[1] The total principal amount is presented for debt investments while the number of shares or units owned is presented for equity investments. Equity investments are non-income producing securities, unless otherwise noted. Ownership of certain equity investments occurs through a holding company or partnership. The fair values of investments were valued using significant unobservable inputs, unless otherwise noted. See Note 5. Fair Value Measurements. The investment is treated as a non-qualifying asset under Section 55(a) of the Investment Company Act of 1940, as amended (the “1940 Act”). Under the 1940 Act, the Company cannot acquire any non-qualifying asset unless, at the time the acquisition is made, qualifying assets represent at least 70% of the Company’s total assets. As of September 30, 2023, total non-qualifying assets at fair value represented 16.0% of the Company’s total assets calculated in accordance with the 1940 Act. The majority of the investments bear interest at a rate that is permitted to be determined by reference to the Secured Overnight Financing Rate (“SOFR” or “SF”), Euro Interbank Offered Rate (“EURIBOR” or “E”), Canadian Bankers Acceptance Rate (“CDOR” or “C”), Australian Interbank Rate (“AUD” or “A”), Sterling Overnight Index Average (“SONIA” or “SN”) or the London Interbank Offered Rate (“LIBOR” or “L”) denominated in U.S. dollars which reset daily, monthly, quarterly, semiannually or annually. For each, the Company has provided the spread over the applicable index and the weighted average current interest rate in effect as of September 30, 2023. Certain investments are subject to an interest rate floor. For fixed rate loans, a spread above a reference rate is not applicable. For positions with multiple outstanding contracts, the spread for the largest outstanding contract is shown. Listed below are the index rates as of September 30, 2023, which was the last business day of the period on which the applicable index rates were determined. The actual index rate for each loan listed may not be the applicable index rate outstanding as of September 30, 2023, as the loan may have priced or repriced based on an index rate prior to September 30, 2023. For positions with multiple interest rate contracts, the interest rate shown is a weighted average current interest rate in effect as of September 30, 2023. Denotes that all or a portion of the contract was indexed to the 180-day LIBOR, which was last quoted on June 30, 2023 at 5.76% . The headquarters of this portfolio company is located in Luxembourg. Denotes that all or a portion of the contract was indexed to the 90-day Term SOFR which was 5.40% as of September 30, 2023. The fair value of this investment was valued using Level 2 inputs. See Note 5. Fair Value Measurements. All or a portion of the loan interest was capitalized into the outstanding principal balance of the loan in accordance with the terms of the credit agreement during the period from June 30, 2023 (commencement of operations) to September 30, 2023. Denotes that all or a portion of the contract was indexed to the 30-day Term SOFR which was 5.32% as of September 30, 2023. Denotes that all or a portion of the contract was indexed to the 180-day EURIBOR, which was 4.13% as of September 30, 2023. Denotes that all or a portion of the contract was indexed to the 90-day EURIBOR, which was 3.95% as of September 30, 2023. Investment is denominated in foreign currency and is translated into U.S. dollars as of the valuation date or the date of the transaction. See Note 2. Significant Accounting Policies and Recent Accounting Updates - Foreign Currency Translation.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Note 1. Organization GCP SG Warehouse 2022-1 (“GCP SG Warehouse” or the “Fund”) was organized in the state of Delaware on December 9, 2022 as a Delaware statutory trust for the purpose of making investments primarily through direct lending to U.S. private companies in the middle market in the form of one stop and other senior secured loans. On June 8, 2023, the Fund entered into a credit agreement (the “GCP Warehouse Credit Facility”) by and among the Fund, as borrower, Société Générale, as administrative agent, the lenders and the subordinated noteholders party thereto, and Wilmington Trust, National Association as collateral agent, collateral administrator, custodian and collateral custodian. In connection with entering into the GCP Warehouse Credit Facility, the Fund’s trust agreement was amended and restated (the “Amended Trust Agreement”) and the Fund commenced operations. The Fund is beneficially owned by GCP HS Fund, a Delaware statutory trust, and GCP CLO Holdings Sub LP (“GCP CLO Sub”), an exempted limited partnership registered in the Cayman Islands (together the “Beneficial Owners”). GC Investment Management LLC (the “Investment Manager”) serves as the investment manager of GCP HS Fund. GC Investment Management LLC is a relying adviser of GC OPAL Advisors LLC, which is a registered investment adviser with the Securities and Exchange Commission.	Note 1. Organization Golub Capital Private Credit Fund (“GCRED” or the “Company”), is a Delaware statutory trust formed on May 13, 2022. The Company is an externally managed, non-diversified, closed-end management investment company that has elected to be regulated as a business development company (“BDC”) under the Investment Company Act of 1940, as amended (the “1940 Act”). In addition, for U.S. federal income tax purposes, beginning with its tax year ended September 30, 2023, the Company intends to elect to be treated as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). The Company commenced operations on June 30, 2023. The Company’s fiscal year end is September 30. The Company’s investment objective is to generate current income and capital appreciation by investing primarily in privately originated and privately negotiated investments, predominantly through direct lending to U.S. private companies in the middle-market and upper middle-market in the form of one stop and other senior secured loans. The Company may selectively invest in second lien and subordinated loans (including loans that rank senior only to a borrower’s equity securities and ranks junior to all of such borrower’s other indebtedness in priority of payment) of private companies. The Company may also invest in liquid credit instruments, including secured floating rate syndicated loans, securitized products and corporate bonds, and the Company’s portfolio may, but will not necessarily, initially be comprised of a greater percentage of such instruments than it will as the Company’s investment program matures, though the exact allocation may vary from time to time depending on market conditions and available investment opportunities. The Company’s portfolio may also include equity interests such as preferred equity, debt investments accompanied by equity-related securities (including warrants) and, to a limited extent, common equity investments, which generally would be obtained as part of providing a broader financing solution. The Company has entered into an investment advisory agreement (the “Investment Advisory Agreement”) with GC Advisors, LLC (the “Investment Adviser”), under which the Investment Adviser manages the day-to-day operations of, and provides investment advisory services to, the Company. Under an administration agreement (the “Administration Agreement”) the Company is provided with certain services by an administrator, which is currently Golub Capital LLC (the “Administrator”). The Company offers on a continuous basis up to $5.0 billion of common shares of beneficial interest pursuant to an offering registered with the Securities and Exchange Commission (the “SEC”). The Company has applied for exemptive relief from the SEC that, if granted, will permit the Company to offer to sell any combination of three classes of common shares, Class S shares, Class D shares and Class I shares, with a dollar value up to the maximum offering amount (the “Public Offering”). There is no assurance, however, that the relief will be granted. Beginning in April 2023, the Company commenced a separate private offering of Class F shares (the “Private Offering”) to certain accredited investors (the “Private Offering Investors”). On June 14, 2023, the Company completed the Private Offering and entered into subscription agreements with the Private Offering Investors for total commitments of $650.3 million to purchase the Company’s Class F shares. The offer and sale of these Class F Shares was exempt from the registration provisions of the Securities Act of 1933, as amended, pursuant to Section 4(a)(2) and/or Regulation S thereunder. Following the completion of the Private Offering, the Company’s Class F Shares were reclassified as Class I Shares (the “Reclassification”). On June 30, 2023, the Company received the Private Offering subscription proceeds and issued 26,010,927.600 shares of the Company’s Class F common shares (reclassified as Class I shares) at a purchase price of $25.00 per share. On July 1, 2023, the Company entered into a Share Purchase and Sale Agreement (the “Share Purchase and Sale Agreement”), by and among the Company, GCP HS Fund, GCP CLO Holdings Sub LP (each, a “Seller” and, collectively, “Sellers”), and the Investment Adviser. Pursuant to the Share Purchase and Sale Agreement, the Company acquired all of the assets and liabilities (the “Seed Assets”) of GCP SG Warehouse 2022-1 (the “CLO Vehicle”) through the purchase from the Sellers of 100% of the beneficial interests in, and 100% of the subordinated notes issued by the CLO Vehicle.

Accounting Policies [Abstract]
Accounting Policies and Recent Accounting Updates	Note 2. Accounting Policies and Recent Accounting Updates Basis of presentation: Financial Services Investment Companies. Fair value of financial instruments: Fair Value Measurement . Use of estimates: Restricted cash and cash equivalents: Foreign currency translation: (1) restricted cash and cash equivalents, investments at fair value, interest receivable, debt, interest payable and other assets and payables - at the spot exchange rate on the last business day of the period; and (2) purchases and sales of investments, borrowings and payments of debt, income and expenses - at the exchange rates prevailing on the respective dates of such transactions. Net assets and fair values are presented based on the applicable foreign exchange rates described above and fluctuations arising from the translation of assets and liabilities are included with the net change in unrealized appreciation (depreciation) on translation of assets and liabilities in foreign currencies on the Statement of Operations. Realized gains or losses arising from foreign currency transactions are reported as components of the net realized gain (loss) on foreign currency transactions on the Statement of Operations. ​ Note 2. Accounting Policies and Recent Accounting Updates (continued) Foreign security and currency transactions involve certain considerations and risks not typically associated with investing in U.S. companies. These risks include, but are not limited to, currency fluctuations and revaluations and future adverse political, social and economic developments, which could cause investments in foreign markets to be less liquid and prices more volatile than those of comparable U.S. companies or U.S. government securities. Revenue recognition: Investments and related investment income: For investments with contractual payment-in-kind (“PIK”) interest, contractual interest is accrued, added to the principal balance and generally becomes due at maturity. For the period from June 8, 2023 (commencement of operations) to June 30, 2023, the Fund capitalized PIK interest of $205,621 into the principal balance of certain debt investments. Realized gains or losses on investments are measured by the difference between the net proceeds from the disposition and the amortized cost basis of investment, without regard to unrealized gains or losses previously recognized. The Fund reports the changes in fair value of investments that are measured at fair value as a component of the net change in unrealized appreciation (depreciation) on investments on the Statement of Operations. Non-accrual loans: Interest payments received on non-accrual loans are recognized as income or applied to principal depending upon management’s judgment. When the Fund receives principal payments on a non-accrual loan in an amount that exceeds the loan’s amortized cost, it may recognize the excess principal payment as interest income based on upon management’s judgement. Non-accrual loans are restored to accrual status when past due principal and interest is paid, and, in management’s judgment, payments are likely to remain current. As of June 30, 2023, the Fund had no portfolio company investments on non-accrual status. Income taxes: Income Taxes Deferred debt issuance costs:

Net Assets	Note 3. Net Assets As of June 30, 2023, the Fund was beneficially owned 98% by GCP HS Fund and 2% by GCP CLO Sub. Profits and losses are allocated to the Beneficial Owners in proportion to their respective beneficial ownership percentage.	Note 10. Net Assets Share Issuances On April 27, 2023, an affiliate of the Investment Adviser purchased 2,000 shares of the Company’s Class F common shares (reclassified as Class I shares) at a purchase price of $25.00 per share. On June 14, 2023, the Company completed the Private Offering and entered into subscription agreements with the Private Offering Investors for total commitments of $650.3 million to purchase the Company’s Class F common shares. Following the completion of the Private Offering and prior to the commencement of the Public Offering, the Company’s Class F shares were reclassified as Class I shares. On June 30, 2023, the Company received the Private Offering subscription proceeds and issued 26,010,927.600 Class F common shares (reclassified as Class I shares) at a purchase price of $25.00 per share. In connection with its formation, the Company has the authority to issue an unlimited number of common shares of beneficial interest at $0.01 per share par value. The Company offers on a continuous basis up to $5.0 billion of common shares of beneficial interest pursuant to the Public Offering. The Company has applied for exemptive relief from the SEC that, if granted, will permit the Company to offer to sell any combination of three classes of common shares, Class S shares, Class D shares and Class I shares, through the Public Offering with a dollar value up to the maximum offering amount. There is no assurance, however, that the relief will be granted. The Company will accept purchase orders and hold investors’ funds in an interest-bearing escrow account until the Company receives purchase orders for at least 100 investors in such class and the Company’s Board has authorized the release of the funds in the escrow account. The share classes have different ongoing distribution and/or shareholder servicing fees. In connection with the Public Offering, the Company sells shares at an offering price per share as determined in accordance with a share pricing policy. Under such policy, in connection with each monthly closing on the sale of shares of Class S shares, Class D shares and Class I shares, the Board has authorized the Investment Adviser to establish a net offering price that it believes reflects a price per share that is no less than the then-current NAV per share. The following table summarizes the net offering price per share of Class I shares during the period from June 30, 2023 (commencement of operations) to September 30, 2023: ​ ​ ​ ​ ​ ​ Net Offering Price Per Share For the Month Ended ​ Class I July 31, 2023 ​ $ 25.00 August 31, 2023 ​ 25.05 September 30, 2023 ​ 25.00 ​ Distributions and Distribution Reinvestment The Board authorizes and declares monthly distribution amounts per share that are recorded by the Company on the record date.

Share Repurchase Program At the discretion of the Board, the Company intends to commence a share repurchase program in which the Company intends to repurchase, in each quarter, up to 5% of the NAV of the Company’s common shares outstanding as of the close of the previous calendar quarter. The Board may amend, suspend or terminate the share repurchase program if it deems such action to be in the best interest of shareholders. As a result, share repurchases may not be available each quarter. The Company intends to conduct such repurchase offers in accordance with the requirements of Rule 13e-4 promulgated under the Securities Exchange Act of 1934, as amended, and the 1940 Act. All shares purchased pursuant to the terms of each tender offer will be retired and thereafter will be authorized and unissued shares. Under the share repurchase program, to the extent the Company offers to repurchase shares in any particular quarter, it is expected to repurchase shares pursuant to tender offers on or around the last business day of the first month of such quarter using a purchase price equal to the NAV per share as of the last calendar day of the prior quarter, except that shares that have not been outstanding for at least one year will be repurchased at 98% of such NAV (an “Early Repurchase Deduction”). The one-year holding period is measured as of the subscription closing date immediately following the prospective repurchase date. The Early Repurchase Deduction will be retained by the Company for the benefit of remaining shareholders. During the period from June 30, 2023 (commencement of operations) to September 30, 2023, the Company did not repurchase any shares.

Under the terms of the collateral management agreement between the Investment Manager and the Fund (“GCP Warehouse Collateral Management Agreement”), the Investment Manager is entitled to receive an annual fee in an amount equal to 0.25% of the principal balance of the portfolio of loans held by the Fund at the beginning of the collection period relating to each payment date, which is payable quarterly in arrears unless waived or deferred by the Investment Manager. For the period from June 8, 2023 (commencement of operations) to June 30, 2023, the Investment Manager irrevocably waived $130,519 of collateral management fees payable under the GCP Warehouse Collateral Management Agreement. During the period from June 8, 2023 (commencement of operations) to June 30, 2023, the Fund purchased investments from entities managed by the Investment Manager, or an affiliate of the Investment Manager, at fair value for $936,995,797.	Note 3. Agreements and Related Party Transactions Investment Advisory Agreement: Base Management Fee The base management fee is calculated an annual rate of 1.25% of the value of the Company’s net assets as of the beginning of the first calendar day of the applicable quarter adjusted for share issuances and repurchases and is payable quarterly in arrears. For purposes of the Investment Advisory Agreement, net assets means the Company’s assets less liabilities determined in accordance with GAAP. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, the base management fees incurred by the Company were $2,049. Incentive Fees The incentive fee consists of two components that are independent of each other, with the result that one component may be payable even if the other is not. A portion of the incentive fee is based on a percentage of the Company’s income and a portion is based on a percentage of the Company’s capital gains, each as described below. (i) Income based incentive fee (the “Income Incentive Fee”) The Income Incentive Fee is based on Pre-Incentive Fee Net Investment Income Returns. “Pre-Incentive Fee Net Investment Income Returns” means, as the context requires, either the dollar value of, or percentage rate of return on the value of net assets at the end of the immediate preceding quarter, adjusted for share issuances and repurchases, from, interest income, dividend income and any other income (including any other fees (other than fees for providing managerial assistance), such as commitment, origination, structuring, diligence and consulting fees or other fees that are received from portfolio companies) accrued during the calendar quarter, minus operating expenses accrued for the quarter (including the management fee, expenses payable under the Administration Agreement and any interest expense or fees on any credit facilities or outstanding debt and dividends paid on any issued and outstanding preferred shares, but excluding the incentive fee and any distribution or shareholder servicing fees). Pre-Incentive Fee Net Investment Income Returns include, in the case of investments with a deferred interest feature (such as original issue discount, debt instruments with PIK interest and zero coupon securities), accrued income that has not yet been received in cash. Pre-Incentive Fee Net Investment Income Returns do not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation. The impact of expense support payments and recoupments are also excluded from Pre-Incentive Fee Net Investment Income Returns. Pre-Incentive Fee Net Investment Income Returns, expressed as a rate of return on the value of the Company’s net assets at the end of the immediate preceding quarter, is compared to a “hurdle rate” of return of 1.25% per quarter (5.0% annualized). The Company pays the Investment Adviser quarterly in arrears an Income Incentive Fee with respect to the Company’s Pre-Incentive Fee Net Investment Income Returns in each calendar quarter as follows: ● No incentive fee based on Pre-Incentive Fee Net Investment Income Returns in any calendar quarter in which Pre-Incentive Fee Net Investment Income Returns do not exceed the hurdle rate of 1.25% per quarter ( 5.0% annualized); ● 100% of the dollar amount of Pre-Incentive Fee Net Investment Income Returns with respect to that portion of such Pre-Incentive Fee Net Investment Income Returns, if any, that exceeds the hurdle rate but is less than a rate of return of 1.43% ( 5.72% annualized). This portion of Pre-Incentive Fee Net Investment Income Returns that exceeds the hurdle rate but is less than 1.43% is referred to as the “catch-up” provision; and ● 12.5% of the dollar amount of Pre-Incentive Fee Net Investment Income Returns, if any, that exceed a rate of return of 1.43% ( 5.72% annualized). This reflects that once the hurdle rate is reached and the catch-up is achieved, 12.5% of all Pre-Incentive Fee Net Investment Income Pre-Incentive Fee Net Investment Income Returns thereafter are allocated to the Investment Adviser. The sum of these calculations yields the Income Incentive Fee. This amount is appropriately adjusted for any share issuances or repurchases during the quarter. During the period from June 30, 2023 (commencement of operations) to September 30, 2023, the Investment Adviser agreed to irrevocably waive $340 of Income Incentive Fees payable pursuant to the Investment Advisory Agreement. After taking into account the waiver, the Income Incentive Fee incurred for the period from June 30, 2023 (commencement of operations) to September 30, 2023 was $2,034 rather than $2,374. (ii) Capital gains based incentive fee (the “Capital Gain Incentive Fee”) The second component of the incentive fee, the Capital Gain Incentive Fee, is payable at the end of each calendar year in arrears. The amount payable equals: ● 12.5% of cumulative realized capital gains from July 1, 2023 through the end of each calendar 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 Fee. Realized capital gains and losses include gains and losses on investments, foreign currencies, including gains and losses on borrowings in foreign currencies, derivative contracts and any income tax related to cumulative aggregate realized gains and losses. Each year, the fee paid for the Capital Gain Incentive Fee is net of the aggregate amount of any previously paid capital gains incentive fee for all prior periods. During the period from June 30, 2023 (commencement of operations) to September 30, 2023, the Company did not accrue a Capital Gain Incentive Fee. As of September 30, 2023, there was no Capital Gain Incentive Fee payable as calculated under the Investment Advisory Agreement as described above. Any payment due for a Capital Gain Incentive Fee under the terms of the Investment Advisory Agreement is calculated in arrears at the end of each calendar year. In accordance with GAAP, the Company also is required to include the aggregate unrealized capital appreciation on investments in the calculation and accrue a capital gain incentive fee on a quarterly basis, as if such unrealized capital appreciation were realized, even though such unrealized capital appreciation is not permitted to be considered in calculating the fee actually payable under the Investment Advisory Agreement, as applicable. There can be no assurance that any such unrealized capital appreciation will be realized in the future. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, there was no accrual of the capital gain incentive fee under GAAP. As of September 30, 2023, there was no cumulative accrual for the capital gain incentive fee under GAAP included in management and incentive fees payable on the Consolidated Statement of Financial Condition. Administration Agreement: As of September 30, 2023, included in accounts payable and other liabilities is $212 for accrued allocated shared services under the Administration Agreement. Each of the Investment Advisory Agreement and the Administration Agreement was approved by the Board, and both became effective on April 28, 2023 and will continue in effect for an initial term of two years. The Company may terminate the Investment Advisory Agreement or the Administration Agreement, without payment of any penalty, upon 60 days’ written notice. Managing Dealer Agreement: The Managing Dealer is a broker-dealer registered with the SEC and a member of the Financial Industry Regulatory Authority (“FINRA”). The Managing Dealer Agreement may be terminated at any time, without the payment of any penalty, by vote of a majority of the Company’s trustees who are not “interested persons”, as defined in the 1940 Act, of the Company and who have no direct or indirect financial interest in the operation of the Company’s distribution and servicing plan or the Managing Dealer Agreement or by vote a majority of the outstanding voting securities of the Company, on not more than 60 days’ written notice to the Managing Dealer or the Investment Adviser. The Managing Dealer Agreement will automatically terminate in the event of its assignment, as defined in the 1940 Act. Distribution and Servicing Plan: beginning of the first calendar day of each applicable quarter. The shareholder servicing and/or distribution fees are calculated and paid separately for each class. ​ ​ ​ ​ ​ ​ Shareholder Servicing ​ ​ ​ and/or Distribution Fee ​ ​ ​ as a % of NAV ​ Class S Shares 0.85 % Class D Shares 0.25 % Class I Shares N/A ​ ​ The shareholder servicing and/or distribution fees paid under the Distribution and Servicing Plan are used primarily to compensate the Managing Dealer for such services provided in connection with the offering and sale of shares of the Company, and/or to reimburse the Managing Dealer for related expenses incurred, including payments by the Managing Dealer to compensate or reimburse brokers, other financial institutions or other industry professionals, for distribution services and sales support services provided and related expenses. Payments of the shareholder servicing and/or distribution fee are also used to compensate the Managing Dealer for personal services and/or the maintenance of shareholder accounts services provided to shareholders in the related share class and may be made without regard to expenses actually incurred. Payments of the shareholder servicing and/or distribution fees on behalf of a particular share class must be in consideration of services rendered for or on behalf of such class. In addition to the shareholder servicing and/or distribution fees, the Company also pays the Managing Dealer certain additional fees for its services under the Distribution and Servicing Plan, which are borne indirectly by all shareholders of the Company. Any fees paid pursuant to the Distribution and Servicing Plan may not exceed the maximum amounts, if any, as may from time to time be permitted by FINRA rules. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, the Company did not Expense Support and Conditional Reimbursement Agreement: forty-five days Following any calendar month in which Available Operating Funds (as defined below) exceed the cumulative distributions accrued to the Company’s shareholders based on distributions declared with respect to record dates occurring in such calendar month (the amount of such excess being hereinafter referred to as “Excess Operating Funds”), the Company shall pay such Excess Operating Funds, or a portion thereof, to the Investment Adviser until such time as all Expense Support Payments made by the Investment Adviser to the Company within three years The Company’s obligation to make a Reimbursement Payment shall automatically become a liability of the Company on the last business day of the applicable calendar month, except to the extent the Investment Adviser has waived its right to receive such payment for the applicable month. The following table presents a summary of Expense Support Payments and the related Reimbursement Payments since the Company’s commencement of operations: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Expense Support ​ Reimbursement ​ ​ ​ ​ Payments by Investment ​ Payments to Investment ​ Unreimbursed Expense For the Month Ended ​ Adviser ​ Adviser ​ Support Payments June 30, 2023 ​ $ 1,257 ​ $ — ​ $ 1,257 Total ​ $ 1,257 ​ $ — ​ $ 1,257 ​ Public Offering Escrow Agreement: Other Related Party Transactions: The Administrator pays for certain unaffiliated third-party expenses incurred by the Company. Such expenses include postage, printing, office supplies, rating agency fees and professional fees. These expenses are not marked-up and represent the same amount the Company would have paid had the Company paid the expenses directly. These expenses are subsequently reimbursed in cash. There were $3,410 of expenses reimbursed to the Administrator for the period from June 30, 2023 (commencement of operations) to September 30, 2023. As of September 30, 2023, $3,639, which includes $1,257 of Expense Support Payments, of reimbursable expenses that were paid by the Administrator on behalf of the Company were included in accounts payable and accrued expenses on the Consolidated Statement of Financial Condition. The Company is party to an unsecured revolving credit facility with the Investment Adviser (the “Adviser Revolver”) which, as of September 30, 2023, permits the Company to borrow a maximum of $50,000 and expires on July 3, 2026.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 5. Fair Value Measurements The Fund follows ASC Topic 820 for measuring fair value. Fair value is the price that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Where available, fair value is based on observable market prices or parameters, or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation models involve some level of management estimation and judgment, the degree of which is dependent on the price observability for the financial instruments or market and the financial instrument complexity. Management’s fair value analysis includes the value of any unfunded loan commitments. Financial instruments recorded at fair value on the financial statements are categorized for disclosure purposes based upon the level of judgment associated with the inputs used to measure their value. The valuation hierarchical levels are based upon the observability of the inputs to the valuation of the financial instrument as of the measurement date. The three levels are defined as follows: Level 1: Level 2: Level 3: In certain cases, the inputs used to measure fair value fall into different levels of the fair value hierarchy. In such cases, a financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Management’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 financial instrument. Management assesses the levels of financial instruments at each measurement date, and transfers between levels are recognized at the end of the period in which the event or change in circumstances that caused the transfers occurred. There were no transfers among Level 1 2 3 Note 5. Fair Value Measurements (continued) Level 1 investments are valued using quoted market prices. Level 2 investments are valued using market consensus prices that are corroborated by observable market data and quoted market prices for similar assets and liabilities. Level 3 investments are valued at fair value as determined in good faith by management under a consistently applied valuation process. All investments as of June 30, 2023 were valued using Level 3 inputs of the fair value hierarchy. As of June 30, 2023, money market funds included in restricted cash and cash equivalents were valued using Level 1 inputs. When determining fair value of Level 3 debt investments, management may take into account the following factors, where relevant, in determining the fair value of the investments: the enterprise value of a portfolio company, the nature and realizable value of any collateral, the portfolio company’s ability to make payments and its earnings, discounted cash flows, the markets in which the portfolio company does business, comparisons to publicly traded securities and changes in the interest rate environment and the credit markets generally that affect the price at which similar investments are made and other relevant factors. The primary method for determining enterprise value uses a multiple analysis whereby appropriate multiples are applied to the portfolio company’s net income before net interest expense, income tax expense, depreciation and amortization (“EBITDA”). The enterprise value analysis is performed to determine if debt investments are credit impaired. If debt investments are credit impaired, the Fund will use the enterprise value analysis or a liquidation basis analysis to determine fair value. For debt investments that are not determined to be credit impaired, the Fund uses a market interest rate yield analysis to determine fair value. Due to the inherent uncertainty of determining the fair value of Level 3 instruments that do not have a readily available market value, the fair value of the financial instruments may differ significantly from the values that would have been used had a ready market existed for such financial instruments and may differ materially from the values that are ultimately received or settled. Further, such financial instruments are generally subject to legal and other restrictions or otherwise are less liquid than publicly traded financial instruments. If required to liquidate a portfolio investment in a forced or liquidation sale, the Fund could realize significantly less than the value at which such investment had previously been recorded. The Fund’s investments are subject to market risk. Market risk is the potential for changes in the value due to market changes. Market risk is directly impacted by the volatility and liquidity in the markets in which the investments are traded. The following tables present fair value measurements of the Fund’s investments and indicate the fair value hierarchy of the valuation techniques utilized by the Fund to determine such fair value as of June 30, 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of June 30, 2023 ​ ​ ​ Fair Value Measurements Using Description ​ Level 1 Level 2 Level 3 Total Assets: ​ ​ ​ ​ Debt Investments (1) ​ $ — ​ $ — ​ $ 935,310,172 ​ $ 935,310,172 Money Market Funds (1)(2) ​ 2,771,624 ​ — ​ — ​ 2,771,624 Total Assets ​ $ 2,771,624 ​ $ — ​ $ 935,310,172 ​ $ 938,081,796 (1) Refer to the Schedule of Investments for further details.

(2) The Fund valued $831,715,991 and $103,594,181 of loans using EBITDA and revenue multiples, respectively. All loans were also valued using the market rate approach. The above tables are not intended to be all-inclusive but rather to provide information on significant unobservable inputs and valuation techniques used by the Fund. The significant unobservable inputs used in the fair value measurement of the Fund’s debt investments are EBITDA multiples, revenue multiples and market interest rates. The Fund uses EBITDA multiples and, to a lesser extent, revenue multiples on its debt investments to determine any credit gains or losses. Increases or decreases in either of these inputs in isolation would have resulted in a significantly lower or higher fair value measurement. The Fund uses market interest rates for loans to determine if the effective yield on a loan is commensurate with the market yields for that type of loan. If a loan’s effective yield was significantly less than the market yield for a similar loan with a similar credit profile, then the resulting fair value of the loan may have been lower. Other Financial Assets and Liabilities ASC Topic 820 requires disclosure of the fair value of financial instruments for which it is practical to estimate such value. As a result, with the exception of the line item titled “debt” which is reported at cost, all assets and liabilities approximate fair value on the Statement of Financial Condition due to their short maturity. Fair value of the Fund’s debt is estimated using Level 3 inputs by discounting remaining payments using applicable implied market rates. Note 5.

Fair Value Measurements The Company follows ASC Topic 820 for measuring fair value. Fair value is the price that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Where available, fair value is based on observable market prices or parameters, or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation models involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the assets or liabilities or market and the assets’ or liabilities’ complexity. The Company’s fair value analysis includes an analysis of the value of any unfunded loan commitments. Assets and liabilities are categorized for disclosure purposes based upon the level of judgment associated with the inputs used to measure their value. The valuation hierarchical levels are based upon the transparency of the inputs to the valuation of the asset or liability as of the measurement date. The three levels are defined as follows: Level 1: Level 2: Level 3: In certain cases, the inputs used to measure fair value fall into different levels of the fair value hierarchy. In such cases, an asset’s or a liability’s categorization within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. The Company assesses the levels of assets and liabilities at each measurement date, and transfers between levels are recognized on the actual date of the event or change in circumstances that caused the transfers. There were no transfers among Level 1, 2 and 3 of the fair value hierarchy for assets and liabilities during the period from June 30, 2023 (commencement of operations) to September 30, 2023. The following section describes the valuation techniques used by the Company to measure different assets and liabilities at fair value and includes the level within the fair value hierarchy in which the assets and liabilities are categorized. Investments Level 1 investments are valued using quoted market prices. Level 2 investments are valued using market consensus prices that are corroborated by observable market data and quoted market prices for similar assets and liabilities. Level 3 investments are valued at fair value as determined in good faith by the Board, based on input of management, the audit committee and independent valuation firms that have been engaged at the direction of the Board to assist in the valuation of each portfolio investment without a readily available market quotation at least once during a trailing twelve-month period under a valuation policy and a consistently applied valuation process. This valuation process is conducted at the end of each fiscal quarter, with approximately 25% (based on the number of portfolio companies) of the Company’s valuations of debt and equity investments without readily available market quotations subject to review by an independent valuation firm. As of September 30, 2023, $139,934 and $1,038,699 of investments were valued using Level 2 inputs and Level 3 inputs, respectively. As of September 30, 2023, all money market funds included in cash and cash equivalents and restricted cash and cash equivalents were valued using Level 1 inputs. When determining fair value of Level 3 debt and equity investments, the Company takes into account the following factors, where relevant: the enterprise value of a portfolio company, the nature and realizable value of any collateral, the portfolio company’s ability to make payments and its earnings and discounted cash flows, the markets in which the portfolio company does business, comparisons to publicly traded securities, and changes in the interest rate environment and the credit markets generally that affect the price at which similar investments are made and other relevant factors. The primary method for determining enterprise value uses a multiple analysis whereby appropriate multiples are applied to the portfolio company’s net income before net interest expense, income tax expense, depreciation and amortization (“EBITDA”). A portfolio company’s EBITDA can include pro-forma adjustments for items such as acquisitions, divestitures, or expense reductions. The enterprise value analysis is performed to determine the value of equity investments and to determine if debt investments are credit impaired. If debt investments are credit impaired, the Company will use the enterprise value analysis or a liquidation basis analysis to determine fair value. For debt investments that are not determined to be credit impaired, the Company uses a market interest rate yield analysis to determine fair value. In addition, for certain debt investments, the Company bases its valuation on indicative bid and ask prices provided by an independent third-party pricing service. Bid prices reflect the highest price that the Company and others may be willing to pay. Ask prices represent the lowest price that the Company and others may be willing to accept. The Company generally uses the midpoint of the bid/ask range as its best estimate of fair value of such investment. Due to the inherent uncertainty of determining the fair value of Level 3 investments that do not have a readily available market value, the fair value of the investments may differ significantly from the values that would have been used had a ready market existed for such investments and may differ materially from the values that are ultimately received or settled. Further, such investments are generally subject to legal and other restrictions or otherwise are less liquid than publicly traded instruments. If the Company were required to liquidate a portfolio investment in a forced or liquidation sale, the Company could realize significantly less than the value at which such investment had previously been recorded. The Company’s investments are subject to market risk. Market risk is the potential for changes in the value due to market changes. Market risk is directly impacted by the volatility and liquidity in the markets in which the investments are traded.

Basis of presentation	Basis of presentation: Financial Services Investment Companies.	Basis of presentation: Financial Services - Investment Companies The accompanying consolidated financial statements of the Company and related financial information have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) as established by the Financial Accounting Standards Board (“FASB”) for financial information and pursuant to the requirements for reporting on Form 10-K and Regulation S-X. In the opinion of management, the consolidated financial statements reflect all adjustments and reclassifications consisting solely of normal accruals that are necessary for the fair presentation of financial results as of and for the periods presented. All intercompany balances and transactions have been eliminated.
Fair value of financial instruments	Fair value of financial instruments: Fair Value Measurement .	Fair value of financial instruments: Fair Value Measurement . The availability of observable inputs can vary depending on the financial instrument and is affected by a wide variety of factors, including, for example, the type of product, whether the product is new, whether the product is traded on an active exchange or in the secondary market and the current market conditions. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for financial instruments classified as Level 3. Any changes to the valuation methodology are reviewed by management and the Company’s board of trustees (the “Board”) to confirm that the changes are appropriate. As markets change, new products develop and the pricing for products becomes more or less transparent, the Company will continue to refine its valuation methodologies. See Note 5. Fair Value Measurements for further description of fair value methodology.

Foreign currency translation	Foreign currency translation: (1) restricted cash and cash equivalents, investments at fair value, interest receivable, debt, interest payable and other assets and payables - at the spot exchange rate on the last business day of the period; and (2) purchases and sales of investments, borrowings and payments of debt, income and expenses - at the exchange rates prevailing on the respective dates of such transactions. Net assets and fair values are presented based on the applicable foreign exchange rates described above and fluctuations arising from the translation of assets and liabilities are included with the net change in unrealized appreciation (depreciation) on translation of assets and liabilities in foreign currencies on the Statement of Operations. Realized gains or losses arising from foreign currency transactions are reported as components of the net realized gain (loss) on foreign currency transactions on the Statement of Operations. Foreign security and currency transactions involve certain considerations and risks not typically associated with investing in U.S. companies. These risks include, but are not limited to, currency fluctuations and revaluations and future adverse political, social and economic developments, which could cause investments in foreign markets to be less liquid and prices more volatile than those of comparable U.S. companies or U.S. government securities.

Revenue recognition	Revenue recognition: Investments and related investment income: For investments with contractual payment-in-kind (“PIK”) interest, contractual interest is accrued, added to the principal balance and generally becomes due at maturity. For the period from June 8, 2023 (commencement of operations) to June 30, 2023, the Fund capitalized PIK interest of $205,621 into the principal balance of certain debt investments. Realized gains or losses on investments are measured by the difference between the net proceeds from the disposition and the amortized cost basis of investment, without regard to unrealized gains or losses previously recognized. The Fund reports the changes in fair value of investments that are measured at fair value as a component of the net change in unrealized appreciation (depreciation) on investments on the Statement of Operations. Non-accrual loans: Interest payments received on non-accrual loans are recognized as income or applied to principal depending upon management’s judgment. When the Fund receives principal payments on a non-accrual loan in an amount that exceeds the loan’s amortized cost, it may recognize the excess principal payment as interest income based on upon management’s judgement. Non-accrual loans are restored to accrual status when past due principal and interest is paid, and, in management’s judgment, payments are likely to remain current. As of June 30, 2023, the Fund had no portfolio company investments on non-accrual status.	Revenue recognition: Investments and related investment income: Loan origination fees, original issue discount and market discount or premium are capitalized, and the Company accretes or amortizes such amounts over the life of the loan as interest income. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, interest income included $1,196 of accretion of discounts. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, the Company received loan origination fees of $2,432. For investments with contractual payment-in-kind (“PIK”) interest, which represents contractual interest accrued and added to the principal balance that generally becomes due at maturity, the Company will not accrue PIK interest if the portfolio company valuation indicates that the PIK interest is not collectible. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, interest income included $601 of PIK interest and the Company capitalized PIK interest of $513 into the principal balance of certain debt investments. In addition, the Company generates revenue in the form of amendment, structuring or due diligence fees, fees for providing managerial assistance, consulting fees, administrative agent fees, and prepayment premiums on loans. The Company records these fees as fee income when earned. All other income is recorded into income when earned. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, fee income included no prepayment premiums. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, the Company received interest and fee income in cash, which excludes capitalized loan origination fees, in the amount of $14,403. Dividend income on equity securities is recorded as dividend income on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. The Company may have certain preferred equity securities in the portfolio that contain a PIK dividend provision that are accrued and recorded as income at the contractual rates, if deemed collectible. The accrued PIK and non-cash dividends are capitalized to the cost basis of the preferred equity security and are generally collected when redeemed by the issuer. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, the Company did not not Dividend income on common equity securities is recorded on the record date for private portfolio companies or on the ex-dividend date for publicly traded portfolio companies. Each distribution received from limited liability company (“LLC”) and limited partnership (“LP”) investments is 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 equity investments in LLCs and LPs as dividend income unless there are sufficient accumulated tax-basis earnings and profits in the LLC or LP prior to the distribution. Distributions that are classified as a return of capital are recorded as a reduction in the amortized cost basis of the investment.

[1] The total principal amount is presented for debt investments while the number of shares or units owned is presented for equity investments. Equity investments are non-income producing securities, unless otherwise noted. Ownership of certain equity investments occurs through a holding company or partnership. The fair values of investments were valued using significant unobservable inputs, unless otherwise noted. See Note 5. Fair Value Measurements. The fair value of this investment was valued using Level 2 inputs. See Note 5. Fair Value Measurements. The investment is treated as a non-qualifying asset under Section 55(a) of the Investment Company Act of 1940, as amended (the “1940 Act”). Under the 1940 Act, the Company cannot acquire any non-qualifying asset unless, at the time the acquisition is made, qualifying assets represent at least 70% of the Company’s total assets. As of September 30, 2023, total non-qualifying assets at fair value represented 16.0% of the Company’s total assets calculated in accordance with the 1940 Act. The majority of the investments bear interest at a rate that is permitted to be determined by reference to the Secured Overnight Financing Rate (“SOFR” or “SF”), Euro Interbank Offered Rate (“EURIBOR” or “E”), Canadian Bankers Acceptance Rate (“CDOR” or “C”), Australian Interbank Rate (“AUD” or “A”), Sterling Overnight Index Average (“SONIA” or “SN”) or the London Interbank Offered Rate (“LIBOR” or “L”) denominated in U.S. dollars which reset daily, monthly, quarterly, semiannually or annually. For each, the Company has provided the spread over the applicable index and the weighted average current interest rate in effect as of September 30, 2023. Certain investments are subject to an interest rate floor. For fixed rate loans, a spread above a reference rate is not applicable. For positions with multiple outstanding contracts, the spread for the largest outstanding contract is shown. Listed below are the index rates as of September 30, 2023, which was the last business day of the period on which the applicable index rates were determined. The actual index rate for each loan listed may not be the applicable index rate outstanding as of September 30, 2023, as the loan may have priced or repriced based on an index rate prior to September 30, 2023. For positions with multiple interest rate contracts, the interest rate shown is a weighted average current interest rate in effect as of September 30, 2023.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Note 1. Organization GCP SG Warehouse 2022-1 (“GCP SG Warehouse” or the “Fund”) was organized in the state of Delaware on December 9, 2022 as a Delaware statutory trust for the purpose of making investments primarily through direct lending to U.S. private companies in the middle market in the form of one stop and other senior secured loans. On June 8, 2023, the Fund entered into a credit agreement (the “GCP Warehouse Credit Facility”) by and among the Fund, as borrower, Société Générale, as administrative agent, the lenders and the subordinated noteholders party thereto, and Wilmington Trust, National Association as collateral agent, collateral administrator, custodian and collateral custodian. In connection with entering into the GCP Warehouse Credit Facility, the Fund’s trust agreement was amended and restated (the “Amended Trust Agreement”) and the Fund commenced operations. The Fund is beneficially owned by GCP HS Fund, a Delaware statutory trust, and GCP CLO Holdings Sub LP (“GCP CLO Sub”), an exempted limited partnership registered in the Cayman Islands (together the “Beneficial Owners”). GC Investment Management LLC (the “Investment Manager”) serves as the investment manager of GCP HS Fund. GC Investment Management LLC is a relying adviser of GC OPAL Advisors LLC, which is a registered investment adviser with the Securities and Exchange Commission.	Note 1. Organization Golub Capital Private Credit Fund (“GCRED” or the “Company”), is a Delaware statutory trust formed on May 13, 2022. The Company is an externally managed, non-diversified, closed-end management investment company that has elected to be regulated as a business development company (“BDC”) under the Investment Company Act of 1940, as amended (the “1940 Act”). In addition, for U.S. federal income tax purposes, beginning with its tax year ended September 30, 2023, the Company intends to elect to be treated as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). The Company commenced operations on June 30, 2023. The Company’s fiscal year end is September 30. The Company’s investment objective is to generate current income and capital appreciation by investing primarily in privately originated and privately negotiated investments, predominantly through direct lending to U.S. private companies in the middle-market and upper middle-market in the form of one stop and other senior secured loans. The Company may selectively invest in second lien and subordinated loans (including loans that rank senior only to a borrower’s equity securities and ranks junior to all of such borrower’s other indebtedness in priority of payment) of private companies. The Company may also invest in liquid credit instruments, including secured floating rate syndicated loans, securitized products and corporate bonds, and the Company’s portfolio may, but will not necessarily, initially be comprised of a greater percentage of such instruments than it will as the Company’s investment program matures, though the exact allocation may vary from time to time depending on market conditions and available investment opportunities. The Company’s portfolio may also include equity interests such as preferred equity, debt investments accompanied by equity-related securities (including warrants) and, to a limited extent, common equity investments, which generally would be obtained as part of providing a broader financing solution. The Company has entered into an investment advisory agreement (the “Investment Advisory Agreement”) with GC Advisors, LLC (the “Investment Adviser”), under which the Investment Adviser manages the day-to-day operations of, and provides investment advisory services to, the Company. Under an administration agreement (the “Administration Agreement”) the Company is provided with certain services by an administrator, which is currently Golub Capital LLC (the “Administrator”). The Company offers on a continuous basis up to $5.0 billion of common shares of beneficial interest pursuant to an offering registered with the Securities and Exchange Commission (the “SEC”). The Company has applied for exemptive relief from the SEC that, if granted, will permit the Company to offer to sell any combination of three classes of common shares, Class S shares, Class D shares and Class I shares, with a dollar value up to the maximum offering amount (the “Public Offering”). There is no assurance, however, that the relief will be granted. Beginning in April 2023, the Company commenced a separate private offering of Class F shares (the “Private Offering”) to certain accredited investors (the “Private Offering Investors”). On June 14, 2023, the Company completed the Private Offering and entered into subscription agreements with the Private Offering Investors for total commitments of $650.3 million to purchase the Company’s Class F shares. The offer and sale of these Class F Shares was exempt from the registration provisions of the Securities Act of 1933, as amended, pursuant to Section 4(a)(2) and/or Regulation S thereunder. Following the completion of the Private Offering, the Company’s Class F Shares were reclassified as Class I Shares (the “Reclassification”). On June 30, 2023, the Company received the Private Offering subscription proceeds and issued 26,010,927.600 shares of the Company’s Class F common shares (reclassified as Class I shares) at a purchase price of $25.00 per share. On July 1, 2023, the Company entered into a Share Purchase and Sale Agreement (the “Share Purchase and Sale Agreement”), by and among the Company, GCP HS Fund, GCP CLO Holdings Sub LP (each, a “Seller” and, collectively, “Sellers”), and the Investment Adviser. Pursuant to the Share Purchase and Sale Agreement, the Company acquired all of the assets and liabilities (the “Seed Assets”) of GCP SG Warehouse 2022-1 (the “CLO Vehicle”) through the purchase from the Sellers of 100% of the beneficial interests in, and 100% of the subordinated notes issued by the CLO Vehicle.

Accounting Policies [Abstract]
Significant Accounting Policies and Recent Accounting Updates	Note 2. Significant Accounting Policies and Recent Accounting Updates Basis of presentation: Financial Services - Investment Companies The accompanying consolidated financial statements of the Company and related financial information have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) as established by the Financial Accounting Standards Board (“FASB”) for financial information and pursuant to the requirements for reporting on Form 10-K and Regulation S-X. In the opinion of management, the consolidated financial statements reflect all adjustments and reclassifications consisting solely of normal accruals that are necessary for the fair presentation of financial results as of and for the periods presented. All intercompany balances and transactions have been eliminated. Fair value of financial instruments: Fair Value Measurement . The availability of observable inputs can vary depending on the financial instrument and is affected by a wide variety of factors, including, for example, the type of product, whether the product is new, whether the product is traded on an active exchange or in the secondary market and the current market conditions. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for financial instruments classified as Level 3. Any changes to the valuation methodology are reviewed by management and the Company’s board of trustees (the “Board”) to confirm that the changes are appropriate. As markets change, new products develop and the pricing for products becomes more or less transparent, the Company will continue to refine its valuation methodologies. See Note 5. Fair Value Measurements for further description of fair value methodology. Use of estimates: Consolidation: Assets related to transactions that do not meet ASC Topic 860 requirements for accounting sale treatment are reflected in the Company’s Consolidated Statement of Financial Condition as investments. Those assets are owned by the 2023 Issuer, a special purpose entity, that is consolidated in the Company’s consolidated financial statements. The creditors of the special purpose entity have received security interests in such assets and such assets are not intended to be available to the creditors of GCRED (or any affiliate of GCRED). Cash and cash equivalents and foreign currencies: Restricted cash and cash equivalents: Foreign currency translation: Net assets and fair values are presented based on the applicable foreign exchange rates and fluctuations arising from the translation of assets and liabilities are included with the net change in unrealized appreciation (depreciation) on translation of assets and liabilities in foreign currencies on the Consolidated Statement of Operations. Foreign security and currency transactions involve certain considerations and risks not typically associated with investing in U.S. companies. These risks include, but are not limited to, currency fluctuations and revaluations and future adverse political, social and economic developments, which could cause investments in foreign markets to be less liquid and prices more volatile than those of comparable U.S. companies or U.S. government securities. Revenue recognition: Investments and related investment income: Loan origination fees, original issue discount and market discount or premium are capitalized, and the Company accretes or amortizes such amounts over the life of the loan as interest income. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, interest income included $1,196 of accretion of discounts. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, the Company received loan origination fees of $2,432. For investments with contractual payment-in-kind (“PIK”) interest, which represents contractual interest accrued and added to the principal balance that generally becomes due at maturity, the Company will not accrue PIK interest if the portfolio company valuation indicates that the PIK interest is not collectible. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, interest income included $601 of PIK interest and the Company capitalized PIK interest of $513 into the principal balance of certain debt investments. In addition, the Company generates revenue in the form of amendment, structuring or due diligence fees, fees for providing managerial assistance, consulting fees, administrative agent fees, and prepayment premiums on loans. The Company records these fees as fee income when earned. All other income is recorded into income when earned. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, fee income included no prepayment premiums. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, the Company received interest and fee income in cash, which excludes capitalized loan origination fees, in the amount of $14,403. Dividend income on equity securities is recorded as dividend income on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. The Company may have certain preferred equity securities in the portfolio that contain a PIK dividend provision that are accrued and recorded as income at the contractual rates, if deemed collectible. The accrued PIK and non-cash dividends are capitalized to the cost basis of the preferred equity security and are generally collected when redeemed by the issuer. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, the Company did not not Dividend income on common equity securities is recorded on the record date for private portfolio companies or on the ex-dividend date for publicly traded portfolio companies. Each distribution received from limited liability company (“LLC”) and limited partnership (“LP”) investments is 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 equity investments in LLCs and LPs as dividend income unless there are sufficient accumulated tax-basis earnings and profits in the LLC or LP prior to the distribution. Distributions that are classified as a return of capital are recorded as a reduction in the amortized cost basis of the investment. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, the Company did not not Investment transactions are accounted for on a trade-date basis. Realized gains or losses on investments are measured by the difference between the net proceeds from the disposition and the amortized cost basis of investment, without regard to unrealized gains or losses previously recognized. The Company reports current period changes in fair value of investments that are measured at fair value as a component of the net change in unrealized appreciation (depreciation) on investment transactions in the Consolidated Statement of Operations. Non-accrual loans: Income taxes: Depending on the level of taxable income earned in a tax year, the Company can determine to retain taxable income in excess of current year dividend distributions and distribute such taxable income in the next tax year. The Company may then be required to incur a 4% excise tax on such income. 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. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, the Company did not The Company accounts for income taxes in conformity with ASC Topic 740 - Income Taxes Dividends and distributions: 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 shareholders, unless a shareholder elects to receive cash. As a result, if the Board authorizes and the Company declares a cash distribution, then shareholders who have not “opted out” of the DRIP will have their cash distribution automatically reinvested in additional shares of the Company’s common shares, rather than receiving the cash distribution. Shares issued under the DRIP will be issued at a price per share equal to the most recent net offering price per share for such shares at the time the distribution is payable. Deferred debt issuance costs: Deferred offering costs:

Related Party Transactions [Abstract]
Agreements and Related Party Transactions	Note 4. Related Party and Affiliate Activity Entities are considered to be an affiliate if they share direct or indirect common ownership or are managed by the Investment Manager, or an affiliate of the Investment Manager. The Investment Manager entered into an agreement to serve as the collateral manager to the GCP Warehouse Credit Facility. Under the terms of the collateral management agreement between the Investment Manager and the Fund (“GCP Warehouse Collateral Management Agreement”), the Investment Manager is entitled to receive an annual fee in an amount equal to 0.25% of the principal balance of the portfolio of loans held by the Fund at the beginning of the collection period relating to each payment date, which is payable quarterly in arrears unless waived or deferred by the Investment Manager. For the period from June 8, 2023 (commencement of operations) to June 30, 2023, the Investment Manager irrevocably waived $130,519 of collateral management fees payable under the GCP Warehouse Collateral Management Agreement. During the period from June 8, 2023 (commencement of operations) to June 30, 2023, the Fund purchased investments from entities managed by the Investment Manager, or an affiliate of the Investment Manager, at fair value for $936,995,797.	Note 3. Agreements and Related Party Transactions Investment Advisory Agreement: Base Management Fee The base management fee is calculated an annual rate of 1.25% of the value of the Company’s net assets as of the beginning of the first calendar day of the applicable quarter adjusted for share issuances and repurchases and is payable quarterly in arrears. For purposes of the Investment Advisory Agreement, net assets means the Company’s assets less liabilities determined in accordance with GAAP. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, the base management fees incurred by the Company were $2,049. Incentive Fees The incentive fee consists of two components that are independent of each other, with the result that one component may be payable even if the other is not. A portion of the incentive fee is based on a percentage of the Company’s income and a portion is based on a percentage of the Company’s capital gains, each as described below. (i) Income based incentive fee (the “Income Incentive Fee”) The Income Incentive Fee is based on Pre-Incentive Fee Net Investment Income Returns. “Pre-Incentive Fee Net Investment Income Returns” means, as the context requires, either the dollar value of, or percentage rate of return on the value of net assets at the end of the immediate preceding quarter, adjusted for share issuances and repurchases, from, interest income, dividend income and any other income (including any other fees (other than fees for providing managerial assistance), such as commitment, origination, structuring, diligence and consulting fees or other fees that are received from portfolio companies) accrued during the calendar quarter, minus operating expenses accrued for the quarter (including the management fee, expenses payable under the Administration Agreement and any interest expense or fees on any credit facilities or outstanding debt and dividends paid on any issued and outstanding preferred shares, but excluding the incentive fee and any distribution or shareholder servicing fees). Pre-Incentive Fee Net Investment Income Returns include, in the case of investments with a deferred interest feature (such as original issue discount, debt instruments with PIK interest and zero coupon securities), accrued income that has not yet been received in cash. Pre-Incentive Fee Net Investment Income Returns do not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation. The impact of expense support payments and recoupments are also excluded from Pre-Incentive Fee Net Investment Income Returns. Pre-Incentive Fee Net Investment Income Returns, expressed as a rate of return on the value of the Company’s net assets at the end of the immediate preceding quarter, is compared to a “hurdle rate” of return of 1.25% per quarter (5.0% annualized). The Company pays the Investment Adviser quarterly in arrears an Income Incentive Fee with respect to the Company’s Pre-Incentive Fee Net Investment Income Returns in each calendar quarter as follows: ● No incentive fee based on Pre-Incentive Fee Net Investment Income Returns in any calendar quarter in which Pre-Incentive Fee Net Investment Income Returns do not exceed the hurdle rate of 1.25% per quarter ( 5.0% annualized); ● 100% of the dollar amount of Pre-Incentive Fee Net Investment Income Returns with respect to that portion of such Pre-Incentive Fee Net Investment Income Returns, if any, that exceeds the hurdle rate but is less than a rate of return of 1.43% ( 5.72% annualized). This portion of Pre-Incentive Fee Net Investment Income Returns that exceeds the hurdle rate but is less than 1.43% is referred to as the “catch-up” provision; and ● 12.5% of the dollar amount of Pre-Incentive Fee Net Investment Income Returns, if any, that exceed a rate of return of 1.43% ( 5.72% annualized). This reflects that once the hurdle rate is reached and the catch-up is achieved, 12.5% of all Pre-Incentive Fee Net Investment Income Pre-Incentive Fee Net Investment Income Returns thereafter are allocated to the Investment Adviser. The sum of these calculations yields the Income Incentive Fee. This amount is appropriately adjusted for any share issuances or repurchases during the quarter. During the period from June 30, 2023 (commencement of operations) to September 30, 2023, the Investment Adviser agreed to irrevocably waive $340 of Income Incentive Fees payable pursuant to the Investment Advisory Agreement. After taking into account the waiver, the Income Incentive Fee incurred for the period from June 30, 2023 (commencement of operations) to September 30, 2023 was $2,034 rather than $2,374. (ii) Capital gains based incentive fee (the “Capital Gain Incentive Fee”) The second component of the incentive fee, the Capital Gain Incentive Fee, is payable at the end of each calendar year in arrears. The amount payable equals: ● 12.5% of cumulative realized capital gains from July 1, 2023 through the end of each calendar 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 Fee. Realized capital gains and losses include gains and losses on investments, foreign currencies, including gains and losses on borrowings in foreign currencies, derivative contracts and any income tax related to cumulative aggregate realized gains and losses. Each year, the fee paid for the Capital Gain Incentive Fee is net of the aggregate amount of any previously paid capital gains incentive fee for all prior periods. During the period from June 30, 2023 (commencement of operations) to September 30, 2023, the Company did not accrue a Capital Gain Incentive Fee. As of September 30, 2023, there was no Capital Gain Incentive Fee payable as calculated under the Investment Advisory Agreement as described above. Any payment due for a Capital Gain Incentive Fee under the terms of the Investment Advisory Agreement is calculated in arrears at the end of each calendar year. In accordance with GAAP, the Company also is required to include the aggregate unrealized capital appreciation on investments in the calculation and accrue a capital gain incentive fee on a quarterly basis, as if such unrealized capital appreciation were realized, even though such unrealized capital appreciation is not permitted to be considered in calculating the fee actually payable under the Investment Advisory Agreement, as applicable. There can be no assurance that any such unrealized capital appreciation will be realized in the future. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, there was no accrual of the capital gain incentive fee under GAAP. As of September 30, 2023, there was no cumulative accrual for the capital gain incentive fee under GAAP included in management and incentive fees payable on the Consolidated Statement of Financial Condition. Administration Agreement: As of September 30, 2023, included in accounts payable and other liabilities is $212 for accrued allocated shared services under the Administration Agreement. Each of the Investment Advisory Agreement and the Administration Agreement was approved by the Board, and both became effective on April 28, 2023 and will continue in effect for an initial term of two years. The Company may terminate the Investment Advisory Agreement or the Administration Agreement, without payment of any penalty, upon 60 days’ written notice. Managing Dealer Agreement: The Managing Dealer is a broker-dealer registered with the SEC and a member of the Financial Industry Regulatory Authority (“FINRA”). The Managing Dealer Agreement may be terminated at any time, without the payment of any penalty, by vote of a majority of the Company’s trustees who are not “interested persons”, as defined in the 1940 Act, of the Company and who have no direct or indirect financial interest in the operation of the Company’s distribution and servicing plan or the Managing Dealer Agreement or by vote a majority of the outstanding voting securities of the Company, on not more than 60 days’ written notice to the Managing Dealer or the Investment Adviser. The Managing Dealer Agreement will automatically terminate in the event of its assignment, as defined in the 1940 Act. Distribution and Servicing Plan: beginning of the first calendar day of each applicable quarter. The shareholder servicing and/or distribution fees are calculated and paid separately for each class. ​ ​ ​ ​ ​ ​ Shareholder Servicing ​ ​ ​ and/or Distribution Fee ​ ​ ​ as a % of NAV ​ Class S Shares 0.85 % Class D Shares 0.25 % Class I Shares N/A ​ ​ The shareholder servicing and/or distribution fees paid under the Distribution and Servicing Plan are used primarily to compensate the Managing Dealer for such services provided in connection with the offering and sale of shares of the Company, and/or to reimburse the Managing Dealer for related expenses incurred, including payments by the Managing Dealer to compensate or reimburse brokers, other financial institutions or other industry professionals, for distribution services and sales support services provided and related expenses. Payments of the shareholder servicing and/or distribution fee are also used to compensate the Managing Dealer for personal services and/or the maintenance of shareholder accounts services provided to shareholders in the related share class and may be made without regard to expenses actually incurred. Payments of the shareholder servicing and/or distribution fees on behalf of a particular share class must be in consideration of services rendered for or on behalf of such class. In addition to the shareholder servicing and/or distribution fees, the Company also pays the Managing Dealer certain additional fees for its services under the Distribution and Servicing Plan, which are borne indirectly by all shareholders of the Company.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 5. Fair Value Measurements The Fund follows ASC Topic 820 for measuring fair value. Fair value is the price that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Where available, fair value is based on observable market prices or parameters, or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation models involve some level of management estimation and judgment, the degree of which is dependent on the price observability for the financial instruments or market and the financial instrument complexity. Management’s fair value analysis includes the value of any unfunded loan commitments. Financial instruments recorded at fair value on the financial statements are categorized for disclosure purposes based upon the level of judgment associated with the inputs used to measure their value. The valuation hierarchical levels are based upon the observability of the inputs to the valuation of the financial instrument as of the measurement date. The three levels are defined as follows: Level 1: Level 2: Level 3: In certain cases, the inputs used to measure fair value fall into different levels of the fair value hierarchy. In such cases, a financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Management’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 financial instrument. Management assesses the levels of financial instruments at each measurement date, and transfers between levels are recognized at the end of the period in which the event or change in circumstances that caused the transfers occurred. There were no transfers among Level 1 2 3 Note 5. Fair Value Measurements (continued) Level 1 investments are valued using quoted market prices. Level 2 investments are valued using market consensus prices that are corroborated by observable market data and quoted market prices for similar assets and liabilities. Level 3 investments are valued at fair value as determined in good faith by management under a consistently applied valuation process. All investments as of June 30, 2023 were valued using Level 3 inputs of the fair value hierarchy. As of June 30, 2023, money market funds included in restricted cash and cash equivalents were valued using Level 1 inputs. When determining fair value of Level 3 debt investments, management may take into account the following factors, where relevant, in determining the fair value of the investments: the enterprise value of a portfolio company, the nature and realizable value of any collateral, the portfolio company’s ability to make payments and its earnings, discounted cash flows, the markets in which the portfolio company does business, comparisons to publicly traded securities and changes in the interest rate environment and the credit markets generally that affect the price at which similar investments are made and other relevant factors. The primary method for determining enterprise value uses a multiple analysis whereby appropriate multiples are applied to the portfolio company’s net income before net interest expense, income tax expense, depreciation and amortization (“EBITDA”). The enterprise value analysis is performed to determine if debt investments are credit impaired. If debt investments are credit impaired, the Fund will use the enterprise value analysis or a liquidation basis analysis to determine fair value. For debt investments that are not determined to be credit impaired, the Fund uses a market interest rate yield analysis to determine fair value. Due to the inherent uncertainty of determining the fair value of Level 3 instruments that do not have a readily available market value, the fair value of the financial instruments may differ significantly from the values that would have been used had a ready market existed for such financial instruments and may differ materially from the values that are ultimately received or settled. Further, such financial instruments are generally subject to legal and other restrictions or otherwise are less liquid than publicly traded financial instruments. If required to liquidate a portfolio investment in a forced or liquidation sale, the Fund could realize significantly less than the value at which such investment had previously been recorded. The Fund’s investments are subject to market risk. Market risk is the potential for changes in the value due to market changes. Market risk is directly impacted by the volatility and liquidity in the markets in which the investments are traded. The following tables present fair value measurements of the Fund’s investments and indicate the fair value hierarchy of the valuation techniques utilized by the Fund to determine such fair value as of June 30, 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of June 30, 2023 ​ ​ ​ Fair Value Measurements Using Description ​ Level 1 Level 2 Level 3 Total Assets: ​ ​ ​ ​ Debt Investments (1) ​ $ — ​ $ — ​ $ 935,310,172 ​ $ 935,310,172 Money Market Funds (1)(2) ​ 2,771,624 ​ — ​ — ​ 2,771,624 Total Assets ​ $ 2,771,624 ​ $ — ​ $ 935,310,172 ​ $ 938,081,796 (1) Refer to the Schedule of Investments for further details.

(2) The Fund valued $831,715,991 and $103,594,181 of loans using EBITDA and revenue multiples, respectively. All loans were also valued using the market rate approach. The above tables are not intended to be all-inclusive but rather to provide information on significant unobservable inputs and valuation techniques used by the Fund. The significant unobservable inputs used in the fair value measurement of the Fund’s debt investments are EBITDA multiples, revenue multiples and market interest rates. The Fund uses EBITDA multiples and, to a lesser extent, revenue multiples on its debt investments to determine any credit gains or losses. Increases or decreases in either of these inputs in isolation would have resulted in a significantly lower or higher fair value measurement. The Fund uses market interest rates for loans to determine if the effective yield on a loan is commensurate with the market yields for that type of loan. If a loan’s effective yield was significantly less than the market yield for a similar loan with a similar credit profile, then the resulting fair value of the loan may have been lower. Other Financial Assets and Liabilities ASC Topic 820 requires disclosure of the fair value of financial instruments for which it is practical to estimate such value. As a result, with the exception of the line item titled “debt” which is reported at cost, all assets and liabilities approximate fair value on the Statement of Financial Condition due to their short maturity. Fair value of the Fund’s debt is estimated using Level 3 inputs by discounting remaining payments using applicable implied market rates. Note 5.

Fair Value Measurements The Company follows ASC Topic 820 for measuring fair value. Fair value is the price that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Where available, fair value is based on observable market prices or parameters, or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation models involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the assets or liabilities or market and the assets’ or liabilities’ complexity. The Company’s fair value analysis includes an analysis of the value of any unfunded loan commitments. Assets and liabilities are categorized for disclosure purposes based upon the level of judgment associated with the inputs used to measure their value. The valuation hierarchical levels are based upon the transparency of the inputs to the valuation of the asset or liability as of the measurement date. The three levels are defined as follows: Level 1: Level 2: Level 3: In certain cases, the inputs used to measure fair value fall into different levels of the fair value hierarchy. In such cases, an asset’s or a liability’s categorization within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. The Company assesses the levels of assets and liabilities at each measurement date, and transfers between levels are recognized on the actual date of the event or change in circumstances that caused the transfers. There were no transfers among Level 1, 2 and 3 of the fair value hierarchy for assets and liabilities during the period from June 30, 2023 (commencement of operations) to September 30, 2023. The following section describes the valuation techniques used by the Company to measure different assets and liabilities at fair value and includes the level within the fair value hierarchy in which the assets and liabilities are categorized. Investments Level 1 investments are valued using quoted market prices. Level 2 investments are valued using market consensus prices that are corroborated by observable market data and quoted market prices for similar assets and liabilities. Level 3 investments are valued at fair value as determined in good faith by the Board, based on input of management, the audit committee and independent valuation firms that have been engaged at the direction of the Board to assist in the valuation of each portfolio investment without a readily available market quotation at least once during a trailing twelve-month period under a valuation policy and a consistently applied valuation process. This valuation process is conducted at the end of each fiscal quarter, with approximately 25% (based on the number of portfolio companies) of the Company’s valuations of debt and equity investments without readily available market quotations subject to review by an independent valuation firm. As of September 30, 2023, $139,934 and $1,038,699 of investments were valued using Level 2 inputs and Level 3 inputs, respectively. As of September 30, 2023, all money market funds included in cash and cash equivalents and restricted cash and cash equivalents were valued using Level 1 inputs. When determining fair value of Level 3 debt and equity investments, the Company takes into account the following factors, where relevant: the enterprise value of a portfolio company, the nature and realizable value of any collateral, the portfolio company’s ability to make payments and its earnings and discounted cash flows, the markets in which the portfolio company does business, comparisons to publicly traded securities, and changes in the interest rate environment and the credit markets generally that affect the price at which similar investments are made and other relevant factors. The primary method for determining enterprise value uses a multiple analysis whereby appropriate multiples are applied to the portfolio company’s net income before net interest expense, income tax expense, depreciation and amortization (“EBITDA”). A portfolio company’s EBITDA can include pro-forma adjustments for items such as acquisitions, divestitures, or expense reductions. The enterprise value analysis is performed to determine the value of equity investments and to determine if debt investments are credit impaired. If debt investments are credit impaired, the Company will use the enterprise value analysis or a liquidation basis analysis to determine fair value. For debt investments that are not determined to be credit impaired, the Company uses a market interest rate yield analysis to determine fair value. In addition, for certain debt investments, the Company bases its valuation on indicative bid and ask prices provided by an independent third-party pricing service. Bid prices reflect the highest price that the Company and others may be willing to pay. Ask prices represent the lowest price that the Company and others may be willing to accept. The Company generally uses the midpoint of the bid/ask range as its best estimate of fair value of such investment. Due to the inherent uncertainty of determining the fair value of Level 3 investments that do not have a readily available market value, the fair value of the investments may differ significantly from the values that would have been used had a ready market existed for such investments and may differ materially from the values that are ultimately received or settled. Further, such investments are generally subject to legal and other restrictions or otherwise are less liquid than publicly traded instruments. If the Company were required to liquidate a portfolio investment in a forced or liquidation sale, the Company could realize significantly less than the value at which such investment had previously been recorded. The Company’s investments are subject to market risk. Market risk is the potential for changes in the value due to market changes. Market risk is directly impacted by the volatility and liquidity in the markets in which the investments are traded.

On May 17, 2023, the Company’s sole shareholder approved the application of the reduced asset coverage requirements of Section 61(a)(2) of the 1940 Act and declined the Company’s offer to repurchase all of its outstanding common shares. As a result of such approval, effective as of May 18, 2023, the Company’s asset coverage requirement was reduced from 200% to 150%, or a ratio of total consolidated assets to outstanding indebtedness of 2:1 as compared to a maximum of 1:1 under the 200% asset coverage requirement under the 1940 Act. As of September 30, 2023, the Company’s asset coverage for borrowed amounts was 213.9%. 2023 Debt Securitization: Through October 26, 2027, all principal collections received on the underlying collateral may be used by the 2023 Issuer to purchase new collateral under the direction of the Investment Adviser, in its capacity as collateral manager of the 2023 Issuer, in accordance with the Company’s investment strategy and subject to customary conditions set forth in the documents governing the 2023 Debt Securitization, allowing the Company to maintain the initial leverage in the 2023 Debt Securitization.

Income Tax Disclosure [Abstract]
Federal Income Tax Matters	Note 7. Federal Income Tax Matters The Company intends to elect to be treated and intends to be subject to tax as a RIC under Subchapter M of the Code. As a result, the Company must distribute substantially all of its net taxable income each tax year as dividends to its shareholders. Accordingly, no provision for federal income tax has been made in the financial statements. Dividends from net investment income and distributions from net realized capital gains are determined in accordance with U.S. federal tax regulations, which may differ from amounts determined in accordance with GAAP and those differences could be material. These book-to-tax differences are either temporary or permanent in nature. Reclassifications due to permanent book-tax differences have no impact on net assets. The following permanent differences were reclassified for tax purposes among the components of net assets for the period from June 30, 2023 (commencement of operations) to September 30, 2023: ​ ​ ​ ​ ​ ​ Period from June 30, 2023 ​ ​ (commencement of operations) ​ ​ to September 30, 2023 Increase (decrease) in Paid in Capital in Excess of Par ​ $ (291) Increase (decrease) in Distributable Earnings (Losses) ​ 291 ​ Taxable income generally differs from net increase (decrease) in net assets resulting from operations for financial reporting purposes due to temporary and permanent differences in the recognition of income and expenses and generally excludes unrealized appreciation (depreciation) on investments transactions as investment gains and losses are not included in taxable income until they are realized. The following table reconciles net increase in net assets resulting from operations to taxable income for the period from June 30, 2023 (commencement of operations) to September 30, 2023: ​ ​ ​ ​ ​ ​ Period from June 30, 2023 ​ ​ (commencement of operations) ​ ​ to September 30, 2023 Net increase in net assets resulting from operations ​ $ 16,423 Net change in unrealized (appreciation) depreciation on investment transactions ​ 587 Other income not currently taxable ​ (43) Expenses not currently deductible ​ 291 Other deductions/losses for tax not book ​ (74) Other realized gain/loss differences ​ 43 Taxable income before deductions for distributions ​ $ 17,227 ​ The tax character of distributions paid during the period from June 30, 2023 (commencement of operations) to September 30, 2023 were as follows: ​ ​ ​ ​ ​ ​ Period from June 30, 2023 ​ ​ (commencement of operations) ​ ​ to September 30, 2023 Ordinary Income ​ $ 10,938 ​ The tax basis components of distributable earnings/(accumulated losses) and reconciliation to accumulated earnings/(deficit) on a book basis for the period from June 30, 2023 (commencement of operations) to September 30, 2023 were as follows: ​ ​ ​ ​ ​ ​ Period from June 30, 2023 ​ ​ (commencement of operations) ​ ​ to September 30, 2023 Undistributed ordinary income – tax basis ​ $ 6,289 Net unrealized appreciation (depreciation) on investments ​ (587) Other temporary differences ​ (5,414) Total accumulated earnings (loss) – book basis ​ $ 288 ​ Capital losses in excess of capital gains earned in a tax year may generally be carried forward and used to offset capital gains, subject to certain limitations. Capital losses incurred by the Company are not subject to expiration and retain their character as either short-term or long-term capital losses. As of September 30, 2023, the Company estimates that it will not have a capital loss carryforward available for use in subsequent tax years. For tax purposes, the Company may elect to defer any portion of a post-October capital loss or late-year ordinary loss to the first day of the following fiscal year. As of September 30, 2023, the Company did not elect to defer any ordinary losses, short-term capital losses and long-term capital losses. For the tax year ended September 30, 2023, the Company estimates taxable income in excess of the distributions made from such taxable income during the tax year, and therefore, the Company has elected to carry forward the excess for distribution to shareholders in the tax year ended September 30, 2024. The amount carried forward to tax year ended September 30, 2024 is estimated to be approximately $6,289 of ordinary income, although this amount will not be finalized until the September 30, 2023 tax returns are filed in 2024. As of September 30, 2023, the federal tax cost of investments was $1,179,576 resulting in estimated gross unrealized gains and losses of $3,080 and $4,023, respectively.

Net Assets	Note 3. Net Assets As of June 30, 2023, the Fund was beneficially owned 98% by GCP HS Fund and 2% by GCP CLO Sub. Profits and losses are allocated to the Beneficial Owners in proportion to their respective beneficial ownership percentage.	Note 10. Net Assets Share Issuances On April 27, 2023, an affiliate of the Investment Adviser purchased 2,000 shares of the Company’s Class F common shares (reclassified as Class I shares) at a purchase price of $25.00 per share. On June 14, 2023, the Company completed the Private Offering and entered into subscription agreements with the Private Offering Investors for total commitments of $650.3 million to purchase the Company’s Class F common shares. Following the completion of the Private Offering and prior to the commencement of the Public Offering, the Company’s Class F shares were reclassified as Class I shares. On June 30, 2023, the Company received the Private Offering subscription proceeds and issued 26,010,927.600 Class F common shares (reclassified as Class I shares) at a purchase price of $25.00 per share. In connection with its formation, the Company has the authority to issue an unlimited number of common shares of beneficial interest at $0.01 per share par value. The Company offers on a continuous basis up to $5.0 billion of common shares of beneficial interest pursuant to the Public Offering. The Company has applied for exemptive relief from the SEC that, if granted, will permit the Company to offer to sell any combination of three classes of common shares, Class S shares, Class D shares and Class I shares, through the Public Offering with a dollar value up to the maximum offering amount. There is no assurance, however, that the relief will be granted. The Company will accept purchase orders and hold investors’ funds in an interest-bearing escrow account until the Company receives purchase orders for at least 100 investors in such class and the Company’s Board has authorized the release of the funds in the escrow account. The share classes have different ongoing distribution and/or shareholder servicing fees. In connection with the Public Offering, the Company sells shares at an offering price per share as determined in accordance with a share pricing policy. Under such policy, in connection with each monthly closing on the sale of shares of Class S shares, Class D shares and Class I shares, the Board has authorized the Investment Adviser to establish a net offering price that it believes reflects a price per share that is no less than the then-current NAV per share. The following table summarizes the net offering price per share of Class I shares during the period from June 30, 2023 (commencement of operations) to September 30, 2023: ​ ​ ​ ​ ​ ​ Net Offering Price Per Share For the Month Ended ​ Class I July 31, 2023 ​ $ 25.00 August 31, 2023 ​ 25.05 September 30, 2023 ​ 25.00 ​ Distributions and Distribution Reinvestment The Board authorizes and declares monthly distribution amounts per share that are recorded by the Company on the record date.

Share Repurchase Program At the discretion of the Board, the Company intends to commence a share repurchase program in which the Company intends to repurchase, in each quarter, up to 5% of the NAV of the Company’s common shares outstanding as of the close of the previous calendar quarter. The Board may amend, suspend or terminate the share repurchase program if it deems such action to be in the best interest of shareholders. As a result, share repurchases may not be available each quarter. The Company intends to conduct such repurchase offers in accordance with the requirements of Rule 13e-4 promulgated under the Securities Exchange Act of 1934, as amended, and the 1940 Act. All shares purchased pursuant to the terms of each tender offer will be retired and thereafter will be authorized and unissued shares. Under the share repurchase program, to the extent the Company offers to repurchase shares in any particular quarter, it is expected to repurchase shares pursuant to tender offers on or around the last business day of the first month of such quarter using a purchase price equal to the NAV per share as of the last calendar day of the prior quarter, except that shares that have not been outstanding for at least one year will be repurchased at 98% of such NAV (an “Early Repurchase Deduction”). The one-year holding period is measured as of the subscription closing date immediately following the prospective repurchase date. The Early Repurchase Deduction will be retained by the Company for the benefit of remaining shareholders. During the period from June 30, 2023 (commencement of operations) to September 30, 2023, the Company did not repurchase any shares.

The availability of observable inputs can vary depending on the financial instrument and is affected by a wide variety of factors, including, for example, the type of product, whether the product is new, whether the product is traded on an active exchange or in the secondary market and the current market conditions. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for financial instruments classified as Level 3. Any changes to the valuation methodology are reviewed by management and the Company’s board of trustees (the “Board”) to confirm that the changes are appropriate. As markets change, new products develop and the pricing for products becomes more or less transparent, the Company will continue to refine its valuation methodologies. See Note 5. Fair Value Measurements for further description of fair value methodology.

Consolidation		Consolidation: Assets related to transactions that do not meet ASC Topic 860 requirements for accounting sale treatment are reflected in the Company’s Consolidated Statement of Financial Condition as investments. Those assets are owned by the 2023 Issuer, a special purpose entity, that is consolidated in the Company’s consolidated financial statements. The creditors of the special purpose entity have received security interests in such assets and such assets are not intended to be available to the creditors of GCRED (or any affiliate of GCRED).

Net assets and fair values are presented based on the applicable foreign exchange rates described above and fluctuations arising from the translation of assets and liabilities are included with the net change in unrealized appreciation (depreciation) on translation of assets and liabilities in foreign currencies on the Statement of Operations. Realized gains or losses arising from foreign currency transactions are reported as components of the net realized gain (loss) on foreign currency transactions on the Statement of Operations. Foreign security and currency transactions involve certain considerations and risks not typically associated with investing in U.S. companies. These risks include, but are not limited to, currency fluctuations and revaluations and future adverse political, social and economic developments, which could cause investments in foreign markets to be less liquid and prices more volatile than those of comparable U.S. companies or U.S. government securities.

Revenue recognition	Revenue recognition: Investments and related investment income: For investments with contractual payment-in-kind (“PIK”) interest, contractual interest is accrued, added to the principal balance and generally becomes due at maturity. For the period from June 8, 2023 (commencement of operations) to June 30, 2023, the Fund capitalized PIK interest of $205,621 into the principal balance of certain debt investments. Realized gains or losses on investments are measured by the difference between the net proceeds from the disposition and the amortized cost basis of investment, without regard to unrealized gains or losses previously recognized. The Fund reports the changes in fair value of investments that are measured at fair value as a component of the net change in unrealized appreciation (depreciation) on investments on the Statement of Operations. Non-accrual loans: Interest payments received on non-accrual loans are recognized as income or applied to principal depending upon management’s judgment. When the Fund receives principal payments on a non-accrual loan in an amount that exceeds the loan’s amortized cost, it may recognize the excess principal payment as interest income based on upon management’s judgement. Non-accrual loans are restored to accrual status when past due principal and interest is paid, and, in management’s judgment, payments are likely to remain current. As of June 30, 2023, the Fund had no portfolio company investments on non-accrual status.	Revenue recognition: Investments and related investment income: Loan origination fees, original issue discount and market discount or premium are capitalized, and the Company accretes or amortizes such amounts over the life of the loan as interest income. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, interest income included $1,196 of accretion of discounts. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, the Company received loan origination fees of $2,432. For investments with contractual payment-in-kind (“PIK”) interest, which represents contractual interest accrued and added to the principal balance that generally becomes due at maturity, the Company will not accrue PIK interest if the portfolio company valuation indicates that the PIK interest is not collectible. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, interest income included $601 of PIK interest and the Company capitalized PIK interest of $513 into the principal balance of certain debt investments. In addition, the Company generates revenue in the form of amendment, structuring or due diligence fees, fees for providing managerial assistance, consulting fees, administrative agent fees, and prepayment premiums on loans. The Company records these fees as fee income when earned. All other income is recorded into income when earned. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, fee income included no prepayment premiums. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, the Company received interest and fee income in cash, which excludes capitalized loan origination fees, in the amount of $14,403. Dividend income on equity securities is recorded as dividend income on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. The Company may have certain preferred equity securities in the portfolio that contain a PIK dividend provision that are accrued and recorded as income at the contractual rates, if deemed collectible. The accrued PIK and non-cash dividends are capitalized to the cost basis of the preferred equity security and are generally collected when redeemed by the issuer. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, the Company did not not Dividend income on common equity securities is recorded on the record date for private portfolio companies or on the ex-dividend date for publicly traded portfolio companies. Each distribution received from limited liability company (“LLC”) and limited partnership (“LP”) investments is 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 equity investments in LLCs and LPs as dividend income unless there are sufficient accumulated tax-basis earnings and profits in the LLC or LP prior to the distribution. Distributions that are classified as a return of capital are recorded as a reduction in the amortized cost basis of the investment.
Investment transactions		Investment transactions are accounted for on a trade-date basis. Realized gains or losses on investments are measured by the difference between the net proceeds from the disposition and the amortized cost basis of investment, without regard to unrealized gains or losses previously recognized. The Company reports current period changes in fair value of investments that are measured at fair value as a component of the net change in unrealized appreciation (depreciation) on investment transactions in the Consolidated Statement of Operations.

Dividends and distributions		Dividends and distributions: 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 shareholders, unless a shareholder elects to receive cash. As a result, if the Board authorizes and the Company declares a cash distribution, then shareholders who have not “opted out” of the DRIP will have their cash distribution automatically reinvested in additional shares of the Company’s common shares, rather than receiving the cash distribution. Shares issued under the DRIP will be issued at a price per share equal to the most recent net offering price per share for such shares at the time the distribution is payable.

Fair value measurements		The Company follows ASC Topic 820 for measuring fair value. Fair value is the price that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Where available, fair value is based on observable market prices or parameters, or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation models involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the assets or liabilities or market and the assets’ or liabilities’ complexity. The Company’s fair value analysis includes an analysis of the value of any unfunded loan commitments. Assets and liabilities are categorized for disclosure purposes based upon the level of judgment associated with the inputs used to measure their value. The valuation hierarchical levels are based upon the transparency of the inputs to the valuation of the asset or liability as of the measurement date. The three levels are defined as follows: Level 1: Level 2: Level 3: In certain cases, the inputs used to measure fair value fall into different levels of the fair value hierarchy. In such cases, an asset’s or a liability’s categorization within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. The Company assesses the levels of assets and liabilities at each measurement date, and transfers between levels are recognized on the actual date of the event or change in circumstances that caused the transfers. There were no transfers among Level 1, 2 and 3 of the fair value hierarchy for assets and liabilities during the period from June 30, 2023 (commencement of operations) to September 30, 2023. The following section describes the valuation techniques used by the Company to measure different assets and liabilities at fair value and includes the level within the fair value hierarchy in which the assets and liabilities are categorized. Investments Level 1 investments are valued using quoted market prices. Level 2 investments are valued using market consensus prices that are corroborated by observable market data and quoted market prices for similar assets and liabilities. Level 3 investments are valued at fair value as determined in good faith by the Board, based on input of management, the audit committee and independent valuation firms that have been engaged at the direction of the Board to assist in the valuation of each portfolio investment without a readily available market quotation at least once during a trailing twelve-month period under a valuation policy and a consistently applied valuation process. This valuation process is conducted at the end of each fiscal quarter, with approximately 25% (based on the number of portfolio companies) of the Company’s valuations of debt and equity investments without readily available market quotations subject to review by an independent valuation firm. As of September 30, 2023, $139,934 and $1,038,699 of investments were valued using Level 2 inputs and Level 3 inputs, respectively. As of September 30, 2023, all money market funds included in cash and cash equivalents and restricted cash and cash equivalents were valued using Level 1 inputs. When determining fair value of Level 3 debt and equity investments, the Company takes into account the following factors, where relevant: the enterprise value of a portfolio company, the nature and realizable value of any collateral, the portfolio company’s ability to make payments and its earnings and discounted cash flows, the markets in which the portfolio company does business, comparisons to publicly traded securities, and changes in the interest rate environment and the credit markets generally that affect the price at which similar investments are made and other relevant factors. The primary method for determining enterprise value uses a multiple analysis whereby appropriate multiples are applied to the portfolio company’s net income before net interest expense, income tax expense, depreciation and amortization (“EBITDA”). A portfolio company’s EBITDA can include pro-forma adjustments for items such as acquisitions, divestitures, or expense reductions. The enterprise value analysis is performed to determine the value of equity investments and to determine if debt investments are credit impaired. If debt investments are credit impaired, the Company will use the enterprise value analysis or a liquidation basis analysis to determine fair value. For debt investments that are not determined to be credit impaired, the Company uses a market interest rate yield analysis to determine fair value. In addition, for certain debt investments, the Company bases its valuation on indicative bid and ask prices provided by an independent third-party pricing service. Bid prices reflect the highest price that the Company and others may be willing to pay. Ask prices represent the lowest price that the Company and others may be willing to accept. The Company generally uses the midpoint of the bid/ask range as its best estimate of fair value of such investment. Due to the inherent uncertainty of determining the fair value of Level 3 investments that do not have a readily available market value, the fair value of the investments may differ significantly from the values that would have been used had a ready market existed for such investments and may differ materially from the values that are ultimately received or settled. Further, such investments are generally subject to legal and other restrictions or otherwise are less liquid than publicly traded instruments. If the Company were required to liquidate a portfolio investment in a forced or liquidation sale, the Company could realize significantly less than the value at which such investment had previously been recorded. The Company’s investments are subject to market risk. Market risk is the potential for changes in the value due to market changes. Market risk is directly impacted by the volatility and liquidity in the markets in which the investments are traded.

Selling agents will not charge such fees on Class I shares. Please consult your selling agent for additional information. (2) Under our share repurchase program, to the extent we offer to repurchase shares in any particular quarter, we expect to repurchase shares pursuant to tender offers on or around the last business day of the first month of such quarter using a purchase price equal to the NAV per share as of a Valuation Date. Shareholders should keep in mind that if they tender Common Shares in a tender offer with a Valuation Date that is within the 12 month period following the initial issue date of their tendered Common Shares, such Common Shares will be subject to an Early Repurchase Deduction. The one-year holding period is measured as of the subscription closing date immediately following the prospective repurchase date. The Early Repurchase Deduction may be waived in the case of repurchase requests arising from the death, divorce or qualified disability of the holder; in the event that a shareholder’s shares are repurchased because the shareholder has failed to maintain the $500 minimum account balance; or due to trade or operational error. The Early Repurchase Deduction will be retained by the Fund for the benefit of remaining shareholders.

For purposes of the Investment Advisory Agreement, net assets means our total assets less liabilities determined on a consolidated basis in accordance with GAAP. The base management fee referenced in the table above is annualized and based on actual amounts incurred during the period from June 30, 2023 (commencement of operations) to September 30, 2023 by GC Advisors in its capacity as investment adviser to us and collateral manager to the 2023 Issuer. The adjusted estimate of our annualized base management fee based on actual expenses for the period from June 30, 2023 (commencement of operations) to September 30, 2023 assumes net assets of $653 million and leverage of $572 million, which reflects our net assets and leverage as of September 30, 2023. GC Advisors, as collateral manager for our indirect, wholly owned, consolidated subsidiary, the 2023 Issuer, under a collateral management agreement (the “2023 Collateral Management Agreement”), is entitled to receive an annual fee in an amount equal to 0.35% of the principal balance of the portfolio loans held by the 2023 Issuer at the beginning of the collection period relating to each payment date, which is payable in arrears on each payment date. Under the 2023 Collateral Management Agreement, the term “collection period” relating to any payment date, refers to the period commencing on the tenth business day prior to the preceding payment date and ending on (but excluding) the tenth business day prior to such payment date. The collateral management fee described above is less than the base management fee payable under the Investment Advisory Agreement and is paid directly by the 2023 Issuer to GC Advisors and is offset against the management fees payable under the Investment Advisory Agreement. Accordingly, the 1.25% base management fee paid by us to GC Advisors under the Investment Advisory Agreement on our net assets, including assets indirectly held through the 2023 Issuer is reduced, on a dollar for dollar basis, by an amount equal to the 0.35% fee paid to GC Advisors by the 2023 Issuer. (4) We may have capital gains and investment income that could result in the payment of an incentive fee. The incentive fees, if any, are divided into two parts: ● The first part of the incentive fee is based on income, whereby we will pay the Investment Adviser quarterly in arrears 12.5% of our Pre-Incentive Fee Net Investment Income Returns (as defined below) for each calendar quarter, as adjusted for share issuances and repurchases, subject to a 5.0% annualized hurdle rate, with a catch-up. ● The second part of the incentive fee is based on realized capital gains, whereby we will pay the Investment Adviser at the end of each calendar year in arrears 12.5% of cumulative realized capital gains from inception through the end of such calendar year, computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis, less the aggregate amount of any previously paid incentive fee on capital gains. The incentive fee referenced in the table above is annualized and based on actual amounts of the income component of the incentive fee incurred during the period from June 30, 2023 (commencement of operations) to September 30, 2023. As of September 30, 2023, no amount was payable for the capital gains component under the Investment Advisory Agreement. (5) Subject to FINRA limitations on underwriting compensation, we will also pay the following shareholder servicing and/or distribution fees to the Managing Dealer on a monthly basis: (a) for Class S shares, a shareholder servicing and/or distribution fee equal to 0.85% per annum of the aggregate NAV for the Class S shares and (b) for Class D shares only, a shareholder servicing and/or distribution fee equal to 0.25% per annum of the aggregate NAV for the Class D shares. The distribution and servicing expenses borne by the participating brokers may be different from and substantially less than the amount of shareholder servicing and/or distribution fees charged. All or a portion of the shareholder servicing and/or distribution fee may be used to pay for sub-transfer agency, sub-accounting and certain other administrative services. The Fund also may pay for these sub-transfer agency, sub-accounting and certain other administrative services outside of the shareholder servicing and/or distribution fees and its Distribution and Servicing Plan. No shareholder servicing and/or distribution fees will be paid with respect to the Class I shares. In addition, as set forth in and pursuant to the Managing Dealer Agreement, we will pay the Managing Dealer certain fees for its services as Managing Dealer, which will be borne indirectly by all shareholders of the Fund. See “Plan of Distribution—Underwriting Compensation.” Such additional amounts are reflected in “Other Expenses.” The total amount that will be paid over time for underwriting compensation depends on the average length of time for which shares remain outstanding, the term over which such amount is measured and the performance of our investments. We will cease paying the shareholder servicing and/or distribution fee on the Class S shares and Class D shares on the earlier to occur of the following: (i) a listing of Class I shares, (ii) our merger or consolidation with or into another entity, or the sale or other disposition of all or substantially all of our assets or (iii) the date following the completion of the primary portion of this offering on which, in the aggregate, underwriting compensation from all sources in connection with this offering, including the shareholder servicing and/or distribution fee and other underwriting compensation, is equal to 10% of the gross proceeds from our primary offering. In addition, consistent with the exemptive relief the Fund has applied for that would allow us to offer multiple classes of shares, at the end of the month in which the Managing Dealer in conjunction with the transfer agent determines that total transaction or other fees, including upfront placement fees or brokerage commissions, and shareholder servicing and/or distribution fees paid with respect to the shares held in a shareholder’s account would exceed, in the aggregate, 10% of the gross proceeds from the sale of such shares (or a lower limit as determined by the Managing Dealer or the applicable selling agent), we will cease paying the shareholder servicing and/or distribution fee on the Class S shares and Class D shares in such shareholder’s account. Compensation paid with respect to the shares in a shareholder’s account will be allocated among each share such that the compensation paid with respect to each individual share will not exceed 10% of the offering price of such share. We may modify this requirement in a manner that is consistent with applicable exemptive relief. At the end of such month, the Class S shares or Class D shares in such shareholder’s account will convert into a number of Class I shares (including any fractional shares), with an equivalent aggregate NAV as such Class S or Class D shares. See “Plan of Distribution” and “Estimated Use of Proceeds.” The total underwriting compensation and total organization and offering expenses will not exceed 10% and 15%, respectively, of the gross proceeds from this offering. (6) Interest payments on borrowed funds is based on our cost of funds on our outstanding indebtedness for the period from June 30, 2023 (commencement of operations) to September 30, 2023, which consisted of $176.8 million of indebtedness outstanding under the SMBC Credit Facility and $395.5 million in notes issued through the 2023 Debt Securitization. For the period from June 30, 2023 (commencement of operations) to September 30, 2023, the annualized cost of funds for our total debt outstanding, which includes all interest, accretion of discounts, and amortization of debt issuance costs, was 7.87%. Debt issuance costs represent fees and other direct incremental costs incurred in connection with our debt facilities. These fees include a structuring and placement fee paid to SG Americas Securities, LLC for its services in connection with the initial structuring of the 2023 Debt Securitization and legal fees, accounting fees, rating agency fees and all other costs associated with the 2023 Debt Securitization. (7) “Other expenses” include, but are not limited to, expenses relating to and/or borne by the 2023 Issuer (formerly, the CLO Vehicle), 2023 CLO Depositor and GCRED Holdings (if any), accounting, legal and auditing fees, reimbursement of expenses to our Administrator, organization and offering expenses, underwriting compensation paid outside of the distribution and servicing fee described above and fees payable to our trustees, as discussed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” The amount presented in the table is annualized and based on actual amounts incurred during the period from June 30, 2023 (commencement of operations) to September 30, 2023. We have entered into an Expense Support and Conditional Reimbursement Agreement with the Investment Adviser. The Investment Adviser may elect to pay certain of our expenses on our behalf, including organization and offering expenses, provided that no portion of the payment will be used to pay any interest expense or shareholder servicing and/or distribution fees of the Fund. Any Expense Payment that the Investment Adviser has committed to pay must be paid by the Investment Adviser to us in any combination of cash or other immediately available funds no later than 45 days after such commitment was made in writing, and/or offset against amounts due from us to the Investment Adviser or its affiliates. If the Investment Adviser elects to pay certain of our expenses, the Investment Adviser will be entitled to reimbursement of such expenses from us if Available Operating Funds (as defined below) exceed the cumulative distributions accrued to the Fund’s shareholders. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Expenses—Expense Support and Conditional Reimbursement Agreement” for additional information regarding the Expense Support Agreement. Because the Investment Adviser’s obligation to pay certain of our expenses is voluntary, the table above does not reflect the impact of any expense support from the Investment Adviser. ​ Example:

Management Fee not based on Net Assets, Note [Text Block]	(3) The base management fee paid to our Investment Adviser is calculated at an annual rate of 1.25% of the value of our net assets as of the beginning of the first calendar day of the applicable quarter adjusted for share issuances and repurchases. For purposes of the Investment Advisory Agreement, net assets means our total assets less liabilities determined on a consolidated basis in accordance with GAAP. The base management fee referenced in the table above is annualized and based on actual amounts incurred during the period from June 30, 2023 (commencement of operations) to September 30, 2023 by GC Advisors in its capacity as investment adviser to us and collateral manager to the 2023 Issuer. The adjusted estimate of our annualized base management fee based on actual expenses for the period from June 30, 2023 (commencement of operations) to September 30, 2023 assumes net assets of $653 million and leverage of $572 million, which reflects our net assets and leverage as of September 30, 2023. GC Advisors, as collateral manager for our indirect, wholly owned, consolidated subsidiary, the 2023 Issuer, under a collateral management agreement (the “2023 Collateral Management Agreement”), is entitled to receive an annual fee in an amount equal to 0.35% of the principal balance of the portfolio loans held by the 2023 Issuer at the beginning of the collection period relating to each payment date, which is payable in arrears on each payment date. Under the 2023 Collateral Management Agreement, the term “collection period” relating to any payment date, refers to the period commencing on the tenth business day prior to the preceding payment date and ending on (but excluding) the tenth business day prior to such payment date. The collateral management fee described above is less than the base management fee payable under the Investment Advisory Agreement and is paid directly by the 2023 Issuer to GC Advisors and is offset against the management fees payable under the Investment Advisory Agreement. Accordingly, the 1.25% base management fee paid by us to GC Advisors under the Investment Advisory Agreement on our net assets, including assets indirectly held through the 2023 Issuer is reduced, on a dollar for dollar basis, by an amount equal to the 0.35% fee paid to GC Advisors by the 2023 Issuer.

General Description of Registrant [Abstract]
Investment Objectives and Practices [Text Block]	INVESTMENT OBJECTIVES AND STRATEGIES We were formed on May 13, 2022, as a Delaware statutory trust. We have elected to be regulated as a BDC under the 1940 Act. We also intend to elect to be treated, and intend to qualify annually thereafter, as a RIC under Subchapter M of the Code. As a BDC and a RIC, we will be required to comply with certain regulatory requirements. We were organized to make investments and generate current income and capital appreciation by investing primarily in privately originated and privately negotiated investments, predominantly through direct lending to U.S. private companies in the middle market and upper middle market in the form of one stop and other senior secured loans. GC Advisors structures these one stop loans as senior secured loans, and we obtain security interests in the assets of the portfolio company that serve as collateral in support of the repayment of these loans. This collateral often takes the form of first-priority liens on the assets of the portfolio company. In many cases, we are the sole lender or we, together with our affiliates, are the sole lenders of one stop loans, which can afford us additional influence over the borrower in terms of monitoring and, if necessary, remediating any underperformance. In this prospectus, the term “middle market” generally refers to companies having earnings before interest, taxes, depreciation and amortization, or EBITDA, of less than $100 million annually and the term “upper middle market” refers generally to companies having EBITDA of $100 million or greater annually. Our investment objective is to generate current income and capital appreciation. We will seek to meet our investment objective by: ● accessing the established loan origination channels developed by Golub Capital, a leading lender to U.S. middle market companies with over $60 billion in capital under management as of October 1, 2023; ● selecting liquid and illiquid credit investments of U.S. companies, and to a lesser extent, non-U.S. companies, in the middle market and upper middle market; ● partnering with experienced private equity firms, or sponsors, in many cases with whom Golub Capital has invested alongside in the past; ● implementing the disciplined underwriting standards of Golub Capital; and ● drawing upon the aggregate experience and resources of Golub Capital. Under normal circumstances, we will invest at least 80% of our total assets (net assets plus borrowings for investment purposes) directly or indirectly in private credit investments (loans, bonds and other credit and related instruments that are issued in private offerings or issued by private companies). Under normal circumstances, we expect that the majority of our portfolio will be directly or indirectly invested in privately originated and privately negotiated investments, predominantly through direct lending to U.S. private companies in the middle market and upper middle market in the form of one stop and other senior secured loans. We will also selectively invest in second lien and subordinated loans (including loans that rank senior only to a borrower’s equity securities and ranks junior to all of such borrower’s other indebtedness in priority of payment) of private companies. We may also invest in liquid credit instruments, including secured floating rate syndicated loans, securitized products and corporate bonds, and our portfolio may, but will not necessarily, initially be comprised of a greater percentage of such instruments than it will as our investment program matures, though the exact allocation may vary from time to time depending on market conditions and available investment opportunities. Our portfolio may also include equity interests such as preferred equity, debt investments accompanied by equity-related securities (including warrants) and, to a limited extent, common equity investments, which generally would be obtained as part of providing a broader financing solution. Under normal conditions, we expect to make investments that typically will have position sizes under 1% of our portfolio, on average. We expect to selectively invest more than 1% of capital in some of our portfolio companies and generally expect that the size of our individual investments will vary proportionately with the size of our capital base, particularly during the period prior to raising sufficient capital, which may result in larger individual investments when and if our capital base increases. We may invest in companies of any size or capitalization. We intend to primarily invest in U.S. middle market and upper middle market companies and, to the extent we invest in foreign companies, we intend to do so in accordance with the limits of the 1940 Act applicable to business development companies and only in jurisdictions with established legal frameworks and a history of respecting creditors rights as well as investment grade sovereign credit ratings, which generally includes countries that are members of the OECD such as the United Kingdom, countries that are members of the European Union, as well as Canada, Australia and Japan, among others. Subject to the limitations of the 1940 Act, we may invest in loans or other securities, the proceeds of which may refinance or otherwise repay debt or securities of companies whose debt is owned by other funds affiliated with Golub Capital. From time to time, we may co-invest with other funds affiliated with Golub Capital. See “Regulation.” We generally invest in securities that have been rated below investment grade by independent rating agencies or that would be rated below investment grade if they were rated. These securities, which are often referred to as “junk,” have predominantly speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal. In addition, many of our debt investments have floating interest rates that reset on a periodic basis and typically do not fully pay down principal prior to maturity, which could increase our risk of losing part or all of our investment. We intend to finance our investments with borrowed money. The amount of leverage that we employ will depend on GC Advisors’ and our board of trustees’ assessment of market and other factors at the time of any proposed borrowing. While we intend to target a leverage ratio of 0.85x to 1.25x debt-to-equity, this limitation will not prevent us from incurring additional leverage or otherwise exceeding such leverage ratio to the full extent permissible under the 1940 Act, including during periods when we are experiencing unusual market volatility or other unexpected conditions. We could issue senior debt securities to banks, insurance companies and other lenders, and/or issue unsecured debt or notes through one or more wholly-owned CLOs. Under the terms of our Declaration of Trust, the board of trustees may authorize us to issue preferred shares in one or more classes or series without shareholder approval, to the extent permitted by the 1940 Act. In addition, investment in leveraged companies involves a number of significant risks. Leveraged companies in which we invest could have limited financial resources and could be unable to meet their obligations under their debt securities that we hold. We may engage in hedging transactions to the limited extent such transactions are permitted under the 1940 Act and applicable commodities laws. We could, for example, use instruments such as interest rate swaps, caps, collars and floors and, if we were to invest in foreign securities, we could use instruments such as forward contracts or currency options in currencies selected to hedge against fluctuations in the relative values of our portfolio positions from changes in currency exchange rates and market interest rates. We could also, for example, borrow under a credit facility in currencies selected to minimize our foreign currency exposure. There can be no assurance any hedging strategy we employ will be successful. Our investments are subject to a number of risks. See “Risk Factors.” Our Investment Adviser and Administrator Our investment activities are managed by our Investment Adviser, GC Advisors. GC Advisors is responsible for sourcing potential investments, conducting research and due diligence on prospective investments and equity sponsors, analyzing investment opportunities, structuring our investments and monitoring our investments and portfolio companies on an ongoing basis. GC Advisors was organized in September 2008 and is a registered investment adviser under the Advisers Act. Under our Investment Advisory Agreement, or the Investment Advisory Agreement, with GC Advisors, we pay GC Advisors a base management fee and an incentive fee for its services. GC Advisors is an affiliate of Golub Capital and pursuant to the Staffing Agreement, Golub Capital LLC makes experienced investment professionals available to GC Advisors and provides access to the senior investment personnel of Golub Capital LLC and its affiliates. The Staffing Agreement provides GC Advisors with access to deal flow generated by Golub Capital LLC and its affiliates in the ordinary course of their businesses and commits the members of GC Advisors’ investment committee to serve in that capacity. As our investment adviser, GC Advisors is obligated to allocate investment opportunities among us and its other clients fairly and equitably over time in accordance with its allocation policy. See “Conflicts of Interest” below. However, there can be no assurance that such opportunities will be allocated to us fairly or equitably in the short-term or over time. GC Advisors seeks to capitalize on the significant deal origination, credit underwriting, due diligence, investment structuring, execution, portfolio management and monitoring experience of Golub Capital LLC’s investment professionals. Golub Capital LLC, our Administrator and an affiliate of GC Advisors, provides the administrative services necessary for us to operate. See “Investment Advisory Agreement and Administration Agreement — Administration Agreement” for a discussion of the fees and expenses (subject to the review and approval of our Independent Trustees) we are required to reimburse to the Administrator.

Market Opportunity We intend to pursue an investment strategy focused on investing primarily in newly originated first lien, senior secured, floating rate loans in U.S. middle market companies in industries that we believe are resistant to recession. We find the middle market attractive for the following reasons: Target Market. Specialized Lending Requirements ​ Demand for Debt Capital Competition from Bank Lenders. Market Environment: 2 ​ ​ 2 Standard & Poor’s “High-End Middle-Market Lending Review Q4 2021” — New-issue first-lien yield-to-maturity. Middle-market loans have, on average, generated higher yields in comparison to large corporate loans based on data starting in June 2005. ​ Golub Capital Strengths Deep, Experienced Management Team Leading U.S. Debt Platform Provides Access to Proprietary Relationship-Based Deal Flow Disciplined Investment and Underwriting Process Regimented Credit Monitoring Concentrated Middle Market Focus ● middle market companies are generally less leveraged than large companies and, we believe, offer more attractive investment returns in the form of upfront fees, prepayment penalties and higher interest rates; ● middle market issuers are more likely to have simple capital structures; ● carefully structured covenant packages enable middle market lenders to take early action to remediate poor financial performance; and ● middle market lenders can undertake thorough due diligence investigations prior to investment. Investment Criteria/Guidelines Our investment objective is to generate current income and capital appreciation by investing primarily in senior secured and one stop loans to U.S. middle market and upper middle market companies in industries we believe are resistant to recessions. We seek to generate strong risk-adjusted net returns by assembling a portfolio of investments across a broad range of industries and private equity sponsors. We primarily target U.S. middle-market companies controlled by private equity investors that require capital for growth, acquisitions, recapitalizations, refinancings and leveraged buyouts. We seek to have a portfolio of first-lien, senior secured loans to borrowers believed to be insulated from the effects of the novel coronavirus, or COVID-19, pandemic and/or in what we believe are recession resistant industries. We also make opportunistic loans to independently owned and publicly held middle-market companies. We seek to partner with strong management teams executing long-term growth strategies. Target businesses will typically exhibit some or all of the following characteristics: ● annual EBITDA of less than $150.0 million; ● sustainable leading positions in their respective markets; ● scalable revenues and operating cash flow; ● experienced management teams with successful track records; ● insulation from the effects of the COVID-19 pandemic; ● stable, predictable cash flows with low technology and market risks; ● a substantial equity cushion in the form of capital ranking junior to our investment provided by a middle market private equity sponsor; ● low capital expenditures requirements; ● a North American base of operations; ● strong customer relationships; ● products, services or distribution channels having distinctive competitive advantages; ● defensible niche strategy or other barriers to entry; and ● demonstrated growth strategies. While we believe that the criteria listed above are important in identifying and investing in prospective portfolio companies, not all of these criteria will be met by each prospective portfolio company. Investment Process Overview We view our investment process as consisting of four distinct phases described below: Origination Golub Capital has principal lending offices in Chicago, New York, London and San Francisco. Each of Golub Capital’s originators maintains long-standing customer relationships and is responsible for covering a specified target market. We believe those originators’ strength and breadth of relationships across a wide range of markets generate numerous financing opportunities, which we believe enables GC Advisors to be highly selective in recommending investments to us. Underwriting ● a thorough review of historical and pro forma financial information; ● on-site visits; ● interviews with management and employees; ● a review of loan documents and material contracts; ● third-party “quality of earnings” accounting due diligence; ● when appropriate, background checks on key managers and research relating to the company’s business, industry, markets, customers, suppliers, products and services and competitors; and ● the commission of third-party market studies when appropriate. The following chart illustrates the stages of Golub Capital’s evaluation and underwriting process: ILLUSTRATIVE DEAL EVALUATION PROCESS Execution. Monitoring. As part of the monitoring process, GC Advisors regularly assesses the risk profile of each of our investments and rates each of them based on an internal system developed by Golub Capital and its affiliates. This system is not generally accepted in our industry or used by our competitors. It is based on the following categories, which we refer to as GC Advisors’ internal performance ratings: Internal Performance Ratings ​ ​ ​ Rating Definition 5 ​ Involves the least amount of risk in our portfolio. The borrower is performing above expectations, and the trends and risk factors are generally favorable. 4 ​ Involves an acceptable level of risk that is similar to the risk at the time of origination. The borrower is generally performing as expected, and the risk factors are neutral to favorable. 3 ​ Involves a borrower performing below expectations and indicates that the loan’s risk has increased somewhat since origination. The borrower could be out of compliance with debt covenants; however, loan payments are generally not past due. 2 ​ Involves a borrower performing materially below expectations and indicates that the loan’s risk has increased materially since origination. In addition to the borrower being generally out of compliance with debt covenants, loan payments could be past due (but generally not more than 180 days past due). 1 ​ Involves a borrower performing substantially below expectations and indicates that the loan’s risk has substantially increased since origination. Most or all of the debt covenants are out of compliance and payments are substantially delinquent. Loans rated 1 are not anticipated to be repaid in full and we will reduce the fair market value of the loan to the amount we anticipate will be recovered. ​ Our internal performance ratings do not constitute any rating of investments by a nationally recognized statistical rating organization or represent or reflect any third-party assessment of any of our investments. For any investment rated 1, 2 or 3, GC Advisors increases its monitoring intensity and prepares regular updates for the investment committee, summarizing current operating results and material impending events and suggesting recommended actions. GC Advisors monitors and, when appropriate, changes the internal performance ratings assigned to each investment in our portfolio. In connection with our valuation process, GC Advisors and our board of trustees review these internal performance ratings on a quarterly basis. Investment Committee The purpose of GC Advisors’ investment committee, which is comprised of officers of GC Advisors, is to evaluate and approve all of our investments, subject to the oversight of our board of trustees. The investment committee process is intended to bring the diverse experience and perspectives of the committee’s members to the analysis and consideration of each investment. The investment committee currently consists of Lawrence E. Golub, David B. Golub, Andrew H. Steuerman, Gregory W. Cashman, Spyro G. Alexopoulos, Marc C. Robinson, Robert G. Tuchscherer and Jason J. Van Dussen. The investment committee serves to provide investment consistency and adherence to our core investment philosophy and policies. The investment committee also determines appropriate investment sizing and suggests ongoing monitoring requirements. Investment teams and investment committees responsible for an area of investment may include investment professionals and senior management from among one or more of the Investment Adviser and its affiliates. In addition to reviewing investments, investment committee meetings serve as a forum to discuss credit views and outlooks. Potential transactions and deal flow are reviewed on a regular basis. Members of the investment team are encouraged to share information and credit views with the investment committee early in their analysis. We believe this process improves the quality of the analysis and assists the deal team members to work more efficiently. Each transaction is presented to the investment committee in a formal written report. Each investment opportunity generally receives the unanimous approval of the investment committee. Each member of the investment committee performs a similar role for other investment funds, accounts or other investment vehicles, collectively referred to as accounts, sponsored or managed by Golub Capital and its affiliates. Broadly Syndicated Loans Investment Team GC Advisors’ broadly syndicated loans investment team (“BSL Team”) is generally responsible for managing the Fund’s broadly syndicated loans where Golub Capital does not act as lead arranger, joint lead arranger or co-manager (“BSLs”). The Fund’s BSL investments may be comprised of debt obligations with various public credit ratings, although we expect such investments primarily to be comprised of obligations below investment grade quality. Investment Structure Once GC Advisors determines that a prospective portfolio company is suitable for investment, GC Advisors typically works with the private equity sponsor, if applicable, the management of that company and its other capital providers to structure our investment. GC Advisors negotiates with these parties to agree on how our investment should be structured relative to other capital in the portfolio company’s capital structure. GC Advisors structures our investments, which typically have maturities of three to seven years, as follows: Senior Secured Loans One Stop Loans One stop loans include loans to technology companies undergoing strong growth due to new services, increased adoption and/or entry into new markets. We refer to loans to these companies as recurring revenue loans. Other targeted characteristics of recurring revenue businesses include strong customer revenue retention rates, a diversified customer base and backing from growth equity or venture capital firms. In some cases, the borrower’s high revenue growth is supported by a high level of discretionary spending. As part of the underwriting of such loans and consistent with industry practice, we adjust our characterization of the earnings of such borrowers for a reduction or elimination of such discretionary expenses, if appropriate. Second Lien Loans Subordinated Loans Second lien loans and subordinated loans are generally more volatile than first lien, senior secured loans and involve a greater risk of loss of principal. In addition, the PIK feature of many subordinated loans, which effectively operates as negative amortization of loan principal, increases credit risk exposure over the life of the loan. Subordinated loans are more likely to include a PIK feature. Equity Investments Our equity co-investments will typically include customary “tag-along” and/or “drag-along” rights that will permit or require us to participate in a sale of such equity co-investments at such time as the majority owners, not GC Advisors, determine. GC Advisors tailors the terms of each investment to the facts and circumstances of the transaction and the prospective portfolio company, negotiating a structure that protects our rights and manages our risk while creating incentives for the portfolio company to achieve its business plan and improve its operating results. GC Advisors seeks to limit the downside potential of our investments by: ● selecting investments that we believe have a very low probability of loss; ● requiring a total return on our investments that we believe will compensate us appropriately for credit risk; and ● negotiating covenants in connection with our investments that afford our portfolio companies as much flexibility in managing their businesses as possible, consistent with the preservation of our capital. Such restrictions could include affirmative and negative covenants, default penalties, lien protection, change of control provisions and board rights. We expect to hold most of our investments to maturity or repayment, but we may sell some of our investments earlier if a liquidity event occurs, such as a sale, recapitalization or worsening of the credit quality of the portfolio company. Investments We seek to create a portfolio that includes primarily one stop and other senior secured loans by investing in the securities of middle market companies. We invest primarily in first lien, senior secured loans in middle market companies in industries that we believe are recession resistant. In addition, we seek to have a portfolio of first-lien, senior secured loans to borrowers believed to be insulated from the effects of the novel coronavirus, or COVID-19, pandemic. Under normal conditions, we expect to make investments that typically will have position sizes under 1% of our portfolio, on average. We expect to selectively invest more than 1% of capital in some of our portfolio companies and generally expect that the size of our individual investments will vary proportionately with the size of our capital base, particularly during the period prior to raising sufficient capital, which may result in larger individual investments when and if our capital base increases. We may invest in companies of any size or capitalization. Managerial Assistance As a business development company, we offer, and must provide upon request, managerial assistance to our portfolio companies. This assistance could involve monitoring the operations of our portfolio companies, participating in board and management meetings, consulting with and advising officers of portfolio companies and providing other organizational and financial guidance. The Administrator or an affiliate of the Administrator provides such managerial assistance on our behalf to portfolio companies that request this assistance. We could receive fees for these services and reimburse the Administrator or an affiliate of the Administrator, as applicable, for its allocated costs in providing such assistance, subject to the review and approval by our board of trustees, including our Independent Trustees. Competition Our primary competitors in providing financing to middle market companies include public and private funds, other business development companies, commercial and investment banks, commercial financing companies and, to the extent they provide an alternative form of financing, private equity and hedge funds. Many of our competitors are substantially larger and have considerably greater financial, technical, and marketing resources than we do. For example, we believe some competitors have access to funding sources that are not available to us. In addition, some of our competitors have higher risk tolerances or different risk assessments, which could allow them to consider a wider variety of investments and establish more relationships than us. Furthermore, many of our competitors are not subject to the regulatory restrictions that the 1940 Act imposes on us as a business development company or to the source-of-income, asset diversification and distribution requirements we must satisfy to qualify for and maintain our treatment as a RIC. We use the expertise of the investment professionals of Golub Capital and its affiliates to which we have access to assess investment risks and determine appropriate pricing for our investments in portfolio companies. In addition, the relationships of the senior members of Golub Capital and its affiliates enable us to learn about, and compete effectively for, financing opportunities with attractive middle market companies in the industries in which we invest. See “Risk Factors — Risks Relating to our Business and Structure — We operate in a highly competitive market for investment opportunities, which could reduce returns and result in losses Temporary Investments Pending investments in other types of qualifying assets, as described above, our investments could consist of cash, cash equivalents, U.S. government securities, repurchase agreements and high-quality debt investments that mature in one year or less from the date of investment, which we refer to, collectively, as temporary investments, so that 70% of our assets are qualifying assets or temporary investments. Typically, we will invest in U.S. Treasury bills or in repurchase agreements, so long as the agreements are fully collateralized by cash or securities issued by the U.S. government or its agencies. A repurchase agreement involves the purchase by an investor, such as us, of a specified security and the simultaneous agreement by the seller to repurchase it at an agreed-upon future date and at a price that is greater than the purchase price by an amount that reflects an agreed-upon interest rate. There is no percentage restriction on the proportion of our assets that could be invested in such repurchase agreements. However, if more than 25% of our total assets constitute repurchase agreements from a single counterparty, we would generally not meet the diversification tests described in Section 851(b)(3) of the Code in order to qualify as a RIC for U.S. federal income tax purposes. Accordingly, we do not intend to enter into repurchase agreements with a single counterparty in excess of this limit. Administration We do not have any direct employees, and our day-to-day investment operations are managed by GC Advisors. Our business and affairs are managed under the direction of our board of trustees. We have a chief executive officer, chief financial officer, chief operating officer, chief compliance officer, managing directors and an associate director, and to the extent necessary, our board of trustees can elect to appoint additional officers going forward. Our officers are officers and/or employees of Golub Capital LLC, an affiliate of GC Advisors, and our allocable portion of the cost of our chief financial officer and chief compliance officer and their respective staffs is paid by us pursuant to the administration agreement, or the Administration Agreement, with the Administrator. See “Investment Advisory Agreement and Administration Agreement — Administration Agreement.”
Risk Factors [Table Text Block]	RISK FACTORS Investing in our Common Shares involves a number of significant risks. Before you invest in our Common Shares, you should be aware of various risks, including those described below. The risks set out below are known material risks but not the only risks we face. Additional risks and uncertainties not presently known to us or not presently deemed material by us could also impair our operations and performance. If any of the following events occur, our business, financial condition, results of operations and cash flows could be materially and adversely affected. In such case, our NAV could decline, and you could lose all or part of your investment. The risk factors described below are the principal risk factors associated with an investment in us as well as those factors generally associated with an investment company with investment objectives, investment policies, capital structure or trading markets similar to ours. In addition to the other information contained in this prospectus, you should consider carefully the following information before making an investment in our Common Shares. Risks Related to Our Business and Structure We are a relatively new company and have limited prior operating history. The Fund is a non-diversified, closed-end management investment company that has elected to be regulated as a BDC with limited prior operating history. As a result, prospective investors have no track record or history on which to base their investment decision. We are subject to all of the business risks and uncertainties associated with any new business, including the risk that we will not achieve our investment objective, that we will not qualify or maintain our qualification to be treated as a RIC, and that the value of your investment could decline substantially or become worthless. Further, GC Advisors has not previously offered a non-traded business development company. While we believe that the past professional experiences of GC Advisors’ investment team, including investment and financial experience of the GC Advisors’ senior management, will increase the likelihood that the GC Advisors will be able to manage the Fund successfully, there can be no assurance that this will be the case. We are subject to risks associated with the current interest rate environment and to the extent we use debt to finance our investments, changes in interest rates will affect our cost of capital and net investment income. To the extent we borrow money or issue debt securities or preferred stock to make investments, our net investment income will depend, in part, upon the difference between the rate at which we borrow funds or pay interest or dividends on such debt securities or preferred stock and the rate at which we invest these funds. In addition, many of our debt investments and borrowings have floating interest rates that reset on a periodic basis, and many of our investments are subject to interest rate floors. As a result, a change in market interest rates could have a material adverse effect on our net investment income. In periods of rising interest rates, our cost of funds will increase because the interest rates on the amounts borrowed under our credit facilities or certain other financing arrangements are typically floating, which could reduce our net investment income to the extent any debt investments have fixed interest rates, and the interest rate on investments with an interest rate floor above current levels will not increase until interest rates exceed the applicable floor. We can use interest rate risk management techniques in an effort to limit our exposure to interest rate fluctuations. Such techniques could include various interest rate hedging activities to the extent permitted by the 1940 Act and applicable commodities laws. These activities could limit our ability to participate in the benefits of lower interest rates with respect to the hedged borrowings. Adverse developments resulting from changes in interest rates or hedging transactions could have a material adverse effect on our business, financial condition and results of operations. You should also be aware that a rise in the general level of interest rates typically will lead to higher interest rates applicable to our debt investments, which could result in an increase of the amount of incentive fees payable to GC Advisors. In addition, a decline in the prices of the debt we own could adversely affect our NAV. Also, an increase in interest rates available to investors could make an investment in our Common Shares less attractive if we are not able to increase our distribution rate, which could reduce the value of our Common Shares. We operate in a highly competitive market for investment opportunities, which could reduce returns and result in losses. A number of entities compete with us to make the types of investments that we plan to make, and we believe that recent market trends, including sustained periods of low interest rates, have increased the number of competitors seeking to invest in loans to private, middle market and upper middle market companies in the United States. We compete with public and private funds, commercial and investment banks, commercial financing companies and, to the extent they provide an alternative form of financing, private equity and hedge funds. Many of our competitors are substantially larger and have considerably greater financial, technical and marketing resources than we do. For example, we believe some of our competitors could have access to funding sources that are not available to us. In addition, some of our competitors could have higher risk tolerances or different risk assessments, which could allow them to consider a wider variety of investments and establish more relationships than us. Furthermore, many of our competitors are not subject to the regulatory restrictions that the 1940 Act imposes on us as a business development company or the source of income, asset diversification and distribution requirements we must satisfy to qualify for and maintain our treatment as a RIC. The competitive pressures we face could have a material adverse effect on our business, financial condition, results of operations and cash flows. As a result of this competition, we can provide no assurance that we will be able to take advantage of attractive investment opportunities that arise from time to time, and we can provide no assurance that we will be able to identify and make investments that are consistent with our investment objective. An excess of the amount of capital in the private debt markets and overall competition for loans could result in short term returns for us that are lower than our long-term targets. In the event these conditions continue for an extended amount of time, they could have a material adverse effect on our business, financial condition and results of operations. Identifying, structuring and consummating investments involves competition among capital providers and market and transaction uncertainty. GC Advisors can provide no assurance that it will be able to identify a sufficient number of suitable investment opportunities or to avoid prepayment of existing investments to satisfy our investment objectives, including as necessary to effectively structure credit facilities or other forms of leverage. The loan origination market is very competitive, which can result in loan terms that are more favorable to borrowers, and conversely less favorable to lenders, such as lower interest rates and fees, weaker borrower financial and other covenants, borrower rights to cure defaults, and other terms more favorable to borrowers than current or historical norms. Increased competition could cause us to make more loans that are “cov-lite” in nature and, in a distressed scenario, there can be no assurance that these loans will retain the same value as loans with a full package of covenants. As a result of these conditions, the market for leveraged loans could become less advantageous than expected for us, and this could increase default rates, decrease recovery rates or otherwise harm our returns. The risk of prepayment is also higher in the current competitive environment if borrowers are offered more favorable terms by other lenders. The financial markets have experienced substantial fluctuations in prices and liquidity for leveraged loans. Any further disruption in the credit and other financial markets could have substantial negative effects on general economic conditions, the availability of required capital for companies and the operating performance of such companies. These conditions also could result in increased default rates and credit downgrades, and affect the liquidity and pricing of the investments made by us. Conversely, periods of economic stability and increased competition among capital providers could increase the difficulty of locating investments that are desirable for us. With respect to the investments we make, we do not seek to compete based primarily on the interest rates we offer, and we believe that some of our competitors could make loans with interest rates that will be lower than the rates we offer. In the secondary market for acquiring existing loans, we compete generally on the basis of pricing terms. With respect to all investments, we could lose some investment opportunities if we do not match our competitors’ pricing, terms and structure. However, if we match our competitors’ pricing, terms and structure, we could experience decreased net interest income, lower yields and increased risk of credit loss. We will also compete for investment opportunities with accounts managed or sponsored by GC Advisors or its affiliates. Although GC Advisors allocates opportunities in accordance with its allocation policy, allocations to such other accounts will reduce the amount and frequency of opportunities available to us and thus not necessarily be in the best interests of us and our security holders. Moreover, the performance of investments will not be known at the time of allocation. Covenant-lite loans may expose us to different risks, including with respect to liquidity, ability to restructure loans, credit risks and less protective loan documentation, than is the case with loans that contain financial maintenance covenants. Certain loans in our portfolio may consist of “covenant-lite” loans. Such loans may not require the borrower to maintain debt service or other financial ratios and do not include terms which allow the lender to monitor the performance of the borrower and declare a default if certain criteria are breached. Ownership of covenant-lite loans may expose us to different risks, including with respect to liquidity, ability to restructure loans, credit risks and less protective loan documentation, than is the case with loans that contain financial maintenance covenants. Rising interest rates could affect the value of our investments and make it more difficult for portfolio companies to make periodic payments on their loans. Interest rate risk refers to the risk of market changes in interest rates. Interest rate changes affect the value of debt. In general, rising interest rates will negatively impact the price of fixed rate debt, and falling interest rates will have a positive effect on price. Adjustable rate debt also reacts to interest rate changes in a similar manner, although generally to a lesser degree. Interest rate sensitivity is generally larger and less predictable in debt with uncertain payment or prepayment schedules. Further, rising interest rates make it more difficult for borrowers to repay debt, which could increase the risk of payment defaults. Any failure of one or more portfolio companies to repay or refinance its debt at or prior to maturity or the inability of one or more portfolio companies to make ongoing payments following an increase in contractual interest rates could have a material adverse effect on our business, financial condition, results of operations and cash flows. We are subject to risks associated with the transition away from LIBOR. Following their publication on June 30, 2023, no settings of the London Interbank Offered Rate (“LIBOR”) continue to be published on a representative basis and publication of many non-U.S. dollar LIBOR settings has been entirely discontinued. On July 29, 2021, the U.S. Federal Reserve System, in conjunction with the Alternative Reference Rates Committee, a steering committee comprised of large U.S. financial institutions, formally recommended replacing U.S.-dollar LIBOR with the Secured Overnight Financing Rate (“SOFR”), a new index calculated by short-term repurchase agreements, backed by Treasury securities. In April 2018, the Bank of England began publishing its proposed alternative rate, the Sterling Overnight Index Average (“SONIA”). Each of SOFR and SONIA significantly differ from LIBOR, both in the actual rate and how it is calculated. Further, on March 15, 2022, the Consolidation Appropriations Act of 2022, which includes the Adjustable Interest Rate (LIBOR) Act (“LIBOR Act”), was signed into law in the United States. This legislation establishes a uniform benchmark replacement process for certain financial contracts that mature after June 30, 2023 that do not contain clearly defined or practicable LIBOR fallback provisions. The legislation also creates a safe harbor that shields lenders from litigation if they choose to utilize a replacement rate recommended by the Board of Governors of the Federal Reserve. In addition, the U.K. Financial Conduct Authority (“FCA”), which regulates the publisher of LIBOR (ICE Benchmark Administration) has announced that it will require the continued publication of the one-, three- and six-month tenors of U.S.-dollar LIBOR on a non-representative synthetic basis until the end of September 2024, which may result in certain non-U.S. law-governed contracts and U.S. law-governed contracts not covered by the federal legislation remaining on synthetic U.S.-dollar LIBOR until the end of this period. Although the transition process away from LIBOR has become increasingly well-defined (e.g. the LIBOR Act now provides a uniform benchmark replacement for certain LIBOR-based instruments in the United States), the transition process is complex and it could cause a disruption in the credit markets generally and could have adverse impacts on our business financial condition and results of operations, including, among other things, increased volatility or illiquidity in markets for instruments that continue to rely on LIBOR or which have been transitioned away from LIBOR to a different rate like SOFR and, in any case, could result in a reduction in the value of certain investments held by the Fund. We are dependent upon GC Advisors for our success and upon its access to the investment professionals and partners of Golub Capital and its affiliates. We do not have any internal management capacity or employees. We rely on GC Advisors to manage and conduct our affairs and make all investment decisions. Subject to the oversight of our board of trustees, GC Advisors has sole discretion in originating, structuring, negotiating, purchasing, financing and eventually divesting our investments, and our investors will not be able to evaluate for themselves the merits of particular investments prior to us making such investments. We depend on the diligence, skill and network of business contacts of the senior investment professionals of GC Advisors to achieve our investment objective. GC Advisors’ investment committee, which consists of two members of our board of trustees and additional employees of Golub Capital LLC, provides oversight over our investment activities. We also cannot assure you that we will replicate the historical results achieved by members of the investment committee, and we caution you that our investment returns could be substantially lower than the returns achieved by them in prior periods. We expect that GC Advisors will evaluate, negotiate, structure, close and monitor our investments in accordance with the terms of the Investment Advisory Agreement. We can offer no assurance, however, that the senior investment professionals of GC Advisors will continue to provide investment advice to us. If these individuals do not maintain their existing relationships with Golub Capital LLC and its affiliates and do not develop new relationships with other sources of investment opportunities, we can provide no assurance that GC Advisors or its affiliates will be able to identify appropriate replacements or grow our investment portfolio. The loss of any member of GC Advisors’ investment committee or of other senior investment professionals of GC Advisors and its affiliates would limit our ability to achieve our investment objective and operate as we anticipate. This could have a material adverse effect on our financial condition, results of operations and cash flows. The Staffing Agreement provides that Golub Capital LLC makes available to GC Advisors experienced investment professionals and provides access to the senior investment personnel of Golub Capital LLC for purposes of evaluating, negotiating, structuring, closing and monitoring our investments. We are not a party to the Staffing Agreement and cannot assure you that Golub Capital LLC will fulfill its obligations under the agreement. If Golub Capital LLC fails to perform, we cannot assure you that GC Advisors will enforce the Staffing Agreement, that such agreement will not be terminated by either party or that we will continue to have access to the investment professionals of Golub Capital LLC and its affiliates or their information and deal flow. Our business model depends to a significant extent upon strong referral relationships with sponsors and investing in companies backed by private equity sponsors. Any inability of GC Advisors to maintain or develop these relationships, or the failure of these relationships to generate investment opportunities, could adversely affect our business. GC Advisors is highly dependent on relationships with private equity sponsors in connection with the sourcing of investments. If private equity sponsors find new sources of debt capital that are more advantageous to them, or if GC Advisors suffers reputational harm such that it becomes a less attractive source of capital for private equity sponsors, GC Advisors could have difficulty finding and sourcing new middle market debt investments. Private equity sponsors could experience financial distress, which could be related or unrelated to the portfolio companies to which we have exposure. Once in financial distress, such sponsors likely would be unable to provide the same level of managerial, operating or financial support to such portfolio companies, resulting in an increased risk of default or inability to repay remaining principal at maturity. From time to time, we expect to have direct or indirect exposure to companies controlled by private equity sponsors in which the sponsors have completed one or more dividend recapitalizations, thereby allowing the private equity sponsor to substantially reduce or eliminate its net investment in an underlying portfolio company. These investments generally present different investment characteristics to us than investments where a private equity sponsor retains a significant net contributed capital position in the company. These investments could experience a higher rate of default. Even when a default does not occur, private equity sponsors could be less willing to provide ongoing financial, managerial or operating support to a portfolio company after it has received one or more capital distributions on its investment. We believe that purchase price multiples of companies (as measured by the price paid by a private equity sponsor to purchase a company divided by the company’s trailing twelve-month earnings) to which we have direct or indirect exposure are close to all-time highs. When considering the appropriate amount of financing to provide a prospective borrower, GC Advisors considers the value cushion as measured by the difference between the enterprise value of the company and the total amount of financing. If market purchase price multiples decline or if a portfolio company experiences financial distress, the value cushion supporting our investment could deteriorate and the investment could become impaired, resulting in losses for us. The risk of such losses for us are greater during periods when purchase price multiples are close to all-time highs. We can provide no assurance that we will be able to replicate the historical results achieved by other entities managed or sponsored by members of GC Advisors’ investment committee, or by GC Advisors or its affiliates. Investors are cautioned that past investment performance of similar portfolios and other investment vehicles managed by GC Advisors or its affiliates is not indicative of how we will perform. Our investments could differ from some existing accounts and funds that are or have been sponsored or managed by members of GC Advisors’ investment committee, GC Advisors or affiliates of GC Advisors. Investors in our securities are not acquiring an interest in any accounts that are or have been sponsored or managed by members of GC Advisors’ investment committee, GC Advisors or affiliates of GC Advisors. We will often co-invest in portfolio investments with other accounts sponsored or managed by members of GC Advisors’ investment committee, GC Advisors or its affiliates. Such investments are subject to regulatory limitations and approvals by trustees who are not “interested persons,” as defined in the 1940 Act. We can offer no assurance, however, that we will obtain such approvals or develop opportunities that comply with such limitations. We also cannot assure you that we will replicate the historical results achieved by us or by members of the investment committee, and we caution you that our investment returns could be substantially lower than the returns achieved in prior periods. Additionally, all or a portion of the prior results were achieved in particular market conditions that might never be repeated. Moreover, current or future market volatility and regulatory uncertainty can have an adverse impact on our future performance. Our financial condition, results of operations and cash flows depend on our ability to manage our business effectively. Our ability to achieve our investment objective depends on our ability to manage our business and to grow. This depends, in turn, on GC Advisors’ ability to identify, invest in and monitor companies that meet our investment criteria. The achievement of our investment objectives on a cost-effective basis depends upon GC Advisors’ execution of our investment process, its ability to provide competent, attentive and efficient services to us and, to a lesser extent, our access to financing on acceptable terms. GC Advisors has substantial responsibilities under the Investment Advisory Agreement, as well as responsibilities in connection with the management of other accounts sponsored or managed by GC Advisors, members of GC Advisors’ investment committee or the Administrator. The personnel of the Administrator and its affiliates could be called upon to provide managerial assistance to our portfolio companies. These activities could distract them or slow our rate of investment. Any failure to manage our business and our future growth effectively could have a material adverse effect on our business, financial condition, results of operations and cash flows. There are significant potential conflicts of interest as a result of our arrangements with GC Advisors and its affiliates and GC Advisors’ investment committee that could affect our investment returns. As a result of our arrangements with GC Advisors and its affiliates and GC Advisors’ investment committee, there will be times when GC Advisors or such persons have interests that differ from those of our security holders, giving rise to a conflict of interest, many of which are described in the following risk factors. GC Advisors attempts to identify, monitor and mitigate conflicts of interest. Further, GC Advisors has implemented policies and procedures reasonably designed to ensure its clients are treated fairly and equitably over time. GC Advisors believes that these factors, together with Golub Capital’s commitment to put investors first, effectively mitigate the risks associated with such conflicts of interest. However, it can be difficult to ensure that conflicts of interest do not adversely affect us. There are conflicts related to the obligations of GC Advisors’ investment committee, GC Advisors or its affiliates have to other clients and conflicts related to fees and expenses of such other clients. The members of GC Advisors’ investment committee serve as officers, trustees or principals of entities that operate in the same or a related line of business as we do or of accounts sponsored or managed by GC Advisors or its affiliates. Currently, our trustees and certain of our officers also serve as trustees and officers of GBDC, GBDC 3, GDLC, GBDC 4 and GDLCU, each a closed-end, non-diversified management investment company that has also elected to be regulated as a business development company under the 1940 Act. Similarly, GC Advisors and its affiliates manage other clients with similar or competing investment objectives. GC Advisors’ management team will share its time and attention between us and other investment vehicles and accounts. Neither we nor any investor in us unaffiliated with GC Advisors will have any rights in or to independent ventures of GC Advisors or its affiliates or in the income or profits derived therefrom. GC Advisors does not expect to have any dedicated personnel who spend all or substantially all of their time managing our investing activities. In serving in these multiple capacities, GC Advisors and its personnel have obligations to other clients or investors in those entities, the fulfillment of which could conflict with the best interests of us or our shareholders. Economic disruption and uncertainty precipitated by certain events, including, for example, public health crises such as the COVID-19 pandemic, could require GC Advisors and its affiliates to devote additional time and focus to existing portfolio companies in which other funds and accounts managed by GC Advisors and its affiliates hold investments. The allocation of time and focus by personnel of GC Advisors and its affiliates to existing portfolio company investments held by other funds and accounts could reduce the time that such individuals have to spend on our investing activities. Our investment objective overlaps with the investment objectives of other affiliated accounts. For example, GC Advisors and its affiliates currently manage GBDC, GBDC 3, GDLC, GBDC 4, GDLCU and multiple private funds and separate accounts that pursue an investment strategy similar to or overlapping with ours, some of which will seek additional capital from time to time. We compete with these and other accounts sponsored or managed by GC Advisors and its affiliates for capital and investment opportunities. As a result, GC Advisors and its affiliates face conflicts in the allocation of investment opportunities among us and other accounts advised by or affiliated with GC Advisors and, in certain circumstances, in the timing of the sale of an investment. Certain of these accounts provide for higher management or incentive fees, allow GC Advisors to recover greater expense reimbursements or overhead allocations, and/or permit GC Advisors and its affiliates to receive higher origination and other transaction fees, all of which could contribute to this conflict of interest and create an incentive for GC Advisors to favor such other accounts. For example, the 1940 Act restricts GC Advisors from receiving more than a 1% fee in connection with loans that we acquire, or originate, a limitation that does not exist for certain other accounts. GC Advisors seeks to allocate investment opportunities among eligible accounts in a manner that is fair and equitable over time and consistent with its allocation policy. However, we can offer no assurance that such opportunities will be allocated to us fairly or equitably in the short-term or over time, and there can be no assurance that we will be able to participate in all investment opportunities that are suitable to us. Furthermore, because allocations under GC Advisors’ allocation policy are based on total capital of the relevant investing funds, including us, we expect to receive smaller allocations relative to larger accounts, including accounts that can incur material amounts of leverage, which could have a material adverse effect on our business, financial condition, results of operations and cash flows during such ramp-up period. With respect to the sale of investments, the sale of an investment by one account advised by GC Advisors or its affiliates could potentially adversely affect the market value of the interests in such investment that continue to be held by other accounts, including us. GC Advisors’ investment committee, GC Advisors or its affiliates could, from time to time, possess material non-public information, limiting our investment discretion. Principals of GC Advisors and its affiliates and members of GC Advisors’ investment committee could serve as directors of, or in a similar capacity with, companies in which we invest, the securities of which are purchased or sold on our behalf. In the event that material non-public information is obtained with respect to such companies, or we become subject to trading restrictions under the internal trading policies of those companies or as a result of applicable law or regulations, we could be prohibited for a period of time from purchasing or selling the securities of such companies, and this prohibition could have an adverse effect on us. Our management and incentive fee structure creates incentives for GC Advisors that are not fully aligned with the interests of our shareholders and could induce GC Advisors to make certain investments, including speculative investments. In the course of our investing activities, we pay management and incentive fees to GC Advisors. We pay to GC Advisors an incentive fee that is based on the performance of our portfolio and an annual base management fee that is based on the value of our net assets as of the beginning of the first business day of the month. Because the incentive fee is based on the performance of our portfolio, GC Advisors may be incentivized to make investments on our behalf that are riskier or more speculative than would be the case in the absence of such compensation arrangement. The way in which the incentive fee is determined may also encourage GC Advisors to use leverage to increase the return on our investments. Our compensation arrangements could therefore result in our making riskier or more speculative investments than would otherwise be the case. This could result in higher investment losses, particularly during cyclical economic downturns. Additionally, the incentive fee payable by us to GC Advisors could create an incentive for GC Advisors to cause us to realize capital gains or losses that are not in the best interests of us or our shareholders. Under the incentive fee structure, GC Advisors benefits when we recognize capital gains and, because GC Advisors determines when an investment is sold, GC Advisors controls the timing of the recognition of such capital gains. Our board of trustees is charged with protecting our shareholders’ interests by monitoring how GC Advisors addresses these and other conflicts of interest associated with its management services and compensation. The part of the management and incentive fees payable to GC Advisors that relates to our net investment income is computed and paid on income that includes interest income that has been accrued but not yet received in cash, such as market discount, debt instruments with payment-in-kind (“PIK”) interest, preferred shares with PIK dividends, zero coupon securities, and other deferred interest instruments. This compensation arrangement creates an incentive for GC Advisors to make investments on our behalf that are riskier or more speculative, including debt financings that provide for deferred interest, rather than current cash payments of interest. Under these investments, we accrue the interest over the life of the investment but do not receive the ca

Security Obligations of Ownership [Text Block]	DESCRIPTION OF OUR SHARES The following description is based on relevant portions of Delaware law and on our Declaration of Trust and bylaws. This summary is not necessarily complete, and we refer you to Delaware law, our Declaration of Trust and our bylaws for a more detailed description of the provisions summarized below. General The terms of the Declaration of Trust authorize an unlimited number of Common Shares of any class, par value $0.01 per share, of which 26,292,010.889 Class I shares were outstanding as of November 22, 2023, and an unlimited number of shares of preferred shares, par value $0.01 per share. The Declaration of Trust provides that the board of trustees may classify or reclassify any unissued Common Shares into one or more classes or series of Common Shares or preferred shares by setting or changing the preferences, conversion or other rights, voting powers, restrictions, or limitations as to dividends, qualifications, or terms or conditions of redemption of the shares. There is currently no market for our Common Shares, and we can offer no assurances that a market for our shares will develop in the future. We do not intend for the shares offered under this prospectus to be listed on any national securities exchange. There are no outstanding options or warrants to purchase our shares. No shares have been authorized for issuance under any equity compensation plans. Under the terms of our Declaration of Trust, shareholders shall be entitled to the same limited liability extended to shareholders of private Delaware for profit corporations formed under the Delaware General Corporation Law, 8 Del. C. § 100, et. seq. Our Declaration of Trust provides that no shareholder shall be liable for any debt, claim, demand, judgment or obligation of any kind of, against or with respect to us by reason of being a shareholder, nor shall any shareholder be subject to any personal liability whatsoever, in tort, contract or otherwise, to any person in connection with the Fund’s assets or the affairs of the Fund by reason of being a shareholder. None of our shares are subject to further calls or to assessments, sinking fund provisions, obligations of the Fund or potential liabilities associated with ownership of the security (not including investment risks). In addition, except as may be provided by the board of trustees in setting the terms of any class or series of Common Shares, no shareholder shall be entitled to exercise appraisal rights in connection with any transaction. Outstanding Securities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amount Held ​ Amount ​ ​ ​ ​ by Fund ​ Outstanding ​ ​ Amount ​ for its ​ as of Title of Class Authorized Account November 22, 2023 Class S ​ Unlimited ​ — ​ — Class D Unlimited — — Class I Unlimited — 26,292,010.889 ​ Common Shares Under the terms of our Declaration of Trust, all Common Shares will have equal rights as to voting and, when they are issued, will be duly authorized, validly issued, fully paid and nonassessable. Dividends and distributions may be paid to the holders of our Common Shares if, as and when authorized by our board of trustees and declared by us out of funds legally available therefore. Except as may be provided by our board of trustees in setting the terms of classified or reclassified shares, our Common Shares will have no preemptive, exchange, conversion, appraisal or redemption rights and will be freely transferable, except where their transfer is restricted by federal and state securities laws or by contract and except that, in order to avoid the possibility that our assets could be treated as “plan assets,” we may require any person proposing to acquire Common Shares to furnish such information as may be necessary to determine whether such person is a benefit plan investor or a controlling person, restrict or prohibit transfers of such shares or redeem any outstanding shares for such price and on such other terms and conditions as may be determined by or at the direction of the board of trustees. In the event of our liquidation, dissolution or winding up, each share of our Common Shares would be entitled to share pro rata in all of our assets that are legally available for distribution after we pay all debts and other liabilities and subject to any preferential rights of holders of our preferred shares, if any preferred shares are outstanding at such time. Subject to the rights of holders of any other class or series of shares, each share of our Common Shares will be entitled to one vote on all matters submitted to a vote of shareholders, including the election of trustees. Except as may be provided by the board of trustees in setting the terms of classified or reclassified shares, and subject to the express terms of any class or series of preferred shares, the holders of our Common Shares will possess exclusive voting power. There will be no cumulative voting in the election of trustees. Subject to the special rights of the holders of any class or series of preferred shares to elect trustees, each trustee will be elected by a plurality of the votes cast with respect to such trustee’s election except in the case of a “contested election” (as defined in our bylaws), in which case trustees will be elected by a majority of the votes cast in the contested election of trustees. Pursuant to our Declaration of Trust, our board of trustees may amend the bylaws to alter the vote required to elect trustees. Class S Shares No upfront selling commissions are paid for sales of any Class S shares, however, if you purchase Class S shares from certain financial intermediaries, they may directly charge you transaction or other fees, including upfront placement fees or brokerage commissions, in such amount as they may determine, provided that selling agents limit such charges to a 3.5% cap on the net offering price for Class S shares. We pay the Managing Dealer selling commissions over time as a shareholder servicing and/or distribution fee with respect to our outstanding Class S shares equal to 0.85% per annum of the aggregate NAV of our outstanding Class S shares, including any Class S shares issued pursuant to our distribution reinvestment plan. The shareholder servicing and/or distribution fees are paid monthly in arrears. The Managing Dealer reallows (pays) all or a portion of the shareholder servicing and/or distribution fees to participating brokers and servicing brokers for ongoing shareholder services performed by such brokers, and will waive shareholder servicing and/or distribution fees to the extent a broker is not eligible to receive it for failure to provide such services. Class D Shares No upfront selling commissions are paid for sales of any Class D shares, however, if you purchase Class D shares from certain financial intermediaries, they may directly charge you transaction or other fees, including upfront placement fees or brokerage commissions, in such amount as they may determine, provided that selling agents limit such charges to a 1.5% cap on the net offering price for Class D shares. We pay the Managing Dealer selling commissions over time as a shareholder servicing and/or distribution fee with respect to our outstanding Class D shares equal to 0.25% per annum of the aggregate NAV of all our outstanding Class D shares, including any Class D shares issued pursuant to our distribution reinvestment plan. The shareholder servicing and/or distribution fees are paid monthly in arrears. The Managing Dealer reallows (pays) all or a portion of the shareholder servicing and/or distribution fees to participating brokers and servicing brokers for ongoing shareholder services performed by such brokers, and will waive shareholder servicing and/or distribution fees to the extent a broker is not eligible to receive it for failure to provide such services. Class D shares are generally available for purchase in this offering only (1) through fee-based programs, also known as wrap accounts, that provide access to Class D shares, (2) through participating brokers that have alternative fee arrangements with their clients to provide access to Class D shares, (3) through transaction/ brokerage platforms at participating brokers, (4) through certain registered investment advisers, (5) through bank trust departments or any other organization or person authorized to act in a fiduciary capacity for its clients or customers or (6) by other categories of investors that we name in an amendment or supplement to this prospectus. Class I Shares No upfront selling commissions or shareholder servicing and/or distribution fees are paid for sales of any Class I shares and financial intermediaries will not charge you transaction or other such fees on Class I Shares. Class I shares are generally available for purchase in this offering only (1) through fee-based programs, also known as wrap accounts, that provide access to Class I shares, (2) by endowments, foundations, pension funds and other institutional investors, (3) through participating brokers that have alternative fee arrangements with their clients to provide access to Class I shares, (4) through certain registered investment advisers, (5) by our executive officers and trustees and their immediate family members, as well as officers and employees of the Investment Adviser, Golub Capital or other affiliates and their immediate family members, and joint venture partners, consultants and other service providers or (6) by other categories of investors that we name in an amendment or supplement to this prospectus. In certain cases, where a holder of Class S or Class D shares exits a relationship with a participating broker for this offering and does not enter into a new relationship with a participating broker for this offering, such holder’s shares may be exchanged into an equivalent NAV amount of Class I shares. Class F Shares No Class F shares will be issued or sold in this offering. Other Terms of Common Shares We will cease paying the shareholder servicing and/or distribution fees on the Class S shares and Class D shares on the earlier to occur of the following: (i) a listing of Class I shares, (ii) our merger or consolidation with or into another entity, or the sale or other disposition of all or substantially all of our assets or (iii) the date following the completion of the primary portion of this offering on which, in the aggregate, underwriting compensation from all sources in connection with this offering, including the shareholder servicing and/or distribution fees and other underwriting compensation, is equal to 10% of the gross proceeds from our primary offering. In addition, consistent with the exemptive relief the Fund has applied for that would allow us to offer multiple classes of shares, at the end of the month in which the Managing Dealer in conjunction with the transfer agent determines that total transaction or other fees, including upfront placement fees or brokerage commissions, and shareholder servicing and/or distribution fees paid with respect to the shares held in a shareholder’s account would exceed, in the aggregate, 10% of the gross proceeds from the sale of such shares (or a lower limit as determined by the Managing Dealer or the applicable selling agent), we will cease paying the shareholder servicing and/or distribution fees on the Class S shares and Class D shares in such shareholder’s account. Compensation paid with respect to the shares in a shareholder’s account will be allocated among each share such that the compensation paid with respect to each individual share will not exceed 10% of the offering price of such share. We may modify this requirement in a manner that is consistent with applicable exemptive relief. At the end of such month, the Class S shares or Class D shares in such shareholder’s account will convert into a number of Class I shares (including any fractional shares), with an equivalent aggregate NAV as such Class S or Class D shares. In addition, immediately before any liquidation, dissolution or winding up, each Class S share and Class D share will automatically convert into a number of Class I shares (including any fractional shares) with an equivalent NAV as such share. Preferred Shares This offering does not include an offering of preferred shares. However, under the terms of the Declaration of Trust, our board of trustees may authorize us to issue preferred shares in one or more classes or series without shareholder approval, to the extent permitted by the 1940 Act. The board of trustees has the power to fix the preferences, conversion and other rights, voting powers, restrictions, limitations as to dividends and other distributions, qualifications and terms and conditions of redemption of each class or series of preferred shares. We do not currently anticipate issuing preferred shares in the near future. In the event we issue preferred shares, we will make any required disclosure to shareholders. We will not offer preferred shares to the Investment Adviser or our affiliates except on the same terms as offered to all other shareholders. Preferred shares could be issued with terms that would adversely affect the shareholders, provided that we may not issue any preferred shares that would limit or subordinate the voting rights of holders of our Common Shares. Preferred shares could also be used as an anti-takeover device through the issuance of shares of a class or series of preferred shares with terms and conditions which could have the effect of delaying, deferring or preventing a transaction or a change in control. Every issuance of preferred shares will be required to comply with the requirements of the 1940 Act. The 1940 Act requires, among other things, that: (1) immediately after issuance and before any dividend or other distribution is made with respect to Common Shares and before any purchase of Common Shares is made, such preferred shares together with all other senior securities must not exceed an amount equal to 50% of our total assets after deducting the amount of such dividend, distribution or purchase price, as the case may be, and (2) the holders of shares of preferred shares, if any are issued, must be entitled as a class voting separately to elect two trustees at all times and to elect a majority of the trustees if distributions on such preferred shares are in arrears by two full years or more. Certain matters under the 1940 Act require the affirmative vote of the holders of at least a majority of the outstanding shares of preferred shares (as determined in accordance with the 1940 Act) voting together as a separate class. For example, the vote of such holders of preferred shares would be required to approve a proposal involving a plan of reorganization adversely affecting such securities. The issuance of any preferred shares must be approved by a majority of our Independent Trustees not otherwise interested in the transaction, who will have access, at our expense, to our legal counsel or to independent legal counsel. Limitation on Liability of Trustees and Officers; Indemnification and Advance of Expenses Delaware law permits a Delaware statutory trust to include in its declaration of trust a provision to indemnify and hold harmless any trustee or beneficial owner or other person from and against any and all claims and demands whatsoever. Our Declaration of Trust provides that our trustees will not be liable to us or our shareholders for monetary damages for breach of fiduciary duty as a trustee to the fullest extent permitted by Delaware law. Our Declaration of Trust provides for the indemnification of any person to the full extent permitted, and in the manner provided, by Delaware law. In accordance with the 1940 Act, we will not indemnify certain persons for any liability to which such persons would be subject by reason of such person’s willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office. Pursuant to our Declaration of Trust and subject to certain exceptions described therein, we will indemnify and, without requiring a preliminary determination of the ultimate entitlement to indemnification, pay or reimburse reasonable expenses in advance of final disposition of a proceeding to (i) any individual who is a present or former Trustee or officer of the Fund and who is made or threatened to be made a party to the proceeding by reason of his or her service in that capacity or (ii) any individual who, while a Trustee or officer of the Fund and at the request of the Fund, serves or has served as a trustee, officer, partner or trustee of any corporation, partnership, joint venture, trust, employee benefit plan or other enterprise and who is made or threatened to be made a party to the proceeding by reason of his or her service in that capacity (each such person, an “Indemnitee”), in each case to the fullest extent permitted by Delaware law. Notwithstanding the foregoing, we will not provide indemnification for any loss, liability or expense arising from or out of an alleged violation of federal or state securities laws by an Indemnitee unless (i) there has been a successful adjudication on the merits of each count involving alleged securities law violations, (ii) such claims have been dismissed with prejudice on the merits by a court of competent jurisdiction, or (iii) a court of competent jurisdiction approves a settlement of the claims against the Indemnitee and finds that indemnification of the settlement and the related costs should be made and the court considering the request for indemnification has been advised of the position of the SEC and of the published position of any state securities regulatory authority in which securities were offered or sold as to indemnification for violations of securities laws. We will not indemnify an Indemnitee against any liability or loss suffered by such Indemnitee unless (i) the Fund determines in good faith that the course of conduct that caused the loss or liability was in the best interest of the Fund, (ii) the Indemnitee was acting on behalf of or performing services for the Fund, (iii) such liability or loss was not the result of (A) negligence or misconduct, in the case that the party seeking indemnification is a Trustee (other than an Independent Trustee), officer, employee, controlling person or agent of the Fund, or (B) gross negligence or willful misconduct, in the case that the party seeking indemnification is an Independent Trustee, and (iv) such indemnification or agreement to hold harmless is recoverable only out of assets of the Fund and not from the shareholders. In addition, the Declaration of Trust permits the Fund to advance reasonable expenses to an Indemnitee, and we will do so in advance of final disposition of a proceeding (a) if the proceeding relates to acts or omissions with respect to the performance of duties or services on behalf of the Fund, (b) the legal proceeding was initiated by a third party who is not a shareholder or, if by a shareholder of the Fund acting in his or her capacity as such, a court of competent jurisdiction approves such advancement and (c) upon the Fund’s receipt of (i) a written affirmation by the trustee or officer of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification by the Fund and (ii) a written undertaking by him or her or on his or her behalf to repay the amount paid or reimbursed by the Fund, together with the applicable legal rate of interest thereon, if it is ultimately determined that the standard of conduct was not met. Delaware Law and Certain Declaration of Trust Provisions Organization and Duration We were formed in Delaware on May 13, 2022, and will remain in existence until dissolved in accordance with our Declaration of Trust or pursuant to Delaware law. Purpose Under the Declaration of Trust, we are permitted to engage in any business activity that lawfully may be conducted by a statutory trust organized under Delaware law and, in connection therewith, to exercise all of the rights and powers conferred upon us pursuant to the agreements relating to such business activity. Our Declaration of Trust contains provisions that could make it more difficult for a potential acquirer to acquire us by means of a tender offer, proxy contest or otherwise. Our board of trustees may, without shareholder action, authorize the issuance of shares in one or more classes or series, including preferred shares; our board of trustees may, without shareholder action, amend our Declaration of Trust to increase the number of our Common Shares, of any class or series, that we will have authority to issue; and our Declaration of Trust provides that, while we do not intend to list our shares on any securities exchange, if any class of our shares is listed on a national securities exchange, our board of trustees will be divided into three classes of trustees serving staggered terms of three years each. These provisions are expected to discourage certain coercive takeover practices and inadequate takeover bids and to encourage persons seeking to acquire control of us to negotiate first with our board of trustees. We believe that the benefits of these provisions outweigh the potential disadvantages of discouraging any such acquisition proposals because, among other things, the negotiation of such proposals may improve their terms. Sales and Leases to the Fund Our Declaration of Trust provides that, unless otherwise permitted by the 1940 Act or applicable guidance or exemptive relief of the SEC, except as otherwise permitted under the 1940 Act, we may not purchase or lease assets in which the Investment Adviser or any of its affiliates have an interest unless all of the following conditions are met: (a) the transaction is fully disclosed to the shareholders in a prospectus or in a periodic report; and (b) the assets are sold or leased upon terms that are reasonable to us and at a price not to exceed the lesser of cost or fair market value as determined by an independent expert. However, the Investment Adviser may purchase assets in its own name (and assume loans in connection) and temporarily hold title, for the purposes of facilitating the acquisition of the assets, the borrowing of money, obtaining financing for us, or the completion of construction of the assets, so long as all of the following conditions are met: (i) the assets are purchased by us at a price no greater than the cost of the assets to the Investment Adviser; (ii) all income generated by, and the expenses associated with, the assets so acquired will be treated as belonging to us; and (iii) there are no other benefits arising out of such transaction to the Investment Adviser apart from compensation otherwise permitted by the Omnibus Guidelines, as adopted by the NASAA. Sales and Leases to our Investment Adviser, Trustees or Affiliates Our Declaration of Trust provides that, unless otherwise permitted by the 1940 Act or applicable guidance or exemptive relief of the SEC, we may not sell assets to the Investment Adviser or any of its affiliates unless such sale is approved by the holders of a majority of our outstanding Common Shares. Our Declaration of Trust also provides that we may not lease assets to the Investment Adviser or any affiliate thereof unless all of the following conditions are met: (a) the transaction occurs at the formation of the Fund and is fully disclosed to the shareholders in a prospectus or in a periodic report; and (b) the terms of the transaction are fair and reasonable to us. Loans Our Declaration of Trust provides that, except for the advancement of indemnification funds, no loans, credit facilities, credit agreements or otherwise may be made by us to the Investment Adviser or any of its affiliates. Commissions on Financing, Refinancing or Reinvestment Our Declaration of Trust provides that, unless otherwise permitted by the 1940 Act or applicable guidance or exemptive relief of the SEC, we generally may not pay, directly or indirectly, a commission or fee to the Investment Adviser or any of its affiliates in connection with the reinvestment of cash available for distribution, available reserves, or the proceeds of the resale, exchange or refinancing of assets. Lending Practices Our Declaration of Trust provides that, with respect to financing made available to us by the Investment Adviser, the Investment Adviser may not receive interest in excess of the lesser of the Investment Adviser’s cost of funds or the amounts that would be charged by unrelated lending institutions on comparable loans for the same purpose. The Investment Adviser may not impose a prepayment charge or penalty in connection with such financing and the Investment Adviser may not receive points or other financing charges. In addition, the Investment Adviser will be prohibited from providing financing to us with a term in excess of 12 months. Number of Trustees; Vacancies; Removal Our Declaration of Trust provides that the number of trustees will be set by our board of trustees in accordance with our bylaws. Our bylaws provide that a majority of our entire board of trustees may at any time increase or decrease the number of trustees. Our Declaration of Trust provides that the number of trustees generally may not be less than three. Except as otherwise required by applicable requirements of the 1940 Act and as may be provided by our board of trustees in setting the terms of any class or series of preferred shares, pursuant to an election under our Declaration of Trust, any and all vacancies on our board of trustees may be filled only by the affirmative vote of a majority of the remaining trustees in office, even if the remaining trustees do not constitute a quorum, and any trustee elected to fill a vacancy will serve for the remainder of the full term of the trustee for whom the vacancy occurred and until a successor is elected and qualified, subject to any applicable requirements of the 1940 Act. Our Declaration of Trust provides that a trustee may be removed only for cause and only by a majority of the remaining trustees (or in the case of the removal of a trustee that is not an interested person, a majority of the remaining trustees that are not interested persons) followed by the holders of at least seventy-five percent (75%) of the shares then entitled to vote in an election of such trustee. Our Declaration of Trust provides that, notwithstanding the foregoing provision, any trustee may be removed with or without cause upon the vote of a majority of then-outstanding shares. Our board of trustees is comprised of a total of seven members of our board of trustees, five of whom are Independent Trustees. Our Declaration of Trust provides that a majority of our board of trustees must be Independent Trustees except for a period of up to 60 days after the death, removal or resignation of an Independent Trustee pending the election of his or her successor. Each trustee will hold office until his or her successor is duly elected and qualified. While we do not intend to list our shares on any securities exchange, if any class of our shares is listed on a national securities exchange, our board of trustees will be divided into three classes of trustees serving staggered terms of three years each. Action by Shareholders Our bylaws provide that shareholder action can be taken at an annual meeting or a special meeting of shareholders. The shareholders will only have voting rights as required by the 1940 Act or as otherwise provided for in the Declaration of Trust. The Fund will hold annual meetings. Special meetings may be called by the trustees and certain of our officers, and will be limited to the purposes for any such special meeting set forth in the notice thereof. In addition, our Declaration of Trust provides that, subject to the satisfaction of certain procedural and informational requirements by the shareholders requesting the meeting, a special meeting of shareholders will be called by our secretary upon the written request of shareholders entitled to cast 10% or more of the votes entitled to be cast at the meeting. The secretary shall provide all shareholders, within ten days after receipt of said request, written notice either in person or by mail of the date, time and location of such requested special meeting and the purpose of the meeting. Any special meeting called by such shareholders is required to be held not less than fifteen nor more than 60 days after notice is provided to shareholders of the special meeting. These provisions will have the effect of significantly reducing the ability of shareholders being able to have proposals considered at a meeting of shareholders. With respect to special meetings of shareholders, only the business specified in our notice of the meeting may be brought before the meeting. Nominations of persons for election to the board of trustees at a special meeting may be made only (1) pursuant to our notice of the meeting, (2) by the board of trustees or (3) provided that the board of trustees has determined that trustees will be elected at the meeting, by a shareholder who is entitled to vote at the meeting and who has complied with the advance notice provisions of the Declaration of Trust. Our Declaration of Trust also provides that, subject to the provisions of any class or series of shares then outstanding and the mandatory provisions of any applicable laws or regulations or other provisions of the Declaration of Trust, the following actions may be taken by the shareholders, without concurrence by our board of trustees or the Investment Adviser, upon a vote by the holders of more than 50% of the outstanding shares entitled to vote to: ● modify the Declaration of Trust; ● remove the Investment Adviser or appoint a new investment adviser; ● dissolve the Fund; ● sell all or substantially all of our assets other than in the ordinary course of business; or ● remove any trustee with or without cause (provided the aggregate number of trustees after such removal shall not be less than the minimum required by the Declaration of Trust). The purpose of requiring shareholders to give us advance notice of nominations and other business is to afford our board of trustees a meaningful opportunity to consider the qualifications of the proposed nominees and the advisability of any other proposed business and, to the extent deemed necessary or desirable by our board of trustees, to inform shareholders and make recommendations about such qualifications or business, as well as to provide a more orderly procedure for conducting meetings of shareholders. Although our Declaration of Trust does not give our board of trustees any power to disapprove shareholder nominations for the election of trustees or proposals recommending certain action, they may have the effect of precluding a contest for the election of trustees or the consideration of shareholder proposals if proper procedures are not followed and of discouraging or deterring a third party from conducting a solicitation of proxies to elect its own slate of trustees or to approve its own proposal without regard to whether consideration of such nominees or proposals might be harmful or beneficial to us and our shareholders. Our Investment Adviser may not, without the approval of a vote by the holders of more than 50% of the outstanding shares entitled to vote on such matters: ● modify the Investment Advisory Agreement except for amendments that would not adversely affect the rights of our shareholders; ● except as otherwise permitted under the Investment Advisory Agreement, voluntarily withdraw as our investment adviser unless such withdrawal would not affect our tax status and would not materially adversely affect our shareholders; ● appoint a new investment adviser (other than a sub-adviser pursuant to the terms of the Investment Advisory Agreement and applicable law); ● sell all or substantially all of our assets other than in the ordinary course of our business or as otherwise permitted by law; or ● cause the merger or similar reorganization of the Fund. Amendment of the Declaration of Trust and Bylaws Our Declaration of Trust provides that shareholders are entitled to vote upon a proposed amendment to the Declaration of Trust if the amendment would adversely affect the rights of shareholders. Approval of any such amendment must be approved by the holders of more than 50% of the outstanding shares of the Fund entitled to vote on the matter. In addition, the affirmative vote of shareholders entitled to cast at least two-thirds of the votes entitled to

Risks Related to Our Business and Structure
General Description of Registrant [Abstract]
Risk [Text Block]	Risks Related to Our Business and Structure We are a relatively new company and have limited prior operating history. The Fund is a non-diversified, closed-end management investment company that has elected to be regulated as a BDC with limited prior operating history. As a result, prospective investors have no track record or history on which to base their investment decision. We are subject to all of the business risks and uncertainties associated with any new business, including the risk that we will not achieve our investment objective, that we will not qualify or maintain our qualification to be treated as a RIC, and that the value of your investment could decline substantially or become worthless. Further, GC Advisors has not previously offered a non-traded business development company. While we believe that the past professional experiences of GC Advisors’ investment team, including investment and financial experience of the GC Advisors’ senior management, will increase the likelihood that the GC Advisors will be able to manage the Fund successfully, there can be no assurance that this will be the case. We are subject to risks associated with the current interest rate environment and to the extent we use debt to finance our investments, changes in interest rates will affect our cost of capital and net investment income. To the extent we borrow money or issue debt securities or preferred stock to make investments, our net investment income will depend, in part, upon the difference between the rate at which we borrow funds or pay interest or dividends on such debt securities or preferred stock and the rate at which we invest these funds. In addition, many of our debt investments and borrowings have floating interest rates that reset on a periodic basis, and many of our investments are subject to interest rate floors. As a result, a change in market interest rates could have a material adverse effect on our net investment income. In periods of rising interest rates, our cost of funds will increase because the interest rates on the amounts borrowed under our credit facilities or certain other financing arrangements are typically floating, which could reduce our net investment income to the extent any debt investments have fixed interest rates, and the interest rate on investments with an interest rate floor above current levels will not increase until interest rates exceed the applicable floor. We can use interest rate risk management techniques in an effort to limit our exposure to interest rate fluctuations. Such techniques could include various interest rate hedging activities to the extent permitted by the 1940 Act and applicable commodities laws. These activities could limit our ability to participate in the benefits of lower interest rates with respect to the hedged borrowings. Adverse developments resulting from changes in interest rates or hedging transactions could have a material adverse effect on our business, financial condition and results of operations. You should also be aware that a rise in the general level of interest rates typically will lead to higher interest rates applicable to our debt investments, which could result in an increase of the amount of incentive fees payable to GC Advisors. In addition, a decline in the prices of the debt we own could adversely affect our NAV. Also, an increase in interest rates available to investors could make an investment in our Common Shares less attractive if we are not able to increase our distribution rate, which could reduce the value of our Common Shares. We operate in a highly competitive market for investment opportunities, which could reduce returns and result in losses. A number of entities compete with us to make the types of investments that we plan to make, and we believe that recent market trends, including sustained periods of low interest rates, have increased the number of competitors seeking to invest in loans to private, middle market and upper middle market companies in the United States. We compete with public and private funds, commercial and investment banks, commercial financing companies and, to the extent they provide an alternative form of financing, private equity and hedge funds. Many of our competitors are substantially larger and have considerably greater financial, technical and marketing resources than we do. For example, we believe some of our competitors could have access to funding sources that are not available to us. In addition, some of our competitors could have higher risk tolerances or different risk assessments, which could allow them to consider a wider variety of investments and establish more relationships than us. Furthermore, many of our competitors are not subject to the regulatory restrictions that the 1940 Act imposes on us as a business development company or the source of income, asset diversification and distribution requirements we must satisfy to qualify for and maintain our treatment as a RIC. The competitive pressures we face could have a material adverse effect on our business, financial condition, results of operations and cash flows. As a result of this competition, we can provide no assurance that we will be able to take advantage of attractive investment opportunities that arise from time to time, and we can provide no assurance that we will be able to identify and make investments that are consistent with our investment objective. An excess of the amount of capital in the private debt markets and overall competition for loans could result in short term returns for us that are lower than our long-term targets. In the event these conditions continue for an extended amount of time, they could have a material adverse effect on our business, financial condition and results of operations. Identifying, structuring and consummating investments involves competition among capital providers and market and transaction uncertainty. GC Advisors can provide no assurance that it will be able to identify a sufficient number of suitable investment opportunities or to avoid prepayment of existing investments to satisfy our investment objectives, including as necessary to effectively structure credit facilities or other forms of leverage. The loan origination market is very competitive, which can result in loan terms that are more favorable to borrowers, and conversely less favorable to lenders, such as lower interest rates and fees, weaker borrower financial and other covenants, borrower rights to cure defaults, and other terms more favorable to borrowers than current or historical norms. Increased competition could cause us to make more loans that are “cov-lite” in nature and, in a distressed scenario, there can be no assurance that these loans will retain the same value as loans with a full package of covenants. As a result of these conditions, the market for leveraged loans could become less advantageous than expected for us, and this could increase default rates, decrease recovery rates or otherwise harm our returns. The risk of prepayment is also higher in the current competitive environment if borrowers are offered more favorable terms by other lenders. The financial markets have experienced substantial fluctuations in prices and liquidity for leveraged loans. Any further disruption in the credit and other financial markets could have substantial negative effects on general economic conditions, the availability of required capital for companies and the operating performance of such companies. These conditions also could result in increased default rates and credit downgrades, and affect the liquidity and pricing of the investments made by us. Conversely, periods of economic stability and increased competition among capital providers could increase the difficulty of locating investments that are desirable for us. With respect to the investments we make, we do not seek to compete based primarily on the interest rates we offer, and we believe that some of our competitors could make loans with interest rates that will be lower than the rates we offer. In the secondary market for acquiring existing loans, we compete generally on the basis of pricing terms. With respect to all investments, we could lose some investment opportunities if we do not match our competitors’ pricing, terms and structure. However, if we match our competitors’ pricing, terms and structure, we could experience decreased net interest income, lower yields and increased risk of credit loss. We will also compete for investment opportunities with accounts managed or sponsored by GC Advisors or its affiliates. Although GC Advisors allocates opportunities in accordance with its allocation policy, allocations to such other accounts will reduce the amount and frequency of opportunities available to us and thus not necessarily be in the best interests of us and our security holders. Moreover, the performance of investments will not be known at the time of allocation. Covenant-lite loans may expose us to different risks, including with respect to liquidity, ability to restructure loans, credit risks and less protective loan documentation, than is the case with loans that contain financial maintenance covenants. Certain loans in our portfolio may consist of “covenant-lite” loans. Such loans may not require the borrower to maintain debt service or other financial ratios and do not include terms which allow the lender to monitor the performance of the borrower and declare a default if certain criteria are breached. Ownership of covenant-lite loans may expose us to different risks, including with respect to liquidity, ability to restructure loans, credit risks and less protective loan documentation, than is the case with loans that contain financial maintenance covenants. Rising interest rates could affect the value of our investments and make it more difficult for portfolio companies to make periodic payments on their loans. Interest rate risk refers to the risk of market changes in interest rates. Interest rate changes affect the value of debt. In general, rising interest rates will negatively impact the price of fixed rate debt, and falling interest rates will have a positive effect on price. Adjustable rate debt also reacts to interest rate changes in a similar manner, although generally to a lesser degree. Interest rate sensitivity is generally larger and less predictable in debt with uncertain payment or prepayment schedules. Further, rising interest rates make it more difficult for borrowers to repay debt, which could increase the risk of payment defaults. Any failure of one or more portfolio companies to repay or refinance its debt at or prior to maturity or the inability of one or more portfolio companies to make ongoing payments following an increase in contractual interest rates could have a material adverse effect on our business, financial condition, results of operations and cash flows. We are subject to risks associated with the transition away from LIBOR. Following their publication on June 30, 2023, no settings of the London Interbank Offered Rate (“LIBOR”) continue to be published on a representative basis and publication of many non-U.S. dollar LIBOR settings has been entirely discontinued. On July 29, 2021, the U.S. Federal Reserve System, in conjunction with the Alternative Reference Rates Committee, a steering committee comprised of large U.S. financial institutions, formally recommended replacing U.S.-dollar LIBOR with the Secured Overnight Financing Rate (“SOFR”), a new index calculated by short-term repurchase agreements, backed by Treasury securities. In April 2018, the Bank of England began publishing its proposed alternative rate, the Sterling Overnight Index Average (“SONIA”). Each of SOFR and SONIA significantly differ from LIBOR, both in the actual rate and how it is calculated. Further, on March 15, 2022, the Consolidation Appropriations Act of 2022, which includes the Adjustable Interest Rate (LIBOR) Act (“LIBOR Act”), was signed into law in the United States. This legislation establishes a uniform benchmark replacement process for certain financial contracts that mature after June 30, 2023 that do not contain clearly defined or practicable LIBOR fallback provisions. The legislation also creates a safe harbor that shields lenders from litigation if they choose to utilize a replacement rate recommended by the Board of Governors of the Federal Reserve. In addition, the U.K. Financial Conduct Authority (“FCA”), which regulates the publisher of LIBOR (ICE Benchmark Administration) has announced that it will require the continued publication of the one-, three- and six-month tenors of U.S.-dollar LIBOR on a non-representative synthetic basis until the end of September 2024, which may result in certain non-U.S. law-governed contracts and U.S. law-governed contracts not covered by the federal legislation remaining on synthetic U.S.-dollar LIBOR until the end of this period. Although the transition process away from LIBOR has become increasingly well-defined (e.g. the LIBOR Act now provides a uniform benchmark replacement for certain LIBOR-based instruments in the United States), the transition process is complex and it could cause a disruption in the credit markets generally and could have adverse impacts on our business financial condition and results of operations, including, among other things, increased volatility or illiquidity in markets for instruments that continue to rely on LIBOR or which have been transitioned away from LIBOR to a different rate like SOFR and, in any case, could result in a reduction in the value of certain investments held by the Fund. We are dependent upon GC Advisors for our success and upon its access to the investment professionals and partners of Golub Capital and its affiliates. We do not have any internal management capacity or employees. We rely on GC Advisors to manage and conduct our affairs and make all investment decisions. Subject to the oversight of our board of trustees, GC Advisors has sole discretion in originating, structuring, negotiating, purchasing, financing and eventually divesting our investments, and our investors will not be able to evaluate for themselves the merits of particular investments prior to us making such investments. We depend on the diligence, skill and network of business contacts of the senior investment professionals of GC Advisors to achieve our investment objective. GC Advisors’ investment committee, which consists of two members of our board of trustees and additional employees of Golub Capital LLC, provides oversight over our investment activities. We also cannot assure you that we will replicate the historical results achieved by members of the investment committee, and we caution you that our investment returns could be substantially lower than the returns achieved by them in prior periods. We expect that GC Advisors will evaluate, negotiate, structure, close and monitor our investments in accordance with the terms of the Investment Advisory Agreement. We can offer no assurance, however, that the senior investment professionals of GC Advisors will continue to provide investment advice to us. If these individuals do not maintain their existing relationships with Golub Capital LLC and its affiliates and do not develop new relationships with other sources of investment opportunities, we can provide no assurance that GC Advisors or its affiliates will be able to identify appropriate replacements or grow our investment portfolio. The loss of any member of GC Advisors’ investment committee or of other senior investment professionals of GC Advisors and its affiliates would limit our ability to achieve our investment objective and operate as we anticipate. This could have a material adverse effect on our financial condition, results of operations and cash flows. The Staffing Agreement provides that Golub Capital LLC makes available to GC Advisors experienced investment professionals and provides access to the senior investment personnel of Golub Capital LLC for purposes of evaluating, negotiating, structuring, closing and monitoring our investments. We are not a party to the Staffing Agreement and cannot assure you that Golub Capital LLC will fulfill its obligations under the agreement. If Golub Capital LLC fails to perform, we cannot assure you that GC Advisors will enforce the Staffing Agreement, that such agreement will not be terminated by either party or that we will continue to have access to the investment professionals of Golub Capital LLC and its affiliates or their information and deal flow. Our business model depends to a significant extent upon strong referral relationships with sponsors and investing in companies backed by private equity sponsors. Any inability of GC Advisors to maintain or develop these relationships, or the failure of these relationships to generate investment opportunities, could adversely affect our business. GC Advisors is highly dependent on relationships with private equity sponsors in connection with the sourcing of investments. If private equity sponsors find new sources of debt capital that are more advantageous to them, or if GC Advisors suffers reputational harm such that it becomes a less attractive source of capital for private equity sponsors, GC Advisors could have difficulty finding and sourcing new middle market debt investments. Private equity sponsors could experience financial distress, which could be related or unrelated to the portfolio companies to which we have exposure. Once in financial distress, such sponsors likely would be unable to provide the same level of managerial, operating or financial support to such portfolio companies, resulting in an increased risk of default or inability to repay remaining principal at maturity. From time to time, we expect to have direct or indirect exposure to companies controlled by private equity sponsors in which the sponsors have completed one or more dividend recapitalizations, thereby allowing the private equity sponsor to substantially reduce or eliminate its net investment in an underlying portfolio company. These investments generally present different investment characteristics to us than investments where a private equity sponsor retains a significant net contributed capital position in the company. These investments could experience a higher rate of default. Even when a default does not occur, private equity sponsors could be less willing to provide ongoing financial, managerial or operating support to a portfolio company after it has received one or more capital distributions on its investment. We believe that purchase price multiples of companies (as measured by the price paid by a private equity sponsor to purchase a company divided by the company’s trailing twelve-month earnings) to which we have direct or indirect exposure are close to all-time highs. When considering the appropriate amount of financing to provide a prospective borrower, GC Advisors considers the value cushion as measured by the difference between the enterprise value of the company and the total amount of financing. If market purchase price multiples decline or if a portfolio company experiences financial distress, the value cushion supporting our investment could deteriorate and the investment could become impaired, resulting in losses for us. The risk of such losses for us are greater during periods when purchase price multiples are close to all-time highs. We can provide no assurance that we will be able to replicate the historical results achieved by other entities managed or sponsored by members of GC Advisors’ investment committee, or by GC Advisors or its affiliates. Investors are cautioned that past investment performance of similar portfolios and other investment vehicles managed by GC Advisors or its affiliates is not indicative of how we will perform. Our investments could differ from some existing accounts and funds that are or have been sponsored or managed by members of GC Advisors’ investment committee, GC Advisors or affiliates of GC Advisors. Investors in our securities are not acquiring an interest in any accounts that are or have been sponsored or managed by members of GC Advisors’ investment committee, GC Advisors or affiliates of GC Advisors. We will often co-invest in portfolio investments with other accounts sponsored or managed by members of GC Advisors’ investment committee, GC Advisors or its affiliates. Such investments are subject to regulatory limitations and approvals by trustees who are not “interested persons,” as defined in the 1940 Act. We can offer no assurance, however, that we will obtain such approvals or develop opportunities that comply with such limitations. We also cannot assure you that we will replicate the historical results achieved by us or by members of the investment committee, and we caution you that our investment returns could be substantially lower than the returns achieved in prior periods. Additionally, all or a portion of the prior results were achieved in particular market conditions that might never be repeated. Moreover, current or future market volatility and regulatory uncertainty can have an adverse impact on our future performance. Our financial condition, results of operations and cash flows depend on our ability to manage our business effectively. Our ability to achieve our investment objective depends on our ability to manage our business and to grow. This depends, in turn, on GC Advisors’ ability to identify, invest in and monitor companies that meet our investment criteria. The achievement of our investment objectives on a cost-effective basis depends upon GC Advisors’ execution of our investment process, its ability to provide competent, attentive and efficient services to us and, to a lesser extent, our access to financing on acceptable terms. GC Advisors has substantial responsibilities under the Investment Advisory Agreement, as well as responsibilities in connection with the management of other accounts sponsored or managed by GC Advisors, members of GC Advisors’ investment committee or the Administrator. The personnel of the Administrator and its affiliates could be called upon to provide managerial assistance to our portfolio companies. These activities could distract them or slow our rate of investment. Any failure to manage our business and our future growth effectively could have a material adverse effect on our business, financial condition, results of operations and cash flows. There are significant potential conflicts of interest as a result of our arrangements with GC Advisors and its affiliates and GC Advisors’ investment committee that could affect our investment returns. As a result of our arrangements with GC Advisors and its affiliates and GC Advisors’ investment committee, there will be times when GC Advisors or such persons have interests that differ from those of our security holders, giving rise to a conflict of interest, many of which are described in the following risk factors. GC Advisors attempts to identify, monitor and mitigate conflicts of interest. Further, GC Advisors has implemented policies and procedures reasonably designed to ensure its clients are treated fairly and equitably over time. GC Advisors believes that these factors, together with Golub Capital’s commitment to put investors first, effectively mitigate the risks associated with such conflicts of interest. However, it can be difficult to ensure that conflicts of interest do not adversely affect us. There are conflicts related to the obligations of GC Advisors’ investment committee, GC Advisors or its affiliates have to other clients and conflicts related to fees and expenses of such other clients. The members of GC Advisors’ investment committee serve as officers, trustees or principals of entities that operate in the same or a related line of business as we do or of accounts sponsored or managed by GC Advisors or its affiliates. Currently, our trustees and certain of our officers also serve as trustees and officers of GBDC, GBDC 3, GDLC, GBDC 4 and GDLCU, each a closed-end, non-diversified management investment company that has also elected to be regulated as a business development company under the 1940 Act. Similarly, GC Advisors and its affiliates manage other clients with similar or competing investment objectives. GC Advisors’ management team will share its time and attention between us and other investment vehicles and accounts. Neither we nor any investor in us unaffiliated with GC Advisors will have any rights in or to independent ventures of GC Advisors or its affiliates or in the income or profits derived therefrom. GC Advisors does not expect to have any dedicated personnel who spend all or substantially all of their time managing our investing activities. In serving in these multiple capacities, GC Advisors and its personnel have obligations to other clients or investors in those entities, the fulfillment of which could conflict with the best interests of us or our shareholders. Economic disruption and uncertainty precipitated by certain events, including, for example, public health crises such as the COVID-19 pandemic, could require GC Advisors and its affiliates to devote additional time and focus to existing portfolio companies in which other funds and accounts managed by GC Advisors and its affiliates hold investments. The allocation of time and focus by personnel of GC Advisors and its affiliates to existing portfolio company investments held by other funds and accounts could reduce the time that such individuals have to spend on our investing activities. Our investment objective overlaps with the investment objectives of other affiliated accounts. For example, GC Advisors and its affiliates currently manage GBDC, GBDC 3, GDLC, GBDC 4, GDLCU and multiple private funds and separate accounts that pursue an investment strategy similar to or overlapping with ours, some of which will seek additional capital from time to time. We compete with these and other accounts sponsored or managed by GC Advisors and its affiliates for capital and investment opportunities. As a result, GC Advisors and its affiliates face conflicts in the allocation of investment opportunities among us and other accounts advised by or affiliated with GC Advisors and, in certain circumstances, in the timing of the sale of an investment. Certain of these accounts provide for higher management or incentive fees, allow GC Advisors to recover greater expense reimbursements or overhead allocations, and/or permit GC Advisors and its affiliates to receive higher origination and other transaction fees, all of which could contribute to this conflict of interest and create an incentive for GC Advisors to favor such other accounts. For example, the 1940 Act restricts GC Advisors from receiving more than a 1% fee in connection with loans that we acquire, or originate, a limitation that does not exist for certain other accounts. GC Advisors seeks to allocate investment opportunities among eligible accounts in a manner that is fair and equitable over time and consistent with its allocation policy. However, we can offer no assurance that such opportunities will be allocated to us fairly or equitably in the short-term or over time, and there can be no assurance that we will be able to participate in all investment opportunities that are suitable to us. Furthermore, because allocations under GC Advisors’ allocation policy are based on total capital of the relevant investing funds, including us, we expect to receive smaller allocations relative to larger accounts, including accounts that can incur material amounts of leverage, which could have a material adverse effect on our business, financial condition, results of operations and cash flows during such ramp-up period. With respect to the sale of investments, the sale of an investment by one account advised by GC Advisors or its affiliates could potentially adversely affect the market value of the interests in such investment that continue to be held by other accounts, including us. GC Advisors’ investment committee, GC Advisors or its affiliates could, from time to time, possess material non-public information, limiting our investment discretion. Principals of GC Advisors and its affiliates and members of GC Advisors’ investment committee could serve as directors of, or in a similar capacity with, companies in which we invest, the securities of which are purchased or sold on our behalf. In the event that material non-public information is obtained with respect to such companies, or we become subject to trading restrictions under the internal trading policies of those companies or as a result of applicable law or regulations, we could be prohibited for a period of time from purchasing or selling the securities of such companies, and this prohibition could have an adverse effect on us. Our management and incentive fee structure creates incentives for GC Advisors that are not fully aligned with the interests of our shareholders and could induce GC Advisors to make certain investments, including speculative investments. In the course of our investing activities, we pay management and incentive fees to GC Advisors. We pay to GC Advisors an incentive fee that is based on the performance of our portfolio and an annual base management fee that is based on the value of our net assets as of the beginning of the first business day of the month. Because the incentive fee is based on the performance of our portfolio, GC Advisors may be incentivized to make investments on our behalf that are riskier or more speculative than would be the case in the absence of such compensation arrangement. The way in which the incentive fee is determined may also encourage GC Advisors to use leverage to increase the return on our investments. Our compensation arrangements could therefore result in our making riskier or more speculative investments than would otherwise be the case. This could result in higher investment losses, particularly during cyclical economic downturns. Additionally, the incentive fee payable by us to GC Advisors could create an incentive for GC Advisors to cause us to realize capital gains or losses that are not in the best interests of us or our shareholders. Under the incentive fee structure, GC Advisors benefits when we recognize capital gains and, because GC Advisors determines when an investment is sold, GC Advisors controls the timing of the recognition of such capital gains. Our board of trustees is charged with protecting our shareholders’ interests by monitoring how GC Advisors addresses these and other conflicts of interest associated with its management services and compensation. The part of the management and incentive fees payable to GC Advisors that relates to our net investment income is computed and paid on income that includes interest income that has been accrued but not yet received in cash, such as market discount, debt instruments with payment-in-kind (“PIK”) interest, preferred shares with PIK dividends, zero coupon securities, and other deferred interest instruments. This compensation arrangement creates an incentive for GC Advisors to make investments on our behalf that are riskier or more speculative, including debt financings that provide for deferred interest, rather than current cash payments of interest. Under these investments, we accrue the interest over the life of the investment but do not receive the cash income from the investment until the end of the term. Our net investment income used to calculate the income portion of our investment fee, however, includes accrued interest. GC Advisors has an incentive to invest in deferred interest securities in circumstances where it would not have done so but for the opportunity to continue to earn the fees even when the issuers of the deferred interest securities would not be able to make actual cash payments to us on such securities. This risk could be increased because GC Advisors is not obligated to reimburse us for any fees received even if we subsequently incur losses or never receive in cash the deferred income that was previously accrued. Our securities could be purchased by GC Advisors or its affiliates. Affiliates of GC Advisors have purchased, and GC Advisors and its affiliates in the future expect to purchase, certain of our securities. The purchase of our securities, including our Common Shares, by GC Advisors and its affiliates could create certain risks. For example, GC Advisors and its affiliates could have an interest in disposing of our sec
Risks Related to Our Investments
General Description of Registrant [Abstract]
Risk [Text Block]	Risks Relating to Our Investments Economic recessions or downturns could impair our portfolio companies and defaults by our portfolio companies will harm our operating results. Many of our portfolio companies are susceptible to economic slowdowns or recessions and could be unable to repay our loans during these periods. Therefore, our non-performing assets are likely to increase and the value of our portfolio is likely to decrease during these periods. Adverse economic conditions could decrease the value of collateral securing any of our loans and the value of any equity investments. A severe recession could further decrease the value of such collateral and result in losses of value in our portfolio and a decrease in our revenues, net income, assets and net worth. Economic slowdowns or recessions could lead to financial losses in our portfolio and a decrease in revenues, net income and assets. Unfavorable economic conditions also could increase our funding costs, limit our access to the capital markets or result in a decision by lenders not to extend credit to us. These events could prevent us from increasing our investments and harm our operating results. Any deterioration of general economic conditions could lead to significant declines in corporate earnings or loan performance, and the ability of corporate borrowers to service their debt, any of which could trigger a period of global economic slowdown, and have an adverse impact on our performance and financial results, and the value and the liquidity of our investments. In an economic downturn, we could have non-performing assets or an increase in non-performing assets, and we would anticipate that the value of our portfolio would decrease during these periods. Failure to satisfy financial or operating covenants imposed by lenders to a portfolio company, including us, could lead to defaults and, potentially, acceleration of payments on such loans and foreclosure on the assets representing collateral for the portfolio company’s obligations. Cross default provisions under other agreements could be triggered and thus limit the portfolio company’s ability to satisfy its obligations under any debt that we hold and affect the value of any equity securities we own. We would expect to incur expenses to the extent necessary to seek recovery upon default or to negotiate new terms with a portfolio company following or in anticipation of a default. Inflation could adversely affect the business, results of operations and financial condition of our portfolio companies. Certain of our portfolio companies are in industries that could be impacted by inflation. If such portfolio companies are unable to pass any increases in their costs of operations along to their customers, it could adversely affect their operating results and impact their ability to pay interest and principal on our loans, particularly if interest rates rise in response to inflation. In addition, any projected future decreases in our portfolio companies’ operating results due to inflation could adversely impact the fair value of those investments. Any decreases in the fair value of our investments could result in future realized or unrealized losses and therefore reduce our net assets resulting from operations. Our debt investments are risky and we could lose all or part of our investments. The debt that we invest in is typically not initially rated by any rating agency, but we believe that if such investments were rated, they would be below investment grade (rated lower than “Baa3” by Moody’s Investors Service, lower than “BBB-” by Fitch Ratings or lower than “BBB-” by Standard & Poor’s Ratings Services), which under the guidelines established by these entities is an indication of having predominantly speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal. Bonds that are rated below investment grade are sometimes referred to as “high yield bonds” or “junk bonds.” Therefore, our investments could result in an above average amount of risk and volatility or loss of principal. Our investments in leveraged portfolio companies are risky, and we could lose all or part of our investment. Investment in leveraged companies involves a number of significant risks. Leveraged companies in which we invest could have limited financial resources and could be unable to meet their obligations under their debt securities that we hold. These companies could be subject to restrictive financial and operating covenants and their leverage could impair their ability to finance their future operations and capital needs. As a result, these companies’ flexibility to respond to changing business and economic conditions and to take advantage of business opportunities could be limited. Such developments could be accompanied by a deterioration in the value of any collateral and a reduction in the likelihood of our realizing any guarantees that we could have obtained in connection with our investment. Smaller leveraged companies also could have less predictable operating results and could require substantial additional capital to support their operations, finance their expansion or maintain their competitive position. Our investments in private and middle market portfolio companies are risky, and we could lose all or part of our investment. Investment in private and middle market companies involves a number of significant risks. Generally, little public information exists about these companies, and we rely on the ability of GC Advisors’ investment professionals to obtain adequate information to evaluate the potential returns from investing in these companies. If GC Advisors is unable to uncover all material information about these companies, it would not be able to make a fully informed investment decision, and we could lose money on our investments. Compared to larger companies, middle market companies typically have shorter operating histories, more limited financial resources, newer technologies and/or products, smaller market shares, less experienced management teams and less predictable operating results, and often participate in quickly evolving markets, and are more reliant on a small number of products, managers or clients. Middle market companies could also require substantial additional capital to support their operations, finance expansion or maintain their competitive position and could have difficulty accessing the capital markets to meet future capital needs, which could limit their ability to grow or to repay their outstanding indebtedness upon maturity. In addition, the middle market companies in which we invest could be subject to governmental and non-governmental regulations, including by federal and state regulators and various self-regulatory organizations and the costs of complying with these laws and regulations could be more material to the company as compared to a larger company. If a company in which we directly or indirectly invest fails to comply with an applicable regulatory regime, it could be subject to fines, injunctions, operating restrictions or criminal prosecution, any of which could materially and adversely affect the value of our investment. We will not control a portfolio company’s management or the manner in which a company’s management addresses the company’s risks except in the event that a portfolio company defaults on its loan from us and we seek to enforce our security interest. In addition, middle market companies often require additional financing to expand or maintain their competitive position, and they could have a more difficult time obtaining additional capital than larger companies. An important concern in making investments is the possibility of material misrepresentation or omission on the part of the portfolio company. Such inaccuracy or incompleteness can adversely affect, among other things, the valuation of collateral, other debt obligations, our ability to perfect or effectuate a lien on the collateral securing a loan or other debt obligation, the financial condition of the issuer, or the business prospects of the issuer. We will rely upon the accuracy and completeness of representations made by portfolio companies to the extent reasonable. However, there can be no guarantee that such representations are accurate or complete. If the issuer of securities purchased by us does not perform to GC Advisors’ expectations, the value of its equity and debt securities would likely decline and the issuer could default on its obligations. Poor performance can be caused by a number of factors, including failures of management, competitive pressures, pressure by customers and suppliers, labor unrest, or force majeure events, such as the COVID-19 pandemic. While GC Advisors intends to invest in portfolio companies in industries that it believes are resistant to recessions, there can be no assurance that such portfolio companies will not be adversely affected by other market or economic conditions. The value of our investments in loans will likely be detrimentally affected to the extent a borrower defaults on its obligations, there is insufficient collateral, and/or there are extensive legal and other costs incurred in collecting on a defaulted loan. GC Advisors will attempt to minimize this risk, for example, by maintaining low loan-to-liquidation values with each loan and the collateral underlying the loan. However, there can be no assurance that the liquidation value assigned by GC Advisors would be realized by the portfolio company upon liquidation, nor can there be any assurance that such collateral will retain its value. In addition, certain of our loans will be supported, in whole or in part, by personal guarantees made by the borrower or an affiliate of the borrower. If such guarantee is called and the guarantor fails to meet its obligations under the guarantee, the amount realizable with respect to a loan will generally be detrimentally affected. There could be a monetary as well as a time cost involved in collecting on defaulted loans and, if applicable, taking possession of various types of collateral. In addition, any activity deemed to be active lending/origination by us could subject it to additional regulation. An investment strategy focused primarily on privately held companies presents certain challenges, including, but not limited to, the lack of available information about these companies. We invest primarily in privately held companies. Because private companies have reduced access to the capital markets, such companies could have diminished capital resources and ability to withstand financial distress. Often, the depth and breadth of experience of management in private companies tends to be less than that at public companies, which makes such companies more likely to depend on the management talents and efforts of a smaller group of persons and/or persons with less depth and breadth of experience. Therefore, the decisions made by such management teams and/or the departure of one or more of these persons could have a material adverse impact on the portfolio company and, as a result our investments. We would be subject to risks if we are required to assume operation of portfolio companies upon default. We, together with other funds managed by GC Advisors and its affiliates, would be expected to take over a portfolio company if the company defaults on its loans. Depending on factors including the health of the economy, the credit cycle, and the portfolio companies’ various industries, it is reasonable to assume that portfolio companies will default over time, and this risk is significantly increased in periods of market uncertainty, including as a result of global health crises, such as the COVID-19 pandemic, or periods of elevated inflation and rising interest rates. In such circumstances, we and the other funds would likely seek to enforce our rights under the applicable credit documentation and could opt to take over such portfolio companies. When a portfolio company is taken over, we and the other funds and their investors are subject to different risks than we are as holders of interests in loans to such portfolio company. Operating a portfolio company, even for a limited period of time pending the sale of collateral, can distract senior personnel of GC Advisors and its affiliates from their normal business. Additionally, defaulting portfolio companies often require additional capital to be effectively turned around. There is no guarantee that any defaulting portfolio company can be turned around or that our investments in such portfolio company will be successful. Finally, operating a portfolio company could subject us to potential liabilities, including management, employment, and/or environmental liabilities. The lack of liquidity in our investments could adversely affect our business. The debt to which we are primarily exposed is expected to consist predominantly of loans and notes that are obligations of corporations, partnerships or other entities. This debt often has no, or only a limited, trading market. The investment in illiquid debt will often restrict our ability to dispose of investments in a timely fashion, for a fair price, or at all. If an underlying issuer of debt experiences an adverse event, this illiquidity would make it more difficult for us to sell such debt, and we could instead be required to pursue a workout or alternate way out of the position. To the extent debt in a portfolio company is also held by other third-party investors, we would generally have limited control over a workout or alternate means of disposition and the person(s) having such control could have interests that are not aligned with ours. We would likely also face other restrictions on our ability to liquidate an investment in a portfolio company to the extent that we, GC Advisors, Golub Capital or any of its affiliates have material non-public information regarding such portfolio company. Price declines and illiquidity in the corporate debt markets could adversely affect the fair value of our portfolio investments, reducing our NAV through increased net unrealized depreciation. As a business development company, we are required to carry our investments at market value or, if no market value is ascertainable, at fair value as determined in good faith by our board of trustees. The fair value methodology utilized is in accordance with the fair value principles established by the Accounting Standards Codification Topic 820. Our board of trustees uses the services of one or more independent service providers to review the valuation of our illiquid investments. Valuations reflect significant events that affect the value of the instruments. As part of the valuation process, we could take into account the following types of factors, if relevant, in determining the fair value of our investments: ● a comparison of the portfolio company’s securities to publicly traded securities; ● the enterprise value of the portfolio company; ● the nature and realizable value of any collateral; ● the portfolio company’s ability to make payments and its earnings and discounted cash flow; ● the markets in which the portfolio company does business; and ● changes in the interest rate environment and the credit markets generally that could affect the price at which similar investments could be made in the future and other relevant factors. The fair value measurement seeks to approximate the price that would be received for an investment on a current sale and assumes that the transaction to sell an asset occurs in the principal market for such asset or, in the absence of a principal market, the most advantageous market for such asset, which could be a hypothetical market, and excludes transaction costs. When an external event such as a purchase transaction, public offering or subsequent equity sale occurs, we use the pricing indicated by the external event to corroborate our valuation. We record decreases in the market values or fair values of our investments as unrealized depreciation. Declines in prices and liquidity in the corporate debt markets could result in significant net unrealized depreciation in our portfolio. The effect of all of these factors on our portfolio could reduce our NAV by increasing net unrealized depreciation in our portfolio. Depending on market conditions, we could incur substantial realized losses and could suffer additional unrealized losses in future periods, which could have a material adverse effect on our business, financial condition, results of operations and cash flows. Because orderly markets currently do not exist for some investments, and because valuations, and particularly valuations of private investments and private companies, require judgment, are inherently uncertain, could fluctuate over short periods and are often based on estimates, our determinations of the fair value of investments could differ materially from the values that would have been used had a ready market existed for such investments. Our portfolio companies could prepay loans, which could reduce our yields if capital returned cannot be invested in transactions with equal or greater expected yields. The loans in our investment portfolio could be prepaid at any time, generally with little advance notice. Whether a loan is prepaid will depend both on the continued positive performance of the portfolio company and the existence of favorable financing market conditions that allow such company the ability to replace existing financing with less expensive capital. As market conditions change, we do not know when, and if, prepayment could be possible for each portfolio company. Certain fixed-income securities are subject to the risk of unanticipated prepayment. Prepayment risk is the risk that, when interest rates fall, the issuer will redeem the security prior to the security’s expected maturity. It is possible that we will reinvest the proceeds from such a redemption at a lower interest rate, resulting in less income to us. Securities subject to prepayment risk generally offer less potential for gains when prevailing interest rates fall. If we buy those securities at a premium, accelerated prepayments on those securities could cause us to lose a portion of its principal investment. The impact of prepayments on the price of a security can be difficult to predict and could increase the security’s price volatility. We are subject to credit and default risk and our portfolio companies could be unable to repay or refinance outstanding principal on their loans at or prior to maturity. Credit risk refers to the likelihood that a borrower will default in the payment of principal and/or interest. Financial strength and solvency of a borrower are the primary factors influencing credit risk. Lack or inadequacy of collateral or credit enhancement for a debt instrument could also affect its credit risk. Credit risk can change over the life of a loan, and securities and other debt instruments that are rated by rating agencies can be downgraded. This risk and the risk of default is increased to the extent that the loan documents do not require the portfolio companies to pay down the outstanding principal of such debt prior to maturity, which is expected to be a common feature among many of our loan investments. Investments with a deferred interest feature, such as original issue discount income and PIK interest, could represent a higher credit risk than investments that must pay interest in full in cash on a regular basis. A significant downturn in the economy or a particular economic sector could have a significant impact on the business prospects of the portfolio companies to which we are exposed, whether directly or indirectly. Such developments could adversely affect the ability of such companies to comply with their loan repayment obligations. It is possible that the issuer of a note or other instrument in which we invest could default on its debts, in which case we could lose most or all of our investment in that instrument, subjecting us to significant loss. The risk and magnitude of losses associated with defaults could be increased where the instrument is leveraged. We could have difficulty sourcing investment opportunities. While we currently hold a portfolio of investments, we have not yet identified additional potential investments for our portfolio that we will acquire with the proceeds of any offering of securities or repayments of investments currently in our portfolio. Privately negotiated investments in loans and illiquid securities or private middle market companies require substantial due diligence and structuring, and we cannot provide any assurance that we will achieve our anticipated investment pace. As a result, investors will not be able to evaluate any future portfolio company investments prior to purchasing our securities. Additionally, GC Advisors selects all of our investments, and our shareholders will have no input with respect to such investment decisions. These factors increase the uncertainty, and thus the risk, of investing in our securities. We anticipate that we will use substantially all of the net proceeds of any sale of our securities within approximately 60 days of each subscription closing, depending on the availability of appropriate investment opportunities consistent with our investment objectives and market conditions. Until such appropriate investment opportunities can be found, we could also invest the net proceeds in cash, cash equivalents, U.S. government securities and high-quality debt investments that mature in one year or less from the date of investment. We expect these temporary investments to earn yields substantially lower than the income that we expect to receive in respect of our targeted investment types. As a result, any distributions we make during this period could be substantially smaller than the distributions that we expect to pay when our portfolio is fully invested. We are a non-diversified investment company within the meaning of the 1940 Act and, therefore we are not limited with respect to the proportion of our assets that could be invested in securities of a single issuer. We are classified as a non-diversified investment company within the meaning of the 1940 Act, which means that we are not limited by the 1940 Act with respect to the proportion of our assets that we could invest in securities of a single issuer. To the extent that we assume large positions in the securities of a small number of issuers, our NAV could fluctuate to a greater extent than that of a diversified investment company as a result of changes in the financial condition or the market’s assessment of the issuer. We could also be more susceptible to any single economic or regulatory occurrence than a diversified investment company. Beyond our asset diversification requirements as a RIC under the Code, we do not have fixed guidelines for diversification, and our investments could be concentrated in relatively few portfolio companies. Although we are classified as a non-diversified investment company within the meaning of the 1940 Act, we maintain the flexibility to operate as a diversified investment company and could do so for an extended period of time. Our portfolio could be concentrated in a limited number of portfolio companies and industries, which will subject us to a risk of significant loss if any of these companies defaults on its obligations under any of its debt instruments or if there is a downturn in a particular industry. It is possible that our portfolio could be concentrated in a limited number of portfolio companies and industries. As a result, our interests could be impaired by the concentration of our investments in any one obligor or obligors in a particular industry or geographic location in the event that such obligor, industry or geographic location were to experience adverse business conditions or other adverse events, including as a result of the effects of a global health pandemic such as the COVID-19 pandemic or during periods of elevated inflation and rising interest rates. In addition, defaults could be highly correlated with particular obligors, industries or geographic locations. If loans involving a particular obligor, industry or geographic location represent more than a small proportion of our portfolio, and that obligor, industry or geographic location were to experience difficulties that would affect payments on the loans, the overall timing and amount of collections on the loans held by us could differ from what was expected. We could hold the debt securities of leveraged companies that could, due to the significant volatility of such companies, enter into bankruptcy proceedings. Leveraged companies could experience bankruptcy or similar financial distress, and the risk of these events would be expected to significantly increase upon the occurrence of adverse events, including, for example, an inflationary economic environment or a global health crisis, such as the COVID-19 pandemic. The bankruptcy process has a number of significant inherent risks. Many events in a bankruptcy proceeding are products of contested matters and adversarial proceedings and are beyond the control of the creditors. A bankruptcy filing by an issuer could have adverse and permanent effects on the issuer. If the proceeding is converted to a liquidation, the value of the issuer will not necessarily equal the liquidation value that was believed to exist at the time of the investment. A bankruptcy or other workout, often raises conflicts of interest (including, for example, conflicts over proposed waivers and amendments to debt covenants), including between investors who hold different types of interests in the applicable company. The duration of a bankruptcy proceeding is also difficult to predict, and a creditor’s return on investment can be adversely affected by delays until the plan of reorganization or liquidation ultimately becomes effective. The administrative costs of a bankruptcy proceeding are frequently high and are paid out of the debtor’s estate prior to any return to creditors. Because the standards for classification of claims under bankruptcy law are vague, our influence with respect to the class of securities or other obligations it owns could be reduced by increases in the number and monetary value of claims in the same class or by different classification and treatment. In the early stages of the bankruptcy process, it is often difficult to estimate the extent of, or even to identify, any contingent claims that might be made. In addition, certain claims that have priority by law (for example, claims for taxes) can be substantial. Depending on the facts and circumstances of our investments and the extent of our involvement in the management of a portfolio company, upon the bankruptcy of a portfolio company, a bankruptcy court could recharacterize our debt investments as equity interests and subordinate all or a portion of our claim to that of other creditors. This could occur even though we have structured our investment as senior debt. Our failure to make follow-on investments in our portfolio companies could impair the value of our portfolio. Following an initial investment in a portfolio company, we could make additional investments in that portfolio company as “follow-on” investments, in seeking to: ● increase or maintain in whole or in part our position as a creditor or equity ownership percentage in a portfolio company; ● exercise warrants, options or convertible securities that were acquired in the original or subsequent financing; or ● preserve or enhance the value of our investment. We have discretion to make follow-on investments, subject to the availability of capital resources. Failure on our part to make follow-on investments could, in some circumstances, jeopardize the continued viability of a portfolio company and our initial investment, or could result in a missed opportunity for us to increase our participation in a successful portfolio company. Even if we have sufficient capital to make a desired follow-on investment, we could elect not to make a follow-on investment because we do not want to increase our level of risk, because we prefer other opportunities or because of regulatory or other considerations. Our ability to make follow-on investments could also be limited by GC Advisors’ allocation policy. If we are unable to raise substantial funds, then we will be more limited in the number and type of investments we may make, our expenses may be higher relative to our total assets, and the value of your investment in us may be reduced in the event our assets under-perform. Amounts that we raise may not be sufficient for us to purchase a broad portfolio of investments. To the extent that less than the maximum number of Common Shares is subscribed for, the opportunity for us to purchase a broad portfolio of investments may be decreased and the returns achieved on those investments may be reduced as a result of allocating all of our expenses among a smaller capital base. If we are unable to raise substantial funds, we may not achieve certain economies of scale and our expenses may represent a larger proportion of our total assets. Because we generally do not hold controlling equity interests in our portfolio companies, we generally will not be able to exercise control over our portfolio companies or to prevent decisions by management of our portfolio companies that could decrease the value of our investments. To the extent we do not hold controlling equity positions in our portfolio companies, we are subject to the risk that a portfolio company makes business decisions with which we disagree, and that the management and/or shareholders of a portfolio company could take risks or otherwise act in ways that are adverse to our interests. Due to the lack of liquidity of the debt and equity investments that we typically hold in our portfolio companies, we can provide no assurance that we will be able to dispose of our investments in the event we disagree with the actions of a portfolio company and could therefore suffer a decrease in the value of our investments. Our portfolio companies could incur debt that ranks equally with, or senior to, our investments in such companies and such portfolio companies could fail to generate sufficient cash flow to service their debt obligations to us. We have invested and intend to invest a portion of our capital in second lien and subordinated loans issued by our portfolio companies, and we could have exposure to a variety of debt that captures particular layers of a borrower’s credit structure, such as “last out” or “second lien” debt, or other subordinated investments that rank below other obligations of the borrower in right of payment. Subordinated investments are subject to greater risk of loss than senior obligations where there are adverse changes to the financial condition of the borrower or a decline in general economic conditions. Subordinated investments could expose us to particular risks in a distress scenario, such as the risk that creditors are not aligned. Holders of subordinated investments generally have less ability to affect the results of a distressed scenario than holders of more senior investments. Additionally, lenders to companies operating in workout modes are, in certain circumstances, subject to potential liabilities that could exceed the amount of such loan purchased by us. We have made in the past, and could make in the future, unsecured loans to portfolio companies, meaning that such loans will not benefit from any interest in collateral of such companies. Liens on a portfolio company’s collateral, if any, will secure the portfolio company’s obligations under its outstanding secured debt and could secure certain future debt that is permitted to be incurred by the portfolio company under its secured loan agreements. The holders of obligations secured by such liens will generally control the liquidation of, and be entitled to receive proceeds from, any realization of such collateral to repay their obligations in full before us. In addition, the value of such collateral in the event of liquidation will depend on market and economic conditions, the availability of buyers and other factors. There can be no assurance that the proceeds, if any, from sales of such collateral would be sufficient to satisfy our unsecured loan obligations after payment in full of all loans secured by collateral. If such proceeds were not sufficient to repay the outstanding secure
Risks Relating to Investors in Our Securities
General Description of Registrant [Abstract]
Risk [Text Block]	Risks Relating to Investors in Our Securities Investing in our securities could involve an above average degree of risk. The investments we make in accordance with our investment objective could result in a higher amount of risk than alternative investment options and a higher risk of volatility or loss of principal. Our investments in portfolio companies involve higher levels of risk, and therefore, an investment in our securities may not be suitable for someone with a lower risk tolerance. In addition, our Common Shares are intended for long-term investors and should not be treated as a trading vehicle. There is a risk that investors in our equity securities will not receive distributions or that our distributions will not grow over time and a portion of our distributions could be a return of capital. We intend to make distributions on a quarterly basis to our shareholders out of assets legally available for distribution. We cannot assure you that we will achieve investment results that will allow us to make a specified level of cash distributions or year-to-year increases in cash distributions. Our ability to pay distributions could be adversely affected by the impact of one or more of the risk factors described in this Registration Statement. Due to the asset coverage test applicable to us under the 1940 Act as a business development company, we could be limited in our ability to make distributions. In addition, all distributions are and will be paid at the discretion of our board of trustees and will depend on our earnings, financial condition, maintenance of our RIC status, compliance with applicable business development company regulations and such other factors as our board of trustees could deem relevant from time to time. If we declare a distribution and if more shareholders opt to receive cash distributions rather than participate in our distribution reinvestment plan, we could be forced to sell some of our investments in order to make cash distribution payments. In the event that we encounter delays in locating suitable investment opportunities, we could also pay all or a substantial portion of our distributions from the proceeds of private placements of our Common Shares or from borrowings in anticipation of future cash flow, which could constitute a return of shareholders’ capital. To the extent we make distributions to shareholders that include a return of capital, such portion of the distribution essentially constitutes a return of the shareholder’s investment. Although such return of capital is generally not currently taxable, such distributions would generally decrease a shareholder’s basis in our Common Shares and could therefore increase such shareholder’s tax liability for capital gains upon the future sale or other disposition of such shares. A return of capital distribution could cause a shareholder to recognize a capital gain from the sale of our Common Shares even if the shareholder sells its shares for less than the original purchase price. Distributions from the proceeds of private placements of our common shares or from borrowings could also reduce the amount of capital we ultimately invest in our portfolio companies. We have not established any limit on the amount of funds we can use from available sources, such as borrowings, if any, or proceeds from private placements of our Common Shares, to fund distributions (which could reduce the amount of capital we ultimately invest in assets). Any distributions made from sources other than cash flow from operations or relying on fee or expense reimbursement waivers, if any, from GC Advisors or the Administrator are not based on our investment performance, and can only be sustained if we achieve positive investment performance in future periods and/or GC Advisors or the Administrator continues to make such expense reimbursements, if any. The extent to which we pay distributions from sources other than cash flow from operations will depend on various factors, including the level of participation in our distribution reinvestment plan, how quickly we invest the proceeds from any offerings of our securities and the performance of our investments. There can be no assurance that we will achieve such performance in order to sustain any level of distributions, or be able to pay distributions at all. GC Advisors and the Administrator have no obligation to waive fees or receipt of expense reimbursements, if any. If we issue preferred shares, debt securities or convertible debt securities, the NAV of our Common Shares could become more volatile. We cannot assure you that the issuance of preferred shares and/or debt securities would result in a higher yield or return to the holders of our Common Shares. The issuance of preferred shares, debt securities or convertible debt would likely cause the NAV of our Common Shares to become more volatile. If the dividend rate on the preferred shares, or the interest rate on the debt securities, were to approach the net rate of return on our investment portfolio, the benefit of leverage to the holders of our Common Shares would be reduced. If the dividend rate on the preferred shares, or the interest rate on the debt securities, were to exceed the net rate of return on our portfolio, the use of leverage would result in a lower rate of return to the holders of our Common Shares than if we had not issued the preferred shares or debt securities. Any decline in the value of our portfolio would be borne entirely by the holders of our Common Shares. Therefore, if the value of our portfolio were to decline, the leverage would result in a greater decrease in NAV to the holders of our Common Shares than if we were not leveraged through the issuance of preferred shares. This decline in NAV would also tend to cause a greater decline in the net offering price for our Common Shares. There is also a risk that, in the event of a sharp decline in the value of our net assets, we would be in danger of failing to maintain required asset coverage ratios which may be required by the preferred shares, debt securities, convertible debt or units or of a downgrade in the ratings of the preferred shares, debt securities, convertible debt or units or our current investment income might not be sufficient to meet the dividend requirements on the preferred shares or the interest payments on the debt securities. In order to counteract such an event, we might need to liquidate investments in order to fund redemption of some or all of the preferred shares, debt securities or convertible debt. In addition, we would pay (and the holders of our Common Shares would bear) all costs and expenses relating to the issuance and ongoing maintenance of the preferred shares, debt securities, convertible debt or any combination of these securities. Holders of preferred shares, debt securities or convertible debt may have different interests than holders of Common Shares and may at times have disproportionate influence over our affairs. Holders of any preferred shares that we could issue will have the right to elect members of the board of trustees and have class voting rights on certain matters. The 1940 Act requires that holders of shares of preferred shares must be entitled as a class to elect two trustees at all times and to elect a majority of the trustees if dividends on such preferred shares are in arrears by two years or more, until such arrearage is eliminated. In addition, certain matters under the 1940 Act require the separate vote of the holders of any issued and outstanding preferred shares, including changes in fundamental investment restrictions and conversion to open-end status and, accordingly, preferred shareholders could veto any such changes. Restrictions imposed on the declarations and payment of dividends or other distributions to the holders of our Common Shares and preferred shares, both by the 1940 Act and by requirements imposed by rating agencies, might impair our ability to qualify for or maintain our treatment as a RIC for U.S. federal income tax purposes. Our common shareholders’ interest in us could be diluted if they do not fully exercise subscription rights in any rights offering. In addition, if the subscription price is less than our NAV per share, then common shareholders will experience an immediate dilution of the aggregate NAV of your shares. In the event we issue subscription rights, shareholders who do not fully exercise their subscription rights should expect that they will, at the completion of a rights offering, own a smaller proportional interest in us than would otherwise be the case if they fully exercised their rights. We cannot state precisely the amount of any such dilution in share ownership because we do not know at this time what proportion of the shares would be purchased as a result of such rights offering. In addition, if the subscription price is less than the NAV per share of our Common Shares, then our common shareholders would experience an immediate dilution of the aggregate NAV of their shares as a result of the offering. The amount of any decrease in NAV is not predictable because it is not known at this time what the subscription price and NAV per share will be on the expiration date of a rights offering or what proportion of the shares will be purchased as a result of such rights offering. Such dilution could be substantial. These dilutive effects could be exacerbated if we were to conduct multiple subscription rights offerings, particularly if such offerings were to occur over a short period of time. Our shareholders will experience dilution in their ownership percentage if they do not participate in our distribution reinvestment plan. All distributions declared in cash payable to shareholders that are participants in our distribution reinvestment plan are automatically reinvested in our Common Shares of the same class. As a result, our shareholders that do not participate in our distribution reinvestment plan will experience dilution in their ownership percentage of our Common Shares over time. Terms relating to redemption could materially adversely affect the return on any debt securities that we could issue. If we issue debt securities that are redeemable at our option, we could choose to redeem such debt securities at times when prevailing interest rates are lower than the interest rate paid on the debt securities. In addition, if our debt securities are subject to mandatory redemption, we could be required to redeem such debt securities also at times when prevailing interest rates are lower than the interest rate paid on the debt securities. In this circumstance, investors in our debt securities may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as the debt securities being redeemed.
General Risk Factors
General Description of Registrant [Abstract]
Risk [Text Block]	General Risk Factors We are currently in a period of capital markets disruption and economic uncertainty. The success of our activities is affected by general economic and market conditions, including, among others, interest rates, availability of credit, inflation rates, economic uncertainty, changes in laws, and trade barriers. These factors could affect the level and volatility of securities prices and the liquidity of our investments. Volatility or illiquidity could impair our profitability or result in losses. These factors also could adversely affect the availability or cost of our leverage, which would result in lower returns. In recent years, U.S. capital markets have experienced volatility and disruptions including as a result of the global COVID-19 pandemic, certain regional bank failures, and an inflationary economic environment. These disruptions in the capital markets have in the past and could in the future increase the spread between the yields realized on risk-free and higher risk securities, resulting in illiquidity in parts of the capital markets. Such disruptions could adversely affect our business, financial condition, results of operations and cash flows, and future market disruptions and/or illiquidity could negatively impact us. These unfavorable economic conditions could increase our funding costs and limit our access to the capital markets, and could result in a decision by lenders not to extend credit to us in the future. These events could limit our investments, our ability to grow and could negatively impact our operating results and the fair values of our debt and equity investments. Events outside of our control, including public health crises, could negatively affect our portfolio companies, our Investment Adviser and the results of our operations. Periods of market volatility could occur in response to pandemics or other events outside of our control. We, GC Advisors, and the portfolio companies in which we invest in could be affected by force majeure events (i.e., events beyond the control of the party claiming that the event has occurred, such as acts of God, fire, flood, earthquakes, outbreaks of an infectious disease, pandemic or any other serious public health concern, war, terrorism, labor strikes, government shutdowns, major plant breakdowns, pipeline or electricity line ruptures, failure of technology, defective design and construction, accidents, demographic changes, government macroeconomic policies, social instability, etc.). Some force majeure events could adversely affect the ability of a party (including us, GC Advisors, a portfolio company or a counterparty to us, GC Advisors, or a portfolio company) to perform its obligations until it is able to remedy the force majeure event. In addition, force majeure events, such as the cessation of the operation of equipment for repair or upgrade, could similarly lead to the unavailability of essential equipment and technologies. These risks could, among other effects, adversely impact the cash flows available from a portfolio company, cause personal injury or loss of life, including to a senior manager of GC Advisors or its affiliates, damage property, or instigate disruptions of service. In addition, the cost to a portfolio company or us of repairing or replacing damaged assets resulting from such force majeure event could be considerable. It will not be possible to insure against all such events, and insurance proceeds received, if any, could be inadequate to completely or even partially cover any loss of revenues or investments, any increases in operating and maintenance expenses, or any replacements or rehabilitation of property. Certain events causing catastrophic loss could be either uninsurable, or insurable at such high rates as to adversely impact us, GC Advisors, or portfolio companies, as applicable. Force majeure events that are incapable of or are too costly to cure could have permanent adverse effects. Certain force majeure events (such as war or an outbreak of an infectious disease) could have a broader negative impact on the world economy and international business activity generally, or in any of the countries in which we invest or our portfolio companies operate specifically. Such force majeure events could result in or coincide with: increased volatility in the global securities, derivatives and currency markets; a decrease in the reliability of market prices and difficulty in valuing assets; greater fluctuations in currency exchange rates; increased risk of default (by both government and private issuers); further social, economic, and political instability; nationalization of private enterprise; greater governmental involvement in the economy or in social factors that impact the economy; less governmental regulation and supervision of the securities markets and market participants and decreased monitoring of the markets by governments or self-regulatory organizations and reduced enforcement of regulations; limited, or limitations on, the activities of investors in such markets; controls or restrictions on foreign investment, capital controls and limitations on repatriation of invested capital; inability to purchase and sell investments or otherwise settle security or derivative transactions (i.e., a market freeze); unavailability of currency hedging techniques; substantial, and in some periods extremely high, rates of inflation, which can last many years and have substantial negative effects on credit and securities markets as well as the economy as a whole; recessions; and difficulties in obtaining and/or enforcing legal judgments. Additionally, a major governmental intervention into industry, including the nationalization of an industry or the assertion of control over one or more portfolio companies or its assets, could result in a loss to us, including if the investment in such portfolio companies is canceled, unwound or acquired (which could result in inadequate compensation). Any of the foregoing could therefore adversely affect the performance of us and our investments. We could experience fluctuations in our monthly operating results. We could experience fluctuations in our monthly operating results due to a number of factors, including the interest rate payable on any borrowings and the interest rate payable on the debt securities we acquire, the default rate on such securities, the number and size of investments we originate or acquire, the level of our expenses, variations in and the timing of the recognition of realized and unrealized gains or losses, the degree to which we encounter competition in our markets and general economic conditions. In light of these factors, results for any period should not be relied upon as being indicative of our performance in future periods. Political uncertainty could adversely affect our business U.S. and non-U.S. markets could experience political uncertainty and/or change that subjects investments to heightened risks, including, for instance, risks related to elections in the U.S., the large scale invasion of Ukraine by Russia that began in February 2022, or the effect on world leaders and governments of global health pandemics, such as the COVID-19 pandemic. These heightened risks could also include: increased risk of default (by both government and private issuers); greater social, trade, economic and political instability (including the risk of war or terrorist activity); greater governmental involvement in the economy; greater governmental supervision and regulation of the securities markets and market participants resulting in increased expenses related to compliance; greater fluctuations in currency exchange rates; controls or restrictions on foreign investment and/or trade, capital controls and limitations on repatriation of invested capital and on the ability to exchange currencies; inability to purchase and sell investments or otherwise settle security or derivative transactions (i.e., a market freeze); unavailability of currency hedging techniques; and slower clearance. During times of political uncertainty and/or change, global markets often become more volatile. There could also be a lower level of monitoring and regulation of markets while a country is experiencing political uncertainty and/or change, and the activities of investors in such markets and enforcement of existing regulations could become more limited. Markets experiencing political uncertainty and/or change could have substantial, and in some periods extremely high, rates of inflation for many years. Inflation and rapid fluctuations in inflation rates typically have negative effects on such countries’ economies and markets. Tax laws could change materially, and any changes in tax laws could have an unpredictable effect on us, our investments and our investors. There can be no assurance that political changes will not cause us or our investors to suffer losses. The continuing impact of Brexit on our investments is uncertain and could adversely affect our business. On January 31, 2020, the United Kingdom, or the UK, ended its membership in the European Union, or the EU, referred to as Brexit. Following the termination of a transition period, the UK and the EU entered into a trade and cooperation agreement to govern the future relationship between the parties, which was provisionally applied as of January 1, 2021 and entered into force on May 1, 2021 following ratification by the EU. With respect to financial services, the agreement leaves decisions on equivalence and adequacy to be determined by each of the UK and EU unilaterally in due course. As a result, certain UK licensed entities are unable to provide regulated services in a number of EU jurisdictions from the end of December 2020, absent regulatory relief or other measures implemented by individual countries. Such agreement is untested and could lead to ongoing political and economic uncertainty and periods of exacerbated volatility in both the United Kingdom and in wider European and global markets for some time. The longer term economic, legal, political and social implications of Brexit are unclear at this stage. Brexit has led to ongoing political and economic uncertainty and periods of increased volatility in both the UK and in wider European markets for some time. Brexit could lead to calls for similar referendums in other European jurisdictions, which could cause increased economic volatility in the European and global markets. This mid- to long-term uncertainty could have adverse effects on the economy generally and on our ability to earn attractive returns. In particular, currency volatility could mean that our returns are adversely affected by market movements and could make it more difficult, or more expensive, for us to execute prudent currency hedging policies. Potential decline in the value of the British Pound and/or the Euro against other currencies, along with the potential further downgrading of the UK’s sovereign credit rating, could also have an impact on the performance of certain investments made in the UK or Europe. New or modified laws or regulations governing our operations could adversely affect our business. We and our portfolio companies are subject to regulation by laws at the U.S. federal, state and local levels. These laws and regulations, as well as their interpretation, could change from time to time, including as the result of interpretive guidance or other directives from the U.S. President and others in the executive branch, and new laws, regulations and interpretations could also come into effect. For example, the current U.S. presidential administration could support an enhanced regulatory agenda that imposes greater costs on all sectors and on financial services companies in particular. Any such new or changed laws or regulations could have a material adverse effect on our business, and political uncertainty could increase regulatory uncertainty in the near term. The effects of legislative and regulatory proposals directed at the financial services industry or affecting taxation, could negatively impact the operations, cash flows or financial condition of us or our portfolio companies, impose additional costs on us or our portfolio companies, intensify the regulatory supervision of us or our portfolio companies or otherwise adversely affect our business or the business of our portfolio companies. In addition, if we do not comply with applicable laws and regulations, we could lose any licenses that we then hold for the conduct of our business and could be subject to civil fines and criminal penalties. We invest in securities of issuers that are subject to governmental and non-governmental regulations, including by federal and state regulators and various self-regulatory organizations. Companies participating in regulated activities could incur significant costs to comply with these laws and regulations. If a company in which we invest fails to comply with an applicable regulatory regime, it could be subject to fines, injunctions, operating restrictions or criminal prosecution, any of which could materially and adversely affect the value of our investment. Additionally, changes to the laws and regulations governing our operations, including those associated with RICs, could cause us to alter our investment strategy in order to avail ourselves of new or different opportunities or result in the imposition of corporate-level taxes on us. Such changes could result in material differences to our strategies and plans and could shift our investment focus from the areas of expertise of GC Advisors to other types of investments in which GC Advisors could have little or no expertise or experience. Any such changes, if they occur, could have a material adverse effect on our results of operations and the value of your investment. If we invest in commodity interests in the future, GC Advisors could determine not to use investment strategies that trigger additional regulation by the U.S. Commodity Futures Trading Commission, or the CFTC, or could determine to operate subject to CFTC regulation, if applicable. If we or GC Advisors were to operate subject to CFTC regulation, we could incur additional expenses and would be subject to additional regulation. On October 21, 2014, U.S. risk retention rules adopted pursuant to Section 941 of Dodd-Frank, or the U.S. Risk Retention Rules, were issued and became effective with respect to CLOs on December 24, 2016. The U.S. Risk Retention Rules require the sponsor (directly or through a majority-owned affiliate) of a debt securitization subject to such rules, such as CLOs, in the absence of an exemption, to retain an economic interest, or the Retention Interest, in the credit risk of the assets being securitized in the form of an eligible horizontal residual interest, an eligible vertical interest, or a combination thereof, in accordance with the requirements of the U.S. Risk Retention Rules. The U.S. Risk Retention Rules define the sponsor as the party that "organizes and initiates a securitization transaction by selling or transferring assets, either directly or indirectly, including through an affiliate." In the case of securitizations in which the assets being securitized are primarily transferred from the balance sheet of a corporate parent (or one or more subsidiaries or affiliates thereof), that corporate parent entity typically organizes and initiates the transaction in connection with such transfer and, therefore, would be considered a "sponsor" for U.S. Risk Retention Rules purposes. For purposes of this transaction, although the preamble to the rule text in the U.S. Risk Retention Rules suggests the collateral manager of a CLO would be the sponsor of such transaction, based upon the definition of "sponsor" in the U.S. Risk Retention Rules and the DC Circuit Court Decision, the Fund would be considered to be a "sponsor" as of the closing date, due to its direct and/or indirect transfer of assets to the 2023 Issuer (such indirect transfer inclusive, for the avoidance of doubt, of affiliates of the Fund selling assets to the 2023 Issuer) on and prior to the closing date. However, there can be no assurance, and no representation is made, that any governmental authority will agree that such is the case. It is possible that a change in interpretation of the U.S. Risk Retention Rules occurs following the closing date of the 2023 Debt Securitization such that the Fund would no longer qualify as the "sponsor" of this transaction, and instead an affiliate of the Fund (including GC Advisors or its affiliates) would be the appropriate sponsor. If such a change in interpretation occurs, the 2023 Depositor and/or GC Advisors may, but will have no obligation to, cause a transfer of the U.S. Retention Interest such that the "sponsor" and the U.S. Retention Provider will be in compliance with the U.S. Risk Retention Rules. The U.S. Risk Retention Rules provide that if there is more than one "sponsor" of a securitization transaction, each "sponsor" is to ensure that at least one "sponsor" (or its "majority-owned affiliate") retains the requisite U.S. Retention Interest. At this time, however, there are a number of unresolved questions, little regulatory guidance, and no established line of authority, precedent or market practice with respect to what is required to comply with the U.S. Risk Retention Rules in certain circumstances, and therefore there can be no assurance that the credit risk retention and disclosures contemplated herein will enable the U.S. Retention Provider to comply with the U.S. Risk Retention Rules. On February 9, 2018, the United States Court of Appeals for the District of Columbia ruled in favor of an appeal brought by the Loan Syndications and Trading Association (the "LSTA") and reversed a lower court decision in favor of the Securities and Exchange Commission and the Board of Governors of the Federal Reserve System with instructions to grant summary judgment in favor of the LSTA on the issue of whether the U.S. Risk Retention Rules apply to collateral managers of "open market" CLOs under Section 941 of the Dodd-Frank Act (the "DC Circuit Court Decision"). The DC Circuit Court Decision became effective on April 5, 2018. As of the date hereof, CLO managers of "open-market CLOs" (as defined in the DC Circuit Court Decision) will no longer be required to comply with the U.S. Risk Retention Rules. The collateral manager and the U.S. Retention Provider do not believe that this transaction is an "open-market CLO", due primarily to the fact that the collateral bbligations acquired by the Issuer are, and the additional collateral obligations to be acquired by the Issuer are expected to primarily or exclusively be, assets transferred, directly or indirectly, from the E.U./U.K. Retention Provider. As a result, the collateral manager and the U.S. Retention Provider believe that the U.S. Risk Retention Rules apply to this transaction. However, if the collateral manager and the U.S. Retention Provider were to conclude, on the basis of future guidance, evolving market practice or otherwise, that the BDC is not an appropriate "sponsor" and an affiliate of the BDC (including the collateral manager or its affiliates) would be an appropriate "sponsor," then the U.S. Retention Provider may, but will have no obligation to, transfer the U.S. Retention Interest to such affiliate or a majority-owned affiliate thereof, although there can be no assurance that such transfer will not be challenged by a regulatory authority or ultimately determined to be in violation of the U.S. Risk Retention Rules. If we ever determined that undertaking CLO transactions would subject us or any of our affiliates to unacceptable regulatory risk, our ability to execute CLOs could be limited or otherwise curtailed. Given the more attractive financing costs associated with these types of debt securitization as opposed to other types of financing available (such as traditional senior secured facilities), this would, in turn, increase our financing costs. Any associated increase in financing costs would ultimately be borne by our common shareholders. Over the last several years, there also has been an increase in regulatory attention to the extension of credit outside of the traditional banking sector, raising the possibility that some portion of the non-bank financial sector will be subject to new regulation. While it cannot be known at this time whether any regulation will be implemented or what form it will take, increased regulation of non-bank credit extension could negatively impact our operations, cash flows or financial condition, impose additional costs on us, intensify the regulatory supervision of us or otherwise adversely affect our business, financial condition and results of operations. We incur significant costs as a result of having securities registered under the Exchange Act. We incur legal, accounting and other expenses, including costs associated with the periodic reporting requirements applicable to a company whose securities are registered under the Exchange Act, as well as additional corporate governance requirements, including requirements under the Sarbanes-Oxley Act and other rules implemented by the SEC. We are an “emerging growth company,” and we do not know if such status will make our Common Shares less attractive to investors. We are an “emerging growth company,” as defined in the JOBS Act for up to five years, or until the earliest of: ● the last date of the fiscal year during which we had total annual gross revenues first exceed $1.235 billion; ● the last day of the fiscal year ending after the fifth anniversary of any initial public offering of our common stock; ● the date on which we have, during the previous three-year period, issued more than $1 billion in non-convertible debt; or ● the date on which we are deemed to be a “large accelerated filer” as defined under Rule 12b-2 under the Exchange Act. However, we are not likely to lose our status as an emerging growth company as a result of being deemed a “large accelerated filer” because there is not, and there is not expected to be, a public trading market for our Common Shares. As an emerging growth company, we are eligible to take advantage of some or all of the reduced regulatory and disclosure requirements permitted by the JOBS Act and, as a result, some investors could consider our common stock less attractive. For example, while we are an emerging growth company and/or a non-accelerated filer within the meaning of the Exchange Act, we can take advantage of an exemption from the provisions of Section 404(b) of the Sarbanes-Oxley Act requiring that our independent registered public accounting firm provide an attestation report on the effectiveness of our internal control over financial reporting. This could increase the risk that material weaknesses or other deficiencies in our internal control over financial reporting go undetected. Our compliance with the Sarbanes-Oxley Act involves significant expenditures, and non-compliance with Section 404 of the Sarbanes-Oxley Act would adversely affect us and the value of our Common Shares. We are subject to the Sarbanes-Oxley Act and the related rules and regulations promulgated by the SEC. Our management is required to report on our internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act and related rules and regulations of the SEC. As such, we are required to review on an annual basis our internal control over financial reporting, and on a quarterly and annual basis to evaluate and disclose changes in our internal control over financial reporting. As a result, we incur expenses that could negatively impact our financial performance and our ability to make distributions. This process also results in a diversion of management’s time and attention. We cannot ensure that our evaluation, testing and remediation process is effective or that our internal controls over financial reporting will be effective. In the event that we are unable to maintain compliance with Section 404 of the Sarbanes-Oxley Act and related rules, we and the net offering price of our securities would be adversely affected. We may invest through various joint ventures. From time to time, the Fund may hold a portion of its investments through partnerships, joint ventures, securitization vehicles or other entities with third-party investors (collectively, “joint ventures”). Joint venture investments involve various risks, including the risk that the Fund will not be able to implement investment decisions or exit strategies because of limitations on the Fund’s control under applicable agreements with joint venture partners, the risk that a joint venture partner may become bankrupt or may at any time have economic or business interests or goals that are inconsistent with those of the Fund, the risk that a joint venture partner may be in a position to take action contrary to the Fund’s objectives, the risk of liability based upon the actions of a joint venture partner and the risk of disputes or litigation with such partner and the inability to enforce fully all rights (or the incurrence of additional risk in connection with enforcement of rights) one partner may have against the other, including in connection with foreclosure on partner loans, because of risks arising under state law. In addition, the Fund may, in certain cases, be liable for actions of its joint venture partners. The joint venture’s in which we participate may sometimes be allocated investment opportunities that might have otherwise gone entirely to the Fund, which may reduce our return on equity. Additionally, our joint venture investments may be held on an unconsolidated basis and at times may be highly leveraged. Such leverage would not count toward the investment limits imposed on us by the 1940 Act. The Fund does not intend to create or acquire primary control of any entity that primarily engages in investment activities in securities and other assets other than joint ventures or entities wholly owned by the Fund. We are subject to risks associated with investing alongside other third parties. We invest in joint ventures alongside third parties through joint ventures, partnerships or other entities in the future. Such investments may involve risks not present in investments where a third party is not involved, including the possibility that such third party may at any time have economic or business interests or goals which are inconsistent with ours, or may be in a position to take action contrary to our investment objectives. In addition, we may in certain circumstances be liable for actions of such third party. More specifically, joint ventures involve a third party that has approval rights over activity of the joint venture. The third party may take actions that are inconsistent with our interests. For example, the third party may decline to approve an investment for the joint venture that we otherwise want the joint venture to make. A joint venture may also use investment leverage which magnifies the potential for gain or loss on amounts invested. Generally, the amount of borrowing by the joint venture is not included when calculating our total borrowing and related leverage ratios and is not subject to asset coverage requirements imposed by the 1940 Act. If the activities of the joint venture were required to be consolidated with our activities because of a change in GAAP rules or SEC staff interpretations, it is likely that we would have to reorganize any such joint venture. Technological innovations and industry disruptions could negatively impact us. Technological innovations have disrupted traditional approaches in multiple industries and can permit younger companies to achieve success and in the process disrupt markets and market practices. We can provide no assurance that new businesses and approaches will not be created that would compete with us and/or our portfolio companies or alter the market practices in which GC Advisors and its affiliates and us have been designed to function within and on which we depend on for our investment return. New approaches could damage our investments, disrupt the market in which we operate and subject us to increased competition, which could materially and adversely affect our business, financial condition and results of investments. We are highly dependent on information systems and systems failures could significantly disrupt our business, which could, in turn, negatively affect the value of our Common Shares and our ability to pay distributions. Our business depends on the communications and information systems of GC Advisors and its affiliates. GC Advisors and the Administrator are heavily reliant on the information technology infrastructure, processes and procedures of Golub Capital, which has devoted significant resources to developing effective and reliable information technology systems. Information technology changes rapidly, however, and Golub Capital could fail to stay ahead of such advances. Moreover, Golub Capital could find itself a target of cyberattacks, including cyber espionage, malware, ransomware, and other types of hacking. If any of the Golub Capital information technology systems do not operate properly or are disabled, whether as a result of tampering or a breach of network security systems or otherwise, we and Golub Capital could suffer, among other consequences, financial loss, disruption of businesses and reputational damage and, in the case of Golub Capital, liability to clients. While steps have been taken to mitigate the risk and impact of such attacks, no system is fully attack-proof, and a cyberattack could have an adverse impact on us. In addition, Golub Capital’s operations rely on the secure processing, storage and transmission of confidential and other information in its computer systems and networks. Although Golub Capital takes protective measures, its computer systems, software and networks could be vulnerable to unauthorized access, theft, misuse, computer viruses or other malicious code and other events that could have an impact on security. We, GC Advisors and the Administrator rely on third-party service providers for certain aspects of their business. Any interruption or deterioration in the performance of these third parties or failures of their information systems and technology could impair the quality of the operations and could affect their reputation, which could have an adverse effect on us. A data breach could negatively impact our business and result in significant penalties. GC Advisors is subject to numerous laws in various jurisdictions relating to privacy and the storage, sharing, use, processing, disclosure and protection of information that we and our affiliates hold. The EU’s General Data Protection Regulation, the Cayman Islands Data Protection Law, 2017, and the California Consumer Privacy Act of 2018 are recent examples of such laws, and GC Advisors anticipates new privacy and data protection laws will be passed in other jurisdictions in the future. In general, these laws introduce many new obligations on GC Advisors and its affiliates and service providers and create new rights for parties who have given us their personal information, such as investors and others. Breach of these laws could result in significant financial penalties for GC Advisors and/or us. As interpretation of these laws evolves and new laws are passed, GC Advisors could be required to make changes to its business practices, which could result in additional risks, costs and liabilities to us and adversely affect investment returns. While GC Advisors intends to comply with its privacy and data protection obligations under the privacy and data protection laws that are applicable to it, it is possible that GC Advisors will not be able to accurately anticipate the ways in which regulators and courts will apply or interpret these laws. A violation of applicable privacy and data protection law could result in negative publicity and/or subject GC Advisors or us to significant costs associated with litigation, settlements, regulatory action, judgments, liabilities and/or penalties. Cybersecurity risks and cyber incidents may adversely affect our business or the business of our portfolio companies. The operations of us, Golub Capital, any third-party service provider to us or Golub Capital and our portfolio companies are susceptible to risks from cybersecurity attacks and incidents due to reliance on the secure processing, storage and transmiss
