(*) Refer to changes in the equity of investees, as their financial statements for the year ended December 31, 2019 were issued, including some adjustments, after the Company’s financial statements. (¹) The amounts presented for 2020 refer to July 31, 2020. (²) On August 20, 2020, the investee Saneaqua Mairinque held an Extraordinary Shareholders' Meeting that approved a capital increase in the amount of R$ 21,944, through the issue of 17,178,988 shares. SABESP waived its preemptive right in the participation of such capital increase, and the shares then issued because of the capital increase were entirely subscribed by the shareholder BRK Ambiental, resulting in the dilution of SABESP’s interest in the investee. Accordingly, SABESP discontinued the equity accounting method and recorded this financial asset under the fair value on the transaction date, in the amount of R$ 5,734 recorded as “Other investments”. The amounts corresponding to the equity result were recorded until July 2020.
