Borrowings Borrowings
In accordance with the 1940 Act, with certain limitations, the Company is allowed to borrow amounts such that its asset coverage, as defined in the 1940 Act, is at least 150% after such borrowing. As of September 30, 2023 and December 31, 2022, the Company’s asset coverage was 235.5% and 247.4%.
SPV Financing Facilities
From time to time, wholly-owned subsidiaries of the Company may enter into secured financing facilities (“SPV Financing Facilities”), as described below. The obligations of each special purpose vehicle (“SPV”) to the lenders are secured by a first priority security interest in all of the SPV’s portfolio investments and cash. The obligations of each SPV under the applicable SPV Financing Facility are non-recourse to the Company, and the Company’s exposure to the credit facility is limited to the value of its investment in the SPV, except for the HLEND C Fund Facility. For the HLEND C Funding Facility, the Company has agreed to provide a limited guaranty of a portion of amounts owed under the HLEND C Fund Facility in the event of certain bad acts, including fraud and certain other willful and intentional breaches of the facility documents.
In connection with the SPV Financing Facilities, the applicable SPV has made certain customary representations and warranties and is required to comply with various covenants, reporting requirements and other customary requirements for similar facilities. Each SPV Financing Facility contains customary events of default for similar financing transactions, including if a change of control of the applicable SPV occurs. Upon the occurrence and during the continuation of an event of default, the lender under the SPV Financing Facility may declare the outstanding advances and all other obligations under the SPV Financing Facility immediately due and payable. The occurrence of an event of default (as described above) triggers a requirement that the SPV obtains the consent of the lenders under the SPV Financing Facility prior to entering into any sale or disposition with respect to portfolio investments.
As of September 30, 2023, the Company was in compliance with all covenants and other requirements of the Credit Facilities and the Unsecured Notes.

Short-Term Borrowings

In order to finance certain investment transactions, the Company may, from time to time, enter into repurchase agreements, whereby the Company sells to a third party an investment that it holds and concurrently enters into an agreement to repurchase the same investment at an agreed-upon price at a future date, generally not to exceed 180-days from the date it was sold (each a “Short Term Financing Transaction”).

As of September 30, 2023, the Company had no borrowings under Short Term Financing Transactions with a third party.

In accordance with ASC 860, Transfers and Servicing, the Short Term Financing Transactions meet the criteria for secured borrowings. Accordingly, the investment financed by these agreements remains on the Company’s Consolidated Statements of Assets and Liabilities as an asset, and the Company records a liability to reflect its repurchase obligation to a third party which is reported as debt on the Company’s Statements of Assets and Liabilities. The repurchase obligation is secured by the respective investment that is the subject of the repurchase agreement. Interest expense associated with the repurchase obligation is reported on the Company’s Consolidated Statements of Operations within interest expense.
