​ Equity Method Investments The Company’s investment in the 7Ridge Investments 3 LP (“7Ridge Fund”), represents a nonconsolidated variable interest entity (“VIE”). The Company has determined that consolidation of the VIE is not required as the Company is not the primary beneficiary of the 7Ridge Fund, as it does not have controlling financial interest and lacks the ability to unilaterally remove the general partner, 7Ridge Investments 3 GP Limited, direct material strategic decisions, or dissolve the entity (i.e., the Company does not have unilateral substantive “kick-out” or “liquidation” rights). The Company’s interest in the 7Ridge Fund is equal to the carrying value of the investment as of March 31, 2023, or $231.9 million, which includes periodic capital contributions to the 7Ridge Fund, as well as the Company’s share of 7Ridge Fund’s profit or loss, including gains or losses arising from the fair value measurement of the investment held by the 7Ridge Fund, booked against the investment account. The carrying value of the investment is included in investments within the condensed consolidated balance sheets. The Company’s maximum loss exposure, in the unlikely event that all of the VIE’s assets become worthless, is limited to the carrying value of Company’s investment. Other Equity Investments The carrying value of other equity investments is included in investments in the condensed consolidated balance sheets. The Company accounts for these investments using the measurement alternative given the absence of readily determinable fair values for the respective investments and due to the Company’s inability to exercise significant influence over the investments based upon the respective ownership interests held. As of March 31, 2023, other equity investments primarily consist of minority investments in Eris Innovations Holdings, LLC, CSD Br, Coin Metrics Inc., Cboe Vest Financial Group, Inc, Effective Investing Limited, and a 20% investment in OCC.
