Below Investment Grade Securities Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Below-Investment Grade Securities Risk. The Trust may invest in Income Securities (as defined below) rated below-investment grade or, if unrated, determined by GPIM to be of comparable credit quality, which are commonly referred to as “high-yield” or “junk” bonds. Investment in securities of below-investment grade quality involves substantial risk of loss and increased volatility, the risk of which is particularly acute under adverse market or economic conditions. Income Securities of below-investment grade quality are predominantly speculative with respect to the issuer’s continuing capacity to pay interest and repay principal when due and therefore involve additional and heightened risks compared to investment grade bonds, including a greater risk of default or decline in market

value or income due to adverse economic and issuer-specific developments, such as financial condition, operating results and outlook and real or perceived adverse economic and competitive industry conditions. Accordingly, the performance of the Trust and a shareholder’s investment in the Trust may be adversely affected if an issuer is unable to pay interest and repay principal, either on time or at all. Issuers of below-investment grade securities are not perceived to be as strong financially as those with higher credit ratings. Securities of below-investment grade quality may experience greater price volatility than higher-rated securities of similar maturity. Generally, the risks associated with below-investment grade securities are heightened during times of weakening economic conditions or rising interest rates (particularly for issuers that are highly leveraged).

Build America Bonds Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Build America Bonds (“BABs”) Risk. BABs were an alternative form of financing to state and local governments whose primary means for accessing the capital markets had been through issuance of tax-free municipal bonds. The BABs market is smaller and less diverse than the broader municipal securities market. In addition, because the relevant provisions of the American Recovery and Reinvestment Act of 2009 were not extended, bonds issued after December 31, 2010 cannot qualify as BABs. It is uncertain whether Congress will renew the program to permit issuance of new Build America Bonds. As a result, the number of available BABs is limited, which may negatively affect the value of BABs. In addition, there can be no assurance that BABs will continue to be actively traded. It is difficult to predict the extent to which a market for such bonds will continue, meaning that BABs may experience greater illiquidity than other municipal obligations.
Corporate Bond Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Corporate Bond Risk. Corporate bonds are debt obligations issued by corporations and other business entities. Corporate bonds may be either secured or unsecured. Corporate bonds contain elements of both interest-rate risk and credit risk and are subject to the risks associated with other debt securities, among other risks. The market value of a corporate bond generally is expected to rise and fall inversely with interest rates. The market value of a corporate bond is affected by factors directly related to the issuer, such as its credit rating, investors’ perceptions of the creditworthiness of the issuer, the issuer’s financial condition and performance, perceptions of the issuer in the marketplace, performance of management of the issuer, the issuer’s capital structure and use of financial leverage and demand for the issuer’s goods and services, as well as general market and economic conditions. There is a risk that the issuers of corporate bonds may not be able to meet their obligations on interest or principal payments at the time called for by an instrument or at all. Depending on the nature of the seniority provisions, a senior corporate bond may be junior to other credit securities of the issuer, which increases risks associated with the bond. Corporate bonds of below-investment grade quality are often high risk and have speculative characteristics and may be particularly susceptible to adverse issuer-specific and other developments.
Credit Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Credit Risk. The Trust could lose money if the issuer or guarantor of a debt instrument, a counterparty to a derivatives transaction or other transaction (such as a repurchase agreement or a loan of portfolio securities or other instruments) or other obligor to the Trust is unable or unwilling, or perceived (whether by market participants, rating agencies, pricing services or otherwise) to be

unable or unwilling, to pay interest or repay principal on time or defaults or otherwise fails to meet obligations. This risk is heightened during adverse economic conditions and in market environments where interest rates are changing, notably when rates are rising or when refinancing obligations becomes more challenging. Also, the issuer, guarantor or counterparty may suffer adverse changes in its financial condition, the value of its assets, prospective earnings, demands for its goods and services or be adversely affected by economic, political or social conditions that could lower the financial condition or credit quality (or the market’s perception of the financial condition or credit quality) of the issuer, instrument, guarantor or counterparty, leading to greater volatility in the price of the instrument and in shares of the Trust. Although credit quality may not accurately reflect the true credit risk of an instrument, credit quality (and credit risks) are subject to change and a change in the credit quality rating of an instrument or an issuer can have a rapid, adverse effect on the instrument’s value, price volatility and liquidity and make it more difficult for the Trust to sell at an advantageous price or time. The risk of the occurrence of these types of events is heightened in market environments where interest rates are changing, notably when rates are rising. High yield or below-investment grade securities are particularly subject to credit risk.

Current Fixed Income And Debt Market Conditions [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Current Fixed-Income and Debt Market Conditions. Fixed-income and debt market conditions are highly unpredictable and some parts of the market are subject to dislocations. In response to market and economic conditions, such as the inflation rates in recent periods, governmental authorities may implement significant fiscal and monetary policy changes, including changing interest rates and implementation of quantitative tightening or easing. These and other fiscal and monetary policy actions present heightened risks, particularly to fixed-income and debt instruments, and such risks could be even further heightened if these actions are ineffective in achieving their desired outcomes or are quickly reversed. It is difficult to accurately predict changes in the U.S. Federal Reserve Board’s (“Federal Reserve”) monetary policies and the effect of any such changes or policies. Certain economic conditions and market environments will expose fixed-income and debt instruments to heightened volatility and reduced liquidity, which can impact the Trust’s investments and may negatively impact the Trust’s characteristics, which in turn would impact performance.
Debt Instruments Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Debt Instruments Risk. The value of the Trust’s investments in debt instruments (including bonds issued by non-profit entities, municipal conduits and project finance corporations) depends on the continuing ability of the debt issuers to meet their obligations for the payment of interest and principal when due. The ability of debt issuers to make timely payments of interest and principal can be affected by a variety of developments and changes in legal, political, market, economic and other conditions. Investments in debt instruments present certain risks, including credit, interest rate, liquidity and prepayment and extension risks and may include risks associated with below-investment grade investments. Issuers that rely directly or indirectly on government funding mechanisms or non-profit statutes, may be negatively affected by actions of the government, including reductions in government spending or support, increases in tax rates, and changes in fiscal policy. The value of a debt instrument may decline for many reasons that directly relate to the issuer, such as a change in

the demand for the issuer’s goods or services, or a decline in the issuer’s performance, earnings or assets. In addition, changes in the financial condition of an individual issuer can affect the value and overall market for such instruments. The risk of the occurrence of these types of unfavorable events is heightened in market environments where interest rates are changing, notably when they are rising. The income generated by debt instruments can also be adversely affected as a result of the occurrence of these types of events or conditions.

Investment And Market Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Investment and Market Risk. An investment in the common shares is subject to investment risk, including the possible loss of the entire principal amount that you invest. During periods of adverse economic, financial, market, geopolitical, labor and public health conditions, the risks associated with an investment in common shares may be heightened. An investment in the common shares represents an indirect investment in the securities and other assets owned by the Trust. The value of, or income generated by, the investments held by the Trust are subject to the possibility of frequent, significant, rapid and/or unpredictable fluctuation and loss. The value of certain investments (e.g., equity securities) tends to fluctuate more dramatically over the shorter term than do the values of other asset classes. These movements may result from factors affecting (or perceived to affect) individual companies or issuers or particular industries, or from broader influences, including real or perceived changes in prevailing interest rates, changes in inflation rates or expectations about inflation rates, adverse investor confidence or sentiment, general outlook for corporate earnings, changing economic, political (including geopolitical), social or financial market conditions, bank failures, the actual or threatened imposition of tariffs and trade disruptions, recession, changes in

currency rates, increased instability or general uncertainty, environmental, natural or other disasters, extreme weather or geological events, governmental or quasi-governmental actions, cyber attacks, public health emergencies (such as the spread of infectious diseases, pandemics and epidemics), debt crises, terrorism, actual or threatened wars or other armed conflicts (such as the escalated conflict in the Middle East and the ongoing Russia-Ukraine conflict and the risk of expansion or collateral economic and other effects) or ratings downgrades, and other similar types of events, each of which may be temporary or last for extended periods.

Many economies and markets may experience, and have experienced in recent periods, high inflation rates. In response to such inflation and other economic conditions, governmental and quasi-governmental authorities have implemented significant fiscal and monetary policies such as changing interest rates and quantitative tightening (reduction of money available in the market), and could take these or other measures in the future. Such interventions (or their reversal) may not be effective and could lead to increased market volatility and adverse economic conditions, which could negatively impact the Trust’s performance.

Administrative changes, policy reform and/or changes in law or governmental regulations can result in expropriation or nationalization of the investments of a company in which the Trust invests. In addition, adverse changes in one sector or industry or with respect to a particular company could negatively impact companies in other sectors or industries or increase market volatility as a result of the interconnected nature of economies and markets and thus negatively affect the Trust’s performance. For example, developments in the banking or financial services sectors (or one or more companies operating in these sectors) could adversely impact a wide range of companies and issuers. These types of adverse developments could negatively affect the Trust’s performance or operations.

Different sectors, industries and security types may react differently to such developments and, when the market performs well, there is no assurance that the Trust’s investments will increase in value along with the broader markets and the Trust’s investments may underperform general securities markets or other investments. Volatility of financial markets, including potentially extreme volatility caused by the events described above or other events, can expose the Trust to greater market risk than normal, possibly resulting in greatly reduced liquidity, increased volatility and valuation risks and longer than usual trade settlement periods. Moreover, changing economic, political, social, geopolitical, financial market, or other conditions in one country or geographic region could adversely affect the value, yield and return of the investments held by the Trust in a different country or geographic region because of the increasingly interconnected global economies and financial markets.

At any point in time, your common shares may be worth less than your original investment, even after including the reinvestment of Trust dividends and distributions.

Investment Funds Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Investment Funds Risk. As an alternative to holding investments directly, the Trust may also obtain investment exposure to securities in which it may invest directly by investing in other investment companies, including U.S. registered investment companies and/or other U.S. or foreign pooled investment vehicles (collectively, “Investment Funds”). Investments in Investment Funds present certain special considerations and risks not present in making direct investments in securities in which the Trust may invest. Investments in Investment Funds subject the Trust to the risks affecting such Investment Funds and involve operating expenses and fees that are in addition to the expenses and fees borne by the Trust. Such expenses and fees attributable to the Trust’s investment in another Investment Fund are borne indirectly by common shareholders. Accordingly, investment in such entities involves expenses and fees at both levels. To the extent management fees of Investment Funds are based on total gross assets, it may create an incentive for such entities’ managers to employ financial leverage, thereby adding additional expense and increasing volatility and risk (including the Trust’s overall exposure to leverage risk). A performance-based fee arrangement may create incentives for an adviser or manager to take greater investment risks in the hope of earning a higher profit participation. Investments in Investment Funds frequently expose the Trust to an additional layer of financial leverage and, thus, increase the Trust’s exposure to leverage risk and costs. From time to time, the Trust may invest a significant portion of its assets in Investment Funds that employ leverage. The use of leverage by Investment Funds may cause these Investment Funds’ market price of common shares and/or NAV to be more volatile and can magnify the effect of any losses and cause similar effects on the Trust.
Investment In Loans Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Investment in Loans Risk. The Trust may purchase loans on a direct assignment basis from a participant in the original syndicate of lenders or from subsequent assignees of such interests. Loans may offer a fixed or floating interest rate. Loans are often below-investment grade and may be unrated. The Trust’s investments in loans can also be difficult to value accurately because of, among other factors, limited public information regarding the loans or the borrowers and may be more susceptible to liquidity risk than fixed income instruments of similar credit quality and/or maturity. Risks associated with investments in loans are increased if the loans are secured by a single asset. Loans may decline in value if their interest rates do not rise as much or as fast as interest rates in general. Participations in loans may subject the Trust to the credit risk of both the borrower and the seller of the participation and may make enforcement of loan covenants, if any, more difficult for the Trust as legal action may have to go through the seller of the participation (or an agent acting on its behalf). Covenants contained in loan documentation are intended to protect lenders and investors by imposing certain restrictions and other limitations on a borrower’s operations or assets and by providing certain information and consent rights to lenders.
Senior Loans Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Senior Loans Risk. The Trust may invest in senior secured floating rate loans made to corporations and other non-governmental entities and issuers (“Senior Loans”). Senior Loans typically hold the most senior position in the capital structure of the issuing entity, are typically secured with specific collateral and typically have a claim on the assets of the borrower, including stock owned by the

borrower in its subsidiaries, that is senior to that held by junior lien creditors, subordinated debt holders and stockholders of the borrower. The Trust’s investments in Senior Loans are typically below-investment grade and are considered speculative because of the credit risk of the applicable issuer. The risks associated with Senior Loans of below-investment grade quality are similar to the risks of other lower grade securities, although Senior Loans are typically senior in payment priority and secured on a senior priority basis in contrast to subordinated and unsecured securities. An investment in Senior Loans involves the risk that the borrowers under Senior Loans may default on their obligations to pay principal and/or interest when due. In the event a borrower fails to pay scheduled interest or principal payments on a Senior Loan held by the Trust, the Trust will experience a reduction in its income and a decline in the market value of the Senior Loan, which will likely reduce dividends and lead to a decline in the Trust’s NAV.

There is less readily-available, reliable information about most Senior Loans than is the case for many other types of securities. In addition, there is rarely a minimum rating or other independent evaluation of a borrower or its securities, and GPIM relies primarily on its own evaluation of a borrower’s credit quality rather than on any available independent sources. As a result, the Trust is particularly dependent on the analytical abilities of GPIM with respect to investments in Senior Loans. GPIM’s judgment about the credit quality of a borrower may be wrong. Loans and other debt instruments are also subject to the risk of price declines due to increases in prevailing interest rates, although floating-rate debt instruments are less exposed to this risk than fixed-rate debt instruments. Interest rate changes may also increase prepayments of debt obligations and require the Trust to invest assets at lower yields, particularly during periods of declining rates. In addition, extension risk (the risk that payments on principal will occur at a slower rate or later than expected) is heightened in market environments where interest rates are higher or rising. During periods of deteriorating economic conditions, such as recessions or periods of rising unemployment, or changing interest rates (notably increases), delinquencies and losses generally increase, sometimes dramatically, with respect to obligations under such loans. An economic downturn or individual corporate developments could adversely affect the value and market for these instruments and reduce the Trust’s ability to sell these instruments at an advantageous time or price. An economic downturn would generally lead to a higher non-payment rate, and a Senior Loan may lose significant market value before a default occurs.

Second Lien Loans Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Second Lien Loans Risk. The Trust may invest in “second lien” secured floating rate loans made by public and private corporations and other non-governmental entities and issuers for a variety of purposes (“Second Lien Loans”). Second Lien Loans are typically second in right of payment and/ or second in right of priority with respect to collateral remedies to one or more Senior Loans of the related borrower. Second Lien Loans are subject to the same risks associated with investment in Senior Loans and other lower grade Income Securities. However, Second Lien Loans are second in right of payment and/or second in right of priority with respect to collateral remedies to Senior Loans and therefore are subject to the additional risk that the cash flow of the borrower and/or the value of any property securing the Loan may be insufficient to meet scheduled payments or

otherwise be available to repay the Loan after giving effect to payments in respect of a Senior Loan, including payments made with the proceeds of any property securing the Loan and any senior secured obligations of the borrower. Second Lien Loans are expected to have greater price volatility and exposure to losses upon default than Senior Loans and may be less liquid. There is also a possibility that originators will not be able to sell participations in Second Lien Loans, which would create greater credit risk exposure.

Subordinated Secured Loans Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Subordinated Secured Loans Risk. Subordinated secured loans generally are subject to similar risks as those associated with investment in Senior Loans, Second Lien Loans and below-investment grade securities. However, such loans may rank lower in right of payment than any outstanding Senior Loans, Second Lien Loans or other debt instruments with higher priority of the borrower and therefore are subject to additional risk that the cash flow of the borrower and any property securing the loan may be insufficient to meet scheduled payments and repayment of principal in the event of default or bankruptcy after giving effect to the higher ranking secured obligations of the borrower. Subordinated secured loans are expected to have greater price volatility than Senior Loans and Second Lien Loans and may be less liquid.
Unsecured Loans Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Unsecured Loans Risk. Unsecured loans generally are subject to similar risks as those associated with investment in Senior Loans, Second Lien Loans, subordinated secured loans and below-investment grade securities. However, because unsecured loans have lower priority in right of payment to any higher ranking obligations of the borrower and are not backed by a security interest in any specific collateral, they are subject to additional risk that the cash flow of the borrower and available assets may be insufficient to meet scheduled payments and repayment of principal after giving effect to any higher ranking obligations of the borrower. Unsecured loans are expected to have greater price volatility than Senior Loans, Second Lien Loans and subordinated secured loans and may be less liquid.
Loans And Loan Particiaptions And Assignment Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Loans and Loan Participations and Assignments Risk. The Trust may invest in loans directly or through participations or assignments. The Trust may purchase loans on a direct assignment basis from a participant in the original syndicate of lenders or from subsequent assignees of such interests. The Trust may also purchase, without limitation, participations in loans. The purchaser of an assignment typically succeeds to all the rights and obligations of the assigning institution and becomes a lender under the credit agreement with respect to the debt obligation; however, the purchaser’s rights can be more restricted than those of the assigning institution, and, in any event, the Trust may not be able to unilaterally enforce all rights and remedies under the loan and with regard to any associated collateral. The Trust’s interest in a particular loan and/or in particular collateral securing a loan may be subordinate to the interests of other creditors of the obligor, which leads to the risk of subordination to other creditors. A participation typically results in a contractual relationship only with the institution participating out the interest, not with the borrower. In purchasing participations, the Trust generally will have no right to enforce compliance by the borrower with the terms of the loan agreement against the borrower, and the Trust may not directly benefit from the collateral supporting

the debt obligation in which it has purchased the participation. As a result, the Trust will be exposed to the credit risk of both the borrower and the institution selling the participation. Further, in purchasing participations in lending syndicates, the Trust may not be able to conduct the same due diligence on the borrower with respect to a Senior Loan that the Trust would otherwise conduct. In addition, as a holder of the participations, the Trust may not have voting rights or inspection rights that the Trust would otherwise have if it were investing directly in the loan, which may result in the Trust being exposed to greater credit or fraud risk with respect to the borrower or the loan. Lenders selling a participation and other persons inter-positioned between the lender and the Trust with respect to a participation will likely conduct their principal business activities in the banking, finance and financial services industries. Because the Trust may invest in participations, the Trust may be more susceptible to economic, political or regulatory occurrences affecting such industries.

Loans are especially vulnerable to the financial health, or perceived financial health, of the borrower but are also particularly susceptible to economic and market sentiment such that changes in these conditions or the occurrence of other economic or market events may reduce the demand for loans, increase the risks associated with such investments and cause their value to decline rapidly and unpredictably. Many loans and loan interests are subject to legal or contractual restrictions on transfer, resale or assignment that may limit the ability of the Trust to sell its interest in a loan at an advantageous time or price. Transactions in loans are often subject to long settlement periods. The Trust thus is subject to the risk of selling other investments at disadvantageous times or prices or taking other actions necessary to raise cash to meet its obligations such as borrowing from a bank or holding additional cash, particularly during periods of unusual market or economic conditions or financial stress. Investments in loans can also be difficult to value accurately because of, among other factors, limited public information regarding the loans or the borrowers. Risks associated with investments in loans are increased if the loans are secured by a single asset. Loans may offer a fixed rate or floating rate of interest. Loans may decline in value if their interest rates do not rise as much or as fast as interest rates in general. For example, the interest rates on floating rate loans typically adjust only periodically and therefore the interest rate payable under such loans may significantly trail market interest rates.

The Trust invests in or is exposed to loans and other similar debt obligations that are sometimes referred to as “covenant-lite” loans or obligations (“covenant-lite obligations”), which are loans or other similar debt obligations that lack financial maintenance covenants or possess fewer or contingent financial maintenance covenants and other financial protections for lenders and investors. Exposure may also be obtained to covenant-lite obligations through investment in securitization vehicles and other structured products. Covenant-lite obligations may carry more risk than traditional loans as they allow borrowers to engage in activities that would otherwise be difficult or impossible under an agreement that is not covenant-lite. The Trust may have fewer rights with respect to covenant-lite obligations, including fewer protections against the possibility of default and fewer remedies in the event of default as the lender may not have the opportunity to negotiate with the

borrower prior to default. As a result, investments in (or exposure to) covenant-lite obligations are subject to more risk than investments in (or exposure to) certain other types of obligations. In the event of default, covenant-lite obligations may exhibit diminished recovery values as the lender may not have the opportunity to negotiate with the borrower prior to default. In addition, the Trust may receive less or less frequent financial reporting from a borrower under a covenant-lite obligation, which may result in more limited access to financial information, difficulty evaluating the borrower’s financial performance over time and delays in exercising rights and remedies in the event of a significant financial decline.

The Trust is subject to other risks associated with investments in (or exposure to) Loans and other similar obligations, including that such Loans or obligations may not be considered “securities” under federal securities laws and, as a result, the Trust may not be entitled to rely on the anti-fraud protections under the federal securities laws and instead may have to resort to state law and direct claims.

Mezzanine Investments Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Mezzanine Investments Risk. The Trust may invest in certain lower grade securities known as “Mezzanine Investments,” which are subordinated debt securities that are generally issued in private placements in connection with an equity security (e.g., with attached warrants) or may be convertible into equity securities. Mezzanine Investments are subject to the same risks associated with investment in Senior Loans, Second Lien Loans and other lower grade Income Securities. However, Mezzanine Investments may rank lower in right of payment than any outstanding Senior Loans and Second Lien Loans of the borrower, or may be unsecured (i.e., not backed by a security interest in any specific collateral), and are subject to the additional risk that the cash flow of the borrower and available assets may be insufficient to meet scheduled payments after giving effect to any higher-ranking obligations of the borrower. Mezzanine Investments are expected to have greater price volatility and exposure to losses upon default than Senior Loans and Second Lien Loans and may be less liquid.
Leverage Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Leverage Risk. The Trust’s use of leverage, through borrowings or instruments such as derivatives, causes the Trust to be more volatile and riskier than if it had not been leveraged. Although the use of leverage by the Trust may create an opportunity for increased return, it also results in additional risks and can magnify the effect of any losses and may be subject to increased borrowing rates. The effect of leverage in a declining market is likely to cause a greater decline in the net asset value of the Trust than if the Trust were not leveraged, which may result in a greater decline in the market price of the Trust shares. There can be no assurance that a leveraging strategy will be implemented or that it will be successful during any period during which it is employed. When the cost of leverage is no longer favorable, or when the Trust is otherwise required to reduce its leverage, the Trust may not be able to maintain distributions at historical levels and common shareholders will bear any costs associated with selling portfolio securities. The Trust’s total leverage, and associated borrowing costs, may vary significantly over time. To the extent the Trust increases its amount of leverage outstanding, it will be more exposed to these risks and pay greater borrowing costs. Investments in Investment Funds

and certain other pooled and structured finance vehicles, such as collateralized loan obligations, frequently expose the Fund to an additional layer of financial leverage and, thus, increase the Trust’s exposure to leverage risk.

Liquidity Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Liquidity Risk. The Trust may invest in municipal securities and other investments that are, at the time of investment, illiquid or become illiquid. Illiquid investments are securities that cannot be disposed of within seven days in the ordinary course of business at approximately the value that the Trust values the securities. Illiquid investments may trade at a discount from comparable, more liquid securities and may be subject to wide fluctuations in market value. The Trust may be subject to significant delays in disposing of illiquid investments. Accordingly, the Trust may be forced to sell these investments at less than fair market value or may not be able to sell them when GPIM believes it is desirable to do so. If the Trust is unable to sell an investment at its desired time, the Trust may miss other investment opportunities while it holds investments it would prefer to sell, which could adversely affect the Trust’s performance. Illiquid investments also may entail registration expenses and other transaction costs that are higher than those for liquid investments. Dislocations or unfavorable conditions in certain parts of markets may result in reduced liquidity for certain investments. Liquidity of financial markets may also be affected by government intervention, such as the legal restrictions on certain financial instruments’ resale. In addition, the liquidity of any Trust investment may change significantly as a result of market, economic, trading, issuer-specific and other factors.
Management Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Management Risk. The Trust is subject to management risk because it has an actively managed portfolio. GPIM will apply investment techniques and risk analysis in making investment decisions for the Trust, but there can be no guarantee that these will produce the desired results or expected returns, causing the Trust to fail to meet its investment objective or underperform its benchmark index or funds with similar investment objectives and strategies. The Trust’s allocation of its investments across various asset classes and sectors may vary significantly over time based on GPIM’s analysis and judgment. As a result, the particular risks most relevant to an investment in the Trust, as well as the overall risk profile of the Trust’s portfolio, may vary over time. The ability of the Trust to achieve its investment objective depends, in part, on GPIM’s investment decisions and the ability of GPIM to allocate effectively the Trust’s assets among multiple investment strategies, underlying funds and investments and asset classes. Although GPIM considers several factors when making investment decisions, GPIM may not evaluate every factor prior to investing in an issuer or security or disposing of an investment, and GPIM may determine that certain factors are more significant than others. There can be no assurance that the actual allocations will be effective in achieving the Trust’s investment objective or that an investment strategy or underlying fund or investment will achieve its particular investment objective.
Municipal Conduit Bond Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Municipal Conduit Bond Risk. Municipal conduit bonds, also referred to as private activity bonds or industrial revenue bonds, are bonds issued by state and local governments or other entities for the purpose of financing the projects of certain private enterprises. Unlike municipal bonds, municipal conduit bonds are not backed by the full faith, credit or general taxing power of the issuing

governmental entity. Rather, issuances of municipal conduit bonds are backed solely by revenues of the private enterprise involved. Therefore, in addition to being subject to the general risks associated with municipal securities, municipal conduit bonds are subject to heightened credit risk, as the private enterprise involved can have a different credit profile than the issuing governmental entity. Municipal conduit bonds may be negatively impacted by conditions affecting either the general credit of the private enterprise or the project itself. Factors such as competitive pricing, construction delays, or lack of demand for or use of the project could cause project revenues to fall short of projections, and defaults could occur. Municipal conduit bonds tend to have longer terms and thus are more susceptible to interest rate risk.

Municipal Securities Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Municipal Securities Risk. The Trust’s holdings of municipal securities could be significantly affected by events that affect the municipal bond market, which could include unfavorable legislative, tax, political or other developments, adverse changes in the financial conditions of issuers of municipal securities, or other actual or perceived changes in economic, social, or public health conditions. The amount of public information available about municipal securities is generally less than that for corporate equities or bonds. The secondary market for municipal securities also tends to be less well-developed or liquid than many other securities markets, which may adversely affect the Trust’s ability to sell such securities at prices approximating those at which the Trust may currently value them. In addition, municipal securities are subject to credit and interest rate risks and state and municipal governments that issue such securities are subject to experiencing significant economic and financial stress and may not be able to satisfy their obligations. Issuers of municipal securities might seek protection under bankruptcy laws. In the event of bankruptcy of such an issuer, holders of municipal securities could experience delays in collecting principal and interest and such holders may not be able to collect all principal and interest to which they are entitled. Legislative developments may result in changes to the laws relating to municipal bankruptcies. The income, value and/or risk of municipal securities is often correlated to specific project or other revenue sources, which may be insufficient to satisfy the obligations. Municipal securities can be negatively affected by demographic trends, such as population shifts or changing tastes and values, or increasing vacancies or declining rents or property values resulting from legal, cultural, technological, global or local economic developments, as well as reduced demand for properties, revenues, goods or services. Municipalities and municipal projects that rely directly or indirectly on federal funding mechanisms may be negatively affected by constraints of the federal government budget. Each of the foregoing may adversely affect the Trust’s investments in municipal securities. To the extent that the Trust invests a significant portion of its assets in securities or other obligations of particular municipalities or states, the Trust will be more sensitive to adverse economic, business or political developments affecting such municipalities or states.
Project Finance Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Project Finance Risk. Project finance is a type of financing commonly used for infrastructure, industry, and public service projects. In a project finance arrangement, the cash flow generated by the project is used to repay lenders while the project’s assets, rights and interest are held as secondary collateral. Investors involved in project finance face heightened technology risk, operational risk, and market risk

because the cash flow generated by the project, rather than the revenues of the company behind the project, will repay investors. In addition, because of the project-specific nature of such arrangements, the Trust face the risk of loss of investment if the company behind the project determines not to complete it. To the extent that the Trust invests a significant portion of its assets in securities that finance similar projects, such as those relating to education or schools, healthcare or hospitals, housing, utilities, or water and sewers, the Trust will be more sensitive to adverse economic, business or political developments affecting such particular project or similar projects, such as economic, political and business conditions.

Debts Issued By Non Profits Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Risks of Investing in Debt Issued by Non-Profit Institutions. Investing in debt issued by non-profit institutions, including foundations, museums, cultural institutions, colleges, universities, hospitals and healthcare systems, involves different risks than investing in municipal bonds. Many non-profit entities are tax-exempt under Section 501(c)(3) of the Internal Revenue Code and risk losing their tax-exempt status if they do not comply with the requirements of that section. There is a risk that Congress or the IRS could pass new laws or regulations changing the requirements for tax-exempt status, which could result in a non-profit institution losing such status. Additionally, non-profit institutions that receive federal and state appropriations face the risk of a decrease in or loss of such appropriations. Hospitals and healthcare systems are highly regulated at the federal and state levels and face burdensome state licensing requirements. There is a risk that a state could refuse to renew a hospital’s license or that the passage of new laws or regulations, especially changes to Medicare or Medicaid reimbursement, could inhibit a hospital from growing its revenues. Hospitals and healthcare systems also face risks related to increased competition from other health care providers; increased costs of inpatient and outpatient care; changes in healthcare services provided over time or during specific periods; increased pressures from managed care organizations, insurers, and patients to cut the costs of medical care; and public health emergencies. There is a risk that non¬profit institutions relying on philanthropy and donations to maintain their operations will receive less funding during economic downturns or other periods of adverse market, economic or political conditions.
Short Sales Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Short Sales Risk. The Trust may make short sales of securities. Short selling a security involves selling a borrowed security with the expectation that the value of that security will decline, so that the security may be purchased at a lower price when returning the borrowed security. If the price of the security sold short increases between the time of the short sale and the time the Trust replaces the borrowed security, the Trust will incur a loss; conversely, if the price declines, the Trust will realize a capital gain. Any gain will be decreased, and any loss will be increased, by the transaction costs incurred by the Trust, including the costs associated with providing collateral to the broker-dealer (usually cash and liquid securities) and the maintenance of collateral with its custodian. Although the Trust’s gain is limited to the price at which it sold the security short, its potential loss is theoretically unlimited and may be greater than a direct investment in the security itself because the price of the borrowed or reference security may rise. The Trust may not always be able to close out a short position at a

particular time or at an acceptable price. A lender may request that borrowed securities be returned to it on short notice, and the Trust may have to buy the borrowed securities at an unfavorable price, resulting in a loss. Short sales also subject the Trust to risks related to the lender (such as bankruptcy risks) or the general risk that the lender does not comply with its obligations.

Special Risks Related To Certain Municipal Securities [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Special Risks Related to Certain Municipal Securities. The Trust may invest in municipal leases and certificates of participation in such leases, which involve special risks not normally associated with general obligations or revenue bonds. Leases and installment purchase or conditional sale contracts (which normally provide for title to the leased asset to pass eventually to the governmental issuer) have evolved as a means for governmental issuers to acquire property and equipment without meeting the constitutional and statutory requirements for the issuance of debt. The debt issuance limitations are deemed to be inapplicable because of the inclusion in many leases or contracts of “non-appropriation” clauses that relieve the governmental issuer of any obligation to make future payments under the lease or contract unless money is appropriated for such purpose by the appropriate legislative body on a yearly or other periodic basis. In addition, such leases or contracts may be subject to the temporary abatement of payments in the event the governmental issuer is prevented from maintaining occupancy of the leased premises or utilizing the leased equipment.
Structured Finance Investments Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Structured Finance Investments Risk. The Trust’s structured finance investments may include residential and commercial mortgage-related and other asset-backed securities (“ABS”) issued by governmental entities and private issuers. Holders of structured finance investments bear risks of the underlying investments, index or reference obligation and are subject to counterparty and other risks. The Trust generally has the right to receive payments only from the structured product, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. While certain structured finance investments enable the investor to acquire interests in a pool of securities without the brokerage and other expenses associated with directly holding the same securities, investors in structured finance investments generally pay their share of the structured product’s administrative and other expenses. Although it is difficult to accurately predict whether the prices of indices and securities underlying structured finance investments will rise or fall, these prices (and, therefore, the prices of structured finance investments) will be influenced by the same types of political, economic and other events that affect issuers of securities and capital markets generally. Moreover, other types of events, domestic or international, may affect general economic conditions and financial markets, such as pandemics, armed conflicts, energy supply or price disruptions, natural disasters and man-made disasters, which may have a significant effect on the underlying assets. If the issuer of a structured product uses shorter term financing to purchase longer term securities, the issuer may be forced to sell its securities at below market prices if it experiences difficulty in obtaining short-term financing, which may adversely affect the value of the structured finance investment owned by the Trust.
Mortgage Backed Securities Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Mortgage-Backed Securities (“MBS”) Risk. MBS represent an interest in a pool of mortgages. MBS are subject to certain risks, such as: credit risk associated with the performance of the underlying mortgage properties and of the borrowers owning these properties; risks associated with their structure and execution (including the collateral, the process by which principal and interest payments are allocated and distributed to investors and how credit losses affect the return to investors in such MBS); risks associated with the servicer of the underlying mortgages; adverse changes in economic conditions and circumstances, which are more likely to have an adverse impact on MBS secured by loans on certain types of commercial properties than on those secured by loans on residential properties; prepayment and extension risks associated with the underlying assets of certain MBS, which can shorten the weighted average maturity and lower the return of the MBS, or lengthen the expected maturity, respectively, leading to significant fluctuations in the value of and income generated by the MBS; loss of all or part of the premium, if any, paid; and decline in the market value of the security, whether resulting from changes in interest rates, prepayments on the underlying mortgage collateral or perceptions of the credit risk associated with the underlying mortgage collateral. The value of MBS may be substantially dependent on the servicing of the underlying pool of mortgages. In addition, the Trust’s level of investment in MBS of a particular type or in MBS issued or guaranteed by affiliated obligors, serviced by the same servicer or backed by underlying collateral located in a specific geographic region, may subject the Trust to additional risk.

Non-agency MBS (i.e., MBS issued by commercial banks, savings and loans institutions, mortgage bankers, private mortgage insurance companies and other non-governmental issuers) are subject to the risk that the value of such securities will decline because, among other things, the securities are not guaranteed as to principal or interest by the U.S. government or a government sponsored enterprise. Non-agency MBS typically have less favorable underwriting characteristics (such as credit and default risk and collateral) and a wider range in terms (such as interest rate, term and borrower characteristics) than agency MBS. When issued in different tranches, individual tranches of nonagency MBS may subject to increased (and sometimes different) credit, prepayment and liquidity and valuation risks as compared to other tranches. Non-agency MBS are often subject to greater credit, prepayment and liquidity and valuation risks than agency MBS, and they are generally subject to greater price fluctuation and likelihood of reduced income than agency MBS, especially during periods of weakness or perceived weakness in the mortgage and real estate sectors.

The general effects of inflation on the U.S. economy can be wide-ranging, as evidenced by rising interest rates, wages and costs of consumer goods and necessities. The long-term effects of inflation on the general economy and on any individual mortgagor are unclear, and in certain cases, rising inflation and costs may affect a mortgagor’s ability to repay its related mortgage loan, thereby reducing the amount received by the holders of MBS with respect to such mortgage loan. Additionally, increased rates of inflation may negatively affect the value of certain MBS in the secondary market. MBS are particularly sensitive to changes in interest rates. During periods of declining economic conditions, losses on mortgages underlying MBS generally increase. In addition, MBS, such as CMBS

and RMBS, are subject to the risks of asset-backed securities generally and are particularly sensitive to changes in interest rates and developments in the commercial or residential real estate markets, which may adversely affect the Trust’s holdings of MBS. For example, rising interest rates generally result in a decline in the value of mortgage-related securities, such as CMBS and RMBS. MBS are also subject to risks similar to those associated with investing in real estate, such as the possible decline in the value of (or income generated by) the real estate, variations in rental income, fluctuations in occupancy levels and demand for properties or real estate-related services, changes in interest rates and changes in the availability or terms of mortgages and other financing that may render the sale or refinancing of properties difficult or unattractive.

MBS generally are classified as either CMBS or residential mortgage-backed securities (“RMBS”), each of which are subject to certain specific risks.

Commercial Mortgage-Backed Securities Risk. CMBS are subject to particular risks, such as those associated with lack of standardized terms, shorter maturities than residential mortgage loans and payment of all or substantially all of the principal only at maturity rather than regular amortization of principal. In addition, commercial lending generally is viewed as exposing the lender to a greater risk of loss than residential lending. Commercial lending typically involves larger loans to single borrowers or groups of related borrowers than residential mortgage loans. In addition, the repayment of loans secured by income producing properties typically is dependent upon the successful operation of the related real estate project and the cash flow generated therefrom. Moreover, economic decline in the businesses operated by the tenants of office properties may increase the likelihood that the tenants may be unable to pay their rents or that properties may be unable to attract or retain tenants. Moreover, other types of events, domestic or international, may affect general economic conditions and financial markets, such as pandemics, armed conflicts, energy supply or price disruptions, natural disasters and man-made disasters, which may have a significant effect on the underlying commercial mortgage loans.

Residential Mortgage-Backed Securities Risk. Home mortgage loans are typically grouped together into pools by banks and other lending institutions, and interests in these pools are then sold to investors, allowing the bank or other lending institution to have more money available to loan to home buyers. RMBS are particularly subject to the credit risk of the borrower. Credit-related risk on RMBS primarily arises from losses due to delinquencies and defaults by the borrowers in payments on the underlying mortgage loans and breaches by originators and servicers of their obligations under the underlying documentation pursuant to which the RMBS are issued. RMBS are also subject to the risks of MBS generally and the residential real estate markets. The rate of delinquencies and defaults on residential mortgage loans and the aggregate amount of the resulting losses will be affected by a number of factors, including general economic conditions, particularly those in the area where the related mortgaged property is located, the level of the borrower’s equity in the mortgaged property and the individual financial circumstances of the borrower. The risk of non-payment is greater for RMBS that are backed

by loans that were originated under weak underwriting standards, including loans made to borrowers with limited means to make repayment. RMBS are also subject to risks associated with the actions of mortgage lenders in the marketplace, which may reduce the availability of mortgage credit to prospective mortgagors. This may result in limited financing alternatives for mortgagors seeking to refinance their existing loans, which may in turn result in higher rates of delinquencies, defaults and losses on mortgages.

Income from and values of RMBS and CMBS also may be greatly affected by demographic trends, such as population shifts or changing tastes and values, or increasing vacancies or declining rents resulting from legal, cultural technological, global or local economic developments, as well as reduced demand for properties and public health conditions.

Asset Backed Securities Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Asset-Backed Securities Risk. ABS are a form of structured debt obligation. In addition to the general risks associated with credit securities discussed herein, ABS are subject to additional risks, and are particularly subject to interest rate and credit risks. During periods of declining interest rates, prepayment of borrowings underlying asset-backed securities can be expected to accelerate. Accordingly, the Trust’s ability to reinvest the returns of principal at comparable yields is subject to generally prevailing interest rates at that time. ABS are also subject to liquidity and valuation risk and, therefore, may be difficult to value accurately or sell at an advantageous time or price and involve greater transaction costs and wider bid/ask spreads than certain other instruments. While traditional fixed-income securities typically pay a fixed rate of interest until maturity, when the entire principal amount is due, an ABS represents an interest in a pool of assets that has been securitized and typically provides for monthly or other periodic payments of interest, at a fixed or floating rate, and may provide for payments of principal from the cash flow of these assets. This pool of assets (and any related assets of the issuing entity) is often the only source of payment for the ABS. The ability of an ABS issuer to make payments on the ABS, and the timing of such payments, is therefore dependent on collections on these underlying assets, which may be insufficient to make interest and principal payments. The recoveries on the underlying collateral may not, in some cases, be sufficient to support payments on these securities, or may be unavailable in the event of a default and enforcing rights with respect to these assets or collateral may be difficult and costly, which may result in losses to investors in an ABS. The collateral underlying ABS may constitute assets related to a wide range of industries such as credit card and automobile receivables or other assets derived from consumer, commercial or corporate sectors, and these underlying assets may be secured or unsecured. ABS are particularly subject to interest rate risk and credit risk.
C L O C D O And C B O Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] CLO, CDO and CBO Risk. In addition to the general risks (such as interest rate risk, prepayment risk, extension risk, market risk, credit risk and liquidity and valuation risk) associated with debt securities discussed herein, collateralized loan obligations (“CLOs”), collateralized debt obligations (“CDOs”), and collateralized bond obligations (“CBOs”) are subject to additional risks due to their complex structure and highly leveraged nature, such as higher risk of volatility and magnified financial losses. CLOs, CDOs and CBOs are subject to risks associated with the possibility that

distributions from collateral securities may not be adequate to make interest or other payments. The value of and income from securities issued by CLOs, CDOs and CBOs also may decrease because of, among other developments, changes in market value; underlying loan, debt or bond defaults or delinquencies; changes in the market’s perception of the creditworthiness of the servicer of the assets, the originator of an asset in the pool, or the financial institution or fund providing the credit support or enhancement; loan performance and prices; broader market sentiment, including expectations regarding future loan defaults; liquidity conditions; and supply and demand for structured products. Additionally, the indirect investment structure of CLOs, CDOs and CBOs presents certain risks to the Trust such as less liquidity compared with holding the underlying assets directly. CLOs, CDOs and CBOs normally charge management fees and administrative expenses, which would be borne by the Trust. The terms of many structured finance investments, including CLOs, CDOs and CBOs, are tied to the Secured Overnight Financing Rate (“SOFR”) or other reference rates based on SOFR. These relatively new and developing rates may not match the reference rate applicable to the underlying assets related to these investments.

Taxable Municipal Securities Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Taxable Municipal Securities Risk. Taxable municipal securities are subject to the general risks associated with municipal securities. While interest earned on municipal securities is generally not subject to federal tax, any interest earned on taxable municipal securities is fully taxable at the federal level and may be subject state and/or local income tax. Additionally, litigation, legislation or other political events, local business or economic conditions or the bankruptcy of the issuer could have a significant effect on the ability of an issuer of municipal securities to make payments of principal and/ or interest. Political changes and uncertainties in the municipal market related to taxation, legislative changes or the rights of municipal security holders can significantly affect municipal securities. Because many securities are issued to finance similar projects, especially those relating to education, health care, transportation and utilities, conditions in those sectors can adversely affect the overall municipal market. In addition, changes in the financial condition of an individual municipal issuer can adversely affect the overall municipal market.
Valuation Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Valuation Risk. GPIM may use the fair value method to value investments if market quotations for them are not readily available or are deemed unreliable. The Trust may also fair value securities and assets when a significant event is deemed to have occurred after the time of a market quotation, including for securities and assets traded on foreign markets and securities and assets for which market quotations are provided by independent third party pricing services as of a time that is prior to the time when the Trust determines its NAV. Because the secondary markets for certain investments may be limited, they may be particularly difficult to value. Where market quotations are not readily available, valuation may require more research than for more liquid investments. In addition, elements of judgment may play a greater role in valuation in such cases than for investments with a more active secondary market because there is less reliable objective data available. A security that is fair valued may be valued at a price higher or lower than the value determined by other funds using

their own fair valuation procedures. Prices obtained by the Trust upon the sales of such securities may not equal the value at which the Trust carried the investment on its books, which would adversely affect the net asset value of the Trust.

Right Of Reorganization Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] In addition to the foregoing risks, investors should note that the Trust reserves the right to merge or reorganize with another fund, liquidate or convert into an open-end fund, in each case subject to applicable approvals by shareholders and the Trust’s Board of Trustees as required by law and the Trust’s governing documents.
Interest Rate Risk [Member]  
General Description of Registrant [Abstract]  
Risk [Text Block] Interest Rate Risk. Fixed-income and other debt instruments are subject to the possibility that interest rates could change (or are expected to change). Changes in interest rates (or the expectation of such changes) can be sudden, significant and frequent and may adversely affect the Trust’s investments in these instruments, such as the value or liquidity of, and income generated by, the investments or increase risks associated with such investments, such as credit or default risks. In addition, changes in interest rates can have unpredictable effects on markets and can adversely affect the Trust’s yield, income and performance. Generally, when interest rates increase, the values of fixed-income and other debt instruments decline, and when interest rates decrease, the values of fixed-income and other debt instruments rise. Changes in interest rates may also adversely affect the yield generated by certain fixed-income and other debt securities (“Income Securities”) or result in the issuance of lower yielding Income Securities. The Federal Reserve has changed interest rates recently in response to economic conditions, including inflation rates. The Federal Reserve’s actions present heightened risks to fixed-income and debt instruments, and such risks could be even further heightened if these actions are unexpectedly or suddenly reversed or are ineffective in achieving their desired outcomes. It is difficult to accurately predict how long, and whether, the Federal Reserve’s current stance on interest rates will persist and the impact these actions will have on the economy and the Trust’s investments and the markets where they trade. The Federal Reserve’s monetary policy is subject to change at any time and potentially frequently based on a variety of market and economic conditions.
