The Fund has wide flexibility in the relative weightings given &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;to each category. The Fund takes both long and short positions within and across each category, which the Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;expects to result in a lower correlation to the equity or fixed-income markets than if the Fund invested in either such &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;market in its entirety.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;In selecting investments, the Fund management team will identify global macro opportunities and position the Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;using a combination of individual securities and derivatives.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund uses a combination of a systematic (i.e., rule-based) investment process and a discretionary investment &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;process to allocate assets. The systematic process compares data across similar assets to rank expected return &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;opportunities and to appropriately scale the Fund&#x2019;s exposure. The discretionary process derives investment themes &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;based on research and analysis of macro-economic data and seeks exposures to these themes.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;With respect to its equity investments, the Fund may invest in individual equity securities to an unlimited extent. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Fund may invest in common stock, preferred stock, non-convertible preferred stock and depositary receipts. The Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;may invest in securities of both U.S. and non-U.S. issuers without limit, which can be U.S. dollar-based or non-U.S. &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;dollar-based and may be currency hedged or unhedged. The Fund may invest in securities of companies of any market &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;capitalization. The Fund may also invest in securities convertible into common stock.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;With respect to its fixed-income investments, the Fund may invest in individual fixed-income securities to an unlimited &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;extent. The Fund may invest in a portfolio of fixed-income securities such as corporate bonds and notes, commercial &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and residential mortgage-backed securities (bonds that are backed by a mortgage loan or pools of loans secured &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;either by commercial property or residential mortgages, as applicable), collateralized mortgage obligations (bonds that &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;are backed by cash flows from pools of mortgages and may have multiple classes with different payment rights and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;protections), collateralized debt obligations (&#x201c;CDOs&#x201d;), asset-backed securities, convertible securities, debt obligations &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;of governments and their sub-divisions (including those of non-U.S. governments), other floating or variable rate &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;obligations, municipal obligations and zero coupon debt securities. The Fund may also invest a significant portion of its &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;assets in non-investment grade bonds (&#x201c;junk&#x201d; bonds or distressed securities), non-investment grade bank loans, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;foreign bonds (both U.S. dollar- and non-U.S. dollar-denominated) and bonds of emerging market issuers. The Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;may invest in non-U.S. dollar-denominated bonds on a currency hedged or unhedged basis.&lt;/span&gt;&lt;/div&gt;  &lt;div style="line-height: 10.695pt; text-align: left;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;With respect to its cash investments, the Fund may hold high quality money market securities, including short term &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;U.S. Government securities, U.S. Government agency securities, securities issued by U.S. Government-sponsored &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;enterprises and U.S. Government instrumentalities, bank obligations, commercial paper, including asset-backed &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;commercial paper, corporate notes and repurchase agreements. The Fund may invest a significant portion of its &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;assets in money market funds, including those advised by BlackRock or its affiliates.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may invest in derivatives, including, but not limited to, interest rate, total return and credit default swaps, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;options, futures, options on futures and swaps and foreign currency transactions (including swaps), for hedging &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;purposes, as well as to increase the return on its portfolio investments. The Fund may seek to obtain market exposure &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may also use forward foreign &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;currency exchange contracts (obligations to buy or sell a currency at a set rate in the future) to hedge against &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;movement in the value of non-U.S. currencies.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may also invest in indexed and inverse floating rate securities.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may invest in U.S. and non-U.S. real estate investment trusts (&#x201c;REITs&#x201d;), structured products (including, but &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;not limited to, structured notes, credit linked notes and participation notes, or other instruments evidencing interests &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;in special purpose vehicles, trusts, or other entities that hold or represent interests in fixed-income securities) and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;floating rate securities (such as bank loans).&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may seek to provide exposure to the investment returns of real assets, that trade in the commodity markets &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;through investment in commodity-linked derivative instruments and investment vehicles, such as exchange-traded &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;funds, that invest in commodities and are designed to provide investment exposure to physical commodities. The Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;expects to gain exposure to commodity markets by investing up to 25% of its total assets, inclusive of leverage, in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;BlackRock Cayman Tactical Opportunities Fund, Ltd. (the &#x201c;Subsidiary&#x201d;), a wholly owned subsidiary of the Fund formed &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;in the Cayman Islands, which invests primarily in commodity-related instruments. The Subsidiary may also hold cash &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and invest in other instruments, including fixed income securities, either as investments or to serve as margin or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;collateral for the Subsidiary&#x2019;s derivative positions. The Subsidiary (unlike the Fund) may invest without limitation in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;commodity-related instruments. However, the Subsidiary is otherwise subject to the same fundamental, non-fundamental&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; and certain other investment restrictions as the Fund.&lt;/span&gt;&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Changes in an issuer&#x2019;s credit rating or the market&#x2019;s &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;perception of an issuer&#x2019;s creditworthiness may also affect the value of the Fund&#x2019;s investment in that issuer. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Interest Rate Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; The market value of bonds and other fixed-income securities changes in response to interest &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;will increase as interest rates fall and decrease as interest rates rise.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may be subject to a greater risk of rising interest rates during a period of low interest rates. For example, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;equal, the value of the Fund&#x2019;s investments would be expected to decrease by 10%. (Duration is a measure of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities with longer maturities. Fluctuations in the market price of the Fund&#x2019;s investments will not affect interest &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;income derived from instruments already owned by the Fund, but will be reflected in the Fund&#x2019;s net asset value. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;management.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;debt securities.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;These basic principles of bond prices also apply to U.S. Government securities. A security backed by the &#x201c;full faith &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and credit&#x201d; of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;value when interest rates change.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;scale, which may increase redemptions from funds that hold large amounts of fixed-income securities. Heavy &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;redemptions could cause the Fund to sell assets at inopportune times or at a loss or depressed value and could &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;hurt the Fund&#x2019;s performance.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Extension Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; When interest rates rise, certain obligations will be paid off by the obligor more slowly than &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;anticipated, causing the value of these obligations to fall.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Prepayment Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; When interest rates fall, certain obligations will be paid off by the obligor more quickly than &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt; </oef:RiskTextBlock>

An illiquid investment is any &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;calendar days or less without the sale or disposition significantly changing the market value of the investment. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Subsidiary will also limit its investment in illiquid investments to 15% of its net assets. In applying the illiquid &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investments restriction to the Fund, the Fund&#x2019;s investment in the Subsidiary is considered to be liquid. Liquid &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investments may become illiquid after purchase by the Fund, particularly during periods of market turmoil. There can &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;be no assurance that a security or instrument that is deemed to be liquid when purchased will continue to be liquid &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;for as long as it is held by the Fund, and any security or instrument held by the Fund may be deemed an illiquid &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investment pursuant to the Fund&#x2019;s liquidity risk management program. The Fund&#x2019;s illiquid investments may reduce &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the returns of the Fund because it may be difficult to sell the illiquid investments at an advantageous time or price. &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;In addition, if the Fund is limited in its ability to dispose of illiquid investments during periods when shareholders &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;are redeeming or selling their shares or the Fund&#x2019;s net assets otherwise shrink, the Fund will need to dispose of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;liquid securities to meet redemption requests and illiquid securities will become a larger portion of the Fund&#x2019;s &lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt;  &lt;div style="line-height: 10.695pt; margin-left: 12pt; text-align: left;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;holdings. An investment may be illiquid due to, among other things, the reduced number and capacity of traditional &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;market participants to make a market in fixed-income securities or the lack of an active trading market. To the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;extent that the Fund&#x2019;s principal investment strategies involve derivatives or securities with substantial market and/or&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; credit risk, the Fund will tend to have greater exposure to the risks associated with illiquid investments. Illiquid &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investments may be harder to value, especially in changing markets, and if the Fund is forced to sell these &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investments to meet redemption requests or for other cash needs, the Fund may suffer a loss. This may be &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;magnified in a rising interest rate environment or other circumstances where investor redemptions or sales of Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;shares may be higher than normal. In addition, when there is illiquidity in the market for certain securities, the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Fund, due to limitations on illiquid investments, may be subject to purchase and sale restrictions.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt; </oef:RiskTextBlock>

The value of inflation-indexed &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities generally fluctuates with changes in real interest rates, decreasing when real interest rates rise and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;increasing when real interest rates fall. Real interest rates represent nominal (or stated) interest rates minus the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;inflation rates. If the Fund purchases TIPS in the secondary market and the bonds&#x2019; principal values previously were &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;adjusted upward, but then there is a period of declining inflation rates, the Fund may receive at maturity less than it &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;invested.&lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;In addition, interest payments on inflation-indexed securities generally vary up or down along with the rate of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;inflation, and inflation-indexed bonds typically have lower nominal yields than conventional fixed-rate bonds. If the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;reduced.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Any increase in the principal amount of an inflation-indexed bond will be considered taxable ordinary income, even &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;though investors do not receive their principal until maturity. Periodic adjustments for inflation to the principal &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;amount of an inflation-indexed bond may give rise to original issue discount, which will be includable in the Fund&#x2019;s &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;gross income. Due to original issue discount, the Fund may be required to make annual distributions to &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;shareholders that exceed the cash received, which may cause the Fund to liquidate certain investments when it is &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;not advantageous to do so.

Preferred securities &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;are subject to issuer-specific and market risks applicable generally to equity securities. In addition, a company&#x2019;s &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;preferred securities generally pay dividends only after the company makes required payments to holders of its &lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt;  &lt;div style="line-height: 10.695pt; margin-left: 12pt; text-align: left;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;bonds and other debt.

Many factors may affect real estate values. These factors include both the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re-lease &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;property type, the Fund will be particularly subject to the risks associated with that area or property type. Many &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;commenced development on properties and may develop additional properties in the future. Real estate &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;development involves significant risks in addition to those involved in the ownership and operation of established &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;dependency and defaults by borrowers or tenants.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt; </oef:RiskTextBlock>

An economic downturn generally leads to a higher non-payment rate, and a senior &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;loan may lose significant value before a default occurs. Moreover, any specific collateral used to secure a senior &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;loan may decline in value or become illiquid, which would adversely affect the senior loan&#x2019;s value. No active trading &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;of the need to sell a senior loan and which may make it difficult to value senior loans. Although senior loans in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;which the Fund will invest generally will be secured by specific collateral, there can be no assurance that liquidation &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;of such collateral would satisfy the borrower&#x2019;s obligation in the event of non-payment of scheduled interest or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;principal or that such collateral could be readily liquidated. To the extent that a senior loan is collateralized by stock &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;in the borrower or its subsidiaries, such stock may lose all of its value in the event of the bankruptcy of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;borrower. Uncollateralized senior loans involve a greater risk of loss. The senior loans in which the Fund invests are &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;usually rated below investment grade.&lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt; </oef:RiskTextBlock>

The Fund may have the right to receive &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;payments only from the structured security, and generally does not have direct rights against the issuer or the entity &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;that sold the assets to be securitized. In addition to the general risks associated with debt securities discussed &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;herein, structured securities carry additional risks, including, but not limited to: the possibility that distributions &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;from collateral securities will not be adequate to make interest or other payments; the quality of the collateral may &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;decline in value or default; and the possibility that the structured securities are subordinate to other classes. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Fund is permitted to invest in a class of structured securities that is either subordinated or unsubordinated to the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;right of payment of another class. Subordinated structured securities typically have higher yields and present &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;greater risks than unsubordinated structured securities. Structured securities are typically sold in private placement &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;transactions, and there currently is no active trading market for structured securities. Structured securities are &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;based upon the movement of one or more factors, including currency exchange rates, interest rates, reference &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;bonds and stock indices, and changes in interest rates and impact of these factors may cause significant price &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;fluctuations. Additionally, changes in the reference instrument or security may cause the interest rate on the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;structured security to be reduced to zero. Certain issuers of such structured securities may be deemed to be &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;&#x201c;investment companies&#x201d; as defined in the Investment Company Act.

An investment in a tender option bond transaction typically will involve &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;greater risk than an investment in a municipal fixed rate security, including the risk of loss of principal.

The Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;may invest in securities of both U.S. and non-U.S. issuers without limit, which can be U.S. dollar-based or non-U.S. &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;dollar-based and may be currency hedged or unhedged.

The Fund may invest in a portfolio of fixed-income securities such as corporate bonds and notes, commercial &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and residential mortgage-backed securities (bonds that are backed by a mortgage loan or pools of loans secured &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;either by commercial property or residential mortgages, as applicable), collateralized mortgage obligations (bonds that &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;are backed by cash flows from pools of mortgages and may have multiple classes with different payment rights and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;protections), collateralized debt obligations (&#x201c;CDOs&#x201d;), asset-backed securities, convertible securities, debt obligations &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;of governments and their sub-divisions (including those of non-U.S. governments), other floating or variable rate &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;obligations, municipal obligations and zero coupon debt securities. The Fund may also invest a significant portion of its &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;assets in non-investment grade bonds (&#x201c;junk&#x201d; bonds or distressed securities), non-investment grade bank loans, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;foreign bonds (both U.S. dollar- and non-U.S. dollar-denominated) and bonds of emerging market issuers. The Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;may invest in non-U.S. dollar-denominated bonds on a currency hedged or unhedged basis.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;With respect to its cash investments, the Fund may hold high quality money market securities, including short term &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;U.S. Government securities, U.S. Government agency securities, securities issued by U.S. Government-sponsored &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;enterprises and U.S. Government instrumentalities, bank obligations, commercial paper, including asset-backed &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;commercial paper, corporate notes and repurchase agreements. The Fund may invest a significant portion of its &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;assets in money market funds, including those advised by BlackRock or its affiliates.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may invest in derivatives, including, but not limited to, interest rate, total return and credit default swaps, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;options, futures, options on futures and swaps and foreign currency transactions (including swaps), for hedging &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;purposes, as well as to increase the return on its portfolio investments. The Fund may seek to obtain market exposure &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may also use forward foreign &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;currency exchange contracts (obligations to buy or sell a currency at a set rate in the future) to hedge against &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;movement in the value of non-U.S. currencies.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may also invest in indexed and inverse floating rate securities.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may invest in U.S. and non-U.S. real estate investment trusts (&#x201c;REITs&#x201d;), structured products (including, but &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;not limited to, structured notes, credit linked notes and participation notes, or other instruments evidencing interests &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;in special purpose vehicles, trusts, or other entities that hold or represent interests in fixed-income securities) and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;floating rate securities (such as bank loans).&lt;/span&gt;&lt;/div&gt;  &lt;div style="line-height: 10.695pt; text-align: left;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may seek to provide exposure to the investment returns of real assets, that trade in the commodity markets &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;through investment in commodity-linked derivative instruments and investment vehicles, such as exchange-traded &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;funds, that invest in commodities and are designed to provide investment exposure to physical commodities. The Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;expects to gain exposure to commodity markets by investing up to 25% of its total assets, inclusive of leverage, in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;BlackRock Cayman Tactical Opportunities Fund, Ltd.

The Subsidiary may also hold cash &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and invest in other instruments, including fixed income securities, either as investments or to serve as margin or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;collateral for the Subsidiary&#x2019;s derivative positions. The Subsidiary (unlike the Fund) may invest without limitation in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;commodity-related instruments. However, the Subsidiary is otherwise subject to the same fundamental, non-fundamental&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; and certain other investment restrictions as the Fund.&lt;/span&gt;&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Interest Rate Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; The market value of bonds and other fixed-income securities changes in response to interest &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;will increase as interest rates fall and decrease as interest rates rise.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may be subject to a greater risk of rising interest rates during a period of low interest rates. For example, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;equal, the value of the Fund&#x2019;s investments would be expected to decrease by 10%. (Duration is a measure of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities with longer maturities. Fluctuations in the market price of the Fund&#x2019;s investments will not affect interest &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;income derived from instruments already owned by the Fund, but will be reflected in the Fund&#x2019;s net asset value. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;management.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;debt securities.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;These basic principles of bond prices also apply to U.S. Government securities. A security backed by the &#x201c;full faith &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and credit&#x201d; of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;value when interest rates change.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;scale, which may increase redemptions from funds that hold large amounts of fixed-income securities. Heavy &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;redemptions could cause the Fund to sell assets at inopportune times or at a loss or depressed value and could &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;hurt the Fund&#x2019;s performance.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Extension Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; When interest rates rise, certain obligations will be paid off by the obligor more slowly than &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;anticipated, causing the value of these obligations to fall.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Prepayment Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; When interest rates fall, certain obligations will be paid off by the obligor more quickly than &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt; </oef:RiskTextBlock>

An illiquid investment is any &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;calendar days or less without the sale or disposition significantly changing the market value of the investment. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Subsidiary will also limit its investment in illiquid investments to 15% of its net assets. In applying the illiquid &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investments restriction to the Fund, the Fund&#x2019;s investment in the Subsidiary is considered to be liquid. Liquid &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investments may become illiquid after purchase by the Fund, particularly during periods of market turmoil. There can &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;be no assurance that a security or instrument that is deemed to be liquid when purchased will continue to be liquid &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;for as long as it is held by the Fund, and any security or instrument held by the Fund may be deemed an illiquid &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investment pursuant to the Fund&#x2019;s liquidity risk management program. The Fund&#x2019;s illiquid investments may reduce &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the returns of the Fund because it may be difficult to sell the illiquid investments at an advantageous time or price. &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;In addition, if the Fund is limited in its ability to dispose of illiquid investments during periods when shareholders &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;are redeeming or selling their shares or the Fund&#x2019;s net assets otherwise shrink,, the Fund will need to dispose of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;liquid securities to meet redemption requests and illiquid securities will become a larger portion of the Fund&#x2019;s &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;holdings. An investment may be illiquid due to, among other things, the reduced number and capacity of traditional &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;market participants to make a market in fixed-income securities or the lack of an active trading market. To the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;extent that the Fund&#x2019;s principal investment strategies involve derivatives or securities with substantial market and/&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;or credit risk, the Fund will tend to have greater exposure to the risks associated with illiquid investments. Illiquid &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investments may be harder to value, especially in changing markets, and if the Fund is forced to sell these &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investments to meet redemption requests or for other cash needs, the Fund may suffer a loss. This may be &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;magnified in a rising interest rate environment or other circumstances where investor redemptions or sales of Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;shares may be higher than normal. In addition, when there is illiquidity in the market for certain securities, the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Fund, due to limitations on illiquid investments, may be subject to purchase and sale restrictions.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt; </oef:RiskTextBlock>

Real interest rates represent nominal (or stated) interest rates minus the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;inflation rates. If the Fund purchases TIPS in the secondary market and the bonds&#x2019; principal values previously were &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;adjusted upward, but then there is a period of declining inflation rates, the Fund may receive at maturity less than it &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;invested.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;In addition, interest payments on inflation-indexed securities generally vary up or down along with the rate of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;inflation, and inflation-indexed bonds typically have lower nominal yields than conventional fixed-rate bonds. If the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;reduced.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Any increase in the principal amount of an inflation-indexed bond will be considered taxable ordinary income, even &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;though investors do not receive their principal until maturity. Periodic adjustments for inflation to the principal &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;amount of an inflation-indexed bond may give rise to original issue discount, which will be includable in the Fund&#x2019;s &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;gross income.

Also, if the principal value of an inflation-indexed bond is adjusted downward due to &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;deflation, amounts previously distributed in the taxable year may be characterized in some circumstances as a &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;return of capital.&lt;/span&gt;&lt;/div&gt; </oef:RiskTextBlock>

Many factors may affect real estate values. These factors include both the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re-lease &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;property type, the Fund will be particularly subject to the risks associated with that area or property type. Many &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;commenced development on properties and may develop additional properties in the future. Real estate &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;development involves significant risks in addition to those involved in the ownership and operation of established &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in &lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt;  &lt;div style="line-height: 10.695pt; margin-left: 12pt; text-align: left;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;operating and financing a limited number of projects.

An economic downturn generally leads to a higher non-payment rate, and a senior &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;loan may lose significant value before a default occurs. Moreover, any specific collateral used to secure a senior &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;loan may decline in value or become illiquid, which would adversely affect the senior loan&#x2019;s value. No active trading &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;of the need to sell a senior loan and which may make it difficult to value senior loans. Although senior loans in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;which the Fund will invest generally will be secured by specific collateral, there can be no assurance that liquidation &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;of such collateral would satisfy the borrower&#x2019;s obligation in the event of non-payment of scheduled interest or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;principal or that such collateral could be readily liquidated. To the extent that a senior loan is collateralized by stock &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;in the borrower or its subsidiaries, such stock may lose all of its value in the event of the bankruptcy of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;borrower. Uncollateralized senior loans involve a greater risk of loss. The senior loans in which the Fund invests are &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;usually rated below investment grade.&lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt; </oef:RiskTextBlock>

The Fund may have the right to receive &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;payments only from the structured security, and generally does not have direct rights against the issuer or the entity &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;that sold the assets to be securitized. In addition to the general risks associated with debt securities discussed &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;herein, structured securities carry additional risks, including, but not limited to: the possibility that distributions &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;from collateral securities will not be adequate to make interest or other payments; the quality of the collateral may &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;decline in value or default; and the possibility that the structured securities are subordinate to other classes. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Fund is permitted to invest in a class of structured securities that is either subordinated or unsubordinated to the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;right of payment of another class. Subordinated structured securities typically have higher yields and present &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;greater risks than unsubordinated structured securities. Structured securities are typically sold in private placement &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;transactions, and there currently is no active trading market for structured securities. Structured securities are &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;based upon the movement of one or more factors, including currency exchange rates, interest rates, reference &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;bonds and stock indices, and changes in interest rates and impact of these factors may cause significant price &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;fluctuations. Additionally, changes in the reference instrument or security may cause the interest rate on the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;structured security to be reduced to zero. Certain issuers of such structured securities may be deemed to be &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;&#x201c;investment companies&#x201d; as defined in the Investment Company Act.

Securities with floating or variable interest rates can be less sensitive to &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;interest rate changes than securities with fixed interest rates, but may decline in value if their coupon rates do not &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;reset as high, or as quickly, as comparable market interest rates, and generally carry lower yields than fixed &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities of the same maturity. These securities will not generally increase in value if interest rates decline. A &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;decline in interest rates may result in a reduction in income received from variable and floating rate securities held &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;by the Fund and may adversely affect the value of the Fund&#x2019;s shares.

Floating rate securities generally are &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the Fund needs to liquidate such loans. Benchmark interest rates may not accurately track market interest rates. &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Although floating rate securities are less sensitive to interest rate risk than fixed-rate securities, they are subject to &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;credit risk and default risk, which could impair their value.&lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt; </oef:RiskTextBlock>

The effect of owning instruments that do not make current interest payments is that a fixed yield &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;is earned not only on the original investment but also, in effect, on all discount accretion during the life of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;obligations. This implicit reinvestment of earnings at a fixed rate eliminates the risk of being unable to invest &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;distributions at a rate as high as the implicit yield on the zero coupon bond, but at the same time eliminates the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;holder&#x2019;s ability to reinvest at higher rates in the future. For this reason, some of these securities may be subject to &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;substantially greater price fluctuations during periods of changing market interest rates than are comparable &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities that pay interest currently.

The Fund may also use forward foreign &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;currency exchange contracts (obligations to buy or sell a currency at a set rate in the future) to hedge against &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;movement in the value of non-U.S. currencies.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may also invest in indexed and inverse floating rate securities.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may invest in U.S. and non-U.S. real estate investment trusts (&#x201c;REITs&#x201d;), structured products (including, but &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;not limited to, structured notes, credit linked notes and participation notes, or other instruments evidencing interests &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;in special purpose vehicles, trusts, or other entities that hold or represent interests in fixed-income securities) and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;floating rate securities (such as bank loans).&lt;/span&gt;&lt;/div&gt;  &lt;div style="line-height: 10.695pt; text-align: left;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may seek to provide exposure to the investment returns of real assets, that trade in the commodity markets &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;through investment in commodity-linked derivative instruments and investment vehicles, such as exchange-traded &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;funds, that invest in commodities and are designed to provide investment exposure to physical commodities. The Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;expects to gain exposure to commodity markets by investing up to 25% of its total assets, inclusive of leverage, in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;BlackRock Cayman Tactical Opportunities Fund, Ltd. (the &#x201c;Subsidiary&#x201d;), a wholly owned subsidiary of the Fund formed &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;in the Cayman Islands, which invests primarily in commodity-related instruments. The Subsidiary may also hold cash &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and invest in other instruments, including fixed income securities, either as investments or to serve as margin or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;collateral for the Subsidiary&#x2019;s derivative positions. The Subsidiary (unlike the Fund) may invest without limitation in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;commodity-related instruments. However, the Subsidiary is otherwise subject to the same fundamental, non-fundamental&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; and certain other investment restrictions as the Fund.&lt;/span&gt;&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Interest Rate Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; The market value of bonds and other fixed-income securities changes in response to interest &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;will increase as interest rates fall and decrease as interest rates rise.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may be subject to a greater risk of rising interest rates during a period of low interest rates. For example, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;equal, the value of the Fund&#x2019;s investments would be expected to decrease by 10%. (Duration is a measure of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities with longer maturities. Fluctuations in the market price of the Fund&#x2019;s investments will not affect interest &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;income derived from instruments already owned by the Fund, but will be reflected in the Fund&#x2019;s net asset value. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;management.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;debt securities.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;These basic principles of bond prices also apply to U.S. Government securities. A security backed by the &#x201c;full faith &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and credit&#x201d; of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;value when interest rates change.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;scale, which may increase redemptions from funds that hold large amounts of fixed-income securities. Heavy &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;redemptions could cause the Fund to sell assets at inopportune times or at a loss or depressed value and could &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;hurt the Fund&#x2019;s performance.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Extension Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; When interest rates rise, certain obligations will be paid off by the obligor more slowly than &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;anticipated, causing the value of these obligations to fall.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Prepayment Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; When interest rates fall, certain obligations will be paid off by the obligor more quickly than &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

Therefore, there may be less information available regarding these &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;issuers and there may not be a correlation between such information and the market value of the depositary &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;receipts. While depositary receipts provide an alternative to directly purchasing underlying foreign securities in their &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;respective markets and currencies, they continue to be subject to many of the risks associated with investing &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;directly in foreign securities, including political, economic, and currency risk.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt;</oef:RiskTextBlock>

An illiquid investment is any &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;calendar days or less without the sale or disposition significantly changing the market value of the investment. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Subsidiary will also limit its investment in illiquid investments to 15% of its net assets. In applying the illiquid &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investments restriction to the Fund, the Fund&#x2019;s investment in the Subsidiary is considered to be liquid. Liquid &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investments may become illiquid after purchase by the Fund, particularly during periods of market turmoil. There can &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;be no assurance that a security or instrument that is deemed to be liquid when purchased will continue to be liquid &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;for as long as it is held by the Fund, and any security or instrument held by the Fund may be deemed an illiquid &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investment pursuant to the Fund&#x2019;s liquidity risk management program. The Fund&#x2019;s illiquid investments may reduce &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the returns of the Fund because it may be difficult to sell the illiquid investments at an advantageous time or price. &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;In addition, if the Fund is limited in its ability to dispose of illiquid investments during periods when shareholders &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;are redeeming or selling their shares or the Fund&#x2019;s net assets otherwise shrink,, the Fund will need to dispose of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;liquid securities to meet redemption requests and illiquid securities will become a larger portion of the Fund&#x2019;s &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;holdings. An investment may be illiquid due to, among other things, the reduced number and capacity of traditional &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;market participants to make a market in fixed-income securities or the lack of an active trading market. To the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;extent that the Fund&#x2019;s principal investment strategies involve derivatives or securities with substantial market and/&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;or credit risk, the Fund will tend to have greater exposure to the risks associated with illiquid investments. Illiquid &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investments may be harder to value, especially in changing markets, and if the Fund is forced to sell these &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investments to meet redemption requests or for other cash needs, the Fund may suffer a loss. This may be &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;magnified in a rising interest rate environment or other circumstances where investor redemptions or sales of Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;shares may be higher than normal. In addition, when there is illiquidity in the market for certain securities, the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Fund, due to limitations on illiquid investments, may be subject to purchase and sale restrictions.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt;</oef:RiskTextBlock>

Real interest rates represent nominal (or stated) interest rates minus the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;inflation rates. If the Fund purchases TIPS in the secondary market and the bonds&#x2019; principal values previously were &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;adjusted upward, but then there is a period of declining inflation rates, the Fund may receive at maturity less than it &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;invested.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;In addition, interest payments on inflation-indexed securities generally vary up or down along with the rate of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;inflation, and inflation-indexed bonds typically have lower nominal yields than conventional fixed-rate bonds. If the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;reduced.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Any increase in the principal amount of an inflation-indexed bond will be considered taxable ordinary income, even &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;though investors do not receive their principal until maturity. Periodic adjustments for inflation to the principal &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;amount of an inflation-indexed bond may give rise to original issue discount, which will be includable in the Fund&#x2019;s &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;gross income. Due to original issue discount, the Fund may be required to make annual distributions to &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;shareholders that exceed the cash received, which may cause the Fund to liquidate certain investments when it is &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;not advantageous to do so. Also, if the principal value of an inflation-indexed bond is adjusted downward due to &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;deflation, amounts previously distributed in the taxable year may be characterized in some circumstances as a &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;return of capital.&lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

Many factors may affect real estate values. These factors include both the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re-lease &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;property type, the Fund will be particularly subject to the risks associated with that area or property type. Many &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;commenced development on properties and may develop additional properties in the future. Real estate &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;development involves significant risks in addition to those involved in the ownership and operation of established &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in &lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt;&lt;div style="line-height: 10.695pt; margin-left: 12pt; text-align: left;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;operating and financing a limited number of projects.

In &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;addition, if the loan is foreclosed, the Fund could become part owner of any collateral and could bear the costs and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;liabilities of owning and disposing of the collateral.

An economic downturn generally leads to a higher non-payment rate, and a senior &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;loan may lose significant value before a default occurs. Moreover, any specific collateral used to secure a senior &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;loan may decline in value or become illiquid, which would adversely affect the senior loan&#x2019;s value. No active trading &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;of the need to sell a senior loan and which may make it difficult to value senior loans. Although senior loans in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;which the Fund will invest generally will be secured by specific collateral, there can be no assurance that liquidation &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;of such collateral would satisfy the borrower&#x2019;s obligation in the event of non-payment of scheduled interest or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;principal or that such collateral could be readily liquidated. To the extent that a senior loan is collateralized by stock &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;in the borrower or its subsidiaries, such stock may lose all of its value in the event of the bankruptcy of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;borrower. Uncollateralized senior loans involve a greater risk of loss. The senior loans in which the Fund invests are &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;usually rated below investment grade.&lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt;</oef:RiskTextBlock>

The purchase of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;structured notes exposes the Fund to the credit risk of the issuer of the structured product.

The Fund may have the right to receive &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;payments only from the structured security, and generally does not have direct rights against the issuer or the entity &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;that sold the assets to be securitized. In addition to the general risks associated with debt securities discussed &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;herein, structured securities carry additional risks, including, but not limited to: the possibility that distributions &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;from collateral securities will not be adequate to make interest or other payments; the quality of the collateral may &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;decline in value or default; and the possibility that the structured securities are subordinate to other classes. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Fund is permitted to invest in a class of structured securities that is either subordinated or unsubordinated to the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;right of payment of another class. Subordinated structured securities typically have higher yields and present &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;greater risks than unsubordinated structured securities. Structured securities are typically sold in private placement &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;transactions, and there currently is no active trading market for structured securities. Structured securities are &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;based upon the movement of one or more factors, including currency exchange rates, interest rates, reference &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;bonds and stock indices, and changes in interest rates and impact of these factors may cause significant price &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;fluctuations. Additionally, changes in the reference instrument or security may cause the interest rate on the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;structured security to be reduced to zero. Certain issuers of such structured securities may be deemed to be &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;&#x201c;investment companies&#x201d; as defined in the Investment Company Act. As a result, the Fund&#x2019;s investment in such &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities may be limited by certain investment restrictions contained in the Investment Company Act.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt;</oef:RiskTextBlock>

The commodity-related instruments held by the Subsidiary are generally similar to those &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;that are permitted to be held by the Fund and are subject to the same risks that apply to similar investments if held &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;directly by the Fund (see &#x201c;Commodities Related Investments Risk&#x201d; above). There can be no assurance that the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the Investment &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Company Act, and, unless otherwise noted in this prospectus, is not subject to all the investor protections of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Investment Company Act. However, the Fund wholly owns and controls the Subsidiary, and the Fund and the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Subsidiary are both managed by BlackRock, making it unlikely that the Subsidiary will take action contrary to the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;interests of the Fund and its shareholders. The Board has oversight responsibility for the investment activities of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the Fund, including its investment in the Subsidiary, and the Fund&#x2019;s role as sole shareholder of the Subsidiary. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Subsidiary is subject to the same investment restrictions and limitations, and follows the same compliance policies &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and procedures, as the Fund except that the Subsidiary may invest without limitation in commodity-related &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;instruments.

Distributions &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;on residual inverse floating rate interests (&#x201c;TOB Residuals&#x201d;) will bear an inverse relationship to short-term municipal &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;security interest rates.

Securities with floating or variable interest rates can be less sensitive to &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;interest rate changes than securities with fixed interest rates, but may decline in value if their coupon rates do not &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;reset as high, or as quickly, as comparable market interest rates, and generally carry lower yields than fixed &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities of the same maturity. These securities will not generally increase in value if interest rates decline. A &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;decline in interest rates may result in a reduction in income received from variable and floating rate securities held &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;by the Fund and may adversely affect the value of the Fund&#x2019;s shares. These securities may be subject to greater &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;illiquidity risk than other fixed income securities, meaning the absence of an active market for these securities &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;could make it difficult for the Fund to dispose of them at any given time. Floating rate securities generally are &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the Fund needs to liquidate such loans. Benchmark interest rates may not accurately track market interest rates. &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Although floating rate securities are less sensitive to interest rate risk than fixed-rate securities, they are subject to &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;credit risk and default risk, which could impair their value.&lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt;</oef:RiskTextBlock>

The effect of owning instruments that do not make current interest payments is that a fixed yield &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;is earned not only on the original investment but also, in effect, on all discount accretion during the life of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;obligations. This implicit reinvestment of earnings at a fixed rate eliminates the risk of being unable to invest &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;distributions at a rate as high as the implicit yield on the zero coupon bond, but at the same time eliminates the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;holder&#x2019;s ability to reinvest at higher rates in the future. For this reason, some of these securities may be subject to &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;substantially greater price fluctuations during periods of changing market interest rates than are comparable &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities that pay interest currently. Longer term zero coupon bonds are more exposed to interest rate risk than &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;shorter term zero coupon bonds.

Such indices use withholding tax rates that are often at a higher rate than the rates to which the Fund is subject in each country, including for countries where the Fund is not subject to withholding taxes. When this is the case, index performance will be lower than if the index used the Fund&#x2019;s applicable withholding tax rates, if any.</link:footnote>
