| Summary of Significant Accounting Policies |
Basis of Presentation The accompanying financial statements of BXINFRA U.S. have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). BXINFRA U.S. is considered an investment company under GAAP and follows the accounting and reporting guidance applicable to investment companies in the Financial Accounting Standards Board Accounting Standards Codification (“ASC”) Topic 946 , Financial Services—Investment Companies ”). Management believes it has made all necessary adjustments (consisting of only normal recurring items) so that the financial statements are presented fairly. Use of Estimates The preparation of 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 financial statements. Management believes that estimates made in preparing its financial statements are reasonable. Such estimates include those used in the valuation of the investment in the Aggregator, including the valuation of the Aggregator’s investments and financial instruments and the measurement of deferred tax balances (including valuation allowances if any), at the Aggregator. Actual results may ultimately differ from those estimates. Principles of Consolidation In accordance with ASC 946 , BXINFRA U.S. generally does not consolidate investments unless BXINFRA U.S. has a controlling financial interest in an investment company or operating company whose business consists of providing services to BXINFRA U.S. A controlling financial interest is defined as (a) the power to direct the activities of the investment company that most significantly impact the entity’s economic performance and (b) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the investment company. BXINFRA U.S. determines whether it has a controlling financial interest in an investment company at such company’s inception and continuously reconsiders that conclusion. In instances where BXINFRA U.S. wholly owns another investment company, BXINFRA U.S. believes this would constitute a controlling interest and consolidation would be appropriate. For non-wholly owned interests in investment companies, BXINFRA U.S. assesses the nature of the investment structure and considers its interests in and governance rights over the investment company to determine whether BXINFRA U.S. holds a controlling financial interest. Performance of that analysis requires the exercise of judgment. BXINFRA U.S. does not have a controlling financial interest in and, as a result, does not consolidate the Aggregator, nor any other reporting entities within BXINFRA, because (a) the General Partner is not acting solely on behalf of BXINFRA U.S. as it carries out its duties and (b) BXINFRA U.S. does not absorb essentially all of the Aggregator’s variability. At each reporting date, BXINFRA U.S. assesses whether it has a controlling financial interest in the Aggregator or any other reporting entities within BXINFRA, and any associated consolidation implications. Valuation of Investments at Fair Value BXINFRA U.S. has indirect exposure to gains and losses on underlying investments because it invests in the Aggregator, which holds such underlying investments. Valuations of investments held by the Aggregator are disclosed in the notes to the Aggregator’s consolidated financial statements. For information regarding net realized and change in unrealized gains and losses on such investments held indirectly by BXINFRA U.S., see the Aggregator’s consolidated financial statements included following these financial statements and see Note 3. “Investments and Fair Value Measurement” in the “Notes to Consolidated Financial Statements” of the Aggregator for information regarding the valuation of investments. BXINFRA U.S. measures its investment in the Aggregator at fair value using the net asset value of the Aggregator. The net asset value of the Aggregator is considered a practical expedient that represents fair value as (a) the investment does not have a readily determinable fair value because the Aggregator’s net asset value is not published or the basis for current transactions, (b) the Aggregator is an investment company and (c) the net asset value of the Aggregator is calculated in a manner in which all of its investments are reported at fair value as of the measurement date. Changes in the fair value of BXINFRA U.S.’s investment in the Aggregator are presented within Net Change in Unrealized Gain (Loss) on Investment in the Aggregator in the Statements of Operations. Cash and Cash Equivalents Cash and Cash Equivalents represents cash on hand, cash held in banks and short-term, highly liquid investments with original maturities of three months or less. BXINFRA U.S. may have bank balances in excess of federally insured amounts; however, BXINFRA U.S. deposits its Cash and Cash Equivalents with high credit-quality institutions to minimize credit risk. Income Taxes BXINFRA U.S. is treated as a partnership for U.S. federal income tax purposes and therefore generally is not subject to any U.S. federal and state income taxes. Taxable income is allocated to BXINFRA U.S.’s unitholders. It is possible that BXINFRA U.S. may be considered a publicly traded partnership and not meet the qualifying income exception in certain years. In such a scenario, BXINFRA U.S. would be treated as a publicly traded partnership taxed as a corporation, rather than a partnership. The investors in BXINFRA U.S. would be treated as shareholders in a corporation, and BXINFRA U.S. itself would become taxable as a corporation for U.S. federal, state and/or local income tax purposes. BXINFRA U.S. would be required to pay income tax at corporate rates on its net taxable income. Deferred Taxes GAAP requires the asset and liability method of accounting for income taxes. Under this method, deferred taxes are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Valuation allowances are established when BXINFRA U.S. determines it is more likely than not that some portion or all of the deferred tax asset will not be realized. BXINFRA U.S. assesses all available positive and negative evidence, including the amount and character of future taxable income. Uncertain Tax Positions BXINFRA U.S. recognizes uncertain tax positions when it is more likely than not that the position will be sustained by the taxing authorities, based on the technical merits of the positions. The tax positions that meet the more-likely-than-not threshold are recognized based on the largest benefit that has a greater than 50 % likelihood of being realized upon ultimate settlement. BXINFRA U.S. reevaluates its tax positions each period in which new information becomes available. BXINFRA U.S.’s policy is to recognize tax-related interest and penalties, if applicable, as a component of the provision for income taxes on the Statements of Operations. Distributions BXINFRA U.S. may declare quarterly distributions to its unitholders. Distributions to unitholders are recognized on the record date of the distribution. All distributions will be declared at the discretion of the General Partner considering factors such as earnings, cash flow, capital needs, taxes and general financial condition, and other such factors as the General Partner may deem relevant from time to time. Although the gross distribution per Unit is equivalent for each class, or series of a class, of Units, the net distribution for each class, or series of a class, of Units may be reduced for any class- or series-specific fees and expenses, if any. BXINFRA U.S. has adopted a distribution reinvestment plan (“DRIP”) pursuant to which unitholders will have their cash distributions automatically reinvested in additional Units of BXINFRA U.S.’s same class of Units to which the distribution relates unless they elect to receive their distributions in cash. Distributions that are reinvested are recognized in net assets on the first calendar day following the record date of a distribution. Affiliates The General Partner, Investment Manager, Dealer Manager (as defined in Note 6. “Related Party Transactions”), the Feeder, Parallel Funds, the Aggregator, BXINFRA Lux and other vehicles sponsored, advised and/or managed by Blackstone or its affiliates are affiliates of BXINFRA U.S. Segment Reporting BXINFRA U.S. operates through a single reportable segment. The chief operating decision makers (the “CODM”) is a group consisting of the BXINFRA U.S.’s Chief Executive Officer and Chief Financial Officer. The CODM assesses the performance of, allocates resources to and makes operating decisions for BXINFRA U.S. primarily based on BXINFRA U.S.’s Net Increase in Net Assets Resulting from Operations. Reportable segment assets are reflected on the accompanying Statements of Assets and Liabilities as Total Assets and reportable segment significant expenses reviewed by the CODM are listed on the accompanying Statements of Operations. |

Basis of Presentation The accompanying consolidated financial statements of the Aggregator have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The Aggregator is considered an investment company under GAAP and follows the accounting and reporting guidance applicable to investment companies in the Financial Accounting Standards Board Accounting Standards Codification (“ASC”) Topic 946, Financial Services—Investment Companies Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of the fair value of investments and financial instruments at the date of the consolidated financial statements. Management believes that estimates made in preparing its financial statements are reasonable. Assumptions and estimates regarding the valuation of investments involve a higher degree of judgment and complexity and these assumptions and estimates may be significant to the consolidated financial statements. Actual results may ultimately differ from those estimates. Principles of Consolidation In accordance with ASC 946, the Aggregator generally does not consolidate its investment in a company unless the Aggregator has a controlling financial interest in (a) an investment company or (b) an operating company whose business consists of providing services to the Aggregator. Accordingly, the Aggregator consolidates wholly owned investment company subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Fair Value of Investments and Financial Instruments ASC Topic 820, Fair Value Measurement Investments measured and reported at fair value are classified and disclosed in one of the following categories:
In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Investment Manager’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the investment. Investments at Fair Value and Investments in Affiliated or Unaffiliated Investee Funds Investments at Fair Value The Aggregator records public and private investments at trade date and closing date, respectively, and values its investments at fair value in accordance with ASC 820. 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. In the absence of observable market prices, the Aggregator’s investments are valued using valuation methodologies applied on a consistent basis as described below. Additional information regarding these investments is provided in Note 3. “Investments and Fair Value Measurement.” The Aggregator’s determination of fair value is based on the best information available in the circumstances and incorporates the Aggregator’s own assumptions, including assumptions that the Aggregator believes market participants would use in valuing the investments, and involves a significant degree of judgment, taking into consideration a combination of internal and external factors, including appropriate risk adjustments for non-performance and liquidity. The values estimated by the Aggregator may differ significantly from values that would have been used had a readily available market for the investments existed and the differences could be material to the consolidated financial statements. Under the income approach, which is generally the Aggregator’s primary valuation approach, fair value is determined by converting future amounts, such as cash flows or earnings, discounted to a single present amount using current market expectations about those future amounts. In determining fair value under this approach, the Aggregator makes assumptions over a projection period regarding unobservable inputs such as revenues, operating income, capital expenditures, income taxes, working capital needs and the terminal value and exit multiple of the investee company, among other things. The Aggregator discounts those projected cash flows by deriving a discount rate based on a capital structure similar to that of a market participant using observable inputs such as the rate of return available in the market on an investment free of default risk, an equity risk premium to reflect the additional risk of a market portfolio of equity instruments over risk-free instruments, beta as a measure of risk based on share price correlation to the market, and equity and debt-to-capital Under the market approach, which is generally the Aggregator’s secondary valuation approach, fair value may be determined by reference to a recent transaction involving the investment or by reference to observable valuation measures for companies or assets that are determined by the Aggregator to be comparable, such as multiplying a key performance metric of the investee company, such as earnings before interest and taxes or other performance metric, by a relevant valuation multiple observed in the range of comparable companies or transactions, adjusted by the Aggregator for differences between the investment and the referenced comparables. Observable inputs used in the market approach to derive a valuation multiple may include the public prices for securities issued by, and the relevant performance metrics of, companies deemed comparable to the investee company, and/or transaction prices involving significant equity interests in companies deemed comparable to the investee company. Unobservable inputs used in the market approach may include the key performance metric of the investee company, such as earnings before interest, taxes, depreciation and amortization (“EBITDA”). Investments may also be valued at their acquisition price for a period of time after an acquisition as the best measure of fair value in the absence of any conditions or circumstances that would indicate otherwise. In the event of an announced sale of investments with a definitive agreement in place, investments may also be valued using a discount-to-sale break-up fees. Investments in debt securities that are not listed on an exchange, but for which external pricing sources, such as dealer quotes or independent pricing services may be available, are valued by the Aggregator after considering, among other factors, such external pricing sources, recent trading activity or market transactions of similar securities adjusted for security-specific factors such as relative capital structure priority and interest and yield risks. Derivative instruments are valued based on contractual cash flows and observable inputs generally comprising of yield curves and foreign currency rates. Publicly traded investments in active markets are reported at the market closing price, less a discount, as appropriate, as determined by the Aggregator to reflect restrictions on disposition where such restrictions are an attribute of the investment. Convertible preferred investments may be valued using an option pricing model based on the specific terms of the security, including, but not limited to, the publicly traded share price of the common shares or units in active markets as of the reporting date, preferred-in-kind Investments in Affiliated or Unaffiliated Investee Funds Investments in Blackstone-affiliated investee funds (“Investments in Affiliated Investee Funds”) or unaffiliated investee funds are generally valued using the reported net asset value (“NAV” or “Net Asset Value”) of the investee funds as a practical expedient for fair value. If the Aggregator determines, based on its own due diligence, investment fair value policies and monitoring procedures, that NAV does not represent fair value or if the investee fund is not an investment company, such as a collateralized loan obligation (“CLO”) vehicle, the Aggregator will estimate the fair value of an investment in good faith and in a manner that it reasonably chooses, in accordance with its valuation policies. For certain Investments in Affiliated Investee Funds that are managed by the Investment Manager, investments held directly on such funds’ balance sheets may also be direct investments of BXINFRA. In these circumstances, the Aggregator and the affiliated investee fund shall apply a consistent fair value methodology to value such investments, with the Aggregator applying a methodology as discussed under the Investments at Fair Value section above. Derivative Instruments The Aggregator recognizes derivative instruments as assets or liabilities at fair value in its Consolidated Statements of Assets and Liabilities as Derivative Assets at Fair Value and Derivative Liabilities at Fair Value, respectively. The Aggregator recognizes changes in fair value of derivative instruments in current period earnings. For derivative financial positions that are closed or that mature during a reporting period, the Aggregator recognizes realized gains or losses equal to the difference between the value of the contract at the time it was opened and the value of the contract at the time it is closed. Realized gains and losses are presented net in Net Realized Gain (Loss) on Investments and Derivative Instruments on the Consolidated Statements of Operations. Changes in the value of contracts that remain outstanding as of period end are measured based on the difference between the unrealized balance as of the beginning of the reporting period and the unrealized balance as of the end of the reporting period, net of any reversals of previously recorded unrealized gains or losses once realized. Unrealized gains and losses are presented net in Net Change in Unrealized Gain (Loss) on Derivative Instruments on the Consolidated Statements of Operations. The Aggregator has elected to not offset derivative assets and liabilities in its Consolidated Statements of Assets and Liabilities, including cash, that may be received or paid as part of collateral arrangements, even when an enforceable master netting agreement is in place that provides the Aggregator, in the event of counterparty default, the right to liquidate collateral and the right to offset a counterparty’s rights and obligations. The Aggregator’s other disclosures regarding derivative instruments are discussed in Note 4. “Derivative Instruments.” Repurchase Agreements Securities sold under agreements to repurchase (“repurchase agreements”) represent collateralized financing transactions. Such transactions are recorded as secured borrowings rather than sales as the Aggregator retains effective control of transferred assets through the term of a repurchase agreement. Secured borrowings are presented within Repurchase Agreements in the Consolidated Statements of Assets and Liabilities at their contractual amounts and include accrued interest. The Aggregator may manage credit exposure arising from repurchase agreements by, in appropriate circumstances, entering into master netting agreements and collateral arrangements with counterparties that provide the Aggregator, in the event of a counterparty default, the right to liquidate collateral and the right to offset a counterparty’s rights and obligations. The Aggregator may also pledge its investments to counterparties to collateralize repurchase agreements. Investments pledged that can be repledged, delivered or otherwise used by the counterparty are recorded within Investments at Fair Value – Pledged to Counterparties in the Consolidated Statements of Assets and Liabilities. Investments which are not pledged to counterparties or which are pledged but cannot be repledged are recorded within Investments at Fair Value – Unpledged in the Consolidated Statements of Assets and Liabilities. The Aggregator does not offset assets and liabilities relating to reverse repurchase agreements and repurchase agreements in its Consolidated Statements of Assets and Liabilities. Additional disclosures relating to repurchase agreements are included in Note 5. “Repurchase Agreements.” Cash and Cash Equivalents Cash and Cash Equivalents represents cash on hand, cash held in banks, money market funds, Treasury Bills and short-term, highly liquid investments with original maturities of three months or less. Interest income from Cash and Cash Equivalents is recorded in Interest Income in the Consolidated Statements of Operations. The Aggregator may have bank balances in excess of federally insured amounts; however, the Aggregator deposits its Cash and Cash Equivalents with high credit-quality institutions to minimize credit risk. Performance Participation Allocation, Administration Fee and Management Fee Payables For more information regarding these payables reported on the Consolidated Statements of Assets and Liabilities, see Note 8. “Related Party Transactions.” Foreign Currency In the normal course of business, the Aggregator makes investments in non-U.S. dollar currency investments. Non-U.S. dollar denominated assets and liabilities are translated to U.S. dollars at the prevailing exchange rate at the reporting date and income, expenses, gains and losses are translated at the prevailing exchange rates at the respective transaction dates. Translation adjustments arising from the translation of non-U.S. dollar denominated assets and liabilities are recorded in Net Change in Unrealized Gain (Loss) on Translation of Assets and Liabilities in Foreign Currencies on the Consolidated Statements of Operations. Net Realized and Unrealized Gain (Loss) on Investments The Aggregator recognizes net realized gains (losses) on investments when earned at the time of receipt of proceeds. Without regard to unrealized gains or losses previously recognized, realized gains or losses will be measured as the difference between the net proceeds from the sale, repayment or disposal of an asset and the adjusted cost basis of the asset. Net Change in Unrealized Gain (Loss) on Investments is the change in fair value of its underlying investments. Net change in unrealized gains or losses will reflect the change in investment values during the reporting period, including any reversal of previously recorded unrealized gains or losses when gains or losses are realized. Income Recognition The Aggregator recognizes interest income from investments when earned pursuant to the terms of the respective investment. The Aggregator recognizes dividend income from its investments when declared. In the case of proceeds received from investments, the Aggregator determines the character of such proceeds and records any interest income, dividend income, realized gain or loss, or return of capital accordingly. Organizational and Offering Expenses Prior to the Initial Closing Date, organizational and offering expenses were paid by the Investment Manager. After BXINFRA U.S. and the Feeder first accepted third-party investors and commenced investment operations, costs associated with the organization of BXINFRA were expensed. Costs associated with the offering of BXINFRA U.S. and the Feeder are capitalized as a deferred expense and included as an asset on the Consolidated Statements of Assets and Liabilities and amortized over a twelve-month period from January 2, 2025. Organization and offering expenses are borne by the Aggregator since the expenses benefit all investors that invest through BXINFRA U.S., the Feeder or any Parallel Fund. Organizational expenses are reported in Organizational Expenses and offering expenses are reported in Deferred Offering Costs Amortization on the Consolidated Statements of Operations. Management Fees Offset and Waived The Investment Manager agreed to waive the Management Fee (as defined in Note 8. “Related Party Transactions”) for the first six months following the Initial Closing Date. The waived Management Fees are reported in Management Fees Waived on the Consolidated Statements of Operations. As described in the Investment Management Agreement (as defined in Note 8. “Related Party Transactions”), the Management Fee shall be reduced (but not below zero) by an amount equal to the respective unitholder’s pro-rata share of 100% of the net break-up, topping, commitment, transaction, monitoring, directors’, organization and divestment fees and management and performance fees borne by BXINFRA through secondary market purchases of existing investments in established investment funds, vehicles, accounts, products and/or other similar arrangements sponsored, advised, and/or managed by Blackstone or its affiliates (“Other Blackstone Accounts”), paid to the Investment Manager or its affiliates in connection with BXINFRA’s investments. These fees, when recognized, are presented as Management Fees Waived. Refer to Note 8. “Related Party Transactions” for more information. Expense Support The Investment Manager voluntarily agreed to pay certain expenses on behalf of BXINFRA such that the total expenses borne by BXINFRA (excluding interest expense, organization and offering expenses, servicing fees, the Performance Participation Allocation (as defined in Note 8. “Related Party Transactions”) and taxes) do not exceed a certain threshold. The amount of expenses the Investment Manager has agreed to pay pursuant to this arrangement is reported in Expense Support on the Consolidated Statements of Operations. Refer to Note 8. “Related Party Transactions” for more information. Income Taxes The Aggregator is treated as a partnership for U.S. federal and state income tax purposes and is not directly subject to U.S. federal and state income taxes. It is possible that the Aggregator may be considered a publicly traded partnership and not meet the qualifying income exception in certain years. In such a scenario, the Aggregator would be treated as a publicly traded partnership taxed as a corporation, rather than a partnership. The investors in the Aggregator would be treated as shareholders in a corporation, and the Aggregator itself would become taxable as a corporation for U.S. federal, state and/or local income tax purposes. The Aggregator would be required to pay income tax at corporate rates on its net taxable income. Additionally, the Aggregator owns a controlling interest in several subsidiaries that are treated as corporations for U.S. and non-U.S. tax purposes (“Aggregator Corporations”) which are subject to U.S. federal, state and/or local income taxes. To the extent investments made by the non-U.S. subsidiaries are engaged in a U.S. trade or business, the subsidiaries will generally be subject to a U.S. federal corporate income tax of 21% of its share of taxable income effectively connected with the conduct of a U.S. trade or business and may be subject to additional branch profits tax of 30% of its share of effectively connected earnings and profits, adjusted as provided by law. The subsidiaries may also be subject to state and local taxes. Federal and state income taxes are expected to be withheld at the source of the U.S. trade or business and taxes withheld can be used as a credit against the income tax liability of the subsidiaries.Deferred Taxes GAAP requires the asset and liability method of accounting for income taxes. Under this method, deferred taxes are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Valuation allowances are established where the Aggregator determines it is more likely than not that some portion or all of the deferred tax asset will not be realized. The Aggregator assesses all available positive and negative evidence, including the amount and character of future taxable income. Uncertain Tax Positions The Aggregator recognizes uncertain tax positions when it is more likely than not that the position will be sustained by the taxing authorities, based on the technical merits of the positions. The tax positions that meet the more-likely-than-not threshold are recognized based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The Aggregator reevaluates its tax positions each period in which new information becomes available. The Aggregator’s policy is to recognize tax related interest and penalties, if applicable, as a component of the Provision for Taxes on the Consolidated Statements of Operations. Distributions The Aggregator may declare quarterly distributions on Aggregator Units (as defined in Note 7. “Net Assets”) as authorized by the General Partner. The declaration of distributions by the Aggregator to BXINFRA U.S. and any Parallel Fund generally occur concurrent with BXINFRA U.S. and any Parallel Fund declaring distributions to its unitholders. Distributions to unitholders are recognized on the record date of the distribution. For further detail on the quarterly distributions to be declared by BXINFRA U.S., see Note 5. “Net Assets” in the “Notes to Financial Statements” of BXINFRA U.S. Affiliates The General Partner, Investment Manager, Blackstone Securities Partners L.P. (the “Dealer Manager”), BXINFRA U.S., the Feeder, Parallel Funds, BXINFRA Lux and O ther Blackstone Accounts are affiliates of the Aggregator. |
