The Fund may invest in derivative instruments (by taking long and/or short positions) for different purposes, including hedging (to offset risks associated with an investment, currency exposure, or market conditions) and to earn income and enhance returns.

The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.<br/><br/><b><i>Market Risk</i>.</b> The value of the Fund&#8217;s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio managers&#8217; belief about a company&#8217;s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund&#8217;s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.<br/><br/><b><i>Growth Securities Risk</i>.</b> The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be &#8220;growth&#8221; companies may be more volatile than other stocks and may involve special risks. If the portfolio managers&#8217; perception of a company&#8217;s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund&#8217;s returns. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, &#8220;growth&#8221; stocks may perform differently from the market as a whole and other types of securities.<br/><br/><b><i>Foreign Exposure Risk</i>.</b> The Fund may have significant exposure to foreign markets as a result of its investments in foreign securities, including investments in emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund&#8217;s performance than it would in a more geographically diversified portfolio. The Fund&#8217;s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.<br/><br/><b><i>Derivatives Risk</i>.</b> Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative&#8217;s original cost, and can therefore involve leverage. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations.<br/><br/><i>An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.</i> 0.005 0 0.0048 <b>PERFORMANCE INFORMATION</b> The following information provides some indication of the risks of investing in the Fund by showing how the Fund&#8217;s performance has varied over time.

The performance shown for Class D Shares for periods prior to February 16, 2010, reflects the performance of the Fund&#8217;s former Class J Shares, calculated using the fees and expenses in effect during the periods shown, net of any applicable fee and expense limitations or waivers. If Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for periods following the Fund&#8217;s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any applicable fee and expense limitations or waivers.<br/><br/>The bar chart depicts the change in performance from year to year during the periods indicated.

The portfolio manager emphasizes investments in companies with attractive price/free cash flow, which is the relationship between the price of a stock and the company&#8217;s available cash from operations, minus capital expenditures. The portfolio manager will typically seek attractively valued companies that are improving their free cash flow and returns on invested capital.

The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.<br/><br/><b><i>Market Risk</i>.</b> The value of the Fund&#8217;s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager&#8217;s belief about a company&#8217;s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund&#8217;s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.<br/><br/><b><i>Growth Securities Risk</i>.</b> The Fund invests in companies after assessing their growth potential.

If the portfolio manager&#8217;s perception of a company&#8217;s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund&#8217;s returns. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, &#8220;growth&#8221; stocks may perform differently from the market as a whole and other types of securities.<br/><br/><b><i>Fixed-Income Securities Risk</i>.</b> The Fund may hold debt and other fixed-income securities to generate income. Typically, the values of fixed-income securities change inversely with prevailing interest rates. Therefore, a fundamental risk of fixed-income securities is interest rate risk, which is the risk that their value will generally decline as prevailing interest rates rise, which may cause the Fund&#8217;s net asset value to likewise decrease. How specific fixed-income securities may react to changes in interest rates will depend on the specific characteristics of each security. Fixed-income securities are also subject to credit risk, prepayment risk, valuation risk, and liquidity risk. Credit risk is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default. Prepayment risk is the risk that during periods of falling interest rates, certain fixed-income securities with higher interest rates, such as mortgage- and asset-backed securities, may be prepaid by their issuers thereby reducing the amount of interest payments. Valuation risk is the risk that one or more of the fixed-income securities in which the Fund invests are priced incorrectly due to factors such as incomplete data, market instability, or human error. Liquidity risk is the risk that fixed-income securities may be difficult or impossible to sell at the time that the portfolio manager would like or at the price that the portfolio manager believes the security is currently worth.<br/><br/><b><i>Foreign Exposure Risk</i>.</b> The Fund may have exposure to foreign markets as a result of its investments in foreign securities, including investments in emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country.

Common stocks tend to be more volatile than many other investment choices.<br/><br/> <b><i>Value Investing Risk</i>.</b>&nbsp;Because different types of stocks tend to shift in and out of favor depending on market and economic conditions, &#8220;value&#8221; stocks may perform differently than other types of stocks and from the market as a whole, and can continue to be undervalued by the market for long periods of time. It is also possible that a value stock will never appreciate to the extent expected by the Fund&#8217;s portfolio manager.<br/><br/><b><i>Market Risk</i>.</b>&nbsp;The value of the Fund&#8217;s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager&#8217;s belief about a company&#8217;s intrinsic worth is incorrect.

It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money. <br/><br/><b><i>Growth Securities Risk</i>.</b>&nbsp;The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be &#8220;growth&#8221; companies may be more volatile than other stocks and may involve special risks. If the portfolio manager&#8217;s perception of a company&#8217;s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund&#8217;s returns. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, &#8220;growth&#8221; stocks may perform differently from the market as a whole and other types of securities.<br/><br/><b><i>Special Situations Risk</i>.</b>&nbsp;The Fund may invest in companies that demonstrate special situations or turnarounds, meaning companies that have experienced significant business problems but are believed to have favorable prospects for recovery. Special situations may include significant changes in a company&#8217;s allocation of its existing capital, a restructuring of assets, or a redirection of free cash flow. Special situations may also result from: (i)&nbsp;significant changes in industry structure through regulatory developments or shifts in competition; (ii)&nbsp;a new or improved product, service, operation, or technological advance; (iii)&nbsp;changes in senior management or other extraordinary corporate event; (iv)&nbsp;differences in market supply of and demand for the security; or (v)&nbsp;significant changes in cost structure. Investments in &#8220;special situations&#8221; companies can present greater risks than investments in companies not experiencing special situations, and the Fund&#8217;s performance could be adversely impacted if the securities selected decline in value or fail to appreciate in value. <br/><br/><b><i>Nondiversification Risk</i>.&nbsp;</b>The Fund is classified as nondiversified under the Investment Company Act of 1940, as amended. This gives the Fund&#8217;s portfolio manager more flexibility to hold larger positions in a smaller number of securities. As a result, an increase or decrease in the value of a single security held by the Fund may have a greater impact on the Fund&#8217;s net asset value and total return. <br/><br/><b><i>Foreign Exposure Risk</i>.</b>&nbsp;The Fund may have significant exposure to foreign markets as a result of its investments in foreign securities, including investments in emerging markets, which can be more volatile than the U.S.&nbsp;markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund&#8217;s performance than it would in a more geographically diversified portfolio. The Fund&#8217;s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries. <br/><br/><b><i>Derivatives Risk</i>.</b>&nbsp;Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative&#8217;s original cost, and can therefore involve leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. To the extent the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund&#8217;s losses are theoretically unlimited. <br/><br/><b><i>Real Estate Securities Risk</i>.</b>&nbsp;The Fund may be affected by risks associated with investments in real estate-related securities. The value of securities of issuers in the real estate and real estate-related industries, including real estate investment trusts, is sensitive to changes in real estate values and rental income, property taxes, interest rates, tax and regulatory requirements, supply and demand, and the management skill and creditworthiness of the issuer. These factors may impact the Fund&#8217;s investments in foreign real estate markets differently than U.S.&nbsp;real estate markets. <br/><br/><i>An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.</i> 0.0144 0.0219 0.0072 0.0149 0.0107 0.0124 <b>Portfolio Turnover: </b> <i>An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.</i> The Fund pays transaction costs, such as commissions, when it buys and sells securities (or &#8220;turns over&#8221; its portfolio).

The Fund may also invest in foreign equity and debt securities, which may include investments in emerging markets.<br/><br/>Janus Capital&#8217;s equity research analysts, overseen by the Portfolio Oversight Team led by Janus Capital&#8217;s Director of Equity Research James P. Goff (the &#8220;Research Team&#8221;), select investments for the Fund. The Research Team, comprised of sector specialists, conducts fundamental analysis with a focus on &#8220;bottom up&#8221; research, quantitative modeling, and valuation analysis. Using this research process, analysts rate their stocks based upon attractiveness. Analysts bring their high-conviction ideas to their respective sector teams. Sector teams compare the appreciation and risk potential of each of the team&#8217;s high-conviction ideas and construct a sector portfolio that is intended to maximize the best risk-reward opportunities. Although the Research Team may find high-conviction investment ideas anywhere in the world, the Research Team emphasizes investments in securities of U.S.-based issuers.<br/><br/>Positions may be sold when, among other things, there is no longer high conviction in the return potential of the investment or if the risk characteristics have caused a re-evaluation of the opportunity. This may occur if the stock has appreciated and reflects the anticipated value, if another company represents a better risk-reward opportunity, or if the investment&#8217;s fundamental characteristics deteriorate. Securities may also be sold from the portfolio to rebalance sector weightings.<br/><br/>Mr. Goff oversees the investment process and is responsible for the day-to-day management of the Fund. It is expected that the Fund will be broadly diversified among a variety of industry sectors. The Fund intends to be fully invested under normal circumstances. However, under unusual circumstances, if the Research Team does not have high conviction in enough investment opportunities, the Fund&#8217;s uninvested assets may be held in cash or similar instruments. <b>Annual Total Returns for Class D Shares</b> (calendar year-end) 2013-01-28 0.0075 <b>PERFORMANCE INFORMATION </b> 0.0075 <b>PRINCIPAL INVESTMENT RISKS</b> 0.0075 <b>Janus Triton Fund</b> seeks long-term growth of capital. 0.0075 <b>FUND SUMMARY</b><br/><br/><b>Janus Fund</b> 0.0075 0.0109 74 0.0183 The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period.

The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.<br /><br /><b><i>Market Risk.</i></b> The value of the Fund&#8217;s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager&#8217;s belief about a company&#8217;s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund&#8217;s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.<br /><br /><b><i>Growth Securities Risk.</i></b> The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be &#8220;growth&#8221; companies may be more volatile than other stocks and may involve special risks. If the portfolio manager&#8217;s perception of a company&#8217;s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund&#8217;s returns.

As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity.

The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.<br /><br /><b><i>Market Risk.</i></b> The value of the Fund&#8217;s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager&#8217;s belief about a company&#8217;s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund&#8217;s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.<br /><br /><b><i>Growth Securities Risk.</i></b> The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be &#8220;growth&#8221; companies may be more volatile than other stocks and may involve special risks. If the portfolio manager&#8217;s perception of a company&#8217;s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund&#8217;s returns. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, &#8220;growth&#8221; stocks may perform differently from the market as a whole and other types of securities.<br /><br /> <b><i> Fixed-Income Securities Risk.</i></b> The Fund may hold debt and other fixed-income securities to generate income. Typically, the values of fixed-income securities change inversely with prevailing interest rates. Therefore, a fundamental risk of fixed-income securities is interest rate risk, which is the risk that their value will generally decline as prevailing interest rates rise, which may cause the Fund&#8217;s net asset value to likewise decrease. How specific fixed-income securities may react to changes in interest rates will depend on the specific characteristics of each security. Fixed-income securities are also subject to credit risk, prepayment risk, valuation risk, and liquidity risk. Credit risk is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default. Prepayment risk is the risk that during periods of falling interest rates, certain fixed-income securities with higher interest rates, such as mortgage- and asset-backed securities, may be prepaid by their issuers thereby reducing the amount of interest payments. Valuation risk is the risk that one or more of the fixed-income securities in which the Fund invests are priced incorrectly due to factors such as incomplete data, market instability, or human error. Liquidity risk is the risk that fixed-income securities may be difficult or impossible to sell at the time that the portfolio manager would like or at the price that the portfolio manager believes the security is currently worth.<br /><br /><b><i>Foreign Exposure Risk.</i></b> The Fund may have exposure to foreign markets as a result of its investments in foreign securities, including investments in emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund&#8217;s performance than it would in a more geographically diversified portfolio. The Fund&#8217;s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries. <br /><br /><i>An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.</i> The biggest risk is that the Fund&#8217;s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.<br/><br/><b><i>Market Risk</i>.</b> The value of the Fund&#8217;s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager&#8217;s belief about a company&#8217;s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund&#8217;s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money. <br/><br/><b><i>Growth Securities Risk</i>.</b> The Fund invests in companies after assessing their growth potential.

In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, &#8220;growth&#8221; stocks may perform differently from the market as a whole and other types of securities.<br/><br/><b><i>Nondiversification Risk</i>. </b>The Fund is classified as nondiversified under the Investment Company Act of 1940, as amended. This gives the Fund&#8217;s portfolio manager more flexibility to hold larger positions in a smaller number of securities. As a result, an increase or decrease in the value of a single security held by the Fund may have a greater impact on the Fund&#8217;s net asset value and total return.<br/><br/><b><i>Foreign Exposure Risk</i>.</b> The Fund may have significant exposure to foreign markets as a result of its investments in foreign securities, including investments in emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity.

The Fund&#8217;s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.<br/><br/><b><i>Derivatives Risk</i>.</b> Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative&#8217;s original cost, and can therefore involve leverage. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations. <br/><br/><i>An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.</i> 0.0575 0 The Fund pursues its investment objective by normally investing primarily in a core group of 20-30 common stocks selected for their growth potential. The Fund may also invest in foreign equity and debt securities, which may include investments in emerging markets. <br/><br/>The portfolio manager applies a &#8220;bottom up&#8221; approach in choosing investments.

The Fund normally invests at least 25% of its assets in fixed-income senior securities. Fixed-income securities may include corporate debt securities, U.S. Government obligations, mortgage-backed securities and other mortgage-related products, and short-term securities. The Fund may also invest in foreign equity and debt securities, which may include investments in emerging markets. As of September 30, 2012, approximately 55.8% of the Fund&#8217;s assets were held in equity securities.<br /><br />In choosing investments for the Fund, the portfolio managers apply a &#8220;bottom up&#8221; approach with one portfolio manager focusing on the equity portion of the Fund and the other portfolio manager focusing on the fixed-income portion of the Fund. With respect to corporate issuers, the portfolio managers look at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund&#8217;s investment policies. The portfolio managers may also consider economic factors, such as the effect of interest rates on certain of the Fund&#8217;s fixed-income investments. The portfolio managers share day-to-day responsibility for the Fund&#8217;s investments. 0.51 466 902 0.0025 576 The Core Growth Index is an internally-calculated, hypothetical combination of unmanaged indices that combines total returns from the Russell 1000<sup>&#174;</sup> Growth Index (50%) and the S&amp;P 500<sup>&#174;</sup> Index (50%). This index is used to calculate the performance fee adjustment.<br/><br/>After-tax returns are calculated using distributions for the Fund&#8217;s Class D Shares for the periods following February 16, 2010; and for the Fund&#8217;s Class J Shares, the predecessor share class, for the periods prior to February 16, 2010. If Class D Shares of the Fund had been available during these earlier periods, distributions may have been different and thus, after-tax returns may have been different from those shown. After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes.

Common stocks tend to be more volatile than many other investment choices.<br /><br /><b><i>Market Risk.</i></b> The value of the Fund&#8217;s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio managers&#8217; belief about a company&#8217;s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund&#8217;s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.<br /><br /><b><i>Growth Securities Risk.</i></b> The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be &#8220;growth&#8221; companies may be more volatile than other stocks and may involve special risks. If the portfolio managers&#8217; perception of a company&#8217;s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund&#8217;s returns. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, &#8220;growth&#8221; stocks may perform differently from the market as a whole and other types of securities.<br /><br /><b><i>Fixed-Income Securities Risk.</i></b> The Fund may hold debt and other fixed-income securities to generate income. Typically, the values of fixed-income securities change inversely with prevailing interest rates. Therefore, a fundamental risk of fixed-income securities is interest rate risk, which is the risk that their value will generally decline as prevailing interest rates rise, which may cause the Fund&#8217;s net asset value to likewise decrease. How specific fixed-income securities may react to changes in interest rates will depend on the specific characteristics of each security. Fixed-income securities are also subject to credit risk, prepayment risk, valuation risk, and liquidity risk. Credit risk is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default. Prepayment risk is the risk that during periods of falling interest rates, certain fixed-income securities with higher interest rates, such as mortgage- and asset-backed securities, may be prepaid by their issuers thereby reducing the amount of interest payments. Valuation risk is the risk that one or more of the fixed-income securities in which the Fund invests are priced incorrectly due to factors such as incomplete data, market instability, or human error. Liquidity risk is the risk that fixed-income securities may be difficult or impossible to sell at the time that the portfolio managers would like or at the price that the portfolio managers believe the security is currently worth.<br /><br /><b><i>Mortgage-Backed Securities Risk.</i></b> Mortgage-backed securities tend to be more sensitive to changes in interest rates than other types of securities. Investments in mortgage-backed securities are subject to both extension risk, where borrowers extend the duration of their mortgages in times of rising interest rates, and prepayment risk, where borrowers pay off their mortgages sooner than expected in times of declining interest rates. These risks may reduce the Fund&#8217;s returns. In addition, investments in mortgage-backed securities, including those comprised of subprime mortgages, may be subject to a higher degree of credit risk, valuation risk, and liquidity risk than various other types of fixed-income securities.<br /><br /><b><i>Foreign Exposure Risk.</i></b> The Fund may have exposure to foreign markets as a result of its investments in foreign securities, including investments in emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund&#8217;s performance than it would in a more geographically diversified portfolio. To the extent the Fund invests in foreign debt securities, such investments are sensitive to changes in interest rates. Additionally, investments in securities of foreign governments involve the risk that a foreign government may not be willing or able to pay interest or repay principal when due. The Fund&#8217;s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.<br /><br /><b><i>Sovereign Debt Risk.</i></b> The Fund may invest in U.S. and foreign government debt securities (&#8220;sovereign debt&#8221;). Investments in U.S. sovereign debt are considered low risk. However, investments in non-U.S. sovereign debt can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor&#8217;s willingness or ability to satisfy its debt obligation may be affected by various factors including, but not limited to, its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, and the relative size of its debt position in relation to its economy as a whole. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which the Fund may collect all or part of the sovereign debt that a governmental entity has not repaid.<br /><br /><b><i>High-Yield/High-Risk Bond Risk. </i></b> High-yield/high-risk bonds may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value.<br /><br /><i>An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.</i> After-tax returns are calculated using distributions for the Fund&#8217;s Class D Shares for the periods following February 16, 2010; and for the Fund&#8217;s Class J Shares, the predecessor share class, for the periods prior to February 16, 2010.

The portfolio manager emphasizes investments in companies with attractive price/free cash flow, which is the relationship between the price of a stock and the company&#8217;s available cash from operations, minus capital expenditures. The portfolio manager will typically seek attractively valued companies that are improving their free cash flow and returns on invested capital. Such companies may also include special situations companies that are experiencing management changes and/or are currently out of favor. The Fund may also invest in foreign equity and debt securities, which may include investments in emerging markets.<br/><br/>The portfolio manager applies a &#8220;bottom up&#8221; approach in choosing investments. In other words, the portfolio manager looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund&#8217;s investment policies.<br/><br/>The Fund may invest in equity and debt securities of U.S. and non-U.S. real estate-related companies. Such companies may include those in the real estate industry or real estate-related industries. These securities may include common stocks, preferred stocks, and other equity securities including, but not limited to, real estate investment trusts and similar real estate investment trust-like entities, such as entities that have real estate investment characteristics.<br/><br/>The Fund may also take long or short positions in derivatives, which are instruments that have a value derived from, or directly linked to, an underlying asset, such as equity securities, fixed-income securities, commodities, currencies, interest rates, or market indices. For purposes of meeting its 80% investment policy, the Fund may include derivatives that have characteristics similar to the securities in which the Fund may directly invest. The types of derivatives in which the Fund may invest include options, futures, swaps, warrants, and forward exchange contracts. The Fund may use derivatives to hedge, to earn income or enhance returns, as a substitute for securities in which the Fund invests, to increase or decrease the Fund&#8217;s exposure to a particular market, to adjust the Fund&#8217;s currency exposure relative to its benchmark index, to gain access to foreign markets where direct investment may be restricted or unavailable, or to manage the Fund&#8217;s risk profile. The Fund&#8217;s exposure to derivatives will vary, is not limited to those derivatives listed, and could be significant at times. <i>janus.com/allfunds</i> <i>The Fund&#8217;s past performance (before and after taxes) does not necessarily indicate how it will perform in the future.</i> <b>PRINCIPAL INVESTMENT RISKS</b> <b>Annual Total Returns for Class D Shares</b> (calendar year-end) 680 189 126 89 0.0575 101 <b>Best Quarter:&nbsp;&nbsp;</b>Third Quarter 2009&nbsp;&nbsp;<b>10.97%&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Worst Quarter:&nbsp;&nbsp;</b>Third Quarter 2011&nbsp;&nbsp;<b>&#8722;11.02%</b> 902 585 393 Class D 278 315 <b>Average Annual Total Returns</b> (periods ended 12/31/12) The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions.

The after-tax return information shown above does not apply to Fund shares held through a tax-deferred account, such as a 401(k) plan or an IRA. 0.4999 The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets in equity securities of Asian issuers (excluding Japanese issuers). An Asian issuer is generally considered to be any company that (i) is incorporated or has its principal business activities in an Asian country; (ii) is primarily listed on the trading market of an Asian country; or (iii) derives 50% or more of its revenue from, or has 50% or more of its assets in, one or more Asian countries. The Fund considers &#8220;Asian countries&#8221; to include, but not be limited to, Hong Kong, China, South Korea, Taiwan, Singapore, Malaysia, Thailand, Indonesia, Philippines, India, Vietnam, Pakistan, Russia, and Sri Lanka. Some of these countries may represent developing or emerging markets. The Fund may have significant exposure to emerging market countries.<br/><br/>The Fund generally invests in equity securities, which consist primarily of common stocks, preferred stocks, depositary receipts, and convertible securities, but may also include other types of instruments, such as equity-linked securities, real estate-related companies, and real estate investment trusts issued by Asian real estate companies. The Fund may invest in companies of any market capitalization. While the Fund intends to diversify its investments across a number of different countries, including emerging market countries, it may, under unusual circumstances, invest all or a significant portion of its assets in a single Asian country. To a more limited degree, the Fund may also invest in U.S. and foreign debt securities. Due to the nature of the securities in which the Fund invests, it may have relatively high portfolio turnover compared to other funds.<br/><br/>The portfolio manager applies a &#8220;bottom up&#8221; approach in choosing investments. In other words, the portfolio manager looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund&#8217;s investment policies. The portfolio manager will also analyze each company from a macro perspective taking into consideration any important themes or issues that may impact the investment environment in certain regions or sectors and to estimate regional market risks.<br/><br/>The Fund may also take long or short positions in derivatives, which are instruments that have a value derived from, or directly linked to, an underlying asset, such as equity securities, fixed-income securities, commodities, currencies, interest rates, or market indices. For purposes of meeting its 80% investment policy, the Fund may include derivatives that have characteristics similar to the securities in which the Fund may directly invest. The types of derivatives in which the Fund may invest include options, futures, swaps, warrants, and forward exchange contracts. The Fund may use derivatives to hedge, to earn income or enhance returns, as a substitute for securities in which the Fund invests, to increase or decrease the Fund&#8217;s exposure to a particular market, to adjust the Fund&#8217;s currency exposure relative to its benchmark index, to gain access to foreign markets where direct investment may be restricted or unavailable, or to manage the Fund&#8217;s risk profile. The Fund&#8217;s exposure to derivatives will vary, is not limited to those derivatives listed, and could be significant at times. The biggest risk is that the Fund&#8217;s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.<br/><br/><b><i>Value Investing Risk.</i></b> Because different types of stocks tend to shift in and out of favor depending on market and economic conditions, &#8220;value&#8221; stocks may perform differently than other types of stocks and from the market as a whole, and can continue to be undervalued by the market for long periods of time. It is also possible that a value stock will never appreciate to the extent expected by the Fund&#8217;s portfolio manager.<br/><br/><b><i>Market Risk.</i></b> The value of the Fund&#8217;s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager&#8217;s belief about a company&#8217;s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund&#8217;s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.<br/><br/><b><i>Growth Securities Risk.</i></b> The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be &#8220;growth&#8221; companies may be more volatile than other stocks and may involve special risks. If the portfolio manager&#8217;s perception of a company&#8217;s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund&#8217;s returns. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, &#8220;growth&#8221; stocks may perform differently from the market as a whole and other types of securities.<br/><br/><b><i>Special Situations Risk.</i></b> The Fund may invest in companies that demonstrate special situations or turnarounds, meaning companies that have experienced significant business problems but are believed to have favorable prospects for recovery. Special situations may include significant changes in a company&#8217;s allocation of its existing capital, a restructuring of assets, or a redirection of free cash flow. Special situations may also result from: (i) significant changes in industry structure through regulatory developments or shifts in competition; (ii) a new or improved product, service, operation, or technological advance; (iii) changes in senior management or other extraordinary corporate event; (iv) differences in market supply of and demand for the security; or (v) significant changes in cost structure. Investments in &#8220;special situations&#8221; companies can present greater risks than investments in companies not experiencing special situations, and the Fund&#8217;s performance could be adversely impacted if the securities selected decline in value or fail to appreciate in value.<br/><br/><b><i>Nondiversification Risk.</i></b> The Fund is classified as nondiversified under the Investment Company Act of 1940, as amended. This gives the Fund&#8217;s portfolio manager more flexibility to hold larger positions in a smaller number of securities. As a result, an increase or decrease in the value of a single security held by the Fund may have a greater impact on the Fund&#8217;s net asset value and total return.<br/><br/><b><i>Foreign Exposure Risk.</i></b> The Fund may have significant exposure to foreign markets as a result of its investments in foreign securities, including investments in emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund&#8217;s performance than it would in a more geographically diversified portfolio. The Fund&#8217;s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.<br/><br/><b><i>Derivatives Risk.</i></b> Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative&#8217;s original cost, and can therefore involve leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. To the extent the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund&#8217;s losses are theoretically unlimited.<br/><br/><b><i>Real Estate Securities Risk.</i></b> The Fund may be affected by risks associated with investments in real estate-related securities. The value of securities of issuers in the real estate and real estate-related industries, including real estate investment trusts, is sensitive to changes in real estate values and rental income, property taxes, interest rates, tax and regulatory requirements, supply and demand, and the management skill and creditworthiness of the issuer. These factors may impact the Fund&#8217;s investments in foreign real estate markets differently than U.S. real estate markets.<br/><br/><i>An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.</i> 0.0109 <b>PRINCIPAL INVESTMENT RISKS</b> 0.3148 The biggest risk is that the Fund&#8217;s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an Asian equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.<br/><br/><b><i>Foreign Exposure Risk.</i></b> The Fund normally has significant exposure to foreign markets as a result of its investments in foreign securities, including investments in emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund&#8217;s performance than it would in a more geographically diversified portfolio. The Fund&#8217;s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.<br/><br/><b><i>Emerging Markets Risk.</i></b> The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities involve a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on the Fund&#8217;s investments. In addition, the Fund&#8217;s investments may be denominated in foreign currencies and therefore, changes in the value of a country&#8217;s currency compared to the U.S. dollar may affect the value of the Fund&#8217;s investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund&#8217;s performance. Additionally, foreign and emerging market risks, including but not limited to price controls, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, nationalization, and restrictions on repatriation of assets may be heightened to the extent the Fund invests in Chinese local market equity securities (also known as &#8220;A Shares&#8221;). Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve other risks. As of September 30, 2012, approximately 64.4% of the Fund&#8217;s investments were in emerging markets.<br/><br/><b><i>Geographic Concentration Risk.</i></b> Because the Fund intends to focus its investments in a particular geographic region, the Fund&#8217;s performance is expected to be closely tied to various factors such as social, financial, economic, and political conditions within that region or country. Specifically, the Fund&#8217;s investments in Asian issuers increase the Fund&#8217;s exposure to the risks associated with volatile securities markets, adverse exchange rates, social, political and regulatory developments, and economic environmental events (such as natural disasters) which may be particular to Asian countries. Events that negatively affect the fiscal stability of Asian countries may cause the value of the Fund&#8217;s shares to decrease, in some cases significantly. As a result, the Fund is likely to be more volatile than more geographically diverse funds. In addition, many of the economies of the Asian countries in which the Fund invests are interdependent, which may cause them to experience the impact of such events at the same time or may increase the possibility that conditions in one country or region might adversely impact the issuers of securities in a different country or region.<br/><br/><b><i>Market Risk.</i></b> The value of the Fund&#8217;s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager&#8217;s belief about a company&#8217;s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund&#8217;s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.<br/><br/><b><i>Growth Securities Risk.</i></b> The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be &#8220;growth&#8221; companies may be more volatile than other stocks and may involve special risks. If the portfolio manager&#8217;s perception of a company&#8217;s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund&#8217;s returns. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, &#8220;growth&#8221; stocks may perform differently from the market as a whole and other types of securities.<br/><br/><b><i>Derivatives Risk.</i></b> Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities.

These factors may impact the Fund&#8217;s investments in foreign real estate markets differently than U.S. real estate markets.<br/><br/><b><i>Portfolio Turnover Risk.</i></b> Increased portfolio turnover may result in higher costs, which may have a negative effect on the Fund&#8217;s performance. In addition, higher portfolio turnover may result in the acceleration of capital gains and the recognition of greater levels of short-term capital gains, which are taxed at ordinary federal income tax rates when distributed to shareholders.<br/><br/><i>An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.</i> After-tax returns are calculated using distributions for the Fund&#8217;s Class D Shares for the periods following February 16, 2010; and for the Fund&#8217;s Class J Shares, the predecessor share class, for the periods prior to February 16, 2010.

The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.<br/><br/> <b><i>Market Risk.</i></b> The value of the Fund&#8217;s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio managers&#8217; belief about a company&#8217;s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund&#8217;s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.<br/><br/> <b><i>Small-Sized Companies Risk.</i></b> The Fund&#8217;s investments in securities issued by small-sized companies, which tend to be smaller, start-up companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. Securities issued by small-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger companies.<br/><br/> <b><i>Growth Securities Risk.</i></b> The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be &#8220;growth&#8221; companies may be more volatile than other stocks and may involve special risks. If the portfolio managers&#8217; perception of a company&#8217;s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund&#8217;s returns. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, &#8220;growth&#8221; stocks may perform differently from the market as a whole and other types of securities.<br/><br/> <b><i>Foreign Exposure Risk.</i></b> The Fund may have exposure to foreign markets as a result of its investments in foreign securities, including investments in emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund&#8217;s performance than it would in a more geographically diversified portfolio.<br/><br/> <i>An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.</i> <i>janus.com/allfunds</i> 0.2383 <b>Janus Asia Equity Fund</b> seeks long-term growth of capital. <b>EXAMPLE:</b> <b>Janus Emerging Markets Fund </b> seeks long-term growth of capital.

Generally speaking, the &#8220;life sciences&#8221; relate to maintaining or improving quality of life. So, for example, companies with a &#8220;life science orientation&#8221; include companies engaged in research, development, production, or distribution of products or services related to health and personal care, medicine, or pharmaceuticals. The Fund implements this policy by investing primarily in equity securities of U.S. and foreign companies selected for their growth potential. The Fund normally invests in issuers from several different countries, which may include the United States. The Fund may, under unusual circumstances, invest in a single country. The Fund may have significant exposure to emerging markets. The Fund may also invest in U.S. and foreign debt securities. As a fundamental policy, the Fund normally invests at least 25% of its total assets in the &#8220;life sciences&#8221; sector, which may include companies in the following industry groups: health care; pharmaceuticals; agriculture; cosmetics/personal care; and biotechnology.<br /><br />The portfolio manager applies a &#8220;bottom up&#8221; approach in choosing investments. In other words, the portfolio manager looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund&#8217;s investment policies.<br /><br />The Fund may invest its assets in derivatives, which are instruments that have a value derived from, or directly linked to, an underlying asset, such as equity securities, fixed-income securities, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. For purposes of meeting its 80% investment policy, the Fund may include derivatives that have characteristics similar to the securities in which the Fund may directly invest. The Fund may invest in derivative instruments (by taking long and/or short positions) for different purposes, including hedging (to offset risks associated with an investment, currency exposure, or market conditions) and to earn income and enhance returns. 1718 1987 1283 786 677 1556 The Fund pursues its investment objective by investing at least 50% of its equity assets in small-sized companies. The Fund may also invest in larger companies with strong growth potential or relatively well-known and large companies with potential for capital appreciation. Small-sized companies are defined by the portfolio managers as those companies whose market capitalization falls within the range of companies in the Russell 2000<sup style="FONT-SIZE: 85%; VERTICAL-ALIGN: text-top">&#174;</sup> Growth Index. Market capitalization is a commonly used measure of the size and value of a company. The market capitalizations within the index will vary, but as of September 30, 2012, they ranged from approximately $45 million to $4.5 billion. Companies whose capitalization or revenues fall outside these ranges after the Fund&#8217;s initial purchase continue to be considered small-sized.<br/><br/> The portfolio managers apply a &#8220;bottom up&#8221; approach in choosing investments. In other words, the portfolio managers look at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund&#8217;s investment policies.<br/><br/> The Fund may also invest in foreign equity and debt securities, which may include investments in emerging markets. 978 <b>FEES AND EXPENSES OF THE FUND</b> This table describes the fees and expenses that you may pay if you buy and hold Shares of the Fund.

The Example also assumes that your investment has a 5% return each year and that the Fund&#8217;s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: <b>Portfolio Turnover: </b> 0.3582 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or &#8220;turns over&#8221; its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund&#8217;s performance. During the most recent fiscal year, the Fund&#8217;s portfolio turnover rate was 12% of the average value of its portfolio. <b>PRINCIPAL INVESTMENT STRATEGIES</b> 0.2069 The Fund pursues its investment objective by normally investing primarily in a core group of 20-30 common stocks selected for their growth potential.

The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. Common stocks tend to be more volatile than many other investment choices.<br /><br /><b><i>Market Risk</i>.</b> The value of the Fund&#8217;s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager&#8217;s belief about a company&#8217;s intrinsic worth is incorrect.

This gives the Fund&#8217;s portfolio manager more flexibility to hold larger positions in a smaller number of securities. As a result, an increase or decrease in the value of a single security held by the Fund may have a greater impact on the Fund&#8217;s net asset value and total return.<br /><br /><b><i>Foreign Exposure Risk</i>.</b> The Fund may have significant exposure to foreign markets as a result of its investments in foreign securities, including investments in emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions.

In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund&#8217;s performance than it would in a more geographically diversified portfolio. The Fund&#8217;s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.<br /><br /><b><i>Derivatives Risk</i>.</b> Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative&#8217;s original cost, and can therefore involve leverage. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations. <br /><br /><i>An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.</i> 0.114 <b>PERFORMANCE INFORMATION</b> The following information provides some indication of the risks of investing in the Fund by showing how the Fund&#8217;s performance has varied over time.

In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund&#8217;s performance than it would in a more geographically diversified portfolio. The Fund&#8217;s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries.<br /><br /><b><i>Emerging Markets Risk</i>.</b> The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities involve a number of additional risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, or creation of government monopolies, any of which may have a detrimental effect on the Fund&#8217;s investments. In addition, the Fund&#8217;s investments may be denominated in foreign currencies and therefore, changes in the value of a country&#8217;s currency compared to the U.S. dollar may affect the value of the Fund&#8217;s investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund&#8217;s performance. Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve other risks. As of September 30, 2012, approximately 4.3% of the Fund&#8217;s investments were in emerging markets.<br /><br /><b><i>Market Risk</i>.</b> The value of the Fund&#8217;s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases or if the portfolio manager&#8217;s belief about a company&#8217;s intrinsic worth is incorrect. Further, regardless of how well individual companies or securities perform, the value of the Fund&#8217;s portfolio could also decrease if there are deteriorating economic or market conditions. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.<br /><br /><b><i>Growth Securities Risk</i>.</b> The Fund invests in companies after assessing their growth potential. Securities of companies perceived to be &#8220;growth&#8221; companies may be more volatile than other stocks and may involve special risks. If the portfolio manager&#8217;s perception of a company&#8217;s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund&#8217;s returns. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, &#8220;growth&#8221; stocks may perform differently from the market as a whole and other types of securities.<br /><br /><b><i>Concentration Risk</i>.</b> The Fund focuses its investments in &#8220;life sciences&#8221; related industry groups. As a result, the Fund may be subject to greater risks and its net asset value may fluctuate more than a fund that does not concentrate its investments.<br /><br /><b><i>Derivatives Risk</i>.</b> Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative&#8217;s original cost, and can therefore involve leverage. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations.<br /><br /><i>An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.</i> 0 249 Class S Shares Class I Shares Class T Shares 0 <b>FEES AND EXPENSES OF THE FUND</b> 0 0.0091 After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. 0.2465 0 Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-deferred account, such as a 401(k) plan or an IRA. The Fund pursues its investment objective by investing primarily in common stocks selected for their growth potential. Although the Fund may invest in companies of any size, it generally invests in larger, more established companies. As of September 30, 2012, the Fund&#8217;s weighted average market capitalization was $102.8 billion.

In other words, the portfolio managers look at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund&#8217;s investment policies.<br/><br/>The Fund may invest its assets in derivatives, which are instruments that have a value derived from, or directly linked to, an underlying asset, such as equity securities, fixed-income securities, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. The Fund may invest in derivative instruments (by taking long and/or short positions) for different purposes, including hedging (to offset risks associated with an investment, currency exposure, or market conditions) and to earn income and enhance returns. 0.1189 This table describes the fees and expenses that you may pay if you buy and hold Shares of the Fund.

Goff (the &#8220;Research Team&#8221;), select investments for the Fund. The Research Team, comprised of sector specialists, conducts fundamental analysis with a focus on &#8220;bottom up&#8221; research, quantitative modeling, and valuation analysis. Using this research process, analysts rate their stocks based upon attractiveness. Analysts bring their high-conviction ideas to their respective sector teams. Sector teams compare the appreciation and risk potential of each of the team&#8217;s high-conviction ideas and construct a sector portfolio that is intended to maximize the best risk-reward opportunities. Although the Research Team may find high-conviction investment ideas anywhere in the world, the Research Team emphasizes investments in securities of U.S.-based issuers.<br/><br/>Positions may be sold when, among other things, there is no longer high conviction in the return potential of the investment or if the risk characteristics have caused a re-evaluation of the opportunity. This may occur if the stock has appreciated and reflects the anticipated value, if another company represents a better risk-reward opportunity, or if the investment&#8217;s fundamental characteristics deteriorate. Securities may also be sold from the portfolio to rebalance sector weightings.<br/><br/>Mr. Goff oversees the investment process and is responsible for the day-to-day management of the Fund. It is expected that the Fund will be broadly diversified among a variety of industry sectors. The Fund intends to be fully invested under normal circumstances. However, under unusual circumstances, if the Research Team does not have high conviction in enough investment opportunities, the Fund&#8217;s uninvested assets may be held in cash or similar instruments.
