Organization, Consolidation and Presentation of Financial Statements [Abstract]
Formation and Business Purpose	Formation and Business Purpose New Mountain Guardian III BDC, L.L.C. (the "Company") is a Delaware limited liability company formed on May 22, 2019. The Company is a closed-end, non-diversified 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"). The Company has elected to be treated for U.S. federal income tax purposes, and intends to continue to comply with the requirements to qualify annually, as a regulated investment company ("RIC") under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"). New Mountain Finance Advisers, L.L.C. (the "Investment Adviser"), formerly known as New Mountain Finance Advisers BDC, L.L.C., is a wholly-owned subsidiary of New Mountain Capital Group, L.P. (together with New Mountain Capital, L.L.C. and its affiliates, "New Mountain Capital"), whose ultimate owners include Steven B. Klinsky, other current and former New Mountain Capital professionals and related vehicles and a minority investor. New Mountain Capital is a global investment firm with approximately $55 billion of assets under management and a track record of investing in the middle market. New Mountain Capital focuses on investing in defensive growth companies across its private equity, credit and net lease investment strategies. The Investment Adviser manages the Company's day-to-day operations and provides it with investment advisory and management services. The Investment Adviser also manages other funds that may have investment mandates that are similar, in whole or in part, to the Company's. New Mountain Finance Administration, L.L.C. (the "Administrator"), a wholly-owned subsidiary of New Mountain Capital, provides the administrative services necessary to conduct the Company's day-to-day operations. The Administrator has hired a third-party sub-administrator to assist with the provision of administrative services. The Company conducted a private offering (the "Private Offering") of units of the Company's limited liability company interests (the "Units"). Units were offered for subscription continuously throughout the Closing Period (as defined below). Each investor in the Private Offering made a capital commitment (each, a "Capital Commitment") to purchase Units pursuant to a subscription agreement entered into with the Company (each, a "Subscription Agreement"). Closings of the Private Offering occurred, from time to time, in the Investment Adviser's sole discretion, during the 18-month period following the initial closing of Capital Commitments, which occurred on July 15, 2019 (the "Closing Period"). Pursuant to the Limited Liability Company Agreement (as amended and restated on June 28, 2023, the "Fourth A&R LLC Agreement"), the Closing Period was previously extended to and ended on October 15, 2021. The Company accepted and drew down on Capital Commitments from investors throughout the Closing Period and drew down on Capital Commitments throughout the Investment Period (as defined below). At the end of the Closing Period, the Company had aggregate Capital Commitments from investors of $1,149,065. The Company commenced loan origination and investment activities contemporaneously with the initial drawdown from investors in the Private Offering (the "Initial Drawdown"), which occurred on August 2, 2019 (the "Initial Drawdown Date"). The "Investment Period" began on July 15, 2019 and ended on July 15, 2023, the four-year anniversary of such date. The term of the Company was initially until July 15, 2025, six years from the beginning of the Investment Period, subject to (i) a one-year extension (the six year period together with any successive extensions, the "Term") as determined by the Investment Adviser in its sole discretion and (ii) an additional one-year extension as determined by the Company's board of directors ("the Board"). Pursuant to the Fourth A&R LLC Agreement, the Investment Adviser extended the Term of the Company for an additional one-year period, to July 15, 2026. The Company established New Mountain Guardian III SPV, L.L.C. ("GIII SPV") as a wholly-owned direct subsidiary, whose assets are used to secure GIII SPV's credit facility. The Company established New Mountain Guardian III OEC, Inc. ("GIII OEC") as a wholly-owned direct subsidiary, which is treated as a corporation for U.S. federal income tax purposes and is intended to facilitate the Company's compliance with the requirements to be treated as a RIC under the Code by holding equity or equity-like investments in one of the Company's portfolio companies organized as a limited liability company (or other form of pass through entities). The Company consolidates this corporation for accounting purposes, but the corporation is not consolidated for U.S. federal income tax purposes, and may incur U.S. federal income tax expense as a result of its ownership of the portfolio company. The Company focuses on providing direct lending solutions to U.S. upper middle market companies backed by top private equity sponsors. The Company's investment objective is to generate current income and capital appreciation through the sourcing and origination of senior secured loans and select junior capital positions, to growing businesses in defensive industries that offer attractive risk-adjusted returns. The Company's differentiated investment approach leverages the deep sector knowledge and operating resources of New Mountain Capital. The Company primarily invests in senior secured debt of U.S. sponsor-backed, middle market companies. The Company defines middle market companies as those with annual earnings before interest, taxes, depreciation, and amortization ("EBITDA") between $10,000 and $200,000. The Company focuses on defensive growth businesses that generally exhibit the following characteristics: (i) acyclicality, (ii) sustainable secular growth drivers, (iii) niche market dominance and high barriers to competitive entry, (iv) recurring revenue and strong free cash flow, (v) flexible cost structures and (vi) seasoned management teams. Senior secured loans may include traditional first lien loans or unitranche loans. The Company invests a significant portion of its portfolio in unitranche loans, which are loans that combine both senior and subordinated debt, generally in a first-lien position. Because unitranche loans combine characteristics of senior and subordinated debt, they have risks similar to the risks associated with secured debt and subordinated debt. Certain unitranche loan investments may include “last-out” positions, which generally heighten the risk of loss. In some cases, the Company’s investments may also include equity interests. As of September 30, 2024, the Company's top five industry concentrations were software, healthcare, business services, consumer services and distribution & logistics.

Summary of Significant Accounti

Summary of Significant Accounting Policies	9 Months Ended

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of accounting —The Company's consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States ("GAAP"). The Company is an investment company following accounting and reporting guidance in Accounting Standards Codification Topic 946, Financial Services — Investment Companies ("ASC 946"). The Company consolidates its wholly-owned direct subsidiaries GIII SPV and GIII OEC. The Company's consolidated financial statements reflect all adjustments and reclassifications which, in the opinion of management, are necessary for the fair presentation of the results of operations and financial condition for the period(s) presented. All intercompany transactions have been eliminated. Revenues are recognized when earned and expenses when incurred. The financial results of the Company's portfolio investments are not consolidated in the financial statements. The Company's interim consolidated financial statements are prepared in accordance with GAAP and pursuant to the requirements for reporting on Form 10-Q and Articles 6 and 10 of Regulation S-X. Accordingly, the Company’s interim consolidated financial statements do not include all of the information and notes required by GAAP for annual financial statements. In the opinion of management, all adjustments, consisting solely of normal recurring accruals considered necessary for the fair presentation of financial statements for the interim period, have been included. The current period's results of operations will not necessarily be indicative of results that ultimately may be achieved for the fiscal year ending December 31, 2024. Investments —The Company applies fair value accounting in accordance with GAAP. Fair value is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Investments are reflected on the Company's Consolidated Statements of Assets, Liabilities and Members' Capital at fair value, with changes in unrealized gains and losses resulting from changes in fair value reflected in the Company's Consolidated Statements of Operations as "Net change in unrealized appreciation (depreciation) of investments" and realizations on portfolio investments reflected in the Company's Consolidated Statements of Operations as "Net realized gains (losses) on investments". The Company values its assets on a quarterly basis, or more frequently if required under the 1940 Act. In all cases, the Board is ultimately and solely responsible for determining the fair value of the Company's portfolio investments on a quarterly basis in good faith, including investments that are not publicly traded, those whose market prices are not readily available and any other situation where its portfolio investments require a fair value determination. Security transactions are accounted for on a trade date basis. The Company's quarterly valuation procedures are set forth in more detail below: (1) Investments for which market quotations are readily available on an exchange are valued at such market quotations based on the closing price indicated from independent pricing services. (2) Investments for which indicative prices are obtained from various pricing services and/or brokers or dealers are valued through a multi-step valuation process, as described below, to determine whether the quote(s) obtained is representative of fair value in accordance with GAAP. a. Bond quotes are obtained through independent pricing services. Internal reviews are performed by the investment professionals of the Investment Adviser to ensure that the quote obtained is representative of fair value in accordance with GAAP and, if so, the quote is used. If the Investment Adviser is unable to sufficiently validate the quote(s) internally and if the investment's par value or its fair value exceeds the materiality threshold, the investment is valued similarly to those assets with no readily available quotes (see (3) below); and b. For investments other than bonds, the Company looks at the number of quotes readily available and performs the following procedures: i. Investments for which two or more quotes are received from a pricing service are valued using the mean of the mean of the bid and ask of the quotes obtained. The Company will evaluate the reasonableness of the quote, and if the quote is determined to not be representative of fair value, the Company will use one or more of the methodologies outlined below to determine fair value; and ii. Investments for which one quote is received from a pricing service are validated internally. The investment professionals of the Investment Adviser analyze the market quotes obtained using an array of valuation methods (further described below) to validate the fair value. If the Investment Adviser is unable to sufficiently validate the quote internally and if the investment's par value or its fair value exceeds the materiality threshold, the investment is valued similarly to those assets with no readily available quotes (see (3) below). (3) Investments for which quotations are not readily available through exchanges, pricing services, brokers, or dealers are valued through a multi-step valuation process: a. Each portfolio company or investment is initially valued by the investment professionals of the Investment Adviser responsible for the credit monitoring; b. Preliminary valuation conclusions will then be documented and discussed with the Company's senior management; c. If an investment falls into (3) above for four consecutive quarters and if the investment's par value or its fair value exceeds the materiality threshold, then at least once each fiscal year, the valuation for each portfolio investment for which the Company does not have a readily available market quotation will be reviewed by an independent valuation firm engaged by the Board; and d. When deemed appropriate by the Company's management, an independent valuation firm may be engaged to review and value investment(s) of a portfolio company, without any preliminary valuation being performed by the Investment Adviser. The investment professionals of the Investment Adviser will review and validate the value provided. For investments in revolving credit facilities and delayed draw commitments, the cost basis of the funded investments purchased is offset by any costs/netbacks received for any unfunded portion on the total balance committed. The fair value is also adjusted for the price appreciation or depreciation on the unfunded portion. As a result, the purchase of a commitment not completely funded may result in a negative fair value until it is called and funded. The values assigned to investments are based upon available information and do not necessarily represent amounts which might ultimately be realized, since such amounts depend on future circumstances and cannot be reasonably determined until the individual positions are liquidated. Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of the Company's investments may fluctuate from period to period and the fluctuations could be material. See Note 3. Investments , for further discussion relating to investments. Cash and cash equivalents —Cash and cash equivalents include cash and short-term, highly liquid investments. The Company defines cash equivalents as securities that are readily convertible into known amounts of cash and so near maturity that there is insignificant risk of changes in value. These securities have original maturities of three months or less. The Company did not hold any cash equivalents as of September 30, 2024 and December 31, 2023. Revenue recognition Sales and paydowns of investments: Realized gains and losses on investments are determined on the specific identification method. Interest and dividend income: Interest income, including amortization of premium and discount using the effective interest method, is recorded on the accrual basis and periodically assessed for collectability. Interest income also includes interest earned from cash on hand. Upon the prepayment of a loan or debt security, any prepayment penalties are recorded as part of interest income. The Company has loans and certain preferred equity investments in its portfolio that contain a payment-in-kind ("PIK") interest or dividend provision. PIK interest and dividends are accrued and recorded as income at the contractual rates, if deemed collectible. The PIK interest and dividends are added to the principal or share balances on the capitalization dates and are generally due at maturity or when redeemed by the issuer. For the three and nine months ended September 30, 2024, the Company recognized PIK interest from investments of $3,498 and $11,326, respectively, and PIK dividends from investments of $2,231 and $7,259, respectively. For the three and nine months ended September 30, 2023, the Company recognized PIK interest from investments of $3,036 and $8,427, respectively, and PIK dividends from investments of $2,482 and $7,206, respectively. Dividend income on preferred securities is recorded as dividend income on an accrual basis to the extent that such amounts are deemed collectible. Non-accrual income: Investments are placed on non-accrual status when principal or interest payments are past due for 30 days or more and when there is reasonable doubt that principal or interest will be collected. Accrued cash and un-capitalized PIK interest or dividends are reversed when an investment is placed on non-accrual status. Previously capitalized PIK interest or dividends are not reversed when an investment is placed on non-accrual status. Interest or dividend payments received on non-accrual investments may be recognized as income or applied to principal depending upon management's judgment of the ultimate collectability. Non-accrual investments are restored to accrual status when past due principal and interest is paid and, in management's judgment, are likely to remain current. As of September 30, 2024 and December 31, 2023, no investments were on non-accrual status. Fee income: Fee income represents delayed compensation, amendment fees, revolver fees and other miscellaneous fees received and are typically non-recurring in nature. Delayed compensation is income earned from counterparties on trades that do not settle within a set number of business days after the trade date. Fee income may also include fees from bridge loans. The Company may from time to time enter into bridge financing commitments, an obligation to provide interim financing to a counterparty until permanent credit can be obtained. These commitments are short-term in nature and may expire unfunded. A fee is received by the Company for providing such commitments. Structuring fees and upfront fees are recognized as income when earned, usually when paid at the closing of the investment, and are non-refundable. Interest and other financing expenses —Interest and other financing fees are recorded on an accrual basis by the Company. See Note 6. Borrowings , for details. Organizational expenses —Organizational expenses include costs and expenses incurred in connection with the formation and organization of the Company and are expensed as incurred in the Consolidated Statements of Operations. Any organizational and offering expenses paid by the Company in excess of the lesser of $2,000 or 0.50% of the aggregate Capital Commitments will be applied as a reduction to the base management fee paid to the Investment Adviser and cannot be recouped by the Investment Adviser. Deferred financing costs —The deferred financing costs of the Company consist of capitalized expenses related to the origination and amending of the Company's borrowings. The Company amortizes these costs into expense over the stated life of the related borrowing. See Note 6. Borrowings , for details. Income taxes —The Company has elected to be treated as a RIC for U.S. federal income tax purposes under Subchapter M of the Code and intends to comply with the requirements to qualify and maintain its status as a RIC annually. As a RIC, the Company is not subject to U.S. federal income tax on the portion of taxable income and gains timely distributed to its unitholders. To continue to qualify and be subject to tax treatment as a RIC, the Company is required to meet certain income and asset diversification tests in addition to timely distributing at least 90.0% of its investment company taxable income, as defined by the Code. Since U.S. federal income tax regulations differ from GAAP, distributions in accordance with tax regulations may differ from net investment income and realized gains recognized for financial reporting purposes. Differences between taxable income and the results of operations for financial reporting purposes may be permanent or temporary in nature. Permanent differences are reclassified among capital accounts in the consolidated financial statements to reflect their tax character. Differences in classification may also result from the treatment of short-term gains as ordinary income for U.S. federal income tax purposes. For U.S. federal income tax purposes, distributions paid to unitholders of the Company are reported as ordinary income, return of capital, long term capital gains or a combination thereof. The Company will be subject to a 4.0% nondeductible federal excise tax on certain undistributed income unless the Company distributes, in a timely manner as required by the Code, an amount at least equal to the sum of (1) 98.0% of its respective net ordinary income earned for the calendar year and (2) 98.2% of its respective capital gain net income for the one-year period ending October 31 in the calendar year. Certain consolidated subsidiaries of the Company are subject to U.S. federal and state income taxes. These taxable entities are not consolidated for U.S. federal income tax purposes and may generate income tax liabilities or assets from permanent and temporary differences in the recognition of items for financial reporting and U.S. federal income tax purposes. The following table summarizes the total income tax provision, income tax expense and deferred income tax provision for the three and nine months ended September 30, 2024 and September 30, 2023: Three Months Ended Nine Months Ended September 30, 2024 September 30, 2023 September 30, 2024 September 30, 2023 Deferred income tax (benefit) provision $ (1) $ (833) $ 145 $ (686) Current income tax (benefit) expense (4) (1,402) 383 813 Total income tax (benefit) provision $ (5) $ (2,235) $ 528 $ 127 As of September 30, 2024 and December 31, 2023, the Company had $6 and $150, respectively, of deferred tax assets primarily relating to deferred taxes attributable to certain differences between the computation of income for U.S. federal income tax purposes as compared to GAAP. Based on its analysis, the Company has determined that there were no uncertain tax positions that do not meet the more likely than not threshold as defined by Accounting Standards Codification Topic 740, Income Taxes (“ASC 740”) through December 31, 2023. The 2019 through 2023 tax years and forward remain subject to examination by the U.S. federal, state, and local tax authorities. Distributions —Distributions to the Company's unitholders are recorded on the record date as set by the Board. The Company intends to make timely distributions to its unitholders that will be sufficient to enable the Company to qualify and maintain its status as a RIC. The Company intends to distribute approximately all of its net investment income on a quarterly basis and substantially all of its taxable income on an annual basis, except that the Company may retain certain net capital gains for reinvestment. Earnings per Unit —The Company's earnings per unit ("EPU") amounts have been computed based on the weighted-average number of Units outstanding for the period. Basic EPU is computed by dividing net increase (decrease) in members' capital resulting from operations by the weighted average number of Units outstanding during the period of computation. Diluted EPU is computed by dividing net increase (decrease) in members' capital resulting from operations by the weighted average number of Units assuming all potential Units had been issued, and its related net impact to members' capital accounted for, and the additional Units were dilutive. Diluted EPU reflects the potential dilution, using the as-if-converted method for convertible debt, which could occur if all potentially dilutive securities were exercised. Foreign securities —The accounting records of the Company are maintained in U.S. dollars. Investment securities denominated in foreign currencies are translated into U.S. dollars based on the rate of exchange of such currencies on the date of valuation. Purchases and sales of investment securities and income and expense items denominated in foreign currencies are translated into U.S. dollars based on the rate of exchange of such currencies on the respective dates of the transactions. The Company does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with "Net change in unrealized appreciation (depreciation) of investments" and "Net realized gains (losses) on investments" in the Company's Consolidated Statements of Operations. Investments denominated in foreign currencies may be negatively affected by movements in the rate of exchange between the U.S. dollar and such foreign currencies. This movement is beyond the control of the Company and cannot be predicted. Use of estimates —The preparation of the Company's consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the Company's consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Changes in the economic environment, financial markets, and other metrics used in determining these estimates could cause actual results to differ from the estimates used, and the differences could be material.

Commitments and Contingencies . Investment Risk Factors —First and second lien debt that the Company invests in is almost entirely rated below investment grade or may be unrated. Debt investments rated below investment grade are often referred to as "leveraged loans", "high yield" or "junk" debt investments, and may be considered "high risk" compared to debt investments that are rated investment grade. These debt investments are considered speculative because of the credit risk of the issuers. Such issuers are considered more likely than investment grade issuers to default on their payments of interest and principal, and such risk of default could reduce the members' capital and income distributions of the Company. In addition, some of the Company's debt investments will not fully amortize during their lifetime, which could result in a loss or a substantial amount of unpaid principal and interest due upon maturity. First and second lien debt may also lose significant market value before a default occurs. Furthermore, an active trading market may not exist for these first and second lien debt investments. This illiquidity may make it more difficult to value the debt. Subordinated debt is generally subject to similar risks as those associated with first and second lien debt, except that such debt is subordinated in payment and/or lower in lien priority. Subordinated debt is subject to the additional risk that the cash flow of the borrower and the property securing the debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured and unsecured obligations of the borrower. The Company may directly invest in the equity of private companies or, in some cases, equity investments could be made in connection with a debt investment. Equity investments may or may not fluctuate in value, resulting in recognized realized gains or losses upon disposition.

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Pursuant to Rule 2a-5 under the 1940 Act, a market quotation is readily available for purposes of Section 2(a)(41) of the 1940 Act with respect to a security only when that "quotation is a quoted price (unadjusted) in active markets for identical investments that the fund can access at the measurement date, provided that a quotation will not be readily available if it is not reliable." Fair value is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosure ("ASC 820") establishes a fair value hierarchy that prioritizes and ranks the inputs to valuation techniques used in measuring investments at fair value. The hierarchy classifies the inputs used in measuring fair value into three levels as follows: Level I —Quoted prices (unadjusted) are available in active markets for identical investments and the Company has the ability to access such quotes as of the reporting date. The type of investments which would generally be included in Level I include active exchange-traded equity securities and exchange-traded derivatives. As required by ASC 820, the Company, to the extent that it holds such investments, does not adjust the quoted price for these investments, even in situations where the Company holds a large position and a sale could reasonably impact the quoted price. Level II —Pricing inputs are observable for the investments, either directly or indirectly, as of the reporting date, but are not the same as those used in Level I. Level II inputs include the following: • Quoted prices for similar assets or liabilities in active markets; • Quoted prices for identical or similar assets or liabilities in non-active markets (examples include corporate and municipal bonds, which trade infrequently); • Pricing models whose inputs are observable for substantially the full term of the asset or liability (examples include most over-the-counter derivatives, including foreign exchange forward contracts); and • Pricing models whose inputs are derived principally from or corroborated by observable market data through correlation or other means for substantially the full term of the asset or liability. Level III —Pricing inputs are unobservable for the investment and include situations where there is little, if any, market activity for the investment. The inputs used to measure fair value may fall into different levels. In all instances when the inputs fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level of input that is significant to the fair value measurement in its entirety. As such, a Level III fair value measurement may include inputs that are both observable and unobservable. Gains and losses for such assets categorized within the Level III table below may include changes in fair value that are attributable to both observable inputs and unobservable inputs. The inputs into the determination of fair value require significant judgment or estimation by management and consideration of factors specific to each investment. A review of the fair value hierarchy classifications is conducted on a quarterly basis. Changes in the observability of valuation inputs may result in the transfer of certain investments within the fair value hierarchy from period to period. The following table summarizes the levels in the fair value hierarchy that the Company's portfolio investments fell into as of September 30, 2024: Total Level I Level II Level III First lien $ 1,269,788 $ — $ 1,818 $ 1,267,970 Second lien 147,279 — 53,490 93,789 Subordinated 37,712 — 948 36,764 Equity and other 83,880 — — 83,880 Total investments $ 1,538,659 $ — $ 56,256 $ 1,482,403 The following table summarizes the levels in the fair value hierarchy that the Company's portfolio investments fell into as of December 31, 2023: Total Level I Level II Level III First lien $ 1,557,172 $ — $ 1,938 $ 1,555,234 Second lien 299,332 — 29,566 269,766 Subordinated 35,939 — 859 35,080 Equity and other 98,902 — — 98,902 Total investments $ 1,991,345 $ — $ 32,363 $ 1,958,982 The following table summarizes the changes in fair value of Level III portfolio investments for the three months ended September 30, 2024, as well as the portion of appreciation (depreciation) included in income attributable to the net change in unrealized appreciation (depreciation) related to those assets and liabilities still held by the Company at September 30, 2024: Total First Lien Second Lien Subordinated Equity and other Fair Value, June 30, 2024 $ 1,584,506 $ 1,309,482 $ 156,739 $ 36,420 $ 81,865 Total gains or losses included in earnings: Net realized gains (losses) on investments 2 2 — — — Net change in unrealized appreciation (depreciation) of investments (8,319) (7,642) (750) 154 (81) Purchases, including capitalized PIK and revolver fundings 14,535 11,909 — 530 2,096 Proceeds from sales and paydowns of investments (66,251) (43,911) (22,000) (340) — Transfers out of Level III(1) (42,070) (1,870) (40,200) — — Fair Value, September 30, 2024 $ 1,482,403 $ 1,267,970 $ 93,789 $ 36,764 $ 83,880 Net change in unrealized appreciation (depreciation) for the period relating to those Level III assets that were still held by the Company at the end of the period: $ (8,317) $ (7,641) $ (750) $ 154 $ (80) (1) As of September 30, 2024, portfolio investments were transferred out of Level III into Level II at fair value as of the beginning of the period in which the reclassification occurred.

Except as noted in the tables above, there were no other transfers in or out of Levels I, II, or III during the three and nine months ended September 30, 2024 and September 30, 2023. Transfers into Level III occur as quotations obtained through pricing services are deemed not representative of fair value as of the balance sheet date, and such assets are internally valued. As quotations obtained through pricing services are substantiated through additional market sources, investments are transferred out of Level III. In addition, transfers out of Level III and transfers into Level III occur based on the increase or decrease in the availability of certain observable inputs. Investments will be transferred into Level III from Level II and out of Level III into Level II at fair value as of the beginning of the period in which the reclassification occurred. The Company invests in revolving credit facilities. These investments are categorized as Level III investments as these assets are not actively traded and their fair values are often implied by the term loans of the respective portfolio companies. The Company generally uses the following framework when determining the fair value of investments where there are little, if any, market activity or observable pricing inputs. The Company typically determines the fair value of its performing debt investments utilizing an income approach. Additional consideration is given using a market based approach, as well as reviewing the overall underlying portfolio company's performance and associated financial risks. The following outlines additional details on the approaches considered: Company Performance, Financial Review, and Analysis: Prior to investment, as part of its due diligence process, the Company evaluates the overall performance and financial stability of the portfolio company. Post investment, the Company analyzes each portfolio company's current operating performance and relevant financial trends versus prior year and budgeted results, including, but not limited to, factors affecting its revenue and EBITDA growth, margin trends, liquidity position, covenant compliance and changes to its capital structure. The Company also attempts to identify and subsequently track any developments at the portfolio company within its customer or vendor base, or within the industry or the macroeconomic environment generally, that may alter any material element of its original investment thesis. This analysis is specific to each portfolio company. The Company leverages the knowledge gained from its original due diligence process, augmented by this subsequent monitoring, to continually refine its outlook for each of its portfolio companies and ultimately form the valuation of its investment in each portfolio company. When an external event such as a purchase transaction, public offering or subsequent sale occurs, the Company will consider the pricing indicated by the external event to corroborate the private valuation. For debt investments, the Company may employ the Market Based Approach (as described below) to assess the total enterprise value of the portfolio company, in order to evaluate the enterprise value coverage of the Company's debt investment. For equity investments or in cases where the Market Based Approach implies a lack of enterprise value coverage for the debt investment, the Company may additionally employ a discounted cash flow analysis based on the free cash flows of the portfolio company to assess the total enterprise value. After enterprise value coverage is demonstrated for the Company's debt investments through the method(s) above, the Income Based Approach (as described below) may be employed to estimate the fair value of the investment. Market Based Approach: The Company may estimate the total enterprise value of each portfolio company by utilizing EBITDA or revenue multiples of publicly traded comparable companies and comparable transactions. The Company considers numerous factors when selecting the appropriate companies whose trading multiples are used to value its portfolio companies. These factors include, but are not limited to, the type of organization, similarity to the business being valued, and relevant risk factors, as well as size, profitability and growth expectations. The Company may apply an average of various relevant comparable company EBITDA or revenue multiples to the portfolio company's latest twelve month ("LTM") EBITDA or revenue or projected EBITDA or revenue to calculate the enterprise value of the portfolio company. Significant increases or decreases in the EBITDA or revenue multiples will result in an increase or decrease in enterprise value, which may result in an increase or decrease in the fair value estimate of the investment. In applying the market based approach as of September 30, 2024 and December 31, 2023, the Company used the relevant EBITDA or revenue multiple ranges set forth in the table below to determine the enterprise value of its portfolio companies. The Company believes these were reasonable ranges in light of current comparable company trading levels and the specific portfolio companies involved. Income Based Approach: The Company also may use a discounted cash flow analysis to estimate the fair value of the investment. Projected cash flows represent the relevant security's contractual interest, fee and principal payments plus the assumption of full principal recovery at the investment's expected maturity date. These cash flows are discounted at a rate established utilizing a combination of a yield calibration approach and a comparable investment approach. The yield calibration approach incorporates changes in the credit quality (as measured by relevant statistics) of the portfolio company, as compared to changes in the yield associated with comparable credit quality market indices, between the date of origination and the valuation date. The comparable investment approach utilizes an average yield-to-maturity of a selected set of high-quality, liquid investments to determine a comparable investment discount rate. Significant increases or decreases in the discount rate would result in a decrease or increase in the fair value measurement. In applying the income based approach as of September 30, 2024 and December 31, 2023, the Company used the discount ranges set forth in the table below to value investments in its portfolio companies. The unobservable inputs used in the fair value measurement of the Company's Level III investments as of September 30, 2024 were as follows: Range Type Fair Value as of September 30, 2024 Approach Unobservable Input Low High Weighted First lien $ 1,237,583 Market & income approach EBITDA multiple 8.0x 32.0x 17.0x Revenue multiple 4.5x 19.5x 9.2x Discount rate 7.2 % 21.1 % 10.1 % 30,387 Other N/A (2) N/A N/A N/A Second lien 93,789 Market & income approach EBITDA multiple 21.0x 21.0x 21.0x Discount rate 9.6 % 12.1 % 10.3 % Subordinated 36,764 Market & income approach EBITDA multiple 8.0x 24.5x 21.0x Discount rate 12.2 % 15.4 % 13.1 % Equity and other 83,880 Market & income approach EBITDA multiple 6.0x 32.0x 14.9x Revenue multiple 4.5x 19.5x 6.6x Discount rate 8.6 % 16.5 % 12.0 % $ 1,482,403 (1) Unobservable inputs were weighted by the relative fair value of the investments.

The GS Credit Facility (as defined below) and the Unsecured Notes (as defined below) are considered Level III investments. See Note 6. Borrowings for details. The following are the principal amounts and fair values of the Company’s borrowings as of September 30, 2024 and December 31, 2023. Fair value is estimated by discounting remaining payments using applicable current market rates, which take into account changes in the Company’s marketplace credit ratings, or market quotes, if available.

Related Party Transactions [Abstract]
Agreements and Related Parties	Agreements and Related Parties The Company entered into an investment advisory and management agreement (the “Investment Management Agreement") with the Investment Adviser, which was most recently re-approved by the Board on January 30, 2024, at an in-person meeting, for a period of 12 months commencing on March 1, 2024. Under the Investment Management Agreement, the Investment Adviser manages the day-to-day operations of, and provides investment advisory services to, the Company. For providing these services, the Investment Adviser receives an annual base management fee and incentive fee from the Company. Pursuant to the Investment Management Agreement, the base management fee is payable quarterly in arrears at an annual rate of 1.15% of the aggregate contributed capital from all unitholders (including any outstanding borrowings under any subscription line drawn in lieu of capital calls) less any return of capital distributions and less any cumulative realized losses since inception (calculated net of any subsequently reversed realized losses and net of any realized gains) as of the last day of the applicable quarter. The base management fee could also be reduced by any voluntary fee waivers made by the Investment Adviser. The management fee will be reduced, but not below zero, by any amounts paid by the Company or its subsidiaries to a placement agent, any organizational and offering expenses in excess of the lesser of $2,000 or 0.50% of the aggregate Capital Commitments and any fund expenses in excess of the Specified Expenses Cap (as defined below). 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. Incentive Fee on Pre-Incentive Fee Net Investment Income The portion based on the Company's income (the "Income Incentive Fee") is based on pre-incentive fee net investment income ("Pre-Incentive Fee Net Investment Income"). Pre-Incentive Fee Net Investment Income means interest income, dividend income and any fee income (including any other fees (other than fees for providing managerial assistance), such as commitment, origination, structuring, upfront, diligence and consulting fees or other fees that the Company receives from portfolio companies) accrued during the calendar quarter, minus the Company's operating expenses for the quarter (including the management fee, expenses payable under the Administration Agreement (as defined below), and any interest expense and distributions paid on any issued and outstanding preferred units, but excluding the incentive fee). Pre-Incentive Fee Net Investment Income includes, 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 we have not yet received in cash. Pre-Incentive Fee Net Investment Income does not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation. Pre-Incentive Fee Net Investment Income, expressed as a rate of return on the value of the Company's members' capital at the end of the immediately preceding quarter, is compared to a "hurdle rate" of return of 1.75% per quarter (7.0% annualized). The Company will pay the Investment Adviser an incentive fee quarterly in arrears with respect to the Company's Pre-Incentive Fee Net Investment Income in each calendar quarter as follows: • no incentive fee based on Pre-Incentive Fee Net Investment Income in any calendar quarter in which the Company's Pre-Incentive Fee Net Investment Income does not exceed the hurdle rate of 1.75% (7.0% annualized); • 100% of the dollar amount of our Pre-Incentive Fee Net Investment Income with respect to that portion of such Pre-Incentive Fee Net Investment Income, if any, that exceeds the hurdle rate but is less than or equal to a rate of return of 2.059% (8.235% annualized). The Company refers to this portion of the Company's Pre-Incentive Fee Net Investment Income (which exceeds the hurdle rate but is less than 2.059%) as the "catch-up." The "catch-up" is meant to provide the Investment Adviser with approximately 15.0% of the Company's Pre-Incentive Fee Net Investment Income as if a hurdle rate did not apply if this net investment income exceeds 2.059% in any calendar quarter; and • 15.0% of the dollar amount of the Company's Pre-Incentive Fee Net Investment Income, if any, that exceeds a rate of return of 2.059% (8.235% annualized). This reflects that once the hurdle rate is reached and the catch-up is achieved, 15.0% of all Pre-Incentive Fee Net Investment Income thereafter is allocated to the Investment Adviser. For the three and nine months ended September 30, 2024 and September 30, 2023, there were no incentive fees waived. The fees that are payable under the Investment Management Agreement for any partial period will be appropriately prorated. Incentive Fee on Capital Gains The second component of the incentive fee is the capital gains incentive fee. The Company will pay the Investment Adviser an incentive fee with respect to the Company's cumulative realized capital gains computed net of all realized capital losses and unrealized capital depreciation since inception ("Cumulative Net Realized Gains") based on the waterfall below: a. First, no incentive fee is payable to the Investment Adviser on Cumulative Net Realized Gains until total return of capital distributions, distributions of net investment income and distributions of net realized capital gains to unitholders is equal to total capital contributions; b. Second, no incentive fee is payable to the Investment Adviser on Cumulative Net Realized Gains until the Company has paid cumulative distributions equal to an annualized, cumulative internal rate of return of 7.0% on the total contributed capital to the Company calculated from the date that each such amount was due to be contributed to the Company until the date each such distribution is paid; c. Third, upon a distribution that results in cumulative distributions exceeding the amounts in clause (a) and (b) above, an incentive fee on capital gains payable to the Investment Adviser equal to 100.0% of the amount of Cumulative Net Realized Gains until the Investment Adviser has received (together with amounts the Investment Adviser has received under Income Incentive Fees) an amount equal to 15.0% of the sum of (i) the cumulative distributions to unitholders made pursuant to clause (b) above, (ii) Income Incentive Fee paid to the Investment Adviser, and (iii) amounts paid to the Investment Adviser pursuant to this clause (c); and d. Thereafter, an incentive fee on capital gains equal to 15.0% of additional undistributed Cumulative Net Realized Gains. Upon termination of the Company, the Investment Adviser will be required to return incentive fees to the Company to the extent that: (i) the Investment Adviser has received cumulative incentive fees in excess of 15.0% of the sum of (A) the Company's cumulative distributions other than return of capital contributions and (B) the cumulative incentive fees paid to the Investment Adviser; or (ii) the unitholders have not received a 7.0% cumulative internal rate of return; provided that in no event will such restoration be more than the incentive fees received by the Investment Adviser. In accordance with GAAP, the Company accrues a hypothetical capital gains incentive fee based upon the cumulative net realized capital gains and realized capital losses and the cumulative net unrealized capital appreciation and unrealized capital depreciation on investments held at the end of each period. The accrual for any capital gains incentive fee under GAAP in a given period may result in additional expense if such cumulative amount is greater than in the prior period or a reduction of previously recorded expense if such cumulative amount is less than the amount in the prior period. If such cumulative amount is negative, then there is no such accrual. Actual amounts paid to the Investment Adviser are consistent with the Investment Management Agreement and are based only on realized capital gains computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis from inception through the end of each calendar year. Expense Limitation Notwithstanding the foregoing, the Investment Adviser has agreed to reduce and/or waive its management fee (the "Specified Expenses Cap") each year such that the Company will not be required to pay Specified Expenses (as defined below) in excess of a maximum aggregate amount in any calendar year (prorated for partial years and portions of years for which each applicable prong of the cap applies) equal to: (1) during the Closing Period, 0.40% of the greater of (A) $750,000 or (B) actual aggregate Capital Commitments as of the end of such calendar year, (2) at the end of the Closing Period until the end of the Investment Period, 0.40% of aggregate committed capital and (3) after the end of the Investment Period, 0.40% of the Company's average Members' Capital for the calendar year. Further, if the actual Capital Commitments of the Company at the end of the Closing Period are less than $750,000, the prong of the Specified Expenses Cap in clause (1) above will be retroactively adjusted to equal 0.40% of aggregate committed capital at the end of the Closing Period, and the Investment Adviser has agreed to further reduce and/or waive its management fee for the year in which the Closing Period ends in an amount equal to the difference between (A) the amount that would have been required to be waived/reimbursed pursuant to clause (1) above as adjusted and (B) the amount previously waived/reimbursed pursuant to clause (1) above. "Specified Expenses" of the Company means all Company Expenses (as defined in the Fourth A&R LLC Agreement) incurred in the operation of the Company with the exception of: (i) the management fee, (ii) any incentive fees, (iii) Organizational and Offering Expenses (as defined under "Fund Expenses" in the Fourth A&R LLC Agreement) (which are subject to the Organizational and Offering Expenses Cap), (iv) Placement Fees (as defined in the Fourth A&R LLC Agreement), (v) interest on and fees and expenses arising out of all Company indebtedness and other financing, (vi) costs of any litigation and damages (including the costs of any indemnity or contribution right granted to any placement agent or third-party finder engaged by the Company or its affiliates) and (vii) for the avoidance of doubt, if applicable, any investor level withholding or other taxes. If, while the Investment Adviser is the investment adviser to the Company, the annualized Specified Expenses for a given calendar year are less than the Specified Expenses Cap, the Investment Adviser shall be entitled to reimbursement by the Company of the compensation waived and other expenses borne by the Investment Adviser (the "Reimbursement Amount") on behalf of the Company pursuant to the expense limitation and reimbursement agreement between the Company and the Investment Adviser (the "Expense Limitation and Reimbursement Agreement") during any of the previous thirty-six months, and provided that such amount paid to the Investment Adviser will in no event exceed the total Reimbursement Amount and will not include any amounts previously reimbursed. The Reimbursement Amount plus the annualized Specified Expenses for a given calendar year shall not exceed the Specified Expenses Cap. The Investment Adviser may recapture a Specified Expense in any year within the thirty-six month period after the Investment Adviser bears the expense. For the three and nine months ended September 30, 2024 and September 30, 2023, there were no reimbursements to the Investment Adviser pursuant to this provision. The Expense Limitation and Reimbursement Agreement may be amended by mutual agreement of the parties, provided that any amendment that could result in an increase in expenses borne by the Company also must be approved by vote of a majority of the Company's outstanding Units. The following table summarizes the management fees and incentive fees incurred by the Company for the three and nine months ended September 30, 2024 and September 30, 2023. Three Months Ended Nine Months Ended September 30, 2024 September 30, 2023 September 30, 2024 September 30, 2023 Management fee $ 2,547 $ 3,299 8,385 9,897 Less: management fee waiver — — (168) — Net management fee 2,547 3,299 8,217 9,897 Incentive fee, excluding accrued incentive fees on capital gains $ 4,106 $ 6,468 $ 14,943 18,058 As of September 30, 2024 and December 31, 2023, no incentive fee on capital gains was accrued or owed under the Investment Management Agreement by the Company, as Cumulative Net Realized Capital Gains was less than zero. The Company has entered into an administration agreement with the Administrator (as amended and restated, the "Administration Agreement") under which the Administrator provides administrative services. The Administration Agreement was most recently re-approved by the Board on January 30, 2024 for a period of 12 months commencing on March 1, 2024. The Administrator maintains, or oversees the maintenance of, the Company's consolidated financial records, prepares reports filed with the U.S. Securities and Exchange Commission (the "SEC"), generally monitors the payment of the Company's expenses and oversees the performance of administrative and professional services rendered by others. The Administrator has hired a third-party sub-administrator to assist with the provision of administrative services. The Company reimburses the Administrator for the Company's allocable portion of overhead and other expenses incurred by the Administrator in performing its obligations to the Company under the Administration Agreement, including compensation of the Company's chief financial officer and chief compliance officer, and their respective staffs. Pursuant to the Administration Agreement and further restricted by the Company, the Administrator may, in its own discretion, submit to the Company for reimbursement some or all of the expenses that the Administrator has incurred on behalf of the Company during any quarterly period. As a result, the amount of expenses for which the Company will have to reimburse the Administrator may fluctuate in future quarterly periods and there can be no assurance given as to when, or if, the Administrator may determine to limit the expenses that the Administrator submits to the Company for reimbursement in the future. The Administrator cannot recoup any expenses that the Administrator has previously waived. For the three and nine months ended September 30, 2024, approximately $230 and $695, respectively, of indirect administrative expenses were included in administrative expenses, none of which were waived by the Administrator. For the three and nine months ended September 30, 2023, approximately $309 and $702, respectively, of indirect administrative expenses were included in administrative expenses, none of which were waived by the Administrator. As of September 30, 2024 and December 31, 2023, approximately $230 and $356, respectively, of indirect administrative expenses were included in payable to affiliates. The Company, the Investment Adviser and the Administrator have also entered into a Trademark License Agreement (as amended, the "Trademark License Agreement"), with New Mountain Capital, pursuant to which New Mountain Capital has agreed to grant the Company, the Investment Adviser and the Administrator a non-exclusive, royalty-free license to use the "New Mountain Capital" name. Under the Trademark License Agreement, subject to certain conditions, the Company, the Investment Adviser and the Administrator will have a right to use the "New Mountain Capital" name, for so long as the Investment Adviser or one of its affiliates remains the investment adviser of the Company. Other than with respect to this limited license, the Company, the Investment Adviser and the Administrator will have no legal right to the "New Mountain Capital" name. The Investment Adviser and its affiliates may also manage other funds in the future that may have investment mandates that are similar, in whole or in part, to the Company's investment mandate. The Investment Adviser and its affiliates may determine that an investment is appropriate for the Company or for one or more of those other funds. In such event, depending on the availability of such investment and other appropriate factors, the Investment Adviser or its affiliates may determine that the Company should invest side-by-side with one or more other funds. Any such investments will be made only to the extent permitted by applicable law and interpretive positions of the SEC and its staff and consistent with the Investment Adviser's allocation procedures. On October 8, 2019, the SEC issued an exemptive order (the "Exemptive Order") to the Investment Adviser and certain of its affiliates, which superseded a prior order issued on December 18, 2017, which permits the Company to co-invest in portfolio companies with certain funds or entities managed by the Investment Adviser or its affiliates in certain negotiated transactions where co-investing would otherwise be prohibited under the 1940 Act, subject to the conditions of the Exemptive Order. Pursuant to the Exemptive Order, the Company is permitted to co-invest with its affiliates if a "required majority" (as defined in Section 57(o) of the 1940 Act) of the Company's directors who are not "interested persons", as that term is defined in Section 2(a)(19) of the 1940 Act (the "Independent Directors"), make certain conclusions in connection with a co-investment transaction, including, but not limited to, that (1) the terms of the potential co-investment transaction, including the consideration to be paid, are reasonable and fair to the Company and its unitholders and do not involve overreaching in respect of the Company or its unitholders on the part of any person concerned, and (2) the potential co-investment transaction is consistent with the interests of the Company's unitholders and is consistent with its then-current investment objective and strategies. In addition, pursuant to an exemptive order issued by the SEC on April 8, 2020 and applicable to all BDCs through December 31, 2020 (the "Temporary Relief"), the Company was permitted, subject to the satisfaction of certain conditions, to complete follow-on investments in its existing portfolio companies with certain affiliates that are private funds if such private funds did not previously hold an investment in such existing portfolio company. Without the Temporary Relief, such private funds would not be able to participate in such follow-on investments with the Company unless the private funds had previously acquired securities of the portfolio company in a co-investment transaction with the Company. Although the Temporary Relief expired on December 31, 2020, the SEC’s Division of Investment Management had indicated that until March 31, 2022, it would not recommend enforcement action, to the extent that any BDC with an existing co-investment order continued to engage in certain transactions described in the Temporary Relief, pursuant to the same terms and conditions described therein. The Temporary Relief is no longer effective; however, on August 30, 2022, New Mountain Finance Corporation, an affiliate of the Company and the Investment Adviser, and certain other affiliated applicants, received an Order from the SEC that amended its existing Exemptive Order to permit the Company to complete follow-on investments in its existing portfolio companies with certain affiliates that are private funds if such private funds do not hold an investment in such existing portfolio company, subject to certain conditions.

The revolving period of the Wells Credit Facility ended on July 15, 2023 (the "Revolving Period End Date"). Under the Wells Credit Facility, GIII SPV was permitted to borrow up to 25.0%, 45.0%, 55.0%, 70.0% or 75.0% of the purchase price of pledged assets, subject to approval by Wells Fargo. The Wells Credit Facility was non-recourse to the Company and was collateralized by all of the investments of GIII SPV on an investment by investment basis. All fees associated with the origination, amending or upsizing of the Wells Credit Facility were capitalized on the Company's Consolidated Statements of Assets, Liabilities and Members' Capital and charged against income as other financing expenses over the life of the Wells Credit Facility. Since the amendment on March 11, 2022, the Wells Credit Facility bore interest at a rate of Daily Simple SOFR plus 1.80% per annum for Broadly Syndicated Loans (as defined in the Loan and Security Agreement) and Daily Simple SOFR plus 2.30% per annum for all other investments. The Wells Credit Facility also charged a non-usage fee, based on the unused facility amount multiplied by the Non-Usage Fee Rate (as defined in the Loan and Security Agreement). The following table summarizes the interest expense, non-usage fee and amortization of financing costs incurred on the Wells Credit Facility for the three and nine months ended September 30, 2023: Three Months Ended Nine Months Ended September 30, 2023 September 30, 2023 Interest expense $ 14,836 $ 39,316 Non-usage fee $ 19 $ 277 Amortization of financing costs $ 356 $ 1,060 Weighted average interest rate 7.5 % 7.2 % Effective interest rate 7.8 % 7.5 % Average debt outstanding $ 772,433 $ 721,621 On November 28, 2023, the Company repaid all amounts outstanding under the Wells Credit Facility, including outstanding borrowings and accrued interest, and terminated the Wells Credit Facility. Unsecured Notes —On August 4, 2021, the Company entered into a Master Note Purchase Agreement (the "Note Purchase Agreement") with certain institutional investors (the "Purchasers"). Pursuant to the Note Purchase Agreement, on August 4, 2021, the Company issued to the Purchasers, in a private placement, $125,000 in aggregate principal amount of 3.57% Series 2021A Senior Notes, Tranche A, due July 15, 2025 (the "2021A Tranche A Notes"), and on December 21, 2021, at a second closing, the Company issued $50,000 in aggregate principal amount of 3.62% Series 2021A Senior Notes, Tranche B, due July 15, 2025 (the "2021A Tranche B Notes" and, together with the 2021A Tranche A Notes, the "2021A Unsecured Notes"). On March 10, 2022, the Company entered into a first supplement (the "Supplement") to its Note Purchase Agreement with certain Purchasers. Pursuant to the Supplement, on March 10, 2022, the Company issued to the Purchasers $100,000 in aggregate principal amount of 3.95% Series 2022A Senior Notes due July 15, 2025 (the “2022A Unsecured Notes”). All fees associated with the origination of the 2021A Unsecured Notes and the 2022A Unsecured Notes (together, the "Unsecured Notes") are capitalized on the Company's Consolidated Statements of Assets, Liabilities and Members' Capital and charged against income as other financing expenses over the life of the Unsecured Notes. The 2021A Tranche A Notes and the 2021A Tranche B Notes bear interest at an annual rate of 3.57% and 3.62%, respectively, payable semi-annually on January 15 and July 15 of each year, which commenced on January 15, 2022. The 2022A Unsecured Notes bear interest at an annual rate of 3.95%, payable semi-annual on January 15 and July 15 of each year, which commenced on July 15, 2022. These interest rates are subject to increase in the event that: (i) subject to certain exceptions, the Unsecured Notes or the Company cease to have an investment grade rating or (ii) the Asset Coverage Ratio (as defined in the Note Purchase Agreement) is less than 1.83 to 1.00. The Company is obligated to offer to prepay the Unsecured Notes (i) each time the Company receives an aggregate amount of net proceeds from the repayment, or sale, of loans or investments that constitute Company Level Assets (as defined in the Note Purchase Agreement) and (ii) each time the Company receives an aggregate amount of net proceeds, or if the Company is permitted to receive an aggregate amount of net proceeds, from the distribution of Wells Residual Equity (as defined in the Note Purchase Agreement), in each case that is at least equal to the lesser of (A) $25,000 and (B) 10% of the aggregate principal of Unsecured Notes issued under the Note Purchase Agreement and the Supplement. The Note Purchase Agreement also contains customary terms and conditions for unsecured notes issued in a private placement, including, without limitation, affirmative and negative covenants such as information reporting, maintenance of the Company’s status as a BDC under the 1940 Act and a RIC under Subchapter M of the Code, minimum stockholders’ equity, and prohibitions on certain fundamental changes at the Company or any subsidiary guarantor, as well as customary events of default with customary cure and notice, including, without limitation, nonpayment, misrepresentation in a material respect, breach of covenant, cross-default under other indebtedness of the Company or certain subsidiaries, certain judgments and orders, and certain events of bankruptcy. The Note Purchase Agreement includes certain additional covenants and terms, including, without limitation, a requirement that the Company will not permit the Asset Coverage Ratio to be less than the greater of (x) 1.50 to 1.00 and (y) the minimum asset coverage required to be held by the Company to comply with the 1940 Act. The Unsecured Notes are unsecured obligations and rank senior in right of payment to the Company’s existing and future indebtedness, if any, that is expressly subordinated in right of payment to the Unsecured Notes; equal in right of payment to the Company's existing and future unsecured indebtedness that is not so subordinated; and effectively junior in right of payment to any of the Company's secured indebtedness (including existing unsecured indebtedness that the Company later secures) to the extent of the value of the assets securing such indebtedness; and structurally junior to all existing and future indebtedness (including trade payables) incurred by the Company's subsidiaries and financing vehicles. On May 6, 2024, the Company offered to prepay approximately $50,651 aggregate principal amount, including any accrued but unpaid interest, of the Unsecured Notes pursuant to Section 8.9(a) and (b) of the Note Purchase Agreement.

Recent Accounting Standards Updates	Recent Accounting Standards Updates In March 2020, the Financial Accounting Standards Board issued Accounting Standards Update No. 2020-04, Reference Rate Reform (Topic 848) : Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"). The amendments in ASU 2020-04 provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The standard was effective as of March 12, 2020 through December 31, 2022. Management is currently evaluating the impact of the optional guidance on the Company's consolidated financial statements and disclosures. The Company did not utilize the optional expedients and exceptions provided by ASU 2020-04 during the nine months ended September 30, 2024. In December 2022, the FASB issued ASU No. 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which deferred the sunset day of this guidance to December 31, 2024. The Company is currently evaluating the impact of this guidance on its consolidated financial statements.

Subsequent Events	Subsequent Events Return of Capital Distribution On October 17, 2024, the Company’s board of directors declared a return of capital distribution of $0.20 per unit payable on October 28, 2024 to holders of record as of October 21, 2024. Strategic Transaction with New Mountain Private Credit Fund On October 11, 2024, the Company entered into an Agreement and Plan of Merger (as may be amended from time to time, the “Merger Agreement”), with New Mountain Private Credit Fund, a Maryland statutory trust (“NEWCRED”) and, solely for the limited purposes set forth therein, the Investment Adviser. The Merger Agreement provides that subject to conditions set forth in the Merger Agreement, as of the effective time (the “Effective Time”) the Company will merge with and into NEWCRED, with NEWCRED continuing as the surviving company (the “Merger”). The parties to the Merger Agreement intend the Merger to be treated as a “reorganization” within the meaning of Section 386(a) of the Code. In connection with the Merger, the Company has also agreed to amend the Fourth A&R LLC Agreement to, among other things, extend the Investment Period until August 31, 2025. The Merger In the Merger, each of the Units issued and outstanding immediately prior to the Effective Time (the “Determination Date”) (other than the Units owned by NEWCRED or any of its consolidated subsidiaries (the “Cancelled Units”)) will be converted into the right to receive an amount in cash equal to the Company Per Unit NAV (as defined below) (the “Merger Consideration”). Under the Merger Agreement, on a date which is no earlier than forty-eight (48) hours (excluding Sundays and holidays) prior to the Effective Time, the Company will deliver to NEWCRED a calculation of its estimated NAV, calculated in good faith as of the Determination Date and based on the same assumptions and methodologies, and applying the same categories of adjustments to NAV, historically used by the Company in preparing the calculation of the NAV per Unit (with an accrual for any dividend declared by the Company and not yet paid) (the “Closing NAV”). The consummation of the Merger, which is currently anticipated to occur in December 2024, is subject to certain customary closing conditions, including but not limited to (1) requisite approval of the Company’s unitholders; (2) required regulatory approvals, have been obtained and remain in full force and effect; (3) the determination of the Closing NAV has been completed in accordance with the Merger Agreement; and (4) NEWCRED having sufficient cash and other sources of immediately available funds in an amount sufficient to pay the aggregate Merger Consideration and all fees and expenses expected to be borne by NEWCRED. On October 31, 2024, the Company received the requisite approval from its unitholders to approve the Merger. The Amendment of the Fourth A&R LLC Agreement The Company agreed to amend the Fourth A&R LLC Agreement (the “Fifth A&R LLC Agreement”), subsequent to obtaining the requisite approval of the Company’s unitholders, which occurred on October 31, 2024. Pursuant to the Fourth A&R LLC Agreement, the Company’s Investment Period ended on July 15, 2023, which is the four-year anniversary of the date the Company first accepted capital commitments from unitholders. The Fifth A&R LLC Agreement, among other things, extends the Investment Period until August 31, 2025 for purposes of allowing the Company to retain and use the realized proceeds from the sale or repayment of its investments for making additional investments and paying Company expenses as set forth in Section 4.1(c) of the Fifth A&R LLC Agreement (such extended period, the “Reinvestment Investment Period”) and allows the Company to enter into financing facilities to obtain leverage for purposes of making additional investments with such realized proceeds during the Reinvestment Investment Period. All other references to the Investment Period in the Fifth A&R LLC Agreement remain unchanged.

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2024
Accounting Policies [Abstract]
Basis of accounting	Basis of accounting —The Company's consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States ("GAAP"). The Company is an investment company following accounting and reporting guidance in Accounting Standards Codification Topic 946, Financial Services — Investment Companies ("ASC 946"). The Company consolidates its wholly-owned direct subsidiaries GIII SPV and GIII OEC. The Company's consolidated financial statements reflect all adjustments and reclassifications which, in the opinion of management, are necessary for the fair presentation of the results of operations and financial condition for the period(s) presented. All intercompany transactions have been eliminated. Revenues are recognized when earned and expenses when incurred. The financial results of the Company's portfolio investments are not consolidated in the financial statements. The Company's interim consolidated financial statements are prepared in accordance with GAAP and pursuant to the requirements for reporting on Form 10-Q and Articles 6 and 10 of Regulation S-X. Accordingly, the Company’s interim consolidated financial statements do not include all of the information and notes required by GAAP for annual financial statements. In the opinion of management, all adjustments, consisting solely of normal recurring accruals considered necessary for the fair presentation of financial statements for the interim period, have been included. The current period's results of operations will not necessarily be indicative of results that ultimately may be achieved for the fiscal year ending December 31, 2024.
Investments	Investments —The Company applies fair value accounting in accordance with GAAP. Fair value is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Investments are reflected on the Company's Consolidated Statements of Assets, Liabilities and Members' Capital at fair value, with changes in unrealized gains and losses resulting from changes in fair value reflected in the Company's Consolidated Statements of Operations as "Net change in unrealized appreciation (depreciation) of investments" and realizations on portfolio investments reflected in the Company's Consolidated Statements of Operations as "Net realized gains (losses) on investments". The Company values its assets on a quarterly basis, or more frequently if required under the 1940 Act. In all cases, the Board is ultimately and solely responsible for determining the fair value of the Company's portfolio investments on a quarterly basis in good faith, including investments that are not publicly traded, those whose market prices are not readily available and any other situation where its portfolio investments require a fair value determination. Security transactions are accounted for on a trade date basis. The Company's quarterly valuation procedures are set forth in more detail below: (1) Investments for which market quotations are readily available on an exchange are valued at such market quotations based on the closing price indicated from independent pricing services. (2) Investments for which indicative prices are obtained from various pricing services and/or brokers or dealers are valued through a multi-step valuation process, as described below, to determine whether the quote(s) obtained is representative of fair value in accordance with GAAP. a. Bond quotes are obtained through independent pricing services. Internal reviews are performed by the investment professionals of the Investment Adviser to ensure that the quote obtained is representative of fair value in accordance with GAAP and, if so, the quote is used. If the Investment Adviser is unable to sufficiently validate the quote(s) internally and if the investment's par value or its fair value exceeds the materiality threshold, the investment is valued similarly to those assets with no readily available quotes (see (3) below); and b. For investments other than bonds, the Company looks at the number of quotes readily available and performs the following procedures: i. Investments for which two or more quotes are received from a pricing service are valued using the mean of the mean of the bid and ask of the quotes obtained. The Company will evaluate the reasonableness of the quote, and if the quote is determined to not be representative of fair value, the Company will use one or more of the methodologies outlined below to determine fair value; and ii. Investments for which one quote is received from a pricing service are validated internally. The investment professionals of the Investment Adviser analyze the market quotes obtained using an array of valuation methods (further described below) to validate the fair value. If the Investment Adviser is unable to sufficiently validate the quote internally and if the investment's par value or its fair value exceeds the materiality threshold, the investment is valued similarly to those assets with no readily available quotes (see (3) below). (3) Investments for which quotations are not readily available through exchanges, pricing services, brokers, or dealers are valued through a multi-step valuation process: a. Each portfolio company or investment is initially valued by the investment professionals of the Investment Adviser responsible for the credit monitoring; b. Preliminary valuation conclusions will then be documented and discussed with the Company's senior management; c. If an investment falls into (3) above for four consecutive quarters and if the investment's par value or its fair value exceeds the materiality threshold, then at least once each fiscal year, the valuation for each portfolio investment for which the Company does not have a readily available market quotation will be reviewed by an independent valuation firm engaged by the Board; and d. When deemed appropriate by the Company's management, an independent valuation firm may be engaged to review and value investment(s) of a portfolio company, without any preliminary valuation being performed by the Investment Adviser. The investment professionals of the Investment Adviser will review and validate the value provided. For investments in revolving credit facilities and delayed draw commitments, the cost basis of the funded investments purchased is offset by any costs/netbacks received for any unfunded portion on the total balance committed. The fair value is also adjusted for the price appreciation or depreciation on the unfunded portion. As a result, the purchase of a commitment not completely funded may result in a negative fair value until it is called and funded.
Cash and cash equivalents	Cash and cash equivalents
Revenue recognition	Revenue recognition Sales and paydowns of investments: Realized gains and losses on investments are determined on the specific identification method. Interest and dividend income: Interest income, including amortization of premium and discount using the effective interest method, is recorded on the accrual basis and periodically assessed for collectability. Interest income also includes interest earned from cash on hand. Upon the prepayment of a loan or debt security, any prepayment penalties are recorded as part of interest income. The Company has loans and certain preferred equity investments in its portfolio that contain a payment-in-kind ("PIK") interest or dividend provision. PIK interest and dividends are accrued and recorded as income at the contractual rates, if deemed collectible. The PIK interest and dividends are added to the principal or share balances on the capitalization dates and are generally due at maturity or when redeemed by the issuer. For the three and nine months ended September 30, 2024, the Company recognized PIK interest from investments of $3,498 and $11,326, respectively, and PIK dividends from investments of $2,231 and $7,259, respectively. For the three and nine months ended September 30, 2023, the Company recognized PIK interest from investments of $3,036 and $8,427, respectively, and PIK dividends from investments of $2,482 and $7,206, respectively. Dividend income on preferred securities is recorded as dividend income on an accrual basis to the extent that such amounts are deemed collectible. Non-accrual income: Investments are placed on non-accrual status when principal or interest payments are past due for 30 days or more and when there is reasonable doubt that principal or interest will be collected. Accrued cash and un-capitalized PIK interest or dividends are reversed when an investment is placed on non-accrual status. Previously capitalized PIK interest or dividends are not reversed when an investment is placed on non-accrual status. Interest or dividend payments received on non-accrual investments may be recognized as income or applied to principal depending upon management's judgment of the ultimate collectability. Non-accrual investments are restored to accrual status when past due principal and interest is paid and, in management's judgment, are likely to remain current. As of September 30, 2024 and December 31, 2023, no investments were on non-accrual status. Fee income:
Interest and other financing expenses	Interest and other financing expenses
Organizational expenses	Organizational expenses
Deferred financing costs	Deferred financing costs
Income taxes	Income taxes —The Company has elected to be treated as a RIC for U.S. federal income tax purposes under Subchapter M of the Code and intends to comply with the requirements to qualify and maintain its status as a RIC annually. As a RIC, the Company is not subject to U.S. federal income tax on the portion of taxable income and gains timely distributed to its unitholders. To continue to qualify and be subject to tax treatment as a RIC, the Company is required to meet certain income and asset diversification tests in addition to timely distributing at least 90.0% of its investment company taxable income, as defined by the Code. Since U.S. federal income tax regulations differ from GAAP, distributions in accordance with tax regulations may differ from net investment income and realized gains recognized for financial reporting purposes. Differences between taxable income and the results of operations for financial reporting purposes may be permanent or temporary in nature. Permanent differences are reclassified among capital accounts in the consolidated financial statements to reflect their tax character. Differences in classification may also result from the treatment of short-term gains as ordinary income for U.S. federal income tax purposes. For U.S. federal income tax purposes, distributions paid to unitholders of the Company are reported as ordinary income, return of capital, long term capital gains or a combination thereof. The Company will be subject to a 4.0% nondeductible federal excise tax on certain undistributed income unless the Company distributes, in a timely manner as required by the Code, an amount at least equal to the sum of (1) 98.0% of its respective net ordinary income earned for the calendar year and (2) 98.2% of its respective capital gain net income for the one-year period ending October 31 in the calendar year. Certain consolidated subsidiaries of the Company are subject to U.S. federal and state income taxes. These taxable entities are not consolidated for U.S. federal income tax purposes and may generate income tax liabilities or assets from permanent and temporary differences in the recognition of items for financial reporting and U.S. federal income tax purposes.
Distributions	Distributions —Distributions to the Company's unitholders are recorded on the record date as set by the Board. The Company intends to make timely distributions to its unitholders that will be sufficient to enable the Company to qualify and maintain its status as a RIC. The Company intends to distribute approximately all of its net investment income on a quarterly basis and substantially all of its taxable income on an annual basis, except that the Company may retain certain net capital gains for reinvestment.
Earnings per Unit	Earnings per Unit —The Company's earnings per unit ("EPU") amounts have been computed based on the weighted-average number of Units outstanding for the period. Basic EPU is computed by dividing net increase (decrease) in members' capital resulting from operations by the weighted average number of Units outstanding during the period of computation. Diluted EPU is computed by dividing net increase (decrease) in members' capital resulting from operations by the weighted average number of Units assuming all potential Units had been issued, and its related net impact to members' capital accounted for, and the additional Units were dilutive. Diluted EPU reflects the potential dilution, using the as-if-converted method for convertible debt, which could occur if all potentially dilutive securities were exercised.
Foreign securities	Foreign securities
Use of estimates	Use of estimates —The preparation of the Company's consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the Company's consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Changes in the economic environment, financial markets, and other metrics used in determining these estimates could cause actual results to differ from the estimates used, and the differences could be material.
Fair Value	Fair Value Pursuant to Rule 2a-5 under the 1940 Act, a market quotation is readily available for purposes of Section 2(a)(41) of the 1940 Act with respect to a security only when that "quotation is a quoted price (unadjusted) in active markets for identical investments that the fund can access at the measurement date, provided that a quotation will not be readily available if it is not reliable." Fair value is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosure ("ASC 820") establishes a fair value hierarchy that prioritizes and ranks the inputs to valuation techniques used in measuring investments at fair value. The hierarchy classifies the inputs used in measuring fair value into three levels as follows: Level I —Quoted prices (unadjusted) are available in active markets for identical investments and the Company has the ability to access such quotes as of the reporting date. The type of investments which would generally be included in Level I include active exchange-traded equity securities and exchange-traded derivatives. As required by ASC 820, the Company, to the extent that it holds such investments, does not adjust the quoted price for these investments, even in situations where the Company holds a large position and a sale could reasonably impact the quoted price. Level II —Pricing inputs are observable for the investments, either directly or indirectly, as of the reporting date, but are not the same as those used in Level I. Level II inputs include the following: • Quoted prices for similar assets or liabilities in active markets; • Quoted prices for identical or similar assets or liabilities in non-active markets (examples include corporate and municipal bonds, which trade infrequently); • Pricing models whose inputs are observable for substantially the full term of the asset or liability (examples include most over-the-counter derivatives, including foreign exchange forward contracts); and • Pricing models whose inputs are derived principally from or corroborated by observable market data through correlation or other means for substantially the full term of the asset or liability. Level III —Pricing inputs are unobservable for the investment and include situations where there is little, if any, market activity for the investment. The inputs used to measure fair value may fall into different levels. In all instances when the inputs fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level of input that is significant to the fair value measurement in its entirety. As such, a Level III fair value measurement may include inputs that are both observable and unobservable. Gains and losses for such assets categorized within the Level III table below may include changes in fair value that are attributable to both observable inputs and unobservable inputs. The inputs into the determination of fair value require significant judgment or estimation by management and consideration of factors specific to each investment. A review of the fair value hierarchy classifications is conducted on a quarterly basis. Changes in the observability of valuation inputs may result in the transfer of certain investments within the fair value hierarchy from period to period.
Recent Accounting Standards Updates	Recent Accounting Standards Updates In March 2020, the Financial Accounting Standards Board issued Accounting Standards Update No. 2020-04, Reference Rate Reform (Topic 848) : Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"). The amendments in ASU 2020-04 provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The standard was effective as of March 12, 2020 through December 31, 2022. Management is currently evaluating the impact of the optional guidance on the Company's consolidated financial statements and disclosures. The Company did not utilize the optional expedients and exceptions provided by ASU 2020-04 during the nine months ended September 30, 2024. In December 2022, the FASB issued ASU No. 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which deferred the sunset day of this guidance to December 31, 2024. The Company is currently evaluating the impact of this guidance on its consolidated financial statements.
