Thank you, all, for joining us today on our earnings conference call for the fourth fiscal quarter and the full FY 2015. We are pleased with our fourth quarter and full fiscal year results that reflect the continued strong growth momentum for small class in the outer cities. Due to high demand for our tutoring services, we expanded small class classroom capacity by over 50% in FY 2016 compared to the previous year, and managed higher utilization rates throughout the year. In renminbi terms, full-year revenue growth was [46.5%]. Today, I will briefly review our operational progress in the fourth quarter, and also offer you some highlights for the full fiscal year. After that, I will provide some further analysis of the Q4 and the full fiscal year financials and our business outlook. We had a strong performance on the top line in the fourth quarter, supported by ongoing capacity expansion with the high demand. In dollar terms, the fourth-quarter net revenue grew by 42.1% year over year to $175.0 million. And in renminbi terms, the top-line growth was 49%, both exceeding our expectations. Revenue growth was primarily driven by our 57% year-over-year growth in enrollments across all cities. We also achieved solid year-over-year non-GAAP operating income growth of 25.2% in the fourth quarter. Small class revenue growth was strong across the board. Small class revenue accounted for 84% of total revenue in the fourth quarter compared to 80% in the same year-ago period, and was up by 48.4% in dollar perspective, and 55.6% in renminbi terms, where enrollments increased by 58%. Revenue generated from cities other than the top five, Beijing, Shanghai, Guangzhou, Shenzhen and Nanjing, accounted for 33% of Peiyou small class revenues compared to 23% in the same quarter last year, reflecting the faster growth dynamics in all tier cities. In the fourth quarter, revenue from cities outside the top five grew by over 100% year over year, and we achieved a triple-digit percentage growth in 10 cities. These cities are: Chengdu, Hangzhou, Jinzhou, Suzhou, Chongqing, Shenyang, Jinan, Shijiazhuang, Qingdao and Changsha. In the winter term across the Group, we saw robust growth in all core subjects of our tutoring service. In particular, Chinese and English subjects achieved an enormous growth of above 50% year over year, faster than average growth. We will expand our English and Chinese core offering to more cities, and expect the strong growth momentum to continue in the future. Let me update you on Beijing's small class performance. We are very pleased that we have managed a robust recovery in Beijing enrollments in all subjects following our targeted summer promotions last year. As the growth in enrollments came back, we also worked on re-energize the team, revise accounts, and better optimize greater operational efficiencies such as the optimization of small class centers. We continue to take the initiatives that will further strengthen our basis for growth in Beijing, and secure our place in the top ranking of the industry players and the potential consolidators in this market. Turning briefly to our one-on-one business. One-on-one contributed a 12% of our revenue in Q4 compared to 16% in the same year-ago period. As I mentioned last quarter, we continue to expand our one-on-one presence where needed as a supporting business for small class. In the fourth quarter, we opened one new one-on-one learning center in each of Jinzhou and Suzhou, two cities we entered in 2012. Let me now turn to our online courses segment which remains one of our fastest-growing sectors with 55% year-over-year revenue growth in US dollars and 63% in renminbi terms. Online courses through xueersi.com contributed 4% of total revenue this quarter and changed from the year-ago period. Online enrolments were 14% of the total enrolments this quarter versus 13% in the same year-ago period. Let me update you on our capacity expansion. Because of a much stronger demand for our tutoring services this past year, we expanded more than originally planned. To support our healthy expansion, we have reinforced the training programs for new teachers. We are very proud of our training team that enables us to uphold the outstanding tutor quality that TAL is known for. During the fourth quarter, we opened 23 new Peiyou small class learning centers, [ran more] these small class learning centers, and added classrooms in existing centers in cities with a strong demand and high utilization rates, such Wuhan, Beijing, Guangzhou, Nanjing, Xi'an, and other cities. Overall, we added a net 305 Peiyou small class classrooms in the fourth quarter. In addition, we opened two one-on-one learning centers. We also closed five small class learning centers in line with our long-term objective to build a network of larger-sized centers with good efficiency and utilization. In the first quarter of the current FY 2017, we are going to maintain the faster pace in network expansion, and add between 20 and 35 small class learning centers in the cities where the market demand is particularly high. We incorporated the learning centers into our physical network from the newly-acquired business unit, Firstleap Education. By the end of the fourth quarter, our network covered the 246 Peiyou and Mobby small class learning centers, 41 Firstleap small class learning centers, and 76 one-on-one learning centers. Let me now go over some of the full-year highlights. Full FY 2016 has been a year of excellent growth performance. In the renminbi terms, revenues increased 46.% year over year, and in dollar terms, the top-line growth was 42.9% to $600.19 million, ahead of our expectations. Total student enrolments increased by [55%] (Ph) year over year to 2.3 million. We also achieved solid year-over-year non-GAAP operating income growth of 29.4% for the full fiscal year, even as we made significant investments in our future growth. For full FY 2016, let me briefly recap our progress for each business segment where our core small class offering continued to be the main driver of our growth, up by 48.0% in US dollars, and 51.9% in renminbi terms. Enrollment growth for small class increased [53.5%] (Ph) over the previous fiscal year. ASP for small class in renminbi terms was almost flat year over year for the full-year. Small class accounted for 83% of total revenue, up from 80% last year. The year-over-year change in revenue contribution was mostly driven due to the ongoing robust growth in under-penetrated cities. We are pleased with this accelerated revenue growth in both Beijing and outside cities. Revenue generated from cities outside the top five accounted for 32% of total Peiyou small class, and was up by 96% year over year. In FY 2016, we raised small class prices in five cities, in Xi'an, Wuhan, Qingdao, Chongqing and Shenyang. In FY 2017, we will maintain premium pricing, and plan to increase small class prices in cities including Beijing, Guangzhou, and several other cities. In FY 2016, we added 44 Peiyou and Mobby small class learning centers on a net basis, or 1,512 Peiyou and Mobby small class classrooms, which represented 51% of classroom capacity expansion versus the previous year. One-on-one achieved mid-teen revenue growth and represented 13% to total revenue in the full-year of FY 2016 compared to 17% in FY 2015. One-on-one revenue growth was 17% in renminbi terms and 14% in US dollars, driven by a 26% enrolment growth, taking into consideration of the transfer of our Guangzhou-based one-on-one business to Changing Education. Online course revenue grew by 61% in US dollars and 65% in renminbi terms for the fiscal year. Online courses represent 4% of total revenue and 17% of total enrollments. In FY 2016, we spent a total of $22.5 million budget on organic and new business initiatives aligned with our original budget. We are pleased with the structural progress in our O2O and online business based on the positive initial results, excluding enrolment growth. Going forward, we will maintain similar levels of investment in O2O and online initiatives, and we expect the O2O and online contribution to become more meaningful in FY 2017. For FY 2017, we plan to strategically stay the course of the past year, which is to fulfill further growth based on expansion and technology-based innovation with the right balance between present and future growth. We will further build on our O2O initiatives, and at the same time continue to expand the center capacity to meet the strong demand for our class-based tutoring. Based on the outstanding progress we have made this past fiscal year, we are confident that our ongoing efforts to [coverage] technology, communication and education resources, will help us become a leading technology-based education services provider in China. Let me now review our financial performance in more detail, followed by some comments on our business outlook. Now let me go over some financial points I would like to highlight. In the fourth fiscal quarter, small class ASP renminbi terms was almost flat year over year. We expect ASP of the regular small class to rise by low single-digit percentage in FY 2017 after we raise price in the aforementioned cities. One-on-one ASP was down by 1.9% due to the increasing enrolment contribution from the small group class which charge lower hourly price. We expect small group class to continue to gain popularity in future and lower ASP of our one-on-one business. Online course ASP was almost flat year over year in renminbi terms in the fourth quarter. In the fourth quarter, gross profit was $86.3 million as compared to $64 million for the same year-ago period. Gross margin for the fourth quarter was 49.3% as compared to 52.0% for the same period of last year, due to accelerated expansion, capacity expansion, and teacher recruitment for the coming summer term. Operating income of $16.6 million represented a year-over-year increase of 12.1%. Non-GAAP operating income increased by 25.2% year over year to $25.2 million. Basic and diluted net income per ADS were $0.14 and $0.13 respectively for the quarter. Non-GAAP basic and diluted net income per ADS, which excluded share-based compensation expenses, were $0.24 and $0.23 respectively. In FY 2016, GAAP and non-GAAP income from operations increased by 26.5% and 29.4% respectively year over year. Non-GAAP operating margin of 17.9% aligned with our expectation. Income tax expense was $33.5 million in FY 2016 compared to $9.4 million in FY 2015. The increase was mainly due to accrued one-off income tax expense of $12.5 million related to a gain from disposal of one-on-one business in Guangzhou and an increase of $7.3 million in income tax expense due to the expiration of an EIT exemption period for one of TAL's subsidiaries, Beijing Xintang Sichuang Education Technology Co., Ltd., upon which the subsidiary became subject to an EIT rate of 12.5%. Basic and diluted net income per ADS were $1.29 and $1.21 for FY 2016. Non-GAAP basic and diluted net income per ADS, which excluded share-based compensation expenses, were $1.61 and $1.49 respectively. From the balance sheet, as of February 29, 2016, we had $434.0 million of cash and cash equivalents, and $17.3 million of term deposits compared to $470.2 million of cash and cash equivalents and $21.2 million of term deposits as of February 28, 2015. Capital expenditures for FY 2016 were $35.1 million, representing an increase of $4.5 million from $30.6 million the same year-ago period. As of February 29, 2016, our deferred revenue balance was $289.3 million as compared to $177.6 million as of February 28, 2015, representing a year-over-year increase of 62.8%. Taking into consideration the recent significant change in the renminbi exchange rate against the US dollar, based on our current estimates, total net revenues for the first quarter of FY 2017 are expected to be between $181.1 million and $183.2 million, representing an increase of 40% to 42% on a year-over-year basis. If not including the impact from the recent depreciation of renminbi against the US dollar, the projected revenue growth rate is expected to be in the range of 45% to 47% for the first quarter of FY 2017. These estimates reflect our current expectation which is subject to change. That concludes my prepared remarks. Operator, we are now ready to take questions.
