(A) Our SSN investments do not have industry concentrations and as such have been separated in the tables above.
(B) Equity, unless specifically stated otherwise, includes our investments in preferred stock, common stock, membership interests, net profits interests, net operating income interests, net revenue interests, overriding royalty interests, escrows receivable, and warrants.
[3] The terms “Prospect,” “the Company,” “we,” “us” and “our” mean Prospect Capital Corporation and its subsidiaries unless the context specifically requires otherwise. The securities in which Prospect has invested were acquired in transactions that were exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”). These securities may be resold only in transactions that are exempt from registration under the Securities Act.
[4] CP Holdings of Delaware LLC (“CP Holdings”), a consolidated entity in which we own 100% of the membership interests, owns 99.8% of CP Energy Services Inc. (“CP Energy”) as of September 30, 2022 and June 30, 2022. CP Energy owns directly or indirectly 100% of each of CP Well Testing, LLC; Wright Foster Disposals, LLC; Foster Testing Co., Inc.; ProHaul Transports, LLC; and Wright Trucking, Inc. We report CP Energy as a separate controlled company. In June 2019, CP Energy purchased a controlling interest in the common equity of Spartan Energy Holdings, Inc. (“Spartan Holdings”), which owns 100% of Spartan Energy Services, LLC (“Spartan”), a portfolio company of Prospect with $27,347 in first lien term loans (the “Spartan Term Loans”) due to us as of September 30, 2022. As a result of CP Energy’s purchase, and given Prospect’s controlling interest in CP Energy, our Spartan Term Loans are presented as control investments under CP Energy. Spartan remains the direct borrower and guarantor to Prospect for the Spartan Term Loans. In September 2020, we made a new $26,193 Series A preferred stock investment in Spartan Energy Holdings, Inc., which equates to 100% of the Series A non-voting non-convertible preferred stock outstanding. In September 2020, Spartan Energy Services, LLC fully repaid the $26,193 Senior Secured Term Loan B receivable to us at par. We recorded a realized gain of $2,832 in our Consolidated Statement of Operations for the quarter ended September 30, 2020 as a result of this transaction.
[5] As defined in the 1940 Act, we are deemed to “Control” these portfolio companies because we own more than 25% of the portfolio company’s outstanding voting securities. Transactions during the three months ended September 30, 2022 with these controlled investments were as follows:

[7] The interest rate on these investments, excluding those on non-accrual, contains a paid in kind (“PIK”) provision, whereby the issuer has either the option or the obligation to make interest payments with the issuance of additional securities.

[9] Syndicated investment which was originated by a financial institution and broadly distributed.
[10] 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 values of the investments held by PCF at September 30, 2022 and June 30, 2022 were $2,658,423 and $2,638,042, respectively, representing 35.1% and 34.7% of our total investments, respectively.
[11] 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 of September 30, 2022 and June 30, 2022, our qualifying assets, as a percentage of total assets, stood at 81.06% and 80.64%, respectively. We monitor the status of these assets on an ongoing basis.
[12] 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.
[13] 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 September 30, 2022 and June 30, 2022, we had $43,434 and $43,934, respectively, of undrawn revolver and delayed draw term loan commitments to our portfolio companies.
[14] This investment represents a Level 2 security in the ASC 820 table as of September 30, 2022. See Notes 2 and 3 within the accompanying notes to consolidated financial statements for further discussion.
[15] 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.
[16] Represents non-income producing security that has not paid a dividend in the year preceding the reporting date.
