Debt Disclosure [Abstract] |
BORROWINGS | BORROWINGS In accordance with the 1940 Act, effective April 25, 2019, the Company is only allowed to borrow amounts such that its asset coverage (i.e., the ratio of assets less liabilities not represented by senior securities to senior securities such as borrowings), calculated pursuant to the 1940 Act, is at least 150% after such borrowing. The Board of Directors also approved a resolution that limits the Company’s issuance of senior securities such that the asset coverage ratio, taking into account any such issuance, would not be less than 166%, which became effective April 25, 2019. On August 11, 2021, we received an exemptive order from SEC to permit us to exclude the senior securities issued by the SBIC Subsidiaries from the definition of senior securities in the asset coverage requirement applicable to the Company under the 1940 Act. As of September 30, 2025, the Company’s asset coverage was 208%. The Company had the following borrowings outstanding as of September 30, 2025 and March 31, 2025 (amounts in thousands):

(1)The unamortized debt issuance costs for the Corporate Credit Facility and the SPV Credit Facility are reflected as "Debt issuance costs" on the Consolidated Statements of Assets and Liabilities. (2)Each estimated fair value for the SBA Debentures, the 2029 Convertible Notes and the September 2030 Notes is a Level 3 fair value measurement under ASC 820 based on a valuation model using a discounted cash flow analysis. The estimated fair value of the August 2028 Notes is based on the closing price of the security on the Nasdaq Global Select Market, which is a Level 1 input under ASC 820. The estimated fair value of the Corporate Credit Facility and the SPV Credit Facility approximates its recorded value due to its variable interest rate. The estimated fair value for the October 2026 Notes is based on a redemption price of 100% of the aggregate principal amount outstanding, as discussed below. Credit Facilities As of September 30, 2025, the Company had in place one revolving credit facility and one special purpose vehicle financing facility, the Corporate Credit Facility and the SPV Facility, respectively (each defined below and together, the "Credit Facilities"). For the three and six months ended September 30, 2025, the weighted average interest rate on the Credit Facilities was 6.79% and 6.76%, respectively, and the average debt outstanding under the Credit Facilities was $315.4 million and $317.5 million, respectively. Corporate Credit Facility In August 2016, CSWC entered into a senior secured revolving credit facility (the “Corporate Credit Facility”) to provide additional liquidity to support its investment and operational activities. On August 2, 2023, the Company entered into the Third Amended and Restated Senior Secured Revolving Credit Agreement (as amended or otherwise modified from time to time, including the Amendment (as defined below), the "Credit Agreement"). Borrowings under the Corporate Credit Facility accrue interest at a rate equal to the applicable Adjusted Term SOFR plus 2.15% per annum. The Credit Agreement (1) increased commitments under the Corporate Credit Facility from $400 million to $435 million from a diversified group of lenders; (2) added an uncommitted accordion feature that could increase the maximum commitments up to $750 million; (3) extended the end of the Corporate Credit Facility's revolving period from August 9, 2025 to August 2, 2027 and extended the final maturity from August 9, 2026 to August 2, 2028; and (4) amended several financial covenants. As of September 30, 2025, the total commitments under the Corporate Credit Facility were $510 million provided by 11 lenders. On March 1, 2024, the Company entered into Amendment No. 1 to the Credit Agreement (the "Amendment"). The Amendment amends the Credit Agreement and other related loan documents to, among other things, permit the Company to enter into special purpose vehicle financings and exclude assets held by any such special purpose vehicle from the assets pledged as collateral securing the Corporate Credit Facility. CSWC pays unused commitment fees of 0.50% to 1.00% per annum, based on utilization, on the unused lender commitments under the Corporate Credit Facility. The Corporate Credit Facility contains certain affirmative and negative covenants, including but not limited to: (1) certain reporting requirements; (2) maintaining RIC and BDC status; (3) maintaining a minimum senior coverage ratio of 2.00 to 1; (4) maintaining a minimum shareholders’ equity; (5) maintaining a minimum consolidated net worth; (6) maintaining a regulatory asset coverage of not less than 150%; and (7) maintaining an interest coverage ratio of at least 2.00 to 1. The Credit Agreement also contains customary events of default, including, without limitation, nonpayment, misrepresentation of representations and warranties in a material respect, breach of covenant, bankruptcy, and change of control, with customary cure and notice provisions. If the Company defaults on its obligations under the Credit Agreement, the lenders may have the right to foreclose upon and sell, or otherwise transfer, the collateral subject to their security interests. The Corporate Credit Facility is secured by (1) all of the present and future property and assets of the Company and the guarantors and (2) 100% of the equity interests in certain of the Company’s wholly-owned subsidiaries (except for the assets held by the SBIC Subsidiaries and SPV). As of September 30, 2025, all of the Company’s assets were pledged as collateral for the Corporate Credit Facility, except for assets held by the SBIC Subsidiaries and SPV. As of September 30, 2025 and 2024, CSWC was in compliance with all financial covenants under the Credit Agreement.

SPV Credit Facility On March 20, 2024, SPV entered into a Loan Financing and Servicing Agreement (the “Loan Agreement”) for a special purpose vehicle financing credit facility (the “SPV Credit Facility”) to provide additional liquidity to support its investment and operational activities. The SPV Credit Facility included an initial commitment of $150.0 million. Pursuant to the terms of the Loan Agreement, on June 20, 2024, total commitments automatically increased from $150.0 million to $200.0 million. The SPV Credit Facility also includes an accordion feature that allows increases up to $400 million of total commitments from new and existing lenders on the same terms and conditions as the existing commitments. Borrowings under the SPV Credit Facility bear interest at three-month Term SOFR plus 2.50% per annum during the revolving period ending on March 20, 2027 and three-month Term SOFR plus an applicable margin of 2.85% thereafter. SPV (i) paid unused commitment fees of 0.10% through April 20, 2024 and (ii) pays unused commitment fees of 0.35% thereafter, on the unused lender commitments under the SPV Credit Facility, in addition to other customary fees. Under the SPV Credit Facility, SPV also pays a utilization fee based on the amount of borrowings utilized. The SPV Credit Facility matures on March 20, 2029. The Loan Agreement contains customary terms and conditions, including affirmative and negative covenants. The Loan Agreement also contains customary events of default including, without limitation, nonpayment, misrepresentation of representations and warranties in a material respect, breach of covenant, bankruptcy, and change of control, with customary cure and notice provisions.

Unsecured Notes The unsecured notes described below are the direct unsecured obligations of the Company, rank pari passu with the Company's other outstanding and future unsecured unsubordinated indebtedness and are effectively or structurally subordinated to all of the Company's existing and future secured indebtedness, including borrowings under the Credit Facilities and the SBA Debentures. January 2026 Notes In December 2020, the Company issued $75.0 million in aggregate principal amount of 4.50% Notes due 2026 (the "Existing January 2026 Notes").

The indenture governing the August 2028 Notes contains certain covenants, including certain covenants requiring the Company to comply with Section 18(a)(1)(A) as modified by Section 61(a)(2) of the 1940 Act, or any successor provisions, whether or not the Company continues to be subject to such provisions of the 1940 Act, but giving effect, in either case, to any exemptive relief granted to the Company by the SEC, to comply with Section 18(a)(1)(B) as modified by Section 61(a)(2) of the 1940 Act, or any successor provisions, after giving effect to any exemptive relief granted to the Company by the SEC and subject to certain other exceptions, and to provide financial information to the holders of the August 2028 Notes and the trustee under the indenture if the Company is no longer subject to the reporting requirements under the Exchange Act.

The 2029 Convertible Notes bear interest at a rate of 5.125% per year, payable quarterly on February 15, May 15, August 15 and November 15 of each year. The 2029 Convertible Notes will mature on November 15, 2029, unless earlier converted, redeemed or repurchased. At any time prior to the close of business on the business day immediately preceding November 15, 2029, holders may convert all or any portion of their 2029 Convertible Notes. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of its common stock, or a combination of cash and shares of its common stock, at the Company's election. The conversion rate was initially 40.0000 shares of common stock per $1,000 principal amount of 2029 Convertible Notes (equivalent to an initial conversion price of $25.00 per share of common stock). The conversion rate is subject to adjustment upon certain events, such as share splits and combinations, mergers, tender or exchange offers, increases in dividends in excess of $0.58 per share per quarter for the 2029 Convertible Notes and certain changes in control. In no event will the total number of shares of common stock issuable upon conversion exceed 44.7828 per $1,000 principal amount of the 2029 Convertible Notes. The Company has determined that the embedded conversion option in the 2029 Convertible Notes is not required to be separately accounted for as a derivative under GAAP. In addition, following certain corporate events that occur prior to the maturity date of the 2029 Convertible Notes or if the Company delivers a notice of redemption, the Company will, in certain circumstances, increase the conversion rate for a holder who elects to convert its 2029 Convertible Notes in connection with such a corporate event or notice of redemption, as the case may be.

(1)Average borrowings for the three and six months ended September 30, 2025 were calculated from September 18, 2025 (the issuance date of the September 2030 Notes) through September 30, 2025. The indenture governing the September 2030 Notes contains certain covenants, including certain covenants requiring the Company to comply with Section 18(a)(1)(A) as modified by Section 61(a)(2) of the 1940 Act, or any successor provisions, whether or not the Company continues to be subject to such provisions of the 1940 Act, but giving effect, in either case, to any exemptive relief granted to the Company by the SEC, to comply with Section 18(a)(1)(B) as modified by Section 61(a)(2) of the 1940 Act, or any successor provisions, after giving effect to any exemptive relief granted to the Company by the SEC and subject to certain other exceptions, and to provide financial information to the holders of the September 2030 Notes and the trustee under the indenture if the Company is no longer subject to the reporting requirements under the Exchange Act. These covenants are subject to important limitations and exceptions that are described in the indenture and the seventh supplemental indenture relating to the September 2030 Notes. In addition, holders of the September 2030 Notes can require the Company to repurchase some or all of the September 2030 Notes at a purchase price equal to 100% of their principal amount, plus accrued and unpaid interest to, but not including, the repurchase date upon the occurrence of a “Change of Control Repurchase Event,” as defined in the seventh supplemental indenture relating to the September 2030 Notes. SBA Debentures On April 20, 2021 and April 17, 2025, SBIC I and SBIC II, respectively, received a license from the SBA to operate as an SBIC under Section 301(c) of the Small Business Investment Act of 1958, as amended. The licenses allow each of SBIC I and SBIC II to obtain leverage by issuing SBA Debentures, subject to the issuance of a leverage commitment by the SBA. SBA Debentures are loans issued to an SBIC that have interest payable semi-annually and a ten-year maturity. The interest rate is fixed shortly after issuance at a market-driven spread over U.S. Treasury Notes with ten-year maturities. Interest on SBA Debentures is payable semi-annually on March 1 and September 1. Current statutes and regulations permit SBIC I and SBIC II to each borrow up to $175 million in SBA Debentures with at least $87.5 million in regulatory capital (as defined in the SBA regulations). The SBA may limit the amount that may be drawn each year under these commitments, and each issuance of leverage is conditioned on SBIC I and SBIC II's full compliance, as determined by the SBA, with the terms and conditions set forth in the SBA regulations. As of September 30, 2025, SBIC I had regulatory capital of $87.5 million and leverageable capital of $87.5 million, and SBIC II had regulatory capital of $87.5 million and leveragable capital of $26.0 million. As of September 30, 2025, SBIC I had a total leverage commitment from the SBA in the amount of $175.0 million, all of which was drawn. As of September 30, 2025, SBIC II had a total leverage commitment from the SBA in the amount of $40.0 million, none of which was drawn. The summary information regarding the SBA Debentures is as follows (dollars in thousands):
