As with any investment, you could lose all or a substantial part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to certain risks, including the principal risks noted below. Any such risk may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

 

U S Treasury Obligations Risk [Member]

Risk [Text Block]

U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund’s U.S. Treasury obligations to decline.

 

Bond Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Bond Risk. The Fund invests a substantial portion of its assets in U.S. dollar-denominated bonds. A bond is an interest-bearing security typically issued by a corporate or government issuer that has a contractual obligation to pay interest at a stated rate on specific dates and to repay principal (the bond’s face value) periodically or on a specified maturity date. Bonds generally are used by corporations and governments to borrow money from investors. An issuer may have the right to redeem or “call” a bond before maturity, in which case the Fund may have to reinvest the proceeds at lower market rates. Similarly, the Fund may have to reinvest interest income or payments received when bonds mature, sometimes at lower market rates. Most bonds bear interest income at a “coupon” rate that is fixed for the life of the bond. The value of a fixed-rate bond usually rises when market interest rates fall, and falls when market interest rates rise. Bonds may be unsecured (backed only by the issuer’s general creditworthiness) or secured (backed by specified collateral).

 

High Yield Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

High Yield Securities Risk. Securities that are rated below investment-grade (sometimes referred to as “junk bonds,” which may include those bonds rated below “BBB-” by Standard & Poor’s® Global Ratings, a subsidiary of S&P Global (“S&P Global Ratings”) and Fitch Ratings, Inc. (“Fitch”) or below “Baa3” by Moody’s Investors Services, Inc.(“Moody’s”)), or similar securities that are unrated, may be deemed speculative, may involve greater levels of risk than higher-rated securities of similar maturity and may be more likely to default. High-yield debt securities’ total return and yield may generally be expected to fluctuate more than the total return and yield of investment-grade debt securities. A real or perceived economic downturn or an increase in market interest rates could cause a decline in the value of high-yield debt securities, result in increased redemptions and/or result in increased portfolio turnover, which could result in a decline in the NAV of the Fund, reduce liquidity for certain investments and/or increase costs. High-yield debt securities are often thinly traded and can be more difficult to sell and value accurately than investment-grade debt securities because there may be no established secondary market. Investments in high-yield debt securities could increase liquidity risk for the Fund. In addition, the market for high-yield debt securities could experience sudden and sharp volatility, which is generally associated more with investments in stocks.

 

Interest Rate Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Interest Rate Risk. During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns or pay dividends to Fund shareholders. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Additionally, under certain market conditions in which interest rates are low and the market prices for portfolio securities have increased, the Fund may have a very low, or even negative yield. A low or negative yield would cause the Fund to lose money in certain conditions and over certain time periods. The U.S. government and the U.S. Federal Reserve, as well as certain foreign governments and central banks, have from time to time taken steps to support financial markets. The U.S. government and the U.S. Federal Reserve may, conversely, reduce market support activities, including by taking action intended to increase certain interest rates. This and other government intervention may not work as intended, particularly if the efforts are perceived by investors as being unlikely to achieve the desired results. Changes in government activities in this regard, such as changes in interest rate policy, can negatively affect financial markets generally, increase market volatility and reduce the value and liquidity of securities in which the Fund invests.

 

Credit Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Credit Risk. Debt issuers and other counterparties may be unable or unwilling to make timely interest and/or principal payments when due or otherwise honor their obligations. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also adversely affect the value of the Fund’s investment in that issuer. The degree of credit risk depends on an issuer’s or counterparty’s financial condition and on the terms of an obligation.

 

Mortgagerelated And Assetbacked Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Mortgage-Related and Asset-Backed Securities Risk. Mortgage-related and asset-backed securities represent interests in “pools” of mortgages or other assets, including consumer loans or receivables held in trust. These mortgage-related or asset-backed securities are subject to credit risk, interest rate risk, “prepayment risk” (the risk that borrowers will repay a loan more quickly in periods of falling interest rates) and “extension risk” (the risk that borrowers will repay a loan more slowly in periods of rising interest rates). If the Fund invests in mortgage-related or asset-backed securities that are subordinated to other interests in the same mortgage or asset pool, the Fund may only receive payments after the pool’s obligations to other investors have been satisfied. An unexpectedly high rate of defaults on the mortgages held by a mortgage pool may limit substantially the pool’s ability to make payments of principal or interest to the Fund, reducing the values of those securities or in some cases rendering them worthless. Uniform Mortgage-Backed Securities, which generally align the characteristics of Fannie Mae and Freddie Mac certificates, are a recent innovation and the effect they may have on the market for mortgage-related securities is uncertain.

 

Cash Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cash Management Risk. If a significant amount of the Fund’s assets is invested in cash and cash equivalents, the Fund may underperform other funds that do not similarly invest in cash and cash equivalents for investment purposes and/or to collateralize derivative instruments.

 

Corporate Loans Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Corporate Loans Risk. Commercial banks and other financial institutions or institutional investors make corporate loans to companies that need capital to grow or restructure. Borrowers generally pay interest on corporate loans at rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate (“SOFR”), or the prime rates of U.S. banks. As a result, the value of corporate loan investments is generally less exposed to the adverse effects of shifts in market interest rates than investments that pay a fixed rate of interest. The market for corporate loans may be subject to irregular trading activity and wide bid/ask spreads. In addition, transactions in corporate loans may settle on a delayed basis. As a result, the proceeds from the sale of corporate loans may not be readily available to make additional investments or to meet the Fund’s redemption obligations. To the extent the extended settlement process gives rise to short-term liquidity needs, the Fund may hold additional cash, sell investments or temporarily borrow from banks and other lenders. The corporate loans in which the Fund invests are usually rated below investment grade.

 

Credit Spread Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Credit Spread Risk. Credit spread risk is the risk that credit spreads (i.e., the difference in yield between securities that have differences in credit quality or other factors) may increase, which may reduce the market values of certain or all of the Fund’s securities. While the Fund may employ strategies to mitigate credit spread risk, these strategies may not be successful.

 

Clo Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CLO Risk. The risks of investing in CLOs include both the economic risks of the underlying loans combined with the risks associated with the CLO structure governing the priority of payments. The degree of such risk will generally correspond to the specific tranche in which the Fund is invested. The Fund intends to invest primarily in the rated debt tranches of CLOs; however, any such ratings do not constitute a guarantee, may be downgraded, and in stressed market environments it is possible that even senior CLO tranches could experience losses due to actual defaults, increased sensitivity to defaults due to collateral default and the disappearance of the subordinated/equity tranches, market anticipation of defaults, as well as negative market sentiment with respect to CLO securities as an asset class. BIM may not be able to accurately predict how specific CLOs or the portfolio of underlying loans for such CLOs will react to changes or stresses in the market, including changes in interest rates. The most common risks associated with investing in CLOs are liquidity risk, interest rate risk, credit risk, prepayment risk, and the risk of default of the underlying asset, among others.

 

Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk. The Fund’s use of derivatives (e.g., futures, swaps, options) may be riskier than other types of investments and may not have the intended effect on the Fund’s performance. Derivatives can be sensitive to changes in economic and market conditions, and they may increase the Fund’s volatility. The Fund also may experience reduced returns as a result of transaction costs and losses on derivatives positions. There is the risk of imperfect correlation between the value of a derivative and that of the asset underlying the derivative. Derivatives may create investment leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives are subject to the risk of mispricing or improper valuation, particularly if there is not a liquid secondary market for the instrument. Certain derivatives are subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations. The use of derivatives also exposes the Fund to additional operational and legal risks.

 

Broadly Syndicated Bank Loans Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Broadly Syndicated Bank Loans Risk. The CLOs in which the Fund invests are typically composed of broadly syndicated loans (“BSLs”). BSLs are typically originated and structured by banks on behalf of large corporate borrowers. The proceeds of BSLs are often used for leveraged buyout transactions, mergers and acquisitions, recapitalizations, refinancings, and financing capital expenditures. BSLs are typically distributed by the arranging bank to a diverse group of investors primarily consisting of: CLOs; senior secured loan and high yield bond mutual funds; closed-end funds, hedge funds, banks, and insurance companies; and finance companies. A borrower must comply with various covenants contained in a loan agreement or note purchase agreement between the borrower and the holders of the broadly syndicated loan. Investments in BSLs may expose the Fund to different risks, including with respect to liquidity, price volatility, ability to restructure loans, credit risks and less protective loan documentation. Fluctuations in the market price of securities may affect the value of the BSL’s investments and may increase the risks inherent in such investments. The ability to sell the investments in the market may depend on demand, which may be impracticable or impossible in certain market environments. Despite diversification, high concentration may arise in certain markets. Problems may be encountered in the valuation or sale of certain investments, and in some cases, investments may have to be sold below their value. Some investments may involve assets which are exposed to high market, credit and liquidity risks (including the risk of insolvency or bankruptcy of the borrower). Investments may be leveraged at the level of the investment (e.g., by margin borrowing or otherwise). If the capital gains on the investments acquired with leverage are greater than the interest on the loans, the investment’s assets will increase faster than if no leverage had been used. In the event of price falls, this leverage is outweighed by a more rapid decline in the investment’s assets.

 

Municipal Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Municipal Securities Risk. Municipal securities risks include the possibility that the issuer may be unable to pay interest or repay principal on a timely basis or at all, the relative lack of information about certain issuers of municipal securities, and the possibility of future legislative changes which could affect the market for and value of municipal securities. In addition, state or local political or economic conditions and developments can adversely affect the securities issued by state and local governments. The value of the municipal securities owned by the Fund also may be adversely affected by future changes in U.S. federal, state or local tax laws.

 

Municipal Securities Market Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Municipal Securities Market Liquidity Risk. From time to time, inventories of municipal securities held by brokers and dealers may decrease, lessening their ability to make a market in these securities. Any reduction in market making capacity has the potential to decrease the Fund’s ability to buy or sell municipal securities, and increase price volatility and trading costs, particularly during periods of economic or market stress. As a result, the Fund may be forced to accept a lower price to sell a municipal security, to sell other securities to raise cash, or to give up an investment opportunity, any of which could have a negative effect on performance.

 

Emerging Markets Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Emerging Markets Risks. Investments in emerging market issuers are subject to a greater risk of loss than investments in issuers located or operating in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, higher levels of inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments in emerging market countries than are typically found in more developed markets. Companies in many emerging markets are not subject to the same degree of regulatory requirements, recordkeeping requirements, accounting standards or auditor oversight as companies in more developed countries, and as a result, information about the securities in which the Fund invests may be less reliable or complete. Moreover, emerging markets often have less reliable securities valuations and greater risks associated with custody of securities than developed markets. There may be significant obstacles to obtaining information necessary for investigations into or litigation against companies and shareholders may have limited legal remedies. The Fund is not actively managed and does not select investments based on investor protection considerations. In addition, emerging markets often have greater risk of capital controls through such measures as taxes or interest rate control than developed markets. Certain emerging market countries may also lack the infrastructure necessary to attract large amounts of foreign trade and investment. Local securities markets in emerging market countries may trade a small number of securities and may be unable to respond effectively to changes in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times. Settlement procedures in emerging market countries are frequently less developed and reliable than those in the U.S. (and other developed countries). In addition, significant delays may occur in certain markets in registering the transfer of securities. There could be additional impacts on the value of the Fund as a result of sustainability risks, in particular those caused by environmental changes related to climate change, social issues (including relating to labor rights) and governance risk (including but not limited to risks around board independence, ownership and control, or audit and tax management). Additionally, disclosures or third-party data coverage associated with sustainability risks is generally less available or transparent in these markets.

 

Specifically, with respect to index funds, the conditions in emerging markets may lead to potential errors in index data, index computation, and/or index construction if information on non-U.S. companies is unreliable or outdated, or if less information about the non-U.S. companies is publicly available due to differences in regulatory, accounting, auditing and financial recordkeeping standards. This, in turn, may limit a fund adviser’s ability to oversee the index provider’s due diligence process over index data prior to its use in index computation, construction, and/or rebalancing. All of these factors may adversely impact fund performance. In addition, the rights and remedies associated with investments in a fund that tracks an index comprised of foreign securities may be different than a fund that tracks an index of domestic securities.

 

Tobeannounced Transactions Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

To-Be-Announced Transactions Risk. The Fund may be exposed to TBA transactions risk through the Fund’s investments in derivatives. TBA purchase commitments involve a risk of loss if the value of the securities to be purchased declines prior to the settlement date or if the counterparty does not deliver the securities as promised. Selling a TBA involves a risk of loss if the value of the securities to be sold goes up prior to settlement date. TBA transactions involve counterparty risk. Default or bankruptcy of a counterparty to a TBA transaction would expose the Fund to potential loss and could affect the Fund’s returns.

 

Sovereign And Quasisovereign Obligations Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Sovereign and Quasi-Sovereign Obligations Risk. The Fund invests in securities issued by or guaranteed by non-U.S. sovereign governments and by entities affiliated with or backed by non-U.S. sovereign governments, which may be unable or unwilling to repay principal or interest when due. Sovereign debt includes securities issued by or guaranteed by a foreign sovereign government, and quasi-sovereign debt includes securities issued by or guaranteed by an entity affiliated with or backed by a sovereign government. In times of economic uncertainty, the prices of these securities may be more volatile than those of corporate debt obligations or of other government debt obligations.

 

Non U S Agency Debt Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Non-U.S. Agency Debt Risk. The Fund invests in uncollateralized bonds issued by agencies, subdivisions or instrumentalities of foreign governments. Bonds issued by foreign government agencies, subdivisions or instrumentalities are generally backed only by the general creditworthiness and reputation of the entity issuing the bonds and may not be backed by the full faith and credit of the foreign government. Moreover, a foreign government that explicitly provides its full faith and credit to a particular entity may be, due to changed circumstances, unable or unwilling to provide that support. A non-U.S. agency’s operations and financial condition are influenced by the foreign government’s economic and other policies.

 

Non U S And Emerging Markets Debt Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Non-U.S. and Emerging Markets Debt Risk. The value of an investment in non-U.S. and emerging markets debt, even when U.S. dollar denominated, may be affected by political, economic, or social conditions. Non-U.S. and emerging markets debt may also be subject to risk of loss because of more or less foreign government regulation, less public information and less stringent investor protections and disclosure standards. Investing in emerging markets debt may involve more risk than investments in developed country debt.

 

Loan Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Loan Risk. An economic downturn generally leads to a higher non-payment rate, and a loan may lose significant value before a default occurs. Moreover, any specific collateral used to secure a loan may decline in value or become illiquid, which would adversely affect the loan’s value. No active trading market may exist for certain loans, which may impair the ability of the Fund to realize full value in the event of the need to sell a loan and which may make it difficult to value loans. Although loans in which the Fund will invest generally will be secured by specific collateral, there can be no assurance that liquidation of such collateral would satisfy the borrower’s obligation in the event of non-payment of scheduled interest or principal or that such collateral could be readily liquidated. To the extent that a loan is collateralized by stock in the borrower or its subsidiaries, such stock may lose all of its value in the event of the bankruptcy of the borrower. Uncollateralized senior loans involve a greater risk of loss.

 

Asset Class Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Asset Class Risk. Securities and other assets in the Index or in the Fund’s portfolio may underperform in comparison to the general financial markets, another index, a particular financial market or other asset classes.

 

Extension Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Extension Risk. During periods of rising interest rates, certain debt obligations will be paid off substantially more slowly than originally anticipated and the value of those securities may fall sharply, resulting in a decline in the Fund’s income and potentially in the value of the Fund’s investments.

 

Fixedtofloating Rate Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Fixed-to-Floating Rate Securities Risk. The Fund invests in fixed-to-floating rate securities, which are securities that have an initial term with a fixed dividend or coupon rate and following this initial term bear a floating rate. Securities which include a floating or variable interest rate component can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. Although floating rate securities can be less sensitive to interest rate risk than fixed-rate securities, they are subject to the risks applicable to hybrid and preferred securities more generally.

 

Variable And Floatingrate Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Variable and Floating-Rate Securities Risk. Variable and floating-rate securities pay interest at rates that are adjusted periodically, according to a specific formula. Because the interest rate is reset only periodically, changes in the interest rate on these securities may lag behind changes in the prevailing market interest rates. The value of the security may rise or fall depending on changes in interest rates between periodic resets.

 

Authorized Participant Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Authorized Participant Concentration Risk. An “Authorized Participant” is a member or participant of a clearing agency registered with the SEC, which has a written agreement with the Fund or one of its service providers that allows the Authorized Participant to place orders for the purchase and redemption of creation units (“Creation Units”). Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and Authorized Participants are not obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable or unwilling to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is willing or able to step forward to create or redeem, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

 

Large Shareholder And Largescale Redemption Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Large Shareholder and Large-Scale Redemption Risk. Certain shareholders, including an Authorized Participant, a third-party investor, the Fund’s adviser or an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own or manage a substantial amount of Fund shares, or may invest in the Fund and hold its investment for a limited period of time. There can be no assurance that any large shareholder or large group of shareholders would not redeem their investment. Redemptions of a large number of Fund shares could require the Fund to dispose of assets to meet the redemption requests, which can accelerate the realization of taxable income and/or capital gains and cause the Fund to make taxable distributions to its shareholders earlier than the Fund otherwise would have. In addition, under certain circumstances, non-redeeming shareholders may be treated as receiving a disproportionately large taxable distribution during or with respect to such year. These large redemptions may also force the Fund to sell portfolio securities when it might not otherwise do so, which may negatively impact the Fund’s NAV, increase the Fund’s brokerage costs and/or have a material effect on the market price of the Shares. In addition, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would, diluting its investment returns.

 

Call Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or repay the security prior to its stated maturity, and the Fund may have to reinvest the proceeds in securities with lower yields, which would result in a decline in the Fund’s income, or in securities with greater risks or with other less favorable features.

 

Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Concentration Risk. The Fund’s investments will generally follow the weightings of the Index, which may result in concentration of the Fund’s investments in a particular sovereign or quasi-sovereign entity or entities in a particular country, group of countries, region or market. To the extent that its investments are concentrated in a particular sovereign or quasi-sovereign entity or entities in a particular country, group of countries, region or market, the Fund may be more adversely affected by the underperformance of those bonds, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political, sustainability-related or regulatory occurrences affecting those securities and/or other assets than a fund that does not concentrate its investments.

 

Custody Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Custody Risk. Less developed securities markets are more likely to experience problems with the clearing and settling of trades, as well as the holding of securities by local banks, agents and depositories.

 

Cybersecurity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cybersecurity Risk. Failures or breaches of the electronic or computer systems of the Fund, BIM, the Fund’s distributor, the Index Provider and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Index Provider and other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

 

Geographic Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Geographic Risk. A natural disaster could occur in a geographic region in which the Fund invests, which could adversely affect the economy or the business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in, or which are exposed to, the affected region.

 

Illiquid Investments Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Illiquid Investments Risk. The Fund may invest up to an aggregate amount of 15% of its net assets in illiquid investments. An illiquid investment is any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without significantly changing the market value of the investment. To the extent the Fund holds illiquid investments, the illiquid investments may reduce the returns of the Fund because the Fund may be unable to transact at advantageous times or prices. During periods of market volatility, liquidity in the market for the Fund’s shares may be impacted by the liquidity in the market for the underlying securities or instruments held by the Fund, which could lead to the Fund’s shares trading at a premium or discount to the Fund’s NAV.

 

Income Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Income Risk. The Fund’s income may decline if interest rates fall. This decline in income can occur because the Fund may subsequently invest in lower- yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Index are substituted, or the Fund otherwise needs to purchase additional bonds.

 

Indexrelated Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Index-Related Risk. There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Index or that the Fund will achieve its investment objective. Indexing will eliminate the chance that the Fund will substantially outperform the Index but also may reduce some of the risks of active management, such as poor security selection. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Index. Errors in index data, index computations or the construction of the Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party data provider, and could cause the Index Provider to postpone a scheduled rebalance. This could cause the Index to vary from its normal or expected composition. In addition, the Index Provider may be subject to business or regulatory changes that impair its ability to continue to operate the Index in its current form.

 

Inflation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Inflation Risk. Inflation is a sustained rise in overall price levels. Moderate inflation is associated with economic growth, while high inflation can signal an overheated economy. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money (i.e., as inflation increases, the values of the Fund’s assets can decline). Inflation poses a “stealth” threat to investors because it reduces savings and investment returns. Central banks, such as the U.S. Federal Reserve, generally attempt to control inflation by regulating the pace of economic activity. They typically attempt to affect economic activity by raising and lowering short-term interest rates. At times, governments may attempt to manage inflation through fiscal policy, such as by raising taxes or reducing spending, thereby reducing economic activity; conversely, governments can attempt to combat deflation with tax cuts and increased spending designed to stimulate economic activity. Inflation rates may change frequently and significantly as a result of various factors, including unexpected shifts in the domestic or global economy and changes in economic policies, and the Fund’s investments may not keep pace with inflation, which may result in losses to Fund shareholders. This risk is greater for fixed-income instruments with longer maturities.

 

Securities Lending Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

 

Issuer Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. The Fund may be adversely affected if an issuer of underlying securities held by the Fund is unable or unwilling to repay principal or interest when due. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

 

Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Management Risk. Because BIM and the Sub-Adviser each use a representative sampling indexing strategy, the Fund may not be able to fully replicate the Index and may hold securities not included in the Index. As a result, the Fund is subject to the risk that BIM’s and the Sub-Adviser’s investment strategies, the implementation of which are subject to a number of constraints, may not produce the intended results. See also “Management—Manager of Managers Structure.”

 

Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. Market risk includes the risk that geopolitical and other events will disrupt the economy on a national or global level. For instance, actual or threatened events such as war, acts of terrorism, social unrest, supply chain disruptions, the spread of infectious illness or other public health issues, recessions, the advent of significant inflation, imposition of sanctions and other similar measures, including the imposition of tariffs, or other U.S. economic policies, or other events could have a significant impact on the Fund and its investments and could result in increased premiums or discounts to the Fund’s NAV.

 

Market Trading Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares or the Fund’s underlying portfolio securities, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. Accordingly, if a shareholder purchases Fund shares at a time when the market price is at a premium to the NAV, or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

 

National Closed Market Trading Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

National Closed Market Trading Risk. To the extent that securities or other assets held by the Fund trade on foreign exchanges or in foreign markets that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between such asset’s current price and its last quoted price (i.e., the quote from the closed foreign market to the Fund). The impact of a closed foreign market on the Fund is likely to be greater where a large portion of the Fund’s holdings trade on a closed foreign market or when a foreign market is closed for unscheduled reasons. These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other funds.

Risk [Text Block]

Non-Diversification Risk. The Fund is classified as a “non-diversified” fund under the Investment Company Act of 1940, as amended (the “1940 Act”). Accordingly, the Fund may invest a greater portion of its assets in the securities of a single issuer than if it were a “diversified” fund. To the extent that the Fund invests a higher percentage of its assets in the securities of a single issuer, the Fund is subject to a higher degree of risk associated with and developments affecting that issuer than a fund that invests more widely.

 

Non U S Issuers Risk [Member]

Risk [Text Block]

Non-U.S. Issuers Risk. Securities issued by non-U.S. issuers have different risks from securities issued by U.S. issuers. These risks include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, restrictions or limitations on trade, including export controls and tariffs, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in non-U.S. countries, uncertainties of transnational litigation, regulatory and economic differences, and potential restrictions on the flow of international capital, including the possible seizure or nationalization of the securities issued by non-U.S. issuers held by the Fund. Non-U.S. issuers may be subject to less governmental regulation than U.S. issuers. Moreover, individual non-U.S. economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rate of inflation, capital reinvestment, resource self-sufficiency and balance of payment positions. Unfavorable political, economic or governmental developments in non-U.S. countries could affect the payment of a security’s principal and interest. Securities issued by non-U.S. issuers may also be less liquid than, and more difficult to value than, securities of U.S. issuers. In addition, the value of these securities may fluctuate due to changes in the exchange rate of the issuer’s local currency against the U.S. dollar.

Risk [Text Block]

U.S. Economic Risk. Investing in U.S. issuers subjects the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to the U.S. Certain changes in the U.S., such as a weakening of the U.S. economy or a decline in its financial markets, may have an adverse effect on U.S. issuers. The U.S. is also a significant trading partner of and in some cases the most significant, trading partner of, or foreign investor in, certain country or countries in which the Fund invests. As a result, economic conditions of such countries may be particularly affected by changes in the U.S. economy.

 

Operational And Information Security Risk [Member]

Risk [Text Block]

Operational and Information Security Risk. An investment in the Fund, like any fund, can involve operational risks arising from factors such as processing errors, human errors, inadequate or failed internal or external processes, failures in systems and technology, changes in personnel and errors caused by third-party service providers. The rapid development and increasingly widespread use of artificial intelligence in the financial services industry, including machine learning technology and generative artificial intelligence such as ChatGPT, could exacerbate these risks. The occurrence of any of these failures, errors or breaches could result in investment losses to the Fund, a loss of information, regulatory scrutiny, reputational damage or other events, any of which could have a material adverse effect on the Fund. While the Fund and BIM seek to minimize such events through controls and oversight, there may still be failures that could cause losses to the Fund.

Risk [Text Block]

Reliance on Trading Partners Risk. The economies of many countries or regions in which the Fund invests are highly dependent on trade with certain key trading partners. Reduction in spending on products and services by these key trading partners, institution of tariffs or other trade barriers or a slowdown in the economies of key trading partners may adversely affect the performance of any company in which the Fund invests and have a material adverse effect on the Fund’s performance.

 

Security Risk [Member]

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns, such as terrorism and strained international relations. Incidents involving a country’s or region’s security may cause uncertainty in its markets and may adversely affect its economy and the Fund’s investments.

 

Tracking Error Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tracking Error Risk. The Fund may be subject to tracking error, which is the divergence of the Fund’s performance from that of the Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund’s valuation of a security at the time of calculation of the Fund’s NAV or differences between the securities prices used to value the Index and those used by the Fund), transaction costs incurred by the Fund, securities lending earnings, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain qualification for treatment as a regulated investment company (“RIC”) for U.S. federal income tax purposes, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Index or the costs to the Fund of complying with various new or existing regulatory requirements, among other reasons. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not. INDEX ETFs THAT TRACK INDICES WITH SIGNIFICANT WEIGHT IN EMERGING MARKETS ISSUERS MAY EXPERIENCE HIGHER TRACKING ERROR THAN OTHER ETFs THAT DO NOT TRACK SUCH INDICES.

 

Valuation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund’s valuation of the security or other asset and from the value used by the Index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. Because non-U.S. stock exchanges may be open on days when the Fund does not price its shares, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by a lack of current market prices, technological issues or errors by pricing services or other third-party service providers.

 

Exchangetraded Fund And Other Registered Investment Company Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Exchange-Traded Fund and Other Registered Investment Company Risk. The Fund may invest in shares of other registered investment companies and ETFs. Shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of the underlying investment company or ETF when the Fund invests in shares of another registered investment company or ETF. The Fund is subject to the risks associated with the ETF or investment company’s investments. The price and movement of an ETF designed to track an index may not track the index and may result in a loss. In addition, ETFs may trade at a price above (premium) or below (discount) their net asset value, especially during periods of significant market volatility or stress, causing investors to pay significantly more or less than the value of the ETF’s underlying portfolio. Certain ETFs traded on exchanges may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer.
