[16] This investment is treated as a non-qualifying investment under Section 55(a) of the 1940 Act. Under the 1940 Act, the Company may not acquire any non-qualifying asset unless, at the time the acquisition is made, qualifying assets represent at least 70% of the Company’s total assets.

[18] The Company restructured its investments in HFZ Capital Group LLC (“HFZ”) and HFZ Member RB portfolio, LLC (“Member RB”) during 2021. As part of the restructuring of HFZ, the Company obtained a 15.9% equity interest in MC Asset Management (Corporate), LLC (“Corporate”). As part of the Member RB restructuring, the Company exchanged its loan in Member RB for a promissory note in MC Asset Management (Industrial), LLC (“Industrial”). Corporate owns 100% of the equity of Industrial. In conjunction with these restructurings, the Company participated $4,758 of principal of its loan to HFZ as an equity contribution to Industrial. This participation did not qualify for sale accounting under ASC Topic 860–Transfers and Servicing because the sale did not meet the definition of a “participating interest”, as defined in the guidance, in order for sale treatment to be allowed. As a result, the Company continues to reflect its full investment in HFZ but has split the loan into two investments. The Company has recorded a portion of the contractual interest based on expected future cash flows.
