Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements (referred to hereafter as the “financial statements”) are presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and are stated in United States (“U.S.”) dollars. The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures in these consolidated financial statements. Actual results could differ from those estimates. The Company’s consolidated financial statements are prepared using the accounting and reporting guidance under Accounting Standards Codification 946, Financial Services—Investment Companies (“ASC 946”). Basis of Consolidation As provided under Regulation S-X and ASC 946, the Company will generally not consolidate its investment in a company other than a wholly owned investment company or controlled operating company whose business consists of providing services to the Company. Accordingly, the Company consolidates in its consolidated financial statements the accounts of certain wholly owned subsidiaries that meet the criteria. All significant intercompany balances and transactions have been eliminated in consolidation. Adoption of new and revised accounting standards The Company has reviewed recently issued accounting pronouncements and concluded that such pronouncements are either not applicable to the Company or no material impact is expected in the consolidated financial statements as a result of future adoption. For a detailed discussion about the Company’s significant accounting policies, see Note 2 to the audited financial statements in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023. During the three months ended March 31, 2024, there were no significant updates to the Company’s significant accounting policies.

The following table presents the quantitative information about Level III fair value measurements of the Company’s Infrastructure Assets as of March 31, 2024 and December 31, 2023: As of March 31, 2024 As of December 31, 2023 Level III Assets Fair Value March 31, 2024 Fair Value December 31, 2023 Valuation Methodology & Inputs Unobservable Input(s) (1) Weighted Average (2) Range Weighted Average (2) Range Impact to Valuation from an Increase in Input (3) Infrastructure Assets $1,021,161 $983,552 Inputs to market comparables, discounted cash flow and transaction price/other Illiquidity Discount 5.1% 5.0% - 10.0% 5.1% 5.0% - 10.0% Decrease Weight Ascribed to Market Comparables 3.8% —% - 25.0% 4.0% —% - 25.0% (4) Weight Ascribed to Discounted Cash Flow 94.5% —% - 100.0% 94.6% —% - 100.0% (5) Weight Ascribed to Transaction Price/Other 1.7% —% - 100.0% 1.4% —% - 100.0% (6) Market Comparables Enterprise Value / Forward EBITDA Multiple 10.6x 10.6x - 10.6x 10.5x 10.5x - 10.5x Increase Discounted Cash Flow Weighted Average Cost of Capital 9.8% 6.9% - 14.9% 9.7% 6.7% - 12.1% Decrease Enterprise Value / LTM EBITDA Exit Multiple 13.8x 7.1x - 20.0x 13.9x 9.5x - 21.0x Increase (1) In determining the inputs, management evaluates a variety of factors including economic conditions, industry and market developments, market valuations of comparable companies, and company-specific developments including exit strategies and realization opportunities. The Manager has determined that market participants would take these inputs into account when valuing the investments. “LTM” means Last Twelve Months. (2) Inputs are weighted based on fair value of the investments included in the range. (3) Unless otherwise noted, this column represents the directional change in the fair value of the Level III investments that would result from an increase to the corresponding unobservable input. A decrease to the unobservable input would have the opposite effect. Significant increases and decreases in these inputs in isolation could result in significantly higher or lower fair value measurements. (4) The directional change from an increase in the weight ascribed to the market comparables approach would increase the fair value of the Level III investments if the market comparables approach results in a higher valuation than the discounted cash flow approach and transaction price approach. The opposite would be true if the market comparables approach results in a lower valuation than the discounted cash flow approach and transaction price approach. (5) The directional change from an increase in the weight ascribed to the discounted cash flow approach would increase the fair value of the Level III investments if the discounted cash flow approach results in a higher valuation than the market comparables approach and transaction price approach. The opposite would be true if the discounted cash flow approach results in a lower valuation than the market comparables approach and transaction price approach. (6) The directional change from an increase in the weight ascribed to the transaction price approach would increase the fair value of the Level III investments if the transaction price approach results in a higher valuation than the market comparables approach and discounted cash flow approach. The opposite would be true if the transaction price approach results in a lower valuation than the market comparables approach and discounted cash flow approach. Valuations involve subjective judgments and may not accurately reflect realizable value. The assumptions above are determined by the Manager and reviewed by the Manager’s independent valuation advisor. A change in these assumptions or factors would impact the calculation of the value of our assets.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Management Agreement On September 25, 2023, the Company entered into an Amended and Restated Management Agreem ent with the Manager (the “Management Agreement”). Pursuant to the Management Agreement, the Manager is responsible for sourcing, evaluating and monitoring the Company’s acquisition opportunities and making recommendations to the Company’s executive committee related to the acquisition, management, financing and disposition of the Company’s assets, in accordance with the Company’s objectives, guidelines, policies and limitations, subject to oversight by the Board. Pursuant to the Management Agreement, the Manager is entitled to receive a management fee (the “Management Fee”) from the Company in an amount equal to (i) 1.25% per annum of the month-end NAV attributable to Class D Shares, Class I Shares and Class S Shares, (ii) 1.00% per annum of the month-end NAV for a 60-month period following June 1, 2023 (the “Initial Offering”) attributable to Class U Shares, Class R-D Shares, Class R-S Shares and Class R Shares (provided, in the case of Class U Shares, Class R-S Shares and Class R Shares, that such Class U Shares, Class R-S Shares and Class R Shares are purchased by an investor as part of an intermediary’s aggregate subscription for at least $100,000 during the 12-month period following the Initial Offering) and 1.25% per annum of the month-end NAV attributable to Class U Shares, Class R-D Shares, Class R-S Shares and Class R Shares thereafter, each before giving effect to any accruals for certain fees and expenses. Such Management Fee is calculated based on the Company’s transactional net asset value, which is used to determine the price at which the Company sells and repurchases its Shares. KKR or its affiliates (and in the case of directors’ fees, KKR executives) are expected to be paid transaction fees and monitoring fees in connection with the acquisition, ownership, control and exit of Infrastructure Assets, and KKR or its affiliates are expected to be entitled to receive “break-up” or similar fees in connection with unconsummated transactions (“Other Fees”). The Management Fee payable in any monthly period is subject to reduction, but not below zero, by an amount equal to any Other Fees allocable to Investor Shares pursuant to the terms of the Management Agreement. The Manager, in its sole discretion, may forgo reimbursement by the Company of certain expenses incurred by the Manager or its affiliates (other than the Company and its subsidiaries) on behalf of the Company in each calendar month to the extent there remains any Other Fees that are not used to offset the Management Fee. Any Other Fees used to offset such expenses will not be applied again to offset future Management Fees. For the three months ended March 31, 2024, the Manager earned $3,767 in gross Management Fees, which were offset by $3,767, resulting in zero net Management Fees. As of March 31, 2024 and December 31, 2023, there were unapplied credits of $3,158 and $6,533, respectively, to be carried forward that relate to Other Fees earned. As of March 31, 2024 and December 31, 2023, the Company does not owe a net Management Fee to the Manager. Pursuant to the Management Agreement, such amounts earned may be offset by the Manager against amounts due to the Company from the Manager. Performance Participation Allocation Under the LLC Agreement, for as long as the Management Agreement has not been terminated, the Class H Members may receive a Performance Participation Allocation from the Company. The Class H Member is an affiliate of KKR. KKR is allocated a “Performance Participation Allocation” equal to 12.5% of the Total Return attributable to Investor Shares subject to the annual Hurdle Amount and a High Water Mark, with a 100% Catch-Up (each as defined in the LLC Agreement). Such allocation will be measured and allocated or paid annually (excluding the initial Reference Period, as defined in the LLC Agreement) and accrued monthly (subject to pro-rating for partial periods). KKR may elect to receive the Performance Participation Allocation in cash and/or Class F Shares. Specifically, promptly following the end of each Reference Period (and at other times as described below), KKR is allocated a Performance Participation Allocation in an amount equal to: • First, if the Total Return for the applicable period exceeds the sum of (i) the Hurdle Amount for that period and (ii) the Loss Carryforward Amount (any such excess, “Excess Profits”), 100% of such Excess Profits until the total amount allocated to KKR equals 12.5% of the sum of (x) the Hurdle Amount for that period and (y) any amount allocated to KKR pursuant to this clause (any such amount, the “Catch-Up”); and • Second, to the extent there are remaining Excess Profits, 12.5% of such remaining Excess Profits. KKR will also be allocated a Performance Participation Allocation with respect to all Investor Shares that are repurchased in connection with repurchases of Shares in an amount calculated as described above with the relevant period being the portion of the “Reference Period” (which is the applicable year beginning on October 1 and ending on September 30 of the next succeeding year, with the initial Reference Period being the period from June 1, 2023 to September 30, 2024) for which such Shares were outstanding, and proceeds for any such Share repurchases will be reduced by the amount of any such Performance Participation Allocation. Such Performance Participation Allocation is calculated based on the Company’s transactional net asset value, which is used to determine the price at which the Company sells and repurchases its Shares. If the Performance Participation Allocation is paid in Class F Shares, such Shares may be repurchased at KKR’s request and will be subject to the repurchase limitations of our share repurchase plan. A Performance Participation Allocation accrual of $12,412 and $8,335 was recorded as of March 31, 2024 and December 31, 2023 in the Consolidated Statements of Assets and Liabilities. The Consolidated Statements of Operations reflect a $4,077 Performance Participation Allocation for the three months ended March 31, 2024. Dealer-Manager Agreement On September 25, 2023, the Company entered into an Amended and Restated Dealer-Manager Agreement (as amended from time to time, the “Dealer-Manager Agreement”) with KKR Capital Markets LLC (the “Dealer-Manager”). Pursuant to the Dealer-Manager Agreement, the Dealer-Manager solicits sales of the Company’s Shares authorized for issue in accordance with the Company’s confidential Private Placement Memorandum (the “PPM”) and provides certain administrative and shareholder services to the Company, subject to the terms and conditions set forth in the Dealer-Manager Agreement. The Dealer-Manager receives certain front-end sales charges, Distribution Fees, Servicing Fees and certain other fees as described in the PPM. Distribution Fees and Servicing Fees The Company will pay KKR Capital Markets LLC ongoing distribution and servicing fees (a) of 0.85% of NAV per annum for Class S Shares, Class R-S Shares and Class U Shares only (consisting of a 0.60% distribution fee (the “Distribution Fee”) and a 0.25% shareholder servicing fee (the “Servicing Fee”)), payable monthly in arrears, as they become contractually due and (b) of 0.25% for Class D Shares and Class R-D Shares only (all of which constitutes payment for shareholder services, with no payment for distribution services) in each case as accrued, and payable monthly. Such Distribution Fee and Servicing Fee are calculated based on the Company’s transactional net asset value, which is used to determine the price at which the Company sells and repurchases its Shares. Class I Shares, Class R Shares, Class E Shares, Class F Shares, Class G Shares and Class H Shares do not incur Distribution Fees or Servicing Fees. All or a portion of the Distribution Fee or Servicing Fee may be used to pay for sub-transfer agency, platform, sub-accounting and certain other administrative services. The Dealer-Manager (defined below) generally expects to reallow the Distribution Fee and the Servicing Fee to participating broker dealers or other intermediaries. The Company also pays for certain sub-transfer agency, sub-accounting and administrative services outside of the Distribution Fee and Servicing Fee. Under GAAP, the Company accrues the cost of the Servicing Fees and Distribution Fees, as applicable, for the estimated life of the shares as an offering cost at the time the Company sells Class S Shares, Class U Shares, Class D Shares, Class R-D Shares and Class R-S Shares. As of March 31, 2024 and December 31, 2023, the Company has accrued $66,976 and $51,440, respectively, of Servicing Fees and Distribution Fees payable to the Dealer-Manager (defined below) related to the Class U Shares, Class D Shares, Class R-D Shares and Class R-S Shares sold. Expense Limitation and Reimbursement Agreement On December 16, 2023, the Company entered into a Second Amended and Restated Expense Limitation and Reimbursement Agreement (the “Expense Limitation Agreement”) with the Manager, which amended and restated the Amended and Restated Expense Limitation and Reimbursement Agreement, dated as of May 10, 2023. The Expense Limitation Agreement extends the Limitation Period (as defined in the Expense Limitation Agreement) to December 31, 2024. Pursuant to the Expense Limitation Agreement, the Manager will forgo an amount of its monthly management fee and/or pay, absorb or reimburse certain expenses of the Company, to the extent necessary so that, for any fiscal year, the Company’s annual Specified Expenses (defined below) do not exceed 0.60% of the Company’s net assets as of the end of each calendar month. “Specified Expenses” is defined to include all expenses incurred in the business of the Company, including organizational and offering costs, with the exception of (i) the management fee, (ii) the Performance Participation Allocation, (iii) the Servicing Fee, (iv) the Distribution Fee, (v) asset or entity level expenses, (vi) brokerage costs or other investment-related out-of-pocket expenses, including with respect to unconsummated transactions, (vii) dividend/interest payments (including any dividend payments, interest expenses, commitment fees, or other expenses related to any leverage incurred by the Company), (viii) taxes, (ix) ordinary corporate operating expenses (including costs and expenses related to hiring, retaining, and compensating employees and officers of the Company), (x) certain insurance costs and (xi) extraordinary expenses (as determined in the sole discretion of the Manager). The Expense Limitation Agreement will be in effect through and including December 31, 2024, but may be renewed by the mutual agreement of the Manager and the Company for successive terms. Under the Expense Limitation Agreement, the Company has agreed to carry forward the amount of the foregone management fees and/or expenses paid, absorbed or reimbursed by the Manager for a period not to exceed three years from the end of the month in which the Manager waived or reimbursed such fees or expenses and to reimburse the Manager for such fees or expenses in accordance with the Expense Limitation Agreement. As of March 31, 2024, the Manager agreed to reimburse expenses of $1,923 incurred by the Company for the three months ended March 31, 2024, pursuant to the Expense Limitation Agreement, which amount is subject to recoupment within a three year period. On the Company’s Consolidated Statement of Assets and Liabilities, as of March 31, 2024, the Company has recorded $1,923 as amounts Due from Manager Due to Manager On the Company’s Consolidated Statement of Assets and Liabilities, as of December 31, 2023, the Company has recorded $16,549 as amounts Due from Manager Due to Manager The following table reflects the amounts incurred by the Company and subject to recoupment pursuant to the Expense Limitation Agreement and the expiration for future possible recoupments by the Manager: For the Three Months Ended Amount Last Expiration Date September 30, 2022 $ 3,638 September 30, 2025 December 31, 2022 1,797 December 31, 2025 March 31, 2023 2,963 March 31, 2026 June 30, 2023 1,771 June 30, 2026 September 30, 2023 3,906 September 30, 2026 December 31, 2023 2,474 December 31, 2026 March 31, 2024 1,923 March 31, 2027 Total $ 18,472 As of March 31, 2024 and December 31, 2023, management believes that it is not probable for the Company to be required to reimburse the expenses waived by the Manager.

Shareholders may terminate their participation in the DRIP with prior written notice to us. Under the DRIP, Shareholders’ distributions are reinvested in Shares of the same class owned by the Shareholder for a purchase price equal to the most recently available NAV per Share. Shareholders will not pay a sales load when purchasing Shares under the DRIP; however, Class S Shares, Class D Shares, Class U Shares, Class R-S Shares and Class R-D Shares, including those issued under the DRIP, will be subject to applicable ongoing distribution and/or servicing fees. Share Repurchases The Company offers a share repurchase plan pursuant to which, on a quarterly basis, Shareholders may request that the Company repurchase all or any portion of their Shares. The Company may repurchase fewer Shares than have been requested in any particular quarter to be repurchased under its share repurchase plan, or none at all, in its discretion at any time. In addition, the aggregate net asset value (“NAV”) of total repurchases of Class S Shares, Class D Shares, Class U Shares, Class I Shares, Class R-S Shares, Class R-D Shares, Class R Shares and/or Class F Shares under its share repurchase plan will be limited to no more than 5% of our aggregate NAV per calendar quarter (measured using the average aggregate NAV attributable to Shareholders as of the end of the immediately preceding calendar quarter). On February 5, 2024, the Company received requests for the repurchase of approximately $369 of the Company’s Shares. The following table summarizes the Shares repurchased on February 5, 2024: Class Repurchase Price per Share Number of Shares Repurchased Gross Consideration 5% Early Repurchase Fee Net Consideration Class U Shares $ 26.94 4,060 $ 109 $ 5 $ 104 Class R Shares $ 26.96 9,644 260 13 247 Total 13,704 $ 369 $ 18 $ 351 Repurchase Arrangement for Class E Shares held by KKR Pursuant to the Company’s KKR Share Repurchase Arrangement, effective April 28, 2023 (as amended, the “KKR Share Repurchase Arrangement”), on the last calendar day of each month, the Company offers to repurchase Class E Shares from KKR having an aggregate NAV (the “Monthly Repurchase Amount”) equal to (i) the net proceeds from new subscriptions accepted during such month less (ii) the aggregate repurchase amount (excluding any amount of the aggregate repurchase price paid using Excess Operating Cash Flow (defined below)) of Shares repurchased by the Company during such month pursuant to our share repurchase plan. In addition to the Monthly Repurchase Amount for the applicable month, the Company will offer to repurchase any Monthly Repurchase Amounts from prior months that have not yet been repurchased. The price per Class E Share for repurchases from KKR will be the transaction price in effect for the Class E Shares at the time of repurchase. This repurchase arrangement is not subject to any time limit and will continue until the Company has repurchased all of KKR’s Class E Shares. Other than the Monthly Repurchase Amount limitation, the share repurchase arrangement for KKR is not subject to the repurchase limitations in our share repurchase plan. “Excess Operating Cash Flow” means, for any given quarter, the Company’s net cash provided by operating activities, if any, less any amounts of such cash used, or designated for use, to pay distributions to Shareholders. Notwithstanding the foregoing, no repurchase offer will be made to KKR during any month in which (1) the 5% quarterly repurchase limitation of its share repurchase plan has been decreased or (2) the full amount of all Shares requested to be repurchased under our share repurchase plan is not repurchased. Additionally, the Company may elect not to offer to repurchase shares from KKR, or may offer to purchase less than the Monthly Repurchase Amount, if, in the Company’s judgment, the Company determines that offering to repurchase the full Monthly Repurchase Amount would place an undue burden on the Company’s liquidity, adversely affect its operations or risk having an adverse impact on the Company as a whole. Further, the Company’s Board may modify, suspend or terminate this share repurchase arrangement if it deems such action to be in the Company’s best interests and the best interests of its Shareholders. KKR will not request that its Class E Shares be repurchased under our share repurchase plan. For the three months ended March 31, 2024, pursuant to the KKR Share Repurchase Arrangement, the Company did not repurchase any Class E Shares of the Company from KKR. Distributions Each class of the Company’s shares receives the same gross distribution per share, when distributions are declared on such class. The net distribution varies for each class based on the estimated applicable shareholder servicing fees and distribution fees, which is deducted from the quarterly distribution per share and paid directly to the Dealer-Manager on a quarterly basis in arrears, as they become contractually due. The following table details aggregate distributions per share declared for each applicable class of the Company’s shares: For the Three Months Ended March 31, 2024 Class I Shares Class U Shares Class R-D Shares Class R Shares Class D Shares Class R-S Shares Class E Shares Class F Shares Aggregate gross distributions declared per share $ 0.2800 $ 0.2800 $ 0.2800 $ 0.2800 $ 0.2800 $ 0.2800 $ 0.2800 $ 0.2800 Shareholder servicing fees and distribution fees $ — $ 0.0579 $ 0.0170 $ — $ 0.0170 $ 0.0580 $ — $ — Net distributions declared per share $ 0.2800 $ 0.2221 $ 0.2630 $ 0.2800 $ 0.2630 $ 0.2220 $ 0.2800 $ 0.2800 The distributions for each class of shares were payable to holders of record at the close of business on March 31, 2024, with payments on April 24, 2024. The net distributions will be paid in cash or reinvested in shares of the Company for shareholders participating in the Company’s DRIP.

Notwithstanding the foregoing, no repurchase offer will be made to KKR during any month in which (1) the 5% quarterly repurchase limitation of its share repurchase plan has been decreased or (2) the full amount of all Shares requested to be repurchased under our share repurchase plan is not repurchased. Additionally, the Company may elect not to offer to repurchase shares from KKR, or may offer to purchase less than the Monthly Repurchase Amount, if, in the Company’s judgment, the Company determines that offering to repurchase the full Monthly Repurchase Amount would place an undue burden on the Company’s liquidity, adversely affect its operations or risk having an adverse impact on the Company as a whole. Further, the Company’s Board may modify, suspend or terminate this share repurchase arrangement if it deems such action to be in the Company’s best interests and the best interests of its Shareholders. KKR will not request that its Class E Shares be repurchased under our share repurchase plan. For the three months ended March 31, 2024, pursuant to the KKR Share Repurchase Arrangement, the Company did not repurchase any Class E Shares of the Company from KKR. Distributions Each class of the Company’s shares receives the same gross distribution per share, when distributions are declared on such class. The net distribution varies for each class based on the estimated applicable shareholder servicing fees and distribution fees, which is deducted from the quarterly distribution per share and paid directly to the Dealer-Manager on a quarterly basis in arrears, as they become contractually due. The following table details aggregate distributions per share declared for each applicable class of the Company’s shares: For the Three Months Ended March 31, 2024 Class I Shares Class U Shares Class R-D Shares Class R Shares Class D Shares Class R-S Shares Class E Shares Class F Shares Aggregate gross distributions declared per share $ 0.2800 $ 0.2800 $ 0.2800 $ 0.2800 $ 0.2800 $ 0.2800 $ 0.2800 $ 0.2800 Shareholder servicing fees and distribution fees $ — $ 0.0579 $ 0.0170 $ — $ 0.0170 $ 0.0580 $ — $ — Net distributions declared per share $ 0.2800 $ 0.2221 $ 0.2630 $ 0.2800 $ 0.2630 $ 0.2220 $ 0.2800 $ 0.2800 The distributions for each class of shares were payable to holders of record at the close of business on March 31, 2024, with payments on April 24, 2024. The net distributions will be paid in cash or reinvested in shares of the Company for shareholders participating in the Company’s DRIP.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company operates so that it will qualify to be treated as a partnership for U.S. federal income tax purposes under the Internal Revenue Code of 1986, as amended, and not as a publicly traded partnership taxable as a corporation. As such, it will not be subject to any U.S. federal and state income taxes. The Company holds certain equity investments in taxable subsidiaries (the “Taxable Subsidiaries”). The Taxable Subsidiaries permit the Company to hold equity investments in Infrastructure Assets which are “pass through” entities for tax purposes. The Taxable Subsidiaries are not consolidated with the Company for income tax purposes and may generate income tax expense, or benefit, and the related tax assets and liabilities, as a result of the Taxable Subsidiaries’ ownership of certain Infrastructure Assets.

The Manager has determined that market participants would take these inputs into account when valuing the investments. “LTM” means Last Twelve Months. (2) Inputs are weighted based on fair value of the investments included in the range. (3) Unless otherwise noted, this column represents the directional change in the fair value of the Level III investments that would result from an increase to the corresponding unobservable input. A decrease to the unobservable input would have the opposite effect. Significant increases and decreases in these inputs in isolation could result in significantly higher or lower fair value measurements. (4) The directional change from an increase in the weight ascribed to the market comparables approach would increase the fair value of the Level III investments if the market comparables approach results in a higher valuation than the discounted cash flow approach and transaction price approach. The opposite would be true if the market comparables approach results in a lower valuation than the discounted cash flow approach and transaction price approach. (5) The directional change from an increase in the weight ascribed to the discounted cash flow approach would increase the fair value of the Level III investments if the discounted cash flow approach results in a higher valuation than the market comparables approach and transaction price approach. The opposite would be true if the discounted cash flow approach results in a lower valuation than the market comparables approach and transaction price approach. (6) The directional change from an increase in the weight ascribed to the transaction price approach would increase the fair value of the Level III investments if the transaction price approach results in a higher valuation than the market comparables approach and discounted cash flow approach. The opposite would be true if the transaction price approach results in a lower valuation than the market comparables approach and discounted cash flow approach. Valuations involve subjective judgments and may not accurately reflect realizable value. The assumptions above are determined by the Manager and reviewed by the Manager’s independent valuation advisor. A change in these assumptions or factors would impact the calculation of the value of our assets.

Additionally, an individual Shareholder’s ratios may vary from the ratios presented for a share class as a whole. (5) Weighted average net assets during the applicable period are used for this calculation. (6) Ratios presented after accounting for the accrual of the Performance Participation Allocation. (7) Ratios presented after expenses reimbursed by Manager. (8) The Total return is calculated for each share class as the change in the net asset value for such share class during the period plus any distributions per share declared in the period, and assumes any distributions are reinvested in accordance with the Company’s distribution reinvestment plan. Amounts are not annualized and are not representative of total return as calculated for purposes of the Performance Participation Allocation as described in “Note 5. Related Party Transactions.” The Company’s performance changes over time and currently may be different than that shown above. Past performance is no guarantee of future results. Investment performance is presented without regard to sales load that may be incurred by Shareholders in the purchase of the Company’s shares. See “Note 7. Distributions” above, for declarations of distributions for the period from January 1, 2024 to March 31, 2024.
