20:14 Thank you, Mr. Zhai and thank you everyone for joining us today. I will welcome you to our fourth quarter of 2021 financials [indiscernible] fiscal year of 2021. We believe year-over-year comparisons is the best way to review our performance. Unless otherwise stated, all percentage changes I’m going to give will be on GAAP basis. Also, unless otherwise stated, all numbers I'm going to give will be in RMB. 20:45 In the fourth quarter of 2021, total loan origination volume was 3 billion during the fourth quarter of 2021, representing an increase of 15% from 2.7 billion. Interest and financing service fees on loans increased by 7% to 448 million, as compared to RMB417 million, primarily due to the increase in the balance of average daily outstanding loan principal. 21:19 Total interest and fees expense increased by 29% to 205million, as compared to 159 million, primarily due to the increase in the principal of other borrowings, as well as the funding cost from trust companies. Collaboration cost for sales partners, representing sales incentives paid to sales partners, increased to 120 million, as compared to 104 million, primarily due to the increase in average daily outstanding loan principal under the collaboration model as compared to the same period of 2020. 22:03 Provisions for credit losses recorded a reversal of 308 million, as compared to a reversal of 31 million, primarily due to the combined effect of: first, higher loss given default, LGD, under the current expected credit loss, CECL model, which takes into account the company's historical data of actual loss in the past few years; and second, the fact that the company transferred loans under the traditional facilitation model to third parties in bulk during the fourth quarter of 2021 and the allowance of such loans was reversed. 22:45 Net losses on sales of loans were 469 million compared with a net gain of 44 million, primarily attributable to the fact that the company transferred loans under the traditional facilitation model to third parties in bulk during the fourth quarter of 2021. Such loans were all facilitated prior to 2019, and the majority of them were long past due and therefore sold at a large discount. 23:18 Total operating expenses decreased by 8% to 106 million, compared with 115 million. Income tax expense was 15 million as compared to an income tax expense of 24 million, primarily due to the fact that the company recorded a loss before income tax for the fourth quarter of 2021, such loss was due to the loss associated with the sale of loans under the traditional facilitation model in bulk during the fourth quarter of 2021. Net losses was 105 million as compared to a net income of 105 million. 24:00 Now, let's me move on to the financials of 2021 as a whole. Total loan origination volume was 13 billion, representing an increase of 46% from 9 billion. Interest and financing service fees on loans decreased by 3% to 1,770 million as compared to RMB1,829 million, primarily due to the lowered interest rate on loans facilitated in an effort to comply with rules and regulations issued by relevant PRC regulators, including the decisions of the Supreme People's Court to Amend the Provisions on Several Issues concerning the Application of Law in the Trial of Private Lending Cases issued in August 2020. 24:55 Interest and fees expenses increased by 6% to 776 million, as compared to 731 million, primarily due to the increase in the principals of other borrowings, as well as the funding cost from trust companies. Collaboration cost for sales partners increased to 426 million, as compared to RMB415 million, primarily due to the increase in average daily outstanding loan principal under the collaboration model as compared to the same period of 2020. 25:34 Provision for credit losses recorded a reversal of 279 million, as compared to RMB278 million, mainly due to the combined effect of: first, the fact that the company transferred loans under the traditional facilitation model to third parties in bulk during the fourth quarter of 2021 and the allowance of such loans was reversed; second, the higher loss given default under the current expected credit loss model, which takes into account the company's historical data of actual loss in the past few years, partially offset by; third, the lower probability of default under the current expected credit loss model, which takes into account the outlook of a more positive economy growth of China in the fiscal year of 2021 as compared to that of the same period of 2020 under the impact of COVID-19 pandemic. 26:44 Other gains, net was 50 million, compared with 20 million. When a loan defaults and the sales partner chooses to repurchase such loan in installments, the company would charge certain percentage of the loan as the fund possession fee. The increase in other gains for fiscal year of 2021 was mainly due to the fact that there was a larger number of cases where delinquent loans were repurchased by the sales partner in installments, which led to an increase in fund possession fee received by the company. 27:21 Total operating expenses decreased by 15% to 381 million, as compared to 449 million. Income tax expense decreased by 40% to 29 million, as compared to 48 million, primarily due to the decrease in the amount of taxable income. Net income decreased by 43% to 65 million as compared to RMB115 million. 27:50 Total outstanding long during the quarter was 10 billion as of December 31, 2021, as compared to 10 billion as of December 31, 2020. As of December 31, 2021, the company held cash and cash equivalents of 2.2 billion, compared with RMB2 billion as of December 31, 2020, including RMB1.5 billion and [RMB1 billion] [ph] from structured funds, which could only be used to grant new loans and activities. 28:30 The actual delinquency rate for loans originated by the company increased to 24.1% as of December 31 from 22.6%. Under the collaboration model, the actual delinquency rate for first lien loans increased to 29.1% as of December 31, 2021 from 18%, and the actual delinquency rate for second lien loans increased to 19.5% as of December 31, 2021 as compared to 15.6%. 29:11 The actual NPL rate for loans by the company decreased to 9.4% as of December 31, 2021 from 11.7%.
