Amortized cost reflects accretion of effective yield less any cash distributions received or entitled to be received from CLO subordinated note investments. CLO subordinated note positions are entitled to recurring distributions, which are generally equal to the residual cash flow of payments received on underlying securities less contractual payments to debt holders and fund expenses. The rate disclosed on subordinated note investments is the estimated effective yield, generally established at purchase, and reevaluated upon the receipt of the initial distribution and each subsequent quarter thereafter. The estimated effective yield is based upon projected amounts and timing of future distributions and the projected amounts and timing of terminal principal payments at the time of estimation. The estimated effective yield and investment cost may ultimately not be realized. Projected cash flows, including the amounts and timing of terminal principal payments, which generally are projected to occur prior to the contractual maturity date, were utilized in deriving the effective yield of the investments.

Loan accumulation facilities are financing structures intended to aggregate loans that are expected to form part of the portfolio of a future CLO vehicle. Reported yields represent an estimated yield to be earned on the investment. Income notes associated with loan accumulation facilities generally pay returns equal to the income earned on facility assets, less costs of debt financing and manager costs and expenses. In January 2023, the Company prospectively adjusted the estimated yield on this position to 0.00% due to an adverse change in estimated cash flows in accordance with ASC 325-40. As of December 31, 2022, the fair value of the loan accumulation facility was determined by a probability weighted net asset value (“NAV”) analysis. Non-qualifying assets under Section 55(a) of the 1940 Act.

Investment was on non-accrual status as of December 31, 2022, meaning the Company suspended recognition of all or a portion of income on the investment. See Note 4 At December 31, 2022, the Company held loans with an aggregate principal amount of $312,595, or 87% of the total loan portfolio, that bore interest at a variable rate indexed to LIBOR (L) or SOFR, and reset monthly, quarterly, or semi-annually. For each variable-rate investment, the Company has provided the spread over the reference rate and current interest rate in effect at December 31, 2022. Unless otherwise noted, all investments with a stated PIK rate require interest payments with the issuance of additional securities as payment of the entire PIK provision. As of December 31, 2022, the effective accretable yield was estimated to be 0%, as the aggregate amount of projected distributions, including projected distributions related to liquidation of the underlying portfolio upon the security's anticipated optional redemption, was less than current amortized cost. Projected distributions are periodically monitored and re-evaluated. All actual distributions were recognized as reductions to amortized cost until such time, if and when occurring, a future aggregate amount of then-projected distributions exceeds the security's then-current amortized cost. The Company holds at least one seat on the portfolio company’s board of directors. As of December 31, 2023, the Company held loans with an aggregate fair value of $230,185, or 92% of the total loan portfolio, that bore interest at a variable rate indexed to LIBOR (L), Prime or SOFR, and reset monthly, quarterly, or semi-annually.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of presentation: The Company prepares its consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”), including ASC Topic 946, Financial Services-Investment Companies , and the reporting requirements for Form 10-K, the 1940 Act, and Articles 6 and 12 of Regulation S-X. The consolidated financial statements include all adjustments, consisting only of normal and recurring accruals and adjustments, necessary for fair presentation in accordance with GAAP. Reclassifications : Certain prior period amounts may have been reclassified to conform to the current period presentation in the consolidated financial statements and the accompanying notes thereto. Reclassifications did not impact net increase (decrease) in net assets resulting from operations, total assets, total liabilities or total net assets, or consolidated statements of changes in net assets and consolidated statements of cash flows classifications. Principles of consolidation: The Company consolidates majority-owned investment company subsidiaries. The Company does not own any controlled operating company whose business consists of providing services to the Company, which would also require consolidation. All intercompany balances and transactions are eliminated upon consolidation. Fair value of financial instruments: The Company applies fair value accounting to all of its financial instruments in accordance with ASC Topic 820, Fair Value Measurements (“ASC Topic 820”), which defines fair value, establishes a framework to measure fair value, and requires disclosures regarding fair value measurements. Fair value is defined as the price to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is determined through the use of models and other valuation techniques, valuation inputs, and assumptions market participants would use to value the financial instrument. Highest priority is given to prices for identical financial instruments quoted in active markets (Level 1) and the lowest priority is given to unobservable valuation inputs (Level 3). The availability of observable inputs can vary significantly and is affected by many factors, including the type of product, whether the product is new to the market, whether the product is traded on an active exchange or in the secondary market, and the current market conditions. To the extent that the valuation is based on unobservable inputs, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for financial instruments classified as Level 3 (i.e., those instruments valued using unobservable inputs), which comprise the majority of the Company’s investments. See Note 5 for details. Changes to the Company’s and OFS Advisor's valuation policies are reviewed and approved by management and the Company’s board of directors (the “Board”). As the Company’s investments change, markets change, new products develop, and valuation inputs become more or less observable, the Company will continue to refine its valuation methodologies. See Note 5 for more detailed disclosures of the Company’s fair value measurements of its financial instruments. Investment classification: The Company classifies its investments in accordance with the 1940 Act. Under the 1940 Act, “Control Investments” are defined as investments in those companies in which the Company owns more than 25% of the voting securities or has rights to maintain greater than 50% of board representation, “Affiliate Investments” are defined as investments in those companies in which the Company owns between 5% and 25% of the voting securities, and “Non-Control/Non-Affiliate Investments” are those that neither qualify as Control Investments nor Affiliate Investments. Significant Subsidiaries : The Company evaluates the issuers of its Control Investments for significance in accordance with Rules 3-09 and 4-08(g) of Regulation S-X. No issuers of Control Investments were considered a significant subsidiary under these rules as of or for the years ended December 31, 2023, 2022 and 2021. Use of estimates: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of investment income, expenses, gains and losses during the reporting period. Actual results could differ significantly from those estimates. Reportable segments: The Company has a single reportable segment and single operating segment structure. Cash: The Company’s cash balances are maintained with a member bank of the Federal Deposit Insurance Corporation (“FDIC”), and at times, such balances exceed the FDIC insurance limits. The Company does not believe its cash balances are exposed to any significant credit risk. As of December 31, 2023 and 2022, cash includes aggregate amounts totaling $45,349 and 14,937, respectively, held in cash and cash equivalent accounts at US Bank N.A. and Citibank N.A. In addition, the Company’s use of cash held by SBIC I LP was limited by SBA regulation and use of cash held by OFSCC-FS is limited by the terms and conditions of the BNP Facility, including but not limited to, the payment of interest expense and principal on the outstanding borrowings. Revenue recognition: Interest income : Interest income from the Company’s loan and CLO debt investments is recognized on an accrual basis and reported as an interest receivable until collected. Interest income is accrued based on the outstanding principal amount on the consolidated schedule of investments and the contractual terms of the debt investment. Certain of the Company’s investments contain a payment-in-kind interest income provision (“PIK interest”). The PIK interest, computed at the contractual rate specified in the applicable investment agreement, is added to the principal balance of the investment, rather than being paid in cash. PIK interest on such investments is generally due at the maturity of the investment. Recognition of cash and PIK interest includes assessments of collectability. The Company discontinues the accrual of interest income, including PIK interest, when there is reasonable doubt that the interest income will be collected. See Non-Accrual Loans section. Loan origination fees, original issue discount (“OID”), market discount or premium, and loan amendment fees (collectively, “Net Loan Fees”) are recorded as an adjustment to the amortized cost of the investment, and accreted or amortized as an adjustment to interest income over the life of the respective debt investment using a method that approximates the effective interest method. When the Company receives a loan principal payment, the unamortized Net Loan Fees related to the paid principal is accelerated and recognized in interest income. The Company may also acquire or receive equity, warrants or other equity-related securities in connection with the Company’s acquisition of, subsequent amendment or restructuring to, debt investments. The Company determines the cost basis of the equity investment based on its relative fair value to the fair value of debt investments and other securities or consideration received. Any resulting difference between the face amount of the debt and its recorded cost resulting from the assignment of value to the equity investment is treated as OID, and accreted into interest income as described above. Interest income - Structured Finance Securities : Structured Finance Securities include CLO mezzanine debt, CLO subordinated notes and loan accumulation facility positions. Interest income from investments in CLO subordinated securities is recognized on the basis of the estimated effective yield to expected redemption utilizing estimated cash flows in accordance with ASC Subtopic 325-40, Beneficial Interests in Securitized Financial Assets . The Company monitors the expected cash flows from its CLO subordinated notes, and the accretable yields are generally established at purchase, and reevaluated upon the receipt of the initial distribution and each subsequent quarter thereafter. Expected cash flows inherent in the Company’s estimates of accretable yields are based on expectations of defaults and loss-on-default severity, as well as other loan-performance assumptions, impacting the loans in the underlying CLO portfolios. These estimated cash flows are subject to a reasonable possibility of near-term change due to economic and credit market conditions, and the effect of these changes could be material. Interest income from investments in loan accumulation facilities is recognized on an accrual basis based on an estimated yield. Income notes associated with loan accumulation facilities generally pay returns equal to the actual income earned on facility assets less costs of senior financing and manager costs. Interest income is generally received upon the earlier of the closing of the CLO securitization or liquidation of the underlying portfolio. The Company periodically evaluates the realizability of such amounts and, if necessary, subsequently adjusts the estimated yield. Dividend income : Dividend income on common equity securities in limited liability companies, partnerships, and other private entities, generally payable in cash, is accrued at the time dividends are declared (in the absence of a formal ex-dividend or record date). Declared dividends payable in cash are reported as dividends receivable until collected. Distributions in excess of current or accumulated net income of the underlying portfolio company are recorded as return of capital and, correspondingly, as a reduction in the cost of the investment. Dividend income on preferred equity investments is accrued based on the contractual terms of the preferred equity investment, subject to assessments of collectability (including fair value coverage). Dividends on preferred equity securities may be payable in cash or in additional preferred securities. Non-cash dividends payable in additional preferred securities (“PIK dividends”) are recorded as an adjustment (i.e., increase) to the cost basis of the investment. The Company discontinues accrual of PIK dividends when there is reasonable doubt that the income will ultimately be collected. Fee income : The Company generates fee revenue in the form of syndication, prepayment, and other contractual fees, that are recognized as the related services are rendered. In the general course of its business, the Company receives certain fees, such as management fees, from portfolio companies which are non-recurring in nature. Prepayment fees are received on certain loans when repaid prior to their scheduled due date, which are recognized as earned when received. Syndication fees are received for capital structuring, loan syndication or advisory services from certain portfolio companies, which are recognized as earned upon closing of the investment. The Company also earns unfunded commitment fees on undrawn revolving lines of credit and delayed draw facility commitments. Investment transactions and net realized and unrealized gains and losses on investments : Investment transactions are reported on a trade-date basis. Unsettled trades as of the statement of assets and liabilities date are included in receivable for investments sold and payable for investments purchased, as applicable. Realized gains or losses on investments are measured by the difference between the net proceeds from the disposition and the amortized cost basis of the investment on the trade date. Investments are valued at fair value in accordance with ASC 820 as determined in good faith by OFS Advisor, as the valuation designee, under the oversight of the Board. The Company reports changes in the fair value of investments, relative to the amortized cost of investments, as net unrealized appreciation (depreciation) on investments in the consolidated statements of operations. Non-accrual loans : Management reviews, for placement on non-accrual status, all loans and CLO mezzanine debt investments that become past due on principal and interest, and/or when there is reasonable doubt that principal or interest will be collected. When a loan is placed on non-accrual status, accrued and unpaid cash interest is reversed. Additionally, Net Loan Fees are no longer recognized as of the date the loan is placed on non-accrual status. Interest payments subsequently received on non-accrual investments may be recognized as income or applied to amortized cost depending upon management’s judgment. Interest accruals and Net Loan Fee amortization are resumed on non-accrual investments only when they are brought current with respect to principal and interest payments and, in the judgment of management, it is probable that the Company will collect all principal and interest from the investment. See Note 4 for further information on loans on non-accrual status as of December 31, 2023 and December 31, 2022. Income taxes: The Company has elected to be treated, and intends to qualify annually, as a RIC under Subchapter M of the Code. To qualify as a RIC, the Company must, among other things, meet certain source of income and asset diversification requirements, and timely distribute at least 90% of its investment company taxable income (“ICTI”) annually to its stockholders. The Company has made, and intends to continue to make, requisite distributions to its stockholders, which generally relieves the Company from U.S. federal income taxes. Depending on the level of ICTI earned in a tax year, the Company may choose to retain ICTI in an amount less than that which would trigger U.S. federal income tax liability under Subchapter M of the Code. However, the Company would be liable for a 4% excise tax on such undistributed income. Such spillover income increases the Company’s RIC distribution requirement in the following year. An excise tax liability is recognized when the Company determines its estimated current year annual ICTI, capital gain net income, and any undistributed ICTI and capital gain net income from the prior year, as defined in the Code, exceeds distributions paid during the calendar year. For the years ended December 31, 2023, 2022 and 2021, the Company accrued U.S. federal excise taxes of $0, $100 and $0, respectively. The Company may utilize OFSCC-MB when making equity investments in portfolio companies taxed as pass-through entities to meet its source-of-income requirements as a RIC. For U.S. federal income tax purposes, OFSCC-MB is not consolidated with the RIC and is taxed as a C-Corporation. See Note 8 for further information. The Company evaluates tax positions taken in the course of preparing its tax returns to determine whether they are “more-likely-than-not” to be sustained by the applicable tax authority. Tax benefits of positions not deemed to meet the more-likely-than-not threshold could result in greater and undistributed ICTI, income and excise tax expense, and, if involving multiple years, a re-assessment of the Company’s RIC status. GAAP requires recognition of accrued interest and penalties related to uncertain tax benefits as income tax expense. There were no uncertain income tax positions at December 31, 2023, 2022 and 2021. The current and prior three tax years remain subject to examination by U.S. federal and most state tax authorities. Distributions: Distributions to common stockholders are recognized on the record date. The timing of distributions as well as the amount to be paid out as a distribution is determined by the Board each quarter. Distributions from net investment income and net realized gains are determined in accordance with the Code. Net realized capital gains, if any, are distributed at least annually, although the Company may decide to retain such capital gains for investment. Distributions paid in excess of current and accumulated ICTI and not capital gains are considered returns of capital to stockholders. The Company has adopted a dividend reinvestment plan (“DRIP”) that provides for reinvestment of any distributions the Company declares in cash on behalf of its stockholders, unless a stockholder elects to receive cash. As a result, if the Board authorizes and the Company declares a cash distribution, then stockholders who have not “opted out” of the DRIP will have their cash distribution automatically reinvested in additional shares of the Company’s common stock, rather than receiving the cash distribution. The Company may use newly issued shares under the guidelines of the DRIP, or the Company may purchase shares in the open market in connection with its obligations under the plan. Deferred debt issuance costs: Deferred debt issuance costs represent fees and other direct incremental costs incurred in connection with the Company’s borrowings. Deferred debt issuance costs are presented as a direct reduction of the related debt liability on the consolidated statements of assets and liabilities, except for deferred debt issuance costs associated with the Company’s revolving line of credit arrangements, which are included in prepaid expenses and other assets on the consolidated statements of assets and liabilities. Unamortized deferred debt issuance costs included in prepaid expenses and other assets on the consolidated statements of assets and liabilities as of December 31, 2023 and 2022, were $1,062 and $1,316, respectively. Deferred debt issuance costs are amortized to interest expense over the term or expected term of the related debt. Intangible asset: On December 4, 2013, in connection with the SBIC Acquisition, the Company recorded an intangible asset of $2,500 attributable to the SBIC license. The Company amortizes the intangible asset on a straight-line basis over its estimated useful life. During the first quarter of 2022, the Company changed its estimate of the useful life to terminate on March 1, 2024, due to early redemptions of SBA debentures. The Company recognized amortization of $408, $409 and $222 for the years ended December 31, 2023, 2022, and 2021, respectively. The Company tests its intangible asset for impairment if events or circumstances suggest that the asset carrying value may not be fully recoverable. The carrying value of the intangible asset, net of accumulated amortization, was $69 and $477 at December 31, 2023 and 2022, respectively, is included in prepaid expenses and other assets in the consolidated statements of assets and liabilities. Interest expense: Contractual interest expense on the Company’s borrowings is recognized on an accrual basis as incurred. See Note 7 for further information. Concentration of credit risk: Aside from the Company’s investments, financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash deposits at financial institutions. At various times during the year, the Company exceeds the federally insured limits. The Company places cash deposits only with high credit quality institutions which OFS Advisor believes will mitigate the risk of loss due to credit risk. If borrowers completely fail to perform according to the terms of the contracts, the amount of loss due to credit risk from the Company’s investments is equal to the Company’s recorded investment and the unfunded commitments disclosed in Note 6 . New Accounting Pronouncements and Rule Issuances In June 2022, the FASB issued Fair Value Measurement (Topic 820), Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions (“ASU 2022-03”). ASU 2022-03 clarifies guidance for fair value measurement of an equity security subject to a contractual sale restriction and establishes new disclosure requirements for such equity securities. ASU 2022-03 is effective for fiscal years beginning after December 15, 2023 and for interim periods within those fiscal years, with early adoption permitted. The Company has concluded that this guidance will not have a material impact on its consolidated financial statements. In December 2023, the FASB issued Income Taxes (Topic 740), Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 amend Topic 740 to, among other things, require on an annual basis, the disclosure of additional income tax information related to the Company’s effective tax rate reconciliation and income taxes paid. ASU 2023-09 is intended to enhance the transparency by providing more detailed income tax disclosures that would be useful in making capital allocation decisions. ASU 2023-09 amendments are effective for annual periods beginning after December 15, 2024. The Company is currently evaluating the impact, if any, ASU 2023-09 will have on its consolidated financial statements.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Investment Advisory and Management Agreement: OFS Advisor manages the day-to-day operations of, and provides investment advisory services to, the Company pursuant to an agreement dated November 7, 2012 (“Investment Advisory Agreement”). The Investment Advisory Agreement was most recently re-approved on April 5, 2023. Under the terms of the Investment Advisory Agreement, which are in accordance with the 1940 Act and subject to the overall supervision of the Board, OFS Advisor is responsible for sourcing potential investments, conducting research and diligence on potential investments and equity sponsors, analyzing investment opportunities, structuring investments, and monitoring investments and portfolio companies on an ongoing basis. OFS Advisor is a wholly owned subsidiary of OFSAM and a registered investment advisor under the Investment Advisers Act of 1940, as amended. OFS Advisor’s services under the Investment Advisory Agreement are not exclusive to the Company and OFS Advisor is free to furnish similar services to other entities, including other BDCs affiliated with OFS Advisor, so long as its services to the Company are not impaired. OFS Advisor also serves as the investment adviser or sub-adviser to various clients, including HPCI and OCCI. OFS Advisor receives fees for providing services, consisting of two components: a base management fee and an incentive fee. The base management fee is calculated at an annual rate of 1.75% and based on the average value of the Company’s total assets (other than cash and cash equivalents but including assets purchased with borrowed amounts and including assets owned by any consolidated entity) at the end of the two most recently completed calendar quarters, adjusted for any share issuances or repurchases during the quarter. For the years ended December 31, 2023, 2022 and 2021, OFS Advisor agreed to reduce its base management fee attributable to all assets held through OFSCC-FS (“OFSCC-FS Assets”) to 0.25% per quarter (1.00% annualized) of the average value of the OFSCC-FS Assets (other than cash and cash equivalents but including assets purchased with borrowed amounts) at the end of the two most recently completed calendar quarters. OFS Advisor’s base management fee reduction is renewable on an annual basis and OFS Advisor is not entitled to recoup the amount of the base management fee reduced with respect to the OFSCC-FS Assets. OFS Advisor most recently renewed the agreement to reduce its base management fee for the 2024 calendar year on January 8, 2024. The incentive fee has two parts. The first part of the incentive fee (“Income Incentive Fee”) is calculated and payable quarterly in arrears based on the Company’s pre-incentive fee net investment income for the immediately preceding calendar quarter. For this purpose, pre-incentive fee net investment income means interest income, dividend income and any other income (including any other fees such as commitment, origination and sourcing, structuring, diligence and consulting fees or other fees that the Company receives from portfolio companies but excluding fees for providing managerial assistance) accrued during the calendar quarter, minus operating expenses for the quarter (including the base management fee, any expenses payable under the Administration Agreement (as defined below) and any interest expense and dividends paid on any outstanding preferred stock, but excluding the incentive fee). Pre-incentive fee net investment income includes, in the case of investments with a deferred interest or dividend feature (such as OID, debt instruments with PIK interest, equity investments with accruing or PIK dividend and zero coupon securities), accrued income that the Company has not yet received in cash. Pre-incentive fee net investment income is expressed as a rate of return on the value of the Company’s net assets (defined as total assets less indebtedness and before taking into account any incentive fees payable during the period) at the end of the immediately preceding calendar quarter and adjusted for any share issuances or repurchases during such quarter. The incentive fee with respect to pre-incentive fee net income is 20.0% of the amount, if any, by which the pre-incentive fee net investment income for the immediately preceding calendar quarter exceeds a 2.0% hurdle rate (which is 8.0% annualized) and a “catch-up” provision measured as of the end of each calendar quarter. Under this provision, in any calendar quarter, OFS Advisor receives no incentive fee until the net investment income equals the hurdle rate of 2.0%, but then receives, as a “catch-up,” 100.0% of the pre-incentive fee net investment income with respect to that portion of such pre-incentive fee net investment income, if any, that exceeds the hurdle rate but is less than 2.5%. The effect of this provision is that, if pre-incentive fee net investment income exceeds 2.5% in any calendar quarter, OFS Advisor will receive 20.0% of the pre-incentive fee net investment income. Pre-incentive fee net investment income does not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation. Because of the structure of the incentive fee, it is possible that the Company may pay an incentive fee in a quarter in which the Company incurs a loss. For example, if the Company receives pre-incentive fee net investment income in excess of the quarterly minimum hurdle rate, the Company will pay the applicable incentive fee even if the Company has incurred a loss in that quarter due to realized and unrealized capital losses. The Company’s net investment income used to calculate this part of the incentive fee is also included in the amount of the Company’s gross assets used to calculate the base management fee. These calculations are appropriately prorated for any period of less than three months. The second part of the incentive fee (the “Capital Gains Fee”) is determined and payable in arrears as of the end of each calendar year (or upon termination of the Investment Advisory Agreement, as of the termination date), commencing on December 31, 2012, and equals 20.0% of the Company’s aggregate realized capital gains, if any, on a cumulative basis from the date of the election to be a BDC through the end of each calendar year, computed net of all realized capital losses, losses on extinguishment of debt, income taxes from realized capital gains and unrealized capital depreciation through the end of such year, less all previous amounts paid in respect of the Capital Gains Fee; provided that the incentive fee determined as of December 31, 2012, was calculated for a period of shorter than twelve calendar months to take into account any realized capital gains computed net of all realized capital losses and unrealized capital depreciation for the period beginning on the date of the Company’s election to be a BDC and ending December 31, 2012. The Company accrues the Capital Gains Fee if, on a cumulative basis, the sum of net realized capital gains (losses) plus net unrealized appreciation (depreciation) is positive. An accrued Capital Gains Fee relating to net unrealized appreciation is deferred, and not due to OFS Advisor, until the close of the year in which such gains are realized. If, on a cumulative basis, the sum of net realized capital gains (losses) plus net unrealized appreciation (depreciation) decreases during a period, the Company will reverse any excess Capital Gains Fee previously accrued such that the amount of Capital Gains Fee accrued is no more than 20% of the sum of net realized capital gains (losses) plus net unrealized appreciation (depreciation). License Agreement: The Company entered into a license agreement with OFSAM under which OFSAM has agreed to grant the Company a non-exclusive, royalty-free license to use the name “OFS.” Administration Agreement: OFS Services furnishes the Company with office facilities and equipment, necessary software licenses and subscriptions, and clerical, bookkeeping and record keeping services at such facilities pursuant to an Administration Agreement. The Administration Agreement was most recently re-approved by the Board on April 5, 2023. Under the Administration Agreement, OFS Services performs, or oversees the performance of, the Company’s required administrative services, which include being responsible for the financial records that the Company is required to maintain and preparing reports to its stockholders and all other reports and materials required to be filed with the SEC or any other regulatory authority. In addition, OFS Services assists the Company in determining and publishing its net asset value, oversees the preparation and filing of its tax returns and the printing and dissemination of reports to its stockholders, and generally oversees the payment of the Company’s expenses and the performance of administrative and professional services rendered to the Company by others. Under the Administration Agreement, OFS Services also provides managerial assistance on the Company’s behalf to those portfolio companies that have accepted the Company’s offer to provide such assistance. Payment under the Administration Agreement is equal to an amount based upon the Company’s allocable portion of OFS Services’s overhead in performing its obligations under the Administration Agreement, including, but not limited to, rent, information technology services and the Company’s allocable portion of the cost of its officers, including its chief executive officer, chief financial officer, chief compliance officer, chief accounting officer, and their respective staffs. To the extent that OFS Services outsources any of its functions, the Company will pay the fees associated with such functions on a direct basis without profit to OFS Services. Equity Ownership: As of December 31, 2023, affiliates of OFS Advisor held 3,022,184 shares of common stock, which is approximately 23% of the Company's outstanding shares of common stock. Expenses recognized under agreements with OFS Advisor and OFS Services and distributions paid to affiliates for the years ended December 31, 2023, 2022 and 2021 are presented below: December 31, 2023 2022 2021 Base management fees $ 7,218 $ 7,979 $ 7,669 Incentive fees: Income Incentive Fee 5,040 2,276 2,352 Capital Gains Fee (1) — (1,916) 1,916 Administration fees 1,680 1,742 1,758 Distributions paid to affiliates 4,049 3,503 2,764 (1) As of December 31, 2021, the Capital Gains Fee of $1,916 was accrued in accordance with GAAP, inclusive of net unrealized appreciation as of the determination date. The Capital Gains Fee payable to the Advisor under the Investment Advisory Agreement does not include net unrealized appreciation, and accordingly no amount was payable or due to the Advisor as of December 31, 2021. During the year ended December 31, 2022, the Company reversed the previously accrued Capital Gains Fees of $1,916 due to a reduction in net unrealized appreciation on the investment portfolio.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	12 Months Ended
	Dec. 31, 2023
Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments Investments The Company’s investments are carried at fair value and determined in accordance with ASC 820 and a documented valuation policy that is applied in a consistent manner. On September 7, 2022, pursuant to Rule 2a-5 of the 1940 Act (“Rule 2a-5”), the Board designated OFS Advisor as the valuation designee to perform fair value determinations relating to the Company’s investments, commencing with the quarter ended September 30, 2022, and the Board maintains oversight of OFS Advisor in its capacity as valuation designee, as prescribed in Rule 2a-5. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair values are determined with models or other valuation techniques, valuation inputs, and assumptions that market participants would use in pricing an asset or liability. Valuation inputs are organized in a hierarchy that gives the highest priority to prices for identical assets or liabilities quoted in active markets (Level 1) and the lowest priority to fair values based on unobservable inputs (Level 3). The three levels of inputs in the fair value hierarchy are described below: Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity can access at the measurement date. Level 2: Inputs other than quoted prices within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3: Unobservable inputs for the asset or liability, and situations where there is little, if any, market activity for the asset or liability at the measurement date. The inputs into the determination of fair value are based upon the best information under the circumstances and may require management to exercise significant judgment or estimation. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the investment. The Company generally categorizes its investment portfolio into Level 3, and to a lesser extent Level 2, of the hierarchy. The Company assesses the levels of the investments at each measurement date, and transfers between levels are recognized on the measurement date. The following table presents the Company’s transfers of Level 2 and Level 3 debt investments for the years ended December 31, 2023 and 2022, respectively: Year Ended December 31, 2023 2022 Transfers from Level 2 to Level 3 $ — $ 3,218 Transfers from Level 3 to Level 2 1,616 — Certain of the Company’s investments are exchanged in the non-public market among banks, CLOs and other institutional investors for loans to large U.S. corporations. The Company classifies these loan investments as Level 2 when a sufficient number of market quotations or indicative prices from pricing services or broker/dealers (collectively, “Indicative Prices”) are available, and the depth of the market is sufficient, in management's judgment, to transact at those prices in amounts approximating the Company’s investment position at the measurement date. Investments for which sufficient Indicative Prices exist are generally valued consistent with such Indicative Prices. In addition, each quarter, the Company assesses whether an arm’s length transaction occurred in the same security, including the Company’s new investments during the quarter, the cost of which (“Transaction Prices”), may be considered a reasonable indication of fair value for a period of time, generally up to three months after the transaction date or until the initial payment date, in the case of new issue Structured Finance Securities. Portfolio investments with a fair value of $22,874 and $0, respectively, were valued at their Transaction Prices at December 31, 2023 and December 31, 2022. Investments that are not valued using Indicative Prices or Transaction Prices are typically valued using two different valuation techniques. The Company typically estimates the fair value of debt investments by a discounted cash flows technique in which a current price is imputed for the investment based upon an assessment of the expected market yield (or discount rate) for similarly structured investments with a similar level of risk. The Company considers the current contractual interest rate, the maturity and other terms of the investment relative to risk of the portfolio company and various market indices. A key determinant of portfolio-company risk is the leverage through the investment relative to earnings metrics of the portfolio company. The fair value of Structured Finance Securities are also estimated primarily by discounted cash flow techniques. In valuing such investments, the Company considers CLO performance metrics, including prepayment rates, default rates, loss-on-default and recovery rates, and other metrics, as well as estimated market yields provided by a recognized industry pricing service as a primary source for discounted cash flow fair value estimates, supplemented by actual trades executed in the market at or around period-end, as well as the Indicative Prices provided by broker-dealers in its estimate of the fair value of such investments. The Company also considers the operating metrics, typically included in the governing documents of CLO vehicles, including collateralization tests, concentration limits, defaults, restructuring activity and prepayment rates on the underlying loans, if applicable. The fair value of the Company’s equity investments, as well as certain of its impaired debt investments, are generally estimated through analysis of the portfolio company's enterprise value under a market approach. Enterprise value means the entire value of the portfolio company to a market participant, including the sum of the values of debt and equity securities used to capitalize the enterprise at a point in time. The primary method for determining enterprise value under the market approach involves a multiple analysis, whereby appropriate multiples are applied to an earnings metric of the portfolio company, typically earnings before net interest expense, income tax expense, depreciation and amortization (“EBITDA”) or revenue. EBITDA and revenue multiples are typically determined based upon review of market comparable transactions and publicly traded comparable companies, if any. The Company may also utilize other portfolio-company earnings metrics to determine enterprise value, such as forecast EBITDA or revenue, or a weighting of multiple factors. At times, the Company may also use a discounted cash flow technique to value its equity securities. Application of these valuation methodologies involves a significant degree of judgment by management. Due to the inherent uncertainty of determining the fair value of Level 3 investments, the fair value of the investments may differ significantly from the values that would have been used had a ready market or observable inputs existed for such investments and may differ materially from the values that may ultimately be received or settled. Further, such investments are generally subject to legal and other restrictions, or otherwise are less liquid than publicly traded instruments. If the Company were required to liquidate a portfolio investment in a forced or liquidation sale, the Company might realize significantly less than the value at which such investment had previously been recorded and incur a realized capital loss. The Company’s investments are subject to market risk as a result of economic and political developments, including impacts from elevated interest and inflation rates, the ongoing war between Russia and Ukraine, the escalated armed conflict in the Middle East, instability in the U.S. and international banking systems, the risk of recession or a shutdown of U.S government services and related market volatility. Market risk is directly impacted by the volatility and liquidity in the markets in which certain investments are traded and can affect the fair value of the Company’s investments. The Company’s investments are also subject to interest rate risk. Changes in interest rates, including any potential interest rate reductions approved by the U.S. Federal Reserve, may impact both our cost of funding and the valuation of our investment portfolio. The following tables present the Company’s investment portfolio measured at fair value on a recurring basis as of December 31, 2023 and 2022, respectively.

The Company may make changes to the valuation techniques, among techniques otherwise commonly used in accordance with its valuation policies, and/or the weighting of techniques used for particular investments based on changes in facts-and-circumstances and depending on the availability of, or changes in, information in order to produce the best estimate of fair value as of the measurement date. In addition to the techniques and unobservable inputs noted in the tables below and in accordance with OFS Advisor’s valuation policy, OFS Advisor, as valuation designee, may also use other valuation techniques and methodologies when determining the fair value measurements of the Company’s investment assets.

(2) NAV liquidation represents the fair value, or estimated expected residual value, of the investment. Changes in market credit spreads or events impacting the credit quality of the underlying portfolio company (both of which could impact the discount rate), as well as changes in enterprise value and/or EBITDA multiples, among other things, could have a significant impact on fair values, with the fair value of a particular debt investment susceptible to change in inverse relation to the changes in the discount rate. Changes in enterprise value and/or EBITDA multiples, as well as changes in the discount rate, could have a significant impact on fair values, with the fair value of an equity investment susceptible to change in tandem with the changes in enterprise value and/or EBITDA multiples, and in inverse relation to changes in the discount rate. Due to wide range of approaches towards developing input assumptions to these valuation techniques and the degree of subjectivity used in making the estimates, comparisons between the Company’s disclosures and those of other companies may not be meaningful.

The Company believes that the carrying amounts of its other financial instruments such as cash, receivables and payables approximate the fair value of such items due to the short maturity of such financial instruments. The senior secured revolving credit facility between the Company and Banc of California (formally known as Pacific Western Bank), as lender (“Banc of California Credit Facility”) and the secured revolving credit facility that provides for borrowings in an aggregate principal amount up to $150,000 issued pursuant to a Revolving Credit and Security Agreement by and among OFSCC-FS, the lenders from time to time parties thereto, BNP Paribas, as administrative agent, OFSCC-FS Holdings, LLC, a wholly owned subsidiary of the Company, as equity holder, the Company, as servicer, Citibank, N.A., as collateral agent and Virtus Group, LP, as collateral administrator (“BNP Facility”) are variable rate instruments and fair value is approximately book value.

Debt Disclosure [Abstract]
Borrowings	Borrowings SBA Debentures: The SBIC Program enabled SBIC I LP to obtain leverage by issuing SBA-guaranteed debentures, subject to issuance of a capital commitment by the SBA and customary procedures. These debentures were non-recourse to the Company, had a ten-year maturity and a fixed interest rate at a market-driven spread over ten-year U.S. Treasury Notes. Effective November 26, 2013, the Company received exemptive relief from the SEC to exclude SBA guaranteed debentures from the definition of senior securities in the statutory asset coverage ratio under the 1940 Act, allowing for greater capital deployment. During the year ended December 31, 2023, SBIC I LP redeemed $19,000 of SBA debentures that were contractually due March 1, 2025. The Company recognized a loss on extinguishment of debt of $213 related to the acceleration of unamortized deferred borrowing costs and prepaid (or breakage) interest on the redeemed debentures. As of December 31, 2023 and 2022, SBIC I LP had outstanding SBA debentures of $31,920 and $50,920, respectively. See Note 12 for additional information concerning the Company’s outstanding SBA debentures. On a stand-alone basis, SBIC I LP held $149,698 and $176,521 in assets at December 31, 2023 and 2022, respectively, which accounted for approximately 32% and 34% of the Company’s total consolidated assets, respectively. The following table shows the Company’s outstanding SBA debentures payable as of December 31, 2023 and 2022: Fixed Interest Rate SBA debentures outstanding Pooling Date Maturity Date December 31, 2023 December 31, 2022 March 25, 2015 March 1, 2025 2.872 % $ 31,920 $ 50,920 SBA debentures outstanding 31,920 50,920 Unamortized debt issuance costs (20) (223) SBA debentures outstanding, net of unamortized deferred debt issuance costs $ 31,900 $ 50,697 For the years ended December 31, 2023, 2022 and 2021, the components of interest expense, cash paid for interest, effective interest rates and average outstanding balances for the SBA debentures were as follows: Year Ended December 31, 2023 2022 2021 Stated interest expense $ 1,236 $ 1,552 $ 2,627 Amortization of debt issuance costs 162 188 209 Total interest and debt financing costs $ 1,398 $ 1,740 $ 2,836 Cash paid for interest expense $ 1,418 $ 1,739 $ 2,978 Effective interest rate 3.25 % 3.22 % 3.27 % Average outstanding balance $ 43,046 $ 53,991 $ 86,710 Unsecured Notes: The Outstanding Unsecured Notes totaled $180,000 and $180,000 in aggregate principal debt at December 31, 2023 and 2022, respectively. During the years ended December 31, 2023 and 2022, the Company did not issue, redeem or repurchase any Unsecured Notes. Issuances during the year ended December 31, 2021 On February 10, 2021, the Company closed the public offering of $100,000 aggregate principal amount of its 4.75% notes due 2026, and on March 18, 2021, the Company closed an additional public offering of $25,000 aggregate principal amount of its 4.75% notes due 2026 (the “Unsecured Notes Due February 2026”). The total net proceeds to the Company from the Unsecured Notes Due February 2026, after deducting underwriting fees and offering expenses of $3,936, was approximately $121,064. On October 28, 2021 and November 1, 2021, the Company closed the public offering of $55,000 aggregate principal amount of its 4.95% notes due 2028 (the “Unsecured Notes Due October 2028”), which included a full exercise of the underwriters overallotment option. The total net proceeds to the Company, after deducting underwriting discounts and offering expenses of $1,389, was approximately $53,611. Redemptions during the year ended December 31, 2021 On March 12, 2021, the Company redeemed all of its $50,000 aggregate principal amount of 6.375% notes due April 30, 2025 (the “Unsecured Notes Due April 2025”) and $48,525 aggregate principal amount of 6.50% notes due October 30, 2025 (the “Unsecured Notes Due October 2025”). On November 1, 2021, the Company redeemed all of its $25,000 aggregate principal amount of 6.25% notes due September 30, 2023 (“Unsecured Notes Due September 2023”). On November 22, 2021, the Company redeemed all of its $54,325 aggregate principal amount of 5.95% notes due October 31, 2026 (the “Unsecured Notes Due October 2026”). During the year ended December 31, 2021, the Company recognized a loss on extinguishment of $4,267 related to the acceleration of unamortized deferred borrowing costs on the redemption of unsecured notes. The Unsecured Notes Due February 2026 and the Unsecured Notes Due October 2028 (together, the “Outstanding Unsecured Notes”), were outstanding at December 31, 2023 and are direct unsecured obligations and rank equal in right of payment with all current and future unsecured indebtedness of the Company. Because the Outstanding Unsecured Notes are not secured by any of the Company’s assets, they are effectively subordinated to all existing and future secured unsubordinated indebtedness (or any indebtedness that is initially unsecured as to which the Company subsequently grant a security interest), to the extent of the value of the assets securing such indebtedness, including, without limitation, borrowings under the Banc of California Credit Facility and BNP Facility. The indenture governing the Outstanding Unsecured Notes contains certain covenants: (i) prohibiting additional borrowings, including through the issuance of additional debt securities, unless the Company's asset coverage, as defined in the 1940 Act, after giving effect to any exemptive relief granted to the Company by the SEC, equals at least 150% after such borrowings; and (ii) prohibiting (a) the declaration of any cash dividend or distribution upon any class of the Company’s capital stock (except to the extent necessary for the Company to maintain its treatment as a RIC under Subchapter M of the Code), or (b) the purchase of any capital stock if the Company’s asset coverage, as defined in the 1940 Act, were below 150% at the time of such capital transaction and after deducting the amount of such transaction. For the years ended December 31, 2023, 2022 and 2021, the components of interest expense, cash paid for interest, effective interest rates and average outstanding balances for the Outstanding Unsecured Notes were as follows: Year Ended December 31, 2023 2022 2021 Stated interest expense $ 8,660 $ 8,663 $ 11,160 Amortization of debt issuance costs 981 1,029 1,403 Total interest and debt financing costs $ 9,641 $ 9,692 $ 12,563 Cash paid for interest expense $ 8,660 $ 8,683 $ 10,384 Effective interest rate 5.36 % 5.38 % 6.03 % Average outstanding balance $ 180,000 $ 180,000 $ 208,240 As of December 31, 2023, the Outstanding Unsecured Notes had the following terms and balances: Unsecured Notes Principal Unamortized Discount and Issuance Costs Stated Interest Rate (1) Effective Interest Rate (2) Maturity (3) Unsecured Notes Due February 2026 $ 125,000 $ 1,678 4.75 % 5.39 % February 10, 2026 Unsecured Notes Due October 2028 55,000 989 4.95 % 5.32 % October 31, 2028 Total $ 180,000 $ 2,667 (1) The weighted-average fixed cash interest rate on the Unsecured Notes as of December 31, 2023 was 4.81%. (2) The effective interest rate on the Unsecured Notes includes deferred debt issuance cost amortization. (3) The Company may redeem the Unsecured Notes Due February 2026 in whole or in part at any time, or from time to time, at its option at par plus a “make-whole” premium, if applicable. The Company may redeem the Unsecured Notes Due October 2028 in whole or in part at any time, or from time to time.

Federal Income Tax

Federal Income Tax	12 Months Ended

Income Tax Disclosure [Abstract]
Federal Income Tax	Federal Income Tax Filing status: The Company has elected to be taxed as a RIC under Subchapter M of the Code. In order to maintain its status as a RIC, the Company is required to distribute annually to its stockholders at least 90% of its ICTI, as defined by the Code. Additionally, to avoid a 4% U.S. federal excise tax on undistributed earnings the Company is required to distribute each calendar year the sum of (i) 98% of its ordinary income for such calendar year, (ii) 98.2% of its net capital gains for the one-year period ending October 31 of that calendar year, and (iii) any income recognized, but not distributed, in preceding years and on which the Company paid no U.S. federal income tax. Maintenance of the Company's RIC status also requires adherence to certain source of income and asset diversification requirements. OFSCC-MB, an entity taxed as a corporation under Subchapter C of the Code, is consolidated in the Company’s GAAP financial statements but is not included in the determination of ICTI or the RIC compliance requirements of the Company. The income of OFSCC-MB, net of applicable income taxes, is not included in the Company’s ICTI until distributed by OFSCC-MB, which may result in timing and character differences between the Company’s GAAP and tax-basis net investment income and realized gains and losses. Taxable income and distributions: As of December 31, 2023, the Company met the source of income and asset diversification requirements, and intends to continue to meet these requirements. For the year ended December 31, 2023, the Company had no net accrued excise tax expense related to estimated undistributed income; however, as of December 31, 2023, the Company had an accrued liability for estimated excise taxes of $100. The Company’s ICTI differs from the net increase (decrease) in net assets resulting from operations primarily due to differences in income recognition on the unrealized appreciation/depreciation of investments, income recognition for CLO subordinated note investments, income from Company’s equity investments in pass-through entities, capital gains and losses and the net creation or utilization of capital loss carryforwards. The distributions paid to stockholders are reported as ordinary income, long-term capital gains and returns of capital. The tax character of distributions paid (1) were as follows: Year Ended December 31, 2023 (1) 2022 2021 Ordinary taxable income $ 17,954 $ 15,564 $ 12,207 Long-term capital gain — — — Return of capital — — — Total distributions to common stockholders $ 17,954 $ 15,564 $ 12,207 (1) The calculation of 2023 U.S. federal taxable income is based on certain estimated amounts, including information received from third parties and, as a result, actual 2023 U.S. federal taxable income will not be finally determined until the Company’s 2023 U.S. federal tax return is filed in 2024 (and, therefore, such estimate is subject to change). Tax-basis components of distributable earnings (accumulated losses) as of December 31, 2023 and 2022, were as follows: December 31, 2023 2022 Ordinary income (RIC) $ 3,468 $ 3,551 Undistributed earnings and profits (OFSCC-MB; C-Corporation) 2,075 2,606 Net operating loss carryforward (OFSCC-MB; C-Corporation) 140 — Capital loss carryforwards: RIC – short-term, non-expiring (5,109) (3,683) RIC – long-term, non-expiring (44,664) (34,335) The Company records reclassifications to its capital accounts related to permanent differences between GAAP and tax treatment of excise taxes and other permanent differences. The Company recorded reclassifications to decrease additional paid-in capital against total distributable earnings (accumulated loss) o f $0, $101 and $2,142 for the years ended December 31, 2023, 2022 and 2021, respectively. These reclassifications have no effect on total net assets or net asset value per common share. The estimated tax-basis cost of investments and associated tax-basis gross unrealized appreciation (depreciation) inherent in the fair value of investments as of December 31, 2023 and 2022, were as follows: December 31, 2023 2022 Tax-basis amortized cost of investments $ 399,056 $ 473,716 Tax-basis gross unrealized appreciation on investments 83,007 92,230 Tax-basis gross unrealized depreciation on investments (61,776) (65,370) Tax-basis net unrealized appreciation on investments 21,231 26,860 Fair value of investments $ 420,287 $ 500,576 Deferred taxes: The Company recognizes deferred taxes on the unrealized appreciation or depreciation of securities held through OFSCC-MB and other basis differences, including available loss carry forwards and suspended interest expense deductions reported by portfolio companies. Deferred tax assets and liabilities are measured using enacted corporate federal tax rates and estimated state tax burdens expected to apply to taxable income in the years in which those unrealized gains and losses are realized. The recoverability of deferred tax assets is assessed and a valuation allowance is recorded to the extent that it is more likely than not that any portion of the deferred tax asset will not be realized on the basis of the projected taxable income or other taxable events in OFSCC-MB. The tax-basis unrealized appreciation (depreciation) of investments by tax entity inherent in the fair value of investments as of December 31, 2023 and 2022, were as follows: December 31, 2023 2022 Total net unrealized appreciation on investments held by RIC entities $ 21,453 $ 27,494 OFSCC-MB (C-Corp): Gross unrealized appreciation on investments 1,180 144 Gross unrealized depreciation on investments (1,402) (778) Total net unrealized depreciation on investments on investments held by OFSCC-MB (222) (634) Total tax-basis net unrealized appreciation on investments $ 21,231 $ 26,860 Deferred tax assets and liabilities as of December 31, 2023 and 2022, were as follows: December 31, 2023 2022 Total deferred tax assets $ 328 $ 205 Valuation allowance on deferred tax assets — (124) Total deferred tax liabilities (397) (81) Deferred tax liabilities and assets with tax basis unrealized gain and losses differs from the amount that would have resulted from applying the federal rate of 21% to unrealized gains and losses because of state income taxes, net of associated federal benefit.

Equity [Abstract]
Capital Transactions	Capital Transactions Distributions: The Company intends to make quarterly distributions to stockholders that represent, over time, substantially all of its net investment income. In addition, although the Company may distribute at least annually net realized capital gains, net of taxes if any, out of assets legally available for such distribution, the Company may also retain such capital gains for investment through a deemed distribution. If the Company makes a deemed distribution, stockholders will be treated for U.S. federal income tax purposes as if they had received an actual distribution of the capital gains, net of taxes. The Company may be limited in its ability to make distributions due to the BDC asset coverage requirements of the 1940 Act. In addition, distributions from OFSCC-FS to the Company are restricted by the terms and conditions of the BNP Facility. At December 31, 2023 and December 31, 2022, OFSCC-FS had cash of $3,973 and $3,706, respectively, of which $0 and $0 were available for distribution to the Company at December 31, 2023 and 2022, respectively.

Fee Table [Abstract]
Shareholder Transaction Expenses [Table Text Block]									Stockholder transaction expenses : Sales load borne by us (as a percentage of offering price) — % (1) Offering expenses borne by us (as a percentage of offering price) — % (1) Dividend reinvestment plan fees (per sales transaction fee) $15.00 (2) Total Stockholder transaction expenses (as a percentage of offering price) — % (1) Annual expenses (as a percentage of net assets attributable to common stock) : Base management fees payable under the Investment Advisory Agreement 5.21 % (3) Incentive fees payable under the Investment Advisory Agreement 3.11 % (4) Interest payments on borrowed funds 12.03 % (5) Other expenses 3.11 % (6) Total annual expenses, before base management fee reduction 23.46 % Base management fee reduction (0.75) % (8) Total annual expenses, net of base management fee reduction 22.71 % (7) (1) The amounts set forth in this table do not reflect the impact of any sales load, sales commission or other offering expenses borne by the Company and its stockholders. If applicable, the prospectus or prospectus supplement relating to an offering of our common stock will disclose the offering price and the estimated offering expenses and total stockholder transaction expenses borne by the Company and its common stockholders as a percentage of the offering price. In the event that shares of our common stock are sold to or through underwriters, the applicable prospectus or prospectus supplement will also disclose the applicable sales load and the “Example” will be updated accordingly. (2) The expenses of the DRIP are included in “other expenses.” The plan administrator’s fees will be paid by us. There will be no brokerage charges or other charges to stockholders who participate in the plan except that, if a participant elects by written notice to the plan administrator to have the plan administrator sell part or all of the shares held by the plan administrator in the participant’s account and remit the proceeds to the participant, the plan administrator is authorized to deduct a $15.00 transaction fee plus a $0.10 per share brokerage commission from the proceeds. (3) Our base management fee is 1.75% of the average value of our total assets (other than cash and cash equivalents) but including assets purchased with borrowed amounts, and including assets owned by any consolidated entity. This item represents actual base management fees incurred by us during the year ended December 31, 2023 before the effect of the base management fee reduction on certain assets and assumes net assets of $162.0 million and leverage of $302.4 million, which reflects our net assets and leverage as of December 31, 2023. As discussed in footnote (8), below, OFS Advisor agreed to reduce a portion of its base management fee on certain assets; the base management fees of 5.21% presented in the table above does not reflect the (0.75)% effect of the base management fee reduction on certain assets. See “Management and Other Agreements—Investment Advisory Agreement.” (4) The incentive fee in the table above is based on actual amounts incurred for the Income Incentive Fee for the year ended December 31, 2023, which includes the effects of the base management fee reduction discussed in footnote (3). The Capital Gains Fee will be accrued, but not necessarily become payable, if, on a cumulative basis, the sum of net realized capital gains and losses plus net unrealized appreciation and depreciation is positive. The amount set forth in the table assumed the Capital Gains Fee is 0.0%. The two parts of the incentive fee follows: • The Income Incentive Fee, payable quarterly in arrears, equals 20.0% of our pre-incentive fee net investment income (including income that is accrued but not yet received in cash), subject to a 2.0% quarterly (8.0% annualized) hurdle rate and a “catch-up” provision measured as of the end of each calendar quarter. Under this provision, in any calendar quarter, OFS Advisor receives no incentive fee until our pre-incentive fee net investment income equals the hurdle rate of 2.0% but then receives, as a “catch-up,” 100% of our pre-incentive fee net investment income with respect to that portion of such pre-incentive fee net investment income, if any, that exceeds the hurdle rate but is less than 2.5%. The effect of this provision is that, if pre-incentive fee net investment income exceeds 2.5% in any calendar quarter, OFS Advisor will receive 20.0% of our pre-incentive fee net investment income as if a hurdle rate did not apply. There is no accumulation of amounts on the hurdle rate from quarter to quarter and accordingly there is no clawback of amounts previously paid if subsequent quarters are below the quarterly hurdle rate and there is no delay of payment if prior quarters are below the quarterly hurdle rate. • The Capital Gains Fee, payable annually in arrears, equals 20.0% of our realized capital gains on a cumulative basis, if any (or upon the termination of the Investment Advisory Agreement, as of the termination date), computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis, less the aggregate amount of any previously paid capital gain incentive fees. The incentive fee is determined on a consolidated basis. We accrue the Capital Gains Fee if, on a cumulative basis, the sum of net realized capital gains and losses plus net unrealized appreciation and depreciation is positive. See “Management and Other Agreements—Investment Advisory Agreement.” (5) Interest payments on borrowed funds is based on our estimated cost of funds on our outstanding indebtedness as of December 31, 2023. Based on our outstanding indebtedness as of December 31, 2023, our estimated annualized cost of funds, which includes all interest and amortization of debt issuance costs is 6.01%. As of December 31, 2023, our asset coverage ratio was 160% (which excludes the SBA debentures as a result of exemptive relief granted to us by the SEC) as permitted under Section 61(a)(2) of the 1940 Act. We may borrow additional funds from time to time to make investments to the extent we determine that the economic situation is conducive to doing so. As of December 31, 2023, availability under the Banc of California Credit Facility and BNP Facility was $25.0 million and $59.5 million, respectively, both subject to a borrowing base and other covenants. Our stockholders will bear directly or indirectly the costs of borrowings under any debt instruments we may enter into. (6) “Other Expenses” referenced in the table above are based on actual amounts incurred for the year ended December 31, 2023. “Other expenses” include our overhead expenses, including services under the Administration Agreement based on our allocable portion of overhead and other expenses incurred by OFS Services. See “Management and Other Agreements—Administration Agreement.” “Other Expenses” also include ongoing professional expenses to our independent accountants, legal counsel and compensation of independent directors. (7) Our stockholders indirectly bear the expenses of underlying funds or other investment vehicles that would be investment companies under section 3(a) of the 1940 Act but for the exceptions to that definition provided for in sections 3(c)(1) and 3(c)(7) of the 1940 Act (“Acquired Funds”) in which we invest. We do not currently invest in underlying funds or other investment companies and therefore do not expect to incur any acquired fund fees and expenses. The indirect expenses that are associated with our Structured Finance Securities are not included in the fee table presentation, but if such expenses were included in the fee table presentation then our total annual expenses would have been 22.91%. (8) OFS Advisor agreed to reduce a portion of its base management fee by reducing the portion of such fee from 1.75% to 1.00% on the average total assets (less cash) at the end of the two most recently completed quarters on assets held by the Company through OFSCC-FS, LLC, an indirect wholly owned subsidiary of the Company. The base management fee reduction is renewable on an annual basis and the amount of the base management fee reduction with respect to the OFSCC-FS Assets shall not be subject to recoupment by OFS Advisor. Example. The following example demonstrates the projected dollar amount of total cumulative expenses over various periods with respect to a hypothetical investment in our common stock. In calculating the following expense amounts, we have assumed we would have no additional leverage and that our annual operating expenses would remain at the levels set forth in the table above. The expense amounts assume an annual base management fee 1.75% for each year. Transaction expenses are not included in the following example. 1 Year 3 Years 5 Years 10 Years You would pay the following expenses on a $1,000 investment, assuming a 5.0% annual return $171 $437 $624 $888 While the example assumes, as required by the applicable rules of the SEC, a 5.0% annual return, our performance will vary and may result in a return greater or less than 5.0%. The incentive fee under the Investment Management Agreement, which, assuming a 5.0% annual return, would either not be payable or would have an insignificant impact on the expense amounts shown above, is not included in the above example. The above illustration assumes that we will not realize any capital gains (computed net of all realized capital losses and unrealized capital depreciation) in any of the indicated time periods. If we achieve sufficient returns on our investments, including through the realization of capital gains, to trigger an incentive fee of a material amount, our expenses and returns to our investors would be higher. For example, if we assumed that we received our 5.0% annual return completely in the form of net realized capital gains on our investments, computed net of all cumulative unrealized depreciation on our investments, the projected dollar amount of total cumulative expenses set forth in the above illustration would be as follows: 1 Year 3 Years 5 Years 10 Years You would pay the following expenses on a $1,000 investment, assuming a 5.0% annual return resulting entirely from net realized capital gains (all of which is subject to our incentive fee on capital gains) $180 $455 $644 $897 While the examples assume reinvestment of all distributions at NAV, participants in our DRIP will receive a number of shares of our common stock determined by dividing the total dollar amount of the distribution payable to a participant by the market price per share of our common stock at the close of trading on the dividend payment date. The market price per share of our common stock may be at, above or below NAV. The example should not be considered a representation of future expenses, and actual expenses may be greater or less than those shown.

This item represents actual base management fees incurred by us during the year ended December 31, 2023 before the effect of the base management fee reduction on certain assets and assumes net assets of $162.0 million and leverage of $302.4 million, which reflects our net assets and leverage as of December 31, 2023. As discussed in footnote (8), below, OFS Advisor agreed to reduce a portion of its base management fee on certain assets; the base management fees of 5.21% presented in the table above does not reflect the (0.75)% effect of the base management fee reduction on certain assets. See “Management and Other Agreements—Investment Advisory Agreement.” (4) The incentive fee in the table above is based on actual amounts incurred for the Income Incentive Fee for the year ended December 31, 2023, which includes the effects of the base management fee reduction discussed in footnote (3). The Capital Gains Fee will be accrued, but not necessarily become payable, if, on a cumulative basis, the sum of net realized capital gains and losses plus net unrealized appreciation and depreciation is positive. The amount set forth in the table assumed the Capital Gains Fee is 0.0%.

General Description of Registrant [Abstract]
Investment Objectives and Practices [Text Block]									Investment Criteria/Guidelines Our investment objective is to provide our stockholders with both current income and capital appreciation primarily through debt investments and, to a lesser extent, equity investments. We focus on investments in senior secured loans, including first lien, second lien, and unitranche loans, as well as subordinated loans and, to a lesser extent, common stock, preferred stock and Structured Finance Securities. In particular, we believe that structured equity with debt investments (i.e., typically senior secured unitranche loans, often with warrant coverage, and, at times, in companies with no financial sponsor) represent a strong relative value opportunity offering the borrower the convenience of dealing with one lender, which may result in a higher blended rate of interest to us than we might expect to receive under a traditional multi-tranche structure. We expect that our investments in the equity securities of portfolio companies, such as warrants, preferred stock, common stock and other equity interests, will principally be made in conjunction with our debt investments in those companies. Generally, we do not expect to make investments in companies or securities that OFS Advisor determines to be distressed investments (such as discounted debt instruments that have either experienced a default or have a significant potential for default), other than follow-on investments in portfolio companies of ours. We intend to continue to generate strong risk-adjusted net returns by assembling a diversified portfolio of investments across a broad range of industries. We target U.S. middle-market companies through OFS’s access to a network of financial institutions, private equity sponsors, investment banks, consultants and attorneys, and our proprietary database of borrowers developed over OFS’s 25 year history of lending to middle-market companies. A typical targeted borrower will exhibit certain of the following characteristics: • number of employees between 150 and 2,000; • revenues between $15 million and $300 million; • annual EBITDA between $5 million and $50 million; • private companies owned by private equity firms or owners/operators; • enterprise value between $10 million and $500 million; • effective and experienced management teams; • defensible market share; • solid historical financial performance, including a steady stream of cash flow; • high degree of recurring revenue; • diversity of customers, markets, products and geography; and • differentiated products or services.
Risk Factors [Table Text Block]									RISK FACTORS Investing in our securities involves a number of significant risks. In addition to the other information contained in this Annual Report on Form 10-K, you should consider carefully the following information before making an investment in our securities. The risks set out below are not the only risks we face. Additional risks and uncertainties not presently known to us or not presently deemed material by us might also impair our operations and performance. If any of the following events occur, our business, financial condition and results of operations could be materially and adversely affected. In such case, our NAV and the trading price of our securities could decline, and you may lose all or part of your investment. The risk factors described below are the principal risk factors associated with an investment in our securities as well as those factors generally associated with an investment company with investment objectives, investment policies, capital structure or trading markets similar to ours. Summary Risk Factors We are subject to risks related to our business and structure. • Global economic, political and market conditions may adversely affect our business, our ability to access capital, and our results of operations and financial condition, including our revenue growth and profitability. • Due to economic disruptions, we may not be able to increase our dividends and may reduce or defer our dividends and choose to incur U.S. federal excise tax in order to preserve cash and maintain flexibility. • We are dependent upon the OFSC senior professionals for our future success and upon their access to the investment professionals and partners of OFSC and its affiliates. • A significant amount of our portfolio investments are recorded at fair value and OFS Advisor, our “valuation designee,” determines the fair value of our investments in good faith pursuant to Rule 2a-5 under the 1940 Act. As a result, there will be uncertainty as to the value of our portfolio investments and the participation of OFS Advisor’s professionals in our valuation process could result in a conflict of interest. • We may finance our investments with borrowed money, which magnifies the potential for gain or loss on amounts invested and may increase the risk of investing in us. • Insufficient cash flows may increase our risk of default of our debt obligations, including under our Unsecured Notes and our BNP Facility. • We will be subject to U.S. federal income tax at corporate rates if we are unable to maintain our tax treatment as a RIC. • In the future, we may choose to pay distributions in our own stock and stockholders may be required to pay tax in excess of the cash they receive. • Because we expect to distribute substantially all of our net ordinary income and net realized capital gains to our stockholders, we may need additional capital to finance our growth and such capital may not be available on favorable terms or at all. • Changes in the laws or regulations governing our business, or changes in the interpretations thereof, and any failure by us to comply with these laws or regulations, could have a material adverse effect on our, and our portfolio companies’ business, results of operations or financial condition. • Our Board may change our investment objectives, operating policies and strategies without prior notice or stockholder approval. We are subject to risks related to OFS Advisor and its Affiliates. • We have potential conflicts of interest related to obligations that OFS Advisor or its affiliates may have to other clients. • We have potential conflicts of interest related to the purchases and sales that OFS Advisor makes on our behalf and/or on behalf of Affiliated Accounts. • The valuation process for certain of our portfolio holdings may create a conflict of interest. • Our ability to enter into transactions with our affiliates is restricted, which may limit the scope of investments available to us. • Our incentive fee structure may create incentives for OFS Advisor that are not fully aligned with the interests of our stockholders. • OFS Advisor’s liability is limited under the Investment Advisory Agreement, and we have agreed to indemnify OFS Advisor against certain liabilities, which may lead OFS Advisor to act in a riskier manner on our behalf than it would when acting for its own account. • OFS Advisor can resign on 60 days’ notice, and we may not be able to find a suitable replacement within that time, resulting in a disruption in our operations that could adversely affect our financial condition, business and results of operations. We are subject to risks related to our investments. • Inflation may adversely affect the business, results of operations and financial condition of our portfolio companies. • Any of our portfolio companies operating in the Health Care and Social Assistance industry are subject to extensive government regulation and certain other risks particular to that industry. • Our investments in private and middle-market portfolio companies are generally considered lower credit quality obligations, are risky, and we could lose all or part of our investment. • Our investments in Structured Finance Securities carry additional risks to the risks associated with investing in private debt. • Our investments in Structured Finance Securities are more likely to suffer a loss of all or a portion of their value in the event of a default. • We are a non-diversified management investment company within the meaning of the 1940 Act, and therefore we are not limited by the 1940 Act with respect to the proportion of our assets that may be invested in securities of a single issuer. • If we make subordinated debt investments, the obligors or the portfolio companies may not generate sufficient cash flow to service their debt obligations to us. • We and our investments are subject to interest rate risk. We are subject to risks related to our securities and an investment in our common stock. • There is a risk that stockholders may not receive distributions or that our distributions may not grow over time and a portion of our distributions may be a return of capital. • The market price of our common stock may fluctuate and decrease significantly. • Sales of substantial amounts of our common stock in the public market may have an adverse effect on the market price of our common stock. • Our common stock may trade below its NAV per share, which limits our ability to raise additional equity capital. Risks Related to Our Business and Structure Global economic, political and market conditions may adversely affect our business, our ability to access capital, and our results of operations and financial condition, including our revenue growth and profitability. The state of current worldwide financial markets, as well as various social, economic and political tensions in the United States and around the world (including war, terrorist attacks and other forms of conflict), may contribute to increased market volatility, may have long term effects on the United States and worldwide financial markets, and may cause economic uncertainties or deterioration in the United States and worldwide. For example, global financial markets are currently experiencing supply chain disruptions, significant labor and resource shortages, elevated interest rates and the effects of high inflation. In addition, there is currently geopolitical, economic and financial market instability in the United States, the United Kingdom, the European Union and China. The ongoing war between Russia and Ukraine and the resulting global responses, including economic sanctions by the United States, the European Union and other countries, and the escalated armed conflict in the Middle East have increased and could continue to increase volatility and uncertainty in the financial markets and adversely affect regional and global economies. The extent and duration of the ongoing conflicts in Ukraine and the Middle East and the repercussions of such conflicts are impossible to predict, but could result in significant market disruptions and may further negatively affect global supply chains, energy prices, inflation and global growth. The elevated inflationary environment may continue and some economists predict that the U.S. economy may enter an economic recession. Any disruptions in the capital markets, as a result of economic, political and market instability (including as a result of a shutdown of U.S. government services, strikes, work stoppages, labor shortages, labor disputes, supply chain disruptions and accidents), may increase the spread between the yields realized on risk-free and higher risk securities and can result in illiquidity in parts of the capital markets, significant write-offs in the financial sector and re-pricing of credit risk in the broadly syndicated market. These and any other unfavorable economic conditions could increase our funding costs, limit our access to the capital markets and result in a decision by lenders not to extend credit to us. The global pandemic caused by the outbreak of the novel strain of coronavirus ("COVID-19") has in the past led, and may continue to lead, to significant economic disruption in the economy of the United States and the economies of other nations. While many of the emergency measures and recommendations imposed by governmental authorities in response to the pandemic, including restrictions on travel and the closure of non-essential businesses have been eased, the pandemic and the resulting economic dislocations caused substantial disruption, volatility and a reduction in liquidity in the capital markets and the credit markets, including the leveraged loan market specifically, which may continue for an extended period. Any such volatility or additional waves of the COVID-19 outbreak or future pandemics, as well as the generally negative economic impact of such events, may have adverse impacts on our business and our results of operations and financial condition. While certain markets have shown signs of stabilizing, market conditions remain uncertain and a period of deterioration and volatility could re-emerge. Negative economic trends would also increase the likelihood that major financial institutions or other entities having a significant impact on the financial and credit markets may suffer a bankruptcy or insolvency, as occurred during the recession in the U.S. economy in 2008. In addition, certain industries may feel the impact of such negative economic trends more than others. There is a material possibility that economic activity will be volatile or will slow significantly, and some obligors may be significantly and negatively impacted by these negative economic trends. Although the leveraged finance and CLO markets have made significant recoveries from the adverse impact of the credit crisis, there can be no assurance that the leveraged finance and CLO markets will not be adversely impacted by future economic downturns or market volatility. The financial results of middle-market companies in which we primarily invest, have experienced deterioration because of market volatility, which could ultimately lead to difficulty in meeting debt service requirements and an increase in defaults, and further deterioration will further depress the outlook for middle-market companies. Further, adverse economic conditions have decreased, and may in the future decrease, the value of collateral securing some of our loans and the value of our equity investments. Such conditions have required, and may in the future require, us to modify the payment terms of our investments, including changes in PIK interest provisions and/or cash interest rates. The performance of certain of our portfolio companies has been, and in the future may be, negatively impacted by these economic or other conditions, which can result in our receipt of reduced interest income from our portfolio companies and/or realized and unrealized losses related to our investments, and, in turn, may adversely affect distributable income and have a material adverse effect on our results of operations. Significant disruption or volatility in the capital markets may also have a negative effect on the valuations of our investments. While most of our investments are not publicly traded, applicable accounting standards require us to assume as part of our valuation process that our investments are sold in a principal market to market participants (even if we plan on holding an investment through its maturity). Significant disruption or volatility in the capital markets may also affect the pace of our investment activity and the potential for liquidity events involving our investments. Thus, the illiquidity of our investments may make it difficult for us to sell such investments to access capital if required, and as a result, we could realize significantly less than the value at which we have recorded our investments if we were required to sell them for liquidity purposes. An inability to raise or access capital could have a material adverse effect on our business, financial condition or results of operations. We may also be subject to risk arising from a default by one of several large institutions that are dependent on one another to meet their liquidity or operational needs, so that a default by one institution may cause a series of defaults by the other institutions. This is sometimes referred to as “systemic risk” and may adversely affect financial intermediaries with which we interact in the conduct of our business. Overall uncertainty in the economic environment globally and in the United States may adversely affect our business, ability to secure debt financing, results of operations and financial condition, including our revenue growth and profitability. We continuously monitor developments and seek to manage our investments in a manner consistent with achieving our investment objective, but there can be no assurance that we will be successful in doing so. Due to economic disruptions, we may not be able to increase our dividends and may reduce or defer our dividends and choose to incur U.S. federal excise tax in order to preserve cash and maintain flexibility. As a BDC, we are not required to make any distributions to stockholders other than in connection with our election to be taxed as a RIC under subchapter M of the Code. In order to maintain our tax treatment as a RIC, we must distribute to stockholders for each taxable year at least 90% of our ICTI. If we qualify for taxation as a RIC, we generally will not be subject to corporate-level U.S. federal income tax on our ICTI and net capital gains (i.e., realized net long-term capital gains in excess of realized net short-term capital losses) that we timely distribute to stockholders. We will be subject to a 4% U.S. federal excise tax on undistributed earnings of a RIC unless we distribute each calendar year at least the sum of (i) 98.0% of our ordinary income for the calendar year, (ii) 98.2% of our capital gains in excess of capital losses for the one-year period ending on October 31 of the calendar year, and (iii) any ordinary income and net capital gains for preceding years that were not distributed during such years and on which we paid no U.S. federal income tax. Under the Code, we may satisfy certain of our RIC distributions with dividends paid after the end of the current year. In particular, if we pay a distribution in January of the following year that was declared in October, November, or December of the current year and is payable to stockholders of record in the current year, the dividend will be treated for all U.S. federal tax purposes as if it were paid on December 31 of the current year. In addition, under the Code, we may pay dividends, referred to as “spillover dividends,” that we (i) declare on or before the later of the 15th day of the 9th month following the close of our taxable year or in the case of an extension of time for filing our return for the taxable year, the due date for filing such return taking into account such extension and (ii) pay during the following taxable year (but not later than the date of the first dividend payment of the same type of dividend made after such declaration). Such dividends will allow us to maintain our qualification for taxation as a RIC and eliminate our liability for corporate-level U.S. federal income tax. Under these spillover dividend procedures, we may defer distribution of income earned during the current year until December of the following year. For example, we may defer distributions of income earned during 2023 until as late as December 31, 2024. However, if we choose to pay a spillover dividend, we will still incur the 4% U.S. federal excise tax on some or all of the distribution. Due to disruptions in the economy, including elevated interest rates and high inflation rates, we may take certain actions with respect to the timing and amounts of our distributions in order to preserve cash and maintain flexibility. For example, we may not be able to increase our dividends. In addition, we may reduce our dividends and/or defer our dividends to the following taxable year. If we defer our dividends, we may choose to utilize the spillover dividend rules discussed above and incur the 4% U.S. federal excise tax on such amounts. To further preserve cash, we may combine these reductions or deferrals of dividends with one or more distributions that are payable partially in our stock. See “ Item 1A. Risk Factors—Risks Related to our Business and Structure—In the future, we may choose to pay distributions in our own stock and stockholders may be required to pay tax in excess of the cash they receive. ” We are dependent upon the OFSC senior professionals for our future success and upon their access to the investment professionals and partners of OFSC and its affiliates. We do not have any internal management capacity or employees. We will depend on the diligence, skill and network of business contacts of the OFSC senior professionals to achieve our investment objective. Our future success will depend, to a significant extent, on the continued service and coordination of the OFSC senior management team, particularly Bilal Rashid, Senior Managing Director and President of OFSC, and Jeffrey A. Cerny, Senior Managing Director of OFSC. Each of these individuals is an employee at will of OFSC. In addition, we rely on the services of Richard Ressler, Chairman of the executive committee of OFSAM Holdings and Chairman of certain of the Advisor Investment Committees, pursuant to a consulting agreement with Orchard Capital Corporation. The departure of Mr. Ressler or any of the senior managers of OFSC, or of a significant number of its other investment professionals, could have a material adverse effect on our ability to achieve our investment objective. We expect that OFS Advisor will continue to evaluate, negotiate, structure, close and monitor our investments in accordance with the terms of the Investment Advisory Agreement. We can offer no assurance, however, that OFSC senior professionals will continue to provide investment advice to us. If these individuals do not maintain their existing relationships with OFSC and its affiliates and do not develop new relationships with other sources of investment opportunities, we may not be able to grow our investment portfolio or achieve our investment objective. In addition, individuals with whom the OFSC senior professionals have relationships are not obligated to provide us with investment opportunities. Therefore, we can offer no assurance that such relationships will generate investment opportunities for us. OFS Advisor is a wholly owned subsidiary of OFSAM, has no employees and depends upon access to the investment professionals and other resources of OFSC and its affiliates to fulfill its obligations to us under the Investment Advisory Agreement. OFS Advisor also depends upon OFSC to obtain access to deal flow generated by the professionals of OFSC and its affiliates. Under a Staffing Agreement between OFSC, a wholly owned subsidiary of OFSAM, and OFS Advisor, OFSC has agreed to provide OFS Advisor with the resources necessary to fulfill these obligations. The Staffing Agreement provides that OFSC will make available to OFS Advisor experienced investment professionals and access to the senior investment personnel of OFSC for purposes of evaluating, negotiating, structuring, closing and monitoring our investments. We are not a party to this Staffing Agreement and cannot assure stockholders that OFSC will fulfill its obligations under the agreement. If OFSC fails to perform, we cannot assure stockholders that OFS Advisor will enforce the Staffing Agreement or that such agreement will not be terminated by either party or that we will continue to have access to the investment professionals of OFSC and its affiliates or their information and deal flow. The investment committees that oversee our investment activities are provided by OFS Advisor under the Investment Advisory Agreement. The loss of any member of the Advisor Investment Committees or of other OFSC senior professionals could limit our ability to achieve our investment objective and operate as we anticipate. This could have a material adverse effect on our financial condition and results of operation. Our business model depends to a significant extent upon strong referral relationships with financial institutions, sponsors and investment professionals. Any inability of OFS Advisor to maintain or develop these relationships, or the failure of these relationships to generate investment opportunities, could adversely affect our business. We depend upon OFS Advisor to maintain relationships with financial institutions, sponsors and investment professionals, and we will continue to rely to a significant extent upon these relationships to provide us with potential investment opportunities. If OFS Advisor fails to maintain such relationships, or to develop new relationships with other sources of investment opportunities, we will not be able to grow our investment portfolio. In addition, individuals with whom the principals of OFS Advisor have relationships are not obligated to provide us with investment opportunities, and, therefore, we can offer no assurance that these relationships will generate investment opportunities for us in the future. Our financial condition and results of operation will depend on our ability to manage our business effectively. Our ability to achieve our investment objective and grow will depend on our ability to manage our business. This will depend, in turn, on the ability of the Advisor Investment Committees to identify, invest in and monitor companies that meet our investment criteria. The achievement of our investment objectives on a cost-effective basis will depend upon the Advisor Investment Committees’ ability to execute our investment process, their ability to provide competent, attentive and efficient services to us and, to a lesser extent, our access to financing on acceptable terms. OFS Advisor has substantial responsibilities under the Investment Advisory Agreement. OFS Advisor’s senior professionals and other personnel of OFS Advisor’s affiliates, including OFSC, may be called upon to provide managerial assistance to our portfolio companies. These activities may distract them or slow our rate of investment. Any failure to manage our business and our future growth effectively could have a material adverse effect on our business, financial condition and results of operations. To the extent PIK interest and PIK dividends constitute a portion of our income, we will be required to include such income in taxable and accounting income prior to receipt of cash representing such income. Our investments may include contractual PIK interest or PIK dividends, which represents contractual interest or dividends added to a loan balance or equity security and due at the end of such loan’s or equity security’s term. To the extent PIK interest and PIK dividends constitute a portion of our income, we will be exposed to typical risks associated with such income being required to be included in taxable and accounting income prior to receipt of cash. Such risks include: • The higher interest or dividend rates of PIK instruments reflect the payment deferral and increased risk associated with these instruments, and PIK instruments often represent a significantly higher risk than non-PIK instruments. • Even if the accounting conditions for income accrual are met, the borrower could still default when our actual collection is supposed to occur at the maturity of the obligation. • PIK instruments may have unreliable valuations because their continuing accruals require continuing judgments about the collectability of the deferred payments and the value of any associated collateral. PIK income may also create uncertainty about the source of our cash distributions. • For accounting purposes, any cash distributions to stockholders representing PIK income are not treated as coming from paid-in capital. As a result, despite the fact that a distribution representing PIK income could be paid out of amounts invested by our stockholders, the 1940 Act does not require that stockholders be given notice of this fact by reporting it as a return of capital. • PIK interest or dividends have the effect of generating investment income at a compounding rate, thereby further increasing the incentive fees payable to OFS Advisor. Similarly, all things being equal, the deferral associated with PIK interest or dividends also decreases the investment principal-to-value ratio at a compounding rate. A significant amount of our portfolio investments are recorded at fair value and OFS Advisor, our “valuation designee,” determines the fair value of our investments in good faith pursuant to Rule 2a-5 under the 1940 Act. As a result, there will be uncertainty as to the value of our portfolio investments and the participation of OFS Advisor’s professionals in our valuation process could result in a conflict of interest. Many of our portfolio investments take the form of securities that are not publicly traded and their fair value may not be readily determinable. In December 2020, the SEC adopted Rule 2a-5 under the 1940 Act (“Rule 2a-5”), which establishes requirements for good faith determinations of fair value, and addresses both the Board’s and the “valuation designee’s” roles and responsibilities relating to fair valuation. On September 7, 2022, pursuant to Rule 2a-5, our Board designated OFS Advisor, as valuation designee, to perform fair value determinations relating to our investments, for which market quotations are not readily available. In order for the Board to maintain oversight, OFS Advisor implemented the requirements as prescribed in Rule 2a-5. The determination of fair value and, consequently, the amount of unrealized gains and losses in our portfolio, are, to a significant degree, subjective and dependent on a valuation process undertaken by OFS Advisor and overseen by our Board. Valuation of certain investments will also be based, in part, upon third party valuation models which take into account various unobservable inputs. A majority of our investments are classified as Level 3 under ASC Topic 820. This means that our portfolio valuations are based on unobservable inputs and assumptions about how market participants would price the asset or liability in question. Inputs into the determination of fair value of our portfolio investments require significant management judgment and estimation. Even if observable market data is available, such information may be the result of consensus pricing information or broker quotes, which include a disclaimer that the broker would not be held to such a price in an actual transaction. The non-binding nature of consensus pricing and/or quotes accompanied by disclaimers materially reduces the reliability of such information. We presently retain the services of independent service providers to prepare the valuation of the majority of these securities. Certain factors that may be considered in determining the fair value of our investments include third-party yield benchmarks and comparison to publicly traded securities including such factors as yield, maturity and measures of credit quality, the enterprise value of a portfolio company, the nature and realizable value of any collateral, the portfolio company’s ability to make payments and its earnings and cash flow, the markets in which the portfolio company does business and other relevant factors. The models, information and/or underlying assumptions utilized by OFS Advisor will not always allow OFS Advisor to correctly capture the fair value of an asset. Because such valuations, and particularly valuations of securities that are not publicly traded, like those we hold, are inherently uncertain, they may fluctuate materially over short periods of time and may be based on estimates. OFS Advisor’s determinations of fair value may differ materially from the values that would have been used if an active public market for these securities existed. OFS Advisor’s determinations of the fair value of our investments have a material impact on our net earnings through the recording of unrealized appreciation or depreciation of investments and may cause our NAV on a given date to understate or overstate, possibly materially, the value that we may ultimately realize on one or more of our investments. The participation of OFS Advisor’s professionals in our valuation process could also result in a conflict of interest since OFS Advisor’s base management fee is based, in part, on the average value of our total assets (other than cash and cash equivalents but including assets purchased with borrowed amounts and including assets owned by any consolidated entity). We may finance our investments with borrowed money, which magnifies the potential for gain or loss on amounts invested and may increase the risk of investing in us. The use of leverage magnifies the potential for gain or loss on amounts invested. The use of leverage is generally considered a speculative investment technique and increases the risks associated with investing in our securities. We may pledge up to 100% of our assets and may grant a security interest in all of our assets, other than assets held in OFSCC-FS and SBIC I LP, under the terms of any debt instruments we may enter into with lenders. In addition, under the terms of any credit facility or other debt instrument we enter into, we are likely to be required by its terms to use the net proceeds of any investments that we sell to repay a portion of the amount borrowed under such facility or instrument before applying such net proceeds to any other uses. If the value of our assets decreases, leveraging would cause NAV to decline more sharply than it otherwise would have had we not leveraged, thereby magnifying losses or eliminating our equity stake in a leveraged investment. Similarly, any decrease in our revenue or income will cause our net income to decline more sharply than it would have had we not borrowed. Such a decline would also negatively affect our ability to make dividend payments on our common stock or preferred stock. Our ability to service our debt will depend largely on our financial performance and will be subject to prevailing economic conditions and competitive pressures. Moreover, because the base management fee payable to OFS Advisor is payable based on our total assets (other than cash and cash equivalents but including assets purchased with borrowed amounts and including assets owned by any consolidated entity), OFS Advisor has a financial incentive to cause us to incur leverage which may not be consistent with our stockholders’ interests. In addition, our common stockholders will bear the burden of any increase in our expenses as a result of our use of leverage, including interest expenses and any increase in the base management fee payable to OFS Advisor. On May 3, 2018, the Board, including a “required majority” (as such term is defined in Section 57(o) of the 1940 Act) of the Board, approved the application of a reduced 150% asset coverage ratio to us; therefore, provided certain conditions are met, we became subject to the reduced asset coverage ratio as of May 3, 2019. See “ Item 1A. Risk Factors—Risks Related to our Business and Structure—Because we received the approval of our Board, we became subject to 150% asset coverage effective May 3, 2019. ” As o

Risk [Text Block]									Summary Risk Factors We are subject to risks related to our business and structure. • Global economic, political and market conditions may adversely affect our business, our ability to access capital, and our results of operations and financial condition, including our revenue growth and profitability. • Due to economic disruptions, we may not be able to increase our dividends and may reduce or defer our dividends and choose to incur U.S. federal excise tax in order to preserve cash and maintain flexibility. • We are dependent upon the OFSC senior professionals for our future success and upon their access to the investment professionals and partners of OFSC and its affiliates. • A significant amount of our portfolio investments are recorded at fair value and OFS Advisor, our “valuation designee,” determines the fair value of our investments in good faith pursuant to Rule 2a-5 under the 1940 Act. As a result, there will be uncertainty as to the value of our portfolio investments and the participation of OFS Advisor’s professionals in our valuation process could result in a conflict of interest. • We may finance our investments with borrowed money, which magnifies the potential for gain or loss on amounts invested and may increase the risk of investing in us. • Insufficient cash flows may increase our risk of default of our debt obligations, including under our Unsecured Notes and our BNP Facility. • We will be subject to U.S. federal income tax at corporate rates if we are unable to maintain our tax treatment as a RIC. • In the future, we may choose to pay distributions in our own stock and stockholders may be required to pay tax in excess of the cash they receive. • Because we expect to distribute substantially all of our net ordinary income and net realized capital gains to our stockholders, we may need additional capital to finance our growth and such capital may not be available on favorable terms or at all. • Changes in the laws or regulations governing our business, or changes in the interpretations thereof, and any failure by us to comply with these laws or regulations, could have a material adverse effect on our, and our portfolio companies’ business, results of operations or financial condition. • Our Board may change our investment objectives, operating policies and strategies without prior notice or stockholder approval. We are subject to risks related to OFS Advisor and its Affiliates. • We have potential conflicts of interest related to obligations that OFS Advisor or its affiliates may have to other clients. • We have potential conflicts of interest related to the purchases and sales that OFS Advisor makes on our behalf and/or on behalf of Affiliated Accounts. • The valuation process for certain of our portfolio holdings may create a conflict of interest. • Our ability to enter into transactions with our affiliates is restricted, which may limit the scope of investments available to us. • Our incentive fee structure may create incentives for OFS Advisor that are not fully aligned with the interests of our stockholders. • OFS Advisor’s liability is limited under the Investment Advisory Agreement, and we have agreed to indemnify OFS Advisor against certain liabilities, which may lead OFS Advisor to act in a riskier manner on our behalf than it would when acting for its own account. • OFS Advisor can resign on 60 days’ notice, and we may not be able to find a suitable replacement within that time, resulting in a disruption in our operations that could adversely affect our financial condition, business and results of operations. We are subject to risks related to our investments. • Inflation may adversely affect the business, results of operations and financial condition of our portfolio companies. • Any of our portfolio companies operating in the Health Care and Social Assistance industry are subject to extensive government regulation and certain other risks particular to that industry. • Our investments in private and middle-market portfolio companies are generally considered lower credit quality obligations, are risky, and we could lose all or part of our investment. • Our investments in Structured Finance Securities carry additional risks to the risks associated with investing in private debt. • Our investments in Structured Finance Securities are more likely to suffer a loss of all or a portion of their value in the event of a default. • We are a non-diversified management investment company within the meaning of the 1940 Act, and therefore we are not limited by the 1940 Act with respect to the proportion of our assets that may be invested in securities of a single issuer. • If we make subordinated debt investments, the obligors or the portfolio companies may not generate sufficient cash flow to service their debt obligations to us. • We and our investments are subject to interest rate risk. We are subject to risks related to our securities and an investment in our common stock. • There is a risk that stockholders may not receive distributions or that our distributions may not grow over time and a portion of our distributions may be a return of capital. • The market price of our common stock may fluctuate and decrease significantly. • Sales of substantial amounts of our common stock in the public market may have an adverse effect on the market price of our common stock. • Our common stock may trade below its NAV per share, which limits our ability to raise additional equity capital.
Risk Related To Business And Structure [Member]
General Description of Registrant [Abstract]
Risk [Text Block]									Risks Related to Our Business and Structure Global economic, political and market conditions may adversely affect our business, our ability to access capital, and our results of operations and financial condition, including our revenue growth and profitability. The state of current worldwide financial markets, as well as various social, economic and political tensions in the United States and around the world (including war, terrorist attacks and other forms of conflict), may contribute to increased market volatility, may have long term effects on the United States and worldwide financial markets, and may cause economic uncertainties or deterioration in the United States and worldwide. For example, global financial markets are currently experiencing supply chain disruptions, significant labor and resource shortages, elevated interest rates and the effects of high inflation. In addition, there is currently geopolitical, economic and financial market instability in the United States, the United Kingdom, the European Union and China. The ongoing war between Russia and Ukraine and the resulting global responses, including economic sanctions by the United States, the European Union and other countries, and the escalated armed conflict in the Middle East have increased and could continue to increase volatility and uncertainty in the financial markets and adversely affect regional and global economies. The extent and duration of the ongoing conflicts in Ukraine and the Middle East and the repercussions of such conflicts are impossible to predict, but could result in significant market disruptions and may further negatively affect global supply chains, energy prices, inflation and global growth. The elevated inflationary environment may continue and some economists predict that the U.S. economy may enter an economic recession. Any disruptions in the capital markets, as a result of economic, political and market instability (including as a result of a shutdown of U.S. government services, strikes, work stoppages, labor shortages, labor disputes, supply chain disruptions and accidents), may increase the spread between the yields realized on risk-free and higher risk securities and can result in illiquidity in parts of the capital markets, significant write-offs in the financial sector and re-pricing of credit risk in the broadly syndicated market. These and any other unfavorable economic conditions could increase our funding costs, limit our access to the capital markets and result in a decision by lenders not to extend credit to us. The global pandemic caused by the outbreak of the novel strain of coronavirus ("COVID-19") has in the past led, and may continue to lead, to significant economic disruption in the economy of the United States and the economies of other nations. While many of the emergency measures and recommendations imposed by governmental authorities in response to the pandemic, including restrictions on travel and the closure of non-essential businesses have been eased, the pandemic and the resulting economic dislocations caused substantial disruption, volatility and a reduction in liquidity in the capital markets and the credit markets, including the leveraged loan market specifically, which may continue for an extended period. Any such volatility or additional waves of the COVID-19 outbreak or future pandemics, as well as the generally negative economic impact of such events, may have adverse impacts on our business and our results of operations and financial condition. While certain markets have shown signs of stabilizing, market conditions remain uncertain and a period of deterioration and volatility could re-emerge. Negative economic trends would also increase the likelihood that major financial institutions or other entities having a significant impact on the financial and credit markets may suffer a bankruptcy or insolvency, as occurred during the recession in the U.S. economy in 2008. In addition, certain industries may feel the impact of such negative economic trends more than others. There is a material possibility that economic activity will be volatile or will slow significantly, and some obligors may be significantly and negatively impacted by these negative economic trends. Although the leveraged finance and CLO markets have made significant recoveries from the adverse impact of the credit crisis, there can be no assurance that the leveraged finance and CLO markets will not be adversely impacted by future economic downturns or market volatility. The financial results of middle-market companies in which we primarily invest, have experienced deterioration because of market volatility, which could ultimately lead to difficulty in meeting debt service requirements and an increase in defaults, and further deterioration will further depress the outlook for middle-market companies. Further, adverse economic conditions have decreased, and may in the future decrease, the value of collateral securing some of our loans and the value of our equity investments. Such conditions have required, and may in the future require, us to modify the payment terms of our investments, including changes in PIK interest provisions and/or cash interest rates. The performance of certain of our portfolio companies has been, and in the future may be, negatively impacted by these economic or other conditions, which can result in our receipt of reduced interest income from our portfolio companies and/or realized and unrealized losses related to our investments, and, in turn, may adversely affect distributable income and have a material adverse effect on our results of operations. Significant disruption or volatility in the capital markets may also have a negative effect on the valuations of our investments. While most of our investments are not publicly traded, applicable accounting standards require us to assume as part of our valuation process that our investments are sold in a principal market to market participants (even if we plan on holding an investment through its maturity). Significant disruption or volatility in the capital markets may also affect the pace of our investment activity and the potential for liquidity events involving our investments. Thus, the illiquidity of our investments may make it difficult for us to sell such investments to access capital if required, and as a result, we could realize significantly less than the value at which we have recorded our investments if we were required to sell them for liquidity purposes. An inability to raise or access capital could have a material adverse effect on our business, financial condition or results of operations. We may also be subject to risk arising from a default by one of several large institutions that are dependent on one another to meet their liquidity or operational needs, so that a default by one institution may cause a series of defaults by the other institutions. This is sometimes referred to as “systemic risk” and may adversely affect financial intermediaries with which we interact in the conduct of our business. Overall uncertainty in the economic environment globally and in the United States may adversely affect our business, ability to secure debt financing, results of operations and financial condition, including our revenue growth and profitability. We continuously monitor developments and seek to manage our investments in a manner consistent with achieving our investment objective, but there can be no assurance that we will be successful in doing so. Due to economic disruptions, we may not be able to increase our dividends and may reduce or defer our dividends and choose to incur U.S. federal excise tax in order to preserve cash and maintain flexibility. As a BDC, we are not required to make any distributions to stockholders other than in connection with our election to be taxed as a RIC under subchapter M of the Code. In order to maintain our tax treatment as a RIC, we must distribute to stockholders for each taxable year at least 90% of our ICTI. If we qualify for taxation as a RIC, we generally will not be subject to corporate-level U.S. federal income tax on our ICTI and net capital gains (i.e., realized net long-term capital gains in excess of realized net short-term capital losses) that we timely distribute to stockholders. We will be subject to a 4% U.S. federal excise tax on undistributed earnings of a RIC unless we distribute each calendar year at least the sum of (i) 98.0% of our ordinary income for the calendar year, (ii) 98.2% of our capital gains in excess of capital losses for the one-year period ending on October 31 of the calendar year, and (iii) any ordinary income and net capital gains for preceding years that were not distributed during such years and on which we paid no U.S. federal income tax. Under the Code, we may satisfy certain of our RIC distributions with dividends paid after the end of the current year. In particular, if we pay a distribution in January of the following year that was declared in October, November, or December of the current year and is payable to stockholders of record in the current year, the dividend will be treated for all U.S. federal tax purposes as if it were paid on December 31 of the current year. In addition, under the Code, we may pay dividends, referred to as “spillover dividends,” that we (i) declare on or before the later of the 15th day of the 9th month following the close of our taxable year or in the case of an extension of time for filing our return for the taxable year, the due date for filing such return taking into account such extension and (ii) pay during the following taxable year (but not later than the date of the first dividend payment of the same type of dividend made after such declaration). Such dividends will allow us to maintain our qualification for taxation as a RIC and eliminate our liability for corporate-level U.S. federal income tax. Under these spillover dividend procedures, we may defer distribution of income earned during the current year until December of the following year. For example, we may defer distributions of income earned during 2023 until as late as December 31, 2024. However, if we choose to pay a spillover dividend, we will still incur the 4% U.S. federal excise tax on some or all of the distribution. Due to disruptions in the economy, including elevated interest rates and high inflation rates, we may take certain actions with respect to the timing and amounts of our distributions in order to preserve cash and maintain flexibility. For example, we may not be able to increase our dividends. In addition, we may reduce our dividends and/or defer our dividends to the following taxable year. If we defer our dividends, we may choose to utilize the spillover dividend rules discussed above and incur the 4% U.S. federal excise tax on such amounts. To further preserve cash, we may combine these reductions or deferrals of dividends with one or more distributions that are payable partially in our stock. See “ Item 1A. Risk Factors—Risks Related to our Business and Structure—In the future, we may choose to pay distributions in our own stock and stockholders may be required to pay tax in excess of the cash they receive. ” We are dependent upon the OFSC senior professionals for our future success and upon their access to the investment professionals and partners of OFSC and its affiliates. We do not have any internal management capacity or employees. We will depend on the diligence, skill and network of business contacts of the OFSC senior professionals to achieve our investment objective. Our future success will depend, to a significant extent, on the continued service and coordination of the OFSC senior management team, particularly Bilal Rashid, Senior Managing Director and President of OFSC, and Jeffrey A. Cerny, Senior Managing Director of OFSC. Each of these individuals is an employee at will of OFSC. In addition, we rely on the services of Richard Ressler, Chairman of the executive committee of OFSAM Holdings and Chairman of certain of the Advisor Investment Committees, pursuant to a consulting agreement with Orchard Capital Corporation. The departure of Mr. Ressler or any of the senior managers of OFSC, or of a significant number of its other investment professionals, could have a material adverse effect on our ability to achieve our investment objective. We expect that OFS Advisor will continue to evaluate, negotiate, structure, close and monitor our investments in accordance with the terms of the Investment Advisory Agreement. We can offer no assurance, however, that OFSC senior professionals will continue to provide investment advice to us. If these individuals do not maintain their existing relationships with OFSC and its affiliates and do not develop new relationships with other sources of investment opportunities, we may not be able to grow our investment portfolio or achieve our investment objective. In addition, individuals with whom the OFSC senior professionals have relationships are not obligated to provide us with investment opportunities. Therefore, we can offer no assurance that such relationships will generate investment opportunities for us. OFS Advisor is a wholly owned subsidiary of OFSAM, has no employees and depends upon access to the investment professionals and other resources of OFSC and its affiliates to fulfill its obligations to us under the Investment Advisory Agreement. OFS Advisor also depends upon OFSC to obtain access to deal flow generated by the professionals of OFSC and its affiliates. Under a Staffing Agreement between OFSC, a wholly owned subsidiary of OFSAM, and OFS Advisor, OFSC has agreed to provide OFS Advisor with the resources necessary to fulfill these obligations. The Staffing Agreement provides that OFSC will make available to OFS Advisor experienced investment professionals and access to the senior investment personnel of OFSC for purposes of evaluating, negotiating, structuring, closing and monitoring our investments. We are not a party to this Staffing Agreement and cannot assure stockholders that OFSC will fulfill its obligations under the agreement. If OFSC fails to perform, we cannot assure stockholders that OFS Advisor will enforce the Staffing Agreement or that such agreement will not be terminated by either party or that we will continue to have access to the investment professionals of OFSC and its affiliates or their information and deal flow. The investment committees that oversee our investment activities are provided by OFS Advisor under the Investment Advisory Agreement. The loss of any member of the Advisor Investment Committees or of other OFSC senior professionals could limit our ability to achieve our investment objective and operate as we anticipate. This could have a material adverse effect on our financial condition and results of operation. Our business model depends to a significant extent upon strong referral relationships with financial institutions, sponsors and investment professionals. Any inability of OFS Advisor to maintain or develop these relationships, or the failure of these relationships to generate investment opportunities, could adversely affect our business. We depend upon OFS Advisor to maintain relationships with financial institutions, sponsors and investment professionals, and we will continue to rely to a significant extent upon these relationships to provide us with potential investment opportunities. If OFS Advisor fails to maintain such relationships, or to develop new relationships with other sources of investment opportunities, we will not be able to grow our investment portfolio. In addition, individuals with whom the principals of OFS Advisor have relationships are not obligated to provide us with investment opportunities, and, therefore, we can offer no assurance that these relationships will generate investment opportunities for us in the future. Our financial condition and results of operation will depend on our ability to manage our business effectively. Our ability to achieve our investment objective and grow will depend on our ability to manage our business. This will depend, in turn, on the ability of the Advisor Investment Committees to identify, invest in and monitor companies that meet our investment criteria. The achievement of our investment objectives on a cost-effective basis will depend upon the Advisor Investment Committees’ ability to execute our investment process, their ability to provide competent, attentive and efficient services to us and, to a lesser extent, our access to financing on acceptable terms. OFS Advisor has substantial responsibilities under the Investment Advisory Agreement. OFS Advisor’s senior professionals and other personnel of OFS Advisor’s affiliates, including OFSC, may be called upon to provide managerial assistance to our portfolio companies. These activities may distract them or slow our rate of investment. Any failure to manage our business and our future growth effectively could have a material adverse effect on our business, financial condition and results of operations. To the extent PIK interest and PIK dividends constitute a portion of our income, we will be required to include such income in taxable and accounting income prior to receipt of cash representing such income. Our investments may include contractual PIK interest or PIK dividends, which represents contractual interest or dividends added to a loan balance or equity security and due at the end of such loan’s or equity security’s term. To the extent PIK interest and PIK dividends constitute a portion of our income, we will be exposed to typical risks associated with such income being required to be included in taxable and accounting income prior to receipt of cash. Such risks include: • The higher interest or dividend rates of PIK instruments reflect the payment deferral and increased risk associated with these instruments, and PIK instruments often represent a significantly higher risk than non-PIK instruments. • Even if the accounting conditions for income accrual are met, the borrower could still default when our actual collection is supposed to occur at the maturity of the obligation. • PIK instruments may have unreliable valuations because their continuing accruals require continuing judgments about the collectability of the deferred payments and the value of any associated collateral. PIK income may also create uncertainty about the source of our cash distributions. • For accounting purposes, any cash distributions to stockholders representing PIK income are not treated as coming from paid-in capital. As a result, despite the fact that a distribution representing PIK income could be paid out of amounts invested by our stockholders, the 1940 Act does not require that stockholders be given notice of this fact by reporting it as a return of capital. • PIK interest or dividends have the effect of generating investment income at a compounding rate, thereby further increasing the incentive fees payable to OFS Advisor. Similarly, all things being equal, the deferral associated with PIK interest or dividends also decreases the investment principal-to-value ratio at a compounding rate. A significant amount of our portfolio investments are recorded at fair value and OFS Advisor, our “valuation designee,” determines the fair value of our investments in good faith pursuant to Rule 2a-5 under the 1940 Act. As a result, there will be uncertainty as to the value of our portfolio investments and the participation of OFS Advisor’s professionals in our valuation process could result in a conflict of interest. Many of our portfolio investments take the form of securities that are not publicly traded and their fair value may not be readily determinable. In December 2020, the SEC adopted Rule 2a-5 under the 1940 Act (“Rule 2a-5”), which establishes requirements for good faith determinations of fair value, and addresses both the Board’s and the “valuation designee’s” roles and responsibilities relating to fair valuation. On September 7, 2022, pursuant to Rule 2a-5, our Board designated OFS Advisor, as valuation designee, to perform fair value determinations relating to our investments, for which market quotations are not readily available. In order for the Board to maintain oversight, OFS Advisor implemented the requirements as prescribed in Rule 2a-5. The determination of fair value and, consequently, the amount of unrealized gains and losses in our portfolio, are, to a significant degree, subjective and dependent on a valuation process undertaken by OFS Advisor and overseen by our Board. Valuation of certain investments will also be based, in part, upon third party valuation models which take into account various unobservable inputs. A majority of our investments are classified as Level 3 under ASC Topic 820. This means that our portfolio valuations are based on unobservable inputs and assumptions about how market participants would price the asset or liability in question. Inputs into the determination of fair value of our portfolio investments require significant management judgment and estimation. Even if observable market data is available, such information may be the result of consensus pricing information or broker quotes, which include a disclaimer that the broker would not be held to such a price in an actual transaction. The non-binding nature of consensus pricing and/or quotes accompanied by disclaimers materially reduces the reliability of such information. We presently retain the services of independent service providers to prepare the valuation of the majority of these securities. Certain factors that may be considered in determining the fair value of our investments include third-party yield benchmarks and comparison to publicly traded securities including such factors as yield, maturity and measures of credit quality, the enterprise value of a portfolio company, the nature and realizable value of any collateral, the portfolio company’s ability to make payments and its earnings and cash flow, the markets in which the portfolio company does business and other relevant factors. The models, information and/or underlying assumptions utilized by OFS Advisor will not always allow OFS Advisor to correctly capture the fair value of an asset. Because such valuations, and particularly valuations of securities that are not publicly traded, like those we hold, are inherently uncertain, they may fluctuate materially over short periods of time and may be based on estimates. OFS Advisor’s determinations of fair value may differ materially from the values that would have been used if an active public market for these securities existed. OFS Advisor’s determinations of the fair value of our investments have a material impact on our net earnings through the recording of unrealized appreciation or depreciation of investments and may cause our NAV on a given date to understate or overstate, possibly materially, the value that we may ultimately realize on one or more of our investments. The participation of OFS Advisor’s professionals in our valuation process could also result in a conflict of interest since OFS Advisor’s base management fee is based, in part, on the average value of our total assets (other than cash and cash equivalents but including assets purchased with borrowed amounts and including assets owned by any consolidated entity). We may finance our investments with borrowed money, which magnifies the potential for gain or loss on amounts invested and may increase the risk of investing in us. The use of leverage magnifies the potential for gain or loss on amounts invested. The use of leverage is generally considered a speculative investment technique and increases the risks associated with investing in our securities. We may pledge up to 100% of our assets and may grant a security interest in all of our assets, other than assets held in OFSCC-FS and SBIC I LP, under the terms of any debt instruments we may enter into with lenders. In addition, under the terms of any credit facility or other debt instrument we enter into, we are likely to be required by its terms to use the net proceeds of any investments that we sell to repay a portion of the amount borrowed under such facility or instrument before applying such net proceeds to any other uses. If the value of our assets decreases, leveraging would cause NAV to decline more sharply than it otherwise would have had we not leveraged, thereby magnifying losses or eliminating our equity stake in a leveraged investment. Similarly, any decrease in our revenue or income will cause our net income to decline more sharply than it would have had we not borrowed. Such a decline would also negatively affect our ability to make dividend payments on our common stock or preferred stock. Our ability to service our debt will depend largely on our financial performance and will be subject to prevailing economic conditions and competitive pressures. Moreover, because the base management fee payable to OFS Advisor is payable based on our total assets (other than cash and cash equivalents but including assets purchased with borrowed amounts and including assets owned by any consolidated entity), OFS Advisor has a financial incentive to cause us to incur leverage which may not be consistent with our stockholders’ interests. In addition, our common stockholders will bear the burden of any increase in our expenses as a result of our use of leverage, including interest expenses and any increase in the base management fee payable to OFS Advisor. On May 3, 2018, the Board, including a “required majority” (as such term is defined in Section 57(o) of the 1940 Act) of the Board, approved the application of a reduced 150% asset coverage ratio to us; therefore, provided certain conditions are met, we became subject to the reduced asset coverage ratio as of May 3, 2019. See “ Item 1A. Risk Factors—Risks Related to our Business and Structure—Because we received the approval of our Board, we became subject to 150% asset coverage effective May 3, 2019. ” As of December 31, 2023, our asset coverage ratio was 160%, excluding the debt held by SBIC I LP. The following table illustrates the effect of leverage on returns from an investment in our common stock assuming various annual returns, net of expenses. The calculations in the table below are hypothetical and actual returns may be higher or lower than those appearing in the table below. Assumed Return on Our Portfolio (Net of Expenses) Assumed Return on Portfolio (10)% (5)% 0% 5% 10% Corresponding return to common stockholder (1) (37.4)% (24.4)% (11.4)% 1.5% 14.5% (1) Assumes $420.3 million in investments at fair value, $302.4 million in outstanding debt, $162.0 million in net assets, and an average cost of funds of 6.12% as of December 31, 2023. Our investment portfolio must experience an annual return of 4.41% at least to cover interest payments on the outstanding debt. This example is for illustrative purposes only, and actual interest rates on and the amount of our borrowings are likely to fluctuate. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Borrowings” for additional information. Insufficient cash flows may increase our risk of default of our debt obligations, including under our Unsecured Notes and our BNP Facility. Any default under the agreements governing our indebtedness, including under our Unsecured Notes and our BNP Facility, that is not waived and the remedies sought by the holders of such indebtedness could make us unable to pay principal, premium, if any, and interest on our other debt obligations. If we are unable to generate sufficient cash flow and are otherwise unable to obtain funds necessary to meet required payments of principal, premium, if any, and interest on our indebtedness, or if we otherwise fail to comply with the various covenants, including financial and operating covenants, in the instruments governing our indebtedness, we could be in default under the terms of the agreements governing such indebtedness. Our ability to generate sufficient cash flows in the future is, to some extent, subject to general economic, financial, competitive, legislative and regulatory factors as well as other factors that are beyond our control. We cannot assure our stockholders that our business will generate cash flows from operations to meet the payment obligations of our debt obligations under our Unsecured Notes and our BNP Facility. Because we received the approval of our Board, we became subject to 150% asset coverage effective May 3, 2019. The 1940 Act generally prohibits a BDC from incurring indebtedness unless, immediately after such borrowing, it has an asset coverage for total borrowings of at least 200% (i.e., the amount of debt may not exceed 50% of the value of its assets). However, Section 61(a)(2) of the 1940 Act allows a BDC to increase the maximum amount of leverage it may incur from an asset coverage ratio of 200% to an asset coverage ratio of 150%, if certain requirements are met. On May 3, 2018, our Board approved the application of the reduced asset coverage ratio to us made available under Section 61(a)(2) of the 1940 Act. As a result, effective May 3, 2019, we were able to increase our leverage up to an amount that reduces our asset coverage ratio from 200% to 150% (i.e., the amount of debt may not exceed 66 2/3% of the value of our assets). Leverage magnifies the potential for loss on investments in our indebtedness and on invested equity capital. As we use leverage to partially finance our investments, our stockholders will experience increased risks of investing in our securities. If the value of our assets increases, then the additional leverage would cause the NAV attributable to our common stock to increase more sharply than it would have had we not increased our leverage. Conversely, if the value of our assets decreases, the additional leverage would cause NAV to decline more sharply than it otherwise would have had we not increased our leverage. Similarly, any increase in our income in excess of interest payable on the borrowed funds would cause our net investment income to increase more than it would without the additional leverage, while any decrease in our income would cause net investment income to decline more sharply than it would have had we not increased our leverage. Such a decline could negatively affect our ability to pay common stock dividends, scheduled debt payments or other payments related to our securities. Leverage is generally considered a speculative investment technique. See “Item 1A. Risk Factors—Risks Related to Our Business and Structure—We may finance our investments with borrowed money, which magnifies the potential for gain or loss on amounts invested and may increase the risk of investing in us.” In addition, the ability of BDCs to increase their leverage will increase the capital available to BDCs and thus competition for the investments that we seek to make. This may negatively impact pricing on the investments that we do make and adversely affect our net investment income and results of operations. Changes in interest rates will affect our cost of capital and net investment income. To the extent we borrow money or issue preferred stock to make investments, our net investment income will depend, in part, upon the difference between the rate at which we borrow funds or pay dividends on preferred stock and the rate at which we invest those funds. As a result, we can offer no assurance that a significant change in market interest rates will not have a material adverse effect on our net investment income in the event we use debt to finance our investments. In periods of elevated interest rates, our cost of funds would increase, which could reduce our net investment income. We may use interest rate risk management techniques in an effort to limit our exposure to interest rate fluctuations. Such techniques may include various interest rate hedging activities to the extent permitted by the 1940 Act. A rise in the general level of interest rates typically leads to higher interest rates applicable to our debt investments. Accordingly, an increase in interest rates may result in an increase of the amount of incentive fees payable to OFS Advisor. We may enter into reverse repurchase agreements, which are another form of leverage. We may enter into reverse repurchase agreements as part of our management of our temporary investment portfolio.

Risk [Text Block]									Risks Related to OFS Advisor and its Affiliates We have potential conflicts of interest related to obligations that OFS Advisor or its affiliates may have to other clients. OFS Advisor and its affiliates manage other assets, including those of other BDCs, registered investment companies, separately managed accounts, accounts for which OFS Advisor or its affiliates may serve as a sub-advisor and CLOs, and may manage other entities in the future. These other funds and entities may have similar or overlapping investment strategies. Our executive officers, directors and members of the Advisor Investment Committees serve as officers, directors or principals of entities that operate in the same or a related line of business as we do, or of investment funds or other investment vehicles managed by OFS Advisor or its affiliates. Accordingly, they may have obligations to investors in those entities, the fulfillment of which might not be in our or our stockholders’ best interests or may require them to devote time to services for other entities, which could interfere with the time available to provide services to us. For example, OFS Advisor currently serves as the investment adviser to HPCI, a non-traded BDC that invests in senior secured loans of middle-market companies in the United States, similar to those we target for investment, including first lien, second lien and unitranche loans as well as subordinated loans and, to a lesser extent, warrants and other equity securities. OFS Advisor also serves as the investment adviser to OCCI, a closed-end management investment company that primarily invests in CLO debt and subordinated securities. Therefore, many investment opportunities will satisfy the investment criteria for both HPCI and us and, in certain instances, investment opportunities may be appropriate for OCCI and us. HPCI operates as a distinct and separate entity and any investment in our common stock will not be an investment in HPCI. In addition, our executive officers serve in substantially similar capacities for HPCI and OCCI and certain of our independent directors serve in a similar capacity for HPCI or OCCI. Similarly, OFS Advisor and/or its affiliates may have other clients with, similar, different or competing investment objectives. In serving in these multiple capacities, our executive officers and directors, OFS Advisor and/or its affiliates, and members of the Advisor Investment Committees may have obligations to other clients or investors in those entities, the fulfillment of which may not be in the best interests of us or our stockholders. OFS Advisor and OFSAM Holdings have procedures and policies in place designed to manage the potential conflicts of interest between OFS Advisor’s fiduciary obligations to us and its fiduciary obligations to other clients. For example, such policies and procedures are designed to ensure that investment opportunities are allocated in a fair and equitable manner among us and other clients of OFS Advisor. An investment opportunity that is suitable for clients of OFS Advisor may not be capable of being shared among some or all of such clients due to the limited scale of the opportunity or other factors, including regulatory restrictions imposed by the 1940 Act. There can be no assurance that we will be able to participate in all investment opportunities that are suitable to us. OFS Advisor will seek to allocate investment opportunities among eligible accounts in a manner that is fair and equitable over time and consistent with its allocation policy. We have potential conflicts of interest related to the purchases and sales that OFS Advisor makes on our behalf and/or on behalf of Affiliated Accounts . Conflicts may arise when we make an investment in conjunction with an investment being made by Affiliated Accounts, or in a transaction where another Affiliated Account has already made an investment. Investment opportunities are, from time to time, appropriate for more than one Affiliated Account in the same, different or overlapping securities of a portfolio company’s capital structure. Conflicts arise in determining the terms of investments, particularly where these Affiliated Accounts may invest in different types of securities in a single portfolio company. Questions arise as to whether payment obligations and covenants should be enforced, modified or waived, or whether debt should be restructured, modified or refinanced. We may invest in debt and other securities of companies in which other Affiliated Accounts hold those same securities or different securities, including equity securities. In the event that we make such investments, our interests will at times conflict with the interests of such other Affiliated Accounts, particularly in circumstances where the underlying company is facing financial distress. Decisions about what action should be taken, particularly in troubled situations, raises conflicts of interest, including, among other things, whether or not to enforce claims, whether or not to advocate or initiate a restructuring or liquidation inside or outside of bankruptcy, and the terms of any work-out or restructuring. The involvement of multiple Affiliated Accounts at both the equity and debt levels could inhibit strategic information exchanges among fellow creditors, including among us and other Affiliated Accounts. In certain circumstances, we or other Affiliated Accounts may be prohibited from exercising voting or other rights and may be subject to claims by other creditors with respect to the subordination of their interest. For example, in the event that one Affiliated Account has a controlling or significantly influential position in a portfolio company, that Affiliated Account may have the ability to elect some or all of the board of directors of such a portfolio company, thereby controlling its policies and operations, including the appointment of management, future issuances of securities, payment of dividends, incurrence of debt and entering into extraordinary transactions. In addition, a controlling Affiliated Account is likely to have the ability to determine, or influence, the outcome of operational matters and to cause, or prevent, a change in control of such a portfolio company. Such management and operational decisions may, at times, be in direct conflict with us or other Affiliated Accounts that have invested in the same portfolio company that do not have the same level of control or influence over the portfolio company. If additional capital is necessary as a result of financial or other difficulties, or to finance growth or other opportunities, we or other Affiliated Accounts may or may not provide such additional capital, and if provided, each Affiliated Account will supply such additional capital in such amounts, if any, as determined by OFS Advisor and/or OFS Advisor’s affiliates. Investments by more than one Affiliated Account in a portfolio company also raises the risk of using assets of an Affiliated Account of OFS Advisor to support positions taken by other Affiliated Accounts, or that a client may remain passive in a situation in which it is entitled to vote. In addition, there may be differences in timing of entry into, or exit from, a portfolio company for reasons such as differences in strategy, existing portfolio or liquidity needs, different Affiliated Account mandates or fund differences, or different securities being held. These variations in timing may be detrimental to us. The application of our investment mandate as compared to investment mandates of other Affiliated Accounts and the policies and procedures of OFS Advisor and OFS Advisor's affiliates are expected to vary based on the particular facts and circumstances surrounding each investment by two or more Affiliated Accounts, in particular when those Affiliated Accounts are in different classes of an issuer’s capital structure (as well as across multiple issuers or borrowers within the same overall capital structure) and, as such, there may be a degree of variation and potential inconsistencies in the manner in which potential or actual conflicts are addressed. Our independent directors may face conflicts of interest related to their obligations to the Affiliated Funds for which they also serve as independent directors. All of the independent directors of our Board also serve as independent directors of the board of directors of HPCI or OCCI, Affiliated Funds managed by OFS Advisor. In their capacities as directors for an Affiliated Fund board, the independent directors have a duty to make decisions on behalf of that Affiliated Fund that are in the best interests of that Affiliated Fund and its stockholders. Accordingly, our independent directors may face conflicts of interest when making a decision on behalf of one Affiliated Fund that may not be in the best interest of the other Affiliated Fund(s). For example, the SEC has granted exemptive relief to us, OFS Advisor, HPCI, OCCI, and certain other of our affiliates to co-invest in certain transactions that would otherwise be prohibited by the 1940 Act. In accordance with that relief, the independent directors must make certain findings on behalf of each Affiliated Fund with respect to initial co-investment transactions, including that the terms of the proposed transaction, including the consideration to be paid, are reasonable and fair to the Affiliated Fund and its stockholders and do not involve overreaching in respect of the Affiliated Fund or its stockholders on the part of any of the other participants in the proposed transaction. Under such circumstances, the independent directors may face conflicts of interest when making these determinations on behalf of us, HPCI and OCCI. Members of the Advisor Investment Committees, OFS Advisor or its affiliates may, from time to time, possess material non-public information, limiting our investment discretion. OFSC senior professionals and members of the Advisor Investment Committees may serve as directors of, or in a similar capacity with, companies in which we invest, the securities of which are purchased or sold on our behalf. In the event that material nonpublic information is obtained with respect to such companies, or we become subject to trading restrictions under the internal trading policies of those companies or as a result of applicable law or regulations, we could be prohibited for a period of time from purchasing or selling the securities of such companies, and this prohibition may have an adverse effect on us and our stockholders. The valuation process for certain of our portfolio holdings may create a conflict of interest. Many of our portfolio investments are made in the form of securities that are not publicly traded. The fair value of securities and other investments that are not publicly traded may not be readily determinable. On September 7, 2022, pursuant to Rule 2a-5, our Board designated OFS Advisor as the valuation designee to perform fair value determinations relating to our investments. As valuation designee, OFS Advisor determines the fair value of our portfolio investments in good faith, and, as a result, there may be uncertainty as to the value of our portfolio investments. In addition, the members of our Board who are not independent directors have a substantial indirect pecuniary interest in OFS Advisor. The participation of OFS Advisor in our valuation process, and the indirect pecuniary interest in OFS Advisor by those members of our Board, could result in a conflict of interest since OFS Advisor’s base management fee is based, in part, on our total assets (other than cash and cash equivalents but including assets purchased with borrowed amounts and including assets owned by any consolidated entity). We may have additional conflicts related to other arrangements with OFS Advisor or its affiliates. We have entered into a license agreement with OFSAM under which OFSAM has granted us a non-exclusive, royalty-free license to use the name “OFS.” See “Item 1. Business—Management and Other Agreements—License Agreement.” In addition, we rent office space from a subsidiary of OFSAM and pay that subsidiary our allocable portion of overhead and other expenses incurred in performing its obligations under the Administration Agreement, such as rent and our allocable portion of the cost of our officers, including our chief executive officer, chief financial officer, chief compliance officer and chief accounting officer. This creates conflicts of interest that our Board must monitor. The Investment Advisory Agreement with OFS Advisor and the Administration Agreement with OFS Services were not negotiated on an arm’s length basis and may not be as favorable to us as if they had been negotiated with an unaffiliated third party. The Investment Advisory Agreement and the Administration Agreement were negotiated between related parties. Consequently, their terms, including fees payable to OFS Advisor, may not be as favorable to us as if they had been negotiated with an unaffiliated third party. In addition, we could choose not to enforce, or to enforce less vigorously, our rights and remedies under these agreements because of our desire to maintain our ongoing relationship with OFS Advisor, OFS Services and their respective affiliates. Any such decision, however, would breach our fiduciary obligations to our stockholders. Our ability to enter into transactions with our affiliates is restricted, which may limit the scope of investments available to us. BDCs generally are prohibited under the 1940 Act from knowingly participating in certain transactions with their affiliates without the prior approval of their independent directors and, in some cases, of the SEC. Those transactions include purchases from, sales to, and so-called “joint” transactions, in which a BDC and one or more of its affiliates engage in certain types of profit-making activities, with such affiliates. Any person that owns, directly or indirectly, five percent or more of a BDC’s outstanding voting securities will be considered an affiliate of the BDC for purposes of the 1940 Act, and a BDC generally is prohibited from engaging in purchases of assets from or sales of assets to or joint transactions with such affiliates, absent the prior approval of the BDC’s independent directors. Additionally, without the approval of the SEC, a BDC is prohibited from engaging in purchases of assets from, or sales of assets to or joint transactions with, the BDC’s officers, directors, and employees, and advisors (and its affiliates). BDCs may, however, invest alongside certain related parties or their respective other clients, in certain circumstances where doing so is consistent with current law and SEC staff interpretations. For example, a BDC may invest alongside such accounts consistent with guidance promulgated by the SEC staff permitting the BDC and such other accounts to purchase interests in a single class of privately placed securities so long as certain conditions are met, including that the BDC’s advisor, acting on the BDC’s behalf and on behalf of other clients, negotiates no term other than price. Co-investment with such other accounts is not permitted or appropriate under this guidance when there is an opportunity to invest in different securities of the same issuer or where the different investments could be expected to result in a conflict between the BDC’s interests and those of other accounts. The 1940 Act generally prohibits BDCs from making certain negotiated co-investments with certain affiliates absent an order from the SEC permitting the BDC to do so. On August 4, 2020, we received the Order from the SEC to permit us to co-invest in portfolio companies with Affiliated Funds subject to compliance with the Order. The Order superseded a previous order that we received on October 12, 2016 and provides us with greater flexibility to enter into co-investment transactions with Affiliated Funds. Pursuant to the Order, we are generally permitted to co-invest with Affiliated Funds if a “required majority” (as defined in Section 57(o) of the 1940 Act) of our independent directors make certain conclusions in connection with a co-investment transaction, including that (1) the terms of the transactions, including the consideration to be paid, are reasonable and fair to us and our stockholders and do not involve overreaching in respect of us or our stockholders on the part of any person concerned and (2) the transaction is consistent with the interests of our stockholders and is consistent with our investment objective and strategies. In addition, we may file an application for an amendment to our existing Order to permit us to participate in follow-on investments in our existing portfolio companies with private funds that do not hold any investments in such existing portfolio companies. However, if filed, there is no guarantee that such application will be granted. When we invest alongside clients of OFSAM Holdings and its affiliates or their respective other clients, OFS Advisor will, to the extent consistent with applicable law, regulatory guidance, and/or the Order, allocate investment opportunities in accordance with its allocation policy. Under this allocation policy, if two or more investment vehicles with similar or overlapping investment strategies are in their investment periods, an available opportunity will be allocated based on the provisions governing allocations of such investment opportunities in the relevant organizational, offering or similar documents, if any, for such investment vehicles. In the absence of any such provisions, OFS Advisor will consider the following factors and the weight that should be given with respect to each of these factors: • investment guidelines and/or restrictions, if any, set forth in the applicable organizational, offering or similar documents for the investment vehicles; • the status of tax restrictions and tests and other regulatory restrictions and tests; • risk and return profile of the investment vehicles; • suitability/priority of a particular investment for the investment vehicles; • if applicable, the targeted position size of the investment for the investment vehicles; • level of available cash for investment with respect to the investment vehicles; • total amount of funds committed to the investment vehicles; and • the age of the investment vehicles and the remaining term of their respective investment periods, if any. When not relying on the Order, priority as to opportunities will generally be given to clients that are in their “ramp-up” period, or the period during which the account has yet to reach sufficient scale such that its investment income covers its operating expenses, over the accounts that are outside their ramp-up period but still within their investment or re-investment periods. However, application of one or more of the factors listed above, or other factors determined to be relevant or appropriate, may result in the allocation of an investment opportunity to a fund no longer in its ramp-up period over a fund that is still within its ramp-up period. In situations where co-investment with other accounts is not permitted or appropriate, OFS Advisor will need to decide which account will proceed with the investment. The decision by OFS Advisor to allocate an opportunity to another entity could cause us to forego an investment opportunity that we otherwise would have made. These restrictions, and similar restrictions that limit our ability to transact business with our officers or directors or their affiliates, may limit the scope of investment opportunities that would otherwise be available to us. Our base management fee may induce OFS Advisor to cause us to incur leverage. Our base management fee is payable based upon our total assets, other than cash and cash equivalents but including assets purchased with borrowed amounts and including assets owned by any consolidated entity. This fee structure may encourage OFS Advisor to cause us to borrow money to finance additional investments. Under certain circumstances, the use of borrowed money may increase the likelihood of default, which would disfavor holders of our common stock. Given the subjective nature of the investment decisions made by OFS Advisor on our behalf, our Board may not be able to monitor this potential conflict of interest effectively. Our incentive fee may induce OFS Advisor to make certain investments, including speculative investments. The incentive fee payable by us to OFS Advisor may create an incentive for OFS Advisor to make investments on our behalf that are riskier or more speculative than would be the case in the absence of such compensation arrangement. The way in which the incentive fee payable to OFS Advisor is determined may encourage OFS Advisor to use leverage to increase the return on our investments. Under certain circumstances, the use of leverage may increase the likelihood of default, which would disfavor our stockholders. OFS Advisor receives an incentive fee based, in part, upon net capital gains realized on our investments. Unlike that portion of the incentive fee based on income, there is no hurdle rate applicable to the portion of the incentive fee based on net capital gains. As a result, OFS Advisor may have a tendency to invest more capital in investments that are likely to result in capital gains as compared to income producing securities. Such a practice could result in our investing in more speculative securities than would otherwise be the case, which could result in higher investment losses, particularly during economic downturns. We may invest, to the extent permitted by law, in the securities and instruments of other investment companies, including private funds, and, to the extent we so invest, will bear our ratable share of any such investment company’s expenses, including management and performance fees. We remain obligated to pay management and incentive fees to OFS Advisor with respect to the assets invested in the securities and instruments of other investment companies. With respect to each of these investments, each of our stockholders will bear his or her share of the management and incentive fee of OFS Advisor as well as indirectly bearing the management and performance fees and other expenses of any investment companies in which we invest. Our Board is charged with protecting our interests by monitoring how OFS Advisor addresses these and other conflicts of interest associated with its management services and compensation. While our Board is not expected to review or approve each borrowing or incurrence of leverage, our independent directors will periodically review OFS Advisor’s services and fees. In connection with these reviews, our independent directors will consider whether our fees and expenses (including those related to leverage) remain appropriate. Our incentive fee structure may create incentives for OFS Advisor that are not fully aligned with the interests of our stockholders. In the course of our investing activities, we will pay management and incentive fees to OFS Advisor. The base management fee is based on our total assets (other than cash and cash equivalents, but including assets purchased with borrowed amounts and including assets owned by any consolidated entity). As a result, investors in our common stock will invest on a “gross” basis and receive distributions on a “net” basis after expenses, resulting in a lower rate of return than one might achieve through direct investments. Because these fees are based on our total assets, other than cash and cash equivalents but including assets purchased with borrowed amounts and including any assets owned by any consolidated entity, OFS Advisor will benefit when we incur debt or use leverage. Our Board is charged with protecting our interests by monitoring how OFS Advisor addresses these and other conflicts of interest associated with its management services and compensation. While our Board is not expected to review or approve each borrowing or incurrence of leverage, our independent directors will periodically review OFS Advisor’s services and fees as well as its portfolio management decisions and portfolio performance. In connection with these reviews, our independent directors will consider whether our fees and expenses (including those related to leverage) remain appropriate. As a result of this arrangement, OFS Advisor or its affiliates may from time to time have interests that differ from those of our stockholders, giving rise to a conflict. We may pay an incentive fee on income we do not receive in cash. The part of the incentive fee payable to OFS Advisor that relates to our pre-incentive fee net investment income is computed and paid on income that may include interest income that has been accrued but not yet received in cash. This fee structure may be considered to involve a conflict of interest for OFS Advisor to the extent that it may encourage OFS Advisor to favor debt financings that provide for deferred interest, rather than current cash payments of interest. OFS Advisor may have an incentive to invest in deferred interest securities in circumstances where it would not have done so but for the opportunity to continue to earn the incentive fee even when the issuers of the deferred interest securities would not be able to make actual cash payments to us on such securities. This risk could be increased because OFS Advisor is not obligated to reimburse us for any incentive fees received even if we subsequently incur losses or never receive previously accrued deferred income in cash. OFS Advisor’s liability is limited under the Investment Advisory Agreement, and we have agreed to indemnify OFS Advisor against certain liabilities, which may lead OFS Advisor to act in a riskier manner on our behalf than it would when acting for its own account. Under the Investment Advisory Agreement, OFS Advisor will not assume any responsibility to us other than to render the services called for under that agreement, and it will not be responsible for any action of our Board in following or declining to follow OFS Advisor’s advice or recommendations. Under the terms of the Investment Advisory Agreement, OFS Advisor and its affiliates, and its and their respective officers, directors, members, managers, partners, stockholders and employees, will not be liable to us or any subsidiary of ours, or our or their respective officers, directors, members, managers, partners, stockholders or employees, for acts or omissions performed in accordance with and pursuant to the Investment Advisory Agreement, except those resulting from acts constituting gross negligence, willful misconduct, bad faith or reckless disregard of such person’s duties under the Investment Advisory Agreement. In addition, we have agreed to indemnify OFS Advisor and its affiliates, and its and their respective officers, directors, members, managers, partners, stockholders and employees, from and against any claims or liabilities, including reasonable legal fees and other expenses reasonably incurred, arising out of or in connection with our business and operations or any action taken or omitted on our behalf pursuant to authority granted by the Investment Advisory Agreement, except where attributable to gross negligence, willful misconduct, bad faith or reckless disregard of such person’s duties under the Investment Advisory Agreement. These protections may lead OFS Advisor to act in a riskier manner when acting on our behalf than it would when acting for its own account. OFS Advisor can resign on 60 days’ notice, and we may not be able to find a suitable replacement within that time, resulting in a disruption in our operations that could adversely affect our financial condition, business and results of operations. OFS Advisor has the right, under the Investment Advisory Agreement, to resign at any time upon not less than 60 days’ written notice, whether we have found a replacement or not. If OFS Advisor resigns, we may not be able to find a new investment advisor or hire internal management with similar expertise and the ability to provide the same or equivalent services on acceptable terms within 60 days, or at all. If we are unable to do so quickly, our operations are likely to experience a disruption, our financial condition, business and results of operations, as well as our ability to pay distributions, are likely to be adversely affected and the value of our shares may decline. In addition, the coordination of our internal management and investment activities is likely to suffer if we are unable to identify and reach an agreement with a single institution or group of executives having the expertise possessed by the OFS Advisor and its affiliates. Even if we are able to retain comparable management, whether internal or external, the integration of such management and their lack of familiarity with our investment objectives may result in additional costs and time delays that may adversely affect our financial condition, business and results of operations. OFS Services can resign from its role as our Administrator under the Administration Agreement, and we may not be able to find a suitable replacement, resulting in a disruption in our operations that could adversely affect our financial condition, business and results of operations. OFS Services has the right to resign under the Administration Agreement, whether we have found a replacement or not. If OFS Services resigns, we may not be able to find a new administrator or hire internal management with similar expertise and the ability to provide the same or equivalent services on acceptable terms, or at all. If we are unable to do so quickly, our operations are likely to experience a disruption, our financial condition, business and results of operations, as well as our ability to pay distributions, are likely to be adversely affected and the value of our shares may decline. In addition, the coordination of our internal management and administrative activities is likely to suffer if we are unable to identify and reach an agreement with a service provider or individuals with the expertise possessed by OFS Services. Even if we are able to retain a comparable service provider or individuals to perform such services, whether internal or external, their integration into our business and lack of familiarity with our investment objectives may result in additional costs and time delays that may adversely affect our financial condition, business and results of operations.

General Description of Registrant [Abstract]
Risk [Text Block]									Risks Related to BDCs Regulations governing our operation as a BDC affect our ability to and the way in which we raise additional capital. As a BDC, we will need to raise additional capital, which will expose us to risks, including the typical risks associated with leverage. We may issue debt securities or preferred stock and/or borrow money from banks or other financial institutions, which we refer to collectively as “senior securities,” up to the maximum amount permitted by the 1940 Act. Under the provisions of the 1940 Act, we are permitted as a BDC to issue senior securities in amounts such that our asset coverage ratio, as defined in the 1940 Act, equals at least 150% of gross assets less all liabilities and indebtedness not represented by senior securities, after each issuance of senior securities. If the value of our assets declines, we may be unable to satisfy this test. If that happens, we may be required to sell a portion of our investments and, depending on the nature of our leverage, repay a portion of our indebtedness at a time when such sales may be disadvantageous. Also, any amounts that we use to service our indebtedness would not be available for distributions to our common stockholders. If we issue senior securities, we will be exposed to typical risks associated with leverage, including an increased risk of loss. On May 3, 2018, the Board, including a "required majority" (as such item is determined in section 57(o) of the 1940 Act) of the Board, approved the application of a reduced 150% asset coverage ratio to us and, as a result, the reduced asset coverage ratio applicable to us was decreased from 200% to 150% effective May 3, 2019. See " Item 1A. Risk Factors—Risks Related to our Business and Structure—Because we received the approval of our Board, we became subject to 150% asset coverage effective May 3, 2019. " As of December 31, 2023, we had $302.4 million of debt outstanding. Our ability to incur additional debt and remain in compliance with the asset coverage test will be limited. We may seek an additional credit facility to finance investments or for working capital requirements. There can be no assurance that we will be able to obtain such financing on favorable terms or at all. If we issue preferred stock, the preferred stock would rank “senior” to common stock in our capital structure, preferred stockholders would have separate voting rights on certain matters and might have other rights, preferences or privileges more favorable than those of our common stockholders, and the issuance of preferred stock could have the effect of delaying, deferring or preventing a transaction or a change of control that might involve a premium price for holders of our common stock or otherwise be in our stockholders’ best interest. Holders of our common stock will directly or indirectly bear all of the costs associated with offering and servicing any preferred stock that we issue. In addition, any interests of preferred stockholders may not necessarily align with the interests of holders of our common stock and the rights of holders of shares of preferred stock to receive dividends would be senior to those of holders of shares of our common stock. We are not generally able to issue and sell our common stock at a price below NAV per share. We may, however, sell our common stock, or warrants, options or rights to acquire our common stock, at a price below the then-current NAV per share of our common stock if our Board determines that such sale is in the best interests of us and our stockholders, and if our stockholders approve any such sale. In any such case, the price at which our securities are to be issued and sold may not be less than a price that, in the determination of our Board, closely approximates the market value of such securities (less any distributing commission or discount). On July 19, 2023, our stockholders approved a proposal that authorizes us to issue shares of our common stock at a price below our current NAV, subject to certain limitations, for up to 12 months from such approval. If we raise additional funds by issuing common stock or senior securities convertible into, or exchangeable for, our common stock, then the percentage ownership of our stockholders at that time will decrease, and our stockholders might experience dilution. Our ability to invest in public companies may be limited in certain circumstances. To maintain our status as a BDC, we are not permitted to acquire any assets other than “qualifying assets” specified in the 1940 Act unless, at the time the acquisition is made, at least 70% of our assets, as defined by the 1940 Act, are qualifying assets (with certain limited exceptions). Subject to certain exceptions for follow-on investments and distressed companies, an investment in an issuer that has outstanding securities listed on a national securities exchange may be treated as a qualifying asset only if such issuer has a common equity market capitalization that is less than $250 million at the time of such investment and meets the other specified requirements. If we do not invest a sufficient portion of our assets in qualifying assets, we could fail to continue to qualify as a BDC or be precluded from investing according to our current business strategy. As a BDC, we may not acquire any assets other than “qualifying assets” unless, at the time of and after giving effect to such acquisition, at least 70% of our assets, as defined by the 1940 Act, are qualifying assets. We believe that most of the investments that we may acquire in the future will constitute qualifying assets. However, we may be precluded from investing in what we believe are attractive investments if such investments are not qualifying assets for purposes of the 1940 Act. If a sufficient portion of our assets are not qualifying assets, we could violate the 1940 Act provisions applicable to BDCs. As a result of such violation, specific rules under the 1940 Act could prevent us, for example, from making follow-on investments in existing portfolio companies (which could result in the dilution of our position) or could require us to dispose of investments at inappropriate times in order to come into compliance with the 1940 Act. If we need to dispose of such investments quickly, it could be difficult to dispose of such investments on favorable terms. We may not be able to find a buyer for such investments and, even if we do find a buyer, we may have to sell the investments at a substantial loss. Any such outcomes would have a material adverse effect on our business, financial condition and results of operations. If we do not maintain our status as a BDC, we would be subject to regulation as a registered closed-end investment company under the 1940 Act. As a registered closed-end fund, we would be subject to substantially more regulatory restrictions under the 1940 Act which would significantly decrease our operating flexibility.
Risks Related To Investments [Member]
General Description of Registrant [Abstract]
Risk [Text Block]									Risks Related to Our Investments Economic recessions or downturns could impair our portfolio companies and harm our operating results. Many of our portfolio companies are susceptible to economic slowdowns or recessions and may be unable to repay our loans during these periods. Therefore, our non-performing assets are likely to increase and the value of our portfolio is likely to decrease during these periods. Adverse economic conditions may decrease the value of collateral securing some of our loans and the value of our equity investments. Economic slowdowns or recessions could lead to financial losses in our portfolio and a decrease in revenues, net income and assets. Unfavorable economic conditions also could increase our funding costs, limit our access to the capital markets or result in a decision by lenders not to extend credit to us. These events could prevent us from increasing our investments and harm our operating results. A portfolio company’s failure to satisfy financial or operating covenants imposed by us or other lenders could lead to defaults and, potentially, termination of its loans and foreclosure on its assets, which could trigger cross-defaults under other agreements and jeopardize our portfolio company’s ability to meet its obligations under the debt securities that we hold. We may incur expenses to the extent necessary to seek recovery upon default or to negotiate new terms with a defaulting portfolio company. In addition, lenders in certain cases can be subject to lender liability claims for actions taken by them when they become too involved in the borrower’s business or exercise control over a borrower. It is possible that we could become subject to a lender liability claim, including as a result of actions taken if we render significant managerial assistance to the borrower. Furthermore, if one of our portfolio companies were to file for bankruptcy protection, even though we may have structured our investment as senior secured debt, depending on the facts and circumstances, including the extent to which we provided managerial assistance to that portfolio company, a bankruptcy court might re-characterize our debt holding and subordinate all or a portion of our claim to claims of other creditors. Our investments in the debt instruments of leveraged portfolio companies may be risky and, due to the significant volatility of such companies, we could lose all or part of our investment in bankruptcy proceedings or otherwise. Investments in leveraged companies involves a number of significant risks. Leveraged companies in which we invest may have limited financial resources and may be unable to meet their obligations under their debt securities that we hold due to the significant volatility of such companies. Negative developments may be accompanied by deterioration of the value of any collateral and a reduction in the likelihood of our realizing any guarantees that we may have obtained in connection with our investment. Such developments may ultimately result in the leveraged companies in which we invest entering into bankruptcy proceedings, which have a number of inherent risks. Many events in a bankruptcy proceeding are the product of contested matters and adversary proceedings and are beyond the control of creditors. A bankruptcy filing by an issuer may adversely and permanently affect the issuer. If the proceeding is converted to a liquidation, the value of the issuer may not equal the liquidation value that was believed to exist at the time of the investment. The duration of a bankruptcy proceeding is also difficult to predict, and a creditor’s return on investment can be adversely affected by delays until the plan of reorganization or liquidation ultimately becomes effective. The administrative costs in connection with a bankruptcy proceeding are frequently high and would be paid out of the debtor’s estate prior to any return to creditors. Because the standards for classification of claims under bankruptcy law are vague, our influence with respect to the class of securities or other obligations we own may be lost by increases in the number and amount of claims in the same class or by different classification and treatment. In the early stages of the bankruptcy process, it is difficult to estimate the extent of, or even to identify, any contingent claims that might be made. Certain claims that have priority by law (for example, claims for taxes) may be substantial. In addition, our subordinated loans are generally subordinated to senior loans and are generally unsecured, other creditors may rank senior to us in the event of a bankruptcy proceeding. Our investments in debt instruments may include “covenant-lite” loans. Covenants are contractual restrictions that lenders place on companies to limit the corporate actions a company may pursue. Generally, the loans in which we expect to invest will have financial maintenance covenants, which are used to proactively address materially adverse changes in a portfolio company’s financial performance. However, we may invest in “covenant-lite” loans. We use the term “covenant-lite” to refer generally to loans that do not have a complete set of financial maintenance covenants. Generally, “covenant-lite” loans provide borrower companies more freedom to negatively impact lenders because their financial covenants are incurrence-based, which means they are only tested and can only be breached following an affirmative action of the borrower, rather than by a deterioration in the borrower’s financial condition. Accordingly, to the extent we invest in “covenant-lite” loans, we may have fewer rights against a borrower and may have a greater risk of loss on such investments as compared to investments in or exposure to loans with financial maintenance covenants. Inflation may adversely affect the business, results of operations and financial condition of our portfolio companies. Certain of our portfolio companies may be impacted by the effects of inflation. If such portfolio companies are unable to pass any increases in their costs along to their customers, it could adversely affect their results and impact their ability to pay interest and principal on our loans. In addition, any projected future decreases in our portfolio companies’ operating results due to the effects of inflation could adversely impact the fair value of those investments. Any decreases in the fair value of our investments could result in future unrealized losses and therefore reduce our net assets resulting from operations. Any of our portfolio companies operating in the Health Care and Social Assistance industry are subject to extensive government regulation and certain other risks particular to that industry. We invest in companies in the Health Care and Social Assistance industry. Our investments in portfolio companies that operate in this sector are subject to significant risks particular to that industry. The laws and rules governing the business of healthcare companies and interpretations of those laws and rules are subject to frequent change. Broad latitude is given to the agencies administering those regulations. Existing or future laws and rules could force our portfolio companies engaged in healthcare to change how they do business, restrict revenue, increase costs, change reserve levels and change business practices. Healthcare companies often must obtain and maintain regulatory approvals to market many of their products and change prices for certain regulated products. Delays in obtaining or failing to obtain or maintain these approvals could reduce revenue or increase costs. Policy changes on the local, state and federal levels, such as the expansion of the government’s role in the healthcare arena and alternative assessments and tax increases specific to the healthcare industry or healthcare products as part of federal health care reform initiatives, could fundamentally change the dynamics of the healthcare industry. In particular, health insurance reform could have a significant effect on our portfolio companies in this industry, and may force our portfolio companies in this industry to change how they do business. We can give no assurance that our portfolio companies will be able to adapt successfully in response to these changes. Portfolio companies in the Health Care and Social Assistance industry may also have a limited number of suppliers of necessary components or a limited number of manufacturers for their products, and therefore face a risk of disruption to their manufacturing process if they are unable to find alternative suppliers when needed. Any of these factors could materially adversely affect the operations of a portfolio company in this industry and, in turn, impair our ability to timely collect principal and interest payments owed to us. The documents governing the loans to our portfolio companies and the loans underlying our CLO investments may allow for “priming transactions.” The documents governing the loans to our portfolio companies and the loans underlying our CLO investments may allow for “priming transactions,” where majority lenders or debtors can amend the documents to the detriment of other lenders, in order to move collateral, or in order to facilitate capital outflow to other parties/subsidiaries in a capital structure, any of which may adversely affect our rights and security priority with respect to such loans. Our investments in private and middle-market portfolio companies are generally considered lower credit quality obligations, are risky, and we could lose all or part of our investment. Investments in private and middle-market companies involve a number of significant risks. Generally, little public information exists about these companies, and we rely on the ability of OFS Advisor’s investment professionals to obtain adequate information to evaluate the potential returns from investing in these companies. If we are unable to uncover all material information about these companies, we may not make fully informed investment decisions, and we may lose money on our investments. Middle-market companies may have limited financial resources and may be unable to meet their obligations under their debt securities that we hold, which may be accompanied by a deterioration in the value of any collateral and a reduction in the likelihood of our realizing any guarantees we may have obtained in connection with our investment. Such companies typically have shorter operating histories, narrower product lines and smaller market shares than larger businesses, which tend to render them more vulnerable to competitors’ actions, market conditions and general economic downturns. Middle-market companies are more likely to be considered lower grade investments, commonly called “junk bonds,” which are either rated below investment grade by one or more nationally-recognized statistical rating agencies at the time of investment, or may be unrated but determined by OFS Advisor to be of comparable quality. Lower grade securities or comparable unrated securities are considered predominantly speculative regarding the issuer’s ability to pay interest and principal, and are susceptible to default or decline in market value due to adverse economic and business developments. The market values for lower grade debt tend to be very volatile and are less liquid than investment grade securities. For these reasons, an investment in the Company is subject to the following specific risks: (i) increased price sensitivity due to a deteriorating economic environment; (ii) greater risk of loss due to default or declining credit quality; (iii) the inability to make interest and/or principal payments due to adverse company specific events; and (iv) depression of the price and liquidity of lower grade securities if a negative perception of the lower grade debt market develops. This negative perception could last for a significant period of time. Additionally, middle-market companies are more likely to depend on the management talents and efforts of a small group of persons. Therefore, the death, disability, resignation or termination of one or more of these persons could have a material adverse impact on our portfolio companies and, in turn, on us. Middle-market companies may also be parties to litigation and may be engaged in rapidly changing businesses with products subject to a substantial risk of obsolescence. In addition, our executive officers, directors and OFS Advisor may, in the ordinary course of business, be named as defendants in litigation arising from our investments in middle-market companies. Investments in equity securities involve a substantial degree of risk. We have purchased, and may purchase in the future, common stock and other equity securities, including warrants, in various portfolio companies. Although equity securities historically have generated higher average total returns than debt securities over the long term, equity securities may experience more volatility in those returns than debt securities. The equity securities we acquire may fail to appreciate, decline in value or lose all value, and our ability to recover our investment will depend on the portfolio company’s success. Investments in equity securities involve a number of significant risks, including the risk of further dilution in the event the portfolio company issues additional securities. Investments in preferred securities involve special risks, such as the risk of deferred distributions, illiquidity and limited voting rights. Our equity ownership in a portfolio company may represent a control investment. Our ability to exit a control investment in a timely manner could result in a realized loss on the investment. If we obtain a control investment in a portfolio company, our ability to divest ourselves from a debt or equity investment could be restricted due to illiquidity in a private stock, limited trading volume on a public company’s stock, inside information on a company’s performance, insider blackout periods, or other factors that could prohibit us from disposing of the investment as we would if it were not a control investment. Additionally, we may choose not to take certain actions to protect a debt investment in a control investment portfolio company. As a result, we could experience a decrease in the value of our portfolio company holdings and potentially incur a realized loss on the investment. Our investments in Structured Finance Securities carry additional risks to the risks associated with investing in private debt. In addition to the general risks associated with debt securities and structured products discussed herein, CLOs carry additional risks, including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) the possibility that the investments in CLOs are subordinate to other classes or tranches thereof; (iv) the potential of spread compression in the underlying loans of the CLO, which could reduce credit enhancement in the CLOs; and (v) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results. CLO equity securities that we may acquire are subordinated to more senior tranches of CLO debt. CLO equity securities are subject to increased risks of default relative to the holders of superior priority interests in the same securities. In addition, at the time of issuance, CLO equity securities are under-collateralized in that the liabilities of a CLO at inception exceed its total assets. When we invest in a CLO, we may be in a first loss or subordinated position with respect to realized losses on the CLO’s assets. In addition, we may recognize phantom taxable income from our investments in the subordinated tranches of CLOs. Between the closing date and the effective date of a CLO, the CLO collateral manager will generally expect to purchase additional collateral obligations for the CLO. During this period, the price and availability of these collateral obligations may be adversely affected by a number of market factors, including price volatility and availability of investments suitable for the CLO, which could hamper the ability of the collateral manager to acquire a portfolio of collateral obligations that will satisfy specified concentration limitations and allow the CLO to reach the initial par amount of collateral prior to the effective date. An inability or delay in reaching the target initial par amount of collateral may adversely affect the timing and amount of interest or principal payments received by the holders of the CLO debt securities and distributions of the CLO on equity securities and could result in early redemptions which may cause CLO debt and equity investors to receive less than the face value of their investment. In addition, the portfolios of certain CLOs in which we may invest may contain “covenant-lite” loans. Accordingly, to the extent we are exposed to “covenant-lite” loans, we may have a greater risk of loss on such investments as compared to investments in or exposure to loans with financial maintenance covenants. Separately, we may incur expenses to the extent necessary to seek recovery upon default or to negotiate new terms, which may include the waiver of certain financial covenants, with a defaulting CLO or any other investment we may make. If any of these occur, it could adversely affect our operating results and cash flows. Our CLO investments will be exposed to leveraged credit risk. If a CLO does not meet certain minimum collateral value ratios and/or interest coverage ratios, primarily due to senior secured loan defaults, then cash flow that otherwise would have been available to pay us distributions may instead be used to redeem any senior notes or to purchase additional senior secured loans, until the ratios again exceed the minimum required levels or senior notes are repaid in full. Our investments in Structured Finance Securities are more likely to suffer a loss of all or a portion of their value in the event of a default. From time to time, we invest in Structured Finance Securities that comprise the equity tranche of CLOs, which are junior in priority of payment and are subject to certain payment restrictions generally set forth in an indenture governing such investments. In addition, Structured Finance Securities generally do not benefit from any creditors’ rights or ability to exercise remedies under the indenture governing such investments. Structured Finance Securities are not guaranteed by another party and are subject to greater risk than the secured notes issued by the CLO. CLOs are typically highly levered, utilizing up to approximately 9-13 times leverage, and therefore Structured Finance Securities are subject to a risk of total loss. There can be no assurance that distributions on the assets held by the CLO will be sufficient to make any distributions or that the yield on the Structured Finance Securities will meet our expectations. CLOs generally may make payments on Structured Finance Securities only to the extent permitted by the payment priority provisions of an indenture governing the notes issued by the CLO. CLO indentures generally provide that principal payments on Structured Finance Securities may not be made on any payment date unless all amounts owing under secured notes are paid in full. We will have no influence on the management of underlying investments managed by non-affiliated third-party CLO collateral managers. We are not responsible for, and have no influence over, the asset management of the portfolios underlying the Structured Finance Securities we hold as those portfolios are managed by non-affiliated third-party CLO collateral managers. Similarly, we are not responsible for, and have no influence over, the day-to-day management, administration or any other aspect of the issuers of the CLOs. As a result, the values of the portfolios underlying our Structured Finance Securities could decrease as a result of decisions made by third-party CLO collateral managers. We may suffer a loss if a portfolio company defaults on a loan and the underlying collateral is not sufficient. We will, at times, take a security interest in the available assets of our portfolio companies, including the equity interests of their subsidiaries and, in some cases, the equity interests of our portfolio companies held by their stockholders. In the event of a default by a portfolio company on a secured loan, we will only have recourse to the assets collateralizing the loan. There is a risk that the collateral securing our loans may: (i) decrease in value over time; (ii) be difficult to sell in a timely manner; (iii) be difficult to appraise; and (iv) fluctuate in value based upon the success or deterioration of the business and market conditions, including as a result of the inability of a portfolio company to raise additional capital. Additionally, in the case of certain of our investments, we do not have a first lien position on the collateral and may not receive the full value of the collateral upon liquidation. If the underlying collateral value is less than the loan amount, we will suffer a loss. In the event of bankruptcy of a portfolio company, we may not have full recourse to its assets in order to satisfy our loan, or our loan may be subject to equitable subordination. In addition, certain of our loans are subordinate to other debt of the portfolio company. If a portfolio company defaults on our loan or on debt senior to our loan, or in the event of a portfolio company bankruptcy, our loan will be satisfied only after the senior debt receives payment. Where debt senior to our loan exists, the presence of inter-creditor arrangements may limit our ability to amend our loan documents, assign our loans, accept prepayments, exercise our remedies (through “standstill” periods) and control decisions made in bankruptcy proceedings relating to the portfolio company. Bankruptcy and portfolio company litigation can significantly increase collection losses and the time needed for us to acquire the underlying collateral in the event of a default, during which time the collateral may decline in value, causing us to suffer losses. Borrowers of Broadly Syndicated Loans may be permitted to designate unrestricted subsidiaries under the terms of their financing agreements, which would exclude such unrestricted subsidiaries from restrictive covenants under the financing agreement with the borrower. This would allow the borrower to take various actions with respect to the unrestricted subsidiary including, among other things, incur debt, grant security on its assets, sell assets, pay dividends or distribute shares of the unrestricted subsidiary to the borrower’s stockholders. Any of these actions could increase the amount of leverage that the borrower is able to incur and increase the risk involved in our investments in Broadly Syndicated Loans accordingly. If the value of collateral underlying our loan declines or interest rates increase during the term of our loan, a portfolio company may not be able to obtain the necessary funds to repay our loan at maturity through refinancing. Decreasing collateral value and/or increasing interest rates may hinder a portfolio company’s ability to refinance our loan because the underlying collateral cannot satisfy the debt service coverage requirements necessary to obtain new financing. If a borrower is unable to repay our loan at maturity, we could suffer a loss which may adversely impact our financial performance. The lack of liquidity in our investments may adversely affect our business. All of our assets are presently invested in illiquid securities, and a substantial portion of our investments in leveraged companies is subject to legal and other restrictions on resale or is otherwise less liquid than more broadly traded public securities. The illiquidity of these investments may make it difficult for us to sell such investments if the need arises. In addition, if we are required to liquidate all or a portion of our portfolio quickly, we may realize significantly less than the value at which we have previously recorded these investments. We may also face other restrictions on our ability to liquidate an investment in a portfolio company to the extent that we, OFS Advisor, OFSAM Holdings or any of its other affiliates have material nonpublic information regarding such portfolio company. Price declines and illiquidity in the corporate debt markets may adversely affect the fair value of our portfolio investments, reducing our NAV through increased net unrealized depreciation. As a BDC, we are required to carry our investments at market value or, if no market value is ascertainable, at fair value as determined in good faith by OFS Advisor, as our valuation designee. As part of the valuation process, OFS Advisor may take into account the following types of factors, if relevant, in determining the fair value of our investments: • a comparison of the portfolio company’s securities to publicly traded securities; • the enterprise value of a portfolio company; • the nature and realizable value of any collateral; • the portfolio company’s ability to make payments and its earnings and discounted cash flow; • the markets in which the portfolio company does business; and • changes in the interest rate environment and the credit markets generally that may affect the price at which similar investments may be made in the future and other relevant factors. When an external event such as a purchase transaction, public offering or subsequent equity sale occurs, OFS Advisor will use the pricing indicated by the external event to corroborate the valuation. We will record decreases in the market values or fair values of our investments as unrealized depreciation. Declines in prices and liquidity in the corporate debt markets may result in significant net unrealized depreciation in our portfolio. The effect of all of these factors on our portfolio may reduce our NAV by increasing net unrealized depreciation in our portfolio. Depending on market conditions, we could incur substantial realized losses and may suffer additional unrealized losses in future periods, which could have a material adverse effect on our business, financial condition and results of operations. We are a non-diversified management investment company within the meaning of the 1940 Act, and therefore we are not limited by the 1940 Act with respect to the proportion of our assets that may be invested in securities of a single issuer. We are classified as a non-diversified management investment company within the meaning of the 1940 Act, which means that we are not limited by the 1940 Act with respect to the proportion of our assets that we may invest in securities of a single issuer. To the extent that we assume large positions in the securities of a small number of issuers, our NAV may fluctuate to a greater extent than that of a diversified investment company as a result of changes in the financial condition or the market’s assessment of the issuer. We may also be more susceptible to any single economic or regulatory occurrence than a diversified investment company. Beyond our asset diversification requirements as a RIC under the Code, we do not have fixed guidelines for diversification, and our investments could be concentrated in relatively few portfolio companies. Our portfolio may be concentrated in a limited number of portfolio companies and industries, which will subject us to a risk of significant loss if any of these companies default on their obligations under any of their debt instruments or if there is a downturn in a particular industry. Although we believe our portfolio is well-diversified across companies and industries, our portfolio is, and may in the future be, concentrated in a limited number of portfolio companies and industries. As a result, the aggregate returns we realize may be significantly adversely affected if a small number of investments perform poorly or if we need to write down the value of any one investment. Additionally, while we are not targeting investments in any specific industries, our investments may be concentrated in relatively few industries. As a result, a downturn in any particular industry in which we are invested could also significantly impact the aggregate returns we realize. As of December 31, 2023, our common equity investment in Pfanstiehl Holdings, Inc., a global manufacturer of high-purity pharmaceutical ingredients, based on its fair value of $70.9 million, $70.7 million of which represents unrealized appreciation, accounted for 17% of our total investment portfolio at fair value, or 44% of total net assets. A deterioration in this portfolio company’s operating performance or other factors underlying the valuation of this investment could have a material impact on our NAV. Our failure to make follow-on investments in our portfolio companies could impair the value of our portfolio. Following an initial investment in a portfolio company, we may make additional investments in that portfolio company as “follow-on” investments, in seeking to: • increase or maintain, in whole or in part, our position as a creditor or equity ownership percentage in a portfolio company; • exercise warrants, options or convertible securities that were acquired in the original or subsequent financing; or • preserve or enhance the value of our investment. We have discretion to make follow-on investments, subject to the availability of capital resources. The failure on our part to make follow-on investments may, in some circumstances, jeopardize the continued viability of a portfolio company and our initial investment, or may result in a missed opportunity for us to increase our participation in a successful operation. Even if we have sufficient capital to make a desired follow-on investment, we may elect not to make a follow-on investment because: (i) we may not want to increase our level of risk; (ii) we prefer other opportunities; or (iii) we are inhibited by compliance with BDC requirements or the desire to maintain our RIC status. Our ability to make follow-on investments may also be limited by OFS Advisor’s allocation policy. Because we generally do not hold controlling equity interests in our portfolio companies, we may not be able to exercise control over our portfolio companies or prevent decisions by management of our portfolio companies that could decrease the value of our investments. We generally do not hold controlling equity positions in our portfolio companies. For portfolio companies in which we do not hold a controlling equity interest, we are subject to the risk that a portfolio company may make business decisions with which we disagree, and that the management and/or stockholders of a portfolio company may take risks or otherwise act in ways that are adverse to our interests. Due to the lack of liquidity of the debt and equity investments that we typically hold in our portfolio companies, we may not be able to dispose of our investments in the event we disagree with the actions of a portfolio company and may therefore suffer a decrease in the value of our investments. Defaults by our portfolio companies will harm our operating results. A portfolio company’s failure to satisfy financial or operating covenants imposed by us or other lenders could lead to defaults and, potentially, termination of its loans and foreclosure on its assets. This could trigger cross-defaults under other agreements and jeopardize such portfolio company’s ability to meet its obligations under the debt or equity securities that we hold. We may incur expenses to the extent necessary to seek recovery upon default or to negotiate new terms, which may include the waiver of certain financial covenants, with a defaulting portfolio company. Our portfolio companies may incur debt that ranks equally with, or senior to, our investments in such companies. We have invested a substantial portion of our capital in senior secured, unitranche, second lien and subordinated loans issued by our portfolio companies. The portfolio companies may be permitted to incur other debt that ranks equally with, or senior to, the debt securities in which we invest. By their terms, such debt instruments may provide that the holders are entitled to receive payment of interest or principal on or before the dates on which we are
Risk Related To Securities And Investment In Common Stock [Member]
General Description of Registrant [Abstract]
Risk [Text Block]									Risks Related to Our Securities and an Investment in our Common Stock There is a risk that stockholders may not receive distributions or that our distributions may not grow over time and a portion of our distributions may be a return of capital. We have made distributions on a quarterly basis to our stockholders out of assets legally available for distribution. We cannot assure stockholders that we will achieve investment results that will allow us to make a specified level of cash distributions or year-to-year increases in cash distributions. Our ability to pay distributions might be adversely affected by the impact of one or more of the risk factors described in this Annual Report on Form 10-K. Due to the asset coverage test applicable to us under the 1940 Act as a BDC, we may be limited in our ability to make distributions. When we make distributions, we will be required to determine the extent to which such distributions are paid out of current or accumulated taxable (or tax-basis) earnings and profits. Distributions in excess of current and accumulated earnings and profits will be treated as a non-taxable return of capital to the extent of an investor’s basis in our stock and, assuming that an investor holds our stock as a capital asset, thereafter as a capital gain. A return of capital is a return to stockholders of a portion of their original investment in us rather than income or capital gains. The market price of our common stock may fluctuate and decrease significantly. As with any stock, the market price of our common stock will fluctuate with market conditions and other factors. Our common stock is intended for long-term investors and should not be treated as a trading vehicle. Shares of BDCs frequently trade at a discount from their NAV. The market price and liquidity in the market for shares of our common stock may be significantly affected by numerous factors, some of which are beyond our control and may not be directly related to our operating performance. These factors include: • significant volatility in the market price and trading volume of securities of BDCs or other companies in our sector, which is not necessarily related to the operating performance of these companies; • exclusion of our common stock from certain market indices, such as the Russell 2000 Financial Services Index, which could reduce the ability of certain investment funds to own our common stock and put short-term selling pressure on our common stock; • changes in regulatory policies or tax guidelines, particularly with respect to RICs or BDCs; • loss of RIC or BDC status; • our origination activity, including the pace of, and competition for, new investment opportunities; • our ability to incur additional leverage pursuant to Section 61(a)(2) of the 1940 Act and the impact of such leverage on our net investment income and results of operations; • changes, or perceived changes, in earnings or variations in operating results; • changes, or perceived changes, in the value of our portfolio of investments, including upon the sale or disposition of any such investments; • changes in accounting guidelines governing the valuation of our investments; • any shortfall in revenue or net income or any increase in losses from levels expected by investors or securities analysts; • the inability to secure additional debt or equity capital; • potential future sales of common stock or debt securities convertible into or exchangeable or exercisable for our common stock or the conversion of such securities; • departure of OFS Advisor’s, OFSC’s or any of their affiliates’ key personnel; • operating performance of companies comparable to us; • general economic trends and other external factors; and/or • loss of a major funding source. Sales of substantial amounts of our common stock in the public market may have an adverse effect on the market price of our common stock. The shares of our common stock beneficially owned by our principal stockholders, including OFSAM Holdings, are generally available for resale, subject to the provisions of Rule 144 promulgated under the Securities Act unless registered for sale under the Securities Act. OFSAM Holdings is entitled to the benefits of a registration rights agreement granting OFSAM Holdings the right to require us to register its shares for resale. Sales of substantial amounts of our common stock, or the availability of such common stock for sale, could adversely affect the prevailing market prices for our common stock. If this occurs and continues, it could impair our ability to raise additional capital through the sale of securities should we desire to do so. Certain provisions of the Delaware General Corporation Law and our Certificate of Incorporation and Bylaws could deter takeover attempts and have an adverse impact on the price of our common stock. The Delaware General Corporation Law, our Certificate of Incorporation and our Bylaws contain provisions that may have the effect of discouraging a third party from making an acquisition proposal for us. We have also adopted measures that may make it difficult for a third party to obtain control of us, including provisions of our Certificate of Incorporation dividing our Board into three classes with the term of one class expiring at each annual meeting of stockholders. These anti-takeover provisions may inhibit a change in control in circumstances that could give the holders of our common stock the opportunity to realize a premium over the market price of our common stock. Our common stock may trade below its NAV per share, which limits our ability to raise additional equity capital. If our common stock is trading below its NAV per share, we will generally not be able to issue additional shares of our common stock at its market price without first obtaining the approval for such issuance from our stockholders and our independent directors. Shares of BDCs, including shares of our common stock, have historically traded at discounts to their NAVs. As of December 31, 2023, our NAV per share was $12.09 and the closing price of our common shares on the Nasdaq Global Select Market was $11.70. If our common stock trades below NAV, the higher the cost of equity capital may result in it being unattractive to raise new equity, which may limit our ability to grow. The risk of trading below NAV is separate and distinct from the risk that our NAV per share may decline. We cannot predict whether shares of our common stock will trade above, at or below our NAV. If we issue preferred stock, debt securities or convertible debt securities, the NAV of our common stock may become more volatile. We cannot assure the holders of our common stock that the issuance of preferred stock and/or debt securities would result in a higher yield or return to the holders of our common stock. The issuance of preferred stock, debt securities or convertible debt would likely cause the NAV of our common stock to become more volatile. If the dividend rate on the preferred stock, or the interest rate on the debt securities, were to approach the net rate of return on our investment portfolio, the benefit of leverage to the holders of our common stock would be reduced. If the dividend rate on the preferred stock, or the interest rate on the debt securities, were to exceed the net rate of return on our portfolio, the use of leverage would result in a lower rate of return to the holders of common stock than if we had not issued the preferred stock or debt securities. Any decline in the NAV of our investment would be borne entirely by the holders of our common stock. Therefore, if the market value of our portfolio were to decline, the leverage would result in a greater decrease in NAV to the holders of our common stock than if we were not leveraged through the issuance of preferred stock. There is also a risk that, in the event of a sharp decline in the value of our net assets, we would be in danger of: (i) failing to maintain the required asset coverage ratios which may be required by the preferred stock, debt securities, convertible debt or units; (ii) a downgrade in the ratings of the preferred stock, debt securities, convertible debt or units; or (iii) our current investment income not being sufficient to meet the dividend requirements on the preferred stock or the interest payments on the debt securities. If we do not maintain our required asset coverage ratios, we may not be permitted to declare dividends. In order to counteract such an event, we might need to liquidate investments in order to fund redemption of some or all of the preferred stock, debt securities or convertible debt. In addition, we would pay (and the holders of our common stock would bear) all costs and expenses relating to the issuance and ongoing maintenance of the preferred stock, debt securities, convertible debt or any combination of these securities. Holders of preferred stock, debt securities or convertible debt may have different interests than holders of common stock and may, at times, have disproportionate influence over our affairs. Holders of any preferred stock that we may issue will have the right to elect members of our Board and have class voting rights on certain matters. The 1940 Act requires that holders of shares of preferred stock must be entitled as a class to elect two directors at all times and to elect a majority of the directors if dividends on such preferred stock are in arrears by two years or more, until such arrearage is eliminated. In addition, certain matters under the 1940 Act require the separate vote of the holders of any issued and outstanding preferred stock, including changes in fundamental investment restrictions and conversion to open-end status and, accordingly, preferred stockholders could veto any such changes. Restrictions imposed on the declarations and payment of dividends or other distributions to the holders of our common stock and preferred stock, both by the 1940 Act and by requirements imposed by rating agencies, might impair our ability to maintain our tax treatment as a RIC for U.S. federal income tax purposes. Our Unsecured Notes are effectively subordinated to any secured indebtedness we have currently incurred or may incur in the future and will rank pari passu with, or equal to, all outstanding and future unsecured, unsubordinated indebtedness issued by us and our general liabilities. Our Unsecured Notes are not secured by any of our assets or any of the assets of any of our subsidiaries. As a result, the Unsecured Notes are effectively subordinated to any secured indebtedness we or our subsidiaries have outstanding (including the Banc of California Credit Facility and the BNP Facility) or that we or our subsidiaries may incur in the future (or any indebtedness that is initially unsecured and to which we subsequently grant a security interest) to the extent of the value of the assets securing such indebtedness. In any liquidation, dissolution, bankruptcy or other similar proceeding, the holders of any of our secured indebtedness or secured indebtedness of our subsidiaries may assert rights against the assets pledged to secure that indebtedness in order to receive full payment of their indebtedness before the assets may be used to pay other creditors, including the holders of the Unsecured Notes. The Unsecured Notes are structurally subordinated to the indebtedness and other liabilities of our subsidiaries. The Unsecured Notes are obligations exclusively of the Company, and not of any of our subsidiaries. None of our subsidiaries are a guarantor of the Unsecured Notes, and the Unsecured Notes will not be required to be guaranteed by any subsidiary we may acquire or create in the future. Any assets of our subsidiaries will not be directly available to satisfy the claims of our creditors, including holders of the Unsecured Notes. Except to the extent we are a creditor with recognized claims against our subsidiaries, all claims of creditors of our subsidiaries will have priority over our equity interests in such entities (and therefore the claims of our creditors, including holders of the Unsecured Notes) with respect to the assets of such entities. Even if we are recognized as a creditor of one or more of these entities, our claims would still be effectively subordinated to any security interests in the assets of any such entity and to any indebtedness or other liabilities of any such entity senior to our claims. Consequently, the Unsecured Notes will be structurally subordinated to all indebtedness and other liabilities, including trade payables, of any of our existing or future subsidiaries, including SBIC I LP and OFSCC-FS. Certain of these entities currently serve as guarantors under the Banc of California Credit Facility or the BNP Facility, and in the future our subsidiaries may incur substantial additional indebtedness, all of which is and would be structurally senior to the Unsecured Notes. The indenture under which the Unsecured Notes were issued contains limited protection for holders of the Unsecured Notes. The indenture under which the Unsecured Notes were issued offers limited protection to holders of the Unsecured Notes. The terms of the indenture and the Unsecured Notes do not restrict our or any of our subsidiaries’ ability to engage in, or otherwise be a party to, a variety of corporate transactions, circumstances or events that could have a material adverse impact on your investment in the Unsecured Notes. In particular, the terms of the indenture and the Unsecured Notes will not place any restrictions on our or our subsidiaries’ ability to: • issue securities or otherwise incur additional indebtedness or other obligations, including: (i) any indebtedness or other obligations that would be equal in right of payment to the Unsecured Notes; (ii) any indebtedness or other obligations that would be secured and therefore rank effectively senior in right of payment to the Unsecured Notes to the extent of the values of the assets securing such debt; (iii) our indebtedness that is guaranteed by one or more of our subsidiaries and which therefore is structurally senior to the Unsecured Notes; and (iv) securities, indebtedness or obligations issued or incurred by our subsidiaries that would be senior to our equity interests in those entities and therefore rank structurally senior to the Unsecured Notes with respect to the assets of our subsidiaries, in each case other than an incurrence of indebtedness or other obligation that would cause a violation of Section 18(a)(1)(A), as modified by the provisions of Section 61(a), of the 1940 Act as may be applicable to us from time to time, or any successor provisions, whether or not we continue to be subject to such provisions of the 1940 Act, but giving effect, in each case, to any exemptive relief granted to us by the SEC. Currently, these provisions generally prohibit us from making additional borrowings, including through the issuance of additional debt or the sale of additional debt securities, unless our asset coverage, as defined in the 1940 Act, equals at least 200% (now 150%, effective since May 3, 2019) after such borrowings. See “ Item 1A. Risk Factors—Risks Related to our Business and Structure—Because we received the approval of our Board, we became subject to 150% asset coverage effective May 3, 2019 ”; • pay dividends on, or purchase or redeem or make any payments in respect of, capital stock or other securities ranking junior in right of payment to the Unsecured Notes, including subordinated indebtedness, in each case, other than dividends, purchases, redemptions or payments that would cause our asset coverage to fall below the threshold specified in Section 18(a)(1)(B), as modified by the provisions of Section 61(a), of the 1940 Act as may be applicable to us from time to time, or any successor provisions, giving effect to (i) any exemptive relief granted to us by the SEC and (ii) any no-action relief granted by the SEC to another BDC (or to us if we determine to seek such similar no-action or other relief) permitting the BDC to declare any cash dividend or distribution notwithstanding the prohibition contained in Section 18(a)(1)(B), as modified by the provisions of Section 61(a), of the 1940 Act as may be applicable to us from time to time in order to maintain the BDC’s status as a RIC under Subchapter M of the Code. These provisions generally prohibit us from declaring any cash dividend or distribution upon any class of our capital stock, or purchasing any such capital stock if our asset coverage, as defined in the 1940 Act, is below 200% (now 150%, effective since May 3, 2019) at the time of the declaration of the dividend or distribution or the purchase and after deducting the amount of such dividend, distribution or purchase. See “ Item 1A. Risk Factors—Risks Related to our Business and Structure—Because we received the approval of our Board, we became subject to 150% asset coverage effective May 3, 2019 ”; • sell assets (other than certain limited restrictions on our ability to consolidate, merge or sell all or substantially all of our assets); • enter into transactions with affiliates; • create liens (including liens on the shares of our subsidiaries) or enter into sale and leaseback transactions; • make investments; or • create restrictions on the payment of dividends or other amounts to us from our subsidiaries. In addition, the indenture does not require us to make an offer to purchase the Unsecured Notes in connection with a change of control or any other event. Furthermore, the terms of the indenture and the Unsecured Notes do not protect holders of the Unsecured Notes in the event that we experience changes (including significant adverse changes) in our financial condition, results of operations or credit ratings, if any, as they do not require that we or our subsidiaries adhere to any financial tests or ratios or specified levels of net worth, revenues, income, cash flow, or liquidity. Our ability to recapitalize, incur additional debt (including additional debt that matures prior to the maturity of the Unsecured Notes), and take a number of other actions that are not limited by the terms of the Unsecured Notes may have important consequences for holders of the Unsecured Notes, including making it more difficult for us to satisfy our obligations with respect to the Unsecured Notes or negatively affecting the trading value of the Unsecured Notes. Other debt we issue or incur in the future could contain more protections for its holders than the indenture and the Unsecured Notes, including additional covenants and events of default. The issuance or incurrence of any such debt with incremental protections could affect the market for, trading levels, and prices of the Unsecured Notes. We may choose to redeem the Unsecured Notes when prevailing interest rates are relatively low.
General Risk Factors [Member]
General Description of Registrant [Abstract]
Risk [Text Block]									General Risk Factors We may experience fluctuations in our quarterly operating results. We could experience fluctuations in our quarterly operating results due to a number of factors, including the interest rate payable on the debt securities we acquire, the default rate on such securities, the level of our expenses, variations in and the timing of the recognition of realized and unrealized gains or losses, variations in the timing and recognition of any non-recurring fee or dividend income, distributions from portfolio companies, the degree to which we encounter competition in our markets and general economic conditions. In light of these factors, results for any period should not be relied upon as being indicative of performance in future periods. We incur significant costs as a result of being a publicly traded company. As a publicly traded company, we incur legal, accounting and other expenses, including costs associated with the periodic reporting requirements applicable to a company whose securities are registered under the Exchange Act, as well as additional corporate governance requirements, including requirements under the Sarbanes-Oxley Act and other rules implemented by the SEC. We are subject to risks related to corporate social responsibility. Our business faces increasing public scrutiny related to environmental, social and governance (“ESG”) activities, which are increasingly considered to contribute to the long-term sustainability of a company’s performance. A variety of organizations measure the performance of companies on ESG topics, and the results of these assessments are widely publicized. In addition, investments in funds that specialize in companies that perform well in such assessments are increasingly popular, and major institutional investors have publicly emphasized the importance of such ESG measures to their investment decisions. We risk damage to our brand and reputation if we fail to act (or are perceived to not act) responsibly in a number of areas, such as diversity, equity and inclusion, environmental stewardship, corporate governance, support for local communities and transparency and considering ESG factors in our investment processes. Adverse incidents with respect to ESG activities could impact the value of our brand, the cost of our operations and our relationships with investors, all of which could adversely affect our business and results of operations. At the same time, there are various approaches to responsible investing activities and divergent views on the consideration of ESG topics. These differing views increase the risk that any action or lack thereof with respect to any ESG activities will be perceived negatively. “Anti-ESG” sentiment has gained momentum across the U.S., with several states having enacted or proposed “anti-ESG” policies and legislation or issued related legal opinions. If investors subject to such legislation view any of our ESG activities as being in contradiction of such “anti-ESG” policies, legislation or legal opinions, such investors may not invest in us and it could negatively affect the price of our common stock. Regulatory initiatives related to ESG, and the scope and timing of these initiatives, could also adversely affect our business. The SEC has proposed rules to require disclosure of certain ESG-related matters, which may be adopted in 2024. At this time, there is uncertainty regarding the scope of such proposals or when they would become effective (if at all). Compliance with any new laws or regulations increases our regulatory burden and could make compliance more difficult and expensive, affect the manner in which we or our investments conduct business and adversely affect our profitability. Cybersecurity risks and cyber incidents may adversely affect our business or the business of our portfolio companies by causing a disruption to our operations or the operations of our portfolio companies, a compromise or corruption of our confidential information or the confidential information of our portfolio companies and/or damage to our business relationships or the business relationships of our portfolio companies, all of which could negatively impact the business, financial condition and operating results of us or our portfolio companies. A cybersecurity incident is considered to be any adverse event that threatens the confidentiality, integrity or availability of the information resources of us or our portfolio companies. These incidents may be an intentional attack or an unintentional event and could involve gaining unauthorized access to our information systems or those of our portfolio companies or third-party vendors for purposes of misappropriating assets, stealing confidential information, corrupting data or causing operational disruption. The risk of a security breach or disruption, particularly through cyber-attacks or cyber intrusions, including by computer hackers, nation-state affiliated actors, and cyber terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased. Despite careful security and controls design, our information technology systems and the information technology systems of our portfolio companies and our third-party vendors, may be subject to security breaches and cyber-attacks, the result of which may include disrupted operations, misstated or unreliable financial data, liability for stolen assets or information, increased cybersecurity protection and insurance costs, litigation damage to business relationships and damage to our competitiveness, stock price, and long-term stockholder value. The costs related to cyber or other security threats or disruptions may not be fully insured or indemnified by other means. As our, our portfolio companies’ and our third-party vendors’ reliance on technology has increased, so have the risks posed to our information systems, both internally and those provided by OFS Services and third-party service providers, and the information systems of our portfolio companies. OFS Advisor has implemented processes, procedures and internal controls to help mitigate cybersecurity risks and cyber intrusions, but these measures, as well as our increased awareness of the nature and extent of a risk of a cyber incident, do not guarantee that a cyber incident will not occur and/or that our financial results, operations or confidential information will not be negatively impacted by such an incident. In addition, cybersecurity has become a top priority for regulators around the world, including the SEC, and some jurisdictions have enacted laws requiring companies to notify individuals of data security breaches involving certain types of personal data. Even the most well-protected information, networks, systems and facilities remain potentially vulnerable because the techniques used in such attempted security breaches evolve and generally are not recognized until launched against a target, and in some cases, are designed not be detected and, in fact, may not be detected. Accordingly, we and our service providers may be unable to anticipate these techniques or to implement adequate security barriers or other preventative measures, and thus it is impossible for us and our service providers to entirely mitigate this risk. Cybersecurity risks require continuous and increasing attention and other resources from us to, among other actions, identify and quantify these risks and upgrade and expand our technologies, systems and processes to adequately address such risks. Such attention diverts time and other resources from other activities and there is no assurance that our efforts will be effective. If we fail to comply with relevant laws and regulations, we could suffer financial losses, a disruption of our businesses, liability to investors, regulatory intervention or reputational damage. Further, the increased use of mobile and cloud technologies due to the proliferation of remote work resulting from new flexible work arrangements have heightened our and our portfolio companies’ vulnerability to a cybersecurity risk or incident. Reliance on mobile or cloud technology or any failure by mobile technology and cloud service providers to adequately safeguard systems could disrupt our operations, the operations of a portfolio company or the operations of our or their service providers and result in misappropriation, corruption or loss of personal, confidential or proprietary information or the inability to conduct business operations. Extended periods of remote working, whether by us, our portfolio companies, or our service providers, could strain technology resources, introduce operational risks and otherwise heighten the risks described above. Increased data protection regulation may result in increased complexities and risk in connection with the operation of our business. We operate in businesses that are highly dependent on information systems and technology. The costs related to cyber or other security threats or disruptions may not be fully insured or indemnified by other means. Cybersecurity has become a priority for regulators in the U.S. and around the world. Many jurisdictions in which we or our portfolio companies may operate have laws and regulations relating to data privacy, cybersecurity and protection of personal information, and many of these laws and regulations can be inconsistent across jurisdictions and are subject to evolving and, at times, conflicting interpretations. Government officials and regulators, privacy advocates and class action attorneys are increasingly scrutinizing how companies collect, process, use, store, share and transmit personal data. This scrutiny can result in new and shifting interpretations of existing laws, thereby further impacting our business. For example, the General Data Protection Regulation in the European Economic Area and the United Kingdom continues to be interpreted by European and UK courts in novel ways, leading to shifting requirements, country specific differences in application and uncertain enforcement priorities. More recently, new and emerging state laws in the United States on privacy, data and related technologies, such as the California Consumer Privacy Act and the California Privacy Rights Act, as well as industry self-regulatory codes and regulatory requirements, create new privacy and security compliance obligations and expand the scope of potential liability, either jointly or severally with our customers and suppliers. As a security example, pursuant to the SEC’s Rules on Cybersecurity Risk Management, Strategy, Governance, and Incident Disclosure, we are required to make certain disclosures related to material cybersecurity incidents and the reasonably likely impact of such an incident on Form 8-K and will be required to make certain other cybersecurity disclosures, including in this Annual Report on Form 10-K. Determining whether a cybersecurity incident is notifiable or reportable may not be straightforward and any such mandatory disclosures could be costly and lead to negative publicity, loss of customer confidence in the effectiveness of our security measures, diversion of management’s attention and governmental investigations. Non-compliance with any of the aforementioned laws, rules or regulations or other similar laws, rules and regulations, represents a serious risk to our business. Some jurisdictions have also enacted laws requiring companies to notify individuals of data security breaches involving certain types of personal data. Breaches in security could potentially jeopardize our, our employees’ or our investors’ or counterparties’ confidential and other information processed and stored in, and transmitted through, our computer systems and networks, or otherwise cause interruptions or malfunctions in our, our employees’, our investors’, our counterparties’ or third parties’ operations, which could result in significant losses, increased costs, disruption of our business, liability to our investors and other counterparties, regulatory intervention or reputational damage. Furthermore, if we fail to comply with the relevant laws and regulations, it could result in regulatory investigations and penalties. We are subject to risks associated with artificial intelligence and machine learning technology. Recent technological advances in artificial intelligence and machine learning technology (“Machine Learning Technology”) pose risks to us, OFS Advisor and any third parties that we engage with. We could be exposed to the risks of Machine Learning Technology if third-party service providers or any counterparties use Machine Learning Technology in their business activities. We and OFS Advisor are not in a position to control the use of Machine Learning Technology in third-party products or services. Use of Machine Learning Technology could include the input of confidential information in contravention of applicable policies, contractual or other obligations or restrictions, resulting in such confidential information becoming partly accessible by other third-party Machine Learning Technology applications and users. Machine Learning Technology and its applications continue to develop rapidly, and we cannot predict the risks that may arise from such developments. Machine Learning Technology is generally highly reliant on the collection and analysis of large amounts of data, and it is not possible or practicable to incorporate all relevant data into the model that Machine Learning Technology utilizes to operate. Certain data in such models will inevitably contain a degree of inaccuracy and error and could otherwise be inadequate or flawed, which would be likely to degrade the effectiveness of Machine Learning Technology. To the extent we are exposed to the risks of Machine Learning Technology use, any such inaccuracies or errors could adversely impact us and our business. We are subject to risks in using custodians, counterparties, administrators and other agents. We depend on the services of custodians, counterparties, administrators and other agents to carry out certain transactions and other administrative services, including compliance with regulatory requirements in U.S. and non-U.S. jurisdictions. We are subject to risks of errors and mistakes made by these third parties, which may be attributed to us and subject us or our stockholders to reputational damage, penalties or losses. We depend on third parties to provide primary and backup communications and information systems. Any failure or interruption of those systems, including as a result of the termination of an agreement with any third-party service providers, could cause delays or other problems in our activities. Our financial, accounting, data processing, portfolio monitoring, backup or other operating systems and facilities may fail to operate properly or become disabled or damaged as a result of a number of factors including events that are wholly or partially beyond our control. The terms of the contracts with third-party service providers are often customized and complex, and many of these arrangements occur in markets or relate to products that are not subject to regulatory oversight. Accordingly, we may be unsuccessful in seeking reimbursement or indemnification from these third-party service providers. In addition, we rely on a select number of third-party service providers and replacement of any one of our service providers could be difficult and result in disruption and expense. Increased geopolitical unrest, terrorist attacks, acts of war, global health emergencies or natural disasters may impact the businesses in which we invest and harm our business, operating results and financial condition. Terrorist activity and the continued threat of terrorism and acts of civil or international hostility, acts of war, global health emergencies or natural disasters as well as government responses to these types of threats, may disrupt our operations, as well as the operations of the businesses in which we invest. Such acts have created, and continue to create, economic and political uncertainties and have contributed to global economic instability. Future terrorist activities, acts of war, global health emergencies or natural disasters could further affect the domestic and global economies and create additional uncertainties, which may negatively impact the businesses in which we invest directly or indirectly and, in turn, could have a material adverse impact on our business, operating results and financial condition. Losses from terrorist attacks, global health emergencies and natural disasters are generally uninsurable. Further downgrades of the U.S. credit rating, impending automatic spending cuts or a government shutdown could negatively impact our liquidity, financial condition and earnings. U.S. debt ceiling and budget deficit concerns have increased the possibility of additional credit-rating downgrades and economic slowdowns, or a recession in the United States. Although U.S. lawmakers have passed legislation to raise the federal debt ceiling on multiple occasions, ratings agencies have previously lowered, or threatened to lower, the long-term sovereign credit rating on the United States. The impact of this or any further downgrades to the U.S. government’s sovereign credit rating or its perceived creditworthiness could adversely affect the U.S. and global financial markets and economic conditions. Absent quantitative easing by the Federal Reserve, these developments could cause interest rates and borrowing costs to rise, which may negatively impact our ability to access the debt markets on favorable terms. In addition, disagreement over the federal budget has caused the U.S. federal government to shut down for periods of time and may lead to additional U.S. federal government shutdowns. Continued adverse political and economic conditions could have a material adverse effect on our business, financial condition and results of operations.

Accounting Policies [Abstract]
Basis of presentation	Basis of presentation: The Company prepares its consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”), including ASC Topic 946, Financial Services-Investment Companies , and the reporting requirements for Form 10-K, the 1940 Act, and Articles 6 and 12 of Regulation S-X. The consolidated financial statements include all adjustments, consisting only of normal and recurring accruals and adjustments, necessary for fair presentation in accordance with GAAP.
Reclassifications	Reclassifications : Certain prior period amounts may have been reclassified to conform to the current period presentation in the consolidated financial statements and the accompanying notes thereto. Reclassifications did not impact net increase (decrease) in net assets resulting from operations, total assets, total liabilities or total net assets, or consolidated statements of changes in net assets and consolidated statements of cash flows classifications.
Principles of consolidation	Principles of consolidation:
Fair value of financial instruments	Fair value of financial instruments: The Company applies fair value accounting to all of its financial instruments in accordance with ASC Topic 820, Fair Value Measurements (“ASC Topic 820”), which defines fair value, establishes a framework to measure fair value, and requires disclosures regarding fair value measurements. Fair value is defined as the price to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is determined through the use of models and other valuation techniques, valuation inputs, and assumptions market participants would use to value the financial instrument. Highest priority is given to prices for identical financial instruments quoted in active markets (Level 1) and the lowest priority is given to unobservable valuation inputs (Level 3). The availability of observable inputs can vary significantly and is affected by many factors, including the type of product, whether the product is new to the market, whether the product is traded on an active exchange or in the secondary market, and the current market conditions. To the extent that the valuation is based on unobservable inputs, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for financial instruments classified as Level 3 (i.e., those instruments valued using unobservable inputs), which comprise the majority of the Company’s investments. See Note 5 for details.
Investment classification	Investment classification:
Significant Subsidiaries	Significant Subsidiaries : The Company evaluates the issuers of its Control Investments for significance in accordance with Rules 3-09 and 4-08(g) of Regulation S-X. No issuers of Control Investments were considered a significant subsidiary under these rules as of or for the years ended December 31, 2023, 2022 and 2021.
Use of estimates	Use of estimates:
Reportable segments	Reportable segments: The Company has a single reportable segment and single operating segment structure.
Cash	Cash:
Revenue recognition	Revenue recognition: Interest income : Interest income from the Company’s loan and CLO debt investments is recognized on an accrual basis and reported as an interest receivable until collected. Interest income is accrued based on the outstanding principal amount on the consolidated schedule of investments and the contractual terms of the debt investment. Certain of the Company’s investments contain a payment-in-kind interest income provision (“PIK interest”). The PIK interest, computed at the contractual rate specified in the applicable investment agreement, is added to the principal balance of the investment, rather than being paid in cash. PIK interest on such investments is generally due at the maturity of the investment. Recognition of cash and PIK interest includes assessments of collectability. The Company discontinues the accrual of interest income, including PIK interest, when there is reasonable doubt that the interest income will be collected. See Non-Accrual Loans section. Loan origination fees, original issue discount (“OID”), market discount or premium, and loan amendment fees (collectively, “Net Loan Fees”) are recorded as an adjustment to the amortized cost of the investment, and accreted or amortized as an adjustment to interest income over the life of the respective debt investment using a method that approximates the effective interest method. When the Company receives a loan principal payment, the unamortized Net Loan Fees related to the paid principal is accelerated and recognized in interest income. The Company may also acquire or receive equity, warrants or other equity-related securities in connection with the Company’s acquisition of, subsequent amendment or restructuring to, debt investments. The Company determines the cost basis of the equity investment based on its relative fair value to the fair value of debt investments and other securities or consideration received. Any resulting difference between the face amount of the debt and its recorded cost resulting from the assignment of value to the equity investment is treated as OID, and accreted into interest income as described above. Interest income - Structured Finance Securities : Structured Finance Securities include CLO mezzanine debt, CLO subordinated notes and loan accumulation facility positions. Interest income from investments in CLO subordinated securities is recognized on the basis of the estimated effective yield to expected redemption utilizing estimated cash flows in accordance with ASC Subtopic 325-40, Beneficial Interests in Securitized Financial Assets . The Company monitors the expected cash flows from its CLO subordinated notes, and the accretable yields are generally established at purchase, and reevaluated upon the receipt of the initial distribution and each subsequent quarter thereafter. Expected cash flows inherent in the Company’s estimates of accretable yields are based on expectations of defaults and loss-on-default severity, as well as other loan-performance assumptions, impacting the loans in the underlying CLO portfolios. These estimated cash flows are subject to a reasonable possibility of near-term change due to economic and credit market conditions, and the effect of these changes could be material. Interest income from investments in loan accumulation facilities is recognized on an accrual basis based on an estimated yield. Income notes associated with loan accumulation facilities generally pay returns equal to the actual income earned on facility assets less costs of senior financing and manager costs. Interest income is generally received upon the earlier of the closing of the CLO securitization or liquidation of the underlying portfolio. The Company periodically evaluates the realizability of such amounts and, if necessary, subsequently adjusts the estimated yield. Dividend income : Dividend income on common equity securities in limited liability companies, partnerships, and other private entities, generally payable in cash, is accrued at the time dividends are declared (in the absence of a formal ex-dividend or record date). Declared dividends payable in cash are reported as dividends receivable until collected. Distributions in excess of current or accumulated net income of the underlying portfolio company are recorded as return of capital and, correspondingly, as a reduction in the cost of the investment. Dividend income on preferred equity investments is accrued based on the contractual terms of the preferred equity investment, subject to assessments of collectability (including fair value coverage). Dividends on preferred equity securities may be payable in cash or in additional preferred securities. Non-cash dividends payable in additional preferred securities (“PIK dividends”) are recorded as an adjustment (i.e., increase) to the cost basis of the investment. The Company discontinues accrual of PIK dividends when there is reasonable doubt that the income will ultimately be collected. Fee income : The Company generates fee revenue in the form of syndication, prepayment, and other contractual fees, that are recognized as the related services are rendered. In the general course of its business, the Company receives certain fees, such as management fees, from portfolio companies which are non-recurring in nature. Prepayment fees are received on certain loans when repaid prior to their scheduled due date, which are recognized as earned when received. Syndication fees are received for capital structuring, loan syndication or advisory services from certain portfolio companies, which are recognized as earned upon closing of the investment. The Company also earns unfunded commitment fees on undrawn revolving lines of credit and delayed draw facility commitments. Investment transactions and net realized and unrealized gains and losses on investments : Investment transactions are reported on a trade-date basis. Unsettled trades as of the statement of assets and liabilities date are included in receivable for investments sold and payable for investments purchased, as applicable. Realized gains or losses on investments are measured by the difference between the net proceeds from the disposition and the amortized cost basis of the investment on the trade date. Investments are valued at fair value in accordance with ASC 820 as determined in good faith by OFS Advisor, as the valuation designee, under the oversight of the Board. The Company reports changes in the fair value of investments, relative to the amortized cost of investments, as net unrealized appreciation (depreciation) on investments in the consolidated statements of operations. Non-accrual loans
Income taxes	Income taxes: The Company has elected to be treated, and intends to qualify annually, as a RIC under Subchapter M of the Code. To qualify as a RIC, the Company must, among other things, meet certain source of income and asset diversification requirements, and timely distribute at least 90% of its investment company taxable income (“ICTI”) annually to its stockholders. The Company has made, and intends to continue to make, requisite distributions to its stockholders, which generally relieves the Company from U.S. federal income taxes. Depending on the level of ICTI earned in a tax year, the Company may choose to retain ICTI in an amount less than that which would trigger U.S. federal income tax liability under Subchapter M of the Code. However, the Company would be liable for a 4% excise tax on such undistributed income. Such spillover income increases the Company’s RIC distribution requirement in the following year. An excise tax liability is recognized when the Company determines its estimated current year annual ICTI, capital gain net income, and any undistributed ICTI and capital gain net income from the prior year, as defined in the Code, exceeds distributions paid during the calendar year. For the years ended December 31, 2023, 2022 and 2021, the Company accrued U.S. federal excise taxes of $0, $100 and $0, respectively. The Company may utilize OFSCC-MB when making equity investments in portfolio companies taxed as pass-through entities to meet its source-of-income requirements as a RIC. For U.S. federal income tax purposes, OFSCC-MB is not consolidated with the RIC and is taxed as a C-Corporation. See Note 8 for further information. The Company evaluates tax positions taken in the course of preparing its tax returns to determine whether they are “more-likely-than-not” to be sustained by the applicable tax authority. Tax benefits of positions not deemed to meet the more-likely-than-not threshold could result in greater and undistributed ICTI, income and excise tax expense, and, if involving multiple years, a re-assessment of the Company’s RIC status. GAAP requires recognition of accrued interest and penalties related to uncertain tax benefits as income tax expense. There were no uncertain income tax positions at December 31, 2023, 2022 and 2021. The current and prior three tax years remain subject to examination by U.S. federal and most state tax authorities.
Distributions	Distributions: Distributions to common stockholders are recognized on the record date. The timing of distributions as well as the amount to be paid out as a distribution is determined by the Board each quarter. Distributions from net investment income and net realized gains are determined in accordance with the Code. Net realized capital gains, if any, are distributed at least annually, although the Company may decide to retain such capital gains for investment. Distributions paid in excess of current and accumulated ICTI and not capital gains are considered returns of capital to stockholders. The Company has adopted a dividend reinvestment plan (“DRIP”) that provides for reinvestment of any distributions the Company declares in cash on behalf of its stockholders, unless a stockholder elects to receive cash. As a result, if the Board authorizes and the Company declares a cash distribution, then stockholders who have not “opted out” of the DRIP will have their cash distribution automatically reinvested in additional shares of the Company’s common stock, rather than receiving the cash distribution.
Deferred debt issuance costs	Deferred debt issuance costs: Deferred debt issuance costs represent fees and other direct incremental costs incurred in connection with the Company’s borrowings. Deferred debt issuance costs are presented as a direct reduction of the related debt liability on the consolidated statements of assets and liabilities, except for deferred debt issuance costs associated with the Company’s revolving line of credit arrangements, which are included in prepaid expenses and other assets on the consolidated statements of assets and liabilities. Unamortized deferred debt issuance costs included in prepaid expenses and other assets on the consolidated statements of assets and liabilities as of December 31, 2023 and 2022, were $1,062 and $1,316, respectively. Deferred debt issuance costs are amortized to interest expense over the term or expected term of the related debt.
Intangible asset	Intangible asset: On December 4, 2013, in connection with the SBIC Acquisition, the Company recorded an intangible asset of $2,500 attributable to the SBIC license. The Company amortizes the intangible asset on a straight-line basis over its estimated useful life. During the first quarter of 2022, the Company changed its estimate of the useful life to terminate on March 1, 2024, due to early redemptions of SBA debentures. The Company recognized amortization of $408, $409 and $222 for the years ended December 31, 2023, 2022, and 2021, respectively. The Company tests its intangible asset for impairment if events or circumstances suggest that the asset carrying value may not be fully recoverable. The carrying value of the intangible asset, net of accumulated amortization, was $69 and $477 at December 31, 2023 and 2022, respectively, is included in prepaid expenses and other assets in the consolidated statements of assets and liabilities.
Interest expense	Interest expense:
Concentration of credit risk	Concentration of credit risk: Aside from the Company’s investments, financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash deposits at financial institutions. At various times during the year, the Company exceeds the federally insured limits. The Company places cash deposits only with high credit quality institutions which OFS Advisor believes will mitigate the risk of loss due to credit risk. If borrowers completely fail to perform according to the terms of the contracts, the amount of loss due to credit risk from the Company’s investments is equal to the Company’s recorded investment and the unfunded commitments disclosed in Note 6 .
New Accounting Pronouncements and Rule Issuances	New Accounting Pronouncements and Rule Issuances In June 2022, the FASB issued Fair Value Measurement (Topic 820), Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions (“ASU 2022-03”). ASU 2022-03 clarifies guidance for fair value measurement of an equity security subject to a contractual sale restriction and establishes new disclosure requirements for such equity securities. ASU 2022-03 is effective for fiscal years beginning after December 15, 2023 and for interim periods within those fiscal years, with early adoption permitted. The Company has concluded that this guidance will not have a material impact on its consolidated financial statements. In December 2023, the FASB issued Income Taxes (Topic 740), Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 amend Topic 740 to, among other things, require on an annual basis, the disclosure of additional income tax information related to the Company’s effective tax rate reconciliation and income taxes paid. ASU 2023-09 is intended to enhance the transparency by providing more detailed income tax disclosures that would be useful in making capital allocation decisions. ASU 2023-09 amendments are effective for annual periods beginning after December 15, 2024. The Company is currently evaluating the impact, if any, ASU 2023-09 will have on its consolidated financial statements.

The Capital Gains Fee payable to the Advisor under the Investment Advisory Agreement does not include net unrealized appreciation, and accordingly no amount was payable or due to the Advisor as of December 31, 2021. During the year ended December 31, 2022, the Company reversed the previously accrued Capital Gains Fees of $1,916 due to a reduction in net unrealized appreciation on the investment portfolio.
