Borrowings

Note 7. Borrowings

In accordance with the 1940 Act, with certain limited exceptions, prior to February 6, 2019, the Company was allowed to borrow amounts such that its asset coverage, as defined in the 1940 Act, was at least 200% after such borrowing. On February 5, 2019, the Company’s stockholders voted to approve the asset coverage requirement decrease to 150% from 200% in accordance with Section 61(a)(2) of the 1940 Act. Effective February 6, 2019, the reduced asset coverage requirement permits the Company to have a ratio of total consolidated assets to outstanding indebtedness of 2:1 as compared to a maximum of 1:1 under the 200% asset coverage requirement. As of September 30, 2023, the Company’s asset coverage for borrowed amounts was 180.7%.

2018 Debt Securitization: On November 16, 2018, the Company completed a $602,400 term debt securitization (the “2018 Debt Securitization”). The notes offered in the 2018 Debt Securitization (the “2018 Notes”) were issued by the 2018 Issuer, a subsidiary of 2018 CLO Depositor, and are backed by a diversified portfolio of senior secured and second lien loans. The transaction was executed through a private placement of approximately $327,000 of AAA/AAA Class A 2018 Notes, which bear interest at three-month LIBOR plus 1.48%; $61,200 of AA Class B 2018 Notes, which bear interest at three-month LIBOR plus 2.10%; $20,000 of A Class C-1 2018 Notes, which bear interest at three-month LIBOR plus 2.80%; $38,800 of A Class C-2 2018 Notes, which bear interest at three-month LIBOR plus 2.65%; $42,000 of BBB- Class D 2018 Notes, which bear interest at three-month LIBOR plus 2.95%; and $113,400 of Subordinated 2018 Notes which do not bear interest. The Company indirectly retained all of the Class C-2, Class D and Subordinated 2018 Notes.

Through January 20, 2023, the 2018 Issuer was permitted to use all principal collections received on the underlying collateral to purchase new collateral under the direction of the Investment Adviser, in its capacity as collateral manager of the 2018 Issuer and in accordance with the Company’s investment strategy, allowing the Company to maintain the initial leverage in the 2018 Debt Securitization. For the year ended September 30, 2023, the Company had repayments on the 2018 Notes of $19,503.

The Company was permitted, subject to certain conditions, to request a one-time funding of the Class C 2020 Notes, which would not be deemed an additional issuance of notes, but would have caused the Class C 2020 Notes to be additional debt of the Company. As a part of the 2020 Debt Securitization, the Company also entered into a credit agreement (the “Credit Agreement”) upon closing of the transactions pursuant to which various financial institutions and other persons which were, or could have become, parties thereto as lenders (the “Lenders”) committed to make $20,000 of AAA Class A-1-L loans to the Company (the “2020 Loans”). The 2020 Loans bore interest at three-month LIBOR plus 2.35% and were fully drawn upon closing of the transactions. Any Lender could have elected to convert all or a portion of the Class A-1-L Loans held by such Lender into Class A-1 2020 Notes upon written notice to the Company in accordance to the Credit Agreement. The Class A-1 2020 Notes, the Class A-2 2020 Notes and the Class B 2020 Notes were issued through a private placement. The Class C 2020 Notes and the Subordinated 2020 Notes were retained by the Company and the Company was the sole owner of the equity of the 2020 Issuer.

On August 26, 2021, the 2020 Issuer redeemed the outstanding 2020 Notes pursuant to the terms of the indenture governing such 2020 Notes. Following such redemption, the agreements that governed the 2020 Debt Securitization were terminated. The 2020 Notes would have otherwise matured on November 5, 2032. The pool of loans in the 2020 Debt Securitization was required to meet certain requirements, including asset mix and concentration, collateral coverage, term, agency rating, minimum coupon, minimum spread and sector diversity requirements.

The Investment Adviser served as collateral manager to the 2020 Issuer and serves as the collateral manager to the 2018 Issuer and GCIC 2018 Issuer under separate collateral management agreements and receives a fee for providing these services.

SBA Debentures: On November 4, 2020, May 4, 2021 and September 21, 2021, SBIC IV, SBIC V, and SBIC VI, respectively, surrendered their licenses to operate as a SBIC. The SBICs were subject to a variety of regulations and

oversight by the SBA concerning the size and nature of the companies in which they invested as well as the

structures of those investments. The licenses allowed the SBICs to obtain leverage by issuing SBA-guaranteed

debentures, subject to issuance of a capital commitment by the SBA and customary procedures. These debentures

were non-recourse to the Company, had interest payable semiannually and a ten-year maturity. The interest rate was

fixed at the time of issuance at a market-driven spread over U.S. Treasury Notes with ten-year maturities.

As of September 30, 2023 and September 30, 2022, each of SBIC IV, SBIC V and SBIC VI had no outstanding SBA-guaranteed debentures. The original amount of debentures committed to SBIC IV, SBIC V and SBIC VI by the SBA were $150,000, $175,000 and $175,000, respectively.

The JPM Credit Facility provides for the issuance of letters of credit in an initial aggregate face amount of up to $23,750, subject to increase or reduction from time to time pursuant to the terms of the JPM Credit Facility.

The JPM Credit Facility is secured by a first priority security interest in substantially all of the assets of the Company and certain of the Company’s subsidiaries thereunder.

Borrowings under the JPM Credit Facility bear interest at the applicable base rate plus a margin of either 1.75% or 1.875%, subject to compliance with a borrowing base test. The applicable base rate under the JPM Credit Facility is (i) one-month SOFR with respect to any advances denominated in U.S. dollars, (ii) SONIA with respect to any advances denominated in U.K. pound sterling, (iii) one-month EURIBOR with respect to any advances denominated in euros, and (iv) the relevant rate as defined in the JPM Credit Facility for borrowings in other currencies. Effective September 13, 2022, interest under the JPM Facility for loans denominated in SOFR were converted to reference a benchmark rate of term SOFR plus an adjustment of an amount ranging between 0.11448% and 0.42826% (subject to applicable tenor). Effective March 17, 2023, the adjustment to term SOFR was reduced to 0.10%.

The Company pays a commitment fee of 0.375% per annum on the daily unused portion of commitments under the JPM Credit Facility. The Company is also required to pay letter of credit participation fees and a fronting fee on the daily amount of any lender’s exposure with respect to any letters of credit issued at the request of the Company under the JPM Credit Facility.
