Thank you, Fu-Fu, and hello, everyone. Welcome to our first quarter of 2018 earnings conference call. For the first quarter of 2018, the overall market remain competitive. In mobile business, we continue to retain our market leading position in both subscriber numbers and revenue. We are pleased to see the continuous mitigation of subscriber loss. And we would maintain the voice and mobile service revenue decrease year-over-year among three major telecoms in Taiwan. In our broadband business, we are encouraged to see subscriber net adds turned positive. For the first quarter, we demonstrate the success of our strategy of promoting home centric services that bundle broadband, Wi-Fi, MOD in IoT services to further solidify our broadband subscriber base. Meanwhile, MOD subscriber numbers and the revenue continue to grow in the first quarter as we have been endeavoring to facilitate the overall TV operational environment and introducing popular content as well as OTT service. Despite the decrease of ICT revenue year-over-year in the first quarter owing to some delays in gradual revenue recognition, we observe that revenue share from enterprise customers continue to increase as that kept enhancing our overall capabilities to provide ICT related solutions to our enterprise customers. Our IoT platform continue to support development of smart city, smart agriculture, smart manufacturing and other IoT related applications. We also furthered our efforts to increase network capacity by joining the construction of SJC2 consortium submarine cable in March. And in February, our highest-rated IDC in Banqiao completed the second phase of its construction and open to customers. We are pleased to report that so far 70% of the newly constructed space has been sold or reserved. Going forward, we will continue to leverage our advantages in IDC and CDN to cater to the growing demand of comprehensive Internet services in the digital economy. Now I will walk you through each of our business lines. On Slide 5, I would like to update you on our mobile business. As of March 2018, our total number of 4G subscribers has exceeded 8.2 million and mobile Internet adopters continue to grow reaching 84.4% of total postpaid subscription, which consequently drove up our mobile Internet revenue by 3.04% year-over-year. However, the overall mobile revenue for the first quarter is decreased year-over-year mainly due to the accounting measure change from IFRS 15 adoption. Factoring out the impact of IFRS 15, we still see a decrease in mobile service revenue due to the increasingly competitive market landscape. Despite intense competition, we are delighted to see that mobile subscriber loss has been mitigated quarter-over-quarter due to improvements in our customer retention. Going forward, we will continue to roll out incentives for existing customers. And further respond to market dynamics in a flexible way to consolidate our subscription base. Slide 6 shows the performance of our broadband business. For the first quarter, we are encouraged to see our broadband subscriber net adds turn positive with 0.3% increase year-over-year. In addition, we continue to see a migration of our broadband subscribers to higher speed fiber services. We are pleased with the number of users signing up for connected speeds of 100 megabit per second or higher which grew by 10.7% year-over-year to 1.32 million in the first quarter. We expect to improve this number by upselling highest bid offerings and differentiating our products by bundling digital convergence services. To incentivize customers to migrate to higher speed services, we roll out a short-term promotion plan for 300-megabit per second services in the first quarter. Going forward, we will continue this strategy and stay ahead of our competitors by enhancing user stickiness on our network through smart home services and that leverage our Wi-Fi advantages as well as MOD and OTT offerings. Now let's move into -- on to Slide 7. We are glad to report another robust quarter for the IPTV business. Our IPTV/MOD platform became the largest video platform in Taiwan with 1.7 million subscribers in the first quarter of 2018, that representing a 27.4% increase year-over-year. Our IPTV revenue continue its growth trajectory as well with a 25.2% increase year-over-year primarily driven by the healthy growth of IPTV and SVOD subscribers. We are pleased to see that the number of SVOD subscribers exceeded 1 million in the first quarter and customers continue to sign up for additional SVOD programs. In addition to our on-demand service, we plan to leverage popular sport event such as the upcoming 2018 FIFA World Cup and eSports to further expand our channel subscription base and enhance the popularity of 4K quality viewing. Going forward, the quality and the diversification of our IPTV content offerings will continue to be our priority. In order to further strengthen user acquisition and user stickiness, we will also carry more OTT offerings to increase customers' total contribution to our revenue. Please turn to Slide 8 for an update on our ICT initiatives. In the first quarter of 2018, our ICT revenue decreased year-over-year owing to some delay in revenue recognition. The IoT platform continue to demonstrate the latest solutions including applications in smart agriculture, smart manufacturing and the smart transportation. And the number of our overall IoT connected device has exceeded 500,000 as well. Our highest-rated Banqiao IDC finished its second phase rack installation in February and currently enjoys satisfactory occupancy rate of 70% so far. Going forward, we remain committed to leveraging our competitive advantages in network infrastructure, IDC and CDN to offer reliable, customized and comprehensive ICT solutions to our enterprise customers. We also aim to develop new opportunities in our innovative business lines with advanced technologies such as AI, blockchain and information security and seek partnerships to establish a comprehensive ecosystem in this sector. Now I would like to hand over the call to Mr. Kuo for our financial results.
