[1] Investment Fair Value was determined using significant unobservable inputs, unless otherwise noted. See Note C — Fair Value Hierarchy for Investments — Portfolio Composition for further discussion. Negative fair value is the result of the capitalized discount on the loan or the unfunded commitment being valued below par. [2] All portfolio company headquarters are based in the U.S., unless otherwise noted. [3] Investment Fair Value was determined using significant unobservable inputs, unless otherwise noted. See Note C — Fair Value Hierarchy for Investments — Portfolio Composition for further discussion.

[4] All investments are LMM (as defined below) portfolio investments, unless otherwise noted. See Note C — Fair Value Hierarchy for Investments — Portfolio Composition for a description of LMM portfolio investments. All of the Fund’s investments, unless otherwise noted, are encumbered as security for one of the Credit Facilities (as defined below). [5] “Control” investments are defined by the 1940 Act as investments in which more than 25% of the voting securities are owned or where the ability to nominate greater than 50% of the board representation is maintained. [6] “Control” investments are defined by the 1940 Act (as defined below) as investments in which more than 25% of the voting securities are owned or where the ability to nominate greater than 50% of the board representation is maintained.

[12] “Non-Control/Non-Affiliate” investments are defined by the 1940 Act as investments that are neither Control investments nor Affiliate investments. [13] Investments may have a portion, or all, of their income received from Payment-in-Kind (“PIK”) interest or dividends. PIK interest income and cumulative dividend income represent income not paid currently in cash. The difference between the Total Rate and PIK Rate represents the cash rate as of September 30, 2026. [14] Investments may have a portion, or all, of their income received from PIK interest or dividends. PIK interest income and cumulative dividend income represent income not paid currently in cash. The difference between the Total Rate and PIK Rate represents the cash rate as of December 31, 2025. [15] Non-accrual or non-income producing debt investment.

See Note C — Fair Value Hierarchy for Investments — Portfolio Composition for a description of Private Loan portfolio investments. [18] Private Loan portfolio investment. See Note C — Fair Value Hierarchy for Investments — Portfolio Composition for a description of Private Loan portfolio investments. [19] A majority of the variable rate loans in the Investment Portfolio (as defined below) bear interest at a rate that may be determined by reference to either SOFR (“SF”) or an alternate base rate (commonly based on the federal funds rate or the Prime rate (“P”)), which typically resets every one, three, or six months at the borrower’s option. SOFR based contracts may include a credit spread adjustment (the “Adjustment”) that is charged in addition to the stated spread. The Adjustment is applied when the SOFR, plus the Adjustment, exceeds the stated floor rate, as applicable. As of September 30, 2026, SOFR based contracts in the portfolio had Adjustments ranging from 0.10% to 0.26%. [20] The position is unfunded and no interest income is being earned as of September 30, 2026. The position may earn a nominal unused facility fee on committed amounts.
