As of December 31, 2018 and 2019, loans receivables are primarily personal loans made to home purchasers, home owners and Registered Agents and the Group’s employees. These loans have an original term from 30 days to 5 years and carry interest rates between 3.6%~24% per annum.

On December 25, 2017, the Group entered into a one-year arrangement with an independent third party trust, under which the Group would refer home owners on their platform to obtain personal loans from the trust. The Group is entitled to a loan facilitation fee ranging from 0.8% to 4% of the amounts of completed loan transactions. The personal loans are secured by the home owners’ properties. The Group provided guarantee on the principal and interest repayment of the loans to the trust and committed to purchase all the unpaid loans principal and accrued interests due from the home owners upon the end of the arrangement on December 25, 2018. Such guarantee was accounted for a derivative during the one-year agreement period under ASC 815 and the Group has determined that its fair value to be immaterial. On December 25, 2018, the Group purchased from the trust, pursuant to the arrangement, unpaid secured loans at a consideration of RMB21,424, determined based on the outstanding principal and interest payable by the home owners. These loans have been recorded in secured loans receivables of RMB21,424 and RMB14,760 on the consolidated balance sheet as at December 31, 2018 and 2019, with an allowance of doubtful loans of RMB3.1 million was made as of December 31, 2019.

The allowance for loan losses is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. Management performs periodic evaluation of the adequacy of the allowance. The allowance is based on the Group’s past loan loss history, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, composition of the loan portfolio, current economic conditions and other relevant factors. The allowance is calculated at portfolio-level since the loans portfolio is typically of smaller balance homogenous loans and is collectively evaluated for impairment. In estimating the probable loss of the loan portfolio, the Group also considers qualitative factors such as current economic conditions and/or events in specific industries and geographical areas, including unemployment levels, trends in real estate values, peer comparisons, and other pertinent factors such as regulatory guidance.
