costs. We had a rigid program in place in managing manpower, and we had continued to work on developing additional operational efficiencies during the COVID years and going forward as well. That has borne a lot of fruit to us, as you can see in the graph there. In 2020, the SW&B costs as a percentage of operating revenue was at around 23%. That fell in 2021 to 22.8%, mainly from attrition as we did a hiring freeze. We did not hire any additional staff, but there was turnover during that period. As volumes ramped up in the beginning of the year, we maintained our headcount quite effectively as well as our OT costs, and that has helped to reduce those costs as a percentage of operating revenue significantly down to 15%. If you look at it on historical terms, it looks very, very favorable even when you compare with pre-COVID levels. Finally, I'd like to update you, which has long been anticipated, and we typically do this in the third quarter of any fiscal year, and that is the campus master plan. I also now include the construction, CapEx of the hospital into this amount, and that mainly relates to the renovation of inpatient rooms that I talked about earlier that we completed on the seventh floor of the hospital. Currently, you can see there on a five-year projection, we're looking to spend approximately THB 13.9 billion. The major part of that continues to be the Petchaburi Hospital, THB 9.25 billion in 2027, so very long dated. It's been pushed back another further year because we believe that there is additional capacity coming online, and I'll talk about that a little bit right now. Under new construction, you can see in Soi One, Petchaburi, in Soi One, we have the phase one construction of the parking building, that is due to be completed within this year. We. If any of you come to the hospital, you will usually find that parking space is very scarce, and it's difficult to find parking, and we're trying to ameliorate that situation by adding additional parking facilities. That is soon to come online and sure to help in that respect. On the BH Academy building, which is going to be office space for back office and management staff, that is also going to be completed very, very soon. We are, in fact, in the process of moving staff to that building in the next couple of weeks, and that is expected then to free up space, particularly at Building C or BI Tower, to move in additional clinics, additional revenue-generating capacity in that building. BH Annex, which is a building located adjacent to the hospital, is a new development that we're expecting to construct within next year, and that will also have an access bridge connecting directly from the hospital to this annex. There will be additional clinics being built there, in areas where we have noticed significant bottlenecks and significant traffic, and we have to look ahead at how we manage that in a way that benefits not only the patient, but also drives value to the hospital as well. On building A, not much change. We've done a lot of upgrades to MEP, et cetera, but what we plan to do is have a connecting bridge from the hospital to building A in order to facilitate greater access between the two buildings. In building B, a lot of construction is being done, particularly in certain specialties or clinics. We're looking at either expanding or renovating the hyperbaric clinic, the colorectal clinic, radiology, and also digestive diseases, physiotherapy, and the cath lab that will support our Heart Institute as well. The renovation of inpatient rooms will continue over the next 5 years, although we think the ongoing process will delay somewhat due to the high demand that we see, and that should help balance out the room availability for the benefit of the hospital going forward as we continue to welcome inpatients. On building C side, these changes remain the same as of last year. We're looking at moving out in certain levels, level 8, level 10, level 11, offices, and making changes to the clinics in order to support expansion on the outpatient side as well. You can see there, construction is mainly heavily skewed towards the next couple of years, and then that starts to pare down towards 2025 onwards with the exclusion of Petchaburi Hospital. I'd like to hand over the rest of the presentation to Neil Sorrentino, our Chief Global Strategist, who will elaborate further about developments in the various markets. Thank you. Welcome to Q3 analyst presentation for Bumrungrad Hospital Public Company Limited. As Daniel has delivered to you in his part of the presentation, the quarter was something remarkable for us. I thought about, as an operator of this business along with the team, you know, really what to say about the quarter. We'll get into a lot of the detail, but I've almost come to the conclusion that saying less is more when you have these kind of numbers for the quarter. Our crystal ball was completely broken in Q2 when I gave guidance for Q3. We had high expectations, and we were optimistic about Q3, but what happened in Q3 was far beyond our expectations. However, I will say that we have spent the better part of 24 months priming the pump internationally across all of our markets. We never lost focus. We never lost attention to our 60 referral offices around the world. We never lost focus to all of our Middle Eastern sponsors and clients. We stayed very, very close to all of the embassies that we have close relationships with. We did our homework in watching the business while we were going through this painful period called COVID. Let me get into some of the other aspects a little bit differently, but similarly to what Daniel talked about earlier, but give it a bit of a different forward look to it. When you look at Q3 at a high level, there were three pieces of business that drove the performance. Apart from the cost control, which has been good for the last two years, and it had to be good during COVID because we didn't have the revenue drive that we now have, which makes things more forgiving. The three considerable aspects of our business for Q3 were obviously the Middle Eastern business. Let me start at the top. Our revenue quarter over quarter grew almost 16%, 15.7%. What was most dramatic about quarter was our Middle Eastern business. Our Middle Eastern business grew 70+%. Our international business grew thirty, 33%, and the overall impact on total revenue was 15.7. When you step down the pieces of that business, you need to look deeper as to really who we are, what it has to do with, and I cover this at times in some other analyst presentations. It has to do with revenue intensity. We drive a great deal of bottom-line revenue, and if we manage the cost properly, we drive profitability as a result of the balancing act between revenue intensity, length of stay, and conversion of patients in and out of our workflow. I'm going to talk about each of the pieces of the business that drove Q3 in just a moment, but at a high level, that's what made the quarter. If I look at the international business contribution, I've given you the percentages, but that's the story for the quarter, international business contribution. I will talk about Thai business. I'll talk about expat business. They are always contributory. They are always important to Bumrungrad, but we are an international healthcare provider of services. We are the industry leaders in international medical tourism, and there was nothing more pronounced in that kind of thing and proving that than in Q3. I'm gonna slip down now to 2023 budget assumptions for you, because we get asked a lot about optimistic guidance for the upcoming quarters. I'll talk about Q4 guidance in just a moment, but let me touch on 2023 budget assumptions, and you are most welcome to ask questions during our live stream Q&A next week, with respect to the 2023 budget assumptions. For next year, 2023, we see the optimism continuing. Our business optimism now seems to be wide open with a number of different business channels that we haven't pursued before. We have attracted some very strong and outstanding leadership talent experienced in other international markets, which we'll be introducing you to as time goes on here. We've identified a number of markets we're not in now and some markets that we're in in a small way that we expect to get in in a big way. What does that translate to in terms of budget assumptions for 2023? On price, given wage inflation, given inflation overall, which could be pushing very, very low double digits in Thailand, we expect on price a 6.6% increase. On volume, we're taking a fairly aggressive point of view on volume, budgeting 7.8% increase on volume year-over-year at the medical center. Even more importantly, we're budgeting 2.9%, call it 3%, on revenue intensity. We expect to drive even higher revenue intensity. When we get to the presentation by my CEO, Artirat Charukitpipat, she's gonna talk about the existing as well as the new centers of excellence that will be driving additional business and revenue into the hospital. Those three components are going to be what we're going to strike towards insofar as 2023 performance goes. You can translate that any way you like in terms of your model, for those of you in the investor relations community doing modeling for the upcoming quarters. We've done our own budget assumptions, and of course, they're a budget, they're a forecast, but we need some kind of guidepost to go forward with. That's our plans for 2023. For Q4 guidance, this presentation, I'll work backwards instead of forwards as we've done in the past. Crystal ball is still broke. The optimism continues for Q4 2022 guidance. 15.7% was the top line revenue growth in Q3. We would not be surprised if it didn't make that number, but it's difficult to know. Usually, the last two weeks of December are slower times because the holiday period, many people practice Christmas festivities, New Year's, et cetera. We expect a bit of a slowdown at the end of the year, but to date, we're in Q4 now, and the performance continues strong like it was in Q3. Let's get in a little bit to the numbers themselves and give you some clarity beyond what we've talked about. I've shown the format, sort of the data modeling presentation of this slide in the last couple of quarters, but it is very revealing a slide because it shows you, the investor community and those interested in the company, what has been happening since 1Q 2021. I'm not going to go through the numbers for you, but if you look at just Q2 and Q3 alone, the variation on those grew from THB 4-almost THB 5 billion to THB 5.40 billion. On EBITDA, the EBITDA grew from THB 1.7 billion to THB 2.09 billion, up 36.4% on margin. If you look at the EBITDA margin, it's gone from 28.2 in 1Q to 34.4 in Q3, 36.4. Along the net profitability line, you see the same strong trend line from THB 1.1 to THB 1.5 billion, 26.2% margin. What's even more interesting about this, which I'll show you later, is that I had a look going back to the top quarter in 2019. This is pre-COVID, everyone. In the top quarter for us in 2019, I will show you these numbers later, but with respect to this slide, we exceeded all of those metrics for our top quarter in 2019. Principally again driven by strong revenue intensity. Next slide. Let's look at the markets. The most indicative aspect of this slide is what you see in the last column, the Q3 2022 percentage contribution. Take a look at the brown numbers going back to Q1 2021, at 25% for international, went from 25% to 56%, more than double. It goes with the decline in reverse, the decline in expat, and the decline in international. When you add up what we call international business, that equates to expat and Middle Eastern. You add 56 + 11, pushing 67% of our revenue is now coming from international business, meaning expat, meaning international combined. Our Thai business is down to normal numbers, a third of our revenue. If you go back in history, you'll see that at our peak performance, we were 2/3, 1/3. We're now actually back a little better than that number, 'cause the higher the international percentage to the total, the higher the revenue intensity, the higher the profitability is, we're managing our costs effectively. That's what you really saw in Q3 in a very dramatic way. Next slide. I mentioned earlier that the Q over Q change was almost 16% on revenue. Pretty strong numbers when you consider the baseline revenue for Q2 over Q1. It was double digits, and now this is double digits again. If you look at 3Q 2021, the comparative is not so, or 3Q 2022 year-over-year, because you're not really looking at apples to apples business basis for business basis. Next slide. For Thai business, it was almost a push, call it a little short of 1%, well 0.1%. That's a little bit deceiving, because while the Thai business was flat, you look deeper, the complexity of the patients, Thai patients we were taking care of in the quarter was quite high, and that drove a lot of revenue intensity. If you compare our business base quarter-over-quarter, the revenue contribution quarter-to-quarter was much different in Q3 for Thai business than it was in Q2. While this says, "Oh, well, the volume is flat," it's not as it relates to revenue contribution. Next slide. On the expat business, it was predictably down 5.8%, 6%, quite predictably. Look at the lower part of that slide, if you will, and you will see 2021 Q3. You see the dip. The dip is traditionally low in Q3 for us, and why is that? The dip is low because expat nationals, classically, their employment contract or their consultancy contract expires at the end of June. Either they get renewed or if there's a new wave of expat nationals coming into Thailand working here for international companies. There's always this lag in Q3 which drives down the business in Q3 for expats. The revenue intensity for those patients we took care of for expats was on average about the same as Q2. We won't talk about Q1 because it's not relevant. Next slide. All international, as I said earlier, in total was up 33% over Q2, again, driven by Middle Eastern business. I've talked about that already as well as Daniel has discussed it, so I won't go into that level of detail. Look at the bottom part of the slide. You'll see the rise variation over the quarters, what has happened over the quarters in the all international business. Very strong performance. Next slide. This slide here for me as an operator was very impressive. When you look at all of these international countries that drove business into BH in Q3, there's only one that didn't perform versus Q2, and there's a very good reason for that. That happens to be Mongolia. They have the equivalent of Songkran there in Mongolia. It's a big national holiday called Naadam, and all companies shut down. In addition to the Naadam holiday, which is a full 12 days, we also took advantage of closing an IPD ward to renovate it. The variation between the quarters is explainable by that amount. Look at all of the other countries in terms of the growth. I have typically gone through the base revenue changes. I won't take the time to do that now. I'll do that during our Q&A live stream next week to give you a magnitude of the number. Just quickly, Kuwait, Qatar, Myanmar, not only were the percentages, in some cases, huge, Qatar and Kuwait, but even with Myanmar only growing 1.7%, it was the number one or number two large volume country contributor for Q3 for us. The others are doing nicely too. China is not so much traveling Chinese nationals. It's more Chinese expats living in the country. There was a few Chinese nationals coming from China, but very, very few. This is mostly Chinese expats when you look at item number 10. Same for the United States. Three-quarters of that were expats living, they're part-time or retired here in Thailand. The UAE grew very, very nicely. It's been a big success story for us. We work very, very hard in regrouping that market for ourselves and doing many things in country that has brought that volume up by 300% year-over-year. Bangladesh, Cambodia, very strong markets for us in Indochina. Next slide. This slide needs no comment whatsoever except to say it grew 7%. Tremendous pent-up demand in the Middle East for patients wanting to come both to Thailand and wanting to come for very complex care at Bumrungrad. Throughout the quarter, we had more demand than we had beds. Throughout the quarter, we did struggle with staffing, trying to staff our beds to accommodate the number of patients who wanted to come to our hospital. Fortunately, we'll be adding more beds, we'll be adding more staffing, and we'll be expanding our capacity in Q1 of 2023. Because the demand is there. The pent-up demand continues. It's not abated. I'd like to remind you, if you look at the small print at the bottom of that slide, we talk about the four large Middle Eastern countries, but for each one of those other Middle Eastern countries, we are getting more and more patients. As an example, Saudi Arabia for the quarter was THB 48 million in revenue. That was 25% of that or less a year ago. Yemen has grown nicely. Iran has grown nicely. Bahrain has grown nicely. This is people wanting to travel, part of it, people wanting to come to Thailand. All of these markets know this brand very, very, very well. You can see how they frequented the brand in Q3. Next slide. Indochina was again a strong market led by Myanmar, up 14%. Same dynamic, same financial dynamic. The dynamics of this business is almost as strong on a revenue intensity and margin contributional basis as the Middle East, but none is stronger than the Middle East for us. Next slide. We now go to the EBITDA and the net profit. Oraphan Buamuang, our hospital CFO, will be covering this in some deep detail. Suffice it to say that over the quarter went up 23% for the quarter. If you look at the year-over-year numbers, it's hard to believe that it grew that much year over year. What's even more indicative of our ability to drive earnings is our ability to manage costs. Managing costs in the kind of environment we were in, and now this huge upswing in volume and managing our cost relative to that volume, and the drive intensity of that volume is not an easy thing to do when you have those wide swings, 'cause this is not a traditional med surg community hospital. We're doing some things here that aren't even being done in the United States. Next slide. The EBITDA, I put this together for you a little bit differently than the presentations in the past, 'cause I wanted to show you where we were Q3 2021, which you would expect given COVID, where we're producing EBITDA of THB 654 million, but look at Q3 in 2022, it's over THB 2 billion. Then if I take you back to our best quarter, pre-COVID, Q3 2019, the number was THB 1.574 billion against THB 2.090 billion. A huge jump in performance, apples to apples, pre-COVID, post-COVID. EBITDA margin at its best was 33.1% in Q3 2019, jumping well above that in 2023, Q3 to 36.4%, and even a 2% leap from Q2 to Q3 2023. You wonder where the limit is here. Everything has a limit. Nothing is infinite. But we expect further growth as long as we continue to put high revenue intensity volume at the top of this funnel. We'll have capacity to do that in 2023. Next slide. In a different way, presenting the EBITDA margin for you to see in a very, very clear way, more than double the EBITDA margin from 1Q 2021 to Q3 2022, from 15.3% to 36.4%. I'm not sure in the history of Bumrungrad, I'm not sure if that number, 36.4%, is not the high watermark for our company or not. In fact, I'll research that for you when we have our live stream presentation next week. If it's not, it's terribly close to the number. Next slide. Profitability was up almost 30%, 28.8% quarter-over-quarter for all of the reasons I just have been mentioning to you and speaking to you about. Next slide. Again, the similar presentation, different than what I've shown you in the past, showing you a high-water mark Q3 2019, 22.2% was our net profit margin there. This quarter, Q3 2022's, 26.4%. On the turnover number up at the top to drive four additional percent to the bottom, on that proportional turnover number is really a very strong performance by this company. Next slide. Profit margin in the same way as I've shown it earlier but in a different format, so you can see, the weakness during COVID at 3.4%, profit margin in 1Q 2021 back up to. That may be a historical high too. I'll have to have a look at that. 26.2%. We didn't do this through raising prices. Did this through revenue intensity and good cost control. Next slide. Our other prized asset among 18 different companies that are part of BH PCL was VitalLife. VitalLife now has two units operating, one on the campus and one at RAKxa. They're both doing very well. If you look at the VitalLife financials was up almost 15% on revenue. You can see the period-over-period performance growth at VitalLife. This scientific wellness center has just been on fire in 2022. Look at the EBITDA up 16.5%, up 258% against Q3 2021 a year ago. Next slide. Look at the VitalLife fundamentals for the last three quarters and as against 3Q 2019 where it was THB 178 million, pushing almost a quarter of a billion on total revenue. On EBITDA, THB 97 million against THB 60 million in Q3 2019. A nice jump from Q2 of 16.5% from THB 83 million to THB 97 million. It's used to grow and diversify into a longevity formula that patients are finding very informed about and very, very interested in because post-pandemic, people are very, very concerned about wellness and lifespan and health span, and it's attracting a great deal of attention both domestically and internationally. This is a business that used to be 0.5% of our contribution, is now pushing 5% of our contribution to the bottom. We see this particular business growing dramatically over the next three-year period in a number of different ways, physical expansion, virtual expansion, and digital expansion. It has its own website now, and the digital component and the virtual component of this business are future growth opportunities for VitalLife and BH. You've seen them all. You understand what happened in the quarter. We're quite open and available to answer your questions, next week during the stream. With that, thank you very much for your attention in joining us, and we'll see you next week. Good morning, everyone. I'm Oraphan Buamuang, Chief Financial Officer. I'm pleased to report to you all the financial highlight and financial performance for third quarter 2022. Move to see the financial highlight. As the result of Thailand reopening since first of November 2021, both Thai and non-Thai revenue grow substantially year over year. The higher contribution of international medical tourism, particularly from Indochina and Middle East, has a significant positive impact to revenue intensity. In third quarter this year, financial performance were improved when compared to second quarter this year and third quarter 2021, and also above than third quarter 2019, which was pre-COVID situation already, as shown in the first table. In terms of the profit margin in this quarter, EBITDA margin and net profit margin were 36.4% and 26.2% respectively, which are the highest record. I will walk you through in more detail in the next slide. Financial performance. The consolidated revenue in third quarter this year was THB 5,740 million, increased from third quarter last year by 92.1% and also above than third quarter 2019 by 20.6%. Year-over-year increase in revenue mainly came from both of non-Thai and Thai patients by 213% and 10% respectively. When compared to pre-COVID situation in third quarter 2022, revenue from hospital operation increased by 20.6% from third quarter 2019. This was mostly due to an increase in revenue from non-Thai and Thai patient by 21% and 18.1% respectively. Moving to the 9-month 2022, total revenue was THB 14,847 million, also increased from same period last year by 71% and also above than year 2019 by 7.9%, mostly due to an increase in revenue from Thai patient by 23.6%, while revenue from non-Thai patient recovered to nearly 100% of year 2019 already. In terms of revenue contribution by nationality, in third quarter this year, due to an increase in revenue from non-Thai patient and Thai patient by 213% and 10% respectively. As a result, the revenue contribution from Thai patient was 33%, whereas revenue from non-Thai patient was 67% for third quarter this year, which was almost the same portion in third quarter 2019. For nine months 2022, due to an increase in revenue from Thai patient by 23.6%, while revenue from non-Thai patient recover to nearly 100% of year 2019 level. As the result, the revenue contribution from Thai patient was 38%, whereas revenue from non-Thai patient was 62% for nine months this year, compared with 33% and 67% respectively for nine months 2019. Move to see revenue contribution by service. In third quarter this year, revenue contribution from outpatient service increased to 52% from forty-seven percent in third quarter last year due to OPD revenue increased by 107%, while IPD revenue increased by 65%. In nine months 2022, revenue contribution from outpatient service increased to 52% from 47% in nine months last year as well, due to OPD revenue increased by 84%, while IPD revenue increased by 47%. When compared to portion in year 2019, the proportion between OPD and IPD were coming back to pre-COVID situation. For revenue contribution by payer type, self-pay contribution increased from 65% to 70% in nine months this year, mostly due to revenue from self-pay patient increased by 86%. The increase came from an increase in international segment. Insurance contribution in 9 months this year declined to 16% from 21% in 9 months last year due to revenue from insurance in 9 months 2022 increased year-over-year by 31%, which lower than self-pay revenue increased by 86%. The government third party contribution in 9 months this year slightly increased to 13% from 12% in 9 months last year due to Medi-gap patient increase. In terms of the EBITDA, as the result of increased revenue and continued cost management program, EBITDA in third quarter 2022 was THB 2,090 million, improved from same period last year by 220% and improved from third quarter 2019 by 33%. EBITDA in 9 months 2022 was THB 4,966 million, improved from the same period last year by 203% and improved from 9 months 2019 by 14% with EBITDA margin 33.4%. For EBITDA margin in third quarter this year was 36.4%, which was the highest record. EBITDA margin in 9 months 2022 was 33.4%, which was above than third quarter 2021 and third quarter 2019 at 18.9% and 31.7% respectively. For net profit of this quarter was THB 1,501 million, which improved by 407% and 42% from third quarter 2021 and third quarter 2019 respectively.

Here is our CSR activity during this quarter. We supported Lumphini Police Station by providing first aid and standard medical supplies. Apart from supporting the government policy for the free vaccination to community for around 67,000 doses at Bumrungrad Building A on the 10th floor, I think everyone remember that we provide flawless experience to the public. We also donated Moderna vaccine for more than 55,000 doses to almost 30 public sectors, which is include government hospitals. As you can see on the right-hand side, this is the example of donation 10,000 vaccines to inmates and staff at Bang Kwang Central Prison. As you know that Bumrungrad competent in treating complex, critical, and high-intensity cases by using cutting-edge technology. We stay focused on our 5 centers of excellence, which are Heart Institute, Horizon Cancer Center, Neuroscience Center, Digestive Disease (GI) Center, and lastly, Comprehensive Eye Center. We just launched Cornea Transplant Center in our Comprehensive Eye Center. These centers provide full subspecialty of expertise, evidence-based practice, research and development, which are well accepted by patients worldwide. That's all for me.
