(12)Investment has been designated as an investment not “qualifying” under Section 55(a) of the Investment Company Act of 1940 (the “1940 Act”). Under the 1940 Act, we may not acquire any non-qualifying asset unless, at the time such acquisition is made, qualifying assets represent at least 70% of our total assets as calculated in accordance with regulatory requirements. As of June 30, 2024, our qualifying assets, as a percentage of total assets, stood at 83.78%. We monitor the status of these assets on an ongoing basis.
[12] (5)This investment is in the equity class of the collateralized loan obligation (“CLO”) security, which is referred to as “Subordinated Structured Note,” or “SSN”. The SSN investments are entitled to recurring distributions which are generally equal to the excess cash flow generated from the underlying investments after payment of the contractual payments to debt holders and fund expenses. The current estimated yield, calculated using amortized cost, is based on the current projections of this excess cash flow taking into account assumptions which have been made regarding expected prepayments, losses and future reinvestment rates. These assumptions are periodically reviewed and adjusted. Ultimately, the actual yield may be higher or lower than the estimated yield if actual results differ from those used for the assumptions.

To the extent that the cost basis of the SSN is fully recovered, any future distributions will be recorded as realized gains.
