Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND BASIS OF PRESENTATION	ORGANIZATION AND BASIS OF PRESENTATION References in this Quarterly Report on Form 10-Q to “we,” “our,” “us,” “CSWC,” or the “Company” refer to Capital Southwest Corporation, unless the context requires otherwise. Organization Capital Southwest Corporation is an internally managed investment company that specializes in providing customized financing to middle market companies in a broad range of investment segments located primarily in the United States. CSWC has elected to be regulated as a business development company under the 1940 Act. Our common stock currently trades on The Nasdaq Global Select Market under the ticker symbol “CSWC.” We have elected, and intend to qualify annually, to be treated for U.S. federal income tax purposes as a regulated investment company (“RIC”) under Subchapter M of the U.S. Internal Revenue Code of 1986, as amended (the “Code”). As such, we generally will not have to pay U.S. federal income tax at corporate rates on any ordinary income or capital gains that we distribute to our shareholders as dividends. To continue to maintain our RIC tax treatment, we must meet specified source-of-income and asset diversification requirements and timely distribute annually at least 90% of our net ordinary income and realized net short-term capital gains in excess of realized net long-term capital losses, if any. We may be subject to U.S. federal income tax and a 4% U.S. federal excise tax on any income that we do not timely distribute to our shareholders. Our U.S. federal income tax liability may be reduced to the extent that we make certain distributions during the following calendar year and satisfy other procedural requirements. We focus on investing in companies with histories of generating revenues and positive cash flow, established market positions and proven management teams with strong operating discipline. Our core business is to target senior debt investments and equity investments in lower middle market (“LMM”) companies. We also opportunistically target first and second lien loans in upper middle market (“UMM”) companies. Our target LMM companies typically have annual earnings before interest, taxes, depreciation and amortization (“EBITDA”) generally between $3.0 million and $20.0 million, and our LMM investments generally range in size from $5.0 million to $35.0 million. Our UMM investments generally include first and second lien loans in companies with EBITDA generally greater than $20.0 million and our UMM investments typically range in size from $5.0 million to $20.0 million. We make available significant managerial assistance to the companies in which we invest as we believe that providing managerial assistance to an investee company is critical to its business development activities. CSWC has a direct wholly-owned subsidiary that has been elected to be a taxable entity (the “Taxable Subsidiary”). The primary purpose of the Taxable Subsidiary is to permit CSWC to hold certain interests in portfolio companies that are organized as limited liability companies, or LLCs (or other forms of pass-through entities), and still allow us to satisfy the RIC tax requirement that at least 90% of our gross income for U.S. federal income tax purposes must consist of qualifying investment income. The Taxable Subsidiary is taxed at normal corporate tax rates based on its taxable income. On April 20, 2021, our wholly owned subsidiary, Capital Southwest SBIC I, LP (“SBIC I”), received a license from the U.S. Small Business Administration (the “SBA”) to operate as a small business investment company ("SBIC") under Section 301(c) of the Small Business Investment Act of 1958, as amended. SBIC I has an investment strategy substantially similar to ours and makes similar types of investments in accordance with SBA regulations. SBIC I and its general partner are consolidated for financial reporting purposes under generally accepted accounting principles in the United States ("U.S. GAAP"), and the portfolio investments held by it are included in the consolidated financial statements. Basis of Presentation The consolidated financial statements have been prepared in accordance with U.S. GAAP. We meet the definition of an investment company and follow the accounting and reporting guidance in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946, Financial Services – Investment Companies (“ASC 946”). Under rules and regulations applicable to investment companies, we are generally precluded from consolidating any entity other than another investment company, subject to certain exceptions. One of the exceptions to this general principle occurs if the investment company has an investment in an operating company that provides services to the investment company. Accordingly, the consolidated financial statements include the Taxable Subsidiary and SBIC I. Portfolio Investment Classification We classify our investments in accordance with the requirements of the 1940 Act. Under the 1940 Act, “Control Investments” are generally defined as investments in which we own more than 25% of the voting securities; “Affiliate Investments” are generally defined as investments in which we own between 5% and 25% of the voting securities, and the investments are not classified as “Control Investments”; and “Non-Control/Non-Affiliate Investments” are generally defined as investments that are neither “Control Investments” nor “Affiliate Investments.” Under the 1940 Act, a BDC must meet certain requirements, including investing at least 70% of its total assets in qualifying assets. As of September 30, 2023, the Company has 85.1% of its total assets (at fair value) in qualifying assets. The principal categories of qualifying assets relevant to our business are: (1) securities purchased in transactions not involving any public offering from the issuer of such securities, which issuer (subject to certain limited exceptions) is an "eligible portfolio company," or from any person who is, or has been during the preceding 13 months, an affiliated person of an eligible portfolio company, or from any other person, subject to such rules as may be prescribed by the Securities and Exchange Commission ("SEC"); (2) securities of any eligible portfolio company that we control; (3) securities purchased in a private transaction from a U.S. issuer that is not an investment company or from an affiliated person of the issuer, or in transactions incident thereto, if the issuer is in bankruptcy and subject to reorganization or if the issuer, immediately prior to the purchase of its securities was unable to meet its obligations as they came due without material assistance other than conventional lending or financing arrangements; (4) securities of an eligible portfolio company purchased from any person in a private transaction if there is no readily available market for such securities and we already own 60% of the outstanding equity of the eligible portfolio company; (5) securities received in exchange for or distributed on or with respect to securities described in (1) through (4) above, or pursuant to the exercise of warrants or rights relating to such securities; and (6) cash, cash equivalents, U.S. government securities or high-quality debt securities maturing in one year or less from the time of investment. Additionally, in order to qualify for RIC tax treatment for U.S. federal income tax purposes, we must, among other things meet the following requirements: (1) continue to maintain our election as a BDC under the 1940 Act at all times during each taxable year; (2) derive in each taxable year at least 90% of our gross income from dividends, interest, payments with respect to certain securities, loans, gains from the sale of stock or other securities, net income from certain "qualified publicly traded partnerships," or other income derived with respect to our business of investing in such stock or securities; and (3) diversify our holdings in accordance with two diversification requirements: (a) diversify our holdings such that at the end of each quarter of the taxable year at least 50% of the value of our assets consists of cash, cash equivalents, U.S. Government securities, securities of other RICs, and such other securities if such other securities of any one issuer do not represent more than 5% of the value of our assets or more than 10% of the outstanding voting securities of the issuer; and (b) diversify our holdings such that no more than 25% of the value of our assets is invested in the securities, other than U.S. government securities or securities of other RICs, (i) of one issuer, (ii) of two or more issuers that are controlled, as determined under applicable Code rules, by us and that are engaged in the same or similar or related trades or businesses or (iii) of certain "qualified publicly traded partnerships" (collectively, the "Diversification Requirements"); The two Diversification Requirements must be satisfied quarterly. If a RIC satisfies the Diversification Requirements for one quarter, and then, due solely to fluctuations in market value, fails to meet one of the Diversification Requirements in the next quarter, it retains RIC tax treatment. A RIC that fails to meet the Diversification Requirements as a result of a nonqualified acquisition may be subject to excess taxes unless the nonqualified acquisition is disposed of and the Diversification Requirements are satisfied within 30 days of the close of the quarter in which the Diversification Requirements are failed. For the quarter ended September 30, 2023, we satisfied all RIC requirements and have 10.8% in nonqualified assets according to measurement criteria established in Section 851(d) of the Code.

SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Sep. 30, 2023
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The following is a summary of significant accounting policies followed in the preparation of the consolidated financial statements of CSWC. Fair Value Measurements We account for substantially all of our financial instruments at fair value in accordance with ASC Topic 820, Fair Value Measurements and Disclosures (“ASC 820”). ASC 820 defines fair value, establishes a framework used to measure fair value and requires disclosures for fair value measurements, including the categorization of financial instruments into a three-level hierarchy based on the transparency of valuation inputs. ASC 820 requires disclosure of the fair value of financial instruments for which it is practical to estimate such value. We believe that the carrying amounts of our financial instruments such as cash, receivables and payables approximate the fair value of these items due to the short maturity of these instruments. This is considered a Level 1 valuation technique. The carrying value of our credit facility approximates fair value (Level 3 input). See Note 4 below for further discussion regarding the fair value measurements and hierarchy. Investments Investments are stated at fair value and are determined by the Valuation Committee as the Valuation Designee pursuant to Rule 2a-5 under the 1940 Act, subject to the oversight of our Board of Directors, as described in the Notes to the Consolidated Schedule of Investments and Notes 3 and 4 below. Investments are recorded on a trade date basis. Net Realized Gains or Losses and Net Unrealized Appreciation or Depreciation Realized gains or losses are measured by the difference between the net proceeds from the sale or redemption of an investment or a financial instrument and the cost basis of the investment or financial instrument, without regard to unrealized appreciation or depreciation previously recognized, and includes investments written-off during the period net of recoveries and realized gains or losses from in-kind redemptions. Net unrealized appreciation or depreciation reflects the net change in the fair value of the investment portfolio and financial instruments and the reclassification of any prior period unrealized appreciation or depreciation on exited investments and financial instruments to realized gains or losses. Cash and Cash Equivalents Cash and cash equivalents, which consist of cash and highly liquid investments with an original maturity of three months or less at the date of purchase, are carried at cost, which approximates fair value. Cash may be held in a money market fund from time to time, which is a Level 1 security. At September 30, 2023 and March 31, 2023, cash held in money market funds amounted to $7.1 million and $8.9 million, respectively. Cash and cash equivalents includes deposits at financial institutions. We deposit our cash balances in financial institutions and, at times, such balances may be in excess of the Federal Deposit Insurance Corporation (“FDIC”) insurance limits. At September 30, 2023 and March 31, 2023, cash balances totaling $21.7 million and $20.3 million, respectively, exceeded FDIC insurance limits, subjecting us to risk related to the uninsured balance. All of our cash deposits are held at large established high credit quality financial institutions and management believes that the risk of loss associated with any uninsured balances is remote. Segment Information We operate and manage our business in a singular segment. As an investment company, we invest in portfolio companies in various industries and geographic areas as discussed in Note 3. Consolidation As permitted under Regulation S-X and ASC 946, we generally do not consolidate our investment in a portfolio company other than an investment company subsidiary or a controlled operating company whose business consists of providing services to CSWC. Accordingly, we consolidate the results of the Taxable Subsidiary and SBIC I. All intercompany balances have been eliminated upon consolidation. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. We have identified investment valuation and revenue recognition as our most critical accounting estimates. Interest and Dividend Income Interest and dividend income is recorded on an accrual basis to the extent amounts are expected to be collected. Dividend income is recognized on the date dividends are declared by the portfolio company or at the point an obligation exists for the portfolio company to make a distribution. Discounts/premiums received to par on loans purchased are capitalized and accreted or amortized into income over the life of the loan using the effective interest method. In accordance with our valuation policy, accrued interest and dividend income is evaluated quarterly for collectability. When we do not expect the debtor to be able to service all of its debt or other obligations, we generally will establish a reserve against interest income receivable, thereby placing the loan or debt security on non-accrual status, and cease to recognize interest income on that loan or debt security until the borrower has demonstrated the ability and intent to pay contractual amounts due. If a loan or debt security’s status significantly improves regarding its ability to service debt or other obligations, it will be restored to accrual basis. As of September 30, 2023, investments on non-accrual status represented approximately 2.0% of our total investment portfolio's fair value and approximately 2.9% of its cost. As of March 31, 2023, investments on non-accrual status represented approximately 0.3% of our total investment portfolio's fair value and approximately 1.3% of its cost. To maintain RIC tax treatment, non-cash sources of income, such as accretion of interest income, may need to be paid out to shareholders in the form of distributions, even though CSWC may not have collected the interest income. For the three months ended September 30, 2023 and 2022, approximately 3.4% and 3.6%, respectively, of CSWC's total investment income was attributable to non-cash interest income for the accretion of discounts associated with debt investments, net of any premium reduction. For the six months ended September 30, 2023 and 2022, approximately 3.2% and 3.7%, respectively, of CSWC's total investment income was attributable to non-cash interest income for the accretion of discounts associated with debt investments, net of any premium reduction. Payment-in-Kind Interest The Company currently holds, and expects to hold in the future, some investments in its portfolio that contain PIK interest provisions. The PIK interest, computed at the contractual rate specified in each loan agreement, is added to the principal balance of the loan, rather than being paid to the Company in cash, and is recorded as interest income. Thus, the actual collection of PIK interest may be deferred until the time of debt principal repayment. PIK interest, which is a non-cash source of income, is included in the Company’s taxable income and therefore affects the amount the Company is required to distribute to shareholders to maintain its qualification as a RIC for U.S. federal income tax purposes, even though the Company has not yet collected the cash. Generally, when current cash interest and/or principal payments on a loan become past due, or if the Company otherwise does not expect the borrower to be able to service its debt and other obligations, the Company will place the investment on non-accrual status and will generally cease recognizing PIK interest income on that loan for financial reporting purposes until all principal and interest have been brought current through payment or due to a restructuring such that the interest income is deemed to be collectible. The Company writes off any accrued and uncollected PIK interest when it is determined that the PIK interest is no longer collectible. As of September 30, 2023 and 2022, we have not written off any accrued and uncollected PIK interest from prior periods. For the three and six months ended September 30, 2023, we had four investments for which we stopped accruing PIK interest. For the year ended March 31, 2023, we had three investments for which we stopped accruing PIK interest. For the three months ended September 30, 2023 and 2022, approximately 3.6% and 5.2%, respectively, of CSWC’s total investment income was attributable to non-cash PIK interest income. For the six months ended September 30, 2023 and 2022, approximately 3.8% and 4.2%, respectively, of CSWC’s total investment income was attributable to non-cash PIK interest income. Fee Income Fee income, generally collected in advance, includes fees for administration and valuation services rendered by the Company. These fees are typically charged annually and are amortized into income over the year. The Company recognizes nonrecurring fees, including prepayment penalties, waiver fees and amendment fees, as fee income when earned. In addition, the Company also may be entitled to an exit fee that is amortized into income over the life of the loan. Loan exit fees to be paid at the termination of the loan are accreted into fee income over the contractual life of the loan. Warrants In connection with the Company's debt investments, the Company may receive warrants or other equity-related securities from the borrower. The Company determines the cost basis of warrants based upon their respective fair values on the date of receipt in proportion to the total fair value of the debt and warrants received. Any resulting difference between the face amount of the debt and its recorded fair value resulting from the assignment of value to the warrants is treated as original issue discount (“OID”), and accreted into interest income using the effective interest method over the term of the debt investment. Debt Issuance Costs Debt issuance costs include commitment fees and other costs related to CSWC’s senior secured revolving credit facility, its unsecured notes (as discussed further in Note 5) and the debentures guaranteed by the SBA (the "SBA Debentures"). The costs in connection with the credit facility have been capitalized and are amortized into interest expense over the term of the credit facility. The costs in connection with the unsecured notes and the SBA Debentures are a direct deduction from the related debt liability and amortized into interest expense over the term of the January 2026 Notes (as defined below), the October 2026 Notes (as defined below), the August 2028 Notes (as defined below) and the SBA Debentures. Deferred Offering Costs Deferred offering costs include registration expenses related to our shelf registration statement and expenses related to the launch of the "at-the-market" program through which we can sell, from time to time, shares of our common stock (the "Equity ATM Program"). These expenses consist primarily of SEC registration fees, legal fees and accounting fees incurred related thereto. These expenses are included in other assets on the Consolidated Statements of Assets and Liabilities. Upon the completion of an equity offering or a debt offering, the deferred expenses are charged to additional paid-in capital or debt issuance costs, respectively. If there are any deferred offering costs remaining at the expiration of the shelf registration statement, these deferred costs are charged to expense. Realized Losses on Extinguishment of Debt Upon the repayment of debt obligations that are deemed to be extinguishments, the difference between the principal amount due at maturity adjusted for any unamortized debt issuance costs is recognized as a loss (i.e., the unamortized debt issuance costs and any "make-whole" premium payment (as discussed in Note 5)) are recognized as a loss upon extinguishment of the underlying debt obligation). Leases The Company is obligated under an operating lease pursuant to which it is leasing an office facility from a third party with a remaining term of approximately 9 years. The operating lease is included as an operating lease right-of-use ("ROU") asset and operating lease liability in the accompanying Consolidated Statements of Assets and Liabilities. The Company does not have any financing leases. The ROU asset represents the Company’s right to use an underlying asset for the lease term and the operating lease liability represents the Company’s obligation to make lease payments arising from such lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the remaining lease term. The Company’s lease does not provide an implicit discount rate, and as such the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of the remaining lease payments. Lease expense is recognized on a straight-line basis over the remaining lease term. Federal Income Taxes CSWC has elected, and intends to qualify annually, to be treated for U.S. federal income tax purposes as a RIC under Subsection M of the Code. By meeting these requirements, we will not be subject to U.S. federal income taxes at corporate rates on ordinary income or capital gains timely distributed to shareholders. In order to qualify as a RIC, the Company is required to timely distribute to its shareholders at least 90% of investment company taxable income, as defined by the Code, each year. Investment company taxable income generally differs from net income for financial reporting purposes due to temporary and permanent differences in the recognition of income and expenses. Investment company taxable income generally excludes net unrealized appreciation or depreciation, as investment gains and losses are not included in investment company taxable income until they are realized. Depending on the level of taxable income or capital gains earned in a tax year, we may choose to carry forward taxable income or capital gains in excess of current year distributions into the next year and pay a 4% U.S. federal excise tax on such income. Any such carryover taxable income or capital gains must be distributed through a dividend declared on or prior to the later of (1) the filing of the U.S. federal income tax return for the applicable fiscal year and (2) the fifteenth day of the ninth month following the close of the year in which such taxable income was generated. In lieu of distributing our net capital gains for a year, we may decide to retain some or all of our net capital gains. We will be required to pay a 21% corporate rate U.S. federal income tax on any such retained net capital gains. We may elect to treat such retained capital gain as a deemed distribution to shareholders. Under such circumstances, shareholders will be required to include their share of such retained capital gain in income, but will receive a credit for the amount of U.S. federal income tax paid at corporate rates with respect to their shares. As an investment company that qualifies as a RIC, federal income taxes payable on security gains that we elect to retain are accrued only on the last day of our tax year, December 31. Any net capital gains actually distributed to shareholders and properly reported by us as capital gain dividends are generally taxable to the shareholders as long-term capital gains. See Note 6 for further discussion. The Taxable Subsidiary, a wholly-owned subsidiary of CSWC, is not a RIC and is required to pay taxes at the corporate rate of 21%. For tax purposes, the Taxable Subsidiary has elected to be treated as a taxable entity, and therefore is not consolidated for tax purposes and is taxed at normal corporate tax rates based on taxable income and, as a result of its activities, may generate an income tax provision or benefit. The taxable income, or loss, of the Taxable Subsidiary may differ from its book income, or loss, due to temporary book and tax timing differences and permanent differences. This income tax provision, or benefit, if any, and the related tax assets and liabilities, are reflected in our consolidated financial statements. Management evaluates tax positions taken or expected to be taken in the course of preparing the Company’s consolidated financial statements to determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax positions with respect to tax at the CSWC level not deemed to meet the “more-likely-than-not” threshold would be recorded as an expense in the current year. Management’s conclusions regarding tax positions will be subject to review and may be adjusted at a later date based on factors including, but not limited to, on-going analyses of tax laws, regulations and interpretations thereof. The Company has concluded that it does not have any uncertain tax positions that meet the recognition of measurement criteria of ASC Topic 740, Income Taxes , ("ASC 740") for the current period. Also, we account for interest and, if applicable, penalties for any uncertain tax positions as a component of income tax provision. No interest or penalties expense was recorded during the three and six months ended September 30, 2023 and 2022. Deferred Taxes Deferred tax assets and liabilities are recorded for losses or income at the Taxable Subsidiary using statutory tax rates. A valuation allowance is provided against deferred tax assets when it is more likely than not that some portion or all of the deferred tax asset will not be realized. ASC 740 requires the effects of changes in tax rates and laws on deferred tax balances to be recognized in the period in which the legislation was enacted. See Note 6 for further discussion. Stock-Based Compensation We account for our share-based compensation using the fair value method, as prescribed by ASC Topic 718, Compensation – Stock Compensation . Accordingly, we recognize share-based compensation cost on a straight-line basis for all share-based payments awards granted to employees. For restricted stock awards, we measure the fair value based upon the market price of our common stock on the date of the grant. For restricted stock awards, we amortize this fair value to share-based compensation expense over the vesting term. We recognize forfeitures as they occur. The unvested shares of restricted stock awarded pursuant to CSWC’s equity compensation plans are participating securities and are included in the basic and diluted earnings per share calculation. The right to grant restricted stock awards under the 2010 Plan terminated on July 18, 2021, ten years after the date that the 2010 Restricted Stock Award Plan (the “2010 Plan”) was approved by the Company’s shareholders pursuant to its terms. In connection with the termination of the 2010 Plan, the Board of Directors and shareholders approved the Capital Southwest Corporation 2021 Employee Restricted Stock Award Plan (the "2021 Employee Plan"), which became effective on July 28, 2021, as part of the compensation package for its employees, the terms of which are, in all material respects, identical to the 2010 Plan. On July 19, 2021, we received an exemptive order that supersedes the prior exemptive order relating to the 2010 Plan (the “Order”) to permit the Company to (i) issue restricted stock as part of the compensation package for its employees in the 2021 Employee Plan, and (ii) withhold shares of the Company’s common stock or purchase shares of the Company’s common stock from the participants to satisfy tax withholding obligations relating to the vesting of restricted stock pursuant to the 2021 Employee Plan. In addition, the Board of Directors and shareholders approved the Capital Southwest Corporation 2021 Non-Employee Director Restricted Stock Plan (the "Non-Employee Director Plan"), which became effective on July 27, 2022, as part of the compensation package for non-employee directors of the Board of Directors. In connection therewith, on May 16, 2022, we received an exemptive order that supersedes the Order (the "Superseding Order") and covers both employees and non-employee directors of the Board of Directors. Shareholder Distributions Distributions to common shareholders are recorded on the ex-dividend date. The amount of distributions, if any, is determined by the Board of Directors each quarter and is generally based upon the earnings estimated by management. Net realized capital gains, if any, generally are distributed, although the Company may decide to retain such capital gains for investment. Presentation Presentation of certain amounts in the consolidated financial statements for the prior year comparative consolidated financial statements is updated to conform to the current period presentation. Recently Issued or Adopted Accounting Standards In June 2022, the FASB issued ASU 2022-03, “Fair Value Measurement (Topic 820) - Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions,” which was issued to (1) clarify the guidance in Topic 820, Fair Value Measurement, when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of an equity security, (2) amend a related illustrative example, and (3) introduce new disclosure requirements for equity securities subject to contractual sale restrictions that are measured at fair value in accordance with Topic 820. The new guidance is effective for interim and annual periods beginning after December 15, 2023. The Company is currently evaluating the impact of the new standard on the Company's consolidated financial statements

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	6 Months Ended
FAIR VALUE MEASUREMENTS	Sep. 30, 2023
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Investment Valuation Process Beginning as of the fiscal quarter ended June 30, 2023, pursuant to Rule 2a-5 under the 1940 Act, the Board of Directors has designated the Valuation Committee comprised of certain officers of the Company as the Valuation Designee to determine the fair value of the Company's investments that do not have readily available market quotations, subject to the oversight of the Board of Directors. The valuation process is led by the valuation team and the Valuation Committee in conjunction with the investment team. The process includes a quarterly review of each investment by our valuation team and the Valuation Committee. Valuations of each portfolio security are prepared quarterly by the valuation team using updated financial and other operational information collected from the investment team. In conjunction with the internal valuation process, the Valuation Committee also has engaged multiple independent consulting firms specializing in financial due diligence, valuation, and business advisory services to provide third-party valuation reviews and an independent range of values for selected investments, which is presented to the Valuation Committee. CSWC also uses a standard internal investment rating system in connection with its investment oversight, portfolio management, and investment valuation procedures for its debt portfolio. This system takes into account both quantitative and qualitative factors of the portfolio company and the investments held therein. There is no single standard for determining fair value in good faith, as fair value depends upon the specific circumstances of each individual investment. While management believes our valuation methodologies are appropriate and consistent with market participants, the recorded fair values of our investments may differ significantly from fair values that would have been used had an active market for the securities existed. In addition, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different than the valuations currently assigned. Fair Value Hierarchy CSWC has established and documented processes for determining the fair values of portfolio company investments on a recurring basis in accordance with the 1940 Act and ASC 820. As required by ASC 820, when the inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement in its entirety. For example, a Level 3 fair value measurement may include inputs that are observable (Levels 1 and 2) and unobservable (Level 3). Therefore, unrealized appreciation and depreciation related to such investments categorized within the Level 3 tables below may include changes in fair value that are attributable to both observable inputs (Levels 1 and 2) and unobservable inputs (Level 3). CSWC conducts reviews of fair value hierarchy classifications on a quarterly basis. We also use judgment and consider factors specific to the investment in determining the significance of an input to a fair value measurement. The three levels of valuation inputs established by ASC 820 are as follows: • Level 1: Investments whose values are based on unadjusted quoted prices in active markets for identical assets or liabilities. • Level 2: Investments whose values are based on quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. • Level 3: Investments whose values are based on unobservable inputs that are significant to the overall fair value measurement. As of September 30, 2023 and March 31, 2023, 100% of the CSWC investment portfolio consisted of privately held debt and equity instruments for which inputs falling within the categories of Level 1 and Level 2 are generally not readily available. Therefore, the Valuation Committee determines the fair value of our investments (excluding investments for which fair value is measured at net asset value ("NAV") in good faith using Level 3 inputs, pursuant to CSWC's valuation policy and procedures subject to the oversight of the Board of Directors. Investment Valuation Inputs ASC 820 defines fair value in terms of the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date excluding transaction costs. Under ASC 820, the fair value measurement also assumes that the transaction to sell an asset occurs in the principal market for the asset or, in the absence of a principal market, the most advantageous market for the asset. The principal market is the market in which the reporting entity would sell or transfer the asset with the greatest volume and level of activity for the asset. In determining the principal market for an asset or liability under ASC 820, it is assumed that the reporting entity has access to the market as of the measurement date. The Level 3 inputs to CSWC’s valuation process reflect our best estimate of the assumptions that would be used by market participants in pricing the investment in a transaction in the principal or most advantageous market for the asset. The fair value determination of each portfolio investment categorized as Level 3 required one or more of the following unobservable inputs: • financial information obtained from each portfolio company, including unaudited statements of operations and balance sheets for the most recent period available as compared to budgeted numbers; • current and projected financial condition of the portfolio company; • current and projected ability of the portfolio company to service its debt obligations; • type and amount of collateral, if any, underlying the investment; • current financial ratios (e.g., fixed charge coverage ratio, interest coverage ratio and net debt/EBITDA ratio) applicable to the investment; • current liquidity of the investment and related financial ratios (e.g., current ratio and quick ratio); • indicative dealer quotations from brokers, banks, and other market participants; • market yields on other securities of similar risk; • pending debt or capital restructuring of the portfolio company; • projected operating results of the portfolio company; • current information regarding any offers to purchase the investment; • current ability of the portfolio company to raise any additional financing as needed; • changes in the economic environment which may have a material impact on the operating results of the portfolio company; • internal occurrences that may have an impact (both positive and negative) on the operating performance of the portfolio company; • qualitative assessment of key management; • contractual rights, obligations or restrictions associated with the investment; and • other factors deemed relevant. CSWC uses several different valuation approaches depending on the security type including the Market Approach, the Income Approach, the Enterprise Value Waterfall Approach, and the NAV Valuation Method. Market Approach Market Approach is a qualitative and quantitative analysis of the aforementioned unobservable inputs. It is a combination of the Enterprise Value Waterfall Approach and Income Approach as described in detail below. For investments recently originated (within a quarterly reporting period) or where the value has not departed significantly from its cost, we generally rely on our cost basis or recent transaction price to determine the fair value, unless a material event has occurred since origination. Income Approach In valuing debt securities, CSWC typically uses an Income Approach model, which considers some or all of the factors listed above. Under the Income Approach, CSWC develops an expectation of the yield that a hypothetical market participant would require when purchasing each debt investment (the “Required Market Yield”). The Required Market Yield is calculated in a two-step process. First, using quarterly market data we estimate the current market yield of similar debt securities. Next, based on the factors described above, we modify the current market yield for each security to produce a unique Required Market Yield for each of our investments. The resulting Required Market Yield is the significant Level 3 input to the Income Approach model. If, with respect to an investment, the unobservable inputs have not fluctuated significantly from the date the investment was made or have not fluctuated significantly from CSWC’s expectations on the date the investment was made, and there have been no significant fluctuations in the market pricing for such investments, we may conclude that the Required Market Yield for that investment is equal to the stated rate on the investment. In instances where CSWC determines that the Required Market Yield is different from the stated rate on the investment, we discount the contractual cash flows on the debt instrument using the Required Market Yield in order to estimate the fair value of the debt security. In addition, under the Income Approach, CSWC also determines the appropriateness of the use of third-party broker quotes, if any, as a significant Level 3 input in determining fair value. In determining the appropriateness of the use of third-party broker quotes, CSWC evaluates the level of actual transactions used by the broker to develop the quote, whether the quote was an indicative price or binding offer, the depth and consistency of broker quotes, the source of the broker quotes, and the correlation of changes in broker quotes with underlying performance of the portfolio company and other market indices. To the extent sufficient observable inputs are available to determine fair value, CSWC may use third-party broker quotes or other independent pricing to determine the fair value of certain debt investments. Fair value measurements using the Income Approach model can be sensitive to significant changes in one or more of the inputs. A significant increase (decrease) in the Required Market Yield for a particular debt security may result in a lower (higher) fair value for that security. A significant increase (decrease) in a third-party broker quote for a particular debt security may result in a higher (lower) value for that security. Enterprise Value Waterfall Approach In valuing equity securities (including warrants), CSWC estimates fair value using an Enterprise Value Waterfall valuation model. CSWC estimates the enterprise value of a portfolio company and then allocates the enterprise value to the portfolio company’s securities in order of their relative liquidation preference. In addition, CSWC assumes that any outstanding debt or other securities that are senior to CSWC’s equity securities are required to be repaid at par. Additionally, we may estimate the fair value of non-performing debt securities using the Enterprise Value Waterfall approach as needed. To estimate the enterprise value of the portfolio company, CSWC uses a weighted valuation model based on public comparable companies, observable transactions and discounted cash flow analyses. A main input into the valuation model is a measure of the portfolio company’s financial performance, which generally is either earnings before interest, taxes, depreciation and amortization, as adjusted (“Adjusted EBITDA”) or revenues. In addition, we consider other factors, including, but not limited to: (1) offers from third parties to purchase the portfolio company; and (2) the implied value of recent investments in the equity securities of the portfolio company. For certain non-performing assets, we may utilize the liquidation or collateral value of the portfolio company's assets in our estimation of its enterprise value. The significant Level 3 inputs to the Enterprise Value Waterfall model are (1) an appropriate multiple derived from the comparable public companies and transactions, (2) discount rate assumptions used in the discounted cash flow model and (3) a measure of the portfolio company’s financial performance, which generally is either Adjusted EBITDA or revenues. Inputs can be based on historical operating results, projections of future operating results or a combination thereof. The operating results of a portfolio company may be unaudited, projected or pro forma financial information and may require adjustments for certain non-recurring items. CSWC also may consult with the portfolio company’s senior management to obtain updates on the portfolio company’s performance, including information such as industry trends, new product development, loss of customers and other operational issues. Fair value measurements using the Enterprise Value Waterfall model can be sensitive to significant changes in one or more of the inputs. A significant increase (decrease) in either the multiple, Adjusted EBITDA or revenues for a particular equity security would result in a higher (lower) fair value for that security. NAV Valuation Method Under the NAV valuation method, for an investment in an investment fund that does not have a readily determinable fair value, CSWC measures the fair value of the investment predominately based on the NAV of the investment fund as of the measurement date. However, in determining the fair value of the investment, we may consider whether adjustments to the NAV are necessary in certain circumstances, based on the analysis of any restrictions on redemption of our investment as of the measurement date, recent actual sales or redemptions of interests in the investment fund, expected future cash flows available to equity holders, or other uncertainties surrounding CSWC’s ability to realize the full NAV of its interests in the investment fund.

BORROWINGS

BORROWINGS	6 Months Ended
BORROWINGS	Sep. 30, 2023
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 SBIC I or any future SBIC subsidiary of the Company from the definition of senior securities in the asset coverage requirement applicable to the Company under the 1940 Act. As of September 30, 2023, the Company’s asset coverage was 229%. The Company had the following borrowings outstanding as of September 30, 2023 and March 31, 2023 (amounts in thousands): Outstanding Balance Unamortized Debt Issuance Costs and Debt Discount/Premium (1) Recorded Value September 30, 2023 SBA Debentures $ 130,000 $ (3,624) $ 126,376 Credit Facility 250,000 — 250,000 January 2026 Notes 140,000 (780) 139,220 October 2026 Notes 150,000 (2,367) 147,633 August 2028 Notes 71,875 (2,437) 69,438 $ 741,875 $ (9,208) $ 732,667 March 31, 2023 SBA Debentures $ 120,000 $ (3,670) $ 116,330 Credit Facility 235,000 — 235,000 January 2026 Notes 140,000 (949) 139,051 October 2026 Notes 150,000 (2,737) 147,263 $ 645,000 $ (7,356) $ 637,644 (1) The unamortized debt issuance costs for the Credit Facility are reflected as Debt issuance costs on the Consolidated Statements of Assets and Liabilities. Credit Facility In August 2016, CSWC entered into a senior secured revolving credit facility (the “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, the "Credit Agreement"). Borrowings under the 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 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 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. CSWC pays unused commitment fees of 0.50% to 1.00% per annum, based on utilization, on the unused lender commitments under the Credit Facility. The 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 Credit Facility is secured by (1) substantially all of the present and future property and assets of the Company and the guarantors and (2) 100% of the equity interests in the Company’s wholly-owned subsidiary. As of September 30, 2023, substantially all of the Company’s assets were pledged as collateral for the Credit Facility, except for assets held by SBIC I. At September 30, 2023, CSWC had $250.0 million in borrowings outstanding under the Credit Facility. CSWC recognized interest expense related to the Credit Facility, including unused commitment fees and amortization of deferred loan costs, of $4.3 million and $9.3 million for the three and six months ended September 30, 2023, respectively. For the three and six months ended September 30, 2022, CSWC recognized interest expense of $2.9 million and $4.8 million, respectively. The weighted average interest rate on the Credit Facility was 7.70% and 7.52% and for the three and six months ended September 30, 2023, respectively. For the three and six months ended September 30, 2022, the weighted average interest rate on the Credit Facility was 4.46% and 3.86%, respectively. Average borrowings for the three and six months ended September 30, 2023 were $185.1 million and $106.1 million, respectively. For the three and six months ended September 30, 2022, average borrowings were $214.6 million and $198.8 million, respectively. As of September 30, 2023 and 2022, CSWC was in compliance with all financial covenants under the Credit Agreement. 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 Existing January 2026 Notes were issued at par. In February 2021, the Company issued an additional $65.0 million in aggregate principal amount of the January 2026 Notes (the "Additional January 2026 Notes" together with the Existing January 2026 Notes, the "January 2026 Notes"). The Additional January 2026 Notes were issued at a price of 102.11% of the aggregate principal amount of the Additional January 2026 Notes, resulting in a yield-to-maturity of approximately 4.0% at issuance. The Additional January 2026 Notes are treated as a single series with the Existing January 2026 Notes under the indenture and have the same terms as the Existing January 2026 Notes. The January 2026 Notes mature on January 31, 2026 and may be redeemed in whole or in part at any time prior to October 31, 2025, at par plus a "make-whole" premium, and thereafter at par. The January 2026 Notes bear interest at a rate of 4.50% per year, payable semi-annually on January 31 and July 31 of each year. The January 2026 Notes 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 Facility and the SBA Debentures. As of September 30, 2023, the carrying amount, which includes unamortized debt issuance costs, of the January 2026 Notes was $139.2 million on an aggregate principal amount of $140.0 million at a weighted average effective yield of 4.46%. As of September 30, 2023, the fair value of the January 2026 Notes was $117.3 million. This is a Level 3 fair value measurement under ASC 820 based on a valuation model using a discounted cash flow analysis. The Company recognized interest expense related to the January 2026 Notes, including amortization of deferred issuance costs, of $1.7 million and $3.3 million, respectively, for each of the three and six months ended September 30, 2023 and 2022. For each of the three and six months ended September 30, 2023 and 2022, average borrowings were $140.0 million. The indenture governing the January 2026 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 January 2026 Notes and the trustee under the indenture if the Company is no longer subject to the reporting requirements under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). These covenants are subject to important limitations and exceptions that are described in the indenture and the third supplemental indenture relating to the January 2026 Notes. In addition, holders of the January 2026 Notes can require the Company to repurchase some or all of the January 2026 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 third supplemental indenture relating to the January 2026 Notes. October 2026 Notes In August 2021, the Company issued $100.0 million in aggregate principal amount of 3.375% Notes due 2026 (the "Existing October 2026 Notes"). The Existing October 2026 Notes were issued at a price of 99.418% of the aggregate principal amount of the Existing October 2026 Notes, resulting in a yield-to-maturity of 3.5%. In November 2021, the Company issued an additional $50.0 million in aggregate principal amount of the October 2026 Notes (the "Additional October 2026 Notes" together with the Existing October 2026 Notes, the "October 2026 Notes"). The Additional October 2026 Notes were issued at a price of 99.993% of the aggregate principal amount, resulting in a yield-to-maturity of approximately 3.375% at issuance. The Additional October 2026 Notes are treated as a single series with the Existing October 2026 Notes under the indenture and have the same terms as the Existing October 2026 Notes. The October 2026 Notes mature on October 1, 2026 and may be redeemed in whole or in part at any time prior to July 1, 2026, at par plus a "make-whole" premium, and thereafter at par. The October 2026 Notes bear interest at a rate of 3.375% per year, payable semi-annually in arrears on April 1 and October 1 of each year. The October 2026 Notes 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 Facility and the SBA Debentures. As of September 30, 2023, the carrying amount, which includes unamortized debt issuance costs, of the October 2026 Notes was $147.6 million on an aggregate principal amount of $150.0 million at a weighted average effective yield of 3.5%. As of September 30, 2023, the fair value of the October 2026 Notes was $126.1 million. This is a Level 3 fair value measurement under ASC 820 based on a valuation model using a discounted cash flow analysis. The Company recognized interest expense related to the October 2026 Notes, including amortization of deferred issuance costs, of $1.5 million and $2.9 million for the three and six months ended September 30, 2023, respectively. For the three and six months ended September 30, 2022, the Company recognized interest expense of $1.4 million and $2.9 million, respectively. For each of the three and six months ended September 30, 2023 and 2022, average borrowings were $150.0 million. The indenture governing the October 2026 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 October 2026 Notes and the trustee under the indenture if the Company is no longer subject to the reporting requirements under the Exchange Act.

August 2028 Notes In June 2023, the Company issued approximately $71.9 million in aggregate principal amount, including the underwriters' full exercise of their option to purchase an additional $9.4 million in aggregate principal amount to cover over-allotments, of 7.75% notes due 2028 (the "August 2028 Notes"). The August 2028 Notes mature on August 1, 2028 and may be redeemed in whole or in part at any time, or from time to time, at the Company’s option on or after August 1, 2025. The August 2028 Notes bear interest at a rate of 7.75% per year, payable quarterly on February 1, May 1, August 1 and November 1 of each year, beginning on August 1, 2023. The August 2028 Notes 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 Facility and the SBA Debentures. The August 2028 Notes are listed on the Nasdaq Global Select Market under the trading symbol "CSWCZ." As of September 30, 2023, the carrying amount, which includes unamortized debt issuance costs, of the August 2028 Notes was $69.4 million on an aggregate principal amount of $71.9 million at a weighted average effective yield of 7.75%.

The fair value 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 Company recognized interest expense related to the August 2028 Notes, including amortization of deferred issuance costs, of $1.5 million and $1.8 million for the three and six months ended September 30, 2023, respectively. Since the issuance of the August 2028 Notes on June 14, 2023 through September 30, 2023, average borrowings were $71.9 million. 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. These covenants are subject to important limitations and exceptions that are described in the indenture and the fifth supplemental indenture relating to the August 2028 Notes. SBA Debentures On April 20, 2021, SBIC I 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 license allows SBIC I 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 which 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 to borrow up to $175 million in SBA Debentures with at least $87.5 million in regulatory capital (as defined in the SBA regulations). On May 25, 2021, SBIC I received a leverage commitment from the SBA in the amount of $40.0 million to be issued on or prior to September 30, 2025. On January 28, 2022, SBIC I received an additional leverage commitment in the amount of $40.0 million to be issued on or prior to September 30, 2026. On November 22, 2022, SBIC I received an additional leverage commitment in the amount of $50.0 million to be issued on or prior to September 30, 2027. The SBA may limit the amount that may be drawn each year under these commitments, and each issuance of leverage is conditioned on the Company’s full compliance, as determined by the SBA, with the terms and conditions set forth in the SBA regulations. As of September 30, 2023, SBIC I had regulatory capital of $87.5 million and leverageable capital of $79.0 million. As of September 30, 2023, all approved SBA Debenture commitments have been utilized. As of September 30, 2023, the carrying amount of SBA Debentures was $126.4 million on an aggregate principal amount of $130.0 million. As of September 30, 2023, the fair value of the SBA Debentures was $116.2 million. The fair value of the SBA Debentures is estimated by discounting the remaining payments using current market rates for similar instruments and considering such factors as the legal maturity date and the ability of market participants to prepay the SBA Debentures, which are Level 3 inputs under ASC 820. The Company recognized interest expense and fees related to SBA Debentures of $1.5 million and $2.9 million for the three and six months ended September 30, 2023, respectively. For the three and six months ended September 30, 2022, the Company recognized interest expense of $0.6 million and $1.0 million, respectively. The weighted average interest rate on the SBA Debentures was 4.23% and 4.09% for the three and six months ended September 30, 2023, respectively. For the three and six months ended September 30, 2022, the weighted average interest rate on the SBA Debentures was 2.58% and 2.55%, respectively. For the three and six months ended September 30, 2023, average borrowings were $128.2 million and $126.0 million, respectively. For the three and six months ended September 30, 2022, average borrowings were $80.0 million and $65.9 million, respectively. As of September 30, 2023, the Company's issued and outstanding SBA Debentures mature as follows (amounts in thousands): Pooling Date (1) Maturity Date Fixed Interest Rate September 30, 2023 9/22/2021 9/1/2031 1.575% $ 15,000 3/23/2022 3/1/2032 3.209% 25,000 9/21/2022 9/1/2032 4.435% 40,000 3/22/2023 3/1/2033 5.215% 40,000 9/20/2023 9/1/2033 5.735% 10,000 $ 130,000 (1) The SBA has two scheduled pooling dates for SBA Debentures (in March and in September). Certain SBA Debentures funded during the reporting periods may not be pooled until the subsequent pooling date.

INCOME TAXES

INCOME TAXES	Sep. 30, 2023
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES We have elected, and intend to qualify annually, to be treated for U.S. federal income tax purposes as a RIC under Subchapter M of the Code and have a tax year end of December 31. In order to qualify as a RIC, we must annually distribute at least 90% of our investment company taxable income, as defined by the Code, to our shareholders in a timely manner. Investment company income generally includes net short-term capital gains but excludes net long-term capital gains. A RIC is not subject to federal income tax on the portion of its ordinary income and capital gains that is distributed to its shareholders, including “deemed distributions” as discussed below. As part of maintaining RIC tax treatment, undistributed taxable income and capital gain, which is subject to a 4% non-deductible U.S. federal excise tax, pertaining to a given fiscal year may be distributed up to 12 months subsequent to the end of that fiscal year, provided such dividends are declared on or prior to the later of (1) the extended due date of the U.S. federal income tax return for the applicable fiscal year and (2) the fifteenth day of the ninth month following the close of the year in which such taxable income was generated. As of September 30, 2023, CSWC qualified for RIC tax treatment. We intend to meet the applicable qualifications to be taxed as a RIC in future periods. However, the Company’s ability to meet certain portfolio diversification requirements of RICs in future years may not be controllable by the Company. The determination of the tax attributes for CSWC’s distributions is made annually, based upon its taxable income for the full year and distributions paid for the full year. Therefore, any determination made on an interim basis is forward-looking based on currently available facts, rules and assumptions and may not be representative of the actual tax attributes of distributions for a full year. During the quarter ended September 30, 2023, CSWC declared and paid a quarterly dividend in the amount of $24.8 million, or $0.62 per share ($0.56 per share in regular dividends and $0.06 per share in supplemental dividends). During the quarter ended June 30, 2023, CSWC declared and paid a quarterly dividend in the amount of $22.9 million, or $0.59 per share ($0.54 per share in regular dividends and $0.05 per share in supplemental dividends). During the quarter ended March 31, 2023, CSWC declared and paid a quarterly dividend in the amount of $20.9 million, or $0.58 per share ($0.53 per share in regular dividends and $0.05 per share in supplemental dividends). Ordinary dividend distributions from a RIC do not qualify for the 20% maximum tax rate on dividend income from domestic corporations and qualified foreign corporations, except to the extent that the RIC received the income in the form of qualifying dividends from domestic corporations and qualified foreign corporations. The tax attributes for distributions will generally include both ordinary income and capital gains, but may also include qualified dividends or return of capital. The following reconciles net increase in net assets resulting from operations to estimated RIC taxable income for the six months ended September 30, 2023 and 2022: Six Months Ended September 30, Reconciliation of RIC Distributable Income 1 2023 2022 Net increase in net assets from operations $ 46,436 $ 11,968 Net unrealized (appreciation) depreciation on investments (7,439) 8,599 (Expense/loss) income/gain recognized for tax on pass-through entities (4,184) 35 (Gain) loss recognized on dispositions (1,641) (159) Capital loss carryover 2 16,733 6,622 Net operating income - wholly-owned subsidiary (2,990) (1,568) Dividend income from wholly-owned subsidiary — 745 Non-deductible tax expense 252 251 Loss on extinguishment of debt (1,363) (1,363) Non-deductible compensation 1,785 1,644 Compensation related book/tax differences (3,851) (3,583) Interest on non-accrual loans 2,999 1,992 Other book/tax differences 2,525 805 Estimated distributable income before deductions for distributions $ 49,262 $ 25,988 1 The calculation of taxable income for each period is an estimate and will not be finally determined until the Company files its tax return each year. Final taxable income may be different than this estimate. 2 At September 30, 2023, the Company had long-term capital loss carryforwards of $46.9 million to offset future capital gains. These capital loss carryforwards are not subject to expiration. A RIC may elect to retain all or a portion of its net capital gains by designating them as a “deemed distribution” to its shareholders and paying a federal tax on the net capital gains for the benefit of its shareholders. Shareholders then report their share of the retained capital gains on their income tax returns as if it had been received and report a tax credit for tax paid on their behalf by the RIC. Shareholders then add the amount of the “deemed distribution” net of such tax to the basis of their shares. In addition, the Taxable Subsidiary holds a portion of one or more of our portfolio investments that are listed on the Consolidated Schedule of Investments. The Taxable Subsidiary is consolidated for financial reporting purposes in accordance with U.S. GAAP, so that our consolidated financial statements reflect our investments in the portfolio companies owned by the Taxable Subsidiary. The purpose of the Taxable Subsidiary is to permit us to hold certain interests in portfolio companies that are organized as limited liability companies, or LLCs (or other forms of pass-through entities) and still satisfy the RIC tax requirement that at least 90% of our gross income for U.S. federal income tax purposes must consist of qualifying investment income. Absent the Taxable Subsidiary, a proportionate amount of any gross income of a partnership or LLC (or other pass-through entity) portfolio investment would flow through directly to us. To the extent that our income did not consist of investment income, it could jeopardize our ability to qualify as a RIC and therefore cause us to incur significant amounts of U.S. federal income taxes at corporate rates. Where interests in LLCs (or other pass-through entities) are owned by the Taxable Subsidiary, however, the income from those interests is taxed to the Taxable Subsidiary and does not flow through to us, thereby helping us preserve our RIC tax treatment and resultant tax advantages. The Taxable Subsidiary is not consolidated for U.S. federal income tax purposes and may generate an income tax provision as a result of their ownership of the portfolio companies. The income tax provision, or benefit, and the related tax assets and liabilities, if any, are reflected in our Consolidated Statement of Operations. As of September 30, 2023, the cost of investments held at the RIC for U.S. federal income tax purposes was $1,304.5 million, with such investments having gross unrealized appreciation of $17.3 million and gross unrealized depreciation of $71.0 million, resulting in net unrealized depreciation of $53.7 million. As of September 30, 2023, the cost of investments held at the Taxable Subsidiary for U.S. federal income tax purposes was $45.1 million, with such investments having gross unrealized appreciation of $62.0 million and gross unrealized depreciation of $4.3 million, resulting in net unrealized appreciation of $57.7 million. On a consolidated basis, the total investment portfolio has net unrealized appreciation of $4.0 million for U.S. federal income tax purposes. The taxable income, or loss, of the Taxable Subsidiary may differ from book income, or loss, due to temporary book and tax timing differences and permanent differences. This income tax provision, or benefit, if any, and the related tax assets and liabilities, are reflected in our consolidated financial statements. The Taxable Subsidiary records valuation adjustments related to its investments on a quarterly basis. Deferred taxes related to the unrealized gain/loss on investments are also recorded on a quarterly basis. A valuation allowance is provided against deferred tax assets when it is more likely than not that some portion or all of the deferred tax asset will not be realized. Establishing a valuation allowance of a deferred tax asset requires management to make estimates related to expectations of future taxable income. As of September 30, 2023 and March 31, 2023, the Taxable Subsidiary had a deferred tax liability of $10.4 million and $12.1 million, respectively. Based on our assessment of our unrecognized tax benefits, management believes that all benefits will be realized and they do not contain any uncertain tax positions. The following table sets forth the significant components of the deferred tax assets and liabilities as of September 30, 2023 and March 31, 2023 (amounts in thousands): September 30, 2023 March 31, 2023 Deferred tax asset: Net operating loss carryforwards $ 159 $ — Interest 966 219 Total deferred tax asset 1,125 219 Deferred tax liabilities: Net unrealized appreciation on investments (10,350) (11,413) Net basis differences in portfolio investments (1,133) (923) Total deferred tax liabilities (11,483) (12,336) Total net deferred tax (liabilities) assets $ (10,358) $ (12,117) The income tax provision, or benefit, and the related tax assets and liabilities, generated by CSWC and the Taxable Subsidiary, if any, are reflected in CSWC’s consolidated financial statements. For the three months ended September 30, 2023, we recognized a net income tax benefit of $0.8 million, principally consisting of a $0.1 million accrual for U.S. federal excise tax and a $0.9 million tax benefit relating to the Taxable Subsidiary. For the six months ended September 30, 2023, we recognized a net income tax benefit of $0.3 million, principally consisting of a $0.3 million accrual for U.S. federal excise tax and a $0.6 million tax benefit relating to the Taxable Subsidiary. For the three months ended September 30, 2022, we recognized a net income tax provision of $0.5 million, principally consisting of a $0.2 million accrual for U.S. federal excise tax and $0.3 million of tax provision relating to the Taxable Subsidiary. For the six months ended September 30, 2022, we recognized a net income tax provision of $0.7 million, principally consisting of a $0.3 million accrual for U.S. federal excise tax and a $0.4 million tax provision relating to the Taxable Subsidiary. Although we believe our tax returns are correct, the final determination of tax examinations could be different from what was reported on the returns. In our opinion, we have made adequate tax provisions for years subject to examination. Generally, we are currently open to audit under the statute of limitations by the Internal Revenue Service as well as state taxing authorities for the years ended December 31, 2020 through December 31, 2022.

STOCK BASED COMPENSATION PLANS	Sep. 30, 2023
Share-Based Payment Arrangement [Abstract]
STOCK BASED COMPENSATION PLANS	STOCK BASED COMPENSATION PLANS Under the 2010 Plan and the 2021 Employee Plan, a restricted stock award is an award of shares of our common stock, which have full voting and dividend rights but are restricted with regard to sale or transfer. Restricted stock awards are independent of stock grants and are generally subject to forfeiture if employment terminates prior to these restrictions lapsing. Unless otherwise specified in the award agreement, these shares vest in equal annual installments over a four-year period from the grant date and are expensed over the vesting period starting on the grant date. The right to grant restricted stock awards under the 2010 Plan terminated on July 18, 2021, ten years after the date that the 2010 Plan was approved by the Company’s shareholders pursuant to its terms. In connection with the termination of the 2010 Plan, the Board of Directors and shareholders approved the 2021 Employee Plan as part of the compensation packages for its employees, the terms of which are, in all material respects, identical to the 2010 Plan. The 2021 Employee Plan makes available for issuance 1,200,000 shares of common stock. As of September 30, 2023, there are 722,267 shares of common stock available for issuance under the 2021 Employee Plan. In addition, the Board of Directors and shareholders approved the Non-Employee Director Plan as part of the compensation package for non-employee directors of the Board of Directors. Under the Non-Employee Director Plan, at the beginning of each one-year term of service on our Board, each non-employee director will receive a number of shares equivalent to $50,000 based on the market value at the close of the Nasdaq Global Select Market on the date of grant. These shares will vest one year from the date of the grant and are expensed over the one-year term of non-employee directors. The Non-Employee Director Plan makes available for issuance 120,000 shares of common stock. As of September 30, 2023, there were 96,695 shares of common stock available for issuance under the Non-Employee Director Plan. We expense the cost of the restricted stock awards, which is determined to equal the fair value of the restricted stock award at the date of grant on a straight-line basis over the requisite service period. For these purposes, the fair value of the restricted stock award is determined based upon the closing price of our common stock on the date of the grant. During the three months ended September 30, 2023 and 2022, we recognized total share based compensation expense of $1.2 million (of which $0.1 million was related to restricted stock issued to non-employee directors) and $1.1 million (of which $35.5 thousand was related to restricted stock issued to non-employee directors), respectively, related to the restricted stock issued. During the six months ended September 30, 2023 and 2022, we recognized total share based compensation expense of $2.2 million (of which $0.1 million was related to restricted stock issued to non-employee directors) and $1.9 million (of which $35.5 thousand was related to restricted stock issued to non-employee directors), respectively, related to the restricted stock issued. As of September 30, 2023, the total remaining unrecognized compensation expense related to non-vested restricted stock awards was $10.6 million, which will be amortized over the weighted-average vesting period of approximately 2.8 years. The following table summarizes the restricted stock outstanding under the 2010 Plan and the 2021 Employee Plan as of September 30, 2023: Weighted Average Weighted Average Fair Value Per Remaining Vesting Restricted Stock Awards Number of Shares Share at grant date Term (in Years) Unvested at March 31, 2023 432,711 $ 21.61 2.4 Granted 284,407 19.86 — Vested (139,386) 20.91 — Forfeited (1,791) 23.91 — Unvested at September 30, 2023 575,941 $ 20.91 2.8 The following table summarizes the restricted stock outstanding under the Non-Employee Director Plan as of September 30, 2023: Weighted Average Weighted Average Fair Value Per Remaining Vesting Restricted Stock Awards Number of Shares Share at grant date Term (in Years) Unvested at March 31, 2023 12,105 $ 20.66 0.4 Granted 11,200 — — Vested (12,105) — — Forfeited — — — Unvested at September 30, 2023 11,200 $ 22.33 0.9

The 401K Plan permits employees to defer a portion of their total annual compensation up to the Internal Revenue Service annual maximum based on age and eligibility. We made contributions to the 401K Plan of up to 4.5% of the Internal Revenue Service’s annual maximum eligible compensation, all of which is fully vested immediately. During the three months ended September 30, 2023 and 2022, we made matching contributions of approximately $34.5 thousand and $31.4 thousand, respectively. During each of the six months ended September 30, 2023 and 2022, we made matching contributions of approximately $0.1 million.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Commitments In the normal course of business, the Company is a party to financial instruments with off-balance sheet risk, consisting primarily of unused commitments to extend financing to the Company’s portfolio companies. Because commitments may expire without being drawn upon, the total commitment amount does not necessarily represent future cash requirements. Additionally, our commitment to fund delayed draw term loans generally is triggered upon the satisfaction of certain pre-negotiated terms and conditions, such as meeting certain financial performance hurdles or financial covenants, which may limit a borrower's ability to draw on such delayed draw term loans.

General Description of Registrant [Abstract]
Investment Objectives and Practices [Text Block]	We are an internally managed closed-end, non-diversified management investment company that has elected to be regulated as a BDC under the 1940 Act. We specialize in providing customized debt and equity financing to LMM companies and debt capital to UMM companies in a broad range of investment segments located primarily in the United States. Our investment objective is to produce attractive risk-adjusted returns by generating current income from our debt investments and capital appreciation from our equity and equity related investments. Our investment strategy is to partner with business owners, management teams and financial sponsors to provide flexible financing solutions to fund growth, changes of control, or other corporate events. We invest primarily in senior debt securities, secured by security interests in portfolio company assets. We also invest in equity interests in our portfolio companies alongside our debt securities. We focus on investing in companies with histories of generating revenues and positive cash flow, established market positions and proven management teams with strong operating discipline. We primarily target senior debt and equity investments in LMM companies, and opportunistically target first and second lien loans in UMM companies. Our target LMM companies typically have annual EBITDA between $3.0 million and $20.0 million, and our LMM investments generally range in size from $5.0 million to $35.0 million. Our UMM investments generally include first and second lien loans in companies with EBITDA generally greater than $20.0 million, and our UMM investments typically range in size from $5.0 million to $20.0 million. We seek to fill the financing gap for LMM companies, which, historically, have had more limited access to financing from commercial banks and other traditional sources. The underserved nature of the LMM creates the opportunity for us to meet the financing needs of LMM companies while also negotiating favorable transaction terms and equity participations. Our ability to invest across a LMM company’s capital structure, from secured loans to equity securities, allows us to offer portfolio companies a comprehensive suite of financing options. Providing customized financing solutions is important to LMM companies. We generally seek to partner directly with financial sponsors, entrepreneurs, management teams and business owners in making our investments. Our LMM debt investments typically include senior loans with a first lien on the assets of the portfolio company. Our LMM debt investments typically have a term of between five and seven years from the original investment date. We also often seek to invest in the equity securities of our LMM portfolio companies. Our investments in UMM companies primarily consist of direct investments in or secondary purchases of interest bearing debt securities in privately held companies that are generally larger in size than the LMM companies included in our portfolio. Our UMM debt investments are generally secured by either a first or second priority lien on the assets of the portfolio company and typically have an expected duration of between three and seven years from the original investment date. Because we are internally managed, we do not pay any external investment advisory fees, but instead directly incur the operating costs associated with employing investment and portfolio management professionals. We believe that our internally managed structure provides us with a beneficial operating expense structure when compared to other publicly traded and privately held investment firms that are externally managed, and our internally managed structure allows us the opportunity to leverage our non-interest operating expenses as we grow our investment portfolio. For the six months ended September 30, 2023 and 2022, the ratio of our last twelve months ("LTM") operating expenses, excluding interest expense, as a percentage of our LTM average total assets was 1.84% and 1.99%, respectively.
Risk Factors [Table Text Block]	Risk Factors Investing in our common stock involves a number of significant risks. There have been no material changes to the risk factors as previously disclosed in our Annual Report on Form 10-K for the fiscal year ended March 31, 2023 that we filed with the SEC on May 23, 2023, other than the risk factor listed below: The alternative reference rates that have replaced LIBOR in our credit arrangements and other financial instruments may not yield the same or similar economic results as LIBOR over the life of such transactions. The London Interbank Offered Rate (“LIBOR”) is an index rate that historically was widely used in lending transactions and was a common reference rate for setting the floating interest rate on private loans. LIBOR was typically the reference rate used in floating-rate loans extended to our portfolio companies. The ICE Benchmark Administration (“IBA”) (the entity that is responsible for calculating LIBOR) ceased providing overnight, one, three, six and twelve months USD LIBOR tenors on June 30, 2023. In addition, the United Kingdom’s Financial Conduct Authority (“FCA”), which oversees the IBA, now prohibits entities supervised by the FCA from using LIBORs, including USD LIBOR, except in very limited circumstances. In the United States, the Secured Overnight Financing Rate (“SOFR”) is the preferred alternative rate for LIBOR. SOFR is a measure of the cost of borrowing cash overnight, collateralized by U.S. Treasury securities, and is based on directly observable U.S. Treasury-backed repurchase transactions. SOFR is published by the Federal Reserve Bank of New York each U.S. Government Securities Business Day, for transactions made on the immediately preceding U.S. Government Securities Business Day. Alternative reference rates that may replace LIBOR, including SOFR for USD transactions, may not yield the same or similar economic results as LIBOR over the lives of such transactions. Substantially all of our loans that referenced LIBOR have been amended to reference the forward-looking term rate published by CME Group Benchmark Administration Limited based on the secured overnight financing rate (“CME Term SOFR”). CME Term SOFR rates are forward-looking rates that are derived by compounding projected overnight SOFR rates over one, three, and six months taking into account the values of multiple consecutive, executed, one-month and three-month CME Group traded SOFR futures contracts and, in some cases, over-the-counter SOFR Overnight Indexed Swaps as an indicator of CME Term SOFR reference rate values. CME Term SOFR and the inputs on which it is based are derived from SOFR. Since CME Term SOFR is a relatively new market rate, there will likely be no established trading market for credit agreements or other financial instruments when they are issued, and an established market may never develop or may not be liquid. Market terms for instruments referencing CME Term SOFR rates may be lower than those of later-issued CME Term SOFR indexed instruments. Similarly, if CME Term SOFR does not prove to be widely used, the trading price of instruments referencing CME Term SOFR may be lower than those of instruments indexed to indices that are more widely used.

Capital Stock, Long-Term Debt, and Other Securities [Abstract]
Long Term Debt [Table Text Block]	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 SBIC I or any future SBIC subsidiary of the Company from the definition of senior securities in the asset coverage requirement applicable to the Company under the 1940 Act. As of September 30, 2023, the Company’s asset coverage was 229%. Credit Facility In August 2016, CSWC entered into a senior secured revolving credit facility (the “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, the "Credit Agreement"). Borrowings under the 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 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 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. CSWC pays unused commitment fees of 0.50% to 1.00% per annum, based on utilization, on the unused lender commitments under the Credit Facility. The 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 Credit Facility is secured by (1) substantially all of the present and future property and assets of the Company and the guarantors and (2) 100% of the equity interests in the Company’s wholly-owned subsidiary. As of September 30, 2023, substantially all of the Company’s assets were pledged as collateral for the Credit Facility, except for assets held by SBIC I. At September 30, 2023, CSWC had $250.0 million in borrowings outstanding under the Credit Facility. CSWC recognized interest expense related to the Credit Facility, including unused commitment fees and amortization of deferred loan costs, of $4.3 million and $9.3 million for the three and six months ended September 30, 2023, respectively. For the three and six months ended September 30, 2022, CSWC recognized interest expense of $2.9 million and $4.8 million, respectively. The weighted average interest rate on the Credit Facility was 7.70% and 7.52% and for the three and six months ended September 30, 2023, respectively. For the three and six months ended September 30, 2022, the weighted average interest rate on the Credit Facility was 4.46% and 3.86%, respectively. Average borrowings for the three and six months ended September 30, 2023 were $185.1 million and $106.1 million, respectively. For the three and six months ended September 30, 2022, average borrowings were $214.6 million and $198.8 million, respectively. As of September 30, 2023 and 2022, CSWC was in compliance with all financial covenants under the Credit Agreement. 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 Existing January 2026 Notes were issued at par. In February 2021, the Company issued an additional $65.0 million in aggregate principal amount of the January 2026 Notes (the "Additional January 2026 Notes" together with the Existing January 2026 Notes, the "January 2026 Notes"). The Additional January 2026 Notes were issued at a price of 102.11% of the aggregate principal amount of the Additional January 2026 Notes, resulting in a yield-to-maturity of approximately 4.0% at issuance. The Additional January 2026 Notes are treated as a single series with the Existing January 2026 Notes under the indenture and have the same terms as the Existing January 2026 Notes. The January 2026 Notes mature on January 31, 2026 and may be redeemed in whole or in part at any time prior to October 31, 2025, at par plus a "make-whole" premium, and thereafter at par. The January 2026 Notes bear interest at a rate of 4.50% per year, payable semi-annually on January 31 and July 31 of each year. The January 2026 Notes 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 Facility and the SBA Debentures. As of September 30, 2023, the carrying amount of the January 2026 Notes was $139.2 million on an aggregate principal amount of $140.0 million at a weighted average effective yield of 4.46%. As of September 30, 2023, the fair value of the January 2026 Notes was $117.3 million. This is a Level 3 fair value measurement under ASC 820 based on a valuation model using a discounted cash flow analysis. The Company recognized interest expense related to the January 2026 Notes, including amortization of deferred issuance costs, of $1.7 million and $3.3 million, respectively, for each of the three and six months ended September 30, 2023 and 2022. For each of the three and six months ended September 30, 2023 and 2022, average borrowings were $140.0 million. The indenture governing the January 2026 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 January 2026 Notes and the trustee under the indenture if the Company is no longer subject to the reporting requirements under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). These covenants are subject to important limitations and exceptions that are described in the indenture and the third supplemental indenture relating to the January 2026 Notes. In addition, holders of the January 2026 Notes can require the Company to repurchase some or all of the January 2026 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 third supplemental indenture relating to the January 2026 Notes. October 2026 Notes In August 2021, the Company issued $100.0 million in aggregate principal amount of 3.375% Notes due 2026 (the "Existing October 2026 Notes"). The Existing October 2026 Notes were issued at a price of 99.418% of the aggregate principal amount of the Existing October 2026 Notes, resulting in a yield-to-maturity of 3.5%. In November 2021, the Company issued an additional $50.0 million in aggregate principal amount of the October 2026 Notes (the "Additional October 2026 Notes" together with the Existing October 2026 Notes, the "October 2026 Notes"). The Additional October 2026 Notes were issued at a price of 99.993% of the aggregate principal amount, resulting in a yield-to-maturity of approximately 3.375% at issuance. The Additional October 2026 Notes are treated as a single series with the Existing October 2026 Notes under the indenture and have the same terms as the Existing October 2026 Notes.

The October 2026 Notes bear interest at a rate of 3.375% per year, payable semi-annually in arrears on April 1 and October 1 of each year. The October 2026 Notes 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 Facility and the SBA Debentures. As of September 30, 2023, the carrying amount of the October 2026 Notes was $147.6 million on an aggregate principal amount of $150.0 million at a weighted average effective yield of 3.5%.

The August 2028 Notes are listed on the Nasdaq Global Select Market under the trading symbol "CSWCZ." As of September 30, 2023, the carrying amount of the August 2028 Notes was $69.4 million on an aggregate principal amount of $71.9 million at a weighted average effective yield of 7.75%. As of September 30, 2023, the fair value of the August 2028 Notes was $73.6 million. The fair value 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 Company recognized interest expense related to the August 2028 Notes, including amortization of deferred issuance costs, of $1.5 million and $1.8 million for the three and six months ended September 30, 2023, respectively. Since the issuance of the August 2028 Notes on June 14, 2023 through September 30, 2023, average borrowings were $71.9 million. 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. These covenants are subject to important limitations and exceptions that are described in the indenture and the fifth supplemental indenture relating to the August 2028 Notes. SBA Debentures On April 20, 2021, SBIC I 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 license allows SBIC I 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 which 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 to borrow up to $175 million in SBA Debentures with at least $87.5 million in regulatory capital (as defined in the SBA regulations). On May 25, 2021, SBIC I received a leverage commitment from the SBA in the amount of $40.0 million to be issued on or prior to September 30, 2025. On January 28, 2022, SBIC I received an additional leverage commitment in the amount of $40.0 million to be issued on or prior to September 30, 2026. On November 22, 2022, SBIC I received an additional leverage commitment in the amount of $50.0 million to be issued on or prior to September 30, 2027. The SBA may limit the amount that may be drawn each year under these commitments, and each issuance of leverage is conditioned on the Company’s full compliance, as determined by the SBA, with the terms and conditions set forth in the SBA regulations. As of September 30, 2023, SBIC I had regulatory capital of $87.5 million and leverageable capital of $79.0 million. As of September 30, 2023, all approved SBA Debenture commitments have been utilized. As of September 30, 2023, the carrying amount of SBA Debentures was $126.4 million on an aggregate principal amount of $130.0 million. As of September 30, 2023, the fair value of the SBA Debentures was $116.2 million. The fair value of the SBA Debentures is estimated by discounting the remaining payments using current market rates for similar instruments and considering such factors as the legal maturity date and the ability of market participants to prepay the SBA Debentures, which are Level 3 inputs under ASC 820. The Company recognized interest expense and fees related to SBA Debentures of $1.5 million and $2.9 million for the three and six months ended September 30, 2023, respectively. For the three and six months ended September 30, 2022, the Company recognized interest expense of $0.6 million and $1.0 million, respectively. The weighted average interest rate on the SBA Debentures was 4.23% and 4.09% for the three and six months ended September 30, 2023, respectively. For the three and six months ended September 30, 2022, the weighted average interest rate on the SBA Debentures was 2.58% and 2.55%, respectively. For the three and six months ended September 30, 2023, average borrowings were $128.2 million and $126.0 million, respectively. For the three and six months ended September 30, 2022, average borrowings were $80.0 million and $65.9 million, respectively. As of September 30, 2023, the Company's issued and outstanding SBA Debentures mature as follows (amounts in thousands): Pooling Date (1) Maturity Date Fixed Interest Rate September 30, 2023 9/22/2021 9/1/2031 1.575% $ 15,000 3/23/2022 3/1/2032 3.209% 25,000 9/21/2022 9/1/2032 4.435% 40,000 3/22/2023 3/1/2033 5.215% 40,000 9/20/2023 9/1/2033 5.735% 10,000 $ 130,000
Alternative Reference Rates Economic Results Risk [Member]
General Description of Registrant [Abstract]
Risk [Text Block]	The alternative reference rates that have replaced LIBOR in our credit arrangements and other financial instruments may not yield the same or similar economic results as LIBOR over the life of such transactions. The London Interbank Offered Rate (“LIBOR”) is an index rate that historically was widely used in lending transactions and was a common reference rate for setting the floating interest rate on private loans. LIBOR was typically the reference rate used in floating-rate loans extended to our portfolio companies. The ICE Benchmark Administration (“IBA”) (the entity that is responsible for calculating LIBOR) ceased providing overnight, one, three, six and twelve months USD LIBOR tenors on June 30, 2023. In addition, the United Kingdom’s Financial Conduct Authority (“FCA”), which oversees the IBA, now prohibits entities supervised by the FCA from using LIBORs, including USD LIBOR, except in very limited circumstances. In the United States, the Secured Overnight Financing Rate (“SOFR”) is the preferred alternative rate for LIBOR. SOFR is a measure of the cost of borrowing cash overnight, collateralized by U.S. Treasury securities, and is based on directly observable U.S. Treasury-backed repurchase transactions. SOFR is published by the Federal Reserve Bank of New York each U.S. Government Securities Business Day, for transactions made on the immediately preceding U.S. Government Securities Business Day. Alternative reference rates that may replace LIBOR, including SOFR for USD transactions, may not yield the same or similar economic results as LIBOR over the lives of such transactions. Substantially all of our loans that referenced LIBOR have been amended to reference the forward-looking term rate published by CME Group Benchmark Administration Limited based on the secured overnight financing rate (“CME Term SOFR”). CME Term SOFR rates are forward-looking rates that are derived by compounding projected overnight SOFR rates over one, three, and six months taking into account the values of multiple consecutive, executed, one-month and three-month CME Group traded SOFR futures contracts and, in some cases, over-the-counter SOFR Overnight Indexed Swaps as an indicator of CME Term SOFR reference rate values. CME Term SOFR and the inputs on which it is based are derived from SOFR. Since CME Term SOFR is a relatively new market rate, there will likely be no established trading market for credit agreements or other financial instruments when they are issued, and an established market may never develop or may not be liquid. Market terms for instruments referencing CME Term SOFR rates may be lower than those of later-issued CME Term SOFR indexed instruments. Similarly, if CME Term SOFR does not prove to be widely used, the trading price of instruments referencing CME Term SOFR may be lower than those of instruments indexed to indices that are more widely used.

Long Term Debt, Title [Text Block]	August 2028 Notes
Long Term Debt, Structuring [Text Block]	In June 2023, the Company issued approximately $71.9 million in aggregate principal amount, including the underwriters' full exercise of their option to purchase an additional $9.4 million in aggregate principal amount to cover over-allotments, of 7.75% notes due 2028 (the "August 2028 Notes"). The August 2028 Notes mature on August 1, 2028 and may be redeemed in whole or in part at any time, or from time to time, at the Company’s option on or after August 1, 2025. The August 2028 Notes bear interest at a rate of 7.75% per year, payable quarterly on February 1, May 1, August 1 and November 1 of each year, beginning on August 1, 2023. The August 2028 Notes 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 Facility and the SBA Debentures. The August 2028 Notes are listed on the Nasdaq Global Select Market under the trading symbol "CSWCZ."

Long Term Debt, Title [Text Block]	Credit Facility
Long Term Debt, Structuring [Text Block]	In August 2016, CSWC entered into a senior secured revolving credit facility (the “Credit Facility”) to provide additional liquidity to support its investment and operational activities. The Credit Facility is secured by (1) substantially all of the present and future property and assets of the Company and the guarantors and (2) 100% of the equity interests in the Company’s wholly-owned subsidiary. As of September 30, 2023, substantially all of the Company’s assets were pledged as collateral for the Credit Facility, except for assets held by SBIC I. At September 30, 2023, CSWC had $250.0 million in borrowings outstanding under the Credit Facility. CSWC recognized interest expense related to the Credit Facility, including unused commitment fees and amortization of deferred loan costs, of $4.3 million and $9.3 million for the three and six months ended September 30, 2023, respectively. For the three and six months ended September 30, 2022, CSWC recognized interest expense of $2.9 million and $4.8 million, respectively. The weighted average interest rate on the Credit Facility was 7.70% and 7.52% and for the three and six months ended September 30, 2023, respectively. For the three and six months ended September 30, 2022, the weighted average interest rate on the Credit Facility was 4.46% and 3.86%, respectively. Average borrowings for the three and six months ended September 30, 2023 were $185.1 million and $106.1 million, respectively. For the three and six months ended September 30, 2022, average borrowings were $214.6 million and $198.8 million, respectively. As of September 30, 2023 and 2022, CSWC was in compliance with all financial covenants under the Credit Agreement.
Long Term Debt, Dividends and Covenants [Text Block]	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.
SBA Debentures [Member]
Capital Stock, Long-Term Debt, and Other Securities [Abstract]
Long Term Debt, Title [Text Block]	SBA Debentures
Long Term Debt, Structuring [Text Block]	On April 20, 2021, SBIC I 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 license allows SBIC I 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 which 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 to borrow up to $175 million in SBA Debentures with at least $87.5 million in regulatory capital (as defined in the SBA regulations). On May 25, 2021, SBIC I received a leverage commitment from the SBA in the amount of $40.0 million to be issued on or prior to September 30, 2025. On January 28, 2022, SBIC I received an additional leverage commitment in the amount of $40.0 million to be issued on or prior to September 30, 2026. On November 22, 2022, SBIC I received an additional leverage commitment in the amount of $50.0 million to be issued on or prior to September 30, 2027. The SBA may limit the amount that may be drawn each year under these commitments, and each issuance of leverage is conditioned on the Company’s full compliance, as determined by the SBA, with the terms and conditions set forth in the SBA regulations. As of September 30, 2023, SBIC I had regulatory capital of $87.5 million and leverageable capital of $79.0 million. As of September 30, 2023, all approved SBA Debenture commitments have been utilized. As of September 30, 2023, the carrying amount of SBA Debentures was $126.4 million on an aggregate principal amount of $130.0 million. As of September 30, 2023, the fair value of the SBA Debentures was $116.2 million. The fair value of the SBA Debentures is estimated by discounting the remaining payments using current market rates for similar instruments and considering such factors as the legal maturity date and the ability of market participants to prepay the SBA Debentures, which are Level 3 inputs under ASC 820. The Company recognized interest expense and fees related to SBA Debentures of $1.5 million and $2.9 million for the three and six months ended September 30, 2023, respectively. For the three and six months ended September 30, 2022, the Company recognized interest expense of $0.6 million and $1.0 million, respectively. The weighted average interest rate on the SBA Debentures was 4.23% and 4.09% for the three and six months ended September 30, 2023, respectively. For the three and six months ended September 30, 2022, the weighted average interest rate on the SBA Debentures was 2.58% and 2.55%, respectively. For the three and six months ended September 30, 2023, average borrowings were $128.2 million and $126.0 million, respectively. For the three and six months ended September 30, 2022, average borrowings were $80.0 million and $65.9 million, respectively. As of September 30, 2023, the Company's issued and outstanding SBA Debentures mature as follows (amounts in thousands): Pooling Date (1) Maturity Date Fixed Interest Rate September 30, 2023 9/22/2021 9/1/2031 1.575% $ 15,000 3/23/2022 3/1/2032 3.209% 25,000 9/21/2022 9/1/2032 4.435% 40,000 3/22/2023 3/1/2033 5.215% 40,000 9/20/2023 9/1/2033 5.735% 10,000 $ 130,000

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Sep. 30, 2023
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements have been prepared in accordance with U.S. GAAP. We meet the definition of an investment company and follow the accounting and reporting guidance in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946, Financial Services – Investment Companies
Fair Value Measurements	Fair Value Measurements We account for substantially all of our financial instruments at fair value in accordance with ASC Topic 820, Fair Value Measurements and Disclosures (“ASC 820”). ASC 820 defines fair value, establishes a framework used to measure fair value and requires disclosures for fair value measurements, including the categorization of financial instruments into a three-level hierarchy based on the transparency of valuation inputs. ASC 820 requires disclosure of the fair value of financial instruments for which it is practical to estimate such value. We believe that the carrying amounts of our financial instruments such as cash, receivables and payables approximate the fair value of these items due to the short maturity of these instruments. This is considered a Level 1 valuation technique. The carrying value of our credit facility approximates fair value (Level 3 input). See Note 4 below for further discussion regarding the fair value measurements and hierarchy.
Investments	Investments Investments are stated at fair value and are determined by the Valuation Committee as the Valuation Designee pursuant to Rule 2a-5 under the 1940 Act, subject to the oversight of our Board of Directors, as described in the Notes to the Consolidated Schedule of Investments and Notes 3 and 4 below. Investments are recorded on a trade date basis. Net Realized Gains or Losses and Net Unrealized Appreciation or Depreciation Realized gains or losses are measured by the difference between the net proceeds from the sale or redemption of an investment or a financial instrument and the cost basis of the investment or financial instrument, without regard to unrealized appreciation or depreciation previously recognized, and includes investments written-off during the period net of recoveries and realized gains or losses from in-kind redemptions. Net unrealized appreciation or depreciation reflects the net change in the fair value of the investment portfolio and financial instruments and the reclassification of any prior period unrealized appreciation or depreciation on exited investments and financial instruments to realized gains or losses. Investment Valuation Process Beginning as of the fiscal quarter ended June 30, 2023, pursuant to Rule 2a-5 under the 1940 Act, the Board of Directors has designated the Valuation Committee comprised of certain officers of the Company as the Valuation Designee to determine the fair value of the Company's investments that do not have readily available market quotations, subject to the oversight of the Board of Directors. The valuation process is led by the valuation team and the Valuation Committee in conjunction with the investment team. The process includes a quarterly review of each investment by our valuation team and the Valuation Committee. Valuations of each portfolio security are prepared quarterly by the valuation team using updated financial and other operational information collected from the investment team. In conjunction with the internal valuation process, the Valuation Committee also has engaged multiple independent consulting firms specializing in financial due diligence, valuation, and business advisory services to provide third-party valuation reviews and an independent range of values for selected investments, which is presented to the Valuation Committee. CSWC also uses a standard internal investment rating system in connection with its investment oversight, portfolio management, and investment valuation procedures for its debt portfolio. This system takes into account both quantitative and qualitative factors of the portfolio company and the investments held therein.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents, which consist of cash and highly liquid investments with an original maturity of three months or less at the date of purchase, are carried at cost, which approximates fair value. Cash may be held in a money market fund from time to time, which is a Level 1 security. At September 30, 2023 and March 31, 2023, cash held in money market funds amounted to $7.1 million and $8.9 million, respectively. Cash and cash equivalents includes deposits at financial institutions. We deposit our cash balances in financial institutions and, at times, such balances may be in excess of the Federal Deposit Insurance Corporation (“FDIC”) insurance limits. At September 30, 2023 and March 31, 2023, cash balances totaling $21.7 million and $20.3 million, respectively, exceeded FDIC insurance limits, subjecting us to risk related to the uninsured balance. All of our cash deposits are held at large established high credit quality financial institutions and management believes that the risk of loss associated with any uninsured balances is remote.
Segment Information	Segment Information We operate and manage our business in a singular segment. As an investment company, we invest in portfolio companies in various industries and geographic areas as discussed in Note 3.
Consolidation	Consolidation As permitted under Regulation S-X and ASC 946, we generally do not consolidate our investment in a portfolio company other than an investment company subsidiary or a controlled operating company whose business consists of providing services to CSWC. Accordingly, we consolidate the results of the Taxable Subsidiary and SBIC I. All intercompany balances have been eliminated upon consolidation.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements and
Interest Income	Interest and Dividend Income Interest and dividend income is recorded on an accrual basis to the extent amounts are expected to be collected. Dividend income is recognized on the date dividends are declared by the portfolio company or at the point an obligation exists for the portfolio company to make a distribution. Discounts/premiums received to par on loans purchased are capitalized and accreted or amortized into income over the life of the loan using the effective interest method. In accordance with our valuation policy, accrued interest and dividend income is evaluated quarterly for collectability. When we do not expect the debtor to be able to service all of its debt or other obligations, we generally will establish a reserve against interest income receivable, thereby placing the loan or debt security on non-accrual status, and cease to recognize interest income on that loan or debt security until the borrower has demonstrated the ability and intent to pay contractual amounts due. If a loan or debt security’s status significantly improves regarding its ability to service debt or other obligations, it will be restored to accrual basis. As of September 30, 2023, investments on non-accrual status represented approximately 2.0% of our total investment portfolio's fair value and approximately 2.9% of its cost. As of March 31, 2023, investments on non-accrual status represented approximately 0.3% of our total investment portfolio's fair value and approximately 1.3% of its cost. To maintain RIC tax treatment, non-cash sources of income, such as accretion of interest income, may need to be paid out to shareholders in the form of distributions, even though CSWC may not have collected the interest income. For the three months ended September 30, 2023 and 2022, approximately 3.4% and 3.6%, respectively, of CSWC's total investment income was attributable to non-cash interest income for the accretion of discounts associated with debt investments, net of any premium reduction. For the six months ended September 30, 2023 and 2022, approximately 3.2% and 3.7%, respectively, of CSWC's total investment income was attributable to non-cash interest income for the accretion of discounts associated with debt investments, net of any premium reduction.
Dividends Income	Interest and Dividend Income Interest and dividend income is recorded on an accrual basis to the extent amounts are expected to be collected. Dividend income is recognized on the date dividends are declared by the portfolio company or at the point an obligation exists for the portfolio company to make a distribution. Discounts/premiums received to par on loans purchased are capitalized and accreted or amortized into income over the life of the loan using the effective interest method. In accordance with our valuation policy, accrued interest and dividend income is evaluated quarterly for collectability. When we do not expect the debtor to be able to service all of its debt or other obligations, we generally will establish a reserve against interest income receivable, thereby placing the loan or debt security on non-accrual status, and cease to recognize interest income on that loan or debt security until the borrower has demonstrated the ability and intent to pay contractual amounts due. If a loan or debt security’s status significantly improves regarding its ability to service debt or other obligations, it will be restored to accrual basis. As of September 30, 2023, investments on non-accrual status represented approximately 2.0% of our total investment portfolio's fair value and approximately 2.9% of its cost. As of March 31, 2023, investments on non-accrual status represented approximately 0.3% of our total investment portfolio's fair value and approximately 1.3% of its cost.
Fee Income	Fee Income Fee income, generally collected in advance, includes fees for administration and valuation services rendered by the Company. These fees are typically charged annually and are amortized into income over the year. The Company recognizes nonrecurring fees, including prepayment penalties, waiver fees and amendment fees, as fee income when earned. In addition, the Company also may be entitled to an exit fee that is amortized into income over the life of the loan. Loan exit fees to be paid at the termination of the loan are accreted into fee income over the contractual life of the loan.
Warrants	Warrants In connection with the Company's debt investments, the Company may receive warrants or other equity-related securities from the borrower. The Company determines the cost basis of warrants based upon their respective fair values on the date of receipt in proportion to the total fair value of the debt and warrants received. Any resulting difference between the face amount of the debt and its recorded fair value resulting from the assignment of value to the warrants is treated as original issue discount (“OID”), and accreted into interest income using the effective interest method over the term of the debt investment.
Debt	Debt Issuance Costs Debt issuance costs include commitment fees and other costs related to CSWC’s senior secured revolving credit facility, its unsecured notes (as discussed further in Note 5) and the debentures guaranteed by the SBA (the "SBA Debentures"). The costs in connection with the credit facility have been capitalized and are amortized into interest expense over the term of the credit facility. The costs in connection with the unsecured notes and the SBA Debentures are a direct deduction from the related debt liability and amortized into interest expense over the term of the January 2026 Notes (as defined below), the October 2026 Notes (as defined below), the August 2028 Notes (as defined below) and the SBA Debentures. Deferred Offering Costs Deferred offering costs include registration expenses related to our shelf registration statement and expenses related to the launch of the "at-the-market" program through which we can sell, from time to time, shares of our common stock (the "Equity ATM Program"). These expenses consist primarily of SEC registration fees, legal fees and accounting fees incurred related thereto. These expenses are included in other assets on the Consolidated Statements of Assets and Liabilities. Upon the completion of an equity offering or a debt offering, the deferred expenses are charged to additional paid-in capital or debt issuance costs, respectively. If there are any deferred offering costs remaining at the expiration of the shelf registration statement, these deferred costs are charged to expense.
Leases	Leases The Company is obligated under an operating lease pursuant to which it is leasing an office facility from a third party with a remaining term of approximately 9 years. The operating lease is included as an operating lease right-of-use ("ROU") asset and operating lease liability in the accompanying Consolidated Statements of Assets and Liabilities. The Company does not have any financing leases.
Federal Income Taxes	Federal Income Taxes CSWC has elected, and intends to qualify annually, to be treated for U.S. federal income tax purposes as a RIC under Subsection M of the Code. By meeting these requirements, we will not be subject to U.S. federal income taxes at corporate rates on ordinary income or capital gains timely distributed to shareholders. In order to qualify as a RIC, the Company is required to timely distribute to its shareholders at least 90% of investment company taxable income, as defined by the Code, each year. Investment company taxable income generally differs from net income for financial reporting purposes due to temporary and permanent differences in the recognition of income and expenses. Investment company taxable income generally excludes net unrealized appreciation or depreciation, as investment gains and losses are not included in investment company taxable income until they are realized. Depending on the level of taxable income or capital gains earned in a tax year, we may choose to carry forward taxable income or capital gains in excess of current year distributions into the next year and pay a 4% U.S. federal excise tax on such income. Any such carryover taxable income or capital gains must be distributed through a dividend declared on or prior to the later of (1) the filing of the U.S. federal income tax return for the applicable fiscal year and (2) the fifteenth day of the ninth month following the close of the year in which such taxable income was generated. In lieu of distributing our net capital gains for a year, we may decide to retain some or all of our net capital gains. We will be required to pay a 21% corporate rate U.S. federal income tax on any such retained net capital gains. We may elect to treat such retained capital gain as a deemed distribution to shareholders. Under such circumstances, shareholders will be required to include their share of such retained capital gain in income, but will receive a credit for the amount of U.S. federal income tax paid at corporate rates with respect to their shares. As an investment company that qualifies as a RIC, federal income taxes payable on security gains that we elect to retain are accrued only on the last day of our tax year, December 31. Any net capital gains actually distributed to shareholders and properly reported by us as capital gain dividends are generally taxable to the shareholders as long-term capital gains. See Note 6 for further discussion. The Taxable Subsidiary, a wholly-owned subsidiary of CSWC, is not a RIC and is required to pay taxes at the corporate rate of 21%. For tax purposes, the Taxable Subsidiary has elected to be treated as a taxable entity, and therefore is not consolidated for tax purposes and is taxed at normal corporate tax rates based on taxable income and, as a result of its activities, may generate an income tax provision or benefit. The taxable income, or loss, of the Taxable Subsidiary may differ from its book income, or loss, due to temporary book and tax timing differences and permanent differences. This income tax provision, or benefit, if any, and the related tax assets and liabilities, are reflected in our consolidated financial statements. Management evaluates tax positions taken or expected to be taken in the course of preparing the Company’s consolidated financial statements to determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax positions with respect to tax at the CSWC level not deemed to meet the “more-likely-than-not” threshold would be recorded as an expense in the current year. Management’s conclusions regarding tax positions will be subject to review and may be adjusted at a later date based on factors including, but not limited to, on-going analyses of tax laws, regulations and interpretations thereof. The Company has concluded that it does not have any uncertain tax positions that meet the recognition of measurement criteria of ASC Topic 740, Income Taxes , ("ASC 740") for the current period. Also, we account for interest and, if applicable, penalties for any uncertain tax positions as a component of income tax provision. No interest or penalties expense was recorded during the three and six months ended September 30, 2023 and 2022. Deferred Taxes Deferred tax assets and liabilities are recorded for losses or income at the Taxable Subsidiary using statutory tax rates. A valuation allowance is provided against deferred tax assets when it is more likely than not that some portion or all of the deferred tax asset will not be realized. ASC 740 requires the effects of changes in tax rates and laws on deferred tax balances to be recognized in the period in which the legislation was enacted. See Note 6 for further discussion.
Stock-Based Compensation	Stock-Based Compensation We account for our share-based compensation using the fair value method, as prescribed by ASC Topic 718, Compensation – Stock Compensation . Accordingly, we recognize share-based compensation cost on a straight-line basis for all share-based payments awards granted to employees. For restricted stock awards, we measure the fair value based upon the market price of our common stock on the date of the grant. For restricted stock awards, we amortize this fair value to share-based compensation expense over the vesting term. We recognize forfeitures as they occur. The unvested shares of restricted stock awarded pursuant to CSWC’s equity compensation plans are participating securities and are included in the basic and diluted earnings per share calculation.
Shareholder Distributions	Shareholder Distributions Distributions to common shareholders are recorded on the ex-dividend date. The amount of distributions, if any, is determined by the Board of Directors each quarter and is generally based upon the earnings estimated by management. Net realized capital gains, if any, generally are distributed, although the Company may decide to retain such capital gains for investment.
Presentation	Presentation Presentation of certain amounts in the consolidated financial statements for the prior year comparative consolidated financial statements is updated to conform to the current period presentation.
Recently Issued or Adopted Accounting Standards	Recently Issued or Adopted Accounting Standards In June 2022, the FASB issued ASU 2022-03, “Fair Value Measurement (Topic 820) - Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions,” which was issued to (1) clarify the guidance in Topic 820, Fair Value Measurement, when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of an equity security, (2) amend a related illustrative example, and (3) introduce new disclosure requirements for equity securities subject to contractual sale restrictions that are measured at fair value in accordance with Topic 820. The new guidance is effective for interim and annual periods beginning after December 15, 2023. The Company is currently evaluating the impact of the new standard on the Company's consolidated financial statements

The balance increases with the increase in variability of shares outstanding throughout the year due to share issuance and repurchase activity. 4 The ratios reflect an annualized amount. 5 Total investment return based on purchase of stock at the current market price on the first day and a sale at the current market price on the last day of each period reported on the table and assumes reinvestment of dividends at prices obtained by CSWC’s dividend reinvestment plan during the period. As such, the total investment return is not annualized. The return does not reflect any sales load that may be paid by an investor. 6 Total return based on change in NAV was calculated using the sum of ending NAV plus dividends to shareholders and other non-operating changes during the period, as divided by the beginning NAV, and has not been annualized
