Thank you, Michael. I would like to go through the first quarter 2023 investor conference presentation material, which can be downloaded or view in real time from our website. Starting on Page 4, the first quarter of 2023. Consolidated revenue was TWD 54.2 billion, with gross margin at 35.5%. The net income attributed to the stockholder of the parent was TWD 16.2 billion, and earnings per ordinary shares were 1.31. Wafer shipments in this quarter come at 126,000 equivalent wafers which was a decline of 17.5% quarter-over-quarter, which also fall in the better end of our previous guidance of 17% to 19% decline for the first quarter. Utilization in first quarter is as we guided around 70%. For Page 5, the sequential comparison, revenue declined 20.1% and to TWD 54.2 billion. Other than the 17.5% wafer shipment decline, there's also a negative impact of 3% plus impact from the ForEx due to NT dollar appreciation. Gross margin rate was 35.5%, which is a 34% decline to TWD 19.2 billion. Operating expenses was lower than the level of Q4 last year at TWD 5.78 billion. This is a typical first quarter seasonal factor. So we do expect this number to increase in the second quarter of 2023. Nonoperating income total reached TWD 4.64 billion, which is quite a significant improvement from the fourth quarter of last year. mainly due to the recovery in the stock market for our portfolio. And net income is TWD 15.38 billion and net income attributable to the shareholders of the parent is with a net income margin of 29.9%. EPS is 1.31 for the first quarter of 2023. On a year-over-year comparison on Page 6, revenue declined 14.5% and net income declined by 18.3%. So the first quarter of 2022 was 1.61 in EPS, and this quarter is as mentioned, 1.31 for the first quarter of 2023. So on Page 7, cash remained nearly unchanged around TWD 171 billion. Due to the continuous CapEx, we can -- we have seen our total assets increased to TWD 549.6 billion. On Page 8, our blended ASP for wafer equivalent has inched up in Q1 '23. For Page 9, our geographic breakdown. For revenue, Asia showed a bigger decline from 54% in the previous quarter to 50% in the first quarter and every other region has increased sequentially. And for Page 10, IDM has shown a stronger growth in the first quarter. Now the percentage of revenue reached 23% when tablets represent about 77% of our total revenue. In terms of segment breakdown on Page 11, this quite meaningful mainly driven by when computer and consumer and also communication are all showing some decline in percentage of revenue. On Page 12, our revenue for 14-nanometer technology and below represent around 41% of our total revenue, although 28 and 22 nanometers still on 26%, so about 2% decline from 17% to 15%. Q1 2023 was the lowest point in terms of available capacity, mainly due to the annual maintenance schedule for selected sites. Quarter 2, you will go back to the normal. And also on top of that, will be P6, our Tainan fab expansion will start to kick in, and we can see the capacity increase for fab 12A. So overall, we will see a low single-digit increase in our available capacity from quarter 2 2023. On Page 14, our annual budget for CapEx remain unchanged. -- around $3 billion. And it's going to be a little bit front-end loaded in the first half and 90% will be related to 12-inch expansion and 10% is more related to 8-inch capacity. So the above is a summary of UMC results for first quarter of 2023. More details are available in the report, which has been posted on our website. I will now turn the call over to President of UMC, Mr. Jason Wang.
