Payment-in-Kind (PIK) interest is accrued monthly on PIK fixed income securities in accordance with the contractual terms of those Infrastructure Assets. In the case of proceeds received from investments in a partnership investment vehicle and limited partnerships, the Company determines the character of such proceeds and record any interest income, dividend income, realized gains or returns of capital accordingly. For the period from April 3, 2023 (date of formation) to December 31, 2023, investment income was comprised of interest income from Infrastructure Assets and cash and cash a Net Realized gains or losses and Net Change in Unrealized Appreciation (Depreciation) on Investments – basis 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 — Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2 — Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar instruments in active markets, and inputs other than quoted prices that are observable for the asset or liability. Level 3 — Inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. 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 valuations by incorporating the then current market comparables and discount rate inputs, any material changes to the financial performance of the Infrastructure Assets since the prior valuation date, as well as any cash flow activity related to the Infrastructure Assets during the month. The Operating Manager will value Infrastructure Assets using the valuation methodology it deems most appropriate and consistent with widely recognized valuation methodologies and market conditions. 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. From time to time, the Board, including our independent directors, may adopt changes to the valuation guidelines on occasions in which it has determined or in the future determines that such changes are likely to result in a more accurate reflection of estimated fair value. 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. tax purposes and therefore may be 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 Statement of Operations in the period that includes the enactment date. 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. For a particular tax-paying component of an entity and within a particular tax jurisdiction, deferred tax assets and liabilities are offset and presented as a single amount within prepaid expenses and other assets or other accrued expenses and liabilities, as applicable, in the accompanying Consolidated Statements of Assets and Liabilities. 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 any of Series I and Series II’s Consolidated Statements of Assets and Liabilities for the period from April 3, 2023 (date of formation) to December 31, 2023. 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 from when they are filed under varying statutes of limitations. Calculation of NAV Recent Accounting Pronouncements – In November 2023, the FASB issued ASU 2023-07 “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”). ASU 2023-07 intends to improve reportable segment disclosure requirements, enhance interim disclosure requirements and provide new segment disclosure requirements for entities with a single reportable segment. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and for interim periods with fiscal years beginning after December 15, 2024. ASU 2023-07 is to be adopted retrospectively to all prior periods presented. The Company is currently assessing the impact this guidance will have on its consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes—Improvements to Income Tax Disclosures. The guidance makes amendments to update disclosures on income taxes including rate reconciliation, income taxes paid, and certain amendments on disaggregation by federal, state, and foreign taxes, as relevant. The guidance is mandatorily effective for the Company for annual periods beginning in 2025, but early adoption is permitted. The Company is currently evaluating the impact of the new standard. There are no other standards, interpretations or amendments to existing standards that are effective for the first time for the year beginning January 1, 2023 that would be expected to have a material impact on the Company.

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 — Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2 — Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar instruments in active markets, and inputs other than quoted prices that are observable for the asset or liability. Level 3 — Inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. 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 valuations by incorporating the then current market comparables and discount rate inputs, any material changes to the financial performance of the Infrastructure Assets since the prior valuation date, as well as any cash flow activity related to the Infrastructure Assets during the month. The Operating Manager will value Infrastructure Assets using the valuation methodology it deems most appropriate and consistent with widely recognized valuation methodologies and market conditions. 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. From time to time, the Board, including our independent directors, may adopt changes to the valuation guidelines on occasions in which it has determined or in the future determines that such changes are likely to result in a more accurate reflection of estimated fair value.
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. tax purposes and therefore may be 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 Statement of Operations in the period that includes the enactment date. 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. For a particular tax-paying component of an entity and within a particular tax jurisdiction, deferred tax assets and liabilities are offset and presented as a single amount within prepaid expenses and other assets or other accrued expenses and liabilities, as applicable, in the accompanying Consolidated Statements of Assets and Liabilities. 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 any of Series I and Series II’s Consolidated Statements of Assets and Liabilities for the period from April 3, 2023 (date of formation) to December 31, 2023. 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 from when they are filed under varying statutes of limitations.

Recent Accounting Pronouncements	Recent Accounting Pronouncements – In November 2023, the FASB issued ASU 2023-07 “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”). ASU 2023-07 intends to improve reportable segment disclosure requirements, enhance interim disclosure requirements and provide new segment disclosure requirements for entities with a single reportable segment. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and for interim periods with fiscal years beginning after December 15, 2024. ASU 2023-07 is to be adopted retrospectively to all prior periods presented. The Company is currently assessing the impact this guidance will have on its consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes—Improvements to Income Tax Disclosures. The guidance makes amendments to update disclosures on income taxes including rate reconciliation, income taxes paid, and certain amendments on disaggregation by federal, state, and foreign taxes, as relevant. The guidance is mandatorily effective for the Company for annual periods beginning in 2025, but early adoption is permitted. The Company is currently evaluating the impact of the new standard. There are no other standards, interpretations or amendments to existing standards that are effective for the first time for the year beginning January 1, 2023 that would be expected to have a material impact on the Company.
