While financial year 2023 represents the seminal year of our global expansion, it is the first full year where we entirely dedicate ourselves to bring our global business on a solid footing to penetrate into the selected markets. Financially, financial year 2023 is the first year of four full quarters of 100% revenues derived from international markets. Financial year 2023 marks a landmark year for us since we have proven that our business model can be successfully applied in different geographies across different continents. Right now, we are fully equipped to execute our vision of empowering each child to be able to speak to the world, one student at a time. During financial year 2023, we had just over 50,000 active students with attempted lesson consumptions and gross billings of $40 million, a long way from two years ago where we had booked less than $1 million. Looking ahead to 2024, we will continue to intensify our localization efforts in selected markets where we see large growth potential and benefit from an early mover advantage. Our guidance for the first quarter reflects our confidence in our growth trajectory. In terms of technology, our broad-based efforts to deploy AI-enabled tools to elevate the effectiveness of our human teachers is starting to bear fruits. Our teachers and learning consultants obtain more comprehensive and accurate quantitative student assessments to customize the customer's learning paths. In addition, we equip teachers with tools to engage with students more effectively and provide an elevated learning experience. As a consequence, our students will obtain more personalized exercises, are exposed to more immersive interaction, and benefit from more accurate assessments. With that, I will now turn the call over to Cindy, our CFO. Thank you, Jack. Fourth quarter net revenues were $7.7 million, a 2.2% sequential decrease driven by full-year drop. Gross margin for the fourth quarter was 75.6%. Gross billings grew by 1.1% quarter-over-quarter to $11.1 million. Q4 operating expenses were $10.4 million, an increase of 5.7% compared to the last quarter. Specifically, this has been driven by Q4 sales and marketing expenses of $7.6 million, a 10.7% sequential increase from Q3 due to further increases in marketing and branding spend. Q4 product development expenses were $0.9 million, flattish on a sequential basis. Finally, Q4 general and administrative expenses were $1.9 million, an 8.8% sequential decrease from Q3. Overall, Q4 operating loss was $4.6 million, while net loss was $4.6 million, a 19.1% and 19.4% sequential increase from Q3, respectively. Q4 GAAP and non-GAAP earnings per ADS were -$0.81 and $0.76, respectively. The company's total cash, cash equivalents, and time deposits were $23.4 million at the end of the fourth quarter. Advances from students were $27.4 million at the end of the fourth quarter. For more of our 2023 full-year financial results, please refer to our earnings press release for further details. Looking forward to the first quarter of 2024, we currently expect the net gross billing to be between $11.5 million and $12.0 million. The above outlook is based on our current market conditions and reflects the company's current and preliminary estimates of the market and operating conditions and customer demands, which are all subject to change. This concludes our prepared remarks. We will now open the line for questions. Operator, please go ahead. We will now begin the question- and- answer session.
