We are subject to financial market risks, including valuation risk and changes in interest rates.
Valuation Risk. Most of our investments will not have a readily available market price. To ensure accurate valuations, our investments are valued at fair value in good faith by the Investment Adviser, as our Valuation Designee, subject to the oversight of our Board based on, among other things, the input of independent third-party valuation firms engaged at the direction of the Valuation Designee, and in accordance with our valuation policy. There is no single standard for determining fair value. As a result, determining fair value requires that judgment be applied to the specific facts and circumstances of each investment while employing a consistently applied valuation process for the investments we hold. Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of our investments could fluctuate from period to period, if we were required to liquidate a portfolio investment in a forced or liquidation sale, we could realize significantly less than the value at which we have recorded it.
Interest Rate Risk. Many of the loans in our portfolio have floating interest rates, and we expect that our loans in the future could also have floating interest rates. These loans are usually based on floating SOFR or another base rate and typically have interest rate reset provisions that adjust applicable interest rates under such loans to current market rates on a daily, monthly, quarterly, semi-annual, or annual basis. The loans that are subject to floating SOFR or another base rate are also typically subject to a minimum base rate, or floor, that we charge on our loans if the current market rates are below the respective floors. As of June 30, 2026 and September 30, 2025, the weighted average floor on loans subject to floating interest rates was 0.76% and 0.78%, respectively. The Class A-1R, and A-2RR 2024 Notes issued in connection with the 2024 Debt Securitization have floating rate interest provisions based on three-month SOFR plus a spread adjustment. The JPM Credit Facility has a floating interest rate provision that, as of June 30, 2026, is primarily based on an applicable base rate (as defined in Note 7 to our consolidated financial statements) plus a spread that ranges from 1.525% to 1.775% plus a spread adjustment of 0.10% on SOFR borrowings. The Adviser Revolver has a floating interest rate provision equal to the mid-term Applicable Federal Rate. We have entered into three interest rate swaps on the 2028 Notes and two interest rate swaps on the 2029 Notes and these swaps have floating rate provisions based on one-month SOFR plus a spread of 3.327%, one-month SOFR plus a spread of 2.835%, floating rate SOFR plus a spread of 1.723%, one-month SOFR plus a spread of 2.444%, and three-month SOFR plus a spread of 2.012%, respectively. Furthermore, we have entered into three interest rate swaps on the 2031 Notes and these swaps have floating rate provisions based on Daily SOFR plus a spread of 2.171%, Daily SOFR plus a spread of 2.203%, and Daily SOFR plus a spread of 2.185%, respectively. We expect that other credit facilities and swaps into which we enter in the future could have floating interest rate provisions.
Assuming that the unaudited interim Consolidated Statement of Financial Condition as of June 30, 2026 was to remain constant and that we took no actions to alter interest rate sensitivity as of such date, the following table shows the annualized impact of hypothetical base rate changes in interest rates.

Although we believe that this analysis is indicative of our sensitivity to interest rate changes as of June 30, 2026, it does not adjust for changes in the credit market, credit quality, the size and composition of the assets in our portfolio and other business developments, including borrowings under the Debt Securitizations, the JPM Credit Facility, the

Adviser Revolver, or other borrowings, that could affect net increase in net assets resulting from operations, or net income. Accordingly, we can offer no assurances that actual results would not differ materially from the analysis above.
We have and, in the future, could hedge against interest rate fluctuations by using standard hedging instruments such as interest rate swaps, futures, options and forward contracts to the limited extent permitted under the 1940 Act and applicable commodities laws. While hedging activities could insulate us against adverse changes in interest rates, they could also limit our ability to participate in the benefits of lower interest rates with respect to the investments in our portfolio with fixed interest rates.
