| Security Preemptive and Other Rights [Text Block] |
SEC Exemptive Order On November 14, 2025, Rand, RCM and certain of RCM’s affiliates were granted a new order for exemptive relief (the “Order”) by the SEC that superseded all prior co-investment exemptive relief orders issued to Rand and its affiliates by the SEC. The Order permits Rand to co-invest in portfolio companies with certain of RCM’s affiliates if such co-investments are done on the same terms and at the same time, as further detailed in the Order and without the need to obtain Board approval. The Order requires that a “required majority” (as defined in Section 57(o) of the 1940 Act) of the Board make certain findings (1) in most instances when Rand co-invests with RCM’s affiliates in an issuer where RCM’s affiliates have an existing investment in the issuer, and (2) if Rand disposes of an investment acquired in a co-investment transaction unless the disposition is done on a pro rata basis. Pursuant to the Order, the Board oversees Rand’s participation in the co-investment program. As required by the Order, Rand has adopted policies and procedures reasonably designed to ensure compliance with the terms of the Order, and RCM’s and Rand’s Chief Compliance Officer will provide reporting to the Board regarding compliance with such policies and procedures. |
