Derivatives are financial instruments with a value in &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;relation to, or derived from, the value of an underlying asset(s) or other reference, such as an index, rate or other &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;economic indicator (each an underlying reference). Derivatives may include those that are privately placed or &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;otherwise exempt from SEC registration, including certain Rule 144A eligible securities. Derivatives could result in &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;Fund losses if the underlying reference does not perform as anticipated. Use of derivatives is a highly specialized &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;activity that can involve investment techniques, risks, and tax planning different from those associated with more &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;traditional investment instruments.

A relatively small movement in the price, rate or other economic indicator associated with the underlying &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;reference may result in substantial losses for the Fund. Derivatives may be more volatile than other types of &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;investments. The value of derivatives may be influenced by a variety of factors, including national and international &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;political and economic developments. Potential changes to the regulation of the derivatives markets may make &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;derivatives more costly, may limit the market for derivatives, or may otherwise adversely affect the value or &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;performance of derivatives. Derivatives can increase the Fund&#x2019;s risk exposure to underlying references and their &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;attendant risks, such as credit risk, market risk, foreign currency risk and interest rate risk, while potentially exposing &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;the Fund to correlation risk, counterparty risk, hedging risk, inflation risk, leverage risk, liquidity risk, pricing risk and &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;volatility risk.&lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

The seller hopes that the &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;market price on the delivery date is less than the agreed upon price, while the buyer hopes for the contrary. Certain &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;futures contract markets are highly volatile, and futures contracts may be illiquid. Futures exchanges may limit &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;fluctuations in futures contract prices by imposing a maximum permissible daily price movement. The Fund may be &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;disadvantaged if it is prohibited from executing a trade outside the daily permissible price movement. At or prior to &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;maturity of a futures contract, the Fund may enter into an offsetting contract and may incur a loss to the extent there &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;has been adverse movement in futures contract prices. The liquidity of the futures markets depends on participants &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;entering into offsetting transactions rather than making or taking delivery. To the extent participants make or take &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;delivery, liquidity in the futures market could be reduced. Because of the low margin deposits normally required in &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;futures trading, it is possible that the Fund may employ a high degree of leverage in the portfolio.

For certain types of futures contracts, losses are potentially unlimited.

The ability of &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;the Fund to realize its investment objective will depend, in large part, on the extent to which the Underlying Funds &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;realize their investment objective. There is no guarantee that the Underlying Funds will achieve their respective &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:12.0pt;text-align:left;"&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;investment objectives. The Fund is exposed to the same risks as the Underlying Funds in direct proportion to the &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;allocation of its assets among the Underlying Funds. Therefore, to the extent that the Fund invests significantly in a &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;particular Underlying Fund, the Fund&#x2019;s performance would be significantly impacted by the performance of such &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;Underlying Fund. Generally, by investing in a combination of Underlying Funds, the Fund has exposure to the risks of &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;many areas of the market. By concentrating its investments in relatively few Underlying Funds, the Fund may have &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;more concentrated market exposures, subjecting the Fund to greater risk of loss should those markets decline or fail &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;to rise. The performance of Underlying Funds could be adversely affected if other entities that invest in the same &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;funds make relatively large investments or redemptions in such funds. The Fund, and its shareholders, indirectly bear &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;a portion of the expenses of any funds in which the Fund invests. Because the expenses and costs of each &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;Underlying Fund are shared by its investors, redemptions by other investors in an Underlying Fund could result in &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;decreased economies of scale and increased operating expenses for such Underlying Fund. The Investment &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;Manager has a conflict of interest in choosing affiliated funds over unaffiliated funds when selecting and investing in &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;Underlying Funds because it receives management fees from affiliated funds, and it has a conflict in choosing &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;among affiliated funds when selecting and investing in Underlying Funds, because the fees paid to it by certain &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;affiliated funds are higher than the fees paid by other affiliated funds. Also, to the extent that the Fund is &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;constrained/restricted from investing (or investing further) in a particular Underlying Fund for one or more reasons &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;(e.g., Underlying Fund capacity constraints or regulatory restrictions) or if the Fund chooses to sell its investment in &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;an Underlying Fund because of poor investment performance or for other reasons, the Fund may have to invest in &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;another fund(s), including less desirable funds &#x2013; from a strategy or investment performance standpoint &#x2013; which &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;could have a negative impact on Fund performance. In addition, Fund performance could be negatively impacted if &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;the Investment Manager is unable to identify an appropriate alternate fund(s) in a timely manner or at all.&lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

In addition, these investments have greater price fluctuations, are less liquid and &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;are more likely to experience a default than higher-rated debt instruments.

In general, if interest &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;liquidity of the Fund&#x2019;s investments in debt instruments. In general, the longer the maturity or duration of a debt &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;instrument, the greater its sensitivity to changes in interest rates. For example, a three-year duration means a bond is &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;expected to decrease in value by 3% if interest rates rise 1% and increase in value by 3% if interest rates fall 1%. &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;risk. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;Actions by governments and central banking authorities can result in increases or decreases in interest rates. Higher &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;periods of inflation could lead such authorities to raise interest rates. Such actions may negatively affect the value of &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;debt instruments held by the Fund, resulting in a negative impact on the Fund's performance and NAV. Any interest &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;rate increases could cause the value of the Fund&#x2019;s investments in debt instruments to decrease. Rising interest rates &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;advantageous to do so, which could result in losses.&lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

In the case of &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;prepayment risk, if the investment is converted, prepaid or redeemed before maturity, the portfolio managers may &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;not be able to invest the proceeds in other investments providing as high a level of income, resulting in a reduced &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;yield to the Fund. As interest rates decrease or spreads narrow on such investments, the likelihood of prepayment &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;increases. Conversely, extension risk is the risk that an unexpected rise in interest rates will extend the life of an &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;investment beyond the prepayment time. If the Fund&#x2019;s investments are locked in at a lower interest rate for a longer &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;period of time, the portfolio managers may be unable to capitalize on investments with higher interest rates or wider &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;spreads.&lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

Derivatives are financial instruments with a value in &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;relation to, or derived from, the value of an underlying asset(s) or other reference, such as an index, rate or other &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;economic indicator (each an underlying reference). Derivatives may include those that are privately placed or &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;otherwise exempt from SEC registration, including certain Rule 144A eligible securities. Derivatives could result in &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;Fund losses if the underlying reference does not perform as anticipated. Use of derivatives is a highly specialized &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;activity that can involve investment techniques, risks, and tax planning different from those associated with more &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;traditional investment instruments.

A relatively small movement in the price, rate or other economic indicator associated with the underlying &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;reference may result in substantial losses for the Fund. Derivatives may be more volatile than other types of &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;investments. The value of derivatives may be influenced by a variety of factors, including national and international &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;political and economic developments. Potential changes to the regulation of the derivatives markets may make &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;derivatives more costly, may limit the market for derivatives, or may otherwise adversely affect the value or &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;performance of derivatives.

The seller hopes that the &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;market price on the delivery date is less than the agreed upon price, while the buyer hopes for the contrary. Certain &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;futures contract markets are highly volatile, and futures contracts may be illiquid. Futures exchanges may limit &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;fluctuations in futures contract prices by imposing a maximum permissible daily price movement. The Fund may be &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;disadvantaged if it is prohibited from executing a trade outside the daily permissible price movement. At or prior to &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;maturity of a futures contract, the Fund may enter into an offsetting contract and may incur a loss to the extent there &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;has been adverse movement in futures contract prices. The liquidity of the futures markets depends on participants &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;entering into offsetting transactions rather than making or taking delivery. To the extent participants make or take &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;delivery, liquidity in the futures market could be reduced. Because of the low margin deposits normally required in &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;futures trading, it is possible that the Fund may employ a high degree of leverage in the portfolio. As a result, a &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;relatively small price movement in a futures contract may result in substantial losses to the Fund, exceeding the &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;amount of the margin paid. For certain types of futures contracts, losses are potentially unlimited. Futures markets &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;are highly volatile&lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;,&lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt; and the use of futures may increase the volatility of the Fund&#x2019;s NAV. Futures contracts executed (if &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;any) on foreign exchanges may not provide the same protection as U.S. exchanges. Futures contracts can increase &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;the Fund&#x2019;s risk exposure to underlying references and their attendant risks, such as credit risk, market risk, foreign &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;currency risk and interest rate risk, while potentially exposing the Fund to correlation risk, counterparty risk, hedging &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;risk, inflation risk, leverage risk, liquidity risk, pricing risk and volatility risk.&lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

The ability of &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;the Fund to realize its investment objective will depend, in large part, on the extent to which the Underlying Funds &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;realize their investment objective. There is no guarantee that the Underlying Funds will achieve their respective &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;investment objectives. The Fund is exposed to the same risks as the Underlying Funds in direct proportion to the &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;allocation of its assets among the Underlying Funds. Therefore, to the extent that the Fund invests significantly in a &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;particular Underlying Fund, the Fund&#x2019;s performance would be significantly impacted by the performance of such &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;Underlying Fund. Generally, by investing in a combination of Underlying Funds, the Fund has exposure to the risks of &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;many areas of the market. By concentrating its investments in relatively few Underlying Funds, the Fund may have &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;more concentrated market exposures, subjecting the Fund to greater risk of loss should those markets decline or fail &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;to rise. The performance of Underlying Funds could be adversely affected if other entities that invest in the same &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;funds make relatively large investments or redemptions in such funds. The Fund, and its shareholders, indirectly bear &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;a portion of the expenses of any funds in which the Fund invests. Because the expenses and costs of each &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;Underlying Fund are shared by its investors, redemptions by other investors in an Underlying Fund could result in &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;decreased economies of scale and increased operating expenses for such Underlying Fund. The Investment &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;Manager has a conflict of interest in choosing affiliated funds over unaffiliated funds when selecting and investing in &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;Underlying Funds because it receives management fees from affiliated funds, and it has a conflict in choosing &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;among affiliated funds when selecting and investing in Underlying Funds, because the fees paid to it by certain &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;affiliated funds are higher than the fees paid by other affiliated funds. Also, to the extent that the Fund is &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;constrained/restricted from investing (or investing further) in a particular Underlying Fund for one or more reasons &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;(e.g., Underlying Fund capacity constraints or regulatory restrictions) or if the Fund chooses to sell its investment in &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;an Underlying Fund because of poor investment performance or for other reasons, the Fund may have to invest in &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;another fund(s), including less desirable funds &#x2013; from a strategy or investment performance standpoint &#x2013; which &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;could have a negative impact on Fund performance. In addition, Fund performance could be negatively impacted if &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;the Investment Manager is unable to identify an appropriate alternate fund(s) in a timely manner or at all.&lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

In general, if interest &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:12.0pt;text-align:left;"&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;liquidity of the Fund&#x2019;s investments in debt instruments. In general, the longer the maturity or duration of a debt &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;instrument, the greater its sensitivity to changes in interest rates. For example, a three-year duration means a bond is &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;expected to decrease in value by 3% if interest rates rise 1% and increase in value by 3% if interest rates fall 1%. &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;risk. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;Actions by governments and central banking authorities can result in increases or decreases in interest rates. Higher &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;periods of inflation could lead such authorities to raise interest rates. Such actions may negatively affect the value of &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;debt instruments held by the Fund, resulting in a negative impact on the Fund's performance and NAV. Any interest &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;rate increases could cause the value of the Fund&#x2019;s investments in debt instruments to decrease. Rising interest rates &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;advantageous to do so, which could result in losses.&lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

An investment in a money market fund, even an investment in a fund seeking to maintain &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;a stable NAV per share, is not guaranteed and it is possible for the Fund to lose money by investing in these and &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;other types of money market funds. Certain money market funds (including the Fund&#x2019;s cash sweep vehicle) are &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;subject to mandatory liquidity fees if daily net redemptions exceed 5% of their net assets and may also impose a &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;discretionary liquidity fee of up to 2% on redemptions if that fee is determined to be in the best interests of the &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;money market fund. Such fees, if imposed, will reduce the amount the Fund receives on redemptions. In addition to &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;the fees and expenses that the Fund directly bears, the Fund indirectly bears the fees and expenses of any money &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;market funds in which it invests, including affiliated money market funds. By investing in a money market fund, the &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;Fund will be exposed to the investment risks of the money market fund in direct proportion to such investment. To &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;the extent the Fund invests in instruments such as derivatives, the Fund may hold investments, which may be &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;significant, in money market fund shares to cover its obligations resulting from the Fund&lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;'&lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;s investments in such &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;instruments.

In the case of &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;prepayment risk, if the investment is converted, prepaid or redeemed before maturity, the portfolio managers may &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;not be able to invest the proceeds in other investments providing as high a level of income, resulting in a reduced &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;yield to the Fund. As interest rates decrease or spreads narrow on such investments, the likelihood of prepayment &lt;/span&gt;&lt;span style="color:#003c78;font-family:arial;font-size:10pt"&gt;increases.
