[15] As of September 30, 2023, no amounts were funded by the Company under this first lien senior secured revolving loan; however, there were letters of credit issued and outstanding through a financial intermediary under the loan. See Note 7 for further information on letters of credit commitments related to certain portfolio companies.
[16] The Company sold a participating interest of approximately $34.2 in aggregate principal amount outstanding of the portfolio company’s first lien senior secured revolving loan. As the transaction did not qualify as a “true sale” in accordance with U.S. generally accepted accounting principles (“GAAP”), the Company recorded a corresponding $34.2 secured borrowing, at fair value, included in “secured borrowings” in the accompanying consolidated balance sheet. As of September 30, 2023, the interest rate in effect for the secured borrowing was 12.93%.
[17] The Company sold a participating interest of approximately $79.0 in aggregate principal amount outstanding of the portfolio company’s first lien senior secured revolving loan. As the transaction did not qualify as a “true sale” in accordance with GAAP, the Company recorded a corresponding $79.0 secured borrowing, at fair value, included in “secured borrowings” in the accompanying consolidated balance sheet. As of December 31, 2022, the interest rate in effect for the secured borrowing was 11.62%.
[18] In addition to the interest earned based on the stated interest rate of this security, the Company is entitled to receive an additional interest amount of 2.00% on $40.5 in aggregate principal amount of a “first out” tranche of the portfolio company’s senior term debt previously syndicated by the Company into “first out” and “last out” tranches, whereby the “first out” tranche will have priority as to the “last out” tranche with respect to payments of principal, interest and any other amounts due thereunder.
[19] In addition to the interest earned based on the stated interest rate of this security, the Company is entitled to receive an additional interest amount of 2.00% on $40.9 in aggregate principal amount of a “first out” tranche of the portfolio company’s senior term debt previously syndicated by the Company into “first out” and “last out” tranches, whereby the “first out” tranche will have priority as to the “last out” tranche with respect to payments of principal, interest and any other amounts due thereunder.
[20] In addition to the interest earned based on the stated contractual interest rate of this security, the certificates entitle the holders thereof to receive a portion of the excess cash flow from the SDLP’s loan portfolio, after expenses, which may result in a return to the Company greater than the contractual stated interest rate.
[21] In addition to the interest earned based on the stated contractual interest rate of this security, the certificates entitle the holders thereof to receive a portion of the excess cash flow from the SDLP’s loan portfolio, after expenses, which may result in a return to the Company greater than the contractual stated interest rate.
[22] As defined in the Investment Company Act, the Company is deemed to be an “Affiliated Person” because it owns 5% or more of the portfolio company’s outstanding voting securities or it has the power to exercise control over the management or policies of such portfolio company (including through a management agreement). Transactions as of and during the year ended December 31, 2022 in which the issuer was an Affiliated Person of the Company (but not a portfolio company that the Company is deemed to Control) are as follows:
