Summary of Significant Accounti

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, 2022, 2021 and 2020. 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 may be in excess of the FDIC insurance limits. The Company does not believe its cash balances are exposed to any significant credit risk. Cash includes aggregate amounts totaling $14,937 and $43,048 held in US Bank N.A. and Citibank N.A. money market deposit accounts as of December 31, 2022 and 2021, respectively. In addition, the Company’s use of cash held by SBIC I LP and OFSCC-FS is limited by SBA regulation and the terms and conditions of the BNP Facility, respectively, including but not limited to, 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. Recognition of PIK interest includes assessments of collectability. The Company discontinues 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. Further, the Company may 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 fair value, and 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 debt, CLO subordinated securities 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 assumed cash flows in accordance with ASC Sub-topic 325-40, Beneficial Interests in Securitized Financial Assets . The Company monitors the expected cash flows from its CLO subordinated securities, and the accretable yields are determined and updated periodically. 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. 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. 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, and 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. Investment transactions and net realized and unrealized gain or loss 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. 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. Investments are valued at fair value as determined in good faith by OFS Advisor, as the valuation designee, under the oversight of the Board. After recording all appropriate interest, dividend, and other income, some of which is recorded as an adjustment to the cost basis of the investment as described above, the Company reports changes in the fair value of investments as net unrealized appreciation (depreciation) on investments in the consolidated statements of operations. Non-accrual loans : Management reviews all loans that become past due on principal and interest, and/or when there is reasonable doubt that principal or interest will be collected, for placement on non-accrual status. When a loan is placed on non-accrual status, accrued and unpaid interest is reversed. Additionally, Net Loan Fees are no longer accreted to interest income 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 principal 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, the investments are estimated to be fully collectible as to all principal and interest. See Note 4 for further information on loans on non-accrual status as of December 31, 2022 and December 31, 2021. 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”) 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 income. Excise tax liability is recognized when the Company determines its estimated current year annual ICTI, as defined in the Code, exceeds distributions from current year ICTI. For the years ended December 31, 2022, 2021 and 2020, the Company accrued U.S. federal excise taxes of $100, $0 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, 2022, 2021 and 2020. 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 ICTI and not capital gains are considered returns of capital to stockholders. The Company has adopted a distribution 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 line of credit arrangements, which are included in prepaid expenses and other assets on the consolidated statements of assets and liabilities. Unamortized debt issuance costs included in prepaid expenses and other assets on the consolidated statements of assets and liabilities as of December 31, 2022 and 2021, were $1,316 and $671, respectively. Deferred debt issuance costs are amortized to interest expense over the term of the related debt. Goodwill: On December 4, 2013, in connection with the Company's acquisition of the remaining ownership interests in SBIC I LP and SBIC I GP, LLC, making SBIC I LP a wholly owned subsidiary of the Company (“SBIC Acquisition”), the Company recorded goodwill of $1,077. The decline in the price of the Company’s common stock and the level at which it continued to trade relative to the broader stock indices for the BDC industry, led management to conclude in the third quarter of 2020 that an impairment in the value of the Company’s goodwill was more likely than not. Moreover, due to the discount at which the Company’s stock traded to its net asset value, management concluded that the impairment of goodwill equal to the full amount of its carrying value of $1,077 was appropriate. 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 this 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 continued early redemptions of SBA debentures. The Company recognized amortization of $409, $222 and $206 for the years ended December 31, 2022, 2021 and 2020, 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 $477 and $886 at December 31, 2022 and 2021, respectively, is included in prepaid expenses and other assets in the consolidated statements of assets and liabilities. Interest expense: Interest expense is recognized on an accrual basis as incurred. 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 may exceed 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. The amount of loss due to credit risk from its investments, if borrowers completely fail to perform according to the terms of the contracts, is equal to the Company's recorded investment and the unfunded commitments disclosed in Note 6 . New Accounting Pronouncements and Rule Issuances In March 2020, the FASB issued “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ” (“ASU 2020-04”) to provide optional guidance to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. ASU 2020-04 established Topic 848 to provide relief during the temporary transition period and includes a sunset provision based on expectations of when the London Interbank Offered Rate (“LIBOR”) would cease being published. ASU 2022-06 further defers the sunset provision date of Topic 848 from December 31, 2022, to December 31, 2024, after which entities will no longer be permitted to apply the relief in Topic 848. Upon adoption of ASU 2022-06, there was no significant impact to the Company’s consolidated financial position. In December 2020, the SEC issued a final rule adopting Rule 2a-5 under the 1940 Act to establish requirements for determining fair value in good faith for purposes of the 1940 Act. Pursuant to Rule 2a-5, on September 7, 2022, 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. In order for the Board to maintain oversight, OFS Advisor implemented the required reporting elements as prescribed in Rule 2a-5. 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 amended Topic 820 to, among other things, (i) clarify the guidance when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of an equity security, (ii) amend a related illustrative example and (iii) introduce new disclosure requirements for equity securities subject to contractual sale restrictions. ASU 2022-03 amendments are effective for the Company’s fiscal year ending December 31, 2024, and interim periods within the year. ASU 2022-03 provisions are to be applied prospectively with any adjustments made to earnings on the date of adoption. The Company is currently evaluating the impact, if any, ASU 2022-03 will have on its consolidated financial position or disclosures.

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, 2022. 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. OFS Advisor has elected to exclude the value of the intangible assets resulting from the SBIC Acquisition from the base management fee calculation. Effective from January 1, 2020 through December 31, 2022, OFS Advisor agreed to reduce the base management fee attributable to all assets held through OFSCC-FS (“OFSCC-FS Assets”), excluding cash. The agreement reduced the base management fee to 0.25% per quarter (1.00% annualized) of the average value of the OFSCC-FS Assets (excluding cash) 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. This agreement was renewed for the 2023 calendar year on January 11, 2023. 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% (which is 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 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). As of December 31, 2022 and December 31, 2021, the payable to investment adviser and affiliates on the consolidated statements of assets and liabilities includes a Capital Gains Fee of $0 and $1,916, respectively. During the year ended December 31, 2022, the Company reversed the previously accrued Capital Gains Fees due to a reduction in net unrealized appreciation on the investment portfolio. On May 4, 2020, OFS Advisor agreed to irrevocably waive the receipt of $441 in Income Incentive Fees (based on net investment income) related to net investment income, that it would otherwise be entitled to receive under the Investment Advisory Agreement for the three months ended March 31, 2020. As a result of the voluntary fee waiver, the Company incurred Income Incentive Fee expense of $442 for the three months ended March 31, 2020, which is equal to half the Income Incentive Fee expense the Company would have incurred for the three months ended March 31, 2020. The voluntary fee waiver did not include a Capital Gains Fee, which was $0 for the three months ended March 31, 2020. 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, 2022. 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, 2022, affiliates of OFS Advisor held 3,019,694 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, 2022, 2021 and 2020 are presented below: December 31, 2022 2021 2020 Base management fees $ 7,979 $ 7,669 $ 7,605 Incentive fees: Income Incentive Fee 2,276 2,352 2,025 Income Incentive Fee waiver — — (441) Capital Gains Fee (1) (1,916) 1,916 — Administration fees 1,742 1,758 1,855 Distributions paid to affiliates 3,503 2,764 2,553 (1) As of December 31, 2021, the Capital Gains Fee of $1,916 was deferred, and not due to the Advisor, until the close of the year in which such gains are realized. 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 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 a documented valuation policy that is applied in a consistent manner. On September 7, 2022, pursuant to 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. In order for the Board to maintain oversight, OFS Advisor implemented the requirements 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 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 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. If the asset or liability has a specified term, a Level 2 input must be observable for substantially the full term of the asset or liability. Level 2 inputs include: (i) quoted prices for similar assets or liabilities in active markets; (ii) quoted prices for identical or similar assets or liabilities in markets that are not active; (iii) inputs other than quoted prices that are observable for the asset or liability; and (iv) inputs that are derived principally from or corroborated by observable market data. 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 significant management 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 loans for the years ended December 31, 2022 and 2021, respectively: Year Ended December 31, 2022 2021 Transfers from Level 2 to Level 3 $ 3,218 $ — Transfers from Level 3 to Level 2 — — 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 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 generally up to three months after the transaction date. Senior secured debt investments with a fair value of $0 and $72,572, respectively, were valued at their Transaction Price at December 31, 2022 and December 31, 2021. 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 of the CLO vehicle, including compliance with collateralization tests, concentration limits and restructuring activity, if applicable. The fair value of the Company’s equity investments as well as certain of its non-performing debt investments are 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 multiple analyses 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”). EBITDA 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 recurring monthly revenue or a delineated measure of portfolio company EBITDA. 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. The Company’s investments are subject to market risk as a result of economic and political developments, including impacts from rising interest rates and inflation rates, the ongoing war between Russia and Ukraine, the continuing COVID-19 pandemic, and the risk of recession 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 following tables present the Company's investment portfolio measured at fair value on a recurring basis as of December 31, 2022 and 2021, respectively.

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 EBITDA 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 EBITDA 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 EBITDA 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.

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 are non-recourse to the Company, have interest payable semi-annually and a ten-year maturity. The interest rate is fixed at the time of SBA pooling, which is March and September of each year, at a market-driven spread over U.S. Treasury Notes with ten-year maturities. The Company received exemptive relief from the SEC effective November 26, 2013, which permits the Company 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, 2022, SBIC I LP redeemed $19,000 of SBA debentures that were contractually due March 1, 2025 and September 1, 2025. The Company recognized losses on extinguishment of debt of $144 related to the acceleration of unamortized deferred borrowing costs on the redeemed debentures. As of December 31, 2022 and 2021, SBIC I LP had outstanding SBA debentures of $50,920 and $69,920, respectively. On a stand-alone basis, SBIC I LP held $176,521 and $195,502 in assets at December 31, 2022 and 2021, respectively, which accounted for approximately 34% and 34% of the Company’s total consolidated assets, respectively. These assets cannot be pledged under any non-SBA debt obligation of the Company. The following table shows the Company’s outstanding SBA debentures payable as of December 31, 2022 and 2021: Fixed Interest Rate SBA debentures outstanding Pooling Date Maturity Date December 31, 2022 December 31, 2021 March 25, 2015 March 1, 2025 2.872 % $ 50,920 $ 65,920 September 23, 2015 September 1, 2025 3.184 — 4,000 SBA debentures outstanding 50,920 69,920 Unamortized debt issuance costs (223) (555) SBA debentures outstanding, net of unamortized debt issuance costs $ 50,697 $ 69,365 For the years ended December 31, 2022, 2021 and 2020, the components of interest expense, cash paid for interest, effective interest rates and average outstanding balances for the SBA debentures were as follows: Years Ended December 31, 2022 2021 2020 Stated interest expense $ 1,552 $ 2,627 $ 4,070 Amortization of debt issuance costs 188 209 332 Total interest and debt financing costs $ 1,740 $ 2,836 $ 4,402 Cash paid for interest expense $ 1,739 $ 2,978 $ 4,830 Effective interest rate 3.22 % 3.27 % 3.31 % Average outstanding balance $ 53,991 $ 86,710 $ 132,803 Unsecured Notes: The unsecured notes totaled $180,000 and $180,000 in aggregate principal debt at December 31, 2022 and 2021, respectively.

The Unsecured Notes Due February 2026, the Unsecured Notes Due October 2028, the Unsecured Notes Due April 2025, the Unsecured Notes Due October 2025, the Unsecured Notes Due September 2023 and Unsecured Notes Due October 2026, combined (the “Unsecured Notes”), of which the Unsecured Notes Due February 2026 and the Unsecured Notes Due October 2028 were outstanding at December 31, 2021, are direct unsecured obligations and rank equal in right of payment with all current and future unsecured indebtedness of the Company. Because the 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 PWB Credit Facility and BNP Facility. The indenture governing the 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, 2022, 2021 and 2020, the components of interest expense, cash paid for interest, effective interest rates and average outstanding balances for the Unsecured Notes were as follows: Years Ended December 31, 2022 2021 2020 Stated interest expense $ 8,663 $ 11,160 $ 10,044 Amortization of debt issuance costs 1,029 1,403 909 Total interest and debt financing costs $ 9,692 $ 12,563 $ 10,953 Cash paid for interest expense $ 8,683 $ 10,384 $ 9,645 Effective interest rate 5.38 % 6.03 % 6.84 % Average outstanding balance $ 180,000 $ 208,240 $ 160,022 As of December 31, 2022, the 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 $ 2,452 4.75 % 5.39 % 2/10/2026 Unsecured Notes Due October 2028 55,000 1,195 4.95 % 5.32 % 10/31/2028 Total $ 180,000 $ 3,647 (1) The weighted-average fixed cash interest rate on the Unsecured Notes as of December 31, 2022 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, at its option on or after October 31, 2023. PWB Credit Facility : The Company is party to a business loan agreement (“BLA”) with Pacific Western Bank, as lender, to provide the Company with a $25,000 senior secured revolving credit facility. The PWB Credit Facility is available for general corporate purposes including investment funding and is scheduled to mature on February 28, 2024. The maximum availability of the PWB Credit Facility is equal to 50% of the aggregate outstanding principal amount of eligible loans included in the borrowing base, which excludes subordinated loan investments and as otherwise specified in the BLA. The PWB Credit Facility is guaranteed by OFSCC-MB and secured by all of our current and future assets excluding assets held by SBIC I LP, OFSCC-FS, and the Company’s partnership interests in SBIC I LP and SBIC I GP. The PWB Credit Facility bears interest at a variable rate of the Prime Rate plus a 0.25% margin, with a 4.00% floor, and includes an unused commitment fee for any unused portion in excess of $15,000, payable monthly in arrears, equal to 0.50% per annum on any unused portion. As of December 31, 2022, the stated interest rate of the PWB Credit Facility was 7.75%.

BNP Facility: OFSCC-FS is party to the BNP Facility, which provides for borrowings in an aggregate principal amount up to $150,000, of which $104,700 was drawn as of December 31, 2022. Borrowings under the BNP Facility bear interest of SOFR plus an applicable spread, which is determined on the basis of industry-recognized portfolio company metrics at the time of funding. The BNP Facility will mature on the earlier of June 20, 2027 or upon certain other events defined in the credit agreement which result in accelerated maturity. Borrowings under the BNP Facility are secured by substantially all of the assets held by OFSCC-FS, which were $173,692 and 185,105, or 33% and 33% of the Company's total consolidated assets at December 31, 2022 and 2021, respectively. On June 24, 2022, OFSCC-FS amended the BNP Facility to, among other things: (i) extend the reinvestment period under the BNP Facility for three years from June 20, 2022 to June 20, 2025; (ii) extend the maturity date under the BNP Facility from June 20, 2024 to June 20, 2027; (iii) convert the benchmark interest rate from LIBOR to SOFR; (iv) increase the applicable margin by 0.40% on all classes of loans; and (v) increase the applicable margin floor from 1.925% to 2.65%.

Federal Income Tax

Federal Income Tax	12 Months Ended
	Dec. 31, 2022
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, 2022, the Company met the source of income and asset diversification requirements, and intends to continue to meet these requirements. As of December 31, 2022, the Company recognized excise tax of $100 related to estimated undistributed income for the year ended December 31, 2022. 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: Years Ended December 31, 2022 (1) 2021 2020 Ordinary taxable income $ 15,564 $ 12,207 $ 11,516 Long-term capital gain — — — Return of capital — — — Total distributions to stockholders $ 15,564 $ 12,207 $ 11,516 (1) The calculation of 2022 U.S. federal taxable income is based on certain estimated amounts, including information received from third parties and, as a result, actual 2022 U.S. federal taxable income will not be finally determined until the Company’s 2022 U.S. federal tax return is filed in 2023 (and, therefore, such estimate is subject to change). Tax-basis components of distributable earnings (accumulated losses) as of December 31, 2022 and 2021, were as follows: December 31, 2022 2021 Ordinary income (RIC) $ 3,551 $ 1,193 Undistributed earnings and profits (net operating loss carry-forward) (OFSCC-MB; C-Corporation) 2,606 3,325 Capital loss carryforwards: RIC – short-term, non-expiring (3,683) (3,226) RIC – long-term, non-expiring (34,335) (34,292) 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 $101, $2,142 and $331 for the years ended December 31, 2022, 2021 and 2020, respectively. 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, 2022 and 2021, were as follows: December 31, 2022 2021 Tax-basis amortized cost of investments $ 473,716 $ 452,722 Tax-basis gross unrealized appreciation on investments 92,230 83,033 Tax-basis gross unrealized depreciation on investments (65,370) (28,656) Tax-basis net unrealized appreciation (depreciation) on investments 26,860 54,377 Fair value of investments $ 500,576 $ 507,099 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, 2022 and 2021, were as follows: 2022 2021 Total net unrealized appreciation (depreciation) on investments held by RIC entities $ 27,494 $ 54,282 OFSCC-MB (C-Corp): Gross unrealized appreciation on investments 144 649 Gross unrealized depreciation on investments (778) (554) Total net unrealized appreciation (depreciation) on investments on investments held by OFSCC-MB (634) 95 Total tax-basis net unrealized appreciation on investments $ 26,860 $ 54,377 Deferred tax assets and liabilities as of December 31, 2022 and 2021, were as follows: December 31, 2022 2021 Total deferred tax assets $ 205 $ 141 Valuation allowance on deferred tax assets (124) — Total deferred tax liabilities (81) (167) 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 distributions to stockholders on a quarterly basis of substantially all of its net investment income. In addition, although the Company intends to make distributions of any net realized capital gains, out of assets legally available for such distributions at least annually, the Company may in the future decide to retain such net investment income and capital gains for investment or corporate purposes. The Company may be limited in its ability to make distributions due to the BDC asset coverage requirements of the 1940 Act. The Company’s ability to make distributions may also be affected by its restrictions imposed by the SBA regulations on the Company’s wholly owned SBIC subsidiary, and may require the prior approval of the SBA. In addition, distributions from OFSCC-FS to the Company are restricted by the terms and conditions of the BNP Facility. At December 31, 2022 and December 31, 2021, net assets of SBIC I LP were $125,236 and $125,375, respectively, which included cash of $8,587 and $11,265, of which $4,180 and $12,422 were available for distribution at December 31, 2022 and 2021, respectively. At December 31, 2022 and December 31, 2021, net assets of OFSCC-FS were $68,214 and $76,072, respectively, which included cash of $3,706 and $3,693, of which $0 and $0 were available for distribution to the Company at December 31, 2022 and 2021, respectively.

Distributions in excess of the Company’s current and accumulated ICTI would be treated first as a return of capital to the extent of a stockholder’s tax basis, and any remaining distributions would be treated as a capital gain. The determination of the tax attributes of the Company’s distributions is made annually as of the end of its fiscal year based upon its estimated ICTI and distributions paid for the full year. Each year, if required, a statement on Form 1099-DIV identifying the source of the distribution is mailed to the Company’s stockholders. Stock repurchase program: The Company is authorized to acquire up to $10,000 of its outstanding common stock through May 22, 2024 (the “Stock Repurchase Program”). Under the Stock Repurchase Program, the Company may repurchase shares in open-market transactions, including through block purchases, depending on prevailing market conditions and other factors.

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) (9) : Base management fees payable under the Investment Advisory Agreement 5.22 % (3) Incentive fees payable under the Investment Advisory Agreement 1.26 % (4) Interest payments on borrowed funds 9.44 % (5) Other expenses 2.79 % (6) Total annual expenses 18.71 % Base management fee reduction (0.80) % (8) Total annual expenses, net of fee reduction 17.91 % (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. (2) The expenses of the dividend reinvestment plan 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, 2022 before the effect of the base management fee reduction on certain assets and assumes net of assets of $180.4 million and leverage of $335.6 million, which reflects our net assets and leverage as of December 31, 2022. 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 5.22% presented in the table above does not reflect the (0.80)% 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, 2022, 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 assumed 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, 2022. Based on our outstanding indebtedness as of December 31, 2022, our estimated annualized cost of funds, which includes all interest and amortization of debt issuance costs is 5.70%. As of December 31, 2022, our asset coverage ratio was 163% (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. We do not expect to issue any preferred stock during the next twelve months and, therefore, have not included the cost of issuing and servicing preferred stock in the table. As of December 31, 2022, availability under the PWB Credit Facility and BNP Facility was $25.0 million and $45.3 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, 2022. “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 will be 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 18.08%. (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. (9) Estimated. 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 $152 $400 $588 $883 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) $161 $420 $611 $898 While the examples assume reinvestment of all distributions at NAV, participants in our dividend reinvestment plan 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.

(6) “Other Expenses” referenced in the table above are based on actual amounts incurred for the year ended December 31, 2022. “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 will be 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 18.08%. (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. (9) Estimated. 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 $152 $400 $588 $883 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) $161 $420 $611 $898 While the examples assume reinvestment of all distributions at NAV, participants in our dividend reinvestment plan 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.

Purpose of Fee Table , Note [Text Block]									The following table is intended to assist you in understanding the costs and expenses that you will bear directly or indirectly. We caution you that the percentages indicated in the table below are estimates and may vary. Except where the context suggests otherwise, whenever this Annual Report on Form 10-K contains a reference to fees or expenses paid by “us,” “the Company” or “OFS Capital,” or that “we” will pay fees or expenses, you will indirectly bear such fees or expenses as an investor in OFS Capital.

Management Fee not based on Net Assets, Note [Text Block]									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, 2022 before the effect of the base management fee reduction on certain assets and assumes net of assets of $180.4 million and leverage of $335.6 million, which reflects our net assets and leverage as of December 31, 2022. 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 5.22% presented in the table above does not reflect the (0.80)% 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, 2022, 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 assumed 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, warrants and other equity securities 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. 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 more than 20 years in 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]									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 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. • 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. • 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. • If we make subordinated investments, the obligors or the portfolio companies may not generate sufficient cash flow to service their debt obligations to us. • The interest rates of our investments might be subject to change, including as a result of the transition away from LIBOR and the adoption of alternative reference rates, which could affect our results of operations. We are subject to risks relating 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 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 and political tensions in the United States and around the world, 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, the impacts of economic sanctions as a result of the ongoing war between Russia and Ukraine, rising interest rates and a period 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. Russia’s military invasion of Ukraine in February 2022 and the resulting global responses, including economic sanctions by the United States, the European Union and other countries, could increase volatility and uncertainty in the financial markets and adversely affect regional and global economies. The extent and duration of the ongoing war in Ukraine and the repercussions of such war are impossible to predict, but could result in significant market disruptions. Depending on direction and timing, the Russian-Ukraine war may result in adverse changes to, among other things: (i) general economic and market conditions; (ii) shipping and transportation costs and supply chain constraints; (iii) interest rates, currency exchange rates, and expenses associated with currency management transactions; (iv) available credit in certain markets; (v) import and export activity from certain markets; and (vi) laws, regulations, treaties, pacts, accords, and governmental policies. Economic and military sanctions related to the Russian-Ukraine war, or other conflicts, have the potential to gravely impact markets, global supply and demand, energy prices, inflation, import/export policies, and the availability of labor in certain markets. The foregoing could have a material adverse effect on the ability of underlying borrowers and issuers to perform their obligations. We expect the current high inflationary environment to 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, 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 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 several years ago. 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 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 2022 until as late as December 31, 2023. 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 the continuing COVID-19 pandemic and other disruptions in the economy, including impacts of interest rates and high inflation rates, we anticipate that 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 as discussed below under the risk factor “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, 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 under the 1940 Act, 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. 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 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 are subject to additional regulations due to SBIC I LP’s status as a Small Business Investment Company. Our current investment strategy includes SBIC I LP, which is regulated by the SBA. The SBA regulations require that a licensed SBIC be periodically examined and audited by the SBA to determine its compliance with the relevant SBA regulations. If SBIC I LP fails to comply with applicable SBA regulations, the SBA could, depending on the severity of the violation, limit or prohibit its use of debentures, declare outstanding debentures immediately due and payable, and/or limit its ability to make new investments. The SBA, as a creditor, will have a superior claim to SBIC I LP’s assets over SBIC I LP’s limited partners and our stockholders in the event SBIC I LP is liquidated or the SBA exercises its remedies under the SBA debentures issued by SBIC I LP in the event of a default. In addition, the SBA can revoke or suspend a license for willful or repeated violation of, or willful or repeated failure to observe, any provision of the Small Business Investment Act of 1958 or any rule or regulation promulgated thereunder. These actions by the SBA would, in turn, negatively affect us because of our ownership interest in SBIC I LP. The SBA places certain limitations on the financing terms of investments by SBICs in portfolio companies and prohibits an SBIC from providing funds to small businesses for certain purposes, such as relending, real estate or investing in companies outside of the United States, and providing funds to businesses engaged in a few prohibited industries and to certain “passive” (i.e., non-operating) companies. In addition, without prior SBA approval, an SBIC may not invest an amount equal to more than approximately 30% of the SBIC’s regulatory capital in any one company and its affiliates. SBIC I LP is subject to ongoing regulation and oversight by the SBA, including requirements with respect to maintaining certain minimum financial ratios and other covenants. In addition, SBIC I LP may also be limited in its ability to make distributions to us if it does not have sufficient accumulated net profit, in accordance with SBA regulations. These requirements may make it more difficult for us to achieve our investment objectives. 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 SBIC I LP and OFSCC-FS, and our ownership interest in SB

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 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. • 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. • 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. • If we make subordinated investments, the obligors or the portfolio companies may not generate sufficient cash flow to service their debt obligations to us. • The interest rates of our investments might be subject to change, including as a result of the transition away from LIBOR and the adoption of alternative reference rates, which could affect our results of operations. We are subject to risks relating 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 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 the Covid-19 Pandemic [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 and political tensions in the United States and around the world, 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, the impacts of economic sanctions as a result of the ongoing war between Russia and Ukraine, rising interest rates and a period 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. Russia’s military invasion of Ukraine in February 2022 and the resulting global responses, including economic sanctions by the United States, the European Union and other countries, could increase volatility and uncertainty in the financial markets and adversely affect regional and global economies. The extent and duration of the ongoing war in Ukraine and the repercussions of such war are impossible to predict, but could result in significant market disruptions. Depending on direction and timing, the Russian-Ukraine war may result in adverse changes to, among other things: (i) general economic and market conditions; (ii) shipping and transportation costs and supply chain constraints; (iii) interest rates, currency exchange rates, and expenses associated with currency management transactions; (iv) available credit in certain markets; (v) import and export activity from certain markets; and (vi) laws, regulations, treaties, pacts, accords, and governmental policies. Economic and military sanctions related to the Russian-Ukraine war, or other conflicts, have the potential to gravely impact markets, global supply and demand, energy prices, inflation, import/export policies, and the availability of labor in certain markets. The foregoing could have a material adverse effect on the ability of underlying borrowers and issuers to perform their obligations. We expect the current high inflationary environment to 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, 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 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 several years ago. 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 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 2022 until as late as December 31, 2023. 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 the continuing COVID-19 pandemic and other disruptions in the economy, including impacts of interest rates and high inflation rates, we anticipate that 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 as discussed below under the risk factor “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.”
Risk Related To Business And Structure [Member]
General Description of Registrant [Abstract]
Risk [Text Block]									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, 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 under the 1940 Act, 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. 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 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 are subject to additional regulations due to SBIC I LP’s status as a Small Business Investment Company. Our current investment strategy includes SBIC I LP, which is regulated by the SBA. The SBA regulations require that a licensed SBIC be periodically examined and audited by the SBA to determine its compliance with the relevant SBA regulations. If SBIC I LP fails to comply with applicable SBA regulations, the SBA could, depending on the severity of the violation, limit or prohibit its use of debentures, declare outstanding debentures immediately due and payable, and/or limit its ability to make new investments. The SBA, as a creditor, will have a superior claim to SBIC I LP’s assets over SBIC I LP’s limited partners and our stockholders in the event SBIC I LP is liquidated or the SBA exercises its remedies under the SBA debentures issued by SBIC I LP in the event of a default. In addition, the SBA can revoke or suspend a license for willful or repeated violation of, or willful or repeated failure to observe, any provision of the Small Business Investment Act of 1958 or any rule or regulation promulgated thereunder. These actions by the SBA would, in turn, negatively affect us because of our ownership interest in SBIC I LP. The SBA places certain limitations on the financing terms of investments by SBICs in portfolio companies and prohibits an SBIC from providing funds to small businesses for certain purposes, such as relending, real estate or investing in companies outside of the United States, and providing funds to businesses engaged in a few prohibited industries and to certain “passive” (i.e., non-operating) companies. In addition, without prior SBA approval, an SBIC may not invest an amount equal to more than approximately 30% of the SBIC’s regulatory capital in any one company and its affiliates. SBIC I LP is subject to ongoing regulation and oversight by the SBA, including requirements with respect to maintaining certain minimum financial ratios and other covenants. In addition, SBIC I LP may also be limited in its ability to make distributions to us if it does not have sufficient accumulated net profit, in accordance with SBA regulations. These requirements may make it more difficult for us to achieve our investment objectives. 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 SBIC I LP and OFSCC-FS, and our ownership interest in SBIC I LP and SBIC I GP, 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 management fee payable to OFS Advisor is payable based on our total assets (other than cash and cash equivalents and intangible assets related to the SBIC Acquisition but including assets purchased with borrowed amounts and including assets owned by any consolidated entity), OFS Advisor has a financial incentive 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 management fee payable to OFS Advisor. 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; 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, 2022, our asset coverage ratio was 163%, 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) (38.4)% (24.5)% (10.6)% 3.3% 17.1% ( 1 ) Assumes $500.6 million in investments at fair value, $335.6 million in outstanding debt, $180.4 million in net assets, and an average cost of funds of 5.70% as of December 31, 2022. Our investment portfolio must experience an annual return of 3.8% at least to cover interest payments on the outstanding debt. This example is for illustrative purposes only, and actual interest rates on 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 flow 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. 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 our 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 “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 rising 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. Under a reverse repurchase agreement, we will effectively pledge our assets as collateral to secure a short-term loan. Generally, the other party to the agreement makes the loan in an amount equal to a percentage of the fair value of the pledged collateral. At the maturity of the reverse repurchase agreement, we will be required to repay the loan and correspondingly receive back our collateral. While used as collateral, the assets continue to pay principal and interest which are for our benefit. Our use of reverse repurchase agreements, if any, involves many of the same risks involved in our use of leverage, as the proceeds from reverse repurchase agreements generally will be invested in additional securities. There is a risk that the market value of the securities acquired in the reverse repurchase agreement may decline below the price of the securities that we have sold but remain obligated to purchase. In addition, there is a risk that the market value of the securities retained by us may decline. If a buyer of securities under a reverse repurchase agreement were to file for bankruptcy or experience insolvency, we may be adversely affected. Also, in entering into reverse repurchase agreements, we would bear the risk of loss to the extent that the proceeds of such agreements at settlement are less than the fair value of the underlying securities being pledged. In addition, due to the interest costs associated with reverse repurchase agreements transactions, our NAV would decline, and, in some cases, we may be worse off than if we had not used such instruments. Our ability to enter into transactions involving derivatives and financial commitment transactions may be limited. In November 2020, the SEC adopted Rule 18f-4 regarding the ability of a BDC (or a registered investment company) to use derivatives and other transactions that create future payment or delivery obligations. Under the rule, BDCs that use derivatives would be subject to a value-at-risk leverage limit, a derivatives risk management program and testing requirements and requirements related to board reporting. These requirements will apply unless the BDC qualifies as a “limited derivatives user,” as defined in the rule. Under the rule, a BDC may enter into an unfunded commitment agreement that is not a derivatives transaction, such as an agreement to provide financing to a portfolio company, if the BDC has, among other things, a reasonable belief, at the time it enters into such an agreement, that it will have sufficient cash and cash equivalents to meet its obligations with respect to all of its unfunded commitment agreements, in each case as it becomes due. Collectively, these requirements may limit our ability to use derivatives and/or enter into certain other financial contracts. We may in the future determine to fund a portion of our investments with preferred stock, which would magnify the potential for gain or loss and the risks of investing in us in the same way as our borrowings. Preferred stock, which is another form of leverage, has the same risks to our common stockholders as borrowings because the dividends on any preferred stock we issue must be cumulative. Payment of such dividends and repayment of the liquidation preference of such preferred stock must take preference over any dividends or other payments to our common stockholders, and preferred stockholders are not subject to any of our expenses or losses and are not entitled to participate in any income or appreciation in excess of their stated preference. We operate in a highly competitive market for investment opportunities, which could reduce returns and result in losses. A number of entities compete with us to make the types of investments that we plan to make. We compete with public and private funds, other BDCs, commercial and investment banks, commercial finance companies and, to the extent they provide an alternative form of financing, private equity and hedge funds. Many of our competitors are substantially larger and have considerably greater financial, technical and marketing resources than we do. For example, some of our competitors may have access to funding sources that are not available to us. In addition, some of our competitors may have higher risk tolerances or different risk assessments than us. Furthermore, many of our competitors are not subject to the regulatory restrictions that the 1940 Act imposes on us as a BDC or the source of income, asset diversification and distribution requirements we must satisfy to maintain our RIC tax treatment. These characteristics could allow our competitors to consider a wider variety of instruments, establish more relationships and offer better pricing and more flexible structuring than we are able to. The competitive pressures we face may have a material adverse effect on our business, financial condition and results of operations. As a result of this competition, we may not be able to take advantage of attractive investment opportunities from time to time, and we may not be able to identify and make investments that are consistent with our investment objective. With respect to the investments we make, we will not seek to compete based primarily on the interest rates we will offer, and we believe that some of our competitors may make loans with interest rates that will be lower than the rates we offer. In the secondary market for acquiring existing loans, we expect to compete generally on the basis of pricing terms. With respect to all investments, we may lose some investment opportunities if we do not match our competitors’ pricing, terms and structure. However, if we match our competitors’ pricing, terms and structure, we may experience decreased net interest income, lower yields and increased risk of credit loss. We may also compete for investment opportunities with OFSAM Holdings and its other affiliates or accounts managed by OFSAM Holdings or one of its other affiliates. Although OFS Advisor will allocate opportunities in accordance with its policies and procedures, allocations to such other accounts will reduce the amount and frequency of opportunities available to us and may not be in the best interests of us and our stockholders. Moreover, the performance of investments will not be known at the time of allocation. We may suffer credit losses. Investment in middle-market companies is highly speculative and involves a high degree of risk of credit loss, and therefore our securities may not be suitable for someone with a low risk tolerance. These risks are likely to increase during volatile economic periods, such as the recent economic volatility in the United States, Europe and China. 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. We have elected to be treated as a RIC under Subchapter M of the Code, but no assurance can be given that we will be able to maintain tax treatment as a RIC. As a RIC, we are not required to pay U.S. federal income taxes at corporate rates on our income and capital gains distributed (or deemed distributed) to our stockholders, provided that we satisfy certain distribution and other requirements. To continue to qualify for tax treatment as a RIC under the Code and to be relieved of federal taxes on income and gains distributed to our stockholders, we must meet certain source-of-income, asset diversification and distribution requirements. The distribution requirement for a RIC is satisfied if we distribute at least 90% of our net ordinary income and net short-term capital gains in excess of net long-term capital losses, if any, to our stockholders on an annual basis. Because we use debt financing, and may, in the future, issue preferred stock, we are subject to certain asset coverage ratio requirements under the 1940 Act and financial covenants under loan and credit agreements or preferred stock that could, under certain circumstances, restrict us from making distributions necessary to qualify for tax treatment as a RIC. If we are unable to obtain cash from other sources, we may fail to maintain our qualification for the tax benefits available to RICs and, thus, may be subject to U.S. federal income tax at corporate rates. To maintain our qualification for tax treatment as a RIC, we must also meet certain asset diversification requirements at the end of each calendar quarter. Failure to meet these tests may result in our having to dispose of certain investments quickly in order to prevent the loss of RIC status. Because most of our investments are in private or thinly traded public companies, any such dispositions could be made at disadvantageous prices and may result in substantial losses. If we fail to continue to qualify for tax treatment as a RIC for any reason and become subject to U.S. federal income tax at corporate rates, the resulting corporate taxes could substantially reduce our net assets, the amount of income available for distributions to stockholders and the amount of our distributions and the amount of funds available for new investments. Such a failure would have a material adverse effect on us and our stockholders. Our subsidiaries and portfolio companies may be unable to make distributions to us that will enable us to meet RIC requirements, which could result in the imposition of an entity-level tax. In order for us to maintain our tax treatment as a RIC and to minimize corporate-level taxes, we are required to distribute on an annual basis substantially all of our taxable income, which includes income from our subsidiaries and portfolio companies. SBIC I LP may be limited by the SBIC Act and SBA regulations governing SBICs from making certain distributions to us that may be necessary to enable us to continue to qualify as a RIC. Distributions from SBIC I LP currently require the prior approval of the SBA. In additio
Risk Related To Advisor And Affiliates [Member]
General Description of Registrant [Abstract]
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 the 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 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 will determine 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 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—License Agreement.” In addition, we rent office space from a subsidiary of OFSAM and pay to 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 will create 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 advisor (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 us 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, 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 interests 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 and the intangible assets that resulted from the SBIC Acquisition, 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 interests 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 in cash the deferred income that was previously accrued. 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’ respective officers, directors, members, managers, stockholders and employees will not be liable to us, any subsidiary of ours, our directors, our stockholders or any subsidiary’s stockholders or partners 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’ respective officers, directors, members, managers, 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.

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 decline, 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, 2022, we had $335.6 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. We have received an exemptive order from the SEC to permit us to exclude the debt of SBIC I LP guaranteed by the SBA from our definition of senior securities in our statutory asset coverage ratio under the 1940 Act. 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 net asset value 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 net asset value 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 13, 2022, our stockholders approved a proposal that authorizes us to issue shares of our common stock at a price below our current net asset value, 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.

Risk [Text Block]									Risks Related to Our Investments Certain economic and political conditions in Europe including developments relating to the Euro and the withdrawal of the United Kingdom from the European Union may impact the value of our investments and increase the risk profile of our portfolio. Certain of our investments may be affected by developments relating to the Euro. European financial markets have experienced volatility and have been adversely affected by the COVID-19 pandemic, concerns about rising government debt levels, credit rating downgrades, and possible defaults on or restructuring of government debt. These events have caused bond yield spreads (the cost of borrowing debt in the capital markets) and credit default spreads (the cost of purchasing credit protection) to increase, most notably in relation to certain eurozone countries. The governments of several member countries of the European Union have experienced large public budget deficits, which have adversely affected the sovereign debt issued by those countries and may ultimately lead to declines in the value of the Euro. In addition, it is possible that countries that have adopted the Euro could abandon the Euro and return to a national currency and/or that the Euro will cease to exist as a single currency in its current form. The effects on a country of abandonment of the Euro or a country's forced expulsion from the European Union are impossible to predict but are likely to be negative. The exit of any country out of the European Union or the abandonment by any country of the Euro would likely have a destabilizing effect on all eurozone countries and their economies and a negative effect on the global economy as a whole. Furthermore, the United Kingdom withdrew from and ceased to be a member state of the European Union at 11:00 p.m. GMT on January 31, 2020. On December 24, 2020, a trade agreement was concluded between the European Union and the United Kingdom (the "EU-UK Trade and Cooperation Agreement"), which has applied provisionally after the end of the transition period ending on December 31, 2020. The EU-UK Trade and Cooperation Agreement has been ratified by the UK Parliament, the European Parliament and the Council of the European Union and entered into force on May 1, 2021. Accordingly, the EU-UK Trade and Cooperation Agreement now governs the relationship between the European Union and the United Kingdom. However, although the EU-UK Trade and Cooperation Agreement covers many issues such as economic partnership, free trade, law enforcement, judicial co-operation and governance, the EU-UK Trade and Cooperation Agreement is silent on items such as financial services equivalence and data protection adequacy. Our investments and portfolio’s risk profile may be materially affected by political and economic uncertainty relating to the United Kingdom's withdrawal from the European Union, which might also have an adverse impact on our business, financial condition, results of operations and prospects and could therefore also be materially detrimental to our stockholders. Any such potential adverse economic conditions may also affect the ability of the underlying borrowers and issuers to perform their obligations. 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 the 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 often difficult to estimate the extent of, or even to identify, any contingent claims that might be made. In addition, certain claims that have priority by law (for example, claims for taxes) may be substantial. In addition, since our mezzanine 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, to a lesser extent, 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 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 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 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 certain 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 level, 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 sector, and may force our portfolio companies in this industry sector 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 sector 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, amend the documents in order to move collateral, or amend the documents 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. Investment in private and middle-market companies involves 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 a fully informed investment decision, 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 and market conditions, as well as 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 our company is subject to the following specific risks: increased price sensitivity to a deteriorating economic environment; greater risk of loss due to default or declining credit quality; adverse company specific events are more likely to render the issuer unable to make interest and/or principal payments; and if a negative perception of the lower grade debt market develops, the price and liquidity of lower grade securities may be depressed. 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 company and, in turn, on us. Middle-market companies also may 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 the portfolio 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 CLOs, we may be in a first loss or subordinated position with respect to realized losses on the assets of the CLOs in which it is invested. 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. The failure by a CLO in which we invest to satisfy financial covenants, including with respect to adequate collateralization and/or interest coverage tests, could lead to a reduction in the payments we receive from the CLO. In the event that a CLO fails certain tests, holders of CLO senior debt may be entitled to additional payments that would, in turn, reduce the payments we would otherwise be entitled to receive. 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. In addition, if a CLO does not meet the asset coverage tests or the interest coverage test set forth in the indenture governing the Structured Finance Securities issued by the CLO, cash would be diverted from the Structured Finance Securities to first pay the secured notes in amounts sufficient to cause such tests to be satisfied. We will have no influence on 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 decrease in value over time, may be difficult to sell in a timely manner, may be difficult to appraise, and may 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. Without restriction under the financing agreement, the borrower could 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 net asset value 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 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 net asset value 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 net asset value 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 defaults on its obligations under any of its 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. Beyond the asset diversification requirements associated with our qualification as a RIC under the Code, we do not have fixed guidelines for diversification. 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 any specific industries, our investments may be concentrated i
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. Our ability to make distributions may also be affected by our ability to receive distributions from SBIC I LP, which is governed by SBA regulations. When we make distributions, we will be required to determine the extent to which such distributions are paid out of current or accumulated 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 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 of 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, SBICs or BDCs; • loss of RIC or BDC status; • failure of SBIC I LP to maintain its status as an SBIC; • 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 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 • 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 traded at discounts to their NAVs. As of December 31, 2022, our NAV per share was $13.47. The daily average closing price of our shares on the Nasdaq Global Select Market for the year ended December 31, 2022 was $10.74. 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 failing to maintain required asset coverage ratios which may be required by the preferred stock, debt securities, convertible debt or units or of a downgrade in the ratings of the preferred stock, debt securities, convertible debt or units or our current investment income might not be 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 PWB Credit Facility and the BNP Facility) or that we or our subsidiaries may incur in the future (or any indebtedness that is initially unsecured as 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 PWB 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) indebtedness of ours 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 such 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 such 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) 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 such 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, distributions from our subsidiaries and 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, investment 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 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 relationships with investors, all of which could adversely affect our business and results of operations. Additionally, new regulatory initiatives related to ESG could adversely affect our business. The SEC has proposed rules to require disclosure of certain ESG-related matters, which may be adopted in 2023. 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 portfolio companies conduct our businesses 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.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2022
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: 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	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: 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	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, 2022, 2021 and 2020.
Use of estimates	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	Reportable segments: The Company has a single reportable segment and single operating segment structure.
Cash	Cash: The Company’s cash balances are maintained with a member bank of the Federal Deposit Insurance Corporation (“FDIC”) and at times, such balances may be in excess of the FDIC insurance limits. The Company does not believe its cash balances are exposed to any significant credit risk. Cash includes aggregate amounts totaling $14,937 and $43,048 held in US Bank N.A. and Citibank N.A. money market deposit accounts as of December 31, 2022 and 2021, respectively. In addition, the Company’s use of cash held by SBIC I LP and OFSCC-FS is limited by SBA regulation and the terms and conditions of the BNP Facility, respectively, including but not limited to, payment of interest expense and principal on the outstanding borrowings.
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. Recognition of PIK interest includes assessments of collectability. The Company discontinues 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. Further, the Company may 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 fair value, and 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 debt, CLO subordinated securities 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 assumed cash flows in accordance with ASC Sub-topic 325-40, Beneficial Interests in Securitized Financial Assets . The Company monitors the expected cash flows from its CLO subordinated securities, and the accretable yields are determined and updated periodically. 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. 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. 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, and 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. Investment transactions and net realized and unrealized gain or loss 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. 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. Investments are valued at fair value as determined in good faith by OFS Advisor, as the valuation designee, under the oversight of the Board. After recording all appropriate interest, dividend, and other income, some of which is recorded as an adjustment to the cost basis of the investment as described above, the Company reports changes in the fair value of investments as net unrealized appreciation (depreciation) on investments in the consolidated statements of operations.
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”) 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 income. Excise tax liability is recognized when the Company determines its estimated current year annual ICTI, as defined in the Code, exceeds distributions from current year ICTI. For the years ended December 31, 2022, 2021 and 2020, the Company accrued U.S. federal excise taxes of $100, $0 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, 2022, 2021 and 2020. 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 ICTI and not capital gains are considered returns of capital to stockholders. The Company has adopted a distribution 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 line of credit arrangements, which are included in prepaid expenses and other assets on the consolidated statements of assets and liabilities. Unamortized debt issuance costs included in prepaid expenses and other assets on the consolidated statements of assets and liabilities as of December 31, 2022 and 2021, were $1,316 and $671, respectively. Deferred debt issuance costs are amortized to interest expense over the term of the related debt.
Goodwill	Goodwill: On December 4, 2013, in connection with the Company's acquisition of the remaining ownership interests in SBIC I LP and SBIC I GP, LLC, making SBIC I LP a wholly owned subsidiary of the Company (“SBIC Acquisition”), the Company recorded goodwill of $1,077. The decline in the price of the Company’s common stock and the level at which it continued to trade relative to the broader stock indices for the BDC industry, led management to conclude in the third quarter of 2020 that an impairment in the value of the Company’s goodwill was more likely than not. Moreover, due to the discount at which the Company’s stock traded to its net asset value, management concluded that the impairment of goodwill equal to the full amount of its carrying value of $1,077 was appropriate.
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 this 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 continued early redemptions of SBA debentures. The Company recognized amortization of $409, $222 and $206 for the years ended December 31, 2022, 2021 and 2020, 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 $477 and $886 at December 31, 2022 and 2021, respectively, is included in prepaid expenses and other assets in the consolidated statements of
Interest expense	Interest expense: Interest expense is recognized on an accrual basis as incurred.
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 may exceed 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. The amount of loss due to credit risk from its investments, if borrowers completely fail to perform according to the terms of the contracts, 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 March 2020, the FASB issued “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ” (“ASU 2020-04”) to provide optional guidance to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. ASU 2020-04 established Topic 848 to provide relief during the temporary transition period and includes a sunset provision based on expectations of when the London Interbank Offered Rate (“LIBOR”) would cease being published. ASU 2022-06 further defers the sunset provision date of Topic 848 from December 31, 2022, to December 31, 2024, after which entities will no longer be permitted to apply the relief in Topic 848. Upon adoption of ASU 2022-06, there was no significant impact to the Company’s consolidated financial position. In December 2020, the SEC issued a final rule adopting Rule 2a-5 under the 1940 Act to establish requirements for determining fair value in good faith for purposes of the 1940 Act. Pursuant to Rule 2a-5, on September 7, 2022, 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. In order for the Board to maintain oversight, OFS Advisor implemented the required reporting elements as prescribed in Rule 2a-5. 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 amended Topic 820 to, among other things, (i) clarify the guidance when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of an equity security, (ii) amend a related illustrative example and (iii) introduce new disclosure requirements for equity securities subject to contractual sale restrictions. ASU 2022-03 amendments are effective for the Company’s fiscal year ending December 31, 2024, and interim periods within the year. ASU 2022-03 provisions are to be applied prospectively with any adjustments made to earnings on the date of adoption. The Company is currently evaluating the impact, if any, ASU 2022-03 will have on its consolidated financial position or disclosures.
