Thank you, Mike, and good afternoon. It's my pleasure to be on the call today to give you an update on our results across the major market segments. Let me start with Computing. It represented 48.5% of total revenue in the December quarter. We posted a 10.8% sequential increase and a 26% growth year-over-year. We continued to grow our Computing business by expanding our BOM content in various computing applications. Our high-value DrMOS Power IC products continued to gain market share into the Vcore application. We achieved major design wins in the latest graphics card platform and further diversified our business into the Add-In-Card market. In addition, we expanded our footprint at our new global brand OEM to the tablet application and we began to ship parts for these high-end tablets during the December quarter. Please note that this particular tablet battery protection business was originally tied to the same customer name in our Communication segment when we gave guidance last quarter. To better align our product categories with our business segments, we separated this new tablet business and moved it from the Communication segment to the Computing segment. The CPU shortage in 2018 did not have a major impact on our business because processors were prioritized to support higher value big core systems. The shortage is expected to affect more PC applications in the March quarter, but it is expected to be resolved in the June quarter. Accordingly, we are adjusting our forecast of Computing business marginally down for the March quarter. Now, let's discuss the Consumer segment, which was 16.2% of total revenue. As expected, this segment declined 12.7% sequentially and 12% year-over-year. The declines were due to seasonality in TV and weakness in Chinese home appliance markets. Despite the appliance weakness, our IGBT line continued to gain traction in design activities, drawing on the strength of our optimized devices that increase power efficiency in motor applications. IGBT grew more than 40% in calendar year 2018 and is on track for a similar increase in calendar year 2019. During the December quarter, we gained market share in refrigerator applications and won new customers in the Chinese home appliance market. For TV applications, we secured design wins in premium TVs, which represent significantly higher BOM content for us. We are now ramping these TV products in the March quarter. In this context, we allocated more capacity and expect healthy growth in the Consumer segment for the March quarter. Now, let's turn to the Power Supply and Industrial segment. This segment was 19.4% of total revenue, up 2.1% sequentially and up 6.7% year-over-year. We see continued favorable momentum in our high performance medium voltage product line. Quick charger and USB PD charger applications are moving to even higher power levels by increasing voltage and current. This trend requires more efficient MOSFETs, thereby commanding higher selling prices, while leaving fewer players in the market. We believe we are well positioned to benefit from this trend and encouraged by the ongoing share gains of our medium voltage products. Even with near-term softening in the smartphone market, we expect our quick charger business to expand in calendar year 2019. In accordance with our product mix management activity, we expect to see a slight decrease in this segment sequentially in the March quarter. Finally, let's discuss the Communication segment, which was 13.8% of revenue in the December quarter. Segment revenue dropped 11% sequentially and increased 9.4% year-over-year. Keep in mind that the new tablet battery protection business was moved into Computing segment, which impacted growth rates. Without it, the December revenue came in line with our expectation. The weakness in global smartphone market is further deteriorating as smartphone makers are adjusting their inventories. During the December quarter, we partially offset the overall slowdown in Chinese smartphone demand with the ramp of production for the new global customer that we added in the September quarter. We also won an additional global smartphone OEM in the December quarter, which will gradually ramp in the March quarter. In parallel, we secured multiple design wins in enterprise telecom equipment for 5G. Our medium voltage products are specifically designed to deliver robust performance in telecom base stations. We did not participate actively in the past 4G deployment, so we are very excited about the new opportunities ahead of us as the industry moves forward with the 5G ramp. Demand for our telecom equipment products should grow in the March quarter, thus partially offsetting the smartphone headwinds combined with seasonal slowness. While we are confident that our Communication segment will rebound starting from the June quarter, we expect this segment to trough in the March quarter. With that, I will now turn the call over to Yifan for the guidance.
