LOAN PAYABLE	8. LOAN PAYABLE Entrusted Loan Payable (HYREF Loan) The HYREF Fund was established in July 2013 with a total fund size of RMB 460 million ($77 million) invested in Xi’an Zhonghong for Zhonghong’s three new CDQ WHPG projects. The HYREF Fund invested RMB 3 million ($0.5 million) as an equity investment and RMB 457 million ($74.5 million) as a debt investment in Xi’an Zhonghong; in return for such investments, the HYREF Fund was to receive interest from Zhonghong for the HYREF Fund’s debt investment. The loan was collateralized by the accounts receivable and the fixed assets of Shenqiu Phase I and II power generation systems; the accounts receivable and fixed assets of Zhonghong’s three CDQ WHPG systems; and a 27 million RMB ($4.39 million) capital contribution made by Xi’an TCH in Zhonghong. Repayment of the loan (principal and interest) was also jointly and severally guaranteed by Xi’an TCH and the Chairman and CEO of the Company. In the fourth quarter of 2015, three power stations of Erdos TCH were pledged to Industrial Bank as an additional guarantee for the loan to Zhonghong’s three CDQ WHPG systems. In 2016, two additional power stations of Erdos TCH and Pucheng Phase I and II systems were pledged to Industrial Bank as an additional guarantee along with Xi’an TCH’s equity in Zhonghong. The term of this loan was for 60 months from July 31, 2013 to July 30, 2018, with an interest rate of 12.5%. On August 6, 2016, Zhonghong was required to repay principal of RMB 280 million ($42.22 million), of which the Company paid RMB 50 million ($7.54 million); while on August 6, 2017, Zhonghong was initially supposed to repay principal of RMB 100 million ($16.27 million) and on July 30, 2018, Zhonghong was initially supposed to repay the remainder of RMB 77 million ($12.52 million). During the term, Zhonghong was to maintain a minimal funding level and capital level in its designated account with the Supervising Bank to make sure it has sufficient funds to make principal payments when they are due. Notwithstanding the requirements, the HYREF Fund and Supervising Bank verbally notified Zhonghong from the beginning that it was unlikely that they would enforce these requirements for the purpose of the efficient utilization of working capital. The Company had paid RMB 50 million ($7.54 million) of the RMB 280 million ($42.22 million), and on August 5, 2016, the Company entered into a supplemental agreement with the lender to extend the due date of the remaining RMB 230 million ($34.68 million) of the original RMB 280 million ($45.54 million) to August 6, 2017. During the year ended December 31, 2017, the Company negotiated with the lender again to further extend the remaining loan balance of RMB 230 million ($34.68 million), RMB 100 million ($16.27 million), and RMB 77 million ($12.52 million) (which included investment from Xi’an TCH of RMB 75 million and was netted off with the entrusted loan payable of the HYREF Fund in the balance sheet). The lender had tentatively agreed to extend the remaining loan balance until August 2019 with an adjusted annual interest rate of 9%, subject to the final approval from its headquarters. The headquarters did not approve the extension proposal with an adjusted annual interest rate of 9%; however, on December 29, 2018, the Company worked out with the lender an alternative repayment proposal as described below. As of December 31, 2018, the entrusted loan payable had an outstanding balance of $59.29 million, of which, $10.92 million was from the investment of Xi’an TCH; accordingly, the Company netted the loan payable of $10.92 million with the long-term investment to the HYREF Fund made by Xi’an TCH. As of March 31, 2021, the interest payable for this loan was $10.07 million and the outstanding balance for this loan was $22.05 million including a non-current portion of $0.30 million. As of December 31, 2020, the interest payable for this loan was $10.14 million and the outstanding balance for this loan was $22.20 million including a non-current portion of $0.30 million.
