Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Basis of Presentation: The accompanying 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-Q and Regulation S-X. In the opinion of management, all adjustments of a normal recurring nature considered necessary for the fair presentation of the consolidated financial statements have been made. The Company is an investment company following the accounting and reporting guidance in FASB ASC Topic 946, Financial Services - Investment Companies ("ASC 946"). Use of Estimates: The preparation of the consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions affecting amounts reported in the consolidated 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 the Company and its consolidated subsidiary. The consolidated subsidiary is wholly-owned and, as such, consolidated into the consolidated financial statements. As an investment company, portfolio investments held by the Company are not consolidated into the consolidated financial statements but rather are included on the Consolidated Statements of Assets and Liabilities as investments at fair value. Fair Value Measurements: The Adviser, as the valuation designee of the Board pursuant to Rule 2a-5 under the Investment Company Act, determines the fair value of our assets on at least a quarterly basis in accordance with ASC Topic 820, Fair Value Measurements and Disclosures ("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 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 the Adviser'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. The Adviser'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, the Adviser 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. The Adviser seeks to obtain at least two quotations for the subject or similar securities, typically from pricing vendors. If the Adviser is unable to obtain two quotes from pricing vendors, or if the prices obtained from pricing vendors are not within the Adviser's set threshold, the Adviser seeks to obtain a quote directly from a broker making a market for the asset. The Adviser 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. The Adviser 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, the Adviser performs due diligence procedures over pricing vendors to understand their methodology and controls to support their use in the valuation process. Generally, the Adviser does not adjust any of the prices received from these sources. If the quotations obtained from pricing vendors or brokers are determined not to be reliable or are not readily available, the Adviser 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, the Adviser 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. The Adviser 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. The Adviser 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 the Adviser 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, the Adviser 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. The Board has designated the Adviser to serve as its valuation designee under Rule 2a-5 under the Investment Company Act. The Adviser 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 the Adviser's valuation team; •Preliminary valuations are then reviewed and discussed with management of the Adviser; •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 the Adviser; •The Adviser 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 the Adviser, and the Adviser responds and supplements the valuation report to reflect any discussions between the Adviser and the Audit Committee; and •The Adviser, 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 March 31, 2025 and September 30, 2024 was determined by the Adviser, as the Board's valuation designee. The Company has and will continue to engage independent valuation firms to provide assistance each quarter 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. 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," "other assets," "secured borrowings" and "credit facility payable," which are reported at amortized cost, all assets and liabilities on the Consolidated Statements of Assets and Liabilities approximate fair value. The carrying value of the line items titled "interest receivable," "accounts payable, accrued expenses and other liabilities," "base management fee payable," "due to affiliates," "interest payable" and "director fees payable" 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. Secured Borrowings: Securities sold and simultaneously repurchased at a premium are reported as financing transactions in accordance with FASB ASC Topic 860, Transfers and Servicing ("ASC 860"). Amounts payable to the counterparty are due on the repurchase settlement date and, excluding accrued interest, such amounts are presented in the accompanying Consolidated Statements of Assets and Liabilities as secured borrowings. Premiums payable are separately reported as accrued interest. 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 March 31, 2025 and September 30, 2024, there were no investments on non-accrual status. For the Company's secured borrowings, the interest earned on the entire loan balance is recorded within interest income and the interest earned by the counterparty is recorded within interest expense in the Consolidated Statements of Operations. PIK Interest Income The Company's investments in debt securities may contain payment-in-kind ("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 bases of these investments in the consolidated financial statements including for purposes of computing the capital gains incentive fee payable by the Company to the Adviser. To maintain its status as a RIC, certain income from PIK interest may be required to be distributed (or deemed distributed) to the Company’s unitholders, even though the Company has not yet collected the cash and may never do so. Fee Income The Adviser or its affiliates may provide financial advisory services to portfolio companies in connection with structuring a transaction 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: 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 with financial institutions and, at times, cash held in bank accounts may exceed 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. Deferred Financing Costs: Deferred financing costs consist of fees and expenses paid in connection with the closing or amending of credit facilities. Deferred financing costs incurred in connection with credit facilities are capitalized as an asset when incurred. Deferred financing costs incurred 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. Organization and Offering Costs: Costs associated with the organization of the Company are expensed as incurred. Costs associated with the offering of the units are capitalized as "deferred offering costs" on the Consolidated Statements of Assets and Liabilities and amortized over a 12-month period from incurrence. For the three and six months ended March 31, 2025, the Company did not incur any organization costs. For the three and six months ended March 31, 2024, the Company incurred organization costs of zero and $5, respectively. For each of the three and six months ended March 31, 2025, the Company amortized offering costs of $0. For the three and six months ended March 31, 2024, the Company amortized offering costs of $87 and $174, respectively. Income Taxes: The Company has elected to be treated as a RIC under Subchapter M of the Code. So long as the Company maintains its status as a RIC, it generally will not pay corporate-level U.S. federal income taxes on any ordinary income or capital gains that it timely distributes (or, is deemed to distribute, except with respect to certain retained capital gains, as discussed below) at least annually to its unitholders as dividends. Rather, any tax liability related to income earned and timely distributed (or deemed timely distributed) by the Company would represent obligations of the Company’s investors and would not be reflected in the consolidated financial statements of the Company. Any net operating losses, foreign tax credits and most other tax attributes generally will not pass through to the Company's investors. The Company will be subject to corporate-level U.S. federal income tax on any undistributed income and/or gains. To qualify for and maintain qualification as a RIC, the Company must, among other things, meet certain source-of-income and asset diversification requirements. In addition, to qualify for RIC tax treatment, the Company must distribute to its unitholders, for each taxable year, at least 90% of its “investment company taxable income” (as defined in the Code) for that year, which is generally its ordinary income plus the excess, if any, of its realized net short-term capital gains over its realized net long-term capital losses. In addition, based on the excise tax distribution requirements, the Company is subject to a 4% nondeductible federal excise tax on undistributed income unless the Company distributes in a timely manner in each taxable year an amount at least equal to the sum of (1) 98% of its ordinary income for the 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 prior years. 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. The Company did not incur any U.S. federal excise tax for calendar years 2024 and 2023. The Company does not expect to incur a U.S. federal excise tax for calendar year 2025. The Company evaluates tax positions taken or expected to be taken in the course of preparing its consolidated financial statements to determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax positions not deemed to meet the “more-likely-than-not” threshold are reserved and recorded as a tax benefit or expense in the current year. All penalties and interest associated with income taxes are included in income tax expense. Conclusions regarding tax positions are subject to review and may be adjusted at a later date based on factors including, but not limited to, on-going analyses of tax laws, regulations and interpretations thereof. 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 year 2023. 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.
