[1] | The transactions in 2018 referred to the investments transferred to an entity controlled by the Group’s major shareholders. In June 2019, to focus the Company’s efforts and resources on its core businesses, the Company transferred several equity investments of the Group to an investment fund. The Group contributed a total of RMB220.0 million cash into this fund as a limited partner, which is accounted for as an equity method investment. The cost of the equity investments transferred was RMB465.8 million. The consideration was RMB539.6 million, which was based on the estimated fair value of the investments. The difference between the consideration and cost of the investments was recognized as investment income. In July 2020, the Company acquired certain equity interests of two investments from the investment fund. The consideration was RMB110.0 million. The balances due from an investment fund as of December 31, 2019 and December 31, 2020 were consideration receivables related to the equity investments transferred in 2019 and dividend receivables, which is non-trade in nature.
