Thank you, Angela, and hello everyone. Welcome to our first quarter 2022 earnings call. As an integrated telecom service provider, we achieved strong performance in the first quarter in terms of mobile, fixed broadband and ICT businesses under our new corporate structure. Let's go on Slide 4 for an overview of our business. In the first quarter, the mobile market in Taiwan remained steady although the competitive landscape may change as our peers announce their major plans. We were pleased to see the market consolidation and I believe the in-market structure could lead to further competition in Taiwan. For Chunghwa with our most extensive networks for services, we are fully confident in maintaining our leading position in the market going forward. Our revenue and our subscriber market share, excluding IoT SIMs, continued to outperform peers in the first quarter by reaching 39.1% and 36%, respectively, currently in the digital status. Slide 5 presents our overall mobile business performance. Our mobile subscriber number, excluding IoT SIMs, increased by 0.7% year-over-year. With the successful upsell from existing subscribers, our mobile service revenue increased by 4.9% year-over-year and maintained its upward trend. In addition, 5G penetration developed steadily during the quarter, which helped to enhance the postpaid ARPU to achieve 3.2% year-over-year increase. Meanwhile, we observed an average 35% uplift in monthly fees attributable to customers who renewed contracts to adopt 5G services. Moving on to Slide 6 for an overview of our overall fixed broadband business. In the first quarter, we are pleased that we see both our fixed broadband subscriber number and high LAN subscriber number continuing to grow year-over-year reflecting our leading market share in Taiwan's fixed broadband market. Fixed broadband revenue in the first quarter continued to increase by 4.4% year-over-year due to the ongoing growth of higher speed service adoption driven by digital opportunities. The number of sign up for commercial speeds of 300 megabits per second or higher increased by 41% year-over-year owing to work from home lifestyle. Fixed broadband ARPU also continued the growth trend for the tenth consecutive quarter increasing by 3.5% year-over-year further enhancing our overall performance. Now let's move on to the performance of our customer-centric business groups. Slide 8 illustrates the revenue picture of our Consumer Business Group or CBG. CBG revenue in the fourth quarter increased by 2.2% year-over-year reflecting our success in satisfying customers' needs during the quarter. Mobile service revenue for the Consumer Group grew 4.9% year-over-year mainly due to the increase in postpaid subscriber numbers and 5G migration. Fixed-line service revenue maintained its upward trend during the quarter attributable to additional stay-at-home digital opportunities thus encouraged higher-speed service adoption. Sales revenue decreased year-over-year mainly due to the handset supply issue under COVID-19 and the demand at home and from consumers continued to drive up the group's other revenues say MoD and HiNet video to achieve a 5.2% year-over-year increase during the quarter. Looking ahead, to further expand opportunities in the consumer market, we will package and deliver more customer-centric services to increase market demand focused on media, sports, gaming and automotive or reality -- virtual reality applications. Slide 9 further demonstrates our highlights of Consumer Business Group. Including MOD, formal media and the Triple Play program that promotes fixed broadband, mobile and WiFi services. In January catering to work from home demand and state opportunities, we rolled out a Triple Play program to encourage consumers to enjoy seamless broadband connections by adopting our mobile and WiFi services together. This program at the same time sign up of Home WiFi device continued to grow by 29% year-over-year to sustain the popularity of our home centric applications. In terms of our IPTV and OTT businesses, we are glad to report that the total subscriber number of MOD and Harmonic video [grew] their monthly fee on yearly basis instead of onetime setup, increased to approximately 2.6 million during the quarter remaining the largest media platform in Taiwan. MOD revenue maintained its upward category as SVOD revenue grew by the fifth consecutive quarters driven by upscale and channel service continued to increase year-on-year. which was due to 90% sell-off of HiNet packaging among the tier pricing space. In addition, Harmonic media subscriber number boosted in the first quarter thanks to popular packages and international at [Indiscernible] during the quarter. We expect the growth trend to continue for this year as popular international sports events will be held one after another to attract subscribers such as Asian Games and FIFA World Cup held in the second half. Please turn to Slide 10 for our Enterprise Business Group performance. In the first quarter, Enterprise Business Group revenue increased 2.1% due to the year-over-year growth of mobile and fixed broadband revenues and enterprise customers increased communication usage in the new normal. In addition, Taiwanese overseas small and medium enterprise that shift their operations and their investments back home also brought in fixed broadband demand and related revenues. For Enterprise ICT business, we are glad to see the total gross margin and the profit increase year-over-year. In the first quarter, the revenue decreased year-over-year owing to certain [different]of project revenue recognition. However, we remain positive about the full year performance of our Enterprise ICT business. Slide 11 demonstrates our Enterprise Business highlights. We are glad to report growth momentum of our emerging enterprise applications. In the first quarter, 5G Enterprise private network revenue tripled its growth year-over-year confirming our strong progress ahead of our peers. On a year-over-year basis, mobile ICT revenue and the IDC revenue increased in the first quarter due to completion of large projects while cybersecurity revenue reached double-digit growth attributable to an increase in both project and recurring revenue. Our efforts to develop capabilities of big data analysis worked and achieved 9% revenue growth. For ICT project performance we work with subsidiaries, the Chunghwa System Integration and Chunghwa Security International, to successfully acquire the first Smart Harbor project in Taiwan to realize 5G unmanned vehicle inspection. We also acquired a large integrated Smart Health project, which translates our strong network and ICT capabilities into long-term recurring revenue. Going forward, we will continue to leverage company resources and technologies to further develop our enterprise business opportunities. Slide 12 demonstrates our International Business performance to duplicate our successful solutions and services to the overseas market. For decades, our International Business Group has continued to develop a localized approach in many overseas markets and serve global clients to deliver services in Taiwan, which is a unique advantage for Chunghwa among peers in Taiwan. In the first quarter, our International Business Group revenue increased 13.8% mainly from growing demand of our IDC, cloud and ICT services offering for global clients, including some global OTT service providers. Our strategy is to cater to the growing business opportunities and provide quotable service including fixed line, undersea cable, IDC and HiNet peering to sustain revenue growth. I would like to highlight our investment in international undersea cables in particular, primarily in the [Indiscernible] and airport consortiums, that enable us to capitalize on growing opportunities from international OTT service providers.
