  1. The equity investments ascribed to China Fusion Energy Co., Ltd. and Energy Singularity are reported as Registered Capital, defined in China’s Company Law as the amount of capital that shareholders pledge to contribute to a company. Unlike typical stock purchase agreements, Registered Capital does not necessarily involve an immediate transfer of funds, but it still represents equity-like, at-risk capital. For the purposes of this graph, we therefore classify it as an equity investment supporting the pursuit of commercial fusion energy. ↩↩
