CI% stands for capital injection percentage. It refers to the percentage relative to the NAV at which the firm injects new capital into an MSA.
A higher value will result in the ATSR having more money to trade with, which can lead to greater profits. However, a higher capital injection rate also increases the risk for the firm, as it is providing more money to the ATSR to trade with.
Eon Labs Ltd. will not inject capital into an MSA unless they reach a certain performance level as detailed in Evaluation, thus aligning the interest of the ATSR with the firm.
