Investment Income – Payment-in-Kind Net Realized gains or losses and Net Change in Unrealized Appreciation (Depreciation) on Investments – Investments, At Fair Value Fair value is the price 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. Where available, fair value is based on observable market prices or parameters, or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instruments’ complexity for disclosure purposes. Assets and liabilities recorded at fair value in the Consolidated Statements of Assets and Liabilities are categorized based upon the level of judgment associated with the inputs used to measure their value. Hierarchical levels, as defined under GAAP, are directly related to the amount of subjectivity associated with the inputs to fair valuations of these assets and liabilities, are as follows: Level 1 — Quoted prices are available in active markets for identical financial instruments as of the reporting date. The Company does not adjust the quoted price for these financial instruments, even in situations where the Company holds a large position and the sale of such position would likely deviate from the quoted price. Level 2 — Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date, and fair value is determined through the use of models or other valuation methodologies. These financial instruments exhibit higher levels of liquid market observability as compared to Level 3 financial instruments. Level 3 — Pricing inputs are unobservable for the financial instrument and includes situations where there is little observable market activity for the financial instrument. The inputs into the determination of fair value may require significant management judgment or estimation. Financial instruments that are included in this category generally include investments where the fair value is based on observable inputs as well as unobservable inputs. A significant decrease in the volume and level of activity for the asset or liability is an indication that transactions or quoted prices may not be representative of fair value because in such market conditions there may be increased instances of transactions that are not orderly. In those circumstances, further analysis of transactions or quoted prices is needed, and an adjustment to the transactions or quoted prices may be necessary to estimate fair value. There is no single standard for determining fair values of assets that do not have a readily available market price and, in many cases, such fair values may be best expressed as a range of fair values from which a single estimate may be derived in good faith. As a result, determining fair value requires that judgment be applied to the specific facts and circumstances of each acquisition while employing a valuation process that is consistently followed. Determinations of fair value involve subjective judgments and estimates. When making fair value determinations for Infrastructure Assets that do not have readily available market prices, we will consider industry-accepted valuation methodologies, primarily consisting of an income approach and market approach. The income approach derives fair value based on the present value of cash flows that a business or security is expected to generate in the future. The market approach relies upon valuations for comparable public companies, transactions or assets and includes making judgments about which companies, transactions or assets are comparable. A blend of approaches may be relied upon in arriving at an estimate of fair value, though there may be instances where it is more appropriate to utilize one approach. It is common to use only the income approach for Infrastructure Assets. We also consider a range of additional factors that we deem relevant, including a potential sale of the Infrastructure Assets, macro and local market conditions, industry information and the relevant Infrastructure Asset’s historical and projected financial data. Infrastructure Assets will generally be valued at the relevant transaction price initially; however, to the extent the Operating Manager does not believe an Infrastructure Asset’s transaction price reflects the current market value, the Operating Manager will adjust such valuation. When making fair value determinations for Infrastructure Assets, the Operating Manager will update the prior month-end When making fair value determinations for assets that do not have a reliable, readily available market price, which the Company expects to be the case for a significant number of its Infrastructure Assets, the Operating Manager may engage one or more independent valuation firms to provide positive assurance regarding the reasonableness of such valuations as of the relevant measurement date. Because assets are valued as of a specified valuation date, events occurring subsequent to that date will not be reflected in the Company’s valuations. However, if information indicating a condition that existed at the valuation date becomes available subsequent to the valuation date and before financial information is publicly released, it will be evaluated to determine whether it would have a material impact requiring adjustment of the final valuation. At least annually, the Board, including our independent directors, will review the appropriateness of our valuation guidelines Income Taxes Series II operates so that it will qualify to be treated as a partnership for U.S. federal income tax purposes under the Internal Revenue Code and not a publicly traded partnership treated as a corporation. As such, it will not be subject to any U.S. federal and state income taxes. In any year, it is possible that Series II will not meet the qualifying income exception, which would result in Series II being treated as a publicly traded partnership taxed as a corporation, rather than a partnership. If Series II does not meet the qualifying income exception, the holders of interests in Series II would then be treated as shareholders in a corporation, and Series II would become taxable as a corporation for U.S. federal income tax purposes. Series II would be required to pay income tax at corporate rates on its net taxable income. In addition, Series II holds interests in Infrastructure Assets, through subsidiaries that are treated as corporations for U.S. and non-U.S. Deferred taxes are provided for the effects of potential future tax liabilities in future years resulting from differences between the tax basis of an asset and liability and its reported valuation in the accompanying consolidated financial statements. Income taxes for both Series I and Series II are accounted for under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined on the temporary differences in the basis of assets and liabilities for income tax and financial reporting purposes using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the Consolidated Statements of Operations in the period that includes the enactment date. For a particular tax-paying Both Series I and Series II recognize the tax benefits of uncertain tax positions only where the position is “more likely than not” to be sustained assuming examination by tax authorities. Both Series I and Series II review and evaluate tax positions in their major jurisdictions and determines whether or not there are uncertain tax positions that require financial statement recognition. The reserve for uncertain tax positions is recorded in other accrued expenses and liabilities, as applicable, in the accompanying Consolidated Statements of Assets and Liabilities. Based on this review, both Series I and Series II have determined the major tax jurisdictions to be where both Series I and Series II are organized, where both Series I and Series II hold interests in Infrastructure Assets, and where the Operating Manager is located; however, no reserves for uncertain tax positions were recorded for Series I and Series II for the three and nine months ended September 30, 2024. Both Series I and Series II are not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change materially in the next twelve months. Generally, both Series I and Series II’s returns may be subject to examination for a period of thre Calculation of NAV Recent Accounting Pronouncements – 2022-03, In November 2023, the FASB issued ASU 2023-07, 2023-07”). 2023-07 2023-07 2023-07 In December 2023, the FASB issued ASU 2023-09, There are no other standards, interpretations or amendments to existing standards that are effective that would be expected to have a material impact on the Company.

The number of Shares to be received when distributions are reinvested will be determined by dividing the amount of the distribution, net of any applicable withholding taxes, by the Series’ NAV per share as of the end of the prior month. Shares will be distributed in proportion to the Series and types of Shares held by the Shareholder under the DRIP. There will be no sales load charges on Shares issued to a Shareholder under the DRIP. For the three months ended September 30, 2024, the Company issued Series I A-II Shares Series I E S , 13,044 224 Series II F-I Shares, and Series II E shares for an aggregate purchase price of $ , in each case under the DRIP.

Income Taxes	7. Income Taxes Series I has elected to be treated as a corporation and is subject to current and deferred U.S. federal, state and/or local income taxes. Series II holds interests in Infrastructure Assets, through subsidiaries that are treated as corporations for U.S. and non-U.S. For the three months ended September 30, 2024, the provision for (benefit from) income tax totaled $918, $2,112, and $3,030 for Series I, II and Total, respectively, resulting in an effective tax rate of 24%, 20%, and 21% for Series I, Series II, and Total, respectively. For the nine months ended September 30, 2024, the provision for (benefit from) income taxes totaled $2,068, $5,061, and $7,129 for Series I, II and Total, respectively, resulting in an effective tax rate of approximately 24%, 19%, and 21% for Series I, II and Total, respectively. For Series I, the primary items giving rise to the difference between the 21% federal statutory rate applicable to corporations and the effective tax rate are state and local income taxes (net of federal benefit). For Series II, the primary items giving rise to the difference between the 0% federal statutory rate applicable to partnerships and the effective tax rate are U.S. federal, state, and/or local taxes on the Series II taxable subsidiaries. In evaluating the realizability of deferred tax assets, the Company assesses whether it is more likely than not that some portion, or all, of the deferred tax assets, will be realized. The Company considers, among other things, the generation of future taxable income (including reversals of deferred tax assets) during the periods in which the related temporary differences will become deductible. As of September 30, 2024 and December 31, 2023, the Company has no gross deferred tax assets and therefore, no valuation allowance is necessary.

Investments, At Fair Value	Investments, At Fair Value Fair value is the price 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. Where available, fair value is based on observable market prices or parameters, or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instruments’ complexity for disclosure purposes. Assets and liabilities recorded at fair value in the Consolidated Statements of Assets and Liabilities are categorized based upon the level of judgment associated with the inputs used to measure their value. Hierarchical levels, as defined under GAAP, are directly related to the amount of subjectivity associated with the inputs to fair valuations of these assets and liabilities, are as follows: Level 1 — Quoted prices are available in active markets for identical financial instruments as of the reporting date. The Company does not adjust the quoted price for these financial instruments, even in situations where the Company holds a large position and the sale of such position would likely deviate from the quoted price. Level 2 — Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date, and fair value is determined through the use of models or other valuation methodologies. These financial instruments exhibit higher levels of liquid market observability as compared to Level 3 financial instruments. Level 3 — Pricing inputs are unobservable for the financial instrument and includes situations where there is little observable market activity for the financial instrument. The inputs into the determination of fair value may require significant management judgment or estimation. Financial instruments that are included in this category generally include investments where the fair value is based on observable inputs as well as unobservable inputs. A significant decrease in the volume and level of activity for the asset or liability is an indication that transactions or quoted prices may not be representative of fair value because in such market conditions there may be increased instances of transactions that are not orderly. In those circumstances, further analysis of transactions or quoted prices is needed, and an adjustment to the transactions or quoted prices may be necessary to estimate fair value. There is no single standard for determining fair values of assets that do not have a readily available market price and, in many cases, such fair values may be best expressed as a range of fair values from which a single estimate may be derived in good faith. As a result, determining fair value requires that judgment be applied to the specific facts and circumstances of each acquisition while employing a valuation process that is consistently followed. Determinations of fair value involve subjective judgments and estimates. When making fair value determinations for Infrastructure Assets that do not have readily available market prices, we will consider industry-accepted valuation methodologies, primarily consisting of an income approach and market approach. The income approach derives fair value based on the present value of cash flows that a business or security is expected to generate in the future. The market approach relies upon valuations for comparable public companies, transactions or assets and includes making judgments about which companies, transactions or assets are comparable. A blend of approaches may be relied upon in arriving at an estimate of fair value, though there may be instances where it is more appropriate to utilize one approach. It is common to use only the income approach for Infrastructure Assets. We also consider a range of additional factors that we deem relevant, including a potential sale of the Infrastructure Assets, macro and local market conditions, industry information and the relevant Infrastructure Asset’s historical and projected financial data. Infrastructure Assets will generally be valued at the relevant transaction price initially; however, to the extent the Operating Manager does not believe an Infrastructure Asset’s transaction price reflects the current market value, the Operating Manager will adjust such valuation. When making fair value determinations for Infrastructure Assets, the Operating Manager will update the prior month-end When making fair value determinations for assets that do not have a reliable, readily available market price, which the Company expects to be the case for a significant number of its Infrastructure Assets, the Operating Manager may engage one or more independent valuation firms to provide positive assurance regarding the reasonableness of such valuations as of the relevant measurement date. Because assets are valued as of a specified valuation date, events occurring subsequent to that date will not be reflected in the Company’s valuations. However, if information indicating a condition that existed at the valuation date becomes available subsequent to the valuation date and before financial information is publicly released, it will be evaluated to determine whether it would have a material impact requiring adjustment of the final valuation. At least annually, the Board, including our independent directors, will review the appropriateness of our valuation guidelines
Income Taxes	Income Taxes Series II operates so that it will qualify to be treated as a partnership for U.S. federal income tax purposes under the Internal Revenue Code and not a publicly traded partnership treated as a corporation. As such, it will not be subject to any U.S. federal and state income taxes. In any year, it is possible that Series II will not meet the qualifying income exception, which would result in Series II being treated as a publicly traded partnership taxed as a corporation, rather than a partnership. If Series II does not meet the qualifying income exception, the holders of interests in Series II would then be treated as shareholders in a corporation, and Series II would become taxable as a corporation for U.S. federal income tax purposes. Series II would be required to pay income tax at corporate rates on its net taxable income. In addition, Series II holds interests in Infrastructure Assets, through subsidiaries that are treated as corporations for U.S. and non-U.S. Deferred taxes are provided for the effects of potential future tax liabilities in future years resulting from differences between the tax basis of an asset and liability and its reported valuation in the accompanying consolidated financial statements. Income taxes for both Series I and Series II are accounted for under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined on the temporary differences in the basis of assets and liabilities for income tax and financial reporting purposes using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the Consolidated Statements of Operations in the period that includes the enactment date. For a particular tax-paying Both Series I and Series II recognize the tax benefits of uncertain tax positions only where the position is “more likely than not” to be sustained assuming examination by tax authorities. Both Series I and Series II review and evaluate tax positions in their major jurisdictions and determines whether or not there are uncertain tax positions that require financial statement recognition. The reserve for uncertain tax positions is recorded in other accrued expenses and liabilities, as applicable, in the accompanying Consolidated Statements of Assets and Liabilities. Based on this review, both Series I and Series II have determined the major tax jurisdictions to be where both Series I and Series II are organized, where both Series I and Series II hold interests in Infrastructure Assets, and where the Operating Manager is located; however, no reserves for uncertain tax positions were recorded for Series I and Series II for the three and nine months ended September 30, 2024.

(3) The amount shown at this caption is the balancing amount derived from the other figures in the table. The amount shown at this caption for a share outstanding throughout the period may not agree with the change in the aggregate gains and losses in investments for the period because of the timing of sales of the Company’s shares in relation to fluctuating market value for the portfolio. (4) Actual results may not be indicative of future results. Additionally, an individual shareholder’s ratio may vary from the ratios presented for a share class as a whole. (5) The ratios were derived using the weighted average net assets during the applicable period. (6) For the applicable period, interest income and operating expenses are annualized except for non-recurring (7) 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 all distributions are reinvested in accordance with our distribution reinvestment plan. Amounts are not annualized and are not representative of total return as calculated for purposes of the Performance Fees as described in “Note 4. Related Party Considerations.” The Company, Series I and Series IIs’ 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, Series I and Series II’s shares.
