[1] All debt investments are income producing unless otherwise noted. All equity investments are non-income producing unless otherwise noted.
[2] Each of the Company's investments is pledged as collateral under one or more of its credit facilities. A single investment may be divided into parts that are individually pledged as collateral to separate credit facilities.
[3] Equity ownership may be held in shares or units of companies related to the portfolio companies.
[4] See Note 3 in the accompanying notes to the Consolidated Financial Statements for portfolio composition by geographic region.
[5] As defined in the Investment Company Act, the Company is deemed to be both an "Affiliated Person" of and to "Control" these portfolio companies as the Company owns more than 25% of the portfolio company's outstanding voting securities or has the power to exercise control over management or policies of such portfolio company (including through a management agreement). See Schedule 12-14 in the accompanying notes to the Consolidated Financial Statements for transactions during the year ended September 30, 2022 in which the issuer was both an Affiliated Person and a portfolio company that the Company is deemed to control.
[6] Control Investments generally are defined by the Investment Company Act as investments in companies in which the Company owns more than 25% of the voting securities or maintains greater than 50% of the board representation.
[7] As defined in the Investment Company Act, the Company is deemed to be both an "Affiliated Person" of and to "Control" these portfolio companies as the Company owns more than 25% of the portfolio company's outstanding voting securities or has the power to exercise control over management or policies of such portfolio company (including through a management agreement). See Schedule 12-14 in the accompanying notes to the Consolidated Financial Statements for transactions during the year ended September 30, 2023 in which the issuer was both an Affiliated Person and a portfolio company that the Company is deemed to control.
[8] Control Investments generally are defined by the Investment Company Act of 1940, as amended (the "Investment Company Act"), as investments in companies in which the Company owns more than 25% of the voting securities or maintains greater than 50% of the board representation.
[9] Affiliate Investments generally are defined by the Investment Company Act as investments in companies in which the Company owns between 5% and 25% of the voting securities.
[10] Affiliate Investments generally are defined by the Investment Company Act as investments in companies in which the Company owns between 5% and 25% of the voting securities.

[13] As of September 30, 2023, these investments were categorized as Level 3 within the fair value hierarchy established by Financial Accounting Standards Board ("FASB") guidance under Accounting Standards Codification ("ASC") Topic 820, Fair Value Measurements and Disclosures ("ASC 820").
[14] Interest rates may be adjusted from period to period on certain term loans and revolvers. These rate adjustments may be either temporary in nature due to tier pricing arrangements or financial or payment covenant violations in the original credit agreements or permanent in nature per loan amendment or waiver documents.
[15] Investment had undrawn commitments. Unamortized fees are classified as unearned income which reduces cost basis, which may result in a negative cost basis. A negative fair value may result from the unfunded commitment being valued below par.
[16] The interest rate on the principal balance outstanding for most of the floating rate loans is indexed to the secured overnight financing rate ("SOFR"), the London Interbank Offered Rate ("LIBOR" or "L"), the sterling overnight index average ("SONIA") and/or an alternate base rate (e.g., prime rate), which typically resets semi-annually, quarterly, or monthly at the borrower's option. The borrower may also elect to have multiple interest reset periods for each loan. For each of these loans, the Company has provided the applicable margin over the reference rate based on each respective credit agreement and the cash interest rate as of period end. All LIBOR and SOFR shown above is in U.S. dollars unless otherwise noted. As of September 30, 2023, the reference rates for the Company's variable rate loans were the 30-day SOFR at 5.32%, the 90-day SOFR at 5.39%, the 180-day SOFR at 5.47%, the 30-day LIBOR at 5.43%, the 90-day LIBOR at 5.65%, the 180-day LIBOR at 5.90%, the PRIME at 8.50%, the SONIA at 5.19%, the 30-day EURIBOR at 3.42%, the 90-day EURIBOR at 3.82% and the 180-day EURIBOR at 3.95%. Most loans include an interest floor, which generally ranges from 0% to 2.75%. SOFR and SONIA based contracts may include a credit spread adjustment that is charged in addition to the base rate and the stated spread.
[17] This investment represents a participation interest in the underlying securities shown.
[18] Principal includes accumulated payment in kind ("PIK") interest and is net of repayments, if any. “£” signifies the investment is denominated in British Pounds. "€" signifies the investment is denominated in Euros. All other investments are denominated in U.S. dollars.
