(1)The advances to its equity-accounted joint venture, together with the Company’s investment in the equity-accounted joint venture, form the net aggregate carrying value of the Company’s interests in the equity-accounted joint venture in these consolidated financial statements. As at December 31, 2022, the fair values of the individual components of such aggregate interests were not determinable. As at December 31, 2021, the Company's investment in its equity-accounted joint venture was written-down to its estimated fair value. At such time, the fair value of the Company's advance to its equity-accounted joint venture was estimated to approximate its carrying value.
