Company Act of 1940, as amended (the "1940 Act"), and is permitted to invest a
greater proportion of its assets in the securities of a smaller number of issuers.

However, the fund &lt;br /&gt;expects to engage in frequent trading of derivatives, which could have &lt;br /&gt;tax consequences that impact shareholders, such as the realization of &lt;br /&gt;taxable short-term capital gains. In addition, the fund could incur &lt;br /&gt;transaction costs, such as commissions, when it buys and sells securities &lt;br /&gt;and other instruments. Transaction costs, which are not reflected in annual &lt;br /&gt;fund operating expenses or in the example, affect the fund&apos;s performance.&lt;/tt&gt;</rr:PortfolioTurnoverTextBlock>

To pursue&lt;br /&gt;this goal, the fund invests under normal circumstances in commodity-linked&lt;br /&gt;derivative instruments that provide exposure to the investment returns of the&lt;br /&gt;commodities markets without investing directly in physical commodities, backed&lt;br /&gt;by an actively managed portfolio of fixed income securities. Commodities are&lt;br /&gt;assets that have tangible properties, such as oil, metals, and agricultural&lt;br /&gt;products. The fund does not intend to invest in commodities directly.&lt;br /&gt; &lt;br /&gt;The Index, which is calculated and maintained by an affiliate of Credit Suisse&lt;br /&gt;Asset Management, LLC, the fund&apos;s investment adviser ("Credit Suisse"), is&lt;br /&gt;designed to be an investable, diversified benchmark for commodities as an asset&lt;br /&gt;class. The Index is an unmanaged index composed of (i) futures contracts on&lt;br /&gt;physical commodities within the following five commodity sectors: energy,&lt;br /&gt;industrial metals, precious metals, agriculture and livestock, and (ii) short&lt;br /&gt;maturity Treasury bills. The commodities represented in the Index are determined&lt;br /&gt;annually based on world production levels and global exchange market liquidity&lt;br /&gt;and the portion represented by each commodity sector and commodity within the&lt;br /&gt;sector will vary depending on market conditions. The Index is rebalanced&lt;br /&gt;monthly, which is intended to provide diversification across commodities and&lt;br /&gt;commodity sectors over time, but the Index, and thereby the fund, could have&lt;br /&gt;large exposures to a single commodity or a small number of commodities at any&lt;br /&gt;particular time.&lt;br /&gt; &lt;br /&gt;The fund intends to gain exposure to commodities markets by investing primarily&lt;br /&gt;in the Credit Suisse Cayman Commodity ACCESS Strategy Fund, Ltd, a wholly-owned&lt;br /&gt;subsidiary of the fund organized under the laws of the Cayman Islands (the&lt;br /&gt;"Subsidiary"), which in turn invests primarily in commodity-linked derivative&lt;br /&gt;instruments, including commodity-linked swap agreements, options, futures and&lt;br /&gt;options on futures. The fund may also gain exposure to commodities markets by&lt;br /&gt;investing directly in commodity-linked structured notes and other commodity-linked &lt;br /&gt;derivative instruments. The derivative instruments in which the fund and the &lt;br /&gt;Subsidiary invest are instruments linked to the Index, other commodity indices &lt;br /&gt;or the value of a particular commodity or commodity futures contract or subset &lt;br /&gt;of commodities or commodity futures contracts. These instruments may specify &lt;br /&gt;exposure to commodity futures with different commodities, roll dates, reset &lt;br /&gt;dates or contract months than those specified by the Index. As a result, the &lt;br /&gt;commodity-linked derivatives component of the fund&apos;s portfolio may deviate &lt;br /&gt;from the returns of the Index. The fund is actively managed and not an index &lt;br /&gt;fund and its performance will vary from the Index, perhaps materially. The fund &lt;br /&gt;or the Subsidiary will over-weight or under-weight its exposure to a particular&lt;br /&gt;commodity, or a subset of commodities, to a significant extent, such that the&lt;br /&gt;fund has greater or lesser exposure to a subset of commodities than is&lt;br /&gt;represented by the Index. The portion of the fund&apos;s or Subsidiary&apos;s assets&lt;br /&gt;exposed to any particular commodity or commodity sector will vary based on&lt;br /&gt;market conditions, but from time to time the portion could be substantial.&lt;br /&gt; &lt;br /&gt;The Subsidiary may use derivatives to obtain significant amounts of long or&lt;br /&gt;short exposure in an attempt to increase the Subsidiary&apos;s income or gain, to&lt;br /&gt;hedge various investments or for risk management. The long and short positions&lt;br /&gt;held by the Subsidiary will vary in size as market opportunities change. The&lt;br /&gt;notional value of the fund&apos;s commodity-related long positions and their&lt;br /&gt;equivalents are currently expected to range between 80% and 150% of the value of&lt;br /&gt;the fund&apos;s net assets. The notional value of the fund&apos;s commodity-related short&lt;br /&gt;positions and their equivalents are currently expected to range between 0% and&lt;br /&gt;50% of the value of the fund&apos;s net assets. In rising markets, the fund expects&lt;br /&gt;that the value of the long positions will appreciate more rapidly than the short&lt;br /&gt;positions, and in declining markets, that the value of the short positions will&lt;br /&gt;appreciate more rapidly than the long positions.&lt;br /&gt; &lt;br /&gt;The fund may invest up to 25% of its total assets in the Subsidiary. The fund&lt;br /&gt;will invest in the Subsidiary primarily to gain exposure to the commodities&lt;br /&gt;markets within the limitations of the federal tax laws, rules and regulations&lt;br /&gt;that apply to registered investment companies. Generally, the Subsidiary will&lt;br /&gt;invest in commodity-linked derivative instruments, but it will also invest in&lt;br /&gt;fixed income instruments, including U.S. government securities, U.S. government&lt;br /&gt;agency securities, corporate bonds, debentures and notes, mortgage-backed and&lt;br /&gt;other asset-backed securities, event-linked bonds, loan participations, bank&lt;br /&gt;certificates of deposit, fixed time deposits, bankers&apos; acceptances, commercial&lt;br /&gt;paper and other short-term fixed income securities. The primary purpose of the&lt;br /&gt;fixed income instruments held by the Subsidiary will be to serve as collateral&lt;br /&gt;for the Subsidiary&apos;s derivative positions; however, these instruments are also&lt;br /&gt;expected to earn income for the Subsidiary.&lt;br /&gt; &lt;br /&gt;The annualized volatility level of the Index has historically ranged between &lt;br /&gt;15% and 35%. The fund&apos;s annualized volatility level could be higher or lower&lt;br /&gt;depending on market conditions and the fund&apos;s investments. Volatility is a&lt;br /&gt;measure of the change in price of an asset over time and a higher volatility&lt;br /&gt;level means that an asset&apos;s value will increase or decrease by larger amounts&lt;br /&gt;over a time period than an asset with a lower volatility level.&lt;br /&gt; &lt;br /&gt;Credit Suisse manages the commodity-related portion of the fund&apos;s portfolio,&lt;br /&gt;including the portion invested through the Subsidiary, pursuant to a process &lt;br /&gt;that employs a proprietary quantitative model and qualitative investment &lt;br /&gt;techniques. Through this process, Credit Suisse will over-weight or under-weight, &lt;br /&gt;versus the Index, the fund&apos;s and/or the Subsidiary&apos;s exposure to the components &lt;br /&gt;of the Index. Credit Suisse&apos;s process is designed to provide insight into &lt;br /&gt;forecasting component returns, managing portfolio risk and executing trades &lt;br /&gt;efficiently.&lt;br /&gt; &lt;br /&gt;FIXED INCOME STRATEGY&lt;br /&gt; &lt;br /&gt;Assets of the fund not invested in commodity-linked structured notes, other&lt;br /&gt;commodity-linked derivative instruments or the Subsidiary will be invested &lt;br /&gt;in fixed income instruments. The fixed income instruments in which the fund &lt;br /&gt;may invest include, but are not limited to, U.S. government securities, U.S.&lt;br /&gt;government agency securities, corporate bonds, debentures and notes,&lt;br /&gt;mortgage-backed and other asset-backed securities, event-linked bonds, loan&lt;br /&gt;participations, bank certificates of deposit, fixed time deposits, bankers&apos;&lt;br /&gt;acceptances, commercial paper and other short-term fixed income securities. &lt;br /&gt;The fund&apos;s fixed income instrument holdings serve as collateral for the &lt;br /&gt;fund&apos;s derivative positions and also earn income for the fund.&lt;br /&gt; &lt;br /&gt;Credit Suisse manages the fixed income investments portion of the fund&apos;s&lt;br /&gt;portfolio by taking into account differences in yields among securities of&lt;br /&gt;different maturities, market sectors and issuers. Under normal market conditions, &lt;br /&gt;at least 90% of the fund&apos;s fixed income instruments (excluding structured notes) &lt;br /&gt;will be investment grade. In determining the credit quality of a security, Credit &lt;br /&gt;Suisse will use the highest rating assigned to it. The average portfolio duration &lt;br /&gt;of the fixed income portion of the fund will vary based on Credit Suisse&apos;s forecast &lt;br /&gt;for interest rates, and under normal market conditions is not expected to exceed &lt;br /&gt;one year.&lt;br /&gt; &lt;br /&gt;The fund is "non-diversified," meaning that a relatively high percentage of &lt;br /&gt;its assets may be invested in a limited number of issuers of securities. The &lt;br /&gt;fund will not invest 25% or more of its total assets in instruments issued by&lt;br /&gt;companies in any one industry. However, 25% or more of its total assets may be&lt;br /&gt;indirectly exposed to industries in one or more of the five commodity sectors&lt;br /&gt;represented in the Index. In addition, the fund can invest more than 25% of &lt;br /&gt;its total assets in instruments (such as structured notes) issued by companies &lt;br /&gt;in the financial services sector (which includes the banking, brokerage and&lt;br /&gt;insurance industries). In that case, the fund&apos;s share value will fluctuate in&lt;br /&gt;response to events affecting issues in those sectors.&lt;/tt&gt;</rr:StrategyNarrativeTextBlock>

Before you invest,&lt;br /&gt;please make sure you understand the risks that apply to the fund. As with any&lt;br /&gt;mutual fund, you could lose money over any period of time.&lt;br /&gt; &lt;br /&gt;The fund is not a complete investment program and should only form a part of a&lt;br /&gt;diversified portfolio.

Investors in the fund should be willing to assume the &lt;br /&gt;risks of potentially significant short-term share price fluctuations.&lt;br /&gt; &lt;br /&gt;Investments in the fund are not bank deposits and are not insured or guaranteed&lt;br /&gt;by the Federal Deposit Insurance Corporation or any other government agency.&lt;br /&gt; &lt;br /&gt;CFTC REGULATION&lt;br /&gt; &lt;br /&gt;Due to recent Commodity Futures Trading Commission ("CFTC") rule amendments, the &lt;br /&gt;disclosures and operations of the fund will need to comply with applicable&lt;br /&gt;regulations governing commodity pools, which will increase the fund&apos;s regulatory&lt;br /&gt;compliance costs. Other potentially adverse regulatory initiatives could develop.&lt;br /&gt; &lt;br /&gt;COMMODITY RISK&lt;br /&gt; &lt;br /&gt;The fund&apos;s and the Subsidiary&apos;s investments in commodity-linked derivative&lt;br /&gt;instruments may subject the fund to greater volatility than investments in&lt;br /&gt;traditional securities, particularly if the investments involve leverage. The&lt;br /&gt;value of commodity-linked derivative instruments may be affected by changes in&lt;br /&gt;overall market movements, commodity index volatility, changes in interest rates,&lt;br /&gt;or factors affecting a particular industry or commodity, such as drought, floods, &lt;br /&gt;weather, livestock disease, embargoes, tariffs and international economic, &lt;br /&gt;political and regulatory developments.&lt;br /&gt; &lt;br /&gt;Use of leveraged commodity-linked derivatives creates an opportunity for increased &lt;br /&gt;return but, at the same time, creates the possibility for greater loss (including &lt;br /&gt;the likelihood of greater volatility of the fund&apos;s net asset value), and there can &lt;br /&gt;be no assurance that the fund&apos;s use of leverage will be successful.&lt;br /&gt; &lt;br /&gt;CREDIT RISK&lt;br /&gt; &lt;br /&gt;The issuer of a debt instrument, the borrower of a loan or the counterparty to a&lt;br /&gt;contract, including derivatives contracts, may default or otherwise become unable &lt;br /&gt;to honor a financial obligation. Changes in an issuer&apos;s credit rating or the &lt;br /&gt;market&apos;s perception of an issuer&apos;s creditworthiness also may affect the value of &lt;br /&gt;the fund&apos;s investment in that issuer. Non-investment grade securities carry a &lt;br /&gt;higher risk of default and should be considered speculative.&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;DERIVATIVES RISK&lt;br /&gt; &lt;br /&gt;Derivatives are financial contracts whose values depend on, or is derived from, &lt;br /&gt;the value of an underlying asset, instrument or index. The fund&apos;s use of derivative &lt;br /&gt;instruments, particularly commodity-linked derivatives, involves risks different &lt;br /&gt;from, or possibly greater than, the risks associated with investing directly in &lt;br /&gt;securities and other traditional investments. Derivatives are subject to a number &lt;br /&gt;of risks described elsewhere in this Prospectus, such as commodity risk, liquidity &lt;br /&gt;risk, interest rate risk, market risk and credit risk. Also, suitable derivative &lt;br /&gt;transactions may not be available in all circumstances.&lt;br /&gt; &lt;br /&gt;FIXED INCOME RISK&lt;br /&gt; &lt;br /&gt;The market value of fixed income investments will change in response to interest&lt;br /&gt;rate changes and other factors, such as changes in the effective maturities and&lt;br /&gt;credit ratings of fixed income investments. During periods of falling interest&lt;br /&gt;rates, the values of outstanding fixed income securities and related financial&lt;br /&gt;instruments generally rise. Conversely, during periods of rising interest rates,&lt;br /&gt;the values of such securities and related financial instruments generally decline. &lt;br /&gt;Fixed income investments are also subject to credit risk.&lt;br /&gt; &lt;br /&gt;FOCUS RISK&lt;br /&gt; &lt;br /&gt;If the fund is exposed to a significant extent to a particular commodity or&lt;br /&gt;subset of commodities, the fund will be more exposed to the specific risks&lt;br /&gt;relating to such commodity or commodities and will be subject to greater&lt;br /&gt;volatility than if it were more broadly diversified among commodity sectors.&lt;br /&gt; &lt;br /&gt;FUTURES CONTRACTS RISK&lt;br /&gt; &lt;br /&gt;The risks associated with the fund&apos;s use of futures contracts and swaps and&lt;br /&gt;structured notes that reference the price of futures contracts include the &lt;br /&gt;risk that: (i) changes in the price of a futures contract may not always track &lt;br /&gt;the changes in market value of the underlying reference asset; (ii) trading&lt;br /&gt;restrictions or limitations may be imposed by an exchange, and government&lt;br /&gt;regulations may restrict trading in futures contracts; and (iii) if the fund &lt;br /&gt;has insufficient cash to meet margin requirements, the fund may need to sell &lt;br /&gt;other investments, including at disadvantageous times.&lt;br /&gt; &lt;br /&gt;INTEREST RATE RISK&lt;br /&gt; &lt;br /&gt;Changes in interest rates may cause a decline in the market value of an investment. &lt;br /&gt;With bonds and other fixed income securities, a rise in interest rates typically &lt;br /&gt;causes a fall in values, while a fall in interest rates typically causes a rise in &lt;br /&gt;values. Generally, the longer the maturity or duration of a debt instrument, the &lt;br /&gt;greater the impact of a charge in interest on the instrument&apos;s value.&lt;br /&gt; &lt;br /&gt;LEVERAGING RISK&lt;br /&gt; &lt;br /&gt;The fund may invest in certain derivatives that provide leveraged exposure. The&lt;br /&gt;fund&apos;s investment in these instruments generally requires a small investment &lt;br /&gt;relative to the amount of investment exposure assumed. As a result, such &lt;br /&gt;investments may cause the fund to lose more than the amount it invested in those &lt;br /&gt;instruments. The net asset value of the fund when employing leverage will be more &lt;br /&gt;volatile and sensitive to market movements. Leverage may involve the creation of &lt;br /&gt;a liability that requires the portfolio to pay interest.&lt;br /&gt; &lt;br /&gt;LIQUIDITY RISK&lt;br /&gt; &lt;br /&gt;Certain portfolio holdings, such as commodity-linked notes and swaps, may be&lt;br /&gt;difficult or impossible to sell at the time and the price that the fund would&lt;br /&gt;like. The fund may have to lower the price, sell other holdings instead or forgo&lt;br /&gt;an investment opportunity. Any of these could have a negative effect on&lt;br /&gt;portfolio management or performance.&lt;br /&gt; &lt;br /&gt;MARKET RISK&lt;br /&gt; &lt;br /&gt;The market value of an instrument may fluctuate, sometimes rapidly and&lt;br /&gt;unpredictably. These fluctuations, which are often referred to as "volatility,"&lt;br /&gt;may cause an instrument to be worth less than it was worth at an earlier time.&lt;br /&gt;Market risk may affect a single issuer, industry, sector of the economy, or the&lt;br /&gt;market as a whole. Market risk is common to most investments - including stocks,&lt;br /&gt;bonds and commodities, and the mutual funds that invest in them.&lt;br /&gt; &lt;br /&gt;MANAGER/MODEL RISK&lt;br /&gt; &lt;br /&gt;If the fund&apos;s portfolio managers make poor investment decisions, it will&lt;br /&gt;negatively affect the fund&apos;s performance. The fund also bears the risk that &lt;br /&gt;the proprietary model used by the portfolio managers will not be successful in&lt;br /&gt;identifying investments that will help the fund achieve its investment objective, &lt;br /&gt;causing the fund to underperform its benchmark or other funds with a similar &lt;br /&gt;investment objective.&lt;br /&gt; &lt;br /&gt;NON-DIVERSIFIED STATUS&lt;br /&gt; &lt;br /&gt;The fund is considered a non-diversified investment company under the Investment&lt;br /&gt;Company Act of 1940, as amended (the "1940 Act"), and is permitted to invest a&lt;br /&gt;greater proportion of its assets in the securities of a smaller number of issuers. &lt;br /&gt;As a result, the fund may be subject to greater volatility with respect to its &lt;br /&gt;portfolio securities than a fund that is diversified.&lt;br /&gt; &lt;br /&gt;PORTFOLIO TURNOVER RISK&lt;br /&gt; &lt;br /&gt;The fund expects to engage in frequent trading of derivatives. Active and frequent &lt;br /&gt;trading may lead to the realization and distribution to shareholders of higher &lt;br /&gt;short-term capital gains, which would increase their tax liability. Frequent &lt;br /&gt;trading also increases transaction costs, which could detract from the fund&apos;s &lt;br /&gt;performance.&lt;br /&gt; &lt;br /&gt;SHORT POSITION RISK&lt;br /&gt; &lt;br /&gt;The fund or the Subsidiary may enter into a short position through a futures&lt;br /&gt;contract or swap agreement. Taking short positions involves leverage of the&lt;br /&gt;fund&apos;s or the Subsidiary&apos;s assets and presents various risks. If the price of&lt;br /&gt;the asset, instrument or market on which the fund or the Subsidiary has taken &lt;br /&gt;a short position increases, then the fund or the Subsidiary will incur a loss &lt;br /&gt;equal to the increase in price from the time that the short position was &lt;br /&gt;entered into plus any premiums and interest paid to a third party. Therefore, &lt;br /&gt;taking short positions involves the risk that losses may be exaggerated, &lt;br /&gt;potentially losing more money than the actual cost of the investment. The &lt;br /&gt;fund&apos;s or the Subsidiary&apos;s loss on a short sale could theoretically be &lt;br /&gt;unlimited in a case where the fund or the Subsidiary, as the case may be, is &lt;br /&gt;unable, for whatever reason, to close out its short position. The fund&apos;s risk &lt;br /&gt;of loss with respect to short sales may be significant, as the fund may have &lt;br /&gt;a substantial amount of short positions in its portfolio.&lt;br /&gt; &lt;br /&gt;SPECULATIVE EXPOSURE RISK&lt;br /&gt; &lt;br /&gt;Gains or losses from speculative positions in a derivative may be much greater&lt;br /&gt;than the derivative&apos;s original cost. For example, potential losses from swaps&lt;br /&gt;and speculative short sales are unlimited.&lt;br /&gt; &lt;br /&gt;STRUCTURED NOTE RISK&lt;br /&gt; &lt;br /&gt;The value of a structured note will be influenced by time to maturity, level &lt;br /&gt;of supply and demand for the type of note, interest rate and market volatility,&lt;br /&gt;changes in the issuer&apos;s credit rating, and economic, legal, political, or&lt;br /&gt;geographic events that affect the reference asset. In addition, there may be &lt;br /&gt;a lag between a change in the value of the underlying reference asset and the&lt;br /&gt;value of the structured note.&lt;br /&gt; &lt;br /&gt;SUBSIDIARY RISK&lt;br /&gt; &lt;br /&gt;By investing in the Subsidiary, the fund is indirectly exposed to the risks&lt;br /&gt;associated with the Subsidiary&apos;s investments. The derivatives and other&lt;br /&gt;investments held by the Subsidiary are generally similar to those that are&lt;br /&gt;permitted to be held by the fund and are subject to the same risks that apply &lt;br /&gt;to similar investments if held directly by the fund. These risks are described&lt;br /&gt;elsewhere in this Prospectus. There can be no assurance that the investment&lt;br /&gt;objective of the Subsidiary will be achieved.&lt;br /&gt; &lt;br /&gt;The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted&lt;br /&gt;in this Prospectus, is not subject to all the investor protections of the 1940&lt;br /&gt;Act. However, the fund wholly owns and controls the Subsidiary, and the fund and&lt;br /&gt;the Subsidiary are both managed by Credit Suisse, making it unlikely that the&lt;br /&gt;Subsidiary will take action contrary to the interests of the fund and its&lt;br /&gt;shareholders. The fund&apos;s Board of Trustees has oversight responsibility for the&lt;br /&gt;investment activities of the fund, including its investment in the Subsidiary,&lt;br /&gt;and the fund&apos;s role as sole shareholder of the Subsidiary. The Subsidiary will&lt;br /&gt;be subject to the same investment restrictions and limitations, and follow the&lt;br /&gt;same compliance policies and procedures as the fund.&lt;br /&gt; &lt;br /&gt;Changes in the laws of the United States and/or the Cayman Islands could result&lt;br /&gt;in the inability of the fund and/or the Subsidiary to continue to operate as it &lt;br /&gt;does currently and could adversely affect the fund.&lt;br /&gt; &lt;br /&gt;SWAP AGREEMENTS RISK&lt;br /&gt; &lt;br /&gt;Swap agreements involve the risk that the party with whom the fund has entered&lt;br /&gt;into the swap will default on its obligation to pay the fund and the risk that&lt;br /&gt;the fund will not be able to meet its obligations to pay the other party to the&lt;br /&gt;agreement.&lt;br /&gt; &lt;br /&gt;TAX RISK&lt;br /&gt; &lt;br /&gt;In order to qualify as a Regulated Investment Company (a "RIC") under the&lt;br /&gt;Internal Revenue Code of 1986, as amended (the "Code"), the fund must meet&lt;br /&gt;certain requirements regarding the source of its income, the diversification &lt;br /&gt;of its assets and the distribution of its income. The Internal Revenue Service&lt;br /&gt;("IRS") has issued a ruling that income realized from certain types of&lt;br /&gt;commodity-linked derivatives would not be qualifying income. As a result, the&lt;br /&gt;fund&apos;s ability to realize income from investments in such commodity-linked&lt;br /&gt;derivatives as part of its investment strategy would be limited to a maximum &lt;br /&gt;of 10% of its gross income. If the fund fails to qualify as a RIC, the fund &lt;br /&gt;will be subject to federal income tax on its net income at regular corporate &lt;br /&gt;rates (without reduction for distributions to shareholders). When distributed, &lt;br /&gt;that income also would be taxable to shareholders as an ordinary dividend to the&lt;br /&gt;extent attributable to the fund&apos;s earnings and profits. If the fund were to fail&lt;br /&gt;to qualify as a RIC and became subject to federal income tax, shareholders of&lt;br /&gt;the fund would be subject to diminished returns.&lt;br /&gt; &lt;br /&gt;The IRS has issued private letter rulings to registered investment companies&lt;br /&gt;concluding that income derived from their investment in a wholly-owned&lt;br /&gt;subsidiary and certain commodity-linked structured notes would constitute&lt;br /&gt;qualifying income to the fund. The IRS has indicated that the granting of these&lt;br /&gt;types of private letter rulings is currently suspended, pending further internal&lt;br /&gt;discussion. As a result, the fund has not received and there can be no assurance&lt;br /&gt;that the IRS will grant, such a private letter ruling to the fund. If the fund&lt;br /&gt;does not request and receive such a private letter ruling, there is a risk that&lt;br /&gt;the IRS could assert that the income derived from the fund&apos;s investment in the&lt;br /&gt;Subsidiary and certain commodity-linked structured notes will not be considered&lt;br /&gt;qualifying income for purposes of the fund remaining qualified as a RIC for U.S.&lt;br /&gt;federal income tax purposes.&lt;br /&gt; &lt;br /&gt;U.S. GOVERNMENT SECURITIES RISK&lt;br /&gt; &lt;br /&gt;Obligations of U.S. government agencies and authorities are supported by varying&lt;br /&gt;degrees of credit but generally are not backed by the full faith and credit of&lt;br /&gt;the U.S. government. No assurance can be given that the U.S. government will&lt;br /&gt;provide financial support to its agencies and authorities if it is not obligated&lt;br /&gt;by law to do so.&lt;br /&gt; &lt;br /&gt;VALUATION RISK&lt;br /&gt; &lt;br /&gt;The lack of an active trading market may make it difficult to obtain an accurate&lt;br /&gt;price for an instrument held by the fund. Many derivative instruments are not&lt;br /&gt;actively traded.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>
