No payments were received from Middlemount during the year ended December 31, 2020. One of the Company’s Australian subsidiaries is party to an agreement to provide a revolving loan to Middlemount. The Company’s participation in the revolving loan will not, at any time, exceed its 50% equity interest of the revolving loan limit, which was $50 million Australian dollars at December 31, 2022. The revolving loan bears interest at 10% per annum and expires on December 31, 2023. There was no outstanding revolving loan at December 31, 2022 or 2021.
