Thank you, Weng Ming. Let me first walk you through our unaudited second quarter and first half ended June 30, 2013, financial results, and then we can begin the Q&A session. Net revenue for the second quarter of 2013 was RMB 4.25 billion, USD 688.1 million, compared with RMB 3.43 billion in the second quarter of 2012. The increase in net sales was RMB 825.5 million, or 24.1%, as compared with the same period in 2012. The total number of engines sold during the second quarter of 2013 was 141,147 units compared with 109,329 units in the same quarter a year ago, representing an increase of 31,818 units or 29.1%. This was mainly attributable to an increase in the sales of engine for agriculture and truck applications. The increase in the sales of commercial vehicle was mainly due to the pre-buying of trucks prior to the implementation of the National IV emission standards nationwide on July 1, 2013. Gross profit was RMB 855.2 million, USD 138.4 million, compared with RMB 674.1 million in the second quarter of 2012. Gross margin was 20.1% in the second quarter of 2013 compared with 19.7% in the second quarter of 2012. A higher volume of engines was sold in the second quarter of 2013 compared with the same period a year ago, which enabled us to improve our gross margin. Other operating income was RMB 36.6 million, USD 5.9 million, an increase of RMB 25.0 million from RMB 11.6 million in the second quarter of 2012. The increase in income was mainly due to lower foreign exchange losses in the second quarter of 2013 compared with the same quarter last year. Research and development, R&D, expenses were RMB 115.9 million, USD 18.8 million, compared with RMB 95.3 million in the second quarter of 2012, an increase of 21.6%. As a percentage of net revenue, R&D spending declined to 2.7% compared with 2.8% in the second quarter of 2012. The lower percentage was due to higher net revenue in the second quarter of 2013 compared with the same quarter in 2012. Selling, general and administrative, SG&A, expenses were RMB 442.1 million, USD 71.6 million, up from RMB 380.4 million in the second quarter of 2012, an increase of RMB 61.7 million or 16.2%. SG&A expenses represented 10.4% of net revenue in the second quarter of 2013 compared with 11.1% in the same quarter a year ago. The decrease was mainly due to higher sales volume in the second quarter of 2013 compared with the same quarter in 2012. Operating profit increased by 58.9% to RMB 333.8 million, USD 54.0 million, from RMB 210.1 million in the second quarter of 2012, mainly due to higher gross profit and other income, partially offset by higher R&D and SG&A expenses. The operating margin was 7.8% compared with 6.1% in the second quarter of 2012. Finance costs declined to RMB 39.6 million, USD 6.4 million, from RMB 62.2 million in the second quarter of 2012, a decrease of RMB 22.6 million or 36.3%. The decrease was due to tax [ph] bill discounting, as well as lower interest costs relating to GYMCL's outstanding short-term financing bonds, STFB, and medium-term notes, MTN, compared with higher interest rates applicable to the outstanding STF in the second quarter of 2012. The share of joint ventures was a loss of RMB 10.0 million, USD 1.6 million, compared with loss of RMB 6.2 million in the second quarter of 2012. In the second quarter of 2013, total net profit attributable to China Yuchai's shareholders was RMB 166.3 million, USD 26.9 million, or earnings per share of RMB 4.46, USD 0.72, compared with RMB 67.1 million or earning per shares of RMB 1.80 in the same quarter in 2012. May I now move on to the financial highlights for the 6 months ended June 30, 2013. For the 6 months ended June 30, 2013, net revenue was RMB 8.10 billion, USD 1.31 billion, compared with RMB 7.11 billion in the same period last year. The increase in net sales was RMB 987.2 million or 13.9% as compared with the same 6-month period in 2012. The total number of diesel engines sold by GYMCL during the first 6 months of 2013 was 271,891 units compared with 241,026 units in the same period last year, representing an increase of 30,865 units or 12.8%. This increase was mainly attributable to an increase in the sales of engine for agricultural and truck applications second quarter of 2013. The increase in sales of commercial vehicles was mainly due to the pre-buying of trucks prior to the implementation of the National IV emission standards nationwide on July 1, 2013. Gross profit was RMB 1.63 billion, USD 264.2 million, compared with RMB 1.45 billion in the same period last year. Gross profit margin decreased to 20.2% in the first 6 months of 2013 as compared with 20.4% a year ago. This was mainly attributable to a shift in the sales mix to more light-duty engines, as well as engine for agriculture applications with lower gross margins. Other operating income was RMB 57.5 million, USD 9.3 million, an increase of RMB 19.8 million from RMB 37.7 million in the same period last year. This increase was mainly due to a smaller loss relating to the disposal of plant and equipment as compared with the same 6-month period in 2012. Research and development, R&D, expenses were RMB 210.7 million, USD 34.1 million, compared with RMB 177.2 million in the same period in 2012, an increase of 19.0%. As a percentage of net revenue, R&D spending rose to 2.6% compared with 2.5% in the same period last year. The R&D expenses mainly related to the ongoing development of new and existing engine products, as well as continued initiatives to improve engine quality. Selling, general and administrative, SG&A, expenses were RMB 806.6 million, USD 130.5 million, up from RMB 756.7 million in the same period last year, an increase of RMB 49.9 million or 6.6%. SG&A expenses represented 10.0% of net revenue for the 6 -- for the first 6 months of 2013 compared with 10.6% in the same period last year. The decrease in the SG&A percentage was mainly due to higher sales in the first 6 months of 2013 as compared with the same period in 2012. Operating profit increased to RMB 672.7 million, USD 108.9 million, from RMB 557.3 million in the same period last year mainly due to an increase in the gross profit and other income, partially offset by higher R&D and SG&A expenses. The operating margin was 8.3% compared with 7.8% in the same period last year. Finance costs declined to RMB 73.8 million, USD 11.9 million, from RMB 137.5 million in the same period last year, a decrease of RMB 63.7 million or 46.3%. The decrease was due to less bill discounting and lower interest costs relating to the outstanding STFBs and MTNs. The share of joint ventures was a loss of RMB 25.7 billion, USD 4.2 million, compared with a loss of RMB 22.9 million in the same period last year.
