Other Expenses are estimated for the 12 months ending June 30, 2025. (5) Includes amounts paid under an administration agreement (the “Administration Agreement”) between the Fund and StepStone Private Wealth as administrator (the “Administrator”). Under the Administration Agreement, the Fund pays the Administrator an administration fee (the “Administration Fee”) in an amount up to 0.23% on an annualized basis of the Fund’s net assets. From the proceeds of the Administration Fee, the Administrator pays UMB Fund Services, Inc. (the “Sub-Administrator”) sub-administration “Sub-Administration Sub-Administration sub-administration Sub-Administrator. Sub-Administration (6) The Adviser has entered into an Expense Limitation and Reimbursement Agreement with the Fund for the Limitation Period. The Adviser may extend the Limitation Period for a period of one year on an annual basis. The Expense Limitation and Reimbursement Agreement limits the amount of the Fund’s aggregate ordinary operating expenses, excluding certain Specified Expenses listed below, borne by the Fund during the Limitation Period to an amount not to exceed 1.00% for Class T, S, D and I Shares, on an annualized basis, of the Fund’s daily net assets or the Expense Cap. “Specified Expenses” that are not covered by the Expense Limitation and Reimbursement Agreement include: (i) the Management Fee; (ii) all fees and expenses of Private Market Assets and other investments in which the Fund invests (including the underlying fees of the Private Market Assets and other investments (the Acquired Fund Fees and Expenses)); (iii) transactional costs, including legal costs and brokerage commissions, associated with the acquisition and disposition of Private Market Assets and other investments; (iv) interest payments incurred on borrowing by the Fund; (v) fees and expenses incurred in connection with a credit facility, if any, obtained by the Fund; (vi) distribution and/or shareholder servicing fees, as applicable; (vii) taxes; and (viii) extraordinary expenses resulting from events and transactions that are distinguished by their unusual nature and by the infrequency of their occurrence, including, without limitation, costs incurred in connection with any claim, litigation, arbitration, mediation, government investigation or similar proceeding, indemnification expenses, and expenses in connection with holding and/or soliciting proxies for all annual and other meetings of Shareholders. See “Fund Expenses” for additional information. If the Fund’s aggregate ordinary operating expenses, exclusive of the Specified Expenses, in respect of any Class of Shares for any day exceeding the Expense Cap applicable to that Class of Shares, the Adviser will waive its Management Fee and/or reimburse the Fund for expenses to the extent necessary to eliminate such excess. The Adviser may also directly pay expenses on behalf of the Fund and waive reimbursement under the Expense Limitation and Reimbursement Agreement. To the extent that the Adviser waives its Management Fee, reimburses expenses to the Fund or pays expenses directly on behalf of the Fund, it is permitted to recoup from the Fund any such amounts for a period not to exceed three years from the month in which such fees and expenses were waived, reimbursed, or paid, even if such recoupment occurs after the termination of the Limitation Period. However, the Adviser may only recoup the waived fees, reimbursed expenses or directly paid expenses in respect of the applicable Class of Shares if (i) the aggregate ordinary operating expenses have fallen to a level below the relevant Expense Cap and (ii) the recouped amount does not raise the level of aggregate ordinary operating expenses plus waived fees, reimbursed expenses or directly paid expenses in respect of a Class of Shares in the month of recoupment to a level that exceeds any Expense Cap applicable at that time. (7) Annual Net Expenses include expenses limited by the Fund’s Expense Limitation and Reimbursement Agreement.

General Description of Registrant [Abstract]
Investment Objectives and Practices [Text Block]		INVESTMENT PROGRAM Investment Objectives The Fund’s investment objectives are to seek current income and long-term capital appreciation by offering investors access to a global investment portfolio of private infrastructure assets. Investment Strategy The principal elements of the Fund’s investment strategy include: (i) allocating the assets of the Fund largely among Infrastructure Assets via Secondary Investments, Co-Investments, non-fundamental Asset Allocation value-add value-add • Core: Considered the most stable form of infrastructure equity investing, as these assets tend to be the most essential to society or otherwise largely risk mitigated through a higher degree of cash flow predictability. Returns are derived primarily from income, with limited upside through capital gains, and assets are commonly held for the longer term (more than seven years). Revenues and cash flow are generally governed by either rate regulation or long-term contracts with highly creditworthy counterparties, such as governments, municipalities and major industrial companies. • Core Plus: These assets have some similarities with core infrastructure; however, there is generally more variability associated with the cash flows of core plus assets. Income is still typically a component of overall returns, but there is potential for greater capital appreciation. The holding period for core plus assets is typically more than six years. Core plus infrastructure may involve asset expansion or platform growth but the majority of value is typically derived from a relatively mature asset base. Core plus could also reflect a “build to core” strategy, where the assets would have a higher risk-return profile during a development, construction, and early operations stage, but ultimately qualify as a core asset for the long-term hold period. • Value-Add: value-add Commitment Strategy. “J-Curve,” The Fund relies heavily on purchases of Secondary Investments where all or a substantial portion of the capital has already been invested and Co-Investments “J-Curve” The commitment strategy aims to keep the Fund substantially invested and to minimize cash drag, where possible, by making commitments based on anticipated future distributions from investments. The commitment strategy will also take other anticipated cash flows into account, such as those relating to new subscriptions, the redemption of Shares by Shareholders and distributions to Shareholders. To forecast portfolio cash flows, the Advisers will utilize a proprietary model that incorporates historical data, actual portfolio observations, insights, and forecasts by the Advisers. Risk Management. • Investing across assets at different parts of fund lifecycles through the use of Secondary Investments, Co-Investments • Managing cash and liquid assets to meet the Fund’s liquidity needs. • Modeling and actively monitoring cash flows to avoid cash drag and maintain maximum appropriate levels of investment and commitment. • Seeking to establish credit lines to provide backup liquidity to be in the position to satisfy liquidity needs, including redemption requests under the share repurchase program, consistent with the limitations and requirements of the 1940 Act. To enhance the Fund’s liquidity, particularly in times of possible net outflows through the redemption of Shares by Shareholders, the Advisers may from time to time determine to sell certain of the Fund’s assets. In implementing the Fund’s liquidity management program, so as to minimize cash drag while providing the necessary liquidity to support the Fund’s private markets investment strategies and potential redemption of Shares, the Advisers may invest a portion of the Fund’s assets in securities and vehicles that are intended to provide an investment return while offering better liquidity than typical private markets investments. The liquid assets may include both fixed income and equities as well as public and private vehicles that derive their investment returns from fixed income and equity securities. The Fund’s strategy involves investing in a range of Infrastructure Assets across multiple sponsors and investment types. The portfolio will consist of Infrastructure Assets that vary across industry sectors and geographies allocated strategically by StepStone. The Fund intends to make direct and indirect investments in equity and debt interests across a variety of Infrastructure Assets such as: • Communication and digital infrastructure ( e.g., • Natural capital (e.g., • Power generation and midstream ( e.g., • Renewables and energy transition investments ( e.g., • Social infrastructure ( e.g., • Transportation and logistics ( e.g., • Utilities ( e.g., The Fund will look to access attractive industry themes and tailwinds by tracking the evolving market and the emerging strategies of a diverse pool of Investment Managers. Outlined below are examples of current sector themes expected to support key investment focus areas of the Fund. Private Infrastructure Themes In select cases, the Fund may allocate a portion of its investments to other private market asset classes, including but not limited to real estate, private equity and private debt. The Fund will also seek to construct a balanced portfolio across mainly developed economies, with a focus on North America and Europe. While maintaining a generally balanced portfolio across these exposures is a focus of the Fund’s investment strategy, the Advisers will also be continuously assessing the relative attractiveness of the risk / return profile of each Fund opportunity and will look to tactically tilt the portfolio in situations where market dynamics make it attractive to do so, while still seeking to avoid over-concentration. Risks associated with investment in geographical locations, emerging markets and sector concentration are further described in the “Types of Investments and Related Risks” The Fund’s investment objectives and strategies are non-fundamental Real Assets Asset Class The real assets asset class includes infrastructure, natural capital and natural resource investments, among other hard asset categories. A common thread across the sub-strategies Infrastructure refers to a broad category of investments typically featuring attractive investment characteristics such as essential services or high barriers to entry, relatively durable demand, regulated returns or long term contracted cash flow and long useful lives, with an expected component of current yield as assets mature and often an insulation of the underlying assets against the effects of inflation. Infrastructure assets may include, among other asset types, communication/digital infrastructure, power generation and midstream, renewables & energy transition investments, social infrastructure, transportation and logistics and utilities. Natural capital is viewed as an attractive complement to the Fund’s other assets, with its focus on sustainable agriculture, sustainable forestry and other sustainable natural assets. Sustainable agriculture consists of investments in farmland and related supply chain assets, along with biological assets ( e.g., 5 While most Infrastructure Assets benefit in some way from defensive characteristics, in the form of essential services, barriers to entry, contracted cash flows or regulated returns, the risk and return profile of infrastructure investments does differ across sectors and strategies, and assets are often grouped into a few key categories, reflecting these differences. Expected Positioning of Select Sectors 6 Real Estate Asset Class Private real estate is a common term for unregistered real estate investments made through privately negotiated transactions. Similar to investments in the infrastructure asset class, real estate investments generally provide investment returns with a mix of current yield and growth across the underlying assets. The ultimate mix will 5 According to MSCI Private Infrastructure Index, global core infrastructure has low or no correlation to global private equity, global public bonds and global equities with correlation coefficients of 0.0, -0.1 6 For illustrative purposes only. Sectors may differ in risk and return from the above. Target gross returns are hypothetical and are neither guarantees nor predictions or projections of future performance. Future performance indications and financial market scenarios are no guarantee of current or future performance. There can be no assurance that such target will be achieved or that the investment will be able to implement its investment strategy, achieve its investment objectives or avoid substantial losses. vary depending on the stage of development of the underlying assets. Real estate investments are typically equity investments in the underlying real estate property, but in some cases, may also involve the debt/mortgages supporting the properties. Private Equity Asset Class Private equity is a common term for investments that are typically made in non-public The private equity market is diverse and can be divided into several different segments, each of which may exhibit distinct characteristics based on combinations of various factors. These include the type and financing stage of the investment, the geographic region in which the investment is made and the vintage year. The Fund may invest in all segments of private equity on a global basis. Private Debt Asset Class Private debt is a common term for loans and similar investments typically made in private companies that are generally negotiated directly with the borrower. Private debt investments may be structured using a range of financial instruments, including but not limited to, first and second lien senior secured loans, unitranche debt, unsecured debt, and structurally subordinated instruments. From time to time these investments might include equity features such as warrants, options, common stock or preferred stock, depending on the strategy of the investor and the financing requirements of the company or asset. The Fund’s private debt investments may be rated below investment grade by rating agencies or would be rated below investment grade if they were rated and are sometimes referred to as “junk.” Below investment grade securities have predominantly speculative characteristics and may carry a greater risk with respect to a borrower’s capacity to pay interest and repay principal. The global capital markets have undergone substantial structural changes since the 2008-2009 global financial crisis. Where once banks were dominant providers of credit, their relative size is in secular decline, thus creating an opportunity for other providers of capital. In addition, a new regulatory regime surrounding bank balance sheets has placed greater emphasis on the private non-bank Why Infrastructure The Advisers believe investors should consider the following factors when considering an investment in the Fund. Essential Services are Resilient to Economic Cycles: 7 Inflation Hedge: non-regulated end-user. 7 According to MSCI Private Infrastructure Index, global core infrastructure has low or no correlation to global private equity, global public bonds and global equities with correlation coefficients of 0.0, -0.1 Diversified End-User Base: end-users High Barriers to Entry: Long-term Cash Flow Predictability: Sustainability Tailwinds: Key Trends in Infrastructure Infrastructure Assets can be broadly described as economic and social necessities that deliver services and products needed to improve society’s quality of life, social well-being, and safety. The U.S. economy, for example, relies on a vast network of transportation, power and communications infrastructure; however, much of the systems currently in place were built decades ago, and economists assert that delays and rising maintenance costs are limiting economic performance. Many are reaching the end of their lifespan and are potentially overstretched. In addition to the threat to human safety, inadequately maintained roads, trains, and waterways substantially limit economic productivity. Similar infrastructure investment opportunities exist in other major economies around the world. Infrastructure is not only an essential part of healthy and productive communities and economies today but is also one of the most important areas of investment for addressing the challenges of tomorrow. Challenges around climate change, communication, healthcare and urbanization may be addressed through major public and private investment in infrastructure. It is estimated that the world needs approximately $94 trillion of infrastructure investment to support population growth, urbanization, and refurbishments through 2040. 8 Digitalization • Mobile Towers • Data Centers 9 on-premise 8 Global Infrastructure Outlook: Infrastructure Investment Needs, June 2018. 9 Worldwide IDC Global Data Sphere Forecast, 2022–2026: Enterprise Organizations Driving Most of the Data Growth, May 2022. • Fiber Optics 10 11 Decarbonization: • Renewable Energy Transition: • Electrification Revolution • Internet of Things (“IoT”) Demographics: medium-sized • Growing Population 12 • Urbanization 13 • Changing Generational Preferences 10 We Are Social: More Than 5 million People Now Use the Internet, 4/27/2022. 11 USAID: Barriers to Investing in Last-Mile Connectivity, May 2020. 12 United Nations: Department of Economic and Social Affairs, 2017. 13 World Economic Forum: Cities and Urbanization, 4/26/2022. Investment Types The Fund makes investments in equity and debt interests in Infrastructure Assets through the various investment types described below. Secondary Investments Secondary Investments typically refer to investments in either individual operating companies, projects or properties and existing private investment funds through the acquisition of an existing interest by one investor from another in a negotiated transaction. In so doing, the buyer will acquire the existing interest and take on any future funding obligations in exchange for future returns and distributions. Secondaries include the growing general partner led secondary market, which has evolved toward strip sales and continuation vehicles with general partners structuring a vehicle that allows for continued participation in the growth of the remaining assets, or a specific asset, beyond a fund’s traditional exit time frame. Secondaries may also include newly established private markets funds that are fully funded at the time of the Fund’s acquisition. Secondary Investments may be acquired at a discount to the Investment Fund’s NAV. As a result, Secondary Investments acquired at a discount may result in unrealized gains at the time the Fund next calculates its daily NAV. Because Secondary Investments are generally made when a Primary Investment is three-to-seven 70-75% “J-Curve” Open-Ended Funds typically refer to investments in evergreen or long duration structures, where the interest of one or multiple investors is acquired by another investor, or an interest is acquired by an investor through the provision of growth capital, in both cases typically at NAV. For the purposes of the Fund strategy, Open-Ended Funds are considered Secondary Investments, given they are, similarly, the acquisition of an interest in what is typically a mature portfolio, and all, or the majority, of capital is deployed at the time of investment, and therefore the impact of the “J-Curve” The market for purchasing Investment Funds on the secondary market may be very limited and competitive, and the strategies and Investment Funds to which the Fund wishes to allocate capital may not be available for secondary investment at any given time. Purchases of Investment Funds on the secondary market may be heavily negotiated and may create additional transaction costs for the Fund. The secondary market continues to evolve and expand. Secondaries may include various structures by which the Fund gains exposure to the private markets including those described above and others that share some of the same characteristics. The Fund may invest in the equity or debt of structured transactions such as collateralized fund obligations or similar investment vehicles (“CFOs”) that own existing funds and co-investments. open-end closed-end Co-Investments Co-Investments Co-Investments co-investors Co-Investment J-Curve Co-Investments Primary Investments Primary Investments, or “primaries,” refer to investments in newly established private market funds that are early in their lifecycle and have typically not yet begun investing. Primary investments are made during an initial fundraising period in the form of capital commitments, which are then called down by the Fund and utilized to finance its investments in portfolio companies during a predefined period. A private markets fund’s NAV will typically exhibit a “J-Curve,” ten-to-twelve eight-to-ten three-to-six-year Primary Investments are generally closed-end two-to-four top-tier Primary Investments includes Seasoned Primaries, which are made later in an Investment Fund’s lifecycle than typical primaries, these investments, like secondaries, may receive earlier distributions, and the investment returns from these investments may exhibit less of a delayed cash flow and return “J-Curve” General Due Diligence StepStone uses a range of resources to identify and source promising Infrastructure Assets. StepStone’s investment approach is based on the extensive diligence conducted by its research professionals while leveraging the capabilities of the entire StepStone organization and its potential access to superior information. StepStone focuses on identifying opportunities at the intersection of high-quality opportunities, Investment Manager expertise and the Firm’s informational advantage. StepStone will assess the relative attractiveness of different strategies, sectors and geographies based on durable investment themes that it believes will outperform over the Fund’s long-term investment horizon. Shorter-term opportunistic allocations will also be utilized to seek to capitalize on near-term market trends. The due diligence process is driven by StepStone’s entire global team, which meets bi-weekly The Fund’s investment due diligence process generally is expected to include these elements: Secondary Investments • Independent financial modeling on an asset-by-asset • Research and analysis of the assets, sectors and strategies related to the Investment Fund, and the effect on underlying portfolio positions. • Assessment of the managerial capability of the Investment Manager and the quality of the Investment Fund, including the Investment Manager’s ability and bandwidth for managing the existing portfolio towards liquidity. • ESG and Operational Due Diligence. Co-Investments • Independent financial modeling as a means of testing and validating the business plan assumptions and projections, exit returns and valuations. • Comparative analysis through review and the assigning of a risk score, considering key quantitative and qualitative risk factors including, but not limited to, regulatory risk, technology risk and market risk. • Industry research (including evaluation of market size, potential growth and competitive dynamics). • Assessment of the Investment Manager’s suitability for the investment and the managerial capability and depth at the underlying asset level. • ESG and Operational Due Diligence. Primary Investments • Evaluation of the Investment Manager’s experience and resources to establish their ability to implement its investment strategy, through team, platform and performance assessments, discussions with third party references (including the Investment Manager community, limited partner community, and portfolio company founders), Investment Manager interviews, and other fund manager meetings. • Evaluation of the proposed investment strategy for appropriateness to the investment environment. • Detailed review of the Investment Managers prior track record, including individual investment partner level attribution, and projection modeling for historical funds. • Assessment of operational support and bandwidth for managing the existing portfolio. • ESG and Operational Due Diligence. • Evaluation of fund terms with a particular focus on alignment of interests between the Investment Manager and limited partners. For each transaction, the assigned investment team gathers and reviews available information on the historical track record and all underlying assets. To facilitate this process, StepStone utilizes the SPI platform, which tracks over 16,000 general partners across 42,000 Investment Funds garnered from the over 4,700 annual Investment Manager meetings the Firm holds per year. This database is populated with information StepStone has gathered from Investment Manager partner meetings, due diligence materials, quarterly reports, annual meetings, marketing materials and other sources. Through these sources, StepStone believes that it has access to significantly more information than most investors and provides a distinctive advantage when evaluating a potential investment. The Advisers also continue to monitor the assets by meeting with Investment Managers, attending annual meetings, serving on portfolio companies’ investment boards, reviewing financial reports and meeting with portfolio companies’ management teams. Based on these interactions, the Advisers will periodically update expectations of return and liquidity of each asset of the Fund. ESG Due Diligence As demonstration of its commitment to responsible investing (“RI”), the Firm became a signatory to the United Nations Principles for Responsible Investment (“UN PRI”) in 2013, adopted a responsible investment policy (“Responsible Investment”) in 2014 and joined the Task Force on Climate-related Financial Disclosures (“TCFD”) in 2019. The Firm’s RI policy is approved by the (“RI Committee”) under delegated authority from the Board of the Firm. It is enforced by the Firm’s Investment Committees (“Investment Committee” or “IC”) and applies to the Firm’s various private markets asset classes and investment strategies. This policy encompasses a comprehensive assessment at both the general partner and asset level of non-financial Process Overview. Responsible Investment Integrated in the Due Diligence Process. i.e., co-investments Portfolio Allocation In allocating the Fund’s capital, the Advisers seek to maximize the risk adjusted returns to the Shareholders. The overall portfolio construction seeks to achieve targeted returns while also being able to provide 5% quarterly liquidity, and also minimizing volatility for investors. Capital is allocated within differing types of infrastructure investments to optimize risk, return, volatility, correlation and liquidity using equity and debt investments with varying levels of duration. Portfolio allocations are achieved through using a combination of Secondary Investments, Co-Investments In allocating the Fund’s capital, the Advisers seeks to use the resources and capabilities they have assembled to build a diversified portfolio of investments that seeks to mitigate the effects of the J-Curve returns to the Shareholders. Portfolio construction is the first level of the risk management process. At a high level, the planning for portfolio construction is intended to consider medium- to long-term secular and macroeconomic risks, and how they are likely to impact the infrastructure market. A fundamental premise of the Fund’s investment strategy is to prioritize a proactive sourcing approach for all forms of Infrastructure Assets, driven by a thoughtful portfolio construction plan. The projected asset allocation targets reflect the current assessment of sub-sectors Co-Investments. Asset Allocation Targets Investment Type Target Range Secondary Investments 40-80% Co-Investments 20-50% Primary Investments 0-10% Asset Class Target Range Infrastructure Assets 90-100% Other Assets 0-10% Geographic Region Target Range North America 40-70% Europe 20-50% Rest of World 5-15% The Fund’s assets are global, although the Fund expects to invest principally in North America-domiciled and European-domiciled investments. Over time, the Fund may have exposure to developing or emerging markets. There can be no assurance that all investment types will be available, will be consistent with the Fund’s investment objectives, will satisfy the Advisers’ pricing and due diligence considerations or will be selected for the Fund. While the Fund actively pursues Co-Investments, The Firm’s Allocation Policy Allocation decisions may arise when there is more demand from the Fund and other clients of the Firm for a particular investment opportunity, such as the capacity in an Investment Fund or a Co-Investment, With respect to Primary Investments, the Firm uses its best efforts to defer the allocation decision to the relevant Investment Manager, mitigating the potential conflict. With regard to secondary purchases of Investment Funds, the Firm typically manages the allocation of the transactions across its clients. Under the Firm’s allocation policy, if clients are similarly situated, considering all relevant facts and circumstances, allocations will be made pro rata based on the deployment pace for each client determined in accordance with the Firm’s standard operational processes and specified in each client’s annual portfolio plan. Allocation of Co-Investments approach on Investment Funds; in certain cases, Co-Investments Importantly, the Firm’s allocation process is managed independently by the Finance team and ratified by the Firm’s Legal and Compliance department. Leverage In the near term, leverage may be used to provide the Fund with temporary liquidity to acquire investments in advance of the Fund’s receipt of proceeds from the realization of other assets or additional sales of Shares. The 1940 Act requires a registered investment company to satisfy an asset coverage requirement of 300% of its indebtedness, including amounts borrowed, measured at the time the investment company incurs the indebtedness (the “Asset Coverage Requirement”). This requirement means that the value of the investment company’s total indebtedness may not exceed one third the value of its total assets (including the indebtedness). The 1940 Act also requires that dividends may not be declared if this Asset Coverage Requirement is breached. The Fund’s borrowings will at all times be subject to the Asset Coverage Requirement. The Fund’s assets may also utilize leverage in their investment activities. Borrowings at the individual investment level are not subject to the Asset Coverage Requirement. Accordingly, the Fund’s portfolio may be exposed to the risk of highly leveraged investment programs of certain assets and the volatility of the value of Shares may be great, especially during times of a “credit crunch” and/or general market turmoil, such as that experienced during late 2008 or the current global pandemic. In general, the use of leverage by the Fund’s assets may increase the volatility of their values and of the value of the Shares. See “Types of Investments and Related Risks — Investment Related Risks — Leverage Utilized by the Fund.”
Risk Factors [Table Text Block]		TYPES OF INVESTMENTS AND RELATED RISKS General The value of the Fund’s total net assets may be expected to fluctuate in response to fluctuations in the value of the Infrastructure Assets in which the Fund invests. Discussed below are the investments generally made by Investment Funds and the principal risks that the Advisers and the Fund believe are associated with those investments. These principal risks will, in turn, have an effect on the Fund. In addition, the Fund may also make these types of investments pending the investment of assets in Infrastructure Assets or to maintain the liquidity necessary to effect repurchases of Shares. When the Fund takes a defensive position or otherwise makes these types of investments, it may not achieve its investment objectives. Principal Investment Related Risks General Economic and Market Conditions An investment in the Fund involves a high degree of risk, including the risk that the Shareholder’s entire investment may be lost. The Fund’s performance depends largely upon the Advisers’ selection of Infrastructure Assets, the allocation of offering proceeds thereto and the performance of the Infrastructure Assets. The Fund’s investment activities involve the risks associated with private market investments generally. Risks include adverse changes in national or international economic conditions, adverse local market conditions, the financial conditions of portfolio companies, changes in the availability or terms of financing, changes in interest rates, exchange rates, corporate tax rates and other operating expenses, environmental laws and regulations, and other governmental rules and fiscal policies, energy prices, changes in the relative popularity of certain industries or the availability of purchasers to acquire companies, and dependence on cash flow, as well as acts of God, uninsurable losses, war, terrorism, earthquakes, hurricanes or floods and other factors which are beyond the control of the Fund or the Private Market Assets. Unexpected volatility or lack of liquidity, such as the general market conditions that had prevailed in 2008, could impair the Fund’s profitability or result in its suffering losses. No Operating History. non-diversified, closed-end start-up Closed-end non-diversified, closed-end Closed-end open-end closed-end Availability of Investment Opportunities Similarly, identification of attractive investment opportunities by Investment Managers is difficult and involves a high degree of uncertainty. Even if an attractive investment opportunity is identified by an Investment Manager, it may not be permitted to take advantage of the opportunity to the fullest extent desired. Other investment vehicles sponsored, managed or advised by the Advisers and their affiliates may seek investment opportunities similar to those the Fund may be seeking. The Advisers will allocate fairly between the Fund and such other investment vehicles any investment opportunities that may be appropriate for the Fund and such other investment vehicles. See “Conflicts of Interest — The Advisers.” Leverage Utilized by the Fund i.e. The use of leverage is speculative and involves certain risks. Although leverage will increase the Fund’s investment return if the Fund’s interest in an asset purchased with borrowed funds earns a greater return than the interest expense the Fund pays for the use of those funds, the use of leverage will decrease the return on the Fund if the Fund fails to earn as much on its investment purchased with borrowed funds as it pays for the use of those funds. The use of leverage will in this way magnify the volatility of changes in the value of an investment in the Fund, especially in times of a “credit crunch” or during general market turmoil, such as that experienced during late 2008. The Fund may be required to maintain minimum average balances in connection with its borrowings or to pay a commitment or other fee to maintain a line of credit; either of these requirements would increase the cost of borrowing over the stated interest rate. In addition, a lender to the Fund may terminate or refuse to renew any credit facility into which the Fund has entered. If the Fund is unable to access additional credit, it may be forced to sell its interests in Investment Funds at inopportune times, which may further depress the returns of the Fund. The 1940 Act’s Asset Coverage Requirement requires a registered investment company to satisfy an asset coverage requirement of 300% of its indebtedness, including amounts borrowed, measured at the time the investment company incurs the indebtedness. This requirement means that the value of the investment company’s total indebtedness may not exceed one third of the value of its total assets (including the indebtedness). The 1940 Act also requires that dividends may not be declared if this Asset Coverage Requirement is breached. The Fund’s borrowings will at all times be subject to the Asset Coverage Requirement. Private Equity Investments. e.g. The regulatory environment for private investment funds continues to evolve, and changes in the regulation of private investment funds may adversely affect the value of the Fund’s investments and the ability of the Fund to implement its investment strategy (including the use of leverage). The financial services industry generally and the activities of private investment funds and their investment advisers, in particular, have been the subject of increasing legislative and regulatory scrutiny. Such scrutiny may increase the Fund’s and/or the Advisers’ legal, compliance, administrative and other related burdens and costs as well as regulatory oversight or involvement in the Fund and/or the Advisers’ business. There can be no assurances that the Fund or the Advisers will not in the future be subject to regulatory review or discipline. The effects of any regulatory changes or developments on the Fund may affect the manner in which it is managed and may be substantial and adverse. Investments in the Debt Securities of Small or Middle-Market Portfolio Companies • have reduced access to the capital markets, resulting in diminished capital resources and the ability to withstand financial distress; • may have limited financial resources and may be unable to meet their obligations under their debt securities, which may be accompanied by a deterioration in the value of any collateral and a reduction in the likelihood of realizing any guarantees that may have obtained in connection with the investment; • may have shorter operating histories, narrower product lines and smaller market shares than larger businesses, which tend to render them more vulnerable to competitors’ actions and changing market conditions, as well as general economic downturns; • generally, are more likely to depend on the management talents and efforts of a small group of persons; therefore, the death, disability, resignation or termination of one or more of these persons could have a material adverse impact on a portfolio company and, in turn, on the Investment Fund that has invested in the portfolio company; and • generally, have less predictable operating results, may from time to time be parties to litigation, may be engaged in rapidly changing businesses with products subject to a substantial risk of obsolescence, and may require substantial additional capital to support their operations, finance expansion or maintain their competitive position. Investments in smaller capitalization companies often involve significantly greater risks than the securities of larger, better-known companies because they may lack the management expertise, financial resources, product diversification and competitive strengths of larger companies. The prices of the securities of smaller companies may be subject to more abrupt or erratic market movements than those of larger, more established companies, as these securities typically are less liquid, traded in lower volume and the issuers typically are more subject to changes in earnings and prospects. In addition, when selling large positions in small capitalization securities, the seller may have to sell holdings at discounts from quoted prices or may have to make a series of small sales over a period of time. Further, smaller capitalization companies may be particularly affected by interest rate increases, as they may find it more difficult to borrow money to continue or expand operations or may have difficulty in repaying any loans. In addition, investments in private companies tend to be less liquid. The securities of many of the companies in which we invest are not publicly traded or actively traded on the secondary market and are, instead, traded on a privately negotiated over-the-counter Infrastructure Sector Risk. i.e., Co-Investment’s Specific Infrastructure Assets in which the Fund invests may be subject to the following additional risks: • Communication infrastructure companies are subject to risks involving changes in government regulation, competition, dependency on patent protection, equipment incompatibility, changing consumer preferences, technological obsolescence and large capital expenditures and debt burdens. • Energy infrastructure companies are subject to adverse changes in fuel prices, the effects of energy conservation policies and other risks, such as increased regulation, negative effects of economic slowdowns, reduced demand, cleanup and litigation costs as a result of environmental damage, changing and international politics and regulatory policies of various governments. Natural disasters or terrorist attacks damaging sources of energy supplies will also negatively impact energy infrastructure companies. • Social infrastructure companies/issuers are subject to government regulation and the costs of compliance with such regulations and delays or failures in receiving required regulatory approvals. The enactment of new or additional regulatory requirements may negatively affect the business of a social infrastructure company. • Transportation infrastructure companies can be significantly affected by economic changes, fuel prices, labor relations, insurance costs and government regulations. Transportation infrastructure companies will also be negatively impacted by natural disasters or terrorist attacks. • Utilities company revenues and costs are subject to regulation by states and other regulators. Regulatory authorities also may restrict a company’s access to new markets. Utilities companies may incur unexpected increases in fuel and other operating costs. Utilities companies are also subject to considerable costs associated with environmental compliance, nuclear waste clean-up Real Estate Investments. sub-prime Real estate assets are subject to risks associated with the ownership of real estate, including (i) changes in general economic and market conditions; (ii) changes in the value of real estate properties; (iii) risks related to local economic conditions, overbuilding and increased competition; (iv) increases in property taxes and operating expenses; (v) changes in zoning laws; (vi) casualty and condemnation losses; (vii) variations in rental income, neighborhood values or the appeal of property to tenants; (viii) the availability of financing and (ix) changes in interest rates. Many real estate companies utilize leverage, which increases investment risk and could adversely affect a company’s operations and market value in periods of rising interest rates. The value of securities of companies in the real estate industry may go through cycles of relative under-performance and over-performance in comparison to equity securities markets in general. There are also special risks associated with particular real estate sectors, or real estate operations generally, as described below: • Retail Properties. • Office Properties. non-competitiveness. • Industrial Properties • Hospitality Properties. • Healthcare Properties. • Multifamily Properties. • Residential Properties. fluctuations which can cause changes in the availability of mortgage capital and directly affect the purchasing power of potential homebuyers. Thus, residential properties can be significantly affected by changes in government spending, consumer confidence, demographic patterns and the level of new and existing home sales. • Shopping Centers. co-tenancy • Self-Storage Properties. Other factors may contribute to the risk of real estate investments: • Development Issues. • Lack of Insurance. • Dependence on Tenants. • Financial Leverage. • Environmental Issues. Energy Sector Risk impact on the assets focused on this sector. Additionally, the energy sector is a highly regulated industry both domestically and internationally which can also have a material impact on the investments in this sector. Other factors that may adversely affect the value of securities of companies in the energy sector include operational risks, challenges to exploration and production, competition, inability to make accretive acquisitions, significant accident or event that is not fully insured at a company, natural depletion of reserves, and other unforeseen natural disasters. Energy sector investments are affected by worldwide energy prices and costs related to energy production. These investments may have significant operations in areas at risk for natural disasters, social unrest and environmental damage. These investments may also be at risk for increased government regulation and intervention, energy conservation efforts, litigation and negative publicity and perception. Utilities Sector. Special Situations and Distressed Investments. Venture Capital and Growth Equity. Growth equity is usually classified by investments in private companies that have achieved product-market fit but may still need capital to achieve the desired level of scale before having access to the public markets for financing. As a result of the risks associated with advancing the company’s growth plan, investors can expect a higher return than might be available in the public markets, but also need to recognize the business and financial risks that remain in advancing the company’s commercial aspirations. For both venture capital and growth equity companies, the risks are generally greater than the risks of investing in public companies that may be at a later stage of development. Agriculture and Forestry Sector Risk operating expenses, environmental laws and regulations, governmental regulation of and risks associated with the use of fertilizers, pesticides, herbicides and other chemicals used in commercial agriculture, zoning laws and other governmental rules and fiscal policies, energy prices, changes in the relative popularity of properties, risk due to dependence on cash flow, as well as acts of God, uninsurable losses and other factors which are beyond the control of the Fund or an Investment Fund. In addition, the forestry and timber industry is highly cyclical and the market value of timber investments is strongly affected by changes in international economic conditions, interest rates, weather cycles, changing demographics, environmental conditions and government regulations, among other factors. For example, the volume and value of timber that can be harvested from timberlands is limited by natural disasters, fire, volcanic eruptions, insect infestation, disease, ice storms, windstorms, flooding and other events and weather conditions and changes in climate conditions could intensify the effects of any of these factors. Many companies in the timber and forestry industry do not insure against damages to their timberlands. This industry is also subject to stringent U.S. federal, state and local environmental, health and safety laws and regulations. Significant timber deposits are located in emerging markets countries where corruption and security may raise significant risks. Financial Institutions Risk. U.S. and global markets recently have experienced increased volatility, including as a result of the recent failures of certain U.S. and non-U.S. Geographic Concentration Risks. Emerging Markets. China is an emerging market and has demonstrated significantly higher volatility from time to time in comparison to developed markets. Investments in Chinese securities, including certain Hong Kong-listed and U.S.-listed securities, subject the Fund to risks specific to China. These risks include: (i) the risk of more frequent (and potentially widespread) trading suspensions and government interventions with respect to Chinese issuers, resulting in liquidity risk, price volatility, greater market execution risk, and valuation risk; (ii) the risk of currency fluctuations, currency non-convertibility, Sector Concentration. Technology Sector. Financial Sector. Currency Risk. Non-U.S. Non-U.S. non-U.S. non-U.S. other matters; (iii) differences between the U.S. and non-U.S. non-U.S. non-U.S. non-U.S. Additionally, certain Infrastructure Assets may include or invest in foreign portfolio companies that do not maintain internal management accounts or adopt financial budgeting, internal audit or internal control procedures to standards normally expected of companies in the United States. Accordingly, information supplied regarding the Private Market Assets may be incomplete, inaccurate and/or significantly delayed. The Fund and the Investment Funds may therefore be unable to take or influence timely actions necessary to rectify management deficiencies in such portfolio companies, which may ultimately have an adverse impact on the NAV of the Fund. The Fund’s Infrastructure Assets could be negatively impacted by the current hostilities in Eastern Europe, including direct and indirect effects on their operations and financial condition. In the event these hostilities escalate, the impact could more significant. Certain of the Infrastructure Assets in which the Fund may invest may operate in, or have dealings with, countries subject to sanctions or embargos imposed by the U.S. government, foreign governments, or the United Nations or other international organizations. In particular, as a result of recent events involving Ukraine and Russia, the United States and other countries have imposed economic sanctions on Russian sovereign debt and on certain Russian individuals, financial institutions, and others. Sanctions could result in Russia taking counter measures or retaliatory actions which may further impair the value and liquidity of Russian securities. These sanctions could also impair the Fund’s ability to meet its investment objectives. For example, the Fund may be prohibited from investing in securities issued by companies subject to such sanctions. In addition, the sanctions may require the Fund to freeze its existing investments in companies operating in or having dealings with sanctioned countries, prohibiting the Fund from selling or otherwise transacting in these investments. This could impact the Fund’s ability to sell securities or other financial instruments as needed to meet shareholder redemptions. The Fund could seek to suspend redemptions in the event that an emergency exists in which it is not reasonably practicable for the Fund to dispose of its securities or to determine the value of its net assets. Illiquidity of Infrastructure Assets. Investments in Non-Voting non-voting non-voting Nature of Portfolio Companies. management, or a proven market for their products. The Fund’s investments may also include portfolio companies that are in a state of distress or which have a poor record and which are undergoing restructuring or changes in management, and there can be no assurances that such restructuring or changes will be successful. The management of such portfolio companies may depend on one or two key individuals, and the loss of the services of any of such individuals may adversely affect the performance of such portfolio companies. Investments in the Debt Securities of Small or Middle-Market Portfolio Companies. • have reduced access to the capital markets, resulting in diminished capital resources and the ability to withstand financial distress; • may have limited financial resources and may be unable to meet their obligations under their debt securities, which may be accompanied by a deterioration in the value of any collateral and a reduction in the likelihood of realizing any guarantees that may have obtained in connection with the investment; • may have shorter operating histories, narrower product lines and smaller market shares than larger businesses, which tend to render them more vulnerable to competitors’ actions and changing market conditions, as well as general economic downturns; • generally, are more likely to depend on the management talents and efforts of a small group of persons; therefore, the death, disability, resignation or termination of one or more of these persons could have a material adverse impact on a portfolio company and, in turn, on the Investment Fund that has invested in the portfolio company; and • generally, have less predictable operating results, may from time to time be parties to litigation, may be engaged in rapidly changing businesses with products subject to a substantial risk of obsolescence, and may require substantial additional capital to support their operations, finance expansion or maintain their competitive position. Investments in smaller capitalization companies often involve significantly greater risks than the securities of larger, better-known companies because they may lack the management expertise, financial resources, product diversification and competitive strengths of larger companies. The prices of the securities of smaller companies may be subject to more abrupt or erratic market movements than those of larger, more established companies, as these securities typically are less liquid, traded in lower volume and the issuers typically are more subject to changes in earnings and prospects. In addition, when selling large positions in small capitalization securities, the seller may have to sell holdings at discounts from quoted prices or may have to make a series of small sales over a period of time. In addition, investments in private companies tend to be less liquid. The securities of many of the companies in which we invest are not publicly traded or actively traded on the secondary market and are, instead, traded on a privately negotiated over-the-counter First Lien Senior Secured Loans, Second Lien Senior Secured Loans and Unitranche Debt portfolio company’s financial condition and prospects, including its inability to raise additional capital, may be accompanied by deterioration in the value of the collateral for the loan. Loans that are under- collateralized involve a greater risk of loss. Consequently, the fact that a loan is secured does not guarantee that we will receive principal and interest payments according to the loan’s terms, or at all, or that we will be able to collect on the loan should the remedies be enforced. Finally, particularly with respect to a unitranche debt structure, unitranche debt will generally have higher leverage levels than a standard first lien term loan. Mezzanine Investments. Risks Associated with Covenant-Lite Loans. High Yield Securities and Distressed Securities non-investment Non-investment Non-investment non-investment Non-investment Non-investment Non-investment non-investment Certain Infrastructure Assets may be in transition, out of favor, financially leveraged or troubled, or potentially troubled, and may be or have recently been involved in major strategic actions, restructurings, bankruptcy, reorganization or liquidation. The characteristics of these companies can cause their securities to be particularly risky, although they also may offer the potential for high returns. These companies’ securities may be considered speculative, and the ability of the companies to pay their debts on schedule could be affected by adverse interest rate movements, changes in the general economic climate, economic factors affecting a particular industry or specific developments within the companies. These securities may also present a substantial risk of default. An Investment Fund’s or the Fund’s investment in any instrument is subject to no minimum credit standard and a significant portion of the obligations and preferred stock in which an Investment Fund or the Fund may invest may be non-investment Primary Investments LIBOR Risk. mid-2023. The termination of certain Reference Rates presents risks to the Fund. The elimination of a Reference Rate or any other changes or reforms to the determination or supervision of Reference Rates could have an adverse impact on the market for or value of any securities or payments linked to those Reference Rates and other financial obligations held by the Fund or on its overall financial condition or results of operations. In addition, any substitute Reference Rate and any pricing adjustments imposed by a regulator or by counterparties or otherwise may adversely affect the Fund’s performance and/or NAV. The transition process away from LIBOR may involve, among other things, increased volatility or illiquidity in markets for instruments that currently rely on LIBOR. The transition process may also result in a reduction in the value of certain instruments held by the Fund or reduce the effectiveness of related Fund transactions. While some instruments in which the Fund invests may contemplate a scenario where LIBOR is no longer available by providing for an alternative rate setting methodology, not all instruments in which the Fund invests may have such provisions and there is significant uncertainty regarding the effectiveness of any such alternative methodologies. Any potential effects of the transition away from LIBOR on the Fund or on financial instruments in which the Fund invests, as well as other unforeseen effects, could result in losses to the Fund. Since the usefulness of LIBOR as a benchmark or reference rate could deteriorate during the transition period, these effects could occur prior to and/or subsequent to mid-2023. The risks set out above are heightened with respect to investments in LIBOR-based products that do not include a fall back provision that addresses how interest rates will be determined if LIBOR stops being published. Other important factors include the pace of the transition, the specific terms of alternative Reference Rates accepted in the market, the depth of the market for investments based on alternative reference rates, and the Advisers’ ability to develop appropriate investment and compliance systems capable of addressing alternative Reference Rates. Force Majeure Risk . i.e. The outbreak of a novel coronavirus (“SARS-CoV-2”) (“COVID-19”) global markets and economies affected thereby. The COVID-19 “non-essential,” COVID-19 COVID-19 pre-existing Similar consequences could arise with respect to other infectious diseases. Principal Risks Related to Infrastructure Assets Infrastructure Investments Generally. co-investments Investments will be subject to the risks incidental to the indirect ownership and operation of infrastructure assets, including risks associated with the general economic climate, geographic or market concentration, climatic risks, the ability of the third-party sponsors to manage the investment, government regulations, national and international political circumstances and fluctuations in interest rates, rates of inflation or commodities’ prices such as oil. Since investments in infrastructure and similar assets, like many other types of long-term investments, have historically experienced significant fluctuations and cycles in value, specific market conditions may result in temporary or permanent reductions in the value of an investment. In addition, general economic conditions in relevant jurisdictions, as well as conditions of domestic and international financial markets, may adversely affect operations of the third-party co-investors time-lag There can be no assurance that the Investments will be profitable or generate cash flow sufficient to provide a return on or recovery of amounts invested therein. Sector Risks. The occurrence of events related to any of the foregoing could have a material adverse effect on the Fund and its Co-Investments. Co-Investments. Environmental, Health and Safety Risks. Co-Investments non-compliance Co-Investment material administrative, civil, or criminal penalties or other liabilities. Further, under various statutes, rules and regulations of certain jurisdictions, a current or previous owner or operator of real property may be liable for the costs of investigation, monitoring, removal or remediation of hazardous materials, in some cases whether or not the owner or operator knew of or was responsible for the presence of hazardous materials. The presence of hazardous materials on a property could also result in personal injury or property damage or similar claims by private parties. Persons who arrange for the disposal or treatment of hazardous materials may also be liable for the costs of removal or remediation of these materials at the disposal or treatment facility, whether or not that facility is or ever was owned or operated by that person. The long-term trend toward increasingly stringent environmental, health, and safety regulation could continue in the future, resulting in substantial additional costs on Co-Investments Co-Investment, Co-Investment.

Co-Investments Co-Investments, Co-Investments In addition, infrastructure investments may be subject to rate regulation by government agencies because of their unique position as the sole or predominant providers of services that are often essential to the community. As a result, certain infrastructure investments might be subject to unfavorable price regulation by government agencies. Political oversight of the sector is also likely to remain pervasive and unpredictable and, for political reasons, governments may attempt to take actions which may negatively affect the operations, revenue, profitability or contractual relationships of infrastructure investments, including through expropriation. Certain infrastructure investments may need to use public ways or may operate under easements. Under the terms of agreements governing the use of public ways or easements, government authorities may retain the right to restrict the use of such public ways or easements or to require portfolio companies to remove, modify, replace or relocate their facilities at the portfolio company’s expense. If a government authority exercises these rights, the portfolio company could incur significant costs and its ability to provide service to its customers could be disrupted, which could adversely impact the performance of the relevant Co-Investment. Infrastructure assets are often governed by highly complex legal contracts and documents. As a result, the risks of a dispute over interpretation or enforceability of the legal contracts and documentation and consequent costs and delays may be higher than for other types of investments. Such risks may be increased by the uncertainty of laws and their application in certain jurisdictions in which the Fund will invest. The Fund may be adversely affected by future changes in laws and regulations. Other legal risks relate to environmental issues and industrial actions or to actions by special interest groups and actions or litigation relating to the acquisition, ownership, operation and disposition of the Co-Investments may adversely affect the Co-Investment Demand and Usage Risk.

The Fund’s performance depends largely upon the Advisers’ selection of Infrastructure Assets, the allocation of offering proceeds thereto and the performance of the Infrastructure Assets. The Fund’s investment activities involve the risks associated with private market investments generally. Risks include adverse changes in national or international economic conditions, adverse local market conditions, the financial conditions of portfolio companies, changes in the availability or terms of financing, changes in interest rates, exchange rates, corporate tax rates and other operating expenses, environmental laws and regulations, and other governmental rules and fiscal policies, energy prices, changes in the relative popularity of certain industries or the availability of purchasers to acquire companies, and dependence on cash flow, as well as acts of God, uninsurable losses, war, terrorism, earthquakes, hurricanes or floods and other factors which are beyond the control of the Fund or the Private Market Assets. Unexpected volatility or lack of liquidity, such as the general market conditions that had prevailed in 2008, could impair the Fund’s profitability or result in its suffering losses.

Risk [Text Block]		Energy Sector Risk impact on the assets focused on this sector. Additionally, the energy sector is a highly regulated industry both domestically and internationally which can also have a material impact on the investments in this sector. Other factors that may adversely affect the value of securities of companies in the energy sector include operational risks, challenges to exploration and production, competition, inability to make accretive acquisitions, significant accident or event that is not fully insured at a company, natural depletion of reserves, and other unforeseen natural disasters. Energy sector investments are affected by worldwide energy prices and costs related to energy production. These investments may have significant operations in areas at risk for natural disasters, social unrest and environmental damage. These investments may also be at risk for increased government regulation and intervention, energy conservation efforts, litigation and negative publicity and perception.

General Description of Registrant [Abstract]
Risk [Text Block]		Venture Capital and Growth Equity. Growth equity is usually classified by investments in private companies that have achieved product-market fit but may still need capital to achieve the desired level of scale before having access to the public markets for financing. As a result of the risks associated with advancing the company’s growth plan, investors can expect a higher return than might be available in the public markets, but also need to recognize the business and financial risks that remain in advancing the company’s commercial aspirations. For both venture capital and growth equity companies, the risks are generally greater than the risks of investing in public companies that may be at a later stage of development.

Risk [Text Block]		Agriculture and Forestry Sector Risk operating expenses, environmental laws and regulations, governmental regulation of and risks associated with the use of fertilizers, pesticides, herbicides and other chemicals used in commercial agriculture, zoning laws and other governmental rules and fiscal policies, energy prices, changes in the relative popularity of properties, risk due to dependence on cash flow, as well as acts of God, uninsurable losses and other factors which are beyond the control of the Fund or an Investment Fund. In addition, the forestry and timber industry is highly cyclical and the market value of timber investments is strongly affected by changes in international economic conditions, interest rates, weather cycles, changing demographics, environmental conditions and government regulations, among other factors. For example, the volume and value of timber that can be harvested from timberlands is limited by natural disasters, fire, volcanic eruptions, insect infestation, disease, ice storms, windstorms, flooding and other events and weather conditions and changes in climate conditions could intensify the effects of any of these factors. Many companies in the timber and forestry industry do not insure against damages to their timberlands. This industry is also subject to stringent U.S. federal, state and local environmental, health and safety laws and regulations. Significant timber deposits are located in emerging markets countries where corruption and security may raise significant risks.

Accordingly, information supplied regarding the Private Market Assets may be incomplete, inaccurate and/or significantly delayed. The Fund and the Investment Funds may therefore be unable to take or influence timely actions necessary to rectify management deficiencies in such portfolio companies, which may ultimately have an adverse impact on the NAV of the Fund. The Fund’s Infrastructure Assets could be negatively impacted by the current hostilities in Eastern Europe, including direct and indirect effects on their operations and financial condition. In the event these hostilities escalate, the impact could more significant. Certain of the Infrastructure Assets in which the Fund may invest may operate in, or have dealings with, countries subject to sanctions or embargos imposed by the U.S. government, foreign governments, or the United Nations or other international organizations. In particular, as a result of recent events involving Ukraine and Russia, the United States and other countries have imposed economic sanctions on Russian sovereign debt and on certain Russian individuals, financial institutions, and others. Sanctions could result in Russia taking counter measures or retaliatory actions which may further impair the value and liquidity of Russian securities. These sanctions could also impair the Fund’s ability to meet its investment objectives. For example, the Fund may be prohibited from investing in securities issued by companies subject to such sanctions. In addition, the sanctions may require the Fund to freeze its existing investments in companies operating in or having dealings with sanctioned countries, prohibiting the Fund from selling or otherwise transacting in these investments. This could impact the Fund’s ability to sell securities or other financial instruments as needed to meet shareholder redemptions. The Fund could seek to suspend redemptions in the event that an emergency exists in which it is not reasonably practicable for the Fund to dispose of its securities or to determine the value of its net assets.

Loans that are under- collateralized involve a greater risk of loss. Consequently, the fact that a loan is secured does not guarantee that we will receive principal and interest payments according to the loan’s terms, or at all, or that we will be able to collect on the loan should the remedies be enforced. Finally, particularly with respect to a unitranche debt structure, unitranche debt will generally have higher leverage levels than a standard first lien term loan.

The characteristics of these companies can cause their securities to be particularly risky, although they also may offer the potential for high returns. These companies’ securities may be considered speculative, and the ability of the companies to pay their debts on schedule could be affected by adverse interest rate movements, changes in the general economic climate, economic factors affecting a particular industry or specific developments within the companies.

General Description of Registrant [Abstract]
Risk [Text Block]		LIBOR Risk. mid-2023. The termination of certain Reference Rates presents risks to the Fund. The elimination of a Reference Rate or any other changes or reforms to the determination or supervision of Reference Rates could have an adverse impact on the market for or value of any securities or payments linked to those Reference Rates and other financial obligations held by the Fund or on its overall financial condition or results of operations. In addition, any substitute Reference Rate and any pricing adjustments imposed by a regulator or by counterparties or otherwise may adversely affect the Fund’s performance and/or NAV. The transition process away from LIBOR may involve, among other things, increased volatility or illiquidity in markets for instruments that currently rely on LIBOR. The transition process may also result in a reduction in the value of certain instruments held by the Fund or reduce the effectiveness of related Fund transactions. While some instruments in which the Fund invests may contemplate a scenario where LIBOR is no longer available by providing for an alternative rate setting methodology, not all instruments in which the Fund invests may have such provisions and there is significant uncertainty regarding the effectiveness of any such alternative methodologies. Any potential effects of the transition away from LIBOR on the Fund or on financial instruments in which the Fund invests, as well as other unforeseen effects, could result in losses to the Fund. Since the usefulness of LIBOR as a benchmark or reference rate could deteriorate during the transition period, these effects could occur prior to and/or subsequent to mid-2023. The risks set out above are heightened with respect to investments in LIBOR-based products that do not include a fall back provision that addresses how interest rates will be determined if LIBOR stops being published. Other important factors include the pace of the transition, the specific terms of alternative Reference Rates accepted in the market, the depth of the market for investments based on alternative reference rates, and the Advisers’ ability to develop appropriate investment and compliance systems capable of addressing alternative Reference Rates.

Since investments in infrastructure and similar assets, like many other types of long-term investments, have historically experienced significant fluctuations and cycles in value, specific market conditions may result in temporary or permanent reductions in the value of an investment. In addition, general economic conditions in relevant jurisdictions, as well as conditions of domestic and international financial markets, may adversely affect operations of the third-party co-investors time-lag There can be no assurance that the Investments will be profitable or generate cash flow sufficient to provide a return on or recovery of amounts invested therein.

Co-Investments Co-Investments, Co-Investments In addition, infrastructure investments may be subject to rate regulation by government agencies because of their unique position as the sole or predominant providers of services that are often essential to the community. As a result, certain infrastructure investments might be subject to unfavorable price regulation by government agencies. Political oversight of the sector is also likely to remain pervasive and unpredictable and, for political reasons, governments may attempt to take actions which may negatively affect the operations, revenue, profitability or contractual relationships of infrastructure investments, including through expropriation. Certain infrastructure investments may need to use public ways or may operate under easements. Under the terms of agreements governing the use of public ways or easements, government authorities may retain the right to restrict the use of such public ways or easements or to require portfolio companies to remove, modify, replace or relocate their facilities at the portfolio company’s expense. If a government authority exercises these rights, the portfolio company could incur significant costs and its ability to provide service to its customers could be disrupted, which could adversely impact the performance of the relevant Co-Investment. Infrastructure assets are often governed by highly complex legal contracts and documents. As a result, the risks of a dispute over interpretation or enforceability of the legal contracts and documentation and consequent costs and delays may be higher than for other types of investments. Such risks may be increased by the uncertainty of laws and their application in certain jurisdictions in which the Fund will invest. The Fund may be adversely affected by future changes in laws and regulations. Other legal risks relate to environmental issues and industrial actions or to actions by special interest groups and actions or litigation relating to the acquisition, ownership, operation and disposition of the Co-Investments may adversely affect the Co-Investment

Risk [Text Block]		General Risks of Secondary Investments. Co-Investment e.g. Where the Fund acquires a secondary Investment Fund, the Fund may acquire contingent liabilities associated with such interest. Specifically, where the seller has received distributions from the relevant secondary Investment Fund and, subsequently, that secondary Investment Fund recalls any portion of such distributions, the Fund (as the purchaser of the interest to which such distributions are attributable) may be obligated to pay an amount equivalent to such distributions to such secondary Investment Fund. While the Fund may be able, in turn, to make a claim against the seller of the interest for any monies so paid to the secondary Investment Fund, there can be no assurance that the Fund would have such right or prevail in any such claim. The Fund may acquire Secondary Investments as a member of a purchasing syndicate, in which case the Fund may be exposed to additional risks including, among other things: (i) counterparty risk, (ii) reputation risk, (iii) breach of confidentiality by a syndicate member, and (iv) execution risk. Additionally, the Fund may acquire interests in Secondary Investments through structured transactions such as collateralized fund obligations (“CFOs”) or similar investment vehicles that own existing secondaries and co-investments.
Commitment Strategy [Member]
General Description of Registrant [Abstract]
Risk [Text Block]		Commitment Strategy The Fund will employ an “over-commitment” strategy, which could result in an insufficient cash supply to fund unfunded commitments to Investment Funds. Such a short fall would have negative impacts on the Fund, including an adverse impact on the Fund’s ability to pay for redemptions of Shares by Shareholders, pay distributions or to meet expenses generally. Moreover, if the Fund defaults on its unfunded commitments or fails to satisfy capital calls in a timely manner then, generally, it will be subject to significant penalties, including the complete forfeiture of the Fund’s investment in the Investment Fund. Any failure by the Fund to make timely capital contributions in respect of its unfunded commitments may (i) impair the ability of the Fund to pursue its investment program, (ii) force the Fund to borrow, indirectly cause the Fund, and, indirectly, the Shareholders to be subject to certain penalties from the Investment Funds (including the complete forfeiture of the Fund’s investment in an Investment Fund), or (iv) otherwise impair the value of the Fund’s investments (including the devaluation of the Fund).

In order to address these conflicts of interest, the Firm adopted allocation policies and procedures that were designed to require that all investment allocation decisions made by the investment team are being made fairly and equitably among Related Investment Accounts over time. Subject to applicable law, the Firm will allocate opportunities among the Fund and the Related Investment Accounts in its sole discretion. The Firm will determine such allocations among its Related Investment Accounts in its sole discretion in accordance with their respective guidelines and based on such factors and considerations as it deems appropriate.

[1]Investors purchasing Class T and Class S Shares may be charged a sales load of up to 3.50% of the investment amount. The table assumes the maximum sales load is charged. A Selling Agent may, in its discretion, waive all or a portion of the sales load for certain investors. See “Plan of Distribution.”[2]These expenses represent estimated interest payments the Fund expects to incur in connection with its credit facility during the 12 months ending June 30, 2025. See “Investment Program — Leverage.”[3]The “Acquired Fund Fees and Expenses” are based on estimated amounts for the 12 months ending June 30, 2025. Some or all of the Investment Funds in which the Fund intends to invest charge carried interests, incentive fees or allocations based on the Investment Funds’ performance. The Investment Funds in which the Fund intends to invest generally charge a management fee of 1.00% to 2.00% based on committed capital, and approximately 15% to 20% of net profits as a carried interest allocation. The Acquired Fund Fees and Expenses disclosed above are based on historic returns of the Investment Funds in which the Fund anticipates investing in for the 12 months ending June 30, 2025, which may change substantially over time and, therefore, significantly affect “Acquired Fund Fees and Expenses.” The 0.60% shown as Acquired Fund Fees and Expenses reflects operating expenses of the Investment Funds (e.g., management fees, administration fees and professional and other direct, fixed fees and expenses of the Investment Funds) after refunds, excluding any performance-based fees or allocations paid by the Investment Funds that are paid solely on the realization and/or distribution of gains, or on the sum of such gains and unrealized appreciation of assets distributed in-kind, as such fees and allocations for a particular period may be unrelated to the cost of investing in the Investment Funds.[4]Includes amounts paid under an administration agreement (the “Administration Agreement”) between the Fund and StepStone Private Wealth as administrator (the “Administrator”). Under the Administration Agreement, the Fund pays the Administrator an administration fee (the “Administration Fee”) in an amount up to 0.23% on an annualized basis of the Fund’s net assets. From the proceeds of the Administration Fee, the Administrator pays UMB Fund Services, Inc. (the “Sub-Administrator”) a sub-administration fee (the “Sub-Administration Fee”) in an amount up to 0.08% on an annualized basis of the Fund’s net assets, subject to a minimum annual fee. The Sub-Administration Fee is paid pursuant to a sub-administration agreement and a fund accounting agreement each between the Administrator and the Sub-Administrator. The Administration Fee is accrued daily based on the value of the net assets of the Fund as of the close of business on each business day (including any assets in respect of shares that is repurchased by the Fund on such date) and payable in arrears within ten business days after the end of the month. The Sub-Administration Fee is calculated in a manner substantially similar to the Administration Fee and is payable monthly in arrears.[5]Other Expenses include all other expenses incurred by the Fund, such as its organizational and offering expenses, certain administrative costs and expenses relating to the offering and sale of Shares. Other Expenses are estimated for the 12 months ending June 30, 2025.[6]The Adviser has entered into an Expense Limitation and Reimbursement Agreement with the Fund for the Limitation Period. The Adviser may extend the Limitation Period for a period of one year on an annual basis. The Expense Limitation and Reimbursement Agreement limits the amount of the Fund’s aggregate ordinary operating expenses, excluding certain Specified Expenses listed below, borne by the Fund during the Limitation Period to an amount not to exceed 1.00% for Class T, S, D and I Shares, on an annualized basis, of the Fund’s daily net assets or the Expense Cap. “Specified Expenses” that are not covered by the Expense Limitation and Reimbursement Agreement include: (i) the Management Fee; (ii) all fees and expenses of Private Market Assets and other investments in which the Fund invests (including the underlying fees of the Private Market Assets and other investments (the Acquired Fund Fees and Expenses)); (iii) transactional costs, including legal costs and brokerage commissions, associated with the acquisition and disposition of Private Market Assets and other investments; (iv) interest payments incurred on borrowing by the Fund; (v) fees and expenses incurred in connection with a credit facility, if any, obtained by the Fund; (vi) distribution and/or shareholder servicing fees, as applicable; (vii) taxes; and (viii) extraordinary expenses resulting from events and transactions that are distinguished by their unusual nature and by the infrequency of their occurrence, including, without limitation, costs incurred in connection with any claim, litigation, arbitration, mediation, government investigation or similar proceeding, indemnification expenses, and expenses in connection with holding and/or soliciting proxies for all annual and other meetings of Shareholders. See “Fund Expenses” for additional information. If the Fund’s aggregate ordinary operating expenses, exclusive of the Specified Expenses, in respect of any Class of Shares for any day exceeding the Expense Cap applicable to that Class of Shares, the Adviser will waive its Management Fee and/or reimburse the Fund for expenses to the extent necessary to eliminate such excess. The Adviser may also directly pay expenses on behalf of the Fund and waive reimbursement under the Expense Limitation and Reimbursement Agreement. To the extent that the Adviser waives its Management Fee, reimburses expenses to the Fund or pays expenses directly on behalf of the Fund, it is permitted to recoup from the Fund any such amounts for a period not to exceed three years from the month in which such fees and expenses were waived, reimbursed, or paid, even if such recoupment occurs after the termination of the Limitation Period. However, the Adviser may only recoup the waived fees, reimbursed expenses or directly paid expenses in respect of the applicable Class of Shares if (i) the aggregate ordinary operating expenses have fallen to a level below the relevant Expense Cap and (ii) the recouped amount does not raise the level of aggregate ordinary operating expenses plus waived fees, reimbursed expenses or directly paid expenses in respect of a Class of Shares in the month of recoupment to a level that exceeds any Expense Cap applicable at that time.[7]Annual Net Expenses include expenses limited by the Fund’s Expense Limitation and Reimbursement Agreement.
