(J) On March 28, 2023, the USES Corp. First Lien Equipment Term Loan was amended to allow interest accruing in cash to be payable in kind resulting in a maximum current PIK rate of 14.36%.
[6] Security, or a portion thereof, is held by Prospect Capital Funding LLC (“PCF”), our wholly owned subsidiary and a bankruptcy remote special purpose entity, and is pledged as collateral for the Revolving Credit Facility and such security is not available as collateral to our general creditors (see Note 4). The fair value of the investments held by PCF at June 30, 2024 and June 30, 2023 were $2,793,051 and $3,051,668, respectively, representing 36.2% and 39.5% of our total investments, respectively.
[7] 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 and June 30, 2023, our qualifying assets, as a percentage of total assets, stood at 83.78% and 82.08%, respectively. We monitor the status of these assets on an ongoing basis.
[8] 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.
[9] The effective yield has been estimated to be 0% as expected future cash flows are anticipated to not be sufficient to repay the investment at cost. If the expected investment proceeds increase, there is a potential for future investment income from the investment. Distributions, once received, will be recognized as return of capital, and when called, any remaining unamortized investment costs will be written off if the actual distributions are less than the amortized investment cost. To the extent that the cost basis of the SSN is fully recovered, any future distributions will be recorded as realized gains.
[10] Undrawn committed revolvers and delayed draw term loans to our portfolio companies incur commitment and unused fees ranging from 0.00% to 7.25%. As of June 30, 2024 and June 30, 2023, we had $34,771 and $47,875, respectively, of undrawn revolver and delayed draw term loan commitments to our portfolio companies.

[12] The terms “Prospect,” “the Company,” “we,” “us” and “our” mean Prospect Capital Corporation and its subsidiaries unless the context specifically requires otherwise.

These securities may be resold only in transactions that are exempt from registration under the Securities Act.
[13] The Company has entered into an intercreditor agreement that entitles the Company to the “last out” tranche of the first lien secured loans, whereby the “first out” tranche will receive priority as to the “last out” tranche(s) with respect to payments of principal, interest, and any other amounts due thereunder. Therefore, the Company may receive a higher interest rate than the “first out” lenders and the Consolidated Schedule of Investments above reflects such higher rate, as applicable.
