If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Additionally, the actions of a few large investors in the portfolio may have a significant adverse effect on other shareholders.</p><p>The Cash Management Portfolio is intended to have the least investment risk of the Fund&#8217;s portfolios because its principal investment strategy is to invest in short-term securities that are either government guaranteed or have very high credit ratings.

The portfolio may be affected by the following principal risks, among other non-principal risks:</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Interest Rate Risk:</b> Values of debt securities fluctuate as interest rates change. Debt securities with longer durations or fixed interest rates tend to be more sensitive to changes in interest rates, making them more volatile than debt securities with shorter durations or floating or adjustable interest rates.</p><p><b>&#8226; Credit Risk:</b> An issuer or guarantor of a debt instrument might be unable or unwilling to meet its financial obligations.</p><p><b>&#8226; U.S. Government Securities Risk:</b> Not all U.S. government securities are backed or guaranteed by the U.S. government. There is risk that the U.S. government will not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law.</p><p><b>&#8226; Mortgage-Related and Other Asset-Backed Securities Risk:</b> Mortgage-related and other asset-backed securities are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the market for the assets underlying such securities. As a result, during periods of declining asset value, difficult or frozen credit markets, swings in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to extension risk, where issuers may pay principal later than expected, and prepayment risk, where issuers may pay principal more quickly than expected, causing proceeds to be reinvested at lower prevailing interest rates.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

When selecting securities the manager employs a team-oriented investment process which considers sector allocation, issue selection, duration exposure, term structure weighting and country/currency allocations. Generally, the manager expects the portfolio&#8217;s average duration to be within a range of 2.5 to 7 years. Duration is often used to measure a bond&#8217;s sensitivity to interest rates. The longer a portfolio&#8217;s duration, the more sensitive it is to interest rate risk. The shorter a portfolio&#8217;s duration, the less sensitive it is to interest rate risk.</p><p>Principal investments include U.S. government and agency securities; corporate bonds and notes; convertible securities; and mortgage-backed securities. The portfolio may invest up to 25% of its assets in securities that are rated non-investment grade (high yield/high risk, sometimes called &#8220;junk bonds&#8221;) or if unrated, are of comparable quality as determined by the manager. The portfolio may also invest up to 25% of its assets in foreign securities (equity and debt). However, the portfolio will not invest more than 20% of its assets in non-U.S. dollar denominated securities, including emerging markets.</p><p>The manager uses futures, forwards, swaps and option contracts (derivatives). Futures are purchased and sold to adjust interest rate exposure (duration) and/or as a substitute for the physical security. Foreign currency futures, forwards or options are purchased or sold to gain or increase exposure to various currency markets and/or to hedge against foreign currency fluctuations. Interest rate swaps are used to adjust interest rate exposures and/or as a substitute for the physical security. Credit default swaps are used to manage default risk of an issuer and/or to gain exposure to a portion of the fixed income market or an individual issuer. Options are primarily purchased to manage interest rate and volatility exposures or are sold to generate income.</p><p>The manager may invest in forward commitments (i.e., securities that are purchased or sold with payment and delivery taking place in the future), such as mortgage TBA (&#8220;to be announced&#8221;) transactions that are purchased to gain exposure to the mortgage market.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non-principal risks:</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Interest Rate Risk:</b> Values of debt securities fluctuate as interest rates change. Debt securities with longer durations or fixed interest rates tend to be more sensitive to changes in interest rates, making them more volatile than debt securities with shorter durations or floating or adjustable interest rates.</p><p><b>&#8226; Credit Risk:</b> An issuer or guarantor of a debt instrument might be unable or unwilling to meet its financial obligations.</p><p><b>&#8226; U.S. Government Securities Risk:</b> Not all U.S. government securities are backed or guaranteed by the U.S. government. There is risk that the U.S. government will not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law.</p><p><b>&#8226; High-Yield or &#8220;Junk&#8221; Securities Risk:</b> High yield securities are typically issued by companies that are highly leveraged, less creditworthy or financially distressed and are considered to be mostly speculative in nature (high risk), are potentially less liquid, and have a greater risk of loss, that is they are more likely to default than higher rated securities.</p><p><b>&#8226; Mortgage-Related and Other Asset-Backed Securities Risk:</b> Mortgage-related and other asset-backed securities are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the market for the assets underlying such securities. As a result, during periods of declining asset value, difficult or frozen credit markets, swings in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to extension risk, where issuers may pay principal later than expected, and prepayment risk, where issuers may pay principal more quickly than expected, causing proceeds to be reinvested at lower prevailing interest rates.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer. The volatility of non-investment grade debt securities (including loans) may be greater than for investment grade securities.</p><p><b>&#8226; Convertible Securities Risk:</b> Convertible securities have <i>credit risk</i> and <i>interest rate risk</i> and may present less risk than investments in a company&#8217;s common stock but more risk than investments in the company&#8217;s senior debt securities.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition,foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Emerging Markets Risk:</b> Investments in or exposure to investments in emerging markets, such as those in Latin America, Asia, the Middle East, Eastern Europe and Africa, may be riskier than developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, political and economic instability, less governmental regulation of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations. Investments in non-investment grade debt securities (sometimes called &#8220;junk bonds&#8221;) have a greater risk of being or becoming less liquid than investments in other, higher-rated debt securities.</p><p><b>&#8226; Derivatives Risk:</b> Derivatives can be complex instruments, which may experience sudden and unpredictable changes in price or liquidity and may be difficult to value, sell or unwind. The value of derivatives is based on the value of other securities or indexes. They can also create investment exposure that is greater than their cost may suggest (known as <i>leverage risk</i>). Derivative transactions may also involve a counterparty. Such transactions are subject to the credit risk and/or the ability of the counterparty to perform in accordance with the terms of the transaction.</p><p><b>&#8226; Leverage Risk:</b> Leverage is investment exposure which exceeds the initial amount invested. Leverage can cause the portfolio to lose more than the principal amount invested. Leverage can magnify the portfolio&#8217;s gains and losses and therefore increase its volatility.</p><p><b>&#8226; Forward Commitments Risk:</b> Fixed income securities may be purchased on a &#8220;forward commitment&#8221; or &#8220;when-issued&#8221; basis (meaning securities are purchased or sold with payment and delivery taking place in the future). In forward commitment or when-issued transactions, if the seller or buyer, as the case may be, fails to consummate the transaction, the counterparty may miss the opportunity of obtaining a price or yield considered to be advantageous.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Floating rate loans are those with interest rates which float, adjust or vary periodically based upon a benchmark indicator, a specified adjustment schedule or prevailing interest rates. Borrowers may include corporations, partnerships and other entities that operate in a variety of industries and geographic regions. Floating rate loans in which the portfolio invests include senior loans of domestic and foreign borrowers. Senior loans are debt instruments that may have a right to payment that is senior to most other debts of the borrowers. The portfolio may invest in participations in senior loans, may purchase assignments of portions of senior loans from third parties and may act as one of the group of lenders originating a senior loan. Generally, senior floating rate loans are secured by specific assets of the borrower. However, the portfolio may invest up to 20% of its assets in senior loans that are not secured by any collateral.</p><p>The portfolio may invest all or substantially all of its assets in senior loans and other debt instruments that are rated non- investment grade (high yield/high risk, sometimes called &#8220;junk bonds&#8221;) or if unrated, are of comparable quality as determined by the manager.</p><p>The manager seeks to invest in a portfolio of loans that it believes will be less volatile over time than the general loan market.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non- principal risks:</p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Credit Risk:</b> An issuer or guarantor of a debt instrument might be unable or unwilling to meet its financial obligations.</p><p><b>&#8226; High-Yield or &#8220;Junk&#8221; Securities Risk:</b> High yield securities are typically issued by companies that are highly leveraged, less creditworthy or financially distressed and are considered to be mostly speculative in nature (high risk), are potentially less liquid, and have a greater risk of loss, that is they are more likely to default than higher rated securities.</p><p><b>&#8226; Floating Rate Loan Risk:</b> Floating rate loans (or bank loans) are usually rated below investment grade. The market for floating rate loans may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. Investments in floating rate loans are typically in the form of an assignment or participation. Investors in a loan participation assume the credit risk associated with the borrower and may assume the credit risk associated with an interposed financial intermediary. Accordingly, if a lead lender becomes insolvent or a loan is foreclosed, the portfolio could experience delays in receiving payments or suffer a loss. In an assignment, the portfolio effectively becomes a lender under the loan agreement with the same rights and obligations as the assigning bank or other financial intermediary. Accordingly, if the loan is foreclosed, the portfolio could become part owner of any collateral, and would bear the costs and liabilities associated with owning and disposing of the collateral.</p><p><b>&#8226; Interest Rate Risk:</b> Values of debt securities fluctuate as interest rates change. Debt securities with longer durations or fixed interest rates tend to be more sensitive to changes in interest rates, making them more volatile than debt securities with shorter durations or floating or adjustable interest rates.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer. The volatility of non-investment grade debt securities (including loans) may be greater than for investment grade securities.</p><p><b>&#8226; Non-Diversification Risk:</b> The portfolio is classified as non- diversified and may invest a greater percentage of its assets in a single issuer or a fewer number of issuers than a diversified portfolio. This increases potential price volatility and the risk that its value could go down because of the poor performance of a single investment or a small number of investments. Being classified as non-diversified does not prevent the manager from managing as though it were a diversified portfolio.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non- principal risks:</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer. The volatility of non-investment grade debt securities (including loans) may be greater than for investment grade securities.</p><p><b>&#8226; Interest Rate Risk:</b> Values of debt securities fluctuate as interest rates change. Debt securities with longer durations or fixed interest rates tend to be more sensitive to changes in interest rates, making them more volatile than debt securities with shorter durations or floating or adjustable interest rates.</p><p><b>&#8226; Credit Risk:</b> An issuer or guarantor of a debt instrument might be unable or unwilling to meet its financial obligations.</p><p><b>&#8226; High-Yield or &#8220;Junk&#8221; Securities Risk:</b> High yield securities are typically issued by companies that are highly leveraged, less creditworthy or financially distressed and are considered to be mostly speculative in nature (high risk), are potentially less liquid, and have a greater risk of loss, that is they are more likely to default than higher rated securities.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations. Investments in non-investment grade debt securities (sometimes called junk bonds) and asset-backed securities have a greater risk of being or becoming less liquid than investments in other, higher-rated debt securities.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Normally, the portfolio focuses on investment in or exposure to inflation-indexed bonds. It is expected that the amount invested in or exposed to inflation-indexed bonds (either through cash market purchases, forward commitments or derivative instruments) normally will be equivalent to at least 80% of the portfolio&#8217;s net assets. Inflation-indexed bonds are fixed income securities whose principal value or coupon payments are periodically adjusted according to an inflation index. If the index measuring inflation falls, the principal value of inflation- indexed bonds and/or interest payable on such bonds tends to fall. Duration management is a fundamental part of the investment strategy for this portfolio. Duration is often used to measure a bond&#8217;s sensitivity to interest rates. The longer a portfolio&#8217;s duration, the more sensitive it is to interest rate risk. The shorter a portfolio&#8217;s duration, the less sensitive it is to interest rate risk.</p><p>The portfolio may also invest in fixed income securities of U.S. and foreign issuers (including emerging markets), including mortgage-related securities; corporate bonds and notes; and derivative instruments and forward commitments relating to the previously mentioned securities.</p><p>When selecting securities, the manager:</p><p>&#8226; Decides what duration to maintain. The portfolio&#8217;s average duration is generally expected to be within approximately 3 years of the portfolio&#8217;s benchmark index duration.</p><p>&#8226; Decides how to allocate among short, intermediate and long duration issues and how much should be invested in various types of investments.</p><p>&#8226; Chooses companies to invest in by carrying out credit analysis of potential investments.</p><p>The manager frequently uses futures, forwards, swaps and option contracts (derivatives). Futures are purchased and sold to adjust interest rate exposure (duration) and/or as a substitute for the physical security. Foreign currency futures, forwards or options are purchased or sold to gain or increase exposure to various currency markets and/or to hedge against foreign currency fluctuations. Interest rate swaps are used to adjust interest rate exposures and/or as a substitute for the physical security. Credit default swaps are used to manage default risk of an issuer and/or to gain exposure to a portion of the fixed income market or an individual issuer. Options are primarily purchased to manage interest rate and volatility exposures or are sold to generate income.</p><p>A substantial portion of the portfolio is expected to be invested in forward commitments (i.e., securities that are purchased or sold with payment and delivery taking place in the future) on inflation-indexed bonds to gain exposure to the inflation linked market.</p><p>In addition to the strategies described above, the portfolio typically uses derivatives and/or forward commitments as part of a strategy designed to reduce exposure to other risks, and to satisfy issuer diversification requirements.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non- principal risks:</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Interest Rate Risk:</b> Values of debt securities fluctuate as interest rates change. Debt securities with longer durations or fixed interest rates tend to be more sensitive to changes in interest rates, making them more volatile than debt securities with shorter durations or floating or adjustable interest rates.</p><p><b>&#8226; Inflation-Indexed Debt Securities Risk:</b> The principal values of inflation-indexed debt securities tend to increase when inflation rises and decrease when inflation falls.</p><p><b>&#8226; Credit Risk:</b> An issuer or guarantor of a debt instrument might be unable or unwilling to meet its financial obligations.</p><p><b>&#8226; U.S. Government Securities Risk:</b> Not all U.S. government securities are backed or guaranteed by the U.S. government. There is risk that the U.S. government will not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Emerging Markets Risk:</b> Investments in or exposure to investments in emerging markets, such as those in Latin America, Asia, the Middle East, Eastern Europe and Africa, may be riskier than developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, political and economic instability, less governmental regulation of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.</p><p><b>&#8226; Mortgage-Related and Other Asset-Backed Securities Risk:</b> Mortgage-related and other asset-backed securities are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the market for the assets underlying such securities. As a result, during periods of declining asset value, difficult or frozen credit markets, swings in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to extension risk, where issuers may pay principal later than expected, and prepayment risk, where issuers may pay principal more quickly than expected, causing proceeds to be reinvested at lower prevailing interest rates.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations.</p><p><b>&#8226; Leverage Risk:</b> Leverage is investment exposure which exceeds the initial amount invested. Leverage can cause the portfolio to lose more than the principal amount invested. Leverage can magnify the portfolio&#8217;s gains and losses and therefore increase its volatility.</p><p><b>&#8226; Derivatives Risk:</b> Derivatives can be complex instruments, which may experience sudden and unpredictable changes in price or liquidity and may be difficult to value, sell or unwind. The value of derivatives is based on the value of other securities or indexes. They can also create investment exposure that is greater than their cost may suggest (known as <i>leverage risk</i>). Derivative transactions may also involve a counterparty. Such transactions are subject to the credit risk and/or the ability of the counterparty to perform in accordance with the terms of the transaction.</p><p><b>&#8226; Forward Commitments Risk:</b> Fixed income securities may be purchased on a &#8220;forward commitment&#8221; or &#8220;when-issued&#8221; basis (meaning securities are purchased or sold with payment and delivery taking place in the future). In forward commitment or when-issued transactions, if the seller or buyer, as the case may be, fails to consummate the transaction, the counterparty may miss the opportunity of obtaining a price or yield considered to be advantageous.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Normally, the portfolio focuses on investment in or exposure to inflation-indexed bonds. It is expected that the amount invested in or exposed to inflation-indexed bonds (either through cash market purchases, forward commitments or derivative instruments) normally will be equivalent to at least 80% of the portfolio&#8217;s net assets. Inflation-indexed bonds are fixed income securities whose principal value or coupon payments are periodically adjusted according to an inflation index. If the index measuring inflation falls, the principal value of inflation- indexed bonds and/or interest payable on such bonds tends to fall. Duration management is a fundamental part of the investment strategy for this portfolio. Duration is often used to measure a bond&#8217;s sensitivity to interest rates. The longer a portfolio&#8217;s duration, the more sensitive it is to interest rate risk. The shorter a portfolio&#8217;s duration, the less sensitive it is to interest rate risk.</p><p>The portfolio may also invest in fixed income securities of U.S. and foreign issuers. Under normal market conditions, the portfolio may invest up to 40% of the portfolio&#8217;s assets in non-U.S. dollar denominated securities, 20% of which may be unhedged.</p><p>When selecting investments, the manager:</p><p>&#8226; Uses fundamental investment techniques to select investments.</p><p>&#8226; Decides what duration to maintain. The portfolio&#8217;s average duration is generally expected to be within approximately 20% (plus or minus) of the portfolio&#8217;s benchmark index duration.</p><p>&#8226; Decides how to allocate among short, intermediate and long duration issues and how much should be invested in various types of investments.</p><p>The manager frequently uses futures, forwards, swaps and options contracts (derivatives). Foreign currency futures, forwards or options are purchased or sold to gain or increase exposure to various currency markets and/or to hedge against currency fluctuations. Total return swaps are used to receive the return of a reference asset, such as an index.</p><p>A portion of the portfolio is also expected to be invested in forward commitments (i.e., securities that are purchased or sold with payment and delivery taking place in the future) on inflation-indexed bonds to gain exposure to the inflation linked market.</p><p>In addition to the strategies described above, the portfolio typically uses derivatives and/or forward commitments as part of a strategy designed to reduce exposure to other risks, and to satisfy issuer diversification requirements.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non- principal risks:</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Interest Rate Risk:</b> Values of debt securities fluctuate as interest rates change. Debt securities with longer durations or fixed interest rates tend to be more sensitive to changes in interest rates, making them more volatile than debt securities with shorter durations or floating or adjustable interest rates.</p><p><b>&#8226; Inflation-Indexed Debt Securities Risk:</b> The principal values of inflation-indexed debt securities tend to increase when inflation rises and decrease when inflation falls.</p><p><b>&#8226; Credit Risk:</b> An issuer or guarantor of a debt instrument might be unable or unwilling to meet its financial obligations.</p><p><b>&#8226; U.S. Government Securities Risk:</b> Not all U.S. government securities are backed or guaranteed by the U.S. government. There is risk that the U.S. government will not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market or the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations.</p><p><b>&#8226; Leverage Risk:</b> Leverage is investment exposure which exceeds the initial amount invested. Leverage can cause the portfolio to lose more than the principal amount invested. Leverage can magnify the portfolio&#8217;s gains and losses and therefore increase its volatility.</p><p><b>&#8226; Derivatives Risk:</b> Derivatives can be complex instruments, which may experience sudden and unpredictable changes in price or liquidity and may be difficult to value, sell or unwind. The value of derivatives is based on the value of other securities or indexes. They can also create investment exposure that is greater than their cost may suggest (known as <i>leverage risk</i>). Derivative transactions may also involve a counterparty. Such transactions are subject to the credit risk and/or the ability of the counterparty to perform in accordance with the terms of the transaction.</p><p><b>&#8226; Forward Commitments Risk:</b> Fixed income securities may be purchased on a &#8220;forward commitment&#8221; or &#8220;when-issued&#8221; basis (meaning securities are purchased or sold with payment and delivery taking place in the future). In forward commitment or when-issued transactions, if the seller or buyer, as the case may be, fails to consummate the transaction, the counterparty may miss the opportunity of obtaining a price or yield considered to be advantageous.</p><p><b>&#8226; Non-Diversification Risk:</b> The portfolio is classified as non- diversified and may invest a greater percentage of its assets in a single issuer or a fewer number of issuers than a diversified portfolio. This increases potential price volatility and the risk that its value could go down because of the poor performance of a single investment or a small number of investments.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The securities will principally include medium to high quality, investment grade securities with varying terms to maturity. The portfolio may invest in U.S. and foreign issuers (including emerging markets), including government and agency issued securities; mortgage- related securities; corporate bonds and notes; and commercial paper and other money market instruments. Duration management is a fundamental part of the investment strategy for this portfolio. Duration is often used to measure a bond&#8217;s sensitivity to interest rates. The longer a portfolio&#8217;s duration, the more sensitive it is to interest rate risk. The shorter a portfolio&#8217;s duration, the less sensitive it is to interest rate risk.</p><p>When selecting securities, the manager:</p><p>&#8226; Decides what duration to maintain. The portfolio&#8217;s average duration is generally expected to be within approximately 2 years of the portfolio&#8217;s benchmark index.</p><p>&#8226; Decides how to allocate among short, intermediate and long duration issues and how much should be invested in various types of instruments.</p><p>&#8226; Chooses companies to invest in by carrying out a credit analysis of potential investments.</p><p>The manager frequently uses futures, forwards, swaps and option contracts (derivatives). Futures are purchased and sold to adjust interest rate exposure (duration) and/or as a substitute for the physical security. Foreign currency futures, forwards or options are purchased or sold to gain or increase exposure to various currency markets and/or to hedge against foreign currency fluctuations. Interest rate swaps are used to adjust interest rate exposures and/or as a substitute for the physical security. Credit default swaps are used to manage default risk of an issuer and/or to gain exposure to a portion of the fixed income market or an individual issuer. Options are primarily purchased to manage interest rate and volatility exposures or are sold to generate income.</p><p>The manager may invest in forward commitments (i.e., securities that are purchased or sold with payment and delivery taking place in the future), such as mortgage TBA (&#8220;to be announced&#8221;) transactions that are purchased to gain exposure to the mortgage market.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non- principal risks:</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Interest Rate Risk:</b> Values of debt securities fluctuate as interest rates change. Debt securities with longer durations or fixed interest rates tend to be more sensitive to changes in interest rates, making them more volatile than debt securities with shorter durations or floating or adjustable interest rates.</p><p><b>&#8226; Credit Risk:</b> An issuer or guarantor of a debt instrument might be unable or unwilling to meet its financial obligations.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b>&#8226; Mortgage-Related and Other Asset-Backed Securities Risk:</b> Mortgage-related and other asset-backed securities are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the market for the assets underlying such securities. As a result, during periods of declining asset value, difficult or frozen credit markets, swings in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to extension risk, where issuers may pay principal later than expected, and prepayment risk, where issuers may pay principal more quickly than expected, causing proceeds to be reinvested at lower prevailing interest rates.</p><p><b>&#8226; U.S. Government Securities Risk:</b> Not all U.S. government securities are backed or guaranteed by the U.S. government. There is risk that the U.S. government will not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Emerging Markets Risk:</b> Investments in or exposure to investments in emerging markets, such as those in Latin America, Asia, the Middle East, Eastern Europe and Africa, may be riskier than developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, political and economic instability, less governmental regulation of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations.</p><p><b>&#8226; Leverage Risk:</b> Leverage is investment exposure which exceeds the initial amount invested. Leverage can cause the portfolio to lose more than the principal amount invested. Leverage can magnify the portfolio&#8217;s gains and losses and therefore increase its volatility.</p><p><b>&#8226; Derivatives Risk:</b> Derivatives can be complex instruments, which may experience sudden and unpredictable changes in price or liquidity and may be difficult to value, sell or unwind. The value of derivatives is based on the value of other securities or indexes. They can also create investment exposure that is greater than their cost may suggest (known as <i>leverage risk</i>). Derivative transactions may also involve a counterparty. Such transactions are subject to the credit risk and/or the ability of the counterparty to perform in accordance with the terms of the transaction.</p><p><b>&#8226; Forward Commitments Risk:</b> Fixed income securities may be purchased on a &#8220;forward commitment&#8221; or &#8220;when-issued&#8221; basis (meaning securities are purchased or sold with payment and delivery taking place in the future). In forward commitment or when-issued transactions, if the seller or buyer, as the case may be, fails to consummate the transaction, the counterparty may miss the opportunity of obtaining a price or yield considered to be advantageous.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Normally the portfolio will focus on high quality, investment grade securities. Generally, the manager expects to track duration of the Barclays Capital 1-3 Year Government/Credit Bond Index (plus or minus a half-year) although the securities held may have short, intermediate, and long terms to maturity. In addition to making active sector allocations and security selection decisions, the manager also monitors portfolio duration as part of the management for this portfolio. The portfolio&#8217;s average duration will not likely exceed 3 years. Duration is often used to measure a bond&#8217;s sensitivity to interest rates. The longer a portfolio&#8217;s duration, the more sensitive it is to interest rate risk. The shorter a portfolio&#8217;s duration, the less sensitive it is to interest rate risk.</p><p>The manager intends to invest principally in U.S. government and agency securities, mortgage-related securities, asset-backed securities, corporate debt securities and derivatives thereof, repurchase agreements collateralized by U.S. government securities, and money market instruments. The portfolio may invest up to 55% of its assets in investment grade corporate debt securities, including derivatives thereof. The portfolio may invest up to 15% of its assets in foreign debt denominated in U.S. dollars.</p><p>Within this broad structure, investment decisions reflect the manager&#8217;s outlook for interest rates and the economy as well as the prices and yields of the various securities.</p><p>The portfolio may sell holdings for a variety of reasons, such as to adjust the portfolio&#8217;s average maturity, duration, or credit quality or to shift assets into and out of higher yielding or lower yielding securities or different sectors.</p><p> The manager uses futures, forwards and swaps (derivatives). Futures are purchased and sold to adjust interest rate exposure (duration) and/or as a substitute for the physical security. Foreign currency futures, forwards or options are sold to hedge against foreign currency fluctuations. Interest rate swaps are used to adjust interest rate exposures and/or as a substitute for the physical security.</p><p> The manager may invest in forward commitments (i.e., securities that are purchased or sold with payment and delivery taking place in the future), such as mortgage TBA (&#8220;to be announced&#8221;) transactions that are purchased to gain exposure to the mortgage market.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non-principal risks:</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b>&#8226; Interest Rate Risk:</b> Values of debt securities fluctuate as interest rates change. Debt securities with longer durations or fixed interest rates tend to be more sensitive to changes in interest rates, making them more volatile than debt securities with shorter durations or floating or adjustable interest rates.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Credit Risk:</b> An issuer or guarantor of a debt instrument might be unable or unwilling to meet its financial obligations.</p><p><b> &#8226; Mortgage-Related and Other Asset-Backed Securities Risk:</b> Mortgage-related and other asset-backed securities are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the market for the assets underlying such securities. As a result, during periods of declining asset value, difficult or frozen credit markets, swings in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to extension risk, where issuers may pay principal later than expected, and prepayment risk, where issuers may pay principal more quickly than expected, causing proceeds to be reinvested at lower prevailing interest rates.</p><p><b> &#8226; U.S. Government Securities Risk:</b> Not all U.S. government securities are backed or guaranteed by the U.S. government. There is risk that the U.S. government will not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations.</p><p><b>&#8226; Derivatives Risk:</b> Derivatives can be complex instruments, which may experience sudden and unpredictable changes in price or liquidity and may be difficult to value, sell or unwind. The value of derivatives is based on the value of other securities or indexes. They can also create investment exposure that is greater than their cost may suggest (known as <i>leverage risk</i>). Derivative transactions may also involve a counterparty. Such transactions are subject to the credit risk and/or the ability of the counterparty to perform in accordance with the terms of the transaction.</p><p><b> &#8226; Leverage Risk:</b> Leverage is investment exposure which exceeds the initial amount invested. Leverage can cause the portfolio to lose more than the principal amount invested. Leverage can magnify the portfolio&#8217;s gains and losses and therefore increase its volatility.</p><p><b>&#8226; Forward Commitments Risk:</b> Fixed income securities may be purchased on a &#8220;forward commitment&#8221; or &#8220;when-issued&#8221; basis (meaning securities are purchased or sold with payment and delivery taking place in the future). In forward commitment or when-issued transactions, if the seller or buyer, as the case may be, fails to consummate the transaction, the counterparty may miss the opportunity of obtaining a price or yield considered to be advantageous.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other nonprincipal risks:</p> <p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p> <p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p> <p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p> <p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p> <p><b>&#8226; Growth Companies Risk:</b> Growth companies have the potential for above average or rapid growth but may give the portfolio a higher risk of price volatility than investments in &#8220;undervalued&#8221; companies.</p> <p><b> &#8226; Master/Feeder Mutual Fund Structure:</b> The portfolio bears the fees and expenses of the Master Fund in addition to its own fees and expenses, which could result in a higher overall expense ratio.</p> <p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p> <p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

If the Fund provides this disclosure, also disclose the period for which the expense reimbursement or fee waiver arrangement is expected to continue, and briefly describe who can terminate the arrangement and under what circumstances.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Paragraph 1 -Subparagraph 11 -Subsection table falsefalseLess fee waiver0rr_FeeWaiverOrReimbursementOverAssetstruefalsefalsefalsefalsefalsefalsefalsefalsefalsefalse[2]1falsefalsefalse00falsefalsefalsefalsefalse2truetruetrue-0.0034-0.0034falsefalsefalsetruefalse3truetruetrue-0.0034-0.0034falsefalsefalsetruefalseOthernanafalsefalseLess fee waiver7falseRowprimaryElement*10false0rr_NetExpensesOverAssetsrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseverboselabel1falsetruetrue00falsefalsefalsetruefalse2truetruetrue0.00910.0091falsefalsefalsetruefalse3truetruetrue0.00710.0071falsefalsefalsetruefalseOtherrr:NonNegativePure4TypepureTotal Annual Fund Operating Expenses.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Paragraph 1 -Subparagraph 11 -Subsection table falsefalseTotal annual operating expenses after fee waiver0rr_NetExpensesOverAssetstruefalsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsefalsefalse2truetruetrue0.00910.0091falsefalsefalsetruefalse3truetruetrue0.00710.0071falsefalsefalsetruefalseOthernanafalsefalseTotal annual operating expenses after fee waiver1The table and Examples reflect the expenses of both the portfolio and the Master Growth-Income Fund.2The investment adviser of this portfolio has contractually agreed to waive a portion of its advisory fee so that its advisory fee does not exceed an annual rate of 0.41%, through April 30, 2012.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non principal risks:</p> <p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p> <p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p> <p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p> <p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events. </p> <p><b>&#8226; Mid-Capitalization Companies Risk:</b> Mid-capitalization companies may be riskier and more susceptible to price swings than larger companies. Mid-capitalization companies may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger, more established companies. </p> <p><b> &#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p> <p><b>&#8226; Growth Companies Risk:</b> Growth companies have the potential for above average or rapid growth but may give the portfolio a higher risk of price volatility than investments in &#8220;undervalued&#8221; companies. </p> <p><b>&#8226; Dividend-Oriented Companies Risk:</b> Companies that have historically paid regular dividends to shareholders may decrease or eliminate dividend payments in the future. A decrease in dividend payments by an issuer may result in a decrease in the value of the issuer&#8217;s stock and less available capital for the portfolio.</p> <p><b> &#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p> <p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p> <p><b>&#8226; Master/Feeder Mutual Fund Structure:</b> The portfolio bears the fees and expenses of the Master Fund in addition to its own fees and expenses, which could result in a higher overall expense ratio.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

If the Fund provides this disclosure, also disclose the period for which the expense reimbursement or fee waiver arrangement is expected to continue, and briefly describe who can terminate the arrangement and under what circumstances.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Paragraph 1 -Subparagraph 11 -Subsection table falsefalseLess fee waiver0rr_FeeWaiverOrReimbursementOverAssetstruefalsefalsefalsefalsefalsefalsefalsefalsefalsefalse[1]1falsefalsefalse00falsefalsefalsefalsefalse2truetruetrue-0.0002-0.0002falsefalsefalsetruefalse3truetruetrue-0.0002-0.0002falsefalsefalsetruefalseOthernanafalsefalseLess fee waiver7falseRowprimaryElement*10false0rr_NetExpensesOverAssetsrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseverboselabel1falsetruetrue00falsefalsefalsetruefalse2truetruetrue0.00910.0091falsefalsefalsetruefalse3truetruetrue0.00710.0071falsefalsefalsetruefalseOtherrr:NonNegativePure4TypepureTotal Annual Fund Operating Expenses.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Paragraph 1 -Subparagraph 11 -Subsection table falsefalseTotal annual operating expenses after fee waiver0rr_NetExpensesOverAssetstruefalsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsefalsefalse2truetruetrue0.00910.0091falsefalsefalsetruefalse3truetruetrue0.00710.0071falsefalsefalsetruefalseOthernanafalsefalseTotal annual operating expenses after fee waiver1The investment adviser has contractually agreed to waive 0.015% (rounded in fee table) of its management fee through April 30, 2012.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non-principal risks:</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b> &#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b> &#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events. </p><p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p><p><b>&#8226; Mid-Capitalization Companies Risk:</b> Mid-capitalization companies may be riskier and more susceptible to price swings than larger companies. Mid-capitalization companies may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger, more established companies.</p><p><b>&#8226; Value Companies Risk:</b> Value companies are those that are thought to be undervalued and that a company&#8217;s stock is trading for less than its intrinsic value. There is a risk that the determination that a stock is undervalued is not correct or is not recognized in the market.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Base the percentages of "Annual Fund Operating Expenses" on amounts incurred during the Fund's most recent fiscal year, but include in expenses amounts that would have been incurred absent expense reimbursement or fee waiver arrangements. If the Fund has changed its fiscal year and, as a result, the most recent fiscal year is less than three months, use the fiscal year prior to the most recent fiscal year as the basis for determining "Annual Fund Operating Expenses."Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Paragraph 3 -Subparagraph d -Subsection instructions falsefalseTotal annual operating expenses0rr_ExpensesOverAssetstruefalsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsefalsefalse2truetruetrue0.00900.0090falsefalsefalsetruefalse3truetruetrue0.00700.0070falsefalsefalsetruefalseOthernanafalsefalseTotal annual operating expenses35Annual Fund Operating Expenses - Dividend Growth Portfolio UnKnownUnKnownUnKnownUnKnownfalsetrueColumnperiodPeriod*Columndei_DocumentInformationDocumentAxisAxis*Columnrr_ProspectusShareClassAxisAxis*ColumnunitUnit*RowprimaryElement*falsefalsefalseOtherus-types:textBlockItemTypestringContains a command for the SEC Viewer for the role corresponding to OperatingExpensesData.No authoritative reference available.falsefalseAnnual Fund Operating Expenses [Table]279false0rr_ExpenseExampleHeadingrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00ExamplesfalsefalsefalsefalsefalseOtherxbrli:stringItemTypestringHeading for Expense Example.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Paragraph 4 -Subsection instructions falsefalseExpense Example [Heading]280false0rr_ExpenseExampleNarrativeTextBlockrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00<p>The examples below are intended to help you compare the cost of investing in the portfolio with the cost of investing in other portfolios of the Fund or other mutual funds.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non principal risks:</p> <p><b> &#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p> <p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p> <p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p> <p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p> <p><b>&#8226; Dividend-Oriented Companies Risk:</b> Companies that have historically paid regular dividends to shareholders may decrease or eliminate dividend payments in the future. A decrease in dividend payments by an issuer may result in a decrease in the value of the issuer&#8217;s stock and less available capital for the portfolio.</p> <p><b> &#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p> <p><b>&#8226; Mid-Capitalization Companies Risk:</b> Mid-capitalization companies may be riskier and more susceptible to price swings than larger companies. Mid-capitalization companies may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger, more established companies.</p> <p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition,foreign markets can react differently to these conditions than the U.S. market.</p> <p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Base the percentages of "Annual Fund Operating Expenses" on amounts incurred during the Fund's most recent fiscal year, but include in expenses amounts that would have been incurred absent expense reimbursement or fee waiver arrangements. If the Fund has changed its fiscal year and, as a result, the most recent fiscal year is less than three months, use the fiscal year prior to the most recent fiscal year as the basis for determining "Annual Fund Operating Expenses."Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Paragraph 3 -Subparagraph d -Subsection instructions falsefalseTotal annual operating expenses0rr_ExpensesOverAssetstruefalsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsefalsefalse2truetruetrue0.00280.0028falsefalsefalsetruefalse3truetruetrue0.00080.0008falsefalsefalsetruefalseOthernanafalsefalseTotal annual operating expenses35Annual Fund Operating Expenses - Equity Index Portfolio UnKnownUnKnownUnKnownUnKnownfalsetrueColumnperiodPeriod*Columndei_DocumentInformationDocumentAxisAxis*Columnrr_ProspectusShareClassAxisAxis*ColumnunitUnit*RowprimaryElement*falsefalsefalseOtherus-types:textBlockItemTypestringContains a command for the SEC Viewer for the role corresponding to OperatingExpensesData.No authoritative reference available.falsefalseAnnual Fund Operating Expenses [Table]304false0rr_ExpenseExampleHeadingrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00ExamplesfalsefalsefalsefalsefalseOtherxbrli:stringItemTypestringHeading for Expense Example.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Paragraph 4 -Subsection instructions falsefalseExpense Example [Heading]305false0rr_ExpenseExampleNarrativeTextBlockrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00<p>The examples below are intended to help you compare the cost of investing in the portfolio with the cost of investing in other portfolios of the Fund or other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non principal risks:</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b> &#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b> &#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p><p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p><p><b>&#8226; Mid-Capitalization Companies Risk:</b> Mid-capitalization companies may be riskier and more susceptible to price swings than larger companies. Mid-capitalization companies may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger, more established companies.</p><p><b>&#8226; Small-Capitalization Companies Risk:</b> Small-capitalization companies may be riskier and more susceptible to price swings than larger companies. Small-capitalization companies, particularly those in their developmental stages, may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger more established companies.</p><p><b>&#8226; Non-Diversification Risk:</b> The portfolio is classified as non- diversified and may invest a greater percentage of its assets in a single issuer or a fewer number of issuers than a diversified portfolio. This increases potential price volatility and the risk that its value could go down because of the poor performance of a single investment or a small number of investments.</p><p><b>&#8226; Small Number of Holdings Risk:</b> A portfolio with a small number of holdings may have greater exposure to those holdings which could increase potential price volatility compared to portfolios with a greater number of holdings.</p><p><b>&#8226; Growth Companies Risk:</b> Growth companies have the potential for above average or rapid growth but may give the portfolio a higher risk of price volatility than investments in &#8220;undervalued&#8221; companies.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Emerging Markets Risk:</b> Investments in or exposure to investments in emerging markets, such as those in Latin America, Asia, the Middle East, Eastern Europe and Africa, may be riskier than developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, political and economic instability, less governmental regulation of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Geographic Concentration Risk:</b> Concentrating investments in a single country, a limited number of countries, or a particular geographic region makes the portfolio more susceptible to adverse economic, political, social, regulatory and other developments in that country, countries or region.</p><p><b> &#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other nonprincipal risks:</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b> &#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events. </p><p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p><p><b>&#8226; Mid-Capitalization Companies Risk:</b> Mid-capitalization companies may be riskier and more susceptible to price swings than larger companies. Mid-capitalization companies may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger, more established companies.</p><p><b>&#8226; Small-Capitalization Companies Risk:</b> Small-capitalization companies may be riskier and more susceptible to price swings than larger companies. Small-capitalization companies, particularly those in their developmental stages, may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger more established companies.</p><p><b> &#8226; Growth Companies Risk:</b> Growth companies have the potential for above average or rapid growth but may give the portfolio a higher risk of price volatility than investments in &#8220;undervalued&#8221; companies.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Emerging Markets Risk:</b> Investments in or exposure to investments in emerging markets, such as those in Latin America, Asia, the Middle East, Eastern Europe and Africa, may be riskier than developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, political and economic instability, less governmental regulation of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value ofa foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Interest Rate Risk:</b> Values of debt securities fluctuate as interest rates change. Debt securities with longer durations or fixed interest rates tend to be more sensitive to changes in interest rates, making them more volatile than debt securities with shorter durations or floating or adjustable interest rates.</p><p><b>&#8226; Credit Risk:</b> An issuer or guarantor of a debt instrument might be unable or unwilling to meet its financial obligations.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p> <p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p> <p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p> <p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p> <p><b>&#8226; Growth Companies Risk:</b> Growth companies have the potential for above average or rapid growth but may give the portfolio a higher risk of price volatility than investments in &#8220;undervalued&#8221; companies.</p> <p><b>&#8226; Small Number of Holdings Risk:</b> A portfolio with a small number of holdings may have greater exposure to those holdings which could increase potential price volatility compared to portfolios with a greater number of holdings.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be You would pay the following expenses if you did not redeem your shares The Example does not reflect sales charges (loads) on reinvested dividends [and other distributions]. If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other nonprincipal risks:</p> <p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p> <p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p> <p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p> <p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p> <p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p> <p><b>&#8226; Value Companies Risk:</b> Value companies are those that are thought to be undervalued and that a company&#8217;s stock is trading for less than its intrinsic value. There is a risk that the determination that a stock is undervalued is not correct or is not recognized in the market.</p> <p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p> <p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The manager generally considers a company to be a large-capitalization company if the company has a market capitalization similar to companies contained within the S&#038;P 500 Index. As of December 31, 2010, the market capitalization range of the S&#038;P 500 Index was approximately $1.58 billion to $368.74 billion.</p> <p>The portfolio principally invests in, and sells short, equity securities of large, publicly traded companies. Equity securities in which the portfolio invests include common stocks, depositary receipts and exchange-traded funds.</p><p>The manager intends to maintain an approximate net long exposure of 100% (long market value minus short market value) to the equity market. However, long and short positions will vary in size as market opportunities change. The portfolio&#8217;s long positions and their equivalents will generally range between 90% and 150%, and short positions will generally range between 0% and 50% of the value of the net assets in the portfolio.</p> <p>The manager will establish long equity positions in securities that the manager believes will outperform the market and will take short positions in equity securities the manager believes will underperform the market. When a short sale occurs, the portfolio will arrange through and pay a broker to borrow the security for delivery to the buyer. When the portfolio borrows a security, it is obligated to replace the security borrowed at its market price at the time of replacement. The portfolio will utilize securities lending to finance the costs of (i) purchasing long positions in excess of the value of the portfolio&#8217;s assets and (ii) borrowing securities sold short. The cost of financing long positions in excess of the value of the portfolio&#8217;s assets and of borrowing securities sold short and associated costs with this strategy are interest and/or transactional costs of the portfolio. Accordingly, the portfolio will be leveraged and could have more equity exposure than a portfolio that does not engage in this strategy. However, the portfolio intends to maintain an approximate net 100% long exposure.

Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p> <p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer. The portfolio seeks to balance investments among different types of investments and strategies in an attempt to manage risks. However, this strategy is still subject to price volatility and may lose money, particularly during periods of broad market declines.</p> <p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p> <p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p> <p><b>&#8226; Short Sale Risk:</b> A short sale involves the risk that the price at which the portfolio purchases a security to replace the borrowed security may be higher than the price that the portfolio sold the security, resulting in a loss to the portfolio. Such loss is theoretically unlimited. Short sales also involve certain costs and may expose the portfolio to <i>leverage risk.</i></p> <p><b>&#8226; Leverage Risk:</b> Leverage is investment exposure which exceeds the initial amount invested. Leverage can cause the portfolio to lose more than the principal amount invested. Leverage can magnify the portfolio&#8217;s gains and losses and therefore increase its volatility.</p> <p><b>&#8226; Securities Lending Risk:</b> When the portfolio loans securities to brokers, dealers or financial institutions, there is a risk of delay in the return of the securities loaned. All loans are secured by collateral which is held by the custodian. The portfolio retains beneficial ownership and all economic benefits of a loaned security other than the ability to vote a proxy for that security while out on loan.</p> <p><b>&#8226; Borrowing Risk:</b> Borrowing money to finance purchases of securities that exceed a portfolio&#8217;s net assets creates <i>leverage.</i> This may exaggerate changes in the net asset value of the portfolio&#8217;s shares and its returns. The portfolio bears the added market risk of the securities purchased. Borrowing will cost a portfolio interest expense and other fees and may reduce its returns.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The portfolio may be affected by the following principal risks, among other nonprincipal risks:</p> <p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p> <p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p> <p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p> <p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p> <p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p> <p><b>&#8226; Small Number of Holdings Risk:</b> A portfolio with a small number of holdings may have greater exposure to those holdings which could increase potential price volatility compared to portfolios with a greater number of holdings.</p> <p><b>&#8226; Growth Companies Risk:</b> Growth companies have the potential for above average or rapid growth but may give the portfolio a higher risk of price volatility than investments in &#8220;undervalued&#8221; companies.</p> <p><b>&#8226; Value Companies Risk:</b> Value companies are those that are thought to be undervalued and that a company&#8217;s stock is trading for less than its intrinsic value. There is a risk that the determination that a stock is undervalued is not correct or is not recognized in the market.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be You would pay the following expenses if you did not redeem your shares The Example does not reflect sales charges (loads) on reinvested dividends [and other distributions]. If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio).

Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p> <p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p> <p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p> <p><b>&#8226; Mid-Capitalization Companies Risk:</b> Mid-capitalization companies may be riskier and more susceptible to price swings than larger companies.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be You would pay the following expenses if you did not redeem your shares The Example does not reflect sales charges (loads) on reinvested dividends [and other distributions]. If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other nonprincipal risks:</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p> <p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p> <p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b> &#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p> <p><b>&#8226; Mid-Capitalization Companies Risk:</b> Mid-capitalization companies may be riskier and more susceptible to price swings than larger companies. Mid-capitalization companies may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger, more established companies.</p> <p><b>&#8226; Growth Companies Risk:</b> Growth companies have the potential for above average or rapid growth but may give the portfolio a higher risk of price volatility than investments in &#8220;undervalued&#8221; companies.</p> <p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p> <p><b>&#8226; Emerging Markets Risk:</b> Investments in or exposure to investments in emerging markets, such as those in Latin America, Asia, the Middle East, Eastern Europe and Africa, may be riskier than developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, political and economic instability, less governmental regulation of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.</p> <p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be You would pay the following expenses if you did not redeem your shares The Example does not reflect sales charges (loads) on reinvested dividends [and other distributions]. If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio).

The portfolio may be affected by the following principal risks, among other nonprincipal risks:</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. raditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events. </p><p><b>&#8226; Mid-Capitalization Companies Risk:</b> Mid-capitalization companies may be riskier and more susceptible to price swings than larger companies. Mid-capitalization companies may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger, more established companies. </p><p><b>&#8226; Value Companies Risk:</b> Value companies are those that are thought to be undervalued and that a company&#8217;s stock is trading for less than its intrinsic value. There is a risk that the determination that a stock is undervalued is not correct or is not recognized in the market.</p><p><b> &#8226; Equity Initial Public Offering (IPO) Risk:</b> Investments in equity IPOs may be more volatile than investments in other equity securities and may expose the portfolio to risks associated with companies that have short operating histories and less-established market sectors.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Each manager has its own investment style and acts independently of the other. Franklin is an active manager; BlackRock is an index manager and will not actively manage its portion of the portfolio. PLFA, the investment adviser, allocates the portfolio&#8217;s assets between Franklin and BlackRock. PLFA will normally strive to allocate inflows and outflows between the two managers with a 70% allocation to Franklin and a 30% allocation to BlackRock, but may change the allocation or rebalance at any time. The relative values of each manager&#8217;s share of the portfolio&#8217;s assets also may change over time.</p><p> The portfolio invests at least 80% of its assets in securities of companies with small market capitalizations, including instruments with characteristics of small-capitalization equity securities (such as derivatives). The managers generally consider a company to be a small-capitalization company if it has a market capitalization that is no more than: (1) the largest market capitalization of a company in the Russell 2000 Value Index as of the most recent month-end; or (2) the average of the month-end largest market capitalization of a company in the Russell 2000 Value Index over the prior 12 months.

The Russell 2000 Value Index measures the performance of the small-capitalization value segment of the U.S. equity universe. It includes those Russell 2000 companies with lower price-to-book ratios and lower forecasted growth values. The manager principally invests in common stock.</p><p> The portfolio will generally hold any number of the stocks in the index and tries to match its sector weightings and characteristics. The manager periodically reviews and rebalances the portfolio&#8217;s investments to more closely track the performance of the index.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non-principal risks:</p><p><b><i>Franklin managed portion</i></b></p> <p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p> <p><b><i>BlackRock managed portion</i></b></p> <p><b>&#8226; Tracking Error Risk:</b> Performance of the portfolio may vary substantially from the performance of the portfolio&#8217;s benchmark index due to imperfect correlation between the portfolio&#8217;s investments and the index.</p> <p><b><i>Additional principal risks</i></b></p> <p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p> <p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b> &#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p> <p><b>&#8226; Small-Capitalization Companies Risk:</b> Small-capitalization companies may be riskier and more susceptible to price swings than larger companies. Small-capitalization companies, particularly those in their developmental stages, may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger more established companies.</p> <p><b>&#8226; Value Companies Risk:</b> Value companies are those that are thought to be undervalued and that a company&#8217;s stock is trading for less than its intrinsic value. There is a risk that the determination that a stock is undervalued is not correct or is not recognized in the market.</p> <p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations. Investments in smaller companies have a greater risk of being or becoming less liquid than investments in equity securities with larger market capitalizations.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other nonprincipal risks:</p> <p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p> <p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p> <p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p> <p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p> <p><b>&#8226; Small-Capitalization Companies Risk:</b> Small-capitalization companies may be riskier and more susceptible to price swings than larger companies. Small-capitalization companies, particularly those in their developmental stages, may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger more established companies.</p> <p><b>&#8226; Growth Companies Risk:</b> Growth companies have the potential for above average or rapid growth but may give the portfolio a higher risk of price volatility than investments in &#8220;undervalued&#8221; companies.</p> <p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations. Investments in smaller companies have a greater risk of being or becoming less liquid than investments in equity securities with larger market capitalizations.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non-principal risks:</p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p><p><b>&#8226; Small-Capitalization Companies Risk:</b> Small-capitalization companies may be riskier and more susceptible to price swings than larger companies. Small-capitalization companies, particularly those in their developmental stages, may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger more established companies.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations. Investments in smaller companies have a greater risk of being or becoming less liquid than investments in equity securities with larger market capitalizations.</p><p><b>&#8226; Tracking Error Risk:</b> Performance of the portfolio may vary substantially from the performance of the portfolio&#8217;s benchmark index due to imperfect correlation between the portfolio&#8217;s investments and the index.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non-principal risks:</p> <p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p> <p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p> <p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p> <p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p> <p><b>&#8226; Dividend-Oriented Companies Risk:</b> Companies that have historically paid regular dividends to shareholders may decrease or eliminate dividend payments in the future. A decrease in dividend payments by an issuer may result in a decrease in the value of the issuer&#8217;s stock and less available capital for the portfolio.</p> <p><b>&#8226; Small-Capitalization Companies Risk:</b> Small-capitalization companies may be riskier and more susceptible to price swings than larger companies. Small-capitalization companies, particularly those in their developmental stages, may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger more established companies.</p> <p><b>&#8226; Value Companies Risk:</b> Value companies are those that are thought to be undervalued and that a company&#8217;s stock is trading for less than its intrinsic value. There is a risk that the determination that a stock is undervalued is not correct or is not recognized in the market.</p> <p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations. Investments in smaller companies have a greater risk of being or becoming less liquid than investments in equity securities with larger market capitalizations.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non-principal risks:</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Industry and Sector Concentration Risk:</b> Concentrating investments in a single industry or market sector makes the portfolio more susceptible to adverse economic, business, regulatory or other developments affecting that industry or sector.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p><p><b>&#8226; Small-Capitalization Companies Risk: </b>Small-capitalization companies may be riskier and more susceptible to price swings than larger companies. Small-capitalization companies, particularly those in their developmental stages, may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger more established companies.</p><p><b>&#8226; Mid-Capitalization Companies Risk:</b> Mid-capitalization companies may be riskier and more susceptible to price swings than larger companies. Mid-capitalization companies may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger, more established companies.</p><p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations.</p><p><b>&#8226; Regulatory Impact Risk: </b>Some sectors are subject to extensive government regulation, which may change frequently and impact the value of the portfolio significantly.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Emerging Markets Risk:</b> Investments in or exposure to investments in emerging markets, such as those in Latin America, Asia, the Middle East, Eastern Europe and Africa, may be riskier than developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, political and economic instability, less governmental regulation of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non- principal risks:</p> <p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p> <p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p> <p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p> <p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p> <p><b>&#8226; Industry and Sector Concentration Risk:</b> Concentrating investments in a single industry or market sector makes the portfolio more susceptible to adverse economic, business, regulatory or other developments affecting that industry or sector.</p> <p><b>&#8226; Real Estate Risk:</b> Adverse changes in the real estate markets, such as fluctuations in property value; property damage or destruction; tenant or borrower default; taxes; and other economic, political or regulatory events may affect the value of the Investments in real estate investment trusts (REITs) and real estate operating companies (REOCs).</p> <p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p> <p><b>&#8226; Mid-Capitalization Companies Risk:</b> Mid-capitalization companies may be riskier and more susceptible to price swings than larger companies. Mid-capitalization companies may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger, more established companies.</p> <p><b>&#8226; Small-Capitalization Companies Risk:</b> Small capitalization companies may be riskier and more susceptible to price swings than larger companies. Small-capitalization companies, particularly those in their developmental stages, may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger more established companies.</p> <p><b>&#8226; Small Number of Holdings Risk:</b> A portfolio with a small number of holdings may have greater exposure to those holdings which could increase potential price volatility compared to portfolios with a greater number of holdings.</p> <p><b>&#8226; Non-Diversification Risk:</b> The portfolio is classified as non-diversified and may invest a greater percentage of its assets in a single issuer or a fewer number of issuers than a diversified portfolio. This increases potential price volatility and the risk that its value could go down because of the poor performance of a single investment or a small number of investments.</p> <p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non- principal risks:</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Industry and Sector Concentration Risk:</b> Concentrating investments in a single industry or market sector makes the portfolio more susceptible to adverse economic, business, regulatory or other developments affecting that industry or sector.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p><p><b>&#8226; Mid-Capitalization Companies Risk:</b> Mid-capitalization companies may be riskier and more susceptible to price swings than larger companies. Mid-capitalization companies may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger, more established companies.</p><p><b>&#8226; Small-Capitalization Companies Risk:</b> Small-capitalization companies may be riskier and more susceptible to price swings than larger companies. Small-capitalization companies, particularly those in their developmental stages, may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger more established companies.</p><p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations. Investments in smaller companies have a greater risk of being or becoming less liquid than investments in equity securities with larger market capitalizations.</p><p><b>&#8226; Regulatory Impact Risk:</b> Some sectors are subject to extensive government regulation, which may change frequently and impact the value of the portfolio significantly.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Emerging Markets Risk:</b> Investments in or exposure to investments in emerging markets, such as those in Latin America, Asia, the Middle East, Eastern Europe and Africa, may be riskier than developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, political and economic instability, less governmental regulation of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.</p><p><b>&#8226; Small Number of Holdings Risk:</b> A portfolio with a small number of holdings may have greater exposure to those holdings which could increase potential price volatility compared to portfolios with a greater number of holdings.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The portfolio may be affected by the following principal risks, among other non- principal risks:</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Emerging Markets Risk:</b> Investments in or exposure to investments in emerging markets, such as those in Latin America, Asia, the Middle East, Eastern Europe and Africa, may be riskier than developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, political and economic instability, less governmental regulation of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Geographic Concentration Risk:</b> Concentrating investments in a single country, a limited number of countries, or a particular geographic region makes the portfolio more susceptible to adverse economic, political, social, regulatory and other developments in that country, countries or region.</p><p><b>&#8226; Growth Companies Risk:</b> Growth companies have the potential for above average or rapid growth but may give the portfolio a higher risk of price volatility than investments in &#8220;undervalued&#8221; companies.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non- principal risks:</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p><p><b>&#8226; Growth Companies Risk:</b> Growth companies have the potential for above average or rapid growth but may give the portfolio a higher risk of price volatility than investments in &#8220;undervalued&#8221; companies.</p><p><b>&#8226; Value Companies Risk:</b> Value companies are those that are thought to be undervalued and that a company&#8217;s stock is trading for less than its intrinsic value. There is a risk that the determination that a stock is undervalued is not correct or is not recognized in the market.</p><p><b>&#8226; Emerging Markets Risk:</b> Investments in or exposure to investments in emerging markets, such as those in Latin America, Asia, the Middle East, Eastern Europe and Africa, may be riskier than developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, political and economic instability, less governmental regulation of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.</p><p><b>&#8226; Geographic Concentration Risk:</b> Concentrating investments in a single country, a limited number of countries, or a particular geographic region makes the portfolio more susceptible to adverse economic, political, social, regulatory and other developments in that country, countries or region.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non- principal risks:</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Small-Capitalization Companies Risk:</b> Small-capitalization companies may be riskier and more susceptible to price swings than larger companies. Small-capitalization companies, particularly those in their developmental stages, may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger more established companies.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations.</p><p><b>&#8226; Geographic Concentration Risk:</b> Concentrating investments in a single country, a limited number of countries, or a particular geographic region makes the portfolio more susceptible to adverse economic, political, social, regulatory and other developments in that country, countries or region.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non- principal risks:</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Geographic Concentration Risk:</b> Concentrating investments in a single country, a limited number of countries, or a particular geographic region makes the portfolio more susceptible to adverse economic, political, social, regulatory and other developments in that country, countries or region.</p><p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p><p><b>&#8226; Value Companies Risk:</b> Value companies are those that are thought to be undervalued and that a company&#8217;s stock is trading for less than its intrinsic value. There is a risk that the determination that a stock is undervalued is not correct or is not recognized in the market.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Although the Master Asset Allocation Fund focuses on investments in medium to larger capitalization companies, the Master Asset Allocation Fund&#8217;s investments are not limited to a particular capitalization size. The Master Asset Allocation Fund may invest up to 15% of its assets in common stocks and other equity securities of issuers domiciled outside the United States and up to 5% of its assets in debt securities of issuers domiciled outside the United States.</p><p> In seeking to pursue its investment goal, the Master Asset Allocation Fund will vary its mix of equity securities, debt securities and money market instruments. Under normal market conditions, the manager expects, (but is not required) to maintain an investment mix falling within the following ranges: 40% to 80% in equity securities, 20% to 50% in debt securities and 0% to 40% in money market instruments. As of December 31, 2010, the Master Asset Allocation Fund was approximately 76% invested in equity securities, 21% invested in debt securities and 3% invested in money market instruments. The proportion of equities, debt and money market securities held by the Master Asset Allocation Fund will vary with market conditions and the manager&#8217;s assessment of their relative attractiveness as investment opportunities.</p><p> The Master Asset Allocation Fund may also invest up to 25% of its debt assets in lower quality debt securities. Such securities are sometimes referred to as &#8220;junk bonds.&#8221;</p><p> The basic investment philosophy of the Master Asset Allocation Fund manager is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. The manager believes that an important way to accomplish this is through fundamental analysis, which may include meeting with company executives and employees, suppliers, customers and competitors.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non- principal risks:</p><p><b> &#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b> Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b> &#8226; Price Volatility Risk:</b> The market value of the portfolio's investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer. The volatility of non-investment grade debt securities (including loans) may be greater than for investment grade securities.</p><p><b> &#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p><p><b> &#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p><p><b> &#8226; Mid-Capitalization Companies Risk:</b> Mid-capitalization companies may be riskier and more susceptible to price swings than larger companies. Mid-capitalization companies may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger, more established companies.</p><p><b> &#8226; Growth Companies Risk:</b> Growth companies have the potential for above average or rapid growth but may give the portfolio a higher risk of price volatility than investments in &#8220;undervalued&#8221; companies.</p><p><b>&#8226; Dividend Oriented Companies Risk:</b> Companies that have historically paid regular dividends to shareholders may decrease or eliminate dividend payments in the future. A decrease in dividend payments by an issuer may result in a decrease in the value of the issuer&#8217;s stock and less available capital for the portfolio.</p><p><b>&#8226; Interest Rate Risk:</b> Values of debt securities fluctuate as interest rates change. Debt securities with longer durations or fixed interest rates tend to be more sensitive to changes in interest rates, making them more volatile than debt securities with shorter durations or floating or adjustable interest rates.</p><p><b> &#8226; Credit Risk:</b> An issuer or guarantor of a debt instrument might be unable or unwilling to meet its financial obligations.</p><p><b> &#8226; U.S. Government Securities Risk:</b> Not all U.S. government securities are backed or guaranteed by the U.S. government. There is risk that the U.S. government will not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law.</p><p><b> &#8226; High-Yield or &#8220;Junk&#8221; Securities Risk:</b> High yield securities are typically issued by companies that are highly leveraged, less creditworthy or financially distressed and are considered to be mostly speculative in nature (high risk), are potentially less liquid, and have a greater risk of loss, that is they are more likely to default than higher rated securities.</p><p><b> &#8226; Mortgage-Related and Other Asset-Backed Securities Risk:</b> Mortgage-related and other asset-backed securities are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the market for the assets underlying such securities. As a result, during periods of declining asset value, difficult or frozen credit markets, swings in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to extension risk, where issuers may pay principal later than expected, and prepayment risk, where issuers may pay principal more quickly than expected, causing proceeds to be reinvested at lower prevailing interest rates.</p><p><b> &#8226; Asset Allocation Strategies Risk:</b> Seek to balance investments among different types of investments and strategies in an attempt to manage risks. This type of strategy is still subject to price volatility and can still lose money, particularly during periods of broad market declines.</p><p><b> &#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b> &#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Master/Feeder Mutual Fund Structure:</b> The portfolio bears the fees and expenses of the Master Fund in addition to its own fees and expenses, which could result in a higher overall expense ratio.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The portfolio aims to provide diversification across major asset classes &#8212; U.S. stocks, international stocks, and bonds &#8212; by investing primarily in Class P shares of other Pacific Select Fund portfolios (each, an &#8220;Acquired Fund&#8221; or &#8220;Underlying Portfolio&#8221; or collectively, &#8220;Underlying Portfolios&#8221;). Each Underlying Portfolio invests directly in equity securities, bonds or other securities, as appropriate, consistent with its investment objective and strategies. A majority of the Underlying Portfolios are index portfolios, which means they seek to match the investment returns of specified stock or bond indexes. The portfolio also invests in certain Underlying Portfolios that are not index portfolios. Although the portfolio seeks to provide diversification across major asset classes, it may invest a significant portion of its assets in any one Underlying Portfolio.</p><p> Through investments in the Underlying Portfolios, this portfolio invests heavily in debt securities, principally investment grade securities, including mortgage-related securities and also invests a considerable portion of its assets in equity securities such as common stocks of U.S. and international companies. As of the date of this prospectus, the portfolio&#8217;s target asset class allocations are 60% of its assets to fixed income, 29% to domestic equity and 11% to international equity.</p><div style="font-face: arial; font-size:8pt" align="left"><b>Underlying Portfolio Allocation Targets</b> <i>(as of 5/1/11)</i></div><table style="font-size:8pt;margin-top:8pt" cellpadding="0" cellspacing="0" border="0" width="100%"><tr style="font-size:0pt"><td width="50%">&nbsp;</td><td width="50%">&nbsp;</td></tr><tr><td> PD Aggregate Bond Index</td><td> 54%</td></tr><tr><td> PD High Yield Bond Market</td><td> 6%</td></tr><tr><td> PD Large-Cap Growth Index</td><td> 11%</td></tr><tr><td> PD Large-Cap Value Index</td><td> 13%</td></tr><tr><td> PD Small-Cap Growth Index</td><td> 2%</td></tr><tr><td> PD Small-Cap Value Index</td><td> 3%</td></tr><tr><td> PD International Large-Cap</td><td> 10%</td></tr><tr><td> PD Emerging Markets</td><td> 1%</td></tr></table><p><i>Although the portfolios expects to be fully invested at all times, itmay maintain liquidity reserves to meet redemption requests.</i></p><p>PLFA regularly reviews the portfolio&#8217;s allocations to determine whether rebalancing is appropriate and may use cash flows to help implement target allocations and rebalancing.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non- principal risks:</p><p><b>&#8226; Asset Allocation Fund of Funds Risk:</b> Typically, the fund of funds are exposed to the same risks as the Underlying Portfolios in direct proportion to the allocation of assets among those portfolios. Allocations among the Underlying Portfolios are determined using an asset allocation process, which seeks to optimize returns by allocating among different asset classes given various levels of risk tolerance. The theory behind asset allocation is that diversification among asset classes can help reduce volatility over the long-term, which assumes that asset classes may not move in tandem and that positive returns in one or more classes will help offset negative returns in other asset classes, although you still may lose money and/or experience volatility, particularly during periods of broad market declines. Market and asset class performance may differ in the future from the historical performance and from the assumptions used to develop the allocations. There&#8217;s a risk that you could achieve better returns by investing in anindividual portfolio or portfolios representing a single asset class rather than using asset allocation.</p><p><b>&#8226; Potential Conflicts of Interest Risk:</b> PLFA may be subject to competing interests that have the potential to influence its investment decisions for the portfolio. For example, PLFA may be influenced by its view of the best interests of underlying portfolios, such as a view that an underlying portfolio may benefit from additional assets or could be harmed by redemptions. In addition, PLFA may be influenced by the insurance companies which use the asset allocation portfolios as investment vehicles for their variable life and annuity products in terms of how the asset allocation portfolios are managed and their risk profiles.</p><p> Principal risks from holdings in Underlying Portfolios</p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b> Tracking Error Risk:</b> Performance of the portfolio may vary substantially from the performance of the portfolio&#8217;s benchmark index due to imperfect correlation between the portfolio&#8217;s investments and the index.</p><p><b>&#8226; Index Sampling Risk:</b> Index sampling risk is the chance that the securities selected for the Fund, in the aggregate, will not provide investment performance matching that of the Fund&#8217;s target index.</p><p><b> Credit Risk:</b> An issuer or guarantor of a debt instrument might be unable or unwilling to meet its financial obligations.</p><p><b> Interest Rate Risk:</b> Values of debt securities fluctuate as interest rates change. Debt securities with longer durations or fixed interest rates tend to be more sensitive to changes in interest rates, making them more volatile than debt securities with shorter durations or floating or adjustable interest rates.</p><p><b>&#8226; U.S. Government Securities Risk:</b> Not all U.S. government securities are backed or guaranteed by the U.S. government. There is risk that the U.S. government will not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law.</p><p><b>&#8226; Mortgage-Related and Other Asset-Backed Securities Risk:</b> Mortgage-related and other asset-backed securities are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the market for the assets underlying such securities. As a result, during periods of declining asset value, difficult or frozen credit markets, swings in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to extension risk, where issuers may pay principal later than expected, and prepayment risk, where issuers may pay principal more quickly than expected, causing proceeds to be reinvested at lower prevailing interest rates.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations. Investments in smaller companies have a greater risk of being or becoming less liquid than investments in equity securities with larger market capitalizations.</p><p><b>&#8226; Forward Commitments Risk:</b> Fixed income securities may be purchased on a &#8220;forward commitment&#8221; or &#8220;when-issued&#8221; basis (meaning securities are purchased or sold with payment and delivery taking place in the future). In forward commitment or when-issued transactions, if the seller or buyer, as the case may be, fails to consummate the transaction, the counterparty may miss the opportunity of obtaining a price or yield considered to be advantageous.</p><p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p><p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p><p><b>&#8226; Value Companies Risk:</b> Value companies are those that are thought to be undervalued and that a company&#8217;s stock is trading for less than its intrinsic value. There is a risk that the determination that a stock is undervalued is not correct or is not recognized in the market.</p><p><b>&#8226; Growth Companies Risk:</b> Growth companies have the potential for above average or rapid growth but may give the portfolio a higher risk of price volatility than investments in &#8220;undervalued&#8221; companies.</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Geographic Concentration Risk:</b> Concentrating investments in a single country, a limited number of countries, or a particular geographic region makes the portfolio more susceptible to adverse economic, political, social, regulatory and other developments in that country, countries or region.</p><p><b> Companies Traded Over-The-Counter Risk:</b> Companies traded over-the-counter (OTC) trade less frequently and in smaller volumes than exchange-listed stocks and may experience greater price volatility than exchange-listed stocks.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

If the Fund provides this disclosure, also disclose the period for which the expense reimbursement or fee waiver arrangement is expected to continue, and briefly describe who can terminate the arrangement and under what circumstances.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Paragraph 1 -Subparagraph 11 -Subsection table falsefalseLess expense reimbursements0rr_FeeWaiverOrReimbursementOverAssetstruefalsefalsefalsefalsefalsefalsefalsefalsefalsefalse[2]1falsefalsefalse00falsefalsefalsefalsefalse2truetruetrue-0.0010-0.0010falsefalsefalsetruefalseOthernanafalsefalseLess expense reimbursements8falseRowprimaryElement*11false0rr_NetExpensesOverAssetsrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseterselabel1falsetruetrue00falsefalsefalsetruefalse2truetruetrue0.00590.0059falsefalsefalsetruefalseOtherrr:NonNegativePure4TypepureTotal Annual Fund Operating Expenses.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Paragraph 1 -Subparagraph 11 -Subsection table falsefalseTotal annual operating expenses after expense reimbursements0rr_NetExpensesOverAssetstruefalsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsefalsefalse2truetruetrue0.00590.0059falsefalsefalsetruefalseOthernanafalsefalseTotal annual operating expenses after expense reimbursements1Expense information in the table has been restated to reflect current fees.2The investment adviser has contractually agreed to reimburse the portfolio to the extent the total net expenses (excluding extraordinary expenses) exceed 0.59%, through April 30, 2014.

Each Underlying Portfolio invests directly in equity securities, bonds or other securities, as appropriate, consistent with its investment objective and strategies. A majority of the Underlying Portfolios are index portfolios, which means they seek to match the investment returns of specified stock or bond indexes.

Although the portfolio seeks to provide diversification across major asset classes, it may invest a significant portion of its assets in any Underlying Portfolio.</p><p>Through investments in the Underlying Portfolios, this portfolio invests heavily in equity securities, principally in common stocks of U.S. and international companies, but also invests a considerable portion of its assets in debt securities, such as investment grade securities, including mortgage-related securities.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non- principal risks:</p><p><b>&#8226; Asset Allocation Fund of Funds Risk:</b> Typically, the fund of funds are exposed to the same risks as the Underlying Portfolios in direct proportion to the allocation of assets among those portfolios. Allocations among the Underlying Portfolios are determined using an asset allocation process, which seeks to optimize returns by allocating among different asset classes given various levels of risk tolerance. The theory behind asset allocation is that diversification among asset classes can help reduce volatility over the long-term, which assumes that asset classes may not move in tandem and that positive returns in one or more classes will help offset negative returns in other asset classes, although you still may lose money and/or experience volatility, particularly during periods of broad market declines. Market and asset class performance may differ in the future from the historical performance and from the assumptions used to develop the allocations. There&#8217;s a risk that you could achieve better returns by investing in an individual portfolio or portfolios representing a single asset class rather than using asset allocation.</p><p><b>&#8226; Potential Conflicts of Interest Risk:</b> PLFA may be subject to competing interests that have the potential to influence its investment decisions for the portfolio. For example, PLFA may be influenced by its view of the best interests of underlying portfolios, such as a view that an underlying portfolio may benefit from additional assets or could be harmed by redemptions. In addition, PLFA may be influenced by the insurance companies which use the asset allocation portfolios as investment vehicles for their variable life and annuity products in terms of how the asset allocation portfolios are managed and their risk profiles.</p><p><b>Principal risks from holdings in Underlying Portfolios</b></p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer. The portfolio seeks to balance investments among different types of investments and strategies in an attempt to manage risks. However, this strategy is still subject to price volatility and may lose money, particularly during periods of broad market declines. The volatility of non-investment grade debt securities (including loans) may be greater than for investment grade securities.</p><p><b>&#8226; Tracking Error Risk:</b> Performance of the portfolio may vary substantially from the performance of the portfolio&#8217;s benchmark index due to imperfect correlation between the portfolio&#8217;s investments and the index.</p><p><b>&#8226; Index Sampling Risk:</b> Index sampling risk is the chance that the securities selected for the Fund, in the aggregate, will not provide investment performance matching that of the Fund&#8217;s target index.</p><p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p><p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p><p><b>&#8226; Credit Risk:</b> An issuer or guarantor of a debt instrument might be unable or unwilling to meet its financial obligations.</p><p><b>&#8226; Interest Rate Risk:</b> Values of debt securities fluctuate as interest rates change. Debt securities with longer durations or fixed interest rates tend to be more sensitive to changes in interest rates, making them more volatile than debt securities with shorter durations or floating or adjustable interest rates.</p><p><b>&#8226; U.S. Government Securities Risk:</b> Not all U.S. government securities are backed or guaranteed by the U.S. government. There is risk that the U.S. government will not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law.</p><p><b>&#8226; Mortgage-Related and Other Asset-Backed Securities Risk:</b> Mortgage-related and other asset-backed securities are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the market for the assets underlying such securities. As a result, during periods of declining asset value, difficult or frozen credit markets, swings in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to extension risk, where issuers may pay principal later than expected, and prepayment risk, where issuers may pay principal more quickly than expected, causing proceeds to be reinvested at lower prevailing interest rates.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations.</p><p><b>&#8226; Forward Commitments Risk:</b> Fixed income securities may be purchased on a &#8220;forward commitment&#8221; or &#8220;when-issued&#8221; basis (meaning securities are purchased or sold with payment and delivery taking place in the future). In forward commitment or when-issued transactions, if the seller or buyer, as the case may be, fails to consummate the transaction, the counterparty may miss the opportunity of obtaining a price or yield considered to be advantageous.</p><p><b>&#8226; Value Companies Risk:</b> Value companies are those that are thought to be undervalued and that a company&#8217;s stock is trading for less than its intrinsic value. There is a risk that the determination that a stock is undervalued is not correct or is not recognized in the market.</p><p><b>&#8226; Growth Companies Risk:</b> Growth companies have the potential for above average or rapid growth but may give the portfolio a higher risk of price volatility than investments in &#8220;undervalued&#8221; companies.</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Geographic Concentration Risk:</b> Concentrating investments in a single country, a limited number of countries, or a particular geographic region makes the portfolio more susceptible to adverse economic, political, social, regulatory and other developments in that country, countries or region.</p><p><b>&#8226; Companies Traded Over-The-Counter Risk:</b> Companies traded over-the-counter (OTC) trade less frequently and in smaller volumes than exchange-listed stocks and may experience greater price volatility than exchange-listed stocks.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The portfolio aims to provide diversification across major asset classes &#8212; U.S. stocks, international stocks, and bonds &#8212; by investing primarily in Class P shares of other Pacific Select Fund portfolios (each, an &#8220;Acquired Fund&#8221; or &#8220;Underlying Portfolio&#8221; or collectively, &#8220;Underlying Portfolios&#8221;). Each Underlying Portfolio invests directly in equity securities, bonds or other securities, as appropriate, consistent with its investment objective and strategies. A majority of the Underlying Portfolios are index portfolios, which means they seek to match the investment returns of specified stock or bond indexes. The portfolio also invests in certain Underlying Portfolios that are not index portfolios. Although the portfolio seeks to provide diversification across major asset classes, it may invest a significant portion of its assets in any Underlying Portfolio.</p><p>Through investments in the Underlying Portfolios, this portfolio invests very heavily in equity securities, principally in common stocks of U.S. and international companies, but also invests a portion of its assets in debt securities, such as investment grade securities, including mortgage-related securities.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non-principal risks:</p><p><b>&#8226; Asset Allocation Fund of Funds Risk:</b> Typically, the fund of funds are exposed to the same risks as the Underlying Portfolios in direct proportion to the allocation of assets among those portfolios. Allocations among the Underlying Portfolios are determined using an asset allocation process, which seeks to optimize returns by allocating among different asset classes given various levels of risk tolerance. The theory behind asset allocation is that diversification among asset classes can help reduce volatility over the long-term, which assumes that asset classes may not move in tandem and that positive returns in one or more classes will help offset negative returns in other asset classes, although you still may lose money and/or experience volatility, particularly during periods of broad market declines. Market and asset class performance may differ in the future from the historical performance and from the assumptions used to develop the allocations. There&#8217;s a risk that you could achieve better returns by investing in an individual portfolio or portfolios representing a single asset class rather than using asset allocation.</p><p><b>&#8226; Potential Conflicts of Interest Risk:</b> PLFA may be subject to competing interests that have the potential to influence its investment decisions for the portfolio. For example, PLFA may be influenced by its view of the best interests of underlying portfolios, such as a view that an underlying portfolio may benefit from additional assets or could be harmed by redemptions. In addition, PLFA may be influenced by the insurance companies which use the asset allocation portfolios as investment vehicles for their variable life and annuity products in terms of how the asset allocation portfolios are managed and their risk profiles.</p><p><b>Principal risks from holdings in Underlying Portfolios</b></p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer. The portfolio seeks to balance investments among different types of investments and strategies in an attempt to manage risks. However, this strategy is still subject to price volatility and may lose money, particularly during periods of broad market declines. The volatility of non-investment grade debt securities (including loans) may be greater than for investment grade securities.</p><p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p><p><b>&#8226; Tracking Error Risk:</b> Performance of the portfolio may vary substantially from the performance of the portfolio&#8217;s benchmark index due to imperfect correlation between the portfolio&#8217;s investments and the index.</p><p><b>&#8226; Index Sampling Risk:</b> Index sampling risk is the chance that the securities selected for the Fund, in the aggregate, will not provide investment performance matching that of the Fund&#8217;s target index.</p><p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p><p><b>&#8226; Value Companies Risk:</b> Value companies are those that are thought to be undervalued and that a company&#8217;s stock is trading for less than its intrinsic value. There is a risk that the determination that a stock is undervalued is not correct or is not recognized in the market.</p><p><b>&#8226; Growth Companies Risk:</b> Growth companies have the potential for above average or rapid growth but may give the portfolio a higher risk of price volatility than investments in &#8220;undervalued&#8221; companies.</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Geographic Concentration Risk:</b> Concentrating investments in a single country, a limited number of countries, or a particular geographic region makes the portfolio more susceptible to adverse economic, political, social, regulatory and other developments in that country, countries or region.</p><p><b>&#8226; Companies Traded Over-The-Counter Risk:</b> Companies traded over-the-counter (OTC) trade less frequently and in smaller volumes than exchange-listed stocks and may experience greater price volatility than exchange-listed stocks.</p><p><b>&#8226; Credit Risk:</b> An issuer or guarantor of a debt instrument might be unable or unwilling to meet its financial obligations.</p><p><b>&#8226; U.S. Government Securities Risk:</b> Not all U.S. government securities are backed or guaranteed by the U.S. government. There is risk that the U.S. government will not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligatedto do so by law.</p><p><b>&#8226; Mortgage-Related and Other Asset-Backed Securities Risk:</b> Mortgage-related and other asset-backed securities are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the market for the assets underlying such securities. As a result, during periods of declining asset value, difficult or frozen credit markets, swings in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to extension risk, where issuers may pay principal later than expected, and prepayment risk, where issuers may pay principal more quickly than expected, causing proceeds to be reinvested at lower prevailing interest rates.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to takeadvantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securitiesat a loss if it is required to raise cash to conduct its operations.</p><p><b>&#8226; Interest Rate Risk:</b> Values of debt securities fluctuate as interest rates change. Debt securities with longer durations or fixed interest rates tend to be more sensitive to changes in interest rates, making them more volatile than debt securities with shorter durations or floating or adjustable interest rates.</p><p><b>&#8226; Forward Commitments Risk:</b> Fixed income securities may be purchased on a &#8220;forward commitment&#8221; or &#8220;when-issued&#8221; basis (meaning securities are purchased or sold with payment and delivery taking place in the future). In forward commitment or when-issued transactions, if the seller or buyer, as the case may be, fails to consummate the transaction, the counterparty may miss the opportunity of obtaining a price or yield considered to be advantageous.</p><p><b>&#8226; Small Capitalization Companies Risk:</b> Small-capitalization companies may be riskier and more susceptible to price swings than larger companies. Small-capitalization companies, particularly those in their developmental stages, may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger more established companies.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The portfolio aims to provide diversification across major asset classes &#8211; cash equivalents, fixed income, domestic equity, and international equity &#8211; by investing primarily in Class P shares of other Pacific Select Fund portfolios (each, an &#8220;Acquired Fund&#8221; or &#8220;Underlying Portfolio&#8221; or collectively, the &#8220;Underlying Portfolios&#8221;). Each Underlying Portfolio invests directly in equity securities, bonds or other securities, as appropriate, consistent with its investment objective and strategies. The portfolio may invest a significant portion of its assets in any Underlying Portfolio.</p><p>Through investments in the Underlying Portfolios, this portfolio invests primarily in fixed income, such as investment grade securities, including mortgage-related and international securities, and derivatives, but also invests a portion of its assets in equity securities. As of the date of this prospectus, the portfolio&#8217;s target asset class allocations are 7% of its assets to cash equivalents, 73% to fixed income, 15% to domestic equity and 5% to international equity.

There is no guarantee that the portfolio will achieve its investment objective. There may be some losses in the values of the investment as asset values fluctuate. The value of your portfolio shares will fluctuate and you could lose money. The portfolio may be affected by the following principal risks, among other non-principal risks:</p><p><b>&#8226; Asset Allocation Fund of Funds Risk:</b> Typically, the fund of funds are exposed to the same risks as the Underlying Portfolios in direct proportion to the allocation of assets among those portfolios. Allocations among the Underlying Portfolios are determined using an asset allocation process, which seeks to optimize returns by allocating among different asset classes given various levels of risk tolerance. The theory behind asset allocation is that diversification among asset classes can help reduce volatility over the long-term, which assumes that asset classes may not move in tandem and that positive returns in one or more classes will help offset negative returns in other asset classes, although you still may lose money and/or experience volatility, particularly during periods of broad market declines. Market and asset class performance may differ in the future from the historical performance and from the assumptions used to develop the allocations. There&#8217;s a risk that you could achieve better returns by investing in an individual portfolio or portfolios representing a single asset class rather than using asset allocation.</p><p><b>&#8226;Potential Conflicts of Interest Risk:</b> PLFA may be subject to competing interests that have the potential to influence its investment decisions for the portfolio. For example, PLFA may be influenced by its view of the best interests of underlying portfolios, such as a view that an underlying portfolio may benefit from additional assets or could be harmed by redemptions. In addition, PLFA may be influenced by the insurance companies which use the asset allocation portfolios as investment vehicles for their variable life and annuity products in terms of how the asset allocation portfolios are managed and their risk profiles.</p><p><b>Principal risks from holdings in Underlying Portfolios</b></p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer. The volatility of non-investment grade debt securities (including loans) may be greater than for investment grade securities.</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Credit Risk:</b> An issuer or guarantor of a debt instrument might be unable or unwilling to meet its financial obligations.</p><p><b>&#8226; Interest Rate Risk:</b> Values of debt securities fluctuate as interest rates change. Debt securities with longer durations or fixed interest rates tend to be more sensitive to changes in interest rates, making them more volatile than debt securities with shorter durations or floating or adjustable interest rates.</p><p><b>&#8226; U.S. Government Securities Risk:</b> Not all U.S. government securities are backed or guaranteed by the U.S. government. There is risk that the U.S. government will not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law.</p><p><b>&#8226; Mortgage-Related and Other Asset-Backed Securities Risk:</b> Mortgage-related and other asset-backed securities are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the market for the assets underlying such securities. As a result, during periods of declining asset value, difficult or frozen credit markets, swings in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to extension risk, where issuers may pay principal later than expected, and prepayment risk, where issuers may pay principal more quickly than expected, causing proceeds to be reinvested at lower prevailing interest rates.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations. Investments in non-investment grade debt securities (sometimes called junk bonds) and asset-backed securities have a greater risk of being or becoming less liquid than investments in other, higher-rated debt securities.</p><p><b>&#8226; Leverage Risk:</b> Leverage is investment exposure which exceeds the initial amount invested. Leverage can cause the portfolio to lose more than the principal amount invested. Leverage can magnify the portfolio&#8217;s gains and losses and therefore increase its volatility.</p><p><b>&#8226; Derivatives Risk:</b> Derivatives can be complex instruments, which may experience sudden and unpredictable changes in price or liquidity and may be difficult to value, sell or unwind. The value of derivatives is based on the value of other securities or indexes. They can also create investment exposure that is greater than their cost may suggest (known as <i>leverage risk</i>). Derivative transactions may also involve a counterparty. Such transactions are subject to the credit risk and/or the ability of the counterparty to perform in accordance with the terms of the transaction.</p><p><b>&#8226; Forward Commitments Risk:</b> Fixed income securities may be purchased on a &#8220;forward commitment&#8221; or &#8220;when issued&#8221; basis (meaning securities are purchased or sold with payment and delivery taking place in the future). In forward commitment or when-issued transactions, if the seller or buyer, as the case may be, fails to consummate the transaction, the counterparty may miss the opportunity of obtaining a price or yield considered to be advantageous.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p><p><b>&#8226; High-Yield or &#8220;Junk&#8221; Securities Risk:</b> High yield securities are typically issued by companies that are highly leveraged, less creditworthy or financially distressed and are considered to be mostly speculative in nature (high risk), are potentially less liquid, and have a greater risk of loss, that is they are more likely to default than higher rated securities.</p><p><b>&#8226; Non-Diversification Risk:</b> The portfolio is classified as non-diversified and may invest a greater percentage of its assets in a single issuer or a fewer number of issuers than a diversified portfolio. This increases potential price volatility and the risk that its value could go down because of the poor performance of a single investment or a small number of investments.</p><p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p><p><b>&#8226; Inflation-Indexed Debt Securities Risk:</b> The principal values of inflation-indexed debt securities tend to increase when inflation rises and decrease when inflation falls.</p><p><b>&#8226; Emerging Markets Risk:</b> Investments in or exposure to investments in emerging markets, such as those in Latin America, Asia, the Middle East, Eastern Europe and Africa, may be riskier than developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, political and economic instability, less governmental regulation of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.</p><p><b>&#8226; Convertible Securities Risk:</b> Convertible securities have <i>credit risk</i> and <i>interest rate risk</i> and may present less risk than investments in a company&#8217;s common stock but more risk than investments in the company&#8217;s senior debt securities.</p><p><b>&#8226; Value Companies Risk:</b> Value companies are those that are thought to be undervalued and that a company&#8217;s stock is trading for less than its intrinsic value. There is a risk that the determination that a stock is undervalued is not correct or is not recognized in the market.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds. For purposes of this Item, a "New Fund" is a Fund that does not include in Form N-1A financial statements reporting operating results or that includes financial statements for the Fund's initial fiscal year reporting operating results for a period of 6 months or less.

There is no guarantee that the portfolio will achieve its investment objective. There may be some losses in the values of the investment as asset values fluctuate. The value of your portfolio shares will fluctuate and you could lose money. The portfolio may be affected by the following principal risks, among other non-principal risks:</p><p><b>&#8226; Asset Allocation Fund of Funds Risk:</b> Typically, the fund of funds are exposed to the same risks as the Underlying Portfolios in direct proportion to the allocation of assets among those portfolios. Allocations among the Underlying Portfolios are determined using an asset allocation process, which seeks to optimize returns by allocating among different asset classes given various levels of risk tolerance. The theory behind asset allocation is that diversification among asset classes can help reduce volatility over the long-term, which assumes that asset classes may not move in tandem and that positive returns in one or more classes will help offset negative returns in other asset classes, although you still may lose money and/or experience volatility, particularly during periods of broad market declines. Market and asset class performance may differ in the future from the historical performance and from the assumptions used to develop the allocations. There&#8217;s a risk that you could achieve better returns by investing in an individual portfolio or portfolios representing a single asset class rather than using asset allocation.</p><p><b>&#8226; Potential Conflicts of Interest Risk:</b> PLFA may be subject to competing interests that have the potential to influence its investment decisions for the portfolio. For example, PLFA may be influenced by its view of the best interests of underlying portfolios, such as a view that an underlying portfolio may benefit from additional assets or could be harmed by redemptions. In addition, PLFA may be influenced by the insurance companies which use the asset allocation portfolios as investment vehicles for their variable life and annuity products in terms of how the asset allocation portfolios are managed and their risk profiles.</p><p><b>Principal risks from holdings in Underlying Portfolios</b></p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer. The volatility of non-investment grade debt securities (including loans) may be greater than for investment grade securities.</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Credit Risk:</b> An issuer or guarantor of a debt instrument might be unable or unwilling to meet its financial obligations.</p><p><b>&#8226; Interest Rate Risk:</b> Values of debt securities fluctuate as interest rates change. Debt securities with longer durations or fixed interest rates tend to be more sensitive to changes in interest rates, making them more volatile than debt securities with shorter durations or floating or adjustable interest rates.</p><p><b>&#8226; U.S. Government Securities Risk:</b> Not all U.S. government securities are backed or guaranteed by the U.S. government. There is risk that the U.S. government will not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law.</p><p><b>&#8226; Mortgage-Related and Other Asset-Backed Securities Risk:</b> Mortgage-related and other asset-backed securities are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the market for the assets underlying such securities. As a result, during periods of declining asset value, difficult or frozen credit markets, swings in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to extension risk, where issuers may pay principal later than expected, and prepayment risk, where issuers may pay principal more quickly than expected, causing proceeds to be reinvested at lower prevailing interest rates.</p><p><b>&#8226; Liquidity Risk: </b>Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations. Investments in non-investment grade debt securities (sometimes called junk bonds) and asset-backed securities have a greater risk of being or becoming less liquid than investments in other, higher-rated debt securities.</p><p><b>&#8226; Leverage Risk: </b>Leverage is investment exposure which exceeds the initial amount invested. Leverage can cause the portfolio to lose more than the principal amount invested. Leverage can magnify the portfolio&#8217;s gains and losses and therefore increase its volatility.</p><p><b> &#8226; Derivatives Risk:</b> Derivatives can be complex instruments, which may experience sudden and unpredictable changes in price or liquidity and may be difficult to value, sell or unwind. The value of derivatives is based on the value of other securities or indexes. They can also create investment exposure that is greater than their cost may suggest (known as <i>leverage risk</i>). Derivative transactions may also involve a counterparty. Such transactions are subject to the credit risk and/or the ability of the counterparty to perform in accordance with the terms of the transaction.</p><p><b>&#8226; Forward Commitments Risk:</b> Fixed income securities may be purchased on a &#8220;forward commitment&#8221; or &#8220;when-issued&#8221; basis (meaning securities are purchased or sold with payment and delivery taking place in the future). In forward commitment or when-issued transactions, if the seller or buyer, as the case may be, fails to consummate the transaction, the counterparty may miss the opportunity of obtaining a price or yield considered to be advantageous.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p><p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p><p><b>&#8226; Value Companies Risk:</b> Value companies are those that are thought to be undervalued and that a company&#8217;s stock is trading for less than its intrinsic value. There is a risk that the determination that a stock is undervalued is not correct or is not recognized in the market.</p><p><b>&#8226; High-Yield or "Junk" Securities Risk:</b> High yield securities are typically issued by companies that are highly leveraged, less creditworthy or financially distressed and are considered to be mostly speculative in nature (high risk), are potentially less liquid, and have a greater risk of loss, that is ,they are more likely to default than higher rated securities.</p><p><b>&#8226; Emerging Markets Risk:</b> Investments in or exposure to investments in emerging markets, such as those in Latin America, Asia, the Middle East, Eastern Europe and Africa, may be riskier than developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, political and economic instability, less governmental regulation of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.</p><p><b>&#8226; Non-Diversification Risk:</b> The portfolio is classified as non-diversified and may invest a greater percentage of its assets in a single issuer or a fewer number of issuers than a diversified portfolio. This increases potential price volatility and the risk that its value could go down because of the poor performance of a single investment or a small number of investments.</p><p><b>&#8226; Inflation-Indexed Debt Securities Risk:</b> The principal values of inflation-indexed debt securities tend to increase when inflation rises and decrease when inflation falls.</p><p><b>&#8226; Growth Companies Risk:</b> Growth companies have the potential for above average or rapid growth but may give the portfolio a higher risk of price volatility than investments in &#8220;undervalued&#8221; companies.</p><p><b>&#8226; Mid-Capitalization Companies Risk:</b> Mid-capitalization companies may be riskier and more susceptible to price swings than larger companies. Mid-capitalization companies may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger, more established companies.</p><p><b>&#8226; Convertible Securities Risk:</b> Convertible securities have <i>credit risk</i> and <i>interest rate risk</i> and may present less risk than investments in a company&#8217;s common stock but more risk than investments in the company&#8217;s senior debt securities.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The portfolio aims to provide diversification across major asset classes &#8211; cash equivalents, fixed income, domestic equity, and international equity &#8211; by investing primarily in Class P shares of other Pacific Select Fund portfolios (each, an "Acquired Fund" or "Underlying Portfolio" or collectively, the "Underlying Portfolios").

There is no guarantee that the portfolio will achieve its investment objective. There may be some losses in the values of the investment as asset values fluctuate. The value of your portfolio shares will fluctuate and you could lose money. The portfolio may be affected by the following principal risks, among other non-principal risks:</p><p><b>&#8226; Asset Allocation Fund of Funds Risk:</b> Typically, the fund of funds are exposed to the same risks as the Underlying Portfolios in direct proportion to the allocation of assets among those portfolios. Allocations among the Underlying Portfolios are determined using an asset allocation process, which seeks to optimize returns by allocating among different asset classes given various levels of risk tolerance. The theory behind asset allocation is that diversification among asset classes can help reduce volatility over the long-term, which assumes that asset classes may not move in tandem and that positive returns in one or more classes will help offset negative returns in other asset classes, although you still may lose money and/or experience volatility, particularly during periods of broad market declines. Market and asset class performance may differ in the future from the historical performance and from the assumptions used to develop the allocations. There&#8217;s a risk that you could achieve better returns by investing in an individual portfolio or portfolios representing a single asset class rather than using asset allocation.</p><p><b>&#8226; Potential Conflicts of Interest Risk:</b> PLFA may be subject to competing interests that have the potential to influence its investment decisions for the portfolio. For example, PLFA may be influenced by its view of the best interests of underlying portfolios, such as a view that an underlying portfolio may benefit from additional assets or could be harmed by redemptions. In addition, PLFA may be influenced by the insurance companies which use the asset allocation portfolios as investment vehicles for their variable life and annuity products in terms of how the asset allocation portfolios are managed and their risk profiles.</p><p><b>Principal risks from holdings in Underlying Portfolios</b></p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio's investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager's principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p><p><b>&#8226; Credit Risk:</b> An issuer or guarantor of a debt instrument might be unable or unwilling to meet its financial obligations.</p><p><b>&#8226; Interest Rate Risk:</b> Values of debt securities fluctuate as interest rates change. Debt securities with longer durations or fixed interest rates tend to be more sensitive to changes in interest rates, making them more volatile than debt securities with shorter durations or floating or adjustable interest rates.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p><p><b>&#8226; U.S. Government Securities Risk:</b> Not all U.S. government securities are backed or guaranteed by the U.S. government. There is risk that the U.S. government will not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law.</p><p><b>&#8226; Forward Commitments Risk:</b> Fixed income securities may be purchased on a "forward commitment" or "when-issued" basis (meaning securities are purchased or sold with payment and delivery taking place in the future). In forward commitment or when-issued transactions, if the seller or buyer, as the case may be, fails to consummate the transaction, the counterparty may miss the opportunity of obtaining a price or yield considered to be advantageous.</p><p><b>&#8226; Mortgage-Related and Other Asset-Backed Securities Risk:</b> Mortgage-related and other asset-backed securities are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the market for the assets underlying such securities. As a result, during periods of declining asset value, difficult or frozen credit markets, swings in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to extension risk, where issuers may pay principal later than expected, and prepayment risk, where issuers may pay principal more quickly than expected, causing proceeds to be reinvested at lower prevailing interest rates.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations. Investments in non-investment grade debt securities (sometimes called junk bonds) and asset-backed securities have a greater risk of being or becoming less liquid than investments in other, higher-rated debt securities.</p><p><b>&#8226; Leverage Risk:</b> Leverage is investment exposure which exceeds the initial amount invested. Leverage can cause the portfolio to lose more than the principal amount invested. Leverage can magnify the portfolio&#8217;s gains and losses and therefore increase its volatility.</p><p><b>&#8226; Derivatives Risk:</b> Derivatives can be complex instruments, which may experience sudden and unpredictable changes in price or liquidity and may be difficult to value, sell or unwind. The value of derivatives is based on the value of other securities or indexes. They can also create investment exposure that is greater than their cost may suggest (known as <i>leverage risk</i>). Derivative transactions may also involve a counterparty. Such transactions are subject to the credit risk and/or the ability of the counterparty to perform in accordance with the terms of the transaction.</p><p><b>&#8226; Value Companies Risk:</b> Value companies are those that are thought to be undervalued and that a company&#8217;s stock is trading for less than its intrinsic value. There is a risk that the determination that a stock is undervalued is not correct or is not recognized in the market.</p><p><b>&#8226; Growth Companies Risk:</b> Growth companies have the potential for above average or rapid growth but may give the portfolio a higher risk of price volatility than investments in "undervalued" companies.</p><p><b>&#8226; Mid-Capitalization Companies Risk:</b> Mid-capitalization companies may be riskier and more susceptible to price swings than larger companies. Mid-capitalization companies may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger, more established companies.</p><p><b>&#8226; Emerging Markets Risk:</b> Investments in or exposure to investments in emerging markets, such as those in Latin America, Asia, the Middle East, Eastern Europe and Africa, may be riskier than developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, political and economic instability, less governmental regulation of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.</p><p><b>&#8226; Geographic Concentration Risk:</b> Concentrating investments in a single country, a limited number of countries, or a particular geographic region makes the portfolio more susceptible to adverse economic, political, social, regulatory and other developments in that country, countries or region.</p><p><b>&#8226; High-Yield or "Junk" Securities Risk:</b> High yield securities are typically issued by companies that are highly leveraged, less creditworthy or financially distressed and are considered to be mostly speculative in nature (high risk), are potentially less liquid, and have a greater risk of loss, that is they are more likely to default than higher rated securities.</p><p><b>&#8226; Inflation-Indexed Debt Securities Risk:</b> The principal values of inflation-indexed debt securities tend to increase when inflation rises and decrease when inflation falls.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

There is no guarantee that the portfolio will achieve its investment objective. There may be some losses in the values of the investment as asset values fluctuate. The value of your portfolio shares will fluctuate and you could lose money. The portfolio may be affected by the following principal risks, among other non-principal risks:</p><p><b>&#8226; Asset Allocation Fund of Funds Risk:</b> Typically, the fund of funds are exposed to the same risks as the Underlying Portfolios in direct proportion to the allocation of assets among those portfolios. Allocations among the Underlying Portfolios are determined using an asset allocation process, which seeks to optimize returns by allocating among different asset classes given various levels of risk tolerance. The theory behind asset allocation is that diversification among asset classes can help reduce volatility over the long-term, which assumes that asset classes may not move in tandem and that positive returns in one or more classes will help offset negative returns in other asset classes, although you still may lose money and/or experience volatility, particularly during periods of broad market declines. Market and asset class performance may differ in the future from the historical performance and from the assumptions used to develop the allocations. There&#8217;s a risk that you could achieve better returns by investing in an individual portfolio or portfolios representing a single asset class rather than using asset allocation.</p><p><b>&#8226; Potential Conflicts of Interest Risk:</b> PLFA may be subject to competing interests that have the potential to influence its investment decisions for the portfolio. For example, PLFA may be influenced by its view of the best interests of underlying portfolios, such as a view that an underlying portfolio may benefit from additional assets or could be harmed byredemptions. In addition, PLFA may be influenced by the insurance companies which use the asset allocation portfolios as investment vehicles for their variable life and annuity products in terms of how the asset allocation portfolios are managed and their risk profiles.</p><p><b>Principal risks from holdings in Underlying Portfolios</b></p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p><p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p><p><b>&#8226; Value Companies Risk:</b> Value companies are those that are thought to be undervalued and that a company&#8217;s stock is trading for less than its intrinsic value. There is a risk that the determination that a stock is undervalued is not correct or is not recognized in the market.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Growth Companies Risk:</b> Growth companies have the potential for above average or rapid growth but may give the portfolio a higher risk of price volatility than investments in &#8220;undervalued&#8221; companies.</p><p><b>&#8226; Credit Risk:</b> An issuer or guarantor of a debt instrument might be unable or unwilling to meet its financial obligations.</p><p><b>&#8226; Interest Rate Risk:</b> Values of debt securities fluctuate as interest rates change. Debt securities with longer durations or fixed interest rates tend to be more sensitive to changes in interest rates, making them more volatile than debt securities with shorter durations or floating or adjustable interest rates.</p><p><b>&#8226; U.S. Government Securities Risk:</b> Not all U.S. government securities are backed or guaranteed by the U.S. government. There is risk that the U.S. government will not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law.</p><p><b>&#8226; Mid-Capitalization Companies Risk:</b> Mid-capitalization companies may be riskier and more susceptible to price swings than larger companies. Mid-capitalization companies may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger, more established companies.</p><p><b>&#8226; Forward Commitments Risk:</b> Fixed income securities may be purchased on a &#8220;forward commitment&#8221; or &#8220;when-issued&#8221; basis (meaning securities are purchased or sold with payment and delivery taking place in the future). In forward commitment or when-issued transactions, if the seller or buyer, as the case may be, fails to consummate the transaction, the counterparty may miss the opportunity of obtaining a price or yield considered to be advantageous.</p><p><b>&#8226; Mortgage-Related and Other Asset-Backed Securities Risk:</b> Mortgage-related and other asset-backed securities are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the market for the assets underlying such securities. As a result, during periods of declining asset value, difficult or frozen credit markets, swings in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to extension risk, where issuers may pay principal later than expected, and prepayment risk, where issuers may pay principal more quickly than expected, causing proceeds to be reinvested at lower prevailing interest rates.</p><p><b> &#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations. Investments in smaller companies have a greater risk of being or becoming less liquid than investments in equity securities with larger market capitalizations. Investments in non-investment grade debt securities (sometimes called junk bonds) and asset-backed securities have a greater risk of being or becoming less liquid than investments in other, higher-rated debt securities.</p><p><b> &#8226; Leverage Risk:</b> Leverage is investment exposure which exceeds the initial amount invested. Leverage can cause the portfolio to lose more than the principal amount invested. Leverage can magnify the portfolio&#8217;s gains and losses and therefore increase its volatility.</p><p><b>&#8226; Derivatives Risk:</b> Derivatives can be complex instruments,which may experience sudden and unpredictable changes in price or liquidity and may be difficult to value, sell or unwind. The value of derivatives is based on the value of other securities or indexes. They can also create investment exposure that is greater than their cost may suggest (known as <i>leverage risk</i>). Derivative transactions may also involve a counterparty. Such transactions are subject to the credit risk and/or the ability of the counterparty to perform in accordance with the terms of the transaction.</p><p><b>&#8226; Geographic Concentration Risk:</b> Concentrating investments in a single country, a limited number of countries, or a particular geographic region makes the portfolio more susceptible to adverse economic, political, social, regulatory and other developments in that country, countries or region.</p><p><b>&#8226; Small-Capitalization Companies Risk:</b> Small-capitalization companies may be riskier and more susceptible to price swings than larger companies. Small-capitalization companies,particularly those in their developmental stages, may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger more established companies.</p><p><b>&#8226; Emerging Markets Risk:</b> Investments in or exposure to investments in emerging markets, such as those in Latin America, Asia, the Middle East, Eastern Europe and Africa,may be riskier than developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, political and economic instability, less governmental regulation of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.</p><p><b>&#8226; High-Yield or &#8220;Junk&#8221; Securities Risk:</b> High yield securities are typically issued by companies that are highly leveraged, less creditworthy or financially distressed and are considered to be mostly speculative in nature (high risk), are potentially less liquid, and have a greater risk of loss, that is they are more likely to default than higher rated securities.</p><p><b>&#8226; Tracking Error Risk:</b> Performance of the portfolio may vary substantially from the performance of the portfolio&#8217;s benchmark index due to imperfect correlation between the portfolio&#8217;s investments and the index.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The portfolio aims to provide diversification across major asset classes &#8211; cash equivalents, fixed income, domestic equity, and international equity &#8211; by investing primarily in Class P shares of other Pacific Select Fund portfolios (each, an &#8220;Acquired Fund&#8221; or &#8220;Underlying Portfolio&#8221; or collectively, the &#8220;Underlying Portfolios&#8221;).

There is no guarantee that the portfolio will achieve its investment objective. There may be some losses in the values of the investment as asset values fluctuate. The value of your portfolio shares will fluctuate and you could lose money. The portfolio may be affected by the following principal risks, among other non-principal risks:</p><p><b>&#8226; Asset Allocation Fund of Funds Risk:</b> Typically, the fund of funds are exposed to the same risks as the Underlying Portfolios in direct proportion to the allocation of assets among those portfolios. Allocations among the Underlying Portfolios are determined using an asset allocation process, which seeks to optimize returns by allocating among different asset classes given various levels of risk tolerance. The theory behind asset allocation is that diversification among asset classes can help reduce volatility over the long-term, which assumes that asset classes may not move in tandem and that positive returns in one or more classes will help offset negative returns in other asset classes, although you still may lose money and/or experience volatility, particularly during periods of broad market declines. Market and asset class performance may differ in the future from the historical performance and from the assumptions used to develop the allocations. There&#8217;s a risk that you could achieve better returns by investing in an individual portfolio or portfolios representing a single asset class rather than using asset allocation.</p><p><b>&#8226; Potential Conflicts of Interest Risk:</b> PLFA may be subject to competing interests that have the potential to influence its investment decisions for the portfolio. For example, PLFA may be influenced by its view of the best interests of underlying portfolios, such as a view that an underlying portfolio may benefit from additional assets or could be harmed by redemptions. In addition, PLFA may be influenced by the insurance companies which use the asset allocation portfolios as investment vehicles for their variable life and annuity products in terms of how the asset allocation portfolios are managed and their risk profiles.</p><p><b>Principal risks from holdings in Underlying Portfolios</b></p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p><p><b>&#8226; Value Companies Risk: </b>Value companies are those that are thought to be undervalued and that a company&#8217;s stock is trading for less than its intrinsic value. There is a risk that the determination that a stock is undervalued is not correct or is not recognized in the market.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b> &#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Growth Companies Risk:</b> Growth companies have the potential for above average or rapid growth but may give the portfolio a higher risk of price volatility than investments in &#8220;undervalued&#8221; companies.</p><p><b> &#8226; Mid-Capitalization Companies Risk:</b> Mid-capitalization companies may be riskier and more susceptible to price swings than larger companies. Mid-capitalization companies may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger, more established companies.</p><p><b>&#8226; Geographic Concentration Risk:</b> Concentrating investments in a single country, a limited number of countries, or a particular geographic region makes the portfolio more susceptible to adverse economic, political, social, regulatory and other developments in that country, countries or region.</p><p><b>&#8226; Small-Capitalization Companies Risk:</b> Small-capitalization companies may be riskier and more susceptible to price swings than larger companies. Small-capitalization companies, particularly those in their developmental stages, may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger more established companies.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations. Investments in smaller companies have a greater risk of being or becoming less liquid than investments in equity securities with larger market capitalizations.</p><p><b> &#8226; Tracking Error Risk:</b> Performance of the portfolio may vary substantially from the performance of the portfolio&#8217;s benchmark index due to imperfect correlation between the portfolio&#8217;s investments and the index.</p><p><b>&#8226; Emerging Markets Risk:</b> Investments in or exposure to investments in emerging markets, such as those in Latin America, Asia, the Middle East, Eastern Europe and Africa, may be riskier than developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, political and economic instability, less governmental regulation of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.</p><p><b>&#8226; Leverage Risk:</b> Leverage is investment exposure which exceeds the initial amount invested. Leverage can cause the portfolio to lose more than the principal amount invested. Leverage can magnify the portfolio&#8217;s gains and losses and therefore increase its volatility.</p><p><b>&#8226; Small Number of Holdings Risk:</b> A portfolio with a small number of holdings may have greater exposure to those holdings which could increase potential price volatility compared to portfolios with a greater number of holdings.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non-principal risks:</p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways.Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b>&#8226; Credit Risk:</b> An issuer or guarantor of a debt instrument might be unable or unwilling to meet its financial obligations.</p><p><b>&#8226; U.S. Government Securities Risk:</b> Not all U.S. government securities are backed or guaranteed by the U.S. government.There is risk that the U.S. government will not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law.</p><p><b>&#8226; Interest Rate Risk:</b> Values of debt securities fluctuate as interest rates change. Debt securities with longer durations or fixed interest rates tend to be more sensitive to changes in interest rates, making them more volatile than debt securities with shorter durations or floating or adjustable interest rates.</p><p><b> &#8226; Mortgage-Related and Other Asset-Backed Securities Risk:</b> Mortgage-related and other asset-backed securities are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the market for the assets underlying such securities. As a result, during periods of declining asset value, difficult or frozen credit markets, swings in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to extension risk, where issuers may pay principal later than expected, and prepayment risk, where issuers may pay principal more quickly than expected, causing proceeds to be reinvested at lower prevailing interest rates.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations.</p><p><b>&#8226; Tracking Error Risk:</b> Performance of the portfolio may vary substantially from the performance of the portfolio&#8217;s benchmark index due to imperfect correlation between the portfolio&#8217;s investments and the index.</p><p><b>&#8226; Forward Commitments Risk:</b> Fixed income securities may be purchased on a &#8220;forward commitment&#8221; or &#8220;when-issued&#8221; basis (meaning securities are purchased or sold with payment and delivery taking place in the future). In forward commitment or when-issued transactions, if the seller or buyer, as the case may be, fails to consummate the transaction, the counterparty may miss the opportunity of obtaining a price or yield considered to be advantageous.</p><p><b>&#8226; Index Sampling Risk:</b> Index sampling risk is the chance that the securities selected for the Fund, in the aggregate, will not provide investment performance matching that of the Fund&#8217;s target index.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non-principal risks:</p> <p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p> <p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer. The volatility of non-investment grade debt securities (including loans) may be greater than for investment grade securities.</p> <p><b>&#8226; Credit Risk:</b> An issuer or guarantor of a debt instrument might be unable or unwilling to meet its financial obligations.</p> <p><b>&#8226; High-Yield or &#8220;Junk&#8221; Securities Risk:</b> High yield securities are typically issued by companies that are highly leveraged, less creditworthy or financially distressed and are considered to be mostly speculative in nature (high risk), are potentially less liquid, and have a greater risk of loss, that is they are more likely to default than higher rated securities.</p> <p><b>&#8226; Interest Rate Risk:</b> Values of debt securities fluctuate as interest rates change. Debt securities with longer durations or fixed interest rates tend to be more sensitive to changes in interest rates, making them more volatile than debt securities with shorter durations or floating or adjustable interest rates.</p> <p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations. Investments in non-investment grade debt securities (sometimes called junk bonds) and asset-backed securities have a greater risk of being or becoming less liquid than investments in other, higher-rated debt securities.</p> <p><b>&#8226; Tracking Error Risk:</b> Performance of the portfolio may vary substantially from the performance of the portfolio&#8217;s benchmark index due to imperfect correlation between the portfolio&#8217;s investments and the index.</p> <p><b>&#8226; Index Sampling Risk:</b> Index sampling risk is the chance that the securities selected for the Fund, in the aggregate, will not provide investment performance matching that of the Fund&#8217;s target index.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broadermeconomic or market events.</p><p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller marketcapitalizations.</p><p><b>&#8226; Growth Companies Risk:</b> Growth companies have the potential for above average or rapid growth but may give the portfolio a higher risk of price volatility than investments in &#8220;undervalued&#8221; companies.</p><p><b>&#8226; Tracking Error Risk:</b> Performance of the portfolio may vary substantially from the performance of the portfolio&#8217;s benchmark index due to imperfect correlation between the portfolio&#8217;s investments and the index.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p> <p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p> <p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p> <p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid-capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p> <p><b>&#8226; Value Companies Risk:</b> Value companies are those that are thought to be undervalued and that a company&#8217;s stock is trading for less than its intrinsic value. There is a risk that the determination that a stock is undervalued is not correct or is not recognized in the market.</p> <p><b>&#8226; Tracking Error Risk:</b> Performance of the portfolio may vary substantially from the performance of the portfolio&#8217;s benchmark index due to imperfect correlation between the portfolio&#8217;s investments and the index.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non-principal risks:</p> <p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p> <p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p> <p>&#8226; Equity Securities Risk: Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p> <p><b>&#8226; Small-Capitalization Companies Risk:</b> Small-capitalization companies may be riskier and more susceptible to price swings than larger companies. Small-capitalization companies, particularly those in their developmental stages, may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger more established companies.</p> <p><b>&#8226; Growth Companies Risk:</b> Growth companies have the potential for above average or rapid growth but may give the portfolio a higher risk of price volatility than investments in &#8220;undervalued&#8221; companies.</p> <p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations. Investments in smaller companies have a greater risk of being or becoming less liquid than investments in equity securities with larger market capitalizations.</p> <p><b>&#8226; Tracking Error Risk:</b> Performance of the portfolio may vary substantially from the performance of the portfolio&#8217;s benchmark index due to imperfect correlation between the portfolio&#8217;s investments and the index.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non-principal risks:</p> <p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p> <p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p> <p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p> <p><b>&#8226; Small-Capitalization Companies Risk:</b> Small-capitalization companies may be riskier and more susceptible to price swings than larger companies. Small-capitalization companies, particularly those in their developmental stages, may have a shorter history of operations, a more limited ability to raise capital, may have inexperienced management and limited product lines, and more speculative prospects for future growth or sustained earnings or market share than larger more established companies.</p> <p><b>&#8226; Value Companies Risk:</b> Value companies are those that are thought to be undervalued and that a company&#8217;s stock is trading for less than its intrinsic value. There is a risk that the determination that a stock is undervalued is not correct or is not recognized in the market.</p> <p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations. Investments in smaller companies have a greater risk of being or becoming less liquid than investments in equity securities with larger market capitalizations.</p> <p><b>&#8226; Tracking Error Risk:</b> Performance of the portfolio may vary substantially from the performance of the portfolio&#8217;s benchmark index due to imperfect correlation between the portfolio&#8217;s investments and the index.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non- principal risks:</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b> Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p><p><b>&#8226; Companies Traded Over-The-Counter Risk:</b> Companies traded over-the-counter (OTC) trade less frequently and in smaller volumes than exchange-listed stocks and may experience greater price volatility than exchange-listed stocks.</p><p><b>&#8226; Large-Capitalization Companies Risk:</b> Large-capitalization companies tend to have more stable prices than small- or mid- capitalization companies, but are still subject to the risks of equity securities. In exchange for this potentially lower risk, the portfolio&#8217;s value may not rise as much as the value of a portfolio that emphasizes companies with smaller market capitalizations.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations.</p><p><b>&#8226; Geographic Concentration Risk:</b> Concentrating investments in a single country, a limited number of countries, or a particular geographic region makes the portfolio more susceptible to adverse economic, political, social, regulatory and other developments in that country, countries or region.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Accordingly, you could lose money. The portfolio may be affected by the following principal risks, among other non- principal risks:</p><p><b>&#8226; Active Management Risk:</b> There is no guarantee that the manager&#8217;s principal investment strategies and techniques, as well as particular investment decisions, will achieve the portfolio&#8217;s investment objective, which could have an adverse impact on the portfolio&#8217;s performance generally, relative to other portfolios with similar investment objectives or relative to its benchmark.</p><p><b>&#8226; Market and Regulatory Risk:</b> Events in the financial markets and in the economy may cause volatility and uncertainty and may affect performance. Events in one market may adversely impact other markets. Future events may impact the portfolio in unforeseen ways. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions may impair portfolio management and have unexpected consequences on particular markets, strategies, or investments.</p><p><b>&#8226; Price Volatility Risk:</b> The market value of the portfolio&#8217;s investments will go up or down, sometimes rapidly or unpredictably, or may fail to rise, as a result of market conditions or for reasons specific to a particular issuer.</p><p><b>&#8226; Equity Securities Risk:</b> Stock markets are volatile. The price of equity securities tend to go up or down in value, sometimes rapidly and unpredictably, in response to many factors, which may be due to the particular issuer, its industry or broader economic or market events.</p><p><b>&#8226; Companies Traded Over-The-Counter Risk:</b> Companies traded over-the-counter (OTC) trade less frequently and in smaller volumes than exchange-listed stocks and may experience greater price volatility than exchange-listed stocks.</p><p><b>&#8226; Foreign Markets Risk:</b> Exposure to foreign markets through issuers can involve additional risks relating to market, economic, political, regulatory, geopolitical, or other conditions. These factors can make foreign investments more volatile and less liquid than U.S. investments. In addition, foreign markets can react differently to these conditions than the U.S. market.</p><p><b>&#8226; Currency Risk:</b> Securities denominated in foreign currencies may be affected by changes in rates of exchange between those currencies and the U.S. dollar. Currency exchange rates may be volatile and may be affected by, among other factors, the general economic conditions of a country, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.</p><p><b>&#8226; Emerging Markets Risk:</b> Investments in or exposure to investments in emerging markets, such as those in Latin America, Asia, the Middle East, Eastern Europe and Africa, may be riskier than developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, political and economic instability, less governmental regulation of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.</p><p><b>&#8226; Liquidity Risk:</b> Liquidity is the ability to sell securities or other investments at about carrying cost within a reasonable amount of time, which relies on the willingness of market participants to buy and sell securities. Certain investments may be difficult to purchase and sell, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. If the portfolio holds illiquid securities, it may be unable to take advantage of market opportunities or it may be forced to sell other, more desirable, liquid securities or sell illiquid securities at a loss if it is required to raise cash to conduct its operations.</p><p><b>&#8226; Geographic Concentration Risk:</b> Concentrating investments in a single country, a limited number of countries, or a particular geographic region makes the portfolio more susceptible to adverse economic, political, social, regulatory and other developments in that country, countries or region.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.
