The fund may invest in the stocks of&lt;br /&gt;companies of any market capitalization and may hold growth or value stocks or &lt;br /&gt;a blend of both. The fund&apos;s portfolio construction combines a fundamental,&lt;br /&gt;bottom-up research process with macro insights and risk management. The fund&apos;s&lt;br /&gt;portfolio managers, supported by a team of research analysts, use a disciplined&lt;br /&gt;opportunistic investment approach to identify stocks of companies that the&lt;br /&gt;portfolio managers believe are trading materially below their intrinsic market&lt;br /&gt;value, have strong or improving fundamentals and have a revaluation catalyst.&lt;br /&gt; &lt;br /&gt;The fund seeks exposure to stocks and sectors that the fund&apos;s portfolio managers&lt;br /&gt;perceive to be attractive from a valuation and fundamental standpoint. Portfolio&lt;br /&gt;position sizes and sector weightings reflect the collaborative investment process &lt;br /&gt;among the fund&apos;s portfolio managers and research analysts. The portfolio managers &lt;br /&gt;also assess and manage the overall risk profile of the fund&apos;s portfolio.&lt;/tt&gt;</rr:StrategyNarrativeTextBlock>

It is not insured or guaranteed&lt;br /&gt;by the Federal Deposit Insurance Corporation (FDIC) or any other government&lt;br /&gt;agency. It is not a complete investment program. The fund&apos;s share price fluctuates, &lt;br /&gt;sometimes dramatically, which means you could lose money.&lt;br /&gt;&lt;br /&gt;o Risks of stock investing. Stocks generally fluctuate more in value than bonds&lt;br /&gt;and may decline significantly over short time periods. There is the chance that&lt;br /&gt;stock prices overall will decline because stock markets tend to move in cycles,&lt;br /&gt;with periods of rising prices and falling prices. The market value of a stock&lt;br /&gt;may decline due to general weakness in the stock market or because of factors&lt;br /&gt;that affect the company or its particular industry.&lt;br /&gt;&lt;br /&gt;o Market sector risk. The fund may significantly overweight or underweight&lt;br /&gt;certain companies, industries or market sectors, which may cause the fund&apos;s&lt;br /&gt;performance to be more or less sensitive to developments affecting those&lt;br /&gt;companies, industries or sectors.&lt;br /&gt;&lt;br /&gt;o Growth and value stock risk. By investing in a mix of growth and value&lt;br /&gt;companies, the fund assumes the risks of both. Investors often expect growth&lt;br /&gt;companies to increase their earnings at a certain rate. If these expectations&lt;br /&gt;are not met, investors can punish the stocks inordinately, even if earnings &lt;br /&gt;do increase. In addition, growth stocks typically lack the dividend yield that &lt;br /&gt;can cushion stock prices in market downturns. Value stocks involve the risk &lt;br /&gt;that they may never reach their expected full market value, either because the &lt;br /&gt;market fails to recognize the stock&apos;s intrinsic worth, or the expected value &lt;br /&gt;was misgauged. They also may decline in price even though in theory they are &lt;br /&gt;already undervalued.&lt;br /&gt;&lt;br /&gt;o Small and midsize company risk. Small and midsize companies carry additional&lt;br /&gt;risks because the operating histories of these companies tend to be more&lt;br /&gt;limited, their earnings and revenues less predictable (and some companies may &lt;br /&gt;be experiencing significant losses), and their share prices more volatile than&lt;br /&gt;those of larger, more established companies. The shares of smaller companies&lt;br /&gt;tend to trade less frequently than those of larger, more established companies,&lt;br /&gt;which can adversely affect the pricing of these securities and the fund&apos;s&lt;br /&gt;ability to sell these securities.&lt;br /&gt;&lt;br /&gt;o Liquidity risk. When there is little or no active trading market for a&lt;br /&gt;security, the fund may not be able to sell the security in a timely manner at&lt;br /&gt;its perceived value, which could cause the fund&apos;s share price to fall.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>

Technology companies, especially&lt;br /&gt;small-cap technology companies, involve greater risk because their revenue&lt;br /&gt;and/or earnings tend to be less predictable (and some companies may be&lt;br /&gt;experiencing significant losses) and their share prices tend to be more&lt;br /&gt;volatile. Certain technology companies may have limited product lines, markets&lt;br /&gt;or financial resources, or may depend on a limited management group. In&lt;br /&gt;addition, these companies are strongly affected by worldwide technological&lt;br /&gt;developments, and their products and services may not be economically successful&lt;br /&gt;or may quickly become outdated. Investor perception may play a greater role in&lt;br /&gt;determining the day-to-day value of tech stocks than it does in other sectors.&lt;br /&gt;Fund investments made in anticipation of future products and services may&lt;br /&gt;decline dramatically in value if the anticipated products or services are&lt;br /&gt;delayed or cancelled. The risks associated with technology companies are&lt;br /&gt;magnified in the case of small-cap technology companies. The shares of smaller&lt;br /&gt;technology companies tend to trade less frequently than those of larger, more&lt;br /&gt;established companies, which can have an adverse effect on the pricing of these&lt;br /&gt;securities and on the fund&apos;s ability to sell these securities.&lt;br /&gt; &lt;br /&gt;o Risks of stock investing. Stocks generally fluctuate more in value than bonds&lt;br /&gt;and may decline significantly over short time periods. There is the chance that&lt;br /&gt;stock prices overall will decline because stock markets tend to move in cycles,&lt;br /&gt;with periods of rising prices and falling prices. The market value of a stock&lt;br /&gt;may decline due to general weakness in the stock market or because of factors&lt;br /&gt;that affect the company or its particular industry.&lt;br /&gt; &lt;br /&gt;o Small and midsize company risk. Small and midsize companies carry additional&lt;br /&gt;risks because the operating histories of these companies tend to be more&lt;br /&gt;limited, their earnings and revenues less predictable (and some companies may be&lt;br /&gt;experiencing significant losses), and their share prices more volatile than&lt;br /&gt;those of larger, more established companies. The shares of smaller companies&lt;br /&gt;tend to trade less frequently than those of larger, more established companies,&lt;br /&gt;which can adversely affect the pricing of these securities and the fund&apos;s&lt;br /&gt;ability to sell these securities.&lt;br /&gt; &lt;br /&gt;o Growth stock risk. Investors often expect growth companies to increase their&lt;br /&gt;earnings at a certain rate. If these expectations are not met, investors can&lt;br /&gt;punish the stocks inordinately, even if earnings do increase. In addition,&lt;br /&gt;growth stocks may lack the dividend yield that may cushion stock prices in&lt;br /&gt;market downturns.&lt;br /&gt; &lt;br /&gt;o Foreign investment risk. Special risks associated with investments in foreign&lt;br /&gt;issuers include exposure to currency fluctuations, less liquidity, less developed &lt;br /&gt;or less efficient trading markets, lack of comprehensive company information, &lt;br /&gt;political and economic instability and differing auditing and legal standards. &lt;br /&gt;Investments denominated in foreign currencies are subject to the risk that such &lt;br /&gt;currencies will decline in value relative to the U.S. dollar and affect the value &lt;br /&gt;of these investments held by the fund.&lt;br /&gt; &lt;br /&gt;o Liquidity risk. When there is little or no active trading market for a security, &lt;br /&gt;the fund may not be able to sell the security in a timely manner at its perceived &lt;br /&gt;value, which could cause the fund&apos;s share price to fall.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>

It is not insured or guaranteed&lt;br /&gt;by the Federal Deposit Insurance Corporation (FDIC) or any other government&lt;br /&gt;agency. It is not a complete investment program. The fund&apos;s share price fluctuates, &lt;br /&gt;sometimes dramatically, which means you could lose money.&lt;br /&gt; &lt;br /&gt;o Risks of stock investing. Stocks generally fluctuate more in value than bonds&lt;br /&gt;and may decline significantly over short time periods. There is the chance that&lt;br /&gt;stock prices overall will decline because stock markets tend to move in cycles,&lt;br /&gt;with periods of rising prices and falling prices. The market value of a stock&lt;br /&gt;may decline due to general weakness in the stock market or because of factors&lt;br /&gt;that affect the company or its particular industry.&lt;br /&gt; &lt;br /&gt;o Small and midsize company risk. Small and midsize companies carry additional&lt;br /&gt;risks because the operating histories of these companies tend to be more&lt;br /&gt;limited, their earnings and revenues less predictable (and some companies may &lt;br /&gt;be experiencing significant losses), and their share prices more volatile than&lt;br /&gt;those of larger, more established companies. The shares of smaller companies&lt;br /&gt;tend to trade less frequently than those of larger, more established companies,&lt;br /&gt;which can adversely affect the pricing of these securities and the fund&apos;s&lt;br /&gt;ability to sell these securities.&lt;br /&gt; &lt;br /&gt;o Growth and value stock risk. By investing in a mix of growth and value&lt;br /&gt;companies, the fund assumes the risks of both. Investors often expect growth&lt;br /&gt;companies to increase their earnings at a certain rate. If these expectations&lt;br /&gt;are not met, investors can punish the stocks inordinately, even if earnings &lt;br /&gt;do increase. In addition, growth stocks typically lack the dividend yield that &lt;br /&gt;can cushion stock prices in market downturns. Value stocks involve the risk &lt;br /&gt;that they may never reach their expected full market value, either because the &lt;br /&gt;market fails to recognize the stock&apos;s intrinsic worth, or the expected value was&lt;br /&gt;misgauged. They also may decline in price even though in theory they are already&lt;br /&gt;undervalued.&lt;br /&gt; &lt;br /&gt;o Liquidity risk. When there is little or no active trading market for a security, &lt;br /&gt;the fund may not be able to sell the security in a timely manner at its perceived &lt;br /&gt;value, which could cause the fund&apos;s share price to fall.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>

The fund&apos;s share price fluctuates, &lt;br /&gt;sometimes dramatically, which means you could lose money.&lt;br /&gt; &lt;br /&gt;o Risks of stock investing. Stocks generally fluctuate more in value than bonds&lt;br /&gt;and may decline significantly over short time periods. There is the chance that&lt;br /&gt;stock prices overall will decline because stock markets tend to move in cycles,&lt;br /&gt;with periods of rising prices and falling prices. The market value of a stock&lt;br /&gt;may decline due to general weakness in the stock market or because of factors&lt;br /&gt;that affect the company or its particular industry.&lt;br /&gt; &lt;br /&gt;o Value stock risk. Value stocks involve the risk that they may never reach&lt;br /&gt;their expected full market value, either because the market fails to recognize&lt;br /&gt;the stock&apos;s intrinsic worth or the expected value was misgauged. They also may&lt;br /&gt;decline in price even though in theory they are already undervalued.&lt;br /&gt; &lt;br /&gt;o Market sector risk. The fund may significantly overweight or underweight&lt;br /&gt;certain companies, industries or market sectors, which may cause the fund&apos;s&lt;br /&gt;performance to be more or less sensitive to developments affecting those&lt;br /&gt;companies, industries or sectors.&lt;br /&gt; &lt;br /&gt;o Foreign investment risk. Special risks associated with investments in foreign&lt;br /&gt;issuers include exposure to currency fluctuations, less liquidity, less developed &lt;br /&gt;or less efficient trading markets, lack of comprehensive company information, &lt;br /&gt;political and economic instability and differing auditing and legal standards. &lt;br /&gt;Investments denominated in foreign currencies are subject to the risk that such &lt;br /&gt;currencies will decline in value relative to the U.S. dollar and affect the value &lt;br /&gt;of these investments held by the fund.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>

Stocks &lt;br /&gt;are selected for the fund&apos;s portfolio based primarily on bottom-up &lt;br /&gt;fundamental analysis. The fund&apos;s portfolio managers use a disciplined &lt;br /&gt;investment process that relies, in general, on proprietary fundamental &lt;br /&gt;research and valuation. Generally, elements of the process include &lt;br /&gt;analysis of mid-cycle business prospects, estimation of the intrinsic &lt;br /&gt;value of the company and the identification of a revaluation catalyst.&lt;br /&gt;In general, the fund seeks exposure to securities and sectors that the &lt;br /&gt;fund&apos;s portfolio managers perceive to be attractive from a valuation &lt;br /&gt;and fundamental standpoint.&lt;/tt&gt;</rr:StrategyNarrativeTextBlock>

It is not insured or guaranteed&lt;br /&gt;by the Federal Deposit Insurance Corporation (FDIC) or any other government&lt;br /&gt;agency. It is not a complete investment program. The fund&apos;s share price fluctuates, &lt;br /&gt;sometimes dramatically, which means you could lose money.&lt;br /&gt; &lt;br /&gt;o Risks of stock investing. Stocks generally fluctuate more in value than bonds&lt;br /&gt;and may decline significantly over short time periods. There is the chance that&lt;br /&gt;stock prices overall will decline because stock markets tend to move in cycles,&lt;br /&gt;with periods of rising prices and falling prices. The market value of a stock&lt;br /&gt;may decline due to general weakness in the stock market or because of factors&lt;br /&gt;that affect the company or its particular industry.&lt;br /&gt;&lt;br /&gt;o Small and midsize company risk. Small and midsize companies carry additional&lt;br /&gt;risks because the operating histories of these companies tend to be more&lt;br /&gt;limited, their earnings and revenues less predictable (and some companies may be&lt;br /&gt;experiencing significant losses), and their share prices more volatile than&lt;br /&gt;those of larger, more established companies. The shares of smaller companies&lt;br /&gt;tend to trade less frequently than those of larger, more established companies,&lt;br /&gt;which can adversely affect the pricing of these securities and the fund&apos;s&lt;br /&gt;ability to sell these securities.&lt;br /&gt; &lt;br /&gt;o Growth and value stock risk. By investing in a mix of growth and value&lt;br /&gt;companies, the fund assumes the risks of both. Investors often expect growth&lt;br /&gt;companies to increase their earnings at a certain rate. If these expectations&lt;br /&gt;are not met, investors can punish the stocks inordinately, even if earnings &lt;br /&gt;do increase. In addition, growth stocks typically lack the dividend yield that &lt;br /&gt;can cushion stock prices in market downturns. Value stocks involve the risk &lt;br /&gt;that they may never reach their expected full market value, either because the &lt;br /&gt;market fails to recognize the stock&apos;s intrinsic worth, or the expected value &lt;br /&gt;was misgauged. They also may decline in price even though in theory they are &lt;br /&gt;already undervalued.&lt;br /&gt; &lt;br /&gt;o Market sector risk. The fund may significantly overweight or underweight&lt;br /&gt;certain companies, industries or market sectors, which may cause the fund&apos;s&lt;br /&gt;performance to be more or less sensitive to developments affecting those&lt;br /&gt;companies, industries or sectors.&lt;br /&gt; &lt;br /&gt;o Liquidity risk. When there is little or no active trading market for a&lt;br /&gt;security, the fund may not be able to sell the security in a timely manner at&lt;br /&gt;its perceived value, which could cause the fund&apos;s share price to fall.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>

The fund&apos;s portfolio&lt;br /&gt;managers identify potential investments through extensive quantitative and&lt;br /&gt;fundamental research. The fund focuses on individual stock selection (a&lt;br /&gt;"bottom-up" approach), emphasizing three key factors: relative value, business&lt;br /&gt;health, and business momentum.&lt;br /&gt; &lt;br /&gt;In constructing the fund&apos;s portfolio, the fund&apos;s portfolio managers use an&lt;br /&gt;opportunistic value approach to identify stocks whose current market prices&lt;br /&gt;trade at a large discount to their intrinsic value, as calculated by the&lt;br /&gt;portfolio managers. Intrinsic value is based on the combination of the valuation&lt;br /&gt;assessment of the company&apos;s operating divisions with its economic balance sheet.&lt;br /&gt;The opportunistic value style attempts to benefit from valuation inefficiencies&lt;br /&gt;and underappreciated fundamental prospects present in the marketplace. To do&lt;br /&gt;this, the portfolio managers use mid-cycle estimates, growth prospects, the&lt;br /&gt;identification of a revaluation catalyst and competitive advantages as some of&lt;br /&gt;the factors in the valuation assessment. Additionally, a company&apos;s stated and&lt;br /&gt;hidden liabilities and assets are included in the portfolio managers&apos; economic&lt;br /&gt;balance sheet calculation for the company.&lt;/tt&gt;</rr:StrategyNarrativeTextBlock>

It is not insured or guaranteed&lt;br /&gt;by the Federal Deposit Insurance Corporation (FDIC) or any other government&lt;br /&gt;agency. It is not a complete investment program. The fund&apos;s share price fluctuates, &lt;br /&gt;sometimes dramatically, which means you could lose money.&lt;br /&gt; &lt;br /&gt;o Risks of stock investing. Stocks generally fluctuate more in value than bonds&lt;br /&gt;and may decline significantly over short time periods. There is the chance that&lt;br /&gt;stock prices overall will decline because stock markets tend to move in cycles,&lt;br /&gt;with periods of rising prices and falling prices. The market value of a stock&lt;br /&gt;may decline due to general weakness in the stock market or because of factors&lt;br /&gt;that affect the company or its particular industry.&lt;br /&gt; &lt;br /&gt;o Small and midsize company risk. Small and midsize companies carry additional&lt;br /&gt;risks because the operating histories of these companies tend to be more&lt;br /&gt;limited, their earnings and revenues less predictable (and some companies may &lt;br /&gt;be experiencing significant losses), and their share prices more volatile than&lt;br /&gt;those of larger, more established companies. The shares of smaller companies&lt;br /&gt;tend to trade less frequently than those of larger, more established companies,&lt;br /&gt;which can adversely affect the pricing of these securities and the fund&apos;s&lt;br /&gt;ability to sell these securities.&lt;br /&gt; &lt;br /&gt;o Value stock risk. Value stocks involve the risk that they may never reach&lt;br /&gt;their expected full market value, either because the market fails to recognize&lt;br /&gt;the stock&apos;s intrinsic worth or the expected value was misgauged. They also may&lt;br /&gt;decline in price even though in theory they are already undervalued.&lt;br /&gt; &lt;br /&gt;o Market sector risk. The fund may significantly overweight or underweight&lt;br /&gt;certain companies, industries or market sectors, which may cause the fund&apos;s&lt;br /&gt;performance to be more or less sensitive to developments affecting those&lt;br /&gt;companies, industries or sectors.&lt;br /&gt; &lt;br /&gt;o Liquidity risk. When there is little or no active trading market for a&lt;br /&gt;security, the fund may not be able to sell the security in a timely manner &lt;br /&gt;at its perceived value, which could cause the fund&apos;s share price to fall.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>

In selecting stocks, the fund&apos;s&lt;br /&gt;portfolio managers identify potential investments through extensive quantitative&lt;br /&gt;and fundamental research. Emphasizing individual stock selection rather than&lt;br /&gt;economic and industry trends, the fund focuses on three key factors: value,&lt;br /&gt;business health and business momentum.&lt;/tt&gt;</rr:StrategyNarrativeTextBlock>

It is not insured or guaranteed&lt;br /&gt;by the Federal Deposit Insurance Corporation (FDIC) or any other government&lt;br /&gt;agency. It is not a complete investment program. The fund&apos;s share price fluctuates, &lt;br /&gt;sometimes dramatically, which means you could lose money.&lt;br /&gt; &lt;br /&gt;o Foreign investment risk. The fund&apos;s performance may be influenced by&lt;br /&gt;political, social and economic factors affecting investments in foreign issuers.&lt;br /&gt;Special risks associated with investments in foreign issuers include exposure to&lt;br /&gt;currency fluctuations, less liquidity, less developed or less efficient trading&lt;br /&gt;markets, lack of comprehensive company information, political and economic&lt;br /&gt;instability and differing auditing and legal standards. Investments denominated&lt;br /&gt;in foreign currencies are subject to the risk that such currencies will decline&lt;br /&gt;in value relative to the U.S. dollar and affect the value of these investments&lt;br /&gt;held by the fund.&lt;br /&gt; &lt;br /&gt;o Foreign currency risk. Investments in foreign currencies are subject to the&lt;br /&gt;risk that those currencies will decline in value relative to the U.S. dollar or,&lt;br /&gt;in the case of hedged positions, that the U.S. dollar will decline relative to&lt;br /&gt;the currency being hedged. Currency exchange rates may fluctuate significantly&lt;br /&gt;over short periods of time. Foreign currencies are also subject to risks caused&lt;br /&gt;by inflation, interest rates, budget deficits and low savings rates, political&lt;br /&gt;factors and government intervention and controls.&lt;br /&gt; &lt;br /&gt;o Risks of stock investing. Stocks generally fluctuate more in value than bonds&lt;br /&gt;and may decline significantly over short time periods. There is the chance that&lt;br /&gt;stock prices overall will decline because stock markets tend to move in cycles,&lt;br /&gt;with periods of rising prices and falling prices. The market value of a stock&lt;br /&gt;may decline due to general weakness in the stock market or because of factors&lt;br /&gt;that affect the company or its particular industry.&lt;br /&gt; &lt;br /&gt;o Value stock risk. Value stocks involve the risk that they may never reach&lt;br /&gt;their expected full market value, either because the market fails to recognize&lt;br /&gt;the stock&apos;s intrinsic worth or the expected value was misgauged. They also may&lt;br /&gt;decline in price even though in theory they are already undervalued.&lt;br /&gt; &lt;br /&gt;o Liquidity risk. When there is little or no active trading market for a&lt;br /&gt;security, the fund may not be able to sell the security in a timely manner at&lt;br /&gt;its perceived value, which could cause the fund&apos;s share price to fall.&lt;br /&gt;Investments in foreign securities tend to have greater exposure to liquidity&lt;br /&gt;risk than domestic securities.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>
