(i) In October 2020, Millicom granted a shareholder loan of $193 million to Guatemala (out of which $39 million is due after more than one year as of December 31, 2020). The loan bears interests at 4% p.a. and is repayable by January 13, 2022, at the latest. Together with other shareholder and external financings, the proceeds were used to repay the $800 million aggregate principal amount of its outstanding 6.875% Senior Notes due 2024 (note A.2.2.). (ii) In November 2020, our operations in Honduras completed a shareholding restructuring whereby Telefonica Cellular S.A. acquired the shares of Navega S.A. de CV from its existing shareholders. The sale consideration will be payable in several installments with a final settlement in November 2023. As of December 31, 2020, $51 million out of a total receivable of $79 million is due after more than one year and therefore disclosed in non-current assets. The disposal also triggered the recognition of a net gain of $ 4 million, under ‘Other operating income (expenses), net’ in the Group's statement of income, corresponding to the portion of gain realized on the unrelated investors' interests in the joint venture (i.e. 33.33%). (iii) In 2020, and as a result of the significant deterioration of the credit risk of AirtelTigo Ghana, combined with other unfavorable economic factors, Millicom concluded that this related party loan was underperforming and should be impaired. As a consequence, the Group fully impaired this receivable of $45 million during the year, disclosed under ' Other operating income (expenses), net' in the income statement.
