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 falsefalseFee Waiver or Reimbursement0rr_FeeWaiverOrReimbursementOverAssetstruefalsefalsefalsefalsefalsefalsefalsefalsefalsefalse[1]1truetruetrue-0.0026-0.0026falsefalsefalsetruefalseOthernanafalsefalseFee Waiver or Reimbursement7falseRowprimaryElement*9false0rr_NetExpensesOverAssetsrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00940.0094[4],[7]falsefalsefalsetruefalse2truetruetrue0.01250.0125[2]falsefalsefalsetruefalse3falsetruetrue00falsefalsefalsetruefalse4falsetruetrue00falsefalsefalsetruefalse5falsetruetrue00falsefalsefalsetruefalse6falsetruetrue00falsefalsefalsetruefalse7truetruetrue0.00910.0091[3],[7]falsefalsefalsetruefalse8truetruetrue0.00900.0090[6],[7]falsefalsefalsetruefalse9truetruetrue0.00930.0093[6],[7]falsefalsefalsetruefalse10truetruetrue0.01050.0105[6],[7]falsefalsefalsetruefalse11falsetruetrue00falsefalsefalsetruefalse12truetruetrue0.01020.0102[1],[7]falsefalsefalsetruefalse13falsetruetrue00falsefalsefalsetruefalse14falsetruetrue00falsefalsefalsetruefalse15truetruetrue0.01200.0120[5]falsefalsefalsetruefalse16falsetruetrue00falsefalsefalsetruefalse17truetruetrue0.01750.0175[6],[7]falsefalsefalsetruefalse18truetruetrue0.01040.0104[6],[7]falsefalsefalsetruefalse19falsetruetrue00falsefalsefalsetruefalse20falsetruetrue00falsefalsefalsetruefalseOtherrr: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 falsefalseNet Expenses (as a percentage of Assets)0rr_NetExpensesOverAssetstruefalsefalsefalsefalsefalsefalsefalsefalsefalsefalse[1][2]1truetruetrue0.00940.0094falsefalsefalsetruefalseOthernanafalsefalseNet Expenses (as a percentage of Assets)1The investment manager and administrator have contractually agreed to waive or assume certain expenses so that common expenses of the Fund (excluding Rule 12b-1 fees and acquired fund fees and expenses) do not exceed 0.68% (other than certain non-routine expenses), until April 30, 2012.

A significant to substantial portion of the Fund's investments may be in smaller and mid-size companies.</p><p>In evaluating sector (broad industry) weightings in the Fund's investment portfolio, the investment manager considers, but may deviate from, the relative weightings of sectors in the Russell 3000&#174; Growth Index. Consequently, the Fund, from time to time, may have significant positions in particular sectors such as technology (including electronic technology, technology services, biotechnology and health care technology).</p><p>The investment manager uses fundamental, "bottom-up" research to seek companies meeting its criteria of growth potential, quality and valuation. In seeking sustainable growth characteristics, the investment manager looks for companies that it believes can produce sustainable earnings and cash flow growth, evaluating the long term market opportunity and competitive structure of an industry to target leaders and emerging leaders.

A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.</p><p>Generally, stocks have historically outperformed other types of investments over the long term. Individual stock prices, however, tend to go up and down more dramatically. A slower-growth or recessionary economic environment could have an adverse effect on the price of the various stocks held by the Fund.</p><p>Growth Style Investing</p><p>Growth stock prices reflect projections of future earnings or revenues, and can, therefore, fall dramatically if the company fails to meet those projections. Prices of these companies&#146; securities may be more volatile than other securities, particularly over the short term.</p><p>Smaller and Midsize Companies</p><p>Securities issued by smaller and midsize companies may be more volatile in price than those of larger companies, involve substantial risks and should be considered speculative. Such risks may include greater sensitivity to economic conditions, less certain growth prospects, lack of depth of management and funds for growth and development and limited or less developed product lines and markets. In addition, smaller companies may be particularly affected by interest rate increases, as they may find it more difficult to borrow money to continue or expand operations, or may have difficulty in repaying any loans.</p><p>Focus</p><p>To the extent that the Fund has significant investments in one or a few sectors, such as technology, it bears more risk than a fund which always maintains broad sector diversification. Technology company stocks can be subject to abrupt or erratic price movements and have been volatile due to the rapid pace of product change and development affecting such companies. Technology companies are subject to significant competitive pressures, such as new market entrants, aggressive pricing, and tight profit margins. The biotechnology and health technology industries are affected by government regulatory requirements, regulatory approval for new drugs and medical products, patent considerations, product liability, and similar matters.</p><p>Foreign Securities</p><p>Investing in foreign securities typically involves more risks than investing in U.S. securities, including risks related to currency exchange rates and policies, country or government specific issues, less favorable trading practices or regulation and greater price volatility. Certain of these risks also may apply to securities of U.S. companies with significant foreign operations.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio.

REITs typically concentrate on a specific geographic region or property type. The Fund may also invest in issuers engaged in businesses whose products and services are related to the real estate sector.</p><p>Under normal market conditions, the Fund expects to be invested predominantly in equity securities, primarily common stocks. The Fund is a "non-diversified" fund, which means it generally invests a greater portion of its assets in the securities of one or more issuers and invests overall in a smaller number of issuers than a diversified fund.</p><p>For purposes of pursuing its investment goal, the Fund may enter into currency forwards for hedging purposes to manage currency risks and exposure. The use of these derivative transactions may allow the Fund to obtain net long or net negative (short) exposure to selected currencies.</p><p>The investment manager seeks to limit price volatility by investing across markets and property types and seeks to provide a consistently high level of income. When selecting investments for the Fund&#146;s portfolio, the investment manager applies a &#147;bottom-up" stock selection process that incorporates macro-level views in the evaluation process. The investment manager&#146;s portfolio construction process combines: bottom-up analysis of individual stock and real estate market fundamentals; and top-down macro overlays to provide country/regional, property type, and company size perspectives in identifying international/local cyclical and thematic trends that highlight investment opportunities.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.</p><p>Real Estate Securities</p><p>By concentrating in the real estate industry, the Fund carries much greater risk of adverse developments in the real estate industry than a fund that invests in a wide variety of industries. Real estate values rise and fall in response to a variety of factors, including local, regional and national economic conditions, interest rates, tax and insurance considerations, changes in zoning laws, environmental regulations or hazards, or overbuilding, increases in property taxes and operating expenses or value decline in a neighborhood. When economic growth is slow, demand for property decreases and prices may decline.</p><p>REITs</p><p>A REIT's performance depends on the types, values and locations of the properties it owns and how well those properties are managed. A decline in rental income may occur because of extended vacancies, increased competition from other properties, tenants' failure to pay rent or poor management. Because a REIT may be invested in a limited number of projects or in a particular market segment, it may be more susceptible to adverse developments affecting a single project or market segment than more broadly diversified investments. Loss of status as a qualified REIT under the U.S. federal tax laws could adversely affect the value of a particular REIT or the market for REITs as a whole.</p><p>Foreign Securities</p><p>Investing in foreign securities typically involves more risks than investing in U.S. securities, including risks related to currency exchange rates and policies, country or government specific issues, less favorable trading practices or regulation and greater price volatility. Certain of these risks also may apply to securities of U.S. companies with significant foreign operations.</p><p>Market</p><p>The market value of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.</p><p>Generally, stocks have historically outperformed other types of investments over the long term. Individual stock prices, however, tend to go up and down more dramatically. A slower-growth or recessionary economic environment could have an adverse effect on the price of the various stocks held by the Fund.</p><p>Derivative Instruments</p><p>The performance of derivative instruments depends largely on the performance of an underlying currency, security or index and such derivative instruments often have risks similar to their underlying instrument, in addition to other risks. Derivative instruments involve costs, may be volatile and illiquid, may give rise to leverage and may involve a small initial investment relative to the risk assumed. There may also be imperfect correlation between the value of the derivative and the underlying instrument. When used for hedging, the change in value of the derivative may also not correlate specifically with the currency, security or other risk being hedged. With over-the-counter derivatives, there is the risk that the other party to the transaction will fail to perform.</p><p>Non-Diversification</p><p>Because the Fund is non-diversified, it may be more sensitive to economic, business, political or other changes affecting similar issuers or investments than a diversified fund, which may result in greater fluctuation in the value of the Fund&#146;s shares and greater risk of loss.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The Fund may also invest up to 20% of its net assets in debt securities, including any combination of the following investments: corporate, agency and government bonds issued in the United States and other countries; and notes and debentures (collectively with bonds referred to as debt securities.) The Fund generally invests between 60% and 80% of its net assets in common stocks, and between 20% and 40% of its net assets in a combination of convertible securities and debt securities. The Fund may invest up to 25% of its net assets in foreign securities, including developing or emerging markets.</p><p>While the Fund does not concentrate in any one industry, from time to time, based on economic conditions, it may make significant investments in certain sectors.</p><p>The Fund&#146;s strategy is to invest in a broadly diversified portfolio of equity securities that the Fund&#146;s investment manager considers to be financially strong. The Fund attempts to buy equity securities when they are selling at attractive prices according to measurements such as relative dividend yield, book value, revenues and normalized earnings. The Fund&#146;s investment manager emphasizes dividend yield in selecting stocks for the Fund because the investment manager believes that, over time, dividend income can contribute significantly to total return and is a more consistent source of investment return than capital appreciation.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.</p><p>Market</p><p>The market value of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.</p><p>Generally, stocks have historically outperformed other types of investments over the long term. Individual stock prices, however, tend to go up and down more dramatically. A slower-growth or recessionary economic environment could have an adverse effect on the price of the various stocks held by the Fund.</p><p>Convertible Securities</p><p>Convertible securities are subject to the risks of stocks when the underlying stock price is high relative to the conversion price (because more of the security's value resides in the conversion feature) and debt securities when the underlying stock price is low relative to the conversion price (because the conversion feature is less valuable). A convertible security is not as sensitive to interest rate changes as a similar non-convertible debt security, and generally has less potential for gain or loss than the underlying stock.</p><p>Blend Style Investing</p><p>A &#147;blend&#148; strategy results in investments in both growth and value stocks, or in stocks with characteristics of both. Growth stock prices reflect projections of future earnings or revenues and can fall dramatically if the company fails to meet those projections. With respect to value stocks, if other investors fail to recognize the company&#146;s value, or favor investing in faster-growing companies, value stocks may not increase in value as anticipated by the Fund's investment manager or may decline even further.</p><p>Income</p><p>Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall, when dividend income from investments in stocks decline, or when the Fund experiences defaults on debt securities it holds.</p><p>Focus</p><p>To the extent that the Fund focuses on particular countries, regions, industries, sectors or types of investment from time to time, the Fund may be subject to greater risks of adverse developments in such areas of focus than a fund that invests in a wider variety of countries, regions, industries, sectors or investments.</p><p>Credit</p><p>An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's credit rating may affect a security's value.</p><p>High-Yield Debt Securities</p><p>Issuers of lower-rated or "high yield" debt securities are not as strong financially as those issuing higher credit quality debt securities. These issuers are more likely to encounter financial difficulties and are more vulnerable to changes in the relevant economy, such as a recession or a sustained period of rising interest rates, that could affect their ability to make interest and principal payments when due. The prices of high yield debt securities generally fluctuate more than those of higher credit quality. High yield debt securities are generally more illiquid (harder to sell) and harder to value.</p><p>Foreign Securities</p><p>Investing in foreign securities typically involves more risks than investing in U.S. securities, including risks related to currency exchange rates and policies, country or government specific issues, less favorable trading practices or regulation and greater price volatility. Certain of these risks also may apply to securities of U.S. companies with significant foreign operations. The risks of investing in foreign securities are typically greater in less developed or emerging market countries.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Lower-rated securities generally pay higher yields than more highly rated securities to compensate investors for the higher risk. These securities include bonds, notes, debentures, convertible securities, bank loans and loan participations and senior and subordinated debt securities.</p><p>The Fund may invest up to 100% of its total assets in debt securities that are rated below investment grade, sometimes called "junk bonds." Investment grade debt securities are rated in one of the top four ratings categories by independent rating organizations such as Standard &amp; Poor's (S&amp;P&#174;) and Moody's Investors Service (Moody's). The Fund may buy both rated and unrated debt securities, including securities rated below B by Moody's or S&amp;P (or deemed comparable by the Fund&#146;s investment manager). The Fund may also invest in securities issued by companies and governments in any foreign country, developed or developing. Foreign securities held by the Fund generally will be denominated in U.S. dollars and traded on U.S. markets.</p><p>The Fund may from time to time enter into various derivative transactions, particularly credit default swap agreements, interest rate swap agreements and currency forwards. The use of these derivative transactions may allow the Fund to obtain net long or short exposures to selected credit risks, interest rates, currencies or countries. These derivative transactions may be used to enhance Fund returns, increase liquidity, gain exposure to particular instruments or markets in a more efficient or less expensive way and/or hedge risks associated with its other portfolio investments.</p><p>The Fund's investment manager is a research driven, fundamental investor that relies on a team of analysts to provide in-depth industry expertise and uses both qualitative and quantitative analysis to evaluate issuers. As a "bottom-up" investor, the investment manager focuses primarily on individual securities. The investment manager also considers sectors when choosing investments.</p><p>In selecting securities for the Fund&#146;s investment portfolio, the investment manager does not rely principally on the ratings assigned by rating agencies, but performs its own independent investment analysis to evaluate the creditworthiness of the issuer. The investment manager considers a variety of factors, including the issuer&#146;s experience and managerial strength, its sensitivity to economic conditions, and its current financial condition.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.</p><p>Credit</p><p>An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's credit rating may affect a security's value.</p><p>High-Yield Debt Securities</p><p>Issuers of lower-rated or "high yield" debt securities are not as strong financially as those issuing higher credit quality debt securities. These issuers are more likely to encounter financial difficulties and are more vulnerable to changes in the relevant economy, such as a recession or a sustained period of rising interest rates, that could affect their ability to make interest and principal payments when due. The prices of high yield debt securities generally fluctuate more than those of higher credit quality. High yield debt securities are generally more illiquid (harder to sell) and harder to value.</p><p>Interest Rate</p><p>When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. In general, securities with longer maturities are more sensitive to these interest rate changes.</p><p>Income</p><p>Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.</p><p>Foreign Securities</p><p>Investing in foreign securities typically involves more risks than investing in U.S. securities, including risks related to currency exchange rates and policies, country or government specific issues, less favorable trading practices or regulation and greater price volatility. Certain of these risks also may apply to securities of U.S. companies with significant foreign operations. The risks of investing in foreign securities are typically greater in less developed or emerging market countries.</p><p>Prepayment</p><p>Prepayment risk occurs when a debt security can be repaid in whole or in part prior to the security's maturity and the Fund must reinvest the proceeds it receives, during periods of declining interest rates, in securities that pay a lower rate of interest.</p><p>Derivative Instruments</p><p>The performance of derivative instruments depends largely on the performance of an underlying currency, security or index and such derivative instruments often have risks similar to their underlying instrument, in addition to other risks. Derivative instruments involve costs, may be volatile and illiquid, may give rise to leverage and may involve a small initial investment relative to the risk assumed. There may also be imperfect correlation between the value of the derivative and the underlying instrument. When used for hedging, the change in value of the derivative may also not correlate specifically with the currency, security or other risk being hedged. With over-the-counter derivatives, there is the risk that the other party to the transaction will fail to perform.</p><p>Market</p><p>The market value of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The Fund may shift its investments from one asset class to another based on the investment manager's analysis of the best opportunities for the Fund&#146;s portfolio in a given market. The equity securities in which the Fund invests consist primarily of common stocks. Debt securities include all varieties of fixed, floating and variable rate instruments, including secured and unsecured bonds, bonds convertible into common stock, debentures, and shorter term instruments. The Fund seeks income by selecting investments such as corporate, foreign and U.S. Treasury bonds, as well as stocks with dividend yields the investment manager believes are attractive. The Fund may invest up to 100% of its total assets in debt securities that are rated below investment grade (also known as "junk bonds"), including a portion in defaulted securities. The Fund maintains the flexibility to invest in securities of companies from a variety of sectors, but from time to time, based on economic conditions, the Fund may have significant investments in particular sectors. The Fund may also invest up to 25% of its assets in foreign securities, either directly or through depositary receipts.</p><p>The Fund's investment manager searches for undervalued or out-of-favor securities it believes offer opportunities for income today and significant growth tomorrow. It generally performs independent analysis of the debt securities being considered for the Fund's portfolio, rather than relying principally on the ratings assigned by rating organizations. In analyzing both debt and equity securities, the investment manager considers a variety of factors, including:</p><p>a security's relative value based on such factors as anticipated cash flow, interest or dividend coverage, asset coverage, and earnings prospects;</p><p>the experience and strength of the company's management;</p><p>the company's changing financial condition and market recognition of the change;</p><p>the company's sensitivity to changes in interest rates and business conditions; and</p><p>the company's debt maturity schedules and borrowing requirements.</p><p>When choosing equity investments for the Fund, the investment manager applies a "bottom-up," long-term approach, focusing on the market price of a company's securities relative to the investment manager's evaluation of the company's long-term earnings, asset value and cash flow potential. The investment manager also considers a company's price/earnings ratio, profit margins and liquidation value.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.</p><p>Credit</p><p>An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's credit rating may affect a security's value.</p><p>High-Yield Debt Securities</p><p>Issuers of lower-rated or "high yield" debt securities are not as strong financially as those issuing higher credit quality debt securities. These issuers are more likely to encounter financial difficulties and are more vulnerable to changes in the relevant economy, such as a recession or a sustained period of rising interest rates, that could affect their ability to make interest and principal payments when due. The prices of high yield debt securities generally fluctuate more than those of higher credit quality. High yield debt securities are generally more illiquid (harder to sell) and harder to value.</p><p>Market</p><p>The market value of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.</p><p>Generally, stocks have historically outperformed other types of investments over the long term. Individual stock prices, however, tend to go up and down more dramatically. A slower-growth or recessionary economic environment could have an adverse effect on the price of the various stocks held by the Fund.</p><p>Interest Rate</p><p>When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. In general, securities with longer maturities are more sensitive to these interest rate changes.</p><p>Income</p><p>Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.</p><p>Focus</p><p>To the extent that the Fund focuses on particular countries, regions, industries, sectors or types of investment from time to time, the Fund may be subject to greater risks of adverse developments in such areas of focus than a fund that invests in a wider variety of countries, regions, industries, sectors or investments.</p><p>Foreign Securities</p><p>Investing in foreign securities typically involves more risks than investing in U.S. securities, including risks related to currency exchange rates and policies, country or government specific issues, less favorable trading practices or regulation and greater price volatility. Certain of these risks also may apply to securities of U.S. companies with significant foreign operations.</p><p>Value Style Investing</p><p>A value stock may not increase in price as anticipated by the investment manager if other investors fail to recognize the company's value and bid up the price, the markets favor faster-growing companies, or the factors that the investment manager believes will increase the price of the security do not occur.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.</p><p>Prepayment</p><p>Prepayment risk occurs when a debt security can be repaid in whole or in part prior to the security's maturity and the Fund must reinvest the proceeds it receives, during periods of declining interest rates, in securities that pay a lower rate of interest.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities.

Such risks may include greater sensitivity to economic conditions, less certain growth prospects, lack of depth of management and funds for growth and development and limited or less developed product lines and markets. In addition, smaller companies may be particularly affected by interest rate increases, as they may find it more difficult to borrow money to continue or expand operations, or may have difficulty in repaying any loans.</p><p>Foreign Securities</p><p>Investing in foreign securities typically involves more risks than investing in U.S. securities, including risks related to currency exchange rates and policies, country or government specific issues, less favorable trading practices or regulation and greater price volatility.

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 falsefalseFee Waiver or Reimbursement0rr_FeeWaiverOrReimbursementOverAssetstruefalsefalsefalsefalsefalsefalsefalsefalsefalsefalse[1]1truetruetrue-0.0051-0.0051falsefalsefalsetruefalseOthernanafalsefalseFee Waiver or Reimbursement7falseRowprimaryElement*9false0rr_NetExpensesOverAssetsrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1truetruetrue0.00940.0094[4],[7]falsefalsefalsetruefalse2truetruetrue0.01250.0125[2]falsefalsefalsetruefalse3falsetruetrue00falsefalsefalsetruefalse4falsetruetrue00falsefalsefalsetruefalse5falsetruetrue00falsefalsefalsetruefalse6falsetruetrue00falsefalsefalsetruefalse7truetruetrue0.00910.0091[3],[7]falsefalsefalsetruefalse8truetruetrue0.00900.0090[6],[7]falsefalsefalsetruefalse9truetruetrue0.00930.0093[6],[7]falsefalsefalsetruefalse10truetruetrue0.01050.0105[6],[7]falsefalsefalsetruefalse11falsetruetrue00falsefalsefalsetruefalse12truetruetrue0.01020.0102[1],[7]falsefalsefalsetruefalse13falsetruetrue00falsefalsefalsetruefalse14falsetruetrue00falsefalsefalsetruefalse15truetruetrue0.01200.0120[5]falsefalsefalsetruefalse16falsetruetrue00falsefalsefalsetruefalse17truetruetrue0.01750.0175[6],[7]falsefalsefalsetruefalse18truetruetrue0.01040.0104[6],[7]falsefalsefalsetruefalse19falsetruetrue00falsefalsefalsetruefalse20falsetruetrue00falsefalsefalsetruefalseOtherrr: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 falsefalseNet Expenses (as a percentage of Assets)0rr_NetExpensesOverAssetstruefalsefalsefalsefalsefalsefalsefalsefalsefalsefalse[1][2]1truetruetrue0.00910.0091falsefalsefalsetruefalseOthernanafalsefalseNet Expenses (as a percentage of Assets)1The investment manager and administrator have contractually agreed to waive or assume certain expenses so that common expenses of the Fund (excluding Rule 12b-1 fees and acquired fund fees and expenses) do not exceed 0.65% (other than certain non-routine expenses), until April 30, 2012.

The Fund invests primarily in common stocks. A stock price is undervalued, or is a &#147;value,&#148; when it trades at less than the price at which the investment manager believes it would trade if the market reflected all factors relating to the company&#146;s worth. Following this strategy, the Fund invests in companies that the investment manager believes have, for example: stock prices that are low relative to current, or historical or future earnings, book value, cash flow or sales; recent sharp price declines but the potential for good long-term earnings prospects; and valuable intangibles not reflected in the stock price.</p><p>The types of companies the Fund may invest in include those that may be considered out of favor, such as companies attempting to recover from bankruptcy, business setbacks or adverse events (turnarounds) or cyclical downturns, or that may be considered potential takeover targets.</p><p>The Fund may invest up to 25% of its total assets in foreign securities.</p><p>The Fund, from time to time, may have significant investments in particular sectors such as financial services and energy.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.</p><p>Market</p><p>The market value of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.</p><p>Generally, stocks have historically outperformed other types of investments over the long term. Individual stock prices, however, tend to go up and down more dramatically. A slower-growth or recessionary economic environment could have an adverse effect on the price of the various stocks held by the Fund.</p><p>Value Style Investing</p><p>A value stock may not increase in price as anticipated by the investment manager if other investors fail to recognize the company's value and bid up the price, the markets favor faster-growing companies, or the factors that the investment manager believes will increase the price of the security do not occur.</p><p>Companies that may be considered out of favor, particularly companies emerging from bankruptcy, may tend to lose value more quickly in periods of anticipated economic downturns, may have difficulty retaining customers and suppliers and, during economic downturns, may have difficulty paying their debt obligations or finding additional financing.</p><p>Smaller Companies</p><p>Securities issued by smaller companies may be more volatile in price than those of larger companies, involve substantial risks and should be considered speculative. Such risks may include greater sensitivity to economic conditions, less certain growth prospects, lack of depth of management and funds for growth and development and limited or less developed product lines and markets. In addition, smaller companies may be particularly affected by interest rate increases, as they may find it more difficult to borrow money to continue or expand operations, or may have difficulty in repaying any loans.</p><p>Focus</p><p>To the extent that the Fund focuses on particular countries, regions, industries, sectors or types of investment from time to time, the Fund may be subject to greater risks of adverse developments in such areas of focus than a fund that invests in a wider variety of countries, regions, industries, sectors or investments.</p><p>Foreign Securities</p><p>Investing in foreign securities typically involves more risks than investing in U.S. securities, including risks related to currency exchange rates and policies, country or government specific issues, less favorable trading practices or regulation and greater price volatility. Certain of these risks also may apply to securities of U.S. companies with significant foreign operations.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.</p><p>Market</p><p>The market value of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.</p><p>Generally, stocks have historically outperformed other types of investments over the long term. Individual stock prices, however, tend to go up and down more dramatically. A slower-growth or recessionary economic environment could have an adverse effect on the price of the various stocks held by the Fund.</p><p>Smaller and Midsize Companies</p><p>Securities issued by smaller and midsize companies may be more volatile in price than those of larger companies, involve substantial risks and should be considered speculative. Such risks may include greater sensitivity to economic conditions, less certain growth prospects, lack of depth of management and funds for growth and development and limited or less developed product lines and markets. In addition, smaller companies may be particularly affected by interest rate increases, as they may find it more difficult to borrow money to continue or expand operations, or may have difficulty in repaying any loans.</p><p>Focus</p><p>To the extent that the Fund has significant investments in one or a few sectors, such as technology, it bears more risk than a fund which always maintains broad sector diversification. Technology company stocks can be subject to abrupt or erratic price movements and have been volatile due to the rapid pace of product change and development affecting such companies. Technology companies are subject to significant competitive pressures, such as new market entrants, aggressive pricing, and tight profit margins. The biotechnology and health technology industries are affected by government regulatory requirements, regulatory approval for new drugs and medical products, patent considerations, product liability, and similar matters.</p><p>Growth Style Investing</p><p>Growth stock prices reflect projections of future earnings or revenues, and can, therefore, fall dramatically if the company fails to meet those projections. Prices of these companies&#146; securities may be more volatile than other securities, particularly over the short term.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Debt securities include all varieties of fixed and floating rate income securities, including bonds, loans, bank loans (and loan participations), mortgage securities and other asset-backed securities, convertible securities and municipal securities, including Build America Bonds. The Fund shifts its investments among various classes of debt securities and at any given time may have a considerable amount of its assets invested in any one class.</p><p>The Fund may invest up to 100% of its assets in high yield, lower-quality debt securities (also known as "junk bonds"). The below-investment grade debt securities in which the Fund invests are generally rated at least Caa by Moody's or CCC by S&amp;P&#174; or are unrated securities the Fund's investment manager determines are of comparable quality.</p><p>The Fund may also invest in many different securities issued or guaranteed by the U.S. government or by non-U.S. governments or their respective agencies or instrumentalities, including mortgage securities.</p><p>For purposes of pursuing its investment goals, the Fund may enter into various currency related transactions involving derivative instruments, including currency and cross currency forwards and currency and currency index futures contracts. The use of these derivative transactions may allow the Fund to obtain net long or net negative (short) exposure to selected currencies. The Fund may also enter into interest rate and credit related transactions involving derivative instruments, including interest rate and credit default swaps, bond/interest rate futures contracts and options thereon. The use of these derivative transactions may allow the Fund to obtain net long or net short exposures to selected interest rates, durations or credit risks. These derivative instruments may also be used for hedging purposes, to enhance Fund returns or to obtain exposure to various market sectors.</p><p>The investment manager uses a "top-down" analysis of macroeconomic trends combined with a "bottom-up" fundamental analysis of market sectors, industries, and issuers to try to take advantage of varying sector reactions to economic events. The investment manager will evaluate country risk, business cycles, yield curves, and values between and within markets.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.</p><p>Credit</p><p>An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's credit rating may affect a security's value. While securities issued by Ginnie Mae are backed by the full faith and credit of the U.S. government, not all securities of the various U.S. government agencies are, including those of Fannie Mae and Freddie Mac. Also guarantees of principal and interest do not apply to market prices, yields or the Fund&#146;s share price. While the U.S. government has recently provided financial support to Fannie Mae and Freddie Mac, no assurance can be given that the U.S. government will always do so, since the U.S. government is not so obligated by law.</p><p>Interest Rate</p><p>When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. In general, securities with longer maturities are more sensitive to these interest rate changes.</p><p>Variable Rate Securities</p><p>Because changes in interest rates on variable rate securities (including floating rate securities) may lag behind changes in market rates, the value of such securities may decline during periods of rising interest rates until their interest rates reset to market rates. If the changes in market rates are substantial, the interest rate on a variable rate security may not rest during a single adjustment period. Lifetime limits on resets may also prevent their rates from adjusting to market rates.</p><p>High-Yield Debt Securities</p><p>Issuers of lower-rated or "high yield" debt securities are not as strong financially as those issuing higher credit quality debt securities. These issuers are more likely to encounter financial difficulties and are more vulnerable to changes in the relevant economy, such as a recession or a sustained period of rising interest rates, that could affect their ability to make interest and principal payments when due. The prices of high yield debt securities generally fluctuate more than those of higher credit quality. High yield debt securities are generally more illiquid (harder to sell) and harder to value.</p><p>Income</p><p>Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.</p><p>Foreign Securities</p><p>Investing in foreign securities typically involves more risks than investing in U.S. securities, and includes risks associated with: political and economic developments - the political, economic and social structures of some foreign countries may be less stable and more volatile than those in the U.S.; trading practices - government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S.; availability of information - foreign issuers may not be subject to the same disclosure, accounting and financial reporting standards and practices as U.S. issuers; limited markets - the securities of certain foreign issuers may be less liquid (harder to sell) and more volatile; and currency exchange rate fluctuations and policies. The risks of foreign investments typically are greater in less developed countries or emerging market countries.</p><p>Prepayment</p><p>Prepayment risk occurs when a debt security can be repaid in whole or in part prior to the security's maturity and the Fund must reinvest the proceeds it receives, during periods of declining interest rates, in securities that pay a lower rate of interest.</p><p><b>Extension Risk</b></p><p>Some debt securities, particularly mortgage securities, are subject to the risk that the debt security&#146;s effective maturity is extended because calls or prepayments are less or slower than anticipated, particularly when interest rates rise. The market value of such security may then decline and become more interest rate sensitive.</p><p>Mortgage Securities</p><p>Mortgage securities differ from conventional debt securities because principal is paid back periodically over the life of the security rather than at maturity. The Fund may receive unscheduled prepayments of principal due to voluntary prepayments, refinancings or foreclosures on the underlying mortgage loans. Because of repayments, mortgage securities may be less effective than some other types of debt securities as a means of "locking in" long-term interest rates and may have less potential for capital appreciation during periods of falling interest rates. A reduction in the anticipated rate of principal prepayments, especially during periods of rising interest rates, may increase or extend the effective maturity of mortgage securities, making them more sensitive to interest rate changes, subject to greater price volatility, and more susceptible than some other debt securities to a decline in market value when interest rates rise.</p><p>Derivative Instruments</p><p>The performance of derivative instruments depends largely on the performance of an underlying currency, security or index and such derivative instruments often have risks similar to their underlying instrument, in addition to other risks. Derivative instruments involve costs, may be volatile and illiquid, may give rise to leverage and may involve a small initial investment relative to the risk assumed. There may also be imperfect correlation between the value of the derivative and the underlying instrument. When used for hedging, the change in value of the derivative may also not correlate specifically with the currency, security or other risk being hedged. With over-the-counter derivatives, there is the risk that the other party to the transaction will fail to perform.</p><p>Market</p><p>The market value of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The Fund makes equal allocations to each of the underlying funds on a fixed percentage basis. The administrator rebalances the Fund&#146;s investments in the underlying funds periodically and may recommend to the Fund&#146;s board of trustees additional or different underlying funds for investment (without the approval of shareholders). These underlying funds, in turn, invest primarily in U.S. and foreign equity securities, and, to a lesser extent, fixed income and money market securities, each following a value oriented approach.</p><p><b>Franklin Income Securities Fund</b><br/>The fund seeks to maximize income while maintaining prospects for capital appreciation by investing, under normal market conditions, in debt and equity securities. The fund may shift its investments from one asset class to another based on the investment manager's analysis of the best opportunities in a given market. The fund seeks income by investing in corporate, foreign and U.S. Treasury bonds, as well as stocks with dividend yields the investment manager believes are attractive. In its search for growth opportunities, the fund maintains the flexibility to invest in common stocks of companies from a variety of industries and may from time to time have significant investments in particular sectors. The fund may invest up to 100% of its assets in debt securities that are rated below investment grade (sometimes called "junk bonds"). The fund may also invest up to 25% of its assets in foreign securities.</p><p><b>Mutual Shares Securities Fund </b><br/>The fund's principal investment goal is capital appreciation and its secondary goal is income. Under normal market conditions, the fund invests primarily in equity securities (including securities convertible into, or that the investment manager expects to be exchanged for, common or preferred stock) of U.S. and foreign companies that the investment manager believes are available at market prices less than their value based on certain recognized or objective criteria (intrinsic value). Under normal market conditions, the fund invests primarily in undervalued securities and, to a lesser extent, in merger arbitrage securities and distressed companies. The fund generally invests the equity portion of its portfolio primarily to predominantly in companies with market capitalization values greater than $5 billion, with a portion or significant amount of its assets in smaller companies. The fund expects to invest significantly in foreign investments. The fund may also use certain derivative instruments to hedge against currency or market risks.</p><p><b>Templeton Growth Securities Fund </b><br/>The fund seeks long-term capital growth. Under normal market conditions, the fund invests primarily to predominantly in the equity securities and depositary receipts of companies located anywhere in the world, including those in the U.S. and emerging markets. It may from time to time have significant investments in particular countries or in particular sectors, such as the financial sector. The fund may invest a portion of its net assets in debt securities of companies and governments located anywhere in the world.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.</p><p>Investing in Underlying Funds</p><p>Because the Fund&#146;s investments are concentrated in the underlying funds, and the Fund&#146;s performance is directly related to the performance of the underlying funds held by it, the ability of the Fund to achieve its investment goal is directly related to the ability of the underlying funds to meet their investment goal. In addition, shareholders of the Fund will indirectly bear the fees and expenses of the underlying funds. The risks described below are the principal risks of the Fund and the underlying funds. For purposes of the discussion below, &#147;Fund&#148; means the Fund and/or one or more of the underlying funds in which the Fund invests.</p><p>Asset Allocation</p><p>The Fund&#146;s ability to achieve its investment goal depends upon the Fund&#146;s asset allocation and underlying funds, which may not achieve the Fund&#146;s goal in view of actual market trends.</p><p>Market</p><p>The market value of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.</p><p>Generally, stocks have historically outperformed other types of investments over the long term. Individual stock prices, however, tend to go up and down more dramatically. A slower-growth or recessionary economic environment could have an adverse effect on the price of the various stocks held by the Fund.</p><p>Value Style Investing</p><p>A value stock may not increase in price as anticipated by the investment manager if other investors fail to recognize the company's value and bid up the price, the markets favor faster-growing companies, or the factors that the investment manager believes will increase the price of the security do not occur.</p><p>Foreign Securities</p><p>Investing in foreign securities typically involves more risks than investing in U.S. securities, and includes risks associated with: political and economic developments - the political, economic and social structures of some foreign countries may be less stable and more volatile than those in the U.S.; trading practices - government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S.; availability of information - foreign issuers may not be subject to the same disclosure, accounting and financial reporting standards and practices as U.S. issuers; limited markets - the securities of certain foreign issuers may be less liquid (harder to sell) and more volatile; and currency exchange rate fluctuations and policies. The risks of foreign investments typically are greater in less developed countries or emerging market countries.</p><p>Focus</p><p>To the extent that the Fund focuses on particular countries, regions, industries, sectors or types of investment from time to time, the Fund may be subject to greater risks of adverse developments in such areas of focus than a fund that invests in a wider variety of countries, regions, industries, sectors or investments.</p><p>Smaller and Midsize Companies</p><p>Securities issued by smaller and midsize companies may be more volatile in price than those of larger companies, involve substantial risks and should be considered speculative. Such risks may include greater sensitivity to economic conditions, less certain growth prospects, lack of depth of management and funds for growth and development and limited or less developed product lines and markets. In addition, smaller companies may be particularly affected by interest rate increases, as they may find it more difficult to borrow money to continue or expand operations, or may have difficulty in repaying any loans.</p><p>Derivative Instruments</p><p>The performance of derivative instruments depends largely on the performance of an underlying currency, security or index and such derivative instruments often have risks similar to their underlying instrument, in addition to other risks. Derivative instruments involve costs, may be volatile and illiquid, may give rise to leverage and may involve a small initial investment relative to the risk assumed. There may also be imperfect correlation between the value of the derivative and the underlying instrument. When used for hedging, the change in value of the derivative may also not correlate specifically with the currency, security or other risk being hedged. With over-the-counter derivatives, there is the risk that the other party to the transaction will fail to perform.</p><p>Income</p><p>Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.</p><p>Credit</p><p>An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's credit rating may affect a security's value.</p><p>Interest Rate</p><p>When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. In general, securities with longer maturities are more sensitive to these interest rate changes.</p><p>High-Yield Debt Securities</p><p>Issuers of lower-rated or "high yield" debt securities are not as strong financially as those issuing higher credit quality debt securities. These issuers are more likely to encounter financial difficulties and are more vulnerable to changes in the relevant economy, such as a recession or a sustained period of rising interest rates, that could affect their ability to make interest and principal payments when due. The prices of high yield debt securities generally fluctuate more than those of higher credit quality. High yield debt securities are generally more illiquid (harder to sell) and harder to value.</p><p>Management</p><p>The underlying funds are subject to management risk because they are each an actively managed investment portfolio. Each underlying funds' investment manager will apply investment techniques and risk analyses in making investment decisions for the underlying fund, but there can be no guarantee that these decisions will produce the desired results.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The Fund invests primarily in fixed income and variable rate mortgage-backed securities, a significant to substantial amount of which is in securities issued by the Government National Mortgage Association (Ginnie Maes). Ginnie Maes represent an ownership interest in mortgage loans pooled together for sale to investors to finance purchases of homes. The mortgage loans may have either fixed or adjustable interest rates. As the underlying mortgage loans are paid off, Ginnie Maes provide investors with monthly payments of interest and principal as well as any unscheduled prepayments on the underlying mortgage loans.</p><p>Ginnie Maes carry a guarantee as to the timely repayment of principal and interest that is backed by the full faith and credit of the U.S. government. The full faith and credit guarantee does not apply to the market prices and yields of the Ginnie Maes or to the net asset value or performance of the Fund, which will vary with changes in interest rates and other market conditions.</p><p>The Fund may also invest in mortgage-backed and other securities issued or guaranteed by the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac). Securities issued or guaranteed by Fannie Mae and Freddie Mac are not backed by the full faith and credit of the U.S. government, but rather are generally supported only by the creditworthiness of the issuer.</p><p>The Fund may invest in U.S. Treasury STRIPS, bills, bonds and notes.</p><p>Government agency or instrumentality issues have different levels of credit support. Ginnie Mae pass-through mortgage certificates are backed by the full faith and credit of the U.S. government. <b>U.S. government-sponsored entities, such as Fannie Mae and Freddie Mac, may be chartered by Acts of Congress, but their securities are neither issued nor guaranteed by the U.S. government. Although the U.S. government has recently provided financial support to Fannie Mae and Freddie Mac, no assurance can be given that the U.S. government will always do so.</b> Investors should remember that guarantees of timely prepayment of principal and interest do not apply to the market prices and yields of the securities or to the net asset value or performance of the Fund, which will vary with changes in interest rates and other market conditions.</p><p>The Fund may also invest in other U.S. government securities, which may or may not be backed by the full faith and credit of the U.S. government.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

The Fund may receive unscheduled prepayments of principal due to voluntary prepayments, refinancings or foreclosures on the underlying mortgage loans. Because of repayments, mortgage securities may be less effective than some other types of debt securities as a means of "locking in" long-term interest rates and may have less potential for capital appreciation during periods of falling interest rates. A reduction in the anticipated rate of principal prepayments, especially during periods of rising interest rates, may increase or extend the effective maturity of mortgage securities, making them more sensitive to interest rate changes, subject to greater price volatility, and more susceptible than some other debt securities to a decline in market value when interest rates rise.</p><p>Interest Rate</p><p>When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. In general, securities with longer maturities are more sensitive to these interest rate changes.</p><p>Prepayment</p><p>Prepayment risk occurs when a debt security can be repaid in whole or in part prior to the security's maturity and the Fund must reinvest the proceeds it receives, during periods of declining interest rates, in securities that pay a lower rate of interest.</p><p>Credit</p><p>An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's credit rating may affect a security's value. While securities issued by Ginnie Mae are backed by the full faith and credit of the U.S. government, not all securities of the various U.S. government agencies are, including those of Fannie Mae and Freddie Mac. Also guarantees of principal and interest do not apply to market prices, yields or the Fund&#146;s share price. While the U.S. government has recently provided financial support to Fannie Mae and Freddie Mac, no assurance can be given that the U.S. government will always do so, since the U.S. government is not so obligated by law.</p><p>Income</p><p>Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.</p><p>Market</p><p>The market value of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities.

Following this value-oriented strategy, the Fund invests primarily in undervalued securities (securities trading at a discount to intrinsic value). The equity securities in which the Fund invests are primarily common stock. To a lesser extent, the Fund also invests in merger arbitrage securities and distressed companies.</p><p>The Fund is not limited to pre-set maximums or minimums governing the size of the companies in which it may invest. However, the Fund currently invests the equity portion of its portfolio primarily to predominantly in mid- and large-cap companies, with the remaining portion of its equity portfolio in smaller companies.</p><p>The Fund expects to invest substantially and may invest up to 100% of its assets in foreign securities, which may include sovereign debt and participations in foreign government debt. The Fund presently does not intend to invest more than a portion (no more than 25%) of its assets in securities of issuers located in emerging market countries.</p><p>The Fund may attempt, from time to time, to hedge (protect) against currency risks, largely using forward foreign currency exchange contracts and currency futures contracts (including currency index futures contracts) when, in the investment manager&#146;s opinion, it would be advantageous to the Fund to do so. The Fund may also, from time to time, attempt to hedge against market risk using a variety of derivatives.</p><p>Portfolio Selection</p><p>The manager employs a research driven, fundamental value strategy for the Fund. Investments are generally selected based on the manager's own analysis of the security's intrinsic value, including for equity securities, an analysis of book value, cash flow potential, long-term earnings and multiples of earnings. The manager examines each investment separately and there are no set criteria as to specific value parameters, asset size, earnings or industry type.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.</p><p>Market</p><p>The market value of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.</p><p>Generally, stocks have historically outperformed other types of investments over the long term. Individual stock prices, however, tend to go up and down more dramatically. A slower-growth or recessionary economic environment could have an adverse effect on the price of the various stocks held by the Fund.</p><p>Value Style Investing</p><p>A value stock may not increase in price as anticipated by the investment manager if other investors fail to recognize the company's value and bid up the price, the markets favor faster-growing companies, or the factors that the investment manager believes will increase the price of the security do not occur.</p><p>Foreign Securities</p><p>Investing in foreign securities typically involves more risks than investing in U.S. securities, and includes risks associated with: political and economic developments - the political, economic and social structures of some foreign countries may be less stable and more volatile than those in the U.S.; trading practices - government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S.; availability of information - foreign issuers may not be subject to the same disclosure, accounting and financial reporting standards and practices as U.S. issuers; limited markets - the securities of certain foreign issuers may be less liquid (harder to sell) and more volatile; and currency exchange rate fluctuations and policies. The risks of foreign investments typically are greater in less developed countries or emerging market countries.</p><p>Merger Arbitrage Securities and Distressed Companies</p><p>A merger or other restructuring, or a tender or exchange offer, proposed or pending at the time the Fund invests in merger arbitrage securities may not be completed on the terms or within the time frame contemplated, resulting in losses to the Fund. Debt obligations of distressed companies typically are unrated, lower-rated, in default or close to default and are generally more likely to become worthless than the securities of more financially stable companies.</p><p>Smaller and Midsize Companies</p><p>Securities issued by smaller and midsize companies may be more volatile in price than those of larger companies, involve substantial risks and should be considered speculative. Such risks may include greater sensitivity to economic conditions, less certain growth prospects, lack of depth of management and funds for growth and development and limited or less developed product lines and markets. In addition, smaller companies may be particularly affected by interest rate increases, as they may find it more difficult to borrow money to continue or expand operations, or may have difficulty in repaying any loans.</p><p>Derivative Instruments</p><p>The performance of derivative instruments depends largely on the performance of an underlying currency, security or index and such derivative instruments often have risks similar to their underlying instrument, in addition to other risks. Derivative instruments involve costs, may be volatile and illiquid, may give rise to leverage and may involve a small initial investment relative to the risk assumed. There may also be imperfect correlation between the value of the derivative and the underlying instrument. When used for hedging, the change in value of the derivative may also not correlate specifically with the currency, security or other risk being hedged. With over-the-counter derivatives, there is the risk that the other party to the transaction will fail to perform.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The investment manager focuses the Fund&#146;s investments on securities believed to be available at market prices less than their value based on certain recognized or objective criteria (intrinsic value). Following this value-oriented strategy, the Fund invests primarily in undervalued securities (securities trading at a discount to intrinsic value). The equity securities in which the Fund primarily invests are common stocks. To a lesser extent, the Fund also invests in merger arbitrage securities and distressed companies.</p><p>The Fund invests primarily in securities of Asian and European companies that the investment manager believes are undervalued.</p><p>The Fund is not limited to pre-set maximums or minimums governing the size of the companies in which it may invest. However, the Fund currently invests the equity portion of its portfolio primarily to predominantly in mid- and large cap companies, with the remaining portion of its equity portfolio in smaller companies.</p><p>The Fund normally invests in securities from at least five different countries, although, from time to time, it may invest all of its assets in a single country. The Fund also may invest up to 20% of its total assets in securities of U.S. issuers, and securities of issuers from the Middle East and the remaining regions of the world, including emerging markets.</p><p>The Fund may attempt, from time to time, to hedge (protect) against currency risks, largely using forward foreign currency exchange contracts and currency futures contracts (including currency index futures contracts) when, in the investment manager&#146;s opinion, it would be advantageous to the Fund to do so. The Fund may also, from time to time, attempt to hedge against market risk using a variety of derivatives.</p><p>Portfolio Selection</p><p>The manager employs a research driven, fundamental value strategy for the Fund. Investments are generally selected based on the manager's own analysis of the security's intrinsic value, including for equity securities, an analysis of book value, cash flow potential, long-term earnings and multiples of earnings. The manager examines each investment separately and there are no set criteria as to specific value parameters, asset size, earnings or industry type.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.</p><p>Generally, stocks have historically outperformed other types of investments over the long term. Individual stock prices, however, tend to go up and down more dramatically. A slower-growth or recessionary economic environment could have an adverse effect on the price of the various stocks held by the Fund.</p><p>Value Style Investing</p><p>A value stock may not increase in price as anticipated by the investment manager if other investors fail to recognize the company's value and bid up the price, the markets favor faster-growing companies, or the factors that the investment manager believes will increase the price of the security do not occur.</p><p>Foreign Securities</p><p>Investing in foreign securities typically involves more risks than investing in U.S. securities, and includes risks associated with: political and economic developments - the political, economic and social structures of some foreign countries may be less stable and more volatile than those in the U.S.; trading practices - government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S.; availability of information - foreign issuers may not be subject to the same disclosure, accounting and financial reporting standards and practices as U.S. issuers; limited markets - the securities of certain foreign issuers may be less liquid (harder to sell) and more volatile; and currency exchange rate fluctuations and policies. The risks of foreign investments typically are greater in less developed countries or emerging market countries.</p><p>Country Focus</p><p>Because the Fund invests its assets primarily in companies in a specific country or region, the Fund is subject to greater risks of adverse developments in that country and/or the surrounding regions than a fund that is more broadly diversified geographically. Political, social or economic disruptions in the country or region, even in countries in which the Fund is not invested, may adversely affect security values in the country or region in which the Fund is invested.</p><p>Merger Arbitrage Securities and Distressed Companies</p><p>A merger or other restructuring, or a tender or exchange offer, proposed or pending at the time the Fund invests in merger arbitrage securities may not be completed on the terms or within the time frame contemplated, resulting in losses to the Fund. Debt obligations of distressed companies typically are unrated, lower-rated, in default or close to default and are generally more likely to become worthless than the securities of more financially stable companies.</p><p>Smaller and Midsize Companies</p><p>Securities issued by smaller and midsize companies may be more volatile in price than those of larger companies, involve substantial risks and should be considered speculative. Such risks may include greater sensitivity to economic conditions, less certain growth prospects, lack of depth of management and funds for growth and development and limited or less developed product lines and markets. In addition, smaller companies may be particularly affected by interest rate increases, as they may find it more difficult to borrow money to continue or expand operations, or may have difficulty in repaying any loans.</p><p>Derivative Instruments</p><p>The performance of derivative instruments depends largely on the performance of an underlying currency, security or index and such derivative instruments often have risks similar to their underlying instrument, in addition to other risks. Derivative instruments involve costs, may be volatile and illiquid, may give rise to leverage and may involve a small initial investment relative to the risk assumed. There may also be imperfect correlation between the value of the derivative and the underlying instrument. When used for hedging, the change in value of the derivative may also not correlate specifically with the currency, security or other risk being hedged. With over-the-counter derivatives, there is the risk that the other party to the transaction will fail to perform.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Following this value-oriented strategy, the Fund invests primarily in undervalued securities (securities trading at a discount to intrinsic value). The equity securities in which the Fund invests are primarily common stock. To a lesser extent, the Fund also invests in merger arbitrage securities and distressed companies.</p><p>The Fund expects to invest a significant portion of its assets in foreign securities, which may include sovereign debt and participations in foreign government debt.</p><p>The Fund is not limited to pre-set maximums or minimums governing the size of the companies in which it may invest. However, the Fund currently invests the equity portion of its portfolio primarily to predominantly in companies with market capitalizations greater than $5 billion, with a portion or significant amount in smaller companies.</p><p>The Fund may attempt, from time to time, to hedge (protect) against currency risks, largely using forward foreign currency exchange contracts and currency futures contracts (including currency index futures contracts) when, in the investment manager&#146;s opinion, it would be advantageous to the Fund to do so. The Fund may also, from time to time, attempt to hedge against market risk using a variety of derivatives.</p><p>Portfolio Selection</p><p>The manager employs a research driven, fundamental value strategy for the Fund. Investments are generally selected based on the manager's own analysis of the security's intrinsic value, including for equity securities, an analysis of book value, cash flow potential, long-term earnings and multiples of earnings. The manager examines each investment separately and there are no set criteria as to specific value parameters, asset size, earnings or industry type.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.</p><p>Market</p><p>The market value of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.</p><p>Generally, stocks have historically outperformed other types of investments over the long term. Individual stock prices, however, tend to go up and down more dramatically. A slower-growth or recessionary economic environment could have an adverse effect on the price of the various stocks held by the Fund.</p><p>Value Style Investing</p><p>A value stock may not increase in price as anticipated by the investment manager if other investors fail to recognize the company's value and bid up the price, the markets favor faster-growing companies, or the factors that the investment manager believes will increase the price of the security do not occur.</p><p>Merger Arbitrage Securities and Distressed Companies</p><p>A merger or other restructuring, or a tender or exchange offer, proposed or pending at the time the Fund invests in merger arbitrage securities may not be completed on the terms or within the time frame contemplated, resulting in losses to the Fund. Debt obligations of distressed companies typically are unrated, lower-rated, in default or close to default and are generally more likely to become worthless than the securities of more financially stable companies.</p><p>Foreign Securities</p><p>Investing in foreign securities typically involves more risks than investing in U.S. securities, including risks related to currency exchange rates and policies, country or government specific issues, less favorable trading practices or regulation and greater price volatility. Certain of these risks also may apply to securities of U.S. companies with significant foreign operations.</p><p>Smaller and Midsize Companies</p><p>Securities issued by smaller and midsize companies may be more volatile in price than those of larger companies, involve substantial risks and should be considered speculative. Such risks may include greater sensitivity to economic conditions, less certain growth prospects, lack of depth of management and funds for growth and development and limited or less developed product lines and markets. In addition, smaller companies may be particularly affected by interest rate increases, as they may find it more difficult to borrow money to continue or expand operations, or may have difficulty in repaying any loans.</p><p>Derivative Instruments</p><p>The performance of derivative instruments depends largely on the performance of an underlying currency, security or index and such derivative instruments often have risks similar to their underlying instrument, in addition to other risks. Derivative instruments involve costs, may be volatile and illiquid, may give rise to leverage and may involve a small initial investment relative to the risk assumed. There may also be imperfect correlation between the value of the derivative and the underlying instrument. When used for hedging, the change in value of the derivative may also not correlate specifically with the currency, security or other risk being hedged. With over-the-counter derivatives, there is the risk that the other party to the transaction will fail to perform.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Emerging market or "developing market" countries include those considered to be developing by the World Bank, the International Finance Corporation, the United Nations, or the countries' authorities, or countries with a stock market capitalization of less than 3% of the Morgan Stanley Capital International World Index. These countries typically are located in the Asia-Pacific region, Eastern Europe, Central and South America, and Africa. The Fund invests primarily in equity securities of developing market companies, primarily common and preferred stock.</p><p>The Fund's investments in equity securities may include investments in the securities of smaller and mid-size companies. The Fund also invests in American, Global, and European Depositary Receipts. The Fund, from time to time, may have significant investments in one or more countries or in particular industries or sectors, based on economic conditions. In addition to the Fund's main investments, the Fund may invest up to 20% of its net assets in the securities of issuers in developed market countries.</p><p>When choosing equity investments for the Fund, the investment manager applies a fundamental research, value-oriented, long-term approach, focusing on the market price of a company&#146;s securities relative to the investment manager&#146;s evaluation of the company&#146;s long-term earnings, asset value and cash flow potential. The investment manager also considers a company&#146;s profit and loss outlook, balance sheet strength, cash flow trends and asset value in relation to the current price.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.</p><p>Market</p><p>The market value of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.</p><p>Generally, stocks have historically outperformed other types of investments over the long term. Individual stock prices, however, tend to go up and down more dramatically. A slower-growth or recessionary economic environment could have an adverse effect on the price of the various stocks held by the Fund.</p><p>Foreign Securities</p><p>Investing in foreign securities typically involves more risks than investing in U.S. securities, and includes risks associated with: political and economic developments - the political, economic and social structures of some foreign countries may be less stable and more volatile than those in the U.S.; trading practices - government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S.; availability of information - foreign issuers may not be subject to the same disclosure, accounting and financial reporting standards and practices as U.S. issuers; limited markets - the securities of certain foreign issuers may be less liquid (harder to sell) and more volatile; and currency exchange rate fluctuations and policies. The risks of foreign investments typically are greater in less developed countries or emerging market countries.</p><p>Emerging Market Countries</p><p>The Fund&#146;s investments in emerging market countries are subject to all of the risks of foreign investing generally, and have additional heightened risks due to a lack of established legal, political, business and social frameworks to support securities markets, including: delays in settling portfolio securities transactions; currency and capital controls; greater sensitivity to interest rate changes; pervasiveness of corruption and crime; currency exchange rate volatility; and inflation, deflation or currency devaluation.</p><p>Focus</p><p>To the extent that the Fund focuses on particular countries, regions, industries, sectors or types of investment from time to time, the Fund may be subject to greater risks of adverse developments in such areas of focus than a fund that invests in a wider variety of countries, regions, industries, sectors or investments.</p><p>Smaller and Midsize Companies</p><p>Securities issued by smaller and midsize companies may be more volatile in price than those of larger companies, involve substantial risks and should be considered speculative. Such risks may include greater sensitivity to economic conditions, less certain growth prospects, lack of depth of management and funds for growth and development and limited or less developed product lines and markets. In addition, smaller companies may be particularly affected by interest rate increases, as they may find it more difficult to borrow money to continue or expand operations, or may have difficulty in repaying any loans.</p><p>Value Style Investing</p><p>A value stock may not increase in price as anticipated by the investment manager if other investors fail to recognize the company's value and bid up the price, the markets favor faster-growing companies, or the factors that the investment manager believes will increase the price of the security do not occur.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.</p><p>Market</p><p>The market value of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.</p><p>Generally, stocks have historically outperformed other types of investments over the long term. Individual stock prices, however, tend to go up and down more dramatically. A slower-growth or recessionary economic environment could have an adverse effect on the price of the various stocks held by the Fund.</p><p>Foreign Securities</p><p>Investing in foreign securities typically involves more risks than investing in U.S. securities, and includes risks associated with: political and economic developments - the political, economic and social structures of some foreign countries may be less stable and more volatile than those in the U.S.; trading practices - government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S.; availability of information - foreign issuers may not be subject to the same disclosure, accounting and financial reporting standards and practices as U.S. issuers; limited markets - the securities of certain foreign issuers may be less liquid (harder to sell) and more volatile; and currency exchange rate fluctuations and policies. The risks of foreign investments typically are greater in less developed countries or emerging market countries.</p><p>Focus</p><p>To the extent that the Fund focuses on particular countries, regions, industries, sectors or types of investment from time to time, the Fund may be subject to greater risks of adverse developments in such areas of focus than a fund that invests in a wider variety of countries, regions, industries, sectors or investments.</p><p>Value Style Investing</p><p>A value stock may not increase in price as anticipated by the investment manager if other investors fail to recognize the company's value and bid up the price, the markets favor faster-growing companies, or the factors that the investment manager believes will increase the price of the security do not occur.</p><p>Smaller and Midsize Companies</p><p>Securities issued by smaller and midsize companies may be more volatile in price than those of larger companies, involve substantial risks and should be considered speculative. Such risks may include greater sensitivity to economic conditions, less certain growth prospects, lack of depth of management and funds for growth and development and limited or less developed product lines and markets. In addition, smaller companies may be particularly affected by interest rate increases, as they may find it more difficult to borrow money to continue or expand operations, or may have difficulty in repaying any loans.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

The Fund invests predominately in bonds issued by governments and government agencies around the world. Under normal market conditions, the Fund expects to invest at least 40% of its net assets in foreign securities, and may invest without limits in emerging or developing markets.</p><p>Although the Fund may buy bonds rated in any category, it focuses on "investment grade" bonds. These are issues rated in the top four rating categories by independent rating agencies such as Standard &amp; Poor's (S&amp;P&#174;) or Moody's Investors Service (Moody's) or, if unrated, determined by the Fund's investment manager to be comparable. The Fund may invest up to 25% of its net assets in debt securities that are rated below investment grade. Generally, lower rated securities pay higher yields than more highly rated securities to compensate investors for the higher risk.</p><p>The Fund is a "non-diversified" fund, which means it generally invests a greater portion of its assets in the securities of one or more issuers and invests overall in a smaller number of issuers than a diversified fund.</p><p>For purposes of pursuing its investment goals, the Fund regularly enters into currency-related transactions involving certain derivative instruments, including currency and cross currency forwards, and currency and currency index futures contracts. The use of such derivative currency transactions may allow the Fund to obtain net long or net negative (short) exposure to selected currencies. The results of such transactions may also represent, from time to time, a significant component of the Fund&#146;s investment returns. The Fund may also enter into interest rate and credit related derivative transactions, including interest rate/bond futures contracts and swap agreements (which may include interest rate and credit default swaps) and options thereon. The use of these derivative transactions may allow the Fund to obtain net long or net negative (short) exposures to selected interest rates, countries, durations or credit risks.</p><p>The investment manager allocates the Fund's assets based upon its assessment of changing market, political and economic conditions. It will consider various factors, including evaluation of interest and currency exchange rate changes and credit risks.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.</p><p>Interest Rate</p><p>When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. In general, securities with longer maturities are more sensitive to these interest rate changes.</p><p>Foreign Securities</p><p>Investing in foreign securities typically involves more risks than investing in U.S. securities, and includes risks associated with: political and economic developments - the political, economic and social structures of some foreign countries may be less stable and more volatile than those in the U.S.; trading practices - government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S.; availability of information - foreign issuers may not be subject to the same disclosure, accounting and financial reporting standards and practices as U.S. issuers; limited markets - the securities of certain foreign issuers may be less liquid (harder to sell) and more volatile; and currency exchange rate fluctuations and policies. The risks of foreign investments typically are greater in less developed countries or emerging market countries.</p><p>Developing Market Countries</p><p>The Fund&#146;s investments in developing market countries are subject to all of the risks of foreign investing generally, and have additional heightened risks due to a lack of established legal, political, business and social frameworks to support securities markets, including: delays in settling portfolio securities transactions; currency and capital controls; greater sensitivity to interest rate changes; pervasiveness of corruption and crime; currency exchange rate volatility; and inflation, deflation or currency devaluation.</p><p>Credit</p><p>An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's credit rating may affect a security's value.</p><p>High-Yield Debt Securities</p><p>Issuers of lower-rated or "high yield" debt securities are not as strong financially as those issuing higher credit quality debt securities. These issuers are more likely to encounter financial difficulties and are more vulnerable to changes in the relevant economy, such as a recession or a sustained period of rising interest rates, that could affect their ability to make interest and principal payments when due. The prices of high yield debt securities generally fluctuate more than those of higher credit quality. High yield debt securities are generally more illiquid (harder to sell) and harder to value.</p><p>Derivative Instruments</p><p>The performance of derivative instruments depends largely on the performance of an underlying currency, security or index and such derivative instruments often have risks similar to their underlying instrument, in addition to other risks. Derivative instruments involve costs, may be volatile and illiquid, may give rise to leverage and may involve a small initial investment relative to the risk assumed. There may also be imperfect correlation between the value of the derivative and the underlying instrument. When used for hedging, the change in value of the derivative may also not correlate specifically with the currency, security or other risk being hedged. With over-the-counter derivatives, there is the risk that the other party to the transaction will fail to perform.</p><p>Income</p><p>Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.</p><p>Non-Diversification</p><p>Because the Fund is non-diversified, it may be more sensitive to economic, business, political or other changes affecting similar issuers or investments than a diversified fund, which may result in greater fluctuation in the value of the Fund&#146;s shares and greater risk of loss.</p><p>Market</p><p>The market value of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities.

The risks of foreign investments typically are greater in less developed countries or emerging market countries.</p><p>Value Style Investing</p><p>A value stock may not increase in price as anticipated by the investment manager if other investors fail to recognize the company's value and bid up the price, the markets favor faster-growing companies, or the factors that the investment manager believes will increase the price of the security do not occur.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio.
