Good afternoon. This is Poong Young Yoon, CFO of SKT Telecom. Let me first discuss the consolidated earnings highlights for fiscal year 2020. Consolidated revenue for fiscal year 2020 recorded KRW 18,624.7 billion, up 5% year-on-year. A well-diversified ICT portfolio built around hyper connectivity enabled quick adaptation with a nonface-to-face business environment, thus resulting in sustained quarterly growth in all business divisions of MNO, media, security and commerce. As a result, we recorded yet another record-high revenue this year as we did last year. Consolidated operating income recorded KRW 1,349.3 billion, up 21.8% year-on-year, thanks to MNO's operating income turnaround and operating income improvement of media and commerce. The contribution of the new ICT businesses to earnings, excluding MNO increased 10 percentage points year-on-year, 24% as indicated that the new ICT businesses began to contribute not only to revenue but also through operating income. Net income is up by 74.3% year-on-year due to equity method income from SK Hynix. Let me now discuss major achievements and strategic direction for each business division. Nonconsolidated MNO revenue for 2020 recorded KRW 11,746.6 billion, up 2.8% year-on-year. Decline in roaming revenue due to the pandemic had a negative impact, but we achieved an annual revenue turnaround based on 5G subscriber growth and data usage increase. MNO operating income grew 7.5% year-on-year to record KRW 1,023.1 billion. While marketing expense and depreciation and amortization costs increased, revenue growth, backed by 5G expansion, led to a turnaround in operating income as well. In 2020, our MNO leadership was reconfirmed as we increased 5G market share and maintained #1 position through reasonable market operation and distribution innovation to cater to the non-face-to-face business environment. The 5G subscriber count stands at 5.48 million as of the end of 2020, which is expected to reach 9 million by the end of 2021. We will continue to increase the subscriber base with new services and seamless innovation while maintaining the stable market trend. This year, we will grow MNO business into an AI platform-based subscription service company based on FLO, wavve, cloud games and V Coloring, whose subscriber bases have been expanding. We plan to introduce various subscription products and services to go beyond the boundaries of mobile lines for smartphones. These subscription products will be offered not only to SK Telecom MNO customers but to everyone in Korea. In addition, we will create an AI-based subscription service platform with easy accessibility and restructure the membership programs. We are making all the necessary preparations to implement these plans because a subscription service company is the new goal and direction of MNO business for this year, and we will do our best to make this an opportunity to expand the scope of MNO business. Moving on to media. SK Broadband's consolidated revenue recorded KRW 3,713.5 billion. With the t-broad merger and IPTV subscriber growth, it rose by 17.2% year-on-year. Thanks to the record high revenue, operating income increased by 59.2% year-on-year, recording KRW 230.9 billion. Security business recorded KRW 1,338.6 billion in revenue. With sound growth of core business such as CMS and information security and new businesses such as home, parking and contactless solutions related to COVID-19, the revenue increased by 12.2% year-on-year. Operating income recorded KRW 140.9 billion, down 8.2% year-on-year due to reasons related to new business expansions. Commerce revenue recorded KRW 814.3 billion, up 12.1% year-on-year, thanks to GMV growth driven by the contactless business environment and strategic marketing drives. Operating income recorded KRW 11 billion, posting surplus for 2 consecutive years. 2020 was a year when we achieved greater volume and higher margin despite intensified competition in the commerce market. We will make efforts to strengthen the competitiveness of commerce business based on our experience last year. Next, Hyung-il Ha, Head of Corporate Center 2, will discuss the achievements and strategic direction for the new ICT businesses.
