SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
Mar. 31, 2026
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited consolidated financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). The Company is an investment company for the purposes of accounting and financial reporting in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946, Financial Services—Investment Companies (“ASC 946”). The unaudited consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, the SPV, the 2015-1 Issuer, the CSL III SPV, and the Credit Fund II. All significant intercompany balances and transactions have been eliminated. U.S. GAAP for an investment company requires investments to be recorded at fair value. The carrying value for all other assets and liabilities approximates their fair value. The unaudited consolidated financial statements have been prepared in accordance with U.S. GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Articles 6 and 10 of Regulation S-X. Accordingly, certain disclosures accompanying the annual consolidated financial statements prepared in accordance with U.S. GAAP are omitted. In the opinion of management, all adjustments considered necessary for the fair presentation of unaudited consolidated financial statements for the interim periods presented have been included. These adjustments are of a normal, recurring nature. This Form 10-Q should be read in conjunction with the Company's annual report on Form 10-K for the year ended December 31, 2025. The results of operations for the three months ended March 31, 2026 are not necessarily indicative of the operating results to be expected for the full year. Certain prior period disclosures within the Consolidated Statement of Cash flows have been amended to conform to the current period presentation.
Use of Estimates	Use of Estimates The preparation of unaudited consolidated financial statements in conformity with U.S. GAAP requires management to make assumptions and estimates 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 revenues and expenses during the reporting period. Management’s estimates are based on historical experiences and other factors, including expectations of future events that management believes to be reasonable under the circumstances. It also requires management to exercise judgment in the process of applying the Company’s accounting policies. Assumptions and estimates regarding the valuation of investments and their resulting impact on base management and incentive fees involve a higher degree of judgment and complexity and these assumptions and estimates may be significant to the unaudited consolidated financial statements. Actual results could differ from these estimates and such differences could be material.
Investments	Investments Investment transactions are recorded on the trade date. Realized gains or losses are measured by the difference between the net proceeds from the repayment or sale and the amortized cost basis of the investment at the time of exit using the specific identification method without regard to unrealized appreciation or depreciation previously recognized, and includes investments charged off during the period, net of recoveries. Net change in unrealized appreciation or depreciation on investments as presented in the accompanying Consolidated Statements of Operations reflects the net change in the fair value of investments, including the reversal of previously recorded unrealized appreciation or depreciation when gains or losses are realized. See Note 3, Fair Value Measurements, to these unaudited consolidated financial statements for further information about fair value measurements.
Derivative Instruments	Derivative Instruments The Company follows the guidance in Topic 815, Derivatives and Hedging (“ASC 815”), when accounting for derivative instruments. The Company recognizes all derivative instruments at fair value as either assets or liabilities in its unaudited consolidated financial statements. Derivative instruments are measured in terms of the notional contract amount and derive their value based upon one or more underlying instruments. Derivative instruments are subject to various risks similar to non-derivative instruments including market, credit, liquidity, and operational risks. The Company manages these risks on an aggregate basis as part of its risk management process. The Company has in the past and may in the future use forward currency contracts to economically hedge the currency exposure associated with certain foreign-denominated investments. The use of forward currency contracts does not eliminate fluctuations in the price of the underlying securities the Company owns or intends to acquire but establishes a rate of exchange in advance. Until the contracts are closed, fluctuations in the value of these contracts are measured by the difference in the exchange rates on the contract date and reporting date and are recorded as net change in unrealized gain (loss) on forward currency contracts within the Consolidated Statements of Operations. When the contracts are closed, realized gains (losses) are recorded as realized gain (loss) on forward currency contracts within the Consolidated Statements of Operations. The forward currency contracts are recorded at fair value on the Consolidated Statements of Assets and Liabilities by counterparty on a net basis, not taking into account collateral posted which is recorded separately, if applicable. The change in fair value of the forward currency contracts is reflected as net change in unrealized (gain) loss on forward currency contracts within the Consolidated Statements of Cash Flows. Refer to Note 8, Derivative Instruments, to these unaudited consolidated financial statements for further information. The Company uses interest rate swaps to hedge some of the Company's fixed rate debt. The Company designated the interest rate swaps as the hedging instrument in an effective hedge accounting relationship and therefore the periodic payments and receipts are recognized as components of interest expense and credit facility fees within the accompanying Consolidated Statements of Operations. Depending on the nature of the balance at the end of the period, the fair value of the interest rate swap is either an asset and included in derivative assets, at fair value on the accompanying Consolidated Statements of Assets and Liabilities or a liability and included in derivative liabilities, at fair value on accompanying Consolidated Statements of Assets and Liabilities. The change in fair value of the interest rate swap is offset by a change in the carrying value of the fixed rate debt. The change in fair value of the interest rate swap is reflected as net change in unrealized gain (loss) on interest rate swaps within the Consolidated Statements of Cash Flows. Any amounts held by the Company in a separate account to cover collateral obligations to the counterparty under the terms of the ISDA Master Agreement (as defined in Note 8, Derivative Instruments, to these unaudited consolidated financial statements) and interest rate swap agreements are included in cash, cash equivalents, and restricted cash on the accompanying Consolidated Statements of Assets and Liabilities. Any amounts paid to and held by the counterparty to cover collateral obligations under the terms of the interest rate swap agreement are included in prepaid expenses and other assets on the accompanying Consolidated Statements of Assets and Liabilities. Any amounts paid from the counterparty due to market value fluctuations to cover collateral under the terms of the interest rate swap agreement are included in other accrued expenses and liabilities on accompanying Consolidated Statements of Assets and Liabilities.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash Cash, cash equivalents and restricted cash consist of demand deposits and highly liquid investments (e.g., money market funds, U.S. Treasury notes) with original maturities of three months or less. Cash equivalents are carried at amortized cost, which approximates fair value. The Company’s cash, cash equivalents and restricted cash are held with two large financial institutions and cash held at each financial institution may, at times, exceed the Federal Deposit Insurance Corporation insured limit. As of March 31, 2026 and December 31, 2025, the Company held restricted cash balances of $28,780 and $31,474, respectively. Restricted cash balances represent amounts that are collected and held by trustees appointed by the Company for payment of interest expense and principal on the outstanding borrowings and reinvestment into new assets. Restricted cash balances also include amounts held by the Company in a separate account to cover collateral obligations under the terms of any interest rate swap agreements. The amounts are held by the trustees as custodians of the assets securing certain of the Company’s financing transactions.
Revenue Recognition	Revenue Recognition Interest from Investments Interest income is recorded on an accrual basis and includes the accretion of discounts and amortization of premiums. Discounts from and premiums to par value on debt investments purchased are accreted/amortized into interest income over the life of the respective security using the effective interest method. The amortized cost of debt investments represents the original cost, including origination fees and upfront fees received that are deemed to be an adjustment to yield, adjusted for the accretion of discounts and amortization of premiums, if any. The Company may have loans in its portfolio that contain payment-in-kind (“PIK”) provisions. PIK income represents interest that is accrued and recorded as interest income at the contractual rates, increases the loan principal on the respective capitalization dates, and is generally due at maturity. As of March 31, 2026 and December 31, 2025, the fair value of the loans in the portfolio with PIK provisions was $390,789 and $305,090, respectively, which represents approximately 17.2% and 12.4%, respectively, of total investments at fair value. For the three months ended March 31, 2026 and 2025, the Company earned $6,481 and $5,379 in PIK income, respectively. Dividend Income Dividend income from the investment funds, Credit Fund and Credit Fund II, Structured Credit Partners, and other investments funds, if any, is recorded on the record date for the investment fund to the extent that such amounts are payable by the investment funds and are expected to be collected. Other Income Other income may include income such as consent, waiver, amendment, unused, underwriting, arranger and prepayment fees associated with the Company’s investment activities as well as any fees for managerial assistance services rendered by the Company to the portfolio companies. Such fees are recognized as income when earned or the services are rendered. The Company may receive fees for guaranteeing the outstanding debt of a portfolio company. Such fees are amortized into other income over the life of the guarantee. The unamortized amount, if any, is included in prepaid expenses and other assets in the accompanying Consolidated Statements of Assets and Liabilities. For the three months ended March 31, 2026 and 2025, the Company earned $2,595 and $951, respectively, in other income, primarily from amendment fees, prepayment fees and unused commitment fees. Non-Accrual Income Loans are generally placed on non-accrual status when principal or interest payments are past due or when there is reasonable doubt that principal or interest will be collected in full. Accrued and unpaid interest is generally reversed when a loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment regarding collectability. Non-accrual loans are restored to accrual status when past due principal and interest are current or there is no longer any reasonable doubt that such principal or interest will be collected in full and, in management’s judgment, are likely to remain current. Management may determine not to place a loan on non-accrual status if the loan has sufficient collateral value and is in the process of collection.
Credit Facilities, Senior Notes, and Debt Securitization – Related Costs, Expenses and Deferred Financing Costs	Credit Facilities, Senior Notes, and Debt Securitization – Related Costs, Expenses and Deferred Financing Costs The Credit Facilities, the 2015-1N Debt, and the Senior Notes, each as defined within Note 9, Borrowings, to these unaudited consolidated financial statements, are recorded at carrying value, which approximates fair value. Interest expense and unused commitment fees on the Credit Facilities are recorded on an accrual basis. Unused commitment fees are included in interest expense and credit facility fees in the accompanying Consolidated Statements of Operations. Deferred financing costs include capitalized expenses related to the closing or amendments of the Credit Facilities. Amortization of deferred financing costs for the Credit Facilities is computed on the straight-line basis over the respective term of each Credit Facility. The unamortized balance of such costs is included in prepaid expenses and other assets in the accompanying Consolidated Statements of Assets and Liabilities. The amortization of such costs is included in interest expense and credit facility fees in the accompanying Consolidated Statements of Operations. Debt issuance costs include capitalized expenses including structuring and arrangement fees related to the offering of the 2015-1N Debt and Senior Notes. Amortization of debt issuance costs for the notes is computed on the effective yield method over the term of the notes. The unamortized balance of such costs is presented as a direct deduction to the carrying amount of the notes in the accompanying Consolidated Statements of Assets and Liabilities. The amortization of such costs is included in interest expense and credit facility fees in the accompanying Consolidated Statements of Operations.
Asset Acquisition	Asset Acquisition The CSL III Merger and Credit Fund II Purchase were accounted for under the asset acquisition method of accounting in accordance with ASC 805 – Business Combinations – Related Issues (“ASC Topic 805”), also referred to as “purchase accounting.” Under the asset acquisition method of accounting, acquiring assets in groups not only requires ascertaining the cost of the asset (or net assets), but also allocating that cost to the individual assets (or individual assets and liabilities) that make up the group. Per ASC Topic 805, assets are recognized based on their cost to the acquiring entity, which generally includes transaction costs of the asset acquisition, and no gain or loss is recognized unless the fair value of non-cash assets given as consideration differs from the assets’ carrying amounts on the acquiring entity’s books. The cost of the group of assets acquired in an asset acquisition is allocated to the individual assets acquired or liabilities assumed based on the relative fair values of net identifiable assets acquired other than “non-qualifying” assets (for example, cash), and does not give rise to goodwill. To the extent that the consideration paid to the CSL III shareholders or the members of acquired entities exceeded the relative fair values of the net identifiable assets acquired, other than “non-qualifying” assets, any such premium paid by the Company was further allocated to the cost of the assets acquired by the Company pro-rata to their relative fair value, other than “non-qualifying” assets, which are investments in loans, equity securities and forward currency contracts. Immediately following the completion of the CSL III Merger and the Credit Fund II Purchase, the Company recorded the acquired assets at their respective fair values and, as a result, the purchase premium or discount allocated to the cost basis of the assets acquired was immediately recognized as unrealized depreciation or appreciation on the Company’s Consolidated Statement of Operations. The purchase premium or discount allocated to investments in loan securities will amortize over the life of the loans through interest income, with a corresponding reversal of the unrealized depreciation/appreciation on the loans acquired through their ultimate disposition. Net increase (decrease) to investment income from the amortization of purchase premiums and discounts relating to asset acquisitions for the three months ended March 31, 2026 was $(178). The purchase premium or discount allocated to investments in equity securities and forward currency contracts will not amortize through interest income and, assuming no subsequent change to the fair value of such equity securities and disposition at fair value, the Company will recognize a realized loss or a reduction in realized gains with a corresponding reversal of the unrealized depreciation or appreciation upon disposition of the CSL III equity securities and forward currency contracts acquired.
Income Taxes	Income Taxes For federal income tax purposes, the Company has elected to be treated as a RIC under the Code, and intends to make the required distributions to its stockholders as specified therein. In order to qualify as a RIC, the Company must meet certain minimum distribution, source-of-income and asset diversification requirements. If such requirements are met, then the Company is generally required to pay income taxes only on the portion of its taxable income and gains it does not distribute. The minimum distribution requirements applicable to RICs require the Company to distribute to its stockholders at least 90% of its investment company taxable income (“ICTI”), as defined by the Code, each year. Depending on the level of ICTI earned in a tax year, the Company may choose to carry forward ICTI in excess of current year distributions into the next tax year. Any such carryover ICTI must be distributed before the end of that next tax year through a dividend declared prior to filing the final tax return related to the year which generated such ICTI. In addition, based on the excise distribution requirements, the Company is subject to a 4% nondeductible federal excise tax on undistributed income unless the Company distributes in a timely manner an amount at least equal to the sum of (1) 98% of its ordinary income for each calendar year, (2) 98.2% of capital gain net income (both long-term and short-term) for the one-year period ending October 31 in that calendar year and (3) any income realized, but not distributed, in the preceding year. For this purpose, however, any ordinary income or capital gain net income retained by the Company that is subject to corporate income tax is considered to have been distributed. For the three months ended March 31, 2026 and 2025, the Company incurred $441 and $676 in excise tax expense, respectively. The Company evaluates tax positions taken or expected to be taken in the course of preparing its unaudited consolidated financial statements to determine whether the tax positions are “more likely than not” to be sustained by the applicable tax authority. The SPV, CSL III SPV, Credit Fund II and the 2015-1 Issuer are disregarded entities for tax purposes and are consolidated with the tax return of the Company. All penalties and interest associated with income taxes, if any, are included in income tax expense.
Dividends and Distributions to Common Stockholders	Dividends and Distributions to Common Stockholders To the extent that the Company has taxable income available, the Company intends to make quarterly distributions to its common stockholders. Dividends and distributions to common stockholders are recorded on the record date. The amount to be distributed, if any, is determined by the Board of Directors each quarter and is generally based upon the taxable earnings estimated by management and available cash. Net realized capital gains, if any, are generally distributed at least annually, although the Company may decide to retain such capital gains for investment. Prior to July 5, 2017, the Company had an “opt in” dividend reinvestment plan. Effective on July 5, 2017, the Company converted the “opt in” dividend reinvestment plan to an “opt out” dividend reinvestment plan that provides for reinvestment of dividends and other distributions on behalf of the common stockholders, other than those common stockholders who have “opted out” of the plan. As a result of adopting the plan, if the Board of Directors authorizes, and the Company declares, a cash dividend or distribution, the common stockholders who have not elected to “opt out” of the dividend reinvestment plan will have their cash dividends or distributions automatically reinvested in additional shares of the Company’s common stock, rather than receiving cash. Each registered stockholder may elect to have such stockholder’s dividends and distributions distributed in cash rather than participate in the plan. For any registered stockholder that does not so elect, distributions on such stockholder’s shares will be reinvested by State Street Bank and Trust Company, the Company’s plan administrator, in additional shares. The number of shares to be issued to the stockholder will be determined based on the total dollar amount of the cash distribution payable, net of applicable withholding taxes. The Company intends to use primarily newly issued shares to implement the plan so long as the market value per share is equal to or greater than the net asset value per share on the relevant valuation date. If the market value per share is less than the net asset value per share on the relevant valuation date, the plan administrator would implement the plan through the purchase of common stock on behalf of participants in the open market, unless the Company instructs the plan administrator otherwise.
Functional Currency	Functional Currency The functional currency of the Company is the U.S. Dollar. Investments are generally made in the local currency of the country in which the investments are domiciled and are translated into U.S. Dollars with foreign currency translation gains or losses recorded within net change in unrealized appreciation (depreciation) on investments in the accompanying Consolidated Statements of Operations. Foreign currency translation gains and losses on non-investment assets and liabilities are separately reflected in the accompanying Consolidated Statements of Operations.
Earnings Per Common Share	Earnings Per Common Share The Company computes earnings per common share in accordance with ASC 260, Earnings Per Share (“ASC 260”). Basic earnings per common share is calculated by dividing the net increase (decrease) in net assets resulting from operations attributable to common stock by the weighted average number of shares of common stock outstanding. Diluted earnings per common share reflects the assumed conversion of all dilutive securities.
Segment Reporting	Segment Reporting In accordance with ASC Topic 280 - Segment Reporting (“ASC 280”), the Company has determined that it has a single operating and reporting segment. As a result, the Company’s segment accounting policies are the same as described herein and the Company does not have any intra-segment sales and transfers of assets.
Recent Accounting Standards Updates	Recent Accounting Standards Updates In November 2024, the FASB issued ASU 2024-03, which requires disaggregated disclosure of income statement expense for public entities. The ASU does not change the expense captions an entity presents on the face of the income statement; rather, it requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. In January 2025, the FASB issued ASU 2025-01, which revises the effective date of ASU 2024-03. The amendments are effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. The Company is currently evaluating the impact of this guidance. In November 2024, the FASB issued ASU 2024-04, which amends ASC 470-20 to clarify the requirements related to accounting for the settlement of a debt instrument as an induced conversion. The amendments are effective for fiscal years and interim periods within fiscal years beginning after December 15, 2025. The Company notes this guidance does not have a material impact on its unaudited consolidated financial statements. In November 2025, the FASB issued ASU 2025-09, which is intended to better align hedge accounting with entities’ risk management activities. The amendments expand and clarify hedge accounting guidance for certain financial and nonfinancial risk components and align the recognition and presentation of the effects of hedging instruments and hedged items in the financial statements. The amendments are effective for fiscal years beginning after December 15, 2026, including interim periods within those fiscal years, with early adoption permitted. The Company does not expect this guidance to have a material impact on its unaudited consolidated financial statements.

SIGNIFICANT ACCOUNTING POLICIES (Policies)

3 Months Ended

Mar. 31, 2026

The unaudited consolidated financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). The Company is an investment company for the purposes of accounting and financial reporting in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946, Financial Services—Investment Companies (“ASC 946”). The unaudited consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, the SPV, the 2015-1 Issuer, the CSL III SPV, and the Credit Fund II. All significant intercompany balances and transactions have been eliminated. U.S. GAAP for an investment company requires investments to be recorded at fair value. The carrying value for all other assets and liabilities approximates their fair value.

The unaudited consolidated financial statements have been prepared in accordance with U.S. GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Articles 6 and 10 of Regulation S-X. Accordingly, certain disclosures accompanying the annual consolidated financial statements prepared in accordance with U.S. GAAP are omitted. In the opinion of management, all adjustments considered necessary for the fair presentation of unaudited consolidated financial statements for the interim periods presented have been included. These adjustments are of a normal, recurring nature. This Form 10-Q should be read in conjunction with the Company's annual report on Form 10-K for the year ended December 31, 2025. The results of operations for the three months ended March 31, 2026 are not necessarily indicative of the operating results to be expected for the full year.

Certain prior period disclosures within the Consolidated Statement of Cash flows have been amended to conform to the current period presentation.

Use of Estimates

The preparation of unaudited consolidated financial statements in conformity with U.S. GAAP requires management to make assumptions and estimates 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 revenues and expenses during the reporting period. Management’s estimates are based on historical experiences and other factors, including expectations of future events that management believes to be reasonable under the circumstances. It also requires management to exercise judgment in the process of applying the Company’s accounting policies. Assumptions and estimates regarding the valuation of investments and their resulting impact on base management and incentive fees involve a higher degree of judgment and complexity and these

assumptions and estimates may be significant to the unaudited consolidated financial statements. Actual results could differ from these estimates and such differences could be material.

Investments

Investment transactions are recorded on the trade date. Realized gains or losses are measured by the difference between the net proceeds from the repayment or sale and the amortized cost basis of the investment at the time of exit using the specific identification method without regard to unrealized appreciation or depreciation previously recognized, and includes investments charged off during the period, net of recoveries. Net change in unrealized appreciation or depreciation on investments as presented in the accompanying Consolidated Statements of Operations reflects the net change in the fair value of investments, including the reversal of previously recorded unrealized appreciation or depreciation when gains or losses are realized. See Note 3, Fair Value Measurements, to these unaudited consolidated financial statements for further information about fair value measurements.

Derivative Instruments

The Company follows the guidance in Topic 815, Derivatives and Hedging (“ASC 815”), when accounting for derivative instruments. The Company recognizes all derivative instruments at fair value as either assets or liabilities in its unaudited consolidated financial statements. Derivative instruments are measured in terms of the notional contract amount and derive their value based upon one or more underlying instruments. Derivative instruments are subject to various risks similar to non-derivative instruments including market, credit, liquidity, and operational risks. The Company manages these risks on an aggregate basis as part of its risk management process.

The Company has in the past and may in the future use forward currency contracts to economically hedge the currency exposure associated with certain foreign-denominated investments. The use of forward currency contracts does not eliminate fluctuations in the price of the underlying securities the Company owns or intends to acquire but establishes a rate of exchange in advance. Until the contracts are closed, fluctuations in the value of these contracts are measured by the difference in the exchange rates on the contract date and reporting date and are recorded as net change in unrealized gain (loss) on forward currency contracts within the Consolidated Statements of Operations. When the contracts are closed, realized gains (losses) are recorded as realized gain (loss) on forward currency contracts within the Consolidated Statements of Operations. The forward currency contracts are recorded at fair value on the Consolidated Statements of Assets and Liabilities by counterparty on a net basis, not taking into account collateral posted which is recorded separately, if applicable. The change in fair value of the forward currency contracts is reflected as net change in unrealized (gain) loss on forward currency contracts within the Consolidated Statements of Cash Flows. Refer to Note 8, Derivative Instruments, to these unaudited consolidated financial statements for further information.

The Company uses interest rate swaps to hedge some of the Company's fixed rate debt. The Company designated the interest rate swaps as the hedging instrument in an effective hedge accounting relationship and therefore the periodic payments and receipts are recognized as components of interest expense and credit facility fees within the accompanying Consolidated Statements of Operations. Depending on the nature of the balance at the end of the period, the fair value of the interest rate swap is either an asset and included in derivative assets, at fair value on the accompanying Consolidated Statements of Assets and Liabilities or a liability and included in derivative liabilities, at fair value on accompanying Consolidated Statements of Assets and Liabilities. The change in fair value of the interest rate swap is offset by a change in the carrying value of the fixed rate debt. The change in fair value of the interest rate swap is reflected as net change in unrealized gain (loss) on interest rate swaps within the Consolidated Statements of Cash Flows.

Any amounts held by the Company in a separate account to cover collateral obligations to the counterparty under the terms of the ISDA Master Agreement (as defined in Note 8, Derivative Instruments, to these unaudited consolidated financial statements) and interest rate swap agreements are included in cash, cash equivalents, and restricted cash on the accompanying Consolidated Statements of Assets and Liabilities. Any amounts paid to and held by the counterparty to cover collateral obligations under the terms of the interest rate swap agreement are included in prepaid expenses and other assets on the accompanying Consolidated Statements of Assets and Liabilities. Any amounts paid from the counterparty due to market value fluctuations to cover collateral under the terms of the interest rate swap agreement are included in other accrued expenses and liabilities on accompanying Consolidated Statements of Assets and Liabilities.

Cash, Cash Equivalents and Restricted Cash

Cash, cash equivalents and restricted cash consist of demand deposits and highly liquid investments (e.g., money market funds, U.S. Treasury notes) with original maturities of three months or less. Cash equivalents are carried at amortized cost, which approximates fair value. The Company’s cash, cash equivalents and restricted cash are held with two large financial

institutions and cash held at each financial institution may, at times, exceed the Federal Deposit Insurance Corporation insured limit. As of March 31, 2026 and December 31, 2025, the Company held restricted cash balances of $28,780 and $31,474, respectively. Restricted cash balances represent amounts that are collected and held by trustees appointed by the Company for payment of interest expense and principal on the outstanding borrowings and reinvestment into new assets. Restricted cash balances also include amounts held by the Company in a separate account to cover collateral obligations under the terms of any interest rate swap agreements. The amounts are held by the trustees as custodians of the assets securing certain of the Company’s financing transactions.

Revenue Recognition

Interest from Investments

Interest income is recorded on an accrual basis and includes the accretion of discounts and amortization of premiums. Discounts from and premiums to par value on debt investments purchased are accreted/amortized into interest income over the life of the respective security using the effective interest method. The amortized cost of debt investments represents the original cost, including origination fees and upfront fees received that are deemed to be an adjustment to yield, adjusted for the accretion of discounts and amortization of premiums, if any.

The Company may have loans in its portfolio that contain payment-in-kind (“PIK”) provisions. PIK income represents interest that is accrued and recorded as interest income at the contractual rates, increases the loan principal on the respective capitalization dates, and is generally due at maturity. As of March 31, 2026 and December 31, 2025, the fair value of the loans in the portfolio with PIK provisions was $390,789 and $305,090, respectively, which represents approximately 17.2% and 12.4%, respectively, of total investments at fair value. For the three months ended March 31, 2026 and 2025, the Company earned $6,481 and $5,379 in PIK income, respectively.

Dividend Income

Dividend income from the investment funds, Credit Fund and Credit Fund II, Structured Credit Partners, and other investments funds, if any, is recorded on the record date for the investment fund to the extent that such amounts are payable by the investment funds and are expected to be collected.

Other Income

Other income may include income such as consent, waiver, amendment, unused, underwriting, arranger and prepayment fees associated with the Company’s investment activities as well as any fees for managerial assistance services rendered by the Company to the portfolio companies. Such fees are recognized as income when earned or the services are rendered. The Company may receive fees for guaranteeing the outstanding debt of a portfolio company. Such fees are amortized into other income over the life of the guarantee. The unamortized amount, if any, is included in prepaid expenses and other assets in the accompanying Consolidated Statements of Assets and Liabilities. For the three months ended March 31, 2026 and 2025, the Company earned $2,595 and $951, respectively, in other income, primarily from amendment fees, prepayment fees and unused commitment fees.

Non-Accrual Income

Loans are generally placed on non-accrual status when principal or interest payments are past due or when there is reasonable doubt that principal or interest will be collected in full. Accrued and unpaid interest is generally reversed when a loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment regarding collectability. Non-accrual loans are restored to accrual status when past due principal and interest are current or there is no longer any reasonable doubt that such principal or interest will be collected in full and, in management’s judgment, are likely to remain current. Management may determine not to place a loan on non-accrual status if the loan has sufficient collateral value and is in the process of collection.

Credit Facilities, Senior Notes, and Debt Securitization – Related Costs, Expenses and Deferred Financing Costs

The Credit Facilities, the 2015-1N Debt, and the Senior Notes, each as defined within Note 9, Borrowings, to these unaudited consolidated financial statements, are recorded at carrying value, which approximates fair value. Interest expense and

unused commitment fees on the Credit Facilities are recorded on an accrual basis. Unused commitment fees are included in interest expense and credit facility fees in the accompanying Consolidated Statements of Operations.

Deferred financing costs include capitalized expenses related to the closing or amendments of the Credit Facilities. Amortization of deferred financing costs for the Credit Facilities is computed on the straight-line basis over the respective term of each Credit Facility. The unamortized balance of such costs is included in prepaid expenses and other assets in the accompanying Consolidated Statements of Assets and Liabilities. The amortization of such costs is included in interest expense and credit facility fees in the accompanying Consolidated Statements of Operations.

Debt issuance costs include capitalized expenses including structuring and arrangement fees related to the offering of the 2015-1N Debt and Senior Notes. Amortization of debt issuance costs for the notes is computed on the effective yield method over the term of the notes. The unamortized balance of such costs is presented as a direct deduction to the carrying amount of the notes in the accompanying Consolidated Statements of Assets and Liabilities. The amortization of such costs is included in interest expense and credit facility fees in the accompanying Consolidated Statements of Operations.

Asset Acquisition

The CSL III Merger and Credit Fund II Purchase were accounted for under the asset acquisition method of accounting in accordance with ASC 805 – Business Combinations – Related Issues (“ASC Topic 805”), also referred to as “purchase accounting.” Under the asset acquisition method of accounting, acquiring assets in groups not only requires ascertaining the cost of the asset (or net assets), but also allocating that cost to the individual assets (or individual assets and liabilities) that make up the group. Per ASC Topic 805, assets are recognized based on their cost to the acquiring entity, which generally includes transaction costs of the asset acquisition, and no gain or loss is recognized unless the fair value of non-cash assets given as consideration differs from the assets’ carrying amounts on the acquiring entity’s books.

The cost of the group of assets acquired in an asset acquisition is allocated to the individual assets acquired or liabilities assumed based on the relative fair values of net identifiable assets acquired other than “non-qualifying” assets (for example, cash), and does not give rise to goodwill. To the extent that the consideration paid to the CSL III shareholders or the members of acquired entities exceeded the relative fair values of the net identifiable assets acquired, other than “non-qualifying” assets, any such premium paid by the Company was further allocated to the cost of the assets acquired by the Company pro-rata to their relative fair value, other than “non-qualifying” assets, which are investments in loans, equity securities and forward currency contracts. Immediately following the completion of the CSL III Merger and the Credit Fund II Purchase, the Company recorded the acquired assets at their respective fair values and, as a result, the purchase premium or discount allocated to the cost basis of the assets acquired was immediately recognized as unrealized depreciation or appreciation on the Company’s Consolidated Statement of Operations. The purchase premium or discount allocated to investments in loan securities will amortize over the life of the loans through interest income, with a corresponding reversal of the unrealized depreciation/appreciation on the loans acquired through their ultimate disposition. Net increase (decrease) to investment income from the amortization of purchase premiums and discounts relating to asset acquisitions for the three months ended March 31, 2026 was $(178). The purchase premium or discount allocated to investments in equity securities and forward currency contracts will not amortize through interest income and, assuming no subsequent change to the fair value of such equity securities and disposition at fair value, the Company will recognize a realized loss or a reduction in realized gains with a corresponding reversal of the unrealized depreciation or appreciation upon disposition of the CSL III equity securities and forward currency contracts acquired.

Income Taxes

For federal income tax purposes, the Company has elected to be treated as a RIC under the Code, and intends to make the required distributions to its stockholders as specified therein. In order to qualify as a RIC, the Company must meet certain minimum distribution, source-of-income and asset diversification requirements. If such requirements are met, then the Company is generally required to pay income taxes only on the portion of its taxable income and gains it does not distribute.

The minimum distribution requirements applicable to RICs require the Company to distribute to its stockholders at least 90% of its investment company taxable income (“ICTI”), as defined by the Code, each year. Depending on the level of ICTI earned in a tax year, the Company may choose to carry forward ICTI in excess of current year distributions into the next tax year. Any such carryover ICTI must be distributed before the end of that next tax year through a dividend declared prior to filing the final tax return related to the year which generated such ICTI.

In addition, based on the excise distribution requirements, the Company is subject to a 4% nondeductible federal excise tax on undistributed income unless the Company distributes in a timely manner an amount at least equal to the sum of (1) 98% of its ordinary income for each calendar year, (2) 98.2% of capital gain net income (both long-term and short-term) for the one-year period ending October 31 in that calendar year and (3) any income realized, but not distributed, in the preceding year. For this purpose, however, any ordinary income or capital gain net income retained by the Company that is subject to corporate income tax is considered to have been distributed. For the three months ended March 31, 2026 and 2025, the Company incurred $441 and $676 in excise tax expense, respectively.

The Company evaluates tax positions taken or expected to be taken in the course of preparing its unaudited consolidated financial statements to determine whether the tax positions are “more likely than not” to be sustained by the applicable tax authority. The SPV, CSL III SPV, Credit Fund II and the 2015-1 Issuer are disregarded entities for tax purposes and are consolidated with the tax return of the Company. All penalties and interest associated with income taxes, if any, are included in income tax expense.

Dividends and Distributions to Common Stockholders

To the extent that the Company has taxable income available, the Company intends to make quarterly distributions to its common stockholders. Dividends and distributions to common stockholders are recorded on the record date. The amount to be distributed, if any, is determined by the Board of Directors each quarter and is generally based upon the taxable earnings estimated by management and available cash. Net realized capital gains, if any, are generally distributed at least annually, although the Company may decide to retain such capital gains for investment.

Prior to July 5, 2017, the Company had an “opt in” dividend reinvestment plan. Effective on July 5, 2017, the Company converted the “opt in” dividend reinvestment plan to an “opt out” dividend reinvestment plan that provides for reinvestment of dividends and other distributions on behalf of the common stockholders, other than those common stockholders who have “opted out” of the plan. As a result of adopting the plan, if the Board of Directors authorizes, and the Company declares, a cash dividend or distribution, the common stockholders who have not elected to “opt out” of the dividend reinvestment plan will have their cash dividends or distributions automatically reinvested in additional shares of the Company’s common stock, rather than receiving cash. Each registered stockholder may elect to have such stockholder’s dividends and distributions distributed in cash rather than participate in the plan. For any registered stockholder that does not so elect, distributions on such stockholder’s shares will be reinvested by State Street Bank and Trust Company, the Company’s plan administrator, in additional shares. The number of shares to be issued to the stockholder will be determined based on the total dollar amount of the cash distribution payable, net of applicable withholding taxes. The Company intends to use primarily newly issued shares to implement the plan so long as the market value per share is equal to or greater than the net asset value per share on the relevant valuation date. If the market value per share is less than the net asset value per share on the relevant valuation date, the plan administrator would implement the plan through the purchase of common stock on behalf of participants in the open market, unless the Company instructs the plan administrator otherwise.

Functional Currency

The functional currency of the Company is the U.S. Dollar. Investments are generally made in the local currency of the country in which the investments are domiciled and are translated into U.S. Dollars with foreign currency translation gains or losses recorded within net change in unrealized appreciation (depreciation) on investments in the accompanying Consolidated Statements of Operations. Foreign currency translation gains and losses on non-investment assets and liabilities are separately reflected in the accompanying Consolidated Statements of Operations.

Earnings Per Common Share

The Company computes earnings per common share in accordance with ASC 260, Earnings Per Share (“ASC 260”). Basic earnings per common share is calculated by dividing the net increase (decrease) in net assets resulting from operations attributable to common stock by the weighted average number of shares of common stock outstanding. Diluted earnings per common share reflects the assumed conversion of all dilutive securities.

Segment Reporting

In accordance with ASC Topic 280 - Segment Reporting (“ASC 280”), the Company has determined that it has a single operating and reporting segment. As a result, the Company’s segment accounting policies are the same as described herein and the Company does not have any intra-segment sales and transfers of assets.

Recent Accounting Standards Updates

In November 2024, the FASB issued ASU 2024-03, which requires disaggregated disclosure of income statement expense for public entities. The ASU does not change the expense captions an entity presents on the face of the income statement; rather, it requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. In January 2025, the FASB issued ASU 2025-01, which revises the effective date of ASU 2024-03. The amendments are effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. The Company is currently evaluating the impact of this guidance.

In November 2024, the FASB issued ASU 2024-04, which amends ASC 470-20 to clarify the requirements related to accounting for the settlement of a debt instrument as an induced conversion. The amendments are effective for fiscal years and interim periods within fiscal years beginning after December 15, 2025. The Company notes this guidance does not have a material impact on its unaudited consolidated financial statements.

In November 2025, the FASB issued ASU 2025-09, which is intended to better align hedge accounting with entities’ risk management activities. The amendments expand and clarify hedge accounting guidance for certain financial and nonfinancial risk components and align the recognition and presentation of the effects of hedging instruments and hedged items in the financial statements. The amendments are effective for fiscal years beginning after December 15, 2026, including interim periods within those fiscal years, with early adoption permitted. The Company does not expect this guidance to have a material impact on its unaudited consolidated financial statements.
