* Xinjiang Daqo Investment became the Group’s subsidiary since December 20, 2018 and was consolidated into the Group’s financial results as of December 31 2018, 2019 and 2020, accordingly its transaction in 2019 and 2020 will not be presented as related party transaction.

In 2020, Nanjing Daqo Transformer and Chongqing Daqo Tailai agreed to postpone the Group’s payables to them with no interest cost charged for the support on the Company’s working capital. Accordingly, the unrecognized financing expense of $0.8 million resulting from this debt restructuring was recognized as additional paid in capital.

In June 2020, the Group sold 4.4% of Xinjiang Daqo’s shares at the aggregate consideration of $28.1 million based on the fair value of Xinjiang Daqo to its directors, Mr. Guangfu Xu, Mr. Xiang Xu, Mr. Dafeng Shi and Mr. Longgen Zhang.
