The Fund's concentration in these companies may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. A downturn in these companies would have a larger impact on the Fund than on a mutual fund that does not concentrate in such companies.

If the Fund concentrates its investments in this manner, it assumes the risk that economic, political and social conditions in those countries will have a significant impact on its investment performance. The Fund's investment performance may also be more volatile if it concentrates its investments in certain countries, especially emerging market countries. </li> <li><b><i>Investment Style Risk </i></b>&#8212; Under certain market conditions, growth investments have performed better during the later stages of economic expansion. Therefore, this investment style may over time go in and out of favor. At times when the investment style used by the Fund is out of favor, the Fund may underperform other equity funds that use different investment styles.</li> <li><b><i>Market Risk and Selection Risk </i></b>&#8212; Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Selection risk is the risk that the securities selected by Fund management will underperform the markets, the relevant indices or the securities selected by other funds with similar investment objectives and investment strategies. This means you may lose money.</li> <li><b><i>Mid</i><i>Cap Securities Risk </i></b>&#8212; The securities of mid-cap companies generally trade in lower volumes and are generally subject to greater and less predictable price changes than the securities of larger capitalization companies. </li> <li><b><i>"New Issues" Risk </i></b>&#8212; "New Issues" are initial public offerings of U.S. equity securities. Securities issued in IPOs have no trading history, and information about the companies may be available for very limited periods. In addition, the prices of securities sold in IPOs may be highly volatile or may decline shortly after the initial public offering. </li> <li><b><i>Small Cap Securities Risk </i></b>&#8212; Small cap companies may have limited product lines or markets. They may be less financially secure than larger, more established companies. They may depend on a more limited management group than larger capitalized companies. </li> <li><b><i>Technology Securities Risk </i></b>&#8212; Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. </li></ul></div> </div> <div class="MetaData"><font class="_mt" size="5">Fund Overview</font> <p style="text-align: left;"><b><a name="pro1p14"> </a>Key Facts About BlackRock U.S. Opportunities Portfolio</b></p></div> <div class="MetaData"> <div><font class="_mt" size="5">Fund Overview</font> <p style="text-align: left;"><b><a name="pro1p24"> </a>Key Facts About BlackRock Science &amp; Technology Opportunities Portfolio</b></p></div></div> <div class="MetaData"> <p style="line-height: normal; margin: 0in 0in 0pt; font-family: 'Calibri','sans-serif'; font-size: 11pt;" class="MsoNormal"><font style="font-family: 'Arial','sans-serif'; font-size: 13.5pt;" class="_mt">Fund Overview</font><font style="font-family: 'Arial','sans-serif'; font-size: 10pt;" class="_mt"> </font></p> <p style="line-height: normal; margin: 0in 0in 0pt; font-family: 'Calibri','sans-serif'; font-size: 11pt;" class="MsoNormal">&nbsp;</p> <div style="text-align: center; line-height: normal; margin: 0in 0in 0pt; font-family: 'Calibri','sans-serif'; font-size: 11pt;" class="MsoNormal" align="center"><font style="font-family: 'Arial','sans-serif'; font-size: 10pt;" class="_mt"> </font></div> <p style="line-height: normal; margin: 0in 0in 10pt; font-family: 'Calibri','sans-serif'; font-size: 11pt;" class="MsoNormal"><a name="PRO-OPP-SVC_17"> </a><b><font style="font-family: 'Arial','sans-serif'; font-size: 10pt;" class="_mt">Key Facts About BlackRock Science &amp; Technology Opportunities Portfolio</font></b><font style="font-family: 'Arial','sans-serif'; font-size: 10pt;" class="_mt"> </font></p></div> <div class="MetaData"> <div><strong>Shareholder Fees</strong></div> <div><strong>(fees paid directly from your investment)</strong></div></div> <div class="MetaData"> <div> <p style="margin-top: 0px; margin-bottom: 0px;"><strong><font class="_mt" size="2">Shareholder Fees</font></strong></p> <p style="margin-top: 0px; margin-bottom: 0px;"><font class="_mt" size="2">&nbsp;<strong>(fees paid directly from your investment)</strong></font></p></div></div> <div class="MetaData"> <p style="margin-top: 0px; margin-bottom: 0px;"><font class="_mt"><font class="_mt"><font size="2" class="_mt"><strong>Shareholder Fees</strong></font></font></font></p> <p style="margin-top: 0px; margin-bottom: 0px;"><font class="_mt"><font size="2" class="_mt"><font class="_mt">&nbsp;</font><strong><font class="_mt">(fees paid directly from your investment</font>)</strong></font></font></p></div> <div> &lt;div style="display:none;" &gt;~ http://www.blackrock.com/role/ScheduleShareholderFeesUSOpportunitiesPortfolioInvInst column period compact * column dei_LegalEntityAxis compact cik000844779_S000001509Member column rr_ProspectusShareClassAxis compact * row primary compact * ~&lt;/div&gt; </div> <div> &lt;div style="display:none;" &gt;~ http://www.blackrock.com/role/ScheduleShareholderFeesScienceTechnologyOpportunitiesPortfolioInvInst column period compact * column dei_DocumentInformationDocumentAxis compact cik000844779_InvInstMember column dei_LegalEntityAxis compact cik000844779_S000001510Member column rr_ProspectusShareClassAxis compact * row primary compact * ~&lt;/div&gt; </div> <div> &lt;div style="display:none;" &gt;~ http://www.blackrock.com/role/ScheduleShareholderFeesScienceTechnologyOpportunitiesPortfolioServiceShares column period compact * column dei_DocumentInformationDocumentAxis compact cik000844779_ServiceSharesMember column dei_LegalEntityAxis compact cik000844779_S000001510Member column rr_ProspectusShareClassAxis compact * row primary compact * ~&lt;/div&gt; </div> <font class="_mt"><b><i>Principal Investment Strategies of the Fund</i></b></font> <div style="font-family: 'Arial'; font-size: 10pt;"><b><i>Principal Investment Strategies of the Fund</i></b> </div> <font class="_mt"><b><i>Principal Investment Strategies of the Fund</i></b></font> <div> <div class="MetaData"> <p style="text-align: left;"><font class="_mt">Under normal market conditions, U.S. Opportunities invests at least 80% of its net assets in equity securities issued by U.S. emerging capitalization companies with relatively attractive earnings growth potential and valuation. </font>Although a universal definition of emerging capitalization companies does not exist, the Fund generally defines these companies, at the time of the Fund's investment, as those with market capitalizations equal to those within the universe of Russell Midcap<font class="_mt" size="1"><sup>&#174;</sup></font> Index stocks (between approximately $968 million and $13.668 billion as of June 30, 2010, the most recent rebalance date).

A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when shares are held in a taxable account.

<p style="text-align: left;"><font class="_mt">Under normal market conditions, Science &amp; Technology Opportunities invests at least 80% of its net assets in equity securities issued by U.S. and non-U.S. science and technology companies in all market capitalization ranges, selected for their rapid and sustainable growth potential from the development, advancement and use of science and/or use of technology. </font>The Fund may invest up to 25% of its net assets in emerging market countries.</p>

<p style="text-align: left;">Some of the industries likely to be represented in the Fund's portfolio holdings include: application software, IT consulting and services, internet software and services, networking equipment, telecom equipment, computer hardware, computer storage and peripherals, electronic equipment and instruments, semiconductors and equipment, aerospace and defense, electrical components and equipment, biotechnology, pharmaceuticals, healthcare equipment and supplies, healthcare distribution and services, healthcare facilities, industrial gases, specialty chemicals, advanced materials, integrated telecom services, alternative carriers and wireless telecommunication services.</p>

<p style="text-align: left;">The Fund primarily invests in common stock but may also invest in preferred stock and convertible securities. The Fund may also invest in Rule 144A securities, which are privately placed securities purchased by qualified institutional buyers. From time to time the Fund may invest in shares of companies through initial public offerings ("IPOs").</p>

<p style="text-align: left;">The Fund may, when consistent with the Fund's investment goal, buy or sell options or futures on a security or an index of securities and may buy options on a currency or a basket of currencies, or enter into foreign currency transactions, including swaps (collectively, commonly known as derivatives). The Fund typically uses derivatives as a substitute for taking a position in the underlying asset and/or as part of a strategy designed to reduce exposure to other risks, such as currency risk. The Fund may also use derivatives to enhance returns, in which case their use would involve leveraging risk. The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may also use forward foreign currency exchange contracts (obligations to buy or sell a currency at a set rate in the future). T
he Fund may, but under normal market conditions generally does not intend to, use derivatives for speculation to increase returns.</p> </div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

<div style="font-family: 'arial'; font-size: 10pt;">

<p style="text-align: left;">Risk is inherent in all investing. The value of your investment in Science &amp; Technology Opportunities, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time.&nbsp;<font class="_mt">You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments.</font> The following is a summary description of certain risks of investing in the Fund.</p>

<ul>

<li><b><i>Concentration Risk </i></b>&#8212; The Fund's strategy of concentrating in science and technology companies means that its performance will be closely tied to the performance of a particular market segment. The Fund's concentration in these companies may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. A downturn in these companies would have a larger impact on the Fund than on a mutual fund that does not concentrate in such companies. At times, the performance of these companies will lag the performance of other industries or the broader market as a whole. </li>

<li><b><i>Convertible Securities Risk </i></b>&#8212; The market value of a convertible security performs like that of a regular debt security; that is, if market interest rates rise, the value of a convertible security usually falls. In addition, convertible securities are subject to the risk that the issuer will not be able to pay interest or dividends when due, and their market value may change based on changes in the issuer's credit rating or the market's perception of the issuer's creditworthiness. Since it derives a portion of its value from the common stock into which it may be converted, a convertible security is also subject to the same types of market and issuer risk as apply to the underlying common stock. </li>

<li><b><i>Derivatives Risk </i></b>&#8212; The Fund's use of derivatives may reduce the Fund's returns and/or increase volatility. Volatility is defined as the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. A risk of the Fund's use of derivatives is that the fluctuations in their values may not correlate perfectly with the overall securities markets. </li>

<li><b><i>Emerging Markets Risk </i></b>&#8212; Emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets may be considered speculative.<br />Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging securities markets have far lower trading volumes and less liquidity than developed markets. </li>

<li><b><i>Equity Securities Risk </i></b>&#8212; Stock markets are volatile. The price of the equity securities fluctuates based on changes in a company's financial condition and overall market and economic conditions. </li>

<li><b><i>Foreign Securities Risk </i></b>&#8212; Foreign investments often involve special risks not present in U.S. investments that can increase the chances that the Fund will lose money. These risks include: </li></ul>

<ul>

<li><b><i>Geographic Concentration Risk </i></b>&#8212; From time to time the Fund may invest a substantial amount of its assets in issuers located in a single country or a limited number of countries. If the Fund concentrates its investments in this manner, it assumes the risk that economic, political and social conditions in those countries will have a significant impact on its investment performance. The Fund's investment performance may also be more volatile if it concentrates its investments in certain countries, especially emerging market countries. </li>

<li><b><i>Investment Style Risk </i></b>&#8212; Under certain market conditions, growth investments have performed better during the later stages of economic expansion. Therefore, this investment style may over time go in and out of favor. At times when the investment style used by the Fund is out of favor, the Fund may underperform other equity funds that use different investment styles. </li>

<li><b><i>Market Risk and Selection Risk </i></b>&#8212; Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Selection risk is the risk that the securities selected by Fund management will underperform the markets, the relevant indices or the securities selected by other funds with similar investment objectives and investment strategies. This means you may lose money. </li>

<li><b><i>Mid</i><i>Cap Securities Risk </i></b>&#8212; The securities of mid-cap companies generally trade in lower volumes and are generally subject to greater and less predictable price changes than the securities of larger capitalization companies. </li>

<li><b><i>"New Issues" Risk </i></b>&#8212; "New Issues" are initial public offerings of U.S. equity securities. Securities issued in IPOs have no trading history, and information about the companies may be available for very limited periods. In addition, the prices of securities sold in IPOs may be highly volatile or may decline shortly after the initial public offering. </li>

<li><b><i>Small Cap Securities Risk </i></b>&#8212; Small cap companies may have limited product lines or markets. They may be less financially secure than larger, more established companies. They may depend on a more limited management group than larger capitalized companies. </li>

<li><b><i>Technology Securities Risk </i></b>&#8212; Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. </li></ul></div></div> </div>falsefalsefalsefalsefalseOtherus-types:textBlockItemType<

All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement.

For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indicat

The Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets given in the Fund's most recent annual report which does not include the Acquired Fund Fees and Expenses. 2As described in the "Management of the Funds" section of the Fund's prospectus on pages 40-46, BlackRock Advisors, LLC ("BlackRock") has contractually agreed to waive or reimburse fees or expenses in order to limit Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursements (excluding Dividend Expense, Interest Expense, Acquired Fund Fees and Expenses and certain other Fund expenses) to 1.78% of average daily net assets until February 1, 2012. The Fund may have to repay some of these waivers and reimbursements to BlackRock in the following two years. The agreement may be terminated upon 90 days' notice by a majority of the non-interested trustees of the Trust or by a vote of a majority of the outstanding voting securities of 
the Fund. 17Annual Fund Operating Expenses (Science & Technology Opportunities Portfolio) (Service Shares)

<p style="text-align: left;"><font class="_mt">Under normal market conditions, Science &amp; Technology Opportunities invests at least 80% of its net assets in equity securities issued by U.S. and non-U.S. science and technology companies in all market capitalization ranges, selected for their rapid and sustainable growth potential from the development, advancement and use of science and/or use of technology. </font>The Fund may invest up to 25% of its net assets in emerging market countries.</p>

<p style="text-align: left;">Some of the industries likely to be represented in the Fund's portfolio holdings include: application software, IT consulting and services, internet software and services, networking equipment, telecom equipment, computer hardware, computer storage and peripherals, electronic equipment and instruments, semiconductors and equipment, aerospace and defense, electrical components and equipment, biotechnology, pharmaceuticals, healthcare equipment and supplies, healthcare distribution and services, healthcare facilities, industrial gases, specialty chemicals, advanced materials, integrated telecom services, alternative carriers and wireless telecommunication services.</p>

<p style="text-align: left;">The Fund primarily invests in common stock but may also invest in preferred stock and convertible securities. The Fund may also invest in Rule 144A securities, which are privately placed securities purchased by qualified institutional buyers. From time to time the Fund may invest in shares of companies through initial public offerings ("IPOs").</p>

<p style="text-align: left;">The Fund may, when consistent with the Fund's investment goal, buy or sell options or futures on a security or an index of securities and may buy options on a currency or a basket of currencies, or enter into foreign currency transactions, including swaps (collectively, commonly known as derivatives). The Fund typically uses derivatives as a substitute for taking a position in the underlying asset and/or as part of a strategy designed to reduce exposure to other risks, such as currency risk. The Fund may also use derivatives to enhance returns, in which case their use would involve leveraging risk. The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may also use forward foreign currency exchange contracts (obligations to buy or sell a currency at a set rate in the future). T

<p style="text-align: left;">Risk is inherent in all investing. The value of your investment in Science &amp; Technology Opportunities, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time.&nbsp;<font class="_mt">You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments.</font> The following is a summary description of certain risks of investing in the Fund.</p>

<ul>

<li><b><i>Concentration Risk </i></b>&#8212; The Fund's strategy of concentrating in science and technology companies means that its performance will be closely tied to the performance of a particular market segment. The Fund's concentration in these companies may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. A downturn in these companies would have a larger impact on the Fund than on a mutual fund that does not concentrate in such companies. At times, the performance of these companies will lag the performance of other industries or the broader market as a whole.</li>

<li><b><i>Convertible Securities Risk </i></b>&#8212; The market value of a convertible security performs like that of a regular debt security; that is, if market interest rates rise, the value of a convertible security usually falls. In addition, convertible securities are subject to the risk that the issuer will not be able to pay interest or dividends when due, and their market value may change based on changes in the issuer's credit rating or the market's perception of the issuer's creditworthiness. Since it derives a portion of its value from the common stock into which it may be converted, a convertible security is also subject to the same types of market and issuer risk as apply to the underlying common stock.</li>

<li><b><i>Derivatives Risk </i></b>&#8212; The Fund's use of derivatives may reduce the Fund's returns and/or increase volatility. Volatility is defined as the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. A risk of the Fund's use of derivatives is that the fluctuations in their values may not correlate perfectly with the overall securities markets.</li>

<li><b><i>Emerging Markets Risk </i></b>&#8212; Emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets may be considered speculative.<br />Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging securities markets have far lower trading volumes and less liquidity than developed markets.</li>

<li><b><i>Equity Securities Risk </i></b>&#8212; Stock markets are volatile. The price of the equity securities fluctuates based on changes in a company's financial condition and overall market and economic conditions.</li>

<li><b><i>Foreign Securities Risk </i></b>&#8212; Foreign investments often involve special risks not present in U.S. investments that can increase the chances that the Fund will lose money. These risks include: </li></ul>

<li><b><i>Geographic Concentration Risk </i></b>&#8212; From time to time the Fund may invest a substantial amount of its assets in issuers located in a single country or a limited number of countries. If the Fund concentrates its investments in this manner, it assumes the risk that economic, political and social conditions in those countries will have a significant impact on its investment performance. The Fund's investment performance may also be more volatile if it concentrates its investments in certain countries, especially emerging market countries. </li>

<li><b><i>Investment Style Risk </i></b>&#8212; Under certain market conditions, growth investments have performed better during the later stages of economic expansion. Therefore, this investment style may over time go in and out of favor. At times when the investment style used by the Fund is out of favor, the Fund may underperform other equity funds that use different investment styles.</li>

<li><b><i>Market Risk and Selection Risk </i></b>&#8212; Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Selection risk is the risk that the securities selected by Fund management will underperform the markets, the relevant indices or the securities selected by other funds with similar investment objectives and investment strategies. This means you may lose money.</li>

<li><b><i>Mid</i><i>Cap Securities Risk </i></b>&#8212; The securities of mid-cap companies generally trade in lower volumes and are generally subject to greater and less predictable price changes than the securities of larger capitalization companies. </li>

<li><b><i>"New Issues" Risk </i></b>&#8212; "New Issues" are initial public offerings of U.S. equity securities. Securities issued in IPOs have no trading history, and information about the companies may be available for very limited periods. In addition, the prices of securities sold in IPOs may be highly volatile or may decline shortly after the initial public offering. </li>

<li><b><i>Small Cap Securities Risk </i></b>&#8212; Small cap companies may have limited product lines or markets. They may be less financially secure than larger, more established companies. They may depend on a more limited management group than larger capitalized companies. </li>

<li><b><i>Technology Securities Risk </i></b>&#8212; Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. </li></ul></div> </div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.
