Oaktree Specialty Lending Corp

Note 1. Organization

Oaktree Specialty Lending Corporation (together with its consolidated subsidiaries, the "Company") is a specialty finance company that looks to provide customized, one-stop credit solutions to companies with limited access to public or syndicated capital markets. The Company was formed in late 2007 and operates as a closed-end, externally managed, non-diversified management investment company that has elected to be regulated as a Business Development Company under the Investment Company Act. The Company has qualified and elected to be treated as a regulated investment company ("RIC") under the Internal Revenue Code of 1986, as amended (the "Code"), for U.S. federal income tax purposes.

The Company's investment objective is to generate current income and capital appreciation by providing companies with flexible and innovative financing solutions, including first and second lien loans, unsecured and mezzanine loans, bonds, preferred equity and certain equity co-investments. The Company may also seek to generate capital appreciation and income through secondary investments at discounts to par in either private or syndicated transactions.

The Company is externally managed by Oaktree Fund Advisors, LLC ("Oaktree"), pursuant to an investment advisory agreement between the Company and Oaktree (as amended and restated, the "Investment Advisory Agreement"). Oaktree is an affiliate of Oaktree Capital Management, L.P. ("OCM"), the Company's external investment adviser from October 17, 2017 through May 3, 2020. Oaktree Fund Administration, LLC ("Oaktree Administrator"), a subsidiary of OCM, provides certain administrative and other services necessary for the Company to operate pursuant to an administration agreement between the Company and Oaktree Administrator (the "Administration Agreement"). See Note 10. In 2019, Brookfield Corporation (formerly known as Brookfield Asset Management Inc. and collectively with its affiliates, "Brookfield") acquired a majority economic interest in Oaktree Capital Group, LLC. Oaktree and its affiliates operate as an independent business within Brookfield, with their own product offerings and investment, marketing and support teams.

On March 19, 2021, the Company acquired Oaktree Strategic Income Corporation (“OCSI”) pursuant to that certain Agreement and Plan of Merger (the “OCSI Merger Agreement”), dated as of October 28, 2020, by and among OCSI, the Company, Lion Merger Sub, Inc., a wholly-owned subsidiary of the Company, and, solely for the limited purposes set forth therein, Oaktree. Pursuant to the OCSI Merger Agreement, OCSI was merged with and into the Company in a two-step transaction, with the Company as the surviving company (the "OCSI Merger”).

On January 23, 2023, the Company acquired Oaktree Strategic Income II, Inc. (“OSI2”) pursuant to that certain Agreement and Plan of Merger (the “OSI2 Merger Agreement”), dated as of September 14, 2022, by and among OSI2, the Company, Project Superior Merger Sub, Inc., a wholly-owned subsidiary of the Company, and, solely for the limited purposes set forth therein, Oaktree. Pursuant to the OSI2 Merger Agreement, OSI2 was merged with and into the Company in a two-step transaction with the Company as the surviving company (the “OSI2 Merger”).

Note 2. Significant Accounting Policies

Basis of Presentation:

The Consolidated Financial Statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and pursuant to the requirements for reporting on Form 10-K and Regulation S-X. All intercompany balances and transactions have been eliminated. The Company is an investment company following the accounting and reporting guidance in ASC Topic 946, Financial Services - Investment Companies ("ASC 946").

Certain prior period amounts have been reclassified to conform to the current period presentation. All per share amounts and common shares outstanding have been retroactively adjusted as necessary to reflect the Company's 1-for-3 reverse stock split completed on January 20, 2023 and effective as of the commencement of trading on January 23, 2023.

Use of Estimates:

The preparation of the financial statements in conformity with GAAP requires management to make certain estimates and assumptions affecting amounts reported in the financial statements and accompanying notes. These estimates are based on the information that is currently available to the Company and on various other assumptions that the Company believes to be reasonable under the circumstances. Changes in the economic and political environments, financial markets and any other parameters used in determining these estimates could cause actual results to differ and such differences could be material. Significant estimates include the valuation of investments and revenue recognition.

Consolidation:

The accompanying Consolidated Financial Statements include the accounts of Oaktree Specialty Lending Corporation and its consolidated subsidiaries. Each consolidated subsidiary is wholly-owned and, as such, consolidated into the Consolidated Financial Statements. Certain subsidiaries that hold investments are treated as pass through entities for U.S. federal income tax purposes. The assets of certain of the consolidated subsidiaries are not directly available to satisfy the claims of the creditors of Oaktree Specialty Lending Corporation or any of its other subsidiaries.

As an investment company, portfolio investments held by the Company are not consolidated into the Consolidated Financial Statements but rather are included on the Statements of Assets and Liabilities as investments at fair value.

Fair Value Measurements:

Oaktree, as the valuation designee of the Company's Board of Directors pursuant to Rule 2a-5 under the Investment Company Act, determines the fair value of the Company's assets on at least a quarterly basis in accordance with ASC 820. ASC 820 defines fair value as the amount 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. A liability's fair value is defined as the amount that would be paid to transfer the liability to a new obligor, not the amount that would be paid to settle the liability with the creditor. ASC 820 prioritizes the use of observable market prices over entity-specific inputs. Where observable prices or inputs are not available or reliable, valuation techniques are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the investments or market and the investments' complexity.

Hierarchical levels, defined by ASC 820 and directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities, are as follows:

•Level 1 — Unadjusted, quoted prices in active markets for identical assets or liabilities as of the measurement date.

•Level 2 — Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data at the measurement date for substantially the full term of the assets or liabilities.

•Level 3 — Unobservable inputs that reflect Oaktree's best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

If inputs used to measure fair value fall into different levels of the fair value hierarchy, an investment's level is based on the lowest level of input that is significant to the fair value measurement. Oaktree'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. This includes investment securities that are valued using "bid" and "ask" prices obtained from independent third party pricing services or directly from brokers. These investments may be classified as Level 3 because the quoted prices may be indicative in nature for securities that are in an inactive market, may be for similar securities or may require adjustments for investment-specific factors or restrictions.

Financial instruments with readily available quoted prices generally will have a higher degree of market price observability and a lesser degree of judgment inherent in measuring fair value. As such, Oaktree obtains and analyzes readily available market quotations provided by pricing vendors and brokers for all of the Company's investments for which quotations are available. In determining the fair value of a particular investment, pricing vendors and brokers use observable market information, including both binding and non-binding indicative quotations.

Oaktree seeks to obtain at least two quotations for the subject or similar securities, typically from pricing vendors. If Oaktree is unable to obtain two quotes from pricing vendors, or if the prices obtained from pricing vendors are not within Oaktree's set threshold, Oaktree seeks to obtain a quote directly from a broker making a market for the asset. Oaktree evaluates the quotations provided by pricing vendors and brokers based on available market information, including trading activity of the subject or similar securities, or by performing a comparable security analysis to ensure that fair values are reasonably estimated. Oaktree also performs back-testing of valuation information obtained from pricing vendors and brokers against actual prices received in transactions. In addition to ongoing monitoring and back-testing, Oaktree performs due diligence procedures over pricing vendors to understand their methodology and controls to support their use in the valuation process. Generally, Oaktree does not adjust any of the prices received from these sources.

If the quotations obtained from pricing vendors or brokers are determined to not be reliable or are not readily available, Oaktree values such investments using any of three different valuation techniques. The first valuation technique is the transaction precedent technique, which utilizes recent or expected future transactions of the investment to determine fair value, to the extent applicable. The second valuation technique is an analysis of the enterprise value ("EV") of the portfolio company. EV 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 EV analysis is typically performed to determine (i) the value of equity investments, (ii) whether there is credit impairment for debt investments and (iii) the value for debt investments that the Company is deemed to control under the Investment Company Act. To estimate the EV of a portfolio company, Oaktree analyzes various factors, including the portfolio company’s historical and projected financial results, macroeconomic impacts on the company and competitive dynamics in the company’s industry. Oaktree also utilizes some or all of the following information based on the individual circumstances of the portfolio company: (i) valuations of comparable public companies, (ii) recent sales of private and public comparable companies in similar industries or having similar business or earnings characteristics, (iii) purchase prices as a multiple of their earnings or cash flow, (iv) the portfolio company’s ability to meet its forecasts and its business prospects, (v) a discounted cash flow analysis, (vi) estimated liquidation or collateral value of the portfolio company's assets and (vii) offers from third parties to buy the portfolio company. Oaktree may probability weight potential sale outcomes with respect to a portfolio company when uncertainty exists as of the valuation date. The third valuation technique is a market yield technique, which is typically performed for non-credit impaired debt investments. In the market yield technique, a current price is imputed for the investment based upon an assessment of the expected market yield for a similarly structured investment with a similar level of risk, and Oaktree considers the current contractual interest rate, the capital structure and other terms of the investment relative to risk of the company and the specific investment. A key determinant of risk, among other things, is the leverage through the investment relative to the EV of the portfolio company. As debt investments held by the Company are substantially illiquid with no active transaction market, Oaktree depends on primary market data, including newly funded transactions and industry specific market movements, as well as secondary market data with respect to high yield debt instruments and syndicated loans, as inputs in determining the appropriate market yield, as applicable.

In accordance with ASC 820-10, certain investments that qualify as investment companies in accordance with ASC 946 may be valued using net asset value as a practical expedient for fair value. Consistent with FASB guidance under ASC 820, these investments are excluded from the hierarchical levels. These investments are generally not redeemable.

Oaktree estimates the fair value of certain privately held warrants using a Black Scholes pricing model, which includes an analysis of various factors and subjective assumptions, including the current stock price (by using an EV analysis as described above), the expected period until exercise, expected volatility of the underlying stock price, expected dividends and the risk free rate. Changes in the subjective input assumptions can materially affect the fair value estimates.

Rule 2a-5 under the Investment Company Act permits boards of directors of registered investment companies and Business Development Companies to either (i) choose to determine fair value in good faith or (ii) designate a valuation designee tasked with determining fair value in good faith, subject to the board’s oversight. The Company's Board of Directors has designated Oaktree to serve as its valuation designee effective September 8, 2022.

Oaktree undertakes a multi-step valuation process each quarter in connection with determining the fair value of the Company's investments:

•The quarterly valuation process begins with each portfolio company or investment being initially valued by Oaktree's valuation team;

•Preliminary valuations are then reviewed and discussed with management of Oaktree;

•Separately, independent valuation firms prepare valuations of the Company's investments, on a selected basis, for which market quotations are not readily available or are readily available but deemed not reflective of the fair value of the investment, and submit the reports to the Company and provide such reports to Oaktree;

•Oaktree compares and contrasts its preliminary valuations to the valuations of the independent valuation firms and prepares a valuation report for the Audit Committee;

•The Audit Committee reviews the valuation report with Oaktree, and Oaktree responds and supplements the valuation report to reflect any discussions between Oaktree and the Audit Committee; and

•Oaktree, as valuation designee, determines the fair value of each investment in the Company's portfolio.

The fair value of the Company's investments as of September 30, 2024 and September 30, 2023 was determined by Oaktree, as the Company's valuation designee. The Company has and will continue to engage independent valuation firms to provide assistance regarding the determination of the fair value of a portion of its portfolio securities for which market quotations are not readily available or are readily available but deemed not reflective of the fair value of the investment each quarter.

Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of the Company’s investments may fluctuate from period to period. Because of the inherent uncertainty of valuation, these estimated values may differ significantly from the values that would have been reported had a ready market for the investments existed, and it is reasonably possible that the difference could be material.

With the exception of the line items entitled "deferred financing costs," "deferred offering costs," "other assets," "deferred tax liability," "credit facilities payable" and "unsecured notes payable," which are reported at amortized cost, all assets and liabilities approximate fair value on the Consolidated Statements of Assets and Liabilities. The carrying value of the line items titled "interest, dividends and fees receivable," "due from portfolio companies," "receivables from unsettled transactions," "due from broker," "accounts payable, accrued expenses and other liabilities," "base management fee and incentive fee payable," "due to affiliate," "interest payable " and "payables from unsettled transactions" approximate fair value due to their short maturities.

Foreign Currency Translation:

The accounting records of the Company are maintained in U.S. dollars. All assets and liabilities denominated in foreign currencies are translated into U.S. dollars based on the prevailing foreign exchange rate on the reporting date. The Company does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. The Company’s investments in foreign securities may involve certain risks, including foreign exchange restrictions, expropriation, taxation or other political, social or economic risks, all of which could affect the market and/or credit risk of the investment. In addition, changes in the relationship of foreign currencies to the U.S. dollar can significantly affect the value of these investments and therefore the earnings of the Company.

Derivative Instruments:

Foreign Currency Forward Contracts

The Company uses foreign currency forward contracts to reduce the Company's exposure to fluctuations in the value of foreign currencies. In a foreign currency forward contract, the Company agrees to receive or deliver a fixed quantity of one currency for another at a pre-determined price at a future date. Foreign currency forward contracts are marked-to-market at the applicable forward rate. Unrealized appreciation (depreciation) on foreign currency forward contracts is recorded within derivative assets or derivative liabilities 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. Purchases and settlements of foreign currency forward contracts having the same settlement date and counterparty are generally settled net and any realized gains or losses are recognized on the settlement date. The Company does not utilize hedge accounting with respect to foreign currency forward contracts and, as such, the Company recognizes its foreign currency forward contracts at fair value with changes included in the net unrealized appreciation (depreciation) on the Consolidated Statements of Operations.

Interest Rate Swaps

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 instruments in an effective hedge accounting relationship, and therefore the periodic payments are recognized as components of interest expense in the Consolidated Statements of Operations. Depending on the nature of the balance at period end, the fair value of each interest rate swap is either included as a derivative asset or derivative liability on the Company's Consolidated Statements of Assets and Liabilities. The change in fair value of the interest rate swaps is offset by a change in the carrying value of the fixed rate debt. Any amounts paid to the counterparty to cover collateral obligations under the terms of the interest rate swap agreements are included in due from broker on the Company's Consolidated Statements of Assets and Liabilities.

Investment Income:

Interest Income

Interest income, adjusted for accretion of original issue discount ("OID"), is recorded on an accrual basis to the extent that such amounts are expected to be collected. The Company stops accruing interest on investments when it is determined that interest is no longer collectible. Investments that are expected to pay regularly scheduled interest in cash are generally placed on non-accrual status when there is reasonable doubt that principal or interest cash payments will be collected. Cash interest payments received on investments may be recognized as income or a return of capital depending upon management’s judgment. A non-accrual investment is restored to accrual status if past due principal and interest are paid in cash and the portfolio company, in management’s judgment, is likely to continue timely payment of its remaining obligations. As of September 30, 2024, there were nine investments on non-accrual status that in aggregate represented 4.9% and 4.0% of total debt investments at cost and fair value, respectively. As of September 30, 2023, there were four investments on non-accrual status that in aggregate represented 2.4% and 1.8% of total debt investments at cost and fair value, respectively.

In connection with its investment in a portfolio company, the Company sometimes receives nominal cost equity that is valued as part of the negotiation process with the portfolio company. When the Company receives nominal cost equity, the Company allocates its cost basis in the investment between debt securities and the nominal cost equity at the time of origination. Any resulting discount from recording the loan, or otherwise purchasing a security at a discount, is accreted into interest income over the life of the loan.

PIK Interest Income

The Company's investments in debt securities may contain PIK interest provisions. PIK interest, which generally represents contractually deferred interest added to the loan balance that is generally due at the end of the loan term, is generally recorded on the accrual basis to the extent such amounts are expected to be collected. The Company generally ceases accruing PIK interest if there is insufficient value to support the accrual or if the Company does not expect the portfolio company to be able to pay all principal and interest due. The Company's decision to cease accruing PIK interest on a loan or debt security involves subjective judgments and determinations based on available information about a particular portfolio company, including whether the portfolio company is current with respect to its payment of principal and interest on its loans and debt securities; financial statements and financial projections for the portfolio company; the Company's assessment of the portfolio company's business development success; information obtained by the Company in connection with periodic formal update interviews with the portfolio company's management and, if appropriate, the private equity sponsor; and information about the general economic and market conditions in which the portfolio company operates. The Company's determination to cease accruing PIK interest is generally made well before the Company's full write-down of a loan or debt security. In addition, if it is subsequently determined that the Company will not be able to collect any previously accrued PIK interest, the fair value of the loans or debt securities would be reduced by the amount of such previously accrued, but uncollectible, PIK interest. The accrual of PIK interest on the Company’s debt investments increases the recorded cost basis of these investments in the Consolidated Financial Statements including for purposes of computing the capital gains incentive fee payable by the Company to Oaktree. To maintain its status as a RIC, certain income from PIK interest may be required to be distributed to the Company’s stockholders, even though the Company has not yet collected the cash and may never do so.

Fee Income

Oaktree or its affiliates may provide financial advisory services to portfolio companies and, in return, the Company may receive fees for capital structuring services. These fees are generally non-recurring and are recognized by the Company upon the investment closing date. The Company may also receive additional fees in the ordinary course of business, including servicing, amendment, exit and prepayment fees, which are classified as fee income and recognized as they are earned or the services are rendered.

Dividend Income

The Company generally recognizes dividend income on the ex-dividend date for public securities and the record date for private equity investments. Distributions received from private equity investments are evaluated to determine if the distribution should be recorded as dividend income or a return of capital. Generally, the Company will not record distributions from private equity investments as dividend income unless there are sufficient earnings at the portfolio company prior to the distribution. Distributions that are classified as a return of capital are recorded as a reduction in the cost basis of the investment.

Cash and Cash Equivalents and Restricted Cash:

Cash and cash equivalents consist of demand deposits and highly liquid investments with maturities of three months or less when acquired. The Company places its cash and cash equivalents and restricted cash with financial institutions and, at times, cash held in bank accounts exceeds the Federal Deposit Insurance Corporation ("FDIC") insurance limit. Cash and cash equivalents are included on the Company's Consolidated Schedule of Investments and cash equivalents are classified as Level 1 assets.

As of September 30, 2024, included in restricted cash was $14.6 million that was held at Deutsche Bank Trust Company Americas in connection with the OSI2 Citibank Facility (as defined in Note 6. Borrowings). Pursuant to the terms of the OSI2 Citibank Facility, the Company was restricted in terms of access to the $14.6 million until the occurrence of the periodic distribution dates and, in connection therewith, the Company’s submission of its required periodic reporting schedules and verifications of the Company’s compliance with the terms of the OSI2 Citibank Facility. As of September 30, 2023, included in restricted cash was $9.1 million that was held at Deutsche Bank Trust Company Americas in connection with the OSI2 Citibank Facility.

Due from Portfolio Companies:

Due from portfolio companies consists of amounts payable to the Company from its portfolio companies, including proceeds from the sale of portfolio companies not yet received or being held in escrow and excluding those amounts attributable to interest, dividends or fees receivable. These amounts are recognized as they become payable to the Company (e.g., principal payments on the scheduled amortization payment date).

Receivables/Payables from Unsettled Transactions:

Receivables/payables from unsettled transactions consist of amounts receivable to or payable by the Company for transactions that have not settled at the reporting date.

Deferred Financing Costs:

Deferred financing costs consist of fees and expenses paid in connection with the closing or amending of credit facilities and debt offerings. Deferred financing costs in connection with credit facilities are capitalized as an asset when incurred. Deferred financing costs in connection with all other debt arrangements are a direct deduction from the related debt liability when incurred. Deferred financing costs are amortized using the effective interest method over the term of the respective debt arrangement. This amortization expense is included in interest expense in the Consolidated Statements of Operations. Upon early termination or modification of a credit facility, all or a portion of unamortized fees related to such facility may be accelerated into interest expense. For extinguishments of the Company’s unsecured notes payable, any unamortized deferred financing costs are deducted from the carrying amount of the debt in determining the gain or loss from the extinguishment.

Deferred Offering Costs:

Legal fees and other costs incurred in connection with the Company’s shelf registration statement are capitalized as deferred offering costs in the Consolidated Statements of Assets and Liabilities. To the extent any such costs relate to equity offerings, these costs are charged as a reduction of capital upon utilization. To the extent any such costs relate to debt offerings, these costs are treated as deferred financing costs and are amortized over the term of the respective debt arrangement. Any deferred offering costs that remain at the expiration of the shelf registration statement or when it becomes probable that an offering will not be completed are expensed.

Income Taxes:

The Company has elected to be subject to tax as a RIC under Subchapter M of the Code and operates in a manner so as to qualify for the tax treatment applicable to RICs. In order to be subject to tax as a RIC, among other things, the Company is required to meet certain source of income and asset diversification requirements and timely distribute dividends to its stockholders of an amount generally at least equal to 90% of investment company taxable income, as defined by the Code and determined without regard to any deduction for dividends paid, for each taxable year. As a RIC, the Company is not subject to U.S. federal income tax on the portion of its taxable income and gains distributed currently to stockholders as a dividend. Depending on the level of taxable income earned during a taxable year, the Company may choose to retain taxable income in excess of current year dividend distributions and would distribute such taxable income in the next taxable year. The Company would then incur a 4% excise tax on such income, as required. To the extent that the Company determines that its estimated current year annual taxable income, determined on a calendar year basis, could exceed estimated current calendar year dividend distributions, the Company accrues excise tax, if any, on estimated excess taxable income as taxable income is earned. The Company anticipates timely distribution of its taxable income within the tax rules under Subchapter M of the Code. For calendar year 2022, the Company incurred $0.1 million of excise tax. The Company didnot incur any U.S. federal excise tax for calendar year 2023. The Company does not expect to incur a U.S. federal excise tax for calendar year 2024.

The Company holds certain portfolio investments through taxable subsidiaries. The purpose of the Company's taxable subsidiaries is to permit the Company to hold equity investments in portfolio companies which are "pass through" entities for U.S. federal income tax purposes in order to comply with the RIC tax requirements. The taxable subsidiaries are consolidated for financial reporting purposes, and portfolio investments held by them are included in the Company’s Consolidated Financial Statements as portfolio investments and recorded at fair value. The taxable subsidiaries are not consolidated with the Company for U.S. federal income tax purposes and may generate income tax expense, or benefit, and the related tax assets and liabilities, as a result of their ownership of certain portfolio investments. This income tax expense, if any, would be reflected in the Company's Consolidated Statements of Operations. The Company uses the liability method to account for its taxable subsidiaries' income taxes. Using this method, the Company recognizes deferred tax assets and liabilities for the estimated future tax effects attributable to temporary differences between financial reporting and tax bases of assets and liabilities. In addition, the Company recognizes deferred tax benefits associated with net operating loss carry forwards that it may use to offset future tax obligations. The Company measures deferred tax assets and liabilities using the enacted tax rates expected to apply to taxable income in the years in which it expects to recover or settle those temporary differences.

FASB ASC Topic 740, Accounting for Uncertainty in Income Taxes ("ASC 740"), provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the Company's Consolidated Financial Statements. ASC 740 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Company's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold are recorded as a tax benefit or expense in the current year. Management's determinations regarding ASC 740 may be subject to review and adjustment at a later date based upon factors including an ongoing analysis of tax laws, regulations and interpretations thereof. The Company recognizes the tax benefits of uncertain tax positions only where the position is "more-likely-than-not" to be sustained assuming examination by tax authorities. Management has analyzed the Company's tax positions and has concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions taken on returns filed for open tax years 2021, 2022 and 2023. The Company identifies its major tax jurisdictions as U.S. Federal and California, and the Company is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change materially in the next 12 months.

Recently Adopted Accounting Pronouncements

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280), which improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments are effective for fiscal years beginning after December 15, 2023 and interim period within fiscal years beginning after December 15, 2024. The Company does not expect this guidance to materially impact its consolidated financial statements.

Note 3. Portfolio Investments

As of September 30, 2024,203.1% of net assets at fair value, or $3.0 billion, was invested in 144 portfolio companies, including (i) $135.2 million in subordinated notes and limited liability company ("LLC") equity interests of Senior Loan Fund JV I, LLC ("SLF JV I"), a joint venture through which the Company and Trinity Universal Insurance Company, a subsidiary of Kemper Corporation ("Kemper"), co-invest in senior secured loans of middle-market companies and other corporate debt securities and (ii) $48.9 million in subordinated notes and LLC equity interests of OCSI Glick JV LLC ("Glick JV" and, together with SLF JV I, the "JVs"), a joint venture through which the Company and GF Equity Funding 2014 LLC ("GF Equity Funding") co-invest primarily in senior secured loans of middle-market companies. As of September 30, 2024,5.3% of net assets at fair value, or $78.5 million, was invested in cash and cash equivalents (including $14.6 million of restricted cash). In comparison, as of September 30, 2023,190.8% of net assets at fair value, or $2.9 billion, was invested in 143 portfolio investments, including (i) $141.5 million in subordinated notes and LLC equity interests of SLF JV I and (ii) $50.0 million in subordinated notes and LLC equity interests of Glick JV. As of September 30, 2023,9.6% of net assets at fair value, or $145.5 million, was invested in cash and cash equivalents (including $9.1 million of restricted cash). As of September 30, 2024,85.2% of the Company's portfolio at fair value consisted of senior secured debt investments and 9.0% consisted of subordinated debt investments, including the debt investments in the JVs. As of September 30, 2023,86.5% of the Company's portfolio at fair value consisted of senior secured debt investments and 7.5% consisted of subordinated debt investments, including the debt investments in the JVs.

The Company also held equity investments in certain of its portfolio companies consisting of common stock, preferred stock, warrants or LLC equity interests. These instruments generally do not produce a current return but are held for potential investment appreciation and capital gain.

During the years ended September 30, 2024, 2023 and 2022, the Company recorded net realized gains (losses) of $(136.4) million, $(33.2) million and $17.2 million, respectively. During the years ended September 30, 2024, 2023 and 2022, the Company recorded net unrealized appreciation (depreciation) of $19.1 million, $(28.6) million and $(136.2) million, respectively.

The composition of the Company's investments as of September 30, 2024 and September 30, 2023 at cost and fair value was as follows:

The following table presents the composition of the Company's debt investments as of September 30, 2024 and September 30, 2023 at floating rates and fixed rates:

The following table presents the financial instruments carried at fair value as of September 30, 2024 on the Company's Consolidated Statement of Assets and Liabilities for each of the three levels of hierarchy established by ASC 820:

(a)In accordance with ASC 820-10, certain investments that are measured using the net asset value per share (or its equivalent) as a practical expedient for fair value have not been classified in the fair value hierarchy. These investments are generally not redeemable. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the Consolidated Statements of Assets and Liabilities.

The following table presents the financial instruments carried at fair value as of September 30, 2023 on the Company's Consolidated Statement of Assets and Liabilities for each of the three levels of hierarchy established by ASC 820:

(a)In accordance with ASC 820-10, certain investments that are measured using the net asset value per share (or its equivalent) as a practical expedient for fair value have not been classified in the fair value hierarchy. These investments are generally not redeemable. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the Consolidated Statements of Assets and Liabilities.

When a determination is made to classify a financial instrument within Level 3 of the valuation hierarchy, the determination is based upon the fact that the unobservable factors are significant to the overall fair value measurement. However, Level 3 financial instruments typically have both unobservable or Level 3 components and observable components (i.e. components that are actively quoted and can be validated by external sources). Accordingly, the appreciation (depreciation) in the tables below includes changes in fair value due in part to observable factors that are part of the valuation methodology. Transfers between levels are recognized at the beginning of the reporting period.

The following table provides a roll-forward in the changes in fair value from September 30, 2023 to September 30, 2024 for all investments for which Oaktree determined fair value using unobservable (Level 3) factors:

(a) There were $38.8 million of transfers into Level 3 from Level 2 for investments during the year ended September 30, 2024 as a result of a change in the number of market quotes available and/or a change in market liquidity.

Changes in Net Assets

The following table presents the changes in net assets for the years ended September 30, 2024, 2023 and 2022:

Distributions

Distributions to common stockholders are recorded on the ex-dividend date. The amount to be paid out as a dividend is determined by the Board of Directors and is based on management’s estimate of the Company’s annual taxable income. Net realized capital gains, if any, may be distributed to stockholders or retained for reinvestment.

The Company has adopted a dividend reinvestment plan (“DRIP”) that provides for reinvestment of any distributions the Company declares in cash on behalf of its stockholders, unless a stockholder elects to receive cash. As a result, if the Company’s Board of Directors declares a cash distribution, then the Company’s stockholders who have not “opted out” of the Company’s DRIP will have their cash distribution automatically reinvested in additional shares of the Company’s common stock, rather than receiving the cash distribution. If the Company’s shares are trading at a premium to net asset value, the Company typically issues new shares to implement the DRIP with such shares issued at the greater of the most recently computed net asset value per share of common stock or 95% of the current market price per share of common stock on the payment date for such distribution. If the Company’s shares are trading at a discount to net asset value, the Company typically purchases shares in the open market in connection with the Company’s obligations under the DRIP.

For income tax purposes, the Company has reported its distributions for the 2023 calendar year as ordinary income. The character of such distributions was appropriately reported to the Internal Revenue Service and stockholders for the 2023 calendar year. To the extent the Company’s taxable earnings for a fiscal and taxable year fall below the amount of distributions paid for the fiscal and taxable year, a portion of the total amount of the Company’s distributions for the fiscal and taxable year is deemed a return of capital for U.S. federal income tax purposes to the Company’s stockholders.

The following table reflects the distributions per share that the Company has paid, including shares issued under the DRIP, on its common stock during the years ended September 30, 2024, 2023 and 2022:

(1) New shares were issued and distributed.

On November 30, 2017, the Company entered into a senior secured revolving credit facility (as amended and restated, the “Syndicated Facility”) pursuant to a Senior Secured Revolving Credit Agreement with the lenders party thereto, ING Capital LLC, as administrative agent, ING Capital LLC, JPMorgan Chase Bank, N.A., BofA Securities, Inc. and MUFG Union Bank, N.A., as joint lead arrangers and joint bookrunners, and JPMorgan Chase Bank, N.A. and Bank of America, N.A., as syndication agents. The Syndicated Facility provides that the Company may use the proceeds of the loans and issuances of letters of credit under the Syndicated Facility for general corporate purposes, including acquiring and funding leveraged loans, mezzanine loans, high-yield securities, convertible securities, preferred stock, common stock and other investments. The Syndicated Facility further allows the Company to request letters of credit from ING Capital LLC, as the issuing bank.

As of September 30, 2024, the size of the Syndicated Facility was $1.218 billion. In addition, pursuant to an "accordion" feature, the Company may increase the size of the facility to up to the greater of $1.25 billion and the Company's net worth, as defined in the facility, under certain circumstances.

As of September 30, 2024, (i) the period during which the Company may make drawings with respect to $1.035 billion of commitments will expire on June 23, 2027 and the maturity date is June 23, 2028, (ii) the period during which the Company may make drawings with respect to the remaining commitments will expire on May 4, 2025 and the maturity date is May 4, 2026 and (iii) the interest rate margin for (a) SOFR loans (which may be 1- or 3-month, at the Company’s option) was 2.00% plus a SOFR adjustment which ranges between 0.11448% and 0.26161% and (b) alternate base rate loans was 1.00%.

The Syndicated Facility is secured by substantially all of the Company’s assets (excluding, among other things, investments held in and by certain subsidiaries of the Company (including OSI 2 Senior Lending SPV, LLC, or “OSI 2 SPV”) or investments in certain portfolio companies of the Company) and guaranteed by certain subsidiaries of the Company.

The Syndicated Facility requires the Company to, among other things, (i) make representations and warranties regarding the collateral as well as each of the Company’s portfolio companies’ businesses, (ii) agree to certain indemnification obligations, and (iii) comply with various affirmative and negative covenants, reporting requirements and other customary requirements for similar revolving credit facilities, including covenants related to: (A) limitations on the incurrence of additional indebtedness and liens, (B) limitations on certain investments, (C) limitations on certain asset transfers and restricted payments, (D) maintaining a certain minimum stockholders’ equity, (E) maintaining a ratio of total assets (less total liabilities) to total indebtedness, of the Company and its subsidiaries (subject to certain exceptions), of not less than 1.50 to 1.00, (F) maintaining a ratio of consolidated EBITDA to consolidated interest expense, of the Company and its subsidiaries (subject to certain exceptions), of not less than 2.25 to 1.00, (G) maintaining a minimum liquidity and net worth, and (H) limitations on the creation or existence of agreements that prohibit liens on certain properties of the Company and certain of its subsidiaries. The Syndicated Facility also includes usual and customary default provisions such as the failure to make timely payments under the facility, the occurrence of a change in control, and the failure by the Company to materially perform under the agreements governing the facility, which, if not complied with, could accelerate repayment under the facility. As of September 30, 2024, the Company was in compliance with all financial covenants under the Syndicated Facility. In addition to the asset coverage ratio described above, borrowings under the Syndicated Facility (and the incurrence of certain other permitted debt) are subject to compliance with a borrowing base that will apply different advance rates to different types of assets in the Company’s portfolio. Each loan or letter of credit originated or assumed under the Syndicated Facility is subject to the satisfaction of certain conditions.

As of each of September 30, 2024 and September 30, 2023, the Company had $430.0 million of borrowings outstanding under the Syndicated Facility, which had a fair value of $430.0 million. The Company's borrowings under the Syndicated Facility bore interest at a weighted average interest rate of 7.443%,6.792% and 2.876% for the years ended September 30, 2024, 2023 and 2022, respectively. For the years ended September 30, 2024, 2023 and 2022, the Company recorded interest expense (inclusive of fees) of $39.4 million, $50.0 million and $19.5 million, respectively, related to the Syndicated Facility.

OSI2 Citibank Facility

On January 23, 2023, as a result of the consummation of the OSI2 Merger, the Company became party to a revolving credit facility (as amended and/or restated from time to time, the “OSI2 Citibank Facility”) with OSI 2 SPV, the Company’s wholly-owned and consolidated subsidiary, as the borrower, the Company, as collateral manager, each of the lenders from time to time party thereto, Citibank, N.A., as administrative agent, and Deutsche Bank Trust Company Americas, as collateral agent.

As of September 30, 2024, the Company was able to borrow up to $400 million under the OSI2 Citibank Facility (subject to borrowing base and other limitations). As of September 30, 2024, the OSI2 Citibank Facility had a reinvestment period through May 25, 2027, during which advances may be made, and matures on January 26, 2029. Following the reinvestment period, OSI 2 SPV will be required to make certain mandatory amortization payments. Borrowings under the OSI2 Citibank Facility bear interest payable quarterly at a rate per year equal to SOFR plus 2.35% per annum. After the reinvestment period, the applicable spread is 3.35% per year. There is also a non-usage fee of 0.50% per year on the unused portion of the OSI2 Citibank Facility, payable quarterly; provided that if the unused portion of the OSI2 Citibank Facility is greater than 30% of the commitments under the OSI2 Citibank Facility, the non-usage fee will be based on an unused portion of 30% of the commitments under the OSI2 Citibank Facility. The OSI2 Citibank Facility is secured by a first priority security interest in substantially all of OSI 2 SPV’s assets. As part of the OSI2 Citibank Facility, OSI 2 SPV is subject to certain limitations as to how borrowed funds may be used and the types of loans that are eligible to be acquired by OSI 2 SPV including restrictions on sector concentrations, loan size, tenor and minimum investment ratings (or estimated ratings). The OSI2 Citibank Facility also contains certain requirements relating to interest coverage, collateral quality and portfolio performance, certain violations of which could result in the acceleration of the amounts due under the OSI2 Citibank Facility.

In connection with the 2027 Notes, the Company entered into an interest rate swap to more closely align the interest rates of its liabilities with its investment portfolio, which consists of predominately floating rate loans. Under the interest rate swap agreement, the Company receives a fixed interest rate of 2.700% and pays a floating interest rate of the three-month SOFR plus

1.658% plus a SOFR adjustment of 0.26161% on a notional amount of $350.0 million. The Company designated the interest rate swap as the hedging instrument in an effective hedge accounting relationship. See Note 12 for more information regarding the interest rate swap.

Note 7. Taxable/Distributable Income and Dividend Distributions

Taxable income differs from net increase (decrease) in net assets resulting from operations primarily due to: (1) unrealized appreciation (depreciation) on investments and foreign currency, as gains and losses are not included in taxable income until they are realized; (2) origination and exit fees received in connection with investments in portfolio companies; (3) organizational costs; (4) income or loss recognition on exited investments; and (5) recognition of interest income on certain loans.

As of September 30, 2024, the Company had net capital loss carryforwards of $696.0 million to offset net capital gains that will not expire, to the extent available and permitted by U.S. federal income tax law, of which $73.0 million are available to offset future short-term capital gains and $623.0 million are available to offset future long-term capital gains. A portion of such net capital loss carryforwards represented a realized loss under sections 382 and 383 of the Code, which is carried forward to future years to offset future gains subject to certain limitations.

Listed below is a reconciliation of "net increase (decrease) in net assets resulting from operations" to taxable income for the years ended September 30, 2024, 2023 and 2022.

(1) The Company's taxable income for the year ended September 30, 2024 is an estimate and will not be finally determined until the Company files its tax return for the fiscal year ending September 30, 2024. Therefore, the final taxable income may be different than the estimate.

The Company uses the liability method to account for its taxable subsidiaries' income taxes. Using this method, the Company recognizes deferred tax assets and liabilities for the estimated future tax effects attributable to temporary differences between financial reporting and tax bases of assets and liabilities. In addition, the Company recognizes deferred tax benefits associated with net loss carry forwards that it may use to offset future tax obligations. The Company measures deferred tax assets and liabilities using the enacted tax rates expected to apply to taxable income in the years in which it expects to recover or settle those temporary differences.

When assessing the realizability of deferred tax assets, the Company considers whether it is probable that some or all of the deferred tax assets will not be realized. In determining whether the deferred tax assets are realizable, the Company considers the period of expiration of the tax asset, historical and projected taxable income and tax liabilities for the tax jurisdiction in which the tax asset is located. The deferred tax asset recognized by the Company, as it relates to the higher tax basis in the carrying value of certain assets compared to the book basis of those assets, will be recognized in future years by these taxable entities. Deferred tax assets are based on the amount of the tax benefit that the Company’s management has determined is more likely than not to be realized in future periods. In determining the realizability of this tax benefit, management considered numerous factors that will give rise to pre-tax income in future periods. Among these are the historical and expected future book and tax basis pre-tax income of the Company and unrealized gains in the Company’s assets at the determination date. Based on these and other factors, the Company determined that, as of September 30, 2024, $8.7 million of the $8.7 million deferred tax assets would not more likely than not be realized in future periods.

For the year ended September 30, 2024, the Company recognized a total benefit for income tax related to realized and unrealized gains (losses) of $0.1 million, which was composed primarily of a current income tax benefit. For the year ended September 30, 2023, the Company recognized a total expense for income tax related to realized and unrealized gains (losses) of $1.7 million, which was composed primarily of a deferred income tax expense. For the year ended September 30, 2022, the Company recognized a provision for income tax related to net investment income of $3.3 million, which was all current income tax expense. For the year ended September 30, 2022, the Company also recognized a total provision for income tax related to realized and unrealized gains (losses) of $0.3 million, which was composed of (i) a current income tax expense of approximately $1.3 million and (ii) a deferred income tax benefit of approximately $1.0 million, which resulted from unrealized depreciation on investments held by the Company’s wholly-owned taxable subsidiaries.

As of September 30, 2024, the Company's last tax year end, the components of accumulated overdistributed earnings on a tax basis were as follows:

The aggregate cost of investments for U.S. federal income tax purposes was $3,153.0 million as of September 30, 2024. As of September 30, 2024, the aggregate gross unrealized appreciation for all investments in which there was an excess of value over cost for U.S. federal income tax purposes was $674.5 million. As of September 30, 2024, the aggregate gross unrealized depreciation for all investments in which there was an excess of cost for U.S. federal income tax purposes over value was $812.5 million. Net unrealized depreciation based on the aggregate cost of investments for U.S. federal income tax purposes was $138.0 million.

Note 8. Realized Gains or Losses and Net Unrealized Appreciation or Depreciation

Realized Gains or Losses

Realized gains or losses are measured by the difference between the net proceeds from the sale or redemption and the cost basis of the investment without regard to unrealized appreciation or depreciation previously recognized, and include investments written-off during the period, net of recoveries. Realized losses may also be recorded in connection with the Company's determination that certain investments are considered worthless securities and/or meet the conditions for loss recognition per the applicable tax rules.

During the year ended September 30, 2024, the Company recorded an aggregate net realized loss of $136.4 million, which consisted of the following:

(1) This investment was denominated in foreign currency and the realized gain (loss) shown in this table includes gains (losses) due to foreign currency translation, which was offset by gains (losses) on foreign currency forward contracts.

During the year ended September 30, 2023, the Company recorded an aggregate net realized loss of $33.2 million, which consisted of the following:

During the year ended September 30, 2022, the Company recorded an aggregate net realized gain of $17.2 million, which consisted of the following:

Net Unrealized Appreciation or Depreciation

Net unrealized appreciation or depreciation reflects the net change in the valuation of the portfolio pursuant to the Company's valuation guidelines and the reclassification of any prior period unrealized appreciation or depreciation.

During the years ended September 30, 2024, 2023 and 2022, the Company recorded net unrealized appreciation (depreciation) of $19.1 million, $(28.6) million and $(136.2) million, respectively. For the year ended September 30, 2024, this consisted of $69.8 million of net unrealized appreciation related to exited investments (a portion of which resulted in a reclassification to realized losses), partially offset by $37.5 million of net unrealized depreciation on equity investments, $8.8 million of net unrealized depreciation of foreign currency forward contracts and $4.4 million of net unrealized depreciation on debt investments. For the year ended September 30, 2023, this consisted of $49.1 million of net unrealized depreciation on debt investments and $4.9 million of net unrealized depreciation on equity investments, partially offset by $25.4 million of net unrealized appreciation related to exited investments (a portion of which resulted in a reclassification to realized losses) and $0.1 million of net unrealized appreciation of foreign currency forward contracts. For the year ended September 30, 2022, this consisted of $94.1 million of net unrealized depreciation on debt investments, $35.4 million of net unrealized depreciation on equity investments and $11.7 million of net unrealized depreciation related to exited investments (a portion of which resulted in a reclassification to realized gains), partially offset by $4.9 million of net unrealized appreciation of foreign currency forward contracts.

Note 9. Concentration of Credit Risks

The Company deposits its cash with financial institutions and at times such balances are in excess of the FDIC insurance limit. The Company limits its exposure to credit loss by depositing its cash with high credit quality financial institutions and monitoring their financial stability.

Note 10. Related Party Transactions

As of September 30, 2024 and September 30, 2023, the Company had a liability on its Consolidated Statements of Assets and Liabilities in the amount of $15.5 million and $19.5 million, respectively, reflecting the unpaid portion of the base management fees and incentive fees payable to Oaktree.

Investment Advisory Agreement

The Company is party to the Investment Advisory Agreement. Under the Investment Advisory Agreement, the Company pays Oaktree a fee for its services under the Investment Advisory Agreement consisting oftwo components: a base management fee and an incentive fee. The cost of both the base management fee payable to Oaktree and any incentive fees earned by Oaktree is ultimately borne by common stockholders of the Company.

The investment advisory agreement with Oaktree was amended and restated on March 19, 2021 in connection with the closing of the OCSI Merger, on January 23, 2023 in connection with the closing of OSI2 Merger and on November 14, 2024 to reflect a reduced base management fee. The term “Investment Advisory Agreement” refers collectively to the agreements with Oaktree.

Unless earlier terminated as described below, the Investment Advisory Agreement will remain in effect from year-to-year if approved annually by the Board of Directors of the Company or by the affirmative vote of the holders of a majority of the Company’s outstanding voting securities, including, in either case, approval by a majority of the directors of the Company who are not interested persons. The Investment Advisory Agreement will automatically terminate in the event of its assignment. The Investment Advisory Agreement may be terminated by either party without penalty upon 60 days’ written notice to the other. The Investment Advisory Agreement may also be terminated, without penalty, upon the vote of a majority of the outstanding voting securities of the Company.

Base Management Fee

Effective as of July 1, 2024, the base management fee is calculated at an annual rate of 1.00% of total gross assets, including any investment made with borrowings, but excluding cash and cash equivalents; provided, however, that for the period from July 1, 2024 to January 23, 2025, the base management fee shall be calculated at such an annual rate as to cause (1) the base management fee less (2) previously agreed waivers of $750,000 of base management fees per quarter (with such amount appropriately prorated for any partial quarter) to equal 1.00% of the Company’s gross assets, including any investments made with borrowings, but excluding any cash and cash equivalents. The base management fee is payable quarterly in arrears and the fee for any partial month or quarter is appropriately prorated. From May 3, 2019 through June 30, 2024, the base management fee was 1.50% of total gross assets, including any investments made with borrowings, but excluding any cash and cash equivalents, provided that the base management fee on gross assets that exceeded the product of (A)200% and (B) the Company’s net asset value was 1.00%. The 200% was calculated in accordance with the Investment Company Act. In connection with the OCSI Merger, Oaktree waived an aggregate of $6 million of base management fees otherwise payable to Oaktree in thetwo years following the closing of the OCSI Merger on March 19, 2021 at a rate of $750,000 per quarter (with such amount appropriately prorated for any partial quarter). In connection with the OSI2 Merger, Oaktree waived an aggregate of $9.0 million of base management fees payable to Oaktree as follows: $6.0 million at a rate of $1.5 million per quarter (with such amount appropriately prorated for any partial quarter) in the first year following closing of the OSI2 Merger on January 23, 2023 and $3.0 million at a rate of $750,000 per quarter (with such amount appropriately prorated for any partial quarter) in the second year following closing of the OSI2 Merger. Oaktree also waived additional base management fees such that the total amount of waived base management fees (including those waived in connection with the OSI2 Merger described above) was $1.5 million for each of the three months ended March 31, 2024 and June 30, 2024.

For the years ended September 30, 2024, 2023 and 2022, the base management fee incurred under the Investment Advisory Agreement was $38.2 million (net of waiver), $39.4 million (net of waiver) and $36.6 million (net of waiver), respectively.

Incentive Fee

The incentive fee consists of two parts. Under the Investment Advisory Agreement, the first part of the incentive fee (the “incentive fee on income” or "Part I incentive fee") is calculated and payable quarterly in arrears based upon the “pre-incentive fee net investment income” of the Company for the immediately preceding quarter. The payment of the incentive fee on income is subject to payment of a preferred return to investors each quarter (i.e., a “hurdle rate”), expressed as a rate of return on the value of the Company’s net assets at the end of the most recently completed quarter, of 1.50%, subject to a “catch up” feature.

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, structuring, diligence and consulting fees or other fees that the Company receives from portfolio companies, other than fees for providing managerial assistance) accrued during the fiscal quarter, minus the Company’s operating expenses for the quarter (including the base management fee, expenses payable under the Administration Agreement and any interest expense and dividends paid on any issued and outstanding preferred stock, but excluding the incentive fee). Pre-incentive fee net investment income includes, in the case of investments with a deferred interest feature (such as OID debt, instruments with PIK interest and zero coupon securities), accrued income that the Company has not yet received in cash. Pre-incentive fee net investment income does not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation. In addition, pre-incentive fee net investment income does not include any amortization or accretion of any purchase premium or purchase discount to interest income resulting solely from merger-related accounting adjustments in connection with the assets acquired in the OCSI Merger or in the OSI2 Merger, in each case, including any premium or discount paid for the acquisition of such assets, solely to the extent that the inclusion of such merger-related accounting adjustments, in the aggregate, would result in an increase in pre-incentive fee net investment income.

Under the Investment Advisory Agreement, the calculation of the incentive fee on income for each quarter is as follows:

•No incentive fee is payable to Oaktree in any quarter in which the Company’s pre-incentive fee net investment income does not exceed the preferred return rate of 1.50% (the “preferred return”) on net assets;

•100% of the Company’s pre-incentive fee net investment income, if any, that exceeds the preferred return but is less than or equal to 1.8182% in any fiscal quarter is payable to Oaktree. This portion of the incentive fee on income is referred to as the “catch-up” provision, and it is intended to provide Oaktree with an incentive fee of 17.5% on all of the Company’s pre-incentive fee net investment income when the Company’s pre-incentive fee net investment income exceeds 1.8182% on net assets in any fiscal quarter; and

•For any quarter in which the Company’s pre-incentive fee net investment income exceeds 1.8182% on net assets, the incentive fee on income is equal to 17.5% of the amount of the Company’s pre-incentive fee net investment income, as the preferred return and catch-up will have been achieved.

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. For the year ended September 30, 2024, Oaktree waived $4.4 million of Part I incentive fees.

For the years ended September 30, 2024, 2023 and 2022, the first part of the incentive fee (incentive fee on income) incurred under the Investment Advisory Agreement was $30.3 million (net of waiver), $35.8 million and $26.6 million, respectively.

Under the Investment Advisory Agreement, the second part of the incentive fee (the "capital gains incentive fee") is determined and payable in arrears as of the end of each fiscal year (or upon termination of the Investment Advisory Agreement, as of the termination date) commencing with the fiscal year ended September 30, 2019 and equals 17.5% of the Company’s realized capital gains, if any, on a cumulative basis from the beginning of the fiscal year ended September 30, 2019 through the end of each subsequent fiscal year, 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 under the Investment Advisory Agreement. Any realized capital gains, realized capital losses, unrealized capital appreciation and unrealized capital depreciation with respect to the Company’s portfolio as of the end of the fiscal year ended September 30, 2018 are excluded from the calculations of the second part of the incentive fee. In addition, the calculation of realized capital gains, realized capital losses and unrealized capital depreciation does (1) not include any such amounts resulting solely from merger-related accounting adjustments in connection with the assets acquired in the OCSI Merger or in the OSI2 Merger, in each case, including any premium or discount paid for the acquisition of such assets, solely to the extent that the inclusion of such merger-related accounting adjustments, in the aggregate, would result in an increase in the capital gains incentive fee, (2) include any such amounts associated with the investments acquired in the OCSI Merger for the period from October 1, 2018 to the date of closing of the OCSI Merger, solely to the extent that the exclusion of such amounts, in the aggregate, would result in an increase in the capital gains incentive fee and (3) include any such amounts associated with the investments acquired in the OSI2 Merger for the period from August 6, 2018 to the date of closing of the OSI2 Merger, solely to the extent that the exclusion of such amounts, in the aggregate, would result in an increase in the capital gains incentive fee. As of September 30, 2024, the Company paid $9.6 million of capital gains incentive fees cumulatively under the Investment Advisory Agreement (net of waivers). For the years ended September 30, 2024, 2023 and 2022, the Company did not incur any capital gains incentive fees.

GAAP requires that the capital gains incentive fee accrual consider the cumulative aggregate unrealized capital appreciation in the calculation, as a capital gains incentive fee would be payable if such unrealized capital appreciation were realized on a theoretical "liquidation basis." A fee so calculated and accrued would not be payable under applicable law and may never be paid based upon the computation of capital gains incentive fees in subsequent periods. Amounts ultimately paid under the Investment Advisory Agreement will be consistent with the formula reflected in the Investment Advisory Agreement. This GAAP accrual is calculated using the aggregate cumulative realized capital gains and losses and aggregate cumulative unrealized capital depreciation included in the calculation of the capital gains incentive fee plus the aggregate cumulative unrealized capital appreciation. Any realized capital gains and losses and cumulative unrealized capital appreciation and depreciation with respect to the Company’s portfolio as of the end of the fiscal year ended September 30, 2018 are excluded from the GAAP accrual. If such amount is positive at the end of a period, then GAAP requires the Company to record a capital gains incentive fee equal to 17.5% of such cumulative amount, less the aggregate amount of actual capital gains incentive fees payable or capital gains incentive fees accrued under GAAP in all prior periods. The resulting accrual for any capital gains incentive fee under GAAP in a given period may result in an additional expense if such cumulative amount is greater than in the prior period or a reversal of previously recorded expense if such cumulative amount is less than in the prior period. If such cumulative amount is negative, then there is no accrual. There can be no assurance that such unrealized capital appreciation will be realized in the future or any accrued capital gains incentive fee will become payable under the Investment Advisory Agreement. For the years ended September 30, 2024 and 2023, there wereno accrued capital gains incentive fees. For the year ended September 30, 2022, $8.8 million of previously accrued capital gains incentive fees were reversed. As of September 30, 2024, the total accrued capital gains incentive fee liability was zero.
