Thank you, Angela, and hello, everyone. Welcome to our first quarter 2021 earnings call. Before providing an update on fourth quarter performance, I would like to begin by highlighting the ongoing success of our strategic transformation that began in 2019. Three years ago, we launched a customer-centric transformation plan focused on value creation to enhance our market position. Under this plan, we start to improve our competitive advantage by strengthening our core businesses, deploying emerging services, optimizing our cost structure and further enhancing fundamentals such as next-generation networks, IT infrastructure and human resource training. We concluded our 3-year plan at the end of 2021 with stable key achievements, including our are 3 years of consecutive growth in EBITDA margin, net income and the EPS. Mobile service revenue turned around since the second quarter of 2021,and the churn rate significantly decreased from 2019 to 2021. In addition, the compound annual growth rate of broadband revenue increased by 2%, increasing the enhancement of our core business. Because of emerging business, we are geared to see compound earning growth rate for both IDC revenue and the cloud revenue increased by 5%. Our ICT business gross profit increased to 70%. By 2021, our broadband network was 100% software definement work-ready and fiber-to-the-home coverage reached approximately 88%, demonstrating our enhanced core competence. The net promoter score, NPS, of our services also increased, which reflects the increase in customer satisfaction. Revenue and profit per head increased 6% and 15%, respectively, attributable to increased operational efficiency as a results of cost structure optimization. Along with the strategic transformation, on Slide 4, you can see we have an organizational transformation effective on January 1, 2022. We transformed our business groups under customer-centric structure. We expect our consumer business group to develop individual and home-centric business, such as mobile fixed broadband, WiFi, MOD and OTT services. We aimed to create value and better experiences for our customers. For our enterprise business related unit has been transformed into a single business group to streamline service delivery and create a synergy. In addition, the international business group has continued its outreach as we expand our business into overseas territories. Similarly, our technologically focused units have been transformed into 3 groups, forming a strong foundation to support and operation and provide solutions. Meanwhile, our headquarters will continue to maximize expansions of devising planning and resource allocation. In sum, we expect the new organization structure to bring more customer-centric and responsive as we aim to provide better value creation opportunities for both customers and stakeholders. Now please turn to Slide 6 for an overview of business from the fourth quarter of 2021. In the fourth quarter, the mobile market in Taiwan remained steady as operators focused on 5G migration and development. By the end of 2021, our 5G penetration rate reached approximately 20% as we expect the -- this rate to reach by the end of 2022. As we continue to lead in network quality by accelerating 5G deployment at better locations, we remained provident on 5G customer migration and reaching our target maintaining our leading position in 2022. In the fourth quarter, 5G migration continued to drive ARPU uplift. We observed an average of 49% uplift in monthly fees attributable to customers who renew the contracts to above 5G services, particularly from the contribution of iPhone 13-bundled subscribers. Our excellent home-based infrastructure was well received in the fourth quarter as well. The number home WiFi devices continue to soar by 167% year-over-year. Broadband subscriber number turned positive during the quarter, while revenue hit a record high in December. The subscriber migration to our broadband services of 300 megabits per second or higher increased by 45% year-over-year. Our broadband ARPU also continued to increase year-over-year, in line with our expectations. MOD ARPU also grew on a year-over-year basis as a result of successful upselling during the quarter. Looking ahead, we will strive to develop video services by providing more popular content and leveraging 5G to create immersive viewing experiences. We are pleased to announce our ICT business achieved its full year revenue and margin by the end of 2021. In particular, the ICT project margin for 2021 continued to grow, which is reflective of our over performance and demonstrating that our enterprise business is on track and expect to do well in the future. Now allow me to walk you through each of our business lines. Turning to Slide 7, you may find the updates on our mobile business. In the fourth quarter, we maintained our leading position in the mobile market. As both revenue and the subscriber market share, excluding IoT SIMs, increased to 38.9% and 36.1%, respectively. During the quarter, our mobile customer net adds and postpaid net adds both ranked highest among the big 3 majors as postpaid subscriber numbers increased year-over-year and the 5G migration enhanced the adoption of high-priced plans. Our mobile service revenue maintained its upward trend, resulting in a year-over-year increase of our postpaid ARPU. Looking ahead, we will guide our services with a key focus on our customers, rolling out popular bundled services for innovative 5G applications to further drive up 5G migration and mobile ARPU. Please turn to Slide 8 for an update on our broadband business in the fourth quarter. During the quarter, our subscriber net adds continued to increase year-over-year, and the broadband subscriber net adds turned positive year-over-year, which reflects the market's growing demand for fixed broadband. We were also pleased to see that our broadband ARPU increased by 3% year-over-year, attributable to our success in migrating subscribers to adopt higher-speed services. In addition, the number of subscribers that sign up for commercial speeds of 300 megabits per seconds or higher increased by 45% year-over-year. Looking ahead, we are confident that we will maintain the overall upward trend in our broadband business as we believe our digital transformation trend is most likely turning back. As our consumer business group prepares to develop small solutions, we expect to introduce more popular home-centric services in the future to enhance customer user experience. Slide 9 illustrates our MOD business performance. In the fourth quarter of 2021, MOD subscriber numbers decreased slightly, while our media subscriber number increased by 20% year-over-year. Despite this, MOD revenue maintained its growth trend and increased 2% year-over-year as a result of our pricing strategy. The SVOD package that rolled out in the fourth quarter of 2021, quickly accumulated a gross subscription number and the service volume strengthened SVOD revenue growth for 4 consecutive quarters. General revenues continue to increase year-over-year as 90% of subscribers opted for the highest-priced package among the T pricing schemes. As a result, MOD ARPU achieved a year-over-year increase in the fourth quarter. Moving forward, we will make investments in content development to further enhance our video service performance and different billing platforms to maintain our leading position as the largest video platform in Taiwan. Please turn to Slide 10 for an update on our ICT business. In the fourth quarter, both ICT project margin and the gross profit increased year-over-year as a result of our effort to take our -- to take on projects with high returns, which is positive to our overall bottom line. Excluding the large project impact from 2020, ICT revenue in the fourth quarter increased by 22% year-over-year, mainly due to revenue recognition from financial projects, and the cloud revenue increased 3% year-over-year. Revenues from cyber security decreased year-over-year due to delays in project revenue recognition. However, we remain positive that the aforementioned business will grow at a double-digit rate in 2020 -- in 2021 -- sorry, 2022. In 2021, we were glad to see the 5G private network reach $1 billion value as a result of our recent efforts, such as introducing the first 5G smart factory in Taiwan. In addition, we were proud to report some indicative ICT projects such as building the first response emergency signal control system in Taiwan. Big data analysis performs for large property service companies, as well as the network test field for 5G vendors. Looking ahead in 2022, we are pleased to see that the number of orders taken has exceeded our annual guidance mainly attributable to opportunities from the government, enterprises, retail stores and the tourism industry. Now I would like to turn the call over to our CFO, in Vincent Chen, who will review our financial results. Vincent, please go ahead.
